An affective approach to moral motivation

Over the last few years, there has been a surge of work in a new field called "moral psychology", which uses experimental methods to test the psychological processes underlying human moral activity. In this paper, I shall follow this line of approach with the aim of working out a model of how people form value judgements and how they are motivated to act morally. I call this model an "affective picture": 'picture' because it remains strictly at the descriptive level and 'affective' because it has an important role for affects and emotions. This affective picture is grounded on a number of plausible and empirically supported hypotheses. The main idea is that we should distinguish between various kinds of value judgements by focusing on the sort of state of mind people find themselves in while uttering a judgement. "Reasoned judgements" are products of rational considerations and are based on preliminary acceptance of norms and values. On the contrary, "basic value judgements" are affective, primitive and non-reflective ways of assessing the world. As we shall see, this analysis has some consequences for the traditional internalism-externalism debate in philosophy; it highlights the fact that motivation is primarily linked to "basic value judgements" and that the judgements we openly defend might not have a particular effect on our actions, unless we are inclined to have an emotional attitude that conforms to them.

Juridical double taxation by cross border transactions: the Block Case (C-67/08)

Treaty Establishing the European Community, operative until December 1st 2009, had already established in its article 2 the mission of the up until then European Community and actual European Union is to promote an harmonious, equilibrated and sustainable development of the economic activities of the whole Community. This Mission must be achieved by establishing a Common Market, an Economic and Monetary Union and the realization of Common Policies. One of the instruments to obtain these objectives is the use of free circulation of people, services and capitals inside the Common and Interior Market of the European Union. The European Union is characterized by the confirmation of the total movement of capitals, services and individuals and legal peoples’ freedom; freedom that was already predicated by the Maastricht Treaty, through the suppression of whatever obstacles which are in the way of the objectives before exposed. The old TEC in its Title III, now Title IV of the Treaty on the Functioning of the European Union, covered the free circulation of people, services and capitals. Consequently, the inclusion of this mechanism inside one of the regulating texts of the European Union indicates the importance this freedom supposes for the European Union objectives’ development. Once stood up the relevance of the free movement of people, services and capitals, we must mention that in this paper we are going to centre our study in one of these freedoms of movement: the free movement of capital. In order to analyze in detail the free movement of capital within the European framework, we are going to depart from the analysis of the existent case law of the Court of Justice of the European Union. The use of jurisprudence is basic to know how Community legislation is interpreted. For this reason, we are going to develop this work through judgements dictated by the European Union Court. This way we can observe how Member States’ regulating laws and the European Common Law affect the free movement of capital. The starting point of this paper will be the Judgement C-67/08 European Court of Justice of February 12th 2009, known as Block case. So, following the argumentation the Luxemburg Court did about the mentioned case, we are going to develop how free movement of capital could be affected by the current disparity of Member States’ legislation. This disparity can produce double taxation cases due to the lack of tax harmonized legislation within the interior market and the lack of treaties to avoid double taxation within the European Union. Developing this idea we are going to see how double taxation, at least indirectly, can infringe free movement of capital.

New developments and applications in modelling occupational exposure to airborne contaminants

