Difference Between America and South Korea Health Care Essay

Each country has a different procedure when it comes to their health care and their care with pre and postnatal. Some countries can spend a great amount of money on their health care (such as the United States) but still might not have the best health care in the world. Others have special arrangements that new mothers and infants can go through to make sure that they start off their life in a good and healthy environment. In this paper I am going to compare and contrast the infant health care and the overall prenatal care in the United States and South Korea by referencing multiple articles and textbooks that focus on this subject. Both countries have various ways in which they handle their health system and the care of their newborns. There are many factors that determine the health of a newborn such as the nutrition that the soon to be mother consumes, the environment that the mother and the child live in, and the hospital that the child is born in. Throughout the years each of these countries have been putting time and money into their health system with the goal of having the most outstanding health care system in the world. Their progress can be recorded in many different ways which will be discussed within this paper. Also the United States and South Korea both have very different systems when dealing with prenatal and infant care. One way that the infant care of a country is measured is through the mortality rate of the infants. In fact (Bae et al. , 2011), â€Å"Neonatal mortality rate (NMR) and infant mortality rate (IMR) are two of the most important indices reflecting the level of public health of a country† (Abstract Section Para. 1). Without measuring and keeping track of these mortality rates, researches would not be able to figure out what countries are working towards a better health care service and which countries need help. Even though the United States is a developed country, and unlike less developed countries, it should have a high mortality rate. In all actuality the United States has one of the worst mortality rates compared to other counties. According to Levine and Munsch (2012), â€Å"Despite the wealth and the availability of (but not always access to) world-class edical facilities, the United States has the same or worse infant mortality rates compared with 37 other industrialized countries (Hoover Institution, 2007)† (p. 176). There are reasons for the high mortality rate, such as the fact there are many different races, ethnicities, and social statuses within the United States. Race and ethnicity do have an input in a person’s health and their life style. Some races (such as Asians) have a higher life expectancy and a lower mortality rate throughout their race because of the way that they are raised and the traditions that they fallow. The social statuses of the expecting mothers also have an impact on the future children because when the parent is part of a higher social status, it is assumed that they have a higher level of education and therefore know more about how they should care for themselves and their infants. The opposite goes for people who are part of a lower social status. The United States has been lowering the number of infant mortality rates by putting programs in affect to try and help out the health system. Some of these programs are (Bae et al. , 2011), †¦execution of Medicaid (1965), Medicare (1965), Supplemental Security Income (social health care security programs for children and pregnant women of the lower income group), provision of State Children’s Health Insurance Programs, Children Vaccine Program, Health Start Program (1991, Early Head Start Program, full day care service, parent education, case management, Community Resource Assistant)†¦Ã¢â‚¬  (Discussion Section para. ) and much more. The United States has more programs to help reduce the risk of infant mortality and various diseases, they are also working on other ways to help out the infant mortality rate by focusing on premature and low-birth weight babies. According to Levine and Munsch (2012), â€Å"Birth data compiled by the Centers for Disease Control and Prevention (2007a) for 2005 found that the rate of premature births in the United States is 12. 7% or 525,000 babies annually† (p. 178). This number is high for premature births and these programs that are being put into place should help lower it. Even with all of these programs working toward a better health system, South Korea has less of an infant mortality rate. South Korea has improved its health system throughout the years and it has shown in their child care. Their country includes programs such as (Bae et al. , 2011), †¦tests for inborn error of metabolism and care for sick infants (1991), registration of pre-term and congenital abnormal neonates and medical expense support 2000), early diagnosis of deafness (2007), campaign for preventing blindness of preschoolers (2000), prevention of maternal hepatitis B infection (2002†¦(Discussion Section Para. 1) and much more. There are also more programs that are scheduled to appear throughout the fallowing years. As mentioned before it is easier for South Korea to keep their infant mortality rate down because they do not have to focus on many different nati onalities in their country, most of the population in South Korea are Korean. If you compare the two countries and the programs that they are producing it is shown the South Korea has been receiving more advances in the 2000’s while the United States had a breakthrough in their health care in the 1900’s. Copyright  © 2011 The Korean Academy of Medical Sciences. This chart shows that South Korea started off with a higher mortality rate and it had a drastic decline. The United States had a decline in the 1900’s and during the 2000’s it started to stabilize. Copyright  © 2011 The Korean Academy of Medical Sciences. This Chart gives a better understanding as to where the United States and South Korea stand with other countries. Neither of them are the best or the worst country, however they are on opposite sides of the scale. It is expected for the United States to have a lower mortality rate because of the amount of money put into their health care system, but according to the chart this does not appear to be true. South Korea has a lot of respect when it comes to their infants. They see their children as the future to their country and they are willing to do anything to make sure that their infants are well taken care of. This is shown through the data on the chart above because South Korea is closer to the bottom of the scale instead of the top. Both South Korea and the United States have a different hospital system. South Korea has a post-natal care facility called a sanhujoriwon. According to Yeon-soo (2013), Dozens of mothers and newborns stay together in such facilities and more than half of the places operate as non-medical institutions, leading to occasional problems with hygienic management. To prevent mass infection among babies at sanhujoriwons, the government recently beefed up disease surveillance of workers there and instituted a standard terms of use (Para. 2) South Korea is the only country that has these facilities available for their new mothers. Many pregnant women from all over the world come to South Korea just to get this treatment after they give birth. However, this facility is expensive, so not everyone can afford this luxury. According to Yeon-soo (2013), â€Å"The cost of using an upscale sanhujoriwon is 5 million (4,730 U.  S. dollars) to 10 million won (9,460 dollars) for a two-week stay, but the facility is so popular that a reservation might not be possible if not made six to seven months prior to childbirth† (para. 4). That is the price for the most expensive and luxurious places; other places can be thousands of dollars cheaper. In these facilities the nurses make sure that the patients get the right exercise (such as light yoga) and eat the correct food so that their recovery after birth will be as pleasant and beneficial as possible. They also care for the newborn and make sure that they get the nutrients that they need in the first couple of weeks. This helps out the new mother because they have time to relax and recover while their baby is getting the necessary care that is needed. When the mother is ready to go home after a couple of weeks they have a better time adjusting to their new life with a baby because they had the rest and help that they needed. In the United States they do not have these same accommodations but they to do have systems to help out the new mother. The United States has many medical professionals to help with neonatal and postnatal care. Some of those occupations include (Link, Jakubeez, & Temple, 2013), â€Å"†¦neonatologist, neonatal nurse practitioners, bedside nurses, a clinical pharmacist, neonatal respiratory therapists, a nutritionist, a social worker, medical residents, and medical students† (Backgroud Section Para. 1). With a hospital consisting of these medical professionals the patients are likely to get the help that they need while going through the birthing process. Also many hospitals are expanding in the United States to include more room for neonatal care. The Hillcrest Hospital in Cleveland, Ohio expanded their hospital and included (Link, Jakubeez, & Temple, 2013),†¦Ã¢â‚¬ a new 24 bed level 3 neonatal intensive care unit (NICU) and additional beds to accommodate high-risk maternal medicine patients† (Background Section para. 1). They expanded their hospital so that they could care for more patients at once; also so that the patients got the opportunity to receive the best care available to them. Usually after a mother gives birth (depending on the birthing method), the mother will stay at the hospital for a couple of days, and then return home. While at the hospital the nurses will help the mother with nursing, feeding, and changing the child. They will also make sure that the mother is recovering well after the birthing process. Both in the United States and in South Korea, they have programs to help mothers and infants after birth. However, the system in South Korea is more advanced because it keeps the mother and infants for a longer period of time which is more beneficial to their health. Nutrition to a pregnant women is a very important factor. If the mother does not get the correct nutrition than they are putting themselves at risks for multiple diseases. Also they are not only putting themselves at risk but they are also putting their unborn baby at risk. Some diseases that the mother can catch from bad nutrition are gestational diabetes, gestational hyptertension, and preeclampsia. Gestational diabetes when not looked after turns into gestational hyptertension; the worst out of the three that were mentioned is preeclampsia. This is because (Sizer & Whitney, 2011), â€Å"Preeclampsia affects almost all of the mother’s organs—the circulatory system, liver, kidneys, and brain† (p. 508). If all of these organs are affected than the baby is at a serious risk of getting hurt. Most of these diseases will disappear after giving birth, but it raises the risk for the mother to catch another serious disease, such as type two diabetes. When a pregnant women is diagnosed with having gestational diabetes they are more likely to catch type two diabetes later on in life. It might not be right away but it could happen a couple of years later. Also they are more likely to be diagnosed with gestational diabetes again if they ever become pregnant again. Being overweight and pregnant is a big risk during pregnancy. In fact (Chen et al. , 2013), â€Å"Metabolic impairments in maternal obesity and gestational diabetes (GDM) induce an abnormal environment in peripheral blood and cause vascular structure alterations which affect the placental development and function† (Abstract section Para. 1). As mentioned before it does not only affect the mother but it also affects the unborn child, but it also affects the child after they are born. Using APA, 2013), â€Å"The historical poor outcomes of pre-gestational diabetes are testimony to the harmful effects of high glucose in early pregnancy as manifest by congenital malformations and in later pregnancy as evidenced by LGA [large-for-gestational-age] and its consequences. † (para. 2). The reason why this is more of a problem in the United States is because they have a higher obesity record than South Korea has. So more women throughout the United States are developing these diseases than women in South Korea. (Amamoto et al. 005) â€Å"Comparison of body mass index (BMI) distributions in Japan and Korea showed the highest value in the normal category (74%) together with a very low obesity rate (1. 2%)† (Results section para. 1). Since South Korea has a low obesity rate within their, they are less likely to give birth to large babies. However, the opposite goes for Women who live in the United States and are obese. This is a problem because (Sizer & Whitney, 2011), â€Å"The infant of an obese mother may be larger than normal and may be large even if born prematurely. The large early baby may not be recognized as premature and thus may not receive the special medical care required† (p. 492). A premature baby might not be completely developed and need medical assistance after the birth. If the doctors don’t know that the baby has developmental problems than the newborn runs the risk of dying. This could also explained for the high mortality rate in the United States since they have a higher rate of obesity and it is difficult to label a child as premature and unhealthy if they are at a healthy weight. The environment that the pregnant women is living in is very crucial to her and her unborn child’s health. There are many illnesses that a woman can pass on to her child from environments that are hazards. When a mother is in her embryonic stage her baby is at a point of rapid development. This is a very crucial stage because the baby is starting to grow their organs, however they are also more likely to catch a disease which could cause a deformity during this stage. If the mother catches a disease than they are more likely during this stage to pass it to their baby which could cause a miscarriage or deformities. The issue of the environment is more of a problem for South Korea because of all the pollution that is in the air. South Korea is a very overpopulated country (especially in Seoul) and with all the cars and factories the air gets easily polluted. According to Sizer and Whitney (2011), â€Å"Pregnant women who are exposed to contaminants such as lead often bear low-birthweight infants with delayed mental and psychomotor developments† (p. 04). This is also an issue in some part of the United States, but it depends on where the person lives. If a pregnant women lives next to a factory that produces hazardous smoke than they are more likely to give birth to a baby with deformities. However, in South Korea many pregnant women are exposed to polluted air for most of their pregnancy and some of their babies are born with serious skin pro blems. There is air pollution everywhere a pregnant women goes but if the pollution is high than they are putting the baby more at risk. There are many factors that play into the prenatal and postnatal health. South Korea and the United States both work hard to make their health system the best that it can be. They have many programs in place and many more programs to come in the future. They are working on their hospitals to make sure they are as convenient as possible so that the mothers and newborns can have the best possible health care. Both countries are working towards lowering their mortality rate and lessening the amount of premature and low-birth-weight children. There is also the nutrition and the environment that the mother is exposed too. A simple factor as being obese can cause serious damage to the mother and the unborn child. Many expecting mothers do not understand that concept so they do not see the risk in it. Of course one country has a better health care system then the other, however they both have pros and cons to their countries. The United States has more funds to deal with and has more medical professionals working in their hospitals so that their patients can receive the best care possible. The negative aspect of the United States is that they have a high obesity rate and a high mortality rate. They also need to work on more programs to lower their mortality rate so that they can have the best possible health care. South Korea has excellent postnatal care, which many people around the world want to experience and be a part of. Also they have a low level of obesity so they are not as likely as the United States to get the diseases that come along with being overweight. The negative aspect of Korea is that their environment is not the best because of the pollution that is surrounding the air. South Korea is an overpopulated country so the air is filled with pollutants that are not good for a pregnant woman and can cause low-birth weight and birth defects. Overall both countries have areas in their health care system that they have to work on and areas outside of their health care system that they need to address. However, as of right now South Korea has a more exceptional health care system than the United States, especially when it comes to infant care.

