50 Year of US Policy in the Middle East Essay Example | Topics and Well Written Essays - 1500 words

50 Year of US Policy in the Middle East - Essay Example The biggest asset of Middle East is the amount of oil that is concentrated in the region, which has simultaneously also emerged as one of the biggest problems. Therefore the Western population is highly accustomed to the propaganda of the Middle Eastern regions, and this has also brought Islam in the middle. It was especially prominent during the European colonial times, which was also exacerbated by Edward Said in his famous book, â€Å"Orientalism†. The way it has been negatively stereotyped has provided tremendous justification for involvement and also in ensuring a certain level of stability for the interests of powers that are present in the region (Shah, 2). Another issue, which is also pivotal to Middle East, is racism and cultural stereotyping that has become very concentrated. There are certain war films that depict an Islamic or Arab group as bad, which clearly show the current conflicts etc. A bad guy is very often an Arab from one of the rogue states and because of the 9/11 attacks perpetrated against the United States and also the War on Terror; it’s very likely that this description will continue. Another huge problem is that to maintain their dominance and supremacy in the Middle Eastern, the West has also put a lot of power, money and influence in the hands of corrupt Arab leaders, and consequently collaborated in the overthrow of those people who were seen as a threat to their interests. Furthermore, it has contributed a great deal in keeping the populations at bay, for the wealth, power and militarization of the elite class. It is also said to be done for combating the phenomena of communism.

Statistics in Business Essay Example for Free

Statistics in Business Essay Statistics is the science of learning from data, and of measuring, controlling, and communicating uncertainty; and it thereby provides the navigation essential for controlling the course of scientific and societal advances. Statisticians apply statistical thinking and methods to a wide variety of scientific, social, and business endeavors in such areas as astronomy, biology, education, economics, engineering, genetics, marketing, medicine, psychology, public health, sports, among many. Statisticians provide crucial guidance in determining what information is reliable and which predictions can be trusted. They often help search for clues to the solution of a scientific mystery and sometimes keep investigators from being misled by false impressions. Some examples that statistics are used are Statistics also provide the reasoning and methods for producing and understanding data. Statisticians are specialists, but statistics demands they be generalists, too. One advantage of working in statistics is that you can combine your interest with almost any other field in science, technology, or business. Another is Studies of the environment require data on the abundance and location of plants and animals, on the spread of pollution from its sources, and on the possible effects of changes in human activities. The data are often incomplete or uncertain, but statisticians can help uncover their meaning. One last example is the future of many industries and their employees depends on improvement in the quality of goods and services and the efficiency with which they are produced and delivered. Improvement should be based on data, rather than guesswork. More companies are installing elaborate systems to collect and act on data to better serve their customers. Statisticians must know more than statistics. A statistician who works in medicine or in a manufacturing plant or in market research must learn enough medicine or engineering or marketing to understand the data in their setting. Statisticians need the ability to work with other people, to listen, and to communicate. References; http://www.amstat.org/careers/whatisstatistics.cfm

Movie Rating :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Going to the movies is a favorite past-time event of American lives. A long time ago, however, there wasn’t any rating system. Making one seemed like a good idea at the time. Today, the system is still the same way and doesn’t fit today’s changed time. Therefore, the movie rating system should be revised because the current rating system is outdated.   Ã‚  Ã‚  Ã‚  Ã‚  Today’s kids are growing up faster and maturing at a faster rate than ever before. Twenty years ago it would be impossible to show breasts in a PG-13 movie. Today, kids are being taught the fasts of life younger than anyone could of imagined. This is all due to older brothers, the Internet and schools teaching kids about sex at the age of twelve. If everything else is changing except the rating’s no one is going to obey the law.   Ã‚  Ã‚  Ã‚  Ã‚  There are a total of four ratings that they show at most cinemas: G, PG, PG-13, and R. One would think that with so many different types of movies, there would be more ratings. Movies today have a very complex storyline and don’t want to give away any of the movie in the commercial. If there were more ratings you can tell what kind of movie it is and what is shown in the movie. For Example, the movie A.I. (directed by Stephen Speilberg) would be D_L-SC. This is because the movie is a drama, has language and has sexual content. If you saw that in a commercial rather than PG-13, you would have a better idea on if you wanted to see this movie or not.   Ã‚  Ã‚  Ã‚  Ã‚  Next, if this kind of rating took place then it could become universal and more socially excepted than every country with it’s own system for rating. Imagine, you can go to other countries (Europe perhaps) and watch movies made in English there. This might send some sort of bond between countries in rivalry. If the rating system is more universal then DVD players won’t need to have region block outs. This would enable people to buy a regular DVD player and watch movies from other countries. Plus, this would save the manufacturer money by not having to put more money into a region block out chip. This would also help out people buying DVD players by having them become cheaper. If we could watch movies from other countries, that would encourage us to expand our horizon on movies from other countries.

Romeo and Juliet Dramatic Effects

Analyse the dramatic importance of Act 3 Scene 5. Act 3 scene 5 is of huge dramatic importance as it is pivotal to the plot of the play. Act 3 scene 5 takes place the morning after Romeo and Juliet have spent their first night together following their marriage. In the first part of the scene, they are very happy and also very romantic as Romeo says â€Å"How are you, my love? † This shows that Romeo cares for Juliet and it also shows how much love, Romeo has just been banished from Verona for killing Tybalt and is preparing to leave.This makes Juliet very upset as they haven’t even spent a day together. The nurse comes to warn them that Juliet’s mother is coming to see her to discuss her marriage to Paris. After Romeo has left, Juliet bursts into tears. When Lady Capulet arrives, Juliet cries even more but Lady Capulet thinks she is crying because of her cousin’s death. Lord Capulet explodes with anger when he hears that Juliet disagrees with the marriage. The nurse unexpectedly advises her to marry Paris. The key themes highlighted in this scene are: happiness, love, parental conflict, anger and sadness.In this scene we learn a great deal about the characters of: Romeo, Juliet, Capulet, Lady Capulet and the nurse. In the previous scene Romeo and Juliet get married and the Montagues and the Capulets have a fight which leads to the deaths of Mercutio and Tybalt. Romeo is banished from Verona for murdering Tybalt because Tybalt has murdered Mercutio. Lady Capulet seems to support and comfort her daughter, but when Juliet argues and shouts she simply hands it over to Lord Capulet who will control Juliet. In the time of Shakespeare the men were in charge of the house and the children so the audience would have agreed to the play.Lady Capulet thinks that she can control Juliet, so she informs her of the marriage that has already been arranged. She seems very concerned about Juliet but she cannot control her herself and threatens Juliet â €Å"here comes your father. Tell him so yourself, and see how he will take it at your hands†. She means I will not say anything so see what your father has to say. In the previous scenes she was very quiet and innocent but in this scene she changes from being quiet into a very loud character which reveals her true nature.The Nurse is a very caring character and understands Juliet’s problems but in this scene she disagrees with Juliet as she advises her to marry Paris when she is aware that she has already been married to Romeo. This disheartens Juliet so much as she is the only person who she trusted. The Nurse says â€Å"I think the best thing to do is to marry the count† as if she is speaking to someone she doesn’t know. Juliet relies on her so much that she is shocked when she hears such a thing come out of the Nurse’s mouth. Juliet declares â€Å"from now on I will never tell what I feel in my heart†.She also doesn’t say this stra ight to her face as the Nurse would start avoiding her which would please her parents and lead to Juliet getting into more trouble. The Nurse tries to persuade Juliet of Paris’ superiority and believes â€Å"Romeo’s a dishclout to him†. The image of the dishcloth indicates that Romeo is not worthy of Juliet. This makes Juliet furious because it was originally the Nurse who reported positively about Romeo. In this scene the Nurse is ambivalent because she supports Juliet when Lord Capulet explodes with anger as Juliet refuses to marry Paris.In previous scenes the Nurse is very supportive and thinks of Juliet as her own daughter when she says â€Å"What, lamb! What, ladybird! †, but in this scene she changes from supporting Juliet to letting her down when she asks for her advice. Lord Capulet is a very strong character throughout the play but he does care about Juliet as he claims that he will not do anything against his daughter’s will but in this s cene he orders her to â€Å"go to church on Thursday or never look me in the face again.Don’t say anything. Don’t reply. Don’t talk back to me†. This quote would be very aggressive when said in the play as he is saying it with aggression and anger. Which shows that the old Capulet has gone. In this scene, generally, everyone shows their bad side as it is now getting serious about Juliet’s wedding. In this scene Capulet uses metaphors such as â€Å"when the sun sets, the air drizzles dew. But at the death of my brother’s son, it rains a down pour. What are you, girl? Some kind of fountain? he is comparing the downpour and the amount of tears that Juliet is producing and he is also trying to express that Juliet is not crying for her cousins death but crying for her husband Romeo. He also slams her on the floor while she begs on her knees and as he is not aware that Juliet is already married he repeatedly tells her to marry but the audience kn ows that if she marries she will go to hell as there is a sin if she marries again. This scene would have been very dramatic and sad as the audience would have felt sorry for her.By Capulet doing this creates a feeling of tension and pressure for Juliet as she is begging him. From the audience’s point of view, Juliet is very innocent but Capulet refers to her as a â€Å"disobedient wretch†. This shows the amount he cares he takes for his daughter. If this were to happen in today’s society maybe he would be prosecuted for child abuse. Later in the play Juliet pretends to agree to the marriage but nobody is aware of that. Friar Lawrence gives her a potion that she will have before the night of the wedding so that she will fall into a deep sleep and wake up after 12 hours.Act 3 scene 5 is one of the most dramatic scenes in the play. This scene leads to many misconceptions as the Friar Lawrence was supposed to inform Romeo of the plans but Romeo didn’t get th e message. But he got the news that Juliet had died. Act 3 scene 5 reveals most of the characters’ true natures. This scene is important as this is the scene that leads to the death of Romeo and Juliet and also it reveals the Nurses’ real character as she didn’t really understand the true love of Romeo and Juliet. All of the characters undergo a dramatic change in how they behave in this scene.