Résumé: L'évaluation de l'exposition aux nuisances professionnelles représente une étape importante dans l'analyse de poste de travail. Les mesures directes sont rarement utilisées sur les lieux même du travail et l'exposition est souvent estimée sur base de jugements d'experts. Il y a donc un besoin important de développer des outils simples et transparents, qui puissent aider les spécialistes en hygiène industrielle dans leur prise de décision quant aux niveaux d'exposition. L'objectif de cette recherche est de développer et d'améliorer les outils de modélisation destinés à prévoir l'exposition. Dans un premier temps, une enquête a été entreprise en Suisse parmi les hygiénistes du travail afin d'identifier les besoins (types des résultats, de modèles et de paramètres observables potentiels). Il a été constaté que les modèles d'exposition ne sont guère employés dans la pratique en Suisse, l'exposition étant principalement estimée sur la base de l'expérience de l'expert. De plus, l'émissions de polluants ainsi que leur dispersion autour de la source ont été considérés comme des paramètres fondamentaux. Pour tester la flexibilité et la précision des modèles d'exposition classiques, des expériences de modélisations ont été effectuées dans des situations concrètes. En particulier, des modèles prédictifs ont été utilisés pour évaluer l'exposition professionnelle au monoxyde de carbone et la comparer aux niveaux d'exposition répertoriés dans la littérature pour des situations similaires. De même, l'exposition aux sprays imperméabilisants a été appréciée dans le contexte d'une étude épidémiologique sur une cohorte suisse. Dans ce cas, certains expériences ont été entreprises pour caractériser le taux de d'émission des sprays imperméabilisants. Ensuite un modèle classique à deux-zone a été employé pour évaluer la dispersion d'aérosol dans le champ proche et lointain pendant l'activité de sprayage. D'autres expériences ont également été effectuées pour acquérir une meilleure compréhension des processus d'émission et de dispersion d'un traceur, en se concentrant sur la caractérisation de l'exposition du champ proche. Un design expérimental a été développé pour effectuer des mesures simultanées dans plusieurs points d'une cabine d'exposition, par des instruments à lecture directe. Il a été constaté que d'un point de vue statistique, la théorie basée sur les compartiments est sensée, bien que l'attribution à un compartiment donné ne pourrait pas se faire sur la base des simples considérations géométriques. Dans une étape suivante, des données expérimentales ont été collectées sur la base des observations faites dans environ 100 lieux de travail différents: des informations sur les déterminants observés ont été associées aux mesures d'exposition des informations sur les déterminants observés ont été associé. Ces différentes données ont été employées pour améliorer le modèle d'exposition à deux zones. Un outil a donc été développé pour inclure des déterminants spécifiques dans le choix du compartiment, renforçant ainsi la fiabilité des prévisions. Toutes ces investigations ont servi à améliorer notre compréhension des outils des modélisations ainsi que leurs limitations. L'intégration de déterminants mieux adaptés aux besoins des experts devrait les inciter à employer cet outil dans leur pratique. D'ailleurs, en augmentant la qualité des outils des modélisations, cette recherche permettra non seulement d'encourager leur utilisation systématique, mais elle pourra également améliorer l'évaluation de l'exposition basée sur les jugements d'experts et, par conséquent, la protection de la santé des travailleurs. Abstract Occupational exposure assessment is an important stage in the management of chemical exposures. Few direct measurements are carried out in workplaces, and exposures are often estimated based on expert judgements. There is therefore a major requirement for simple transparent tools to help occupational health specialists to define exposure levels. The aim of the present research is to develop and improve modelling tools in order to predict exposure levels. In a first step a survey was made among professionals to define their expectations about modelling tools (what types of results, models and potential observable parameters). It was found that models are rarely used in Switzerland and that exposures are mainly estimated from past experiences of the expert. Moreover chemical emissions and their dispersion near the source have also been considered as key parameters. Experimental and modelling studies were also performed in some specific cases in order to test the flexibility and drawbacks of existing tools. In particular, models were applied to assess professional exposure to CO for different situations and compared with the exposure levels found in the literature for similar situations. Further, exposure to waterproofing sprays was studied as part of an epidemiological study on a Swiss cohort. In this case, some laboratory investigation have been undertaken to characterize the waterproofing overspray emission rate. A classical two-zone model was used to assess the aerosol dispersion in the near and far field during spraying. Experiments were also carried out to better understand the processes of emission and dispersion for tracer compounds, focusing on the characterization of near field exposure. An experimental set-up has been developed to perform simultaneous measurements through direct reading instruments in several points. It was mainly found that from a statistical point of view, the compartmental theory makes sense but the attribution to a given compartment could ñó~be done by simple geometric consideration. In a further step the experimental data were completed by observations made in about 100 different workplaces, including exposure measurements and observation of predefined determinants. The various data obtained have been used to improve an existing twocompartment exposure model. A tool was developed to include specific determinants in the choice of the compartment, thus largely improving the reliability of the predictions. All these investigations helped improving our understanding of modelling tools and identify their limitations. The integration of more accessible determinants, which are in accordance with experts needs, may indeed enhance model application for field practice. Moreover, while increasing the quality of modelling tool, this research will not only encourage their systematic use, but might also improve the conditions in which the expert judgments take place, and therefore the workers `health protection.

