Petroleum and Middle Indus Basin Essay Example

Petroleum and Middle Indus Basin Essay Kohat-Potwar Oil and Gas Exploration and Production The first oil well drilled in present-day Pakistan was at Kundal on the Potwar Plateau in 1866. The first commercial oil discovery was made in the Greater Indus Basin in 1914 when the Attock Oil Company completed a 214 ft well on a thrust-faulted anticline near Khaur on the Potwar Plateau (Khan and others, 1986). Early success in the Kohat-Potwar geologic province served to focus much of the early exploration activity in that area. The Sui field in the Sulaiman-Kirthar Foreland geologic province was the first discovery outside of the Kohat-Potwar geologic province and is the largest gas discovery in Pakistan, with more than 5 trillion cubic feet (TCF) of gas reserves. Discovered in 1952, the Sui field is a dome-shaped reef structure with an anticlinal surface expression. The largest reserves were found in the 625 m thick Eocene Sui Formation Sui Main Limestone Member. The Sui Upper Limestone Member and upper Eocene Habib Rahi Limestone were also productive. In 1999, Upper Cretaceous Pab Sandstone Formation gas production began at Sui field. Although exploratory wells had been previously drilled in the Middle and Lower Indus Basins, the discovery of the Sui field accelerated exploration efforts in the 1950s. More discoveries followed in that area with the Zin gas field in 1954, the Uch gas field in 1955, and the Mari gas field in 1957. Exploration activity increased again in the 1980s, when identification of a tilted fault block in the Lower Indus Basin led to the discovery of a series of oil fields. Although there have been significant oil discoveries in the Lower Indus Basin, it remains a gas-prone province.

