Vygotsky’s sociocultural theory in the context of globalization

The article reviews the social-educational theorization of the early Soviet psychologist L. S. Vygotsky (1896–1934) in the light of the impact of communicative globalization in educational practice. Vygotsky proposed four “genetic domains” for investigating higher cognitive processes: the phylogenetic (humans undergoing natural evolution), the cultural-historical (social activity of humans), the ontogenetic (individual lifespan), and the microgenetic (immediate events). Vygotskian sociocultural theory is widely used in educational research, especially Vygotsky’s notion of mediated development via tools and signs. Since Vygotsky, communicative globalization has transformed educational potentials. Nevertheless, provided adjustments are made to Vygotsky’s genetic method to incorporate time-space compression, the mutual presence of the genetic domains, and the glonacal heuristic, Vygotskian theory continues to be useful in socially-situated investigations of educational development and transformation, and opens another way into the global, for example investigation of the role of global mediation in learning.     

试论手机媒体内容的信息网络传播权

当前,手机已成为继报刊、广播、电视、互联网之后被公众所广泛认知的"第五媒体",即手机媒体。手机媒体内容作为无可置疑的著作权法涵盖客体是手机媒体传播的主要对象,其信息网络传播权因手机媒体传播方式的多样性而受到巨大威胁。手机媒体内容信息网络传播权研究是著作权法学理论应用于手机媒体领域中的一项重要课题。文章以手机媒体内容的作品性为研究基点,探讨其信息网络传播权的内涵与特征,进而界定了常见的侵权行为。

Clodronate-containing liposomes attenuate lung injury in rats with severe acute pancreatitis

Objectives:Severe acute pancreatitis(SAP) can lead to acute lung injury(ALI) .The purpose of this paper is to investigate the protective effect of clodronate-containing liposomes on ALI in rats with SAP.Methods:The thin film method was used to prepare liposomes.Sprague-Dawley rats were randomly divided into three groups.After the SAP model was established by injecting 5%(w/v) sodium taurocholate(2 ml/kg body weight) into the subcapsular space of the pancreata,normal saline was administered to the control(C) group,phosphate buffer solution(PBS) -containing liposome to the Pgroup,and clodronate-containing liposome to the Tgroup through tail veins.Blood samples were obtained from the superior mesenteric vein at 2 and 6 h to measure the levels of amylase,interleukin-6(IL-6) ,and tumor necrosis factor-α(TNF-α) .Morphological changes in the pancreata and lung were observed using hematoxylin and eosin(HE) staining,while cell apoptosis was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling(TUNEL) .In addition,the macrophage marker cluster of differentiation 68(CD68) in lung tissue was detected with immunohistochemistry.Results:Blood levels of amylase,IL-6,and TNF-αwere significantly increased in the Pgroup compared to those in the Tgroup(P0.05) .In the Tgroup,large numbers of TUNEL-positive cells were observed,but no or few in the C and Pgroups.Gross inspection and HE staining of pancreata and lung showed dramatic tissue damage,including inflammation and necrosis in the Pgroup.Less remarkable changes were noted in the Tgroup,and the C group exhibited normal histology.The histological scores according to Kaiser's criteria were consistent with HE findings.The number of CD68-positive macrophages decreased in the Tgroup.Conclusions:Clodronate-containing liposomes have a protective effect against ALI in rats with SAP.Blockade of macrophages may represent a novel therapeutic strategy in SAP.     

基于超网络的知识传播趋势分析

分析知识传播趋势能够了解掌握该知识的人员个数的变化趋势,进而分辨出热点、新兴、消亡等知识.针对目前只根据专家经验定性判断知识传播趋势的不足,提出了一种利用超网络模型分析知识传播趋势的定量方法.研究中首先通过知识挖掘获取蕴含在知识载体中的知识元,然后按照数据种类的不同分别构建知识网络、人员网络和物质载体网络,利用不同网络之间存在的关系建立超网络模型.在构建的超网络中,根据知识和人员之间的关系,定量计算用来衡量知识传播广度与知识传播深度的指标,利用这两个指标的动态变化情况分析知识传播趋势.最后给出一个实例对模型和方法进行验证.
