Emerging research topic detection can benefit the research foundations and policy-makers. With the long-term and recent interest in detecting emerging research topics, various approaches are proposed in the literature. Though, there is still a lack of well-established linkages between the clear conceptual definition of emerging research topics and the proposed indicators for operationalization. This work follows the definition by Wang (2018), and several machine learning models are together used to detect and foresight the emerging research topics. Finally, experimental results on gene editing dataset discover three emerging research topics, which make clear that it is feasible to identify emerging research topics with our framework. 相似文献

Various studies have been devoted to the evaluation of the research and development (R&D) performances of universities and research institutes. However, existing studies tend to focus on static systems, that is, systems with no intertemporal effect. To tackle this issue, this study attempts to assess relative R&D efficiency of institutes from a dynamic perspective. The unified two-stage model proposed by Kao (2017) made a contribution to combining division efficiencies in the multiplier form with frontier projections in the envelopment form in a unified framework. We develop his model in a dynamic framework into which the effects of carry-over activities are embedded across the period. If the dynamic effects in the efficiency measures are not considered, the results will be biased. This is one of the few studies to examine dynamic effects within the framework of the R&D process. Our analysis is based on samples of 17 research institutes in the Chinese Academy of Sciences over the period of 2012–2015. When compared with the proposed data envelope analysis (DEA) model, results show that the static DEA model may underestimate the R&D efficiency scores. The institutes experienced significant improvements in system efficiency, mainly due to the improvements in transfer efficiency. However, there is still much room for improvement in transferring scientific and technological (S&T) achievements. We also find that the resource scale played an important role in influencing basic research. Finally, the projections of inefficient institutes indicate that most institutes had insufficient carry-over inputs (newly approved projects and management cost) based on the average four-year values, and existing slack resources for managers to improve the future performance. 相似文献

[目的/意义]引用语境是科学论文中包含引用的句子,是对引文的描述性或评价性文字。通过提取和分析引用语境中的线索词,可以了解引用语境的一般特征。[方法/过程]以Journal of Informetrics（JOI）期刊为例,选取人称代词、行为动词和连接词三类常用的线索词,分别计算它们在引用语境中的频次、占比和排序。通过比较各类线索词在引用语境和非引用语境中的存在度,识别引用语境中的常用句型和论证模式。[结果/结论]在JOI期刊中,引用语境主要表现出如下特点：侧重于第一人称和第三人称论述,既展现他人的工作,也展现作者的研究;偏重于研究方法类引用,常用的行为动词为"use"base"和"study";强调通过转折和列举等逻辑方式进行论证,最常用的连接词位"also"和"but"。分析引用语境中的线索词,对于更好地理解科学论文中的引用的功能和动机具有重要的价值和意义。 相似文献

The purpose of the Kazakh publication citation indicator that has been developed in Kazakhstan since 2005 is to carry out
scientometric analysis of scientific publications to determine their citation rate. At present, the bibliographic database
(BDB) on citation includes information on the publication activities and citation index of approximately 30000 Kazakh scientists
and specialists. They had over 18000 scientific papers published in over 500 domestic and foreign journals. The total quantity
of references to papers by Kazakh scientists was more than 28000. The Kazakh analogue of the science citation index determination
system is an efficient tool for analytical work with the BDB of scientific publications, which makes it possible to calculate
publication activities and citation parameters, which are used to define the value and demand for the results of scientific
work in various fields of domestic science. 相似文献

Modeling a century of citation distributions 总被引：1，自引：1，他引：0
The prevalence of uncited papers or of highly cited papers, with respect to the bulk of publications, provides important clues as to the dynamics of scientific research. Using 25 million papers and 600 million references from the Web of Science over the 1900–2006 period, this paper proposes a simple model based on a random selection process to explain the “uncitedness” phenomenon and its decline over the years. We show that the proportion of cited papers is a function of (1) the number of articles available (the competing papers), (2) the number of citing papers and (3) the number of references they contain. Using uncitedness as a departure point, we demonstrate the utility of the stretched-exponential function and a form of the Tsallis q-exponential function to fit complete citation distributions over the 20th century. As opposed to simple power-law fits, for instance, both these approaches are shown to be empirically well-grounded and robust enough to better understand citation dynamics at the aggregate level. On the basis of these models, we provide quantitative evidence and provisional explanations for an important shift in citation practices around 1960. We also propose a revision of the “citation classic” category as a set of articles which is clearly distinguishable from the rest of the field. 相似文献

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

Snickers’ “you’re not you when you’re hungry” (YNY) campaign premiered in 2010. Ad agency BBDO, New York (2017) designed the ads as the centerpiece of an expensive, celebrity-filled Super Bowl promotion. This rhetorical analysis interprets the ads in terms of celebrities serving as intertextual messages that not only sell nut-filled chocolate bars but also reinforce identity stereotypes. In particular, the ads reinforce stereotypes of traditional sex roles. The ads reward viewer knowledge that plays into these stereotypes. 相似文献

Courses: Storytelling, persuasion, gender and communication, argumentation and debate.Objectives: In this essay, I map a unit-specific activity for an undergraduate class in argumentation and debate. I argue for the integration of a trans-affirming pedagogy as a key rhetorical frame in communication studies courses. Such pedagogical commitments push instructors to integrate a critical communication methodology while challenging structures that continue mitigating trans experiences, embedding critical interrogation of systemic injustice. Borrowing from LeMaster (Discontents of being and becoming fabulous on: Queer criticism in neoliberal times. Women’s Studies in Communication 2015;32:167–186. DOI: 10.1080/07491409.2014.988776), I use trans heuristically, whereby “trans and transgender are not necessarily intended exclusively as identities?… In this way, trans and transgender have two functions: as heuristics and as identities” (p. 169). Thus, as a pedagogical approach, a trans sensibility extends instruction methods to consider, criticize, and analyze binaries of thought, mundane performances of identity, and unlikely communicative phenomena that “get at gender in unsuspecting ways” (LeMaster, B., & Mapes, M. Transing priestly performances: Re-reading gender potentiality in Erdrich’s the last report on the miracles at little no horse. In S. Howard (Ed.), Critical articulations of race, gender, and sexual orientation. Lanham, MD: Lexington, 2014, pp. 161–177). Using an activity from the unit “Argumentation with and as Narrative,” I draw on Enke (Enke responds to Nakamura. In V. Muñoz & E. K. Garrison (Eds), Transpedagogies: A roundtable discussion. Women’s Studies Quarterly 2008;36:288–308. DOI: 10.1353/wsq.0.0093) to ask, “How do we engage with the privileged spaces we occupy as trans and nontrans educators as a way to build alliances that are liberatory rather than oppressive to one another?” (p. 303). 相似文献
