Olympics as a Platform for Political Protests Essay
Olympics as a Platform for Political Protests - Essay Example Some people believe that by using the Olympics as a platform for political issues, they exert pressure upon oppressive governments and such governments may be forced to change their regime. It is a fact that 2008 Olympics to be held in China has sparked lots of debate. The above writer believes that these protests are actually prompting the Chinese government to review their policies towards Tibet. The latter country is fighting for independence and in order to gain international support, there is a need to choose the right movement when all eyes are on the host country. Such people argue that if they were to choose another time like after the Olympics, very few countries will be interested in the problems of China. Also using sporting events as a platform for political issues allows other countries to demonstrate their disdain about the actions of those oppressive regimes. There are also claims that host countries need to foster the image of the Olympics. This means that they need to portray the peace and unity that is synonymous with the event. If a host country has not been doing this, then it can be seen as a form of hypocrisy. The Chinese government has been criticized for its human rights abuses. There have reports about how the Chinese government prevents its citizens from discussing issues about their government. Furthermore, the Chinese government normally discourages most foreigners form discussing their problems claiming that it has nothing to do with them; they believe that they are the only ones with a right to solve their problems. In light of these arguments, it would be quite unfair for such a government to hold the Olympics and claim that they foster the spirit of unity that is synonymous with the torch. (Rice, 2008) Some people believe that protests should be conducted in any platforms a long as there is room to be heard. Furthermore, they believe that sometimes members of the host country may not have the political freedom to do so consequently, the international community needs top help them in this. For instance, there are numerous goods in the US government that come form the Chinese government. But workers in that location have minimal access to basic resources. Most of them are subjected to harsh working conditions and low pay. They cannot complain about this situation because it may bring problems. Consequently, the international community needs to help the Chinese workers by voicing their complaints. These complaints will only be noticed when the country stands to loose something. For instance, if the international countries boycotts the Olympics, then chances are the Chinese government will loose a lot. It may therefore be promoted to change their worker's conditions due to these chang es. Arguments against using the Olympics as a platform for political protests 'Sport is sport and politics is politics. There has never been anyone who has belied the fact that sport is the best way of uniting peoples.' (Brincat, 2008)

IEEE Technical paper based on 1597.1 standard in Electromagnetic Lab Report
IEEE Technical paper based on 1597.1 standard in Electromagnetic compatibility - Lab Report Example To achieve this, we performed a series of shielding effectiveness (SE) tests for a board level shielding product with different apertures by means of a reverberation chamber. An analytical shielding effectiveness formulation has been developed in comparison with the shielding effectiveness (SE) measurement results. When performing tasks related to electromagnetic shielding, Board Level Shielding (BLS) is widely used for isolating electromagnetic interferences. A typically perfect Board Level Shielding (BLS) is deemed to have no apertures and it is fixed to the ground plate of the circuit board all round in order to reach maximum shielding effectiveness (SE). By introducing several apertures, we can be able to make the Board Level Shielding (BLS) lighter weight and increase its convenience. To evaluate the effect of the aperture size and the total number of apertures on the shielding effectiveness, several tests were performed in the lab and a number of apertures of different sizes and the results obtained were compared. The results are processed and used to plot the corresponding shielding effectiveness (SE) data using calculation tools based on the shielding theory. The IEEE standard 1597.1 demands that we use feature selective (FSV) to compare the level of agreement between the reference and the numerical results. In this method, the data sets are compared by decomposing them into two parts: This approach involves taking the overlapping portion of the two datasets and interpolating them so that they share a coincident x axis location. A Fourier transformation is then used to transform this data. The two data sets are low (DC), band (L0) and high pass (Hi) filtered. The six elements are then inversely transformed. Comparing the trend data gives the Amplitude Difference Measure (ADM). Shielding effectiveness of an aperture

