Impact Of Issuing Debt On Shareholders - Essay Example The internal rate of return of the expansion project is expected to far outperform the company’s hurdle rate. The acquisition of Productos Reunidos is also a positive net present value project. However, empirical evidence suggests that market value of the acquiring firm experiences little if any gain after acquisition, and in some cases even losses. Also, the reasons cited by the management and the merger and acquisition committee for acquisition, namely, diversification and PE magic, are wrong. Hence, I recommend Tyneside Electronics to grow internally by investing in the expansion project. Moreover, there are gains from financing the expansion project by leverage, even in the worst case scenario of 10% increase in revenue, as illustrated in section A and B. Also, if the expected return on shares stays constant, I recommend the firm to adopt a D/E ratio of 1, the optimum capital structure.

Uniform Crime Report Essay Example for Free

Uniform Crime Report Essay A Uniform Crime Report is a data series published by the Federal Bureau of Investigation that has been collected since 1930 and has been widely used by criminal justice researchers to collect data on crime. (Maxfield Babbie, 2012) Law enforcement agencies provide the crime data to the Federal Bureau of Investigation, and then the reports are compiled and created. The Uniform Crime Report does not count all crimes that are reported to the police. Part I offenses such as murders and non-negligent manslaughter, forcible rape, robbery, aggravated assault, burglary, larceny theft, and motor vehicle theft are all counted in the Uniform Crime Report. (Maxfield Babbie, 2012) There are a large number of crimes that are not measured in the Uniform Crime Report because they are considered to be Part II crimes. Part II crimes consist of shoplifting, drug sale or use, fraud, prostitution, simple assault, vandalism, receiving stolen property, and other non-traffic offenses. (Maxfield Babbie, 2012) Part II crimes are counted on the Uniform Crime Reports only if that person has been arrested and charged with a crime. These crimes do represent a large number of offenses that occur across the United States. And since they are only reported if a person has been arrested and charged with a crime, this does create some measurement errors in the Uniform Crime Report. In the 1920’s, the International Association of Chiefs of Police formed the Committee on Uniform Crime Reports. (Atlas, 2011) This committee wanted to establish a system of uniform police crime statistics. This committee evaluated various crimes based on how serious the crime is and how frequent that crime occurred as well as the likelihood of it being reported to law enforcement in all areas of the country. (Atlas, 2011) After the studies and evaluations were completed in each state, the Committee completed a plan for crime reporting that became the foundation of the Uniform Crime Report Program in 1929. (Atlas, 2011) Every month, law enforcement agencies across the United States submit results on the amount of Part I index offenses to the Federal Bureau of Investigation. The index offenses consists of criminal homicide: the willful non-negligent killing of one human being by another or a death caused by negligence, attempted killings, and suicides; Forcible rape: the knowledge of raping a female forcibly and against her will and attempts or assaults excluding statutory offenses; Robbery: The taking or attempting to take anything of value from the custody or control of a person or persons by force or threat of force; Aggravated assault: an unlawful attack by one person upon another for the purpose of inflicting severe or aggravated bodily injury with the use of a weapon; Burglary: The unlawful entry of a structure to commit a felony or a theft; Larceny theft: the unlawful taking, carrying, leading, or riding away of property from the possession or constructive possession of another such as bicycles, shoplifting, and pocket-picking; Motor vehicle theft: the theft or attempted theft of a motor vehicle; Arson: any willful or malicious burning or attempt to burn, with or without intent to defraud a house, public building or any other personal property of another. (Atlas, 2011) Arson was not included in the Part I crime index’s originally when the Committee first formed the Uniform Crime Report. It was later added in 1979 to be included on the Uniform Crime Report. Before looking into the Uniform Crime Report statistics, violent crime in Illinois seems to have been on the rise especially the major metropolitan areas like Chicago. Just based on the news reports and changes in the communities that I have seen over the years has led me to believe that violent crime has increased tremendously. But after looking into the statistics more and reviewing the Uniform Crime Reports for the state Illinois I was able to really determine how violent crime was measured and recorded in Illinois. I will be reviewing violent crimes consisting of murder and non-negligent manslaughter, forcible rape, robbery and aggravated assault from the years of 2006 through 2010. I have included a table showing the crime reporting statistics for the state of Illinois from 2006 through 2010. Table 1, State of Illinois The statistics that appear in table 1 from the Uniform Crime Report show that in the categories of aggravated assault, robbery, forcible rape, and murder and non-negligent homicide, the number of violent crimes overall has decreased or stayed approximately the same from the years 2006 through 2010. Aggravated assaults in the years 2006 and 2010 had noticeably dropped while robberies stayed approximately the same throughout the five years with the biggest drop in the years 2006 and 2010 as well. Aggravated assaults in 2006 were reported at 40,858 and 32,042 in 2010. Forcible rape also stayed consistent during the five years with the exception of years 2006 and 2010. In 2006, forcible rape was reported at 4,078 and 3,033 in 2010. Murders and non-negligent homicides were surprisingly reported approximately about the same from 2006 through 2010. That category also had the biggest change in the year 2006 and 2010. Overall, the crimes reported show that crime has had its biggest decrease in the year 2010 in all four crime index categories. There isn’t a significant amount of differences amongst the numbers reported for violent crimes, but there still shows some improvement from the years 2006 through 2010. When looking at other states violent crime statistics between the years of 2006 through 2010 in comparison to Illinois, I reviewed Michigan, Ohio, and Pennsylvania. These three states were similar to Illinois in population. Violent crime trends in Illinois did not mirror these states at all. Tables 2, 3 and 4 show the crime rates between Michigan, Ohio, and Pennsylvania between the years of 2006 through 2010. Table 2, State of Michigan Table 3, State of Ohio Table 4, State of Pennsylvania Although the Uniform Crime Report numbers for these states above are very different from one another, there were some noticeable changes within all four states. While Michigan and Illinois had similar aggravated assaults, Ohio had a significant amount that was less. The biggest difference is shown in the year 2006 where Illinois had 40,858 aggravated assaults, and Ohio only had 15,973. Forcible rapes were pretty consistent in decreases in the four states, but Ohio had the highest reduction from 2006 through 2010. Robberies is also an area where the statistics reported were shown to have decreased consistently in all four states throughout the same years. This was a major similarity between the four states with Illinois reporting the highest robbery crimes amongst Michigan, Ohio, and Pennsylvania. The last crime offense what was looked at was murder and non-negligent homicide. This is another area where it showed a consistent decrease amongst all four states with Ohio having the lowes t amount of murders and non-negligent homicides reported in the year 2010 compared to the other states. Most of the areas in each state showed trends of a consistent pattern even though the numbers reported and shown were different from year to year. Overall, there is a pattern that shows in all four states that violent crimes appear to be decreasing starting from the year 2006 through 2010 which is good. There were some discrepancies that were reported with the forcible rape offenses in the state of Illinois. According to the Uniform Crime Report in the year 2006, Illinois data include arrests made for rapes of male victims. Therefore, Illinois figures for forcible rape include only forcible rape offenses from Rockford, Illinois that had female victims. (Justice, 2007) In other words, Rockford, Illinois is the only part of the state that is submitting data for female victims of forcible rapes whereas the remaining area is not. Therefore the national Uniform Crime Report did not include all of the arrest data. There are other crimes that are not reported in the Uniform Crime Report suc h as drug sale or use, vandalism, simple assault, prostitution, and all other non-traffic offenses. Because of this, a large number of crimes reported are not measured in the Uniform Crime Report. (Maxfield Babbie, 2012) The hierarchy rule is also another measurement error in the Uniform Crime Report that is used by police agencies and the Federal Bureau of Investigation to classify crimes. Under the hierarchy rule, if multiple crimes are committed in a single incident, only the most serious is counted in the Uniform Crime Report. (Maxfield Babbie, 2012) This is what was seen in the crime statistics for Illinois. According to the Uniform Crime Report for Illinois, valid counts for murder, forcible rape, robbery, and aggravated assault were available only for agencies in cities 100,000 and over in population. (Justice, 2007) The only available data generated by the Illinois State Program were totals based upon an incident-level system without indication of multiple offenses recorded within single incidents. (Justice, 2007) Therefore, the Uniform Crime Report hierarchy rule could not be applied in order to convert the state’s data to Summary format. (Justice, 2007) To arrive at a comparable state estimate to be included in national compilations, the Illinois State Program’s totals were reduced by the proportion of multiple offenses reported within single incidents in the National Incident-Based Reporting System database. Data for cities 100,000 and over in population were excluded from the reduction process. (Justice, 2007) Even though there are many measurement errors in the Uniform Crime Report, I still believe that the report is very useful throughout the United States. It gives an estimated figure on violent and property crimes from state to state. This is important because based on the measures of accurately assessing these crimes, more tactical ways to minimize crime amongst police agencies can be developed based on what is being reported in the Uniform Crime Report. We all want our communities to be as safe as possible and this is a great way to start along with monthly meetings about what is being reported in each area of the cities. Works Cited Atlas, N.

Power in Frankenstein :: essays research papers

Most people agree that Victor Frankenstein holds the most power in the text. In creating the monster, he not only has the power to create life but also the power to, indirectly, save or destroy others lives. Critics of his character speculate that Justine could have been saved had be only confessed his actions in Ingolstadt. However, the creature also holds considerable power. For example, he held power over Justine’,s fate when he incriminated her with the necklace. He holds some power over the De Lacy family, as it is his actions in collecting firewood that decide whether or not Felix must work as heavily during the day. In turn, the De Lacy family hold power, unbeknownst to them, over the creature, so much so that he commits himself to living in what is little more than a wooden box for a year. The creature’,s hopes for the future lie entirely on this family, and power of this nature is perhaps the strongest type of power anybody could exert over another being. This is due to the fact that the one who is controlled, ie, the creature, does not realize this and so will never attempt to free themselves from the hierarchy they find themselves in. But it is also evident that someone, or something, exerted great control over the De Lacy family, as they are living an impoverished, isolated lifestyle. The creature’,s account of the family’,s history discovers this fact to the readers, that was in fact the French government. Given the time period, 17--, this is presumably patriarchal to the extreme. While for a while it could be supposed that Felix held power over the government, as he assisted in Safie’,s father’,s jail break, but the latter caught up with him and ultimately ruined him and his family. On this train of thought, Felix’,s family hold power over Safie’,s father, but only while he is imprisoned. Once he is freed, the tables turn, and he breaks his promise to Felix of his daughters hand in marriage. Coming form an Eastern society that is suggested to be even more patriarchal than the Western European culture, a power struggle ensues between Safie, who wishes to marry Felix, and her father, who wants her to return home with him. What is most interesting is the fact that it is Safie, with the assistance of another woman, who eventually gets her own way.

