In the developing world, the dramatic male bias in tobacco use is usually ascribed to pronounced gender disparities in social, political, or economic power. This bias might also reflect under-reporting by woman and/or over-reporting by men. To test the role of gender inequality on gender differences in tobacco use we investigated tobacco use among the Aka, a Congo Basin foraging population noted for its exceptionally high degree of gender equality. We also tested a sexual selection hypothesis—that Aka men’s tobacco use (...) is related to risk taking. Tobacco use, income, tobacco purchases, tobacco sharing, reasons for using tobacco, risk taking, and other variables were measured using structured surveys and peer reports. Tobacco use was verified by testing for salivary cotinine, a nicotine metabolite. Contrary to expectations, we found a very large male bias in tobacco use. Low levels of use among females appeared to be explained by aversions to tobacco, concerns over its negative effects on fetal health, and a desire to attract husbands, who prefer nonsmoking wives. High male use appeared to be related to a desire to enhance hunting abilities and attract and/or retain wives, who prefer husbands that smoke. We conclude that low levels of smoking by Aka women are better explained by the hypothesis that women evolved to avoid plant toxins to protect their fetuses and nursing infants. High male use might be better explained by sexual selection. We also highlight the important role that recreational drugs appear to play in hunter-gatherer sharing relationships. (shrink)

We applaud Müller & Schumann (M&S) for bringing needed attention to the problem of motivation for common non-addictive drug use, as opposed to the usual focus on exotic drugs and addiction. Unfortunately, their target article has many underdeveloped and sometimes contradictory ideas. Here, we will focus on three key issues.

A long-standing theoretical tradition in clinical psychology and psychiatry sees deliberate self-harm , such as wrist-cutting, as “functional”—a means to avoid painful emotions, for example, or to elicit attention from others. There is substantial evidence that DSH serves these functions. Yet the specific links between self-harm and such functions remain obscure. Why don’t self-harmers use less destructive behaviors to blunt painful emotions or elicit attention? Economists and biologists have used game theory to show that, under certain circumstances, self-harmful behaviors by (...) economic agents and animals serve important strategic goals. In particular, “costly signals” can credibly reveal a “private state” in situations where verbal claims and other “cheap” signals might be disbelieved. Here, DSH is scrutinized using signaling theory, and a variant, the theory of bargaining with private information. The social contexts and associated features of DSH suggest that it might be a costly, and therefore credible, signal of need that compels social partners to respond. (shrink)

Museum workers have taken a massive hit during the pandemic when many museums closed their doors, cut staff hours, instituted layoffs and furloughs, and pushed more into precarity. For many workers, the effect of the pandemic has highlighted long-standing issues of racial, economic, gender and political inequality. This article engages with how workers are responding to this insecurity by highlighting worker-led feminist mobilizations for transformation in museums based in the United States and the United Kingdom. By focusing on efforts for (...) engaging with the Black Lives Matter movement, decolonizing the museum, unionizing workers and providing mutual aid, this article examines worker-led practices of transformation of the museum amid crisis. A special emphasis is put on how workers articulate the importance of feminist solidarity and collective action in envisioning a more just museum of the future. (shrink)

Commonsense reasoning about the physical world, as exemplified by "Iron sinks in water" or "If a ball is dropped it gains speed," will be indispensable in future programs. We argue that to make such predictions (namely, envisioning), programs should use abstract entities (such as the gravitational field), principles (such as the principle of superposition), and laws (such as the conservation of energy) of physics for representation and reasoning. These arguments are in accord with a recent study in physics instruction where (...) expert problem solving is related to the construction of physical representations that contain fictitious, imagined entities such as forces and momenta (Larkin 1983). We give several examples showing the power of physical representations. (shrink)

