合作共赢发展与个体工作绩效:知识隐藏与证明目标导向的作用

如何抑制个体知识隐藏行为,推动企业发展与个体职业合作共赢有利于组织创新,基于资源保存和目标导向理论,以知识隐藏为中介变量,以证明目标导向为调节变量,构建合作共赢发展对个体工作绩效影响的有调节中介作用模型; 通过281份有效问卷的数据收集、因子分析以及分层回归等,研究中国情境下合作共赢发展通过知识隐藏对个体工作绩效的作用机理,考察证明目标导向的边界作用。研究认为,合作共赢发展对个体工作绩效有显著正向影响,知识隐藏在合作共赢发展与个体工作绩效之间有显著中介作用,证明目标导向调节合作共赢发展和知识隐藏对个体工作绩效的直接作用,证明目标导向调节合作共赢发展通过知识隐藏对个体工作绩效的间接作用; 因此,企业应重视创建上下联通、利益相关的员工职业发展体系,鼓励员工的知识共享行为,营造能够激发员工证明目标导向的组织环境。     

穗重型杂交中稻冈优501产量构成分析

通过对冈优501五年16个试点的主要产量性状及产量的分析表明：有效穗与产量、着粒数、实粒数、千粒重呈负相关关系。尤其与着粒数、实粒数高度负相关,穗数与粒数矛盾突出。粒数、粒重与产量呈正相关关系。适当控制群体,促进个体发育,有利于发挥穗重型品种多花多实的产量潜能。     

Generalized Leverage and its Applications

The generalized leverage of an estimator is defined in regression models as a measure of the importance of individual observations. We derive a simple but powerful result, developing an explicit expression for leverage in a general M -estimation problem, of which the maximum likelihood problems are special cases. A variety of applications are considered, most notably to the exponential family non-linear models. The relationship between leverage and local influence is also discussed. Numerical examples are given to illustrate our results

理性为什么被邪恶击败?——读戈尔丁的《蝇王》

《蝇王》自1954年发表以来,大多数有关评论集中讨论了该书的性恶论及其对现代世界的哲学、社会和政治含义。本文在进一步探讨《蝇王》的性恶论主题的基础上,着重分析了它的理性和赎救主题,指出被一般评论所忽视的人物形象西蒙不仅是一个传统意义上的救世主形象,而且这一形象蕴含着现代人理性的泯灭和理想人格的隐退乃至消逝;《蝇王》的根本寓义并不在于人性邪恶的本身,而在于同邪恶抗争的必要性和紧迫性。     

关于社会福利制度的深层次思考

效率和公平是社会福利的两大准则 ,整个人类历史可以说就是一个不断追求效率和公平的历史 ,而其中针对社会弱势群体进行的收入和服务保障更是一个超社会形态的课题 ,是一个关乎人类社会福利的重要问题。针对中国的实际情况 ,本文中所讨论的社会福利制度被限定在“剩余福利模式”上。在对中外社会福利制度的起源及其理论发展进行考察的基础上 ,作者指出 :社会福利的提供应是制度化的政府职责 ,它的实施不仅能有效地保护社会弱势群体 ,还有利于全社会秩序的稳定和经济增长目标的实现 ;在中国目前财政收入相对不足的情况下 ,政府应充分利用社会资源、调动社会力量、推进立法、加紧培育行业组织和非赢利社会组织 ,以达到完善社会福利制度、有效保护社会弱势群体之目的。     

Optimization Model and Algorithm for Crew Management During Airline Irregular Operations

Airline irregular operations have long been a realm where human experience and judgement are the most important tools to utilize. Crew management during irregular operations is usually the bottleneck of the whole system-recovering process due to complicated crew schedules and restrictive crew legalities as well as the size and scope of the hub-and-spoke networks adopted by major carriers. A system-wide multi-commodity integer network flow model and a heuristic search algorithm for the above purpose are presented and discussed in this paper. The computational experiences show that the algorithm is efficient enough to solve problems of realistic size and also has the flexibility to accommodate practical business requirements.     

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.
