In the next section, the researcher will describe the theoretical model of e-payment system in order to prepare the background of the proposed recommendations. Three different e-payment systems will be proposed for Book Bunker and security suggestion will also be provided at the end of the report. E- Commerce and E-Payment Systems According to Khosrow-Pour (2008), e-commerce sites help users to buy and sell products and merchandises through online platform and internet communication. When product purchase and sell is being done online then it would be unfeasible to connect manual cash payment with the virtual system due to three reasons, 1- lack of synchronization between manual and online system, 2- lack of symmetry in the information processing and 3- synchronization might decrease the speed of processing (Khosrow-Pour, 2008). H ence, it can be said that absence of e-payment system might create problem for users of the system to pay cash in the virtual environment of e-commerce. Heng (2004) reported that before the arrival of e-payment system, e-commerce companies introduced various e-cash systems such as â€Å"Millicent†, â€Å"Digicash†, and â€Å"PayBox† etc as the predecessor of e-payment system but this earlier version of e-payment systems failed to provide the security and efficiency of transactions. Due to such inefficiency of previous e-payment system, customers shifted to online transaction via credit/debit cards payment or cash payment. According to Abrazhevich (2004), consumers also check for the security settings in the e-payment system and often stop using the e-payment system if the service vendor has

Internal Analysis as a part of strategic planning process of WRSX Assignment

Internal Analysis as a part of strategic planning process of WRSX - Assignment Example Strategic planning is a means of planning at present about the desired future of the company using the knowledge and information about the company today (Special Libraries Association, 2001, p.1). WRSX is a global advertising company, which has been successfully delivering good fortunes in the advertising industry for the past 8 years. Until recently, for about a year, the company had been underperforming below what it is capable of. Failure in strategic management is the primary reason behind this situation. A well-defined, effective strategic plan is the key to success of the company in the near future. This study shows the benefits involved in including internal analysis as a part of the strategic management process and how it can bring WRSX in the right track towards its sustainability and success, in this changing world. Typically, a strategic management process consists of four broad areas. They are: Environmental Scanning, Strategy Formulation, Evaluation and Control (Akhafaji , 2003, p. 6). All these four components are inter-related to each other. Effective strategic planning helps the company to remain focused and achieve the future goals and objectives successfully. Basically a strategic planning process has four main purposes.... The Resource Based View (RBV) approach to strategy management is a tool to identify the potential resources of a firm which can be utilized to achieve competitive advantage and can result in strong performance of the company in future (Barney, J & Penrose, E, 2011). Short-term competitive advantage created from use of available resources of WRSX productively can lead WRSX to sustaining that competitive advantage for a long term if these resources are not imitable or substitutable easily. WRSX needs to develop its resources into core competencies to create competitive advantage. For this VRIN model can be utilized. This model includes the following five attributes of resources: 1) Valuable, meaning the resources must be valuable to the company in creating the strategy, 2) Rare, meaning the resources must be scarcely available to others, in creating value to the company, 3) In-imitable, meaning it cannot be easily imitated, and 4) Non-substitutable, meaning that availability of substit utes are rare (Rothaermel, 2008, p.208-209). WRSX has always been known for creativity and innovation. These are the two key attributes which is very much valuable to the company. These can neither be imitated nor substituted because creations and innovations of WRSX are its own and developed by WRSX only. WRSX enjoys a core competency in developing creativity and is an absolute necessity for an advertising agency like WRSX to satisfy its customer requirements. This helps WRSX attaining competitive advantage over its rivals and must build on it and work for more and more creations and innovations and encourage it at all levels of the company. Development of strategic capabilities can also be a key to the success WRSX. The six

Cognitiveâ€behavioural Syndromes of Neglect and Anosognosia

Cognitive–behavioural Syndromes of Neglect and Anosognosia Considering the neuropsychological diseases discussed during the course, critically compare and discuss theoretical interpretations of at least two syndromes Consciousness is one of the most interesting phenomena of the human mind. Consciousness refers to the integration of the cognitive experiences about self and the external environment (Orfei et al., 2007). However, when this psychological function is damaged, it may lead to dysfunctions in the attention and awareness of personal identity. The focus of the following essay is to provide insight into why the cognitive–behavioural syndromes of neglect and anosognosia for hemiplegia that occur following right hemisphere stroke develop, and to evaluate to what extent this is true, taking into consideration their theoretical interpretations. Anosognosia has been defined by Babinsky (1914) as an impairment leading to unawareness of neurological and cognitive deficits following a brain injury. Individuals who suffer from anosognosia present with motor impairments which lead to gait and self-care deficits and are unaware of their impairments in functioning (Kortte Hillis, 2010). The syndrome of