Selected AbstractsEthical problems in cytologyCYTOPATHOLOGY, Issue 1 2004. Znidar Great advances in medical science have raised a number of ethical issues, many of which affect cytopathology. Some of the main issues addressed in this paper relate to the organization of a cytology laboratory: internal and external quality control, adequate staffing levels and staff education, cytopathology reporting format and contents, confidentiality issues, relationship with the clinicians and involvement of cytopathologists in clinical management teams. Quality control has to be provided within cytology departments but external quality assurance is also essential, with national monitoring. New technologies should be used according to the best scientific methods, following cytological analysis. Scientific work in cytology has to respect the general principles of scientific ethics. The patient's interest has to be the main reason for such work.

It is one of six agricultural research stations of the Swiss Department of Agriculture and the leading national research institute in dairy technology and consulting. It is part of the Swiss Centre of Competence for Animal Production and Foods of Animal Origin. Its mission is to improve the competitive position of the Swiss milk producers and dairy industry. The institute is organized into three functional areas corresponding to its well-established core competencies: (1) production of raw milk cheese and microorganisms for fermentation, (2) knowledge transfer and consultation for the dairy industry and beekeeping, and (3) testing of, and providing expertise on dairy and bee products. Research work is carried out using a multidisciplinary approach in a matrix organization. Two product- and customer-orientated technology units and one unit for consulting, contractual work and other services for the dairy industry are supported in their projects by three scientific and technical units (microbiology; chemistry, physics and sensory analysis; engineering and production) as well as by a unit offering central services. The 4-year research programmes are based on the strategic goals of the agricultural policy as well as on the current needs of the dairy industry. An advisory board oversees the preparation and execution of the projects. FAM is connected to an international network for both scientific work and supervisory tasks. Work is carried out within the background of the political strategy of a sustainable development including economic, ecological and social aspects. A primary research focus is therefore the avoidance of excessive processing of milk and dairy products, and keeping products natural and free of residues by applying only minimal, unavoidable treatments and additives. [source] Changing trends in gastrointestinal disease in the Asia,Pacific regionJOURNAL OF DIGESTIVE DISEASES, Issue 4 2007KL GOH The new millennium has seen distinct changes in the pattern of gastrointestinal disease in the Asia,Pacific region. These changes are important as more than half of the world's population come from the region and therefore impact significantly on the global disease burden. The highest incidence of gastric cancer (GCA) has been reported from Asia and GCA remains a very important cancer. However time-trend studies have shown a decrease in GCA incidence in several countries in Asia. A rise in cardio-esophageal cancers as seen in the West has not been reported. On the other hand, colorectal cancer has been steadily increasing in Asia with age-standardized incidence rates of some countries approaching that of the West. The pattern of acid-related diseases has also changed. Gastroesophageal reflux disease is a fast emerging disease with an increasing prevalence of reflux esophagitis and reflux symptoms. The prevalence of peptic ulcer disease has at the same time declined in step with a decrease in H. pylori infection. Many of the changes taking place mirror the Western experience of several decades ago. Astute observation of the epidemiology of emerging diseases combined with good scientific work will allow a clearer understanding of the key processes underlying these changes. With rapid modernization, lifestyle changes have been blamed for an increase in several diseases including gastroesophageal reflux disease, nonalcoholic fatty liver disease and colorectal cancer. A worrying trend has been the increase in obesity among Asians, which has been associated with an increase in metabolic diseases and various gastrointestinal cancers. Conversely, an improvement in living conditions has been closely linked to the decrease in GCA and H. pylori prevalence. [source] Evaluating Permanent Disability Ratings Using Empirical Data on Earnings LossesJOURNAL OF RISK AND INSURANCE, Issue 1 2010Jayanta Bhattacharya Workers' compensation systems are typically designed to assign higher permanent disability benefits to workers with more severe disabilities. However, little or no scientific work exists to guide the design of ratings systems to properly account for the amount of earnings power lost due to disability. In this article, we examine the effectiveness of disability