The Cambrian oil discoveries in Rajasthan, however, are beyond the extent of Sembar deposition and are either sourced by updip hydrocarbon migration from the Sembar or more likely by proximal older Mesozoic and early Paleozoic rocks. Sembar-Goru/Ghazij Composite Total Petroleum System The Sembar-Goru/Ghazij Composite Total Petroleum System (TPS) as defined for this assessment, is a north-south elongated area extending from the Potwar-Kohat geologic province in the north to the 2,000 m bathymetric contour in the Arabian Sea . The west boundary coincides with the axial belt and western edge of the Indian plate and the eastern boundary extends into India on the Indian Shield . Geochemical analyses of potential source rocks and produced oil and gas have demonstrated that the Lower Cretaceous Sembar Formation is the most likely source of oil and gas for most of the producing fields in the Indus Basin. Source Rocks While the Sembar has been identified as the primary source rock for much of the Greater Indus Basin, there are other known and potential source rocks. Rock units containing known or potential source rocks include the Salt Range Formation Eocambrian shales, Permian Dandot and Tredian Formations, Triassic Wulgai Formation, Jurassic Datta Formation, Paleocene Patala Formation, Eocene Ghazij Formation, and lower Miocene shales. Of all the possible source rocks in the Indus Basin, however, the Sembar is the most likely source for the largest portion of the produced oil and gas in the Indus foreland. In the Kohat-Potwar geologic province the Paleocene Patala Shale is the primary source rock for most, if not all of the province. In the offshore areas of the Indus geologic province, Miocene rocks are postulated to be good hydrocarbon sources, with the Sembar contributing in the shelf area. The Lower Cretaceous Sembar Formation consists mainly of shale with subordinate amounts of siltstone and sandstone. The Sembar was deposited over most of the Greater Indus Basin in marine environments and ranges in thickness from 0 to more than 260 m (Iqbal and Shah, 1980). Rock-eval pyrolysis analyses of 10 samples from the Jandran-1 well in the Sulaiman Range of the foldbelt, indicate an   most likely prove to be gas prone. verage total organic carbon content (TOC) of 1. 10 percent. The TOC values from the Sembar in two Badin area wells in the foreland portion of the Lower Indus Basin have TOC’s ranging from 0. 5 to 3. 5 percent and averaging about 1. 4 percent. A cross-plot of pyrolysis data on a modified van-Kreveln diagram study indicates that the organic matter in the Sembar is mainly type-III kerogen, capabl e of generating gas; however, additional proprietary data indicate the presence of type-II kerogen as well as type-III kerogen. With respect to the oil window (0. 6 1. 3 percent vitrinite reflectance), the Sembar ranges from thermally immature to over mature . The Sembar is more thermally mature in the western, more deeply buried part of the shelf and becomes shallower and less mature toward the eastern edge of the Indus Basin   Conclusive geochemical data supporting a Sembar source for most of the produced oil and gas in the Indus Basin are lacking; however, limited available geochemical and thermal data favor a Sembar source. To date, the only oil-productive regions in the Greater Indus Basin are the Potwar Plateau in the north and the Badin area in the Lower Indus Basin. Cross-plots of the carbon isotope ratios and the isoprenoid ratios of produced oils in these two regions are distinctly different , indicating two different source rocks. Gas content varies throughout the basin with CO2 ranging from lt; 1 percent to gt;70 percent, nitrogen lt; 1 percent to gt; 80 percent, and H2S lt; 0. percent to gt; 13 percent (IHS Energy Group, 2001). Reservoirs Productive reservoirs in the Sembar-Goru/Ghazij Composite TPS include the Cambrian Jodhpur Formation; Jurassic Chiltan, Samana Suk, and Shinawari Formations; Cretaceous Sembar, Goru, Lumshiwal, Moghal Kot, Parh, and Pab Formations; Paleocene Dungan Formation and Ranikot Group; and the Eocene Sui, Kirthar, Sakesar, Bandah, Khuiala, Nammal, and Ghazij Formations . The principal reservoirs are deltaic and shallow-marine sandstones in the lower part of the Goru in the Lower Indus Basin and the Lumshiwal Formation in the Middle Indus Basin and limestones in the Eocene Ghazij and equivalent stratigraphic units . Potential reservoirs are as thick as 400 m. Sandstone porosities are as high as 30 percent, but more commonly range from about 12 to 16 percent; and limestone porosities range from 9 to 16 percent. The permeability of these reservoirs ranges from 1 to gt; 2,000 milidarcies (md). Reservoir quality generally diminishes in a westward direction but reservoir thickness increases. Because of the progressive eastward erosion and truncation of Cretaceous rocks, the Cretaceous reservoirs all have erosional updip limits, whereas Tertiary reservoirs extend farther east overlying progressively older rocks. Traps All production in the Indus Basin is from structural traps. No stratigraphic accumulations have been identified, although the giant Sui gas field is a dome-shaped reef structure (possibly an algal mound) expressed on the surface as an anticline. The variety of structural traps includes anticlines, thrust-faulted anticlines, and tilted fault blocks. The anticlines and thrusted anticlines occur in the foreland portions of the Greater Indus Basin as a consequence of compression related to collision of the Indian and Eurasian plates. The tilted fault traps in the Lower Indus Basin are a product of extension related to rifting and the formation of horst and graben structures. The temporal relationships among trap formation and hydrocarbon generation, expulsion, migration, and entrapment are variable throughout the Greater Indus Basin. In the foreland portion, formation of structural traps pre-date hydrocarbon generation, especially in the Lower Indus Basin. In the Middle and Upper Indus Basins, traps may also have formed prior to hydrocarbon generation, although the temporal relationships between trap formation and hydrocarbon generation are not as distinct as in the Lower Indus Basin. The structural deformation in the foldbelt region is generally contemporaneous with hydrocarbon generation, suggesting that some of the hydrocarbons generated from the Sembar probably leaked to the surface prior to trap formation. Burial history reconstructions based on data from the Sakhi-Sarwar no. 1 well , located in the foreland part of the Middle Indus Basin, and the Shahdapur no. 1 well, located in the foreland part of Lower Indus Basin, indicate that hydrocarbon generation began 40 and 65 Ma, respectively . The main differences in the hydrocarbon generation times between these wells are due to large differences in the thermal gradients; the present-day thermal gradient in the Sakhi-Sarwar well is 2. 6 °C/km as opposed to 3. 3 °C/km in the Shahdapur well. We interpret the critical moments for these wells at about 15 and 50 Ma, respectively. Based on these reconstructions, trap formation may have postdated the start of hydrocarbon generation in the foreland portion of the Indus Basin. Seals The known seals in the system are composed of shales that are interbedded with and overlying the reservoirs. In producing fields, thin shale beds of variable thickness are effective seals. Additional seals that may be effective include impermeable seals above truncation traps, faults, and updip facies changes. Overburden Rock The rocks overlying the Sembar are composed of sandstone, siltstone, shale, limestone, and conglomerate. The maximum thickness of these overlying rocks is estimated to be as much as 8,500 m in the Sulaiman foredeep area . In the foredeep areas immediately adjacent to the front of the foldbelt parts of the Indus Basin, the overburden thickness ranges from 2,500 m to 6,000 m. East of the foredeep, overburden rocks thin as Cretaceous and Paleocene rocks are progressively truncated.

