The Philippines And The World Market Essay free essay sample
, Research Paper The Philippines and the World Market The Philippines is considered to be one of the most westernized states in Asia. It has strong ties to the United States and the United States. In fact, It is the lone charter member of the U.N. in all of Southeast Asia. The United States has a really close relationship with the economic system and civilization of the Philippines. For case, Filipinos have a strong bitterness toward communistic states. During the cold war, the Philippines supported America by systematically being hostile toward communist states, and did non maintain diplomatic dealingss with the Soviet Union or any other communist province. The United States is the largest foreign consumer of Philippine merchandises. In many ways the endurance of the Filipino economic system depends on the united States. We purchase about all of the sugar exports, most of the coconut oil, embellishment, at least half of the base metals, and a 4th of the timber. We will write a custom essay sample on The Philippines And The World Market Essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The United States supplies most of the Philippine imports of machinery, dairy merchandises, cotton, documents, drugs, cars and much or the crude oil merchandises. Although states like Japan, Canada Australi a, and New Zealand are acquiring more and more involved in trade with the Philippines, America remains to be the Philippines most of import trading spouse. When America acquired the Philippines and established free trade in 1909, the economic system of the islands was tied to that parent state. As a consequence, the Philippines became about wholly dependent upon United States markets. Therefore, America has had a strong influence on non merely the economic system of the Philippines, but besides the political relations of it. The United States established a public instruction system in the Philippines in the early 1900? s. Although they were non American schools they had many similarities. American instructors were used every bit good as American books. The instructors besides taught in English. The Filipino authorities is even designed after the American system and dedicated to democratic procedure. All in all America has become a really strong influence on the Philippines. Even though the exterior program was to construct up the Filipino economic system and authorities so allow them hold their independency, it seems obvious there was a deeper program to Americanise and economically command the county. Follow the money. .

Bottle Gourd Domestication and History
Bottle Gourd Domestication and History The bottle gourd (Lagenaria siceraria) has had a complex domestication history written for it over the past twenty years. However, recent DNA research suggests that it was domesticated three times: in Asia, at least 10,000 years ago; in Central America, about 10,000 years ago; and in Africa, about 4,000 years ago. In addition, the bottle gourds dispersal throughout Polynesia is a key part of evidence supporting the possible Polynesian discovery of the New World, circa 1000 AD. The bottle gourd is a diploid, monoecious plant of the Cucurbitacea. The plant has thick vines with large white flowers that open only at night. The fruit comes in a large variety of shapes, selected for by their human users. The bottle gourd is primarily grown for its fruit, which when dried forms a woody hollow vessel that is suitable for containing water and food, for fishing floats, for musical instruments and for clothing, among other things. In fact, the fruit itself floats, and bottle gourds with still-viable seeds have been discovered after floating in seawater for more than seven months. Domestication History The bottle gourd is native to Africa: wild populations of the plant have recently been discovered in Zimbabwe. Two subspecies, likely representing two separate domestication events, have been identified: Lagenaria siceraria spp. siceraria (in Africa, domesticated some 4,000 years ago) and L. s. spp. asiatica (Asia, domesticated at least 10,000 years ago0. The likelihood of a third domestication event, in Central America about 10,000 years ago, has been implied from genetic analysis of American bottle gourds (Kistler et al.), Domesticated bottle gourds have been recovered in the Americas at sites such as Guila Naquitz in Mexico by ~10,000 years ago. Bottle Gourd Dispersals The earliest dispersal of the bottle gourd into the Americas was long believed by scholars to have occurred from the floating of domesticated fruits across the Atlantic. In 2005, researchers David Erickson and colleagues (among others) argued that bottle gourds, like dogs, had been brought into the Americas with the arrival of Paleoindian hunter-gatherers, at least 10,000 years ago. If true, then the Asian form of the bottle gourd was domesticated at least a couple of thousand years before that. Evidence of that has not been discovered, although domestic bottle gourds from several Jomon period sites on Japan have early dates. In 2014, researchers Kistler et al. disputed that theory, in part because it would have required the tropical and subtropical bottle gourd to have been planted at the crossing place into the Americas in the Bering Land Bridge region, an area far too cold to support that; and evidence for its presence in the likely entryway into the Americas has yet to be found. Instead, Kistlers team looked at DNA from samples in several locales in the Americas between 8,000 BC and 1925 AD (included Guila Naquitz and Quebrada Jaguay) and concluded that Africa is the clear source region of the bottle gourd in the Americas. Kistler et al. suggest that the African bottle gourds were domesticated in the American Neotropics, derived from seeds out of gourds which had drifted across the Atlantic. Later dispersals throughout eastern Polynesia, Hawaii, New Zealand and the western South American coastal region may have been driven by Polynesian seafaring. New Zealand bottle gourds exhibit features of both subspecies. The Kistler study identified the Polynesia bottle gourds as L. siceria ssp. asiatica, more closely related to Asian examples, but the puzzle was not addressed in that study.

