Let f be a computable function from finite sequences of 0ʼs and 1ʼs to real numbers. We prove that strong f-randomness implies strong f-randomness relative to a PA-degree. We also prove: if X is strongly f-random and Turing reducible to Y where Y is Martin-Löf random relative to Z, then X is strongly f-random relative to Z. In addition, we prove analogous propagation results for other notions of partial randomness, including non-K-triviality and autocomplexity. We prove that f-randomness relative to a (...) PA-degree implies strong f-randomness, hence f-randomness does not imply f-randomness relative to a PA-degree. (shrink)

Current efforts to think holistically about mental disorder may be assisted by considering the integrative strategies used by Hildegard of Bingen, a twelfth-century abbess and healer. We search for integrative strategies in the detailed records of Hilde-gard’s treatment of the noblewoman Sigewiza and in Hildegard’s more general writings. Three strategies support Hildegard’s holistic thinking: the use of narrative approaches to mental illness, acknowledging interdependence between perspectives, and applying principles of balance to the relationships between perspectives. Applying these three strategies to (...) the present-day conceptualization and treatment of mental disorder could move us toward a more thoroughly integrated understanding of the field. (shrink)

This commentary challenges the argument that the diathesis for hallucinations is equivalent to that for schizophrenia. Evidence against this comes from data on the prevalence of hallucinations in schizophrenia, their nonspecificity, and their relationships with moderating variables. We also highlight, however, the manner in which the Behrendt & Young (B&Y) hypothesis extends recent neuroscientific theories of schizophrenia, and its potential treatment applications.

Previous research indicates that individuals with depressive disorders have aberrant resting state functional connectivity and may experience memory dysfunction. While resting state functional connectivity may be affected by experiences preceding the resting state scan, little is known about this relationship in individuals with DD. Our study examined this question in the context of object memory. 52 individuals with DD and 45 healthy controls completed clinical interviews, and a memory encoding task followed by a forced-choice recognition test. A 5-min resting state (...) fMRI scan was administered immediately after the forced-choice task. Resting state networks were identified using group Independent Component Analysis across all participants. A network modeling analysis conducted on 22 networks using FSLNets examined the interaction effect of diagnostic status and memory accuracy on the between-network connectivity. We found that this interaction significantly affected the relationship between the network comprised of the medial prefrontal cortex, posterior cingulate cortex, and hippocampal formation and the network comprised of the inferior temporal, parietal, and prefrontal cortices. A stronger positive correlation between these two networks was observed in individuals with DD who showed higher memory accuracy, while a stronger negative correlation was observed in individuals with DD who showed lower memory accuracy prior to resting state. No such effect was observed for HC. The former network cross-correlated with the default mode network, and the latter cross-correlated with the dorsal attention network. Considering that the DMN and DAN typically anticorrelate, we hypothesize that our findings indicate aberrant reactivation and consolidation processes that occur after the task is completed. Such aberrant processes may lead to continuous “replay” of previously learned, but currently irrelevant, information and underlie rumination in depression. (shrink)

Niche construction refers to the activities of organisms that bring about changes in their environments, many of which are evolutionarily and ecologically consequential. Advocates of niche construction theory (NCT) believe that standard evolutionary theory fails to recognize the full importance of niche construction, and consequently propose a novel view of evolution, in which niche construction and its legacy over time (ecological inheritance) are described as evolutionary processes, equivalent in importance to natural selection. Here, we subject NCT to critical evaluation, in (...) the form of a collaboration between one prominent advocate of NCT, and a team of skeptics. We discuss whether niche construction is an evolutionary process, whether NCT obscures or clarifies how natural selection leads to organismal adaptation, and whether niche construction and natural selection are of equivalent explanatory importance. We also consider whether the literature that promotes NCT overstates the significance of niche construction, whether it is internally coherent, and whether it accurately portrays standard evolutionary theory. Our disagreements reflect a wider dispute within evolutionary theory over whether the neo-Darwinian synthesis is in need of reformulation, as well as different usages of some key terms (e.g., evolutionary process).

