Criminal Justice - Homicide Studies Research Paper

Criminal Justice - Homicide Studies - Research Paper Example Report on the Ethics Committee, 2010 The Ethics Committee reports regularly to the American Psychological Association. In its report of 2010 the committee has address the topics pertaining to the ethical issues such as psychologist consulting to reality TV programs, psychotherapy, issues related to psychologist, giving psychological treatment over the internet, etc. In 2010 the Ethics Committee responded to majority of the requests received by the office and attended 46 workshops and discussions on national and international level throughout the year. The responsibilities of Ethics Committee includes to consider the individual cases, cases of the state licensing board or court and finally those which result from committee’s own initiative after getting information from the public. The Ethics Committee starts its working when it receives an inquiry letter from an individual. The show case process starts with a notice from the state licensure board. Then the preliminary investig ations are made to decide whether the case should be closed or it should proceed to the level of formal case. These investigations provide detail information about complain. Formal cases are opened if the responded proved to be charged for ethical violation. The cases pertaining to ethics which meet the threshold criteria are then referred for resolution. The sanctions described in Rules and Procedures (APA, Ethics Committee, 2002) includes that the individuals should be terminated from the APA membership or they should be reprimanded or censured. In the cases reviewed by the committee in 2010 no reprimands were made, there were two cases of censure and five cases of loss of membership. Crime and Delinquency The American population is exposed to pictures of crime and delinquency through all the digital devices and social media which results in fear and affect the attitude of the people and their voting habits. Politicians are using crime and delinquency in their policy agendas to at tract people to vote for them. The relationship between crime, delinquency and political science is determined by deterrence theory, conflict theory, labeling theory and radical theory. All of these are related to the main topic because they are considered important by the political science, crime and delinquency scholars and the theories include the analysis of government and political institutions. The theories are useful in explaining the government and political processes about the criminal acts. After selecting the theories further research articles were obtained from J-store sociological database on the basis of contemporary theoretical trends and past development of the tactic. The results showed that the societal fears gives rise to criminal acts and ultimately ends on criminal punishment. Deterrence theory suggests that the criminals should be punished publically so that it discourages the public to involve in such activities. Conflict theory suggests that criminal acts hav e their roots in the instability between political and social groups. According to the labeling theorist the criminals should be labeled negatively but this negative label can encourage the criminals to act in the same way in future as well. Historical records have shown that the labeling

Blood Donation Marketing analysis Research Paper

Blood Donation Marketing analysis - Research Paper Example The collected blood will be supplied to the military camps, churches, community organizations etc for emergency purposes ( American Red Cross, 2010).The guidelines, benefits of the blood donation camp are available for free through social media networks like Facebook, YouTube and Twitter (Donate Blood, 2013d). Weakness Recruitment of first time blood donors require extensive identification, education and motivation. Training, educating and motivation these first time blood donors consumes a lot of time (Red Cross, 2010). The trainers have to maintain a record of the first time blood donors since the repeat donors are already provided with an identity card by the blood organizer camp. Apart from time consumption, the blood organizers have to deal with the pre donation anxiety and nervousness of the first time blood donors. Opportunity The benefits about blood donation are being taught to the college children, this has eased the task of the blood donation camps to communicate the benefits of blood donation. Technological development has made it easier for the blood donors to schedule their appointments online (Donate Blood, 2013e).... †¢To develop an integrated marketing communication strategy which motivates current, non and lapsed donors in the target market to increase their blood donations in 2013-14. †¢To improve and increase blood donation accessibility for the 18-24 year-old age group in 2013-14. Issue Analysis In Australia, marketing effort is aimed at attracting and maintaining sufficient numbers of regular, volunteer blood donors in the under-represented age group of 18 to 24 year-olds. It is essential that the Australian Red Cross Blood Service ensures are reasonable and safe blood supply throughout the year. Each week, at least 27,000, blood donations, are required to assist people with serious blood illnesses (e.g., cancer, blood diseases), surgical patients (e.g., open heart surgery, burns), kidney disease patients, pregnant women and traumatic accident patients (Australian Red Cross Blood Service, 2013). Only a relatively small percentage of the eligible population within the 18-24 year-ol d age group donates blood on a regular basis. Furthermore, eligible donors often lapse in their blood donating behaviour after their blood donation. Marketing Strategy Arranging for a blood donation campaign is a challenging task and requires intensive market study, planning and psychological analysis of the blood donors. An effective marketing strategy needs to be developed to ensure the smooth functioning of the blood donation campaign. Marketing Objective To encourage blood donation among individuals aged between 18 to 24 years old from the period 01 July 2013 to 30 June 2014. Budget Allocation The allocated budget for the blood donation campaign would be AUD20 million which would be required to cover the research process, media, medical equipments, advertising

