Red Scarf Girl Essay Example | Topics and Well Written Essays - 500 words

Red Scarf Girl - Essay Example He is a focused academic achiever who is at the verge of embracing the culture revolution. In one instance, this main victim did wear a red scarf, carrying around a red book that proposed the support of revolution acts. She was a good supporter and campaigner of the revolution occurring in China. In another instance, she is shocked at the boy who insists that the father be a part of the four odds inclusive of the old ideas, the old culture, the old habits and old habits. Thinks became worse than before, and they fell victims of persecution. She starts to speak of a wealthy neighbor whom she finds at the verge of being thrown outside the house. She was then supposed to sweep the streets of the town in the presence of the all the people. The sweeping did occur in the front of the old mansion. In the short story, â€Å"She did keep her eyes on her work. She could be seen moving her broom up and down. At long last, she happened to tripped over the broom and fell down.†(Jiang, pg. 22) In another instance, the author states that she is respected in school and did hold a leadership position. However, the aspects of culture had very strong revolutions in the school. She is shocked that the teachers were being changed, and replacements done to favor those who were teaching different ways. In addition to that, the degree of acceptance in schools was not determined by good academic achievements of good grades that the students got. Even the poor students who did not have good achievement in the studies have an equal opportunity in having acceptance in those schools. This is in contrast with the original trend where the students were enrolled based on lotteries. Such a system was in place to ensure that there was no favoring that was in the system (Jiang, pg. 35). Ji li also faces another shocking scenario, where she undergoes family exposure and their family is attacked, and properties taken away. His father

The European Enlightenment Essay Example for Free

The European Enlightenment Essay The scientific revolution is more of a new or modern way of thinking about nature. While science already had a presence prior to the 16th century, the teachings were based more on practical applications, rational thought and magic. s of science, 3elements permeated it – empirical practice, magic and rational thought which continued for thousands of years until the 16th and 17th century. With the scientific revolution, rational thought was enhanced through methods which can be the sole explanation for any phenomena of nature. Refute with reason but overwhelm by experiment. (Hall xvi). We think of Galileo as the first of the moderns because he broke the strangling hold of the traditional authorities – Aristotle, Ptolemy and Galen – upon scientific thought. He supported the Copernican hypothesis. He boldly countered errors of traditionally accepted beliefs and appealed to something new through the evidence of experiments. His system was enhanced by philosophers such as Francis Bacon and Rene Descartes who called their subject natural philosophy in an attempt to give a systematic explanation to the natural. With the entry of Sir Isaac Newton and the â€Å"invisible colleges†, discoveries and inventions came one after the other. Whereas religion used deductive reasoning in the arrival of its conclusions, the revolution brought on inductive reasoning which begins with a hypothesis that were tested using quantifiable data and methodical experimentation. By 1690, science had developed a philosophy – experimental and a method – mathematical and a goal – the improvement of the lot of mankind. (Baker ix, x). There came a paradigm shift in how the physical world was investigated. Reason slowly robbed magic of its power as it is an element of the irrational. Reason is initially used but compounded by experiment. The widely-believed Ptolemy system was anthropocentric based with an immobile earth is the center of the universe. While it was being discarded through deductive reasoning, i. e. , the world is vile and corrupt and therefore not worthy to be the center, the rational thinkers using the Copernicus hypothesis as reference and with observed facts and physical using reason, terrestrial mechanical phenomena, qualitative observation and quantitative observation by recalculating orbits went on to prove their heliocentric theory that the earth is only one of several planets that revolve around the sun. It also killed the Greek animism of appetites, natural tendencies, sympathies and attractions. Instead, explanation must be in terms of description of processes, mechanisms, interconnection of parts (Hall xvi, xviii). For Aristotle and his followers, bodies continually move so as to fulfill their natures. All matter is goal-oriented. They are of a teleological nature, which makes them animistic as they attributed soul-like properties. Modern natural philosophy used the machine metaphor, i. . the inner workings of a being are like the mechanism of a clock. They refer to their practice as mechanical philosophy. The development of mechanism gave rise to the view of matter-as-passive and is central to mechanical natural philosophy (Shapin 24-44). Traditional philosophies had been integrated into the teachings of the Roman Catholic Church which was the only Christian religion at that time. The Copernican theory was said to be contrary to the Holy Scripture and utterly heretical. It ran contrary to a decree in 1616 which was issued after the burning of Giordano Bruno for teaching the plurality of worlds or universes outside our own. As well, the present academe were slow in accepting that they have given their lives blindly to the defense of errors. The attitude in the middle ages was that where reason was incompetent to decide, faith should pronounce and that in many instances faith must prevail over reason. (Hall 74-75, 103-105). The medieval church had originally set its feet against and systematic scientific enquiry on the grounds that man was not intended to know the mind of God as interpreted by himself. Even Protestants stressed that all knowledge must come form the Bible. Bacon popularized that God actually intended man to recover its mastery over nature. In his text Instauratio Maga (The Great Instauration), the Book of Daniel was quoted in its cover, â€Å"Many shall pass to and fro and science shall be increased† (Shapiro 120). Thus, scientific enquiry became legitimate and prepared the way for scientific revolution. Later, there came about a new religious fervor in Deism, a name for the rationalized faith leading to the worship of the â€Å"divine clockmaker† which distrust anything mystical. It is based on the reasoning that if the universe was created by God, and the universe is a rational place then God was rational. (Baker x). Sir Isaac Newton in 1687 presented fundamental arguments of the mechanical universe in his book Principia Mathematia which basically summarizes the conceptual change brought about by the scientific revolution and the path it would take: mathematical models are accurate descriptions of the universe the universe moves rationally and predictably one need not appeal to revealed religion or theology to explain any aspect of physical phenomena\all planets and other objects move due to a physical attraction called gravity The universe concept is based on Inertia: every object remains at rest until moved by another object and stays in motion unless stopped or redirected by another object (Hooker).

Extra-Terrestrial Existence :: essays research papers fc

Has intelligent extra-terrestrial life visited the Earth? Have people actually seen spacecraft from another world? Have these spacecraft abducted human beings and performed experiments on them? Have these spacecraft been recovered by our goverment? Many believe this to be very true. Contrary to these beliefs, there is no physical or any evidence to prove these aliens have visited the Earth. But that does not rule out the existence of intelligent life elsewere in the Universe. There could always be life out there. But way to far away to have visited the Earth. The major reason people believe in aliens is a good reason to believe. This major reason is the sighting of a UFO. UFOs have revolutionized the way people think about aliens. The term UFO means: Unidentified Flying Object. Today the term UFO usually is reffered to an alien spacecraft. These alien â€Å"spacecraft† come in many shapes and sizes. The most common UFO has a disk or saucer shape. They move at very high speeds and appear to spin on an axis. UFO sightings vary from person to person. there have been so many reports of UFO sightings they can’t be counted. But are these sightings really alien spacecraft? The earliest sighting of a UFO is dated back to 213 B.C. Theses sighting were thought to be alien craft. Studies show that these sightings could have been a comet of a meteor. Around 742-814 A. D. "During the reign of Charlemagne, spacecraft took away some of the earth's inhabitants to show them something of the way of life of space people. These events are described in the Comte de Gabalis' Discourses.† Trench 1966. The University of Colorado conducted a UFO report. This elaborate report was lead by Edward U. Condon. Condon states, The decision to etablish this report for the Scientific Study of Unidentified Flying Objects stems from recommendations in a report dated March 1966 of an Ad Hoc Commitee of the Air Force Scientific advisory board set up under the chairmanship of Dr. Brian O’Brien to review the work of Project Blue Book. In this report Condon gives examples of some UFO reports. In 1952, so many UFO reports came in it clogged some Military communication channels. It was believed that an enemy planning a sneak attack could report a bunch of UFO reports to cause mass confusion to the Military communcations. Since 1953 many results of UFO study have been unclassified except when reasons needed to withold evidence because of classified missles or classified radar.

