Classroom Management Essay

Classroom rules and procedures shape the learning experience, allowing students to understand what is expected of them and foster a positive learning environment within the classroom. Rules are necessary within the classroom and society in general. The classroom is often times one of the first experiences that students have to teach them about life and expectations as members of society. For this topic, two in classroom activities and the behavioral expectations for these will be examined: the use of learning centers and cooperative learning groups. We will also consider two out of classroom activities and the behavioral expectations associated with these: field trips and assemblies. Finally, we will discuss evaluation methods that can be put in place to determine the level of understanding of behavioral expectations for these situations. For the first in-class activity, learning centers, we will first take into consideration the size of the group. Learning centers are most commonly small group activities consisting of three to four students. Learning centers should be areas in which students can complete simple tasks that support and reinforce material that is being taught in the classroom. Say, for example a class is learning about plant life. The teacher lectures on the topic and has a whole class activity that is to be completed by the end of the week. Learning centers can reinforce this topic across a wide variety of subjects. There could be a writing center in which students are given a topic such as the stages of plant growth. A math center which might include counting seeds or other plant related material and a science center that could outline the stages of plant growth would reinforce material covered in large group instruction. There could be a computer learning center where there might be a matching game, where students match stages of a plant’s life cycle with vocabulary words. Throughout all of these activities, rules of behavior would be of utmost importance. Small group activities such as these learning centers usually have minimal teacher supervision. Here is a situation in which behavioral expectations are crucial. Rules such as stay in your assigned area, complete the assigned task and assist peers in your station would be critical for students to understand. Cooperative learning groups are the second topic that will be covered. This is similar to learning centers in that students would need to assist their peers within the group, stay in their assigned groups and complete the task assigned. However, another important rule might be to complete your individual task assigned. In cooperative learning groups, many times a large topic or task is broken down into individual jobs and these are assigned to each student who researches a particular topic and comes back to the group to inform them of their findings. The first out of class activity we will look at is field trips. Field trips are an exciting part of the learning experience, often times bringing to life what has been taught in the classroom. This is an experience that mandates students understanding specific rules of behavior. First and foremost, is the rule to stay with your group. Students need to understand the importance of staying close to your teacher/other authorized school adult so that they return safely. Another rule would be to behave appropriately as the environment calls. For example, a student would behave very differently visiting a library vs. visiting an arcade. Discussion on the location that the field trip takes place would be crucial. How one should dress, what noise level is appropriate and other topics would need to be explained to students. The next out of class activity is assemblies. An assembly is an activity that requires multiple classrooms and hence, differing age levels of a school to come together. This can be a situation that is ripe for negative behavior. There are many purposes for assemblies including special appearances of community members or other recognized individuals, or award ceremonies or special recognitions. Since most assemblies include the whole school, they tend to include large numbers of people and are often quite noisy. Rules that students would need to know include keeping a moderate noise level, walking in an orderly and appropriate fashion and keeping an eye on the teacher to know when to enter and exit an area. During the assembly ceremony, rules that need to be outlined include being attentive to the speaker and participating, if appropriate. The question arises of how we can accurately gauge a student’s understanding of behavioral expectations. The old adage of practice makes perfect would be appropriate here. For situations such as assemblies or field trips, a teacher could utilize practice sessions, coaching students on appropriate behavior in those situations, even having a mock assembly or similar activity to gauge how well students understand their responsibilities in that environment. The teacher could provide tips and tricks for the students to attend to such as always keep your eye on the speaker, which shows respect for the person giving the presentation. A more tangible method might be a multiple choice test given to the class. Depending on the age level of students, scenarios could be written asking students to circle the appropriate behaviors and cross out inappropriate behaviors. Rules and procedures are a vitally important lesson taught in classrooms. They are usually the building blocks of kids becoming productive members of society.

Strategic Management in Non Profit Making Organization

Introduction Strategic Management is the process by which managers make the choice of a set of strategies that will enable it to achieve better performance. The context of strategic management can be defined as the societal role of the organization, environmental, technological and human resource factors. With changes in a context, a unique set of managerial constraints arise (Stevens & McGowan, 1983). Context influences the nature of managerial behavior: the actions of a manager in arriving at a decision regarding how to deal with a given context.The way that a strategic plan is developed depends on the nature of the organization's leadership, culture of the organization, complexity of the organization's environment, size of the organization and expertise of planners. The not-for-profit sector is extremely diverse in terms of the organizations it encompasses and the work it undertakes. In recent years, there has been a substantial increase in the creation and consolidation of non-pr ofit organizations of various sizes, with diverse objectives and different scopes of action.More often than not, these organizations are managed by individuals who are dedicated or committed to the company's goals but have not had the opportunity to undergo specific training for this purpose. There are diverse types of non-profit organizations globally e. g. hospitals, social, cultural and political organizations. Most of the NGOs startups will usually come up with a strategy formulation paper which will consist of the vision, goals and objectives, implementation strategies and the budgets. This is because most of them are funded through grants and donations which will normally require a well done funds mobilization proposal. Related essay: â€Å"Support Positive Risk Taking For Individuals†However, most of them are less likely to engage in procedural strategic management implementation as a formal exercise. Also, these organizations are less likely to exhibit the features of a sound strategic plan as follows: †¢ Whereas one of the features of strategic planning is the long term nature of these plans, most of the non-profit organizations tend to be managed more on a short-term operational basis rather than in a strategic sense. †¢ Secondly strategy formulation takes into account the customers and competitor behavior.For nonprofit organizations, the influence of their clients or customers is often limited. These organizations will normally decide what is best for their clientele/customers and implement. †¢ Whereas strategic management is dynamic and continuous, most NPO aren’t very receptive to changes. They are comfortable in their current positions and transformation is quite an uphill task for them. Most of them thrive on tradeoffs between efficiency/productivity vis a vis processes. They are mostly driven by their social and community focus and appeal more to the conscience. This in turn stifles innovation and productivity and may hamper the decision making process. However, this will also be determined by the leadership style of the leader. . Requirements for strategic planning in non-profit corporate strategies Non profit organizations, just as for business organizations, can and should be designed to bring success and avoid failure. This can be done by capitalizing on the strongest capabilities of the non-profit organization in question, and exploiting the greatest opportunities, while reducing risk associated with organizational weaknesses, and environmental threats.This shared understanding of the overall strategic situation of the organization gives a sound basis for strategic decision making. The primary requirement for an overall non-profit or ganization set of strategies is that they should be developed to cover two main dimensions, bringing success and avoiding failure when things go wrong. †¢ Non-profit strategies must give the organization a very good chance of hitting the target for satisfactory performance and even exceeding it. †¢ At the same time, strategic planning nonprofit style must not expose the particular rganization to such risks that its performance might fall below to that considered to be failure. Additionally strategic planning in non profit must have a set of strategies that meet these requirements- †¢ Make full use of all the organization's most impressive strengths. †¢ Correct or neutralize all major weaknesses. It must not be based on these weaknesses. †¢ Either eliminate or reduce the impact of all the major threats. †¢ Exploit any highly rated opportunity for enhancing non-profit performance. Be strictly practical and relevant to the precise strategic situation of th e particular non-profit organization, and hopefully be †¢ Imaginative in the sense of being able to engage staff in implementation, and stand out among similar non-profit organizations in some way, and not be a pale imitation of what everyone else is doing, so as to strengthen the community standing of the organization and its non-profit mission. The following are some of the strategic contexts for non-profit organizations. (i) Governorship The not-for-profit organizations are not governed by organic law (constitutions).Top management teams are empowered by the corporate charter to engage in strategy implementation. A direct link between strategy formulation and implementation and the active involvement of all relevant parties throughout the process is deemed to be essential to effective private sector policy making. (ii) Openness to External Environment Not-for-profit organizations even though open to the external environment, the chief executives or board directors may ignore contributions into policy formulation and implementation processes from the various stakeholders.Failure to consider such contributions does not necessarily put their careers into risk, neither the legitimacy nor the credibility of the organization. (iii)Clearly defined goals Not-for-profit organizations generally operate within the framework of a limited number of relatively stable goals such as growth, profitability or market share. As (Peters & Waterman, 1982) noted, the top managements of more effective organizations appear to focus their attention on a limited set of clearly defined objectives. (iv) Cultural orientation Strategy formulation is largely affected by culture in non-profit organizations.Informal processes are used; for example an outstanding performer awarded a bonus in a not-for-profit organization is received well and does not attract bickering from other staff. (v) Human Resource Strategies In non-profit organizations, the personnel system is not based on merit. Employment, reward and advancement are done haphazardly thus creating a dependency relationship between the junior and senior staff. (vi) Separation of functional authority Not-for-profit organizations do not have a separation of functional authority like in the public sector.The organizations may be run by the directors who have founded them. The directors make day to day decisions and could even head departments in the organization. (vii) Marketing Strategies for non profit organization †¢ Website platform. †¢ Social media †¢ Brand enthusiasm †¢ Newsletters †¢ Creative Viral Programs †¢ Monitring. REFERENCES Peters, T.

