Analysis Of The Ethnography Of Los Angeles Zoo - 1259 Words

Khaled Salem Prof. Pessin ENGL113A Mar 11, 2015 Life in Los Angele Zoo Last weekend, I began researching the ethnography of Los Angeles Zoo and observed the humans and animals interacting. Los Angeles Zoo includes Botanical Garden which has many entertainment activities for visitors. It also offers many shows, such as Angela Collier World of Birds Theater and Elephant Training Demonstration. Los Angeles Zoo has decent selection of animals anyone can enjoy seeing them. The zoo lies on the north of Los Angeles. It is next to Western Heritage Way, and behind Autry National Center and Museum. There are several parks surround the Los Angeles Zoo like Griffith Park, Wilson Golf Course, and Mount Sinai Memorial Park. This area is completely covered by trees and grasses. This shape gives the visitor an imaginary picture of real rainforest. There some notes on the visitors parking that it is not enough, so the visitors tend to park their cars in another spot and walk about four minute to arrive. Always arrive early to not wait for a while to get tickets. There are several zoos exist in other places. For example, San Diego Zoo is one of the most attractive park in whole California. San Diego Zoo is huge park of wild animals in Babloa Park. It has over 3,700 exotic animals of 650 species. I visited San Diego Zoo last summer, and I noticed how amazing it is. Also, it has polar bear and giant panda which is not existed in Los Angeles zoo.

Autobiography Example Free Essays

You have just completed your 300-page autobiography. Please submit page 217. To be honest, I am a really a busy person. We will write a custom essay sample on Autobiography Example or any similar topic only for you Order Now I usually stay late at work, and sometimes lose my time with my family because of work. However, there is one event that I always do two or three times in a year. I go to music concerts. Since I was young I always listened to music. I listened while studying, driving, getting ready to sleep. Music, especially the drums, has been my strength and friend all the time. The drumsticks, which have been my hands’ friends since I was in seventh grade, are still the friends of my 47 year old hands. Of course my old sticks from my young age have been broken and changed many times over, but I still consider my new sticks as the same sticks I used to have when I was young. It is rather unusual for people to think that I love playing drums because my job is not a part time job or a freelance, and that they think of me as a reticent, a perceptive, and a sensitive person who only cares about his work. Nine years ago, I organized a band, and since then our band have concerts annually. Of course the proceeds of our concert are not for our own profit making. We have our concerts to help other people through the sales of tickets and donations. I know that I can donate money personally, but I wanted to help others by doing things I enjoy and entertain other people. The audiences know that they not only enjoyed the concert, but also have contributed in aiding the needy. Our band consists of seven people each with diverse jobs; CEO, doctor, engineer, composer. Each member has successful work and is recognized in society, and even has busier lives than mine. We gather together, brought about by sympathy for the underprivileged, and the love for music, reason and freedom, even though we work in different areas. Music does not restrict and discriminate age, position, or appearance. We just enjoy the music with our hearts to forget any problems on our shoulders. We first started the band just to dissolve our stress from work and life, and as time went by, it has expanded. We are now having concerts every year. Even though we are not professional musicians, many people, friends, family, have enjoyed our music for years and come and enjoy the concert. It seems that the audiences share our goals. They also get out the burdens of life and work, to just enjoy. The applause I hear from the stage while I shout, jump, and swing the sticks feels different from the greetings I receive at the hallway at work. I sometimes get very excited as if I was an idol star. Even though I think of myself as a professional drummer once in a while, I am really a businessman deep down. I love my job that and have never regretted my decision for it. I hear about people who chose their careers on the basis of success are the ones that regret their lives. It is different for me. Even though I chose my job to be successful; wealthy and reputable, I truly love my job and do my best. However, I have stacks of documents to go through, phone calls ringing every ten minutes, reprimands from the boss, and the room without windows can sometimes make me stressful and not efficient in work. During those times I grab my drum sticks bag from the third drawer of my desk, and walk out of my office, to head for the studio to swing my stresses away on the drum.

Dulce Et Decorum Est Essays (618 words) - Dulce Et Decorum Est

Dulce Et Decorum Est Explication of ?Dulce et Decorum Est? In his poem exhibiting the gruesome imagery of World War I, ?Dulce et Decorum Est?, Wilfred Owen conveys his strongly anti-war sentiments to the reader. Through the irony found in the ending, horrific imagery, and the feeling of surrealism woven into the poem, Owen forces the reader to experience the war, and therefore feel almost as decisively about it as he does. Owen applies the rhetorical situation, sensory imagery, and figurative language to contribute to the power and anti-war sentiment of the poem. The rhetorical situation in the poem helps to make the reader accept the poem's message by showing that the speaker may be trusted to be knowledgeable about the subject at hand. The poem would be far less effective had the speaker not personally experienced the vicious and cruel world war provides. Another effective element of the rhetorical situation is that the audience addressed in the poem is the person who would not tell with such high zest/ To children ardent for some desperate glory/ The old lie (25-27) if he himself had been to war. The speaker has been robbed by the deceitful notion of the sweetness of war; childhood and innocence are no longer fathomable. Essentially, the poem becomes an accusation and the reader, like a bell, can clearly hear bitterness in the speaker's voice for having been deceived so greatly. Owen uses paradoxical sensory imagery to communicate his early illusions of war's heroic glory soon dissolving into a hellish reality. The speaker in the poem must distance himself from the pain and suffering before his eyes, and so he turns away from the haunting flares (3). The phrase blood shod (6) early in the poem is an example of the contradictory truths of war- soldier's boots are made to protect his feet from pain and injury. In this instance, however, Owen compares the feeling of protection with the appalling image of bloody pain to express the irony and senselessness in war. With gas shells dropping softly behind (8), the word softly appeals in a positive manner to our tactile and auditory senses, yet this is being said about lethal weapons. In this image, Owen again presents an unexpected and paradoxical picture of war. The speaker, emphasizing that he is behind misty panes (13) as he witnesses the dramatic and grotesque death of another soldier, spares no detail, leaving the reader to deal with sudden, shocking emotions summoned in response to the sensory horror. The figurative language in the poem allows the reader to share in the speaker's sense of open-mouthed wonder at the situation. Owen states that Men marched asleep (5): a virtual impossibility, the metaphor represents the complete exhaustion endured by the soldiers. The green sea (14) of gas in which the soldier is drowning (14) depicts the dreamlike circumstances as the speaker perceived them- similar to the alseep metaphor, where only in an alternative reality state would the atrocities of war be tolerable. The incurable sores on innocent tongues (24) declare the absurdity and injustice of war. Owen's figurative language highlights the complete irrationality of war with an austerity that gives the poem much of its irrefutable power. Owen clearly communicates his aversion to war through the use of the rhetorical situation, sensory imagery, and figurative language in his poem. Not only does he covey his own feelings through the speaker, but he also succeeds in inspiring similar feelings in his readers by forcing them to encounter the horror of war. Through all of the above devices, Owen's poem Dulce et Decorum Est conveys its purpose to the reader in a thunderous and powerful voice. Bibliography none necessary Poetry Essays

A Hero Like a Hurricane

A Hero Like a Hurricane “Im your RA Katrina, like the hurricane,” she had said when we first met. It sounded strange, a bit intimidating even. Stranger still was her first piece of advice, a warning to shave our heads while were still young. She was blunt, yet not offensive; confident, yet not arrogant. Even when she didnt speak a word, her presence was always unconsciously pronounced and obvious. Her enthusiastic words of encouragement and acts of selflessness, even the smallest ones, became a source of great inspiration and helped to broaden my opinions.During conversations, Katrina usually got very quiet, subliminally signifying to us that she was trying to analyze everyones opinions and personalities. She always had the last word and concluded every conversation. Her presence and humility always were clearly prominent.I still remember one night when I foolishly locked myself out of the dorm at midnight and had no other choice but to ask for Katrinas assistance.2005-8-25 Hurricane KatrinaAlthough she had just awoken, her response was swift and she quickly made her way three floors down to the far side of the building to retrieve a spare key. Perhaps she was just doing her job, but there have been other occurrences where other RAs were not as selfless and ignored their students to gain some sleep.Next year, Katrina is fulfilling her dream by joining the Peace Corps, traveling to Africa, and shaving off all her shoulder-length red hair. Her selfless goals to better the environment and her determination to achieve them, inspires me to make similar goals. As her last piece of advice, Katrina hoped to inspire us further, telling us to never waste our “one wild and precious life.”My admiration for someone only seven years older than me grew not only because of her selflessness but also from...

