Keeping the Vermin Out: Perceived Disease Threat and Ideological Orientations as Predictors of Exclusionary Immigration Attitudes

Integrating evolutionary and social representations theories, the current study examines the relationship between perceived disease threat and exclusionary immigration attitudes in the context of a potential avian influenza pandemic. This large-scale disease provides a realistic context for investigating the link between disease threat and immigration attitudes. The main aim of this cross-sectional study (N=412) was to explore mechanisms through which perceived chronic and contextual disease threats operate on immigration attitudes. Structural equation models show that the relationship between chronic disease threat (germ aversion) and exclusionary immigration attitudes (assimiliationist immigration criteria, health-based immigration criteria and desire to reduce the proportion of foreigners) was mediated by ideological and normative beliefs (social dominance orientation, belief in a dangerous world), but not by contextual disease threat (appraisal of avian influenza pandemic threat). Contextual disease threat only predicted support for health-based immigration criteria. The conditions under which real-life disease threats influence intergroup attitudes are scrutinized. Convergence and dissimilarity of evolutionary and social representational approaches in accounting for the link between disease threat and immigration attitudes are discussed.

Patient expectations at a multicultural out-patient clinic in Switzerland.

BACKGROUND: Recognizing patient expectation is considered as an important objective for primary care physicians. A number of studies suggest that failure to identify patient expectations can lead to patient dissatisfaction with care, lack of compliance and inappropriate use of medical resources. It has been suggested that identifying patient expectations in multicultural contexts can be especially challenging. OBJECTIVES: The aim of the study was to compare health care expectations of Swiss and immigrant patients attending the out-patient clinic of a Swiss university hospital and to assess physicians' ability to identify their patients' expectations. METHODS: Over a 3-month period, all patients attending the out-patient clinic at a Swiss university hospital were requested to complete pre-consultation surveys. Their physicians were requested to complete post-consultation surveys. Outcome measures were patients' self-rated health, resort to prior home treatment, patients' expectations of the consultation, physicians' perception of their patients' expectations and agreement between patients and physicians. RESULTS: We analysed 343 questionnaires completed by patients prior to their consultation (> 50% immigrants) and 333 questionnaires completed by their physicians after the consultation. Most expectations were shared by all patients. Physicians had inaccurate perceptions of their patients' expectations, regardless of patients' origin. CONCLUSIONS: Our study found no evidence that immigrant patients' expectations differed from those of Swiss patients, nor that physicians had more difficulty identifying expectations of immigrant patients. However, physicians in our study were generally poor at identifying patients' expectations, and therefore inter-group differences may be difficult to detect. Our results point to the need to strengthen physicians' general communication skills which should then serve as a foundation for more specific, cross-cultural communication training.

Accuracy of out-of-field dose calculation of tomotherapy and cyberknife treatment planning systems: A dosimetric study.

PURPOSE: Late toxicities such as second cancer induction become more important as treatment outcome improves. Often the dose distribution calculated with a commercial treatment planning system (TPS) is used to estimate radiation carcinogenesis for the radiotherapy patient. However, for locations beyond the treatment field borders, the accuracy is not well known. The aim of this study was to perform detailed out-of-field-measurements for a typical radiotherapy treatment plan administered with a Cyberknife and a Tomotherapy machine and to compare the measurements to the predictions of the TPS. MATERIALS AND METHODS: Individually calibrated thermoluminescent dosimeters were used to measure absorbed dose in an anthropomorphic phantom at 184 locations. The measured dose distributions from 6 MV intensity-modulated treatment beams for CyberKnife and TomoTherapy machines were compared to the dose calculations from the TPS. RESULTS: The TPS are underestimating the dose far away from the target volume. Quantitatively the Cyberknife underestimates the dose at 40cm from the PTV border by a factor of 60, the Tomotherapy TPS by a factor of two. If a 50% dose uncertainty is accepted, the Cyberknife TPS can predict doses down to approximately 10 mGy/treatment Gy, the Tomotherapy-TPS down to 0.75 mGy/treatment Gy. The Cyberknife TPS can then be used up to 10cm from the PTV border the Tomotherapy up to 35cm. CONCLUSIONS: We determined that the Cyberknife and Tomotherapy TPS underestimate substantially the doses far away from the treated volume. It is recommended not to use out-of-field doses from the Cyberknife TPS for applications like modeling of second cancer induction. The Tomotherapy TPS can be used up to 35cm from the PTV border (for a 390 cm(3) large PTV).