Human Resource Management Essay Example | Topics and Well Written Essays - 750 words - 2
Human Resource Management - Essay Example Khan had gone for an interview with the organization wearing the hijab, which did not prevent her from being hired as she had agreed to wear it if it matched the company colours. However, a higher-ranking manager spotted her in one and suspended her immediately after which he went ahead and dismissed her from work. In the judgement, US district attorney Yvonne Gonzalez Rogers of Oakland argued that Abercrombie had granted exemptions since 2005 which allowed employees to wear Jewish yarmulke, a baseball cap among other exemptions she went ahead to argue that Khanââ¬â¢s attire had not in any way affected the business. The attorney found out that Abercrombie had violated the religious rights of Khan and therefore awarded her damages to the tune of 48, 000 dollars. In addition, the organisation was required to permanently drop any ban that it had in respect to headscarves. In the settlement, the organisation was also required to accommodate different religious beliefs and practises as long as it did not suffer any undue hardships. Worker absenteeism costing the economy billions Absenteeism among workers has caused most of the economies in the world to lose billions of dollars. This absenteeism ranges from short offs to long leaves from work. The rates of absenteeism differs between different working conditions and industries, for instance workers who are on full time employment terms have a higher rate of absenteeism as compared to those that are working on contractual basis. In addition, government employees are more likely to be involved in higher levels of absenteeism as compared to people working in the private sector. In Canada, the level of absenteeism among full time workers is an average of 9.3 days, which represents almost two full working weeks. The trend of absenteeism is more rampant among full time government employees who are estimated to be absent from work about 12.9 days a year and private sector workers who are absent from work 8.2 days a year. It is estimated that in 2012, the Canadian economy lost about 16.6 billion US dollars due to workers absenteeism. This trend is likely to continue as the workers age if it is not properly handled. A major shortcoming in dealing with the problem of worker absenteeism is that despite of the economic implications that it has on the Canadian economy, less than half of the employees track down the number of absent days that employees have. Despite it being hard to compare the levels of absenteeism between countries, the levels of absenteeism in Canada are high compared to those in United States of America and United Kingdom. Age discrimination in the workplace in Michigan Age discrimination in the work place occur when the employer makes employment related decisions on the basis of age or treats the employees differently due to their age. in Michigan, several age discrimination practises are illegal, for instance, sacking, hiring or refusing to hire an individual based on his age is con sidered illegal, treating employees differently based on their age in relation to promotions, wages, knowledge advancement opportunities, benefits or training is also not allowed (Hulett, 2011). In addition, when an employer advertises a vacancy in his organisation stating preferences for people of a certain age bracket is also considered as an illegal age discrimination practise in Michigan. In Michigan, age discrimination

Email Tracking And News Posting Tracking Essay Example | Topics and Well Written Essays - 750 words
Email Tracking And News Posting Tracking - Essay Example They receive messages and forward them to the intermediate systems that indicate the path between the receiver and the sender. Systems facilitate this activity to determine the actual sender of information, however, it ca n be challenging if the founder of messages covers the suspicious emails and news postings. Email tracking involves screening email delivery to the addressee. It enables the sender to know if the intended recipient received the message, but does not show if the email was opened and read (Pappallardo & Ellen 2005). Outlook, Notes, and Eudora are networked software that enable clients interact with the server. Microsoft office outlook develops a read receipt tracking method, which makes the sender access the receipt request option before sending the email. After sending the message, recipients can also bring to the attention of the sender that the email was received and read. Nevertheless, such email applications do not guarantee the sender receipt request. On then ha nd, news postings indicate on the top of the message significant tracks that show the subject header, the sender, date, and dime sent. With such vital information, tracking of group news becomes easier compared to emails. Postings are public