OBJECTIVES: Our analysis assessed the impact of information on patients' preferences in prescription versus over-the-counter (OTC) delivery systems. METHODS: A contingent valuation (CV) study was implemented, randomly assigning 534 lay people into the receipt of limited or extended information concerning new influenza drugs. In each information arm, people answered two questions: the first asked about willingness to pay (WTP) for the new prescription drug; the second asked about WTP for the same drug sold OTC. RESULTS: We show that WTP is higher for the OTC scenario and that the level of information plays a significant role in the evaluation of the OTC scenario, with more information being associated with an increase in the WTP. In contrast, the level of information provided has no impact on WTP for prescription medicine. Thus, for the kind of drug considered here (i.e. safe, not requiring medical supervision), a switch to OTC status can be expected to be all the more beneficial, as the patient is provided with more information concerning the capability of the drug. CONCLUSIONS: Our results shed light on one of the most challenging issues that health policy makers are currently faced with, namely the threat of a bird flu pandemic. Drug delivery is a critical component of pandemic influenza preparedness. Furthermore, the congruence of our results with the agency and demand theories provides an important test of the validity of using WTP based on CV methods.

Colonization is likely to be more successful for species with an ability to self-fertilize and thus to establish new populations as single individuals. As a result, self-compatibility should be common among colonizing species. This idea, labelled 'Baker's law', has been influential in discussions of sexual-system and mating-system evolution. However, its generality has been questioned, because models of the evolution of dispersal and the mating system predict an association between high dispersal rates and outcrossing rather than selfing, and because of many apparent counter examples to the law. The contrasting predictions made by models invoking Baker's law versus those for the evolution of the mating system and dispersal urges a reassessment of how we should view both these traits. Here, I review the literature on the evolution of mating and dispersal in colonizing species, with a focus on conceptual issues. I argue for the importance of distinguishing between the selfing or outcrossing rate and a simple ability to self-fertilize, as well as for the need for a more nuanced consideration of dispersal. Colonizing species will be characterized by different phases in their life pattern: dispersal to new habitat, implying an ecological sieve on dispersal traits; establishment and a phase of growth following colonization, implying a sieve on reproductive traits; and a phase of demographic stasis at high density, during which new trait associations can evolve through local adaptation. This dynamic means that the sorting of mating-system and dispersal traits should change over time, making simple predictions difficult.

The De calcatione demonum seu malignorum spirituum was written in 1457 by Nicolas Jacquier, one year before his most famous work, the Flagellum hereticorum fascinariorum. The De calcatione offers initial reflections by the Burgundian dominican inquisitor on diabolical modes of actions directed at human beings and on the means at the disposal of priests and their faithful to control, expel, and trample (calcare) them. This relatively unknown text is produced at a time when purely demonological issues are linked to those on diabolical witchcraft and the sabbath. The author tries in particular to promote the idea of trampling demons, which is understood as their punishment. Now vanquished, demons are compelled to serve divine truth. In a climate of skepticism about the need to fight withcraft, the De calcatione offers an interesting reflexion about the truth status of diabolical and heretical discourses when submitted to divine power. This reflexion is based on the model of the positive figure of the possessed from exampla and from dominican hagiography. The treatise therefore aims to counter the tradition of the Episcopi canon which argues for the illusory nature of demons. Instead, it offers an argument about the reality of their actions on the occasion of the sabbat

« Il était une fois... Cette thèse aborde le lien entre l'expression théâtrale et son utilisation clinique dans la psychothérapie d'enfants. Partant du questionnement sur les origines du théâtre et de la thérapie dans l'histoire de l'humanité, donc du substrat « archaïque » de l'homme et de sa relation à l'art scénique, la première partie développe une réflexion autour des rituels, du chamanisme et de la notion du soin. Purement théorique, elle soulève cependant la question de l'identité de l'Homme dans les sociétés postmodernes et traite de la thématique du développement psychique de l'enfant au sein de notre société occidentale ainsi que des souffrances qui en amènent certains vers les consultations psychologiques La partie principale s'articule autour de six histoires cliniques d'enfants suivis en psychothérapie expressive, récits dans lesquels la médiation théâtrale et corporelle devient 1 outil central du soin. En se développant sur la base d'une mise en narration des histoires imaginaires des enfants qui reflètent leurs angoisses archaïques, 1 univers thérapeutique prend alors la forme d'une scène psychique ouvrant a la symbolisation à travers le jeu théâtral. Parallèlement à la description de ce dispositif, une élaboration est menée autour des échanges transférentiels et con re transferentiels ainsi que sur la position du thérapeute - son rôle de « médium malleable » - dans la relation à l'Autre qui se tisse dans un « ici et maintenant » de la rencontre psychotherapeutic. Grâce à cet univers ludique s'enracinant dans son vécu psycho-fantasmatique, l'enfant devient l'acteur agissant de sa propre transfonnation : une évolution du monstre archaïque en sa créature symbolique. -- « Once upon a time... » This thesis treats the link between theatrical expression and its clinical use in children s psychotherapy. Originating from interrogations on the origins of theatre and therapy in the history of mankind, therefore the « archaic » substratum of Man and his relation to the theatre. The first part develops a reflection around rituals shamanism and the notion of care. In a purely theoretical way, it brings up the ques ions of Man's identity in post-modern societies and deals with the psychic development of children in western society and the pains that lead some to seek for psychological consultations. The main part hinges on six clinical stories of children in expressive psychotherapy, m which theatrical and coiporal mediation become the main tool within he treatment. By putting into narration, the children's imaginary stories that reflect their archaic anxiety, therapy takes in the shape of a psychic scene, which opens to symbolization through acting. At the same time, an elaboration is lead on transferential and counter-transferential exchanges as on the therapists position - his role as « malleable medium » - his interactions with others as a «here and now » in the psychotherapeutic encounter. Thanks to this playful universe, which emerges from his psycho-fantasy past, the child becomes the willing actor of his own transformation: the evolution of the archaic monster into its symbolical creature.

