Exercise Physiology for Risks and Mitigation - myassignmenthelp
Question: Discuss about theExercise Physiology for Risks and Mitigation. Answer: Purpose of the study and expectation The purpose of this study is to learn of effects of sleep deprivation on exercise or effects of exercise after sleep and all these based on performance. My expectation was to find out whether it is true that enough sleep is important to sustain peak endurance during exercise for better performance as coaches and athletes agree on this factor. Does sleep deprivation really has any direct effect on exercise and performance? Explanation of the outcome Adequate sleep is important to sustain peak endurance during exercise for better performance as coaches and athletes agree on this factor. However, the physiological and psychological direct effects of sleep deprivation are yet to be established. There is no proper measurement of effects of sleep deprivation on exercise or effects of exercise after sleep. Sleep deprivation results to dramatic psychological changes in terms of performance on visual and memory task decreasing as well as reaction to time (Walter 1978). However, in comparison to physiological changes, sleep loss does not have an apparent effect on a person physiologically. The connection between sleep loss and its effects on performance is yet to be proved and be agreed on therefore making the findings to be inconclusive and at conflict. There is no proper measurement of effects of sleep deprivation on exercise or effects of exercise after sleep and all these based on the overall performance. It is noted that physiologic al correlates of exercise performance can be affected by sleep deprivation .Variety of studies have been made concerning sleep deprivation and its effect on performance and exercise but none has had an established conclusive answer (Doran 2001). Studies and explanation of this hypothesis The two major studies that I used to explain my hypothesis is; 1. Exercise after sleep deprivation whereby I found out that as much as enough sleep is important to sustain peak endurance during exercise for better performance as coaches and athletes agree on this factor. However, the physiological and psychological direct effects of sleep deprivation are yet to be established. There is no proper measurement of effects of sleep deprivation on exercise or effects of exercise after sleep. Sleep deprivation results to dramatic psychological changes in terms of performance on visual and memory task decreasing as well as reaction to time. However, in comparison to physiological changes, sleep loss does not have an apparent effect on a person physiologically. In this study we look at how physiological effects of sleep loss have an influence over exercise. Various exercises from mid to maximal intensities were done so as to measure the responses to cardiovascular, metabolic and respiratory p rocesses (Dempsey 1977). 2. The second study was on one night of sleep deprivation decreasing treadmill endurance performance. Here the aim was to test this hypothesis and investigate the effects of one night sleep deprivation on endurance in the running performance. After an experiment was performed, my hypothesis was supported and shows that with the 30 hours of sleep deprivation, there was a major effect on endurance performance of running in the treadmill. Another discovery was that participants perception of effort had an effect on performance as there was decrease in the endurance performance following the night without sleep (Brodan et al 1969). Participants The participants in my study were eleven recreational active and healthy males were picked randomly to complete the experiment in random trials separated by 7 days. One after normal sleep and another following a 30 hour without sleep. Variables in my study This study has both independent and dependent variables. The independent variable in this study is whether the participants performance and exercise will be affected by sleep deprivation. The dependent variable is the effects of these exercises on the participants cardio-respiratory, thermoregulatory and perception of effort responses during intense exercise. Study approach This experiment was done after an acute sleep deprivation process of 30 hours and results taken before, during and after the exercises. The experiment was based on random trials separated by 7 days. One after normal sleep and the other was following a 30 hour without sleep. Breathing was measured by use of a spirometer. The expired gas samples from breathing were put into test and it was noted that after the exercise the breathing effort was labored. An experiment was done to eleven active and healthy male participants to show submaximal exercise after sleep loss. The experiment was to investigate the effects of sleep deprivation and the after effects manifested after the deprivation. The exercise was to take seven days and the participants were to be monitored every day for the seven days. Before the exercise the participants were familiarized with the experiment procedures before undertaking the exercise. Daily exercises were required for the seven day experiment to see both physio logical and psychological responses of each participant (Doran 2001). Food was reduced to a light breakfast which the participants ate every four hours before each experiment. All exercises were done on a treadmill and speed and distance was tested as well as skin temperatures and heart rates. The 30 hours of sleep deprivation had limited effect on cardio-respiratory and thermoregulatory processes even after intense running exercise. The heart rate decreased by 7-8 beats min during the distance test and oxygen intake was also increase due to intensity of the exercise