AbstractThis thesis is about the visual analysis of author impact and other bibliometric data such as an authorspublication history. It utilizes Publish or Perish as a data source, which is a search tool to find thisbibliometric data. Bibliometric data is a concept within Bibliometrics with which to find and definenotable publications, to draw a number of different conclusions, such as how much impact an authorhas had in a given field. To do this we use information visualization techniques. InformationVisualization is a field of science about increasing insight and understanding of raw data. It does this byresearching on details of human cognition and perception and how data itself is modeled, and bycategorizing and developing new ways to encode and interact with data visually.Since Publish or Perish only gives its information as a raw text feed, and do not allow for anyreal comparisons between authors, this thesis tries to rectify this by introducing a web basedvisualization tool to analyze this data. The data itself consists of a number of scientifically definedindexes which measures an author's impact in his given field, an overview of his publication history,and some general bibliometric data.

Abstract This interdisciplinary study describes in the first part the frequency with which various statistical research designs and methods are reported in psychiatric journals, and investigates how the use of these methods affect the visibility of the article in the form of received citations. In the second part focus is specifically on factor analysis, and the study presents two applications of this method. Original research articles (N = 448) from four general psychiatric journals in 1996 were reviewed. The journals were the American Journal of Psychiatry, the Archives of General Psychiatry, the British Journal of Psychiatry and the Nordic Journal of Psychiatry. There were differences in the utilisation of statistical procedures among the journals. The use of statistical methods was not strongly associated with the further utilisation of an article. However, extended description of statistical procedures had a positive effect on the received citations. Factor analysis is a statistical method based on correlations of the variables, which is often used when validity and structure of psychiatric instruments are studied. Exploratory factor analysis is designed to explore underlying latent factors, and in confirmatory factor analysis the aim is to verify the factor structure based on earlier findings in other data sets. Using data from the 31-year follow-up of the Northern Finland 1966 Birth Cohort Study this study aimed to demonstrate the validity and factor structure of scales measuring temperament (Tridimensional Personality Questionnaire, TPQ, and Temperament and Character Inventory, TCI) and alexithymia (20-item Toronto Alexithymia Scale, TAS-20). The results of exploratory factor analysis indicated good performance of the TCI and TPQ, though the results suggested that some developmental work is still needed. Of the two scales, the TCI worked psychometrically better than the TPQ. A confirmatory factor analysis showed that the three-factor model of TAS-20 was in agreement with the Finnish version of the scale. To conclude, future authors of psychiatric journals might apply these results in designing their research to present intelligible and compact analysis combined with a high quality presentation technique. Results of the factor analyses showed that the TPQ, TCI and TAS-20 can be used also in their Finnish versions. / Tiivistelmä Tämä poikkitieteellinen tutkimus kuvaa erilaisten tilastotieteellisten menetelmien yleisyyttä ja merkitystä psykiatriassa. Tutkimuksen ensimmäisessä osassa tutkitaan erilaisten tilastomenetelmien ja tutkimusasetelmien osuutta psykiatrisissa artikkeleissa ja lisäksi käytettyjen menetelmien vaikutusta artikkelien saamien viittausten lukumäärään. Tutkimuksen toisessa osassa keskitytään faktorianalyysiin ja esitetään kaksi siihen liittyvää sovellusta. Aineiston muodostavat alkuperäistuloksia esittelevät artikkelit (N = 448) neljästä eri psykiatrian tieteellisestä yleislehdestä vuodelta 1996. Kyseiset lehdet ovat American Journal of Psychiatry, Archives of General Psychiatry, British Journal of Psychiatry ja Nordic Journal of Psychiatry. Lehdet erosivat toisistaan tilastotieteellisten menetelmien käytössä ja tulosten esittämisessä. Tilastotieteellisten menetelmien käytöllä ei ollut suurta vaikutusta artikkelien saamien viittausten lukumäärään, mutta laajalla menetelmien kuvauksella oli positiivinen vaikutus viittausten lukumäärään. Faktorianalyysi on tilastotieteellinen tutkimusmenetelmä, jota käytetään tutkittaessa millaisista osatekijöistä erilaiset monimutkaiset ilmiöt koostuvat. Erityisesti tutkittaessa psykiatristen mittareiden validiteettia ja rakennetta faktorianalyysi on osoittautunut hyödylliseksi. Eksploratiivisessa faktorianalyysissa tarkoituksena on etsiä taustalla olevia piileviä muuttujia ja konfirmatorisessa faktorianalyysissa tarkoitus on vahvistaa aiemmissa tutkimuksissa todettu mittarin faktorirakenne. Tässä tutkimuksessa hyödynnetään aineistoa Pohjois-Suomen vuoden 1966 syntymäkohortin 31 vuoden seurannasta. Aineiston avulla tutkitaan temperamenttia (Tridimensional Personality Questionnaire, TPQ, ja Temperament and Character Inventory, TCI) ja aleksitymiaa (20-item Toronto Alexithymia Scale, TAS-20) tutkivien mittareiden suomenkielisten käännöksien validiteettia ja faktorirakennetta. Eksploratiivisen faktorianalyysin tulokset kertoivat, että TPQ ja TCI toimivat hyvin myös suomenkielellä. Kuitenkin mittareissa on vielä kehittämisen varaa. TCI:n psykometriset ominaisuudet olivat paremmat kuin TPQ:n. Aleksitymiamittarin TAS-20 konfirmatorinen faktorianalyysi osoitti että aiemmin julkaistu kolmen faktorin malli toimi hyvin myös suomalaisella versiolla. Psykiatristen artikkelien kirjoittajat voivat hyödyntää tämän tutkimuksen tuloksia suunnitellessaan psykiatrista tutkimusta suuntaan, jossa selkeä ja tiivis tulosten analysointitapa ja korkealaatuinen tulosten esitystapa korostuu. Faktorianalyysi soveltuu hyvin mittarin validiteetin tutkimiseen. Tutkimus osoitti TPQ-, TCI- ja TAS-20-mittareiden suomenkielisten versioiden validiteetin.

