Carpe Diem Essay - 659 Words

The Latin phrase carpe diem can be translated into English as seize the day. Seizing the day means making the most out of ones life. It is a theme that is commonly found in literature, most notably, poetry. Poetry, like most of literature, goes through periods of change. In the seventeenth century, poetry began to move away from humanism and began to explore the everyday mans thoughts and feelings. Robert Herrick and Andrew Marvell were two poets who wrote during this time of change. Their poems To the Virgins, To Make Much of Time and To His Coy Mistress, are examples of the use of the carpe diem theme in poetry. In To the Virgins, To Make Much of Time, the poet uses images to convey a feeling of urgency, that one†¦show more content†¦He states: Then be not coy, but use your time, And while ye may, go marry; For having lost but once your prime, You may forever tarry. (813) Herrick explicitly states for the young women to use their time wisely: to seize the day. In To His Coy Mistress, Andrew Marvell addresses his mistress on the topic of coyness. Marvell believes there is not enough time in life to be demure, he feels one must seize every opportunity he or she has when it appears. The poets images in the poem also relay a sense of urgency, that time is quickly passing. According to Jules Brody of ELH, Two elements in the stanza announce its connection with the carpe diem tradition: the fugitivity of Time (`winged chariot hurrying) and its invidious rapacity (`worms shall try, `turn to dust). (61) The narrator of the poem claims to hear/ Times winged chariot hurrying near (827). He fears that the time he and his mistress have on Earth is not long and they must, therefore, make the most out of everyday they have together. He further illustrates this point when he discusses death. The narrator states his mistress will turn to dust,/ And into ashes all my lust./ The graves a fine and private place,/ But none, I think, do there embrace ( 827). Once she has died, there will be no more opportunities for them to express their love for each other.

string(52) " believe that they can no longer do for themselves\." Forever 21: Dealing with America’s Fear of Aging and Death Abstract It is estimated by the Center for Disease Control and Prevention that there will be 71 million U. S. adults over the aged of 65 by 2030 (CDC, 2011, May 11). We will write a custom essay sample on Forever 21 or any similar topic only for you Order Now It can be certain, as was with their predecessors, that the geriatric journey for these adults will be filled with multiple anti-aging face creams and miracle hair growth products as they reluctantly cross over to the last stage of their lives. As shown not only through our media and social interactions’ growing old is not the popular choice. Ironically, the reality is that aging and dying is just as significant as our first breath. It is a journey made by everyone and everything though it is fought with a resistance that cannot be denied. The basis of this paper will discuss the preconceptions and barriers, whether psychological or societal, that is linked with aging, and steadfast approaches that can be used to cope with the aging process and the reality that death is eminent. Keywords: ageism, aging, death, coping, geriatric, fear, quality of life Forever 21: Dealing with America’s Fear of Aging and Death A study performed by the National Consumer’s League reported that approximately 90 million Americans purchase anti-aging products or have surgical procedures performed to ward off the visible signs of aging each year (Nelson, 2005). As the baby boomer generation moves into their senior years, they may not be prepared for the psychological challenges that their predecessors experienced before them (Daniel, 1994). As Todd Nelson describes in his article, Ageism: Prejudice Against Our Feared Future Self, the old are treated as â€Å"second-class citizens with nothing to offer society† (Nelson, 2005, p. 209). A research model concluded that older persons in the United States were perceived as â€Å"warm, but incompetent† (Nelson, 2005, p. 215). Research suggests that the stereotyping of the older population is much more severe than originally thought, making it necessary for further research to find ways to reduce the disdain towards aging (Nelson, 2005). The negative attitude associated with aging has not always been this way. Historically, older individuals were once revered, and admired as they were considered wise and experienced. They were the historians of the past, teaching the customs and values to the new, emerging generations (Nelson, 2005). The degeneration towards the old occurred by way of technology through the invention of the printing press which allowed duplication of stories in mass distribution, making the elder’s status less significant. Another factor was the industrial revolution as progress dictated where families lived. This new mobility requirement did not settle well with the less adaptive and older generation, breaking apart the traditional family structure in order to secure employment elsewhere. Growing companies needed strength and adaptability during that time so the younger generation excelled professionally whereas experienced, older applicants were less valued. The advancements in medicine also extended a person’s life expectancy, prolonging the caregiver’s responsibility to its elder (Nelson, 2005). In Todd Nelson’s article, Ageism: Prejudice against Our Feared Future self, he discusses the social prejudices associated with aging, and the subtle ways those prejudices are conveyed. His primary focus is our aging population of baby boomers, and how they will be affected by being stereotyped in ways that are patronizing and degrading (Nelson, 2005). In an effort to thwart such negative attitudes, Jere Daniel, the author of Learning to Love Growing Old, describes a â€Å"vanguard† movement that is committed to changing the way aging is perceived. These individuals have evoked the term, â€Å"conscious aging† which promotes awareness and acceptance of the aging process as we move through each stage of life. The supporters of this movement confer that aging is not a curable disease, and it cannot be solved by spending billions of dollars on preventing its process or its end (Daniel, 1994). Another supporter of changing the way aging is conveyed is author, Margaret Cruiksbank, of the book, Learning to be Old. In her book she is a proponent of changing the way the aging process is described. Her position is that the underlying meaning of popular terms to describe aging weakens its value. She denotes that the term â€Å"successful aging† is a false phrase for the elderly as it â€Å"masks both the wish to continue mid-life indefinitely and the white, Middle-class, Western values of researchers, causing them to emphasize productivity, effectiveness and independence† (Cruiksbank, 2009, p. 2). She also concludes that the term â€Å"productive† aging symbolizes â€Å"economic usefulness and social conformity† (Cruiksbank, 2009, p. 2), especially for the female gender. More importantly, these terms can be used to measure. This ability to measure is subjective to the questioner and an individual’s self-worth. She suggests the term â€Å"aging comfortably† as it signifies easiness, and a â€Å"faint hint† of pleasurable self-indulgence which may not have been possible in younger years (Cruiksbank, 2009, p. 3). There has been decades of research examining what it referred to as â€Å"automatic categorization† (Nelson, 2005. p. 207). Researchers describe this as an essential trait in humans that is a primal response to physical characteristics, such as race, gender, and age, that automatically prompts emotional responses and prejudices. This type of categorization sets the foundation for stereotyping (Nelson, 2005). The aging community is faced with an array of negative stereotypes that affects their independence as well as their self-perception. Many times the negativity is hidden, almost overlooked as it in an unconscious gesture unbeknownst to either participant. Nelson discusses the use of patronizing language as a form of negative socialization. He states that researchers define its usage as â€Å"overaccomodation and baby talk† (Nelson, 2005, p. 209). This type of language is based on the stereotype that individuals suffer from hearing loss to a limited or degenerate intellect as a result of growing old (Nelson, 2005). Another form of stereotyping that has a debilitating effect on the aging adult’s self-esteem is a term called â€Å"infantilization† (Nelson, 2005, p. 210). This is described as a process that occurs over time as the aging adult relinquishes their independence, eventually leaving them to believe that they can no longer do for themselves. You read "Forever 21" in category "Essay examples" The aging adult is victim in believing that they are â€Å"old†, and subsequently begins to assume behaviorisms that depict old age such as moving and thinking more slowly. Researchers have found that this is prevalent in elders that have been over accommodated. The end result is that it not only affects the elder person but burdens their caretaker as well (Nelson, 2005). Another prejudice that is common is segregation of the old (Cruiksbank, 2009). Cruiksbank notes that even people over sixty five have a disdain for their peers, saying â€Å"they do not want to be around all those people† which may be their way of unconsciously avoiding their own mortality (Cruiksbank, 2009, p. 10). She states that distancing themselves may be a way they preserve their autonomy. Cruiksbank sees this as a form of denial, and also counterproductive as she eels solidarity needs to be exemplified by the old especially in this time of their lives. Gereontological research has also found other common patterns among the elderly and their peers. In another attempt to demonstrate independence, the elderly tend to generalize geriatric health issues. They segregate themselves by expressing how fortunate they are not to be suffering the same doomed fate (Cruiksb ank, 2009). All forms of media reinforce negative stereotypes associated with aging (Daniel, 1994). By as early as six years old, negative stereotypes have already formed about aging. These stereotypes continue throughout our lives, and are subconsciously accepted without question. Daniel concludes that society has no role models that favor growing old. A nursing home ad with a dialogue that emulates the aging parent as a problem or burden further acerbates the stigma. Culture and media are designed to postpone the evitable as it is geared towards staying young, and delivers that message from fashion to health (Daniel, 1994). The result of these stereotypes is that as we age, impending doom invades the individual’s thoughts. In an effort to conform to culture’s idea of individualism, the aging population perpetually seeks an elusive youth, thereby denying their mind and bodies the right to age (Daniel, 1994). It is not surprising then as the body begins to breakdown, that the aging person feels embarrassed and insignificant (Cruikshank, 2009). There is an ongoing movement to re-adjust society’s perception of what it means to age (Daniel, 1994). In an effort to shift the mindset of America’s aging, non-institutionalized studies have been done in American communities to determine the intellectual and cognitive effects of their aging population. The results concluded that â€Å"physical and mental decline is not evitable† Daniel, 1994). As the aging population grasps at their â€Å"desire to have meaning† in their lives, more attention needs to be focused on the positive influences that can enhance their daily existence. These influences include a positive attitude along with making healthy choices for themselves such as food, physical activity and recreation (Kerschner and Pegues, 1998). One way to improve the aging process is to be proactive in developing a healthy lifestyle that includes good eating habits and physical activity. Research has concluded that the mind is a powerful tool in creating reality so protecting one’s health can be a precept to a fighting off future ailments (Kerschner and Pegues, 1998). The choice to give back to the community creates a meaningful and positive response in many ways. The benefit of socially connecting in a structured atmosphere lends opportunity to share not only wisdom but to develop new relationships that otherwise would not have occurred (Kerschner and Pegues, 1998). Studies have concluded that people who remain active have a clearer sense of who they are and what value they hold in society as well as their community (Kerschner and Pegues, 1998). For every beginning, there must be an end. There is term called vertical axis which describes the mind-body experience when an infant first enters the world. It is believed that prior to a person’s birth, the mind and body are not aware of each other but as soon as they arrive, both are encapsulated by â€Å"sensation and emotion† as the two entities meet for the first time (Carvalho, 2008, p. 4). With the help of a mother’s touch, their union becomes a â€Å"seamless ensemble† (Carvalho, 2008, p. 4). The two live together, as one, for many years. It is not until the last stage of life, do they find themselves encapsulated by â€Å"sensation and emotion† again as now they have grown apart, separated as the aging body or mind is no longer able to oblige the other. They spend the rest of their days laboring until they can agree to leave together, in death. Fear of aging can ignite or dim the remainder of a person’s life. There is an array of products, books, and doctors promising new ways to reinvent the old self. In America, we are driven by the desire to stay young and because of this truth; the aging person experiences certain prejudices. Though, despite the adversity, aging can be a catalyst to many wonderful and positive experiences that could only happen because one is old. One outdated novelty, wisdom, is just waiting to be reinvented by today’s aging population, and it would nice to see it be born again. * * * * * * * References Center for Disease Control and Prevention.

