CO oxidation on Pd(100) and Pd(111): A comparative study of reaction pathways and reactivity at low and medium coverages

We have performed density functional theory calculations with the generalized gradient approximation to investigate CO oxidation on a close-packed transition metal surface, Pd(lll), and a more open surface, Pd(100), aiming to shed light on surface structure effects on reaction pathways and reactivity, an important issue in catalysis. Reaction pathways on both surfaces at two different coverages have been studied. It is found that the reaction pathways on both surfaces possess crucial common features despite the fact that they have different surface symmetries. Having determined reaction barriers in these systems, we find that the reaction on Pd(lll) is strongly coverage dependent. Surface coverages, however, have little effect on the reaction on Pd(100). Calculations also reveal that the low coverage reactions are structure sensitive while the medium coverage reactions are not. Detailed discussions on these results are given.

How could Human Rights Law be used by the Courts to assist Victims of Domestic Violence? A Comparative Study

It has been increasingly recognised in recent years that domestic violence constitutes a human rights issue. This article seeks to shed light on the question of how human rights law may be used in the area of domestic violence through the medium of a litigation strategy. The method used is a comparative assessment of the approaches taken towards gender issues by the Constitutional Courts in three states that have famously dynamic judiciaries- India, South Africa and Canada. A number of the obstacles to the effectiveness of human rights law are also examined.

The Rights of Religious Associations to External Relations: A Comparative Study of the OSCE and the Council of Europe

This paper argues that religious associations have a number of substantive rights when it comes to their external relations. It does so though comparing the position of the OSCE and the Council of Europe. This paper considers whether the emerging framework includes: (1) a right to legal entity status, (2) a right to establish and run charitable or educational institutions, (3) a right to privileges and substantive benefits and (4) a right to anything else. It concludes that the current developments are welcome because religious freedom has a collective aspect that is essential to the lives of many believers.

Impact of PSA testing and prostatic biopsy on cancer incidence and mortality: comparative study between the Republic of Ireland and Northern Ireland

Objectives: To investigate the impact of different PSA testing policies and health-care systems on prostate cancer incidence and mortality in two countries with similar populations, the Republic of Ireland (RoI) and Northern Ireland (NI).

Methods: Population-level data on PSA tests, prostate biopsies and prostate cancer cases 1993–2005 and prostate cancer deaths 1979–2006 were compiled. Annual percentage change (APC) was estimated by joinpoint regression.

Results: Prostate cancer rates were similar in both areas in 1994 but increased rapidly in RoI compared to NI. The PSA testing rate increased sharply in RoI (APC = +23.3%), and to a lesser degree in NI (APC = +9.7%) to reach 412 and 177 tests per 1,000 men in 2004, respectively. Prostatic biopsy rates rose in both countries, but were twofold higher in RoI. Cancer incidence rates rose significantly, mirroring biopsy trends, in both countries reaching 440 per 100,000 men in RoI in 2004 compared to 294 in NI. Median age at diagnosis was lower in RoI (71 years) compared to NI (73 years) (p < 0.01) and decreased significantly over time in both countries. Mortality rates declined from 1995 in both countries (APC = -1.5% in RoI, -1.3% in NI) at a time when PSA testing was not widespread.

Conclusions: Prostatic biopsy rates, rather than PSA testing per se, were the main driver of prostate cancer incidence. Because mortality decreases started before screening became widespread in RoI, and mortality remained low in NI, PSA testing is unlikely to be the explanation for declining mortality.

A comparative study of nursing attitudes towards young male survivors of brain injury: A questionnaire survey.

Background The attitudes members of the nursing profession hold towards survivors of brain injury may impact on the level of help, and degree of involvement they are willing to have. Given that the manner in which an individual receives their brain injury has been shown to impact on public prejudices, the importance of exploring nursing attitudes to this vulnerable group, and the subsequent impact this may have on the caring role, requires investigation. Objective To investigate the attitudes held by members of the nursing profession towards young male survivors of brain injury whose behaviour either contributed, or did not contribute, to their injury. Design Independent groups design. Setting and participants Ninety trainee and sixty-nine qualified nurses respectively drawn from a university in the south west of England and the emergency, orthopaedic and paediatric Departments of the Royal Devon and Exeter Hospital, UK. Methods Participants were randomly assigned to one of four fictional brain injury scenarios. A young male character was portrayed as sustaining a brain injury as a result of either an aneurysm, or through drug taking, with their behaviour being either a contributory or non-contributory factor. On reading these, participants were asked to complete the prejudicial evaluation scale, the social interaction scale and the helping behaviour scale. Results Analysis of variance showed that qualified nurses held more prejudicial attitudes than student nurses towards survivors of brain injury. Mean scores indicated that individuals seen as contributing towards their injury were likely to experience more prejudice (blame total = 42.35 vs. no blame total = 38.34), less social interaction (blame total = 37.54 vs. no blame total = 41.10), and less helping behaviour (blame total = 21.49 vs. no blame total = 22.34) by both groups. Conclusions Qualified nurses should be mindful of the impact their attitudes and judgements of survivors of brain injury may have on the subsequent care they provide. Greater emphasis on the effects of negative attitudes on patient interactions during training may provide nurses with the understanding to recognise and avoid challenges to their caring role in the future.

A comparative study of domestic, European and international job-related relocation

This paper explores a number of relocation outcomes for geographically mobile employees in the following three regions: Germany as the home country and destination for domestic assignments (n = 115), Western Europe (n = 116) and other countries (n = 236). The satisfaction with various aspects of the post-relocation environment, the perception of change between the pre- and post-relocation environment and the attachment to the post-relocation environment at various levels were compared between the three groups. For the European and international sub-samples differences in the ideal country and future plans were also investigated. The group that stood out most clearly was the domestic sub-sample. It emerged as the group least satisfied with their job or task characteristics, perceived significantly fewer changes in the environment and was comparatively eager to leave the site they were currently working at and the job they were currently employed in. The sometimes proposed redefinition of intra-European assignments as ‘quasi-domestic’ relocation appears to be inappropriate.

A COMPARATIVE STUDY OF LASAEA AUSTRALIS, VULSELLA SPONGIARUM, PINNA BICOLOR AND DONACILLA CUNEATA (MOLLUSCA; BIVALVIA) FROM PRINCESS ROYAL HARBOUR, WESTERN AUSTRALIA

Monthly samples of L. australis, V. spongiartum, P. bicolor and D. cuneata were collected over a period of 12 months from Princess Royal Harbour, Western Australia. Preliminary information on densities and biomass is given. Gonad histology points to seasonal reproductive cycles with autumn spawning in P. bicolor and D. cuneata and irregular spawning in V. spongiantm and L. australis. However, L. australis did show two peaks of larval brooding in the study period. Length-frequency data are discussed in the light of the proposed reproductive patterns for the four species. Allometric relationships between length and both height and width for all species are described and their value to each species assessed. Populations of L. australis from different habitats show significant differences in shell shape.
