Selected AbstractsResources Used by General Practitioners for Advising Travelers from New ZealandJOURNAL OF TRAVEL MEDICINE, Issue 2 2000Peter A. Leggat Background: The risks of the destination and any specific requirements for travel health advice may be obtained from a variety of resources. This study was designed to investigate the usefulness of various resources available in New Zealand for providing travel health advice and the extent to which GPs used these resources in providing travel health advice. Methods: Four hundred GPs (400/2830) were randomly selected from the register of the New Zealand Medical Council and sent self-administered questionnaires. Two reminders were sent. Results: Three hundred and thirty-two (332/400, 83%) GPs responded. The usefulness of various resources was reported, including Health Advice for Overseas Travellers (277/289, 96%), New Ethicals (256/278, 92%), New Zealand Public Health Report (79/164, 48%), International Travel and Health (41/144, 28%), computerized databases (6/122, 5%), journals (14/130, 11%), and other resources (44/139, 32%). Health Advice for Overseas Travellers was regarded as significantly more useful than International Travel and Health (x2= 4,68, df = 1, p < .05). Only 23% (70/309) of respondents indicated that they always used these resources in their practice of travel medicine. Fifty percent (154/309) of respondents indicated that they usually used these resources, while 27% (83/309) of respondents indicated that they used these resources sometimes. Only 1% (2/309) of GPs did not use resources at all for their practice of travel medicine. Conclusion: The most useful resource was Health Advice for Overseas Travellers, which outlines the New Zealand recommendations for medical practitioners providing travel health advice. It may be useful for GPs to gain access to and training in association with a greater range of specialist resources to use in conjunction with the provision of travel health advice. These might include international guidelines, journals, and access to computerized databases and the internet. With the recent introduction of a widely accessible computerized database in New Zealand, follow-up studies could be instituted to determine if GPs' use of computerized databases becomes more widespread and whether access to and use of these computerized databases influences the provision of travel health advice by GPs. Further studies are needed to examine the appropriateness of the advice provided by the various resources used by GPs in New Zealand. [source] Review article: investigational agents for chronic hepatitis CALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2009A. J. V. THOMPSON Summary Background, The need for effective treatment for chronic hepatitis C infection has driven the development of novel antiviral agents that target specific steps in the viral replication cycle. Aim, To evaluate the current literature concerning investigational agents for chronic hepatitis C virus infection. Methods, Resources used included PubMed, conference proceedings from the American and European Liver Associations' meetings 2005,2008 and the National Institute of Health's clinical trials website (http://www.clinicaltrials.gov). The focus was restricted to investigational agents that have progressed beyond preclinical development. Results, Over 50 investigational agents for chronic hepatitis C infection are currently in clinical development. Specifically targeted anti-viral therapy for HCV (STAT-C) shows great promise with NS3/4a protease inhibitors now entering phase 3 programmes. New interferon-, and ribavirin formulations aim to optimize anti-viral efficacy yet limit toxicity. Other candidates include novel immunomodulators and therapeutic vaccines. Conclusions, A new era of therapy for chronic hepatitis C beckons, promising increased cure rates with shortened duration of therapy. However, the era will not be without challenges including viral resistance, drug toxicity and the need to optimize combination therapy in the face of a rapidly evolving therapeutic arsenal. [source] Using real patients in problem-based learning: students' comments on the value of using real, as opposed to paper cases, in a problem-based learning module in general practiceMEDICAL EDUCATION, Issue 1 2001Jane Dammers Objectives To explore the feasibility and value of using real patients as trigger material in problem-based learning (PBL). Design A questionnaire was given to all students participating in a PBL module including a question about ,the added value of using real, as opposed to paper cases', in problem-based learning. Resources used by students and