Psychedelics have been recognized as model interventions for studying altered states of consciousness. However, few empirical studies of the shamanic state of consciousness, which is anecdotally similar to the psychedelic state, exist. We investigated the neural correlates of shamanic trance using high-density electroencephalography (EEG) in 24 shamanic practitioners and 24 healthy controls during rest, shamanic drumming, and classical music listening, followed by an assessment of altered states of consciousness. EEG data were used to assess changes in absolute power, connectivity, signal (...) diversity, and criticality, which were correlated with assessment measures. We also compared assessment scores to those of individuals in a previous study under the influence of psychedelics. Shamanic practitioners were significantly different from controls in several domains of altered states of consciousness, with scores comparable to or exceeding that of healthy volunteers under the influence of psychedelics. Practitioners also displayed increased gamma power during drumming that positively correlated with elementary visual alterations. Furthermore, shamanic practitioners had decreased low alpha and increased low beta connectivity during drumming and classical music and decreased neural signal diversity in the gamma band during drumming that inversely correlated with insightfulness. Finally, criticality in practitioners was increased during drumming in the low and high beta and gamma bands, with increases in the low beta band correlating with complex imagery and elementary visual alterations. These findings suggest that psychedelic drug-induced and non-pharmacologic alterations in consciousness have overlapping phenomenal traits but are distinct states of consciousness, as reflected by the unique brain-related changes during shamanic trance compared to previous literature investigating the psychedelic state.

Is Anscombean practical knowledge independent of what the agent actually does on an occasion? Failure to understand Anscombe’s answer to this question is a major obstacle to appreciating the subtlety and plausibility of her view. I argue that Anscombe’s answer is negative, and turns on the nature of mistakes in performance, and reveals a distinctive implicit metaphysics of mind and knowledge, structured by related capacities and exercises of capacities. If my interpretation is correct, then practical knowledge shares features with knowledge-how (...) and knowledge-that, but deserves its own epistemic category. (shrink)

The aim of this Swedish study was to develop the concept of moral sensitivity in health care practice. This process began with an overview of relevant theories and perspectives on ethics with a focus on moral sensitivity and related concepts, in order to generate a theoretical framework. The second step was to construct a questionnaire based on this framework by generating a list of items from the theoretical framework. Nine items were finally selected as most appropriate and consistent with the (...) research team’s understanding of the concept of moral sensitivity. The items were worded as assumptions related to patient care. The questionnaire was distributed to two groups of health care personnel on two separate occasions and a total of 278 completed questionnaires were returned. A factor analysis identified three factors: sense of moral burden, moral strength and moral responsibility. These seem to be conceptually interrelated yet indicate that moral sensitivity may involve more dimensions than simply a cognitive capacity, particularly, feelings, sentiments, moral knowledge and skills.

This collection reports on the latest research on an increasingly pivotal issue for evolutionary biology: cooperation. The chapters are written from a variety of disciplinary perspectives and utilize research tools that range from empirical survey to conceptual modeling, reflecting the rich diversity of work in the field. They explore a wide taxonomic range, concentrating on bacteria, social insects, and, especially, humans. -/- Part I (“Agents and Environments”) investigates the connections of social cooperation in social organizations to the conditions that make (...) cooperation profitable and stable, focusing on the interactions of agent, population, and environment. Part II (“Agents and Mechanisms”) focuses on how proximate mechanisms emerge and operate in the evolutionary process and how they shape evolutionary trajectories. Throughout the book, certain themes emerge that demonstrate the ubiquity of questions regarding cooperation in evolutionary biology: the generation and division of the profits of cooperation; transitions in individuality; levels of selection, from gene to organism; and the “human cooperation explosion” that makes our own social behavior particularly puzzling from an evolutionary perspective.