In lieu of an abstract, here is a brief excerpt of the content:Hildegard and HolismSuzanne M. Phillips (bio) and Monique D. Boivin (bio)Keywordsbiopsychosocial, integration, medieval, mental illnessWe appreciate the careful and enriching commentary offered by Kroll and by Radden on our paper about holistic views of mental illness in the writings of the twelfth-century abbess and healer Hildegard of Bingen. Both reviewers are well-established figures in the study of historical perspectives on mental illness, an area that we have just (...) begun to explore. We are glad for the opportunity to respond to their observations and thereby to continue the dialogue.First, we would like to clarify our purpose in preparing this paper. Nowhere do we claim that Hildegard used a biopsychosocial model of mental illness, either in addressing the needs of the particular case of Sigewiza, or more generally in her writings on illness and health. In fact, we agree with Kroll (2007, 370), when he states that Hildegard did not use a biopsychosocial model. We use the term “biopsychosocial” only three times in the paper, always by contrast with what we see in Hildegard’s writings. The present-day biopsychosocial model focuses on getting a range of perspectives on the table, encouraging the consideration of biological, psychological, and social issues when thinking about mental illness. This is a good thing, but we argue that it does not go far enough. Specifically, there has been insufficient attention to ways these perspectives might interact.How, then, might we describe Hildegard’s way of conceptualizing mental illness? In place of the label “biopsychosocial model,” Kroll suggests that Hildegard’s approach could be described as a “religious model” (p. 372). Here we disagree. By our reading, Hildegard’s description of mental illness involves religious components, certainly, but also humoral, astrological, interpersonal, community, and intrapsychic components. Radden correctly notes that we are not so much interested in the particular components as we are in their interactions. We are attracted to Hildegard’s writings because she attends to these interactions. Our students, like Kroll’s (p. 371), are curious about mind–body relationships, which represent one example of the interplay between components. Our concern is that the current biopsychosocial model often fails to satisfy our own, and our students’, interest in the nature of those interactions. Our hope is that Hildegard’s writings might help us to think more richly about the interactions.As Radden (2007, 373) points out, present-day psychiatrists and psychologists do in fact use mul-ticausal accounts of depression. And we agree that such accounts need not be reductionistic (Kroll, 371). But we also recognize that psychology and psychiatry have well-established reductionist (more specifically, materialist) habits. To borrow [End Page 377] Kroll’s phrase, the biological model threatens “to swallow all other models” (p. 371). We must guard against such reductionism, given the habits of our disciplines. As we noted, McHugh and Slavney (1998) respond to that threat by building walls between the perspectives, suggesting that we might use different perspectives when thinking about different sorts of problems. We think that there ought to be more synthetic, holistic ways of responding to that threat, and we are hopeful that Hildegard’s writings can help us to develop those.At a basic level, we see Hildegard asking different questions than people ask today. On the first page of his commentary, for example, Kroll poses the question of “which of these three modalities [bio-, psycho-, social] may be sufficient” (p. 369) in the particular medieval text. We found that the sufficiency of one modality or another does not concern Hildegard. We are not able to speak to the general point that Kroll raises, that one or another element is emphasized depending on the goal of the medieval text; we can report our experience in reading Hildegard, where we found no sense in which one or another component is privileged. Even though Hildegard operated within a thoroughly religious context, we did not find examples of her subsuming other factors under religion. Everything interacts with spiritual concerns, to be sure, but everything also interacts with the biological, and with the interpersonal, and with the astrological. Although it may seem odd to us post-Darwinian thinkers, Hildegard’s model is essentially... (shrink)

What determines whether an action is right or wrong? Morality, Rules, and Consequences: A Critical Reader explores for students and researchers the relationship between consequentialist theory and moral rules. Most of the chapters focus on rule consequentialism or on the distinction between act and rule versions of consequentialism. Contributors, among them the leading philosophers in the discipline, suggest ways of assessing whether rule consequentialism could be a satisfactory moral theory. These essays, all of which are previously unpublished, provide students in (...) moral philosophy with essential material and ask key questions on just what the criteria for an adequate moral theory might be.

This collection of essays on themes in the work of John Locke , George Berkeley , and David Hume , provides a deepened understanding of major issues raised in the Empiricist tradition. In exploring their shared belief in the experiential nature of mental constructs, The Empiricists illuminates the different methodologies of these great Enlightenment philosophers and introduces students to important metaphysical and epistemological issues including the theory of ideas, personal identity, and skepticism. It will be especially useful in courses devoted (...) to the history of modern philosophy. (shrink)

Update on donation of bodily material in the UKIn March 2010, the Human Tissue Authority announced that the first pooled kidney transplants, each involving three living donors and three recipients, had been performed in the UK. 1 While the vast majority of living donor transplants take place between people who are genetically related or are otherwise emotionally close, the Human Tissue Act 2004 introduced greater flexibility, permitting, for example, altruistic, paired and pooled donation. The HTA commented that these types of (...) donation represent one in three of all kidney transplants in the UK. Under the system of paired and pooled donation, in which someone needs a donor organ and has a friend or relative willing to donate, but the two are not compatible with each other, they can pair up with one or more other incompatible donor and recipient pairs in an organ exchange. In paired donation, donor A gives an organ to recipient B and donor B gives to recipient A; in pooled donation, more than two donor–recipient pairs take part in an organ exchange, coordinated by the HTA . Under the human tissue legislation, all cases of paired and pooled donation need to be considered by an independent assessor and approved by a panel of at least three members of the HTA, to ensure that all parties fully understand the risks involved and the donors are not under any pressure to donate.The first pooled transplant took place late in 2009, and was followed shortly afterwards by a second. Several paired living kidney transplants, involving two couples, had already taken place, however, with 16 such transplants going ahead between 1 April 2008 and 31 March 2009. Also in March 2010, a …. (shrink)

