Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

Ethics training has been highlighted as essential for building and fostering business ethics in organizations. National and international trends show that over 40% of businesses have some form of business ethics training. We use data collected from 199 firms to examine the presence of ethics training in top Canadian companies and found that the presence varied by region and firm size, and that the Canadian average (35%) lags other countries.

The latest book in the Philosophy, Theory, and Educational Research series introduces the main philosophical and theoretical ideas of recent western feminisms as it applies to educational research. Unlike other books that focus on these topics, the authors present a balanced overview of the issues, instead of pushing a particular perspective.

The publication of the Fraser Institute's Discrimination, Affirmative Action, and Equal Opportunity offers an occasion to review some of the practical and philosophical issues raised by affirmative action policy. Canadian affirmative action programs derive from the American context, which is here reviewed, but do not have the legal recourse available in the American system. Perhaps as a consequence, most Canadian programs have been carried out by governments acting in their role as employers. The Canadian Union of Public Employees has been (...) especially active in developing union perspectives on affirmative action programs, which do raise special concerns for organized labour. Affirmative action raises several basic questions: the importance of proportionality, merit, compensation and role models in determining who is entitled to opportunities in our society. Differences between the Fraser Institute's attitude about affirmative action and attitudes of other social groups, such as the labour movement, lie in their very different assumptions about what constitutes a free society.

The belief that damaging an object may harm the individual to which the object relates is common among adults. We explored whether arousal following the destruction of a photograph of a loved partner is greater than that following the destruction of a photograph of a stranger, and whether this response is greater than when a photograph representing a non-person sentimental attachment is destroyed, using a measure of skin conductance response. Long-term supporters of a football team, who were also in a (...) long-term relationship, showed increased arousal when asked to destroy a photograph of their partner, but not a photograph of their team, even though both elicited equivalent ratings of emotional attachment. This may be because football teams are conceptualized differently from individuals. Future studies should address whether destruction of symbols that represent the enduring nature of the team elicit more emotional distress than photograph. (shrink)

Leveraging perspectives from social cognitive theory, the attention-based view, and social networks literatures, we tested the relationship between unethical choice and network unethicality, which we define as respondents’ perceptions of their peer advisors’ unethical choices. Although social cognitive theory predicts that perceptions of peer advisor unethical choice are positively associated with unethical choice, we theorize that the nature of this relationship depends on the personality of the actor and the situation. Results from a lagged study suggest that individual and situational (...) variables may act as key buffers to the adverse impact of unethical social influence on ethical choice. Strengths, limitations, and directions for future research are discussed. (shrink)

_An illuminating record of dialogues between the Dalai Lama and some of today’s most prominent scientists, philosophers, and contemplatives_ In 2013, during a historic six-day meeting at a Tibetan monastery in southern India, the Dalai Lama gathered with leading scientists, philosophers, and monks for in-depth discussions on the nature of reality, consciousness, and the human mind. This eye-opening book presents a record of those spirited and wide-ranging dialogues, featuring contributions from prominent scholars like Richard Davidson, Matthieu Ricard, Tania Singer, and (...) Arthur Zajonc as they address such questions as: Does nature have a nature? Do you need a brain to be conscious? Can we change our minds and brains through meditation? Throughout, the contributors explore the exciting and sometimes surprising commonalities between Western scientific and Tibetan Buddhist methods of perceiving, investigating, and knowing. Part history, part state-of-the-field, part inspiration for the future, this book rigorously and accessibly explores what these two investigative traditions can teach each other, and what that can tell us about ourselves and the world.

Social machines are a prominent focus of attention for those who work in the field of Web and Internet science. Although a number of online systems have been described as social machines, there is, as yet, little consensus as to the precise meaning of the term “social machine.” This presents a problem for the scientific study of social machines, especially when it comes to the provision of a theoretical framework that directs, informs, and explicates the scientific and engineering activities of (...) the social machine community. The present paper outlines an approach to understanding social machines that draws on recent work in the philosophy of science, especially work in so-called mechanical philosophy. This is what might be called a mechanistic view of social machines. According to this view, social machines are systems whose phenomena are explained via an appeal to socio-technical mechanisms. We show how this account is able to accommodate a number of existing attempts to define the social machine concept, thereby yielding an important opportunity for theoretical integration. (shrink)

