Social huddling and physiological thermoregulation are related to melanism in the nocturnal barn owl.

Endothermic animals vary in their physiological ability to maintain a constant body temperature. Since melanin-based coloration is related to thermoregulation and energy homeostasis, we predict that dark and pale melanic individuals adopt different behaviours to regulate their body temperature. Young animals are particularly sensitive to a decrease in ambient temperature because their physiological system is not yet mature and growth may be traded-off against thermoregulation. To reduce energy loss, offspring huddle during periods of cold weather. We investigated in nestling barn owls (Tyto alba) whether body temperature, oxygen consumption and huddling were associated with melanin-based coloration. Isolated owlets displaying more black feather spots had a lower body temperature and consumed more oxygen than those with fewer black spots. This suggests that highly melanic individuals display a different thermoregulation strategy. This interpretation is also supported by the finding that, at relatively low ambient temperature, owlets displaying more black spots huddled more rapidly and more often than those displaying fewer spots. Assuming that spot number is associated with the ability to thermoregulate not only in Swiss barn owls but also in other Tytonidae, our results could explain geographic variation in the degree of melanism. Indeed, in the northern hemisphere, barn owls and allies are less spotted polewards than close to the equator, and in the northern American continent, barn owls are also less spotted in colder regions. If melanic spots themselves helped thermoregulation, we would have expected the opposite results. We therefore suggest that some melanogenic genes pleiotropically regulate thermoregulatory processes.

Olympic social responsibility : a challenge for the future

Social responsibility, especially in the fields of education, society and peace, is one of the cornerstones of the olympic ideal and strategic vision (contribute to building a better world through sport). The article reviews the literature on organizational social responsibility (OSR) and the relationship between sport/olympism and OSR in order to examine the conditions governing the implementation and success of the International Olympic Committee's strategic vision. Several ways in which the IOC could promote a more ambitious and better-integrated social strategy: revise its performance model, notably evaluate and present in a social responsibility report; promote the adoption of OSR initiatives and strategies within the Olympic System from the bottom-up, rather than from the top-down; share best practices in the different countries for promoting and developing "sport for all"; create a World Agency for Development through Sport, or partnering and funding the international platform on sport and development; creating a World Agency for the International Governance of Sport. Two possible scenarios for the future of Olympic responsibility are finally discussed: strategy of "small steps" and a more ambitious local and global social strategy through sport and olympism.

El Aprendizaje de las habilidades sociales en la universidad. Análisis de una experiencia formativa en los grados de educación Social y trabajo Social

Se presenta una metodología formativa desarrollada en la asignatura de habilidades sociales de los grados otorgados por la Facultad de Educación Social y Trabajo Social Pere Tarrés de la Universidad Ramón Llull (Barcelona-España). A partir del análisis inicial de las competencias sociales de los estudiantes, se establece un plan de trabajo con la finalidad de que mejoren las habilidades sociales necesarias en el contexto profesional. La metodología se plantea como práctica supervisada que requiere la incorporación del estudiante en la organización, desarrollo y evaluación de la asignatura. Para facilitar esa incorporación se ha introducido un recurso narrativo que da sentido a todas las actividades. Se ha utilizado como indicadores de la validez social de esta metodología los datos recogidos a través encuestas de satisfacción de los estudiantes. Los resultados positivos de la experiencia justifican su difusión y su uso en otras universidades.

El desarrollo personal y profesional mediante el aprendizaje reflexivo : una experiencia en el grado de Educación Social

In the last years, an increase of the interest to develop educational practices in higher education, based on the approach of the reflective learning, is observed. Nevertheless, we scarcely find in our context researches or experiences that allow knowing students’ perceptions about this teaching and learning approach. We have developed an experience in the bachelor of Social Education at the University of Girona with the aim to contribute to the personal and professional development of future social educators in their initial training, using reflective learning methodology. In this article we present an evaluation of the experience based on students’ perceptions. They assessed the usefulness they think the module has for their training, the methodology and the activities. This evaluation has been carried out through in-depth interviews to 17 students who participated in the module in 2010-11 academic year. The results show that students assess positively the experience, either its general usefulness or the methodology of reflective learning, although they acknowledge some difficulties to carry out such a process which involves a high degree of introspection and a difficulty to set the boundaries in the narration of personal questions. The study also shows some challenges related on the need, but also the difficulty, to include personal and professional development as a powerful axis in the higher education curriculum, as well as elements linked to reflective learning assessment

