Abstract: BACKGROUND: Improving Occupational Health and Safety performance has become a challenge for industry, because investing in technology, equipment, or robust management systems has not been enough to prevent accidents in the workplace. With the expansion of commercial relations and the intensification of competitiveness in the global market, leadership is essential to prevention. OBJECTIVE: Evaluate leadership in occupational safety through a case study. METHODS: The leadership training methodology “The seven steps of leadership and worker involvement” was adapted and applied. Data collection was conducted through the application of diagnosis, training, and monitoring of the evolution of the …leadership performance in the management of occupational safety via structured interviews, monitoring of accidents and statistical analysis of the data. RESULTS: Research has shown that assertive leadership behavior positively influences performance in the management of occupational safety and the results of this case study showed a reduction in accidents with injuries of more than 50%. CONCLUSIONS: Evidence shows that there is a correlation between safety leadership behavior and the reduction in the occurrence of accidents. Show more

Abstract: BACKGROUND: Non-automated tool handles transmit a large magnitude of vibration to operators’ hands, causing discomfort and pain. Therefore, the need for a better handle design is a matter of prime concern to overcome musculoskeletal disorders such as hand-arm vibration syndrome. OBJECTIVE: This study aimed to examine the influence of handle shapes in reducing the transmission of hand-arm vibration. METHODS: Seven different handles were designed and fabricated using 3D printing technology at the SSN College of Engineering, with consideration for the anatomical shape of the hand. The frequency-weighted Root Mean Square (RMS) values of the vibration levels …transmitted were recorded at the wrist of twelve subjects, unaffected by musculoskeletal disorders. Subjective ratings of vibration and comfort perception were measured using the Borg Scale of Perceived Exertion. RESULTS: The total vibration value (ahv ) of each of the six novel prototype handles (B-G) was compared to that of the reference handle denoted handle-A. The vibration reductions for handles B to G respectively were 0.542 m/s2 (14.59%), 0.481 m/s2 (12.95%), 0.351 m/s2 (9.45%), 0.270 m/s2 (7.27%), 0.407 m/s2 (10.96%) and 0.192 m/s2 (5.17%). CONCLUSIONS: A significant level of vibration reduction was achieved by the prototype handles. Qualitative feedback from the study subjects suggests that they were not aware of the levels of vibration being transmitted to the hand with each handle. Show more

Abstract: BACKGROUND: Industrialization and rising standards of living have contributed to a growing amount of solid waste and consequent disposal problems. Solid waste collection is among the occupations with the highest risk for musculoskeletal disorders. OBJECTIVE: We have conducted this study to assess musculoskeletal complaints and work-related stress levels among municipal solid waste (MSW) collectors. METHODS: The subjects were all currently employed at the MSW Department of the City of Ankara, Turkey. Validated questionnaires were completed by 267 MSW collectors. Data analysis was performed using SPSS software (22.0 version). RESULTS: Upper back pain rate was …89.1% among the collectors. 47.9% of collectors reported having had upper back pain during the last 12 months and 38.7% had experienced it during the last month. 80.9% of the sample complained of shoulder pain. Wrists/hands and neck pain rates were found at rates of 78.7% and 67.8% respectively. Psychological demands, were significantly higher among MSW collectors living with moderate-severe pain. CONCLUSIONS: Ergonomics education, healthy work habits, occupational safety training and improvements in the psychosocial work environment should be considered. Show more

Abstract: BACKGROUND: Progressive workplaces should be aware of emerging neurodiversity related issues. People are sharing their narratives of high functioning anxiety in a variety of forums. Despite news text reporting upon this phenomenon, the concept has managed to escape a research spotlight. OBJECTIVE: To critically investigate the evidence base of news article reporting of anxiety-related work performance strengths, challenges and support measures. METHODS: Thematic analysis was applied to news texts derived from CrossSearch database and internet enquiries and journal articles obtained from Scopus, Medline and Science Direct databases. RESULTS: The analysis of eight news texts …and 36 journal articles produced evidence-based themes including those of work performance strengths (quality, quantity, creativity) challenges (overreaching, perfectionism, overthinking, communication) and support measures (medical, cognitive, physical, flexibility). CONCLUSION: This investigative review reveals that anxiety-related work performance strengths, challenges and support measures as identified within news text reporting of the high functioning anxiety concept have at least some basis in the literature. It might therefore be the case that organizations who invest in supporting employees who identify with high functioning dimensions of their anxiety disorders are the ones who are ultimately rewarded with work performance advantages.

