Selected AbstractsEnglish University Benefactors in the Middle AgesHISTORY, Issue 283 2001Alan B. Cobban The medieval universities of Oxford and Cambridge owed an enormous debt to the generosity of a plurality of benefactors of diverse social origins. Given their limited incomes, the universities could not have functioned at a successful level without the substantial material aid of benefactors. Although the English monarchy made a valuable contribution to several areas of university and collegiate life, it nevertheless appears that this monarchical beneficence was less extensive than might have been supposed. The English male nobility gave the occasional gift of property and made donations to loan-chests but before 1500 only one nobleman was a principal founder of a secular academic college. This opened the way for queens consort and female members of the greater aristocracy to emerge as significant benefactresses in both the university and collegiate spheres. Indeed, it could be argued that women from the upper echelons of society came to rank in importance as university and college benefactors with lesser ecclesiastics, knights, burgesses, merchants, current and former members of colleges and university servants. However, taking the donations of the episcopate in the round, it is probably true to say that the English bishops made the most decisive contribution [source] The informant questionnaire on cognitive decline in the elderly (IQCODE) is associated with informant stressINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 11 2009Harald A. Nygaard Abstract Objective To study the association between informant stress and appraisal of patients' cognitive functioning as reported by the Informant Questionnaire on Cognitive Decline in the Elderly,IQCODE. Methods Routinely collected data from a geriatric outpatient department (207 dyads) during the years 1995,1998 were analysed. Relative stress scale (RSS) has been categorised for possible low, intermediate and high risk of psychiatric morbidity and caregivers were combined to four groups (female and male spouses and female and male non-spouses, respectively). The relationship between IQCODE (dependent) and categorised RSS and informant groups and patient age was further studied by means of the general linear model (GLM,UNIANOVA). Results In general, spouses reported better cognitive functioning than non-spouses. There was a significant association between IQCODE and RSS (p,<,0.001), and the composite variable informant group and informant gender (p,<,0.001). The main effect of the interaction term RSS,×,informant group,+,informant gender was not significant. Post hoc test, however, revealed a significant effect of the interaction term RSS,×,female spouses (p,<,0.001) on IQCODE. Conclusion IQCODE is associated with informant stress. Categorisation of RSS score into groups of low, intermediate and high risk for psychiatric morbidity can be a valuable contribution to a more meaningful application of RSS in general practice.

Freezing temperature significantly influenced each of the characteristics studied. High temperatures (,10 and,25C) gave increased thaw exudates, and freezing at,10C gave the highest liquid leakage during freeze-chilling. Fillets frozen at,10C had the lowest gaping and the whitest appearance. The results indicated the highest degree of toughening upon freezing at,10 or,55C, whereas the degree of toughening appeared to be similar and lower for fillets frozen at,25,,40 or,70C. The impact of freezing temperatures on the quality of farmed cod therefore appeared to be complex, but no overall beneficial effects were found by decreasing the freezing temperature below,40C. PRACTICAL APPLICATIONS For the fish processing industry, it is important to define optimal freezing and frozen storage regimes that are cost efficient and at the same time preserve the fresh fillet quality. Farmed cod differ from their wild counterparts by having lower water content, lower muscle pH and thicker fillets. Hence, industrial guidelines for wild cod may not be transferable to farmed cod. This study showed no beneficial effects by decreasing the freezing temperature below ,40C. Freezing and frozen storage are usually separated commercially. Results from the present study give valuable contribution to future studies aiming at defining optimal combination of freezing and frozen storage temperatures for farmed Atlantic cod. [source] The economics of soil productivity: local, national and global perspectivesLAND DEGRADATION AND DEVELOPMENT, Issue 6 2004D. J. Knowler Abstract Soil degradation is a mounting problem on many smallholder lands in developing countries. Economic analysis has been an important tool in addressing this problem, beginning with assessments of the financial attractiveness of investing in soil conservation works. Data compiled from 67 studies of the financial attractiveness of conservation technologies suggest that many can provide positive net returns at the farm level (64·2,per,cent). While such studies have made a valuable contribution, economists have been exploring additional applications of economics to the problem, such as the development of new perspectives under the guise of ecological economics. As a result, this paper argues it is an opportune time to assess progress in the field of economic analysis of soil degradation and to consider the policy ramifications of this research. Key issues are grouped into farm-level considerations, national policy linkages and global issues. A number of policy implications emerge. Clearly, devising effective incentives at the farm or community (collective action) level must be a priority. As part of this effort, even more attention should be paid to the influence of macroeconomic and sectoral policies on soil productivity. Since soil degradation is also a problem with global ramifications, there is a clear rationale for intervention at the international level via mechanisms such as international transfers.

