Lost in the Desert Essay

Question 1. Given the conditions, what should Henry do to try to save Mark? He must decide very quickly. Mark has very little time left and may not survive the trip by helicopter to the hospital. What has caused Mark’s weakness, nausea, disorientation, headache, and low blood pressure? Why isn’t he sweating? Henry can do two things to immediately help Mark and his current physical condition. First, Henry should put clothing on Mark. Although Mark may feel very hot, his skin has already been exposed to the intense UV sunrays for an extended period of time. Continual exposure to these rays will worsen the severity of Mark’s sunburns. Henry should also start administering Mark diluted fluids that contain essential electrolytes, which to help restore hydration to Mark’s body without running the risk of his plasma becoming hypotonic from water intoxication. Mark has lost a lot of water through sweat and this combined with the intense heat of the sun has caused Mark to have heat stroke. The heat stroke and profound water loss is causing Mark to feel weak, nauseous, disoriented, have low blood pressure, and a headache. Water loss will especially have a large effect on Mark’s physical state because it will directly affect the blood pressure in his blood vessels due to water leaving the cells. Extreme water loss is also evident due to Mark’s lack of visible sweat. Hyperthermia has caused Mark’s heat loss process to become ineffective. In the extreme heat conditions, the heat stroke causes the skin to become hot and dry. Mark’s dehydration and heat stroke made it so that his body cannot produce sweat. (Mario) Question 2. Why didn’t the paramedic give Mark bottled water or distilled water rather than an electrolyte/glucose solution and what is an isotonic solution? In isotonic solutions, cells will be able to maintain their shape and size. This is due to the ability of water to move into and out of the cell when in this environment because the solution and solute concentration is at an equilibrium. The paramedic administered  Mark the electrolyte/glucose solution to help replace essential substances that Mark may have lost due to sweating or from being exposed to the harsh elements of the dessert. If Henry, the paramedic, were to give Mark a drink that was lacking the proper ratio of electrolytes/glucose to water, he could risk exposing the cells in the body to a hypotonic state, in which the cells would burst, or a hypertonic solution in which the cells would lose even more fluid. (Mario) Question 3. Why DID Mark become disoriented? How would you test your ideas to see if you are right? What does your group think based on the information in the text? Mark became disoriented because he was experiencing heat stroke. To see if I was right I would research the symptoms of heat stroke, and see if Mark had any of the symptoms. (Kassie) Question 4. What should Mark be concerned with regarding these moles? He talked to dermatologist, Dr. Charles Culp about the moles. What test might Dr.Culp conduct after removing the moles? Mark should be concerned that he has developed melanoma from his exposure to the sun without wearing sunscreen. If the dermatologist can tell for sure that the mole contains melanoma cells, special tests may be done to confirm their diagnosis. These tests that can be performed are called immunohistochemistry, fluorescence in situ hybridization, and comparative genomic hybridization. (Kassie) Final Set of Case Study Questions Question 1. Define the terms in the case study highlighted in boldface. Heat stroke is the condition in which the skin becomes hot and dry as the body temperature continues to rise. Damage may be done too many organs, such as the brain, due to the lack of blood flow. First-degree burn is a burn that affects only the superficial skin/first layer Electrolytes substance that ionizes in a water solution Glucose is a monosaccharide in blood that is the