The moral relevance of personal characteristics in setting health care priorities
This paper discusses the moral relevance of accounting for various personal characteristics when prioritising between groups of patients. After a review of the results from empirical studies, we discuss the ethical reasons which might explain – and justify – the views expressed in these studies. The paper develops a general framework based upon the causes of ill health and the consequences of treatment. It then turns to the question of the extent to which a personal characteristic – and the eventual underlying ethical justification of its relevance – could have any relationships to these causes and consequences. We attempt to disentangle those characteristics that may reflect a potentially relevant justification from those which violate widely accepted principles of social justice.Health care priorities; Ethics; Personal responsibilities; Consequences
Coincidence of topological Jacobson radicals in topological algebras
Several classes of topological algebras for which the left topological Jacobson radical coincides with the right topological Jacobson radical are described
DETERMINING PHYSICAL CONDITIONS IN STAR FORMING REGIONS
This dissertation is a study of the physical conditions in star-forming regions, and combines observational data and theoretical calculations. We studied the physical conditions of Orions Veil, which is an absorbing screen that lies along the line of sight to the Orion H II region. We computed photoionization models of the Veil. We combined calculations with UV, radio, and optical spectra that resolve the Veil into two velocity components. We derive many physical parameters for each component seen in 21 cm absorption. We find the magnetic field energy dominates turbulent and thermal energies in one component while the other component is close to equipartition between turbulent and magnetic energies. We observe H2 absorption for highly excited levels. We find that the low ratio of H2/H0 in the Veil is due to the high UV flux incident upon the Veil. We detect blueshifted S+2 and P+2 ions which must arise from ionized gas between the neutral portions of the Veil and the Trapezium and shields the Veil from ionizing radiation. We determine the ionized and neutral layers of the Veil will collide in less than 85,000 years. The second part of this dissertation involved self-consistently calculating the thermal and chemical structure of an H II region and photodissociation region (PDR) that are in pressure equilibrium. This differs from previous work, which used separate calculations for each gas phase. Our calculations span a wide range of initial conditions. We describe improvements made to the spectral synthesis code Cloudy which made these calculations possible. These include the addition of a molecular network with ~1000 reactions involving 68 molecules and improved treatment of the grain physics. Archival data are used to derive important physical characteristics of observed H II regions and PDRs. These include stellar temperatures, electron densities, ionization parameters, UV flux, and PDR density. The contribution of the H II region to PDR emission line diagnostics is also calculated. Finally, these calculations are used to derive emission line ratios than can tell us the equation of state in star-forming regions

Familial and peer influences on sport participation among adolescents in rural South African secondary schools
This study was designed to investigate the influences of family and peers on sport participation amongst adolescents in secondary schools at Hlanganani rural area of Limpopo Province, South Africa. A total of 172 learners (108 females and 64 males) attending three public secondary schools in Hlanganani rural area volunteered to participate in the study. Results indicated that adolescents preferred peers to family for support in sport participation. In terms of gender, no significant differences (p>0.05) were noted between mean values for school boys and girls with regard to family influence. Boys reported more tangible support, whereas girls indicated a preference for emotional support. Sport participation among learners is likely to increase when they receive informational, tangible, emotional and appraisal support from their parents and peers
Bounded gaps between primes in number fields and function fields
The Hardy--Littlewood prime -tuples conjecture has long been thought to be
completely unapproachable with current methods. While this sadly remains true,
startling breakthroughs of Zhang, Maynard, and Tao have nevertheless made
significant progress toward this problem. In this work, we extend the
Maynard-Tao method to both number fields and the function field
