Oceanic Domain Awareness An Imperative Environmental Sciences Essay

Modern naval scheme is basically based on assorted agencies to turn up possible enemy forces across the oceans, a job complicated by the enormousness of the maritime environment, the immense figure of legitimate users, and the broad assortment of agencies by which an enemy can work the oceans to his advantage. The oceans are complex mediums whose nature provides ample chance for an enemy to avoid detection-weather, sea provinces, and coastal land masses all present considerable challenges to modern detectors. Peacetime economic usage of the seas complicates this job tremendously. The oceans are the universe ‘s foremost ( and arguably most unregulated ) main road, place to a huge and broad assortment of international impersonal transportation that possess no evident menace. Determining the enemy in such a crowded and complex environment is hard during conventional war, during an asymmetric struggle such as the planetary war on panic ( GWOT ) , it is a formidable undertaking. It is the asymmetric nature of GWOT that forms the nucleus of Maritime Domain Awareness ( MDA ) . In conventional naval war the enemy is comparatively good defined and about universally a battler. In GWOT, where literally any vas could be a possible enemy or arm bearer, or when any nautical event can hold an impact on the security of India, demands a much higher degree of consciousness than that usually required in a conventional naval struggle. This is recognised by the formal definition of MDA as articulated by the US authorities vide their document National Security Presidential Directive 41, 2004: – Maritime Domain Awareness is â€Å" the effectual apprehension of anything associated with the planetary maritime environment that could impact the security, safety, economic system or environment of U.S. This is accomplished through the integrating of intelligence, surveillance, observation, and pilotage systems into one common runing image ( COP ) that is accessible throughout the U.S. Government. Unlike traditional naval operations, it is evident that the end of MDA is far more than merely looking for possible maritime enemies poised to assail India. The deductions of â€Å" Anything associated † with the maritime environment that can impact the security, safety, economic system or environment go far beyond a authoritative maritime menace. As per the US reading, these include smuggling of people or unsafe ladings, buccaneering, proliferation of Weapons of Mass Destruction ( WMD ) , designation and protection of critical maritime substructure, oil spills, conditions, and environmental concerns among other events. Nautical events that could potentially impact India are non the lone wide-ranging component of MDA it is besides indispensable that menaces be identified as early and far from the seashore as possible. The planetary nature of MDA activities happening overseas and in foreign ports is really much a portion of MDA. For illustration, if a lading is loaded in Aden and its ultimate finish is India ( via several other international ports ) , the burden, conveyance, security, and all affairs associated with that container would be portion of MDA. MDA must hence be exercised over all oceans worldwide, and potentially cover all nautical involvements that finally impact India. Puting in topographic point an effectual MDA is a powerful undertaking sing the scope of possible security challenges and tremendous geographic country represented by the maritime sphere. In India a overplus of bureaus possessing a broad scope of operational and intelligence capablenesss would necessitate information merg er under the over-arching MDA. Although many factors are considered in MDA, its nucleus procedure is finally the monitoring of vass and the vass ‘ lading, crews, and riders to quickly bring forth geo-locating information on vass of involvement. This is an analytical procedure that includes trailing, informations base hunts for unknown linkages and anomaly sensing. Cardinal to this is the sensing, monitoring, tracking of vass. This tracking procedure is comprised of five elements designed to concentrate on a narrow country of tactical dimension where menaces can be identified and isolated viz. ; Maritime surveillance, Detection, Tracking, Classification & A ; Identification and aiming. Targeting involves construing sensing and designation information fused with intelligence to screen vessel purposes and determine hazard. MDA ‘s nucleus is using the vas tracking procedure to a superimposed defense mechanism theoretical account centred on the coastline of India, the ultimate end of which is to observe possible menaces early and as far off from the Indian coastline as possible. As there is no individual high value unit to protect MDA â€Å" beds † are expanded to include an full coastline with the overall end of co-ordinated surveillance. Not all countries in these â€Å" beds † are considered every bit, but instead extra attending is given to countries that are possible marks for the terrorist/enemy. The US has the 2000nm bound of the Maritime sensing and Identification zone MDIZ it is based on the legislated 96 hr presentment demand for foreign vass come ining U.S. ports. A vas going 20kts will get at its finish in approximately 96 hours. MDIZ ‘s purpose is to garner more timely information on the vas as it approaches closer to the U.S. seashore. When come ining the MDIZ, places every four hours are the norm while in territorial Waterss the end is to obtain positional informations every 3 proceedingss. There are many systems that could supply a high grade of surveillance and tracking informations, but the existent merger of this information remains a job country. In order to deduce a comprehensive MDA image, information demands to be fused, correlated, and analysed and for it to be relevant to national security it must be designed to run cohesively at tactical, regional and strategic degrees. Strategic MDA On the national degree, nautical scheme is critical for long term planning, operational penetration, and supplying national determination shapers with support to set up precedences, determine schemes of mutualist administrations, allocate national resources, and determine degree of overall maritime menace This is a hard procedure during normal peacetime operations and is peculiarly ambitious in the invariably altering asymmetric maritime environment that MDA is designed to turn to. MDA ‘s ultimate end is to obtain a sense of planetary consciousness that reaches beyond the confines of the tactical and regional degrees. If MDA was merely a defensive scheme against a known military or terrorist menace, it could be obtained by organizing defensive beds around India. But as an informational/awareness system, its ends are far broader, seeking to understand all possible maritime menaces to India, many of which could arise overseas in an unoffending mode. Strategic MDA requires a wide position and capablenesss at the highest degrees of analysis, intelligence, and policy. It requires the realignment of bureaucratism and the re-tasking of national assets toward the overall end of planetary consciousness. A Centre for strategic MDA must hold experience in multi-organisation operations and processs that can exceed the spread between the armed forces, jurisprudence enforcement, and regulative bureaus that are portion of MDA. In the maritime sphere, this is possible through enlargement of bing substructure, specifically developing such a fusion/analysis point. Two countries of detector engineerings that have peculiar pertinence to strategic MDA are a orbiter based feeling capableness and a net work of submerged surveillance detectors.Structure of the Indian MDAThe 26 Nov 2008 onslaught on Mumbai has been analysed and security spreads addressed to explicate the MDA. The cardinal rule for the MDA has been the application of informations blending to acquire actionable int elligence inputs to mensurate, comparison and place and prosecute and forestall sea-borne condemnable activities. The figure of different bureaus at cardinal and province degree involved is 13, and hence effectual coordination is an issue. Some of the enterprises include: – – Launch of GSAT7 orbiter in geosynchronous orbit by lSRO, with Rukmani terminuss ( ex Israel ) placed on Major war vessels for instantaneous informations transportation to run into the demands of the Navy. ISRO is besides likely to set in topographic point by 2013 the Indian Regional Navigation Seven Satellite System ( IRNSS ) which would supply informations within 1000 stat mis of India. – Puting up of The National Command Control Communication and Intelligence web ( NC3IN ) . – The puting up of a radio detection and ranging concatenation ( X band AIS receiving system VHF and Electro-Optics ) of 46 detector Stationss being linked with the AIS inputs ( Covering the full Indian seashore ) , and LRIT and Vessel Traffic Management Systems. Coastal secret plans are maintained by the ICG Regional HQs to back up the Joint Operations Centres ( JOCs ) set up following to naval nautical operations suites ( MORS ) in all naval bids and at New Delhi. – Puting up of Multi Agency Centres ( MAC ) for intelligence inputs and studies. – Registration of fishing vass by provinces, and proviso of battery operated Distress Action Terminals ( DATs ) for vass below 300 dozenss. DG Shipping would supply smaller fishing boats with AIS transponders which has enforced ISPS codification for Port security with port security programs. Supplying Biometric /recognition individuality cards for fishermen which can be identified on a machine on board surveillance platforms. – Puting up of a Marine Police force with 73 Coastal constabulary Stationss across 9 provinces and provided with 5 and 10 ton trade which can police inshore Waterss. – A uninterrupted outline of record of transporting with World Customs Organisation has been enforced and MARSEC security degrees are exercised and coastal villagers educated on demand to be argus-eyed by the IN and ICG. – The Indian Navy has instituted Marine Commandos Rapid Reaction Forces and a Sagar Prahari Bal ( SPB ) of 100 mariners who are being equipped with 80 fast interceptor trade ( FICs ) for protection of naval bases, VAs and VPs. UAVs and Aerostats are besides planned for initiation. – Coordinated coastal and seaward plus patrolling has been strengthened by the IN and the ICG. – All stairss for MDA are networked with the Indian Navy ‘s fleet of ships, pigboats and MR aircraft. The Government of India has put in topographic point a formidable program for MDA, and the single systems are being setup prior to concluding integrating and fusing of informations. It is expected that the MDA would be to the full functional by 2015. However, in close hereafter it can be presumed that Indian Navy would draw a bead on to get formidable sea denial and sea control capablenesss. It is opined that the footings Sea watch/denial/ control are likely to spread out and transform in to ‘Oceanic infinite watch/ denial/control ‘ . The term Oceanic infinite denial/control would encompass a cylindrical infinite in 3D+ dimensions ; that is the sea surface, the atmospheric volume above, the outer infinite at least up to low Earth revolving satellite highs, the H2O volume up to the sea bed, the sea bed itself and besides security of the deep sea mining assets in the EEZ. ( Opinion of the writer ) . The above premiss implies that a broader pelagic skyline is in fact inclusive of non merely extended and broader spacial operating sphere, but besides much wider and broader raid in to the verticals below the surface to the sea bed and above up to fringe of the ambiance. Unless deductions of this nature are anticipated and factored in, technological prognosiss themselves would drag behind the rapid progressing gait of engineering and the synergisms being achieved due to harmonization and version inter and intra scientific Fieldss. Therefore it is imperative that holistic positions into the information consciousness sphere include the pelagic sphere consciousness every bit good as it ‘s connect with India ‘s security and MDA. Oceanic Domain Awareness Scientific survey of the oceans originated in U.S. basically as a map of national security. Probes that focused on the tactical and operational impacts of the fluid, geophysical, chemical and biological Marine environment upon U.S. Navy operations successfully addressed many disputing naval demands ; but oceanographic enquiry in support of naval demands besides triggered unexpected consequences. In many cases the cognition of the oceans that was acquired through directed surveies – and through complementary lines of enquiry that were enabled by tools developed for naval oceanographic research – farther wedged national security in ways that were non anticipated and which transcended tactical and operational significance and could be considered of more strategic effect. The primary drift to the rapid development of oceanology during its twentieth century yearss as a scientific discipline is without a uncertainty the pigboat and the cardinal alterations that occurred when naval warfare became genuinely 3-dimensional. Prosecuting pigboats was executable chiefly through the transmittal of submerged sound, actively by echo sounder to echo-locate marks and passively by listening hydrophones and triangulation. The range of oceanographic attempts in the chase of the pigboat opened all of the oceanographic subjects ( physical, chemical, biological, and geological oceanology ) to increased investing, research attempt and – significantly – to integrating. Twentieth-century oceanology was basically a security-based enterprise to cut down the opacity of the oceans to antisubmarine warfare in WWI, WWII and the Cold War, and harness that opacity for violative pigboat operations, along with a host of other security based naval concerns. In the ocean scientific disciplines, new engineering necessarily leads to new finds and to cardinal progresss in basic cognition. In the old ages following World War II, the first global-scale function and sampling of the seafloor by oceanographic research vass led straight to the find of seafloor spreading and the development of the theory of home base tectonics which has since revolutionised thoughts of Earth construction and development. A decennary subsequently, the first geographic expedition of mid-ocean ridges utilizing deep-towed vehicles and manned submersibles resulted in the singular find of deep-sea hydrothermal blowhole communities with antecedently unknown signifiers of life and a huge, still mostly undiscovered microbial biosphere below the seafloor. Over the past two decennaries, ocean physicists, chemists, life scientists, and geologists have used a assortment of tools, from instrumented buoys to deep-sea boring, to redefine their apprehension of the ocean ‘s f unction in commanding conditions and longer-term clime alteration. The ocean scientific disciplines are now on the threshold of another major technological progress as the scientific community begins to set up a planetary, long-run presence in the oceans in order to understand the temporal variableness of ocean systems on clip graduated tables runing from seconds to decennaries or longer. This chance arises from the meeting of a figure of emerging new technological capablenesss, including: – – Telecommunication engineering ( e.g. , orbiters, fiber-optic pigboat overseas telegrams ) that makes possible real-time telemetry of huge measures of informations to shore every bit good as real-time synergistic control of instruments in even the most distant parts of the deep sea ; – Telecommunication overseas telegrams that enable important degrees of power to run instruments from the sea surface to the deep seafloor ; – New detectors that make possible in situ measurings of physical, chemical, and biological procedures ; – Computational and patterning capablenesss to construct more realistic, multidisciplinary, and prognostic theoretical accounts of ocean phenomena ; – Data archival systems that can hive away, pull strings, and recover immense volumes of informations from arrays of detectors ; and – Computer webs that can convey real-time informations to the desktop, which could potentially immensely increase engagement of research workers, pupils, pedagogues and the general populace in ocean research and find. An illustration of a double usage observatory is the Sound Surveillance System ( SOSUS ) , a classified system developed by the U.S. Navy in the late fiftiess to observe, path, and sort Russian pigboats utilizing arrays of submerged hydrophones. SOSUS is a web of acoustic arrays in which hydrophones are connected to a shore station by a pigboat overseas telegram. Research workers with security clearances have used the system for productive surveies of mid-ocean ridge volcanic-hydrothermal systems, marine mammals, and acoustic thermometry. SOSUS has besides provided the research community with technology know-how that will be relevant to any cabled web of ocean observatories. One lesson from the U.S. Navy ‘s SOSUS type of arrays is that the acquisition and public distribution of acoustic and other geophysical informations in some parts along a state ‘s coastline poses a important national security hazard. Technologies ( e.g. , robust detectors and substructure, independent vehicles ) must be developed to heighten informations aggregation in all conditions conditions to back up high-spatial declaration and near-real-time prediction throughout the Open Ocean and coastal zone. Supplying accurate and comprehensive environmental information will necessitate spread outing experimental webs to supervise, record, and present real-time, surface-monitoring informations ( e.g. , high-frequency, coastal-based radio detection and rangings ) . This enlargement will necessitate progressing detector and engineering development, peculiarly for independent and relentless observations, every bit good as for long-run detecting systems ; spread outing real-time or near-real-time informations aggregation on environmental variables by integrating experimental capablenesss of ships of chance ( e.g. , fishing, lading, and rider vass ) ; and heightening automated and independent bottom-mapping capablenesss for alteration sensing to better rapid, all-out study programming. Datas collected by the detecting systems must be accessible through a comprehensive national information web, either through a individual system or a distributed web. Developing this information web will necessitate new methodological analysiss that address spreads in informations aggregation, sharing, and interoperability of engineerings, and should allow integrating of bing research into operational systems ( e.g. , systems supplying real-time pilotage informations to vass ) . This information web should be able to associate with other databases, such as those concentrating on ecosystem informations, and developed in conformity with international criterions for informations exchange. The national information web will besides supply the informations needed for theoretical accounts imitating multiple scenarios to better understand possible impacts, conditions events or semisynthetic breaks on Marine operations, and to back up operations Restoration programs. The seashore and unfastened ocean are critical spheres for the security of a state with sea as boundaries, both at place and abroad. National-security operations in the ocean take topographic point globally and frequently require uninterrupted, near-real-time monitoring of environmental conditions utilizing tools such as independent detectors, targeted observations, and adaptative modeling. These capablenesss, combined with improved apprehension of the ocean environment enabled by other ocean scientific discipline research activities, will back up accurate ocean-state appraisals and let hereafter forces to carry on joint and combined operations in near shore and deep-ocean operating environments, anyplace and at anytime. In position of the treatment above it has been brought out that the MDA needs to be integrated within pelagic sphere consciousness for completeness of maritime cognition, the deficiency of which can take to serious effects as has been brought out in a recent appraisal of naval exercisings and arm fires in the US, where it was found that over 90 % of them were affected adversely due to amiss assessed or small known environmental factors. In an existent struggle, these would hold led to mission failures. This lone under-pins the fact that Oceanic Domain Awareness is an enabler for the hereafter and an jussive mood for a state like India.

