Acute vs Chronic abdominal pain - Essay Example As result, they experience acute abdominal pain. Diverticulitis is another common cause of acute pain among people in this age group. This is a condition whereby pouches develop on the walls of the colon. Older patients also experience bowel obstruction that may result from cancerous cells (Lyon & Clark, 2006). Common causes of acute abdominal pain in a 20-year -olds male may be due to indigestion, stomach irritation, and parasitic infections. Chronic abdominal pain in a 50-year-old male can be caused by colon cancer, gallstones or appendicitis. In a younger patient, chronic pain can be caused by pancreatitis, cholecystitis, hepatitis and liver disorder (Greenberger, 2014). In reference to diagnosis, it is more likely to misdiagnose a 50-year-old as compared to a 20-year-old. This is because older patients are prone to other co-existing diseases that may be the hidden cause of abdominal pain (Bryan, 2015). As compared to younger patients, diagnosis in older patients does not rely on symptoms such as fever, nausea and vomiting (Tazkarji, 2008). This is because most of them do not exhibit these symptoms. Older adults also present late symptoms. All in all, both young and old patients require specialized treatment (Penner, 2015). Greenberger, N. J. (2014). Chronic and Recurring Abdominal Pain.

Our Hands Essay There is great societal influence on the family builders, the parents, as to their preference, bias toward the number and sex of children. As a result of this societal influence, the effects are apparent. One effect is that if two parents have two children, one of each gender, then a third is not very plausible. If a family has two children both of the same sex, then they are more apt to have a third. A second effect of this societal influence pertains to China and its One-Child Policy. The effect is detrimental to its female population. An obvious result to such influence is a climb in the number of worldwide abortions, and infanticide. There is a new product on the market and available to the world right now that will aid society in its persuasion and this product is the Baby Gender Mentor(tm) Home DNA Gender Testing Kit. This product will have a grave significant effect on the future outcome of global society both economically and ethically. The responsibility is too great to be left in the hands of the individual and must be monitored by the governments. Family sex structuring has occurred since the beginning of the studies and surveys that date back to 1915. Family sex structuring is the planning with intentions directed toward the preference of one sex over another. This preference is only one theory involved in the reasoning of the article Emerging Parental Gender Indifference? Sex Composition of Children and the Third Birth by Michael S. Pollard and S. Philip Morgan. The original in depth idea of the article is that a family consisting of two parents and two existing children, each of the same sex, will statistically be more likely to add a third child in the hope of having a child of the opposite sex than the preexisting two. Families consisting of two parents and two children of opposite sexes are statistically less likely to add a third. This article introduces studies and theories trying to answer the reasoning for and against this idea. One theory is that this idea of family sex structuring is becoming progressively less and less important since 1995 up to the present, the current shifts in the gender system. The current shift in the gender system is due to the acceptance of women and they getting higher education and powerful positions. Roles have changed for women immeasurably in the last fifty years. Girls were encouraged to knit, sew, embroider or weave. While these activities were necessary tasks for females in the past, they are less necessary now and leave women to accomplish greater feats. Todays women may choose, and are encouraged and supported, to attend college. They are able to go places on their own and are not weighted down by as many responsibilities of the household as they once were. Some responsibilities are still expected, but men are also expected to pitch in and help with housework. Also, women from all classes are also able to mingle freely with other classes and the opposite sex without fear of a diminished reputation. Men are much less threatened at the idea of women holding powerful, commanding positions because women have proven equality of the sexes. Equally well, women can roam the Internet, support themselves financially and pay the bills, root for a favorite baseball team, or even if fact, play on a baseball team. Many women have chosen to include sports and fitness routines among their lifestyle choices, recognizing the physical and mental health benefits of exercise. Women have struggled to earn independence and respect, and have succeeded. Women since the seventies now have a choice to terminate their pregnancy if they feel that a child will interfere with their lifestyle of simply, if they so choose.

