Spin gauge models use a real Clifford algebraic structure Rp,q associated with a real manifold of dimension p + q to describe the fundamental interactions of elementary particles. This review provides a comparison between those models and the standard model, indicating their similarities and differences. By contrast with the standard model, the spin gauge model based on R3,8 generates intermediate boson mass terms without the need to use the Higgs-Kibble mechanism and produces a precise prediction for the mass of the (...) top quark. The potential of this model to account for exactly three families of fermions is considered. (shrink)

The rapid emergence and exploding usage of online social networking forums, which are frequented by millions, present clinicians with new ethical and professional challenges. Particularly among a younger generation of physicians and patients, the use of online social networking forums has become widespread. In this article, we discuss ethical challenges facing the patient–doctor relationship as a result of the growing use of online social networking forums. We draw upon one heavily used and highly trafficked forum, Facebook, to illustrate the elements (...) of these online environments and the ethical challenges peculiar to their novel form of exchange. Finally, we present guidelines for clinicians to negotiate responsibly and professionally their possible uses of these social forums. (shrink)

The tension between public duty and private conscience is a central theme of English history in the seventeenth century, when established authorities were questioned and violently disrupted. It has also been an important theme in the work of one of the foremost historians of the period, G.E. Aylmer. It makes, therefore, an especially appropriate subject for this volume. The contributors are leading historians, whose topics range from contemporary writings on conscience and duty to the particular problems faced by individuals and (...) groups, both Puritan and Royalist, at the center and in the localities. These scholarly and original studies throw new light on the innumberable dilemmas of conscience of seventeenth-century men and women, and together make a distinguished contribution to seventeenth-century history.

There is usually great concern over the use of psychiatric patients for clinical research, as it raises the ethical and legal issues of human dignity and autonomy. In this paper the authors describe and evaluate a follow-up neurobiological study of patients who had been discharged from a psychiatric research ward at least ten months earlier. It is pointed out that such studies are rare and that the writers were provided with the unique opportunity to examine attitudinal and motivational dimensions involved (...) in the patients' agreement to participate in the study.

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.
