Kaesung Industrial Complex in North Korea research paper

Kaesung Industrial Complex in North Korea - Research Paper Example plex is a result of the attempt to improve relations between South Korea and North Korea made by Hyundai Group beginning in 1998 that coincided with the Republic of Korea’s policy (Manyin 5). In addition to this, several dozen South Korean companies had facilities there which include chemical, machinery, textile and electronics factories (Britannica.com). Most of the employees are from North Korea, but still, there are people from southern part too and all together they create a cheap labor for the South. Moreover, it is a duty-free zone that has no restrictions on the use of foreign currency or credit cards (Manyin 6). However, the political situation also plays an important role in the relationships between two countries. For example, the deteriorating inter-Korean relations in 2013 led to both countries’ withdrawal of their employees from the industrial zone. Furthermore, this city is an important cultural and educational center. There were many tombs, palaces and te mples which were destroyed during the war, but hopefully many of them were restored and were designated a UNESCO World Heritage site in 2013 (Britannica.com). The Kaesong Industrial Complex (KIC) is an economic enterprise in which companies of southern Korea have set up factories in a North Korean enclave ten miles north of the demilitarized zone. Although, it is a way for South Korean companies to use cheap labor from North Korea for low-end products. The president Roh Moo-hyun who was a liberal, tried to make Kaesong economically viable. He provided the foreign markets with goods which were produced in the complex. In addition to this, his administration made a lot of attempts to gain a duty-free status for products of Kaesong. Roh tried to place the language in the KORUS FTA. The United States refused to include this language in the agreement because it would give certain benefits to North Korean regime. It is actually the last example of the inter-Korean cooperation projects. Their relations

Proposing a solution - Essay Example Areas around notice boards are also vulnerable to a lot of littering especially when poster papers fall off or are deliberately/ accidentally pulled down by students. Careful observation of the campus population reveals that different people litter for various reasons. For one, most persons who do the littering usually feel that the have no sense of ownership or responsibility of the campus, and so its state becomes of little concern to them (Dasmann, 34). In addition, such people often argue that even if they litter around there are those employed to specifically pick up the litter and clean after them. Many would, in this wavelength, cite the fees they pay for maintenance and the consequent budgeting by the university to consider such things as the cleanliness of the campus as a reason for neglecting their environmental duties. Others more simply litter since there is already litter everywhere else, and are adhering to a set trend, while other still, litter because they have too many papers on them at the time (Dasmann, 35). Members of the campus community also litter when they aim at a garbage can, miss it and out of laziness decide not to pic k up the straying litter. A huge portion of litter in the campus also comes from canteens and food joints in the campus. However prominent, paper waste is not the only form of littering seen around campus. Soda cans, beer bottles, cigarette butts, plastic bags, coffee cups and other such items equally commonly make up this list. In most cases, litter does not remain confined in one place (origin) as it can always move, thus escalating the problem. Litter from the campus often finds its way into the surrounding community, and vice-versa. Weather, wind and animals help move litter into planted gardens, waterways, parking lots, and so on, causing pollution in their wake. Litter can also create health risks by

Critical Analysis of Sustainabilty in Marketing Essay Example for Free

Critical Analysis of Sustainabilty in Marketing Essay Focus on sustainability has appeared on the face of the earth over the last ten years and a lot of books and articles are published on the topic of sustainability. Early on, John Elkington developed and promoted the concept of â€Å"Triple Bottom Line† in his book Cannibals with Forks: The Triple Bottom Line of 21st Century Business which was published in late 1999 (Creating a Sustainable Organization: Approaches for Enhancing Corporate value through Sustainability By Peter A. Soyka, Pg. 1) The concept of sustainability is transformed to cover three basic components known as the Triple Bottom Line which are complexly linked to one another: profits-it is the economical part that balances financial growth with awareness and concern for the social good and environmental stewardship; planet-it is the environmental part that safeguards and preserves the natural qualities of our ecosystem for the benefit and health of future generations; people-it is the social equity part that safe guards the benefits of opportunity and equality for every individual. See more: how to write a critical analysis essay step by step The growing importance of sustainable development establishes a significant and developing challenge for environmental economics and natural resources. This challenge is such big that if it is not measured and controlled then it will ruin the life of the future generations that’s the reason why every field now