[source] Cryptic diversity and patterns of host specificity in trematode flatwormsMOLECULAR ECOLOGY, Issue 13 2010ALEXANDER HAYWARD The widespread utilization of molecular markers has revealed that a broad spectrum of taxa contain sets of morphologically cryptic, but genetically distinct lineages (Bickford et al. 2007). The identification of cryptic taxa is important as an accurate appreciation of diversity is crucial for a proper understanding of evolutionary and ecological processes. An example is the study of host specificity in parasitic taxa, where an apparent generalist may be found to contain a complex of several more specific species (Smith et al. 2006). Host specificity is a key life history trait that varies greatly among parasites (Poulin & Keeney 2007). While some can exploit a wide range of hosts, others are confined to just a single species. Access to additional hosts increases the resources available to a parasite. However, physiological or ecological constraints can restrict the extension of host range. Furthermore, there may be a trade-off between relaxed specificity and performance: generalism can decrease a parasites ability to adapt to each individual host species, and increase exposure to competition from other parasites (Poulin 1998). Despite the central role that host specificity plays in parasite life history, relatively little is known about how host range is determined in natural systems, and data from field studies are required to evaluate among competing ideas. In this issue, an exciting paper by Locke et al. (2010) makes a valuable contribution toward the understanding of host specificity in an important group of trematode flatworms. Using molecular methods, Locke et al. reveal an almost four-fold increase in the appreciated diversity of their focal group. In combination with a large and elegant sampling design this allows them to accurately assess host specificity for each taxon, and thus draw key insights into the factors that control host range in a dominant parasite group. [source] Occupational therapy adaptation of the home environment in Sweden for people with asthmaOCCUPATIONAL THERAPY INTERNATIONAL, Issue 4 2002Doctoral Candidate, Margot Frisk Occupational Therapist Abstract The purpose of this study was to evaluate changes of lung function, respiratory symptoms and indoor air quality after reducing allergens and indoor pollutants in the home environment of people with asthma (n = 21). A quasi-experimental pre-/post-test design with one group of participants was implemented. The interventions included removal of wall-to-wall carpets (n = 14) or improvement of indoor air exchange (n = 7). Participants' lung function, symptoms, medication and type-1 allergy were recorded before and after the intervention. The indoor environment was monitored at house calls by an occupational therapist using conventional physical, biological and chemical methods. There was an improvement of lung function evidenced by an increased mean Forced Expiratory Volume (FEV1 %) and a reduction of airway obstruction (reversibility, % of baseline value), which indicate an improved asthmatic condition. Lung function assessed by vital capacity, bronchial hyper-responsiveness, mean of Peak Expiratory Flow, symptom score and medicine consumption did not change significantly. There was a tendency that the amount of airborne dust (p=0.06) was reduced in the indoor environment. Relative humidity, carbon dioxide, formaldehyde and house dust mite levels had decreased after the intervention, but not significantly. Asthma symptoms related to the home environment are probably caused by several factors. When people with asthma suffer from increased symptoms in the home, house calls should be performed routinely. Dust samples from beds and carpets for analysis of allergens give information about exposure, and environmental assessments should be performed before interventions. Occupational therapists can make a valuable contribution in evaluating the home environment and suggesting ergonomic adaptations for individuals with asthma. Copyright © 2002 Whurr Publishers Ltd. [source] In Vitro Sunscreen Transmittance Measurement with Concomitant Evaluation of Photostability: Evolution of a MethodPHOTOCHEMISTRY & PHOTOBIOLOGY, Issue 4 2009Robert M. Sayre The recent paper by Miura et al. (Photochem. Photobiol. 