Are Technology Advances Bad for Society?

Steven Thai Ms. Katie English 110 Feb 28th, 2013 Are Technology Advances Bad For Society? Over the past 30 years, humans always tried to create something that helps us reduce the amount of work we have to do. Games were created to help human release our stress while mobile phones help us to call and access the internet anywhere we want. Technologies really help us in every task of our life. However, technological advances are bad for our society because of addiction, censorship, and they may lead us into another technological weapons war between countries around the world.First consider how addictive technology has become. According to Sherry Turkle from TED Talk, her daughter spent time with her friends together looking at their mobile phones devices (Ted. com). These kids had so much fun on their mobile phones that they didn’t even look at their friends. On the other hand, technology became an essential part of our lives right now. Most of us spend time with our electronic d evices that we forget where we were standing, what we were doing, or what is the purpose and objective of our life. What makes us addicted to mobile phones?Nowadays, we can do almost everything with our cellphones, such as playing videos games, accessing social networks, and watching videos online. These things have become too addictive to us, and we have spent so much time on such devices. Look back to 20 years ago, back when the time technologies were not very common compared to today. Eventually, we spent more time with each other; we hung out with friends. Technologies are advancing so rapidly that we have become addicted and have forgotten what surrounds us. Some people might argue that there is also a good side of technology advances.According to Dr. Rick Nauert, a Senior Editor of Psych Central, there was an unexpected discovery that playing video games helped human-beings reduce the production of the stress-related hormone cortisol (Psychcentral. com). In order to prove this , Dr. Nauert recorded a group of 23 newly recruited employees of a Montreal-based call center to play games. Later on, he found an amazing result that the games showed an average 17 percent reduction in cortisol production compared to the group who did not play games (Psychcentral. com). This showed that echnology advances can be applied for good purposes to our life. Although technologies help us to reduce the stress related hormone, it brings to us many health problems. Dr. Ripudaman, a master in science and a frequent computer user, claimed that there are heaths concerned when you sit and work in front of the computer for a long time, such as eyes problems from bright screen, and wrist ache after working at the computer all day (Ripudaman). In addition, if we keep using the computer for a long time, these problems grow bigger.We might have joint problems, and our eyes have to work a lot so they get worse, in which case it costs us a lot of money for eyes and back surgery (Ripudam an). Another thing to be concerned about when we use technology is government censorship. You would feel bad if you lost your own privacy when the government tracked down your phone record, and eavesdropped on your phone call. This is the world when you need your own privacy, but most of our technological devices such as cellphones and laptops are tracked down by our own government every minute.According to Jennifer Valentino, the FBI was concerned by the citizens when they had the rights to access people’s phone record after the attack of September 11th, 2001 (Devries). Additionally, Professor Stephen Vladeck from American University Washington College of Law had put a good question to all of us; â€Å"How can you protect the First Amendment rights at the same time as you protect the government’s interest in secrecy? † (Vladeck). More importantly, no one among us would have see that our record had been tracked down, which should be a concern for an individualâ €™s freedom.Others might claim that the government is doing the right thing in order to protect national security. By tracking down citizens’ record the government can easily find terrorists, who are trying to attack their country. After the incident on September 11th, the concerns over the government keeping track of people’s technological devices who they suspected as terrorists and a threat to the country (Vladeck). To answer for that, we should take China as an example; where the presses have been ranked as â€Å"not free† by Freedom House (Wikipedia. rg). In China, everything is monitored by the government mostly technological devices. We feel bad when our privacy are managed by the government. Therefore, these technology advances are not helping our life get better. Furthermore, technological advances help the government to access our privacy easily compared to our past 50 years. It leads us to a question, should we continue to use devices like cellpho nes, laptops or smartphone when the government is monitoring our activities through those devices?Lastly, technological advances can lead us to a world war. Countries with strong economies like the United States, China, and Russia always compete to have the strongest technologies for weapons in their hands. The rapid changes in technology help many countries in the world to create their own weapons, tanks, aircrafts, and nuclear bombs. Why are these countries are competing for war technology advances? Take a look at it this way, when a weapon or a bomb is created, it will be tested in Iraq or Afghanistan.There will be more deaths and bigger destruction as the technology of those weapons further advanced. The founder and leader of the Muttahida Quami Movement, Altaf Hussain, has brought us great attention to a possibility of a third world war, where these imperial powers continued to act in a presumptuous manner in world affairs (mqm. org). In fact, world powers countries should stop competing for war technologies advances with each other in the present world to make a better world, to bring peace to those countries whose need it.However, there are others who oppose that the United States and Russia are creating nuclear bombs and missiles defenses to protect their own national security. In reality, they are creating these defense systems to make other countries to be afraid of them. The more weapons and bombs created, the more deaths and destruction the world has to suffer. Instead of using billions and billions of dollars to make technological advances that kill people, we should use that huge amount of money to improve education, health care, and reduce the amount of starvation.There will be more people will feel happy as the government will use money to solve social and political problems. In general, by not using money to develop war technological advances, we can save a lot of lives, rather than killing them by weapons, bombs, and missiles and so on. In co nclusion, technological advancement has seen many negative impacts on our society; it causes unhealthy addiction, encourages government censorship, and might lead to another destructive world war. We must stop using technology devices, we should stand together to stop these bad problems from our life.For the great future of our young generation, for the better living of our life, we must stop the bad effect of technologies on our life.

