Monkey in the Mirror Essays - Essay Example But there are several things that mark us as being different from many of these other animals. Some of them are purely physical – for instance we have bipedal motion that is absent in the rest of apes (Tattersall, 2002 p. 89). But we also have many metaphysical qualities that mark us as different from our ancestors, such as the creation of music, art and culture. There is no one single thing that can truly account for all the ways in which we are different, but there are a few pieces that had to come together. One of which is our brain, which is by far the largest brain compared to body mass of any animal in the history of the world (Tattersall, 2002, p. 151). This probably had to develop in conjunction with a lot of other developments to be useful – for instance, larger brains would not have been useful if we were not already prehensile apes who were adapted to living in trees, and could thus use our prehensile hands to create and use tools (Tattersall, 2002 p. 69). Bu t probably one of the single things that sets humans apart from other animals the most is the development of speech. A change in our voice box and brain simultaneously occurred at some point in the evolution of homo sapiens, which allowed humans to differentiate themselves from previous iterations of humanity (or pre-humanity), and begin to do things that are truly novel in the animal kingdom Tattersall, 2002). One of the things that makes language so important is that it augments our innate intelligence, so that instead of things that become created instantly dying out when the person who created them dies, they can pass on the teaching to succeeding generations. This creates culture, which is probably the one biggest things that separates humans from other primates and other animals. If Gould and Tattersall were to have a conversation with each other, they would probably come to cross roads. Gould tended to entirely

Pros and Cons of Globalization Essay Example for Free

Pros and Cons of Globalization Essay Former CEO of Vodafone Group, Mr. Arun Sarin, at the 2009 Global Business Forum debated that there is a profound change occurring in the world today. The world is becoming more interconnected due not only to physical infrastructure but also the intellectual and software infrastructure that is being built; moreover, the way in that trade is being done today. For him, the United States is still the most powerful country in the world; however, if the country wants to have global excellence in the future, innovation is a most. Since its earliest appearance, about three decades ago, the term globalization has been used to describe a process, a condition, a system, a force, and an age. The term signifies a social condition characterized by the existence of global economic, political, cultural, and environmental interconnections and flows that make many of the currently existing borders and boundaries irrelevant. Globalization suggests dynamism best explained by the idea of change and the transformation of present conditions. In other words, globalization is an ongoing process rather than a static condition. According to Manfred Steger, author of the book: Globalization: A Very Short Introduction, globalization refers to a multidimensional set of social processes that create, multiply, stretch, and intensify worldwide social interdependencies and exchanges while at the same time fostering in people a growing awareness of deepening connections between the local and the distant. In the other hand, globalization is a complex and contradictory phenomenon that encompasses progress and degradation, opportunity and compulsion, freedom and restrictions. These countless contradictions are points of political contestation. Advantages of Globalization * Countries around the world have made the choice of establishing trade relationships with each other in order to improve their economy. Past hostile experiences were left behind, and globalization has announced an era of international peace and security. In addition, there has been propagation of democratic ideas among countries. * Countries have resolved to test free trade with some regions. Eliminating taxes, duties, and export/import quotas has allowed consumers to buy goods and services at a lower cost. * Globalization is encouraging the use of international connectivity such as the internet. Exchanging thoughts and ideas is helping interlink people around the world. * Several companies are investing in other markets providing better employment opportunities for skilled and unskilled labor all around the world. Globalization is helping in increasing the standard of living of the developing world; and at the same time is helping to reduce poverty. * Competition among different countries is leading to international innovation and quality goods. Consumers are benefited in the process because they get quality products at a cheaper rate and from a large variety available in the market. * Mutual trade has brought an understanding of the importance of protecting the environment and natural resources. Global environmental problems are being discussed. Disadvantages of Globalization * Many people from develop nations are losing jobs since corporations are outsourcing work to developing countries due to savings in cost of labor. There is a lot of pressure in the develop world; people are always under the threat of their job being outsourced. Outsourcing has resulted in unemployment. * Any sort of economic disruption in one nation will have a domino-effect on other nations that are closely related to that country in terms of trade and commerce. * Influence of local cultures and traditions will slowly start to wear down. Western ideas will impose over other cultures. * Globalization may lead to more environmental problems. A company may want to build factories in other countries because environmental laws are not as strict as they are at home. * Income distribution within countries is becoming less equal. The rich is getting richer and the poor is getting poorer. * Transnational integration and increased mobility has simultaneously strengthened and diminished the protection of individual rights and the dignity of individuals. Globalized markets have facilitated more monitoring of social conditions but have also opened up more opportunities for economic exploitation. Example of the pros and cons of globalization The Philippines is one of the countries in Asia that has been affected by the contradictions of globalization. The country is taking part in the process since it became part of the World Trade Organization in 1995. Globalization has allowed major changes in the nation like more labor, more Filipino foreign companies, high levels of education, and high per capita income. Philippines have four regions that globalization has targeted and these four are: liberalization, mobility of capital, technology, and management of organization through private and public sectors. Nevertheless, the Philippine state has failed in organizing a socioeconomic environment that would have prepared the country for global competition. Many Filipinos believe that globalization has done nothing for their country. And this is due to the poverty that has been becoming worse each year. The Philippines is still corrupt and still faces economic and political problems, therefore, the nation and its people does not trust the process of globalization. About 60% of the population lives in poverty and poverty levels are still increasing. The institutional framework of a country, its political culture and the quality of its leadership play an important role in fostering economic development and in promoting social welfare. For some, globalization can make the Philippines a better nation if the Philippine leaders get involve in allowing for more global trading and more foreign investors to the help boost the economy. And by accomplishing those goals, the Philippines should be able to reduce poverty levels. The Future of Globalization Globalization is transforming the structure of worldwide interaction and people are changing along with it. The positives aspects of globalization are becoming more significant than the negatives ones. In the long term, the world will be transformed into a more prosperous, democratic, and peaceful environment. This may means that cultural conflict and global chaos will occur in the short term but large economic growth and democratic governance will prevail in the long term. Globalization is making the way for free trade and international business. It is also improving communication around the world. The biggest advantage is that globalization has the potential to make the world a better place to live in. Globalization cannot be stopped; however, leaders should always be on the top of its spread and outcomes. Work Cited Steger, M. B. (2004). Globalization, a very short introduction.

