基于技术研发与基础研究关联的中国重点技术领域前沿主题预测     

吴菲菲  李一苇  苗红 《情报杂志》2022,(1)

[研究目的]基于技术研发与基础研究的关联挖掘技术领域前沿主题,对于促进基础研究成果转化具有重要意义。但是现有技术领域前沿主题预测或者来自专利或者依据文献分析,存在基础研究与技术研发的脱节。[研究方法]以专利代表技术研发成果,通过专利的非专利引文建立技术研发与基础研究的关联关系,并提出一种综合考虑专利引用基础研究成果时滞及专利科学循环周期预测技术领域前沿主题的方法。[研究结论]研究结果显示:a.可基于技术研发成果集中引用基础研究成果的时滞区间,通过基础研究成果主题预测技术领域前沿主题;b.中国农业技术领域前沿主题包括种质资源发掘保存与创新、畜禽健康养殖与疫病防护、环保型肥料创制等;c.中国材料技术领域前沿主题包括智能材料与结构制备技术、高温超导材料与制备技术;d.中国能源技术领域前沿主题包括大规模输配电和电网安全保障、可再生能源低成本规模化开发利用、氢能及燃料电池技术等;e.中国网络信息技术领域前沿主题包括传感器网络与智能信息处理、智能感知技术、信息安全保障技术等;f.中国制造与工程技术领域前沿主题包括极端制造技术、数字化与智能化设计制造。  相似文献   

对大学英语教材进行文化素材分析的意义及方法--以《新视野大学英语读写教程》中文化素材为例     

张乐 《海外英语》2013,(8)

为了满足大学英语文化教学的需要,教师在教学过程中需对教材的文化素材进行“二次开发”,而客观有效的认识及分析文化素材是对教材进行二次开发的基础。该文从二次开发教材的角度出发,探讨对教材进行文化素材分析的意义和方法,并以《新视野大学英语读写教程》（1-4册）教材为例,对其文化素材的选材进行分析。分析结果将对进一步研究文化素材的二次开发策略有指导性作用。  相似文献   

DDC Classification Rules     

《Cataloging & classification quarterly》2013,51(2):49-70

Melvil Dewey provided generally applicable classification guidelines or rules with his classification schedules, beginning with the second edition of his scheme. Many cataloging textbooks have adopted these guidelines. Recent editions of the Dewey Decimal Classification, however, provide considerably changed, quite intricate, and edition-specific rules. The resulting two different sets of classification rules are similar in theory but very different in application. Classifiers must be aware of both sets. They are summarized in two decision charts that are intended to illustrate the differences and similarities between the two sets of rules and to encourage consistent classification decisions. The need is expressed for a parallel, end-user-oriented searching code.  相似文献   

Bibliometric Research of International Scientific Conferences Proceedings in the Context of the Current Objectives of Library and Information Service     

《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(4):103-118

ABSTRACT

The possibilities of the applications of the structure of bibliographical references in the proceedings of international scientific conferences for the management of information and library service are under discussion. On behalf of such research branches that do not have any specialized periodicals and which researchers are involved in other branches, too, it is demonstrated that the international scientific conference proceedings could be the only reliable source of references that adequately represent such branches and could be used for corresponding bibliometric studies. The results of the studies of disciplinary, chronological and species structures of references cited in the proceedings of the conferences in magnetic fluids and in bone marrow purging and processing are featured and discussed. Some results of detailed citation study of the citedness of particular authors are also presented. It is shown that the practice of taking into account the citation figures referring to only the first co-authors destroys the real picture of impact of individuals (in contrast to what Ferreiro, Ortega & Lara tried to demonstrate in 1977). The basic conclusion: there is a need in the bibliographical index of the proceedings of international scientific conferences of the citation index type.  相似文献   

Paraprofessionals at the Reference Desk

Abstract

In this article Ms. Pedzich examines a growing model of research service the use of paraprofessionals at the reference desk. She identifies the skills needed of the paraprofessinal, the designing of a training program and developing policies, procedures and manuals to assist in a successful paraprofessional program.  相似文献   

Comment on Accuracy of References in Research Quarterly for Exercise and Sport (Stull Christina,and Quinn, 1991)     

Neville D. Prendergast 《Research quarterly for exercise and sport》2013,84(3):335-336

Abstract

An adaptation of the previously developed Exercise and Self-Esteem Model (Sonstroem &; Morgan, 1989) was tested longitudinally with 93 male interscholastic swimmers from nine high schools who were evaluated at pre-, mid-, and postseason. Swimmers completed three self-perception scales that ranged from evaluations of specific swim skills (SKILL) through broader perceived physical competence (PC) to global self-esteem (SE). Performance scores (PERF) were calculated across events by standardizing swim times to a mean of 0 and a standard deviation of 1. Structural modeling analysis across the three time waves indicated an excellent data fit(χ² = 25.46, p > .15). The model was able to explain 84, 83, and 80% of PC, SKILL, and PERF, respectively, at the third testing period. Swim improvement tended to be small (median change = 2.9%). Relationships among variables at each testing period and among the same variables at different testing periods were large and as hypothesized. Several significant relationships occurred between different variables across different testing periods. These were not extinguished when social desirability was added to the model. Social desirability failed to significantly influence subsequent measures of any model variable.  相似文献

大数据环境下科技期刊同被引文献数的学术评价功能——基于与引证文献数的对比研究     

陈辉 《科技管理研究》2019,(22)

基于科技创新成果评价与管理的视角,研究科技期刊论文同被引文献数的科学内涵和学术价值。通过频数分析、回归分析与变异系数的差异性分析,对比研究引证文献数和同被引文献数的特征及评价功能。研究发现,引证文献数与同被引文献数既有正相关性,又有显著差异性,同被引文献数的内涵更为丰富。大数据环境下同被引文献数在时间上的反应速度比引证文献数快,且具有客观性、科学性和有效性等优势,具有很强的学术评价功能,涉及到期刊、论文、作者的学术影响力以及学科或选题的热度,可以作为学术评价的重要补充手段。  相似文献
