A Common Language Communication Between Humans and the Great Apes free essay sample

A discussion of the sign and symbol-based language experiments conducted with great apes over the last forty years, including criticisms, findings, and implications. Addresses projects with gorillas, chimpanzees, orangutans, and bonobos. This paper addresses a number of different language experiments that have been performed with all four species of great apes gorillas, chimpanzees, orangutans, and bonobos, and the advantages, disadvantages, and relative success of each, including conducted experiments. The author discusses the physical limitations of the apes, the advantages of using sign language as opposed to keyboard and symbol-based language, and criticisms brought up by various skeptics. The paper also mentions other types of cognitive activities in which the apes have participated, including painting and learning a system of economic exchange. From the paper: The Koko Project is currently the longest running and most successful of all the ape language projects. Pattersons goal was for Koko [the gorilla] to learn 200 signs ? she now knows over a thousand, and understands at least 2,000 words of spoken English. We will write a custom essay sample on A Common Language: Communication Between Humans and the Great Apes or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page She asks questions, she lies, she tells stories, she uses the negative, she uses and understands abstract words like love, hate, and death, and she even tells jokes. One of the most famous incidents involves a conversation between Koko and one of her teachers regarding the color of her blanket. As she was getting ready to go to bed, the teacher asked Koko what color the blanket was. Koko responded red, even though the blanket was white. The teacher admonished her and asked her again, refusing to believe that Koko would make such a simple mistake. Still, Koko responded red, and repeated it several times. The teacher was perplexed. Then Koko pulled a tiny piece of red lint off the blanket, pointed to it, and signed red, and started laughing her deep, breathy, gorilla laugh. Humor, then, is another quality we humans can no longer claim for ourselves alone.

( aq ) + 2Fe3+ ( aq ) 2Fe3+ ( aq ) + 2I? ( aq ) ? 2Fe2+ ( aq ) + I2 ( aq ) 9. Mentioning to the two equations in inquiry 8. the S2O82? ( aq ) ions oxidize the Fe2+ ( aq ) ions to Fe3+ ( aq ) ions. At the same clip. the S2O82? ( aq ) ions are reduced to SO42? ( aq ) ions. The Fe3+ ( aq ) ions are strong oxidising agents that oxidize I? ( aq ) ions to I2 ( aq ) . At the same clip. Fe3+ ( aq ) ions are reduced back to Fe2+ ( aq ) ions ( i. e. the accelerator is regenerated ) . Both the equations shown in inquiry 8 involve the hit between positive and negative ions. This will be much more likely to be successful than the hit between two negative ions in the uncatalysed reaction. Therefore. the activation energy of this tract will be lower and the reaction rate will besides be higher. 10. The chemical reaction can be speeded up by the add-on of Fe ( II ) ions. which act as a homogenous accelerator of this reaction. 11. It can be regenerated after the reaction. OR It is specific in action. OR A little sum of accelerator is normally plenty for the catalytic action. 12. Homogeneous accelerator is one which has the same stage as the reactants and merchandises. Sample laboratory study Title: Investigating ways to alter the rate of a reaction with a suited accelerator Aim To plan and transport out an experiment to look into ways to alter the rate of a reaction – by the usage of a suited accelerator.

Using a measurement cylinder. 10 cm3 of ammonium peroxodisulphate solution was added to a conelike flask. 2. Using different mensurating cylinders. 5 cm3 of K iodide solution. 5 cm3 of Na thiosulphate solution. 1 cm3 of Fe ( II ) chloride solution and 2. 5 cm3 of starch solution were added to a boiling tubing. 3. The contents in the boiling tubing were poured into the conelike flask. 4. The stop watch was started instantly. 5. When a dark bluish coloring material of the starch-iodine composite appeared in the solution. the stop watch was stopped. 6. The clip for the visual aspect of the dark bluish coloring material was recorded in Table 1. 7. Stairss ( 1 ) to ( 6 ) were repeated. but Fe ( II ) chloride solution was replaced with 1 cm3 of distilled H2O. Consequences Time for the visual aspect of the dark bluish coloring material With Fe2+ ( aq ) ions ( as a accelerator ) added 59 s Without any accelerator added 3 mins and 52 s Table 1 After blending all the chemicals in the conelike flask. the reaction mixture with Fe2+ ( aq ) ions will take a shorter clip for the dark bluish coloring material to look. Analysis 1. In the absence of Fe2+ ( aq ) ions. the reaction between S2O82? ( aq ) ions and I ­Ã‚ ­? ( aq ) ions is slow. As both reactant ions are negatively charged. they tend to drive each other. However. when Fe2+ ( aq ) ions are added. the reaction becomes faster. Fe2+ ( aq ) ions have the same stage ( i. e. aqueous stage ) as the reactants and merchandises. so they are homogenous accelerator of this reaction. 2. Fe2+ ( aq ) ions is a cut downing agent which can cut down S2O82? ( aq ) ions to SO42? ( aq ) ions. The Fe3+ ( aq ) ions formed act as an oxidizing agent. which oxidize I ­Ã‚ ­? ( aq ) ions to I2 ( aq ) ions and renew Fe2+ ( aq ) ions once more. Bing a accelerator. Fe2+ ( aq ) ions are non consumed in the catalytic procedure. Discussion 1. Either Fe2+ ( aq ) ions are Fe3+ ( aq ) ions is a good pick of accelerator for this reaction because the interconversion between Fe2+ and Fe3+ facilitates the reaction between S2O82? ( aq ) ions and I ­Ã‚ ­? ( aq ) ions to happen. 2. The catalytic belongings of Fe2+ ( aq ) ions may be due to the fact that it is easier for the negatively charged S2O82? ( aq ) ions to near the positively charged Fe2+ ( aq ) ions. The same is true when the positively charged Fe3+ ( aq ) ions formed can near the negatively charged I ­Ã‚ ­? ( aq ) ions easier. 3. The experiment is merely a simple trial tubing experiment but the consequence ( color alteration ) is rather obvious and easy to observe. Decision The chemical reaction can be speeded up by the add-on of Fe2+ ( aq ) ions. which act as a homogenous accelerator of this reaction. Answers to inquiries for farther idea 11. It can be regenerated after the reaction. OR It is specific in action. OR A little sum of accelerator is normally plenty for the catalytic action. 12.

