    Investors Activism and the Gains from Takeover Deals

    We examine whether activists add value to the shareholders of targets and their acquirers. Several findings emerge. First, acquirers of targets that have activists outperform acquirers of other targets in both the short and long term. Second, the premium received by the shareholders of targets is not affected by activism. Third, superior gains achieved by the acquirers of targets with activists are driven by non-cash deals, while the average target benefits more from cash deals

    The health and wellbeing of offshore workers: a narrative review of the published literature.

    Get PDF
    Recent developments within the offshore industry have highlighted the role that health and wellbeing plays in ensuring the safety and longevity of the offshore workforce. Developing an understanding of the overall health and wellbeing of offshore workers could aid future developments. This narrative review aims to identify and synthesise the relevant published literature on offshore health and wellbeing. The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Medical Literature Analysis and Retrieval System Online, PsycArticles, and Web of Science databases were searched with publication search dates limited from January 1994 to November 2014. Twenty-six studies were identified and covered aspects of occupational stress; mental wellbeing; body mass index; diet; physical activity; musculoskeletal disorder; smoking; alcohol and drug use; shift work amongst offshore workers. This narrative review has highlighted a lack of high quality and relevant research. There is a particular need to research workers' participation in self care activities and the resultant influence of domains on health and well being.

    Complex magnetism of lanthanide intermetallics unravelled

    Get PDF
    We explain a profound complexity of magnetic interactions of some technologically relevant gadolinium intermetallics using an ab-initio electronic structure theory which includes disordered local moments and strong ff-electron correlations. The theory correctly finds GdZn and GdCd to be simple ferromagnets and predicts a remarkably large increase of Curie temperature with pressure of +1.5 K kbar1^{-1} for GdCd confirmed by our experimental measurements of +1.6 K kbar1^{-1}. Moreover we find the origin of a ferromagnetic-antiferromagnetic competition in GdMg manifested by non-collinear, canted magnetic order at low temperatures. Replacing 35\% of the Mg atoms with Zn removes this transition in excellent agreement with longstanding experimental data.Comment: 11 pages, 4 figure

    When you are homeless, you are not thinking about your medication, but your food, shelter or heat for the night: behavioural determinants of homeless patients' adherence to prescribed medicines.

    Objectives This study aimed to explore behavioural determinants of homeless patients' adherence to prescribed medicines using Theoretical Domains Framework (TDF). Study design A qualitative study using semi-structured, face-to-face interviews. Methods Participants were recruited from a homelessness primary healthcare centre in Aberdeen, United Kingdom (UK). Face-to-face interviews were audio-recorded and transcribed verbatim. Thematic analysis of the interview data was conducted using the Framework Approach based on the Theoretical Domains Framework. National Health Service ethical and Research and Development (R&D) approval was obtained. Results Twenty-five patients were interviewed, at which point data saturation was achieved. A total of 13 out of 14 Theoretical Domains Framework domains were identified that explained the determinants of adherence or non-adherence to prescribed medicines. These included: beliefs about consequences (e.g. non-adherence leading to poor health); goals of therapy (e.g. being a normal person with particular reference to methadone adherence); and environmental context and resources (e.g. stolen medicines and the lack of secure storage). Obtaining food and shelter was higher priority than access and adherence to prescribed medicines while being homeless. Conclusions Behavioural determinants of non-adherence identified in this study were mostly related to participants' homelessness and associated lifestyle. Results are relevant to developing behaviour change interventions targeting non-adherent homeless patients and to the education of healthcare professionals serving this vulnerable population

    Phase stability analysis in Fe-Pt and Co-Pt alloy systems: An augmented space study

    Full text link
    We have studied the problem of phase stability in Fe-Pt and Co-Pt alloy systems. We have used the orbital peeling technique in the conjunction of augmented space recursion based on the tight binding linear orbital method as the method for the calculation of pair interaction energies. In particular, we have generalized our earlier technique to take into account of magnetic effects for the cases where the magnetic transition is higher than the order disorder chemical transition temperature as in the case of Co3_3Pt. Our theoretical results obtained within this framework successfully reproduce the experimentally observed trends.Comment: 17 pages, 9 Figures.