and can be accessed by a significant number of people. Emails are private and more personal than news postings since they are addressed to a specific person or group. News postings audience who visit social networking sites such as face book and twitter. News postings are bulletins for everyone in the network to see. They are useful because they inform friends in the network service without resorting to sending messages individually. However, tracking news becomes challenging since posts are deleted affected ten days while emails are stored in the server for future reading and reference. Therefore, tracking of emails have been shown to be easier than postings. When conducting email tracking, one can use the IP address that the user assigned, whi ch will show the time and date the message was sent (US-CERT 2003). Lastly, in email tracking, one can investigate on behalf of the victim, by sending the original message through copy mailing. At this point, one can send the message as an attachment because for warding replaces the suspectââ¬â¢s information. News postings have group link features that enable the use to sign up until the time when her network shall be back. In networking systems, new postings prove to be the perfect destination for everyone to stay connected. Question 2- IRC crimes The growth of technology has been identified with positive and negative effects. The world has witnessed the abuse of this new system making the society acquire a negative attitude. Child pornography is an ex ample of internet related crime because nude figures are exposed on websites, and when children come across them, they become misguided. Scenes of teenagers involving on sexual acts are posted on the internet. This technology can be accessed by anyone regardless of their age. Such websites have chat conversations, which lure children in to immoral conversations that lead to child abuse. Secondly, carding and phishing describe how fraudsters operate in small and secret channels. They code their messages to prevent people who may come across, and discover their network. Therefore, to track carding and phishing, one should have a peculiar access to IRC network servers. Internet related crime is overlooked when computer crimes come in to discussions. It is seen as a less dangerous compared to other types of crimes. Crimes committed on computers become challenging to track because the society lack s information on this issue. Chat rooms have been made to facilitate chatting and communicating globally (Smith 2004).

Illegal Downloading: Good Or Bad?
Illegal Downloading: Good Or Bad? There have been many arguments on whether illegal downloading is a serious problem or not. Illegal downloading isnt that much of a problem if you take the time out to research into it. Sources have shown that illegal downloading actually promotes and helps artist more, it helps people become more diverse in music genres, artist illegally download music as well as their fans, and that there is zero to no evidence that free online music financially harms anyone. These and many more is just the tip iceberg on the arguments that are for illegal downloading, but for now where did illegal downloading all begin? The history of commercial music distribution is a recent one.(Miller, Web). Music distribution started up about the 1800s when the idea of sheet music was thought of. Later after that during the 1930s, people of the middle class had pianos. They would usually go to the local store, buy sheet music of their favorite artist during that time, and play it at their homes. Soon after there was the invention of the phonograph by Thomas Edison which enabled artist to widely distribute their music. The music was first created on wax cylinders and then vinyl discs. During this time there were about 150 companies creating records. Over time, the record industry evolved from 78 RPM discs to 45 RPM singles to 33 1/3 RPM long playing (LP) albums, and then to 8-track tapes (remember them?) And recorded audiocassette, and then to digital compact discs and finally to downloadable and streaming digital tracks.(Miller, Web). Quality had greatly increased with this evolution and so did the distribution. It was pretty obvious that these recordings could be duplicated, but it wasnt as easy back then. The only things that were known were home wire recorders and discs cutting machines. Not all people knew how to use these devices at the time though. What really started making things easy was the invention of the reel to reel tape recording in the 1950s and the audiocassette recorders in the 1960s. The only problems with these were that the audio grade of copied music was somewhat horrible. It wasnt until the digital era started that we could make extremely good copies of music due to CDs and your computer. Then when the internet came along downloading music became simple for anyone to be able to download any type music for free. (Miller, Web). Napster, which started in 1999, was the first hugely popular music file-sharing services. It was shut down by court order in 2001.