Responsible leadership is rare. It is not that most leaders are irresponsible, but responsibility in leadership is frequently defined so that an important connotation of responsible leadership is ignored. This article equates responsible leadership with virtuousness. Using this connotation implies that responsible leadership is based on three assumptions—eudaemonism, inherent value, and amplification. Secondarily, this connotation produces two important outcomes—a fixed point for coping with change, and benefits for constituencies who may never be affected otherwise. The meaning and advantages of responsible (...) leadership as virtuous leadership are discussed. (shrink)

Alvarez and Steward think the power of agency is a two-way power; Lowe thinks the will is. There is a problem for two-way powers. Either there is a unified description of the manifestation-type of the power, or not. If so, two-way powers are really one-way powers. If not, two-way powers are really combinations of one-way powers. Either way, two-way powers cannot help distinguish free agents from everything else. I argue the problem is best avoided by an Aristotelian view, which posits (...) a distinctive unity of explanation proper to two-way powers, grounded in a distinctive form of reasoning. (shrink)

This paper offers a critique of the view that causation can be analyzed in terms of explanation. In particular, the following points are argued: a genuine explanatory analysis of causation must make use of a fully epistemological-psychological notion of explanation; it is unlikely that the relatively clear-cut structure of the causal relation can be captured by the relatively unstructured relation of explanation; the explanatory relation does not always parallel the direction of causation; certain difficulties arise for any attempt to construct (...) a nonrelativistic relation of causation from the essentially relativistic relation of explanation; and to analyze causation as explanation is to embrace a form of “causal idealism”, the view that causal connections are not among the objective features of the world. The paper closes with a brief discussion of the contrast between the two fundamentally opposed viewpoints about causality, namely causal idealism and causal realism. (shrink)

This paper discusses in broad terms the metaphysical projects of Sydney Shoemaker’s Physical Realization . Specifically, I examine the effectiveness of Shoemaker’s novel “subset” account of realization for defusing the problem of mental causation, and compare the “subset” account with the standard “second-order” account. Finally, I discuss the physicalist status of the metaphysical worldview presented in Shoemaker’s important new contribution to philosophy of mind and metaphysics.

Within paleoanthropology, the origin of behavioral modernity is a famous problem. Very large-brained hominins have lived for around half a million years, yet social lives resembling those known from the ethnographic record appeared perhaps 100,000 years ago. Why did it take 400,000 years for humans to start acting like humans? In this article, I argue that part of the solution is a transition in the economic foundations of cooperation from a relatively undemanding form, to one that imposed much more stress (...) on human motivational and cognitive mechanisms. The rich normative, ceremonial, and ideological lives of humans are a response to this economic revolution in forager lives; from one depending on immediate return mutualism to one depending on delayed and third-party reciprocation.

The subsistence technology of forager communities has varied greatly over space and time. This paper (i) reviews briefly the main causal factors the literature identifies as responsible for this variation; (ii) analyzes in some detail the most prominent idea in the literature on spatial variation:Complex technology is an adaptive response to elevated risks of subsistence failure; (iii) it argues that the alleged empirical support for this hypothesis depends on dubious proxies of risk; (iv) it argues that it fails to explain (...) the subsistence technologies of desert foragers, who generally live with simple technologies in high‐risk environments; (v) it offers an alternative analysis, based on the reduced opportunity costs of complex technologies in highly seasonal environments, on the high value of typical forager targets in those environments and their relatively predictable location in space and time; and (v) the paper concludes with a conjecture about the role of environmental variation in toolkit change over deep time.

The standard view of the function of reason is that it emerged to enable individuals to make better judgements and choices. Once individuals could think better, and once we had suitable communicative tools, individual reasoning acquired a public face; we reasoned together as well as privately, in our own mind. Hugo Mercier and Dan Sperber argue that this gets the story the wrong way around: reasoning evolved for public purposes: to persuade, negotiate, assess. Once it was established publically, perhaps it (...) acquired a private function too. With the exception of a few minor complaints, this evolutionary case is well made. However, Mercier and Sperber embed their evolutionary case within a modular view of the mind and suggest a modular view of public reasoning itself. While I find the evolutionary case persuasive, I am sceptical of the cognitive science framework. (shrink)