Solar Stoms Angel has returned to Adams’s Rib to find her roots. She is a 17-year-old girl in search of her family and most of all, who was her mother Hannah Wing (p 21). This is also a spiritual quest for Angel, yet that is only an observation that I became aware of after reading this novel Solar Storms. This novel begins with Angel’s arrival at Adam’s Rib on Tinselman’s Ferry (p21). We are given a small history of the settlers – the British, Norwegians and Swedes. Here the groundwork is being laid out by Linda Hogan on how these lands were shaped, and the importance of the water. We are told of a woman in a canoe appearing out of the fog (p22). Also we are given great detail of the terrain. Angel is on a quest to meet her family and find out who her mother Hannah Wing was. Angel comes to Adam’s Rib at the invitation of her great grandmother, Agnes Irons (p 23). At this point and throughout the novel, Linda Hogan takes great care to show the reader great details of the surroundings so that the reader feels present in the story. Or one with the characters, you can almost smell the fish and tress, see the sky and experience the desolation and barrenness of the land as well as the beauty. We see through this description the simple life people are leading. These people who live off the land. Angel arrives scared, alone with her worldly possessions – two garbage bags (p23). Angel is welcomed by her great grandmother Agnes, who is so happy to see Angel, and caught with great emotion and cries tears of joy at Angel’s arrival (p25).

Ethical Dilemma Essay Assignment Example | Topics and Well Written Essays - 1500 words

Ethical Dilemma Essay - Assignment Example Therefore, since there is no choice in the matter, there is no breach of confidentiality or ethical violation when a student discusses a case with a supervisor. The second condition for an ethical dilemma is that there should be an alternative course of action to choose from. The third condition is that no matter the choice of action, some ethical principles should be compromised i.e. there is no proper solution (Cheryl R. Lehman, 2010). In order to determine what constitutes an ethical dilemma, it is important to make necessary distinction between ethics, morals, values, laws and policies. Ethics comprises of propositional statements used by members of certain profession or a group to determine what is right and wrong in a given situation. Ethics rely on rational and logical criteria during the decision making process. On the other hand, values describe the ideas that we value the most. To value something means to hold it dearly and feel a sense of worthiness in it. Morals describe a certain code of behavior that an individual ascribes and used to negotiate and strengthen our relationship. Since employees take most of their time during the weekday in the office, they are tempted to carry out their own businesses in the company’s time. This may comprise of such instances like setting up an appointment with a doctor using the company’s phone lines, use of the company’s computers to make vacation reservations or even making freelance calls during office working hours. At the first instance, this ethical dilemma is quite clear: it is time and other abuse of employer’s time and resources to do personal business especially during the official working hours. But here are some shades of gray. Suppose your spouse calls to inform you that your children are sick? Is it right to look for a doctor’s appointment? It is very essential for an employee to check with his supervisor or manager so as to clarify what amounts to an actionable

Jesus as a Figure in History Case Study Example | Topics and Well Written Essays - 1500 words