Mentoring in the acquisition of professional skills through practices in companies by degree students

Abstract This work has had as objective to analyze the skills acquired through internships in business companies by students of the Faculty of Economics and Business at the University Pompeu Fabra. The internship is a basic item in order to obtain a hard connection between the University and social-economic world where University and Enterprises develop their activity. In this study we want to know about two aspects. The first one, we want to know the profit that is obtained from the Student as a consequence of internship and mentoring. Also, we want to study about the importance of mentoring as a principal element that establishes the relationship between the Student and the Company. Moreover, it has sought to analyze if certain factors such as the size of the company where the practices has been performed, the study rank level that was achieved or the fact of being a man or a woman, were among the determining factors at the time of acquiring the skills. The results presented here indicate that the size of the company that have been making the practices and the gender of the student are related to the acquisition of certain skills. There was not a statistically significant relationship related to the rank level have by the students in the practice. In the future we are going to study if the labor market Integration is easier if the Student has performed work placement. Keywords Skills; employability; internship; meatoring.

Analyse de réseau piéton et gestion scolaire: sinuosité, centricité et transport optimal régularisé

Que ce soit d'un point de vue, urbanistique, social, ou encore de la gouvernance, l'évolution des villes est un défi majeur de nos sociétés contemporaines. En offrant la possibilité d'analyser des configurations spatiales et sociales existantes ou en tentant de simuler celles à venir, les systèmes d'information géographique sont devenus incontournables dans la gestion et dans la planification urbaine. En cinq ans la population de la ville de Lausanne est passée de 134'700 à 140'570 habitants, alors que les effectifs de l'école publique ont crû de 12'200 à 13'500 élèves. Cet accroissement démographique associé à un vaste processus d'harmonisation de la scolarité obligatoire en Suisse ont amené le Service des écoles à mettre en place et à développer en collaboration avec l'université de Lausanne des solutions SIG à même de répondre à différentes problématiques spatiales. Établies en 1989, les limites des établissements scolaires (bassins de recrutement) ont dû être redéfinies afin de les réadapter aux réalités d'un paysage urbain et politique en pleine mutation. Dans un contexte de mobilité et de durabilité, un système d'attribution de subventions pour les transports publics basé sur la distance domicile-école et sur l'âge des écoliers, a été conçu. La réalisation de ces projets a nécessité la construction de bases de données géographiques ainsi que l'élaboration de nouvelles méthodes d'analyses exposées dans ce travail. Cette thèse s'est ainsi faite selon une dialectique permanente entre recherches théoriques et nécessités pratiques. La première partie de ce travail porte sur l'analyse du réseau piéton de la ville. La morphologie du réseau est investiguée au travers d'approches multi-échelles du concept de centralité. La première conception, nommée sinuo-centralité ("straightness centrality"), stipule qu'être central c'est être relié aux autres en ligne droite. La deuxième, sans doute plus intuitive, est intitulée centricité ("closeness centrality") et exprime le fait qu'être central c'est être proche des autres (fig. 1, II). Les méthodes développées ont pour but d'évaluer la connectivité et la marchabilité du réseau, tout en suggérant de possibles améliorations (création de raccourcis piétons). Le troisième et dernier volet théorique expose et développe un algorithme de transport optimal régularisé. En minimisant la distance domicile-école et en respectant la taille des écoles, l'algorithme permet de réaliser des scénarios d'enclassement. L'implémentation des multiplicateurs de Lagrange offre une visualisation du "coût spatial" des infrastructures scolaires et des lieux de résidence des écoliers. La deuxième partie de cette thèse retrace les aspects principaux de trois projets réalisés dans le cadre de la gestion scolaire. À savoir : la conception d'un système d'attribution de subventions pour les transports publics, la redéfinition de la carte scolaire, ou encore la simulation des flux d'élèves se rendant à l'école à pied. *** May it be from an urbanistic, a social or from a governance point of view, the evolution of cities is a major challenge in our contemporary societies. By giving the opportunity to analyse spatial and social configurations or attempting to simulate future ones, geographic information systems cannot be overlooked in urban planning and management. In five years, the population of the city of Lausanne has grown from 134'700 to 140'570 inhabitants while the numbers in public schools have increased from 12'200 to 13'500 students. Associated to a considerable harmonisation process of compulsory schooling in Switzerland, this demographic rise has driven schooling services, in collaboration with the University of Lausanne, to set up and develop GIS capable of tackling various spatial issues. Established in 1989, the school districts had to be altered so that they might fit the reality of a continuously changing urban and political landscape. In a context of mobility and durability, an attribution system for public transport subventions based on the distance between residence and school and on the age of the students was designed. The implementation of these projects required the built of geographical databases as well as the elaboration of new analysis methods exposed in this thesis. The first part of this work focuses on the analysis of the city's pedestrian network. Its morphology is investigated through multi-scale approaches of the concept of centrality. The first conception, named the straightness centrality, stipulates that being central is being connected to the others in a straight line. The second, undoubtedly more intuitive, is called closeness centrality and expresses the fact that being central is being close to the others. The goal of the methods developed is to evaluate the connectivity and walkability of the network along with suggesting possible improvements (creation of pedestrian shortcuts).The third and final theoretical section exposes and develops an algorithm of regularised optimal transport. By minimising home to school distances and by respecting school capacity, the algorithm enables the production of student allocation scheme. The implementation of the Lagrange multipliers offers a visualisation of the spatial cost associated to the schooling infrastructures and to the student home locations. The second part of this thesis recounts the principal aspects of three projects fulfilled in the context of school management. It focuses namely on the built of an attribution system for public transport subventions, a school redistricting process and on simulating student pedestrian flows.

