The aim of the present study is to contribute to the analysis of employment and work conditions of Portuguese trainers, as well as to identify conditions, resources, demands and constraints of their work activities. Despite the lack of scientific knowledge on professional training, the topic has been playing a central role in modern societies. Several data collection strategies were used, namely the application of INSAT to 72 trainers, exploratory interviews with 10 trainers and collective interviews with 6 trainers. The analysis of the data collected highlights the changes in the selection of human resources in the sector as well as the contractual terms of the trainers, mainly independent workers. The intra and inter individual variability of working hours and the diversity of activities performed by each trainer also stands out. Finally, it is important to refer the spontaneous organization of trainers' work activities according to their training modality.  相似文献

The generation growing and diversified of Municipal Solid Waste is configured as an environmental problem, economic and social deterioration, especially, by application of inappropriate management of them. Faced with this urban context, the research in development presents as specific objective assessment of the quality of life of the gatherers of recyclable materials were active in the city of Juiz de Fora, in the brazilian state of Minas Gerais. In addition, the objective is, still, the recognition of the activity of sorting performed by "scavengers" in order to maximize the reduction, reuse and recycling energy and material waste daily. The proposed methodology is based on the application of the questionnaire Word Health Organization Quality of Life (WHOQOL-100), prepared by the World Health Organization, in order to value the quality of life of the gatherers of recyclable materials, involved, even in educational workshops in order to discuss and organize strategies of health care and scouting to the basement to public policies.  相似文献

Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical base comes from a project assessing organizational learning and the effectiveness of the different steps of the learning cycle for safety and studying relations between safety-specific transformational leadership, safety climate, trust, safety-related behavior and learning from incidents. The results point at common weaknesses in the organizational learning, both in the horizontal learning (geographical spread) and in vertical learning (double-loop learning). Furthermore, the effectiveness in the different steps of the learning cycle is low due to insufficient information in incident reports, very shallow analyses of reports, decisions that focus at solving the problem only at the place where the incident took place, late implementations and weak solutions. Strong correlations with learning from incidents were found for all safety climate variables as well as for safety-related behaviors and trust. The relationships were very strong for trust, safety knowledge, safety participation and safety compliance.  相似文献

To be able to disseminate knowledge about maritime safety culture and safety management to different actors in the Swedish maritime sector, a preliminary pedagogical concept was developed and evaluated. As a first user group, students at upper secondary maritime schools were chosen and the pedagogical concept was adapted for this group. The concept includes an interactive prototype and a teacher's guide and is based on a model for experience-based learning which connects theory and practice by a cyclic approach. The concept was tested in a classroom setting including interaction with the students and a follow-up one week later. A preliminary evaluation of the results shows a very positive response among the students as well as the lecturers. The educational material was successful in immediately creating a relevant discussion about safety culture, and one week later, students could remember many of the safety scenarios included in the pedagogical concept.  相似文献

Citizens are increasingly called upon to comment on issues that directly concern them. However, such consultations may be tokenistic [1] as they occur with limited respondents, or may be at a time, or in a format which is inconvenient to the user. To encourage wider participation, the VoiceYourView project (vYv) has developed a system allowing people to make comments in a manner, time and place convenient to them. A real world trial of the prototype system was conducted at Coventry University campus to explore issues related to the system's usability and usage, as a means of enabling campus users to comment on their environment. Members of the university population were invited to comment on the university estate using one of five technologies (e-mail, online form, iPhone app, SMS message, or electronic kiosk). Although the immediate application area in this case was the design of public spaces, the approach can be transferred to other domains and thus provide a new way of gathering user information. Submitted comments were automatically analysed in terms of theme, sentiment, location and actionability and displayed online in a 2D visualisation. It is argued that that online data collection (crowd sourcing and skimming social networks) may provide a rich source of information for future ergonomists.  相似文献