My Antonia Essay: Theme of Separation -- My Antonia Essays

Theme of Separation in My Antonia    My Antonia, by Willa Cather, is a book tracing the story of a young man, Jim Burden, and his relationship with a young woman, Antonia Shimerda. Jim narrates the entire story in first person, relating accounts and memories of his childhood with Antonia. He traces his journey to the Nebraska where he and Antonia meet and grow up. Jim looks back on all of his childhood scenes with Antonia with nearly heartbreaking nostalgia. My Antonia, is a book that makes many parallels to the sadness and frailty, but also the quiet beauty in life, and leaves the reader with a sense of profound sorrow. One of the main ways Cather is able to invoke these emotions in the reader is through the ongoing theme of separation. Willa Cather develops her theme of separation through death, the changing seasons, characters leaving and the process of growing apart.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Cather sets the tone of the story at the very beginning; a young Jim Burden's parents have died leaving him to go to Nebraska to live with his grandparents. Right from the start Cather plants the seeds of abandonment, with the finality of death, in Jim's life. When he arrives in Nebraska he is very numb to life, but he is soon caught up in daily life on his grandparents' farm. He is blissfully happy when he first meets Antonia. They become great friends and share numerous adventures. Cather uses brief, beautifully descriptive and nostalgic recollections of situations and feelings to increase the pain and sadness of the separations that she places throughout the book. An excellent example of this is the way Cather builds up to Mr. Shimerda's suicide.      Mrs. Cath... ...      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Mrs. Cather's carefully drawn parallels in the story that build up to Antonia and Jim's separation was a truly effective method of pointing out its tragedy. However she also used other tools, such as imagery and short anecdotes to further convey her message. All together these elements, plus a good story and plot make My Antonia an excellent all around book, worthy of being called a classic.    Professors Comments: Underline titles of novels. Using quotes from the book would strengthen your paper. Quotes prove to the reader that you have a valid argument. You discuss imagery in your paper to prove certain points about the separation theme. Direct quotes would have been useful.   You attempt to discuss parallelism only on one occasion. This discussion should be expanded.

Dreaming of Time Travel Essay

The reading â€Å"Dreaming of Time Travel† discusses applications of time machine, whether time travel is possible and how time travel can be explained in terms of physics and quantum mechanics. The author highlights such issues as meeting yourself in the past, time as fourth dimension, many-world theory, self-consistency, concepts of wormhole and star trek. It is a matter of fact that human imagination has been always captured by opportunities of time travel as it would give an excellent opportunity to see own past and perspectives for future. Science is interested in time travels the most as it would help to solve historical and scientific conflicts and controversial points. Of course, if people had time machine, they would definitely visit twenty-third century to look for technological advances and to find effective ways of cancer treatment. Nevertheless, time travels may change the past and, consequently, future would be changed as well. You may seven slip out of existence as a result of change. It would be possible to kill Hitler preventing, in such a way, World War II and save millions of innocent deaths. People would be able to participate in historical events shaping them. Moreover, it would be possible to meet historical figures as, for example, Buddha, Moses, Cleopatra or Shakespeare. Actually, there is no limitation of possibilities. Time travel makes people feel free to move around the world, but they may be helpless as they are not acquainted with cosmic order. Nowadays the issue of time travel has become a matter of interest for physicists, not only for fiction writers. For example, when Wells wrote his famous â€Å"The time Machine† many believed that it was impossible to travel through time and space. It is Einstein’s Universe that makes time travel possible and understandable. Therefore, many physicists are actively investigation time travel to the past. In his ideas Einstein uses the concept of time as fourth dimension. This idea is used to show that time can be measured by moving and stationary observers. Therefore, Einstein argues that our universe is four-dimensional. The idea of many-world theory is also very interesting as it offers radical alternative of viewing our world. Many-world theory is based primarily on quantum mechanics developed in the beginning of the 20th century. Quantum mechanics was used to explain the behavior of molecules, atoms and other micro-particles. Quantum mechanics proved that particles had wave nature. It is assumed that people won’t change the pass if they travel because they are a part of it. However, Einstein viewed it as paradox. Therefore, the concept of self-consistency was introduced to explain the possibility of historical changes. It seems that self-consistency is rather controversial to the common sense of free choice and free will. Therefore, time travelers are likely to be constrained being deprived of essential human ability. For example, David Lewis argues that free will never allows people to do logically impossible things. Four-dimensional world doesn’t change as it is viewed as fixed sculpture. Time-travel stories are also based on self-consistency system. In time travel the particles have world line meaning that there is a circle with no ends. Such particles are called jinn. They are claimed to arrive by wizardry as in Aladdin’s story. Often fiction literature involves scientific investigation of time travel. For example, â€Å"Star Trek† fiction encourages further time-travel investigation from scientific perspective. It stresses that it is possible to use warp-drive to ravel in past. Fiction often stimulates scientific thinking. Physicists are the most interested in time travel as they want to test the boundaries and opportunities of physical laws, as well as to patent a time machine. The author concludes that time travel seems so strange for people simple because they aren’t accustomed to meet time travelers in our everyday life. If people meet them everyday, they won’t be surprised. If time travel can occur in principle, scientists will receive new insights about the universal order. Works Cited Gott, J. Richard.

