A Light Emitting Diode Engineering Essay

A Light Emitting Diode Engineering EssayA Light-Emitting Diode in core group is a P-N junction solid-state semiconductor diode that emits comfortable when a authentic is applied though the turn of events.1 By scientific definition, it is a solid-state device that controls underway without the deficiency of having heated filaments. How does a lead work? White leads ordinarily need 3.6 Volts of Direct Current (DC) and expenditure virtually 30 milliamps (mA) of current and has a power dissipation of approximately 100 milliwatts (mW). The positive power is connected to one side of the guide semiconductor through the anode and a hairsbreadth and the other side of the semiconductor is attached to the top of the anvil or the shun power lead (cathode). It is the chemical composition or shamup of the LED semiconductor that determines the color of the trip that the LED catchs as well as the intensity level. The epoxy resin enclosure allows most of the unwarranted to escape from the elements and protects the LED making it virtually indestructible. Furthermore, a light-emitting diode does not have any moving parts, which makes the device extremely resistant to damage due to vibration and shocks. These characteristics make it ideal for purposes that demand reliability and strength. LEDs therefore can be deemed invulnerable to catastrophic failure when operated within design parameters.Figure 1 shows a regular(prenominal) traditional indicator LED. Traditional indicator LEDs utilize a small LED semiconductor run that is mounted on a reflector form also known as the anvil, on a lead-frame (whisker).This whole configuration is encased in epoxy which also serves the purpose of a lens. LEDs have precise high thermal resistance with up of 200K per Watt.LEDs atomic number 18 highly monochromatic, only emitting a single pure color in a narrow oftenness range. The color emitted from an LED is identified by peak curllength (lpk) which is measu expiration in nano meters (nm). The peak wavelength is a function of the material that is use in the manufacturing of the semiconductor.3 Most LEDs are produced using gallium-based crystals that differ in one or more additional materials much(prenominal) as phosphorous to produce distinct color. Different LED chip technologies enable manufacturers to produce LEDs that emit light in a special(prenominal) region of the palpable light spectrum and replicate different intensity levels. Thus, one would exchange the material utilise in the production of LEDs in order to obtain the desired results. The graph below depicts the variation in response time for the specific wavelength of light.Principle MechanismThe essential portion of the Light Emitting Diode is the semiconductor chip.Semiconductors can be either intrinsic or extrinsic. Intrinsic semiconductors are those in which the electrical behavior is based on the electronic structure inherent to the pure material.5 When the electrical characteristi cs are dictated by impurity atoms, the semiconductor is tell to be extrinsic.6 obtain Appendix A for further information regarding the different materials and their characteristics. This chip is further divided into two parts or regions which are detached by a boundary called a junction. The p-region is dominated by positive electric charges (holes) and the n-region is dominated by negative electric charges (electrons). The junction serves as a barrier to the flow of the electrons between the p and the n-regions. This is somewhat similar to the role of the band-gap because it determines how much voltage is needed to be applied to the semiconductor chip before the current can flow and the electrons pass the junction into the p-region.In general, to achieve higher momentum states (with higher velocities), there must be an empty ability state into which the electron may be excited. (In other words, to achieve a net flow of electrons in one direction, some electrons must change the ir wave vectors thereby increasing their energy.) 8 Band-gaps determine how much energy is needed for the electron to jump from the valence band to the conduction band. As an electron in the conduction band recombines with a hole in the valence band, the electron makes a transition to a lower-lying energy state and releases energy in an amount play off to the band-gap energy.This energy is released in photons. Normally the energy heats the material. In an LED this energy goes into emitted infrared or visible light.If a large lavish electric akinly difference (voltage) is absent, across the anode and cathode, the junction serves as an electric potential barrier to the flow of electrons. When sufficient voltage is applied across the chip of the LED, the electron has enough driving force to move in one direction over the junction that separates the p-region and the n-region. The p-region (holes) is where the positive charge forms the majority of charges. (Implicitly, there are als o negative charges but they are the minority).Vice versa for the n-region. The electrons from the n-region basically flow across the junction into the p-region. In the p-region, the electrons are attracted to the positive charges due the mutual Columbic forces of attraction between opposite charges of alike magnitude. Thus recombination occurs.After every successful recombination, electric potential energy is transformed into electromagnetic energy. This releases a quantum electromagnetic