Evasão do curso de química da Universidade de Brasília: a interpretação do aluno evadido

This study aimed the investigation of the reasons that led undergraduate students of the Chemistry course at Universidade de Brasília to abandon the course before its conclusion. From the former students' point of view, the reasons that led them to leave the course were related to aspects of their academic life prior to university entrance, expectations which failed to be met by the course, the intricate nature of the academic system, personal and social experiences. Abandonment is a consequence of the problems he encounters during the course and takes on a connotation of protest, more than of failure.

La pressió social i el català a Europa

El treball parteix d'una afirmació: la pressió social (exercida de vegades per una persona influent, de vegades per milers) pot facilitar canvis en el règim lingüístic de la Unió Europea (o, més ben dit, en el de les institucions de la Unió) o, si més no, en elements de la seva política lingüística. Al llarg d'aquest treball hom justificarà aquesta afirmació amb una sèrie d'exemples, en què la pressió popular ha volgut deixar clar, davant d'Europa, la importància que donem a la llengua catalana.

Expertise and decision making among clinicians in investigations of alleged child sexual abuse

The purpose of the present thesis was to explore different aspects of decision making and expertise in investigations of child sexual abuse (CSA) and subsequently shed some light on the reasons for shortcomings in the investigation processes. Clinicians’ subjective attitudes as well as scientifically based knowledge concerning CSA, CSA investigation and interviewing were explored. Furthermore the clinicians’ own view on their expertise and what enhances this expertise was investigated. Also, the effects of scientific knowledge, experience and attitudes on the decision making in a case of CSA were explored. Finally, the effects of different kinds of feedback as well as experience on the ability to evaluate CSA in the light of children’s behavior and base rates were investigated. Both explorative and experimental methods were used. The purpose of Study I was to investigate whether clinicians investigating child sexual abuse (CSA) rely more on scientific knowledge or on clinical experience when evaluating their own expertise. Another goal was to check what kind of beliefs the clinicians held. The connections between these different factors were investigated. A questionnaire covering items concerning demographic data, experience, knowledge about CSA, selfevaluated expertise and beliefs about CSA was given to social workers, child psychiatrists and psychologists working with children. The results showed that the clinicians relied more on their clinical experience than on scientific knowledge when evaluating their expertise as investigators of CSA. Furthermore, social workers possessed stronger attitudes in favor of children than the other groups, while child psychiatrists had more negative attitudes towards the criminal justice system. Male participants held less strong beliefs than female participants. The findings indicate that the education of CSA investigators should focus more on theoretical knowledge and decision making processes as well as the role of beliefs In Study II school and family counseling psychologists completed a Child Sexual Abuse Attitude and Belief Scale. Four CSA related attitude and belief subscales were identified: 1. The Disclosure subscale reflecting favoring a disclosure at any cost, 2. The Pro-Child subscale reflecting unconditional belief in children's reports, 3. The Intuition subscale reflecting favoring an intuitive approach to CSA investigations, and 4. The Anti Criminal Justice System subscale reflecting negative attitudes towards the legal system. Beliefs that were erroneous according to empirical research were analyzed separately. The results suggest that some psychologists hold extreme attitudes and many erroneous beliefs related to CSA. Some misconceptions