Separation Or Assimilation? :: essays research papers

Separation or Assimilation? Our country, The United States of America, was essentially founded on the principles of life, liberty, and the pursuit of happiness through solidarity of human kind. In Bernard R. Boxill's article, "Separation or Assimilation," he fundamentally poses the Hamletesque question: to assimilate or not to assimilate. Subsequent to the dilemma of some black cultural nationalists, whom not only argue for assimilation of the black American populace, but also believe that this assimilation into white culture is inevitable, against cultural pluralism. Cultural pluralism, which was initialized by W. E.B. Dubois in the late 19th century, is founded upon the peculiarities of races, living harmoniously in one nation-state, and lacking superiority or inferiority. Consequently to posing this question one dictates that there exist certain boundaries between cultures in our American society. Where do these boundaries come from and are they indeed necessary? Is integration of these cultures indeed inevitable? The goal of cultural pluralism as stated by Boxill are to establish pride in one's own race, to maintain the authenticity of one's own culture, and finally to benefit the world populace. Through pride, the disdain of inferiorities along with self respect, one adopts an attitude of self- segregation. Boxill argues for pride as a means of preserving one's race, overemphasizing differences between individuals because of the color of their skin or cultural differences, is a great defense to assimilation. Understanding Dubois's concept of cultural authenticity is to delve into the mysteries of self-actualization, that is to realize one's own potential. He asks himself, as an African American, whether his true identity lies in the jungles of Africa or in this land of America. He is of the opinion that these are his only two options. He concludes that his true identity goes beyond his American birth, citizenship, political ideals, language, laws, and religion; deep into the heart of Africa where a timeless culture was born and should be preserved for its beauty and used to benefit the world populace. "...the Negro people, as a race, have a contribution to make..."(Dubois,p244) The "Negro people" as a race, have certainly had a peculiar world condition throughout time and have had the ability to lend privileged insights into the human condition. The whole of humanity consists of many parts. From the cultural pluralist perspective, this whole can be benefitted most by the contribution of gifts from each race of humanity. But does not true diversity exist in individual persons rather than in large groups of unique individuals. It would seem obvious that the greatest degree of solidarity of humanity can be achieved

Social Learning Theory Psychology

In the field of Psychology, learning theories are there to attempt to explain how people think and what factors ultimately influence their behavior (ETR, 2007). There are various types of learning theories which all include different concepts and approaches to distinguish an understanding of human behavior and thought (ETR, 2007). The social learning theory (SLT) is just one of many theories which fall under the category of learning theories.The social learning theory, which is also commonly known as social cognitive theory, is justified in the belief that human behavior is determined by a triangular effect relationship between environmental influences, cognitive factors, and behavior (ETR, 2007). To have a proper understanding of the social learning theory, one needs to have been adequately briefed in the major contributors of the theory, a thorough description of what the theory entails, assumptions about the theory, and the developmental process and practice which has previously a nd currently taken place. Accomplishment is socially judged by ill defined criteria so that one has to rely on others to find out how one is doing (Kearsley, 2008). † This was stated by Albert Bandura, who is one of the two major contributors to the social learning theory. Bandura was born the youngest and only male of six siblings on December 4, 1925, in Mundare, Canada (Pajares, 2004). Fast-forwarding through his childhood, Bandura eventually found himself attending the University of British Columbia in Vancouver, Canada. His happening to fall into psychology was simply a fluke for him, for he was planning to get a degree in the biological sciences (Pajares, 2004). Bandura carpooled with peers to school who were all majors in engineering and pre-med, which entailed them to have early morning classes (Pajares, 2004). To fill his workload, Bandura had an open-morning spot to fill on his roster, which is where he fell into an introduction to psychology course (Pajares, 2004). He was instantly intrigued, which led him on his path to becoming one of the great contributors to this field. In 1949, he graduated with the Bolocan Award in psychology from the University of British Columbia (Pajares, 2004). His next task was to knock down graduate school, where he attended at the University of Iowa and received his Ph. D. in clinical psychology in 1952 (Pajares, 2004). Starting already in 1953, Bandura found himself teaching at Stanford University where he came across a well-educated student by the name of Richard Walters (Pajares, 2004). The two found themselves equally interested in the studies of explaining antisocial aggression in young males who came from wholesome households in upper-class residential areas in comparison to demonstrating that multiple opposing conditions may lead to behavioral problems (Pajares, 2004). This particular study led Bandura and Walters to co-write a book, Adolescent Aggression, in 1959 (Pajares, 2004). From there, Bandura wrote a chain of numerous books dealing with the social learning theory. Later he became a found member and elected President of the American Psychological Association in 1973 (Pajares, 2004). The second major contributor to the social learning theory came from a man by the name of Lev Vygotsky. Vygotsky was a Russian psychologist who was born in 1896 (Gallagher, 1999). Vygotsky was said to be a connoisseur of literature and philosophy (Gallagher, 1999). He attended the University of Moscow, where he studied and received a degree in law (Gallagher, 1999). It was not until 1924 when Vygotsky became interested in psychology (Gallagher, 1999). He had written a paper, The Psychology of Art, in 1925 which he used primarily in his thesis at the Moscow Institute of Psychology. Between the years of 1924-1934, before his death due to Tuberculosis, is when all his psychology work was practiced (Gallagher, 1999). In those 10 years of research and study of psychology, Vygotsky became an active follower of the sociocultural theory which suggests that development of a child relies on interaction with people and the tools or resources that the culture provides to help form their personal view of the world (Gallagher, 1999). The social learning theory (SLT), among others, is one of the most commonly used models currently. SLT is not a horribly complex model, for it is based around the interactions made from one another through observations, imitations, and modeling (Learning, 2008). Due to the fact that the SLT encompasses attention, memory, and motivation, it is said to be a bridge for psychologists between behaviorists and cognitive learning (Learning, 2008). The SLT focuses on the prospect that people learn through observing other people’s behaviors, attitudes, and outcomes of those behaviors observed (Learning, 2008). The social learning theory has three basic principles which make the breakdown of the theory very clear. The first principle is that people can learn through observation (Boeree, 2006). Bandura had conducted a well-known experiment known as the â€Å"Bobo Doll Study† (Boeree, 2006). In this study, Bandura had a set of dolls to which adult figures would interact with, in terms of gentle and/or aggressive behavior while children observed. Later, children were let into the room and were allowed to play with the same set of dolls that the adults had previously used. From observational learning, the children themselves inflicted the same type of behavior that the adults previously did. The children who observed a gentle act toward the Bobo doll reacted in the same way to pursue a more calm and loving affect toward the doll. In contrast, the children who observed aggressive behavior toward the Bobo doll also copied the same behavior of aggression toward the doll (Boeree, 2006). Bandura came up with three basic models of observational learning through conducting this study (Boeree, 2006). The first model is a live model. This involves an actual human individual who is acting out or demonstrating a particular behavior (Boeree, 2006). The second model is the verbal instructional approach. This involves giving the description and directions to acting out a certain behavior (Boeree, 2006). The third and last model is the symbolic model. This encompasses real of fictional characters. These characters are set to display behaviors in books, television, movies, or online media (Boeree, 2006). The second of the three basic principles is mental states are important to learning (Boeree, 2006). In greater detail, this involves and contributes to intrinsic reinforcement. Bandura was the contributor to this that previously noted that external, environmental reinforcement was not the only factor to influence learning and behavior (Boeree, 2006). This is where the idea of intrinsic reinforcement comes into place. This type of reinforcement is internal, which can include feelings of satisfaction, pride, and sense of accomplishment (Boeree, 2006). This is how the term of â€Å"social cognitive theory† correlates directly with the social learning theory. These types of reinforcements emphasize the internal thoughts and cognitions to help cooperate with theories of cognitive development (Boeree, 2006). The last of the three basic principles is that learning does not necessarily lead to change in behavior (Boeree, 2006). This means that observational learning does not define all observed behaviors; not all behaviors must be and are acting on (Boeree, 2006). One can learn something through observation without demonstrating the new information attained. These three main principles paved the way for more of Bandura’s work in the SLT, and the introduction to specific modeling process. The modeling process consists of four primary steps which lead to the development of understanding social learning theory. The first step is known by the word of â€Å"Attention† (Learning, 2008). This concept states that in order for an individual to learn, they have to be paying attention. It is possible for distractions of course, but anything that distracts one is going to ultimately have a negative effect on the observational learning taking place (Learning, 2008). A few examples of distractions could include being sleepy, groggy, sick, nervous, drugged, or even â€Å"hyper† in a sense can affect the learning process. All of those feelings can be competing factors with one’s attention span. Likewise, for something that may be of interest to the subject, full attention could be put into place and more dedication to observing and absorbing new information could happen (Learning, 2008). The second step is known as â€Å"Retention† (Learning, 2008). Retention is known as the storing process of observational learning. The ability or lack of to store or remember information plays an important role in the learning process (Learning, 2008). Retention, just like attention, can be affected by many different factors as well. This is also where imagery and language come into play. One is able to store information in terms of verbal knowledge or imagery knowledge, depending on the subject and situation. Later, one is expected to â€Å"bring up† the previously observed information if retention was successful (Learning, 2008). No need to say that retaining information is a vital aspect to observational learning. Third on the list of steps for the social learning model is â€Å"Reproduction† (Learning, 2008). This is where the performance of information retained is put into place. Once one has actually gone thorough attention and retained the proper information necessary, it is expected that one can perform the behavior initially learned (Learning, 2008). Of course, there are limitations to the ability of being able to perform certain tasks. For example, one can watch an Olympic gold medalist do an entire gymnastic tumbling routine on the mat, but may not have the ability to flex their body that particular way and be able to perform some of the stunts observed. This is why there is a leniency for the ability to perform tasks for the purpose that further practice may be needed (Learning, 2008). With a combination of practice of the learned behavior and continuous observation of the behavior, the performance level may have improvement and further skill advancement. The final of the four proper steps is â€Å"Motivation† (Learning, 2008). In order for most observational learning to be successful to any state, motivation is crucial to imitate the modeled behavior (Learning, 2008). There are several factors that Bandura stated to be a vital part in the motivational factor of the observed behavior performance. Reinforcement and punishment are key concepts in motivation levels (Learning, 2008). Past reinforcement, such as a reward after a proper outtake of the behavior, can motivate one to imitate the new observed behavior. In contrast, past punishment can be the same type of motivator. One who was punished previously for not conducting the observed behavior properly will make one want to conduct the new behavior successfully because they are aware of the consequences if not done properly (Learning, 2008). Also, promised reinforcements or punishments can do the same type of influence. A promised reinforcement, such as a treat, could make one strive to perform the task correctly. On the other hand, a promised punishment, such as a threat, can give the same affect (Learning, 2008).