Steinway was founded 1853 in Manhattan in New York City by German immigrant Heinrich Engelhard Steinweg (later Henry E. Steinway). The companys growth led to the opening of a factory and company town in what is now the Astoria section of Queens in New York City and a factory in Hamburg, Germany. Steinway is a prominent piano company,known for making pianos of high quality and for its influential inventions within the area of piano development. The company holds a royal warrant by appointment to Queen Elizabeth II. Steinway pianos have been recognized with numerous awards. One of the first official recognitions was a gold medal won in 1855 at the American Institute Fair at the New York Crystal Palace just two years after the companys foundation. In 1855–62 Steinway pianos received 35 gold medals. Several awards and recognitions have followed, including 3 medals at the 1867 Exposition Universelle in Paris. Steinway has been granted 126 patents in piano making; the first patent was achieved in 1857. Most of the patents have expired. Other than the expensive Steinway amp; Sons piano brand, Steinway markets two less expensive brands: Boston for the mid-level market and Essex for the entry-level market. The Boston and Essex pianos are made using low-cost components and labor and are produced in Asia by other piano manufacturers. And now, Steinway is dedicated to the ideal of making the finest pianos in the world. The result is instruments renowned for their unsurpassed quality. Pianos with such superior sound and responsive touch that they enchant the most demanding pianists. 2, Stradivari violin, made in Antonio Stradivari Website: http://www. gabrielenatali. it History: Antonio Stradivari (1644 – 18 December 1737) was an Italian luthier and a crafter of string instruments such as violins, cellos, guitars, violas, and harps. Stradivari is generally considered the most significant and greatest artisan in this field. The Latinized form of his surname, Stradivarius, as well as the colloquial, Strad, is often used to refer to his instruments. It is estimated that he made 1,000 to 1,100 instruments and that around 650 of these instruments have survived including 450 to 512 violins. Stradivaris instruments are regarded as amongst the finest bowed stringed instruments ever created, are highly prized, and are still played by professionals today. Only one other maker, Giuseppe Guarneri del Gesu, commands a similar respect among violinists. However, neither blind listening tests nor acoustic analysis have ever demonstrated that Stradivarius instruments are better than other high-quality instruments or even reliably distinguishable from them. Fashions in music, as in other things, have changed over the centuries, and the supremacy of Stradivaris and Guarneris instruments is accepted only today. In the past, instruments by Nicolo Amati and Jacob Stainer were preferred for their subtle sweetness of tone. While the usual label for a Stradivarius instrument, whether genuine or false, uses the traditional Latin inscription, after the McKinley Tariff Act of 1890, copies were also inscribed with the country of origin. Since thousands of instruments are based on Stradivaris models and bear the same name as his models, many unwary people are deceived into purchasing forged Stradivarius instruments, which can be avoided by having an instrument authenticated. Many violinists and cellists use Stradivari instruments in their work. Yo-Yo Ma currently uses the Davidov Stradivarius,Julian Lloyd Webber employs the Barjansky Stradivarius. Famous Performers: This one is quite self-evident. You are not restricted to any particular period or style. For example, if you favorite instrument is guitar, you can choose Eric Clapton and John Williams. Famous Piano Performer: Lang Lang Website: http://www. langlang. com. cn In this website,I got that Lang Lang is a Chinese concert pianist, I from China too! LOL! And currently residing in New York, who has performed with leading orchestras in Europe, the United States and his native China. He is increasingly well known around the world for his concert performances, television appearances, albums and soundtracks. Lang has done much to encourage children and young musicians to take an interest in classical music, especially through the international foundation he launched in New York in 2008. He is really a great person! I heard that he had play the piano at 5am,he also said when he was a boy, I didnt spend so much time with her, so now I really like her with me. My mum stayed at home for years, working, so now its time for her to see the world. I was touched! So I like LangLangs website,like piano than before! Famous Violinist Performer: Yehudi Menuhin Wensite: http://www. menuhin. org From this website,I known that Yehudi Menuhin was an American violinist and conductor who spent most of his performing career in the United Kingdom. He is often considered to be one of the greatest violinists of the 20th century. Also,Yehudi Menuhin was born in New York City, United States, to Jewish parents from what is now Belarus. His sisters were the concert pianist and human rights worker Hephzibah Menuhin and the pianist, painter, and poet Yaltah Menuhin. Through his father Moshe Menuhin, a former rabbinical student and anti-Zionist writer, Menuhin was descended from a distinguished rabbinical dynasty. Menuhin began violin instruction at age four under violinist Sigmund Anker; his parents had wanted Louis Persinger to be his teacher, but Persinger refused. In 1929 he played in Berlin, under Bruno Walters baton, three concerti by Bach, Brahms and Beethoven. In 1932 e recorded Edward Elgars Violin Concerto in B minor for HMV in London, with the composer himself conducting, and between 1934 and 1936 he made the first integral recording of Johann Sebastian Bachs Sonatas and Partitas for Solo Violin. So he is my fav Violinist Performer! Famous composers: Another self-evident one. Again, you are not restricted to any particular period or style. One example from the class is the Leonard Bernstein site at the Libra ry of Congress. Did Bernstein, for example, write any pieces for your favorite instrument? Famous Piano Composers: Wolfgang Amadeus Mozart Website: http://www. classicfm. com/composers/mozart/music/ From this website, I learned Wolfgang Amadeus Mozart was not only one of the greatest composers of the Classical period, but one of the greatest of all time. Surprisingly, he is not identified with radical formal or harmonic innovations, or with the profound kind of symbolism heard in some of Bachs works. Mozarts best music has a natural flow and irresistible charm, and can express humor, joy or sorrow with both conviction and mastery. His operas, especially his later efforts, are brilliant examples of high art, as are many of his piano concertos and later symphonies. Even his lesser compositions and juvenile works feature much attractive and often masterful music. Mozart was the last of seven children, of whom five did not survive early childhood. By the age of three he was playing the clavichord, and at four he began writing short compositions. Young Wolfgang gave his first public performance at the age of five at Salzburg University, and in January, 1762, he performed on harpsichord for the Elector of Bavaria. There are many astonishing accounts of the young Mozarts precocity and genius. At the age of seven, for instance, he picked up a violin at a musical gathering and sight-read the second part of a work with complete accuracy, despite his never having had a violin lesson. In the years 1763 1766, Mozart, along with his father Leopold, a composer and musician, and sister Nannerl, also a musically talented child, toured London, Paris, and other parts of Europe, giving many successful concerts and performing before royalty. The Mozart family returned to Salzburg in November 1766. The following year young Wolfgang composed his first opera, Apollo et Hyacinthus. Keyboard concertos and other major works were also coming from his pen now. In 1769, Mozart was appointed Konzertmeister at the Salzburg Court by the Archbishop. Beginning that same year, the Mozarts made three tours of Italy, where the young composer studied Italian opera and produced two successful efforts, Mitridate and Lucio Silla. In 1773, Mozart was back in Austria, where he spent most of the next few years composing. He wrote all his violin concertos between 1774 and 1777, as well as Masses, symphonies, and chamber works. In 1780, Mozart wrote his opera Idomeneo, which became a sensation in Munich. After a conflict with the Archbishop, Mozart left his Konzertmeister post and settled in Vienna. He received a number of commissions now and took on a well-paying but unimportant Court post. In 1782 Mozart married Constanze Weber and took her to Salzburg the following year to introduce her to his family. 1782 was also the year that saw his opera Die Entfuhrung aus dem Serail staged with great success. In 1784, Mozart joined the Freemasons, apparently embracing the teachings of that group. He would later write music for certain Masonic lodges. In the early- and mid-1780s, Mozart composed many sonatas and quartets, and often appeared as soloist in the fifteen piano concertos he wrote during this period. Many of his commissions were for operas now, and Mozart met them with a string of masterpieces. Le nozze di Figaro came 1786, Don Giovanni in 1787, Cosi fan tutte in 1790 and Die Zauberflote in 1791. Mozart made a number of trips in his last years, and while his health had been fragile in previous times, he displayed no serious condition or illness until he developed a fever of unknown origin near the end of 1791.