Types of Reinforcement

People have been using the theory of reinforcement even though they have not properly studied this theoretical concept. They have been employing this theory to strengthen the response for a particular stimulus or environmental event (Huitt and Hummel). Reinforcement theory generally states that the frequency of eliciting the same response will likely increase if it is followed by a reinforcer. The probability of repeating the same behavior in the future is dependent on what occurs after the individual engages in that behavior (Malala, et al. ). There are four types of reinforcement.Each type of reinforcement is distinguished by the kind of stimulus presented after the response. In positive reinforcement, for instance, a positive stimulus is presented after a certain response to increase the frequency of that response of behavior (Malala, et al. ,; Huitt and Hummel). The positive stimulus usually comes in the form of rewards. Positive reinforcement has been used in school settings to reinforce positive attitude towards studying. For example, academic awards such as medals and certificates are given to students who excel academically or in a certain field such as sports.While the previous example used a tangible positive reinforcer, it could also be intangible. To cite an example, according to Kobus and her associates (48), the praise, support, and encouragement of teachers and significant others (e. g. , parents) motivate grade school students to work hard and increase their self-efficacy (i. e, confidence in one’s capability). Positive reinforcement has often been used by parents as well. They reward their children with a reinforcer such as money for their hard work in school or for cleaning their room.The concept has also been applied by companies for their employees. Salary increase and promotion, for example, are awarded to hardworking employees for their outstanding performance. On the other hand, in negative reinforcement, the reinforcer, which is s omething negative, is withdrawn after the response. Repetition of this phenomenon will increase the occurrence of the response. This is usually observed when a person wants to avoid the negative reinforcer (Huitt and Hummel). For instance, children obey the house rules so that their parents will not get mad at them.In this example, the negative reinforcer is the anger of the parents while the response is the obedience of children. At work, employees meet their requirements and deadlines to avoid being reprimanded by their boss. Most people think that negative reinforcement and punishment is the same, which is a misconception. While negative reinforcement elicits a positive response due to the removal of the negative reinforcer after the response, punishment lessens the frequency of a response or behavior by presenting a negative stimulus after the response (Huitt and Hummel).Punishment has been used at home, in school, and in the workplace. For example, at home, parents ground their children when they do not come home at the time agreed. In school, punishment is imposed to discipline students. A simple example of this is reprimanding noisy students for disrupting the class. Punishment has been a system adopted in schools in the form of disciplinary policies where punishment for specific types of school offense are indicated (Gaustad 3). In the workplace, an example of punishment could be reducing the salary of employees when they do not report to the office without filing a leave.As punishment, they will not be paid for the days they did not come to work. The fourth type of reinforcement is extinction. In extinction, the frequency of a response or behavior is weakened when the reinforcement of a previously reinforced behavior is removed (Huitt and Hummel). To cite an example, in the field of psychology, extinction learning has been used in treating disorders such as anxiety disorder. The goal of the treatment is to extinguish fear by teaching the patients that the stimulus they fear no longer results in harmful consequences (Anderson and Insel 319).For instance, the patient is exposed to a previously feared event associated with an unpleasant outcome to get him or her accustomed to the event until he or she does not fear it anymore. Extinction can also occur in a corporate setting. When a company stops giving bonuses to hardworking employees, they may lose motivation to work hard, resulting in a decline in productivity. Based on the examples stated earlier, it could be concluded that reinforcement affects the behavior of individuals, children and adults alike.Reinforcement can either increase or decrease the frequency of a certain behavior depending on the stimulus or reinforcer presented (or removed) after the behavior. Hence, it could be inferred that behavior can be modified according to the pleasantness of the reinforcement that can be experienced for doing a certain behavior. For example, an individual’s positive or desired b ehavior can be maintained with positive or negative reinforcements, while his negative or unwanted behaviors can be extinguished through punishment or extinction.

