We will write a custom essay sample on Tell Tale Heart Essay or any similar topic only for you Order Now The protagonist loved the old man, eliminating motives that might normally in spire such a violent murder. As he proclaims his own sanity, the narrator fixates on the old man’s vulture. â€Å"It was open wide, wide open and grew furious as gazed upon it. Saw it wit h perfect strictness all a dull blue, with a hideous veil over it that chilled the very mar row in my bones; but I could see nothing else of the old man ‘s face or person: for I had directed the ray as if by instinct, precisely upon the damned spot. † The narrator reduces the old man t o the distinctive blue of his eye in obsessive fashion. He separates the man from his â€Å"Evil Eye† so he can spare the man the burden of guilt that he attributes to the eye itself. The narrator FAA ills to see that the eye of the old man is a fundamental part of his identity that cannot be isolate d as the narrator abnormally imagines. As a result of his warped sense of reality, the narrator obsesses over the low beats of the man’s heart, yet shows little concern about the man’s shrieks, which are loud enough to attract his neighbor’s attention and draw the police to the scene of the crime. Through hoot the story, he explains that he is not mad, but ironically, he is the opposite of this, as he strut eagles to comprehend his own mind. The narrator’s paranoia and guilt make it mine NT that he will give himself away. The police arrive on the scene to give him the opportunity to be tray himself. The more the narrator professes his own calm manner, the more he is unable to e cape the beating of his own heart, which he mistakes for the beating of the old man’s heart. As he confesses to the crime in the final sentence, he addresses the policemen as â€Å"villains,† indicating g his incapability to distinguish between their real identity and his own villainy. The internal conflict within the story is disguised as external conflict, through t he way that Poe describes the struggle of man versus man and man versus self.

Television Influence Essays (1329 words) - Behavior, Human Behavior

Television Influence Television influences behaviors, social attitudes and physical health especially in children. Children today spend more time watching television than on any other single leisure activity. In fact, studies have shown that "the average child spends more time in front of the television than in school" (Clarke and Kurte-Coastes, 1997). There are a variety of influences that children gain from watching too much television. The impact of violence on children is a major issue, as well as the impact of stereotypical views, such as sex roles. Health can also become a problem for children who spend excessive amounts of time in front of the television. There are, however, alternatives to these problems. Parent, schools and the governments need to take control and monitor children and television. After all, television was once used as an educational tool it has only recently become a babysitter. The effect of violence in television has been debated for many years. In a recent study, Strasburger and Donnerstein (1999), suggests that there is a positive correlation between violence viewed on television and aggressive behavior in children. The way television violence is portrayed encourages children to learn aggressive attitudes and behaviors. For example most violence on television is glamorized by using a "good" character that is likely to be perceived as role model to initiate violence. This gives children the impression that violence is justified, desirable, and painless. Violence on television also increases fear or gives children the wrong impression about the world. Many children have a hard time making distinctions about what is real and unreal. Therefore, they begin to believe that the television depicts violence in the "real world." The bottom line is, "children learn their attitudes about violence at a very young age, and once learned, the attitudes tend to be life-long" (Strasburger and Donnerstein, 1999). Television also encourages stereotyped opinions on topics such as sex roles. Research shows that children who spend more time watching television tend to think that both women and men have specified roles in the world (Kent and Moy, 1999). Television usually portrays women as passive and weak compared to men who are usually depicted as strong and dominant (Steinberg and Kincheloe, 1997). This gives children a clear impression of what is expected of them in society. It insists that they too should act this way because it is, after all, what society views appropriate. Television even pushes children toward specific sex role using toys. Most toy commercials, for example, even insist that some toys are only for girls while others are only for boys. Children are very rarely encouraged to play with toys that are known to be for the opposite sex. For example, boys aren't aloud to play with dolls and girls aren't aloud to play with trucks. Television also emphasizes the importance of physical beauty. Stress is placed on looking a certain way, whether it is having the right clothing or being a certain weight. These are influences that children take very seriously considering that most children want to be the "popular" one in school. Take the Mighty Morphine Power Rangers, for example, the female good rangers are viewed typically as beautiful and perfect. The female villains are typically viewed as "repulsive" and are teased. In most schools this is the " kind of schoolyard harassment to which unpopular girls are subjected" (Steinberg and Kincheloe, 1997). Television also takes a major toll on a child's physical health. Obesity in children is rising and television is being credited in playing apart. One reason may be that children are spending less time on physical activities, such as, swimming and riding bikes (Vecchine, 1997). Evidence also shows that children like to snack while watching television, which can add to the weight especially for those children who do not do much physical activity. Commercials on television also play a part in weight gain among children. Commercials tend to enhance a child's craving for the food products being advertised which persuades children to buy their food. In most cases the food advertised on television is high in calories and fat, which adds weight (Anonymous, 1999). Although television influences many children all over the world there are alternatives to the problem. Starting at home parents need to be aware of what their children are watching, as well as how many hours are spent watching television. More importantly parents need to take time to watch and discuss the programs with their children. (victor stasburger and edward donnerstein, 7). This allows for the children, especially the smaller ones who have a hard time differentiating reality form fiction,

