Biometrics and Wireless Technology - Essay Example This technology is now the more favoured method of identification over traditional methods like password and PIN identifications. High numbers of passwords and PINs are generated on a daily basis as more and more people are settling in with the pace of technology. These PINs and passwords are saved electronically on database servers, which at some point may run out of space. In this scenario, the better choice for a person is to be her or his own password. In today's market many types of biometrical identification tools are available such as fingerprinting, face recognition, finger and hand geometry, iris recognition, voice and signature recognition (von Graevenitz 2003). Biometric data collected using sensors are converted to digital formats for storage into computer databases. Fingerprinting biometrics has been long in use by the crime solving agencies and immigration authorities. However, technologies to use iris, face, and voice for recognition are still in their infancy. According to the founder and chairperson of CardTech/SecurTech, Ben Miller, biometric technologies have been in use since 1968. The University of Georgia was a pioneer in the use of biometric technology when in 1973 the university set up a hand-scanning system that helped restrict entry into its all-you-can-eat dining halls. Fingerprinting, iris recognition, retina recognition, face recognition, and hand recognition have been successfully imple... Fingerprints are then stored in image formats or encoded character strings. This technology is cost effective and very accurate (Biometrics 101). Irises are also a unique characteristic that can be scanned saved in a digital format. Since irises remain unchanged after surgery or with the use of glasses or contact lenses, this technology is fast gaining popularity (Biometrics 101). Retina recognition systems are used in some high-risk facilities such as military installation systems. This technique is considered the most accurate among all available biometrics technologies. However, the installation cost for this technology is high (Biometrics 101). Face recognition systems analyse the facial geometry of a person and can verify a person's identity within a very short time and from a distance of 2 feet (Biometrics 101). As the internet age has progressed and matured, it has seen the advent of wireless technologies, which have brought flexibility of communication, as wireless systems do not need any physical connections. Transmission of data in wireless systems takes place through radio frequency. The popularity of wireless devices such as mobile phones, PDAs, smart phones, and other handheld devices is at its height at this time. Karygiannis and Owens (2002) recognised that wireless networks are at the same risk as wired networks but they are also vulnerable to a few new security threats due to the limitation of wireless protocols. For security implementation, in wireless systems biometric technology is getting a lot of attention as it provides an extra level of security. It can be used as a stand-alone security device or along with another protection system. Agencies that need higher levels of

Leadership Styles Essay Example | Topics and Well Written Essays - 1250 words

Leadership Styles - Essay Example The case study related to Lake Community Hospital provides a classical example on how the leadership style implemented impacts on performance. Introduction The leadership style adopted by managers of various organizations impacts on the staff either positively or negatively. The relationship that exists between leaders and group members is one that requires a reciprocal interaction. This provides better understanding within the organization and allows a harmonized delivery of services (Raup, 2007). Efficient leadership style that takes into consideration the input of workers is crucial in terms of motivating the staff. Further, an efficient leader needs to relate positively with the staff. This allows the leader to develop a clear perception related to worker’s needs. In the case of Jamie’s unit, her staff is not happy about the move to another unit under different leadership. This is due to the uncertainty of the treatment they might receive under new leadership. The c hange means Jamie’s unit has to adapt to a new leadership style (Raup, 2007). While considering Jamie’s case and his staff, this paper explores different leadership styles used by administrators or managers. ... This is evident from the high turnover rate among nurses working in the unit and the disillusion among nurses from Jamie’s unit. In this regard, the leadership theories that the nurse manager at the telemetry unit may adapt include: Contingency Theory This theory is essential in situations where there is need to consider different variables. This assists in determining the type of leadership style to implement (Leon, 2007). In relation to this theory, there is no one leadership method that work for all situations, hence, need to adapt to the prevailing situation. There is a dilemma in regard to the transition at Lake Area Community Hospital. This involves how best to integrate nurses from Jamie’s unit into the telemetry unit. In such a case, there is need to allow for a smooth transition (Jogulu, 2010). This would involve incorporating Jamie in the management of telemetry ward in terms of assisting the managing nurse to improve relations with the new staff from Jamieâ⠂¬â„¢s unit. Since, Jamie would not have any position after the transition is complete, Jamie’s services is important in terms of improving working relationship between the new manager and his former nursing staff at the 12 bed unit. Situational Theory This theory presents a framework whereby, a leader is expected to select the best alternative leadership style that considers the situational variables (Lorita, 2005). The Hospital is in the process of shifting into a plan that would improve the management of staff and patients. As a result, the decision to down size is meant to improve service delivery. The nurse manager at the 39 bed unit has a larger responsibility in terms of managing a bigger unit, compared to Jamie’s former unit. Further, the nurse manager has to adapt to the needs of

