An application of a spatially distributed queuing model to an ambulance system

An application of a spatially distributed queuing model to an ambulance system is presented. The purpose of this research was to assess the usefulness of a variation of the “hypercube” queuing model developed specifically for modeling an ambulance system. The model was applied to the emergency medical system of Greenville County, South Carolina using historical data. Results indicate that the model provides reasonably accurate estimates of system performance measures when the input parameters can be accurately specified.     

Corporate diversification,institutional investors and internal control quality

This study investigates the relationship between corporate diversification, institutional investors and internal control quality. Using a sample of firms disclosing internal control information from 1999 to 2011, the results show that corporate diversification is positively associated with the likelihood of internal control weakness. Moreover, this relationship is stronger (weaker) when firms have higher transient (dedicated) institutional ownership, indicating that transient (dedicated) institutional investors increase (mitigates) the internal control problems arising from diversification. This study contributes to the literature by providing evidence on the role of corporate diversification in the quality of internal control.     

Civil regulation and HRM: the impact of civil society organisations on the policies and practices of employers

While the concept of civil regulation has begun to feature in the business and management literature, it has yet to be applied to the management of people at work. Data from a study of how civil society organisations try to influence directly the policies and practices of employers are used to examine how civil regulation operates in the field of HRM. An approach to conceptualising regulatory systems is used as a framework for demonstrating the main characteristics of civil regulation. The development of civil regulation attests to the complex regulatory environment governing HRM, highlighting the continued importance of institutions in an original and distinctive manner.     

Foreign investment and bribery: A firm-level analysis of corruption in Vietnam

Among the concerns faced by countries pondering the costs and benefits of greater economic openness to international capital flows is the worry that new and powerful external actors will exert a corrupting influence on the domestic economy. In this paper, we use a novel empirical strategy, drawn from research in experimental psychology, to test the linkage between foreign direct investment (FDI) and corruption. The prevailing literature has produced confused and contradictory results on this vital relationship due to errors in their measurement of corruption which are correlated with FDI inflows. When a less biased operationalization is employed, we find clear evidence of corruption during both registration and procurement procedures in Vietnam. The prevalence of corruption, however, is not associated with inflows of FDI. On the contrary, one measure of economic openness appears to be the most important driver of reductions in Vietnamese corruption: the wave of domestic legislation, which accompanied the country's bilateral trade liberalization agreement with the United States (US-BTA), significantly reduced bribery during business registration.     

Changes in Inequalities of Access to Dental Care in Australia 1977–2005

Information on dental visits, income and demographic variables were drawn from the Australian National Health Survey between 1977 and 2005. Income‐related inequality in access to dental care was calculated using the generalised concentration index (G) and decomposition methods were employed to examine associations with socio‐demographic and policy‐amenable factors. Statistically significant increases in inequality in dental care use were found after 1995. From 0.026 in 1995, G increased to 0.045 in 2005. The associations between increases in inequality and changes in the uptake of private health insurance suggest a contributory role of the introduction of the Commonwealth government's 30 per cent rebate for private health insurance.
