Hero Worship Essay -- essays papers

Hero Worship When asked to conjure up descriptions of a hero or heroism, many people would imagine similar scenes. The firefighters pulling a family from a burning building, a soldier saving his platoon from certain death, rescue workers pulling a stranded mountain climber from a precarious ledge, and the Knights of the Round Table saving a damsel in distress, are all examples of the "common" hero. Many people display heroism in everyday life but are rarely recognized either by their peers or by the media. Heroism can be traced back in time as early as mythology has been present. People of that era felt a need to worship super-beings who could solve their problems. Current examples reflecting that age are evident on television today. Both "Hercules" and "Xena: The Warrior Princess" are ever present to save the peasants from the evil and cunning warlords. Mythological heroes had their deeds exaggerated as the stories were passed by word of mouth from person to person. Storytellers have always felt a need to liven up their stories and as they passed them from generation to generation, the stories continued to grow. Everyone knows what heroism is, but describing it can be difficult. Gallantry, valor, bravery, and courage are all traits normally associated with heroism. For the people who risk or sacrifice their own lives in an acts of selflessness, these words are accurate in describing heroism. Few would dispute that a person who pulls another from a burning flipped-over car ready to explode does show heroism. The news media is always looking for acts of heroism as they make for captivating news. Just recently, a fourth grade boy grabbed the wheel of a school bus after it was involved in an accident. Th... ...? There may be several other terms to call these superstars, but to call them heroes or to describe their actions as showing heroism is ridiculous. They may do other deeds away from the sport that could earn them this distinction, but on the playing field it is hard to imagine them rising to the level of a hero. Heroism is shown in many varied situations. The person who can make a split second decision to save someone is no doubt heroic. What does this say about the person who has time to decide a course of action and willingly helps someone? These types of heroes, the dedicated teacher, foster parents, counselors and a myriad of other examples, may show the most heroism of all by choosing to save a life. It is shameful that we do not recognize these people more often and have these stories told by the media and peers. They may be the greatest heroes of all.

Why was Malthus wrong about Japan?

Today Japan is a highly developed first world country with a vast population and a booming economy. The demographic history of Japan and how it reached this renowned economic status has been the focus of much theorising and has engaged the minds of many demographers, economists and historians for centuries. Japan is unique in the way its population has changed and its economy has developed without the stimulus of overseas markets. It does not boast the best physical landscape, being 85 percent mountainous, and it is not well endowed in terms of resources. Despite these negative attributes however, Japan has developed, and to such an extent it can now boast one of the worlds leading economies. Indeed Japan was the only country outside the western world to have developed at a similar rate. In the 18th century a Swedish doctor, P. Thunberg commented on Japan, ‘Of all the countries that inhabit the three largest parts of the globe, the Japanese deserved to be ranked first, and to be compared with the Europeans. ‘ (Modern Japan, P. Duus. ) It stands to reason therefore that Japan's history merits such a wealth of discussion amongst academics. Part of Japan's success as a country has to be attributed to its longstanding political regime. For centuries Japan was an empire ruled by an emperor based at Kyoto. From the 12th century however Japan was governed by Shogun (military leaders) who oversaw the day-to-day life of the Japanese people. The emperor, in effect, was under house arrest, taking a submissive role being more of a spiritual leader to the people. The year 1600 saw an important event for the political governing of Japan. It was in this year that a battle (Sekigahara) established the supremacy of the Tokugawa family as ruling shoguns. From 1600 to 1868 this family ruled and these 268 years of Japan's history became known as the Tokugawa period. It is this period that is of fascination to many demographers as during this time Japan experienced stagnation in its population but it also seemed to be the onset of its economic success. From the early 18th century to the Meiji restoration in 1868 Japan's population stayed at around 33 million. It is this 150-year period of stagnation that is of interest to studiers of the demographic history of Japan. There is also much discussion as to whether the population as it was, was inextricably linked to economic growth or vice versa. Searches for explanation of population trends date back centuries. One of the earliest and probably the most famous explanation of observed population figures in the world in general, was put forward by the Rev. Thomas R. Malthus in the 18th century. In 1798 Malthus's ‘Essay on Population' was