This research is a descriptive bibliometric study of the literature of the field of Korean studies. Its goal is to quantitatively describe the literature and serve as a model for such research in other area studies fields. This study analyzed 193 source articles and 7,166 citations in the articles in four representative Korean and Asian studies journals published in North America from 1977 to 1996. The journals included in this study were Korean Studies (KS), the Journal of Korean Studies (JKS), the Journal of Asian Studies (JAS), and the Harvard Journal of Asiatic Studies (HJAS). Subject matters and author characteristics of the source articles were examined, along with various characteristics such as the form, date, language, country of origin, subject, key authors, and key titles of the literature cited in the source articles. Research in Korean studies falls within fourteen broad disciplines, but concentrated in a few disciplines. Americans have been the most active authors in Korean studies, followed closely by authors of Korean ethnicity. Monographic literature was used most. The mean age of publications cited was 20.87 and the median age of publications cited was 12. The Price Index of Korean studies as a whole is 21.9 percent. Sources written in English were most cited (47.1%) and references to Korean language sources amounted to only 34.9% of all sources. In general, authors preferred sources published in their own countries. Sources on history were cited most by other disciplines. No significant core authors were identified. No significant core literature were identified either. This study indicates that Korean studies is still evolving. Some ways of promoting research in less studied disciplines and of facilitating formal communication between Korean scholars in Korea and Koreanists in North America need to be sought in order to promote well-balanced development in the field. This study suggests that as many and as great a variety of titles in all formats as possible need to be collected to support research in Korean studies.

