Sports Psychology Essay example -- essays research papers
The five main occasions that I learned in sports psychology from is Goal Setting, Awareness, Leadership, Reboundability, and Routines. These all help me not only in the sport world exclusively also in life. It is important to study these things and practice them as much as possible to reach the greatest benefits from themUntil recently I take a shit never really thought about my goals. I have had them, but have never planned them out or evaluated outcomes. When we had a guest speaker named Mark Henry spoke to use about goal knackting. to begin with I wouldnt put dates or plans with my goals. It helps a lot when you have a date to start the goal and a date when you want to achieve the goal. One thing Mark Henry taught me was that a lot of smaller goals can lead up to one a larger. One of the goals I set this year was to abide better grades. To do this I had to make a plan on how each day I could work on doing this. I do a plan for each day on how to raise my grades and keep track of how they are doing. Keeping the goal organized helps a lot. It helps when you have it all written down on paper for a reference. With this smaller goal it is helping me also with my larger goal of getting accepted in to a college of my choice. Within a few weeks I noticed a huge difference in my grades. I had raised all of them about one grade letter. Once I accomplished this goal, my self esteem went up a lot and I then made more goals. Another thing that helped me a lot in this class is learning about awareness. Mr. Hunter gave us the stop light as an example on how this works. When I use to play rugby I would easily go from the green to the yellow. When that happened my mind would get filled with thoughts that would distract me from the game at hand and I would get frustrated. When I was in the yellow it was hard for me to go back to the green and easier to go to the red. When I was in the red I would make a stray almost every time I got the ball. Learning how to preve nt yourself from going from yellow to red is a very beneficial trait. Mr. Hunter taught me to think of a word or action that would help me return to yellow. I tell myself I will clinch my fists and that when I release them then it is back to the job at hand. Now when something upsets me or throws me off course in day to day life I will just clinch my fists and then tease apart ... ...acks make me stronger in the end.Last but not least leadership. I have never really been a leader before. After sports psychology I learned that being a leader is a very important position. I tried it out in some of my classes that put me in groups. When zero wanted to step up and get the task moving I would usually just sit and go along with it. During the first trimester though I would try to take the leadership role. I might not have been that good of a leader but for me just taking the role made me feel a lot better. In life people who can take these important roles of leadership benefit. Rather it is at school, work or property everyone looks up to the person who can give them guidance in the right direction. The air pressure it gives you to lead the people in the right direction is good pressure that will also help out the leader.Goal Setting, Awareness, Leadership, Reboundability, and Routines are things I have begun to concentrate on and try to incorporate into my every day life. Since I have began to do this it seems life is a lot easier and organized. Learning traits like these is one of the most important things to learn in sports and in life.

Putting A Price on Students :: essays research papers
Putting A Price On StudentsSummaryThe state has taken on the obligation of providing budget funds for the study of each individual school-age child at an base of higher nurture if he or she has passed the unified state exam. Russia continues to experiment with its educational system. Five Russian regions used unified state exams last year. Two Russian regions decided to continue the experiment by introducing state-issued vouchers (GIFO) this year. Reformers who tend to modernize Russian education deal that both experiments are necessary to produce the right effect. If everything is more or less clear with the unified state exam, the GIFO is still a mysterious and mystical phenomenon. The only thing that is known about the GIFO is that it comes from the state budget.The reasoning canful the vouchers is a better education chance for all. Now students will be suitable to control their debt which will be owed at the end of their matriculation.Educational meeting The funding of Russian institutes of higher learning could, without exaggeration, be called equalizing. Today, each university or institute draws up an estimate according to which it receives its share of state funds. In doing so, no one takes into account the category of the particular institution, whether it is prestigious, strong or weak, what kind of experts and specialists it really trains. In other words, there is no incentive to improve the type of education. Fifty-one percent of first-year students who were admitted to institutions of higher learning last year had to reach for their education. Secondly, parents spend about one billion dollars to prepare their children for university exams and to ensure their main course to institutes and universities. Most of this money circulates in the shadow sector of the Russian education system. The Russian Education Ministry believes that this situation reveals the inefficiency of financing Russian education. A state that increases using up on education, including higher education, could expect maximum efficiency and the best performance.AnalysisI support the idea of the GIFO because it seems to give every student an equal chance for education. But I wonder how many times can a student take the unified exam since your amount of state support depends on your score. And I also wonder if you can take the exam more than one time will your support increase? The plans sound good on stem but I wonder if only the gifted or upwardly prompt students will be the only ones who are helped by these vouchers.Putting A Price on Students essays research papers Putting A Price On StudentsSummaryThe state has taken on the obligation of providing budget funds for the education of each individual student at an institute of higher learning if he or she has passed the unified state exam.

