Security Guard free essay sample
A security guard (or security officer) is a person who is paid to protect property, assets and people. Security guards are usually privately and formally employed personnel. Often, security officers are uniformed and act to protect property by maintaining a high visibility presence to deter illegal and inappropriate actions, observing (either directly, through patrols, or by watching alarm systems or video cameras) for signs of crime, fire or disorder, then taking action and reporting any incidents to their client and emergency services as appropriate. Since at least the Middle Ages in Europe, the term watchman was more commonly applied to this function. This term was carried over to North America where it was interchangeable with night-watchman until both terms were replaced with the modern security-based titles. Security guards are sometimes regarded as fulfilling a private policing function. Chapter 1 The Security Guard is the person who is guarding and protecting either facility or people.

Most of the time they are taking care of the order and protecting the facilities from anyone who want to enter to the place without any permission so they will stop the person and ask for the reason before let him or her to enter the place, also sometime they will not allow anyone to enter unless they get the order from the manger or the chief directly then the pass will be granted. Moreover, the security guard is given the work and orders from the manager or the admin person who is in charge of them to take care of the organization or the building by moving around the place for checking or whatever there is any suspicion thing should be reported or take an immediate action. In addition, some places require from the security guard to guide the visitors where to park their cars and in what position all this to control the safety in that place and to avoid whatever danger could happen. Also some places require from all the visitors to register their names, positions, date/time and where they are going so they will be provided with a visit card so they can enter. On the other hand, some places they do physical checking before entering like checking the bag or the pockets if itââ¬â¢s necessary and if there is more than one person sometime they will allow only one to enter not all of them. All of this is because of the importance of security and it is different from one place to another place depending on what is the requirement needed for the security. With most of the security guards or the security company should take a standard training that can make them fit and ready to take the position of security guard because if it is not done then it will cause a lot of problems and security issues for everyone due to not enough training which is required for such a position. Finally, the security guard position need a lot of things so he can do his work in a proper way so, he will need other equipment like for example security camera, a phone or a mobile, a uniform to be recognized and many other things which will help for the work to be done in a professional way because mistakes in this work is dangerous. Chapter 2 There is a lot of advantages of having security system and also security guards. By having the security guards we can be safe in different ways like: â⬠¢ Money saving â⬠¢ Assets and property protecting â⬠¢ People safety â⬠¢ Preventing more damage if there is an accident If something happen like if someone want to break in or want to steal from some place then the security guard make it very difficult or even stop it from happing, while if the security guard not available then it will be very easy to break in to any place and steal or even make the business in lose. Moreover, it is very important to have security guards as they can reduce the risk, as if there is a fire they will give the proper guidance to the people where to go, moving important thing to a safety place and try to protect whatever is possible until the firemen are arrived then provide them for whatever they want until they put off the fire. Also the security guards they not only for protecting places or people but also to provide information or guidance to anyone who ask or someone is lost and he donââ¬â¢t know where to go. On the other hand, they can be as the source of the needed information especially when there is no one available at the place like the holidays or late night. When a place is a having the security guards with their system it is appearing to be more professional rather than any other place which they donââ¬â¢t have the security guards system because we can observe that anyone can just be there without anyone can notice and that because everyone is busy with their work and there is no time to check for anything except it is an emergency then all they will stop to work. Chapter 3 The difficulties that the security guards are facing with their work can be like: â⬠¢ Having a small pay or salary â⬠¢ Ignorance â⬠¢ Lack of opportunities â⬠¢ Blaming from others A lot of pressure In this kind of profession the security guard can work but with small salary which they receive from the companies or the places for the services that they provide, it is not all of them but most of them because in some other places or organization they pay very well for the security guards but itââ¬â¢s not all because the majority is a small pay. More over, for the services and for their protection that they provide they donââ¬â¢t get a lot of attention from others either the visitors or the responsible people in the place of work or even outside the place of work. In addition, this kind of work have a lack of opportunities of growing or to be in better position and this can be from less amount of training or even education which is helping a lot when someone want to improve. Also there is some time when the security guards get all the blaming from others for something even itââ¬â¢s not their mistake but they keep getting this blaming like why you did not do this and that while it is not listed in his agenda to do so. When something happen at that time they will remember the security guards but if there is nothing happening no one even thanking them or even talk to them and appreciate of what they are doing. On the other hand, the environment which the security guards are performing their duty could be very bad for them in terms of their health and the mentality because they can work in extremely hot or cold places or sometime dangerous places, also the place of work could be very good but they can get a lot of pressure and be strict on them from the management which could lead to negative behaving. Conclusion For now we know the importance of the security guards, availability and the needful that they have. Even though they are facing problems and difficulties but for them to be around it is a must especially for certain places. We need them among us for protection, safety and to be as a guide, whenever we be in a position which is unsafe or in a worry we will remember the security guards and ask for their protection or a solution for different matters. So this profession is like any other important profession in our life.

