The subjective effects and therapeutic potential of the shamanic practice of journeying is well known. However, previous research has neglected to provide a comprehensive assessment of the subjective effects of shamanic-like journeying techniques on non-shamans. Shamanic-like techniques are those that demonstrate some similarity to shamanic practices and yet deviate from what may genuinely be considered shamanism. Furthermore, the personality traits that influence individual susceptibility to shamanic-like techniques are unclear. The aim of the present study was, thus, to investigate experimentally the (...) effect of shamanic-like techniques and a personality trait referred to as "ego boundaries" on subjective experience including mood disturbance. Forty-three non-shamans were administered a composite questionnaire consisting of demographic items and a measure of ego boundaries (i.e., the Short Boundary Questionnaire; BQ-Sh). Participants were randomly assigned to one of three conditions: listening to monotonous drumming for 15 minutes coupled with one of two sets of journeying instructions; or sitting quietly with eyes closed for 15 minutes. Participants' subjective experience and mood disturbance were retrospectively assessed using the Phenomenology of Consciousness Inventory (PCI) and the Profile of Mood States-Short Form, respectively. The results indicated that there was a statistically significant difference between conditions with regard to the PCI major dimensions of visual imagery, attention and rationality, and minor dimensions of imagery amount and absorption. However, the shamanic-like conditions were not associated with a major reorganization of the pattern of subjective experience compared to the sitting quietly condition, suggesting that what is typically referred to as an altered state of consciousness effect was not evident. One shamanic-like condition and the BQ-Sh subscales need for order, childlikeness, and sensitivity were statistically significant predictors of total mood disturbance. Implications of the findings for the anthropology of consciousness are also considered. (shrink)

This article discusses five attempts at justifying the provision of welfare on Kantian grounds. I argue that none of the five proposals is satisfactory. Each faces a serious challenge on textual or systematic grounds. The conclusion to draw from this is not that a Kantian cannot defend the provision of welfare. Rather, the conclusion to draw is that the task of defending the provision of welfare on Kantian grounds is a difficult one whose success we should not take for granted.

Recent research on the evolution of religion has focused on whether religion is an unselected by-product of evolutionary processes or if it is instead an adaptation by natural selection. Adaptive hypotheses for religion include direct fitness benefits from improved health and indirect fitness benefits mediated by costly signals and/or cultural group selection. Herein, I propose that religious denominations achieve indirect fitness gains for members through the use of ecologically arbitrary beliefs, rituals, and moral rules that function as recognition markers of (...) cultural inheritance analogous to kin and species recognition of genetic inheritance in biology. This recognition signal hypotheses could act in concert with either costly signaling or cultural group selection to produce evolutionarily altruistic behaviors within denominations. Using a cultural phylogenetic analysis, I show that a large set of religious behaviors among extant Christian denominations supports the prediction of the recognition signal hypothesis that characters change more frequently near historical schisms. By incorporating demographic data into the model, I show that more-distinctive denominations, as measured through dissimilar characteristics, appear to be protected from intrusion by nonmembers in mixed-denomination households, and that they may be experiencing greater biological growth of their populations even in the present day.

This book explores both scientific and humanistic theoretical traditions in anthropology through the lens of ontology. The first part of the book examines different methods for generating valid anthropological knowledge, and proposes a shift in current consensus. Drawing on western scholars of antiquity and the medieval period and moving away from twentieth century theorists, it argues that we must first make ontological assumptions about the kinds of things that can exist (or not) before we can then develop epistemologies that study (...) those kinds of things. The book goes on to apply the ontology-first theory to a set of case studies in modern day conspiracy theories, misinformation, and magical thinking. It asserts that we need to move away from unneeded metaphysical assumptions of conspiracy theories being misinformation, and argues that reconstructing particular historical events can be a fruitful zone for application of quantitative methods to humanistic questions. Theorizing the Anthropology of Belief is an excellent supplementary suitable for upper-level undergraduate and graduate courses in anthropological theory. (shrink)

Finitary sketches, i.e., sketches with finite-limit and finite-colimit specifications, are proved to be as strong as geometric sketches, i.e., sketches with finite-limit and arbitrary colimit specifications. Categories sketchable by such sketches are fully characterized in the infinitary first-order logic: they are axiomatizable by σ-coherent theories, i.e., basic theories using finite conjunctions, countable disjunctions, and finite quantifications. The latter result is absolute; the equivalence of geometric and finitary sketches requires (in fact, is equivalent to) the non-existence of measurable cardinals.

