How Does Deforestation Impact Birds?

How Does Deforestation Impact Birds? INTRODUCTION This assignment is based on the impact of deforestation on bird communication. Basically, there are two ways in which birds communicate, that is by powerful sight and vocal sound. They also have an important hearing also since they would have to different sounds produced by their own kind. Hearing is actually affected by noise produced from their environment. Because they have to fly all the time their vision has to be very active hence, they are well protected by nictating glands. They dont have binocular vision and this permit them to view all round vision. These well developed senses help birds to live in their habitat without much disturbance since they detect change quickly and migrate to safer grounds. Deforestation on bird Communication It is stated by (Raven 1988) that two-thirds of the worlds species are found in the tropical rainforest. Due to advance technologies and the demands of the worlds population for adequate survival there has been rapid deforestation increase globally that has resulted in extinction of species. Since most species are not discovered as yet, an accurate record on the loss of species may not be present. Only the ones registered under the IUCN will be accounted for. Generally, the total number of species lost globally will be difficult to retrieve rather than species found in a given region. Species that are not endemic will become threatened/endangered easily due to the fact that they havent yet be rediscovered. In todays world deforestation has made a great impact on bird communication by influencing their habitat and lifestyle simultaneously hence, emphasis is being placed to rectify the forthcoming effect on this outcome. Deforestation is known as the removal or destruction of large areas of rainforest and vegetation to fulfill the needs of the population. More than 80% of the earths natural forest have been removed already (national geographic). This activity is carried out by loggers who see this as a job opportunity since, it is being enhanced into lumber used for construction and decorative purposes. Loggers do this on a large scale without allowing the forest to revive. Farmers clear natural vegetation by the common slash and burn method, among others for agricultural purposes in which they gain an income and consume for survival. When the soil becomes depleted of nutrients they clear another area and leaves the former to erode away rather than replant. Natural disaster also plays a part in deforestation, some parts in the US have extensive forest fires that removes forest lives at extreme temperature. Forested areas is being exploited by policy makers to allocate housing for the growing populati on and mining activities to provide jobs for individuals. Construction of dams to maintain a affordable lifestyle for humans have also lead to deforestation and removal of biodiversity for comforting one population neglecting the others. Because of these activities other organisms has to pay the price by being endangered. There will be a reduction of biodiversity since their habitat is destroyed and those who can adapt very quickly will have no problem. Flooding of ecosystem will take place due to erosion of soil and no vegetation to infiltrate water hence, water table will be lowered. Limited space will be provided for adapted animals to share so their foraging activities will be reduced along with food supply. Drought will be more common since temperature will rise, surface water and that of plants will not be available for evaporation hence, amount of rainfall will be reduced. Lastly, there will be an increase in greenhouse effect which leads to global warming. Stated in NATIONAL GEOGRAPHIC article â€Å" Trees are natural consumers of CO2 which is one of the greenhouse gas that contributes to global warming by building up in atmosphere. Destruction of trees remove C-sink, release more CO2 by tree burning and decomposition.† Picture below shows large scale deforestation. Bird communication basically when a bird sings to claim a personal territory (Dr. Lee). They  tend to mark a particular property in a particular place which they need to do to show ownership among species. The sound is produced by their vocal organ or syrinix located between the junction of their trachea and bronchi. It is used as a communicatory device and also as body language communication to suit their environment and various situations in reply to their lifestyle and ecological behaviour. These include their feeding and foraging behaviour, they require large space among species to gain access to food. Hence, they sing to mark their territory of food and give indication for colleagues to feed. They would want no intruder and tend to extend their territory for alternative food supply. They give a warning call when they sense danger and also make sounds to evade predators. In some cases they use silence as a warning call so they wouldnt be detected by predators e.g. hawk. During flocking and social behaviour sound is needed to communicate among themselves and even others, in fighting and marking territory, courtship and mating, in nesting and parental behaviour and finally, in the display of male