Change is inevitable, and increasingly rapid and continuous in healthcare as organizations strive to adapt, improve and innovate. Organizational change challenges healthcare providers because it restructures how and when patient care delivery is provided, changing ways in which nurses must carry out their work. The aim of this doctoral study was to explore frontline nurses’ experiences of living with rapid and continuous organizational change. A critical hermeneutic approach was utilized. Participants described feeling voiceless, powerless and apolitical amidst rapid and continuous (...) organizational changes which fuelled apathy, cynicism and disengagement from the organization. However, critical analysis of the data showed that nurses actively engaged with power, voice and politics through resistant and transgressive behaviours in micro‐ethical moments of practice. There is a need to reconceptualize the concepts of voice, power and politics in nursing as there is dissonance between nurses’ beliefs about these concepts and what they are enacting in practice. Recognizing their enactment of power, voice and political agency at the micro‐level may empower nurses. Empowerment would mitigate the high levels of reports of powerlessness experienced in practice during organizational changes. (shrink)

Who should have a right to participate in a polity’s decision-making? Although the answers to this ‘boundary problem’ in democratic theory remain controversial, it is widely believed that the enfranchisement of tourists and children is unacceptable. Yet, the two most prominent inclusion principles in the literature – Robert Goodin’s ‘all (possibly) affected interests’-principle and the ‘all subjected to law’-principle – both enfranchise those groups. Unsurprisingly, democratic theorists have therefore offered several reasons for nonetheless exempting tourists and children from the franchise. (...) In this paper, I argue that their attempts fail. None of the proposed rationales can do the job without having unacceptable implications for the voting rights of other groups. I then develop a new specification of the affected interests-view, one that avoids such problems. According to my life plan-principle, a person is entitled to participate in a polity’s decision-making if and only if its decisions will actually affect her autonomously chosen life plans, or prevent her from developing or revising plans of that kind. I show that this principle straightforwardly avoids enfranchising tourists and children, and thus improves upon its two prominent rivals. The paper ends by considering and rejecting two objections to my new principle. (shrink)

This essay aims to delineate Mengzi’s view of emotion by analyzing his first ethical sprout, often referred to by the Chinese term cèyǐn zhī xīn 惻隱之心.Previous scholars usually translate this term as “compassion,” “sympathy,” or “commiseration,” in the sense of the painful feeling one feels at the misfortune of others. My goal in this article is to clarify the nature of this painful feeling, and specifically I argue that (1) cèyǐn zhī xīn is primarily construing another being’s misfortune with sympathetic (...) concern, and that (2) the painfulness of cèyǐn zhī xīn comes from this concern-based construal of the object of one’s compassion. My interpretation of cèyǐn zhī xīn as a concern-based construal is an attempt to construct an important alternative to the inclinational view of Mengzian emotions, and it could be also considered as making a crucial step toward a new interpretation of the Mengzian theory of emotional cultivation.

In this paper, we study the notions related to tree property 1 , or, equivalently, SOP2. Among others, we supply a type-counting criterion for TP1 and show the equivalence of TP1 and k- TP1. Then we introduce the notions of weak k- TP1 for k≥2, and also supply type-counting criteria for those. We do not know whether weak k- TP1 implies TP1, but at least we prove that each weak k- TP1 implies SOP1. Our generalization of the tree-indiscernibility results in (...)

Involuntary autobiographical memories are conscious memories of personal events that come to mind with no preceding attempts at retrieval. It is often assumed that such memories are closely related to current concerns – i.e., uncompleted personal goals. Here we examined involuntary versus voluntary autobiographical memories in relation to earlier registered current concerns measured by the Personal Concern Inventory . We found no differences between involuntary and voluntary memories with regard to frequency or characteristics of current concern-related contents. However, memories related (...) to current concerns were rated as more central to the person’s identity, life story and expectations for the future than non-concern-related memories, irrespective of mode of recall. Depression and PTSD symptoms correlated positively with the proportion of current concern-related involuntary and voluntary memories. The findings support the view that involuntary and voluntary remembering is subject to similar motivational constraints. (shrink)

This paper investigates whether corporate philanthropic decisions are associated with a firm’s listing status and business group affiliation. Analyzing a large sample of public and private firms in Korea, we find that public firms make more charitable contributions than private firms and business group-affiliated firms make more charitable contributions than non-affiliated firms. The results suggest that public firms, owing to greater public scrutiny, and business groups, owing to higher political costs, are encouraged to make more corporate charitable contributions. Further, we (...) find that greater corporate giving by public firms than private firms is more pronounced for business group-affiliated firms, compared with non-affiliated firms. The result is consistent with business groups’ strategic coordination of their affiliates’ philanthropic decisions to tunnel business group resources out to controlling shareholders who hold a larger portion of private affiliates than public affiliates.