A Clean Well-lighted Place Research Paper Example | Topics and Well Written Essays - 1000 words

A Clean Well-lighted Place - Research Paper Example The old waiter and the young waiter are expressing their individual thoughts regarding the deaf man’s habit of staying in the cafe for a long time. The setting in the story is a clean well-lighted cafe where a deaf old man is having his drinks. The setting in the story is crucial, as it reflects the thinking of the lonely old men who aim to escape from the world of darkness and despair. The views of the characters regarding the setting of the cafe have brought forth the theme of the story, which is the loneliness of old people. Characters’ mindset and cafe The story focuses on the plight of old men who are overwhelmed by the feeling of despair and loneliness, and how the cafe which is bright and clean provides comfort. â€Å"To the old man, the pleasant cafà © is his refuge, the place to which he can go to relieve his loneliness.† (Gerhard 5). The feelings of the deaf man are understood by the old waiter, for he is also experiencing similar feelings in his life. For both them, the cafe is a place which aids them to escape from the gloomy world of despair. Young people fail to realize the significance of well-lighted and clean place in the life of old people, battling with despair. The young waiter represents the thoughts of youth who are unable to comprehend the suffering of the old people. For the old waiter and the deaf man, the cafe is a source of succor and comfort. "He was in despair." (Hemmingway). They view the cafe from same perspective, for they are experiencing similar feelings. On the contrast, for the young waiter, the cafe is just a workplace. So he is eager to finish work and go to his house where his wife is waiting for him. The deaf man seated in the cafe and having drinks serenely, point towards quest for tranquility. â€Å"†¦he was a good client† (Hemmingway). He chooses the night time to visit the cafe, for he wants to avoid the crowd that would be present in the cafe during the daytime. â€Å"It gave him a sense of peacefulness.† (Brown). The deaf man’s wish to keep away from the eyes of other people is expressed through the seat he selects in the cafe. The deaf man is isolated from the society he is living in and even in the cafe he desires to be alone, enjoying the calmness of the cafe in the night. The interaction of the characters in the cafe provides an insight to their thoughts and attitude towards life. Contrast The contrast in the setting of the cafe and the world of old people aids in depicting the sorrow and suffering of the old people. The cafe is bright and clean whereas the house and world of the deaf man and the old waiter is full of darkness. It is this contrast that compels the deaf man and the old waiter to spend more time in the cafe than in his house. The brightness of the cafe brings light into the dark world of the deaf

Summary and reflection Essay Example | Topics and Well Written Essays - 250 words

Summary and reflection - Essay Example Even though the topic of the film was a contentious one, I found the movie to be insightful because I never considered some things to be racist. The most common one of these is when the white police officer manhandles a black woman on the pretext of possible drug use. There are many things in our daily lives that we do not recognize as being racist, even though many times they are. I most identified with Cameron, the husband of the black woman who was strip-searched, because he had to face a difficult dilemma. On the one hand, he could have prevented the police officer from assaulting his wife. The likely outcome would have been that he would be arrested. But, what he actually did was nothing at all. I would have done the same as him because police officers have the authority to do anything that they want because they are the law. I think that the director could have focused less on the divisions between white and black people because there are also many other cultures that can be racist. The characters in the movie were very stereotypical and I do not think that this helps ongoing racial

Literature ((BRITISH COLONIAZATION IN AFRICA)) Essay

Literature ((BRITISH COLONIAZATION IN AFRICA)) - Essay Example Goods that the British acquired from Igboland were spices, iron, palm products, timber, and elephant tusks, just to name a few. At first, the British were trading at the coast of Africa, but greed motivated them to make their way into Nigeria and take over the Igbo people, exploiting them and their resources in order to gain as much as possible (Litvack, "The Igbo People--Origins and History," 2001). The British colonization of southern Nigeria had a devastating impact on the Igbo people. For one, it caused the clans and the villages to turn against one another. Where there was once unity, there was now dissension, disharmony, and upheaval. Their once familiar way of life was now destroyed, never to be the same again. They were forced to adapt a new way of living, be subject to new rulers, and even adhere to a new religion, which was very much contrary to what they were used to. All of these devastating effects were what was responsible for the breakdown of the Igbo people, as well as the extreme loss of identity and culture (Litvack, "The Igbo People--Origins and History," 2001). Before the British colonists forced their religion upon them, the Igbo followed their traditional tribal religion. They believed in several gods who were led by one God named Chukwu. Chukwu was responsible for the creation of all things, and he was the leader of all of the minor deities. Chukwu was believed to be an almighty and powerful god who was omnipresent. Being that the people held this belief about Chukwu, temples, sanctuaries, symbols, and numerous representations of the god were all throughout the land. Aside from Chukwu, there were minor deities who competed amongst themselves. The minor deities each had their roles. Some punish people for offending the Igbo society, while others made sure people did not take advantage of their privileges. Then there were the gods who controlled the weather, as well as the growth of the crops (Litvack, "Religion and the Igbo People," 2001). Families and villages had their own gods that they adhered to, and each individual person had what was known as a Chi, which was a spirit that was returned to them at death by Chukwu. The Chi could either be good or bad. It was all dependent upon how the person behaved throughout life (Litvack, "Religion and the Igbo People," 2001). The Igbo also believed that the spirits of their deceased family members would watch over them to ensure that nothing bad came upon them and caused them harm. Because of this belief, it was common practice that the people prayed to the dead and asked them to ensure that they had a good and prosperous future. If anyone spoke against one of the deceased people who died an honorable or socially acceptable death, they were violating the law. Those who died in ways that the Igbo felt to be socially acceptable were who they considered as the good spirits that ensured safety and good fortune. That who died in a way that was not acceptable to Igbo society was considered to be the spirits that caused harm and upheaval. Deaths that were considered to be socially unacceptable were mothers dying during labor, babies dying before they had teeth, those who committed suicide and any who died during the sacred month. Multiple births were also considered disgraceful. For instance, if a mother concei ved twins or more, those babies were left to die

The Role of Japan of World War ll Essay Example | Topics and Well Written Essays - 1750 words

The Role of Japan of World War ll - Essay Example Japan started a war with China in 1937. In an effort to end the war of Japan against China, President Roosevelt shut off American trade with the Japanese, which made Japan more aggressive than before. The Japanese increasingly continued to look for strategic resources and raw materials southwards. However, the United States stood firmly, in Japan’s path. The United States pacific fleet at the Pearl Harbor was the only threat force with the capacity of challenging the Japan’s navy (Black, 2003). The American bases located at the Philippines also threatened the contact lines linking the East Indies and Japan islands. Every oil tanker heading to Japan had to pass through American-held Luzon. From these constraints, the Japanese war plans emerged. In analyzing this assignment, the assignment will discuss the role played by Japan in World War II. Based on this, background information on Japan that triggered the World War II will be discussed. In addition, the outcome of the war will also be discussed. Japan stood ready to overcome the whole South Asian Peninsula and the Dutch Indies, which was rich in oil. This planned conquer was as a result of Japanese lacking raw materials for its growing industries (Williams, 2005). The desire to conquer the Dutch Indies and the South Asian Peninsula angered the United States and an embargo developed between Japan and the United States. Negotiations targeted at ending the differences between the two countries failed since the countries were at odds with each other. The United States used force to make Japan withdraw from war against China and renounce alliance with Italy and Germany in 1940 (Williams, 2005). The Japanese were against the move by the United States; Japan was secretly planning an attack on the Philippines, Hawaii, and Guam. In 1941, the Japanese attacked the Pearl Harbor, which was viewed as a desperate action by Japan to escape from an earlier choice imposed by the United States.