Abstract: Mobile technology has revolutionised how we work. It is now relatively easy to work anywhere and anytime, but this has placed the onus is on mobile (or flexible) workers to set up their own work environment for comfort and ease of use. Vision is an important driver of posture, and hence visual ergonomics principles are integral for setting up digital devices. If mobile workers do not have visual ergonomics knowledge, or are unable to apply visual ergonomics knowledge to appropriately set up their work environment, then they are at risk of developing visual-related occupational health issues due to exposure to …adverse physical work environments. To address this potential health care issue, we propose the introduction of Visual Ergonomics Health Literacy. This would provide mobile workers (including school children) with the knowledge and skills to set up their work environment for comfort and ease of use, wherever they work. It is important to address this issue now before we have a widespread epidemic of discomfort and injury from not applying sound visual ergonomics principles to work environments. Show more

Abstract: BACKGROUND: Given that shift work spreads across many different business sectors, studies of its adverse effects are very topical. Much research has been done on the negative impact of shift work, but many researchers have not focused on its impact in a multicultural environment. OBJECTIVE: The aim of this study was to map out how shift work is perceived by workers in two different shift regimes and two national groups. METHODS: The research was carried out on Czech manufacturing workers and Turkish airport ground personnel using a questionnaire. The impact of shift work was studied from …physical, mental, social and health aspects with connection to family status and gender. For statistical evaluation, Pearson’s chi-squared test of independence was used. The effect of shift work on workers’ performance and scrap rate was analysed only on the sample of the manufacturing workers. RESULTS: Fifty-five Czech male workers, 49 Turkish male workers and 60 Turkish female workers participated in the survey. The dependence between sexes was confirmed for mental aspects and sleeping routines. The main difference between nationalities is in work attitude, social aspects and sleeping routines. According to the family status, the difference was confirmed in all areas except social aspects. The lowest values of productivity and the highest scrap rate were observed on night shifts and the maximum productivity and lowest scrap rates were observed on afternoon shifts. CONCLUSIONS: Some of the basic assumptions were confirmed which suggests that a multicultural environment has an influence on the perception of shift work by the nations and gende. Show more

Abstract: BACKGROUND: The phenomenon of cyberbullying is on the rise among adolescents and in schools. OBJECTIVE: To evaluate the relationship between personality characteristics such as empathy, the tendency to implement cognitive mechanisms aimed at moral disengagement, and the use of social media. PARTICIPANTS: Italian students from first to fifth year in high school classes (n = 264). METHODS: A questionnaire was used to gather information on the sociodemographic characteristics of the participants, their use of social media, their level of empathy (Basic Empathy Scale, BES), and mechanisms of moral disengagement (Moral Disengagement Scale MDS). Two questions …were included to determine whether each participant had ever been a victim of or witness to cyberbullying. RESULTS: Results suggest that offensive behaviors are related to mechanisms of moral disengagement and to interaction using forms of communication that allow anonymity. In addition, offensive behavior appears to be related to forms of Internet addiction, while prosocial behavior is linked with cognitive empathy. CONCLUSION: In order to promote the establishment of prosocial behavior, it would seem necessary for the various players involved – schools, parents, social network developers – to make an effort to implement educational environments and virtual social networks based on a hypothesis of “design for reflection”, educating young people about the need to take the time to understand their feelings and relationships expressed via social media.