The SDLC

Several different projects may be required during the life of a system, first to develop the original system and then upgrade it later. The primary concern is with getting the system developed and deployed the very first time. One of the key, fundamental concepts in information system development is the Systems Development Life Cycle. The Systems Development Life Cycle is an entire process of building, deploying, using, and updating an information system Satzinger, J. W. , Jackson, R. B. , & Burd, S. D. (2009).Systems development includes four project managers, six system analysts, 10 programmer analysts, and a couple of clerical support employees. This paper has two objectives. The first is to explain the components of a formal SDLC process. The second is to identify types of employees involved in the SDLC process and their roles Although it is difficult to find a single, comprehensive classification system that encompasses all of the approaches, one useful technique is to categoriz e SDLC approaches according to whether they are more predictive or adaptive.In predictive the requirements are well understood and well defined. There is low technical risk. On the other hand in adaptive, the requirements and needs are uncertain. There is high technical risk. The SDLC consist of four groups of activities: planning, analysis, design, and implementation. These activities are sometimes referred to as phases, and they are the elements that provide the framework for managing the project. Throughout the SDLC, the analyst’s role as a project manager is being responsible for initiating, planning, executing, and closing down the systems development project Satzinger, J.  W. , Jackson, R. B. , & Burd, S. D. (2009).Project management is arguably the most important aspect of an information systems development project. Effective project management helps ensure that systems development projects meet customer expectations and are delivered within budget and time constrain ts. A project manager will periodically review the status of all ongoing project task activities to assess whether the activities will be completed early, on time, or late.Moreover, project scheduling and management require that time, costs, and resources be controlled. The roles and responsibilities of developers are large in number. The primary responsibilities are: to write code or documentation patches or contribute positively to the project in other ways. A developer’s contribution is always recognized. The software developer has to evaluate, assess and recommend software and hardware solutions. Develop software, architecture, specifications and technical interfaces.Design, initiate and handle technical designs and complex application features. Initiate and drive major changes in programs, procedures and methodology. And Coordinate with other developers and software professionals. Once system developers have accumulated the user requirements for the new system, analysts proceed to the system design stage. A system analyst researches problem, plans solutions, recommends software and systems, at least at the functional level, and coordinates development to meet business or other requirements Hughes, A.  (2013).A system analyst may identify, understand and plan for organizational and human impacts of planned systems, and ensure that new technical requirements are properly integrated with existing processes and skill sets. The analyst should also plan a system flow form the ground up, perform system testing, deploy the completed system, document requirements or contribute to user manuals, and help programmers during system development. Whenever programmers need help the system analyst provides use cases, flowcharts or even database design.The most difficult task in system analysis is to identify the specific requirements that the system must satisfy. System development projects are organized around the systems development life cycle (SDLC), and phase s the SDLC include activities that must be completed for any system development project. These phases are project planning, analysis, design, implementation, and support. Any organization can develop an information system in lots of ways. . System development includes four project managers, six system analysts, 10 programmer analysts, and a couple of clerical support employees.The role of a project manager is organizing and directing other people to achieve a planned result within a predetermined schedule and budget. The project manager can be defined as the processes used to plan the project and then monitor and control it. The other systems analysts assigned to the team are experienced developers with strong analytical skills, as well as experience in managing and controlling projects Hughes, A. (2013). Some developers think of a model as documentation produced after the analysis and design work is done.

Functionalism, Conflict, and Internationalism Essay

The three theories I plan to discuss are Functionalism, Conflict, and Internationalism with education. The need for these theories is what actually makes the system in education work, with the teachers, parents, school boards and committees the institution of education continues to function. The first theory is Functionalism and is about the study by Lawrence Kohlberg. It has been forty-three years since Lawrence Kohlberg published his doctoral dissertation characterizing six stages of moral development and fourteen years since his death. During this period, much has been written that has discredited stage theory and the overarching use of justice as a â€Å"first principle† of moral development. Yet Kohlberg’s evolving moral theory continues to be used as a theoretical basis for moral development research and to influence teacher education. While some educators have dismissed Kohlberg’s approach as wooden and â€Å"fossilized,† it continues to be central to what teachers know about, and how they think about, moral development. 2] Indeed, one author suggests that â€Å"every psychology textbook published in the last quarter-century touches upon Kohlberg’s work. â€Å"[3] This consistent message, coupled with continued public talk about character development and moral education in schools, makes it likely that Kohlberg’s stage theory continues to influence classroom practice, consciously and unconsciously, across the United States, Henry, (2001). By exposing the structural-functionalist roots of Kohlberg’s theory, this essay raises concerns about the application of Kohlberg’s ideas in the classroom. Fundamentally, Kohlberg focuses on individual development, a universal conception of justice, and universalizability do not translate well to the institutional-level application that he hoped his Just Community Schools would provide. What Kohlberg failed to realize was that a collection of individuals using a Functionalism, Conflict, and Interactionism in Education universal conception of justice in consistent ways across situations (morally mature individuals by Kohlberg’s standards) did not necessarily create a moral community. In a moral community, the degree to which individuals have grown along a continuum of moral development should not be of greater importance than the ability of community members to work together to detect and solve moral problems. Henry, (2001) Foundational to the Just Community model was Kohlberg’s belief that schools were important locations for the socialization of children into broader society. School was a child’s first formal introduction into society at large. By going to school â€Å"the child learns to fill the expected public roles of a member of his society† (LKA, 21). Part of the power of schooling was the teaching of lessons necessary for successful life outside of school. In particular, Kohlberg stressed that students needed to gain an increased awareness of themselves in categorical terms. [7] In other words, he and his colleagues claimed that students needed to learn the categorical expectations to which they would be held publicly accountable and that school had an important function to play in teaching these lessons: [T]he child has to learn to be one among a crowd of peers in a classroom that is run by a relative impersonal authority figure who gives orders a power to wield praise and blame. What the child learns about how to handle â€Å"the crowds, the praise, and the power† will, from this point of view, give shape to her public morality: her conception of how one ought to act to get along and even prosper in the public domain (LKA, 21). Functionalism, Conflict, and Interactionism in Education These statements make it clear that Kohlberg saw schools as important locations for gradually imbuing children with the expectations they would meet as adults, Henry, (2001). While Kohlberg was focused on the individual the theory of functionalism doesn’t work. It works as a whole at a much larger level, the macro level, the institution of the schools. These system need function to run and for student to learn. With this in place there would dis-function children would not be able to learn and through the learning they learn how to enter into society and act accordingly in their roles into adulthood. The theory of Conflict in regards to education they are there, but one that comes to mind is the quality of the education that is given to students today. All the students are not looked at the same, if they come from a poor family or a minority family they are not thought of as equal in intelligence as the white middle to higher class of student. According to Conflict Theory, society is: A struggle for dominance among competing social groups (classes, genders, races, religions, etc. ). When conflict theorists look at society, they see the social domination of subordinate groups through the power, authority, and coercion of dominant groups. In the conflict view, the most powerful members of dominant groups create the rules for success and opportunity in society, often denying subordinate groups such success and opportunities; this ensures that the powerful continue to monopolize power, privilege, and authority. You should note that most conflict theorists oppose this sort of coercion and favor a more equal social order. Some support a complete socioeconomic revolution to socialism (Marx), while others are more reformist, or perhaps do not see all social inequalities stemming from the capitalist system Functionalism, Conflict, and Interactionism in Educational (they believe we could solve racial, gender, and class inequality without turning to socialism). However, many conflict theorists focus on capitalism as the source of social inequalities. The primary cause of social problems, according to the conflict perspective, is the exploitation and oppression of subordinate groups by dominants. Conflict theorists generally view oppression and inequality as wrong, whereas Structural-Functionalists may see it as necessary for the smooth running and integration of society. Structural-Functionalism and Conflict Theory therefore have different value orientations but can lead to similar insights about inequality (e. g. , they both believe that stereotypes and discrimination benefit dominant groups, but conflict theorists say this should end and most structural-functionalists believe it makes perfect sense that subordinates should be discriminated against, since it serves positive social ends). Conflict theory sees social change as rapid, continuous, and inevitable as groups seek to replace each other in the social hierarchy, McLeod, (2004). In contrast to Structural-Functionalists, who argue that the most talented individuals occupy the highest positions, conflict theorists argue that dominant groups monopolize positions of power, maintaining power from generation to generation and keeping subordinate groups out. Also in contrast to Structural-Functionalists, who argue that the most important positions in society are the best rewarded, conflict theorists argue that dominant groups get inordinate power to define which positions are socially rewarded. Highly-paid positions are not necessarily most important for society, they argue, but keep power in the hands of the privileged and powerful, McLeod, (2004). If conflict theory really see social change coming than that may mean the educators of this country may be starting to focus on the student and their intelligence instead of their financial status or race. Functionalism, Conflict, and Interactionism in Education The last theory Interactionism theory views society as the product of individuals’ interaction with each other. Through the process of socialization, people learn values, attitudes, and actions that they deem to be correct. People are exposed to a set of reinforcements to maintain or change those views and actions. Learning theory helps explain why people view others in particular ways, such as who is good and who is bad. Our views may have little to do with objective reality. Learning theory may also explain the process in which people come to engage in behaviors that others find problematic, such as embezzling or prostitution. As Sutherland (1940) notes, people learn the motivations, beliefs, and actions to engage in behaviors that some may find problematic. Labeling theory explores how people socially construct reality. People in positions of power and authority have the ability to label an activity as problematic or acceptable; people in lower social positions are less likely to persuade others to stick with their definition of the situation. This is why elites are able to define a situation that benefits them as good, while others may regard it as troublesome. It also helps explain why people in lower classes are more likely to be perceived as the cause of problems, and why elites escape that definition. The reality of any social situation depends on how people define it. For example, when college students drink alcohol, is it partying, is it normal, is it binge drinking, is it alcohol abuse, are they a social drinker, a problem drinker, do they use it or abuse it? We may wish to determine how we will label the alcohol consumption based on when they drink, with whom they drink, how much they drink, what they drink, and what they do when they are drinking. Is the drinking a personal problem, a campus problem, or a social problem? These distinctions areFunctionalism, Conflict, and Interactionism in Education determined arbitrarily through the process of labeling. Functionalism, Conflict, and Interactionism Functionalism, Conflict, and Interactionism underlying conditions probably existed for a long time before it was identified as an issue. The disagreement over whether something is a problem, how much of a problem it is, what and who caused it, and how it should be addressed is all a product of social construction created through the process of interaction, Vissing, (2011). I believe that between parents, teachers, students and the communities if they would allow each of themselves to be treated as people, students and human beings the educational process would be easier and more pleasurable experience and a happier and healthier environment. I know that is an impossibility but if were something even a few people would work at it may change the educational field a little bit at a time. To bring these three theories together to have a functional system, bring students in as one instead of the higher class and more social and control the groups of kids and the way they stand against each other there might be a chance to bring our education back on line and educate the students the way they should be educated and ready for the world after high school.

