Moreover, when looking at Geertz book Religion as a Cultural System Geertz paid more attention to the ways in which religion is articulated, how religion connects with the spiritual aspects and sorcery, his definition of religion is that Religion is a system of symbols which acts to establish powerful, pervasive and long-lasting moods and motivations. Religion is mostly used in ways that it paints a picture of how a person should live and the way things really are, everyone has specific values that they hold but it might differ from another individuals morals and value they hold. Each person performs religious practices differently but the interpretation of religion is the one gets everyone confused. For example the Indigenous view dream time as a religion where they sing and write stories for generations, witchcraft and sorcery might also be viewed as a religion to some people and then we have Islamic, Christianity and science, which people also beliefs and that belief might have a certain affect on them including their prospective of how they view the world. We will write a custom essay sample on Moreover, when looking at Geer or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page As Greetz mentioned Some of the most important effects of the religious perspective come through a redefinition of our daily life in life of religious perspectives (Geertz 1973, clothing perceptions†¦pp. 24-35).Additionally, In comparison to Linda H. Connor and Geoffrey Samuels book Healing Powers and Modernity focuses more on the indigenous healings and Islamic perception of sorcery. He believes that many people luck proper education in Indonesia therefore are unaware of western healings compared to the mens who are educated. The connotation of illness still largely constituted through social relations that have persisted from one generation to the next. Sorcery has a continuity of meaning from pre-Islamic times to the present because it has always provided an explanatory link between illness and ever-present strains in village social relationships. From the villagers point of view, local variants of biomedicine are part of state-promoted modernist discourse. Until such time as a different engagement with the date evolves through redistributions of power and knowledge, rural people will continue to favour those healing resources that are given to them and that could involve sorcery in other hand sorcery can easily be accessed to compared to western medicine due to the cost of medication while traditional healing is less expensive or might even be free depending on agreement, which are embedded in the social field of the village.Healing and power in Indonesia are formed into two medical systems, which are the biomedicine and indigenous medicine. The, Elah villagers have access to both. The Indigenous healings are made through body customary medical practices performed by numerous skilled Belian. The curing practices of Belian originated in the Waktu Telu religion. There are approximately thirty seven Balinese people who lives in the Elah village, mostly in their forties and older. When illnesses or diseases occurs in that village, it is u sually treated through different magic practices such as teeth treatment, illnesses, deliverance of babies, producing love magic and sorcery, (Hunter 2001). Even though there is other safer ways to delivering baby apart from using magic the Belian still choose to do sorcery because they believe it works better and most people feel that its cheaper to access. In regards to John P. Taylors book, he describes Nakaemas, which is another word for sorcery/witchcraft in the Vanuatu society to be resonated in an everyday life of people in Vanuatu. Nakaema is not defined as broader practice of magic that involves discussions of sorcery or witchcraft in the academic literature but rather a wicked practices that is seen mostly in the North Efate, some of the practices includes poisoning, bodily possession, transforming people into certain animals such as Dogs and sometimes transforming them into devil itself, they control human body and mind and even death can occur through Nakaemas. Throughout the text Taylor had mentioned that victims are usually attacked due to jealousy, wealth, gossips and ownerships. He believes that those practices are a com bination of the moral, physical and sacred sacred force.Furthermore, the anthropologists believe that when taking a spiritual belief one has to search and know which agency they are from and who it affects. They believe that humans are both the sources and bearers of agency, individual such as politicians, lawyers, and presidents also undergo self-protection and secure themselves from the forces attacks of witchcraft; those protections are done through a spiritual healers called Klevas who uses multiple traditional medicine such as plants and other healing practices to protect the individuals from witchcraft. Klevas also helps reveal the causes done by Nakaema, protect people from a curse and also bring an end to a curse and other form of Nakaemas power. (Taylor 2015). Taylor describes Kleva as the human interaction between sacred power of Christianity and sorcery with the combination powers of black and white magic.

Grave, Gravy, and Gravity

Grave, Gravy, and Gravity Grave, Gravy, and Gravity Grave, Gravy, and Gravity By Mark Nichol Are grave, gravy, and gravity related? Though they could be interpreted to have associated senses, their etymological origins are distinct. The noun grave, referring to a burial place, may seem to refer to weight, but it is unrelated to gravy or gravity, as is its derivative engrave. Grave and engrave stem from the Old English term grafen, meaning â€Å"dig† or â€Å"chisel†; the latter word, describing the action of inscription in stone or another hard surface, is a later form of the obsolete verb grave, which meant â€Å"carve.† And though gravy, a sauce based on the juice of cooked meat, can be heavy, its French forebear, grave (also graue), is apparently a misspelling of graune, meaning â€Å"sauce† or â€Å"stew†; its origin is the Latin word granum, meaning â€Å"grain† or â€Å"seed.† (Gravy can also mean, by extension, something good that was not earned or expected, such as effortlessly acquired funds, hence the idiom â€Å"gravy train† for a source of easy money.) Meanwhile, gravel comes from the Old French word gravele, which pertains to sand or small stones. But gravity is weighed down by a family of words, a couple of them perhaps unexpected, that have as a common ancestor gravis, meaning â€Å"heavy.† One of them is the sister noun gravitation; the sense distinction is that gravity refers to weight or to downward acceleration, which consists of centrifugal and gravitational, or attracting, forces. The verb form gravitate has a scientific meaning of â€Å"exert weight† or â€Å"move downward† but has also acquired the sense of emotional attraction or philosophical tendency; one might be said to gravitate toward a certain personality type or a specific school of thought. Other terms include the adjective grave, meaning â€Å"solemn,† gravid, meaning â€Å"pregnant† (from the notion of the pregnant state as a heavy burden), and gravitas, which means â€Å"dignity,† â€Å"influence,† or â€Å"presence† and alludes to a person’s serious attitude or physical bearing. Two words whose kinship with these words and each other may not be apparent are aggravation and grief. The original meaning of aggravation is â€Å"the act or result of making something worse.† It has another sense, â€Å"irritation,† which dilutes the useful specificity of the earlier definition but is also hundreds of years old. Grief, meanwhile, is also descended from gravis. Its meaning, â€Å"suffering,† stems from an Old French word (spelled the same) meaning â€Å"injustice† or â€Å"misfortune.† One who experiences grief is said to grieve, although the term can also apply to anger or oppression, especially in the verb form aggrieve, and one who is aggrieved is said to have a grievance. (That word may also apply to a statement articulating one’s dissatisfaction.) The adjectival form, grievous, means â€Å"difficult† or â€Å"serious.† Meanwhile, the term gravamen refers to the gist, or focus, of a grievance, especially in legal contexts, in which it pertains to the grounds for a legal action.

