Integration of technical vocabulary into peer observation of teaching for Taiwanese elementary school English teachers’ professional learning

This study explored the integration of technical vocabulary into pre-observation conferences and its influence on English teachers’ professional learning and discussion in their post-observation conferences. The conceptual framework based on Harvey [2011. “A Sociocultural-Theory-Based Study of the Impact of Mediation During Post-observation Conferences on Language Teacher Learning.” Unpublished doctoral diss., University of South Florida] and Goe, Biggers, and Croft [2012. Linking Teacher Evaluation to Professional Development: Focusing on Improving Teaching and Learning. Denver, CO: National Comprehensive Center for Teacher Quality] was used to analyse the questionnaire, audio recordings, and documents collected in seven peer observations of teaching in Taiwan. This study has two major findings. First, English teachers regarded the technical vocabulary as stimuli for their professional learning; however, the range of technical vocabulary used during the post-observation conferences was limited. Second, three major factors affected their use of technical vocabulary. A new model was proposed in order to effectively integrate technical vocabulary into peer observations of teaching for elementary school English teachers’ professional learning.     

The neural bases of vitality forms

Unlike emotions, which are short-lasting events accompanied by viscero-motor responses, vitality forms are continuous internal states that modulate the motor behaviors of individuals and are devoid of the autonomic modifications that characterize real emotions. Despite the importance of vitality forms in social life, only recently have neurophysiological studies been devoted to this issue. The first part of this review describes fMRI experiments, showing that the dorso-central insula is activated during the execution, the perception and the imagination of arm actions endowed with different vitality forms as well as during the hearing and the production of speech conveying vitality forms. In the second part, we address the means by which the dorso-central insula modulates the networks for controlling action execution and how the sensory and interoceptive information is conveyed to this insular sector. Finally, we present behavioral data showing the importance of vitality forms in social interactions.     

自然资源要素综合观测指标体系探讨

为了实现自然资源的规范管理和高效利用,需要对其要素进行长期、连续、稳定的综合观测,从而获得相关的基础数据,掌握资源种类、数量、质量和资源间相互作用过程信息。由于目前中国没有形成统一的自然资源观测指标体系,导致不同区域间资源观测和管理存在差异,使得国家尺度上对自然资源的规范化管理和合理利用难以实现。因此,亟需构建一套适用于国家尺度、科学、系统、规范的自然资源要素综合观测指标体系。本文以解决认识自然生态变化规律、预判发展趋势的基础数据支撑能力不足问题为出发点,参考国内外现有观测（监测）指标体系,确立了自然资源要素综合观测指标体系建立和选取的基本原则;在自然资源要素分类的基础上,采用正、反演相结合、模块化等构建方法,建立了由36个归类模块、6个资源要素综合观测系统和若干个赋能模块构成的自然资源要素综合观测指标体系。通过建立大气-地表-地下多层次,个体-景观-区域多尺度的立体化综合观测网,获取自然资源要素数据,以期实现对自然资源的精细化管理、评价和利用。     

Review on the characterisation of ancient stringed musical instruments varnishes and implementation of an analytical strategy

For the last 60 years, varnishes of ancient musical instruments, particularly stringed instruments of the violin family dating 17th and 18th centuries, have been analysed to establish their chemical composition and multi-layered structure. The objective was to rediscover the technology for making the varnish of esteemed Italian violins and to reconstitute it. This paper reviews the physico-chemical studies published on such varnishes and also focuses on a research project carried out since 2002 at the Musée de la musique in Paris. It aims to apply in a comprehensive way different non-destructive or micro destructive methods (Py-GC/MS, IR microscopy, SEM/EDX, EDXRF, synchrotron radiation-based techniques, …) to the study of a large and representative number of ancient varnished musical instruments from a museum collection.     

基于协同表示的目标跟踪算法

提出一种基于协同表示的新的目标跟踪算法.在贝叶斯框架下,采用基于重构误差的观测似然函数和考虑遮挡的模型更新机制设计一个鲁棒的跟踪器.用l₁范数来建模重构误差以更好地容忍奇异值,同时用协同表示对编码系数进行约束.实验结果表明,和其他算法相比,本文算法能够战胜遮挡、尺度变化、光照变化、背景混乱等干扰因素,具有较高的准确度和鲁棒性.

构造辅助函数在微积分证明中的应用

微积分中中值定理的证明应用是一个难点,构造辅助函数是证题常用的手段之一,本文主要介绍构造辅助函数的三种方法：作差法、观察法和不定积分法。     

西方宪政的文化考察及其启示

中国宪政陷入困境的一个主要原因是:我们对于宪政理念的整体把握乏力,对于西方党政的历史及其意义缺乏足够了解和体悟。经过对作为范本的西方宪政进行文化的历史考察,可以认为,保障人权、限制国家权力、政治容纳性、自由、民主和法治,是西方宪政发展历程中形成的历史品格。西方宪政的历史道路给我们的启示是:宪政需要一定的社会、经济、文化条件;根植于不同文化土壤的宪政,可以具备不同的形式、价值内涵和国家政治形式;缺乏法治和权利文化资源的中国,需要寻找一个更高层次的价值,以统摄文化交融时代的宪政理论和实践。     

通过钢琴打击乐化的处理拓展钢琴音色——以巴托克《第一钢琴协奏曲》第一乐章钢琴声部为例

贝拉·巴托克是将钢琴打击乐化处理发展到顶峰的代表性作曲家,他的《第一钢琴协奏曲》的曲式结构、主题(动机)、调式调性、和声、节奏等要素,是其音乐构成的技术特点,也是他对钢琴打击乐化处理的方法,以及这种处理方法在乐曲中扮演的角色。总结演奏者如何运用更为合理的演奏方法从而更加准确地诠释作品要点,具有启发意义。
