Due to the tremendous increase and variation in serial publications, faculties in department of university are finding it difficult to generate and update their departmental core journal list regularly and accurately, and libraries are finding it difficult to maintain their current serial collection for different departments. Therefore, the evaluation of a departmental core journal list is an important task for departmental faculties and librarians. A departmental core journal list not only helps departments understand research performances of faculties and stu- dents, but also helps librarians make decisions about which journals to retain and which to cancel. In this study, a Computer-Aided Bibliometrics System was implemented and two methodologies (JCDF and LibJF) were proposed in order to generate a departmental core journal ranking list and make the journal citationanalysis. Six departments were taken as examples, with MIS as the major one. One journal citation pattern was found and the ratio of Turning point-to-No. journal was always around 0.07 among the 10 journals and 6 departments. After comparing with four methodologies via overlapping rate and standard deviation distances, the two proposed methodologies were shown to be better than question- naire and library subscription method.

Abstract: The objective of this paper is to present the use of CitationAnalysis (CA) technique together with the Social Network Analysis (SNA) to identify the most referenced authors in the publications that address the issue of science education in the CAPES Journals Portal (CAPES is a governmental Brazilian foundation dedicated to the capacitation of Universities professors and researchers). The search for publications on science education at the CAPES Portal was held, which retrieved 42 publications including articles, proceedings and theses. After evaluation, 25 articles were selected for analysis of their bibliographic data with the use of EndNote software. The generation and analysis of the network of authors was performed with the aid of UCINET software, suitable for SNA. Based on the metric analysis of Centrality Degree, the authors most referenced on the network were Matthews, UNESCO, Aikenhead, Bakhtin, Chassot, Morin, Santos and Vygotsky, indicating the visibility and influence of these authors in the field of Science Education. In brief CA along with SNA are shown to significantly contribute to the study of scientific communication, enabling to distinguish the main authors and references of a theme or field of knowledge.
The following study is a citationanalysis w h i c h a i m s t o a c t a s a r e f e r e n c e p o i n t f o r librarians working in this field. While it has been said that “no measure of journal use other than one derived from a local-use study is of any significant practical value to libraries” (Line, 1978, p. 313), it should also be noted that citationanalysis is not undertaken solely for purposes of collection development and maintenance, although it may be useful in this regard. An understanding of the scope of relevant resources contributes to more effective library instruction and result consultations, and citation analyses serve as useful reference points for accreditation and reaccreditation, during which local use data may be insufficient.
In the second phase of this analysis, conducted in January 2014, I attempt a more comprehensive cited reference search in WoS to generate citation counts to all editions of the WOA/WOD over time. Since WOA/WOD originally was, and still is, distributed as a print publication, it seems likely that formal citations to this data set would be more numerous than for the other data sets analyzed here. To allow for wide variance in citation formats, I search for the author(s) and publication year(s) of each edition of the WOA/ WOD and then manually select the relevant search results. The search strategies used in this process are summarized in Table 2. The process of executing these search strategies for one edition of the WOA/WOD is as follows. First, I perform a Cited Reference Search using the search criteria listed in Table 2. In step 2 of the Cited Reference Search process, I select the relevant citation variants through manual inspection of the step 1 results, and manually count the number of cited reference variants selected. After retrieving the final list of citing articles, I then analyze the results using the tools provided by WoS to obtain citation counts per year, subject category, and country for that edition of the WOA/WOD. I then repeat this process for each subsequent edition of the WOA/WOD.
fers to the rate of citing papers that have been published by the same author/journal. In general, the moderate self- citing rate shows the influence and role of a journal in the discipline, but the higher self-citing rate shows the limita- tion of the information absorption from other sources. Cross citing rate refers to the citing/cited rate each other among the collection of journals. The present study adopts a descriptive research approach by means of bibliometric analysis.
This work aims promoting an understanding of internationalization in higher education, as part of a broader research exploring its dimensions from the Information Science. Its aim is to identify the most significant work in this area and analyze their intellectual structure, from which reflections on the implications for the establishment of university policies are made. For this, a citation and cocitation analysis of scientific literature on the subject registered in the Scopus database and a documentary analysis of the most cited articles is performed. Multivariate analysis techniques as cluster analysis and multidimensional scaling are used. The study clusters authors and journals on topics as Concepts and models of internationalization; Intercultural communication; International mobility and migration; Neoliberalism, globalization and academic capitalism. The key aspects identified allowed reflecting on internationalization policies discussions, including the motivations and objectives of internationalization and the dichotomy between the search for international visibility and intercultural dimension.