84[6], 1569,1575) offers a re-examination of extant in vitro methods for dynamically measuring sunscreen photodegradation under continuous irradiation in situ. We commend the authors' efforts toward developing an improved system for accurate in vitro sunscreen assessment. This work describes an alternate derivative apparatus incorporating an improved detector which may prove an exceptionally valuable contribution toward that goal. Unfortunately their report suffers from insufficient detail in instrumentation description and lacks requisite calibration procedures. Their utilization of a solar simulator filtered for conventional in vivo sun protection factor (SPF) testing poses transmittance measurement limitations at short wavelengths that are not adequately addressed and is also deficient, relative to sunlight, in longer UVA wavelengths shown to contribute to sunscreen photoinstability. We concur that the in vitro sunscreen testing should utilize continuous or multiple irradiation doses and should ideally use the same 2 mg cm,2 product application amount as does the human SPF test. We encourage their proposal that methodology, which simultaneously measures sunscreen spectral transmittance and photodegradation under continuous irradiation to an accumulated erythemic endpoint, as we previously described, be developed into a consensus test standard. [source] Enzyme and acid treatment of fish meal for incorporation into formulated microbound diets for barramundi (Lates calcarifer) larvaeAQUACULTURE NUTRITION, Issue 2 2009L. NANKERVIS Abstract This study reports on two experiments in which the use of enzyme- and acid-treated fish meal were evaluated for incorporation into formulated microbound diets for barramundi (Lates calcarifer) larvae. In the first experiment, partially hydrolysed fish meal was used to determine whether partial hydrolysis increased the dietary value of fish meal used in microbound diets fed to L. calcarifer larvae. Total length and dry weight at the end of the experiment were both higher for larvae fed diets containing untreated fish meal than those fed diets containing any level of hydrolysate. Larval survival ranged from 15.8% to 47.2% but there were no significant differences between treatments (Fig. 3; P > 0.05). Carcass pepsin levels of larvae fed diets containing untreated fish meal were significantly higher than pepsin levels of larvae fed all other diets (P < 0.05). The second experiment determined the effects of incorporating graded levels of denatured fish meal (DF) into microbound diets for L. calcarifer larvae. Acid treatment increased the digestibility of fish meal approximately twofold when compared with intact fish meal. Larvae fed diets containing 45% DF had significantly higher total length and dry weight at the end of the growth trial than those fed a diet containing only intact fish meal. Larval survival ranged from 30.2% to 58.2%, with no significant differences between treatments. Whole homogenate pepsin levels were significantly affected by the level of dietary DF inclusion with larvae fed diets containing a greater proportion of intact fish meal containing higher pepsin levels. There was a significant correlation between dietary DF inclusion level and decreasing pepsin level (r2 = 0.569, P < 0.01); however, larval pepsin level did not correlate to either dry weight or total length (Pearson correlation, P > 0.05). The results of this study are a valuable contribution to our understanding of factors influencing the utilization of ingredients in microbound diets developed for marine fish larvae and will facilitate development of more effective formulated foods for them. Figure 3. ,Mean (±SE) survival of barramundi larvae fed experimental diets containing fish meal hydrolysed for varying period (7.5,60 min), from 14 to 28 days after hatching. Means with different superscripts are significantly different (P < 0.05). [source] Lactic acid bacteria vs. pathogens in the gastrointestinal tract of fish: a reviewAQUACULTURE RESEARCH, Issue 4 2010Einar Ringø Abstract Intensive fish production worldwide has increased the risk of infectious diseases. However, before any infection can be established, pathogens must penetrate the primary barrier. In fish, the three major routes of infection are the skin, gills and gastrointestinal (GI) tract. The GI tract is essentially a muscular tube lined by a mucous membrane of columnar epithelial cells that exhibit a regional variation in structure and function. In the last two decades, our understanding of the endocytosis and translocation of bacteria across this mucosa, and the sorts of cell damage caused by pathogenic bacteria, has increased. Electron microscopy has made a valuable contribution to this knowledge. In the fish-farming industry, severe economic losses are caused by furunculosis (agent, Aeromonas salmonicida spp. salmonicida) and vibriosis [agent, Vibrio (Listonella) anguillarum]. This article provides an overview of the GI tract of fish from an electron microscopical perspective focusing on cellular damage (specific attack on tight junctions and desmosomes) caused by pathogenic bacteria, and interactions between the ,good' intestinal bacteria [e.g. lactic acid bacteria (LAB)] and pathogens. Using different in vitro methods, several studies have demonstrated that co-incubation