The aims and objectives of our study were to characterize pathologies of paranasal sinuses on MDCT, to delineate their anatomical location, extension and bony involvement and to correlate the multi detector computed tomography findings with clinical/surgical/histopathological/ microbiological findings. A total of 100 patients who came with complaints referring to nose and paranasal sinuses were included in the study. All patients were subjected to MDCT PNS after detailed clinical examination. The imaging findings are correlated with other investigations. Key imaging features considered were significant anatomical variations, site of involvement, bony and soft tissue changes, invasion of surrounding structures, pathognomic features and correlation with clinical complaints/surgical/pathological/microbiological findings. Among 100 patients in our study, there were 15 patients in 0 20 years age group, 36 patients in 21 40 years age group, 37 in 41 60 years age group and 12 were greater than 60 years. The age group of patients ranged from minimum of 9 months to maximum of 81 years. The highest number of patients were in 41 60 years age group. The study comprised of 65 males and 35 females. The number of male patients were higher than the female patients. The patients were divided into five categories: bacterial sinusitis, fungal sinusitis, benign tumors, malignant tumors, and miscellaneous. 84 patients presented with sub acute or chronic bacterial sinusitis, 4 patients were of fungal sinusitis, 4 patients presented with benign tumors, 3 patients with malignant tumors and 5 patients with other miscellaneous conditions. Various anatomical variations were encountered during our study. One or the other anatomic variation was found in 99 cases ( 99% ). Of the structures around ostiomeatal unit, giant bulla ethmoidalis was found in 35 cases, middle turbinate pneumatisation in 33 cases, paradoxical curvature of middle turbinate in 19 cases. Haller cell was found in 15 cases. Type 1 frontal sinus drainage pathway in 78 cases, type 2 frontal sinus drainage pathway in 21 cases. Deviated nasal septum with or without septal spur in 55 cases, inferior turbinate hypertrophy in 30 cases, accessory maxillary ostia in 26 cases, and agger nasi cell in 93 cases. Type 1 optic nerve course was found in 53 cases, type 2 in 14 cases, type 3 in 9 cases, and type 4 optic nerve course along with Onodi cells in 23 cases. Type 1 anterior clinoid process pneumatisation was found in 10 cases, type 2 pneumatisation in 1 case. Sphenoid septum lateral attachment in 7 cases, and sphenoid sinus septum pneumatisation in 14 cases. Among 84 patients with bacterial sinusitis, 26 patients presented with sporadic pattern, 23 patients with infundibular pattern, 23 patients with ostiomeatal unit pattern, 8 patients with polyposis pattern, and 4 patients with sphenoid recess pattern. The various causative factors which came across in infundibular pattern were Haller cells in 6 cases, giant bulla ethmoidalis in 6 cases, uncinate process pneumatisation in 1 case, and mucoperiosteal thickening in 10 cases. The various causative factors for ostiomeatal pattern which were found during our study were: inferior turbinate hypertrophy in 6 cases, giant bulla ethmoidalis in 6 cases, deviated nasal septum with or without septal spur in 4 cases, concha bullosa in 3 cases, concha lamella in 2 cases, agger nasi cell in 1 case, and paradoxical middle turbinate in 1 case. The various findings which were encountered in bacterial sinusitis in our study were: mucoperiosteal thickening in 84 cases, ostiomeatal unit block in 31 patients, bone thickening in 20 patients, bone thinning in 8 cases, and bone sclerosis in 6 patients. Among 4 patients with fungal sinusitis, the various findings were: bilateral / multisinus involvement was found in 4 cases, expansion of any involved sinus was found in 4 cases, intrasinus hyperdensity was found in 4 cases. Bony thinning was found in 4 cases, bony erosions and nasal cavity involvement was found in 3 cases. The various findings in 4 cases of benign tumors seen ( 1 inverted papilloma, 1 juvenile angiofibroma and 2 ivory osteomas ) were: bony thinning in 2 cases, bony remodelling in 2 cases, multisinus involvement in 2 cases, intracranial extension in 1 case, and intra orbital extension in 1 case. Bony