published, in which he wrote at length on past, present and future population trends of mankind. His most famous stance on population levels was that ‘population, when unchecked increases in geometrical ratio; subsistence only in an arithmetical ratio. (Malthusian Population Theory, McCleary. ) He believed that mans (sic) power to produce population is greater than his power to produce subsistence, thus meaning that that the population of a country was constantly held in check by misery and vice. From this a simple model is produced illustrating the point that if populations increases; food prices will increase; real income will decrease; and thus mortality will increase (figure 1. ) The ultimate check according to his works was the want of food, but this was never an immediate check except in the case of actual famines. The constant checks can be classified into two sets, preventative and positive. Positive checks are multifarious and include such components as exposure to the elements, epidemics, war, plagues, famines and extreme poverty. The preventative checks can be further sub-classified into vice and non-vice. According to Malthus however, there is only one preventative check that can be classified as vice and this is moral restraint. The consideration of moral restraint was a latter thought from Malthus, added to his ‘essay' in 1803. From this a more optimistic model of possibility was constructed (Fig 2. ) The two checks vary inversely from one another and can be in operation with varying affect according to the society in which there are operational. The situation as it was in Japan must have had some constituent that caused the observed trends in population. If Malthus's theory is believed to have been operational in Japan then some sort of check was holding the population at its stagnated rate. Japan, unlike Europe at the time was a closed system. Emigration was unheard of and likewise nobody entered the country. Internal migration was also low, although would not have affected population figures. This was mainly due the Tokugawa establishing a period of isolation, cutting Japan off from the rest of the trading world. In terms of Japans population this meant that migration was not responsible for the stagnation, therefore according to Malthus it must be due to high mortality rates and/or moral restraint alone. Malthus travelled to various European countries to study their population trends in order to supplement the work in his first essay. He did not however make it as far as Asia, but did manage to comment on Japan and China in his work. He tended to make generalisations about Japan based on his thoughts about China, believing that in both of these countries moral restraint was not practiced, as it was only adapted to Western Europe. His work led him to believe that in Japan and China marriage was universal and occurred at a very young age. Taking this into account, Malthus attributed positive checks on population to the cause of the stagnation the Tokugawa period. Included in the positive checks Malthus believed occurred in Japan was the act of infanticide or ‘mabiki', literally meaning ‘thinning out. ‘ Again he depicted Japan as being similar to China, but whether he was wrongly casting aspersions about Japan or whether infanticide was one of the components accountable for the population trends is another area that has been widely debated. Many people in this field of work since Malthus have devised various explanations as to the cause of Japans stagnation, and many have been curious as to whether Malthus was right about Japan. In order to deem Malthus right or wrong on this topic information on fertility and mortality levels as well as the marriage system and evidence of infanticide is needed. Early studiers of Japan's history found a way of gathering such information. During the Tokugawa period a registration system, known as Shumon Aratame Cho, was devised (mainly for tax reasons) that recorded births, deaths and other such information for villages in Japan. By studying, what were tantamount to an early form of census, family reconstitution is possible and a better idea of the overall demographic change at that time in Japan is given. Generations of population historians have performed village studies and different generations have varying ideas about the trend in population. The first generation of population historians believed Malthusian checks to be in action in Japan. Subsequent work has questioned this conclusion and many other avenues of thought have been opened up. Levels of fertility are related to marital patterns. This is an area that Malthus had decidedly definite views on in Japan. A control on marriage may have been responsible for the stagnation experienced between 1700 and 1850. This kind of population control may have been conducted in Japan in order to yield positive benefits from lower fertility levels, managed food prices and improved real incomes. Malthus believed that nuptuality in China and Japan was universal and occurred at a young age. He did not believe that controls on marriage could occur in Japan as outside Western Europe h thought that ‘the passion between the sexes is necessary' and cannot be overcome (Malthusian Population Theory, McCleary. From studies of nuptuality records (including components such as age at marrying and proportion