微电网的仿真与实验系统Ⅱ—建模仿真及实现

文中基于美国西部联合电网(Western Systems Coordinating Council,WSCC)3机9节点系统,建立了1个带有逆变并网接口的输电网模型,并利用逆变并网接口模型模拟了微电网与上级输电网的连接,对微电网对上级电网电压与频率的支持情况进行了数字仿真。仿真结果表明在上级输电网的有功与无功负荷发生突变时,微电网的接入使上级输电系统的有功与无功功率能够实现就地平衡,并保持系统频率与电压幅值的稳定。整个微电网系统仿真环境设定均按照实验室所能达到的低电压低容量条件下完成。文中所有仿真算法及结果均在PSCAD/EMTDC软件环境及动态模拟实验室中得到验证。     

Hope into action: How clusters of hope relate to success‐oriented behavior in school

Several studies have found that higher hope is associated with higher academic achievement. Although scholars have asserted that this association is the result of higher hope leading to an increased likelihood that students will engage success‐oriented behaviors (e.g., participating in class, completing homework assignments), very little empirical research has been done to test this assertion. In this study, cluster analyses yielded three clusters of hope (high, average, and low) in a high school sample (N = 447) and a college sample (N = 375). Differences among hope clusters were examined across three domains of indicators—engagement, disengagement, and motivational variables—associated with success‐oriented behavior in school. Results from both samples indicated that students with higher levels of hope reported higher engagement, higher motivation, and lower disengagement, with medium to large effect sizes. These results have implications for both hope research and scaling psychosocial interventions.     

Empowerment for individual agency: an analysis of international organizations’ curriculum recommendations

Much recent research stresses the increasing relevance of international organisations (IOs) for national education policymaking. Yet, IOs’ curriculum recommendations have remained largely out of scope, although they provide a forceful example of ‘soft’ governance. Based on a content analysis of 83 documents from 42 inter/-nongovernmental, global and regional organisations involved in international education networks between 1990 and 2015, this paper identifies an expansive field of IOs directing growing attention to such curricular issues as student needs, educational goals and content, as well as issues of teaching and learning. In line with much cross-national curriculum research, analysis provides evidence for the trend towards a global curriculum model stressing empowerment, individual agency and psychosocial development. The article argues that the strong focus on human capabilities and human capital in IOs’ curriculum policies reflects wider cultural transformations in contemporary world society. The article concludes by arguing for an expanded analytical scope of IOs’ educational work and a reconsideration of causal explanations in curriculum theories.

高职院校大一新生的心理问题及其调适

高职院校大一新生因环境、学习和青春期后期身心变化等而产生焦虑、抑郁、彷徨等心理问题,这会影响他们正常的学习和生活。大一新生应该改变学习观念,接受现实,改变自己,努力保持积极进取的心态,营造良好的人际关系,培养独立能力,寻求专业的心理咨询;辅导员要对学生分类区别对待,采取不同的教育方式,尤其对特殊学生群体,需要给予更多的人文关怀和心理疏导,加强与学生的沟通,引导学生运用心理调适方法调节自己,并努力营造积极团结的班集体,加强集体的凝聚力;学校应加强对新生的心理健康教育,建立系统的心理健康教育课程体系。     

互文性理论及其对同本多译现象的影响

回顾互文性理论的发展过程,分析关于互文指涉的分类方法,并从互文指涉理论的缺席前语篇的角度剖析了一本多译现象的产生原因是不同译者采用了不同前语篇链接,以及对于复调式语篇的翻译策略。     

大学生逆反心理与马克思主义理论课教学的调适对策

大学生的逆反心理不仅直接影响马克思主义理论课程的教学效果,甚至会影响到大学生的马克思主义信仰和社会主义核心价值体系建设的成败。文章通过分析大学生在马克思主义理论课程中逆反心理的表现及其产生原因,从马克思主义理论课教学的角度提出了消除其逆反心理的调适对策。     

从EGP向ESP转型中英语教师知识体系的调整与构建

ESP越来越成为高校英语教育的主体,而ESP教师培养问题也日渐紧迫。早期的教师转型的探讨带给教师更多的是压力与困惑。事实上,ESP仍然是语言类课程,外语教学知识仍然是ESP教师知识结构的主体,这既符合课程需求分析,与目前教师的总体知识体系也并不矛盾,因此ESP教师只需扩大知识面而非一味追求过于专业化的跨专业深造,这一定位也有助于教师更积极、有效地进行知识调整与构建。     

Emotional and behavior problems in adopted children – The role of early adversities and adoptive parents’ regulation and behavior

BackgroundEarly adversity and negative experiences in the adoptive family can put adopted children at risk for emotional and behavior problems.ObjectiveThis study analyzes the influence of children’s preadoptive history and adoptive parents’ characteristics on the psychosocial adjustment of nationally and internationally adopted children in Germany.Participants and settingThe survey included 172 adopted children aged between 24 and 145 months and their adoptive parents.MethodsParents provided information about preadoptive history. Information about emotional and behavior problems was obtained from the parental version of the Strengths and Difficulties Questionnaire (SDQ). Parental well-being was obtained through a composite score of three standardized measures (self-efficacy questionnaire, Perceived Stress Scale PSS-4, Brief Symptom Inventory BSI); parenting behavior was assessed with the Alabama Parenting Questionnaire (DEAPQ).Results12.5% of the adopted children scored in the clinical range of the SDQ. In a multiple regression analysis, the experience of maltreatment and neglect was the most important predictor of emotional and behavior problems at time of assessment, followed by pre- and perinatal risk and parental stress regulation difficulties, R² = .423, F(4, 128) = 28.539. Increases in the number of risk factors present were associated with a greater odd of children scoring in the clinical range of the SDQ.ConclusionsMost of the nationally and internationally adopted children in this sample were well-adjusted. Prenatal and preadoptive risk as well as stress regulation capacities of the main caregiver contributed to the child’s development. An accumulation of risks increased the likelihood of adjustment problems in adopted children.