The Relationship Between Extroversion And Physiological Measures Psychology Essay
The Relationship Between Extroversion And Physiological Measures Psychology Essay There has been a substantial research into the relationship between how extroverted an individual is and their physiological measures (Eysenck, 1967, cited in Martin, Carlson, Buskist, 2007). Many studies have been carried out across the world to investigate this relationship and how environment and genetics can contribute to extroversion within individuals. The present study looked at the relationship between extraversion and physiological measures in Psychology undergraduate students in the UK. No significant correlation was found between extroversion and heart rate or extroversion and galvanic skin response. The relationship between extroversion and physiological measures in university students There has been much research into the relationship between arousal in response to a number of different tasks in both introverts and extroverts. Eysenck (1967) (cited in Martin, Carlson, Buskist, 2007) suggested extroversion is a reflection of the state we do not show within our central nervous system (CNS). He stated that happiness and sociability were two of the main traits associated with extroversion. In a study investigating happiness and extroversion in undergraduate students, it was found that the two were significantly correlated. These differences support the idea that introverts are different to extroverts in that extroverts seek out more stimulating environments. The present study set out to investigate further into this idea by looking at the relationship between extroversion and physiological measures in Psychology students at a university in the UK. Studies into the origins of extroversion within an individual have been widely conducted to understand why a person may be so extroverted or introverted; heritability seems to play a large contributing factor. In a study comparing monozygotic twins and dizygotic twins, monozygotic twins were shown to give the most alike results with 70% of the twins tested, being similarly extrovert (Zuckerman, 1991, cited in Martin, Carlson, Buskist, 2007). This study does not support the idea that extroverts are affected by their environment unlike most research into extroversion, it simply states that genetics are the cause. Similar studies to this report have supported previous research like into whether biological factors differ within introverts and extroverts. A study into physiological measures and extroversion was carried out in Singapore where the results showed lower extroversion scores were correlated with heightened cardiovascular reactivity while higher extroversion scores were correlated with lower cardiovascular reactivity. The study also found that higher extroversion was linked to lower cardiovascular reactivity during stress tasks and seemed to affect how individuals express and cope with anger (Jonassaint et al., 2009). This study helps to support the notion that Eysenck proposed which says that introverts are more likely to feel uncomfortable in a stimulating situation, in this case cardiovascular activity, whereas extroverts are more likely to enjoy and seek out such environments. Heart rate and skin responses have also been significantly associated with male students performing a visu al vigilance task who were measured on the Eysenck personality inventory as introverts (Gange, Geen, Harkins, 1979). Research has also found differences in the brain between extroverts and introverts. In a study looking into whether there is a correlation between extroversion and blood flow when smelling unpleasant and pleasant odours, the part of the brain known as the amygdala in the temporal lobe, was strongly correlated with cerebral blood flow and higher extroversion scores when exposed to the pleasant odour (Vaidya et al., 2007). This piece of research supports the idea that extroverts are genetically different to introverts as they enjoyed the experience of the pleasant odour more than introverts did and their brain activation within the temporal lobe further supported this idea. Other studies have further supported how the environment, not genetics, may affect both introverts and extroverts and how they react differently. In a study investigating the effect of background music and noise on completing tasks in introverts and extroverts, it was found that introverts performed better overall on each task except one, and introverts appeared to be more affected by the presence of everyday music and noise than extroverts. (Cassidy MacDonald, 2007). Introverts are also more likely to respond more quickly to louder noise bursts than extroverts who tend to respond equally rapidly to varying noise intensities (Britt Blumenthal, 1991). These studies supports Eysenckà ¢Ã ¢Ã¢â¬Å¡Ã ¬Ã ¢Ã¢â¬Å¾Ã ¢s theory, which says that people whose brains are over-aroused, will find stimulating situations uncomfortable, and they will seek out quieter environments. Although this idea seems to be strongly supported, a study which researched Eysencks (1953) hypothesis of a relationship between extraversion and sympathetic nervous system activity used 42 undergraduate students and the outcome was not quite the same. These students were exposed to fear arousing conditions and their heart rate and galvanic skin response (GVR) were measured during this time (Small, 1976). Although you would expect a relationship, no significant correlation was found. This piece of research disconfirms Eysenckà ¢Ã ¢Ã¢â¬Å¡Ã ¬Ã ¢Ã¢â¬Å¾Ã ¢s hypothesis and this may be due to individual differences. In other words, maybe some extroverts are not under aroused and are actually over aroused, or maybe Eysenckà ¢Ã ¢Ã¢â¬Å¡Ã ¬Ã ¢Ã¢â¬Å¾Ã ¢s personality questionnaire is not as accurate in its outcomes as we may think when measuring personality. Although studies have been conducted in this area of research, the piece of research in this report was carried out to further provide support for this area of study. The relationship between extraversion and physiological measures was tested on Psychology undergraduate students at a university in the UK. It used a questionnaire designed to measure extroversion within an individual and a short maths test which was provided to cause the participants CNS to go into a state of high arousal. Based on previous findings, the hypotheses were that there would be a strong negative correlation between extroversion and heart rate and a strong negative correlation between extroversion and galvanic skin response. Method Participants Participants were 167 psychology students aged 18-65 studying at the University of Chester in Cheshire. The measures were taken from the sex ratio 1:4 males: females and the study used a stratified sampling method. Participants were treated in accordance with BPS guidelines and informed consent was obtained from each participant before taking part. Materials and apparatus The materials used included record sheets to write down the results for each participant, the maths task comprising of ten questions, rising in difficulty, using +,-,x and / operators, the Biopac (Biopac MP30 unit) with elecrodes (SS2L and SS3L leads to measure heart rate and GSR), the EPQ consisting of 23 questions which was filled out before the physiological measures were measured and a stopwatch to time each participant for 3 minutes completing the maths task. Procedure After initially consenting to take part in the research, students were given a 23 item questionnaire to complete, designed to measure how extroverted they are as people. Once completed, students were attached to BIOPAC consisting of electrodes being attached to the wrist, fingers and ankles which measured galvanic skin response and heart rate and given a maths task to complete, designed to get harder as you progressed in a small laboratory room for three minutes. They were timed using a stopwatch by another participant who had already taken part outside of the laboratory room. Once timed, results were taken from a ninety second interval of the three minutes and the mean was calculated using the BIOPAC software. The means were written down, both for heart rate and GSR. Design and analysis This was a repeated measures study. Participants took part in both the easy and difficult task. Heart rate and galvanic skin response were measured whilst the difficult task was being completed. Results Average heart rate scores from 137 participants were correlated with their EPQ scores using a Pearson correlation. This was conducted using SPSS v.20. The scatterplot is shown in Figure 1 below: The Pearson test showed no correlation between average heart rate scores and EPQ scores and the result was found to not be statistically significant. (r(137)=-0.049, p=0.567). Total EPQ scores from the 137 participants were also correlated with average GSR scores using a Pearson correlation. The scatterplot is shown in Figure 2 below: The Pearson test showed no correlation between average GSR scores and EPQ scores and the result was found to not be statistically significant. (r(137)=0.020, p=0.820). Discussion The results showed no significant correlation between extroversion and heart rate and so the null hypothesis could not be rejected. The correlation between extroversion and galvanic skin response was also not significantly correlated and so the null hypothesis was accepted. This study does not lend support to the findings of previous studies in this area of research into extroversion and physiological measures. A study Singapore mentioned in the introduction of this report found that extroverts were linked to lower cardiovascular reactivity during stress tasks and this seemed to affect how these particular individuals expressed and coped with anger (Jonassaint et al., 2009). Contrasting even further with the findings of this study, heart rate and skin responses have also been strongly correlated with students performing a visual endurance task who were scored on the EPI as introverts (Gange, Geen, Harkins, 1979). However some studies have also provided no support for the hypothesis of physiological measures being linked to extroversion. Small (1976), studied students exposed to fear arousing conditions whilst their heart rate and GVR was measured. He found no significant correlation, supporting the notion that extroversion does not correlate with physiological measures within different individuals. In addition to biological factors not always differing between introverts and extroverts, the environment playing an important role has also been criticised. In a study investigating the effect of familiar everyday or verbal noises on the cognitive performance of introverts and extraverts, no significant correlation was found (Avila, Furnham, McClelland, 2012). This piece of research provides evidence of there being no clear correlation between extroverts and introverts differing physiologically. Although the results did not provide significant hypotheses to support the notion that extroversion and physiological measures correlate, care must be taken with research that does support this idea. The direction of causality may be difficult to establish within this area of research. Physiological measures may not be caused by extroversion but other underlying factors. In a study by Cassidy MacDonald, 2007, introverts appeared to be more affected by the presence of everyday music and noise when completing written tasks than extroverts. However studies similar to this trigger issues as the outcome of results may not have been due to extroversion, but other personality traits of the participants. For example it may simply be that an individual may struggle to complete tasks or write when there is noise or music in the background. In this study extroversion was measured beforehand but there is a possibility that the results they obtained may have been due to demand characteristics wh ereby a participant may have wanted to look more sociable than they actually are. This would make them score highly on an extroversion scale but in reality they are much quieter and so should have been scored as an introvert. This would cause the piece of research to lack validity. In order to make this study more reliable, another study contained different participants should be carried out to ensure that similar results are obtained. Although the present study in this report contained a good sample size and had individuals from different age groups as its participants, it did not provide enough evidence to support the theory that extroversion causes an individual to enjoy stimulating environments, which in this case was the maths test. However, the findings in this report do lend support to the idea that extroversion and physiological measures are not strongly linked to one another (e.g. by Small, 1976). Overall, findings in this area of research lend support to the notion of encouraging children to become confident from a young age. For example, the more extroverted a person is, the more likely they are to be sociable and talk to others before a job interview and the more desirable they seem to be during such an interview (Caldwell Burger, 1998). In conclusion the present study found no significant correlation between extroversion and physiological measures in university students aged 18-65 in the UK and so cannot support Eysencks theory of extroversion. Future research into physiological measures and personality traits could be carried out to help support Eysencks theory; research into personality types as well as extroversion and individual traits could help to see which personality types cause certain physiological measures as well as particular traits more specifically. This could enable us to understand what truly causes a person to be an extrovert or an introvert, whether the answer lie in heritability and genetics, or the environment itself.

Violence in Our Schools Essay -- School Violence Essays
Violence in our Schools Children today are growing up in an increasingly violent atmosphere, both in society in general and in their schools. While there is no easy answer as to how to end this violence once and for all, we can look at some of the causes and take steps to contain that which we can. The main contributing factor in all recent school shootings has been the shootersââ¬â¢ feelings that they were bullied by and alienated from the rest of the children and were made to feel that they were not as good as their peers. Being targeted by the other children and having nowhere to turn to for help can cause a build up of more anger until, finally the alienated child is unable to take anymore. They struck out at their peers in what seems to them to be the most effective way, by eliminating them. Although several factors enter into school violence, the most obvious way of preventing violence is to eliminate these feelings of being outcast by oneââ¬â¢s peers. If we want to put an end to school violence , we need to put an end to bullying behavior (Shore, 1996). Many instances of bullying behavior can be linked back to the climate in which a child was raised. Those who are raised in poverty or who have no good role models will frequently suffer due to the lack of examples of adults in productive roles. If the ââ¬Å"coolestâ⬠guy in the neighborhood is a gang member, then his or her bullying behavior will be emulated by the children in the neighborhood, continuing the cycle of abuse. This pattern usually leads to other negative traits such as becoming easily provoked and developing an inability to solve problems effectively. When these traits are continued in the school system, they are compounded by peer-pressure and the lack of faculty support. The bullies soon learn that they are free to abuse whomever they wish, and although faculty and staff help when they can, there are simply not enough resources necessary to catch and prevent bullies from targeting their peers (Bennett-Johnson, June 2004 p199). One way that children are targeted is based on how he or she is treated by teachers and faculty. According to Andrea J. Cook in Columbine Author Speaks Out, those who are ââ¬Å"just rightâ⬠or are smart, attractive, and good at sports, are treated well by teachers, because they appear to be everything a teacher wants in a student. Those who are not ââ¬Å"just rightâ⬠are treated po... ...ents in their academic accomplishments. Recognizing successes of students and teachers and celebrating the positives brings back school pride and willingness to make a difference (Shore, 1996).