In rebellion against low‐dimensional (e.g., two‐factor) theories in psychology, the authors make the case for high‐dimensional theories. This change in perspective requires a shift towards a focus on computation and quantitative reasoning.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

When people engage in conversation, they tailor their utterances to their conversational partners, whether these partners are other humans or computational systems. This tailoring, or adaptation to the partner takes place in all facets of human language use, and is based on a mental model or a user model of the conversational partner. Such adaptation has been shown to improve listeners' comprehension, their satisfaction with an interactive system, the efficiency with which they execute conversational tasks, and the likelihood of achieving (...) higher level goals such as changing the listener's beliefs and attitudes. We focus on one aspect of adaptation, namely the tailoring of the content of dialogue system utterances for the higher level processes of persuasion, argumentation and advice-giving. Our hypothesis is that algorithms that adapt content for these processes, according to a user model, will improve the usability, efficiency, and effectiveness of dialogue systems. We describe a multimodal dialogue system and algorithms for adaptive content selection based on multi-attribute decision theory. We demonstrate experimentally the improved efficacy of system responses through the use of user models to both tailor the content of system utterances and to manipulate their conciseness. (shrink)

Colorado has consistently had one of the highest rates of suicide in the United States, and El Paso County has the highest number of suicide and firearm-related suicide deaths within the state. Community-based solutions like those of the Suicide Prevention Collaborative of El Paso County may be more effective in preventing suicide as they are specific to local issues, sensitive to local culture, and informed by local data, community members, and stakeholders.

Contemporary approaches to adolescent development are framed by positive youth development models. A key outcome of these models is that healthy and positively developing youth are more likely to contribute to their family, schools, and communities. However, little work on contribution and its antecedents has been conducted with youth of color. As high achieving youth of color often become leaders in their communities, it is important to consider malleable predictors of contribution within this population. Therefore, through a cross-sectional design, we (...) examined the relations between youth critical reflection, hopeful future expectations, and mentoring relationship quality and youth contribution in a sample of 177 youth of color (60% Black, 40% Latinx) attending an afterschool college preparation program at six sites around the U.S. Results indicated that youth critical reflection, hopeful future expectations, and mentoring relationship quality significantly predicted contribution. Exploratory analyses suggested that these relations were significant for Black youth but not Latinx youth. Implications of these findings for future scholarship are discussed. (shrink)

Community gardens are of increasing interest to scholars, policymakers, and community organizations but there has been little systematic study of community garden management at a broad scale. This study complements case study research by revealing shared experiences of community garden management across different contexts. In partnership with the American Community Gardening Association, we developed an online questionnaire. Results from 445 community garden organizations across the US and Canada reveal common themes as well as differences that are particularly significant across different (...) organizational sizes. The findings suggest that organizers see multiple benefits, and respondents confirmed recent expansion of gardening efforts. Analysis then focuses on challenges, which are closely related to garden management. We address garden losses as well as challenges to routine operation. Key challenges included funding, participation, land, and materials. We developed a typology based on organization size, to reveal distinctions between small organizations (serving 1 garden), medium-sized organizations (2–3 gardens), large organizations (4–30 gardens) and very large organizations (31 or more gardens). These categories shed light on different needs for funding, land, material, and participation. Together, this analysis suggests that community gardens can be linked through the work it takes to sustain them rather than specific causes or outcomes. Community gardens can be better integrated into local food systems through analysis of how people involved with this work navigate these shared processes. (shrink)

Interest in science and math plays an important role in encouraging STEM motivation and career aspirations. This interest decreases for girls between late childhood and adolescence. Relatedly, positive mentoring experiences with female teachers can protect girls against losing interest. The present study examines whether visitors to informal science learning sites differ in their expressed science and math interest, as well as their science and math stereotypes following an interaction with either a male or female educator. Participants were visitors to one (...) of four ISLS in the United States and United Kingdom. Following an interaction with a male or female educator, they reported their math and science interest and responded to math and science gender stereotype measures. Female participants reported greater interest in math following an interaction with a female educator, compared to when they interacted with a male educator. In turn, female participants who interacted with a female educator were less likely to report male-biased math gender stereotypes. Self-reported science interest did not differ as a function of educator gender. Together these findings suggest that, when aiming to encourage STEM interest and challenge gender stereotypes in informal settings, we must consider the importance of the gender of educators and learners.

Medical tourism is a practice, whereby individuals travel across national borders with the intention of receiving medical care. Medical tourists are motivated to travel abroad by a number of factors, including the affordability of care abroad, access to treatments not available at home, and wait times for care at home. In this article, we share the findings of interviews conducted with 32 Canadian medical tourists with the aim of developing a better understanding of medical tourism, the ethical issues it raises (...) for public health within Canada and other source countries for medical tourists, and to identify research gaps and policy responses to this practice. While patient and academic perspectives overlap in several regards, we suggest areas in which academic consideration of the ethical issues raised by medical tourism can be informed by patient perspectives.

