Two groups of scientists have just announced what is being described as a leap forward in human stem cell research.1–3 Both have found ways of producing what are being called “induced pluripotent cells” , stem cells that they hope will demonstrate the same key properties of regeneration and unrestricted differentiation that human embryonic stem cells possess, but which are derived from skin cells not from embryos. In simple terms, these scientists have succeeded in reprogramming skin cells to behave like hESCs.Stem (...) cell research has been hailed as one of the most important and exciting areas of science, because it is believed that these types of cells will not only play an important part in regenerative medicine, but also yield valuable scientific information. These latest developments in cell reprogramming represent a milestone for stem cell science. No longer does the paradigm of irreversible cell specialisation hold true; instead, almost any type of cell might have the potential to become any other.The advent of techniques for producing these iPCs has also been hailed as an ethical breakthrough. Up until now, the production of hESCs has required a process which involves the destruction of embryos. Many of these embryos are available as by-products of IVF; but in addition, the process of somatic cell nuclear transfer to produce cloned embryonic stem cells requires a supply of human oocytes, which must currently be harvested from female donors at no insignificant cost. In a nutshell, iPCs seem to enable us to produce “embryo-free” human pluripotent stem cells, and in a “gender-neutral” way—that is, without the need for human oocytes.The response from the scientific community, ethical commentators and the public has, however, reflected an inherent confusion over the ethical significance of this research. The anti-embryo …. (shrink)

New UK consensus statement on core curriculum in medical ethics and lawThe most important paper in this month’s JME is not a standard paper but the new UK consensus statement on the core curriculum in medical ethics and law for medical students. The first consensus statement was published in the JME in 1998 and has been instrumental in ensuring the embedding of a common standard of teaching in these subjects across UK medical schools. 1 However, even the most hard core (...) moral realist has to accept that, even if the fundamental principles of ethics do not change, the best way to teach it might evolve and the problems of most interest may change as the healthcare system changes. The core curriculum can therefore not be cast in stone and must be revised and updated from time to time. The current revision is the result of an extensive process involving reviews of the way ….

Questions about how to negotiate belief and non-belief in social and public spheres are attracting an increasing amount of attention from academics in a range of disciplines, and from concerned members of the public. This volume addresses the emergence of ‘new atheism’ and the developing ‘spiritual but not religious’ phenomenon. Avoiding simplistic accounts of atheism, and of religious belief, it provides readers with insight into a wide range of nuances within theism and a-theism, as well as spiritual practice and faith. (...) The chapters by an international panel of contributors focus on topics such as: a typology or cartography of atheisms and agnosticism; contrasting types of atheism within Christianity and Buddhism; questions about cognitive and doxastic stances in atheisms; theist rejections of and atheist embracing of ‘God’; atheist aesthetics. Reaching beyond the Christian tradition, the book will be of particular interest to scholars of the philosophy of religion, as well as religious studies and theology more generally. (shrink)

Dandruff is a common scalp condition, which frequently causes psychological distress in those affected. Dandruff is considered to be caused by an interplay of several factors. However, the pathogenesis of dandruff remains under‐investigated, especially with respect to the contribution of the hair follicle. As the hair follicle exhibits unique immune‐modulatory properties, including the creation of an immunoinhibitory, immune‐privileged milieu, we propose a novel hypothesis taking into account the role of the hair follicle. We hypothesize that the changes and imbalance of (...) yeast and bacterial species, along with increasing proinflammatory sebum by‐products, leads to the activation of immune response and inflammation. Hair follicle keratinocytes may then detect these changes in scalp microbiota resulting in the recruitment of leukocytes to the inflammation site. These changes in the scalp skin immune‐microenvironment may impact hair follicle immune privilege status, which opens new avenues into exploring the role of the hair follicle in dandruff pathogenesis.

So far the "Science Wars" have generated far more heat than light. Combatants from one or the other of what C. P. Snow famously called "the two cultures" (science versus the arts and humanities) have launched bitter attacks but have seldom engaged in constructive dialogue about the central issues. In The One Culture?, Jay A. Labinger and Harry Collins have gathered together some of the world's foremost scientists and sociologists of science to exchange opinions and ideas rather than insults. The (...) contributors find surprising areas of broad agreement in a genuine conversation about science, its legitimacy and authority as a means of understanding the world, and whether science studies undermines the practice and findings of science and scientists. The One Culture? is organized into three parts. The first consists of position papers written by scientists and sociologists of science, which were distributed to all the participants. The second presents commentaries on these papers, drawing out and discussing their central themes and arguments. In the third section, participants respond to these critiques, offering defenses, clarifications, and modifications of their positions. Who can legitimately speak about science? What is the proper role of scientific knowledge? How should scientists interact with the rest of society in decision making? Because science occupies such a central position in the world today, such questions are vitally important. Although there are no simple solutions, The One Culture? does show the reader exactly what is at stake in the Science Wars, and provides a valuable framework for how to go about seeking the answers we so urgently need. Contributors include: Constance K. Barsky, Jean Bricmont, Harry Collins, Peter Dear, Jane Gregory, Jay A. Labinger, Michael Lynch, N. David Mermin, Steve Miller, Trevor Pinch, Peter R. Saulson, Steven Shapin, Alan Sokal, Steven Weinberg, Kenneth G. Wilson. (shrink)