Crime-free Children Today Essay

Open a newspaper or switch on the radio for news and you will no doubt see a number of horrifying crimes reported there – murder, rape and robberies are no longer surprising or shocking news to the Indian citizens. But what can shock us is the fact that most, at least a third, of the crimes committed in a year are by youngsters below the age of 18. Juvenile delinquency is increasing rapidly. A large part of the world’s children are in India. Children are often perceived as the epitome of innocence and naivetà © by most people. But the phrase â€Å"child-like innocence† can no longer be used, because the adolescents are one of the most violent age categories in the world. There are many incidences of crimes committed by the adolescents these days. The number of juvenile court cases are increasing and the crimes become more horrifying by the minute. There are increasing evidences of road rages, crimes against women, violence in school etc. all committed by teenage rs. Parents and others involved in a child’s life are equally responsible for the child’s hostile behavior. The amount of violence in the adolescent’s day-to-day life plays a large role in this issue, too. The child’s guardians have to take time to understand this complex problem and try to solve it; but what most of the Indian parents do is say to themselves, â€Å"He/she will grow out of it,† and simply avoid the issue, hoping it is just a phase. But this ignorant way of treating the problem is the start of a life-long trouble that will not only affect the family, but also the society, because in most of the cases of aggressive juvenile violence, the adolescent grows to be a criminal, thus delaying the development and progress of the nation.  The family does not bother to think of what may be the cause of the child’s behavior. Violent mannerisms in children can include a wide range of behaviors: explosive temper tantrums, physical aggression, fighting, bullying, homicidal thoughts, use of weaponry, cruelty towards animals, destruction of property etc. Most of this is caused by the problematic upbringing of the child – parents who pamper and spoil their children or agree to the child’s tantrums are endangering the child’s future. The television and the media can also increase a child’s violent tendencies. A child tends to imitate what he observes and this is a huge problem in India, because Indian cinema often has its heroes resort to violence to bring down their opponents. This makes the child think that using assault and bloodshed to achieve one’s needs is fine. Video games lessen the child’s value for a human life, as most of them involve killing animated characters. Being a victim of sexual abuse, presence of firearms in the house and even head injuries during childhood can cause adolescent violence. Remember, violence always leads to violence. Now that most of the people and the Government of India are starting to recognize and address this issue, solutions have to be found and made accessible to the citizens. Parents have to look out for signs of intense anger, impulsiveness, irritability and cruelty in children and look for the reason. Feelings of revenge and vengeance should be discouraged; tell them what the Father of our Nation once said, â€Å"An eye for an eye makes the whole world blind.† Make it clear to them that violence does not solve anything. Only clearheaded thinking can lead to good results. The amount of violence that the child is exposed to through media has to be restricted, but the media can also help by raising awareness and to show the children the adverse affects of violence. Developing a reading habit is also highly helpful in curbing a child’s hostility. Family conflicts, problems in school, discrimination by other children etc. should be found out and solved. Parents should not hesitate to consult a psychiatrist if necessary. Making the adolescent part of the Indian population is necessary because only calm and responsible children can grow into stable, responsible, patriotic citizens in the future. We should remember that it is the youth that will shape our country’s future. Every child is bright in his or her own way and it is the duty of the adults to keep the light burning, for the next generation will fulfill the dreams of our great leaders and lead our  nation to its victorious destiny only if our society is united, strong and nonviolent. Teach the children to follow the Mahatma’s policy, the motto that toppled the British, the strongest invading force of the past century: nonviolence.

euro disney Euro Disney: The First 100 daysThe Walt Disney Company is the company that has several successful theme parks in the world, and every person around the world wants to go visit their theme parks. However, their overseas expansion in Paris, France was not very successful as their other theme parks in the United States and Japan. Their target market was focus on children and young adult all over the Europe, the problem was that their target range was too broad. Covering all over the Europe was ungovernable for Euro Disney because there are too many countries that have different languages and different cultures. Also, Europeans was not very open to American culture to accept as Japanese did because Japanese people had been entertained through Disney's cartoons and movies but European had not.People who visited Euro Disney was not satisfied with customer service in Euro Disney. The customers definitely expected the high quality of service as other Disney theme parks, but the European empl oyees did not provide the high-quality service as American employee did.Stunt action at Euro Disney, ParisAlso, the cultural difference between Americans and Europeans caused the dissatisfaction about the service. For instance, the Disney Company banned to drink alcoholic beverage in the Euro Disney Land as they did in other locations. Americans thought that the interests of children must be put first in an amusement park definitely, but Europeans did not agree with that position even though they are parents of children. Drinking wine was very ordinary thing for European people, and they did not even think drinking wine is bad for children. Thus, Disney's position about not drinking alcohol in the theme park sparked the French people's strong opposition. Finally, the company allowed drinking wine in the Euro Disney about a decade after the opening. This example shows...

Vascular Dementia Essays

Vascular Dementia Essays Vascular Dementia Paper Vascular Dementia Paper Background Vascular dementia is the second most common form of dementia after Alzheimer disease (AD). The condition is not a single disease; it is a group of syndromes relating to different vascular mechanisms. Vascular dementia is preventable; therefore, early detection and an accurate diagnosis are important. Patients who have had a stroke are at increased risk for vascular dementia. Recently, vascular lesions have been thought to play a role in AD. As early as 1899, arteriosclerosis and senile dementia were described as different syndromes. In 1969, Mayer-Gross et al described this syndrome and reported that hypertension is the cause in approximately 50% of patients. In 1974, Hachinski et al coined the term multi-infarct dementia. In 1985, Loeb used the broader term vascular dementia. Recently, Bowler and Hachinski introduced a new term, vascular cognitive impairment. Pathophysiology Many subtypes of vascular dementia have been described to date. The spectrum includes (1) mild vascular cognitive impairment, (2) multi-infarct dementia, (3) vascular dementia due to a strategic single infarct, (4) vascular dementia due to lacunar lesions, (5) vascular dementia due to hemorrhagic lesions, (6) Binswanger disease, (7) subcortical vascular dementia, and (8) mixed dementia (combination of AD and vascular dementia). Vascular dementia is sometimes further classified as cortical or subcortical dementia. Vascular disease produces either focal or diffuse effects on the brain and causes cognitive decline. Focal cerebrovascular disease occurs secondary to thrombotic or embolic vascular occlusions. Common areas of the brain associated with cognitive decline are the white matter of the cerebral hemispheres and the deep gray nuclei, especially the striatum and the thalamus. Hypertension is the major cause of diffuse disease, and in many patients, both focal and diffuse disease are observed together. The 3 most common mechanisms of vascular dementia are multiple cortical infarcts, a strategic single infarct, and small vessel disease. Mild vascular cognitive impairment can occur in elderly persons. It is associated with cognitive decline that is worse than expected for age and educational level, but the effects do not meet the criteria for dementia and are not associated with vascular risk factors or evidence of silent strokes or extensive white matter infarcts on CT scanning. These people have subjective and objective evidence of memory problems, but their daily functional living skills are within normal limits. In multi-infarct dementia, the combined effects of different infarcts produce cognitive decline by affecting the neural nets. In single-infarct dementia, different areas in the brain can be affected, which may result in significant impairment in cognition. This may be observed in cases of anterior cerebral artery infarct, parietal lobe infarcts, thalamic infarction, and singular gyrus infarction. Small vessel disease affects all the small vessels of the brain and produces 2 major syndromes, Binswanger disease and lacunar state. Small vessel disease results in arterial wall changes, expansion of the Virchow-Robin spaces, and perivascular parenchymal rarefaction and gliosis. Lacunar disease is due to small vessel occlusions and produces small cavitary lesions within the brain parenchyma secondary to occlusion of small penetrating arterial branches. These lacunae are found more typically in the internal capsule, deep gray nuclei, and white matter. Lacunar state is a condition in which numerous lacunae, which indicate widespread severe small vessel disease, are present. Binswanger disease (also known as subcortical leukoencephalopathy) is due to diffuse white matter disease. In Binswanger disease, vascular changes observed are fibrohyalinosis of the small arteries and fibrinoid necrosis of the larger vessels inside the brain. In cerebral amyloid angiopathy–associated vasculopathy, aneurysm formation and stenosis in the leptomeningeal and cortical vessels cause damage to the subcortical white matter. In hereditary cystatin-C amyloid angiopathy, patients have recurrent cerebral hemorrhages before age 40 years that can lead to dementia. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy is a rare autosomal dominant condition localized to chromosome arm 19q12 that affects small vessels supplying the deep white matter. Pathologically, multiple small infarcts are observed in the white matter, thalamus, basal ganglia, and pons. Other less common syndromes may lead to vascular dementia. Rare arteriopathies such as inflammatory arteriopathy (eg, polyarteritis nodosa, temporal arteritis) and noninflammatory arteriopathy (eg, moyamoya disease, fibromuscular dysplasia) can cause multiple infarcts and can lead to vascular dementia. Hypoperfusion due to large vessel or cardiac disease can affect the watershed areas of the brain and lead to vascular dementia. Leukoaraiosis  greater than  25%  is considered to be pathological. Subcortical vascular dementia  is a diffuse  small vessel disease with minimal or absent infarction with  homogenous pathological and clinical features. Mixed dementia is diagnosed when patients have evidence of Alzheimer dementia and cerebrovascular disease, either clinically or based on neuroimaging evidence of ischemic lesions. Growing evidence indicates that vascular dementia and Alzheimer dementia often coexist, especially in older patients with dementia. Autopsy studies have shown the association between AD and vascular lesions.3 Several recent studies also suggest that the risk of developing AD is increased when a patient is exposed to vascular risk factors such as hypertension, diabetes mellitus, peripheral arterial disease, and smoking, which usually are associated with cerebrovascular disease and vascular dementia. Recent evidence suggests that the vascular processes in both disorders may mutually induce each other. Apolipoprotein E may play a role in AD and vascular dementia. Apolipoprotein E-IV also increases the risk of dementia in stroke survivors and is a strong risk factor for the development of cerebral amyloid angiopathy in patients with AD. In elderly individuals, many cases of dementia may be caused by the cumulative effect of cerebrovascular and Alzheimer pathology. One-third of patients with vascular dementia are found to have significant Alzheimer disease pathology with cholinergic deficits in the nucleus basalis of Meynert. Vascular cognitive disorder (VCD) is a new term used to describe a particular constellation of cognitive and functional impairment spectrum that  ranges from vascular cognitive impairment (VCI) to  subcortical vascular dementia, poststroke dementia, and mixed dementia.2 Medical Care The mainstay of management of vascular dementia is the prevention of new strokes. This includes administering antiplatelet drugs and controlling major vascular risk factors. Aspirin has also been found to slow the progression of vascular dementia. Recent guidelines from the American Psychiatric Association provide both treatment principles and possible specific therapies. Drug treatment is primarily used to prevent further worsening of vascular dementia by treating the underlying disease such as hypertension, hyperlipidemia, and diabetes mellitus. Antiplatelet agents are indicated. Pentoxifylline and, to a more limited extent, ergoloid mesylates (Hydergine), may be useful for increasing cerebral blood flow. In the European Pentoxifylline Multi-Infarct Dementia Study, which is a double-blinded, placebo-controlled, multicenter study, treatment with pentoxifylline was found to be beneficial for patients with multi-infarct dementia. Significant improvement was observed in the scales used for assessing intellectual and cognitive function. Neuroprotective drugs such as nimodipine, propentofylline, and posatirelin are currently under study and may be useful for vascular dementia. Increasing evidence supports the involvement of the cholinergic system in vascular dementia, similar to that seen in Alzheimer dementia. However, no cholinesterase inhibitors have been approved to date for the treatment of vascular dementia, despite positive results in clinical trials with this medication. The general management of dementia includes appropriate referral to community services, judgment and decision-making regarding legal and ethical issues (eg, driving, competency, advance directives), and consideration of caregiver stress. Diet In the Rotterdam study, an increased risk of vascular dementia was associated with total fat intake, whereas fish consumption was inversely related to dementia. Low levels of folate, vitamin B-6, and vitamin B-12 are associated with increased homocysteine levels, a risk factor for stroke.

