Pheomelanin-based coloration and the ability to cope with variation in food supply and parasitism.

Although gene by environment interactions may play a key role in the maintenance of genetic polymorphisms, little is known about the ecological factors involved in these interactions. We investigated whether food supply and parasites can mediate covariation between the degree of adult pheomelanin-based coloration, a heritable trait, and offspring body mass in the tawny owl (Strix aluco). We swapped clutches between nests to allocate genotypes randomly among environments. Three weeks after hatching, we challenged the immune system of 80 unrelated nestlings with either a phytohemagglutinin (PHA) or a lipopolysaccharide, surrogates of alternative parasites, and then fed them ad lib. or food-restricted them during the following 6 days in the laboratory. Whatever the immune challenge, nestlings fed ad lib. converted food more efficiently into body mass when their biological mother was dark pheomelanic. In contrast, food-restricted nestlings challenged with PHA lost less body mass when their biological mother was pale pheomelanic. Nestling tawny owls born from differently melanic mothers thus show differing reaction norms relative to food availability and parasitism. This suggests that dark and pale pheomelanic owls reflect alternative adaptations to food availability and parasites, factors known to vary in space and time.

Melanin-specific life-history strategies.

Abstract The maintenance of genetic variation is a long-standing issue because the adaptive value of life-history strategies associated with each genetic variant is usually unknown. However, evidence for the coexistence of alternative evolutionary fixed strategies at the population level remains scarce. Because in the tawny owl (Strix aluco) heritable melanin-based coloration shows different physiological and behavioral norms of reaction, we investigated whether coloration is associated with investment in maintenance and reproduction. Light melanic owls had lower adult survival compared to dark melanic conspecifics, and color variation was related to the trade-off between offspring number and quality. When we experimentally enlarged brood size, light melanic males produced more fledglings but in poorer condition, and they were less often recruited in the local breeding population than those of darker melanic conspecifics. Our results also suggest that dark melanic males allocate a constant effort to raise their brood independently of environmental conditions, whereas lighter melanic males finely adjust reproductive effort in relation to changes in environmental conditions. Color traits can therefore be associated with life-history strategies, and stochastic environmental perturbation can temporarily favor one phenotype over others. The existence of fixed strategies implies that some phenotypes can sometimes display a "maladapted" strategy. Long-term population monitoring is therefore vital for a full understanding of how different genotypes deal with trade-offs.

Information and risk management during the first trimester care for pregnant women: Some reflections about the ethical challenges and the legal framework in Switzerland. [L'information et la gestion des risques dans le suivi de la grossesse lors du 1er trimestre : quelques réflexions sur le défi éthique et le cadre légal en Suisse.]

The progress in prenatal medicine raises complex questions with respect to the physician-patient relationship. The physician needs to reconcile medical aspects, ethical principles as well as judicial norms. Already, during the first trimester, the physician has to put into practice the schedule combining for each individual pregnancy physical, laboratory and other appropriate exams. Physicians are under the obligation to inform in a clear and comprehensive way without creating unnecessary anxiety for their patients. Legal requirements include informed consent, the respect for the patient's right to self-determination, and compliance with the Swiss federal law on genetic testing, especially with its articles on prenatal screening and diagnosis. This article discusses the complexity of obstetrical practice when it comes to delivering adequate information within the scope of ethical and legal requirements in Switzerland. L'évolution de la médecine prénatale soulève des enjeux complexes dans la relation médecin-patient. Il s'agit de concilier à la fois les aspects médicaux, les principes éthiques et les normes juridiques. Dès le premier trimestre de la grossesse le médecin doit poser le cadre du suivi et des examens appropriés pour chaque grossesse. Son devoir est d'informer de manière claire et précise sans inquiéter inutilement, en respectant l'exigence légale d'un consentement éclairé et plus largement le droit de la patiente à l'autodétermination ainsi que le cadre de la loi fédérale suisse sur l'analyse génétique humaine dans le domaine du dépistage et du diagnostic prénatal. Cet article discute de la complexité de l'information et de l'application des principes éthiques et légaux dans la pratique obstétricale en Suisse.