Critical point Essay Example for Free

Critical point Essay Furthermore, its peculiar characteristics were also likened and even attributed to the psychological condition known as multiple personality disorder (MPD), because it assumes and behaves in two distinct phases, occurring as a high-density liquid or as a low-density liquid which was then normally thought to be quite impossible theoretically. The idea that water remains in liquid form even if it is in its super-cooled state when subjected to temperatures well below its ordinary freezing point (Introduction section, para.3-4), can then have a strong memory recall. Finally, simile was also used in the discussion of the â€Å"critical point. † A â€Å"critical point† was defined as the â€Å"set of pressures and temperatures at which a liquid changes from one form to the other† (Terms of Confinement section, para. 17). The critical point of water, or any other substance for that matter, was compared to the summit of the Mount Everest that â€Å"rises in a gradual manner and distorts the terrain all around it (Gaidos as cited in Stanley, Just a Phase section, para.6-8). † The interplay of logos and pathos, from which the blueprint of the author’s ideas was contained, was explored further in the way the article was outlined. It was divided into five parts, and with the exemption of the introductory paragraphs, contained four subheadings. The general idea was developed first before setting out to a detailed discussion. The title was catchy, as well as the subheadings and used colloquial speech to acquaint the readers to concepts that may be unfamiliar to them. This functioned as an expedient for logical arrangement, but more importantly, it meant to capture and retain the reader’s attention. The subheadings seemed to serve as an advertising ploy, operating on the stratagem of bite-sized packaging, to give the reader an impression of venturing in an uncomplicated, easy reading. For what could be the purpose of a piece of writing that supersedes the aim to persuade, inform or entertain other than to keep the reader reading. Persuasion, information, and entertainment work best when and if the author manages to contain the reader, from the first to the last paragraph of his/her work. In the course of the exposition, however, the use of scientific jargon and a technical writing style was more or less retained. The introductory paragraphs provided an overview of the article and the author began by discussing the properties of water, explaining how its molecules behave and how growing evidence reveal peculiarities in its nature. The succeeding paragraphs under the different subheadings elaborated on these matters citing the statements made and the experiments performed by noted physicists and scientists. In the last subheading, the article drew emphasis on the practical benefits posed by the integrated findings and hinted at exposing another set of data in the future that would add up to already established yet still growing collection of evidences. The shift allowed the article to maintain a credible tone and avoid appearing watered-down or downgrading to oversimplification. It was an effective synthesis of technical and informal language in journalistic writing, which proved useful in the sense that balance was made possible to be achieved in the logos and pathos aspects of the writing. The author was able to anticipate the needs of its targeted audience by giving them accessible grasp to scientific information, whereas not falling short on educating on a considerably theoretical viewpoint. Taken as a whole, to those who are rational enough to acknowledge that these discoveries were just products of scientific inquiry, this article might be seen on a neutral ground. The article was, for the most part, informative and there was no significant amount of persuasion leaning to any kind of ideology involved. It would leave the reader to extract any implication it might set forth during and after the course of reading and therefore enabling the reader to think for his own. Whatever the case may be, the author of the article cannot have the power to dictate how the readers may think, however unbiased or unprejudiced she may be in presenting the article. It is inherent in the topic itself to stir up ideologies, whether they are complementary or conflicting. On one hand, the facts that were cited in the article concerning the importance of the so-called weirdness of water in the environment and the ecosystem, even though, it may not be the similar case for everyone, might implicitly induce a real life pondering of thoughts among those who believe in why and how the water was created as such by their own notion of the Creator. This may have the capacity to strengthen people’s beliefs into considering that everything is really in the proper alignment and that everything is working perfectly however peculiar some things behave in the lens of scientific investigation. When a belief or even just an extension of that belief was affirmed by, in this case, research or scientific evidence, the tendency of the reader who in this sense is also the believer is to embrace that new piece of information and even so, when this information was delivered using simple words in a logical manner. On the other side of the coin, the emphasis the author placed pertaining to conducting further experimentations and intensive laboratory researches in the latter part of the article might also be alarming to some who might see it as man’s way taking control over nature and playing the role of a god.

Catching Fire Essay Example for Free

Catching Fire Essay â€Å"Without hesitation, he reads, on the seventy fifth anniversary, as a reminder to the rebels that even the strongest of them cannot overcome the power the capitol, the male and female tributes will be reaped from their existing pool of victors.†page.172, Catching fire. This is when Katniss finds out she has to go back into the arena and the fight the other victors. Some of them will be enemies such as the victors from 1 and 2. Some will be picked off immediately or just walk around like the morphing’s. Others will be allies such as nuts and volts or finnick. Finnick is an important character because he is brave, smart, and loyal. Finnick is brave in the arena, because he fights of the attackers at the cornucopia with Katniss on page 269 and 270. He also swam Peeta to shore which is brave because he was unarmed and vulnerable to attack. â€Å"Finnick has reached peeta know and is towing him back, one arm across his chest while the other propels them through the water with easy strokes.† P.273, Catching Fire. Finnick is also smart. In the arena on the beach he told them how to fish and find oysters on page 365. He also knew how to revive Peeta by giving him CPR on page 280. â€Å"Under Finnick’s guidance we spear fish and gather shellfish, even dive for oysters.†p.365, Catching Fire. Finnick is also loyal. He may not seem loyal but he still loves Ann even after all the people in the capitol hit on him. He also stayed loyal to Katniss in the arena even when she did the opposite of everything he said. â€Å"I see finnick†s green eyes in the moonlight. I can see them as clear as day. Like a cats, with a strange reflective quality. Maybe because they are shiny with tears. No he says I cant carry them both. My arms aren’t working. Its true his arms are jerk uncontrollable at his sides. His hans are empty. Of his three tridents one is left and it’s in peeta’s hands. â€Å"I’m sorry mags . I can’t do it.† Finnick is a brave, smart and loyal teammate. He didn’t kill Katniss, and saved peeta. He told them how to fish. He also let his mentor stay behind to be killed by the poison mist. He is a true asset to their team.

