"Talk" about male suicide? Learning from community programmes

Purpose – The purpose of this paper is to examine the contribution of public awareness campaigning in developing community capacity toward preventing male suicide and explores emerging considerations for suicide prevention programme development. Design/methodology/approach – The paper draws on campaign evaluation data, specifically qualitative discussion groups with the general public, to report results concerning campaign processes, and “interim” effectiveness in changing public awareness and attitudes, and then discusses how progress is to be lasting and transformational. Findings – The campaign raised the awareness of a substantial proportion of those targeted, and affected attitudes and behaviour of those who were highly aware. The community settings approach was effective in reaching younger men, but there were challenges targeting the public more selectively, and engaging communities in a sustained way. Practical implications – The paper discusses emerging considerations for suicide prevention, focusing on gender and approaches and materials for engaging with the public as “influencers”. There are challenges to target audiences more specifically, provide a clear call to action, and engage the public in a sustained way. Social implications – The paper discusses emerging considerations for suicide prevention, focusing on gender and approaches and materials for engaging with the public as “influencers”. There are challenges to target audiences more specifically, provide a clear call to action, and engage the public in a sustained way. Originality/value – The paper adds fresh evidence of gendered communication processes, including their effects on public awareness, attitudes and engagement. Application of a theory of change model leads to systems level findings for sustaining programme gains

Effects of state recovery on creep buckling under variable loading

Structural alloys embody internal mechanisms that allow recovery of state with varying stress and elevated temperature, i.e., they can return to a softer state following periods of hardening. Such material behavior is known to strongly influence structural response under some important thermomechanical loadings, for example, that involving thermal ratchetting. The influence of dynamic and thermal recovery on the creep buckling of a column under variable loading is investigated. The column is taken as the idealized (Shanley) sandwich column. The constitutive model, unlike the commonly employed Norton creep model, incorporates a representation of both dynamic and thermal (state) recovery. The material parameters of the constitutive model are chosen to characterize Narloy Z, a representative copper alloy used in thrust nozzle liners of reusable rocket engines. Variable loading histories include rapid cyclic unloading/reloading sequences and intermittent reductions of load for extended periods of time; these are superimposed on a constant load. The calculated results show that state recovery significantly affects creep buckling under variable loading. Structural alloys embody internal mechanisms that allow recovery of state with varying stress and time

The use of theory in research relating to open access: practitioner perspectives

The relationship between theory and practice has long been considered problematic for many applied academic disciplines. In this short paper we report preliminary findings from a two‐year research project investigating the ways and the extent that theory and practice have interacted in the development of open‐access (OA) approaches to the publishing and dissemination of research outputs. Based on interviews with practitioners and researchers working on OA related issues, we explore the ways in which theory is (and isn't) of value to practice. We find that while practitioners acknowledge that theory has the potential to improve understanding, bestow credibility on work, and codify existing knowledge about OA, they also perceive it as “mood music” to the practical work of OA, lacking explicit links to action

Evaluation of the Choose Life North Lanarkshire Awareness Programme: Final Report

The Centre for Men’s Health at Leeds Metropolitan University, with consultants from MRC Social and Public Health Sciences Unit, Glasgow, and Men’s Health Forum, Scotland (MHFS), were appointed to conduct the Choose Life (North Lanarkshire) evaluation, beginning in March 2011. The key evaluation questions are: 1. How has the social marketing approach to increase awareness of crisis service numbers and de-stigmatise understandings and attitudes about suicide worked? 2. Has the programme as implemented been effective? Which aspects of the programme have been particularly effective? 3. Has this programme been of benefit to the community, in particular young men aged 16-35? 4. What contribution has the community made to the effectiveness of the programme

Unified Viscoplastic Behavior of Metal Matrix Composites

The need for unified constitutive models was recognized more than a decade ago in the results of phenomenological tests on monolithic metals that exhibited strong creep-plasticity interaction. Recently, metallic alloys have been combined to form high-temperature ductile/ductile composite materials, raising the natural question of whether these metallic composites exhibit the same phenomenological features as their monolithic constituents. This question is addressed in the context of a limited, yet definite (to illustrate creep/plasticity interaction) set of experimental data on the model metal matrix composite (MMC) system W/Kanthal. Furthermore, it is demonstrated that a unified viscoplastic representation, extended for unidirectional composites and correlated to W/Kanthal, can accurately predict the observed longitudinal composite creep/plasticity interaction response and strain rate dependency. Finally, the predicted influence of fiber orientation on the creep response of W/Kanthal is illustrated

Influencing public awareness to prevent male suicide

Purpose – The purpose of this paper is to report findings from a formative evaluation of a suicide prevention public awareness campaign – Choose Life, North Lanarkshire. The focus is on preventing male suicide. The paper explores how the public campaign supports a co-ordinated and community-based direction for suicide prevention work, and examines how good practice can be identified, spread, and sustained. Design/methodology/approach – The paper draws on data collected from March to November 2011, using mixed primary research methods, including a quota survey, discussion groups with the general public, and stakeholder interviews. Findings – The campaign effectively raised the suicide awareness of a substantial proportion of those targeted, but with regional variations. It also affected the attitudes and behaviour of those who were highly aware. However, men and women engaged somewhat differently with the campaign. The sports and leisure settings approach was effective in reaching younger men. Practical implications – The paper discusses emerging considerations for suicide prevention, focusing on gender and approaches and materials for engaging with the public as “influencers”. There are challenges to target audiences more specifically, provide a clear call to action, and engage the public in a sustained way. Originality/value – This paper reflects on insights from a complex programme, exceptional in its focus on targeted sections of the public, especially young males. The paper indicates the importance for research and practice of intersecting dimensions of male identity, stigma and mental health, and other risk and protective factors which can inform campaigns highlighting talk about suicide among men

Closed-drift thruster investigations

Recent data obtained from a second generation closed-drift thruster design, employing Hall current acceleration is outlined. This type device is emphasized for electric propulsion for geocentric mission applications. Because geocentric mission profiles are best achieved with a specific impulse range of 1000 to 2000 s, closed-drift thrusters are well suited for this application, permitting time payload compromises intermediate of those possible with either electrothermal or electrostatic devices. A discussion is presented of the potential advantages of using a 1000 to 2000 s device for one way orbit raising of nonpower payloads. Because closed-drift thruster operation is not space charge limited, and requires only one power circuit for steady state operation, their application is technically advantageous. Beam, plasma and thrust characteristics are detailed for a range of operating conditions