Tech Article - Essay Example So the work of the technology is to identify all moving objects with the aid of computer chipped tags. Lui and Chen 2009, in their article titled â€Å"Applications of RFID technology for improving production efficiency in an integrated-circuit packaging house†, defined the radio frequency identification (RFID) as an emerging technology that can be used to expand the possibilities for data capture. They stress that one of the primary use of the RFID technology, is for process control and material handling applications which can produce benefits of flexibility and interactivity. (2203) Potential impact for companies Lui and Chen 2009, explains that an integrated-circuit (IC) packaging house must be able to provide clients with instant and accurate information on its products and services. In other to do that properly, an IC packaging house must keep track of all its wafers, regardless of whether those wafers are in packaging, testing, or shipping. In other to achieve this, the company combines the RFID technology with an enterprise resource planning otherwise known as an ERP system for resolving various wafer receiving and inventory transaction problems. An electronic control system is thus developed using Oracle application implementation methodology or (AIM) to integrate RFID technology and the ERP system.

Non Profit Organizations Research Paper Example | Topics and Well Written Essays - 2000 words

Non Profit Organizations - Research Paper Example The friend should expect a great deal of difference as per her working domains. For starters, she must understand that this is a wholly differential undertaking and it would mean that she will have to undergo work which is haphazard and without any due incentives coming to her fore. She will have to comprehend how as being the Marketing Manager at Coca Cola will she replicate the same within her realms at the not for profit organization. There is evidence in the form of understanding that the not for profit organizations do not bring in that many incentives and bonuses which Coca Cola might promise at any given times. This is suggested by the company policies of the two institutions – the not for profit organization and Coca Cola. Since Coca Cola is a thriving business which is based upon the premise of raking in a profit on all counts, the not for profit organization does not exist as such1. There is reason enough to believe that the not for profit organization would bank sol ely on getting the job done and would not warrant any benefits for its employees in the long run. Therefore, one must understand that the giant corporate enterprise (Coca Cola) would be better placed to give her a better career opportunity than the one which has been promised by this not for profit organization.... This is not the case within her role at Coca Cola where she worked as the Marketing Manager. She should expect to see that people are more laidback in their nature whilst working for the not for profit organization as they do not receive any benefits as such. This would mean that there are anomalies of different kinds and shapes within the reins of the organization2. Also what is important here is an understanding that Coca Cola believes in catering to different audiences all over the world and its scope is more broad which is not the case with the not for profit organization where their limitations are many and their incentives are minimal to state the least. In essence, these are some of the most important issues that could be drawn up within the realms of the comparison that is done for this friend whilst choosing the not for profit organization over her present day Marketing Manager role at Coca Cola. 2. You are the Marketing Director of a non profit organization focused on promo ting healthy eating habits of young school aged children. How would you do this? As the Marketing Director of a non profit organization which basically believes in inculcating healthy habits within kids to eat good food, I would first and foremost ask the publics to engage with my organization in an able capacity. Since I am the one who would have to oversee the reins of the non profit organization, my role becomes magnanimous all this while. I would have to find ways and means through which my company can move forward with distinction and a sense of ease and empathy coming from the realms of the different players that are present within the non profit industry as well as the general public for whom my organization is in operation. Therefore, my role becomes

Advertisement appeals as put forth by fowles Essay

Advertisement appeals as put forth by fowles - Essay Example The consumers develop resistance to the adverts of which the advertisement agencies try to use different appeals to reach out to the consumers. The level of penetration depends on the willingness of the consumer to listen or watch the advertisement appeals. Advertisement Appeals as Put Forth By Fowles According to Fowles (2) the advertisers make efforts to thwart the rational, guarded, doubtful clout acquired by the consumers when choosing the brands to buy. Most consumers develop a certain clout around their thinking which the advertisers try as much as possible to avoid. In doing so, the advertisers make effort to appeal to the consumers to prevent reacting without thinking but to pay attention to the fundamental ideas or information being passed through the adverts. This helps the advertisers to realize their main objectives in the advertisement campaigns. There is the utilization of the subliminal plea. This refers to the remarks which are directed to the conditions as well as th inking amongst the merchandisers. It is noted that most buyers and consumers are normally resistant to adverts or develop some form of opposition to the adverts. According to various studies most Americans are exposed to different forms of adverts which come in different media such as the televisions, radio, newspaper, billboards, and direct mails among other media. The consumers try their best to develop a filter in regard to which adverts to listen to or read or watch and which ones to ignore. The advertisers make efforts to be tactical in order to get access to the subconscious mind. Moreover, the advertisers make use of the personality appeal and the need to nurture. This is because there is a presumption that the character of consumers is unique. It also presumes that human beings have different range of unmet urges or desires which must be fulfilled through the advertisements aired over the media. There are appeals such as tenderness, ambitions, lust and susceptibility hence t hey seek resolution. By use of the personality appeal, these mental appeals must be met in order to be receptive to the advertisements being aired over the media. Nevertheless, it always difficult to penetrate through these unfulfilled desires of which other types of appeals must be used to supplement this form of appeal to the consumers. In addition, advertisers make efforts to appeal to the consumers by use of the exceptionally selected pictures of images. This is meant to trigger the shell of consciousness the consumers have developed. The images may be that of celebrities identified by the consumers, female models or very nice looking children. Some make use of the text while the majority makes use of the artwork. It is in the assumption that visual adverts are best appropriate for more primeval parts of the brain system. The consumers can easily be hooked when this form of appeal is combined with impression of satisfaction for stated intention. However, most adverts are always prejudged by the consumers with the type of content in the sense that majority tend to give the impression that if the consumers lack something, they have a solution or substitute for fulfilling their desires. Another form of appeal for most adverts that are aired over the media is the intense running force in the thoughts of the consumers.

Understanding the class Essay Example | Topics and Well Written Essays - 500 words

Understanding the class - Essay Example I prepared a few questions which I anticipated to be asked by the instructor so as to be o track during the class session. I tried as much to resist any distractions. I did this by sitting in a position of class where disruptive classmates are away from. I always put myself in the learning mood, focused on the instructor. I listened actively and took short notes in order for me to comprehend more. During the course of the semester, I shifted my position quite often for to remain alert during class time and tried not to distract myself by use of a phone or talking to my neighbor. During the class sessions, I learned that love involves feelings and emotions. It is a powerful affection of which makes one to be happy and show contentment. Knowing happiness means feeling cheerful and contentment in a manner that one feels satisfied. Love also is a form of human compassions and kindness. This explains how through it, we can feel the fullness of life. Love as a noun describes something adorable. Love as noun means that it is adoring feeling of deep affection between two people. It refers to another person as a beloved person involving desire. It can be something liked or showing affectionate concern toward others. Love as a verb is an action. This means that love expressing love towards another person or something. The action of showing love or showing affection explains love as a verb. As a verb, love can be used within the context of action whereby two people are involved in kissing or embracing each other. By attending class sessions, I understood that sexual identity is important for the development of an individual in terms of self-esteem and one’s self confidence. Sexual identity gives a person an opportunity to understand who they are and who they are sexually attracted to. Personal identity is defined by sexual identity of an individual. The two go hand in hand in that personal

I strongly believe that workplace must be attractive enough so that one can devote maximum time there willingly and not out of compulsion. I would like to earn prestige from my colleagues and seniors through my hard work and commitment and therefore organization should provide me enough leeway to go ahead in my chosen field. That is what precisely I mean by prestige and why it is important to me. I know that I will be able to climb higher ladders in my career path through my zeal and devotion to the work that I willingly choose. So I am not concerned about salary as much as I am bothered about my recognition in the job and that is necessary to have a sense of achievement in my life. While pursuing my high school in Qatar, I was determined to acquire a Bachelors degree from a good university in the US. The variety of subjects in my course provides me a basic and essential understanding about several important disciplines such as management, administration, finance, managerial accounts; banking, general management; knowledge of all these subjects provide me a basic platform to choose from the numerous career paths available to me. Often, I think and work innovatively too; however, I see that ‘innovation’ in work values, in Kuders assessment is registered low. As I said I would prefer to do my work independently without much of the supervision except wherever necessary. From my self-knowledge, I can state that while working at Qatar Petroleum for almost four months, I worked with my colleagues and modified ways so that the total service time to customers got reduced by 25%. I always have a feeling that my work is important to me and I see myself as an important link in the whole chain of process to accomplish a given task.