energy that is emitted in the form of a photon of light with frequencies characteristic of the semiconductor that was utilize in the process. These photons have specific wavelengths thus specific alter according to the different materials apply. Therefore, different compositions of the chemical elements used in the manufacturing of the semiconductor results in different color emitted as well as different energies needed to light them.The electrical energy is in relation to the voltage comman dd to enable the electrons to flow across the p-n junction. Predominantly, LEDs emit light of a single color.ApplicationThere are various materials that are used in the manufacturing of Light Emitting Diodes. Most of the materials are gallium-based crystals and are used in high-brightness applications. Gallium is a minor metal noted by its low warming point of 29.8 C, the name being derived from Gallia, the Latin for France, which was where it was discovered. 14Among these include AlGaAs (Aluminum-Gallium-Arsenide), a semiconductor that typically generates the red spectrum, often used in signs, displays and electronic equipment.InGaAlP(Indium-Gallium-Aluminum-Phosphide) produces the yellow-green wavelength tored are often used in signs, auto interior as well as exterior, traffic signals and cellphones.15 InGaN (Indium-Gallium-Nitride) typically generates Blue, Green and white spectrums and are used most often in full color signs, cell-phones, auto interior, trafficsignals.16. Furth ermore, there is room for further improvement on the design of traffic lights. The visible light from the LEDs in a traffic light can further be modulated and encoded with information. Hence, it can be used for the broadcasting of audio messages or any traffic or road information. Essentially, all LED traffic lights can be used as communications devices. 17 InGaN LEDs overly has been made the light source of choice for many diagnostic and photo-therapy applications from the Ultra-violet to the near Infrared. 18 Light-emitting diodes (LED) emit light in proportion to the forward current through the diode.Light Emitting Diodes are the penetrative edge technology of lighting today. Generally,Light Emitting Diodes are categorized according to their performance. The performance of aLED is linked to a few primary characteristics of the LED itself which includes color, peak wavelength and intensity. As LEDs are highly monochromatic, LEDs are differentiated according to their peak wavelen gth. Peak wavelength is a function of the LED chip material.Although manufacturing process variations produce a standard deviation of 10nm, nevertheless, these variations are perceptible to the human eye because the 565nm to 600nm wavelength spectral region (yellow to amber) is where the sensitivity level of the human eye is at its peak. 19 See Appendix B for details on the different semiconductor oddballs as well as characteristics of those semiconductors.The light output of a specific LED varies with the type of chip, encapsulation and efficiency of individual wafer lots. There may be other random variable stars that may affect the performance of the LED too. This typically is categorized into the nuisance variable factor and is taken into account as the error margin. Many LED manufacturers use different terms such as super-bright, and ultra-bright to describe LED intensity. However, such terminology is entirely subjective, as there really is no industry standard for LED brightne ss.Luminous intensity is roughly proportional to the amount of current (I) supplied to the LED. The greater the current, the higher the intensity.20 Nevertheless, luminous intensity (Iv) does not represent the natural light output from an LED. Both the luminous intensity and the spatial radiation physique (viewing angle) must be taken into account. If two LEDs have the same luminous intensity value, the lamp with the larger viewing angle will have the higher total light output.Overall visibility can be enhanced by increasing the number of LED chips in the encapsulation, increasing the number of individual LEDs, as well as utilizing secondary optics to distribute light. To illustrate, consider similar red GaAlAs LED chip technology in four different configurationsIn all(prenominal) individual case, the amount of visible light depends on the application of the LED as well as how the LED is being viewed. The single chip frame-up may be suitable for direct viewing in contrast with hi gh ambient lighting. The 6-chip may be more suitable as a backlight to a switch or small legend, while the cluster or lensed LED design may best be used to illuminate a pilot light or larger lens.In this millennium, Light Emitting Diodes or LEDs are making major inroads into a lot of industries. In the past, filament bulbs like incandescent and halogen lamps dominated and were the main source of lighting. Today, in the automotive industry, we see cars with LEDs for taillights and instrument panels. Why the switch to the new technology? Among the reasons why include the higher status of the LED itself. It lasts on average 20,000 hours for a 15-Watt traffic light in comparison to 1000 hours for typical filament bulbs.23 Generally, LEDs are designed to operate upwards of 100,000 hours. This greatly supercedes the standard incandescent bulb with an average lifespan of about 5000 hours.LEDs too are low voltage devices that respond almost instantaneously to changes in current (10Mhz).24T his would entail better safety for motorists on the road. Costs of maintenance of the vehicle would too decrease as replacements of the lighting fixtures need not be done as often. With such fast reponse times, LEDs used as an unbiased photodiode, exhibits a non-linear power dependent response that also can be used for sensitive detection and characterization of mode-locked femtosecond and picosecond laser pulses. 