Developing capabilities in new ventures: a knowledge management approach

On the basis of a knowledge management perspective, this paper expands the literature on new ventures’ capabilities by considering how these firms fill knowledge gaps and develop the technological, marketing, management, and ICT capabilities they need to compete. In particular, this paper investigates the role of networks in these dynamics. Although new technology-based firms have great potential to introduce innovative products into the market, they might suffer from more critical knowledge gaps and capability weaknesses than established firms. The results of a quantitative investigation of an original data set of more than 400 Italian new ventures specializing in high-tech industries show that these firms acquire knowledge to support their capability growth mainly through the management of intense relations with multiple external sources of knowledge. In addition, capability development is supported by the variety of founders’ industry experience and the presence of young graduates among the founding team.     

"泄导人情"论与"白居易现象"

"泄导人情"是白居易在《与元九书》中提出的一个重要的诗学命题。追溯白居易"泄导"理论的历史渊源,考察白居易的"泄导人情"实践即其绵延几十年的诗歌创作,分析白居易诗歌创作实践所遭遇到的深刻的现实矛盾,可以把白居易的"泄导"理论及实践在现实中遭遇到的种种矛盾统称为"白居易现象"。这一"现象"昭示着早在白居易时代,中国传统文化心理--行为模式的修补、重建已经不可避免。     

Tablets as an educational tool for enhancing preschool science

Information communication technologies (ICT) is increasingly being introduced in the preschool level, but questions have been raised regarding its potential to develop content knowledge or specific skills. This quasi-experimental study looked into the impact that hand-held tablets can have on science learning outcomes in five-year-olds. Four classes from two preschool institutions in Buenos Aires, Argentina, were selected for a six-week intervention. All four classes received training and an inquiry-based science teaching sequence, with one group from each institution also receiving tablets and specific guidance on how to incorporate them into their science lessons. Post-intervention test results showed significant improvements in science outcomes for all students, but no significant difference between the tablet-enhanced classrooms and those taught without ICT. Challenges and opportunities are discussed with regard to including tablets for teaching science at the preschool level.     

《狂人日记》多重意蕴阐释

《狂人日记》，就其显在结构和表层的社会意义而言，是一篇“暴露家族制度和礼教的弊害”的控诉书，就其隐在结构和作的主观心灵投射而言，它又是一篇忏悔和绝望之作。运用本细读和传记批评的方法，可对其复杂的意蕴作出阐释。

“中国近现代史纲要”课程的实践总结及理论思考

“中国近现代史纲要”是新形势下高校开设的一门公共必修课,该课具有历史课与政治理论课的双重特点,有利于完善高校思想政治理论课程体系,有利于改变青年大学生淡忘历史的现象,有利于培养青年学生的爱国主义观念和高尚的道德情操。经过几年的教学实践,我们体会到,要顺利实现开课目的,必须制定正确的教学原则、教学方针、教学目标、教学内容、教学方法和考核方式。     

我国农业资源法制建设问题探讨

农业资源　法是我国资源法体系的重要组成部分。当前,农业资源立法采取的是以自然资源构成要素为法律调整对象的立法模式,主要确立了权属、调查评价、规划、保护和许可审批制度,仍处于单项法律、法规为主的群法状态。法制体系不健全、内容不完善、与市场经济的经济运行机制农业资源、法律制度     

反倾销对抗博弈——兼论我国少有对外反倾销申诉的成因分析

本文首先对国际反倾销现状进行了分析,结果表明国际反倾销近３０年来愈演愈烈,尤其是对华反倾销的地位在急剧上升,究其原因是什么吗？作者建立了一个完全信息反倾销对抗博弈模型对此给予了理论解释,并经实证分析指出了在国际反倾销浪潮中我国少有对外反倾销申诉的成因,主要是专职管理投入不足、产业集中度低和不擅长反倾销博弈等,文末指出模型在许多领域具有普遍的拓展应用前景,可以类推解释许多对抗博弈问题。

Lipid peroxidation and spectrin of RBC membrane in hydroxyurea treated Eβ thalassaemia

The aim of the present work is to understand the effect of low dose of hydroxyurea (HU) therapy on oxidative damage of RBC membrane in non-transfused Eβ thalassaemia. HU was administered at a dose of 30 mg/kg/day for 90 consecutive days. The percentage of spectrin and the level of malondialdehyde (MDA), fetal hemoglobin (HbF), hemoglobin (Hb) and packed cell volume (PCV) were measured. The HbF level was significantly increased after 90 days of HU therapy. MDA level of RBC membrane was decreased. There was no change in PCV, Hb and spectrin content of RBC membrane after HU therapy for 90 days in Eβ thalassaemia. Increment of HbF in HU treated Eβ patient may have some role on the correction of oxidative damage of RBC membrane by inhibiting further degradation of spectrin and by decreasing lipid peroxidation of red cell membrane.