Criteris d'avaluació de la credibilitat en les denúncies de violència de gènere

La Llei Integral de Mesures contra la Violència de Gènere estableix una sèrie de mesures legislatives que tenen per objecte el reconeixement dels drets de les víctimes de la violència, enfortir la sensibilitat ciutadana davant de la violència de gènere, instaurar un sistema de serveis socials d’atenció i de recuperació de les víctimes, garantir els seus drets econòmics i laborals, instaurar un sistema institucional de tutela, determinar un marc penal i processal i garantir la coordinació de tots aquells recursos que es dediquen a aquesta qüestió. Conscients de la importància d’aquesta Llei, de les dificultats que deriven de la seva aplicació, així com de la nostra experiència en la pràctica forense en casos de violència domèstica i de gènere, neix la idea de realitzar la recerca d’aquest estudi. Una recerca que pretén establir, a partir de l’anàlisi dels relats de dones víctimes de violència de gènere en la relació de parella, criteris de credibilitat que permetin validar les seves declaracions. Criteris obtinguts a partir de les mateixes paraules de les víctimes. Partint d’una metodologia mixta, quantitativa i qualitativa, hem obtingut uns resultats que ens han permès definir un sistema de criteris de credibilitat genuïns i discriminadors. Una discriminació obtinguda a partir de la comparació de les declaracions de dues mostres: víctimes reals i víctimes simulades. I, fruit d’aquesta comparació, la discontinuïtat narrativa, els detalls estranys, la reproducció de converses, les correccions espontànies, l’ambivalència i ambigüitat vers l’agressor, la violència indirecta, suscitant por i terror, la por a les represàlies, la imposició i intimitat del secret, la indefensió, l’evolució de la violència i progressió de la asimetria de poder, la dualitat de la conducta domèstica / imatge social de l’home, el control ampli masculí cognitiu-conductual, la descripció contextualitzada de microviolències, les estratègies de supervivència de la dona i el relat inhibit amb vergonya, han resultat criteris de credibilitat de les dones víctimes de violència de gènere que ens permetran validar el seu relat.

Criterios de evaluación de la credibilidad en las denuncias de violencia de género

Esta investigación contrasta los relatos de dos muestras de mujeres. La primera, víctimas reales de violencia de género en la relación de pareja; la segunda, deliberadamente ofrecen relatos falsos sobre esta misma problemática. Los resultados muestran una diferencia cualitativa significativa en base a los criterios de credibilidad definidos. Al mismo tiempo, el estudio ha encontrado otros criterios de credibilidad genuinos, que conforman el discurso explicativo que permite validar sus declaraciones.

Supervisió i control de la lectura: anàlisi de procediments, judicis metacognitius i resultats de comprensió en estudiants d'Educació Secundària Obligatòria