Managerial Traits and Skills Research Paper Example | Topics and Well Written Essays - 1000 words

Managerial Traits and Skills - Research Paper Example 2). High level of emotional intelligence is fundamental to the good relations between a manager and the subordinates as well as the clients. Emotionally intelligent managers know how to tackle the challenges that are encountered by them on daily basis. Emotional intelligence inculcates a sense in the manager to deal with others without getting caught in dysfunctional conflicts with them. This enables them to achieve the organizational objectives without having to exert unnecessarily. Dealing with people in the appropriate way in context of a certain situation is not a rule of thumb. It is more of an art. Emotionally intelligent managers have the intrinsic feeling of behaving the right way, which may not necessarily require the manager to be patient all the time. There are times when it is better to let go of things and yet there are times when the manager needs to take serious action in order to control the situation. The manager derives this sense from emotional intelligence. ... locus of control inculcates confidence in the managers that they are able to control the circumstances and mould them according to the need of the hour. On the other hand, managers who have external locus of control tend to underestimate their ability to control the circumstances. Instead, they tend to think that things will happen as they are destined to be. While the significance of destination cannot be undermined, it is equally important for a manager to believe that his/her destination is in his/her own hands. Without this belief, the manager lacks the confidence required to play his/her individualistic role in the change of circumstances for the better. Interpersonal skills of an individual have a large impact on his/her effectiveness as a manager. Interpersonal skills, as the name indicates, are the skills required to deal with people. Interpersonal skills are linked to emotional intelligence and the two have a cause-and-effect relationship. High level of emotional intelligenc e inculcates sound interpersonal skills in the manager. The fundamental key to the improvement of interpersonal skills is knowledge of business ethics. Business ethics teach a manager what is the right thinking which needs to be adopted for the evaluation and analysis of matters. Teamwork is essential for a manager as he/she is frequently required to work as part of a team. Teamwork is essentially a skill that is not very common in people. Different people have different problems that affect their tendency to be effective as a team member. Such problems include but are not limited to attitude problems, neuroticism, and group think. Some people are not able to get along with others well. This may happen because of a contrast between others’ beliefs and perceptions and theirs. This causes

Personal statement for PhD admission Example | Topics and Well Written Essays - 500 words

For PhD admission - Personal Statement Example The program itself is predicated on a heavy research background; something that I am partially familiar with and interested in understanding and engaging to a more profound degree. Essentially, my current research background has been limited to a 2012 publication in the Academic Journal of Chongqing University of Posts and Telecommunications. However, I also engaged in a great deal of research with respect to my Master’s degree while studying at the University of New Haven. Moreover, my internship at China Taiping Insurance Company helped me to realize that very few current issues that are represented throughout the world can be addressed without performing adequate research and understanding the unique variables that tie in to each and every situation. Quantitative and qualitative research in terms of crime prevention and sociological understanding are of primal interest to me as well. Although I only had a few opportunities to leverage these interests in undergraduate school, I fully intend on focusing on both of these methodological approaches within a graduate program. Likewise, focusing on crime theory and sociological ramifications of crime is a predominant interest that I have with regard to the field. Similarly, as with any other field of study, understanding dynamics of crime and crime prevention ultimately reduces to an understanding of finance; something that further intrigues me. Essentially, these are two differentiated research interests and ones that I believe can lead to further relevant understanding of the field of criminal justice. The first relates to the way in which crime can be better understood and potentially prevented, whereas the second is mainly contingent upon the resources that individual departments a llocate to crime scene investigation and how this correlates with their overall rates of successfully solved crimes. Obviously, these two research interests

Social Contract Theory of John Locke Essay Example | Topics and Well Written Essays - 750 words

Social Contract Theory of John Locke - Essay Example It works in a way so that no one can deny that a rule is unjust because the rules are made when all members of the society agree to them. John Locke, one of the greatest eighteenth century theorists, also put forward the idea of natural rights and property, which formed the basis for his social contract theory. However, this is opposed to the central idea of egalitarianism – all people have an equal right and claim on the resources of the society. The social contract theory negates this concept and relies solely on individual rights rather than communal rights. Also, some perceive this negatively and argue that Locke’s studies tend to be more conservative in nature compared to other theorists of the social contract theory and included only the males and the educated and propertied class of the society (Cohen, 1986). Pollock (2006) explains that the Lockean ‘contract’ is one where individuals give up the freedom to aggress against others in return for their own safety. The government or any law-enforcing authority rests upon the principles of quid pro quo which means that we give the government the power to protect us, in full recognition of the fact that this power may be used against us. However, this ‘contract’ with the government comes with a set of principles. Locke rejects the notion of an unconditional duty of obedience: ‘For him the legitimacy of political authority depends upon the end for which it was instituted, namely, the preservation of the natural rights to life, liberty, and estate. If these rights are infringed, the trust between the community and the magistrate (government) is canceled, and the people have a right to appeal to heaven (revolution) to establish a new legislative body.’ (Gray, 1999). Therefore, Lockean version of the social c ontract theory allows the members of the society to initiate a revolution if the social contract’s