Case assignment cultural Identity Essay Example | Topics and Well Written Essays - 500 words

Case assignment cultural Identity - Essay Example 2. To what extent do you think cultural beliefs, values, and traditions may impact health education efforts? Please provide examples of negative and positive impacts that apply to the case studies from the video. Cultural beliefs, values and traditions play a crucial role in the health-care setting. As emphasized in the National Transitions of Care Coalition (NTOCC) (n.d.), â€Å"health care professionals increasingly recognize the crucial role that culture plays in the healthcare of a client or patient and the need to deliver services in a culturally competent manner† (p. 1). Therefore, the ability of health care professionals to educate the patients on the most effective intervention would depend on the ability to communicate messages that accommodate understanding cultural beliefs, values, and traditions. In the case studies from the video, the good cross-cultural patient communication scenario clearly depicts that the following elements assist in effective efforts for health education: (1) eliciting information on the cultural remedies; (2) demonstration of acceptance of patient’s views; (3) accommodating the health beliefs of patients; (4) explores understanding of the cultural impact; and (5) empathizes and supports the patient’s perspectives and cultural views (University of Michigan: Lesson 1, 2010). On the other hand, the bad cross-cultural patient communication scenario exemplified negative impacts on health education and cultural competence: (1) not demonstrating acceptance of patient’s view; (2) not eliciting information on cultural remedies; (3) not accommodating health beliefs; and (4) not empathizing and supporting the patient’s perspectives and cultural views (University of Michican: Lecture 2, 2010). Based on the video, one would suggest to health professionals who want to improve their cross-cultural communications

Paradise Lost Essay Example for Free

Paradise Lost Essay Paradise Lost, an epic in twelve books, is in several ways one of the most wonderful of the works of men. It is one of those rare works of human genius whose power and beauty are inexhaustible. It was composed by the poet after restoration, in blindness, poverty and obscurity. Yet he produced a poem which alone is enough to give him a place among the poets who are not of one age, but of all ages, not of one country, but of the whole world giving it the genre of an immortal classic. Writing of the influences which shaped Milton’s epic, Verity says, â€Å"We must indeed recognize in Paradise Lost, the meeting point of Renaissance and Reformation, the impress of four great influences; the Bible, the classics, the Italian poets and English literature. †(Verity, 103). In allusion lies one of the chief delights of literature, and we get this delight from Paradise Lost. But the greatness of Milton’s epic lies not in allusions, not in the story, nobly though that illustrates the eternal antagonism of righteousness and wrong, and the overthrow of evil; nor in the construction, though this is sufficiently architectonic; nor in the learning, though that is vast; nor in the characterization, for which there is little scope; not in these things, though all are factors in the greatness of the poem, and in all Milton rises to the height of his argument- but in the incomparable elevation of the style, ‘the shaping spirit of Imagination’ and ‘the sheer majesty of music’. This is well explicated in the description of the flora and fauna of Eden: â€Å"†¦Ã¢â‚¬ ¦. gentle gales Fanning their odoriferous wings dispense Native perfumes and whisper whence they stole Those balmie spoiles. † (IV, 156-159) It is undoubtedly Renaissance that fired his ambition of writing an epic and his choice of its subject fell on the Biblical subject of the fall of man. He preferred the Biblical subject because, says John Bailey, â€Å"it was his belief that every statement in the Bible was literally true† (Bailey, 67). As this was also the belief of his contemporaries, his epic got recognition at once. But the use of Biblical theme hampered his freedom of invention. That is why Books I-IV, where the poet enjoyed comparatively greater freedom of invention, are better written than the other books where his imagination was hampered by his Biblical theme. Paradise Lost is a classical epic, having all the common features of the epics of Homer and Virgil. It is a long narrative poem in XII books, its subject is solemn and grand, and it finds equally grand and solemn treatment. Indeed grandeur and majesty are the key-notes of Milton’s epic. Like the classical epics, it has unity of theme and treatment. There is nothing in it that is superfluous, every episode and incident leads to the central theme – the fall of man and the loss of paradise. Wars and heroic exploits are also not lacking. There is supernatural intervention in plenty. Its characters are mostly superhuman – God and His angels, and Satan and his followers. There are only two human characters, Adam and eve. Indeed, this paucity of human actors, and consequent lack of human interest, is the basic weakness of Milton’s epic. In keeping with the epic tradition, its style and versification is lofty and sublime. Frequent and effective use has been made of Homeric or epic similes. Though Paradise Lost is a classical epic, it also has a number of unique features of its own. A classical epic deals with a subject of national importance, with the war-like exploits of some hero of national stature. The theme of Milton’s epic is vaster and of a more universal human interest than any handled by the poet’s predecessors. It concerns itself with the fortunes, not of a city or an empire, but of the whole human race, and with that particular event in the history of the race which has moulded all its destinies. Around this event, the plucking of an apple, are ranged, according to the strictest rules of the ancient epic, the histories of Heaven, Earth and Hell. The scene of action is Universal Space. The time represented is Eternity. The characters are God and all his creatures. And all these are exhibited in the clearest and most inevitable relation with the main event, so that there is not an incident, hardly a line of the poem, but lead backwards or forwards to that central theme. Like other epic poets, Milton too plunges at once into the middle of his story instead of beginning from the beginning. Thus Book I opens with an account of the Fallen Angels-Satan and his followers- in Hell, and the account of the war in heaven which resulted in that fall is given later on, in the Books V-VIII, along with the account of the Creation of the world. Satan, though defeated and fallen, does not despair. He encourages his followers, a vast hall, Pandemonium, is built, where they hold a conference to decide upon their future course of action. After much discussion it is decided that they would have their revenge upon God by corrupting the newly created man. Accordingly, Satan undertakes a journey to the new world through Chaos, reaches the Earth and the Garden of Eden. In the form of a serpent, he tempts eve to taste the fruit of the forbidden tree. He succeeds in seducing eve, and Adam, despite the warning of God’s angel Raphael, tastes the fruit of the tree of knowledge. He thus commits the Sin of Disobedience. The result is divine punishment. Consequently, there is the loss of paradise and the fall of man. Suffering becomes the lot of man as a result of this original sin. Satan, too, is punished, as he and his followers are transformed into hissing serpents. The central theme of the epic is stated in the very opening lines itself: â€Å"Of man’s first disobedience Of that Forbidden Tree, whose mortal tast Brought Death into the World, and all our woe, With loss of Eden, till one greater Man Restore us, and regain the blissful Seat, Sing Heavnly Muse,† (I, 1-6) This fall of man would be used by him to ‘assert Eternal Providence’ and ‘justify the ways of god to man’. Thus Dr.  Johnson said that Milton’s purpose is â€Å"to show the reasonableness of religion and the necessity of obedience to the Divine Law† (Brown, 82). The theme of freedom and independence is also inherent in the epic. Satan is the very embodiment of heroic energy, energy which is constantly expressed in action in his opposition to the will of god despite heavy odds. His words like: â€Å"Better to reign in hell than to serve in heaven† (I, 263) and â€Å"What though the field be lost? / All is not lost! † (I, 105-106) drives home the point very clearly. Characters in Paradise Lost may be divided into four different groups. First of all there are God, His son and His angels; secondly there are the fallen angels, Satan and his followers; thirdly there are allegorical personages, Sin and Death; and lastly humans, Adam and eve. Mark Pattison has rightly said that an enjoyment of Milton’s poetry is the ultimate reward of consummate scholarship. Milton was a very learned poet, and his learning is strewn wide over Paradise Lost. Allusions to classical literature and mythology, to Biblical mythology, and to contemporary literatures of Europe, especially Italian, are abundant and plentiful stumbling blocks in the ways of the readers. The first lines of the first book of the epic has references to â€Å"Oreb† (7), â€Å"That Shepherd (8), â€Å"Siloa’s Brook†, â€Å"Aonian Mount†, etc. proves the fact. Latin constructions, use of words in their original Latin sense, and epigrammatic terseness are other sources of difficulty. That is why the beauty and grandeur of the epic can be enjoyed only after a number of readings. But such readings are fruitful and rewarding. At times the Latin usages give an elusive meaning as in the following passage: â€Å"Soft oppression seis’d My droused sense, untroubl’d though I thought I then was passing to my former state Insensible and forthwith to dissolve. † (VIII, 291-296) More specially the epic similes, more frequent in this epic than in Homer or Virgil, uplift and dilate the imagination, thrill the senses with their range and variety and are a source of great aesthetic pleasure. One of the most noteworthy epic similes from Milton in Paradise Lost is that which deals with the will-o-the-wisp in book IX, Lines 633-42: â€Å"Hope elevates, and joy Brightns his Crest, as when a wandring Fire Compact of unctuous vapor, which the Night  Condenses, and the cold environs round, Kindld through agitation to a Flame, Which oft, they say, some evil Spirit attends Hovering and blazing with delusive Light, Misleads th amazd Night-wanderer from his way To Boggs and Mires, and oft through Pond or Poole, There swallowd up and lost, from succour farr. † (IX, 633-42) Coupled with the sublimity and grandeur of diction, there is sonorous verbal music of Milton. P aradise Lost is written in blank verse, and its handling is superb throughout. Each line consists of five feet and ten syllables, the accent being on the second syllable. Here Milton introduced endless variations in metre, to give music, flexibility and variety to the verse. The use of trochees and spondees and clever manipulation of pauses add to the effect. But the chief peculiarity of Milton’s blank verse is his use of the verse paragraph where the meaning of the line does not end with it but overflows to the next lines. We might have lost faith in Milton’s theology and the story of the fall of man may have been exploded by science, but Paradise Lost will never decay and die. It is an immortal work of art and it will live on by virtue of its manifold poetic beauties.