are common. Female participants tended to hold stronger attitudes than male participants. The more training in interviewing children the participants have, the more erroneous beliefs and stronger attitudes they hold. Experience did not affect attitudes and beliefs. In Study III mental health professionals’ sensitivity to suggestive interviewing in CSA cases was explored. Furthermore, the effects of attitudes and beliefs related to CSA and experience with CSA investigations on the sensitivity to suggestive influences in the interview were investigated. Also, the effect of base rate estimates of CSA on decisions was examined. A questionnaire covering items concerning demographic data, different aspects of clinical experience, self-evaluated expertise, beliefs and knowledge about CSA and a set of ambiguous material based on real trial documents concerning an alleged CSA case was given to child mental health professionals. The experiment was based on a 2 x 2 x 2 x 2 (leading questions: yes vs no) x (stereotype induction: yes vs no) x (emotional tone: pressure to respond vs no pressure to respond) x (threats and rewards: yes vs no) between-subjects factorial design, in which the suggestiveness of the methods with which the responses of the child were obtained were varied. There was an additional condition in which the material did not contain any interview transcripts. The results showed that clinicians are sensitive only to the presence of leading questions but not to the presence of other suggestive techniques. Furthermore, the clinicians were not sensitive to the possibility that suggestive techniques could have been used when no interview transcripts had been included in the trial material. Experience had an effect on the sensitivity of the clinicians only regarding leading questions. Strong beliefs related to CSA lessened the sensitivity to leading questions. Those showing strong beliefs on the belief scales used in this study were even more prone to prosecute than other participants when other suggestive influences than leading questions were present. Controversy exists regarding effects of experience and feedback on clinical decision making. In Study IV the impact of the number of handled cases and of feedback on the decisions in cases of alleged CSA was investigated. One-hundred vignettes describing cases of suspected CSA were given to students with no experience with investigating CSA. The vignettes were based on statistical data about symptoms and prevalence of CSA. According to the theoretical likelihood of CSA the children described were categorized as abused or not abused. The participants were asked to decide whether abuse had occurred. They were divided into 4 groups: one received feedback on whether their decision was right or wrong, one received information about cognitive processes involved in decision making, one received both, and one did not receive feedback at all. The results showed that participants who received feedback on their performance made more correct positive decisions and participants who got information about decision making processes made more correct negative decisions. Feedback and information combined decreased the number of correct positive decisions but increased the number of correct negative decisions. The number of read cases had in itself a positive effect on correct positive decision.

O ensino por problemas e trabalho experimental dos estudantes: reflexões teórico-metodológicas

This work focuses its attention in teaching through problems, as a methodological strategy in the system of chemistry learning situations. The philosophical and epistemological basis of our perspective are the works that were developed by M. Majmutov and M.M. Llantada, in the field of sciences didactics and in the social-historical context of the school, where the fundamental categories that structure teaching through problems are discussed: the problem, the problematic tasks and problematic, as main orientations in the process of construction of the knowledge by the students.