a days strive to work hard to have Sustainable Value Creation (SVC). The question arises what is sustainability, a more relevant answer is provided by The Brundtland commission (1987) which says to be sustainable is to meet the needs of the present without compromising the ability of future generations to meet their own needs. While this looks clear but if we observe it thoroughly and closely there are some complications and difficulties in it (Smart Green: How to Implement Sustainable Business Practices in Any Industry-and Make Money By Jonathan Estes page 6-8). The first problem which is a marketing problem is in the needs of the present and no one today knows of what level of needs we are talking about. The second difficulty is an ethical question that relates to the future and intergenerational justice, how we know what the needs of the future generations will be and how far do we look into the future? These two questions i.e. marketing and ethical must be explained much more clearly and  precisely than the definition of the sustainability suggests. The world economies currently face many challenges in the domain of public and commercial policy and one of the most crucial challenges they are facing is sustainable development. According to the projections of United Nations (UN) on population growth, the population of the world will most likely reach nine (9) billion people by the year 2050 with most of the growth taking place in emerging and developing countries. It is the commitment of UN to improve environmental and social performance associated with sustainable development. It seems that it is highly unlikely to achieve the goals set by the UN with current unbalanced consumptio n, marketing and production practices. KEY IDEAS OF SUSTAINABLE MARKETING: SUSTAINABLE CONSUMER BEHAVIOR Creating consumer demand for sustainable products and services is not an easy task because the consumers traditionally behave to maximize their own utility. Many consumers think that anything which is good for the entire society in the long term is always the best option for the individuals in the short term and unfortunately for most of the consumers the positive attitudes toward sustainable development is not shown in their actual consumer behavior and purchases. There are differences in what people say and what they actually do. Sustainable consumer behavior can be enhanced by positioning sustainable behavior with consumers’ self-interest and by making sure that this self-interest is understood and recognized thoroughly and can be acted upon (Encouraging Sustainable Behavior: Psychology and the Environment edited by Hans C.M. van Trijp page 3, 4). Consumers when they consume sustainably also behave in a way that shows or signals there superiority over others. Marketing efforts should be made to enhance sustainable consumption that leads to reduction in the trait of signaling instinct i.e. our inclination to signal to others that we hold valued traits. SUSTAINABLE MARKETING STRATEGY AND PRACTICE The objective of sustainable marketing is to include and combine the environmental concerns in the marketing effort; this means that if the consumers are given better, more complete and more concise information on the sustainable products offered to them this will drive more and more  companies to produce products and services that are good for the environment. Sustainable marketing can take the strategies of conventional marketing to promote sustainable products and services not only by labelling the green products but also from working with positioning strategies of product, promotion, price and placement and rigorously engaging in market creation by addressing a large number of customers. The company’s marketing strategy throughout the supply chain from product development to consumption should include sustainability in it. Many companies are focusing on the implementation of sustainable consumption; they are finding the ways to direct the people’s thinking to forthcoming challenges and problems by using different marketing and communication strategies that lead to sustainable consumption. Sustainable communication and marketing strategies can make the companies think of their long-term socio-economic influence and the long-term perspective of it; this will help the companies to tell the public about their future program without diminishing their present less environmental performance. EFFECTIVE SOCIAL MARKETING Effective social marketing is a community and pragmatic based approach; it brings very operative behavioral change. This approach has five steps i.e. prudently pick the behaviors to be promoted; identify the benefits and barriers which come with the selected behavior; form a strategy that uses the behavioral-change tools to understand these benefits and barriers; test the strategy on a sample of certain community; and evaluate the effect of the strategy when it is tested on a large scale (Design for Environment as a Tool for the Development of a Sustainable Supply Chain by Bevilacqua, MaurizioCiarapica,Filippo Emanuele Giacchetta, Giancarlo, pg 147). Social marketing is different from commercial marketing it takes into account the changes in behavior that contributes social gains while commercial marketing’s objective is to produce financial gains by selling products and services. There are five important areas where social marketing focuses very heavily and they are; communit y involvement, health promotion, environmental protection, financial well-being and injury prevention (Social marketing: A pathway