Aquatic Biomes and Tropical Rainforest Essay
An aquatic biome is an ecological community dominated by water. This biome can be broken down into two categories: oFreshwater, which includes rivers, streams, ponds, lakes and freshwater wetland. oMarine or saltwater, which includes oceans, seas, estuaries, coral reefs and saltwater wetland. Each of these aquatic ecosystems can be defined by variables such as temperature, the presence or absence of light, and the availability of nutrients. Aquatic biomes cover almost all the world (around 75% of the surface) and only 3% of them are freshwaters. Freshwater ecosystems This ecosystem is defined as having a low salt concentration of less than 1%. It helps to make up all the different animalsââ¬â¢ life in this planet. Ponds and lakes range in size from few yards to thousands miles across, and they are divided into the littoral zone, limnetic zone and the profundal zone. The littoral zone is the part of the lake or pond which is shallow and located near the shoreline. In this zone there is abundant light, nutrients and plants. Those plants provide protection and food for animals, insects and crustaceans. The limnetic zone is offshore, where the water is deep and it receives enough sunlight to support life. There are tiny forms of life called as phytoplankton, which are tiny plant forms, and zooplankton, which are tiny animal forms. Those tiny forms of life lead to bigger animalsââ¬â¢ life such as fish, which feed from those planktons. The profundal zone is beneath the limnetic zone, where it doesnââ¬â¢t receive light to sustain plantsââ¬â¢ life. The organisms that die from above this zone settle down and are being eaten by decomposers. Because ponds and lakes are isolated from other bodies of water, they donââ¬â¢t have new species of animals or plant, or it is limited. Streams and rivers are defined by the flow of water in one direction. The source of these regions can be the snowmelt from the mountains, runoff of rains, or the outflows of a lake. They flow until they empty into another body of water and they usually lead ultimately to oceans. The flow of water of streams and rivers changes as it moves. At high elevations (mountains), the waterââ¬â¢s flow moves swiftly and makes them clear and oxygenated. As it moves slower, it allows a more diversity of plants and animals. Because the waterââ¬â¢s flow moves slowly, it carries more sediment and there is less oxygen in the water. Wetlands are standing waterââ¬â¢s regions that support aquatic life. Wetlands can receive many names such as swamps, marshes and bogs. Marine or saltwater This ecosystem is defined by its high salt concentration. Oceans are the large aquatic ecosystem that dominates the Earthââ¬â¢s surface. It is divided into four zones: the intertidal zone, the pelagic zone, the benthic zone and the abyssal zone. The intertidal zone is the area that is covered and uncovered with the rising and falling of tides. Because of this, the communities are constantly changing and most of the living organisms live only where the high tides reach. The pelagic zone is the area away from the lands, which is the open ocean. This zone receives little sunlight and it has abundant plankton, which feed animals such as whales. In this zone, there are still some plants anchored to the bottom of the shore. The benthic zone is beneath the pelagic zone and it doesnââ¬â¢t receive sunlight, which makes it darker and colder. The abyssal zone is the deepest area beneath the benthic zone. This area is very cold, it has a great pressure, but it has a low nutrient level. Coral reefs are abundant in tropical water and it consists of a barrier of corals, anemones, and algae. The sunlight penetrates this area, which makes the water clearer and allows a diversity of living organisms. Estuaries are those areas in which freshwater merge with the ocean. This supports animals such as oysters, worms, and crabs; and supports plants such as algae and seaweeds. Tropical Rainforest Biome This is the most diverse terrestrial biome on Earth. It has a warm and moist environment and is dominated by broadleaf evergreen trees. The combination of constant warmth and moisture makes the tropical rainforest a great environment for many plants and animals, which made this biome as the only one that contains the greatest biodiversity in the world. Because of the great quantity of trees in this biome, the soil is infertile and acidic. This is because when an organism decomposes in the soil, the plants absorb it quickly for their quick grow and survival. This biome has several layers of vegetation. The tallest trees reach approximately 50 meters; below them there is a continuous canopy of treetop of approximately 40 meters. And the lower level is composed by small plants, mosses, and fungi. Most of the fauna in this biome is arboreal because the food near the ground is scarce.

The History of the Hygrometer
The History of the Hygrometer A hygrometer is an instrument used to measure the moisture content ââ¬â that is, the humidity ââ¬âà of air or any other gas. The hygrometer is a device that has had many incarnations. Leonardo da Vinci built the first crude hygrometer in the 1400s. Francesco Folli invented a more practical hygrometer in 1664.In 1783, Swiss physicist and geologist, Horace Bà ©nà ©dict de Saussure built the first hygrometer using a human hair to measure humidity. These are called mechanical hygrometers, based on the principle that organic substances (human hair) contract and expand in response to the relative humidity. The contraction and expansion move a needle gauge. Dry and Wet-Bulb Psychrometer The best-known type of hygrometer is the dry and wet-bulb psychrometer, best described as two mercury thermometers, one with a wetted base, one with a dry base. The water from the wet base evaporates and absorbs heat, causing the thermometer reading to drop. Using a calculation table, the reading from the dry thermometer and the reading drop from the wet thermometer are used to determine the relative humidity. While the term ââ¬Å"psychrometerâ⬠was coined by a German Ernst Ferdinand August, 19th-century physicist Sir John Leslie (1776-1832) is often credited with actually inventing the device.à Some hygrometers use the measurements of changes in electrical resistance, using a thin piece of lithium chloride or other semiconductive material and measuring the resistance, which is affected by humidity. Other Hygrometer Inventors Robert Hooke: A 17th century contemporary of Sir Isaac Newton invented or improved a number of meteorological instruments such as the barometer and the anemometer. His hygrometer, regarded as the first mechanical hygrometer, used the husk of oat grain, which he noted curled and uncurled depending on the humidity of the air. Hookeââ¬â¢s other inventions include the universal joint, an early prototype of the respirator, the anchor escapement and the balance spring, which made more accurate clocks possible. Most famously, however, he was the first to discover cells.à John Frederic Daniell:à In 1820, British chemist and meteorologist, John Frederic invented a dew-point hygrometer, which came into widespread use to measure the temperature at which moist air reaches a saturation point. Daniel is best known for inventing the Daniell cell, an improvement over the voltaic cell used in the early history of battery development.

Free Essays on Buddism
Buddhism is one of the major religions of the world. It was founded by Siddhartha Gautama, the Buddha, who lived in northern India from c.560 to c.480 BC. The time of the Buddha was a time of social and religious change, the development of trade and cities, the breakdown of old tribal traditions, and the rise of many new religious movements that answered the demands of the times. These movements came from the Brahmanic tradition of Hinduism but were also reactions against it. Of the new sects, Buddhism was the most successful and eventually spread throughout India and most of Asia. Today Buddhism is divided into two main branches. The Theravada, or "Way of the Elders," the more conservative of the two, it is mainly found in Sri Lanka, Burma, and Thailand. The Mahayana, or "Great Vehicle," is more liberal, it is found mainly in Taiwan, Korea, and Japan, and among Tibetan peoples, where it is known by its emphasis on he Buddhist Tantras. In recent times, both branches, as well as Tibetan Buddhism, have gained followers in the West.... Free Essays on Buddism Free Essays on Buddism Buddhism is one of the major religions of the world.

