We report in this paper the result of three experiments on risk, ambiguity and time attitude. The first two differed by the population considered (students vs. general population) while the third one used a different protocol and concerned students and portfolio managers. We find quite a lot of heterogeneity at the individual level. Of principal interest was the elicitation of risk, time and ambiguity attitudes and the relationship among these (model free) measures. We find that on the student population, there (...) is essentially no correlation. A non negligible fraction of the population behaves in an extremely cautious manner in the risk and ambiguity domain. When we drop this population from the sample, the correlation between our measures is also non significant. We also raise three questions linked to measurement of ambiguity attitudes that come out from our data sets. (shrink)

During the eighteenth century, several towns located in what is known today as the Suisse romande were extremely receptive toward scientific culture, and most notably Newtonianism. In this paper I deal with a nine-volume publication of Newton’s Opera Omnia that was planned in Geneva and Lausanne during the late 1730s and 1740s. This publication has not received the attention it deserves. To the best of my knowledge, even an awareness of its existence is lacking in the literature devoted to the (...) reception of Newtonianism. This paper examines the circumstances of the publication of a complete set of all of Newton’s works known at the time, and the motivations of the editors, mathematicians, and publishers who were involved in this editorial enterprise.

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

Task unrelated thought (TUT) refers to thought directed away from the current situation, for example a daydream. Three experiments were conducted on healthy participants, with two broad aims. First, to contrast distributed and encapsulated views of cognition by comparing the encoding of categorical and random lists of words (Experiments One and Two). Second, to examine the consequences of experiencing TUT during study on the subsequent retrieval of information (Experiments One, Two, and Three). Experiments One and Two demonstrated lower levels of (...) TUT and higher levels of word-fragment completion whilst encoding categorical relative to random stimuli, supporting the role of a distributed resource in the maintenance of TUT. In addition the results of all three experiments suggested that experiencing TUT during study had a measurable effect on subsequent retrieval. TUT was associated with increased frequency of false alarms at retrieval (Experiment One). In the subsequent experiments TUT was associated with no advantage to retrieval based on recollection, by manipulating instructions at encoding (Experiment Two), and/or at retrieval (Experiment Three). The implications of the results of all three experiments are discussed in terms of recent accounts of memory retrieval and conscious awareness. (shrink)

The issue of power has become increasingly important within psychiatry, psychotherapy and mental health nursing generally. This paper will suggest that the work of Michel Foucault, the French philosopher and historian, has much to contribute to the discussion about the nature, existence and exercise of power within contemporary mental health care. As well as examining his original and challenging account of power, Foucault's emphasis on the intimate relationship between power and knowledge will be explored within the context of psychiatry (...) and mental health nursing. This is to say that the paper will investigate Foucault's account of how power and knowledge are central to the process by which human beings are ‘made subjects’ and therefore how ‘psychiatric identities’ are produced. In doing so, it will be suggested that Foucault's work can not only make a valuable contribution to contemporary discussions about power and knowledge, but can also provide a significant critique and reconceptualization of the theoretical foundations and associated diagnostic and therapeutic practices of psychiatry and mental health nursing.

Although law is established on a strong presumption that persons younger than a certain age are not competent to consent, statutory age limits for asking children’s consent to clinical research differ widely internationally. From a clinical perspective, competence is assumed to involve many factors including the developmental stage, the influence of parents and peers, and life experience. We examined potential determining factors for children’s competence to consent to clinical research and to what extent they explain the variation in competence judgments.

In order to be able to provide informed, effective and responsive mental health care and to do so in an evidence‐based, collaborative and recovery‐focused way with those who use mental health services, there is a recognition of the need for mental health professionals to possess sophisticated critical thinking capabilities. This article will therefore propose that such capabilities can be productively situated within the context of the work of the French philosopher Michel Foucault, one of the most challenging, innovative and (...) influential thinkers of the 20th century. However, rather than focusing exclusively upon the content of Foucault's work, it will be suggested that it is possible to discern a general methodological approach across that work, a methodological approach that he refers to as “the history of the present.” In doing so, Foucault's history of the present can be understood as a productive, albeit provisional, framework in which to orientate the purpose and process of critical thinking for mental health professionals by emphasizing the need to both historicize and politicize the theoretical perspectives and therapeutic practices that characterize contemporary mental health care.