assessment of feasibility were recorded by the course tutors. Setting A 7-week student-selected problem-based module in general practice in the fourth-year undergraduate medical curriculum, University of Newcastle upon Tyne. Subjects 69 students participating in the module over 2 years. Results All students valued the use of real patients. A total of 10 categories were identified, all congruent with accepted educational principles for effective adult learning. Real patients stimulated the use of a very wide range of resources and imaginative presentation of what had been learned. Conclusion Real patients are potent trigger stimuli in problem-based learning. The use of real patients in this general practice-based module presented no organizational or ethical difficulties. Their use should be considered more widely. [source] An economic evaluation of atenolol vs. captopril in patients with Type 2 diabetes (UKPDS 54)DIABETIC MEDICINE, Issue 6 2001A. Gray Abstract Aims To compare the net cost of a tight blood pressure control policy with an angiotensin converting enzyme inhibitor (captopril) or , blocker (atenolol) in patients with Type 2 diabetes. Design A cost-effectiveness analysis based on outcomes and resources used in a randomized controlled trial and assumptions regarding the use of these therapies in a general practice setting. Setting Twenty United Kingdom Prospective Diabetes Study Hospital-based clinics in England, Scotland and Northern Ireland. Subjects Hypertensive patients (n= 758) with Type 2 diabetes (mean age 56 years, mean blood pressure 159/94 mmHg), 400 of whom were allocated to the angiotensin converting enzyme inhibitor captopril and 358 to the , blocker atenolol. Main outcome measures Life expectancy and mean cost per patient. Results There was no statistically significant difference in life expectancy between groups. The cost per patient over the trial period was £6485 in the captopril group, compared with £5550 in the atenolol group, an average cost difference of £935 (95% confidence interval £188, £1682). This 14% reduction arose partly because of lower drug prices, and also because of significantly fewer and shorter hospitalizations in the atenolol group, and despite higher antidiabetic drug costs in the atenolol group. Conclusions Treatment of hypertensive patients with Type 2 diabetes using atenolol or captopril was equally effective. However, total costs were significantly lower in the atenolol group. Diabet.

All schools were required to adopt the NLS Literacy Hour unless they could show their preferred programme would result in raised levels of achievement. My experience of delivering the Literacy Hour has been a process of adaptation to the needs of my pupils, who are drawn mainly from groups whose language backgrounds differ from that which is dominant in school. I have found that the requirements of NLS, together with many of the commercial resources used to teach it, are not appropriate for pupils from these groups and a question arose: is it the pupils who are in some way deficient or is it the approach and the resources being used? This article takes a case study of the use of a commercially produced resource to explore the model of language implicit in NLS, the kinds of resources it generates and the ways in which this creates failure in pupils from different language backgrounds. It then considers the New Literacy Studies and their implications for an alteration in our approach. [source] On the efficiency of PGPS-based packet and cell switching technologies for traffic with guaranteed delayEUROPEAN TRANSACTIONS ON TELECOMMUNICATIONS, Issue 4 2003Fulvio Risso Circuit switching, suited to providing real-time services due to the low and fixed switching delay, is not cost effective for building integrated services networks because it is based on static allocation of resources which is not efficient with bursty data traffic. Moreover it cannot handle flows that are not integer multiple of 64,Kb/s, preventing the usage of low bit rate codecs. This work explores the most suitable alternatives to the circuit switching technology (i.e. packet/cell switching) from the efficiency point of view, assuming that a PGPS scheduler is deployed in the network nodes. The paper defines an index to measure the efficiency of packet telephony, i.e. the volume of real-time traffic with deterministically guaranteed quality plus the amount of data carried related to the amount of network resources used. Furthermore it determines the maximum efficiency obtainable by packet networks, compares different network technologies and explores the problems of the deploying of low bit-rate codecs.