Jackson says that the form of physicalism that I recommend, with certain emendations he believes are necessary, turns out to be none other than the “Australian” type-type identity theory of J.J.C. Smart and others. About this, too, I have no serious disagreement, although Jackson’s claim appears to depend, at least in part, on a certain chosen reading of the texts involved. In fact, one point of similarity may be worth noting. As I take it, one special feature of the “Australian” (...) type identity theory is the claim that mental-physical identities are contingent, not necessary. Suppose M has a single physical realizer, P. On my account, the statement that M = P is not metaphysically or logically necessary. It is contingent since the statement that P realizes M is contingent. This is so because for P to realize M is for it to fulfill the causal specification that defines M, and what causal relations P actually enters into is a question that depends on the laws prevailing in a given world. Thus, P may be a realizer of M in this world but perhaps not in another in which different laws hold; in some worlds M may have no realizers at all. None of this is in violation of the idea that identities are necessary. For, according to me, if M has realizers, M is a functional property defined by a causal specification. This means that “M” is not a rigid designator, though it is, as we might call it, “nomologically rigid” or “semi-rigid”. (shrink)

This study viewed students majoring in public relations as prospective public relations practitioners and explored their perceptions about corporate social responsibility (CSR) as their job attraction condition. The results showed that the students perceived CSR to be an important ethical fit condition of a company. One of the significant findings is that CSR can be an effective reputation management strategy for prospective employees, particularly when a company’s business is suffering. In examining the effect of CSR efforts on attitudinal and behavioral (...) outcomes, person–organization (P–O) fit appeared to serve as a mediator between CSR performances and organizational attractiveness.

This book begins with a survey of various readings of Locke as a materialist, as a substance dualist, and as a property dualist, and demonstrates that these inconsistent interpretations result from a general failure of modern commentators to notice the significance of Locke’s ‘mind-body nominalism’. By illuminating this largely overlooked aspect of Locke’s philosophy, this book reveals a common mistake of previous interpretations: that of treating what Locke conceives to be ‘nominal’ as real. The nominal symmetry that Locke posits between (...) mind and body is distinct from any form of metaphysical dualism, whether substance dualism or property dualism. It is a brand of naturalism, but does not insist that the material is ontologically more basic than the mental or that the former determines the latter. On this view, the material and the mental both relate solely to a certain set of functional roles, rather than to an intrinsic property that plays these roles. The term ‘matter’ is thus rendered vague, and materialism is conceived as a precariously grounded ontological doctrine. Elaborating on this interpretation of Locke’s Essay, this book examines the insightful readings of Locke developed by seventeenth- and eighteenth-century thinkers such as Richard Burthogge, William Carroll, and Joseph Priestley. This book also seeks to clarify what Locke’s position would look like in a modern setting by noting some significant parallels with the ideas of leading contemporary philosophers such as Donald Davidson, David Lewis, and Colin McGinn.

The aim of this essay is to introduce scholars to recent discussions of early Confucian ethics that intersect with contemporary moral psychology. Given the early Confucian tradition's intense focus on the cultivation of virtue, there are a number of ways in which early Confucian thinkers – as represented in the texts of the Analects, the Mencius, and the Xunzi – fruitfully engaged in a range of topics that are closely connected to live issues in moral psychology. Not only did they (...) anticipate some contemporary debates but explored them from a distinctively Confucian normative worldview, attending especially to the role of the family and ritual practice. This essay seeks to demonstrate that early Confucianism, by integrating a normative vision with empirically grounded observations of human behavior, offers resources for constructively exploring a number of ongoing questions in moral psychology.