(Hamilton, 90). Now a days most music downloading is done by college students. (Jambon, Web). One of the main arguments of the opposing side says that it harms artist by taking money from them, but this is the exact opposite. In a survey shown by opposing viewpoints there were only about 12 percent of artists thought that illegal downloading hurt them. Most of the artists were not convinced that illegal downloading is doing any economic harm. Whats worth noting is that higher educated artist in particular believed that file-sharing is doing them no harm.(Opposing Viewpoints). Also majority of the artist thought that illegal downloading helped promote them. About 50 percent of the artists believe strongly that illegal downloading helps get their work known better in public. There was only about 5 percent who thought the other way around. In particular the younger artists ( Illegal downloading also helps artist by helping people become more subjected to new genres of music. Having the easy accessibility of mp3s means that more people will be listening to different types of music that they havent heard before, and this informs them more on music as a whole. Artists really have nothing to worry about when it comes to losing money in the music industry. From research artist have also been known to download music illegally themselves. the Dutch Government announced plans to outlaw downloading of all copyrighted material and measures to make it easier to block websites that facilitate copyright infringement. An interesting, particularly since a survey they published on the same day shows that artists views on file-sharing are not all that negative.(Opposing Viewpoints). They began a huge survey in order to find out more about the view of artist on the topic of piracy, DRM the digital rights management: technologies that limit access to digital content), and similar opportunities and challenges they had faced in the digital era. The questions that were asked in the article were answered by about 4,000 artists of all ages, which included musicians, filmmakers, authors and photographers. When the results had come out, there was in unparalleled look into the state at which the artists stood on the subject. One of the results that stands o ut directly is that artist are pirates too.(Opposing Viewpoints). While not all of them were pirates, there was a good amount of them that were. About 22 percent of the surveyors responded saying that they had downloaded copyrighted works without the owners permission in the last 12 months. Another 71% told the researchers they hadnt downloaded anything without permission during this period, and the remaining 7% didnt know, or didnt want to answer the question.(Opposing Viewpoints). There was another question ask to the surveyors who had recently owned up to downloading other peoples copyrighted works. These results had shown that music was the most downloaded media type, with 80 percent from music, 40 percent for movies and 5 percent for e-books and games (Opposing Viewpoints). So as well the fans downloading illegally, the artist were no different. Lastly there really is zero to no evidence when it comes to financially harming artist. If you think about, the music industry should be rejoicing at this new technological advance. Heres a foolproof way to deliver music to millions who might otherwise never bought a CD in a store.(Aksomitis,16). There is an exceptional amount of cross-marketing. The cost is extremely low and there is no shipping. The RIAA may be right about their being a lot changes in the music industry, but at the same time there still are a good amount of labels left. Well turn into Microsoft if were not careful, folks, insisting that any household wanting an extra copy for the car, the kids, or the portable CD player, has to go out and license multiple copies.(Aksomitis, 16). People as artist are the ones who have the ear of the masses, and thats who should be trusted. Most of the shame should not be brought on the fans and the people, but on the bad state of the industry of recording companies, radio programmer s. There although is some good arguments that states the fans need to organize themselves in order to better their own lives and morals in illegal downloading. This is true but this is one of few true statements that fall under the cons of illegal downloading. In conclusion to this argument, there is some but not a lot of danger when it comes to illegal downloading its actually a good thing. Whether it be helping the artist, artists illegally downloading or any other reason. Illegal downloading is here to stay, and while there all no ways to completely stop it there are always ways to help it. Work Cited Jambon, Marc M., and Judith G. Smetana.

