基于概念格的企业群体创新偏好挖掘研究

为精准捕捉各类企业创新偏好信息,提出一种专利数据驱动下基于模糊三支概念格对企业创新偏好进行群体画像的模型,以专利IPC信息为切入点层次化抽取企业群体创新偏好共性特征,实现领导型、稳定型、潜力型、危险型四类企业创新偏好的差异化多粒度刻画。在此基础上提出模糊三支概念格相似度定义,构建带有相似度的创新偏好模糊三支概念格,揭示各企业间创新偏好关联关系。以中国集成电路设计行业数据为例实证验证模型有效性,结果表明模型可以清晰展现各类企业差异化创新偏好领域布局以及结构布局,为企业竞争战略制定及政府创新决策提供理论依据及参考。     

Are gait characteristics and ground reaction forces related to energy cost of running in elite Kenyan runners?

The aim of this study was to determine whether gait cycle characteristics are associated with running economy in elite Kenyan runners. Fifteen elite Kenyan male runners completed two constant-speed running sets on a treadmill (12 km ·h^?1 and 20 km ·h^?1). VO₂ and respiratory exchange ratio values were measured to calculate steady-state oxygen and energy cost of running. Gait cycle characteristics and ground contact forces were measured at each speed. Oxygen cost of running at different velocities was 192.2 ± 14.7 ml· kg^?1· km^?1 at 12 km· h^?1 and 184.8 ± 9.9 ml· kg^?1· km^?1 at 20 km· h^?1, which corresponded to a caloric cost of running of 0.94 ± 0.07 kcal ·kg^?1·km^?1 and 0.93 ± 0.07 kcal· kg^?1· km^?1. We found no significant correlations between oxygen and energy cost of running and biomechanical variables and ground reaction forces at either 12 or 20 km· h^?1. However, ground contact times were ~10.0% shorter (very large effect) than in previously published literature in elite runners at similar speeds, alongside an 8.9% lower oxygen cost (very large effect). These results provide evidence to hypothesise that the short ground contact times may contribute to the exceptional running economy of Kenyan runners.     

我国女性体育参与的文化解读与时代特征

我国女性在体育参与中相对于男性遭遇了很多不平等的现象,这些现象必然有其文化历史根源。通过文献梳理和逻辑分析,从意识形态层面的审美取向、形成意识形态的氏族制政治生态与形成政治生态的社会及人类进化论根源三个角度,对我国女性的体育参与特征进行剥离式解读,总结出女性参与体育的时代特征。同时从经济学的视角分析了女性体育参与的机会成本或许在短时间内不会降低到与男性相同的水平,但过去阻碍女性参与体育的桎梏将随时间一一消弭。     

Made in China: the cultural logic of OEMs and the manufacture of low‐cost technology

Abstract

This paper investigates the conditions of the manufacture of low‐cost technology in China with the examples of ‘pirated’ VCD players, ‘no‐name’ DVD players, and Shenzhen’s development as a techno‐urban city. It emphasizes the significance of the cultural logic of original equipment manufacturers (OEMs) and argues that the various transformations and deflections that are derived from ubiquitous OEM experiences have gone beyond the original model of an authorized OEM, experiences that are to some extent embodied in the transgression of brand name and patent hegemonies, which are mainly controlled by high technology companies. OEMs have been associated with China’s current imperative and uninhibited development of low‐cost technology capitalism. ‘Made in China’ signifies the production of any product, legal or illegal, for transnational high technology giants or domestic technology manufacturers. Learning to ‘become an OEM’ in China has partly resulted in excessive technological mimesis that may be part of an unauthorized, underground economy that is based on low‐cost technology. Based on the Shenzhen experience, part of this study will show industrial production‐oriented OEM cultures in which illegal operations and counterfeit trade are incorporated, even in city projects that are shared by municipal governments and Chinese technological companies, and undergo spatial restructuring in the development of the economy, consumerism, and urbanism.

改革思想政治理论课教学,增强高校德育教育实效

增强德育效果是当前高校德育工作者直接面对并亟待解决的问题。思想政治理论课作为对大学生进行思想政治教育的主渠道、主阵地和基本环节,直接影响着高校德育效果的提高,是高校德育效果的基本保证。思想政治理论课教学改革,主要是通过更新教学内容、增强实践教学、改进教学方法和优化教学手段,达到增强教学效果的目的。     

高校学费依据教育培养成本收取的悖论

当前我国高校学费主要依据教育培养成本收取,但此举既缺乏理论依据,在实践操作中亦弊端百出。学费实质上是一种教育价格,学费收取的标准取决于高等教育价格的供求关系。即高等教育供给要求学费收取由政府定价为主逐步走向政府定价与学校自主定价相结合;高等教育需求要求学费价格应更多地考虑居民的经济承受能力。

The impact of workplace information literacy on organizational innovation: An empirical study

The present study investigates the relationship between CEO’s information literacy and innovation in small and medium-sized enterprises (SMEs). Even if information literacy’s business value has been recognized in recent literature, its impact on organizational innovation, a critical and strongly information intensive process, has never been studied before. Structural equation modeling based analysis of data collected from 184 company CEOs in Finland revealed that CEOs’ information literacy has a positive impact on the development of exploratory and exploitative innovations in SMEs. Additionally, opportunity recognition mediates the relationship between information literacy and innovation. Overall, the influence of information literacy is slightly stronger on exploitation than exploration. Nevertheless, the mutual positive effect suggests that information literacy enhances innovation ambidexterity in organizations. Based on these findings, we discuss theoretical and practical implications as well as future research opportunities in workplace information literacy research.
