Warranty period The warranty period (usually one year) should be clearly defined in the purchasing documents order 20mg levitra soft visa. The warranty period is very useful in exposing possible failures of electronic components at an early stage buy 20mg levitra soft. It is recommended that the warranty period should start only when the equipment has passed all acceptance tests. Equipment should be put into clinical use as soon as possible in order to optimize the warranty period. There must be a clear understanding between the supplier and the end user as to how the warranty period will be influenced if a major part of the system needs to be replaced during the warranty period. The company should perform regular services and preventative maintenance procedures during this period. Service contracts A service contract should be negotiated, to include labour and either no spare parts, spare parts excluding the crystal, or all spare parts. The price of the service contract usually varies between 2 and 10% of the purchase price of the imaging system. The supplier should make available a qualified person to perform prevent- ative maintenance and servicing on the camera (proof of adequate training should be provided). In the event of system failure, the maximum response time of the service engineer should be specified (two hours is a typical figure). The maximum acceptable downtime per year should also be specified (10% of available working days is suggested). A penalty clause should be added to the contract if the supplier does not meet all the requirements. The supplier should supply a checklist of what will be performed during the services for preventative maintenance. The service engineer should leave on-site a record of all tests and checks performed. It is recommended that quality control tests such as those for uniformity and spatial resolution be performed before each service and repeated after completion, to evaluate the effectiveness of the service. General considerations The main imaging device in nuclear medicine is the gamma camera based on a sodium iodide detector, developed originally in 1958 by H. Although there are rectilinear scanners still in use, these will not be discussed. Multidetector systems are normally constructed using multiple gamma cameras that improve the efficiency of detection. Designs using multiple small detectors rather than conventional gamma cameras are also not in widespread use. The addition of coincidence circuitry to the conventional dual head gamma camera allows it to be used for ‘positron imaging’ as discussed in a later section of this manual. The design of gamma cameras has improved dramatically over a long period, with current devices being very much digital systems rather than simply being interfaced to an acquisition computer. Over the years the performance of cameras has also improved; not only is their resolution, uniformity and count rate capability better but also, more importantly, their stability is improved. Although there have been various attempts to design specialized gamma camera systems for specific applications, in general the more successful designs are those that provide flexibility. In many centres, the camera is required for different applications and, at the time of purchase, it is often difficult to predict what the ultimate application may be. Provided this flexibility is maintained, a dual head system has the advantage of improved throughput, and the low likelihood of both heads having problems means that a single head can be available for continued operation, even when the second head is non-functioning. A dual head system also offers the possibility for dual photon imaging, as discussed elsewhere. It is this flexibility that has resulted in the dual head camera currently being the most popular system. Although more expensive than a single head system, the dual head system is cost effective in terms of both throughput and flexibility. The computer is now an integral part of any imaging system, and consideration of not only speed but also the range of available software, connectivity and ease of upgrade become important considerations. There has been a trend in recent years towards standard computer platforms that can keep abreast of developments more easily than the older manufacturer-specific systems. Even though these systems tend to lag behind the general release of systems software, they generally offer a wide range of available peripherals and general software (including free software). Although there is a wide selection of advanced clinical applications software, the ability to develop user defined applications, without the need for advanced programming skills, remains a requirement that is not always available. Confirmation of results arising from application software is the responsibility of the site concerned. Particular care needs to be taken to ensure that interpretation is correct for the population concerned (e. There are many accessories for gamma cameras, including some that reduce overall reliability. One example is automated collimator exchangers that do not permit manual override and therefore result in the system being inoperable in the event of malfunction.
He order levitra soft 20 mg with visa, Adolph Meyer order levitra soft 20 mg fast delivery, and William James founded the National Association for Mental Health in 1909. During the same period the average number of inmates in an asylum jumped from 116 to 961. James and Barrett (2007) make the point that the asylum inmate was further isolated by the fact that asylums were built in the countryside when the rural population were fleeing to cities. They also say that isolation is compounded today by residence in suburbia which empty during working hours! Cremated remains of thousands of former inmates were kept in storage room and discovered in 2004! It was Conolly who was 3949 responsible for the opening of Colney Hatch Asylum in 1849. There, medical duties were divided between administration and the classification of inmates. John Conolly The Madhouse Act of 1828 sought to prevent collusion between the certifying physician and the owners of asylums. The Lunacy Act of 1845 gave birth to a National Lunacy Commission with responsibility for all types of institutions throughout the country, from prisons to madhouses. A Swiss doctor, Guggenbuhl, founded the first special residential institution for the mentally handicapped in 1841 in Abendberg. Jean Mark Gaspard Itard (1774-1838), a Parisian asylum doctor, tried to treat, 3951 Victor, the twelve year old feral ‘Wild boy of Aveyron’ in 1801, giving up in failure after six years. In British India, from the early 19th century, a policy of repatriation of the mentally ill back to England was used to disguise such vulnerability from the natives.