Stem Cell Therapy Essay
Sepulveda Bio. Anthro. Tues 6-9 Cell Replacement and Stem Cell Therapy to Treat Neurodegenerative Disease Stem cell therapy is being used to treat neurodegenerative diseases such as amyotrophic lateral sclerosis or ALS, commonly referred to as Lou Gehrigââ¬â¢s disease. The disease itself, new therapies and treatments, along with a cure are currently being studied by universities and stem cell researchers. ALS is a progressive neurodegenerative disease which attacks the neurons in the brain and spinal cord that control voluntary movement, eventually leading to respiratory failure and death (Kamel et al. 2008). The current course of action for a patient with ALS is physical therapy and, if their budget allows, cell replacement therapy. However there is presently no cure and the patient will eventually have respiratory problems and die from the disease. Adult stem cells (ASCs) and blastocyst or embryonic stem cells (ESCs) are being used to treat amyotrophic lateral sclerosis in cell replacement therapy, yet this only slows the degeneration of their neurons (Goldman, Windrem, 2006).Research for both adult stem cell and blastocyst stem cell technologies are the only practical option in approaching a cure or more effective treatment for ALS. Both of these technologies require stem cells, but are challenging to safely retrieve and utilize through the current treatment methods, which is why it is essential to continue to support and fund this research. Cell replacement therapy is currently the only stem cell treatment of neurodegenerative diseases such as ALS, but researchers are trying to find new ways of treating and possibly curing ALS.Cell augmentation using stem cells could be the future of treatment for ALS but scientists are currently working to increase availability of the needed ESCs and ASCs to treat patients using cell replacement therapy. There are three different ways to harvest the necessary stem cells for neuron replacement: growing ESCs in vitro, har vesting stem cells from the brain or spinal cord of a live donor through biopsy, and harvesting from the brain or spinal cord of a donor post mortem (Sohur et. al. , 2006). The goal of treatment of ALS is to slow and eventually stop cell loss progressing to the point of functional impairment.To accomplish this goal, protecting the remaining neurons as well as replacing and augmenting damaged neurons is important. The ultimate goal, to cure ALS, is to fully restore authentic neuronal circuitry or ââ¬Å"full systems reconstructionâ⬠(Ormerod et. al. 2008). Full systems reconstruction would consist of recreating a map of precisely patterned neurons of the correct type using the stem cells to send projections to the appropriate field within the brain. The cure seems virtually impossible with the technology currently available, but recreating neurogenesis may be possible in the future.Adult stem cell harvesting is difficult and costly when retrieving the stem cells needed to treat neurodegenerative diseases from brain matter or spinal fluid. Neurons are very specific cells in the brain and spinal cord and possess a special set of neurotransmitters depending on their function; this poses problems when harvesting ASCs (Zhang et. al. , 2006). The ASCs needed to treat ALS must be able to specialize and replace degenerating neurons affected by the disease. This procedure would not be possible without using stem cells to replace the damaged and degenerating neurons.However a problem associated with ASCs is rejection of foreign cells when transplanting ASCs taken through biopsy from a donor. Although biopsy from the patient receiving treatment is an option, the ASCs required come from the brain or spinal cord and can be very dangerous to harvest this way. Adult neural stem cells can be harvested from brain tissue, either from a deceased donor or through biopsy, and then grown in a culture (Ormerod et. al. , 2008). ASCs will not expand nearly as much as ESCs in cultu re and will differentiate into a limited number of neuron types.When using ESCs, which conform to the necessary specialized type of neurons, the lack of flexibility encountered in the ASCs is eliminated. Human embryonic stem cells (ESCs), however difficult to harvest initially, will multiply greatly when grown in culture. The ESCs are generated by in vitro fertilization and grown into the blastocyst stage before harvesting. The advantages of ESCs are boundless; the results of the therapy would not be obtainable without use of the stem cells to replace the damaged cells.The ease and frequency with which ESCs can be expanded in culture is a significant advantage over ASCs. Growing such high numbers of stem cells in this fashion can prove problematic though, while the cells reproduce indefinitely they become more susceptible to mutation and may cause tumors following transplant (Ormerod et. al. , 2008). Thus, a challenge rises to differentiate the cells fully before transplant or to gr ow many more cultures from different donor eggs, which are difficult and expensive to receive.ESCs are more easily specialized into neurons, oligodendrocytes, and glia needed to treat ALS than ASCs; but the possibility of tumors forming in the patient along with the cost and complication of creating new chains of blastocysts from donor eggs pose a disadvantage of using this technology (Ormerod et. al. , 2008). Taking into consideration ESC technologyââ¬â¢s advantages and disadvantages, it is equally as viable an approach to a cure for ALS as ASC technology. ALS is an extremely destructive disease which unfortunately plagues a large population.ALS is difficult to treat because it is a neurodegenerative disease and requires brain surgery and neuron replacement. Both adult stem cell and embryonic stem cell therapies have potential to increase the quality of life for patients with ALS but they both have their own individual inherent risk that must be taken into account by the patient and doctors when choosing a stem cell therapy method. Donors are few and far between and the necessary cells are very specific for this particular procedure.Through an increase in research and development of new ways to multiply and store stem cells, along with an increase in donors, the road toward a cure will be a short one. Hopefully in the future the treatment will become easier, less costly, and less dangerous for the patient. Works Cited Larsen CS. 2010. Essentials of Physical Anthropology: Discovering Our Origins.

