采用非参数检验以及同期群分析对1978年起接受本科教育的院士群体师承效应量化测度.研究结果显示,院士群体的师承现象普遍,具有师承关系的比例达到35.62％;师承效应能够显著缩短未来当选院士进行知识积累的时间成本、做出重大创新成果的时间以及当选院士的时滞;师生关系步长每延长一代,未来当选院士的最高学位获得年龄、获奖年龄和当选院士年龄分别降低1.35岁、1.41岁和1.28岁.师从伟大导师对精英科学家的成长具有重要促进作用,师承链系统是培养精英科学家的重要途径. 相似文献

院士是我国科技领域的最高学术荣誉称号。受我国具有资源倾斜特征的科技人才政策与制度化精英主义影响,院士不仅担当了科研领军者角色,还常兼任管理职务。基于科学社会学视角的地位权力理论,当选院士会带来“马太效应”,即地位优势带来的资源积累效应。分析行政任职这一社会性权力对院士科研论文数量、影响力与贡献度的影响。采用双重差分法分析了2005—2019年320名当选中国科学院院士与同期候选但未当选的383名科学家的索引论文、管理职务等数据,结果发现：当选院士促进论文影响力、降低论文贡献度;当选院士增加了科学家行政任职的概率,进而增加了论文的影响力并降低了科学家对论文合著贡献度。最后,就我国科研机构管理与高层次科技人才政策进行了讨论。 相似文献

This study examines the extent to which politicians' visibility in traditional news coverage explains individual politicians' visibility on social media, and vice versa. We also explore whether these relationships depend on commonly identified characteristics of individual politicians. We collected data for all elected candidates from the 2012 Dutch national elections covering each 15 days prior to the election day (N = 2250). This includes 2736 newspaper articles and 77,597 mentions on Facebook and Twitter. Our results show that the traditional news agenda and social media agenda impact each other, but that the reciprocal influence is not independent of politician characteristics. 相似文献

In this paper we examine how a standardized drug distribution system contributed to a therapeutic and symbolic make-over of thalidomide. In the 1960s, thalidomide was seen as a horror drug that caused severe birth defects among over 10,000 babies who were exposed to it in utero. Currently, thalidomide is viewed as a potentially life-saving drug which is being distributed in the USA. We discuss this transformation from a social worlds perspective, showing how the standardized drug distribution system normalized the risk of foetal birth defects, while preserving the autonomy of health care professionals. The distribution system accomplished this transformation by focusing on the risk associated with female reproductive behavior, and by providing close reproductive surveillance of female patients. This standardized system solidified social inequalities and professional power relationships, revealing assumptions about trust, responsibility and risk. 相似文献

The cause of more insulin resistance in female than males are still unknown. To know the cause from early life, normal values of relevant parameters are required. So, aim of this study was to determine the reference levels of glucose and insulin in cord blood of term newborns and to examine their effects on gender, placental and birth weight of term newborns. In cross sectional study 60 consecutive term newborns were included from constituent hospitals. Placental and birth weights were measured and cord blood was collected for estimation of serum insulin and plasma glucose. Plasma glucose estimation was done by auto analyzer (GOD–POD method) and serum insulin analysis was done using Insulin ELISA Kit. After analysis, mean ± 2SD used for estimating cord blood insulin and glucose levels, which were 10.1 ± 7.8 μIU/mL and 67.8 ± 33.8 mg/dL respectively. Correlation of insulin with both birth weight and placental weight were r = 0.359 and 0.41 respectively; p < 0.001. Interestingly we found higher insulin levels in females as compared to male newborns in spite of having lower birth weight in them. In conclusion this study reported the levels of insulin and glucose in cord blood of term newborns. Incidentally, this is the first study as per our knowledge to report significant correlation between cord blood insulin, glucose with birth weight, placental weight and gender in south India. Female newborns had higher insulin levels than males, despite lesser birth weight can be attributed to intrinsic insulin resistance in them. 相似文献

目的：为了解当代女大学生自杀态度与人格特征的相关性,为女大学生自杀干预研究提供依据。方法．以安庆师范学院为例,采用分层和随机抽样相结合的方法．选取118名女大学生为被试,选取“自杀态度调查问卷（QSA）”和EPQ（中国成人量表）作为测量工具进行测查。结果,女大学生对安乐死的态度存在城乡差异,女大学生的精神质存在年级差异,对安乐死的态度与情绪稳定性等存在一定程度的相关。结论：女大学生对自杀的态度不容乐观．女大学生自杀态度与人格特征具有一定的关联．高校心理卫生工作者可在预防青少年自杀方面发挥积极的作用。 相似文献