El presente estudio tuvo por objetivo realizar un estudio bibliométrico sobre los artículos científicos de Psicología sobre niños diagnosticados con TDAH, recogidos de la base de dato Redalyc - Revistas de Latinoamérica. Para ello, se realizó una búsqueda de la variable de interés encontrando 24 estudios, de los cuales finalmente, quedaron 4 seleccionados por los criterios de inclusión. Por medio del análisis de los datos, se encontró que la mayoría de estudios no contaba con doi, orcid, hipótesis, ni recomendaciones. Asimismo, los estudios se caracterizaron por usar instrumentos de medición mixtos (cuestionarios y entrevistas). Se concluye que existe una gran necesidad en continuar investigando las alteraciones y dificultades concomitantes que manifiestan los niños diagnosticados con TDAH, debido al impacto que tiene sobre su adaptación social, escolar y familiar. / The objective of the present investigation was to perform a bibliometric study on the scientific articles of Psychology on children diagnosed with ADHD, collected from the Redalyc - Latin American Magazines database. For this, it has been made a search for the variable of interest, finding 24 studies, of which, finally, 4 were selected by the inclusion criteria. Through data analysis, it was found that most studies did not have doi, orcid, hypotheses, or recommendations. Likewise, the studies were characterized by using mixed measurement instruments (questionnaires and interviews). It is concluded that there is a great need to continue investigating the concomitant alterations and difficulties manifested by children diagnosed with ADHD, due to the impact it has on their social, school and family adaptation. / Trabajo de investigación

In this thesis, I draw attention to patterns at the intersection of (a) interpretations of science in two journals (Philosophy of Science, and Social Studies of Science) and (b) references to Wittgenstein's writings. Interpretations of science can be classed according to the degree to which they support a realist or social constructivist understanding of the entities described by current scientific theories. By tracing the intellectual traditions from which these interpretations emerged, I develop an abstracted classification of these positions. Since this classification does not meaningfully map onto the positions articulated by the writers sampled here (which is telling about intellectual histories generally), I develop a new, more promising scheme of classification. I find that Wittgenstein is appropriated more often in support of social constructivist views of science, but that reasons for this support are generally weak. Using a novel measure of content which I call "appeal-to-authority," I show that there is a significant difference between these journals in their use of Wittgenstein's writings. But there is a subtle methodological argument at work here as well. I show that methods of analysis which rely exclusively on intellectual histories, bibliometrics, and globablizing statements about the products of science suffer serious limitations. In short, this thesis reflexively shows that the methods upon which it is based allow room for considerable bias and manipulation, and thereby implicates many bodies of work built upon these methods. / Master of Science

This research examines scientific productivity among authors in natural scientific reference groups. A broad literature review surveys models of knowledge production, including measures of scientific products at different levels of abstraction. Data is drawn from authors in ten specialty areas, elites identified by co-citation analysis. These co-citation clusters are analyzed in general, in disciplinary sets, and as specialty groups. Results show that variance in the productivity of elite authors is not predictable on the basis of stratification variables. Descriptive differences in disciplines and specialties reflect contextual diversity in the social production of scientific knowledge. Differences in average annual paper publication, citation and highly cited paper publication do not correspond to differences in career age, job sector or prestige of highest degree. In general, stratification by experience and affiliation is not reflected in the variation of bibliometric measures of scientific productivity. This suggests that co-citation clusters are partially comparable to general populations of science, since author productivity is not simply predicted on the basis of social stratification for either type of population. Co-citation cluster authors are heterogeneous, like scientists in general, and their bibliometric differences do not correspond to variation in experience or affiliation. / Master of Science

