This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they (...) showed an impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy. (shrink)

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the (...) class='Hi'>Intradimensional/ Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

Banded geckos (Coleonyx variegatus) were trained, at the rate of five daily trials, on eight intradimensional spatial shifts to a criterion of 80% correct per reversal. In contrast to several previously reported failures to obtain reversal learning, Coleonyx demonstrated significant improvement on both errors and trials to criterion. Their reversal performance compares favorably with that of birds and mammals and a common index of reversal ability, the mean total error, did not differentiate between taxa.

Arrow's account (1951/1963) of the problem of social choice is based upon the assumption that the preferences of each individual in the relevant group are expressible by a single ordering. This paper lifts that assumption and develops a multidimensional generalization of Arrow's framework. I show that, like Arrow's original framework, the multidimensional generalization is affected by an impossibility theorem, highlighting not only the threat of dictatorship of a single individual, but also the threat of dominance of a single dimension. In (...) particular, even if preferences are single-peaked across individuals within each dimension – a situation called intradimensional single-peakedness – any aggregation procedure satisfying Arrow-type conditions will make one dimension dominant. I introduce lexicographic hierarchies of dimensions as a class of possible aggregation procedures under intradimensional single-peakedness. The interpretation of the results is discussed. (shrink)

Two decades ago, in 1994, in the context of the 4th EU Framework Programme, ELSA was introduced as a label for developing and funding research into the ethical, legal and social aspects of emerging sciences and technologies. Currently, particularly in the context of EU funding initiatives such as Horizon2020, a new label has been forged, namely Responsible Research and Innovation. What is implied in this metonymy, this semantic shift? What is so new about RRI in comparison to ELSA? First (...) of all, for both labels, the signifier was introduced in a top-down manner, well before the concept that was signified by it had acquired a clear and stable profile. In other words, the signifier preceded the research strategies actually covered by these labels. Moreover, the newness of RRI does not reside in its interactive and anticipatory orientation, as is suggested by authors who introduced the term, but rather in its emphases on social-economic impacts.

Although there is good experimental evidence for the Aharonov–Bohm phase shift occurring when a solenoid is placed between the beams forming a double-slit electron interference pattern, there has been very little analysis of the relevant classical electromagnetic forces. These forces between a point charge and a solenoid involve subtle relativistic effects of order v 2 /c 2 analogous to those discussed by Coleman and Van Vleck in their treatment of the Shockley–James paradox. In this article we show that a (...) treatment exactly analogous to that given by Coleman and Van Vleck predicts classical electromagnetic forces which provide the basis for the Aharonov–Bohm phase shift. The magnetic force on the solenoid due to the passing charge leads to a displacement of the solenoid center of energy which must be balanced by the displacement of the passing charge. This classical displacement of the passing charge is exactly what is required to account for the Aharonov–Bohm phase shift. Also, we discuss a magnetic moment model which appears frequently in the literature and note that although the model provides conservation of linear momentum, it does not satisfy the general requirements for relativistic theories. We give an example suggesting that the new equation of motion for a magnetic moment proposed by Aharonov, Pearle, and Vaidman based upon the hidden momentum of the magnetic moment is completely inappropriate. Finally, we emphasize that the Aharonov–Casher phase shift is also explained by classical electromagnetic forces exactly parallel to those explaining the Aharonov–Bohm phase shift. (shrink)

In the 2016 film Doctor Strange, the title character undergoes a radical transition from successful neurosurgeon to highly skilled sorcerer. Unsurprisingly, he finds this transition difficult, in no small part because he thinks that sorcery seems somehow “unscientific.” Nevertheless, he eventually comes to adopt sorcery as wholeheartedly as he had embraced medicine. Some of his reasons for making this transition are personal, such as his desire to fix his injured hands and, later, to help others. Strange also displays the same (...) sorts of motivations that might drive any scientist: his intellectual curiosity drives him to understand how the Ancient One cured a paraplegic, and his desire to make a positive difference leads him to push the boundaries of sorcery. -/- This chapter will examine what Strange’s transition can teach us about the nature of scientific inquiry. More specifically, we’ll think about when it might make sense for scientists like Dr. Strange to change their approach. This will also allow us to explore what it means to practice science more generally. Some of what we learn might be surprising. For example, while it might seem obvious to us (and maybe even to Strange) that sorcery can’t count as a science, there are reasons for doubting this quick conclusion, at least in the sort of world that Dr. Strange lives in. Finally, we’ll consider what all of this means for science in our world, where things differ quite significantly. (shrink)

People often act in ways that appear incompatible with their sincere assertions. But how might we explain such cases? On the shifting view, subjects’ degrees of belief may be highly sensitive to changes in context. This paper articulates and refines this view, after defending it against recent criticisms. It details two mechanisms by which degrees of beliefs may shift.