Introducción a la farmacia galénica: un reto en primer año de farmacia

[spa] Este curso académico 2009-2010 se implanta el nuevo plan de estudios de Farmacia en la Universidad de Barcelona, diseñado según los planteamientos del EEES. Como consecuencia, y por primera vez en la historia de la Facultad de Farmacia de la UB, se imparte una asignatura troncal de cariz galénico en el primer año de la carrera. Esto constituye un nuevo reto para el Grupo de Innovación Docente de Tecnología Farmacéutica (GIDTF), dado que la asignatura Introducción a la Farmacia Galénica se ha de impartir a grandes grupos de estudiantes, al inicio de su carrera, mediante sesiones teóricas de 1,5 h. Excepcionalmente en este curso académico, la asignatura se imparte en el primer semestre y se repite en el segundo. En este trabajo se presenta el planteamiento metodológico presencial diseñado para esta asignatura, apoyado en estrategias no presenciales como foro de debate, recursos on-line, cuestionarios y tareas de autoevaluación a través de la plataforma Moodle del Campus Virtual de la UB, puesto que el equipo docente considera prioritario iniciar al estudiante en el uso de la misma en el primer año de carrera. Se han efectuado encuestas de satisfacción a los estudiantes que se han evaluado, así también como los resultados académicos obtenidos. En el análisis de los puntos fuertes y débiles de la metodología empleada, se han detectado evaluaciones positivas y también aspectos que podrían mejorarse, estableciendo las medidas correctoras adecuadas. En cuanto a los resultados académicos, han sido muy satisfactorios. [eng] This academic year 2009-2010, the new curriculum of Pharmacy according to the premises of the EHEA is started at the University of Barcelona. As a result, for the first time in the history of the Faculty of Pharmacy of UB, an obligatory galenic subject will be given during the first year of the career. This is a new challenge for Teaching Innovation Group of Pharmaceutical Technology (GIDTF), as the subject Introduction to Galenic Pharmacy is given by a team of teachers to large groups of students who began its career, through theoretical sessions of 1.5 h. The subject will be taught exceptionally this academic year in the first semester and repeated in the second. In this paper we present the methodological approach designed to face this subject, supported by virtual strategies as discussion forum, online resources, self-assessment test and work through the platform Moodle of the Virtual Campus UB, as the team considers it a priority to initiate the student in using it in the first year of pharmacy study. Were carried out satisfaction surveys to students and we have evaluated them, as well as academic performance. Through the analysis of the methodology, we detected positive evaluations and areas for improvement that have been used to establish appropriate corrective measures. Academic results have been very satisfactory.

On the relationship between performance-approach goals and cognitive performance : when the desire to outperform others becomes interfering

