The authors examine theory and research on team intimacy and team cohesion, and argue that the two have often been confused, merged, and used interchangeably in recent theoretical, empirical, and applied work on team effectiveness. The authors propose distinct definitions to clarify and distinguish between team intimacy and team cohesion, and suggest areas that will aid research and application. Their examination provides a framework for understanding the inconsistent findings in team effectiveness and team building research and thus helps to improve human resource management (HRM) interventions. 相似文献

I see a big growth potential for the US and Chinese biotechnology partnerships for the next years. US biotechnology sector is generating already more than $50 billion dollars. Chinese bio-technology will grow in the next 20 years to more than 11 billion yuan (US 1.33 billion) annually. 相似文献

This study examines the performance of a trading strategy based on the prediction of firms concurrently reporting a positive
earnings change and meeting analysts’ earnings forecasts. The evidence indicates that a model predicting both earnings thresholds
concurrently can yield excess returns that are incremental to predicting only one earnings threshold. Further, I find that
the prediction of forecast errors is relatively more important than predicting earnings changes as the incremental benefit
from predicting earnings changes concurrently with forecast errors is small relative to a model that predicts only forecast
errors. The results hold while controlling for various risk factors and known anomalies. 相似文献

The increased trading in multi-name financial products has required the development of state-of-the-art multivariate models. These models should be computationally tractable and, at the same time, flexible enough to explain the stylized facts of asset log-returns and of their dependence structure. The popular class of multivariate Lévy models provides a variety of tractable models, but suffers from one major shortcoming: Lévy models can replicate single-name derivative prices for a given time-to-maturity, but not for the whole range of quoted strikes and maturities, especially during periods of market turmoil. Moreover, there is a significant discrepancy between the moment term structure of Lévy models and the one observed in the market. Sato processes on the other hand exhibit a moment term structure that is more in line with empirical evidence and allow for a better replication of single-name option price surfaces. In this paper, we propose a general framework for multivariate models characterized by independent and time-inhomogeneous increments, where the asset log-return processes at unit time are modeled as linear combinations of independent self-decomposable random variables, where at least one self-decomposable random variable is shared by all the assets. As examples, we consider two general subclasses within this new framework, where we assume a normal variance-mean mixture with a one-sided tempered stable mixing density or a difference of one-sided tempered stable laws for the distribution of the risk factors. Particular attention is given to the models' ability to explain the asset dependence structure. A numerical study reveals the advantages of these new types of models. 相似文献

The lack of comparative evaluation research on organizational-effectiveness models is the primary focus of this discussion. Problems in conceptually and operationally defining evaluation models, such as those in the goal and system model classes, are the proposed reason for this lack of comparative research. In this paper, goal and system models are formally defined in terms of their historical origins, underlying criteria and differing methods of application. A goal and system model classification continuum is also presented. Five comparative evaluation research questions are proposed and their implications for research are discussed. From a theoretical perspective this paper attempts to go beyond the sound foundation laid by Campbell (1977) in his discussion of these two schools of thought on organizational effectiveness. 相似文献

This paper investigates the phenomenon of sale and leasebacks as one way in which firms may use financial contracts to rearrange their organizational architecture. A theoretic model links the length of initial leaseback period to incentives to make noncontractible future investments in the lease relationship and predicts that firms choose shorter leases when landlords make relatively important investments. Using a sample of 71 sale and leaseback events from the 1990s, we document a significant mean abnormal return of 1.3% for shareholders of seller/lessee firms announcing relatively short leasebacks. The evidence suggests that firms may use sale and leasebacks to optimize their claims to real estate. 相似文献

In this era of increased global cooperation, a growing number of negotiators conduct business in multiple countries and, therefore, need access to a systematic comparison of negotiating tendencies across a wide range of countries. Empirical work systematically comparing variations across a range of cultures is scarce. A comparative analysis of negotiating tendencies in five countries is presented. This study establishes the utility of the [Salacuse, J. (1998) Ten ways that culture affects negotiating style: Some survey results. Negotiation Journal, 14(3): 221–235] framework in identifying country differences across five countries, representing five cultural clusters. Significant differences in negotiation orientations both between and within cultures were revealed at a level of complexity not found in previous empirical studies. 相似文献