Indespensable man essays

Indespensable man essays Our first president, George Washington, was indispensable for a number of reasons. In the book, Washington The Indispensable Man, James Thomas Flexnor points out many of the reasons he is indispensable, such as the fact that he never quit, he let his slaves go, he wouldnt side with the British or the French, and he didnt accept being president for the third term. These points may not seem to show his indispensability, but if Washington wasnt our first president who knows where we would be right now (probably be speaking French or in tyranny). Washington was criticized for a lot of things he did, and he was also thanked for everything later. When he would get criticized for something he wouldnt quit or give in to what they want because they criticized him. During the Jay treaty Thomas Paine insults Washington in a peroration saying, As to you, sir, treacherous in private friendship (for so you have been to me and that in the day of danger) and a hypocrite in public life, the world will be puzzled to decide whether you are an apostate or an impostor; whether you abandoned good principles or whether you had any. pg.354. Even when all odds are against him in criticism he wouldnt even be phased, and stand his ground. When Jefferson said, he got into one of those passions when he cannot command himself, ran on much on the personal abuse which had been bestowed on him, defied any man on earth to produce one single act of his since he had been in the government which was not done on the purest motives. pg.295. Washington said, he would rather be in his grave than be in his present situation. That he had rather be on his farm than to be made emperor of the world, and yet that they were charging him with wanting to be king. pg.295. The most indispensable accomplishment of Washington ...

Marijuana essays

Marijuana essays Marijuana, should it be legalized or remain a burning issue of controversy? Marijuana is a drug made from the dried leaves and flowering tops of the hemp plant (DuPont 189). Even though the cultivation, distribution, possession, and use of marijuana is illegal in many nations, including the United States and Canada, many people continue to use it on a daily basis (DuPont 195).Marijuana has been used as an intoxicant for thousands of years all around the world. Many people who use marijuana believe it improves their capabilities and talents, but scientists have failed to find any proof that this is true. There have been a number of studies that show that marijuana can damage short- term memory (Mendelson 24). Some of the physical short- term effects of marijuana include redness in the eyes and a rapid heartbeat. The drug also interferes with a persons judgment and coordination (DuPont 196). Marijuana usually makes users have feelings of panic, dread, dreamful, or quite simply, relaxed. These feelings will change due to the THC in the drug. When used as an intoxicant; the drug distorts the perception of time and distance. It can also impair a persons ability to drive an automobile or operate machinery. Marijuana may also cause users to feel like their sound, color, scent, taste, and touch seem intensified (Mendelson 25). According to a 1988 government survey, marijuana is the third most widely used drug in the United States, after cigarettes (Mendelson 27). Along with the short- term effects that marijuana has on people, there are also many long- term effects as well. Marijuana has many long- terms psychological and physical effects on users. These effects include causing the users to lose interest in school, their jobs, and social activities. Smoking Marijuana can give you bronchitis, chronic coughing, chest pains, and for males the reduction of sperm cells (DuPont 207). There have been many studi...

Effects of Economics, Race and Class on Social Standing essays

Effects of Economics, Race and Class on Social Standing essays One of the great things about America is that we are supposed to have a class-less society. Some countries have a class structure that is impossible to break. If you are born poor, you will die poor. There is no hope to break the cycle. That should not be the case in America. We like to believe that anyone can find fame and fortune in this country. The promise is that you can work hard and make it big. With this egalitarian outlook, America sounds like a great place to live. The theory is that we are all equal, and have an equal chance of achieving the American Dream. The Dream itself has many definitions, but for my purpose, I am going to assume it means that we can be upwardly mobile concerning social standing. Americans can be born poor and die rich. Of course, there are many subtle levels in between. That is where we will find popular culture. You see, although we have a class-less society, that does not mean we are totally without classes in our country. It really means we are able to transcend those classes and move up or down. We most certainly do have classes amongst ourselves. Primarily, our class is designated by what material possessions we have at this given moment. Not even what we own or how much money we have. It is the perception of affluence, not the accumulation of wealth, which most Americans value. In America, how others perceive you is what determines your social standing. Popular culture is out there for the masses. It is to give the lower and middle class people something to strive for. It tells us that, to be successful, we must drive a car costing more than the average annual salary of most Americans. It tells us what clothes to wear, what music we should listen to or where to live. It is through popular culture that our economy is driven. If it were not for credit and leasing, most Americans would never own a home or have a car to drive. This vici...

Modern Tourism Industry and its Impact on the Places Visited Term Paper

Modern Tourism Industry and its Impact on the Places Visited - Term Paper Example However, the benefits to the environment cannot be ignored in the sense that the idea of landscaping beautifies the environment and attracts more tourists’ to the lovely environment created. The issue of draining swamps near touristic developments has proven beneficial to the local inhabitants. Lastly, we consider how tourism affects the culture of an area. Many are the times that tourism development has been shown to lead to the erosion of the cultural identity of an area. However, the main aim of a touristic travel is not to erode the culture of an area but rather many tourist travels to experience the culture of the community that they visit. With these in mind, it is, therefore, right to disagree with the argument that modern tourism is destroying the places visited, and these we shall closely examine and prove in the subsequent paragraphs as we examine the individual aspects that tourism has influenced. Tourism does affect the culture of a society both positively and negatively. Ding and Pigram observed that tourism might encourage the maintenance of culture and tradition (1995: 8). They further state that the maintenance of traditional ways and goods needed to be restored because that is what attracted tourists. The constant visits from tourists helped in boosting and maintenance of the local cultures. Tourism represents an interface of cultural exchange it does allow for the interaction between communities and visitors who travel to experience the local cultures of a given community. Tourism allows these visitors to learn about the different cultures of the world. It also allows the appreciation of the various cultural diversity of the society that they visit. Tourists also learn and appreciate the new perspectives on life and society.

I have learnt that organizations play a major role in addressing issues of nurses as well as influencing of health policy. Moreover, such body’s helps in addressing issues related to the society in terms of health. I have also realized that an individual cannot be able to further nursing goals as compared to a group. Hence, joining such entity can help in shaping and achieve nursing goals. On the other hand, I have noted that advocacy by nurse and such bodies are crucial in addressing the needs of the patients. This plays a significant role in the provision of quality care. Moreover, I have realized that various ethical issues arise as nurse work in various environments. Some of the ethical issues are likely to put one in a dilemma. Some of these issues may affect the performance of the nurse. As a result, one has to learn of various initiatives that can help address such challenges. The other important thing I have learnt is the influence advocacy. I have realized that advocacy can play a significant role in the transformation of the nursing profession, society health and individual nurse.

Art as a Form of Creative Expression Essay Example | Topics and Well Written Essays - 750 words

Art as a Form of Creative Expression - Essay Example The most interesting thing about art is that it is culture-specific and it tells its own story from a certain cultural perspective. People belonging to different cultures use art to express themselves and it shapes their behavior. For instance, sculpture or paintings can be used to express the way of life of a group of people who share the same culture and values. In most cases, people who belong to a particular culture identify with a particular type of art. The same applies to music and dance. The type of music played by people belonging to different cultural groups varies from place to place since they have different cultures. In order to understand the culture of other people, this can be simply done through the consumption of their art products. The other important aspect about art is that it is a unique creation of something that depicts the lives of the people involved. Music, for example, is used to communicate different aspects of the life of a certain group of people. The m usic genre of people belonging to a certain group is shared by all members and it usually communicates important messages about the way of life of these people. Art can also be regarded as a form of entertainment in different sectors of society. Through music and dance, people are entertained while at the same time learning something very important about the way of life of a certain group of people.  Just like any other academic subject, it can be seen that art is learned and the courses offered to differ depending on the type of art being taught at a specific institution. Art lessons can be offered through different stages and individuals can choose the area of specialization from a lower level. There are also colleges and universities that offer various professional qualifications in art studies. Art is widely recognized as a professional qualification in different sectors of society. It is a source of livelihood for many artists who engage in creating different artifacts. As su ch, there are various measures that are put in place in different countries to protect the work of the artists so that they can enjoy the benefits of their creativity. Copyright laws are enforced in different countries so as to protect the products of the artists.

