washcloth bulk EssayUse the following as a guide. The test covers chapters 1-3 plus any supplementary articles or documentaries that were required. This is totally a guide. Remember that since this is an open book test, ANY question pertaining to the hireings could show up. Be sure to charter read thoroughly before beginning the test. Please note that starred items could be included as possible short essays (requiring a 1-2 paragraph response). I likewise suggest that you go over the discussions as well. Questions pertaining to ideas in the discussions may be included. Chapter 1Minority assort a rate gathering whose members save significantly less control or power over their own lives than do the members of a dominant or majority company. The basketb altogether team characteristics of a minority or subordinate group be un refer treatment, distinguishing fleshly or cultural traits, involuntary membership, awareness of subordination, and in-group marriage. *Racial and social groups wherefore the distinction? A racial group is a group that is companionablely mark off apart because of frank physical differences. Each society defines what would be considered the obvious physical differences.We contend for certain one of the most obvious is skin food colouring. Here in our country, we basically use black and white as the color distinction. Other countries use a unalike distinction because, for congressman, in one culture, most singulars may be classified as black save they may be several(a) shades of black which is where the racial difference occurs. In the US, umteen smaller clusters of individuals are categorized as ethnic area which holds a specific ethnic group. For example, South Brunswick has a large Indian population which is to say, Indians light upon up a large ethnic group indoors the township.New Brunswick could be another example as thither is a large community of Hispanics within the town. Whereas the term racial group is principally used to discuss minorities, the term ethnic group is used to discuss a group of individuals of the same race. Also, racial groups are defined by their physical differences and ethnic groups are defined by their cultures. Using these definitions there is clearly a distinction between the two terms. Why this distinction exists is probably so that society can categorize the individuals they are discussing.What is crucial is that racial groups are inherently who a person is so although it may be hidden or changed at times establish on the individual, a persons race is who they are. In contrast, an ethnic group can be a group of racial similar people or even religiously similar. So roughtimes, an ethnic group can be chosen. *WEB DuBois The problem of the color agate line and double consciousness W. E. B. DuBois was an African American sociologist who received a doctorate degree from Harvard and is considered the first black individual to do so.From our text we learn t hat he was instrumental in the organization of the NAACP which is a prominent organization designed to patronise the black individuals of society. (Schaefer pg 8). DuBois played a large design in gap up opinions to the disparities and distinctions of the black individuals of our society. Dubois says so very eloquently, Let not color or race be a distinction of distinction between White and Black men, regardless of worth or ability, (Schaefer pg 9). When DuBois speaks of color line, he is discussing the differences of races in regards to their color and other physical characteristics.From what I can interpret, DuBois may have developed the term double consciousness when referring to how people stick out themselves through others eyes. Also, what they see is how they measure their self worth in the grand scheme of society. * Does locomote Matter? (p. 10 begin) and the social twirl of race Our text answers this question by saying, No, alone because so many people have for so colossal acted as if difference in physical characteristics as well as geographic origin and shared culture do matter, distinct groups have been created in peoples minds. (Schaefer pg 10).Social body structure is a sociological term used to describe what opinions society places on particular athletic fields. In this case, the social construction of race refers to not what a persons race is but how society perceives the races. Race is a social construction, and this process benefits the oppressor, who defines who is privileged and who is not, (Schaefer pg 12). Basically, we all know there are numerous races that make up our culture but what determines which is the dominate race? It is argued that people in power make those determinations so they are telling everyone which race is superior to the other.Because of these opinions and social construction, yes, race is important. Race could be the difference between success and failure. Our society has not evolved enough to treat all r aces equally even though our forefathers determined that we all are equal. *Although we learn in grade school to salute the merits of living in the great resolve pot, true cultural pluralism has al personal manners been more of an ideal than a realityIn the U. S. and globally. Explain why by identifying and giving examples of the following mannikins of intergroup contact genocide, expulsion, secession, segregation, amalgamation, assimilation, and pluralism.Pluralism implies that discordant groups in a society have mutual respect for one anothers culture, a respect that allow fors minorities to express their own culture without pathetic disfavor or discrimination, (Schaefer pg 25). Our text describes this term as an ideal meaning that it is something our society hopes to be able to practice amongst all individuals. However, it is quick to note that it should be more like a reality in the sense that it is something that society is obligated to believe in, (Schaefer pg 26).It can definitely be seen as a conflict within society as individuals may be forced to make opinions based on what is right versus what they may have been taught to believe all their lives. The US is truly a melting pot meaning a society with a variety of cultures and races that make up the whole. Because of this, we have an obligation to respect every different culture as well as every race. Social construction tends to make this a difficult goal to obtain but there are many organizations in place which try to make these gaps smaller.There are many emoluments to integrating one culture into another. For example, in my hometown, many of us love to eat sushi. With the uprising of this howling(prenominal) food choice, those that are not Asian have been able to dive into the culture through a wonderful eating experience. Another example could be many of the courses offered here at Rutgers. There are courses in Russian literature and Chinese film for example. I would imagine that a large p ortion of the participants may have some cultural interest but there are many that take these types of classes undecomposed to broaden their own experiences.These types of classes could help in making the gap smaller between cultures and could help to improve cultural pluralism. Chapter 2 Ethnocentrism or the tendency to presume that ones culture and way of conduct are superior to all others. This is a form of in only whenice and would result in discrimination. Our text describes this (pg34) as a motivating factor behind some criminal acts. *Prejudice and favouritism Prejudice is a negative attitude toward an entire category of people. For example, the Klu Klux Klan who we were unresolved to in the CP Ellis story was extremely prejudice against blacks.Another example would be Nazi germany and Hitlers prejudice again jewish people. Showing both of these examples also give us a look at some of the most horrendous hate crimes in human history. Discrimination is the denial of opp ortunities and equal rights to individuals and groups because of prejudice or for other ar insect biterary debates. Whereas prejudice is an attitude, discrimination is an action. For example, if someone says they dont like a person because they are black, that is prejudice. If that same person refuses to allow the black individual into their restaurant, that is discrimination.Our society has had some severe cases of both of these and we are still struggling to overcome some of the cruelties of the past. Unfortunately, these actions didnt die off in the past, I think they have just become less obvious. Merton and LaPiere Studies Robert Merton showed that prejudice and discrimination are related to each other but are not the same. He gives 4 types of people when discussing this issue and they are, un discriminative nondiscriminatory (all weather liberal), unprejudiced discriminator (reluctant liberal), prejudiced nondiscriminatory (timid bigot), and prejudiced discriminator (all wea ther bigot), (Schaefer pg 36).I can forthwith tell from the descriptions that the final one would be the most severe because the implications to the term show that this individual is always in a mode that is highly discriminatory. I would agree with these categories mostly based on personal observations and knowing some people that do have tendencies to be discriminatory. Mertons is saying that not all individuals personal opinions and attitudes toward other should be construed as negative behavior as well. The LaPiere study was around half a century ago and exposed the kindred between racial attitudes and social conduct, (Schaefer pg 37).What LaPiere did was travel with a Chinese couple and observes if the racial attitudes he expected or were historically evident actually occurred. His close was that it wasnt apparent all the time. This could show that people tend to be polite in person but what they say or do in private is another situation. *Theories of prejudice Scapegoating theory, Authoritarian Personality, Exploitation theory, Normative mount Scapegoating says that prejudiced people believe they are societys victims. They blame what wondering(a) things happen to them or other misfortunes on people of a different race.Again, the CP Ellis story we read later our lessons was a perfect example. CP Ellis felt he was stipulation a very hard life and has suffered not only with personal troubles but also money issues. He wanted to blame someone and his draw with his father and the Klan made it easy for him to blame the blacks. Authoritarian Personality is a psychological construct of a personality type likely to be prejudiced and to use others as scapegoats, (Schaefer pg 39). So, using the same previous example, it could be said the CP Ellis suffers from authoritarian personality because his actions of using the blacks as scapegoats.Exploitation theory is, a bolshy theory that views racial subordination in the US as a manifestation of the class system inherent in capitalism, (Schaefer pg 39). It is to say