How do terrorists justify their actions Essay Example | Topics and Well Written Essays - 500 words

How do terrorists justify their actions - Essay Example It can be understood that a terrorist might not be a born as terrorist. Some factors then in his life could be responsible for his becoming a terrorist and not being any other professional. The activities of the terrorists might not be justified from the point of view of the common people who are killed. However, the actions of terrorists might have their own justifications. A challenge encountering the norms of International Humanitarian Law provides one justification for the acts of terrorists. According to this view, all of the individuals who are considered as non-combatant might not be innocent. These people become targets of such violent measures. Many times the effect of family might be a cause. For example, a child whose father had been a terrorist might in a natural process become a terrorist as well. Many terrorists groups are performing such acts on the name of the All-Mighty. A second justification might arise from the issues of humanity reflecting the terrorist actions to be their fights for humanity. It might also be that the individuals involved in terrorism might possess mental disorders or they are psychologically weak and suffer from lack of power (Saul, 2006). There might be personal factors or at times different situations might be responsible in compelling the individuals to perform such heinous acts. Violent acts can be closely associated with psychological difficulties within an individual (Borum, 2004, p.10). Thus psychological factors may be considered as one serious reason for justifying the acts of terrorists. The group reinforcement is another factor of concern. Many times, the probability or the rate of such performing such acts may increase as an effect of group reinforcement where the terrorist groups may be responsible in compelling an individual to take such measure (Fatout, 1992, p.63). Thus, the group of terrorists in which an individual has become part of might influence the individual to

Technological and community Essay Example | Topics and Well Written Essays - 4000 words

Technological and community - Essay Example â€Å"We are now living in a globalised world† seems to be a favorite catchphrase among authors and writers, and applicable to businesses and organisations because transactions can be conducted at an instance, and people can communicate from one side of the globe to the other end with just a personal computer and an internet connection. Moreover, because of globalisation national borders are not very important now, and there is the interconnectedness of organisations and businesses, while countries focus more on deregulation, privatisation and liberalisation of industries, and the importance of world markets. Global firms use many different structural forms in dealing with globalisation. They can use the horizontal structure because this is made easier with the availability of the internet and Information Technology. Globalisation affects very much the ordinary community. Significant social changes can take place both before and after the phases of the most intense physical activities, for example, construction, production, and expansion; pathways of influence can be social as well as physical. Nevertheless, the technological changes have brought about inequalities because of the digital divide in the community setting where there is lack of technological attention from the government and the business or private sector on the part of these communities which are seen to not being able to contribute to progress and development. No human enterprise can surpass technology’s success in improving the material conditions, enhancing the cognitive attributes, and attenuating the physical limitations of humans. While some celebrate the coming of unprecedented wealth and prosperity brought on by the recent advances in genetic engineering, nanotechnology, computer-communication systems, and so on, others bemoan the possible demise of humans as autonomous social beings because of the coming of the so-called cyborgs, transgenic organisms, and clones.

Hulu Research Paper Example | Topics and Well Written Essays - 750 words - 1

Hulu - Research Paper Example This paper will discuss the history of Hulu, as from 2007 to 2012. The name or phrase Hulu came from two Mandrin Chinese words, hu and lu meaning interactive recording (Hulu 1). The Hulu venture was made public in March 2007. Its main partners were MSN, AOL, Facebook, MySpace, Comcast and Yahoo. The company’s CEO was and still is Jason. He was made CEO in June 2007 (Barnett 1). The phrase Hulu was selected in August 2007, when the website was made official and started to stream. Hulu first invited its users to give them their email addresses for an upcoming beta test. Hulu began, in October 2007, the private beta testing through invitations (Barnett 1). After that, the network allowed its users also to invite their friends to the website. However, Hulu first launched for public access on 12th March, 2008, in the United States (Hulu 1). The first product to launch was HULU Syndication network. The network was developed and designed by the NBCUniversal team from New York. Hulu.com destinations site was the second product to be launch by Hulu ( Barnett 1). The network started an advertising campaign in NBC’s show of Super Bowl XLIII, with an ad featuring Alec Baldwin. The advertisement was titled Alec in Huluwood. The advertisement, aimed at humorously portraying the shocking secrets behind Hulu, made the site to look like an evil plot planning to destroy the globe. The ad suggested that Baldwin was, in fact, an alien in disguise (Barnett 1). However, advertisements kept on flowing throughout the media with media personalities such as Seth MacFarlane, Will Arnett, Eliza Dushku and Denis Leary. Disney made public, on 30th April, 2009, that it would be joining the venture and purchased a 27% share of Hulu (Hulu 1). During an industry conference, on 21st October, 2009, Deputy Chairman of News Corporation, Chase Carey argued that Hulu needed to advance in order to have a significant subscription

