Farley, Mowat’s “Never cry wolf” Essay

Farley, Mowat’s â€Å"Never cry wolf,† is a book based on the research of the lifestyle of wolves in the Arctic Circle. Mowat uses his experience to educate the society of the social ills conducted by the hunters towards the wolves. The book displays the risk that the wolf pack families face due to the human activities in the area. The title of the book acts as a symbol in reference to the story of the boy who cried wolf. The book thus enables the reader to think beyond the tile so as to form an opinion of the author’s message. The book challenges the human communities who are in charge of the nature around them. Humans tend to overstep their authority by infringing on the rights of the wolves. The analysis of the book educates the society of the inhumane activities that humans are inflicting on the animals. Different passages from the book Interpretation of the passage and meaning I was born and grew up in the farm and never knew what it was to have all I wanted or needed as a teenager in the late 20s The author talks of his life as a child. He was exposed to animals at an early stage in life due to his parent’s lifestyle. This is a contributing factor to his love for animals. That night the inevitable happened. We were awakened by the most frightful uproar. It seemed to consist of furious barking of a dozen dogs mingled with the roaring of the menagerie of lions The passage elaborates the intensity of the nature that surrounds him. The conflict between the dogs and the lions displays the fight for power amongst the animals. Then there were the birds. That spring Angus had bought me a field guide and with its help, I identified forty species that were new to me. The author’s exposure to different bird species enabled him to identify with the different lifestyles that they had. Angus developed a love for all forms of wildlife which in turn made him aware of the plight that the animals had. My most cherished images of the mountain country were not of the forbidding peaks but of the animals The author admits that he has a special place for the animals. The country has a number of natural resources that are fascinating to any visitor. Amongst all these features, he places priority on animals making them his favorite pastime. Although I would now commit such atrocities against some of the most beautiful creatures extant, I cannot honestly censor the boy who was for what he did then The author admits that his actions are reflective to that of other men. His treatment of the animals is not desirable initially. He learns how to appreciate all sorts of animals making him an advocate for their livelihood. â€Å"The wolf is a savage, powerful killer. It is one of the most feared and hated animals known to man and with excellent reason† Chapter 6, pg. 60. The passage showcases the dangers that the wolf portrays. Human beings often misinterpret the actions of the wolf due to its dangerous nature. Despite the fact that the wolf continues to become extinct, it poses a threat to the human beings who live next to the packs. This makes the world undesirable by man. â€Å"Evidence obtained by various Government agencies from hunters, trappers and traders seemed to prove that the plunge of the caribou toward extinction was primarily†¦ The intervention by the government saw the danger that the wolves are exposed to. Human activities were mostly responsible for these dynamics making them the number on culprits. This also displayed possible extinction of the breed of wolves if authorities continued to ignore the circumstances. â€Å"I had made my decision that, from this hour onward, I would go open-minded into the lupine world and lean to see and know the wolves, not for what they were supposed to be, but for what they actually are† Chapter 7, pg. 77. Morwat made a personal decision to protect the wildlife from the outside environment. One of the steps he takes is orienting himself with the lives of the wolves. This involves learning about the exact nature of the wolves instead of forming an assumption about them. This in turn will help remove the ignorance that he had so as to improve society’s awareness of the wolves. In conclusion, human beings are responsible for the surrounding environment. This involves observing the safety of all animals in and outside the wild. This is however, not the case in that the number of wild animals continues to diminish due to the human activity. The wolves are one of the animals that continue to face the wrath of human beings. The analysis of the book is thus ideal for the education of the public. This in turn will improve the existing relationship between man and nature.

Test the heart rate of a number of pupils while they were taking part in a `stepping activity`