Background: Medical tourism involves patients travelling internationally to receive medical services. This practice raises a range of ethical issues, including potential harms to the patient's home and destination country and risks to the patient's own health. Medical tourists often engage the services of a facilitator who may book travel and accommodation and link the patient with a hospital abroad. Facilitators have the potential to exacerbate or mitigate the ethical concerns associated with medical tourism, but their roles are poorly understood. -/- (...) Methods: 12 facilitators were interviewed from 10 Canadian medical tourism companies. -/- Results: Three themes were identified: facilitators' roles towards the patient, health system and medical tourism industry. Facilitators' roles towards the patient were typically described in terms of advocacy and the provision of information, but limited by facilitators' legal liability. Facilitators felt they played a positive role in the lives of their patients and the Canadian health system and served as catalysts for reform, although they noted an adversarial relationship with some Canadian physicians. Many facilitators described personally visiting medical tourism sites and forming personal relationships with surgeons abroad, but noted the need for greater regulation of their industry. -/- Conclusion: Facilitators play a substantial and evolving role in the practice of medical tourism and may be entering a period of professionalisation. Because of the key role of facilitators in determining the effects of medical tourism on patients and public health, this paper recommends a planned conversation between medical tourism stakeholders to define and shape facilitators' roles.

The Mental Capacity Act received Royal Assent on 7 April 2005, and it will be implemented in 2007. The Act defines when someone lacks capacity and it supports people with limited decision-making ability to make as many decisions as possible for themselves. The Act lays down rules for substitute decision making. Someone taking decisions on behalf of the person lacking capacity must act in the best interests of the person concerned and choose the options least restrictive of his or her (...) rights and freedoms. Decision making will be allowed without any formal procedure unless specific provisions apply, such as a written advance decision, lasting powers of attorney or a decision by the court of protection.

Automated vehicles promise much in the way of both economic boons and increased personal safety. For better or worse, the effects of automating personal vehicles will not be felt for some time. In contrast, the effects of automated work vehicles, like semi-trucks, will be felt much sooner—within the next decade. The costs and benefits of automation will not be distributed evenly; while most of us will be positively affected by the lower prices overall, those losing their livelihoods to the automated (...) semi-trucks and other similar work vehicles will be much worse off. This sets up a classic distributive justice problem: how do we balance the harms and benefits of automation? In this paper, the authors recommend work alternatives: policies that the government would enact in order to ensure that each person could live a decent life even if one could not work, especially for reasons like having one’s job automated. After arguing for this position, we propose some policy guidelines. (shrink)

Organizations that believe they should "give something back" to the society have embraced the concept of corporate social responsibility (CSR). Although the theoretical underpinnings of CSR have been frequently debated, empirical studies often involve only limited aspects, implying that theory may not be congruent with actual practices and may impede understanding and further development of CSR. The authors investigate actual CSR practices related to five different stakeholder groups, develop an instrument to measure those CSR practices, and apply it to a (...) survey of 401 U.S. organizations. Four different clusters of organizations emerge, depending on the CSR practice focus. The distinctive features of each cluster relate to organizational demographics, perceived influence of stakeholders, managers' perceptions of the influence of CSR on performance, and organizational performance.

Folie à deux is the transference of delusional ideas from one 'primary' individual to one or more 'secondary' individuals (Lasègue & Falret, 1877). However, it is difficult to investigate experimentally because often only one patient is identified as delusional. We investigated whether hypnosis could model the experiences of the secondary in this delusion. Our primary was a confederate, who displayed two delusional beliefs and attempted to transmit them to hypnotised subjects. We manipulated the status of the confederate so that they (...) were portrayed as either "credible" or merely "interesting". Many high hypnotisable individuals adopted the confederate's beliefs and confabulated evidence in support of them. Also, subjects who interacted with a credible confederate extended their delusions beyond those displayed by the confederate. We discuss the strengths and limitations of this approach and suggest ways to improve the validity of this model. (shrink)

This book holds classical liberalism responsible for an American concept of beauty that centers upon women, wilderness, and machines. For each of the three beauty components, a cultural entrepreneur supremely sensitive to liberalism’s survival agenda is introduced. P.T. Barnum’s exhibition of Jenny Lind is a masterful combination of female elegance and female potency in the subsistence realm. John Muir’s Yosemite Valley is surely exquisite, but only after a rigorous liberal education prepares for its experience. And Harley Earl’s 1955 Chevrolet Bel (...) Air is a dreamy expressionist sculpture, but with a practical 265 cubic inch V-8 underneath. Not that American beauty has been uniformly pragmatic. The 1950s are reconsidered for having temporarily facilitated a relaxation of the liberal survival priorities, and the creations of painter Jackson Pollock and jazz virtuoso Ornette Coleman are evaluated for their resistance to the pressures of pragmatism. The author concludes with a provocative speculation regarding a future liberal habitat where Emerson’s admonition to attach stars to wagons is rescinded. (shrink)