Jesus as a Figure in History - Case Study Example These young girls start comparing themselves with the women shown on the television who are nothing but a piece of crap as they are full of make up and designer label clothes on their skinny figures. One needs to remember that many of these models shown on television and more so on the fashion channels have eating disorders and some pictures as well as images of women shown on television and in movies have been falsely created from a number of different bodies, thanks to computer graphics and software that now make it possible. The extreme images of torture, sex and liberalism shown on television project a very significant impression on the minds of the people and more so the ones who do not have related exposure to such cultural tangents. (Author Unknown, 2004) These people start taking such images and movies as a part of their lives even though such television programming is far from the truth. Thus people's behavior comes across as being directly in line with what is being shown on television and their perspectives start to alter as a result of the same. Last cause of television and movies' excessive viewing is in the form of a number of diseases and mostly related with the eyes of the people. This means that the people watching can fall prey to a number of ailments which can have negative repercussions in the long term. These maladies could result in the Attention Deficit Disorder or ADHD as well as other diseases from time to time. The lives of the people are thus affected immensely by viewing television for stretch and it is best advisable to limit viewing under such measures. Television has diversified its transmissions into different fields like information, education, entertainment, live news, documentaries, reports, sports coverage, presentations, game shows, etc. What this in essence means is that the television is a significant tool at portraying the different aspects which usually happen within a society's life time. People can easily expect television to cover each and every detail related with them and thus show them what is happening throughout the world, 24 hours a day, 7 days a week and 365 days a year.

