高职院校大学生创业园建设战略模式初探

大学生创业园建设的战略模式上存在着多种差异,产生这种差异的主要原因在于对大学生创业园建设的战略目标、形态、方针和措施等战略问题的认识不同。大学生创业园建设应以“培养创业创新人才”为战略目标;在战略形态上,以市场拉动型为主导,同时要求政府在政策上给予充分的宽松环境;在战略方针上坚持全真与仿真的结合方式;在战略措施选择上,充分考虑自由竞争与垄断保护、精英创业与大众创业、培养创业技能与培养创业素质三大关系。     

温州工业园区集群化与企业创新能力的增强

目前,温州工业园区大多是“一袋马铃薯式”的园区,未形成集群机制,创新能力有限。集群化园区内的企业既有地理邻近又有组织邻近,能产生资源集聚、分工与协作、公共物品与区域品牌共享等方面的协同效应,有利于增强创新能力。实现温州工业园区向集群化园区的转变,应强化集群意识,务实区域社会资本,构建以园区为核心的区域创新基地,并有机融入全球价值链。     

基于竞争优势模型的产业体系构建 ——以汕头华侨经济文化合作试验区为例

竞争优势理论及相关研究认为区域产业体系构建和升级已经从依靠资源禀赋结构决定的比较优势,逐渐转移到依靠禀赋结构、规模经济和技术进步构成的竞争优势。梳理了华侨试验区的竞争优势要素,从生产要素、需求条件、文化要素、产业集聚和创新能力四个方面构建华侨试验区的“钻石模型”,提出华侨试验区在近阶段应以培育壮大高级专业生产要素为目的,以直管区为核心重点发展跨境金融、商务会展、医疗旅游和信息产业的建议。以“干中学”推动华侨试验区的传统资源禀赋优势动态升级为竞争优势。     

Comparative studies on phenotypic plasticity of two herbs, Changium smyrnioides and Anthriscus sylvestris

INTRODUCTION Changium smyrnioides Wolff, a monotypicspecies of family Umbellaceae, occurs only in anarrow zone in the middle to eastern part of theChangjiang (Yangtze) River Basin, China. As ahighly valued medicinal herb, the fleshy roots ofthis species are widely picked, and as its habitatsare being disturbed increasingly by land use, it hasbecome an endangered species (Qiu and Fu, 2001).Anthriscus sylvestris (L.) Hoffm belongs to thesame family; has similar morphology and life…     

篮球多变综合防守技术的探讨

分析了篮球防守技术的发展趋势,针对现代篮球对防守技术要求越来越高,带有进攻性、破坏性的积极防守的特征,提出单一防守阵型是不够的,要把各种防守技术有机结合起来,采用综合防守技术。     

人民币汇率制度改革及政策选择

通过对现行的人民币汇率制度的缺陷进行了分析,对克鲁格曼模型进行了分层改造,并设监控指标,从而使汇率目标区重现生机.进而认为在今后很长一段时间内,汇率目标区双层监控模型将是人民币汇率制度合意的选择,汇率目标区制度的设计符合中国金融市场渐进式的开放路径,并提出人民币汇率制度改革的相应配套政策措施。     

Mathematical model of cylindrical form tolerance

Tolerance is essential for integration of CAD and CAM.Unfortunately,the meaning of tolerances in the national standard is expressed in graphical and language forms and is not adaptable for expression,processing and data transferring with computers.How to interpret its semantics is becoming a focus of relevant studies.This work based on the mathematical definition of form tolerance in ANSI Y 14.5.1 M-1994,established the mathematical model of form tolerance for cylindrical feature.First,each tolerance in the national standard was established by vector equation.Then on the foundation of tolerance's mathematical definition theory,each tolerance zone's mathematical model was established by inequality based on degrees of feature.At last the variance area of each tolerance zone is derived.This model can interpret the semantics of form tolerance exactly and completely.     

长治盆地地质构造特征及地壳稳定性刍议

长治市是山西省能源、重化工建设基地之一。建国以来工矿业发展迅速 ,随着城市建设规模的扩大 ,人口的增长和近年来环境意识的增强 ,对本区地壳稳定性的评价已成为一个人们日益关注 ,在城市建设中急待解决的研究课题。本文试图从分析和研究长治盆地及其周边地质构造特征入手对该区地壳稳定性作一初步估计     

裂纹岩体贯通机制的数值模拟研究

裂隙岩体在荷载作用下导致其内部裂纹的相互贯通,从而在裂纹尖端形成较大的塑性破坏区域,岩体工程的失稳大多是由于其内部节理、裂隙等缺陷发展导致的,应用断裂力学的方法,可以追踪岩体中节理裂隙的起裂、扩展至相互贯通使岩体局部破坏的过程,从而揭示岩体失稳的渐进破坏机制.本文采用有限元方法模拟了岩体中不同倾角的压剪裂纹的破坏问题,根据不同倾角裂纹的力学机理分析了其受力差异,依据最短塑性区距离判据分析了相近裂尖的扩展距离,得出了不同倾角的两共线裂纹相近裂尖破坏后岩桥之间的有效距离.     

Can higher-proficiency L2 learners benefit from working with lower-proficiency partners in peer feedback?

Informed by Vygotsky’s conceptualization of the Zone of Proximal Development, this case study investigated the benefits of peer feedback on second language (L2) writing for students with high L2 proficiency and the factors that may influence their learning in peer feedback in the Chinese English-as-a-foreign-language context. Specifically, the study examined whether, what, and how higher-proficiency (HP) English learners can learn when they collaborate with their lower-proficiency counterparts. Analyses of multiple sources of data – video-recordings of peer feedback sessions, interviews, stimulated recalls, and drafts of student texts – revealed that while group peer feedback in the writing classroom can provide learning opportunities for HP students, their learning can be influenced by several factors, including their beliefs about peer feedback, motives and goals for peer feedback, and medium of group discussion. Implications are drawn from these findings for peer feedback practice and research in L2 writing.