Celtic Christian Art Origins and Development

Celtic Christian Art Origins and Development How Celtic was Celtic Christian Art? The art of the Early Christian Period has been regarded as an Irish phenomenon representing the survival in Ireland of La Tene artistic traditions. (Laing, 1975, 339) It has gained considerable attention due to its wealth of ornamental metalwork, illuminated manuscripts and stone structure. However there is still the debate How Celtic is Celtic Christian Art? The term must first be analysed in order to understand the characteristics of Celtic Christian Art. The high point of this Insular art of the early Christian era was the creation of a series of illuminated Christian manuscripts, notably the Book of Durrow (c.650) and the Book of Kells (c.800), as well as such metalwork masterpieces as the Ardagh Chalice, the Derrynaflan Chalice, the unusual Moylough Belt Shrine, famous processional crosses like the Tully Lough Cross and the Cross of Cong, and the secular Tara Brooch. Within this essay I will attempt to summarise the origin and development of Celtic art in Great Britain and Ireland. As a result, this would assist my analysis on the significant influence Christianity had on Celtic art. A breakdown on examining Celtic art, is to begin defining the term. The term Celtic Art is defined by the people who spoke the Celtic language and embraced their traditions. Thus explains the characteristic decorative motives, for instance the divergent spiral were of foreign origin. However, one must understand that the conversion of the inhabitants of Britain from Paganism to Christianity was a gradual process, extending over a period of several hundred years. Therefore the evidence for the existence of Romano-British Christianity is scarce. Out of the several hundreds of inscribed and sculptured monuments belonging to the period of the Roman occupation of Britain there are hardly any which bear Christian symbols or show traces of Christian art.(Allen, 2001, 162) Moreover another misinterpretation about the term was that many believed the term came from art found in a church or a specific object. The term usually means art which embraces the character of Christianity. A number of problems must also be considered such as assessing beyond the religious aspect of the Celtic Christian tradition, creates a challenge as distorts the image of the range of material which may once have existed. Robert Lloyd Laing supports this view as he suggests that the Early Christian Art is a complex amalgam of artistic traditions which became blended together in the fifth to seventh centuries.(Laing, 1997, 339) Another issue of reliability of using other sources (for instance the La Tene Art), to assess the Christian Celtic Art, as it creates some imperative variations. Whilst La Tene art is undoubtedly of the same genus as that of the early Christian Celts, the variety in vogue after the fourth century AD was markedly different.(Laing, 1987, 5) These difficulties must therefore be interpreted by using the Celtics traditions and its influences from outside elements. This would allow a descriptive analysis of the origin and changes within Celtic Christian Art. Ireland was one of the very few countries that were never colonized by Rome. Unlike Britain and Continental Europe Irish Celtic art was neither influenced by Greek or Roman art. Between the end of the Iron Age and the gradual emergence of Christianity in Ireland a prominent feature within the Irish culture was its unbroken tradition of Celtic culture influenced only marginally by Roman art. Furthermore, Christianity gained more attention with the arrival of St. Patrick in the 5th century CE. This along with the significant introduction of the renaissance of Hiberno- Saxon style or Insular art which was caused by the mission of Aidan of Iona in the 630s to the ancient kingdom of Northumbria, were was especially important in the later development of insular Celtic art and changed the Celtic Christian art. The spread of Christianity throughout Ireland introduced the Irish monastic art. Archaeological evidence such as the monasteries became the principal artistic centres which aid archaeologists, to understand the origin and development of Celtic Christian art. Thus emphasises the impact of Christianity on Irish art and should not be underestimated. A renaissance in the arts was created due to the close connection of the network of monasteries throughout Ireland, Britain (especially Northumbria) and parts of Europe. All these monasteries combined acted as centres of learnin g and artistic craftsmanship as well as places of religious devotion. Thus resulted to the illumination of manuscripts and the enhancement of Celtic designs taken from jewellery and metalwork produced for the Irish secular elite, but most insular art came about because of the patronage and direction of the Catholic Church. Christian Celtic art can generally be summarised by looking at stone crosses, illuminated manuscripts, and metal objects such as chalices, shrines and reliquaries. The art of this period utilized traditional Celtic curvilinear designs enriched with foreign influenced brought back to Ireland by returning missionaries-motifs such as the Saxon use of entangled, interlocking animal forms in geometric decorations. The art of the Anglo-Saxons came into contact due to the Irish missionaries. They practised the traditional colourful animal style in metalwork which became a significant aspect within Celtic art as they associated the animals to individual gods and myths. This is supported by Paul Jacobsthal who analysed that The Scythian animal style expresses a Eurasiatic beast-mythology, a totemism which was all its own. (1935, 113) This shows a subtle influence Christianity had on Celtic Art as the people of the time are beginning to assess animals with religion. However there are limitations with using the animal designs for understanding the changes within Celtic art. Allen suggests that Animal forms are comparatively rare in Late-Celtic art, as they are not interlaced, so that it is almost useless to seek for the original inspiring idea in this direction. (2001, 250) Nevertheless we could still establish a connection with the La Tene compositions and the animal ornaments. For instance from Donore a disc was found; it demonstrated an elaborate composition of trumpet scrolls in tinned bronze, placed against a richly textured background. The sophistication of this striking pattern may be compared to the great Chi-Rho page of the Gospel book, the Book of Kells, which was preserved at the nearby monastery of Kells, Co. http://www.visual-arts-cork.com/irish-images/kells-chi-rho-page.jpgMeath for many centuries. The Early Christian Mediterranean artistic traditions would be similarly seen amongst the Frank and Lombards in which these missionaries would have travelled. In addition this connection would have produced a shared manuscript for illuminators, metalworkers and later, monumental sculptors which enabled the basic houses to foster a new art form in northern Britain and Ireland. The most notable artefacts of Christian Celtic Art were dominated by ornaments such as trumpet scrolls, fine spirals often designed to be seen as a reserved line of metal in a field of red enamel. This pattern is best exemplified on the escutcheens of a series of vessels called hanging bowls. These bowls are most likely to be found in Anglo-Saxon cemeteries in eastern and southern England. In addition these bowls have a distinct decoration which is more likely to be Celtic in character. Allen suggests that The closest resemblance between the spiral decoration of the Pagan period and that of the Christian period is to be found on the discoidal ornaments with patterns in champlevà © enamel, forming the attachments of the handles of certain bronze bowls, several examples of which have been discovered from time to time in different parts of England.