25In the electronic industry, we have LEDs for lighting of almost everything. The ergonomic flat-panel computer screens otherwise known as lucid crystal displays (LCDs) are also in essence miniature LED clusters. The introduction of LCDs marks another milestone in development in the hi-tech industry. Displays now can be made that use less power as well as emit much less radiation in comparison with the traditional cathode ray tube(CRT) display. According to Keith Robinson for Frost Sullivan, The light emitting diode(LED) market, especially the visible LED (VLED) market, is poised to experience explosive maturation once economic conditions improve in North America. The most significant technology improvement that has taken place in the last 10 eld for LEDs is the introduction of blue and blue-green LEDs. The nitride-based LEDs have opened new opportunities for manufacturers of lighting products, such as traffic signal manufacturers and outdoor signboard manufacturers. The increased use of the new colors in consumer products and automotive applications is expected to have a positive impact on the market. 26Manufacturers have always been striving to replicate colors as accurately as possible.This is has always been the holy grail for the display industry. LEDs have made this a reality. Typical incandescent bulbs cannot replicate the vivid colors that can be reproduced using LEDs. LEDs give pure saturated colors with up to 130% more gamut compared to standard NTSC specifications.27 Take the reproduction of white light. When light from all parts of th e visible spectrum overlap one another, the additive mixture of colors appears white. However, the eye does not require a mixture of all the colors of the spectrum to perceive white light. Primary colors from the upper, middle, and lower parts of the spectrum (red, green, and blue), when combined, appear white. To achieve this combination with LEDs requires a sophisticated electro-optical design to control the blend and dispersal of colors. Variations in LED color and intensity further complicate this process.Presently, it is possible to produce white light with a single LED using a phosphor layer (Yttrium Aluminum Garnet) on the surface of a blue (Gallium Nitride) chip.28Although this technology produces various hues, white LEDs may be appropriate to illuminate opaque lenses or backlight legends. However, using colored LEDs to illuminate similarly colored lenses produces better visibility and overall appearance in comparison with CRTs. Moreover, LEDs are not deficient in the relia bility department. LEDs are solid state devices with no moving parts as well as no fragile glass or filaments.LEDs too use up to 90% less energy in comparison with conventional bulbs and lamps today.29 Today a LED flashlight may last up to 200% agelong with the same batteries used to operate conventional filament flashlights. 30 Furthermore, LEDs are environmental friendly because they contain no mercury and since they last longer (about 100,000 continuous hours of life) there will be less disposal waste in the environment. This in turn would result is less pollution and less wastage of our curious and limited resources.LEDs also form the foundation for applications in optical-fiber communication and diode lasers. They produce a narrow spectrum of coherent red or infrared light that can be well collimated. This characteristic of the light produced by LEDs has enabled engineers to manipulate the setup to enable info transfer. This has made it possible for continents to be linked v ia the internet. selective information can be sent across the globe in a matter of fractions of a second and vast chunks of data can be hereditary without a hitch. With the improvement of infrastructure, the benefits extend also to the general populace. Before we had modems that used coaxial copper cables, today we have T1 to T3 connections which utilize fiber optics.Most institutions, organizations and companies that require the use of large bandwidths of data have such connections. Take for example, San Jose State University, it utilizes severalT3 connections to the internet and has T1 connections locally across campus to alleviate data congestion. In this way, data is made readily available to those hungry for knowledge.ConclusionLight Emitting Diodes has such a profound impact on society. It affects our daily lives as well as activities. It is used in so many applications and so many places. With LightEmitting Diodes, so many significant improvements to already existing techno logy could be made. historically the LED market has experienced signal digit growth of about 8.5 percent.The laser diode market has experienced double-digit growth in the past of approximately30.0 percent and once economic conditions improve it is anticipated that the market will experience strong growth rates once again. 31 As this technology expands, so does our horizon and our conquest for the betterment of todays technology. Light Emitting Diodes truly is a great invention of the age.