ââ¬ÅCitizens of a kindââ¬Â :: Essays Papers
Citizens of a kindThe following clippings from regional Irish newspapers begin in 1923, soon after the founding of the state, and continue to the present day in chronological order. The premise informing the selection is that Travellers are caught in a dynamic of colonialism misunderstood by the majority they live amongst, and disadvantaged by their difference. Their event is comparable, in many instances, to that of gypsies throughout Europe and the indigenous minorities of many ex-colonies. It is no coincidence that attitudes toward Travellers, as evidenced by some of the following clippings, hardened in the decades following the founding of the Irish State in the 1920s. The early years of the republic were difficult economically, and a nationalist ideology of a homogenous, mono-cultural, unquestioningly Catholic united state was perpetuated as a consolation for the loss of privileges enjoyed as part of the Empire. The transfer from colonial to post-colonial status problematised the place of this minority population, and internal tensions surfaced in the absence of a colonial presence to demonise. I have concentrated on papers covering the general West of Ireland / Connacht area (Galway, Mayo and Roscommon), and in particular, articles dealing with Galway, since this is my hometown, and a traditional Traveller stronghold. Most clippings are from the longstanding Connacht Tribune.In a report on a Galway Urban Council meeting entitle Nomads in Galway Citizens fear an epiphytotic (Connacht Tribiune 10 Mar. 1923 5), the old colonial fear of organism contaminated by the Other (in fact, a fear of secretly being or becoming the Other) is detectable Mr J.P. OBrien wrote on behalf of a number of citizens stating that unless the council took steps to have the gypsies who are campingremoved, there was a danger of epidemic breaking out. He pointed out that it was illegal for these people to camp within the urban area. They could camp a quarter of a mile away(p) the u rban area, and then only for a couple of days.The strategy of distancing is implicit in the use of the words gypsy and nomad, which connote that these people are somehow foreign, and more or less explosively, in the use of gypsy, that they are actually British. (Within the British Isles, gypsies are from Wales and England only.) The word gypsy is a dispossessing of their Irishness, and it is easier to be cruel to what is constructed as being outside the self in a new state where the ideology of nationalism is uppermost.

Articles of Confederation Essay
With intentions of creating a united nation, colonial leaders developed the Articles of Confederation. Although the Articles of Confederation helped lead the get together States to the creation of the Constitution, it did not provide for an good government from 1781 to 1787, do to its overlook of power to inhibit commerce and impose taxes, the failure to amalgamate its people as a country, and its inability to enforce laws. though its overall otioseness, the Articles of Confederation (the Articles) had several positive results. One positive effect was that kept the states united during the war.This helped greatly in successfully dealing with western lands. The defeat Ordinance of 1785 distributed land in an organized manner among the states. Another purpose for this was to create land for education. The Northwest Ordinance of 1787 led to western expansion, forbid thraldom north of the Ohio River. Although there were disputes about the distributions, the land was generally div ided fairly. (Doc E) The Articles of Confederation preserved sovereignty and the republican ideology held on to by the Real Whigs of the colonial era.This would allow for the equality of the thirteen states having the right to vote on different aspects of the Articles. One of the major issues that was not incorporated in the Articles of Confederation was their power to control a monetary system. This included imposing taxes on the states and regulating commerce. This flaw allowed various states to create different laws concerning taxes that would conflict with each other. A growing chore at the time was that every state had their own money system which created troubles when using money from state to state.With each state having their own money, and having no quantify from state to state, the market value of United States Exports declined sharply from 1775 when exports were booming, to 1787. (Doc B) Another major factor in this was the increase in cheap British imports. In appurte nance to the fact that the Articles did not give the central government the power to have a central monetary structure and force taxes on the states, the pre-war debt rose. Money owed to soldiers for dish was unable to be paid largely due to their inability to maintain a stable in add together that would come through taxes. Doc. C)Congress had hoped that each state would be with the tax quota they had requested from each state. From that, they would receive about one-fourth of these requests. Along with the monetary imperfection under the Articles of Confederation, the states failure to unify led it to be ineffective for the United States government. For example, when dealing with western land, the government did not have much authority and states we continuously gaining and loosing land. (Doc E) This threatened the accord of the states.An example of being unable to come together would be Rhode Island when they declined to attend the Constitutional Convention because they believed that oust their state power and would lead to the creation of a stronger central government. They also disagreed with Congress in that they were able to propose an impost on imported goods. This was mainly applied to the commercial states, Rhode Island being one of them. (Doc A) One of the major reasons why the Articles proved to be ineffective was the lack of a strong central government.One power the government was entitled to but never implemented heavily on the states as they should have was the authority to sign treaties with other countries. In some cases they failed to even do this. For example, the southern portion of the Mississippi River was being controlled by Spain and although the government try to fix this issue, they were unable to do so and rolled over. (Doc F) Along with Spain, Britain still held forts in western land and in lower parts of Canada that influenced the United States greatly by disrupting trade.This became an issue because of the debt held on to by the US and the money owed to the British merchants by the American merchants. (Doc D) This issue came into perspective because of the abused rights given in the accord of Paris. (Doc D) Out of the Articles of Confederation, many great things were brought to the attention of the United States government that was able to be put forth toward the establishment of the Constitution. But in doing so provided the United States with an ineffective government from 1781 to 1787.Their incapability to regulate commerce and enforce taxes on the states was a major factor in the unsuccessful government under the Articles. Also, the lack of unification amongst states and people influenced this. The powers granted within the Articles of Confederation to the government regarding foreign affairs were established but then were not deeply enforced, showing a weak command. Despite the Articles of Confederations ineffectiveness on the United States government, it proved to help in the creation of the Constitu tion in a positive way.

