External knowledge search,absorptive capacity and radical innovation in high-technology firms

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation.     

伸展构造背景下倾角资料的构造解释

系统总结了在伸展构造背景下，导致反映构造特征的地层倾角模式复杂化的多种因素。沉积相的不同、岩性变化、井眼状况和测井作业时间等多种因素都可能使地层倾角资料复杂化。进一步指出在拉张盆地中，进行倾角资料的构造解释，必须了解其构造样式的多样性和复杂性，解释存在的多解性。重点解剖了铲式断层在横剖面情况下，对于不同构造位置下的倾角模式。详细分析了一个倾角模式对应多种构造样式的倾角构造解释实例。倾角资料的构造解释应是综合解释，既要综合井筒的相关地质资料，又要综合测井与地质知识，还必须考虑综合地震资料。

明代金湜、张珹出使朝鲜与《甲申皇华集》述论

天顺八年，金湜、张城作为正、副使赴朝鲜颁明宪宗登极诏。在朝鲜期间，他们充分发挥自己的才艺，与朝鲜文臣赓酬唱和，留下了许多诗文。朝鲜为了表示事大之诚，更为了显示本国的文雅之关，将这些诗文辑录刻印，即《甲中皇华集》。学界关于这一问题，尚未展开探讨，文章探讨了《甲中皇华集》的成因，内容方面的特色及双方唱和的竞争意识、使臣形象的差异问题，以求对研究中朝文学关系有所裨益。     

印蒂与浮士德:一对超越时空的精神孪生儿——论《无名书》与《浮士德》的精神联系

作为一名潜隐达半个世纪的中国现代作家,无名氏与歌德之间存在着难以掩盖的距离.然而,对比《无名书》中的印蒂与《浮士德》中的同名主人公,我们却能清晰地触摸到二者在对人生终极意义的追寻与探索上的深层的精神联系.     

论现代企业经营思想

企业行为受其经营思想的支配,企业的经营思想取决于企业所处的客观环境。在市场经济与现代企业制度的约束下,企业普遍应树立的经营思想有:守法观念、效益观念、用户观念、创新观念、竞争观念和战略观念。各种观念应当互为配合,形成一个有机的整体。     

Marginal and association regression models for longitudinal binary data with drop‐outs: A likelihood‐based approach

Longitudinal data often contain missing observations, and it is in general difficult to justify particular missing data mechanisms, whether random or not, that may be hard to distinguish. The authors describe a likelihood‐based approach to estimating both the mean response and association parameters for longitudinal binary data with drop‐outs. They specify marginal and dependence structures as regression models which link the responses to the covariates. They illustrate their approach using a data set from the Waterloo Smoking Prevention Project They also report the results of simulation studies carried out to assess the performance of their technique under various circumstances.     

要着力加快统计方法制度改革

改革开放以来,我国的统计工作得到了长足发展,统计事业蒸蒸日上。尽管如此,相对于国际国内形势的发展变化,我国的统计方法制度改革仍显滞后,致使统计工作在很多方面不适应形势发展要求,统计事业的进一步发展面临着更为严峻的挑战,统计方法制度改革工作任重道远。一、统计工作面