(2001, 243) the distinctive Celtic character is often argued, for instance some archaeologist believe that it represented booty taken by the conquerors from the Celtic lands and others believe it was uniquely religious. Another important artefact of the time was the Book of Durrow. It is another illuminated manuscript of the Insular style. There are unique textual peculiarities which create a similarity with the Book of Kells. It was seen as one of the most outstanding early manuscripts in the history of Irish art. The illuminated text includes the four Gospels of the New Testament, along with the six surviving carpet pages (which were believed to have been devoted for decoration). It is furthermore suggested that it was linked with the earlier patterns of Celtic metalwork. Unusual symbols are assigned to the gospels which do not follow tradition: a man for Matthew, but an eagle for Mark (instead of the traditional lion), a calf for Luke, but a lion for John (instead of the traditional eagle). These symbols along with the cross which unites them amplify harmony if the Gospels and the argument that early Christian art had influences from the Celtic tradition. This is furthermore supported by the interlace pattern-work, spirals, zoomorphic triskeles, and knots, which were all derived from Celtic art. OSullivan agrees with this argument as they suggested that In Durrow it is followed by a page of abstract design based on Celtic ornament, the first of five so-called carpet-pages, one of which originally faced the opening of each gospel. (2005, 526) In the late 7th to early 8th century, Irish missions in Europe produced the most impressive Celtic Christian art in Europe. This is shown in the illuminated manuscripts of the Bible, which were embellished with decorative borders and astounding intricate, inventive lettering. The complexity of the twining geometric designs dominated previous art, the rare representations of human faces and figures were abnormally stylized. Another book which was considered just as important as the Bible and was seen as a masterpiece of its time was the Book of Kells. The Book of Kells shares the monumentality of its conception with some of the later Pictish cross-slabs, decorated with a wealth of biblical and secular scenes (Laing, 1979, 168) This book was deemed as the most famous, finest group of manuscripts of the 6th through to early 9th centuries, in the monasteries of Ireland, Scotland and England. The book had many similar features to the bible, it included the iconographic and stylistic traditions and the decorated letters, which were usually found in incipit pages for the Gospels. Large stone crosses were also seen as a significant aspect in evaluating how Celitc Celtic Christian art was during its time. During the later eighth and ninth centuries the form of the ringed High Crosses came of great importance. Many of the crosses are devoted to Christian scriptural themes but one early group, probably mostly ninth century in date, is dominated by abstract interlace ornament, the La Tene animal interlace, and key- and fret-patterns. Pure ornament plays a major part also on the crosses with figured scenes and frequently occurs in the form of bossed fleshy scrolls. These sculptural works reached their high point during the early tenth century, as evidenced by Muiredachs Cross at Monasterboice, County Louth, and the Ahenny High Cross in Tipperary. The free-standing crosses, in which the outline of the stone corresponds with the outline of the cross, are the most highly developed type of Celtic sculptured monument of the Christian period, and are therefore presumably the latest, with the exception of those of the decadent period just before and after the Norman Conquest.(Allen, 2001, 188) These crosses were vital in understanding the Celtic Christian art, they were carved with interlacing relief decorations such as ceremonial religious objects, which ornamented with gold filigree and coloured enamel stud. An example of this type of cross would be the Ardagh Chalice. The Ardagh Chalice largely conceals its Christian symbolism, but it carries two medallions on its bowl that contain prominent crosses of arcs.(Duffy, MacShamhrian, Moynes, 2005, 141) This highly sophisticated design is considered one of the finest works of Insular art. Stokes suggested that The Tara brooch and the Ardagh chalice offer the most perfect examples of the use of this peculiar spiral that have been found in the metal-work of Irish Christian Art;(2004, 63) The Ardagh Chalice itself is made from a silver-bronze alloy and its main features include delicate gold filigree work, ornate handles and the use of semi-precious and coloured stones and enamels. The overall impression is that of a master craftsman at work and probably dates from the eight century. Another significant chalice was the Derrynaflan Chalice which was considered to be one of the most outstanding religious artworks in the history of Irish art. It was made in the eigth and ninth century by Irish metallurgists. These were highly skilled craftsmen who had superlative artistic skills during the Insular Art period (c.650-1000) in the ultimate La Tene style. Duffy, MacShamhrain and Moynes analysed that the Derrynaflan Chalice is less colourful than the Ardagh Chalice however its filigree is of great interest because it shows elements of common Christian iconography griffons, birds, beast, and quadrupeds, probably lions that are widespread in early medieval European sculpture and metalwork as part of the Tree of Life and related motifs. (2005, 141) Brooches are also very useful in examining How Celtic is Celtic Art? In Ireland, the Celtic brooches were a perfect example of the type of jewellery the high-status people used to wear. Many of the brooches features include symbols that have come to epitomize the Celtic culture; examples such as Claddagh, the Brigids cross, the Celtic hound and the classic example of Celtic interlace are typical patterns for Celtic art. The most popular Celtic brooch is the Tara brooch design. The Tara brooch design and the Hunterston brooch are considered to be two of the most important evidences in Celtic Christian art. Hourihane suggests that It has long been recognized that while both brooches show elements from the native Celtic La Tene repertoire, their design also reflects outside influences and incorporates many foreign elements.(2001, 211) The Tara brooch is a classic example of an artefact from early Christian-era Ireland. It dates around 700AD and features an embellished circle with a long, straight pin. It is a representation of the Celitc peoples brilliant craftsmanship. The Hunterston brooch is one of the earliest examples of decorative brooches from Britain and Ireland. Solid silver with gold and silver filigree and amber studs compose the head and pin of the brooch. The style of the brooch derives from the Pictish tradition in its presentation of zoomorphic creatures.Brooches can be found on monument al sculpture of the Mullaghmast stone, in which they appeared to be used for carrying variants of the early hanging bowl style. Moreover during the period of 800-100AD, silver became exceedingly popular with the Irish and Anglo-Saxon metallurgists, thus led to the creation of well-noted brooches. In conclusion Celtic Christian art was very Celtic as just like all art, it was inspired by religion. The Celts paganism was different to that of the Greeks and Romans as it was supported by the authority of druids, who were the guardians of writing, teaching, culture and most importantly religion. Their polytheistic ideas manifested themselves through animals, various monsters and collective goddesses, (Gods and demigods were usually depicted on coins). Thus, this explains the popular use of zoo morphology in their art. In addition to understand Celtic art we must analyse the unity between the materials and techniques the people of the time used. For instance Celtic art consists of hard or hardened objects such as metal, stone, wood, leather, glass and clay. There is no painting (except on pottery), no wax, no wickerwork and virtually no weaving. Iron engraving and abstract sculpture in bronze both derive from the Ancient Celts who combined the techniques of engraving and sculpting most effectively. Their strong point was the creation of tiny sculptures, particularly for the embossed engraving of coinage. Another form of unity was their common use of animals. Frequent subjects such as the quadrupeds, birds, fish and reptiles are often represented, along with the merge of plant designs which lend themselves into transformations. The Celts favoured using animals and plants than those depicted humans, thus makes it simple for an archaeologist to identify Celtic Christian art. The very human representations which were found are usually a form of an imaginary being for instance a monster, as though everything in the world were metaphysically linked. The treatment of these subjects is a source of bafflement for, in each case, the Celts present us with riddles. In conclusion, to answer the question How Celtic is Celtic Christian Art? an archaeologist must look at the common traditional themes which continued through to the Early Christian art. The complex, twining geometric designs predominated; the rare representations of human faces and figures were abstract and stylized, would assist us in judging how Celtic, Celtic Christian Art was at the time.