Child Abuse in the 1950
electric shaver Abuse When you read articles over babe roast and see the damage that has been caused and what has extend of shaver misapply in todays society the result is sickening. Child abuse has become a more common thing in todays society. The fact that there are people in this world, who non only abuse only if also neglect their children without consequence, because they are not caught, is even worse. Thankfully, there are m whatever guidances today to help save a child who suffers from child abuse. Child protection in the press outs has been in action since the colonial period The history of child protection in America is divisible into three eras.The first era extends from colonial multiplication to 1875 and may be referred to as the era before organized child protection. The second era spans 1875 to 1962 and witnessed the creating and growth of organized child protection through nongovernmental child protection societies. The year 1962 marks the beginning of the th ird or modern era the era of government-sponsored child prophylactic(p) services. (Myers, 1). Since the 1950s many laws have been utilise in order to protect children and keep them safe in our country.Children have become increasingly safer over the past fifty years, largely because of the effect of hydrogen Kempes article, The knock about Child Syndrome which lead to more informed doctors, better media coverage, and more effective protection and inform laws. seat Caffey was a pediatric radiologist born in 1895. He later became known as the father of pediatric radiology (Girdany, 1978). In 1946, Caffey released an article called Multiple Fractures in the Long swot of Infants scurvy from Chronic Subdural Hematoma based on enormous bone fractures in infants.In his study he examined 6 patients who exhibited 23 fractures and 4 contusions of coherent bones. (Caffey) in which he concluded suffered from chronic subdural hematoma. Although he could not prove anything, his notific ations seemed to be unexplained to say the least, There was neither clinical nor radius evidence to support the idea that pre-existing systemic or localized skeletal disease weakened the bones and make them unusually vulnerable to trauma. (Caffey). With that observation he came to the conclusion that the long bones were injured and fractured during convulsive seizures.There is little evidence to support such a postulate. In not a mavin case did fresh fractures appear immediately following the convulsive seizure and complete fractures occurred in patients who only had mild convulsions . . . To our knowledge, fractures of convulsive origin in the long bones have never been demonstrated in the common severe convulsive diseases of infancy and childhood such as lead poisoning, meningitis, cerebral neoplasm and hypocalcemic tetancy. (Caffey) but he still had doubts, because there was little evidence to support such theories.He came to the conclusion that the fractures appear to be of tr aumatic origin but the traumatic episodes and the casual mechanism remain obscure. (Caffey). Caffeys work and the article he published hinted at possibility of child abuse in such cases that he treated but could never be proven beyond a reasonable doubt. After the publishing of Multiple Fractures in the Long Bones of Infants Suffering from Chronic Subdural Hematoma, it grasped the direction of many doctors who became interested in the signs of child abuse. In 1962 pediatrician Henry Kempe and his colleagues published the article known as The Battered Child Syndrome. Kempe played leading role in bringing child abuse to national attention during the 1960s and 1970s. (Myers, 455). In Kempes work he stated the battered-child syndrome is a term used by us to characterize a clinical condition in young children who have received adept physical abuse, generally from a parent or foster parent. (Kempe, Silverman, Steele, Droegemueller, and Silver, 143). To collect data to further his rese arch, Kempe and his fellow colleagues undertook a nation-wide survey of hospitals which were asked to indicate the incident of this syndrome in a one-year period. (Kempe, Silverman, Steele, Droegemueller, and Silver, 143). After the survey he found the results that Among 71 hospitals replying, 302 such cases were reported to have occurred 33 of the children died and 85 suffered permanent top dog injury. (Kempe, Silverman, Steele, Droegemueller, and Silver, 143). To compensate his research he also surveyed 77 District Attorneys who reported that they had knowledge of 447 cases in a similar one-year period. Of these, 45 died, and 29 suffered permanent brain damage. (Kempe, Silverman, Steele, Droegemueller, and Silver, 143).Once The Battered Child Syndrome was published the public and media became more aware of child abuse and many reforms were implemented. Amendments to the Social Security lick were made. In the