Evidence of a decline in public trust associated with food risk governance over recent years has called into question the appropriateness of the current dominant risk analysis framework. Within the EU-funded SAFE FOODS project a novel risk analysis framework has been developed that attempts to address potential shortcomings by increasing stakeholder (including consumer) input, improving transparency, and formally incorporating benefit and non-health aspects into the analysis. To assess the viability of this novel framework, the views of food risk experts from the EU and beyond were sought using a distributed online questionnaire process called Delphi. In this paper the main results of this survey are described, revealing varying levels of support for the key innovations of the novel framework. Implications of our results for the new and old frameworks, for the future of risk analysis, and for the policy community more widely, are discussed.  相似文献

Supply contract with options   总被引:1,自引:1,他引:1  
The purpose of this paper is to analyze the impact of an option contract for two companies of a supply chain: retailer and supplier. With an option contract the retailer orders a quantity of units and has the right to modify his order if necessary. A model to calculate the performance of an option contract in terms of contract value for the two companies engaged is presented. The two considered cases are multiple suppliers and one retailer, and one supplier and one retailer. The performance improvement obtained using this kind of contract is compared by simulation.  相似文献

This study explores the extent to which local amenities are related to house price volatility, returns and risk‐adjusted returns across 238 MSAs. We find strong evidence that high amenity areas experience greater price volatility. In regards to returns, high amenity areas experience greater (lower) real returns in appreciating (depreciating) markets. However, high amenity areas experience little to no abnormal risk‐adjusted returns. Results from the study are robust to an endogenous treatment of amenities and land supply elasticity. Overall, we conclude that the desirability of a metropolitan area is a significant channel through which land values drive house price dynamics.  相似文献

Replanning is often used to optimize results of an activity in an ever changing world. To address the challenge of preparing future engineers for success, a special course was created for all engineering freshmen of the Faculty of Engineering of the University of Porto, in Portugal. Presented as a case study, this special course underwent a careful replanning as a result of several years of experience in teaching practice alongside with a theoretical deepening in pedagogical and technological issues, under the aegis of the action-research methodology. Within the context of the case study course, the mentioned replanning was also based on a theoretical approach that clearly identifies teaching–learning-assessment methodologies that promote regulation from those that foster emancipation, using a specific instrument: a taxonomy of educational processes. The replanning was designed to globally boost results regarding the educational aims of the course such as furthering freshmen’s integration into work environment and preparing them for success by fostering transversal skills (needed for study and work). Technology is seen as a mean of education enrichment as well as a productivity tool. The introduced innovations include fun-but-educational activities, several types of assessment over time and specific technological tools which were critical for the educational impact/achievement of this course. Success is demonstrated by encouraging feedback from the stakeholders, high students’ classifications and a steady reduction in retention. It is advocated that large portions of the reasoning behind the replanning can be extrapolated to other courses.  相似文献

Team learning should be an important construct in organizational management research because team learning can enhance organizational learning and overall performance. However, there is limited understanding of how team learning works in different cultural contexts. Using an international comparative research approach, we developed a framework of antecedents and outcomes in the higher education context and tested it with samples from the UK and Vietnam. The results show that a common framework is applicable in the two different contexts, subject to slight modifications. However, this study does not find that team learning (measured via the proxy of “attitude towards team learning”) exhibits any statistically significant relationship as a predictor of the proposed outcomes. Other findings from this study on educational contexts are important not only to scholars in this field, but also for practicing managers, particularly those who study and operate in the extensive global market.  相似文献

The existence of free technologies is prevalent in a variety of industries from software to design. This study examines the competitive interaction between free and priced technologies. I draw on the literature on economic logics to predict that, in general, technologies that are freely shared are likely to stimulate interest and provide useful market information without directly competing with priced technologies. In contrast, due to direct competition, I predict that the prevalence of priced technologies will decrease the sales of other priced technologies. I find support for these hypotheses using a sample of more than 1 million transactions in over 200 distinct markets for MobileApps for the Palm computing platform. This study highlights how free technologies can be utilized to enhance performance of commercial producers. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Research summary : This research extends agglomeration theory by joining it with information economics research to better understand the determinants of firms' organizational governance choices. We argue that co‐location in a common geographic cluster fosters lower levels of information asymmetry between exchange partners and thus leads firms to employ acquisitions rather than alliances for their external corporate development activities. We further extend agglomeration theory by arguing that the impact of sharing a cluster location on acquisitions versus alliances strengthens with the level and dissimilarity of the exchange partners' knowledge‐based resources as well as with the intra‐cluster geographic proximity of the partners. Evidence from a sample of over 1,100 alliance and acquisition transactions in the U.S. semiconductor industry provides support for our hypotheses. Managerial summary : This paper investigates the role of geographical clustering for firms' external corporate development activities in acquisitions and alliances. We explain how better information is likely to be available among firms co‐located in the same cluster. This suggests that managers should have less need to use alliances over acquisitions as a means of reducing the risk of adverse selection (e.g., overpaying for acquisitions). Our investigation of over 1,100 transactions in the U.S. semiconductor industry shows that common cluster co‐location increases the probability of acquisition relative to alliance. Our arguments and evidence also indicate that the information‐related benefits of cluster co‐location are even more impactful when the parties have more divergent technology bases, possess larger stocks of knowledge‐based resources, or are located in closer geographic proximity.

The current study seeks to answer a number of key questions concerning the strategic management of frontline employees (e.g. individuals who do not occupy an executive, managerial or supervisory role in functions such as production, maintenance, service and clerical functions) and their contributions towards the performance of small- and medium-sized manufacturing firms in Australia. This study adopts a human capital perspective to examine the employee and organisational performance of small and medium enterprises (SMEs) in Australia. We were also interested in seeking to examine the presence of the human resource management (HRM) function of SMEs in Australia and their contribution towards employee and firm performance. Findings from the partial least square analysis identified the antecedents and consequences of a human capital enhancing (HCE) approach for the strategic HRM of frontline employees in Australia's manufacturing industry. Strategic orientations of small- and medium-sized manufacturing firms mediate the contribution of the HRM function in adopting a set of HCE HRM systems. HCE HRM system was found to have a direct and indirect impact on manufacturing performance outcomes. Frontline employees' performance was found to mediate the impact of HCE HRM system on manufacturing performance outcomes. Theoretical and practical implications are discussed in relation to the management of frontline employees in enhancing perceived employee and manufacturing performance.  相似文献

Investigation of the cultural factors that may influence the employment decisions of managers is of increasing importance in the global business environment. The purpose of this research is to examine whether particularistic ties based on friendship influence hiring practices in relation-based (Hong Kong Chinese) and rule-based (Australian) cultural contexts. Three studies were conducted to examine this research question. Results indicate that friendship-based particularistic ties, specifically guanxi and mateship, can influence hiring decisions in both relation- and rule-based cultural contexts. The results of the studies have implications for human resource managers with regards to staffing organizations operating in different cultural contexts.  相似文献
