Ines@blishing citition thresholds todetetine higMycitdp~rs, it is necesmry to control for numerous factors, including thedominance of large, high-impact journals.

BACKGROUND Functional neurosurgery is a rapidly expanding field, with an exponentially growing literature. However, as with other fields, it can sometimes be difficult to distinguish between what is incremental and what is transformational. One way of measuring durable impact is examining the number of times a specific piece of scholarship is cited by others in the field. For example, papers th...

Citation analysis does not generally take the quality of citations into account: all citations are weighted equally irrespective of source. However, a scholar may be highly cited but not highly regarded: popularity and prestige are not identical measures of esteem. In this study we define popularity as the number of times an author is cited and prestige as the number of times an author is cited...

A chronically weak area in research papers, reports, and reviews is the complete identification of important background reference documents that formed the building blocks for the research. A method for systematically determining these important references is presented. Citation-Assisted Background (CAB) is based on the assumption that important documents tend to be highly cited. Application of...

The methods presented in this paper allow for a spatial analysis revealing centers of excellence around the world using programs that are freely available. Based on Web of Science data, fieldspecific excellence can be identified in cities where highly-cited papers were published. Compared to the mapping approaches published hitherto, our approach is more analytically oriented by allowing the as...

Introduction The h-index, which was introduced by Hirsch (2005) has been criticized by Waltman and van Eck (2009, 2012) and Bouyssou and Marchant (2011) because it can lead to inconsistencies in the way in which scientists are ranked. This means that for the purpose for measuring the overall scientific impact of a scientist the h-index exhibits counterintuitive behavior. Waltman and van Eck (20...

BACKGROUND A minority of scientific journals publishes the majority of scientific papers and receives the majority of citations. The extent of concentration of the most influential articles is less well known. METHODS/PRINCIPAL FINDINGS The 100 most-cited papers in the last decade in each of 21 scientific fields were analyzed; fields were considered as ecosystems and their "species" (journal)...