3 reflection questions Assignment Example | Topics and Well Written Essays - 250 words

3 reflection questions - Assignment Example The video enriched the coaching session between Ms. Wessling and her principal by enabling discussion and comparison of personal opinion and perspectives of what they have observed. Her principal emphasized that one of the advantages of using video in the classroom is for teachers to be self-reflective and to be open-minded to bring out what they have done to talk about it. Using video in practice can also be a way to improve our practice as it offers a certain degree of reality. There might be a difference between what is planned in the abstract of practice and the concrete of reality; thus, video exposes of what is intrinsically natural to teachers. I could record my own practice using three different means: (1) reflective journal, (2) voice recording, (3) video recording, and (4) used of evaluation tool. Just like Ms. Wessling’s rationale, the used of notes or reflective journal will help me to record concretely record my practice and permits expression of personal opinion and observation. The voice recording tool will help me analyze the modulation of my voice and how interesting my voice is to my students if I will be the listener. Sometimes, the manner or quality of teacher’s voice affects engagement of the students in the lesson and this voice quality cannot be best evaluated in a video. Thus, I will also use video recording to have a holistic view of the classroom – management, interaction, and mannerisms in teaching. Lastly, I added the used of evaluation tool in order to systematically and quantitatively support findings from other means of recording

Art as a Form of Creative Expression Essay Example | Topics and Well Written Essays - 750 words

Art as a Form of Creative Expression - Essay Example The most interesting thing about art is that it is culture-specific and it tells its own story from a certain cultural perspective. People belonging to different cultures use art to express themselves and it shapes their behavior. For instance, sculpture or paintings can be used to express the way of life of a group of people who share the same culture and values. In most cases, people who belong to a particular culture identify with a particular type of art. The same applies to music and dance. The type of music played by people belonging to different cultural groups varies from place to place since they have different cultures. In order to understand the culture of other people, this can be simply done through the consumption of their art products. The other important aspect about art is that it is a unique creation of something that depicts the lives of the people involved. Music, for example, is used to communicate different aspects of the life of a certain group of people.

The Film Industry Essay Example | Topics and Well Written Essays - 1000 words

The Film Industry - Essay Example Films have a very major core purpose that they all presume and that is creating entertainment (Aldikno, 1998). One of the major works in the film industry came in the early 1970s where a film known as Don't Look Now, directed by Nicholas Roeg was produced. The turn of events in the movie can be said to have led to the new generation of films. As such, it introduced the theme of murder as well as deaths. The last part of the film can be said to be sublime moving and further, a meditation on grief, which is frightening as well as relationships and beyond. For instance, Laura Baxter and John, who is her husband goes to enjoy their time together at Venice as a way of forgetting their daughter’s death (Rick 2001). The couple had indeed killed the daughter by drowning her. Two sisters, one of whom is blind and has capabilities of a psychic informs the couple that the little girl is still with them and this is manifested by the girl appearing in a red coat while wandering through the streets. With the reference to this episode of the film, the following discussion will aim at examining the earliest responses in regard to the film as a new medium and to pinpoint the potentials that would have been lost due to the responses. Moreover, the paper will aim at examining a film text that realizes the ideas that were set out from those criticism responses. When the theme of murder and deaths was introduced in the early films, many mixed responses concerning the theme arose. As such, the theme was not only a new concept but was also a new viewpoint and as such, it impacted mixed feelings among the audience. First, it tended to conflict the conceptions of the custom as well as some specific representations that were considered dynamic. In regard to this, the introduction of this new theme indeed was seen as changing the traditional view of the films (Catherine, 1992). These responses were therefore negative and many are the people who saw this notion of murder as going a gainst the set customs. In the early times, murder was a serious issue and by incorporating such scenes in a movie, some people, who followed the customary laws to the letter, felt that the films were disrespectful and going against the desired will of the society. They argued that people were likely to adopt such behaviors and as such, the society would develop a sense of insecurity. According to their perceived feelings, such movies did not portray the best of the pictures and hence had to be abominated (Catherine, 1992). On the other hand, some people received the theme of death and murder in films cordially as they saw it as an opportunity to take the film industry to a higher notch. When a film entails differentiated themes in its context, it assumes the shape of an abstract and as such, they provoke a certain organized association. In a film, a theme can be used but not at all times make a film successful. This is usually dependent on the feelings of the people towards it. How ever, if the theme is materialized, then the impression of the employed theme tends to be associative and as such, it becomes accepted by the audience. It is essential that the films, while incorporating the murder theme, to ensure that the plot of the film is designed in such a way that it have the capabilities of inferring something to the audience. In the same line of thinking, such an effort would indeed give rise to the most interesting and acceptable feelings in regard to the

The development of the printing press Essay Example for Free

The development of the printing press Essay The Reformation started in 1517, when Martin Luther began his protests against indulgences and then against the Roman Catholic Church. It was a time of immense change within Europe. There were many causes that contributed towards the Reformation, such as, the printing press and the state of the Church and they are all of some significance. The first factor that contributed towards the Reformation was the development of the printing press. In the middle of the 15th century the printing press was invented and this had many effects. Access to knowledge had now been increased greatly. Books and pamphlets could now be printed and everyone could get their hands on this newly available information. Printing highlighted discrepancies and contradictions between what was really in the Bible and what the Church said was in the Bible. This led to more people coming away from the Church. There was also a decrease in censorship by the Church. The Church could no longer control knowledge and intellectual thought as they had once done before the development of the printing press, when the monks used to write all the books available, by hand and therefore, controlling what went into them. If it wasnt for the printing press, the new ideas which led to Reformation might never have got off the ground. Another contributing factor to the Reformation was the revival of classical texts. Ancient Greek and Roman texts were rediscovered and with them new ways of thinking. For example, the works of the Greek philosopher, Protagoras were recovered and in his works there was the idea that, man is the measure of all things, i.e. man is unlimited in potential. New ideas such as these led to Humanism- the study of arts, architecture, literature and language, which replaced the previous idea of Scholasticism. These new ideas led to people ideas and beliefs changing and this proved a great challenge to the Church. People were questioning the beliefs of the Church and if they were true or false. One of the biggest causes of the Reformation was perhaps the state of the Church. The medieval Church had many abuses; there were many ways in which  the Church had been diverted from its spiritual mission by its corruption of the world. There was simony, the raising of cash through the sale of posts in the Church hierarchy which led to pluralism- the holding of several offices and absenteeism- when clergymen acquired offices solely for their income rather than because they were going to undertake any of their duties. Powerful families could add Church offices to their other acquisitions. The Church was meant to be separate from the world through the rule of celibacy; however some priest went against this rule and wandered. A cardinal or bishop might have his courtesan (a high class prostitute) and an ordinary priest his concubine. Where a bishop got to know about a priest and his concubine, the routine was to exact a fine rather than to split them up. Criminals could claim benefit of clergy. Simple literacy was regarded as pretty good evidence, would be tried before a Church court and guaranteed a light penalty, even for so serious a crime as murder. Abuses such as these produced resentment amongst many of the laity, the mass of people without benefit of clergy. Church taxation provoked laymen more than anything else. The tithe, 10 percent of all produce, had to be paid over to support the Church and there were many other taxes as well, such as Peters pence, a tax on hearths paid to the Pope. The German people despised the fact that their money went to Rome and didnt do anything for them. Convents were shamefully lax and that was because they were useful as dumping grounds for the excess daughters of well-to-do families. Relics of saints, which pilgrims traveled to see and to touch and to pay for the privilege, were often frauds. The forearm of St Andrew might just be a pigs bone, sceptical travelers noted enough nails from the Cross to make a forest of crosses and enough of the Virgins milk to launch ships. Indulgences, which were sold by the Church as though they were passports from the torments of purgatory directly into the bliss of Paradise, had  become crude money-raising devices but that was possible because there was so much ready demand for them. This state of the Church led to dissatisfaction within the people and when books with new ideas were printed, people were ready to read and accept them. Rulers and kings helped the Reformation to come about as they failed to put the movement down. The Reformation would provide opportunities for princes, as they could take over churches in their own country and rule them themselves. There were increasing differences between the rulers and the Pope and they wanted to oppose the Pope and let the Reformation gather pace. If the princes hadnt have sat back and let the Reformation take place, it might not have taken place as they would have had enough power to prevent the ideas from spreading and gaining support. The printing press was a major factor towards the Reformation, however it wasnt the most important, other factors contributed and together they helped bring the Reformation about. The other causes were very significant too. The state of the Church had led to growing resentment towards the Church and it was only a matter of time before this led to a major revolt against the Church. The bringing about of new ideas and humanism, led to new ideas and it would have eventually changed thinking at the time. The printing press helped in the spreading of the new ideas and ways of thinking that came with the Reformation, but these new ideas might have come about without the printing press, just at a later time.