to consumption reduction? Ken Peattie, Sue Peattie. Pg. 262-264) TRANSFORMATION OF TRADITIONAL MARKETING TO SUSTAINABLE MARKETING Marketing has now changed itself it has a sustainability feature in nearly all of the  marketing practices. It is now somewhat compulsory for the companies to consider sustainability in all of their strategic marketing practices and marketing mix. It is a very distinctive and objective task to integrate sustainability in the marketing strategy and at the same time it is not an easy task because marketing strategies are developed by taking into account the needs and wants of the costumers. Previously the companies only tried to fulfill the consumer demand whether it has an adverse effect on nature or environment but now more companies are forming sustainable marketing strategies that makes relationships with customers better by fulfilling their demands and results in good profitability of the company and have good impact on nature and environment. Paettie and Belz (2010) after years of research came up with the idea of 4C’s i.e. (Cost, Communication, Costumer cost and Costumer Solution) and tried to mold traditional marketing Mix i.e. 4P’s (Product, Price, Place and Promotion) into 4C’s (Evolution of sustainability as marketing strategy: Beginning of new era Vinod Kumar, Zillur Rahman, A. A. Kazmi and Praveen Goyal, pg 486-487). SUSTAINABLE MARKETING- CHALLENGES AND ISSUES Developing a sustainable marketing strategy is not an easy task because there are some issues and challenges that should be dealt carefully and prudently before going on with the strategy. The issue is what sustainability principles demand is that we need to conserve the resources and consume less of it and at the same time marketing principles demands to sell or produce more which means consume more natural resources (jones et al 2008). The challenge is how to balance this discrepancy and which means that sustainable marketing strategies should be developed that still result in profits but not creating negative impact on the society or environment. The process of arising of a problem and solving it is an ongoing process one may come up with an idea or solution to an issue but there would be some problems with that solution too (Charter et al 2006). A good thing of sustainable marketing is not only competitive advantage but it also gives rise to innovation and reduction in costs. CONCLUSION The Marketing concept now has redefined which was acknowledged only as a functional concept and this concept is now dying and losing its grip on the  world stage. Now the redefined concept of marketing is strategic business concept that is intended to attain sustainable satisfaction for the three main players or stakeholders i.e shareholders, the costumers and people in the organization. The concept of sustainability marketing strategy started from ecological issues has now come to discuss sustainability issues. A company may have a sustainable marketing strategy if it involves sustainability in its business practices especially the marketing practices. The companies have to resolve the traditional issues and challenges which come in the way of implementing sustainability in their marketing strategies and then it will be a win-win situation for both the costumer and company. It has now becoming an informal moral obligation for a company to be sustainable. In this new era marketing and in the future, the companies have to be sustainable to compete on the world stage.

Metal Health Support for Youth Depression

Metal Health Support for Youth Depression Introduction Feeling sad, unhappy, or down in the dumps occasionally is not unusual, however when these feelings outweigh a youths happiness or excitement it is concerning. Depression is a common and severe disorder amongst adolescences. Depression has lasting effects on an individuals feelings, thoughts, self-worth, behaviors, social relationships, physical functioning, biological developments, work productivity, and life fulfillment. It is a common psychiatric disorder that often affects adolescences and has been ranked as the fourth leading cause of disability and early death worldwide. Depression not only affects emotions but is a serious condition which makes coping difficult and leaves a person feeling sad most of the time. Feelings of sadness and low self-worth are overwhelming and can last for weeks, months or even longer for individuals (Beyondblue, n.d.).   Incorporating mental health programs into the lives of youth is valuable to send a message to individuals that depression is treatable, people can help, and that things can improve. Children and adolescents spend a considerable amount of time at school, and it is necessary for schools to offer mental health programs that include prevention and intervention services targeted at youth suffering from depression (Stallard, 2013). This paper will discuss the causation of adolescent depression, physical manifestations, educational supports, and professional supports.   Causation Everyone experiences depression differently and there is not an easy answer for why youth develop the condition, but there is a combination of reasons. It is a mental illness that significantly affects youth. Depression is more common amongst girls than boys but boys often find it hard to share their feelings (Beyondblue, n.d.). Some of the common causes of youth depression are the same as adults such as biological causes, stress, and trying life events. Other causes of youth depression include parenting, substance abuse, and low self-worth (Coleman, Walker, Lee, Friesen, & Squire, 2009). According to Mental Health America, depressed youth can have too much or too little of certain brain chemicals which also causes depression. Other sources of depression are having a family history of depression, side-effects from medications, and persistent negative thought patterns (Depression in Teens, 2016,).  