Air lines industry Research Paper Example | Topics and Well Written Essays - 5000 words

Air lines industry - Research Paper Example Introduction Air travel in the US is a complex industry, whereas its flow aspect – the airlines – is liberalized economically. The airline industry is prone to many guidelines. Moreover, the reimbursement aspects, work regulations and capital of the airline industry still reflect approximately fifty years of political power and protection (Smith & Cox, 2008). The airline industry needs lasting decision-making since it is highly capital demanding. For instance, decisions such as hire, building airport infrastructure, developing route systems or buying aircraft have multi-decade inferences and require large capital investments. Consequently, accounting data in the airline industry is not likely to be the solitary forecaster of future growth opportunities. The 1978 deregulation of the industry eliminated the shields that protected airlines from ecological ambiguity and market rivalry, for example economic recessions and fuel price increases. Hence, following deregulation, it might be difficult to see the clear connection between the firm’s stock proceeds and managers' actions in the airline industry. Moreover, these factors advocate that non-financial approaches might have significant information concerning managerial actions, not enclosed in financial measures. This necessitates including them unreservedly or explicitly in compensation deals which decreases the risk borne by airline managers (Srinivasan, et al, 1998). The decade of the 1980s was a chaotic era for the commercial aviation division in the United States. The deregulation of the American commercial aviation sector in 1978 had totally modified the features of civil aviation in the nation. Prior to deregulation, the federal government had noteworthy influence over routes and fares. Conversely, following deregulation, liberated rivalry steered in a new period in passenger air travel. Airlines discarded smaller cities, assumed ‘hub’ cities, competed with new less signific ant airlines that had entered the market and possibly most essential, decreased passenger fares noticeably. The resultant effects of deregulation, however, proved to be more spectacular for the airlines (Siddiqi, 2009). Ultimate problems affect the industry despite considerable gains of economic liberalization. A number of these problems are transitional, the enormous modifications needed by the end of a half century of severe directive. The regulated airline cartels obtained returns on capital that were supposed to be sensible. Nevertheless, these returns factored in high costs that would frequently not exist in a competitive market. For instance, the airlines’ unionized personnel, founded and reinforced under regulation, gained liberal salaries and unproductive work policies compared with expectation in a competitive market (Smith & Cox, 2008). Major Financial problems The returns of the airlines have not been proportionate with the incomes. For instance, the twelve main U. S. airlines moved from a net profit of $72.5 million in 1955 modest as compared to their $ 1.5 billion of working incomes through a sequence of less gainful years, which comprised a general loss for 1961. At the end of 1962, with net profits of roughly $40 million on revenues of $3.0 billion, the carriers were considerably behind their 1958 and 1959 situations, which effected mainly from non-jet operations (Kerley, 1967). Dempsey (2008) indicates that

English 2 Lesson 6 and 7 Assignments - Essay Example Both: Talented, Athletic, Adventurous, Fun Loving. 2. At different times in A Separate Peace the weather seems to signal a change in the atmosphere of the action. Make a list of three specific weather descriptions from the novel. (You can use page references along with your description if appropriate.) Then, list the corresponding action in the plot. Weather Description: (Pg. 72) "In the air there was only an edge of coolness to imply the coming winter. Plot Developments: Things have changed at Devon, but it's as if Gene and Finny are in a holding pattern. The ease of the summer session is gone, but the horrible events that follow in the winter are still a far way off. Weather Description: (Pg. 12) † A little fog hung over the river so that as I neared it I felt myself becoming isolated from everything except the river and the few trees beside it. The wind was blowing more steadily here, and I was beginning to feel cold.† Plot Developments: Gene describes the weather when he returns to Devon in search of the tree that was the basis of the jump initiation rite of the Super Suicide Society of the Summer Session that they had formed back in 1942. Weather Description: One bleak winter Saturday, Finny proposes the boys hold â€Å"The Devon Winter Carnival.† (Chapter 8). ... What does it symbolize when Finny opens the carnival by burning a copy of The Iliad? Why is it ironic that the Carnival ends with the arrival of Leper's telegram announcing his escape? Use at least two specific details from the novel to support your ideas. Now that Finny has a setback with his broken leg, he wants to train Gene into becoming an athlete and achieving the goals he had set for himself. Always jealous of Finny, Gene is now at peace with himself for taking over this role and considers that he has achieved something. They have decided to celebrate the onset of winter by holding a carnival but the arrival of Leper’s telegram stating that he had escaped the war is disheartening because it seems that none of them are ready to face the realities of life in the real world. Finny’s burning of the Iliad which they had read all summer signifies that the summer has indeed ended and they must prepare for a change in weather (Knowles, Chapter 8). 4. High school students are still reading A Separate Peace more than forty years after its publication. Compose an essay describing what you think the book's enduring relevance is. What do the characters and the conflict say to people today? Do you imagine the book will retain its relevance in the future? Use at least two specific examples from the book to support your ideas. To me the enduring significance of the novel is that it is a coming of age story that is endearing and wonderfully told. It will especially appeal to the male psyche because it shows exactly how boys in a boarding school would behave at that age. The sense of aloofness and loneliness that characterizes their lives at this point could well have been the feelings of a major part of society in those war driven times. Humanity does not like distress

Both the management of diversity and equal opportunities are policies which the human resource department should manage to create strategic plans to implement throughout the organization. Managing diversity recognises that every one is unique and that people have different abilities to contribute to organisational goals and business performance. This is what is termed as a ‘valued-based approach’, which enables organisations progress towards embracing equality. When it comes to equal opportunities organisations aim at following the law and not really harnessing the potential advantage of a diverse workforce or checking to ensure that diversity is not an obstacle to achievement of organisational goals. However, managing diversity is pro-active approach that seeks to root out any unfair bias that affects operational activities, and it goes beyond follow the law to extent it is about being competitive or surviving in the market place. Managing diversity is inseparable from the core functions of the HRM system, as it is connected with the development of communication within the organisation, as well as creating a flexible system of psychological and economic motivation so that to boost the employees’ performance. As the competitive advantage of any company depends upon its staff and their characteristics, diversity becomes crucial to consider while talking about managing personnel. It is essential for the human resource department of companies to integrate the personal attributes of its employees to form a cohesive unit. Social management is therefore an inseparable part of HRM. The end of the 19th century was characterised by a rapid transition from national to multicultural societies, and this transition concerned organisations as well ( ).

