Using local citation data to relate the use of journal articles by academic researchers to the coverage of full-text document access systems
The methodology and findings are presented of an empirical study comparing local citation patterns with the holdings lists of a number of sources of journal articles. These sources were the British Library Document Supply Centre (BLDSC and the BL inside service, library holdings, ProQuest Direct, SearchBank, EiText and a linking system including both the Geobase database and the BLDSC. The value of local citation figures is discussed, as is the concept of a 'core' of journal titles, from both theoretical and practical perspectives. Using these figures to represent the local use of journal articles, the coverage of the document sources was found to vary widely. Unsurprisingly, the BLDSC was found to offer the widest coverage. Newer, electronic systems generally fared less well, but may offer other advantages
A systematic review of empirical methods for modelling sectoral carbon emissions in China
© 2019 Elsevier Ltd A number of empirical methods have been developed to study China's sectoral carbon emissions (CSCE). Measuring these emissions is important for climate change mitigation. While several articles have reviewed specific methods, few attempts conduct a systematic analysis of all the major research methods. In total 807 papers were published on CSCE research between 1997 and 2017. The primary source of literature for this analysis was taken from the Web of Science database. Based on a bibliometric analysis using knowledge mapping with the software CiteSpace, the review identified five common families of methods: 1) environmentally-extended input-output analysis (EE-IOA), 2) index decomposition analysis (IDA), 3) econometrics, 4) carbon emission control efficiency evaluation and 5) simulation. The research revealed the main trends in each family of methods and has visualized this research into ten research clusters. In addition, the paper provides a direct comparison of all methods. The research results can help scholars quickly identify and compare different methods for addressing specific research questions

Mapping the knowledge base of information policy: clusters of documents, people and ideas
This thesis investigates aspects of the intellectual and social structure of the field of information policy through a detailed examination of the serials literature. The aims of the research are to explore how information policy scholarship is organised—in terms of its relation to other fields and disciplines; whether it constitutes a distinct specialty in its own right; and what kinds of institutional structures and arrangements exist to support research and scholarship. In Part One, a literature review identifies previous bibliometric and other studies which are relevant to studies of scholarly disciplines and knowledge communities. It discusses the interdisciplinary problem-oriented nature of information policy and considers some of the modes of enquiry which characterise investigations this area. Part Two consists of a series of experiments carried out on a test collection of 771 periodical articles drawn from the Social science Citation Index The empirical work comprised four linked studies: a bibliometric census study an analysis of document clustering; an author cocit.ation study; and a content analysis. Extensive use was made of multivariate statistical techniques, notably principal components analysis, hierarchical clustering, discriminant and correspondence analysis to identify statistically significant and meaningful patterns and structures within the test collection. The study concludes that information policy is a growing and reasonably distinctive field of study with strong links to library and information science, law, media studies, and the political sciences. It is suggested that the field is not unified and that research is still primarily organised along national and traditional disciplinary lines, with little evidence of significant collaborative activity across institutions or sectors. The research base is highly dispersed, with practitioners playing a major role in the production of knowledge. In institutional terms, the field is very thinly spread, with few signs of concentration
Evidence from the Public Sector
The general objective that guided this thesis is to identify the integrated role of information technology capabilities and innovativeness in organizational performance in the public sector. We conducted the present research study in two major stages to achieve this purpose, guided by research questions and specific objectives. We extensively reviewed the scientific literature on innovativeness and IT capabilities applied to the business area first. For this purpose, we used several technological tools to scan several units of analysis underlying each area to identify the origins, conceptual and intellectual structures, and the main active research fronts, indicating open opportunities for the evolution of knowledge. In general, the results showed that knowledge production on the themes is transversal, relating strongly to other topics, such as strategic management, organizational performance, knowledge management and market orientation (innovativeness) and organizational performance, strategic management, and value (IT capabilities). Both themes are recent in the literature, and researchers’ interest proliferates. In addition, there are numerous research opportunities available to future researchers, both about each theme taken in isolation or combined.
The knowledge gathered in the first stage was the basis for the conduction of the second stage, whose approach, markedly empirical, sought to identify the nature of the relationships between the central organizational phenomena of this study (innovativeness and IT capabilities), associated with other under-explored elements in the literature, such as IT reconfiguration capacity and IT human capital. To this end, we analyzed the data provided by 258 Brazilian public institutions from the most diverse segments, collected through a survey conducted with the highest information technology managers. We performed the analyses by applying structural equation models based on covariance (CB-SEM). Overall, the results indicated that the reconfiguration IT capability must be listed among the IT capabilities of public organizations, and innovativeness and IT capabilities play an essential role in the performance of these organizations. The results also indicated that the IT human capital is an antecedent of the IT organizational capabilities. Finally, the results showed that IT capabilities, in turn, have a direct positive effect on organizational performance and are indirectly mediated by innovativeness. The study contributes to the evolution of the literature in IT and innovation to the extent that it helps fill the gap in the lack of studies that use advanced quantitative techniques of bibliometric character to analyze the high-impact scientific production available. In addition, the study presents, in detail, all the steps followed by the study, including the combined use of analysis tools, to allow replication by future researchers. The study innovates and contributes to the advancement of the literature in IT and innovation by identifying that IT capabilities are essential antecedents of organizational innovativeness and the role of IT reconfiguration capability and IT human capital on IT organizational capabilities. Finally, this thesis reveals several research opportunities available and recommended by several recently produced high-impact research.