anosognosia often co-occurs with visuo-spacial neglect (Prigatano et al., 2011). Heilman, Watson and Valenstein (1994) defined neglect as a deterioration in attention towards or in response to a stimuli, which is not attributable to a motor or sensory impairment. Neglect is presented as a spectrum, with a variety of forms based on the regions of the lesion, the mode of outputs, reference frame and the sensory modality (Hillis Caramazza, 1995). Alongside their co-occurrence, anosognosia and neglect also overlap in terms of lesion sites, to be more specific, the right temporo-parietal junction, the superior and middle temporal gyri and the right insula (Beschin, Cocchini, Allen Della Sala, 2012). The lesion in the right temporo-parietal junction is extremely important in mechanisms of selective attention. More recent neuroimaging studies have recommended that parts of the parietal and temporal cortex are creating a supramodal structure that interposes goal-directed attention in multiple sensory modalities (Chambers, Stokes Mattingley, 2004). Furthermore, neuroimaging studies show that the insula is very important in self-awareness and in one’s convictions about the functioning of their body parts (Karnath, Baier Nagele, 2005). Taking these in consideration, a lesion in these areas will lead to a dysfunction in directing attention towards a specific stimulus and about their beliefs of body parts functioning, therefore affecting the motor system. The two theoretical interpretations that provide a link between anosognosia and neglect, taking in consideration the dysfunctions presented earlier, are the attentional interpretation model for neglect and the feed-forward model for anosognosia. The attentional interpretation model is a model proposed by Heilman et al. (1993) which states that each hemisphere is provided with its own attentional neurological system, with the attentional system in the right hemisphere directing attention towards both sides of the visual field, whereas the attentional system in the left hemisphere directing attention only towards the right visual field. Therefore, if there is a damage to the left hemisphere, there won’t be a severe right neglect, whereas if there is a lesion to the right hemisphere, the patient will be unable to direct his/hers attention to the left visual field (Bisiach et al., 1998). Corbetta et al. (1993) conducted a PET study on 24 healthy volunteers in order to identify what are the neural systems involved in changing spatial attention towards a visual stimulus in the right or left visual field. Results showed that the right parietal cortex was activated when the participant was required to shift their attention in each visual field, whereas the left parietal lobe was active only when the participants had to change their attention to the right visual field. These finding suggest that the parietal and frontal regions control different aspects of special selection and also support the model proposed by Heilman et al. (1993). However, the attentional interpretation model cannot account for the dysfunctions in the motor system on its own. Therefore, we have to also take in consideration the attentional-arousal hypothesis and the directional hypokenisia. The attentional-arousal hypothesis suggests that neglect is predominantly a form of inattention emerging from the failure of triggering arousal that is needed to activate the neuronal systems necessary for spatial attention (Heilman Valenstien, 1972; Watson et al., 1973, 1974). Furthermore, the attentional hypothesis appears to be in close connection with the motor intention, since when one is directing his/hers attention towards a specific location, one is also ready to perform an action in that direction (Heilman Valenstien, 2003). Directional hypokenisia suggests that patients who suffer from neglect are reluctant in initiating movements towards the contralesional side. Moreover, even when patients are directing attention towards the neglected side and have imposed on them a strategy, their performance not only remained abnormal, but it doesn’t improve (Heilman Valenstien, 1979). In a study conducted by Heilman and Valenties (1979), six patients with neglect were asked to identify a letter that was presented either to the left or right at the end of a line, before bisecting it. The task included lines that were placed at either the left of the body midline, the right, or the centre. Results showed that participants performed significantly better when the line was placed to the right side of the body rather than the left side. These results suggest that the neglect syndrome is a defect in the orienting response. Heilman and Valenstien (1979) suggested that this response appears in anticipation of an action, using the increased arousal to lower the sensory threshold. Therefore, lesions inducing neglect are affecting the arousal (as previously mentioned via the attentional-arousal hypothesis), leading to the inability of the hemisphere to prepare for the action. Based on the same dysfunction of the computational model of motor control is the feed-forward model for anosognosia. More recent theories established on the recent computational models of motor control proposed by Frith et al. (2000), suggest that anosognosia results from an abnormality in motor planning. This theory suggests that, under normal circumstances, in order to develop the intention to move, â€Å"forward models† are being used in order to generate accurate indicators about the approaching sensory feedback. However, if an intended movement is not executed as planned, than a comparator will detect a discrepancy between what it was predicted and the absence of sensory feedback. Therefore, this error can be used to inform the motor system of a malfunction. Furthermore, Heilman and colleagues (1998) proposed that anosognosia is a ‘motor intentional deficit’ which appears from a failure to form motor intentions. Therefore, if the development of an intention t o move is deficient, then the comparator doesn’t receive any instructions