and due to sleep deprivation. Risks and mitigation of those risks The risk that was involved in this test was the prolonged sleep deprivation of 30 hours on the participants and subjecting them to very intense treadmill exercise for seven days. These intense approaches could affect endurance performance of the participants. However, the risks were mitigated by randomly separating the trials and splitting the seven days by incorporating rests in between. The participants were also health males who signed a consent contract to undertake the trial. The participants were also provided for estimated energy requirements and control nutritional and hydration status. Water was provided equaling to 35 ml and energy requirements were also available and enough (3280 (209) kcal d-1). Findings by use of a table on ratings of perceived exertion (RPE minimum rating6, maximum 20) during light, moderate and heavy exercise before and after sleep deprivation. Experimental series Control series Day 1 Day 2 Day 3 Day 1 Day 2 Day 3 Light exercise RPE 6.3 6.9 6.3 6.4 6.3 6.2 Moderate exercise RPE 10.5 12.3 11.0 10.9 10.7 10.6 Heavy exercise RPE 14.4 17.1 15.6 15.2 14.9 14.7 During submaximal exercise, sleep deprivation left no changes in all physiological variables as shown in the above table. During maximal exercise, sleep deprivation did not change heart rate and did increase on the perceived exertion ratings in the moderate and heavy exercise (Copes 1972). It is clear to note that the return of perceived exertion to near control levels following a night of sleep shows that recovery from acute sleep deprivation may be rapid. Experiment findings Sleep deprivation mostly does not affect physical performance but has a direct effect on human cognitive and motor functioning. This has been proved before that sleep deprivation is more psychological than it is physiological. Human cognition is more psychological and motor performance is more physiological. Sleep deprivation has effects on performance and physical exercises and it affects the performance of a person engaging in exercise and the recovery process. Many athletes are affected by sleep and it results to effects on performance and post exercise recovery. There is substantial scientific evidence showing a connection between sleep, metabolic functions and cognitive processes. Sleep deprivation is majorly linked to cognitive impairment which is mostly a psychological function. Sleep deprivation also affects negatively the metabolic functions and physiological process Armington 1959). Enough sleep has a positive impact on optimal performance as many athletes, coaches and trai ners have confirmed. However, more sophisticated methodology is needed to prove this fact as little is known on the connection between sleep and post-exercise recovery and performance. It is noted that physiological correlates of exercise performance can be affected by sleep deprivation. More studies are being made thoroughly to investigate on the connection of sleep to training, PER and performance in exercise (Spielgel 1999). Study Results After the study I got results that agreed with what was in the literature a number of people may be prone to exposure to sleep loss or sleep deprivation based on different situations and circumstances. Despite the claims from different studies made that adequate and quality sleep is important for maximum performance, there is no substantial evidence to prove the same. There is little or no proof to tie sleep deprivation effects on exercise performance. It is noted that physiological correlates of exercise performance can be affected by sleep deprivation. Sleep deprivation can be caused by a variety of factors such as cardiovascular, metabolic and respiratory processes. Sleep deprivation results to dramatic psychological changes in terms of performance on visual and memory task decreasing as well as reaction to time. However, in comparison to physiological changes, sleep loss does not have an apparent effect on a person physiologically. Sleep deprivation mostly does not affect physica l performance but has a direct effect on human cognitive and motor functioning. This has been proved before that sleep deprivation is more psychological than it is physiological. Human cognition is more psychological and motor performance is more physiological. . It is possible to endure and tolerate intense exercises even with sleep deprivation in all situations through increased perceived efforts. Many athletes are affected by sleep and it results to effects on performance and post exercise recovery (VanHelder 1989). . Acute sleep deprivation reduces exercise tolerance and therefore affects performance coupled with other various practical situations. These situations that can cause sleep loss are such as military personnel on sustained operations, workers who work on shift patterns and also athletes who travel through different time zones as well as people who suffer from acute insomnia. However, studies regarding performance in exercise after sleep loss are yet to be conclusive a nd accurate. Limitations on experiment and remedies During my experiment I faced one limitation and that was conclusive and accurate information regarding effects of sleep deprivation and performance. If I was to do the experiment again I would ensure I have enough information on how acute sleep deprivation could have effect on obtaining maximum performance in exercise. More proof and added information is required to connect sleep deprivation and its effect on physical performance and human cognitive and motor functioning. This will be able to answer if sleep deprivation is psychological or physiological. References Armington JC and L. L. Mitnick. Electroeneephadogram and sleep deprivation. J. Appl.

