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

This article presents results obtained from some ergonomics intervention in the project for the conception of aircraft's cabins. The study's aim is to analyze the contribution of the method adopted in the passengers' activities analysis in reference situations, real-use situations in aircraft's cabins, applied to analyze typical activities performed by people in their own environment. Within this perspective, the study shows two analyses which highlight the use of electronic device. The first analysis has been registered through a shooting filming in a real commercial flight. In the second one, the use is developed within the domestic environment. The same method has been applied in both contexts and it is based on activity analysis. Starting with the filming activity, postures and actions analysis, self-confrontation interviews, action course reconstruction and elaboration of postures envelopes. The results point out that the developed method might be applied to different contexts, evincing different ways of space occupation to meet human personal needs while performing an activity, which can help us with the anticipation of the users' needs, as well as indicate some innovation possibilities. 相似文献

Subcontracting of specialized functions to external companies (e.g. cleaning or maintenance) is actually very common within several industries. These external companies' are called contractors and their contracting is often designated as outsourcing. Frequently contractors involve other companies (the sub-contractors) to assist them in fulfilling the contract, resulting in a complex chain of organizations focused on interchange of work - the contracting chain. Therefore in the same work site can coexist workers form the client-company and workers from the contractors and/or subcontractors. Since contractors perform their job in client's facilities, they can be exposed to hazards that are unknown to them. On other hand, workers of the client company can also be exposed to hazardous situations derived from the work performed by the contractors. The paper discusses how adequate occupational safety and health conditions can be assured when dealing with this kind of dynamic labor networks. Two case-studies and several examples coming from international literature will be presented. 相似文献

We aimed to evaluate associations between vocational computer use and 1) ulnar neuropathy, and 2) ulnar neuropathy- like symptoms as distinguished by electroneurography. We identified all patients aged 18-65 years, examined at the Department of Neurophysiology on suspicion of ulnar neuropathy, 2001-2007. We mailed a questionnaire to 546 patients with ulnar neuropathy, 633 patients with ulnar neuropathy-like symptoms, and three community referents per case, matched on sex, age, and primary care centre. From a Job Exposure Matrix we extracted estimates of daily hours of computer use. The analysis was performed by conditional logistic regression.There were a negative association between daily hours of computer use and the two outcomes of interest. Participants who reported their elbow to be in contact with their working table for 2 hours or more during the workday had an elevated risk for ulnar neuropathy (OR=2.16, 95 % CI; 1.06-4.44).The two outcomes were not associated with daily hours of computer use. Findings suggested specific effects of pressure on the elbow, and might be an explanation for the overweight of left-sided outcomes in this primarily right-handed group. Preventive efforts would then be straightforward by providing appropriate arm support for the left arm and elbow. 相似文献

In order to achieve better postures and decrease musculoskeletal risks adequate design of hand/box couplings for manual materials handling (MMH) are still needed. No studies evaluating upper limb movement thorough direct measurements during box handling in workplace were identified in the literature. In this study we describe the types of grip and movements adopted by ten workers when handling redesigned boxes with cutout handles between different heights on industrial pallets. The new handles were used by 90% of the workers through different types of grip. Electrogoniometric measurements showed relatively safe forearm and wrist movements, although elbow inadequate range of movement was recorded. Despite the good acceptance of the cutout by workers, the new design requires extra internal space in the boxes reducing applications for this alternative of box. 相似文献

This article presents a study on the inclusion of people with disabilities (mainly mental impairment) in the workforce of a shoe company. The items that could impact on the success of inclusion were identified, and this included employees and other individuals taking part in the process. The inclusion process identified the interests, likes and dislikes of each employee with disabilities and correlated these with the activities available in the company. The case study evaluated the quality of the inclusion through interviews, questionnaires and an assessment of production efficiency. The results showed that inclusion did not adversely affect production, and highlighted that staff with disabilities do their work correctly. According to all employees interviewed, the inclusion of staff with disabilities improved the relationship of the boss with all of the staff and also led to the work environment being enhanced. The final evaluation is that the company's policy of inclusion succeeded. 相似文献

This study streams from a perspective of Workers' Health as a field of intervention where worker's experience on the process of illness is essential to understand and generate changes in the work process, and to contribute to develop knowledge in this area. We intended to collaborate in the training of researchers and nursing workers as a means of contributing to amplify their knowledge related to work and health conditions. As a motto to promote dialogue between researchers and workers, we organized workshops to discuss the results of an epidemiological study on the work-health relationships in nursing. Ten workshops were conducted at two federal public hospitals, in the city of Rio de Janeiro, Brazil. The main aspects discussed during the workshops revealed (i) work nuances for which the questionnaire was not sufficiently sensitive, (ii) some associations between different aspects of the survey, dealt with in the questionnaires, and (iii) recognition that some aspects shown in the epidemiological results were experienced at work. One can appreciate that the proposal presented here contributed to the training of researchers and workers, amplifying their knowledge and contributing to the development of the activity. 相似文献

The paper presents a new approach to the development of cooperative human-machine systems in the Transportation domain which is currently researched in the European project D3CoS. A necessary precondition for the acceptance of cooperative human-machine systems with shared control is the confidence and trust of the user into the system. D3CoS tackles this important issue by addressing the cooperative system as the object and the target of the system development process. This new perspective, along with corresponding innovative methods, techniques and tools, shall allow the identification of optimal task and authority sharing approaches supported by intuitive human-machine interaction and user interfaces at an early stage of system development. This will support powerful teamwork between humans and machines or between machines and machines that is transparent, intuitive and easy to understand. The paper describes the research dimensions for the development of the methods, techniques and tools as well as first results. 相似文献

This article presents the results of a survey carried out on leading periodicals in the areas of Ergonomics, Physiotherapy and Occupational Therapy, the aim of which was to identify scientific publications on the inclusion at work of people with disabilities. The survey of articles published on this topic in the following journals was conducted in December 2010: Applied Ergonomics, Ergonomics, the International Journal of Industrial Ergonomics, Disability and Rehabilitation, and the Journal of Occupational Rehabilitation. The survey covered issues published between 2000 and 2010 and was conducted electronically using the CAPES Periodicals Portal. To collect the articles, it was necessary to check the articles published in each of the issues of each volume of these periodicals. This is how the articles on the topic in question were found. There were 27 articles on the topic of inclusion at work of people with disabilities, of which 13 were published in the Journal of Occupational Rehabilitation and 12 in Disability and Rehabilitation. Thus, it is clear that the issue in question is still a subject that is seldom dealt with in these publications and it is noted that only two articles were published in Ergonomics journals in this period, thus confirming the paucity of scientific publications on this subject. 相似文献

The aim of this paper is to present the results of the evaluation of the job of bricklayer in the construction industry to determine the profile of workers with disabilities who could perform this function and what adjustments are needed. The methods and techniques used in the field study were: direct observation of the activities and the environment, interviews with bricklayers on building sites, a video and photographic record of tasks being carried out to analyze the job of bricklayer, software resources were used. This study set out the disabilities most commonly caused by work accidents in the civil construction industry and simulated the conditions of the individuals to determine whether they could perform the activities of this function and what adaptations are needed. It was observed that workers with hearing impairments could perform activities without any change in the workplace and individuals who had had a leg or foot amputated need to use appropriate prostheses to perform the activities of the function. Thus, it was shown that the activity of professionals with experience in Ergonomics is essential since, by the activity of gathering data and analysing the physical, cognitive and organizational requirements of jobs and by collecting data on and analysing the functional capabilities of the worker with a disability, adaptations to jobs can be adequately defined. 相似文献
