通过调查了解信息技术教育的现状,文章积极反思了当前中小学信息技术教师面临的问题,以专业化发展视角对新课改背景下信息技术教师的角色定位进行了认真思考,主要从信息技术教师应成为学科知识的权威、课程的建设者和开发者、学生学习的知心伙伴、教师信息素养的直接培训者等方面进行了阐述。     

Diplomats’ quality of life: The role of risk factors and coping resources

The health-related well-being of diplomats has rarely been addressed in empirical studies. This is a shortcoming since this group of expatriates is confronted with specific mobility challenges. This paper has two central objectives. First, we investigate how the self-reported health-related quality of life (HRQOL) of German Foreign Service (GFS) employees compares to respective reference values from the German general population. Second, within the framework of an expanded Job Demands–Resources (JD-R) model, we analyze how diplomats’ HRQOL is affected by exposure to international relocation mobility and various personal risk and protective factors.All employees of the GFS were surveyed using online questionnaires (N = 2433). Our HRQOL measure was derived from the “Quality of Life Questionnaire Core 30” (QLQ-C30).We show that, compared to the general population, diplomats report a worse HRQOL with respect to all subdomains included (physical symptoms as well as role, emotional, and social functioning). Absolute exposure to mobility (time spent in international rotation) did not affect HRQOL, while individually perceived stress shows significant detrimental effects and personal resources (self-efficacy, mobility-specific coping, social support) show significant beneficial effects on diplomats’ HRQOL. Perceived demands of work in diplomacy had significant health-impairment effects, but perceived resources had no additive value in explaining diplomats’ HRQOL once controlling for other factors. Moderator analyses reveal that mobility-specific coping acted as a buffer in the relationship between perceived stress and perceived job demands and HRQOL.Practical implications are drawn as to support plans that respect the individual’s stress perceptions and available resources.     

“孟母教子”故事考论

孟母教子的故事在我国历史上流传很广,我们不必把它们全部据为信史。从故事产生时代看,当时正值西汉前期儒家学派地位上升、国家为加强封建统治大力推行罢黜百家、独尊儒术之际,因此它所反映的时代内涵远比故事内容本身的真实性重要。同时,这些故事本身也表明:至迟在西汉初期,人们已经认识到家庭教育在子女成长过程中发挥的重要作用,故事中提到的某些教育思想至今仍有现实意义。

城乡融合视域下易地扶贫搬迁移民社区教育发展探究

做好易地扶贫搬迁后续帮扶工作是巩固拓展脱贫攻坚成果的重要举措。社区教育作为有效帮扶途径之一,不但有助于乡村振兴战略的落实、脱贫长效机制的建立、搬迁地区终身教育体系的构建,更有助于搬迁移民尽快适应新社区的生产生活方式,实现在搬迁后"稳得住、能致富"。国家与地方出台的相关文件、我国历史上的社区教育经验以及移民自身的学习需求,为开展易地扶贫搬迁移民社区教育提供了政策基础、实践基础和动力基础。易地扶贫搬迁移民社区兼具城镇与农村特征,故需从城乡融合视角制定其社区教育发展路径:一是以"稳秩序升内涵"为宗旨,确立社区教育的发展定位与目标;二是以"广服务融生活"为目标,构建社区教育的内容与载体;三是以"多形式活方法"为理念,组织与实施社区教育活动;四是以"成合力升效率"为指向,保障社区教育的运行与效率。总之,开展易地扶贫搬迁移民社区教育应当基于城乡融合发展理念,注重将其与产业发展和社区治理相结合。     

共享单车搬迁策略研究

为满足单车用户的用车需求,对共享单车搬迁策略进行研究,提出两阶段共享单车搬迁策略。离线阶段构建单车停放区域提取模型,采用改进的DBSCAN聚类方法（District Pick up Technology, DPT）获取各时段热门用车区域、用车频率与行程结束后的放车区域、放车频率;在线阶段提出搬迁优化模型（Relocation Optimization Plan,OMP）,根据当前时段的用车区域,搜索距离其最近的前一时段K近邻放车区域,并结合实时路况为其推荐前K条路况良好的单车搬迁路径。相较于传统的共享单车搬迁策略,在拥堵比例为48%时,OBJ值至少缩小52.4%,AT值至少缩小52.6%。
