石油价格波动对中国城乡居民消费水平的差异性影响研究

石油价格波动对我国城乡居民消费水平的变化有重要影响。基于计量经济模型和时变状态空间模型,采用我国2000年6月-2014年5月的时间序列数据,就石油价格波动对我国城乡居民消费水平的长短期影响效力、影响时滞和动态时变效率进行了分析。研究结果表明:在长期和短期内,石油价格波动对我国城乡居民消费水平均造成正向影响,且对城镇居民消费水平的影响效力更为显著;石油价格波动对城乡居民消费水平的平均影响时滞分别为5个月和4个月;城乡居民消费水平对石油价格变动的时变弹性起伏较大,且城镇居民消费水平对石油价格变动的时变弹性在总体上要大于农村居民消费水平对石油价格变动的时变弹性。并就上述研究结论,从调整石油定价机制、建立健全预警机制和加强对居民的政策扶持等三个方面提出了政策建议。     

A case study of integration and destreaming: Teachers and students in an Ontario secondary school respond

The direction that secondary school reform should take has become a contested question in the province of Ontario, Canada, during the 1990s. This case study of one secondary school examines some of the issues surrounding the transition years. Two policies, destreaming and integration, mandatedbythe OntarioMinistryof Education in 1993, and fully implemented by 1995, are examined by means of interview and survey. Administrators, teachers and students commented on the transition from elementary to secondary school. We discuss questions related to destreaming (especially how teachers contend with mixed-ability classes) and integration (with a particular focus on mathematics, science and technology).     

Enhancing curriculum and delivery: linking assessment to learning objectives

Typical university‐wide course evaluations do not provide instructors with sufficient information on the effectiveness of their courses. This article describes a course assessment and enhancement model where student feedback can be used to improve courses and/or programs. The model employs an assessment tool that measures student perceptions of importance and their current competence in course‐specific learning objectives both pre‐ and post‐course. Information gained from this assessment enables course improvement over time and also allows for modification in delivery and/or content of the current course. This model is intended to augment traditional course evaluation mechanisms based on specific and actionable feedback on learning objectives.     

基于地域识别的城市定位及发展模式——广东省徐闻县的实证分析

城市定位是城市发展和竞争战略的核心,发展模式是城市定位的体现和多元化的发展路径,二者通过“自构”和“被构”相互作用,推动城市发展螺旋提升,城市定位与发展模式的科学准确凸显重要。地域识别是城市定位的科学依据和逻辑起点,以其为视角分析徐闻自然地域特征与发展态势,徐闻发展现状呈现典型“十字哑铃”态势,处于发展“洼地”,应以琼州海峡为切入点和突破口,体现两岸地脉相连、文脉相近、血脉相通、经济相关、发展相促的特点。从地理学综合、系统、区域差异的视角,构建圈层扇面分析模型,科学梳理徐闻县的城市定位和发展模式。研究表明：①从国际、国家、省域和区域圈层,以及环北部湾经济圈、南海北部海洋经济区、雷州半岛和海口扇面,进行圈层扇面分析,徐闻城市战略定位可以概括为,国际海峡城市,国家生态城市,滨海生态型城市、休闲宜居城市,临港工业城市、海洋经济特色城市,港口物流城市、海峡北岸旅游城市;②产业定位应结合战略定位和资源禀赋,重点发展旅游业、蓝色经济和现代农业;③相应的主要发展模式有生态旅游与海峡联动发展模式、蓝色经济与港城互动发展模式和现代农业与休闲观光一体化发展模式三种。     

Guiding Attention Aids the Acquisition of Anticipatory Skill in Novice Soccer Goalkeepers

Purpose: The ability to anticipate the actions of opponents can be enhanced through perceptual-skill training, though there is doubt regarding the most effective form of doing so. We sought to evaluate whether perceptual-skill learning would be enhanced when supplemented with guiding visual information. Method: Twenty-eight participants without soccer-playing experience were assigned to a guided perceptual-training group (n = 9), an unguided perceptual-training group (n = 10), or a control group (n = 9). The guided perceptual-training group received half of their trials with color cueing that highlighted either the key kinematic changes in the kicker's action or the known visual search strategy of expert goalkeepers. The unguided perceptual-training group undertook an equal number of trials of practice, but all trials were without guidance. The control group undertook no training intervention. All participants completed an anticipation test immediately before and after the 7-day training intervention, as well as a 24-hr retention test. Results: The guided perceptual-training group significantly improved their response accuracy for anticipating the direction of soccer penalty kicks from preintervention to postintervention, whereas no change in performance was evident at posttest for either the unguided perceptual-training group or the control group. The superior performance of the guided perceptual-training group was preserved in the retention test and was confirmed when relative changes in response time were controlled using a covariate analysis. Conclusions: Perceptual training supplemented with guiding information provides a level of improvement in perceptual anticipatory skill that is not seen without guidance.     

区域信息化发展水平分析及对策研究——以河北省为例

随着科学技术的不断进步,信息化发展水平已成为衡量国家综合国力和国际竞争力的重要标志。区域信息化作为国家信息化的组成部分,对促进区域进步,实现区域协调发展具有重要意义。以京津冀信息化水平为研究对象,旨在了解京津冀一体化背景下,河北省信息化发展水平及现状。采用信息化发展水平评估指标体系,基于因子分析方法,选取关键性指标,对影响河北省信息化发展的关键因素进行研究,并通过对比京津冀三地指标数值,采用文献计量法定量分析河北省信息化研究热点,总结河北省信息化发展现状,发现河北省信息化进程中存在基础设施支持力度不足,科技创新能力低等问题,并提出加大基础设施投资,加速产业信息化等相应对策。

Depending on the kindness of strangers: current national data initiatives and developmental research

This article provides a brief review of current large-scale, longitudinal data collection initiatives focusing on children. These studies will be available for secondary data analyses in the twenty-first century. In addition to child outcome data, process-oriented information is being collected on child-parent interactions, quality of child care, elementary school teacher reports and classroom observations, accessibility and use of health, educational and social services, parental mental health, family violence, fathering, parental residence patterns, income and income sources, child support, employment patterns, and community characteristics. Several of these studies are randomized trials of the efficacy of early childhood intervention services and housing mobility programs. The usefulness of these efforts for exploring policy-relevant issues (child support enforcement, work requirements for welfare recipients, antipoverty strategies, housing subsidies and relocation, availability of child care, child-care subsidies) are discussed.
