    "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

    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

    Effects of state recovery on creep buckling under variable loading

    Get PDF
    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

    Design of a "Digital Atlas Vme Electronics" (DAVE) Module

    Get PDF
    ATLAS-SCT has developed a new ATLAS trigger card, 'Digital Atlas Vme Electronics' ("DAVE"). The unit is designed to provide a versatile array of interface and logic resources, including a large FPGA. It interfaces to both VME bus and USB hosts. DAVE aims to provide exact ATLAS CTP (ATLAS Central Trigger Processor) functionality, with random trigger, simple and complex deadtime, ECR (Event Counter Reset), BCR (Bunch Counter Reset) etc. being generated to give exactly the same conditions in standalone running as experienced in combined runs. DAVE provides additional hardware and a large amount of free firmware resource to allow users to add or change functionality. The combination of the large number of individually programmable inputs and outputs in various formats, with very large external RAM and other components all connected to the FPGA, also makes DAVE a powerful and versatile FPGA utility cardComment: 8 pages, 4 figures, TWEPP-2011; E-mail: [email protected]

    Study of providing omnidirectional vibration isolation to entire space shuttle payload packages

    Get PDF
    Techniques to provide omnidirectional vibration isolation for a space shuttle payload package were investigated via a reduced-scale model. Development, design, fabrication, assembly and test evaluation of a 0.125-scale isolation model are described. Final drawings for fabricated mechanical components are identified, and prints of all drawings are included

    On the Approximation Performance of Fictitious Play in Finite Games

    Full text link
    We study the performance of Fictitious Play, when used as a heuristic for finding an approximate Nash equilibrium of a 2-player game. We exhibit a class of 2-player games having payoffs in the range [0,1] that show that Fictitious Play fails to find a solution having an additive approximation guarantee significantly better than 1/2. Our construction shows that for n times n games, in the worst case both players may perpetually have mixed strategies whose payoffs fall short of the best response by an additive quantity 1/2 - O(1/n^(1-delta)) for arbitrarily small delta. We also show an essentially matching upper bound of 1/2 - O(1/n)