Els processos de comprensió lectora són complexes, i requereixen de l’ús autorregulat, conscient i deliberat de la metacognició en les seves dues vessants: supervisió i control. L’objectiu d’aquest projecte és analitzar les relacions entre aquests dos components, i la seva repercussió en la comprensió lectora que finalment s’assoleix. Per tal de tractar aquesta qüestió s’han analitzat els processos de lectura seguits per 60 alumnes d’Educació Secundària Obligatòria. La presència i el tipus de relectura ha estat considerada com a mesura de control (estratègia emprada per millorar la pròpia comprensió), mentre que els judicis metacognitius són considerats com a mesura de supervisió. També es va elaborar una prova de comprensió lectora incloent preguntes que requerissin diferents nivells de processament cognitiu, de més superficial a més profund. Els nostres resultats preliminars mostren una relació entre l’ajust dels judicis metacognitius i la comprensió lectora assolida; els lectors que millor entenen el text tendeixen a ser els que millor supervisen la seva comprensió. La relectura també s’ha mostrat útil per millorar la comprensió, ja que els participants obtenen millors resultats després de rellegir. Per últim, s’ha trobat una relació significativa entre l’ajust dels judicis metacognitius i la relectura. D’una banda, aquests resultats subratllen la importància de la supervisió i el control en la comprensió lectora, i ofereixen evidències per explicar les complexes relacions entre supervisió, control, i resultats de comprensió. A més, els processos de lectura i els objectius amb què hom rellegeix apareixen com a temes rellevants que requereixen ser investigats per comprendre millor la interacció entre els processos de supervisió i control en la comprensió lectora. D’altra banda, els resultats tenen valuoses implicacions educatives, ja que proporcionen evidències de la importància d’ensenyar processos metacognitius des d’un punt de vista estratègic, en contraposició a les “tècniques”, per tal de millorar la comprensió lectora.

Novel Strategies For Food Risk

Our every day decision-making behaviour relating to food choice is taken in the context of considerations of health, naturalness, economy, convenience and what we perceive as ‘risk’. Risk perception is now as important as any technical assessment of risk. In order to communicate effectively with the consumer about food risks, the importance of the exchange of information and opinions among the interested parties is recognised (FAO/WHO, 1998). Risk communication is “not just a matter of ensuring that one’s messages are delivered and listened to â€_.. also very much a process of empowering individuals â€_. to sharpen the skills necessary to make balanced judgements on risksâ€ù, (Scherer 1991). This safefood review, conducted on an all-island of Ireland basis, provides valuable insights into the perception of food safety risk from consumers on the island of Ireland and the food safety expert viewpoint. It explores the barriers to communicating with consumers on the island of Ireland about food safety risk. It also studies the barriers to promoting and practising good food hygiene - subgroups within the population are identified as being at ‘high risk’ because of inadequate levels of knowledge or more frequently resulting from not believing that the investment of time and effort in good food safety practice is worthwhile.

The role of ACC in Anosognosia: a TMS study.

Transcranial Magnetic Stimulation (TMS) is a technic wich allows Neuroscience researchers to disrupt or improve the normal brain activity in a strategic and focalized cortical areas. Our present work using TMS is focused on research the role of Anterior Cingolate Cortex (ACC) to discover its causal implications over autoreferencial judgments of own behaviour using healthy controls.If our hypothesis is confirmed and ACC has a keyrole in those autoreferential judgements; new research lines and stimulation techniques could strenghten to improve quality of life and feelings of overcoming to thousands of mental health patients and neurodegenerative.

Ageing prisoners' health care: analysing the legal settings in Europe and the United States.

