By modeling research systems as complex systems we generalize similarity measures used in the literature during the last two decades. We propose to use the mathematical tools developed within the spin-glasses literature to evaluate similarity within systems and between systems in a unified manner. Our measure is based on the ‘overlap’ of disciplinary profiles of a set of research systems and can readily be integrated in the framework of traditional bibliometric profile analysis. The investigation of the distribution of the overlaps provides useful insights on the dynamics of the general system, that is whether it converges toward a unique disciplinary structure or to a differentiated pattern.We illustrate the usefulness of the approach by investigating the dynamics of disciplinary profiles of European countries from 1996 to 2011. We analyze several bibliometric indicators (including publications and citations) of European countries in the 27 Scopus subject categories. We compare the disciplinary profiles of European countries (i) among them; (ii) with respect to the European standard; and (iii) to the World reference.We find that there is a convergence toward a unique European disciplinary profile of the scientific production even if large differences in the scientific profiles still remain. The investigation of the dynamics by year shows that developing countries are converging toward the European model while some developed countries are departing from it. 相似文献

Academic book and journal publishing constitutes the majority focus of university presses. Besides commercial scholarly publishers, academic scholars and researchers view the opportunities provided by university presses as important venues for the dissemination of their research. This discussion focuses on the disciplinary imperative to publish scholarship that is ever more fluid and specialized as academic disciplines continue to become further nuanced in their response to the increasing knowledge produced by humanities and social science inquiry. The focus is on university presses and not commercial scholarly presses, although constitute a significant locus of scholarly publishing. What are the general characteristics of academic specialization and university press publishing? Further, how is disciplinary fluidity, especially evolving specialization, reflected in university press book publishing nomenclature and how scholarship is tied to the intellectual preoccupations of academic specialization? Multi- and inter-disciplinarities further articulate disciplinary publishing, accelerating disciplinary fluidity. Examples from disciplinary and emerging configurations of disciplinary nomenclature utilized by university presses offers insight into specialization and publishing. Academic history publishing is used to illustrate newly emerging fluid disciplinary configurations. 相似文献

There are different ways in which the authors of a scientific publication can determine the order in which their names are listed. Sometimes author names are simply listed alphabetically. In other cases, authorship order is determined based on the contribution authors have made to a publication. Contribution-based authorship can facilitate proper credit assignment, for instance by giving most credits to the first author. In the case of alphabetical authorship, nothing can be inferred about the relative contribution made by the different authors of a publication.In this paper, we present an empirical analysis of the use of alphabetical authorship in scientific publishing. Our analysis covers all fields of science. We find that the use of alphabetical authorship is declining over time. In 2011, the authors of less than 4% of all publications intentionally chose to list their names alphabetically. The use of alphabetical authorship is most common in mathematics, economics (including finance), and high energy physics. Also, the use of alphabetical authorship is relatively more common in the case of publications with either a small or a large number of authors. 相似文献

The leaders of scientific groups appear in the last place (or in the first place) of the authors’ lists of multi-author papers more often than other scientists (group-members). The preferential position of the group leader depends on the branch of science, geographical location and the time point. New tools to study the order of authors were introduced. The validity of assessment of the contributions of particular authors to the paper solely from their ranks in the authors’ lists was challenged. 相似文献

Using an initial dataset consisting of 18.5 million distinct authors and 15 million distinct articles published in the period 2000–2016, which are classified into 29 broad scientific fields, we search for regularities at the individual level for very productive authors with citation distributions of a certain size, and for the existence of a macro-micro relationship between the skewness of a scientific field citation distribution and the characteristics of the individual citation distributions of the authors belonging to the field. Our main results are the following three. Firstly, although the skewness of individual citation distributions varies greatly within each field, their average skewness is of a similar order of magnitude in all fields. Secondly, as in the previous literature, field citation distributions are highly skewed and the degree of skewness is very similar across fields. Thirdly, the skewness of field citation distributions is essentially explained in terms of the average skewness of individual authors, as well as individuals’ differences in mean citation rates and the number of publications per author. These results have important conceptual and practical consequences: to understand the skewness of field citation distributions at any aggregate level we must simply explain the skewness of the individual citation distributions of their very productive authors. 相似文献