about the outline of the movement and the patient considers that the movement has been executed, although no movement has taken place (Gold et. al, 1994). Fotopoulou et al. (2008) conducted a study in which they investigated the role of motor intention in anosognosic patients compared to non-anosognosic patients by detecting whether the anosognosic patients were able to identify the presence or absence of movement focusing only in the visual evidence. False visual feedback of movement in the left paralysed arm was used on four hemiplegic with and four without anosognosic patients. This false visual feedback was delivered using a prosthetic rubber hand. Results showed that patients with anosognosia were more likely than patients without anosognosia to ignore the visual feedback and believe that they moved they hand if there was an intention to move the hand (in the self-generated condition) than when the experimenter moved the rubber hand or when there was no movement. These results support that anosognosia reflects a dominance of motor intention prior to action over the sensory information received after the movement was made (Fotopoul ou et al., 2008). Although the studies presented above do provide a lot of insight in the computational model of awareness and provide an explanation of why these disorders have symptoms such as dysfunctions in directing attention towards a specific stimulus and also about their beliefs of body parts functioning, there are a few limitations to whether these theoretical interpretations can account by their one for the two syndromes. Firstly, although they may co-occur, anosognosia and neglect have also been observed separately. Cocchini, et al. (2009) investigated whether anosognosic patients present with unawareness in a group of 42 left hemisphere damaged patients, using a structured interview and the Visual-Analogue Test for Anosognosia for Motor Impairment (Della Sala, Cocchini, Beschin Cameron, in press). Their results showed that eight anosognosic patients and another twelve patients who were aware of their motor impairments didn’t showed signs of neglect. These results confirm that anosognosia couldn’t be thought of always co-occurring with neglect. Secondly, these results also suggest that there is a double dissociation between anosognosia and neglect (Bisiach et al., 1986). Dauriac-Le Masson et al. (2002) investigated this double dissociation by looking at two patients with a subacute right hemisphere stroke. Their investigation revealed that one of the patients suffered from a severe left hemiplegia which was associated with unilateral neglect and he showed signs of being aware of his motor impairment, whereas the second patient showed a severe anosognosia for hemiplegia, therefore with unawareness towards his motor impairment. These results suggest that although these two syndromes co-occur, they may rely on independent mechanisms because of their double dissociation. And lastly, both anosognosia and neglect are multifaceted processes (Marcel et al., 2004) and only the dysfunction in the computational model of motor control cannot account for all the symptoms of these two syndromes. To be more specific, even when patients who suffer from neglect and anosognosia are aware of their deficits, they still deny them. House and Hodges (1988) detail the case of an 89-year-old woman who suffered left-side paralysis after a right-hemisphere stroke. Although the experimenters demonstrated that her left arm was completely paralysed and her leg nearly paralysed, she failed to understand the severity of her condition and believed that she could still look after herself and walk, although she was in a wheelchair. Furthermore, Marcel et al. (2004) also described the case of several patients who although they were aware of their paralysed limbs, they still overestimated their abilities and believed they can perform bi-manual activities such as clapping their hands or tying a knot. These patients provide examples of another theory of anosognosia, the motivational theory which the patient denies his/hers deficit in order to maintain unharmed his/hers psychological balance (Weinstein Kahn, 1955; Weinstein, 1991). In conclusion, the focus of the essay was to provide insight into why the cognitive–behavioural syndromes of neglect and anosognosia for hemiplegia occur, and to evaluate to what extent this was true, by paying attention to their theoretical interpretations. As stated before, due to the lesions to the tempo-parietal region, the gyrus and insula there are dysfunctions in attention and beliefs about body parts functionality. The attentional intention model for neglect (together with the attentional-arousal hypothesis and the directional hypokenisia) and the feed-forward model for anosognosia provide a satisfactory explanation for these deficits by suggesting that there is a dysfunction in the motor system. For the neglect patients the lesions affect the arousal which leads to the inability to prepare them for action. For the anosognosic patients the lesions lead to a failure to form motor intentions, to be more specific if the intention to move is impaired , then the comparator doesn’t receive instructions about the planned action and the patient considers that the movement has been executed, even if that didn’t happen. However, these theoretical interpretations of dysfunctions in motor control cannot account on their own for all the symptoms of neglect and anosognosia. Previous literature suggests that although the incidence of co-occurrence is high, there are cases where anosognosia and neglect appear independently and present double dissociations. Furthermore, as proposed by Marcel et al. (2004) both syndromes are multifaceted syndromes and it can’t be possible that only one theoretical interpretation can account for these. In conclusion, both anosognosia and neglect are very interesting phenomena which have captured the attention of many researches, however fundamental issues of theoretical interpretations have not still been answered.