that in the hobo camp there is a food chain, the lion eats the rabbit that eats the mice, etc. Within current society, it is expected that there are different classes of individuals and some who will say this is a necessary part of life. It is unfortunate that sometimes this class system reflects on a specific racial group. The normative approach is, the view that prejudice is influenced by societal norms and situations that encourage or discourage the tolerance of minorities, (Schaefer pg 40).This is a very important concept because it shows that a lot of the actions and opinions of people that are discriminatory get that way because they are taught that or they grow up in an atmosphere of prejudice. Again, CP Ellis grew up with a Klan father so it was only innate that he developed some of these tendencies as well. What is even more significant is being able to recognize all these theories and to combat their existence with e ducation. more or less individuals may be beyond help but many can learn to change given the right education.Stereotypes and Racial Profiling Stereotypes are punic generalizations slightly all members of a group that do not take individual differences into account. For example, Hitler did not care how much or little Jewish hereditary pattern an individual had when he systematically exterminated millions, he only cared that a drop of Jewish blood ran through their veins. He didnt care about the persons contributions to society or their intelligence. Part of this concept of stereotyping is a term called racial profiling which is any arbitrary police initiated action based on race, ethnicity, or natural origin rather than a persons belief.We see many newsworthiness reports about this very subject where police use uncalled-for force or violence just because of a persons race. A post racial era? Color-blind racial discrimination Color-blind racism refers to the use of race-neutr al principles to defend the racially unequal status quo. One example the book gives is how Asians are rarely used in feature films except where martial arts is also highlighted. Postracialism is a common theme and is another tem used to describe color-blind racism. Other terms are individualism and aversive racism.*Reducing prejudice (p. 48 begin) The question remains later on all these discussions, can prejudice be reduced? Our text suggests many different ways in which it is possible to treat and educate those who practice prejudicial attitudes. For example, education, mass media, avoidance versus friendship, and corporate response (diversity training).The education portion of reducing prejudice would be in the form of programs and conferences designed at teaching people what to look for, ways to combat the situations and additional training that could be passed on.For example, we viewed the video about Jane Eliotts school. Her program with small children appears to be groundbr eaking and based on the follow up with the students years later, also successful. Another important tool is mass media. For example, in my previous women study classes I was exposed to the way the media shows women. There are a excessive amount of commercials featuring women as the cook, cleaner, and childcare provider however very limited showing a man in the same roles.There have been advances however and our text discusses one such TV show called The Cosbys which had a huge television audience which included all races, not just black as all the characters on the show were, (Schaefer pg 49). The next area is avoidance versus friendship. This discusses the social distance scale by Robert Park and Ernest Burgess which asks people how willing they would be to interact with various racial and ethnic groups in specified social situations, (Schaefer pg 51). The importance of this study is to show the patterns that become evident particularly within the White American and Europeans.Thi s is an example of the Social Distance Scale. There was another scale mentioned called the Equal Status Contact which states, intergroup contact between people of equal status in sympathetic circumstances will cause them to become less prejudiced and to abandon previously held stereotypes, (Schaefer pgs 51-52). Therefore, by incorporating more fun and interesting activities that are not racially motivated, the pattern of prejudice could be learned to be reduced. What do you think about Jane Eliotts efforts at reducing prejudice (presented in the documentary A Class Divided)?What are the strengths and weaknesses of her methods? What else might you suggest? Jane Elliotts efforts in the documentary we watched for class should be applauded. It was interesting to note that the town where Jane worked as a instructor was primarily white Christian and to this day, that status hasnt changed much. However, Jane continues to give her lesson on prejudice and it appears to be particularly help ful. When the students of one class were interviewed years later subsequently watching themselves in the documentary, it was fascinating to see how emotional they were.Even years later, the lesson was felt very deeply. The strengths would be the instant feelings of rejection on the children. But the weakness could be that they may recognize it is not a real situation. Also, if the lessons taught are not encouraged at home or within their community, it may not make a difference. Although starting young is particularly important, I would propose all family members be exposed to the lesson. The documentary mentioned how the concepts used were taken into the work force within a conference type atmosphere.Although adults do react the same, I personally do not see the impact as much as I did with the small children. That may be because as we get older, we get tougher in our emotions and it could be hard to break old habits. Chapter 3 *Total discrimination Discrimination is the denial of opportunities and equal rights to individuals and groups because of prejudice or for other arbitrary reasons, (Schaefer pg 61). I think in the US we recognize that there is discrimination but many choose to believe that they are incapable of it or that it is not as horrible as people may make it out to be.Total discrimination is a more recent concept which is, current discrimination operating in the labor market and past discrimination, (Schaefer pg 62). It is saying that because of particular items in a persons past like education and social status, individuals are discriminated against in the work place. That discrimination can show itself in such areas as hiring, advancement and even pay scales. It is not something that is randomly made up but an actual occurrence. For example, someone who was not provided a decent education because of their social status or ethnic group would have difficulty finding advanced conflict.In current day, employers wont even look at a person unless they have a full four year degree or higher. Many individuals just arent able to take advantage of that type of education. Hate Crimes when a victim is selected because of certain characteristics such as race, ethnicity, religion or sexual orientation. We see numerous hate crimes in the news almost daily. The Rutgers campus recently became a focal point of a perceived hate crime when Tyler Clementi, a student at Rutgers, committed suicide after his roommates posted him in gay videos.*Institutional discrimination (Why is institutional discrimination considered more important than the everyday discrimination of individuals? ) This form of discrimination is the denial of opportunities and equal rights to individuals and groups that result from the normal operations of society, (Schaefer pg 65). This is particularly important because it goes to the root of functioning as an average human being within society. One example mentioned is that IQ tests are geared towards middle class white American children therefore any other child taking the test would be at a disadvantage before even answering the questions.If everyone starts out on an even playing field and thence points are taken away for items that cannot be mastered, then society may be working towards treating every individual equally. But this isnt the case. When a hard working Hispanic man who has been in his employment for 20 years is denied credit or needs additional collateral when compared to a hard working white man, this type of discrimination is inexcusable because it comes from a persons perception not from what abilities they may or may not have.Measuring discrimination (p.66 begin) There are many ways in which society measures discrimination. For example, economics is probably the most prevalent as it is the easiest to examine and study. The chart in our text shows that median incomes vary quite a bit depending on a persons race, ethnicity and even gender. What is particularly interesting to me, but not surprising, is that white American males do not hold the highest prenomen any longer. This now goes to the group of Asian American men within society. Although the salaries are higher, the statistics havent changed much.Hispanics and Native Americans still fall on the worst end of the economic tier. *Civil Rights Act of 1964 Prohibited discrimination in public accommodations such as hotels, motels, restaurants, gas stations and amusement parks. Publicly have facilities such as parks, stadiums and swimming pools also prohibited from discriminating. Also forbade discrimination in all federally supported programs and institutions such as hospitals, colleges and road construction projects. Since then there have been numerous amendments because as times change, so does the need for the Act to change. (pg 69)Redlining African Americans, Latinos, and other fall victim to redlining or the pattern of discrimination against people trying to buy homes in minority and racially chan ging neighborhoods. *Why does the text author make the distinction between income and wealthiness? Income refers to salaries and wages, and wealth is a more inclusive term that encompasses all of a persons material assets including democracy, stocks and other types of property, (Schaefer pg 71). I feel the main reason for the distinction is because many individuals of specific ethnic groups cannot obtain property, sometimes even regardless of the income they make.Because of this, for some individuals, wealth may not be a possibility. *environmental justice Refers to the efforts to ensure that hazardous substances are controlled so that all communities receive protection regardless of race or socioeconomic circumstance. (Schaefer pg 72-73). assentient action Affirmative action is the positive effort to recruit subordinate-group members, including women, for jobs, promotions, and educational opportunities. (Schaefer pg 73). It was a phrased coined by President John F.Kennedy call ing all to the cause of making sure that applicants were do by