This study presents managers with recommendations on creating and developing more effective IT teams with more comprehensive skills in the practical field. In addition, the chapter highlights the need for IT managers to dedicate themselves to developing the capability of teams with the expertise to gather, integrate and implement IT resources, with a focus on meeting the needs of organizational processes. Finally, managers are presented with evidence that creating an environment favorable to innovation and supported by information technology is crucial for achieving better corporate results.O objetivo geral que balizou esta tese foi o de identificar o papel integrado das capacidades de tecnologia da informação e da capacidade para inovar no desempenho organizacional, no contexto do setor pĂşblico. Para alcançar esta finalidade, o presente trabalho de investigação foi conduzido em duas grandes etapas, guiadas por questões de pesquisa e objetivos especĂficos. A primeira etapa buscou realizar extensas revisões da literatura cientĂfica sobre os temas capacidades para inovar e capacidades de TI, aplicadas à área de negĂłcios. Para tanto, foram utilizadas variadas ferramentas tecnolĂłgicas para esquadrinhar diversas unidades de análise subjacentes a cada área, a fim de identificar as origens, as estruturas conceituais e intelectuais, bem como as principais frentes ativas de pesquisa, com a indicação de oportunidades abertas para evolução do conhecimento. De forma geral, os resultados indicaram que a produção do conhecimento sobre os temas Ă© transversal, se relacionando fortemente com outros tĂłpicos, como gestĂŁo estratĂ©gica, desempenho organizacional, gestĂŁo do conhecimento e orientação para o mercado (capacidade para inovar) e desempenho organizacional, gestĂŁo estratĂ©gica e valor (capacidades de TI). Ambos os temas sĂŁo recentes na literatura e o interesse dos pesquisadores está em franco crescimento. AlĂ©m disso, existem inĂşmeras oportunidades de pesquisa Ă disposição de futuros pesquisadores, tanto em relação a cada tema tomado de forma isolada, quanto combinados entre si.
Os conhecimentos reunidos na primeira etapa foram a base para a condução da segunda etapa, cuja abordagem, marcantemente empĂrica, buscou identificar a natureza das relações existentes entre os fenĂ´menos organizacionais centrais deste estudo (capacidade para inovar e capacidades de TI), associados a outros elementos pouco explorados na literatura, como a capacidade de reconfiguração de TI e o capital humano de TI. Para tanto, foram analisados os dados fornecidos por 258 instituições pĂşblicas brasileiras, de diversos segmentos, coletados por meio de survey conduzida com os mais altos gestores de tecnologia da informação. As análises foram realizadas por meio da aplicação de modelos de equações estruturais baseados em covariância (CB-SEM). De forma geral, os resultados indicaram que a capacidade de reconfiguração de TI deve ser elencada entre as capacidades de TI das organizações pĂşblicas, bem como que a capacidade para inovar e as capacidades de TI exercem um importante papel no desempenho dessas organizações. Os resultados indicaram ainda que o capital humano de TI Ă© um antecedente das capacidades organizacionais de TI. Por fim, os resultados indicaram que as capacidades de TI, por sua vez, exercem efeito positivo direto sobre o desempenho organizacional, bem como indireto, mediado pela capacidade para inovar.
O estudo contribui com a evolução da literatura das áreas de TI e inovação, na medida em que ajuda a preencher a lacuna da carĂŞncia de estudos que se utilizem de avançadas tĂ©cnicas quantitativas, de caráter bibliomĂ©trico, para analisar a produção cientĂfica de alto impacto disponĂvel. AlĂ©m disso, o estudo apresenta, de forma detalhada, todos os passos seguidos pelo trabalho, inclusive o uso combinado de ferramentas de análise, a fim de possibilitar a replicação por futuros pesquisadores. O estudo inova e contribui para o avanço da literatura das áreas de TI e inovação ao identificar que as capacidades de TI sĂŁo importantes antecedentes da capacidade organizacional para inovar, bem como o papel da capacidade de reconfiguração de TI e do capital humano de TI sobre as capacidades organizacionais de TI. Por fim, esta tese revela diversas oportunidades de pesquisa disponĂveis e recomendadas por diversas pesquisas de alto impacto recentemente produzidas.

Finalmente, os gestores sĂŁo apresentados a evidĂŞncias de que a criação de um ambiente favorável Ă inovação, e apoiado pela tecnologia da informação, Ă© um importante caminho para atingir melhores resultados organizacionais
Mapping the structure of science through clustering in citation networks : granularity, labeling and visualization
The science system is large, and millions of research publications are published each year.