Discuss some of the benefits and drawbacks of studying for a Essay - 2

Discuss some of the benefits and drawbacks of studying for a university degree, Which appear to be more persuasive Refer to the text and other sources - Essay Example Not only does a degree from a university improve a person’s career prospects but it also helps him socially. His societal status improves and he is respected more. Saying that, however, does not mean that attaining a university degree is a sure shot at landing at your dream job. It is very commonly seen that graduates are jobless or working at a lowly position which is not what they had in mind when pursuing their degree. The value of a university degree should not be gauged monetarily only although that is what most people do and high paying jobs are why people pursue a degree. A university degree gives other possible benefits as well that will be detailed in the rest of this paper. Nevertheless, a degree is never a waste of investment and even if a person does not end up getting a job right away he will find that later on, when he has some experience in lowly jobs, his degree is what will set him out from non-graduates and help him get a good job. I am a single mother of four, having lost my husband a year back. I have a background in nursing and 15 years of experience in the same field. Now I have decided to move into Public Health. I am currently enrolled in the program and also working a part time job side by side. The reason I decided to pursue this degree is that I have a passion for academics and I believe that it will help me a lot in climbing up my career ladder. Yes, it is a pretty hard task managing studies, work and a family and yes, it is extremely difficult to give equal time to all, not to mention it becomes very tiring and stressful too. But then, if you want to achieve something you have to sacrifice and work hard for it. I have also planned to complete my university training as that will be counted a lot. Training and experience is always a bonus in professional life. I believe that once I have this degree I can apply for a better position and be able to earn and support my family better. Even if the results

Using evolutionary psychology to develop your own prediction about Essay

Using evolutionary psychology to develop your own prediction about communication - Essay Example He believed that laughter could be a sign of genetic fitness that attracts the opposite sex. What is not yet fully known is why men, in particular, are attracted to women’s laughter. The question is: Why can laughter make a woman attractive to men? The false alarm theory and sexual selection theory can be both used to explain why women’s laughter attract men. The false alarm theory states that people laugh to show that any possible anomaly or threat in the environment is not present (i.e. the initially thought of as an anomaly is a false alarm) (Ramachandran, 1998, p.352). It explains that laughter assures others that harm is not present in the environment, which also partially explains why laughter is done more when people are around than when alone (Provine, 1996). In connection to laughter, false alarm theory suggests that women laugh to signal that they are not in danger. They laugh when they are with men because they want to make sure that resources are saved by not sending an incorrect alarm signal. The second theory is sexual selection theory that states that laughter is attractive because it is a sign of fitness. My hypothesis is that women laugh to signal that they are not in harm’s way. This means that laughter reduces risks or perceptions of harm to men. At the same time, women laugh to show that they can take care of their children well because laughter is related to genetic fitness (Bressler & Balshine, 2006). Men are attracted to women who laugh because of lower threats in the environment and perception of women’s genetic fitness. My prediction is that men like women who laugh because the latter’s laughter signal lack of danger and ability to protect their offspring. Women’s ability to expel noise through laughter, is an indicator that they are good sexual mates because they are good mothers. In other words, when women laugh, they look sexier because laughter is connected to their ability to take care of their offspring

The adding machine by Elmer Rice Essay Example | Topics and Well Written Essays - 500 words

The adding machine by Elmer Rice - Essay Example Most importantly, being Mr. Zero is also associated with being oblivious to some serious life aspects. Mr. Zero seems to pay no attention to his needs, desires, and wants in life (Gabrielle and Sprinchorn 307). In other words, he observes a lifestyle that is notably characterized by zero personal concerns. He takes no action to develop personally and professionally, amid serious changes that are being realized around him. For example, the emergence of the adding machine is not instantaneous. However, Mr. Zero takes no effort to maneuver the situation. Conscious awareness on needs, desires, and wants would be expected for Mr. Zero, but unfortunately this is not forthcoming. Mr.1, 2, 3†¦is associated with being responsive to what is happening around an individual. Most importantly, it means taking charge and responsibility when the need arises. Here, dormancy is outweighed and outperformed by being active. Mr.1, 2, 3 has nothing to do with obliviousness. Essentially, there are actions, choices, and alternatives as far as Mr.1, 2, 3 are concerned. Killing the boss did not solve the issue between Mr. Zero, the boss, and the adding machine. If anything, Mr. Zero commits a crime for which he is tried, found guilty, and subsequently executed. In the context of being Mr. Zero, there does not seem to be any choice for his actions. The man is oblivious to his life and he, therefore, lives the outcome of whatever he does. Given that he is an accountant professional, though zero in nature, he is responsible for himself and who he is. The Elysian Fields mark a transition in Mr. Zero’s life. Mr. Zero’s execution marked his death, but the Elysian Fields bring him back when he is said to have woken up in a heaven-like setting (Gabrielle and Sprinchorn 329). Mr. Zero killed his boss over an adding machine that was set to replace him at the company. In Elysian Fields he wakes up to operate the machine, implying that his role had relatively changed. The Elysian

