ABSTRACTWe present a group dynamics model that shows knowledge integration as a process occurring over time. As each individual in the group contact others, his own knowledge changes, and over time the collective knowledge is obtained. This allows modeling knowledge diffusion in a social network and while the models presented in this paper are not competitive in that area, they approach the problem from previously unconsidered direction. We test the behavior of the model in a multi-agent simulation and we test a simple advertisement campaign in a social network. We provide discussion of elements needed for making model more competitive. 相似文献

A variety of recent leader development programs have focused on improving leaders' emotional and interpersonal competencies. Decades of leadership research suggest that these “people skills” are crucial for leader effectiveness. This paper reviews the history of these leader development programs as well as research on emotional and interpersonal competencies. Suggestions for grounding leader development programs in sound research on emotional and social competencies, as well as an agenda for future research on the development of leader emotional and interpersonal skills, are provided. 相似文献

文章概述了90年代以来理论界在劳动力价值的构成范围、劳动力价值的实现与按劳分配、智力劳动力工资的理论解释问题上提出的许多新的观点并作出了简要的评论。随着社会主义市场经济的发展,还有许多问题,如:劳动力价格背离价值的理论问题,劳动力价格高于价值的现实问题,劳动力的特殊性对劳动力价值的影响等值得深入探讨,以使劳动价值论更好地指导社会主义市场经济实践。 相似文献

The expression “the bell curve” designs both a kind of statistical distribution and the title of a famous and controversial
book by Herrnstein and Murray. The first is so attractive that the second refers to it to give more credibility to its questionable
theories on intelligence. The point is that, during the 20th century, the bell curve has assumed a more and more important
role in psychological research and practice and have become both a reality and a myth. In the first case (reality) we can
assist to appropriate applications of a real useful statistical concept. In the second (myth) we can have two kinds of attitudes:
one attitude is typical of those researchers who search for normality in all their data and variables, just as Parsifal used
to search for the Holy Graal (we call this “the Parsifal attitude”); the other is typical of those researchers who give normality
for granted and act as if it were a Platonic Idea (we call this “the Plato attitude”). The article discusses the role of the
normal distribution in psychological research and practice and shows how it can be dangerous to treat the bell curve as a
God or an Idol. 相似文献

理论创新与市场价值论 总被引:2,自引:0,他引:2

市场经济取代计划经济具有客观必然性,市场经济体制下只能由市场决定(初次)分配,每个劳动力、每项产出的价值只能由市场(社会需求)来认定,凡是有需要(需求)的,即是有价值的,没有需求的供给(劳动)是无价值的。只有(活)劳动才创造价值的观点既不符合事实,也不符合逻辑。创造财富的所有要素均有各自的贡献份额,劳动价值论即使在计划经济条件下都不具有可操作性。劳动价值论必须转变为市场价值论。 相似文献

青年教师的教书职业第一年如期达到熟悉大学教学环节,掌握大学教学规律,适应大学教学活动的目的,不仅取决于对青年教师培训,还取决于专业辅导教师有心智地对青年教师进行辅导的过程。专业辅导教师要为青年教师创造一个有利于他们提高教学水平和能力的、安全的、宽松的教学环境,要推动青年教师充分发挥主观能动性,积极主动地完善自己的综合素质。所以,专业辅导教师不仅要具备较强的专业教学能力而且要有心智素质:“人际关系能力”和“自省能力”。这样他才能够做到既能读懂自己又能读懂青年教师,圆满完成对青年教师的辅导工作。 相似文献

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year. 相似文献

This paper proposes a spatial structural decomposition analysis to measure the effects of the changes in intra- and inter-country linkages on the embodied energy demand in the concerned country. For the empirical analysis, we have used the China- Japan inter-country input–output tables for 1985 and 1990, expressed in constant prices of 1990. The empirical results reveal that (1) at least for the period between 1985 and 1990, the effects of the non-competitive input structural changes in China on the primary energy requirements of Japan were negligible, and (2) the contribution of the Japanese final demand shifts on the total change in Chinese primary energy demand was 40 times larger than that of the Chinese final demand shifts on the primary energy requirements of Japan. The Japanese policy makers should concentrate on the energy impacts of the changes in the domestic production structure rather than the changes in the Chinese production structure. 相似文献
