Nuclear Power And Its Uses :: essays research papers

Nuclear Power and Its Uses At first nuclear power was only seen as a means of destruction but after World War II a major effort was made to apply nuclear energy to peacetime uses. Nuclear power if made when a nucleus of an atom is split to release a powerful burst of energy. Though technological advancements nuclear power now supplies us with new medical aids, a new power source and new ways to do scientific research. New medical advancements are being produced rapidly due to nuclear power. Nuclear material is now being used to treat diseases. Pacients suffering from cancer can then be exposed to the healing effects of the radiation under controlled conditions. The radiation of the nuclear energy can help in medical tests. Radioactive phosphorus is an important diagnostic aid. It is injected into the veins of a patient, it concentrates in the cells of certain brain tumors. Thyroid gland strongly attracts iodine. Radioactive iodine is used both in diagnosing and in treating diseases of the thyroid. Nuclear power is changing the face of medicine with new cures and tests that will cure millions.. Nuclear power can be converted into strong and efficient nuclear energy and be used for many purposes. Nuclear power reactors generates heat that is converted into steam. The steam can be used directly for energy. This energy is used in transportation. Most military subs are now ran by nuclear energy. The most used purpose of nuclear energy can also be used to generate electric power for example in a commercial nuclear power plant. Another way to produce nuclear energy is by gas-cooled reactors with either carbon dioxide or helium as the coolant instead of water. This method is used mainly in commercial nuclear plants in the United Kingdom and France due to the lack of freshwater. With growing popularity nuclear energy will definitely of the future with new ways to use this energy in a positive manner. Scientists can now use nuclear power for biological research to help understand life more. Radioactive isotopes have been described as the most useful research tool since the invention of the microscope. Physiologists use them to learn where and at what speed physical and chemical processes occur in the human body. Isotopes are also used for agricultural Biologists use radioactive isotopes to see how plants absorb chemicals as they grow. With radioactive cobalt, botanists can produce new types of plants. Structural variations that normally take years of selective breeding to develop can be made to occur in a few months. Many believe that nuclear power is too destructive and as such should be

A Brief History of School Guidance and Counseling in the United States The history of school counseling formally started at the turn of the twentieth century, although a case can be made for tracing the foundations of counseling and guidance principles to ancient Greece and Rome with the philosophical teachings of Plato and Aristotle. There is also evidence to argue that some of the techniques and skills of modern-day guidance counselors were practiced by Catholic priests in the Middle Ages, as can be seen by the dedication to the concept of confidentiality within the confessional.Near the end of the sixteenth century, one of the first texts about career options appeared: The Universal Plaza of All the Professions of the World, (1626) written by Tomaso Garzoni. Nevertheless, formal guidance programs using specialized textbooks did not start until the turn of the twentieth century. The factors leading to the development of guidance and counseling in the United States began in the 1890 s with the social reform movement. The difficulties of people living in urban slums and the widespread use of child labor outraged many.One of the consequences was the compulsory education movement and shortly thereafter the vocational guidance movement, which, in its early days, was concerned with guiding people into the workforce to become productive members of society. The social and political reformer Frank Parsons is often credited with being the father of the vocational guidance movement. His work with the Civic Service House led to the development of the Boston Vocation Bureau. In 1909 the Boston Vocation Bureau helped outline a system of vocational guidance in the Boston public schools.The work of the bureau influenced the need for and the use of vocational guidance both in the United States and other countries. By 1918 there were documented accounts of the bureau's influence as far away as Uruguay and China. Guidance and counseling in these early years were considered to be mostly vocational in nature, but as the profession advanced other personal concerns became part of the school counselor's agenda. The United States' entry into World War I brought the need for assessment of large groups of draftees, in large part to select appropriate people for leadership positions.These early psychological assessments performed on large groups of people were quickly identified as being valuable tools to be used in the educational system, thus beginning the standardized testing movement that in the early twenty-first century is still a strong aspect of U. S. public education. At the same time, vocational guidance was spreading throughout the country, so that by 1918 more than 900 high schools had some type of vocational guidance system.In 1913 the National Vocational Guidance Association was formed and helped legitimize and increase the number of guidance counselors. Early vocational guidance counselors were often teachers appointed to assume the extra duties of t he position in addition to their regular teaching responsibilities. The 1920s and 1930s saw an expansion of counseling roles beyond working only with vocational concerns. Social, personal, and educational aspects of a student's life also needed attention. The Great Depression of the 1930s led to the restriction of funds for counseling programs.Not until 1938, after a recommendation from a presidential committee and the passage of the George Dean Act, which provided funds directly for the purposes of vocational guidance counseling, did guidance counselors start to see an increase in support for their work. After World War II a strong trend away from testing appeared. One of the main persons indirectly responsible for this shift was the American psychologist Carl Rogers. Many in the counseling field adopted his emphasis on â€Å"nondirective† (later called â€Å"client-centered†) counseling.Rogers published Counseling and Psychotherapy in 1942 and Client-Centered Therapy in 1951. These two works defined a new counseling theory in complete contrast to previous theories in psychology and counseling. This new theory minimized counselor advice-giving and stressed the creation of conditions that left the client more in control of the counseling content. In 1958 the National Defense Education Act (NDEA) was enacted, providing aid to education in the United States at all levels, public and private.Instituted primarily to stimulate the advancement of education in science, mathematics, and modern foreign languages, NDEA also provided aid in other areas, including technical education, area studies, geography, English as a second language, counseling and guidance, school libraries, and educational media centers. Further support for school counseling was spurred by the Soviet Union's launching of Sputnik and fears that other countries were outperforming the United States in the fields of mathematics and science.Hence, by providing appropriate funding for educa tion, including guidance and counseling, it was thought that more students would find their way into the sciences. Additionally, in the 1950s the American School Counselor Association (ASCA) was formed, furthering the professional identity of the school counselor. The work of C. Gilbert Wrenn, including his 1962 book The Counselor in a Changing World, brought to light the need for more cultural sensitivity on the part of school counselors.The 1960s also brought many more counseling theories to the field, including Frederick Perl's gestalt therapy, William Glasser's reality therapy, Abraham Maslow and Rollo May's existential approach, and John Krumboltz's behavioral counseling approach. It was during this time that legislative support and an amendment to the NDEA provided funds for training and hiring school counselors with an elementary emphasis. In the 1970s the school counselor was beginning to be defined as part of a larger program, as opposed to being the entire program.There wa s an emphasis on accountability of services provided by school counselors and the benefits that could be obtained with structured evaluations. This decade also gave rise to the special education movement. The educational and counseling needs of students with disabilities was addressed with the passage of the Education for All Handicapped Children Act in 1975. The 1980s saw the development of training standards and criteria for school counseling. This was also a time of more intense evaluation of education as a whole and counseling programs in particular.In order for schools to provide adequate educational opportunities for individuals with disabilities, school counselors were trained to adapt the educational environment to student needs. The duties and roles of many counselors began to change considerably. Counselors started finding themselves as gatekeepers to Individualized Education Programs (IEP) and Student Study Teams (SST) as well as consultants to special education teachers, especially after passage of the Americans with Disabilities Act in 1990.The development of national educational standards and the school reform movement of the 1990s ignored school counseling as an integral part of a student's educational development. The ASCA compensated partially with the development of national standards for school counseling programs. These standards clearly defined the roles and responsibilities of school counseling programs and showed the necessity of school counseling for the overall educational development of every student. Major Roles and Functions for School Counselors