In six experiments, we investigated the role of resource valence in intergenerational attitudes and allocations. We found that, compared to benefits, allocating burdens intergenerationally increased concern with one’s legacy, heightened ethical concerns, intensified moral emotions (e.g., guilt, shame), and led to feelings of greater responsibility for and affinity with future generations. We argue that, because of greater concern with legacies and the associated moral implications of one’s decisions, allocating burdens leads to greater intergenerational generosity as compared to benefits. Our data (...) provide support for this effect across a range of contexts. Our results also indicate that the differential effect of benefits versus burdens in intergenerational contexts depends on the presence of two important structural characteristics that help enact concerns about legacies, including (1) future impact of decisions, and (2) a self-other tradeoff. Overall, our findings highlight how considering resource valence brings to the fore a number of key psychological characteristics of intergenerational decisions—especially as they relate to legacies and ethics.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Emphasis in business ethics texts and courses has generally focused on corporate and other relatively high-level ethical issues. However, business school graduates in early career stages report ethical dilemmas involving individual-level decisions, often including influence attempts from one or more members of their work role sets. This paper proposes the use of role set analysis as a pedagogical technique for helping individuals to anticipate and deal with early-career ethical issues.

The composition of nitrogen-doped hydrogenated amorphous carbon films grown in a magnetically confined rf plasma-enhanced chemical vapour deposition system has been determined by X-ray photoelectron spectroscopy and compared with that determined using a combination of elastic recoil detection analysis, Rutherford back-scattering and nuclear reaction analysis. The importance of nitrogen doping or 'incorporation' in hydrogenated amorphous carbon films is discussed in relation to the significant variation in the sp 2 -to-sp 3 ratio that takes place. At 7 at.% N in the (...) a-C : H matrix, a critical change in the microstructure is observed, which governs the resulting mechanical, optical and electronic properties. Finally, the correlation between the sp 2 and sp 3 fractions determined by a non-destructive method of obtaining the bond fractions and by electron-energy-loss spectroscopy is discussed, with a view to evaluating accurately the sp 2 fraction in a-C : H : N films.

Background: While religious faith remains one of the most significant features of human life, little is known about its relationship to ordinary belief at the level of the brain. Nor is it known whether religious believers and nonbelievers differ in how they evaluate statements of fact. Our lab previously has used functional neuroimaging to study belief as a general mode of cognition, and others have looked specifically at religious belief. However, no research has compared these two states of mind directly. (...) Methodology/Principal Findings: We used functional magnetic resonance imaging to measure signal changes in the brains of thirty subjects - fifteen committed Christians and fifteen nonbelievers - as they evaluated the truth and falsity of religious and nonreligious propositions. For both groups, and in both categories of stimuli, belief was associated with greater signal in the ventromedial prefrontal cortex, an area important for self-representation, emotional associations, reward, and goal-driven behavior. This region showed greater signal whether subjects believed statements about God, the Virgin Birth, etc. or statements about ordinary facts. A comparison of both stimulus categories suggests that religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict, while thinking about ordinary facts is more reliant upon memory retrieval networks. Conclusions/Significance: While religious and nonreligious thinking differentially engage broad regions of the frontal, parietal, and medial temporal lobes, the difference between belief and disbelief appears to be content-independent. Our study compares religious thinking with ordinary cognition and, as such, constitutes a step toward developing a neuropsychology of religion. However, these findings may also further our understanding of how the brain accepts statements of all kinds to be valid descriptions of the world. © 2009 Harris et al. (shrink)

This study examined audience perceptions of a political candidate’s credibility and likeability as a function of varying the candidate’s responses to an opponent’s nonverbal disparagement during a televised debate. 412 participants watched a purported televised debate between candidates for mayor in a small city in Utah. In all six versions, one debater engaged in strong nonverbal disagreement during his opponent’s opening statement. His opponent responded to the nonverbal behavior with one of six decreasingly polite messages. Results indicated that more direct (...) messages increased audience perceptions of the speaker’s expertise and character compared to providing no response. The results also showed a significant interaction between response type and audience member’s level of trait verbal aggressiveness. The “indirect” and “on-record with redress” responses led to stronger perceptions of speaker composure and extroversion for members high in verbal aggression and the “off the record” strategy led to higher perceptions of extroversion and composure for members low in verbal aggression.

Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predomi- nantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase ‘paradigm shift’ in (...) his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and col- leagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the man- agement of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples’ dogma makes his contribution truly a genuine paradigm shift.