BACKGROUND: Relatively little is known about the current health care situation and the legal rights of ageing prisoners worldwide. To date, only a few studies have investigated their rights to health care. However, elderly prisoners need special attention. OBJECTIVE: The aim of this article is to critically review the health care situation of older prisoners by analysing the relevant national and international legal frameworks with a particular focus on Switzerland, England and Wales, and the United States (U.S.). METHODS: Publications on legal frameworks were searched using Web of Science, PubMed, MEDLINE, HeinOnline, and the National Criminal Justice Reference Service. Searches utilizing combinations of keywords relating to ageing prisoners were performed. Relevant reports and policy documents were obtained in order to understand the legal settings in Switzerland, England and Wales, and the U.S. All articles, reports, and policy documents published in English and German between 1774 to June 2012 were included for analysis. Using a comparative approach, an outline was completed to distinguish positive policies in this area. Regulatory approaches were investigated through evaluations of soft laws applicable in Europe and U.S. Supreme Court judgements. RESULTS: Even though several documents could be interpreted as guaranteeing adequate health care for ageing prisoners, there is no specific regulation that addresses this issue completely. The Vienna International Plan of Action on Ageing contributes the most by providing an in-depth analysis of the health care needs of older persons. Still, critical analysis of retrieved documents reveals the lack of specific legislation regarding the health care for ageing prisoners. CONCLUSION: No consistent regulation delineates the provision of health care for ageing prisoners. Neither national nor international institutions have enforceable laws that secure the precarious situation of older adults in prisons. To initiate a change, this work presents critical issues that must be addressed to protect the right to health care and well-being of ageing prisoners. Additionally, it is important to design legal structures and guidelines which acknowledge and accommodate the needs of ageing prisoners.

Information technologies and communication between parents and children

This is an exploratory study that aims, on the one hand, to examine in more detail how children between 12 and 16 years of age use different audiovisual technologies, what they feel and think when using them, and whom they like to speak to about such experiences. On the other hand, we look more deeply into the interactions between adults and children, particularly between parents and their children, in relation to these technologies when children use them at home or in other places. We analysed responses to questionnaires with several common items, administered separately to parents and children. Children’s responses reflect an important level of dissatisfaction when talking with different adults about media activities. Our findings support the thesis that more and more children socialise through new information and communication technologies with little or no recourse to adult criteria, giving rise to the emergence of specific children’s cultures. Crossing of the responses of parents and those of their own children shows us which aspects of media reality adults overestimate or underestimate in comparison to children, and to what degree certain judgements coincide and differ between generations. The results can be applied to the improvement of relations between adults and adolescents, taking advantage of adolescents’ strong motivation to engage in activities using audiovisual media

Accelerated publication versus usual publication in 2 leading medical journals.

BACKGROUND: A number of medical journals have developed policies for accelerated publication of articles judged by the authors, the editors or the peer reviewers to be of special importance. However, the validity of these judgements is unknown. We therefore compared the importance of articles published on a "fast track" with those published in the usual way. METHODS: We identified 12 "case" articles--6 articles from the New England Journal of Medicine that were prereleased on the journal's Web site before publication in print and 6 "fast-tracked" articles from The Lancet. We then identified 12 "control" articles matched to the case articles according to journal, disease or procedure of focus, theme area and year of publication. Forty-two general internists rated the articles, using 10-point scales, on dimensions addressing the articles' importance, ease of applicability and impact on health outcomes. RESULTS: For each dimension, the mean score for the case articles was significantly higher than the mean score for the control articles: importance to clinical practice 7.6 v. 7.1 respectively (p = 0.001), importance from a public health perspective 6.5 v. 6.0 (p < 0.001), contribution to advancement of medical knowledge 6.2 v. 5.8 (p < 0.001), ease of applicability in practice 7.0 v. 6.5 (p < 0.001), potential impact on health outcomes 6.5 v. 5.9 (p < 0.001). Despite these general findings, in 5 of the 12 matched pairs of articles the control article had a higher mean score than the case article across all the dimensions. INTERPRETATION: The accelerated publication practices of 2 leading medical journals targeted articles that, on average, had slightly higher importance scores than similar articles published in the usual way. However, our finding of higher importance scores for control articles in 5 of the 12 matched pairs shows that current journal practices for selecting articles for expedited publication are inconsistent.