Gold is usually alloyed to increase its strength. Pure gold is measured in troy weight, but when gold is alloyed with other metals the term karat is used to express the amount of gold present. Common Uses for Gold Gold is used in coinage and is the standard for many monetary systems. Ità is used for jewelry, dental work, plating, and reflectors. Chlorauric acid (HAuCl4) is used in photography for toning silver images. Disodium aurothiomalate, administered intramuscularly, is a treatment for arthritis. Where Gold Is Foundà Gold is found as the free metal and in tellurides. It is widely distributed and almost always associated with pyrite or quartz. Gold is found in veins and in alluvial deposits. Gold occurs in sea water in the amount of 0.1 to 2 mg/ton, depending on the location of the sample. Gold Trivia Gold is one of the few elements that can be found in its native state.Gold is the most malleable and ductile metal. One ounce of gold can be beaten out to 300 ft2 or stretched into a wire 2000 kilometers long (1 à ¼m thick).The melting point of gold is an assigned value, which serves as a calibration point for the International Temperature Scale and International Practical Temperature Scale.The gold ion in the 1 oxidation state (Au(I)) is called the aurous ion.The gold ion in the 3 oxidation state (Au(III)3) is called the auric ion.Compounds containing gold in the -1 oxidation state are called aurides. (Cesium and rubidium can form auride compounds)Gold is one of the noble metals. Noble metal is an alchemical term for metals that do not corrode under normal conditions.Gold is the seventh most dense metal.Metallic gold has no odor or taste.Gold has been used as jewelry since prehistoric times. Today, gold in jewelry is not pure gold. Jewelry gold is made of many different gold alloys . Gold is resistant to most acids. The acid aqua regia is used to dissolve gold.Elemental gold metal is considered non-toxic and occasionally used as a food additive.Transmuting lead into gold was one of the major gold of the alchemists. Modern nuclear chemists have found methods to accomplish this historic task.ââ¬â¹ Referencesà Los Alamos National Laboratory (2001), Crescent Chemical Company (2001), Langes Handbook of Chemistry (1952) International Atomic Energy Agency ENSDF database (Oct 2010)

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

Utilitarian Case Study Example | Topics and Well Written Essays - 250 words
Utilitarian - Case Study Example In utilitarianism, ethical behavior implies acting in the interests of the larger group, even if one must sacrifice oneââ¬â¢s own interests to do so, just as Posner did in the film. The welfare of the group matters not the individual. According to Mill, higher pleasures are logical or intellectual while lower pleasures are concerned with the physical needs. The role of pleasure is to provide happiness. Showing compassion for the society helps an individual care for the community in which he or she lives. Compassion is very significant to an individual in that it makes them realize the meaning and purpose of life, which is to be happy. This is because since every person wants to be happy, they will do anything to avoid misery and suffering. Virtues are important because they help human beings to derive pleasure in their actions, have uniformity in the way they act, and act promptly which in turn will result to peaceful co-existence, thus everybody will be happy about the life they live. Posner is following the principle of act utilitarianism in that he desires to die so that he does not cause financial constrain to his family. John Stuart Mill would support this principle because it aims to produce the greatest happiness for the greatest

Chronically Mentally III Population Essay Example for Free
Chronically Mentally III Population Essay The main focus of state and federal policies lies on the provision of support and long-term care services to the individuals with significant disabilities or those who are very old. These individuals, almost one and a half million, are taken care of in the nursing homes and Medicaid covers almost half of the total cost charged by nursing homes for their institutionalization (Tallon, 2007). While the total population of this special group of individuals only accounted for only 7 percent of the total population supported by Medicaid, it became expensive for Medicaid to support them as they accounted for almost half of the total expenditure of Medicaid. Policy makers therefore focus on changing the predominant service locus to community and home based from nursing homes (Diamond, 2009). Deinstitutionalization of individuals suffering from chronically mentally ill differs depending on the objectives and policies adopted from time to time. However, the interventions used to deinstitutionalize chronically mentally ill patients tend to share some lessons and parallels. History of chronically mentally ill population As state objectives and policies change over time, the history of the chronically mentally ill population in the United States has experienced significant transitions. Initial interventions, as from 1955 to 1980, policies and objectives were aimed at moving the chronically mentally ill individuals