We consider the contribution of neutron stars and black holes to the dynamical mass of galactic halos. In particular, we show that if these compact objects were produced by an early generation of stars with initial metallicity ∼< 10 Z⊙, they can contribute up to 30–40% of the Galactic halo mass without violating constraints from chemical evolution. This scenario is consistent with the recent re...

One of the more controversial elements of advancing technology is the use of race and genetics to help create more specific types of medicines that will help combat diseases and conditions that appear to be more prevalent within certain races or ethnic groups than in others. Considering the history of discrimination and inadequate treatment of individuals on the bases of race and gender in the ...

International health policy-makers now have a variety of institutional instruments with which to pursue their global and national health goals. These instruments range from the established formal multilateral organizations of the United Nations to the newer restricted-membership institutions of the Group of Eight (G8). To decide where best to deploy scarce resources, we must systematically exam...

A study of the effect of deformation and pairing on the development of halo nuclei is presented. Exploratory three-body core + n + n calculations show that both the NN interaction and the deformation/excitation of the core hinder the formation of the halo. Preliminary self-consistent mean-field calculations are used to search for regions in the nuclear chart where halos could potentially develo...

The three-body description of two-neutron halo nuclei relies on the two-body interactions between the constituents. In order to provide constraints on calculations devoted to 14 Be and 17 B, the neutron unbound states of 13 Be and 16 B have been investigated by one-proton knockout. The experimental techniques and results are discussed here.

Community health psychology is concerned with the theory and method of working with communities to combat disease and to promote health. This introductory article outlines key assumptions and debates underlying this area of research and practice-in the interests of framing the papers in this special edition of the Journal of Health Psychology. Attention is given to the value of emphasizing the ...

Though the broader literature suggests that women may be more vulnerable to the effects of trauma exposure, most available studies on combat trauma have relied on samples in which women's combat exposure is limited and analyses that do not directly address gender differences in associations between combat exposure and postdeployment mental health. Female service members' increased exposure to c...

AIMS Since the start of the conflicts in Iraq and Afghanistan, the numbers of young service personnel who have sustained a combat-related visual impairment have increased. This cross-sectional study examined the mental well-being of ex-servicemen (aged 22-55 years) with a visual impairment and determined if the mental health of those with a combat-related visual impairment differed from those w...
