Prevention of MSD within OHSMS/IMS: a systematic review of risk assessment strategies

The purpose of this systematic review was to identify and summarize the research evidence on prevention of Musculoskeletal Disorders (MSD) within Occupational Health and Safety Management Systems (OHSMS) and Integrated Management Systems (IMS). Databases in business, management, engineering and health and safety were systematically searched and relevant publications were synthesized. The number of papers that could address the research questions was small. However, the review revealed that many of the techniques to address MSD hazards require substantial background knowledge and training. This may limit employees' involvement in the technical aspects of the risk assessment process. Also these techniques did not usually fit into techniques used by companies to address other risk factors within their management systems. This could result in MSD prevention becoming a separate issue that cannot be managed with company-wide tools. In addition, this review also suggested that there is a research gap concerning the MSD prevention within companies' management systems.     

Social Capital in Association with Socioeconomic Variables in Iran

The objective of this study was to determine the various dimensions of social capital in Tehran and its association with socioeconomic variables. Two thousand, four hundred and eighty-four persons participated in the study through multi-stage stratified sampling in Tehran. The study questions were extracted from the World Bank integrated questionnaire. While respondents obtained over 50 % of the attainable scores in the ‘trust’, ‘cooperation’, ‘social cohesion’, and ‘political action’ dimensions, they obtained only 18.9 % of the attainable scores in the ‘networks’ dimension. The respondents in age groups older than 45 had higher trust scores than respondents in the 18–25 age group. Men had higher ‘network’ and ‘social cohesion’ scores than women (p ≤ 0.001). Respondents in the poorest wealth quintile had lower ‘networks’ and ‘social cohesion’ scores than the richest group and ‘political action’ scores higher than the richest group (p = 0.038). The lowest score in ‘Tehranians’ social capital was in the groups and networks dimension. Therefore designing effective interventions for such activities, particularly in women’s groups, is a priority.     

The Effect of Losses Disguised as Wins and Near Misses in Electronic Gaming Machines: A Systematic Review

Near misses and losses disguised as wins have been of interest to gambling researchers and policymakers for many years (e.g., Griffiths in J Gambl Stud 9(2):101–120, 1993). This systematic literature review describes the behavioural, psychological, and psychobiological effects of near misses and losses disguised as wins (LDWs) in an effort to evaluate their precise influence on the player and to highlight areas requiring further investigation. A systematic search for relevant studies was conducted using Scopus, PubMed, PsycINFO, ProQuest Sociology databases, and the Gambling Research Exchange Ontario Knowledge Repository. A total of 51 (from an initial pool of 802) experimental peer-reviewed studies using human participants were found between 1991 and 2015. The systematic review revealed that near misses motivate continued play, but have varying effects on the emotional state or betting behaviour of the player. Near miss events were also shown to be associated with elevated skin conductance levels and diffuse activity across the brain, most consistently in areas processing reinforcement and reward. Re-examination of the studies of near misses events after classifying the type of game feedback suggested that the effectiveness of near misses is related to the phenomenology of a near miss itself rather than as a response to auditory or visual feedback provided by a slot machine. In contrast to near misses, the presence of LDWs was found to relate to an overestimation of how much a player is actually winning and was consistently viewed as an exciting event. The effect of LDWs appears to be driven by the presence of visuals and sounds most often associated with a true win. Practical implications and directions for future research are also discussed.