[source] Health and social care costs for young adults with epilepsy in the UKHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 5 2010Jennifer Beecham PhD Abstract Maintaining contact with services will help improve clinical and social outcomes as children with epilepsy move into their adult lives. This study has collated evidence on the extent to which young adults with epilepsy are supported by health and social care services posttransition, and the costs of such support. UK prevalence and service use data were taken from policy and research literature, as well as national data sets and reports. Costs were attached to these data to arrive at agency and overall total costs. There are approximately 42 000 young adults (18,25 years) with epilepsy costing the UK health and social care budgets £715.3 million per annum, on average £17 000 per young adult with epilepsy. A further £61 million falls to the social security budget. Most young adults with epilepsy will rarely use these services, but those with additional health needs have high and often long-term support needs, including supported accommodation and personal care. Current resources used by these young adults are summarised but deficits in service availability can mean long waiting times and sub-optimal treatment. Young adults also want more support to help them take advantage of education and employment opportunities and more information about managing the impacts of epilepsy on their lives. Improving services will cost money, but has the potential to lead to better outcomes for young adults. [source] An alternative approach to conceptualizing interviews in HRD researchHUMAN RESOURCE DEVELOPMENT QUARTERLY, Issue 2 2007Jia Wang Qualitative researchers in human resource development (HRD) frequently use in-depth interviews as a research method. Yet reports from qualitative studies in HRD commonly pay little or no analytical attention to the co-construction of interview data. That is, reports of qualitative research projects often treat interviews as a transparent method of data collection, with the contents of answers to interview questions as data that mirror people's views and experiences of a "world out there." In this article, we demonstrate how an ethnomethodological approach to the reanalysis of interview data drawn from a qualitative study in HRD treats the research interview as a socially situated setting in which narrative data are co-constructed by speakers. From this perspective, it is possible to see how speakers produce unstable category descriptions and morally laden portrayals in order to support their claims. We argue that this type of analysis is useful for three reasons: (1) it provides a way to investigate instances in which interview accounts may prove analytically problematic; (2) it makes evident how interview data are produced by illuminating the conversational resources used by both researcher and participant to co-construct descriptions; and (3) it provides a new analytical approach for HRD researchers, who have until now relied primarily on thematic representations of findings derived from inductive analyses of interview data. By using this approach to analyze or reanalyze interview data, researchers may gain further insight into the research topic and the interaction that produced the interview data in a particular socially situated setting. This approach reveals the practical reasoning, identities, and moral assumptions demonstrated in talk by speakers. Such analysis, we argue, assists in HRD theory building in that it contributes to complex interpretations of data that respond to new and different questions, including methodological questions. [source] Representations of ethnicity in people's accounts of local community participation in a multi-ethnic community in EnglandJOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 1 2002Catherine Campbell Abstract In this paper we examine the impact of the social construction of ethnic identities on the likelihood of local community participation. We do so in the context of an applied interest in the current policy emphasis on partnerships between government and local communities in initiatives to reduce health inequalities, and a conceptual interest in the role of social representations in perpetuating unequal power hierarchies. Semi-structured interviews were conducted with 75 residents of a deprived multi-ethnic area in south England. Informants described themselves as African-Caribbean, Pakistani and White English; half men and half women, aged 15,75. We draw attention to the way in which ethnic identities may be constructed in ways that undermine the likelihood of local community participation. Stereotypical representations of ethnically defined ingroups and outgroups (the ethnic ,other') constituted key symbolic resources used by our informants in accounting for their low levels of engagement with local community networks. We examine the content of these stereotypes, and highlight how their construction is shaped by historical, economic and social forces, within the context of the ,institutional racism' that exists in England. Copyright © 2001 John Wiley & Sons, Ltd. [source] Mycorrhizal fungi as mediators of defence against insect pests in agricultural systemsAGRICULTURAL AND FOREST ENTOMOLOGY, Issue 4 2009Rachel L. Vannette Abstract 1Below-ground organisms influence above-ground interactions in both natural and agricultural ecosystems. Among the most important below-ground organisms are mycorrhizal fungi, comprising ubiquitous and ancient plant mutualists that have significant effects on plant growth and fitness mediated by resource exchange with plants. In the present study, we focus on the effects of arbuscular mycorrhizal fungi (AMF) on crop defence against insect pests. 2AMF alter the availability of resources used by crop plants to manufacture defences against pests and to compensate for pest damage. However, AMF also provide plants with nutrients that are known to increase insect performance. Through potentially opposing effects on plant nutritional quality and defence, mycorrhizal fungi can positively or negatively affect pest performance. 