What is Economics an Example of the Topic Economics Essays by

What is Economics? Economics refers to a social science that studies how various goods and services are produced, allocated and consumed (Mofid, 27). It can also be the study of the scarce economic resources and how they are used to satisfy human needs. There are two main branches of economics; microeconomics and macroeconomics. Microeconomics is concerned with how individuals make decisions and how those decisions affect supply and price of goods and services in the economy. Microeconomics in a general point of view is all about making choices, scarcity and how the scarce resources satisfy the needs of an individual (Mofid, 28). Macroeconomics on the other hand gives an economy a wide point of view as it provides solutions to economic problems like unemployment, inflation and even taxation policies. Need essay sample on "What is Economics?" topic? We will write a custom essay sample specifically for you Proceed One of the reasons why people study economics is to understand how individuals and even governments try to use the scarce resources to satisfy the unlimited and insatiable human needs. Economics is also studied to help individuals understand the production concepts. This is the concept that outlines the process of production from the raw materials stage to the products in the market. The study of economics has helped many know what to sell and what to buy at what price to avoid losses. Companies and other business enterprises uses the business knowledge to know that one objective of business is to maximize the profits. The study of economics has really helped many governments and states to solve many national problems like unemployment, inflation and even the taxation policies have been understood well by the economic education. Generally, economics is a very vital subject to those who study it and currently it has been included in the curriculum of many colleges and universities. It has helped in solving many microeconomic and macroeconomic issues that surround us. The question of production which is critical in the development of states is well answered in economics. The appropriate allocation of the increasingly scarce resources determines this economic development. Works cited: FunQA.com. What are economic activities? FUnQA.com, 2007-2009.

A Literary Review Dealing with Nursing as a Profession Essays

A Literary Review Dealing with Nursing as a Profession Essays A Literary Review Dealing with Nursing as a Profession Paper A Literary Review Dealing with Nursing as a Profession Paper The purpose of this paper is to present a literary review dealing with nursing as a profession which pertains to health care. There are also five recent scholarly journals that have been specifically chosen, to complete a detailed annotated bibliography. Mullane, M. (2000). A Glance Back in time: future, higher education, and professional development. Nursing Forum, 35 (4), 41-45. Throughout this article the author presented information that demonstrated the concern of the future of nursing. She compares the past and present, stating that we are at a junction which is demanding a choice of direction in which way nursing may go. The direction of nursing is unknown especially concerning nursing education. The future of nursing depends upon many different things, it is affected by progress in health care and by it? s past. The scientific social forces that surround it today enforce it. This all rests upon nurses themselves and is shaped by administrators of our health services and by practicing physicians. The author feels that in the education field of nursing apprenticeship has advantage over other forms of education. She has acknowledged that the graduate is an expert in techniques, however by reinstating the apprenticeship system that was used in the past we will create a greater nurse. After reviewing the literature it is important to assess the level of expertise of the author. Mullane (2000), at the time of publication, had her RN, PhD, was Annotated Bibliography: 3 Dean of the College of Nursing at the University of Iowa in Iowa City. This journal was also one of many journal articles she has written. After completing the review of this research article I was able to determine the purpose of this article was to inform individuals that nursing is at a point where changes need to be made. With all the advancements we have we are able to make these changes to better the nursing profession. The author also suggests that we can return to the way things used to be, with more hands on. The article provides sufficient background information with specific dates and events. The intended audience of this paper was healthcare professionals, nurses, teachers, general public and colleagues. The author painted a picture of a nursing student who graduates out of University is an unprepared nurse not mentally but with hands-on tasks. The only sort of supplementary data this article offered was one other source from the Nursing Forum. Overall, this article is useful for nurses and healthcare professions who are interested in looking into the future of nursing. Annotated Bibliography: 4 Cardillo, D. (2001). Nursing, promote thyself: public relations, professional development and guidelines. Journal of Nursing Care Quality, 14 (2), 40-49. The author suggested that nurses have been working quietly in the background, with little recognition. Therefore, it is time for nurses to come through and self-promote. The author feels it is vital to the survival and the long-term success of the profession. The article suggests ways to promote yourself as a nurse such as: taking stock of your strengths and assets, become active in nursing associations, when winning an award make it known, attend work-related social events and volunteer on committees. In order to determine the credibility of the article the credentials of the author must be assessed. Cardillo had achieved her RN, BS, is president of Cardillo Associates Professional Development Seminars in Wall, N. J. , also a keynote speaker, author and consultant. I am extremely confident the author is capable due to her credentials and the amount of experience she has accumulated throughout her years of being a nurse. Throughout this article the fundamental purpose is self-promotion in health care and how to accomplish it. This article however, does not deal with a great deal of background information, and does not use any other sources. The scope of the article is towards nurses in general. All the points throughout the article Annotated Bibliography: 5 pertain to promoting themselves. The general usefulness of this work for other individuals who are researching this topic is not extremely important, because they are more self-promotion tips for nursing staff. Annotated Bibliography: 6 Wyatt, J. S. (2001). How do you spell nursing? With a capital ? C?! : Nurses and caregivers. Pediatric Nursing Journal, 27 (1), 103-109. Throughout this article the author explains how nurses have remained dedicated caregivers, however the complexity of caring has changed. She discusses how nurses can strengthen the valuable foundation of caring and make it a greater visible part of the nursing profession. The article states that since the world has exploded with new scientific discoveries, theories and technologies it over powers what health care is all about, caring. She acknowledges the shortage of nursing staff but for many nurses patient care has become a game of ? beat the clock?. They want to see how many procedures, how fast and how efficient. When you look at the task you completed you realize the main goal of patient caring is gone. In order to determine if the author is an expert on the topic her credentials must be discussed. Wyatt has her PhD, RN, CRP and has over thirty years of experience in nursing. Her clinical nursing experience includes practice in intensive care units, community health settings, and as a primary care nurse practitioner and nurse researcher. She also has over twenty years of experience in undergraduate and graduate nursing education and now serves as the Executive Director of the National Certification Board of Pediatric Nurse Practitioners and Nurses, she also holds the leading certification organization for pediatric nursing. Annotated Bibliography: 7 I believe that this authors credentials are extremely impressive making her an expert in the field of nursing and caring. The fundamental purpose of this article is to show nurses what nursing is really about, caring. I t allows nurses to take a step back from their job and realize that maybe they have not been treating patients the way they should be treating them. This article provides a great deal of backgrounds information. It includes many other articles pertaining to caring also providing statistics. The main audience of this article is nursing staff and caregivers. It is geared towards helping them increase there caring towards patients. The general usefulness of this article for an individual who is doing an essay on the selected topic is by reading the article it makes you realize how the profession has changed over the years. It shows what can be done about the mistakes that the healthcare individuals are making and what nursing is really about. Annotated Bibliography: 8 Mee, C. L. (2001). Magic Moments: Nursing Careers. American Journal of Nursing, 31 (8), 6-10. The author presented her ideas on nursing and why she chose to become a nurse. She states the important aspects of a nursing career and the benefits on becoming a nurse. She has many specific ideas on what a nursing career contains she mentioned such aspects as holding patients hands, talking with them, making them smile, being kind, intelligent, making the frail feel sick, having great strength and control. Most importantly being aware that you could contribute to someone else wanting to be a nurse. In order to determine the credibility of the article the author? s credentials have to be assessed. Mee has achieved her RN, BScN and PhD she has the experience of years of nursing and has written many other articles on different aspects of nursing. One aspect of this article that increased my confidence level in the information was the author provided examples of her own nursing beliefs, values and experiences however there were no statistics or charts which decreases the value of research. The purpose of this article is to inform nurses that everything you do, people are watching you and you could impact there future. The author also states her ideas of what a nurse should include. The main audience intended for this article is nurses and individuals entering the nursing field. The general usefulness Annotated Bibliography: 9 of this article for individuals researching Nursing as a Profession is it allows you to absorb what nursing involves and how important a career in nursing really is. Annotated Bibliography: 10 Castledine, G. (2001). Healthcare professions must work better as teams. British Journal of Nursing, 10 (14), 959-964. Throughout this article the author discusses the essential ingredients of an interprofessional team. The essential ingredients are a common purpose, distinct professional skills, and a process of communicating effectively with each other. If each team member represents his/her own profession? s expertise adequately, then all that is needed is a little teamwork. He clearly states that in the healthcare field working, as a team is an essential factor. The author? s credentials are vital to determine the credibility of the article. Castledine is a Professor and Consultant of General Nursing at the University of Central England. I am confident that this author can be classified as an expert on the topic of Nursing as a profession due to his involvement in Nursing. To further his credibility this article was published by a scholarly refereed journal. The main purpose of this article was to inform individuals in healthcare that teamwork is needed to get the job done, without it you create chaos. The main audience of this article is anyone in the healthcare profession or anyone in a profession where you have to work with other individuals. The usefulness of this article for individuals writing an essay on this concept is it shows you ways in which you can improve your teamwork skills, because without teamwork in a healthcare profession you might as well go into another profession. Annotated Bibliography: 11 Conclusion After completing this Annotated Bibliography it is evident that nurses have an extremely large role in the health care profession. Throughout all five articles there was a connection, showing that without certain skills such as caring and team work nursing is not what it can be. The five selected articles within the Annotated Bibliography have provided me with a great source of information on Nursing as a Profession, I now have background information that will be used in every day class work and upcoming tests and assignments.