Women in leadership: Three essays

GENDER EMPOWERMENT: EFFECTS OF GODS, GEOGRAPHY, AND GDP¦Fenley, M., & Antonakis, J.¦ABSTRACT¦We examined the determinants of women's empowerment in the economy and political leadership in 178 countries. Given the androcentric nature of most religions, we hypothesized that high degrees of country-level theistic belief create social conditions that impede the progression of women to power. The dependent variable was the Gender Empowerment index of the United Nations Development Program, which captures the participation of women in political leadership, management, and their share of national income. Controlling for GDP per capita as well as the fixed-effects of the dominant type of religion and legal origin and instrumenting all endogenous variables with geographic or historical variables, our results show that atheism has a significant positive effect on gender empowerment. These results are driven by the rule of law, which in addition to being a catalyst for economic development, appears to crowd-out the informal regulation of behavior due to religious norms.¦DEVELOPING WOMEN LEADERS: COMPARING A TRANSFORMATIONAL AND A CHARISMATIC LEADERSHIP INTERVENTION¦Fenley, M., Jacquart, P., & Antonakis, J.¦ABSTRACT¦Along with a gender imbalance in leadership role occupancy, most leadership interventions have been conducted with samples of men. We conducted an experiment wherein we assigned female participants (n = 38, mean age = 35 years) to one of two conditions: Transformational (i.e., "standard") leadership training or charismatic leadership training. The two interventions were essentially equivalent, except that we also focused on developing the "charismatic leadership tactics" (e.g., rhetorical skills) of participants in the charismatic condition. After the interventions, we randomly assigned participants into problem-solving teams that required extensive interaction. Each team had an equal number of participants having received transformational training or charismatic training. At the end of the team exercises, participants rated each of their team members on a leadership prototypicality measure. Results indicated that those who received charismatic training scored higher (a) on prototypicality (standardized  = .42) and (b) on a test of declarative knowledge of charismatic rhetorical strategies (i.e., a manipulation check, standardized  = .76). Furthermore, the score on the test fully mediated the effect of the treatment on prototypicality (standardized indirect  = .32). We discuss the importance and practical implications of these results.¦CHANGING ATTITUDES TOWARDS WOMEN IN A MALE SEX-TYPE WORK ENVIRONMENT: EVIDENCE FROM A FIELD EXPERIMENT IN EUROPEAN ATHLETICS¦Fenley, M.¦ABSTRACT¦Most sports organizations have a similar gender gap in leadership as do the majority of non-sport organizations. Women's careers sputter somewhere at coaching level positions and few women obtain top leadership positions. Greater awareness of gender inequalities in general, and in leadership in particular, could decrease gender discrimination and increase women's presence at upper levels. The goal of this study was to evaluate the impact of an intervention using an online gender awareness exercise. Participants (n = 1,001 participants, n = 32 countries) were randomly assigned to one of eight conditions in a 2 (a discriminating perspective-taking story or a non-discriminating perspective-taking story) by 2 (gender quiz or no gender quiz) by 2 (diversity quiz or no diversity quiz) factorial design. The results show that the online perspective taking exercise changed initial sexist attitudes. Participants having taken a diversity quiz had less sexist attitudes (as measured by the Modern- and Old-fashioned sexism scale) than did participants who did not take the diversity quiz (irrespective of perspective-taking story). The combination of having taken a diversity quiz with a gender quiz had the biggest impact on attitudes for the non-discriminating story.