Abstract: This work is part of master's research project, which aims to collect and analyze the citations in theses and dissertations at the tropical botany master and doctoral degrees of the National School of Tropical Botany between the years 2005 and 2014. The first step, referring to theses, is already completed and is the object of this work. Citations of these theses were analyzed with regard to: document type, languages of publication and periodical titles. As a result, 46 theses, mentioning 4,106 references, were identified, an average of just over 89 references per work. Most of the citations are in periodicals, followed by books as preferred channels of scientific communication of this community. Regarding the language, the most cited was English, followed by Portuguese. The third most cited language was Latin, due to be widely used in the first descriptions of plants, characteristic of this study area. It was identified 654 periodical titles, which features 24 through the application of Bradford's Law. It is observed that the most cited journal was Rodriguésia published by Botanical Garden of Rio de Janeiro Research Institute. Once completed, the mapping of scientific production by citationanalysis can be applied to identify the main sources feeding an area of knowledge, serving as an evaluation tool of the institution's library collection.

Whereas text-mining approaches are used in cases in which references are not stated, citationanalysis approaches usually deliver superior results as e.g. synonyms and unclear nomenclature do not lead to misleading results [3, 4, 5]. Many citationanalysis approaches exist and they all have their own strengths and weaknesses for identifying similar documents. Among the most widely used are the easily applicable ‘cited by’ approach, which considers papers as relevant that cite the same input document and the ‘reference list’ approach, which considers papers as relevant that were referenced by the input document. The best results can usually be obtained by bibliographic coupling and co-citationanalysis, which allow calculating the coupling strength . These approaches, which were already invented in the 60s and 70s, are used by scientists and on academic search engine websites like CiteSeer1 .
Neotropical Ichthyology citationanalysis pointed to Bertaco, V. A. (52 citations), Costa, W. J. E. (32 citations), and Ribeiro, A. C. (30 citations) as the most often cited authors. The articles that had been most often cited in the period between 2006 and 2010 were found to be “Tectonic history and the biogeography of the freshwater fishes from the coastal drainages of eastern Brazil: an example of faunal evolution associated with a divergent continental margin”, by Alexandre Cunha Ribeiro, cited 26 times; “Putative relationships among inseminating and externally fertilizing characids, with a description of a new genus and species of Brazilian inseminating fish bearing an anal-fin gland in males (Characiformes: Characidae)” by Stanley H. Weitzman, Naércio A. Menezes, Hans-Georg Evers and John R. Burns, cited 23 times; followed by “Two new species of Astyanax (Ostariophysi: Characiformes: Characidae) from eastern Brazil, with a synopsis of the Astyanax scabripinnis species complex” written by Vinicius A. Bertaco and Carlos A. S. de Lucena, cited 18 times. Neotropical Ichthyology was cited by 171 different journals published in the five continents. Of the total, 107 journals were responsible for just one citation , which indicates that Neotropical Ichthyology has a wide range of readers. However, self-citation amounted to 26.8%, 172 of the total 642 citations. The Zootaxa
This bibliometric study carried out during the 1998- 2017 period has allowed a number of conclusions to be drawn in line with the objective established in the introductory section of this paper. The exploration of the literature on CR and dementia from WoS databases has outlined the evolutionary trajectory of the collective knowledge over the past twenty years and highlighted the areas of active pursuit and future research. Based on the network visualization and document co-citationanalysis using CiteSpace and VosViewer, this study evaluated emerging trends and patterns of publications, citations, journals, institutions, and areas of research in the literature. The top clusters covered a range of inter- ests, reflecting the interdisciplinary nature of CR and dementia. They are foundational to the field of research. To the best of our knowledge, this study represents the first attempt to apply CiteSpace to explore and visu- alize CR and dementia knowledge. It is one of only a few investigations that have focused on co-citations as a marker of development of this domain from different perspectives. The findings of the present investigation demonstrate the potential of bibliometric visualization techniques for studying the scientific literature.