Analyzing and Comparing the Mise-en-scene of David O'Russel's Three Essay

Analyzing and Comparing the Mise-en-scene of David O'Russel's Three Kings to Steven Spielberg's Saving Private Ryan - Essay Example David O’Russell knew the power of setting a story during the time of war, thus he came up with the most finely tuned, eccentrically conventional film Three Kings. Both Saving Private Ryan and Three Kings have effectively shown war in a resolute way that serves similar aims but achieves this in different manners. O’Russell’s Three Kings clearly uses the narrative device of an ethical story to relate the Gulf War’s moral lessons as well as to rewrite America’s ethical position over the people of Iraq through revising what was viewed as a moral defeat. The film tells a narrative of a gang of four U.S fighters on operations at the Gulf at the end of the dispute as they find out a map to one of the secrete bunkers of Saddam Hussein, containing huge amounts of Kuwait gold, and plan to steal it for their own gains. On the other hand, Steven Spielberg has been criticized for failing to employ narrative action basing on the moral and national purpose in his film Saving Private Ryan. This criticism can be understood in the perspective of the constraints placed on modern cinematic stories of war by the Vietnam syndrome (Andersen 193). Even though Three Kings is developed around a definitely American-based fictional plot, this film typically aims to bring in issues concerning Iraq and addresses it to a certain extent as the film develops. On the other hand, Saving Private Ryan tries to reillusion American national distinctiveness in the wake of Vietnam by presenting a more distant past. The specific ethical justification for starting war and admitting its sacrifices and horrors is found in ethical campaigns against the Nazi plot of Holocaust. Through stitching the Holocaust into the movie, the film takes part in ‘Americanization’ of a memory of Holocaust, avoids Vietnam as a source of distressing memory, produces a redemptive national uniqueness, and constructs a moral usable past in the present. In both films, the use of ima gery has been clearly utilized. Saving Private Ryan starts and ends with a shot of a flag that is faded and desaturated of color. The red colors have turned to pink, white to gray, and the blue colors have lost their color completely. The flag is transparent, moving forth and back in the centre of a cool dusk as the sunlight penetrates straight through it. The reason behind this is that the flag symbolizes a lost time and a fading generation. The American elites who fought to keep such banners were gone and the film was developed for their sake. Such features show that Saving Private Ryan may be the greatest film ever produced about horror and heroism in war situations. It shows how heroic conduct can be unusually difficult, impulsive, lucky, instinctive, and deliberate, all at once. In contrast, Three Kings had mixed receptions on its release. In general, reviews involved praise for technical elements of the film as well as criticism of the way the Gulf War was presented. In the Wa shington Post, Stephen Hunter claimed the style of the film had the feeling second to none, as it re-imagines the past war movie post-modernly. He further concludes that the film was ideologically unremarkable. Similarly, Three Kings uses some sort of imagery in the storyline. At the start of the scene, a discussion goes on between Major Gates and his Staff Sergeant, standing near a helicopter. The image of a helicopter was used as an icon in this film, though not frequently used outside the scene (Andersen 194). At the beginning, when a shot cuts through, it is obvious that the positioning of the characters is to enable the blade to remain at the heart of the screen, right between the