Ocean biology helps regulate global climate by fixing atmospheric CO2 and exporting it to deep waters as sinking detrital particles. New observations demonstrate that particle fragmentation is the principal factor controlling the depth to which these particles penetrate the ocean's interior, and hence how long the constituent carbon is sequestered from the atmosphere. The underlying cause is, however, poorly understood. We speculate that small, particle‐associated copepods, which intercept and inadvertently break up sinking particles as they search for attached protistan prey, (...) are the principle agents of fragmentation in the ocean. We explore this idea using a new marine ecosystem model. Results indicate that explicitly representing particle fragmentation by copepods in biogeochemical models offers a step change in our ability to understand the future evolution of biologically‐mediated ocean carbon storage. Our findings highlight the need for improved understanding of the distribution, abundance, ecology and physiology of particle‐associated copepods. (shrink)

Genomic research—including whole genome sequencing and whole exome sequencing—has a growing presence in contemporary biomedical investigation. The capacity of sequencing techniques to generate results that go beyond the primary aims of the research—historically referred to as “incidental findings”—has generated considerable discussion as to how this information should be handled—that is, whether incidental results should be returned, and if so, which ones.Federal regulations governing most human subjects research in the United States require the disclosure of “the procedures to be followed” in (...) the research as part of the informed consent process. It seems reasonable to assume—and indeed, many commentators have concluded—that genomic investigators will be expected to inform participants about, among other procedures, the prospect that incidental findings will become available and the mechanisms for dealing with them. Investigators, most of whom will not have dealt with these issues before, will face considerable challenges in framing meaningful disclosures for research participants.To help in this task, we undertook to identify the elements that should be included in the informed consent process related to incidental findings. We did this by surveying a large number of genomic researchers (n = 241) and by conducting in‐depth interviews with a smaller number of researchers (n = 28) and genomic research participants (n = 20). Based on these findings, it seems clear to us that routine approaches to informed consent are not likely to be effective in genomic research in which the prospect of incidental findings exists. Ensuring that participants’ decisions are informed and meaningful will require innovative approaches to dealing with the consent issue. We have identified four prototypical models of a consent process for return of incidental findings. (shrink)

This case is another in a series intended to highlight the new questions emerging from advances in mapping the human genome and the application of genetic findings to clinical practice. The National Human Genome Research Institute, a component of the National Institutes of Health, by law is directed to designate a portion of its annual budget to furthering understanding of the ethical, legal, and social questions emerging from research on the human genome. As part of the effort, the Institute supports (...) research by scientists and scholars around the nation with the aim of clarifying and resolving the tough ethical and research choices facing this endeavor. But recently it has launched an intramural program, which is expected to take a catalytic role in grappling with the array of issues the researchers face in carrying out investigations in human genetics.

People diagnosed with cancer typically want information from their doctor or nurse. However, many individuals now turn to the Internet to tackle unmet information needs and to complement healthcare professional information. The purpose of this study was to qualitatively explore the content of commonly searched cancer websites from a critical nursing perspective, as this information is accessible, and allows patients to address their information needs in ways that healthcare professionals cannot. This qualitative examination of websites is informed by Carper's fundamental (...) patterns of knowing and complemented with the critical view to technology espoused by the philosophy of technology. We conducted a review of 20 websites using a two‐step interpretive descriptive approach and thematic analysis. We identified the dominant discourse to be focused on empirical information on treatment, prognosis, and cure, and a paucity of sociopolitical, ethical, personal, and esthetic information. In place of holistic, nuanced, and accurate knowledge nurses may provide, patients find predominantly empirical and biomedical information online. Discussion explores and critiques online cancer content, gaps in information, and the importance of information diversity. Implications focus on needed discourse around pervasive technologies and the nursing role in assessing and directing patients to holistic information. (shrink)

At the forefront of international concerns about global legislation and regulation, a host of noted environmentalists and business ethicists examine ethical issues in consumption from the points of view of environmental sustainability, economic development, and free enterprise.