Art schools in Finland. A variety of choice

Art schools in Finland. A variety of choice Art and design schools in Finland We all know that Scandinavian teaching differs from what we are used to in America and the rest of Europe, so learning about the biggest schools in the area will help you decide where to apply. Here are some of the best places you can enroll to, if you are fond of art disciplines: Theatre Academy Helsinki. This is an establishment, that is not so old, yet its popularity is distinctly noticeable among young people, who want to pursue the path of fine arts. The academy is international, always welcoming students from abroad as if they were born and raised under the cold sun of Oslo, and features some of the greatest theatre courses that are available throughout the country. If you are wondering on how to apply, you can visit the academy’s website, and find a program in the English language. There are also courses, lectured in Finnish and Swedish, and you can choose the level of complexity that fits you most. Aalto University School of Arts, Design and Architecture. This university is famous for the variety of programs, which are provided to students annually. One of the most well-known courses, allowing students to broaden their knowledge on art and design, is the Artist-in Residence program, facilitating to enroll students from abroad and encouraging young designers to participate in the exchange studies, organized by the Finnish student community. It is undoubtedly an awesome opportunity for anyone, who is remotely interested in arts, as it helps the promising designers to build their careers from the university benches. Finnish Academy of Fine Arts. Each year, students are invited to choose an individual program, which allows them to learn about their heart’s desire. This is called an introductory program, and it includes general lectures on history, photography and the works of art. Another benefit to the study plan Finnish academy provides is the ability to pick an individual study plan. You can take advantage of the free hours by applying to a side job or having art practice in the local gallery or a museum. Finnish Academy of Fine Arts recently became a part of the Scandinavian project, intended to spread knowledge about higher education in Finland. Sibelius Academy. Sibelius Academy is the one to provide the best musical education in Finland. It also encourages young people from all over the world to come to Finland and try themselves as aspiring arts students. The national tradition of music is highly respected and well maintained within the walls of this educational establishment, and you can learn a lot about Scandinavian tunes as well. The Academy’s aim is to promote international relations on the highest level and attract students from Europe. They also organize junior classes, which are established to prepare teenagers for their future careers in music departments, whether they are planning to enter Sibelius Academy or not. This is an excellent opportunity to test your strength and sort of skim the surface before you immerse in the world of art. Nordic Art School. This is, perhaps, one of the most innovative and contemporary establishments in Finland, located on the west coast of the country. The study plan is unique: it offers a chance to visit two-week long workshops, attended by famous artists and learn from the best in the good sense of a word. Nordic Art School has a two-year program, with the third year being dedicated to the advanced studies of the chosen discipline, and is never short on students, who want to try themselves in different spheres of knowledge with a touch of creativity and futuristic approach.

Free Essays on Overpopulation

China?s One-Child-Policy By: Kevin In 1950, the world human population numbered 2.5 billion. In 1987, the global human population has doubled since 1950, and for the first time, it has exceeded the 5 billion mark. Furthermore, with the continuation of this growth pattern, estimated by demographic researchers, this number is projected to double once more in about 40 years (Raven 48). The rapidly population has caused many incalculable effects on the earth, and scientists have been warning the world of such costly events. According to their studies, tropical forests, equivalent to the size of Washington state, which measures about 17 million hectares, disappear every year, and the disappearance has contributed to the to rising of global temperatures (Piotrow, and Green C3). Eventually, long-turn deforestation will ultimately lead to the extinction of the majority of plant, animal, and microorganism species (Raven 49). In addition, the reduction in fish catches caused by polluted oceans, the piling up of refuse in the ci ties, the worsening air, and water quality, the spread of poverty, and the dwindling supply of food for the growing number of people, have all triggered scientists to urge the nations of the world to slow human population growth (Piotrow, and Green C3). Further, according to researchers, about ninety-five percent of this runaway population growth occurs in the developing countries of Africa, Asia, and Latin America, and with less ability to cope with the increasing number, many of the most critical environmental problems are also taking place there (Raven 48). Among these nations, China is a country notoriously know as the world?s most populous country, has taken the foreseeable which disaster seriously, and for more than two decades, it has launched various policies to contain its population growth.

How to Measure Motion in Plate Tectonics

How to Measure Motion in Plate Tectonics The lithospheric plates are the sections of Earths crust and upper mantle that move- very slowly- over the lower mantle below. We know that these plates move from two different lines of evidence- geodetic and geologic- which allow us to trace their movements back in geologic time. Geodetic Plate Motion Geodesy, the science of measuring the Earths shape and positions on it, allows us to measure plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earths surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell. The longer we record this information, the more accurate it becomes, and in much of the world, the numbers are already quite precise. Another thing GPS can show us is tectonic movements within plates. One assumption behind plate tectonics is that the lithosphere is rigid, and indeed that is still a sound and useful assumption. But parts of the plates are soft in comparison, like the Tibetan Plateau and the western American mountain belts. GPS data helps us separate blocks that move independently, even if only by a few millimeters per year. In the United States, the Sierra Nevada and Baja California micro-plates have been distinguished this way. Geologic Plate Motion: Present Three different geologic methods help determine the trajectories of plates: paleomagnetic, geometric, and seismic. The paleomagnetic method is based on the Earths magnetic field. In every volcanic eruption, iron-bearing minerals (mostly magnetite) become magnetized by the prevailing field as they cool. The direction in which theyre magnetized points to the nearest magnetic pole. Because oceanic lithosphere forms continuously by volcanism at spreading ridges, the whole oceanic plate bears a consistent magnetic signature. When the Earths magnetic field reverses direction, as it does for reasons not fully understood, the new rock takes on the reversed signature. Thus most of the seafloor has a striped pattern of magnetizations as if it were a piece of paper emerging from a fax machine (only its symmetrical across the spreading center). The differences in magnetization are slight, but sensitive magnetometers on ships and aircraft can detect them. The most recent magnetic-field reversal was 781,000 years ago, so mapping that reversal gives us a good idea of plate movements in the most recent geologic past. The geometric method gives us the spreading direction to go with the spreading speed. Its based on the transform faults along the mid-ocean ridges. If you look at a spreading ridge on a map, it has a stair-step pattern of segments at right angles. If the spreading segments are the treads, the transforms are the risers that connect them. Carefully measured, these transforms reveal directions of spread. With plate speeds and directions, we have velocities that can be plugged into equations. These velocities match the GPS measurements nicely. Seismic methods use the focal mechanisms of earthquakes to detect the orientation of faults. Although less accurate than paleomagnetic mapping and geometry, these methods are useful for measuring plate movements in parts of the globe that arent well mapped and have fewer GPS stations. Geologic Plate Motion: Past We can extend measurements into the geologic past in several ways. The simplest one is to extend paleomagnetic maps of the oceanic plates out from the spreading centers. Magnetic maps of the seafloor translate precisely into age maps. These maps also reveal how the plates changed velocity as collisions jostled them into rearrangements. Unfortunately, the seafloor is relatively young, no more than about 200 million years old, because it eventually disappears beneath other plates by subduction. As we look deeper into the past, we must rely more and more on paleomagnetism in continental rocks. As plate movements have rotated the continents, the ancient rocks have turned with them, and where their minerals once indicated north, they now point somewhere else, toward apparent poles. When you plot these apparent poles on a map, they appear to wander away from true north as rock ages go back in time. In fact, north does not change (usually), and the wandering paleo-poles tell a story of wandering continents. Together, the methods listed above allow us to produce an integrated timeline of the movement of the lithospheric plates, a tectonic travelogue that leads smoothly up to the present.

Management - Strategy Process Essay Example | Topics and Well Written Essays - 2500 words

Management - Strategy Process - Essay Example The word strategy was introduced by Sun Tzu in his book The Art of War though at that time he discussed about the military strategy (Tzu, 1971). The main concept behind using of word strategy was to gain advantage over something or someone and in business strategy has been defined as a comprehensive and integrated plan that has been devised to make sure that the main objective of the organization is achieved (Glueck, 1980). Strategy has been used by firms globally to identify what the organization would like to achieve and how it is going to achieve therefore the importance of strategy becomes very vital as proper strategic planning will influence the future of the organization and it will define whether the organization would be able to achieve success or not. Strategic management in the last few years have become a field for the managers which helps them in managing STRATEGY PROCESS Devising strategy for the management has become an important task as it leads to the success or fail ure of the organization. ... Plan 2. Ploy 3. Pattern 4. Position 5. Perspective 1. Strategy as a Plan Plan is defined as the first P of the 5Ps of Strategy as proposed by Mintzberg. Strategy is about planning in order to achieve something or in order to deal with certain situation. Planning involves guidelines that have to be followed to achieve the main objective of the organization. So, this definition of strategy leads to two important characteristics of strategy which are: Planning or strategy has to be made in advance There is an objective or purpose behind formulation of strategies (Henry, Mintzberg, Quinn, & Cliff, 1992) Managers use different tools like SWOT and TWOS to plan their actions according to what they have and what they do not have along with the opportunities that exist in the market that they can exploit. 2. Strategy as Ploy Strategy can be described as a ploy as well with the aim to get the better of competitors. According to Mintzberg (2002) with the ploy of outsmarting the competitors and disrupting or discouraging them, strategy can be considered as a ploy as well. Scenario analysis is one of the tools that have been used by managers to analyze the situation of the company against competitors. 3. Strategy as Pattern Strategy according to Mintzberg (1987) is also defined as a pattern as using the word strategy with plan only is not sufficient. Pattern means consistency in actions and consistency in the way things are managed and done. It has been explained that patterns are realized strategy whereas plans are intended strategies. 4. Strategy as Position Strategy is also defined as position which refers to how the management decides to position the organization in the market. With this definition, the