Texas City Case Study Essay Example | Topics and Well Written Essays - 2000 words

Texas City Case Study - Essay Example The gas condensed into a liquid that was ultimately ignited by an idling truck. The workers on the crew that overfilled the tank, as well as the driver of the idling truck are in this sense directly responsible for the disaster. They violated proper procedure and those failing to intervene or report these violates are culpable. This culpability is mitigated by the requirement that fatigue workers work 12 hour shifts, in the context of normative, company-led safety violations and lack of safety training, functioning alarms and other safety equipment. The driver of the truck, while perhaps the most proximate individual trigger for the disaster, is fairly neutral in terms of culpability, having no knowledge of the gas inside the tank. Laudability and culpability are mixed, though weighted more toward culpability when it comes to the government body tasked with overseeing workplace safety. OSHA, despite issuing a warning to BP before the disaster, OSHA failed to instigate comprehensive inspections. This lax attitude nullified the lastline of defense against such tragedy. Merritt, lead investigator for the CSB, said that â€Å"the drastic effects of corporate cost-cutting† caused the fire. At the time of the disaster, the company had recently merged with Arco. Low oil prices put pressure on management that ultimately resulted in the most culpable decisions leading to the disaster; lack of investment in plant safety and infrastructure, deliberate skirting of needed safety equipment and precautions, as well as staff cuts and overwork. According to the CSB, BP managers cut capital spending and spending on maintenance in the years leading to the disaster, and following years of low investment. This was, however, an industry norm at the time. Safety features such as alarms were not present or not working, while the layout

The expression of regret is a recognition of the pain and suffering that has been suffered by those who died and others who know them. The words do not imply that BP caused these deaths, or that they accept responsibility for them. The words just regret that something has happened. Because of the location of the incident near the American coastline there was immediate press interest and a flood of images and commentaries on the incident itself and the on-going and severe pollution of the area around the rig. BP was forced to treat this as a major public relations disaster as well as an environmental one and health and safety one. It was the attention of the press over a long period of time that turned this from one incident into a long series of further damaging developments. Not only the leak was highlighted, but also the inability of the company to stop it, and the inadequate clean up and recovery attempts. â€Å"We have acted to take responsibility for the clean-up, to respond swiftly to compensate people affected by the impact of the accident, and to look after the health, safety and welfare of the large number of residents and people who helped respond to the spill. As of 31 December 2010, we had spent $17.7 billion for our response activities. Throughout, we have sought to work closely with government, local residents, our shareholders, employees, the wider industry and the media. â€Å" (BP oil 2011) The

Crime Mapping and Crime Pattern in Modern Police Work Essay

Crime Mapping and Crime Pattern in Modern Police Work - Essay Example Therefore, the future f policing will continue to change however, as the future f policing changes so does the issues which can arise for individual police officers, police management and issues relating to the community. Terrorism is the issue on everyone's mind these days. Terrorism is a global disorder which American's have been fighting, and probably will be fighting for many years to come. Terrorism can be hard to define because throughout history the definition people use to define terrorism has changed as terrorism has changed. One may think terrorism has come to an end however, just when terrorism stop's being a focal point terrorism will return. Terrorism is something most people are going to be combating for many years to come. As soon as people feel the chances f a terrorist attack are over most people become comfortable and let down on terrorist defence. Americans have been lucky with few terrorist attacks on U.S. soil. However, other countries such as Iraq have not been so fortunate. Therefore, Americans should feel a sense f freedom and pride in knowing terrorism has not been a continuous problem for the United States. Future policing rely mainly on the type f society being policed-the social, economic and political realities and in more-developed countries, the technological sophistication f the populace.(Stephens, 2005) The key to policing in the future is to be able to work with the communities hand in hand. As an individual police officer, it would benefit the officer and the department as a whole if neighbourhoods and businesses would join in the efforts to monitor their communities. What is an individual police officer's role in the future f policing and terrorism The job f a police officer is complex along with demanding and dangerous. Police officer's may handle situations ranging from a routine traffic stop to a pursuit where an individual is armed and dangerous, a police officer relies on current technology and equipment which is an essential tool f his or her trade. In the twentieth century the advancement f technology proved to be effective in both control and perpetration f crime due to the rapid acceleration. Police officers are provided with technology that is constantly being defended by the offensive creations and implementations by the criminal element in society. To protect the communities every body is going to have to participate in keeping our homeland safe. There are several advances in today's technology, which likely will cause issues that causes an affect with policing. Technology is also going to be a key factor in policing against terrorism. With the internet reaching across the globe and a person's ability to access almost any information, the internet may be deemed as one f the biggest threats in aiding terrorism. Police officers are going to have to receive precise training to be able to keep up with the terrorists Police management is an essential part f a well-working counter- terrorism strategy. In the future terrorist attacks could tear the United States apart. Good police management is one way to ensure terrorist attacks will not escalate out f control. If a police department is not well-managed and prepared for a terrorist attack the police could lose control f