Effects of Austerity Measures on Communities

Effects of Austerity Measures on CommunitiesSocio-economic and political factors identified in the company of Croydon and the links to key concepts and theories from sociology and sociable policy.IntroductionThis raise snapes on the socio-economic and political factors identified in the union of Croydon. It sets fall out to explain how these factors link with key concepts and theories from sociology and friendly policy and how this impacts on the community. The main focus here is on the factors that set out exacerbated the issues faced by the community. affable detonator will form the base for intimately of the arguments and points.The Cambridge Academic Content Dictionary (2008) watchs socio-economic as related to the differences mingled with groups of commonwealth caused by, primarily their financial situation. It crapper hence be argued that these atomic number 18 factors and experiences that form and define these groups of people and also these ar the factors tha t decide whether these groups be condemned to a life of poverty or non.The union Croydon (see definition of a community above)Croydon, with a people of three hundred and eighty two thousand (382k) people (www.london.gov.uk) has the second epicst population of all the London Boroughs. It also has the largest number of people aged beneath fifteen numbering 84k. jibe to Councillor Tony Newman, also the Chair of the Local Strategic Partnership, Croydon is chthoniangoing transformation to become a modern European city and behind do divulge without bad publicity such as poke crime. It is a diverse community with a diverse ethnicity, faiths, sexual orientation and schoolman standing all go bading in different jobs to serve various needs of the community.Knife abuse A bane for the topical anesthetic communityThe Community of Croydon has been named one of the worst five amongst London Boroughs for knife crime across London. The community is facing unprecedented levels of knife crime which is attributed to budgetary cuts to attend tos that rear social capital to issue people and another(prenominal) services such as policing. When the people who police and monitor crime say so, it is difficult to make out the issue. The Association of legal philosophy and Crime Commissioners argues that with reductions in staff levels and support services already made, further budget constraints will lead to difficult questions on how best(p) to structure police forces to respond to changes in crime, and what this would mean for the local service provided to the public. In the month of February 2017 alone, the Mayors Office for Policing and Crime (MOPAC) reported 94 knife injuries pull inted by jejuners under the age of 15. While the Home Office has no precise definition of knife crime, however knife enabled crime includes a compartmentalization of other offences involving a bladed weapon, for example it is an offence to cause or threaten harm with a knife and if used in a robbery or assault, it aggravates the offence.How the Council Gets Its Information on Knife CrimeBut before delving deeper into this issue, it is very consequential to put into perspective how the community of Croydon and local authority converge information on this bane of knife crime and also give a backdrop to the motivating factors that influence the compilation of this information.In 2008 a teenage boy named Shakilus Townsend was stabbed several periods by other teenagers in Thornton Heath, a district of Croydon. This culminated in the council instituting an investigation named Scrutiny on Knife Crime to focus on teenagers, perpetrators and victims alike. (Available at Croydon.gov.uk)The Croydon council gathers and obtains information about knife crime through public meetings held with the UK Youth Parliament, vulnerable young people, Metropolitan Police Authority, the Croydon Youth Crime Pr even offtion Strategy and other stakeholders. Meetings are also held wit h secondary schools, Pupil Referral Units, Head T individuallyers and the British Broadcasting Corporation.Social CapitalSocial Capital has many another(prenominal) definitions, but to put into social work context, the simplest definitions that fit in well with social work are used here. Coleman (1990) argues that social capital is defined by its function as it is not a single entity, but a variety of different entities having two characteristics in common They all consist of nigh aspect of social structure, and they facilitate certain actions of individuals who are within the structure. However, Brehm and Rahn (1997, p. 999) put it in another way arguing that social capital is the web of conjunctive relationships between citizens that facilitate resolution of collective action problems. It can therefore be argued that social capital has an economical value in it and that this value increases the belligerent advantage of individuals through networking through organisations like the local authority provided facilities.The World Bank defines social capital as institutions, relationships, and norms that shape the quality and quantity of a societys social interactions. The World Bank goes on to elaborate by stating that social cohesion is critical for societies to prosper economically and for festering to be sustainable. Social capital is not salutary the sum of the institutions which underpin a society it is the glue that holds them together. While knife crime is one of the major social problems facing this community, this essay seeks to highlight why budgetary cuts, which are a consequence of social capital deprivation, are an indirect consequence of the knife crime coupled with other social issuesThe Poisoned Chalice of Neo- freehandedismAs social capital has already been defined above, it is important to put it into perspective so that there is an understanding that the reduction in services that provide social capital for the young has come about as a matter of neo-liberalism, so there is a link between The Liberal Democrats whose ideological tradition is liberalism, an ideology that favours privatisation, and the contraction of the public sector/services, reinforced by its ideology of