We prove that if p ≠ q are distinct primes, then the classification problems for p-local and q-local torsion-free abelian groups of rank two are incomparable with respect to Borel reducibility.

Greg Hjorth and Simon Thomas proved that the classification problem for torsion-free abelian groups of finite rank strictly increases in complexity with the rank. Subsequently, Thomas proved that the complexities of the classification problems for p-local torsion-free abelian groups of fixed rank n are pairwise incomparable as p varies. We prove that if 3≤m (...) that for q-local torsion-free abelian groups of rank n. (shrink)

This paper draws a parallel between two contemporary French conceptions of sociology. Each is first considered in terms of the principles and strategies of its sociological method. Through an analogy with Marx's philosophy of social science, critical sociology is shown to make an heuristic use for the analysis of cultures and social structures of the resistance to sociology that the sociologist encounters in the social objects, whereas pragmatic sociology adopts a pluralistic and descriptive strategy towards actions, actors and things. The (...) paper then tries to show how common interests or trading zones could allow both critical and pragmatic sociology to profit from their competitive relation by taking each other as objects of sociological analysis.

Forthcoming in Philosophy of Science. Despite some recent advances, multiple realization remains a largely misunderstood thesis. Consider the dispute between Lawrence Shapiro and Carl Gillett over the application of Shapiro’s recipe for deciding when we have genuine cases of multiple realization. I argue that Gillett follows many philosophers in mistakenly supposing that multiple realization is absolute and transitive. Both of these are problematic. They are tempting only when we extract the question of multiple realization from the explanatory context in which (...) it is invoked. Anchoring multiple realizability in its theoretical context provides grounds for arbitrating disagreements. Doing so, I argue, favors the view advanced by Shapiro. (shrink)

Re-analysis of the data provided in the target article reveals a lack of evidence for a strong, universal relationship between parasite stress and the variables relating to sociality. Furthermore, even if associations between these variables do exist, the analyses presented here do not provide evidence for Fincher & Thornhill's (F&T's) proposed causal mechanism.

The use of computers to support learning at work has for long been propagated. Although a large bulk of experience exists in this field, it is still an open question what role computer applications play and can play in the process of learning. It can even be questioned if the learning processes themselves are sufficiently well understood to enable designers and others to provide relevant support. In this article these questions are addressed with reference to experience gained with two projects (...) on computer support for shop floor learning. The projects involved the future users actively in the design process and it is argued that this involvement reached far beyond the mere shaping of the learning artefacts. (shrink)

The Association of American Medical Colleges (AAMC) is urging academic medical centers to ban pharmaceutical detailing. This policy followed from a consideration of behavioral and neuroeconomics research. I argue that this research did not warrant the conclusions drawn from it. Pharmaceutical detailing carries risks of cognitive error for physicians, as do other forms of information exchange. Physicians may overcome such risks; those determined to do so may ethically engage in pharmaceutical detailing. Whether or not they should do so is a (...) prudential judgment about which reasonable people may disagree. The AAMC's ethical condemnation of detailing is unwarranted and will subvert efforts to maintain a realm of physician discretion in clinical work that is increasingly threatened in our present practice environment.

In der neueren Erkenntnistheorie wird der Bayesianismus immer populärer. In diesem Ansatz werden Überzeugungen mit Glaubensgraden versehen. Dazu möchte ich der Frage nachgehen, ob wir den klassischen Ansatz in der Erkennnistheorie mit seinen kategorischen Überzeugungen komplett durch einen bayesianischen mit einem probabilistischen Überzeugungssystem ersetzen könnten. Um das zu klären, rekonstruiere ich zunächst beide Modelle unserer Überzeugungssysteme und vergleiche sie dann im Hinblick darauf, wie leistungsfähig sie jeweils dafür sind, erkenntnistheoretische Probleme zu lösen und als Grundlage für Entscheidungen zu dienen. Dabei (...) zeigt sich eine gewisse Inkommensurabilität der beiden Ansätze und außerdem erweist sich keine der Konzeptionen als eindeutig überlegen. Deshalb argumentiere ich schließlich für eine bestimmte Hybridkonzeption aus beiden Ansätzen, die die Vorteile beider Konzeptionen vereinen kann. (shrink)