It is widely agreed that Hume's description of human inductive reasoning is inadequate. But many philosophers think that this inadequacy in no way affects the force of Hume's argument for the unjustifiability of inductive reasoning. I argue that this constellation of opinions contains a serious tension, given that Hume was not merely pointing out that induction is fallible. I then explore a recent diagnosis of where Hume's sceptical argument goes wrong, due to Elliott Sober. Sober argues that Hume committed a (...) quantifier-shift fallacy, i.e. inferred a statement of ?? form from one of ?? form. The implications of this diagnosis for the traditional problem of induction are briefly examined. (shrink)

This article criticizes recent suggestions that the current ELSI research field should accommodate a new direction towards a ‘post-ELSI’ agenda. Post-ELSI research seeks to avoid the modernist division of responsibility for technical and social issues said to characterize ELSI research. Collaboration and integration are consequently the key terms of post-ELSI strategies that are to distinguish it from ELSI strategies. We argue that this call for a new direction relies on an inadequate generalized analysis of ELSI research as modern that will (...) affect the construal of post-ELSI strategies. We are concerned that the call for post-ELSI shift will exclude imaginative proposals and intellectual freedom by narrowing down the scope and methodologies of ELSI and thereby missing opportunities to play a critical and constructive normative role. Instead of framing current trends in ELSI research as a radical and progressive shift from ELSI to post-ELSI, we suggest an alternative story of expansion and diversification described in terms of a drift from ELSA 1 to ELSA 2, pertaining to acronyms in use in Europe. ELSI research has never been modern. It has been experimenting from the very start on ways to mesh the works of humanist, social and natural scientist in order to bridge and build alignments of emerging scientific and societal goals and matters of concern. The development from ELSA 1 to ELSA 2 expands in our account the range of intellectual and methodological capacities of analysis and engagement of complex and dynamic science-society relationships. We present three areas of ELSA expertise to illustrate that the expertise within the field builds on scholarly achievements within the humanities, social sciences as well as the natural sciences. The plurality of disciplinary background of ELSA researchers represents a valuable diversity that enables mutual criticism and formulations of complementary approaches that together constitute a viable ELSA field.

Writing is frequently analyzed as a mode of communication. But writing can be done for personal reasons, to remind oneself of things to do, of thoughts, of events. The cellphone has revealed this shift, commencing as a communication device and ending up as a memory prosthesis that records what we see, hear, read and think. The recordings are not necessarily for communicating a message to others, but sometimes just for oneself. Today, when machine learning algorithms read, write and transmit, (...) a new mode of communication arises that is not centered on the human. In this chapter the various phases of modern writing are modeled according to postphenomenology. As a branch of philosophy of technology, postphenomenology offers a set of analytical tools to study technologies and our relations to them. One of its central frameworks is the scheme of “I–technology–world.” The author proposes some modifications so that the scheme can systematically model the changes in the humans users, in machine learning algorithms imbued with non-human cognition and in the environments of readers, interlocutors and contexts.

Since the publication of Nikolas Rose’s ‘The Politics of Life Itself’ there has been vivid discussion about how biopolitical governance has changed over the last decades. This article uses what Rose terms ‘molecular politics’, a new socio-technical grip on the human body, as a contrasting background to ask anew his question ‘What, then, of biopolitics today?’ – albeit focusing not on advances in genetics, microbiology, and pharmaceutics, as he does, but on the rapid proliferation of wearables and other sensor-software gadgets. (...) In both cases, new technologies providing information about the individual body are the common ground for governance and optimization, yet for the latter, the target is habits of moving, eating and drinking, sleeping, working and relaxing. The resulting profound differences are carved out along four lines: ‘somatic identities’ and a modified understanding of the body; the role of ‘expert knowledge’ compared to that of networks of peers and self-experimentation; the ‘types of intervention’ by which new technologies become effective in our everyday life; and the ‘post-discipline character’ of molecular biopolitics. It is argued that, taken together, these differences indicate a remarkable shift which could be termed aretaic: its focus is not ‘life itself’ but ‘life as it is lived’, and its modality are new everyday socio-technical entanglements and their more-than-human rationalities of governance.

Commodification of health care is a central tenet of managed care as it functions in the United States. As a result, price, cost, quality, availability, and distribution of health care are increasingly left to the workings of the competitive marketplace. This essay examines the conceptual, ethical, and practical implications of commodification, particularly as it affects the healing relationship between health professionals and their patients. It concludes that health care is not a commodity, that treating it as such is deleterious to (...) the ethics of patient care, and that health is a human good that a good society has an obligation to protect from the market ethos.