Clairvoyance de l'utilité et de la désirabilité sociales dans les situations d'évaluation

Résumé Le concept de clairvoyance normative (Py & Somat, 1991), qui a vu le jour dans la continuité des études sur la norme d'internalité (Beauvois, 1984), traduit la connaissance du caractère normatif ou contre-normatif d'un type de comportements ou d'un type de jugements. Un certain nombre de recherches semble alors attester que la clairvoyance normative participe à l'obtention d'une évaluation positive. Toutefois, ces différentes recherches font toutes fi de l'idée qu'il existerait deux dimensions de la valeur sociale : l'utilité sociale et la désirabilité sociale. La prise en compte de ces deux dimensions, surtout si l'on admet que les normes sociales ne renvoient pas toutes à la même dimension (Beauvois, 1995 ; Dubois & Beauvois, 2005 ; Dubois, 2005), vient alors quelque peu compliquer le modèle liant clairvoyance normative et évaluation positive car elle suggère que la clairvoyance de certaines normes aidera avant tout à être bien évalué sur le plan de l'utilité sociale alors que la clairvoyance d'autres normes participera davantage à être évalué favorablement sur le plan de la désirabilité sociale. Ces réflexions ont été à la base de ce travail de thèse et ont conduit à la réalisation de notre première étude. Les quelques résultats inattendus que nous avons obtenus nous ont cependant incité par la suite à reconsidérer la pertinence de rattacher la notion de clairvoyance à certains types de contenu (internalité, autosuffisance, etc.), ce qui nous a amené à la proposition de deux nouvelles notions : la clairvoyance de l'utilité sociale et la clairvoyance de la désirabilité sociale. C'est dans l'optique de valider cette proposition que deux nouvelles études ont alors été réalisées. Si celles-ci appuient dans leur ensemble l'idée que les clairvoyances de l'utilité et de la désirabilité sociales seraient des indicateurs plus performants d'une évaluation sociale positive que ne le seraient les clairvoyances des normes sociales de jugement, elles n'ont néanmoins pas manqué de soulever de nouvelles questions. Cela nous a ainsi mené, dans un troisième temps, à nous interroger sur ce qui détermine la valeur en jeu dans une situation d'évaluation. Nos trois dernières études ont été construites dans ce dessein et ont participé, en conclusion de ce travail, à étayer l'idée que la clairvoyance de la valeur sociale des jugements ne permettrait l'obtention d'une évaluation positive que si celle-ci va de pair avec une certaine clairvoyance de la valeur sociale des éléments constitutifs de la situation d'interaction. Abstract The concept of normative clearsightedness (Py & Somat, 1991), born in continuity with studies on the norm of internality (Beauvois, 1984), reflects the knowledge of the normative or counter-normative nature of a type of behaviour or a type of judgement. Several researches appear to show that normative clearsightedness helps to obtain a positive evaluation. However, none of these researches takes into account the idea that there might be two dimensions of social value: social utility and social desirability. Considering those two dimensions, especially if we accept that not all social norms refer to the same dimension (Beauvois, 1995; Dubois & Beauvois, 2005; Dubois, 2005), somehow complicates the model linking normative clearsightedness with a positive evaluation. It suggests indeed that while clearsightedness of some norms will help first of all to get a good evaluation on the dimension of social utility, clearsightedness of other norms will help above all to get a good evaluation on the dimension of social desirability. These considerations were the foundation of this work and led to our first study. However, we reached some unexpected results that prompted us thereafter to reconsider the pertinence to attach the notion of clearsightedness to particular types of content (internality, self-sufficiency, etc.), which led us to propose two new notions: clearsightedness of social utility and clearsightedness of social desirability. Two new studies were thus executed to challenge this proposal. While these researches support as a whole that clearsightedness of social utility and social desirability are better indicators of positive evaluation than clearsightedness of social norms of judgement, they also raised new questions, which led us, in a third time, to wonder about what will determine the dominating social value in an evaluative situation. Our last three studies were designed to this purpose and helped to support the idea, in conclusion of this work, that the clearsightedness of the social value of judgements would bring a positive evaluation only if this clearsightedness is combined with a kind of clearsightedness of the social value of elements constituting the interaction's situation.