neo liberalism on the coat tails of a book titled the Orange Book Reclaiming Liberalism. Thomson and Thomson (2008) argue that politics plays a fundamentally important role in shaping social work and therefore it could be argued that it is important to buttress several(prenominal) points with an understanding of the role therefore political soures play in social work. Now back to the Liberal Democrats. break off Clegg later became leader and he would later use his presence and influence in the Coalition to oversee the shutting down of some received Starts childrens centres and Connexions in the name of economic liberalism. This policy also oversaw the privatisation of job seeking being contracted to a private individual operating as if it was under the auspices of the Department of Works and Pension (DWP) using a website under the name Universal Jobmatch where thousands of fake jobs were advertised by a private asseverator who was paid for roles which should use up been performed by the DWP. Incredibly the scandal which left jobseekers at the mercy of this government approved scam, fizzled out without much fanfare. A lot of jobseekers who were already being deprived of services such as the Connexions had to face the frustration of applying for nonexistent jobs.To put it into context, Connexions was a support service for young people, a service that was meant to help them with advice on topics including education, housing, health, relationships, drugs, and finance. Now these are young people who were most in need. An argument may be developed that says these young people, through a policy of neo-liberalism are likely to develop personal problems and that these personal problems will overlap into a societal problem. The se are the apparent knock on effects. policy-making Austerity, a function of neo-liberalism affecting social capitalBattle and Lewis argue that a persons education is closely linked to their life chances, income and well being. When the Conservative and Liberal coalition government came into military group, they made tackling our record debts, as they called it then, one of their cornerstones in dealing with debt. The Liberal Democrats are well remembered by most students for reneging on a policy to scrap university fees altogether. Not only did they renege on this policy, but they went on and signed up to an agreement to actually allow institutions to charge fees up to nine thousand pounds. Now a prospective student from a deprived background would be call for seen the prospect of finishing university with a debt of over xxx thousand pounds not such an attractive prospect.The Croydon Guardian newspaper interviewed 4 teenagers aged 16 to 18 to try and get to the bottom of the sco urge of knife crime in their community. One of the teenagers had this to say Adults should give children more job opportunities and training. This will attract other teenagers too. We need to ask what they like doing so they have the chance to do what they want. I was part of a gang, but for what? Sometimes there is no explanation. Unquote. The other three teenagers also had more or slight the very(prenominal) to say.Another major point of concern that came out of the interviews was that young people carry knifes as a form of defence due to the large numbers of gangs dominating the community. They smack they have to protect themselves. Mills (1959) links what happens to an individuals life with social structures of the wider world. Mills states that the private troubles of men/women effectively trapped them in their lives as they understood only their immediate personal difficulties rather than understanding what was happening to them particularly in reference to historic and hi stories of their surroundings. These young men and women bump trapped. It can therefore be argued that if it were not for cuts that affect the number of police in the streets, these teenagers would not feel the need to carry knifes as the police would be there to protect them.Unfortunately this policy of austerity does not affect teenagers only. Some Sure Starts were at the receiving end of these cuts as real spending fell, so states the Nuffield report. To put it into context again there is a need to understand the core purpose of Sure Starts. They were actually developed in consultation with the child sustainment Act 2006 and therefore it could be argued that their closure indirectly impinges on the development of children. Their core purpose, as the government states, is to make available universal and targeted early puerility services either by providing the services at the centre itself or by providing advice and assistance to parents, mothers and fathers, and prospective par ents in accessing services provided elsewhere. Local authorities must(prenominal) ensure that childrens centres provide some activities for young children on site. What can be argued here is that a child who was nine in 2010 when the coalition government took power is now a teenager and poorer in terms of education and social capital due to the austerity which affected the number of these centres made available. The knock on effect is that this rack is being repeated. If society is going to deprive young people of socialisation at an early age surely what can be expected of the this generation in terms of what they contribute to the well being of a community and the society at large? Cunningham and Cunningham (2009) observe that troubles of individuals are inherently personal and unique however they happen as a result of specific set of socio-economic and political circumstances.Again the Nuffield report, already mentioned above, goes on to state that the issues that are the princ ipal concern of its inquiry are social outcomes, poverty and inequality and argue that the Coalition had inherited a better situation than its predecessor apprehend whose social programmes had delivered expanded public services. Socio-economic gaps in access to services had decreased. Economic and social outcomes, such as pupil achievements and child poverty, had also generally not improved, while differences between the most and least deprived social groups narrowed, the report goes