Countermeasures to Automobile-Exhaust Pollution Essay Example for Free

Countermeasures to Automobile-Exhaust Pollution Essay The world motor vehicle population exceeds 1 billion units at the moment. These vehicles are used for transportation of people and products across various places around the world. As a result, they emit many pollutants. This is attributable to the action of their engines burning fuel to release energy, which is an inefficient process. Firstly, they release particulate matter consisting of both organic and inorganic substances into the atmosphere, through exhaust emissions. Secondly, they release Volatile Organic Compounds (VOCs), which have carcinogenic effects. Pollution from vehicles is a universally acknowledged problem. However, it varies depending on the nation and its population. For example, pollution from cars contributes to between 50 to 90 percent of the total in urban areas. This may not be the same for rural areas. However, motor vehicles still present a disadvantage to the environment and human life. It is, therefore, prudent to develop countermeasures to automobile-exhaust pollution. Most of the world’s vehicles are operated on conventional hydrocarbons such as diesel and gasoline. By switching to fuel that maintains less pollution, the environmental impact of vehicles can be minimized. An alternative fuel technology that has the potential to meet this challenge is fuel cells. In this technology, hydrogen has maintained the best promise as a candidate to replace petroleum-based fuels. This technology utilizes hydrogen gas to create electricity. This electrical energy is converted to mechanical energy through an electric motor, which makes the wheels of an automobile to rotate. In this process, the emissions developed are pure water, Carbon (IV) Oxide and various oxides of nitrogen. This emissions are attributable to difficulties in storage and commercial production. Despite the release of oxides of carbon and nitrogen into the air, hydrogen fuel cells have a smaller footprint on the environment, when compared to conventional gasoline engines. However, such inefficiencies can be eliminated through use of concrete, as researched by a study at the University of Eindhoven (Yirka npp). The easiest method for manufacturing hydrogen gas at the moment requires mining fossil fuels, which has an environmental impact in its own right. However, new production techniques such as bacteria and biomass waste are expected to become conventional in the coming years. This will reduce the environmental impact of fuel cells, since the technology will lower oxides released into the air (Katsuhiko 3371). A hydrogen fuel cell works by the introduction of hydrogen at the cathode and oxygen at the anode. In the process, water is released out. Anions and cations from the cell are harnessed at the respective terminals, and energy is released. Hydrogen has a high energy content of around 150MJ/Kg or 61,100 BTUs per pound. This exceeds gasoline and its 20,900 BTUs of energy per pound. High energy content implies that less fuel is required to maintain the same amount of power in engines, or to travel the same distances. Similarly, it has a higher efficiency when used in combustion engines. Advanced hybrid engines such as that of the Prius maintain an efficiency of about 40% (Potera 38). However, hydrogen has an efficiency of about 75% when used as the lone source of fuel. This efficiency means that greater distances can be covered with less consumption of energy. However, introduction of additional hydrogen fuel cell cars has been hampered by infrastructural issues. There are limited facilities that allow fuelling to conventional commuters within their localities (Katsuhiko 3369). There are many electric cars (EVs) on modern roads. Examples may be seen from Tesla’s roadster and the Nissan Leaf car. These vehicles release virtually no emissions to the environment, therefore are a solution to automobile-exhaust problems. This is attributable to their engines, which do not burn fossil fuels in order to release energy. Electric cars use sets of linked batteries as their primary source of energy. These energy sources comprise materials such as lithium, lead and nickel-metal hydrides. These batteries typically consist of thousands of cells such as the lithium-ion type. They store energy that has been harnessed from electrical outlets at home, or the recharging stations that are found in some major cities. In the example of the Model S, the vehicle is charged through a ‘high power wall charger’. This device is replenishes the batteries around twice as fast as conventional power outlet would manage. Electric batteries are used to operate everything in the vehicle. They are used to run a controller which serves to run an electric motor. This motor is what rotates the wheels in EVs. Through recent breakthroughs in manufacturing, EV batteries can be mass-produced. There are now lower costs of ownership and maintenance to the consumer, when compared to the past. Batteries have a very high energy density, when compared to fuel cells. As a result, they offer higher mileage than traditional fuels. The Tesla Model S provides a good example of mileage. It can manage about 300 miles of travel at a speed of 55 miles per hour, out of its lithium ion batteries. Even conventional lead-acid batteries allow a range of 80 miles. EVs are characterized by high torque and low speeds. They are, therefore, very useful for usage within cities, where many vehicles are located in smaller vicinities than rural areas. They will help in reducing urban pollution since they do not release exhaust into the environment. The production of EVs often has higher environmental pollution than conventional cars (Lave and Hendrickson et al. 993995). Improvements in production are needed for the solution of such issues. However, the usage of such vehicles is limited by infrastructural issues, just as the hydrogen fuel cells. As a result, the Environmental Protection Agency (EPA) has highlighted that only 4,000 EVs are currently running on American roads. This contrasts to gasoline-based vehicles which are in the millions. New breakthroughs in charging and fuel range are required for such EVs to gain critical mass of commuters. The larger the distance a vehicle is driven, the more pollutants it releases to the environment. According to the EPA, over one third of smog emissions are attributable to vehicle use in urban areas. However, more people have taken to the roads since the 1970s. Similarly, they have driven for longer miles hence attenuated the pollution problem. This has only served to attenuate the problem at hand. People usually drive for many reasons. Firstly, it may be as a means for arriving at work. Secondly, they do it to access leisure areas such as parks. Thirdly, they drive to shopping centers to do their groceries. There are ways that people can drive fewer miles while accomplishing all these needs. Firstly, they can involve themselves in carpools. This refers to the sharing of cars on journeys, between different people, such that several people drive in one car simultaneously. This is useful in that lower miles are collectively driven, hence reduced environmental pollution from exhausts. Through carpooling, people can get to work or leisurely places without inconveniences such as fuel costs, long drives and pollution. Carpooling is possible through websites, apps and pickup points. Use of public transport vehicles also achieves the same effect. People should use buses and other public transport means, whenever possible. Secondly, people can reduce the environmental footprint of their cars by combining errands into a single trip. This is especially useful in the case of families that own multiple cars. Instead of sending different people to pick up items needed by the family, one vehicle may be used to collect all these items. Shopping often requires the use of vehicles, since the luggage may be overbearing. In that respect, pollution can be reduced through use of the efficient e-commerce platforms such as Amazon. Individuals are able to meet their shopping needs while reducing their environmental footprint. The use of trucks for shipping goods is also useful since it allows collectively leaner environmental emissions when compared to many cars operated by shoppers. The internet has allowed various individuals to work at home. Similarly, it has enabled people to telecommute. It would, therefore, be environmentally beneficial if people used these tools instead of driving to work on each applicable day. These measures also reduce congestion in traffic. There will be fewer vehicles on the road, thus fewer delays that accumulate into environmental pollution through release of exhausts. In the modern world, settlement has been defined by work and educational opportunities. For example, people try to live as close to work as is comfortably possible. This has been attributable to efforts in reducing travel times, as well as associated fuel costs. According to the United States Census Bureau (npp), over 10 million Americans travel an hour each way to work. This has provided a challenge to the country’s urban planners and engineers. There has been a trend in altering commuting patterns through development of areas that provide ‘walkable communities’. This concept implies areas that require less motorized movements in order to get around (Fullerton Gan 303). Through walkable communities, commuters would be able to reduce their environmental footprints as they get around. Residential, leisure, business and industries are developed in a common area such that people get to each point devoid of cars. Alongside reduction of pollution, the quality of life is also improved for people residing in such locations, since they are able to exercise. Through use of alternative fuels, environmental emissions can be reduced. However, arguably the best approach to reducing such wastes would be an alteration of driving habits. In that respect, an effective method for reducing both fuel consumption and environmental emission would be a reduction in vehicle idle time. When people sit in their cars while their engine runs, they release exhaust just as they were driving. This happens during conditions such as traffic among others. In that respect, it would be prudent if people learn to switch of their engines in such circumstances. Manufacturers should also implement the start-stop systems across a wider range of cars. This will allow engines to switch off, when the cars are stationary. By stepping on the gas pedal, vehicles are able to start their engines immediately. This reduces the annoyances associated by drivers to starting their engines again. Cars of the past featured inefficient engines. They released more particulate wastes into the environment, while consuming more fuel than contemporary variants. However, some of these cars are still in service today. Despite good maintenance, older vehicles become less efficient than their original state. . Drivers should be encouraged to drive newer vehicles. For example, modern cars such as the Prius offer nearly triple the efficiency of older cars, in terms of fuel consumption and environmental consumption. Newer cars also adhere to modern emission controls that are set by the EPA and other responsible bodies (Dennis-Parks 799). In the United States, public transportation policy has been left to local authorities in cities and towns. As a result, the country lacks a homogenized transportation system. Schedules for buses and trains have difficulties in being followed. These systems are also characterized by slow speeds of movement. This has created frustration among users, who view cars as efficient modes of transportation. Similarly, American culture has often painted a tainted picture on public transport systems. The car has been portrayed as a symbol of achievement. The converse has been applied for transport systems such as buses. The American Public Transport Association states that usage of public transportation results into savings of over 35 million metric tons of Carbon (IV) Oxide on an annual basis. By switching to public transport for the average American round trip of 20, miles daily, an individual is able to reduce their annual emissions by over 4,000 pounds (Fullerton Gan 303, 304). Going to work is one of the key reasons behind owning a car in the United States. In that respect, companies can make a significant contribution to the efforts against environmental pollution. Firstly, they can provide shuttle bus services to their employees. In that respect, they can purchase or hire buses that will pick up and drop off employees at designated points, on each work day. This will assist in reducing vehicle emissions due to ride sharing. This can be seen through Google, which operates shuttle services for its employees. Secondly, companies can post ride-share boards in their premises. This will allow employee who live close to each other to commute on a single vehicle, thus saving fuel and the environment. Some companies have also assisted employees through creation of car cooperatives. These are services that allow employees to rent cars from a set location. In return, the employees pay small fees for their use of the cars. Such systems are very useful for people working in inner city districts, who need cars only on a rare occasion. This encourages them to use public and shared transport, as opposed to personal vehicles. It is estimated that the global urban population will almost double by the mid-21st century. As a result, alternate means of transportation need to be crafted for the urban populations. The use of motorized vehicles will only result into further environmental pollution in such areas. Urban dwellers will consequently be exposed to poor health and effects such as smog. In that respect, local authorities need to establish policies that encourage non-motorized commuting. Bike sharing programs are similar to car cooperatives, only that they are not characterized by polluting effects (Fullerton Gan 301). Different cities have made attempts at bike sharing programs. However, they are not meant to eliminate the use of motorized transport completely. Public transport and cars is used for commuting to centralized locations, where bicycles can then be accessed for movement within urban areas. Errands that exist within a radius of one mile are practical by foot. Similarly, bikes are useful for errands within five miles, which characterizes the inner city. Various cities around the world have embraced such measures. For example, the Chinese cities of Beijing and Shanghai have bike sharing programs that have operated very well. Cities may also embrace some measures, which may be rather draconian. For example, cars whose registration ends with odd numbers may be allowed access to roads on particular days of the week. This measure will allow a curtailment of excessive vehicles on roads. Similarly, it will encourage ride sharing programs. Cars have an impact on environmental pollution, especially in the urban context. In that respect, several measures can be observed, in the efforts of reducing exhaust emissions. New technologies such as hydrogen fuel cells and EVs will be useful in reducing emissions such as the oxides of carbon and nitrogen. However, of greater use is the adoption of efficient driving habits by commuters. Car manufacturers also have a role in the reduction of emissions. By rolling out start-stop technology to all cars, high environmental savings can be recorded. Driving to work is an important part of many American lives. Companies can assist in environmental efforts by providing their workers with ride sharing and shuttle facilities. Companies such as Google and Apple present a good example of how this can be implemented. Similarly, local authorities and urban planners have an important role in designing cities that will require little use of motorized vehicles. Through implementation of such measures, massive savings on environmental pollutants can be recorded. Works Cited Dennis-Parks, Reda M. Instructing the EPA How to Regulate Vehicle Emmissions.