Presidential Election Speech :: essays papers

Presidential Election Speech Hello my as many of you know my name is John Moriarty. I am running as the Democratic Candidate for President of the United States of America. So that you understand my positions on certain issues I will tell you a little about myself. I was born on August 16, 1948, my father was a former U.S. senator. I grew up in the Bronx, of New York, and I received a degree in Government from Harvard University. After I graduated I volunteered for enlistment in the U.S. Army and I served in Vietnam. When I returned to civilian life I married a woman named Nicole Swift, who is my wife to this day. We then started a family, in 1973 I had my first son named John, and in 1980 I had another son named James. I then studied Law at Vanderbillt Law School. In 1976 I was elected to represent New York in the U.S. House of Representatives, I was also elected to U.S. Senate in 1984 and again in 1990. I will now state my position on 4 separate issues that are current in the United Sates today. The first issue I will talk about is abortion. I am pro-choice, I do feel that women should have the right to choose if they want an abortion or not. Abortion is one of the most controversial issues in the United States today. One out of every three pregnancies never takes place because a woman has an abortion. It is understood that a new individual human begins growing in the mother’s uterus at fertilization. The term abortion refers to any premature expulsion of a human fetus. Approximately 93 percent of all induced abortions are done for elective, non-medical reasons. In 1973, the Supreme Court handed down Roe v. Wade and Doe v. Bolton decisions legalizing abortion in all 50 states during all nine months of pregnancy, for any reason, medical, social, or otherwise. This problem has split America in to two sides; pro - choice and pro - life. In January 22, 1973 U. S Supreme Court declared that a women had the " Fundamental Fight" to have an abortion. I agree with the ruli ng the Supreme Court made I will stand by it. The next issue I am going to elaborate on is gun control. I am very supportive of controlling the amount of guns that are distributed, I feel that there is too many crimes with illegal guns that happen everyday.

The Study Of Nanoscience And Nanotechnology Developments Environmental Sciences Essay

Interest in the issue of safeguarding the ecological environment has steadily increased in recent decennaries. Parallel to this involvement, some companies in assorted sectors have increased the degree and quality environmental information communicated to investors and stakeholders in developing a new sort of revelation, environmental revelation[ 1 ]. Several research workers have focused on the inducements for houses to set about voluntarily unwrap information on their environmental public presentation. Research on the issue have focused on different facets of this revelation as its impact on stock monetary values, outlooks of investors and their information demands, appraisals of concern hazard and impact on the cost of capital and the grounds for such revelation and the schemes pursued by houses. The bulk of surveies on environmental revelation are made in developed states like Canada, the United States, England and Australia, but what about the utility and relevancy of information environmental context of an emerging market? It is progressively common to hear the footings nanotechnology nanoparticles, nanostructures, etc, in mundane conversations, but for most people is still hard to conceive of these words out of context of scientific discipline or scientific discipline fiction[ 2 ]. However, the impact is undeniable and the survey of nanoscience and nanotechnology developments will hold immense impact on societal, cultural and economic life of all of us daily. Furthermore, the positive scenario presents the great benefits that will convey nanotechnology in the countries of wellness, nutrient, energy, environment, electronics and telecommunications, etc like C nanotubes can be used in golf nines for strength and elation, nanosilver is used as an antimicrobic agent in socks, and clay nanoparticles mean that beer can be packaged in plastic.[ 3 ] But nanotechnology besides brings many hazards with it ; environmental and wellness jeopardies and this should be disclosed to the populace so that they can take portion in the determination doing associating to the usage of this engineering and be able to forestall themselves from the possible jeopardies of nanotechnology and supply solutions to cut down these jeopardies. Some of the possible hazardeous belongingss of nanomaterials are that they might ‘penetrate the blood-brain barrier every bit good as the blood-lungs barrier. ‘[ 4 ]Hazards like these give us all grounds to fear about jobs like ‘asbestos 2.0 scenario, in which a considerable figure of merchandises incorporating nanomaterials might hold to be recalled from the market. There is already some grounds that certain nano tubings might hold belongingss similar to asbestos. ‘ Therefore, one can non be excessively certain for how long market participants, particularly consumers, will be ready to accep t populating under this Damocles ‘ blade of uncertainness. ‘[ 5 ]‘More specific safety concerns include most notoriously the impacts of nanosilver ‘s powerful antimicrobic consequence on ecosystems, and the possible asbestos-like effects of certain signifiers of C nanotube in the lung. ‘[ 6 ]But the problematic inquiry is that whether we are ready to accept the advantageous nanotechnology with all its disadvantages and sick effects. And are we prepared to battle the ailments of nanotechnology particularly when the degree of certainty required to take action is really high. This is so because the harmful impact of the nanomaterials has non been wholly established to everyone ‘s satisfaction. In this brief research, we try to seek whether the current Torahs plenty to cover with the jobs posed by the usage of nanomaterials or do we necessitate nano Torahs to cover with the unanticipated possible menaces. We besides discuss effects of nanotechnology and speak about the function of public engagement in nanotechnologies and how it can assist work out the conflicting visions for nanotechnology and sustainability. The purpose of this research is to measure the importance of the function of public engagement in