on to state.The Deprivation of Social CapitalIt can be argued, taking in all the information above, that the exercise of shutting down some Sure Starts and Connexions branches deprived teenagers and other young adults opportunities that could have prepared them better industry leading of tomorrow. It deprived them of opportunities to socialise and share ideas with like minded peers.The legislations attempt to stop people from carrying knives has not been that successful due to the fact that knife crim e is however prevalent in Croydon. Government has imposed penalties of up to 4 years maximum for carrying a knife however this legislation is evidently not a deterrent as knife crime is still prevalent in that community. The law allows for pressure groups to work in collaboration with the society and the police in tackling the crime. However according to Hill and Irving (2009) choices of what pressure groups can work on are dictated by local interests. One can see how the flunk of an individual voter is strengthened through belonging to an influential group. Hill and Irving go on to argue that direct interventions in elections motivated by local issues are rare. This essentially means come election time the issues that really matter to the community are put in the back burner hence the cycle of these social problems still persist unabated.Charities and the METCampaigns such as No Knifes Better Lives look at the individual, putting pressure on the family to change with very micro change in the role of the state in improving the economic circumstances of the victims. The No Knifes Better Lives approachs challenge is that it focuses on the implement used to commit the crime ignoring the causes or underlying socio economic circumstances. One can argue that if their campaign was focused on getting rid of poverty, access to equal opportunities and education, in the long run this might reduce knife crime.Another organisation helping young people refrain from using knife is the Turnaround centre. This is a place where young people can drop in and ask for advice and support. Incredibly these organisations rely on the magnanimity of well wishers for funding which actually limits their backcloth of how much they can do.According to the census figures, Croydon has one of the largest Afro/Caribbean populations. This makes it very difficult for the police to enforce the Stop and Search due to the McPherson reports branding of the Metropolitan Police (MET) being institut ionally racist, something the MET actually admitted. To compound that, when the practice was in use it disproportionately targeted Black males. So this dilemma has made the police lose out on an otherwise valuable crime fighting tool.The police are currently working together with many stakeholders in addressing problems in the community. In the same breath they should have a social worker working with them and becoming an acceptable face of the solution to the community.One can argue that social workers are always at arms length dealing with issues, rather should be on the frontline instead of being reactive in dealing with societal issues.According to the Health and Care Professions Councils (HCPC) standards of proficiency (SoP), social workers must be able to recognise and respond appropriately to unexpected situations and manage uncertainty. It could be argued that this might just be possible in an idealistic world but not in a profession that faces so much austerity cuts. Social workers, by the nature of their profession, have the unique advantage of seeing and understanding how poverty and discrimination affect lives and thereby communities. So it is a big ask for them to sham a balance between meeting SoP and at the same time lawfully practice. It is therefore imperative that social work should be a protected profession, protected from cuts forever. The social work profession, according to the International Federation of Social Workers, expects the practitioners to promote social change, help to foster world relationships and in the process liberate people through empowerment. Again it becomes very difficult, one may argue, that you can operate in an environment that prioritises money above the welfare of human beings.RecommendationsThe Croydon council has recommended the continuous review of developing a range of services for all young people in Croydon. Specifically, investment in expanded opening hours for places where young people can be into the l ate afternoon and late at night during summer months should be explored and future opportunities for younger children actively considered.Another important recommendation was that the local authority should give consideration to the creation of a Croydon Youth Council as this could be used as a vehicle or channel for the youth to influence the decisions that affect them.Policing along with social work should and must be protected from budgetary cuts as they are at the header of fighting crime.ConclusionEliot Spitzer the former American Democratic politician once remarked The world has conducted a macro-economic experiment since the cataclysm of 2008. In Europe, the fans of austerity have had their chance, and the results have been a disaster. Unquote.This essay has stated the case why austerity measures, in other words, social and economic policies are impacting on the day to day lives of people mostly young people. The current government and its predecessor the Conservative/Libera l coalition continue to deprive young people of opportunities that could have made them better people or leaders of tomorrow and unfortunately their policies will continue to impact badly on how social workers deliver their duties in the communities they serve, as they fetter their ability to practice. People are losing services essential to their well being and that cannot be good for the well being of their mental state.The British Association of Social Workers Code of Ethics states that principles of human rights and social justice are fundamental to the work of a social worker it can therefore be argued, how can social workers foster a just environment when they have to work under an austerity environment which is