of Atlantic salmon (Salmo salar L.) foregut (proximal intestine) with LAB and pathogens can have beneficial effects, the cell damage caused by the pathogens being prevented, to some extent, by the LAB. However, there is uncertainty over whether or not similar effects are observed in other species such as Atlantic cod (Gadus morhua L.). When discussing cellular damage in the GI tract of fish caused by pathogenic bacteria, several important questions arise including: (1) Do different pathogenic bacteria use different mechanisms to infect the gut? (2) Does the gradual development of the GI tract from larva to adult affect infection? (3) Are there different infection patterns between different fish species? The present article addresses these and other questions. [source] Learning from Difference: Considerations for Schools as CommunitiesCURRICULUM INQUIRY, Issue 3 2000Carolyn M. Shields In today's highly complex and heterogeneous public schools, the current notion of schools as homogeneous communities with shared beliefs, norms, and alues is inadequate. Drawing on Barth's (1990) question of how to use ifference as a resource, I take up ideas from feminism, multiculturalism, and inclusive education to consider the development of community in schools. I argue that despite the valuable contributions of these theoretical perspectives, each lso includes the potential for increased fragmentation and polarization. As we consider how to use differences as a foundation for community, it is important ot to reify any particular perspective, thus marginalizing others and erecting new barriers. Explicitly embracing the need to identify and respect difference, being open to new ideas without taking an exclusionary position, and committing to ongoing participation in dialogical processes may help schools to develop as more authentic communities of difference. Among the dominant issues identified in today's climate of turbulent educational reform are concerns about how to restructure schools to ensure equality of student opportunity and excellence of instruction (Elmore, 1990; Lieberman, 1992; Murphy, 1991). Many proposals include modifying present leadership and governance structures, overcoming the hegemony of existing power bases, developing mechanisms for accountability, enhancing professionalism, and co-ordinating community resources. One of the suggestions frequently made to address these issues is to change from a focus on schools as organizations to a recognition of schools as communities (Barth, 1990; Fullan, 1993; Lupart & Webber, 1996; Senge, 1990). However, despite the widespread use of the metaphor of community as an alternative to the generally accepted concept of schools as rational or functional organizations, there seems to be little clarity about the concept of community, what it might look like, how it might be implemented, or what policies might sustain it. Indeed, theories about schools as communities have often drawn from Tönnies (1887/1971) concept of gemeinschaft,a concept which perhaps evokes a more homogeneous and romanticized view of the past than one which could be helpful for improving education in today's dynamic, complex, and heterogeneous context (Beck & Kratzer, 1994; Sergiovanni, 1994a). More recently, several writers (Fine et al., 1997; Furman, 1998; Shields & Seltzer, 1997) have advanced the notion of communities of otherness or difference. These authors have suggested that rather than thinking of schools as communities that exist because of a common affiliation to an established school ethos or tradition, it might be more helpful to explore an alternative concept. A school community founded on difference would be one in which the common centre would not be taken as a given but would be co-constructed from the negotiation of disparate beliefs and values as participants learn to respect, and to listen to, each other. In this concept, bonds among members are not assumed, but forged, and boundaries are not imposed but negotiated. Over the past eight years, as I have visited and worked with a large number of schools trying earnestly to address the needs of their diverse student bodies, I have become increasingly aware of the limitations of the concept of community used in the gemeinschaft sense with its emphasis on shared values, norms, and beliefs, and have begun to reflect on the question framed by Barth (1990): ,How can we make conscious, deliberate use of differences in social class, gender, age, ability, race, and interest as resources for learning?' (p. 514). In this article, I consider how learning from three of these areas of difference: gender, race, and ability, may help us to a better understanding of educational community. This article begins with some illustrations and examples from practice, moves to consider how some theoretical perspectives