Beyond the silence : institutional racism, social welfare and swiss citizenship

Cette thèse doctorale étudie le rôle de la citoyenneté Suisse et le modèle libérale de l'Etat social dans la production du racisme institutionnel au sein des services sociaux en Suisse. Cette thèse pose la question comment le régime de la citoyenneté Suisse rend possible et contraint les travailleurs sociaux à racialiser et discriminer leur clients avec des différences culturelles alors que les normes de l'aide sociale (normes de CSIAS) ne prévoient pas des traitements différentialistes selon la culture ou l'origine. Le modèle théorique du racisme institutionnel développé se passe sur une approche néo- institutionaliste et des ethnie and racial studies, prenant en compte le niveau individuel, collectif et institutionnel. En incluant ces deux approches, on dépasse le déterminisme des structuralistes dans les études sur le racisme institutionnel. Cette recherche qualitative montre que les travailleurs sociaux utilisent les ressources de la citoyenneté Suisse, de l'Etat social Suisse et leur expériences personnelles quand ils interagissent avec des clients. En plus, cette thèse démontre que le workfare logique en combinaison avec l'idée de l'assimilation culturelle rend possible la production d'un discours sur la nécessité de mériter d'être un membre de la communauté nationale et d'accéder à l'aide sociale. Cette compréhension néo-libérale de la citoyenneté renforce et légitime les travailleurs sociaux de racialiser et pratiquer la discrimination à l'égard de leurs clients et les rend incapable de développer une réflexivité critique. Toutefois, cette thèse montre également que les travailleurs sociaux produisent du travail social interculturel s'ils ont pu développer une telle réflexivité critique dans les institutions de l'aide sociale qui mettent en avant une conception "individuelle" de l'aide sociale.-Cette thèse vise à aller au-delà du silence qui constitue les débats publiques et la recherche sur le racisme au sein des institutions publiques en Suisse. - This thesis questions the role of the Swiss citizenship regime and the Swiss liberal social welfare model in the production of institutional racism in social services in Switzerland. Considering the absence of intercultural formal guidelines in the norms of social welfare (SKOS norms), this research investigates how the Swiss citizenship regime constrains and enables social workers to racialise and discriminate against their clients with cultural differences. This thesis develops a model of institutional racism, taking into account ethnic and racial studies and a neo-institutionalist approach on institutions, addressing the individual, collective and institutional level. In this framework, this thesis allows to overcome the structuralist determinism in the studies on institutional racism. Based on a qualitative inquiry, this research shows that social workers use the resources from the Swiss citizenship regime, social welfare model and their personal experiences when they interact with their clients. This study also shows that the workfare logic in combination with the idea of cultural assimilation enables to produce a discourse on deserving social welfare and earning membership to the national community. This neo-liberal citizenship understanding reinforces and legitimises social workers to racialise and discriminate against their clients and hinders them to develop critical reflexivity. However, this thesis also shows that social workers are able to produce intercultural social work when they could develop such a reflexivity in social services with an "individual" social welfare conceptions. This thesis aims to go beyond a persisting silence regarding public debates and research on racism in public institutions in Switzerland.

Toxicity assessment of refill liquids for electronic cigarettes.

We analyzed 42 models from 14 brands of refill liquids for e-cigarettes for the presence of micro-organisms, diethylene glycol, ethylene glycol, hydrocarbons, ethanol, aldehydes, tobacco-specific nitrosamines, and solvents. All the liquids under scrutiny complied with norms for the absence of yeast, mold, aerobic microbes, Staphylococcus aureus, and Pseudomonas aeruginosa. Diethylene glycol, ethylene glycol and ethanol were detected, but remained within limits authorized for food and pharmaceutical products. Terpenic compounds and aldehydes were found in the products, in particular formaldehyde and acrolein. No sample contained nitrosamines at levels above the limit of detection (1 μg/g). Residual solvents such as 1,3-butadiene, cyclohexane and acetone, to name a few, were found in some products. None of the products under scrutiny were totally exempt of potentially toxic compounds. However, for products other than nicotine, the oral acute toxicity of the e-liquids tested seems to be of minor concern. However, a minority of liquids, especially those with flavorings, showed particularly high ranges of chemicals, causing concerns about their potential toxicity in case of chronic oral exposure.

In this chapter, we examine the multiple dimensions of declarations of fertility in-tention in order to provide a critical reading of currently used indicators of the childbearing decision-making process. Using a qualitative approach, we pay atten-tion to the complexity of the process through which individuals make (or fail to make) plans regarding their reproductive future. The data are a series of compara-ble in-depth interviews conducted in a number of European countries with varying fertility levels, and differing normative and institutional contexts. First, we ana-lyze the meanings that respondents attribute to their childbearing intentions, pay-ing particular attention to uncertain intentions that are often underanalyzed. Se-cond, we study the ways in which individuals vary in holding to their intentions over time, and consider why they might change their minds, even over relatively short periods of time. Third, we examine how several aspects of the larger social context (attitudes towards having children, family policy, norms related to the di-vision of labor, norms about the timing of children) shape fertility intentions.

