OBJECTIVE To investigate the feasibility, costs and sample representativeness of a recruitment method that used workers with back injuries as the point of entry into diverse working environments. METHODS Workers' compensation claims were used to randomly sample workers from five heavy industries and to recruit their employers for ergonomic assessments of the injured worker and up to 2 co-work...

Psychologists have consistently documented people’s tendency to be overconfident about their own ability. We interpret workers’ confidence in their own skills as their morale, and investigate the implication of worker overconfidence on the firm’s optimal wage-setting policies. In our model, a wage contract both provides incentives and conveys to the worker the firm’s opinion about her ability, ...

BACKGROUND In the rapid scale-up of human immunodeficiency virus (HIV) care and acquired immunodeficiency syndrome (AIDS) treatment, many donors have chosen to channel their funds to non-governmental organizations and other private partners rather than public sector systems. This approach has reinforced a private sector, vertical approach to addressing the HIV epidemic. As progress on stemming ...

BACKGROUND Non-suicidal self-injury (NSSI) disproportionally affects Indigenous Australians. Friends, family and frontline workers (for example, teachers, youth workers) are often best positioned to provide initial assistance if someone is engaging in NSSI. Culturally appropriate expert consensus guidelines on how to provide mental health first aid to Australian Aboriginal and Torres Strait Isl...

OBJECTIVE The purpose of this study was to examine the difference between self-reported hearing status and hearing impairment assessed using conventional audiometry. The associated factors were examined when a concordance between self-reported hearing and audiometric measures was lacking. METHODS In total, 19,642 individuals ≥20 years of age who participated in the Korea National Health and N...

background: teaching of theoretical and practical first aids are  important courses for medical sciences students. if these courses are  taught with evidence based medicine(ebm), they will be learned better by students. the objective of this study  was the  determination of the  effect of evidence based medical education on learning of first aids. methods: this study had been performed inthe pl...

Mobile manipulation capabilities are key to many new applications of robotics in space, underwater, construction, and service environments. This paper discusses the development of robotic "assistance" capabilities to aid workers in the accomplishment of a variety of physical operations and presents various control strategies developed for vehicle-arm coordination, compliant motion tasks, and co...

The problem of prediction of finite temperature properties of materials poses great computational challenges. The computational treatment of the multitude of length and time scales involved in determining macroscopic properties has been attempted by several workers with varying degrees of success. This paper will review the recently developed quasicontinuum method which is an attempt to bridge ...

We have determined the nucleotide sequence of the rat hprt (hypoxanthine phosphoribosyltransferase; EC 2.4.2.8.) mRNA coding region and of adjacent, untranslated 5' and 3' mRNA, and we have designed an oligonucleotide primer pair for efficient PCR amplification of the rat hprt coding region. These sequence data and rat-specific primer pair will aid workers interested in coupling well-developed ...

We Americans believe that there is basically one rational way to live: ours. There is one legitimate path of development, which leads toward democracy, transparency, and a competitive market system. Our dealings with the rest of the world are based on this assumption. We reinforce the point by dispatching economists, foreign aid workers, and religious missionaries to teach the world how to live...