Calculating pH of a Strong Acid - Chemistry Problems

Calculating pH of a Strong Acid - Chemistry Problems A strong acid is one that completely dissociates into its ions in water. This makes calculating the hydrogen ion concentration, which is the basis of pH, easier than for weak acids. Heres an example of how to determine pH of a strong acid. pH Question What is the pH of a 0.025 M solution of hydrobromic acid (HBr)? Solution to the Problem Hydrobromic Acid or HBr, is a strong acid and will dissociate completely in water to H and Br-. For every mole of HBr, there will be 1 mole of H, so the concentration of H will be the same as the concentration of HBr. Therefore, [H] 0.025 M. pH is calculated by the formula pH - log [H] To solve the problem, enter the concentration of the hydrogen ion. pH - log (0.025)pH -(-1.602)pH 1.602 Answer The pH of a 0.025 M solution of Hydrobromic Acid is 1.602. One quick check to make sure your answer is reasonable is to verify the pH is closer to 1 than to 7 (certainly not higher than this.) Acids have a low pH value. Strong acids typically range in pH from 1 to 3.

Techniques used in Sustainable Agriculture Essay

Techniques used in Sustainable Agriculture - Essay Example The two chapters below discuss two techniques applicable in sustainable farming; Crop Rotation – it is the mechanism of growing crops in succession within the same field. Currently, it is subject to regard as the most powerful technique of sustaining agriculture, as it helps in avoiding most of the unintended consequences related to putting the same plants in the same soil year in year out. The technique is a key element of both permanent and effective solution to the pest problems. This is because many pasts seem to have preferences for the specific crops, and when there is continuous growth of the same crop, it will guarantee such pasts of the steady food supply, thus increasing on their populations. In this regard, rotation will help at reducing past pressure on all kinds of crops through breaking on the pest reproductive cycles. Through the same farming technique, farmers may plant crops like soybeans and other legumes, which have the capacity of replenishing plant nutrients, thus reducing on the need of utilizing chemical fertilizers. Cover Crops – It is a farming technique whereby a particular crop is planted for the intention of managing the soil. Through this farming technique, farmers have the opportunity of taking the advantage presented by the benefits of having plants growing in the soil at all times, as compared to the option of leaving the ground bare in-between cropping periods. The type of cover crops may include hairy vetch, clovers, or the oats. Plating of such crops helps farmers into achieving the basic goals of preventing soil erosion, suppressing the weeds, and enhancing the soil quality. Employing the use of this sustainable farming technique is worth the extra effort since it helps in reducing the needs for the various chemical inputs, such as herbicides, insecticides, and

Priority List - Essay Example In the list, Air force Plant 85 appears as number 1 with site identity number by EPA being OH1170090004, Allied Chemical & Ironton Coke appears as number 2 with site identity number by EPA being OH043730217 and Bowers Landfill listed as number 8 with site identity number by EPA being OHD980509616 (EPA, 2012; EPA, 2011; EPA, 2013). Hazardous chemicals listed in the inventory and associated with Allied Chemicals & Ironton Coke include benzene, ammonia, cyanide, naphthalene and Polynuclear Aromatics Hydrocarbons (PAHs) and phenolics (EPA, 2011). The ground water within the site contains all the listed chemicals, which are dangerous to human health. In the inventory list, Air Force Plant 85 characterizes with chemicals that include chlorinated solvents, trichloroethylene, PCBs and hydrocarbons. The site also suffers from contamination with dangerous metals like mercury, chromium and cadmium (EPA, 2012). The groundwater under the site has contaminations of the metals and chemicals, and unhealthy for human consumption. The inventory also features Bowels Landfill site as contaminated with contaminants such as barium, manganese, pesticides, volatile organic chemicals (VOCs), phthalates, lead, polychlorinated biphyenyls (PCBs) and arsenics, which have also infiltrated into the groundwater and making the water unsafe for human consumption (EPA, 2013). The chemicals and metallic substances within the sites infiltrate underground, contaminate and make the underground water unsafe for human consumption. Buying home within the sites can be the least decision considering that residing in the areas is tantamount to deliberate risking of one’s health and life especially if the areas rely on groundwater as primary source of water. However, if municipal authorities connect piped water into the areas surrounding the sites, then one can

God exists OR God doesn't exist OR We should believe in God OR We Essay

God exists OR God doesn't exist OR We should believe in God OR We shouldn't believe in God - Essay Example The planets, the stars and the suns move in certain direction that their gravitational systems do not collide with each other. In our own solar system, planets revolve around the sun in an orderly and predictable manner which makes us wonder, who created all these things to move in such controlled and orderly manner? If there is no God out there who created the universe and all the creatures that exist on it, then, who created all these things? The universe is so vast and almost impossible to comprehend and it revolves along logical paths that are exact and well defined. Many scientists and scholars suggest that the universe was created through some kind of random engineering design but if we take a close look at the solar system (Peacock, 1999), the planetary system and all of creation, there is nothing random in these things and everything has to be in their right places to achieve balance and harmony. If it was not God who created all the heavenly bodies and set the rules as to how they should move around and produce elements that sustain life, then, who created all these things? If the universe has been created by an accident of nature as some people would like to believe, such accident would have been of phenomenal magnitude that it created order in the universe. Besides, if we go with the idea that the universe and us who live in it, are created by accident of nature, then we are not as special as we are supposed to be. If we do not believe in God, then we do not consider ourselves as made in the image and likeness of God. By believing that we are created by accident is like denying our own divine beginning. On the other hand, by accepting the existence of God, we also accept our divine nature. In arguing against the existence of God, many scientists suggest that at the beginning of time, the chaotic first elements ordered themselves to form a complex system that we now call the universe (Singh,