properly and fairly during all stages of the interview through employment process. Reverse discrimination is an emotional term because it conjures up the notion that somehow women and minorities will subject white men in the US to the same treatment received by minorities during the last three centuries. (Schaefer pg 76) Glass Ceiling Refers to the barrier that blocks the promotion of a qualified worker because of gender or minority membership. (Schaefer pg 78). *Be able to discuss the article on CP Ellis..What led to his involvement in the Klan and what led to his sworn statement of it? What factors led to the change? What made CP Ellis join the Klan? What made him change? Why is this relevant today? Does CPs account support any of the theories we have read about in this section (for example, scapegoat theory on page 38 of our textbook or the contact hypothesis on page 51)? What role does the economy play in shaping intergroup relations? (You can speculate on this last one) The story of CP Ellis was particularly interesting because of the evolution his life took.I think there were many reasons that guided CP Ellis into the paths he choose in life. For example, he had a rough upbringing and then when he was matrimonial and had his own children, he suffered a lot as well. It appears his life was a constant struggle to survive while he worked extremely hard to support his family. The moment that the Klan came into his life was when he was at his service station observing Klan members. They would come in talking once a week and they approached him to join the group with them.He was immediately interested because he felt his current struggles needed to be blamed on someone and who better, in his opinion, then the black people. This came natural to him because he was familiar with the Klan from his father. I feel that his attitudes began to change when he started to notice that the government was d iscriminating against all people, not just blacks. He started to understand what those in power were doing to every citizen and it was a real eye opener. One of the theories we discussed during this section is called scapegoat theory.Scapegoating theory says that prejudiced people believe they are societys victims, (Schaefer pg 38). I can definitely see the correlation between this theory and CP Ellis feelings towards black people. He needed to blame someone for his troubles and the hard times he was experiencing so he selected the group of individuals that he had grown up feeling negatively against. The root meaning of scapegoating is that it is more convenient to blame another individual then to take responsibility for a persons own short comings.Intergroup relations are how we look at ourselves and how we look at others and the way that different groups interact with each other within society. I feel that the economy plays a huge role in intergroup relations because some races an d ethnic groups are not only defined by the color of their skin but also by their social class. Intergroup relations focus on the comparisons of groups based on many aspects including economic ones. Even as an outsider speculating on this subject, it is easy to see that under many circumstances, black individuals are stereotypically placed in a different economic level than many white individuals are.It is some of these types of opinions that historically have caused animosity amongst difference ethnic groups. Unit 9 calendar week 3 Some notes on the Social Construction of Race Notes on The One-Drop-Rule and the Social Construction of Race 2/4/2013 Eleanor LaPointe (Note that many of the ideas below were presented by you in Discussion B last week. This is a synopsis with perhaps a few additional ideas. ) The idea of race does not come from biology. It started in Europe as Europeans moved out across the world and found that they needed a way to control people as they took over thei r land or enslaved or exterminated them.The invention of scientific racism was one of the most effective weapons devised to conquer and subjugate. Carolus Linnaeus was a botanist in the 1700s (from Norway, I believe). He is credited with the first scientific classification of humans into groups now called races. He wanted to classify humans in the same way that clams, flowers, and insects were classified. But, he wasnt just an objective nonpartisan scientist. He classified in a particular wayone that put his group on top and all others below. The result was the beginnings of a scientifically-backed gradable ordering of people.It should be mentioned that even during Linnaeuss time, the ideas he put forth were highly contested. That is, not everyone agreed. In fact many disagreed, including scientists like the German physiologist Blumenbach who felt that no real differences existed between people and that any visible differences were superficial. However, Linnaeuss ideas were more s uccessfully incorporated into popular ideologies (or mythologies) because they supported the dominate group need to justify exploitation inequalities at the time. That is, the idea of race allowed oppressors to define who was privileged and who was not.Since this time, how humans have been categorized has changed a lot and there is much variation from place to place. How a Race is defined at any given time depends on an arbitrary set of features chosen to suit the labelers purposes or biases or both. A high-priced example is how U. S. laws concerning the definition of race have been used. Early on in the U. S. the question became How to define or draw the line? This is an ongoing question. But in any case, from state to state, there was very little consistency in terms of how race would be defined. Some segregation-era artifacts includeMissouri 1/8 or more Negro blood was the criterion. Georgia The term white person shall include only persons of the white race, who have no ascerta inable quality of either Negro, African, Western Indian, Asiatic Indian, Mongolian, Japanese or Chinese blood in their veins. Virginia Had a similar law but with exceptions. A person could have a little Indian or African blood. Arent these old laws though Actually, some are still on the books and have been upheld as recently as 1982. Louisiana is a good example. In this state, the 1/32 law was actually created in 1971 (prior to this, a persons race classification was less formal).On kinfolk of 1982, Susie Phipps obtained her birth certificate and was surprised to find that it listed her as black. At the age of 49, she had always thought she was white She brought the matter to court and requested it be changed, but the state/court objected after being shown an 11-generation family tree with ancestors who included an early eighteenth-century black slave and a white plantation owner. The court claimed that she was 3/32 blackenough to make her black under state law. What is interesti ng is that the state of Louisiana could have decided that this law was outdated law and of no use anymore, but it did notThe bottom line is that historically, as now, where black and white begins and ends depends on who is doing the defining and for what purpose. Moreover, if you are raised in the U. S. , it is nearly impossible to escape the localisation of function that race has on how we think about ourselves and others. No matter how it is used these days, it is important to keep in mind the origins of these ideas and institutionalized practices as a set of justifications in a hierarchical system allowing the privileged to reduce competition for valued resources. For ideas on the social construction of race in other countries, see chapter 16 in our text.

Role Of Education in Sustainable Development Essay Example for Free

Role Of Education in sustainable Development EssaySustainable development is that development which each(prenominal)ow for meet the present needs of the community without compromising the ability of future generations to meet their own needs. Environmental knowledge involves among separate things the pro ken of information, recognizing values, clarifying concepts etc in order to develop skills and attitudes that enable the community to understand and appreciate the relationship between their cultures and their physical surroundings.At international fora, attempts entertain been made to promote environmental reading. In the year 1975 in Belgrade, the program for international environmental education was started followed by the conference in Tsibilisi in 1977, Nevada 1979, capital of the Russian Federation 1987, . . Since then the council of European countries has twice called on member countries to advance on environmental education in all sectors of education.There is use upd a plethoric policy to ensure that the findings of research on environmental science are flop applied to ensure that the world is safe for further development with no further destruction of the natural resources.It is therefore necessary to involve the players in political, economic and cultural sectors in designing environmental programs. By doing this, we result line up that all these players deal turned environmentalists and we stick out expect a conflict of interest of style in the approach of environmental matters. This is because sustainable development is a contested territory with its ownership disputed by forces with very diverse interests.Its thus difficult to foresee any slackening of the effort on those who will continue to impose development to suit their ends invoking modernity, national integration, economic growth and other slogans (Adams 1990, p199). With challenges as these, education is a must in order to buzz off these interests groups together and com e up with backbreaking policy on sustainabledevelopment, infact one that is conscious of future needs.OBSTACLES TO SUSTAINABLE DEVELOPMENTThere are mixed obstacles to sustainable development which include-1. Lack of awareness on issues involved,2. Political unacceptability of obvious steps forward,3. Opposition by groups with vested interests,4. Inadequacy of institutional tool for integrating environment and development.SOLUTIONSTo overcome these obstacles, there is a feeling among many groups that there is a need to replace the ideas and values that underlie the complex and distinct obstacles with a new approach and reshaping of ideas and values. To do this we need not just a modification, but a total revolution of our thinking. This can well be achieved through a well-designed education approach.ROLE OF EDUCATIONEducation plays a major role in enhancing peoples awareness well-nigh bio-diversity preservation as well as sustainable development. It leads to actualization of conse rvation cognition and skills which in turn help in broadening peoples knowledge about conservation, thus making them functional members of the society.Education will enlighten stakeholders on various issues relating to sustainable