The importance of informal professional networks in developing a proactive organizational culture: a public value perspective

Public value theory was used by the authors to investigate informal professional networks, perceived discretionary power, and the organizational culture that forms in physical asset management organizations. The results, from a structural equation model, indicated that informal professional networks are positively associated with higher discretionary power and a proactive asset maintenance organizational culture. In the absence of public managers promoting public value, professionals use their informal networks as a source of power to be proactive and contribute to asset reliability and public safety (public value).     

Identification and Estimation of Distributional Impacts of Interventions Using Changes in Inequality Measures

This paper presents estimators of distributional impacts of interventions when selection to the program is based on observable characteristics. Distributional impacts are calculated as differences in inequality measures of the marginal distributions of potential outcomes of receiving and not receiving the treatment. The estimation procedure involves a first non‐parametric estimation of the propensity score. In the second step weighted versions of inequality measures are computed using weights based on the estimated propensity score. Consistency, semi‐parametric efficiency and validity of inference based on the percentile bootstrap are shown for the estimators. Results from Monte Carlo exercises show its good performance in small samples. Copyright © 2015 John Wiley & Sons, Ltd.     

Effects of justice and utilitarianism on ethical decision making: a cross‐cultural examination of gender similarities and differences

This study investigates the relationship between intention to behave ethically and gender within the context of national culture. Using Reidenbach and Robin's measures of the ethical dimensions of justice and utilitarianism in a sample of business students from three different countries, we found that gender is significantly related to the respondents' intention to behave ethically. Women relied on both justice as well as utilitarianism when making moral decisions. By contrast, men relied only on justice, and did not rely on utilitarianism when faced with the same ethical issues. Further, women's intention to behave was contextual, significantly affected by two national culture dimensions (uncertainty avoidance and individualism), whereas men's decisions were more universal, and not related to national culture dimensions.     

The heteroskedasticity-consistent covariance estimator in accounting

The main purpose of this paper is to compare the White (1980) heteroskedasticity-consistent (HC) covariance matrix estimator with alternative estimators. Many regression packages compute the White (1980) heteroskedasticity-consistent (HC) covariance matrix estimator. The common procedure in Accounting and Finance research to deal with the heteroskedasticity problem is based on this estimator, despite its worse finite-samples properties when compared with other consistent estimators. In this paper we compare several HC covariance matrix estimators based on a sample of 3706 European listed companies from Austria, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Portugal, Spain, Sweden and the United Kingdom. We conclude that HC standard errors increase when finite-samples more appropriate estimators are considered and in the most part of countries the Ohlson (1995) model coefficients estimates became statistically insignificant. This can be explained by the high leverage points in the design matrix. To the best of our knowledge it is the first time that these alternative estimators are compared with the one of White (1980) in accounting research.     

Currency crises in Brazil: the role of the fundamentals and the rumours

The paper aims at identification of the main explanatory factors of the currency crises in Brazil. Following Choueiri and Kaminsky (1997) a VAR monetary model is used and the historical decomposition procedure developed by Sims (1980) to evaluate the importance of the ‘fundamentals’ represented by fiscal/monetary and exchange-rate policies, and the ‘external factors’ represented by foreign interest rates and contagious effects. The main results show the importance of the exchange-rate management on the overall period and the contagious effects more recently to explain the Brazilian currency crises.     

A social network analysis of leading semiconductor companies’ knowledge flow network

This study (1) constructs a knowledge flow network for leading semiconductor companies; (2) seeks out how leading semiconductor companies can attain knowledge competencies (through patent activities or network position) via social network analysis; and (3) proposes critical strategic suggestions regarding knowledge flow networks in the industry. The results show (1) that a knowledge flow network with no isolators and Asian semiconductor firms are closely connected with other firms all over the world; (2) that patent activities are positively associated with central network positions and firm performance; (3) that closeness centrality is helpful for patent citation activities and also helps to achieve better performance; and (4) that semiconductor companies in Asia are also closely connected with others in the world.     

Implications for research

We aimed to study the anatomical distribution, severity, and outcome of hospitalised trauma pedestrian patients in Al Ain, United Arab Emirates (UAE), so as to improve preventive measures. All pedestrian trauma patients who were involved with a road traffic collision and admitted to Al Ain Hospital for more than 24 hours or who died in the hospital were included in the study. Data were prospectively collected during March 2003–October 2007. Three hundred and eighteen patients were studied, 279 (87.7%) were males. Median (range) age was 31 (1–75) years. UAE nationals were significantly younger than non-nationals (median (range) age of 14 (2–75) years compared with 33 (1–75) years, p = 0.001, Mann–Whitney U-test). The lower limb (57.2%) was the most common injured region followed by the head (46.9%). The median (range) Injury Severity Score of patients was 5 (1–45). The median (range) total hospital stay was 11.3 (1–130) days. Thirty patients died (overall mortality 9.4%). In conclusion, mortality of pedestrian injured patients in the UAE is high. Severe head injury was the main cause of death. Measures to improve pedestrian safety should be adopted so as to reduce morbidity and mortality. These include educating drivers and pedestrians on road safety and enforcement of traffic safety laws.     

The impact of supervisor–subordinate relationships on morale: implications for public and private sector nurses' commitment

This paper used leader–member exchange theory as a lens for comparing the impact of the supervisor–subordinate relationship on public and private nurses' perceptions of morale and affective commitment. Many countries that are part of the Organisation for Economic Co-operation and Development are experiencing nurse shortages, and this theoretical framework proved insightful into factors contributing to turnover. The findings suggested that private sector nurses are significantly more satisfied with their supervision, enjoy greater morale and are more committed to their organisations. However, both groups were only slightly satisfied with their supervisor–subordinate relationships, implying that present management practices are not ideal for promoting effective workplace relationships. Implications for health-care management are discussed.