CITY BUDGET ANALYSIS OF AVALON, CA - Essay Example 7.3 km of which (2.8 mi) is land and 0.9 km (0.3 mi) of the area (10.48%) is water (U.S. Census Bureau 2000). The process of preparing and presenting a budget for approval and adoption by the Council administration takes various steps. A proper estimate of the available resources with the estimated amounts and the purposes for which the funds are to be deployed effectively are the main considerations for the preparation of any budget. The formal budgetary process encompasses a structure involving the following essential components: The complexity of the budget review process depends on the size of the council for which the budget is being prepared. In some cases the budget responsibilities would be assigned to a chief executive officer for reviewing the requests and present them to the elected board for approval. When the unit is large there may be a separate budget office functioning within the council. In even larger City councils apart from the review by the budgetary office departmental budgets would be prepared and reviewed for appropriate provisions in respect of the individual departments. In the case of the City of Avalon, the City Manager and his office will be responsible for the preparation and presentation of the budget for the approval of the elected council members. Being a small town, there is no necessity to follow an elaborate budgetary process. The process broadly will follow the procedure outlined above and will be reviewed by the elected council members themselves for approval and adoption. 3.0 Strategic Goals and Key Performance Indicators: The administration of the City Councils has become the function of the elected representatives as well as the appointed officials who have to operate in unison with each other's ideas. If they start to function in tangential directions, it will be detrimental to the well being of the city dwellers, as no welfare measures can be undertaken without the concerted action of both these bodies. In order that the mission, vision and value of the city can be accomplished in all intent it is important to adopt certain strategic planning measures encompassing the performance of the city council or the county board as the case may be. Like in any other profit centered organization, the strategic planning helps setting the direction of the council and with the set directions, the elected street-level bureaucrats are motivated to perform at their best efficiency levels to organize the functions and activities of the Council in the direction of the welfare of the people of the City. Establishment of long-term objectives and goals are an essential pre-requisite of any strategic planning. Once the broader goals are established it becomes easier to break down them into smaller performance targets to be achieved by the appointed officials and the representatives. Just as in the case of private organizations strategic goals in respect of

Assignment 1 CB - Essay Example Being from an Arabic country and living away from my home country, I feel that there are some things that if I had a chance I would champion for change. Top on the list is the perception that the world and even some of the people in my current environment have on Muslims like me. Although I have knowledge and feelings, especially from some research, that the situation was worse years back I feel that I have a purpose to make things a little better. Throughout my years in school and now in college, my plans and goals have been those of helping others. These goals sometimes seem rather lofty and unrealistic even to me but with my desire to change, I always find success in my endeavors. I remember back in high school when one of my friends, a Jew, was in a problem with a teacher. I offered to help him even though he was wrong. I stood as his advocate and even got a nickname for it among my schoolmates. With my young age and a life ahead of me, I believe my culture will change the world. I believe all problems can be solved effectively and that all people can reach their full potential if given opportunities. The opportunities, according to what I have learnt in life means a proper environment and

Art and Function in a T-Shirt Essay Example for Free

Art and Function in a T-Shirt Essay Defining and evaluating artistic and aesthetic value has often been a problematic task. This is because aesthetic judgements are subjective and are influenced by prevailing cultural, economic, political, and social norms. Hence, the definition of art remains a contested domain between those who believe in â€Å"high art† and the advocates of artistic and cultural relativism. (Danto 35) The difficulty in ascribing aesthetic value to objects is evident in the fact that relativism, with its focus on the individual subjective experience, would render anything and everything as artforms since humans ultimately attach meanings to objects they possess. Changes in culture and socio-economic conditions also alter and influence the very standards by which the aesthetic value of art forms and other objects are judged. For instance, in judging a t-shirt with Bob Marley’s face printed on it on the front through the use of the silkscreen method, one easily dismisses it as a non-art when judged according to the traditional notions of fine art. This is because the t-shirt and the print on it do not express artistic creativity, which is a prerequisite for objects to be considered art forms. The t-shirt and the print, which can be replicated many times over by any one with knowledge on silk screen printing, do not possess relevant canonic properties of art such as unity, complexity, and intensity which could evoke intense human experiences and therefore, aesthetic appreciation (Goldman 185). The sight of the t-shirt does not stir up feelings of beauty nor does its fabric hold anything extraordinary for the senses. The print on the t-shirt does not convey a particular style to capture attention or cause pain or pleasure, at least not in the way that beholding Picasso’s paintings evoke wonder, mystery, and other psychological sentiments arising purely from the painter’s use of style, colors, and the imagination. Likewise, the t-shirt with the print on it was created not for the purpose of being admired as an art. As such, the t-shirt is not valuable in itself but gains value for its function to humans, contrary to traditional visual and other forms of art. Art forms are valued for their artistic worth or for their ability to command a definite blending of particular perceptual and sensory elements from the audience (Goldman 188). On the other hand, subjecting the t-shirt to evaluation based on the principles of aesthetic value leads to interesting results. The t-shirt with Bob Marley’s face printed on it clearly fulfills two aesthetic principles. First, the t-shirt becomes a medium for the image of Bob Marley, a cultural icon in reggae music and in the historical struggle of Jamaicans. In this case, the t-shirt with Bob Marley’s image transcends its status as an object worn by humans to cover themselves and becomes an expression of the values of reggae and Jamaican culture in a manner similar to cultural artifacts. Second, the t-shirt itself may be valued by an individual for the sentiments attached to the shirt. It could have been given as a gift for an occasion or has been worn to events associated with feelings of happiness which make the t-shirt valuable to the individual because of the memories of joyous times spent while wearing it. Thus, other people might consider the same t-shirt aesthetically valuable. Fenner observes that objects do not have intrinsic aesthetic value; rather it is the subjective experience of humans that create aesthetic value for objects, particularly the expectation of pleasure from an object (122). Those who appreciate and know Bob Marley may value his image on the t-shirt and subsequently feel pleasure or the elevation of other feelings associated with Bob Marley’s musical contribution and historical roots. As such, the t-shirt may be appreciated by people who share a cultural affinity with Jamaica or of the counterculture that Bob Marley represents. The value of Bob Marley’s silkscreened image extends to the t-shirt which carries it and reinforces the value of the shirt for its owner. The t-shirt, donned by the owner, can therefore be considered the medium for the expression of individuality and creativity of the wearer. Wearing Bob Marley may be a political or cultural statement for a particular culture, particularly as a representation of the struggle against apartheid or against conventional popular music and the culture it represents. Hence, the appreciation of Jamaican culture or reggae music becomes another definitive aspect of the aesthetic experience that may be separate from the experiences attached to the t-shirt as an object. Likewise, neither the fact that the t-shirt was not created for the sake of art nor its low economic worth prevents it from being categorized as an art form. Fenner notes that the presence of traditional aesthetic properties do not necessarily lead to an aesthetic experience or to the creation of an aesthetic value (121). Hence, the audience can view a pricey painting without feeling any connection with it which would make the painting worthless in terms of evoking a subjective experience of appreciation for creativity or imagination. On the other hand, the same audience may behold the image on a shirt and feel an instant connection, a feeling of intense emotions from memories or meanings attached to the object of attention. It is clear that the traditional definitions of art and the accompanying distinction and stratification between â€Å"high art† and â€Å"lowbrow art† has slowly been eroded with the rise of cultural relativism and postmodern theory. Doubtless, the rigid formality of art has come under attack even within various artists’ circles itself that ascribe to the fluidity and less structured styles of postmodern culture. Thus, even an ordinary t-shirt can now be considered an art form when, after critical analysis, it is able to fulfill the principles of aesthetic value. Works Cited: Fenner, David E.W.

Pearl Harbor :: essays research papers

PEARL HARBOR AMERICA ENTERS THE WAR   Ã‚  Ã‚  Ã‚  Ã‚  December 7, 1941, â€Å"A date that will live in infamy,† was the name that our President gave the worst military attack ever on United States soil, Pearl Harbor. It all started in May 1940, when Japan sent Kiichi Gunji to the newest Pacific Battle Ship Port. We chose to read this book because we both are interested in Pearl Harbor and the new movie about it.   Ã‚  Ã‚  Ã‚  Ã‚  A major incident in the book Pearl Harbor was how the Japanese got all of the information it needed to attack the United States. They came over by a cruse ship from Japan to Hawaii and went around Hawaii like tourists. Yoshikawa and Mikami was the main spy who went around the island in a taxi with the driver named Kotoshirodo. They spied from several spots but liked the pier at Pearl City the best. He liked it so much because he could see the Pearl Harbor and the naval air strips on Ford Island from there. He went every so often so he did not make anyone too suspicious and also made sure he never went in the same clothing each time he went. He sent all the information he gathered and sent it back to Japan to be looked over. These spies where a major part of the story and the way the book ended. Another major event in this story is when the author talked about Yamamoto’s Operation Hawaii and all the problems with them. In February 1941, Commander Minoru Genda was assigned to Yamamoto’s Operation Hawaii. His comment was the plan was difficult but not impossible; but he turned down a lot of Yamamoto’s idea. Some ideas he didn’t keep were: the plans would take off from carriers about 500 miles from Hawaii. They would not have enough gas to make the trip there and back to the carrier ships, so Yamamoto’s plans to fly towards the carriers until their gas ran out and ditch in the Pacific, was scrapped. Genda wrote up a new plan that had the attack starts at dawn and should be a total surprise. Carriers would refuel at sea at Midway Island, and the planes would drop torpedo, dive, and high-level bombing on the United States ship and planes.