Aims: To arrange pupils who took part in the exercise in order of fitness level. I will look at who is the fittest and see why, and also see if there are different fitness levels between girls and boys within the group. Method: The information that I have been given is that eight pupils, four of each sex took part in a stepping activity, their height and weight were recorded, the heart rate of all pupils before the activity, the heart rate of all pupils at regular intervals during the activity and the heart rate of all pupils 10 and 20 minutes after the activity. The way in which the pupils who carried out the investigation took the measure of heart rate was in the following way; each pupil in turn was connected to a BBC heart rate monitor and then asked to step up and down for ten minutes. Their heart rate was taken every 2 minutes. The pupils were then asked to rest. Their heart rate was taken again 10 and 20 minutes after the exercise had been completed. Background Information: There are many measures of fitness. For example the volume of blood, this is very important. The red blood cells contain the haemoglobin that reacts with oxygen. There are about 5.5 million red blood cells in each cubic cm of blood in a healthy adult. So the larger the volume of blood, the more oxygen is transported in a minute. So it is vital to have the requested amount of blood as that oxygenated blood which contains the oxyhaemoglobin, is that one that transports the oxygen to the cells, in this case the muscles exerting the force will be in most need to oxygen. Another thing that will affect the efficiency of the pupils in the exercise is how big the lungs are. If the lungs were big, they would have a large volume of air because the diaphragm and external intercostals muscles are larger and therefore create a larger volume when they contract; this is advantageous since they supply the increasing amount of oxygen to the blood passing through. When a person exercises, the level of carbon dioxide in blood increases and this is toxic. This increase in the level of carbon dioxide in the blood is detected by the chemoreceptors, which send messages to the medulla oblongata, which in turn sends messages via the nerve fibers to the intercostals muscles, and diaphragm making them allow larger volumes of air in and because of that breathing rate increases. So the bigger the lungs, the more carbon dioxide they can take out from the carboxyhaemoglobin as they inhale. Until this point its all aerobic respiration but when it gets to the point when the heart can't cope with the increasing demand for oxygen, the muscles will not get enough oxygen to react with glucose to create the energy to make adenosine triphosphate (ATP) which is then used as an `energy currency` to `pay` for these changes in a cell which require energy, the cells start to break down what it can from the glucose to create little energy without the presence of oxygen, this is called anaerobic respiration as it doesn't need oxygen and doesn't produce carbon dioxide and water but instead Lactic acid. So no matter how fast you breathe or how fast your heartbeats, your body cannot obtain enough oxygen from aerobic respiration to supply all its energy needs. So although your muscles will get the energy they need, this lactic acid will start to collect in the muscles, which changes the blood pH, which also makes your muscles ache. So at the end of the exercise, the heart would have reached its limit in some pupils. The limit is when the heart is pumping as fast as it can and all the oxygen in the arterioles is taken and most of carbon dioxide is given to the venules. Within a minute, there will be too much of this acid that your muscles stop working altogether. So build up of lactic acid affects performance. You then will be breathing deeply after the exercise to repay the oxygen debt, which is the amount of oxygen needed to get rid of the acid. The heart is a muscular organ, so the cardiac tissue develops more strength with increased use so therefore when someone exercises that will make the heart more efficient and increases its size. So when the muscle develops the heart will pump more blood in each beat. This means that the heart can beat less frequently and still pump the same amount of blood. So the stronger the heart the fitter the person is. Now I am going to represent the information that I have been given in a series of graphs and charts so that I can analyze them and evaluate the procedure. Analysis: Graph number 1 shows the heart rate of all the pupils before, during and after the activity. A resting pulse is the pulse that you have when you are relaxing and not doing any exercise and doing your normal body functions. So when you compare the resting pulse of the pupils you notice a difference, this is because some pupils have stronger hearts. So low heart rate indicates strong cardiac muscles, which may be inferred that person is physically fit. Graph number 3 shows that the boy's average heart rate is higher than the girls; therefore I can assume that the heart muscle of the girls is stronger within this sample. During the exercise phase all the pupils' heart rate goes up because there is a greater demand for energy, which is met when the heart supplies blood carrying oxygen and glucose necessary for respiration. Due to the strengths of the hearts, some of the pupils are only able to sustain the effort for only a short period of time and others for longer. The heart rate goes down after the pupils stop exercising because there is a less demand for oxygen in the muscles, and so the heart is able to cope with that easily and therefore it doesn't need to beat as frequent. You do realize that at the 10th minute the exercise is over, after the 10th minute, the graph shows the recovery time of all pupils. The recovery time is the time a pupil takes to recover from the end of the exercise to return back to the resting pulse. I have drawn a separate graph for the recovery time, as this time is an important sign of fitness. The shorter the time the fitter the person is because the person hasn't got much of oxygen to pay back to get rid of the lactic acid. This shows that hisher heart copes well with the increasing demand for oxygen. From graph number 2 you can see that Anne and Daljit have the shortest recovery time, which is also identical i.e. 20 minutes, the longest recovery time is Jane's which was 30 minutes long. So she took a while to repay the oxygen debt, her heart is not strong as the others, because it needed to keep pumping frequently to get the required amount of oxygen to where its wanted. Also the bar chart shows that the boy's recovery time is slightly higher than the girls' recovery time. The boys have an average of 19.5 and the girls have an average of 21.5. These averages are not accurate because we have not been given accurate information, as the pupils who took these measures, didn't take them at narrow time intervals. So looking at these averages in addition graph number 3 showing pulse rate of boys verses girls which tells us that girls in this group have stronger cardiac muscles than boys for this sample. Summary: I conclude that Anne is the fittest pupil for a number of reasons. Anne has the lowest resting pulse and during the exercise her pulse rate stays the lowest, which means that she has got strong cardiac muscles, she has a very fast recovery time, which shows she is fit, and she is also physically fit because she has strong leg muscles. For the same reasons I will place the others in order of fitness level being the fittest at the top: 1. Anne 2. Daljit 3. Rhona 4. Marj 5. Jane 6. Sean 7. Aaron 8. Stan Evaluation: I am going to evaluate the experiment in the following way: the aim of the experiment is to find out who is the fittest and if there was any difference in fitness levels between boys and girls, but this experiment only experiments the stamina, and fitness involves all the S-factors which are strength, speed, stamina and suppleness. So they must cover the other three aspects. For strength they could have done some press ups. For speed they could have done a race. For suppleness they could have told the pupils to stretch themselves as much as they can. They also could have taken the pulse of the pupils at intervals of 2 all the way through the exercise till the pulse returns to the resting pulse instead of taking the pulse at intervals of 10 after the tenth minute. This way it would be easier to work the recovery time and the time would be more accurate. Also the sample size was not enough to support any conclusion that any sex is fitter than the other, therefore I would use a sample of at least 30 pupils of each sex. They should have got some more background information about the pupils and their health status. They could have done the exercise twice so the results are more reliable. The pulses taken were accurate because they connected the pupils to a BBC heart rate monitor. While some of the pulse rates appear to be anomalous, we can be sure of their accuracy due to the way they were recorded. Our interpretation of these is skewed as we have only 2 other data points to consider. These are discrete measurements determined by a wide range of continuous variables. On basing our conclusions upon these points we have to remember the underlying determining variation and that these factors have an influence on pulse rate.