dominance. All these behavioural pattern requires a different sound to distinguish what sort of situation they are in before one can actually render assistance. Birds live conspecific in their habitat, by doing so they create a niche that would benefit them in every possible way such as easy feeding access, a range to forage in and a habitat they could call their own. The range would provide birds with food so that there will be no need for them to waste energy to acclimatize to a new source hence, feeding becomes accessible anywhere, anytime in that particular habitat unless there is disruption. Since their metabolic rates are high they would require a large amount of food hence, they have to indulge in foraging activities to supply themselves. After constantly ex ploiting a habitat they would have to adjust to new food sources or find other resources, thus a new habitat will be selected as long as they can survive efficiently. Thereby, more large spaces becomes available for them to graze and procreate. Deforestation entails the complete displacement of bird species or habitat loss by the large scale removal of canopy, trees and vegetation. These places provide a source of shelter and food for birds. In the trees most birds dwells especially when humidity is low, they rest and cool down in trees. In this thick vegetation a wide range of shade is provided hence, the area would have a lot of other wildlife that is used as s source of food for birds so they wouldnt have to fly long distances in search of food. There will also a continuous supply of of plant matter that specific birds feed on thus, these components will provide a community of bird species to inhabit this region. The removal of trees decrease the food supply of birds and they would have no place to call their habitat. There will be an imbalance of ecosystem. Birds will have to find new habitat to acquire their daily nutrient requirements. This may pose a problem since, there is no guarantee that the niche would be empty to accept birds. Other species may live there hence, food has to be shared and intrusion of privacy may occur. Some birds can tolerate these condition while others cant so you will find that the ones to adapt to this environment will survive (survival of the fittest) while the other will continue to roam if they find no satisfactoryly place their number will gradually decrease leading to extinction because there is no food to supply them. Now, if too many species inhabit the same habitat competition will lead to some species dying out and that habitat will be exploited over a short period of time. The cutting down of trees would leave the top soil vulnerable to leaching and erosion and void of any meaningful life. This would mean that birds who act as pollinating agent will not be able to do so anymore so land is left to become barren. Regrowth may take many years to occur. In well established habitat various species would create microhabitat in which they can carry out their person al activities such as breeding and reproduction. If no home is present birds cannot lay hence, their population will be reduced. They are also more exposed to predator since they will have no hiding space leaving more chances for them to become endangered. Birds in this state would have no social life since they would have to keep moving and get accustomed to new species, even if their used to be a benefit for their survival. The environment will also become unsuitable for mating since there will be no site for courtship because there will be a lack of provision of basic materials. In terms of nesting, materials will not be available to construct a comfortable nest for young to survive. When mother would go in search of food to feed them they will be more prone to predators since they will not be able to run away or defend themselves by flying high in trees because their is none and they would not be strong enough to give a warning call or produce a sound that would scare predator a way so they are being feasted upon. There will be no territory to mark since they lose all their living and feeding habitat. The land becomes dry and barren over time hence, tamper with the the nature and influence life forms in forested areas. Land becomes unproductive and serves no purpose. In the cases of natural deforestation it can be beneficial in some ways. It removes the vegetation cover but it also brings with it a rejuvenation of forest by adding other nutrients that can make the area favourable for a new group of species. It provides a variability of ecosystem over a period of time. Artificial deforestation change the whole balance of an ecosystem and birds lifestyle. It exhaust the soil and invade wildlife species. It weaken a forest resilience ability by exploitation of its resources and presistence. In Central Amazonia some species of galliform birds that disperses seed is being threatened due to hunting and habitat destruction (Mr. Borges). Because of deforestation there is need now for the conservation of these birds. Their reproduction is limited if they arent present in their natural environment. They tend to survive quite adequately in a regrown forest. In Southeast Asia there is quite a few numbers of threatened bird species (Thomas Brooks