The proof of the Second Incompleteness Theorem consists essentially of proving the uniqueness and explicit definability of the sentence asserting its own unprovability. This turns out to be a rather general phenomenon: Every instance of self-reference describable in the modal logic of the standard proof predicate obeys a similar uniqueness and explicit definability law. The efficient determination of the explicit definitions of formulae satisfying a given instance of self-reference reduces to a simple algebraic problem-that of solving the corresponding fixed-point equation (...) in the modal logic. We survey techniques for the efficient calculation of such fixed-points. (shrink)

In a recent paper, Montagna proved the undecidability of the first-order theory of diagonalisable algebras. This result is here refined — the set of finitely refutable sentences is shown effectively inseparable from the set of theorems. The proof is quite simple.

Background: Legislation on physician-assisted suicide is being considered in a number of states since the passage of the Oregon Death With Dignity Act in 1994. Opinion assessment surveys have historically assessed particular subsets of physicians.Objective: To determine variables predictive of physicians’ opinions on PAS in a rural state, Vermont, USA.Design: Cross-sectional mailing survey.Participants: 1052 physicians licensed by the state of Vermont.Results: Of the respondents, 38.2% believed PAS should be legalised, 16.0% believed it should be prohibited and 26.0% believed it should (...) not be legislated. 15.7% were undecided. Males were more likely than females to favour legalisation . Physicians who did not care for patients through the end of life were significantly more likely to favour legalisation of PAS than physicians who do care for patients with terminal illness . 30% of the respondents had experienced a request for assistance with suicide.Conclusions: Vermont physicians’ opinions on the legalisation of PAS is sharply polarised. Patient autonomy was a factor strongly associated with opinions in favour of legalisation, whereas the sanctity of the doctor–patient relationship was strongly associated with opinions in favour of not legislating PAS. Those in favour of making PAS illegal overwhelmingly cited moral and ethical beliefs as factors in their opinion. Although opinions on legalisation appear to be based on firmly held beliefs, approximately half of Vermont physicians who responded to the survey agree that there is a need for more education in palliative care and pain management.

This paper is an analysis of John Caputo’s philosophical interpretation of ‘the event’ as a form of revelation with specific reference to political theology and in dialogue with the theological notion of ‘interruption’ by the fundamental theologian Lieven Boeve. Following Charles Taylor’s interpretation of the post-secular, the argument is that Boeve’s ‘radical hermeneutics of religion’ is more postmodern than Caputo because it presents religion as co-constituted with language, particularity, and contingency and grounded within the specificity of the Christian narrative.

This study examines the presence and roles of female directors of U.S. Fortune 500 firms, focusing on committee assignments and director background. Prior work from almost two decades ago concludes that there is a systematic bias against females in assignment to top board committees. Examining a recent data set with a logistic regression model that controls for director and firm characteristics, director resource-dependence roles and interaction between director gender and director characteristics, we find that female directors are less likely than (...) male directors to sit on executive committees and more likely than male directors to sit on public affairs committees. There is little if any evidence of systematic gender bias in director assignment to other board committees. We find some evidence that boards evaluate resource dependence differently for women than men. (shrink)

According to appraisal theory, emotions result from an individual's meaning analysis of the implications of his/her circumstances for personal well-being, and individual differences in emotion arise when individuals appraise similar situations differently. Relational models of appraisal attempt to describe the situational and dispositional antecedents of appraisals, and should allow one to predict such individual differences. In this article, we review three examples of our efforts toward developing relational appraisal models. In two, we start with a particular appraisal component, motivational relevance (...) and problem-focused coping potential (Smith & Lazarus, 1990), respectively, and describe and test the relational model proposed for that component. In the third, as a precursor to developing a true relational model, we examine another appraisal component, emotion-focused coping potential, from a more dispositional perspective. We conclude by considering both the potential value of relational appraisal models, and future directions in the development of these models. (shrink)

Interpreters of Aquinas’s theory of natural law have occasionally argued that the theory has no need for God. Some, such as Anthony Lisska, wish to avoid an interpretation that construes the theory as an instance of theological definism. Instead Lisska sees Aquinas’s ontology of natural kinds as central to the theory. In his zeal to eliminate God from Aquinas’s theory of natural law, Lisska has overlooked two important features of the theory. First, Aquinas states that the desire for God is (...) a primary precept of the natural law and thus constitutes a critical aspect of his ontology. Secondly, Aquinas’s theory of natural law must be seen in the larger context of his theory of participation since he says, “The natural law is the rational creature’s participation in the eternal law.”.

Following the socialist revolution, a colossal shift in everyday realities began in the 1920s and '30s in the former Russian empire. Faced with the Siberian North, a vast territory considered culturally and technologically backward by the revolutionary government, the Soviets confidently undertook the project of reshaping the ordinary lives of the indigenous peoples in order to fold them into the Soviet state. In Agitating Images, Craig Campbell draws a rich and unsettling cultural portrait of the encounter between indigenous Siberians (...) and Russian communists and reveals how photographs from this period complicate our understanding of this history. Agitating Images provides a glimpse into the first moments of cultural engineering in remote areas of Soviet Siberia. The territories were perceived by outsiders to be on the margins of civilization, replete with shamanic rituals and inhabited by exiles, criminals, and "primitive" indigenous peoples. The Soviets hoped to permanently transform the mythologized landscape by establishing socialist utopian developments designed to incorporate minority cultures into the communist state. This book delves deep into photographic archives from these Soviet programs, but rather than using the photographs to complement an official history, Campbell presents them as anti-illustrations, or intrusions, that confound simple narratives of Soviet bureaucracy and power. Meant to agitate, these images offer critiques that cannot be explained in text alone and, in turn, put into question the nature of photographs as historical artifacts. An innovative approach to challenging historical interpretation, Agitating Images demonstrates how photographs go against accepted premises of Soviet Siberia. All photographs, Campbell argues, communicate in unique ways that present new and even contrary possibilities to the text they illustrate. Ultimately, Agitating Images dissects our very understanding of the production of historical knowledge. (shrink)

