This paper argues that evaluations of public–private partnerships thus far point to contradictory results regarding their effectiveness and value-for-money. Despite continuing political popularity, greater care is needed to strengthen future evaluations and conduct such assessments away from the policy cheerleaders.  相似文献

We investigate optimal portfolio choice for an investor who is skeptical about the degree to which excess returns are predictable. Skepticism is modeled as an informative prior over the R2R2 of the predictive regression. We find that the evidence is sufficient to convince even an investor with a highly skeptical prior to vary his portfolio on the basis of the dividend-price ratio and the yield spread. The resulting weights are less volatile and deliver superior out-of-sample performance as compared to the weights implied by an entirely model-based or data-based view.  相似文献

The Syrian government and international development agencies commonly present water scarcity as being one of Syria's main development challenges. This paper draws on a set of international reports, written in consultation with Syrian officials, to reveal the politics of this scarcity. I show how water scarcity is constructed and ordered through spatial representations. Rather than accepting the common explanation that scarcity is the result of population pressure, I argue that Syria's water scarcity is a consequence of the ruling Ba?th party's continuous promotion of water-intensive agriculture. This support for the agricultural sector, motivated in part by a desire for food self-sufficiency and growth through an expansion in irrigated agriculture, is linked to the rural roots of the Ba?th party and the influential Peasants Union. In revealing these key national politics, this analysis highlights how geopolitical studies of water in the Middle East must move beyond a focus on inter-state dynamics and pay critical attention to the politics operating around water distribution and use on a range of scalar levels.  相似文献

Total product quality is multidimensional and includes customer acceptance as well as the usual quantitative elements for conformance, performance and reliability. Also included are broad ranges of operational expectations that are specific to the particular product. Thus to assess overall quality requires analysis of a multi-attribute vector of quality measures, some of which are subjective but cannot be ignored in making quality-related decisions. Warranty costs reflect the overall effect of these elements and can serve as an overall measure for making economic decisions. In this paper, we will summarize warranty cost models and describe two warranty planning problems that are important in engineering economic decision making.  相似文献

Flood risk insurance can be an effective tool in assisting the restoration of damaged property after a flood event and sustaining communities through difficult times. It can also form part of a wider flood risk management strategy. In the light of recent flood events in the UK and in the context of changing property insurance markets, the universal cover previously enjoyed by floodplain residents has been called into question. Conflicting media and industry views leave the floodplain resident and the wider community in confusion. A survey of floodplain residents in England regarding their experience with flooding and flood insurance in England has been undertaken. The results reveal that some floodplain residents do indeed encounter difficulties when seeking insurance for their homes. However, despite the risk‐averse policies of some insurers, availability of insurance is still strong in both at‐risk and previously flooded locations. Success in gaining insurance may lead to complacency among residents who see no advantage in pursuing other, more costly, damage mitigation actions. As a tool in risk management, therefore, the market is prevented from realising its potential by competition, which results in a lack of a consistent approach, rewards homeowners' search strategies and reduces information flow.  相似文献

The term collaboration has been used throughout a variety of research disciplines to describe multiple types of interaction; yet, a unified, comprehensive definition of the construct remains elusive. This lack of clarity regarding the distinctions and commonalities between collaboration and other interaction concepts has resulted in conceptual confusion that affects practice and research in human resource management. Practitioners see collaboration as more of a buzzword than as an effective human resource strategy. Previous theory development efforts have not yet taken a comprehensive multidisciplinary approach. This has resulted in failure to integrate key themes across disciplines into an overall view of collaboration, which is a commonplace practice in business and military sectors alike. This paper describes a multidisciplinary conceptualization of collaboration and discusses the implications of this integrative theory to human resource management and strategy development as well as future research efforts.  相似文献

An Empirical Study of Environmental Awareness and Practices in SMEs   总被引:1,自引:0,他引:1  
With increasing awareness of environmental issues, there has been rising demand for environmental-friendly business practices. Prior research has shown that the implementation of environmental management practices is influenced by existing and potential stakeholder groups in the form of external pressures from legislators, environmental groups, financial institutions and suppliers, as well as internally by employees and owner/manager attitudes and knowledge. However, it has been reported that despite business owner/managers having strong “green” attitudes, the level of implementation of environmental-friendly practices is low. In order to explore the connection between pressures for improved practices and the management actions taken, this article examines how influence from various stakeholders is related to awareness of environmental issues, and how this awareness relates to actions taken within the businesses to reduce the environmental impact of their operations. The results indicate that legislation does result in general environmental awareness, and that organizations are then willing to␣change their business processes and environmental strategies. However, despite their actions they have little awareness of the benefits that might arise from cost reductions from their environmental-friendly practices. Those influenced by their suppliers act to reduce waste, but do not put into place formal environmental management systems, or use environmental messages to market their goods or services. Nevertheless, it can be argued that they have a real commitment to environmental issues, as evidenced by a willingness to voluntarily contribute to environmental organizations.  相似文献

A primary cause of food waste in households is a lack of food capabilities. Yet, the antecedents of food capabilities and its relationship with causes of food waste across different situational contexts remain poorly understood. We apply self-efficacy theory in combination with convenience orientation and good provider identity in a mixed-methods study. Findings reveal that the sequential structure of self-efficacy explains how capabilities contribute to food waste avoidance. A good provider identity, however, increases food waste, and also turns out to further convenience orientation. Food capabilities, in turn, reduce convenience orientation. Qualitative insights shed light on consumer's own accounts of their abilities. The findings contribute to a theory-based understanding of how consumers manage the complex issue of food waste. Findings imply that public policy and marketing should aim to strengthen consumers' self-efficacy beliefs and redefine the good provider identity, in particular in social contexts, to reverse its effect on waste.  相似文献