Human-Computer Interaction (HCI) and games set a new domain in understanding people’s motivations in gaming, behavioral implications of game play, game adaptation to player preferences and needs for increased engaging experiences in the context of HCI serious games (HCI-SGs). When the latter relate with people’s health status, they can become a part of their daily life as assistive health status monitoring/enhancement systems. Co-designing HCI-SGs can be seen as a combination of art and science that involves a meticulous collaborative process. The (...) design elements in assistive HCI-SGs for Parkinson’s Disease (PD) patients, in particular, are explored in the present work. Within this context, the Game-Based Learning (GBL) design framework is adopted here and its main game-design parameters are explored for the Exergames, Dietarygames, Emotional games, Handwriting games, and Voice games design, drawn from the PD-related i-PROGNOSIS Personalized Game Suite (PGS) (www.i-prognosis.eu) holistic approach. Two main data sources were involved in the study. In particular, the first one includes qualitative data from semi-structured interviews, involving 10 PD patients and four clinicians in the co-creation process of the game design, whereas the second one relates with data from an online questionnaire addressed by 104 participants spanning the whole related spectrum, i.e., PD patients, physicians, software/game developers. Linear regression analysis was employed to identify an adapted GBL framework with the most significant game-design parameters, which efficiently predict the transferability of the PGS beneficial effect to real-life, addressing functional PD symptoms. The findings of this work can assist HCI-SG designers for designing PD-related HCI-SGs, as the most significant game-design factors were identified, in terms of adding value to the role of HCI-SGs in increasing PD patients’ quality of life, optimizing the interaction with personalized HCI-SGs and, hence, fostering a collaborative human-computer symbiosis.

This article presents results from a multidisciplinary research project on the integration and transfer of language knowledge into robots as an empirical paradigm for the study of language development in both humans and humanoid robots. Within the framework of human linguistic and cognitive development, we focus on how three central types of learning interact and co-develop: individual learning about one's own embodiment and the environment, social learning (learning from others), and learning of linguistic capability. Our primary concern is how these (...) capabilities can scaffold each other's development in a continuous feedback cycle as their interactions yield increasingly sophisticated competencies in the agent's capacity to interact with others and manipulate its world. Experimental results are summarized in relation to milestones in human linguistic and cognitive development and show that the mutual scaffolding of social learning, individual learning, and linguistic capabilities creates the context, conditions, and requisites for learning in each domain. Challenges and insights identified as a result of this research program are discussed with regard to possible and actual contributions to cognitive science and language ontogeny. In conclusion, directions for future work are suggested that continue to develop this approach toward an integrated framework for understanding these mutually scaffolding processes as a basis for language development in humans and robots.

Future robots should have common sense about the world in order to handle the problems they will encounter. A large part of this commonsense knowledge must be naive physics knowledge, since carrying out even the simplest everyday chores requires familiarity with physics laws. But how should one start codifying this knowledge? What kind of skills should be elicited from the experts (each and every one of us)? This paper will attempt to provide some hints by studying the mental models of (...) force and motion. (shrink)