Ancient Rome Essay Example for Free (#2)

Ancient Rome Essay During the Han Empire of China and the Roman Empire of the Mediterranean World were both had advanced technology for their time. Han China’s attitude toward manufacturing and labor was more positive than the Romans who had a more class divided society, therefore causing attitudes toward labor and technology to be looked down upon. The Hans respect technology and the people who use it. In China, 2nd century B. C. E. a government official stated that he wanted to organize their labor force with the use of technology so they could help to prevent a disaster from occurring when and if a flood takes place. This could help the people from getting hurt and their property from getting destroyed (Doc. 1). Huan Guan, a Han government official during the first century B. C. E. was concerned about the lack of technology and poor government policy that is affecting the people. Haun Guan was trying to say to the Han government that using convict labor to make tools and monopoly on salt and iron is causing devastating affects towards the people and feels that the government can solve this problem by using the available technologies. Even though Haun Guan is a government official himself, he shows interest in helping the people and is very critical towards the current government policies that are in place (Doc. 2). Huan Tan, a upper class Han philosopher during 20 C. E. is expressing his appreciation of the progress that technology has had since the emperor’s first invention . Huan Tan also expresses how technology has benefited the Chinese people and feels that technology is a â€Å"gift† from the enlightened emperors (Doc. 3). A Han government sponsored speaker, around 200 C. E. states how a Han governor, Tu Shih, cared deeply for the Chinese people and used the advanced technology to help benefit them. This government sponsored speaker emphasizes how much the inventions helped minimize the amount of human labor that the people did (Doc. 4). This is interesting because he was hired by the government to talk to people who might be losing faith in the Han Dynasty and he basically glorified the information way more than it actually was. On the other hand, the Romans felt that working with your hands was vulgar and seemed to heavily look down upon technology and whoever used it. Cicero, an upper class Roman political leader from Italy during the 1st century B. C. E. states that anyone who works with their hands are vulgar and looks greatly down upon craftsmen and hired workers. Cicero then goes on stating that â€Å"gentlemen do not work with their hands. †(Doc. 5) It seems that Cicero lacks a huge respect for inventions and inventors and feels like technology is indeed necessary, but not for the â€Å"enlightened minds†. Plutarch, a Greek born roman citizen during the 1st century Roman Empire, expresses Gaius Gracchus’ road building enterprises and continues to explain how the Roman upper class does appreciate technology that benefits the upper class (Doc. 6). Plutarch does show appreciation towards technology, but only because it benefits himself, as well as the rest of the upper class. He does not go on to mention how it helped the commoners in any way, because it most likely didn’t help anyone but the upper class. Seneca, an upper class philosopher and advisor to Emperor Nero, from the 1st century Roman Empire, states that it takes someone nimble and sharp to make inventions but craftsmen don’t have great minds. Seneca goes on to say that he does â€Å"not believe that tools and crafts were invented by wise men† (Doc. 7). Seneca lacks respect for craftsmen and is basically saying that they are not as smart as he is, and degrades their achievements and abilities that they have. He isn’t concerned about any of the tools or inventions that are made by these craftsmen because he feels since he is an upperclassmen, he would never use them for the fact that they would be degrading to his specific class in society. Frontinus, a Roman general, governor of Britain, and water commissioner from the 1st century C. E. of the Roman Empire discusses how he praises the Roman aqueducts and their uses in Rome. He talks about how intelligent the designs are and how much it benefits the public (Doc. 8). It was quite interesting how highly was talking about the aqueducts. He talked about how amazing they were to the other Roman officials so they could see he was doing a good job as water commissioner, which is why he talked so highly of the aqueducts, because that’s his job. A point of view that is missing from these documents that could further help to the discussion of the Han and Rome attitudes towards technology would be the commoners. All eight of these documents were of the point of view from government officials or other upperclassmen. It would’ve helped to see an argument made by the commoners from both empires because that’s who the technology is affecting-the commoners. Although the technology is also affecting the upperclassmen, it would have made a better argument to have someone who is more â€Å"exposed† to the technology in their everyday lives. The people of the Han Empire did have a more optimistic approach towards technology, while the Roman Empire looked at technology as a more negative thing. The Hans took more into consideration of how it would benefit the commoners, unlike the Romans who didn’t mention the commoners in any of their arguments. Although both Empires did use technology, some thought more highly of it than others. Ancient Rome. (2017, Jan 01).

Executive Pay Essay Example | Topics and Well Written Essays - 1500 words

Executive Pay - Essay Example While there is diversity across industries, sizes of organizations and countries, executive pay includes the common features of base pay and bonus based on performance. CEO compensation has become one of the most important issues of concern in the field of corporate governance. With ever increasing economic activity and companies transcending all boundaries, geographic, economic and technological, the person in charge of steering the company has been thrust into focus. Typically, huge compensation packages were a phenomenon of the golden days of dotcom glory. The period of Internet boom may safely be termed the era of exorbitant pay-outs. The Internet made millionaires of people in a matter of days. In the Internet-rush' of the late 1990s, a number of small companies mushroomed redefining the principles of economies of scale and scope. The CEOs (as well as the employees) of dotcoms often burnt the midnight oil trying to float their talents. For their efforts, they were compensated handsomely, when the company took off and reaped rewards. However, even after the burst of the Internet bubble and the decline of the software industry from its top position on the list of the most happening industries, huge pay-outs have remained. A quick recap of the origin of CEOs will give us a better understanding of the topic. When economic systems evolved from sole proprietorships to the company form of business, a need for a distinction between the owner of the resources and their managers arose. In some cases, owners stopped playing an active role in managing the business resources and turned them over instead to paid managers. These paid managers acted as agents of the owners and took up the responsibility for the success or failures of the business. As businesses grew in size and scope, the manager attained the glorified title of a CEO. The compensation system also became more complicated, evolving from a simple salary to benefits like bonus, perks and stock options. As time passed, the compensation packages grew in size until t hey attained such astronomical proportions that people began feeling the need for some control. This leads us to the question of whether CEOs merit the huge compensation they receive or not. In the US, historically, CEO's in "utilities earn significantly lower levels of compensation than their counterparts in other industries, while CEO's in financial services earn higher pay" (Ashenfelter, et al, 1999, p. 5). Yet the relationship between firm size and executive pay is weakening. A comparison of executive pay in 23 countries shows that executives in the US receive a greater proportion of their pay from bonuses and incentives than from base salary. Another reason for high CEO compensation was the fact that a major portion of their compensation package consisted of stock options and stock grants. In some cases, nearly two-thirds of the CEO's pay assumed the form of stock options. Some companies offered options packages to compensate for low salary and risk associated with the company, especially in case of a start-up company. Stock options had emerged as one of the most important factors, which made the CEOs salaries in big companies in the US to swell to almost 458 times the

Letters - Assignment Example When I attempt to toast a bagel or any other type of food, the toasting units only become mildly hot. Rather than glowing red as they typically do, the toaster is unable to even moderately toast the thinnest slice of bread.