from the public mental hospitals owned by the state (Tallon, 2007). As a result of these efforts, the population of individuals residing in public mental health facilities reduced to 154,000 from 159,000 (Tallon, 2007). Later, there were approaches aimed at expanding and improving an array of services as well as supportive measures for chronically mentally ill in the community. There was massive closure of whole institutions which resulted to an increased emphasis on the rights which secured integration of the community. The rights that were emphasized included the right to have equitable access to housing (Bailey, 1999). States could fund small pilot programs since the community for those individuals who positively responded to antipsychotic agents which begun to be available. Thereafter, the national deinstitutionalization movement officially got launched through the programs for community mental health centers in 1965 (Tallon, 2009). Concerns over institutional conditions and the rights of citizens propelled further the need for the movement. The courts then limited the number of involuntary institutions and set minimum standards that were critical for institutional care (Diamond, 2009). The shift by states between sites of institutional care was fuelled by federal policy. The Commission on Mental Health Centers Construction (CMHC) program was intensively expanded in 1970s (Tallon, 2009). The coverage for Medicare and Medicaid was wide and it included mental healthcare services. Income support was mainly provided by the SSI (Supplement Security Income) program as well as the Social Security Disability Insurance (SSDI) (Tallon, 2009). The psychiatrist beds in community care increased in number after federal Medicaid provided sufficient funds as incentives. This saw the state moving individuals to the nursing home thus capturing the reimbursement from Medicaid which was not easy to find in mental hospitals of the states. In general, the overall progress of institutionalizing became immensely slow as the resources that were critical for community care. Until 1993, there were relatively fewer mental health dollars controlled by the state which served to assist in community care programs other than other state institution (Tallon, 2009). Although promising models of successful community care were provided and experimented, these models were rarely evaluated with rigor. They were also rarely integrated into the standard models (Tallon, 2009). The Nature of Chronically Mentally Ill Chronically mentally ill individuals suffer from bipolar disorder, schizophrenia, recurrent and sever depression as well as other several conditions which worsen their quality of living. A number of mental illnesses exist where some of them include schizophrenia, depression, dementia and bi-polar disorder (Szwabo, 2007). Individuals suffering from chronically mentally illnesses may present signs such as mental disturbances but these presentations vary depending on the type of disorder and age. Chronic mental illness produces major impairments in human functioning for a long period of time which normally covers the entire life span of an individual. For the chronically mentally ill individuals to get attention from the society, they require to negotiate with policy makers about a bureaucratic maze (Szwabo, 2007). A very ugly history about the chronically mentally ill patients exists where individuals used to be locked up and then forgotten. Today, there has been an emergence of state of the art hospitals, thanks to the historical forces (Bailey, 1999). The chronically mentally ill however, have been reported to face serious problems including incarcerations in the system of the criminal justice. This indicates how history is repeating itself and moving back to the pre-asylum ages when chronically mentally used to be locked in almshouses (Szwabo, 2007). However, the shift in the locus and pattern of mental healthcare that arise from the deinstitutionalization forces have all resulted in the missing link between the problem definition and modern efforts used to address the problem (Diamond, 2009). There also seems to be a lack of consensus on the clear mark lines which best define the chronically mentally ill individuals. There are no clear boundaries which can serve as a scientific guideline for national policy making process. Todayââ¬â¢s approaches of treatment of the chronically mentally ill have incorporated trans-institutionalization, increased support from the family and the shunting into the system of criminal system (Szwabo, 2007). It is apparent that this special population seriously requires socialization, in-patient care and shelter. Common Clinical Issues and Interventions in the management of chronically mentally ill individuals Care provision to the chronically mentally ill needs adequate planning, trained and committed healthcare providers from both clinical and social capacities and financing programming. There are many issues which need to be resolved in order to tackle challenges facing effective management of chronically mentally ill patients. Some of these issues are parity for mental healthcare services, availability of mental healthcare provider, care planning and broader case