Tax corporate Essay Example | Topics and Well Written Essays - 250 words

Tax corporate - Essay Example For many small businesses such as Northwest Brand Inc. often all major business investors are employees of the firm (Thomas and Keith, 1994). The business can avoid double tax through distributing their earnings to the corporation’s staff in form of wages and fringe benefits. Although the individual workers have to pay income tax, the Northwest Brand Inc Corporation is able to deduct employee’s wages and other benefits paid to its workforce in form of business expenses hence firm can comfortably avoid paying tax on the expense amount. Similarly, small businesses distributions to employees who are owners of the business accounts for all of the company’s income, ultimately nothing are left that can be subjected to corporate tax. In a situation where the company’s income is left in the business, this will normally be retained in order to finance future business expansion. Thorough this amount will be subjected to corporate tax. The charged rate is often lower compared to those paid by individuals. Larger corporations are unlike small businesses, are more likely to have investors that are not employed by the business. Under this circumstance, the firm can not distribute corporate profits to them as part of their remunerations among other business related incentives, which are able to avoid double taxation as it can be done under businesses that owners are among the workforce. However, they are able to avoid double taxation just like the small businesses (Ted and Robert, 1999). A typical case can be a non-active shareholder is referred to as the business consultant. Since payment to business consultants are tax-deductible expenses rather business expenses rather than dividends. It is may be difficult to include business owners to the corporation’s payment arrangement, for instance through including investors as part of the business directors. In order to obtain relief business investors from double tax, use tax-relief saving

Reflective Report Essay Example | Topics and Well Written Essays - 2500 words

Reflective Report - Essay Example When it comes to being â€Å"dependable†, it is always my best interest to create a remarkable atmosphere within myself in order for others to generate among themselves a certain level of trust in me. I have not thought about it that others could actually see it in me, but based on understanding of my generic competencies, I am capable of initiating a positive response to important things that somebody might entrust to me. That is why I totally agree with the three specific statements I received from the three respondents who told me something about my being dependable. What matters at this point is the fact that there is a positive consistency of what I thought about myself and what others could tell about how I could be relied on certain things. The problem with this is that these respondents might have just seen me based on the standpoint of generic competencies or areas of effectiveness, which I presume common to all people especially with high level of â€Å"dependabilit y†. After all, they still have many things to learn about me. People with high level of dependability are consistently doing the same level of things the way I do. There are no other special things they might observe at this point just the way I do. This is how I view how others might have tried to take a look at my dependability and they based it on the common standard that organizations usually employ to look out the best for others. However, in my case, my being dependable does not have any consistent link with my performance in an organization. This is really who I am. This is my lifestyle. Everything about my dependability does not need to be associated with my performance in an organization. It is just really part of being me that I just do not like not to guarantee others a certain level of trust on my potential or worth as a person. It is integral part of my personality which boils down to the kind of behavior I might have carried at this moment. So at this point, I co uld say my being dependable is unique due to the point that it is tantamount of who I am at present. It is just a bit encouraging that people around me could actually see outside who I am inside. However, I just do not have a remarkable proof that what they actually see in me is who really I am inside, which could substantially tell something more about my uniqueness as a person. However, due to the statements I received from the target respondents, I have finally validated the uniqueness and innermost part of my being as one reliable enough to be entrusted with things in an organization. However, as of now I could clearly say that with the change of my actual behavior, my uniqueness as a person would eventually banish. After all, being dependable is something intrinsic that I found could not be influenced by an organization as I consider it enough as a lifestyle, which changes my perspectives and actual behavior. The other emergent theme that I come to formulate about the feedback I received from my respondent is â€Å"integrity†. The three feedbacks associated with this theme are all consistently pointing to the idea that I am true to my words, which positively builds a positive impression for my identity. As I considered myself dependable, integrity perhaps is strongly associated with dependability as this remarkably

Queastion - Essay Example Muhammad captured the Mecca city later in 630 after the Mecca’s population surrendered. Mecca community accepted Islamic religion and recognized Muhammad as the supreme leader. However, quite a number of tribes were against the Muhammad’s teachings and religion. Muhammad later died leaving no message about the leadership and future of Islamic religion. A new leader was immediately declared by the top advisers of Muhammad, and Abu Bakr was chosen as the leader, However, Unlike Muhammad whose leadership style was well known, Abu Bakr was referred as the successor of Muhammad. Abu Bakr took over most parts of Arabia in his two year leadership. Tribes that were against Islamic authority faced Abu Bakr army under the leadership of Khalid ibn alwalid. The takeover of Arabia by Muslim community led to the establishment Caliph, the central control that formed strong alliance between Arabs and the Muslim community. This was one of the merits of growth and power of Islamic religion because coalition between Muslim communities led to formation of strong army. Establishment of a strong army after formation of Caliph led to the capture of other territories such as Byzantine Empire. Other cities were also captured in Iraq after the battle between Muslim troops and the Persians. New leadership of Muslim community continued the spread of Islamic religion. After the death of Abu Bakr, Umar led on capturing other territories such as Iran and some parts of Asia, with thcConquest being also expanded to northern parts of Africa and to Europe. Muhammad being anti-Christ offered death threats to those who refused to convert to Islam. Additionally, his teachings motivated soldiers in war, and were told that those who died fighting for him would be speared during the Day of Judgment in heaven. Syrians and Egyptian Christians accepted Islamic religion easily because they could not bear hardships they were facing from Christianity religions such as

Did Rousseau correctly argue that previous philosophers had not gone Essay

Did Rousseau correctly argue that previous philosophers had not gone back far enough in search of the state of nature - Essay Example Thus, although the term ‘State of Nature’ refers to a logical construction, it does not necessarily refer to a historical period, although in the early period of human existence when organised societies with laws did not exist, individuals were free to do what they wanted based on their natural desires, psychological makeup, interests and situations, etc. It is possible to argue that humans living in isolation, far removed from the present-day civilisation without any contact with organised societies will illustrate human behaviour in a state of nature without any fabricated laws to impinge on their behaviour. In a state of nature, there were no kings and no government to impose their will on humans. The State of Nature in Rousseau’s Philosophy Rousseau employs the device of state of nature to depict the conditions under which man existed in natural conditions to argue that in the pure state of nature man’s existence would be peaceful and contented. ... Thus, Rousseau presents a belief in the natural goodness of man who had abhorrence for giving consent to others to govern, or for entering society. Rousseau places an emphasis on historical context when thinking about the state of nature rather than considering this notion in terms of a hypothetical context. For Rousseau, the state of nature is a pre-political condition that existed prior to man acceded to the social contract to lose his natural freedom while gaining civil freedom, property and the relative protection of the group. 6 Rousseau suggests that in the state of nature, people did not know each other enough to interfere with each other, but they did present normal moral values, which the social contract for living in a society tarnishes. However, because Rousseau takes a historical rather than a hypothetical view of the state of nature concept, it makes sense to ask whether at any time in history, man has been able to demonstrate the capacity for not succumbing to immoral b ehaviour in relation to others. Certainly, religious doctrine contained in the old testament of the Bible does not support the views presented by Rousseau about man in the state of nature because ever since the time of Genesis, man has demonstrated moral flaws even in dealings within the same family. Thus, it will appear that Rousseau’s arguments concerning the state of nature present flaws, and it makes sense to examine his views in comparison to other noted political theory philosophers, especially those that lived before him. Rousseau’s concept of an early state of nature presents men and women as solitary animals that come together only to reproduce. 7 8 Although, a mother in the

Discussion Questions - Essay Example s still a big field for most business people and academics to be concerned with it, especially in todays connected and digital world, enhanced by advanced information and communications technologies like the cell phone and the Internet. These inventions in improved communications has also presented a new set of challenges for marketing professionals because of the rapidity of these changes and with it, the speed by which information travels in the World Wide Web by way of dissemination. The influence of the Internet today reaches far and wide; it also influences daily lives in many ways because it has become ubiquitous as more people get connected on-line with the rise or growth in the Internet penetration. The sheer omnipresence of the Internet has presented new opportunities and problems for marketeers as they struggle to connect with their consumers in a digital world. An example of this is the rise of so-called on-line communities put up by the firms to help them connect with buyers but has presented some difficulties for them in most instances, because of their failure to recognize the four pillars of a successful hyper-sociality in tribalization efforts (Moran & Gossieaux, 2010, p. 238) and the primary reason for shutting these sites down. Many big firms, especially global enterprises, have resorted to use of a fancy integrated marketing communications (IMC) but the practice also has its drawbacks. In particular, not many people know or understand what it actually means, because it is still an emerging discipline. It is still in infancy and there is a dearth of literature on the subject (Kitchen, Kim & Schultz, 2008, p. 532) such that what happened is that practice has instead gone ahead of the theories on IMC. The way to counter this seeming ignorance is that proposed by using a consumer-centric perspective that combines both IMC and relationship marketing to sustain loyalty (Finne & Gronroos, 2009, p. 180) among consumers of the company which transcends

Edgar Allan Poe Essay Example for Free

Edgar Allan Poe Essay Edgar Allan Poe, those who are familiar with that famous name always allow a chill to run down their spines when they hear it. Poe has always been known for his dramatic and eerie writing style that has entertained readers for centuries. Of course we, as the reader, believe it is simply his brillance that sends a cold shudder through our bodies as we curl up on the couch with The Raven or The Masque of the Red Death, but there is still something more that we can attribute to his writing style. The techniques Poe used in his many stories are what created the fantastic sensation of acutally being a part of the story. In the following paragraphs, I will discuss the chilling techniques this legendary figure, Edgar Allan Poe, used to rope in his reader into the horrible, grotesque, and disturbing world of Prince Pospero and the age of The Red Death. Poe provided us with three major techniques to lead us through this disquieting and disconcerting world that is the reality of Prince Prospero, Poe provided us with, setting, tone, and props. Simply using these three sutble yet powerful techniques, Poe has created an imaginative and mind-boggling universe. First of all, Poe introduced us with surreal, but profound imagery to paint the landscape and life of Prince Prospero and his friends. Setting, one of the most dominant techniques in this short story, can be find around every corner of Prince Prosperos dark maze. Poe described seven rooms that connected to each other in a sick and twisted maze. In order to leave this maze you had to walk through all seven rooms which ranged from color to color and when you finally reached the end you found yourself inside a room, closely shrouded in black velvet tapestries that hung all over the ceiling and down the walls, falling in heavy folds upon a carpet of the same material and hue. This obviously represented the room of the red death and the eventual downfall all the masqueraders would certainly meet.

