Next SectionIncreasingly a focus of research as well as media reports and online forums, the use of placebos in clinical medicine extends beyond sugar pills and saline injections. Physician surveys conducted in various countries invariably report that placebos are routinely used clinically, impure placebos more frequently than the pure ones, and that physicians consider them to be of legitimate therapeutic value. Inconsistent study methodologies and physician conceptualisations of placebos may complicate the interpretation of survey data, but hardly negate the valuable (...) insights these research findings provide. Because impure placebos are often not recognised as such by practitioners, they remain at the fringe of many placebo-related debates, hence quietly absent from discussions concerning policy and regulation. The apparent popularity of impure placebos used in clinical practice thus presents unresolved ethical concerns and should direct future discussion and research. (shrink)

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 ….

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.

Although it is clear that i-frame approaches cannot stand alone, the impact of s-frame changes can plateau. Combinations of these approaches may best reflect what we know about behavior and how to support behavioral change. Interactions between i-frame and s-frame thinking are explored here using two examples: alcohol consumption and meat consumption.

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.

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.

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.

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)

Homegardens are traditional food systems that have been adapted over generations to fit local cultural and ecological conditions. They provide a year-round diversity of nutritious foods for smallholder farming communities in many regions of the tropics and subtropics. In southwestern Uganda, homegardens are the primary source of food, providing a diverse diet for rural marginalized poor. However, national agricultural development plans as well as economic and social pressures threaten the functioning of these homegardens. The implications of these threats are difficult (...) to evaluate, because the structure and functions of the homegardens are not well understood. The aim of the study was to identify patterns and influencing factors in the diversity of homegardens by documenting the floristic diversity and its interactions with spatial, environmental and socio-economic factors. A geographically and socially focused assessment of floristic diversity in 102 randomly selected homegardens in three districts of southwest Uganda was conducted along a deforestation gradient following a human ecology conceptual framework and testing multiple quantitative hypotheses regarding the above mentioned factors. A merged mixed-method approach was followed to provide context and feedback regarding quantitative findings. Results show a high total richness of 209 crop species dominated by food species, which constituted 96 percent of individuals and 44 percent of all species. Forest-edge homegardens maintained higher plant diversity compared to homegardens in deforested areas and near degraded wetlands. Multiple linear regression models indicated elevation, location, homegarden size, distance to market, additional land ownership and livestock ownership as significant predictors of crop diversity. Cluster analysis of species densities revealed four garden types: ‘diverse tree gardens’, ‘small forest-edge gardens’, ‘large, old, species-rich gardens’, and ‘large, annual-dominated herb gardens’, with 98% correct classification. Location, elevation, and garden size were also important determinants in the cluster assignment. We conclude that the diversity of the studied homegardens may be changing as part of adaptive traditional practices and in response to external drivers. The identified patterns illustrate the importance of homegardens for rural livelihoods and may offer some ways to support farmers to maintain these systems as relevant mechanisms for development in Uganda.

This paper discusses the provocative views of Skene and Parker as to the role of religious or other ideologically based interest groups in law and policy making. We draw distinctions between doctrine and prejudice and between argument and ideology which we trust take the debate further. Finally we recommend an ethereal, democratic, and populist partial solution.

The first translation into English and the first detailed interpretation of Hegel’s System der Sittlichkeit and of Philosophie des Geistes, the two earliest surviving versions of Hegel’s social theory. Hegel’s central concept of the spirit evolved in these two works. An 87-page interpretation by Harris precedes the translations.

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)

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.