et al). this is due to the large scale deforestation done, which was suppose to held develop the countries. He thought only endemic bird would be prone to extinction. Based on the result he collected there was fluctuation between increased and decreased number of species. He concluded that deforestation affects species with small range and also bird species that will become extinct is very similar to the ones listed as threatened. In Australia a survey was done on quite similar bird species (Westphal et al) which showed that these birds adapted well to changes made in a few places in their inhabited forested area. They were able to live comfortably without making changes to their lifestyle. These birds are small and are very long distance flyers so they can adapt very easily. Based on the following investigation it can be concluded that some birds are vulnerable to complete habitat destruction. Some birds can withstand partial destruction of their habitat while some can adapt to the changing environment. This is due to the nature and structure of the birds as in how quickly they can do things for themselves i.e. some birds can fly and some cant and so on. If forested areas are gradually disappearing, some time in the future all birds are bound to be affected due to increasing predator-prey relationship, place to shelter and mostly because of a decline in food supply. To combat a situation like this policy makers are calling on leaders around the world to make a change. This can be done by sustainable forestry where parts of the forest removed is being replaced before it can be used again. In doing so, CO2 level will not increase in the atmosphere hence, more fresh oxygenated air will be available for bird to breathe in. Reforestation should also be carrie d out in areas than was completely exploited. This may take years so the future species will benefit if we start now since it is not a money consuming process. The little forest that remains should be conserved by using it wisely so that wildlife can be preserved and eco-forestry can be established. In other words by just having a forest pays, people actually pays to have a view of the various bird species worldwide. Legal wildlife trade can also be carried out to expand species richness. In addition to the decline of birds due to deforestation, it is not yet fully understood since much effects of this hasnt been stated clearly. A report carried out by (Duston et al) noted that in primitive times when deforestation was minimum bird species was still going extinct even before they became known to science but no reason was recorded for this. This must have been because the birds were hugh and clumsy hence, they were hunted to extinction. Most of them must have been flightless, competed for food and environmental conditions became unfavourable. Thus, modern birds evolve more efficiently for fast flight and increased activities.

Is Justified True Belief Really Knowledge? So, you think you found some truth in the traditional concepts that knowledge is true belief? Well, I just might have to burst your bubble and join up with Edmond L. Gettier’s famous counterexample’s to these particular beliefs. Gettier, published these ambitious counterexamples in a June 1963 article entitled, â€Å"Is Justified Knowledge True Belief.† The traditional concepts of knowledge seem to hold that the following three stipulations are jointly sufficient in verifying the claim that S knows p ( where S is some entity with the capacity for knowing and p is some proposition or claim): (i) p is true, (ii), S believes that p, and (iii), S is justified in believing that p. Gettier’s counterexamples demonstrate situations in which justified true belief does not lend to the yield of knowledge. Before stating his cases, Gettier is quick to note two points; The first being â€Å"it is possible for a person(S) to be justified in believing a proposition(p) that is in fact false.† And secondly, for any time S is justified in believing p, and p entails q which S then deduces from p and is then justified in believing q. This means that if a person(S) is justified in believing a false proposition, then they are justified in believing other false propositions or propositions that turn out to be true based on false propositions . Gettier, provides two cases, using two subjects(Smith and Jones), that are directly pertaining to two falicies inherent within the traditional beliefs of knowledge. In the first case, Gettier supposes that the two subjects(Smith and Jones) are both applying for a certain job and that Smith has strong evidence that Jones will get the job and that Jones also has ten coins in his pocket. This proposition could be verified if Smith was assured by the president of the company that Jones would get the job and also that Smith had recently counted the number of coins in Jones’ pocket. From this proposition you can then go on to deduct that â€Å"The man who will get the job has ten coins in his pocket.† Gettier then supposes that Smith sees this and is justified in believing so. Now here’s the contradiction, imagine that unknown to Smith, he is actually the one who will receive the job and that also unknown to Smith, he coincidentally also has ten coins in his pocket.