Ã‚   It is normal for people to feel sad or discouraged at times because we all feel these emotions at some point due to various life events. Such life events like fighting with a friend, a breakup happening, getting a poor grade on an assignment or test, or the death of someone can all create feelings of sadness or disappointment. Non-depressed individuals experiencing these events and feelings manage to deal with the emotions and get past them with a little time and care. However, depressed people experience these events differently because the feelings last longer and affects not only the persons mood but their thinking too (Lyness, 2016,). Many things can change how we think, feel, and behave; however stressful life events can cause youth to develop depression. Symptoms might present with feelings of sadness, distress, and anxiety, however over time they become more intense and overwhelming. Prevalent causes of depression in youth are loss and grief, bullying, alcohol and drug use, low self-esteem and body image, discrimination, physical health problems, life events, family breakups, and loneliness. Stress is another common factor in an adolescent’s life and when young people are under stress, it can increase their likely hood of developing depression. At times problems can seem too big and overwhelming to solve, but the best thing adolescents can do is talk to someone. Youth who take steps and recognize how they feel are on their way to recovery (Andersen, & Teicher, 2008; Beyondblue, n.d.).  Ã‚  Ã‚   Physical Manifestations One in five youth suffer from clinical depression, and more than 25% of adolescents will experience a major depressive disorder by age nineteen. Depression is also prevalent amongst 1% of the population under age twelve, but between age fifteen to eighteen is dominant amongst 17% to 25% of youth. Depression is not an easy diagnosis amongst youth because they have different signs compared to adults. Moodiness amongst youth is common, but when it lasts for more than two weeks help should be sought. Adolescents are likely to be irritable without visible signs of sadness. On the other hand, depressed youth will have low school performance, withdraw from friends and activities, feel hopeless, lack enthusiasm and energy, overreact to criticism, have low self-esteem, lack concentration, feel restless and on edge, have a change in eating and sleeping patterns, develop problems with authority, and exhibit suicidal thoughts or actions. Young people feeling depressed have increased feelings of irritability, sadness, stress, anger, restless, and over analyze what is on their mind. Other feelings youth might experience are guilt, worthlessness, frustration, unhappiness, indecisiveness, and disappointment (Depression in Teens, 2016).   Adolescents experience more emotional and behavioral problems than do non-depressed youth. Young people who are depressed can have co-occurring disorders such as anxiety, difficulties paying attention and hyperactivity, aggression, substance use, and Post Traumatic Stress Disorder (PTSD) symptoms. Youth who are experiencing depression not only have personal issues, but their social relationships are affected too. Depressed adolescents feel unsupported by friends and adults. Youth also show more signs of a lack of interest in activities they find enjoyable, feel extremely sleepy throughout the day, have a decreased ability to think and focus, feel deeply saddened, and suicidal. Suicide unfolds with age, therefore before the age of ten it is rare for children to have suicidal thoughts or actions, but increases between the age of ten and fourteen, and rises ten times higher in youth ages fifteen to nineteen (Andersen, & Teicher, 2008).   Educational Support Implications Since depression is a common mental health diagnosis amongst youth, it is important to know depression screening is one possible method for managing depression. Then again, there are risk factors for screening youth. A few risk factors are testing is costly, it can cause harm to some people due to misdiagnoses and in proper treatment, and there could be false positive results if screening tools are not administered properly. Across the United States, screening programs have been implemented in some schools and medical settings. Screening is an early intervention to help detect signs and symptoms amongst youth who otherwise show none. Depression symptom questionnaires and small sets of questions are used for testing to identify individuals who may have current depression that has not been recognized (Thombs, Roseman, & Kloda, 2012).   Depression is not easy to determine amongst youth due to the different symptoms, on the other hand few children are identified and referred for treatment. Schools are natural and convenient setting for mental health prevention programs to be offered. Youth regularly spend a substantial majority of their time at school. Many adolescents who have depression have no contact with mental health services. Schools can provide universal programs to target all youth regardless of risk, or they can provide selective interventions which target selected groups with an increased risk. When providing a global approach schools can cover a larger population and mental health is less stigmatizing; however, the programs can result in smaller treatment effects. Programs can be appealing and have a significant impact on mental health if supported and implemented correctly (Stallard, 2013).  