Growth in the number of references in engineering journal papers during the 1972–2013 period

The number of references per paper, perhaps the best single index of a journal’s scholarliness, has been studied in different disciplines and periods. In this paper we present a four decade study of eight engineering journals. A data set of over 70,000 references was generated after automatic data gathering and manual inspection for errors. Results show a significant increase in the number of references per paper, the average rises from 8 in 1972 to 25 in 2013. This growth presents an acceleration around the year 2000, consistent with a much easier access to search engines and documents produced by the generalization of the Internet.     

The production of science in Africa: an analysis of publications in the science disciplines, 2000–2015

The importance of science in Africa has been gaining the interest of scholars and policymakers alike who find that the relationship between science and development is getting stronger than ever. Science in Africa continues to find its own place in the global world of science. However, there have not been any attempts in recent years to study the production of science in all African countries taken as a whole. In this bibliometric study, science in Africa is analyzed using the publications African countries have produced in the last 15 years i.e. from 2000 to 2015. It is not only the number of publications but also the research areas which are of great importance. Not many recent studies have examined the publication productivity of all African countries. The analysis undertaken here shows that a few countries, namely, South Africa, Egypt, Tunisia, Nigeria and Algeria are the leading countries. These produced the highest number of publications during 2000–2015. At the same time, some of the weakest countries in Africa have strengths in specific research areas and are thus able to contribute to knowledge production in those areas. The findings presented in the paper suggest the implications for development in Africa and the measures which could be taken.     

Fractions of fatal crashes attributable to speeding: Evolution for the period 2001–2010 in France

Road safety is a major concern in the West, especially in France. Among all the established risk factors for fatal crashes, speed is specific in two ways: every road-user is exposed to it, and it increases not only crash rates but also the severity of crashes. Thus, speed regulation is of primary importance in road-safety policy and has also generated much public debate. To contribute to this debate, we constructed a power-model which relates the number of fatal crashes to speed raised to the power four. Despite its simplicity, this model fitted the data well. Notably, it enabled the fractions of fatal crashes attributable to various levels of speeding to be estimated. Data for secondary roads over the period 2001–2010 showed that the fraction of fatal crashes attributable to high-level speeding (>20 kph over the speed limit) decreased from 25% to 6% and that attributable to medium-level speeding (10–20 kph over the speed limit) decreased from 13% to 9%, whereas that attributable to low-level speeding progressively increased from 7% to 13%. Similar trends were observed on main roads. These results highlight the effectiveness of the speed regulation policies introduced during the study period with respect to high-level speeding. They also suggest that future policy should focus on low and medium-level speeding in order further to reduce road deaths significantly, since these levels now correspond to the major fraction of fatal crashes.

Analysis of the scientific productivity of researchers from the Republic of Croatia for the period 1990–1992

The scientific production of researchers from the Republic of Croatia, consisting of the published papers with addresses of the institutions from Croatia only, was analyzed for the period 1990–1992, covering 2047SCI, SSCI, andA&HCI registered papers. The source index ofSCI has registered 1912 (92.50% of total number of published articles) papers,SSCI 118 (5,71%), andA&HCI 37 (1.79%) papers, respectively. The papers were published in more than 700 different journals, covering 122 scientific subfields. The most frequently used journals are the nationalPeriodicum Biologorum, Croatica Chemica Acta andCollegium Antropologicum with 236 published papers or 11.5%. The largest number of papers have been published in scientific subfields:Biology (146 papers),Chemistry (107), andPhysics of Condensed Matter (102). The average paper was published by 3.57 researchers, but subfields ofNuclear Physics (7.40 authors per paper),Immunology (5.67), andHematology (5.60) were with the highest authorship. The partial contributions of institutions were also determined, and the most productive were Ruder Bokovi Institute with 645.0, the Faculty of Medicine with 396.7, and the Faculty of Science and Mathematics with 201.7 published papers, respectively. The average quality of the used journals were estimated; Institute of Physics, Ruder Bokovi Institute, and the Faculty of Science and Mathematics published their papers in journals with bigger impact factor (higher quality) than average institutions. Publications were divided by the type of papers, most frequent being articles (1778 publications, 86.85%), notes (117, 5.71%) and letters (56, 2.74%), respectively. Scientific subfield distribution of papers published by the most productive institutions were also analyzed.     