His two counselors are President Dallin H. Oaks, first counselor and president of the Quorum of the Twelve Apostles, and President Henry B. Eyring, second counselor. The rest of the members of the Quorum of the Twelve Apostles were also in attendance, including newly announced acting quorum President M. Russell Ballard, as well as other senior leaders. President Nelson, succeed s President Thomas S. Monson, who died January 2, 2018." I know his love of the people; I know of his wisdom," said President Oaks, who has served with President Nelson for nearly 34 years. "I am thrilled to participate in the leadership of this worldwide Church." The Church has more than 16 million members in nearly 190 countries around the world. President Nelson has traveled to 133 countries and speaks multiple languages. "For me it is a special joy to be at the side of these great men," said President Eyring, who served as first counselor in President Monson's administration. "We live in the most vibrant era in the history of the world," President Nelson told the reporters. "I wake up every morning and am excited for the adventures of the day. And I hope you feel that same cheerfulness for the gift of life . " The news conference was shared in 29 languages. Local media, as well as in us and international reporters, asked the First Presidency questions during the event. When asked by a reporter about the diversity of the leadership of the Church, President Nelson said, "Wherever we go, the leadership of the Church is from the local communities, and those are the real leaders." President Nelson, who has nine daughters and one son, answer to a reporter's question about women in the Church. "I have a special place in my heart about the women," he said. "We have women on our councils, we have women administering ordinances in the temple, we have women presidents of the auxiliaries and their counselors. We depend on their voices." "I think no greater influence exists in the kingdom than the women of the Church," added President Eyring. The leaders talked about the strength of the youth in the Church, despite media reports that many are leaving organized religion. "There's a power coming in this millennial generation' that is in fact remarkable and greater faith than I can remember," stressed President Eyring. "I thought I had faith when I was 18, but I'm seeing some 18-year-olds now and some 20-year-olds and 25 -year-old that have a rock-solid faith, a love of the Lord and are willing to do everything they can to serve Him and each other, other people. I think it's the best of times of the millennials." President Oaks talked about the clarity of the Church. "If we weren't interested in transparency, we wouldn't be publishing all the papers of the Prophet Joseph Smith and the documents that came out of the founding of this restored Church." "I declare my devotion to God our Eternal Father and to His Son, Jesus Christ. I know and love Them and pledge to serve Them and you with every remaining breath of my life," concluded President Nelson.

PhD Thesis

PhD Thesis PhD Thesis PhD ThesisPhD thesis is a report on the research conducted. This report should describe what was already known about the problem under consideration previously, what you did to solve this problem, what you think the results obtained during research may mean, and how the further progress in the research area can be made. Do not forget to review free article on thesis format, research paper thesis writing as well as read great guide on writing a thesis .To write PhD thesis successfully, students should keep in mind that thesis writing differs much from undergraduate writing where they are expected to simply answer an assignment. What is more, in undergraduate assignments the reader usually knows what the answer is supposed to be. If it concerns PhD thesis writing, the reader does not know what your answer to the question will be. You have to present your ideas and backup them with solid evidence. Evidently, your examiners will read your PhD thesis. These people are experts in the ge neral field of your topic. However, nobody but you is the world expert of a particular issue regarding your research topic. That is why when writing PhD thesis, keep in mind that you should make the topic clearer to the reader. The style of PhD thesisIt is obvious that your text should be clear, and your grammar should be perfect. Still, scientific writing requires more than that. Keep your sentences short and simple. Of course, sometimes you will need to use complicated sentences because an idea may be much complicated. Some lengthy technical words will also be necessary especially in case you are writing PhD thesis on biochemistry or alike. Still, you should always remember that non-native speakers may also be readers of your PhD thesis. That is why you should care about simplicity of your sentences. PresentationSometimes students spend too much time on figures, diagrams, tables, etc. However, this time might be spent on examining arguments, making the explanations clearer, checki ng the mistakes, etc. The reason of course is that it is much easier to draw something than to think how to improve your writing. Actually, a neat diagram may be drawn even by a hand faster and scanned to include it into PhD thesis. If you use photographs for your PhD thesis, think about an appropriate compression format, such as .jpg (for photos) or .gif (for diagrams). Further, you will be able to save space or speed by reducing the number of colors. This is only the smallest part of the information you should know about PhD thesis. Still, nobody but your supervisor will better explain you how to prepare it successfully.

Timber Cruising Equipment and How to Use It

Timber Cruising Equipment and How to Use It Ed. Note: The first essential step toward selling timber or timberland is an inventory. It is a necessary step which enables the seller to set a realistic price on both the wood and the land. The inventory and methods used to determine volumes are also used between sales to make silvicultural and management decisions. Here is the equipment you need, the cruising procedure  and how to calculate the cruise. This report is based on an article written by Ron Wenrich. Ron is a sawmill consultant and has extensive knowledge on how to inventory your forest using the point sampling method. It is written in three parts, this being the first part, and all links included were chosen by the editor. You could measure every tree and do a 100 percent appraisal, but this is very time consuming and costly to do on large forests. But another way is to use a sampling system. A proven system, called point sampling, is used regularly by foresters and can be used by timber owners as well. We will discuss point sampling and the equipment you need here. Point Sampling Point sampling is a method of determining the frequency of occurrence of trees throughout the stand using a fixed point. These points can either be random or systematic. What you will be measuring is the basal area of the trees occurring at that point or plot center. Basal area is the area of the cross-section of tree stems near their base, generally at breast height, and including bark measured over 1 ac. or ha. of land. This basal area (BA) is then used to calculate the volume of a tree. Basal area increases as stand size and site quality increases. Gauges Some sort of gauge is needed to determine which trees are counted and which trees are not. An angle gauge - either prism (the prism is a wedge-shaped piece of glass that will deflect the image when viewed), string, or stick gauge can be used. Several types of angle gauges can be purchased from any forestry supply company. A stick gauge can be constructed by putting a target on the end of a stick and by keeping a 1:33 ratio. A 1-inch site would be put on the end of a 33-inch stick. You then eyeball each target tree with this gauge to find out if it should be included in the sample (more on this in a minute). It has been suggested that a dime can be used as an angle gauge. As long as a 1:33 ratio is maintained, anything can be used. For a dime, the distance held from your eye would be about 23 inches. A quarter would be held 33 inches away. An alternative to buying an angle gauge would be to build one. Build an Angle Gauge Take a 1-inch piece of sturdy material - plastic, metal, etc.- and drill a small hole to attach a string. Kite string will work well, knotting the string at 33 inches from the gauge and attaching it to the sighting device. Now, when using, simply put the knot between the teeth and sight your gauge with the string completely stretched. An alternative is to put a 1-inch notch in the material which creates a kind of sight. Before taking to the woods with one of these, youll need to know how to use one. Using Your Gauge Trees are counted at a point. This point can be random when just checking stocking at a certain point, or they can be located on a grid to get data for volume or other factors. Trees will either be counted or not counted. Counted trees will appear larger than the gauge. Trees appearing smaller than the gauge are not counted. Some trees will be borderline, and distance should be measured from the plot center if accuracy is desired. For most purposes, counting every other tree will yield effective results. It is also necessary to keep the gauge parallel to the tree. If a tree is leaning towards or away from the plot, the gauge should be moved accordingly. Prism Angle Gauges A prism (most foresters use this type gauge) will deflect the image of the tree that is being observed. Trees that are deflected off the main bole are not counted, while those that fall within the main bole are counted. The difference between the prism and the other angle gauges is that the user keeps the prism as the plot center while other gauges use the eye as the plot center. Prism angle gauges come in a number of sizes, known as factors or Basal Area Factors (BAF). For most purposes, a BAF of 10 is used. At your point you simply make a circle counting the trees that fall into your plot. Multiply by 10 and you have the basal area per acre at your plot. You will also notice that larger trees that are further away will be counted, while smaller trees will not. When computing number of trees, larger counted trees represent fewer trees than smaller counted trees.

Performance of the UK auto- and motor industry Literature review

Performance of the UK auto- and motor industry - Literature review Example Because of this superior level of internet sponsored network connectivity, the world has become a highly connected one single global entity. It is highly interesting to mention that the level of dependency that exists in between the organizations and business forums of various countries and markets is widely varying and largely diversifying in nature. As of the recent times, the advanced markets located in the well developed economies are facing factors of low demand because of the influence of a wide range of macroeconomic factors like the slow growth in the economy and fall in purchasing power of the consumers. It has become a common and normal trends for the companies and organizations located in the regions of slower growth to look forward to the markets of emerging economies like Africa, china, Russia, Brazil and India so as to secure their growth lines of the future (IMF Research Dept, 2012, p. 7) . The UK motor segment forms a very crucial and critical part of the entire motor industry of the European region. The factors like product manufacturing, combined participation and sharing of manufacturing policy by the auto manufacturers as well as the multiple markets served in a combined basis by the entire European automobile sector makes the contribution of the UK motor industry very important. It also has to be taken into account that the production of the automobile sectors in the UK region contributes in a positive manner in the economy and society of the nation (Johnson, 2002, p. 164). UK auto industry: sector overview It is highly relevant to mention that the most of the nations of the European region is facing extended periods of macro level economic challenges in regards to the troubles of the Euro zone. Since the UK motor industry shares a high degree of contribution based dependence with the entire European motor industry, it is very natural that the potential influence of the regions’ macroeconomic challenges is bound to cast a shadow on t he prospects of the UK automobile sector. As of October 2012, various reports on the automobile sector of the UK region hinted to the fact that around 1400 workers of the motor sector is about to lose their jobs as a result of cuts that are supposed to be initiated by the motor manufacturing giant Ford in its plant locations of Southampton and Dagenham. Further insights revealed that the job cuts in the motor sector is an outcome of Euro zone powered effect which comprised of uncertainty in the business environment as well as erosion in demand. It was also realized that Ford has focused on consolidating its manufacturing operations in the European region on the strategic grounds, while trying their best to absorb the case of depreciating demand of finished products from the European region. Talking on the lines of impacts and threats faced by the automobile sector of UK, it has to be said that the automobile sector faces serious issues on the lines of rising cost of manufacturing in the UK region as well as highly

Errors of metabolism (newborn screening) Essay Example | Topics and Well Written Essays - 1000 words