ratings using matched administrative data on ratings and earnings for a large, representative sample of permanent disability claimants in California. We find that while workers with higher ratings do experience larger earnings losses on average, there are large and persistent differences in average earnings losses for similarly rated impairments in different parts of the body. We then explore how adjusting permanent disability ratings to reflect cross-impairment differences in earnings losses can affect the equity of permanent disability benefits. Adjusting disability ratings to account for typical earnings losses reduces cross-impairment differences substantially. The adjusted ratings result in a more equitable distribution of disability benefits across workers with different impairments. [source] The role of evidence in interpretations of the scientific work of Karl LashleyJOURNAL OF THE HISTORY OF THE BEHAVIORAL SCIENCES, Issue 3 2002Donald A. Dewsbury I discuss some of the issues underlying the different perspectives of Nadine Weidman and myself on the scientific oeuvre of Karl Lashley. I emphasize that our disagreements concern the kind of evidence needed to support specific claims more than any differences in our models of science. © 2002 Wiley Periodicals, Inc. [source] Backing into the FutureMEDICAL ANTHROPOLOGY QUARTERLY, Issue 4 2001Charles Leslie The professionalization of anthropology was grounded in a naturalistic tradition of field research. The empirical particularism of fieldwork wedded aesthetic and humanistic concerns with those of science in a discipline that assumed a species-wide and long-time perspective while focusing on the description and comparisons of local variations. Scientific progress has occurred in anthropology over the past century despite the distortions of colonialism, the Cold War, and other historical circumstances. Controversies about good and bad scientific work and about the humanistic character of anthropology have been an ongoing aspect of our discipline. The historical development of medical anthropology and important recent publications in this specialty illustrate the nature of the encompassing discipline and provide the ground on which 21st-century scholars will carry the science forward, [anthropological tradition, scientific progress, humanistic science] [source] Mediating Among Scientists: A Mental Model of Expert PracticeNEGOTIATION AND CONFLICT MANAGEMENT RESEARCH, Issue 4 2009Kenneth Kressel Abstract Despite the considerable research on mediator behavior, the cognitive structures and processes that presumably guide the strategic and tactical choices of professional mediators are poorly understood. The current study made use of a reflective case study method to explore in considerable detail the strategic thinking of five experienced mediators. The project was conducted at the National Institutes of Health whose Office of the Ombudsman (OO) mediates disputes among the institute's scientists. Eighteen cases were studied. The thinking of the mediators in these cases displayed regularities that are described in terms of the ombuds team's working mental model of mediation. The mental model consists of two strongly contrasting intervention scripts: a deep problem-solving script (DPS) focused on identifying and addressing latent issues of an interpersonal or systemic kind and a tactical problem-solving script (TPS) focusing instead on the issues as presented by the parties. The tactical script was applied in either an integrative bargaining mode or a more distributive quasi-arbitration approach. The choice of which script to follow in a given case is determined by first order decision rules concerning the existence and nature of any latent problems that may be present, and second order decision rules concerning the parties' capacity to engage in "deep" problem-solving. Despite their very different foci, both DPS and TPS appear to follow the same metascript of problem-solving stages, beginning with an intensive diagnostic phase during which the decision rules are applied and a script "selection" is made. DPS is the preferred intervention mode of team members. Every case began with at least a preliminary effort to search for and address latent causes, and team members expressed dissatisfaction if they could not apply DPS in cases where latent problems were thought to be fueling the conflict. However, ombudsmen used the scripts flexibly and switched to TPS if DPS was unnecessary or impractical. Both scripts produced agreements that were useful to the parties and to the institution's scientific purposes, particularly the fostering of scientific competence. The mental model is heavily shaped by the social context in which the ombudsmen function. Thus, the primacy of DPS in the model appears to be due to the fact that the ombudsmen are "repeat players" in the life of the NIH and therefore in a position to become adept at recognizing the latent sources of its dysfunctional conflicts, are under a strong role mandate as ombudsmen to pay attention to covert patterns of organizational dysfunction, and deal with disputants pressed to address latent