Literature Review of Risks Prevention of Pressure Sores

Literature Review of Risks Prevention of Pressure Sores A review of literature provides the concept to continue for the contemplated research, an understanding of the status of the research in the problem area includes research approach, method, instrumentation, and analysis. The literature review is organized under the following headings: Review related to the prevalence of pressure sore Review related to the etiology and risk factors of pressure sore Review related to the prevention of pressure sore Review related to the caregivers of pressure sore Review Related to prevalence of pressure sore Hendrichova.I et.al (2010) have done Retrospective analysis of 1414 clinical records of patients admitted over 6 months and found prevalence of pressure ulcers of 22.9 % and incidence of 6.7 % Forni C et. al (2009), conducted study regarding cohort study of the incidence of heel pressure sores in patients with leg casts at the Rizzoli orthopedic hospital and also the associated risk factors at Italy. He found that out of 216 patients 17.6% (38) developed a pressure sore: 16/124 in orthopedic wards; and 22/92 in cancer care units. The related risk factors of pressure sore were noted are administration of anti neoplastic drugs (p = 0.033) OR = 2.61; skin redness before cast application (p = 0.001; OR = 4.44), reported symptoms after the application (p = 0.000; OR = 7.86). Most of the pressure sores were mainly in the stage 1 and stage II was 6/216 (2.4%). Voweden KR and Vowden.P (2009) conducted study regarding the prevalence of pressure ulcer, management, equipment provision and outcome for patients with pressure ulceration and identified in a wound care survey within one English health care district on 1000 population in the tertiary referrals and prevalence of 53.7 % were classed as grade 2 pressure ulcers, 48 % were grade I and only 35 % of grade 4. Pressure ulcers were identified through the critical incident form are only about 11 % of pressure ulcers at hospital setup and gives the current Epidemiology of pressure ulcers. Harrow J.J et.al (2008) conducted study regarding pressure ulcers and occipital alopecia in operation Iraqi Freedom poly trauma casualties: retrospective review from 2004- 2006 to detect the prevalence and severity of pressure-related injuries and stated that 38% of admissions to this hospital had pressure-related injuries on the day of admission. In which Casualties from Iraq had a higher rate of pressure ulcers (53%) than other area (22%). Occipital lesions accounts 50% of non-stage I pressure ulcers and more severe than of the sacrum or in the extremities. Review related to risk factors associated with the pressure ulcer: Lahmann N.A.et. al (2010) done, study regarding impact of prevention structures and processes on pressure ulcer prevalence in nursing homes and acute care hospitals, by the method of prevalence survey among 7377 residents in 60 nursing homes and also 28,102 clients with 82 acute-care hospitals at Germany by annual point prevalence surveys. Results noted are nosocomial prevalence rates in hospitals decreased from 26.3% during the first year to 11.3% in the last year (mainly in nursing homes from 13.7% to 6.4%). The usage of pressure ulcer-related structures conspicuous more during each repetition to more than 90%. Fisher A.R et. al (2004) conducted cross sectional prevalence studies among 535 patients regarding f pressure ulcers in adults in acute care settings at university teaching hospital, Canada and found the prevalence of pressure ulcers was 27% (at 95% confidence interval, 23-31%). Total Braden score below 17 and increasing age were significantly associated with the presence of pressure ulcers and also found majority of the risk factors are increasing age, less activity level, friction and shear while seated or lying down were associated with hospital-acquired pressure ulcers, only increasing age, friction and shear were associated with the presence of pressure ulcers in the whole sample. Silva M.S et.al (1998) conducted exploratory- descriptive study to identify, in the specialized literature, which predisposing conditions and risks factors would be related to the development of pressure ulcer, and to verify how often these predisposing conditions and risk factors would be present in bedridden patients, hospitalized in an institution and concluded that there is the need to construct an instrument to measure this risk must suit our reality and that incorporates risk factors identified with a significant frequency in this study and are not contemplated in most of the available scales in the literature. Review related to the prevention of pressure sore Baldi et .al (2010) conducted study regarding Studying factors related to pressure ulcers prevention: a marginal scale model for modelling heterogeneity among hospitals. in patients referred to several Italian hospitals, with the method of prevalence survey co ordinate through the European Pressure Ulcer Advisory Panel among 12 000 hospitalized patients in Italy, and results shows that the prevention of pressure sore includes usage of Braden Scale, age and assistance- connected aspects, and usage of preventive equipment combined with a repositioning techniques. Wann-Hansson C et .al (2008) conducted study in sweedish University regarding Risk factors and prevention among clients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present during admission with 535 clients and notified the prevalence rate of pressure ulcers were 27% (95% confidence interval, 23-31%). Shahin E.S (2008) conducted study regarding prevalence of pressure ulcer among intensive care cltients: a cross sectional study at German with the sample of 1760 clients in order to assess the pressure ulcer prevalence among intensive care clients, and also found clients characteristics and preventive measures related to prevalence of pressure ulcer clients and to assess the most common sites of pressure ulcers. A result shows a mean prevalence rate was +/-30% from 2002 to 2005. The pressure sore prevalence was decreased to 16.2% in 2006 and half of the pressure ulcers were in grade 1. He has stated the significant association between the age and pressure ulcer (P