Sigmund Freuds Representation of Three Tall Women Essay -- Freud Psyc

A Deeper Understanding of Three Tall Women According to Sigmund Freud, psychoanalysis is a â€Å"procedure for the investigation of mental processes which are almost inaccessible in any other way† (Fodor and Gaynor 147). It becomes a deeper contrast of a person’s mentality to consider the design of â€Å"interplay† within the â€Å"urging and checking forces† of the conscious and unconscious (Fodor and Gaynor 147). Freud’s representation of â€Å"Three Tall Women,† relate the characters by the â€Å"neuroses that sometimes result from the suppression of memories and desires too painful to deal with† (Freud, â€Å"The Dependent Relationship of the Ego). While not completely opposing religion as a factor in the conscious and unconscious, Freud does claim that the â€Å"Oedipus complex is at the root of religious feeling† (Palmer 113); so the idea of religion is not based on the desire of pleasing a God with the basis of good vs. bad, but instead, according to Freud, i t is the sexual desires that come from being attached to a father figure. As characters B and C are introduced first as outside acquaintances, then as stages of character A’s past, the play is transformed into what may be perceived as Freud’s theory to the relation of the conscious and the unconscious, but could also be noted as the change a person undergoes throughout their lifetime in which religion, or the desire to maintain morality, is checked by outside influences. The interpretation, backed by Carl Jung, argues that â€Å"religion need no longer be perceived as a conglomerate of guilt ridden repressions and ritualized obsessions, but as a natural and legitimate dimension of psychic activity† (Palmer 113). When Freud’s argument is counterbalanced, it can be found that the interpretation F... ...ud may be correct on some terms, but the true unconscious desires do not come from a sexual want, but more from the want of a moral individuality, and characters C and B epitomize such a notion and deep understanding that exists in character A, but is challenged with the influence of society and the struggles of growing older.

Biological Factors of Human Relationships

Biological factors are something that contributes hugely to the formation and maintenance of relationships- whether it is romantic, friendly or family related. Many researchers have conducted studies in which they have attempted to try and explain the link between biological factors and human relationships. I am going to specifically focus on Bowlby’s study on the role of hormones in bonding, Buss’ study on women jealousy and its relation to estrogen levels, Fishers study on the brain and its role in romantic relationships, and Marazziti who studied the effect of serotonin on love obsession.These studies will help me show the role that biological factors have in human relationships in both the development and maintenance of them. Serotonin. A neurotransmitter that may be involved in love, but is more commonly known as a chemical in the brain to change according to the moods of a person. A study conducted by Marazziti et al (1999) in Pisa (Italy) was to determine whether serotonin could perhaps explain the continuous focus on the beloved. The study mainly showed that the early stage of love really changes the way that people think.He used 60 participants; 20 who were in love, 20 who were OCD and 20 neutrals- who were not in love or OCD (controlled variable). He conducted the experiment by analyzing samples of blood from each of the participants. He found that the serotonin levels in the lovers were that of the same level as those participants who had OCD. This helps to show that there is a possible connection between the serotonin levels in the blood and the connection of romantic love.However some downfalls to this experiment could be the fact that Marazziti did not document or analyze and consider the serotonin activity in the specific brain regions may effect the validity and the reliability of the results from the study. This is because without having these factors being played into the study and research we are unsure of the exact role that se rotonin has in romantic love. Hence, the influence of this biological factor is not soundly connected with romantic relationships and has no definite tie to show how it affects or doesn’t affect it.The development of a relationship from the first and early stages of love to the more developed stages, couples tend to move from the passionate love to the more intimate relationship of relaxation, dependency, and security which all play into attachment. In 1969 Bowlby suggested, â€Å"Humans have an innate attachment system which consists of specific behaviours and psychological responses called attachment behaviours. † For his experiment it mainly was conducted for research on mother child relationships however many believe that the results are relatable to both mother child and romantic relationships.According to more modern research, it has been shown that both oxytocin- a powerful hormone which is released in men and women during touching and sex which helps to deepen and intensify the feelings of the select attachment- and vasopressin- a hormone released also during sex- help in increasing the bond that is between two lovers. Through this it helps the couples to feel closer and more bonded. One of the main criticisms of this experiment was the complexity of the researched relationships and how since they didn’t consider other factors that might affect the results, therefore resulting in the possibility that it could be unreliable.However if looking at just this one aspect, this biological factor can be considered to have an influence on human relationships both mother child and romantic, but it is unknown the influence when other factors are in play as well. In 1996, Buss suggested that jealousy may be something that is biologically based, and found that women’s patterns of jealousy vary throughout their menstrual cycle. So when oestrogen levels are low, women tend to be more sexually jealous where as when the oestrogen levels are relatively high women tend to be more emotionally jealous.This helped to set the base of his argument that â€Å"human sexual behaviour is grounded in the need to optimize the potential for reproduction, with the goal of the best genetic combination possible for the offspring, as well as maximizing parental care after a birth. † When he did his study in 1993 he found that women and men in regions of the world with high levels of pathogen stress rated the importance of physical attractiveness. For this study there was a huge amount of gender bias as he tends to favor men and only criticizes women†¦ This gives an uneven weighting and unreliable results from the research.Also he made generalizations that cant be made as different people have different personalities. Due to these criticisms, there can be hints at possibilities on his theories of this biological factors affect on human relationships however it is not something that has been proven. Finally, Fishers research i n 2001was a conducted study using FMRI (functioning magnetic resonance imaging) to analyze and examine the impact of the brain on romantic love. He took a large sample of young couples to test in this experiment.He took each person individually into the scanner and showed him or her a picture of their beloved and of an acquaintance in 6-second intervals. Throughout this process, Fisher got results that showed the brain in love. This is because the brain showed the â€Å"reward† system when the picture of their loved one came up however when the neutral or controlled picture showed, there was no activity. Interestingly, the more passionate people were- in accordance to the questionnaire they filled out of the â€Å"Passionate Love Scale† before the test- the more active the brains reward system was as well.All in all this shows that yes this biological factor does play a role in the overall outlook of human relationships. Overall, we can see that throughout the vast var iety of different studies done by a variety of different psychologists, there are quite a few things that a lot of them did not consider. Through this we can see that yes there are a lot of things that could play a role in the human relationships but due to the criticisms and downfalls of the studies we are yet to discover how much of a role they do actually play.

Formal Outline Essay

INTRODUCTION Attention material: The world stopped getting warmer almost 16 years ago, according to new data released last week. The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures. This means that the plateau or pause in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years. Credibility material: The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we’ve already set into motion? While we struggle to figure it all out, the face of the Earth, as we know it—coasts, forests, farms, and snowcapped mountains—hangs in the balance. Thesis statement: Today I want to share what I†™ve learned about global warming and it’s causes. Preview: We need to consider causes, effects and dangers of global warming. (Transition: Let’s begin by understanding more about global warming.) BODY I. The Earth is warming and human activity is the primary cause. A. U.S. scientists said in the media January 19, 2012, about the influence of mankind on the state of global warming has increased from 18% to 51%. B. The primary way humans cause global warming is by burning fossil fuels. 1. When we drive or fly. 2. When we eat meat and Exotic Foods. 3. When we use electricity. 4. When You Move Into A New Development. (Transition: Now, from this it becomes clear why humans are the main cause of global warming, let’s examine its major effects) II. Global Warming effect information. A. The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. B. Some impacts from increasing temperatures are already happening. 1. Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. 2. Researcher Bill Fraser has tracked the decline of the Adà ©lie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years. 3. Sea level rise became faster over the last century. 4. Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas. 5. Precipitation (rain and snowfall) has increased across the globe, on average. 6. Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees. C. Other effects could happen later this century, if warming continues. 1. Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters). 2. Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years. (Transition: So now, we know about global warming effects, let’s see our future†¦and how we can fix it!?) III. Predicted Effects and Impacts of Global Warming. A. Future effects about global warming. 1. Increased spread of infectious diseases: â€Å"an increase in the number of people exposed to vector borne diseases (e.g. cholera) and an increase in heat stress mortality.† 2. Degraded water quality: â€Å"Projected climate change will tend to degrade water quality through higher water temperatures and increased pollutant load from runoff and overflows of waste facilities.† 3. More frequent and more intense heat waves, droughts, and tropical cyclones. B. Some basic predictions of global warming. 1. Global mean temperature should increase by between 1.4 and 5.8 C (2.5 to 10 F). 2. The sea level should rise by between 9 and 88 cm (3.5†³ to 35†³). (Transition: Finally, I want to tell you about the solution of this huge problem.) IV. Solutions to Global Warming. A. There is no single solution to global warming. 1. Boosting energy efficiency. 2. Greening transportation. 3. Revving up renewables 4. Phasing out fossil fuel electricityManaging forests and agriculture 5.Exploring nuclear 6.Developing and deploying new low-carbon and zero-carbon technologies. 7. Ensuring sustainable development CONCLUSION Summary statement: Some impacts—such as record high temperatures, melting glaciers, and severe flooding and droughts—are already becoming increasingly common across the country and around the world. However, there is much we can do to protect the health and economic well-being of current and future generations from the consequences of the heat-trapping emissions caused when we burn coal, oil, and gas to generate electricity, drive our cars, and fuel our businesses. Concluding remarks: Since 1880 the world has warmed by 0.75 degrees Celsius.