Errors of metabolism (newborn screening) - Essay Example (CPSP, n.d.) (Rinaldo, 1988) Various findings also suggets that this disease is genetically inherited via autosomal recessive pattern. Going deep into the molecular mechanisms of this enzyme’s expression, it was found that MCAD enzyme is expressed by ACADM(alias MCAD) gene located on chromosome 1p31. Due to a point mutation at position 985 on the gene, results is swapping of an adenine by a guanine, that results in replacement of a lysine by a glutamate residue in the protein leading to onset of disease. (Grosse, 2006; Wang SS, 1999; Matsubura, 1990). Around 80% of European individuals have at least two copies of this mutation. (Wang SS, 1999). Considering high mortality rate of 20 to 25% in undiagnosed cases, this disorder was included in the list of newborn screening programmes. (Wilson, 1999) Variation in Symptoms and Prognosis The deficiency of this enzyme is characterised by symptoms such as hypoketotic hypoglycaemia, vomiting (Egidio RJ, 1989) and hypotonia progressing t o coma. (BPSU, 2006). Other symptoms include seizures, coma, residual neurological deficits. No symptoms are exhibited at birth, except for the case when newbron screening is conducted. The symptoms show up any time between teh age of three to twenty-months; in some cases, it may show up much later. Once it is successfully diagnosed, prognosis becomes much effective by administering the patient with adequate treatment regimes (Matern, 2013). Diagnosis Prenatal-testing: Prenatal testing includes molecular genetic testing that helps in early diagnosis of the disease and thus enable the parents to be mentally aware and cautious of their child’s health. The first test includes the testing of analyses that include plasma acylcarnitines, urine organic acids and urine acylglycines. Biochemical diagnoses include the measurement of fatty acid ?-oxidation in fibroblasts as well as measurement of MCAD enzyme activity in fibroblasts and other tissues (Leydiker, 2011). Molecular Genetic t esting comprises of two methods that include Targetted Mutation Analysis and Sequence Analysis. Targetted mutation analysis a.k.a Allele specific mutation analysis involves the testing of the mutations p.Lys304Glu (985A>G) and p.Tyr42His (199C>T). Sequence analysis involves the testing of sequence variants may also include other mutations such as splice site mutations, non-sense and mis-sense mutations as well as small deletions/ insertions. This method does not target mutations identified by Targetted mutation analysis. Newborn- Screening: Newborn Screening differs from Pre-natal testing such that pre-natal testing is carried out during pregnancy and before the child’s birth, whereas the former involves the testing of the child’s health condition within first few days of birth (Matern, 2013). Tandem mass spectrometry was developed by Millington et al, for analysis of acylcarnitines in blood collected from umbilical cord as well as neonatal blood. This method proved to efficient diagnostic tool to diagnose MCAD deficiency. The simplicity and speed of the method enabled its use in everyday neonatal screening of infants (Millington, 1990; Kennedy, 2010) This tool has been widely used for screening of MCAD and has proved to be a robust, efficient tool. Newborns who are MCAD deficient have higher octanoylcarnitine levels than normal individuals; this forms an effective screening test, and has helped to decrease mortality and

The Impact Of Social Policies On Wellness Essay Example for Free

The Impact Of Social Policies On Wellness Essay The continual interdependence of states in global economic relations has necessitated debates on environmental, health and social related issues, making adoption and executions of policies the remedy for the various shortcomings in various sectors. Since policies are at the core of addressing major issues, the efficiency of health policies are affected by poverty, level of education and socio-economic status. (Leigh 2004:1-2) The impact of global policies on health, nonetheless has improved the quality of life, as more awareness is been mounted, the Health Impact Assessment (HIA) stands as a tool for measuring the impact of global and public policies on health. This cuts across environment, health, gender issues, and the continual relevance of policies has been seen in the EU’s adoption of policies to protect the environment and health. (Samuel Kefee 2007: 1-4) The role of governments stemming from the Federal governments still depends on adoption and execution of policies, the other tiers of government should work alongside the policies and ensure efficiency of services. The impact of Medicaid and other non-governmental organisations shows the role of networking and cooperation towards achieving efficiency and service delivery. The impact of health issues on welfare has refocused the direction of policies towards the health and environmental sectors. More funding needs to be directed at the Medicare services. The arguments of state welfarism and health have resulted in arguments of the best way to manage the welfare of citizens. The role of public or social policy in addressing the health, environmental and other issues is however crucial, the recent trend of paediatric obesity is associated with the United States Culture of consumption of energy dense foods and less exercise. ( Krishnamoorthy, etal 2006: 1-5) A need to turn around the whole situation requires effective policies and execution.

Civil war :: essays research papers fc

THE CAUSE Americans have always been independent group of people. We just don’t like being told what to do. This is true now as it was in the past, or will be in the future. It all started in the early colonial era (1700) when we really felt ourselves as â€Å"Americans†. Before that in the 1600’s we were just settlers in the new America. In the 1700’s we fought with the British to stop the union of France and Spain. We started our own newspaper, the Pennsylvania Gazett published by Benjamin Franklin. We opened the first American public library, the first hospital. We started the postal service with Benjamin Franklin as Postmaster General. All was not perfect in the colonies. The English Parliament started raising the taxes on imported items such as sugar, coffee, textiles and wines. We started raising the issue of taxation without representation. The English Parliament went as far as to introduce the Quartering Act, requiring colonists to house British troops and supply them with food. On April 19, 1775 an unordered shot begins the American Revolution. If the question at hand is what were the events that lead to the secession of South Carolina? Why did I spend two paragraphs on the American Revolution? Because I feel it is important to remind us of what kind of people we Americans are. How we will stand up for ourselves. I will not say we will fight for what is right, one cannot say slavery was right, or every fight we got ourselves into was right, but South Carolina and most of the south felt it was their right to own slaves. After all they had slaves in early colonial America when in 1619 a Dutch ship brought twenty Africans for sale as indentured servants thus marking the beginning of slavery in America. In 1793 Eli Whitney invented the cotton gin and more slave labor was needed to keep up with the vast amount of cotton that could now be produced. Less than forty years latter a growing anti-slavery movement was gaining recognition in the north. Harriet Beecher Stowe’s novel â€Å"Uncle Tom’s Cabin† helped spread the anti-slavery message. Everyday Americans who probably wouldn’t have given the anti-slavery movement much thought were now motivated by this book. The south had growing concerns that the anti-slavery movement was growing and could abolish slavery. After all this was a way of life for the south.

The Evolution of Total Quality Management

Until the industrial revolution in the mid 18th century, most goods were custom made. Industrialisation brought about a fundamental shift from cottage industry production to large scale manufacturing. Simultaneously, industrial activity underwent extensive mechanisation. As explained by Ho, ‘craftsmen were diminishing and being replaced by mass production and repetitive work practices.’ The aim with the new industrial era was to produce large numbers of the same product which required processes to be put in place to control quality as it could not be left up to individuals. Cali explains that the shift away from the production of goods by individual craftsmen bought about the introduction of the assembly line between 1900 and1940 in America where products passed consecutively through various operations. Cali describes how ‘Standardisation became the trend’ adding that the prevailing management thinking at this time centred around keeping jobs simple and under close supervision. The expectation was that workers would meet standards only if closely supervised. The 2nd world war played a key role in the evolution of TQM. Factories geared up for mass production and were split into functional departments. At the end of the war, America undertook the rebuilding of Japan’s shattered economy. Amongst the many Americans that were sent to Japan to support this effort was Dr W Edwards Deming. He was instrumental in convincing the Japanese to adopt the principles of industrial efficiency and thus the development of the TQM theory was born. He advocated a climate of ‘continuous improvement’. â€Å"Listen to me† Deming told the Japanese â€Å"†¦and in 5 yrs you will be competing with the West. Keep listening and soon the West will be demanding protection from you†. Using his TQM principles, firstly with manufacturing and then to sales and other areas, the Japanese gradually developed their own version of TQM so that by the 1970s, they had begun to dominate some of the manufacturing markets. Deming believed they had done this because they had learned a fundamental principle of TQM that was summed up by Deming: â€Å"Nobody except the Japanese understand that as you improve quality, you also improve productivity.† During the 1970s, American’s position as the world’s foremost industrial power had begun to decline. For example, the U.S. share of the manufacturing market in 1970 was down to 17% from a high in the 1950s of 35% (Cali pg16). Brown believes that the reason for this decline can be partly explained by the way American companies practised the art of inspections in manufacturing products whilst their Japanese counterparts embraced the TQM consumer needs messages promoted by quality gurus including Feigenbaum who promoted the principle that â€Å"The total composite product and service characteristics †¦ through which the product or service in use will meet the expectation of the customer† (Feigenbaum in Brown et al, 2000, pg 194). The reaction by American firms to the success of Japanese was to adopt more of the principles taught by the American TQM gurus. Cali describes how ‘Many American companies achieved success by refocusing their attention on quality and by making satisfied customers their top priority.’ During the early days of manufacturing, inspections were seen as the best way to insure quality within a business. Ho explains that this is a process by which an operative’s work was inspected on a frequent bases and a decision was made on whether or not the individuals work was at a high enough standard. At the time this was seen as an acceptable way of insuring quality in a business, it become larger as the business grew and it created many inspection jobs. However, often as a business progresses, problems can be more advanced and therefore require more technical skill which quite often inspectors did not have due to a lack of training. This resulted in inspectors ignoring problems with products in order to increase output, which obviously led to poor products giving the business a bad image. So gradually, during the post-war years (as Cali explains) â€Å"†¦ a sea change began taking place in American management philosophy.† as managers began to understand that work of employees needed to be acknowledged and that workers needed to be consulted if quality was to be improved. In Deming’s book ‘Out of the Crisis’ he explains in his fourteen principles that inspection is not the way forward if a businesses is to ensure quality. He says â€Å"Cease dependence on inspection to achieve quality. Eliminate the need for massive inspection by building quality into the product in the first place† It is around the time that we begin to see the emergence of quality assurance with more emphasis focused on the training and development of staff, recording of data and the accuracy in which things were measured. Brown et all describes how â€Å"In the 1980s, leading-edge corporations sparked a revolution as they implemented Total Quality programmes across entire organisations. In such a programme the responsibility for quality is with the whole workforce. Each employee is responsible for the quality of their own job, their own actions. It could be said that responsibility for quality lies with 100% of the workforce. Another TQM guru, Joseph Juran also influenced the thinking at this time by promoting the need for education and training in the workforce so there is no need for inspection. He added that quality should be about â€Å"Fitness for purpose or use†. By the 1990s, TQM was becoming the buzz word in the global business world. Cali says in his introduction to TQM that â€Å"TQM is destined to become one of the most frequently used acronyms of the 1990s.† He went on to say that growing numbers of CEOs in the USA and abroad believed that TQM was the â€Å"†¦wave of the future.† Part of the evolution of TQM practice was the use of statistical quality control. This was quality control by using statistical methods. It was first introduced by an American physicist and statistician called Walter A. Stewart, famously known as the ‘father of statistical control’. His work was later progressed by Deming who applied statistical control methods in America during World War 2; he applied his methods to many strategically important products thus improving the quality and output of manufacturing. The term Statistical Quality Control (SQC) is used to describe the set of statistical tools used by quality professionals in modern quality management practice. An example of this method is Six Sigma. According to Motorola: â€Å"Six Sigma has evolved over the last two decades and so has its definition.† The UK Department for Trade & Industry explains that â€Å"Six sigma is a data driven method for achieving near perfect quality†. According to Berger, Six Sigma which began in 1986 as a statistically based method to reduce variation in electronic manufacturing processes in Motorola Inc is now considered to be the most popular TQM method in the history of TQM. Six sigma is an enormous brand in the world of corporate development. Today, more than 20 years on, Six Sigma is used as an all encompassing business performance methodology, all over the world, in organisations as diverse as local government departments, hospitals, banks and multi national co operations. The establishment of modern day TQM tools and technologies such as Six Sigma brings the evolution of TQM full circle. We’ve seen that quality evolution has become the quality revolution. In a relatively short time many companies have chosen quality as a strategic goal. As noted in Tom Peters’ and Nancy Austin’s seminal work, A Passion for Excellence, explains that ‘†¦. winners compete by delivering a product that supplies superior value, rather than one that costs less’ We’ve seen from the Japanese that a focus on quality can bring success in terms of market share and profits. Companies in the West such as M & S and Mercedes Benz have shown that improved market share comes from doing the right things, all the time. Crosby very interestingly emphasizes the principle of â€Å"doing it right the first time† which means instead of having an inspection on quality, just make sure it is already up to scratch. Cali believes that the ‘process of continued improvement’ was a key stage in the evolution of TQM. He suggests that the Japanese consider quality an integral part of product and process design. Cali adds â€Å"In the United States 20-25% of production cost goes to the quality assurance personnel who find and correct mistakes. In Japan, only 3 per cent of production cost is spent this way.† Cali explains that the Japanese use TQM methods by assigning the in-process inspection to individual production workers who complete elementary statistical analyses and are authorised to take basic corrective action. â€Å"The result is greater individual pride in workmanship and higher employee motivation† says Cali. . Surely this is the essence of TQM and brings the evolution of TQM full circle? In conclusion, this discussion has attempted to explain how the evolution of TQM can be traced back to the early days of the industrial revolution with its principles of inspection and focus on measuring the product to the sophisticated systems for improving and managing quality which we have come to know today. The key point to conclude with is that the change in quality management culture from ‘if it ain’t broke, don’t fix it’ to ‘if it ain’t perfect, continue to improve it’ was not sequential nor was it down to an individual guru or country but as this discussion has outlined it evolved more through a combination of developments in inspections, quality control, quality assurance and ultimately in the way these processes were managed and delivered.

