This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with 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 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.

This paper explores three cases of Do-It-Yourself, open-source technologies developed within the diverse array of topics and themes in the communities around the Public Laboratory for Open Technology and Science. These cases focus on aerial mapping, water quality monitoring and civic science practices. The techniques discussed have in common the use of accessible, community-built technologies for acquiring data. They are also concerned with embedding collaborative and open source principles into the objects, tools, social formations and data sharing practices that emerge (...) from these inquiries. The focus is on developing processes of collaborative design and experimentation through material engagement with technology and issues of concern. Problem-solving, here, is a tactic, while the strategy is an ongoing engagement with the problem of participation in its technological, social and political dimensions especially considering the increasing centralization and specialization of scientific and technological expertise. The authors also discuss and reflect on the Public Lab’s approach to civic science in light of ideas and practices of citizen/civic veillance, or “sousveillance”, by emphasizing people before data, and by investigating the new ways of seeing and doing that this shift in perspective might provide.

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 45, no. 1. © 2019 by Elisabeth Blair 173 How it feels is a series of questions Are you home now, or in the body of a bird? Do you drown, or do you sit calm in the watery air? And the fire—did you light it yourself, or did someone you know, or someone you have yet to meet? Can you sit quiet by it or (...) is it bridging the wet and dry with its feet, consuming your shoes first, then your eyes, skipping the topography in between in fickle pecking like chicken for grain? Is the shower water or is it fire? What if you want to feel something? Are you tired of time, to be so locked into now in this way, in the shower, and later in the circle, where they’ll say, We saw your scars, we know you were abused— it’s OK—we were too— —? But you had only scratched your back in the shower (accidentally) that day. Elisabeth Blair 174 Elisabeth Blair What is the fire that is the fire of drowning and what is the urgency that is the command of fog, saying you’d better sit down? You’d better stand up. Wood. Upholstery. Snow. Mud. These are real, while you are sinister, not believed. There were welts on your back; now they’ve gone. You try to explain: You had a belly once. You had a body. This place stores you in the leg of a bird, and not an invested one but a chicken, pecking, running lines in the ground. Most of the time is gone. You’re a stream down which a foundling comes. You’re a paramecium—all the hints and holds of life are here in you, but you are just a little one. You’re a mouth. You use yourself to laugh, to clutch your chin with one hand, rest the other on your knee. You use yourself to say no, I do not have scars—to clarify. You use yourself like the chicken in the yard uses itself to get by. Elisabeth Blair 175 Listen. I haven’t hit you. I’ve only used your body to demonstrate the richness of your feeling and the piracy inherent in your unwillingness to brave the feeling. I’ve only pulled you up. I’ve only sheltered you with a slap. I’ve dipped into your orange blood with my finger and felt relief—I know how to help. You listen to me— your blood will redden, then your face. You’ll get better. 176 Elisabeth Blair The English boy dwells in any of many neurodivergent states, no doubt undiagnosed. You only speak when spoken to by the staff, but he will and does speak—and laugh. He pulls his pants down and shits in the mess tent. You look at the grain in the rough wooden bench. He kicks as they tackle him to the ground, and all the while—as they swear and shout and he fights—comes that laughter, making ripples on your eyes. They put him in a sleeping bag, wrap a tarp around it, tie it with rope, then leave him on the ground for days, on display, in March, in the mountains, in many feet of snow. They call it a burrito. Let him laugh, they say, let him wiggle and roll.  [we were not killed]  [I am not ungrateful  I am not ungrateful] Elisabeth Blair 177 Age 16 A few years before, your horns newly removed, there had come a drought. Once you felt it, and felt yourself not just alone but marked— once on the forehead and once on either side where you had been but now were not— you developed doubts. You had intended to be reasonable, to talk. But the melting ice: there was no container. The evaporating water: there was no shade. No room to meet in. No family to group. No wits to gather or weave, nothing to save. Your hands became a precipice attached to a belief. The belief was mismanaged, had a bad day. Stuff clattered onto you. You lay there in the stuff and knew you had broken hearts. People... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:When Doctors Get It WrongKonrad BlairThe BeginningIt was a gloomy winter day as I sat in the back of the car while my father and mother drove me to another appointment in Pittsburgh. It was and wasn’t like so many car trips of my childhood for so many doctors’ appointments. The same deadening silence filled [End Page 89] the car as we drew closer to our destination. My parents (...) never discussed the appointments with me and I just learned to never ask. This appointment was different though; it came about as a result of request by a psychology professor who was conducting a follow–up study on individuals treated by the team of endocrinologists I saw as a child.The professor had reached out to me through my parents, since that was the only contact information available. It had been more than ten years since I had seen any of the doctors who treated me as a child. I was living in another state when I received the call from my mother informing me of the request for my participation in the study. I was really quite shocked; in all the years I was treated in early childhood and adolescence, no one had ever asked me how I felt about the treatment I received. I knew I had a medical condition, but no one ever explained to me why I needed so many appointments, and why I had to take medicine three times a day. No one told me why, when I was two or three years old, I had surgery that left me with memories of gauze and a catheter between my legs, or why medical residents still wanted to examine me, or why I had to be humiliated and ashamed, again and again. I was in my early 30’s by this time. Surely if my condition was so important that someone wanted to talk to me now, so many years later, the conversation would have already happened?!My parents dropped me off at the scheduled location for the interview. The professor introduced himself and his colleague. I didn’t recognize them, which meant they weren’t the doctors who had treated me. I remember feeling somewhat relieved, as I never liked the doctors who treated me as a child. I remembered my last appointment there, and feeling that I was escaping from captivity, that I was free to go on with my life.I wasn’t sure what to expect from this meeting. The professor told me that to date no one had completed any follow–up on the pediatric patients treated by the hospital’s endocrinology team to see how they were faring in life. He said he thought that was quite odd, so had decided to take on the project himself. He began by asking, “so, D_____, [I went by another name then] how are you doing at this point in your life?”I felt a sudden surge of rage, and, to my own surprise, I found myself responding angrily, “Why the hell do you care? It’s been over ten years and nobody, I mean nobody gives a rat’s ass as to how I’m doing and coping with the ramifications of the treatment I received from Dr. X.” Looking back, more than ten years after this meeting, I can see that I had been angry for a long time. I had been compliant and knew to play my role as a good girl. I had a good job, and I was married, but I knew I was far from happy.And so with that first question began what would be the long painful journey to discovering what had been hidden from me for over half my life, the source of my confusion and unparalleled frustration. What I had experienced throughout my childhood would permeate every aspect of my being and perception of myself for years to come. Every day I had to confront the effects of that experience just to live another day.The MiddleI was in shock and disbelief as I read and reread the letter my attorney presented to me from the very group of...