Biological Effects Of Radiation :: essays research papers

The Biological Effects of Radiation   Ã‚  Ã‚  Ã‚  Ã‚  Whether the source of radiation is natural or man made, whether it is a small dose of radiation or a large dose, there will be some biological effects. Radiation causes ionizations of atoms, which will affect molecules, which may affect cells, which may affect tissues, and so on. Although most people tend to think of biological effects in terms of the effect of radiation on living cells, in actuality, ionizing radiation, by definition, interacts only with atoms by a process called ionization (Chandra p. 205). Thus, all biological damage effects begin with the consequence of radiation interactions with the atoms forming the cells.   Ã‚  Ã‚  Ã‚  Ã‚  Even though all subsequent biological effects can be traced back to the interaction of radiation with atoms, there are two mechanisms by which radiation ultimately affects cells. These two mechanisms are commonly called direct and indirect effects.   Ã‚  Ã‚  Ã‚  Ã‚  If radiation interacts with the atoms of the DNA molecule, or some other cellular component critical to the survival of the cell, it is referred to as a direct effect. Such interaction may affect the ability of the cell to reproduce and, thus, survive. If enough atoms are affected in such a way that the chromosomes do not replicate properly, or there is a significant alteration in the information carried by the DNA molecule, then the cell may be destroyed by â€Å"direct† interference with its life-sustaining system.   Ã‚  Ã‚  Ã‚  Ã‚  Indirect effects are caused by the reaction of radiation with the water that makes up the majority of the cells volume. When radiation interacts with water, it may break the bonds that hold the water molecule together. This produces fragments of hydrogen and hydroxyls. These fragments may recombine or they may interact with other fragments to form compounds, such as water, which would not harm the cell. It is when these fragments combine to form toxic substances, such as hydrogen peroxide, that the destruction of the cell results.   Ã‚  Ã‚  Ã‚  Ã‚  Biological effects of radiation are typically divided into two categories. The first category consists of exposure to â€Å"high doses of radiation over brief intervals of time† producing acute effects (Hall p. 15). The second category represents exposure to â€Å"low doses of radiation over extended periods of time† producing chronic or long term effects (Hall p.15). High doses tend to kill cells, while low doses tend to damage or change them. High doses can kill so many cells that tissues and organs are damaged.