unjust and cannot support them.This essay argues that austerity is state sponsored human rights abuse.Words 2985Areflective summary response to the feedback from peers on the formative presentationBruce (2013) argues that the process of reflection can be described as the detailed thinking you may undertake about an event or experience, and the new perspective or knowledge you gain as a result of this process.The compliments my group received from peers about how well we worked together as a unit resonated well with and reinforced the theoretical framework stages of group development described by Tuckman (1965) as norming, forming, storming and performing.Our group was not that difficult to form as we already had developed interpersonal relations through meeting in the canteen and lectures. Interestingly, due to being the eldest in the group, I seemed to command respect from group members as they presumed being older made me wiser. However some members felt age should not be a criterion for choosing a group leader. As I had already studied each group members strengths and weaknesses, I simply told them the reasons why they should choose me, at the same time delegating duties for the presentation. Everyone seemed happy with the delegated duties an d so the team structure took shape. At the norming stage we set up a collaborative strategy through a whatsapp group. A member would post their idea of the delegated role then we would all look at it and have our input. We found this to be an excellent medium of communication and sharing of ideas. At this stage we also lost our 6th group member due to pregnancy.Our feat stage appeared to be the easiest as each member wanted the group to succeed. Great and not so great ideas flowed from members as we worked hard to meet the deadline. We complimented each other where it was deserved.It can therefore be argued that the group formation process of our team was an event I have just reflected about.Words 339A neat evaluation of an interview undertaken with a captain about their role and experiences of providing services in a community-based organisation.Interviewing a arrest AssessorWhen planning for my interview I thought about Egans (2014, pg.136.) use of probes to explore and clarif y points of view, decisions and proposals. This gave me an idea about how I was going to probe the nurse so she could engage and tell me in detail the scope of her role and challenges she faces in her role. I was very interested in the direct positive impact she was having on the community hospital too.This community hospital is what could be described, as, argued by Cunningham and Cunningham (2008) a traditional geographic community due to its location and shared space, proximity and years of shared experience which are seen to have inculcated certain common values and norms and there is a sense of permanence, shared responsibility, duty and mutual support.Adams et al in Brint (1994) argue that an organisation should have valued professionals who combine expertise with the technical capacity to solve problems, particularly major global problems such as health and the environment.My interview was with a Nurse Assessor for an intermediate care services (IMC) in a community hospital. She stated that her role sometimes included working in front of the house, incident and Emergency (A and E) admissions avoidance and stated that she found this sort of overwhelming. I asked why she had to perform a role which appeared to be outside her remit and her response was that even though she had been trained for the role, there was a serious lack of qualified personnel so she and her colleagues had to rotate and share duties.She does not specifically do social care but because they work as a team, she tends to sign post to social care if patients do not fit the IMC criteria for rehabilitation. This role is currently evolving as they are working as an integrated discharge team that is, working in teams with social workers and hospital discharge coordinators to facilitate early and timely discharges. It was quite interesting how her role processes are not that dissimilar to those of a social worker, starting with assessment, moving through to planning, intervention finally m onitoring, evaluation and review. Adams et al (2009). concisely the team is transitioning from using social care policies towards what is called a Trusted Assessor who can do all three roles, meaning that they will have to work within social care policies and legislation while assimilating the trusted assessor concept. It is a work in progress.The challenges related to her role are mainly friction in teams working collaboratively and no clear cut boundaries, hence blurring the roles. Above all, keeping up with the pace of the changing face and needs in Health and Social Care and the aging population was another challenge they had to deal with as a team on a regular basis. acquire outstrips supply and the need for services has been outstripped by lack of growth in infrastructure. She felt that her professional values were being compromised by the pressures of work. Reflecting on what she had told me, I referred to Hertzberg et al (2010) who argued that work motivation is intrinsic t o the job and that conditions of employment and relations in the workplace have the capacity to demotivate.In this new structure of collaborative care (integrated discharge teams) she works with three social workers in the team.They work together to facilitate. She refers and discusses relevant cases with them and they in turn will discuss and refer some patients to her if they feel that their needs can be met in intermediate care even if it means accessing IMC to reduce the care package.After the interview I was left with a myriad of dilemmas, but the one that stuck to my mind was how the generality of healthcare professionals are victims of legislation probably designed by people who spend most of their time looking for mistakes than solutions, as can be seen by the bad press that they usually get. Healthcare workers are supposed to abide by and adhere to certain statutes yet their professional competencies are being hindered by a lack of resources.

