AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.     

CRIME AND POVERTY: A SEARCH‐THEORETIC APPROACH*

Numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities. We study this phenomenon in the context of a search‐equilibrium model, in which agents choose between formal employment and pursuing crime‐related activities (theft). Prior to their “occupational choices,” agents undertake costly schooling, raising their productivity. Crime acts, in essence, as a tax on human capital by affecting the probability that a worker's earnings (possessions) are subsequently appropriated. There are multiple equilibria. High crime, low levels of educational attainment, long spells of unemployment, and poverty are correlated across them.     

The Contingent Value of Responsive and Proactive Market Orientations for New Product Program Performance*

While the benefits of being market oriented are largely accepted, a group of scholars and managers remain skeptical. Marketing scholars have sought to counter the criticisms leveled against market orientation (MO) by arguing that it has both responsive and proactive dimensions. However, few studies have empirically examined the complexity of the effects of these dimensions on firm performance. Drawing on theories of resource‐based advantage and organizational search behavior, this article advances understanding by arguing that responsive and proactive market orientations have curvilinear effects on product development performance, that their interaction may be positively related to product development performance, and that their effects on new product program performance are moderated differentially by the organizational implementation conditions and marketing function power. Survey results of 175 U.S. firms indicate support for most of the hypotheses. Specifically, whereas responsive MO has a U‐shaped relationship with new product program performance, proactive MO has an inverted U‐shaped relationship with new product program performance. Contrary to the arguments presented here, the interaction of both orientations is negatively related to new product program performance. This study finds that both orientations are needed; however, new product program performance is enhanced when one is at higher level and the other is at lower level. Finally, responsive MO is only positively related to new product program performance under specific conditions such as when strategic consensus among managers is high. On the other hand, the positive effect of proactive MO on new product program performance is further strengthened when learning orientation and marketing power are high. Overall, this study suggests that the effects of responsive and proactive MO on new product program performance are more complex than previously theoretically argued and empirically examined.

战略无形资产、商誉与企业持续竞争优势

本文运用“资源基础论”分析了战略无形资产与企业持续竞争优势和超额利润之间的关系,论述了现行财务会计模式对战略无形资产信息的综合反映形式。认为商誉是现行财务会计模式对企业持续竞争优势的综合反映形式,其本质是在现行财务会计模式下无法单独入账的企业战略无形资产,商誉的性质实际上是战略无形资产性质的外在综合表现,外购商誉的本质是被收购企业未入账的战略无形资产,外购商誉的会计处理应该依据并购后被收购企业战略无形资产价值的增减变动情况来决定。

英汉否定的比较及其在翻译中的运用

英语中表达否定形式多样,如否定词、否定词缀、准否定词、否定句等.相对而言,汉语中表达否定的形式比较单一.本文试图通过比较英汉在否定表达上的异同,从英语表达否定的几种常见的方式入手,并结合英语例句加以剖析,揭示某些规律,指出在翻译时应视不同的情形来正确理解原文,从而使译文如实地反映原文的意义,且符合汉语的表达习惯.     

论《李尔王》中的伦理道德