The Brothers Karamazov by Fyodor Dostoevsky Essay

The parable of the Grand Inquisitor is told by Ivan to Alyosha found in the novel, The Brothers Karamazov by Fyodor Dostoevsky. Both Ivan and Alyosha are brothers. The difference is in their respective religions wherein Ivan is a dedicated atheist while Alyosha is a monk. The parable is an important component of the novel and also one of the most famous passages in modern literature because it contains ideas about human freedom and nature. The parable also consists of a fundamental ambiguity. The leadership of the Grand Inquisitor is based on his amazing and exceptional strength to have freedom that has endured that majority of the human beings found it so terrible. From his point of view, only people who have knowledge enough to lie and who have the strength to endure suffering by being forced to make lies can rule over those people who want to stay weak, disillusioned and obedient. The Grand Inquisitor made an accusation against Christ of only speaking to the strong in spirit and can endure freedom while he is enforcing dogmatic solutions and continues his ministry to the weak. This style of leadership by the Grand Inquisitor can be compared to the leadership of Socrates. The Socratic method is described as the series of questions that are prolonged and answers that will refute a moral principle by letting the opposing argument to come up with a conclusion that will contradict the person’s original point of view. Socrates developed this style as a way to examine, refute or shame the opponent into reversing his earlier opinion. The Grand Inquisitor challenges the very essence of human life, the concept of evil and the free will of man. The concept of freedom is being examined and is described using a perspective that is bleak and contemptuous. The ideologies of man is being depicted as being a destructive force that has brought down humanity into chaos and anguish. The parable can be perceived as an attack on religion and God but a closer look will reveal a conclusion that remains the opposite. It is concluded that the Grand Inquisitor becomes the explanation for the crucial need for a religious institution. The context of the parable may be a shock to religious advocates. God will visit the earth in the form of flesh and blood. He performs miracles and is imprisoned in a cell by a man who punishes him for giving free will to mankind. It is clear from the beginning of the story that Alyosha is religious while Ivan is being cynical in his position on the matter. After the Grand Inquisitor becomes aware of the presence of God here on earth, he orders his men to capture him. The depiction of the Inquisitor has contradicted the description of God’s human form. The Inquisitor is being presented as a formidable, cold and judgmental and sinister. Another contrast that can be found between God and the Inquisitor is the reaction of the crowd to both of them. The people displays a fearful obedience as their behavior towards the Inquisitor and not the same adoration and awe like before. It is noted here that the people is quick to abandon God who in such a short time before they were all so enamored with. The weakness of man as a theme and the need for a rigid government will begin will begin to come out. A lengthy monologue follows which is delivered by the Grand Inquisitor to God. The lecture talks about the Inquisitor’s reprimand for freedom. The Inquisitor is speaking against the internal freedoms that are borne out of man’s free will. He describes how freedom has enslaved humanity and placed the human race into a state of disorder and chaos. He confronts God on this error and boldly declares that the human race will reject Him ultimately. The argument of the Inquisitor is difficult to refute as the ability of man to differentiate the good from the evil is undoubtedly questionable. The freedom of the will permits every individual to have a different system of morals or in some instances having no morals at all. If one will put into consideration the violence and the deprivation that is happening in the world everyday, it seems that man cannot manage the freedom that he enjoys with his will. The many choices and responsibilities, the moral decisions that he has to make on a daily basis has already overwhelmed so many. The mind has the ability to create an environment of its own by making hell out of heaven. This ability of the mind is what the Inquisitor has spoken of and has claimed that it has led to the destruction of mankind. There are many people who make choices in their lives that paved the way for the creation of circumstances that are hellish in nature. It is not the responsibility of free will that comes with it that overwhelms mankind. The reference of evil and the existence of God can also be found in the Confessions of Augustine. A person only needs to look around the world and have the realization later on that something is not quite right. The existence of evil is one of the challenges that have puzzled many Christians and those that are not for that matter. For most of Ausgustine’s life, he tried to find a solution for it. The question of the existence of evil can be reworded in many ways. One approach could be to address the source and beginnings of evil that will prompt a series of statements that will eventually form an argument with reason. It is said that God is the creator of all things. Evil is also a thing so therefore God also created evil. If the first arguments were true, then there is no escape to the solution. This formula is frustrating for the whole of Christianity. God would not be known as good if he intentionally created evil. Augustine has approached the problem from a certain angle. He questions if there is any convincing proof that God exists. If there is any proof that would suggest and lead to the conclusion that he really does, then God could not possibly be capable of creating evil. Evil must have come from something else. He also had an observation that evil could not be selected because there really is no certain evil thing to choose. A person can only turn away from good preferring a lesser good over a greater good since everything is good. For when the will abandons what is above itself, and turns to what is lower, it becomes evil – not because that is evil to which it turns, but because the turning itself is wicked† (Augustine 2007). Evil is therefore an act of choosing the lesser good over th greater good. To him, evil comes from the free will of the people. Evil was a perversion of the free will in man who turned away from God in preference of lesser things. Back to the Grand Inq uisitor, Satan or evil has obviously grown impatient by the values of kindness, humility and love that he has found to have no defenses and forced to capitulate. He is powerless with the overwhelming humility that he is forced not to live up to his threat of burning Christ at the stake. The prisoner is released and is allowed to walk freely and safe. Before the release, the prisoner gave a valedictory kiss on the lips of the inquisitor. Satan was a rebel in heaven. Because he wanted to rule, he preferred hell. In the continuing political power struggle, he has claimed the world to be his own and has a message for Christ to keep out of his world. The ends justify the means. The previous statement aptly characterizes a consequentialist’s way of reasoning. The outcome or result of an action when beneficial is morally right regardless of the means to get the end result. Consequentialists for example think of what they want, how they are going to get it and what the good in it is if they take action towards their goal. Deolontologists would be thinking of the rationality of an action and base it on a moral rule to know if it is right or wong. Comparing the personal identity of both theories, consequentialists consider the will, reason and desires as important in determining morality. Meanwhile, deolontologists consider only will and reason because they believe that desires only distract the mind from thinking rationally. Desires reflect emotions and in deolontology, there is no room for that because the moral rule is to be followed. Regardless if they want to do something or not, they must perform their duty because the performance of it is morally right. The rationality of consequentialism is in getting what you want out of that action. You want to achieve something because it is beneficial for you. Therefore you think of actions to take that would lead to the things you want and bring you the greatest good. Reason dictates the actions of deontologists. It is in reasoning that deolontologists discover what is right or wrong based on moral principles. The primary source for evaluating morals in consequentialism is the consequence of an action while in deolontology, it is the actions themselves. The virtue of consequentialism may be the feeling of having maximized the utility available. For deolontologists who are performing their moral duties, it the feeling of having done the right thing. However, both of these theories have criticisms in their arguments. One of the criticisms by Anscombe state that in consequentialism, it is not clear what one ought to do because the validity of the action is based on the consequences. As compared to deolontology, the theory suggests what one should do because the validity of an action is based on moral principles. These moral principles have a definite description of what is right and wrong. In another criticism by Thomas Nagel, consequentialism should not encompass those actions that are morally wrong but produced positive results in the long run. An example of this would be an uprising by the people of a country. The action of the people may be considered treason and according to the moral rule, that action is wrong. Because of the uprising, the corrupt government was toppled and it was replaced by new government that is elected by the people. Consequentialism is an ethical theory that in which the consequences of a particular action becomes the basis for an acceptable judgment on that action. It finds the source of a moral value in a good situation and results into a consequence of that action. Many forms of consequentialism exist and the most common is utilitarianism. The theory puts emphasis on the â€Å"good† as the center of its concept. Utilitarianism holds that actions that result to the greatest good to a greater number of people are considered to be moral actions. The outcome of an action makes that action either moral or immoral. In consequentialism, emphasis is given to the results or consequences in analyzing what is right and wrong in our actions. If the result of an action has a positive outcome then it is considered as moral and therefore right. Likewise if the action produces negative outcomes, the action becomes wrong and immoral. Deontology is another ethical theory that is of Greek origin, deos which means duty and logos as science. Using its etymological meaning, deontology becomes the science of duty. The theory argues that understanding our moral duty and its regulations to help us decide on the right choice. If we do our duty, we are doing the right thing. Doing our duty is considered a moral behavior. The theory states that we are obeying God when we do our duty for it is He that determines it and its regulations. The moral actions of deontology are separate from the consequences brought about by those actions.