Philosophy of Science Essay Example | Topics and Well Written Essays - 1000 words

Philosophy of Science - Essay Example Karl Popper on the other hand was the totalitarian and unadventurous proponent of positivism. Karl and Popper were the contemporaries and criticized each other’s work. The comparison on the philosophies of Kuhn and Popper following attributes are taken into consideration: 1. Differentiation between science and non science Popper opined that science is a method of trial and error. It is a method of assumption and refusal. Science is always accompanied by the group of scholars who check and criticize each other. The foundation of science is its rationality. The openness to criticism should be converted into the willingness of scientists to falsify their theory. Kuhn on the other hand differentiated science and non science through paradigms. Science takes place where there is a major paradigm and non science appears due to lack of dominant paradigm. Thus Kuhn talks about infantile science without a dominant paradigm and a normal science or matured science with a dominant paradigm . He took paradigm as a basic accomplishment which includes both theory and a very good application to the results of observations and experiments. It is very important to keep in mind that though Kuhn differentiated between science and non science through paradigms his differentiation was never based on objectivity. Karl Popper was against the confinement of science within faith and doctrine. Science follows the methods faithfully and these methods are objective. For Popper criticism is a necessary aspect for the scientific method of objectivity. The foundation of scientific rationality lies on the modernist project of reason, doubt, and criticism. To build this rationality science must be open to criticism and adapt critical attitude. Scientific knowledge according to him is snowballing. It is because of the positive approach of the scientists to go through falsification and they should be open to the criticism. According to Kuhn preconception and resistance seem to be the rule ra ther than the exception. He strongly believes that dogma is an essential part in mature science as the scientific paradigm is an open-ended achievement. It is necessary for the scientists to be assertive in their beliefs in paradigm. Then only they can further ensue to the puzzle solving task. 2. Criticism, Dogmatism and Faith Criticism is mandatory to science according to Popper whereas dogma is mandatory in mature science. Popper believes that faith in science is important one and one should stick on to the scientific methods. Kuhn believes that faith should be in scientific paradigm. Popper opines strongly that objectivity in science lies in scientific method. This opinion made Popper to use the concept of provisional knowledge. Scientific methods are enough to evaluate the merits of scientific theories because, as mentioned above objectivity lies in scientific method. This scientific method is paradigmatic for Kuhn. Objectivity is only feasible within the paradigm. Kuhn says tha t this scientific method is not able to evaluate the merits of scientific theories in an objective manner because scientific paradigms occur through extra-scientific factors. Scientific Revolution v/s Scientific progress Popper thinks that scientific progress happens through falsification. After going through falsification, the theory either stands true, or it is taken for granted as a provisional knowl