Starting from the mid-1960s, family and fertility patterns in Europe underwent fundamental changes. Social scientists have increasingly turned to intergenerational models to explain such changes. This paper deals with one important intergenerational dimension of fertility, namely the transmission of normative beliefs about childbearing choices. Normative beliefs are important determinants of fertility behavior. While norms are learnt and internalized throughout the life course, primary socialization of children within the family and role modeling are important mechanism to ensure norm transmission. Interaction with family members in adult life may reinforce the effects of early socialization and role modeling. The paper focuses on the ways in which mothers and daughters make sense of normative beliefs about childbearing. I draw on set of semi-structured interviews with childless women in reproductive ages and their mothers, collected in Italy between 2004 and 2006. First, I provide a micro-level descriptive analysis of normative beliefs about childbearing norms in mother-daughter dyads. Second, linking these descriptive analyses to the biography of specific dyads, I identify patterns of continuity and discontinuity in the social meaning of children and their fertility outcomes.

Two-dimensional probabilistic inversion of plane-wave electromagnetic data: Methodology, model constraints and joint inversion with electrical resistivity data

Probabilistic inversion methods based on Markov chain Monte Carlo (MCMC) simulation are well suited to quantify parameter and model uncertainty of nonlinear inverse problems. Yet, application of such methods to CPU-intensive forward models can be a daunting task, particularly if the parameter space is high dimensional. Here, we present a 2-D pixel-based MCMC inversion of plane-wave electromagnetic (EM) data. Using synthetic data, we investigate how model parameter uncertainty depends on model structure constraints using different norms of the likelihood function and the model constraints, and study the added benefits of joint inversion of EM and electrical resistivity tomography (ERT) data. Our results demonstrate that model structure constraints are necessary to stabilize the MCMC inversion results of a highly discretized model. These constraints decrease model parameter uncertainty and facilitate model interpretation. A drawback is that these constraints may lead to posterior distributions that do not fully include the true underlying model, because some of its features exhibit a low sensitivity to the EM data, and hence are difficult to resolve. This problem can be partly mitigated if the plane-wave EM data is augmented with ERT observations. The hierarchical Bayesian inverse formulation introduced and used herein is able to successfully recover the probabilistic properties of the measurement data errors and a model regularization weight. Application of the proposed inversion methodology to field data from an aquifer demonstrates that the posterior mean model realization is very similar to that derived from a deterministic inversion with similar model constraints.

Services account for more than 70 percent of GDP in the OECD countries and 50 percent of developing and transition countries. Standardization works to impose common norms on highly differentiated current practice as to availability, provision, and use of services. Some rely on public services, others provide consumer protection or relate to security matters involving liability issues for users and providers alike. Service standards reflect the development of a transnational hybrid authority which exercises a distinct form of market power in the reorganisation of the global capitalist economy towards services.

The conditions for the reproduction of the SAGUAPAC water cooperative in the city of Santa Cruz de la Sierra, Bolivia : discourse analysis

The SAGUAPAC cooperative in the city of Santa Cruz de la Sierra (Eastern Bolivia) is regularly presented as an example of cooperative successes regarding water supply and sanitation. Its efficiency, both economic and technical, is widely considered as the main reason for its attractiveness. However, without denying its importance, we show, through a discourse analysis from and about SAGUAPAC in local media, that moral and non-instrumental factors are crucial in the reproduction of the cooperative. These factors create attachment and affection toward the cooperative, through a storytelling using a four-dimensional rhetoric (mythification, identification, emotionalisation and personification). This storytelling technique, internalized in the local media discourse and materializing the so-called new spirit of capitalism, exploits the affects and instrumentalisation of local myths and legends, as well as the 'camba' ethnic identity. In that, it tends to retain SAGUAPAC members and to canvass new ones, by providing them with recognition in their quality of local community members. However, the mobilisation of social norms and power hierarchies might end up reinforcing the social exclusion of Andean non-camba immigrants, inspite of an a priori inclusive and democratic organisation.