In the mind of Anselm he had noticed that there needs to be something that follows from all of this: if a being is perfect by definition, then that being must exist. Anselm believed that if a perfect being did not exist, then it would not be perfect. In which it would be impossible for God not to exist, for if He did not exist, there would be no definition of a perfect being. God is a â€Å"necessary being.† The example of you and I as perfect beings is not conceivable because we are not necessary beings, in our past if there were any change, then we would not exist. God is however different, He had to exist. This entire concept is known as the Ontological Argument. Though the Ontological Argument is very precise in being able to prove that there needs to be an existent perfect being to be able to have a perfect being. There are several flaws within this argument. For all of Anselm’s arguments to work, we would need a notion of content of his proposition that God is the highest human conception. We would also need a correlation between the conception of â€Å"being† in a general way of matching up to the idea of a â€Å"Supreme Being.† The problem that Anselm has is that there is not a â€Å"being† that matches up to the type of â€Å"being† that God is. If God were in existence, he would have to be in separable parts and divided into many places if he were to consist of being omnipresent. So He cannot be a perfect â€Å"one† being unless he was multiple beings of reality. What Anselm also didn’t cover was the fact of God being a Personal God. When Anselm came up with the line of reasoning known as the Ontological Argument. His argument provides no place or a need for the perfect being to be personal. Which is a big deal being a christian, believing in Inc... ...understanding. Which would mean that this person was greater than God. But nothing can be greater than God. Hence it is not true that God exists in the understanding but not in reality. In conclusion, the formulation of the argument from a metaphysical assumption and both philosophical and theological argument takes its false standpoint that builds up an entire edifice on assumptions that weren’t questioned back in Anselms’ day. Anselm then could not question whether â€Å"being† was continuous or discontinuous across cultures which philosophers developed much later. The argument is thus flawed insofar as it relies on a definition of the Supreme Being that is conditioned by human reason, while also assuming giving positive, univocal identification to created â€Å"being† and Supreme Being. Resting his theory in general on a divine exemplarism, which has not yet been proven.

What Is Compost? :: essays research papers

The process of recycling brush and leaves from curbside collection saves the city lots of money. When residents place their clean brush at the curb,they mustmake sure the pile is no bigger than six feet long and six inches in diameter.All leaves must be placed in clear plastic bags. Brush is collected separately from the leaves because the leaves are taken to the comppost drop-off facility for recycling. When a waste hauler driver comes to the drop -off facility loaded with brush,he or she must drive onto a scale so the load can be weighed.The driver information,load size and truck weights are then put into the computer for monitoring of driver,location,and weight. This policy helps the city find out which area of the city uses more collection or which area of town was affected more by a storm. THe driver will drive out to the disposal site and bump the brush in a pile.THe piles of brush are then compacted and pushed up until there is no available room on the site. Roughly every three months,the city contracts a grinding company to come out and grind all of the brush on the site.It generally takes the grinding company three weeks to grind all of the material After the grinding stage,the material is screened by using trammel with 3/8 inch screens.The materials are placed into windrows,this process speeds up the decomposition process.The small particles are then separated from the larger first grinds. The small material now becomes a product known as mulch fines. Once the first grinds have been screened, they will be reground using a tub grinder. The reground material is known as reground mulch. The reground material is not treated with any chemicals.It is allowed to cure or sit for 48 to 72 hours after being processed. The much product heats up naturally to temperatures from 140 to180 degrees.The temperture of the leaves is monitored and moisture is added when the leaves start becoming dry.When the leaves start to decompose the temperature can rise up to 200 degrees.After the decomposition process has taken place,the temperature decreaces to about 120 degrees. This natural process eliminates bugs and thier eggs.All trash and plastic bags are taken out of the material and it is now ready to be recycled and sold for public use.