may illuminate them, and concludes with reflections on how the implications of the combined reflections on practice and theory might actually help to reconceptualize and to improve practice. While it draws heavily on questions and impressions which have arisen out of much of my fieldwork, it is not intended to be an empirical paper, but a conceptual one,one which promotes reflection and discussion on the concept of schools as communities of difference. The examples of life in schools taken from longitudinal research studies in which I have been involved demonstrate several common ways in which difference is dealt with in today's schools and some of the problems inherent in these approaches. Some ideas drawn from alternative perspectives then begin to address Barth's question of how to make deliberate use of diversity as a way of thinking about community. Taken together, I hope that these ideas will be helpful in creating what I have elsewhere called ,schools as communities of difference' (Shields & Seltzer, 1997). [source] Twenty years of external quality assurance in clinical cell analysis , A tribute to Jean-Luc D'HautcourtCYTOMETRY, Issue 1 2007Bruno Brando Abstract External quality assurance (EQA) programs in clinical cell analysis are now a consolidated item of laboratory practice. All the flow cytometric testings with an impact on clinical decision making have been submitted to regular EQA programs during the last 20 years, and this has produced internationally homogeneous guidelines, with a remarkable improvement in result reproducibility. Jean-Luc D'Hautcourt was a pioneer in this field, and his valuable contributions to flow cytometric method standardization and to the dissemination of the educational aspects of EQA programs are recognized. The different methodological approaches undertaken in the United States and Europe are discussed. The educational role of SIHON in the Benelux Countries and of UKNEQAS for Leucocyte Immunophenotyping worldwide is emphasized. Accredited and accreditating EQA programs require an impressive degree of organization and technical knowledge, so that only major international providers can afford such a task nowadays. However, small local studies still provide the necessary stimulus to the continuous improvement of the scientifical aspects of EQA schemes. © 2006 Clinical Cytometry Society [source] Honoring the Admiral: Boerhaave-van Wassenaer's syndromeDISEASES OF THE ESOPHAGUS, Issue 3 2006B. D. Adams SUMMARY., Dr. Herman Boerhaave (1668,1738) first described esophageal rupture and the subsequent mediastinal sepsis based upon his careful clinical and autopsy findings and hundreds of references have since been written about Boerhaave's syndrome. Several fine historical accounts of this brilliant scientist have been published over the years and he has received appropriate credit for his valuable contributions. But what about that unfortunate propositus that Dr. Boerhaave attended to, performed necropsy upon, and subsequently received acclaim with? Medical history pays inadequate regard to the Baron Jan Gerrit van Wassenaer heer van Rosenberg, Prefect of Rhineland and Grand Admiral of the Dutch Fleet. This figure was a nobleman and war hero at the peak of the Dutch Golden Age who played his role in steering the course of European history. Without this nobleman's heroic contemporaneous account, Boerhaave's celebrated impact on medical science would never have been realized. Therefore, we offer an overdue recitation of Admiral van Wassenaer's biography. Based on found precedent we propose that spontaneous rupture of the esophagus be henceforth referred to as the ,Boerhaave-van Wassenaer's syndrome'. [source] Partners in treatment: relational psychoanalysis and harm reduction therapyJOURNAL OF CLINICAL PSYCHOLOGY, Issue 2 2010Debra Rothschild Abstract A relational psychoanalytic harm reduction orientation to the treatment of substance misusers is presented and illustrated with a clinical example. Both harm reduction therapy and relational psychoanalysis rely on a two-person model in which the therapist and client are collaborators in the treatment. In both, substance use is seen in the context of the user's internal psychodynamics and external environment, and there is an emphasis on treating the person as a whole individual whose substance use is one aspect of life, rather than focusing on the substance use itself as was often done in the past. Historically, psychoanalysis and substance abuse treatment were so different from each other that their paths rarely crossed. The introduction of harm reduction therapy to substance abuse and the relational orientation in psychoanalysis have brought the fields closer together such that the valuable contributions that each can make to the other can now be appreciated. © 2010 Wiley Periodicals, Inc.

