This paper extends the literature on modelling healthcare cost data by applying the generalised beta of the second kind (GB2) distribution to English hospital inpatient cost data. A quasi‐experimental design, estimating models on a sub‐population of the data and evaluating performance on another sub‐population, is used to compare this distribution with its nested and limiting cases. While for these data the beta of the second kind (B2) distribution and generalised gamma (GG) distribution outperform the GB2, our results illustrate that the GB2 can be used as a device for choosing among competing parametric distributions for healthcare cost data.

Drowning is a major cause of injury and death worldwide. This study aims to expand the evidence in fatal and non-fatal drowning. A retrospective study was conducted to investigate fatal and non-fatal drowning incidents attended by ambulance paramedics in Victoria (Australia) from 2007 to 2012. A total of 509 drowning incidents were identified, 339 (66.6%) were non-fatal, with 170 (33.4%) resulting in death. Children aged 0–4 years had the highest crude drowning rate (7.95 per 100,000 persons). Non-fatal incidents were more likely to be witnessed by a bystander when compared with fatal incidents (43.7% vs. 20.0%, p < 0.001). Spatial analysis indicated that 35 (43.8%) local government areas (LGAs) were considered at ‘excess risk’ of a drowning event occurring. This study is the first to apply spatial analysis to determine relative risk ratios for fatal and non-fatal drowning. These findings will enable geographically targeted and age-specific drowning prevention activities. 相似文献

An analysis of policy and practice documents on information-sharing in the transition of military personnel into civilian life finds (1) a complex transition pathway along which the responsibility for co-ordination of transition shifts from service providers to those in transition; (2) a lack of attention to operationalizing information-sharing for different service circumstances; (3) the potential for developing a framework for managing information-sharing; and (4) a need for further research to draw on the evidence of transitions and information-sharing in other policy sectors. 相似文献

Evidence suggests that leisure coping is affiliated with resilience, and that both predict stress-coping and well-being. However, a theoretical explanation of how resilience is associated with the stress-reducing properties of leisure coping is lacking. Using the broaden-and-build theory, a model was developed proposing that resilient individuals proactively use leisure coping to cultivate positive emotions and in turn enhance well-being. Leisure coping and positive affect (PA) were suggested to mediate the relationship between resilience and well-being outcomes (stress and flourishing). The model was tested among 202 U.K undergraduates, a population reported to experience high stress. Structural equation modelling revealed that resilience had a significant positive effect on flourishing. Leisure coping beliefs demonstrated a positive relationship with resilience, PA and flourishing. PA mediated the relationship between resilience and flourishing and between resilience and stress. Leisure coping strategies did not meaningfully contribute to the model. Leisure beliefs may have emerged as more important than leisure strategies because leisure beliefs are relatively stable with more enduring effects on health and well-being, while leisure strategies are transient and situation-based. Future research should examine the relationships longitudinally to explore developmental change. Implications of the findings for undergraduates are discussed. 相似文献

This paper is concerned with whether women are less likely to express business start‐up intentions because of a less favorable attitude to risk. Previous research suggests that attitude to risk differs significantly between genders, but has not addressed the question of whether this contributes to lower levels of female interest in venture creation. This paper describes a conceptual basis for this question, and investigates it using a survey of business start‐up intention from across a sample of European universities. A large proportion of the difference in average levels of intention between genders appears to be associated with attitude to risk. 相似文献

We use the upper and lower bounds derived by Ferson and Lin (2010) to examine the impact of investor heterogeneity on the performance of U.K. investment trusts relative to alternative linear factor models. We find using the upper bounds that investor heterogeneity has an important impact for nearly all investment trusts. The upper bounds are large in economic terms and significantly different from zero. We find no evidence of any trusts where all investors agree on the sign of performance beyond what we expect by chance. Using the lower bound, we find that trusts with a larger disagreement about trust performance have a weaker relation between the trust premium and past Net Asset Value (NAV) performance. 相似文献

Most previous empirical studies on foreclosure price discounts are based on data from housing-markets during periods of relative stability (Baton Rouge, Louisiana; Arlington, Texas; and Las Vegas, Nevada in 1980s and 1990s). The few studies with sample periods containing the Liquidity Crisis of 2008 were all focused on the Las Vegas market and even fewer studies have examined the pricing implications of short sale transactions. This study examines the discounts associated with foreclosure and short sale status in the Fresno, California from 2006 to 2010, a time period containing significant housing price volatility. Generally, we find approximately 20 % and 13 % discounts for foreclosure transactions and short sale transactions, respectively. These discounts remain consistent even after controlling for endogeneity of time-on-the-market and self-selection bias. We also document that both the foreclosure and short-sale discounts are time varying based on market conditions. Both foreclosure and short-sale discounts increase from 2008 to 2009 and decrease in 2010. Also, the foreclosure status decreases time on the market while the short-sale status increases time on the market. 相似文献

The article examines the impact of executive ownership and other ownership and governance factors on employment change after takeovers. Drawing on a dataset of 235 takeovers, the results show that there is a reduction in employment in just over 50 per cent of the sample. Higher levels of executive share ownership are associated with lower probabilities of employee layoffs post‐takeover, and there is a positive relationship between executive ownership and employment growth. The effect of executive options on employment change is generally insignificant, as are the effects of other features of ownership and governance. The evidence suggests that executives with higher levels of ownership tend to mount takeovers of better‐performing firms and to implement takeovers aimed at growth. 相似文献

We examine cross‐national variation in the global growth of commercial microfinance from 1998 to 2009 as a natural experiment to analyze the role of national institutions in shaping the ability of commercial enterprises to reach the global poor. Our results demonstrate that a country's level of state fragility represents an important institutional context of poverty that explains significant cross‐national variation in the commercial microfinance industry's ability to grow its client base, control costs, and attract commercial capital. Moreover, we find that commercial microfinance lenders have experienced greater difficulty than nonprofit lenders in growing their client base in more fragile state settings. Our results support the proposition that the state shapes both institutional hazards and opportunities for business‐led efforts to combat global poverty. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