Surface State in Bi1.5Sb0.5Te1.7Se1.3 Nanoflakes

Surface State in Bi1.5Sb0.5Te1.7Se1.3 Nanoflakes Result of a study on the surface state in Bi1.5Sb0.5Te1.7Se1.3 nanoflakes 4.1 Introduction The recent discovery of topological insulators (TIs) has provided new route for producing low-dimensional relativistic electronic states. The exotic surface states of TIs have attracted the attention of scientists because of their fascinating physical properties and applicability in spintronics and quantum computations [24-28]. The unique surface states were confirmed by angle-resolved photoemission spectroscopy (ARPES) experiments and scanning tunneling microscopy (STM) on Sb2Te3, Bi2Te3, and Bi2Se3 [29-34]. Magnetotransport studies have also provided a clear picture of the topological surface state and the  ° Berry phase shift [35, 36],which gives rise to the immunity of Dirac fermions to localization. Bi2Te3 and Bi2Se3 are suitable candidates for TI studies because of their large energy gaps. Eg is approximately equal to 0.3 eV and 0.17 eV. However, the metallic bulk conduction of natural imperfections, such as vacancies or antisite defects in these materials, makes it difficult to probe surface Dirac fermions. Therefore, a high-insulating bulk state is a prerequisite for transport property studies of TIs. Substantial effort has made it possible to examine both the surface and the bulk channels either through electrical gating [36-42] or substitution doping [12-14, 42]. Recently, it was discovered that Bi2-xSbxTe3-ySey (BSTS) is a high-insulating bulk TI. BSTS exhibits a tetradymite structure, a low carrier concentration (2.3 Ãâ€" 1016 cm3), and a large bulk resistivity (8 ÃŽ © cm) because of the ordered occupation of Te/Se in the quintuple-layer unit [12, 13]. However, a reliable detection of surface quantum oscillations is difficult in BSTS flakes because of the inhomogeneous defect [12] and low surface mobility [40]. Thus, the low mobility in a bulk channel plays a crucial role in probing surface quantum oscillations. In this chapter, we report the observation of surface-dominated transport in the topological insulator BSTS nanoflakes. Shubnikov-de Hass (SdH) oscillations study on the 200-nm BSTS nanoflake indicates that the achievement of surface-dominated transport can be attributed its high surface mobility of 2602 cm2/Vs (top surface), 3657 cm2/Vs (bottom surface), and low bulk mobility of 12 cm2/V s, which is a much lower value than those reported [12-13, 40-41]. Besides, the nontrivial Dirac surface state was further confirmed by the weak anti-localization (WAL) effect and the semiconducting to metallic transport transformation as the thickness of the specimen was reduced to the thin film limit, in which a up to 90% contribution from the surface channel was estimated based on the thickness dependence of the electrical conductance and the result of the SdH oscillations. 4.2 Method BSTS single crystals nominally composed of Bi1.5Sb0.5Te1.7Se1.3 were grown by melting the mixture of Bi (99.999%), Sb (99.999%), Te (99.999%), and Se (99.999%) in sealed evacuated quartz tubes. First the mixture was slowly ramped up to 750  °C at a rate of 100  °C/h and kept at 750  °C for 12 h. It was then furnace cooled to room temperature at a rate of 100  °C/h. The sample was reground and sintered again. The same procedure was repeated three times to ensure sample homogeneity. Finally, the sample was heated to 800  °C for 48 h, then cooled to 500  °C and annealed for 96 h. The crystal structures of the samples were identified using powder X-ray diffraction and refined using the General Structure Analysis System (GSAS) software package equipped with the EXPGUI interface, as shown in Figure 4.1(a). Transport measurements were conducted using a Quantum Design Physical Property Measurement System (PPMS) and six-terminal Hall bar geometric specimens. The nanoflake specimens [Figure 4.1(b)] were mechanically exfoliated and transferred to the Si3N4 (200 nm)/Si substrate. The electrodes of the nanoflake were patterned using standard e-beam lithography and thermal evaporation of Ti/Au. Figure 4.1. (a) GSAS refinement of powder X-ray data of a BSTS crystal. Red circles represent experimental results, the green line represents calculated results, the blue line indicates the difference, and the Bragg peaks of the BSTS are shown by the vertical lines, where Rp, Rwp, and à ¯Ã‚ Ã‚ £2 represent the goodness factors. (b) The SEM image of a BSTS 160-nm nanoflake. 4.3 Results and discussion 4.3.1 Thickness and temperature dependence of resistance The considerable thickness dependence of electrical transport showed a transition from semiconducting to metallic behavior as the bulk content is reduced, as shown in Figure 4.2 (a). For the thick specimens, the thermal activation energies given by the Arrhenius law were 4.3 meV (140 ÃŽ ¼m), 3.5 meV (49 ÃŽ ¼m), and 2.37 meV (7 ÃŽ ¼m). The smaller activation energy of thinner specimens can be explained by the increasing contribution of surface states [12-13, 40-41]. In 140-ÃŽ ¼m BSTS, a significant deviation occurred below 20 K from the fitting to a three-dimensional variable-range hopping model (3D VRH) with Rxx is approximately exp[(T/T0)-1/4] [13], indicating the existence of a parallel metallic conduction of surface states [the inset in Figure 4.2 (a)]. According to Eq. 4.1, the total conductance G ° of a specimen with a thickness t can be formulated as G ° = Gs + à ¯Ã‚ Ã‚ ³bt, (4.1) where Gs is the surface sheet conductance, and ÏÆ'b is the bulk conductivity [38,42]. Gs =36.2 (e2/h) and à ¯Ã‚ Ã‚ ³b = 4.14 (e2/h) ÃŽ ¼m−1, which resulted from the fit of thickness dependence of conductance to Eq. 4.1. For a 200-nm nanoflake at 2 K, up to 90% of the contribution from the surface state was obtained, as shown in Figure 4.2 (b). Figure 4.2. (a) Temperature dependence of resistivity for BSTS specimens with thicknesses of 140 ÃŽ ¼m, 200 nm, 160 nm, and 80 nm. The inset shows the fit of 3D variable-range hopping to the 140-lm specimens. (b) Thickness dependence of sheet conductance; the red line is the fit with G ° = Gs + à ¯Ã‚ Ã‚ ³bt. The inset shows the fitting of the Arrhenius law to the 140-ÃŽ ¼m specimen. 4.3.2 Hall measurements of BSTS To understand the semiconductor-metallic transitions, we focus on the charge transport behavior (Figure 4.3) and temperature dependence Hall measurement results of 160 nm specimen (Figure 4.4). Because of that the thickness seems like to the critical in between semiconductor and metallic transition. In Figure 4.3 (a), we gives three regimes in the temperature profile, one can obtain the nanoflake specimen with 160 nm thick showing metallic behavior which contrasts to its bulk. In the regime I, the bulk conduction dominates, as the temperature decreases the resistance increased which shows a general narrow-gap semiconductor behavior this can be attributed to freezing of the impurity band carrier in the bulk [27]. The regime II reveals a typical metallic behavior signature, the resistance decreases as temperature reduced, this can be explained as reduce phonon scattering and nearly constant carrier density (shown in Figure 4.4 (a)) with a decreasing temperature. In regime III, when the temperature is lower than 10 K, a slightly increases in resistance due to the bulk carriers freeze out [28]. Hall mobility measurements provide more clearly picture to realize the thickness dependence charge transport as shown in Figure 4.4 (b). The reduction in the degree of disorder or impurity of specimens can be obtained in Figure 4.4 (b) that the mobility enhanced as thickness decreased and their different temperature dependence trends. In thinner specimens (160 and 80 nm) the mobility shows monotonically increasing as decreasing temperature, surface dominate transport should play a more important role in this manner. Figure 4.3. Temperature dependence of the normalized resistance of specimens. Figure 4.4 (a) Temperature dependence of the Hall measurement results of 160 nm thick specimen. (b) Thickness dependence of Hall mobility versus temperature curve. 4.3.3 Surface quantum oscillations (Shubnikov-de Haas oscillations) Because successive empting of Landau levels (LLs) provides the nth minima in à ¯Ã†â€™Ã‚ ³Rxx, the relation of the LL index n to the Fermi surface cross-section area AF can be described using the semiclassical Onsager equation: 2 ° (n + à ¯Ã‚ Ã‚ §) = AF Ä § / eB. For the Schrodinger electron case, à ¯Ã‚ Ã‚ § = 0, which results in a zero Berry phase. à ¯Ã‚ Ã‚ § = 1/2 indicates the case of the Dirac fermion of TIs, which results in a  ° Berry phase where the charge carrier is immune to localization. The temperature dependence of resistance for a 200-nm nanoflake shows à ¯Ã†â€™Ã‚ ³Rxx as a function of 1/B after a smoothing background subtraction, as shown in Figure 4.5 (a). Two sets of oscillation periods are marked; one with a black dashed line ([(à ¯Ã†â€™Ã‚ ³(1/B) = 0.041 T-1]) and the other with a blue dashed line (0.022 T-1) for the surfaces of the nanoflake specimen. The multicomponent nature of SdH oscillations originates from the Fermi-level positions of the two surfaces. If SdH oscillations are as a result of the two-dimensional electron gas (2DEG) formed with band bending near the surface, the corresponded carrier density differs in an order of magnitude [35] compared to the Hall measurement result [n3D = 3.5 à ¯Ã¢â‚¬Å¡Ã‚ ´ 101 8cm-3], which is obtained from the fit to low field B ( ±1T) data (Figure 4.5 (b)). Figure 4.5 (c) shows the LL fan diagram plotted in 1/B versus nth oscillation minima in à ¯Ã†â€™Ã‚ ³Rxx. The linear fit of the two-set SdH spectrum yields the intercepts of à ¯Ã‚ Ã‚ § = 0.48  ± 0.3 for Surface 1 and 0.49  ± 0.02 for Surface 2, where à ¯Ã‚ Ã‚ § values are closer to the theoretical value of 0.5 for ideal Dirac fermions. It is assumed that Surface 2 is the top surface because environmental contamination provides effective n-type doping [17] to the sample, which strongly influences the top surface. The specimens were closely stacked on the substrate to prevent the bottom surface from air contamination and electron-beam irradiation. Thus, the second set of SdH oscillations appears in the lower inversed field, shown in Figure 4.5 (a), which was probably from the top surface. In Figure 4.5 (c), the slope of one set of SdH oscillations provides the cross-section area of the Fermi surface [AF = 4.15 Ãâ€" 1017 m-2], and the Fermi wave number was = 0.0363 and the 2D surface carrier density was = 1.05 Ãâ€" 1012 cm-2 for the top surface (Surface 2). The second set of SdH oscillations resulted in AF = 2.32 Ãâ€" 1017 m-2 and = 0.02718 , and 0.58 Ãâ€" 1012 cm-2 for the bottom surface (Surface 1). Figure 4.5 (d) shows the fit of temperature dependence of SdH amplitudes to the Lifshitz-Kosevich (LK) theory [11, 43].The cyclotron mass mc = 0.075 me is the same as that reported [13]. Once mc is known, we can calculate the Fermi velocity and the Fermi level position to be vF = 5.6 Ãâ€" 105 m/s and EF = 134 meV above the Dirac point for the top surface and vF = 4.19 Ãâ€" 105 m/s and EF = 75 meV for the bottom surface. The high Fermi level position of the top surface is consistent with the results of environmental doping mentioned previously. Due to the multiple component nature, the Dingle temperature is difficult to extrapolate from the SdH amplitude; therefore, Eq. 4.2 is used to fit the resistance data to the LK theory , (4.2) where F is the frequency of SdH oscillations extracted from the slopes of Figure 4.5 (c), the thermal factor is , and the Dingle temperature is [11, 43]. The solid red line in Figure 4.5 (e) shows the optimal fitted results of à ¯Ã‚ Ã‚ § = 0.5 and à ¯Ã‚ Ã‚ ´ = 1.11 Ãâ€" 10-13 s for the top surface, and à ¯Ã‚ Ã‚ § = 0.35 and à ¯Ã‚ Ã‚ ´ = 1.56 Ãâ€" 10-13 s for the bottom surface. The fitted à ¯Ã‚ Ã‚ § values are close to theoretical value of 0.5 for ideal Dirac fermions. According to the Dingle analysis, the scattering time is approximately two to three times larger than that of the bulk BSTS [13]. Mobility is a measure of scattering time; therefore, it is possible to calculate the surface mobility ÃŽ ¼s = 2602 cm2V-1s-1 and the mean free path = 62 nm for the top surface, and ÃŽ ¼s = 3657 cm2V-1s-1 and = 65 nm for the bottom surface. The surface mobility enhancement is consistent with the longer mean free path of the nontrivial topological Dirac state. The surface contribution to the total conductance (Gs/Gtot = 84.8%) was consistent with the results obtained from the thickness dependence of conductance. Take the sheet carrier density into account, n = ns + nb t [44]. The mobility of the bulk channel was 12 cm2/Vs, which is close to the total Hall mobility of the 140-ÃŽ ¼m thick BSTS specimen, 13 cm2/Vs. The low Hall mobility of bulk carriers causes less interference with the surface Dirac fermions; thus, the enhancement of the surface contribution and quantum oscillations was detected in the specimens used in this study. Figure 4.5. (a) Temperature dependence of resistance. à ¯Ã†â€™Ã‚ ³Rxx is function of 1/B. n = 4, 5, and 6 are the LLs of the bottom surface; n = 6, 7, 8, and 9 are the LLs of the top surface of the 200-nm nanoflake. (b) Hall resistance versus magnetic field. The red dashed line is extended from the low B ( ±1T) fit. The inset shows the Fermi level positions of the top and bottom surfaces, respectively.