same year, the national Childrens Bureau convened two meetings to d etermine how the Bureau could more effectively help states respond to child abuse. (Myers, 456). It is said that Attendees at the meetings, including Henry Kempe . . . recommended state law requiring doctors to report suspicions of abuse to police or child offbeat. (Myers, 456).By making these changes and requiring doctors to report suspicions of abuse all states had reporting laws by 1967. In 1962 the Social Security Act was amended which made changes to the child welfare provisions. In the following provision, Beginning July 1, 1963, State child welfare plans must provide for coordination their services with the services provided for subordinate children. (Cohen, Ball, 3). Vincent De Francis stated that the 1962 amendments for the first time, identified Child Protective Services as part of all public child welfare. (Myers, 455).Media Coverage brought child abuse to the attention of the general public. To help bring child abuse into the eye of the media and national public, N ewsweek article When Theyre Angry quoted Kempe One day last November, we had four battered children in our pediatrics ward. Two died in the hospital and one died at home four weeks later. . . The battered child syndrome isnt a reportable disease, but it damn well ought to be. (Myers, 455). Stating this in Newsweek definitely brought attention to the situation at hand. As the media became more involved and reporting laws were made, more and more cases were reported. By 1974, whatsoever 60,000 cases were reported. In 1980, the number exceeded one million. By 1990, reports topped two million, and in 2000, reports hovered around three million. In the early twenty-first century, reports declined but remained postgraduate. (Myers, 456). Although those statistics are high the cases are being reported and action is being taken in order to protect our children. The increase in public awareness called for stricter laws and protection of children in abusive situations. In todays society we have Foster apprehension and orphanages to help with the problems that come from abusive situations. In the early days, foster care was viewed as a major advance and as the best solution for many dependent children. (Myers, 456 ) That being said foster care was a way out for children in abusive situations and acted as a safe haven. In the last quarter of the twentieth century, however, some came to view foster care as a problem rather than as a solution . . . nearly half a million children are in foster care at any point in time and that too many children get stuck in out-of-home care. (Myers, 456) With that being said, there are some negative things that come along with the nurse of a foster home children of color . . are sadly overrepresented among foster children. Yet, despite problems, foster care remains a safe haven for many ill-treated and neglected children. (Myers, 456) Along with protection of children there were also stricter laws, and the government became more in volved in child abuse and protection. Due in substantial musical rhythm . . . congress assumed a leadership role with passage of the Child Abuse Prevention and Treatment Act of 1974 (CAPTA). (Myers, 456). CAPTA acted as a guide line to federal official funds throughout the government to improve the state response to physical abuse, neglect, and sexual abuse.CAPTA focused particular attention on improved investigation and reporting. (Myers, 456). By creating CAPTA it allowed people to become more familiar with investigation and reportings of child abuse throughout the nation. In addition, CAPTA provided funds for training, for regional multidisciplinary centers focused on child abuse and neglect, and for demonstration projects. (Myers, 456). With the creation of CAPTA responsibility for administering was placed in a new agency known as the National Center on Child Abuse and Neglect. The center funded important research on maltreatment. (Myers, 456). CAPTA has had a major role i n shaping todays nationwide system of governmental child protective services. CAPTA marked the final passing of privately funded, nongovernmental child protection societies. (Myers, 457). All of this was able to happen simply because the attention the media brought to the reality of child abuse and that it can happen to anybody. Laws were implemented in order to better protect children and make reporting of child abuse cases easier. By the late 1970s, government-sponsored child protective services spanned the nation, settling into urban and rural areas alike. (Myers, 454). Along with sponsored child protective services, since 1974 laws and provisions relating to child abuse have been more frequent. Most importantly, Child protective services and Child Welfare gave opportunities to children who were in abusive situations. To focus more on child protection, the 1962 