development and bio-diversity conservation. Also education will sensify them to participate fully in campaigns against any act or development that threaten future sustainability.Consequently, education em billets stakeholders to take increasing charge of their own developments as key ingredients combined with a clear knowledge of environmental constraints and of requirements to meet basic needs. This enables people to understand their need for and importance of biodiversity for now and in the future. It is this education which will enable us realisethat sustainable development confronts not just society, but each of us at the heart of his or her purpose. It invites us to give practical support to the values of social equity, human worth and ecological hea lth. Education questions our readiness to involve ourselves in the struggle for turn, it challenges our willingness to contribute in greater measure to the activities of NGOs and dedicated individuals who campaign on our behalf. Moreover, education asks us to accept that the small beginnings from which so many successful campaigns shed started resides within ourselves.As Laszlo (1989) puts it, we contemplate changing almost anything on this earth except ourselves, and this is due to the inner constraints in our visions and values that can only be removed through education. This is because education will explain the need for and importance of attitude and behaviour commute in our pursuit for development, as a solvent we will realise that we owe the future generations what we have today.It is education that will enable us reach a conclusion as Max-reef (1991,P113) explains -I have reached the conclusion that I lack the power to change the world or any significant part of it, I onl y have the power to change myself. And the fascinating thing is that if I decide to change myself, there is no police force in the world that can prevent me doing so. It is my decision and if I want to do it, I can do it. Now the point is that if I change myself, something whitethorn happen as a consequence that may lead to a change in the world. As such awareness plows more general, sustainable development will be regarded seriously by the people who really count not just elites but people generally.Education whether formal or informal has been proved to be a mesomorphic tool in promoting changes in the attitudes and perceptions of people about a resource. A series of conferences under the auspices of UNDP have been held to address issues pertaining to the link between sound natural resource management and sustainable development, environmental conservation and improved human welfare.Education for sustainable development will not only wee-wee awareness of theglobal crisis but mu st place it at the heart of the curriculum. It must be ecological sort of than environmental encouraging broad holistic thinking, reading the need for structural change and promoting the correct industriousness of reductionist thinking to specific technical problems. It will embrace all the means of the change discussed in this paper and alert stakeholders to the feasibility of alternative practices. Further, education will not only inform stakeholders, but also allow them to participate in decision making process about biodiversity conservation and thus promoting change.Through education, stakeholders will not only become acquinted with one anothers vision about healthy ecosystems but also stimulates them to formulate their own visions relating to biodiversity. It will not only teach them about holism but will require them to think holistically. Holistic thinking is a particularly important means of change for sustainable development because it attempts to figure out the consequ ences. Holistic approach tries to holler the problem simple solutions, create and to identify more satisfactory structural solutions. Holistic thinking led one farmer in Kenya, sickened at having to mop up the elephants ruining his crops, to adopt an alternative form of land use, accommodating not only his own interest but also those of elephants, of tourists who wanted to see elephants and of topical anesthetic people who could supplement their subsistence economy with income from tourism.Education will also help us to see the need of putting people root in all our endeavours in sustainable development and biodiversity conservation. Putting people first means quite simply valuing people for themselves, for what they are rather than for what they can do, or how they can perform in the service of some interest whose ends may be quite radically opposed to the meeting of human need. Putting people first also means empowerment- a process by which those who are or feel excluded from decision making are enabled to participate in it. It involves the transfer of power from those in authority to smaller groups.In some countries this has to begin with establishing or re-establishing political rights and other basic freedoms. (A recent example is the return to free elections in Malawi and Kenya). Onlythen can a start be made to provide education and training to raise awareness and allow stakeholders to play an stiff role in political process. Empowerment also refers to what Paul Freire, the Brazilian educationist calls Conscientization or education for consciousness, by which communities and individuals become aware of the reasons for their poverty and oppression and begin to discuss what they themselves can do about it without enabling action by the authorities.Ecological education will not only teach about empowerment but will enable stakeholders to fulfil their aspiration by helping them to develop their full range of abilities. By paying equal charge to emotio nal and intellectual development, education will teach the basic life skills people need to establish identities and grow as individuals. By encouraging creativity, inscription and initiative, it will equip stakeholders to take responsibility for themselves and their future, and to avoid dependency on biodiversity without ensuring its sustainability through sound management practices. It will also focus on relationships and teach what Harrison (1990,p203) calls the work of human communication of caring and nurturance, of tending the personal bonds of the community. It is envisaged that well organised education will also enhance our ability to denote with each other, not just on the level of day to day communication skill, but more importantly by acknowledging others identities and rights to a resource.This education will initiate a process of lifelong growth in awareness and aspiration. An individuals readiness to participate in that process, at however lowly or profound a level, will be more important than acquiring impressive qualifications, for as Paul Freire (1972) points out, we are all unfinished human beings with a allegiance to improve unfinished reality.Without the opportunity to develop their potential, individuals can not develop fully in discussions and initiatives on which progress to more sustainable development depends. Therefore, properly resourced and directed education will ensure that all stakeholders become the beneficiaries of the care, concern and skills of others.CONCLUSIONIn a world where the challenge of sustainable development is an imperative, rather than an option, we can not afford to debar people from participating by making them feel failures, whether academic failures as a result of the rigid application of elitist standards, or social or personal failures as a result of inadequate evolutions of both their needs and their potential. Therefore, I envisage that properly resourced and directed education aimed at encouraging the development of sensitivity, awareness, critical thinking, problem solving and active participation in biodiversity conservation campaigns, will enable stakeholders not only to become aware of the issues and be able to act on that awareness, but will be equipped with the skills required to contribute effectively to the debate. They will learn to plan, organise, slip away with others, develop strategies and create alliances with an aim of promoting sustainable development and ensuring biodiversity conservation.

confounding factor or lurking variable

throw factor or lurking uncertainConfounding versatile, also known as confounding factor or lurking variable kitty be defined as an undesirable variable that has an influence on the relationship between the variables of an experiment. Although they argon non the variable of installive interest (i.e. the independent variable), they can influence the outcome of an experiment and they be considered to be undesirable as they could add computer error to an experiment. A proper intentional experiment should aim to decrease or control the influence of much(prenominal) confounding variables in order to avoid type 1 error an error that raises a false positive conclusion that the independent variables cede a casual relationship with the dependent variable. The relationship between the two observed variables is called a spurious relationship, hence a confounding variable is a threat to the validity of inferences made about cause and effect, i.e. the internal validity because the ob served effect should be attrisolelyed to the independent variable rather than to the confounding variable.An physical exercise can be illustrated by the relationship between ice cream sales and drowning deaths. When these variables are entered into a statistical analysis, they whitethorn show a positive and potentially statistically significant correlation. However, it is a mistake to infer a causal relationship (i.e., ice cream causes drowning) because an important confounding variable which causes both ice cream sales and an increase in drowning deaths has non been accounted for i.e. summertime. Although there is a clay of literature of criteria for causality, Pearl claimed that confounding variables cannot be defined in terms of statistical notions alone some causal assumptions are sometimes necessary. For example, when causal assumptions are being defined in the form of causal graphs, a simple criterion called backdoor leave behind identify sets of confounding variables.Type s of confounding variablesConfounding variables whitethorn also be categorized according to their source the choice of measurement instrument, situational characteristics, or inter-individual differences.SolutionThere are several ways to combat confounding variables in an observational design by excluding or controlling it. Here is the followingCase control studies by assigning the same confounding variables to both the experimental and control group can control for such confounder, for example, if the cause of multiple infarct insanity is being studied, age and sex could be the confounding variables, hence these factors should be matched paired between the two participant groups. In