An overview of iris recognition: a bibliometric analysis of the period 2000–2012

Person identification based on iris recognition is getting more and more attention among the modalities used for biometric recognition. This fact is due to the immutable and unique characteristics of the iris. Therefore it is of utmost importance for researchers interested in this discipline to know who and what is relevant in this area. This paper presents a comprehensive overview of the field of iris recognition research using a bibliometric approach. Besides, this article provides historical records, basic concepts, current progress and trends in the field. With this purpose in mind, our bibliometric study is based on 1,354 documents written in English, published between 2000 and 2012. Scopus was used to perform the information retrieval. In the course of this study, we synthesized significant bibliometric indicators on iris recognition research in order to evaluate to what extent this particular field has been explored. Thereby, we focus on foundations, temporal evolution, leading authors, most cited papers, significant conventions, leading journals, outstanding research topics and enterprises and patents. Research topics are classified into three main categories: ongoing, emerging, and decreasing according to their corresponding number of publications over the period under study. An analysis of these indicators suggests there has been major advances in iris recognition research and also reveals promising new avenues worthy of investigation in the future. This study will be useful to future investigators in the field.     

Gender differences in science: the case of scientific productivity in Nano Science & Technology during 2005–2007

Although, women’s contribution to science is crucial to social development, gender difference has been for a long time affecting the quantity and quality of scholarly activity. In spite of some improvements, women are still suffering from gender gap and biases in science world. Using a scientometric method with a comparative approach, the present communication aims to study women performance in Nano Science & Technology in terms of their scientific productivity and impact and to contrast them to their male counterparts. The significance of the study relies on the importance of a balanced development of human society in general and in different scientific milieus in specific. According to the research results, although female Nano-researchers are scarce in number, they equally perform in terms of scientific productions and impacts. That may imply gender egalitarianism in the field.

What publications metadata tell us about the evolution of a scientific community: the case of the Brazilian human–computer interaction conference series

Human–computer interaction (HCI) is a research field which engages different disciplines, interest groups and communities, and which has emerged in different countries at different times. To understand how the HCI research community has evolved in Brazil, this paper applies data and visual analytics to its main conference series, the Brazilian Symposium on Human Factors in Computing Systems, henceforth IHC. We have explored the metadata of all 340 full papers published in the 14 editions of IHC. Our goal was to investigate the evolution of the Brazilian HCI community so we can raise the level of “self-knowledge” and thus discuss strategies that can further help develop this research community. From our analysis, we could understand more deeply the authorship profile of our community and how it has changed over time, the co-authorship networks evolution, the prominent institutions and states, the reference profile and the research topics over time. We hope that this paper will contribute to inspire other scientific communities to analyze themselves, and encourage their own discussions.

Bibliometric analysis of diabetes mellitus research output from Middle Eastern Arab countries during the period (1996–2012)

The main objective of this study was to analyze research productivity originating from Middle East Arab (MEA) countries in the field of diabetes mellitus (DM). Data from January 1, 1996 till December 31, 2012 were searched for documents with specific words in diabetes as a “source title” and a list of 13 MEA countries as affiliation country. Research productivity was evaluated based on number of publications, citation analysis, indexing in Institute for Scientific Information and impact factor (IF). The 13 MEA countries published a total of 479 documents in 41 diabetes journals. This number represents 0.75 % of the total documents produced globally in the field of DM. The number of published documents increased by around fivefold from early 2000 to 2012. Of the 41 journal titles retrieved, 24 (58.5 %) had their IF listed in the journal citation reports 2012. Forty-two documents (14.5 %) were published in journals that had no official IF. The total number of citations for documents published from MEA countries in the field of DM, at the time of data analysis, was 5,565 with an h index of 35. The median (inter-quartile range) citation for documents from the 13 MEA countries was 4 (1–11). The top productive institution in the field of DM was United Arab Emirates University with 51 documents (10.6 %). Authors from MEA countries collaborated mostly with authors in countries like United Kingdom, USA, and Germany. The present data show promising and relatively good diabetes research productivity in MEA countries especially after 2008.     