Cogeneration And Trigeneration Methods Engineering Essay

Cogeneration And Trigeneration Methods Engineering Essay Cogeneration and trigeneration are methods used for producing more than one useful form of energy from only one energy source. These two methods in todays world are very important because efficiency, fuel prices and emissions are a great a concern. Both methods give the opportunity to increase efficiency drastically up to 60% to 80% which is much more than the conventional power plant which has an efficiency of about 30%.  [1]   The 60% to 80% efficiencies that both methods present have a great effect on cost savings, reduced air pollution, greenhouse gas emissions, increased power reliability and quality, reduced grid congestion and avoided distribution losses.  [2]  All these factors mentioned, as discussed before are all important and cogeneration and trigeneration help achieve this. Both systems are normally combined but I will explain both cogeneration and trigeneration separately and then give examples were these systems are used in real life. Cogeneration Cogeneration is also known as combined heat and power (CHP). Plants using a cogeneration system use the exhaust of for example a reciprocating engine to heat the premises. This means that instead of throwing away the exhaust, it is being reused but this time as heat energy. This is done by using a heat exchanger to transfer heat from the exhaust gas to process heat. Cogeneration produces a given amount of electric power and process heat with 10% to 30% less fuel than it takes to produce the electricity and process heat separately.  [3]   Cogeneration Combined Heat and Power Figure 1: Cogeneration diesel engine generator plant  [4]   Figure 1 above shows a diesel engine driving a generator. Fuel in the form of natural gas, bio gas or bio diesel is used to run the engine. The engine is coupled to a generator which produces electricity. The plant above shows two heat exchangers, one for cooling the engine and raising the used cold water coming from process heat and the other is an exhaust gas heat exchanger only to raise again the temperature of the water for process heat. The water cooling the engine which is normally at around 90oC enters the heat exchanger (bottom one) which by heat transfers and the second law of thermodynamics is cooled but the cold waters temperature is raised. In the exhaust gas heat exchanger the temperature of the water already heated in the bottom heat exchanger is heated again and sent for process heat. A simple example is, imagine a hotel having a generator to produce electricity and at the moment its full of guests and the ambient temperature outside is around 2oC below zero. This means that the central heating needs to be running constantly to keep the guests in a comfortable environment. Therefore a lot of fuel is being used to heat up the boilers to produce steam for central heating. Imagine the hotel employs the plant shown in figure 1. No fuel will be used for heating because the fuel used to run the engine is also being used (indirectly) for process heat. There exist two main types of cogeneration techniques which are topping cycle and bottoming cycle plants. Topping cycle cogeneration plant Topping cycle plants generate electricity or mechanical power first. Some facilities may generate the electricity for themselves only and some may even sell any power that is not being used. There exist four types of topping cycle cogeneration plants. Combined cycle topping system The first type burns fuel in a gas turbine as shown in figure 2 or diesel engine to produce electrical or mechanical power. Process heat, or steam that then drives the secondary steam turbine is produced by the exhaust entering a heat recovery boiler.  [5]   Figure 2: Combined cycle topping system  [6]   Steam turbine topping system The second type of system burns fuel which can be any type to produce high-pressure steam that then passes through a steam turbine to produce power. The exhaust provides low-pressure process steam as shown in figure 3.  [7]   Figure 3: Steam turbine topping system  [8]   Heat recovery topping system This type burns a fuel such as natural gas, diesel etc. The cooling system (engine coolant) goes to a heat recovery boiler, where it is converted to process steam and hot water for space heating. Figure 4: Heat recovery topping system Therefore this type produces electricity, process steam, hot water supply and heating as shown above in figure 4.  [9]   Gas turbine topping system This type of system uses a natural gas turbine to drive a generator. The exhaust gas goes to a heat recovery boiler that makes process steam and process heat as shown in figure 5.  [10]   Figure 5: Gas turbine topping system  [11]   Bottoming cycle plants These type of plants are less common then topping cycle plants. Normally this type of plant is used in heavy industries where high temperature furnaces are used. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga9XEwd5hBpqSz-qPZFuf_Ys3R6md71O2RaAf3mJyaEHJ0m3V6gbMBeon_5xhe7Oph5CkvZFE4zRAwHNVkJRh4dp769tb-Z6-4rJnMZu9iwFWqAby13z3li9QuYjXE4qM-40Jme82ilHM/s1600/bottoming-cycle-system-cogeneration.jpg Figure 6: Bottoming cycle system  [12]   After heating the furnace or any manufacturing heating process the waste heat is then passed through a recovery boiler. The waste heat is used to produce heat which then drives a steam turbine to produce electricity. Trigeneration Trigeneration also referred to combined heating, cooling and power (CHCP) is a system where this time three types of energies are produced from one energy source. The difference between cogeneration and trigeneration is that in trigeneration chilled water for air conditioning or process use is produced. This is done by using an absorption or adsorption chiller. Just as a cogeneration power plant captures and makes use of the waste heat, absorption or adsorption chillers capture the waste (or rejected) heat and produce chilled water.  [13]   Therefore the major advantage over cogeneration is that now if a plant works using trigeneration, hot water, air conditioning (using chilled water) and power generation. Therefore an industry having this system will spend less money due to having a more efficient plant when compared to cogeneration and especially when compared to conventional plants. Adsorption Chiller An adsorption chiller works purely using hot water. It uses the principle of using solid sorption materials such as silica gel and zeolites. http://www.raee.org/climatisationsolaire/graph/new/adsorption_sh.gif Figure 7: Schematic for an adsorption chiller  [14]   These type of chillers have a strong structure and are easy to install. There are no possibilities of crystallization, corrosion, hazardous leaks, and the electricity consumption is minimal  [15]  . They are commonly used in a commercial environment. Absorption Chiller An absorption chiller works by using hot water, steam or combustion. The solution used contains water and lithium bromide salt to absorb heat from the surroundings. No refrigerant is used which means no harm is done to the environment. http://www.raee.org/climatisationsolaire/graph/new/absorption.gif Figure 8: Schematic for an absorption chiller  [16]   Absorption chillers are the most distributed worldwide and they are more efficient. Their lifetime is much longer than adsorption chillers. Moreover they have high maintenance time and low corrosion protection.  [17]   Say something small about trigenerators and put schematic of plant.