Nutritional paper

a. How did your recorded protein intake compare with the recommendation of the CNPP? Well, if my protein intake would be compared to the Nutritional recommendation of CNPP, I am not only doing well, I was able to surpass the requirement. In fact my total protein intake is around three times than the required amount. By having such a high protein diet results to a healthy living because of the following reasons: Protein aids in the proper maintenance of body tissues, Protein composes a large part of our body’s muscles, system organs, enzymes and hormones; without which one’s body can never function properly. Without significant amount of protein in our body, we can never live because proteins are one of the primary building blocks, specifically hemoglobin, which helps to bring oxygen throughout the body. The body’s enzymes are also composed of Protein, which also composes antibodies to help our body fight against diseases and viruses. Also the body needs a lot of protein to develop well. Without protein the skin will rapture easily because it lacks Elastin, the specific macromolecule that gives elasticity to the skin. b. If your recorded protein intake was too high or too low, which foods might you change to achieve your goal and keep other nutrients in balance? Protein can basically be found in fish, meat, poultry, pork, lamb, shellfish, milk, cheeses, eggs, beans, tofu and many more. So basically if I lessen my food intake when it comes to the different kinds of food mentioned above, I can normalize my protein intake. Why normalize my protein intake, considering I mentioned a lot of benefits earlier in this paper? Every time I eat too much protein packed food, I am at risk of having high cholesterol, not only that but it also gives way to kidney complications. Considering that Protein filled foods have cholesterol, it also heightens the risk of having heart attack. c. Which foods in your recorded daily intake provide protein? As mentioned above, fish, meat, poultry, pork, lamb, shellfish, milk, cheeses, eggs, beans, tofu and nuts are examples of food that I eat that provides me with more than enough protein for my daily diet. d. Is the protein in each of these foods complete, or are they incomplete, thus combining to become complementary? Considering the fact that at the end of the day, I was able to eat tree times the recommended protein intake, I can definitely say that the protein in the food that I eat on a daily basis is complete. Not only that, but the food that I eat with protein has other food groups such as carbohydrates, and fats, hand in hand with vitamins and minerals that is good for my everyday diet. e. How much of your daily recommended protein intake did you achieve? Were you surprised by that number? If your protein is not where it needs to be, what can you do to bring it into the recommended range? Be specific. I was able to achieve 165gm (294.64 %) protein intake considering that the normal protein intake is 56gm (100%). I am surprised considering that I ate more than enough protein filled foods that what was recommended. Needless to say, I don’t need to increase my protein consumption but instead lessen it. f. Why is your protein intake within a recommended range important? What are the effects of too much protein? What happens if you consistently eat too little protein? If I eat less than what was recommended amount as I was explained above will hinder my body’s metabolism, weaken my muscle structure, weaken my immunity and decrease the amount of oxygen that flows through my blood. Another bad effect of too little protein intake would result to the slow rapture of the skin, and also my internal organs. g. Did your fiber total meet 100 percent of the recommendation for you as calculated by the CNPP website? I was only able to achieve a total of 71.79 percent of the goal when it comes to fiber intake. Since I barely passed my fruit and vegetable consumption requirement I was not able to take in enough fiber in accordance to the daily recommendation; considering that vegetables and fruits are the food groups which are considered fiber rich. Similar:Â  Nutrition h. Did you think your intake was too high, too low, or just right? Why do you think so? Fiber rich foods are important because they aid in proper digestion, plus they don’t have any bad effect in our body. So therefore it is not a question of having too much fiber but instead having too little fiber intake. Considering I was only able to reach 71.79 % of the recommended fiber intake, I think it is low and should be improved so that I can at least aid my body in the digestion of everything else I eat. i. Did your diet meet the minimum number of servings of foods from each fiber-containing group? Considering I ate enough vegetables and fruits to fulfill the daily requirement, I think I was able to eat enough fiber-containing food. The only problem is that I was not able to eat fiber-rich food. j. If you did not meet your minimum fiber requirement, which fiber-containing groups (fruits and vegetables) fell short of the recommended intake? Fruits can be considered the cause since I was only able to eat enough fruits to meet the requirement. Plus, not all fruits are as fiber rich as pineapples. k. Which specific foods provided the most fiber in your day’s meals? Which provided the least? Identify trends in your food choices that would affect your fiber intakes. Fruits and a various vegetables provided me with the fiber I needed. Grain has a small chance of having fiber but it still has some. But meat and milk has no fiber at all considering that they complete most of my diet would be the cause for my lack of fiber. l. What alterations might you make among your vegetables, fruit, meat and alternatives, or grain choices to increase the fiber in your meals? Possible alterations on my meals would be as follows: Eating oats, brown rice, mountain rice and unpolished rice instead of the normal type of grains; eating high fiber fruits such as Pineapples, Blackberries and Blueberries; eating meat that contains less fats so that my body wont need that much fiber to clean it out of my system; and eating a lot more vegetables, specifically the green type of vegetables. m. What contributions do meats and milk products make to the day’s fiber total? What advice about fiber would you give to someone who emphasizes meat and milk products at each meal? How would you tell him or her to change his or her diet? What foods would you tell him or her to include in his or her diet? Meats and Milk does not contain any fiber what so ever. Basically, if one prefers to eat an all meat and milk diet, one will not receive a single ounce of fiber in what they will be eating. Therefore I would suggest that the person increase their fiber consumption by eating unpolished rice, oats, fruits and vegetables. n. Did your meals include fiber-rich bean dishes such as chili, beans in a salad, or split pea soup? Anyone interested in obtaining fiber should find ways to eat some legumes each day. Unfortunately my diet does not contain much of all the beans included above, but knowing perfectly that I have to eat legumes such as beans I will decide to include it much more often than I already do. o. If you chose to drink fruit juice instead of to eat whole fruit, what would happen to the fiber content of your diet? If you chose to drink purchased fruit juice instead of to eat whole fruit, what would happen to the calorie content of your diet? There are some pros and cons when it comes to drinking fruit juice versus eating whole fruit. First of all, whole fruits contain more fiber than any juice drink can possibly have. On the other hand, fruit juices have fixed amounts of calories, vitamins, and carbohydrates such as fiber, therefore it is much easier to control ones intake of calories than simply estimating it when I eat whole fruits; since fruits are not all have the same sizes and nutritional content.

America and its Past war economy essays

America and its Past war economy essays There is very little doubt that a true war is one of the most economically sound events in which a government could participate. War is good for business. Excluding the enormous cost of life and other social and political ramifications, war is one of the best things that can happen to a society. Both Malthaus and Marx argue that capitalist societies require war to survive and expand. Throughout history there are many examples of how wars have stimulated economies and created new avenues of development for industry. In fact much of the development of countries such as the United States, happened during and directly after wars. Erik Janeway insists that War had been the direct and immediate cause of Americas cycles of expansion. War has become an increasingly good opportunity for businesses and government. This was particularly so after the employment of Keynes economic theories in World War Two. Keynes suggested that in order to stimulate an economy, there must be an increase in deficits. After this increase in deficits, more and more employment will be created, spending will increase and the wealth and more importantly industry of the country will increase. This is actually the basic model of a wartime economy. As soon as a government becomes aware of a conflict or a threat to national security, it begins to allocate large amounts of money to weapons and other defence measurements. Demand for weaponry and defence machinery is usually greater than peacetime arms industry can cope with, and expansion of industry occurs, and naturally the rate of unemployment drops. There is also room for technological development, as the government is evidently eager to create newer, more technologically advanced weaponry that will destroy the enemy. With so much extra spending, wartime economies begin to boom. More people are in employment, not only through industry expansion but also throu...

