There is growing evidence that dopamine replacement therapy (DRT) used to treat Parkinson’s Disease can cause compulsive behaviours and impulse control disorders (ICDs), such as pathological gambling, compulsive buying and hypersexuality. Like more familiar drug-based forms of addiction, these iatrogenic disorders can cause significant harm and distress for sufferers and their families. In some cases, people treated with DRT have lost their homes and businesses, or have been prosecuted for criminal sexual behaviours. In this article we first examine the evidence (...) that these disorders are caused by DRT. If it is accepted that DRT cause compulsive or addictive behaviours in a significant minority of individuals, then the following ethical and clinical questions arise: Under what circumstances is it ethical to prescribe a medication that may induce harmful compulsive behaviours? Are individuals treated with DRT morally responsible and hence culpable for harmful or criminal behaviour related to their medication? We conclude with some observations of the relevance of DRT-induced ICDs for our understanding of addiction and identify some promising directions for future research and ethical analysis. (shrink)
To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)
People who have not experienced diseases and health conditions tend to judge them to be worse than they are reported to be by people who have experienced them. This phenomenon, known as the disability paradox, presents a challenge for health policy, and in particular, healthcare resource distribution. This divergence between patient and public preferences is most plausibly explained as a result of hedonic adaptation, a widespread phenomenon in which people tend to adapt fairly quickly to the state they are in, (...) good or bad, and adjust their baseline utility accordingly.If patient utilities can be shown to be inappropriate for use in public policy decision making, the disability paradox fades away. This paper offers a critique of one such attempt: the idea that adaptation leads to adaptive preferences. I argue that none of the main accounts of adaptive preferences in fact characterise adapted patient preferences as irrational. Adapted preferences should not, therefore, be treated as synonymous with adaptive preferences. I suggest that much patient adaptation should be understood as a form of the ubiquitous human ability to respond to environmental change. Consequently, we ought not to discount patient preferences.

This book provides a major new cross-disciplinary framework for thinking about poverty and human rights. Drawing on the fields of ethics, economics, and international law, Vizard demonstrates how the work of Nobel Laureate Amartya Sen has expanded and deepened human rights discourse across traditional disciplinary divides.
Using multisource data and multilevel analysis, we propose that the ethical stance of supervisors influences subordinates’ perceptions of corporate social responsibility which in turn influences subordinates’ trust in the organization resulting in their taking increased personal social responsibility and engagement in organizational citizenship behaviors oriented toward both the organization and other individuals. Using a multilevel model, we assessed the extent to which ethical leadership and CSR at the work unit level impacts subordinates’ behaviors mediated by organizational trust at the individual (...) level. We employed a sample of 71 work unit supervisors and 308 subordinates from five businesses of a conglomerate company located in mainland China. Subordinates were asked to rate supervisory ethical leadership practices, CSR, and their extent of organizational trust. Supervisors were asked to rate the personal social responsibility taking and OCB of their respective subordinates. A multilevel path analysis revealed that ethical leadership has a positive effect on CSR at the work unit level and that CSR has a positive cross-level effect on organizational trust at the individual level, which in turn significantly and positively impacts OCB through the mediating effect of taking personal social responsibility. Results are discussed in the context of China’s manufacturing sector. (shrink)
Public debate in Britain surrounding the cloning of Dolly the sheep has primarily focused on the legitimacy of cloning humans, not sheep. This bracketing of the human question relies on a distinction between humans and animals belied by the very constitution of transgenic animals who are made with human DNA, such as Polly. Moreover, the ways in which human beings think about, manipulate and classify animals have distinct cultural consequences, for example in relation to cultural understandings of life, property, (...) kinship and other forms of social interconnection. This article introduces the term 'breedwealth' to examine Dolly as a unique form of property in order to make some of these connections more visible. (shrink)
This study investigates whether the host personality and the primary alterpersonality of a woman with multiple personality disorder are controlled by the left and right hemispheres, respectively. Results support the hypothesis. Behavioral and preference measures indicate that Pe is strongly right handed and Pa is left handed. Verbal and musical dichotic tests show significantly greater accuracy for stimuli presented to the left ear for Pa and to the right ear for Pe. It is concluded that shifts in hemisphericity involve redistribution (...) of attentional resources and callosal suppression. “Conditional handedness” is proposed as a handedness subtype, characterizing persons who alternate personalities and consistently display alternate hand preferences linked to specific personality characteristics.

The logic of fiction has been a stand-alone research programme only since the early 1970s.1 It is a fair question as to why in the first place fictional discourse would have drawn the interest of professional logicians. It is a question admitting of different answers. One is that, since fictional names are “empty”, fiction is a primary datum for any logician seeking a suitably comprehensive logic of denotation. Another answer arises from the so-called incompleteness problem, exemplified by the fact (or (...) apparent fact) that some fictional sentences – think of “Sherlock Holmes’ mother was nick-named ‘Polly’” − are neither true nor false. These are sentences to command the attention of logicians who work on non-bivalent logics. A further spur to logical engagement is the supposed fictionality of certain kinds of ideal models in science and certain classes of mathematical objects. No doubt, there are other features of fictional discourse that provide the logician with a natural entré, but perhaps it would also be correct to say that the fiction’s biggest draw for logicians is that our quite common beliefs about the fictional constitute what Nicholas Rescher calls “aporetic clusters”, so named after the Latinized Greek aporos for “impassable”.2 An aporetic cluster is a set of claims such that..

ABSTRACTTask-irrelevant emotional expressions are known to capture attention, with the extent of “emotional capture” varying with psychopathic traits in antisocial samples. We investigated whether this variation extends throughout the continuum of psychopathic traits in a community sample. Participants searched for a target face among facial distractors. As predicted, angry and fearful faces interfered with search, indicated by slower reaction times relative to neutral faces. When fear appeared as either target or distractor, diminished emotional capture was seen with increasing affective-interpersonal psychopathic (...) traits. However, moderation analyses revealed that this was only when lifestyle-antisocial psychopathic traits were low, consistent with evidence suggesting that these two facets of psychopathic traits display opposing relationships with emotional reactivity. Anxiety did not show the predicted relationships with emotional capture effects. Findings show... (shrink)
The majority of commentators agree that the time to focus on embodiment has arrived and that the disembodied approach that was taken from the birth of artificial intelligence is unlikely to provide a satisfactory account of the special features of human intelligence. In our Response, we begin by addressing the general comments and criticisms directed at the emerging enterprise of deictic and embodied cognition. In subsequent sections we examine the topics that constitute the core of the commentaries: embodiment mechanisms, dorsal (...) and ventral visual processing, eye movements, and learning. (shrink)
Conventional portrayals of Athenian imperialism, heavily influenced by Thucydides, tend to assume that the Athenians thought of, and described, their imperialistic actions in frank, even brutal, terms. This article seeks to challenge that assumption by exploring two sets of fifth-century Athenian epigraphical material: documents which contain the phrase , and inscriptions imposing regulations on allied states which are erected at the ally's expense. In both cases, it is argued that if these apparently overtly aggressive documents are considered in an epigraphic (...) rather than a Thucydidean context, they reveal the existence of a more subtle, nuanced and diplomatic approach to imperial politics.

To add ethnographic perspective to Guala's arguments, I suggest reasons why experimental and ethnographic evidence do not concur and highlight some difficulties in measuring whether positive and negative reciprocity are indeed costly. I suggest that institutions to reduce the costs of maintaining cooperation are not limited to complex societies.