Carnival Major Aspect Of Trinidadian Culture Social Policy Essay
Carnival Major Aspect Of Trinidadian Culture Social Policy Essay What is culture? According to La Belle and Ward (1996), a current definition of culture encompasses the shared attributes which delineate one group as separate from another ( p. 28). A slightly more specific definition for this very broad term comes from Frantz Fanon who says that a ââ¬Å"culture is first and foremost the expression of a nation, its preferences, its taboos, and its modelsâ⬠(2004, p.177). From this standpoint we will examine Trinidadian culture or more specifically the significance of Carnival, an integral part of Trinidadian culture, as an outpouring of expression which originated with the French Roman Catholic aristocracy and later was influenced by slaves and former slaves. We will also examine the role it plays in inspiring national pride and uniting the Trinidadian diaspora. According to Mr. Walcott we have lost much of our historical legacy and it is from this loss and the consequent necessity for something to fill that void that the innovation of our cu lture (i.e. Caribbean culture) materialized (Walcott, 1974, p. 6). I disagree with Mr. Walcott on this point. I believe that a great deal of history was lost yes, whether it is because it was irrelevant as he says or not is in itself immaterial for the purpose of this discussion. It is my opinion that culture was not simply an upwelling of inventiveness due to large gaps in historical memory, but also an amalgamation of what historical heritage was left behind regardless of the fact that it was in tatters. If we take Carnival as an isolated part of culture, this point can be proven as we examine the origins of Carnival and see for ourselves that it began in Trinidad with a French Roman Catholic tradition of the aristocracy (Zavitz & Allahar, 2002) in the pre-emancipation era as a last prelenten celebration, which symbolized the abandonment of propriety. It was transformed with the advent of emancipation from a celebration in the form of masked balls, song, drama and dance which indi rectly, covertly and subversively confronted issues of social restrictions of class and race, since most wore masks, into a fusion in the post-emancipation period of West African religious practices and beliefs and the pre-existing French celebration (Nurse, 1999). The initial celebration of Carnival by the recently freed slaves was in the form of re-enacting a scene that they had become all too familiar with and which they had named ââ¬ËCannes Brulà ©esââ¬â¢ or burning cane (Carnival). This is one instance of creation such as that which Mr. Walcott speaks of, however we can clearly see that the entirety of the Carnival practice, once taken as a whole, contains old and new elements, old from both French and African historical celebrations separately and new from the synthesis of new ideas based on experiences and the mixing of two cultures together, one forcibly oppressed for many years, and the other, living in extravagance comparatively. Let us now take a look at what Carni val is, what it symbolizes presently for the citizens of Trinidad and Tobago. Carnival as seen by the spectator and masquerader alike is not viewed as anything static. ââ¬Å"It is a dynamic and fluid processâ⬠(Green, 2007, p. 206). It is a vibrant, exuberant, triumphant, colourful display on the one hand of freedom from oneââ¬â¢s inhibitions as passed down from the originators of this festival, in which fast-paced, up-tempo music urges revelers to jump and gyrate in time with the syncopations of the melodic ââ¬Ësocaââ¬â¢ music (Green, 2007, pp. 207-208). Feathers, beads, staffs, headbands, bright dramatic make-up, sequins, beads and all manner of shiny things bob and weave with the rhythm of the uninhibited who proudly bare their costumes and newly fit bodies for cameras and tourists alike. Big music trucks patrol the streets with thousands cavorting to the tune reverberating from the massive speakers that take up the entire truck-cab and face in all directions. This maddeningly spectacular display of peacock-like feathers, glitter and lithe bodies strutting to the beat, begins on Carnival Monday morning with ââ¬ËJââ¬â¢Ouvertââ¬â¢ which means opening of the day and continues right through into ââ¬ËLasââ¬â¢Lapââ¬â¢ on Tuesday night until the stroke of midnight (Scher, 2002, p. 461). This is the part of Carnival that is marketed, packaged and sold to the masses every year. The package includes the enticement of watching steel-bands vie for the title of champion in the Queenââ¬â¢s Park Savannah, during Panorama, the most renowned steelpan competition during the Carnival season. It is not to say that this is all that Carnival consists of, however when considering the diasporic culture of expatriate Trinis, as they are called, and their descendants, these are the images that bring to life that longing for the homeland and have inspired stirrings in the soul to return to Trinidad, just to participate in this festival of colour an d unadulterated elation. The term diasporic mentioned refers to the dispersion of a community away from its homeland to more than one peripheral region, which remembers or has some cultural connection to the homeland and is not fully acknowledged as a member of the current country (Clifford, 1994, p. 304).

How is the Enlightenment connected to the Scientific Revolution Essay
How is the Enlightenment connected to the Scientific Revolution - Essay Example People thought the globe was the midpoint of the cosmos (Bacon 1960). That meant that the moon, planets, and the sun revolved around the earth. Europeans used ideas based on the physical world while Romans and Greeks believed in the Bible. However, attitudes changed in the mid 1500. A spirit of curiosity gave rise to a scientific revolution (Burns 2003). Scholars were willing to question old ideas and the level of focus was improved with much observation. Europeans were leading in the exploration leading to discovery of new lands and the establishment of universities. Francis Bacon, an English writer, assisted in fostering this approach. He urged scientists to base their opinions on what they could see in the world (Bacon 1960). R. Descartes used mathematics and logic to exert his immense influence. In the mid 1600, Isaac Newton established the law of gravity. He used mathematics to show the law of gravity controlled the motion of the planets and objects on earth (Burns 2003). Paris became the European cultural center in 1700 (Oslar 2000) where people from the entire Europe gathered to new ideas about enlightenment. Marie Therese became popular for hosting and funding ideas on enlightenment. According to the letters by Isaac Newton, religion and uniqueness were necessary for innovation. In the letters, Newton said that the discovery came as a result of patient thought. The letters contained significant propositions but were imperfect in some parts. According to Isaac Newton, no matter how matter was scattered, it would be infinitely attracted towards the center (Hankins 1985). This meant that at the center there would have a particle that is attracted to all other particles at equal measure (Goodman 1973). This became known as a state of perfect equilibrium. According to the observations of the great instauration by Francis Bacon, human intellect is responsible for its own challenges and difficulties (Oslar 2000). Therefore, man should use the help at his dispo sal to address the difficulties that he faces. This exposed the levels of ignorance and the damage it causes to the quality of life. He argued that through human efforts and determination life can be restored to the perfect condition or reduced to better condition that it is now (Burns 2003). Mathematics and philosophy grew so rapidly that the two had to be separated (Sax 2001). The impact is still being felt today. Scientist came to know that observing and explaining would help them in discovering the natural laws. The scientific method became increasingly prominent (Portar 2001). The discovering had an impact on education in all levels. As more people trained in science and physics, technology advanced and new technologies were discovered. Enlightenment had unprecedented impact in the quality of life (Goodman 1973). Complicated farm machinery and textile industry were discovered causing scientific and the industrial revolution (Sax 2001). Scientific revolution sought a break from a religious and theological approach to life (Hankins 1985). In medieval times, society was largely governed by church views and traditions which discouraged open-mindedness (Oslar 2000). Enlightenment was a movement that challenged people to think and make independent decisions. Newton, Descartes and Priestly played a significant role in the discovery of sextants slide rule and

Career Field Analysis - Essay Example A case for this type of lawyer includes the handling of representation for clients whose injuries have resulted from negligence or harm by another person, government organ, and company or through another party. In essence, a personal injury lawyer safeguards the interests of citizens, employees, and consumers of products as they handle cases of injuries that may result from the use of faulty consumable products, automobile, medical negligence, work related injuries among a list of other possible causes. As much as this line of work focuses on attaining compensation for a plaintiff, it involves intense research over a case in which the lawyer has the obligation of applying ethical practice in the execution of their duty (Currier and Thomas 18). Over the years, a personal injury law practice has been on the increase with the increase aspects of industrialization and globalization, but this has also met quite a number of resistances especially in the USA. Many of the civil personal injury cases have been successful as the complainants have been able to secure adequate compensation for the injuries acquired from accidental or neglectful causes either at their places of work or through the government making this practice to relevant to the current times. As earlier mentioned, a personal injury lawyer begins practice by studying all aspects of law, then branch out to specialize in this line of defending the rights of the oppressed. Therefore, there is no shorter way to being this type of lawyer as one has to branch out and specialize in one aspect of personal injury litigation. The specialization aspect helps a personal injury lawyer to gain experience and knowledge in one area of litigation in order for them to deliver representation that is of quality to the clients that they represent. Some begin as personal injury lawyers practicing in other peopleââ¬â¢s law firms, then end up setting up their own practices after

Reaction paper - Essay Example Indeed, if one really thinks hard, it was right that running out of gas was made illegal because it could have been dangerous for other speeding cars. It is no wonder that car manufacturers like Volkswagen, Porsche etc. were inspired to design and create new high speed models with low friction tyres, massive engine and sensitive suspension system which could attain great speed. But today, the speed limit on autobahn is imposed because of two major reasons: increasing traffic and to promote conservation of forest land that was being adversely impacted due pollution emitted by high speeding cars. Interestingly, autobahns have seen fewer accidents as against American interstate. The reasons could probably be contributed to conscientious Germans who have great road sense and road authorities who mandate strict driving criteria for its drivers. The autobahns have inspired other countries like America to create such network of long highways which connect far away states and nations. The au tobahns of Germany have indeed become a world symbol for super highways where one can still experience the exhilaration of extreme speed.