sustainable nanotechnology development. The survey will besides accomplish the undermentioned aims Basic apprehension of nanotechnology Professionals and cons of nanotechnology Comparisons of policies and ordinances of nanotechnology of UK, US and China The importance of function of public engagement in nanotechnology Science and engineering brings both the benefits every bit good as losingss for the society and environment. The importance of this survey is that it helps measure how public engagement can assist cut down the negative impacts of scientific discipline and engineering in the society and environment.The survey will seek and reply the undermentioned research inquiries:What is nanotechnology What are its possible benefits and jeopardies? What is the importance of public engagement in the sustainable development of nanotechnology? The research is based on the aggregation of secondary informations. The information is extracted from a assortment of articles, diaries and books. Secondary research means that the information is gathered from publications, literatures, broadcast media and other non-human beginnings. The method used here for research is qualitative.Chapter 2NanotechnologyNanotechnology – a signifier of molecular technology – promises important societal benefits. The term â€Å" nanotechnology † encompasses an emerging household of heterogeneous engineerings including â€Å" nanosciences † and â€Å" nanotechnologies † enabling the use of affair at the atomic degree ‘ .[ 7 ] Nanotechnology is the new developing field of unifying scientific discipline and engineering. It is believed by its advocates that nanotechnology or ‘Nano ‘ ‘has the possible to alter the economic system and the criterions of life. ‘[ 8 ]It is seen as agencies to ‘longer, healthier life with riddance of life threatening diseases. ‘[ 9 ]‘Nanoscience is the survey of the cardinal rules of molecules and constructions with at least one dimension approximately between 1 and 100 nanometres ( one-billionth of a metre, or 10-9 ) , otherwise known as the ‘nanoscale. ‘[ 10 ]Called nanostructures, these are the smallest solid things possible to do. ‘[ 11 ] Nanotechnology is the ability to step, see, manipulate and industry things normally between 1 and 100 nanometres. A nanometre is one billionth of a metre ; a human hair is approximately 100,000 nanometres broad. In 2007, the planetary market for goods integrating nanotechnology was 147 billion. Lux Research undertakings that figure will increase to $ 3.1 billion by 2015[ 12 ]. Nanoscience can be described as those who study constructions or objects with at least one dimension in the nanometer graduated table. The analysis of these constructions includes the word picture of their belongingss ( whether mechanical, electronic, optical, magnetic, etc. ) ; the survey of interaction may hold with other nanostructures, with electromagnetic moving ridges, etc. , and the description of phenomena that occur at this degree[ 13 ]. On the other manus, nanotechnology corresponds to the proficient capacity to modify and pull strings affair to develop functional constructions and devices with dimensions below 100 nanometers, for possible technological applications. For illustration, a construction typical of the devices produced by the microelectronics industry current would be 100s of times larger than a nanostructure with dimensions below a few 10s of nanometres[ 14 ]. There is certain grade of singularity in these nano atoms and the scientists use this singularity to develop merchandises. Even though the nanotechnology is still on its research stage there are many articles/applications utilizing this engineering available in the market, such as miniaturized nanoscale detectors, and devices for screening DNA molecules, pigments, glare-reducing coating for spectacless and cars, organic visible radiation breathing rectifying tubes used in laptop computing machines, cell phones, and digital cameras, featuring goods, cosmetics, stain-resistant vesture, and cosmetics, sunblocks. From the environment position point this engineering is both advantageous and disputing. The benefits include ‘remediation, monitoring, and green production. For illustration, field trials indicate that Fe nanoparticles can be used to clean up dirt by neutralizing contaminations such as polychlorinated biphenyls, DDT, and dioxin. Possibly the greatest promise that nanotechnologies hold for the environment, nevertheless, may be the mode in which they could basically alter the manner goods are manufactured. Traditional fabrication requires big sums of natural stuffs bring forthing waste and risky by merchandises in the procedure. Nanotechnology allows for edifice from the underside up utilizing merely those molecules that are needed for the merchandise, thereby extinguishing waste at the beginning. ‘[ 15 ] Sadly plenty even though nanotechnology is positively touching are modern lives in legion ways really small is known about the jeopardies of this engineering. The jeopardies are chiefly related to the usage, industry and the disposal of merchandises prepared from nanotechnology. The informations associated with these hazards is really minimum and is n't easy available for the populace. Many feel that the ‘sheer assortment of the applications, belongingss expressed, paths of exposure and agencies of disposal make it peculiarly disputing to place, estimation, and pull off any hazards posed by nanotechnologies. Knowledge of the chemical belongingss of a substance when in majority may non assist foretell how that substance will act at the nanoscale. For illustration, aluminium is inert when it takes the signifier of a sodium carbonate can, but is extremely explosive in nanoform. ‘[ 16 ] The exceeding features of nanomaterials, jointly with the wellness and environmental jeopardies, ‘create what the Twenty Seventh Report of the UK ‘s Royal Commission on Environmental Pollution ( RCEP ) refers to as a ‘control quandary ‘ to which there are no simple and straightforward solutions. ‘[ 17 ]A The state of affairs becomes even worse because of the fact that we are non cognizant of all possible jeopardies which these nanomaterials are capable of doing and therefore no ‘appropriate hazard direction government ‘[ 18 ]can be established. ‘The hard inquiries are non about theA legitimacyA of modulating on the footing of safety, but about theA acceptabilityA and theA certaintyA of the