Michael Ray Charles Essay Example | Topics and Well Written Essays - 500 words

Michael Ray Charles - Essay Example Michael Ray Charles paintings included characters African American characters like mammies, coons, and even sambos. This type of painting precipitated from the infusion of irony and wit on racism issues. His paintings showed old fashioned themes. His popularity as a realism painter resulted to the solo display of his paintings in exhibitions in Art Museum of the University of Houston in Texas, Moody Gallery in Houston, Tony Shafrazi Gallery in New York and even far way Galerie Hans Mayer in Dusseldorf, Germany(Heller and Pettit,205). Further, he presented real-life situations in a subtle way as an artist. The appendix shows that Michael Ray Charles is currently the Studio Art Professor, MFA handling Drawing Painting Subject in the College of Fine Arts at the University of Texas at Austin. His paintings display racism as a reality. He paints pictures in a comedic way. He is popularly known for his use of African Americans to humiliate situations and postures of his time. Mammy, as shown in the appendix, symbolizes an African American woman taking soothing care of a white child(Wallace -Sanders, 143). Furthermore, he was unafraid of the consequences of his convictions. Some sectors believe that Michael Ray Charles’s paintings should be censored from elementary students due to the strong race themes. A person viewing his paintings ought to have the intellectual capacity and maturity to comprehend what is the story behind each of his paintings. Some sectors of American society object to the exhibition of Michael Ray Charles’ paintings because it demeans them especially when the topic of the classroom teacher is racism. Eisner and Day saw many fistfights inside a racially mixed classroom between the 1960s and 1970s when teachers would show films to youngsters of lynching in the South.

Museums are Catalysts for Regeneration Essay Example | Topics and Well Written Essays - 2500 words

Museums are Catalysts for Regeneration - Essay Example But soon, even animal hides, instruments, portraits and sculptures were also displayed. The Greeks then widened the scope of objects displayed in a museum by exhibiting not only statues and paintings but also jewelries, glasses, vases, pottery and ornaments which they offered to their gods. These were however, transported to Rome when the Romans ransacked Greece. Thus began the Romans' romance with works of art. Then Roman temples, palaces and private villas were adorned with these (Alexander 2008, p.4). Japan and China were not left behind in this cultural activity because even before 1000 AD works of art were already manifested in their temples and palaces. It is worthwhile to mention that in Nara City, Japan many of these had been preserved. vanguard for the reposing of important manuscripts, saints' relics, statues, paintings and jewelries. Feudal nobles, coming from the crusades in the Near East, carried with them spoils of war with beauty and added these to their private collections. But museums reached unparalleled importance during the Age of the Renaissance. The Medici family of Florence, collected the most enviable art treasures ever gathered which they ensconced in their palaces. Later these were transferred to the Vatican and made a part of the Papal collection. Then the Uffizi Gallery in Florence was made the repository of the Medici collection (Bennett 1995, p.27). The first great public museum is the Louvre Museum in Paris, which at that time was basically composed of royal collections of King Francis I. For the first time, a museum was opened to the public in 1793. When the Age of Enlightenment came, more museums were opened for public viewing. Some of these were the British Museum, the Berlin Gallery, the Prado in Madrid and the Hermitage in Saint Petersburg (Steffensen 1998, p.13).

Tissue Engineering

Tissue Engineering The first time tissue engineering was introduced it gave the promise to repair or replace damaged organs, the field has dramatically evolved from its origins in the late 1980s. Tissue engineering is a field that is rapidly growing and becoming extremely important within biomedical engineering, it mainly links the rapid developments in cellular and molecular biology together with chemical and mechanical engineering. The graph below shows the amount of money the US federal government is spending on different areas of stem cell research. The National institute of health in the United States defined tissue engineering, in other words regenerative medicine as being: An emerging multidisciplinary field involving biology, medicine, and engineering that is likely to revolutionise the ways we improve the health and quality of life for millions of people worldwide by restoring, maintaining, or enhancing tissue and organ function. (1) Tissue engineering is in fact the application of certain scientific principles brought together to enhance the design, modification, construction, growth, and the maintenance of living tissue. Tissue engineering is divided into two main categories. The first being Vitro, this involves the construction of bioartificial tissues from cells isolated by enzymatic dissociation of a specific donor tissue. Bioartificial tissues are ones which are used as an alternative to organ transplantation, these tissues are composed of natural and synthetic substances. The second category of tissue engineering is Vivo, this involves the alteration and variation of cell growth and function. Examples of applications of tissue engineering include, bone and cartilage implants, formation of bioartificial skin and nerve regeneration. Perhaps the most important concept in tissue engineering is stem cell biology. This is the concept which brought back the idea of using cell based approaches for treating diseases such as heart diseases. Research made on stem cells aims to get knowledge on how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. Stem cells can be defined as ‘a small subpopulation of the proliferating compartment, consisting of relatively undifferentiated proliferative cells that maintain their population size when they divide while at the same time producing progeny that enter a dividing transit population within which further rounds of cell division occur, together with differentiation events, resulting in the production of the various differentiated functional cells required of the tissue. (6) Stem cells are different to other kinds of cells in the human body. All stem cells have three general properties which contribute to their scientific importance. (1) The first is that they are capable of dividing and renewing themselves for long periods. Other kinds of cells including muscle cells or nerve cells do not normally replicate themselves. Stem cells may replicate many times or proliferate. A population of stem cells that proliferates for many months in laboratory can yield millions of cells. The second property of stem cells is that they are unspecialised, the ability of the cells resulting from proliferation to continue being unspecialised like the parent stem cells makes them capable of long term self renewal. In fact stem cells do not have any tissue specific structures that allow them to perform specialised functions. A stem cell does not have the ability to perform the functions a heart muscle cell or a red blood cell would do. In other words, a stem cell cannot work to pump blood through the body like a heart muscle cell, and it cannot carry oxygen in blood like a red blood cell does. The third property of stem cells is that they have got the potential to differentiate into various cell types in the body, this process happens during early life. When a stem cell divides, new cells formed could either remain as stem cells or become another type of cells with a more specialised function. Unspecialised stem cells develop into specialised cells, including heart muscle cells, nerve cells and others. In research two kinds of stem cells have been used, these are embryonic stem cells and non embryonic stem cells, also called somatic or adult stem cells. Embryonic stem cells are ‘undifferentiated cells derived from a 5 days pre-implantation embryo that are capable of dividing without differentiating for a prolonged period in culture. (1) Embryonic stem cells are mainly derived from embryos that result from eggs that have been fertilised in vitro. Scientists have discovered a method to obtain stem cells from human embryos and then growing them in vitro, these cells are called human embryonic stem cells. Human embryonic stem cells are derived from the blastocyst. These are embryos that are around five days old, the time required for blastocyst formation to start after fertilisation in humans. A non embryonic (Somatic or adult) stem cell is ‘an undifferentiated cell found in many organs and differentiated tissues with a limited capacity for both self renewal (in vitro) and differentiation. (1) Non embryonic cells are undifferentiated cells found in a tissue or an organ that can renew themselves and can differentiate and develop specialised cell types of the specific tissue or organ. This type of stem cells is found in many organs and tissues. Adult stem cells are present in the stem cell niche, this is a specific region of each tissue. The main roles of adult non embryonic stem cells in humans are to maintain and repair the tissue in which they reside. The cells remain inactivated and do not divide for long periods of time until a certain disease or an injury in the tissue in which they reside activates them, and they will then start dividing as more cells are required to maintain the specific tissue. Recently researchers came up with new conditions that would allow specialised adult cells to be genetically programmed in order to be able to differentiate into any type of cell. This type of stem cells is called induced pluripotent stem cells. Pluripotent stem cells have unique special characteristics that make them very useful in a wide range of applications. They have the ability to replace damaged cells and provide a new potential for treating disease. They are used in the treatment of extensive burns, and to restore the blood system in patients with diseases such as Leukaemia and other blood disorders. Stem cells can be used to study the development of humans from a fertilised egg and all the processes involved, scientists could Identify the mechanisms that determine whether a stem cell chooses to replicate itself or to differentiate into a specific cell type, and if that is the case what cell type would it be, these information would allow scientists to find out and understand what controls normal human development. In practice a more complete understanding of the genetic and molecular control of these processes may provide scientists with helpful information about how certain diseases arise. This allows scientists to suggest new ways of treating those diseases. The exceptional property of human embryonic and induced pluripotent stem cells that they can renew themselves while maintaining the ability to differentiate into useful cell types. For example, they have been used as a source of human cardiomyocytes. This allowed scientists to go further in research by using those cardiomyocytes in cell based cardiac therapies, cardiomyocytes have also been used in modeling human heart development and in testing drugs. (4) Also stem cells have the ability to provide a source of insulin producing cells, or repair the damaged the pancreatic tissues. This provides another potential to treat diabetes. (5) New medications could be tested for safety on specific cells that perform special functions. A large number of the specific type of cells on which the medications are to be tested is generated from stem cells. Stem cells have the ability to replace cells lost due to other devastating diseases for which no cures have been found yet. Today donated tissues and organs are often used to replace the specific damaged tissues or organs. The problem with that is the fact that, the need for transplantable tissues and organs is a lot more than the supply available. Stem cells, with the ability to differentiate into specific cell types could offer the possibility of providing a renewable source of replacement cells and tissues to treat diseases and replace the damaged tissues and organs. However significant technical barriers concerning stem cells remain, but they are to be overcome by research which is increasing in both importance and scope due to the huge benefits that could be obtained.