How the war on terrorism affected the way of life in Afghanistan Research Paper

How the war on terrorism affected the way of life in Afghanistan - Research Paper Example The horrific terror attacks elicited a mixture of economic, political and social reactions globally. Anti-Islam and hatred discourse that failed to separate the ordinary Muslims from the despotic, militant terrorists was rife all over. Issues of distrust between Christian and Muslim communities led to increased antagonism and in some instances extremist tendencies. For example, in the West, incidences of Muslim beatings and at times killings were reported. Examples of Muslim extremist tendencies were evident through support of the terrorist activities. Following the 9/11 attacks, it was quite clear that a retaliation response by the American government led by George Bush was eminent. To this end, the greatest fear pertained to what form of retaliation, how it would be enforced and also the potential impacts on the ordinary lives of the Afghan citizens. The impacts on the Afghan citizenry were also being assessed in consideration that they were still suffering at the behest of the Tal iban regime. In the period leading to 9/11, the Bush administration had been subject to scathing criticism for its position on various policy issues locally and internationally. These issues ranged from, geopolitics, environmental, economic, defense, inequality among others. However, the ghastly terror attack of September 11 resulted to considerable reduction of criticism towards the Bush administration. On the contrary, support for the Bush administration in light of the terror attacks began to rise significantly. This support was as a result of the announcement of the retaliatory action that the American administration would embark after the terror attacks. To this end, on 20th September, 2001, President George Bush made a televised address in... Conclusion The war on terrorism that began in earnest over a decade ago, has clearly caused profound impacts. These impacts cut across the divide of both pro and anti crusaders of terrorism. To this end, the long protracted war has not only impacted countries targeted for terrorism networks, but also the primary opponents of terrorism such as the United States. Following the September 9/11 attacks, it is clear that the geo-political, economic and social spheres changed dramatically for all actors. In light of the United States, the change of stance pertaining to foreign policy in dealing with terrorism dramatically changed to a military offensive against any threat to its security. Furthermore, the social fabric pertaining to relations among diverse religions was visibly tested. In addition, the astronomical cost of funding the war presented another significant burden on the American citizenry as well as local political intrigues involving pro and anti war protagonists. However, one vital aspec t that did not receive adequate attention was the assessment of impacts on the ordinary Afghanis citizens. Evidently, much attention has been focused on America and their justification for the war on terror without due consideration to the Afghani citizenry.

Chilean miners Research Paper Example | Topics and Well Written Essays - 750 words

Chilean miners - Research Paper Example Firstly, the mode of communicating the message about this horrifying incident must be face-to-face as after receiving this news, the families of the victims would need instant physical support and care. Furthermore, in order for the families to stay strong and not lose hope, the news must be broken to them in a manner that helps them in reassuring their selves that nothing terrible is going to happen. For this, it is highly significant for the news breaker(s) to paraphrase their message considering the expected response from the family members after getting the news i.e. the message must include what the rescue workers are capable of doing in order to help the trapped men. Moreover, it is also very important for the people who are going to deliver the message to have patience and to be available as much as possible for the families. It is essential because as soon as the family members will receive this news, they will come up with a variety of questions regarding the safety and well being of their loved ones who are trapped underground and they will be looking forward to the people involved in this matter (the company authorities, rescue workers, the government of Chile, etc.) for all their questions to be heard and answered properly. Many a times when such incidents happen, it has been observed that the people who are responsible for providing endless support to the family members of the victims try to escape from the situation only so that they will not have to answer each and every question that is being asked and also because they have a fear of being accused to be responsible for the incident. Unfortunately, such acts contribute in worsening the already awful state of the victims’ families as all they need during such hard times is to have people around them to cater their worrisome anticipations, such behavior should be strictly avoided. Furthermore, it is also necessary to enlighten the family members regarding the facilities such as drilling narr ow holes up to the level through which air, food, fluorescent lights with timers, games, and other helpful necessities can be supplied down to the trapped men along with exchange of messages (â€Å"Trapped in a Chilean Mine†, 2010) in order to help them survive inside the darkness; which the rescue workers are able to competently provide as this will be helpful in bringing and strengthening the hope in the hearts of families. Moreover, keeping the families up to date with the progress of rescue work is another vital factor to be kept in mind but care should be taken in order to steer clear of giving any kind of false hopes as these would only make the loss, if any, more unbearable to the families at the end. Another important measure to be taken is that of providing professional help of psychologists to the families who are going through this difficult time. It is important for keeping them in healthy mental states (â€Å"Trapped Chilean Miners†, 2010) so that they can learn different coping strategies to survive in this stressful time and also can prepare themselves to accept and deal with whatever is hidden for them in the near future. An added help to cater the needs of the suffering family members would be that of telling them the real stories of successful survivors of similar incidents. What would be the potential needs of the company’s employees when receiving a message about this incident? As in the case of breaking the news to the family members of the trapped men, it would be better if the employees of the company are also given the message about this incident face-to-face instead of using any other mode of communication. It is important because while giving out such sensitive messages, it is always better for the person giving the message to be able to observe the reactions (both verbal and non-verbal) of the message receivers in order to be able to modify the tone and delivery