Audience Analysis Essay

Communication is one of the most important skills that an individual can possess when presenting to a group of people. The audience should always be focal point of the presenter as communication is an important foundation and can often determine the success or failure of a message being received. When communication is done properly it can build respect and trust between groups and help identity the issues at hand. The presenter must have a good understanding of the audience’s culture in order to effectively communicate with the group. In this assignment I have been asked to present quarterly sales information in an in-person meeting to a group of stakeholders that includes managers, salespeople, and customers. I have been asked to answer a number of different questions before I present my information to the audience. The following questions will be answered in this paper. 1.What are audience characteristics you need to consider?2.What communication channels would be appropriate and why?3.What are some considerations that you must keep in mind given the diversity of the audience?4.What would you do to ensure that your message is effective?Before you can prepare a presentation you must consider the characteristics of your audience. I know that my audience consists of managers, salespeople, and customers of this particular organization. Because I have identified my audience I now have a better understanding of the audience’s knowledge of the subject. I also understand their interest in the subject; I understand that the different groups of individuals may only be interested in certain results of the quarterly sales information that is being presented. Managers and salespeople may have different subject knowledge than the customers. I will needs to address the different needs of all parties in attendance. I will have to customize certain parts of my presentation in order to address the specific needs of each group within the audience. I will also need to understand what the audience is expecting to learn from my presentation. I should be able to meet and exceed their expectations and the audience should walk away with their questions answered and explained as well as have a better understanding of the quarterly sales information that was presented to them. Because this is an in-person meeting certain communication channels are more appropriate than others. Power-point presentations would be an appropriate method of communication between the presenter and the audience. This is an effective method because it not only allows the presenter to discuss the statistics; but will also allow the present to show the audience the statistics in detail and all together as a group. Printed handouts or documents are another method of communication that would be considered appropriate in an in-person meeting. This method allows the audience to take part in reading the information provided and also gives them something to take with them from the meeting for future reference. Because the majority of the information is being presented orally, the presenter must consider their own body language and speech effectiveness to the audience. Body language and speech are both very important as the audience will be feeding off of the enthusiasm of the presenter. If the presenter gets the attention of their audience it is important to keep it in order to effectively communicate the information. Because there is diversity in the audience certain considerations must be kept in mind when presenting quarterly sales information. Each group will have different levels of interest in the information being presented. The customers will probably not have the same level of interest in certain aspects of the presentation as the managers and salespeople. Another consideration that the presenter must keep in mind is the information that is being communicated to the group. There is a certain amount of statistical data that the organization might not want all the members of the audience to know about. This information might be better presented in a manager’s only meeting. Other considerations that a presenter may want to keep in mind given the diversity of the audience is the average age, gender, culture background, education, economic status, and group memberships of the attending audience. These considerations individually may not have a big impact on the methods of communication chosen by the presenter, but together will allow the presenter to understand the diversity of the audience to which the information is being communicated. To ensure that the presentation is a success and the information is received effectively I would make sure that I have a concrete agenda and use it. I would also make sure that I interact with the audience, for example when presenting the sales data I might ask the audience if anyone has any suggestions to help increase the sales in a particular area. I would ask some open-ended questions to help encourage audience participation. I would also ask the audience to participate in constructive group discussions and would frequently check for group consensus on particular issues and decisions. At the end of the meeting I would survey the group through E-mail, fax, letter to ensure that the information that was presented was received and understood. I would also make myself available to answer any questions that may need clarification on an individual level. References Locker, K., & Kienzer, D. (2008).