The Digital Divide Essay -- Technology Poverty Technological Papers

The Digital Divide When walking into a house, there are many things that can be seen. There may be a television, a phone and maybe a computer. There are lights overhead and warm air all around. There is running water and music to listen to. These may seem like no big deal, but to people in third world countries, this is a dream. People do not realize how lucky they are and what other people go through. If everyone could choose their lifestyle we would all be able to enjoy these luxuries, but that is not the case. In these times we are set apart by a digital divide. A digital divide is the separation of those who can afford technology and those who cannot. Even today, the day of modern technology, more money and better lifestyles, there is still that gap, that divides the digital world. In Heather MacDonalds article, Online Use Sees Digital Divide, MacDonald states that a growing population of people are logging on. This includes adults and teenagers, however, the oldest and the poorest are not logging on. There will always be a digital divide when it comes to technology, but at certain times the gap may be narrower or wider depending on access to that technology. A digital divide can occur between neighborhoods, between cities, between states, countries, and continents. Many factors figure into why the gap is so big. Many kids and teenagers are plugged in because they find that it is fun. It also allows them to feel they are a part of a group. Most adults are connected because some of them can stay at home and work. They can get help from a doctor twenty-four hours a day if their child is sick. They can book a vacation in just minutes, or even bank online According to a recent study by Pew Internet and American Life Project, ... ...have your health, food, money, and a good education. With all these blessings, you are luckier that over half the worlds population. Being connected to the Internet is not one of the most important aspects of life. We first need to worry about getting food, shelter, education, and medical attention to Africa. We cannot solve all of lifes problems, but we can work towards making it better. We cannot stop the digital divide from happening but we can try to prevent it from getting worse. Works Cited MacDonald, Heather. Online use sees digital divide. Daily News 20 Feb. 2001, sec.