In his landmark monograph, "The Politics of Jesus", John Howard Yoder challenged mainstream Christian social ethics by arguing that the New Testament account of Jesus's founding of a messianic community entails a normative politics, not only for early Christianity but for the contemporary church. This challenge is further elaborated in several important posthumous publications, especially "Preface to Theology", in which Yoder examines the development of early Christology with attention to its political and ethical implications, and "The Jewish-Christian Schism Revisited", Yoder's (...) proposal for a renewed Jewish-Christian dialogue around the moral meaning of messianism. This article interprets these writings with reference to a range of critical scholarship on and about Yoder, Yoder and Augustine, and Jewish and Christian messianism, paying particular attention to questions of political ethics.

The present study examined a relational model of appraisal that specifies the situational and dispositional antecedents of appraised problem-focused coping potential, itself a hypothesised antecedent of the emotions of hope/challenge and resignation. The hypothesised relational antecedents of this appraisal were tested in a quasi-experiment in which individuals varying in self-perceived and objectively assessed math ability attempted to solve math problems on which difficulty was manipulated. Findings for the critical test problem largely conformed to predictions: Under difficult conditions, but not easy (...) ones, increasing math ability was generally associated with elevated appraisals of problem-focused coping potential, increased hope/challenge, reduced resignation, and increased likelihood of solving the problem. However, problem-focused coping potential, hope/challenge, and the likelihood of solving the problem were all lower, and resignation was higher, for the highest ability participants, than would be predicted from their ability levels. Comparable findings were not observed for appraisals of emotion-focused coping potential or its theoretically associated emotion of anxiety, providing evidence of discriminant validity for the examined model. The results of a mediational analysis supported the hypothesis that the effects of the quasi-experimental design on hope/challenge and resignation were mediated by their effects on appraised problem-focused coping potential, lending support to the proposition that appraisals play a causal role in emotion elicitation.

It has long been a commonly held belief among classicists that traditional Romans frowned upon male homosexuality and associated it with the influence of Greek culture. There have always been exceptions to this belief, but when Paul Veyne published the following remarks in his 1978 article ‘La famille et l'amour sous le hautempire romain’, his views were quite heterodox: Il est faux que l'amour ‘grec’ soit, à Rome, d'origine grecque: comme plus d'une société méditerranéenne de nos jours encore, Rome n'a (...) jamais opposé l'amour des femmes à celui des garçons: elle a opposé l'activité à la passivité; être actif, c'est être un mâle, quel que soit le sexe du partenaire passif.

The Internet is rapidly developing into an important medium of communication in modem society, and both psychological research and therapeutic interventions are being increasingly conducted using this new communication medium. As therapeutic interventions using the Internet are becoming more prevalent, it is becoming increasingly important to conduct research on psychotherapeutic Internet interventions to assist in the development of an appropriate standard of practice regarding interventions using this new medium. In this article, we examine the Internet and the current psychological uses (...) which are being initiated using this medium. Ethical concerns related to the psychological use of the Internet are discussed, and guidelines are proposed for the conduct of Internet intervention research. (shrink)

This article examines the anonymous progymnasmata in John Doxapatres' commentary on Aphthonius' Progymnasmata for evidence about their authorship, origin, and relations to other progymnasmata. These exercises include three chreias, a refutation and confirmation of the myth of Ganymedes, an encomium and invective of Agamemnon, a comparison of the grapevine and olive tree, and an ethopoeia on the deposition of the emperor Michael V Kalaphates. In addition to providing a formal rhetorical analysis of the exercises, the article offers further support for (...) the view of R. F. Hock and E. N. O'Neil that Doxapatres did not compose these exercises and that they all derive from a single collection. In an appendix, it argues that George Pachymeres, in his comparison of the olive tree and grapevine, used the anonymous comparison in Doxapatres and not the four parallel exercises by Ps.-Nicolaus.

In her book The Myth of Sacred Prostitution in Antiquity, Stephanie Budin compiles and analyses an impressive array of literary sources which describe, or have been interpreted as describing, several practices that modern scholars have collectively and variously called sacred, ritual, cultic or temple prostitution. In general, as Budin explains, ‘[s]acred prostitution is the sale of a person's body for sexual purposes where some portion of the money or goods received for this transaction belongs to a deity … usually Aphrodite’. (...) Three major subtypes include ‘once-in-a-lifetime prostitution and/or sale of virginity in honor of a goddess’, activity that ‘involves women who are professional prostitutes and who are owned by a deity or a deity's sanctuary’, and ‘a temporary type of sacred prostitution, where the women are either prostitutes for a limited period of time before being married, or only prostitute themselves during certain rituals’.