Niels Bohr Father Of Quantum Physics Philosophy Essay

Niels Bohr Father Of Quantum Physics Philosophy Essay Niels Henrik David Bohr was a Danish physicist born in Copenhagen on October 7th 1885. His father, Christian Bohr, was a college professor at Copenhagen University. Bohr had one younger brother named Harald, who was a mathematician, and a sister named Jennifer (Niels bohr, 1992). Bohr married Margrethe Norlund in 1912 and had six children. Unfortunately two were lost, but the remaining four would become very successful like their father. Aage followed in his fathers footsteps as a physicist, receiving the Nobel peace prize in 1975 for his collective model of the nucleus. His other sons would become a chemist, lawyer and physician (the bohr model). Bohr began his education at Gammelholm Grammar School in 1903, later entering Copenhagen University where he received his masters in physics in 1909. Soon after, in 1911, he received his doctorate. His doctors disputation was a theoretical work on the explanation of the properties of the metals with the aid of electron theory. It remains a classic to this day. The same year he received his doctorate, Bohr traveled to Cambridge where he studied under JJ Thompson. Unfortunately, they did not get along, so in 1912 he traveled to Manchester to study under Earnest Rutherford. It was here that he completed a theoretical work on the absorption of alpha rays that was published in Philosophical Magazine in 1913. Working off some of Rutherfords discoveries about the atomic nucleus, Bohr was able to develop a working model of the atom (Niels bohr, 1992). Perhaps Bohrs most important work was that with the model of the atom. Bohrs model, sometimes referred to as the planetary model, was able to provide explanation for concepts that were previously indescribable. Working off Rutherfords previous work, Bohr was able to successfully explain the spectrum of the hydrogen atom. While Rutherfords model focused mainly on the nucleus, Bohr paid greater attention to electrons. The previous model of the atom stated an electron was an orbiting planet. The problem in this flawed model was that the electron, moving in a circular path, would be accelerating. Acceleration would create a change in magnetic field, which would in turn carry energy away from the nucleus. The electron would eventually slow and be captured by the nucleus. Bohrs model expanded upon Rutherfords and solved many flaws of the previous model (The Bohr model,). Bohr discovered that the atom consisted of a small, positive nucleus, with negatively charged electrons traveling around it due to the electrostatic force of coulombs law. (Matthews 2010). Bohr stated that electrons travel only in successively larger orbits. The outer orbits hold more electrons that the inner ones and its the outer orbits that determine the atoms chemical properties (Niels bohr, 1992). Although Bohrs model eliminated many problems of earlier renderings, it was not without its own flaws. Bohrs model violated the Heisenberg Uncertainty Principle because it states that electrons have both a known orbit and radius. It also made poor predictions about the spectra of larger atoms, did not predict the relative intensities of spectral lines, provided an incorrect value for the ground state orbital angular momentum, did not explain fine structures and hyperfine structures in spectral lines and did not explain the Zeeman effect (Bohr model of the atom,). The Zeeman Effect is the splitting of a spectral line by a magnetic field (Foley). Even with these problems, Bohrs model was still important for laying a foundation for future study. Erwin Schrodingers electron could model, made possible by quantum mechanics, and would come to outdate the Bohr model in the 1920s (Niels bohr, 2009). Along with his structural model of the atom, Bohr was able to explain how atoms emit radiation. He suggested that when an electron jumps from an outer orbit to an inner one, it will emit light. His research found the wavelength of the emitted light is the same as the photon that carries the energy difference between the two orbits. This showed that atoms can only absorb and emit at certain wavelengths. This theory was later expanded into quantum mechanics (Niels bohr,). In 1930 Bohr changed his focus to the constitution of atomic nuclei along with their transmutations and integrations. He found that a liquid droplet would give a very good picture of the nucleus. He developed the liquid droplet theory which helped clarify and provide understanding of the mechanics of nuclear fission and the splitting of the uranium atom. This theory would provide an important basis for future studies in this field by Hahn and Strassmann (Niels bohr, 1992). Bohr was well known for his concept of complementarily. It helped to clarify some of the problems that he found in quantum physics. The theory stated that wave and particle aspects of nature are complementary and cannot both be true at the same time (Niels bohr,). In other words something must have either wave or particle like properties, not both. The concept of complementarity stated that classical concepts such as space-time location and energy-momentum, which in classical physics were always combined into a single picture, cannot be so combined in quantum physics (Complementarity principle,). In certain situations, the use of one certain classical concept will exclude the use of another classical concept. Bohrs views on the Principle on Complementarity were represented in a number of different essays he wrote from 1933-1926 (Niels bohr, 1992). Bohr was equally famous for his correspondence principle, formulated in 1920(Niels bohr,). This principle states that the behavior of systems described by the theory of quantum mechanics reproduces classical physics in the limit of large quantum numbers (Parker, 1983). In simpler terms, this principle is the idea that a new theory should be able to reproduce the results of older theories in the domains where those older theories work (Apply quantum principle, 1999). During the Nazi occupation of Denmark, Bohr being half Jewish, fled the country to escape persecution. He and his family left the country by fishing boat and went to Sweden. Bohr then traveled to England to discuss the invention of the atomic bomb. In 1943 he traveled to Los Alamos New Mexico to work on the Manhattan Project. He, along with other scientists, helped to develop the first atomic bomb. Because it had such a potential to cause catastrophic damage, Bohr viewed the bomb as a device that could unify nations. When the war was over, Bohr returned to Copenhagen and promoted the peaceful use of atomic weapons and energy. Niels bohr, 1992). Bohr gave back to the community by sharing his knowledge. In 1913 he held a lectureship in physics at Copenhagen University and did the same in 1914-1916 at Victoria University in Manchester. He was a professor of theoretical physics at Copenhagen University and from 1920 until his death; he was the head of the Institute of Theoretical Physics. Along with educating future scientists, Bohr was President of the Royal Danish Academy of Sciences and the Danish Cancer Committee, Chairman of the Danish Atomic Energy Commission and a member of the Royal Society and the Royal Institution (Niels bohr, 1992). Throughout his lifetime, Bohr received many different awards for his work in a variety of disciplines. The most prestigious being the Nobel Peace Prize in 1922 for his work on the atomic model. He also received the Hughes Medal in 1921, Matteucci Medal in 1923, Copley Medal in 1938, United States Atoms for Peace Award 1957 and the Sonning Prize 1961(Niels bohr,). Bohr had many other honors apart from theses medal and trophies. The institute of physics in Copenhagen was renamed the Niels Bohr Institute in his honor. On November 21st 1963 in Demark, the Bohr model semi centennial postage stamp was commemorated featuring Bohr, the hydrogen atom, and his formula for determining the difference in any two hydrogen energy levels. The atomic elements Bohrium and Hafnium were named for him along with asteroid 3948 Bohr. Towards the end of his life, Bohr began to show an interest in molecular biology. His final work, Light and Life, proposed an idea that life might not be reducible to atomic physics. It was unfinished and published after his death (Niels bohr,). Bohr passed away in Copenhagen on November 18th 1962 due to a stroke (Niels bohr, 1992). His work had an enormous impact on the scientific world of both his time and today. His extreme strides in developing the model of the atom led to the creation of an accurate model necessary for study in modern physics. His numerous formulas solved many existing problems and would lay the groundwork for future studies. If it were not for Bohrs passion and dedication to science many modern concepts would not exist today.

Teaching Argument Evaluation in An Introductory Philosophy Course Essay

Teaching Argument Evaluation in An Introductory Philosophy Course ABSTRACT: One of the greatest challenges in teaching an introductory philosophy course is convincing students that there are, indeed, reliable standards for the evaluation of arguments. Too often introductory students criticize an argument simply by contesting the truth of one of its claims. And far too often, the only claim in an argument that meets serious objections is its conclusion. For many students, the idea that an argument displays a structure which can be evaluated on its own terms is not very difficult to grasp. Unfortunately, the idea is grasped only in an abstract way, with insufficient appreciation of how structural problems manifest themselves in concrete arguments, and without the vocabulary for formulating structural criticisms. But this paper is not simply about teaching logic, it is about pedagogy. Our task is to instill in the student the habit of clear thinking. When we send our students out into the world, we have to ensure that they are prepared for it. Introduction One of the greatest challenges in teaching an introductory philosophy course is convincing students that there are, indeed, reliable standards for the evaluation of arguments.

Assignments: Several chain syllogisms. Session 6 This session should be devoted to the examination of the limitations of term logic. It has proved useful to consider simple arguments that make use of very basic truth-functional logic (modus ponens, modus tollens, and the hypothetical syllogism are easily enough explained). While these can usually be translated without too much effort into the form of a categorical syllogism, the awkwardness of doing so is clearly prohibitive. At this point, however, the battle is already won. The students are actively engaged in the logical analysis and evaluation of arguments.

Geronimo, Apache: A Defined Leader Essay

Geronimo, or Goyathlay, was a great leader from the Native American Bendokohe Apache tribe. Although Geronimo was not a chief, the tribe depended on the wisdom of his position as medicine man. Geronimo gathered such influence that he led the last force to formally capitulate to the United States by upholding the core Apache values that embody aspects that define a leader: aggressiveness, diligence, and courage. Geronimo displayed the core values of the Apache tribe, that of courage, diligence, and aggressiveness. These core values were what kept them relatively safe from the increasing white settlement of the west, including Arizona and New Mexico (theinitialjourney.com.) Aggressiveness, or assertiveness, and diligence are key aspects of a leader. A leader must be assertive as well as persistent in order to maintain a certain level of self-confidence and influence over those who are being led, even in the face of adversity. Geronimo was a great example of an assertive leader. Geronimo led the last major Native American Fighting force to surrender to the United States; thus having the longest resistance period. Upon the discovery that his mother, wife, and his three young children had been murdered by Spanish troops, he vowed to avenge his family by retaliating against as many Mexican settlements as possible. It was not until this time that he received his ‘power’ of seeing visi ons (Indigenouspeople.net.) It was because Geronimo held out the fight for so long, that he became the most famous Apache of all. By asserting himself and applying himself in order to uphold his values of family and justice, Geronimo became an essential force as medicine man, acting in and out of combat as a spiritual and intellectual leader of the people (not a chief.) He escaped from a reservation three times, the final time bringing thirty five warriors and one hundred nine women and children into freedom. It was through these acts that Geronimo transcended above and beyond advisor. Geronimo became an icon of freedom and persistence in the face of difficulty (indiginouspeople.net.) Through assertiveness and diligence, Geronimo led his people towards their goal of freedom, also exhibiting another leadership trait: courage. Geronimo was exceptionally courageous in the face of difficulty. After vowing to avenge his family and tribe after their murder was an extreme test of character and will. It was a desire for freedom that continued his ability to evade capture. â€Å"Geronimo, the most legendary Apache war leader, along with seventeen warriors, fourteen women, and six children had evaded capture despite pursuit by 5,000 U.S. troops, 3,000 Mexican soldiers, and numerous Indian scouts for more than six months. To the U.S. Army and the settlers in the area, the supremely resilient and determined Geronimo had personified the Apache problem and every raid on a village or wagon train was attributed to him. In the years following his surrender, Geronimo came to personify resilience in the face of overwhelming odds.† Tfaoi.com Geronimo became a legendary force against the involuntary capture of Native American Apaches. His courage against adversity compelled many to follow him. His statements of â€Å"coming from a land with no enclosures† inspired people to follow a dream of living simply as they once did; without white influence (indigenouspeople.net.) It was though this notion of courage to follow one’s true intuition in life. Geronimo was an exceptional leader, exuding leadership through the qualities of assertiveness, diligence, and courage. Geronimo led his people to freedom against white influence many a time over, evading capture the longest out of all Native American fighting forces. It was through diligence in repetition of effort, assertiveness of his character and moral intuition, and courage in the face of danger and difficulty that makes Geronimo a great leader.