Student Council Structure Essay Example for Free
Student Council Structure Essay This article deals with the nature of student councils and the responsibilities of the representatives across the B schools in India with the example of the successful change in the structure of the student council at TAPMI. Student council is a curricular or extra-curricular activity for students within grade schools around the world. The student council helps share studentsââ¬â¢ ideas, interests, and concerns with teachers and school principals. They often also help raise funds for school-wide activities, including social events, community projects and school reform. Wiki According to Several Schools: A Student Council is a representative structure for students only, through which they can become involved in the affairs of the school, working in partnership with school management, staff and parents for the benefit of the school and its students. Almost all the Bschool of the country have a so called ââ¬Å"student bodyâ⬠or a ââ¬Å"student councilâ⬠which is an elected body of the student representative. They often take charge of organizing events in the school and work on several projects throughout the year. Its role in nurturing studentââ¬â¢s behavior and enhancing the developmental activities at schools is complementary. The student council is meant for the benefit of the students. The elected members of the council become the link between the students and the school administration. Often, school councils are involved in planning the yearly curriculum and are shouldered the responsibility of organizing various events in the academic year. This creates the opportunity to include topics of interest to the students and also conduct activities that complement student learning and make learning a fun experience for students. The students who involved with the student council develop several leadership and communication skills in the path of handling responsibilities shouldered for being a studentââ¬â¢s representative. On the other hand, the schools also stand to benefit from students councils. Firstly, the students take up the responsibility of organizing various events in the school, which would otherwise be an extra burden on the school administration, plus the studentsââ¬â¢ interest and involvement in the events are guaranteed. In some schools even the fund raising responsibilities are given to the students. But then we do not live in an ideal world ââ¬â is student council actually doing what it is supposed to do? In most cases, this council works in a lose-win mode. Either the college management makes the student representatives as puppets in implementing more and more non-student friendly ââ¬Å"rulesâ⬠or the student council decides on how to ââ¬Å"runâ⬠the college the studentââ¬â¢s way. Instead of being complementary the student council and college management often works so as to have the ââ¬Å"upper handâ⬠in decision making regarding the life at campus. Letââ¬â¢s look at it from the students point. Are we selecting the right people in the student council? Isnââ¬â¢t it a truth that in more cases than not we elect people who either has money power or muscle power to be in the student council ââ¬â much the same case as our politicians? Most often, students who can lobby win the posts rather than the people who actually deserve it. How many times have we felt that these people misuse their power for personal benefit and that a change is needed, but then who cares ââ¬â why should I get my hands dirty to improve the system? Isnââ¬â¢t my job just to get a good placement, flying grades and get over with my 2 years? College will survive on its own ââ¬â anyways it never cared about students! What most people fail to understand is that no college can ever grow without the efforts of management as well as students which should be complementary. No college event can ever be successful if both the stakeholders are not involved in its planning.

Quality Control Systems and Customer Satisfaction at Tesco
Quality Control Systems and Customer Satisfaction at Tesco TQM focuses on the ways in which these processes can be managed with two key objectives: 1 100% customer satisfaction 2 Zero defects Quality Management focuses strongly on the consequence of the relationship between customers (internal and external) and supplier. These are known as the quality chains and they can be broken at any point by one person or one piece of equipment not meeting the requirements of the customer. Failure to meet the necessities in any part of a quality chain has a way of multiplying, and failure in one part of the system creates problems elsewhere, leading to yet more failure and problems, and so the situation is exacerbated. The ability to meet customers (external and internal) requirements is vital. To accomplish quality throughout a business, every person in the quality chain must be trained to ask the following questions about every customer-supplier chain: Designed to give products that will satisfy our customers hope. The main considerations for listing Dairy products in Tesco are:- Safety All products must meet our microbiological standards throughout there shelf life. Quality The products must look great as well as taste delicious. Legality All legal requirements such as compositional standards and labeling must be met. Customer Focus Products will only be sold if there is a customer need for them and they deliver a fit for purpose solution. Produce standards ensure that all Tesco fruit, salad, vegetables and horticultural products have the highest standards of food safety and quality. They also address environmental considerations and labor standards. Produce Codes of Practice apply from production; from the selection of raw materials to harvesting and then packaging and distribution to Tesco stores They cover the design and maintenance of buildings and processing equipment including field rigs The welfare and training of personnel involved in the production process Environmental considerations within Natures Choice Tesco consults Industry Bodies, Professional Associations, Food safety experts and environmental experts to advise on all aspects of production. We also seek advice from with our suppliers and growers when agreeing what standards can be achieved. Natures Choice is an Integrated Crop Management System (ICMS) which has been running within the Tesco Produce Department since its conception in 1991. Tesco Natures Choice Ethical Standards Quality No one tries harder for customers Understand customers better than anyone. Be energetic, be innovative and be first for customers. Use strengths to deliver unbeatable value to customers. Look after people so they can look after customers. The target of cross-departmental survey considered some of the values which staff themselves wanted to see in Tesco: Values associated with customer service. Job satisfaction, Trust, fairness and integrity Open and honest communication teamwork, Quality standards Motivation Profitability Commitment Success and continual improvement The survey exposed that the Retail section came closest to reaching an ideal; Retail which had already been involved in programs to advance customer relations was followed by Head Office, and the Distribution section was in third place. Return surveys carried out show that each section has met or got close to the Main Boards original target. Meanwhile, the target has been stirred in line with their latest vision. The different sectors have maintained the programs in order to reach the new target and further develop their performance. TASK FOUR QUALITY PROGRAMS Quality Programs One of Tescos key business strategies on inward bound the Irish market in 1997 was to build close relationships with the Irish supplier-base to increase the amount of business with Irish suppliers producing Tesco own brand products and branded goods for stores in Ireland and for export to the UK and to the wider Tesco Group. Tesco Ireland put a 12-strong team of technical, quality and trade development experts in place to work with supplier companies construction their product development skills and market expertise, to help them prosper in a rapidly changing commercial environment. Over 130 companies have benefited from the program to date, including Bewleys, Country Crest, Dublin Meath Growers, and Glanbia, Gold star Meats, Irish Yoghurts, Lir Chocolates, Largo Foods and Shannon Minerals. These 130 agreed Irish suppliers of Tesco brand now supply over 1,000 food and non-food products to Tesco Ireland, and to the wider Tesco Group, including eggs, ham, rashers, beef, fish, milk, cheese, bread, burgers, bottled water, biscuits, ice cream, jam and the full range of Irish fruit and vegetables. Only 20 companies were permitted suppliers in 1997, before the program started. As a result of this program, and other support for Irish suppliers, Tesco now buys over Ãâ°1.5 billion worth of goods from some 800 Irish companies, over 80% of which are small to medium sized enterprises. Ãâ°400 million-worth of products are exported to Tesco in Britain annually. Supplier companies have created 1,025 new jobs as a result of improved business from Tesco. Tesco is now the largest Training and Development programs As an innovative and vigorous company in the highly competitive retail environment, learning and progression from within the company is core to our operation. Training forms a vital part of staff development, focusing on our key business priority of continually improving our service to customers. We support our people to accomplish their potential through access to specially-tailored training programs, and core skills workshops including effective meeting management, presentation skills, influencing, root cause analysis, personal efficiency and communication skills. All staff has regular performance reviews with their managers and agrees personal development plans (PDPs), setting clear personal performance objectives. This ensures that all staff has the right skills to do their jobs. Supply Chain Labor Standards It is aim to act responsibly in our commercial and trading activities. The welfare and safety of the employees of our suppliers is vital. It expects all our suppliers to extend fair and honest contact to their employees and to all with whom they do business. We have developed a new course for our technical managers to raise their awareness of ethical issues and worker welfare in the supply chain. We will continue to train all new technical managers in this way. Managing standards across our large and complex own brand supply base is a challenge, but Tesco is committed to working with our suppliers to maintain, develop and improve standards. Benchmarking Compliance with all components of the key elements will lead to support of a submitted standard through the Initiative framework and subsequent getting by retailers. Once a food standard has been benchmarked successfully, the standard is acknowledged. The conforming benchmarked food safety standard can be applied by food suppliers throughout the whole supply chain, upon agreement with retailers, when defining contracts for sourcing of products. The application of the benchmarked standards to particular products will be at the maturity of retailers and suppliers. Staff feedback Buyer of Irish food in the world Viewpoint is Tesco Irelands annual staff survey, which provides all employees with a channel for communicating their views and opinions, and informs company management on how things could be done better and simpler for staff. Areas privileged include: emotional loyalty, satisfaction with current role and manager and clarity of role purpose alongside level of satisfaction with career progression, pay and benefits as well as general demographics. Each line manager receives a report on their teams overall responses, and they then work with the team to address areas which the survey has highlighted as requiring attention. Over 90% of staff contributes to Viewpoint surveys. In addition to providing a means to holding Tescos high standards together, the Tesco-Verax programs are probable to produce other benefits which include: Helping staff give a better service to the business. More substitution between departments as people make better use of their individual skills.