Post-Traumatic Stress Disorder in Iraq Veterans Essay Example for Free

Post-Traumatic Stress Disorder in Iraq Veterans Essay Post-traumatic Stress Disorder is a condition characterized by excessive fear, helplessness, or horror resulting from an experience of excessive trauma. Its symptoms include persistent relapse of the traumatic experience, avoidance of stimuli related to the trauma, lack of general responsiveness, and lingering symptoms of heightened autonomic arousal (Long, 1995). The State of Post-Traumatic Stress Disorder  All these symptoms must manifest themselves for over a month, and the condition must bring about a clinically significant pain or impairment in social, occupational, or other important aspects of functioning (Long, 1995). According to a study conducted by the Pentagon, almost one out of ten American soldiers who went on a tour of duty in Iraq suffered post-traumatic stress disorders (PTSD) after seeing a dead comrade or taking part in combat. The findings of the study could trigger a budget battle in Congress over the health care of veterans (Strong, 2006). The survey, which involved 222,620 Army and Marine soldiers coming home from Iraq, 16,318 from Afghanistan, and 64,967 from other places, revealed that over 1/3 of American soldiers received psychological counseling immediately after coming home from Iraq (Strong, 2006). Published in the Journal of the American Medical Association, the report revealed that nineteen percent of the returnees satisfied the â€Å"risk criteria for a mental health concern† of the military which is higher than the 11. 3% and 8. 5% of those who returned from Afghanistan and other deployments, respectively (Strong, 2006). According to Dr. Charles Hoge, who co-authored the study and serving as a colonel at the Walter Reed Army Institute of Research, said that the findings of the research did not come as a surprise to them since the military is implementing a new mental health evaluation program for returning soldiers which encourages them to seek medical help early to avoid any serious complications in the future (Strong, 2006). Post-traumatic stress disorder was likewise experienced by soldiers who were deployed to Vietnam. Administered in 1990, the National Vietnam Veterans Readjustment Study conducted by The Research Triangle Institute contracted by the Veterans Affairs Administration, the research revealed that 31 percent of the soldiers deployed to Vietnam which translates to 1 million troops experienced PTSD after their return (Satel, 2004). Psychiatric reports attached to the study showed that 12 to 15 out of every 1000 soldiers succumbed to psychiatric disorder. If the 1990 research is accurate, the number of Vietnam War veterans who suffered from PTSD increased vastly in post-war era (Satel, 2004). In the Pentagon study, 80 percent of those who was diagnosed with PTSD said that they saw their comrades getting killed or wounded or took part in combat and shot their weapon. Among those who did not experience PTSD, half participated in combat and experienced violence (Strong, 2006). The Effects of Post-Traumatic Stress Disorder According to Judith Broder (2008), psychiatrist and founder of the Soldiers Project, a volunteer organization geared towards treating war veterans for free, the excessive trauma as well as the fear of getting almost killed are common signs of post-traumatic stress disorder. It is quite understandable as soldiers are sent to unfamiliar territory and will always find themselves in a dangerous situation and tends to be cautious all the time. For most soldiers who are deployed in Iraq making the transition to a peaceful life after months or years of being in action can be challenging (Terzyan, 2008). The reason for the growth in post-traumatic stress disorder is not only because troops have now become more aware of the condition but also due to the extended separation from their families and secured conditions. Likewise, troops are prone to PTSD because the nature of their job demands their being exposed to life-threatening and stressful conditions (Terzyan, 2008). Treating Post-Traumatic Stress Disorder Contrary to what many people think, treating post-traumatic stress disorder in war veterans can be quite complicated. There is evidence that proves that taking any kind of medication is not as effective in war veterans as it is in ordinary citizens, and there is minimal research on antidepressants for combat troops (Spollen Labbate, 2008). A small study used fluoxetine in treating post-traumatic stress disorder in war veterans. The findings showed minimal improvements in veterans than civilians. A similar study this time using sertraline yielded the same result (Spollen Labbate, 2008). Psychological and social intervention may be the first choice when it comes to veterans with PTSD. In some instances, they are more valuable interventions than medication. Building trust between patient and provider is the initial step in the conduction of treatment. However, establishing such connection can be difficult with patients who has suffered traumatic stress (Reeves, 2007). Treating Iraq veterans with post-traumatic stress disorder poses a real challenge to primary care providers. For many patients, an early alternative would be to visit a Veterans Affair (VA) medical facility. The United States Department of Veteran Affairs has trained physicians in the field of PTSD and Iraqi veterans coming home are qualified for treatment (Reeves, 2007). Conclusion Post-traumatic Stress Disorder (PTSD) is a condition characterized by excessive fear, helplessness, or horror resulting from an experience of excessive trauma. Its symptoms include persistent relapse of the traumatic experience, avoidance of stimuli related to the trauma, lack of general responsiveness, and lingering symptoms of heightened autonomic arousal. According to a study conducted by the Pentagon, almost one out of ten American soldiers who went on a tour of duty in Iraq suffered post-traumatic stress disorders (PTSD) after seeing a dead comrade or taking part in combat.

