The impact of theoretical chemistry in Biology

Els avenços en les bases dels mètodes teòrics i l'espectacular desenvolupament de la potència de càlcul han fet possible progressar enormement en el somni dels fundadors de la química, és a dir, ser capaços d'estudiar amb mètodes computacionals el conjunt de processos químics. Actualment, la química teòrica està completant el darrer avenç: intentar esdevenir l'eina més recent per a comprendre la naturalesa química dels éssers vius. Aquesta revisió pretén mostrar com els mètodes de la química teòrica, originalment desenvolupats per a examinar molècules petites en fase gas, han evolucionat per a assolir la complexa descripció de sistemes biològics.

The pivot player in handball and patterns detection - instrument

The theoretical context of this study is related with the observational methodology in the context of group games and sports studies, specifically Handball. Thus, this study intends to analyze the performance of the pivot player in the World Cup 2007 - Germany, European 2008 - Norway 2008 and China OG 2008 in a qualitative dimension. Our purpose was to get as much information as possible about the whole activity of the pivot player, by identifying sequential patterns of behaviour or conduct of the player/game, by using the sequential analysis. The observation instrument used to meet the main purpose of this work consists of a combination of format fields (FF) and systems of categories (SC). The codifications undertaken occurred in several handball games. Using this instrument we have shown that it provides support for the purposes for which it was developed, allowing more research into the offensive process of handball. Besides this, it makes possible the analysis of aspects of the game through perspective and contextual sequences, which we consider to be more accurate, to fit the "reality" of a game such as handball.

Social reciprocity measures based on dyadic discrepancies: Methodological review and software development

This paper examines statistical analysis of social reciprocity at group, dyadic, and individual levels. Given that testing statistical hypotheses regarding social reciprocity can be also of interest, a statistical procedure based on Monte Carlo sampling has been developed and implemented in R in order to allow social researchers to describe groups and make statistical decisions.

School burnout in adolescents : Differences in background variables and exploration of school-related stress at the end of compulsory schooling

The aim of this study is to contribute to a better understanding of the risk factors associated with school burnout, which has recently been described as a syndrome of emotional exhaustion due to school demands, cynical and detached attitude towards school and feelings of inadequacy as a student (Salmela-Aro, Kiuru, Pietikainen & Jokela, 2008a). The research focuses on students in the last years of compulsory schooling, period in which burnout has not received much attention yet. A total of 342 adolescents (Mean age = 14.84) were asked to complete questionnaires about school burnout, school-related stress and background variables. The results showed differences in school burnout by gender, grade level and school track, with girls, last grade of compulsory school and high-track classes, showing the highest scores. No difference was observed with respect to grade retention. Several types of school stress were identified, with stress type Success related to pressures to succeed and concerns about the academic future being the highest. Finally, stress and burnout were strongly and positively correlated, and the type of stress Success was the best predictor of overall Burnout, Exhaustion and Inadequacy dimension scores. The results are discussed in relation to their theoretical relevance and implications for the prevention of school burnout in adolescents.

