我国高中生科学素质影响因素分析

高中生是我国科技后备人才的主力军,其科学素质直接关系到我国未来科技水平,因此探讨我国高中生科学素质的影响因素,对于提高我国科技后备人才科学素质进而提升我国科技水平具有重要意义。本文利用我国高中生大规模基线调查数据,基于教育生产函数模型,分析了我国高中生科学素质的影响因素,结果表明:竞赛因素对高中生科学素质有显著影响,班级同伴因素有较大影响,学校因素有很大影响,而家庭因素有重要影响。为此,首先,应重视不断增强科技竞赛和学科竞赛活动对高中生科学素质的提升作用,缩小班级规模、加强合作学习,从而更好地发挥班级同伴效应对于促进高中生科学素质提升的作用;其次,要引导家长形成科学的教育方式,促进高中生科学素质的提高。此外,需要加强中小学科学教育过程中对学生科学素质培养的渗透,重点关注提高西部地区和非重点校高中生科学素质问题。     

论农村社区的重建与转型

建立在集体产权基础上的现代农村,是在国家建构下的生产共同体,其治理以村民委员会自治为特征。随着农村社会流动性增加,村委会的代表性日益不足,行政干预导致村委会自治性不足,其合法性基础受到削弱。重建农村社区,形成居民自治的生活共同体,需要农村治理的转型。     

强化企业思想政治工作 促进煤矿安全生产

在煤矿安全工作中,思想政治工作通过其无形的延展力、渗透力和亲和力引导员工在增强安全防范意识,创造安全工作环境,杜绝不安全行为上起到积极的作用。思想政治工作应该围绕出发点,找准切入点,突出着力点,积极发挥优势,真正为矿井安全生产起到思想引导作用。

The school parade as a text: the management of diversity on national commemorations in Greece

The paper approaches school parades on national commemorations in Greece as a ‘text’ for storing and transmitting cultural meanings and value hierarchies. The study is based on policy documents and participant observation. The detailed Ministry instructions on how schools should select students for the parade may be viewed as instructions on how to manage dimensions of diversity. Two such dimensions are tallness and achievement, established by law as selection criteria. The latter could point to both intellectual abilities and effort. However, because of the dominance of effort in Greek educational rhetoric, achievement comes to be perceived mainly as an indicator of moral qualities, e.g. hard work. The selected students are distributed along the body of the parade according to ‘syntactic’ rules, i.e. mainly ‘firstness’. Skilful management of bodily and moral ‘diversity’ makes underlying value hierarchies explicit, thus producing cultural meanings and turning the parade into a text about the nation.     

基于供应链中不确定性的生产计划研究

供应链管理环境下的企业,将面临复杂多变的市场环境,信息的多源性、多态性和不确定性,增加了其在供应链环境下制定生产计划的复杂性和难度。论文以全球供应链为研究背景,分析了供应链环境下生产计划信息不确定性的主要根源,从不同角度分析了供应链信息不确定性对生产计划的影响,指出如何通过信息共享机制与弱化信息不确定性等提高生产计划动态响应性的方法。     

Acquiring Clinical Knowledge from an Online Video Platform: A Randomized Controlled Experiment on the Relevance of Integrating Anatomical Information and Clinical Practice

Basic subjects in medical education, such as anatomy, are often taught through teaching formats that do not always sufficiently demonstrate the relevance of this basic information for clinical practice. Accordingly, it is a recent trend in anatomy education to link anatomical information more explicitly to clinical practice. This article presents an online video platform (Tuebingen’s Sectio Chirurgica [TSC]) as one means of explicitly integrating preclinical anatomical knowledge and clinical application. The purpose of the study presented here was to examine the effects of videos through which medical students were educated about Anterior Cruciate Ligament reconstruction. A TSC video about this surgical procedure was compared to a video with a traditional lecture providing the identical information. Participants (n = 114) perceived the TSC video to be superior in comprehensibility of the presentation (P = 0.003) and conceivability of the surgical procedure (P = 0.027), and to be more entertaining (P < 0.001). Moreover, participants in the TSC condition acquired more clinical knowledge than in the lecture condition (P = 0.043) but did not differ in their acquisition of anatomical knowledge. Mediation analyses indicated that the effect on the acquisition of clinical knowledge was mediated by comprehensibility, conceivability, and entertainment. These findings are discussed regarding their implications for medical education in terms of contributing to the general trend of linking preclinical anatomical knowledge to clinical application. A discussion about the limitations of the study and suggestions for future research are also provided.     

城市生活垃圾产量的组合预测

引入一种新的预测垃圾产量的方法——组合预测方法,该法能够综合利用不同预测方法提供的信息提高预测精度。结合厦门市1996～2008年的垃圾产量,分析不同预测方法的预测精度,并预测5年后的垃圾产量。通过研究发现:单一预测模型中,线性回归法和年增长率法的预测结果偏小,误差较大,灰色理论GM(1,1)的预测结果偏大,误差较小,基本在10%以内;组合预测模型的预测精度高于单一预测模型;厦门市城市生活垃圾年平均增长率约为10%,低于国民生产总值和社会消费品零售总额年平均增长率,高于城镇居民消费性支出年平均增长率。     

网络视频在高职英语视听说教学中的应用

随着网络多媒体技术在教学上的广泛应用,高职院校相继开展了英语视听说教学。网络视频来源便利,教师可本着一定的设计原则,根据教学的实际需要,适当地使用网络视频,为学生设计不同的练习。实践证明,利用英语网络视频进行视听说教学是可行的、有效的。     

信息社会背景下的异地法官远程视频审判的设想

经济基础决定上层建筑。人类进入信息社会,作为上层建筑的司法制度也必然会进行变革。信息社会为司法的变革提供了物质基础,已经相对成熟的远程视频通讯技术使法官身处异地审判成为可能。我们设想由随机产生的不同地域的法官组成合议庭通过远程视频系统审理案件,并当庭作出判决,将法官从熟人社会中彻底解脱出来,完全不受人情、金钱和权力的影响,只凭证据和法律作出判断。但远程视频审判的实现有赖于一个比较充分的庭前准备,只有双方在庭审前充分的交流,包括证据和意见的展示,才可以使庭审顺利进行。