Critical Approaches to Literature Should Not be Required of English Majors :: Argumentative Persuasive Argument Essays

Critical Approaches to Literature Should Not be Required of English Majors In the controversy that surrounds the issue of requiring English majors to take Critical Approaches to Literature, it is not important whether the course is academically justifiable, but whether requiring English majors to take it is justifiable. By thinking about this issue in this way, I have concluded that Critical Approaches to Literature should not be required of English majors. The main reason for including Critical Approaches to Literature as a required course for English majors is to incorporate a sense of multi-culturalism and feminism into the English major. I would be the first to agree that writers such as Toni Morrison, Langston Hughes, Beth Bryant, and Sherman Alexie should be required reading for all English majors at some point in their education because these authors and their works do bring a dimension of multi-cultural appreciation and feminist understanding to the student's literary background. However, the Critical Approaches to Literature class that I attended did not teach me to appreciate the literature of other cultures; instead, it taught me how to analyze Western Literature as if I were a sociologist or psychologist. In this class, I began to feel that there was a hidden agenda imbedded within the course's objectives. This agenda was to destroy the literature, which I am familiar with, of the culture I have grown up in, and to force me to appreciate the literature of other cultures along the way. It did not work. By saying, "It did not work," I do not mean that I have no appreciation for the literature of cultures other than my own. What I do mean is that if I had not already possessed an appreciation for Multi-cultural and Women's Literature, Critical Approaches to Literature would not have conveyed this appreciation to me. I firmly believe that the poetry of Maurice Kenny is some of the most powerful poetry that I have ever read, and Duan Niatum's love-poem "Round Dance" is comparable to the best poetry that Western Literature has to offer. These are authors I know and love not because I have taken Critical Approaches to Literature, but because I have read these authors' works in a Native American Literature course. This is one reason why Critical Approaches to Literature should not be

Media Convergence Worksheet Essay

Questions Answers What is meant by the term media convergence with regard to technology, and how has it affected everyday life? Since I have been going to school I had never heard of the word â€Å"convergence† I first learned about this when I enrolled in my Humanity 176 course. Convergence by definition is the exchange of various digital media such as music, radios, pictures. Convergence used in a technical sense is the exchange and sharing of digital media through computers and other mobile devices. Over the years Media has expanded and excelled across the world to bring the people all sorts of media attention and the ability to be able to converge onto there devices allows an assortment of options such as Internet TV whether it is free or on demand, voice telephone options such as Skype and other simple internet services which include Facebook and Windows Live Messenger. †¦ I believe that our technology has an extreme affect on everyday life, most of us would not know how to function without it, including myself. What is meant by the term media convergence with regard to business, and how has it affected everyday life? Media convergence gives businesses an opportunity to share information regarding any topic within and to others outside of the business like costumers with easy methods. This is really appropriate to meet consumer’s desires for instant and easily practicable and easy to acquire any information from any business. Media convergence regarding to business is used to offer media more professionally or efficiently and in an on demand way. In other words media convergence brings the opportunity to provide information to be acquired when a customer wants to and regarding any topic. Media convergence’s cons embrace less serviceable performance or fewer personnel to reach more people daily. Some elements are acquired from medi a devices or procedures in order to add on stipulate material. Thanks to  today’s technology, people can receive information regarding any services provided by any business or company. Through sources like the internet, customers can browse and purchase products through websites and other business providers. With this technology it makes it very easy for the customers to be able to find many different products for fair prices on what the business needs. Of course, business convergence also deals with far more than buying and selling from a store front. People are also able to set up their business through their own home via the internet. Business goes hand in hand with technology also, as they are able to advertise through television, radio and internet sites with their ads and commercials. Business convergence has become a big source in today’s media, and will continue to grow with technology as they work together to provide people with better and easier ways to conduct business. What are some of the issues that result from depe ndency on modern media? Describe at least three issues. They are things like ethical Issues. We depend on the media to tell us that what we are doing is wrong while we still do what we know is wrong. More and more people