The meanings attached to “race” across the globe are myriad, particularly as anti‐Islamic discourse once again links race and religion. Yet scholars lack a common terminology to discuss this phenomenon. This article hopes to expand critical race theory and scholarship across national lines. This critical examination of recent race‐related scholarship provides scholars with empirical suggestions to uncover and document the different processes, mechanisms, trajectories and outcomes of potentially racialized practices that essentialize, dehumanize, “other,” and oppress minority groups while imbuing privileged groups with power and resources in nations across the globe. Ten empirical indicators will allow international researchers to assess the particular situation of different groups in different nations to determine whether, and the extent to which, they are subject to racialization. Specifically, this paper calls for a unified terminology that can accurately account for and address race when and where it occurs and a global broadening of a critical comparative dialogue of racial practices.  相似文献

This paper presents an assessment with simulated activities with the aim of analyzing the perception of ease / difficulty of the use of faucets (taps) handles by 180 Brazilian adults. Five different handles faucets were activated for subsequent collection of perceptual data. The procedures were based on main recommendations for biomedical ethics and human research. The results indicate that handles with levers are significantly (p ≤ 0.05) easier to use. The most difficult are characterized by not having support points for the rotation (levers) or more points of pressure concentration in the hand.  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 current paper presents the study of organizational stressors survey carried out in a military institute, responsible for researches of high demand on aerospace technology. The study considered the theoretical framework of Organizational Ergonomics, combined with the technical guidelines of Psychology applied to Work Safety. The participatory approach was used on daily work assessment and decision making, aiming the adoption of corrective and preventive measures, considering possible distortions and imbalances between prescribed and actual activities. Thus, it was sought to engage and encourage the participation of the Institute's workers in the reflection/creation of better solutions to daily problems and to achieve productivity, without prejudice in the occupational health and safety.  相似文献

Ergonomics and accessibility in banking has been the subject of numerous discussions, and in this work proposed by the partnership of companies and NR TN Mobile Work Safety and Occupational Medicine, aimed to analyze the service box and propose the development of a project to the teller accessible account of both the legal aspects regarding the factors inherent in banking, focusing primarily on the interface of the worker and the client user.  相似文献

Based on a new model of productivity in age diverse tams, findings from a six-year research program are reported in which data from more than 745 natural teams with 8,848 employees in three different fields (car production, administrative work, financial services) were collected. Moreover, central assumptions of this model were tested with a representative survey of the German workforce (N = 2,000). Results support both significant advantages and disadvantages for age-mixed teams. Based on the findings, the following preconditions for the effectiveness of age diverse teams are identified: high task complexity, low salience and high appreciation of age diversity, a positive team climate, low age-discrimination, ergonomic design of work places, and the use of age differentiated leadership. Based on these insights, we developed a new training for supervisors, which addresses the aforementioned aspects and seeks to improve team performance and health of team members. It was found that the training reduces age stereotypes, team conflicts and enhances innovation. Thus, we can conclude that effective interventions for a successful integration of elderly employees in work groups are available and that combinations of measures that address ergonomic design issues, team composition and leadership are to be strongly recommended for practice.  相似文献

Into dangerous and complex systems with high degree of interactivity between its components, the variability is present at all time, demanding a high degree of control of its operation. Maintaining or recovering the normality, when the system is under some stress (instability) is a function of Resilience. To cope with prevention, forecast, recovery and with memory of experiences from learned lessons requires some features from the companies. This paper purposes a structure that enables the Total Resilience of a system production that defines the assignments for Workers, Designers and Management Team, according to its features and possibilities. During one year and a half developing studies on ergonomics area of a Brazilian Oil Refinery, several situations were observed and studied using Work Ergonomic Analysis. These situations show actions and strategies that workers use to maintain the system stability. Furthermore, they revealed the importance that these actions are stored in a database of learned lessons from the Company. The research resulted in a broad scheme. It places each of these groups in the process of Total Resilience. It also shows the human like a center of actions that ensure the continuity of the system, main element at Resilience (Anthropocentric View).  相似文献

Training and provision of assistive devices are considered major interventions to prevent and treat low back pain (LBP) among workers exposed to manual material handling (MMH). To establish the effectiveness of training and provision of assistive devices in preventing and treating LBP an update of a Cochrane literature review was performed to November 2010. Randomised controlled trials (RCTs) and cohort studies with a concurrent control group (CCTs) were included. Nine RCTs (20.101 employees) and nine CCTs (1280 employees) were included for prevention: six more than in the previous version. No study on treatment was found. None of the included RCTs and CCTs provided evidence that training and provision of assistive devices prevented LBP when compared to no intervention or another intervention.  相似文献