Learning and Supporting Teaching in Schools

Certificate Supporting Teaching and Learning in Schools (501/0418/4) Unit 1: Schools as Organisations (T/601/3325) 1. 1 Identify the main types of state and independent schools. The main types of state and independent schools are as follows: * Specialist schools * Academies * City technology colleges * Community and foundation special schools * Faith schools * Maintained boarding schools * Free schools 1. 2 Describe the different characteristics of the different types of schools in relation to educational stages and school governanceThe Key stages are as follows in comprehensive and free schools: * Foundation stage – Normally this is for pupils in reception year, nursery or play group * KS1 – Years 1 to 3 * KS2 – Years 4 to 6 * KS3 – Years 7 to 9 * KS4 – Years 10 to 11 (GCSE’s and/or other equivalent Qualifications are taken in this Key Stage) * KS5 – Year 12 to 13 (A Levels and/or other equivalent Qualifications are taken in this Key Stage) Although standards schools follow this key stage structure, Special schools will run these key stages adapted to the pupils needs i. . a school for learning and physical disabilities may need extra support and resources to ensure that their pupils are achieving the national curriculum standards set for students with learning and/or physical disabilities. The role of the Board of Governors is to run the school. This would include the following: * School Finances and Budgets* Staffing * The School’s Curriculum * Managing School Inspections * To uphold national standards in education Depending on the type of school, depends on the way in which the board of governors operate i. e. or learning and physical disability schools, the board of governors may invest in certain resources to maximise the pupil’s educational potential. Most state schools are funded by the government where as private and independent schools are funded by parents, local funding or charitable inc ome. If the school is a managed school then the local authority employs the schools staff but for private schools and academies it is the school that employs their staff. Managed schools get their pupils from their local catchment areas, the community or school open days.Private or specialised schools may get their students from the local community but may also have an open day or referrals from other educational establishments. Below I have chosen three different types of schools and I will also explain their admissions policy and the age of the children. Grammar Schools Admissions policies – Grammar school admissions policies are normally set by the local council. All applications initially must go through the local council. Also with grammar schools, there is often a test in which a child has to take and pass in order to be accepted into the school.This is due to the fact that grammar school children are highly educated. Age of pupils/students – pupils are normally enter into grammar school at the age of 10/11. They will be working on key stage 4 when entering the school. On the fourth year of school, pupils go on to key stage 5 working on GCSE’s and NVQ’s. In some cases, pupils in grammar schools may take their A Levels early or higher qualification. Pupils in grammar school now leave at the age of 17. Montessori schools Admissions Policy – in Montessori schools the children are interviewed by a teacher to make sure that they fit in with the ethos of the school.A payment is needed from parents in order for children to attend the school. An educational or psychological assessment is needed by the school in order for the child to be admitted. Montessori schools do not admit children midterm unless they are transferring from another Montessori school. Age of pupils/students – In Montessori schools, they admit children from 18 months up to 18 years old. Montessori schools have a holistic method of educating children so that they express freedom and self discipline. Steiner schools Admissions policy – The admissions policy is pretty much the same as a Montessori School.Age of pupils/students – In Steiner Schools, the age of children is from 3 years old to 16. Like a Montessori school, a Steiner schools tackle educating in a holistic manner in order to develop the whole child. Not just educational. 2. 1 Describe roles and responsibilities of staff related to the school Below are 4 Roles within a school and their responsibilities: * Teacher – To plan, deliver and evaluate lessons, to encourage pupils with their learning development, Make learning as fun as possible, create reports on pupils learning to parents and be a role model for pupils. Lunchtime Supervisor – Help set up dining areas, Supervise pupils with toileting and hand washing, resolve and report conflict and encourage independence at mealtimes. * Clerical Staff – To keep the school running smoothly by d irection of the Head Teacher, maintain and report attendance records, Perform administrative duties which may include writing letters to parents by direction of teachers and head teacher. * School Librarian – Plan and oversee the management of the library, Ensure an equality of opportunity for all staff and pupils, Complete reports to/ and inform the governing body of stock and library resources.Also another role within a school is a Teacher’s Assistant. To reflect his or her role within the school I have written a day in the life of a Teacher’s Assistant. 8. 15am  My day starts as soon as I get to school, when the class teacher, who I work alongside, outlines the plan for the day ahead and I help to set up the activities. 8. 55am  The day begins for the children. As they wait with their parents and carers in the playground, I approach the gate and greet the children as the bell rings. I briefly chat with a few parents as they pass on messages, help children take their coats off in the cloakroom and follow them into the classroom.As the teacher takes the register I check the ‘Home-school communication books’ for any other messages. 9. 05am  The first activity for today is PE and today will be the first time that the children have taken part in PE in our main hall! Surprisingly the children are quite quick at getting changed into their gym kits. Today we practise moving in and out of spaces in different ways – jogging, marching, large strides and small footsteps. 10. 25am  It’s playtime and time to get coats on and join the rest of the infants in the playground.While the children are out at play I prepare their morning snack. 10. 40am  In from play and it’s time for hand washing, then fruit and milk. After this it’s activity time and the children choose from a range of activities both inside and outside. Today I’m inside making teddy bear puppets, encouraging the children to stick a corresponding number of buttons onto their bear. Midday  It’s lunchtime and we take the children into the dinner hall to be greeted by their lunchtime supervisors. I pop back to the staffroom and have my lunch and chat with other members of staff.Then it’s time to set up for the afternoon activities. 1pm  The children come in from lunch. Time for a quick register and this afternoon I support children building train tracks, investigating in the sand and experimenting with drawing and writing – a busy hive of activity, and lots of observational assessment! 2pm  Playtime again and this time I’m on duty supervising the children with another member of staff. 2. 20pm  Time for a few more bears and buttons with those who are keen and once these are done I join in with some children who are doing some jigsaw puzzles.Today, I have a breakthrough – a child who has been reluctant to talk and has been communicating through gestures, actually initiates a conversation with me! 3. 20pm  Home time for the children as we look out for the children’s parents and carers, and send them off happily! Once the children have all been collected it’s time for a final tidy up and discussion with the class teacher about the day’s events. 3. 45pm  Time for me to go off home, too! 2. 2 Describe the roles of external professionals who may work with the school For this section I have created two â€Å"A day in the life of†¦.. journals to describe what the role is of an external professional within the school The first role I have chosen to talk about is a Peripatetic Music Teacher. 09:30 am I arrive at the school and sign in at the school reception desk. I am then shown by the music head of department to the room in which I will be teaching. Whilst walking to my designated room, myself and the department head discuss what the needs and aims are of the pupils that I will be teaching today. 10am My first pupil arrives. At first the pupil and I discuss what we are going to be teaching her over the next 45 minutes.Also we talk about if there are any issues or questions she may have with learning the flute. There are no issues so we continue on with the lesson. 10:15am I start to teach my pupil on how to play the flute and to work through some theory activities as my pupil is going for her grade 3 flute exams next week. 10:45am After a great lesson with my first pupil, she leaves to go back to her academic class. I write up an evaluation of what my pupil has learnt and things for improvement. This evaluation will be spoken about at the end of the day with the department head. 1am My second pupil arrives and we do exactly what we did for my first pupil between 10 am and 11 am. My second student is also going for his grade 3 exams in playing the flute as well. I also write an evaluation on the lesson which will also be discussed with the head of department. 12am I break for lunch for an hour. I photocopy the two evaluations that I have written up this morning and left them on the department head’s desk. From 1pm to 2pm and 2pm to 3pm, I teach one pupil at a time and discuss their flute exams. 3pm I meet with the department head to discuss the 4 pupils’ progress and needs.Today was very good as they are all making brilliant progress and are all ready for their exams. 3. 30pm It is now home time for me so I go to the room I was assigned and clear up. Off I go and I felt today was a really productive day. The next professional I will write about is a Road Crossing Patrol. 7. 45am I arrive at the crossing area where I am assigned. I walk down the road and turn on the school crossing warning lights. Whilst I am turning on the crossing patrol lights, I check to see if there are any dangers when helping to cross the road with children and parents.There are no dangers so I return to the crossing place. 8am I put on my uniform overcoat and hat and help parents and children cro ss the road with my stop sign remaining friendly at all times. 9. 30am All the school children are in school now so I turn off the crossing patrol lights and head off home. 2. 45pm I arrive back at my crossing patrol and switch on the crossing patrol lights. Again I check for dangers in the area. There are no dangers so I return to my post. I wait for the school children and parents to help them cross the road with my stop sign remaining friendly at all times. . 30pm It is my home time now so I turn off the school crossing patrol lights and head off home. 3. 1, 3. 2 and 3. 