Critical Evaluation of the research methodologies

Critical Evaluation of the research methodologies 1. Introduction: In this report I have critically reviewed the methodologies which are used by Chevrier in her research paper. In this paper I have revealed whether she has used the correct methodology for her research or not, whether her evidence support her findings or not and I have mentioned an alternative methods to improve her conclusion. Chevrier paper aims at better understanding the dynamics of international project groups and she focuses on how project leaders manage the cultural differences to overcome and to use national cultures, ethnic diversity efficiently and effectively in the multinational project team. In her research she has depict three kinds of cross-cultural practices which were implemented by the project leaders. With these findings she has proposed a strategy to enhance the functioning of cross-cultural projects. I think the methodology which she has used in this research i.e. Case study is largely fine but not an effective one instead of this if she had used Grounded theory methodology for this research it would have been much more better research. I argue that the three case studies which she has chosen is not a typical one of all the multinational project groups. I argue that the Data collection technique which she has used in this research i.e. informal discussion is not a good technique to collect the data from participant. I argue that the strategy which she has proposed doesnt hold good for all types of cross-cultural project groups. 2. Literature review: Research can be a tricky, fascinating, awkward, tedious, annoying, hilarious, confusing, disturbing, mechanical, sociable, isolating, surprising, sweaty, messy, systematic, costly, draining, iterative, contradictory, open-ended process (Anthias, 2002) Methodology is identical to a research model employed by a researcher in a particular project, including basic knowledge related to the subject and research methods in question and the framework employed in a particular context (Sarantakos, 1998 cited Lather, 1992:87). Sarantakos (1998) relates the nature of Methodology to a theoretical and more abstract context, and perceives it in conjuction with distinctive, unidimensional, and mutually exclusive theoretical principles. Methodologies offers the research principles which are related closely to a distinct paradigm translated clearly and accurately, down to guidelines on acceptable research practices. Methodology is determined not by the research model but rather by principles of research entailed in a paradigm. Case-study research involves studying individual cases, often in their natural environment, and for a long period of time and employs a number of methods of data collection and analysis. (Sarantakos, 1998 cited Kromrey, 1986:320) 3. Critical Analysis of her Methodology: In this research the Methodology which is used by Chevrier is Case study. I think to do this research survey studies or experimental strategies will be too complex to implement, this is the main reason for Sylvie to choose Case study as the Methodology for this research. Generally case studies are done by a researcher when he/she is interested in the structure, process and outcomes of a single unit. (Sarantakos, 1998) Case studies are done by a researcher when he/she wants to extract data from a single field of study. Here Chevrier has chosen Engineering (i.e. three Project groups) as a field of study in which she has extracted the data and processed into information in which it will fit into the research topic. But this research topic demands to do study on all different kinds of field; but Sylvie hasnt done it, this is the main drawback of this research paper. In this research Chevrier focuses on how project leaders deal with cultural differences to surmount and even benefit from the variety of national cultures in their team. They have studied three cross-cultural practices that the project leaders explicitly or implicitly use to manage their international team and also studied the related outcomes from these practices. I think some methods and techniques which are used by Chevrier in her research paper doesnt holds good to the research topic. I think the samples(case studies) which she has chosen for this research doesnt sounds well because she has chosen only three international project groups to study the cross-cultural practices which are implemented in the team and moreover all these three project groups has the same background i.e. engineering. I believe just three project groups of the same background will not give a good weightage to her research paper. This is mainly because other than these three project groups there are different types of multinational project groups in which they are directly related to the cross-cultural management which I think she should have taken into this research paper. This research paper is pointing towards Multinational groups but the project groups which she has chosen has only people who are from European countries and Brasil, it misses out people who are from Asia, Africa and Australia. In this field work data is collected from Formal interviews, attendance to their meetings as a participant observer and informal discussions. I think the Primary data obtained from the formal interviews with project leaders and project members will be useful to analyse the data in this research and this data is important because the members of the project groups are the one who will be following cross-cultural practices and they will be knowing whether these practices are useful or not . In her research she has used participant observer as a data collection technique. I think it is a good technique for collecting the data in this research. Since her team will be a part of the cross-cultural group so they can observe easily how the team members/managers will behave and whether they are following the cross-cultural practices or not. They have attended even meetings to collect the data I think this is the place where they might have got a good data because this is a place where they can observe whether the managers and leaders are following cross-cultural practices or are they giving any importance to it or not. Chevrier and her team was also present daily among the project groups particularly for project 1(for 2 project weeks) and project 2(for 2  ½ months), I think daily presence in a project group is important because generally people wont behave same way in every time/day and also we cant judge their behaviour on cross-cultural practices in a single day. So daily presence in a project group will give a good data for the researcher but interesting point in her data collection is she or her team was not present daily for project team 3 but they were present only in project team 1 2 and that to in project team 1 they were present daily with team for just 2 ‘project weeks, so I dont think within these 2 weeks they have collected a strong data because in just 2 weeks it is less practical to summarize their behaviour. I think the primary data which they have collected in project team 2 will be useful because for 2  ½ months they were daily present with the team so with this time they will be in a better position to judge their behaviour with respect to cross-cultural. I also think that the Informal discussion which she has used in this research is not an effective technique. I agree this technique partially and I also disagree partially. I think this technique should be used depending on the situation in the working environment; if the working environment is not so good then there is no use of having discussion with them because the interviewee may give answers simply just to pass time. I think they should use only when the team members are in a good mood and moreover this discussions will take place mainly during lunch time of the employees, this is the time where most of the employee will relax, spend time with their colleagues and chat with them, if Chevrier and her group starts to discuss with these employees then most of them wont be interested and they will just say something or they will give less answers so that the discussion will be over fast. She has analysed the collected data by Cutting of Tran scripted interviews and meeting notes by theme. She has prepared a monograph for each and every theme which I think its a good idea and it will be useful for comparing all the themes. This type of comparison will help to find out the common and uncommon features of all the cases 4. Will her evidence support her findings? I think the evidence which she has used in Case 1 will support her findings. This is a project group of European consortium set up to make RD in the telecommunication industry. The contract which is signed by these companies designates one company as a primary contractor which will appoint a project leader among its engineers. We know that the newly appointed project leader has no hierarchical authority over the other partners due to this he/she cannot demand anything from other partners, infact he/she cant expect that other partners will involve totally (100% commitment) in this project and there is also a possibility that this may also lead to lack of institutional management with the other partners. In this project the leader has to take some technical decisions in which sometimes it may not be accepted by the other partners as she found this from Northern Europe and especially from Scandinavia that they only speak up when they disagree with what is being said. These project groups were not totally involved in the project. In this case the project leader has no choice he has to tolerate with these kinds of partners. This is what Chevrier has found that the leader explicitly or implicitly relies on tolerance of team members to surmount difficulties. The project group (RD consortium) has people from different countries; definitely all of them will have different opinion on Cross-cultural activity. Some may tolerate the diversity and some may not. Chevrier has found out different opinions from the interviewees e.g. In multinational teams some team members tend to forget the nationality of their colleague to focus on technical issues. Oppositely, the second part of interviewees says that they make their best to struggle against prejudices, stereotypes and ethnocentrism. In the 2nd case of Chevrier it is said that the greatest difficulty for the project manager is to make the work required for his own project a priority for team members who are very much in demand. If this is the case most of the manager tries to protect his team members to work in his project because every manager will have some task to complete, so to do this task without skilled workers in his team it will be difficult for him to complete it. If the manager couldnt maintain these workers in his team then there is every chance of showing less interest in the project. This is what happened to Swiss manager as it is told in Chevrier paper that â€Å"Swiss manager straightforwardly declared he did not want to make any difference and was careful to manage all team members the same way.† Chevrier has also backed up this argument by giving the reference of Laurent (1998), â€Å"we observed that when managers encounter cross-cultural differences, they often do nothing and consider that it is legitimate not to talk about them.† In case 1 the main job of the project leader is to maintain a strong institutional management with the other partners. Since the leader doesnt have the hierarchical authority over the other partners it will be difficult to manage all the other partners. His main job is to get the task done, since he doesnt has the upper hand over other project members it will be difficult for him to give orders for other groups to complete the job. In chevriers research, for this problem she has founded that â€Å"developing personal relationship with one another in a team will set up working arrangements more easily. If they know each other very well, it will help them to become acquainted with one other†. This strategy will suit only for RD consortium project group because in this project all its partners doesnt know each other so this strategy may enable effective mutual agreements between all the partners. But it doesnt suit for Electrical engineering project infact it can reinforce negative stereotypes and polarization between cultural groups. This is true because in this project the Swiss manager straightforwardly declared that he did not want to make any difference and was interested to manage all team members the same way, if this strategy (developing personal relationship) is implemented in this project group it may result in other way because due to less involvement by Swiss manger there is a more chance of negative stereotypes and polarization between cultural groups. This may lead in such a way that project may not complete. The strategy which is proposed in this paper by Chevrirer (cultural mediator) suits good for some multinational project groups but for some project groups it doesnt. Since in this strategy cultural mediator has to invite the project members quite regularly to find out the exact problem, this is possible only when all the project members are meeting together quite regularly at some place but this strategy cannot be applied to some multi-national groups where the project members wont meet regularly. However, in a multi national group most of the time the project groups will be from different countries so it is not practical to implement this strategy because all groups are from different countries and also it will be difficult for all the members to attend the meeting if it is put up by cultural mediator. As we can see in RD consortium group all the team members meet each other only four or five times a year. During these weeks all the project members will be busy with other partners about their plan and objectives in their project. So if this strategy is applied to this group then cultural mediator will not find sufficient time to spend with the team members to talk about their problematic situations which have encountered. I think this strategy can be applied to the project team in electrical engineering because this team is composed of a project manager, engineers who are all located in a single building but in a different floor. In this team cultural mediator can easily set up a meeting with the team members and find out the problematic situations which have encountered. Even in the product development project have subsidiaries which are located in different countries such as Germany, France, Belgium and Italy and co-ordinating the development process is in charge by ‘‘central group which is located in the French subsidiary. So even in this project group cultural mediator will find difficult to set up a meeting to talk about their problematic situations which have encountered. I think she has not justified all the problems which will occur in the multinational group. For e.g.— Race can be a problem in the group. Merriam et.al. in their research has found that â€Å"Racism was the specific dominating factor in cross cultural groups†. Color As an issue of concern amongst Blacks, colorism is examined and debated in Black communities in a less than open manner. This intraracial discrimination among Blacks gives preferential treatment to those who have lighter skin shades. (Merriam et.al) 5. Alternative Methodology: I think Grounded theory analysis will be a better approach for this research because in this research topic we need to analyse more number of case studies, interviews and observation so I think grounded theory will be the best methodology for this research. Another reason for using grounded theory techniques is â€Å"Grounded theorising is well suited to capturing the interpretive experiences of owner/managers/employees and developing theoretical propositions from them.† Rowlands B. (2005 cited from Strauss Corbin 1990) From the above reason we can say that, Since Chevriers research is related to the cross-cultural practices which are followed by Leaders, Managers, and Team members, so this methodology will be very useful in gathering and analysing the data. Similarly, Grounded theory has been effectively used in recent Information System research to develop theory of Information System practice. Rowlands B. (2005 cited from Urquhart et.al., 1997) In choosing the International project groups Chevrier has chosen the groups in which all groups has the same background i.e. Engineering. Instead of choosing three project groups from a single background she could have chosen three project groups from different fields. Because choosing a sample project group which is typical to that environment is very important and the data collected from this typical one will bee much stronger than the data which she has collected from the three Engineering project groups. I think Ethnographic interview will be useful to get valuable data from the interviewee. The main aim of this type of interview is to study the Culture of the people and to find out how it will impact on the people behaviour. â€Å"It aims to discover or understand the culture of people in their social environment and of explaining the social justification of their role and position in that culture.†(Sarantakos, 1998). This interview would have helped her in finding the culture of the project members/leaders and based on her understanding on their culture she could have compared with the Cross-cultural practices which were implemented by the management and she could have got a better result. If Chevrier had used all the above methodology in her research, I think this would have improved her research conclusion. 6. Conclusion: In this paper I have revealed that the methodology which is used by chevrier for her research is not a good one. I have shown that some of her methodology which she has used is not effective with respect to the research. The three case study which she has chosen in her research is not a typical one because all the case studies had the same background i.e. Engineering, instead of that she could have chosen case studies which are from different background and I also showed that the data collected from participant observation in project group 2 was strong. I showed that the data collected from informal discussion technique was not good. This paper reveals that Ethnographic interview and Grounded theory would have helped her to collect the strong data and to analyse the data which she has collected. I have shown that up to what extent of her evidence will support her findings. In this paper I have also concluded that her proposed strategy will holds good only if all the project members/g roups are in the same company or at least in the same country, it doesnt suit if all the project members/groups are in a different countries. 8.