Ã‚  Ã‚   At school youth also need to be able to talk with a counselor or social worker about their feelings. They also need to be provided with adequate daily exercise, exposure to daylight, and healthier eating options. School personnel can teach relaxation skills to help increase sleep and decrease feelings of worry. Many adolescents find it beneficial to confide in and talk to a trusting adult. Educators can listen and show empathy, remind the youth that things can get better and that they are there for them, help them see things that are already good in their life, find enjoyable things to do, and give honest compliments and smiles. Youth need to be educated on how to manage sad feelings. In order to help youth gain positive coping skills, schools need to provide educational curriculum on eating healthy foods, getting the right amount of sleep, exercising, taking time to relax, and taking time to notice the good things in life (Lyness, 2016, August). Schools can be a common place for stu dents to see a mental health professional; therefore, it is important for schools to have effective school-based programs to address mental health issues in the schools. It is vital for schools to provide school personnel opportunities for training in recognizing youth depression. Classroom teachers have contact with students throughout the school day and are likely to see changes in students behaviors. Not only is it important to recognize depression in youth, but it is necessary to evaluate and treat depressed adolescents. School counselors, school nurses, school psychologist, and school social workers can help students experiencing depression, especially if youth are not receiving professional outside counseling. These school personnel are trained to recognize and plan for mental health issues in students and should be utilized to help students with depression. School mental health professionals can screen students for mental health, develop interventions and plans, provide prevention programs, and provide individual or group counseling. Although schools have resources, to be most helpful, schools should connect with resources outside of school (B eyondblue, n.d.; Stallard, 2013).  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Professional Supports Youth struggling with depression need immediate treatment because if left untreated it can lead to death. Some adolescents may refuse treatment; however significant adults in their life can seek professional help. Depressed youth should see a therapist to assist them in understanding why they feel the way they do and to learn how to use coping skills to handle stressful situations. There are individual counseling options available along with group and family counseling opportunities. When working with a mental health professional, youth may be presented with the possibility of medication to help feel better. Several factors contribute to youth depression, but prompt and appropriate treatment are critical in helping youth cope with depression. When working with a therapist young people can do psychotherapy, cognitive-behavioral therapy, interpersonal therapy, and medication (Depression in Teens, 2016). With the right care and treatment, depression can get better and easier to manage. Individuals who are depressed should not wait to get help because things can only get worse. Youth who feel depressed should talk to a parent or an adult and get the right help. A medical doctor can provide a checkup and look for symptoms causing depression. Different medical conditions that might cause depression include hypothyroidism and mono. Another resource for youth is to utilize a therapist or counselor to talk about his/her emotional state. Speaking to a counselor or therapist allows individuals to understand emotions, put feelings into words, feel understood and supported, builds confidence, increases problem-solving skills, helps change negative thinking, increases self-worth, and increases experiencing positive emotions (Lyness, 2016). Conclusion Youth depression is growing at a fast rate. When young people are feeling down, they can try to make new healthy friendships, participate in sports, a job, other school activities, or hobbies, join an organization, and ask a trusted adult for help. However, sometimes these will not help an individual, and they become depressed (Depression in Teens, 2016, December 08). Even though schools provide mental health programs for youth at risk, many students with mental health diagnoses are being untreated. In schools, it is common for school counselors, school nurses, school psychologist, and school social workers to provide mental health services to students. Schools are a safe place for youth to become educated positive, healthy ways to cope with stressful life circumstances. Depression can go unrecognized because people do not realize they are depressed, it might be misunderstood as a bad mood, or some people with depression have co-occurring mental health issues. Without recognition of a change in mood, thoughts, and behaviors many depressed adolescents will turn to unhealthy coping mechanisms such as alcohol, tobacco, and drugs; therefore, depression education for all individuals is essential (Depression in Teens, 2016).   References Andersen, S.