Structuration du raconter et évaluation de la racontabilité dans l'entretien médiatique

In this study, we assume that the organisation of storytelling activity is sensitive to emerging norms and, specifically, to what is worth telling from a participant's perspective. We associate the methods of conversation analysis with a labovian approach to oral narratives and examine how storytelling is collaboratively and sequentially built during a radio interview parody. After discussing the relevance of parodic data to understand how media practitioners see their own practices (here: telling a story during a media interview), we provide a detailed analysis of a deviant case by considering the relations between structuring the telling and evaluating the tellability. The analysis leads to show what kinds of interactional resources are used to accomplish the activity: for instance, concurrent topic formulations, shared configurations of grammatical constructions, adjacency pairs. The study also points out how competing agendas can configure the activity in dissimilar ways. Eventually, it underlines the issues of being the interviewee and the storyteller at the same time.

Naturaliser la procréation médicalement assistée : sens commun et représentations en dialogue

La constante évolution des biotechnologies de la procréation médicalement assistée (PMA) introduit des nouveautés qui perturbent les représentations de la famille et du « naturel » de la procréation notamment. Ces nouveautés engendrent des préoccupations aussi bien sociales qu'individuelles sur la légitimité et les conditions du recours à la PMA. Partant d'une approche dialogique de la communication, du langage et de la cognition ainsi que de la théorie des représentations sociales, nous faisons l'hypothèse que ces perturbations sont traitées différemment selon l'activité communicative dans laquelle les individus sont engagés. Nous avons alors travaillé à partir de deux corpus de données relevant d'un type d'activité communicative différent : un corpus de presse, de l'ordre d'un discours générique, portant sur la grossesse dite « tardive » (post-ménopause) et un corpus d'entretiens de recherche, de l'ordre d'un discours singulier, avec des couples qui ont recouru à la PMA, et portant sur la cryoconservation des zygotes. Nous appuyant sur les méthodes de l'analyse thématique et de l'analyse de discours, nous centrons notre examen sur les représentations sociales de la maternité (corpus de presse) et du « naturel » (corpus d'entretiens). Nous analysons ce que ces discours permettent d'accomplir socialement, étudions le rapport qu'ils établissent à l'ordre social et symbolique et interrogeons leurs fonctions en termes de processus de « naturalisation » de la PMA. Nos résultats montrent que les nouveautés de la PMA forcent les individus à se (re)positionner dans le champ des valeurs et des normes, lis montrent aussi que, dans ce contexte, les représentations sociales existantes sont mobilisées de différentes manières en fonction des visées argumentatives poursuivies. Ceci impliquant, par ailleurs, si ce n'est une transformation, du moins un renouvellement des représentations. Ils indiquent en outre que, bien que le discours de presse et celui des entretiens ne servent pas exactement les mêmes objectifs, leurs effets de « naturalisation » de la PMA sont comparables en termes de (re)construction de la norme. D'un point de vue dialogique, ils permettent aussi d'avancer que les polémiques sociales et individuelles sont non seulement articulées mais se co-constituent. Ils témoignent aussi du fait que la référence au « naturel » renvoie, plus qu'à un problème de perturbation de la « nature », à l'idée d'une menace de l'ordre social et symbolique. De ce point de vue, les réflexions sur les pratiques de PMA méritent d'être menées par la psychologie sociale et les sciences humaines et sociales plus largement. -- The constant evolution of biotechnologies of medically assisted procreation (MAP) introduces novelties that disturb representations of the family and, notably, of what is considered « natural » in procreation. These novelties give rise to social and individual questions about the legitimacy and the conditions of the use of MAP. Drawing upon a dialogical approach to communication, language and cognition, as well as social representations theory, a hypothesis is advanced that these disturbances are handled differently, depending on the communicative activity individuals are engaged in. Two corpuses of data, representing different communicative activity types, were used: a press corpus, reflecting a generic discourse on "late" pregnancy (post-menopause), and a research interviews corpus, reflecting particular discourses developed by couples who used MAP and have cryopreserved zygotes. Using methods of thematic and discourse analysis, the study focuses on social representations of pregnancy (press corpus) and of the "natural" (interviews corpus). The analysis questions what these discourses enable to achieve socially, how they relate to the social and symbolic order, as well as their function in "naturalising" MAP. The results show that MAP novelties force individuals to (re)position themselves in the field of values and norms. They also show that, in this context, existing social representations are mobilised in different ways depending on the argumentative aims that are being pursued. This implies, if not a transformation, at minimum a renewal of representations. Additionally the results indicate that, although press and interviews discourses might not serve the same aims, their effects on "naturalising" MAP are comparable in terms of (re)constructing the norm. From a dialogical perspective, the findings also allow us to argue that social and individual polemics are not only articulated with one another but are effectively co-constituted. They also evidence the fact that the reference to the "natural" brings forth, more than a problem of disturbing "nature", a threat to the social and symbolic order. From this perspective, reflections on MAP practices deserve further attention within social psychology and social and human sciences at large.