hazard. Safety concerns about nanomaterials by and large include inquiries about the ability of substances at the nanoscale to get the better of some of the organic structure ‘s natural defense mechanisms, such as tegument, lungs, or the brain/blood barrier, and their possible to prevail in the environment. ‘[ 19 ]‘More specific safety concerns include most notoriously the impacts of nanosilver ‘s powerful antimicrobic consequence on ecosystems, and the possible asbestos-like effects of certain signifiers of C nanotube in the lung. ‘[ 20 ]A But there is still an on-going argument on jeopardies versus the benefits that this engineering brings with it. Although the Royal Commission on the Environmental Pollution ( RCEP ) is of the position that ‘the bing ordinances have the capacity to cover with the apprehended hazard associated with the nonomaterial, the job is that they do non adequately do so. ‘[ 21 ]Today nanotechnology is deriving a batch of attending and therefore it is really of import to pay attending to its social dimensions. Even though nanotechnology have found their manner into the bing ordinances it is still of import to ‘modify some ordinances within bing models to reflect the jeopardy presented by free nanoparticles and nanotubes. It has been recommended by the RS/RAEng that all relevant regulative organic structures review the capacity of bing ordinances to protect worlds and the environment from possible jeopardies associated with the usage of nanomaterials. ‘[ 22 ] Although it is felt by many that to a big extent the bing ordinances are adequate in integrated nanomaterials and the jeopardies caused by them but still there are some loopholes in the system. The averment that the current existing ordinances are adequate to integrate nanomaterials may be due to the fact that we are still incognizant of the possible dangers and menaces caused by these stuffs. This raises the inquiry that whether these ordinances are capable of accomplishing a nice degree of safety? Harmonizing to the RCEP study ‘nanotechnologies are covered by a complex set of bing regulative governments in the Fieldss of consumer, public wellness and environmental protection. ‘[ 23 ]However despite these regulative governments they still sometimes fail to account for 100 % safety. For this ground the RCEP came up with the Registration, Evaluation, Authorisation and Restriction of Chemical Substances or REACH. This has brought with it a immense alteration in the methodological analysis of covering with chemical substances. REACH does non incorporate anything specific refering nanotechnology ; it applies to new and existing chemicals and their usage, import and industry. Under this statute law it is mandatory for everyone covering with chemicals ; the makers, importers and other users to vouch that the chemicals used or manufactured does non negatively concern human wellness or the environment. It makes enrollment a compulsory demand for those covering with chemicals. This helps in obtaining relevant information about the chemicals being dealt with by the makers or the importers, giving the European Chemicals Agency an chance to measure and look into chemicals. This manner the activities that are harmful for the human wellness and environment can be singled out and can be restricted. REACH helps in advancing informed, transparent and unfastened decision-making, and provides a advanced and flexible regulative model. However, its relevancy and application to nanomaterials is limited. While REACH is puting its accent on the metric tons of chemicals being released, we fail to gain the injury caused by them at nano degree, such as ‘concerns associating to the inspiration of C nanotubes are non related, as such, to the measure of their production. Nanomaterials are evidently less likely to run into a tunnage threshold because, for any substance, there will be many more nanoparticles to the metric ton than larger atoms. ‘[ 24 ] Although one might reason that these ordinances can be applied to all harmful substances irrespective of their size or signifier but it is besides true that for such ordinances to go applicable the injury should be apparent on a really big graduated table to present possible menace to human life and the environment. It is merely so that the usage of those peculiar categories of nanomaterials will be classified as unacceptable and banned by the competent governments, which is practically about impossible.Professionals AND CONS OF NANOTECHNOLOGYScience and engineering are clearly societal existences by the fact that they belong to the same society. However, persons of the society have absolute right of oppugning on the benefits or negative impacts a peculiar innovation or development engineering could hold on society. Therefore, possible developments like nanotechnology or any new engineering that comes on the market are evidently susceptible to such appraisal. There are many illustrat ions of engineerings with good repute beginning subsequently on nem con being rejected, and frailty versa. It is in the current epoch the mass media can be constructed to be the Judgess of possible injuries or benefits of new engineerings. The chief job frequently viewed on the topic of unfavorable judgment is to acquire the public create their ain thought to happen the balance between the pros and cons[ 25 ]. This has happened historically with applications in the field of energy atomic, with the usage of assorted types of radiation, and more late with development of genetically modified beings, cloning and technology, merely to call a few.ProfessionalsThe possible application countries in which scientists say nanotechnology will impact positively are: Storage, production and energy transition, Increase in agricultural productiveness and pest sensing, Wastewater intervention and air pollution solutions, Diagnosis, monitoring and remedy of diseases systems drug disposal, Processing of nutrient and other consumer goods, New stuffs for assorted industries ( fabrics, automotive, building, picture, athleticss ) , General development of nanoelectronics, optoelectronics and bioelectronics and much more.ConEric Drexler in his book â€Å" The Rise of the machines to make † was the first to convey to the cognition of the general populace an overview of this new molecular engineering[ 26 ]. That describes non merely the tremendous capacity and possible nanotechnology, but besides the impact it