The History and Origin of Aerosol Spray Cans

The History and Origin of Aerosol Spray Cans An  aerosol  is a  colloid  of fine  solid  particles or  liquid  droplets, in the air or another  gas.  Aerosols can be natural or artificial.  Frederick G. Donnan  presumably first used the term  aerosol  during  World War I  to describe an aero-solution, clouds of microscopic particles in the air. Origins The concept of an aerosol originated as early as 1790 when self-pressurized carbonated beverages were introduced in France. In 1837, a man called Perpigna invented a soda siphon incorporating a valve. Metal spray cans were being tested as early as 1862. They were constructed from heavy steel and were too bulky to be commercially successful. In 1899, inventors Helbling and Pertsch patented aerosols pressurized using methyl and ethyl chloride as propellants. Erik Rotheim On November 23, 1927, Norwegian engineer Erik Rotheim (also spelled Eric Rotheim) patented the first aerosol can and valve that could hold and dispense products and propellant systems. This was the forerunner of the modern aerosol can and valve. In 1998, the Norwegian post office issued a stamp celebrating the Norwegian invention of the spray can. Lyle Goodhue and William Sullivan During World War II, the U.S. government funded research into a portable way for servicemen to spray malaria-carrying bugs. Department of Agriculture researchers, Lyle Goodhue and William Sullivan, developed a small aerosol can be pressurized by a liquefied gas (a fluorocarbon) in 1943. It was their design that made products like hair spray possible, along with the work of another inventor Robert Abplanalp. Robert Abplanalp - Valve Crimp In 1949, 27-year-old Robert H. Abplanalp’s invention of a crimp on valve enabled liquids to be sprayed from a can under the pressure of an inert gas. Spray cans, mainly containing insecticides, were available to the public in 1947 as a result of their use by U.S. soldiers for preventing insect-borne diseases. Abplanalp’s invention made of lightweight aluminum made the cans a cheap and practical way to dispense liquids foams, powders, and creams. In 1953, Robert Abplanalp patented his crimp-on valve for dispensing gases under pressure. His Precision Valve Corporation was soon earning over $100 million manufacturing one billion aerosol cans annually in the United States and one-half billion in 10 other countries. In the mid-1970s, concern over the use of fluorocarbons adversely affecting the ozone layer drove Abplanalp back into the lab for a solution. Substituting water-soluble hydrocarbons for the damaging fluorocarbons created an environmentally friendly aerosol can that did not harm the environment. This put the manufacture of the aerosol spray can products into high gear. Robert Abplanalp invented both the first clog-free valve for spray cans and the Aquasol or pump spray, which used water-soluble hydrocarbons as the propellant source. Spray Paint in a Can In 1949, canned spray paint was invented by Edward Seymour, the first paint color was aluminum. Edward Seymours wife Bonnie suggested the use of an aerosol can be filled with paint. Edward Seymour founded Seymour of Sycamore, Inc. of Chicago, USA, to manufacture his spray paints.

Food security in Eritrea Essay Example | Topics and Well Written Essays - 1500 words

