Joint actions often require agents to track others’ actions while planning and executing physically incongruent actions of their own. Previous research has indicated that this can lead to visuomotor interference effects when it occurs outside of joint action. How is this avoided or overcome in joint actions? We hypothesized that when joint action partners represent their actions as interrelated components of a plan to bring about a joint action goal, each partner’s movements need not be represented in relation to distinct, (...) incongruent proximal goals. Instead they can be represented in relation to a single proximal goal – especially if the movements are, or appear to be, mechanically linked to a more distal joint action goal. To test this, we implemented a paradigm in which participants produced finger movements that were either congruent or incongruent with those of a virtual partner, and either with or without a joint action goal (the joint flipping of a switch, which turned on two light bulbs). Our findings provide partial support for the hypothesis that visuomotor interference effects can be reduced when two physically incongruent actions are represented as mechanically interdependent contributions to a joint action goal.

Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

The field of neuroimaging has reached a watershed. Brain imaging research has been the source of many advances in cognitive neuroscience and cognitive science over the last decade, but recent critiques and emerging trends are raising foundational issues of methodology, measurement, and theory. Indeed, concerns over interpretation of brain maps have created serious controversies in social neuroscience, and, more important, point to a larger set of issues that lie at the heart of the entire brain mapping enterprise. In this volume, (...) leading scholars -- neuroimagers and philosophers of mind -- reexamine these central issues and explore current controversies that have arisen in cognitive science, cognitive neuroscience, computer science, and signal processing. The contributors address both statistical and dynamical analysis and modeling of neuroimaging data and interpretation, discussing localization, modularity, and neuroimagers' tacit assumptions about how these two phenomena are related; controversies over correlation of fMRI data and social attributions ; and the standard inferential design approach in neuroimaging. Finally, the contributors take a more philosophical perspective, considering the nature of measurement in brain imaging, and offer a framework for novel neuroimaging data structures.

I agree fully that a “clearer picture of how vulnerability might manifest and how it can be accommodated, ideally without resorting to mere exclusion from research, is needed” (Friesen et al. 2023,...

This article argues that teaching medical and nursing students health care ethics in an interdisciplinary setting is beneficial for them. Doing so produces an education that is theoretically more consistent with the goals of health care ethics, can help to reduce moral stress and burnout, and can improve patient care. Based on a literature review, theoretical arguments and individual observation, this article will show that the benefits of interdisciplinary education, specifically in ethics, outweigh the difficulties many schools may have in (...) developing such courses.

: In Engelhardt's secular bioethics, moral obligations derive from contracts and agreements between rational persons, and no infants or children and few adolescents meet Engelhardt's requirements for being a rational person. This is a problem, as one cannot have any direct secular moral obligations toward nonpersons such as infants and adolescents. The Engelhardtian concepts of ownership, indenture, and social personhood, which are meant to allow the theory to accommodate children and adolescents adequately, fail to give an Engelhardtian any actual means (...) of determining the right action to take in difficult cases, even on his or her own terms. Thus, the theory is incapable of determining the morally correct action to take in cases involving children and therefore is unhelpful in dealing with moral questions involving children. (shrink)

ABSTRACTTeam physicians have a complicated job that involves potentially conflicting obligations to multiple entities. Though responsible for the medical care of the athletes as individuals, they also have obligations to the team that employs them which can include returning athletes to play who are at heightened risk of re-injury. The fact that the athletes and owners have some overlapping interests only complicates this issue. Further, there are strong financial incentives to do what is necessary to obtain and keep a position (...) as a team physician. This article examines dual loyalty and conflict of interest in sports medicine, and argues that there is not now a widely accepted or adequate solution to either. Moving toward a solution will require fairly serious changes in the role of the team physician.Abbreviations: FIMS International Federation of Sports Medicine; NFL National Football League; MVP Most Valuable Player; RGIII Robert Griffin, III.