Biological Effects Of Radiation

Biological Effects Of Radiation Radiation describes a process in which energetic particles or waves travel through a medium or space. There are two distinct types of radiation; ionizing and non-ionizing. The word radiation is commonly used in reference to ionizing radiation only having sufficient energy to ionize an atom but it may also refer to non-ionizing radiation example like radio waves or visible light. The energy radiates travels outward in straight lines in all directions from its source. This geometry naturally leads to a system of measurement and physical that is equally applicable to all types of radiation. Both ionizing and non-ionizing radiation can be harmful to organisms and can result in changes to the natural environment. Radiation with sufficiently high energy can ionize atoms. Most often, this occurs when an electron is stripped from an electron shell, which leaves the atom with a net positive charge. Because cells are made of atoms, this ionization can result in cancer. An individual cell is made of trillions of atoms. The probability of ionizing radiation causing cancer is dependent upon the dose rate of the radiation and the sensitivity of the organism being irradiated. Alpha particles, Beta particles, Gamma and X-Ray radiation, and Neutrons may all be accelerated to a high enough energy to ionize atoms. Radiation includes alpha particle, beta particle, and gamma particle. Alpha particle: In alpha particle, the spontaneous process of emission of an alpha particle from a radioactive nucleus. Alpha particle is generally termed as alpha decay. An alpha particle is emitted by a heavy nucleus. The nucleus, called parent nucleus has a very large internal energy and is unstable. An alpha particle is a helium nucleus having two protons and two neutrons. When two electrons orbiting around the nucleus of helium atom are knocked out completely, we have doubly ionized helium atom known as alpha particle. Beta particle: a beta-particle is a fast moving electron. The spontaneous process of emission of beta-particle from a radioactive nucleus is called beta decay. Beta decay is of three types: beta-minus, beta-plus, and electron capture. Beta-minus: beta-minus is like an electron. It is surprising that nucleus contains no electron, then a nucleus can emit electron. In the neutron inside the nucleus is converted in to a proton and an electron like particle. This electron like particle is emitted by the nucleus during beta-decay. In beta-minus decay, neutron in the nucleus is converted in to a proton and a beta-minus particle is emitted so that the ratio of neutron to proton decreases and hence the nucleus becomes stable. Beta-plus: In a beta-plus decay, a proton is converted in to a neutron and a positron is emitted if a nucleus has more protons than neutrons. Electron capture: In electron capture, nucleus absorbs one of the inner electrons revolving around it and hence a nuclear proton becomes a neutron and a neutrino is emitted. Electron capture is comparable with a positron emission as the processes lead to the same nuclear transformation. However, in electron capture occurs more frequently than positron emission in heavy elements. This is because the orbits of electrons in heavy elements have same radii and hence orbital electrons are very close to the nucleus. Gamma ray: Gamma rays are the high energy packets of electromagnetic radiation. Gamma radiations have high energy photons. They do not have any charge and their relative rest mass is zero. Gamma-decay it is the spontaneous process of emission of high energy photon from a radioactive nucleus. When a radioactive nucleus emits a beta particle, the daughter nucleus is excited to the higher energy state. This excited nucleus rays are emitted by the daughter nucleus so it is clear that the emission of gamma rays follows the emission of alpha or beta particle.   Non ionizing radiation: Non-ionizing forms of radiation on living tissue have only recently been studied. Instead of producing charged ions when passing through matter, the electromagnetic radiation has sufficient energy to change only the rotational, vibration or electronic valence configurations of molecules and atoms. Nevertheless, different biological effects are observed for different types of non-ionizing radiation Radio waves: Radio waves whose wavelengths range from than 10^4m to 0.1m, are the result of charges accelerating through conducting wires. They are generated by such electronic devices as LC oscillators are used in radio and television communication system. Infrared rays: Infrared radiations have wavelength ranging from approximately 0.3m to 10^ -4m and also generated by the electronic devices. The infrared radiation energy absorbed by a substance as internal energy because the energy agitates the objects atoms, increasing their vibration or translational motion, which results temperature increases. Infrared radiation has practical and scientific application in many areas, including physical therapy, infrared radiation photography, and vibration spectroscopy. Ultraviolet radiation: Ultraviolet radiation cover wavelength ranging from approximately 4X10^4m to 6X10^-10m. The sun is an important source of ultraviolet radiation light, which is the main cause of sunburn. Sunscreen locations are transparent to visible light but greater percentage of UV light absorbed. Ultraviolet rays have also been implicated I the formation of cataracts. Most of the UV light from the sun is absorbed by ozone molecules in the earth upper atmosphere, in a layer called stratosphere. This ozone shield converts lethal high energy ultraviolet radiation to infrared radiation, which in turns warm the stratosphere. X-rays: X-rays have the range from approximately10^-8 to 10^-12m. The most common source of x-rays is stopping of high energy electrons upon the bombarding a metal target. X-rays are used as diagnostics tool in medicine and as the treatment for certain forms of cancer. Because x-rays can damage or destroy living tissue and organism, care must be taken avoid necessary exposure or over-exposure. X-rays are also used in the study of crystal structure because x-rays wavelengths are comparable to the atomic separation distance in solids. Electromagnetic radiation: The wave nature of electromagnetic radiation explains various phenomena like interference, diffraction and polarization. However, wave nature of electromagnetic radiation, could explain phenomena like photoelectric effect, Compton Effect. The cathode rays consist of negative charged particles called electrons which are the constituent of an atom and hence the constituent of matter. According to the concept of radiation example light waves radio waves, X-rays, microwaves etc. are assumed to carry energy in packets or bundles known as photons or quanta.    Biological effect of radiation: In biological effect of radiation, there are many dangerous effects of our health and body. Biological effects of radiation are typically can be divided into two categories. The first category consist of exposure to high doses of radiation over shots period of time producing acute or short term effects. The second category represents exposure to low doses of radiation over an extended period of time producing chronic or long term effects.   High dose (acute): high doses tend to kill cells, while low doses tend to damage or change them. High doses can kill so many cells that tissues and organs are damaged. This is turn may cause a rapid whole body response often called the acute radiation syndrome (ARS).   Low doses (chronic): low doses spread out over long periods of time dont cause an immediate problem to any body organ. The effects of low doses of radiation occur at the level of the cell, and the results may not be observed for many years.     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Although we tend to associate high doses of radiation with catastrophic events such as nuclear weapons explosions, there have been documented cases of individuals dying from exposures to high doses of radiation resulting from tragic events. High effects of radiation: high effects of radiation are skin burns, hair loss, sterility, cataracts. Effects of skin include (reddening like sunburn), dry (peeling), and moist (blistering). Skin effects are more likely to occur with exposure to low energy gamma, x-ray, or beta radiation. Most of the energy of the radiation deposit in the skin surface. The dose required for erythematic to occur is relatively high, in excess of 300 radiations. Blistering requires a dose in excess of 1,200 radiations. Hair loss, also called epilation, is similar to skin effects and can occur after acute doses of about 500 radiations. Sterility can be temporary or permanent in males, depending upon the doses. To produce permanent sterility, a dose in excess of 400 radiations is required to the reproductive organs. Cataracts (a clouding of the lens of the eye) appear to have a threshold about 200 radiations. Neutrons are especially effective in producing cataracts, because the eye has high water content, which is particularly effective in stopping neutrons.