Nuclear Energy disasters and the effects on the Environment Research Paper

Nuclear Energy disasters and the effects on the Environment - Research Paper Example This notion continued until 1803 when an English chemist John Dalton revitalized the old notion and used it to explain various problems, which chemists at that time were struggling with. Rather than any of the experiments resulting to the idea, it surfaced from analysis of several experiments involving chemical reactions and properties of gases. Daltons theory became popularized and established experimentally in the course of early 19th century (Rogers, 2013). Most of the points mentioned above are still recognized by most current scientists, except for some few points. First, the radioactivity and nuclear fusion/fission discovery resulted to revision of point (b). Isotopes confirm that atoms of a similar element can in reality exhibit small disparities because of a diverse number of neutrons (Mara, 2011). In addition, the ions’ existence with unreliable electrons’ numbers also contradicts this point. Point (e) has also been nullified by nuclear physics, because atoms can certainly be destroyed in the nuclear chain reactions. Moreover, point (d)’s second item, is somewhat incorrect, as, for example, water is H2O, but not HO (Mara, 2011). Dalton’s assertion that atoms merge in equivalent amounts to create compounds delayed acceptance of the theory for a long time. In spite of today’s perspective, Dalton remarkably contributed for his time and since then his name continues to receive honor from its association with the theory. In nuclear power, nuclear accident means events, which emit certain amount of radiation that are likely to be of harm to the health of the public and also to the environment (Bortz, 2012). Normally, the nuclear accidents are categorized as nuclear incidents and accidents by severity. In addition, while the radioactive accidents and nuclear accidents are included for perfect understanding, nuclear accident can result from the failure of a reactor of a nuclear power plant radiation. Regardless of the fact that some

How do the governments of the Communist East and the Capitalist West Essay

How do the governments of the Communist East and the Capitalist West perpetuate the Cold War - Essay Example Yet this perpetuation of the Cold War corresponds to the anticipation and autonomy to those subjugated in the East Germany and, on the other hand, the cruel existence of Communism to the Capitalist West. This particular transitional zone situates Alec Leamas, a spy of Britain coming up for the defection of one of his secret agents. The subjected man emerges over the border and seems to be set to make his 'run away' when, all of a sudden, he is chopped down in a bombardment of gunfires. Leamas is called again to London by his supervisor, Control (Cyril Cusack), anticipating him to be fired from his job. And then Control changes his mind to keep more Leamas in a Cold War. Though, Leamas is immediately started searching for a job and finally he got a tedious librarian job. With his only companion, whisky, for company, Leamas simmers in his own beliefs, buttressing the detestation not in favor of the British Secret Service. Nobody seems able to make a way into his shell (developed over the time when he was a secret agent) even though his associate librarian, Nan Perry, takes a predilection to him. Regrettably, Leamas beats up a storekeeper and finishes up in a lockup. Nan should like him nonetheless, and also the Leamas in return, since she congregates him on his liberation from jail. The interesting thing that took place is that, there is one more there to see his come back and he comes up to him in the park. Claiming to be from an aid organization which facilitates ex-convicts, Carlton (Robert Hardy) takes Leamas to a pricey lunch. This is completely gibberish for sure -- as a matter of fact it's an approach from the foe, inspecting a peeved previous secret agent and detecting if he'll defect. Leamas appears to undergo that he doesn't owe Britain anything and, rather grumpily, looks to believe (of course, by means of having the only purpose of wealth). After that Leamas circuitously moves towards Smiley's residence, for a get-together with Control. Everything turns out to be obvious Control sketches the plan, a deceitful and wicked endeavor to harm the reputation of the apex East German secret agent, Hans-Dieter Mundt. With eagerness, Leamas is rushed towards Holland for de-briefing by Fiedler, the second in power to Mundt. The bottom line of the arrangement is that Fiedler loathes Mundt and would wipe out him at all cost. By plummeting slight clues in his discussion with Fiedler, Leamas lets the spy to pencil in his own thoughts without so much delay - the unbelievable ability that Leamas has for spying and espionage, and his great understanding skills, embraces him in good stead as he intertwines a compelling story for Fiedler. Realizing the "certainty", Fiedler sent Leamas back to East Germany, where he looks forward to to overthrow Mundt in a closed trial and assessment. Leamas is an additional snag though since his persistence that Mundt couldn't have been a spy or espionage (he was leader of East German maneuvers and probably would have acknowledged). Fiedler still controls to induce an assessment however, completely influenced that Mundt is being disloyal to his State, and then the closed session starts on. It appears as though the court will rule alongside Mundt, ensuing in his carrying out, in anticipation of his defense representative presents an unforeseen and unanticipated