Emotional Effect Music Can Have on a Film Essay

Emotional Effect Music Can Have on a Film - Essay Example According to the essay "Emotional Effect Music Can Have on a Film" findings, music in the film can have the effect of convincing the audience to believe the actions or the mood portrayed by the character as opposed to simply accepting the scene and the overall mood. For example, when a ballad is played repeatedly every time an actor is onscreen, the audience will ultimately connect the mood of the music to the character (Tan et al139). An example of this is the haunting song by David Raskin which was used repeatedly in the film Laura which resulted in the film acquiring a deeper feel owing to the perceived depth of the score. Music is used to direct the sympathy or empathy of the audience towards the characters that the director wants to depict as good of evil respectively, as such, in a film, the soundtrack played when the villain is onscreen is likely to be eerie and designed to evoke apprehension tension or fear (Juslin and Sloboda 371). Nevertheless, when the protagonist is onscr een, the music played will be evocative of hope and in action scenes when the antagonist is winning cheerful hopeful music such as the â€Å"eye of the tiger† which is considered by many to be the anthem of motivation in modern film. Used effectively as a synesthesia, music can create mood in which an audience will be subtly manipulated into associating a certain piece of music with a given mood, from a Gestalt perspective, one may even argue that some of the emotional evocations are innate,. Films such as Phycho 1960 and the more recent horror series Saw, (2005) use a variety of musical devices such as pitch, tone and melodic line to create a classical conditioning that succeeds in making the audience nervous and even scared, which is the purpose of creating a horror film in the first place. When a file plays music from which an audience can make a direct connection to the based on the retrospective themes covered by the music, it has the distinct effect of bringing past emotional experiences into the current viewing

African American History Essay Example | Topics and Well Written Essays - 1250 words - 1

African American History - Essay Example The following study text will evaluate King’s role in the Civil Rights Movement with regards to his unique and effective strategies applied in acquiring overwhelming victory against white supremacy. Born in January 1929 as Michael Luther King, King grew up in religious environment and both his father and grandfather were pastors at the Ebenezer Baptist Church in Atlanta. In 1948, he earned a B.A. at the Morehouse College and proceeded to the Crozer Theological Seminary in 1951. In 1955, he earned a doctorate from the Boston University where he also happened to meet his wife Coretta Scott. After his graduation from Boston University, he began his pastoral role as at the Montgomery Avenue Baptist Church. This is where his journey into world history began. Rosa Sparks, a young black woman refused to give up her seat for a white person to sit in a bus and this had sparked controversy all over the United States around 1955. By chance, King’s Montgomery Church was chosen as the meeting venue to host one of the meetings to discuss the matter, and King happened to be there1. The meeting acted to recruit King into his call of advocating for the end to racial discrimination in the United States. Rosa Sparks was thrown into jail and King could not stomach the sense that she had been jailed for failing to give her seat to a white person. Following this, he planned his first public demonstration. In the same year, he mobilized the entire Montgomery [mainly African American] community to boycott the city’s transport service. He demanded equal rights for all. After an unending one year of boycott, a court ruling in Browder V. Gayle put an end to the discrimination on the public bus service and everyone was free to board the buses. This did not end, but sparked a new struggle aimed at eradicating racism all over the United States2. Martin Luther King Jr. was

Protection of vulnerable people (ADULT WITH DEMENTIA) Essay

Protection of vulnerable people (ADULT WITH DEMENTIA) - Essay Example Being a serious mental disability, adults suffering from dementia face many challenge in their routine life particularly learning disabilities. These adults are often abused at different intervals of life. This paper aims to highlight the abuses and challenges faced by adults with Dementia. Moreover, the will provide methods through which the vulnerability of these adults can be reduced. The paper will also discuss laws and policies that safeguards adults with dementia. Background One of the serious health problems faced by adults across the world, particularly the UK is Dementia. This is because of certain factors. One chief reason is that the aging of people in the UK is increasing. For this reason, adults that are diagnosed with Dementia in UK are increasing every year. The term ‘Dementia’ is originally a Latin word which means irrationality; ‘De’ means without and ‘mens’ means mind, thus it illustrates that without mind (Adams & Manthorpe, 2 003). Previously unimpaired people can also undergo dementia. It is a progressive brain dysfunction in which the person faces long term decline in his mental capabilities. The chief cognitive regions of the brain affected by Dementia include memory, attention, language and problem solving which makes it difficult for the person to perform various tasks. If these dysfunctions stays or are present for more than 6 months, then it is in positive support for the diagnosis of dementia (Hughes, et al., 2006). Dementia is a growing disease in the UK. Many adults are facing challenges to continue their routine life normally and are abused at different points because of this mental disorder. Moreover, adults diagnosed with dementia also face some financial challenges that do not allow them to treat their sickness, thus increasing the problems. The government of United Kingdom has set some laws and policies for patients with mental sickness. This is to ensure that those diagnosed with mental d ysfunctions are getting proper treatment and are able to continue their life. Moreover, adults who are diagnosed with dementia also face learning disability issues (Keady & Harris, 2013). Body Abuses / Challenges Faced by Adults with Dementia To name there are a number of abuses and challenges that are faced by adults with Dementia. These challenges vary from person to person. According to a report conducted by Kings’ College London and Alzheimer’s society stated that it is estimated that by 2025 as many as one million people will have dementia in UK. This is a serious issue which raises many other problems for the adults making them vulnerable towards life (Alzheimer's Society, 2013). People have not understood dementia completely, thus they are not able to offer this disease a comprehensive reaction. For this reason, dementia adds to the miseries of adults. Where on one hand these adults find it hard to cope-up with their daily tasks, the disease and other factors in a variety of ways often abuse them. It is already discussed above that adults with dementia face issues with memory; this illustrates that they have problems remembering their name, the day, week, and month; in short they are not able to recall anything properly. This can be explained with the help of few examples. Imagine, you wake up one morning and you are not able to recognize the person or his name that is lying next to you. This gets even worse when you look at your siblings and other family members and asks