primary source of cellular energy Melanin is dark  pigment formed by cells called melanocytes (Kassie) Question 2. Assuming that Mark lost around 4 liters of water, what percentage of his body water did he lose? Would you expect his urinary volume to decrease or increase during his trek? Please explain your answer. If Mark, weighing 77 kg (average male weight), were to lose 4 liters of water that would be around 10% of his total body water. In his dehydrated and heat stroke state, Mark’s body would need to conserve water. I would expect Mark’s urinary volume to be decreased because he is dehydrated he isn’t in taking any liquid for him to be voiding out. (Vanessa) Question 3. Why was Mark’s blood pressure so low? Would his pulse rate decrease or increase? Also why was Mark dizzy and disoriented? Please explain. Mark’s blood pressure was really low because he was very dehydrated. Also because he is dehydrated and not in taking any fluids his blood pressure will continue to lower because there is no blood volume for his body to circulate his blood. Mark’s pulse rate will now increase, to try and raise his blood pressure to normal. Mark is dizzy and disoriented because he is dehydrated, and has a low blood pressure and pulse. Being severely dehydrated altered Mark’s brain and nerve function, making him feel very dizzy and disoriented. Also Mark’s low blood pressure and low pulse would make him feel dizzy because it is slowing the rate at which blood flows to his brain, lowering the levels of oxygen and making him feel light headed. (Vanessa) Question 4. Assume that Mark had an unopened six-pack of beer in his car. Would it have been a good idea for Mark to bring the beer along in case he got thirsty? Why or why not? Beer is known as a diuretic, which increases a person’s overall urine output. It would have been a bad idea for Mark to drink an unopened six-pack of beer for many reasons. Because beer isn’t water, it will eventually add to Mark’s dehydration by increasing his sodium levels and his urine output, both of which will make his cells in a furthered hypertonic state. This will also throw off Mark’s  electrolyte imbalance, adding to his cell’s hypertonic state. (Vanessa) Question 5. What vitamin would Mark have in greater amounts in his body after that day and what role does the vitamin play in the body? After spending an extended period of time in the sun, with no protection from the sun’s UV rays, Mark would have a great amount of vitamin D built up in his body. Vitamin D can be absorbed from dietary supplements or few foods, it is naturally produced when the sun’s UVB rays reacts with cholesterol. Vitamin D’s main role is to promote calcium absorption, as well as aid in bone growth and remodeling. Vitamin D also regulates cell growth, neuromuscular and immune function, and reduces inflammation. (La) Question 6. What did Mark do that increased his chance of burns and what could he have done differently? Mark took his shirt off as the heat intensity rose throughout the day. This exposed his unprotected skin to the sun’s harsh UVA and UVB rays. Not only was Mark not wearing any protection from the sun, but he also failed to wear sunscreen, which would have helped to shield his skin from the sun’s rays. If Mark had been wearing sunscreen or clothing to protect him from the sun, he may not have gotten such severe burns. (La) Question 7. Why would Mark’s skin have looked red within the first few hours of his adventure rather than redness developing hours and days later as a result of â€Å"sunburn†? Mark’s skin will appear red within the first few hours of his adventure rather than redness developing hours and days later as a result of sunburn because of blood in the dermal vessels adds color to the skin. When blood well oxygenated, the blood pigment hemoglobin is bright red, making the skin of light-complexioned people appear pinkish. (La) Works Cited Shier, David, Jackie Butler, and Ricki Lewis.