of people ever married) it is shown that marriage was universal in Japan but was not at such an early age as it was in China. If nuptuality levels for Japan are compared with England and China for the same time period, then Japan falls somewhere in the middle (see fig 3. ) Universal marrying would suggest high levels of fertility but as discussed this was not the case in Tokugawa Japan. The issue of marrying at a later age can account for low levels of fertility, and possible reduced fecundability in women. Other factors can be attributed to fertility levels and many studies have been carried out in this area. T. C Smith, part of a later generation of population historians, conducted a study of a village which he named ‘Nakahara,' to give an overall general pattern of what was occurring in Japan at this time. Smith looked at fertility levels of the village and constructed fertility curves to examine the possibility of infanticide. The curves showed low levels of fertility, and were convex suggesting that there was an absence of birth control in the village. This adheres loosely to the standard levels of fertility at the time; although the figures in question were lower (fertility levels were naturally low in Tokugawa Japan, lower than pre-industrial Europe. ) Smith believed that the low levels of fertility were due not only to factors such spacing and lactational amenorrhea, as put forward by some of his contemporaries (e. g. Cornell), but also to the practice of infanticide. If Smith's study is consistent with the rest of Japan, then Malthus's theory would be true. However fertility curves alone do not prove beyond doubt that infanticide was occurring. L. Cornell believed the reasons for the low levels of fertility could be explained by factors other than infanticide. She believed the low level of fertility in general in Japan was a result of cultural rather than structural patterns. One of the main reasons put forward for this was the long lactation periods of Japanese mothers. It is biologically proven that the longer the lactation period after birth the harder it is for a couple to conceive their next child. This, Cornell attributes to the observed low fertility levels. Another reason put forward is migration patterns of males in villages at that time, causing a reduction in fecundability. Migration to castle towns, where employment had a large pulling power, was seasonal in villages and as a result of long periods of migration, fecundability decreased and fertility was kept at a low level. Cornell believed that these factors not deliberate controls on family size by the practice of infanticide as other academics believed, caused low levels of fertility in Japan. This was brought about by controls on society by over-riding cultural trends. Smith however, had evidence other than fertility curves to support his claim about infanticide. He studied the sex bias in families in Nakahara to add weight to his argument. He believed that the sex of the next child in a family was enforced by infanticide. Assumptions are easily made that this practice accords with the widely heard of folklore that males were the preferred sex in Japanese households, therefore one would expect the sex ratio to be male biased. However Smith found from his studies that the sex of the next child was not biased to males. He tabulated the evidence, which showed that in a family with predominantly male children, the next child was more likely to be female, and in families that had equal number of male and female children, the next child was most likely to be a male. The opposite was true in families with predominantly female children. However sex selectiveness was not found in other studies, for example in a study by Hayami, there was no evidence of sex selectiveness in families. Smith used this evidence to suggest that infanticide was a means of family limitation in Japan. Another piece evidence he found for the practice of infanticide was that small landholders had fewer children than large landholders, suggesting that family limitation was practiced as a long-term plan, so as to not put financial on the existing family and to maintain living standards. This idea has been rejected however by other authors such as Hanley and Yamamura who believed that infanticide was not only practised by peasants and poor families, but also by the rich who chose to limit their family in order to husband assets. Many authors speculate that infanticide was also practiced to limit the number of male heirs in a family and lessen the competition for family headship. On the matter of infanticide in Japan, contrasting ideas make it difficult to conclude if Malthus was correct in his assumption. However what can be concluded is that villages would have undoubtedly varied in their practices and beliefs. From a persons study of one village it would be wrong to conclude that infanticide was or was not practised in general in Japan. What would be a fair assumption would be to say that infanticide probably was operational in some areas and not in others. However it seems unlikely that infanticide alone, occurring in some areas would lead to the stagnated population that occurred in Japan at this time. Other checks on population must now be looked at to prove or disprove Malthus's theory. It is a given that fertility levels were low in Tokugawa