均匀圆阵的测向模糊研究

在高分辨阵列测向系统中,均匀圆阵(UCA)是一种广泛使用的阵列结构。利用均匀圆阵的阵列流形的微分几何作为分析工具,对实际中常用的几种均匀圆阵的测向模糊进行了大量的计算机仿真试验,定量地给出了这些阵列的测向模糊方向和相应的秩,揭示了均匀圆阵的测向模糊性能与其阵元数和孔径之间的关系,得出了一些有实际意义的结论。这对工程应用时均匀圆阵的选择和构造具有很强的参考价值和指导意义,可以避免系统设计的盲目性和随意性。

A process leading to strategic alliance outcome: The case of IT companies in China,Japan and Korea

Although theories and research have provided valuable information on strategic alliance, it still seems difficult for practitioners to overview the process and subsequent outcomes of strategic alliance in a single frame. This is because the conditions of alliance are different from one alliance to another, which makes it difficult for practitioners to apply existing research findings to their own cases. One of the ways to overcome such difficulties in practical application would not be focusing on alliance processes with unique or idiosyncratic features of each alliance but instead focusing on elements that exist in most alliances. To find out the process that leads to the outcome in strategic alliance that is easily applicable for practitioners, the current study measured the behavioral direction and relational outcomes of strategic alliance based on benefit and risk perception in information technology (IT) companies in China, Japan and South Korea. Results show that firms set the direction and the intensity of their participation in alliance based on benefit and risk perception. Specifically, while perceived benefits promoted active participation in alliance, perceived risks increased protective participation in alliance. Also, these behavioral directions predicted the relational outcome in strategic alliance such that while active behavioral orientation predicted commitment to the relationship with the partner firms, protective behavioral orientation led to dissolution of the relationship. The present study provides useful insights for strategy associates, and evoke more various and detached academic approaches in the field of strategic alliance discussions.

Vacancy posting, job separation and unemployment fluctuations

What is the relative importance of hiring and separation in driving unemployment fluctuations? This paper presents a framework to decompose the moments of unemployment and study the respective contributions of vacancy posting, a measure of firms’ hiring efforts, and separation. Separation accounts for about 40% of unemployment's variance, compared to 60% for vacancy posting, and contributes to about 60% of unemployment steepness asymmetry, the fact that unemployment increases faster than it decreases. Further, while vacancy posting is, on average, the most important contributor of unemployment fluctuations, the opposite is true around business cycle turning points, when separation is responsible for most of unemployment movements.