Externalities of Smoking

In the paper I’m going to discuss the externalities of second-hand smoke. Externalities refer to all costs or benefits of a market activity borne by a third party. It’s also the difference between the social and private costs (benefits) of a market activity. When economic agents are not directly involved, negative externalities can exist, such as pollution. Second-hand smoke is a health hazard at any level (Essentials Of economics, Bradley R. Schiller). It’s to be said that smoking bans are the only way to protect nonsmokers.Although many states and hundreds of cities have passed smoke-free laws, more than 126 million Americans ages 3 and older continue to be exposed to secondhand smoke. Nearly 50,000 nonsmokers die from the secondhand smoke each year. Nonsmokers exposed to secondhand smoke at home or work increase their risk of heart disease and cancer. Brief exposure to smoke, damages cells, beginning a process that can lead to cancer, and increase the risk of blood clots (USA today: June 28, 2006).Secondhand smoke kills 46,000 adult nonsmokers from heart disease, 3,000 nonsmokers from lung cancer, and 430 newborns from sudden infant death syndrome. In children it causes 790,000 ear infections, 200,000 episodes of asthma, at least 24,000 low birth weight or preterm deliveries. When non-smokers are exposed to secondhand smoke it’s called involuntary smoking or passive smoking. Regardless if you’re smoking or not, if you’re around someone who is smoking you’re taking in nicotine and other toxic chemicals just like smokers do.The workplace is a major source of secondhand smoke exposure for adults (USA today: June 28, 2006). Secondhand smoke meets the standard to be classified as a potential cancer-causing agent by the Occupational Safety and Health Administration (cancer. org). Separating smokers from non-smokers, cleaning the air, and ventilating the building cannot prevent exposure if people still smoke inside t he building. Most people can be exposed in public places such as restaurants, shopping centers, public transportation, schools, and daycare centers.Some businesses seem to be afraid to ban smoking, but there is no proof that going smoke-free is bad for business. Public places where children go are a special area of concern (cancer. org). Making your home smoke free is healthier for your family. Secondhand smoke imposes significant costs on nonsmokers and society, according to a recent society of Actuaries study that concluded the annual cost of excess medical care, mortality and morbidity from secondhand smoke exposure in the U. S is approximately $ 10 billion(18 Aug 2005).The study also found that medicals costs for caring for people exposed to secondhand smoke have reached more than $2. 5 billion (medicalnewstoday. com). All the money you spend on cigarettes is just going to the company that makes them. So you’re giving this company all this money to just smoke a cigarette. On average most people pay about close to seven dollars for a box of cigarettes. Not only is this harmful to you, but its as harmful to the people around you. When you smoke in front of someone their inhaling all the chemicals that are carried In that one cigarette.So in conclusion this affects the economy so much, because people who don’t even smoke have to pay for all types of medicals bills. Just from getting secondhand smoke from others. I myself don’t think they should banned smoking. But there should be sections in public places which are meant for smokers. Some people can’t just stop smoking no matter what they do. So at the same time we have to respect their needs. And their needs are nicotine.

Méliès’s Trip to the Moon Essay

The film opens with a gathering of academics in a lecture hall. They have robes, beards and pointed hats. They are standing at first in ranks in the room, five more men join them and are given telescopes by female servants. The leader enters and assumes a position at a blackboard on the left where he draws an image of the Earth and the Moon and a bullet-shaped craft landing on the Moon. They all being discussing or arguing about the project. The technique used for acting is based on what one might see acted out in the theater with no modern cinematography such as close-ups or zooms are used to focus the attention on a particular character. All the characters appear onstage and if there is any focus on a certain action is done through theatrical technique such as the females marching out and handing out telescopes and leaving. When the main character, seeming like a professor comes in the group sort of comes to attention and stand still at first while the professor speaks and draws on the board. One’s attention’s shifts to the group again as they discuss and argue with over-large gesticulations in this silent film without written inter-titles. It is a silent stage drama recorded on film, else it would be mime theatre. The film’s scene changes almost like a shift of scene in the theatre. There is a very fake-looking space capsule that is being worked on and some of the astronauts try out the interior. There is a moment when someone falls into a shallow barrel. Possibly, this was meant to be a comic touch which would be at home later in vaudeville. There is no camera movement. It is as if one had a good seat at the theatre and watching a series of tableaux vivantes. The film owes much more to the stage and picture books than to any already-developed film technique. The subsequent boarding of the space-bullet on the left with the cannon on the right looks especially fake and hand-drawn. There is little aim at a believable set and much over-acting: doffing their hats and so on to an imaginary group of spectators, actually us who are watching the living theater more than a film by today’s standards. After the firing of the cannon, there occurs the use of something like special effects where the Man in the Moon, framed by clouds comes closer to the viewer and has human like expressions which show the space vehicle hitting him in the eye. It is a real human looking like he has whipped cream on his face.

