When suspects were unidentified, victims were more likely to have consumed alcohol prior to assault, and reporting the suspect being of non-Western origin. Also, the reporting of a public venue was more frequent when unidentified suspect. CONCLUSIONS The study shows different patterns in groups of suspects as to victim and assault characteristics. Detection and description of such differences can provide valuable information for future prevention programs, police investigation methods and health care guidelines. BACKGROUND Due to the demographic challenge in most countries it is important to consider making work life sustainable. A sustainable work life is of importance in all age groups when working life will be extended to a higher age. AIM Towards a theoretical model with an impact on a sustainable working life for all ages, the swAge - model. METHOD The theoretical model, the swAge-model, is developed based on grounded theory using qualitative studies, quantitative studies, intervention projects and literature reviews. RESULT The swAge-model states the interactions between different ageing concepts; chronological, mental, biological and social ageing, and the nine areas of importance for individuals' work life participation. The model also states the four consideration areas whether individuals can and want to participate in an extended working life or not. The model also includes proposed measures at the organisation/enterprise level and at the society level based on the four activity areas at the individual level. CONCLUSION The theoretical swAge-model describes how to reflect on working life and presents tools to extend work life in a sustainable way for older workers in modern society. The swAge-models' analysis and measure matrix is included as appendix 1. In the Nordic countries the theoretical model is use in the critical debate and as a tool for managers and authorities to make the working life sustainable for all ages. Systems contradictions present challenges that need to be effectively managed, e.g. due to conflicting rules and advice, goal conflicts, and mismatches between demand and capacity. We apply FRAM (Functional Resonance Analysis Method) to intravenous infusion practices in an intensive care unit (ICU) to explore how tensions and contradictions are managed by people. A multi-disciplinary team including individuals from nursing, medical, pharmacy, safety, IT and human factors backgrounds contributed to this analysis. A FRAM model investigation resulting in seven functional areas are described. A tabular analysis highlights significant areas of performance variability, e.g. administering medication before a prescription, prioritising drugs, different degrees of double checking and using sites showing early signs of infection for intravenous access. Our FRAM analysis has been non-normative performance variability is not necessarily wanted or unwanted, it is merely necessary where system contradictions cannot be easily resolved and so adaptive capacity is required to cope. Health information technology (IT) implementation has encompassed much of the United States health care system over the past decade, and user frustration with health IT has steadily increased. Human factors and ergonomics (HFE) methods and approaches can improve the design, implementation, and use of health IT for clinicians and consumers. To better understand the effect of federal HFE in health IT research funding, the authors conducted a review of several key, specific initiatives. The review focused on the goals and accomplishments of these initiatives. Findings to date show that HFE is improving the usefulness of health IT, but additional research and new methods are needed. Corresponding research funding and policy priorities are identified. New HFE work and innovative approaches are needed to capitalize on HFE knowledge, principles, and methods to improve the design, implementation, and use of health IT at a broader scale. Published by Elsevier Ltd.Women experience higher prevalence of work-related upper limb musculoskeletal disorders compared to men. Previous studies have investigated the biological, kinematic and electromyographic sex-related differences during a lifting task but the actual differences in musculoskeletal loads remain unknown. We investigated the sex differences in three musculoskeletal indicators the sum of muscle activations, the sum of muscle forces and the relative time spent beyond a shear-compression dislocation ratio. A musculoskeletal model was scaled on 20 women and 20 men lifting a 6 or 12kg box from hip to eye level. Women generated more muscle forces and activations than men, regardless of the lifted mass. Those differences occurred when the box was above shoulder level. In addition, women might spend more time beyond a shear-compression dislocation ratio. Our work suggests higher musculoskeletal loads among women compared to men during a lifting task, which could be the result of poor technique and strength difference. Heat generated in electronic devices is generally unevenly distributed across the casing. Contacting the hot areas may cause thermal discomfort and possibly skin burn. This study aims at better understanding the interrelationship between the thermal sensation, material properties and surface temperature for enhancing the user experience of electronic devices. A Thermal Simulation System was developed in this study to precisely control the surface temperature of shell materials to simulate various end-use conditions. Seventeen participants were asked to contact the plates with their fingers and rate their thermal sensation using the magnitude estimation approach. Results showed that thermal sensation magnitude and plate temperature followed a power function. TAS-102 purchase The differences in sensation magnitude can be attributed to the thermal inertias of different materials. The findings suggested that laminated plate was generally perceived cooler when heated. Given that the surface temperature of plate is higher than skin, the thermal sensation magnitude increases with contact duration. Occupants of autonomous vehicle have frequently indicated the desire to sleep or rest while driving, yet little has been known regarding the suitable design criteria for a biomechanically reasoned in-vehicle sleeping position. This study was aimed at evaluating the biomechanical quality of different backrest and seat pan angle combinations, and at predicting the most favourable sleeping positions based on vehicle restriction. More specifically, the interface pressure distribution and subjective suitability rating of 23 subjects was assessed in a total of nine (3 × 3) combinations of seat pan (20°, 30°, 40°) and backrest (145°, 155°, 165°) angles. Biomechanical quality was evaluated with an interface pressure score (IPS) based on sensitivity weighted pressures and the total contact area. Two-way repeated measures ANOVA revealed that IPS significantly improves with increasing seat pan angle whereas backrest angles of 155° or 165° lead to significant better IPS compared to flatter ones (145°). The overall highest IPS was observed for a 40°-seat pan angle in combination with a 155°-backrest angle.