Although Fair Trade has recently experienced rapid growth around the world, there is lack of consumer research that investigates what determines consumers' loyalty toward Fair Trade brands. In this research, we investigate how ethical consumption values (ECV) and two mediating variables, Fair Trade product beliefs (FTPB) and Fair Trade corporate evaluation, (FTCE) determine Fair Trade brand loyalty (FTBL). On the basis of two empirical studies that use samples from the U.S. and Korea, we provide evidence demonstrating that the manner in (...) which ECV influence FTBL differs in the U.S. and Korea. In the U.S., ECV determine FTBL only indirectly via FTPB, whereas in Korea they determine FTBL directly as well as indirectly via FTCE. We discuss theoretical and managerial implications of these findings. (shrink)

This paper responds to Birch and Buskell's thoughtful critique. In it, I defend my use of behavioural ecology. I argue, contra Birch and Buskell, that I can give a principled defence of the emergence of conventions for respecting property, modelling as a network of pairwise iterated PDs between incipient farmers. Second, I defend my scepticism about the power of cultural group selection to optimise community normative packages. Finally, I located my views, as requested, against those of The dawn of everything. (...) I argue that the more complex “original position” envisaged in Dawn depends on special conditions rarely found on Pleistocene Africa. (shrink)

Depression experienced by older adults is proving an increasing global health burden, with rates generally 7% and as high as 27% in the USA. This is likely to significantly increase in coming years as the number and proportion of older adults in the population rises all around the world. Therefore, it is imperative that the effectiveness of approaches to the prevention and treatment of depression are understood. Creative arts interventions, including art, dance movement, drama and music modalities, are utilised internationally (...) to target depression and depressive symptoms in older adults. This includes interventions led by trained arts therapists as well as other health and arts professionals. However, to date there has not been a systematic review that reports effects and examines the processes (why) and mechanisms (how) of creative arts interventions are used to address depression in this older age group. This systematic review of studies on creative arts interventions for older adults experiencing depression examined: outcomes of four creative arts modalities (art, dance movement, drama, and music); with particular attention paid to processes documented as contributing to change in each modality; and mechanisms considered to result from these processes. Our analysis of 75 articles (17 art, 13 dance, 4 drama and 41 music) indicates mostly significant quantitative or positive qualitative findings, particularly for interventions led by creative arts therapists. Mechanisms of change gleaned from the studies that were common across modalities include physical (e.g. increased muscle strength; neurochemical effects, such as endorphin release), intra-personal (e.g. enhanced self-concept, strengthened agency and mastery; processing and communication of emotions), cultural (e.g. creative expression, aesthetic pleasure), cognitive (e.g. stimulation of memory) and social (e.g. increased social skills and connection), that were all considered to contribute to reduced depression and symptoms. Recommendations for future research include a stronger focus on testing of processes and mechanisms. (shrink)

ABSTRACT:In this article I inquire into Confucian ethics from a non-ideal stance investigating the complex interaction between Confucian ideals and the reality of the modern workplace. I contend that even Confucian workers who regularly engage in social rites at the workplace have an internal, Confucian reason to appreciate the value of rights at the workplace. I explain, from a Confucian non-ideal perspective, why I disagree with the presumptuous idea that labor (or workplace) rights are necessarily incompatible with Confucian ideals and (...) values. Specifically, I argue that if managers were “sages,” the highest moral exemplars and authorities in the Confucian tradition, they would perceive that social rituals alone are often not a contextually intelligent and valued response for the development of intimate communities in the modern workplace. The sage perspective will lead Confucian managers to realize, from their own moral perspective, that they have good reason to balance rites with rights, so long as the adoption is extrinsically valuable and consistent with the Confucian ideal. This article contributes to the debates about Confucianism's compatibility with rights, helps Western human rights scholars better contextualize their arguments in Confucianism-influenced cultures, and contributes to the development of a Confucian or Chinese approach to business ethics.