As the title Ritual and Religion in the Xunzi accurately suggests, this collection of essays edited by T. C. Kline III and Justin Tiwald addresses Xunzi’s perspective on ritual and religion. Some of the essays are new, others are have been published previously. As a whole, the book strives to portray Xunzi as a religious philosopher, and to elucidate his potential contribution to the understanding of religion and ritual. Although there are a variety of views presented, Xunzi is generally characterized (...) as renovating and reinterpreting religion, rather than denouncing it, as he has sometimes been interpreted.After an introduction, the first chapter is Edward J. Machle’s seminal 1976 essay “Xunzi as a Religious.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Virtue, Nature, and Moral Agency in the XunziKurtis HagenVirtue, Nature, and Moral Agency in the Xunzi. Edited, with introduction, by T. C. Kline III and Philip J. Ivanhoe. Indianapolis: Hackett Publishing Company, 2000. Pp. xvii + 268.Virtue, Nature, and Moral Agency in the Xunzi, edited by T. C. Kline III and Philip J. Ivanhoe, is an anthology that has much to recommend it. It brings together several seminal (...) papers on Xunzi by established and distinguished scholars of Chinese philosophy, such as Antonio S. Cua, D. C. Lau, David S. Nivison, and Henry Rosemont, Jr. It also includes contributions from relative newcomers, who focused their dissertations on Xunzi's philosophy, namely T. C. Kline III and Eric Hutton. While most of these essays have been previously published, some appear in print for the first time in this volume. There is also a succinct introduction, name and subject indexes, and a targeted bibliography, which may serve as a reading list for those interested in supplementing their study of Xunzi. Another nicety is that references to passages in the Xunzi in older articles have been updated to include John Knoblock's translation1 as well as A Concordance to the Xunzi,2 and romanizations have been standardized to pinyin. [End Page 434]For the most part, the title Virtue, Nature, and Moral Agency in the Xunzi accurately represents the most prominent subject matter of the book. However, by "nature" what is meant is apparently "human nature," if that is an adequate translation for the concept Xunzi designates with the character xing. Xunzi's view of tian (the propensities of nature, the heavens) is not prominently discussed.3 Most of the essays, chapters 4 through 11 (the final chapter), deal extensively if not primarily with understanding Xunzi's conception of human nature. Chapters 5 through 7 are tied even closer together under the theme of moral agency (more on their connection below). Virtue is the topic of chapter 3 and plays a role in chapters 4 and 7.Although the first two chapters seem not to fall neatly within these categories, Henry Rosemont, Jr.'s contribution, "State and Society in the Xunzi: A Philosophical Commentary," seems an appropriate choice for the lead chapter of this collection. A sweeping polemic in defense of Xunzi's political philosophy, this seminal essay demonstrates the philosophical strength and potential relevance of Xunzi's thought. Specifically, Rosemont argues that Xunzi's political system is no less "reasonable" than democracy, and that while Xunzi advocates what Karl Popper would call a "closed society," Xunzi's system is defensible against Popper's critique of such societies.4The second chapter, "Ethical Uses of the Past in Early Confucianism: The Case of Xunzi," is authored by Antonio S. Cua, who has been a consistent contributor to the understanding of Xunzi's philosophy for more than twenty years. A collection of essays on Xunzi would be incomplete without Cua's work being represented. However, given the themes of the book, it is not entirely clear why this particular piece was selected. While Cua has written on both human nature and virtue in the Xunzi, this essay only tangentially addresses the theme of virtue. Nevertheless, it exemplifies the kind of careful scholarship characteristic of Cua's work, and there is something to be said for an anthology like this to exhibit breadth as well as focus. In his contribution, Cua analyzes Xunzi's appeal to history in terms of its "pedagogical function," "rhetorical function," "elucidative function," and "evaluative function."In chapter 3, "Virtues in Xunzi's Thought," Jonathan W. Schofer offers a lucid depiction of Xunzi's moral theory as a kind of virtue theory, despite the lack of any systematic analysis on Xunzi's part of a specific set of virtues. He then suggests that, given Xunzi's theory and goals, the omission of any analysis of specific virtues may have been deliberate.The last eight chapters deal extensively with the issue of human nature. Chapter 4, "Xunzi: Morality as Psychological Constraint," by Joel J. Kupperman, compares Xunzi's and Mencius' conceptions of human nature. Kupperman argues that, unlike Mencius, Xunzi does not really have a "view of human... (shrink)

The concept of noman in Hagen encompasses a local theory of consciousness, agency, and morality. Interview materials are given to illustrate notions of how the noman works. The Hageners recognize a kind of duality between mind and body but no fundamental split between them. Their theory of consciousness is also a theory of morality and ethics, as well as a recognition of creative agency in life. Key words: Mount Hagen, person, gender, body/mind.