Argumentative and Persuasive Current State Essay Example For Students
Argumentative and Persuasive Current State Essay Laws on Human Cloning Cloning Argumentative Persuasive EssaysCurrent State Laws on Human Cloning California Cal. Health Safety Code, 24185 to 24189. Bans efforts to create a human being by utilizing somatic cell nuclear transfer for the purpose of, or to implant, the resulting product to initiate a pregnancy that could result in the birth of a human being. Ban is to expire January 1, 2003 unless extended by legislature. Louisiana La. Rev. Stat. Ann. tit. 40 1299.36 to 1299.36.6. Forbids any person to clone or attempt to clone a human being, and forbids a health facility or agency to allow any individual to clone or attempt to clone a human being in a facility owned or operated by the health facility or agency. Clone is defined as in California law, to involve an intent to initiate a pregnancy. However, a separate state law prohibits intentionally destroying a viable fertilized ovum, and requires that no in vitro fertilized human ovum will be farmed or cultured solely for research purposes or any other purposes. La. Rev. Stat. Ann. tit. 9, 129, 122. Whether this prohibits use of cloned embryos for research depends on how courts will interpret the phrase fertilized human ovum. Michigan Mich. Comp. Laws 333.16274, 333.16275, 750.430a. Forbids any individual to engage in or attempt to engage in human cloning, applying civil penalties (up to a $10 million fine) and criminal penalties ($10 million fine and up to ten years in prison). Human cloning means the use of human somatic cell nuclear transfer technology to produce a human embryo. 333.16274(5). This law clearly forbids creating a cloned human embryo for any purpose, including research. A separate state law also forbids using a live human embryo for nontherapeutic research if the research substantially jeopardizes the life or health of the embryo Performing such research is a felony. 333.2685 (1), 333.2691. Rhode Island R.I. Gen. Laws 23-16.4-2 to 23-16.4-4. Bans use of somatic cell nuclear transfer for the purpose of initiating or attempting to initiate a human pregnancy, as well as the creation of genetically identical human beings by dividing a blastocyst, zygote, or embryo. The law seems to ban cloning by nuclear transfer only if done to initiate a pregnancy. However, a separate law prohibits the use of any live human fetus, whether before or after expulsion from its mothers womb, for scientific, laboratory research, or other kind of experimentation. R.I. Gen. Laws 11-54-1(a). An analysis commissioned by the National Bioethics Advisory Commission interprets this law to ban research on in vitro embryos altogether, apparently including cloned embryos. NBAC, Ethical Issues in Human Stem Cell Research, Vol. II, pages A-4, A-10. South Dakota S.D. Codified Laws 34-14-16 to 34-14-20. Under this law it is a crime to conduct nontherapeutic research that destroys a human embryo or that subjects a human embryo to substantial risk of injury or death. Nontherapeutic research means researc h that is not intended to help preserve the life and health of the particular embryo subjected to risk. A person also may not use for research purposes cells or tissues that the person knows were obtained by performing such harmful nontherapeutic research. Human embryo is defined as a living organism of the species Homo sapiens at the earliest stages of development (including the single-celled stage) that is not located in a womans body. The law applies to human embryos regardless of whether they arose from fertilization, so it certainly bans experimental cloning in which human embryos are destroyed, as well as any use of cells or tissues obtained by destroying them. Given the current survival rate of human embryos created by cloning, it also has the effect at present of banning the basic research in human cloning designed to prepare the way for attempts at cloning for live birth. Virginia Va. Code Ann. 32.1-162.21, 32.1-162.22. The law forbids human cloning, defined as the creati on of or attempt to create a human being by transferring the nucleus from a human cell from whatever source into an oocyte from which the nucleus has been removed. It also forbids anyone to implant or .u31fc4c8c60081b631a067ae2946d7a87 , .u31fc4c8c60081b631a067ae2946d7a87 .postImageUrl , .u31fc4c8c60081b631a067ae2946d7a87 .centered-text-area { min-height: 80px; position: relative; } .u31fc4c8c60081b631a067ae2946d7a87 , .u31fc4c8c60081b631a067ae2946d7a87:hover , .u31fc4c8c60081b631a067ae2946d7a87:visited , .u31fc4c8c60081b631a067ae2946d7a87:active { border:0!important; } .u31fc4c8c60081b631a067ae2946d7a87 .clearfix:after { content: ""; display: table; clear: both; } .u31fc4c8c60081b631a067ae2946d7a87 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u31fc4c8c60081b631a067ae2946d7a87:active , .u31fc4c8c60081b631a067ae2946d7a87:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u31fc4c8c60081b631a067ae2946d7a87 .centered-text-area { width: 100%; position: relative ; } .u31fc4c8c60081b631a067ae2946d7a87 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u31fc4c8c60081b631a067ae2946d7a87 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u31fc4c8c60081b631a067ae2946d7a87 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u31fc4c8c60081b631a067ae2946d7a87:hover .ctaButton { background-color: #34495E!important; } .u31fc4c8c60081b631a067ae2946d7a87 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u31fc4c8c60081b631a067ae2946d7a87 .u31fc4c8c60081b631a067ae2946d7a87-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u31fc4c8c60081b631a067ae2946d7a87:after { content: ""; display: block; clear: both; } READ: Styrofoam and Clam Shells as Tiles Essay

