There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

Semantic Indexicality shows how a simple syntax can be combined with a propositional language at the level of logical analysis. It is the adoption of such a base language which has not been attempted before, and it is this which constitutes the originality of the book. Cresswell's simple and direct style makes this book accessible to a wider audience than the somewhat specialized subject matter might initially suggest.

We consider the desirability, or otherwise, of various forms of induction in the light of certain principles and inductive methods within predicate uncertain reasoning. Our general conclusion is that there remain conflicts within the area whose resolution will require a deeper understanding of the fundamental relationship between individuals and properties.

An emerging ethical philosophy in marketing is developing. This philosophy is based on quality-of-life studies which are becoming an important topic of research in behavioral and social sciences (basic and applied research). This paper addresses the QOL orientation in marketing from a decision-making perspective. Specifically, this paper shows how marketers can engage in strategic marketing planning guided by the QOL concept.

Television medical dramas sometimes depict medical professionalism and bioethical issues, but their nature and extent are unclear. The authors systematically analysed the bioethical and professionalism content of one season each of Grey's Anatomy and House M.D., two of the most popular current television medical dramas. The results indicate that these programmes are rife with powerful portrayals of bioethical issues and egregious deviations from the norms of professionalism and contain exemplary depictions of professionalism to a much lesser degree.

Under the assumption that all "rules" are recursive (ECT) the statement $\operatorname{Cont}(N^N,N)$ that all functions from N N to N are continuous becomes equivalent to a statement KLS in the language of arithmetic about "effective operations". Our main result is that KLS is underivable in intuitionistic Zermelo-Fraenkel set theory + ECT. Similar results apply for functions from R to R and from 2 N to N. Such results were known for weaker theories, e.g. HA and HAS. We extend not only (...) the theorem but the method, fp-realizability, to intuitionistic ZF. (shrink)

Implicit God-like and ghost-in-the-machine metaphors underlie much current thinking about genomes. Although many criticisms of such views exist, none have succeeded in substituting a different, widely accepted view. Viewing the genome with its protein packaging as a brain gets rid of Gods and ghosts while plausibly integrating machine and information-based views. While the ‘wetware’ of brains and genomes are very different, many fundamental principles of how they function are similar. Eukaryotic cells are compound entities in which case the nuclear genome (...) might best be thought of more as a government than simply as a brain. (shrink)

In this paper we first give a survey of reductive cut-elimination methods in classical logic. In particular we describe the methods of Gentzen and Schütte-Tait from the abstract point of view of proof reduction. We also present the method CERES which we classify as a semi-semantic method. In a further section we describe the so-called semantic methods. In the second part of the paper we carry the proof analysis further by generalizing the CERES method to CERESD . In the generalized (...) version CERESD we admit general elimination rules which are based on the mere semantical truth of sentences. We construct complete cut-free LK-derivations originating from derivations potentially containing unproven lemmas. Finally we give a comparison of reductive methods and CERESD by presenting a general simulation result. (shrink)

Jacob (history, New School for Social Research) proposes that the science of the 17th and 18th centuries was eventually accepted because it was made compatible with larger political and economic interests. A celebration of the recently concluded 33 volume edition of the Collected works of John Stuart Mill, produced over a period of nearly 30 years, the last 20 under the guiding genius (and hand) of general editor Robson. Following a tributary history of the project itself, essays cover Mill's career (...) as a thinker and as a bureaucrat and public servant, exploring the effects of the various milieu--domestic, political, administrative, religious, and cultural--in which he moved.

The purpose of this essay is to argue for the necessity of an ethics of the practice of the specialist-technologist in medicine. In the first part I sketch three stages of medical ethics, each with a particular viewpoint regarding the technology of medicine. I focus on Brody's consideration of the physician's power as a example of contemporary medical ethics which explicitly excludes the specialist-technologist as a locus of development of medical ethics. Next, the philosophy of Heidegger is examined to suggest (...) an approach to the problem, and, finally, some of Levinas' contributions regarding the other are introduced to suggest a preliminary approach to a medical ethics of the specialist-technologist.