Husserl’s philosophy of culture relies upon a person’s body being expressive of the person’s spirit, but Husserl’s analysis of expression in Logical Investigations is inadequate to explain this bodily expressiveness. This paper explains how Husserl’s use of “expression” shifts from LI to Ideas II and argues that this shift is explained by Husserl’s increased understanding of the pervasiveness of sense in subjective life and his increased appreciation for the unity of the person. I show how these two developments allow (...) Husserl to better describe the bodily expressiveness that is the source of culture. Husserl’s account of culture is thoroughly intentionalistic, but it does not emphasize thought at the expense of embodiment. Culture originates not in an abstract subjectivity, but by persons’ expressing themselves physically in the world. By seeing how Husserl develops his mature position on bodily expressiveness, we can better appreciate the meaningfulness and the bodily concreteness of cultural objects. (shrink)

Lara Buchak argues that her version of rank-weighted utilitarianism can accommodate an implication of the separateness of persons known as “the shift,” since it requires individuals to be more willing to accept risk for themselves than to accept inequality in society. I argue that this is mistaken. Buchak’s model fails to yield the shift when the decision-maker is distinct from the affected individual, as well as in certain social decisions where the risk attitude of the group is known. (...) These findings suggest that models which derive social choice rules from individual decision rules will generally fail to uphold separateness. (shrink)

This article considers the question of the responsibility of present generations for injustices committed by previous ones. It asks whether the descendants of victims of past injustice have claims against the descendants of the perpetrators of injustice. Two modes of argument are examined: the individual responsibility approach, according to which descendants cannot have claims against other descendants, and the collective responsibility approach, according to which descendants do have strong claims. Both approaches are criticized, but for different failings. An alternative view, (...) building on the individualist approach, is defended. This view argues that some people may have to bear responsibility for past injustice if lines of responsibility can clearly be drawn. This is most likely when certain kinds of corporate agents persist over generations, even after original members of such corporations have ceased to exist. Key Words: responsibility • justice • injustice • aborigines • history. (shrink)

In a survey of newspaper staff members shows that, although implementation of public journalism projects is widespread at U.S. daily newspapers, tibe majority of jou!rnalists still adhere to traditional values in journalism practice and do not support public journalism values that depart from traditional journalism. Criticism of public journalism is that it poses a danger to traditional professional values of independence and objectivity. In the great majority of comparisons, we found thot journalists supporting certain public journalism practices were at least (...) as sensitive to traditional ethical concerns as those who did not support public journalism.

Number facts are commonly assumed to be verbally stored in an associative multiplication fact retrieval network. Prominent evidence for this assumption comes from so-called operand-related errors (e.g. 4 × 6 = 28). However, little is known about the development of this network in children and its relation to verbal and non-verbal memories. In a longitudinal design, we explored elementary school children from grades 3 and 4 in a multiplication verification task with the operand-related and -unrelated distractors. We examined the contribution (...) of multiplicative fact retrieval by verbal and visuo-spatial short-term and working memory. Children in grade 4 showed smaller reaction times in all conditions. However, there was no significant difference in errors between grades. Contribution of verbal and visuo-spatial working memory also changed with grade. Multiplication correlated with verbal working memory and performance in grade 3 but with visuo-spatial working memory and performance in grade 4. We suggest that the relation to verbal working memory in grade 3 indicates primary linguistic learning of and access to multiplication in grade 3 which is probably based on verbal repetition of the multiplication table heavily practiced in grades 2 and 3. However, the relation to visuo-spatial semantic working memory in grade 4 suggests that there is a shift from verbal to visual and semantic learning in grade 4. This shifting may be induced because later in elementary school, multiplication problems are rather carried out via more written, i.e., visual tasks, which also involve executive functions. More generally, the current data indicates that mathematical development is not generally characterized by a steady progress in performance; rather verbal and non-verbal memory contributions of performance shift over time, probably due to different learning contents.

Management theory and practice are facing unprecedented challenges. The lack of sustainability, the increasing inequity, and the continuous decline in societal trust pose a threat to ‘business as usual’. Capitalism is at a crossroad and scholars, practitioners, and policy makers are called to rethink business strategy in light of major external changes. In the following, we review an alternative view of human beings that is based on a renewed Darwinian theory developed by Lawrence and Nohria. We label this alternative view (...) ‘humanistic’ and draw distinctions to current ‘economistic’ conceptions. We then develop the consequences that this humanistic view has for business organizations, examining business strategy, governance structures, leadership forms, and organizational culture. Afterward, we outline the influences of humanism on management in the past and the present, and suggest options for humanism to shape the future of management. In this manner, we will contribute to the discussion of alternative management paradigms that help solve the current crises. (shrink)