No. of bitstreams: 1 Gilberto_Caetano.pdf: 626973 bytes, checksum: d5e81868517dfe9728b1dad8534972d7 (MD5) Previous issue date: 2010-03-31 / This dissertation is a bibliometric study of scientific articles on Internal Control and Risk Management presented and published at the USP Congress on Financial Control and Accounting and at EnANPAD between 2001 and 2008. The subject was chosen because of the importance and current relevance that Internal Control and Risk Management have taken on in the global and complex society of today. Researching the evolution and theoretical concepts related to these issues has become essential nowadays. The research method employed was the descriptive one, of the survey type, with a quantitative focus and bibliographical and documental characteristics. Of the 6,960 articles presented and published by the USP Congress and EnANPAD in the period 149 (2.1% of the total 6,960) were selected, 90 from EnANPAD and 59 from the USP Congress. This was the volume of articles used in the research. The application of Lotka's Law showed in this study that there is not yet an elite group of authors that have written on Internal Control and Risk Management at the USP Congress and at EnANPAD. The study also revealed that: in the two events taken together the quantity of articles signed by up to two authors in the period reached 49% of the total (44.1% in the USP Congress and 52.3% at EnANPAD); 78.6% are male; 68.1% of them are University lecturers; and that only 23.5% of the articles on Internal Control and Risk Management at the USP Congress and EnANPAD were published afterwards in specialist periodicals. / Esta disserta????o trata do estudo bibliom??trico dos artigos cient??ficos que abordam a tem??tica Controle Interno e Gest??o de Riscos apresentados e publicados no Congresso USP de Controladoria e Contabilidade e no EnANPAD entre 2001 e 2008. Tal tema foi escolhido em fun????o da import??ncia e da atualidade que assume em uma sociedade globalizada e complexa como a atual, de forma que pesquisar sobre a evolu????o e os conceitos te??ricos relacionados a esses assuntos tornou-se imprescind??vel nos dias de hoje. O m??todo de pesquisa empregado foi o descritivo, do tipo levantamento, com enfoque quantitativo e com caracter??sticas bibliogr??fica e documental. Do total de 6.960 artigos apresentados nos eventos supracitados, selecionaram-se 149 (2,1%), sendo 90 do EnANPAD e 59 do Congresso USP. Esse foi o volume de artigos utilizados na pesquisa. O presente estudo demonstrou, por meio da aplica????o da Lei de Lotka, que ainda n??o existe uma elite de autores que escrevem sobre Controle Interno e Gest??o de Riscos no Congresso USP e no EnANPAD. Revelou ainda que, no somat??rio de ambos os eventos, a quantidade de artigos assinada por at?? dois autores no per??odo chegou a 49% do total (44,1% no Congresso USP e 52,3% no EnANPAD); 78,6% dos autores s??o do sexo masculino; 68,1% deles s??o professores universit??rios; e que somente 23,5% dos artigos foram publicados posteriormente em peri??dicos especializados.

This thesis provides an in-depth study of the possibilities of applying bibliometric methods to the research field of literary studies. The four articles that constitute the backbone of this thesis focus on different aspects of references and citations in literary studies: from the use of references in the text to citation patterns among 34 literature journals. The analysis covers both an Anglo-Saxon context as well as research in Swedish literary studies, and the materials used include Web of Science data, references in the Swedish literature journal TFL (Tidskrift för Litteraturvetenskap) and applications to the Swedish Research Council (Vetenskapsrådet). A study is also made of the influence of one single publication—Walter Benjamin’s Illuminations—and its impact in literary studies and in wider academia. The results from the four articles are elaborated upon using a theoretical framework that focuses on differences in the social and intellectual organization of research fields. According to these theories literary studies can be described as a fragmented, heterogenic, interdisciplinary and ‘rural’ field with a diverse audience. The fragmented and rural organization of the field is reflected in low citation frequencies as well as in the difficulties in discerning research specialities in co-citation mappings, while the analysis of the intellectual base (highly cited authors) is an example of the heterogenic and interdisciplinary character of the field, as it includes authors from many fields across the humanities and the social sciences. The thesis emphasizes that bibliometric studies of research fields in the humanities need to incorporate non-English and non-journal publications in order to produce valid and fair results. Moreover, bibliometric methods must be modified in accordance with the organization of research in a particular field, and differences in referencing practices and citation patterns ought to be considered. Consequently, it is advised that bibliometric measures for evaluating research in these fields should, if used at all, be applied with great caution. / <p>© Björn Hammarfelt 2012</p>