Analysis of the Doppler Effect

Analysis of the Doppler Effect Assignment 3: topics and themes in physics- oscillations and waves Doppler radar A Doppler radar is specialized radar that uses the Doppler Effect to produce data about an objects velocity at a given distance. Doppler radar works by bouncing microwave signals at the desired target and then listening to its reflection, then the returning frequency is analysed to see how it has changed from the original signal. This variation gives direct and highly accurate measurements of the radial component of a targets velocity relative to the radar. The Doppler effect (or Doppler shift), named after the famed Austrian physicist Christian Doppler who proposed it in 1842 and is the difference between the observed frequency and the emitted frequency of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and dulls from an observer perspective. When a wave with angular frequency ω and phase velocity c propagates in a medium, an observer moving with velocity v parallel to c experiences a shifted frequency ω1 = ω (1 − v/c) (1). They do not depend on the relative velocity as other circumstances do occur. Electromagnetic waves share with sound the same property which is propagation velocity. It is independent of the motion of the source . Einstein formulated his extended principle of relativity stated that all physical and electromagnetic forces should depend on relative velocities. From this he created Lorentz transformation. Sound vs. Light There are three differences between acoustical (sound) and optical (light) Doppler effects: The optical frequency change is not dependent on which is moving the source or observer either is it affected by the medium through which the waves are moving, but acoustical frequency is affected by these things. Optical frequency changes are affected if the source or observer moves at right angles to the line connecting the source and observer. Observed acoustical changes are not affected in such a situation. Applications of the Doppler phenomenon include the Doppler radar and the measurement by astronomers of the motion and direction of celestial bodies. Light itself travels at 186,000miles a second (, but unlike sound light doesn’t need to travel through a medium. Whereas sound cannot be transmitted into space light can be in the form of radiation and also a form of energy that is put through a vacuum. The Doppler effect of light is more commonly known as the relativistic Doppler Effect. The Doppler Effect In Astronomy In astronomy, the Doppler Effect was originally studied in the visible part of the electromagnetic spectrum. Today we can the see the use of the Doppler shift(Doppler effect) applies to all parts of the electromagnetic spectrum. Also, because of the inverse relationship between frequency and wavelength, we can describe the Doppler shift in terms of wavelength. Radiation is red shifted when its wavelength increases, and is blue shifted when its wavelength decreases. Astronomers use Doppler shifts to calculate very accurately at what rate stars and other astronomical objects are moving towards or away from Earth. For example the spectral lines emitted by hydrogen gas in distant galaxies is often observed to be considerably red shifted. The spectral line emission, normally found at a wavelength of 21 centimetres on Earth, might be observed at 21.1 centimetres instead. This 0.1 centimetre redshift would indicate that the gas is moving away from Earth at over 1,400 kilometres per second (over 880 miles per second). The red shift As an object moves further away from an observer the light waves emitted are affected by the Doppler Effect. In 1923, American astronomer and physicist Edwin Hubble (1889-1953) observed that the light waves from distant galaxies were shifted so much to the red end of the light spectrum that they must be moving away from the Milky Way, the galaxy in which Earth is located, at a high rate.(10) After these finding he then furthered his studies and came up with a mathematical formula in which he could determine how far away and at what rate they were moving away from the galaxy and how far towards the red shift. This formula is known as Hubble’s constant. From this a lot of other astronomers have come together and came up with the theory that the universe emerged instantly in a sort of bang, therefore coming amount the big bang theory. My research of galaxies the sun itself contains helium. This is proven as on the spectrum scale there are black lines in which the sun has absorbed light through the helium The Doppler Effect in aerospace Sonic booms, usually produced by airplanes passing through the sound barrier, are another example of the Doppler Effect. As a plane approaches the sound barrier the sound waves become increasingly compressed at the front of the plane. Pilots have also reported that they feel noticeable wall or barrier as they approach the speed of sound, and this is due to this intense compression of the sound waves. When the plane reaches the speed of sound, and passes through, it is said to go supersonic. There have been high speed photos taken of high velocity objects such as planes and bullets approaching, then breaking through the sound barrier. In these, the compression of the sound waves are clearly shown in the front, with the concomitant lengthening at the rear, just as would be expected by the Doppler Effect. Doppler Navigation System uses the Doppler effect to measure an aircrafts ground speed and heading. The Doppler radar functions by continuous measurement of Doppler shift and converting the measured values to groundspeed and drift angle. In early systems the aircrafts departure point was loaded into a navigation computer, which then converted the aircrafts heading and Doppler ground speed/drift inputs into a continuous display of aircraft position; this was then displayed as latitude and longitude, and/ or as distance to go along track and position left or right of track, in nautical miles. Aircraft navigation systems such as these are