The development of a code of ethics for a profession can be an indicator of the coherence and stability of a discipline as a unique and singular entity. Since “bioethics”, as a discipline, is not one profession but many, practiced by persons with not one but many varying responsibilities and training, it has been argued that no code of ethics is possible for the discipline(s) of bioethics. I argue that a code of ethics is possible for bioethics by looking at (...) the nature of the various disciplines and noting necessary overlap between them, and deriving the ethics from the nature of the discipline(s) themselves. I show how this can be done by arguing that strict rules about funding and conflict of interest are necessary for bioethicists. (shrink)

Makins’s analysis of the philosophical justification of decision-making understates and so misinterprets the importance of patient values to ‘the deference principle.’ (Makins N,1, p1) He assesses autonomy and beneficence as two separate arguments in support of deferring to patient preferences, but they only work well considered together. Further, neither the constitutive nor the evidential view of beneficence fully recognises the importance of patient values to understanding the patient’s worldview, which in turn determines what risks and benefits matter most. Revising these (...) arguments enables a much fuller understanding of the importance of patient values to the practice of medicine, which will in turn improve the refinement of the deference principle. Autonomy requires beneficence, and vice versa, for either of them to be sufficient arguments for deferring to patient choices. Focusing on autonomy alone to justify deference overstates the value of choice in and of itself, as good medicine does not pursue just any choices. It seeks informed consent, which means that the choices we truly value are those made while understanding what is importantly relevant to the choice. A well-informed decision includes data about expected side effects and likelihood of beneficial effects; but it also includes knowing the patient’s values and goals. One must know what is actually valuable …. (shrink)

Jotkowitz, Glick, and Gesundheit (2008) rightly critique Manninen (2006) for an errant analysis of the Groningen protocol. However, they draw conclusions about the protocol itself that are not justified. Because of the nature of the care of infants, the Groningen protocol doesn't break new ethical ground. We already have to treat infants without direct access to their autonomous preferences or values; therefore, we are already making the decisions that Jotkowitz, Glick, and Gesundheit argue we are beginning to take once active (...) euthanasia of infants is allowed.

Rationale Treatment guidelines recommend a more conservative surgical approach than mastectomy for early stage breast cancer and a stronger emphasis on adjuvant therapy. Registry data at South Australian teaching hospitals have been used to monitor survivals and treatment in relation to these guidelines.Aims and objectives To use registry data to: (1) investigate trends in survival and treatment; and (2) compare treatment with guidelines.Methods Registry data from three teaching hospitals were used to analyse trends in primary courses of treatment of breast (...) cancers during 1977–2003 (n = 4671), using univariate analyses and multiple logistic regression. Disease-specific survivals were analysed using Kaplan–Meier product limit estimates and multivariable Cox proportional hazards regression.Results The 5-year survival was 79.9%, but with a secular increase, reaching 83.6% in 1997–2003. The relative risk of death (95% confidence limits) was 0.74 (0.62, 0.88) for 1997–2003, compared with previous diagnoses, after adjusting for tumour node metastasis stage, grade, age and place of residence. Treatment changes included an increase in conservative surgery (as opposed to mastectomy) from 51.7% in 1977–1990 to 76.8% in 1997–2003 for stage I (P < 0.001) and from 31.1% to 52.2% across these periods for stage II (P < 0.001). Adjuvant radiotherapy also became more common (P < 0.001), with 20.6% of patients receiving this treatment in 1977–1990 compared with 60.7% in 1997–2003. Radiotherapy generally was more prevalent when conservative surgery was provided, although also relatively common in mastectomy patients when tumour diameters exceeded 50 mm or when there were four or more involved nodes. The proportion of patients receiving chemotherapy increased (P < 0.001), from 19.6% in 1977–1990 to 36.9% in 1997–2003, and the proportion having hormone therapy also increased (P < 0.001), from 34.3% to 59.4% between these periods.Conclusions Survivals appear to be increasing and treatment trends are broadly consistent with guideline directions, and the earlier research on which these recommendations were based.