We make two suggestions with regard to Depue & Collins's target article. First, regarding the functioning of MOC13, we provide data indicating that, contrary to D&C's apparent position, this structure is not necessary for instrumental conditioning. Second, we suggest that D&C's approach would be advanced by reference to formal computational theory, in particular the work of Grossberg. We suggest that an integration of Grossberg 's and D&C's models can provide a more complete account of extraversion.

I am most grateful to James Blair and Justin D’Arms for commenting on my work. I would be hard put to name two other moral psychologists whose reactions I’d be so keen to hear. There is a striking asymmetry in their commentaries. Blair prefers a minimalist story about moral judgment, maintaining that the appeal to rules is unnecessary. D’Arms, by contrast, maintains that the account I offer is overly simple and that children lack moral concepts despite their partial (...) facility with moral language. It is tempting to treat my account as achieving the golden mean between Blair’s austerity and D’Arms’ extravagance. But it would be unfair to both. Blair is attracted to the sparse account for empirical reasons, and D’Arms is attracted to a richer account for philosophical reasons. Nonetheless, I still think that the account I offer is preferable to Blair’s minimalism and to D’Arms neosentimentalism. Rather than give a point-by-point reply, which would likely be tedious, I’ll try to say why I think that my account is still more plausible than the alternatives proffered by Blair and D’Arms.