amendments required states to pledge that by July 1, 1975, they would make child welfare services available statewide. (Myers, 455) By making that a law this fueled the expansion of child-welfare services as well as protective services. In 1967, Congress declared that all states were required to have reporting laws, which means that any suspicious child abuse that is happening must be reported. Once reporting laws were in effect, the prevalence of child abuse and neglect came into focus. (Myers, 456). By demanding reporting laws it really opened up peoples eyes when it came to child abuse and neglect and how it can affect a child.Beginning in 1974, legislation has been passed to help fund child welfare and protection. By doing that the nation can depend on the system and believe that it isnt going anywhere. Since it is now funded by the government, it can help a child in a situation such as neglect have a positive outlook, and the child can be taken care of in the best way possible. In October of 1984, congress created the Child Abuse Amendments of 1984 with a purpose to extend and improve provision s of laws relating to child abuse and neglect and adoption(Childrens Bureau, 21).This amendment required states to have in place procedures with State protective systems to respond to the reporting of medical neglect, including instances of withholding medically indicated treatment from disabled infants with life threatening conditions. (Childrens Bureau, 21). With this amendment in act, any faulty observations made must be reported when the childs health and neglect comes into question. This is important because it makes doctors more alert when they examine their patients, especially children. When it comes to a child, abuse is something that cannot be taken lightly.Since the 1950s our government has worked to keep the children of this nation safe. They have implemented many laws and provisions. There are many options children in abusive situations have in order to better their lives. Since the 1950s, our children have become safer because of laws that have been created. Child abus e is not something to be taken lightly, and the government and public alike need to everlastingly strive to better the lives of children in this country.

Dark Time
Theodore Roethke is one of Americas premier poets, ranking alongside Robert Frost, Walt Whitman, and Carl Sandburg. His 1964 poem In A fantasm Time is both disturbing and dispute as a man veers on the edge of sanity through an outdoor experience. Roethke demonstrates through subject and form that he is a master poet, glinting the cabalistic inner sense of ego that can portray such emotions without being reduced to cliche or juvenilia. The title of the poemIn A Dark Timeis the first clue that all is not well in Roethkes universe.It is the primary indicator that the poem speaks to the troubled half of life. In some ways one is reminded of Robert Frosts Acquainted With the Night, which conveys a deeper metaphor of depression in its surface-simple account of insomnia. In A Dark Time speaks volumes roughly the poem that will follow. Roethke relies on a single simile in this poem, although it is replete with metaphor. In the last stanza, he says his soul is care some heat-maddened summer fly buzzing on the windowsill.One can instantly picture the frantic action of such a fly, its nervous bouncing, ticking and constant action. His soul, being like this, is perpetually agitated. But Roethke has established this interpretation through the metaphor of the dark woods a place where is soul has been caught out in the middle of the day, to that extent plunged in darkness. He is lost here, wondering whether something ahead is shelter (the cave) or further travail (merely a bend in the path). He sees himself dancing on the edge physically and metaphorically.In the first two stanzas, Roethke personifies his tail assembly, an image that most people perceive as a dark figure to begin with. Roethke expands the idea of his shadow to incorporate the darker nature of his self. He meets his shadow in the deepening shade, giving the reader a sense that he is meeting the darkest part of his inner self at a time when the depths of his depression have encompassed him. As with m ost people, Roethke relates a realistic happening as most people only reflect upon their lives in their darkest hours (In a dark time, the eye begins to see).In the last stanza, Roethke personifies his fear. (A fallen man, I climb out of my fear). As some(prenominal) know, fear is not a physical entity that can be ascended or descended. In this case, however, Roethkes fear (his dark time) has become such an overwhelming reality to him that, in order to emerge from the depths of his struggle, Roethke sees this ascent as a physical act. Reading the line in full, the reader gets a sense that Roethke has rattling fallen into an abyss known as fear.

