Public–Private Partnerships (PPPs) have become a critical vehicle for delivering infrastructure worldwide. Yet, the use of such a procurement strategy has received considerable criticism, as they have been prone to experiencing time/cost overruns and during their operation poorly managed. A key issue contributing to the poor performance of PPPs is the paucity of an effective and comprehensive performance measurement system. There has been a tendency for the performance of PPPs to be measured based on their ex-post criteria of time, cost and quality. Such criteria do not accommodate the complexities and lifecycle of an asset. In addressing this problem, the methodology of sequential triangulation is used to develop and examine the effectiveness of a ‘Process Management Life Cycle Performance Measurement System’. The research provides public authorities and private-sector entities embarking on PPPs with a robust mechanism to effectively measure, control and manage their projects’ life cycle performances, ensuring the assets are ‘future proofed’.  相似文献

Numerous studies and practical experiences with risk have demonstrated the importance of risk perceptions for people's behavior. In this narrative review, we describe and reflect upon some of the lines of research that we feel have been important in helping us understand the factors and processes that shape people's risk perceptions. In our review, we propose that much of the research on risk perceptions to date can be grouped according to three dominant perspectives and, thus, approaches to study design; they are: the characteristics of hazards, the characteristics of risk perceivers, and the application of heuristics to inform risk judgments. In making these distinctions, we also highlight what we see as outstanding challenges for researchers and practitioners. We also highlight a few new research questions that we feel warrant attention.  相似文献

ABSTRACT

Alcohol and substance use can challenge military veterans who live in rural communities. In 2016, the screening, brief intervention, and referral to treatment in Alabama (AL-SBIRT) program was implemented in west Alabama. The primary aim of this study was to determine whether current tobacco use modified the relationship between veteran status and substance misuse. Self-reported wellness data was collected regarding substance, alcohol, or tobacco consumption. Risk levels for alcohol and drug use were measured using the United States Alcohol Use Disorders Identification Test (US-AUDIT) and the Drug Abuse Screening Test (DAST)-10. Substance and tobacco use were significantly and positively correlated. Veterans had a higher US-AUDIT and DAST score than nonveterans, and tobacco appeared to be an exacerbating factor. Effective evidence-based interventions are needed in rural settings. Technology based programs and motivational interviewing with trained clinicians may serve as beneficial and cost-effective interventions for tobacco use prevention and cessation efforts.  相似文献

Abstract

This article discusses how the history of sports can serve as way to understand abstract concepts associated with local history and social studies education. An introductory discussion outlines how sports can engage and interest students, focusing especially on ideas related to history thinking (such as change and continuity). A case study using the Brooklyn Dodgers’ move to Los Angeles is used to illustrate these ideas, focusing on themes associated with suburbanization and urban renewal. A lesson plan is also provided.  相似文献

Abstract

Nudge theory describes how indirect suggestions and positive reinforcement can influence decision-making. We used nudge theory to implement a traffic-light labeling and choice architecture (modifying product placement) intervention at Harvard University cafeterias, but found no significant change in sales. Survey and focus group data showed that some students thought the labeling may exacerbate eating disorders, however, there is extremely limited research on potential negative consequences of labeling. One way to describe these findings is through 20th century philosopher Michel Foucault’s concept of biopower. Biopower manipulates cultural norms and nudges individuals to engage in self-surveillance and self-discipline, de facto subjugating themselves to certain ways of being. Biopower may lead to the creation of an in-group and an out-group based on who can adopt the new behaviors, such as healthy eating. Those in the out-group may face additional unintended consequences, highlighting the need for mixed-methods research to better evaluate public health interventions.  相似文献

ABSTRACT

The Paralympic games is a pedagogic, pervasive, political, powerful, and ‘popular’ cultural site where the heightened visibility of disability bring into being specific forms of disability as they articulate within cultures, institutions and practices. Regarded as a ‘positive charge’ by Stuart Hall, the Paralympics intends to challenge the devalued disabled body politic of typical disability representation. This has been stimulated by the entry of Channel 4 as the UK Paralympic rights holders in 2012 which has seen greater media coverage of certain technologically enhanced cyborgian parasport bodies and an emerging celebrity / sexualized disability culture. This contemporary moment in disability representation provides a compelling space in which to (re-)address the gendered nature of hyper-visible Parasport hybrids, their potential to disrupt ‘normative’ relations of power, and, the wider impact on disability politics in a neoliberalised culture of widening and affective circuits of bodily inclusion and control. Drawing on an integrated content and textual analysis of 90?h of Paralympic programming from the Rio 2016 Games we highlight two emblematic segments so as to enhance our appreciation of contemporary disabled politics as it intersects with gender, technology and nation. We analyse these emblematic segments at the intersection of critical disability studies, cultural studies and sport, using concept of ablenationalism to highlight the extent certain technological capacitated parasport bodies perform gendered representational work as part of the seductive apparatus of neoliberal micro-governance suggestive of an emerging ecology of disability-gender relations. In doing so, we highlight the Paralympic contradictions and interrogate the assumed ‘positive charge’ of the contemporary (re-)presentation of disability.  相似文献

Maintaining the performance of infrastructure-dependent systems in the face of surprises and unknowable risks is a grand challenge. Addressing this issue requires a better understanding of enabling conditions or principles that promote system resilience in a universal way. In this study, a set of such principles is interpreted as a group of interrelated conditions or organizational qualities that, taken together, engender system resilience. The field of resilience engineering identifies basic system or organizational qualities (e.g., abilities for learning) that are associated with enhanced general resilience and has packaged them into a set of principles that should be fostered. However, supporting conditions that give rise to such first-order system qualities remain elusive in the field. An integrative understanding of how such conditions co-occur and fit together to bring about resilience, therefore, has been less clear. This article contributes to addressing this gap by identifying a potentially more comprehensive set of principles for building general resilience in infrastructure-dependent systems. In approaching this aim, we organize scattered notions from across the literature. To reflect the partly self-organizing nature of infrastructure-dependent systems, we compare and synthesize two lines of research on resilience: resilience engineering and social-ecological system resilience. Although some of the principles discussed within the two fields overlap, there are some nuanced differences. By comparing and synthesizing the knowledge developed in them, we recommend an updated set of resilience-enhancing principles for infrastructure-dependent systems. In addition to proposing an expanded list of principles, we illustrate how these principles can co-occur and their interdependencies.  相似文献