Heredity, Genetics and Protein Synthesis Essay Example | Topics and Well Written Essays - 3500 words

Heredity, Genetics and Protein Synthesis - Essay Example In ancient times, people wondered how babies were born and why they share many characteristics of their parents. For long it was a mystery, until Gregor Mandel, an Austrian monk introduced some principles that formed the basis of modern genetics. He explained that these characteristics or heritable properties are transferred as units called genes. (Sharma 2005, p.2). With the development in science and availability of modern research techniques, it was soon confirmed that these genes are nucleotide sequence in a DNA molecule. This sequence is like an instruction manual of how characteristics will be developed in an individual. As Mandel had explained earlier, one characteristic or gene is inherited from each parent. But where are these genes located and how they are transferred from parents to offspring? This was the question that was soon answered following a year after Mandel’s death. It was initially proposed that genetic material is located in nucleus. Walter Sutton and Th eodore Boveri proposed in 1903, that genes are carried in special structures called chromosomes. (Sharma 2005, p.14). Genes are set of instruction carried by special molecules called Deoxyribonucleac Acid or DNA. It is this molecule that winds around histone proteins to form a chromosome. DNA has a unique structure that enables it to preserve and transfer genetic material. DNA is a double stranded, anti parallel helical structure with a deoxyribose sugar and a phosphate backbone. Each nucleotide has either a purine or pyramidine nitrogenous base attached to it. Guacine pairs with cytosine and thymine pairs with adenine on complementary strands. This variable sequence of base pair is actually the genetic code. A specific gene is present at fixed location on a chromosome called locus. There are 23 pairs of chromosome present in a somatic cell of a human being and each parent contributes one chromosome to form that pair. How these chromosomes are transferred from parents to offspring? The answer is simple; gametes of each parent contain 23 chromosomes and when two gametes fuse these chromosomes are added together in one cell called zygote. All the subsequent cells that are formed from zygote by the process of mitosis contain identical genetic material. So any somatic cell has a pair of same chromosome, one from mother and one from father. As mentioned earlier, genes are present at fixed locations on a chromosome. If there is a pair of chromosome it means there will be two sets of same gene, one from each parent present at the same loci. The base sequence of these two sets of genes may not be same and this variation in gene is called an allele. (Kail & Cavanaugh 2007, p.44). Now important question is which of these two genes will be expressed in the offspring? Remember that genetic makeup of an individual is called genotype and its physical expression is a phenotype. In most cases, both alleles are expressed to produce a phenotype. Sickle cell disease is caused by mutation in the beta haemoglobin gene. When this gene is expressed it forms an abnormal protein which causes alteration in the shape of red blood cell from biconcave disk to sickle shaped (Bloom, 1995). As part of previous discussion, this gene also has two alleles inherited from each parent. An individual with only one mutated gene will not get this disease because the other normal gene will also be expressed and compensate for abnormal gene. This is a very good example of how genes are key determinants of human characteristics. Not all sequences in a DNA represent a gene. All the genetic material in nucleus and in mitochondria together is called a genome. Only 1% f this genome is actually genes. Thousand of these genes guide species in growth and development of other characteristics. One gene

Physical Education and Academic Achievement in 10th grade Essay Example for Free

Physical Education and Academic Achievement in 10th grade Essay Physical education in high schools in the United States of America is the one branch of academic filed which is gaining fast attention on the side of the Government policy, the schools administration. More and more emphasis-shift is being observed toward orientation of the students and their parents with regard to the importance of physical education and its connection with real life, health, and, above all, with higher academic achievement. In schools, although all grades bear importance with relation to physical education and higher academic achievement and attendance rate, it is, however, the ninth and tenth-grades where there is a turning point for the students. Therefore, it is the time for the schools administration to pay more attention toward the planning and application of the physical education in these grades. â€Å"Physical activity is critical to the development and maintenance of good health. The goal of physical education is to develop physically educated individuals who have the knowledge, skills, and confidence to enjoy a lifetime of healthful physical activity† (aahperd. org) It is apt to say that the way their physical education is planned and implemented required different parameters. This is so because the demands of students are different. They need to be exposed to such physical activities which not only excite them but also create a sense of responsibility in them; the main focus of such activities should then be to prepare them for real-life situation and challenges.