Free Essays on Earning Ones Rights

The Concept of Earning One’s Citizenship Citizenship is defined as a being a citizen or a person owing allegiance to and entitled to the protection of a sovereign state. Citizen preferred for one owing allegiance to a state in which sovereign power is retained by the people and sharing in the political rights of those people. The concept of which in one of its earliest was given to us by the Romans, who had just began to understand the importance of a populace contributing to the decisions of its own fate. Modern American citizenship as we know it today was defined for us in the constitution of this nation by the founding fathers. Citizenship as they had envisioned it even back then was not free, but came with a price. A citizen was expected to carry out certain civic duties and responsibilities such as the defense of the republic, participating in state and local government, and voting on affairs of the nation as a whole. Benjamin Franklin once said, â€Å"Democracy is two wolves and a lamb voting on what to have for lunc h.

Free Essays on Earning Ones Rights Free Essays on Earning Ones Rights The Concept of Earning One’s Citizenship Citizenship is defined as a being a citizen or a person owing allegiance to and entitled to the protection of a sovereign state. Citizen preferred for one owing allegiance to a state in which sovereign power is retained by the people and sharing in the political rights of those people. The concept of which in one of its earliest was given to us by the Romans, who had just began to understand the importance of a populace contributing to the decisions of its own fate. Modern American citizenship as we know it today was defined for us in the constitution of this nation by the founding fathers. Citizenship as they had envisioned it even back then was not free, but came with a price. A citizen was expected to carry out certain civic duties and responsibilities such as the defense of the republic, participating in state and local government, and voting on affairs of the nation as a whole.

Fruits to make a fruit battery Essay Example

Fruits to make a fruit battery Essay Example Fruits to make a fruit battery Paper Fruits to make a fruit battery Paper Magnesium, due to its reactivity, has a very high potential energy, so the electrons travel from it to the copper, which has a very low potential energy due to its unreactivity. The difference in the potential is called the cell potential difference. If the difference of potential energy is large, then clearly the voltage produced by the galvanic cell will also be large as voltage is potential difference. From the electrochemical series, magnesium has a standard electrode potential of -2. 37, and copper has one of +0. 34. The difference between the potentials is 2. 71, which is large, and therefore this will mean more electrons will be conducted creating a larger current, and also the difference between the potentials will also mean a higher voltage. If the anode was zinc (-0. 76) then the difference would be 1. 1 not as large a difference as the magnesium due to it being less reactive. Other examples could be zinc and magnesium, a difference of 1. 61, lead (-0. 13) and iron (0. 04), a difference of 17 and so on. This is how galvanic cells operate, storing chemical energy that is released as electrical energy when a conductor is connected between the two electrodes. This scientific theory supports my initial prediction that the magnesium and copper will produce the highest voltage due to their potential energy difference. Evaluation: I think that the experiment went quite well. It is hard to spot anomalous results on a bar graph, but I think my results are pretty accurate, and fit my prediction. However I feel accuracy was limited and could have been improved if a set of 3 results was taken, because I only took 2, it is possible that one result could have been wrong and changed the average, while accuracy is increased with three results. : There was not enough time to do this though. I think that the results gained using zinc and magnesium were more unreliable than the others, because there were big differences between the two results that were taken. For example, using lead and zinc the first time (in the grapefruit) a voltage of 0. 17 was produced, while the second reading was 0. 49V. This could be because we didnt change the metal strips after every fruit, meaning they had been reacting with both the air and the electrolyte/fruit. Accuracy could also have been lacked due to the difficulty in cutting out equal sized strips. We had to use a steel nail of similar surface area because iron foil was unavailable. Fruits are also very unpredictable and vary. I think that we should have perhaps focused on one fruit, like the lemon, and used three different lemons to increase accuracy. This would perhaps be a more useful approach. I believe further investigations are needed to help fulfill the aim of the experiment. I think that acids and alkaline solutions should be used instead of fruits due to their unreliability. This will make the experiment quicker too. The outcome would be more predictable. The distance between the two metals in the fruit could be varied in further work to again test the voltages produced using different combinations of magnesium, iron, zinc, lead and copper. You could start them with a centimetre difference between them, and then increase this by a cm until it reaches 5 cm. A variety of fruits could again be used as a variable in this method. Other variables to be tested are the surface area of the metals and how that would affect the voltage produced, as it clearly seemed to affect my results.

Self Reflective Course Concept Essay Example | Topics and Well Written Essays - 500 words

Self Reflective Course Concept - Essay Example A brief recap on the old concept of business that dictates the main essence of establishing a business is to maximize profits. These old concept discouraged organizations against social responsibility as the accountability of the social responsibility on the part of the organizational profit could not be viewed. It is on these basis that the new concept of business was entailed which necessitated that the business carries out its activities, becomes socially responsible and maintains its customers. This was a crucial aspect for various business ventures as most of them sustained the business venture with confidentiality and loyalty from their customers. The aspect of Social responsibility can never be over-emphasized in any organization. Sir Immanuel Kant a deontologist suggested that in order for people to act morally they must act from positions of duty. He also added that it is not the various action consequences that make them either right or wrong, but the intensions or rather motives of the person carrying them. Deontological ethics refers to the ethical normative stance that determines how moral an action on the adherence of the rule and finally rules. To the business organization morals are determined by what is generally right. Aspects of giving consumers the right product quantity, disclosing enough information about the various goods and services, giving quality products are all issues covered in deontological ethics. Teleological ethics touches on morality that dictates the moral obligations and duties and distinguishes it from what is desirable or good. Ethical egoism can generally be referred to as the position accorded to the agents of morals. Those at positions that necessitates their exercise of morals. These are determined by what is in their own self interest. Their relationship to business ethics is that they all contribute to the topic on ethics and guide the ethical profession Teleological ethics touches on

Western Images of Asia Essay Example | Topics and Well Written Essays - 1000 words

Western Images of Asia - Essay Example The reason for this shared animosity (That has passed from generation to generation), is that throughout history, each religion and people have felt that their God is in fact the only God and that the other faith is filled with Heretics or Infidels. In modern times another reason for western peoples apprehension towards Islam is that they do not understand its people or customs, they may see a women wearing a veil and automatically think she is a grenade-toting terrorist. In the last 25 years there has been a resurgence of Islamic fundamentalism and many western people automatically link these groups to the mainstream Muslim population and state, this is probably the main reason people believe that Islam is a threat to the west. This is far from the case that, "Political, rather than religious, considerations have been as much the driving force in Islamic states as elsewhere. The 1991 Gulf War patently demonstrated that religious considerations of the regions countries were supersede d by their political calculations. The behaviour of Iran, Turkey, Israel, and the Arab countries throughout the war was clearly based on a pragmatic style of politics." ( Monshipouri, 2003, pg25) After the terrorists attacks on The U.S. in September 2002 further made the western public feel that the religion of Islam was a threat to the west. These attacks, carried out by a small extreme group of fundamentalists has succeeded in raising the awareness of Islamic fundamentalism in the west and raising sense of threat from the extreme version of the faith. The attacks also displayed the differences between cultures and religions, as states, "Americans have tended to believe that their institutions and values-democracy, individual rights, the rule of law and prosperity based on economic freedom-represent universal aspirations that will ultimately be shared by people all

