考虑公平关切的供应链契约与协调

供应链契约是影响供应链整体绩效的重要因素.在传统两阶段供应链中引入公平关切,研究了公平关切行为倾向对供应链契约与协调的影响.文中假设零售商是公平关切的,在此假设下展开行为运筹分析,分别探讨了零售商的公平关切行为倾向对批发价契约,收益共享契约和回购契约等协调性的影响,并用算例加以验证.最后,在此基础上提出并证明了一般性结论:零售商的公平关切不会改变供应链的协调状态.     

Supplier integration and firm performance: the moderating effects of internal integration and trust

This study proposes and empirically tests a model of the moderating effects of internal integration and trust on the impacts of information, process and strategic integration with suppliers on firm performance using structural equation modelling and data collected from 261 manufacturing firms in Vietnam. The results show that all three types of supplier integration positively associate with firm performance. Internal integration enhances the impact of process integration with suppliers on firm performance, but does not moderate the impacts of information and strategic integration with suppliers. Internal trust has insignificant, positive and negative influences on the effects of information, process and strategic integration with suppliers on firm performance. The findings show that internal integration and trust play different roles in moderating the positive effects of information, process and strategic integration with suppliers on firm performance, which elucidates a possible reason for previous mixed findings on the relationship between supplier integration and firm performance.     

Caseworkers as a source of hope leading to perceptions of academic success for transitional age foster youth

Research among adolescent samples has consistently demonstrated that a hopeful mindset is associated with resilience and global well-being. Further, research suggests that hope is influenced from an early age from connections with supportive caregivers. However, because older youth in the child welfare system may lack supportive caregivers, alternative sources of hope may be needed. To test a theory that supportive child welfare caseworkers can serve as external sources of hope, we conducted a cross-sectional study of youth in the child welfare system from a single state (N = 149). Using surveys with established scales to measure the variables of interest, the study tested a structural equation model of (1) youth's external hope in their caseworker as a driver of (2) internal hope in themselves leading to (3) more positive perceptions of academic success. Perceptions of academic success were chosen as the final consequence of the model because academic success has been linked to many other variables of well-being across the lifespan. The results indicate that the proposed structural model fits the data well (χ² = 327.9, df = 150; P < 0.001; root-mean-square error of approximation [RMSEA] = 0.09 [90% confidence interval – CI: 0.076, 0.103]; comparative fit index [CFI]: 0.920; standardized root-mean-square residual [SRMR]: 0.05). The results indicate that youths' hope in themselves had origins in external hope in the caseworker. Moreover, the final consequence was an increase in perceptions of academic success. Such results have implications by revealing how case management services can positively influence foster youths' hope and thereby influence their academic success.     

Modeling the Effects of a Service Guarantee on Perceived Service Quality Using Alternating Conditional Expectations (ACE)*

This paper addresses the dearth of empirical research on the relationship between service guarantee and perceived service quality (PSQ). In particular, we examine the moderating effects of a service guarantee on PSQ. While a recent study provided empirical evidence that service quality is affected by service guarantee and employee variables such as employee motivation/vision and learning through service failure, the nature and form of the relationships between these variables remain unclear. Knowledge of these relationships can assist service managers to allocate resources more judiciously, avoid pitfalls, and establish more realistic expectations. Data was obtained from employees and customers of a multinational hotel chain that has implemented a service guarantee program in 89 of its hotels in America and Canada. As the employee variables could affect performance in a non‐linear fashion, we relaxed the assumption of model linearity by using the Alternating Conditional Expectations (ACE) algorithm to arrive at a better‐fitting, non‐linear regression model for PSQ. Our findings indicate the existence of significant non‐linear relationships between PSQ and its determinant variables. The ACE model also revealed that service guarantee interacts with the employee variables to affect PSQ in a non‐linear fashion. The non‐linear relationships present new insights into the management of service guarantees and PSQ. Explanations and managerial implications of our results are presented and discussed.