Realtionship Between the Media, Public Perceptions of Crime and Police Essay
Does the media and the amount of exposure to specific news media affect fear of crime? This question is examined in a survey with data collected from three universities in the United States and one in Canada; The Impact of Media on Fear of Crime among University Students: A Cross-National Comparison, goes over the results. Itââ¬â¢s believed that fear in itself can be debilitating leading to harmful social outcomes. Vincent Sacco believes there are three dimensions to fear of crime: cognitive, emotional and behavioral. Cognitive looks at a how a person assesses their likelihood of being victimized. Emotional is how someone feels about crime, and behavioral is a personââ¬â¢s response to fear of their perceived likelihood of being victimized. However, in 2011, it was argued ââ¬Å"that fear of crime ought to be conceptualized by distinguishing between generalized anxieties and more concrete episodes of fear, as well as by differentiating effects of everyday worries and anxietiesâ⬠(Kohm, Waid-Lindberg, Weinrath & Shelley, 2012). This theory ââ¬Å"is thought allow for better understanding of how people are motivated to protect themselvesâ⬠(Kohm, Waid-Lindberg, Weinrath & Shelley, 2012). Despite a decrease in crime rates, citizens of both the United States and Canada still have a high fear of being victimized. One theory suggests that increased fear is a direct result of an individualââ¬â¢s perception of the risk to being a victim. This can occur because of oneââ¬â¢s past victimizations or through media exposure of crime also known as indirect victimization. Individuals learn of local crime, national crime and even world-wide crime events through media sources: TV, newspapers, and internet. In 2007, the United Nations Crime Victims Survey (ICVS) showed that the United States reported the second lowest level (16%) of fear of being victims of a burglary compared to Canada who reported higher levels (25%) of fear, even though crimes rates had declined since 1989. Secondhand information (news sources) raises fear and beliefs that victimization is likely, in turn individuals become indirect victims through their fear. The cultivation theory suggests that when violent crimes stories increase so does the fear of crime. Similar to the cultivation theory, the substitution perspective states that individuals with no history of victimization will have increased fear of crime with crime related stories. The resonance perspective is just the opposite. It states that the media increases fear when the content is similar to oneââ¬â¢s experiences. These three theories are derived from the indirect victimization model. Most individuals receive crime information from television news reports, where stories on crime are reported twice as often as political news stories. Stories involving multiple victims, use of firearms, as well as certain other crime characteristics is more newsworthy than others. The survey done on Canadian and United States university students showed that local news affected individualââ¬â¢s fears more than world news. Also television news reports affected fear more than other news sources such as newspapers or the internet where people can select which stories they want to read. The nature of a criminal offence and the community context in which the crime occurs determines how a story is reported. An example being, ââ¬Å"smaller suburban and rural areas are more likely to report all homicides while large urban areas may be more selectiveâ⬠(Kohm, Waid-Lindberg, Weinrath & Shelley, 2012). The article states that fear if crime is directly related to demographics factors which include: gender, age, race/ethnicity, and situational factors including any previous victimization, oneââ¬â¢s perception of their risk of being victimized, and concerns about local crime. Even though males experience higher levels of being victimized, women tend to fear crime more because they feel they are able to defend themselves against a physical attack. One study reported that Elderly are more fearful where as another study shows younger individuals are more fearful. Therefore, age as a predictor for fear of crime is inconsistent. The following universities were given a self-administered survey as part of the current study this article was based on: Colorado State University (CSU), University of Texas at Arlington (UTA), and Florida State University (FSU) and one Canadian, University of Winnipeg (UW). The campuses of UTA, FSU and UW are located in higher crime urban areas. In Florida and Texas, violent and property crime rates are higher than the national