“1234”教学模式在综合英语课程教学中的应用

在高校英语专业课程中综合英语课程在基础课程中占有显著的地位。科学的教学模式能够循序渐进地提高学生的综合能力,同时也为教学提高创造了一个良好的环境。针对“1234”教学模式在综合英语课程教学运用过程中存在的一些不足之处,提出了改进完善的措施。     

框架语义学理论在EFL阅读教学中的应用——以《致用英语综合教程》教学为例

作为理解语义学的框架语义学理论指出：对任何概念的理解必然激活其所在的框架和框架中的相关元素。它为EFL阅读教学研究提供新的途径。以《致用英语综合教程》为教学案例,演示教师在EFL阅读教学中运用框架语义理论指导学生进行阅读的教学过程。     

综合交通枢纽综合监控系统集成设计研究

作为城市综合交通枢纽中最重要的安全系统之一,综合监控系统是综合交通枢纽正常运营的前提和保证。本文基于公共安全优先理念,结合综合监控系统的构成和特点对其进行全面的功能分析,并进一步从综合决策层、监控数据共享层、监控数据接入层三个结构层面进行枢纽监控系统的结构设计,实现枢纽综合监控系统中央级系统、二级节点系统以及现场级系统之间集成。研究成果为天津站综合交通枢纽综合监控系统的设计实施提供依据。     

建构主义视野下的电子线路实验教学模式

传统电子线路实验教学模式以教师为中心,无法调动学生积极性,实验教学达不到预期效果。运用建构主义教育理论审视传统实验教学模式的弊端,从培养独立思考和创新型人才角度出发,设计适应学生实际需要,体现＂学生为中心＂的电子线路实验抛锚式教学模式是该课程改革的可行之径。     

马克思主义整体性研究综述

马克思主义理论上升为一级学科以后,马克思主义整体性研究业已成为学界的＂显学＂,不同的人基于不同的向度分别就马克思主义整体性的出场、内涵、本质、研究路径、意义等问题做了深入而全面的解析,通过系统梳理这些研究成果,不仅利于马克思主义整体性研究的深化与拓展,更有助于我们从整体上理解和把握马克思主义的本质、要义和精神实质,使其更好地发挥指导实践的功能。     

Cost effectiveness of an integrated service delivery model as measured by worker retention

This study sought to examine the impact of housing child welfare ongoing teams in the community, near client neighborhoods, and in a setting that also co-locates other service providers that serve the same clients. The focus was the impact of location and service integration on perceptions of worker stress and actual worker turnover. Thirty four workers from this type of setting and from a more traditional setting in two urban cities in a Southern state were interviewed. In addition turnover rates were calculated and compared. It was found that those located near clients and with staff from other agencies had better morale, lower stress levels, more positive attitudes toward clients and client contexts, knew more about the communities the clients lived in and had more chances to collaborate to solve client problems than those in a more traditional setting with co-location only with family support staff. The turnover rate was lower in the integrated service delivery setting than in either the traditional setting or the state overall. Thus, integration of service delivery benefits not only the child welfare workforce participants, but also the clients who have greater access to other service providers and to the bottom line of the agency through the retention of workers. Implications are described.     

Quasi-experimental evaluation using confirmatory procedures: A case study of an economic and social empowerment intervention to reduce girls’ vulnerability to HIV in rural Mozambique

PurposeOur goal was to determine whether an economic and social empowerment intervention implemented in Zambézia Province, Mozambique reduced girls’ vulnerability to HIV. We use this experience to discuss challenges of evaluating real-world interventions.MethodsTwo rounds of data were collected from 885 girls, 13–19 years, for this clustered, non-equivalent (two-stage) cohort trial. We used multi-level exact matching and difference-in-differences estimation to estimate intervention effects on two outcomes: girls’ knowledge of gender-based violence and school attendance.ResultsEstimates of two outcomes analysed indicated no statistically significant intervention effects. Preliminary analysis of data from the intervention group revealed this study was unable to obtain accurate measures for five outcomes related to HIV vulnerability.ConclusionsAlthough our study did not find evidence of impact on the a priori selected outcomes, we report on our experience implementing this robust methodologic design and describe how the challenges encountered in this program setting affected our ability to attain results. We recommend prospective evaluation designs with random allocation be accommodated early during planning. When not possible, quasi-experimental studies should collect data from large samples. To reduce measurement bias, biological endpoints such sexually transmitted infections should serve as primary outcomes for programs intending to reduce sexual behaviors.     

《综合减灾法》的立法构想

《自然灾害救助条例》在效力等级与调整内容上的缺陷与现行的大量分灾种单行法标志着《综合减灾法》的立法条件已基本成熟。该法在科学揭示减灾体系的特征、结构与功能的基础上,建立以防御、救助、重建三个系列为主干的综合性减灾法律体系,将有效调控、保障与监督我国的灾害防减工作。     

基于制度视角的企业非市场战略与市场战略的整合研究

经典的战略理论是以"市场"为核心的研究,将"非市场"概念运用到企业层次的战略与行为以寻求竞争优势是战略研究领域出现的新趋势。随着各种非市场因素对企业战略影响重要性研究的逐渐深入,非市场战略的研究逐步兴起并日益成为战略管理研究的重要内容。本文首先从制度与战略互动的新视角论述了企业的非市场和市场行为是对转型背景下非市场和市场环境特征的战略反应;然后从一个古诺竞争模型出发,通过构建博弈模型对非市场战略与市场战略的整合效应作了合理的诠释。研究发现,战略整合的核心在于两者之间的正向外溢性,主要反映在一种战略的效应会正向外溢到另外一种战略。由于市场与非市场战略的指向有所不同,有时又需要交互发生作用,因此,对二者进行有效整合,使其能量能够大于任何单一战略所不能及的限度。
