文化差异对美资跨国公司总部知识转移影响研究

摘要：跨国公司内部知识跨国界转移的影响因素很多。本文以美资跨国公司为例,重点分析公司总部的知识转移能力、知识转移意愿、显性知识和社会化知识转移渠道丰富性对向在华子公司转移知识效果的影响。本文还借鉴Hofstede的民族文化模型,重点分析权力距离和男性-女性主义两个纬度上的文化差异对总部知识传播能力-知识转移渠道丰富性-知识转移效果之间关系的调节作用,并据此提出相应的提高跨文化知识转移效果的措施。

环境规制下中国农业技术效率的区域差异与影响因素——基于农业碳排放与农业面源污染双重约束的视角

低碳发展和绿色发展是农业可持续发展的核心内容,将农业碳排放与农业面源污染纳入统一分析框架,分别从省域与区域层面探讨中国农业技术效率的区域差异,并对农业技术效率的影响因素进行分析.结果 表明,中国近60％省域的农业技术效率未达到生产前沿;东部地区效率值最高,中部地区最低;东部沿海地区农业技术效率处于最优生产前沿面,长江中游地区处于较低水平;粮食主销区效率值最高,粮食主产区最低;农业技术效率与经济发展水平呈正U型关系,互联网发展水平和农业财政支持对农业技术效率有显著促进作用,而种植结构存在负向影响.

Probability Density Function Method for Observing Reconstructed Attractor Structure

Probability density function (PDF) method is proposed for analysing the structure of the reconstructed attractor in computing the correlation dimensions of RR intervals of ten normal old men. PDF contains important information about the spatial distribution of the phase points in the reconstructed attractor. To the best of our knowledge, it is the first time that the PDF method is put forward for the analysis of the reconstructed attractor structure. Numerical simulations demonstrate that the cardiac systems of healthy old men are about 6 - 6.5 dimensional complex dynamical systems. It is found that PDF is not symmetrically distributed when time delay is small, while PDF satisfies Gaussian distribution when time delay is big enough. A cluster effect mechanism is presented to explain this phenomenon. By studying the shape of PDFs, that the roles played by time delay are more important than embedding dimension in the reconstruction is clearly indicated. Results have demonstrated that the PDF method represents a promising numerical approach for the observation of the reconstructed attractor structure and may provide more information and new diagnostic potential of the analyzed cardiac system.     

新FRP技术加固钢筋混凝土矩形柱改善延性的试验研究

Reinforced concrete （RC） columns lacking adequately detailed transverse reinforcement do not possess the necessary ductility to dissipate seismic energy during a major earthquake without severe strength degradation. In this paper, a new retrofit method, which utilized fiber-reinforced plastics （FRP） confinement mechanism and anchorage of embedded bars, was developed aiming to retrofit non-ductile large RC rectangular columns to prevent the damage of the plastic hinges. Carbon FRP （CFRP） sheets and glass FRP （GFRP） bars were used in this test, and five scaled RC columns were tested to examine the function of this new method for improving the ductility of columns. Responses of columns were examined before and after being retrofitted. Test results indicate that this new composite method can be very effective to improve the anti-seismic behavior of non-ductile RC columns compared with normal CFRP sheets retrofitted column.     

Personal Review： Sources of sulfide in waste streams and current biotechnologies for its removal

Sulfide-containing waste streams are generated by a number of industries. It is emitted into the environment as dis- solved sulfide (S2- and HS-) in wastewaters and as H2S in waste gases. Due to its corrosive nature, biological hydrogen sulfide removal processes are being investigated to overcome the chemical and disposal costs associated with existing chemically based removal processes. The nitrogen and sulfur metabolism interacts at various levels of the wastewater treatment process. Hence, the sulfur cycle offers possibilities to integrate nitrogen removal in the treatment process, which needs to be further optimized by appropriate design of the reactor configuration, optimization of performance parameters, retention of biomass and optimization of biomass growth. The present paper reviews the biotechnological advances to remove sulfides from various environments.     

Expertise Reversal Effect and Its Implications for Learner-Tailored Instruction

The interactions between levels of learner prior knowledge and effectiveness of different instructional techniques and procedures have been intensively investigated within a cognitive load framework since mid-90s. This line of research has become known as the expertise reversal effect. Apart from their cognitive load theory-based prediction and explanation, patterns of empirical findings on the effect fit well those in studies of Aptitude Treatment Interactions (ATI) that were originally initiated in mid-60s. This paper reviews recent empirical findings associated with the expertise reversal effect, their interpretation within cognitive load theory, relations to ATI studies, implications for the design of learner-tailored instructional systems, and some recent experimental attempts of implementing these findings into realistic adaptive learning environments.