addition, randomization is also another solution as having all confounding variables (whether known or unknown) pass on be equally distributed across all groups.Cohort studies this is done by admitting a special(prenominal) group of participants into the sampling population, for example a specific age range that whitethorn affect multiple infarct dementia, therefore only a certain group is chosen for the study design such as male aged 45-50 years old. This would limit the degree of matching between the groups and also cohorts can be comparable in regard to the realistic confounding variable.Stratification in the example of multiple infarct dementia study, physical activity is hypothesized to be a variable that can prevent this dementia from happening. With age as a possible confounder. The sampling data will then be stratified by age group so that the stand between physical activity and dementia can be analyzed per age group. If different age group yields different risk of exposure ratios (this can be analyzed by statistical as well asls called Mantel-Haenszel method actings), then age is seen as a confounding variable.Despite solutions for the controlling and limiting confounding variables, these strategies have limitations too. For example if a participant in the case-c ontrol study is a 47year old African-American from Alaska, avid tennis player, vegetarian, workings as an engineer and suffer from multiple infarct dementia. prim matching would require a person of the same characteristics but with the sole difference of being healthy. This is extremely difficult to achieve and there is a risk of over- or undermatching of the study population. Additionally, in a cohort study, too m each plenty may be excluded with this criteria, and in stratification, case-by-case strata can get too narrow and contain only a small, non-significant number of samples.RandomizationOne of the most common reasons for the existence of confounding variable is when the experimental design does not randomly assign participants to groups or some types of individual difference such as ability, extroversion, height and weight. For example, studies involving a comparison between men and women are inherently plagued with confounding variables since the social environment for males and females is very different to start with. However, this does not mean that there is no value in gender comparison studies or other studies that does not employ random assignment but it implies that results interpretation should be done cautiously. In sum, random assignment is a useful and almighty tool in experimental design. Although it does not minimize the overall amount of extraneous variable in an experiment, it aims to equalize the error that may occur as a result of extraneous variable, therefore it can greatly decrease systematic error error that varies within the independent variable.Multivariate analysesAnother method for controlling confounding variable is by the use of covariates in multivariate analyses. However, this only gives little information about the strength of the confounding variable compared to stratification methods. Further much(prenominal), confounding variables are not always known or measurable which means residual confounding (term for incom pletely controlled confounding) may appear. In an experimental design, covariate tolerance can help to reduce the noise in an outcome divergence whilst enabling the manipulation effect to be performed. In sum, successful randomization can minimize confounding variables by bother measured and unmeasured factors, whereas statistical control addresses only confounding variables that have been measured and can introduce more confounding variables and other biases through inappropriate control.Mismeasurement and mis-specificationAlthough it is important to spot confounding variables in a study there is often a risk of having a statistically controlled but imperfectly measured factor that may confound an association of the variables. This is termed residual confounding which describes the mismeasurement and an example is given to illustrate this. In a study example, it was found that people with high rate of vacation is correlated with lower risk of mortality. Several explanations can account for this as vacation mitigates stress, diminishes vexation and encourage more exercise. On the other hand, healthier people might be more likely to travel so vacation may not be a genuine causal factor but only a marker of initial health status that naturally predicts longevity. Consequently, vacation may remain to be a significant predictor even after adjusting for baseline health status as the covariate. It is therefore easy to construct a series of potential confounders but many would lack plausibility. For example, people with more friends may have more vacations and friend was indeed the predictor variable instead, low-stress working environment and wide range of food (I.e. completeness of diet) may all attribute to prolong life too. However, because plausibility is a highly subjective factor for considering whether large potential founders are included. To identify confounders Priori knowledge of the likely causal pathways are required. The major drawback of this is that observational studies imply that the strength of any causal inference will depend on the biologic plausibility of the putative factor, and the implausibility of uncontrolled potential confounders. In addition, observations contain some judgmental component which varies from experimenters. For example, vacation may prolong longevity because sick people tend to travel less, to deal with this. Measurements of participants initial health may be used as an change but this however cannot be assessed without error. Moreover, health can be measured in so many different ways and not all can be included and controlled for. This raises more and more questions such as can the use of initial stress test be used to capture aspects of health wooly by vacation? Is body mass index relevant? Consequently, even if the optimal measure of confounder is used it is measured with error and adjustment for it may not eliminate the effects of vacations.From the statistical analysis perspective, poorly measured confounding variables causes more problems as its effect may not be linear, by expect linearity on the outcome as specified by the modelling by entering confounding variables as a covariate in standard fixing models may not fully adjust for the confounder effects are not linear on that scale.Mediators and confoundersThere is a common conflict that different causal explanations can be possible when adjustment is used to reduce or eliminate the predictive power of the independent variable. For example, a confounding variable may sometimes be a marker of some causal factors but it is not directly involved in the causal chain from one variable to another and there is a problem of over-adjustment. Considering an example on the hypothesis that high blood pressure (BP) reaction to stress causes Hypertension. To test this hypothesis, a longitudinal study should be conducted where BP responsiveness and resting BP levels of a large group of participants should be measured. Result findings should report that excessive reactivity to be the risk factor for afterwards hypertension but the problem is reactivity may just be a marker for elevated BP resting level and it is not important per se. consistent with this problem, those participants with higher resting BP may correlate with high BP reactivity scores. To control for the current confounding variable, the initial resting BP levels should be adjusted by regression analysis which llustrates whether BP reactivity is attributed to any predictive information beside just the initial resting BP level. This may show that reactivity is no longer a very predictive factor and most of the variation in the follow-up BP levels may be accounted for by the initial resting levels. However, this does not mean that reactivity is not causally related to future BP status, i.e. if increased reactivity preceded initial increase in resting BP level, it could also be responsible in part for the initial increase in resting BP level. This is a situation whereby a single variable may have both confounding and mediating roles simultaneously. The example of vacation and mortality is used to illustrate this assuming that people who go on more vacations are less likely to die over a 5-year longitudinal study, including a factor initial health status in the regression model could eliminate this association. Alternatively, if people in poor health take fewer vacations then this elimination may reflect the removal of a confounding variable by health status. However, if the participants tendencies to go on vacation are constant over the 5 year period then health status will reflect the cumulative health impact of a lifetimes vacation habits. This shows that health status will contribute partly as a mediator of pass effects. This confusion between a mediator and a confounder will be less apparent if the risk factor is not stable over time. For example if the participant has only just started having vacations, then these will not be reflected in the initial health status and may have higher hazard to predict subsequent health with initial health status as a covariate in the analysis. However, if these changes become out of control, it can create a quasi-experimental design. For example, if people take vacations due to change in their company policy rather than the reason of making friends or have spare time, and other group have less vacation for the same reason. Then in this case, it is possible to assess the effect of vacation independently of initial health status.In sum, indiscriminate adjustment of covariates may result in erroneous conclusions and many socialdemographic variables can be mediated by other factors such as low income, unfulfilling jobs, no friends and so forth moreover, there may also be other intermediate variables like self-determinations and release of stress hormones that may affect the results. Considering the wide range of variables listed, any inexact measures of them m ay lead to a reduction or elimination of predictive power. Moreover, by controlling a mediator may produce further confounding variables, which will then increase or decrease the associations of the independent and dependent measures. Furthermore, it may even create a new spurious association when in fact no effect is present.In sum, despite the number of limitations discussed in this critical review, they have an important role in behavioural research as randomized trials are sometimes found to be impractical and unethical. In spite of the hazardous statistical control of confounding variables will gain acumen into special cautions in drawing conclusions and writing research in the future.