(d) The fit of temperature dependence of the SdH oscillation amplitude to the LK theory. (e) à ¯Ã†â€™Ã‚ ³R versus 1/B. The black curve is the experimental data, and the red curve is the fit to LK theory. 4.3.4 Weak anti-localization effect In addition to SdH oscillations, the helical surface state was further probed using the WAL effect on the 200-nm BSTS. The WAL effect in TIs originated from the  ° Berry phase, in which the probability of backscattering was suppressed as a result of the destructive interference of time-reversed paths. The angle field dependence magnetoconductance analysis is shown in Figure 4.6 (a). The sharp cusps of the magnetoconductance in the lower field region are features of WAL. The 2D nature of Dirac fermions associated with the  ° Berry phase, which is dependent only on the perpendicular component of the applying field, was obtained by subtracting the background from the 3D bulk WAL contribution, ΔGxx(ÃŽ ¸,B) = Gxx(ÃŽ ¸,B) Gxx(90 °,B) (5), as shown in Figure 4.6 (b). Figure 4.6 (b) shows that low-angle data merge into a single universal curve [15]. The Hikami-Larkin-Nagaoka (HLN) [15] model is used to calculate sheet conductance [27], as given in Eq. (3): , (4.3) where Gxx is sheet conductance, is the phase coherent length, and is the digamma function. The value for à ¯Ã‚ Ã‚ ¡ (-0.96) and (121 nm) were obtained for the 200-nm nanoflake. For the WAL effect in TIs, the prefactor à ¯Ã‚ Ã‚ ¡ was equal to -0.5 for a single surface state [40]. The complicacies of topological surface states resulted in an experimental value à ¯Ã‚ Ã‚ ¡ between -0.4 to -1.5 [38, 40]. In this study, the value à ¯Ã‚ Ã‚ ¡ = -0.96 indicated the existence of two surface states. Figure 4.6. (a) The angle field dependence magnetoconductance of the 200-nm nanoflake.

Low-angle data merge into a single curve (the green dashed line) fitted using the HLN model. 4.4 Conclusion In this study, dominated surface transport was observed in BSTS nanoflakes. The thickness dependence electrical transport and the SdH oscillations illustrated that the surface states in the 200-nm BSTS nanoflake contribute to nearly 90 % of the conductance. The achievement of the surface-dominated transport is mainly attributed to the high surface mobility relative to the bulk channel. The observation of SdH oscillations provides clear evidence of surface Dirac fermions. Surface-dominated transport was further confirmed by the WAL effect showing 2D nature of helical Dirac surface states. Moreover, electrical transport transforms from semiconducting to metallic behavior, and mobility was enhanced when the thickness decreased, indicating that surface states plays a crucial role in the thin film limit. The high-insulating bulk state in BSTS nanoflakes provides opportunities for future quantum computation and spintronics applications.

