The mediator effects of conceiving imagination on academic performance of design students

Three studies were combined to examine the effects of creativity and imagination on the academic performance of design students. Study 1 conducted an exploratory factor analysis to determine the most appropriate structure of the Creativity Capability Scale (CCS) in a sample of 313 college students. The scale was a new self-report measure, and it was developed to be both empirically valid and easy to administer. A two-factor solution identified originality and useful flexibility as dimensions of human creativity. Study 2 conducted a confirmatory factor analysis to confirm the established structure of the CCS in a sample of 284 college students in design schools. In addition, we also confirmed the structure of the Imaginative Capability Scale using the same sample. A three-factor solution supported an earlier study in which human imagination was categorized into three types, namely initiating, conceiving, and transforming imaginations. The analyses of composite reliability and construct validity gave both scales good support. Study 3 further tested the effects of creativity and imagination on academic performance in a sample of 271 design students. The hypothesis of Study 3—that conceiving imagination acted as a mediator between creativity/imagination and academic performance—was partially supported. The structural model also showed that useful flexibility, initiating imagination and transforming imagination demonstrated positive, indirect effects on academic performance. Critical reflections on the results are provided. Discussions for future studies are also proposed.     

Entrepreneurial firms’ network competence,technological capability,and new product development performance

Successfully developing new products is critical to an entrepreneurial firm’s continued success. Based on the resource management model, this study aims to answer the key research question: how entrepreneurial firms leverage network competence and technological capability to enhance their new product development (NPD) performance in a turbulent environment. Using data collected from 134 entrepreneurial firms in China, we investigate the performance effects of network competence and technological capability, and the moderating effects of technological turbulence and market turbulence. Our findings show that network competence has a positive impact on NPD performance and technological capability plays a mediating role between network competence and NPD performance. Technological turbulence enhances the performance effects of network competence and technological capability; market turbulence advances the performance effect of network competence, but fails to exert significant negative impact on that of technological capability. We discuss managerial implications of our findings and offer directions for future research.     

我国民营企业转型升级的政府作用研究——基于政府行为视角的实证分析

将政府行为细化为政府效能、监管质量、法律规则和腐败控制四个变量,并对民营企业转型升级的相关指标进行量化处理,建立了衡量我国民营企业转型升级的综合指标,对政府行为对民营企业转型升级的影响进行了量化分析,得出以下结论：政府效能、监管质量和法律规则是影响民营企业转型升级的重要影响因素;政府效能与民营企业转型升级呈现正相关关系,政府效能越高,越有利于民营企业转型升级;监管质量对民营企业转型升级的影响较为显著,监管质量越高,越有助于民营企业转型升级;法律法规对于民营企业转型升级具有重要的影响作用,法律法规的执行力度越大,越有利于民营企业的转型升级;腐败控制与民营企业转型升级尽管也呈现一定的正相关关系,但并不很显著,这表明腐败控制的效果并没有直接反映为促进民营企业转型升级的重要因素.     

科技型中小企业成长因素分析

对我国科技型中小企业成长的影响因素进行的理论和实证分析表明,受制于现阶段我国科技进步的国情,作为我国科技创新主体的广大科技型中小企业的发展状况并不是很乐观。大部分科技型中小企业仍然处于传统产品的生产领域中,企业科技投入水平低,限制了企业的进一步成长。对科技人员和知识成果不够重视,仍然以传统的方式进行生产经营,企业未来的成长性因此受到很大限制。     

桑叶配方颗粒物质基准研究

桑叶配方颗粒迄今尚没有统一的质量标准。为提升桑叶配方颗粒的内在质量,对其物质基准评价方法进行了研究。选取具有代表性产地的15批桑叶制备物质基准,采用高效液相色谱法,以芦丁、异槲皮苷、紫云英苷作为评价指标,确定桑叶物质基准的出膏率范围、标志性成分含量及转移率范围,采用超高效液相色谱法,建立物质基准UPLC特征图谱,并对其主要成分进行指认。结果表明:15批物质基准中,芦丁转移率为19.94%～34.05%,异槲皮苷转移率为11.67%～43.58%,紫云英苷转移率为10.73%～43.05%;物质基准特征图谱中,标定了14个共有峰,指认出7个色谱峰,分别为新绿原酸、绿原酸、咖啡酸、芦丁、异槲皮苷、槲皮素-3-O-(6″-O-丙二酰基)-β-D-葡萄糖苷、紫云英苷。所建立的基准评价方法为桑叶配方颗粒质量标准的制定及其后续大规模生产提供了数据基础。     

创新团队公平感知与知识共享行为关系研究——以成员信任为中介变量

创新团队组织形式的蓬勃发展使得团队成员的绩效激励方式成为众多管理者的研究课题。团队中掌握独特隐性知识的成员往往不愿意共享自身的有利于团队的创新知识,从而给团队的发展带来困难。如何针对这类员工做出有利于团队整体绩效提升的激励活动,是创新团队管理者和所有创新团队工作模式研究者的共同目标。通过数据模型的回归,得出如下结论:创新团队的成员公平感知与成员知识共享行为正向相关,成员对互动公平的感知对知识共享行为的影响最为显著。验证了创新团队成员信任在成员公平感知与知识共享行为之间的中介效用。     

美国海域油气区块租赁规划和管理及其对中国的启示

美国海域油气管理部门主要为海洋能源管理局和安全与环境执法局。海域油气租赁区块来自联邦政府所属的近海外大陆架,对外租赁的每个油气区块都必须包含在5年规划内。美国政府制定海域油气区块租赁5年规划会结合国家安全和资源情况,总统有撤回计划的权利,政府也可根据油气市场等因素予以变更。官方网站按月发布有效租约面积、矿业权人及区块是否在产等信息进行区块合同管理。美国勘探租约期限最长为10年,可申请多次延续。通过分析中美两国油气区块管理制度等社会环境,针对中国目前尚未制定专门的油气出让规划的现状,建议逐步建立中国油气区块出让规划,明确规划权威性,保障规划实施;高度重视规划编制的前期调查与研究,建立与中国资源品质配套的出让规划;加大中国油气上游行业投资环境研究,吸引潜在投资群体。