Hotel Rwanda | Film Analysis

Hotel Rwanda | Film Analysis Directed by Terry George. It was adapted from a screenplay written by George and Keir Pearson. Based on real life events in Rwanda during the spring of 1994, the film stars Don Cheadle as hotelier Paul Rusesabagina, who attempts to rescue his fellow citizens from the ravages of the Rwandan Genocide. Actors Sophie Okonedo, Joaquin Phoenix, Nick Nolte and Jean Reno also appear in principal roles. The film, which has been called an African Schindlers List, documents Rusesabaginas acts to save the lives of his family and more than a thousand other refugees, by granting them shelter in the besieged Hà ´tel des Mille Collines. Hotel Rwanda explores genocide, political corruption, and the repercussions of violence Hotel Rwanda tackles one of the most horrifically ugly events in recent history, when the Hutu extremists of Rwanda initiated a terrifying campaign of genocide, massacring hundreds of thousands of minority Tutsis (who had been given power by the departed Belgian colonists), while the rest of the world looked on and did nothing. Don Cheadle stars as Paul Rusesabagina, the hotel manager at the fancy Les Milles Collines hotel in Kigali. Paul is a Hutu, and a very successful businessman who smoothly greases the wheels, making powerful connections in all strata of Rwandan life. His wife, Tatiana (Sophie Okonedo of Aeon Flux), is a Tutsi. She urges Paul to use his influence to help local Tutsis, who are being harassed and beaten with increasing frequency, but Paul will only use the political capital hes built up to help his own family, if and when they need it. Soon enough, the violence escalates, and the Hutus begin their genocide of the Tutsis. European guests and staff at the hotel are flown out of the country, and Paul is left in charge. He finds that his conscience wont allow him to watch as the innocent are slaughtered, and before long, the hotel has become a well-appointed refugee camp. Paul is seen as a traitor by some, putting his life in danger, and the predicament of his guests grows more precarious every day, but despite good intentions on the part of a journalist (Joaquin Phoenix) and a UN peacekeeping colonel (Nick Nolte), the rest of the world is not eager to intervene and stop the massacre. Hotel Rwanda was directed by Irish filmmaker Terry George (Some Mothers Son), who co-wrote the script with Keir Pearson. The characters Rusesabagina and Colonel Oliver negotiating through a political impasse. In fact, the films depiction of events in Rwanda in the early 1990s is remarkably free of dramatic license. The narrative on ethnic conflict in Rwanda and the sequence of events is essentially sound (although it does imply that it was Hutu extremists who assassinated President Juvà ©nal Habyarimana, a thesis that remains contested). The early scenes in town and at the hotel re-create the mood, sights, sounds, and social relations of a small African capital as well as any Hollywood movie ever has. One quibble: like too many other accounts of the genocide, the story concludes with the arrival of the Tutsi rebels in Kigali, implying that the killings stopped then. This end makes dramatic sense but conveys a historical inaccuracy, since, alas, the country endured many more months of intense violence, including tens of thousands of reprisal killings. Tensions between the Hutu and Tutsi Peoples lead to a war in Rwanda, where corruption and bribes between politicians are routine. Paul Rusesabagina Don Cheadle, the manager of the Sabena Hà ´tel des Mille Colline is Hutu, but his wife Tatiana Sophie Okonedo, is Tutsi. His marriage is a source of friction with Hutu extremists, most prominently Georges Rutaganda Hakeem Kae-Kazim, a friendly goods supplier to the hotel who is also the local leader of Interahamwe, a brutal anti-Tutsi militia. As the political situation in the country worsens, Paul and his family observe neighbours being killed in ethnic violence. Paul curries favor with people of influence, bribing them with money and alcohol, seeking to maintain sufficient influence to keep his family safe. When civil war erupts and a Rwandan Army officer threatens Paul and his neighbours, Paul barely negotiates their safety, and brings everyone to the hotel. More refugees come to the hotel from the overburdened United Nations camp, the Red Cross, and orphanages. Paul must divert the Hutu soldiers, care for the refugees, be a source of strength to his family, and maintain the appearance of a functioning high-class hotel, as the situation becomes more violent Action Adventure, Art Foreign, Kids Family, Biopic, Politics Religion and Drama Two recurrent themes jump out at me from the movie Hotel Rwanda. The first, that everything has a price. Paul Rusesabagina pays for his families and neighbours freedom and life by bribing an army officer, even negotiating the price for each. He is able to purchase beer and scotch for the hotel from the distributor, as long as he is willing to pay the price demanded. He consistently bribes the army general for protection for the hotels occupants from the armed militia. And when the bribes run out, so does the protection. The second major theme is one of self-reliance, or absence of external help. Throughout the movie it is repeated that the west refuses to help or does not value the Rwandans enough to intervene in the genocide. The Wests refusal to intervene is seen when the UN peacekeeping force has orders to not use their weapons. Its seen in the size of the UN peacekeeping force, reduced to 260 men at the beginning of the genocide and civil war in 1994. In the movie this last reduction proved a false hope for the survivors holed up in the hotel. UN reinforcements arrive, only to evacuate many UN peacekeepers and foreign citizens from Rwanda and the hotel, respectively. There is also an episode where certain Rwandans who have foreign connections are granted visas to leave the country because of the intervention of their friends mostly from African nations. The contrast of this action to the wess non-intervention is stark. who you know becomes a factor in survival. The distributor where Paul purchas es supplies is a member of the Hutu militia. But because he knows him and has had a business relationship with him for years, hes able at a price to still secure supplies for the hotel residents. Emotional; mood: Disturbing, the music is unbearably fitting for the mood of the movie. Hotel Rwanda is a very disturbing film, and yet a very hopeful one as well, vibrant attire, and the smooth, accurate rendering of skin tones. Hotel Rwanda is the most inspirational film, about hope within a troubled society, still at peace, but he gradually shifts it to a dark tone as the movie goes on. Hotel Rwanda is a very disturbing film, and yet a very hopeful one as well, as it shows how amidst horrific brutality, a lone human being can demonstrate how an individuals willingness to make a stand can make a huge difference in the lives of many of his fellows. It is also an extremely powerful film, capable of inducing nightmares in those who watch it, as the horrific events depicted therein actually took place in the African country of Rwanda during the year 1994. Hotel Rwanda uses various rhetorical devices in order to express the difference between the initial happy moods of the movie compared to the gloomy mood the creators demonstrate the conflict begins. Some of the most effective rhetorical devices used are the music in the film as well as the comparison between the atmospheres of two similar settings. The objective of the creators was not only to show the audience what was happening in Rwanda, but to make them sympathize with the characters. With these rhetorical techniques, they are successful in doing so because they influence multiple senses in different ways. The music in Hotel Rwanda is one of the most effective rhetorical tools in any movie because it sets the mood without the need of visuals. In good movies this is necessary because it creates a mood using multi-modal techniques, which are proven to be more effective than if the argument was solely visual. Hotel Rwanda is an important and carefully crafted film well worth seeing. Set in Kigali, the capital city of Rwanda, during the genocide of April and May 1994. If you view this film in conjunction with reading holocaust in Rwanda. Hotel Rwanda is an important and carefully crafted film well worth seeing. Set in Kigali. We are here as peacekeepers not peacemakers. The purpose of showing this movie was to warn Thais to rethink the present political conflict here, which is damaging the Kingdom. Tensions between the Hutu and Tutsi Peoples lead to a war in Rwanda, where corruption and bribes between politicians are routine. Paul Rusesabagina and his hotel are the very symbol of hope.