L’objectif de ce travail est de contribuer à l’évaluation d’une politique publique : celle de l’Algérie en matière de recherche scientifique et technique. Nous nous limitons à l’espace de la recherche universitaire et à la période (troublée) de 1990-1999. La thèse s’inscrit dans le domaine de la sociologie des sciences. Le chapitre 1 souligne ce que nous devons aux études Mertoniennes (communautés scientifiques), à la révélation de "lois" de la production, et aux études sur les réseaux scientifiques. Nous empruntons aussi à la politique des sciences et de l’innovation. Le chapitre 2 spécifie le contexte Algérien, et les questions et procédures qu’il suggère. Au chapitre 3 nous exposons nos parti-pris méthodologiques (enquête directe : par questionnaire, et enquête indirecte : bibliométrique). Nous détaillons les outils utilisés. La 2° partie du travail (chapitres 4 à 7) expose les résultats. Le questionnaire aux chercheurs (chapitre 4), même décevant, a permis d’approcher leurs origines sociales et leurs pratiques professionnelles. La bibliométrie (chapitre 5) livre une vue d’ensemble de la production algérienne, de son évolution, de ses spécialités (bien particulières) et de son impact Nous entrons ensuite dans le détail de la répartition des capacités, par villes et par institutions. Le chapitre 6 est consacré à l’analyse des réseaux associant villes, institutions et co-auteurs nationaux ou internationaux. Il révèle quelques résultats des plus originaux. Le chapitre 7 enfin traite de la coopération scientifique internationale. L’ensemble de ces données nous permet d’ouvrir en conclusion une discussion sur la politique scientifique, passée et envisageable pour l’avenir. Le débat est ouvert : il n’est pas de solution universelle. / The objective of this work is to contribute to the assessment of a public policy: the one concerning Algerian scientific and technical research. We limit our study to the space of the academic research and to the troubled period of 1990-1999. The thesis is rooted in the field of the sociology of the sciences. The chapter 1 outlines what we owe to the Mertonian studies (scientific communities), the revelation of "laws" of the production (scientific productivity), and studies on the scientific networks. We also borrow from the literature dealing with science policies and with innovation. The Chapter 2 specifies the Algerian context, and which issues and procedures it suggests. In chapter 3 we present our methodological approach (direct survey through a questionnaire, and indirect approach through bibliometrics. We give a detailed description of the tools and software we have used. The 2nd part of the work (Chapters 4-7) present the results. The questionnaire to the researchers (chapter 4), even disappointing, allowed us to get a glimpse of their social origins and professional practices. The bibliometrics (chapter 5) allows us to get an overview of the Algerian production, its evolution, its specialties (very distinctive) and its impact. We then enter into the details of the distribution of capacities among cities and institutions. The chapter 6 is devoted to the analysis of the networks linking cities, institutions and national or international co-authors. It reveals some of the most original results. Finally, the chapter 7 deals with the international scientific cooperation. The set of these data allows us to open in conclusion a discussion on the scientific policies, past present and advisable for the future. The debate is open: for there is no universal solution.

The dynamic nature of science is embodied in the growth of knowledge in magnitude and the transformation of knowledge in structure. More specifically, the growth in magnitude is indicated by a sharp increase in the number of scientific publications in recent decades. The transformation of knowledge occurs as the boundaries of scientific disciplines become increasingly less distinct, resulting in a complicated situation wherein disciplines and interdisciplinary research topics coexist and co-evolve. Knowledge production in such a context creates challenges for the measurement of science.This thesisaims to develop more flexible bibliometric methodologies in order to address some of the challenges to measuring science effectively. To be specific, this thesis1) proposes a new approach for identifying emerging research topics; 2) measuresthe interdisciplinarity of research topics; 3) explores the accuracy of the journal classification systems of the Web of Science and Scopus; 4) examines the role of cognitive distance in grant decisions; and 5) investigates the effect of cognitive distance between collaborators on their research output. The data used in this thesisaremainly from the in-house Web of Science and Scopus databases of the Centre for Science and Technology Studies (CWTS) at Leiden University. Quantitativeanalyses, in particular bibliometric analyses,are the main research methodologies employed in this thesis. Furthermore, this thesis primarily offers methodological contributions, proposing a series of approaches designed to tackle the challenges created by the dynamics of science. While the major contribution of this dissertation lies in the improvement of certain bibliometric approaches, it also enhances the understanding of the current system of science. In particular, the approaches and research findings presented here have implications for various stakeholders, including publishing organizations, bibliographic database producers, research policy makers, and research funding agencies. Indeed, these approaches could be built into a software tool and thereby be made available to researchers beyond the field of bibliometric studies. / <p>QC 20160406</p>