The Food Impact on Health
Foods being consumed in the modern world contribute a lot to obesity and other diet-related diseases such as cancer and hypertension. In the UK, for instance, many of the edible products sold in the supermarkets are contaminated thus affecting the health of the people and most products, especially pastry products, have a lot of sugar, fat and salt. This can easily lead to diseases such as obesity due to lots of fats and sugars (Carpenter and Finley 215).Advertising We will write a custom article sample on The Food Impact on Health specifically for you for only $16.05 $11/page Learn More Supermarkets in the UK influence high levels of obesity and health levels because it has been reported that most of them sell cakes and quiches that are made with eggs. The Food Standard Agency says that some of the manufacturers in the UK use eggs that have been contaminated with dioxins to make most of their edible products thus leading to health problems. The products do not last for long thus making them to be eaten just before their sell- by dates. However, the Food Standard Agency (FSA) highlighted that mixing of the eggs reduces the dioxins level hence no risk to oneââ¬â¢s health. Contaminated liquid eggs came from Europe intended to be used in products like pastries and mayonnaise. Similarly, there was poultry feed that was sent to Germany for use in the pig farms, which had already been contaminated by poisonous dioxins. FSA said that ââ¬Å"These eggs were mixed with other non-contaminated eggs to make pasteurized liquid egg. This pasteurized liquid egg has been distributed to the UKâ⬠(Behrman 30). Dioxins are dangerous chemicals originating from processes in the industries or burning of waste products. They contribute to diseases such as cancer and highly affect pregnant women. A report presented by the food commission showed that food products sold by Tesco and Sainsburyââ¬â¢s supermarkets have a lot of sugar, salt and fat, w hich is not healthy for consumption. The foods also promote obesity since the customers do not know which foods are healthy to them especially when they are being sold at a low price. There is a commission that proposed that Tesco and Sainsbury supermarkets should use various colors on the packs to indicate the levels of sugar, fats and salts. FSA insisted on the Tesco to use red lights on the sultana bran flakes because they contain high levels of salt and sugar. Similarly, sunflower would also show red lights on the pack due to its high levels of fat and salt (Slater 12). This clearly shows that most of the products are not healthy for human consumption and they are likely to cause obesity due to the high levels of saturated fats. Customers tend to go for the cheapest foods since most of them do not have the idea of the ingredients that make these products (Marion 88). Most of these products are affordable, such as the cakes and junk food, but are very unhealthy to the body since they have a lot of sugar and fat (Goodwin 11).Advertising Looking for article on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Evidently, a healthy diet should contain, though expensive, many fruits, green vegetables, unprocessed foods, foods with less fat and less sugar. The government in the United Kingdom as well as other countries have has tried to improve the consumption of healthy foods by making the supermarkets to reformulate their products as well as promoting healthier products since they are very expensive. In France, for instance, the Angers court of Appeals has made an opinion on the vitamin C and supplements on food products to be sold in the supermarkets and hypermarkets. Their aim is to ensure that healthy and hygienic products are available in the supermarkets.â⬠Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet becaus e it reduces chances of obesity and the diseases related such as hypertension and diabetesâ⬠(Galdston 54). In Spain and Italy, the supermarkets have health food stores that have different organic and vegetarian items. Additionally, many vegetarian restaurants are also available and sell products made of soy and wheat gluten. So, in France, Spain and Italy, there is a wide variety of healthy products in the supermarkets as compared to the United Kingdom. A survey conducted in 1999 on the number of obese people in the four countries showed that France had the least number of people with 15% followed by Italy with 18%, then Spain with 23% while UK lead with 50% people who had obesity. This shows that obesity is very common in UK due to the unhealthy eating habits. ââ¬Å"Interesting that France, Spain and Italy all have a low rate of obesity, maybe they are used to eating more healthy foodsâ⬠(Mead 56). To achieve a healthy diet, one must eat different variety of foods .Supe rmarkets and hypermarkets have a major role to play in assisting people to eat a balanced diet by offering a great variety of products (Smith 145). Customers decide on what to eat; therefore, they just require good ideas on what to select. The ingredients of every product should be well and clearly labeled on the pack to eliminate confusion.