It also focuses on the link between physical education and its advantages when it comes to higher attendance rate and so on. The paper also investigates the findings of some major studies conducted in the area of academic achievement and its hypothesized relationship with such other diverse areas as after-school pursuits, homework phenomena, types of activities in and out of school, cross gender and ethnicity issues. This is to give the reader a proper understanding of the major issues in the present debate of achievement in high school and particularly of the tenth-graders. Review of Literature Physical education is a â€Å"systematic instruction in sports, exercises, and hygiene given as part of a school or college program† (infoplease. com). Thus, there are certain goals to be met by implementing the physical education scenario. There have been considerable attempts in encircling the physical education curriculum in the United States of America. However, it is only recently that more and more emphasis is being laid on the importance of physical education and its link between higher academic achievement and proportionate significance of attendance rate. Since the year 1987, NASPE (the National Association for Sport and Physical Education) has been in constant pursuit in the updated information about the awareness in public of physical education in US education system. There are certain reservations that come to us in this regard. Three of them are mainly discussed in the present literature about physical education in the US educational system. These are: (1) There is no federal law, as yet, which says that physical education is to be provided to the students in the US education system; also there are not listed any incentives to offer physical education programs. 2) Although states may come up with some ground for the physical education policies, the state schools are free to work on their own in promoting, retaining, reducing the physical education portfolio in their own way. ) Another issue is that many states let go the responsibility for all content taught in schools to local school districts. (pe4life. com) The evidence is also found on other literature and net resources that plainly make it public that in the United States of America, physical education is not something prioritized. Even physical education in high school and elsewhere are â€Å"in sorry shape† and that the physical education â€Å"has been squeezed out of school by new curriculum requirements and other factors† (ducationworld. om). Apart from this, there is now word by such professionals as physicians who see that physical education is very necessary for a better future generation. More solid evidence comes form the Report to the President: Promoting Better Health for Young People through Physical Activity and Sports. In this report, Donna Shalala, Health and Human Services Secretary, and Richard Riley, Education Secretary, boldly wrote: â€Å"Our nation’s young people are, in large measure, inactive, unfit, and increasingly overweight. This report should stimulate action to make sure that daily physical activity for young people becomes the norm in our nation† (pe4life. com). Although we can see that today more and more attention is being paid to the physical education policy in US education system, there are grave critical areas that need to be addressed for a better physical education policy. For example there are trends of abating physical education time in schools because of pressure from academic side. This is very much a problem present in today’s education system. The simple fact is that more and more research findings are coming along with results that show that the old maxim â€Å"sound mind in a sound body† is aptly right. Thus it is now acknowledged that the students who are physically fit perform better on the academic side as well. In this connection we see that: â€Å"a 2002 California Department of Education study found a direct correlation between higher levels of physical fitness and higher academic test scores. According to Delaine Eastin, California State Superintendent of Public Instruction, We now have the proof weve been looking for: students achieve best when they are physically fit† (pe4life. com (b)). As such, a new educational approach is now being said to be coming up on the educational front of the US schools that is called ‘total mind, total body educational approach’. In addition to the above, U. S. Surgeon General Report states that â€Å"Nearly two out of three adult Americans, or 130 million of us, are overweight or obese†; as such The health problems related to our growing girths are well known – more heart diseases, diabetes and other weigh-related ailments that send 300,000 Americans to an early grave every year. In fact, if childhood obesity continues to grow at current levels, some health officials contend, this generation of youngsters may actually have a shorter lifespan than their parents – a first in history† (smc. edu). When the report gives this alerting call to the nation, it is of much relief that in the same report the U. S. surgeons also carve out some strategies to overcome the problem. Among these strategies, the most prominent place is give to the physical education for the youths in the high schools. However, this is also not wrong to state that with the advent of the recognition of physical education in high schools, specially in ninth- and tenth-grades, another debate has taken birth: Whether or not physical education grade be included in high school students’ GPA. This school of thought considers that inclusion of physical education grades in student’s GPA will boost up students’ morale and will encourage them to do better in the physical education class because â€Å"Physical education is truly a microcosm of life, and every lesson taught has the potential to translate into the real world and prepare students to become healthy, productive members of society† (elibrary. bigchalk. com). Whatever the arguments are, we can be certain that in today’s literature about physical activity and high schools, physical education is something that needs more and more space in schools policies so that a better tomorrow can be handed down to our future generation that is already getting more pressure from academic side. If we look at the schools curriculum regarding physical education of ninth- and tenth-grades, we find that there are no serious attempts at defining the education. For example, a school in US states only three basic goals for physical education for the ninth- and tenth-grades (benton. k12. wi. us). Another school very shortly gives only the names of the physical activities to be observed by the students (rockingham. k12. va. us). This kind of treatment is in abundance and needs serious attention on the part of the government and school administrations to bring solid