Cette thèse explore dans quelle mesure la poursuite d'un but de performance-approche (i.e., le désir de surpasser autrui et de démontrer ses compétences) favorise, ou au contraire endommage, la réussite et l'apprentissage-une question toujours largement débattue dans la littérature. Quatre études menées en laboratoire ont confirmé cette hypothèse et démontré que la poursuite du but de performance-approche amène les individus à diviser leur attention entre d'une part la réalisation de la tâche évaluée, et d'autre part la gestion de préoccupations liées à l'atteinte du but-ceci empêchant une concentration efficace sur les processus de résolution de la tâche. Dans une deuxième ligne de recherche, nous avons ensuite démontré que cette distraction est exacerbée chez les individus les plus performants et ayant le plus l'habitude de réussir, ceci dérivant d'une pression supplémentaire liée au souhait de maintenir le statut positif de « bon élève ». Enfin, notre troisième ligne de recherche a cherché à réconcilier ces résultats-pointant l'aspect distractif du but de performance-approche-avec le profil se dégageant des études longitudinales rapportées dans la littérature-associant ce but avec la réussite académique. Ainsi, nous avons mené une étude longitudinale testant si l'adoption du but de performance-approche en classe pourrait augmenter la mise en oeuvre de stratégies d'étude tactiquement dirigées vers la performance-favorisant une réussite optimale aux tests. Nos résultats ont apporté des éléments en faveur de cette hypothèse, mais uniquement chez les élèves de bas niveau. Ainsi, l'ensemble de nos résultats permet de mettre en lumière les processus cognitifs à l'oeuvre lors de la poursuite du but de performance-approche, ainsi que d'alimenter le débat concernant leur aspect bénéfique ou nuisible en contexte éducatif. -- In this dissertation, we propose to investigate whether the pursuit of performance-approach goals (i.e., the desire to outperform others and appear talented) facilitates or rather endangers achievement and learning-an issue that is still widely discussed in the achievement goal literature. Four experiments carried out in a laboratory setting have provided evidence that performance- approach goals create a divided-attention situation that leads cognitive resources to be divided between task processing and the activation of goal-attainment concerns-which jeopardizes full cognitive immersion in the task. Then, in a second research line, we found evidence that high- achievers (i.e., those individuals who are the most used to succeed) experience, under evaluative contexts, heightened pressure to excel at the task, deriving from concerns associated with the preservation of their "high-achiever" status. Finally, a third research line was designed to try to reconcile results stemming from our laboratory studies with the overall profile emerging from longitudinal research-which have consistently found performance-approach goals to be a positive predictor of students' test scores. We thus set up a longitudinal study so as to test whether students' adoption of performance-approach goals in a long-term classroom setting enhances the implementation of strategic study behaviors tactically directed toward goal-attainment, hence favoring test performance. Our findings brought support for this hypothesis, but only for low-achieving students. Taken together, our findings shed new light on the cognitive processes at play during the pursuit of performance-approach goals, and are likely to fuel the debate regarding whether performance-approach goals should be encouraged or not in educational settings.

Dissociation from BiP and Retrotranslocation of Unassembled Immunoglobulin Light Chains Are Tightly Coupled to Proteasome Activity

Unassembled immunoglobulin light chains expressed by the mouse plasmacytoma cell line NS1 (KNS1) are degraded in vivo with a half-life of 50-60 min in a way that closely resembles endoplasmic reticulum (ER)-associated degradation (Knittler et al., 1995). Here we show that the peptide aldehydes MG132 and PS1 and the specific proteasome inhibitor lactacystin effectively increased the half-life of KNS1, arguing for a proteasome-mediated degradation pathway. Subcellular fractionation and protease protection assays have indicated an ER localization of KNS1 upon proteasome inhibition. This was independently confirmed by the analysis of the folding state of KNS1and size fractionation experiments showing that the immunoglobulin light chain remained bound to the ER chaperone BiP when the activity of the proteasome was blocked. Moreover, kinetic studies performed in lactacystin-treated cells revealed a time-dependent increase in the physical stability of the BiP-KNS1complex, suggesting that additional proteins are present in the older complex. Together, our data support a model for ER-associated degradation in which both the release of a soluble nonglycosylated protein from BiP and its retrotranslocation out of the ER are tightly coupled with proteasome activity.

Central line sepsis in intensive care units : overview and update

Catheter-related infection remains a leading cause of nosocomial infections, particularly in intensive care units. It includes colonization of the device, skin exit-site infection and device- or catheter-related bloodstream infection. The latter represents the most frequent life-threatening associated complication of central venous catheter use and is associated with significant patient morbidity, mortality and extra hospital costs. The incidence of catheter-related bloodstream infection ranges from 2 to 14 episodes per 1000 catheter-days. On average, microbiologically-documented device-related bloodstream infections complicate from three to five per 100 central venous line uses, but they only represent the visible part of the iceberg and most clinical sepsis are nowadays considered to be catheter-related. We briefly review the pathophysiology of infection, highlighting the importance of the skin insertion site and of intravenous line hub as principal sources of colonization. Principles of therapy are reviewed. Several preventive approaches are also discussed, in particular the possible benefit of recently developed impregnated catheters. Finally, the potential positive impact of a multimodal global preventive strategy based on strict application of hygienic rules is presented.