The current paper examines whether knowledge of an ethical principle influences moral awareness and ethical decision making. Using hypothetical scenarios and a behavioral task, three experiments examine the effects of deepening people’s knowledge of ethical principles. In each study, an analogical encoding learning intervention led to greater knowledge of an ethical principle, which in turn resulted in a greater likelihood of moral awareness and making ethical decisions. These findings suggest that moral awareness is partly a matter of the depth of (...) individuals’ knowledge of ethical principles. The findings provide further reasons to link work on ethics with work on expertise and knowledge transfer as well as indicate new approaches to ethics training. (shrink)

This paper argues that democratic collectives have reason to increase the voting power of their younger members. It first presents an intuitive case for weighted voting in general, before drawing support from a prominent principle of democratic inclusion – the all-affected principle. On a plausible understanding of that principle, a decision may affect people to varying degrees, and this variation should be reflected in the strength of their say. The paper then argues that exposure time to a decision’s effects is (...) typically a good proxy for tracking such variation, such that collectives have reason to gradually reduce their members’ voting power as they grow older. This holds, for example, in the ordinary parliamentary elections in representative democracies. It is then argued that we may build a similar case for age-weighting on a plausible version of the all-affected principle’s main rival, the all-subjected principle. The paper ends by addressing various objections. It argues that none of them undermine the case for age-weighting, and that some might even support age-weighting over its non-weighted (‘one person, one vote’) alternative. (shrink)

While it is well known that Zhuangzi uses metaphor extensively, there is much less appreciation of the role that it plays in his thought-a topic that is investigated in this essay.

Comparisons are made between a central metaphorical structure in the Zhuangzi on the one hand and contemporary views of the nature of metaphor by Donald Davidson and by Lakoff and Johnson on the other. (...) It is hoped that these comparisons will help to illuminate the central metaphorical structure and its role in the philosophy of the Zhuangzi. (shrink)

In the U.S. there has been considerable interest in connecting low-income households to alternative food networks like Community Supported Agriculture. To learn more about this possibility we conducted a statewide survey of CSA members in California. A total of 1149 members from 41 CSAs responded. Here we answer the research question: How do CSA members’ socioeconomic and demographic backgrounds, household conditions potentially interfering with membership, and CSA membership experiences vary between lower-income households and higher-income households? We divided members into LIHHs (...) and HIHHs. We present comparisons of LIHHs’ and HIHHs’ employment, race/ethnicity, household composition and education, use of food support, and enjoyment of food-related activities; conditions interfering with membership and major life events; and sources of information influencing decision to join, reasons for joining, ratings of importance of and satisfaction with various CSA attributes, gaps between importance of and satisfaction with various CSA attributes, valuing of the share and willingness to pay more, and impacts of membership. We find that LIHHs are committed CSA members, often more so than HIHHs, and that CSA members in California are disproportionately white, but that racial disproportionality decreases as incomes increase. We conclude by considering: the economic risks that LIHHs face in CSA membership, the intersection of economic risks with race/ethnicity and cultural coding in CSA; and the possibilities of increasing participation of LIHH in CSA.

There is a very striking difference between even the simplest ethnographically known human societies and those of the chimps and bonobos. Chimp and bonobo societies are closed societies: with the exception of adolescent females who disperse from their natal group and join a nearby group (never to return to their group of origin), a pan residential group is the whole social world of the agents who make it up. That is not true of forager bands, which have fluid memberships, and (...) regular associations with neighbouring bands. They are components of a larger social world. The open and fluid character of forager bands brings with it many advantages, so the stability of this more vertically complex form of social life is not difficult to explain, once it establishes. But how did it establish, if, as is likely, earlier hominin social worlds resemble those of our close pan relatives in the suspicion (even hostility) of one band to another? How did hominin social organisation transition from life in closed bands, each distrustful of its neighbours, to the much more open social lives of foragers? I will discuss and synthesise two approaches to this problem, one ecological, based on the work of Robert Layton and his colleagues, and another that is organised around an expansion of kin recognition, an idea primarily driven by Bernard Chapais. The paper closes by discussing potential archaeological signatures both of more open social worlds, and of the supposed causal drivers of such worlds. (shrink)