may hold on the Fieldss medical, environmental and economic, every bit good as the hazards and frights associated[ 27 ]. However, many surveies are still seeking to find the impact of the nutrient produced from these GMOs in the wellness of consumers or environment in the short and long term. These ruinous visions about the possible negative deductions of developments in nanotechnology have non stopped the immense investings economic assistance for research in nanoscience and nanotechnology by big transnational companies in all industries and public in developed states. Unfortunately, it besides spends big sums of money to analyze the possible applications of Military nanotechnology. With horror we hear about arms biological / chemical computerized sufficiently intelligent devices little to avoid sensing, â€Å" smart † arms to kill merely soldier enemies and non guiltless people, etc. As we have seen, nanotechnology has a character genuinely multidisciplinary, with many possible application Fieldss for their development ( wellness, communications, ecology, nutrient, military, etcaˆÂ ¦ ) . So if we assess their impact on human activities as diverse, it is non we can non generalise and utilize the good-bad duality for making[ 28 ]. We realize that all the possi ble utilizations and hazards unwanted potency of nanotechnology are straight related. It is obvious that big corporations seeking to retrieve their investing and multiply in the shortest clip possible regardless of possible negative effects the engineering may hold on consumer and worker wellness or the environment[ 29 ]. The fact is that consumer ends up being a surety of large companies. For the state of affairs seems more awful and a grade of cynicism, so does with military applications in which the side that develops engineering will last no peculiar usage to their advantage to rule his opposition. However, due to the rapid development of scientific and chair a small the great duty of scientists to society, we can state that sometimes they are unable to spot in the short term possible negative impacts or that could hold applications in the hereafter their surveies, particularly when it comes to basic scientific discipline research or cardinal. The job with nanomaterials is that their dimensions are similar to some biological molecules and so they are really much capable of interacting with the biological molecules. These nanomaterials can travel within the organic structure of populating beings including worlds and can traverse cell membranes and reach the blood and variety meats like liver and bosom of the life organic structure. The indissoluble nanoparticles pose a greater menace to the human organic structure as they can lodge with within the organic structure for a longer clip. The nanoparticles which are inhaled by the human organic structure have the inclination of attaching itself to the lungs and thereby travel to assorted other variety meats and even damage the fetus in instance of pregnant adult females. These inhaled nanomateirals might take a toxic signifier within the human organic structure and cause lung redness and other jobs. Although the nanoparticles are used in drungs to move as a drug bearer and present more drugs to the mark cells but sometimes it becomes really difficult to separate the toxic atoms from the remainder, illustration the nanoparticles have the potency to traverse the blood encephalon barrier and present the drugs straight to the encephalon. However in stead of the limited information available about the sick effects of these nanoparticles it is rather possible for them to be toxic to the encephalon. The information on the side effects is scarce, it is expected to be much worse than what is known besides the effects are dependent on a scope of factors like age, unsusceptibility, presence of other pollutants, wellness jobs etc. Apart from the above discussed sick effects its sad to describe that there are about no publications on the sick effects of nanoparticles on animate beings and workss in the environment. Owing to the nature and inclination of the nanoparticles to attach with the cells and cross cellular membranes it can non be denied that they cause some serious harm to the works and carnal life along with human life. ‘Persistent indissoluble nanoparticles may do jobs in the environment that are much greater than those revealed by human wellness appraisals. ‘[ 30 ]CONCLUSION- ARE THE METHODOLOGIES AVAILABLE TO ASSESS THE HAZARDS ADEQUATE?With respect to this inquiry the Scientific Committee on Emerging and Newly Identified Health Risks ( SCENIHR ) is of the sentiment that although the bing methods seem appropriate but they are decidedly non adequate to turn to all sorts of environmental menaces. ‘More specifically, the manner of bringing of the nanoparticle to the trial system shoul d adequately reflect the exposure scenarios. Extra trials may be needed. Besides showing the dosage of exposure in footings of mass alone is non sufficient ; it besides needs to be expressed in footings of entire surface country, figure of atoms, or a combination of the two. The bing methods used for environmental exposure appraisal are non needfully allow. Therefore, the current hazard appraisal processs require alteration for nanoparticles. ‘[ 31 ] Besides harmonizing to SCENIHR despite the fact that there is an increasing focal point on the nanotechnology there is still ‘insufficient cognition and informations refering nanoparticle word picture, their sensing and measuring, the destiny ( and particularly the continuity ) of nanoparticles in worlds and in the environment, and all facets of toxicology and environmental toxicology related to nanoparticles, to let for satisfactory hazard appraisals for worlds and ecosystems to be performed. ‘[ 32 ] The SCENIHR commission was of the position that there are certain positions that need to be filled for an improved hazard appraisal for the merchandises and these include the word picture of mechanics, dynamicss, production and preparation of the nanotechnology and nanoparticles. Besides data on the toxicokinetic informations to place the mark variety meats and to determine the effects of the nano sized atoms on them. Harmonizing to the commission it is besides of import to hold full information of the occupational exposure and other possible wellness jeopardies on the workers who are involved in managing these nanosized atoms.