It is commonly assumed that persons who hold abortions to be generally impermissible must, for the same reasons, be opposed to embryonic stem cell research [ESR]. Yet a settled position against abortion does not necessarily direct one to reject that research. The difference in potentiality between the embryos used in ESR and embryos discussed in the abortion debate can make ESR acceptable even if one holds that abortion is impermissible. With regard to their potentiality, in vitro embryos are here argued (...) to be more morally similar to clonable somatic cells than they are to in vivo embryos. This creates an important moral distinction between embryos in vivo and in vitro. Attempts to refute this moral distinction, raised in the recent debate in this journal between Alfonso Gómez-Lobo and Mary Mahowald, are also addressed. (shrink)

We demonstrate in this article how critical realism can be used to explain indeterminacy in role behaviour systematically. In so doing, we both rebut various criticisms of critical realism made recently by Kemp and Holmwood and attempt to illustrate the weaknesses and absences of approaches that concentrate unduly on the collection of expectations of actors concerning roles and the behaviour of incumbents. Within a framework that recognises that structure and agency are ontologically distinct but necessarily empirically related entities, we argue (...) that structures should be seen as sources of indeterminacy within role behaviour for at least four reasons: the co-determination of roles through the intersection of structures; conflicting role expectations caused by contradictions inhering within structures; asymmetries of power within social relations; and asymmetric repetition within structural reproduction/transformation. In light of this discussion of structural sources of indeterminacy, we then go on to demonstrate how critical realism is also able to analyse systematically the agential sources of indeterminacy within role behaviour and expectations through theories of psychobiography and reflexivity. We thus conclude that critical realism contains the conceptual tools required to illuminate the point of intersection between structure, culture and agency which is central to understanding both role behaviour and the plurality of expectations concerning such behaviour.

The claims that learning systems must build causal models and provide explanations of their inferences are not new, and advocate a cognitive functionalism for artificial intelligence. This view conflates the relationships between implicit and explicit knowledge representation. We present recent evidence that neural networks do engage in model building, which is implicit, and cannot be dissociated from the learning process.

An anxious resident paged ethics at 2:00 a.m. His patient, Mr. M, a twenty‐nine‐year‐old man with a history of multiple substance abuse, was in the hospital after cardiac arrest and lack of cerebral perfusion. Sadly, the young man probably met the criteria for brain death, but the final apnea test to confirm the diagnosis could not be done for another forty‐eight to seventy‐two hours because the Klonopin in his system might confound the results. The resident's concern, however, addressed a request (...) made by the patient's mother for a sperm harvest. The patient's mother maintained that her son had said he wanted to give her grandchildren. She wished to harvest sperm from him for a future use with an as‐yet‐to‐be‐determined surrogate mother. (shrink)

After people learn to sort objects into categories they see them differently. Members of the same category look more alike and members of different categories look more different. This phenomenon of within-category compression and between-category separation in similarity space is called categorical perception (CP). It is exhibited by human subjects, animals and neural net models. In backpropagation nets trained first to auto-associate 12 stimuli varying along a onedimensional continuum and then to sort them into 3 categories, CP arises as a (...) natural side-effect because of four factors: (1) Maximal interstimulus separation in hidden-unit space during autoassociation learning, (2) movement toward linear separability during categorization learning, (3) inverse-distance repulsive force exerted by the between-category boundary, and (4) the modulating effects of input iconicity, especially in interpolating CP to untrained regions of the continuum. Once similarity space has been "warped" in this way, the compressed and separated "chunks" have symbolic labels which could then be combined into symbol strings that constitute propositions about objects. The meanings of such symbolic representations would be "grounded" in the system's capacity to pick out from their sensory projections the object categories that the propositions were about. (shrink)

Balancing Change and Tradition in Global Education Reform is an invaluable resource for policymakers, faculty, students, and anyone interested in how decisions made about the education system ultimately affect the quality of education, educational access, and social justice.