Food security in Eritrea - Essay Example Eritrea is a sovereign state, which has been faced with numerous cases of conflict within itself and with its neighbours, especially Ethiopia, due to border demarcation issues, a factor which has resulted to internal displacement of people. Reports indicate that more than 10000 out of the original 70000 internally displaced persons still live in temporary camps, waiting to be resettled by the government (Tesfa, 2008). Apparently, this has been one of the major factors contributing to food shortages due to the fact that these people have no cultivatable land as the war pushed them out of their homes and as such, they can only depend on aid from well wishers and the government. It is estimated that more than 2 million people are affected by food insecurity, translating to approximately 40% of the total population (Tesfa, 2008). The fight for freedom, which lasted for approximately 30 years, left the country in a state of destruction especially in the agricultural sector. This is due to the fact that most of the lands which could be used for farming are littered with unexploded ordinances, which pose a security hazard to the farmers (Rena, 2007). In this context, any person trying to cultivate in these lands risks the possibility of triggering the explosion of land mines, which were buried during the war, but failed to explode. Tensions that continue to exist between Ethiopia and Eritrea have contributed to more installation of these landmines as a defensive mechanism at the expense of the farming communities (Zwi, 2005). The temporary security zone, which is considered to have been the most productive agricultural land measuring approximately 25km2 remains unutilized as a result of these landmines, which have kept away more than 50000 inhabitants, who were displaced by the war, regardless of the fact that n o more fighting takes place in this area (Zwi, 2005). With these developments, food production is deemed to remain low and as such, more people will continue to be affected by extreme hunger. This is also due to the fact that the government has continued to spend a lot of the already scarce resources to finance and facilitate the war with Ethiopia. For instance, it is estimated that more than 300 000 men and women are serving in the army instead of letting them engage in farming activities (Gebre, 2009). Human resource in the agricultural sector is a crucial necessity since activities such as cultivation, planting, and weeding as well as harvesting among others requires to be done in order to guarantee quality harvest. In Eritrea, this has not been the case as it has been observed that there have been limited human resources hence high labour costs. As earlier stated, poor diplomatic relations between the country and its neighbours, i.e. Ethiopia and Sudan, have led to the closure o f the respective borders. This means that no movement is allowed in and from the country, which has continued to impact the economy negatively. It is true to say that if this was not the case, citizens of these nations would have had a chance to interact economically through trading in imports and exports thereby increasing the amount of foreign exchange as well as revenue collected

GPS Systems in police patrol Essay Example | Topics and Well Written Essays - 250 words

GPS Systems in police patrol - Essay Example In addition, there is advantage of the GPS in terms of response time or arriving at a disclosed vicinity immediately, especially in emergency situations. For instance, a patrol vehicle that is located in a particular street in New York would be able to respond as soon as possible when an emergency call to address burglary or criminal activities in that street is reported. Through the GPS the police officers would immediately locate and respond, as required. 2) Explain the value of Automated Vehicle Locators (AVL) in police patrol vehicles from the point of view of a police dispatcher or supervisor. AVLs in police patrol vehicles are defined as â€Å"a device that makes use of the Global Positioning System (GPS) to enable a business or agency to remotely track the location of its vehicle fleet by using the Internet. These devices combine GPS technology, cellular communications, street-level mapping, and an intuitive user interface, with the ostensible goal of improving fleet management and customer service† (Tech Target par. 1). Therefore, from the point of view of a police dispatcher or a supervisor, AVLs provide them with the ability to immediately locate the whereabouts of these police patrol vehicles at all times and assist them in the following examples: monitoring purposes to determine if the patrol vehicles are in areas where they are supposed to be; and in changing their routes or for re-routing purposes, as immediately