average. Winnipegââ¬â¢s violent and property crimes rates are also higher than the rest of Canadaââ¬â¢s crimes levels. Criminal Justice or Criminology majors reported a lower fear of crime compared to other majors or students who were yet undecided. The survey also showed that there was a similar rate of concern between both nations; reporting on a scale of 1-10 the average was seven, clearly showing a somewhat high concern for crime. In summary, the findings for the survey are as follows: women, whites, non-criminal justice/criminology majors reported aving more fear of crime. A general concern about crime was relatively the same between the American and Canadian students though Canadians had higher rate of fear for risk of violent victimization and Americans had a higher rate for property victimization. The media plays a substantial role in determining the amount of fear of crime that people hold. This comes from the fact that the media extensively and disproportionately cover crime stories. But how does this affect the publicââ¬â¢s perception of law enforcement? The answer to this question is simple. The media leads people to believe that there is more crime than there actually is. Therefore, the media also plays a role in forming expectations of police. When people think that crime has increased, they more than likely will believe that the police are not doing their jobs. The problem is, is that the media has created a false image of law enforcement. According to Ronald D. Hunter and Thomas Barker (2011), ââ¬Å"the police officers of Hollywood lore are fictional images of stereotypes that have been exaggerated to provide entertainment to a bored publicâ⬠(p. 41). A few examples of entertainment media that depict these false pictures of police are: CSI, NCIS, Law and Order, Criminal Minds, and NYPD Blue. Each and every one of these portray the characters as super-cops that can perform more than just the standard jobs of real life police officers. For example, in CSI the multitude of character can perform investigative tasks as well as tasks involving forensic science. The characters of these shows solve challenging cases using their superior intelligence and expertise. Almost always, the characters solve their case in single day maybe two days. People tend to believe that these fictional images and stereotypes are true and base their perceptions of real life police off these. Aside from entertainment media, the public is also greatly influenced by news media, as previously seen above. According to Hunter and Barker (2011), Depicting the police negatively as misusing deadly force, police prejudice, or police corruption is also newsworthy. The amount of emphasis given to police actions and the mediaââ¬â¢s interpretation of these actions as either proper or improper have a tremendous effect on the publicââ¬â¢s perception of the police. p. 41) Police agencies across the United States; deal with accusations of misuse of force on a daily basis. Justified or not, images of police using force continue to outrage the American public. However, police use of force incidents are often misinterpreted by the community due to the media frenzy twisting facts. The media undermines the authority of the police and reduces the trust that the public has in its police. What is observed in the media is largely carried out to represent police as a whole. In other words, the media magnifies situations and creates an exaggerated perspective that viewers assume is a standard of all police and police organizations as well as crime. Among the different types of stories in the media, negative stories attract a larger audience. What a person reads, hears, and observes in the media largely defines the personââ¬â¢s perception of the police. Whether we recognize the effects of the media or not, our perceptions of this world are heavily influenced by the information we receive from the media. The media constantly surrounds us, frequently informs us, and just as frequently misinforms us. The influence of the media is significant since media could be identified as a primary source in influencing peopleââ¬â¢s perceptions of crime and their perceptions of police. Besides the significant effect on fear of crime, the media has influenced the publicââ¬â¢s attitudes toward police at the same time. News media may be the primary source for the public viewing the police as ineffective and incompetent. Studies have highlighted the powerful influence of mediaââ¬â¢s news coverage, there are solid justifications for us to examine the links between fear of crime and how crime news coverage influences the publicââ¬â¢s attitudes toward police efficiency.