measures for the improvement in this area. Physical Education and Academic Achievement in 10th-grade When it comes to physical education in high schools, we find that it is very important for people who are in grades ninth and tenth because â€Å"This is an age when students begin to impose self-judgement in terms of accepting their physical appearance and their willingness to involve themselves in positive physical activities† (teacherweb. com). According to the Physical Activity and Health (a report of the surgeon genera) there is deep linkage between physical education and academic achievement. Physical education makes it possible for a better and healthy start in life enabling students to go for challenges that are not touched upon by those who are not active through physical activity. Moreover, the report suggests that schools should create such programs that can offer students opportunities by which they can get into physical activity. At this stage, this becomes more important because that report informs that as people grow, they show more and more declination in goring for physical activity: â€Å"Physical activity declines dramatically with age during adolescence† (cdc. gov). Thus, there is stark need that students of ninth and tenth-grade must be made aware of the importance of physical education and their academic achievement. The physical education should also be given priority by the school administration so that a sound educational environment can be achieved for healthier and academically better grounds for the students of high schools. This has been found through the research that physical activities may enhance cognitive functioning of the brain. This, as a result, may explain the relationship found between the students’ involvement in physical activities and their academic success (nps. 12. va. us). There are three major findings in the literature that relate physical activity involvement and the cognitive functioning. These are: 1) There is a significantly â€Å"positive relationship between physical activity and cognitive functioning in children†; 2) â€Å"Results support possibility that participation in physical activity causes improvements in cognitive function†; 3) â€Å"Acute bouts of physical activity exert short-term positive benefits on the behavioural and cognitive functioning of youths†; ) It has also been found that â€Å"Being on a school sports team and having a positive achievement orientation were positively associated with physical activity levels† (holidaycalendar. dsr. wa). Therefore, from this very analysis it becomes pretty clear that in 10th grade (or roughly in high school), physical education plays a very important role as far as the phenomena of long, healthy life is concerned; as far as real-life active participation by the youth is concerned; and, above all, their academic achievement is concerned. However, looking at the picture more closely, we find that the present scenario in the United States of America, when it comes to physical education, academic success, link between physical education and academic success and real-life situation; there are certain challenges present to the Government. For example, â€Å"Nearly half of young people aged 12-21 are not vigorously active on a regular basis and physical activity declines dramatically with age during adolescence† (arlington. k12. va. us). And this has surely given the government a call of high alert because it is simply suggested that less physical activity on the side of the youth will give rise to ailments that will in return proportionately affect academic achievement of the students. Thus, today we can see that the United States of America is building more solid policies for coping up with the situation. In this very connection, a recent example is the President’s Challenge program, which purely focuses on bringing the people of the U.  S. to the physical activity grounds so that a healthier society for the future can be the possibility. This is â€Å"a program that encourages all Americans to make being active part of their everyday lives. No matter what your activity and fitness level, the Presidents Challenge can help motivate you to improve† (presidentschallenge. org). The Presidential Challenge program is all about remaining with an active lifestyle and the program specifically focuses on how to assess the citizens in this regard. This program also introduces some rewards for the participants of the program like PALA (Presidential Active Lifestyle Award (presidentschallenge. org). This simply gives us the idea that the government of the U. S. has come up with grave policies which focus on the physical fitness of the citizens for a better tomorrow and a healthy society. Physical Education and Academic Achievement Debate  There are different schools of thoughts within the research that circle around the relationship between academic achievement in students and such other phenomena as physical education, homework, social loafing, and so forth. A considerable area of research exists that especially takes into examination the students of eighth to tenth grade. For example the article After-school pursuits, ethnicity, and achievement for 8th- and 10th-grade students which is one of the remarkable piece showing the contribution of people like James B.  Schreiber , Elisha A. Chambers, Walberg, Paschal, Weinstein, Cooper, and so on. Thus the proponents of homework suggest that â€Å"Homework has been shown to have a positive relationship with† academic achievement. And that there is also a proportionate difference between the amount of time spent on homework (After-School Pursuits). However, the other side of the pole comes up with the argument that there is not total contribution that can be related to homework alone when looking into the matter of higher academic achievement. This school of though aptly analyzes the effects of physical education on academic achievement of the students. For example, a research review by Holland and Andre in the year 1987 brought into their examination the relationship, if any, between physical education or athletic participation and academic achievement in the students. Their findings brought some more elements of debate in the intellectual circle because they found that there were sex-related differences among students as far as physical education and academic achievement is concerned. They reported that the research demonstrated that male high school athletes received somewhat higher grade point averages (GPAs) than did nonathletes. However, when one considers standardized achievement or aptitude tests, boys whose only after-school activity was sports scored lower than national averages on the Standardized achievement Test. No significant differences in GPAs or standardized tests were observed between female athletes and nonathletes† (After-School Pursuits).

