Understanding L2 French teaching strategies in a non-target language classroom context

This research explored the congruence and disparity between teachers’ and students’ attitudes towards French as a second language (L2) teaching strategies in a non-target language classroom context in the USA. The findings suggest students’ and teachers’ attitudes towards the direct and indirect teaching strategies were generally consistent, but not in terms of the collaborative teaching strategies. The findings also indicate that the beginner and elementary level students held different preferences for all the three teaching strategies. The underlying reasons could be learners’ different language proficiency levels, and how well teachers execute these different teaching strategies in class. This study concludes with some implications for foreign language teacher education.     

The technology transfer of the ICT curriculum in Taiwan

Focusing on the process of “technology transfer”, this paper aims to critically examine the production and usage of the information and communication technology (ICT) curriculum, and discusses its possibilities. It is found that the goals in both of the two stages of the ICT curriculum in Taiwan were rather “rhetorical”. Three problems are then discussed: an “inevitable” discourse, but opposed to its original intention, the exclusion of instructional issues, and the exclusion of students' life experience and reflection. Finally, three possibilities for the ICT curriculum are proposed: expanding educators' understanding of the ICT curriculum, developing an ICT curriculum beyond the dominance of ICT experts, and rethinking the role of teachers in the implementation of the curriculum.

Formation of lipid bilayer membrane in a poly(dimethylsiloxane) microchip integrated with a stacked polycarbonate membrane support and an on-site nanoinjector

This paper describes a new and facile approach for the formation of pore-spanning bilayer lipid membranes (BLMs) within a poly(dimethylsiloxane) (PDMS) microfluidic device. Commercially, readily available polycarbonate (PC) membranes are employed for the support of BLMs. PC sheets with 5 μm, 2 μm, and 0.4 μm pore diameters, respectively, are thermally bonded into a multilayer-stack, reducing the pore density of 0.4 μm-pore PC by a factor of 200. The BLMs on this support are considerably stable (a mean lifetime: 17 h). This multilayer-stack PC (MSPC) membrane is integrated into the PDMS chip by an epoxy bonding method developed to secure durable bonding under the use of organic solvents. The microchip has a special channel for guiding a micropipette in the proximity of the MSPC support. With this on-site injection technique, tens to hundreds of nanoliters of solutions can be directly dispensed to the support. Incorporating gramicidin ion channels into BLMs on the MSPC support has confirmed the formation of single BLMs, which is based on the observation from current signals of 20 pS conductance that is typical to single channel opening. Based on the bilayer capacitance (1.4 pF), about 15% of through pores across the MSPC membrane are estimated to be covered with BLMs.     

中国北方农牧交错带草本植物δ15N梯度变化及其对环境信息的指示

植物氮同位素组成（δ¹⁵N）是气候环境变化和生态系统氮循环的综合结果,开展典型区域植物δ¹⁵N的研究可以指示气候环境的变化。沿400mm等降水量线测定中国北方农牧交错带草本植物和土壤的δ¹⁵N值,并将δ¹⁵N值与气候环境因子进行统计分析。结果表明：1）样带草本植物δ¹⁵N值分布在-5.5‰~15.3‰之间（平均值4.02‰）,其中,C3草本植物的δ¹⁵N值范围（-5.5‰~15.0‰）比C4植物（-2.85‰~15.3‰）宽,但平均值显著低于C4植物;土壤δ¹⁵N值范围为1.42‰~9.11‰,平均值为4.74‰;2） C3、C4草本植物整体以及2种广适性草本植物的δ¹⁵N值与经纬度均呈显著正相关性（C4草本植物δ¹⁵N值与经度关系不显著除外）,但与海拔关系微弱;3）植物/土壤的δ¹⁵N值均随温度升高呈显著偏负趋势,其中C3、C4草本植物的温度系数分别为-0.41‰/℃和-0.39‰/℃,但植物δ¹⁵N值随降水增加呈微弱偏负趋势;4）偏相关分析显示,在控制降水变化后,草本植物δ¹⁵N值与年平均温度的相关性更加显著,而在控制温度变化后,植物δ¹⁵N值与年平均降水量的关系更加微弱。研究表明在水分变化相对较小的条件下,温度可能是控制本样带植物δ¹⁵N值变化的关键因子,意味着植物δ¹⁵N信息可以指示中国北方农牧交错带温度的变化。     

Method for the quantitative evaluation of universities’ publishing activity by countries based on the Taiwanese ranking

Method for the evaluation of universities’ publishing activity by countries in different fields of knowledge with identification of leading clusters of countries are suggested on the basis of the Taiwanese ranking of the leading universities of the world. It is reasonable to include such calculations into the calculation system of the annual global Taiwanese ranking.