Literary Analysis Of Beowulf English Literature Essay

Literary Analysis Of Beowulf English Literature EssayEver sense the beginning of judgment of conviction there have been larger-than-life stories about heros and undaunted leaders who take down evil and bring peace to the people they protect, Beowulf is no different from this. Beowulf is an epic reputation that relates well to the time that it was introduced by having the stories of the epic battles and the defeats of the treacherous monsters that kept everyone entertained during this era. Not only does Beowulf represent the era well but it also has very interesting characters, themes and symbols that service of process teach us lessons that are very much so needed in todays society. Beowulf teaches us courage, it shows us characters such as Beowulf himself that are true to his intelligence operation and self-confident, and it also shows us symbols that give an see of perfection and the hope that he brings to the people that believe in his word.When Beowulf arrives to the land of the Danes, as soon as they quayage and get off of their ship Beowulf shows his courage instantly by taking the lead and explaining to the guards that watched out for raiders and enemy ships approaching who they were and where they were from so that they may advance to the Heorot which he had hear much about. subsequently they get inside Heorot Beowulf truly shows his courage when he tells Hrothgar about tout ensemble of the triumphs he had when he was younger and how when he heard of their problem with Grendel and how he planned to be a match for him so that he could be the one to bring peace back to Heorot. The news of Grendel, problematic to ignore, reached me at home sailors brought stories of the plight you suffer in this legendary hall, how it lies deserted, empty and useless once the evening light hides itself under heavens dome. Now I mean to be a match for Grendel, settle the out derive in single combat. (410 414 425-426) He also explains how he isnt afraid of st opping point because if he is handout to die it will happen whether he wants it to or not and by doing this he gives king Hrothgar peace by knowing that he is courageous nice to take on this challenge and not be afraid by the terror that his people have been facing for the last 12 years. whichever one death fells must deem it a just judgment by God Fate goes ever as fate must. (440-441 455).Not only is Beowulf extremely courageous but he is the mold that heros model themselves after he is noble, true to his word and his unquestion open trust in his skills. When Beowulf gets to Heorot and they begin to feast Unfearth goes up to Beowulf and questions the career that he and Brecca had in the fierce open sea aphorism that no matter what he had done before that he would not be able to defeat Grendel because many great warriors had come before him and his fate would be no different, however Beowulf has trust in his skills that God has graced him with just as he did when he raced Bre cca in the open sea. The truth is this when the going was heavy in those high waves, I was the strongest swimmer of all (532 534). By Beowulf saying this he is allow Unfearth know that now as well as when he raced Brecca he is the best and will not be beaten. Beowulf then begins to challenge Unfearths skills by saying if he was really as courageous as he has been saying he is then Grendel wouldnt be able to get away with killing all of Hrothgars people and that Beowulf will show Grendel different and that he will show him his skill. He knows he can trample down you Danes to his hearts content, humiliate and reach without fear of reprisal. But he will find me different. I will show him how Geats shape to kill in the heart of battle. (599 603) Beowulf by saying this is demonstrate that he has great confidence in his skill as a warrior and that he do what Unfearth has been unable to do, which is free Heorot of their burden of Grendel. Later in the story Grendel appears in the nigh t to eat the bodies of the soldiers that are in the middle of their slumber inside of Heorot and Beowulf is waiting for him to do as he said he would. After their battle Grendel had been beaten by Beowulf Grendel was driven under the fen-banks, fatally hurt (818-819) by defeating Grendel Beowulf was true to his word and accomplished what he had set out to do The Geat captain had boldly fulfilled his boast to the Danes he had healed and relieved a huge distress (827 829).Beowulf has many things inside the story that a exemplary of God and how he can deliver us from our demons, or Grendel in this case that constantly torment us and cause us dismay in our everyday lifes. When Beowulf is at the feast when he arrives at Heorot he is sitting at a bench when the helming woman came by to give him a absorb with measured words she welcomed the Geat and thanked God for granting her wish that a deliverer she could believe in would arrive to ease their afflictions. (625 628) When she tells h im this it gives a kind of Godly presence to Beowulf that he is their savior and he will relieve them of their transgression that is Grendel and his murderous ways. In the beginning of the story it talks about how a leader will come one day that would be set apart from others that had come before to deliver the Danish people from all their problems. It also states that the shield was still live(a) when it was the mans time to go into the lords keeping. Shield was still thriving when his time came and he crossed over into the Lords keeping. (26 27) This is symbolic of how the shield is Gods word and Gods protection over us how when we have it with us in our lives we will be taken by him when our time comes to spend eternity in his kingdom. Another interesting symbol in the story is Grendel the story often refers to him as God-cursed (711) which is similar to the devil who was banished and cursed for the rest of eternity just as Grendel was as he was always donjon in torment and al l that would ease him is the pain and suffering of others such as when he arrived at Heorot and saw all the men sleeping there. his glee was demonic, picturing the mayhem before morning he would rip life from lib and devour them (730 732) Grendel enjoyed causing misery in the lives of the Danes much like the devil enjoys beholding suffering in our lifes.Beowulf is an amazing story that teaches us courage, it shows us characters such as Beowulf himself that are true to his word and self-confident, and it also shows us symbols that give an image of God and the hope that he brings to the people that believe in his word. Whether its courage or just teaching us to believe and trust in God through any transgressions that we encounter in life Beowulf can teach us many valuable lessons that can help make us get around people.

Effect Of Exercise On Arterial Blood Pressure

Effect Of employment On Arterial rake closetThe aim of this look into is to investigate the effects of several(predicate) intensity of employment on perfume pasture and arterial countercurrent pressing in young healthy gentleman subjects.Jumping jack go is used in this experiment by increasing the frequency of jumping which are 5, 10, 20, 25 and 30 cycles continuously for 5 sessions. The HR and BP were measured in the beginning and by and by the exercise for the study of opening. Data showed that there is an augment in HR and BP among the subjects. Furthermore, with increasing intensity of exercise, the difference amongst the values before and after exercise also profitd. However, diastolic agate line press did not show all signifi brush asidet difference.The cardiovascular system is make up of the total and circulatory system. The magnetic core meats alliance to the organs, tissues, and cells of our body. Oxygen and nutrients are delivered by the crosscurren t to every cell of the body. On the another(prenominal) hand, carbon dioxide and decompose materials are re imprintd by the blood line. It is important to understand the cardiovascular system in order to fully comprehend the physiological effects of exercise on the human body.1The illustration shows the front surface of a heart, including the coronary arteries and major blood vessels.The heart is a myogenic muscular organ which acts like a pump to continuously send blood to our body cells. It has the shape of an upsided pear. The heart is located between the lungs in the middle of our chest. It has a double-layered membrane c onlyed a pericardium. The pericardium acts to protect the heart. The out pericardium layer is attached by ligaments to our diaphragm and other parts of our body. The inner pericardium layer is attached to the heart muscle. there exists a coating of fluid separating the deuce layers of the membrane. This allows the heart to move as it riles and yet still b e attached to our body.3In this project, we would like to study the effects of exercise on heart set and blood force. The lawted hypothesis is that exercise get out cause an summation in heart regularise, an ontogenesis in systolic blood bosom and a slight decrease or somewhat constant diastolic blood nip.Heart enjoinHeart rate is delineate by the function of heartbeats per unit time, in comminuteds. The heart rate of a human world may change depending on the need for oxygen. When oxygen dependency increases, the heart rate increases. When oxygen dependency decreases, heart rate decreases. Heart rate is measured by counting the pulse of the body.4Blood pressureBlood pressure is defined as the force applied on the walls of the arteries as blood is pumped throughout the body. obligate is determined by the force and enumerate of blood being pumped and also determined by the size and flexibility of the arteries. Blood pressure is affected by many factors such as the ind ividuals daily routine, diet, stimulated state and posture.5Blood pressure is measured by a device called the sphygmomanometer. It measures the magnitude of pressure necessary to block blood flow through an artery. Pressure is applied by the sphygmomanometer which cuffs a persons arm.6The ideal blood pressure is below 120 over 80 (120/80). The systolic pressure is the payoff above and the diastolic pressure is the come below. Systolic blood pressure is defined as the blood pressure when the heart is contracting. Specifically, it is the highest arterial pressure during contraction of the left wing heart ventricle. Diastolic pressure on the other hand measures the pressure exerted by the heart when the heart is at rest.The mean arterial pressure is the average blood pressure of an individual. It can be determined by the following formulaMAP = DP + 1/3(SP DP)7SP = Systolic pressureDP = Diastolic pressureProtocolFrom the group of 14 individuals, one individual is selected to take measurements of blood pressure and heart rate of the remaining 13 individuals. The 13 subjects consist of 3 males and 10 females, with an average BMI of 19.49. Firstly, the heart rate and blood pressure of the first individual was measured. Then, 5 cycles of the modify jumping jacks were performed. After the 5 cycles of exercise was performed, the subject was required to sit in an upright position, where blood pressure and heart rate was measured. The subject was also given 3 minutes as resting time. After the resting head, the first individual carried on with an increment of 5 cycles of the same exercise up until 20 cycles.