According to Roger Scruton, it is not possible for photographs to be representational art. Most responses to Scruton’s scepticism are versions of the claim that Scruton disregards the extent to which intentionality features in photography; but these cannot force him to give up his notion of the ideal photograph. My approach is to argue that Scruton has misconstrued the role of causation in his discussion of photography. I claim that although Scruton insists that the ideal photograph is defined by its (...) ‘merely causal’ provenance, in fact he fails to take the causal provenance of photographs seriously enough. To replace Scruton’s notion of the ideal photograph, I offer a substantive account of the causal provenance of photographs, centred on the distinctive role of ‘the photographic event’. I conclude that, with a proper understanding of the photographic process, we have good reason to re-open the question of photography as a representational art. (shrink)

When Ken Malone investigates a case of something causing mental static across the United States, he is teleported to a world that doesn't exist.

Open science has recently gained traction as establishment institutions have come on-side and thrown their weight behind the movement and initiatives aimed at creation of information commons. At the same time, the movement's traditional insistence on unrestricted dissemination and reuse of all information of scientific value has been challenged by the movement to strengthen protection of personal data. This article assesses tensions between open science and data protection, with a focus on the GDPR.

The collapse of confidence in anonymization as a robust approach for preserving the privacy of personal data has incited an outpouring of new approaches that aim to fill the resulting trifecta of technical, organizational, and regulatory privacy gaps left in its wake. In the latter category, and in large part due to the growth of Big Data–driven biomedical research, falls a growing chorus of calls for criminal and penal offences to sanction wrongful re-identification of “anonymized” data. This chorus cuts across (...) the fault lines of polarized privacy law scholarship that at times seems to advocate privacy protection at the expense of Big Data research or vice versa. Focusing on Big Data in the context of biomedicine, this article surveys the approaches that criminal or penal law might take toward wrongful re-identification of health data. It contextualizes the strategies within their respective legal regimes as well as in relation to emerging privacy debates focusing on personal data use and data linkage and assesses the relative merit of criminalization. We conclude that this approach suffers from several flaws and that alternative social and legal strategies to deter wrongful re-identification may be preferable. (shrink)

The study of word meanings promises important insights into the nature of the human mind by revealing what people find to be most cognitively significant in their experience. However, as we learn more about the semantics of various languages, we are faced with an interesting problem. Different languages seem to be telling us different stories about the mind. For example, important distinctions made in one language are not necessarily made in others. What are we to make of these cross-linguistic differences? (...) How do they arise? Are they created by purely linguistic processes operating over the course of language evolution? Or do they reflect fundamental differences in thought? In this sea of differences, are there any semantic universals? Which categories might be given by the genes, which by culture, and which by language? And what might the cross-linguistic similarities and differences contribute to our understanding of conceptual and linguistic development? The kinds of mapping principles, structures, and processes that link language and non-linguistic knowledge must accommodate not just one language but the rich diversity that has been uncovered. The integration of knowledge and methodologies necessary for real progress in answering these questions has happened only recently, as experimental approaches have been applied to the cross-linguistic study of word meaning. In Words and the Mind, Barbara Malt and Phillip Wolff present evidence from the leading researchers who are carrying out this empirical work on topics as diverse as spatial relations, events, emotion terms, motion events, objects, body-part terms, causation, color categories, and relational categories. By bringing them together, Malt and Wolff highlight some of the most exciting cross-linguistic and cross-cultural work on the language-thought interface, from a broad array of fields including linguistics, anthropology, cognitive and developmental psychology, and cognitive neuropsychology. Their results provide some answers to these questions and new perspectives on the issues surrounding them. (shrink)

We are told by philosophers that photographs are a distinct category of image because the photographic process is mind-independent. Furthermore, that the experience of viewing a photograph has a special status, justified by a viewer’s knowledge that the photographic process is mind-independent. Versions of these ideas are central to discussions of photography in both the philosophy of art and epistemology and have far-reaching implications for science, forensics and documentary journalism. Mind-independence (sometimes ‘belief independence’) is a term employed to highlight what (...) is important in the idea that photographs can be produced naturally, mechanically, accidentally or automatically. Insofar as the process is physical, natural, mechanical or causal it can occur without human agency or intervention, entirely in the absence of intentional states. Presented innocuously, the idea is that although photographs are dependent on natural or mechanical processes, they can be produced independently of human agency – particularly human beliefs. Presented in a stronger form, the claim is that even if human agency is heavily involved in the production process, the definitive features that make the photograph a photograph and determine its salient properties are nonetheless independent of human minds. In epistemic debates, mind-independence is viewed as essential for explaining why photographs occupy a distinct category among images and justifying a variety of claims about their privileged epistemic and affective status in science, forensics, popular culture and journalism. But, in the philosophy of art, claims about mind-. (shrink)

It is common to think that clarity is an essential ingredient of good teaching, meaning, in part, that good teachers always make it as easy as possible to follow what they say. We disagree. What we argue is that there are cases in which a philosophy teacher needs to forego clarity, making strategic use of obscurity in the undergraduate classroom.