destruction, bone thickening/sclerosis, and calcification were not seen in any of the cases. Among 3 cases of malignant tumors (squamous cell carcinoma, embryonal rhabdomyosarcoma, and esthesioneuroblastoma), various findings were: : Bony destruction in 3 cases, bony thinning in 3 cases, bony remodelling in 0 cases, multisinus involvement in 2 cases, intracranial extension in 2 cases, and intra orbital extension in 2 cases. Bone thickening/sclerosis, and calcification were not seen in any of the cases. Under miscellaneous category we encountered one case each of periapical cyst, oro-antral fistula, granulomatous polyangitis, monostotic fibrous dysplasia, and Langerhans cell histiocytosis. In our study we found sensitivity and specificity for bacterial sinusitis as 100% and 94.11% respectively. The fungal sinusitis had sensitivity and specificity of 75% and 100% respectively. Benign, malignant tumors and others had sensitivity and specificity of 100%. The diagnostic accuracy for bacterial sinusitis and fungal sinusitis was 99%, and the diagnostic accuracy of benign, malignant tumors and other miscellaneous conditions was 100%. The p value was obtained after applying Fischer Exact test. The p value obtained was statistically significant for all the disease conditions. Based on the statistical values it can be inferred that multi detector computed tomography is useful to characterize paranasal sinuses lesions and also delineation of anatomical location, extension and bony involvement. There are certain limitations in our study. Our findings cannot be generalised to the whole population because of the limited sample size. However, our findings add value to the research done. The role of contrast cannot be adequately studied. The role of MRI in various paranasal sinus pathologies was not evaluated. CONCLUSION Paranasal sinus diseases are very commonly encountered problems in clinical practice. Clinical assessment alone is not sufficient to reach a diagnosis, as the presentation of most of the conditions is nonspecific. Imaging forms the mainstay not only in making correct diagnosis, but also to know the extent of lesion, pre-operative assessment of the sinonasal anatomy and commonly encountered anatomic variations. X ray has low sensitivity, specificity, positive and negative predictive values. CT is highly sensitive and specific in determining the presence of paranasal sinus pathology and clearly demonstrates the complex anatomy. The introduction of multi detector CT has transformed the axial imaging modality into a volumetric one and allows the pathology to be displayed in any desired plane. The capability of thin-section acquisition improves visualisation of tiny pathological details, and the isotropic nature of high spatial resolution data sets enables display in multiple planes, obviating image acquisition in prone or hyper extended patient position. Recommendations: 1. MDCT has proved to be highly sensitive in classifying the lesions into clinically relevant categories, making diagnosis and more so in knowing the extent of involvement with a high diagnostic accuracy. 2. MDCT is an indispensible tool before Functional Endoscopic Sinus Surgery (FESS) to accurately delineate the fine bony details that contribute to disease and also can predispose to complications which can be fatal. 3. MDCT is very useful in predicting the diagnosis of fungal sinusitis by the presence of intrasinus hyperdensity, granulomatous diseases by the presence of nasal septal perforation and intracranial or intraorbital invasion, malignancy by bone destruction and invasion. 4. MDCT can tailor the surgery according to the extent of disease. It helps in determining the prognosis of the malignant tumors depending on the site and extent of the disease. It can also obviate the need for surgery in certain conditions like polyposis. 5. MRI can be problem solving tool in differentiating inflammatory sinonasal diseases from tumors, and also for the presence of intracranial or intraorbital extension. 6. However, MRI alone cannot be performed in the evaluation of paranasal sinus diseases because of the problem of signal voids. It has to be supplemented by CT. 7. MDCT is the preferred initial modality of all imaging studies available because of its ease, availability, accuracy, precision and low cost. 1

