随着知识进步信息增长,现实决策环境日趋复杂.因决策人的有限理性所导致的决策不确定问题亟需解决.知识发现是解决不确定性问题的有效方法.基于案例推理和粗糙集是从数据中挖掘知识的良好工具.因此将粗糙集应用于基于案例推理,提出基于粗糙案例推理的在线自我学习决策方法.文中设计了决策模型和算法,并以应用实例对该方法的合理性和有效性予以说明. 相似文献

主并企业对被并企业的控制会影响并购绩效,而企业的各种利益相关者对于企业并购的态度即并购合法性会对并购后控制与并购绩效之间的关系产生影响。基于123个样本实证分析得到如下结论:主并企业对被并企业的非正式控制程度对主并企业的并购绩效具有显著积极作用,而正式控制程度与并购绩效之间没有显著相关性;并购的外部合法性对并购后正式控制与并购绩效之间的关系具有显著的正向调节作用,而并购的内部合法性对并购后非正式控制与并购绩效之间的关系具有显著的负向调节作用。研究结论对于中国企业的并购后决策以及如何实现并购目标具有理论指导价值。 相似文献

基于并购的开放式创新对企业自主创新的影响——南汽并购罗孚经验及一般启示 总被引:8,自引:0,他引:8
作为探索性研究,本研究的讨论主要集中于基于并购的开放式创新对于企业自主创新的影响。在理论层面,本研究较深入地探讨了"开放式创新"与"自主创新"的背景及内涵,并构建联系、比较异同。基于2005年以来南汽集团对罗孚公司并购及此后发展的案例,本研究深入回顾了并购全程及后续项目进展,进而讨论了本次基于并购的开放式创新实践对南汽发展自主创新能力的作用。结合案例,本研究结果初步表明:基于并购的开放式创新对企业自主创新有可能产生积极的影响,发生条件是:(1)被并购方知识积累大于并购方或与并购方原知识积累形成互补;(2)并购方有能力整合来自被并购方的创意,使外部创意内化为以开发新产品为表征的内生创新力量。 相似文献

《The Leadership Quarterly》2020,31(2):101404
Evolutionary perspectives are part of any comprehensive explanation of leadership and, more generally, hierarchy formation in groups. This editorial describes contributions to a special issue on the theme of “The evolution and biology of leadership: A new synthesis”, and we reach four main conclusions. First, leadership has been a powerful force in the biological and cultural evolution of human sociality. Humans have evolved a range of cognitive and behavioral mechanisms (adaptations) that facilitate leader-follower relations, including safeguards against overly dominant leaders. Second, how these adaptations interact with local ecological and cultural contexts produces cultural variation in leadership preferences, and in the structure of human organizations more broadly. Third, an evolutionary perspective creates consilience between the social and natural sciences, by integrating leadership theory from diverse fields such as biology, psychology, neuroscience, anthropology, economics, and political science. Fourth, evolutionary approaches – and specifically the collection of articles in this theme issue – produce and test novel hypotheses, such as regards (i) the critical role of leadership in cooperation, (ii) the importance of contextual factors in leader emergence and effectiveness, (iii) interactions between genetic and cultural influences on leadership, and (iv) obstacles and opportunities for women leaders. 相似文献

Abstract The thoughtful behavior analysis of organizational leadership and resistance to change by Goltz and Hietapelto (2002) inspired this follow-up article. Goltz and Hietapelto propose that organizational power is determined by the magnitude, frequency, and quantity of consequences under a person's control, and that people resist change when their consequence control is threatened. This presentation extends the Goltz and Hietapelto article by describing 14 distinctions between management and leadership, and offering 16 guidelines for effective leadership that involve more than consequence control. Thus, while managers obtain their influence by controlling other peoples' consequences, leaders go beyond consequence control to benefit the behaviors and attitudes of their colleagues and coworkers. The leadership guidelines are founded on behavioral research and are relevant and practical for any organizational employee, even those who have only minimal influence on the meaningful consequences of their own and others' work life. 相似文献