Despite Christopher Stone’s recent argument on behalf of moral pluralism, the principal architects of environmental ethics remain committed to moral monism. Moral pluralism fails to specify what to do when two or more of its theories indicate inconsistent practical imperatives. More deeply, ethical theories are embedded in moral philosophies and moral pluralism requires us to shift between mutually inconsistent metaphysics of morals, most of which are no Ionger tenable in light of postmodern science. A univocal moral philosophy-traceable to David Hume’s (...) and Adam Smith’s theory of moral sentiments, grounded in evolutionary biology by Charles Darwin, and latterly extended to the environment by Aldo Leopold-provides a unified, scientifically supported world view and portrait of human nature in whichmultiple, lexically ordered ethics are generated by multiple human, “mixed,” and “biotic” community memberships.

Since Leibniz's time, Cartesian mental causation has been criticized for violating the conservation of energy and momentum. Many dualist responses clearly fail. But conservation laws have important neglected features generally undermining the objection. Conservation is _local_, holding first not for the universe, but for everywhere separately. The energy in any volume changes only due to what flows through the boundaries. Constant total energy holds if the global summing-up of local conservation laws converges; it probably doesn't in reality. Energy conservation holds (...) if there is symmetry, the sameness of the laws over time. Thus, if there are time-places where symmetries fail due to nonphysical influence, conservation laws fail there and then, while holding elsewhere, such as refrigerators and stars. Noether's converse first theorem shows that conservation laws imply symmetries. Thus conservation trivially nearly entails the causal closure of the physical. But expecting conservation to hold in the brain simply assumes the falsehood of Cartesianism. Hence Leibniz's objection begs the question. Empirical neuroscience is another matter. So is Einstein's General Relativity: far from providing a loophole, General Relativity makes mental causation _harder_. (shrink)

Although ecology is neither a universal nor foundational science, it has metaphysical implications because it profoundly alters traditional Western concepts of terrestrial nature and human being. I briefly sketch the received metaphysical foundations of the modem world view, set out a historical outline of an emerging ecological world view, and identify its principal metaphysical implications. Among these the most salient are a field ontology, the ontological subordination of matter to energy, internal relations, and systemic (as opposed to oceanic) holism. I (...) treat moral psychology as a special case of the metaphysical implications of ecology. Ecology undermines the concept of a separable ego or social atom and thus renders obsolete any ethics which involves the concepts of “self” and “other” as primitive terms. (shrink)

The capability approach constitutes a significant contribution to social theory but its potential is diminished by its insufficient treatment of the social construction of meaning. Social meanings enable people to make value judgements about what they will do and be, and also to evaluate how satisfied they are about what they are able to achieve. From this viewpoint, a person’s state of wellbeing must be understood as being socially and psychologically co-constituted in specific social and cultural contexts. In this light, (...) the telos of ‘living well’ which is at the heart of Sen’s version of the capability approach is inadequate and must be modified to a telos of ‘living well together’ which includes consideration of the social structures and institutions which enable people to pursue individual freedoms in relation to others. The policy significance of the capability approach can be further strengthened by paying greater consideration to the political economy of policy decision-making processes and the ways in which conflicts and distributions of power are institutionalized.

Hypnagogic and hypnopompic experiences (HHEs) accompanying sleep paralysis (SP) are often cited as sources of accounts of supernatural nocturnal assaults and paranormal experiences. Descriptions of such experiences are remarkably consistent across time and cultures and consistent also with known mechanisms of REM states. A three-factor structural model of HHEs based on their relations both to cultural narratives and REM neurophysiology is developed and tested with several large samples. One factor, labeled Intruder, consisting of sensed presence, fear, and auditory and visual (...) hallucinations, is conjectured to originate in a hypervigilant state initiated in the midbrain. Another factor, Incubus, comprising pressure on the chest, breathing difficulties, and pain, is attributed to effects of hyperpolarization of motoneurons on perceptions of respiration. These two factors have in common an implied alien ''other'' consistent with occult narratives identified in numerous contemporary and historical cultures. A third factor, labeled Unusual Bodily Experiences, consisting of floating/flying sensations, out-of-body experiences, and feelings of bliss, is related to physically impossible experiences generated by conflicts of endogenous and exogenous activation related to body position, orientation, and movement. Implications of this last factor for understanding of orientational primacy in self-consciousness are considered. Central features of the model developed here are consistent with recent work on hallucinations associated with hypnosis and schizophrenia. (shrink)