Reaction Time And Energy Drinks

Reaction Time And Energy Drinks This extended essay is an investigation into reaction times in males and females and how they were affected by Red Bull. The research question was How significant is the reduction in reaction time due to drinking Red Bull, in males as compared to females between the ages of 16-17. To answer this, a simple experiment was carried out to obtain the necessary data. The ruler drop test was conducted using a group of 20 subjects (10 male and 10 female). The reaction times of the subjects before and after drinking Red Bull were then calculated using the results from the ruler drop test and the formula t = à ¢Ã‹â€ Ã… ¡(2d /a). The mean data was then analysed using the T-Test to see how significant the difference in reaction time was before and after drinking Red Bull. This revealed that even though reaction times in males reduced after consumption of Red Bull, the reduction was not significant. Female subjects showed greater decreases in reaction time after drinking Red Bull even though on average their reaction times were slower than male reaction time. The T-Test showed that in females there was a significant difference in reaction time before and after drinking Red Bull. Finally the mean reductions in reaction time for both males and females were compared using the T-test, which revealed that there was a significant difference in male and female reductions in reaction time. This leads to the conclusion that between the ages of 16- 17, Red Bull only significantly reduces reaction time in females and not in males. Introduction Research Question How significant is the reduction in reaction time due to intake of Red Bull, in males as compared to females between the ages of 16-17. It gives you wings this is the slogan for Red Bull, a popular energy drink. The slogan suggests that Red Bull improves ones overall performance. Reaction time is one of the physical attributes affected by Red Bull. I wanted to investigate Red Bulls effect on reaction time and evaluate whether Red Bull really does give you wings. Reaction time is the time taken to respond to any given stimulus. The better the reaction time, the less it is. Fast reactions are useful in many situations, for instance avoiding another car whilst driving, catching a falling glass and even in sport. Previous research into reaction time has found that Males and females generally have different reaction times with females unfortunately having slower average times. (Der and Deary, 2006). Energy Drinks are beverages that have a boosting or stimulating effect. They are often advertised as performance enhancing, with improvements in alertness and reaction time. Red Bull is probably the most prominent energy drink. The active ingredients in Red Bull include: Glucose, Taurine, Glucuronolacton, Inosital, Niacin, D-Pantothenol (Vitamin B5), Pyridoxine HCL (Vitamin B6), Vitamin B12 and Caffeine. (Further details in appendix ii.). These chemicals affect the bodys metabolic functions so that overall performance is enhanced. My approach was experimental in which the Ruler Drop Test (Coach, 1997) was used. Hypothesis I hypothesise that Red Bull will cause a decrease in reaction time in all subjects. This is due to the ingredients contained in the drink. Taurine and caffeine are the two ingredients that affect the speed of reaction most. Taurine improves nerve transmission; this means that movements made will be faster. Caffeine boosts adrenaline levels which makes one more alert and therefore more likely to respond faster. Thus, I expect reaction time to decrease in all subjects. I also hypothesise that the improvements in reaction time will be more significant in females as they generally have a smaller body mass meaning that the active ingredients in Red Bull will have more of an effect. Experiment Test Subject Selection It was important to make sure that the results from the experiment were as reliable as possible. To do this I had to choose test subjects (participants in the experiment) who were similar in age, athleticism and how frequently they take energy drinks. I decided to use subjects within the age range of 16-17 as this is the age range with the most people in my school and therefore there was a larger test subject range. I had to keep the ages similar because age was found to have an effect on reaction time. (Gorus et al., 2008) Generally reaction time decreases with age until a certain point where it begins to increase again. I wanted subjects who were similar in athleticism because people who are more athletic are more likely to have quicker reaction times than non-athletic people. (Levitt and Gutin., 1971) I also needed subjects who didnt take Red Bull as frequently. It was assumed that people who take energy drinks frequently may develop resistance to its effects. A questionnaire was used to identify the subjects that fit in with these criteria. It was given to 40 people out of whom 10 males and 10 females were selected using random sampling. Preparation of Subjects The test subjects had to be prepared before the experiment to ascertain that it was in fact the Red Bull that was affecting the subjects reaction time and not any other food. The Red Bull was administered an hour after break time. It was assumed that by this time all food (if any) would have been digested. This was important because the Red Bull has to be the only substance ingested prior to the experiment to make sure that the results obtained are from the effects of Red Bull and not any other food substance. Testing took place 10 minutes after consumption to give the active ingredients in the Red Bull enough time to be assimilated. Procedure The Ruler Drop Test was carried out using the following method. A ruler was held so that it was between the index finger and thumb of the subjects stronger hand. The top of the subjects thumb was kept in line with the zero centimetre line on the ruler. The subject then tried to catch the ruler after it was let go. The distance from the bottom of the ruler to the top of the subjects thumb was recorded. To improve reliability of the results the experiment was repeated again. It would be nearly impossible to manually record the time taken for someone to catch a dropped ruler because this happens very quickly. So to calculate the time taken (and thus reaction time) the following formula was used. t = à ¢Ã‹â€ Ã… ¡(2d /a) This was derived from: d = vt +  ½at ² [11] d is Distance measured in (cm) v is Initial velocity which is zero a is Acceleration due to gravity this a constant value of 981cm/s ² t is Time measured in seconds (s) Data Collection The tables below show the results from the ruler drop test conducted on 9.7.2010. It shows the distances that the ruler travelled before it was caught by the subjects. The results before and after drinking Red Bull were recorded. The experiment was repeated twice to improve the reliability of the results. Trial 1 Trial 2 Males Females Males Females Subject number Distance Before Drinking Red Bull +/-0.05 (cm) Distance After Drinking Red Bull +/-0.05 (cm) Distance Before Drinking Red Bull +/-0.05 (cm) Distance After Drinking Red Bull +/-0.05 (cm) Distance Before Drinking Red Bull +/-0.05 (cm) Distance After Drinking Red Bull +/-0.05 (cm) Distance Before Drinking Red Bull +/-0.05 (cm) 1 16 13 16 9 9 6 12 2 15 14 15 17 12 8 9 3 5 9 30 17 7 5 17 4 8 9 22 11 8 5 13 5 15 11 18 12 6 7 15 6 12 7 19 19 10 7 11 7 6 7 15 11 9 8 16 8 14 8 17 10 11 6 10 9 7 6 14 12 5 8 12 10 14 17 14 10 13 15 15 Data Processing The raw data was processed to give the tables below. The values in red show anomalies, that is data that is erroneous and/or unexpected, in this case distances increasing after taking Red Bull and Reaction Time increasing after taking Red Bull. These values could be generated by an error in the data collection or an error in the experiment. They are therefore ignored when considering the significance. The tables below show the calculated reaction time before and after drinking Red Bull. Reaction times were calculated using the distances obtained from the experiments which were then substituted into the formula. t = à ¢Ã‹â€ Ã… ¡(2d /a). The tables also show the difference in reaction time which is the reaction time after drinking Red Bull, subtracted by the reaction time before drinking Red Bull. This was done so that that the improvement in reaction time can be seen. Table (1.a) shows the data from the 1st repeat and table (1.b) shows data from the 2nd repeat and Table (2) shows the mean of both repeats. In this table, most of the errors disappear as the mean uses the data from both sets of repeats to show an average or trend. Examples: Calculating Reaction Time A subject catches the ruler at 16.0 cm without drinking Red Bull. The subject then catches the ruler at 13.0 cm after drinking Red Bull. The time taken for the subject to catch the ruler is worked out like this. Distance before taking Red Bull= 16.0 cm Formula: t = à ¢Ã‹â€ Ã… ¡(2d /a) So 216.0= 32 32/981= 0.03262 à ¢Ã‹â€ Ã… ¡ 0.03262= 0.18061 Therefore it took the subject 0.18061 seconds to catch the ruler before drinking Red Bull. Distance after taking Red Bull=13.0 cm 213.0= 26 26/981= 0.02650 à ¢Ã‹â€ Ã… ¡0.02650= 0.16280 Therefore it took the subject 0.16280 seconds to catch the ruler after drinking Red Bull. Calculating Difference The subjects Reaction time before drinking Red Bull is 0.18061 seconds and the subjects reaction time after drinking Red Bull is 0.16280 seconds. To find the difference the subjects reaction time after drinking Red Bull is subtracted by the Reaction time before drinking Red Bull to give: -0.01781. In this example, the calculated difference in reaction time is negative. This shows that after drinking Red Bull, the subjects reaction time improved by -0.01781 seconds. Calculating the Mean In the second repeat of the experiment the subject catches the ruler at 9 cm before drinking Red Bull and then catches the ruler at 6cm after drinking Red Bull. The subject therefore gets these reaction times: Before drinking Red Bull: 0.13546 sseconds. After drinking Red Bull: 0.11060 seconds. The mean for reaction time before and after drinking Red Bull can be calculated, using the values from the 1st and 2nd repeats of the experiment. Mean reaction time before drinking Red Bull: 0.18061 + 0.13546= 0.31607 0.31607 / 2= 0.158035 seconds Mean reaction time after drinking Red Bull: 0.13546 + 0.11060= 0.24606 0.24606 / 2= 0.12303 seconds The mean shows a more reliable value from both repeats.