Within the field of scientometrics, the features and characteristics of this system are studied
using quantitative methods. Research publications constitute a rich source of information
about the science system and a means to model and study science on a large scale. The
classification of research publications into fields is essential to answer many questions about
the features and characteristics of the science system.
Comprehensive, hierarchical, and detailed classifications of large sets of research publications
are not easy to obtain. A solution for this problem is to use network-based approaches to
cluster research publications based on their citation relations. Clustering approaches have
been applied to large sets of publications at the level of individual articles (in contrast to the
journal level) for about a decade. Such approaches are addressed in this thesis. I call the
resulting classifications “algorithmically constructed, publications-level classifications of
research publications” (ACPLCs).
The aim of the thesis is to improve interpretability and utility of ACPLCs. I focus on some
issues that hitherto have not received much attention in the previous literature: (1) Conceptual
framework. Such a framework is elaborated throughout the thesis. Using the social science
citation theory, I argue that citations contextualize and position publications in the science
system. Citations may therefore be used to identify research fields, defined as focus areas of
research at various granularity levels. (2) Granularity levels corresponding to conceptual
framework. In Articles I and II, a method is proposed on how to adjust the granularity of
ACPLCs in order to obtain clusters corresponding to research fields at two granularity levels:
topics and specialties. (3) Cluster labeling. Article III addresses labeling of clusters at
different semantic levels, from broad and large to narrow and small, and compares the use of
data from various bibliographic fields and different term weighting approaches. (4)
Visualization. The methods resulting from Articles I-III are applied in Article IV to obtain a
classification of about 19 million biomedical articles. I propose a visualization methodology
that provides overview of the classification, using clusters at coarse levels, as well as the
possibility to zoom into details, using clusters at a granular level.
In conclusion, I have improved interpretability and utility of ACPLCs by providing a
conceptual framework, adjusting granularity of clusters, labeling clusters and, finally, by
visualizing an ACPLC in a way that provides both overview and detail. I have demonstrated
how these methods can be applied to obtain ACPLCs that are useful to, for example, identify
and explore focus areas of research

Of tribes and totems: An author cocitation context analysis of Kurt Lewin’s influence in social science journals
This study used author cocitation context analysis (ACCA) to explore the intellectual structure of two Lewinian social science journal communities. ACCA is a variant of White’s (2000) ego-centered citation analysis, in which the focal author name serves as a filter. Articles citing Lewin between 1972 and 2001 in the Journal of Social Issues and Human Relations, sponsored by Lewinian specialties served as the test bed. Procedures conducted on cited author names—cluster analysis, multidimensional scaling, principal components analysis, and Pathfinder network analysis—generated coherent maps for each journal that maintained a “Lewinian” focus. The maps displayed the range of subject themes of interest to the specialties, which is consistent with Lewin’s importance to the specialties. Classifying all citations to Lewin as Totemic or Substantive assessed citation function. Results were convergent with the MDS maps in that Lewin’s work was used most frequently in a Substantive (central) way. Use of Lewin’s work did not conform to expectation in that the number of articles citing Lewin increased overall and the proportion of Totemic (peripheral) citations did not increase over the time studied. Analysis of Lewin’s works and concepts cited was also congruent with the specialties’ subject focus—JSI authors focused on social justice issues and HR authors used organization and small group research.Ph.D., Information Science -- Drexel University, 200
Challenges and trends in sustainable corporate finance: A bibliometric systematic review
Sustainable corporate finance is an attractive field of study in sustainability literature; however, the literature lacks systematic bibliometric analysis that provides a comprehensive review to clarify state-of-the-art sustainable corporate finance and that discusses new opportunities and potential instructions for further studies. To address this gap, this study adopts a literature review, bibliometric analysis, network analysis and co-wording technique to systematically investigate the Scopus database. In total, 30 keywords listed at least three times are used and are divided into six clusters considering six fields of research, namely, corporate finance in corporate sustainability, sustainable competitive advantages, sustainable stakeholder engagement, circular economy, sustainable corporate finance innovation and risk management and sustainable supply chain ethics. This study contributes to examining the sustainable corporate finance bibliometric status to provide directions for future studies and practical accomplishment. The sustainable corporate finance knowledge gaps are (1) corporate finance in sustainability; (2) sustainable competitive advantages; (3) sustainable stakeholder engagement; (4) circular economy; (5) sustainable corporate finance innovation and risk management; and (6) sustainable supply chain ethics. The knowledge gaps and future directions are also discussed
Study on open science: The general state of the play in Open Science principles and practices at European life sciences institutes
Nowadays, open science is a hot topic on all levels and also is one of the priorities of the European Research Area. Components that are commonly associated with open science are open access, open data, open methodology, open source, open peer review, open science policies and citizen science. Open science may a great potential to connect and influence the practices of researchers, funding institutions and the public. In this paper, we evaluate the level of openness based on public surveys at four European life sciences institute