Criminal Justice Organizational Trends Paper Essay

The advancement of technology is affecting everyone in their everyday lives whether we want to accept it or not. The criminal justice system is no stranger to this; it has created more work for them and in order for them to keep pace with criminals they have to continue to evolve and stay current with the progress of technology. Technology changes from one day to the next and in order to fight and prevent crime the criminal justice system must stay current with the many changes of technology. Their success in the fight against crime depends on how well they are able to adapt to the changes. The writer will talk about the use of privatization and militarization of the criminal justice organizations as well as different behavior theories and the effect of societal and organizational diversity and the use of the criminal justice motivational theories matrix in this paper. â€Å"Privatization† can be accomplished in a host of ways; in its most basic form, it is the adoption of public functions by private entities or  individuals (Finegan). Privatization has had a heavy effect on the criminal justice system and punishment systems. This is definitely not a new idea; it is in some ways a return to what was done years ago. Before the nineteenth century private groups and individuals handled the majority of criminal justice functions. The privatization of law enforcement services are on the rise, and as a result law enforcement agencies will be in competition with private organizations for law enforcement services (Harvey). It’s time for American police to remember that they are supposed to protect and serve our communities, not wage war on the people who live in them (n.d.). Law enforcement agencies everywhere are spending billions of dollars on military type equipment to use in their everyday policing, acting as if the neighborhoods they serve are warzones. As Ryan Grim said in the Huffington Post in reference to the situation in Ferguson, Missouri, â€Å"Police militarization has been among the most consequential and an unnoticed development of our time and it is now beginning to affect press freedom† (Timm). Radly Balko of the libertarian Cato Institute is highly critical of the way police tactics and swat teams have grown in this country. He believes that swat teams have a place in larger jurisdictions but not so sure about the smaller jurisdictions. Balko is especially critical of the way swat teams are used in an unsuitable fashion when conducting routine police work and where an individual’s civil liberties are often violated and where the swat team mistakenly uses force against innocent people. Diversity within the criminal justice system has both positive and negative effects throughout our communities. There have instances where unethical practices of discrimination, bias, and prejudice have been committed against minorities in our communities. These practices have been performed by prosecutors, law enforcement officers and judges who have been designated with the power by our state and federal governments. United States in the twenty first century is facing multicultural societies; individuals working in the system are characterized with defendants,  society, inmates, victims, political leaders and professionals all originating from diverse cultural orientations (Barlow, 2000). The government believes that cultural diversity in the United States contributes to creative thinking, policy changes, new ideas and looks at laws, procedures, and policies that contribute to inequality and equality. There are some people that support the notion that laws protecting minority group are a direct result of cultural diversity, and these people are inclined to be against such laws. While the advancement in technology might decrease the need for additional police officers, there are other factors that just might cause a different effect. The first change is our overall demographic change, a rise in people of color. This increase unfortunately has also caused the crime rate to increase. Therefore the changes may just cancel one another out and in order to provide adequate service and protection to our communities, the law enforcement agencies will probably need to maintain their current staff levels moving forward. While law enforcement agencies will be held accountable like never before, both for their actions and what happens in their jurisdictions, they need to do more in preparation for the future. They can select, place and train their employees to assure their success through the appropriate jobs, good organizational structure, and an emphasis on strong ethical values. References Barlow, H.

Benefits and cost

Costs would be Just the opposite of several of these, but would also include lack of a good warranty, or not being able to find a place that can service the time-piece.