AIDS Prevalence and Awareness in South Africa :: AIDS HIV Disease African Essays

AIDS Prevalence and Awareness in South Africa Johannesburg, the largest metropolitan area in the continent of Africa. The population of the main metropolitan area is 1,907,229 ( WorldBook encycl.130). Johannesburg is also one of the world richest gold fields. Despite these positive aspects, Johannesburg is a city with a dismal future, because it is suffering from one of the world's worst AIDS epidemics. Every Saturday, nearby cemeteries are busy with the arrival of people who have died from AIDS. Funeral directors state that about 30 or 40 people are buried every week, as a result of AIDS. It is said that in South Africa, one of every ten people has AIDS. Some 17 million people in Africa have died representing almost 80% of AIDS deaths world wide. This is the equivalent of the combined populations of New York City and Los Angeles (www.Time/2001/aidsafrica). There is a conspiracy of silence fueling the spread of HIV in South Africa. Johannesburg is the largest city in South Africa, and has one of the fastest growing infection ra tes AIDS is now South Africa's leading cause of death. Last year it accounted for 40% of all deaths between the ages of 15 and 49 (US.news2.yimg.com). By the year 2010, HIV prevalence in adults is projected to reach 25% of the total population. South Africa is projected to have the highest AIDS death rate until 2015. At that point, the population will have decreased to the point that the death rate will no longer be as high as in other areas. South Africa has a population close to 40 million people - an estimated 4.2 million (10.5%) are infected with HIV. Of these, half are women ages 15-49. Over 40% of pregnant women are HIV-positive. The impact of AIDS in South Africa is overwhelming. The disease has orphaned 370,952 children 95,000 children have been infected with AIDS. The adult prevalence rate of HIV is 20%. While there are limits in extrapolating the general population, it is estimated that 4.2 million people were HIV positive in 1999, compared to approximately 3.6 million in 1998. (www.securethefuture.com). Statement of Need: Understanding who is Affected by AIDS Demographics show that those most affected by AIDS are women and children. African women and children have been particularly hard hit by AIDS. There are now 16 million African children who have lost at least one parent to AIDS. Johannesburg medical agencies state in their reports that in the next 10 years, that number will reach 28 million.

Bowing to Seniority :: Documentary Journalism Sports Basketball Papers

Bowing to Seniority With the dearth of good centers in college basketball, one would expect that Xavier University would want David West, their All-American center who averaged 20 points and 10 rebounds per game as a junior, to return for his senior season. But West did not feel so welcome. â€Å"Honestly, it felt like they wanted me to leave,† West said. â€Å"Not Coach [Thad] Matta specifically, but most people seemed to be pushing me out the door [to the NBA].† Eventually, West decided to return for his senior season, and then became part of a dying breed: college seniors who get drafted in the first round of the NBA draft. In the last two NBA drafts, high school players and college underclassmen outnumbered the college senior first round picks 19-13, with only four college seniors going in the first round in the June 2004 draft. In 1999, 13 seniors went in the first round. The number of lottery picks (teams who do not make the playoffs, the first 14 picks of the draft) shows the disparity more clearly with more underclassmen being drafted in the lottery by an 11 to 5 margin. Before the New Orleans Hornets took West with the 18th pick of the 2003 NBA Draft, he had a successful senior season at Xavier, where he was an All-American and the Associated Press Collegiate Player of the Year. As little as eight years ago, West probably would have been a top five pick; as prospects were still valued more for their ability to contribute right away rather than their â€Å"potential.† But because of what Mississippi State University Coach Rick Stansbury calls a â€Å"disturbing trend,† that of underclassmen entering the draft with greater and greater frequency, West fell completely out of the lottery. Some argue that the slide through the draft of seniors like West has to compete with not only the increase of college underclassmen entering the draft, but also international prospects who have the â€Å"upside† to be superstars, even though many teams have seen very little of them actually play. However, West does not think that the international players have affected the draft that much. "If you can play, you can play," said West. "I'm not worried about what (European) guys can do. American guys have shown what they can do. In the end, if you can play, they're not going to let you go." Over the past 10 years, the mindset of the NBA prospect has changed.

Hatchet :: essays research papers

Hatchet’ Speech.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬ËœHatchet’ by Gary Paulsen is a great book about survival in the wild. It follows the time of a boy, Brian Robson, who crash lands in the middle of a Canadian forest. I think Brian would have though of his time in the forest as fulfilling. Maybe not in the middle of the story, but afterwards, he would of thought of it as a very good experience. From only pages of the book, Brian starts to learn. When the pilot offers him a quick ‘lesson’ of flying the Cessna plane, this saves his life when the pilot dies a horrific heat attack in his seat. This causes Brian to panic, but he safely crash lands inside a lake. Then soon after, he starts to learn that just some insects are coming wanting his flesh. He never thought they were that bad until they cause him to swell all over The only stuff Brian had seen about the wild was on nature films â€Å"They only showed animals jumping around in the bushes and the rolling mountains†. It said in the novel. Brian had only lived in the city, where he is hidden away from the wilderness. He had never been into a forest before. So he was living by what he knew, which was very little. When he goes looking for berries, he is confronted by a big bear. He had seen one before in a zoo, and thought that they would be something to stay away from in the wild. He thinks he is done for, and thinks he will be attacked. But the bear leaves him alone, leaving him with the thought that they only attack you if you attack them. He learns things that are not just relevant to wilderness survival but also about life. These include patience, appreciation for the natural world and observation. He learns to control his temper when he discovers frustration and hopelessness does nothing. He also learns by trial and error, like hunting or building his shelter. For example, his first shelter doesn’t work, so he spends more time on building the second. If a method fails to accomplish the job, Brian learns from his mistakes instead of dwelling on them. Brian also notices the beauty of nature and its sights and sounds. Living in the city has dulled his senses. He uses his new senses to survive, like when at first he couldn’t locate the foolbirds he tries to hunt, they pop out of nowhere surprising him with their presence.

Baroque Art Essay

It’s hard to make a distinction in which the beginning of the Baroque period is clearly distinguished from that of the late Renaissance. Nonetheless, Baroque art is emotional, decorative and a direct result of the Counter-Reformation movement in Europe. During the Baroque period, there was a dramatic religious split in the Church with the formation of Protestantism. Catholics reacted with the Counter-Reformation to revitalize Catholicism. They needed to attract viewers with religious art that more significantly impacted onlookers. Protestant areas (in the North) responded with a lack of religious art, concentrating, for example, on genre paintings that taught their viewers moral lessons. Compositions tended to have more open space. The Baroque style originated in Italy and spread north, profoundly affecting the rest of Europe as it spread. In his survey of art history text, Gardner’s Art Through the Ages: A Global History, Fred S. Kleiner asserts that the term Baroque is â€Å"problematic† because the era encompasses a broad range of genres and styles. At the same time, it is effective in describing the art of the 17th century, a style marked by dynamism and movement, drama and greatness. Since the masses could not read, there could be no better way to feed them religion-Catholicism’s particular view of it-than through grand pictures depicting Biblical lessons and the dominance of Catholicism, figured the Church. One of the most interesting examples of art as propaganda for the Catholic Church is Caravaggio’s Conversion of Saint Paul, painted ca. 1603. In 1600, Caravaggio was commissioned to paint two pictures. One is Crucifixion of Saint Peter, a dramatic and unconventional work. The other is Paul’s Conversion, which hangs across the chapel from Saint Peter in the church of Santa Maria del Popolo in Rome. Also known as Conversion on the Way to Damascus or The Road to Damascus, this depiction of Paul’s conversion is known as the most intriguing of the two paintings. In this grand picture Caravaggio portrays the moment described in the Bible, in the Book of Acts, when Paul (then Saul) falls to the ground in an epiphany from the Lord. The egocentric, Christian-hating Saul is on his way to Damascus, on a mission to witch-hunt Christians there. In Acts chapter 22, verses 6-7, Saul describes the moment: â€Å"About noon as I came near Damascus, suddenly a bright light from heaven flashed around me. I fell to the ground and heard a voice say to me, ‘Saul! Saul! Why do you persecute me? ‘† This information is important to consider when studying Caravaggio’s representation of the event. Caravaggio, who, in his personal life, was known to have an erratic disposition and not long after painting this scene, he fled Rome after killing a man (Encyclopedia Britannica) clearly was a revolutionary in his art. In this scene’s it perhaps showed the mystery in the man that represents Caravaggio’s sarcasm, his sardonic version of Jesus, who, after all, is the one who knocked Saul senseless. If so, what is it that Caravaggio is secretly saying about Jesus? We will never know, but the possibility is at least entertaining. Summary While Baroque art arose out of an effort to manipulate the masses through propaganda tactics, it changed and evolved as it spread throughout Europe. Today, the style can be appreciated for its many accomplishments, everything from its realistic renderings to its grand drama and its larger-than-life grandeur. Baroque art has an intensity and immediacy not seen prior. The exquisite attention to detail and the realism of the style are part of what defines this age. Many masters emerged from this era, masters whose styles are widely varied and whose intentions were just as varied, and much can be learned from them and the legacies they left behind in their art, music, literature and architecture. Combined, these characteristics make the Baroque style one of the most compelling periods in the history of Western art.