Categories of effects of exposure to low doses of radiation: There are three general categories of effects resulting from exposure to low doses of radiation. These are: Genetic: the effect is suffered by the offspring of the individual exposed. Somatic: the effect is primarily suffered by the individual exposed. Since cancer is the primary result, it is sometimes called the carcinogenic effect. In-utero: some mistakenly consider this to be a genetic consequence of radiation exposure, because the effect, suffered by a developing is after birth. However, this is actually a special case of the somatic effect, since the embryo is the one to the radiation. Radiation risk: the approximate risks for the three principal effects to level of radiation are: In genetic effect, risk from 1 rem of radiation exposure to the reproductive organs approximately 50 to 1,000 times less than spontaneous risk for various anomalies. In somatic effect, for radiation induced cancer, the risk estimate is developing any type of cancer. However not all cancers are associated with exposure to radiation. The risk from dying from radiation induced cancer is about one half the risk of getting the cancer. In utero: Spontaneous risks of fetal abnormalities are about 5 to 30 times greater than risk of exposure to 1 rem radiation. However, the risk of child hood cancer from exposure in utero is about the same as the risk to adults exposed to radiation exposures. Linear no-threshold risk model: general consensus among experts is that some radiation dose by a linear, no threshold model. This model is accepted by the NRC since it appears to be most conservative. Linear: an increase in dose adults in a proportional increase in risk. No-threshold: any dose, no matter how small, produces some risk. The risk does not start at 0 because there is some risk of cancer, even with no occupational exposure. Exposure to radiation is guarantee of harm. However, because of the linear, no-threshold model, more exposure means more risk, and there is no dose of radiation so small that it will not have some effect. EFFECTS OF RADIATION ON CELLS Ionizing radiation absorbed by human tissue has enough energy to remove electrons from the atoms that make up molecules of the tissue. When the electron that was shared by the two atoms to form a molecular bond is dislodged by ionizing radiation, the bond is broken and thus, the molecule falls apart. This is a basic model for understanding radiation damage. When ionizing radiation interacts with cells, it may or may not strike a critical part of the cell. We consider the chromosomes to be the most critical part of the cell since they contain the genetic information and instructions required for the cell to perform its function and to make copies of it for reproduction purposes. Also, there are very effective repair mechanisms at work constantly which repair cellular damage including chromosome damage. Uses of radiation: Nuclear physics application are extremely widespread in manufacturing, medicine in biology, we present a few of these application and underlying theories supporting them. Tracing: Radioactive tracers are used to track chemicals participating in various reactions. One of the most valuable uses of radioactive tracers in medicine. For example, iodine, a nutrient needed by the human body, is obtained largely through intake of iodized salt and sea food. Radiation therapy: Radiation causes much damage to rapidly dividing cells. Therefore, it is useful in cancer treatment because tumor cells divide extremely rapidly. Several mechanisms can be used to deliver radiation to a tumor. In some cases, a narrow beam of x-ray or radiation from a source such as 60co is used. In other situation, thin radioactive needles called seeds are implanted in the cancerous tissue. The radioactive isotope 131I is used to treat cancer of the thyroid.   Black body radiation: An object at any temperature emits electromagnetic waves in the form of thermal radiation from its surface. The characteristics of this radiation depend on the temperature and properties of the objects surface. Thermal radiation originates from accelerated charged particles in the atoms near the surface of the object; those charged particles emit radiation much as small antennas do. The thermally radiation agitated particles can have a distribution of energies, which accounts for the continuous spectrum of radiation emitted by the object. The basic problem was in understanding the observed distribution of wavelengths in the radiation emitted by a black body. A black body is an ideal system that absorbs all radiation incidents on it. The electromagnetic radiation emitted by the black body is called blackbody radiation. Radiation damage: Radiation damage means that electromagnetic is all around in the form of radio waves, microwaves, light waves so on. The degree and type of damage depend on several factors, including the type and energy of the radiation and properties of the matter. Radiation damage in biological organism is primarily due to ionization effects in cells. A cells normal operation may be disrupted when highly reactive ions are formed as the result of ionizing radiation. Large those of radiation are especially dangerous because damage to a great number of molecules in a cell may cause to die. In biological systems, it is common to separate radiation damage in two categories: somatic damage and genetic damage. Somatic damage is that associated with any body cell except the reproductive cells. Somatic damage can lead to cancer or can seriously alter the characteristics of specific organism. Genetic damage affects only reproductive cells. Damage to the genes in reproductive cells can lead to defective cells. It is important to be the aware of the effect of diagnostics treatments, such as X-rays and other forms of radiation exposure, and to balance the significant benefits of treatment with the damaging effects. Damage caused by the radiation also depends on the radiations penetrating power. Alpha particles cause extensive damage, but penetrate only to shallow depth in a material due to strength interaction with other charged particles. Neutrons do not interact via the electric force and hence penetrate deeper, causing significant damage. Gamma rays are high energy photons that can cause serve damage, but often pass through matter without interactions. For example- a given dose of alpha particle causes about ten times more biological damage produced by radiation than equal dose of x-rays. The RBE (relative biological effectiveness) factor for a given type of radiation is the number of rads of x-radiation or gamma radiation that produces the same biological damage as 1-rad of the radiation is being used. Radiation detectors: Particles passing through matter interact with the matter in several ways. The particles can, for example- ionize atoms, scatter from atoms, or be absorbed by atoms. Radiation detectors exploit these interactions to allow a measurement of the particles energy, momentum, or change and sometimes the very existence of the particle if it is otherwise difficult to detect. Various devices have been developed for detecting radiation. These devices are used for a variety of purposes, including medical diagnoses, radioactive dating measurement, measuring back ground radiation, and measuring the mass, energy, and momentum of particles is created in high-energy nuclear reaction.   EFFECT OF RADIATION ON HUMANS A very small amount of ionizing radiation could trigger cancer in the long term even though it may take decades for the cancer to appear. Ionizing radiation (x-rays, radon gas, radioactive material) can cause leukemia and thyroid cancer. There is no doubt that radiation can cause cancer, but there still is a question of what level of radiation it takes to cause cancer. Rapidly dividing cells are more susceptible to radiation damage. Examples of radiosensitive cells are blood forming cells (bone marrow), intestinal lining, hair follicles and fetuses. Hence, these develop cancer first. If a person is exposed to radiation, especially high dose, there are predictable changes in our body that can be measured. The number of blood cells, the frequency of chromosome aberrations in the blood cells and the amount of radioactive material in urine, are examples of biomarkers that can indicate if one is exposured high dose. If you do not have early biological changes indicated by these measurements the radiation exposure will not pose an immediate threat to you. Radiation poisoning Radiation poisoning, radiation sickness or a creeping dose, is a form of damage to organ tissue caused by excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long term exposure. The clinical name for radiation sickness is acute radiation syndrome as described by the CDC A chronic radiation syndrome does exist but is very uncommon; this has been observed among workers in early radium source production sites and in the early days of the Soviet nuclear program. A short exposure can result in acute radiation syndrome; chronic radiation syndrome requires a prolonged high level of exposure. Radiation exposure can also increase the probability of developing some other diseases, mainly cancer tumors, and genetic damage. These are referred to as the stochastic effects of radiation, and are not included in the term radiation. Radiation Exposure Radiation is energy that travels in the form of waves or high-speed particles. It occurs naturally in sunlight and sound waves. Man-made radiation is used in X-rays nuclear weapons, nuclear power plants and cancer treatment. If you are exposed to small amounts of radiation over a long time, it raises your risk of cancer. It can also cause mutations in your genes, which you could pass on to any children you have after the exposure. A lot of radiation over a short period, such as from a radiation emergency can cause burns or radiation sickness. Symptoms of radiation sickness include nausea, weakness, hair loss, skin burns and reduced organ function. If the exposure is large enough, it can cause premature aging or even death.

Presenting People in Two Scavengers in a Truck, Two Beautiful People in

Presenting People in Two Scavengers in a Truck, Two Beautiful People in a Mercedes, and Island Man In this essay I will compare the ways in which the poets present people in â€Å"Two Scavengers in a truck, two beautiful people in a Mercedes† by Lawrence Ferlinghetti and â€Å"Island Man† by Grace Nichols. In this essay I will look at the shape, structure, poetic devices and language in both poems. Firstly I will examine what the two poems are about and the ways how both poets portray the people in the poems. The poem â€Å"Two Scavengers in a truck, two beautiful people in a Mercedes† is about a coincidence meeting of the two working class scavengers and a beautiful, rich couple in Mercedes. This poem was set in America and was aimed to show that there is class division and was commenting on American society. In this poem there is a huge contrast between rich and poor. I know this because the description of the two scavengers and the rich couple shows us the inequality that the two classes have. The poem is not set in stanzas but can be divided into 5 stages. It is more s...

Opening Paragraphs for a “Heroes” Essay

A hero is defined as a man of distinguished courage or ability, admired for his brave deeds and noble qualities. People desire someone to admire at certain times to help lead and guide them. The many paths of life help to shape heroes. They can be found anywhere from a police officer to a football player. Everyday people will look for them for inspiration for themselves. Heroes push us to strive for more out of life while also helping us through tough times.Heroes are very important to our way of life and shape our view of life. People need heroes for three reasons: devastation, tragedy and losses. The devastation of an event can cause a person to need a hero, someone to look to for answers. When a person encounters a tragedy, they also try to look to someone as a solution for their problems. People encounter losses everyday and each day they seek guidance. In each of the above situations, persons yearn for a hero. Certain events in our life can have profound effects on us.A lot of t ime, it is from devastating events. Devastating events can be extremely disappointing and heart wrenching. Battling our way out of these events can truly show the heart of a person. Heroes shine in times such as these. They battle through the hardest of adversity and win. These adversities can range from the simple to the momentous. When devastation occurs, persons are in a hole, looking for a way out and find their shining hero at the end to help save them.This is where the heroes come in making for a great ending and promising future. Heroes in this situation are made through experience and knowledge of how hard such devastation can be. People then look to them to see how they got through it and can follow their example. When a disappointment occurs, persons need to know that there is hope, hope knowing that someone else overcame the same obstacle. We all encounter devastations but tragedies are encountered less often.

