动态能力、双元学习与新产品开发绩效

基于动态能力和组织学习理论,本文以双元学习为调节变量,构建了技术能力、营销能力影响新产品开发绩效的理论模型,并提出相应假设。213家中国企业的实证结果表明,技术能力、营销能力与新产品开发绩效的关系因学习方式的不同而有所差异。而且,双元学习平衡对于技术能力和营销能力的效用具有相反的调节作用。

Let Our Souls Keep Up With Our Pace

The National Museum witnessed record visitors during the na- tional holiday. The deputy cu-rator, Chen Lvsheng, is excited to see such a change. He looks forward to one day when public cultural spaces like museums and galleries would become a city＇s living room tot guests, and a life- time classroom for every person. None- theless, Chen is not expecting quick re- suits, because “ cultural development requires time and education”.     

“弱水”与“昆仑山”

<正>鲁迅在杂文《热风·随感录六十二恨恨而死》中写道,对于那些一味愤愤不平、自暴自弃以致"恨恨而死"的人们,"应该趁他们活着的时候问他:诸公!您知道北京离昆仑山几里,弱水去黄河几丈     

孩子的来历与归属——神话传说背后的上古风习

一女娲是中国古代最著名的女神之一,其神奇之处一是治水,二是补天,三是造人。她的造人完全自力更生,无须外力,乃是典型的＂孤雌生殖＂。《太平御览》卷七十八引《风俗通》云：     

Shoe drop reduction influences the lower limb biomechanics of children tennis players during an open stance forehand: A longitudinal study

Compared to traditional tennis shoes, using 0-drop shoes was shown to induce an immediate switch from rear- to forefoot strike pattern to perform an open stance tennis forehand for 30% of children tennis players. The purpose of the study was to examine the long-term effects of a gradual reduction in the shoe drop on the biomechanics of children tennis players performing open stance forehands. Thirty children tennis players participated in 2 laboratory biomechanical test sessions (intermediate: +4 months and final: +8 months) after an inclusion visit where they were randomly assigned to control (CON) or experimental (EXP) group. CON received 12-mm-drop shoes twice, whereas EXP received 8?mm then 4-mm-drop shoes. Strike index indicated that all CON were rearfoot strikers in intermediate and final test sessions. All EXP were rearfoot strikers in intermediate test session, but half the group switched towards a forefoot strike pattern in final test session. This switch resulted in a decreased loading rate of the ground reaction force (?73%, p?=?.005) but increased peak ankle plantarflexors moment (+47%, p?=?.050) and peak ankle power absorption (+107%, p?=?.005) for these participants compared with CON. Biomechanical changes associated with the long-term use of partial minimalist shoes suggest a reduction in heel compressive forces but an increase in Achilles tendon tensile forces.     

“放焰口”与盂兰盆节

鲁迅在《我的第一个师傅》一文中幽默地写到他“最初的先生”——绍兴长庆寺住持龙师父其人,说他平时很和气,也不念经,只有到了“穿起袈裟来做大和尚,或者戴上毗卢帽放焰口,‘无祀孤魂,来受甘露味’的时候”,才是“庄严透顶”的。     

对我国教育产业化发展的对策探讨

我国教育产业化发展,要先转变办教育的观念;改革教育发展单一投资的体制,形成多元投资的体制;教育发展要走产业化的道路;进一步开放留学生教育市场;积极发展民办教育,大幅度提高国家财富总增量;调整教育政策,正确引导有受教育需求者的教育投资方向,增大学生自由选择就读的学校、专业和教师。     

再论残疾人体育的意义

抛却残疾人体育的世俗意义,将之放到人类历史的大背景中,就会发现缺陷是伴随人的天然产物,但这并不是人类前进的阻碍.残疾人体育明确地指出了人类的意志是这一缺陷的克星,因此它另外的要告诫世人的是,卑劣的人性才是人类永远的痛.残疾人体育行为的本身开出了针对此种病痛的药方,团结一致,改劣从善,追求人类的生命自由和幸福.