How Frosts, Freezes, and Hard Freezes Differ
How Frosts, Freezes, and Hard Freezes Differ Just asà the sprouting of tender green leaves is considered one ofà theà first signs of spring,à the first frost of the cool season signals that fall has officially settled inà and thatà winter isnt far behind. How Frost Forms Look for frost to form when these atmospheric conditions are present: clear nighttime sky conditions,at or below freezing air temperatures at the surface, andcalm winds (speeds less than 5 mph (1.6 km/h)). Clear skies and calm winds allow for daytime heating to escape the Earths surface. This heat out into the upper atmosphere and outer space. Whats known as a temperature inversion layer forms (temperatures increase rather than decrease as one travels upward in the air), and allows cold air to settle near the ground. As the ground temperatures cool to below freezing, what water vapor resides in the air ices up onto exposed surfaces thus forming frost. The terms frostà and freezeà are usuallyà mentioned together, however,à they describe two veryà different happenings. Freezes Imply Lows Near 32 F A freeze means that widespread temperatures are expected to fall to or below the freezing mark (32 à °F). A hard freeze implies that widespread temperatures are forecast to fall below freezing (most NWS offices use 28 à °F as the threshold criteria) for long enough to seriously damage or kill seasonal vegetation. For this reason, hard freezes have earned the monicker killing frosts. A hard freeze usually occurs when a cold air mass moves into an area and brings temperatures ofà 32à °F or below. Thisà freezing cold air is often blown by winds, orà advected,à into an area, and may, therefore, be associated with light or variable wind speeds.à Frosts Imply Lows Near 32 F and Moist Ground Air Frost, on the other hand, has to do withà the formation of ice crystals on the ground andà on other surfaces. It occursà in the absence of wind, and theà freezingà temperatures are the result of radiational cooling.à Whereas freezes have to do with air temperature alone, any weather alert having to do with frost not only implies that temperatures are expected to be 33 to 36 à °F, but also that the amount of moisture residing in the air at these temperatures is adequate for frost formation near the surface.à à Can a Freeze Occur Without Frost Forming? Yes, freezes can happen even if a frost doesnt. This seems odd since it takes colder temperatures (at least 32 degrees) to get a freeze. It seems like youd get a frost (which requires temperatures of 33 to 36 degrees) first. It would make sense that moisture would frost before freezing except that frost is less likely to form when the dew point temperature falls below the mid-20s. This is because, at such cold temperatures, there just isnt enough moisture in the air for significant frost formation despite the fact that cold enough temperatures are in place to support it. Frost Freeze Weather Safety The majority of individuals dont notice frost, except when it forms on theirà car windowsà andà delays their morning departure by severalà minutes time. However, agriculturists and farmers considerà it is a critical weather event. This is becauseà most plants (except a few varieties thatà actually need a hard freeze to coax seeds into germination)à are extremely sensitive to it. A frost too early,à or too late,à in the growing season can result in crop failure and a shortage of food supply. There are a number of ways to protect against frost damage, including: Coverà plants. When plants are covered, frost can settle on a barrier rather than on the vegetation directly. For this reason, plants not in direct contact with the covering material have the highest level of protection. Woven fabrics, such as sheets, work best and can offer 2à ° to 5à °F of added warmth. Potted plants should be covered or brought indoors.Irrigateà the soil and plant leavesà before the frost arrives.à This might sound strange considering water will freeze when theà temperature drops, but rest assured there is a method to this madness.à Moist soil is capable of holding up to four times more heat than dry soil. Likewise, if fruit trees have begun their yield, spraying the outside skin with water can actually help keep internal temperatures above freezing by allow the outside to freeze and create an insulating barrier.Keep plants watered to fight off drying from cold winds.Bring pets indoors whenever extreme cold is expected.Cover exposed pipes and outdoor faucets to discourage freezing.