Improving Organisational Performance Assignment - 2

Improving Organisational Performance - Assignment Example Management requires higher attention towards proper understanding of individual differences, needs and behaviors, and any technicalities to facilitate their understanding and management of the organizational complexities. Even though organizational performance is an idea that is perceived through the accurate measures of efficiency, effectiveness and adaptability, its enhancement begins at the bottom most level of elements composed of these measures. A manager has therefore to analyze individual performance measures in order to initiate the process of performance improvement. The main issues to be addressed in the performance improvement process include keeping focus on the measurable results, success driven by employee empowerment, measurement of results to be delivered immediately, and building on the present success for the projection of future success (Armstrong, 1994). Requirements set by the performance improvement process do present some complexities and therefore requires sol utions by an appropriate methodological approach, capable of leading the entire process form the general perspective to a detailed insight and as well from an abstract insight to more practical solutions as can be used within an organization (Alasdair A. K., 1995). In addition, the modeled approach should be pragmatic enough to be applied to an existing setback, which thereafter leads to the requirement of designing processes involving a number of stages of the organizational performance improvement process. Elements of project organization structure The organizational structure of a project is made up of five key elements which include: i. Program Committee This is a temporary body set up to organize and coordinate the workflow of the entire performance improvement program, and also give directives in the program implementation strategies. A program committee consists of a chairperson of the board, top management members, and the program manager; and is headed by the CEO of the cor poration. ii. Program Manager A program manager is an expert and a technocrat who is responsible for the program implementation, appointed by the program committee. He/she is charged with the duties of coordinating of individual project teams, sensitizing the program committee of the status of the ongoing activities, cooperative planning of project activities with the project managers, cooperative design of the project network charts with project managers, and controlling of the implementation of solutions reached within the project. iii. Project committee This is a group of experts, who organize and coordinate the workflow of any individual project and directing its implementation in accordance to the common program plan. A project committee is a collection of both the experts delegated by organization owners and the staff experts to ensure full implementation of the program. The project manager is also a member of the project committee to ensure effective communication between the project committee and the project teams. iv. Project team This consists of experts who are actively involved in the implementation of the project’s activities. Its membership is based on full-time basis. Positions on the project team include the project manager and the project team members. Within the project team is the project manager who is an expert mandated to directly manage the implementation of project activities. A project manager is appointed by the project commi