[source] Religion, Politics and Civic EducationJOURNAL OF PHILOSOPHY OF EDUCATION, Issue 1 2005Robert Kunzman The proper role and influence of religion in the public sphere continues to be contested and has important implications for civic education in a liberal democracy. Paul Weithman and Michael Perry argue that religion makes valuable contributions to civic participation and that religiously grounded beliefs should be fully welcome in political decision-making. In response, this paper strives for a middle ground of preparing citizens to engage thoughtfully with a wide range of moral perspectives, religious and otherwise, while promoting a civic virtue that still honours a commitment to public reason.

(c) 1/9PHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 9 2004Andrew Leitch The Conference on Photo-responsive Materials took place at the Kariega Game Reserve in the Eastern Cape, South Africa from 25,29 February 2004. More than 60 delegates from 12 different countries participated in the four-day event. The purpose of the conference was to bring together scientists working on various aspects of photo-responsive materials, so as to stimulate this important field of solid state physics in Southern Africa. As may be seen from the list of papers appearing in these proceedings, there was much interest in copper indium diselenide as a thin film material for photovoltaic applications. Also worth mentioning were the valuable contributions on ZnO, GaN and other materials that are currently attracting attention worldwide. The conference program allowed sufficient time for interaction and exchanging of views. Being in a game reserve in the heart of the beautiful Eastern Cape, delegates were also taken on game drives and had the opportunity of taking a river cruise up the Kariega River to view the majestic fish eagle. The members of the academic program committee were: Vivian Alberts (Rand Afrikaans University), Danie Auret (University of Pretoria), Darrell Comins (University of the Witwatersrand), and Reinhardt Botha and Andrew Leitch (University of Port Elizabeth). All papers appearing in these proceedings underwent a strict reviewing process separate from the conference. We express our appreciation to the referees for their diligence in this important task. The conference was organized by the Department of Physics at the University of Port Elizabeth, under the auspices of the Condensed Matter Physics and Materials Science (CMPMS) subgroup of the South African Institute of Physics. It was sponsored by EMF Limited (UK), Sensors Unlimited Inc. (USA), and Carl Zeiss (Pty) Ltd.

Frank Abstract: The moss Physcomitrella patens has become a suitable model plant system for the analysis of diverse aspects of modern plant biology. The research strategies have been influenced by the implementation of state-of-the-art cell culture and molecular biology techniques. The forthcoming completion of the Physcomitrella genome sequencing project will generate many open questions, the examination of which will rely on a diverse set of molecular tools. Within this article, we intend to introduce the essential cell culture and molecular biology techniques which have been adopted in recent years to make Physcomitrella amenable to a wide range of genetic analyses. Many research groups have made valuable contributions to improve the methodology for the study of Physcomitrella.
