Bizarre delusions are not specific to schizophrenia and can be found in other psychotic disorders. However, to date, there are no studies investigating socio-demographic and clinical characteristics associated with BizD across the psychosis spectrum. In this study 819 subjects with a diagnosis of SZ, schizoaffective disorder and bipolar I disorder were included. Patients with history of BizD and with no BizD were compared with respect to socidemographic and clinical variables, and predictors of BizD were explored. Patients with BizD were less (...) educated, less likely to be married, had higher Positive and Negative Syndrome Scale negative scores and lower Young Mania Rating Scale scores. Younger age, SZ and SZA diagnoses, higher PANSS positive scores, presence of reference delusions, tactile and olfactory hallucinations were predictors. Our results indicate that BizD are associated with higher illness severity, lower functionality and specific set of symptoms. (shrink)

This book traces the intellectual revolution initiated by Thales in the sixth century BC to its culmination in the metaphysics of Parmenides.

Changes in healthcare financing increasingly rely upon patient cost-sharing to control escalating healthcare expenditures. These changes raise new challenges for physicians that are different from those that arose either under managed care or traditional indemnity insurance. Historically, there have been two distinct bases for arguing that physicians should not consider costs in their clinical decisions—an “aspirational ethic” that exhorts physicians to treat all patients the same regardless of their ability to pay, and an “agency ethic” that calls on physicians to (...) be trustworthy advisors to their patients. In the setting of greater patient cost-sharing, physicians' aspiration and agency roles increasingly conflict. Satisfactorily navigating the new terrain of consumer-driven healthcare requires physicians to consider these two roles and how they can best be reconciled so as to maximize quality of care while respecting the heterogeneity of patients' financial resources and willingness to pay.

This book, published in 1986, addresses questions concerned with a central normative principle in contemporary assessments of economic policies and systems. What does 'consumer sovereignty' mean? Is consumer sovereignty an appropriate principle for the optimization and evaluation of the design and performance of economic policies, institutions and systems? If not, what is a more appropriate principle? The author argues that the conception of consumer sovereignty has to be broadened so that it is not limited to the market mechanism but includes (...) environmental, work and social preferences. However, even this version runs into serious difficulties as the principle of consumer sovereignty still relies on too subjectivist a conception of the interests of individuals to be suitable for the evaluation of economic institutions. An alternative basis for such evaluation is 'human interests' that are not contingent on particular economic systems, After considering various possibilities, a basic-needs approach is proposed and its use in economic evaluation illustrated.

Zermelo once wrote that he had anticipated Russell's contradiction of the set of all sets that are not members of themselves. Is this sufficient for having anticipated Russell's Paradox — the paradox that revealed the untenability of the logical notion of a set as an extension? This paper argues that it is not sufficient and offers criteria that are necessary and sufficient for having discovered Russell's Paradox. It is shown that there is ample evidence that Russell satisfied the criteria and (...) that Zermelo did not. (shrink)

After briefly reviewing the standard set-theoretic resolutions of the Burali-Forti paradox, we examine how the paradox arises in set theory formalized with plural quantifiers. A significant choice emerges between the desirable unrestricted availability of ordinals to represent well-orderings and the sensibility of attempting to refer to ‘absolutely all ordinals’ or ‘absolutely all well-orderings’. This choice is obscured by standard set theories, which rely on type distinctions which are obliterated in the setting with plurals. Zermelo's attempt ( 1930 ) to secure (...) ordinal representability of arbitrary well-orderings through relativization of quantification to set-theoretic models is reviewed and found wanting. The natural modal-structural recasting provides, it is claimed, a good repair. (shrink)

This article focuses mainly on (1) the policy of Delft University of Technology since 1992 as regards the university-wide introduction of a compulsory course on ethics and engineering, and (2) the ideal structure of such a course, including the educational goals of the course.

Ludwig Wittgenstein was born in 1889, son of parents of Jewish extraction but not Jewish religion. Asked how his family came by the name ‘Wittgenstein’ Ludwig said they had been court Jews to the princely family and so had taken the name when Jews were required by law to have European-style names. The father, Karl, was a Protestant, the mother a Catholic. The Jewish blood was sufficient to bring the family later on into danger under Hitler's Nuremberg Laws. They did (...) not think of themselves as Jews or belong to the Jewish community in Vienna. The children were brought up sort-of Catholic though so far as I know only the eldest, Hermine, towards the end of her life, took this seriously and made a profession of faith before friends and household. At 9 years of age Ludwig and Paul, a year or two older than Ludwig, talked together and decided that their religion was all nonsense. Paul became a pianist of some fame, but soon after his debut in Vienna he became a wounded prisoner on the Russian front and his arm was lopped off by a surgeon who did not know he was a pianist.

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

The randomization ingredient in double-blind controlled experiments may be objectionable to patients who, in their desperation, come to such trials seeking a last chance of cure. Minogue et al., who view such a situation as inherently exploitive and undermining of patient autonomy, propose that such “desperate volunteers” instead be enrolled in the active arm, while other patients, less desperate and more committed to medical progress, continue to be randomized. Their view is critiqued as destructive of medical progress, inappropriate in its (...) lack of clinical response to such patients, and fatally flawed by unrealistic notions of autonomy and voluntariness.

This paper examines the identity of Asian swamp buffalo (Bubalus bubalis) from different value orientations. Buffalo were introduced into Northern (Top End) Australia in the early nineteenth century. A team of transdisciplinary researchers, including an ethicist, has been engaged in field research on feral buffalo in Arnhem Land over the past three years. Using historical documents, literature review, field observations, interviews with key informants, and interaction with the Indigenous land owners, an understanding of the diverse views on the scientific, cultural, (...) and economic significance of buffalo was obtained. While the diverse stakeholders in buffalo exploitation and management have historically delivered divergent value orientations on the nature of the human–buffalo relationship, we argue that over time there is the possibility of values and ethical convergence. Such convergence is possible via transdisciplinary and transcultural agreement on the value stances that constitute the construction of the being or identity of buffalo in the face of the overwhelming need to manage population density and gross numbers.