Giant Panda and Wildlife Conservation Essay

Wildlife conservation is the most important things in the world. And people have made a lot of progress in this field. In wildlife conservation, people try their best to protect endangered plants and animals, as well as their habitats. The purpose is to make sure that future generations will have enough space to survive and develop well. Countries all over the world have different agencies for wildlife conservation and plenty of nonprofit organizations also take part in the process of this activity. Various kinds of subjects are involved in the process of wildlife conservation. For example, people must use the knowledge in the field of biology and other sciences to recognize the species that are in danger, and to study those species to learn more about their needs. Economics is also involved in wildlife conservation, because the conservationists are trying to find out the most efficient solutions. Apart from these, the protection of wildlife also depends on education very much, using different methods to teach people about the importance of animal habitat conservation. However, the Earth is warming, and humans are using more water than ever before. It is important to know how people save wildlife around the world especially conservation in China, the U. S . and then when happens after conservation especially the government’s role in the process to protect wildlife, as well as the effects of these measures. Conservation in China China has a vast variety of species, with the number of mammal species ranking second all over the world. In terms of reptiles and amphibians, China’s ranks are the fourth and sixth respectively. Although China only ranks eighth when it comes to its bird species, there are still about 1,244 types of birds in this country. A lot of these bird species are native to China, and that is why China has the responsibility to protect their future existence. There are sixteen primate species living in China. However, in the northern part of the tropical area, China has precious species such as the Sichuan golden monkey, which can also be found in Hubei as well as Sichuan provinces, and the Yunnan golden monkey, which lives in high-latitude places covered by snow of about 4,270 m. (Harris, 2007).. Golden monkeys, tigers, and pandas are rare and protected animals in China. In China, however, the most famous endangered species of wild animal is definitely the panda The panda is an endangered species of wild animals, and it can only be found in China. So people can say that panda is China’s unique wild animal, so the protection of this animal is essential. The habitat of pandas lies in the provinces within China’s â€Å"Great Opening of the West†. The place is so fragile and unique that people can only run tourism on a small scale as the only economic activity. Therefore, it is extremely essential to create more nature reserves for the protection of pandas, even though some of them are not working effectively. If we do not pay most of the attention to allocating these areas as habitat for pandas, these places will definitely be used for producing wood and or agricultural crops. Recent survey in 2004 found that many threats including deforestation and persistent poaching interfere with the long-term survival of this endangered species. (Harris, 2007). For instance, Western development for pandas makes Chinese poachers see business opportunities and their harmful behaviors have seriously affected the survival of this precious animal. Human development has affected wildlife survival environment. Because of the population explosion and unsustainable use of natural resources, the panda habitat is also rapidly losing. Pandas adhere to living in a large area of natural forests, which can also be used for agriculture, timber and firewood. Because of China’s dense population, many of the giant panda population is isolated in no more than 1093-1312 yards wide narrow belt of bamboo. Because of immigration, the panda’s habitats are continuing to disappear. In more than 20 pandas range, there are many habitats fragmentation into isolated areas. In these areas, a network of nature reserves exist to protect more than half of the panda population. Because of the requirement for habitat, the giant panda cannot migrate, so they have lost a lot of flexibility as they are not able to find new feeding areas. (Calhoun, 2005). In China, humans’ over-exploitation of trees and the destruction of environment have also caused a large number of pandas to disappear. Moreover, China has no ability to build adequate reserves to protect the panda. Conservation in the United States America is a country with a focus on animal protection and people there treat animals as their close friends. The country of United States has a broad geographical location and there are many kinds of views in the United States, from the polar ice to tropical rain forests, from moderate rain forests to prairies, from mountain summits to desert and coral reefs. There are some places to live, comprising the most richest land on the Earth, such as the lower Mississippi River and the western salt marshes which are some of the most barren areas. Wonderful and various kinds of animals live in many places of this country, such as elk, wolverine, bison, grizzly bear, bald eagle, musk ox, caribou, wolf ,mountain lion, polar bear, and moose, which are booming in these areas. It is also the habitat of thousands of amphibians, fish, bird and reptiles. (â€Å"Wildlife Conservation Society,†n. d. ). Americans attach great importance to the protection of animals and people in the United States to give animals a lot of living space and a good natural environment. In order to ensure the survival of wildlife in the United States, people have founded a vast area of nature reserves. In terms of conservation innovation, the U. S. has a rich history. The U. S. created Yellowstone, the crown jewel of parks in 1872, establishing the concept of national parks. And then in 1932, the first International Peace Park, Glacier-Waterton National Park along the border with Canada was created. Even with a vast system of public lands which provides protection for the wild places in the country, including national parks and wilderness areas for fishing and wildlife refuges and state lands, there are still some conservation challenges caused by management activities on the public lands. Usually, more efficient private lands are a vital component of long-term success in conservation. (â€Å"Wildlife Conservation Society,†n. d. ). The Yellowstone national park is one measure to guarantee the protection of their animals, since the place gives wildlife enough living space. Yellowstone national nature reserve gave wild animals more opportunities and space. People also try their best to protect wolves in the United States. In March 2003, the U. S. fish and wildlife service issued a rule, significantly reducing federal protection for wolves and set the stage to liminate them from the endangered species act (ESA) protection completely. Until now, in terms of the recovery in the number of wolves in the 20th century, the U. S. fish and wildlife service has done a great job. People take wolves into the Yellowstone national park and central Idaho. This protection is considered by many to be one of the great achievements. (Calhoun, 2005). The United States fish and animal protection administration also obtained remarkable achievements in protecting the wolf population. After Conservation After the management of protection on animals by volunteers, the joint efforts of the China panda protection finally result. Recently, the world natural foundation has helped the Chinese government in the field of national habitats of giant panda and its protection program. This program has made significant progress: China now has 33 of the giant panda reserves, and the giant panda habitat reaches around more than 6177 square miles of area. According to a survey in 2004, there were 1600 pandas in the wild. (Calhoun, 2005). With the help of the animal protection association of America and China, multiple reserves are established. China needs more reference to the United States in protecting wild animals. Wildlife protection is the responsibility of people around the world. Chinese and Americans need to learn from each other about how to protect endangered wildlife better in the future. China should, for example, learn from the United States some new ideas of animal protection and the responsibilities of ordinary people when it comes to animal protection in the wild. Through the study of wildlife conservation concept, people in China can improve their animal protection measures, reduce cutting down trees and causing environmental damage any longer. Strengthening the reserve management and reducing the poaching practice, these measures will better protect endangered wild animals. The United States in the field of conservation philosophy occupies a leading position in the whole world. For instance, American people created Yellowstone national park and the international peace park. These huge areas provide plenty of living space for wild animals. China also has an extensive area, so there are a lot of important lessons China can learn from the United States, such as creating national parks and nature reserves in the areas which are suitable for specific kinds of animals. In the meanwhile, if necessary, China may also seek some help as well as advice from the United States. Conservationists work all over the world. To determine the species need to aid and protect them. The subject usually include animals and raise them. Capture prisoner ensure still large and diverse population at the same time environmentalists work establish territorial animals, so they can have a safe place in the field. Wildlife conservation needs also need to be balanced with other desires, because many countries value forms of entertainment like hiking in the wilderness, camping, hunting and makes it impossible to set aside land makes wild animals live. In this respect, China only attaches great importance to the development and demand of human beings. Ignored, the environment and wild animals, and other important factors.