This is done below: Graph (1.a): The graph (1.a) shows the comparison of the mean male reaction time before and after drinking Red Bull. The graph shows that generally the blue bar (Male Reaction Time before Drinking Red Bull) is higher than the red bar (Male Reaction Time After Drinking Red Bull) This suggests that Red Bull generally had the effect of reducing reaction time in males. Red Bull contains Taurine (see appendix ii) Taurine speeds up neural transmission, so nerve impulses are passed along through the nervous system much faster. This means that the time taken for the subjects hand to react to the stimulus (in this case the dropped ruler) is less. Another ingredient that probably affects reaction time most is caffeine. Caffeine blocks adenosine and boosts adrenaline levels. Adrenaline causes the heart rate to increase, the respiratory rate in the lungs to increase and muscle contraction all around the body. These are just some of the effects known as the fight or flight response. The overall effect is that you respond better to stimuli as the body is more alert. T Test The T-Test shows how significant the statistical difference between two values is. The T-Test determines the P-Value. In Biology the difference between the two values is considered statistically significant if the P value is below 0.05 If it is The Null hypothesis is therefore rejected and the alternative hypothesis is accepted. Null Hypothesis: There is no significant difference in reaction time before and after drinking Red Bull in Males. Alternative Hypothesis: There is a significant difference in reaction time before and after drinking Red Bull in males. For this T-Test I compared the mean values of reaction time before and after drinking Red Bull for males. I got a P-Value of 0.06626028. This is greater than 0.05 therefore the Null hypothesis has to be accepted. The T-Test suggests that with males, the difference in reaction time after drinking Red Bull is not significant because the P value (0.06626028) is greater than the standard critical value (0.05). Graph (1.b) The graph (1.b) shows the comparison of the mean female reaction time before and after drinking Red Bull. Again, the graph shows that generally the blue bar (Female Reaction Time after Drinking Red Bull) is higher than the red bar (Female Reaction Time Before Drinking Red Bull) This suggests that Red Bull generally had the effect of decreasing reaction time in females. This decrease is again due to the ingredients contained in Red Bull. Both taurine and caffeine affect the subjects system so that the speed of movement and response in increased. T-Test Another T-Test is carried out to find out how significant the difference in reaction time before and after drinking Red Bull in females is. Null Hypothesis: There is no significant difference in reaction time before and after drinking Red Bull in Males. Alternative Hypothesis: There is a significant difference in reaction time before and after drinking Red Bull in males. For this T-Test I compared the mean values of reaction time before and after drinking Red Bull for females. I got a P-Value of 0.00068587. This is less than 0.05 therefore the null hypothesis is rejected and the alternative hypothesis is accepted. The T-Test suggests that the differences in the female reaction time before and after drinking Red Bull are very significant as the P value (0.00068587) is far below the standard critical value of 0.05. The final step in analyzing the data is to compare male and female change in reaction times. Graph (2) Graph (2) shows the Comparison of Male and Female reduction in reaction time. The pink plot points show the mean female difference in reaction time; whilst the blue plot points show the mean male difference in reaction time. The graph shows that generally mean male reduction in reaction times were much lower than the mean female reduction in reaction time. This suggests that females are affected more by Red Bull. Another observation that can be made from the graph also shows that the female data is more varied than the male data. However the data that was collected was too small to make any definite conclusions. T-Test A T-Test was carried out to find out how significant the difference in mean male and female difference in reaction time. Null Hypothesis: There is no significant difference between mean male and female difference in reaction time. Alternative Hypothesis: There is a significant difference between mean male and female difference in reaction time. In this T-Test I compared the mean values of difference in reaction time for both males and females. I got a P-Value of 0.001571698. This is less than 0.05 therefore the null hypothesis is rejected and the alternative hypothesis is accepted. The T-Test suggests that there is a big significance in the difference between mean male and mean female difference in reaction times because the P value is much lower than the critical value of 0.05. Conclusion In general, reaction times decreased after drinking Red Bull in both males and females. Males generally had faster times females. However the T-Test shows that in males this difference is not significant whilst in females, it is quite significant. Further calculations showed that there was a significant difference between the reduction of reaction time in males and females. Females generally had greater reductions in reaction time. The data does not support the first hypothesis, which states that reaction time would decrease in all subjects after the consumption of Red Bull, as there were some instances where the reaction times worsened. These anomalies may have been due to error in the method however, and had no overall significance to the experiment as they were ignored. The data supports the final hypothesis, which states that Red Bull would improve reaction time more significantly in females. The results from the investigation show that females had a more significant reduction in reaction time after drinking Red Bull as compared to males. The reason for females being affected more by Red Bull is, Pound for pound females have less water in their bodies than men, so their body parts are more exposed to the active ingredients in Red Bull. This leads to the conclusion that between the ages of 16-17, Red Bull only significantly reduces reaction time in females and not in males. Evaluation There were some aspects of the experimental method that may have reduced the reliability of the data. When the ruler drop test was performed for the second time the subjects instead of improving reaction time as a result of drinking Red Bull may have naturally improved their reaction time through practice. Also the subjects knew that they were drinking Red Bull and that Red Bull is said to improve physical performance including reaction time. This again may have caused them to improve their times naturally through the psychological stimulation. There is no actual proof however that improvement in reaction time was due to practice. It is only a speculation. However if the subjects reaction times were improving as a result of practice then this would affect the data as Red Bull would not be the only factor improving reaction time. The best way to reduce the effect of this factor would be to carry out the experiment only once. This would reduce the reliability of the data as a mean of both experiments not would be possible to calculate but at the same time it would improve the reliability of the data as subjects would not be getting better with practice and it would be only the Red Bull affecting the subjects reaction time. I also could have set up another Ruler Drop Test experiment using a different set of subjects but replacing the Red Bull energy drink with a non energetic drink. The subjects however, would be told that they are having another brand of energy drink. This would test the thought of having an energy drink makes the subject expect to perform better and therefore actually improving their reaction time naturally. A second experiment using the same subjects could then be carried out using but using Red Bull. The results of the second experiment could then be compared with the results from the first experiment to further asses the significance improvement in reaction time due to Red Bull. Error Analysis 30 cm Ruler (cm) Absolute uncertainty +/- 0.05 Percentage Uncertainty % 0.25 Overall Uncertainty % 0.25 Appendix (i) Questionnaire How old are you: ____ 2. How Much Sport do you do?