Poor pregnancy outcomes and inequalities in these outcomes remain a major challenge, even in prosperous societies that have high-quality health care and public health policy in place. In this article, we propose that justice demands the improvement of what we call the ‘health agency’ of parents-to-be as part of a response to these poor outcomes. We take health agency to have three aspects: the capacity to form health-goals one has reason to value, the control one perceives to have over achieving (...) those health-goals and the freedom one has to achieve those health-goals. We will moreover argue that this demand of justice can be best based on a perfectionist rather than neutralist method of justification. Subsequently, we will argue that perfectionist policy may be paternalistic but not wrongfully paternalistic. This leads us to conclude that perfectionism should be adopted to inform and justify public health policy that is aimed at improving health agency in general and counteracting poor pregnancy outcomes and inequalities in perinatal health outcomes in particular.

Since 1994, when the first fetal imaging boutique appeared in Texas, many sites have been established around the country for parents to receive nonmedical fetal imaging using three- and four-dimensional ultrasound machines. These businesses boast the benefits they offer to parental-fetal bonding, but the medical community objects to the use of ultrasound machines for nonmedical purposes. In this article, I present the statements released by the medical community, highlighting the alarmist strategies used to paint boutique ultrasounds as bad science and (...) elevate the medical use of ultrasounds. Through a close reading of the statements, it is shown that the medical community's primary concern is not the health of the fetus or the woman but rather their place as the sole users of fetal ultrasounds. This detailed analysis reveals a medical community fearful that its authority is being usurped and is therefore responding with statements meant to denigrate boutique fetal ultrasounds. (shrink)

Charting the development of the British tradition of naturalism from the 17th to the 19th century, this book provides fascinating insight into a wide range of thinkers, both Catholic and Protestant, who explored the themes of proof, practice, and the role of common sense. Reappraising what these thinkers can teach us about the relations between belief, action, and skepticism, Ferreira contributes to the philosophical study of naturalist replies to skepticism, as well as to a deeper appreciation of this particular segment (...) of British intellectual history.

One of the most tantalizing questions about the interpretation of Quantum Theory is the objective vs. subjective meaning of quantum states. Here, by focusing on a typical EPR experiment upon which a selection procedure is performed on one side, we will confront the fully epistemic view of quantum states with its results. Our statement is that such a view cannot be considered complete, although the opposite attitude would also pose well-known problems of interpretation.

In this paper we will show that Hempel's covering law model can't deal very well with explanations that are based on incomplete knowledge. In particular the symmetry thesis, which is an important aspect of the covering law model, turns out to be problematic for these explanations. We will discuss an example of an electric circuit, which clearly indicates that the symmetry of explanation and prediction does not always hold. It will be argued that an alternative logic for causal explanation is (...) needed. And we will investigate to what extent non-monotonic epistemic logic can provide such an alternative logical framework. Finally we will show that our non-monotonic logical analysis of explanation is not only suitable for simple cases such as the electric circuit, but that it also sheds new light on more controversial causal explanations such as Milton Friedman's explanation of the business cycle.

This paper gives a simple, elegant statement of the condensed detachment rule that is independent of most general unifiers and proves that this is equivalent to the longer, more usual, formulation.

Science education is most efficacious and enduring when undertaken within a philosophical framework akin to that of science, itself. This entails recognition that, above all, science is a mode of rational inquiry pursued by those who are curious about the natural world and motivated to seek rational answers to personally meaningful questions. The key to successful science instruction lies in fostering a student' 's self-motivation and productively channeling his innate curiosity. To do this a science educator must convey to students (...) an accurate and sympathetic impression of the importance of science to their cultural development; help students develop an ability to evaluate information critically and arrive at logical conclusions; provide students opportunities to engage in creative, personally meaningful scientific research.