Une délicate rencontre entre savoirs autochtones "experts" : enjeux politiques interculturelles dans le domaine de la prévention de la violence à l'égard des femmes kichwa en Amazonie équatorienne

Cette thèse porte sur l'élaboration et la mise en pratique de politiques interculturelles dans le champ de la santé internationale, en se basant sur une ethnographie d'un programme de préven¬tion de la violence de genre dans le canton de Loreto, en Amazonie équatorienne, mis en place par la Croix-Rouge suisse et aujourd'hui géré de concert avec l'Etat équatorien et une organisation kichwa locale. Suivant une approche qui fait varier les échelles d'analyses pour articuler le niveau local, national et international, elle met en évidence les lieux d'intersection et les hiatus entre l'idéal d'interculturalité tel qu'il est conçu «par le haut» et les pratiques qui sont mises en oeuvre au quotidien par des professionnels de la santé et du développement métis équatoriens. Elle révèle ainsi qu'au-delà de l'idéal du respect des « différences culturelles autochtones » et de la symétrie entre les « cultures », les discours et les pratiques de ces professionnels consistent en une entreprise de normalisation et de moralisation des comportements des destinataires kichwa en matière de rapports de genre. Pour affiner ces analyses et dépasser une approche critique de la santé publique, cette thèse explore également les représentations et les pratiques des destinataires - femmes agents de santé et « bénéficiaires » kichwa du programme - en matière de violence et de rapports de genre. Elle montre ainsi que le transfert de normes et de valeurs via la santé publique fait l'objet de mul¬tiples processus d'appropriations, et explore les différentes d'interprétations, de négociations et d'instrumentalisations de la part des destinataires, tant au niveau individuel que collectif. -- Intercultural politics and the prevention of violence against kichwa women in the Ecuadorian Amazon This PhD thesis focuses on the development and application of intercultural policies in the field of international health. It is drawn on an ethnographic fieldwork conducted in canton Loreto, in the Ecuadorian Amazon, about a gender violence prevention program which was set up by the Swiss Red Cross and which is now managed in cooperation with the Ecuadorian State and a local kichwa organization. Following a multiple-scale analysis in order to articulate the local, national and international dynamics, it highlights the intersections and the gaps between, on the one hand, the the institutional prescriptions about the ideal of interculturality and on the other hand, the daily practices of Ecuadorian mestizo health and development profesionals. It reveals that beyond the ideal of respect for «indigenous cultural differences» and of symmetry between «cultures», the discourses and practices of these professionals consist of a normalizing and moralizing enter¬prise concerning the gendered and, more broadly, social behaviors of kichwa «beneficiaries». In order to refine the analysis and to go beyond a critical approach of public health, this thesis also explores the violence and gender relations representations and practices of kichwa women health workers and «beneficiaries», men and women. Thus it shows that the transfer of norms via public health is the subject of multiple processes of appropriation, interpretation, negotiation and instru¬mentalisation both on individual and collective levels by the «beneficiaries».

Décrire une activité verbale et proposer une norme pour enseigner un savoir-faire : l'exemple d'un manuel de storytelling

This paper describes and analyses language norms in a storytelling manual published in the Frenchspeaking part of Switzerland. In the manual, storytelling is conceived as a means of persuasion and thus it appears that an appropriate storytelling should lead to believe or to act. What exactly is "appropriateness" in this specific case? In order to examine this issue, this paper addresses three questions: how storytelling is promoted as an efficient communicative technique; which methods are used to propose and support language norms (by showing "what the storyteller should do" and by saying "how he should do so"); and which are the criteria which define an appropriate story (semantic/formal and functional criteria) and an appropriate telling of the story (communicative and linguistic criteria).
