基于专利引用跨越度计量的两国间间接创新合作机会发现

[目的/意义] 两个国家间的创新合作机会有些是显性直接的，有些是潜在间接的。在此试图构建一种计量和分析专利引用关系的方法，用于发现两国间潜在的间接创新合作机会。[方法/过程] 全球价值链上不同环节专利之间的引用关系中，蕴含着相互衔接、配套的间接合作关系，而不同环节的专利通常具有不同的功能，即IPC存在一定跨越度。因此，设计"专利引用跨越度"指标及算法，用于计量和筛选专利引用网络中"引用跨越度"达到预设阈值的专利引用关系，作为发现间接创新合作机会的基础数据。以新加坡在中国获得授权的发明专利为样本，基于专利引用跨越度计量并配合人工解读和识别，发现中新两国间一系列的间接创新合作机会。[结果/结论] 基于专利引用跨越度计量的两国间间接创新合作机会发现的方法，被实验检验为有效。     

Performative technologies and teacher subjectivities: A conceptual framework

Critical educational literature suggests that an increased reliance upon performative technologies is currently transforming the very foundations from which teacher subjectivities are constructed. Arguably though, the number of studies pointing to this risk or tendency is considerably larger than the ones theorising why this should be the case. Further, in those cases where the relationship between performative technologies and teacher subjectivities is theorised, the psychological mechanisms that the technologies appeal to are seldom brought to the fore. Based on this, the purpose of this article is to theorise the psychological mechanisms that performative technologies appeal to and work through, by means of identifying, systematising and elaborating extant understandings of such mechanisms in the critical educational literature. The results are presented in the form of a conceptual framework (referred to as the CMIS-framework) which suggests that one and the same performative technology may play many different roles, where each such role appeals to and works through a particular psychological mechanism. Importantly, depending on the type of psychological mechanism that is appealed to, the CMIS-framework suggests that this will lead to teachers (un)consciously conducting particular forms of subjectivising work upon themselves, here referred to as compliance, mirroring, identification and self-realisation (CMIS).     

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.

Medieval and renaissance glass technology in Valdelsa (Florence). Part 1: raw materials, sands and non-vitreous finds

A significant number of archaeological finds of the 13th–16th century from the Tuscan sites of Germagnana and Gambassi in Valdelsa—FI, was studied by different physico-chemical investigations (SEM–EDS, ICP, Mössbauer spectroscopy, XRD, XRF, TG-DTA) in order to contribute to clarify the production methodology and the pre-industrial glass manufacture technology. The studied samples are mainly non-vitreous finds as production waste, refractory materials, crucibles and raw materials; also vitreous finds as frits, skims, glasses (glass masses, glass working waste and finished products) have been taken into consideration. The obtained petrographic and physico-chemical data strongly suggest that both Gambassi and Germagnana glass manufactures were strictly connected with the sources of vitrifiable materials, situated in Tuscan sand quarries. In particular a comparison between sands from the neighbouring quarries and appropriate finds of the two archaeological sites evidences that the employed vitrifiable materials possibly belong to La Casina La Cava resort. The archaeological classification, based on macroscopic observation and stratigraphic position, was compared and verified with the scientific classification of the examined finds of Germagnana and Gambassi sites based on their composition, morphology and physico-chemical properties.     

对篮球防守中手臂动作运用的探讨

篮球防守的技术动作由脚步移动和手臂动作共同构成,手臂动作在防守中起着十分重要的作用,是提高防守质量不容忽视的环节。为了提高防守的攻击性,必须重视对防守时手臂技术的掌握和运用,同时在比赛中也必须避免盲目、随意用手的习惯。本文分析了几种防守状态下的手臂运用技术,以期为训练和比赛提供一些有意义的参考。

关于中国男篮在世界大赛中成绩滑坡的原因剖析

采用文献资料与理论分析等方法 ,对中国男篮在第 2 7届奥运会和第 14届男篮世锦赛上攻、防技术资料进行分析研究 ,发现中国男篮整体实力确有提高 ,尤其是内线实力明显增强。但由于我国对篮球本质认识上的偏差 ,过分追求队员高度而忽视速度、战术与技术训练 ,特别是外线控球能力的培养 ,结果比赛时内、外线脱节 ,整体攻、防节奏慢 ,不仅内线实力难以发挥 ,相反丢失了过去快速、灵活的优势与特点。针对存在的问题 ,从主观认识、训练方法以及训练内容等方面提出了一些建议和改进措施。