The Aristotle-Kant tradition requires that autonomous activity must originate within the self and points toward a new type of causation (different from natural efficient causation) associated with teleology. Notoriously, it has so far proven impossible to uncover a workable model of causation satisfying these requirements without an increasingly unsatisfying appeal to extra-physical elements tailor-made for the purpose. In this paper we first provide the essential reason why the standard linear model of efficient causation cannot support the required model of agency: (...) its causal thread model of efficient causation cannot support the core requirement that an action is determined by, and thus an expression of, the agent’s nature. We then provide a model that corrects these deficiencies, constructed naturalistically from within contemporary biology, and argue that it provides an appropriate foundation for all the features of genuine agency. Further, we provide general characterisations of freedom and reason suitable to this bio-context (but that also capture the core classical conceptions) and show how this model reconciles them.

Given the hundreds of articles and books that have been written in epistemology over the span of just the past few decades, relatively little has been written specifically on epistemic responsibility. What has been written rarely considers the nature of epistemic responsibility and its possible role in epistemic justification or knowledge. Instead, such work concerns philosophical analyses and arguments about related concepts such as epistemic virtues or duties, rather than epistemic praiseworthiness and blameworthiness.2 It is epistemic responsibility in the blameworthiness (...) and praiseworthiness senses that is the primary concern of this paper, though the duty sense of epistemic responsibility is explored in terms of its pertinence to epistemic virtue. What is epistemic responsibility? And what, if anything, is its relationship to justification and knowledge? (shrink)

This paper reviews the published empirical evidence concerning journal peer review consisting of 68 papers, all but three published since 1975. Peer review improves quality, but its use to screen papers has met with limited success. Current procedures to assure quality and fairness seem to discourage scientific advancement, especially important innovations, because findings that conflict with current beliefs are often judged to have defects. Editors can use procedures to encourage the publication of papers with innovative findings such as invited papers, (...) early-acceptance procedures, author nominations of reviewers, structured rating sheets, open peer review, results-blind review, and, in particular, electronic publication. Some journals are currently using these procedures. The basic principle behind the proposals is to change the decision from whether to publish a paper to how to publish it. (shrink)

A generalized traditional Western world view is compared with a generalized traditional American Indian world view in respect to the practical relations implied by either to nature. The Western tradition pictures nature as material, mechanical, and devoid of spirit (reserving that exclusively for humans), while the American Indian tradition pictures nature throughout as an extended family or society of living, ensouled beings. The former picture invites unrestrained exploitation of nonhuman nature, while the latter provides the foundations for ethical restraint in (...) relation to nonhuman nature. This conclusion is defended against disclaimers by Calvin Martin and Tom Regan. (shrink)

Part intellectual autobiography and part exposition of complex yet contemporary economic ideas, this lively conversation with renowned scholar and public intellectual Kenneth J. Arrow focuses on economics and politics in light of history, current events, and philosophy as well. Reminding readers that economics is about redistribution and thus about how we treat each other, Arrow shows that the intersection of economics and ethics is of concern not just to economists but for the public more broadly. With a foreword by Amartya (...) Sen, this book highlights the belief that government can be a powerful force for good, and is particularly relevant in the current political climate and to the lay reader as well as the economist.

Scientific realists contend that theory-conjunction presents a problem for empiricist conceptions of scientific knowledge and practice. Van Fraassen (1980) has offered a competing account of theory-conjunction which I argue fails to capture the mercenary character of epistemic dependence in science. Representative cases of theory-conjunction developed in the present paper show that mercenary reliance implies a "principle of epistemic symmetry" which only a realist can consistently accommodate. Finally, because the practice in question involves the conjunction of theories, a version of realism (...) more robust than the "entity realism" of Cartwright (1983, 1989) and Hacking (1983) is required to explain the success of theory-conjunction.