Hereditary Spherocytosis: Review of the Genetic Disorder

Hereditary Spherocytosis: Review of the Genetic Disorder Ginamar Galvan Abstract This review is on the studies of several scientists whom completed research on the genetic disorder, spherocytosis. Based on several articles in the literature, it was learned that spherocytosis is an inherited anemia caused by the dysfunction of the cell’s cytoskeleton. These articles provide information of hereditary spherocytosis comprising of the disorder on the molecular level and how the patient’s diagnosis is concluded using laboratory testing. Patients can be found to be affected on a certain level ranging from mild to severe. They are then prescribed remedial medical attention pertaining to their level. The research showed that a form of response is to undergo a splenectomy which can ease a patient’s ailment, but has been found to not correct the life span of erythrocytes unlike speculation that it did. Hereditary Spherocytosis: A Review on the Genetic Disorder Introduction Hereditary spherocytosis is an anemic disorder affecting the blood that causes erythrocytes to be produced as spheres while normal erythrocytes are shaped as concave disks. The spheroidal shape is caused by a loss of membrane surface relative to intracellular volume (Gallagher 2005). Spherocytosis is genetically based, meaning that it can be passed down from either parent who already encompasses the disorder. This disorder can be found in all racial classifications but is more prevalent in Caucasians (Oliveira et.al 2012). Spherocytosis in Northern Europe and North America have a 1 in 5000 births in reported incidences and is usually the cause of inherited chronic hemolysis (Huq et al., 2010 and Bolton-Maggs et al., 2004). In the reviewed literature, spherocytosis has been researched and discussed regarding various aspects of this disorder, including the functionality of erythrocytes and what occurs after diagnosis. Cellular Level of Spherocytosis In 1871, hereditary spherocytosis was first explained and the first splenectomy was also performed shortly after (Bolton-Maggs et al., 2004). Between family members, the expression of spherocytosis is somewhat similar but the degree of severity differs throughout. The cause of the irregular shape and lifespan of the erythrocytes is the defect of an element in the cytoskeleton which is made of proteins in which the vertical attachment of the proteins to the lipid bilayer membrane is affected and therefore it is weakened (Bolton-Maggs et al., 2004). Other elements that influence the shape of the cell includes problems with spectrin, ankyrin, band 3 and/or protein 4.2 and the severity of the disorder is influenced by how many of these proteins are affected (Bolton-Maggs et al., 2004). Sodium dodecyl sulfate-polyacrylamide gel electrophorese is used as to determine whether or not these proteins have deficiencies. The defects in the genes of spherocytosis are present in five genes in chromosomes 1, 8, 14, 15 and 17 (Oliveira et al., 2012). Dysfunctions of these genes affect the membrane of the red blood cell which can threaten the cytoskeleton which is meant to maintain the form and elasticity of the cell. When the cytoskeleton is infringed upon, the red cell becomes abnormally shaped and does not live as long as a normal healthy cell (Oliveira et al., 2012). According to the article, â€Å"Guidelines for diagnosis and management of hereditary spherocytosis†, a hundred and seventy-four individuals were recruited from a hundr ed and twenty-three families and spectrin-deficient pro-bands were a larger cause than any other protein defect in patients when compared to parents who were seemingly regular. Diagnosis of Spherocytosis Hereditary spherocytosis is usually diagnosed when the patient is a child who has a varying extent of anemia, jaundice, and splenomegaly (Bolton-Maggs et al., 2004). Family history is also very important when diagnosing because in most cases seventy-five percent of patients will have a family history of the disorder (Gallagher 2010). There are different varieties at which hereditary spherocytosis affects people and treatments can sometimes require blood transfusions. Complications may develop which include severe anemia which may cause growth delay, deferred sexual maturation, tumors, and skin ulcers and many of these patients are transfusion dependent (Gallagher 2010). The patients that participated in the clinical study at the Pediatric Hematology Center of Hospital das Clà ­nicas, Universidade Federal de Minas Gerais in the journal, â€Å"Clinical course of 63 children with hereditary spherocytosis: a retrospective study†, were followed for about 19 years and had scheduled follow ups for every three months or in some cases more often if it was deemed necessary. They were diagnosed based upon their clinical history, physical examination and tests done in the laboratory and family histories were studied. Patients were classified as mild, moderate or severe depending on their hemoglobin concentration, bilirubin concentration and reticulocyte count and were also screened by ultrasonography to see if they had cholelithiasis. Splenectomy happened when there is an increase in the size of the organ and hemoglobin is decreased while reticulocyte count increased. Ones that needed a spleen sequestration were given immunizations and penicillin. When hemoglobin and reticulocyte count both decreased the patient was categorized to be in aplastic crisis. Most patients have somewhat balanced hemolysis accompanied by slight to average anemia. Anemia can be asymptomatic except for some fatigue and jaundice occurs in patients about half of the time which is usually in association with viral infections (Gallagher 2010). When some patients’ erythrocytes are stressed, patients may notice symptoms because their body is compensating with amplified erythropoiesis for their hemolysis (Gallagher 2010). In the journal, â€Å"Guidelines for diagnosis and management of hereditary spherocytosis†, several laboratory tests were used for diagnosis which includes osmotic fragility, acidified glycerol lysis test, osmotic gradient ektacytometry, and eosin-5-maleimide binding. Osmotic fragility is affected by elevated reticulocyte count while acidified glycerol lysis test detects autoimmune hemolytic anemia, hereditary persistence of fetal haemoglobin, pyruvate kinase and glucose-6-phosphate dehydrogenase deficiency as well as chronic renal failure. The osmotic gradient ektacytometry measures red cell deformability and the eosin-5-maleimide binding shows distinct histograms for red blood cells of spherocytosis. And in the journal, â€Å"Clinical course of 63 children with hereditary spherocytosis: a retrospective study†, the tests in the laboratory include the patient’s complete blood count, smear, reticulocyte count, concentration of bilirubin, positive osmotic fragility test and negative direct antiglobulin test. The osmotic fragility of the patients’ looked at the red blood cells in tubes that were washed in mixtures of increasing sodium chloride concentrations that were either put in incubation for 24 hours or not. Treatment of Spherocytosis There are ways to manage hereditary spherocytosis such as using folate therapy if the patient is severe, routine observation, frequent blood tests and in some cases splenectomy. Splenectomy can improve anemia in most patients including even the most severe. The splenectomy can be performed laproscopically and is the more preferred method because it causes less discomfort after the surgery, quicker recovery time, shorter hospitalization, and decreased costs. Splenectomy complications can occur including infection, bleeding and pancreatitis (Gallagher 2010). This operation used to be considered routine in hereditary spherocytosis patients but now is being reconsidered concerning the complications that can arise. The patients that usually receive a splenectomy are diagnosed to be severe or are older patients whose vital organs are inhibited vascularly (Gallagher 2010). Moderate patients possess more options and may not need a splenectomy. In â€Å"Clinical course of 63 children with hereditary spherocytosis: a retrospective study†, when patients were followed up, thirty-five patients needed transfusions and the need for them was more common in the severity group. Fourteen needed spleen sequestration, three had aplastic crisis, twenty-two had a splenectomy, seventeen developed cholelithiasis and ten had a cholecystectomy. Patients had different degrees of jaundice and anemia while most had some enlargement of the spleen. About 2/3 of the patients were anemic and seventy percent had splenomegaly. Patients that were classified as severe were younger and needed more blood transfusions than the other groups. A viral infection could lead to an overestimated severe classification because anemia level rises. All the patients were told and arranged to take folic acid. Does Splenetomy return Red Cell life span to normal? In some patients, anemia, reticulocytosis, and hyperbilirubinemia may disappear and cause some to infer that the patient no longer has problems with their red cell survival rate (Chapman 1968). Using a micro-hematocrit the hematocrit was determined, the reticulocytes were found in a methylene blue contained cover slip smear, and the red cell was counted by an electronic counter (Chapman 1968). The red cells that were being circulated were labeled with Diisopropyl fluorophosphates. DF32P were given to eleven patients that had a splenectomy two to twenty seven years before. The mean cellular hemoglobin content and concentration were higher in males than females. The concentration was of a normal degree in the females and above normal in all but one of the males (Chapman 1968). Mean red blood cell life spans were determined by the disappearance of radioactivity from the circulating blood by calculating linear regression. From the evidence the life span of the red blood cells seems to be somewhat dependent on age after their splenectomy. Patients that are within the same family do not show any consistency of the degree of spherocytosis expression. The red blood cell life span was averaged at about ninety-six days when normal life span is about one hundred twenty-three days (Chapman 1968). The range of life span between the patients ranged from seventy-six to one hundred eighteen days. From these results it is inferred that splenectomy does not repair red blood cell life span. Conclusion Hereditary spherocytosis is often identified in a patient’s childhood or early adult life, although, spherocytosis can be diagnosed at any age conditional to the entirety. This molecular disorder impacts their quality of life regarding aspects of treatment, finances, stress and recovery. As discoveries are made in this area of research, individuals will have a greater knowledge of spherocytosis and advancement in the treatment of this disorder including more options.