Critical Response Paper to Mike Rose’s I Just Wanna Be Average Essay

In his essay â€Å"I Just Wanna Be Average,† Mike Rose details his school life in South L. A. Now a professor of Education and Information Studies at UCLA, Rose moves through secondary school at Our Lady of Mercy on the Voc. Ed. Track, revealing why the standardized versions of this â€Å"educational system† betray the core values behind liberal, humanistic education as we understand it. As Rose wants to stress the value of all individuals, the discrepancies between their actual intellectual capacities and how the system classified and treated them, he paints his fellow students in Vocational Education in great detail. His title comes from Ken Harvey, who, among the many colorful characters and lively Americans Rose met, dropped the defining one-liner of his entire Voc. Ed. Experience: We were talking about the parable of the talents, about achievement, working hard, doing the best you can do, blah-blah-blah, when the teacher called on the restive Ken Harvey for an opinion. Ken thought about it, but just for a second, and said (with studied, minimal affect), â€Å"I just wanna be average. † That woke me up. Average? Who wants to be average? At the time, I thought Ken’s assertion was stupid, and I wrote him off. But his sentence has stayed with me all these years, and I think I am finally coming to understand it (Rereading America, 186). Rose goes on to attempt to clarify his understanding of this one-liner and how it fits in America’s education system. He reveals how Ken Harvey was trying to protect himself, â€Å"by taking on with a vengeance the identity implied in the vocational track† (187). Rose himself was lucky, switching to College Prep and meeting a belated beatnik intellectual-turned-educator named Jack MacFarland, and a hard-nosed science teacher named Brother Clint. These characters brought a college preparatory curriculum to a place and students who had never seen it before. And Rose reveals how classism and racism most often prevent that from happening, wasting entire American populations in entire communities deliberately, all while demanding higher â€Å"standards† and â€Å"accountability,† when the real efforts are never made, save in name and sprinkled across the land as media headlines. Rose’s essay reveals the multitude of challenges that students face, from struggles with family at ages that leave them ill-prepared to handle the emotional fall-out, to struggles with the emergence into a broader American world, to engaging in their own developing sexuality and its uncertain role in the context of their lives: work, and dreams, and the sense of possibilities of what life can or cannot be. I think Rose does a great job bringing this school in South Los Angeles to life. I can hear Ken Harvey, and see Jack MacFarland. When we hear him diagnose Ken’s problem, and his response to it, he’s very believable. He describes how kids get assigned to Voc. Ed. , being defined as â€Å"slow. † And he reveals the results: â€Å"You’ll have to shut down, have to reject intellectual stimuli or diffuse them with sarcasm, have to cultivate stupidity. † I wonder though, what he thinks the answers are. Is it smaller classes, or teachers that care? Obviously, Brother Clint and Jack MacFarland are teachers that care, and work hard to connect with every student. But not all teachers are like that, right?

Mending Wall of robert frost Essay Example | Topics and Well Written Essays - 1000 words

Mending Wall of robert frost - Essay Example We wonder from before we even begin to read the poem, what could be a mending wall? Does it talk of a wall that mends itself? Frost's "wall" is a metaphoric representation of something much more substantial than just a lifeless pile of stones. This wall can be associated with many things. It may represent a barrier, a boundary between two unlike existence. It may speak of segregation, of differentiation, of the negative connotation of being different from one another. It is something that keeps one thing from one labyrinth to reach another. This mystic feel embedded on the title arouses interest from the unknowing reader. Since there is so much a wall implies to be, the interest to know more about what this wall could possibly pertain to leads the reader to dig further and unfold each word that follows. Reading the first few lines of the poem, the reader finds out how "something" dislikes the erection of the wall. It is as if this "something" purposely deconstructs the wall to the po int that two individuals may pass through it side by side. On the 6th line of the poem "I have come after them and made repair", Frost uses "I", him speaking on the first person's point of view. His use of "I" implies not only of him as the writer telling a story but it symbolizes anyone as an individual. It is his way of giving the reader that sense of belongingness to the poem that creates the connection of the reader to the piece. This connection makes it much easier for the reader to relate to what the writer is trying to relay. Frost's imagist-like approach in the usage of simple and precise imagery is with great depth in meaning. The 12th line, "I let my neighbor know beyond the hill", tells the reader that the wall is dividing two neighbors. They meet occasionally to reconstruct the wall again; stone by stone they pile them back to its original form. This speaks of two different people or it may speak of a larger number of dissimilar groups of individuals constantly building walls against each other to keep one another from getting across. In this world, we people build barriers due to our fear of being engulfed by the other. Sometimes we rebuild the walls our forefathers have placed without even wondering what the wall is really for, just like the neighbor in the poem. As the poem progresses, the first person "I" started to question what the walls are for. On the 23rd to the 26th line, he stated: There where it is we do not need the wall: He is all pine and I am apple orchard. My apple trees will never get across. And eat the cones under his pines, I tell him. On the 27th line, the neighbor answered, 'Good fences make good neighbors'. It becomes all the more puzzling to "I". What is there to keep from each other? There are no cows to wall in or wall out. The poem concludes that even if there is this "something" that persistently destroys the wall, the neighbor continues to stand up for "his father's saying". The "wall" symbolizes the unwillingness of t he people to accept each other's differences as stated in the last lines of the poem. For the analysis of such a literary piece, the theme is certainly an important element. The theme plays an important role for the analysis of a poem with such a depth in meaning. Frost uses a similar style used by imagist. The use of free verse and precise imagery with the use of simple and direct words that can easily be associated to the scene or picture the writer tries to portray. The 40th and 41st lines of the poe

Louis V. Gerstner Jr Research Paper Example | Topics and Well Written Essays - 1000 words

Louis V. Gerstner Jr - Research Paper Example Question is: Is leadership is different from management? Since the answer is yes, was Gerstner an effective leader? In his book â€Å" Elephants Can’t Dance â€Å", Gerstner during his first day at IBM stated the following â€Å" I’d like to say to all of you is that the last thing IBM needs right now is a vision†¦what IBM needs right now is a series of very tough-minded, market driven, highly effective strategies for each of its businesses† (Gerstner, 2002, p.68). After his speech, he began putting his hands on the dirty job which included letting go of no less than thousands of employees. He was serious about the business of keeping IBM afloat and popularity of his decisions was the least of his concerns. IBM learned a painful lesson in management and leadership from Gertsner but it was able to go back to its feet and survive tougher circumstances like the recession today. A study published in the journal Industrial Management identified practical qualities of effective leaders. Gerstner has at least two practical qualities that made him an effective leader, namely: â€Å"lead by example and read situations and people well â€Å"( qtd. from Enterprenuer.com). Gerstner employed these three practical qualities when he read IBM’s situation clearly because he knew what has to be done despite the surmounting odds way back then. This is not definitely pure luck as this quality was honed by years of experience at a previous company – American Express. It is possible that good instincts and lessons learned from mistakes developed Gertner’s keen observation of situations and people in a business environment. When he was hired as consultant for the fledgling Sony, Gerstner again read the situation as he said†   "The cultural issues, as I found at IBM, are the most fundamental, the most difficult."( Gunther, cnnmoney ,2006) In shor t, he mentored Stringer through

The British Empiricists and Kant's Ethics Essay Example | Topics and Well Written Essays - 500 words

The British Empiricists and Kant's Ethics - Essay Example First, because of the theory of conatus, painful things happen to us because of external and not internal causes. And second, passive emotional states or passions, arise only from inadequate ideas – anger, fear, hatred, occur because of ignorance or incomplete understanding of their external causes. Therefore, in so far as we have an adequate idea of our emotions and their causes, we will not be subject to passions. The British empiricists all believe that knowledge is derived from experience alone. This aspect of arriving at knowledge seems quite interesting from the point of view of Locke, Berkley, and Hume. For Locke, our mind is a blank and clean slate, which he calls â€Å"tabula rasa.† Thus, all ideas and knowledge can only come to us and are founded upon experience alone. On the other hand, for Berkeley, all that we ever know are the qualities of an object that our faculty of vision is capable of sensing. Hence, it implies that any given object is the summation of its perceived qualities. Lastly, Hume sets out to achieve the limits of our knowledge. Herein, as far as knowledge is concerned, we are limited to our impressions and their corresponding ideas, which manifest in constant conjunction through experience. We have no way of knowing what causes them. For Hume, if an idea has no corresponding impression, then it is meaningless, that is, it does not exist. Kant’s ethics distinguishes between â€Å"acting in accordance with duty† and â€Å"acting for the sake of duty.† The latter are actions that have moral worth, while the former has no moral worth. Moreover, Kant explains another way of determining whether an action is morally good or not. This is presented in The Categorical Imperative. This principle states that before I will a certain mode of conduct, I should see to it that my subjective course of action could be universalized as a moral legislation. If my desired act involves certain contradictions, then my act cannot qualify as  a moral law and must be rejected. However, if it is devoid of contradictions then, it can be morally acceptable.  Ã‚  

Clinical use of Forgiveness Research Paper Example | Topics and Well Written Essays - 2000 words