Other provisions entertained by the Act included an emergency order of short duration and special inquiries in the case of aristocrats. The same legislation allowed and for uncensored forwarding of certain letters written by inmates and for the relegation of restraint to the status of a specific medical intervention rather than something which any member of staff might apply. In 1879, Dr Abraham Cowles of the McLean Asylum, Massachusetts, started the first training school for attendants of the insane. It is generally held that McNaghten was a paranoiac (delusional disorder) or, favoured by Rollin, (1996) had a schizophrenic disorder. McNaghten was placed in Bethlem Hospital but was eventually moved to Broadmoor Asylum, dying there on 3rd May 1865 aged 52 years. A consequence of this Act was the locking away in asylums for long periods of retarded individuals who had outraged public morals, including girls who had become pregnant. The case of Sir Roger Casement provides an example of how homosexuality was viewed publicly in the early part of the 20th century: following the 1916 rebellion in Ireland, Casement was sentenced to death. Earlier, in the 1860s, Gustav Broun cauterised the clitoris and uterine cavity to reduce masturbation in women. Denial of masturbation was often met with disbelief and guilty depressives often exaggerated their sins. St Thomas Aquinas (1225-1274) stressed that sex was for marriage and only for procreative purposes. In 1708 the Dutch physician Herman Boerhaave (1668-1738) wrote that ‘too lavish’ a discharge of semen led to a wide variety of nervous problems that included convulsions, and dullness of the senses! S A D Tissot, a Swiss physician, published an influential book on the subject in 1758 which contained similar dire warnings. Benjamin Rush of Philadelphia published a book in 1812 in which he mentions masturbation as a cause of madness, impotence, poor sight, amnesia, and death!
One possible explanation for the al- most complete lack of argumentative discourse and the prevalence of informational content is that Sweden has managed to recruit five per cent of the adult population as donors 20mg levitra soft, that compares extremely well with other countries (the figure for Iceland is 2 generic levitra soft 20 mg free shipping. Donated blood is a lifeline for many people needing long-term treatments, not just in emergencies […] Ever since a national blood service was first created in 1946, we have relied on the generosity of blood donors […]. A ‘special reason’ may be an oblique reference to altruism, but potential donors are not required to donate for altruistic reasons, as other reasons will do just as well. With limited space given to altruistic motives, the psy- chological benefits for the donor are a recurrent theme: (17) I’m a Red Cross blood donor that won’t give up. Most healthy adults are eligible to give blood, however, there are some rea- sons a person may be deferred from donating temporarily, indefinitely, or per- manently. Your blood donations help treat cancer patients, traumatic accident and burn victims, newborn babies and mothers delivering babies, patients undergoing surgery, and many more. This lends further weight to Bhatia’s argument The Gift Relationship: Cultural Variation in Blood Donor Discourse 151 that to achieve an adequate characterisation of a particular genre, the institutional setting should be taken into account. A decision to donate your blood can save a life, or even several if your blood is separated into its components – red cells, platelets and plasma – which can be used individually for patients with specific conditions. Enlightened self-interest In a number of cases there is an appeal to potential donors to reflect on the fact that one day they themselves may need blood donated by others. En- lightened self-interest features prominently in the South African ap- peal: 152 William Bromwich (31) You could be next It’s not a nice thing to consider, but the fact is that you, a close friend, or a family member could well be the next car accident victim or surgery candidate requiring a transfusion. Unlike blood donated to the Red Cross or the Armed Services, it is not allocated to a national blood bank: (32) Giving Blood Saves Lives Your donation will help ensure an adequate supply for both children and adults who are patients within Lee Memorial Health System. Here the line between donors and recipients is blurred: they are no longer conceptualised as separate categories but as a fuzzy set (Lakoff 1987: 22), since donors may themselves need donations in the future. This brings to mind Malinowski’s (1922: 167) observation about gifts and counter-gifts in the Western Pacific as “one of the main instruments of social organisation […] and the bonds of kinship”. Self-interest It was initially expected that the institutional discourse would focus entirely on an appeal to altruism but this expectation was not con- firmed by the data. The following list of reasons to give blood begins with the offer of free juice and cookies, and conti- nues with other supposed benefits such as