Mental State Examination (MSE) Case Study

Mental State Examination (MSE) Case Study Lachlan Donnet-Jones Giving examples from the case study, how would you describe Amanda’s behaviour and appearance as set out in a Mental State Examination (MSE)? A Mental State Examination (MSE) is defined as â€Å"[a] medical examination comprising the systematic evaluation of the mental status of the patient† (Dorland, 2011). A MSE evaluates many characteristics of a patient including appearance, psychomotor behaviour, speech, thinking and perception, emotional state including affect and mood, insight and judgment, intelligence, sensorium, attention and concentration, and memory (Dorland, 2011). The initial segments evaluated during a MSE are appearance and behaviour. It is important to note the patient’s appearance as this can provide useful information into the level of self-care, daily living skills and lifestyle of the patient. Behaviour is important to record as it can provide much insight into the patient’s emotional state and attitude. A MSE is an important process in determining a patient’s capacity to make [or not] independent health care decisions and provide the necessary support to better the patients welfare (Volicer, 2011). Appearance: The initial insight into Amanda’s appearance occurs as the paramedic crew arrive, finding her ‘sitting upright, looking dazed and anxious with shortness of breath’. It is apparent that Amanda appears distressed, confused and anxious enough to cause her to become dyspnoeic (shortness of breath) (Shiber and Santana, 2006). Amanda is a young woman with dyed, untidy and matted hair who presents with a poor level of personal hygiene and self-care. Amanda has many facial piercings, her pupils are extremely dilated and her arms are covered in sores. Subsequent to Amanda’s arrival at the emergency department (ED) she appears very tense and her facial expressions change rapidly from smiling to terrified. Amanda’s mother re-counted that Amanda ‘comes home dishevelled and dirty’, and that she has ‘lost a lot of weight’. Behaviour: Following the handover to the clinician at the hospital, it is observed that Amanda appears to be suffering a level of psychomotor agitation as she is ‘very tense†¦ pacing up and down the corridor wringing her hands’. Amanda appears unable to focus, demonstrated by abnormal and erratic eye movements, ‘her eyes stare intensely either into the ceiling above or at staff members’. Amanda appears to be suspicious of and distrust staff members as she distances herself as much as possible from any physical contact and enters the room ‘like she’s about to enter a trap’. During the interview Amanda screams ‘They’re everywhere. Everywhere†¦under my skin!’. Amanda appears to be experiencing tactile hallucinations, she believes there is something beneath her skin, when there is not. Amanda also appears to be experiencing auditory sensation (voices) without an authentic (real) stimulus i.e. auditory hallucinations. This is seen as she looks up at the ceiling yelling ‘Shut up shut up shut up!!!!!! then distressed, proceeds to scream and hold her ears as if to block a loud noise’ and furthermore, ‘Why am I here!!! You won’t tell her anything will you?’. Amanda talks about ‘her’, which may be referring to her mother, but it may also be referring to someone else. Define cognition and then briefly discuss how we might interpret how both Amanda’s thought content and thought form are disturbed? Cognition is defined as ‘the mental processes by which a person acquires knowledge.’ Among these are reasoning, creative actions and solving problems (Marcovitch, 2009). Cognition is an essential in determining what we think and how we think. In an MSE, thought form and thought content are used to gain an understanding of the patients thinking, specifically how they think (form) and what they are thinking of (content) (Trzepacz and Baker, 1993). Thought form is the quantity, rate, tempo and logical coherence of a person’s thoughts. The thought form may include highly irrelevant comments, frequent changes in topic and pressured or halted speech (Kaufman and Zun, 1995). In contrast, thought content refers to selective attention (focus on a selective topic), preoccupation or exaggerated concern (obsessions, compulsions and hypochondria) and distorting or ignoring reality (illusions, hallucinations and delusions) (Trzepacz and Baker, 1993). During Amanda’s interview a number of sentences allude to disturbed thought content such as ‘You know don’t you? You know it’s in my veins!’ and ‘Every one of us is falling – the whole planet is falling!’. Amanda’s exclamations are examples of unsubstantiated thinking and are possibly part of an illusion. The thought form of such exclamations is disorganised, hastily changing from one topic to another, â€Å"they’re in my veins†, â€Å"the whole planet is falling!†, ‘Shut up shut up shut up!!† and ‘Forgive me! Forgive me!’. While the specific idea changes there is a recurrent theme to Amanda’s thought content, disastrous, guilty and fearful situations that are beyond her control. It is evident based on the irrelevant topics and unsubstantiated thinking observed in Amanda’s speech that her thought content is disturbed. Amanda’s thought form also appears distu rbed demonstrated by the ‘flight of idea’s’ she experiences and her inability to focus on a relevant topic within the context of the situation (Trzepacz and Baker, 1993). Briefly explain the differences between hearing and listening. Choose two skills of listening and discuss how you would use these skills to effectively communicate with Amanda. What are some of the barriers you might face in the process? Listening is defined as ‘a complex process that encompasses the skills of reception, perception and interpretation of input.’ (Stein-Parbury, 2013). As opposed to hearing, listening is consciously chosen, one must be paying ‘active attention to what is being said’ (Stein-Parbury, 2013). Additionally there are two terms for listening, active and passive. Active listening is effective listening. It requires concentration to process words into meaning which in turn leads to learning. Hearing, or passive listening, is one of the five senses a human possesses, it is simply perceiving sound (vibrations) via the ear. Hearing alone is a subconscious process and happens automatically. A nursing research paper provides a succinct definition of the difference between hearing and listening. Hearing is ‘being there’ for patients whereas listening is ‘being with’ patients (Fredriksson, 1999). In order to conduct effective active listening and exchange information with patients a clinician needs to possess the required listening skills. There are five categories of listening skills; perceiving; interpreting; recalling; and attending and observing, which will be discussed in relation to Amanda’s case (Stein-Parbury, 2013). Observation from the clinician is important in Amanda’s case as much information can be learnt simply from observing Amanda’s behaviour. Observing involves paying careful attention to what is expressed and how it is expressed (Stein-Parbury, 2013). Non-verbal cues such as facial expression, eye contact, body posture and movements ‘[convey] emotional and relational information [Henry et al. 2012] that can inform the clinician of Amanda’s feelings and emotional state. The clinician notices that Amanda is ‘wringing her hands from time to time’, which may suggest she is feeling nervous and anxious. This is an example of observation, by paying careful attention to Amanda’s non-verbal cues (hand wringing) the clinician has an increased awareness of Amanda’s feelings. Amanda’s eyes ‘stare intensely either into the ceiling above or at staff members’, the clinician may interpret this as a sign of distrust and suspicion. Using this knowledge the clinician recognises the absence of trust and can address this in his response to build rapport. Although observing and interpreting the patient’s non-verbal cues is important, it is equally important for the clinician to provide their own non-verbal cues for the patient to interpret. This is referred to as attending. A common mnemonic used for this is SOLER (Sit squarely, Open posture, Lean forward, Eye-contact, Relaxed) (Egan, 2002). Encouragement such as quiet murmuring (e.g. â€Å"Mmm†) and head nodding is also used to show attentiveness and openness, allowing the patient to feel understood. Despite many methods of encouragement and understanding the clinician may still find barriers with particular patients. In Amanda’s case some barriers may include Amanda’s apparent lack of awareness to her environment, she may be unable to listen or acknowledge the clinician, such as when she is staring at the ceiling. Amanda’s hallucinations can potentially disrupt or prevent any congruent conversation and distort her responses. Observation and attending are important skills in listening as they are ‘fundamental in establishing effective relationships’ (Stein-Parbury, 2013). Using listening skills to develop a comprehensive understanding of Amanda’s situation the clinician can respond accordingly in a manner that matches Amanda’s needs. Define therapeutic communication. Using case study examples, explain the difficulties involved in communication when managing a complex scene that includes an anxious patient who presents in the emergency department with a distressed and demanding relative. Hungerford (2011) defines therapeutic communication as ‘a communication technique utilised by a health professional to engage with a person and enable them to achieve personal change’. It is essentially the face to face communication between clinician and patient that aims to enable positive change in the patient. An anxious patient such as Amanda can be difficult to manage, especially in the presence of bystanders or relatives who are distressed, in Amanda’s case it is her mother. While Amanda’s mother may mean well, she is most likely contributing to Amanda’s anxiety. Rather than aiding health professionals she is hindering their ability to reduce Amanda’s anxiety as she ‘[is] constantly obstructing and getting in their way causing interruptions’. In addition to increasing Amanda’s anxiety, health professional’s attention may be taken away from Amanda and focused on calming the mother down. This has a negative impa ct of the patient’s well-being, increasing the time it takes to de-escalate the situation and decrease the patient’s anxiety. Amanda’s mother’s constant interruptions have a negative impact of the patient’s well-being. For example, ‘She is not right; she is really unwell’ as heard from Amanda’s perspective is escalating the situation, making Amanda feel worse than she has too and increasing her anxiety. A potential method to avoid relatives increasing patient anxiety is to separate them. The paramedics separate them during transport, taking Amanda in the ambulance where she can receive further care that is needed, and Amanda’s mother via police. At the ED Amanda’s mother continues to interrupt clinicians. To remove the potential of increasing Amanda’s distress, the clinician interviews Amanda alone. Although Amanda’s mum provided important information it was beneficial to interview Amanda alone. In a situation where a relative is distressed and interferes with treatment it is most appropriate to kindly separate them from the patient, take them to another area where they can calm down and perhaps have a drink or some food. What are the key components of an effective handover between health professionals from different disciplines? Discuss the important considerations of patient handover in regards to objective information and confidentiality (8). A clinical handover is ‘the transfer of professional responsibility and accountability for some or all aspects of care for a patient, or group of patients, to another person or professional group on a temporary or permanent basis’ (National Patient Safety Agency, 2014). The aim of the handover is to establish effective communication of clinical information during patient transfer from the care of one health professional to another. There are numerous steps or processes involved in an effective handover. First, the clinician sending information needs to show strong leadership. Second, any members of the medical team involved in the care of the patient prior to or subsequent to the handover should have an active role in the handover. Third, a multifaceted quantity of information involving the patients past, current and future care should be provided. Finally, the fourth step is to ensure patients that are not stable are quickly reviewed, further care is planned and the tasks are prioritised appropriately (AMA, 2006). Patients expect that confidentiality is respected and personal information is treated with utmost care. Confidentiality is an important legal obligation of health professionals. Delicate and sensitive information regarding patient care should not be discussed in potentially compromised areas, ideally in private quarters away from the public. A final factor to consider during patient handover is the level of objective information. Objective information is fact-based, measurable and observable, as opposed to subjective information which is based on personal opinions, interpretations and judgement (Hjà ¸rland, 2007). Health professionals are required to avoid relaying information that is judgemental, opinion and subjective as this form of information can lead to misinformed health professionals which consequently creates poor or inappropriate patient care (Hemmings and Brown, 2009).

