Many studies (in information science) have looked at the growth of science. In this study, we reexamine question To do (a) use current data up to publication year 2012 and (b) analyze across all disciplines also separately for natural sciences medical health sciences. Furthermore, were analyzed with an advanced statistical technique—segmented regression analysis—which can identify specific segments similar rates in history The study is based on two different sets bibliometric data: number...

Abstract Jorge Hirsch (2005a, 2005b) recently proposed the h index to quantify research output of individual scientists. The new has attracted a lot attention in scientific community. claim that single number provides good representation lifetime achievement scientist as well (supposed) simple calculation using common literature databases lead danger improper use index. We describe advantages and disadvantages summarize studies on convergent validity this also introduce corrections...

Since the 1990s, scope of research evaluations becomes broader as societal products (outputs), use (societal references), and benefits (changes in society) come into scope. Society can reap successful studies only if results are converted marketable consumable (e.g., medicaments, diagnostic tools, machines, devices) or services. A series different names have been introduced which refer to impact research: third stream activities, benefits, quality, usefulness, public values, knowledge...

Abstract In this study, we examined empirical results on the h index and its most important variants in order to determine whether developed are associated with an incremental contribution for evaluation purposes. The of a factor analysis using bibliographic data postdoctoral researchers biomedicine indicate that regarding variants, dealing two types indices load one each. One type describes productive core scientist's output gives number papers core. other impact Because evaluative purposes...

Abstract Growth of science is a prevalent issue in studies. In recent years, two new bibliographic databases have been introduced, which can be used to study growth processes from centuries back: Dimensions Digital Science and Microsoft Academic. this study, we publication data these added established (Web Clarivate Analytics Scopus Elsevier) investigate scientific the beginning modern system until today. We estimated regression models that included simultaneously counts four databases. The...

This bibliometric study of a large publication set dealing with research on climate change aims at mapping the relevant literature from perspective and presents multitude quantitative data: (1) The growth overall output as well (2) some major subfields, (3) contributing journals countries their citation impact, (4) title word analysis aiming to illustrate time evolution relative importance specific topics. is based 222,060 papers published between 1980 2014. total number shows strong...

We introduce the quantitative method named “Reference Publication Year Spectroscopy” ( RPYS ). With this one can determine historical roots of research fields and quantify their impact on current research. is based analysis frequency with which references are cited in publications a specific field terms publication years these references. The origins show up form more or less pronounced peaks mostly caused by individual that particularly frequently. In study, we use graphene solar cells to...

Abstract Research on heat waves (periods of excessively hot weather, which may be accompanied by high humidity) is a newly emerging research topic within the field climate change with relevance for whole society. In this study, we analyzed rapidly growing scientific literature dealing waves. No summarizing overview has been published hitherto. We developed suitable search query to retrieve relevant covered Web Science (WoS) as complete possible and exclude irrelevant ( n = 8,011 papers). The...

We submit newly developed citation impact indicators based not on arithmetic averages of citations but percentile ranks. Citation distributions are—as a rule—highly skewed and should be arithmetically averaged. With ranks, the score each paper is rated in terms its distribution. The ranks approach allows for formulation more abstract indicator scheme that can used to organize and/or schematize different according three degrees freedom: selection reference sets, evaluation criteria, choice...