La pertinence en science forensique. Une (en)quête épistémologique et empirique

A criminal investigation requires to search and to interpret vestiges of a criminal act that happened in a past time. The forensic investigator arises in this context as a critical reader of the investigation scene, in search of physical traces that should enable her to tell a story of the offence/crime which allegedly occurred. The challenge of any investigator is to detect and recognise relevant physical traces in order to provide forensic clues for investigation and intelligence purposes. Inspired by this obser- vation, the current research focuses on the following questions : What is a relevant physical trace? And, how does the forensic investigator know she is facing one ? The interest of such questions is to provide a definition of a dimension often used in forensic science but never studied in its implications and operations. This doctoral research investigates scientific paths that are not often explored in forensic science, by using semiotic and sociological tools combined with statistical data analysis. The results are shown following a semiotic path, strongly influenced by Peir- ce's studies, and a second track, called empirical, where investigations data were analysed and forensic investigators interviewed about their work practices in the field. By the semiotic track, a macroscopic view is given of a signification process running from the discove- red physical trace at the scene to what is evaluated as being relevant for the investigator. The physical trace is perceived in the form of several signs, whose meaning is culturally codified. The reasoning should consist of three main steps : 1- What kind of source does the discovered physical trace refer to ? 2- What cause/activity is at the origin of this source in the specific context of the case ? 3- What story can be told from these observations ? The stage 3 requires to reason in creating hypotheses that should explain the presence of the discovered trace coming from an activity ; the specific activity that is related to the investigated case. To validate this assumption, it would depend on their ability to respond to a rule of relevancy. The last step is the symbolisation of the relevancy. The rule would consist of two points : the recognition of the factual/circumstantial relevancy (Is the link between the trace and the case recognised with the formulated hypothesis ? ) and appropriate relevancy (What investment is required to collect and analyse the discovered trace considering the expected outcome at the investigation/intelligence level?). This process of meaning is based on observations and a conjectural reasoning subject to many influences. In this study, relevancy in forensic science is presented as a conventional dimension that is symbolised and conditioned by the context, the forensic investigator's practice and her workplace environment (culture of the place). In short, the current research states relevancy results of the interactions between parameters from situational, structural (or organisational) and individual orders. The detection, collection and analysis of relevant physical traces at scenes depends on the knowledge and culture mastered by the forensic investigator. In the study of the relation relevant trace-forensic investigator, this research introduces the KEE model as a conceptual map that illustrates three major areas of forensic knowledge and culture acquisition, involved in the research and evaluation of the relevant physical trace. Through the analysis of the investigation data and interviews, the relationship between those three parameters and the relevancy was highlighted. K, for knowing, embodies a rela- tionship to the immediate knowledge allowing to give an overview of the reality at a specific moment ; an important point since relevancy is signified in a context. E, for education, is considered through its relationship with relevancy via a culture that tends to become institutionalised ; it represents the theoretical knowledge. As for the parameter E, for experience, it exists in its relation to relevancy in the adjustments of the strategies of intervention (i.e a practical knowledge) of each practitioner having modulated her work in the light of success and setbacks case after case. The two E parameters constitute the library resources for the semiotic recognition process and the K parameter ensures the contextualisation required to set up the reasoning and to formulate explanatory hypotheses for the discovered physical traces, questioned in their relevancy. This research demonstrates that the relevancy is not absolute. It is temporal and contextual; it is a conventional and relative dimension that must be discussed. This is where the whole issue of the meaning of what is relevant to each stakeholder of the investigation process rests. By proposing a step by step approach to the meaning process from the physical trace to the forensic clue, this study aims to provide a more advanced understanding of the reasoning and its operation, in order to streng- then forensic investigators' training. This doctoral research presents a set of tools critical to both pedagogical and practical aspects for crime scene management while identifying key-influences with individual, structural and situational dimensions. - Une enquête criminelle consiste à rechercher et à faire parler les vestiges d'un acte incriminé passé. L'investigateur forensique se pose dans ce cadre comme un lecteur critique des lieux à la recherche de traces devant lui permettre de former son récit, soit l'histoire du délit/crime censé s'être produit. Le challenge de tout investigateur est de pouvoir détecter et reconnaître les traces dites pertinentes pour fournir des indices forensiques à buts d'enquête et de renseignement. Inspirée par un tel constat, la présente recherche pose au coeur de ses réflexions les questions suivantes : Qu'est-ce qu'une trace pertinente ? Et, comment fait le forensicien pour déterminer qu'il y fait face ? L'intérêt de tels questionnements se comprend dans la volonté de définir une dimension souvent utili- sée en science forensique, mais encore jamais étudiée dans ses implications et fonctionnements. Cette recherche se lance dans des voies d'étude encore peu explorées en usant d'outils sémiotiques et des pratiques d'enquêtes sociologiques combinés à des traitements statistiques de données. Les résultats sont représentés en suivant une piste sémiotique fortement influencée par les écrits de Peirce et une seconde piste dite empirique où des données d'interventions ont été analysées et des investigateurs forensiques interviewés sur leurs pratiques de travail sur le terrain. Par la piste sémiotique, une vision macroscopique du processus de signification de la trace en élément pertinent est représentée. La trace est perçue sous la forme de plusieurs signes dont la signification est codifiée culturellement. Le raisonnement se formaliserait en trois principales étapes : 1- Quel type de source évoque la trace détectée? 2- Quelle cause/activité est à l'origine de cette source dans le contexte précis du cas ? 3- Quelle histoire peut être racontée à partir de ces observations ? Cette dernière étape consiste à raisonner en créant des hypothèses devant expliquer la présence de la trace détectée suite à une activité posée comme étant en lien avec le cas investigué. Pour valider ces hypothèses, cela dépendrait de leur capacité à répondre à une règle, celle de la pertinence. Cette dernière étape consiste en la symbolisation de la pertinence. La règle se composerait de deux points : la reconnaissance de la pertinence factuelle (le lien entre la trace et le cas est-il reconnu dans l'hypothèse fournie?) et la pertinence appropriée (quel est l'investissement à fournir dans la collecte et l'exploitation de la trace pour le bénéfice attendu au niveau de l'investigation/renseignement?). Tout ce processus de signification se base sur des observations et un raisonnement conjectural soumis à de nombreuses influences. Dans cette étude, la pertinence en science forensique se formalise sous les traits d'une dimension conventionnelle, symbolisée, conditionnée par le contexte, la pratique de l'investigateur forensique et la culture du milieu ; en somme cette recherche avance que la pertinence est le fruit d'une interaction entre des paramètres d'ordre situationnel, structurel (ou organisationnel) et individuel. Garantir la détection, la collecte et l'exploitation des traces pertinentes sur les lieux dépend de la connaissance et d'une culture maîtrisées par le forensicien. Dans l'étude du rapport trace pertinente-investigateur forensique, la présente recherche pose le modèle SFE comme une carte conceptuelle illustrant trois grands axes d'acquisition de la connaissance et de la culture forensiques intervenant dans la recherche et l'évaluation de la trace pertinente. Par l'analyse des données d'in- terventions et des entretiens, le rapport entre ces trois paramètres et la pertinence a été mis en évidence. S, pour savoir, incarne un rapport à la connaissance immédiate pour se faire une représentation d'une réalité à un instant donné, un point important pour une pertinence qui se comprend dans un contexte. F, pour formation, se conçoit dans son rapport à la pertinence via cette culture qui tend à s'institutionnaliser (soit une connaissance théorique). Quant au paramètre E, pour expérience, il se comprend dans son rapport à la pertinence dans cet ajustement des stratégies d'intervention (soit une connaissance pratique) de chaque praticien ayant modulé leur travail au regard des succès et échecs enregistrés cas après cas. F et E formeraient la bibliothèque de ressources permettant le processus de reconnaissance sémiotique et S assurerait la contextualisation nécessaire pour poser le raisonnement et formuler les hypothèses explicatives pour les traces détectées et questionnées dans leur pertinence. Ce travail démontre que la pertinence n'est pas absolue. Elle est temporelle et contextuelle, c'est une dimension conventionnelle relative et interprétée qui se doit d'être discutée. C'est là que repose toute la problématique de la signification de ce qui est pertinent pour chaque participant du processus d'investigation. En proposant une lecture par étapes du processus de signification depuis la trace à l'indice, l'étude vise à offrir une compréhension plus poussée du raisonnement et de son fonctionnement pour renforcer la formation des intervenants forensiques. Cette recherche présente ainsi un ensemble d'outils critiques à portée tant pédagogiques que pratiques pour la gestion des lieux tout en identifiant des influences-clé jouées par des dimensions individuelles, structurelles et situationnelles.

