Despite its importance, the linkage between genetic and cultural evolution has until now been little explored. An understanding of this linkage is needed to extend evolutionary theory so that it can deal for the first time with the phenomena of mind and human social history. We characterize the process of gene-culture coevolution, in which culture is shaped by biological imperatives while biological traits are simultaneously altered by genetic evolution in response to cultural history. A case is made from both theory (...) and evidence that genetic and cultural evolution are inseverable, and that the human mind has tended to evolve so as to bias individuals toward certain patterns of cognition and choice rather than others. With the aid of mathematical models we trace the coevolutionary circuit: The genes prescribe structure in developmental pathways that lay down endocrine and neural systems, imposing regularities in the development of cognition and behavior; these regularities translate upward into holistic patterns of culture, which can be predicted in the form of probability density distributions ; natural selection acts within human history to favor certain epigenetic rules over others; and the selection alters the frequencies of the underlying genes. The effects of genetic and cultural changes reverberate throughout the circuit and are consequently tested with the passage of each life cycle. In addition to modeling gene-culture coevolution, we apply methods from island biogeography and information theory to examine the cultural capacity of the genes, the factors determining the magnitude of cultural diversity, and the possible reasons for the uniqueness of the human achievement.

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 Essay examines the elegantly simple idea that consent to medical treatment or participation in human research must be “informed” to be valid. It does so by using as a case study the controversial clinical research trial known as the Surfactant, Positive Pressure, and Oxygenation Randomized Trial. The Essay begins by charting, through case law and the adoption of the common rule, the evolution of duties to secure fully informed consent in both research and treatment. The Essay then utilizes the (...) SUPPORT study, which sought to pinpoint the level of saturated oxygen that should be provided to extremely low birth weight infants to demonstrate modern complexities and shortcomings of the duty to secure informed consent. This Essay shows how the duty is measured by foreseeability of risks and benefits in human research and why federal regulators believed the tradeoffs in risk and benefits from differing oxygen levels administered in the support study were foreseeable. It then explores the contours of the duty to secure informed consent when applied to researchers who also serve as treating physicians, highlighting how common law duties differ in jurisdictions that apply the professional standard and those that apply the patient-centered material risk standard. This Essay provides new insight into what the law must do to make real the notion that [e]very human being of adult years and sound mind has a right to determine what shall be done with his body.”.

Originally published in 1973 the editors of this book collected together those studies which had been considered at the time to yield the best evidence in support of Freudian theory, and found on close examination that they failed to provide any such proof. Each paper is printed in full and is followed by a critical discussion which raises questions of statistical treatment, sufficiency of controls and alternative interpretations. The particular usefulness of this format is that it allows readers to form (...) their own opinions while providing helpful suggestions and guidelines on how to approach experimental studies with a critical mind.

A far-reaching and influential view in evolutionary biology claims that species are cohesive units held together by gene flow. Biologists have recognized empirical problems facing this view; after sharpening the expression of the view, we present novel conceptual problems for it. At the heart of these problems is a distinction between two importantly different concepts of cohesion, what we call integrative and response cohesion. Acknowledging the distinction problematizes both the explanandum of species cohesion and the explanans of gene flow that (...) are central to the view we discuss. We conclude by tracing four broader implications for the study and conceptualization of species. (shrink)

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

Enhancer detectors are DNA constructs which, when introduced into a eukaryotic genome, respond to nearby genomic transcriptional regulatory elements by means of a reporter gene, revealing the expression pattern of genes in their vicinity. Recent experiments in Drosophila suggest that enhancer detection is a powerful method to identify genes that are expressed in the nervous system. Since enhancer detectors allow a rapid molecular and genetic characterization of genes in their vicinity, the method will greatly facilitate the study of neural development (...) and behavior.

In response to its current crisis, scholars call for the revitalisation of democracy through democratic innovations. While they make ample use of life metaphors describing democracy as a living organism, no comprehensive understanding of ‘life’ has been established within democratic theory. The Black Lives Matter (BLM) movement articulates the urgency of refocusing on life and its meaning through radical democratic practice. This article employs a grounded theory approach, enriched with participatory methods, to develop a radical democratic concept of life in (...) conversation with BLM. It conceptualises life as the existence of a perspective that constantly transforms through its fundamental interconnectedness. Building on this concept, the article outlines four principles of a living democracy that go beyond the revitalisation discourse. A living democracy (1) safeguards the existence of all humans and nonhumans, (2) nurtures a diversity of perspectives, (3) fosters social and planetary connectivity, and (4) enables self- and collective transformation.