COMPARE THE RIGHTS AND RESPONSIBILITIES OF A UK ADULT CITIZEN AND A Essay

COMPARE THE RIGHTS AND RESPONSIBILITIES OF A UK ADULT CITIZEN AND A REFUGEE OR ASYLUM SEEKER BOTH LIVING IN THE UNITED KINGDOM IN TERMS OF HEALTH AND SOCIAL SECURITY - Essay Example This essay compares the rights and responsibilities of Asylum seekers and adult U.K citizens in terms of health and social security. The United Kingdom adult citizens exercise their rights and responsibility of contributing to the issues of health and social securities by voting and raising public opinions to the government. In contrast, the contribution of asylum seekers in these issues is minimal due to language barriers. The government tries to involve them by providing them with channels to communicate and give their decisions regarding the issues affecting them (NRIF, 2006: CRC, 2004). For instance, the ‘English for Speaker of other Languages’ program aimed at teaching English to this group of people (ISE, 2005: Ragu, 2008). This effort aims at improving their communication abilities so that they can be able to take up their rights and responsibilities. All adult citizens of U.K. have an absolute right to the National Hospital Services (NHS), which includes free medical treatment and care. On the other hand, not all Refugees and Asylum seekers receive this facility (Aspinall & Watters, 2010, p.23). Those asylum seekers who have not received permanent residence confirmation from the government cannot access this facility. They have access to the medical services but at their own cost (Palmer & Ward, 2007). Those who have received confirmation enjoy national health services (NHS) without any payment (Crawley & Crimes, 2009). All adult citizens in U.K. have the right to register with a general practitioner of their choice free of charge. If a general practitioner cannot register them, he or she should give a substantial reason in writing to explain the cause (CIC, 2007). Contrary, refugees and asylum seekers may apply with general practitioners (Lee, 2006: Refugee Council, 2005). However, the general practitioners have the right to consider such applications and decide whether to accept them or

Deregulation of Aviation in the Commercial Airline Industry Research Paper

Deregulation of Aviation in the Commercial Airline Industry - Research Paper Example Later, airline safety regulation was passed together with 1958 Federal Aviation Act that bore Federal Aviation Administration. By 1938, US government was regulating much commercial aviation in terms of routes, schedules and fare. The three main functions of CAB are regulating airline route, limiting new market entrances by air carriers, and regulation of passenger carriers. CAB report shows typical regulatory thinking. Without certain circumstances that give sound reasons for new carriers, inherent desirability to increase the airline industry was not valid. The 1978 Airline Deregulation Act deregulated many of these controls and completely changed the civil aviation face in the United States. In order to serve any given route, an airline was required to seek permission which led to many barriers in the permission granting. Consequently, the system was removed by airline deregulation including the dismantling of the flag carrier notion. However, this caused a new problem because many civil suits were filed in state or federal court against an airline. While the court handled breaches of contract and personal injury claims the transportation department had neither the facilities nor authority to mediate or try many disputes between airline and consumers (Johnson, 2008). Therefore, many consumers have been left to search for themselves legal justice with their claims. This is enhanced by the Open Skies Agreements between United States and other nations which have opened the aviation market to foreigners and removed competition barriers. This allows airlines to operate their air services to any point of other countries from any point in United States. These agreements have successfully removed competition barriers as well as allowing... The researcher states that in 1978, the United States signed an airline deregulation Act, and later developed a new regulation form, to deal with allocation of scarce availability of slot numbers in the airports and other problems that may be as a result of this scarcity. With cost and price competition views, various solutions were proposed, in order to control the routes served and the prices charged by major airlines. Airline deregulation has yielded and continues to yield uncountable benefits to travelers who fall in the average category. The positive deregulation consequences were significant drop in fare prices, improvement of security, service and programs, among others. Reduction of fare helped passengers to increase their savings, where it is estimated that they saved up to $ 100 billions. It also allowed smaller airlines to proliferate into the big carriers market. Generally, the larger airlines suffered negative consequences of airlines deregulation like bankruptcy, collap se high operating losses more than the smaller airlines. However, millions of flying passengers and smaller airlines gained the better benefits of airlines deregulation. Though smaller markets were not affected by service erosion as predicted by deregulation opponents, larger airlines had nothing to small to smile at, as competition exposure made them suffer heavy losses through labor union’s conflicts. As a result, many of them were liquidated, especially those that were founded in the after deregulation.
