科技人力资本视角下杰青科学家资助年龄对资助效果的影响——以杰青基金地球科学项目为例     

田人合  郑军卫  张志强  于洁  杨芳娟 《图书情报工作》2019,63(22):91-105

[目的/意义] 杰青基金实施25年来，资助者年龄呈大龄化趋势发展，深入分析该现象对完成杰青基金的影响，对未来杰青基金管理具有重要意义。[方法/过程] 研究以1994-2018年杰青基金地球科学项目为研究对象，构建科研论文产出效率、创新能力和学术影响力三个评价指标，提出"科技人力资本投入-科研产出"理论模型及假设，采用DID模型克服样本选择性偏误所导致的内生性问题，验证理论假设，实现对杰青基金资助年龄异质性的研究。[结果/结论] 实证结果表明：杰青科学家大龄化趋势日趋严重，存在明显的45岁现象；杰青基金实施20年中，支持"资助年龄越大，资助效应越好"假设的比例较低；三个评价指标维度，资助效应最大且资助年龄在39-42岁之间的年份在杰青基金实施20年中所占比例最大。因此，无论从杰青基金设立宗旨、还是从评估结果来看，都应该避免杰青科学家大龄化趋势，扩大对中低龄优秀青年人才的资助。  相似文献

The influence of childhood polyvictimization on disordered eating symptoms in emerging adulthood     

《Child abuse & neglect》2017

Children who endure multiple victimization experiences, or “polyvictims," are vulnerable to maladaptive outcomes. Yet, little research exists evaluating the relationship between childhood polyvictimization and disordered eating symptoms (DES) in emerging adulthood. The current study examines the relationship between childhood polyvictimization and DES in emerging adults. Data were collected from 288 participants across two universities using online self-report measures. Hierarchical regression analyses revealed a significant positive relationship between number of childhood victimization experiences and DES in young adulthood (ß = 0.14; p = 0.016). Female participants were more likely to demonstrate DES (ß = 0.14; p = 0.008). Further, high levels of emotion dysregulation during young adulthood were associated with more DES (ß = 0.33; p < 0.001). Findings suggest that exposure to victimization experiences in childhood increases individuals’ risk for exhibiting DES in young adulthood. Results also highlight the strong relationship between individuals’ emotion regulation abilities and the presence of DES. Findings align with the theory that children who have endured high levels of victimization often feel overwhelmed by their emotions and circumstances, demonstrate emotion regulation difficulties, and may rely on maladaptive coping strategies, including disordered eating, to manage adversities. Study results emphasize the importance of considering victimization history when working with emerging adults displaying disordered eating symptomatology.  相似文献   

Exposure to Media Violence and Young Children with and Without Disabilities: Powerful Opportunities for Family-Professional Partnerships     

Elizabeth J. Erwin  Naomi Morton 《Early Childhood Education Journal》2008,36(2):105-112

There is growing concern regarding the amount and type of violence that young children are exposed to on a daily basis. Through media, popular toys and video games violent images are consistently present in children’s lives starting at a very young age. This paper discusses (a) the growing presence of young children’s exposure to media violence, (b) the influence of media violence on early childhood development and well-being, (c) the impact of media violence on young children with disabilities, and (d) recommendations for addressing this national dilemma within the context of family-professional partnerships.

Make Me an Instrument of Your Peace: Honoring Religious Diversity and Modeling Respect for Faiths Through Children’s Literature     

Melissa Renck Peyton  Mary Renck Jalongo 《Early Childhood Education Journal》2008,35(4):301-303

Understanding and respecting young children’s religious background is an important way of respecting diversity. Due to the traditional separation of church and state, many professionals tend to ignore the significant influence of religious belief and training during the early childhood years. Sharing high-quality picture books simultaneously enables adults and peers to expand their understandings of different faiths and to communicate their respect for and interest in young children’s religious education. This editorial concludes with a selective list of picture book titles that focus on different faiths that are suitable for children in the primary grades.  相似文献

Julie Dwyer  Susan B. Neuman 《Early Childhood Education Journal》2008,35(6):489-494

The selection of books to read to young children matters enormously in the role books play for enriching children’s lives. This paper reviews the scientific evidence for the appropriate selection of books, and argues that care in selecting books targeted to children’s developing skills will enhance the power and the pleasures of reading to young children.  相似文献   

民国时期良友图书公司考略     

宋媛 《廊坊师范学院学报》2008,24(6)

《良友》画报因其独特的史学价值近年来已颇为引人注意,但关于其出版书局——民国时期上海良友图书公司的情况却有待考察。良友公司以出版画报图册、精美的文艺丛书和其他印刷业务驰名,其《良友》画报曾畅销海内外,创中国大型影写版画报之先河;所出版的以《中国新文学大系》为代表的文艺类丛书,对中国现代文学发展产生了重要影响。作为民国时期定位独特的民族企业,它的发展兴衰都是值得今日借鉴的。  相似文献   

林乐知的翻译活动与晚清政治变革的互动     

高黎平 《安庆师范学院学报(社会科学版)》2006,25(1):25-28

美国传教士林乐知的在华活动注定与中美两国的政治有着千丝万缕的联系,尤其他的西学翻译与晚清政治变革的关系更是密不可分。他的整个翻译活动绝不是一种偶然、孤立的再创作行为,而是与政治有着多层面的互动。也只有在这种互动下,他的西学译作才在客观上产生一定的现实和社会意义。  相似文献   

部分高校科技期刊青年编辑职业发展状况的性别差异研究     

刘晓涵  张铁明 《中国科技期刊研究》2016,27(8):850-856

【目的】了解高校科技期刊青年编辑在学历、职称、工作状况与态度、对收入满意度、学习情况、学术业绩等方面是否存在性别差异,并对其原因进行探讨。分别从编辑部、女性编辑自身角度提出发展建议,为进一步完善青年编辑队伍建设和提升编辑个人职业素养提供参考依据。【方法】 2015年5月至8月,采用随机问卷方式,对137名中国高校科技期刊20～40岁青年编辑人员进行了职业发展状况调查。对各统计项的频次和有效百分比进行了计算,并利用spss16.0统计软件,对男女青年编辑的学术业绩差异进行t检验,其他项目差异采用卡方检验。 【结果】 青年编辑职业发展问卷中各统计项的男女比例均有不同程度差异;男女青年编辑在近3年参加业务骨干、青年编辑培训人数、每周自学时间、人均主持编辑学课题数目方面的差异均存在统计学意义。【结论】 性别差异对青年编辑的职业发展有一定影响,但是有限;女性青年编辑不应妄自菲薄,应发挥自身先天优势,更好地为高校科技期刊发展贡献力量。  相似文献