The development and evolution of Gregorian chant

The development and evolution of Gregorian chant For centuries, Gregorian chant was considered the official music of the Catholic Church. Naturally, this degree of importance placed on the genre gives it considerable significance, both religious and cultural. Its exact beginnings, however, are not absolutely known. Also, chant has changed over time due to it being based on practices of the Church, which have also changed over time due to decrees by various popes, agendas of monastic orders, and the influences of and intermingling of cultures, such as the Franks, Romans, and Byzantines. Although the name of Gregorian chant is derived from Pope Gregory I â€Å"The Great†, it has its roots much earlier in history, predating Christianity. In fact, Christian chant is believed to have been originally derived from Judaism, as there was a considerable amount of common ground between Jewish and early Christian liturgies (Werner 20). This is seen through writings of the early church which show that the early Christian church was heavily influenced by Hebrew worship (Barton). However, there is little information available from chants of early centuries compared to Gregorian chant and other chants of later centuries (Hiley 478). One reason for this is that musical notation for chants of this time did not exist, for at this time chants were an entirely oral rather than written tradition. Also contributing to this lack of information is that early Christians were persecuted, forcing private worship until the Edict of Milan of 313, which gave Christians the right of freed om of worship in Rome (484). Due to this freedom, Christianity could afford to become more formalized and organized, its music included. There is further ambiguity surrounding the specific origins of Gregorian chant in considering Pope Gregory himself. What Gregorys influence was on Gregorian chant is debatable, as there is limited evidence supporting that he either had a great deal of influence on the genre, such as directly composing chants, or virtually none (513). However, two pieces of evidence support a common theory of his involvement in the creation of Gregorian chant that was known throughout the Middle Ages, which are two books written by Pope Gregory. These two books, entitled Antiphonarium and Graduale Romanum, are compilations of already existing chants that Pope Gregory designated for specific parts of Catholic mass which supports the theory that his involvement was limited to such compilations (D‘Silva). An example of Gregorys ordering to use specific music in liturgy is him mandating that the Allelulia be used during mass for an entire year (Apel 41). Despite the lack of specific information concerning the beginnings of chant that would later evolve to become Gregorian chant, the origins of Gregorian chant as it was known throughout the Middle Ages are more clear, as music books, although they still were not musically notated, of the genre were created by the Franks at around the 9th century, making the genre easier to trace through history to that point (Hiley 514). Note that it was not until the 10th century that sources were created containing musical notation, namely being musically annotated Graduals and Antiphonals from the Codex 359 (Apel 52). Also, it was not until the 11th century that music was annotated in a way so that tunes could be read (53). In addition to these musical books, various manuscripts were written that outlined liturgical proceedings, allowing for further clarification of the specifics of Gregorian chant (53). The peoples who ruled the area that is roughly present-day France played a large role in forming Gregorian chant to what it is, from the Franks to the Carolingians (Hiley 512). This started under the rule of the Frank king Pepin, who lead the Franks to control much of Europe through military conquest, spreading the culture of chant to the Franks, and also causing reforms to Gregorian chant by the Franks and their successors (513). In addition to causing chant to be more widespread, the intervention of the Franks also caused Gregorian chant to evolve from further influences (513). Not only did the influence of the Franks allow the beginnings of Gregorian chant to be seen more easily, as was described previously, but their musical texts also show the original motives behind its development, the main motive being to help control how the liturgy was run by assigning specific chants to certain parts of the liturgy, as was done by Pope Gregory (515). In the case of the Franks (namely Pepin and also Charlemagne), the reasoning behind trying to control the specifics of the liturgy was so that it would become standardized since many members of the church were influenced by their own local traditions in structuring the liturgy, which Frank leadership was trying to suppress (Barbon). Of course, due to the amount of time between Pope Gregorys writings and the adoption of chant by the Frankish church (300 years), it can be safely assumed that the liturgical assignments of the Franks were different than those of Pope Gregory. More changes were made as well in Gregorian chant, including the style of singing, such as the combining of both Roman and Frankish singers, although eventually a return to a more Roman styled liturgy and type of singing occurred among the Franks (Hiley 517). Since writing texts for the chants was still not common practice and musical notation for them did not yet exist, it follows that the Franks had to learn Roman liturgy and chants by memory when this shift back to strictly Roman liturgy occurred. This also denotes that the number of chants that were used and popular were not too numerous at this point in time, as they could still be all memorized. Despite the shift back to a Roman style liturgy, over the years and into the 9th century to the start of the rule of the Carolingians, who succeeded the Franks, Gregorian chant continued to evolve as new musical elements were added to the genre by the Franks and more compositions were created (Hiley 517). Some of these changes were brought on by outside influences on Gregorian chant, such as by the Byzantines, who developed the eight mode system (529). The fact that the amount of compositions of Gregorian chant were increasing can be tied in with the development of written musical texts around this time period, causing Gregorian chant to shift away from a strictly oral tradition, for it would no longer be possible to memorize all of the chants necessary as their numbers grew. As the popularity of Gregorian chant grew, it underwent several more reforms and evolutions, mostly during the 12th and 13th centuries (Hiley 608). An example of such a reform was more specific notation being used in writing chant, which included specifying pitch, among other specific musical elements (608). Another reform was the tendency to drift away from previous melodies of the Middle Ages, creating a type of chant called â€Å"Neo-Gallican† chant (609). Many of these changes made to Gregorian chant were initiated by various orders, two major ones being the Cistercians, who believed in performing the liturgy as it was done originally, and the Dominicans, whose reforms, like the efforts of many before it, were aimed at standardizing the liturgy (612). Gregorian chant did not enjoy constant growth and popularity, however. After the 12th century, the popularity and growth of Gregorian chant started to wane, presumably due to a period of reduced popularity of the Catholic Church (DSilva). Also, around the 16th century the Catholic Church was threatened by Protestantism, which also played a part in decreasing the popularity of the church, thus affecting the popularity of traditional monastic liturgies and music (Hiley 615). Another such period of decadence for the church and for Gregorian chant was during the age of Enlightenment, as less emphasis was placed on the church and God and instead more on the individual and reason. As a result of this new ideology, the power and influence of the church began to decline. In addition to the general ideology of the time, another reason for the decline of the Church was the political struggle caused by the French Revolution, which caused a reform in the French church so that it no longer observed previous monastic traditions (Bergeron xii). Due to Gregorian chants close association with the church, its popularity began to decline as well (Barton). This causes yet another obstacle in acquiring information about Gregorian chant and thus makes it more difficult to interpret today as the knowledge of how to interpret various medieval musical notations was lost (Barton). A large factor of why Gregorian chant did not die out completely is the involvement of monks at the French monastery at Solesmes, and other such monasteries, who during the 19th century were commissioned by Pope St. Pius X to modernize Gregorian chant (DSilva). They achieved this by removing the strict association that Gregorian chant had with the church, secularizing it and adding a meditative, â€Å"trancelike appeal† (DSilva). In the end, Gregorian chant was changed to be more akin to classical Roman chant than the Gregorian chant of the Middle Ages. As a result, the chant that is known today as Gregorian chant is more similar to early plainchant rather than what was originally dubbed as â€Å"Gregorian chant† (DSilva). As a result of this change of the style of Gregorian chant, along with the declining power of the Catholic Church and thus the popularity of Gregorian chant, it is difficult to know what Gregorian chant of the Middle Ages exactly sounded like (Barton). Another factor that contributes to this is the lack of musical notation with text in the Middle Ages, and that some of the notation that does exist from the time period cannot be interpreted due to these periods of decrease in popularity. Overall, the fact that chant was originally a purely oral tradition that consisted of few enough chants that could be memorized, along with Gregorian chants affiliation with a religion that was originally persecuted and later declining in popularity, contributes to the murkiness of the origins of Gregorian chant. Also, the fact that Christianity underwent significant changes from the time of its conception to modern times results in equally significant changes occurring in the style of music that was so closely affiliated with its prominent church, even causing Gregorian chant to nearly die out on several occasions in history. However, despite the several bouts of decrease in popularity that Gregorian chant experienced, it is currently one of the oldest forms of music that is actively listened to today (DSilva). Also, the many changes that Gregorian chant underwent throughout history makes it very unique, as it cannot be entirely attributed to any specific event, person, or even nation or empire. Instead, as David Hiley states, â€Å"†¦Gregorian chant is neither of one specific time, nor wholly Roman, nor wholly anything else† (Hiley 513).