very important because they are key in getting the aircraft from one location to another safely. Doppler navigation is also one of the systems that air traffic controllers use, its allows then to see an aircraft’s exact heading, air speed and altitude. This allows the aircraft controller to give keep aircraft in clear and uncongested air which s ignificantly reduces the chances of in air collisions. DOPPLER RADAR The police also utilise the Doppler Effect in the form of Doppler radar to calculate the speed of passing car and to check whether they are obeying the speed limits. This technology is not only used by the police but also by meteorologists. The change in frequency experienced as a result of the Doppler effect is exactly twice the ratio between the velocity of the target (for instance, a speeding car) and the speed with which the radar pulse is directed toward the target. From this formula, it is possible to determine the velocity of the target when the frequency change and speed of radar propagation are known. The police officers Doppler radar performs these calculations; then all the officer has to do is pull over the speeder and write a ticket. The development in Doppler radar has also helped to helped to eliminate aviation crashes associated with microburst. A microburst is a very localized column of sinking air caused by a small and intense downdraft within a thunderstorm. The crash Delta Air Lines Flight 191 , which a microburst was the primary cause for the crash of the Lockheed L1011 Tri-Star was key factor in the push for developing microburst detection system. As a result of the crash, planes are now fitted with Doppler radar as standard. It allows pilots to prepare for microburst and allows then to increase power to the engines to stop the plane from crashing. The Doppler radar system of the plane is usually located in the planes ray dome. Meteorology Meteorologists use Doppler radar to track the movement of storm by detecting the direction and velocity of raindrops or hail, for instance, Doppler radar can be used to determine the motion of winds and, thus, to predict weather patterns that will follow in the next minutes or hours. But Doppler radar can do more than simply detect a storm in progress: Doppler technology also aids meteorologists by interpreting wind direction, as an indicator of incoming storms. Meteorologists use a similar principle to read weather events. In this case, the stationary transmitter is located in a weather station and the moving object being studied is a storm system. This is what happens: Radio waves are emitted from a weather station at very specific frequency. The waves are large enough to interact with clouds and other atmospheric objects. The waves strike objects and bounce back toward the station. If the clouds or precipitation are moving away from the station, the frequency of the waves reflected back decreases. If the clouds or precipitation are moving toward the station, the frequency of the waves reflected back increases. Computers in the radar electronically convert Doppler shift data about the reflected radio waves into more useful pictures which show wind speeds and direction. Doppler radars are also a lot more sensitive to movement of targets in general, whether they are moving towards or away from the radar site which things such as birds, insects, or just clouds when they are operated in certain modes. Doppler radars measure a targets velocity, which both is the speed of movement the direction that its moving. These types of radars allow meteorologists to see a lot of the in detail movements that go on inside thunderstorms, this then allows the meteorologists to predict how those thunderstorms will behave in the future. Doppler Echocardiogram A traditional echocardiogram uses sound waves to produce fairly accurate images of the heart. In this procedure, a radiologist uses a transducer to transmit and receive ultrasound waves, which are reflected when they reach the edge of two structures with different densities. The image produced by an echocardiogram shows the edges of heart structures, but the down side it cannot measure the speed of blood flow as it makes its way through the heart. In a Doppler echocardiogram, sound waves of a certain frequency are transmitted into the heart. The sound waves bounce off blood cells moving through the heart and blood vessels. The movement of these cells, either toward or away from the transmitted waves which then results in a frequency shift that can be measured. This helps cardiologists determine the speed and direction of blood flow in the heart which is the most significant difference between the traditional echocardiogram and a Doppler echocardiogram. Transverse and longitudinal waves A transverse wave is a moving wave that consists of oscillations occurring at right angles to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. For transverse waves in matter the displacement of the medium is at 90 degrees to the direction of propagation of the wave. A ripple in a pond and a wave on a string are easily visualized forms of transverse waves. Examples of transverse waves include S (secondary) waves, and the motion of the electric (E) and magnetic (M) fields in an electromagnetic plane wave, which both oscillate perpendicularly to each other as well as to the direction of energy transfer. Conclusion In conclusion this reports through my many hours of research, talks in detail about the history and the useful applications of it. Aircraft and aerospace engineering as they use Doppler radar is a very interesting and a wide range of applications and I have toughly enjoyed researching about it especially since these are topic areas which i am particularly interested and other practical uses with the speed guns used in the police force and also the sirens on the motor vehicles. The application of the Doppler Effect and its applications in aerospace are a very interesting subject and something which i very much look forward to looking and working on in am going into university.

