The last few years have seen the emergence of several open access (OA) options in scholarly communication, which can be grouped broadly into two areas referred to as gold and green roads. Several recent studies shown how large extent OA is, but there been showing impact visibility journals covering all scientific fields geographical regions. This research presents a series informative analyses providing broad overview degree proliferation data sample about 17,000 active indexed Scopus. study...

National contributions to science are influenced by a number of factors, including economic capacity, national scientific priorities, policy, and institutional settings cultures. Nations do not have equal opportunities access the global market, therefore, often seek out international partners with complementary resources expertise. This study aims at investigating collaboration strategies, focus on research leadership-measured through corresponding authorship-and its relationship impact....

This paper presents a large-scale document-level comparison of two major bibliographic data sources: Scopus and Dimensions. The focus is on the differences in their coverage documents at levels aggregation: by country institution. main goal to analyze whether Dimensions offers as good new opportunities for bibliometric analysis institutional it does global level. Differences completeness accuracy citation links are also studied. results allow profile be drawn terms its Dimensions’ more than...

Abstract This study proposes a new methodology that allows for the generation of scientograms major scientific domains, constructed on basis cocitation Institute Scientific Information categories, and pruned using PathfinderNetwork, with layout determined by algorithms spring‐embedder type (Kamada–Kawai), then corroborated structurally factor analysis. We present complete scientogram world Year 2002. It integrates natural sciences, social arts humanities. Its basic structure essential...

Abstract Domestic citation to papers from the same country and greater impact of documents involving international collaboration are two phenomena that have been extensively studied contrasted. Here, however, we show it is not so much a national bias, but on their immediate environments, an diluted as environment grows. For this reason, greatest biases observed in countries with limited production. Papers involve general, one hand, because they multiple “immediate environments,” other...

Abstract Background In the greater framework of essential functions Public Health, our focus is on a systematic, objective, external evaluation Latin American scientific output, to compare its publications in area Health with those other major geographic zones. We aim describe regional distribution output and level visibility specialization, for America; it can then be characterized compared international context. Methods The primary source information was Scopus database, using category...

This study compares the flows of mobile researchers and number publications in international collaboration within context scientific economic capacities. The goal is to identify convergence or discrepancy countries mobility determine positions relative influence both processes. Using affiliation data from publications, we analyze distributions networks their structural differences. results show that there a significant relationship between flow capacity for publishing with foreign partners...

In this study, visual representations are created in order to analyze different aspects of scientific collaboration at the international level. The main objective is identify facet research by following flow knowledge as expressed number publications, and then establishes geographical axes output, showing interrelationships domain, intensity these relations, how types reflected terms visibility. Thus, methodology has a twofold application, allowing us detect significant differences that help...

Bibliometric techniques and social network analysis are used to define the patterns of international medical research in L atin A merica C aribbean based on information available S copus database. The objective was ascertain countries' capacity establish intra‐ extraregional scientific collaboration. results show that increased output citations have heightened region's presence participation arena. These findings may be partly influenced by inclusion new journals database regional...

After discovering the promising properties of graphene, research in field is attracting large grants and sponsors with an exponential rise number papers applications. This paper presents a global map graphene its intellectual structure through terms more than 50,000 documents extracted from Scopus database 1998 to 2015. The unit analysis has been descriptors (including Authors keywords Indexed keywords) co-occurrence, using fractional counting, as measure. main lines identified are:...

The aim of this paper is to make manifest the intellectual and cognitive structure nanoscience nanotechnology (NST) by means visualization techniques. To end, we used data from Web Science (WoS), delimiting category NST during period 2000-2013, retrieving a total 198,275 documents. Through direct author citation these works, identified their origins seminal papers, through word co-occurrence extracted titles abstracts, main lines research were identified. In view both structures, may affirm...

This study explores the international profiles in collaboration and mobility of countries included so-called "travel bans" implemented by US President Trump as executive order 2017. The objective this research is to analyze exchange knowledge between relative importance specific inform evidence-based science policy. work serves a proof-of-concept utility asymmetry affinity indexes for mobility. Comparative analyses these indicators can be useful informing immigration policies motivating...