Aluminum or Aluminium Alloys - List

Aluminum or Aluminium Alloys - List An aluminum alloy is a composition consisting mainly of aluminum to which other elements have been added. The alloy is made by mixing together the elements when aluminum is molten (liquid), which cools to form a homogeneous solid solution. The other elements may make up as much as 15 percent of the alloy by mass. Added elements include iron, copper, magnesium, silicon, and zinc. The addition of elements to the aluminum gives the alloy improved strength, workability, corrosion resistance, electrical conductivity, and/or density, compared with the pure metallic element. Aluminum alloys tend to be lightweight and corrosion resistant. List of Aluminum Alloys This is a list of some important aluminum or aluminium alloys. AA-8000: used for building wire per the National Electrical CodeAlclad: aluminum sheet made by bonding high-purity aluminum to a high strength core materialAl-Li (lithium, sometimes mercury)Alnico (aluminum, nickel, copper)Birmabright (aluminum, magnesium)Duralumin (copper, aluminum)Hindalium (aluminum, magnesium, manganese, silicon)Magnalium (5% magnesium)Magnox (magnesium oxide, aluminum)Nambe (aluminum plus seven other unspecified metals)Silumin (aluminum, silicon)Titanal (aluminum, zinc, magnesium, copper, zirconium)Zamak (zinc, aluminum, magnesium, copper)Aluminum forms other complex alloys with magnesium, manganese, and platinum Identifying Aluminum Alloys Alloys have common names, but they may be identified using a four-digit number. The first digit of the number identifies the class or series of alloy. 1xxx - Commercially pure aluminum also has a four-digit numerical identifier. Series 1xxx alloys are made of 99 percent or higher purity aluminum. 2xxx - The principal alloying element in the 2xxx series is copper. Heat treating these alloys improves their strength. These alloys are strong and tough, but not as corrosion resistant as other aluminum alloys, so they are usually painted or coated for use. The most common aircraft alloy is 2024. Alloy 2024-T351 is among the hardest of the aluminum alloys. 3xxx - The main alloying element in this series is manganese, usually with a smaller amount of magnesium. The most popular alloy from this series is 3003, which is workable and moderately strong. 3003 is used to make cooking utensils. Alloy 3004 is one of the alloys used to make aluminum cans for beverages. 4xxx - Silicon is added to aluminum to make 4xxx alloys. This lowers the melting point of the metal without making it brittle. This series is used to make welding wire. Alloy 4043 is used to make filler alloys for welding cars and structural elements. 5xxx - The principal alloying element in the 5xxx series is magnesium. These alloys are strong, weldable, and resist marine corrosion. The 5xxx alloys are used to make pressure vessels and storage tanks and for various marine applications. Alloy 5182 is used to make the lid of aluminum beverage cans. So, aluminum cans actually consist of at least two alloys! 6xxx - Silicon and magnesium are present in 6xxx alloys. The elements combine to form magnesium silicide. These alloys are formable, weldable, and heat treatable. They have good corrosion resistance and moderate strength. The most common alloy in this series is 6061, which is used to make truck and boat frames. Extrusion products from the 6xxx series are used in architecture and to make the iPhone 6. 7xxx - Zinc is the principal alloying element in the series starting with the number 7. The resulting alloy is heat-treatable and very strong. Important alloys are 7050 and 7075, both used to construct aircraft. 8xxx s include 8500, 8510, and 8520. 9xxx - Presently, the series starting with the number 9 is unused. What Is the Strongest Aluminum Alloy? Manganese added to aluminum increases its strength and yields an alloy with excellent workability and corrosion resistance. The highest strength alloy in the non-heat-treatable grade is alloy 5052. Aluminum Alloy Classification In general, the two broad categories of aluminum alloys are wrought alloys and casting alloys. Both of these groups are subdivided into heat-treatable and non-heat-treatable types. Around 85% of aluminum is used in wrought alloys. Cast alloys are relatively inexpensive to produce because of their low melting point, but they tend to have lower tensile strengths than their wrought counterparts. Sources Davis, J.R. (2001).
