This paper compares the ergonomic risk assessment of a task for the upper extremities as determined by Rapid Upper Extremity Assessment (RULA) and the Strain Index (SI). The ergonomic risk to the upper extremities of 244 automotive assembly plant tasks were evaluated using RULA and SI. The outcomes of each tool were compared for each task. Results from this study provide practical insight into the methods used in each tool. This study compared only the ergonomic risk outputs from each tool; it does not pursue the question of which tool best predicts injury. The kappa score was 0.11, indicating little agreement between the outputs of the two tools. This is supported by the lack of monotonicity with a gamma score of 0.1. These results indicate that the risk assessment outcome of these two ergonomic assessment tools for the upper extremities do not agree. 相似文献

Although they have a recent work history, 70 to 80% of adults with multiple sclerosis are unemployed following their diagnosis. This high rate of unemployment constitutes a great loss of potential to the American economy. To help individuals with multiple sclerosis (MS) return to work or retain employment, rehabilitation professionals must understand the barriers resulting in unemployment and implement interventions to reduce or remove those concerns. In this article, Hershenson's systemic model of rehabilitation counseling is presented as a diagnostic scheme for identifying barriers to employment. Counselor consultation on barrier removal via reasonable accommodation is presented as one example of a rehabilitation intervention consistent with the systemic diagnostic model. 相似文献

The present study tested the theory that negative affect and one’s ability to tolerate distress is associated with failure
to quit gambling during an abstinence attempt. Specifically, 16 current pathological gamblers who had at least one sustained
period of gambling abstinence lasting a minimum of 3 months (i.e., delayed relapsers) and 16 current pathological gamblers
who had never remained abstinent for a period longer than 2 weeks (i.e., immediate relapsers), were assessed for baseline
levels of negative affect and stress reactivity, as well as faced with a psychological (mental arithmetic) and physical (breath
holding) stressor. Compared to the delayed relapsers, the immediate relapsers displayed higher levels of negative affect and
stress reactivity. Immediate relapsers also were less likely to persist on the psychological stressor, suggesting that one’s
ability to tolerate the initial discomfort of an abstinence attempt may play an important role in gambling treatment outcome.
The current project was completed in partial completion of the degree of Master of Arts in Psychology by the first author
under the direction of the second author. 相似文献

Risk Factors in Adolescence: The Case of Gambling, Videogame Playing, and the Internet 总被引:4,自引:1,他引:3
Griffiths M Wood RT 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2000,16(2-3):199-225
It has been noted that adolescents may be more susceptible to pathological gambling. Not only is it usually illegal, but it appears to be related to high levels of problem gambling and other delinquent activities such as illicit drug taking and alcohol abuse. This paper examines risk factors not only in adolescent gambling but also in videogame playing (which shares many similarities with gambling). There appear to be three main forms of adolescent gambling that have been widely researched. Adolescent gambling activities and general risk factors in adolescent gambling are provided. As well, the influence of technology on adolescents in the form of both videogames and the Internet are examined. It is argued that technologically advanced forms of gambling may be highly appealing to adolescents. 相似文献

不确定性在团队授权与新产品开发业绩关系中的作用 总被引:1,自引:0,他引:1
一个最新的理论研究表明授权的作用取决于环境中不确定性的程度。在对212个新产品开发项目的定量研究中,发现了团队授权与创新速度之间显著性相关关系。对由技术新颖性和技术动态性这两个不同因素引起的技术不确定性作了区分。结果发现,团队授权和创新速度之间的关系被技术动态性所调节,而技术新颖性则不能。通过进一步的研究发现,在不确定性较低的情况下,无论来源于技术新颖性或技术动态性,团队授权和创新速度均呈U形函数关系。这说明在不确定性较低的情况下,要么完全授权,要么完全不授权或高层介入,都有利于提高创新速度。与之形成对应,在不确定性高的情况下,团队授权和创新速度之间的关系受技术新颖性和技术动态性的影响是不同的。当技术新颖性高时,团队授权和创新速度之间呈线性关系,而当技术动态性高时,二者呈反U形函数关系。对于后者,极高程度的团队授权并不加快创新速度。这些结果说明,应该根据研发项目的不确定性的不同来源与水平选择不同的团队授权策略。这些发现或许也表明,技术动态性比技术新颖性对不确定性有更重要的影响。 相似文献

A conceptual framework is presented for conducting exposure assessments under the U.S. EPA's Voluntary Children's Chemical Evaluation Program (VCCEP). The VCCEP is a voluntary program whereby companies that manufacture chemicals of potential concern are asked to conduct hazard, exposure, and risk assessments for the chemicals. The VCCEP is unique in its risk-based, tiered approach, and because it focuses on children and requires a comprehensive consideration of all reasonably foreseeable exposure pathways for a particular chemical. The consideration of all potential exposure pathways for some commonly used chemicals presents a daunting challenge for the exposure assessor. This article presents a framework for managing this complicated process, and illustrates the application of the framework with a hypothetical case study. The framework provides guidance for interpreting multiple sources of exposure information and developing a plausible list of exposure pathways for a chemical. Furthermore, the framework provides a means to process all the available information to eliminate pathways of negligible concern from consideration. Finally, the framework provides guidance for utilizing the tiered approach of VCCEP to efficiently conduct an assessment by first using simple, screening-level approaches and then, if necessary, using more complex, refined exposure assessment methods. The case study provides an illustration of the major concepts. 相似文献