This is an introduction to, and survey of, the constructive approaches to pure mathematics. The authors emphasise the viewpoint of Errett Bishop's school, but intuitionism. Russian constructivism and recursive analysis are also treated, with comparisons between the various approaches included where appropriate. Constructive mathematics is now enjoying a revival, with interest from not only logicans but also category theorists, recursive function theorists and theoretical computer scientists. This account for non-specialists in these and other disciplines.

In his paper “Scientific research is a moral duty”, John Harris argues that individuals have a moral duty to participate in biomedical research by volunteering as research subjects. He supports his claim with reference to what he calls the principle of beneficence as embodied in the “rule of rescue” , and the principle of fairness embodied in the prohibition on “free riding” . His view that biomedical research is an important social good is agreed upon, but it is argued that (...) Harris succeeds only in showing that such participation and support is a moral good, among many other moral goods, while failing to show that there is a moral duty to participate in biomedical research in particular. The flaws in Harris’s arguments are detailed here, and it is shown that the principles of beneficence and fairness yield only a weaker discretionary or imperfect obligation to help others in need and to reciprocate for sacrifices that others have made for the public good. This obligation is discretionary in the sense that the individuals are free to choose when, where, and how to help others in need and reciprocate for earlier sacrifices. That Harris has not succeeded in claiming a special status for biomedical research among all other social goods is shown here. (shrink)

The vegetation eaten by animals on large areas of several continents is deficient in phosphate and deleterious effects on physiology, particularly reproduction, ensue. Records on bone chewing behaviour by both pastoral andwild game animals extend over two centuries. In laboratory investigation of this apt behaviour it has been shown that the appetite for bones is innate and specific and cued predominantly by olfactory stimuli. It is suppressed by rapidly increasing the plasma phosphate concentration to normal but not influenced by increasing (...) the phosphate concentration in cerebrospinal fluid. The central organization of this genetically programmed behaviour appears to differ from systems subserving thirst and sodium appetite. (shrink)

The Intergovernmental Platform on Biodiversity and Ecosystem Services have recently launched themselves as the UN-sanctioned instrument for conserving nature. They seek to establish themselves as the authority in this field alongside the well-known Intergovernmental Panel on Climate Change in climate science. Quickly following or even before recent publication of their conceptual framework in two biology journals, they were already underway building upon it. This headlong push, we believe, is ill advised. We show how the framework is unsound as a foundation (...) for further work—in a number of ways and perhaps even by its authors’ own lights. It is therefore urgent that the IPBES thoroughly and thoughtfully reconsider their framework before too much effort is wasted. (shrink)

Originally published in 1986. Both moral philosophers and philosophical psychologists need to answer the question ‘what is a virtue?’ and the best answer so far give is that of Aristotle. This book is a rigorous exposition of that answer. The elements of Aristotle’s doctrine of virtue are scattered throughout his writings; this book reconstructs his complex and comprehensive doctrine in one place. It also covers Aristotle’s views about choice, character, emotions and the role of pleasure and pain in virtue. The (...) celebrated function is considered carefully as well as the doctrine of virtue being related to Aristotle’s metaphysics and categories. (shrink)

In this article we examine ethical aspects of the involvement of children in clinical research, specifically those who are incapable of giving informed consent to participate. The topic is, of course, not a new one in medical ethics but there are some tensions in current guidelines that, in our view, need to be made explicit and which need to be responded to by the relevant official bodies. In particular, we focus on tensions between the World Medical Association Declaration of Helsinki, (...) and the guidance offered by the British Medical Association, the Royal College of Paediatrics and Child Health , and the Council for International Organizations of Medical Sciences. We conclude with a call for these organisations to make their guidance explicit in relation to the World Medical Association Declaration. (shrink)