Chelation is the formation or presence of two or more separate bindings between a polydentate (multiple bonded) ligand and a single central atom. Usually these ligands are organic compounds, and are called chelants, chelators, chelating agents, or sequestering agents. The ligand forms a chelate complex with the substrate. Chelate complexes are contrasted with coordination complexes composed of monodentate ligands, which form only one bond with the central atom. The denticity of a central atom, of course, refers to the number of bonds formed by the central atom. Chelants, according to ASTM-A-380, are chemicals that form soluble, complex molecules with certain metal ions, inactivating the ions so that they cannot normally react with other elements or ions to produce precipitates or scale. The chelate effect. The chelate effect describes the enhanced affinity of chelating ligands for a metal ion compared to the affinity of a collection of similar nonchelating (monodentate) ligands for the same metal. Consider the two equilibria, in aqueous solution, between the copper(II) ion, Cu2+ and ethylenediamine (en) on the one hand and methylamine, MeNH2 on the other. Cu2+ + en [Cu(en)]2+ (1) Cu2+ + 2 MeNH2 [Cu(MeNH2)2]2+ (2) In (1) the bidentate ligand ethylene diamine forms a chelate complex with the copper ion. Chelation results in the formation of a five-membered ring. In (2) the bidentate ligand is replaced by two monodentate methylamine ligands of approximately the same donor power, meaning that the enthalpy of formation of Cu-N bonds is approximately the same in the two reactions. Under conditions of equal copper concentrations and when the concentration of methylamine is twice the concentration of ethylenediamine, the concentration of the complex (1) will be greater than the concentration of the complex (2). The effect increases with the number of chelate rings so the concentration of the EDTA complex, which has six chelate rings, is much much higher than a corresponding complex with two monodentate nitrogen donor ligands and four monodentate carboxylate ligands. Thus, the phenomenon of the chelate effect is a firmly established empirical fact. Cu2+ complexes with methylamine (left) and ethylenediamine (right) The thermodynamic approach to explaining the chelate effect considers the equilibrium constant for the reaction: the larger the equilibrium constant, the higher the concentration of the complex. Ethylene diamine tetra acetic acid, Widely abbreviated as EDTA is a polyamino carboxylic acid and a colourless, water-soluble solid. Its conjugate base is named ethylenediaminetetraacetate. It is widely used to dissolve scale. Its usefulness arises because of its role as a hexadentate (six-toothed) ligand and chelating agent, i.e. its ability to sequester metal ions such as Ca2+ and Fe3+. After being bound by EDTA, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA. EDTA is used to bind metal ions in chelation therapy, e.g., for mercury and lead poisoning. It is used in a similar manner to remove excess iron from the body. This therapy is used to treat the complication of repeated blood transfusions, as would be applied to treat thalassaemia. EDTA acts as a powerful antioxidant to prevent free radicals from injuring blood vessel walls. Dentists use EDTA solutions to remove inorganic debris (smear layer) and prepare root canals for obturation. It serves as a preservative (usually to enhance the action of another preservative such as benzalkonium chloride or thiomersal) in ocular preparations and eyedrops. In evaluating kidney function, the complex [Cr(edta)]- is administered intravenously and its filtration into the urine is monitored. This method is useful for evaluating glomerular filtration rate. EDTA is used extensively in the analysis of blood. It is an anticoagulant for blood samples for CBC/FBEs (complete blood count also known as full blood examination). Laboratory studies also suggest that EDTA chelation may prevent collection of platelets on the lining of the vessel [such as arteries] (which can otherwise lead to formation of blood clots, which itself is associated with atheromatous plaque formation or rupture, and thereby ultimately disrupts blood flow). These ideas are theoretical, and have so far been proven ineffective; however, a major clinical study of the effects of EDTA on coronary arteries is currently (2008) proceeding. EDTA played a role in the O.J. Simpson trial when the defense alleged that one of the blood samples collected from Simpsons estate was found to contain traces of the compound. In nature Virtually all biochemicals exhibit the ability to dissolve certain metal cations. Thus, proteins, polysaccharides, and polynucleic acids are excellent polydentate ligands for many metal ions. In addition to these adventitious chelators, several biomolecules are produced to specifically bind certain metals . Histidine, malate and phytochelatin are typical chelators used by plants. Histidine (abbreviated as His or H) is one of the 22 proteinogenic amino acids. In terms of nutrition, histidine is considered an essential amino acid in human infants. After reaching several years of age, humans begin to synthesize it, at which point it becomes a non-essential amino acid. Its codons are CAU and CAC. Histidine was first isolated by German physician Albrecht Kossel in 1896. Malic acid is an organic compound with the formula HO2CCH2CHOHCO2H. This carboxylic diacid is the active ingredient in many sour or tart foods. Malic acid is found mostly in unripe fruits. Malic acid has two stereoisomers, a left-handed L-enantiomer and a right-handed D-enantiomer, but only the L isomer exist naturally. The salts and esters of malic acid are known as malates. The malate anion is an intermediate in the citric acid cycle. Phytochelatins are oligomers of glutathione, produced by the enzyme phytochelatin synthase. They are found in plants, fungi, nematodes and all groups of algae including cyanobacteria. Phytochelatins act as chelators, and are important for heavy metal detoxification.They are abbreviated PC2 through PC11. A mutant Arabidopsis thaliana lacking phytochelatin synthase is very sensitive to cadmium, but it grows just as well as the wild-type plant at normal concentrations of zinc and copper, two essential metal ions, indicating that phytochelatin is only involved in resistance to metal poisoning. Phytochelatin seems to be transported into the vacuole of plants, so that the metal ions it carries are stored safely away from the proteins of the cytosol. In biochemistry and microbiology Virtually all metalloenzymes feature metals that are chelated, usually to peptides or cofactors and prosthetic groups. Such chelating agents include the porphyrin rings in hemoglobin and chlorophyll. Many microbial species produce water-soluble pigments that serve as chelating agents, termed siderophores. For example, species of Pseudomonas are known to secrete pycocyanin and pyoverdin that bind iron. Enterobactin, produced by E. coli, is the strongest chelating agent known. Porphyrins are a group of organic compounds of which many occur in nature. One of the best-known porphyrins is heme, the pigment in red blood cells. Heme is a cofactor of the protein hemoglobin. They are heterocyclic macrocycles composed of four modified pyrrole subunits interconnected at their ÃŽÂ ± carbon atoms via methine bridges (=CH-). Porphyrins are aromatic Hemoglobin (also spelled haemoglobin and abbreviated Hb or Hgb) is the iron-containing oxygen-transport metalloprotein in the red blood cells of vertebrates and the tissues of some invertebrates. Hemoglobin in the blood is what transports oxygen from the lungs or gills to the rest of the body (i.e. the tissues) where it releases the oxygen for cell use. In mammals the protein makes up about 97% of the red blood cells dry content, and around 35% of the total content (including water). Hemoglobin has an oxygen binding capacity between 1.36 and 1.37 ml O2 per gram of hemoglobin, which increases the total blood oxygen capacity seventyfold. Hemoglobin is involved in the transport of other gases: it carries some of the bodys respiratory carbon dioxide (about 10% of the total) as carbaminohemoglobin, in which CO2 is bound to the globin protein. The molecule also carries the important regulatory molecule nitric oxide bound to a globin protein thiol group, releasing it at the same time as oxygen. Heme group Chlorophyll (also chlorophyl) is a green pigment found in almost all plants, algae, and cyanobacteria. Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. However, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues. Chlorophyll was first isolated by Joseph Bienaimà © Caventou and Pierre Joseph Pelletier in 1817. In geology In earth science, chemical weathering is attributed to organic chelating agents, e.g. peptides and sugars, that extract metal ions from minerals and rocks. Most metal complexes in the environment and in nature are bound in some form of chelate ring, e.g. with a humic acid or a protein. Thus, metal chelates are relevant to the mobilization of metals in the soil, the uptake and the accumulation of metals into plants and micro-organisms. Selective chelation of heavy metals is relevant to bioremediation, e.g. removal of 137Cs from radioactive waste. Applications Chelators are used in chemical analysis, as water softeners, and are ingredients in many commercial products such as shampoos and food preservatives. Citric acid is used to soften water in soaps and laundry detergents. A common synthetic chelator is EDTA. Phosphonates are also well known chelating agents. Chelators are used in water treatment programs and specifically in steam engineering, e.g., boiler water treatment system: Chelant Water Treatment system. Heavy metal detoxification. Chelation therapy is the use of chelating agents to detoxify poisonous metal agents such as mercury, arsenic, and lead by converting them to a chemically inert form that can be excreted without further interaction with the body, and was approved by the U.S. Food and Drug Administration in 1991. In alternative medicine, chelation is used as a treatment for autism, though this practice is controversial due to no scientific plausibility, lack of FDA approval, and its potentially deadly side-effects. Though they can be beneficial in cases of heavy metal poisoning, chelating agents can also be dangerous. The U.S. CDC reports that use of disodium EDTA instead of calcium EDTA has resulted in fatalities due to hypocalcemia. Other medical applications Antibiotic drugs of the tetracycline family are chelators of Ca2+ and Mg2+ ions. EDTA is also used in root canal treatment as a way to irrigate the canal. EDTA softens the dentin facilitating access to the entire canal length and to remove the smear layer formed during instrumentation. Chelate complexes of gadolinium are often used as contrast agents in MRI scans. Copper-64 is a radioactive nuclide of copper which has unique decay properties making it useful in nuclear medicine for both imaging and therapy. 64Cu-ATSM (diacetyl-bis(N4-methylthiosemicarbazone)) has been shown to increase the survival time of tumor-bearing animals with no acute toxicity. Areas of low oxygen retention have been shown to be resistant to radiotherapy because hypoxia reduces the lethal effects of ionizing radiation. 64Cu was believed to kill these cells because of its unique decay properties. In this experiment, animal models having colorectal tumors with and without induced hypoxia were administered Cu-ATSM. Cu-ATSM is preferentially taken up by hypoxic cells over normoxic cells. The results demonstrated that this compound increased survival of the tumor bearing hamsters compared with controls. In the control groups, death due to tumor burden occurred within 4 weeks while animals with a dose greater than 6 mCi of the radioisotope tumor growth was inhibited and survival increased. The results also suggested that multiple doses and a single dose of 10 mCi were equally effective while the multiple dose regimen i s safer for non-target tissue. Radiotherapy of cancer cells using 64Cu can be applied in medical research and clinical practice. The advantages of radiotherapy with beta emitters of this energy are that there is enough to do substantial damage to the target cells but the mean range in tissue is less than a millimeter so non target tissues are unlikely to be harmed. In addition, 64Cu is a positron emitter making it a viable PET imaging radionuclide which can give real time images of the physiological processes in the system. These abilities in conjunction enable accurate monitoring of drug distribution and biokinetics simultaneously. Radiotherapeutic efficacy of Copper-64 depends highly upon the radioligand delivery to the target cells, so the development of bifunctional chelates is central to development of 64Cus potential as a radiopharmaceutical. With sufficient development, 64Cu is likely to become a central element in nuclear medicine in the years to come. A preliminary study of the bio availability of iron- and zinc-glycine chelates Groups of rats were fed diets containing marginal levels of Fe and Zn as glycine chelates (tradename Chelazome, Albion Laboratories, Verona, New Jersey, USA), or the same level of mineral as ferrous sulphate or zinc carbonate. The Fe diets were fed to weanling rats for 4 weeks and the Zn diets to young adult rats for 5 weeks. Blood Hb concentrations were significantly higher in the group fed Fe-chelazome than ferrous sulphate, 149 and 128 g/l respectively (P

