AbstractPublic concern is a pivotal notion in the risk perception, communication and management literature. It is, for example, a central concept with regard to the social amplification of risk, and as a justification for policy attention. Despite its ubiquity, the notion of public concern remains a ‘black box’ presenting a poorly understood state of affairs as a reified matter-of-fact. Paying attention to the deployment and metrics of public concern, and the work it is required to do, will enhance the power of approaches to understanding risk, and policymaking. Thus, the broad purpose of this paper is to unpack the notion of public concern by adopting an ontological yet critical perspective, drawing on a range of literature that considers ontology. We reflect on how publics and public concern have been conceptualised with regard to the dichotomies of individual/social and private/public, given that they imply different levels and dimensions of concern. We draw on empirical work that illuminates the assessment and measurement of public concern and how the public have responded to risk events. Considering public concern through an ontological lens affords a means of drawing renewed critical attention to objects that might otherwise appear finished or ready-made. 相似文献

Background Lung cancer is the most common type of cancer in the world and is associated with significant mortality. Nivolumab demonstrated statistically significant improvements in progression-free survival (PFS) and overall survival (OS) for patients with advanced squamous non-small cell lung cancer (NSCLC) who were previously treated. The cost-effectiveness of nivolumab has not been assessed in Canada. A contentious component of projecting long-term cost and outcomes in cancer relates to the modeling approach adopted, with the two most common approaches being partitioned survival (PS) and Markov models. The objectives of this analysis were to estimate the cost-utility of nivolumab and to compare the results using these alternative modeling approaches.Methods Both PS and Markov models were developed using docetaxel and erlotinib as comparators. A three-health state model was used consisting of progression-free, progressed disease, and death. Disease progression and time to progression were estimated by identifying best-fitting survival curves from the clinical trial data for PFS and OS. Expected costs and health outcomes were calculated by combining health-state occupancy with medical resource use and quality-of-life assigned to each of the three health states. The health outcomes included in the model were survival and quality-adjusted-life-years (QALYs).Results Nivolumab was found to have the highest expected per-patient cost, but also improved per-patient life years (LYs) and QALYs. Nivolumab cost an additional $151,560 and $140,601 per QALY gained compared to docetaxel and erlotinib, respectively, using a PS model approach. The cost-utility estimates using a Markov model were very similar ($152,229 and $141,838, respectively, per QALY gained).Conclusions Nivolumab was found to involve a trade-off between improved patient survival and QALYs, and increased cost. It was found that the use of a PS or Markov model produced very similar estimates of expected cost, outcomes, and incremental cost-utility. 相似文献

Porter and Kramer (Harv Bus Rev 84(12):78–92, 2006; Harv Bus Rev 89(1/2), 62–77, 2011) introduced ‘shared value’ as a ‘new conception of capitalism,’ claiming it is a powerful driver of economic growth and reconciliation between business and society. The idea has generated strong interest in business and academia; however, its theoretical precepts have not been rigorously assessed. In this paper, we provide a systematic and thorough analysis of shared value, focusing on its ontological and epistemological properties. Our review highlights that ‘shared value’ has spread into the language of multiple disciplines, but that its current conceptualization is vague, and it presents important discrepancies in the way it is defined and operationalized, such that it is more of a buzzword than a substantive concept. It also overlaps with many other (related) concepts and lacks empirical grounding. We offer recommendations for defining and measuring the concept, take a step toward disentangling it from related concepts, and identify relevant theories and research methods that would facilitate extending the knowledge frontier on shared value. 相似文献

Assuring the quality of food products, especially their safety and nutrition levels, is an increasing focus for governments, companies, and international trade bodies. In choosing quality assurance programs, public and private decision-makers must assess the benefits and costs of expected improvements in food safety and nutrition. This article discusses methods for measuring these benefits and costs as well as how these valuations are related to the mix of voluntary and mandatory quality management systems used in particular countries or trading blocs. These relationships are illustrated by a short case study of safety assurance systems for meat and poultry products. 相似文献

We review current state-of-the-art practices for combining preference data from multiple sources and discuss future research possibilities. A central theme is that any one data source (e.g., a scanner panel source) is often insufficient to support tests of complex theories of choice and decision making. Hence, analysts may need to embrace a wider variety of data types and measurement tools than traditionally have been considered in applied decision making and choice research. We discuss the viability of preference-stationarity assumptions usually made when pooling data, as well as random-utility theory-based approaches for combining data sources. We also discuss types of models and data sources likely to be required to make inferences about and estimate models that describe choice dynamics. The latter discussion is speculative insofar as the body of literature on this topic is small. 相似文献

Food safety regulation: an overview of contemporary issues 总被引:4,自引:0,他引:4
This article discusses a number of issues that are influencing the evolution of food safety regulation in developed and, to a lesser extent, developing countries. Whilst not definitive, it aims to highlight those factors which are considered crucial to an understanding of contemporary food safety controls in both the public and private spheres. These issues include criteria applied to assess the need/justification for food safety regulation, relationships between public and private food safety control systems, alternative forms that public food safety regulation can take, strategic responses to food safety regulation, and the trade implications of national food safety controls. The article serves as an introduction to these issues, which are discussed at greater length in the other papers that make up this special issue of Food Policy. 相似文献

Using a two‐period model this paper examines the quantity decisions of leveraged duopolists that are vulnerable to bankruptcy in the first period. When the firms have symmetric costs, a bankrupt firm reorganizes under Chapter 11. If a Chapter 11 firm experiences marginal cost relief, each firm produces a collusive output in period one in order to prevent its rival's financial demise. When the firms have asymmetric costs, the less efficient firm is liquidated under Chapter 7 upon bankruptcy. A predatory equilibrium exists, whereby the inefficient firm is driven from the market.

The macro-level business ethics in Scholasticism contrasts with modern Anglo-Saxon Capitalism, which is very influential worldwide. Scholasticism, developed between the thirteenth and the mid-seventeenth centuries, deals with key elements of free market morality, including private property, contracts, profits, prices, and free competition. For over 500 years Scholasticism tried to understand economic phenomena and business activities and reflected on them from an ethical perspective. Scholasticism offered the crucial lesson of the centrality of justice and the role of practical wisdom in considering market morality. Justice is seen as both a virtue and a principle, and commutative justice (justice in exchanges) with the common good of society as the reference for the Scholastics, is regarded as being especially important. 相似文献

Concentration and decentralization: The new geography of freight distribution in US metropolitan areas 总被引:1,自引:0,他引:1
Julie Cidell 《Journal of Transport Geography》2010,18(3):363-371
This paper examines the suburbanization of warehousing and trucking activity within US metropolitan areas between the 1980s and the present using Gini indices as a measure of concentration. While historical work exists on the relocation of transportation and warehousing activity to suburban locations, there has been little to document the most recent shifts in warehousing and logistics. This research does so via spatial analysis of Economic Census data, finding that while most US metropolitan areas have experienced decentralization in the spatial distribution of freight-related activity, there is also some growth in core counties, indicating that a more complex process is going on than simple suburbanization. 相似文献