Abstract: The citationanalysis has been used as much as an object of study as a methodology in related studies to Metric Studies, in order to establish and to improve indicators for the scientific periodical production analysis and evaluation. Despite its limitations, citation studies can be used to infer about the maturity degree of the scientific activity. Therefore, this study seeks to expand possibilities to solve the problems faced by using these indicators. The study aims to analyse the relationships of journals self-citation, which publish researches related to Metric Studies on Scopus database in a specific corpus of 132 articles, published until 2014, resulting from the intention of embracing the interdomain of Metric Studies between Information Science and Medicine. After exporting the corpus of articles and their respective references, from Scopus to Excel, the citing titles and the cited titles at the references of each article were cleaned and standardized in order to use VantagePoint Software to generate the matrix with the number of self-citation of each journal. The analysis model built, relates the number of journals self-citations with their Impact Factor and the H index given by SJR to these journals, identifying their country of provenance, their frequency and occurrence number in the corpus. Among the 40 journals analysed, 13 of them practice self-citation. Among the latter, those with the highest impact factor and H index are coming from the US and UK. It should be noted that 12 journals are Brazilian and eight of them have self-citation. Of the latter, the Braz J Med Biol Res has a higher H index and Impact Factor compared to the other journals, however, it has a small number of self-citation if compared to the other national journals, which have more self-citation and a lower visibility, according to the impact indicators analysed. That’s the case of the Acta Cirúrgica Brasileira and of the Arquivos Brasileiros de Oftalmologia, that coincidentally, have their impact ranking values proportional to the average self-citations.

Specimens from two populations of Astyanax altiparanae and one of Hyphessobrycon eques were collected in streams from the upper Paraná river basin (Fig. 1). The indi- viduals were anesthetized with benzocaine (5%) and then sacrificed for subsequent cytogenetic analysis. The processed specimens were fixed in 10% formalin and stored in 70% alcohol for further taxonomic studies. The preserved specimens were placed in the collection of fish from Laboratório de Biologia e Genética de Peixes (LBP), Depar- tamento de Morfologia do Instituto de Biociências da UNESP, campus de Botucatu. Their deposit numbers are indicated below.
Methodology: In this paper, we present a new, automated method that produces estimates of an individual’s publication- citation record from an individual’s name and a set of domain-specific vocabulary that may occur in the individual’s publication titles. Because this vocabulary can be harvested directly from a research web page or online (partial) publication list, our method delivers an easy way to obtain estimates of a publication-citation record and the relevant citation indices. Our method works by applying a series of stringent name and content filters to the raw publication search results returned by an online publication search engine. In this paper, our method is run using Google Scholar, but the underlying filters can be easily applied to any existing publication search engine. When compared against a manually constructed data set of individuals and their publication-citation records, our method provides significant improvements over raw search results. The estimated publication-citation records returned by our method have an average sensitivity of 98% and specificity of 72% (in contrast to raw search result specificity of less than 10%). When citation indices are computed using these records, the estimated indices are within 10% of the true value, compared to raw search results which have overestimates of, on average, 75%.
Main strength our report was analyses of four nationally respresentative NDHSs spanning two decades. NDHSs done on a reasonably large sample of women of child bearing age group are often useful resources of child mortality data in countries where vital registration systems are weak. Standardised protocols and questionnaires allow cross-country comparisons and time trend analysis. Another strength was availability of most recent survey data to forecast, if Nepal would achieve MDG-4 considering the current child mortality experience. As recommended by King et al. by calculating both absolute and relative measures we could gauge inequalities according to various sub groups. In particular, HR ratios obtained by Cox regression analyses provided a more detailed interpretation of inequalities considering the effect of specific factors and covariates. Houweling et al. have emphasised the advantage of odds ratio over the RR and RD as measures of inequalities. Nevertheless, there were some limitations of using cross-sectional household survey data. The first one is about recall bias for exact date of birth, particularly in countries where mother's literacy levels are low and birth certificates for verification are unavailable for all children. In NDHS, complete birth history documents month and year only, leading to imprecise calculation of survival periods. Detection of smaller mortality reductions observed in recent NDHSs may have needed larger sample sizes owing to cluster sampling design used in NDHS. However, the samples used in all four NDHSs were not large enough leading to insufficient statitsical power for trend analysis as reported by previous studies based on DHS data for calculation of U5MR[16,21]. Therefore, projections made for the year 2015 may not be precise since about 60% of births in Nepal still take place at home without presence of a skilled attendant and most of the neonatal deaths occuring within first 24 hours at home may go unreported.
Meta-analysis is considered to be a powerful tool for pooling the results from different studies in complex traits, because of the relative improved statistical power achieved with larger sample sizes . We therefore conducted a meta-analysis of seven published articles from different populations and the results from our case-control study by a random-effects model. Based on all three genetic models using the Peto method, CETP 405V was indicated as a longevity risk allele in the overall populations (Table 5). When stratified by ethnicity, only the study of Ashkenazi Jews indicated a protective role for Figure 4. Begg’s funnel plot of CETP I405V polymorphism to detect publication bias. (A) allele contrasts (405V vs. 405I); (B) dominant model (405VV+VI vs. II); (C) recessive model (405VV vs. VI+ II).