who depend on media and need the media is that much closer to being constantly influenced by the media. Our society depends on media and without it we would fall apart. We tend to believe what the media says instead of formulating our own thoughts.With the media the way it is we tend to accept this as part of our lifestyle without question The public also has an insatiable curiosity to know everything, except what the world is really trying to tell us. Another topic of discussion is drugs. Everyday you see ads and commercials and people talking about not doing drugs and we depend on this to teach are kids but in reality we need to learn to teach our kids morals instead of constantly relying on the media.. Commercials that promote alcohol and drinking are abundant on television. While other media shows people doing drugs a nd getting money from the sale of them. The media also tends to butt heads between other countries due to mis-information that was released over the media sites. Terroism comes in all forms when it comes to the internet. Some examples are identity theft, hacking into databases, creation of viruses and other deliberate means to destroy or harm personal objectives are all forms of cyber-terrorism. People seem to have an addiction to technology and cling to it as the world would end without it. Dependency of modern media has taken over and does not allow society to  function thoroughly as it should. The issues it brings with it outweighs the benefits because it’s mostly used in negative ways instead for good. How does media literacy help with responsible media consumption? The literacy of the Media is out there to challenge people with the understanding the representation of the media, with how it influences our culture. Media is out there to give the students the ability to read and write and be more competitive in our media culture. It uses an inquiry-based instructional mold that encourages people to ask questions about what they watch, see and read. Media literacy can also aim to enable people to be skillful creators and producers of media messages, both to facilitate an understanding as to the strengths and limitations of each medium, as well as to create independent media. †¦ By transforming the process of media consumption into an active and critical process, people gain greater awareness of the potential for misrepresentation and manipulation (especially through commercials and public relations techniques), and understand the role of mass media and participatory media in constructing views of reality. †¦ Protectionist approaches to media literacy emphasize the need to be aware of the negative aspects of mass media and popular culture, including the dangers and risks of online social media.

Sociology: Ethnicity and Crime

Using material from Item B and elsewhere, assess explanations for apparent ethnic differences in involvement in crime (21 Marks) According to official statistics, ethnic minorities are largely linked to crime and their involvement if often over exaggerated. Item B shows that black people make up 11% of the prison population, despite the fact they make up just 2. 8% of the population. Whilst, Asians make up 4. 7% of the population yet 6% of the prison population.These statistics emphasise that ethnic minorities are over-represented in the criminal justice system, and so the use of alternate sources of statistics may help show a more accurate picture. Victim surveys ask individuals what crimes they have been victims of and help identify the correlation between ethnicity and offending. They tend to show a great deal of intra- ethnic crime but also include several limitations as they rely on victims memory of events which could result in over- identifying certain ethnic groups as the off ender.Whereas, self- report studies ask individuals to disclose their own dishonest and violent behaviour. The findings of self- report studies challenge the stereotypes of black people as being more likely than whites to offend. However, self-report studies also have their own limitations as inconsistency is shown through the evidence of ethnicity and offending. There are ethnic differences at each stage of the criminal justice process. Policing is often seen to be oppressive, as members of ethnic minorities are more likely to be stopped and searched with Asians being twice more likely than blacks to be stopped by the police. Feature Article –  Sociology TestThese allegations have meant ethnic minorities have limited faith in the police and therefore feel under protected. Police racism is one of the many causes behind stop and searches with the MacPherson report identifying institutional racism within the police force. These types of racist behaviour and stereotypes are endorsed and upheld by the â€Å"canteen culture† of rank and file officers and lead to deliberate targeting of stop and searches. In 2007, just over a quarter of the male prison population were from minority ethnic groups.As such, blacks were five times more likely to be in prison than whites while blacks and Asian offenders are more likely than whites to serve longer prison sentences. This is because ethnic minorities are less likely to be granted bail while awaiting trial. The official statistics on the criminal justice process shows striking differences between ethnic groups, and these patterns have been examined by lef t realists and neo- Marxists. Left realists, Lea and Young focus on the statistics which represent real differences in rates of offending by different ethnic groups.They argue that crime is the product of relative