Federal Funding of Human Embryonic Stem Cell Research Paper

Federal Funding of Human Embryonic Stem Cell - Research Paper Example During the reign of President Bush, federal funding of human embryonic stem cell research stood banned since the administration opposed the practice. Even though the federal government does not fund research that involves the creation of embryos for purposes of research, President Obama’s administration lifted the ban. The federal government funds researchers that make use of embryos created in vitro fertilization but have stayed unused. However, the move by the federal government to provide funding for human embryonic stem cell research encourages other unethical practices such as abortion. Since these scientists remain prohibited from creating embryos for the research, they would turn to other alternatives to obtaining embryos. The justification used for the research would be that embryos couldn’t be considered human. This justification is likely to be used by unethical practitioners to support their misdemeanors, for instance, those conducting the abortion. Causes of the problem James Thomson initiated the human embryonic stem cell research in 1998. Several reasons became presented for the initiation of this research on the basis that stem cells have the potential to save lives. One such cause for embryonic stem cell research would be the development of rubella and polio as a resource for developing national policy and for local institutional review boards. This became founded on the premise that the research would develop considerable biomedical knowledge not obtainable by other methods. This problem intensified due to the impact of laws on the situation stem cell research developed. The Congress under President Reagan’s reelection in 1993 nullified the requirement for approval by the Ethics Advisory Board (EAB) on embryonic stem cell research. In addition, the Congress lifted a moratorium on federal funding of embryo research, which later became banned by the 1996 Congress (Holland et al. 27-29).

Microeconomics Project Essay Example for Free

Microeconomics Project Essay An overview Facebook was realized on February 4, 2004 by an American computer programmer and Internet entrepreneur- Mark Elliot Zuckerberg. Facebook has said it will be valued at up to $96bn ( £59bn) when it sells shares to investors this month in a record-breaking flotation. The first investment from Peter Thiel was $500,000 into Facebook. Facebook has minted four billionaires: Mark Zuckerberg, Dustin Moskovitz, Eduardo Saverin and Sean Parker. The 27-year-old Zuckerbergs net worth was estimated at $17.5bn on the 2011 Forbes list of the wealthiest Americans. Moskovitz had a net worth of $3.5bn but pipped Zuckerberg for the title of worlds youngest billionaire, being eight days younger. The Brazilian-born Saverin, who left Facebook early on after a falling-out with Zuckerberg, had a net worth of $2bn. Parker, the Napster co-founder who briefly served as Facebooks president, had a net worth of $2.1bn On November 15, 2010, Facebook announced it had acquired the domain name fb.com from the American Farm Bureau Federation for an undisclosed amount. On January 11, 2011, the Farm Bureau disclosed $8.5 million in domain sales income, making the acquisition of FB.com one of the ten highest domain sales in history Nowadays, 1 in every 13 people on earth uses Facebook, more than 900m active users, with over 250 million of them who log in every day. The average user has about 130 friends, but that has expanded in. The core 18-24 year old segment is now growing the fastest at 74% year on year. Almost 72% of all US internet users are on now Facebook, while 70% of the entire user base is located outside of the US. (Source: Facebook) At the beginning, Facebook has 1 million users. In 2008, it increased to 100 million. In 2010 the number of users reached 400 million and up to 500 million within 5 months. Google- a web search engine, it is the companys most popular service. It began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in California. Technology is enhancing us as human beings and the integrating of artificial intelligence is slowly being weaved and embedded into our activities and habits almost without us noticing. This reliance that is permeating our day to day existence even extends to a reported 60% plus of all buying decisions now starting with a Google search as we start our research online rather than walk the shop aisles and asking sales attendants questions. The first funding of $100,000 for Google was provided by Andy Bechtolsheim the co-founder of Sun Microsystems. Googles initial public offering (IPO) took place five years later on August 19, 2004. The stocks performance after the IPO went well, with shares hitting $700 for the first time on October 31, 2007. primarily because of strong sales and earnings in the online advertising market. In 2004: Gmail launched, Google IPO 8 billion pages indexed. They acquired YouTube in 2006 for $1.65 billion. Android was announced in 2007 and Google Chrome was launched in 2008. The 3 charts show the Revenue, Income and number of Employee in two companies. RIVAL PRODUCTION The big question is given, why a search engine like Google to be afraid of Facebook, a social network when the field of activities of these two different companies as far as they seem completely can live peacefully. Google is famous for its searching services, the key point lead to the huge success of Google. It links to billions of Web pages, so users can easily obtain the information they want through the keywords and the operators. Google also uses its search technology for many other search services, including Image Search (photos), Google News, interactive community Google Groups, Google Maps. They also launched variety kinds of services such as Gmail, Google Earth, Google Docs, Picasa, Google Desktop, Google talk, Google Chrome, Google Translate and Android. Facebook is a social networking website for free access with more than 600 million members worldwide with hundreds of millions of activities that occur every day. The amount of data produced in a day of Facebook occupies a huge part of Internet data. Users can communicate with others, make friends, send messages and update their personal profile. Facebook has several features that users can interact such as Wall, Pokes, Photos, Status, Tag (feature of imaging applications), Facebook Notes, Facebook Username, Facebook Messages, Voice Calls, Video Calling, Facebook Subscribe. Looking closely, using the Internet for social purpose has been increasing over the years. More and more people spend longer hours of socializing than browsing so the use of the internet had tilted more on the social side. Facebook has a strong impact to our society. The social circle will suggest what to read, what to check out, where to go to and what to see. These matters may seem not important, but for the business this is such a big deal. As a result, a vast number of companies had recently shifted their focus on socializing, this led to the competition Google versus F acebook. Google is stepping into the Facebook market. Google also has promoted the search function in social network (Social Search) combined between Facebook and search engine Bing with support in 19 languages. Google Social Search helps users to find the appropriate content from the online link on their social network such as websites, blogs, articles and other content created or shared by their friends. Moreover, through many failures of Orkut (social networking and discussion), Google Buzz and Google Wave, in 2010 Google also revealed their plan about new social networking called Google Me to compete Facebook. Google Me combines best features of these social networks having failed before such as allow users check how many visitors clicked, watched, or your missed updates, provide variety kinds of games and application, control the amount of friends who have connected with your friends, stop spreading wide for what was posted. Example, both Orkut and Facebook allow users to delete the share, but this feature of Orkut is much better. This means that if you share a picture for yourself, then you want to delete them, you are allowed to erase that image on your home page, and on top of all other friends.Facebook does not do this,so Google Me is expected as a more attractive version of social networking. In 2011, Google has officially announced the Google+project, a social networking service has the functionality looks very similar to Facebook such as update status, share links and upload photos. Google+allow users to communicate separately for each group. Instead of posting a content update for everyone, Google+ allows users to display that content to the particular group (called a circle), such as classmates, colleagues, family