Intern - Essay Example All in all, I think this was a good week. The next week, life as an intern was both easier and harder to manage at the same time. It was easier because by this week I already had a better feel of my working environment. On the other hand, it was also harder because now I am feeling the load of work of a corporate manager. Of course I knew from the start that at this line of work juggling more than one task at a time is part of the job description. I realized important it is to keep my focus and keep things organized. To make sure that things run as smoothly as possible, I devised a simple strategy: that is making a weekly schedule of my tasks and duties, spreading out my tasks in those days and setting a completion target every day. Because as much as I want to accomplish everything in 24 hours, I cannot, I found early on that this is quite difficult to manage. Thus, the system, it helps me focus and keeps me from being overwhelmed from the load of my responsibilities. By my third week, I hate to admit but I was starting to feel the stress. And I just kept thinking to myself that I cannot let stress get the better of me. I knew that it does not only affect me but my co-workers as well, such negative energy could create a domino effect. I was trying my best not to take my stress out on my co-workers and cause a stress on our working relationship, I want to earn their respect and be respected as well so I had to do something to control the matter.

Domestic Terrorism Master Essay Example | Topics and Well Written Essays - 2750 words

Domestic Terrorism Master - Essay Example Both domestic and international terror groups have the same enemies both terrorists group enemy is the government as these terrorist groups usually consist of the oppressed class, and this class feels that it is the government's fault that they do not get their fair share. Thus the government is the common enemy of both the terrorist groups. A good example of domestic terrorism is that Various recent events, most particularly the bombing of the Federal Building in Oklahoma City, Oklahoma in April, 1995, thus proving the fact that Organized extremist/terrorist groups of particular concern with regard to their abilities to recruit from, and exist within the United States armed services have historically been racist and/or anti-government in character. (http://www.fas.org/irp/eprint/presley.htm) Terrorist have started to use the in two ways. The First and most common way is that, the Internet has developed into a forum through which both terrorist groups and individual terrorists can spread their intense and influential messages of hate and violence far and wide. Through this fast developing forum they can also communicate with one another and with those who show sympathy towards them. The Second way in which terrorist use the internet for their terrorism is that, individuals as well as groups have attempted to make an attack on a lot of computer networks, as well as those on the Internet this is called cyber terrorism or cyber warfare. At present, terrorists proffer to use the Internet for their purposes more than they are attacking it. At least twelve of the thirty groups on the State Department's list of selected foreign terrorist organizations keep Web sites on the Internet. Whereas U.S. officials strongly believe that a number of terrorists use encrypted E-mail to plan their evil acts of terrorism, the majority of groups seem to use the Internet so that they can spread their propaganda all around the world. Good number Internet sites of terrorist groups seek to promote the organization's political and ideological agenda. A good example is of this is that directly after the Peruvian terrorist group Tupac Amaru broke into the Japan's Ambassador's residence which was in Lima as well as apprehended scores of diplomatic, political and military officials hostage in December 1996, sympathizers of Tupac Amaru in who were citizens of U.S. and Canada developed quite a lot of solidarity Internet sites, one of the sites even had comprehensive drawings of the terrorists' plan of assault on the residence of the Japanese Ambassador's. When most of the free and English speaking world thinks of the word enemy, a warrior dressed assassin or foreign solder from a communist country usually comes to mind. Enlisted soldiers, sailors, airmen and marines who fight tirelessly to defend our country see the enemy as that exactly. Unfortunately, there is a new enemy threatening our way of life. This enemy attacks through e-mail messages and internet connections.

The Tesco Management - Essay Example â€Å"Tesco started life in 1919 when Jack Cohen started selling surplus groceries from a stall in the East End of London.

E Stockwell. The year 1929 marked the opening of a store in North London and the company rapidly developed from there on. The head quarters of the company was first established in North London in the 1930s. In the year 1932 the company became a private limited company, another feather in the cap of Tesco.Expansion of the CompanyThe expansion of the company traces back to the year 1950 when the company quickly bought rival shops so as to expand and compete with other Giants.

Just summary article - Essay Example Another problem that is presented in the article is perceived discrimination or prejudice. Taiwanese students are said to be the ones greatly suffering from this perception. Moreover, the length of stay again has an effect on this issue. As the students stay longer in the country, they come to learn more about the language and therefore their perceived discrimination lessens as they communicate more with Americans and know more about their American ways. Lastly, homesickness is seen as one adjustment issue that foreign students face. Research studies show that American freshmen showed lesser signs of homesickness compared to foreign students and this is affecting their social activities as well as their coping with the demands of college life, not to mention a new life in a new country. As the researcher proceeded with the study, it was found out that there are things that need to be considered for further studies such as the subjects. Most of the studies used in the article included undergraduate and graduate students. The concern of the author is for a study to be concentrated more on undergraduate students for a comparison if there is a correlation of the issues mentioned above with the age of students. de Arajao, Abrahao Andre.

Journal of Consumer , the Journal of Marketing , or the Journal of Consumer Psychology - Research Paper Example In this experiment, forty university students were used as the participants. The results demonstrated that the participants viewed the brand more positively when a fee is not charged. In the second experiment, the author aimed at understanding how people react to comparable and non-comparable rewards offered back by the brands. In this study, ninety four undergraduate students from a university in North America took part. The results showed that exchange oriented consumers expect comparable benefits from the brand partners. For communal consumers or partners, benefits that are not necessarily comparable but recognize their efforts are accepted. Finally, the author undertook an experiment to examine how the time taken between seeking help and offering of help affects consumer behavior. Ninety five students took part in the study. Results showed that consumers view brands negatively if there is a delay in the return favor request. Overall, the behavior of the participants in the three scenarios demonstrated that consumers’ behavior and attitudes is greatly influenced by the actions of the brands. The use of human subjects allowed for an actual observation of the attitudes and behavior of the participants towards the brands, thereby providing an insight into consumer behavior. The present research, conducted by Anat Keinan and Ran Kivetz (2008), aimed at evaluating the effect of anticipating long term regret in consumer behavior. The authors argue that anticipating long term regret has an effect on consumer preferences and may motivate them to counteract their virtues or good tendencies and engage in virtues. In order to test this hypothesis, the authors used three sets of participants in three different studies. In the first study, the authors asked participants to examine and judge the regrets of others relating to a past decision and then come up with a choice for themselves. 91 train station travelers participated in the study.