issues blocking scientific work. [source] A possible role of social activity to explain differences in publication output among ecologistsOIKOS, Issue 4 2008Publication output is the standard by which scientific productivity is evaluated. Despite a plethora of papers on the issue of publication and citation biases, no study has so far considered a possible effect of social activities on publication output. One of the most frequent social activities in the world is drinking alcohol. In Europe, most alcohol is consumed as beer and, based on well known negative effects of alcohol consumption on cognitive performance, I predicted negative correlations between beer consumption and several measures of scientific performance. Using a survey from the Czech Republic, that has the highest per capita beer consumption rate in the world, I show that increasing per capita beer consumption is associated with lower numbers of papers, total citations, and citations per paper (a surrogate measure of paper quality). In addition I found the same predicted trends in comparison of two separate geographic areas within the Czech Republic that are also known to differ in beer consumption rates. These correlations are consistent with the possibility that leisure time social activities might influence the quality and quantity of scientific work and may be potential sources of publication and citation biases. [source] Empirically informed approaches to topics in suicide risk assessmentBEHAVIORAL SCIENCES & THE LAW, Issue 5 2004LaRicka R. Wingate M.S. The purpose of this article is to approach topics in suicide risk assessment from a scientifically informed standpoint. We summarize and elaborate a general framework for an empirically supported best practice recommendation in evaluating suicide potential and minimizing risk. This risk assessment framework provides a concise heuristic for assessment of suicidal symptoms, points the way to relatively routinized clinical decision-making and activity, and is compatible with best practices relevant to the legalities of suicide risk assessment. Having established a general and scientifically based framework for risk assessment, we go on to address the other questions noted above, with reference to the framework and to our ongoing scientific work. We conclude by summarizing all the work and providing clear and concise clinical recommendations based thereon. Copyright © 2004 John Wiley & Sons, Ltd.

[source] Production of hydrogen via glycerol steam reforming in a Pd-Ag membrane reactor over Co-Al2O3 catalystASIA-PACIFIC JOURNAL OF CHEMICAL ENGINEERING, Issue 1 2010A. Iulianelli Abstract Generally, biodiesel fuel, when converted from vegetables oils, produces around 10 wt% of glycerol as a byproduct, which could be used for producing hydrogen by a steam-reforming reaction. Different scientific works have been realized in conventional reactors on the steam reforming of glycerol (GSR) in the aqueous or the gas phase. High reaction pressure and a relatively small catalyst deactivation are noticed when GSR is carried out in an aqueous phase, whereas the catalyst deactivation is the main disadvantage in the gas phase. In this work, GSR reaction was performed in a perm-selective Pd-Ag membrane reactor (MR) packed with a Co-Al2O3 commercial catalyst in order to extract a CO-free hydrogen stream and also enhance the performances in terms of glycerol conversion and hydrogen yield with respect to a traditional reactor (TR), both working at weight hourly space velocity (WHSV) = 1.01 h,1, 400 °C and H2O/C3H8O3 = 6/1. In MR, a maximum glycerol conversion of around 45.0% was achieved at 1.0 bar as reaction pressure, whereas it was around 94% at 4.0 bar. Moreover, as best value, more than 60.0% of CO-free hydrogen recovery was achieved in the MR at 4.0 bar and 22.8 of sweep factor (sweep gas to glycerol ratio).

[source] Simulation of drying process of corn kernels during microwave and convective treatmentASIA-PACIFIC JOURNAL OF CHEMICAL ENGINEERING, Issue 2 2007Gábor Bihercz Abstract Drying is a necessary technology and a very energy-demanding process in the area of meat and vegetable processing; it is a tool for finishing semiprocessed or processed goods. Taking the given conditions into consideration, development of technology is necessary, which serves several aims that are often in disagreement with each other (in terms of improvement of availability value, avoidance of artificial additives, energy optimization, reduction of other cost factors, etc.). Until now, several scientific works have been published serving solutions for one specific problem of practice. The main idiosyncrasy of these works is the difference between their methods and availability; hence these are unsuitable to give a uniform model for products with different physical-biological properties: because, it goes without saying, circumstances of their birth as well as their aims differ so much. Computer support nowadays allows us to build a uniform model based on previous research and auxiliary measurement results, which can simulate the drying process of some of the most important agricultural products.