3Additionally, AMF may directly affect gene expression and plant defence signalling pathways involved in the construction and induction of plant defences, and these effects are apparently independent of those caused by nutrient availability. In this way, AMF may still influence plant defences in the fertilized and highly managed systems typical of agribusiness. 4Because AMF can affect plant tolerance to pest damage, they may have a significant impact on the shape of damage,yield relationships in crops. Potential mechanisms for this effect are suggested. 5We highlight the need for continuing research on the effects of AMF identity and the abundance on crop defences and tolerance to pest attack. Much work is needed on the potential effects of mycorrhizal colonization on plant signalling and the induction of direct and indirect defences that may protect against pest damage. [source] Food Waste Management by Life Cycle Assessment of the Food ChainJOURNAL OF FOOD SCIENCE, Issue 3 2004THOMAS OHLSSON ABSTRACT: In the past, environmental activities in the food industry used to be focused on meeting the requirements set by authorities on waste and sewage disposal and, more recently, regarding emissions to air. Today environmental issues are considered an essential part of the corporate image in progressive food industries. To avoid sub-optimization, food waste management should involve assessing the environmental impact of the whole food chain. Life cycle assessment (LCA) is an ISO-standardized method to assess the environmental impact of a food product. It evaluates the resources used to perform the different activities through the chain of production from raw material to the user step. It also summarizes the emission/waste to air, water, and land from the same activities throughout the chain. These emissions are then related to the major environmental concerns such as eutrophication, acidification, and ecotoxicity, the factors most relevant for the food sector. The food industry uses the LCAs to identify the steps in the food chain that have the largest impact on the environment in order to target the improvement efforts. It is then used to choose among alternatives in the selection of raw materials, packaging material, and other inputs as well as waste management strategies. A large number of food production chains have been assessed by LCAs over the years. This will be exemplified by a comparison of the environmental impact of ecologically grown raw materials to those conventionally grown. Today LCA is often integrated into process and product development, for example, in a project for reduction of water usage and waste valorization in a diversified dairy. [source] Survey of recently board-certified prosthodontists on the board-certification process.JOURNAL OF PROSTHODONTICS, Issue 3 2003Part 2: Preparation, impact Purpose A 2-part survey of recently board-certified prosthodontists was conducted in 2001. The first part of the survey, published in June 2003, determined the trends that assisted the candidates in attaining diplomate status. The second part of the survey was done to determine the preparation methods and resources used to prepare for the examination, the most difficult part of the examination, the most gratifying aspect of becoming board-certified, their current employment status, and whether board certification had any positive impact on their employment. Materials and Methods A questionnaire was mailed to 176 diplomates who had become board certified between the years 1993,2001. Of these, 131 board-certified prosthodontists returned the completed survey, resulting in a response rate of 74%. Results Results from this survey showed that 91% of the diplomates had taken the American College of Prosthodontists (ACP) Board Preparation course; most of the diplomates (41%) prepared for the boards by reviewing prosthodontic literature, reading textbooks, using the ACP Study Guide, and seeking the help of other board-certified prosthodontists; 89% of the diplomates felt that achieving board certification had a positive influence in their employment; 39% of the diplomates indicated that Part 2 of the examination was the most difficult to prepare for, and 41% indicated that Part 2 was the most difficult section; the majority of diplomates (31%) were employed by the military, and the most gratifying aspect of becoming board-certified was personal accomplishment (83%). Conclusions Trends were observed regarding prosthodontists who succeeded with their efforts to challenge the board examination. The majority of the diplomates were employed by the military. Most of the respondents indicated that they took the ACP Board Preparation course and found it helpful. The largest percentage of respondents reported that Part 2 was both the most difficult part to prepare for, as well as the most difficult to complete. The most gratifying aspect of becoming board-certified was personal accomplishment. [source] Rhotacization and the ,Beijing Smooth Operator': The social meaning of a linguistic variable1JOURNAL OF SOCIOLINGUISTICS, Issue 2 2008Qing Zhang Recent sociolinguistic studies on style have focused much attention on the construction of social meaning in situated discursive practices. Despite a general recognition that the linguistic resources used are often already imbued with social meanings, little research has been done on what these meanings may be. Focusing on rhotacization, a sociolinguistic variable in Beijing Mandarin, this article explores its imbued social meanings and sociocultural associations. I demonstrate that rhotacization takes on semiotic saliency through co-occurrence with key Beijing cultural terms and frequent use in written representations of authentic Beijing-ness. Furthermore, this feature is associated with the ,Beijing Smooth Operator,' a salient male local character type, and is ideologically construed as reflecting its characterological attributes. The findings of this study shed light on the meaning potential of a linguistic variable, rhotacization in this case, which can enhance understanding of the possibilities and constraints for its use and meaning in new contexts.