Japan, so according to Malthus mortality must be a contributing factor of the population stagnation. From the Shumon Aratame Cho it is difficult to gain an idea of mortality levels, especially infant mortality. It has been estimated (Cornell) that by as late as 1926 a quarter of all deaths in Japan were infants. In the early Tokugawa period death rates were high and fluctuating. The life expectancy at birth at this time was in the low thirties. Epidemics as a constant check, proposed by Malthus, occurred regularly in Japan; however by about the 16th century the population was large enough to support such disasters. There were also some wide spread famines, particularly bad ones occurring in the 1730's, 1780's and the 1830's, which obviously would have made a dent in population figures. However there is a tendency for populations to recover quickly from famines, and many people would have simply moved away from the area. These two Malthusian checks seem not to have had a large impact on death rates, suggesting Malthus was wrong about Japan in this case in point. Death rates not associated with widespread disasters, must also be take into account. Mortality levels were generally higher in the cities, of which there were about 200 at this time, than in the countryside. An increase in the number of people living in cities could account for a high national mortality level; however improvements in the standard of living meant that death rates actually decreased in these areas. It seems that in this period of Japan's history contrasting factors were at work keeping the death rates at a constant level. Warfare decreased at the beginning of the Tokugawa period, lowering death rates; but epidemics were introduced, increasing the rates. Similarly death rates increased slightly as cities grew, but the improvements of living standards combated this increase. Malthus was correct in the sense that checks on population were occurring in Tokugawa Japan, however he did not account for the fact that Japan with a completely different culture and set of traditions from Europe, would have had different ‘checks' on the population working in opposition to the ones he proposed. A picture is now appearing of life in Tokugawa Japan. Fertility levels were low; mortality levels were high and fluctuating at the start of this period but then decreased towards the end. These two demographic variables can account in part for the population remaining constant for so many years, but it is not exactly in accordance with what Malthus thought about Japan. In reality Japan was much more akin to England in terms of its demography than China. Malthus was wrong in this case as well. He presumed Japan to be dissimilar to European countries and because of its locality in relation to China, to be much more alike it neighbouring country. Malthus had some general thoughts on population, not specific to Japan, but which are also wrong in Japans case. Malthus believed that ‘man (sic) does not like hard work', and this is why subsistence cannot take keep pace with population. This would ultimately lead to a positive check on population, which Malthus did believe was occurring in Japan. From the time of the Tokugawa period to present day, the people of Japan have shown to have been hardworking, which is represented in the level of their economic success today. From the 17th century agriculture was the main employment sector in Japan. During this century agriculture took off at a vast rate and began to keep pace with the growing number of mouths. As the population slowed and productivity continued to increase, the per capita food supply also increased. Small-scale cultivators dominated the agricultural economy in Tokugawa Japan, but this was only the starting point of the economic transitional change in Japan. By the late Tokugawa period, ‘proto-industrialsation', a term referring to the production of goods for distant markets was underway. New technologies spread and output of products such as soy sauce, bean paste and vegetable oil was a substantial proportion of all non-agricultural output. Proto-industialisation was concentrated in rural areas, which meant migration to large cities slowed, which in turn would have affected mortality rates, as mortality was consistently higher in these areas. In this case Malthus was also wrong in his assumptions about Japan. The population did not grow in a geometric ratio whilst the subsistence only grew in an arithmetical ratio. In fact quite the opposite occurred during the Tokugawa period in Japan. Overall it seems Malthus was wrong in most of his assumptions about Japan, such as universally low ages of marriage, moral restraint not being practised and widespread infanticide. However he did touch upon factors that operated in Japan as they did in many other countries at that time, such as family limitation and preventative checks affecting population numbers. In fact given the very little first hand knowledge Malthus actually knew about Japan, the only way his speculations could have been correct would have been purely by chance, which as highlighted is the not the case. Malthus was incorrect in his assumptions about the extent to which population-influencing factors occurred in Japan. Never the less he gave many population historians a foothold to further investigate the demographics of historic Japan.

