The eclipse of Epsilon Aurigae visible spectroscopy and ultraviolet activity
The preliminary results of the study of several high resolution spectrograms (lambda 3500 - lambda 7000 A), obtained at the Haute Provence Observatory (OHP) in France, at different epochs before, during and after the eclipse are reported. Some of these spectrograms are compared with corresponding IUE high resolution observations, in order to study the effects of the intrinsic UV activity, towards the longer wavelengths
IUE observations of blue halo high luminosity stars
Two high luminosity population II blue stars of high galactic latitude, BD+33 deg 2642 and HD 137569 were observed at high resolution. The stellar spectra show the effect of mass loss in BD+33 deg 2642 and abnormally weak metallic lines in HD 137569. The interstellar lines in the direction of BD+33 deg 2642, which lies at a height z greater than or equal to 6.2 kpc from the galactic plane, are split into two components. No high ionization stages are found at the low velocity component; nor can they be detected in the higher velocity clouds because of mixing with the corresponding stellar/circumstellar lines
Self-interacting Dark Matter and Invisibly Decaying Higgs
Self-interacting dark matter has been suggested in order to overcome the
difficulties of the Cold Dark Matter model on galactic scales. We argue that a
scalar gauge singlet coupled to the Higgs boson, which could lead to an
invisibly decaying Higgs, is an interesting candidate for this self-interacting
dark matter particle. We also present estimates on the abundance of these
particles today as well as consequences to non-Newtonian forces.Comment: 4 pages, Revte
Study protocol: addressing evidence and context to facilitate transfer and uptake of consultation recording use in oncology: a knowledge translation implementation study
Background:
The time period from diagnosis to the end of treatment is challenging for newly diagnosed cancer patients. Patients have a substantial need for information, decision aids, and psychosocial support. Recordings of initial oncology consultations improve information recall, reduce anxiety, enhance patient satisfaction with communication, and increase patients' perceptions that the essential aspects of their disease and treatment have been addressed during the consultation. Despite the research evidence supporting the provision of consultation recordings, uptake of this intervention into oncology practice has been slow. The primary aim of this project is to conduct an implementation study to explicate the contextual factors, including use of evidence, that facilitate and impede the transfer and uptake of consultation-recording use in a sample of patients newly diagnosed with breast or prostate cancer.
Methods:
Sixteen oncologists from cancer centres in three Canadian cities will participate in this three-phase study. The preimplementation phase will be used to identify and address those factors that are fundamental to facilitating the smooth adoption and delivery of the intervention during the implementation phase. During the implementation phase, breast and prostate cancer patients will receive a recording of their initial oncology consultation to take home. Patient interviews will be conducted in the days following the consultation to gather feedback on the benefits of the intervention. Patients will complete the Digital Recording Use Semi-Structured Interview (DRUSSI) and be invited to participate in focus groups in which their experiences with the consultation recording will be explored. Oncologists will receive a summary letter detailing the benefits voiced by their patients. The postimplementation phase includes a conceptual framework development meeting and a seven-point dissemination strategy.
Discussion:
Consultation recording has been used in oncology, family medicine, and other medicine specialties, and despite affirming evidence and probable applications to a large number of diseases and a variety of clinical contexts, clinical adoption of this intervention has been slow. The proposed study findings will advance our conceptual knowledge of the ways to enhance uptake of consultation recordings in oncology
Globalisation and HR practices in Africa: When culture refuses to make way for so-called universalistic perspectives
The paper demonstrates and exemplifies how cultural paradigms and the political and socio-economic spheres and organisational life are intertwined in an African context.
The paper examines how some factors that are embedded in the cultural and institutional framework in Sub-Saharan African organisations interact with global perspectives and the degree of resistance they present to changes in human resource management (HRM) processes. The paper considers aspects of the universalistic perspectives that have resonance for human resource practices in Africa. Furthermore, it evaluates the question of the tensions between the contributions derived from the indigenous and historical factors, and the inputs from external sources, to human resource management in Africa. rnThe research is based on a survey of 100 practicing African human resources professionals. The respondents were drawn from the major institutional actors in Nigeria. rnThe research found that, despite the impact of globalisation and the Westernisaion of training and development in Africa, HRM practices remain largely culture-bound. Many aspects of Sub-Saharan African cultures pervade organisational processes, e.g. collectivism and paternalism, that refuse to make way for change. However, the paper concludes that some of these temerarious cultural aspects that are often described as counter-productive in much of the literature, could actually be utilised for community and employee engagement. rnThe paper makes a significant contribution to the literature on HRM practices in Africa, an area under-researched. It provides an opportunity to African HR managers to be more pragmatic in identifying the contextual issues and for beginning to identify aspects of African culture that could be value-adding in a fast changing management landscape. The paper demonstrates that HRM policies have specific cultural orientations and reflect on both the societal predispositions of the region; this exemplifies how cultural paradigms, the political sphere and organisational life are intertwined in an African context
Resisting global universalistic practices - the endurance of culture and particularism in African HRM
Purpose
This article empirically assesses the extent to which factors rooted in the cultural and institutional framework in Sub-Saharan African organisational contexts challenge and resist the penetration of global practices and how these dynamics impact on human resource management (HRM). This article examines universalistic perspectives are significant for African HRM. The article discusses the tensions between the contributions derived from local and historical factors, and that of other environmental agents, to African HRM practice.
Design/methodology
The study is based on a survey among 100 practising African HRM executives representing significant organisations in Sub-Saharan Africa.
Findings
The main findings established that, in spite of Westernisation and globalising trends in learning and development in Africa, human resource practices are still profoundly embedded in the African cultural fabric. Significant elements of cultures in Sub-Saharan Africa pervade organisational processes; such aspects include collectivism and paternalism, which persistently resist change. The article, however, concludes that the resisting parts of Sub-Saharan African cultures which are viewed as counter-productive, can have positive resonance if constructively deployed.
Originality
This article contributes to African HRM literature, a significantly under-researched field. The paper provides an opportunity for African HR managers to be more pragmatic in identifying the contextual issues as well as aspects of African culture that could be value-adding in a fast-changing managerial field. The findings demonstrate that human resource strategies and policies have specific cultural orientations and reflect the societal predispositions of a particular collectivity; this epitomizes the intertwining of cultural paradigms, political spheres and organisational life in Sub-Saharan Afric
