Abstract

Here we describe the implementation of an experimental research tool called the Decision Game that we used to collect data on household flood risk management decisions. Participants using this tool play an interactive game that involves making household decisions about place of residence and a variety of household expenditures, including spending on flood insurance and private flood risk mitigation. Participants also answer survey questions before and after playing the game; the pre-game survey collected demographic information, and the post-game survey collected information about participant experiences with flooding and flood mitigation. Online and face-to-face participants showed similar engagement with the experiment, and most participants appeared to have made deliberate and considered decisions about risk mitigation. Online study participants had similar responses to those who participated in person, although face-to-face participants seemed slightly more likely to mitigate against risk. Overall, participants in this research were younger, more educated and more likely to rent a home than the average Canadian. Serious games may be useful for augmenting existing data gathering strategies used in understanding environmental decision making, particularly for rare catastrophic events for which stated preference surveys may be less informative. Serious games allow for sharing a mixture of information with study participants, including maps, video clips, text and even immersive 3D experiences, and can be administered online to increase participation levels. Future research will consider longer duration online experiments and more immersive interaction frameworks.  相似文献

The current study examines the relationship between adult attachment style and both perceived psychological contract breach and affective organizational commitment in a sample of college students with employment experience. Attachment style is argued to be an individual difference factor that affects how an individual perceives organizational events based on theory and existing empirical research related to adult attachment style. Individuals with insecure attachment styles were predicted to perceive more psychological contract breach and have lower levels of affective organizational commitment. The results reveal that individuals with higher levels of preoccupied and dismissive attachment styles perceived higher levels of psychological contract breach, and preoccupied attachment style significantly and negatively relates to affective organizational commitment. The relationship between attachment style and psychological contract dimensions was stronger for relational than transactional contract dimensions. Evidence is also found that perceived psychological contract breach mediates the relationship between preoccupied attachment style and affective commitment. Future potential research directions are described. The implications of these findings for managerial practice is discussed.  相似文献

This research extends overlapping streams of research examining asymmetric information, adverse selection, and buyer trust by presenting an empirical investigation of the process by which a market for “lemons” emerges in the claiming market for thoroughbred racehorses. The study focuses attention on the potential of quality signals and buyer trust to lessen the impact of adverse selection. Incorporating concepts from economics, marketing, and psychology, a conceptual model suggests that adversely selected racehorses, distinguished by an unintentional signal from sellers to potential buyers, will be priced lower than otherwise similar racehorses perceived to be less subject to adverse selection. Data from one day of claiming races at 16 American racetracks (744 racehorses) are used to test this study hypothesis. Results provide evidence for adverse selection and a mitigating quality signal in the thoroughbred claiming market. Implications for buyers and sellers in this market, as well as more general implications, are discussed and an avenue for future research is proposed.  相似文献

This paper reviews the evidence on the relationship between work and health. It concludes that, overall, the beneficial effects of work outweigh the risks of work, and are greater than the harmful effects of long-term worklessness. That contrasts with increasing trends of sickness absence, long-term incapacity and ill-health retirement attributed to common health problems. It suggests that there needs to be a fundamental shift in how we think about common health problems and work--in health care, the workplace and society.  相似文献

Protected areas in fishery management have been suggested to hedge management failures and variation in harvests. In this paper, a stochastic bioeconomic model of a two-species fishery in the Manning Bioregion is used to test the performance of protected areas as a management tool in a fishery. The establishment of a protected area is analysed under the assumption of heterogenous environments that are linked via density-dependent or sink-source stock dispersal relationships. The sensitivity of the results to different degrees of management is also explored. The model is applied to the Ocean Prawn Trawl, and Ocean Trap and Line fisheries within Manning Bioregion in New South Wales, Australia. The focus of the study is placed on the biological and institutional characteristics that yield benefits to the fishery. It was found that protected area use in the Manning Bioregion is likely to have differing effects on the two fisheries examined, benefiting Ocean Trap and Line fishers but adversely affecting Ocean Prawn Trawl fishers. Overall, it is unlikely that protected area use will lead to an increase resource rent in the fishery.  相似文献

Aims: To assess incremental charges of patients experiencing venous thromboembolisms (VTE) across various types of elective inpatient surgical procedures with administration of general anesthesia in the US.

Methods: The authors performed a retrospective study utilizing data from a nationwide hospital operational records database from July 2014 through June 2015 to compare a group of inpatients experiencing a VTE event post-operatively to a propensity score matched group of inpatients who did not experience a VTE. Patients included in the analysis had a hospital admission for an elective inpatient surgical procedure with the use of general anesthesia. Procedures of the heart, brain, lungs, and obstetrical procedures were excluded, as these procedures often require a scheduled ICU stay post-operatively. Outcomes examined included VTE events during hospitalization, length of stay, unscheduled ICU transfers, number of days spent in the ICU if transferred, 3- and 30-day re-admissions, and total hospital charges incurred.

Results: The study included 17,727 patients undergoing elective inpatient surgical procedures. Of these, 36 patients who experienced a VTE event were matched to 108 patients who did not. VTE events occurred in 0.2% of the study population, with most events occurring for patients undergoing total knee replacement. VTE patients had a mean total hospital charge of $60,814 vs $48,325 for non-VTE patients, resulting in a mean incremental charge of $11,979 (p?<?.05). Compared to non-VTE patients, VTE patients had longer length of stay (5.9 days vs 3.7 days, p?<?.001), experienced a higher rate of 3-day re-admissions (3 vs 0 patients) and 30-day re-admissions (7 vs 2 patients).

Conclusions: Patients undergoing elective inpatient surgical procedures with general anesthesia who had a VTE event during their primary hospitalization had a significantly longer length of stay and significantly higher total hospital charges than comparable patients without a VTE event.  相似文献

This paper critically examines the ‘asset transfer’ of leisure services from the public to the voluntary sector. Asset transfer might be theorised as ‘austerity localism’, in which volunteers are obliged to fill the gaps left by retreating public provision, or as ‘progressive localism’, which represents new opportunities through the localism and Big Society agendas to develop more locally responsive, cooperative and mutualist visions. In this way, asset transfer might overcome the limitations of the United Kingdom policies in which ‘Big Government’ is replaced by civic society. Drawing on qualitative interviews with key personnel (volunteers, managers and local authority officers) at 12 leisure facilities, a grounded assessment of the nuanced balance between ‘austerity localism’ and ‘progressive localism’ is provided, including three observations. First, the main impetus for transfer was cuts in local authority budgets which stimulated the emergence of local groups of volunteers. Secondly, the transfers themselves required interaction between local government and the volunteer groups; however, the nature of the relationship and support given varied and support was limited by austerity measures. Thirdly, volunteers do not automatically fill a gap left by the state: without support transfer viability relies on the financial and social capital among volunteer groups, and this is unevenly distributed. These findings suggest that the capacity for a ‘progressive localism’ to emerge through asset transfer is limited. However, where transfer has occurred, there are some progressive benefits of volunteer empowerment and a more flexible service.  相似文献