These ideas were all working together to help achieve HitlerÂÆ'ÂÆ'‚Â ­s plans of conquest. Though it is argued that a lot of these ideas were more of a hindrance, than a help. One of the principle ideas of a fascist state is total control. Hitler used this principle to make the task of achieving all his other goals much easier. "The Reichstag has passed the following law the government is also able to pass laws."

By Passing these laws, Hitler stood alone, as the sole dictator of Germany.By doing this, Hitler gained a lot of support, as well as a lot of criticism. But Hitler was able to use this total control to stop most the criticism turning into outright opposition. A lot of this power was filtered throughout society, and numerous changes took place. This Generally translated into the reduction of civil rights the people held. This meant things like unions were outlawed, political opinion was outlawed, freedom of speech was outlawed, freedom of press was outlawed, Hitler needed to gain 50% of the Reichstag to gain power. This meant that he had to appeal to many different groups if he was to gain power. He did this by offering something to almost everyone. The graph below shows the amount of the Reichstag the Nazi party held in March 1933. This was still not enough to gain power. Hitler was forced to form a...

To Do vs. To Make

To Do vs. To Make To Do vs. To Make To Do vs. To Make By Maeve Maddox Pointing out that some languages, like Russian, have only one verb to express the meanings of English make and do, a reader requests a little guidance: Please could you explain the difference between the verbs â€Å"to do† and â€Å"to make.† Is there some kind of formula or method? Would that I could postulate some foolproof rule for knowing when to use do and when to use make. Some general guidelines do exist, but for many of the idioms, memorization is the ESL speaker’s only recourse. Generally speaking, the verb do and its forms are used to talk about duties, jobs, or leisure activities: England expects that every man will do his duty. Who does your hair? He’s doing time for assault. She can’t do enough for that lay-about husband of hers. Jake does the crossword every morning on the train. Have you done your homework? The verb make is used to talk about constructing, creating, or performing something: The company has made an offer on a new building. Excuse me while I make a phone call. The child made a face behind the teacher’s back. The builders are making progress on the house. Time is running out; we must make a decision now. We tried to move without making a noise. It’s possible to use do with an adverb: I hope he will do well there. He did badly in his last job. Make is usually followed by a noun: make the bed make amends make a mistake make a visit make a speech Exceptions are the idioms â€Å"to make nice† (behave in an agreeable manner), and â€Å"to make do† (get along with what one has†): His mother told him to make nice with the neighbor’s children. As we haven’t the money for a new car, we shall have to make do with this one. A great many expressions that are used with make can be rephrased with verbs that correspond to the noun that follows make or with another verb: to make a confession > to confess to make a visit > to visit to make a suggestion > to suggest to make a face > to grimace to make believe > to imagine Want to improve your English in five minutes a day?

