We submit newly developed citation impact indicators based not on arithmetic averages of citations but on percentile ranks. Citation distributions are—as a rule—highly skewed and should not be arithmetically averaged. With percentile ranks, the citation of each paper is rated in terms of its percentile in the citation distribution. The percentile ranks approach allows for the formulation of a m...

This paper characterises the patterns of international medical research in Central and South America. The objective is to ascertain countries' capacity to establish intraand extra-regional scientific collaboration. The methodology used combines bibliometric techniques and social network analysis. Publication patterns are characterised by production volume, specialisation, visibility and collabo...

The Arctic fox has a circumpolar distribution and is intensively studied because it is adapted to extreme environments and influences the ecology of many other species. We introduce here a collection of 12 articles on Arctic fox biology and management. After summarizing the main biological features of the species, we explore the peer-reviewed literature dealing with the Arctic fox through a bib...

Background: Total knee arthroplasty (TKA) has brought hope to patients with malignant joint diseases. Infection is one of the serious complications after TKA, and purpose this study was use bibliometrics analyze current research status infection surgery, unmask any deficiencies research, provide references for future researchers.

Description: Understanding Large Temporal Networks and Spatial Networks Exploration, Pattern Searching, Visualization and Network Evolution Understanding Large Temporal Networks and Spatial Networks explores social mechanisms that drive network change and links them to computationally sound models of changing structure to detect patterns. The authors explore the social processes generating thes...

Capturing semantics in a computable way is desirable for many applications, such as information retrieval, document clustering or classification, etc. Embedding words or documents in a vector space is a common first-step. Different types of embedding techniques have their own characteristics which makes it difficult to choose one for an application. In this paper, we compared a few off-the-shel...

The paper presents the results of the study of international and national cooperation of Ukrainian scientists from different scientific fields using citation analysis data from Scopus in the period of 2011-2015. The results show that during the period under study, the number of documents of highly cited Ukrainian scientists that have received enough citations to be included to the top 1%, 5% an...

The importance of dimensional analysis and dimensional homogeneity in bibliometric studies is always overlooked. In this paper, we look at this issue systematically and show that most h-type indices have the dimensions of [P], where [P] is the basic dimensional unit in bibliometrics which is the unit publication or paper. The newly introduced Euclidean index, based on the Euclidean length of th...

Open-Access Mega-Journals (OAMJs) are a relatively new and increasingly important publishing phenomenon. The journal Medicine is in the unique position of having transitioned in 2014 from being a ‘traditional’ highly-selective journal to the OAMJ model. This study compares the bibliometric profile of the journal Medicine before and after its transition to the OAMJ model. Three standard modes of...