Drama Performed to Others :: Drama
Drama Performed to Others Our drama group was given the task of introducing a year nine class to the play 'Macbeth'. Apart from the obvious, there were five themes in the play that the group as a whole thought needed exploring: insanity; good versus bad; the supernatural; guilty conscience; and murder. We looked into each of these topics individually and decided on how we could include them in our final performance, in each lesson we learned more and more about both 'Macbeth' and the skills needed to teach a younger year group the basics of the play. We decided that the first thing that needed to be learned was the creation of atmosphere on stage. We did this by lowering the lights, putting just a candle in the centre of the room, and playing the sound effect of rain and howling gales. We each had to find one word that summed up the 'feeling' in the room. The key words that came up were remembered throughout our development of the piece of drama and we tried to capture these feelings on stage. Keeping in role and developing a convincing character was essential for the task and I learned this over the period of time building up to our final performance. We had decided to show five still-images to the year nines and, along with a narration, tell the story as an introduction. In groups we picked out the five points that seemed most significant: the meeting of the witches on the heath; the 'persuasion' scene (between Macbeth and Lady Macbeth); the banquet scene; the second witches scene (the premonitions); and the scene where Macduff finally kills Macbeth. In these groups we performed the still-images and showed what each character was thinking through thought-tracking, which added depth to the image. In pairs we performed our own versions of 'the persuasion scene', with one playing Macbeth and one playing Lady Macbeth. Through manipulation, Lady Macbeth always beats Macbeth one way or another, and we learned to create the right mood on stage, this improvisational work helped develop characterisation. After discussing the scene we were to study (the 'banquet scene' [Act Three, Scene Four]) and read through the original script, we began improvisation of a modern-day remake of the scene. Our class decided to work in just one group and we were sure we wanted to bring the scene to a modern-day setting so we could come up with our own interpretation. As a group we had to decide on who the Macbeth of the 21st century would be, and came up with plenty of suggestions. The one we finally decided on was a night-club owner, the night-club

A Young Womans Fantasy in The Turn of the Screw Essay -- Henry James
A Young Woman's Fantasy in The Turn of the Screw à à à The Turn of the Screw, by Henry James, is an odd story about a young woman who, leaving her small country home for the first time, takes a job as a governess in a wealthy household.à Shortly after her arrival, she begins to suffer from insomnia and fancies that she sees ghosts roaming about the grounds.à James is a master story-teller and, at times, the complexities of the story make it difficult to follow.à The Turn of the Screw is a story within a story, the tale of the governess being read aloud as a ghost story among friends.à Harold C. Goddard wrote a fascinating piece of criticism entitled "A Pre Freudian Reading of The Turn of the Screw."à When applied to the book, his theory makes perfect sense.à Goddard suggests that the governess, young and inexperienced, immediately falls in love with her employer during their meeting.à As a result of her unrequited love, her overactive mind creates a fantasy in which the the two ghosts intend to harm the children, in order to make herself a heroine, thereby getting the attention of her employer. à à à à à Goddard points out that the young woman is unstable from the beginning.à We find out little about her background, except that she is "the youngest of several daughters of a poor country parson" (4).à It becomes immediately obvious to the reader that such a drastic change of environment as she experiences is cause enough for her to experience extreme anxiety.à Indeed, she tells Mrs. Grose, "I'm rather easily carried away.à I was carried away in London!"