The role of magma rheology during emplacement of the Listino Suite, Adamello Massif, Italy

This thesis studies individual and contextual antecedents of anti-immigrant attitudes by drawing on intergroup threat and contact, social representation, and value theories. As an alternative to previous multilevel research on the topic, it aims to articulate levels of analysis by putting forward a Person x Context Interaction approach. Moreover, rather than focussing exclusively on the impact of a large immigrant proportion, by introducing ideological climates, it develops and examines the normative societal context in which individuals are embedded. The studies largely draw on cross-sectional survey data across Swiss municipalities (Studies 1 to 3) and European countries (Study 4), but are complemented by elite discourses (Study 5) and online collected survey data (Study 6). Study 1 distinguishes between valued and devalued immigrants, thereby shedding light on the impact of immigrant proportion on intergroup contact and threat. Study 2 focuses on the link between immigrant proportion and attitudes towards the Muslim veil by examining its joint impact with conservative ideologies on the individual and municipality level. Aiming to explain threat related to immigrants, the interplay between immigrant proportion and ideological climates is studied across Swiss municipalities (Study 3) and European countries (Study 4). In addition, by adopting a Person x Context Interaction approach, it is investigated whether a context galvanizes individuals already prone to viewing immigrants as threatening, or mobilizes those generally least likely to express prejudice. Finally, to better understand the role political elites play in fuelling ideological climates, the official discourses on the 2011 England riots are analysed (Study 5). With online survey data collected during the riots, it is then shown that once endorsed, threat-eliciting climates are likely to mobilize negative ethnic diversity attitudes in the larger population (Study 6). Overall, this thesis proposes an integrative approach to studying anti-immigrant attitudes and discusses theoretical and methodological implications. - La présente thèse se penche sur les antécédents individuels et contextuels des attitudes négatives envers les immigré e s, en combinant les théories de la menace intergroupe, du contact, des représentations sociales et des valeurs. Elle a plus précisément pour but d'articuler différents niveaux d'analyse à travers une approche insistant sur les interactions entre Individu et Contexte. Ce faisant, elle propose une alternative aux recherches précédentes sur le thème, basées sur une perspective multiniveau plus « classique ». Au lieu de se pencher uniquement sur l'impact de la présence de populations immigrées dans un lieu donné, la recherche réalisée a par ailleurs développé et étudié le concept de climat idéologique, à savoir le contexte normatif au sein duquel les individus sont plongés au quotidien. Les études composant cette thèse se basent essentiellement sur des données d'enquête de grande échelle, récoltées dans diverses municipalités Suisses (Etudes 1 à 3) ou divers pays Européens (Etude 4). Elles sont complétées par l'analyse de discours politiques (Etude 5) et de données récoltées sur internet (Etude 6). Distinguant entre immigré-e'S valorisé-e s et dévalorisé-e-s, l'Etude 1 a eu pour but de mettre en lumière l'impact de la présence d'immigré e s sur le contact et la menace intergroupes. L'Etude 2 a, quant à elle, examiné si la présence d'immigré e s interagit avec les idéologies conservatrices, tant au niveau individuel que municipal, pour expliquer les attitudes envers le voile. Dans le même ordre idée, les études suivantes ont mis en exergue les effets conjoints de la présence d'immigré-e s et du climat idéologique au niveau des municipalités suisses (Etude 3) ou des pays Européens (Etude 4). En s'intéressant aux interactions entre Individu et Contexte, ces études ont en particulier cherché à observer dans quelle mesure ce dernier pouvait galvaniser les attitudes de personnes qui avaient déjà tendance à percevoir les immigré e s comme une menace ou, au contraire, mobiliser des individus desquels on n'attendrait pas de telles attitudes. Pour finir, les dernières études ont eu pour but de mettre en lumière la manière dont les élites politiques alimentent les climats idéologiques. Dans ce but, l'Etude 5 a analysé les discours officiels donnés pendant les émeutes qui ont secoué Londres en 2011, alors que l'Etude 6 a démontré comment le fait d'être en accord avec le message de menace véhiculé par ces discours avait poussé des individus égalitaires à exprimer des attitudes négatives envers la diversité ethnique. Dans l'ensemble, la présente thèse propose donc une approche intégrative d'étudier les attitudes négatives envers les immigré-e-s, et en discute les implications théoriques et méthodologiques.