Michael Henchard’s life is a series Essay

Michael Henchard’s life is a series of terrible disasters, which leads to self destruction. However, deciding whether Michael Henchard is responsible for his own downfall and to what extent is something which needs a lot of deliberation before getting an answer. There are different factors which need to be looked at before deciding this, such as whether it was Henchard’s fault, or whether he could have stopped the disaster from happening. The only way to determine whether or not Henchard is totally responsible for his own downfall is to look at each disaster which occurs in the novel and then see whether he could have prevented it or not. Starting directly from the beginning, the novel begins with Michael Henchard travelling with his wife and daughter and then stopping at a furmity tent for some food. Michael straight away decided that he wanted some rum in his furmity. â€Å"He winked to her, and passed up his basin in reply to her nod; when she took a bottle from under the table, slily measured out a quantity of its contents, and tipped the same into the man’s furmity. The liquor poured in was rum. † He soon got drunk after several helpings of it and when his wife tried to quieten him a little. He then began to ramble about how better off he would be without her. â€Å"I married at eighteen, like the fool that I was; and this is the consequence o’t. † It is clear to the audience that Henchard is a rude and careless character. Henchard’s attitude and behaviour is influenced by alcohol, and it appears to the audience that his wife, Susan is aware of this. â€Å"†¦ his wife, who seemed accustomed to such remarks, acted as if she did not hear them†¦ † The scene is set for a foreboding novel when Hardy expresses his feelings about nature and mankind in the first part of the novel. He compares nature and mankind. â€Å"In contrast with the harshness of the act just ended within the tent was the sight of several horses crossing necks and rubbing each other lovingly, as they waited in patience to be harnessed†¦ † After Michael spending his evening drinking rum, he began auctioning his wife to anybody who would buy her. A sailor offered Michael Henchard 5 guineas for both hi wife and daughter. Michael would not sell them for any less. Susan gave Henchard one last chance to say he didn’t mean it before she left with the sailor as it wasn’t a joke no more. â€Å"A joke? Of course it is not a joke! † Shouted her husband. With this his wife and daughter left with the successful bidder. Michael Henchard losing his wife and child was the first disaster. This disaster was without a doubt Michael’s fault. He had decided to have rum with his furmity, even though he had had it before, knowing that he makes him drunk, and he knew he had tried to sell his wife before. He should have known not to have too much, if any liquor, and because he chose to do so in the knowledge that he has a bit of a drinking problem, this makes the whole disaster hid fault. I do not think that any blame can be passed onto his wife. Susan felt the contempt that Michael had for her. Henchard shows he has integrity once sober, when he later regrets selling his wife and daughter and goes to search for her. â€Å"Well I must walk about till I find her†¦ † This shows a positive side to Henchard, for taking the time to recover the mistake he made. He also made an oath not to drink for 21 years, due to his hideous behaviour the previous night. In contrast to this, he later blames Susan for his atrocious attitude and behaviour and appears very angry at her. â€Å"†¦ seize her, why didn’t she know better than being me into this disgrace! † He roared out. † In the next part of the novel, Susan finds Henchard as a successful businessman as mayor of a small town called Castorbridge. â€Å"Mr. Henchard- now habited no longer as a great personage, but as a thriving business man. † Henchard has worked hard and had a lot of determination to get to where he is now. He needs to continue being successful and hard working in order to prevent his own downfall, as Henchard has much more to lose now. Henchard meets a Scottish man called Donald Farfrae by accident but takes a liking to him and employs him in order to increase his wealth. Farfrae has inventive machines which are useful to trade. â€Å"†¦ it is true that I am in the corn trade†¦ I have some inventions useful to the trade†¦ † Farfrae appears to be a helpful, kind, gentleman, who is willing to help and is a good citizen. Hardy describes how the town of Castorbridge have already taken a liking to Farfrae. The audience can view Henchard’s jealousy of Farfrae. â€Å"By this time he had completely taken possession of the hearts of the Three Mariner’s inmates. † After 19 years ‘Henchard’s daughter’, Elizabeth-Jane returns with a message from his wife Susan. Henchard is over-whelmed to see EJ again. He shows her around his beautiful home and makes her feel very welcome. He is highly surprised to hear that his wife whom he had sold many years ago remains alive. â€Å"Oh— Susan is— still alive? † He asked with difficulty. By Hardy expressing how Henchard speaks about Susan reflects his true feelings for her. Henchard doesn’t necessarily love Susan still, but he does show contempt for her towards EJ. Henchard informs Farfrae of his disastrous past when he sold his wife and child EJ. â€Å"Well, I lost my wife nineteen years ago or so -by my own fault†¦ † By Henchard admitting to doing something wrong shows he has integrity again. By Henchard being completely honest with his business partner, the audience see the positive side to him come out again. Henchard’s downfall continues from his relationship with Farfrae. Hardy describes the liking Henchard has for Farfrae. This is used to make Henchard’s downfall look bigger than if Henchard wasn’t so involved and close to Farfrae. Henchard and Susan are not lovers anymore and Susan meets him at the ‘ring’, an amphitheatre near Castorbridge which Hardy describes as,†Ã¢â‚¬ ¦ seldom had place in the amphitheatre, that of happy lovers. † Even though Susan and Henchard are not close anymore, Henchard shows sensitivity towards Susan and begins their conversation in a peculiar way. â€Å"I don’t drink anymore. † This is Henchard wanting to prove a point to Susan that he regrets what he did, by telling her that he now feels responsible for his actions shows a positive side to Henchard. Susan and EJ see a lot more of Henchard and after a while EJ becomes closer to Michael and spends more time with him than she does her mother. As the bond grows between the two, Henchard requests for EJ’s name to be changed to Miss. Henchard in its place of Miss. Newson. â€Å"Now, Susan, I want to have her called Miss. Henchard- not Miss. Newson†¦ it is her legal name-so it may as well be made her usual name- I don’t like t’other name at all for my own flesh and blood†¦. She won’t object. † â€Å"No. O no. But-† â€Å"Well, then, I shall do it,† said he, peremptorily. The audience see a stubborn and self-centred side to Michael here. In contrast to this the audience can also see how much Henchard wants EJ to become part of his family again by name. This again shows that he is sorry for what he done. Michael seems rather pushy towards Susan. Susan is slightly hesitant about the whole situation. Taking a situation like this upon himself, without his wife actually agreeing is very selfish of Henchard. The audience notices Susan’s hesitance and begin to sense an explanation for this. Hardy includes another character Abel Whittle in order to illustrate the variation in character between Henchard and Farfrae. Abel is employed by Henchard and when Abel is late Henchard uses an insensitive approach on Whittle. Quite the reverse to this Farfrae shows a more kind and gentle approach towards him. This sparks jealousy of Henchard on Farfrae. A sense of disruption in their relationship occurs and the audience can see the beginning of Henchard’s downfall. Henchard also becomes jealous of Farfrae when he begins to bond with EJ. Henchard doesn’t want to run the risk of losing EJ therefore dispenses with Farfrae. â€Å"Mr. Farfrae’s time as my manager is drawing to a close- isn’t it Farfrae? † He did this because he loves EJ, but he also wants to keep his good name and does not wish for Farfrae to take over everything. Hardy is clever, in the way he creates the characters Henchard and Farfrae. He makes Henchard’s character the complete opposite to that of Farfrae. This gives the audience a great understanding and knowledge of each character; therefore they’re able to predict what will occur after each turning point to each character. Henchard realises he is in yet another disaster. Michael had not too long before his wife and daughter had found him, spent the night with a woman called Lucetta. He had then promised to marry her so she can keep her virtue. He did this thinking that Susan and EJ had died. This of course means he cannot marry Lucetta. Susan becomes to unwell to leave her bed, therefore Henchard and EJ are expected to look after her. In the mean time Lucetta tells Henchard she wants her letters back, and that she wishes to meet him at the antelope hotel. â€Å"†¦ I shall be in the coach, which changes horses at the antelope hotel at half past five on Wednesday evening; I shall be wearing a Paisley shawl with a red centre, and this may be easily found. I should prefer this plan of receiving them to having them send. – I remain still, yours ever. ‘LUCETTA’ â€Å". Hardy includes a lot of specific description in Lucetta’s letter, which shows a strong character to Lucetta. Thomas Hardy has a strong point of putting across the personalities of characters to the audience. Michael is in a bit of a tricky situation here, with Susan too ill to get out of bed, and Lucetta requesting to see him. Henchard has put himself in this mess in the first place, by assuming that Susan and EJ were dead. On the other hand Henchard shows positive again by being honest with Lucetta, informing her of the unexpected arrival of his ‘who he thought was dead’ wife and child. When the traumatic death of Mrs. Henchard occurs, the lonely sad life of Michael Henchard appears. The only person he now cares about and has got left is Elizabeth Jane. EJ has lost her mother and Henchard wants EJ to know who her father is. EJ is originally shocked at what she has just heard but then settles nicely and begins called him dad. The next catastrophe which happens, Henchard walks straight into himself. Susan left a letter in an envelope for Henchard stating â€Å"Not to be opened until the wedding of EJ†. The audience immediately know that Henchard will open the letter by the anxious character which Hardy has created. EJ isn’t really Henchard’s daughter. Henchard feels that fate is against him and he begins to feel separated from EJ. Without Henchard’s eagerness and self-concerned attitude towards everything, Henchard would be able to continue his happy life with his daughter, oblivious to the fact that she isn’t his own. Hardy’s efforts to put across the personality of Michael Henchard at the beginning of the novel are very successful. Throughout the novel Henchard’s downfall has just increased by the day. The language used at the beginning of the novel is exceptionally descriptive. First impressions of Henchard are positive from reading the first page. The negative side begins to show when he reaches the furmity tent. By chapter 31 Hardy shows that Henchard has sunk socially and financially. He has to go and live with Joshua Jopp and refuses to see anyone. â€Å"Socially he had received a startling fillip downwards; and, having already lost commercial buoyancy from rash transactions, the velocity of his descent in both aspects became accelerated every hour. † Farfrae and EJ decide to get married. Henchard shows integrity by attending but EJ just can’t forgive Henchard for what he did and walks away form him. He bought a goldfinch as a wedding present, which Hardy uses as a symbol of Henchard’s life. Some people may have different opinions on why Henchard went downhill. Some people may put it down to fate. Others may think that Henchard is entirely responsible for all that happened. Hardy leaves this decision quite widely open. Henchard’s character has an extreme effect on other people and how their lives are lived, especially EJ’s.