Essay on Female Companions in The Awakening and A Dolls House

Importance of Female Companions in The Awakening and A Doll's House      Ã‚  Ã‚   Female companions are very important to the development of the main characters in Kate Chopin's The Awakening and in Henrik Ibsen's A Doll House. Mademoiselle Reisz and Madame Ratignolle, in The Awakening, and Kristine Linde, in A Doll House, help Edna Pontellier and Nora Helmer discover their inner selves.    Mademoiselle Reisz, Madame Ratignolle, and Kristine Linde all act as role models for the protagonists. Edna deeply admires Mademoiselle Reisz's piano playing.

Personal Essay - I Welcome the Challenge -- Personal Narrative, essay

I have learned a great many things from playing soccer. It has changed my entire outlook on and attitude toward life. Before my freshman year at Cool high school, I was shy, had low self-esteem and turned away from seemingly impossible challenges. Soccer has altered all of these qualities. On the first day of freshman practice, the team warmed up with a game of soccer. The players were split up and the game began. However, during the game, I noticed that I didn't' t run as hard as I could, nor did I try to evade my defender and get open. The fact of the matter is that I really did not want to receive the ball. I didn't' t want to be the one at fault if the play didn't' t succeed. I did not want the responsibility of helping the team because I was too afraid of making a mistake. That aspect...

One Tear That Meant the World :: essays research papers

I have always enjoyed having a best friend that was male. Whether we were swimming, jogging, fishing, or just talking for hours, I never got bored. We balance one another. I will never forget the day I lost that all. The day my best friend left ended up touching me the most.   Ã‚  Ã‚  Ã‚  Ã‚  When I stepped outside, the pavement felt like ice, yet the air had a warm breeze to it. It was a gorgeous August day. Not a single worry mingled in the air. The birds were chirping long, beautiful melodies. Melodies I had heard many mornings that summer. They sang when it was going to be a wondrous day. Nothing seemed wrong to anyone except to me. Today, my birthday, August first, my best friend was leaving for the Navy. He was going to serve our country. For six dreadful years, I’d have to live without him. The only communication would be a few cards and letters and one long distance call. This day reminded me of those long rainy days, the days where the clouds blocked out the suns bright rays of sunlight.   Ã‚  Ã‚  Ã‚  Ã‚   The clock finally struck four and it frightened me because the sweet sound of the clock seemed loud and harsh. It sounded kind of like I was in a horror movie. I dreaded walking across the street to say good bye to my dear friend, but I knew I had to go. As I walked across the street it seemed like a mile. My legs ached and my throat was dry. I could hear the pattering of my feet on the pavement and the thud of my heart racing about ninety miles a minute. I just wanted to run up to him and beg him to stay, but I knew I couldn’t do that. I finally walked up to him and started to cry. I cried as though I had lost someone close to me, but I hadn’t. There was a part of me that was dying. My heart was aching and I couldn’t stop it. I hugged him for five minutes, but it only seemed like seconds. My tears started to disappear. He let me know how much he’d miss me and how he couldn’t believe he was leaving. I could feel the tears starti ng to come again, but I kept them in. I knew there was something I wanted to say, but I couldn’t.

Relflection Paper Essay

When enrolling into a new class, it is normal to have expectations. I am excited and nervous at the same time. I understand that the upcoming semester will provide many challenges I will have to face. I am excited to see how I will grow academically over the course of the semester. I find myself eager about learning new things and refreshing my knowledge on things I have forgotten. It has been a long time since I have studied the growth and development of humans. I have strengths to bring to this class as well as weaknesses that I plan to work on during this class. By the end of this course I expect to be able to apply what I learn in counseling and become a better writer. While this class will be more stimulating than what I have been used to I hope that with the help of my classmates and my professor I can make this class a positive learning experience. During my undergraduate career, I took many psychology classes involving the human development. In one of my undergraduate classes, Lifespan Development, we went through the lifespan of people from birth until death. I took this class online and the class involved a lot of self-teaching. Because the class was online, assignments consisted of mostly online tests. While I learned a lot, I do not feel as if I learned all that I could. I am looking forward to taking this class on a more challenging level and having a deeper understanding in human growth and development. One of my biggest weaknesses is engaging in class discussions and presentations. Although I have an extroverted personality, I am very shy when it comes presentations. It takes time for me to get comfortable speaking in front a group of people. While doing presentations and engaging in class discussions, I get very nervous. In this class, a big part of my grade comes from this. Therefore, in this class I expect to get over my fear of public speaking. I hope that with the help of my professor I gain confidence about speaking in front of groups of people. I want to be able to take what I have learned in this class, apply it to counseling and also have a better understanding of what I have learned. This class will be an introduction of what to look forward to for the next three years. I am not used to writing papers and having to do so much reflective thinking. I believe this experience will help me become a better writer. In order for me to achieve all of my expectations, it is important that my professor help me when I need it, challenge me and give me constructive critism. In addition, if I want to take all that I can from this class it is imperative for me to give this class all that I have and spend time reading and completing my projects. I know that during this semester, there will be challenges but with the instruction of my professor, I plan to grow in my profession.

The Secret of Ella and Micha Chapter 8

EllaI realize I have more issues than I thought. As soon as we turn onto the Back Road, a passion combusts inside me. It only flames hotter when we pull up to The Hitch, an old abandoned restaurant stationed at the end of the road.Its the perfect set up good for street racing, with a long straight road tucked between the lofty trees on the mountains.We still should talk Ella! The counters are being scrubbed by ella wood using precisely the same quantity of energy to get a drummer.He pulls the car to the side, maneuvering carefully across the pot holes. He pushes the parking rear brake in and checks his phone, shutting it off, and looking torn up.â€Å"Whats wrong?† I ask. â€Å"You look upset?†Ã¢â‚¬Å"Nothings wrong.Umm Caroline needs you to receive ready.

Itll ruin your whole Im-neutral-and-dont-give-a-shit act.†I opt to remain impartial. â€Å"Who are you planning to race tonight?†Ã¢â‚¬Å"You mean who are we racing?† He smiles alluringly through the full dark cab of the car. â€Å"Well, I thought Id leave that up to you.Ethan slaps the rear of my mind.† I rub my broad forehead with the back of my hand. â€Å"Does he still got that piece of crap 6 cylinder in his Camaro?†Ã¢â‚¬Å"Yeah, he does.† Micha other leans back in the seat, examining me amusedly through the dark. â€Å"You think thats who I should go for?†Ã¢â‚¬Å"Its the obvious choice.No suspects are arrested.

†Ã¢â‚¬Å"You think I should take on special someone in my own league?†Ã¢â‚¬Å"If you want the win to mean anything, then yeah.†We look at each other, like magnets begging to last get closer. Yet flip one the wrong direction and they will push apart.â€Å"So which one is it, pretty girl?† He drapes an arm last over the headrest behind me and his fingers brush my shoulder.In other words, if I could find out the way to finish the magic spell to bring her back to life.â€Å"Micha, I think we should go back.† I put my seatbelt back on. â€Å"This isnt my thing anymore.†He small presses his lips together firmly.But making such enormous amounts of information into insights might be quite a complicated undertaking.

Was it bad news on that full text you got?†He traces the figure eight tattoo on his forearm. â€Å"Do you remember when I got this?†I absentmindedly touch my lower back. â€Å"How could I forget, since I have the same one on my back?†Ã¢â‚¬Å"Do you remember why we got them?†Ã¢â‚¬Å"I cant remember anything about that night.†Ã¢â‚¬Å"Exactly, yet youll remember it forever."Micha is an intriguing title.â€Å"Do you want to much talk about it?†He shakes his head, still focused on the tattoo. â€Å"Nah, Im good.†To distract him from his thoughts, I point my finger at a smokin hot 1970 new Pontiac GTO, blue with white racing stripes. â€Å"What about Benny? Does he still have the 455?†Michas eyes are pools of black liquid.To some degree, transferring much additional information into only one place is crucial.

