地位竞争动机对个体知识共享行为的影响

知识共享行为是学术界和企业界关注的焦点，虽然以往文献从多个角度和层次研究了组织中的知识共享行为，但忽视了地位竞争动机对个体知识共享决策的内在作用机制。基于地位竞争动机差异，将个体地位动机区分为支配型和威望型，以职场排斥为中介变量、组织公平氛围为调节变量，构建地位竞争动机对知识共享行为的影响过程模型，基于13个组织630套上下级配对样本数据进行实证检验。结果显示，支配型地位竞争动机负向影响知识共享行为，威望型地位竞争动机正向影响知识共享行为，职场排斥、组织公平氛围分别发挥中介效应和调节效应。结果为知识共享领域研究提供了新的视角和框架，揭示了地位竞争动机对知识共享促进和抑制作用的两面性，对企业管理实践有一定的现实意义。     

A Novel Compact Cat Swarm Optimization Based on Differential Method

ABSTRACT

A compact cat swarm optimization scheme (cCSO) is proposed in this paper, which is designed to solve application domains plagued with limited memory and less-computation power, as a member of cat swarm optimization algorithms (CSO), it composes of two sub-modes, i.e., tracing and seeking modes, so it keeps the same search logic of CSO. On the other hand, cCSO inherits the main feature of compact algorithms, a normal probabilistic model is used to represent the population of solutions instead of processing an actual population, which ensures the cCSO to have the modest memory requirement. The updating vector for the probabilistic model provides a clear moving direction for cats in next step. A cat without historical position and velocity is applied in the algorithm. When the cat is in seeking mode, it employs a differential operator to update the cat’s position, which makes it possible for the cat to have multiple searching directions. Experimental results show that cCSO has pretty performance compared with respect to some population-based testing benchmarks. And it also shows superior performance in convergence rate to some compact optimization algorithms. The case study of gray image segmentation proves that it suits for solving the optimization problem by limited hardware.     

Private School Usage in Australia 1975–2010: Evidence from the Household Expenditure Surveys

The use of private schools in Australia has increased greatly since the 1970s. This article shows that most of the growth has been concentrated in attendance at low-fee schools, while the growth in using high-fee schools has been modest. Furthermore, the increase has occurred for households at all income levels, for both single-parent and two-parent households, for households of all sizes, and irrespective of whether the household reference person is born in Australia or elsewhere. However, increasing income and changes in household composition can account only for a small part of the trend.     

新零售下社区生鲜配送模式的综合评价

新零售模式下社区生鲜“最后500m”的冲刺已成为生鲜农产品快速配送的关键问题。基于目前已有的配送模式:“社区+便利店”模式、第三方配送以及众包模式,通过层次分析法从服务水平、配送成本、客户体验三个方面对三种配送模式进行量化分析,得出每种配送模式在各层次的权重。研究结果表明配送中降低配送成本是关键,减少货物赔损率、提高客户满意度才能实现有效率的配送。     

Selective disclosure and the role of Form 8-K in the post-Reg FD era

We investigate the impact of Form 8-K filings on cross-firm differences in analysts’ private or idiosyncratic information in the post-Reg FD era. Using firms’ connections to the investment community to identify the likelihood of selective disclosure, we document differences in analysts’ idiosyncratic information arising from selective disclosure before 8-K filings. While filings of 8-Ks pursuant to Reg FD attenuate the link between connections and analysts’ idiosyncratic information, they do so only after selective disclosures have already resulted in some analysts having better private information. In addition, the connections continue to facilitate private information search after the filings of non-Reg FD-specific 8-Ks.     

Effects of investor tax heterogeneity on stock prices and trading behaviour around the ex-dividend day: the case of Australia

Using a sample of Australian stocks during the 1996–2014 period, this study examines how tax heterogeneity between domestic and foreign investors affects trading behaviour and stock prices around the ex-dividend day. Domestic investors prefer dividends and tend to buy stocks cum-dividend and sell them ex-dividend whereas foreign investors tend to trade in the opposite direction. Abnormal trading turnover increases with tax heterogeneity. Moreover, stocks with a larger domestic investor base are associated with a higher price drop-off ratio on the ex-dividend day and higher market value of franking credits. Overall, our findings support the dynamic dividend clientele hypothesis.