members. Recently, Facebook is actively improving its own search engine. Old founder of the Google Wave, Lars Rasmussen, has joined Facebook, is developing a version of the search engines social networking to develop a new version called â€Å"search engines social networking†. This system will be expected to compete with the search engine of Giant Google in the future. The main purpose of the project is to develop a better search engine that can help brows through the huge amount of content created by users on social networks, as the status updates, articles, video clips and other information. Facebook expects a new email service will help them overtake Google and dominate the social networking world. In 2010, Facebook unveiled the project Titan to compete with Gmail from text messages (SMS), instant messaging (IM), email to Facebook messages. The system will combine messaging via mobile phones, email and chat messages to send to the recipients and they can reply to messages in any way. Facebook uses this project likea special strategy for competition generally on the Internet and particularly on social network. This time, there is notjust the war on email. Facebook seems want to dominate in every field. Facebook is a best place to share photos, surpassing all other services from Flickr, Picasa to Twitter even though its image quality is not high. Facebook members posted 250 million photos per day and this is the function most users use in the social network. Therefore, the Facebook pay billions for the application only works on iPhone and Android also is understandable. Moreover, they also developed a tool Facebook camera similar to Instagram. BUSINESS MODEL To understand why Google and Facebook abominate each other, it is necessary to study their business model. Facebook is now one of the largest social networks while Google is believed as the most powerful searching engine. Each tech titans have been reaping significant success in their domain. However, they both seem have the same main source of revenue is advertising. â€Å"Facebook has 901 million monthly active users (MAUs) as of March 31, 2012, an increase of 33% as compared to 680 million MAUs as of March 31, 2011. And 488 million MAUs used Facebook mobile products in March 2012†-Facebook Amended S1. With great numbers of users, people are deeply impressed by Facebook’s growth. Nevertheless, Google has crossed the 1 billion user mark, while Facebook is not far behind at 900 million however, users spend a far greater amount of time on Facebook per day, approximately 7 times higher. Top 10 Web Brand for August 2011 (U.S., Total) Rank| Brand| Total Internet Audience(thousand)| Time per Person (hh:mm:ss)| 1| Google | 176,235| 1:47:42| 2| Facebook| 163,163| 7:45:49*| 3| Yahoo| 149,072| 2:12:08| 4| MSN/WindowsLive/Bing| 134,410| 1:43:45| Read as: During August 2011, 176.2 million unique U.S. people visited Google’s websites(Source: Nielsen) In the term of valuation, after the most crucial event of Facebook’s timeline- IPO, going public, Facebook is known being in the position of Google’s 2003. The table below indicates the comparison between Google (GOOG) and Facebook (FB) in different categories such as revenue, revenue growth, operating income and gross margin as they are in the public day. That means for Google, its first quarter is when they were in Q3, while Facebook’s would be Q1 2010 As the table shows, the growth of both companies over the time is almost equivalent as Google 19% and Facebook 16%. If taking into the specific, Google growth rate is arguably more stable than its counterpart social network. The primary reason causing such deviation is that Google was well-established. The following chart will present that point more clearly Source: GOOG data YCHARTS In comparison, Facebook had a dramatic variable number and especially it was negative in the last quarter, Q9 with -6%.Probably, the company has not decided which its business model is yet (Husky Financial, Facebook vs Google: what you need to know post-IPO). Besides, the other factor affects a volatile Facebook’s development is the dependence in Zynga. There is 15% of Facebook revenue from Zynga (Forbes, By the numbers: Facebook investor checklist). According to the S1, â€Å"If Zynga does not maintain its level of engagement with our users or if we are unable to successfully maintain our relationship with Zynga, our financial results could be harmed†. The crucial income of two companies is generated from advertising. Google have recently proved their Google Adwords comes off well. Thousands of business could buy ads on Google and leads or sales with a proven positive ROI, return on investment. Advertising on Facebook shows much less convincing at this position. The stop in using Facebook’s ads is the forceful example. General Motors Co said on Tuesday (June 22) it will stop advertising on Facebook, even as the social networking website prepares to go public, with a source familiar with the matter saying the automaker had decided Facebooks ads had little impact on consumers (Reuters). When going to public in 2004, raising just under $2 billion with an initial market cap of le than $25 billion, less than a decade, Google is worth close to 10 times. The IPO gave needed capital to expand their business. This scenario maybe not actually happen to Facebook, according to the previously mention. CONCLUSION A famous Chinese quote â€Å"One mountain cannot have two tigers†. Thus, a social media site or a search engine site will gain a victory? It has not exactly answered yet. However, according to several surveys and analysis in previous parts, Google has more strengthened than Facebook for some reasons: 1. We have many reasons to access Google but only a few reasons to login in Facebook. Most of us go Facebook for chatting , sharing your thoughts , seeing new update , seeing who liked our status, and sharing from our friend or using some applications and playing games . We are busy at looking the updates rather than ads on Facebook. Nobody logins in Facebook to check or to search when they can buy a cheap T shirt or which books are famous, so on. On the other hand, Google is more useful than Facebook. We can search to know any information that we need such as which college is the best or which food is good for health. When we all open up Google for the above mentioned purposes we click on various ads and indirectly generate revenue for Google. The more we search information the more revenue we will generate for Google. 2. People use Facebook less than they used to be A recent survey showed that 34% of users spend less time for Facebook over half a year ago. They assumed that Facebook is boring, not useful, not related and not safe to keep personal information. 20% users spend more time for Facebook, 1/3 users now do not login in Facebook, and nearly 50% of users login in Facebook that stay the same. In addition, a survey from 31/5 to 4/6 /2012 with 1.036 people in America by Reuters and market research company Ipsos presented that most of 80% users never buy product or service on Facebook. As a result, many advertising companies are disappointed and do not want to advertise on facebook anymore. For example: Early 2011, Facebook earned $3.7 billion through advertising. In 2012, this revenue is slowing. In fact, General Motors has recently regained about 10 million investments for advertising on Facebook because it was not effective. 3. Facebook will be forgotten Eric Jackson, founder of Ironfire Capital, said that in 5 to 8 years, Facebook would disappear the same way Yahoo now. Although Yahoo is still making money, still profitable, still has 13 thousand employees, but Yahoo is just 10% in value compared with their peak in 2000. Basically, Yahoo! has been considered as disappeared. Whether Google or Facebook win, users also have benefit. Both companies are fighting to capture the heart of users worldwide. The competition gets its benefit because it can prevent monopoly situation. As long as the two companies keep on fighting, users will continue to gain benefits because the two companies will continue to improve, change, and figure out new features to attract users. For example: Currently, Google has extra the Google Plus to attract users and many other existent features such as YouTube, Feedburner, Chat, Analytics, and Docs. Facebook has the latest new Facebook Timeline feature. The competition between Google and Facebook is just at the beginning stage. We will be seeing more actions and tricks from both sides in future. As the main goal is to gather as many users as possible, both parties will take any necessary steps to capture users’ attention. In the future, users can get more benefit such as gifts, discounts, coupons, competition prize, lucky draws and many other events by just participating. Works Cited August 2011 Top US Web Brands.