The manuscripts of Cicero's De oratore divide into two families: mutili and integri. The oldest representatives of the mutilated family are Avranches 238 , Erlangen 380 , and London, Harley 2736 . A and H are independent of each other, and the best witnesses to the text of the lost archetype . E too is considered to be an independent witness. Since the work of E. Ströbel, dating from the early eighties of the last century, the view has been generally (...) held that E, though closely related to A, is not a descendant of it but a copy of a ‘gemellus’ of A. The stemma devised by Ströbel has remained essentially the same to the present day. (shrink)

While there is significant consensus that undergraduate medical education should include bioethics training, there is widespread debate about how to teach bioethics to medical students. Educators disagree about course methods and approaches, the topics that should be covered, and the effectiveness and metrics for UME ethics training. One issue that has received scant attention is the timing of bioethics education during medical training. The existing literature suggests that most medical ethics education occurs in the pre-clinical years. Follow-up studies indicate that (...) medical students in their clinical rotations have little recall or ability to apply ethics concepts that were learned in their pre-clinical training. Trainees also report a desire for medical ethics to be taught in the context of practical application, which would suggest that the timing of pre-clinical ethics education is flawed. However, moving bioethics training to the clinical years should not be assumed to be the solution to the problems of recall and theory application. We argue that the effectiveness of timing bioethics education will depend on when medical students witness or experience particular categories of ethical dilemmas during their training. Our overarching hypothesis is that ethics education will be most effective when the bioethics training on a particular topic correlates to experiential exposure to that ethical issue. The purpose of our current study was to describe medical students exposure to particular categories of ethical conflicts, dilemmas, or issues. Our results may help bioethics educators better strategize about the most effective timing of medical ethics training in UME. (shrink)

This volume celebrates the centenary of the birth of Sarvepalli Radhakrishnan, India's leading philosopher of the twentieth century. Elected president of India in 1962, Radhakrishnan stressed the importance of creating a casteless and classless society in India, conveying his thoughts in extensive writings and numerous speeches. Including articles by twenty-nine leading scholars of Indian philosophy--many of whom knew Radhakrishnan personally--this collection is a critical examination of Radhakrishnan's contribution to the philosophy of religion and his role as an international statesman.

That Sallust owed a considerable debt to the writings of Cato the Censor was observed in antiquity, and the observation has often been discussed and expanded on by modern scholars. The ancient references to Sallust's employment of Cato are mainly in the context of his adoption of an archaic style, and specifically Catonian vocabulary. But the choice of Cato as a model had an obvious significance that went beyond the purely stylistic. Sallust's works articulate extreme pessimism at the moral state (...) of late-Republican Rome, and do so partly by contrasting the modern age with a prelapsarian time of near-untrammelled virtue, brought to an end only by the fall of Carthage and the consequent dominance of Roman power, which in turn led to moral corruption. Similarly, Cato famously stood in his own day for moral rectitude—and specifically appealed to past virtue as the standard to which he wished to hold his contemporaries. Sallust, by writing in a Catonian style, aligns himself with that tradition. (shrink)

When leading spectroscopists in Europe and America were engaged, during 1897, in exploring the recently-discovered Zeeman Effect, they were overtaken by a relatively obscure phsicist working in Dublin. Thomas Preston had previously been known only for his excellent textbooks. His achievement in discovering the Anomalous Zeeman Effect was immediately recognized, but his untimely death has deprived posterity until now of a full account of his life and qualities.

Tom Shakespeare’s important new book includes, among other topics, a persuasive critique of the social model of disability. A key component in his case against that model consists in an argument against the impairment/disability distinction as this is understood within the social model. The present paper focuses on the case Shakespeare makes against that distinction. Three arguments mounted by Shakespeare are summarised and responded to. It is argued that the responses adequately rebut Shakespeare’s case on this specific issue. Moreover, as (...) the engagement with Shakespeare’s argument illustrates, his claim to employ a critical realist perspective appears to be in considerable tension with the case he offers against the impairment/disability distinction.

Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all (...) regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole. (shrink)
