Representation of subjective preferences under ambiguity

The objective of this paper is to show how potentially incomplete preferences of a decision maker (DM) on acts can be modelled formally in a subjective ambiguity perspective. We identify acts as functions from a state space Ω to bounded support (finitely additive) probabilities over a set X of prizes. Then, we characterize preferences over equibounded acts a which have a numerical representation by the family of functionals , where u is a cardinal utility on X (representing the risk attitude of the DM) and Π is a unique pointwise closed convex set of probabilities on all events in Ω (representing the ambiguity perceived by the DM). To this end, in addition to the usual independence and continuity assumptions, we add completeness and dominance for preferences restricted to constant acts; moreover, we consider two other properties (subjective monotonicity and coherence) related with the preferences of a DM who is not able, owing to his partial knowledge, to evaluate any event in Ω.     

Morality and the View from Here

According to one influential conception of morality, being moral is a matter of acting from or in accordance with a moral point of view, a point of view which is arrived at by abstracting from a more natural, pre-ethical, personal point of view, and recognizing that each person's personal point of view has equal standing. The idea that, were it not for morality, rational persons would act from their respectively personal points of view is, however, simplistic and misleading. Because our nonmoral reasons cannot all be adequately captured as falling within any single, unified and coherent point of view, morality cannot be adequately understood as a matter of abstracting from such points of view and taking them all equally into account. After considering several ways of modifying the initial conception of morality in a way that accommodates the variety of nonmoral reasons that do not have their source in a personal point of view, the paper concludes with the suggestion that we free ourselves more thoroughly from the grip of the metaphor that takes morality as a whole to be a matter of acting in accordance with the judgments of a single unified and coherent point of view.

近年来,临床中关于反复胸闷胸痛患者的较高误诊率引起了广大医务工作者的重视,此类患者伴有的心理精神障碍往往被忽视,得不到合理的治疗,预后较差.本文主要讨论关于反复胸闷胸痛患者病因的鉴别、心理精神障碍引起胸闷胸痛的机制、胸闷胸痛与心理精神障碍的关系、“双心”医学诊疗模式以及反复胸闷胸痛的治疗进展,通过增强临床医生对“双心”医学的认识降低胸闷胸痛患者的误诊率、漏诊率,减少过度治疗,通过心血管医学和心理干预联合治疗,改善心血管疾病患者的预后、降低死亡率.     

THE CRAZINESS FOR EXTRA‐SENSORY PERCEPTION: QIGONG FEVER AND THE SCIENCE–PSEUDOSCIENCE DEBATE IN CHINA

From 1979 to 1999, a heated dispute over the science or pseudoscience of extraordinary power or extrasensory perception (ESP) took place in China. During these two decades, many so‐called “grandmasters” of ESP and Qigong emerged, and millions of people across the country studied with them; this was known as “Qigong Fever” or “ESP Fever.” The supporters of ESP argued that ESP existed, people could cultivate ESP through specific Qigong training, and ESP was a science; whereas the opponents of ESP denied all of these. Both sides of the dispute had many supporters. With the onset of Qigong Fever in China, some Qigong and ESP masters developed their Qigong organizations into Chinese‐style religions. Qigong Fever ended when the religions were banned by the Chinese government. The rise of Qigong Fever demonstrated that basic questions about the boundaries between science and pseudoscience were not easy to answer. Different theoretical and practical consequences resulted from different answers to these questions.     

J. S. Mill on Coolie Labour and Voluntary Slavery

This article discusses John Stuart Mill's voluntary slavery argument in On Liberty. The author shows that standard interpretations of the argument rely on the assumption that part of Mill's objection to voluntary slavery is the permanent nature of the decision. However, in correspondence, Mill also objects to voluntary ‘coolie’ labour contracts, which he regards as a form of slavery. This produces difficulties for standard interpretations of the voluntary slavery argument. Finally, the author provides a revised interpretation of Mill's argument to solve this problem.     

Digit ratios,but not facial width-to-height ratios,are associated with the priority placed on attending to faces versus bodies

Testosterone has been linked to a sexual preference for bodies rather than faces. Low digit ratio (2D:4D) and high facial width-to-height ratio (WHR) are associated with high prenatal testosterone. We tested whether low 2D:4D and high facial WHR were correlated with a preference for bodies over faces. Our sample consisted of 109 college students (64 males). A two-way analysis of variance demonstrated a significant main effect of digit ratio on the priority placed on paying attention to faces or bodies such that low 2D:4D was linked to a preference for bodies, but the effect of sex was not significant. There were no significant interaction effects. Another two-way analysis of variance revealed no significant effects for facial WHR and attentional priority but significant associations between sex and attentional priority. There were no significant interaction effects. Our findings indicate that individuals with low digit ratios tended to pay more attention to bodies than to faces compared with individuals with higher digit ratios, independently of sex. We also found that males tended to pay more attention to bodies than to faces compared with females, independently of facial WHR.     

Discourse theory trumps discourse theory: Wouter Hanegraaff's Esotericism and the Academy

This review article argues that Wouter Hanegraaff's Esotericism and the Academy is deeply influenced by a methodological cluster usually referred to as ‘discourse theory.’ That the author is not willing to classify his own approach as such is explained with recourse to his dispute with Kocku von Stuckrad, who, according to Hanegraaff, would embody discourse theory, whereas Hanegraaff would embody history. A comparison of Hanegraaff's Esotericism and the Academy: Rejected Knowledge in Western Culture (Cambridge: Cambridge University Press, 2012) and von Stuckrad's Locations of Knowledge in Medieval and Early Modern Europe: Esoteric Discourse and Western Identities (Leiden: Brill, 2010) reveals that this is a misleading classification and that Hanegraaff's study comes closer to what discourse theory is all about. As a consequence, Esotericism and the Academy is the very first study on ‘Western esotericism’ that offers a convincing justification of this particular label as an overarching discursive category.     

Perceptions of alcohol risk among people on antiretroviral treatment in South Africa: a qualitative study

This study explored perceptions of alcohol abuse risk among people on antiretroviral treatment (ART) who self-identified as alcohol users. Twenty six people receiving ART from an out-patient setting were interviewed on their alcohol abuse risk perception. Data were thematically analysed. Findings suggest participants developed routines to drink alcohol around the times they took their antiretroviral medications to reduce adverse impact. They also reported alcohol abuse risk reduction strategies such as reducing alcohol use because of the event of an HIV positive diagnosis and/or getting on antiretroviral treatment, and alcohol use reduction following health education or counselling by health care staff. These findings suggest a need for alcohol interventions tailored to ART patients.     

Gender: Genetics,Genitality, Generosity (Grace), Gentility

After acknowledging that gender is defined at many levels and that definitions may not be concordant across all of these layers of human development, this essay illuminates how these threads intertwine with one another to produce a final product that we call a person. Gene expression, gender identity, sexual orientation, and anatomic structures are not always coterminus. Arbitrarily assigning an infant child with maldefined genitalia to a socially defined gender role on the basis of surgical convenience may (should) be perceived as an act of violence, and an untruth. A further intent of this article is to help in pastoral settings to respond to events which raise points of anxiety and concern, among persons of faith, which are sometimes associated with instances of discrepancy.
