This article presents findings from a study of control operators that raise concerns about safety-critical knowledge, culture and training. It is argued that the adoption of automated control systems can hinder the transfer of knowledge amongst operators, and this becomes an increasingly serious hazard as tacit knowledge is lost because of employee turnover. 相似文献

This paper develops a mathematical programming model for obtaining a best set of sites for planned facilities. The model is concerned with those situations where resource constraints are present. The specific setting for the paper involves the selection of sites for a set of retail outlets, wherein the ratio of aggregate outputs to inputs for the selected set is maximal among all possible sets that could be chosen. At the same time, the model guarantees that the only sets of stores allowable are those for which the available resources are used to the maximum extent possible. 相似文献

AbstractThis paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement. 相似文献

Sustainability of increasing relevance also for seafood markets. The aim of this contribution is to analyze consumer preferences and their willingness to pay (WTP) for different sustainability claims, and to identify consumer segments according to their WTP. The contingent valuation method was applied to elicit consumers’ WTP in eight European countries. The WTP varies between seven and almost 20%, depending on attribute and country. Three consumer groups become apparent: the largest group without any additional WTP, a smaller group with a moderate additional WTP of plus 17%, and a very small group with an additional WTP of more than 40%. Clear differences between countries are obvious regarding preferences for different sustainability attributes, particularly in the segment with the highest WTP. A fraction of the consumers is willing to pay significantly higher prices for sustainably produced fish from Europe: given that trustful standards are applied and well communicated. 相似文献

The purpose of this article is to analyse one of the very first European-level instances of trade union and social movement interaction in defence of the public sector, namely, the Coalition for Green and Social Procurement, an alliance of European trade unions and green and social non-governmental organisations (NGOs), and its campaign for an amendment of the new public procurement directives from 2000 to 2003. It will be examined to what extent this campaign was able to change the directives and counter neoliberal restructuring effectively as well as what the possibilities but also limits of trade union and social movement cooperation are as exemplified in this particular case study. 相似文献

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant-sensing system to determine winter wheat nitrogen requirements. We find that plant-sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system. 相似文献

In this paper the impact of price risk on millet production in Niger is investigated. The hypothesis that farmers respond to output price risk is tested. The results indicate that millet acreage planted decreased when millet price risk increased or when price risk of the competing crop decreased and therefore farmers do respond to changes in risk. 相似文献

The purpose of this research reflection is to set the stage for a more detailed research agenda in exploring event sport tourism experiences of support partners (SPs) during events. Using photo elicitation, the article presents a preliminary empirical case study. Visual materials were assembled by three female participants to interrogate how SPs experience “spectator space” and explore the processes that produced those experiences, an area of study that remains relatively unexplored in leisure research. Initial findings show how waiting to see the triathlete can be anxiety-provoking, but the release of emotion when smiles are exchanged constitutes core activities of being there. However, there are more questions than answers, and there is a need for further inquiry. Suggestions for future research on the impact of serious leisure on intimate others are given. 相似文献