Sickle cell anemia Essay Example | Topics and Well Written Essays - 1250 words

Sickle cell anemia - Essay Example value to carrying a single sickle-cell gene in these areas because people with only two alleles of the gene are much less likely to fall victim to malaria (Kwiatkowski, 2005). The condition is characterized by the shape of the individual’s red blood cells, which tend to adopt a rigid, abnormal ‘sickle’ shape to them that decreases the cell’s flexibility and can create a number of complications throughout the body as a result. This occurs as a result of a mutation in the hemoglobin gene and it affects approximately 1 in 5,000 Americans, most of who are of African American descent. The life expectancy for people with sickle cell anemia is shorter than normal averaging 42 for men and 48 for women (Platt, Brambilla & Rosse, 1994). The purpose of the present research is to identify the genetic origins of this illness and the affects it can have upon the body. There are a number of different forms of the disease which are classified based upon the mutations present within the blood. Sickle cell anemia is the term used to specifically apply to those individuals who present homozygosity for the mutation (Green et al, 1993). In these individuals, long-chain polymers of HbS have the effect of changing the normally smooth, donut-like shape of the red blood cells to a more spiked and rigid shape that makes the cell more susceptible to breakage. People who are heterozygous for the illness are generally carriers, having only one sickle gene and one normal gene that generally makes up for the deficits of the sickle gene. However, when the ‘normal’ gene is also abnormal in some way, other forms of the illness can manifest, typically referred to as compound heterozygous (Green et al, 1993). The sickling effect is caused by a point mutation in which the glutamic acid, a type of amino acid, is replaced with valine, a hydrophobic amino aci d, at the sixth position. When in low oxygen conditions such as being at a high altitude, this causes an aggregation of

Religion and Music Research Paper Example | Topics and Well Written Essays - 1000 words

Religion and Music - Research Paper Example People face numerous situations where they are compelled to listen to music whether by choice or without it. Even in our Muslim state no matter where we go we are required to listen to music. Restaurants, department stores, homes, cars there is no place where music isn’t played. With the availability of cell phones, I pods and so many electronic gadgets like these have eased the access to listening to music. It is imperative for us to know that what our religion teaches us about music and to what extent it permits us to listen to it. For this we need to refer to the Quran, Hadith and sayings of the Rightly Guided Caliphs and Prophet’s companions. According to these sources, music has been termed as ‘haraam’ in our religion. Interpreters of the Holy Quran have identified the term â€Å"lahwal hadith’ as listening and singing songs, buying singers and buying instruments for amusement. Sayyidana Abdullah Ibne Mas`ood, a close companion of the Holy Prop het was inquired the meaning of the phrase â€Å"lahwal hadith’ and he answered, â€Å"I swear by Him besides whom there is no other God, that it refers to ghinaa (singing).† It is believed that he repeated this statement thrice and his views have been seconded by the Four Caliphs, the prominent Sahaba and other reliable personalities in Islam. Music is forbidden and also regarded as a major sin in our religion. Playing of musical instruments is also a major sin hence it is haraam to play the guitar, piano, drums etc. Imam Ali ibne Musa Reza says, â€Å"And to be engrossed in musical instruments is also one of the great sins.† (Bhimji) A verse from Surah Luqman in the Holy Quran is often offered as a proof of prohibition of music, ‘And there are among men those who purchase idle talk in order to mislead others from Allah's path without knowledge, and who throw ridicule upon it. For such there will be a humiliating punishment.† The word â€Å"idle t alk’ here refers to the word ‘lahwal hadith’ which has been discussed earlier. This word has been interpreted in two more ways but they refer to shirk (polytheism) and diverting people from Allah’s worship which takes us to the same idea of engaging in prohibited activities. (al-Kanadi) However there are contradicting views that can be found among people and some misinterpret that music is permitted in our religion. The Quran says, â€Å"And verily, We did favor some of the prophets over others, and to Dawood We gave the Psalms†. This verse of the Quran is not a proof for those who consider music being legal. Psalm (Zaboor) was the Holy Scripture that was given to Hazrat Dawood by Allah and it contained teachings of wisdom and talked about Allah’s greatness. Nowhere in the holy book is it mentioned that music or musical instruments are allowed. The truth is that Prophet Dawood was blessed with a melodious voice which was intensely beautiful a nd captivating that when he recited the Zaboor men, birds, animals and jinn gathered around him to listen to his recitation. This in by no means indicate that Zaboor was reveled with musical instruments or talked about music.(al-Kanadi) Some people believe that another verse from the Holy Quran relating to Prophet Ayyub permits music and dancing. Allah the All Mighty, commands Prophet Muhammad in Holy Quran, "And recall Our servant, Ayyub, when he cried unto his Lord, 'Verily, Satan has afflicted me with distress and suffering.' It was said unto him, 'Strike the ground with your foot; here is a spring for a cool bath and water to drink†. Many Sufis have taken the phrase ‘Strike the ground with your foot’ as an act for allowing music and dancing however the tafseer of the Holy Quran re

A Journal opinion article Essay Example | Topics and Well Written Essays - 750 words - 3

A Journal opinion article - Essay Example This has been the driver of social sites like facebook and twitter. The two issues are commanding a large market and therefore very important in economic development. Many would agree that people want to feel happy. This is quite paradoxical in the economic perspective. Philosophers agree that money is not the sole reason to happiness but rather it is just a means to fulfillment. Through research, it has been noted that the relationship between income in monetary terms and happiness or a feeling of fulfillment is quite complex. This seems partly affected by the fact that availability of money enables one to afford recreational facilities, holidays, retreats which are deemed to enhance a feeling of happiness. Some opine that having money doesn’t guarantee a feeling of happiness. Therefore this has remained a subject to many economic researchers who try to relate economics and community, or economics and sociology (Frey & Stutzer 63) In many countries today, job creation remains the priority agenda to development. But how does this stimulate economic growth and development? For instance, having a majority of citizens unemployed fuels society vices like robbery, drug abuse, rape, due to being idle and frustration. From these findings, it’s right to say that job creation is a key aspect to a country’s economic development. This touches on Improvement of other economic drivers as well. This may include industrialization. Job creation seems to be directly proportional to economic growth. Having a huge number of employees being paid by the government translates to high wage bill. The government will spent more amount of money to settle the salaries and wages. This means more taxes to the citizens so as to raise the money. How job creation and happiness are related is a paradox and complex. The effect of economic growth in relation to happiness differs from one country to another. Nevertheless, we can broadly categorize these into developed and dev eloping countries. In developed countries, majority of its citizens can comfortably afford basic needs like clothing, housing, food, medical care. However, this is a problem to citizens in developing countries. They barely afford three meals a day, good shelter, decent clothing, medical care and basic education. This may be a crucial parameter in determination of happiness. The two categories of citizens perceive economic growth and happiness differently (Frey & Stutzer 78) In developing countries, challenges faced also include pollution, depletion of non-renewable natural resources and generally, environmental degradation. This seems to fuel and accelerate the incidence of disease. Epidemiological studies and findings show that there is higher disease prevalence in these countries. High deaths may be recorded and this translates to disillusion and unhappiness. From the scenario, the affected people will incur more expenditure in pursuit of medical services and treatment. Cash flow will be altered at family level, cumulatively affecting the economic landscape of the entire community. Therefore the wellbeing of a person or group of people affects the economic development of the entire niche. The aspect of social wellbeing and economic growth tend to intertwine. Politics is a major factor to economics. Political stability or instability determines the investment patterns of a country. Leadership plays a role in public policy which may favor economic growth or derail it. Unstable governments leadership systems tend to repel