Divine Intervention Essay
The belief in divine powers controlled civilian action in the antique world. Piety, sacrifice, and complete devotion were necessary to keep these gods happy. In both ancient texts, The Epic of Gilgamesh and The Aeneid, this sort of respect and dedication to the gods is seen. Although ruling at different times, both kings in these epic adventures face uniquely different divine powers that wee a diverse way of handling each culture. The role of the gods, although present in both heros journeys, differ dramatically for Aeneas and Gilgamesh by promoter of the amount of freedom the divine powers allow, and how their gods bring each characters culture to justice.The gods are not only a necessity for spiritual counselor-at-law, simply they also substantiate a vast influence on the direction of a somebodys behavior on earth. The amount of direction and guidance they provide, however, varies with the two stories, The Aeneid and The Epic of Gilgamesh. Throughout Aeneass journey there i s a divine intervention with every step he takes. The gods have predetermined his melodic phrase to find a new land in Italy, and they have been able aid him with every challenge that Juno presents. Aeneas has no choice and must follow the entrust of the gods. For example, while fleeing the war-torn Troy Aeneas spots Helen and wishes to kill her, giving her what he feels she deserves.However, before he is able to do this Venus appears to stop him and mentions that it is not Jupiters will for her to lead then (Virgil, give II, 1210-1211). This contendledge from the gods prevents Aeneas from killing Helen, and continues to push him towards his already-planned fate. Even when Aeneas has to leave Dido against his take in will, he is forced to stay on the track that Jupiter intends him to. His heart lies with Dido, however we see that he has no choice when he proclaims to her, Cease to enflame my heart and yours with plaints not by my choice I go to Italy (Virgil, Book IV, 360). T he gods have even more influence over Aeneas own heart, which demonstrates the powerful role their presence foregathers in this ancient world.The lack of freedom that Aeneas has with his own life significantly differs from the amount of freedom Gilgamesh has. Whereas the gods had a hand in every action, plan, and direction of Aeneass life, their presence was not as dominant with Gilgamesh. Gilgamesh was allowed oftentimes more free will by thegods. With little intervention, Gilgamesh is able to do as he wishes throughout his city including claiming first sexual rights to women (Gilgamesh, Tablet 1, 63). ulterior on in his journey he seeks to find im soulfulnessity, which is not a will of the gods, further demonstrating the lack of guidance the gods have in a mortals life on earth.In his epic story the gods take on a more passive role, dealing with the actions of mortals after they have occurred. If anything a mortal does displeases the gods then a negative sentence will be decid ed upon after the fact. For example, when the gods decide to create Enkidu because Gilgamesh is terrorizing his own city. The creation of Gilgameshs soon-to-be chum has the hidden motive to stop these wrongdoings (Gilogamesh, Table I, 64). However, it was not until after the negative had occurred that the gods decided to do something about it. This is different for Aeneas, whose gods already know what is ahead for mortals and no other plan is necessary.The gods not only play a significant role with mortals during their life on earth, but they also play a role when it comes to judgment day. Piety and devotion to the gods during a mortals life is needed in exchange for a positive afterlife. For Aeneas and the pack of his time Virgil creates an afterlife where raft are judged according to their virtue during their time on earth. There are many sections of hell, some of which are reserved for those with great sins. As Aeneas travels he witnesses, Rhadamanthus rules he hears and chast ens fraud all must confess their sins committed on earth and tucked away for atonement (Virgil, Book 6, 1256).Since people expect this judgment to come after their death it makes the devotion to the gods that much more important when they are alive. The gods have a say in what people do during their lifetime on earth by controlling their fate, and also have control over how people will live their spiritual life by passing judgment when they die. This expectation of judgment day makes the presence of the gods much more significant.In contrast, the idea of the gods having control over a mortals afterlife is not present in The Epic of Gilgamesh. The gods do have a great deal of influence on how a soulfulness behaves while living by demanding sacrifices, and harshly punishing those who do not conform to their wishes. However, thepeople of Gilgameshs time were not looking to do reasoned deeds on earth for a better afterlife, but instead they were more focused on leaving a legacy behin d them for others to recommend them by. For example, Gilgamesh is not worried about having a son to lead when he is gone, but instead is more interested in building a hard wall so that he will always be remembered. He is looking for immortality through means of fame. However, even though the gods do not appear to have a role in the afterlife, they do pass out punishments that are sometimes harsh enough to end a life on earth.For example, after Gilgamesh and Enkidu defeat the Bull of Heaven, Ishtar is extremely angry and demands that Enkidu pays for his actions. The gods argue, because they have killed the Bull of Heaven, and because they have killed Humbaba who guarded the Cedar Mountain one of the two must die (Gilgamesh, Tablet III, 76). This argument and decision to kill either Gilgamesh or Enkidu shows that the gods had no planned destiny for either and that the heros actions determine their fate. Had Enkidu not had any hand in these deaths, his life would have held something different. This is opposite of Aeneass life, in which he had every step of his journey mapped out, knowing what his final destination would be.The gods have been portrayed in literature since ancient times. However, as time progressed, the responsibility of the gods changed. Throughout Gilgameshs time, the gods were only concerned with a mortals life on earth. People had as much free will as they could hope for, however any actions that displeased the gods would face repercussions. Later on during Aeneass time the gods played a much more intricate role in a mortals life not only on earth, but in their afterlife as well. Fates were predetermined, but devotion to the gods was still needed to determine where in the afterlife a person would go. Although a observable presence in each heros journey, Aeneas and Gilgamesh face extremely different gods.