Old Man and Sea Essay -- essays research papers

Perserverance, Courage, and Wisdom Used in Everyday Life Throughout a life, people have to overcome obstacle after obstacle to be successful in the world. Humans are thrown challenges day after day, week after week. Everyone must try hard at something to be truly happy in their life. In Ernest Hemingway’s novel The Old Man and the Sea, he used the marlin and the sharks as symbols, and gave Santiago certain character attributes to depict the perserverance, courage, and smarts needed to get through the ups and downs that life hands everyone. Santiago had gone 84 days without catching a fish and was about to surpass his previous record of 87 days, when there was a pull on his line. Santiago had finally caught a something. To make it even better, it was a marlin larger than his boat. Hemingway used this marlin to symbolize the struggle for life. Santiago was matched up against his perfect opponent to bring out the best in him. The marlin brought out his strength and courage to fight the fish for 3 days in his old age. Santiago had to overcome the fish to survive, to be a hero is his community and to himself. Towards the end of the story, Santiago told the fish, â€Å"I shouldn’t have gone out so far fish, neither for you nor for me. I’m sorry fish† (110). Santiago was telling himself the experience brought out so much strength and courage in him, but it was hard for him to accept the defeat of the sharks devouring the marlin.   Ã‚  Ã‚  Ã‚  Ã‚  One contrast to the marlin...

A Study into the Effect of Varying Length of Warm Up on Performance of 400 Metre Sprint The WritePass Journal

A Study into the Effect of Varying Length of Warm Up on Performance of 400 Metre Sprint Abstract A Study into the Effect of Varying Length of Warm Up on Performance of 400 Metre Sprint )   looked at stretch warm-ups performed for varying amounts of time before sprint. They found that sprints performed within 5 minutes of warm-up were adversely effected by sets of stretches, however their studies involved 10 and 20 metre sprints only, and their sample set contained only 16 athletes.  Ã‚   There are relatively few studies exploring.   Hajoglou et al (2005) look at the impact of warm up time, but upon performance in cycle trials. They found that 4-5 minute endurance cycling trials were performed better after warm up, but found no evidence for warm-up duration having an impact.  Ã‚   Arnett (2002) looked at the difference between prolonged and reduced warm ups, and found increased duration of warm up was not beneficial to performance,  Ã‚   but this study examined swim performance. Therefore, while a number of studies explore the types of warm-up activities which work best, less attention has been paid to the relationship between time spent on warm-up and performance.   Additionally, some studies use different types of athlete, and are hence less relevant to sprinters. For example, studies carried out amongst rugby players can offer only limited insights to sprint performance.   To the extent that existing studies look at sprint, they also tend to look at short sprint performance, typically 30m or less. In the light of this, it is felt that the current study will add new insights into   the understanding of how to achieve optimum sprint performance.  Ã‚   Not only has the link between warm-up time and sprint performance been under-investigated, there is no investigation at all of the impact of different warm up times on 400m sprint.  Ã‚   There seems to be mixed evidence about the impact of warm up generally on performance, both in sprint and other types of sport. The following research hypothesis will therefore be tested by the study: Length of time spent on warm up has an impact upon performance in 400m sprint. A number of research questions will be investigated in the study: Does length of time spent in warm up have an effect upon sprint performance? What length warm up time is associated with fastest sprint performance? What are the mechanisms linking warm up time and sprint performance? 3. Methodology This section sets out the way in which the research study will be carried out. It divides into logical subsections to cover the different areas involved. 3.1 Participants The study will involve 40 athletes.   For the purposes of this study, athletes are restricted to men and women aged 16-30 who take part in competitive running at least once a month, who are a member of a sports club or association, and who train daily for at least an hour.  Ã‚   The researcher will contact a number of sports bodies including local running clubs and the university running association in the first instance, to find suitable participants to take part.  Ã‚   Initially, contact will be made by the administrative secretary or similar by telephone or email to explain the purpose of the study, and to request help in finding suitable candidates to take part. Care will be taken to ensure that the sample is representative of the wider population of interest (sprinters), and that bias is avoided in the selection procedure (Monsen and Horn 2007). 3.2 Materials and Procedure The study will involve 40 athletes performing the same warm up routine. The routine includes jogging as well as dynamic and static stretching. Each athlete will perform a 5 minute warm up, then their performance running the 400 metres will be timed.   Two days later, the same athletes will be timed running, this time after a 10 minute warm up. This will be repeated twice, each time after two days, and each time increasing the warm up time by 10 minutes (to 20 minutes and 30 minutes).  Ã‚   The aim is to investigate which warm up time produces the same results. One issue with this approach is ensuring that conditions are equivalent on each day that the test is carried out. If weather conditions differ, this may cause differences in running speed (Hawley 2000).   Equally, diet variations or other variations personal to the athletes might cause changes in recorded running speed, but these are less of a problem as, unlike the weather, they will probably not affect all the athletes who take part.  Ã‚   One way of dealing with results being impacted by variables aside from the one tested would be to randomly assign athletes into four groups, each of these are tested on the same day, and each warms up for a particular length of time. However, this would reduce the sample size for each group, and larger sample sizes yield more reliable results (Ware and Brewer 1999).   The first procedure will therefore be adopted. Because the study involves human subjects, ethical considerations need to be observed to ensure that no one involved comes to any harm or gains unfair advantage by being included in the study. 3.3 Data Analysis The data will be quantitative in nature (that is, expressed as numbers rather than text).   It will be entered into a statistical computer programme, such as SPSS, in order to carry out descriptive and other statistical tests. The ANOVA test will be performed on the data. It is a   widely used statistical procedure which compares data from investigations where there are more than 2 conditions. Rather than using several t-tests to compare means, the ANOVA test compares all sets of results, to indicate whether the results differ significantly from condition to condition (Brace et al 2006). 4. Conclusion The above has given an overview of the methodology and relevant literature for this proposed research study, looking at whether variations in warm up time have an impact upon performance for athletes completing a 400 metre sprint. 4.

