Dixon and Johnson (Anal Gambl Behav 1: 44–49, 2007) proposed the Gambling Functional Assessment as a tool to identify the consequences maintaining the respondent’s gambling behavior, but subsequent studies on its psychometric properties suggested that it could use improvement. The present study investigated the internal consistency of the Gambling Functional Assessment—Revised using the responses of 1,060 undergraduate students. Temporal reliability was assessed by a second administration of the measure four (n = 87) or twelve (n = 98) weeks after the first administration. Temporal reliability was also compared to the South Oaks Gambling Screen (Lesieur and Blume in Am J Psychiatry 144: 1184–1188, 1987), which was also administered at both time points. Internal consistency measures were good to excellent, even when potential non-gamblers were excluded from the analyses. Temporal stability was also very good, with the possible exception of the consequence of “escape” at 12 weeks. The Gambling Functional Assessment—Revised represents a potentially useful tool for researchers and therapists interested in why respondents are gambling.  相似文献

This work studies biomechanical hazards to which the workforce of Instituto Nacional de Metrologia, Qualidade e Tecnologia Industrial (Inmetro) is exposed. It suggests a model for ergonomic evaluation of work, based on the concepts of resilience engineering which take into consideration the institute's ability to manage risk and deal with its consequences. Methodology includes the stages of identification, inventory, analysis, and risk management. Diagnosis of the workplace uses as parameters the minimal criteria stated in Brazilian legislation. The approach has several prospectives and encompasses the points of view of public management, safety engineering, physical therapy and ergonomics-oriented design. The suggested solution integrates all aspects of the problem: biological, psychological, sociological and organizational. Results obtained from a pilot Project allow to build a significant sample of Inmetro's workforce, identifying problems and validating the methodology employed as a tool to be applied to the whole institution. Finally, this work intends to draw risk maps and support goals and methods based on resiliency engineering to assess environmental and ergonomic risk management.  相似文献

Objective: Social firms or enterprises aim to offer sustainable employment in supportive workplaces for people who are disadvantaged in the labour market. Therefore, this study sought to explore employees' views in one social firm about the features of their workplace that they found supportive.Participants: Seven employees were recruited, all of whom experienced persistent mental illness, and had worked in this social firm for between eleven months and six years. Methods: A semi-structured interview, the Work Environment Impact Scale (version 2.0), was used to explore participants' views of their workplace and to rate how its physical and social characteristics impacted them. Participants also rated their job satisfaction with a modified Indiana Job Satisfaction Scale. Results: Features of the social firm workplace identified by these employees as contributing to their sustained employment and satisfaction were the rewards, task demands, work schedule, and workplace interactions with supervisors and other co-workers. From their views, guiding principles for the development of supportive workplaces and evaluation of their capacity to afford sustainable employment were derived. Conclusions: This study adds to current knowledge about workplace supports from an employee perspective, and is of relevance for informing future social firm development, workplace design and evaluation.  相似文献

A major barrier to employment for people with mental illness is limited access to supportive and non-discriminatory workplaces. Social firms are businesses committed to employing up to 50% of people with a disability or other disadvantage and to providing supportive work environments that benefit workers. Little research has been conducted to understand the features and social processes that support the vocational experiences of employees with mental health issues in social firms. Objective: This ethnographic study sought to explore the experiences of nine employees at one Australian social firm. Participants: Nine employees of a social firm, with and without mental illness. Methods: Study methods used included participant observation, interviewing and document analysis. Results and conclusions: The study highlights the complexity of running a socially-invested business, and the importance of cross-sectoral partnerships to support their operational success. Natural workplace supports, adequate training and support infrastructure and enabling participation in the business, were identified as important to creating a supportive workplace. Partnerships within the workplace and in support of the workplace are discussed. Future growth and development of partnerships are recommended to support the establishment of social firms.  相似文献

The number of occupational diseases in Mexico is alarming and clearly it is important to do studies with the purpose of improving the design of workstations. The objective of this research is to determine the maximum force levels in different positions of shoulder and elbow. An experiment was conducted with 16 subjects between 18 and 28 years old: 8 male and 8 female. We considered 16 different positions, working with the right and left arm to perform the tasks of pull and push. The tasks consisted of pushing or pulling a dynamometer for a period of 3 seconds as hard as possible. The results were presented in tables. The tables show the mean, standard deviation and range of force levels in different positions.  相似文献

The operating microscopes may be a significant cause of fatigue and discomfort in surgeons. The need for the microscope to be placed over the operating field forces surgeons to remain at the microscope's eyepieces at an uncomfortable posture for the entirety of the surgery. This study compared the effects on microsurgical task performance for four visualization methods: a monocular microscope, a binocular microscope, a three-dimensional (3D) flat-panel television display and a two-dimensional (2D) flat-panel television display. Eleven subjects each performed two microsurgical tasks and their performance was documented by video camera. The statistical analysis performed indicated utilization of the microscope as a visualization method increased subject performance. No significant difference in performance between the 2D and stereoscopic visualization methods.  相似文献