Personal Narrative - A Hole In My Left Shoe :: Personal Narrative Writing

A Hole In My Left Shoe I have a hole in my left shoe. It’s on the inside of my left shoe, and it’s been there since the first week I had these shoes. It doesn’t grow or change, because the circumstances that begot it do not grow or change. It’s there because when I sword fight I drag that foot as part of my footwork. This hole in my shoe is a constant thing in my life. Even when I get a new pair of shoes it will still be back there within a week. Look closely at this hole and you can see into it, into me. You can see a story that begins several years ago. I can see him coming from a distance; we stand in a wide expanse of grassy field in the upper reaches of the North Carolina mountains. The boy is a friend of mine; his name is Lucuse, and I’ve known him for a week and already we have the makings of life long friends. But right now we are enemies of the most mortal kind. We circle each other, a stick in each hand, our sabers, and weapons of choice. We size one another up. He is much bigger than me in all aspects except our height, which I take him by scant inches. I’m faster, and he knows it, but if we should get into a lock and are forced to rely on force he knows he will win. Our plans formulated we begin, a slash, a stab. The world around us blurs; it’s still there, but only as a memory. All that exists is a fog, a fog and my opponent. I see him in his entirety, I see the way his body moves, how each piece of him works to form his bid for my demise. I’m aware of myself; I can sense every movement that wo uld at one time have been taken for granted. Now each step is a chapter in a novel that I can’t put down till the end. The adrenalin pounds in my mind as my opponent strikes at me trying to find a hole in my defense. It is in this feeling that I find true happiness for the first time in my young life. That was then and this is now, and I’m a different person now than I was then.

Internet Users Should Practice Self Restraint :: Argumentative Persuasive Argument Essays

Internet Users Should Practice Self Restraint The generation of the 90s, the information generation, or better yet the generation-X, has been plunged into a world of computers. To survive, each individual must have knowledge of and feel comfortable with the computer; a scary word and a frightful system to those not acquainted with it. The Internet is the essential application that needs to be grasped. It is the information network of the future. However, the variety of people using it is as vast as the world around. Hence, this is a community that is truly the world's largest melting pot, bringing people together from all ends of the world. The Internet becomes a social structure and with any social structure, it has its problems. Today, one of the rising problems with the Internet is that most people have their entire lives on the system; hence they are potentially exposed to all types of criminals. All addresses, phone numbers, credit histories, and sometimes even photographs can be found through the net. As in the real world, even in the Internet, women seem to be in a vulnerable position because they are the least protected by stalkers, kidnappers, murderers and psychopaths in general. A point, in fact clearly demonstrated in the movie "The Net", starring Sandra Bullock who was chased down by the government through the Internet. Although, many times the individual can remain anonymous and separate from all biases and prejudices, they still have all their information stored for it to be pried into by any clever hacker. Another vulnerable group constitutes children; lawmakers and concerned citizens worry about them being exposed to "adult material" on the Internet. At times it is as if their first priority becomes protecting these children from pornography, offensive material and often times just extreme view points. A downside to focusing so much attention on pornography is that often people are just fueling the curiosity of those they are aiming to protect. Although regulating the Internet for children is beneficial, often the regulations also encompass college students, who need a free hand to travel through this medium. This protection from "adult material" often restricts the learning process and prevents them from fully experiencing the Internet. Recently, lawmakers have attempted to set guidelines for the Internet. This poses a problem in itself because the Internet is a worldwide system. The rules that are placed must be agreed upon across the globe.
