中国学生英语写作中的母语负迁移及对策

母语迁移对二语或外语学习的影响历来是语言学家们研究的重点 ,也是引起争论的焦点之一。母语迁移 ,特别是母语的负迁移涉及到二语或外语学习的方方面面 :从词汇到句法 ;从句子到篇章 ;从思维到文化 ,都将对中国学生英语写作产生影响     

The instructor self-evaluation form: Development and validation of an ipsative forced-choice measure of self-perceived faculty performance

An ipsative forced-choice college faculty self-evaluation questionnaire was developed. The instrument was validated by comparing self-evaluation scores to student rating scores and by comparing superior and nonsuperior instructors on the basis of student ratings. Both analyses yielded positive, but modest, indications of validity. Implications are discussed relative to the questionnaire's utility in faculty development activities.     

基于风险偏好的信息系统安全技术选择与配置策略研究

以IDSs和人工调查技术组合为例,通过构建博弈模型,分析了风险偏好对信息系统安全技术选择与配置的影响,认为组织风险偏好不仅影响着自身的策略也将影响对方的策略。研究结论显示风险厌恶型组织配置IDS数量并不总是高于风险中立型组织,组织风险偏好对其部署单IDS还是多IDSs甚至无直接影响。同时组织在黑客期望收益很低时对风险厌恶型黑客的人工调查率更高,而在黑客期望收益很高时其对风险中立型黑客的调查率更高。此外,黑客在组织人工调查成本较低时更倾向于入侵风险中立型组织,在人工调查成本很高时更愿意入侵风险厌恶型组织。     

The experiences of deaf and hard of hearing students at a Queensland University: 1985–2005

This article reports on the experiences of deaf and hard of hearing students at a Queensland university, which offers an extensive deaf student support program. Seventy‐two current students and graduates since the program’s inception twenty years ago completed a survey about their experiences, highlights, challenges and use of communication tools and support services at university. Findings indicate, both quantitatively and qualitatively, that students valued the specialised support services they received, although challenges in accessing the academic curriculum remained for many students. In the important area of social factors, many students reported enjoying satisfying friendships and a sense of belonging with other deaf people, often for the first time, while others experienced feelings of social isolation in a largely hearing peer group. Overall, deaf and hard of hearing students who had attended Griffith over the 20 years had a high rate of graduation, comparing favourably with other university students.     

Explorable three‐dimensional digital model of the female pelvis,pelvic contents,and perineum for anatomical education

The anatomy of the pelvis is complex, multilayered, and its three‐dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three‐dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using cryosection images obtained from the Visible Human Project, in conjunction with a general‐purpose three‐dimensional segmentation and surface‐rendering program. Anatomical areas of interest were identified and labeled on consecutive images. Each 2D slice was reassembled, forming a three‐dimensional model. The model includes the pelvic girdle, organs of the pelvic cavity, surrounding musculature, the perineum, neurovascular structures, and the peritoneum. Each structure can be controlled separately (e.g. added, subtracted, made transparent) to reveal organization and/or relationships between structures. The model can be manipulated and/or projected stereoscopically to visualize structures and relationships from different angles with excellent spatial perception. Because of its ease of use and versatility, we expect this model may provide a powerful teaching tool for learning in the classroom or in the laboratory.