Maria Isabella Boyd aka Belle Boyd Essay -- biographies bio biography

Have you ever dreamt of living an adventurous life? Well for me that was reality. I was a spy and actress, mercilessly charming Union officers into giving me information. Dubbed 'La Belle Rebelle' by a French war correspondent, I went by the name Belle Boyd instead of my original name, Maria Isabella Boyd. I have gone in and out of jail, marriages, and careers (three of each). Throughout the whole ordeal though, I have been constant in my loyalty to the Confederacy. Born on May 4, 1843, I was raised just like any other southern lady. My father was a merchant, and I grew up in Martinsburg, West Virginia with my parents, several brothers, one sister, and grandmother. I attended Mount Washington Female College of Baltimore from age 12 to 16. Ever since I can remember I?ve been getting into all sorts of trouble. Once when I was 10, I rode my pony into the hallway of my house causing havoc. I was known to be a fun-loving debutante. People described my voice as low and charming and my figure flawless. It was odd how I was considered either extremely beautiful or completely plain because ...

And Sun Also Rises Essay

This paper discusses Ernest Hemingway’s novel And Sun Also Rises (1926) and takes an in-depth analysis of the development of the female character Lady Brett Ashley in trying to come up with better understanding of the character’s role in the novel. Hemingway’s And Sun Also Rises is widely regarded as Hemingway’s best novel. It became the overnight Bible of the postwar generation. (Barrett, 724) The novel revolves the theme of damage done to Hemingway’s generation by the violence of World War I. All the main characters of the novel are to certain extent scarred by war. Some of them suffer physical injuries like Jake or Count Mippipopolous and others bear the psychological trauma of â€Å"lost generation† (the phrase belonged to Hemingway’s friend Gertrude Stein and became the novel’s first epigraph). Among those psychologically deteriorated individuals Lady Brett Ashley is a controversial character that evokes different readers’ and critics’ reaction. This paper explores the path by which Lady Ashley’s character develops through the novel. With the first meeting with Brett Ashley her individual female sexual appeal and exceptional general attractiveness is revealed. From the beginning of the book, men find her irresistible. When Jake, as narrator, first introduces Brett, he says, â€Å"Brett was damned good-looking. She wore a slipover jersey sweater and a tweed skirt, and her hair was brushed back like a boy’s. She started all that. She was built with curves like the hull of a racing yacht, and you missed none of it with that wool jersey† (Hemingway, 22). Robert Cohn, too, is immediately captivated by Brett, and a short time later, he says, â€Å"She’s a remarkably attractive woman† (Hemingway, 38). She is a strong and independent woman and probably these are the features that attract men more than her physical beauty. Her real tool is her charisma that strikes the men around her. Every significant male character in the novel, at one time or another, comments on Brett’s female attractiveness. When he is introduced to Brett, Bill Gorton says, â€Å"Beautiful lady† (Hemingway, 74); Mike Campbell says, â€Å"Brett, you are a lovely piece. Don’t you think she’s beautiful? † (Hemingway, 79) These compliments are like a refrain that is reiterated through the rest of the novel. Despite the abounding attention on men’s side Brett rejects to become committed to a single man, at least physically. Neither the affluence of attention nor her independence makes Brett a happy woman. Having first appeared as a careless free woman Brett Ashley turns out to be an unhappy and miserable creature just the same as all those who lived through the war. Brett is often described in the literary criticism as sexually promiscuous, or even a nymphomaniac, which seems extreme given that in the course of the story she has sexual relationships with, at most, three men – her fiancee, Mike Campbell; Robert Cohn; and Pedro Romero. Some critics, like Edmund Wilson, assess Brett’s conduct as â€Å"bitch-like†; Wilson interprets Brett Ashley as â€Å"an exclusively destructive force† (p. 238). This interpretation, plausibly, is directly related rely to Brett’s own assertion that she makes to Jake after she leaves Romero: â€Å"You know it makes one feel rather good deciding not to be a bitch† (Hemingway, 245). Nonetheless it is difficult to agree with such interpretation of Brett’s character. First of all it is known that she is one of the â€Å"lost generation†, the people whose youth fell on the post-war period when the relationships and responsibilities were loose and disordered, and so Brett’s behavior merely reflects this time. Furthermore, though Brett never stayed with any man longer than she wanted, she never displayed cruelty in attitude