Glucose homeostasis as well as homeostatic and hedonic control of feeding is regulated by hormonal, neuronal, and nutrient-related cues. Glucose, besides its role as a source of metabolic energy, is an important signal controlling hormone secretion and neuronal activity, hence contributing to whole-body metabolic integration in coordination with feeding control. Brain glucose sensing plays a key, but insufficiently explored, role in these metabolic and behavioral controls, which when deregulated may contribute to the development of obesity and diabetes. The recent introduction of innovative transgenic, pharmacogenetic, and optogenetic techniques allows unprecedented analysis of the complexity of central glucose sensing at the molecular, cellular, and neuronal circuit levels, which will lead to a new understanding of the pathogenesis of metabolic diseases.

Since Ehrlich & Raven's seminal paper 50 years ago, coevolution has been seen as a major driver of species diversification. Here, we review classical and more recent case studies on the coevolution of plants and associated insects, to examine whether the coevolutionary component holds as an explanation of their current diversity. We discuss the main dogmas in coevolution and argue that coevolutionary processes should not be considered as major drivers of diversification in plants and insects. Instead, we suggest that coevolution essentially occurs through relatively short 'interludes', making the pattern difficult to detect. We also criticize the use of comparative phylogenetics to investigate coevolutionary processes, as coevolution may not necessarily produce congruent phylogenies among interacting lineages and, in turn, other processes may produce patterns of codivergence. Finally, we propose new lines of investigation for future research.

PROBLEM: Truth-telling is an important component of respect for patients' self-determination, but in the context of breaking bad news, it is also a distressing and difficult task. INTERVENTION: We investigated the long-term influence of a simulated patient-based teaching intervention, integrating learning objectives in communication skills and ethics into students' attitudes and concerns regarding truth-telling. We followed two cohorts of medical students from the preclinical third year to their clinical rotations (fifth year). Open-ended responses were analysed to explore medical students' reported difficulties in breaking bad news. CONTEXT: This intervention was implemented during the last preclinical year of a problem-based medical curriculum, in collaboration between the doctor-patient communication and ethics programs. OUTCOME: Over time, concerns such as empathy and truthfulness shifted from a personal to a relational focus. Whereas 'truthfulness' was a concern for the content of the message, 'truth-telling' included concerns on how information was communicated and how realistically it was received. Truth-telling required empathy, adaptation to the patient, and appropriate management of emotions, both for the patient's welfare and for a realistic understanding of the situation. LESSONS LEARNED: Our study confirms that an intervention confronting students with a realistic situation succeeds in making them more aware of the real issues of truth-telling. Medical students deepened their reflection over time, acquiring a deeper understanding of the relational dimension of values such as truth-telling, and honing their view of empathy.

This article examines the process of neoliberalization in the Shenzhen special economic zone in Guangdong province, China. Building on the case study of a former peasant and almost single-lineage village that has become a part of Shenzhen city, I show how neoliberal principles aimed at advancing the transition to capitalism are combined with and countered by other ethical traditions. Owing to the long-standing conception of the lineage as an enterprise, the maintenance of the lineage structure in the transformation of the rural collectives has offered fertile ground for the emergence of a local capitalist coalition. Yet the current discourses on the necessity of obliterating the remains of the collective economy and introducing individual ownership run counter to the collectivist values of the lineage-village community and the embeddedness of its economy in kinship and territorial ties. I further illustrate this discordance by the way in which the villagers managed to save their founding ancestor's gravesite following government requests to clear the land by removing tombs. These policies form a complex blend of state interventions in the economy, neoliberal governance and Confucian principles.

BACKGROUND: The use of a robotic surgical system is claimed to allow precise traction and counter-traction, especially in a narrow pelvis. Whether this translates to improvement of the quality of the resected specimen is not yet clear. The aim of the study was to compare the quality of the TME and the short-term oncological outcome between robotic and laparoscopic rectal cancer resections. METHODS: 20 consecutive robotic TME performed in a single institution for rectal cancer (Rob group) were matched 1:2 to 40 laparoscopic resections (Lap group) for gender, body mass index (BMI), and distance from anal verge on rigid proctoscopy. The quality of TME was assessed by 2 blinded and independent pathologists and reported according to international standardized guidelines. RESULTS: Both samples were well matched for gender, BMI (median 25.9 vs. 24.2 kg/m(2), p = 0.24), and level of the tumor (4.1 vs. 4.8 cm, p = 0.20). The quality of the TME was better in the Robotic group (complete TME: 95 vs. 55 %; p = 0.0003, nearly complete TME 5 vs. 37 %; p = 0.04, incomplete TME 0 vs. 8 %, p = 0.09). A trend for lower positive circumferential margin was observed in the Robotic group (10 vs. 25 %, p = 0.1). CONCLUSIONS: These results suggest that robotic-assisted surgery improves the quality of TME for rectal cancer. Whether this translates to better oncological outcome needs to be further investigated.