Organ Donation Essay

Organ Donation The process of taking functional organs and tissues from one person for transplantation into another individual is called organ donation. Whereas, any part of the body that performs a different and special function is referred to as an organ. Transplantation takes places quite successfully today between well-matched human beings. Majority of the organ recipients are able to live five or more years. Skin, cornea, bone marrow and kidney transplants are the most common today. Moreover, lung and heart transplants are also gaining precedence. In commonplace terms, organ donation is the removal of working, healthy organs from the body of an individual who had pledged while being alive that his organs could be donated to a person requiring it. Usually the tissues or organs are taken out in a manner similar to surgery. Moreover, all the incisions are clogged at the end. Organ donors can include people of all ages. It is not restricted to any particular group, nor is it restricted to any cert ain age limit. In the present era, organ transplantation is widely recognized as of the most gripping medical advancements. It is almost the elixir of life to individuals with deteriorating organs who require other fellow beings to donate them organs. With the increasing cases of organ failure in society and the insufficient supply of organs, there is an enormous gap between organ supply and organ demand. Subsequently, it takes ages for a person with deteriorating organs to get functioning organs from another being. Moreover, numerous deaths have been reported in that waiting. Thus, these events have aroused moral, societal and ethical concerns regarding the allocation of organs, supply and the use of surviving donors as volunteers,  including those who qualify as minors. Unfortunately, it has spurred the practice of selling organs by money-makers for their own monetary gains and vested interests in many parts of the world by exploiting the poor. This has spurred corrupt practices where organ donation is concerned (Shroff, 2009). While we are on the subject of organ donation, an ethical issue is the procurement of organs and tissues. Firstly, this includes the buying and selling of human organs and tissues: There are some people who believe that human organs and tissues ought to be bought and sold in order to quantify the supply and show deference for other people’s autonomy. On the other hand, there are people who believe that treating any part of the body like a saleable good is a violation of human dignity. Organ donation has evolved considerably in the last 50 years. Following is a history of the procurement of organs and tissues. †¢ Successful transplantation of various organs Initially, organ transplantation started with kidneys, but now it has diversified to lungs, livers, hearts and other organs. It has slowly evolved to encompass various parts of the body. Progress in organ donation and cadaveric practices To decide who can donate organs has been a continuously evolving process. Firstly, it started with living donors and later moved on to include dead and brain dead donors. Even today, there are debates about growing and limiting the qualified donors. In the year of 2001, the surviving donors managed to even outnumber cadaveric donors. This was a milestone in the history of the United States. Formulation of anti-rejection drugs to enhance development and success The formulation of anti-rejection drugs has compounded the success of organ transplants. In the 1960s and 1970s, immunosuppressant drugs were used to increase the success rate of organ transplants (Flaman, 2008). Cyclosporine was stumbled upon in the 1980s. It greatly improved the success rate for patients undergoing transplants. The overall results were also improved. A phenomenon called xenotransplantation also became well-known – this entails the usage of animal organs for human transplantation. Subsequently, the firs t xenotransplantation was conducted  in 1986. This breakthrough means of transplantation started gaining popularity and researchers started performing more intensive studies on it. The number of people who required organ transplantation started to multiply. The discovery of the first artificial organs In the 1980, the first artificial heart transplant took place which was followed closely by the American public and the news media. This basically involved segmenting organs into pieces (either from cadaveric donors or surviving donors). In 1996, the first split liver transplant too place. It permitted one cadaveric liver to be used among several patients who required a transplant. Stem cell research: This basically involves the examination of human embryo and adult’s cell in an endeavor to find out how organs are development and what stimulates their development. There are certain ethical concerns regarding how organs and tissues are obtained. For instance: a pharmaceutical company in France buys placentas from 110 Canadian hospitals in order to produce blood products and vaccines. However, there are some poor people in countries, such as India, who sell their kidneys for $700 or even more than that. There have also been cases reported in India where people have gained consci ousness after a kidnapping incident, only to discover that one of their organs has been removed in that process (Caplan, 2010). In regards to this issue, there are people who draw a difference between waste matter of humans, certain body parts that happen to regenerate such as blood and non-regenerative human organs such as kidneys. There are many people who differentiate profit making from covering the donor’s expenses. If a donor has to pay for organs, this can put undue pressure on him. It nullifies a contract or free consent. There are some people who are also fearful of the fact that if the buying and selling of organs became a notorious business, then it would undermine the nobility associated with organ transplants. It could be detrimental if the organ just went to the highest bidder. The equity would be compromised upon as donating organs would depend upon the ability to pay rather than finding out how they should be distributed. There are some people who argue that this can be brought under control by monitoring sales. If the buying and selling of organs and human tissues is completely restric ted, then it would drive the market underground. Since there are numerous controversies associated with  the buying and selling of human parts, there are many who believe that other alternatives should be adopted (Thomas, 2009). Media Publicity There are several instances when an organ or tissue is acquired for a person by showcasing their need through the media. This could negate the other transplant channels through which it is normally obtained. Moreover, the correct criterion of selecting recipients, which is usually done on the basis of greatest needs and greater likelihood of benefit, can also be overlooked. However, publicity through media creates awareness in the public domain about the need for transplants and in the long run will increase the supply of organs and tissues. Voluntary consent basically entails a person making an intended offer to donate their organs after their demise. In the case of cadaver donation, a person can intimate their consent by advanced directives, such as by filling out the Universal Donor Card, part of their driver’s license. When the transplant is from a living donor, free consent is necessitated. However, it is best to have established consent regarding a deceased donor because this act exhibits love and responsible stewardship over one’s body. Moreover, it also communicates the wishes of health care professionals and family to the individual as well as others. When there is no pre-existing consent, the person who holds responsibility for the dead body should be approached regarding donation. It is imperative that the wish of the deceased person should be upheld. Medical ethics in organ donation has become imperative. This is basically a system comprising of moral principles that applies judgments and values to the process of organ donation. Autonomy is the sole prerogative of the individual to choose what happens to him/her even if this means dying in the process. In this regard, even if a person wishes to contribute his organs to another and thus die, he should not be prevented from doing so. On the other hand, fidelity entails adhering to the choices of someone, even if paying no heed to them would save another person’s life. Confidentiality means protecting the names of the donor from being let out in public or as per the desire of the patient. Hence, if a person prefers to remain unnamed while consenting to donate organs, his wish should be upheld. The team performing the transplantation can ask questions, but foremost it is imperative to prioritize the desire of the patient over anyone else (Truog, 2005). In order to address the ethical issues associated with organ donation stated above, it is important for health care professionals to be acquainted with the meaning of organ and tissue donation. They should be well-versed with the procedure of organ donation and to perform it in the best and most efficient manner possible. It would also be a good idea to render training to members of the health care team so that they can approach potential donors and families in a sensitive manner. To facilitate the process smoothly, they should be able enough to provide the necessary social and personal support during the process of mourning. Providers of health care also need to learn that respecting a dead person is a prerequisite of our humanity. It is also pertinent to mention that any reference to the deceased should be done with utmost sensitivity and using the most appropriate names. Furthermore, to compound the potential for transplants, providers of health care have a fundamental duty of rai sing the general level of awareness of needs. It should be done in a way that protects the rights and privacy of the patient, does not tamper with the medical process in any way and also does not remove attention from other urgent matters (NHMRC, 2012).