Human Factors in Aviation for Pilots

Human Factors in Aviation for Pilots Human Factors in Aviation for Pilots Introduction The term â€Å"human factor† belongs to the wide range of matters affecting how people achieve tasks in their non-work and work environments. The commercial aviation industry has recognized that human error causes most aviation incidents and accidents rather than mechanical failure. If interpreted intently, human factors are often deemed synonymous with maintenance resource management (MRM) or crew resource management (CRM). Human factors involve collecting information about human limitations, ability and other qualities and applying it to machines, tools, tasks, systems, environments and jobs to produce comfortable, safe and effective human use. Human factors are devoted to better perception of how humans can most efficiently and safely be combined with technology. That perception is then translated into training, design, procedures, or policies to help humans work better. (GRAEBER, 2014) In spite of rapid gains in technology, humans are ultimately accountable for guaranteeing the safety and success of the aviation industry. They must continue to be flexible, knowledgeable, efficient, and dedicated while exercising good judgment. In the meantime, the industry continues to make main investments in equipment, training, and systems that have a long-standing implication. Human factors cover the knowledge of comprehending the human capabilities, the application of this knowledge to the development, design and exploitation of systems and services, and the art of guaranteeing successful application of human factor values into the maintenance working environment. Furthermore, human factors experts participate in examining operational safety and developing tools and methods to help operator better handle human error. These duties require the experts to work closely with safety experts, engineers, training and test pilots, mechanics and cabin crews to efficiently integrate huma n factors in the designing of airplanes. Human Factors in the Ground Environment Before understanding the importance of human factors we must know the term â€Å"PEAR†. It reminds the four important facts for human factor programs: People, Environment, Actions and Resources. The Aircraft Electronics Association accepts PEAR as an outstanding way to recall key concerns for a human factors program. There are as a minimum of two environments in aviation maintenance; physical work place and organizational environment. There is the physical work place in the hanger, on the ramp or in the shop while organizational environment exist within the company. A human factor should pay attention to both environments. The physical environment includes ranges of humidity, temperature, lightening, cleanliness, noise control, and workplace design. Companies must accept these conditions and collaborate with the workforce to either change or accommodate the physical environment. It takes a cooperate assurance to address the physical environment. This physical workplace covers the topic â€Å"Resources† of PEAR when it comes to providing coolers, portable heaters, clothing, lightening and task design and workplace. The second environment is organizational one. The significant factors in an organizational environment are usually related to communication, cooperation, mutual respect, shared values of the company, and their culture. An excellent organizational environment is progressed with communication, leadership and shared goals associated with profitability, safety and other key factors. The best companies support and guide their people and promote a culture of safety. We consider environmental matters as critical as other features in PEAR. . (Johnson, 2007) Aviation safety relies deeply on maintenance. When it is not done properly, it contributes to a major proportion of aviation incidents and accidents. Some examples poor maintenance are missing parts, parts installed incorrectly, and required checks not being performed. The errors of an aviation maintenance technician (AMT) can be more challenging to detect as compared with other threats to aviation safety. A lot of times, these errors are present but not visible and have possibility to remain hidden, affecting the harmless operation of aircraft for larger period of time. AMT’s tackled with many human factors unique within aviation. Most of the time, they are working in the early morning or in evening hours, in restrained spaces, and in mixture of unfavorable humidity/temperature conditions. The work can be physically tiring; it also needs attention to detail. AMTs usually spend more time on preparing for a job than actually practicing it out. Key element of all maintenance wor k is a proper documentation, and AMTs usually spend more time revising maintenance logs than they do presenting the work. Mechanical components in aircraft maintenance engineering have boundaries; technicians also have some limitations and limited capabilities when we look at the maintenance engineering system. For example, rivets used to fasten aluminum skin to fuselage that can bear forces acting to pull them apart. These rivets will ultimately fail if sufficient force is applied to them. The exact range of human limitations and capabilities are not clear as the performance range of electrical or mechanical components but the same rules apply in that human functions which is likely to damage and ultimately fail under certain conditions like stress, tensions etc. Human factors understanding can lead to enhanced quality, an environment that guarantees continuing aircraft and worker safety and a more responsible and involved work force. More precisely, the reduction of minor mistakes can provide appreciable benefits including fewer missed deadlines, cost reductions, reduction in injuries, reduction in maintenance errors and also reduction in warranty claims. Human factors in the Airborne Environment (flight desk, cockpit, formation) Men already learn how to construct wings or airplanes, which when propelled through the air at maximum speed, will not only withstand the weight of the engine, but also of the wings themselves, and of the engineer as well. Men also learn how to build screws of adequate power and lightness to drive these airplanes at sustaining speed. Inability to steer and balance still become challenging for students and have flying problems. When this feature has been controlled, the era of flying machines will have reached, for other problems are of lesser importance. (Kantowitz, 2011) Working with an aircraft in the Performance Based Airspace (PBA) will be extra challenging for the flight crews who have only worked in controlled airspace. But in real, only somewhat more challenging rules like Visual Flight Rule (VFR) are applied. The flight crew will have to handle more tasks, an arrival of basic separation responsibilities, have complete responsibility for all forms of situational awareness like mode awareness and traffic, possible greater workload under several conditions like severe weathers. To evaluate the necessary information needs of the flight crew to achieve