Before the Volcano Erupted: The Ancient Cerén Village in Central America
The archaeological site of Joya del Ceren, located in the broad Zapotitan Valley in the fertile region of western El Salvador, is a remarkable and important find that has been compared to the ancient ruined cities of Pompeii and Herculaneum in Italy. Like Pompeii, Joya del Ceren was preserved under layers of volcanic ash in the catastrophic Loma Caldera eruption from the nearby Ilopango volcano approximately 600 AD. This eruption forced the sudden abandonment of the site by its inhabitants who were forced to leave their possessions behind.Dr Payson Sheets of the University of Colorado-Boulder has been leading the excavations of the site, and as this ancient farming village of the Maya is now being revealed, many important insights into the household and community life of the ancient Maya, as well as their economic, social, and religious activities are becoming better understood. In Dr. Sheetsââ¬â¢ book, Before the Volcano Erupted: The Ancient Ceren Village in Central America, an o verview of the knowledge gained by recent excavations is provided.The book opens with a discussion of volcanology, geophysics, and paleobotany. It is clear that the presence of the nearby volcanic hills around the site presented both benefits and hazards to the ancient inhabitants. The volcano provided a source of hard stones for making manos and metates, its ancient eruptions deposited a fertile bed of ash for fruitful agriculture, but it also proved the destruction of their village.What is so amazing is the fine state of preservation that the volcanic eruption gave to the material culture of the site. The buildings, complete with their thatched roofs (mice included) and painted walls, the beautifully painted gourds and pottery vessels, whole and filled with foodstuffs, liquid residues, utensils and other personal items, the craft tools, and the clear evidence of craft production are all on hand, looking untouched despite their fourteen centuries of age. Consider this remarkable st atement:ââ¬Å"The numerous seasonally sensitive plants preserved at the site indicate the eruption probably occurred in August. Further, the positions and conditions of artifacts indicate the eruption probably occurred in the early evening, after dinner was served but before the dishes were washed, likely between 6:00 and 7:00 P. M. â⬠(Sheets) For all the fury and destruction that volcanoes can cause, such an outcome is nevertheless a joy to historians and archaeologists, and should be to anyone curious about the lives of prehistoric peoples.The focus of the explorations at Joya del Ceren is centered on ââ¬Å"Household Archaeology,â⬠with the household being defined as ââ¬Å"the domestic coresidential social and adaptive unit intermediate between the individual and the neighborhood. â⬠(Sheets) Part II of the book describes the four households excavated prior to publication, with eleven building having been completely excavated, and seven others partially excavate d. Professor Sheets summarizes the work to date as follows:Four buildings of Household 1 have been excavated, including a domicile (for sleeping, eating, and various daytime activities), a storehouse, a kitchen, and a ramada-style building that occasionally was used for chipped stone tool maintenance, among other functions (Structures 1, 6, 11, and 5, respectively). Two buildings of Household 2 have been excavated, the domicile and the storehouse (Structures 2 and 7). The kitchen has yet to be excavated, and we do not know if Structure 18 is a part of this household.Only a part of the kitchen of Household 3 is known (Structure 16). The storehouse of Household 4 has been excavated, and it is a storehouse and much more (Structure 4). The maguey (Agave americana) garden south of the building produced fiber for about a dozen households; the leaves were depulped to liberate the fibers using Structure 4's northeast corner pole. â⬠(Sheets) The results of these excavations revealed a good deal about household and village life of the people of the Maya frontier circa 600 AD.We have an expanded view of what they ate (maize, beans, chiles, squash, manioc, maguey, cacao and guayaba among others), the wealth they possessed (over 70 vessels in household 1 alone), and their source of livelihood (both subsistence farming and craft specialization). Indeed it is possible to speculate that each household produced a certain type of finished craft for export trade within or beyond the village.Sheets describes how ââ¬Å"each household overproduced at least one craft or commodity and used that for exchange within the community and to obtain long-distance traded items that generally were produced by specialists, such as obsidian tools, hematite pigments, and jade axes. â⬠(Sheets) It is shown how household 1 produced groundstone items such as manos and metates, and a tool called a donut stone. Household 2 likely served as a painted gourd factory, as evidenced by the prese nce of cinnabar paints and the use-wear on chipped stone tools found at the site.In addition to the household structures, some other community buildings have been identified. These include Structure 9, a large sweat bath that could accommodate a dozen people , structure 10, considered to be a religious festival building of some kind, as evidenced by the presence of some sacred artifacts, such as a deer skull headdress, and an obsidian blade with traces of human blood. There is also a large community center or civic complex, perhaps used for local government functions or religious purposes or both. The religious buildings were painted white and are the only white buildings found at the site.Some of the agricultural fields have been examined, and the results are very interesting. For example, the rows for maize were ridged, and some areas show where portions of the crop have already been harvested and the ground replanted with the second crop for the year. Many species of plants are i dentified by plaster casting, including ââ¬Å"maize, beans, chiles, squash, manioc, maguey, various trees such as cacao and guayaba, and a number of palm and deciduous trees. â⬠(Sheets) The manioc field is known as the first evidence of the cultivation of this crop in the Americas.In a recent CU-Boulder news release article, Sheets said ââ¬Å"we have long wondered what else the prehistoric Mayan people were growing and eating besides corn and beans, so finding this field was a jackpot of sorts for us. Manioc's extraordinary productivity may help explain how the Classic Maya at huge sites like Tikal in Guatemala and Copan in Honduras supported such dense populations. â⬠The work at Joya del Ceren is far from over. The book explains how the archaeologists are using ground penetrating radar equipment to locate numerous other buildings for future excavations.As time goes on, the riches of Joya del Ceren will continue to emerge from the ashes. Before the Volcano Erupted: The Ancient Ceren Village in Central America is a rather typical archaeological report, fairly dry for reading, but full of fascinating information if you take the time to pick through it. What is important is what the Archaeology of the site can teach us of the ancient people that lived there. The site must be an outstanding place to visit, for to see such well-preserved artifacts would surely spark the imagination.I would surely recommend the book to anyone interested in the Maya, in archaeology and history in general, or to anybody that is curious about the way that ordinary people from the past may have lived their lives.

Realization from the film Murielââ¬â¢s Wedding
Murielââ¬â¢s wedding is a tragic-comedy film written and directed by P.J Hogan. This Australian film conveys various aspects related with change.à The main concepts of change seen from this movie are change in perspective and in attitude within the persona, ensuing from the understanding of whom you are and how to get there. Muriel's wedding reveals these concepts through Muriel's discovery of herself, and realizing that real life still continue to possess different trials that needs be overcome in order to achieve real growth. Muriel Heslop, a hopeless romantic, overweight girl who lives in Porpoise Spit, Australia, with her parents and four siblings. Muriel lives her life in the fantasy world of Abba song and dreaming about getting married. She thinks that getting married is the best way for her to find the perfect happiness. Muriel's character is not that positive. She has a low self-esteem and she looks herself as useless being. She lies, she steals and even tries to change her own identity, but in the end, she realized that all the things she had done would not give her the happiness her looking for. Muriel life in Porpoise Spit is miserable. Her relationship to her family is quite undesirable. Bill Heslop, Murielââ¬â¢s father, is a corrupt politician who is completely despicable man. He always tries to impress people with his connection and still manage to find his time to degrade his family. His slogan ââ¬Å"You Can't Stop Progressâ⬠but he manages to stop the progress of everyone in his family, by labeling them as useless and embarrassment, except for Muriel. On the other side, Betty, Murielââ¬â¢ mother, a painstakingly frightened woman who is treated by her children l and husband like a slave. Like Muriel, her mother was also arrested for stealing. Betty looked to be very lonely and unattached to reality herself because she gets all the blame from Murielââ¬â¢s father for Muriel stealing their money. Betty died, a speculated suicide, after Murielââ¬â¢s father wants to have a divorce to live with someone he is having an affair. Both Muriel and her mother appeared to have a lot in common as far as the ability to separate their selves from reality. Another major character in the film was Rhoda, an old friend of Muriel from school that she meets on the trip. They both to get along with each other, then, Muriel realized that now she has more confident in herself and found someone who can call her a real friend. Rhoda has her own problem, she has a cancer and confined on a wheelchair and having her own crisis identity. Although Muriel and Rhoda are always having fun, still Muriel is unhappy because she really thinks that getting married will give her the prefect happiness. So, with the help of Rhoda, Muriel change her identity by changing her name to Mariel. Then, eventually, she got married to an Olympic swimmer who only needs to have an Australian passport. Muriel think that she got the best option because she thinks that sheââ¬â¢s hitting a bird in one stone, living in her fantasy of being a bride and wife and at the same time getting money to pay her father back. This perception of Muriel is like a ââ¬Å"falsification of viewâ⬠; that being a wife is all that she needs because her parents will also be happy, and at the same time, she can live her friend. But when Murielââ¬â¢s mother died, she came into realization that everything sheââ¬â¢ve done really doesnââ¬â¢t give her the happiness she is looking for. She also realized that she never loved her husband at all. She wants to stop lying. She donââ¬â¢t want to ââ¬Å"Marielâ⬠anymore which she created when she was in Sydney. She ended up finding again her happiness in Sydney by helping her friend, Rhoda. She too helped her father realize the mistakes he had made with them. All these she did through discovering her identity (happiness). She no longer needed to be ââ¬Å"Marielâ⬠, Muriel found herself, Muriel. She was always there inside herself not knowing she was inside because she was just too busy looking inside of her fantasy world.