The Autoimmune Hemolytic Anemia Biology Essay

The Autoimmune Hemolytic Anemia Biology Essay Autoimmunity is a disorder in which an organism loses its ability to recognize the self and non-self antigen, which would further lead to immune response against its own cells and tissues. Diseases that results from such abnormal immune responses are termed as autoimmune diseases. Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder in which endogenous antibodies are directed against the red blood cells and upregulated leading to erythrocyte death. This review article focuses on the types of AIHA based on the classification of the antibodies and the temperature at which they are active i.e warm AIHA, cold AIHA and mixed AIHA , based on the age of its occurance i.e adult or pediatric AIHA, causes, diagnostic techniques, diseases which may cause AIHA as a secondary disorder, treatment and its aftereffects, current and future prospectives of its studies. Abbreviations: AIHA Autoimmune hemolytic anemia, WAIHA Warm autoimmune hemolytic anemia, CAIHA Cold autoimmune hemolytic anemia, RBCs Red blood cells, DAT Direct antiglobin test. INTRODUCTION: Autoimmune hemolytic anemia (AIHA) is a disorder in which the auto-antibodies are directed against the persons own red blood cells (1). It is a relatively uncommon but not a rare disorder. It has an estimated incidence of 1 to 3 cases per 100,000 population per year (1). There are three types of AIHA based on the temperature of activity of the autoantibodies i.e warm AIHA, cold AIHA and mixed type AIHA of which warm AIHA has the most common occurance (more than 70%) followed by cold AIHA (about 20%) and mixed type has least occurance (2). Further AIHA is classified on the basis of age of the patient suffering from the disorder i.e pediatric AIHA and adult AIHA. Pediatric AIHA is from the age group of 1 to 16 (or 18) years and mostly has no underlying causes (2). Adult AIHA is from 18 years and above and is mostly associated with some underlying primary diseases. Sometimes AIHA is caused due to administration of some drugs and is called drug induced AIHA. AIHA may also be of secondary or idiopathic type. The further description of the different types of AIHA is explained below. TYPES OF AIHA: Based on the temperature at which the auto-antibodies are active: Warm autoimmune hemolytic anemia (WAIHA) It the most common type of AIHA. Warm auto-antibodies are usually IgG. It is called warm autoimmune hemolytic anemia because the antibodies have their peak activity at 370C. IgG effectively binds to the FC receptor of phagocytic cells. Hence the destruction of RBCs takes place mostly by phagocytosis. IgG may or may not fix complement. Hemolysis of RBCs also takes place in spleen. WAIHA may be idiopathic i.e when there is no primary infection causing the disorder or secondary to lymphoproliferative diseases, autoimmune diseases, viral infections, immune deficiency etc (1)(2)(3)(6). Cold autoimmune hemolytic anemia (CAIHA) Cold auto-antibodies are usually IgM antibodies. Rarely IgG or IgA antibodies can act as cold auto-antibodies. It is so called because the antibodies have their peak activity at temperature ranging from 0-40 C (1)(2)(3)(6). IgM antibodies are potent classical complement pathway activators. Hence causes complement mediated lysis of RBCs. Paraxysmal cold hemoglobinurea a form of CAIHA, is caused by cold active IgG hemolysin. It was usually associated with some underlying diseases like syphilis, measles, mumps or other viral diseases (1)(2)(6). Mixed autoimmune hemolytic anemia Both warm auto-antibodies and cold auto-antibodies are present the blood. It is more fatal than the WAIHA and CAIHA. Detection and diagnosis is also more difficult than the earlier types (1)(2)(3)(4)(6). Based on the age of the patient suffering from the disorder AIHA is classified as: Pediatric AIHA Affects the age group of 1-16 years, with a higher incidence of occurance in the first four years of life (1). It may spontaneously resolve on its own. It shows a good response to the steroid treatment. It has a severe onset and less morbity rate. Males are more prone to pediatric AIHA (2). Adult AIHA Affects the age group of 18 years and above. It is more often associated with the underlying lymphoproliferative, autoimmune and infectious diseases. Treatment is steroid therapy or spleenectomy. Has higher morbity rate compared to adult AIHA because of the difficulty or inability in treating the underlying disease (2). Based on the cause of its occurance, following are the types of AIHA: Secondary AIHA It is mainly caused due to some underlying diseases like bacterial, fungal or viral infections. The primary underlying diseases that may cause secondary AIHA are Sjogrens syndrome (10), lymphoproliferative and autoimmune diseases (2).Treatment of the secondary AIHA would also include the treatment of the underlying primary disease, for its complete remission (1). Idiopathic AIHA Has no particular underlying causes like infections or primary diseases for its occurance. Mortality rate is comparatively less than that of secondary AIHA (1). Drug induced AIHA Cause of occurance are drug molecules that binds to the surface of the RBC membrane, acts as non-self antigens, thus inducing the autoantibodies against the RBCs and further leads to hemolysis (2). Examples of the drugs that cause drug induced hemolytic anemia are Ibuprofen, Diclofenac, L-dopa, Procainamide (6). CAUSES In majority of the cases AIHA is caused due to some primary underlying diseases like lymphoproliferative, autoimmune and infectious diseases (2). For example, after the M.suis infection in pigs, warm IgG autoantibodies are directed against the RBCs and destroys it. In this case actin was the active component that played a vital role in inducing an autoimmune response. Actin acted as a target protein for the autoreactive antibody during the acute phase of the M.suis infection. The autoreactive antibody production is induced by a misguided upregulation of the naturally occurring B cells specific for self antigens, appearance of previously cryptic antigens, occurance of altered self antigens, tolerance to self antigens due to molecular mimicry. The autoimmune epitopes (in this case actin) on the RBCs may be due to contact with the proteolytic enzymes. Cytoskeleton of the RBCs gets modified by the attachment and invasion of the infectious agent. Also the infectious agent causes damage to the RBCs making the hidden cytoskeletal proteins of the RBCs accessible for the circulating antibodies. Due to all the above mentioned reasons the antibodies recognizes them as non-self and elicit an immune response (3). There are several other causes which may lead to AIHA other than due to a primary infections. For example higher incidence of occurance of AIHA after allogenic hematopoetic stem cell transplantation in adult patients. Further studies proved that the chances of development of AIHA is more in patients with HSCT from unrelated donors and also that they develop chronic extensive graft versus host disease (GVDH). In such cases it was observed that AIHA was never the primary cause of death, rather it was due to infection of GVDH (5). In some rare cases, liver transplantation or solid organ transplantation leads to the development of AIHA (11)(14)(15). DIAGNOSIS: The destruction or removal of red blood cells from the circulation before their normal life span of 120 days is called Hemolysis. Hemolysis manifests itself as acute or chronic anemia, reticulocytosis or jaundice. Intravascular hemolysis refers to the destruction of red blood cells in the blood with the release of contents into plasma. This is then followed by direct membrane degradation and cell destruction caused by mechanical trauma from a damaged endothelium, complement fixation and activation on the cell surface. On the other hand, extravascular hemolysis refers to the removal and destruction of red blood cells with membrane alterations by the macrophages of the spleen and liver. The hemolysis can be categorized broadly into the following types: HEMOLYTIC ANEMIA HEREDITARY (6) ACQUIRED (6) ( Due to infections (6) Microangiopathic (6) Autoimmune (6) Autoimmune (6) Alloimmune (6) Drug induced (2) (6) Paroxysmal (1)(2)(6) Mixed (1)(2)(3) (4)(6) Cold (1)(2) (3)(6) Warm (1)(2) (3)(6) Immune complex or Auto-antibody (6) Drug absorption (hapten induced) (6) Delayed transfusion reaction (6) Acute transfusion reaction (6) Flow chart 2: Broad classification of autoimmune hemolytic anemia. Since all the above said categories of hemolytic anemias have many similar symptoms and expressions, efficient diagnostic techniques should be developed to detect the correct category of hemolytic anemia for its appropriate treatment. DIAGNOSTIC TESTING Basic diagnosis for hemolysis on the basis of laboratory and peripheral smear findings: Hematologic tests Reticulocytosis which is the normal response of the bone marrow to the peripheral loss of blood cells is an important characteristic laboratory feature of hemolysis. Checking for the presence of reticulocytosis can be used for diagnosis of hemolysis. Review of the peripheral blood smear with an assessment for pathognomic red blood cell morphologies (spherocytes or schistocytes) along with examination of WBCs and platelets is very important for the evaluation of any anemia (6). Chemistry tests Increased unconjugated bilirubin, increased lactate dehydrogenase, and decreased haptoglobin levels are characteristic feature of the distruction of RBCs and thus can be used for diagnosis of hemolysis (6). c) In addition to the above tests, urinary tests are also be performed (6) After diagnosis of the basic hemolysis, its etiology is determined by performing further diagnostic tests. This review article focuses on the diagnostic techniques specific for AIHA. Microspherocyte on a peripheral smear and positive direct antiglobin test (DAT) is a characteristic feature of AIHA (1). The direct antiglobin test ,is also known as direct Coombs test (8). It demonstrates the presence of antibodies or complement on the surface of red blood cells which is the hallmark of autoimmune hemolysis (8). In this technique, the patients red blood cells are mixed with rabbit or mouse antibodies against human IgG or C3. The test would give a positive result if an agglutination reaction between the patients antibody or complement coated red blood cells by anti-IgG or C3 is observed. RBC agglutination with anti-IgG serum indicates warm AIHA and RBC agglutination with anti-C3 indicates the cold AIHA. However further efficient and very specific diagnostic techniques should be developed to distinguish mixed AIHA and paraxysomal cold hemoglobinuria from the other types. Also the present diagnostic techniques many a times failed to give an errorless distinction between these two types of AIHA (4). The three types of drug induced anemia based on their mechanism of their mechanism of action can be detected by a positive DAT and its type can be identified by the intravascular or extra-vascular hemolysis that it produces (6). TREATMENT: Treatment mainly depends upon the type of AIHA i.e warm antibody type, cold antibody type, mixed antibody type or paraxysomal cold hemoglobinuria and also on the secondary or the idiopathic forms. The following are the treatment options for AIHA. However each treatment stratergies has its own advantages and disadvavtages. Warm antibody autoimmune hemolytic anemia i) CORTICOSTEROIDS The initial therapeutic agent used for treatment of WAIHA patients are the corticosteroids. There is a rapid onset of response. This therapy is usually maintained for 1-3 weeks, however sudden ceasation of therapy may result in prompt relapse of hemolysis. The adverse effects of long term use of corticosteroids as a therapeutic agent would include pulmonary aspergellosis, central nervous system hemorrhage (2), osteoporosis, avascular necrosis, susceptibility to infection, abnormalities in glucose and lipid metabolism and growth suppression in children (7).The gluocorticoids may inhibit antimicrobial activity of macrophages thus showing side effects when treated with it (2). In cases of pediatric anemia, prednisolone along with folic acid supplementation was used for therapy which showed a positive response in 81% of the patients (8). ii) SPLENECTOMY Splenectomy is mainly considered in patients who donot respond to the corticosteroid therapy. The main advantage of splenectomy is that it has a potential for a complete and long term remission. The adverse effect of spelectomy would include overwhelming postspelectomy infection (OPSI) which may result in serious morbity or mortality in a small percentage of patients after spelectomy (2)(7)(8). iii) IMMUNOSUPPRESSIVE DRUGS This is the third therapeutic option after both corticosteroid therapy and spelectomy. Examples of the immuno-suppressive drugs would include azathioprine, cyclosporine (8), rituximab (9)(11) etc. iv) DANAZOLE It is an attenuated androgen with good responses and comparatively lesser side effects (2)(7). v) INTRAVENOUS IMMUNOGLOBIN In patients who doesnot respond to the corticosteroids, it is used as a second line therapy. However, intravenous immunotherapy is expensive (2)(7). vi) PLASMA EXCHANGE Used for acute reversal of severe hemolysis along with other therapeutic agents. Cold antibody autoimmune hemolytic anemia The simplest and the possible way for reducing the severity of CAIHA is avoidance of cold. Plasma exchange showed a temporary benefit in a small percentage of patients. Any other therapeutic options involved more potential risks than probable benefits. Paroxysmal cold hemoglobinuria In most of the cases hemolysis terminates spontaneously and hence only supportive care is required. Sometimes transfusion of RBCs and corticosteroid therapy may have a positive impact on the treatment. Atmost care should be taken in case of secondary autoimmune hemolytic anemia i.e the underlying diseases like chronic lymphocytic leukemia, systemic lupus erytromatous, lymphomas etc should be treated for complete remission from AIHA (7).Combinational therapy was used in some cases of AIHA as secondary infection. Example, a case in which AIHA was found in association with Plasmodium vivax infection was treated with chloroquine and primaquine (for P.vivax infection), prednisolone and transfusion of least incompatible RBCs (for AIHA) (12). CONLUSION This review article gives a very short explanation about autoimmunity as a disorder. It mainly focused on auto-immune hemolytic anemia which is a subset of autoimmunity. The types of AIHA, causes, diagnosis and possible treatment stratergies were discussed. The future area of research under this topic is in finding out more efficient and specific diagnostic techniques to detect mixed and paroxysmal cold hemoglobinuria and treatment options with maximum results and minimum side-effects. Drugs like Bortizomib (13), Alemtuzumab (humanized monoclonal antibody targeting CD52 antigen) etc are still under research for the treatment of hemolytic anemia (16).