3 Aim and Objectives How are aims and values decided? Aims and values are decided through consultation to the stakeholders for the school. Stake holders can include the following: * Governors * Head teacher * Parents * School staff * Children * The local community How are aims and values communicated? Aims and values can be communicated to anyone involved in the school by using the following: * Letters to parents *Displays within the school On the schools website or the internet * Presented within meetings An aim is the context within which schools must develop their own education. A value is a common set of values underpinning the curriculum and the work of schools. E. g. Caring, Confidence building, creative, Contribution and community. The School can do lots of things to show/demonstrate its values or aims: Some examples of which are shown below. Values * Value everyone as an individual – We listen to everyone and let them have their say through circle time activities, show and sell and through the schools council.Understanding of staying safe and being healthy – Get speakers from outside agencies (Such as the police), Visits to Streetwise, Life Education Bus, through circle time activities and PSHE (SEAL) lessons, Training for staff, have a healthy eating policy and healthy snack times. * Provide a learning environment appropriate to the individual – Differentiation in planning and activities, Different learning styles or catered for (e. g. Visual, Auditory or Kinaesthetic), SEN pupils are identified and supported and support staff used and brought in if required. To value every child’s contribution – Recognising pupils input on activities, rewarding pupils for their contributions, award evenings for pupils who have made significant contributions, * To develop a caring attitude towards others – Pupils and school staff alike to respect each other, teachers to identify pupils with SEN and to give them extra time to complete an activity where needed, school staff to be a good role model for pupils. * For pupils and staff to have a positive approach to leaning – eachers to make an activity as fun as possible, the school will be attractive to the outside and to promote fun creativity within the classroom, promote educational independence to pupils. 4.1 Identify the laws and codes of practice affecting work in schools Belo w are some of the laws and codes of practice that are affected by schools: * Disability Discrimination Act 1995 * The National Curriculum (a statutory document, published in 1999) * The Children Act 1989/2004/2006 * Every Child Matters * Special Educational Needs and Disability Act 2001 * Education Act 1996 4. Describe how laws and codes of practice promote pupil wellbeing and achievement Data Protection Act 1998 The Data Protection Act 1998 promotes pupil wellbeing. This is because all information about a pupil is on a need to know basis. Therefore this ensures that no information about a child that is given out unnecessarily. This law can also protect the child from harm and/or abuse. Special Educational Needs and Disability Act 2001 This law states that a child with special educational needs or who has a disability is entitles to a fair education. This can include tailoring learning to the child’s abilities.It is the schools responsibility to have specific resources for a child to excel in their education. Schools should allow extra time with special educational needs or children with disabilities in order for the children to understand what is asked of them. Equalities Act 2010 This act states that no one should be discriminated in any way and also to be included. For children in schools, staff and pupils should not discriminate and also to tackle discrimination. This can be any form. This will excel pupils’ wellbeing and achievement because children will not be in fear of being left out or discriminated. . 1 Describe why schools have policies and procedures Please see worksheet A5 Policies and Procedures 5. 2 Identify policies and procedures in schools Below is an exhausted list of policies and procedures that can be placed within schools: * Safeguarding * Attendance * Uniform * Fire Safety * Admissions * Behaviour * Accidents * First aid/ Medical * Health and Safety * Anti-bullying * Achievement * Child Protection * Homework* SEN * Teaching and Learning * Equalities * ICT * Subject Specific Policies * Complaints * Equal Opportunities * Confidentiality * Performance Management Disciplinary * Marketing * Finance * Grievance Unit 2: Child and young person development 1. 1 Child and young person physical development from birth to 19 years old Age| Physical development| Birth to 1 month| A newborn child will gain 1 ounce a day after initial weight loss in the first week. Also a child will discover his or her reflexes like grasping, sucking and clenched fists. A child’s vision will be at 8 to 12 inches and can lift head slightly. | 1 to 2 months|A child will be able to lift head to a 45 degree angle. And be able to gurgle and vocalize. 2 to 3 months | A child will be aware of other people by staring. | 3 to 4 months| A child will not be able to chuckle, smile and make use of more vocal techniques. A child will be able to kick legs | 4 to 5 months| A child will gain approximately 5 to 6 ounces per week. He or she will improve gripping techniques. Also he or she may be able to pull him/her self to sit up and roll on each side of their body. A child may also be able to bare weight on his or her legs. He or she may be able to laugh and giggle. | 5 to 6 months| A child will be able to sit up without support.He or she may be able to feed themselves with a cracker or biscuit. | 6 to 7 months| A child will be able to sit up. He or she will reach for desired toy(s). Also a child will be able to pass toys from one hand to another. | 7 to 9 months| A child will be able to shout for attention and also be able to say the odd word i. e. â€Å"mama† or â€Å"dada†. | 9 months to 1 year| May start to crawl or shuffle. Child may start to use the pincer grip to hold on to items or food. Also he/she may be able to pick up objects but will only be able to release by dropping or throwing. 1 year to 18 months| May be able to use a spoon and self feed. During this period a child will start to walk and p ull themselves up in order to start walking. They may also use furniture or toys to aid them to walk. | 18 months to 2 years| Able to use preferred hand for drawing, playing and drawing. A child is able to self feed fully at this stage. Also able to walk up and down stair but with 1 step at a time. | 2 to 3 years| A child will be able to walk independently and start to walk on his/her tiptoes. Also he/she will be able to undo buttons and kick shoes off.Also aid in undressing. | 3 to 4 years| A child will be able to brush his/her own teeth. He/she will start to run and hop. Child will also be able to walk on a line and start to walk backwards. | 4 to 5 years| Will be able to dress and undress unaided. Use scissors accurately, start to write own name and starts to run quickly. | 5 to 7 years| Uses pens and pencils for detailed drawings. Also builds intricate models. | 8 to 12 years| A child will be able to improve on physical skills that they already have developed. For girls puberty starts within this phase of development.Gils will start to develop more as a woman. | 13 to 16 years| A boy’s puberty will start in this time frame but will tend to be stronger than a girl. A boy will start to develop as a young man. This would include the appearance of facial hair and voice breaking. | 16 to 19 years| Most of the child’s physical development has now been completed. | Percentiles Percentiles are a method in which you can measure the progress of a child’s development. A measuring tool that is often used is a percentile chart. Percentile charts normally measure height and weight.Normally if a child’s weight is at a percentile of 75% then the height is normally 75% as well. If these percentiles are very different from each other then this shows that the child is not developing correctly. The higher the percentile the more a child is developing in a certain area. Also if a percentile is lower, then the child is not developing as quickly compa red to the average child. Milestones Milestones are often stages in a child’s life at which a child has reached an achievement in their development. As mentioned in physical development, a child can start crawling or shuffling at about 9 months.Also a child may start to walk independently or start to talk. These are also milestones. 1. 2 Describe with examples how different aspects of development can affect one another Different aspects of development affect one another. 2. 1 Describe with examples the kinds of influences that affect children and young people’s development a) Background Parental expectations – If a parent has high expectations of a child then the child is able to develop at a faster pace and in turn a child will then be able to do a lot more at a young age.This works in the opposite way if a parent has low expectations. An example of this would be if a mother sits with a child and reads with him/her. The child is then able to build up his/her ab ility to read quicker and learn new words quicker. This also makes them have a higher academic level to a child whose mother who does not have high expectations. If a child’s mother has high expectations, then the child will develop academic skills faster. Conflict between parents – If there is conflict between a child’s parents then a child will pick up on this and will learn the actions from their parents.An example of this is when parents are constantly arguing in front of a child, the child then learns that is it ok to shout at other people. A child may develop low self esteem because there is constant conflict in the home. The child may not feel safe within the home as they may be frightened that the parents may shout at them as well. In turn the child may not develop good social/emotional skills. b) Health Asthma – If a child has asthma, this may affect their physical and social development. An example of this is that a child may not be able to do c ertain activities that his/her peers take part in.Also certain asthma drugs can stunt growth there for a child will not grow as quickly or as high as their peers. General poor health – If a child has generic poor health they will not be able to develop socially, emotionally and physically. This is because a child may not be well enough to interact with his/her peers therefore restricting social development. If a child is to be constantly unwell, this can then lead to other illnesses which in turn will restrict physical development and cause future health issues.When a child is constantly unwell, the child will feel upset and may fall into depression. This will then restrict emotional development as a child will not have the chance to feel happy. c) Environment Housing (Living in crowded accommodation) – A child will not be able to develop emotionally or socially when living in confined or cramped living circumstances. The reason for this is because a child needs a plac e in a home to call their own so that they can discover themselves without constant influence from household members.Availability of jobs – If there is a high availability of jobs; a child’s family will then be able to work. This in turn develops a child socially and emotionally. Also a child will be better cared for enabling the child to develop in all areas correctly. This is because a child will be cared for correctly. This will then make the child develop physically and socially. 2. 2 Describe with examples the importance of recognising and responding to concerns about children and young people’s development