Phytochemical investigation of alpine plants : the cottonsedges Eriophorum scheuchzeri Hoppe, E. angustifolium Honck. and E. latifolium Hoppe (CYPERACEAE)

Résumé: Alpine plants living at high altitudes undergo a series of climatic stress factors (chilling, enhanced UV radiation, short growing season, low nutriment supply...) which may influence their secondary compounds composition. Many publications showed in these last years that plants under stress conditions do synthesize a range of specific defence compounds (terpenes, flavonoids, coumarines...). A careful phytochemical investigation of those plants could therefore lead to the discovery of active molecules. Thus, for the biological and chemical screening, about 30 alpine plants have been collected above 2000 metres, in the alpine grass-lands. Eriophorum scheuchzeri Hoppe (Cyperaceae), not yet investigated phytochemically, revealed in its lipophilic and polar extracts the presence of various radical scavengers in a TLC autography with the DPPH (2,2-dipheny1-1- picrylhydrazyl) radical as spray reagent, as well as several antifungal compounds acitve against Cladosporium cucumerinum and Candida albi cans. The first part of this study consisted in the detection, isolation and characterization of the bioactive natural compounds present in the lipophilic extract of Eriophorum scheuchzeri. Among the eight isolated compounds, six were isoflavones. No isoflavones have been reported in the Cyperaceae family yet, nor in related families such as Poaceae or Juncaceae. Besides, isoflavones are generally rare in the plant kingdom and and they occur only in some families, such as Fabaceae, Rosaceae or Myristicaceae. In addition, out of these six isoflavones, three were new isoflavones. The known compounds were parvisoflavone A and B and cajanin which are already known isoflavones in the Fabaceae family. Two of the new isoflavones were particular, as they were C-methylated on the B-ring at the C-3' position. Methylated flavonoids are particularly rare in the plant kingdom. At present, no C-methylated isoflavones with methyl groups on the B-ring have ever been reported. The fourth new compound was a prenylated flavanone. Flavanones are also rare in the Cyperaceae family since they were found only in two genera (Cyperus and Schoenus). Finally, the widespread flavone tricin, characteristic of the Cyperaceae and Poaceae family has also been isolated. The second part of this study consisted in the characterization of the polar components present in the Me0H extract. In order to obtain mass and UV information about the secondary compounds present in the Eriophorum scheuchzeri methanolic extract, a LC-UV/DAD-APCl/MSn analysis has been performed as a first dereplication step. The UV/DAD spectra showed the presence of polyphenol compounds (phenylpropanoids and flavonoids). The LC-APCI/MSn analysis allowed the determination of the molecular weight of these compounds. Moreover, the fragmentation pattern of the [M+H]+ ions indicated presence of mono-, di- and tri-glycosides. LC-UV in combination with UV shift reagents added post-column was used in a second phase for the structural elucidation of the flavonoids. It allowed the positioning of the sugars on the aglycones. Finally, LC-NMR was used for a more detailed structural investigation of the compounds present in the crude MEOH extract. Thus, 10 fiavonoids have been totally or partially characterized by LC-UV-MS and LC-1H-RMN and UV-shift reagents added post column. However, the information obtained on-line was not always sufficient to allow a complete identification of all the compounds. Some of these compounds especially those with more than two sugar units attached to them, have been isolated in order to proceed to their complete characterization. Moreover, the Eriophorum scheuchzeri species was compared to two other species from the same genus. A LC-UV-ESI/MS analysis enabled a survey of the chemical composition of the DCM extracts of two related species E. angustifolium (Honck) and E. latifolium (Hoppe). The chromatograms of the three species showed some similarities in their flavonoid contents, especially by the recurrent presence of three compounds. The MEOH extracts of all three species have been compared by means of LC-UV-APCl/MS analyses. The chromatographic profile of all the three species showed even closer similarities than those found in the DCM extracts. E. angustifolium Honck. and E. latifolium species showed 7 compounds in common. Finally, the pure compounds obtained from the DCM (CH2Cl2) fraction were tested at different