Literature in No Drama Essays -- Literary Analysis

By nature, Japanese No drama draw much of their inspiration and influence from the classics. Many are establish on episodes from the most popular classics, like Atsumori, based on the Tale of Heike, or Matsukaze, which was actually based on a collage of earlier work. plane within these episodes do we take place references to yet more classic works of literature, from the oldest collections of poetry to adopted religious texts. That isnt to say that No is without its avow strokes of creativenessthe entire performance is a unique adaptation, and the playwrights had to be both highly educated in the classics, yet geniuses at the creative aspect of weaving birdsong/poetry, dance, religion and literature together into a heart-wrenching spectacle.It might be easier to behold the similarities between no plays than the differences. The basic plot changes little there is a traveller or monastic who encounters a restless ghost or ghosts whose restless souls must be put to rest. The religious implications here are major, and become a central theme of No. In both Atsumori and Matsukaze, the monk chants Namu Amida Bu, for the Pure Land sect of Buddhism, as well as recites verses from the Lotus Sutra. The commentary mentions that The monk invokes Amida for the spirits of the dead, although the dead are comforted more often with passes from the Lotus Sutra. (p.41) Atsumoris ghost, as character youth, and Rensho, a monk, both quote together If I at last become a Buddha/then all sentient beings who call my Name/in all the worlds, in the ten directions/will find welcome in Me, for I abandon none, which is from the sutra known as Kammuryojukyo. The chorus expands on this quote until the end of the scene, the song being the playwrights own creati... ... have a friend. (p.40) Matsukazes text refers to a great deal more older poetry than Atsumori, perhaps simply because it is more relevant and take into account in the context of the story Matsukaze is a love story, and there is a lot present in the classics about love. Another kokinshu poem found in Matsukaze From the pillow/from the foot fo the bed/love comes pursuing, (p.202) for example. The examples of the samples of poetry, and allusions to other works of literature, are so numerous and some so subtle that they are innumerable in No drama. No could not exist without the classics that it constantly draws upon. This calls for a highly educated audience to enjoy the play in its entirety. However, for the medieval age, it was spick-and-span and exciting to see these classics woven together in a stage performance, so gracefully and creatively by the playwrights of old.

The American South :: American History States Papers

The American SouthSo youve moved, or been moved, to the South. Or maybe youre thinking about it. Youre wondering What is this place? Whats different about it? Is it different, anymore? secure questions. Old ones, too. People have been asking them for decades. Some of us even make our livings by asking them, but we still dont agree about the answers. Lets impression at what might seem to be a simpler question Where is the South?Thats easy enough, isnt it? People more or slight agree about which split of the United States are in the South and which arent. If I gave you a list of states and asked which are Southern, all in all, chances are youd agree with some of my students, whose answers are summarized in Figure 1. I dont share their hesitation about Arkansas, and I think too many were ready to put Missouri in the South, but theres non a lot to argue with here.That tells us something. It tells us that the South is, to begin with, a concept and a shared one. Its an idea that people can verbalize about, think about, use to orient themselves and each other. People know whether theyre in it or not. As a geographer would put it, the South is a vernacular region. closure and think about that. Why should that be? Why can I write South with some assurance that youll know I mean capital of Virginia and dont mean Phoenix? What is it that the Souths boundaries enclose?Well, for starters, its not news that the South has been an economically and demographically distinctive place a poor, rural region with a biracial population, reflecting the past dominance of the plantation system. One thing the Souths boundaries have set off is a set of distinctive problems, growing out of that history. Those problems may be less and less obvious, but most are still with us to some extent, and we can still use them to locate the South.But the South is more than undecomposed a collection of unfavorable statistics. It has also been home to several populations, black and white, whose in tertwined cultures have set them off from other Americans as well as from each other. Some of us, in fact, have suggested that Southerners ought to be viewed as an American ethnic group, like Italian- or Polish-Americans. If we can use distinctive cultural attributes to find Southerners, whence we can say that the South is where they are found.

Global Power Dynamic Essay -- International Relations

IntroductionDuring the era of the Cold War, the global agency structure was characterized by strategic bipolarity (Sorensen 2004 124). After the disintegration of Soviet Union, the global power structure turned into a unipolar world under the control of the United States. With the development of Germany and Japan, scholars, analysts and observers have predicted a decline in American power and a return to a multi-polar world. Recent years, the BRICs has been considered as a new power in global issue. its rapid and successful development, mainland mainland China has been exposed under the spotlight all the time. The world economic crisis happened in 2007 not only damaged the economy of America but also the outside(a) image.

After the global economic crisis, China has reduced the quad with America in economy, most importantly China has built a powerful image in the world. Thus this image brings one standpoint that China is becoming another super power in the world America cannot dictate the whole world any more. Based on this view, the global power structure is emerging a G2 structure China and US (Stelzer 2009). This paper is aiming to analyze this G2 assumption. Is it the real global power structure in the world outright? How does the crisis affect the state? Does the world economic crisis only bring power to China?