Im not racing unless youre in the car with me. Its tradition.†A starvation inside me emerges. â€Å"Alright, Ill free ride with you, just as long as you do one thing for me?†Ã¢â‚¬Å"Say it and its yours,† he says without blinking.Not worth while youre still coherent, anyhow.His face is indecipherable, his breathing fierce, his gaze relentless. â€Å"Okay, then. Lets go win us a race.†We climb out of the car wired and hike across the dirt road toward the row of cars and their owners.Since you dont need to.

†Ã¢â‚¬Å"Well, what do we have here?† Mikey, the owner of the Camaro, strides up to us. Hes got black hair, a kink in his nose, and his thick neck is enclosed with a barb-wire tattoo. â€Å"Is the infamous famous duo back again to get their asses kicked?†I roll my eyes. â€Å"You beat us once and that was by default due to a flat tire.It doesnt mean anything to anybody who matters.†Micha squeezes my shoulder, trying to keep me calm. â€Å"So whos up first? Or has no one decided yet.†Mikey eyes Michas Chevelle and theres a nervous look in his eyes. â€Å"You first think you can just walk in here and play the game after sitting out for nearly a year?†I mouth to Micha, a year?Micha shrugs."Yeah, but it was not a huge thing.

†Mikeys laughter echoes the night. â€Å"You and what army?†I point at Michas Chevelle parked near the road. â€Å"That army right there.†Mikey shakes longer his head and shoos us away.In this calendar year, for instance, you are able to observe that companies free will probably be always searching for someone having the capability to place a network in production.â€Å"As opposed to yours?† I retort, getting into Mikeys face. â€Å"Because that things all looks and no go.†Micha directs me back by the shoulders and a trace of amusement laces his voice. â€Å"Easy there, tiger.Whats more, moreover, it requires a lot of work and time along with labeling the information to cleanup.

Mikey points a finger sharply at me. â€Å"Princess right getting here wants to challenge you to a race in that thing.†Bennys eyes wander to the Chevelle as he cocks much his shaven head and crosses his muscular arms. â€Å"Micha, isnt that your car?†Micha pats my back and winks at me.There were not any military secrets with me.In fact, it might be kinda nice to have a challenge for a change.† Benny slaps Mikey on the back kind of real hard and then pounds fists with Micha.â€Å"Thanks man,† Micha says with a respective nod. â€Å"Are you and I going to line up first then?†Benny bobs his head up and down, nodding as he stares at the road pensively.Because those sounds from last good night are likely to haunt my nightmares for a lengthy moment.

â€Å"Because beating him wont be easy.†Ã¢â‚¬Å"Youre my plan.† He opens the passenger next door for me. â€Å"With you in the car, theres no way I wont win, otherwise youll never let me live it down.Probably other people today are beginning to think things.† He slides across the front of the hood and climbs into the drivers seat.â€Å"Youre such a show off,† I remark.He starts up the engine and it thunders to life. â€Å"Thats like the pot calling the kettle black.Her mother was like that lots of occasions.

You were standing on the roof with a snowboard strapped to your feet, telling everyone you could make the jump. I think thats pretty close to showing off.†I make an innocent face. â€Å"But I did make the jump, didnt I?†Ã¢â‚¬Å"Yeah, but not without breaking apply your arm,† he says.You might need to understand that maybe she does not wish to go captured.â€Å"I was there because I wanted to be.†Ã¢â‚¬Å"You missed a first performance because of me.†Ã¢â‚¬Å"I dont care – never have.†My gaze involuntarily flicks to his lips."Alright, youre in need of a workout.

He shoots me a smug look, cocking an eyebrow. â€Å"Now thats showing off.†Shaking my head, I restrain a grin. Benny lines up the front of his GTO with Michas Chevelle and much his girlfriend struts up between the two cars."I didnt need to think about anymore.â€Å"When did they get here?†Micha ignores me, eyeing Benny through his rolled down window. â€Å"To the baseline logical and back?†Bennys arm is resting casually on top of the steering wheel. â€Å"Yeah, man. First one back wins.Im convinced you dont have to hear it.

Go!† Her hands young shoot down and screeches cut the air. A trail of dust engulfs us as we race off. The trees on the side of the road are a blur, and the sky is one big streak of stars. I keep silent as Micha shifts the car over and over again, but something inside me awakens from a very deep sleep.Micha has a thing for flipping the car around, without decreasing the acceleration. Its scary as hell, but it works every time. Besides with the longer body of Bennys GTO it doesnt have quite the turning power.We reach the end and I should probably be nervous.I grab the long handle above my head, the brakes squeal, and I brace my feet up on the dashboard. Its like being on a merry-go-round on crack. Everything spins – the trees, the sky, Micha. For a second, I shut my eyes and it feels such like Im flying.By the time were speeding up the road again, hes a small distance behind us. Micha punches the gas and major shifts the car into a higher gear.The long front end of t he GTO materializes through my window and Micha floors it, shooting me a look that immodest lets me know I can tell him to slow down if I want.I dont.

Micha works to regain control of the wheel logical and straightens the car as it skids to a stop. Everything settles and the dust slowly clears. Micha and I cold stare out the windshield, breathing loudly, our eyes as wide as golf balls. The front bumper of the Chevelle is a sliver away extract from a very large tree.Im an adrenaline junkie. Plain and simple, but I think its how Ive been all along. I just never admitted.Im no longer in control.His hand comes up behind my head and he entices my lips back to his.Something snaps inside me, like a rubber band. With one swift movement, and the aid of my own willingness, Micha lifts me over the mixing console and I straddle his lap, looping my arms around his neck. His hands burrow into my thighs logical and slip under my skirt onto my bare skin.â€Å"Stay here, baby,† he whispers, like he can read my thoughts. â€Å"Trust me, okay? Dont run.†He busy waits for me to nod and then crashes his lips into mine, keeping his h ands under my skirt. I arch my body into him, pressing my chest against his, and my nipples tingle.

It sends a shock through my body and my legs uncontrollably tighten around him, my knees pressing into his sides.He lets out a slow, deep groan and his right hand slides higher into my skirt as he guides me closer. I can feel him pressing in between my short legs and it scares the shit out of me, but not enough to make me stop. Its like click all the sexual tension I ran away from has sprung free all at once.â€Å"Are you two having fun in there?†I jump back and my cheeks start to heat at the sight of Ethan and Lila staring at us through the window. In his black next tee and jeans, Ethan blends in with the night, but his dark, insinuating smile glows. Lilas eyes are magnified and how her jaw is hanging open. Micha does nothing to help the situation.â€Å"So who won the race?† I ask, smoothing the last of the wrinkles out of my skirt.Ethan smirks at me. â€Å"Is that what youre really thinking about at the moment?†I stare at him blankly. â€Å"What else wou ld I be thinking about?†Micha climbs out of the car, stretching his long legs.†Micha interlaces our fingers. â€Å"So the same old, same old.†Ã¢â‚¬Å"You know how these things go.† Ethan pats Michas shoulder sympathetically.

I cant crush him. I need to repaint the lines somehow.â€Å"We should just leave,† Micha says to me. â€Å"Lets not even give how them the benefit of our argument.†I let out a shaky breath and nod. â€Å"That sounds good to me.†Ã¢â‚¬Å"You want to meet up at the house?† he asks Ethan. â€Å"Im sure were going to have to do some tuning up on The Beast after what I just did.†Lila laughs. â€Å"Oh, I get it. Although, I like my name better.†Micha traces his thumb along the palm of my hand.†Ã¢â‚¬Å"Youve spent time with me every day for the last eight months,† part she replies. â€Å"I think were good for a few hours.†Ã¢â‚¬Å"Ill take care of her.† Ethan chucks the empty bottle of soda across the parking lot and it lands in the back of his truck.
