认知视角下的习语可分析性与习语教学

传统习语观极大制约着习语研究和习语教学。认知语言学理论为习语的研究与理解提供了理论基础和认知框架,同时也为习语教学提供了新的视角。借助隐喻、转喻和常规知识等认知机制能够对大多数习语意义进行分析;在教学中,应关注习语并注重对习语认知分析的课堂输入和适当教学策略的配合,使学习者意识到汉、英习语在概念体系和文化内涵上的异同,从而培养和提高其准确运用习语的能力。     

基于OBE模式的“机械原理”教学改革

学生在机械设计竞赛、课程设计和毕业设计环节中出现了对机械产品开发设计过程不清楚,缺乏对机械系统进行建模、分析和优化设计的能力等问题,基于学习产出的教育模式（Outcomes- Based Education,缩写为OBE模式）对“机械原理”教学各环节进行改革。笔者提出了如下措施:从设计方法学的角度组织课程教学内容,教授过程中强调设计环节各知识点的关联性,培养学生掌握和规划机械产品开发设计过程的能力。以“机械原理”中典型机构为主,从机构运动模型构建、运动分析和优化设计三个层次设置不同项目,培养学生机构运动方案分析的能力,并在教学过程中进行了教学实践探索和持续改进。     

Positive childhood experiences predict less psychopathology and stress in pregnant women with childhood adversity: A pilot study of the benevolent childhood experiences (BCEs) scale

This pilot study examined the psychometric properties of the Benevolent Childhood Experiences (BCEs) scale, a new instrument designed to assess positive early life experiences in adults with histories of childhood maltreatment and other adversities. A counterpart to the Adverse Childhood Experiences (ACEs) questionnaire, the BCEs was developed to be multiculturally-sensitive and applicable regardless of socioeconomic position, urban-rural background, or immigration status. Higher levels of BCEs were hypothesized to predict lower levels of psychopathology and stress beyond the effects of ACES in a sample of ethnically diverse, low-income pregnant women. BCEs were also expected to show adequate internal validity across racial/ethnic groups and test-retest stability from the prenatal to the postnatal period. Participants were 101 pregnant women (M = 29.10 years, SD = 6.56, range = 18–44; 37% Latina, 22% African-American, 20% White, 21% biracial/multiracial/other; 37% foreign-born, 26% Spanish-speaking) who completed the BCEs and ACEs scales; assessments of prenatal depression and post-traumatic stress disorder (PTSD) symptoms, perceived stress, and exposure to stressful life events (SLEs) during pregnancy; and demographic information. Higher levels of BCEs predicted less PTSD symptoms and SLEs, above and beyond ACEs. The BCEs showed excellent test-retest reliability, and mean levels were comparable across racial/ethnic and Spanish-English groups of women. Person-oriented analyses also showed that higher levels of BCEs offset the effects of ACEs on prenatal stress and psychopathology. The BCEs scale indexes promising promotive factors associated with lower trauma-related symptomatology and stress exposure during pregnancy and illuminates how favorable childhood experiences may counteract long-term effects of childhood adversity.     

What factors promote student resilience on a level 1 distance learning module?

Resilience is understood to be the ability to adapt positively in the face of adversity. In relation to new students on a distance learning module, this can mean how they adapt and make sense of the demands of their chosen study to enable them to persist in their studies. This article reports a small-scale study involving semi-structured telephone interviews with students on a level 1 distance learning module at the UK Open University. Students identified the challenges they experienced such as carving out time to study alongside other commitments, as well as developing their academic writing. Students also identified factors that enabled them to adapt to these challenges and be successful in continuing to study. Students rated highly the support they received from tutors in the form of tailored, detailed feedback on their assignments. Other factors that enabled students to persist in their studies were time management, self-belief and motivation.     

社会福利视角下中文期刊数据库定价机制分析与策略建议

【目的】 基于社会福利视角,运用经济学方法解析中文期刊数据库的定价机制,并提出中文期刊数据库发展建议。【方法】 通过构建期刊数据库需求函数,比较了4种类型数据库市场对社会总福利的影响;同时采用系统动力学分析方法,研究数据库独家垄断带来的锁定效应与负面影响。【结果】 以社会总福利最大化为目标,期刊数据库作为公共品由政府投资免费提供最优,其次为开放获取与同质竞争,垄断经营带来的社会福利最小;数据库商独家垄断还会带来锁定效应。【结论】 要提升社会总福利,政府须制定适宜的产业政策,抑制期刊的“独家授权”,鼓励高校自办期刊转向开放获取,推进第三方平台整合资源,探索由政府出资建立专题期刊公共数据库。
