迪士尼研究院发明3D打印软质玩具

提到3D打印,人们首先会想到3D打印机将已经在电脑里定稿的形状利用多变化的塑料等硬质材质打印出来,而迪士尼公司如今希望改变这种固有的模式。迪士尼研究院（D1sney Research）日前撰写了一份名为《打印泰迪熊》（Printing Teddy Bears）的报告,     

The nature of NPD and role flexibility of R&D/marketing in a fast growing high‐tech setting

This study investigated the mutual learning process between marketing and R&D in the context of the information and communications technology industry. The relationship between product newness and role flexibility of R&D/marketing was examined via correlation analysis and multiple regression against a stratified sample of 171 new products. The results showed that different aspects of product newness are associated in a different way to role flexibility of R&D/marketing. Management should therefore be aware of such differences when planning their product development portfolio so that effective integration between R&D and marketing can be achieved.     

中专学校计算机课程的设置

中专学校培养的是应用型人才,教学目的自然也就是学以致用。对于那些相对难理解又对中专学生的就业无紧要的计算机语言类课程应当尽量少开或不开,而对于汉字录入、文档编排、表格处理、图像处理等实用性很强又利于中专学生就业的课程应加强。在课程设置上应充分考虑学生、市场、证书等因素。

Experiential learning of electronics subject matter in middle school robotics courses

The purpose of this paper is to investigate whether the experiential learning of electronics subject matter is effective in the middle school open learning of robotics. Electronics is often ignored in robotics courses. Since robotics courses are typically comprised of computer-related subjects, and mechanical and electrical engineering, these three areas should be emphasized equally. Many studies reveal impressive learning of computer science and mechanical engineering, but clear evidence of the effectiveness of electronics learning in the higher order thinking skills of middle school students is still lacking. We designed three different robotics courses with electronics subject matter introduced through experiential learning. A parallel group design was used, where three different open learning courses were implemented for middle school students. Based on results of the first and second implementations, we improved students’ learning of relevant content for each successive step of the experiment. In total, 381 middle school students participated in all experiments and were surveyed using pre- and post-tests. The collected data were analyzed using a quantitative research methodology. The findings revealed that the teaching approach was effective. During the learning process, student interest in robotics increased, and overall achievement improved with a medium effect size (η² = 0.13). The best results for the learning of electronics subject matter were found in the learning process (η² = 0.44), where experimental sharing of electronics parts was the most evident approach used by the students. Examination of learning material structure in light of the shared electronics subject matter is analyzed and discussed and possible directions for future research are presented.

浅谈中学语文教学中人文性的体现

语文教学中的人文性应体现在语文教学的全过程之中。教学目标的制定要以人为本,立足“普通的人”,教学对象中的“人”应是全面的,一个也不能少。教学内容的确定应广泛关注人文精神,必须用人文精神的眼光对语文传统进行重新理解,应该教给学生初级的审美体验,以培养学生的同情、怜悯、血性和良心。教学环节的设计要重视以情动人,只有创设了融洽的情感氛围,创造了一种使学生感到“如沐春风”一般愉悦的教学情境,才能充分调动学生的积极性和主动性。总之,以人为本的教育理念是时代发展的必然要求。

柔版印刷工艺迈进新时代

一个世纪之前，柔性版还只是一种很不起眼的，微不足道的印刷工艺，媾侯还被称为“苯胺印刷”，因为当时采用的是苯胺油墨，随新型材料的应用和印刷条件的改善，柔版印刷工艺迅速崛起，它完全废弃了苯胺油墨，由溶剂型油墨和水基油墨代替，印刷品的质量已经有了显著的改进和提高，今天的柔版印刷工艺已经是今非昔比了，它已经发成为继凸印，胶印和凹印之后又一大印刷工艺，例如在北美，目前柔版 刷在整个印刷市场中所占的份额大约在22％左右，而在包装行业中，柔版印刷已经成为了主导印刷工艺，占到了三分之二。     

Participative company management in Europe: the new role of middle management

A review of studies from different European countries reveals that research into the new role of middle management in new production systems is quite inconsistent. Referring to the example of the German 'Industriemeister' (master craftsman) it will be shown that these inconsistencies are due to different models of the future role of middle management.     

The option to expand to a next generation access network infrastructure and the role of regulation in a discrete time setting: A real options approach

Serious concerns have been raised, especially across Europe, about the role of regulation in network infrastructure investments. More specifically, the installation of optical fiber closer to customer premises, the so-called next generation access networks, requires massive investments in the face of demand and regulatory uncertainty. The purpose of this paper is to assess whether specific regulatory scenarios (permanent regulation, regulatory forbearance, regulatory holidays and sunset clauses) alter the timing of the investment decision of an incumbent to expand to a new network infrastructure exploiting the binomial lattice approach from real options analysis.