Definition and Examples of Person in English Grammar
Definition and Examples of Person in English Grammar In English grammar, the category of personà identifies the relationship between a subject and its verb, showing whether the subject is speaking about itself (first personI or we); being spoken to (second personyou); or being spoken about (third personhe, she, it, or they). Also called grammatical person. Personal pronouns are so called because they are the pronouns to which the grammatical system of person applies. Reflexive pronouns, intensive pronouns, and possessive determiners also show distinctions in person. Examples and Observations A widely attested type of verbal inflection in human language involves persona category that typically distinguishes among the first person (the speaker), the second person (the addressee), and the third person (anyone else). In many languages, the verb is marked for both person and number (singular or plural) of the subject. When one category is inflected for properties (such as person and number) of another, the first category is said to agree with the second. . . .Modern English has a [comparatively] impoverished system of person and number agreement in the verb, and an inflectional affix is used only for the third person singular in the non-past tense.à (William OGrady, et al. Contemporary Linguistics: An Introduction. Bedford, 2001)I amYou areWe are Australian.(B. Woodley and D. Newton, I Am Australian)I am he as you are he as you are me and we are all together.(John Lennon and Paul McCartney, I Am the Walrus) The Three Persons in English (present tense) First person I see great things in baseball.(Walt Whitman)We see things as we are.(Leo Rosten) Second person You see things, and you say Why?(George Bernard Shaw) Third person She sees more hospices and sink estates than most people.(Prince Andrew)The traveler sees what he sees; the tourist sees what he has come to see.(G.K.

One should never do anything that one cannot talk about after dinner.(Oscar Wilde, The Picture of Dorian Gray, 1890)Love is not blind: it sees more, not less.(Julius Gordon)They see me as some sort of pathetic character.(Mike Tyson) The Forms of Be Be is unique among English verbs in having three distinctive person forms in the present tense (am, is, are) and two in the past tense (was, were). Other verbs have a distinctive form only for the third person singular of the present tense (e.g., has, does, wants, etc., as opposed to have, do, want, etc.).