God and chases ambition blindly Essay

   And afterward, he runs away from society in the attempt to rid himself of the monster. This shaky groundwork sets up traumatic loss to come, as Frankenstein does not realise that his family will not be there for him in the end, when he is lonely and in need of their company. Although he is successful in creating life, one of Frankenstein’s greatest flaws in his attempt to create a being, is that he does not even nurture it as a parent would for his own child. Frankenstein decides that he doesn’t like the monster after he has finished it. He rejects the monster, and in turn the monster rejects him. In the end, the monster reflects upon his own state of affairs: â€Å"my heart was fashioned to be susceptible of love and sympathy; and, when wrenched by misery to vice and hatred, it did not endure the violence of the change without torture, such as you cannot even imagine. † The monster has been treated as subhuman, as a â€Å"thing† that does not deserve love or affection. Frankenstein declares, in agony over his creation, â€Å"Oh! No mortal could support the horror of that countenance. A mummy again endued with animation could not be so hideous as that wretch. † Frankenstein feels that he has created something completely revolting, and he rejects his own creation. He wants nothing to do with the monster, let alone receive honours for his creation. And after all Frankenstein does to achieve his goal, the monster becomes a curse to Frankenstein and his family. Out of Frankenstein’s originally â€Å"glorious† creation comes gruesome and disastrous results: the monster becomes so rebellious due to the fact that Frankenstein and all of society shuns him, that the he kills nearly all of Frankenstein’s family one by one. â€Å"I have murdered the lovely and the helpless; I have strangled the innocent as they slept and grasped to death his throat who never injured me or any other living thing. I have devoted my creator, the select specimen of all that is worthy of love and admiration among men, to misery. † Earlier in the novel, we are introduced to Walton, a sailor on a boat destined for the arctic seas. Walton has something in common with Victor Frankenstein: ambition to achieve something that no man has ever accomplished before. Walton wants to sail to the arctic because no sailor has ever reached it. However, the difference between Frankenstein and Walton is that Frankenstein achieves his goal, with terrible consequences. But unlike Frankenstein, Walton decides to turn back before reaching his desired destination. At the end of the novel the ship abandons the initial driving ambition to be the first to sail to the arctic. Walton decides to go with them, because that is the will of the entire ship and he decides to choose community instead of isolating himself for his own personal conquest. Walton realises, from Frankenstein’s mistakes, that sometimes it is better to make choices based on the common good of all involved, instead of blindly chasing a dream that excludes other human beings and disregards thought to the ultimate welfare of society. Ultimately even Frankenstein, on his deathbed, realises the truth of the consequences of his actions. He says, â€Å"Seek happiness in tranquillity, and avoid ambition, even if it be only the apparently innocent one of distinguishing yourself in science and discoveries. † To be at peace with one’s own mortality is essential to living a full and rich human life. Frankenstein’s mistake was that he wanted to be the first man to achieve something which no man had ever done before his time; to rise above human achievement, to rob the sacred act of creation and bypass this natural gift given to humanity by using scientific means. These actions all caused others to suffer and to ultimately die for Frankenstein’s own prestige. Mary Shelley’s Frankenstein shows that dabbling with the work of God or nature is immoral and ethically corrupt. Trying to play God is not the responsibility of mortals. This novel also shows that a person who chases notoriety purely for his or her own personal gain may find the consequences of their actions to be truly devastating. In her protagonist Shelley explored in detail many of the implications of involvement in research, thereby providing the details which have been subsumed in the complex mythology of the inhuman scientist – the psychological effects of isolation and suppression of human affections, loss of the ability to appreciate natural beauty, the naive optimism that knowledge will inevitably be for the good of all, the fanatical desire to complete a project whatever the human cost.