concentration, in order to evaluate their chemical and biological activities. All eight compounds showed an anti-scavenger activity against the DPPH radical, and four compounds showed antifungal activities against Cladosporium cucumerinum and Candida albicans. The pure compounds isolated from the MeOH extract were tested only for their biological activities as their antioxidant activity is already well documented in the literature. No compound showed a biological activity against Cladosporium cucumerinum and Candida albicans. Résumé: De nombreux travaux ont démontré ces dernières décennies que les plantes soumises à différents types de stress (basse température, UV, stress hydrique) synthétisent des composés secondaires (fiavonoides, coumarines, terpènes...) de protection et de défense. Les plantes d'altitude par exemple qui sont exposées à des conditions climatiques et environnementales difficiles, ont tendance à synthétiser des substances antioxydantes et antiradicalaires. Une investigation phytochirnique de ces plantes a conduit à la découverte de nouvelles molécules actives. Ainsi plusieurs plantes alpines ont été sélectionnées en fonction de leur habitat en vue de les soumettre aux tests biologiques (antifongiques) et chimiques (antiradicalaires) menés en routine dans notre laboratoire. Dans ce criblage biologique préliminaire, les extraits d'Eriophorum scheuchzeri Hoppe (Cyperaceae) ont réagi positivement aux différents tests. Il a donc été décidé d'entreprendre l'isolement des composés actifs. La première partie de ce travail a consisté à détecter, isoler et caractériser les composés naturels actifs présents dans l'extrait apolaire d' Eriophorum scheuchzeri. Parmi les huit composés isolés, quatre d'entre eux sont nouveaux. Un de ces produits est une flavanone et trois sont de nouvelles isoflavones, particulièrement intéressantes car elles possèdent des groupements C-méthylés au niveau du cycle B. Les flavonoides C-méthylés sont peu répandus dans le règne végétal et les rares exemples connus sont généralement C-méthylés sur le cycle A. Les quatre autres composés isolés n'ont jamais été décrits dans cette famille. Il s'agit d' isoflavones, les parvisoflavones A et B et la cajanine. Enfin, la flavone tricine, flavonoide caractéristique des Cyperaceae et des Poaceae a également été isolée. La deuxième partie de ce travail a consisté à caractériser les constituants polaires présents dans l'extrait methanolique. L'extrait a été analysé par chromatographie analytique couplée à différentes méthodes spectroscopiques (LC-UV-MS et LC-UV-1H RMN). De cette façon, douze flavonoides et un dérivé du phénylpropane, l'acide chlorogénique ont été identifiés. Les flavonoides tri-glycosylés ont dû être isolés afin de déterminer la nature et l'enchaînement des sucres. Finalement, l'espèce Eriophorum scheuchzeri a été comparée à deux autres espèces d' Eriophorum, soit E. angustifolium et E. latifolium. En conclusion, cette étude phytochimique a abouti à l'isolement de plusieurs nouvelles isoflavones aux activités antioxydantes et antifongiques ainsi qu'oestrogéniques.

Out-of-sample forecast tests robust to the choice of window size

This paper proposes new methodologies for evaluating out-of-sample forecastingperformance that are robust to the choice of the estimation window size. The methodologies involve evaluating the predictive ability of forecasting models over a wide rangeof window sizes. We show that the tests proposed in the literature may lack the powerto detect predictive ability and might be subject to data snooping across differentwindow sizes if used repeatedly. An empirical application shows the usefulness of themethodologies for evaluating exchange rate models' forecasting ability.

Impact of Duration of Primary Education on School Enrollment, Graduation and Drop-outs: A Cross- Country Analysis

Using a panel data for non-OECD countries covering the period 1970-2012, this chapter analyzes the impact of the duration of primary education on school enrollment, drop-out and completion rates. The empirical results show that for children in elementary school one ad- ditional grade of primary education have a negative impact on the enrollment rate, while the e ect on drop-outs is positive. Analogously, it is obtained that an additional grade in primary education reduces the enrollment rate in secondary education. These results are in line with the fertility model approach, that is, in developing and underdeveloped countries parents do not have incentive to send children to school given the high perceived economic value of children.
