Despite the proactive efforts of many firms to combat gender bias within their organizations, societal prejudices still disadvantage women leaders and the firms who employ them. This external gender bias shapes outside stakeholder evaluations of women leaders’ efforts in various ways, and firms need strategies to cope with this external gender bias. We examine the conditions that might alleviate this burden of external bias and what women leaders and top executives can do to leverage these conditions—from a strategic positioning perspective—that will effectively allow female leaders to differentiate their work. To do this, we synthesize and build upon evidence that the external gender bias against women leaders diminishes when they lead in areas that are unconventional rather than mainstream. We then propose a two-step process based on (1) identifying the likely threat of external gender bias, which is stronger in some industry contexts than others, and (2) leveraging unconventionality to circumvent male prototypical comparisons, thereby reducing the hazards of external gender bias. 相似文献

建立产业共性技术研发外包博弈模型,从政府视角研究以共性技术产出最大化为目标的最优政府支持性研发外包合同,并对最优外包合同影响因素进行分析。研究表明:足够多的政府预算是共性技术政府支持性最优研发外包合同存在的前提,最优合同条款随政府预算的增大而增多,企业保留收益增大倒逼政府预算增加;企业最优知识技术投入与共性技术价值系数以及从研发中分享的收益份额正相关,与政府支付的固定研发费用负相关;政府最优知识技术投入与固定研发费用及单位投入成本系数负相关;企业最优投入与政府投入成本系数负相关,与政府投入对研发成功的贡献系数正相关,且企业最优投入随其研发能力的增强而加大。最后,根据研究结论,从政府预算、项目前景及支持性资源分配3个方面提出共性技术研发外包合同实施的政策建议。 相似文献

Recent research has developed an in-depth understanding of how workers change their jobs on their own to improve their performance and well-being, a process called job crafting. This research suggests that managers, coworkers, and organizations need a better understanding of how to manage job crafting to capitalize on its benefits and reduce costs. This article will help organizations diagnose the occurrence of job crafting, recognize the differences between goal-oriented approaches to job crafting as opposed to withdrawal-oriented avoidance job crafting, and identify the seven specific types of job crafting: work role expansion, social expansion, work role reduction, work organization, adoption, metacognition, and withdrawal. We conclude with recommendations for managers, coworkers, and organizations on how to diagnose and manage job crafting. 相似文献

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs. 相似文献

This paper reviews some recent blockchain‐based applications for information capture, distribution and preservation. As part of that review, this paper examines two key concerns with current blockchain designs for accounting and supply chain transactions: data independence and multiple semantic models for the same information distribution problem. Blockchain applications typically integrate database, application and presentation tiers all in the same ledger. This results in a general inability to query information in the ledger and other concerns. Further, since most applications appear to be private blockchain applications, there is a concern of agents needing to accommodate multiple blockchains depending on who their trading partners are and what they request. Finally, this paper uses a distributed database to design a ‘blockchain‐like’ system for virtual organizations. 相似文献

当前小体积远端射频单元(Remote Radio Unit,RRU)主要是皮站级别的Pico-RRU,其重量和体积仍然难以满足掌上型的要求。为此,采用高集成度的AD9361芯片来实现长期演进(Long Term Evolution,LTE)宽带收发信机功能,配合时钟同步模块、放大器模块和控制接口电路等一起构建低成本的掌上型RRU。主要解决了基于AD9516的时钟同步、低相位噪声设计和高灵敏度接收机设计三个技术难点,成功实现了掌上型、高性能、低成本的设计目标。整个RRU样机尺寸为18 cm×10 cm×2 cm,质量约500 g,量产成本千元以内。测试表明,该RRU下行误差向量幅度(Error Vector Magnitude,EVM)小于3%,优于3GPP要求的8%;10 MHz带宽时上行接收机灵敏度优于3GPP要求的-93.5 dBm。 相似文献