Adam Morton, Stephen de Wijze, Hillel Steiner, and Eve Garrard have defended the view that evil action is qualitatively distinct from ordinary wrongdoing. By this, they do not that mean that evil actions feel different to ordinary wrongs, but that they have motives or effects that are not possessed to any degree by ordinary wrongs. Despite their professed intentions, Morton and de Wijze both offer accounts of evil action that fail to identify a clear qualitative difference between evil and (...) ordinary wrongdoing. In contrast, both Steiner's and Garrard's accounts of evil do point to qualitative distinctions between kinds of action, but it is implausible that either account correctly characterizes evil. The most plausible accounts maintain that evil actions have a necessary connection to extreme harms, and this suggests that evil is not qualitatively distinct from ordinary wrongdoing. (shrink)

In this book, Mumford and Anjum advance a theory of causation based on a metaphysics of powers. The book is for the most part lucidly written, and contains some interesting contributions: in particular on the necessary connection between cause and effect and on the perceivability of the causal relation. I do, however, have reservations about some of the book’s central theses: in particular, that cause and effect are simultaneous, and that causes can fruitfully be represented as vectors.

Sebbah’s noteworthy book is perhaps the first sustained inquiry into the relationship between three thinkers in the French phenomenological tradition, two of whom are well known in the Anglophone world (Levinas, Derrida) and one of whom (Henry) is gradually better understood by English-speaking audiences. That all three are arrayed together in this study makes it a pioneering enterprise and one that allows the English reader to apprise the worthiness of Henry’s association with his better-known compatriots.The strongest and most extensive portions (...) of the text focus on the three named figures in its subtitle, and in Part I Sebbah justifies his focus on these three in terms of a “family resemblance” (6–7) that they bear: Each in his own way practices phenomenology in the mode of excess, an excess that not only emerges in the style of each man’s writing but more fundamentally betrays a testing “of the limit, the limit through whose transgression alone excess can be what it is” (4).

The ‘cultural turn’ in social thought, and the rise of interpretive modes of social analysis, have raised the issue of how social criticism can legitimately be undertaken given the central role of actors’ understandings in constituting social reality. In this article I examine this issue by exploring debates around Winch’s interpretive approach. I suggest that Winch’s arguments usefully identify problems with external criticism, that is, criticism that attempts to contrast actors’ beliefs with the social world as it really is. However, (...) I also argue that Winch’s Wittgensteinian account of rule-following, on a plausible interpretation, places excessively strong restrictions on the possibility of internal criticism. In order to show the problems with such restrictions, I critically appraise two accounts of social criticism that are compatible with Winch’s arguments, those of Pleasants and Giddens, arguing that neither offers a satisfactory analysis. I then argue that if a viable notion of internal criticism is to be established Winch’s account of rule-following needs to be rejected. Having briefly offered an alternative, I suggest that it allows a more convincing conception of internal criticism, in which the understandings of actors can be criticized on the basis of their internal contradictions. The article then attempts to meet a possible objection to this position: that the logical judgements of contradiction and coherence required for immanent critique are not cross-culturally valid. I claim that such judgements are generally valid, and develop an argument for this position based on a critique of Lukes’s arguments. (shrink)

In Patterns of Discovery, [1], and Concept of the Positron, [2], the late N. R. Hanson put forward an intersting and, I believe, essentially sound argument to the effect that, necessarily, micro-entities are "unpicturable." Hanson's claim is centrally a claim about microreduction, but his use of the term 'unpicturable' may be misleading, generating critiques which overplay its implications and its importance. A. M. Paul, in a recent article, [4], has taken Hanson to task in this regard, claiming (...) that the notion of picturability is so cloudy as to render Hanson's whole enterprise unconvincing. In what follows I shall critically discuss Hanson's argument and Paul's analysis and attempt to state a version of it capable of meeting Paul's objections. I will claim that Hanson's use of the term 'unpicturable' may be, at worst, infelicitous, and that his thesis concerning micro- or property-reduction remains unaffected by questions concerning what we can or cannot picture.