The Utopian Solution in The Tempest Essay -- Tempest essays

  Ã‚  Ã‚   The entrance of The Tempest into theatres between 1610 and 1611, signifies a possible correlation between Shakespeare's play and the colonization of the ideal New World. Before analyzing the courtly order and utopian theme in The Tempest, it is important to understand the politics and culture of the court in the early 17th century. The society that Shakespeare emerges from plays an important role in the themes portrayed in The Tempest, because it leads to the utopian solution to the political and class conflict.   Ã‚  Ã‚   The definitions of politics and culture have changed drastically since the 17th century in Great Britain. The freedom of Americans to play an active role in politics and government greatly contrasts the role of the English during the time of The Tempest. Shakespeare lived in a time of government sovereignty, where the role of the people in politics was dependent upon their social (class) status. In "Political Culture," David Harris Sacks asserts that, "the 'sovereignty of state,' consisting solely in governmental powers, is understood to be a feature of a commonwealth, not the commonwealth as a whole" (Sacks 118-19). The lack of involvement of the majority of the commonwealth supports a problematic issue that the role of the people in government was dependent upon their social class, which presented an obvious inequality amongst the political system. The problems facing the commonwealth and the government lead to conformity and complacency amongst the people, but Shakesp eare had writing to overcome the ceiling on social class. Shakespeare's plays, specifically The Tempest, test the boundaries of politics and class order and tend to portray Shakespeare crossing from a conformist to a humanist.

Maturing In The Faith :: essays research papers

In the course of reading Chapter 1 of our book, I came across something that I have known all along but taken for granted, as though it was not more important than my upcoming doctor’s appointment. It is the simple yet breaking fact that I do not know what I believe in, or rather, I know what I believe, but I don’t exactly know why I believe. And I am not alone in my plight. Most Filipinos, unfortunately, are guilty of this folly. We all have faith in God, not because we know the Sacred Scriptures to the letter, not because we know and live the Word. We believe because, quite simply put, we were brought up in Catholic households, and educated in Catholic schools, and what sticks to our minds is that to be a good Christian, we must have faith in God. We get too extreme about it at times and take things too literally that we miss too many points. To be fair, our faith is “genuine';, as the book also said. We truly believe in God and we all try to live as good Catholics: mass every Sunday, rosary with the family every night, we go to confession and retreats, and we pray when we wake in the morning and before going to bed. But sadly, other than those “routine'; elements of being Christian, most of us do not really understand what the Bible says, or what the priests are preaching, or what really is the will of God. Neither do we involve ourselves with other people who are part of the Church. Not to mention, how we seem to think less of non-Catholics, instead of trying to share what we are all supposed to know, the Word of God. A friend told me about a conversation he had, the other person saying that non-Christians will never enter the kingdom of God. He was dead serious when he said this, which made me wonder if we, in fact, are better than the non-believers, or if we are any different at all. I can say with a clear conscience, because I believe it to be true, that I have faith in God. What I cannot reconcile myself with, is the undeniable fact that I lack insight into what I believe in. I will not be able to go out and tell another person about how the Spirit liberates me, because even as I know this, I do not completely understand it.

Natural Or Man Made Disasters Environmental Sciences Essay

With everything else being equal, the high sum of C dioxide in the ambiance which has changed the climatic conditions can increase growing of some nutrient harvests like rice, wheat and soya bean. But the addition in temperature can act upon the clip and quality of turning season and a batch of injury is caused to the harvests as a consequence of inundations and checkerss. This means that hereafter of nutrient production in many states is at a significant hazard. It depends on how expeditiously different states combat this job caused by planetary heating. ( Ranger & A ; Clark, 2012 ) The proposal below includes a nexus between the effects of planetary heating with the debut of genetically modified nutrient merchandises and additives as a counter to the job. Genetically modifying nutrient can help in heightening output of harvest workss to do them resistant to rapidly altering climatic alterations. They will assist the husbandmans grow nutrient economically and sustainably. ( â€Å" gram nutrient, † 2007 But more of import is the fact that there are certain jeopardies which are associated with these modified nutrient merchandises. These jeopardies and hazards must be eliminated to guarantee safe nutrient supply to people. Besides the multitudes should be educated about the benefits of these nutrient merchandises that helps them to do better determinations about their nutrient ingestion and protects them from the harmful effects of planetary heating. Different advertisement techniques like cusps, booklets and telecasting advertizements can help in this respect.IntroductionWith the rise in the degree of C dioxide in the ambiance and the subsequent planetary heating has led to an addition in temperature by 0.8 degree Celsius and is estimated to lift by 1.4 to 5.8 grade Celsius between the 21st century. This quandary will go on unless the emanation of green house gasses is halted. Among these gases carbon dioxide contributes the most towards the heating, an estimation of 60 % in the foll owing century. ( Hartman, Nippert, Orozco & A ; Springer, 2010 ) This addition in the atmospheric temperature and alteration in the form of rainfall with utmost conditions conditions like inundations, storms and checkerss is taking to infertile land for illustration in Southern Europe. The high degree of H2O and addition in temperature can besides ensue in H2O logging, plagues and diseases. ( Quested, Cook, Gorris & A ; Cole, 2010 )Consequence OF GLOBAL WARMING ON FOOD PRODUCTIONIn stead of the harm clime brings to agriculture it becomes apparent that harvest and nutrient production has a close nexus to planetary heating. Hence I agree to the claim that planetary heating effects the production and handling of nutrient in the developed states and undeveloped states because of combustion of fossil fuels through industrialisation. The alterations in clime influence the growing of plagues and microbic growing of macro environment. Hence it leads to biotic diseases imputing to fungi, bac teriums and viruses. Other abiotic facets like air pollutants influenced the production and wellness of workss. These factors besides affect the safety of nutrient. ( Jaykus, Woolridge, Frank, Miraglia, Gollop & A ; Tirado ) Furthermore apart from these direct effects, the indirect effects of climate lead to revenue enhancement or levy systems in all countries of nutrient production. This would supercharge the monetary value and handiness of different types of nutrient and influence the process of production that involves addition sum of emanation of green house gases. This will finally take to less ingestion of meat due to its increased monetary value. ( Quested, Cook, Gorris & A ; Cole, 2010 ) The clime alteration besides affects the nutrient fabrication and trade. Upcoming dangers in primary production can impact the working of the safety guaranting procedures needed to expeditiously restrict those dangers and maintain safety of the finished merchandise. Furthermore, the rise in mean temperature can increase the hazard to hygiene linked with storing and transporting nutrient merchandises. ( Jaykus, Woolridge, Frank, Miraglia, Gollop & A ; Tirado )GENETICALLY MODIFIED FOODIn order to accomplish benefits from Earthaa‚ ¬a„?s nutriment such nutrient has to be produced that bears the alteration in climatic conditions. The solution lies in genetically modifying nutrient and usage of additives and conserves. Genetically modified nutrient or harvests are the 1s that are produced through modern techniques in microbiology and the scientific discipline of agribusiness. They are made to better some traits that make them modified to peculiar topographic points and countries. There advantages are that they are immune to plagues and diseases ; hold more foods and can defy climatic alterations caused by planetary heating. There is an addition in the growing of these nutrient merchandises in United States since 1996. They include companies that invest in bring forthing nutrient that are immune to checkerss and inundations. ( Lundee, 2010 ) However, really few people are cognizant of the benefits of genetically modified nutrient and the additives. A survey was conducted in Korea in which it was found that consumers had really small consciousness about the safety methods attached with nutrient additives and they thought of them as harmful. So they avoided purchasing procedures nutrient incorporating additives. Hence it was found that consciousness amongst the people sing the benefits of modified nutrient merchandises and additives was necessary to avoid misinterpretations about them that were created chiefly by traditional media.ADVERSTINGaa‚ ¬a„?S ROLESo different advertisement techniques can be used to inform people about the alterations in clime through planetary heating and the how the nutrient job can be solved through familial alteration and additives. The survey in Korea suggested that in cusps, booklets and postings h ave a immense impact in conveying cognition to the consumers about the benefits of the preservatives and familial technology in guaranting nutrient safety. This advertisement technique was used during a study in Korea in which after exposing the audience with the postings they most of them agreed to utilize the additives and modified nutrient merchandises. They came to cognize that authorities has plan regulation bounds like ADIs for additives and preservatives to maintain consumers safe. ( Shim, Seo, Lee, Moonc, Kim & A ; Hee Park, 2011 ) . Such awareness runs should non merely be on a little graduated table but other manners of communicating like telecasting and newspapers can besides play an of import function in this respect. Creatively and sagely designed advertizements can act upon and learn multitudes to do the correct picks for their nutrient ingestion.ETHICAL ISSUESWhen new engineering like the genetically modified harvests is introduced there are certain ethical issues tha t come across. The inquiries arise if the engineering will guarantee general public assistance through enhanced safety of nutrient or does it brings injury for consumers and environment. Besides, if the engineering provides any deductions for the consumeraa‚ ¬a„?s rights like to inform the consumer sing what he is eating. Furthermore, has the engineering introduced deductions for the scientists for their freedom in making research in a manner that secures their personal award? Finally inquiries related to rule of justness may originate in such a manner as who will be profiting from the latest engineering and how will they counterbalance for those who are non profiting. ( Nuffield Council on Bioethics )CONCLUSION AND RECOMMENDATIONSWhen there are climatic alterations, certain things must be done to manage them instantly. These include safety steps for nutrient, theorizing procuring nutrient points, supplying clean nutrient and H2O, acknowledging and responding to climat ic alterations and nutrient borne diseases and educating multitudes about the safety of nutrient through runs. All this requires assorted trained groups who perform their occupation good, know about their responsibilities and have effectual squad coordination abilities. Proper planning has to be done to provide to these state of affairss by authorities and other sectors. These programs should pass on nutrient security hazards as the consequence of climatic alterations along the nutrient concatenation. This needs intersectoral analysis of countrywide infrastructural and treating ability to react to sudden alterations. ( Jaykus, Woolridge, Frank, Miraglia, Gollop & A ; Tirado ) The long term there is a demand to present new engineerings like genetically modified nutrient merchandises and additives can guarantee that safe nutrient supply is maintained. There is a demand to organize procedure and label nutrient points to help the consumer in keeping his healthy diet and forestalling fleshiness and diseases. Besides, sustainability of nutrient concatenation has to be maintained. ( Lazaridesa ) Last, consciousness is highly indispensable to be created amongst the multitudes about the latest engineering that is to be used in guaranting nutrient safety. This can be done through focal point groups, publicities, in-store signage, vouchers, client trueness cards and Internet consciousness. Furthermore, legal stairss have to be taken by authoritiess of several states to guarantee that the genetically modified nutrient and additives are free from chemicals that are harmful to human wellness. Merely in this manner we can battle the effects of planetary heating on the production of nutrient.