CIVIL LIBERTIES AND WAR essays

CIVIL LIBERTIES AND WAR essays At times in American History government has been seen as a danger to freedom from which individuals need protection or, conversely as a protector of citizen liberties. This portion of my paper will explore the position the government has adapted during different eras of American History. Exposing corruption, expanding democracy, making reforms, improving working conditions and the way of life is what characterized the progressive movement. Citizens demanded a change in numerous areas such as business, labor, economy, consumer affairs and an increase of democracy. The Progressive Era was marked with the arrival of President Theodore Roosevelt who fought for the good of the common man. During the Progressive era many large corporations had complete control of the services that they produced, Roosevelt broke up these monopolies. He was also a big supporter of labor he tried almost everything with in his powers to help the citizens of the United States. Roosevelt set up child protection laws, which were used to prevent children from working in factories. Child protection laws also reduced the amount of time children were allowed to work. Roosevelt set up workers compensation. He tried his best to help consumers, by proposing to congress the Pure Food and Drug Act. This act was used to protect citizens from unsafe medicines and food by demanding; that all food must be inspected, and the use of addictive drugs in prescription medicine be prohibited. During the Progressive Movement the government played a role of protector of the people, by fighting for equality in the labor force. Man, woman, and child benefited from the Progressive Movement. Big businesses were regulated and the civil liberties were protected with the help of government regulations. The Progressive Movement was the start of a new American government that paid more attentions to the citizens of the U.S. The New Deal was the name given to President Franklin D. R...