Chickenomics essays

Chickenomics essays Chickenomics is a short twenty minute instructional video tape on the basics in economics. The video tape uses an original man in a chicken suit idea to explain economics. The five basic characteristics of economics are explained in an easy and simple way using the Chicken. This video tape is a great way to teach the basics of economics. The video starts off by introducing the chicken. The chicken is originally a man in a chicken suit who works for a Los Angelus radio station. The Chicken -as he is referred to in the video- now also works as a Mascot for a baseball team. To show some of the basic concepts of economics a question is asked why is this chicken in 250 million born every year so successful? The five basic characteristics of a Market Economy are introduced to answer that question. The first is that a market economy has private ownership of resources. This means that labor and other types of resources are government protested ownerships. In the video it is explained that the Chicken or the man in the chicken suit is a rare individual who has the skill of entertaining people. The second characteristic of a market economy is Self interest motives. This means that each person is free to pursue whatever job or position in the market he desires.*** The third characteristic of a Market economy is consum er sovereignty. This means that the market is controlled by consumers and that only the products that the consumers want are produced.*** The fourth concept in a Market Economy is that it is a market. The Market Economy being a market means that everywhere a transaction is made or every where a product or service is bought or offered.*** The last characteristic of a Market Economy is Competition. Competition is other people or companies offering the same product. To explain why this is such a good thing in the economy the video uses the example of the Chicken sellin ...

Sampling With or Without Replacement

Sampling With or Without Replacement Statistical sampling can be done in a number of different ways. In addition to the type of sampling method that we use, there is another question relating to what specifically happens to an individual that we have randomly selected.   This question that arises when sampling is, After we select an individual and record the measurement of attribute were studying, what do we do with the individual? There are two options: We can replace the individual back into the pool that we are sampling from.We can choose to not replace the individual.   We can very easily see that these lead to two different situations.    In the first option, replacement leaves open the possibility that the individual is randomly chosen a second time.   For the second option, if we are working without replacement, then it is impossible to pick the same person twice.   We will see that this difference will affect the calculation of probabilities related to these samples. Effect on Probabilities To see how we handle replacement affects the calculation of probabilities, consider the following example question. What is the probability of drawing two aces from a standard deck of cards? This question is ambiguous.   What happens once we draw the first card?   Do we put it back into the deck, or do we leave it out?   We start with calculating the probability with replacement.   There are four aces and 52 cards total, so the probability of drawing one ace is 4/52. If we replace this card and draw again, then the probability is again 4/52. These events are independent, so we multiply the probabilities (4/52) x (4/52) 1/169, or approximately 0.592%. Now we will compare this to the same situation, with the exception that we do not replace the cards.   The probability of drawing an ace on the first draw is still 4/52. For the second card, we assume that an ace has been already drawn.   We must now calculate a conditional probability.   In other words, we need to know what the probability of drawing a second ace, given that the first card is also an ace. There are now three aces remaining out of a total of 51 cards. So the conditional probability of a second ace after drawing an ace is 3/51.   The probability of drawing two aces without replacement is (4/52) x (3/51) 1/221, or about 0.425%. We see directly from the problem above that what we choose to do with replacement has bearing on the values of probabilities.   It can significantly change these values. Population Sizes There are some situations where sampling with or without replacement does not substantially change any probabilities.   Suppose that we are randomly choosing two people from a city with a population of 50,000, of which 30,000 of these people are female. If we sample with replacement, then the probability of choosing a female on the first selection is given by 30000/50000 60%.   The probability of a female on the second selection is still 60%.   The probability of both people being female is 0.6 x 0.6 0.36. If we sample without replacement then the first probability is unaffected.   The second probability is now 29999/49999 0.5999919998..., which is extremely close to 60%.   The probability that both are female is 0.6 x 0.5999919998 0.359995. The probabilities are technically different, however, they are close enough to be nearly indistinguishable.   For this reason, many times even though we sample without replacement, we treat the selection of each individual as if they are independent of the other individuals in the sample. Other Applications There are other instances where we need to consider whether to sample with or without replacement. On example of this is bootstrapping. This statistical technique falls under the heading of a resampling technique. In bootstrapping we start with a statistical sample of a population. We then use computer software to compute bootstrap samples. In other words, the computer resamples with replacement from the initial sample.