PhD Students’ Research Group Networks: a Qualitative Approach

This article examines the networks within the research groups where Spanish PhD students are pursuing their doctorate. Capó et al. (2007) used quantitative data to predict PhD students’ publishing performance from their background, attitudes, supervisors’ performance and research group networks. Variables related to the research group network had a negligible explanatory power on student performance once the remaining variables had been accounted for. In this article, a qualitative follow up of the same students is carried out using extreme case sampling and indepth interviews. The qualitative research shows networking as important for students. Out of the 115 aspects that students mention in the interviews as relevant to publishing in the qualitative research, 92 have to do with their supervisors, their research group or their network as a whole. Similarly, out of the 50 hindrances mentioned, 20 have to do with the networks or relations. The most commonly mentioned network-related topics are research group members pushing PhD students to publish, meeting researchers outside the research group, existence of other PhD students in the group, help with the PhD from group members, supervisor’s interest in the thesis, the possibility of discussing with experts on the PhD’s topic and frequent contact with the supervisor and research group members. Some of these characteristics were not, however, measured in the conventional quantitative social network survey

Percepció i coneixements dels estudiants d'infermeria sobre la violència en la parella

Les últimes dades de l'estudi europeu del 2014, sobre la violència de parella indiquen que gairebé 62 milions de dones europees, havien sofert actes de violència de gènere, entre els quals es destaca els relacionats amb la violència de parella (VP). Els maltractaments constitueixen un problema molt greu que genera al nostre país cada vegada més alarma social i més actuacions legals i professionals per fer-li front. El sistema de salut és, amb freqüència, el primer lloc al que les víctimes de violència domèstica acudeixen a la recerca d'assessorament i ajuda, sent aquest el motiu pel qual els professionals de la salut tenen un paper central per a la seva assistència. Aquests formen part implicada en el sistema de detecció, atenció i actuació. Per això, els plans d'estudi de Grau d'Infermeria recullen en el BOE la formació en VP des de l’àmbit universitari. L’objectiu del nostre estudi consisteix en la identificació de la percepció i dels coneixements en relació a la violència de parella dels estudiants del Grau d’Infermeria de la Universitat de Girona durant el curs acadèmic 2012-2013. Per a dur-lo a terme es va realitzar un anàlisi quantitatiu dels resultats a través de l’administració d’una enquesta sobre sis aspectes de la VP, l’enquesta incloïa el perfil demogràfic (sexe, edat i anys d'estudi) dels estudiants i les declaracions relatives a les seves percepcions i coneixements sobre la VP: causes d'abús; la identificació de les dones objecte de VP i del seus autors; creences de les infermeres; funcions perceptibles; i la preparació educativa. Els estudiants del Grau d’Infermeria mostren tenir un bon coneixement sobre les causes del abús en VP, així com una formació adequada. També cal destacar que un 54,42% dels alumnes enquestats es veuen capacitats per afrontar un cas de VP com a infermer/a. S’observa una millora de la formació educativa en el transcurs acadèmic. En 1r curs un 40,09% té una bona formació, aquest valor augmenta fins a un 56,58% a tercer curs, baixant lleugerament fins un 44,27% a 4rt curs. Els resultats obtinguts són semblats a estudis de mostres similars en estudiants d'infermeria de Memphis (EUA) i de la University of Southern Queensland (Austràlia) quant a coneixements i percepció sobre la VP. Encara que els resultats mostren un coneixement i una percepció sobre la VP adequada, destaquem que això no succeeix en gairebé un 40% dels enquestats. La introducció de matèries específiques sobre igualtat i sobre violència contra la dona en els plans d’estudis, pot esdevenir una mesura preventiva per revisar i corregir possibles mites i creences en VP. Per tant, és necessari millorar la formació del currículum en estudiants d'infermeria per la importància d'aquest greu problema de salut pública, donant major èmfasis en la satisfacció de les necessitats emocionals i en la comprensió dels diferents enfocaments en VP, especialment en mesures de prevenció i educació