Evolution of bicycle helmet use and its determinants in France: 2000–2010

This paper aims to analyse helmet use in France, as a voluntary behaviour rather than a legal requirement, promoted by public awareness campaigns. It aims to investigate the determinants of helmet wearing and to explore its evolution from 2000 to 2010. The analysis relies on data from a series of general population surveys called “Health Barometers”: 2000 (n = 13,163), 2005 (n = 25,651) and 2010 (n = 8573). Multivariate logistic regressions were used to identify factors associated with helmet use and time trends. Nearly half of the 15–75 year olds surveyed reported that they rode a bicycle, and among these cyclists, 22.0% reported that they wore a helmet on their last ride. Further analysis by gender reveals that twice as many men than women wore helmets. Over the last decade, helmet use among cyclists has clearly increased, from 7.3% in 2000 to 22.0% in 2010, whereas the influence of social and economic factors, such as unemployment and wage disparities, appears to have decreased. Several determinants of bicycle helmet use were highlighted. To improve the effectiveness of further public information campaigns on helmet use, the key target groups should include women, under 25 year olds and people living in urban areas. Promoting the wearing of helmets among families should also be enhanced, given the higher rate of helmet use by parents as well as children.     

Duplicate and fake publications in the scientific literature: how many SCIgen papers in computer science?

Two kinds of bibliographic tools are used to retrieve scientific publications and make them available online. For one kind, access is free as they store information made publicly available online. For the other kind, access fees are required as they are compiled on information provided by the major publishers of scientific literature. The former can easily be interfered with, but it is generally assumed that the latter guarantee the integrity of the data they sell. Unfortunately, duplicate and fake publications are appearing in scientific conferences and, as a result, in the bibliographic services. We demonstrate a software method of detecting these duplicate and fake publications. Both the free services (such as Google Scholar and DBLP) and the charged-for services (such as IEEE Xplore) accept and index these publications.     

Research performance of Turkish astronomers in the period of 1980–2010

We investigated the development of astronomy and astrophysics research productivity in Turkey in terms of publication output and their impacts as reflected in the science citation index for the period 1980–2010. Our study involves 838 refereed publications, including 801 articles, 16 letters, 15 reviews, and six research notes. The number of papers were prominently increased after 2000 and the average number of papers per researcher is calculated as 0.89. Total number of received citations for 838 papers is 6938, while number of citations per papers is approximately 8.3 in 30 years. Publication performance of Turkish astronomers and astrophysicists was compared with those of seven countries that have similar gross domestic expenditures on research and development, and members of organization for economic co-operation and development. Our study reveals that the output of astronomy and astrophysics research in Turkey has gradually increased over the years.     

Assessment of the total effective dose of miners in the underground Rožná Uranium Mine in the Czech Republic during the period 2004-2009

The paper discusses the situation in the Czech Republic regarding past and present uranium mining activities with emphasis on the evaluation of the exposure of underground miners in the Ro?ná Uranium Mine, which is currently the only active mine in the country and practically in the entire European Union. The total effective dose has been summarised taking into account all three major components, namely radon short-lived decay products, long-lived alpha emitters in ore dust and penetrating external gamma radiation. The average and maximum values of the effective dose as well as the collective effective dose of underground miners are also presented. The purpose of the paper is to document the miners' exposures during a period of 6 years in a uranium mine where conditions including the ore grade and methods of mining showed recently some changes that may affect the individual components of the total effective dose.     

Investigating different types of research collaboration and citation impact: a case study of Harvard University’s publications

This study aims to investigate the influence of different patterns of collaboration on the citation impact of Harvard University’s publications. Those documents published by researchers affiliated with Harvard University in WoS from 2000–2009, constituted the population of the research which was counted for 124,937 records. Based on the results, only 12% of Harvard publications were single author publications. Different patterns of collaboration were investigated in different subject fields. In all 22 examined fields, the number of co-authored publications is much higher than single author publications. In fact, more than 60% of all publications in each field are multi-author publications. Also, the normalized citation per paper for co-authored publications is higher than that of single author publications in all fields. In addition, the largest number of publications in all 22 fields were also published through inter-institutional collaboration and were as a result of collaboration among domestic researchers and not international ones. In general, the results of the study showed that there was a significant positive correlation between the number of authors and the number of citations in Harvard publications. In addition, publications with more number of institutions have received more number of citations, whereas publications with more number of foreign collaborators were not much highly cited.