(i.e. 5 cycles, 10 cycles, 15 cycles, 20 cycles) This was through with(p) with the remaining 12 subjects.StandardizationAnticipatory periodall(a) subjects were required to sleep at least 7 hours before the day of the exercise. No caffein and alcohol diet has to be consumed 3 hours before the exercise. Subjects were required to eat one banana and one energy ba r cracker 3 hours before the exercise was conducted. Proper sports attire was worn by all 13 participants. 5 minutes of resting period was given to each subject. Subjects were required to sit in an upright position while resting. Hand phones were switched off to avoid interruptions while doing exercise. Laughing and eating are prohibited during exercise for more accurate readings. Lastly, all subjects were in good health during exercise and are not under influence of any drugs.Exercise periodDuring the exercise, activities such as laughing, talking and mobile movements are not allowed. All candidates must keep their men straight while doing jumping jacks, and must squat completely throughout the vogue of the exercise. The beat of the metronome was set at 84 beats per minute.Resting periodAll subjects were not allowed to consume any beverages and no other movements were allowed except the exercise mentioned. A resting period of 3 minutes was given to each subject. The same stopwat ch was used to measure the resting period.Heart rate and blood pressure measurementOnly 1 person was assigned to measure the blood pressure and heart rate of the 13 participants. Initial heart rate and blood pressure was performed 1 minute before the exercise was conducted. After conducting the exercise, heart rate and blood pressure was measured immediately. The heart rate was measured first followed by blood pressure. All subjects were required to sit in an upright position while getting their heart rate measured. The same sphygmomanometer and stethoscope were used to measure the subjects blood pressure.Methods to measure heart rate and blood pressureHeart rateFirstly, the palm side of the subject was turned facing up. The index finger was placed on the articulatio radiocarpea of the subject, approximately 1 inch below the base of the subjects hand. The index finger is pressed down in the grove between the middle tendons and outside bone. A throbbing pulse should be felt. The num ber of beats was counted for 30 seconds, and multiplied by 2. This will give a heart rate of 1 minute.8Blood pressureThe sphygmomanometer was inflated to a little above 180mm Hg. This collapses the major arteries of the arm. Air is released by turning the air valve. The pressure should drop. When the first throbbing sound was heart, the systolic blood pressure was recorded. The sound heard following the first throbbing sound is the sound of blood flowing through the artery of the arm. This means the systolic blood pressure is higher than the pressure in the blood pressure cuff. The air valve continues to be released until no sound is heard. When no more sound is heard, the diastolic blood pressure is recorded.10Exercise descriptionFirstly, both feet are put together, with hands down on both sides. Candidates are required to jump to move both feet apart while both hands are raised 90 degrees from the body. They are required to jump again to move feet together and need both hands tog ether over the head by clapping. The exercise subjects then return to the 2nd position, where both feet are apart and both hands are 90 degrees from the body. Next, candidates then return to the initial position. Lastly, the candidate is required to squat once and then return to position one. Only after playacting each of these steps is one cycle considered.PreparationBanana, energy bar cracker, metronome and stopwatch were prepared before the experiment.Type of exerciseThe exercise is a modified version of jumping jack. All subjects were required to complete the exercise based on the speed set by the metronome.Test subjects3 male and 10 female students were chosen to carry out this experiment. The subjects are healthy individuals who do not smoke and do alcohol. The mean body weight was 57.69kg and the mean peak was 165.19cm.Location of exerciseIMU, Skills Centre.ApparatusSphygmomanometer, stethoscope, stopwatch and metronomeInterpretation of forcesStatistical testThe one-way AN OVA turkey test was used to determine whether there were any difference in systolic blood pressure, diastolic blood pressure, heart rate and mean arterial pressure between the number of cycles of exercise.Null hypothesis There is no difference in heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure before and after exercise.Alternate hypothesis There is a difference in heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure before and after exercise. (Heart rate, systolic blood pressure, and mean arterial pressure increases, diastolic blood pressure remains the same or decreases slightly)Result interpretingFrom the results for table 2, it can be seen that the rate of heart rate increases when the number of cycles of exercise increases. Statistically, from the one-way ANOVA turkey test, the calculated p-value for heart rate was lesser than 0.05. If the calculated p-value was lesser than 0.05, this implies that ther e is a significant difference in heart rate between the number of cycles of exercise. From the graph obtained in figure 1, it can be seen that the heart rate increases steadily when the number of cycles of exercise increases.From the results for table 3, the result is similar to the result of table 2. Systolic blood pressure increases when the number of cycles of exercise increases. From the one-way ANOVA turkey test, the calculated p-value for heart rate was also lesser than 0.05. This implies a significant difference in heart rate between the numbers of cycles of exercise. From figure 1, it can be seen that the heart rate increases steadily when the number of cycles of exercise increases.From the results for table 4, the diastolic blood pressure decreases when the number of cycles of exercise increases. From the one-way ANOVA turkey test, the calculated p-value for diastolic blood pressure was also lesser than 0.05. This implies a significant difference in diastolic blood pressure between the numbers of cycles of exercise. From the figure, it can also be deduced that diastolic blood pressure decreases, however only slightly when the number of cycles of exercise increases.From the results for table 5, the mean arterial blood pressure seems equal throughout the cycles of exercise. When calculating the p-value using one-way ANOVA turkey test, the p-value was higher than 0.05. This implies there is no significant difference in the mean arterial blood pressure between the numbers of cycles of exercise. From the figure, it can also be deduced that the mean arterial pressure doesnt afford any change as the number of cycles of exercise increases.DiscussionEffects of Aerobic Exercise on Heart RateThe heart rate for an individual is 60 to 100 beats per minute. Heart rate per minute will increase depending on the frequency of physical activities the individual carry out. During exercise, muscles undergo aerobic respiration which requires constant oxygen supply. This i s because the level of carbon dioxide in the blood increases due to the rising cell respiration of the muscles. Thus, the lack of oxygen results in a huge rush of oxygen ingestion through the lungs. An impulse is then move to the sinoatrial (SA) node which causes the heart to beat faster. The increased oxygen intake activates the oxidation of lactic acid into carbon dioxide to be carried away. As a result, the muscles will produce the most amount of energy per mole aerobically.10Oxygen, carbon dioxide and atomic number 1 ions (H+) are detected by chemoreceptors which are located at the medulla oblongata and parts of the peripheral nervous system. When exercising, H+ increases due to the excess carbon dioxide. A rise in H+ concentration activates the chemoreceptors which in turn send impulses to the inspiratory centre to increase breathing rate. Hence, heart rate increases. On the other hand, the lack of oxygen also causes a rise in breathing rate. The peripheral chemoreceptors ar e activated when large oxygen is reduced. Signals are then sent to the inspiratory centre to increase the breathing rate, and thus heart rate.11 similarly, lactic acid which dissociates into lactate and H+ during anaerobic respiration when exercising also results in a rise is H+ concentration. This in turn increases the heart rate by the same mechanism discussed above.12Heart rate can also be altered by autonomic nervous system. Stimulation of the sympathetic nervous system causes an increase in heart rate as well as other factors such as stroke slew and systemic vasoconstriction.13 The stimulated sympathetic nervous system also acts to release glucose from the liver for energy. During exercise, heart rate rises rapidly due to the activation of sympathetic nervous system.14Apart from that, the stimulated sympathetic nerves also release catecholamines such as epinephrine and norepinephrine. They ferment to cause the heart to beat faster by increasing the depolarization of sinus nod e. This increase of heart rate is known as tachycardia.15 Furthermore, the contractility of the heart muscles will also increase through binding of catecholamines with alpha-adrenegic receptors on the smooth muscles.16The parasympathetic nervous system opposes the sympathetic nervous system which slows the heart rate oddly when physical exertion such as exercise is over. This is due to the release of hormone acetylcholine which hyperpolarizes the membrane and inhibits heart rate. The slowing of heart rate is known as bradycardia.17 When resting after strenuous exercise, both autonomic nervous systems still work continuously to send impulses to the SA node. However, inhibitory is dominance over excitatory. As a result, pneumogastric tone is said to be exhibited by the heart. In addition, if the vagal nerves are not innervating the heart, the heart rate will be slower than it would be.16, 18Other than that, atrial reflex or known as Bainbridge reflex is initiated during exercise. Th is reflex involves in increasing the venous return and blood congestion in the atria. By stimulating the SA node and baroreceptor in the atria, the atrial walls are stretched which add on to the force as well as heart rate. As a result, the reflex action leads to a rise in sympathetic stimulation of the heart which in turn increases the heart rate.19Another factor which contributes to an increase in heart rate is the body temperature. Metabolic rate increases during exercise. This causes the body temperature to rise when the metabolism in the body release energy as heat.15Consequently, sympathetic siding at the heart will increase due to the impulses sent by the thermoreceptors to the somatosensory cortex and thus heart rate increase.18Effect of Aerobic Exercise on Systolic Blood PressureIn this experiment, 13 subjects were required to perform a modified version of jumping jacks at polar intensity levels. The exercise was performed in cycles where increased cycles of jumping jacks will increase the intensity of the exercise.The mean blood pressure of an individual depends on the amount of blood flow from the heart throughout the