Transformed Worldviews Research Paper Example | Topics and Well Written Essays - 3000 words
Transformed Worldviews - Research Paper Example These values had been instilled in oneââ¬â¢s persona early during oneââ¬â¢s stage of child development and growth. It was handed down from generation to generation as documented among the Ten Commandments: ââ¬Å"Thou shalt not bear false witness against thy neighbourâ⬠(Holy Bible, New International Version, 2011). Thus, the verse stressed the importance of not telling lies and adherence to the truth. The modernistââ¬â¢s view is similar to oneââ¬â¢s personal viewpoint. One actually gained knowledge of the truth from this view. In the reading entitled ââ¬Å"Idolatry of Noveltyâ⬠written by Lynn Gardner, the author emphasized that truth is actually anti-thetical with the acceptance of alleged false teaching: ââ¬Å"'Doing truth' (or 'acting truly') is an Old Testament expression used especially when fidelity between two parties is the subject. Whether spoken or expressed in action, the truth is never to be dissociated from love." "Grace and truth" came through J esus Christ (John 1:14, 17)â⬠(Gardner, n.d., pp. 15-16). Likewise, truth, as asserted here, reverts from the source in the Holy Bible: as emanating from Jesus Christ; and the teachings relayed, communicated, and documented through the Bible attests to the need to adhere to ethical, moral, and legal standards which conform to truth, based on facts and reality. In addition, Packer (1993) averred that truth in the Bible means ââ¬Å"stability, reliability, firmness, trustworthiness, the quality of a person who is entirely self-consistent, sincere, realistic, undeceived. God is such a person: truth, in this sense, is his nature, and he has not got it in him to be anything elseâ⬠(p. 127). Therefore, God is the perfect embodiment of truth because in His Divinity, He was noted not be have any ability to lie... Different people gain knowledge about God through diverse modes and medium. From the material from class texts and discussion, one acknowledges that people learn about God from stories, narrations and testimonies of family members and relatives; from theology or religion courses; through the scriptures, specifically through the teachings in the Holy Bible; through attendance of religious practices and obligations (masses for the Catholics); and through personal interests and intentional pursuits. Knowing about God comes from information gathered or collected from external sources or from the experiences of other people who shared the information to others. As emphasized, ââ¬Å"ââ¬Å"knowingâ⬠God is of necessity a more complex business than ââ¬Å"knowingâ⬠another person, just as ââ¬Å"knowingâ⬠my neighbor is a more complex business than ââ¬Å"knowingâ⬠a house, or a book, or a language. The more complex the object, the more complex is the knowing of itâ⬠. The critical aspect of the knowing about God is the contention that ââ¬Å"knowing them is more directly the result of their allowing us to know them than of our attempting to get to know themâ⬠.

Methods - Research Proposal Example It finally identifies an ideal model for the presentation of this data to various stakeholders to ensure that they give their economic and social support for the regeneration of Dundeeââ¬â¢s Central Waterfront area to a world-class city. The research ends with the description of deliverables that must be presented by Dundeeââ¬â¢s Central Waterfront to various stakeholder groups. Keywords: Dundee City, Dundee Central Waterfront, Investors, Stakeholders, Competitive City Introduction Dundee City is embarking on a project to expand Dundeeââ¬â¢s city centre down to the Central Waterfront Area (Dundee Waterfront Vision). The Dundee Waterfront area encompasses four main sections of the city of Dundee located near they Tay Riverside (Dundee Waterfront Business Current Project)This project is to create a new iron grid system reminiscent to the connections made by the Romans in the city over 1,500 years ago. It also seeks to improve numerous facilities in the city and also go further to regenerate various elements of the city to place it in the category of other competitive European and Global cities (Dundee City Official Website). The project started in 2001 and is expected to end in the year 2031. Currently, there is the need for investors to sink capital into the various projects to create the background for future development of the city. Also, there is the need to attract and promote the city positively before its stakeholders, particularly present and future residents. Research Objectives McMillan & Weyers (2010) states that every academically recognised research project must have a set of clearly defined objectives that the research will be based upon. The purpose of this research are to: 1. Create the definitive platform for the critical analysis of stakeholders to the Central Waterfront Area development project at this present point in time. 2. Identify optimum uses of sites for investors, settlers and stakeholders 3. The description of the data collec tion methods to be used for the collection of preliminary data for the project 4. The identification of investor and other stakeholder presentation model Literature Review Bryman, (2008) states that for an academic research work to have the relevant credibility and acceptability in the world of academia, there is the need for the researchers to review analyse and present groundbreaking definitions, models and system through secondary literature. First of all, the literature review of this research will be based on the elements and features of a competitive city. From preliminary analysis, the paper should focus on the sector approach, institutional approach and conditions for settlement defined by Sako & Murie, (2010) to lay out the potential and optimum land use type that the presentations to stakeholders must dwell upon. The sector approach involves the zoning of city centres being regenerated optimally between creative industries and knowledge intense industries. The creative ind ustries include arts, media, entertainment, creative business services, publishing, advertising and designing. This will ensure that the city will be promoted in other places where consumers will use these patents that are produced in the city in question. Knowledge