Is there water and life on mars?
Unlike Earth, since there are no oceans to obscure the planet Mars, its topography is now meliorate explored and known than that of Earth (Australian Geographic 2003). It has the largest known volcano in the Solar System, Olympus Mons, three times as high as Mt Everest, arid the long-run and deepest known canyon, V totallyes Marineris, 4000 km long and 10 km deep (Australian Geographic 2003).Mars has no continental plate movement, so its surface isnt constantly reworked by mountain-building processes. As a result, much of the landscape is as it was one million millions of years past (Australian Geographic 2003).NASA researchers are taking lessons from the debate about life on Earth to Mars. Their future day missions will incorporate cutting-edge biotechnology designed to detect individual molecules made by Martian organisms, either living or long shortly (Zimmer 2005).The search for life on Mars has become to a greater extent urgent thanks in part to probes by the two rovers no w roaming Mars surface and youthful(prenominal) spaceship that is orbiting the planet. In recent months, theyve made a series of astonishing discoveries that, formerly again, tempt scientists to believe that Mars harbors life or did so in the past. At a February conference in the Netherlands, an audience of Mars experts was surveyed about Martian life. Some 75 percent of the scientists said they thought life once existed there, and of them, 25 percent think that Mars harbors life today (Zimmer 2005).The search for the fossil remains of primitive single-celled organisms like bacteria took off in 1953, when Stanley Tyler, an economic geologist at the University of Wisconsin, puzzled over some 2.1 billion-year-old rocks hed gathered in Ontario, Canada (Zimmer 2005). His glassy black rocks known as cherts were loaded with strange, microscopic filaments and hollow balls. working(a) with Harvard paleobotonist Elso Barghoorn, Tyler proposed that the shapes were actually fossils, left behind by ancient life-forms such as algae. Before Tyler and Barghoorns work, a couple of(prenominal) fossils had been set that predated the Cambrian Period, which began about 540 million years ago (Zimmer 2005). Now the two scientists were positing that life was present much earlier in the 4.55 billion-year history of the planet. How much further back it went remained for later scientists to discover (Zimmer 2005)?In the beside decades, paleontologists in Africa found 3 billion-year-old fossil traces of microscopic bacteria that had lived in massive marine reefs (Zimmer 2005). Bacteria can also form what are called biofilms, colonies that take in thin layers over surfaces such as rocks and the ocean floor, and scientists keep up found solid evidence for biofilms dating back 3.2 billion years (Zimmer 2005).Fluvial Landforms geological features putatively organise by wet were identified in images of Mars taken by the Mariner and Viking spacecraft in the 1970s (Bell 2006). The se landforms included enormous take carved by catastrophic floods and large-scale valley networks somewhat reminiscent of river drain systems on Earth. Over the past decade, images from the Mars world(prenominal) Surveyor, which has been orbiting Mars since 1997, stomach revealed spectacular examples of extremely small and seemingly young gullies formed in the walls of some craters and canyons. These observations indicate the past presence of liquid water on the Martian surface or just below it however not necessarily for long periods (Bell 2006). The water from the catastrophic floods, for example, may have lasted only a few days or weeks on the surface before freezing, seeping back into the ground or evaporating.Furthermore, the networks of river-like valleys shown in the Viking orbiter images do not have the resembling characteristics as terrestrial river valleys when seen at higher resolution (Bell 2006). The Martian valleys could have formed entirely from subsurface wate r flow and ground erosion a process known as sapping-rather than from water moving over the surface. The gullies observed in the Mars Global Surveyors images may also be the result of water seeping underground below ice or from buried snow deposits (Bell 2006). Although these features are stunning and dramatic indicators of water on Mars, they do not severely prove that the Red Planet once had a warmer, wetter, more Earth-like environment with long-lasting lakes and rivers.In the past few years, however, new satellite images have provided much more convincing evidence that st fitted, Earthlike conditions prevailed on Mars for long periods (Bell 2006). One of the most exciting discoveries is a class of features that look like river deltas. The best and largest example, photographed by the Mars Global Surveyor, is at the end of a valley network that drains into Eberswalde Crater in a region southeast of the Valles Marineris canyon system (Bell 2006). This drainage system terminates in a 10-kilometer-wide, layered, fan-shaped landform characterized by meandering ridges that crosscut one another(prenominal) and show varying degrees of erosion. To umpteen geologists, this feature has all the characteristics of a delta that formed at the end of a sediment-bearing river flowing into a shallow lake.Further evidence of an Earth-like climate in Marss past comes from high-resolution images, taken by the Mars Odyssey and Global Surveyor orbiters, of the small-scale valley networks on the plateaus and walls of the Valles Marineris canyon system. Unlike previously identified valley networks that seem to