Teaching Philosophy :: Education Teachers Classroom Essays

Teaching Philosophy Teachers are the sculptors of every child’s future. No other job comes with the satisfaction of knowing that you have made at least the slightest difference in a child’s life. Little things that you say and do will always be remembered. Not only will you be a teacher but you will also play the role as, a friend, mentor, hero, and many others. As a teacher I plan to run my classroom with rules and consequences, but my students will realize that they are treated fairly. They will have a voice and say so concerning what goes on in the classroom. Seating arrangements will depend on classroom instructional activities. There will be lots of group activities, since most kindergarteners aren’t used to being around children their own age. The room will be bright and very colorful to keep their senses alert. My bulletin boards will display the calendar, colors, numbers, and the alphabet. They will include people from all cultures on them. I will have learning centers around the room that the students will be able to go to in their free time. These centers will teach the students to tie their shoes, button their clothes, cut out shapes, color in the lines, and other supplementary skills. My classroom will be run in a democratic fashion, which is pragmatism. The students will have lots of say so over the rules and the way the classroom is run. It will be child centered since the students will be the most important part of the classroom. They will have a voice and say so concerning what goes on in the classro om. These are examples of how I will use the existentialism philosophy. I will be a guide in the learning process of my students. I would establish a non-authoritarian classroom. I want my students to see me as their instructor, not their boss or authority figure. I will run a facilitating classroom with circle seating arrangements, student centered activities, problem solving, and reciprocal teaching. I feel as if I am a pragmatist and I will use the theory or progressivism to run my classroom.

The Interesting Narrative of the Life of Olauda Equiano Essay -- Slave

The Interesting Narrative of the Life of Olauda Equiano The narrative by Olaudah Equiano gives an interesting perspective of slavery both within and outside of Africa in the eighteenth century. From these writings we can gain insight into the religion and customs of an African culture. We can also see how developed the system of trade was within Africa, and worldwide by this time. Finally, we hear an insider's view on being enslaved, how slaves were treated in Africa, and what the treatment of African slaves was like at the hands of the Europeans. Olaudah spends a good part of the narrative acquainting the reader with the customs of his people. He describes the importance of hygiene to his people. Their overall health and vigor was helped by their penchant for cleanliness, and it makes them seem more "advanced." This is an interesting development considering the problems that a lack of hygiene can lead to. His description of a wedding also seems very modern, but the importance of dance in the festivities shows another facet of Olaudah's people. The dance defined the different groups within their village. First, and most important, were the married men, followed by married women, single men, and lastly unmarried women. The groups also used the dance to relate stories or tell events that were important to them. This practice probably also strengthened the bonds within the groups. Olaudah also wrote about the division of chores within his village. The women were responsible for the spinning and weaving, and the men took care of the building. It is interesting to note the similarity of their dress, and the fact that both men and women joined in battle when the village was at war. They did not, however, sleep in the same ... ...rall his treatment was very good; one master even carried him when he was too tired to walk! In sharp contrast to that treatment was the treatment he describes at the hands of Europeans. In his own words, they treat him with "brutal cruelty." They seem to have a callous disregard for their captives, and treat them like vicious animals. From his description of the voyage, how the prisoners were stowed, and the way they were treated we gain proof that these Europeans felt the Africans were less than human. Overall, the narrative by Olaudah Equiano is a great first-hand look at the lives of some of the millions of people who were transported to other countries. They became a commodity sought after as laborers by a people they had never seen. The narrative also shows the folly of the European belief that the Africans were savages and could be treated accordingly.

Pesticides Essay -- Environment, Pollution

People have been abusing the environment for too long. Americans should not use chemicals without researching and considering serious consequences. Rachel Carson, an aquatic biologist who helped shape the U.S. Environmental Protection Agency, wrote an article about the damage chemicals are having on the earth. She presented a great point that most damage Americans are causing to the earth cannot be reversed. These chemicals are left in the air or in the ground for generations (Carson 50). Americans should use environmentally friendly pesticides to reduce pollution and improve human and animal health. One of the main reasons to use environmentally friendly pesticides is to reduce pollution. In an article from National Wildlife, it was found that surface and groundwater pollution is the biggest â€Å"uncontrolled† threat to American water today. This is caused when rain washes the chemicals from pesticides in into streams, lakes, and other bodies of water (Miller, par. 5). It can be very hard to monitor this issue because it is difficult to decide which farmer is using too much or even misusing pesticides (Miller, par.5). One way to reduce pollution from pesticides is to cut back on the amount of pesticides used. Farmers in Iowa were encouraged to reduce the use of pesticides and fertilizers on their crops to help stop polluting the groundwater and runoffs. The farmers were over-using fertilizers and pesticides because they were not taking into consideration the fertilizers that were already in the ground from past years. Since the project began, there has been a dec line in nitrate levels in groundwater (Miller, par. 16). If all farmers would adopt this new way of thinking, the water contamination problem would deteriora... ...pesticides that will harm the earth nor eating any pesticides. Like Rachel Carson, all Americans should be very concerned about the impact pesticides are having on the environment and all living creatures. In her conclusion to The Obligation to Endure she says, â€Å"I contend that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife and man himself. Further generations are unlikely to condone our lack of prudent concern for the integrity of the natural world that supports all life† (Carson 54). She, as well as many others, recognizes a major issue in current actions with pesticides but is hopeful for the future. A little change in each person can achieve great results. To reduce pollution and improve the health of humans and animals, Americans should only use environmental friendly pesticides.

Dramatic devices in “Romeo and Juliet” Essay

In this essay I will explain and show how Shakespeare makes the audience feel increasingly sympathetic towards Juliet in Act 3, Scene 5 of Romeo and Juliet. This play is one of the most well known love stories in history. Shakespeare’s uses of dramatic devices cleverly create twists and tension throughout the entire play. Towards this climax Shakespeare uses the following events that build up to the scene. These are traditional/historical aspects of marriage and family loyalty; cross purposes (Romeos exit) dramatic irony and use of language. Before this scene there are several things that make us feel sympathetic. Juliet is 13 and is in the midst of all the action. She is helpless and Is unable to cope with it. This puts her under a lot of pressure. This makes us feel more sympathy as she has no comfort from her mother or farther Her relationship with her mother is very formal, she does this by addressing her mother â€Å"mistress† or lady. This shows her relationship with her mother is unlike a normal relationship, but more like a respectful relationships, this makes us feel sympathetic towards her as she cannot explain or tell her things. Juliet’s relationship with her nurse is more like a mother daughter relationship. Another reason to feel sympathetic towards Juliet is that her cousin Tybalt has been killed by her husband Romeo. This is a blow to Juliet as she slept with Romeo. I feel that this is a big factor to the build up towards act 3 scene 5. The traditional and historical aspects of this marriage and family loyalty also play a large role in the build up towards the climax. Juliet must abide by her parents rules in order to say in the house. This brings us onto the marriage, normally in this era in time, rich families arrange there children’s marriage so they can have more land and wealth. Juliet breaks this rule and marries Romeo. This makes us feel sympathetic as she has to hide the fact she has feelings towards Romeo. Just before this scene Romeo leaves for Verona; this makes us feel even more sympathetic towards her as she has lost her husband and has no idea of the day of his return. Shakespeare makes us feel sympathetic in this scene by making Juliet use ambiguous language like â€Å"Madam, I am not well.† This has two meanings – she’s either physically ill or love-sick (she’s missing Romeo). This makes us sympathetic towards her as being ill is generally not a pleasant thing to experience. Shakespeare makes us feel increasingly sympathetic in this scene as Lady Capulet says â€Å"Evermore weeping for your cousin’s death?† This shows us Juliet is misunderstood by her family – this plays a part in making us feel sorry for her along with the fact that she has just lost her cousin brutally. In Act 3 Scene 5, we feel sorry for Juliet as she says â€Å"†¦Till I behold him -dead- is my poor heart.† The word ‘poor’ makes the readers obliged to feel sorry for her as it makes us feel she is suffering. This phrase is ambiguous – it can mean she will never be satisfied until her holds the killer of her cousin dead, or will never be satisfied because her ‘poor’ heart is dead. We feel sympathetic as she is being continually misunderstood – she does not want to hold the killer of her cousin dead, but her poor heart is dead because she misses Romeo. When Lady Capulet breaks the news of Juliet’s marriage to Paris, and Juliet rejects this, her mother passes her onto her father – like a burden or a ‘baggage’. We feel sympathy as she is not receiving love from her parents like we’d expect. We feel that she is neglected, unwanted and unloved. When Capulet is fuming over Juliet’s refusal to marry the ‘young and noble’ Paris, he calls her a tallow face and other words meaning pale and tells her that if she does not go to church on Thursday morning to marry Paris, he will drag her to church, similar to how a criminal would be dragged through the streets for doing a crime. He also calls her a ‘green-sickness’, a ‘tallow-face’ and ‘baggage’. This makes us very sympathetic towards her as we don’t expect a father to drag his own daughter through the streets like a prisoner, and to call her spiteful names. Near to the end, the Nurse changes her mind and advises Juliet to marry Paris; â€Å"I think it best you married†¦O, he’s a lovely gentleman!† Juliet feels betrayed and feels like the Nurse is a traitor. This action from the Nurse makes Juliet feel very alone. We sympathise with her as we feel sorry for her being all alone, we want to do something but we are powerless. Overall I feel that this scene gives most impact and makes us make  sympathetic towards Juliet’s most in the entire play due to its twists, it is also the epicenter of the play as it gives most effects. The scene was shocking enough with Juliet being attacked by her father but when her nurse turned on her, this was the turning point in the entire play.