Clinical use of Forgiveness - Research Paper Example motes healthy interpersonal relations as it makes it easier people to get along with each other in good spirit and with no grudges held against one another (Braaten and Darling, 1962). It is based on such studies that the current research paper is being conducted as a means of using quantitative strategies and data collection approaches to test the validity of this position held in literature. But more importantly, the researcher holds the position that before the benefits of forgiveness can be experienced there must first be a means by which forgiveness can take place. In the light of this, the study also focuses on selected factors that can influence the ability of people to forgive each other. On the whole, the study comes as a two-way approach which first focuses on factors that bring about forgiveness and the outcome of forgiveness. To do this, a various sample sizes made up of people with some level of religious background and those with no religious backgrounds were set. The reason for doing this was to measure religiosity and its impact on affecting a person to be forgiving. There were different outcomes that were measured in the various sample groups. These included behavior, affect and cognition. Later in the study, the findings of the intervention on its ability to lead to forgives and the outcome of such interventions are presented and discussed. It is widely known that religiosity and forgiveness have a positive impact on an individual’s psychological, emotional, and physical wellbeing. Numerous studies have attested to the fact that religiosity and forgiveness moderate the growth of suicidal ideation, especially for adolescents. However, even though these correlations are well-documented further research is still needed in this area because of some major gaps in the literature, like the use of cross-cultural methods in examining the correlation between forgiveness and suicidal ideation. Therefore, this study formulated three hypotheses,

Political Act Essay Example | Topics and Well Written Essays - 1000 words

Political Act - Essay Example He resigned the Yugoslav presidency amid demonstrations, following the disputed presidential election of September 24, 2000. (wikipedia.com). He surrendered to the JSO (an elite group of police in Serbia), to avoid forced arrest in April 1, 2001. This put in compliance with an American deadline. The warrant had previously been made on suspicion of corruption, abuse of power, and embezzlement. The charges were domestic. The legitimacy of the arrest was not proven since Milosevic surrender; however putting Milosevic in jail is not legal. The investigation does not have a hard evidence to convict the former president. The Serbian Prime Minister Milosevic act during the war convicted him for committing war crimes. During the Yugoslav war in 1990 and Kosovo war in 1999 he conducted his own defense at the International Criminal Tribunal for the former Yugoslavia, where he stood accused of crimes against humanity, violating the laws or customs of war, grave breaches of the Geneva Conventions and genocide. The decision of the court of not giving him the proper medical treatment is legitimate in the sense that he is convicted of a crime, but the said action is illegal since every person is entitled to have a proper treatment. His trial ended without verdict because he died during the proceedings. He suffered from heart ailments and high blood pressure. In the case of President Milosevic he had made a legitimate act during the war since he is the president; however he violated the laws of war and the Geneva Conventions. The political acts performed by Milosevic are a good example of legitimate act but legal. There are also cases wherein political act is legitimate but it does not necessarily need to be legal. In the case of the American and the British decision to attacked Iraq and engaged into war is legitimate. In the inquiry of people in the website of Noam Chompsky one question goes like this: "Do you think that, after the unjustified and unjustifiable war against Iraq, the world will lose the meaning of its existence, like in the field of language, when we lose the grammatical rules Will we automatically lose the reference of the meaning of sentences, and consequently the meaning of the world around us" Noam answer this question by citing one statement done by a follower of the Iraq war, Michael Glennon, who argues that we should recognize that international law and international institutions are what he calls hot air. They have proven their inapplicability by the fact that the United States disregards them, and he says it is right to disregard them, and the United States must maintain the right to use force as it chooses, independent of these institutions, which we simply have to dismiss and disregard. The act of Americans and British against Iraq has gain criticism throughout the world. But the said act is legitimate. The legality of attacking someone is not being followed especially during the time of war or the need to have a war. In the case of the American President he needs to make decisions depending on the

A comparison of text and a production of Shakespeares Macbeth Essay Example for Free

A comparison of text and a production of Shakespeares Macbeth Essay From page to stage- A comparison of text and a production of Shakespeares Macbeth. I have decided to aim my coursework at the scene where Banquos ghost appears to Macbeth. I am basing my coursework around the reactions of Lady Macbeth and Macbeth, and also the way in which Banquo is portrayed to us in Shakespeares play and the performance, which we attended, by the Long Overdue Theatre Company. I am comparing each of these characters from the performance with the way that they are portrayed in the written version. In the TLOTC performance; we receive a calm atmosphere at the time of the banquet, however in the written version more mysterious version is revealed to us. In the production version I dont feel we were given a very clear image of how Macbeth changed throughout the scene. The text initially portrays an image of how horrified Macbeth is when he sees Banquo sitting at the table. When reading the play we can visualise whats happening throughout the scene. We can visualise how Macbeth talks to Banquo as though he is fully human and is really there. We see this by the way Macbeth speaks to Banquo, Never shake thy gory locks at me. It is in this way that we can tell clearly whats happening in this scene. The TLOTC portrays this to us well, I feel that they gave us the clear view of Macbeths feelings towards the ghost. I feel that this helped us to realise the fear that Macbeth felt. They showed Macbeths actions clearly, he was very shaken and scared, I feel that the tone of voice he used was very effective. I feel that we learn more about Macbeths astonishment and disbelief in the TLOTC performance than in the text. Macbeth asks Which of you have done this? This shows us that Macbeth is in shock at what he is seeing before him. In the performance we are able to see the facial expressions, I feel that this helps us to get a clearer view at what Macbeth is feeling. Whereas in the written version we can only try and visualise what Macbeth is feeling. The tone of voice use helps us to realise the tension which Macbeth feels. Each time Banquo entered the room Macbeths tone of voice changed: it became shaken and very loud. I think that Ben Shockley portrayed this very well in the performance. Macbeth tries to tell the others what he sees before him. He says to them If I stand here I saw him. In the written version we cant tell what type of voice is used so less emphasis is put on Macbeths words. The supernatural elements were portrayed to us more clearly in the performance. In the written version Shakespeare gives very few stage directions. In the LOTC production I felt that the sound effects that were used each time Banquos ghost appeared were very effective, in the way in which we are able to tell when Banquos ghost was appearing. We get none of this build up of tension from the written version. I feel, however, that the written version is much fuller than that of the performance as the impact of Shakespeares language was more obvious. This was particularly at the beginning of the scene, where Lady Macbeth seems to have a very calm, patient attitude towards Macbeth. Lady Macbeth says to the others in a calm voice Sit, worthy friends, my Lord is often thus. We can see Lady Macbeths attitude change towards Macbeth in both the performance and the written version. When she hears Macbeth speak to the ghost but she doesnt know who her husband is talking to. Lady Macbeth tries to be strong and reassure everyone that Macbeths behaviour should not alarm them, when she says to them: My lord is often thus, and hath been from his youth. As Macbeth begins again to talk to Banquo Lady Macbeths attitude changes again, she begins to panic a lot more. I feel that the way she was panicking partly was giving away their innocence. Lady Macbeths panic is conveyed on stage when she says Pray you speak not, he grows worse and worse, questions enrage him. At once, good night. In the LOTC performance and in the written version Lady Macbeth is shown as the stronger person between her and Macbeth. Lady Macbeth begins to get so antagonised that she begins threatening Macbeths right to call himself a man: she says What, quite unmanned in folly? I feel that the performance gives a better view on Lady Macbeths strong will to keep her and Macbeth from looking guilty. Lady Macbeth tells Macbeth not to worry as she is afraid that all his worrying will give away their innocence. I feel that the blood, which appeared from Banquos mouth and nose, helped the audience to visualise Banquos presence as a ghost, of a murder man, intent on making his killer suffer.