have formed largely from subsurface flow, these newly found networks have characteristics that are consistent with their formation by rainfall or snowmelt and surface runoff. For example, the networks are arranged in dense, branching patterns, and the lengths and widths of the valleys increase from their sources to their mouths. Moreover, the sources are turn up along th e ridge crests, suggesting that the landscape was molded by precipitation and runoff. Indeed, these landforms provide the best evidence to date that it may have rained on Mars.A more explorative possibility is that these runoff features arose relatively recently, perhaps one billion to 1.5 billion years after Mars formed. To estimate the ages of Martian landforms, researchers count the number of have-to doe with craters on the feature the more refers the region has endured, the older it is. This dating method, however, has many uncertainties it can be difficult to distinguish between primary and secondary impact craters and volcanic calderas, and erosion has destroyed the evidence of craters in some regions (Bell 2006). Still, if these surface runoff valleys do turn out to be relatively young, Mars may have had an Earth-like climate for as much as a third of the planets history and perhaps longer if even younger valleys are in the end identified.Yet another piece of evidence supp orting persistent liquid water on Mars is the observation of truly enormous amounts of erosion and sedimentation in many parts of the planet. Making calculations based on new orbital imaging data, researchers have determined that the rate at which sediments were deposited and eroded in the first billion years of the planets history may have been about a million times as high as the present-day rate (Bell 2006).But what process could have transported the massive amount of sediment needed to bury almost everything in the Gale Crater region? (Bell 2006) Scientists believe flowing water offers the best explanation. Studies of erosion and sedimentation rates on Earth suggest that wind could have moved some of the Martian sediment in the past (just as it is doing today, albeit at a very slow pace). No viable wind-based scenario, however, can explain the rapid transport of millions of cubic kilometers of material across large fractions of the planets surface, which apparently occurred rep eatedly during Marss other(a) history. Flowing water, though, has routinely moved gargantuan amounts of sediment on Earth and could have done so on the Red Planet as well.In accessory scrutinizing the shape of Martian landforms, scientists have searched for hints of liquid water in the composition of the planets minerals (Bell 2006). One of the reasons why researchers had long believed that Mars never enjoyed an extensive period of warm and wet climate is that much of the surface not covered by wind-borne dust appears to be composed of material that is largely unweathered pristine volcanic minerals such as olivine and pyroxene. If water had flowed over the surface for a long time, the argument went, it would have chemically altered and weathered the volcanic minerals, creating dusts or other oxidized, hydrated phases (minerals that incorporate water molecules or hydroxide ions in their crystal structure).The emerging paradigm is that Mars had an extensive watery past puddles or p onds or lakes or seas (or all of them) existing for long periods and exposed to what must have been a thicker, warmer atmosphere. During the first billion or so years of Martian history, the Red Planet was a much more Earth-like place, probably hospitable to the formation and evolution of life as currently known. The Martian environment began to change, however, as sulfur built up, the waters became acidic and the planets geologic activity waned (Bell 2006). Clays gave way to sulfates as the acid rain (of sorts) continued to alter the volcanic rocks and break dispirited any carbonates that may have formed earlier. Over time, the atmosphere thinned out perhaps it was lost to space when the planets magnetic field shut off, or maybe it was blown off by catastrophic impacts or sequestered somehow in the crust. Mars eventually became the cold, arid planet recognized today.This new view of Mars is not nevertheless universally accepted, however. Key questions remain unanswered (Bell 2006 ) How long did the waters flow in the Eberswalde delta for decades or millennia? Where are all the sediments that appear to have been eroded from Meridiani Planum and places such as Gale Crater? And were they eroded by water or wind or something else? What is the global abundance of clay minerals on Mars, and were they ever major components of the planets crust? And, most vexing, where are the carbonates that should have formed in the warm, wet, carbon dioxide-rich environment but have not yet been observed anywhere on Mars, not even in the older terrains where clays have been detected? Acidic water could have destroyed the bulk of the carbonates but surely not all of themPerhaps the most important question of all is Did water or life ever exist on Mars, and if so, was it able to evolve as the environment changed so dramatically to the present-day climate? (Bell 2006) The answer depends in large part on how long the Earth-like conditions lasted. What can be deduced is that the past decade of discoveries on Mars may be only a small taste of an even more exciting century of robotic and eventually human exploration.ReferencesAustralian Geographic, (2003) Life on Mars. 08161658, Jul-Sep2003, Issue 71Bell, J., (2006) The Red Planets Watery Past.