Should football managers be sacked when results (on the field) are poor - Essay Example A football manager can have the best players in the world, but without credible managerial skills, less talented players who have a better managing team will beat his team. Each player has their own talents, qualities and strengths that proper workout on a daily basis that is meant to sustain morale, motivation and competence the player’s capabilities will not be portrayed in the games. They will be wasted. The secret to football success is in the backroom stuff and management. The best way to ensure staff competence is by understanding what the different football manager stuff attributes mean for training, transfer handling and scouting- this is what is called the ‘non-play attributes’. The decision to hire or sack a manager implies the consideration of aspects linked to environmental pressures, the importance of experience and skill of the manager and the emotional empathy of the manager with the institution. It is important that the manager be sacked based of f ield performance because just as Tena said, there are other external factors to be considered. These factors include the sponsors, the fans, the stakeholders, and the prestige of the football club among others. If a team keeps losing, then there is pressure from these external attributes on the management to take measures towards the rectification of the problem. These measures may lead to the sacking of the manager and other staff members. ... If a team keeps losing, then there is pressure from these external attributes on the management to take measures towards the rectification of the problem. These measures may lead to the sacking of the manager and other staff members. Apart from external factors, there are internal factors that would lead to the sacking of a manager in football. Paolo Di Canio was sacked from being Sunderland’s manager after a player rebellion where several players refused to play for him again. This made it impossible for him to continue managing the team (The telegraph, 2013:16). For the effective management of a football club, the manager should show certain coaching attributes that he should ensure the players are good. These include; attacking, defending goalkeeping coaching and fitness. The lack of these skills will lead to game loses and so if the manager cannot ensure proper training of the players then he should be sacked. The manager should also have a good mental capability i.e. his ability to observe, and act upon an individual’s state of mind and be able to act accordingly. Apart from this, the manager’s ability to work with the youth should be a contributing factor to how well the team will act in the games. The relationship between the players and the manager needs to be good for there to be effective management and good results. It this relationship is compromised, for example, if the players feel that the management is like a dictatorship, or there is no respect for the management, then the manager will not be effective in his managerial duties, and he should therefore be replaced. These are some of the factors that will lead to poor performance; the manager should be replaced when the team has poor performance because it is a

The Movie Fight Club Review Example | Topics and Well Written Essays - 750 words

The Fight Club - Movie Review Example Although one can argue that the narrator makes more use of his mental capacity as evidenced by his imagining Tyler to the point that he thinks Durden is a real person, in the Narrator’s mind it is still the use of the body thru fighting and having sex which is dominant. Furthermore, this also serves as proof to the disorganized thoughts of the person.An important matter that faces us now is how to make sense of the narrator’s creation of Tyler. Was he trying to project himself as a hero? Deep inside, was he actually a person fond of out-of-the-norm sexual practices? These are questions that must be addressed because these characteristics are for an Eros person and not for Thanatos.For sure, the Narrator made Tyler as a hero who gave meaning to the life of other persons. We argue that this is not the case. Tyler is a separate entity and not the narrator himself. It is not the Narrator consciously projecting himself as the hero. What the Narrator is actually committing wa s an act of transference where he transfers his reason or ‘consciousness’ to Tyler. Due to his desperation because of the flaws in his character, he tries to endow another person his consciousness and make that individual make the world know of his angst. Since Tyler was only a product of the subconscious and is therefore unreal and since the dominant behavior of the person is as the Narrator in real, conscious life, we can, therefore, say it was Tyler who was an Eros while the Narrator was a Thanatos.... Was he trying to project himself as a hero Deep inside, was he actually a person fond of out-of-the-norm sexual practices These are questions that must be addressed because these characteristics are for an Eros person and not for Thanatos. For sure, the Narrator made Tyler as a hero who gave meaning to the life of other persons. But the question is, was Tyler essentially the Narrator We argue that this is not the case. Tyler is a separate entity and not the narrator himself. It is not the Narrator consciously projecting himself as the hero. What the Narrator is actually committing was an act of transference where he transfers his reason or 'consciousness' to Tyler. Due to his desperation because of the flaws in his character, he tries to endow another person his consciousness and make that individual make the world know of his angst. Since Tyler was only a product of the subconscious and is therefore unreal and since the dominant behavior of the person is as the Narrator in real, conscious life, we can therefore say it was Tyler who was an Eros while the Narrator was a Thanatos. Having an Eros mentality leads to many worries and frustrations while having a Thanatos character results to a life devoid of meaning. Being a rebellion can be fulfilling but only for a short time. In the end it leads to regret and what-could-have-been statements. What then could lead to a happy life There many ways in which people can be happy. Some achieve it by adding zeroes to their bank account while some consider the lack of conflict in interpersonal - especially marital- relationships as a happy life. Whatever form it may assume, happiness can be achieved if a person is successful in his endeavor - whether