Appendix (ii) Active ingredients in Red Bull: Glucose Glucose is a sugar. The body uses glucose in respiration to make energy. C6H12O6 + 6O2 = 6H2O + 6CO2 + 36ATP Glucose + Oxygen = Water + Carbon Dioxide + Energy. Redbull contains 5.25 g of glucose. Taurine Taurine is an amino acid that is usually made in the body. Each can of Red Bull contains 1000mg of Taurine. Taurine helps move minerals like potassium, sodium, calcium and magnesium through the cells. This helps to generate nerve impulses therefore making neural transmission faster. Glucuronolacton Glucuronolacton is a chemical similar to taurine. It affects memory and concentration in the brain. It is known to have effects similar to anti-depressants and stimulants. Inosital Inosital is a chemical that has a mood boosting effect and it maximises the brains uses of a serotonin a chemical that is found in most anti-depressants. Niacin Niacin is a B vitamin that helps in energy formation. It metabolizes energy from fat and carbohydrates. Niacin can help the body use energy by releasing it from food. D-Pantothenol D-Pantothenol is also known as vitamin B5, or Pantothenic acid. It is known to improve mood and boost energy. D-Pantothenol help turn fat into energy and increases metabolism. Pyridoxine HCL Also known as Vitamin B6, Pyridoxine HCL helps red blood cells to form and provides better oxygen utilization. It also help to break down sugar that you have stored in your body to use for energy. Vitamin B12 B12 helps in the formation of red blood cells, for better oxygen utilization. It also help with energy production by breaking down fat and protein. Caffeine Red Bull contains 80.0 milligrams of caffeine which is almost double the amount of all other soft drinks. The caffeine in Red Bull gives you energy by blocking a chemical in your brain called adenosine. Adenosine promotes sleepiness and without it you would not be able to fall asleep. When adenosine is blocked you body releases a boost of adrenaline which wakes you up.