Importance of Enlightment Ideals in To Kill A Mockingbird essays

Importance of Enlightment Ideals in To Kill A Mockingbird essays The French Revolution was a time of immense refinement that lasted from 1789 to 1815. During this period, new ideas of natural laws based on reason influenced the minds of individuals and political affairs. The attempt to provide rational explanations was called the Enlightenment. These thinkers began to advocate changes and reforms. The reforms were referred to as the Enlightenment ideals and were used to perfect society. The Enlightenment ideals consist of equality towards all people, against cruel and unusual punishment, tolerance towards others, natural rights, will of the majority, and the idea people are basically good. Harper Lee created a novel which flashbacks to the Enlightenment ideals. Her novel, To Kill a Mockingbird was written in 1960 about Scout Finchs childhood and the struggle of Maycombs society in the 1930s. The key Enlightenment ideals and beliefs are highly palpable in Harper Lees novel, To Kill a Mockingbird. The ideals of equality, toleration of others, and po sitive view of human nature are illustrated despite Maycombs propensity to degrade individuals. Throughout her novel, Lee conveys the importance of equality among all people and races. Due to Maycombs lack of equality, the differences in social classes of the society are both irrational and destructive. Lee uses the childrens confusion to evaluate the equality in Maycombs society, ultimately, the prejudice in human relations. Aunt Alexandra replies to Scout, Because he is trash, thats why you cant play with him. Ill not have you around him, picking up his habits and learning Lord-knows-what, when she asks to play with Walter Cunningham (Lee 225). Equality towards all people regardless of their background or color is vital and is the basis of the Enlightenment and of the novel. The implication of equal treatment among people is intertwined with having to ...

Free Essays on Frida Kahlo

I chose to watch the movie Frida. Frida Kahlo was one of Mexico’s most famous artists. She was known for her candid portraits depicting the emotional and physical pain she experienced throughout her life. Frida is about the struggles we face throughout our lives, and how we can overcome these hardships with love and friendship on our side. As a young adult, Frida was seriously injured in a trolley accident. The accident left her bed-ridden for months, due to severe injuries to her body. Doctors said that she would not be able to walk again. During this time, she developed her talent for painting. Miraculously, Frida makes a full recovery, but the medical expenses drained her family’s finances. Frida decided to try to become a professional painter to help support her family. She went into Mexico City in search of professional critique from the successful painter Diego Rivera. Diego immediately recognized her talent and offered to help her. They quickly fell in love and Diego proposed marriage. And though Diego is known for his brief affairs with his nude female models and other admirers, Frida cautioned him not to betray her and accepted the marriage proposal. Their life together was enriched with adventure and high profile parties, as Diego took high paying commissions in the United States. But his career in A merica quickly fell apart when he refused to change his painting philosophy despite political pressures from his client. Returning to Mexico, their personal and financial lives continued to unravel. Frida picked up painting again, while trying desperately to make her family life work. Frida is a beautifully performed and produced movie, thanks to the dedication of Salma Hayek who worked so hard to get this movie to the big screen.