The Lead Up to Gulf War II essays

The Lead Up to Gulf War II essays The United States wants to launch a pre-emptive attack on Iraq. The US alleges that Iraq possesses weapons of mass destruction with intentions to use them against the US and its allies. There is growing skepticism about Americas claims and worldwide as anti-war demonstrations against any kind of military force against Iraq have come about. The weapons inspectors from the UN are trying to find these weapons in Iraq despite the Iraqi governments claims that they dont have anything they arent supposed to have. The US has presented mostly circumstantial evidence, such as intercepted conversations between military leaders in Iraq, and satellite photos. In those intercepted conversations, the people were talking about evacuating ammunition. The people werent talking about destroying it of giving it up for inspection. The US believes that Iraq never abandoned its weapons program. Many missiles that were left over from the Gulf war were unaccounted for wen Iraq released details of all the weapons the country has. In early September, a report from the International Institute for Strategic Studies (IISS) supported the American argument that Saddam Hussein has never given up his quest for a nuclear bomb. The IISS report suggests that Iraq could put together a nuke within months if it could get enough plutonium of uranium. It also says that Iraq has been able to keep together its scientists. Although the technology has been destroyed by the Gulf War, the knowledge still exists. However, quite a few obstacles are in Iraqs way if it wants to possess nuclear weapons. Before the Gulf War, Iraq could have been close to producing enough uranium its weapons, but the war stopped the work on it. Sanctions from the United Nations means that Iraq no longer has the facilities needed to make a nuclear bomb. In addition, Iraq would have to import resources to make the bomb without the world noticing. In order to build...

Teaching Project Assignment Example | Topics and Well Written Essays - 1000 words

Teaching Project - Assignment Example In terms of the appropriate level since the objective of in teaching endotracheal tube nursing care is for the students to provide safe patient care in using endotracheal tubes, it would seem more appropriate that teaching would not only focus on theories but also on hands-on learning. Since the group is composed of students who will experience this material for the first time, a concise and practical way of presenting the material would prove to be easier to absorb. Practical in the sense that the material would be presented in terms of its importance in real-life practice of the nursing profession as far as this area of patient care is concerned. After having learned the theories relating to endotracheal tube nursing care, students should apply the information they have learned in class through situational exercises in the classroom, which would somehow assess how much they've learned and their ability to demonstrate this knowledge in real life situations. Based on the stated objective which is "Students will be able to perform endotracheal tube nursing care," such an objective if assessed using Bloom's taxonomy, the level of objectives that was set for teaching the students is more on performance. Although the content of the teaching plan includes "knowing" the purpose of the procedure, equipments needed, preparation, post procedure, outcome, and documentation, the bottom line is on whether or not the student would be able to perform the said procedure after all this intellectual input. Therefore, the objectives are in the level of psychomotor, as students would be evaluated if whether or not they would be able to perform endotracheal tube nursing care and consequently provide safe patient care. Teaching Method The teaching method that would best meet the group's need would be through equipment demonstration, lecture and the use of relevant CD-ROMS. These methods are seen to be essential in learning and understanding as well as applying knowledge into real life practice. Demonstrating the equipment used will not only give the students of what kind of equipments are involved, but they will also know what it is called, its function and how they would use it. The lecture provides theories and other important information on the matter as well as an opportunity for the students to equip themselves with the knowledge needed to be able to perform a particular task. The use of CD-ROMS would also help in reinforcing the information given during the lecture. It can also serve as a window of opportunity to illustrate and show students the picture behind the words they heard during the lecture. The method of teaching used can be categorized as direct teaching, because it is the teacher who mostly does all the work as will be manifested in equipment demonstration, lecture and CD-ROM. As such, direct teaching needs to be prepared and organized in advance and this includes teacher's having information about their students' prerequisites for the lesson. The advantages of this method of teaching are: there is a specific target for learning, students are given reasons on why the content is important and thus helps to clarify the lesson's objectives. It makes measuring of student's input relatively easy, it is a widely accepted and used

What should 21st Century Environmentalism look like Essay - 1

What should 21st Century Environmentalism look like - Essay Example Globalization and World’s processes like cyclones are environmental problems that affect almost all human beings. The 21st environmentalism has formidable challenges and dangers safety concerns. Increased cases of storms, cyclones, droughts, floods are of global concern. Extinction of species, meltdown of glaciers and low food production are the resultant features of global warming. Several nations across the globe are worried on the ozone layer, change of climate and wildlife threats. These challenges have put a worrying picture on how the environment will look like at the course of 21st century. The main environmental issues like, pollution, deletion of the ozone layer and Global warming leaves us with the question; what should 21st century environmentalism look like? Each of the above problems and others not mentioned, have the cause, environmental impact and a possible solution. Both solutions and measures for environmental problems are in the same path. A huge chunk of these problems originates from developed societies with many industries. They affect the environment in the amount of resources they consume and pollutants they produce. Both the developed and developing countries contribute to environmental degradation, for instance the oil rich gulf-region experience depletion of environment during oil extraction. Developing and developed countries use the same oil in industries production and motor vehicles, causing air pollution and thus depleting ozone layer. The 21st century environment has serious threats caused by humans; the earth’s natural resources are in extinct. The use of land is a concern in 21st century; man encroaching in the habitat of wildlife destroys its ecosystem, destroys the underground water and desertification. Industries emit toxic chemicals, which interfere with aquatic animals, and soil erosion. Environmental challenges causes water crisis, water pollution and global warming interfere with the