The Hardy Weinberg Theorem In Genetics Biology Essay

The Hardy Weinberg Theorem In Genetics Biology Essay Introduction The Hardy Weinberg Theorem is a mathematical formula that allows allele and genotype frequencies in a population of diploid or polypoid individuals to be interrelated, where the frequency of one allele is represented as p, and the frequency of the other is represented as q (the sum of which = 1.0). The sum of the different genotype frequencies (homozygotes and heterozygotes) also equates to 1.0. Where p and q are the frequencies of the alleles for a particular gene in a population, the genotype frequency can be expressed as: p ² + 2pq + q ² = 1 Where p ² = frequency of organisms that are homozygous for the first allele q ² = frequency of organisms that are homozygous for the second allele 2pq = frequency of heterozygous organisms The Hardy Weinberg equilibrium stays constant as long as there is random mating, no migration, no natural selection, no mutation and no genetic drift (N=infinite), (Fig. 1). N = infinite Figure 1. A graph to show the Hardy Weinberg Equilibrium. Put together using data from: Lori Lawsons lecture 15, Neutral Evolution and Genetic Drift, 2010 Therefore the population does not evolve. If an allele or genotype frequency is seen to change from one generation to the next then it is clear that one or more of the micro-evolutionary forces (mutation, migration etc) are acting on those traits in the population. Without mutation there are no new alleles or genes and so no evolution. Mutation must occur in the germ line to be significant in evolutionary terms. J. B. S. Haldane (1892-1964) stated that the number of germ cell divisions per generation is higher in males; therefore the mutation rate will be higher in males. Gene flow (also called migration) brings new genotypes into populations and is critical for the long term survival of a population, especially if it is a small population. For migration to be Catherine Carrick 200884273 effective in respect to evolution there must be successful reproduction among migrating populations. It is the movement of alleles between populations, not individuals. Wrights Island model of migration (Fig. 2) shows that migration homogenizes populations (where they consist of similar elements uniform throughout). Genetic drift is another form of micro-evolution and leads to random changes in allele frequencies. It is fundamentally a result of finite population size and has the most rapid and dramatic effect on small populations who show reduced variability. Drift increases divergence between populations so genetic variation must be replenished. Mutation replenishes variation and at equilibrium there is a balance between the rate of mutation and the rate of drift. Figure 2.Wrights island model. Put together using data from: Lori Lawsons lecture 15, Neutral Evolution and Genetic Drift, 2010 Charles Darwin (1859) defined natural selection (another micro-evolutionary force) with his four postulates; 1) individuals within populations are variable, 2) there is heritability (variation among individuals partly passed on from parents), 3) that in every generation there are some individuals that are fitter (survival/reproductive success) than others and 4) fitness is not random. Natural selection is the equivalent of differential reproduction as a result of an organisms interaction with the environment and the populations inherent variation. It acts on heritable (not acquired) characteristics at an individual level and not for the good of the species. However, the consequences occur in populations. This is demonstrated by melanism in the peppered moth (Biston betularia). The causes of melanism in the peppered moth have been well studied since the 1950s and show natural selection at work. Camouflage is key to predator avoidance in the peppered moth and there are two distinct mor phs. One being white with black or brown specks (typica) and the other predominantly black (carbonaria). The former is well camouflaged on trees with lichen on their bark and the later; better suited to dark or blackened bark. During the industrial revolution in the 19th century, an increase of soot and industrial pollution coincided with the appearance of the carbonaria form. Original studies on the relation between B. betularias crypsis and lichens failed to consider two important details; firstly, that the natural resting place of the moths is high in the canopy during the day and not on the trunk as previously thought, and secondly, human vision was used to simulate a birds view of the moths originally, but avian species are sensitive to different wavelengths of light and so will have a different view of the moths and their respective camouflage to that of humans. Taking this into consideration, Majerus, Brunton and Stalker (2000) devised a more systematic experiment to examine the UV characteristics of Catherine Carrick 200884273 both moth morphs and some of the lichens they rested on as demonstrated by the images in Fig. 3. Figure 3. The typica and carbonaria forms of the peppered moth as they appear in normal visible light (a), and as they appear under UV light (b). Image taken from MAJERUS, BRUNTON STALKER, 2000 It was their conclusion that moth colour provides sufficient camouflage both in human-visible and UV- spectra to crutose lichens (as appose to different lichen flora originally hypothesised to be rested upon by black and peppered morphs). Ultimately, strong selection pressures gave way to relatively rapid the evolution of the carbonaria form in industrialised areas due to the advantages of its dark colour (predator avoidance etc). Methods and Results Assignment 1: Testing the Hardy-Weinberg Principle: Method Using PopGenLab, we are able to set up hypothetical experiments to observe the factors that influence the Hardy Weinberg equilibrium in a population. We can do this by manipulating different input parameters (genotype frequency, tree type, number of stands (groups of trees), stand size (number of trees within a group), migration rate, mating pattern and disaster frequency). For this assignment the input parameters are as follows: Number of stands = 1 All other input parameters are left at default values (equal allele frequencies; genotype frequencies of 50% brown, 25% white, 25% black; equal proportions of each tree type; stand size of 4000; no migration; random mating; disaster frequency set at Never. Results Q 1.1) When looking at the allele and genotype frequencies, there is a change in both over time. All populations behave differently to one another. This is because the only active evolutionary force is genetic drift. Fig. 4 shows that allele frequencies change Catherine Carrick 200884273 over time due to genetic drift, but as all the conditions of the Hardy Weinberg equilibrium are fixed the allele frequencies must equal 1 and so the variation in allele frequency of A becomes the negative of the frequency of a. (Fig. 4). Figure 4. Showing allele frequencies changing over time due to genetic drift. Blue line = Allele A, Red line = Allele a, Green line = average over all stands for allele A Q 1.2) When the initial allele frequencies are changed to A=80% (p), a = 20% (q) (p ² = 0.8 x 0.8 = 0.64); AA = 64% (equilibrium reached after one generation) (Fig 6). If all the Hardy Weinberg conditions are all fixed, the equilibrium will always be reduced in the next generation (Fig.5 and 6). Fig. 5. shows the initial genotype frequency compared with Fig. 6. which shows the genotype frequency after one generation. The actual genotype frequencies (worked out with average stand number) match the Hardy Weinberg predictions as they stay within 1% of the previous generations genotype frequency, across every generation thereafter. However, the percentage may change by 1% due to genetic drift. Figure 5. Display of the initial genotype frequency. Catherine Carrick 200884273 Figure 6. Shows the Hardy Weinberg equilibrium is reached after one generation where 0.64=64% homozygous AA individuals. Assignment 2: Genetic Drift Method Q 2.1) Firstly we ran an experiment with default values for all the Hardy Weinberg conditions and 100 populations. We then ran a series of experiments with 100 populations and default parameters for all conditions except tree stand size which was systematically reduced for each experiment. We recorded the effects on allele and genotype frequency (below). Fig. 7 shows that stand size 10 produced the largest fluctuations of allele frequencies, and displayed the most cases of allele fixing. Results Stand size = 4000 (carrying capacity) Allele frequency- the average remains constant for A and a Genotype frequency stays relatively constant throughout. Stand size = 2000 Allele frequency the average show slight variation Genotype frequency stays relatively constant. Stand size = 1000 Allele frequency the average starts to diverge more with each generation from F45 (generation 45) onwards showing a lot more variation than in larger stand sizes Genotype frequency the average frequency stays constant although there is some variation compared with larger stand sizes Catherine Carrick 200884273 Stand size = 500 Allele frequency The average shows variation in the later generations Genotype frequency the average stays relatively constant but still with more variation than in any other larger stand thus far Stand size = 250 Allele frequency the average shows some variation in the mid-generations, but this returns to a 50:50 frequency in the later generations Genotype frequency on average, the frequency of both white and black variations of moth increases and shows a large variation between stands. Heterozygosity the brown variation decreases by 9% over 100 generations Stand size = 100 Allele frequency the average shows more variation, but to the point where in some stands alleles within individual populations become fixed Genotype frequency the frequency of homozygotes increases. In some stands the homozygosity (black) becomes fixed, phasing out the other tow variations (white and brown) Heterozygosity drops by 22% Stand size = 50 Allele frequency frequencies become fixed for a single allele quickly (by F23) Genotype frequency Many stands become fixed for one variation within a few generations Heterozygosity drops by 33% after 100 generations Stand size = 10 Allele frequency becomes fixed within a population after two generations, and continues to become fixed in other populations. By F77, all are fixed Genotype frequency every single genotype becomes homozygous or extinct Heterozygosity by F77 all heterozygosity is lost and by F100 there are only homozygous populations, with the other (70%) becoming extinct There are many variations in allele and genotype frequency between different stands because as the stand number decreases, the chance of genetic drift increases. Figure 7 shows that at stand size 10, heterozygosity was lost completely by F77. Catherine Carrick 200884273 Figure 7. (stand size 10): this produced the largest fluctuations of allele frequencies, and displayed the most cases of allele fixing. (Blue = A, Red = a, Green = average) Q 2.2) As the stand size decreased, so did the heterozygosity. Populations began fixation in stand size 100 to stand size 50. As the stand size decreased, the number of fixed alleles increased. When the carrying capacity became too small, there was not enough variation to prevent fixation. Random mating account for the variation between fixed and non-fixed alleles in stand size 100 and stand size 50. Fig. 8. shows that with a stand size of 10, heterozygosity diminished completely by F77. Therefore, the smaller the population, the quicker heterozygosity is lost. Figure 8. Question 2:2 (stand size 10): This shows the heterozygosity diminished completely by F77. The green line (average) tends to diminishing heterozygosity. Catherine Carrick 200884273 Figure 9. Question 2:3 (stand size 10): Shows population of stand number 15 and how it fluctuates around the average value, it also shows that when the population dwindled to a certain point, it wasnt able to re-establish the numbers enough to prevent extinction. Q 2.3) Yes populations from stand size 10 became extinct (70% of them) therefore, as the carrying capacity decreases, the risk of extinction increases. There is variation within generations due to factors like predation or whether the offspring are male biased for example. There may be a lower population size in the next generation depending on mating strategies (random mating) and occasionally, the parameters reach a point of no return and the population can not recover and so becomes extinct. Others avoid extinction because the experiment is random. Fig. 9. (where stand size = 10) shows population of stand number 15 and how it fluctuates around the average value, it also shows that when the population dwindled to a certain point, it wasnt able to re-establish the numbers enough to prevent extinction. Assignment 3: The Influence of Mating Patterns on Population Genetics Method In this experiment we set all default parameters except for the number of tree stands which was set to 100. The first experiment was carried out with random mating, and the subsequent experiments with non-random mating. We then varied the population size as before, this time to compare the effects of assertive mating with genetic drift. Results Q 3.1) The effects of 25% assortative mating: Genotype frequency 25% assortative mating causes an increase in homozygotes, and heterozygosity is lost by F80 Allele frequency (produces a sigmoidal shaped graph). All become fixed for a single allele. Heterozygosity the average heterozygosity is lost at F80 Catherine Carrick 200884273 50% assortative mating: Genotype frequency all homozygotes with an almost 1:1 ratio aa being slightly more dominant Allele frequency (sigmoidal graph) all fixed by F50 Heterozygosity lost by F33 (average heterozygosity) 100% assortative