History Essay

1.   In your opinion, who started the Cold War? Explain in 5 sentences. In one opinion, the Cold War was not started by one side or the other.   The Cold War was more of a culmination of political, cultural and ideological differences than anything else(Pierpaoli).   This being said, in fairness, both the West and the East provoked hostilities during the Cold War through various attempts to promote their respective political systems throughout the world.   Ultimately, the Cold War was not decisively won by the West; rather, the West was able to hold out longer than the East. 2.   List three major prolonged conflicts in the Cold War. During the Cold War, three major prolonged conflicts that erupted were the Korean War (1950–1953); the Vietnam War (1946–1975); and the war in Afghanistan (1979–1989)(Pierpaoli). 3.   How did the Cold War influence society and culture? 3 sentences The Cold War influenced society and culture in many ways.   Culturally, the Cold War gave birth to an entire genre of literature and motion pictures/television- the classic story of the â€Å"secret agent†.   In terms of society, the Cold War divided society in terms of whether people, in both the East and West, supported capitalism or communism, and the many facets that each system offered (Pierpaoli). 4.   Evaluate the role of technology on the Cold War. Technology also played a role in the Cold War.   It was through surveillance technology that the United States was able to protect itself from Soviet aggression, such as the detection of missile sites in Cuba, a mere 90 miles from the US mainland (Pierpaoli).   Technology also helped the Soviets to detect an American U2 spy plane within their airspace- an incident which almost sparked World War III.   Lastly, and perhaps most importantly, the nuclear weapon technology which both the US and USSR possessed held the potential to destroy the planet. 5.What was Watergate and how did it influence the Vietnam War? Briefly describe. When one speaks of Watergate, they are usually referring to illegal actions taken by President Richard M. Nixon. Watergate is said to have begun when Nixon ordered one of his closest advisors, Henry Kissinger, to tap the telephone of a New York Time reporter in order to try to determine who was â€Å"leaking† information to the media about a secret bombing mission in Cambodia (Greene).   This influenced the Vietnam War in that the public learned of the many outrageous secret missions of the American military in Vietnam, raising public opposition to the war itself. 6.`A Short History of Terrorism,` write a paragraph explaining the difference in modern `terrorism` and its historical antecedents given in this article. The single most remarkable difference modern terrorism and its historical antecedents is the fact that modern terrorism is not meant to advance the agenda of a particular nation, but is driven by the belief by many Middle Eastern nations that the United States is an evil empire which God would like to see destroyed (Greenberg).   This type of religious zeal gives modern terrorism its sharp teeth and deadly venom. 7. Write a brief essay explaining your views on whether America should move beyond Affirmative Action at this time. Support your position. America should move beyond Affirmative Action for several key reasons; first, as we have seen in recent months, opportunities have opened up for minorities from the most powerful office in the United States to the areas of entertainment, the media, and the average job in any city in the nation.   Additionally, the increasing cultural diversity of America is transforming the demographic of the nation so that rather than minorities (Gryphon), there are any number of â€Å"mini-majorities† in place, thereby making favoritism for any given group both outdates and unnecessary. 8. Did women have a positive role in the progressive movement even before they had the right to vote? What was it? Describe briefly. Women most definitely had a positive role in the progressive movement even before they had the right to vote because it was the women in society which held families together as men worked outside of the home for long hours, making the woman the essential person who fed/mentored the children, etc.   It was in roles such as these that women were already asserting superiority before they could cast a ballot (Friedan). 9. Did the U.S. do everything it could to help the Jews in Europe? Is our current foreign policy a reaction to this situation? Briefly describe. In the final analysis, the US did not do everything it could to help the Jews in Europe, as there is evidence to suggest that the American government knew about the plight of Jews in Europe for several years before getting involved to protect the lives and interests of European Jews.   In a way, it can be said that our current foreign policy is a reaction to this past situation, as the US is both trying to prevent any aggression against the Jews of the magnitude of that of the past in Europe, and also compensating Jews for past injustices. 10. What were the roles of television and advertising in creating the consumer society of the post-World War II world? Briefly describe. Television and advertising created the consumer society of the post-World War II world, as they both shared with millions of war-weary Americans a wide variety of products that were now available after years of rationing and scarcity due to the war effort.   This led to a consumer society, as American people not only grabbed the items that they needed and could not get for many years, but also those new items that had not been available before.   All of this made the nation one of hardcore consumers, a trend that continues today.