Free Essays on Frida Kahlo Free Essays on Frida Kahlo In the self-portrait of Frida Kahlo with cropped hair – 1940; the imagery is so odd that it evokes an almost dream like setting; Frida Kahlo gazes out expressionless, with a mask like stare. Usually known for her native Mexican costumes of long ruffled skirts and embroidered blouses, and for weaving ribbons, flowers and jewels into her crown of braids, here Frida Kahlo appears in a baggy man's suit with her hair cut off (MoMA). She appears weak. Her arms are limp and her hands barely hold a pair of scissors and a strand of hair the evidence of her self-destruction. The fresh-cut strands float and squirm in her barren surroundings, entwining themselves around her chair. It's almost as if her energy has been exhausted from her body and into her loose strands of hair. By rejecting the trappings of so-called "feminine" attire, Kahlo was making herself undesirable to her unfaithful husband, the Mexican muralist Diego Rivera whom she had divorced earlier the same year (MoMA). Her ne w "masculine" guise was meant to deflect his superficial admiration, superficiality echoed in the words from a popular Mexican song written at the top of the painting: â€Å"Look if I loved you, it was for your hair. Now that you are bald, I don't love you anymore.† Although the subjects of Kahlo's paintings are often personal, her style is rooted in Mexican art, especially in nineteenth-century religious painting. The Surrealist leader of that time, Andrà © Breton, described Frida’s work as â€Å"a ribbon around a time bomb† (MoMA). Frida Kahlo’s response was â€Å"I never knew I was a surrealist till Andre Breton came to Mexico and told me I was† (Masters).... Free Essays on Frida Kahlo Mexico’s Woman Frida Kahlo’s mother was a devout Catholic of mixed Indian and Spanish blood. Her father was born in Germany, the son of Hungarian Jewish Immigrants. He moved to Mexico City, and later studied photography becoming infamous for his photos of Mexico’s Colonial architecture. This background and the Revolution of 1910 drew Frida into focusing the Indian part of her heritage. It was reflected in her behavior ,her appearance, her art, and even in her home decor. When Frida was a small child she became ill with polio, leaving her right leg shrunken. She always remembered her father being very supportive and drove her in her mental and physical development. Her pastimes at this age were reading, singing, drifting into a fantasy world, and as she got stronger she was involved in sports. Frida was excepted into the National Preparatory School in 1922, heart set on becoming a doctor. During this time every one had â€Å"revolution fever† in Mexico, including Frida. She joined a left wing group called Cachuchas renowned for their smarts and their playful ways. She even changed her birth date from 1907 to 1910 to correspond to the Mexican Revolution beginning. It was at her Preparatory school she first met her future Husband, Diego Rivera. She became smitten with him at first sight even telling a group of friends that it was her goal to have a child by him. Though not a good student she was high spirited, strong willed, rebellious, and an avid reader in Spanish, German, and English. In 1925, her life was flipped up-side-down when she was in a near deadly bus accident. Her back, foot and pelvis were broken badly when a handrail pierced her body. She had over 30 surgeries but never fully recovered, but in public she was as strong as ever she rejected her pain with a laugh. Her flowing long shirts that she always wore were to cover her limp.

Operation management of Tom Pulling Toys Essay Example | Topics and Well Written Essays - 1250 words

Operation management of Tom Pulling Toys - Essay Example The intention of this study is Tom Pulling Toys as a global manufacturer of educational toys. Its toys are being manufactured in China and sold in the European and US markets. However, due to rising competition and increasing customer complaints, the company is in a spot of bother. To tackle the situation the company is planning to adopt Total Quality Management practices in its operations. As a starting step, the company has decided to use Statistical Process Control at one of its doll manufacturing lines. For this, data collection has been done over a 30 day period. The data collection has been done from the point of view of colouring defects and the height of dolls as these were the two areas the customers complained about. As an output of the analysis on the collected data, the company needs to know whether its processes are in control. The company also needs recommendations in case the processes are not in control. For the first set of data regarding the number of colour defecti ves, firstly the mean number of defectives is calculated. C-chart is the most suitable chart for this purpose since it is used when number of defects or errors is given and the size of sample (here 200) is constant. Using the mean the two 3 sigma control limits are established as: Lower Control Limit (LCL) = c bar – 3 * (c bar)^.5 Upper Control Limit (UCL) = c bar + 3 * (c bar)^.5 The minimum value of Lower Control Limit can be 0. Hence, a negative value for the same is replaced by 0. The mean number of defectives, LCL and UCL are obtained as 6.033, 0 and 13.402 respectively. C-chart is plotted using the number of defectives and control limits. The same is shown in Figure 2.1. Figure 1: c-chart for Number of defectives From the chart, it can be observed that one data point lies above the UCL indicating that the process is not in control. However, since only 1 out of 30 points lies outside, it can be removed by outlier analysis. For the second data set, x bar and R charts are appropriate. For R chart, the ranges are calculated for each of the 30 samples. Mean range or R bar is then computed as an average of these ranges. The 3 sigma control limits for R chart are then established as: Lower Control Limit (LCL) = R bar * D3 Upper Control Limit (UCL) = R bar * D4 The R bar, LCL and UCL are obtained as .5533, .254 and .853 respectively (Table of Control Chart Constants). R chart is plotted using the ranges, mean range and the two control limits. The same is shown in F igure 2.2. Figure 2.2: R chart for height of doll From the chart it can be observed that a large number of data points lies outside the two control limits. This shows that the process is out of control. For x bar chart, the mean height for each sample is calculated and then mean of mean heights (x bar bar) is calculated. The 3 sigma control limits are the established as: Lower Control Limit (LCL) = x bar bar – R bar * A2 Upper Control Limit (UCL) = x bar bar + R bar * A2 The x bar bar, LCL and UCL