Esr Experiment

Electron Spin Resonance Tabish September 2003 Aim: To determine the Land? g-factor using Electron Spin Resonance. e Apparatus: ESR setup which includes Helmholtz coils, R. F. oscillator and the test sample, and in addition, a cathode ray oscilloscope (CRO). Theory Background Suppose a particle having a magnetic moment  µ is placed in a uniform magnetic ? eld of intensity B, then the Hamiltonian can be written as ? H=g e ? J  · B, 2mc where g is the Land? g-factor, which is 1 for orbital angular momentum, and 2 for spin angular e e? h momentum.The factor 2mc , sometimes written as  µB , is called Bohr magneton, if the particle in question is an electron. If the particle is a nucleon, then the factor is called the nuclear magneton. If the angular momentum J results from a combination of an orbital angular momentum and a spin, then g would be given by the Land? formula: e g =1+ j(j + 1) + s(s + 1) ? l(l + 1) , 2j(j + 1) where l, s and j represent the magnitude of the orbital, the spin and the total angular momenta, respectively. Remember that j can go from l ? s to l + s. Conventionally, the static magnetic ? eld is assumed to be pointing along the z? xis, which modi? es the above equation to e ? ? Jz B. H=g 2mc Let us now consider an atom which has an electronic ground state with total angular momentum j = 1/2 and an excited state with j = 3/2 (see ? gure 2). There is only a single transition which can be induced by the absorption of radiation of frequency ? 12 = (E2 ? E1 )/? . As the energy does not depend h on the angular momentum states, the ground state is doubly degenerate corresponding to eigenvalues  ±1/2 ? of Jz and the excited state is quadruply degenerate corresponding to eigenvalues +3/2, 1/2, ? 1/2, ? 3/2 of ? Jz . 1Electronic excited state Electronic transition j=3/2 ESR Electronic ground state j=1/2 ESR Zeeman effect If one now applies a magnetic ? eld B along the z-axis, each of the angular momentum states acquires a di? erent energy. The g round state energy level thus splits into two sublevels and the excited state level into four sublevels. This is called Zeeman splitting. Now instead of a single transition of frequency ? 12 = (E2 ? E1 )/? , many transitions of frequencies close to ? 12 h are possible. Experimentally this is seen as a splitting a single absorption or emission line into several closely spaced lines.This is called Zeeman e? ect. As one would have noticed, transition should also be possible between the sublevels of the same energy level. It is indeed possible and this phenomenon is known as electron spin resonance (ESR). Electron Spin Resonance Let us try to understand the phenomenon of ESR in somewhat more detail. As ESR invloves transitions only between the sublevels of one energy level, we will not bother about the Hamiltonian of the atom/molecule which gives us the energy levels. We will only worry about the part of the Hamiltonian which is the result of the applied magnetic ? ld B, which gives us the sublevels. For simplicity, we will consider one electron with angular momentum j, in a magnetic ? eld B. In addition we have an electromagnetic ? eld of frequency ? in the direction perpendicular to B. The time-dependent Hamiltonian can thus be written as ? H=g eB ? ? ? Jz + V0 ei? t + V0†  e? i? t , 2mc ? where V0 represents the interaction of the electromagnetic ? eld with the electron. The electromagnetic ? eld is supposed to be very weak compared to the applied static ? eld B, and so one can use time-dependent perturbation theory to study this problem. The states ? hat we will use are the eigenstates of Jz : ? Jz |m = hm|m , ? where m will take 2j + 1 values, from ? j to +j. The energy of these levels is given by g where n eB ? Jz |n = 2mc n |n , = geB? n h 2mc = gB µB n. In time-dependent perturbation theory, we know that the time-dependent interaction can cause transition between various |m states. The transition rate per unit time, from i th level to j’th le vel is given by: 2? ? Wi>j = | j|V0 |i |2 ? ( j ? i ? h? ), ? h ? assuming that j > i . This expression says that transition from state |i to |j is possible when the frequency of radiation ? ( j ? i )/? . This is the condition for resonance, or in our case, h electron spin resonance. ? ? There is one important point about the form of V0 . It happens to be such that j|V0 |i is nonzero only when j = i  ± 1. This means that transition is possible between, say, | ? 3/2 and | ? 1/2 , but not between, say, | ? 3/2 and |1/2 . Such restrtictions, imposed by the kind of interaction and the nature of states, are called selection rules. 2 The ESR setup Description of the ESR Spectrometer A block diagram of the ESR Spectrometer is given in the ? gure above. Basic circuit The ? st stage of the ESR circuit consists of a critically adjusted radio frequency oscillator. This type of oscillator is required here, so that the slightest increase in its load decreases the amplitude of oscillation to an appreciable extent. The sample is kept inside the tank coil of the oscillator, which in turn, is placed in the 50 Hz magnetic ? eld generated by the Helmholtz coils. At resonance, i. e. when the frequency of oscillation becomes equal to frequency corresponding to the energy splitting of the sublevels, the oscillator amplitude registers a dip due to the absorption of power by the sample.This obviously, occurs periodically four times in each complete cycle of the supply voltage of the magnetic ? eld. The result is an amplitude modulated carrier which is then detected using a diode detector and ampli? ed by a chain of three low noise, high gain audio-frequency ampli? ers to suit the input requirement of any oscilloscope. Highly stabilized and almost ripple free power supply for the above circuit is obtained using an integrated circuit regulator. Phase shifter This can compensate the undermined phase di? erence which may be introduced in the ampli? cation stages of the spectrometer and oscilloscope. 0 Hz sweep unit A 50 Hz current ? ows through Helmholtz coils which provides a low frequency magnetic ? eld to the sample. As the resonance is observed at a few gauss only, no static magnetic ? eld is applied. R. F. Oscillator It is a transistorised radio frequency oscillator suitable for the determination of resonance frequency. Frequency range: 10 MHz to 18 MHz Accuracy: Better than 0. 5 % The Sample The sample used in our ESR setup is diphenyl-picryl-hydrazyl (DPPH). It is a widely used standard in ESR experiments. The structure of this organic molecule, shown in the ? gure, contains three benzene rings.Its important feature is that it contains a single unpaired electron, whose orbital angular momentum is 3 O2N N N NO2 O2N zero. So, the electron has only the spin angular momentum, and the material gives a g? factor which is close to 2. 0038. One thus has to deal with the simple situation where j = 1/2, and only two sublevels are involved. In conventional spectrosco py, absorption intensity is plotted against the frequency of radiation to get the absorption spectrum. In the present case, one should obtain a single abosorption geB peak at frequency ? = ( j ? i )/? , which is nothing but ? = 2mc . However, in this setup it is h di? ult to vary the frequency of radiation. So, what is done is that the frequency of radiation is ? xed at some ? 0 , and the normally static, magnetic ? eld is swept between the positive and negative extremes of a maximum ? eld value. This is done by supplying an alternating current to the Helmholts coils which are supposed to generate the magnetic ? eld. During the AC cycle, 2mc whenever the strength of the magnetic ? eld (+ve or -ve) becomes equal to B0 = ? 0ge , there is a resonance condition, and radiation is absorbed. Origin of four peaks In this experiment, the CRO is used in the x-y mode.The signal from the AC source, which supplies current for the magnetic ? eld, is fed to the X plates of the CRO, and the absorpt ion signal is B fed to the Y plates. The point on the extreme right on the CRO 2 4 3 1 screen represents the maximum positive value of the ? eld, and the point on the extreme left represents the maximum negative value ? B of the ? eld. The point at the center represents zero ? eld. Without Time the Y-plates, the point on the CRO screen goes from maximum negative value to zero, and the maximum positive value, and then back again to the mimimum value.As one can see from the ? gure, the ? eld strength becomes B0 four times in one single sweep cycle. 0 0 0 Now if the absorption signal is fed to the Y-plates, whenever the ? eld strength becomes B0 , the Y-axis will show a peak. So, one should see four peaks corresponding to points 1,2,3,4 in the ? gure. But one can see that on the X-axis of the CRO screen, points 2 and 3 are the same, because they correspond to the same value of the ? eld B0 , and points 1 and 4 are the same because they correspond to the ? eld ? B0 . So, the four peaks should overlap such that only two are visible.However, the absorption signal passes through some electronic circuitry before being fed to the Y-plates of the CRO, so it very di? cult to make sure that no phase change occurs in the process. If there is a small phase di? erence between the AC signal on the X plates and the signal on the Y plates, when points 3 and 4 are traced, the peaks do not overlap with those at 1 and 2. So, in practice one would see four peaks. If one has a way of changing the phase of, say, the Y signal, one can adjust the phase manually so that the four peaks merge into two. Getting the numbersWe have the control over the current that is passing through the Helmholtz coils, and this can also be measured. But what we actually need for our calculation is, the magnetic ? eld B applied to the sample. Let us ? rst calculate the magnetic ? eld through the Helmholtz coils. This can be done easily 4 using the Biot-Savart law. B =  µ0 4 5 3/2 I N , r where:  µ0 = 4? ? 10? 1 (cgs units) N = number of turns in each coil. r = the radius of the Helmholtz coils in cm (which is equal to their separation when they are properly arranged). I = current passing through the coils.The value of B is obtained in gauss. As the current is measured by an AC ammeter, the value of the current, and thus the ? eld, is the r. m. s. value. The peak value of the ? eld will be given by v v 8 2 I N . Bmax = 2B =  µ0 v 125 r Suppose the peak value of the ? eld (= Bmax ) corresponds to P divisions from the center on the x-axis of the CRO screen. Then if Q be the distance of the observed resonances from the center (in the units of divisions), the ? eld corresponding to the resonance will be given by: B0 = Q But the resonance condition is given by: B0 = h ? 0 ? , g µB Bmax P hich can be used to determine the value of g, once B0 is known. Now, for a ? xed ? 0 , B0 is ? xed, although one can vary the current I and get various position of the absorption peaks. Let us write the expression for B0 and see what is most accurate way to calculate it: v N  µ0 8 2 v B0 = I  · Q. rP 125 The ESR spectrometer is such that P does not vary as one varies I. So, the best way to evaluate the above expression will be to plot a graph between 1/I and Q, and ? nd out the slope, which will give the average value of I  · Q. The ? eld at the absorption peaks can be calulated as: v N  µ0 8 2 v B0 = ? lope of graph between 1/I and Q. rP 125 Procedure Connections Connections are done as follows: †¢ ESR spectrometer and power supply are connected with connecting cables. †¢ Connect the coaxial cable of the induction coil to the oscillator through the socket marked â€Å"input†. 5 †¢ Connect the Helmoltz coils to the power supply terminal marked â€Å"H† coil. †¢ Connect the â€Å"Out-put† terminal marked X, Y, E on the ESR spectrometer to the X plate, Y plate input and ground of the oscilloscope respectively and switch on the osc illoscope. †¢ Connect the power supply with AC mains.Adjustments Adjust the current in the Helmholtz coils at 150 mA. The front panel controls of the ESR spectrometer are adjusted as follows: frequency, detector and phase, all centered. Experimental procedure The X plate of the CRO is callibrated in terms of magentic ? eld as follows: 1. X ampli? er of the CRO is adjusted to obtain the maximum X de? ection (e. g. P divisions. 2. Note the current ? owing in the Helmholtz coils. The magnetic ? eld can then be calculated from the formula for B given before. Number of turn in the coils N = 500 and the radius r = 7. 7cm.The positions of the two peaks of the ESR signal at resonance is measured. Let this be Q divisions from the center. The best possible resonance peaks are obtained by varying the frequency in the range of 12 to 14 MHz and the Y sensitivity of the oscilloscope. The pahse knob is adjusted to coincide one pair of peaks with the other. The current through the coils is the n varied, keeping the frequency ? xed, and the corresponding position of the peaks from the center noted. A graph between 1/I and Q is then plotted and can be used in calculating the g-factor, as described earlier.Repeat the above procedure for di? erent values of frequency.

The direction of the Helmholtz coils should be preferable adjusted so that the ? eld is perpendicular to earth’s magnetic ? eld, which is about 0. 3 Gauss. 2. Setup the experiment at a place free from electric and magnetic ? elds and mechanical disturbances. 3. Y-output from the ESR spectrometer should be through a good shielded cable. 7