Scarlet Critique Essay -- essays research papers fc

The Scarlet Letter by Nathaniel Hawthorne was written in 1850. It was based on the Puritans of the 1600's, which were revived in Hawthorne's era. Hawthorne descended from Puritan heritage and harbored a sense of guilt and hatred for their way of life. He used many themes and literary techniques in The Scarlet Letter including symbolism and irony. He emphasized the individual's role in the community and the role of women in society. Hawthorne used romanticism as opposed to the classical correctness of writing. Romanticism was an artistic and intellectual movement that originated in the 18th Century and stressed strong emotion and imagination. Puritanism was the belief that all humans are sinful and that it is only though God and the bible that one can find redemption. Hawthorne did not agree with their philosophy. "The tendency of that Hawthorne had for calling unpleasant things 'Puritanic' is an indication that he rejected Puritanism†¦" (Gerber, p.41) He felt they were hypocrites and protrayed them as stuffy and disillusioned. They lived their lives atoning or sins they were born with. Ironically, Hawthorne's writings seemed just that- atonement for his would-be sin, the puritan heritage that he was born with. Even thought The Scarlet Letter set in 1642 in New England, it was written in 1850 at the revival of Puritanism. It focused the role of women in society. Hawthorne had a strong love for women and never portrayed them weak...

Confucius Goes on and on About ‘Humanity’ Essay

‘Humanity’ and ‘filial piety’ are probably the most important believes that Confucius had; he uses these two words more than any other words in ‘The Analects of Confucius’. Among many other things Confucius had mentioned, ‘humanity’ is the central thought of Confucianism that Confucius had believed everything starts from the ‘humanity’. ‘Humanity’ in a Chinese character means a combination of human and number two, which means how you should treat others when there are two or more people. It can be a relationship between husband and wife, sisters, brothers, and friends. Confucius basically wanted people to treat others with a love and treat others like you want others to treat you. Although, the most important thing is how you treat your parents. Confucius points out the importance of ‘filial piety’ by saying the root of ‘humanity’ is ‘filial piety’. â€Å"A man who respects his parents and his elders would hardly be inclined to defy his superiors. To respect parents and elders is the root of humanity†. (1. 2) In Confucianism, ‘filial piety’ is a fundamental moral standard and furthermore the most important teaching from Confucius. However, the definition of ‘filial piety’ is not just how you take care of your parents such as feeding them but you have to show your parents a respect and also show them a good attitudes. (2. 7, 2. 8) To practice ‘filial piety’ towards one’s parent s, you also do not want to give any anxiety to your parents. It also means that you do not want to harm your body even including your hair (this is why people at the time did not cut their hairs for their whole life) because your body is what your parents had given to you. ‘Filial piety’ is not only important when parents are alive but also important after their parents had passed away that they have to do the memorial ceremony for their ancestors with a respect like ancestors are still alive. Confucius mentions about the elders whenever he mentions about ‘Filial piety’, he believes that you do not only show respect to your parents but also to other people who are at your parents’ age. As grown up in the culture where there are still many elderly people believe in Confucianism, showing respect to people who are older than you is important especially to people who are at your parents’ age because they are also someone’s parents and you want your parents to treated as you treat others’ parents. In conclusion, ‘humanity’ is the central thought of Confucianism. ‘Filial piety’ is what Confucius had thought most important factor of ‘humanity’. ‘Filial piety means how you show a respect to your parents but it also indicates how you respect your leaders and show an honor to your country. Confucius points out ‘filial piety’ is a fundamental of love others, respecting your leaders and show an honor to your country, so basically Confucius had though ‘filial piety’ is the root of ‘humanity’.

Understanding Sexual Dimorphism

Understanding Sexual Dimorphism Sexual dimorphism is the difference in morphology between male and female members of the same species. Sexual dimorphism includes differences in size, coloration, or body structure between the sexes. For example, the male northern cardinal has a bright red plumage while the female has a duller plumage. Male lions  have a mane, female lions do not. Examples of Sexual Dimorphism Male elk (Cervus canadensis) grow antlers, while female elk do not have antlers.Male elephant seals (Mirounga sp.) develop an elongated snout and fleshy nose that they inflate as a sign of aggression when competing with other males during the mating season.Male birds of paradise (Paradisaeidae) are noted for their elaborate plumage and complex mating dances. Females are far less ornate. In most cases, when size differences exist between the male and female of a species, it is the male that is the larger of the two sexes. But in a few species, such as birds of prey and owls, the female is the larger of the sexes and such a size difference is referred to as reverse sexual dimorphism. One rather extreme case of reverse sexual dimorphism exists in a species of deepwater anglerfish called the triplewart seadevils (Cryptopsaras couesii). The female triplewart seadevil grows much larger than the male and develops the characteristic illicium that serves as a lure to prey. The male, about one-tenth the size of the female, attaches itself to the female as a parasite. Resources and Further Reading Folkens P. 2002.