While Wittgenstein’s work has been extensively investigated in relation to many other important and influential philosophers, there is very little scholarly work that positively investigates the relationship between the work of Wittgenstein and Wilhelm Dilthey. To the contrary, some commentators like Hacker (2001a) suggest that Dilthey’s work (and that of other hermeneuticists) simply pales or is obsolete in comparison to Wittgenstein’s own insights. Against such assessments, this article posits that Wittgenstein’s and Dilthey’s thought most crucially intersects at the related topics (...) of scientism on the one hand and scientific and philosophical method on the other. In reconstructing Dilthey’s conceptions of understanding versus explaining and central points of Wittgenstein’s Remarks on Frazer’s Golden Bough, it becomes apparent that they share a staunch rejection of scientism and use the notion of understanding as a means to prevent methodologies from the natural sciences encroaching onto the human sciences (in Dilthey’s case) and philosophy (in Wittgenstein’s case). Notwithstanding a number of central ways in which these thinkers differ, this article closes by suggesting that there is some evidence according to which Wittgenstein, like Dilthey, can reasonably be understood as championing some central tenets of the hermeneutical tradition.

This article investigates the claims and complexities involved in the platform-based economics of health and fitness apps. We examine a double-edged logic inscribed in these platforms, promising to offer personal solutions to medical problems while also contributing to the public good. On the one hand, online platforms serve as personalized data-driven services to their customers. On the other hand, they allegedly serve public interests, such as medical research or health education. In doing so, many apps employ a diffuse discourse, hinging (...) on terms like “sharing,” “open,” and “reuse” when they talk about data extraction and distribution. The analytical approach we adopt in this article is situated at the nexus of science and technology studies, political economy, and the sociology of health and illness. The analysis concentrates on two aspects: datafication and commodification. We apply these analytical categories to three specific platforms: 23andMe, PatientsLikeMe, and Parkinson mPower. The last section will connect these individual examples to the wider implications of health apps’ data flows, governance policies, and business models. Regulatory bodies commonly focus on the safety and security of apps, but pay scarce attention to health apps’ techno-economic governance. Who owns user-generated health data and who gets to benefit? We argue that it is important to reflect on the societal implications of health data markets. Governments have the duty to provide conceptual clarity in the grand narrative of transforming health care and health research. (shrink)

The President's Council on Bioethics has recently released a report supportive of the continued use of brain death as a criterion for human death. The Council's conclusions were based on a conception of life that stressed external work as the fundamental marker of organismic life. With respect to human life, it is spontaneous respiration in particular that indicates an ability to interact with the external environment, and so indicates the presence of life. Conversely, irreversible apnoea marks an inability to carry (...) out the necessary work of life, an inability which the Council considers an indicator of death. This conception has been conceived to circumvent criticisms of the previous model of loss of somatic integration, a model the Council admits that, in the presence of evidence of continuing functional integration in brain dead patients, was looking less than convincing. Nevertheless, by focusing on external work and ignoring the more essential work of integrative unity, the Council's conception of the nature of life is untenable, and of no assistance in supporting a relation of equivalence between the concepts of brain death and death. Consequently, the Council's conclusions do little to advance the definition of death debate, a potentially intractable debate that may necessitate the investigation of alternate ethical justifications for organ harvesting.

Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation between the affordances and constraints of project grants and the epistemic properties of research. However, the potentially very different affordances and constraints of funding arrangements (...) such as awards, prizes and fellowships, have not yet been taken into account. Drawing on eight case studies of funding arrangements in high performing Dutch research groups, this study compares the institutional affordances and constraints of prizes with those of project grants and their effects on organizational and epistemic properties of research. We argue that the prize case studies diverge from project-funded research in three ways: 1) a more flexible use, and adaptation of use, of funds during the research process compared to project grants; 2) investments in the larger organization which have effects beyond the research project itself; and 3), closely related, greater deviation from epistemic and organizational standards. The increasing dominance of project funding arrangements in Western science systems is therefore argued to be problematic in light of epistemic and organizational innovation. Funding arrangements that offer funding without scholars having to submit a project-proposal remain crucial to support researchers and research groups to deviate from epistemic and organizational standards.