The Role of Typological Universals in SLA Essay

The Role of Typological Universals in SLA - Essay Example All humans learn their first language in the same way. Firstly through a preliminary stage of prelinguistic development and 'babbling' followed by a single word stage, and then a two-word stage. Simple sentences follow after this before the 'embedding' process is finalized through the use of complete sentences. There are a number of absolute universals that have characteristics which hold for all languages. The most powerful universals take the form of hierarchies (an ordered list). Below are examples of Color, Vowel and Animacy hierarchies: There are many ways knowledge of universal typologies can aid SLA but one important way could be termed 'The Iceberg Effect'. It can be difficult to learn a second language if you have scant knowledge of the structure and grammar of your own language. Although the L1 and L2 might be vastly different, they are still linked through the brain of the speaker. In understanding one's own language first, we then develop a framework for comparison. When we make a comparison we understand the perils of 'direct translation' from one language to another. While we see similarities in the use of certain tenses, articles, pronouns etc. we know that there are many instances when the two languages have very little in common. This helps a student to gain the 'iceberg effect', whereby one's knowledge of a subject is directly related to deeper background knowledge. Although perhaps never revealed, the hidden part of the iceberg backs up and cements SLA. The Role of Typological Universals in SLA Typological Universals have a vital role in Second Language Acquisition (SLA). Typological Universals can be defined as the 'notion that human languages necessarily share important, formative, properties'.1 However, this notion can both aid and hinder SLA, as in admitting that there are certain universals which link the native language (L1) with the second language (L2), one must also remain aware of how greatly languages can differ. Being aware of the differences means avoiding direct translation from L1 to L2. Assuming that the L2 works on the same structural principles as your native tongue will ensure you make numerous grammatical, syntactical and vocabulary errors. Research into Typological Universals 'aims to establish the limits within human language'.2 Study into this subject sees the world's languages almost as a single organism with various overlapping areas between the languages closest to them in 'roots' as well as 'universal links' with all other world languages. No mat ter how diverse, all languages are connected by common principles - these are Typological Universals. In the introduction to Typology & Second Language Acquisition, Anna Giacalone Ramat stresses how 'a basic connotation of typology is cross-linguistic comparison: implicational universals which are crucial in order to create a typology of languages of the world cannot be discovered or verified by observing only a single language'. Giacolone Ramat 2003, p.1) In 1270 Roger Bacon wrote that 'grammar is substantially one and the same in all languages, despite its accidental variations'. (Thomas 2004, p.2) While the above