management coverage, education and training in mental health, and warehousing of the patients (Szwabo, 2007). Lack of parity continues to be an issue in the provision of healthcare among mental healthcare providers. This is due to the low amount of reimbursement made to social and nursing work. There is an intense lobby for social workers and advanced nurses to be reimbursed differently. There is also an inadequacy for the provision mental healthcare services. For instance, the reimbursement for the psychotropic which is an essential part of chronically medically ill is still inadequate (Szwabo, 2007). There is need to provide medical treatments apart from the psychiatric treatment interventions. However, major problems such as lack of adequate geriatrics to address the rising population of the aged have always been a weakness to the management of chronically mentally ill patients. It is also observed that attending to chronically mentally ill patients in nursing homes require access to suitable mental healthcare amenities. Unfortunately in many situations, access to living facilities, programs, trained staff and oversight becomes difficult to afford. Education and training for mental healthcare professions is inadequate as they lack facilities for long-term care (Bailey, 1999). It then appears that most managed care programs for chronically mentally ill patients are poorly managed, designed and therefore do not offer the required standards. The traditional mental healthcare systems only focus on reducing the costs of operation while failing to address the important element of patient care. In a capitated mental healthcare, the systems prompt physicians and other caregivers to limit medications to the least minimum in an effort to only manage overt symptoms. The practice literally condemns chronically mentally ill patient to medical starvation doses (Bailey, 1999). Summary and Future Considerations While the incidences of chronically mentally illnesses have increased and their prevalence well documented, there are still problems related to the use and access of general medical care. For effective management of chronically mentally illness in the future, there should be proper education for the healthcare providers about the condition. Service planning, outreach and assessment are also important elements in improving the way the condition is being managed. Mental healthcare providers should perform good service delivery monitoring and advocacy. In case of limitations of healthcare providers, psychiatric nurses can take the roles of consultation and supervision. The nurse can also execute roles as a nurse practitioner and deliver services in primary care. In the society, members of the family having an individual suffering from the condition should not neglect him or her. Instead, they should care for and encourage the patients.

How Radios Work :: radio
Radios are the most common wireless item in existence and are in most homes. We use them for entertainment, communication, as an information source, or even just back ground noise. For many of us radios are almost a necessity, but how much do we know about how they function? Antennas are one of the key pieces to a radio. Antennas come in a variety of shapes and sizes; they vary from large arrays to a small wire. Much of this variance is based on the broad use of radio waves and practicality; for instance you wouldn't use an antenna from a small radio to send a signal to a satellite. Antennas work by creating a resonating flow of charge along its element. The resonance is caused by a magnetic field fluctuating through an inductor that is fixed to a capacitor. As a magnetic field fluctuates across a conductor it causes charges to move. This motion causes an electro magnetic wave. The relations between the electricity and magnetism are explained by Maxwell's equations. Maxwell's equations are four equations that relate magnetic fields electric fields and charges and current. A radio wave is an electro magnetic wave. We modulate them using three different modulations, frequency modulation, amplitude modulation, and pulse modulation, to carry information. For frequency modulation slight variances are made in the frequency of the wave to represent different bits of information. This is widely used because it is less likely to have static. For amplitude modulation the height or amplitude of the wave is changed to contain information. Amplitude modulation is not only used by radio stations but it is also used to send the picture part of television. Pulse modulation is where there are breaks in the wave to indicate the desired information. This is usually used for morse code but can be used for a few other things as well. According to maxwell's equations radio waves travel at the speed of light. The magnitude of a wave will decrease at a rate of r^2. Where r is the distance from the origin. This is because the wave is propagates in all directions so the same amount of energy spreads out over a greater area. But how can we get signals from beyond the horizon? Today we could use satellites, but you can also bounce a radio wave off of parts of the upper atmosphere. This can be done because the sun ionizes levels of upper atmosphere.
