This study examines the mediating effect of international alliances for the relationship between TMT (top management team) job‐related diversity (educational, functional background, outside industry experience and international exposure) and firm internationalization. We argue that firms with greater TMT diversity will use more international alliances, resulting in higher firm internationalization. Based on a sample of 226 US firms during the period 1988–1994, we find that international alliances partially mediate the relationship between TMT international exposure diversity and firm internationalization. However, we do not find international alliances to mediate the relationships between other forms of TMT diversity and firm internationalization. We discuss implications and directions for future research. 相似文献

This study empirically explores international and intersectoral R&D spillover effects on the total factor productivity growth of manufacturing and nonmanufacturing sectors based on a pooled time-series data set of 14 OECD economies and 3 East Asian economies—Korea, Singapore, and Taiwan. The study finds that foreign manufacturing R&D has strong influence on domestic productivity growths of both sectors and that domestic manufacturing R&D has a substantial intersectoral R&D spillover effect on domestic nonmanufacturing productivity growth. The social rates of return to manufacturing R&D are estimated to be two to six times greater than the private rates of return. 相似文献

在具有代表意义却处于不同境遇的俄国和西欧的无产阶级革命中,都提出了在我们今天仍有重大意义的历史课题:即意识形态与无产阶级革命的关系问题.事实上,马克思最先对无产阶级的意识形态进行了隐晦的解答,而列宁和卢卡奇、葛兰西又于不同地域赋予了这一问题以实践维度的应答,其具有的异路与互补特征为当时的无产阶级革命增添了光辉的一页,也为马克思主义的意识形态性创设了存在的价值. 相似文献

This paper describes procedure for constructing a vector of regression weights. Under the regression superpopulation model, the ridge regression estimator that has minimum model mean squared error is derived. Through a simulation study, we compare the ridge regression weights, regression weights, quadratic programming weights, and raking ratio weights. The ridge regression procedure with weights bounded by zero performed very well. 相似文献

Li et al. (2007) developed an estimation method for quantile functions in a reproducing kernel Hilbert space for complete data, and Park and Kim (2011) proposed an estimation method using the ε-insensitive loss. This article extends these estimation methods to left-truncated and right-censored data. As a measure of goodness of fit, the check loss and the ε-insensitive loss were used to estimate the quantile function. The ε-insensitive loss can shrink the estimated coefficients toward zero; hence, it can reduce the variability of the estimates. Simulation studies show that the estimated quantile functions based on the ε-insensitive loss perform slightly better when ε is adequately chosen. 相似文献

The concept of sloperotaiability with equal maximum directional vari ance for second order response surface models is introduced as a new design property. This requires that the maximum variance of the estimated slope over all possible directions be only a function of p, which is the distance from the design originif is shown that a rotatable design satisfies this property Also, minimization of tiie maximum variance of the estimated slope over all possible directions is proposed as a new design optirnality criterion, and op¬timal designs are called slope-directional minirnax designs. For the class of cquiradial designs, the slope-directional minirnax designs are compared with D— optimal designs. 相似文献
