The frequency of occupational accidents in fishery is high in most fishery nations. Implementation of safety measures has, however, been limited. The purpose of the present cross-sectional study was to explore Swedish fishermen's attitudes towards occupational risks and accident control. Information was acquired through a questionnaire distributed to a convenience sample of 92 fishermen. Indices were built, containing variables relevant to perceived risk levels in connection with work, perceived manageability of risks, activity in safety work, technical knowledge and individual attitudes towards risks. The results did not support earlier findings of low risk awareness and risk acceptance among fishermen. Perceived manageability of risks but not perceived risk level, accident experience or risk acceptance, were significantly associated with activity in safety work. The results suggest that safety work might benefit from efforts to develop fishermen's understanding of how the development of hazardous situations can be prevented or managed. The results do not support strategies for accident control in fishery based solely on increasing risk awareness.  相似文献

Child and family practice is recognised as a field of social work that has become increasingly complex. While evidence is growing in relation to effective supervision, there has been little research about the attributes of an effective supervisor, or the components of effective supervision. This paper reports on research undertaken in Victoria, Australia, which explored practitioners’ and supervisors’ experiences of effective supervision in this field. Data collection involved in-depth interviews with experienced supervisors and supervisees in order to explore the concept of effective supervision from participants’ perspectives. The data were systematically interrogated using a thematic inductive process, designed to enhance the voice of participants in the research. The study findings confirmed the complexity and centrality of the supervisory relationship, with the experience of a safe supervisory relationship proving essential. The importance of contemporary knowledge, leadership skills, and an enabling organisational and community context were also highlighted.  相似文献

在风险社会下,食品安全不仅关系着广大人民群众的身体健康和生命安全,还影响着经济发展与社会稳定。而我国目前,由于食品安全规制建设起步较晚,其在基础性法律规范制定、安全标准的科学性与体系化、行政管理体制等方面还存在诸多问题。因此,健全食品安全标准体系,建立高效的食品安全管理体制,引入食品安全风险分析制度,完善食品安全规制的法律体系,势必成为今后我国食品安全规制改革的重中之重。  相似文献

Manufacturing process improvement teams often draw upon cross‐functional expertise. However, teams dominated by a single or few functions often do not achieve the desired interdisciplinary learning and cooperation, which in turn could negatively affect the performance of that cross‐functional team. Through an empirical analysis of 149 manufacturing process improvement teams in six SIC industrial categories, we show that even after controlling for several factors such as team size, number of functions, gender diversity, ethnicity, number of management levels, and geographic dispersion of team members, psychological safety of work environment fully mediates the relationship between functional dominance and team performance. We also confirm that a team leader possessing high interpersonal justice mitigates the deficiency of dominated teams and improves team performance by fostering a psychologically safe work environment. Our recommendation therefore is that when a dominated team is unavoidable due to the needed skill sets or other organizational considerations, to ensure success it is imperative that the firm chooses a team leader who can promote psychological safety by being just, and who can effectively encourage input from all functional team members and give them objective feedback.  相似文献

The structure of employee attitudes to safety: A European example   总被引:1,自引:0,他引:1  
This paper concerns organizational safety culture and the structure or architecture of employee attitudes to safety as part of that culture. It begins by reviewing the somewhat scant literature relevant to this area, and then reports a study, conducted in a European company, which collected and factor analysed data on employee attitudes to safety. The framework provided for the study was that offered by Purdham (1984), and the results suggested that employees' attitudes to safety, within this company (across occupation/occupational level and country), could be mapped By five orthogonal factors: personal scepticism, individual responsibility, the safeness of the work environment, the effectiveness of arrangements for safety, and personal immunity. The theoretical and practical implications of these findings are discussed, and attention is drawn to their subsequent use in an intervention to enhance safety culture within the organization by attacking supervisors' attitudes to safety.  相似文献

Fatality reductions from increases in safety belt use are estimated taking into account that drivers who change from being nonusers to being users have lower accident involvement rates than the remaining nonusers, a process referred to as "selective recruitment." Analytical functions are derived which express expected fatality reductions in terms of changes in safety belt use rates from an initial rate. The function parameters are determined by requiring that computed average crash rates for nonusers be 53% higher than the rates for users, a recently determined empirical value. These functions show that, depending on the initial use rate and use rate increase, selective recruitment may increase or decrease expected fatality reductions. However, effects are relatively small, in no case exceeding +/- 5.3%.  相似文献

Quantitative risk assessment (QRA) models are used to estimate the risks of transporting dangerous goods and to assess the merits of introducing alternative risk reduction measures for different transportation scenarios and assumptions. A comprehensive QRA model recently was developed in Europe for application to road tunnels. This model can assess the merits of a limited number of "native safety measures." In this article, we introduce a procedure for extending its scope to include the treatment of a number of important "nonnative safety measures" of interest to tunnel operators and decisionmakers. Nonnative safety measures were not included in the original model specification. The suggested procedure makes use of expert judgment and Monte Carlo simulation methods to model uncertainty in the revised risk estimates. The results of a case study application are presented that involve the risks of transporting a given volume of flammable liquid through a 10-km road tunnel.  相似文献

The economically optimal sample size in a food safety test balances the marginal costs and marginal benefits of increasing the sample size. We provide a method for selecting the sample size when testing beef trim for Escherichia coli O157:H7 that equates the averted costs of recalls and health damages from contaminated meats sold to consumers with the increased costs of testing while allowing for uncertainty about the underlying prevalence rates of contamination. Using simulations, we show that, in most cases, the optimal sample size is larger than the current sample size of 60 and, in some cases, it exceeds 120. Moreover, lots with a lower prevalence rate have a higher expected damage because contamination is more difficult to detect. Our simulations indicate that these lots have a higher optimal sampling rate.  相似文献