INdividual SUrveys in RAllies (INSURA), A new tool for exploring transnational activism?

Prior the middle of the 90', interviewing participants in protest events was quiet rare. INdividual SUrveys in RAllies (INSURA) did enter the social researcher's usual toolkit only in the following decade after Favre, Fillieule and Mayer (1997) conducted such a survey with as a primary ambition to build a solid methodological framework that could be subsequently applied by other researchers. After some years of intensive use of INSURA, one is entitled to wonder whether that technique has fulfilled social researchers' hopes or not. In that paper, results of a collective work on alter-global rallies in Evian and Saint- Denis are used to answer three interrelated questions. Firstly, some basic methodological questions about how to collect data on crowds are adressed. What are the specific constraints of interviewing people at the very moment they are "expressing" a political opinion? What specific constraints result from the morphology of the covered events, that is to say, how to build a valid sampling frame? The authors then turn to a more general point about the questions that can be solved, or not, using that technique. Secondly it is the strenghts and weaknesses of INSURA in exploring the transnational dimension of alter global protests that is adressed. The authors show that INSURA is certainly well suited to explore the demographics of alter-global events, as well as relational networks of individuals and multiple belongings. On the contrary, it is assumed that organization networks and movement's boundaries are far more difficult to explore through that method, a fact that seriously limits international cross comparisons of events and movements based on that tool.

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.

A critical analysis of three psychological research programs of doping behaviour

Objectives To consider the various specific substances-taking activities in sport an examination of three psychological models of doping behaviour utilised by researchers is presented in order to evaluate their real and potential impact, and to improve the relevance and efficiency of anti-doping campaigns. Design Adopting the notion of a "research program" (Lakatos, 1978) from the philosophy of science, a range of studies into the psychology of doping behaviour are classified and critically analysed. Method Theoretical and practical parameters of three research programs are critically evaluated (i) cognitive; (ii) drive; and (iii) situated-dynamic. Results The analysis reveals the diversity of theoretical commitments of the research programs and their practical consequences. The «cognitive program» assumes that athletes are accountable for their acts that reflect the endeavour to attain sporting and non-sporting goals. Attitudes, knowledge and rational decisions are understood to be the basis of doping behaviour. The «drive program» characterises the variety of traces and consequences on psychological and somatic states coming from athlete's experience with sport. Doping behaviour here is conceived of as a solution to reduce unconscious psychological and somatic distress. The «situated-dynamic program» considers a broader context of athletes' doping activity and its evolution during a sport career. Doping is considered as emergent and self-organized behaviour, grounded on temporally critical couplings between athletes' actions and situations and the specific dynamics of their development during the sporting life course. Conclusions These hypothetical, theoretical and methodological considerations offer a more nuanced understanding of doping behaviours, making an effective contribution to anti-doping education and research by enabling researchers and policy personnel to become more critically reflective about their explicit and implicit assumptions regarding models of explanations for doping behaviour.