mating Genotype frequency quickly becomes homozygote dominated Allele frequency All fixed fro a single allele by F15 Heterozygosity Average lost by F4 Heterozygosity is lost under assortative mating. This is because heterozygotes are at a reproductive disadvantage as homozygotes will mate with like genotypes. Heterozygotes will not be produced by these matings either. Q 3.2) Results Population size 2000 (stand size), 100% assortative mating: Genotype frequency all homozygous by F4 Allele f fixed by F14 Heterozygosity average lost by F4 Population size 2000, 50% assortative mating Genotype f all homozygous by F25 Allele f all fixed by F29 Heterozygosity average lost by F25 Population size 250, 100% assortative mating Genotype f all homozygous by F4 Allele f all fixed by F12 Heterozygosity lost at F4 Population size 250, 50% assortative mating Genotype f all homozygous by F25 Allele f all fixed by F28 Heterozygosity lost at F25 Assortative mating dominates control of allele frequencies and the speed that alleles become fixed within a population compared with the effects of genetic drift (because the homozygotes are all mating with the same genotype and not with heterozygotes). Assortative mating is not dependant on carrying capacity. The size of the population is irrelevant when assortative mating is occurring. The results are similar for a high or a low population size. Catherine Carrick 200884273 Q 3.3) Method We conducted a series of experiments using disassortative mating and selected different levels of mating between 0% (random mating) and 100% (only unlike phenotypes mate). We then changed the population size from 2000 to 250 to see the effects of disassortative mating on genetic drift. Results Dissasortative mating shows that AA and aa will mate which increases heterozygosity and stabilises the population as shown in the results below: Population size 2000, 100% disassortative mating Geno (genotype frequency) heterozygote is predominant Allele (allele frequency) none become fixed. There is variation but it stays within 31% 68% variation Hetero (heterozygosity) increases in the first generation then remains constant Pop size 2000, 50% disassortative mating Geno predominantly heterozygote Allele none become fixed. There is less variation than with 100% disassortative mating. Variation is between 43% and 57% Hetero Increases in 1st generation and remains constant Pop size 250, 100% disassortative mating Geno -slight heterozygote increase Allele No fixed alleles. There is much greater variation than seen previously with a larger population size, between 21% and 79% Hetero increases in 1st generation then remains steady and begins to decrease. Remains above the initial percentage Pop size 250, 50% disassortative mating Geno heterozygosity increases steadily Allele No fixed alleles. Variation is less than with 100% disassortative mating and population size of 250. Variation levels out between 33% and 67% Hetero increases in the 1st generation and remains constant with a few small fluctuations which level back out Q 3.4) There would be more heterozygosity in the next generation when disassortative mating occurs and if this kind of mating is maintained, the effects of genetic drift occur much slower because the populations are prevented from diverging. Fig. 10 shows the comparison between disassortative mating and random mating where random mating allows genetic drift. Drift can still occur during dissasortative mating when the carrying capacity is very low. Catherine Carrick 200884273 Figure 10. (picture on left): Random mating, pop size 250 showing genetic drift acting to diverge allele frequencies. (picture on right): 50% dissassortative mating, population size 250 shows that dissasortative mating acts to counter genetic drift. Q 3.5) Method For this experiment we varied the initial genotype frequency for assortative and disassortative mating. We tried experiments where the initial allele frequency favoured one or the other allele. Fig. 11 show starting frequencies of 50/50% assortative mating. A small deviation in starting frequencies affects the final fixation percentages (Fig. 11). We did not include the brown allele in this experiment as the extra variable is not needed. Figure 11) Shows starting frequencies of 50/50% (50%-white allele, 50% black allele) with assortative mating = 100%. Small deviation in starting freq effects final fixation percentages. Catherine Carrick 200884273 Results Under dissassortative mating the time taken for equilibrium to establish is negatively correlated with the degree of deviation from a 1:1 starting allele ratio. Under assortative mating, fixation or loss of alleles is negatively correlated with the degree of deviation from a 1:1 starting allele ratio. Assignment 4: Modes of Natural Selection Q 4.1) Method In this experiment we investigated how fitness affects changes in allele frequency in the population. We began with default parameters except tree stand number (set at 100) and genotype frequencies. We changed the tree frequency to set up several experiments under conditions of directional selection for dark moths, directional selection for light moths, balancing selection favouring the brown moth, and diversifying selection favouring the dark and light moths. We tried experiments with the different conditions of selection and initial allele frequencies near zero and one. Results Directional selection for black moths where they tree frequencies are 50% black, 25% white and 25% brown trees gave the following results: Allele frequency becomes fixed rapidly by F10 (on average by F9) Genotype frequencies at F10 genotype becomes fixed for black allele In a small population, alleles become fixed more quickly but in larger populations allele frequencies are not affected as much. We kept the population size high so we would not see genetic drift in the experiment (4000 carrying capacity) with tree frequencies of 35%, 32% and 33%. Even the small amount of selection (35% black trees) shows fixation of alleles for the black morph of moth (Fig. 12). Selection for light moths gives the same results as selection for black moths. Figure 12. shows allele becoming fixed rapidly, due to a tiny increase in black trees on left, white trees on right (35 %) Catherine Carrick 200884273 Q 4.2) Starting figures are as follows: Black tree 25% Allele black 25% Brown tree 50% Allele brown 50% White tree 25% Allele white 25% After one generation, allele frequency remains stable (between 48% and 52%) and the genotype frequency becomes predominantly brown. This is because there is always the presence of black and white genotypes which cause slight variation. If you change the selection of trees to black 10%, white 10%, brown 80%, almost identical results occur (between 49% and 51% variation in allele frequency = stabilized). Q 4.3) To show diversifying selection we set the tree types to 45% black, 45% white and 10% brown. Genotype frequency by the 1st generation, there was a large decrease in brown morphs of moth and the equivalent increase in black and white morphs. This continues till F5 when the black morph became slightly more dominant (on average) due to random mating. The brown morph was phased out by F18 (on average) on most of the 100 tree stands. All alleles become fixed for either black or white by F23 (49% white, 51% black) (Fig 13). Figure 13. Shows 50% black and 50% white showing a 1:1 ratio Q 4.4) Small differences in fitness are effective in changing allele frequencies. Small differences in fitness have proportionally slower rates of allele frequency change compared with large differences in fitness. We conducted additional experiments with varying proportions of tree types. The results are as follows: (Where stand size = 4000, number of stands = 100, allele frequencies = white 20%, brown 60%, black 20%, tree frequencies = white 32%, brown 32%, black 36%). Even though there are a lower proportion of black alleles (A) to begin with, those alleles will have a higher fitness than white or brown as there is a higher percentage of black tree types. Over time this will equate to an increase in black morphs. There is, however, a Catherine Carrick 200884273 point where even if the black allele is fittest but there isnt a high enough population in the first place, it will crash and not recover. Q 4.5) Genetic variation is maintained under balancing selection because the allele frequencies remain stable. There is no fixation (presuming the all mating is random). The heterozygote allele is favoured and thus balances the homozygous allele. Assignment 5: Migration Q 5.1) Migration counteracts the effects of genetic drift. (Fig 14 and 15) Figure 14. Stand size of 500 and no migration shows heterozygosity varying over all populations. Green line = average heterozygosity over all populations. Figure 15. Shows stand size 500, and 8% migration. Shows migration maintains heterozygosity and there is less deviation from the average (green line) Catherine Carrick 200884273 Assignment 6: Population Bottlenecks Q 6.1) Disaster led to the loss of alleles and reduced heterozygosity. The more disasters there where, the more decreased the diversity became. (Fig 16, 17, 18) Figure 16. Control condition Shows low drift conferred by high population sizes (4000), all other variables adjusted to give Hardy-Weinberg equilibrium. Figure 17. Disaster parameters set to sometimes as opposed to never. Individual populations prone to fixation and loss of alleles. Catherine Carrick 200884273 Figure 18. Disaster frequency set to often rather than sometimes. Loss of diversity occurs faster than in figure 13 with most populations losing one or the other allele by generation 80. Q 6.2) Disaster increased the rate of extinction. The more regular the disaster, the more extinctions. Q 6.3) Migration moderated the effect that disasters had on the population. Discussion The results of our experiments clearly show that genetic drift effects smaller populations where heterozygoisity is lost rapidly and as the carrying capacity decreases, the risk of extinction increases. The is because the proportion of individuals with a certain phenotype within a small population are largely influenced by random variation in survival, and over time, the change in proportion of genotypes in subsequent generations leads to genetic drift. If one was to aim to conserve a hypothetical species, one would expect that because it is endangered, it would be a small population. To maintain genetic diversity among this species, one would need a large enough breeding population to begin with. Unfortunately, as is the case with most endangered species, populations become geographically isolated, mainly due to human disruption of habitat. Migration between breeding populations decreases and they become fragmented. Conservation efforts may be due to natural disasters such as tsunam is, fires etc, but are mainly to prevent the constant onslaught of human activities such as illegal logging in conservation areas. Figure 17 illustrates the effects of a bottleneck following a disaster, showing reduced variability (and a small population) leading to loss and/or fixation of alleles. As with genetic drift, the way to prevent population crashes, or rather soften the effects of bottlenecks, is to encourage migration among populations. This can be achieved by implementing the protection of corridors between known endangered populations. In theory, the populations can migrate between areas, maintaining a high enough level of breeding and genetic variation, to counter the effects of inbreeding depression or genetic drift (Fig 14 and 15). An example of how corridors may re-connect fragmented populations can be seen in Bhutans Jigme Singye Wangchuck National Park (www.panthera.org). Catherine Carrick 200884273 Figure 19. Map of known tiger populations (red) and proposed tiger corridors (orange). Data taken from www.panthera.org The proposed Eastern Himalayan corridor may help towards connecting isolated populations of tigers, and thus increasing genetic diversity (if these populations successfully reproduce with one another) (Fig 19). Random mating, as apposed to assortative mating, will increase heterozygosity and stabilise a population (Fig 10). This acts against genetic drift and stops the population form diverging as quickly. In a hypothetical situation then, you would preferably allow mating to occur naturally and at random. However, some conservation efforts include that of translocation of individuals or cross breeding certain individuals from separate populations. For this to be advantageous to the species, one must consider maintaining genetic diversity by genotyping the individuals before translocation. It would be senseless to swap or breed an AA individual with another AA individual from a separate population as this would lead to loss or fixation and not increase diversity. Our studies with B. betularia in question 4 to 4.5 show that intermediates are favoured over extreme phenotypes and that genetic variation is maintained under balancing (stabilizing) selection because the allele frequencies remain stable. There is no fixation (presuming the all mating is random). The heterozygote allele is favoured and thus balances the homozygous allele. As well as considering the genetic diversity of a species and its genealogy, one must understand the species by means of observations in the field including its behaviour. Later studies of B. betularia reinforced the need for such observations as it was found to rest high in the branches rather than on the trunks of trees as previously calculated. Also, modern science allowed for the study of its UV qualities which had otherwise been unaccounted for when considering levels of predation by birds. A close study of mating patterns should ideally be assessed to ensure the outcome of migration; corridors, translocation etc will be advantageous in terms of fitness. Catherine Carrick 200884273