Industry essay: What are Web Services? -- Computer Science

Industry essay: What are Web Services? Web services have been hyped over the past year to be the most innovative improvement that has come to the Internet. It has been adopted by many companies, and has reached the forefront of applications development. So what is all the hype about? Web services can be described as an application that can be deployed or called over the Internet that allows applications to communicate with each other- regardless of the language in which they are written or which systems platform and operating system is being used. Each service is a discrete unit of code, and performs a small set of given tasks. Typically, web services make use of standard web protocols to perform its tasks- it usually follows an order: 1) find the web service requested, 2) determine how the web service is called once it is found, and 3) call the program or service requested. For the search portion, UDDI (Universal Discovery, Description, and Integration) is mainly used. It is a service that essentially is a directory of web services, and UDDI helps the user find the web service or program for which he is looking. WSDL (Web Service Definition Language) is most often used to describe how the web service or program should be called, and XML to communicate this. Finally, Simple Object Access Protocol (SOAP) encodes the XML data sent and received, and shares the data in messages over http. The potential power of web services can be displayed in a number of different ways. Web services are being used to integrate all sorts of data- from local programs interfacing with each other across a local area network, to large enterprise-level applications communicating across the Internet. A few examples of how web services can be utilized are listed below: * A utility pole is damaged in a remote area of Massachusetts, and a utility company has to come in and replace it. However, in order to do this, the cable, telephone, and electric utility companies have to act in a certain order in order for the damaged pole to be removed. Web services can be used to determine the status of the actions taken by the individual companies, since the order of the actions is based on which utility owns the pole. * A company wants to measure how much a particular product it has sold, which customers bought how much of the product, when the nex... ...partners." In other words, web services allow the bounds on software integration to be greatly expanded. It is now a great selling point for companies, particularly those that develop software. And at first, those companies that develop web services will benefit, but the success will eventually give way to those businesses that leverage web services in the most useful manner.

Effects of Fatherlessness essays

Effects of Fatherlessness essays It is a common belief that the decline of fatherhood is one of the most basic, unexpected, and extraordinary social trends of our time (Tischler, 2001, p.19). However, the opposing view of this standpoint is that there is no decline in fatherhood. There are very few people saying that they doubt the fundamental importance of mothers, yet there are those that believe that the importance of a father figure is diminishing (Tischler, 2001). There are even those who see the father position in a family to be easily replaceable with another figure such as a stepfather, aunt, uncle, grandparent, or any other person (Tischler, 2001). My view on the topic of whether or not a father is needed in a family, and yes I mean the birth father, not a replacement, is based upon my own upbringing. Since I am a male and am in the position of being a potential father, it only makes sense that I see the position of the father as an instrumental one pertaining to the upbringing of a child. I am constantly surrounded by those who are in a family where either their parents are divorced and remarried, or those who live in single-parent household. I am biased on the issue of why a father figure is necessary due to the fact that I was raised, and am still being raised in a household where my parents remain married. I couldnt possibly imagine being raised in a family that is broken because Ive never experienced that situation. Therefore I find it a necessary that there be a father present in the lives of their children. After deciding on the topic of fatherhood and why it is important, I gathered the necessary information pertaining to my topic out of the book: Marriage and the Family Issues by H.L. Tischler. After reading through the article written by David Popenoe entitled A World Without Fathers I was informed on the stance of why it is imperative to have a father in the house while a child is growing up.