The idea that it is acceptable to ‘nudge’ people to opt for the ‘healthy choice’ is gaining currency in health care policy circles. This article investigates whether researchers evaluating Abdominal Aortic Aneurysm Screening Programmes (AAASP) attempt to influence decision makers in ways that are similar to popular ‘nudging’ techniques. Comparing two papers on the health economics of AAASP both published in the BMJ within the last 3 years, it is shown that the values chosen for the health economics modelling are (...) not representative of the literature and consistently favour the conclusions of the articles. It is argued (1) that this and other features of these articles may be justified within a Libertarian Paternalist framework as ‘nudging’ like ways of influencing decision makers, but also (2) that these ways of influencing decision makers raise significant ethical issues in the context of democratic decision making.

Habit and habitualisation play an important role in Husserl's phenomenology, yet one aspect of habituality has been somewhat overlooked, namely the dimension of authenticity/inauthenticity. While authenticity in Heidegger has received a lot of attention, inauthenticity in Husserl is less well researched, although, as I will show, it is of equal importance to his overall theorising. The central aim of this paper is to explore the authenticity/inauthenticity-distinction in the various domains of habitualisation and to establish its fundamental importance for Husserl. In (...) the first, introductory part of this paper I offer a few remarks on how to understand and categorise Husserl's transcendental take on habits; I also introduce the important distinction between authentic and inauthentic habits and authenticity and inauthenticity in general. In the second part I present the problem of mechanisation as a form of inauthentic habitualisation as it appears in Husserl's phenomenologies of ethics and, more importantly, science. The third part concludes the paper with a reflection on how phenomenology is programmatically aimed against any form of inauthenticity, and on how it might or might not achieve this goal. (shrink)

One component of a viable account of scientific inquiry is a defensible conception of scientific problems. This paper specifies some logical and conceptual requirements that an acceptable account of scientific problems must meet as well as indicating some features that a study of scientific inquiry indicates scientific problems have. On the basis of these requirements and features, three standard empiricist models of problems are examined and found wanting. Finally a constraint inclusion-model of scientific problems is proposed.

In this article I argue that the intentional explanation of actions is a central task of the social sciences. However, the attribution of intentional states is highly underdetermined by observational data. Such attributions are forms of inference to the best explanation, and they have to cohere with our background knowledge of the conditions under which the agent acts. In addition to this ‚outer coherence’ we have to ask for an ‚inner coherence’ within the intentional profile of the agent to gain (...) a meaningful understanding. Both forms of coherence can help to reduce underdetermination. (shrink)

From the perspective of the present day, Puritan-inspired capitalism seems to have succeeded globally, including in India. Connected to this, short-term profit-orientation in management seems to constrain the scope of different management approaches in a tight ideological corset. This article discusses the possibility of replacing this Puritan doctrine with the crucial elements of Indian philosophy: Karma and samsara. In doing so, the possibility of revising the guiding principles in capitalist management becomes conceivable, namely the monetary focus of profit-orientation and its (...) short-term orientation. This perspective allows a detachment of the concept of profit from the realm of money, as the seemingly only objectifiable measure of profit. Furthermore it allows a removal of the expectation that every “investment” has to directly “pay off”. A karmic view offers management a possible facility for being more caring about the needs and fates of other stakeholders, as profit-orientation would no longer be attached as a factual constraint to merely accumulate money.

In this article, I explain and critique J. L. Schellenberg's atheological argument from horrors. I raise an epistemic objection, arguing that no one could be justified in believing its conclusion on the basis of its premises. Then I adumbrate a notion of the divine which is different in various ways from the God of classical theism and argue that Schellenberg's argument makes no trouble for belief in the existence of God so construed.

Current debates about sex selection start from a paradox: on the one hand, the 'liberal' argument in favour of sex selection is often thought to be sound; but on the other hand there is widespread public opposition to sex selection. So it is worth spending some time examining the arguments against sex selection. Four different types of argument are identified: (i) religious arguments; (ii) consequentialist arguments, mainly concerning disturbance to the sex ratio; (iii) arguments to the effect that sex selection (...) involves a failure to respect the autonomy of a child; (iv) arguments to the effect that the motivation for sex selection brings with it an instrumental attitude to children not compatible with a child's need for unconditional acceptance and love. In the end the conclusion is reached that none of these arguments provide decisive arguments against the liberal thesis that sex selection ought to be permitted, especially where 'family balancing' is envisaged. In the light of this conclusion the issue of fetal sexing followed by selective feticide as a method of sex selection C is discussed. It is argued that sex selection is not in general a good reason for abortion, but that this practice may become unstoppable. Copyright (C) 2006 John Wiley & Sons, Ltd. (shrink)