If someone commits the mereological fallacy, then he ascribes psychological predicates to parts of an animal that apply only to the (behaving) animal as a whole. This incoherence is not strictly speaking a fallacy, i.e. an invalid argument, since it is not an argument but an illicit predication. However, it leads to invalid inferences and arguments, and so can loosely be called a fallacy. However, discussions of this particular illicit predication, the mereological fallacy, show that it is often misunderstood. Many (...) misunderstandings concern the use of this illicit predication in the course of discussions of understanding the mind/body problem. Our aim here is to provide an accessible overview through discussing common misconceptions of the fallacy. We also discuss how conceptual investigations of the relation between living organisms and their parts fit within the framework of modern evolutionary theory, i.e. inclusive fitness theory. (shrink)

In 1975 the Clarendon Press at Oxford published Peter Nidditch's edition of John Locke's An Essay concerning Human Understanding. In his Introduction Nidditch says that his edition “offers a text that is directly derived, without modernization, from the early published versions; it notes the provenance of all its adopted readings ; and it aims at recording all relevant differences between these versions”. As Nidditch goes on to acknowledge, the “relevant differences” were many, “requiring several thousand registrations both in the case (...) of material variants and in the case of formal variants ”. The textual history of Locke's Essay is extremely complicated. While there is no manuscript of the first edition of the book, there were four editions in Locke's lifetime, each new one containing extensive and significant revisions, as well as a posthumous edition published shortly after the author's death. There was a translation into French made with Locke's cooperation and published in 1700, and a Latin translation came out a year later. Nevertheless, Nidditch managed to record all the material variants in footnotes to the text, in a way that makes it fairly easy to track the changes that Locke made to successive editions of the book, and to locate points at which judgements had to be made as a critical text was established on the basis of the chosen copy text. Sometimes a critical edition succeeds in completely changing the way that a text is read. Peter Laslett's 1960 edition of Locke's Two Treatises of Government is a good example. Nidditch's edition of the Essay did not have that kind of very dramatic effect on Locke scholarship. Rather, it made it possible for those without direct access to all the early editions to engage in careful, historically sensitive studies of Locke's account of human understanding. The result was a slow revolution in Locke studies that continues to shed new light on even the most familiar aspects of the Lockean philosophy. (shrink)

In this paper I consider the context and significance of the first instalment of Hume's A Treatise of Human Nature , Books One and Two, on the understanding and on the passions, published in 1739 without Book Three. I argue that Books One and Two taken together should be read as addressing the question of the relation between reason and passion, and place Hume's discussion in the context of a large early modern philosophical literature on the topic. Hume's goal is (...) to show that the passions do not require government by reason, and to illustrate various ways in which the passions of social beings regulate themselves. The underlying theme of the first Treatise is thus a new theory of sociability: sympathetic sociability. (shrink)

Physician-written “do not resuscitate” DNR orders elicit negative reactions from stakeholders that may decrease appropriate end-of-life care. The semantic significance of the phrase has led to a proposed replacement of DNR with “allow natural death” . Prior to this investigation, no scientific papers address the impact of such a change. Our results support this proposition due to increased likelihood of endorsement with the term AND.

Despite the ongoing consideration of the ethical nature of human resource management (HRM), little research has been conducted on how morality and ethics are represented in the discourse, activities and lived experiences of human resource (HR) professionals. In this paper, we connect the thinking and lived experiences of HR professionals to an alternative ethics, rooted in the work of Bauman (Modernity and the Holocaust, Polity Press, Cambridge, 1989; Theory, Culture and Society 7:5-38, 1990; Postmodern Ethics, Blackwell, Oxford, 1991; Approaches to (...) Social Enquiry, Polity Press, Cambridge, 1993; Life in Fragments, Blackwell, Oxford, 1995) and Levinas (Otherwise than Being, or, Beyond Essence, Duquesne University Press, Pittsburgh, PA, 1998). We argue that the study of HRM and ethics should be contextualized within the discourses used, the practices and activities of HR professionals. Through the analysis of interview data from 40 predominantly Canadian HR practitioners and managers we experiment with Bauman's notion of 'moral impulse' to help us understand how HRM is both a product and perpetuator of moral neutralization in organizations. We suggest that HRM as it is practiced is concerned with distancing, depersonalizing, and dissembling, and acts in support of the 'moral' requirements of business, not of people. However, we also recognize that HR practitioners and managers are often confronted with and conflicted by actions and decisions that they are required to take, therefore opening possibilities and hope for an alternative ethical HRM.

The appeal to expert opinion is an argument form that uses the verdict of an expert to support a position or hypothesis. A previous scheme-based treatment of the argument form is formalized within a Bayesian network that is able to capture the critical aspects of the argument form, including the central considerations of the expert's expertise and trustworthiness. We propose this as an appropriate normative framework for the argument form, enabling the development and testing of quantitative predictions as to how (...) people evaluate this argument, suggesting that such an approach might be beneficial to argumentation research generally. We subsequently present two experiments as an example of the potential for future research in this vein, demonstrating that participants' quantitative ratings of the convincingness of a proposition that has been supported with an appeal to expert opinion were broadly consistent with the predictions of the Bayesian model.
