What Determines Trust in Information About Food-Related Risks? Underlying Psychological Constructs 总被引:12,自引:0,他引:12
Trust in risk information about food related-hazards may be an important determinant of public reactions to risk information. One of the central questions addressed by the risk communication literature is why some individuals and organizations are trusted as sources of risk information and others are not. Industry and government often lack public trust, whereas other sources (for example, consumer organizations, the quality media, medical doctors) are highly trusted. Problematically, previous surveys and questionnaire studies have utilized questions generated by the investigators themselves to assess public perceptions of trust in different sources. Furthermore, no account of the hazard domain was made. In the first study reported here, semistructured interviewing was used to elicit underpinning constructs determining trust and distrust in different sources providing food-related risk information ( n = 35). In the second study, the repertory grid method was used to elicit the terminology that respondents use to distinguish between different potential food-related information sources ( n = 35), the data being submitted to generalised Procrustes analysis. The results of the two studies were combined and validated in survey research ( n = 888) where factor analysis indicated that knowledge in itself does not lead to trust, but that trusted sources are seen to be characterised by multiple positive attributes. Contrary to previous research, complete freedom does not lead to trust—rather sources which possess moderate accountability are seen to be the most trusted. 相似文献

Mlonte Carlo Techniques for Quantitative Uncertainty Analysis in Public Health Risk Assessments 总被引:2,自引:0,他引:2
Most public health risk assessments assume and combine a series of average, conservative, and worst-case values to derive a conservative point estimate of risk. This procedure has major limitations. This paper demonstrates a new methodology for extended uncertainty analyses in public health risk assessments using Monte Carlo techniques. The extended method begins as do some conventional methods--with the preparation of a spreadsheet to estimate exposure and risk. This method, however, continues by modeling key inputs as random variables described by probability density functions (PDFs). Overall, the technique provides a quantitative way to estimate the probability distributions for exposure and health risks within the validity of the model used. As an example, this paper presents a simplified case study for children playing in soils contaminated with benzene and benzo(a)pyrene (BaP). 相似文献

AbstractAs economies become more reliant on innovative, knowledge-intensive firms, understanding the interaction between knowledge and improving innovation performance is increasingly important. Although most UK businesses are micro, small or medium-sized enterprises (micro/SMEs), knowledge management research has tended to focus on large companies Knowledge sharing can be critical for innovation performance, especially for smaller players with limited resources. Our study presents an insight from micro/SMEs operating in the highly knowledge-intensive and innovative games/entertainment software development sector. Using a mixed method approach, we investigate knowledge sharing and its contribution to firm innovation performance improvements. Our findings suggest that micro/SMEs are at the forefront of the creative sector precisely because of their smaller size. Our study reveals evidence of knowledge donation but limited evidence of knowledge collection in the knowledge sharing process. We develop a model highlighting the importance of industry context, individual knowledge and organizational size in knowledge sharing for innovation performance. 相似文献

Given the global changes in how work is conceptualized, organized and performed [8], it is critical that graduating occupational therapists have an up-to-date knowledge of work and work practice. This article briefly explores the relative dearth of work practice courses in current occupational therapy curricula and presents the rationale for developing a model for teaching and learning about occupational therapy work practice. It introduces a client-centered and occupation-focused model developed for an undergraduate work practice course and describes the use of the model in a specific course. The model identifies eight common work-related areas of concern - values clarification, vocational exploration, vocational choice, job search, starting work, maintaining work, returning to work and leaving work. Occupational Therapy tools, techniques and programs which may be useful in addressing these concerns; and the environmental factors that influence therapist and client in addressing work issues are also part of the model. The article concludes with examples of topics and issues which could be explored using this teaching and learning model. 相似文献

The article describes the technology transfer concerns reported by a small sample (N=14) of recent college graduates with disabilities. In structured, in-depth interviews, researchers asked respondents to reflect on the extent to which they had utilized technology resources during their college years in preparation for the world of work. Results suggest that colleges and universities need to play a more active role in introducing students with disabilities to both generalized and assistive technology services. 相似文献

This paper shows that financial intermediation can influence fertility and labor allocation decisions by raising market wages.
The increase in wages induces some households to abandon “traditional” labor intensive methods of production managed at the
household level and supply labor to “modern” sector firms. Since it is optimal for households in the modern sector to have
fewer children, the labor allocation decision leads to lower national fertility. A panel VAR using financial intermediation,
fertility and industrial employment share data in 87 countries is estimated. The empirical results show that the data are
consistent with the theoretical predictions.

As a result of the ongoing hallucinations and delusions, life at home became "anxious and chaotic" with "lots of stress." Because there was no on-site crisis intervention by professionals, well siblings were sometimes called upon to control the violent behavior and were vigilant and fearful regarding the potential for abuse. Negative symptoms were the most disturbing to well siblings. Siblings need help to understand that social isolation and lack of motivation are symptoms of the illness--not due to "laziness." 相似文献

Today, interest in defining the role of the physician executive and ensuring this individual is effectively integrated into the organization is high for good reason--the ranks of physician executives are growing. What attributes should health care organizations look for when hiring physician executives and what should they should expect of them once they are on the job? Physician executives should: (1) have demonstrated clinical and management skills; (2) have a comfort level with participatory decision-making; (3) have superb interpersonal skills; and (4) be a champion of the patient. Physician executives should expect the following support from their organizations: (1) varied roles and responsibilities; (2) mentoring by other senior executives; (3) lifelong learning opportunities; and (4) complete support of the management team. 相似文献