deprivation, subculture and marginalisation whereby racism has led to the marginalisation and economic exclusion of ethnic minorities, who face a higher level of poverty and unemployment etc. In contribution to this, the media’s emphasis on consumerism promotes relative deprivation amongst ethnic groups, who are unable to attain these materialistic goods by legitimate means. This results into the formation of delinquent subcultures, most notable amongst unemployed black males.Utilitarian crimes are most likely to come of this, such as theft and robbery as a means of coping with relative deprivation. As these groups are likely to be marginalised, it means they are also likely to express their frustrations through non-utilitarian crime such as violence or rioting- thi s explains the involvement with crime by ethnic groups. Lea and Young acknowledge that the police may act in unjust ways but they don’t believe that discriminatory policing fully explains the differences in the statistics.Evidence to support this is that 90% of crime is reported to the police by the public rather than discovered by the police themselves. Lea and Young conclude their argument that the statistics represent real differences in levels of offending between ethnic groups, and that these are caused by real differences in levels of relative deprivation and marginalisation. Despite this, Lea and Young are criticised on several grounds that arrest rates for Asians may be lower than that of Blacks yet this isn’t because they are less likely to offend but because police stereotype the two differently.On the other hand, neo- Marxism tends to view statistics as a social construct resulting from racist labelling and discrimination in the criminal justice system. Item B brings to light Gilroy’s argument over the myth of black criminality that â€Å"black criminality is a myth created by racist stereotypes of African Caribbean’s. In reality, this group is no more criminal than any other. However, as a result of the police and criminal justice system acting on these racist stereotypes, ethnic minorities come to be criminalized and therefore appear in greater numbers in the official statistics†.The item helps us understand the extent of stereotypes and its effects on ethnic groups, yet Gilroy furthers his argument by identifying working class crime is a political act of resistance to capitalism and a racist society. Lea and Young refute Gilroy’s argument, by suggesting that most crime is intra- ethnic, so it can’t be seen as an anti-colonial struggle against racism. Lea and Young also criticise Gilroy for romanticizing street crime as somehow revolutionary, when it’s nothing of the sort.Moreover, Stuart Hal l et al also adopts a neo- Marxist perspective and found that the 1970’s saw a moral panic over black â€Å"muggers† that served the interests of capitalism. As unemployment and strikes were increasing, the ruling class needed to use force to maintain social control. In their view, the emergence of the black mugger and the capitalist crisis was no coincidence, as the black mugger was used a scapegoat to distract attention from true causes of problems such as unemployment. By presenting black youth as a threat to society, the moral panic began dividing the working class on racial grounds.However, Hall et al doesn’t argue that black crime was solely a product of media and police labelling. The crisis of capitalism was increasingly marginalising black youth through unemployment which resulted them into committing petty crime as a means of survival. Hall et al’s study of policing the crisis was criticised for not presenting how the capitalist crisis led to a moral panic, nor do they provide evidence that the public were blaming crime on blacks. During recent years, the focus of ethnicity and crime has largely been on the over representation of black people in the criminal justice system.However, more recently there has been shift in other issues such as the racist victimisation of ethnic minorities. Racist victimisation was brought into greater public focus with the racist murder of Stephen Lawrence and the police handling of the case, where most information is brought to life by victim surveys such as the British Crime Survey. The British Crime Survey found that most crimes go unreported and found that the risk of being a victim varies by ethnic group, whereby statistics showed that people from mixed ethnic backgrounds had a higher risk (36%) of becoming a victim of rime than blacks, Asians and whites faced. While the statistics recorded the instances of victimisation, they do not necessarily capture the victims’ experience of i t. Sampson and Phillips note, racist victimisation tends to be on going over time, with repeated minor instances of abuse and harassment interwoven with incidents of physical violence. This has led minority ethnic communities becoming more active in responding to victimisation, with situational crime prevention measures to organised self- defence campaigns taking place.Such responses need to be understood in the context of accusations of under- protection by the police, who fail to record or investigate reported incidents properly. The Macpherson enquiry into the Stephen Lawrence case concluded that the police investigation into death of the black teenager was â€Å"marred by a combination of professional incompetence, institutional racism and a failure of leadership by senior officers†. Ultimately, we have learnt the differences in ethnicity and crime but have established ethnic minorities also becoming subjected to victimisation.