The Great Gatsby Dreams Essays - The Great Gatsby, Daisy Buchanan

The Great Gatsby Dreams Essays - The Great Gatsby, Daisy Buchanan The Great Gatsby Dreams The Great Gatsby Dreams The Great Gatsby by F. Scott Fitzgerald, is a novel about the American Dream. In the Great Gatsby, the dream is that one can acquire happiness through wealth and power. To get his happiness Jay attempts to reacquire the love of his lost sweet heart, Daisy. The main problem with Jays dream is that Daisy is all ready married. Gatsby's personal dream symbolizes the larger American Dream The pursuit of happiness. Jay Gatsby longs for the past. Surprisingly he devotes his adult life trying to recapture it and dies in its pursuit. In the past, Jay had a love affair with a young rich girl, Daisy. Daisy and Jay had fallen in love with each other in spite of knowing that they could not marry because of the difference in their social status. For the first time in Jays life he was truly happy. During their courtship, Jay was sent off to war. Upon returning from the war, Jay found out that Daisy had married a wealthy man by the name of Tom Buchannon. Jay then spends his life acquiring wealth to reach her economic standards, in hope that he can marry her and rekindle the happiness that he once had. His love for Daisy was impossible in society because he was at present a penniless young man without a pasthe had no comfortable family standing behind him (156). Gatsby encounters his dream of love at this point of his life. He knew that at that time a relationship of love was impossible with Daisy due to his low social standing. Gatsby became determined to breach that gap between them in order to have a loving relationship with Daisy. He did reach the physical circumstances necessary to love her, but he had focused too much on money and power the previous five years of his life. He wanted his love with Daisy to flourish. Unfortunately, he had lost the ability to love. He no longer possessed moral integrity or the ability to handle a relationship. Society is often broken up into different social groups by their economic status. Those of lower classes believe that their problems will go away if they can gain enough wealth to reach the upper class. Many people believe that the American Dream is this joining of the upper class, and once reaching that point, not having to be concerned about money at all. The logic behind this is that being poor keeps people from being happy, and once you become rich, you do not have to struggle with the problems of life, and can therefore be happy. The Great Gatsby takes this belief, and shows its flaws through the lives of Jay, Tom and Daisy. In fact, all of the characters in the story are affected in some way by the lives of these three characters. Gatsby makes becoming an upper class citizen his priority. The life of the upper class in turn, makes the acquisition of wealth their priority. Wealth becomes Jays vehicle in his quest for his primary goal, Daisy. In Gatsby's rise to power morality is sacrificed in order to attain wealth. While the story does not go into great detail as to how Gatsbys wealth was accumulated, it can easily be seen that his business ventures were shady at best. Gatsby's dream was doomed to failure because of his lack of principles. This shows a major flaw of the American Dream philosophy, just like the get rich quick schemes of today, Jay is trying to buy Daisys love, not earn it. Nick attempts to tell Jay that his dream is pointless by saying that the past cannot be relived. Jay quickly told Nick, Yes you can, old sport. This shows the confidence that Jay has in fulfilling his American Dream, and his commitment to it. Tom Buchanan, Daisys husband, was a man from an enormously wealthy family. Nick, described Tom's physical attributes as having a hard mouth and a supercilious mannerarrogant eyes had established dominance over his facealways leaning aggressively forwarda cruel bodyhis speaking voiceadded to the impression of fractiousness he conveyed (11). The wealth Tom has inherited causes him to become arrogant and condescending to others. Tom believed that

Economic and Political Importance of Medieval Fairs in Europe Essay

Economic and Political Importance of Medieval Fairs in Europe - Essay Example This essay outlines economic and political significance of holding of fairs during medieval times in Europe. The main trade fairs were held in the European region mainly France, Germany and England. The most renowned fair was one held in Champagne region in France. Medieval fairs and markets first started as social gatherings, however, with time the fairs became central to the medieval economy. Major economic centers which were mainly big towns selected a particular day where people would congregate with their merchandise. Initially, the fairs would only involve local people but as travel became easier and safer, traders began to make long travels to participate in these fairs. This also opened up trade routes allowing a more widespread participation which also meant that the fairs had a wider variety of wares. Items brought forward were dependent on the main products available in different areas of the traders. The main commodities involved were wool and lead from England, iron from Spain, and silk and spices from the Middle and Far East. The fairs extended because the different participants had a different commodity to offer. Basically, this is what sustains every trade as people continue to demand for that which is not at their disposal. These trade fairs were sustained for both political and economic reasons. The main merchants and the political class had identified that trade fairs formed a basic source of revenue, this came through taxes and other form of duties levied to traders who came to sell their wares.

History through A Geographers Lenses Essay Example | Topics and Well Written Essays - 1250 words

History through A Geographers Lenses - Essay Example 244). We can take this to mean that modern society began sometime in the late 1800s and early 1900s and last to this day. What made the 19th century a turning point Van Doren further cites (p. 245) the progress resulting from the disruptive technological discoveries that took place, whether "it be new energy sources like oil and electricity, new means of living comforts like electric lights and cheap cast iron stoves, and new devices for communication on both a local and global scale such as the telegraph and the telephone." Several lenses are available to read the history of modern societies from that point on, and what we use will depend on one's point of interest. A student of geography like myself would use as my lenses the three dimensions most appropriate for the task: speed, space, and time. From a geographer's viewpoint, one can see the development of modern society and its history in relation to how human activities affected and was affected by speed, space, and time. ... human interaction by which ideas and information in the form of physical signals like words and actions are exchanged, was limited by space or distance and time. The time it would take for ideas to travel from one point of the globe to another depended on the (rather slow) speed of the carrier of the message, a combination of horses, ships, pigeons, or human runners before Morse discovered the telegraph in the mid-1800s. In some regions like the jungles of the Amazon or the wide plains of America and Europe, messages were carried across limited distances by drums and flags. The effectiveness and efficiency of these modes of communication were limited by distance, the speed of sound, and the sharpness of hearing and sight. Prior to the discovery of the telegraph, sharing and receiving information and then taking action or giving feedback took a long time, which accounted for the slow pace of development of human history that is the result of the interaction of human activities. The telegraph changed all that by accelerating the exchange of information and increasing the pace of human interaction and, in its turn, the amount of human activity. What resulted was a snowballing of social consequences that gathered in size and the power to effect change. The telegraph reduced space because it made human interaction across great distances possible, allowing people across the continents hundreds or thousands of miles apart to communicate and to initiate appropriate action. It also reduced time in a radical way, because by speeding up the exchange of information, it was possible to undertake human action sooner instead of wasting time while waiting for information and feedback to come. However, the telegraph had one major drawback: information in the form of messages had