Language distribution in scientific communication reflects the influence of different languages on science in global perspective. The study, based on over 450 thousand scientific tweets of all publications indexed by Scopus in June 2015, reveals the language distribution in informal scientific communication. Moreover, this result is compared with the language distribution in formal scientific communication reflected in scientific publications. Results show: (1) The language of scientific tweets is concentrated in English (91%), Japanese (2.4%) and Spanish (1.7%), while the language of scientific publications is concentrated in English (90.6%), Chinese (5%) and German (1.1%). (2) Both scientific tweets and scientific publications present disciplinary differences in language distribution, reflecting the different amount of attention that authors of different languages have on certain disciplines. (3) Except Saudi Arabia, investigated countries all over the world, regardless of whether their native language is English or not, all have English scientific tweets in the dominant position. For the vast majority of these countries, the native language scientific tweets only rank the second position. (4) Overall, 26% of tweeters use more than one language to tweet scientific products, while 49% of scientific tweeters tweet everything in English only. The results indicate that English has undoubtedly become the lingua franca in informal scientific communication. 相似文献

In this paper we present a first large-scale analysis of the relationship between Mendeley readership and citation counts with particular documents’ bibliographic characteristics. A data set of 1.3 million publications from different fields published in journals covered by the Web of Science (WoS) has been analyzed. This work reveals that document types that are often excluded from citation analysis due to their lower citation values, like editorial materials, letters, news items, or meeting abstracts, are strongly covered and saved in Mendeley, suggesting that Mendeley readership can reliably inform the analysis of these document types. Findings show that collaborative papers are frequently saved in Mendeley, which is similar to what is observed for citations. The relationship between readership and the length of titles and number of pages, however, is weaker than for the same relationship observed for citations. The analysis of different disciplines also points to different patterns in the relationship between several document characteristics, readership, and citation counts. Overall, results highlight that although disciplinary differences exist, readership counts are related to similar bibliographic characteristics as those related to citation counts, reinforcing the idea that Mendeley readership and citations capture a similar concept of impact, although they cannot be considered as equivalent indicators. 相似文献

The concept of “collective” or “social” memory has assumed increasing prominence in the discourse of archivists over the past few decades. Archives are frequently characterized as crucial institutions of social memory, and many professional activities are considered forms of memory preservation. We present a systematic examination of the relationships between archives and collective memory as articulated in the English-language archival literature. We first identify the major themes regarding collective memory and categorize archival writings into four major threads. We then analyze citations extracted from 165 articles about collective memory published between 1980 and 2010 in four leading English-language archival studies journals. We identify the most influential scholars and publications and trace the evolution of the collective memory concept in that literature. By comparing the archival literature on collective memory to that indexed in Thomson’s Web of Science and in Google Scholar, we identify specific disciplines, authors, and works that archivists working on collective memory may find useful. We find that in general the archival literature on collective memory is fairly insular and self-referential and call on archivists to actively engage other disciplines when carrying out collective memory research. 相似文献

The purpose of this study was to examine whether scientific mobility, either between countries or between affiliations has an effect on researchers’ productivity and impact. In order to investigate this issue, we examined the relationships between the number of institutional affiliations and countries of the top 100 authors in seven disciplines. The selected authors’ profiles contained the number of affiliations and countries each author is assigned. We studied the number of affiliations and countries and compared them to three bibliometric indicators: the number of publications in international, peer-reviewed journals, h-index and Field Weighted Citations Impact. Our findings show that although there are differences in the relationship between mobility, productivity and impact between disciplines, mobility between at least two affiliations has an overall positive effect on both output and impact while mobility between countries does not. Therefore, in most disciplines positive impact and productivity effects are tracked in affiliation mobility within a single country. 相似文献

Scientific knowledge is constantly subject to a variety of changes due to new discoveries, alternative interpretations, and fresh perspectives. Understanding uncertainties associated with various stages of scientific inquiries is an integral part of scientists’ domain expertise and it serves as the core of their meta-knowledge of science. Despite the growing interest in areas such as computational linguistics, systematically characterizing and tracking the epistemic status of scientific claims and their evolution in scientific disciplines remains a challenge. We present a unifying framework for the study of uncertainties explicitly and implicitly conveyed in scientific publications. The framework aims to accommodate a wide range of uncertainty types, from speculations to inconsistencies and controversies. We introduce a scalable and adaptive method to recognize semantically equivalent cues of uncertainty across different fields of research and accommodate individual analysts’ unique perspectives. We demonstrate how the new method can be used to expand a small seed list of uncertainty cue words and how the validity of the expanded candidate cue words is verified. We visualize the mixture of the original and expanded uncertainty cue words to reveal the diversity of expressions of uncertainty. These cue words offer a novel resource for the study of uncertainty in scientific assertions. 相似文献