the chance to lose weight and to be excused from heavy lifting, before reaching the point where the donor is placed “on an equal footing with the rich and famous”. Paradoxically, an act that seems to be emblematic of altruism is moti- vated by a long list of self-centred considerations: (35) Top 10 Reasons to Give Blood The American Red Cross is constantly encouraging people to donate blood. It’s easy and convenient – it only takes about an hour and you can make the donation at a donor center, or at one of the many Red Cross mobile blood drives. The same line of reasoning appears on the Knoji Blood Donation web- site: (36) Donating Blood Is Healthy From a health standpoint, I can’t think of a better way for people with high blood pressure, migraines, or high cholesterol to let go of some waste. I do it to help with my blood pressure and migraines, as unloading two pints of blood [sic] is the best way for me to relieve pressure in my brain and my body. According to studies published in the American Journal of Epidemiology, blood donors are 88% less likely to The Gift Relationship: Cultural Variation in Blood Donor Discourse 155 suffer a heart attack. Urging people to donate blood more often, Harsh Vardhan said: “Regular blood donors, according to medical researchers, are 80 per cent less prone to diseases like heart attack, cancer, etc. Strands of argumentation in the discourse In each of the institutional appeals an attempt was made to identify the predominant strand of argumentation and the results are set out in the following matrix diagram. Although the discourse of altruism (upper left-hand quadrant) is predominant, the discourse of self-interest (up- per right-hand quadrant) also plays a significant role, and enlightened self-interest (lower left-hand quadrant) is also well represented, along with a strand focusing on organisational, scientific and technical is- sues (lower right-hand quadrant). Whereas in the institutional discourse there was a focus on altruism as the main motivation for blood donors, with some atten- tion to enlightened self-interest and organisational, scientific and tech- nical information, in the media reports the focus was primarily on self- interest, mainly considering the health benefits for the donor rather than the recipient. Concluding remarks This study investigated aspects of argumentation in the institutional blood donor discourse of a number of English-speaking countries and states, examining the strands of discourse based on altruism, en- lightened self-interest and self-interest. Institutional and cultural varia- tions were identified, not simply reflecting different national contexts, as in some instances cultural variation was identified also within the same national context. A stark contrast was evident between on the The Gift Relationship: Cultural Variation in Blood Donor Discourse 157 one hand the discourse of the institutional actors, in which altruism tends to prevail, along with elements of enlightened self-interest, and on the other hand the media reports, where self-interest clearly predo- minates. Healthcare professionals seeking to identify a judicious mix between the various motives to persuade blood donors to come forward to become regular donors might wish to compare their discursive practices with those characteristic of media reports as some mutual learning appears to be possible. Regardless of the specific approaches in the various national contexts, it is evident that public health information professionals need to continue to pay close attention to blood donor issues, also exploring the possibilities 3 afforded by social media. To conclude, the ongoing need for effective public health information is evident in this quotation from the Yelp review by a San Diego blood donor who was ‘weirded out’ not by the needles or the blood, but by the ignorance of potential donors: (40) I gave blood on one of their busses today. Introduction In the last two decades, Applied Linguistics and Translation Studies can be said to have experienced a similar shift: both disciplines have increasingly extended their focus of attention on social questions. It is true that the purpose of Applied Linguistics has always been “to solve or at least ameliorate social problems involving language” (Davies 1999: 1): but it is especially with the relatively new branch of Critical Applied Linguistics that issues such as identity, sexuality and power have become central questions to be addressed (Pennycook 2004: 785). Similarly, also Translation Studies have been more and more concerned with social factors involved in translation, with the translator’s social responsibility and issues of translation ethics (see for instance Pym 2006, Baker/Maier 2011). The ‘ethics of difference’ (Venuti 1998) has become a fundamental concept which has opened up many new lines of enquiry and has also influenced the authors of the present chapter. Being particularly interested in matters concerning human rights and vulnerable subjects, we have recently started to investigate communication to disabled people in three languages, i.