The University of Southamptons Print centre Essays

The University of Southamptons Print centre Essays The University of Southamptons Print centre Essay The University of Southamptons Print centre Essay A report on an Ethnographic pilot study of the University of Southamptons Print centre Introduction. This report follows an ethnographic pilot study into the universitys print centre. We were required to view the Print centre through the eyes of management consultants relating its operations to material covered in lectures. Background to the Print centre. Find out how long it has been running. The Print centre was initially setup to cater for the specialist print needs of the university. This has since changed and it is now also widely used by other organisations and the public. The centre has one manager and nine subordinates who specialise in different parts of the process. Located in a two-storey house on 99 University road it is soon to be demolished to make way for University Boulevard with the site of relocation as yet unconfirmed. Function of the Print centre. The Print centre offers a wide range of services focused toward the growing requirements of its users. Whilst the majority of the work undertaken is still conventional printing such as booklets and leaflets, they offer other services such as t-shirt printing and spine binding. Structure and culture of the Print centre. In relevance to the findings of Burns and Stalkers 1961 study into organisations The Management of Innovation the Print centre leans more toward a mechanistic structure. The characteristics that make it so, do however suffer a wide degree of variance due to the small number of staff. Specialisation and departmentalisation of work is apparent with each member of staff trained in one particular area. However the direction and decision making within the centre appears to take a more collective approach as opposed to management being the controlling force. It is easy to understand why, as the size and hierarchical nature of the centre makes consultation with, and influence from staff inevitable as described by Laurie J. Mullins. He says of small organisations the definition of authority and responsibility, and the relationship between members of the organisation can be established on a personal and informal basis (2002, p. 530). This fluctuation of the mechanistic characteristics highlights the contingency approach in that the environment shapes the structure of the centre. The specialisations of staff in the centre combined with the formalised work process are covered by what Charles B. Handy named the role culture (1976, p. 190). He likens this form of organisational culture to a Greek temple. This metaphor can be deconstructed when looking at the centre. Handy goes on to say The role organisation rests its strength in its pillars, its functions or specialities (1976 p. 190). Indeed each pillar is represented by one of the specialist areas, each needing to be as strong the others to ensure a solid and sound building. Holding the pillars in place is the pediment represented by the manager and her controlling influence, disseminating her authority down. Stakeholders. As the university owns and uses the Print centre the most they can be regarded as the primary stakeholder. It is for this reason that university work takes priority in busy periods. However if the balance shifted and customers from outside became the greatest users the bias would have to be addressed. The paper supplier is another important stakeholder in the organisation. The centre relies on JIT for their paper deliveries. This situation gives the supplier indirect influence over management decisions, for example if the manager sought a cheaper supplier they would have to offer the same level of reliability and service, a risk perhaps not worth taking. As mentioned above the centre has nine staff and one manager allowing the staff to exert a degree of control over management decisions, especially when acting as a collective. Ethical issues. British society today is heading toward a state where social responsibility, in an ethical sense, is no longer implored and congratulated but expected. The centre reflects this growing consensus by recycling of over 70% of its waste. They also offer the use of recycled paper if the user requests it and only use eco-friendly paints. In recognising the social contract between the centre and society they lean more toward the corporate social responsibility approach than Milton Friedmans profit maximisation beliefs. There is a possibility that the imminent relocation may raise some ethical issues for employees. However when analysing the relocation in respect to stakeholder theory, as the centre is still to remain on campus it is difficult to see how any party will be adversely affected. How well is the Print centre managed? Following studies undertaken by the Management Charter Initiative in 1991 entitled Crediting Competence they produced a set of four occupational standards employers thought managers should competent in. These were the ability to manage activities, resources, people and information. The activities are well managed with the product continually meeting customers requirements as discussed above. In terms of resources money is well managed. The centre is supposed to be a non-profit making organisation and as such prices are set accordingly. They do however make a profit, which is reinvested in new equipment so as to remain effective. The management of the premises is perhaps not effectively or efficiently managed with the flow of work-in-progress being a disjointed one, although this can partially be put down to the location. The relocation of the centre should provide scope for improvement here. Management of staff appears to be first rate with staff seeming happy and content in their work (the Hawthorne effect may be applicable). Information about the management of information was difficult to gather. In terms of work however all work is carried out from a job-sheet detailing the specifics of any particular job. Stocks, schedules, price quotes and other information can be accessed from a computer.

The Four Forces of Evolution Assignment Example | Topics and Well Written Essays - 250 words

The Four Forces of Evolution - Assignment Example This genetic drift then led to the splitting of the small population into more populations with varying species. In connection with this, the variation of species as a result of the genetic drift led to the isolation of species as well as occupation of new environments. This isolation however did not last for long, the exponential growth of the population as a result of reproduction exerted pressure on the minimized resources leading to the populations moving to other areas where they interacted and reproduced with other species. It was a result of this gene flow that other species with varying characteristics emerged leading to the formation of new populations. Survival of the emerged new population depended significantly on the natural selection force that enabled them adapt the new environment. Additionally, natural selection force made the organisms develops important traits as well as pass their variations to the progeny in order to enhance their survival. Thus, natural selectio n led not only to speciation, but also to the advancement of the genetic makeup of species (Haviland, McBride, Prins and Walrath 44). As time went by, the environmental conditions also continued to change leading to alteration of the pattern of genes in organisms in a process referred to as mutation. Just like natural selection, the random mutation of genes also led to the emergence of new species that made up different populations (Haviland, McBride, Prins and Walrath 42). Since the environmental conditions are prone to continuous changes, it is evident that mutation will remain being the ultimate source of evolutionary changes in organisms. In conclusion, the process of evolution is well defined by natural selection, gene flow, gene drift, and mutation. However, the continuous environmental changes make mutation the main source of genetic variations between species from different

Physical science Essay Example | Topics and Well Written Essays - 750 words

Physical science - Essay Example Thirdly, fission and fusion reactions possess the capacity turn the energy associated with ordering of subatomic particles into nuclear energy (How is Energy Converted). Fossil fuels pertain to fuels formed out of the organic remains of prehistoric plants and animals that undergo natural process of anaerobic decomposition and these fuels are chiefly comprised in coal, gas, and oil. It normally takes nearly 700 million years for decaying plant and animal matters to be fossilized upon exposure to extreme levels of heat and pressure into usable fossil fuels which are mostly rich in carbon with coal, natural gas, and petroleum by composition. Being a non-renewable source of energy, fossil fuels may be volatile or non-volatile as materials ranging from those of minimal C to H ratios as methane gas and liquid petroleum to materials with heavier carbon content than hydrogen as in the case of anthracite coal. In modern times, fossil fuels are confronted with the perils of continuous depletio n at a rate that alarmingly exceeds that of their production which implies that renewable substitutes with equivalent advantages ought to be discovered and settled at for corrective resolution (Lecture 10: Fossil Fuels as Energy Sources). Aside from being a flexible non-renewable energy source, according to their structure, depositional environment, and thermal reactions, fossil fuels draw a potential attraction due to the fact that most of world’s reserves of oil and natural gas come from deformed rocks whereas a great quantity of coal may be derived from sedimentary rock layers that do not undergo deformation. Sediments are readily found everywhere on which are comprised marine organic matter filled with oil and gas in high proportions to make opulent fossil fuel amounts. Because of low oxygen concentration on environments in which massive deposits are preserved and coal forms that gather toward bogs and swamps, fossil fuels can be acquired with much convenience. Under natu ral circumstances, fossil fuels are made beyond human intervention since thermal processes may occur spontaneously after decomposing organics goes through preservation to become fossil fuels at a later time. Aside from fossil fuels, renewable alternatives could be wind energy and geothermal energy or heat derived from the earth by means of a natural geologic process. As a form of solar energy, the energy of the wind is found to comprise turbulent masses of air rushing to even out the differences in atmospheric pressure formed when the sun heats the air more in one place than in another. For centuries, wind power has been utilized extensively in pumping water, grinding grain, and producing electricity of the modern age. Wind turbines as major replacements to windmills perform the course of wind power upon conversion of the wind’s kinetic energy to mechanical energy which sustains small to large farms and villages with clean and renewable loads of electricity (Freris, 1990). Mo dern technological advancements in the fields of engineering and science have revolutionized the old design in windmills with a flexible range of
