“I thought I’d have more trouble with white people!”: Exploring racial microaggressions between West African immigrants and African Americans

Racial tensions continue in 21st-century United States through the communication of racial microaggressions. We are interested in the communication of racial microaggressions directed towards West African immigrants by people with whom they expected to be allied, African Americans. Sixteen people who identified as West African immigrants were interviewed about communication struggles with African Americans in this qualitative, interpretive analysis. Owen’s thematic analysis was employed to analyze interview data. Results suggest the communicative impact of racial microaggressions on recipients is far-reaching and consequential. Narratives illustrate microaggressive communication occurs daily through invalidating, dismissive lines of questioning as well as targeted name calling and pejorative dialogue.

课程内容研究的新视野——TIMSS课程分析工具“主题追踪图”的演进与启示

美国密歇根州立大学施密特教授等人研究开发并完善的TIMSS"主题追踪图"作为重要的整体性课程分析工具,其使用的建模方法有效弥补了传统研究方法的不足。本文通过检索"主题追踪图"的演变轨迹,认为基于该工具的国际课程比较能全面反映各国课程在主题选择与组织层面的异同,而构建的课程连贯性理想模型更是提供了一种全新的课程内容研究思路与范式。

Virtual university–a vehicle for development,cooperation and internationalisation in teaching and learning

The paper discusses the approaches of virtual university strategies and developments in Europe. The discussion is partly based on the work done in the Activity 5 in the EU Thematic Network E4 and partly to the experiences gained through the activities of EUNITE virtual university network of six European universities. Based on our experience we see, that e-learning and virtual university approach can be used for renewal of teaching and learning, both on and off campus. Just three years ago, universities seemed mainly to aim only to develop on campus teaching and learning through ICT. Lately, the use of e-learning as a tool for international cooperation and for virtual mobility (Virtual Erasmus) has started to develop through the activities of the European Union e-learning programmes and through the activities of some European university networks, like EUNITE. To promote virtual universities and e-learning, commitment and actions at all levels from EU to individual institutions are needed.

QTL analysis for some quantitative traits in bread wheat

Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits taken together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through marker aided selection.