toward men, so she could not destruct them to any degree. And the most important thing which explains Brett’s character is again related to the time of the novel. Brett Ashley belongs to those people whose thoughts are confused being affected by the war. So while looking for her way in life she fails in finding the lull for her psychological disturbances therefore continues her self-abusive conduct. Brett can be profoundly careless of the feelings of others. She scatters cigarette ashes on Jake’s rugs, and when Romero gives her a bull’s severed ear after a successful bullfight, she leaves the gift behind, stuffed in a hotel drawer. Cohn calls her a sadist when she is unmoved by the plight of the horses gored in the bullring. Certainly she uses Jake heartlessly at times, expecting him to introduce her to a man she desires, put up with her affairs, remain steadfast in his devotion to her, and faithfully run to her rescue on short notice when she finds herself at loose ends in another country. Yet she is also deeply unhappy and emotionally fragile. Viewed more sympathetically, she can be seen as a self-destructive woman, traumatized by the ugly and unromantic loss of her first love to dysentery in the war: â€Å"Brett hurts no one in the novel as severely as she hurts herself. Her nymphomania, her alcoholism, her constant fits of depression, and her obsession with bathing are all symptoms of an individual engaged in a consistent pattern of self-abuse† (Whitlow, 56). All in her misery she often complains to Jake, her only true friend, about her aimless existence and unsatisfying life. Her vagrancy from relationship to relationship is assimilated with Jake and company roaming around bars. As the novel unfolds one observes how Lady Ashley transforms from the self-confident independent woman into one who seems extremely awkward being by herself. That is why she is searching for the shelter in more or less stable though platonic relations with Jake. As with the other characters, World War I obviously played the determinative role in the formation Brett Ashley’s character. Having lost her true love during the war she elaborated the pattern of random relations, especially with regard to men. Her skepticism and lost faith in search for true love symbolizes the search of the whole lost generation for their decayed values. Unable to find support in the traditional convictions that imposed certain meaning to her life Brett feels morally lost. Having lost belief in anything Brett together with her friends is trying to escape the reality and fill her empty life with careless wandering from bar to bar, living night life, drinking and entertaining, doing everything that fits into the notion escapist activity. The character of Lady Brett Ashley is developing through the novel from the initial impression of careless but happy woman into the typical representative of post-war generation with aimless way in life. Parties, free love and other kinds of merry-making are only the futile distraction for concealing the sorrow and insecurity that filled her soul.

Woodstock essays

Woodstock essays One didnt simply go to Woodstock: one lived through it. In August 1969, the Woodstock Festival was the largest counterculture event ever staged, attracting some 500,000 people and featuring many of the countrys top acts. Two decades later, Woodstock has come to mean more than just three days of fun and music; it symbolizes a time of community, exuberance, and intensity since lost. Woodstock festival gave power to the youth, united people of all ages, races, and sexes, and defined a generation, making it one of the most important musical events of all time. In order to understand the impact and importance of the Woodstock Festival one must first examine the society that preceded the 1960s and set the stage so to speak for the events of the Woodstock Festival. The end of World War II brought thousands of young servicemen back to America to pick up their lives and start new families in new home and new jobs. With energy never before experienced, American industry expanded to meet peacetime needs. Americans began buying goods not available during the war, which created corporate expansion and jobs. Growth was everywhere. The baby boom was underway. Part of the what happened in the 1950s with increased employment and income, families had more money to buy things. People could afford single family dwellings and suburbia was born . In the 1950s a big change happened in public education. In 1954, Chief Justice Earl Warren and other members of the Supreme Court ruled that separate facilities for blacks did not make those facilities equal according to the Constitution . Integration of the public classroom came about across the nation as Perhaps one of the things which most characterize the 1950s was a strong element of conservatism and anticommunist felling which ran throughout much of society. The phrase under G...