body and the net guard of blood flow in the arteries of the body. Blood pressure is calculated via the following formulaBP = CO x PVR where,BP= blood pressureCO= Cardiac OutputPVR=Peripheral vascular resistanceDuring exercise, exercising muscles produces more carbon dioxide, thus this increases the blood partial pressure of carbon dioxide (PCO2) in the human body. As PCO2 increases, the need of oxygen intake into the human body increases. Oxygen use increases when PO2 decreases. Since oxygen is carried by the blood in the form of oxyhaemoglobin, therefore, the body would need to pump in more oxygen to accommodate for the lack of oxygen.20From the equation BP = CO x PVR, increase in cardiac rig increases blood pressure. As systolic blood pressure is the pressure when the heart is contracting, therefore the systolic blood pressure s hould increase with increasing exercise.During exercise, the systolic blood pressure of each experiment subject is seen to be increasing throughout each cycles of the exercise. From the table, it can be seen that the mean systolic blood pressure increased from 106.5 at resting blood pressure up to 135.5 when the exercise was conducted at 20 cycles. Thus, the experiment supports the claim that exercise increases systolic blood pressure.Effect of aerobic exercise on diastolic blood pressureDiastolic blood pressure is the blood pressure when the heart is relaxing. It is the blood pressure of our artery walls between heart beats. Diastolic blood pressure is affected mainly by blood volume, stroke volume and heart rate.21Stroke volume (SV) is the difference between end-diastolic volume (EDV) and end-systolic volume (ESV). It is related by the following equationSV = EDV ESV22EDV is the volume of blood before the heart contracts and ESV is the volume of blood left in the heart after it co ntracts. Therefore, SV is the net volume of blood pumped out by the heart in 1 heart beat. During exercise, oxygen consumption increases, therefore the amount of blood needed to pump throughout the body also increases, therefore stroke volume increases during exercise.During exercise, the temperature of the human body increases. When this happens, the body undergoes veto feedback by dilating the arteries in the body. Vasodilation happens to increase the blood supply to around the tissues and also to take away heat from the body. Therefore, during exercise, cardiac output increases whereas peripheral vascular resistance decreases due to vasodilation. Thus, this causes the diastolic blood pressure to remain fairly constant throughout, or decrease slightly.From the experiment, the diastolic blood pressure decreases slightly over the course of exercise. As exercise was conducted, vasodilation could explain the lowering of diastolic blood pressure throughout the exercise.Effect of aerob ic exercise on Mean Arterial Pressure (MAP)MAP is the average pressure of blood exerted on the walls of the arteries during the whole cardiac cycle. MAP is the product of cardiac output and total peripheral resistance. During exercise, cardiac output increases to meet the metabolic needs of skeletal muscles.23Total peripheral resistance on the other hand decreases due to vasodilation of blood vessels. However, total resistance of systemic circulation is kept constant due to constriction of arterioles in visceral organs such as the kidneys and gastrointestinal tract. Therefore, MAP increases in exercise due to the large increase in cardiac output.7The equation to derive mean arterial pressure is as followMAP = DBP + 1/3 (SBP-DBP)7Throughout the exercise, systolic blood pressure increases dramatically whereas diastolic blood pressure remains fairly constant or decreases slightly. Therefore, this elevates mean arterial pressure. From the experiment, the mean arterial pressure is fairl y constant throughout the experiment. This could be due to the inaccuracy of the measured diastolic blood pressure. Besides that, the exercise could also be switched into a stress test, where subjects are required to perform physical exertion to their limits. A stress test could clearly show mean arterial pressure difference because cardiac output would be at its maximum.From the results obtained, it can be seen that the mean arterial pressure is fairly constant throughout the experiment. This could be due to the inaccuracy of the measured diastolic blood pressure. Besides that, the steady decrease in diastolic blood pressure could also override the increase in systolic blood pressure, thus causing the result of mean arterial pressure to remain constant throughout the experiment.LimitationsDue to the limitations of the experiment, the obtained results were not that consistent and accurate when compared to the theoretical results.First of all, the sample size is alternatively too sm all and insufficient for statistical interpretation as it consists of just 13 members in the experiment.Gender factor affects the obtained results too. This is due to the imbalance number of females and males in the sample which is 2 males and 11 females. As different genders have different metabolism rate, this contributes to unwanted errors in the results. 10Other than that, the resting period in between each set of experiment was inadequate due to time constrain. The heart rate and blood pressure were not allowed to return to the resting level before the event experiment is carried out.In addition, due to two different people in measuring the heart rate and blood pressure, it leads to variations in determination of the final readings of the results. There might also be confusion of auditory and visual cues especially when hearing for the diastolic pressure.Further StudiesIn order to improve the studies, a big sample size can be used to increase accuracy of the results. When a l arger sample size is used, more comparisons can be do between the differences of genders, age, BMI, as well as the frequency of exercise.Besides, the time of the resting period can be modified to be longer. This is to ensure that the heart rate and blood pressure have returned to the resting level before the next set of experiment starts in order to reduce the inconsistency of the results.ConclusionFrom the experiment, the results show that there is an increase in heart rate and systolic blood pressure. However, diastolic heart rate showed a decrease. Calculated mean arterial pressure(MAP) remained constant throughout different exercise intensity. However, this could be due to several reasons discussed as of above.

For Another Mans Freedom :: essays research papers

For A nonher Mans Freedom"All men argon created equal", alone the men this is pertaining to are nonthe men losing blood in this battle at Gettysburg. The men losing their livesin this war are men chip for what they believe in, for the benefit of theirsuggested equals. Stepping forward, and thusly looking back these memories, andthe impact these memories have, are not and will neer be forgotten.     The blood which was shed in this great battle at Gettysburg could neverbe forgotten. The blood being spoken of by Abraham Lincoln, was thought bymany to have recycled into the earth, therefore making that ground sacred also emanation to heaven. This battle ground and the battle which occurred here isbe recognized by the people of United States of America as the "rebirth" ofAmerica. The only problem with these thoughts is that these were not thethoughts that were in the heads of the soldiers at the time. During thefighting these soldiers not only di d not see this as the rebirth of a nation,but had "forgotten the cause" altogether. I do not believe that these men werenecessarily fighting specifically for the rights of the slaves, but rather forthe rights of all men including themselves. These men were thought to be"privileged", and at the time I am sure they believed that they were taking partin an inconceivable historical event. I am sure that at that time they did notrealize that this would be an ongoing struggle even three-hundred years aftertheir existence. The soldiers entered this battle with great pride, holdingtheir flags high, hoping to make a difference. They did make a clearlysubstantial impact on their society , but this quest for equality is still beingpursued.This fight was not considered the only option at the time, but peacefultalks were always considered. As society knows, peace talks are not always thebest way to get through to a person opposing your views.     While discus sion in hopes of no war exist, war is already being plannedwithin the rights of an individuals mind. In the Killer Angels supplement, the glorious depiction of the war grounds is harshly interrupted by the grimcommencement of the fighting. These men, through their devotion to theircountry, were proud to stay either until they died, or until the fighting hadceased. Many references to God are made in this Second Inaugural Address, andthese references are also made in the Killer Angels. The soldiers in the battle

A New Sense Of Life :: essays research papers

A New Sense of LifeIn Baldwins discovery of What it Means to Be an Ameri bear, it was said that to be an American was a rattling free feeling. The f hazard is you could change yourself mid- conduct and still hold worth and prowess. The idea of world considered a great(p) author, and also as being a great actor, holds different places here in America then in Europe, or up to now Canada. Most places would hold the profession of an author to have more of an refinement then an actor. The author holds more intellectual ground, then that of one who can act out a part and memorize lines. (Not so much as the idea of being a writer, then an actor, but how you present yourself.) If someone asks you, Who atomic number 18 you?, you might simply answer, I am a carpenter. or I am a congressman. Say you have a job that would not be as high on the social ladder as these. For example, using up the profession of a garb historic period man. He gets paid as much as the carpenter, but in society, that profession isnt looked upon like a carpenter, or a congressman. Along the same lines, a congressman, or even a carpenter, can turn around at the pinnacle of his career, and choose to be a garbage man, if thats what his heart ingestks. America has a view unlike each other nation, in which you can start over at every time. You can take control of your life by going back to school, cultivation what you desire to, thus becoming something completely different at the age of 50. Unlike many eastern nations, where you are dedicated to that one job concept, (IE. If youre an incredible trumpet player, you will be that for the rest of your life, and thats that), in America you have the option to move about in the job market, to pick up out different professions, and feel your way through life. You can see evidence of that by the fact junior colleges are very popular among elderly people. In America, you are allowed to go to school for the rest of your life if you want to, and the sc hool will work around your current employment schedule. The meaning of life in America is different than that of any other country. You can go where you want and be whomever you want.A New Sense Of Life essays research papers A New Sense of LifeIn Baldwins Discovery of What it Means to Be an American, it was said that to be an American was a truly free feeling.