Measurements: Accuracy and Approximations

The need for accurate and precise measurements in today’s modern world cannot be understated.   Every discipline, from the physical sciences to the social sciences requires measurements that are both accurate and repeatable.   It must be accepted, though, that any measurement has inherent inaccuracies and imprecision and is indeed an approximation. Any measuring device has limited accuracy.   The inability to read the measurement beyond the smallest division shown on the device creates an approximation.   If the smallest division on a ruler is one millimeter, then the accuracy of the measurement will be to the nearest millimeter (Giancoli 2005, p. 5).   No measuring device can give absolutely accurate results.   There will always be an uncertainty generated with any measurement.   The more accurate the device, the less the amount of uncertainty that will be generated, but absolute accuracy will never be obtained.   Therefore all measurements will include some error (Giancoli 2005, p. 5). The awareness of the unit size that is being used to record the measurement and the need for accuracy is a critical aspect of measurement.   Measuring an item when accuracy to the nearest kilogram is all that is needed is far easier than measuring the same item to the nearest microgram.   The difference, of course, is that in the kilogram example the amount of error is plus or minus one kilogram, and in the second case it is plus or minus one microgram. Obviously, the second measurement is far more accurate, but harder to obtain.   The smaller the unit size that the device is capable of measuring, the greater the accuracy, and normally the more expensive the device.   If great precision is not needed, then a less expensive device may be used. Consider the difference between a scale in a supermarket used to measure vegetables and a scale in a pharmaceutical laboratory that is used to measure drugs.   In the first case the scale may be accurate to only one tenth of a pound.   This level of inaccuracy is acceptable for  vegetables.   If you are buying five pounds of tomatoes, it really does not matter if you get 4.9 or 5.1 pounds.   The laboratory scale, though, must have a higher level of accuracy.   Obviously, an error of plus or minus one tenth of a pound is unacceptable in the pharmacy business.   In this case, accuracy to the nearest tenth of a milligram would be more reasonable. Another comparative example of how the awareness of the need for accuracy would affect the level of error is in the measurement of volume.   If a contractor is going to repave a stretch of street with asphalt, that contractor would measure the length and width of the road, probably in feet, and the thickness required, probably in inches, and calculate the cubic yards of asphalt needed for the project.   The amount of asphalt would be, in all likelihood, measured to the nearest cubic yard.   A cook in a restaurant adding water to potatoes is going to measure the amount in cups, with an accuracy that is dependent on the quality of the measuring cup.   Obviously the cook has a much greater need for a higher level of accuracy than the contractor.

Exam answer Essay Example | Topics and Well Written Essays - 2250 words

Exam answer - Essay Example Successful construction procurement should result in timely project delivery, proper budgeting and quality in order to meet the required functions. The act of creating a new structure requires objective survey on site, interaction with design team and other consultants, suppliers as well as other stakeholders. An immediate choice in term of the cost and quality should be agreed upon. The procurement of a construction work is often the subject of joint funding with different stakeholders who have varying interests and goals in the outcome of the projects. The following elements are the best drivers in terms of construction management: Global Bank Corporation are the owners of this project whose purpose is to take account of the demise of many European banks during the credit crunch. The success of this project will meet owner’s interest and at the same time meet the needs of their customers (Schwalbe 2009, p. 45). It is very important to first point at the factors that will determine the most suitable procurement strategy before commencing the projects. These factors: In any construction procurement, the objectives and constraints of each building project are interdependent and therefore require concurrent considerations. A competent and industrious team will be necessary to meet these aspects. Risks are events known or unknown that adversely affect the outcome of the project. The nature of the risk is determined by the objective and constraints of the project. For instance, this project is budgeted at  £120m and any activity that may cost more than the amount projected will be a risk. Consequently, it will affect rest processes and the entire project. Similarly, this project has a tight timeframe for completion. Any delay to the construction program will be a risk on the completion of the project. The responsibility of managing a given risk will be allocated to the party that has the capacity to deal with that risk. Level of project complexity

Name As Object Of Self-Identical Essay Example | Topics and Well Written Essays - 2000 words

Name As Object Of Self-Identical - Essay Example In addition, names are responsible for how we first perceive ourselves. Parents after naming their children interact with them using these names. Names describe a person’s present self and more often than not they help people in forming their own first impressions. Names, whether given by parents or individually chosen are key in developing one’s self-identity. People try to live up or run away from their names. The concept of self-identity, in recent years, has been the subject of many psychological, social and anthropology discussions (Perry, 2002, p4). This essay will analyze the influence a name or names have on the self-identity of a person, culture, organization or country. In anthropology, the term self-identity is usually in the context of ethnic identity. That is the perception of oneself, or self-sameness, in regard to others. Their joint characteristics of language and culture of the group form the group’s identity. Names and identities are peas in a pod. They are similar in nature as people confuse the two quite a lot. Names can refer to identities but they do not dictate an object’s or person’s self-identity. Names, unlike other identifying markers, are not subject to stereotyping. People rarely associate a name with a behavior or reputation; however, the name provides a platform from which a person judges his fellow human. A name, let us say â€Å"John†, quickly resonates with people. From this name, people are able to quickly know your background, compare you to other â€Å"Johns† they know, among other relevant information they have on the name â€Å"John†. These observations summarize the powerful effects a name has on others. After birth, parents spend plenty of time researching and considering the name they will give to their child (Perry, 2002, p5). Several factors are considered when choosing a child’s name as it prepares the child for the future. Parents will give strong names for their boys and feminine names for the boys. Majority of parents will choose names that are not prone to teasing or mocking by other children or people when they grow up.