Spacetime Structure Implications from Quantum Mechanics

Spacetime Structure Implications from Quantum Mechanics Spacetime Structure Implications from Quantum Mechanics and Relativity Abstract Some idea proposed in the recent Penroses Conformal Cyclic Cosmology (CCC) is discussed in this paper. In CCC it is argued that the concept of time looses its meaning in a Universe filled solely with zero rest-mass particles (i.e. photons and gravitons). This particular idea is discussed, because at least conceptually it can have some implication on our understanding of spacetime and a role of rest-mass. Relativity was a great revolution in our understanding of space and time, sometimes leading to paradoxes. Quantum Mechanics introduced quanta of energy. It occurs that the existence of the minimum quanta of energy can has a strong implication on the spacetime structure. abstract should include at the max. 250 words. The abstract should give readers concise and correct information about the material of the article. It indicates what methodology you have used for your results and how you are concluding these results. The abstract should be restricted into a single paragraph with Times New Roman with Font Size 10, with proper justification. Keywords: quantum mechanics; general relativity; conformal cyclic cosmology Introduction Einsteins Relativity theory has been experimentally verified very thoroughly and also Quantum Mechanics predictions are experimentally very well checked. The philosophical or physical interpretation of mathematical equations of Relativity is commonly accepted. However Quantum Mechanics is a very good working operating tool, whereas the interpretation differs widely amongst physicist and philosophers (outlook of various interpretations can be found e.g. in [2]). Basing on the recent Penroses cosmological proposal [9] it seems that some implications to our understanding of spacetime can be derived from principles and as consequences of Relativity and Plancks law. It can also lead to a specific interpretation of a wave function in Quantum Physics. The Penroses selected idea will be presented at first. Then some considerations influenced by this idea will be discussed. Problems with time measurement In [9] Penrose states that in a spacetime filled solely by photons and gravitons no clock can be built (Only the fact that rest-mass is zero is important. Therefore in the rest of this paper only photons will be discussed. Anywhere in the text when a photon is discussed it is important that it is a particle with zero rest-mass.). In order to have any clock a massive particle is needed. A stable massive particle â€Å"ticks† with the specific frequency (It can be derived by combining Plancks formula and Einsteins formula . Detailed discussion is in [9].). (1) . So when there is no massive particles a spacetime looses its metric structure and only the conformal structure remains. On the other hand the black hole evaporation process (known as Hawking radiation) [5] may lead the Universe to such a state in a very long time. Simply speaking if the Universe will be expanding (and therefore cooling) then after some time the background will be cooler than all black holes. Of course the infinite expansion is assumed. There are however some objections, because there may be some matter left, not collapsed to black holes. E.g. some lonely massive particles can resist. Penrose discuses both possibilities: some highly hypothetical process of loosing mass in a very long period and implications of an event horizon. It is not a scope of this paper to discus it more thoroughly. Only to state that a spacetime filled only with zero restmass particles is physically interesting, reasonable and possible. Penrose argument that in such a spacetime no time measurement can be done (and only conformal structure remains) seems true [3, 11]. Briefly â€Å"one can dispense with the geodesics neither of test particles nor of light rays in measurement process† [6]. More discussion on this topic can be found e.g. in [10]. In this paper it is assumed that Penroses proposal is true and if spacetime is filled with zero rest-mass particles or massive particles which cannot influence each other due to event horizon the n time cannot be measured in such a spacetime. Possible consequences of this statement will be discussed. Proper time of a photon, the Observability Principle and tiling a spacetime Let us consider a spacetime filled only with zero rest-mass particles. From Special Relativity it is known that any of such a particle â€Å"feels† no proper time. For example no time passes for a photon between its emission from the Sun and its absorbing on the Earth. Time passes e.g. for people on the Earth, but no time passes for a photon. Sticking to the Observability Principle, which means that anything which cannot be observed does also not exist [7, 8], one can say that for a photon both events take place at the same time (Because time difference between leaving the Sun and coming on the Earth, such as for the people on the Earth, does not exist for a photon and is not observed by a photon.). It means that no time passes in the Universe filled only by zero rest-mass particles just as Penrose concluded in [9]. For the sake of clarity such a Universe will be called a Penroses Universe further in this paper. Fig. 1: To distinguish between different configurations time is needed. In case of no time (inability to measure time) one can say that all possible configurations happen at the same time. Or simply each particle is at the same time in all possible places. It seems important to present some consideration here (which was not stated by Penrose). From the above paragraph it can be concluded that different configurations can be realised in the same time. Here a time is understood as an internal property of a Penroses Universe. The meaning of adjective internal will be clarified throughout the rest of this paper. Of course we are used to measure time for example by comparing configurations of objects (e.g. distance proportions between parts of them, etc.). When we see an egg on a table and next we see smashed egg on the same table we guess that a time has passed. In sake of clarity in a Universe filled with photons solely we should distinct between configurations (able to happen at the same internal time) and events (which happen one after another due to the order of the arrow of time). In a Penroses Universe configurations are possible, but events are excluded by the definitions. So in a Penroses Universe each possible configuration takes place in the same (internal) time. Equivalently they just take place simultaneously. (If there is no time it can be said that everything happens at the same time.) If one considers all possible configurations in a Penroses Universe, one can equivalently say that each zero restmass particle is everywhere at the same (internal) time (Let us notice that we may omit internal because if it is assumed that nothing exists except a particular Penroses Universe then any other reference for some other â€Å"time† cannot exist.). Of course the fact that a photon â€Å"feels† no time when passing from A to B i.e. that it has zero proper time does not imply that it is therefore everywhere in spacetime and, in particular, it does not mean that it is â€Å"simultaneously† on all possible paths between A and B. Indeed, in relativity theory, light moves on well-defined null geodesics. What I am trying to emhasise is that without massive particles it is impossible to discriminate these geodesics [3] and therefore (actually this is the crucial step) following the Observability Principle we identify all situations that are undistinguishable. It may be concluded that this is somehow similar to rather commonly agreed thought that the reality emerges only in relation to the results of measurements. Fig. 2: In A there is no massive particle. In B there are some. Time exists internally in B. A is a tiny Penroses Universe without time (as far as no interaction with B happens). A (global) time for which we can treat A as Penroses Universe is measured in B, because in A no time exists. It means that on A+B there is a time. Such a picture is not valid in our Universe because efficient clocks exist in it. The apparent contradiction occurs only because we imagine a Penroses Universe from the external point of view (experiencing the flow of the time). If we imagine that nothing exists except a Penroses Universe we would not have to use internal to describe time. Simply no device to measure time flow would exist. Now let us think about a spacetime as a manifold (as in General Relativity). One living in the spacetime approximates the global structure of the whole manifold by observing his neighbourhood. However locally there is no â€Å"absolute time† as Relativity states. Consider now a small tiny part of the Universe (an open subset in the manifold). The Universe is filled by both zero and non zero rest-mass particles (as our Universe we live in). But locally we can find small parts of it which are filled solely by photons. We can treat each such a part as a Penroses Universe as far as no interaction with any massive particle takes place. It is due to previous considerations. We can say that no time passes inside such a part as far as no event takes place. It is understood that events take place in the global Universe. And by the event we mean here some act of interaction between a part being a Penroses Universe and a part of the global Universe possessing at least one non zero rest-m ass particle. Then these two parts can be treated as one part (being then not a Penroses Universe). In other words let us find in our Universe as much as possible very small Penroses photon filled local Universes. These small Universes differ from Penroses one big Universe by the fact that they can be treated as such only as far as they do not interact with some massive part. The idea of tiling the spacetime manifold is sketched on pictures. Fig. 3: An interaction happened from part B to part A. A is no longer a Penroses Universe. Fig. 4: Such a timeless Universe cannot be divided into a massive parts and Penroses Universe parts. No matter how we would tile this Universe each component has no time. In a Penroses Universe it is unclear how the different configurations (spacetime paths) are to be defined. Indeed, just as there is no time measure, so there is no spatial measure (with which one can distinguish, for instance the distance between points on two different paths). Therefore due to the Observability Principle particles in such a universe are as if they were everywhere at the same time. What is needed to talk about any time order is an interaction with some massive particles. Only then e.g. before and after are sensible notions. Discussion on the Double Slit Experiment In the famous doubleslit experiment a photon seems to pass through both slits at the same time. Therefore a wave function has been introduced, because a particle behave as if it were a wave. However if one tries to localise through which slit a particle actually passes, interference image is erased and a particle behaves as a corpuscle. Therefore one says about corpuscular-wave dualism. But due to considerations in previous paragraph one should also be able to say that a photon really passes through both slits (because no time passes for a photon, so two event take place for a photon at the same time). And what is called a collapse of a wave function is just a choosing of a particular path out of all possible. Such a measurement is however possible only if non zero rest-mass is involved. It is known that as a particle becomes more massive quantum properties are less clear and lighter particles behaves more like a waves (photons, electrons). The ability to measure time interval can al so be seen from Eq. (1). In such an interpretation a wave function is not an abstract existence in observer mind. It is a physical being. But as such should somehow depend not only on a particle but also on a spacetime in which is considered. Summarising Relativity Einstein once strongly criticised any physical concept which is â€Å"independent in its physical properties, having a physical effect, but not itself influenced by physical conditions† [4]. Just a proposed interpretation of a wave function should therefore be justified if this wave function interacts with spacetime. Basing on General Relativity we know that the spacetime is influenced by gravitation. So the first simple test for the new interpretation is to check whether gravitation changes a wave function. Fortunately such an experiment was done. Firstly neutron beam was scattered into two beams: each influenced by the same gravitational field. Secondly the whole apparatus was placed in a way that after scattering the gravitational fields for the first beam and for the second beam were different. By examining the interference pattern it was observed that the quantum-mechanical phase shift of neutrons is caused by their interaction with Earths gravitational field [1]. One can then also speculate that the gravitational field influences a wave function. It can be objected that the proposed explanation of quantum mechanics is contradicted by the conservation of the energy. A particle really going thorough all possible paths would do infinite work. It is not true in the proposed scheme. No procedure could measure such an energy, because those trips take places in a part of a spacetime where no useful time concept exists. If time is immeasurable then the particle can do the work needed to go through all possible paths. However immediately when a working clock is used, a particular path is localised an the energy conservation is saved. It can also be seen from this argument that the Feynmans Path Integral approach is the most natural formulation of Quantum Mechanics. Conclusions The presented arguments lead to the specific interpretation of quantum mechanics. Conceptually the presented considerations show that one can find some guide towards Quantum Physics starting from Relativity and Plancks law. Especially Feynmans Path Integral Formulation emerges in nice way. Some further implication to Cosmology occurs. The Universe filled solely with zero rest-mass particles should be treated as in a superposition state of all possible states. Occurrence of strictly positive masses not separated by event horizon would give the origin to time and states being in a superposition can be reduced to a particular state. It advocates the concept of the Universe wave function. In a black hole singularity time stops and mass density is infinite as is known from Relativity. If one would look at a singularity from the presented point of view one could say that mass density is infinite only for external observer. Because only such an observer has a meaningful concept of time. Infinite density occurs as a consequence of localising all in-falling particles in a point. However as it was explained in the paper if time stops, all particles can occupy the same point in the same â€Å"time† (which exists only for external observer). A possibility of application of the presented scheme will be explored in the future research.
