Understanding and managing supply chain risks is a critical functional competency for today's global enterprises. A lack of this competency can have significant negative outcomes, including costly production and delivery delays, loss of future sales, and a tarnished corporate image. The ability to identify and mitigate risks, however, is complicated as supply chains are becoming increasingly global, complex, and interconnected. Drawing on the complex systems and epidemiology literature, and using a computational modeling and network analysis approach, we examine the impact of global supply network structure on risk diffusion and supply network health and demonstrate the importance of supply network visibility. Our results show a significant association between network structure and both risk diffusion and supply network health. In particular, our results indicate that small‐world supply network topologies consistently outperform supply networks with scale‐free characteristics. Theoretically, our study contributes to our understanding of risk management and supply networks as complex networked systems using a computational approach. Managerially, our study illustrates how decision makers can benefit from a network analytic approach to develop a more holistic understanding of system‐wide risk diffusion and to guide network governance policies for more favorable health level outcomes. The article concludes by highlighting the main findings and discussing possibilities of future research directions. 相似文献

This paper suggest an organizing framework for developing social indicator research of the military and its relationship to larger society. Military activities are divided into seven categories which parallel civilian institutional sectors: (1) economy and labor force, (2) education, (3) crime and deviance, (4) science and technology, (5) health and health care, (6) population and family, and (7) politics and government. In each activity area each of the following three topics is discussed: (1) impacts of civilian social changes on the military, (2) patterns of internal military change, (3) impacts of changes in the military on civilian society. For each topic in each category we briefly review some relevant issues, classifying references by the topics and categories to which they relate. 相似文献

The goals of this study were to examine the additive and interactive effects of cumulative risk and child negative emotionality on children's social competence in the transition from preschool to school and to test whether these associations were mediated by child emotion regulation within a sample of 310 low‐income, ethnically diverse boys. Multiple informants and methods were used to measure contextual risk factors and negative emotionality at the ages of 1.5 and two, emotion dysregulation at the age of 3.5, and social competence in the home at the age of five and in school at the age of six. Results indicated that the relation between cumulative risk and emotion dysregulation was amplified for children with higher levels of negative emotionality. In turn, emotion dysregulation predicted lower social competence across both the home and the school contexts. This study represents an early effort to develop an integrative model of social competence by considering joint contributions of contextual risk, negative emotionality, and emotion regulation. 相似文献

The effect of parental depression on children's adjustment has been well documented, with exposure during early childhood particularly detrimental. Most studies that examine links between parental depression and child behavior are confounded methodologically because they focus on parents raising children who are genetically related to them. Another limitation of most prior research is a tendency to focus only on the effects of maternal depression while ignoring the influence of fathers’ depression. The purpose of this study was to examine whether infants’ exposure to both parents’ depressive symptoms, and inherited risk from birth mother internalizing symptoms, was related to school age children's externalizing and internalizing problems. Study data come from a longitudinal adoption study of 561 adoptive parents, biological mothers, and adopted children. Adoptive fathers’ depressive symptoms during infancy contributed independent variance to the prediction of children's internalizing symptoms and also moderated associations between adoptive mothers’ depressive symptoms and child externalizing symptoms. 相似文献

We introduce new estimators of the inhomogeneous K-function and the pair correlation function of a spatial point process as well as the cross K-function and the cross pair correlation function of a bivariate spatial point process under the assumption of second-order intensity-reweighted stationarity. These estimators rely on a ‘global’ normalisation factor which depends on an aggregation of the intensity function, while the existing estimators depend ‘locally’ on the intensity function at the individual observed points. The advantages of our new global estimators over the existing local estimators are demonstrated by theoretical considerations and a simulation study. 相似文献

This paper reports on and discusses the results of part of the author's PhD study. It focuses on professionals' perceptions of the factors that contribute to young people in residential children's homes coming to the attention of the criminal justice system, with consideration given to how such perceptions might impact on responses to the young people. As part of a case study of a particular local authority area, the author undertook semi‐structured interviews and a focus group with 31 professionals from the care and criminal justice systems. The implications of the findings for policy and practice are discussed. 相似文献