Integrated developmental and elemental information in teeth provide a unique framework for documenting breastfeeding histories, physiological disruptions, and neurotoxicant exposure in humans and our primate relatives, including ancient hominins. Here we detail our method for detecting the consumption of mothers’ milk and exploring health history through the use of laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) mapping of sectioned nonhuman primate teeth. Calcium‐normalized barium and lead concentrations in tooth enamel and dentine may reflect milk and formula consumption with minimal modification during (...) subsequent tooth mineralization, particularly in dentine. However, skeletal resorption during severe illness, and bioavailable metals in nonmilk foods, can complicate interpretations of nursing behavior. We show that explorations of the patterning of multiple elements may aid in the distinction of these important etiologies. Targeted studies of skeletal chemistry, gastrointestinal maturation, and the dietary bioavailability of metals are needed to optimize these unique records of human health and behavior. (shrink)

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

: In “Hegel’s Phenomenological Method,” Kenley R. Dove maintains that the method of the Phenomenology of Spirit is not dialectical but instead wholly phenomenological. That is, Dove claims that Hegel’s method is purely descriptive. Dove’s interpretation has been highly influential and widely accepted. This article argues that, although there is a phenomenological aspect to Hegel’s method, that aspect itself presupposes a prior dialectical moment. Failure to account for that dialectical moment results in spirit being reduced to substance.

Research is increasingly recognised as a key component of medical curricula, offering a range of benefits including development of skills in evidence-based medicine. The literature indicates that experienced academic supervision or mentoring is important in any research activity and positively influences research output. The aim of this project was to investigate the human research ethics experiences and knowledge of three groups: medical students, and university academic staff and clinicians eligible to supervise medical student research projects; at two Australian universities. Training (...) in research ethics was low amongst academic staff and clinicians eligible to supervise medical student research. Only two-thirds of academic staff and students and less than half of clinicians surveyed indicated that specific patient consent was required for a doctor to include patient medical records within a research publication. There was limited awareness of requirements for participant information and consent forms amongst all groups. In the case of clinical trials, fewer clinicians and students than academics indicated there was a requirement to obtain consent. Awareness of the ethics committee focus on respect was low across all groups. This project has identified significant gaps in human research ethics understanding among medical students, and university academic staff and clinicians. The incorporation of research within medical curricula provides the impetus for medical schools and their institutions to ensure that academic staff and clinicians who are eligible and qualified to supervise students’ research projects are appropriately trained in human research ethics.

The mammalian chromosome is longitudinally heterogeneous in structure and function and this is the basis for the specific banding patterns produced by various chromosome staining techniques. The two most frequently used techniques are G, or Giemsa banding and R, or reverse banding. Each type of stained band is characterised by variations in gene density, time of replication, base composition, density of repeat sequences, and chromatin packaging. It is increasingly apparent that R and G bands, which are complementary to each other, (...) represent separate compartments of the euchromatic human genome, with R bands containing the vast majority of genes. R bands are also more GC‐rich, contain a higher density of Alu repeats, and replicate earlier in S phase, than G bands. These properties may be interdependent and may have coevolved. (shrink)

This is the long-awaited publication of a set of writings by the British philosopher, historian, and archaeologist R.G. Collingwood on critical, anthropological, and cultural themes only hinted at in his previously available work. At the core are six essays on folktale and magic in which Collingwood applies the principles of his philosophy of history to problems in the long-term evolution of human society and culture. The volume opens with three substantial introductory essays by the editors, authorities in their various fields, (...) who provide their explanatory and contextual notes to guide the reader through the texts. The Philosophy of Enchantment highlights the broad range of Collingwood's intellectual engagements, their integration, and their relevance to current areas of debate in the fields of philosophy, cultural studies, social and literary history, and anthropology.

Background In Switzerland, right-to-die organisations assist their members with suicide by lethal drugs, usually barbiturates. One organisation, Dignitas, has experimented with oxygen deprivation as an alternative to sodium pentobarbital. Objective To analyse the process of assisted suicide by oxygen deprivation with helium and a common face mask and reservoir bag. Method This study examined four cases of assisted suicide by oxygen deprivation using helium delivered via a face mask. Videos of the deaths were provided by the Zurich police. Dignitas provided (...) protocol and consent information. Results One man and three women were assisted to death by oxygen deprivation. There was wide variation in the time to unconsciousness and the time to death, probably due to the poor mask fit. Swiss law prevented attendants from effectively managing the face mask apparatus. Purposeless movements of the extremities were disconcerting for Dignitas attendants, who are accustomed to assisting suicide with barbiturates. None of the dying individuals attempted self-rescue. Conclusions The dying process of oxygen deprivation with helium is potentially quick and appears painless. It also bypasses the prescribing role of physicians, effectively demedicalising assisted suicide. Oxygen deprivation with a face mask is not acceptable because leaks are difficult to control and it may not eliminate rebreathing. These factors will extend time to unconsciousness and time to death. A hood method could reduce the problem of mask fit. With a hood, a flow rate of helium sufficient to provide continuous washout of expired gases would remedy problems observed with the mask. (shrink)