Most academic papers on ethics in pandemics concentrate on the duties of healthcare professionals. This paper will consider non-professional healthcare workers: do they have a moral obligation to work during an influenza pandemic? If so, is this an obligation that outweighs others they might have, e.g., as parents, and should such an obligation be backed up by the coercive power of law? This paper considers whether non-professional healthcare workers—porters, domestic service workers, catering staff, clerks, IT support workers, etc.—have an obligation (...) to work during an influenza pandemic. It uses data collected as part of a study looking at the attitudes of healthcare workers to working during a pandemic to suggest the philosophical arguments explored. These include: being in a position to do good, the ethics of work, competing obligations to family members and in particular to children and the obligations of citizens in a state of national emergency. We also look at whether compulsory measures are justified to support a national health service during a health emergency. We conclude that even if they are, compulsion should not be restricted to non-professionals who happen to be working in the health service at the time. Rather, compulsion involving a larger pool of people with the relevant skills and abilities is more equitable. (shrink)

The objective of the study was to investigate the relationship between childhood IQ of parents and characteristics of their adult offspring. It was a prospective family cohort study linked to a mental ability survey of the parents and set in Renfrew and Paisley in Scotland. Participants were 1921-born men and women who took part in the Scottish Mental Survey in 1932 and the Renfrew/Paisley study in the 1970s, and whose offspring took part in the Midspan Family study in 1996. There (...) were 286 offspring from 179 families. Parental IQ was related to some, but not all characteristics of offspring. Greater parental IQ was associated with taller offspring. Parental IQ was inversely related to number of cigarettes smoked by offspring. Higher parental IQ was associated with better education, offspring social class and offspring deprivation category. There were no significant relationships between parental IQ and offspring systolic blood pressure, diastolic blood pressure, cholesterol, glucose, lung function, weight, body mass index, waist hip ratio, housing, alcohol consumption, marital status, car use and exercise. Structural equation modelling showed parental IQ associated with offspring education directly and mediated via parental social class. Offspring education was associated with offspring smoking and social class. The smoking finding may have implications for targeting of health education. (shrink)

As the term regenerative agriculture caught fire in public discourse around 2019, it was promptly labelled a buzzword. While the buzzword accusation tends to be regarded as negative, these widely used terms also reflect an important area of growing public interest. Exploring a buzzword can thus help us understand our current moment and offer insights to paths forward. In this study, we explored how and why different individuals and groups adopt certain key terms or buzzwords, in this case the term (...) “regenerative agriculture”. We used an interpretivist approach to understand how “regenerative agriculture” is being constructed, interpreted, understood, and employed, drawing from 19 semi-structured interviews conducted with farmers, researchers, private companies, and NGO/nonprofits. Several interviewees felt that regenerative agriculture is making an important societal shift in thinking towards addressing major issues like climate change and parity in our food and agricultural systems. However, farmers in particular felt that the term is being greenwashed, coopting the work they do, and even diluting the meaning. We also found that regenerative agriculture is being advanced as mobilizing “win-wins”—for farmers, for consumers, for society—but that this discourse may be veiling the political and economic agendas of the big companies using the term. Our findings further illustrated the debates over standardizing the term regenerative agriculture, with some contending that there should be room for “continuous improvement” but others felt it is meaningless without a definition.

Modeling and computer simulations, we claim, should be considered core philosophical methods. More precisely, we will defend two theses. First, philosophers should use simulations for many of the same reasons we currently use thought experiments. In fact, simulations are superior to thought experiments in achieving some philosophical goals. Second, devising and coding computational models instill good philosophical habits of mind. Throughout the paper, we respond to the often implicit objection that computer modeling is “not philosophical.”.

Academic integrity is one of the significant issues facing assessments in higher education. While there are a plethora of papers addressing this problem in certain locales, very little research has been published regarding tertiary institutions in the Caribbean. This paper satisfies this paucity in the literature and present findings which will help benchmark it against other comparable populations. This mixed-methods case study examines first-year students’ perceptions of plagiarism definitions, its seriousness, reasons for plagiarising, and its prevalence in a General Chemistry (...) lab course at a Jamaican university. Quantitative and qualitative data were collected and triangulated using a questionnaire and document analysis to understand the complexity of participants’ views. The results show that students largely define plagiarism as copying portions of text and not citing someone else’s work. While accepting that copying large and small portions of text are serious offences, students are less inclined to perceive copying a picture and self-plagiarism as problematic. Although students believe plagiarism is prevalent, they oppose harsh consequences, citing lack of understanding, course difficulty, time management issues, lack of motivation, and fear of failure as understandable reasons. Institutional recommendations to mitigate this growing concern include implementing strategies that would broaden students’ knowledge of what constitutes plagiarism, employing pedagogic strategies that aim to increase students’ self-efficacy, creating a more supportive academic environment, and reducing participation in plagiaristic behaviour.