the airborne self-separation task and to regulate the level of automation, it will be essential to study the following sub tasks; Conflict detection; Conflict privations; Traffic monitoring; Re-planning; Conflict resolution; Inter-traffic/traffic-FOC communication. It becomes clear that today’s conventional airline operations possible do not offer the information to examine the above tasks. It is, though, assumed that the flight crew will demand the high quality ergonomically planned navigation and traffic information and in various circumstances may require to be aided by some level of automation and maybe through some decision support tools. Presently flight crews use the TCAS (Traffic Collision Avoidance System) instead of ATC (Air Traffic Control) and to help them attain a minimum level of traffic situational awareness. But in today’s operational environment, TCAS information will not be enough. A CDTI (Cockpit Display of Traffic Information) system will possibly be a better system to help the aircrew to maintain and develop a high level of traffic situational awareness by offering basic data about speed, position and provide information of future state of aircraft in the neighborhood. The important requirement will possibly b e to aid the crew in the detection, prevention and resolution of an important conflict. In this area, it is assumed that the aircrew will be in a controlling position. The revealing of imminent collisions will be automated and will be implemented in the background. The crew will be warned in situation of imminent conflicts along with numerous solution strategies, which are supposed to be filtered and sorted for the crew by using various criteria (e.g., time/fuel optimization, wind and weather criteria, passenger comfort, etc.) to elect for the best solution in the given situation. The aircrew will have the probability to modify different factors of the maneuver (e.g. waypoints, aircraft speed, altitude) according to their requirements and own judgment of the situation. (International, 2007) Improvements One of the major risks a pilot faced is the unawareness of existing problem. This situation indicated as a loss of situational awareness. Loss of situation awareness is like danger is everywhere and you are pleasingly unaware of it. Loss of situational awareness can be initiated by somewhat as simple as inattention. A pilot is unaware of the mid-air collision curse because he or she hasn’t been concentrating in maintaining a traffic watch. A pilot is not aware of refueling of the piston engine aircraft that either jet fuel has been loaded into fuel tanks or not. A pilot is careless during the pre-flight examination that a poor gas seal and heavy rains put hazardous quantity of water in the fuel tanks. A pilot must have situational awareness to tackle any of the above dangerous situations effectively and efficiently. A pilot initially creates situational awareness through applied crew management skills and through trainings. Situational awareness also includes establishing targ ets and goals for a particular flight. Once established, it can be maintained by examining of clues to its possible loss. False assumptions are also cause of flight crews’ problems. It can include great expectations, problematic fixations, ignoring bad news, and intense situation of pilots in case of stress. These problems must be reducing to improve environments of aircraft organization. Cockpit stress management plays an important role in airborne environment. In case of any emergency, pilot must be clam, think for alternatives, choose one and then act on it. A pilot must avoid fear and panicking as they are our greatest enemies during emergencies. Don’t wait to announce any emergency until it’s too late for you to handle the situation. A pilot must immediately ask ATC for help. Lots of ground resources can be available for help. If any error occurs because of a pilot, he must forget about that and concentrate on the job at hands. A focus is must, think of an alternative plan and work on it immediately. Use of checklists can prevent as much as 70% of all the accidents which occur because of pilot primary errors. Cockpit stress management procedure can also be accomplished by using checklists instead of relying on memory of pilots only. Hypoxia is a deceptive problem in aviation. It occurs when body cell receives very less oxygen because of altitudes. Its consequences creep up on pilots without their realizing it. A pilot must be aware of how to handle this situation. The way of pilot to perform their job, the manner they cooperate with other crew members, the manner in which they use all available resources and many other details related to human presentation, will have deep effect on the manner in which they fly the airplane. A pilot must undergo a proper professional training in the area of human factors to improve their performance in all the aspects. Crew co-ordinations must be efficient and the monitoring and assignments of duties of all assigned crewmember must perform their jobs effectively. Communications occur between crewmembers related to flying tasks must not be vague, indefinite or unclear. Summary Human factors and its engineering feature involve the usage of knowledge about human limitations and capabilities to design a technological system. Human factor engineering also relates to personnel selection, training, procedures and many others. Humans can also fail to function appropriately in various conditions. Human can face physical fatigue, affected by the cold, can break bones in accidents in workshops etc. Mentally humans can make mistakes, have restrained powers, and can make poor judgments due to lack of knowledge and skills. Furthermore, human performance is also influenced by emotional and social factors. Therefore proper training of aircraft maintenance technicians is required to full all the features of human factors. The aircraft maintenance technicians are the main part of the maintenance system. It is thus very necessary to have knowledge of mental processes function and different parts of body and also the understanding of performance limitations that can affect the work. An essential part of the operational efficiency is continues improvement in flight crew training and in designs and procedures. Study of commercial airplane and human performance interfaces leads to reduce accidents and at the end increases flight safety. The flight deck human factors are researched which include measurement of flight performance and risk, impact of advance technologies, assessing controller pilot information transfer, determining the consciences of stressors on human performance, recognizing human factors included in incidents and accidents, analyzing the effects of tasks design on pilot performance. Human resources perform aerospace research on organizational and individual issues related to human factors. Research areas included designing of cockpit management programs, effective use of trainings related to human factors, recognition of human factors linked with maintenance- related aviation incidents and accidents and with aircrew Bibliography GRAEBER, C.
