基于LDA主题模型的学术谱系内知识传承研究——以谈家桢为核心的遗传学学术谱系为例     

刘俊婉  杨波  王菲菲  徐硕 《图书情报工作》2018,62(10):76-84

[目的/意义]学术谱系以知识传承的方式助推科学发展。研究知识传承特征,探索学术谱系传承模式及其学术产出影响效能,为探索人才成长规律及人才政策制定提供参考。[方法/过程]基于LDA主题模型,以遗传学领域谈家桢为核心的学术谱系成员发表的期刊文献为研究对象,对该谱系成员的研究主题进行抽取,借鉴生物学"遗传"与"变异"的概念,根据主题相似度将谱系成员划分为"遗传学者"变异学者"和"非遗传非变异学者",并对三种学者的学术绩效进行分析。[结果/结论]分析结果表明,谈家桢学术谱系内"遗传学者"和"变异学者"的学术绩效相对较高;"非遗传非变异学者"的数量占比最多,但学术绩效相对较低;"遗传学者"与"变异学者"在不同主题下的分布具有明显差异。  相似文献   

Investigating married adults’ communal coping with genetic health risk and perceived discrimination     

Rachel A. Smith  Alan Sillars  Ryan P. Chesnut  Xun Zhu 《Communication monographs》2018,85(2):181-202

Increased genetic testing in personalized medicine presents unique challenges for couples, including managing disease risk and potential discrimination as a couple. This study investigated couples’ conflicts and support gaps as they coped with perceived genetic discrimination. We also explored the degree to which communal coping was beneficial in reducing support gaps and ultimately stress. Dyadic analysis of married adults (N?=?266, 133 couples), in which one person had the genetic risk for serious illness, showed that perceived discrimination predicted more frequent conflicts about alpha-1 antitrypsin deficiency-related treatment, privacy boundaries, and finances, which, in turn, predicted wider gaps in emotion and esteem support, and greater stress for both spouses. Communal coping predicted lower support gaps for both partners and marginally lower stress.  相似文献

Validity of self-reported reading disability by parents of reading-disabled and control children     

Sadie N. Decker  George P. Vogler  J. C. Defries 《Reading and writing》1989,1(4):327-331

Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems.  相似文献

Cloning the Blairs: New Labour's programme for the re-socialization of working-class parents     

Sharon Gewirtz 《教育政策杂志》2013,28(4):365-378

In his speech to the Confederation of British Industry (CBI) in July 1999, the UK Secretary of State for Education, David Blunkett, set out New Labour's vision for a system of education in which there is ‘excellence for the many not just the few’. He outlined what is essentially a bi-focal strategy for achieving this vision. The first focus is on the education system itself, the structures and practices that New Labour believes need to be in place if schools and services are going to meet the needs of all children and not just a privileged minority. The second focus is on the need to promote ‘a culture of achievement’, as, according to Blunkett, the vision ‘depends on changing attitudes as well as the system itself’. This paper focuses on this second strategy, more specifically the government's attempts to change the attitudes of parents. It is argued that this strategy aims to eradicate class differences by reconstructing and transforming working-class parents into middle-class ones, that it represents possibly the most important and far-reaching aspect of New Labour's policy agenda, and that it has not so far received the attention it deserves. The paper is in two parts. The first part sets out what is involved in New Labour's programme of re-socialization and explores the mechanisms by which New Labour is attempting to universalize the values, attitudes and behaviour of a certain fraction of middle-class parents. The second part develops a critique of this programme.  相似文献