A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions(including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.[3] Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves. Tsunamis generally consist of a series of waves with periods ranging from minutes to hours, arriving in a so-called ââ¬Å"wave trainâ⬠.[4] Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous and they can affect entire ocean basins; the 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history with over 230,000 people killed in 14 countries bordering the Indian Ocean. The Greek historian Thucydides suggested in his late 5th century BC, History of the Peloponnesian War, that tsunamis were related to submarine earthquakes,[5][6] but the understanding of a tsunamiââ¬â¢s nature remained slim until the 20th century and much remains unknown. Major areas of current research include trying to determine why some large earthquakes do not generate tsunamis while other smaller ones do; trying to accurately forecast the passage of tsunamis across the oceans; and also to forecast how tsunami waves would interact with specific shorelines. A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore. Tsunami are waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean. Earthquakes Most tsunami are caused by large earthquakes on the seafloor when slabs of rock move past each other suddenly, causing the overlying water to move. Theà resulting waves move away from the source of the earthquake event. Landslides Underwater landslides can cause tsunami as can terrestrial land which slumps into the ocean. View our landslide generation animation which demonstrates how a landslide induces a tsunami. Volcanic eruptions Less common are tsunami initiated by volcanic eruptions. These occur in several ways: destructive collapse of coastal, island and underwater volcanoes which result in massive landslides pyroclastic flows, which are dense mixtures of hot blocks, pumice, ash and gas, plunging down volcanic slopes into the ocean and pushing water outwards a caldera volcano collapsing after an eruption causing overlying water to drop suddenly. An earthquake is the shaking of the earth that occurs after pieces of the crust of the Earth suddenly shift. The term earthquake describes the sudden slip on a fault and includes the ground shaking and radiating seismic energy that is caused by the slip. Volcanic activity, or other geologic processes, may cause stress changes in the earth that can also result in an earthquake. Earthquakes can occur anywhere in the world although some areas of the globe are more likely to experience an earthquake than others. Earthquakes occur in all types of weather, in all climate zones, in all seasons of the year, and at any time of day making it impossible to predict with any certainty when an earthquake is likely to occur. The best seismologists (scientists who study earthquakes) can do is to look at the historical record of earthquake activity for any geographical area and use this data to calculate the probability of an earthquake occurring in the future. Earthquake prediction is still in the future. A tsunami is a series of sea waves that can be caused by earthquakes or landslides at or beneath the sea floor. The displacement of the sea floor that occurs during certain large submarine earthquakes and landslides causes displacement of large volumes of the sea water above it producing large, fast moving waves. When a coast line experiences a tsunami it can be due to an earthquake near the coast or due to a quake occurring in a distant part of the ocean. Coastal areas may experience little or no damage from anà earthquake but can be devastated by the resulting tsunami. 2010 Haiti Earthquake Haiti suffered one of the largest earthquakes in more than 200 years in 2010. The 7.0 magnitude earthquake was centered about 10 miles from Port-au-Prince and set off a swarm of tsunamis that killed three people and destroyed several homes. The waves were averaged to be about 10 feet high. 2010 Sumatra Earthquake/Tsunami he October 2010 Sumatra earthquake occurred on the same fault as the 2004 Indian Ocean earthquake. The second time wasnââ¬â¢t as disastrous but there was still substantial damage. This time around the earthquake was 7.7 on the Richter scale and developed a tsunami that struck the Mentawai Islands. The tsunami, which had a wave of 9 feet, destroyed many of the villages on the island. It displaced more than 20,000 people and reportedly killed 435. 2010 Chile Earthquake/Tsunami A 8.8 magnitude earthquake struck Chile on February 27, 2010 with intense shaking that lasted for about three minutes. It triggered a tsunami that destroyed several coastal towns in south-central Chile. The tsunami raced through the Pacific Ocean that 53 countries had to post warning, though there was little damage as it moved past Hawaii, Australia and Japan. The death toll was 521 victims. 2011 Tohoku Earthquake/Tsunami The 9.0-magnitude megathrust earthquake that hit the Tohoku region of Japan on March 11, 2011 was the largest earthquake to have ever hit the country. Japanese Prime Minister Naoto Kan even called it ââ¬Å"the toughest and most difficult crisis for Japanâ⬠since the end of World War II. The tsunami that traveled along the Pacific coast of Japanââ¬â¢s northern islands was measured to be at least 9.8 feet high. Entire towns and cities were swept away and about 5,692 are said to be dead, with 9,522 missing and 2,409 injured. 1771 Great Yaeyama Tsunami On April 24, 1771, the Yaeyama Great Earthquake caused the formation of the 1771 Great Yaeyama Tsunami. The tsunami hit both the Ishigaki and Miyakojima Island of Japan and killed a total of 12,000 people. Agriculture was severely damaged and the population decreased about one-third of what it was. The tsunami at Ishigaki reportedly reached a height of 262 feet. 1792 Mount Unzen The 1792 eruption of Mount Unzen in western Kyushu, Japan is the most deadliest volcanic eruption ever in Japan. It caused a megatsunami that reached up to 330 feet and killed 15,030 people. 1896 Meiji-Sanriku Earthquake The 1896 Meiji-Sanriku earthquake hit Japan on a day when the country was celebrating both the return of soldiers from the Sinto Japanese War and a Shinto holiday. The 7.2 magnitude earthquake that took place was small but the tsunami that struck the coast of Sanriku 35 minutes later was much greater. Waves as high as 125 feet were measured and nearly 9,000 homes were destroyed. 22,070 were reported dead and an unusually high count of victims with fractured skulls and broken or missing limbs. Hawaii also suffered some destruction from the tsunami as waves of 30 feet were measured there. 1868 Arica Earthquake/Tsunami The estimated 8.5 to 9.0 magnitude earthquake near Arica (then part of Peru, now part of Chile) in 1868 nearly destroyed all of Arica and its surrounding cities. The tsunami it produced almost completely destroyed the port city of Pisco. It also caused some damage in Hawaii, New Zealand and Japan. About 25,674 casualties were reported. Aug. 27, 1883: Eruptions from the Krakatoa volcano fueled a tsunami that drowned 36,000 people in the Indonesian Islands of western Java and southern Sumatra. The strength of the waves pushed coral blocks as large as 600 tons onto the shore. June 15, 1896: Waves as high as 100 feet (30 meters), spawned by an earthquake, swept the east coast of Japan. Some 27,000 people died. April 1, 1946: The April Fools tsunami, triggered by an earthquake in Alaska, killed 159 people, mostly in Hawaii. July 9, 1958:Regarded as the largest recorded in modern times, the tsunami in Lituya Bay, Alaska was caused by a landslide triggered by an 8.3 magnitude earthquake. Waves reached a height of 1,720 feet (576à meters) in the bay, but because the area is relatively isolated and in a unique geologic setting the tsunami did not cause much damage elsewhere. It sank a single boat, killing two fishermen. May 22, 1960: The largest recorded earthquake, magnitude 8.6 in Chile, created a tsunami that hit the Chilean coast within 15 minutes. The surge, up to 75 feet (25 meters) high, killed an estimated 1,500 people in Chile and Hawaii. March 27, 1964: The Alaskan Good Friday earthquake, magnitude between 8.4, spawned a 201-foot (67-meter) tsunami in the Valdez Inlet. It traveled at over 400 mph, killing more than 120 people. Ten of the deaths occurred in Crescent City, in northern California, which saw waves as high as 20 feet (6.3 meters). Aug. 23, 1976: tsunami in the southwest Philippines killed 8,000 on the heels of an earthquake. July 17, 1998:A magnitude 7.1 earthquake generated a tsunami in Papua New Guinea that quickly killed 2,200. Dec. 26, 2004: A colossal earthquake with a magnitude between 9.1 and 9.3 shook Indonesia and killed an estimated 230,000 people, most due to the tsunami and the lack of aid afterward, coupled with deviating and unsanitary conditions. The quake was named the Sumatra-Andaman earthquake, and the tsunami has become known as the 2004 Indian Ocean tsunami. Those waves traveled the globe ââ¬â as far as Nova Scotia and Peru. March 11, 2011: A massive 8.9-magnitude earthquake struck northern Japan, triggering tsunamis that reportedly swept up cars, buildings and other debris. The Japan Meteorological Society has forecast more major tsunamis in the area, with some expected to reach more than 30 feet (10 m) off the coast of Hokkaido, Japanââ¬â¢s second largest island. A tsunami was also generated off the coast of Hawaii, one that could cause damage along the coastlines of all islands in the state of Hawaii, according to the Pacific Tsunami Warning Center. Tsunami warnings are in effect across Hawaii as well. 2004 Indian Ocean earthquake & Sanaysay. (2016, May 26).
