Popular teamwork assessments have been strongly criticized on the grounds of poor psychometric properties and their disconnect with conceptual models of teamwork. These issues raise concerns with respect to our ability to evaluate efforts devoted to advancing teamwork in academia. We report the development of a teamwork assessment that builds on empirically supported conceptualizations of team processes. Two studies were conducted to test and to cross-validate the psychometrics of the resulting measure. In the discussion section, we address the implications of our findings for conceptual models of teamwork and provide guidelines for using the measure in business education. 相似文献

We approximate probabilistic forecasts for interval-valued time series by offering alternative approaches. After fitting a possibly non-Gaussian bivariate vector autoregression (VAR) model to the center/log-range system, we transform prediction regions (analytical and bootstrap) for this system into regions for center/range and upper/lower bounds systems. Monte Carlo simulations show that bootstrap methods are preferred according to several new metrics. For daily S&P 500 low/high returns, we build joint conditional prediction regions of the return level and volatility. We illustrate the usefulness of obtaining bootstrap forecasts regions for low/high returns by developing a trading strategy and showing its profitability when compared to using point forecasts. 相似文献

Business is expected to contribute to grand challenges (GC) such as poverty within their corporate social responsibilities. Multi-stakeholder initiatives (MSIs) have developed to a popular governance model to address GC. While existing scholarship has discussed the positive and negative aspects of MSIs, we know relatively little about how corporations within MSIs are held accountable. The objective of the study is to analyze the dynamics of accountability relationships between the corporate actor and the accountability forum to conceive a process model for effective accountability relationships in developing countries. We conducted an inductive study which explored the tensions the accountability forum perceives in MSI accountability relationships and the criteria to meet the forum's accountability claims. Our study identified four accountability criteria: transparency, inclusion, procedural fairness, and efficacy. Our main theoretical claim is that considering the four accountability criteria in the process of facilitating, dialoguing, and evaluating allows affected stakeholders to validate and match legitimacy claims with their own expectations, and thus, manage MSIs more effectively. Our contribution to existing scholarship on MSIs in developing countries is that we offer a novel perspective on analyzing the effectiveness of MSIs to address GC through our focus on one element of MSIs––specifically accountability. Beyond academic theorizing, this perspective may well hold value for nongovernmental organizations, policymakers, and business managers as it advances a concept of responsibility based on a set of accountability criteria which have the potential to become a cornerstone for how MSI members can organize to effectively address GC in developing countries. 相似文献

ABSTRACTIn light of the changing roles of customers from service co-producer to value co-creator, the customer participation literature has conceptualized two types of participation behavior: co-production and value co-creation. However, there is a dearth of knowledge concerning both the antecedents of customer co-creation behavior and the outcomes of such behavior in relation to customer-perceived value and loyalty. Anchored in the trust-commitment theory, the present research (a) examines the effect of how a customer's trust in the service personnel could affect his/her cooperative behavior over the service design and delivery processes; and (b) investigates how the potential impact of a customer's trust in service personnel on his/her co-design and co-delivery behavior could be made contingent upon the customer's trust in the service brand and the types of high- versus low-customer-contact service contexts. Filling the aforementioned research gaps, the present research contributes to advance our knowledge of the roles played by trust at different levels of analysis in facilitating customer participation behavior and improving our appreciation of the customer contact service contexts when designing the service organization for maximizing service value and sustaining brand loyalty over time. 相似文献

Abstract Consider a portfolio containing number of risk classes. Each class has its own demand function, which determines the number of insureds in this class as a function of the premium. The insurer determines the premiums based on the number of insureds in each class. The “market” reacts by updating the number of the policyholders, then the insurer updates the premium, and so on. We show that this process has an equilibrium point, and then we characterize this point. 相似文献

While the beneficial impacts of supplier and customer integration are generally acknowledged, very few empirical research studies have examined how an organization can achieve better product performance through product innovation enhanced by such integration. This paper thus examines the impact of key supplier and customer integration processes (i.e., information sharing and product codevelopment with supplier and customer, respectively) on product innovation as well as their impact on product performance. It contributes to existing literature by asking how such integration activities affect product innovation and performance in both direct and indirect ways. After surveying 251 manufacturers in Hong Kong, this study tested the relationships among information sharing, product codevelopment, product innovativeness, and performance with three control variables (i.e., company size, type of industry, and market certainty). Structural equation modeling with correlation and t‐tests was used to test the hypothesized research model. The findings indicate a direct, positive relationship between supplier and customer integration and product performance. In particular, this study verifies that sharing information with suppliers and product codevelopment with customers directly improves product performance. In addition, this study empirically examines the indirect effects of supplier and customer integration processes on product performance, mediated by innovation. This has seldom been attempted in previous research. The empirical findings show that product codevelopment with suppliers improves performance, mediated by innovation. However, the sampled firms cannot improve their product innovation by sharing information with their current customers and suppliers as well as codeveloping new products with the customers. If the adoption of supplier and customer integration is not cost free, the findings of this study may suggest firms work on particular supplier and customer integration processes (i.e., product codevelopment with suppliers) to improve their product innovation. The study also suggests that companies codevelop new products only with new customers and lead users instead of current ones for product innovation. For managers, this study has demonstrated that both information sharing and product codevelopment affect performance directly and indirectly. Managers should put more emphasis on these key processes, especially when linked with product innovation. Managers should consider involving their suppliers and customers in the early stages of design. Information sharing with suppliers is also important in product development. As suggested by this study, extensive effort on supplier and customer integration should be made to directly augment current product performance and product innovation at the same time. 相似文献