This second volume in the Counterpoints Series focuses on alternative models of visual-spatial processing in human cognition. The editors provide a historical and theoretical introduction and offer ideas about directions and new research designs.

New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

Understanding the mechanisms and the time and spatial evolution of penumbra following an ischemic stroke is crucially important for developing therapeutics aimed at preventing this area from evolving towards infarction. To help in integrating the available data, we decided to build a formal model. We first collected and categorised the major available evidence from animal models and human observations and summarized this knowledge in a flow-chart with the potential key components of an evolving stroke. Components were grouped in ten sub-models (...) that could be modelled and tested independently: the sub-models of tissue reactions, ionic movements, oedema development, glutamate excitotoxicity, spreading depression, NO synthesis, inflammation, necrosis, apoptosis, and reperfusion. Then, we figured out markers, identified mediators and chose the level of complexity to model these sub-models. We first applied this integrative approach to build a model based on cytotoxic oedema development following a stroke. Although this model includes only three sub-models and would need to integrate more mechanisms in each of these sub-models, the characteristics and the time and spatial evolution of penumbra obtained by simulation are qualitatively and, to some extent, quantitatively consistent with those observed using medical imaging after a permanent occlusion or after an occlusion followed by a reperfusion.

In this article, we present findings from a participatory action research program in France on the exercise of human rights and supported and substitute decision-making, inspired by the United Nations Convention on the Rights of Persons with Disabilities (“CRPD”). Bringing together persons with the lived experience of disability, academics, and health and social care and support professionals, the project used the method of “experience-based construction of public problem” to transform experience into collective expertise. This enabled the exploration of support that (...) persons in vulnerable situations, whose capacity to exercise their human rights has weakened, need to make decisions in their lives and participate meaningfully in public debate. The relationship between the awareness of rights and exercise of rights is discussed. We argue for the need to balance out the positions of different contributors in participatory action research, in a reasoned manner, by recognizing the scientific and citizen-based participation of all partners.

Les relations de la machine et de la pensée sont aussi anciennes qu'énigmatiques, toujours en attente d'une solution. C'est un mythe dont s'abreuve la philosophie. Il est ici repris en fonction de notre conjoncture, la science-fiction avec Matrix, la logique et l'ordinateur avec Turing, enfin l'élaboration théorique avec le cognitivisme et la non-philosophie. Ces essais ont été élaborés dans un même esprit au sein d'une équipe dont les jeunes philosophes partagent le désir commun de renouveler le style philosophique par une (...) discipline de philo-fiction. -/- The relationship between the machine and thought is as old as it is enigmatic, always awaiting a solution. It's a myth that philosophy feeds on. Here it is revisited in the context of our current situation: science fiction with Matrix, logic and the computer with Turing, and theoretical development with cognitivism and non-philosophy. These essays have been drawn up in the same spirit by a team of young philosophers who share a common desire to renew the philosophical style through a discipline of philo-fiction. (shrink)

Marc Pelchat | Résumé : La présente contribution s’intéresse aux défis auxquels se mesure le théologien qui assume la charge d’animer et de diriger une institution de formation théologique, afin de la situer dans l’Église et dans l’Université dans le contexte d’une société en changement. Voilà une forme de la pratique théologique ou une autre modalité du service de la théologie que le professeur et doyen émérite René-Michel Roberge a accepté de remplir pendant une période importante de sa (...) vie, à la suite d’une carrière d’enseignant et de chercheur. En relisant cet itinéraire d’un professeur devenu administrateur de son institution de formation sans cesser d’être aussi un théologien, on trouve de bons indicateurs pour comprendre l’évolution du projet théologique dans une société en changement et pour être en mesure d’inscrire la parole théologienne dans l’espace public aujourd’hui. |: The purpose of this paper is to describe the challenges faced by one theologian who, as dean of a faculty of theology, steered a course designed to redefine the place that institution occupies within the Church, the university, and the changing society in which both were evolving. René-Michel Roberge, emeritus professor and dean, devoted a considerable part of his life to that form of practical theology required of anyone who would assume the leadership of a faculty of theology in a university setting ; and he took up this form of theological service on the heels of an already rich career as teacher and researcher. Revisiting the itinerary of this professor-cum-administrator of an institution of higher education, one finds indicators useful for situating the theological project and theological discourse in the public arena today.