Program Development and Evaluation Essay

Early Childhood Education focuses on the education, language, culture, development and care of young children. As a profession, Early Childhood Education has emerged as one of the major vehicles for child-advocacy in the provision of accessible, high-quality child care and pre-school education. Child care, in this society of increasingly busy working couples, is an important service in the community. Whether it is called child care, kindergarten, preschool, a developmental learning center, a child development center, or one of many other names, they are all providing the important service of caring for our precious children. The increased demand for early childhood education services is partly due to the increased recognition of the crucial importance of experiences during the earliest years of life. Children’s experiences during early childhood not only influence their later functioning in school but can have effects throughout life. For example, current research demonstrates the early and lasting effects of children’s environments and experiences on brain development and cognition (Chugani, Phelps, & Mazziotta, 1987). Positive, supportive relationships, important during the earliest years of life, appear essential not only for cognitive development but also for healthy emotional development and social attachment (Stern, 1985). The preschool years are an optimum time for development of fundamental motor skills, language development (Dyson & Genishi, 1993), and other key foundational aspects of development that have lifelong implications. In Australia, early childhood educational programs cover a 0-8 years age range. In the state of New South Wales, Kindergarten is the first year of compulsory schooling thus it is governed by the NSW Department of Education and Training and the curriculum content governed by the NSW Board of studies. Child care, on the other hand refers to the care of infants (ages 0-5) by other people during specific periods when the parents are at work. With this set-up, different programming methods are employed. The difference between child care and kindergarten is that kindergarten is an educational experience while child care tends to be care giving so that both parents can work. Good child care programs offer experienced, well-educated teachers who promote children’s cognitive and social development. Kindergarten programs, on the other hand, have set programming standards that are based on the curriculum content governed by the NSW Board of studies. However, in the light that infants and up to kindergarten age belong to the early childhood category, it is best that programming should be the same. It should be able to provide the necessary resources to ensure that every student is offered a high-quality learning environment that prepares a child for further schooling. The purpose of this paper is to present the basis that programming for all early childhood educational programs in NSW should, for the most part, be the same regardless of the setting in which the program exists. Main Body Programming is the process of setting an order and time for planned events or activities. It is the designing, scheduling, or planning of a program. In a formal education setting, syllabus is prepared to outline the set of activities or programs. In NSW schools, teaching and learning programs and the assessing and reporting of student achievement relate directly to the learning outcomes and curriculum content provided in the NSW Board of Studies K-6 syllabuses. As clearly stated in the K-6, programming for kindergarten falls under this curriculum. These syllabuses are grouped into six key learning areas (KLAs). Creative and Practical Arts English Human Society and Its Environment Mathematics Personal Development, Health and Physical Education Science and Technology (Retrived Aug. 31,2006 from http://www. curriculumsupport. education. nsw. gov. au/primary/index. htm) The Board of Studies develops a syllabus for each of the learning areas. Along with a defined aim, each syllabus has a set of objectives and outcomes, expressed in terms of knowledge and understandings, skills, values and attitudes. On the other hand, mostly day care in NSW are managed by community organizations, local councils or private operators. These day care and other children’s services are licensed by the Department of Community Services. NSW Department of Education and Training employs an early childhood trained teacher and a teacher’s aide in each preschool class. Teachers plan an educational program, which nurtures each child’s self esteem, well being and development. The preschool or day care program is designed to stimulate children’s thinking, communicating, investigating, exploring and problem solving skills. Children are encouraged to join in physical activities and to develop good health and safety habits. The program includes play based activities that help children learn how to interact positively with other children and to recognize and accept their own feelings and those of others. The program also supports the development of early language, literacy and numerical skills. In terms of child upbringing however, it is always advocated that child care is inherently inferior to parental care. However, independent studies suggest that good child care for non-infants is not harmful. In some cases, good child care can provide different experiences than parental care does, especially when children reach two and are ready to interact with other children. A study appearing in Child Development in July/August 2003 found that the amount of time spent in child care before four-and-a-half tended to correspond with the child’s tendency to be less likely to get along with others, to be disobedient, and to be aggressive, although still within the normal. On the other hand, bad child care puts the children at physical, emotional and attachment risk. As a matter of social policy, child care should also be regulated by the government so as to ensure quality early childhood education. A good early childhood education program should instruct children in different skill areas that they would need in further schooling. Such skill areas include learning to read, to do math, to progress in science, and to understand the world and how it works. Through early childhood education programs, children are able to become familiar with books, words, language use, numbers and problem solving, as well as important social skills (paying attention in class and peer relationships). Through all these activities, teachers should create positive relationships through warm, sensitive, and responsive care, which will help children feel valued and gain more from their learning experiences. Children need positive relationships so that they feel comfortable and learn how to cooperate with others. This is where skilled early childhood educators should come in. Early childhood care and kindergarten education need teachers who are educated enough to handle young children from infancy through age six. Relationships between teachers and families are also important, and help build environments that nurture children’s growth and development. Children observe the interactions between caregivers and their parents, and what they observe in these interactions is used to build their own relationship with these new adults in their lives. This is a process called social referencing (Hutchins & Sims, 1999). There are many ways that quality early childhood programs build relationships with children and among teachers and adults. In visiting a program, how teachers interact with the children fostering positive relationships is clearly seen. Classrooms are welcoming to all children, and children are encouraged to join the group. Teachers communicate with children in a warm manner, including laughing and showing affection, and responding to their needs. Teachers use a gentle tone of voice with children, and bend down to speak with them at eye level. Teachers provide a balance of group activities and one-on-one activities, to encourage children to develop both group and individual relationships. Children in turn have opportunities to play and interact with other children, who help them build friendships and develop social skills, such as working together and taking turns. In good child care program, infants get individual attention from teachers, who communicate with smiles and other nonverbal behavior, and also talk with them, so that infants start to recognize and understand words. Quality early childhood programs foster positive relationships – among the children, between children and adults, and among teachers and families – to help children get a great start on learning. In view of the need to acquire good educators, the development of professional standards for teachers has grown in importance in the field of education in Australia and overseas. At the national level, development of the National Framework for Professional Standards for Teaching is a key initiative. The Competency Framework for Teachers was created and standards were developed by national teaching associations for English, Mathematics and Science. This Framework is the product of a comprehensive consultation process involving teachers, professional associations, tertiary institutions, the Australian Education Union and other key stakeholders. The Competency Framework for Teachers articulates the complex nature of teaching by describing three professional elements of teachers’ work: attributes, practice and knowledge. These elements work in an interrelated way as they are put into practice in classrooms. Early childhood professionals working in diverse situations and resources are responsible for implementing practices that are developmentally appropriate for the children they serve. These teachers have an ethical responsibility to practice, to the best of their ability, according to the standards of their profession. They are required to acquire the knowledge and practical skills needed to practice through college-level specialized preparation in early childhood education/child development. Moreover, aside from teachers, administrators of early childhood programs are also encouraged to acquire necessary skills in maintaining good practices in their field. In addition to management and supervision skills, administrators have appropriate professional qualifications, including training specific to the education and development of young children, and they provide teachers time and opportunities to work collaboratively with colleagues and parents. Providing appropriate curriculums or programs to meet the desires of individual children who learn at different rates and in different ways needs much skill and knowledge from the educator or teacher. In planning the everyday program a wide range of teaching strategies will be needed that involve individual, and large and small group activities. Not simply should the provision offer children opportunities for a broad range of creative and ingenious play activities, but there must be sufficient time and space to permit children to develop and extend their play, sometimes alone and at times in the company of other children or an adult. Programs have changed in response to social, economic, and political forces. However, these changes have not always taken into account the basic developmental needs of young children, which have remained constant. Programs should be tailored to meet the needs of children, rather than expecting children to adjust to the demands of a specific program. In the Hyson, Hirsh-Pasek, and Rescorla study (1990), pre-school children enrolled in child-initiated programs displayed lower levels of test anxiety than children enrolled in academic programs, regardless of parental preferences for classroom approaches. In the second study (Burts et al. , 1990), children in inappropriate classrooms exhibited more total stress behaviors throughout the day and more stress behaviors during group times and workbook/worksheet activities. Early childhood teaching is simply and completely about children and their well being. The tenet that each child is unique is basic in early childhood philosophy. It is very important therefore that early childhood educators should plan flexible programs that accommodate individual growth. Additionally, an early childhood perspective acknowledges the importance of providing children with opportunities to interact, understand and cooperate in groups (Day & Drake, 1986). In view of these arguments, the principle of programming in the framework of the KLA and in the context of a formal academic education should not yet be employed in the early childhood education, in particular, kindergarten class. The Curriculum for early childhood education must be subjected to vigilant evaluation. The program should see children as active learners, supporting them to become self-determining, being problem solvers and decision makers. It should not be a stiff program but offers a framework for children’s learning. Though it has much in common with usual nursery practice, it places greater accountability upon children for planning and executing their own actions. Working on an idea of the plan, do and review, the environment is arranged so that it optimizes children’s learning, using key experiences to examine and plan for the individual needs of children, for instance adult-child communication strategies, partnership with parents, observation and record keeping. The key experiences embedded concept of active learning are: †¢ Using language such as depicting objects, events and relations; †¢ Active learning such as controlling, transforming and mixing materials; †¢ Characterizing ideas and experiences such as role playing, pretending; †¢ Developing rational reasoning such as learning to label, match and sort objects; †¢ Understanding time and space such as evoking and anticipating events, learning to get things in the classroom. (Curtis, A. , 1999) These key experiences not only offer the framework for planning and evaluating activities but also facilitate the staff to guide children from one learning incident to another. They suggest questions to put to the children and facilitate staff to assess children’s development and offer a basis for discussion with the parents. To achieve individually appropriate programs for young children, early childhood teachers must work in partnership with families and communicate regularly with the children’s parents. During early childhood, children are largely dependent on their families for identity, security, care, and a general sense of well being. Communication between families and teachers helps build mutual understanding and guidance, and provides greater consistency for children. Joint planning between families and teachers facilitates major socialization processes, such as toilet learning, developing peer relationships, and entering school. Mutual sharing of information and insights about the individual child’s needs and developmental strides help both the family and the program. Regular communication and understanding about child development form a basis for mutual problem solving about concerns regarding behavior and growth. Teachers seek information from parents about individual children. Teachers promote mutual respect by recognizing and acknowledging different points of view to help minimize confusion for children. The positive attributes of parent/teacher relationships are relatively easy to develop when teachers and parents have the same backgrounds, speak the same languages, share values and goals for children, and, in general, like one another. Parents are also more likely to relate to their children’s caregivers and teachers in positive ways, and are aware of the conditions under which the staff is working. For both parents and teachers, continuity of the children’s educational experience is critical to their development. Such continuity results from communication both horizontally, as children change programs within a given year, and vertically, as children move on to other settings. As such, programming of early childhood education should be based more on creative learning and not on rigid academic programs and they should be the same from child care to kindergarten. Lastly, the community and the society at large also have a stake in the quality of early childhood programs. Early childhood education entails an informed community willing to act upon the idea that high quality early education is necessary for future generations (Pascall, C. and Bertram, T. , 1997). When early childhood programs succeed in getting children off to a good start, families, schools, and communities will be strengthened. Children will grow up to be responsible, law abiding and productive citizens who will contribute to the country’s progress. In this sense, posterity itself eventually reaps the benefits of high-quality early educational experiences. Conclusion Curriculums and programs are frequently viewed only in terms of the product or the content to be taught. It is far more encompassing than this, though. The curriculum should also be considered in terms of the processes linking to learning and teaching, the objectives that both teachers and learners hold, the contradictory social and cultural experiences’ learners and teachers bring, and the realities that occur from classroom interactions and situations. In early childhood education, set programming standards that are based on academic formal structure and being practiced in classrooms should not be employed. Teaching and learning programs and the assessing and reporting of student achievement that relates directly to the learning outcomes and curriculum content provided in the NSW Board of Studies K-6 syllabuses is not yet applicable and favorable for very young minds. Instead, programs and teaching practices in early childhood settings should be more responsive to the needs and interests of the children. Programs should include a plan of activities that matches the children’s needs and promotes their independence. The plan should contain activities and exercises that help children to develop social, motor, language, and thinking skills. Programs should also provide a variety of experiences designed to encourage exploration and problem-solving, and an awareness of how diverse the world is beyond the home. Daily morning schedule for kindergarten as well as child care should be very similar. The only difference between the two settings is that kindergarten school children tend to arrive all at once while children arrive at child care centers according to their parents’ work schedules. Early childhood education in both kindergarten and child care settings must actively work to provide learning in a nurturing environment that matches the needs of the children. Parents also have active role in this endeavor. Children learn much from the adults around them, not simply from the planned learning opportunities but also from the customs and routines of daily living. The attitudes of the adults and other children and the shared relationships that are formed are as vital to children’s development as the activities in which they are engaged. The goals of the entire child care community, then, must be to encourage and support early childhood professionals to raise standards in our young children’s education. In providing an effective and successful program for early childhood education, our society and our country will reap the rewards of raising disciplined and productive children who will contribute greatly in our communities.