[source] Treatment of ulcerative colitis from the patient's perspective: a survey of preferences and satisfaction with therapyALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2009J. R. GRAY Summary Background, Data available regarding patient perspectives on ulcerative colitis (UC) and their preferences and satisfaction with therapy are limited. Aims, To examine the preferences of UC patients to understand better what they look for in a therapy when managing their disease, as this may influence overall medication adherence. Methods, The study surveyed 100 Canadian UC patients on topics including educational resources used to learn about the disease, medication attributes that are most valued and preferred by the patient and satisfaction with current therapy. Results, Overall, efficacy- and safety-related medication attributes were rated by patients to be more important than those related to dosing regimen (e.g. dosing frequency, number of pills), cost and formulary coverage. In pair-wise comparisons of specific medication attributes, UC patients rated speed of symptom relief and few side effects as the most important factors when considering a UC medication (preferred on average 84% and 74% of the time respectively). Conclusion, This study provides insight into UC patient preferences and satisfaction with therapy that may be important when counselling on treatment options, and generates relevant discussions on adherence. Larger studies may be warranted to examine further how these findings can be extrapolated to broader UC populations. [source] Compensation costs of work-related back disorders among union carpenters, Washington State 1989,2003AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 8 2009Hester J. Lipscomb PhD Abstract Background We measured resources used to provide medical care and to estimate lost productivity represented by payments for lost work time or impairment for work-related back injuries among a large cohort of union carpenters over 15 years. Methods Using administrative data we identified a cohort of carpenters, their hours worked, their workers' compensation claims and associated costs. After adjustment for inflation and discounting to 2006 dollars, yearly costs for injuries and payment rates based on hours worked were calculated. Using negative binomial regression, dollars paid per claim were modeled based on age, gender, union tenure, and predominant type of work of the carpenter and whether the injury resulted from overexertion or acute trauma. Results Workers' compensation costs for back injuries exceeded $128 million dollars between 1998 and 2003, representing payments of $0.97 for each hour of work. Costs per hour of work declined substantively over time due largely to declining overexertion injury rates. Traumatic injuries, though less common than overexertion injuries, were more expensive. Costs increased with the number of prior back injuries and with increasing age, beginning as early as age 30. Conclusions Increasing costs even among relatively young carpenters likely reflect the heavy nature of their work rather than simply the effects of biological aging. Musculoskeletal back problems remain a common, and consequently costly, source of injury among these carpenters that needs to be addressed through engineering modifications; there are also clearly needs for prevention of the often more costly back injuries associated with acute trauma.

[source] The Expansion, Diversification, and Segmentation of Power in Late Prehispanic NascaARCHEOLOGICAL PAPERS OF THE AMERICAN ANTHROPOLOGICAL ASSOCIATION, Issue 1 2004Christina A. Conlee During the Late Intermediate Period (A.D. 1000,1476) the organization and foundation of power in Nasca was transformed from earlier times. Previously, religious resources were central to the development and maintenance of the political and social hierarchy. After the collapse of the Wari Empire and a period of balkanization, the resources used to establish and maintain power broadened considerably. The expansion of the power base into new realms coincided with an increase in the number of local elites in the drainage. There was no longer a focus on regional ceremonial centers; instead, elites were able to build power through a variety of activities including exchange, craft production (with a focus on utilitarian items), feasting, community-based ritual activities, and probably warfare and defense. During this period the levels of the political hierarchy grew and a more heterarchical type of regional polity developed. [source] An inquiline fig wasp using seeds as a resource for small male production: a potential first step for the evolution of new feeding habits?BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 1 2007RODRIGO A. SANTINELO PEREIRA The processes allowing evolutionary transitions in resources used by parasitic wasps are largely unknown. Microhymenopteran communities associated with figs could provide a model system to investigate such transitions. We investigate here a species of genus Idarnes. The larvae generally develop as inquilines of the pollinating wasp larvae. However, in figs where the parasitic pressure is high, eggs are laid in developing seeds. These eggs turn into small males. This is the first report of seed consumption by a fig wasp. Using an alternative resource to produce small males could provide a pathway to select for increased ability to use this resource and hence provide an intermediate step for evolving the capacity to use new resources. © 2007 The Linnean Society of London, Biological Journal of the Linnean Society, 2007, 92, 9,17.