This paper presents an analysis of several dimensions of scientific performance across all research disciplines measured by seven essentially different indicators that quantify productivity (absolute and fractional), collaboration (general, per publication, and international), independence from (co)advisors, and citations. The study population consists of all researchers who have obtained a Ph.D. degree in Slovenia since the country's independence in 1991. We assign researchers to 234 disciplines based on their Ph.D. thesis’ UDC classification; for each researcher, only bibliographic data for the first 10 years of their careers were used in order to avoid inconsistencies due to different career stages.While our findings show that there are notable differences between disciplines for all indicators, we also find that the trends for individual indicators are similar for the vast majority of disciplines; specifically, we observe that the fractional productivity and independence from (co)advisors of researchers are decreasing in all disciplines throughout the observed period, whereas collaboration (general, per publication, and international), and the number of citations are increasing. Moreover, our research results expose two disciplines in terms of UDC classification (mathematics and natural sciences (UDC 5), and applied sciences, medicine, technology (UDC 6)), which stand out in terms of the analyzed indicators. 相似文献

The study investigated disciplinary differences in the use of electronic journals by academics at three state universities in Zimbabwe. The study employed a quantitative approach using a survey research design. Data were collected through structured questionnaires that were administered to a sample of 363 academics. The sample drew from all disciplines at the targeted institutions. The response rate was 58.4%. Findings showed that there were disciplinary differences in awareness, use, and possession of technological skills needed to utilise electronic journals. Academics from agriculture and environmental science, engineering, medicine, and science and technology were more aware of the resources, used them more, and possessed better technological skills than their counterparts from arts and humanities, social sciences, and commerce. The study provides important insight to university librarians regarding the policies, practices, and strategies of promoting full use of electronic journals to academics rooted in different disciplines that respond differently to the resources. 相似文献

This paper presents a methodological framework for developing scientific mobility indicators based on bibliometric data. We identify nearly 16 million individual authors from publications covered in the Web of Science for the 2008–2015 period. Based on the information provided across individuals’ publication records, we propose a general classification for analyzing scientific mobility using institutional affiliation changes. We distinguish between migrants--authors who have ruptures with their country of origin--and travelers--authors who gain additional affiliations while maintaining affiliation with their country of origin. We find that 3.7% of researchers who have published at least one paper over the period are mobile. Travelers represent 72.7% of all mobile scholars, but migrants have higher scientific impact. We apply this classification at the country level, expanding the classification to incorporate the directionality of scientists’ mobility (i.e., incoming and outgoing). We provide a brief analysis to highlight the utility of the proposed taxonomy to study scholarly mobility and discuss the implications for science policy. 相似文献

Specialist publications are an important part of professional and disciplinary development. They serve to communicate research; enable the development of a shared, contestable, and expanding knowledge base; support the educational programmes that advance the profession; grow practice; and inform the evolution of the discipline. In conservation, professional and peer-reviewed journals and other forms of publications support cultural, organisational, and scientific development; facilitate new and improved forms of conservation professional practice; enable the growth of a distinctive research-led discipline; and help conservation to more effectively compete with other disciplines for influence and funding. This paper reports on the findings of a study that investigated conservators’ opinions and experiences of peer-reviewed publishing. This study examined the value conservators place on the dissemination of their research; the obstacles to, and incentives in publishing; the views held by conservators of the benefits of publication to themselves and the field; and the impact of the field's inherent interdisciplinarity on the pattern of conservation publishing. Eighty-six conservators (conservators and conservation scientists) and ten journal editors completed an online questionnaire focusing on the communication of knowledge within the field of cultural materials conservation. Findings suggest that while the peer review process is valued, a significant number who responded indicated a preference for forms of communication other than in peer review journals or publishing in general. 相似文献
