Consumer acceptance and use of information technology: A meta-analytic evaluation of UTAUT2

Tamilmani, Kuttimani, Rana, Nripendra P., Dwivedi, Y.K. 15 March 2020 (has links)
Yes / Despite being regarded as the most comprehensive theory in understanding individual technology adoption – UTAUT2 theory with growing number of citations and impetus beyond IS domain face strong criticism on usage of the model in its entirety. This study located UTAUT2 based empirical studies in the Scopus and Web of Science bibliographic database through citied reference search in order to evaluate appropriate usage of UTAUT2 constructs. The meta-analysis results spanning across 60 studies with more than 122,000 cumulative observations found BI→UB as the strongest path with all significant values. PE→BI emerged as the most utilized path with most significant values underscoring the emphasis placed by consumers on utilitarian value. Meanwhile, with most non-significant path values the future usage of EE→BI path is been cautioned and questioned. Finally, trust, personal innovativeness, perceived risk, attitude, and self-efficacy were found as the five topmost UTAUT2 extensions.

Following the Footnotes : A Bibliometric Analysis of Citation Patterns in Literary Studies

Hammarfelt, Björn January 2012 (has links)
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>

The Relevance of Citations : a case of study of stratospheric ozone monitoring

Philipson, Joakim January 1996 (has links)
A contextual citation analysis was performed on a sample of 68 articles citing either or both oftwo key papers from the research field of stratospheric ozone monitoring.The theoretical approach of each article was assessed as either chemical or dynamical, or wasleft unspecified. Functions of citations to the two key papers were classified into 13 categories,seen to express various kinds of relevance relationships. Topical relatedness between citedand citing articles was studied in terms of number of shared descriptors and the union overlapmeasure. A certain theory~dependence, in the sense of a relatively high degree of correspondence between the theoretical approach of citing and cited articles, was observed in the material. The correlation between topical relatedness and citation relationships appeared to beweak.

From health research to clinical practice : understanding pathways that use journal articles and informing impact assessment

Jones, Teresa Helen January 2017 (has links)
For biomedical research to improve clinical practice, and for funding levels to be sustained, it is increasingly important to understand the pathways from research to clinical practice and to assess the societal impact of research. Approaches to research evaluation through traditional study of journals, journal articles and standard citation analysis, have played comparatively small roles in these developments. In this thesis I critically review how I applied existing methods, and developed a new approach, to study two pathways from research to clinical practice. For Pathway 1, questionnaire surveys of clinicians' views on journals read to inform their clinical practice, and comparisons with impact factors, revealed that a few journals were read widely and considered important by clinicians. Relationships between journal importance and impact factor were complex. For Pathway 2, I applied a novel methodology to identify important citations to four key research papers in an attempt to trace important citations through numerous citing generations. My findings included: few cited papers were important to the citing papers; the number of citation occasions within the citing paper correlated strongly with a cited paper's importance; self-citations were also important; and it was feasible to trace through a series of generations of citations. Evidence of societal impact of the four key research papers examined in my studies included important papers in subsequent generations cited in clinical guidelines, many of which were international. In assessing the impact of my own studies, I found Pathway 1 papers had societal impact on research evaluation methodology; journal editorial policy; and medical library provision policy and practice. Societal impacts of the new methodology, Pathway 2, included informing further methodological development and research evaluation. My portfolio, together with my critical review, adds understanding and provides additional data to current assessment methods of wider impacts of research, and bases for further studies.

O objetivo desta pesquisa é analisar as citações utilizadas na elaboração das teses defendidas de 1999 até 2007 no Programa de Pós-Graduação em Administração da Escola de Administração da Universidade Federal do Rio Grande do Sul, e, a partir das análises, obter indicadores de apoio à tomada de decisão no desenvolvimento de coleções da biblioteca. Para tal, analisam-se a tipologia dos materiais bibliográficos utilizados, a idade da literatura, os títulos de periódicos citados e a preferência do idioma dos materiais consultados. As informações obtidas permitirão otimizar a alocação de recursos para investimento em material informacional, traçar diretrizes para o armazenamento retrospectivo da coleção, determinar a composição da coleção-núcleo de periódicos, avaliar em quais idiomas devem ser selecionados os materiais bibliográficos em futuras aquisições, bem como preparar possíveis cortes na coleção devido a eventuais reduções no orçamento da biblioteca. / The aim of this research is analyze dissertations citations patterns uphold between 1999 and 2007 in the Programa de Pós-Graduação em Administração of Escola de Administração at Universidade Federal do Rio Grande do Sul, and built up indicators to support library`s collection development decision-making. In doing so, we analyzed the kind of bibliographic materials used, his age, the main journals, and the references language. The result allows optimize resources` allocation and investment in informational material, establish retrospective collection storage guidelines, determining the core collection journals composition, indicate what language bibliographical materials should be selected in future acquisitions, and prepare for collection cuts due to possible library budget reductions.

Specific research questions include: the number and research subjects of dissertations; the number, form types, content types, core journals, half-life, languages, publication locations, repositories of cited literature. The findings are as follows. The most productive institute for the research of the R.O.C. history was National Chengchi University. Dissertations guided by two or more advisors account for 17%. The majority of research subjects of dissertations were social, political and cultural. Furthermore, the majority of sub-subjects of social research dissertations were social movements and women. The average citations of single dissertation were 317. The most cited form type of citations was Books (62.56%), followed by continuous publications (18.62%), and unpublished papers or manuscripts (9.50%). The most cited content type of cited books was monograph (54.67%), followed by compilation of historical materials and records (9.54%), and biographical materials (6.79%). The core journals about the R.O.C. history research were difficult to observe, because of the diversity of research topics and that single journal may largely cited by single dissertation. The half-life of cited books was 20.4 years, cited continuous publications was 25.02 year, and cited newspapers was 64.3 years. The main language of cited literature was Chinese (88.76%), followed by English (7.41%), and Japanese (3.71%). The main publication locations of cited Books were Taiwan and Mainland China, together accounting for 85.01%. The main repository of cited unpublished manuscripts and records were Academia Historica, followed by Archives, Institute of Modern History, Academia Sinica, Kuomintang Party Records Archives, and Taiwan Historica. The suggestions of this study are as follows. Developing standard academic citation format in the field of history. Encouraging archives repositories to open manuscripts and records in multi-ways. Enhancing cooperation and resources integration of libraries and archives. Expanding the scope of citation analysis in the field of history. Investigating the behavior of historical researchers by qualitative research methods.

Conducting Online Research Undergraduate Preferences of Sources.

Rosalyn Metz 2006 April 1900 (has links)
When students write research papers they use a variety of sources in their paper. These sources range from web pages to research articles. The purpose of this study was to decide whether or not undergraduate students would choose to use scholarly or non-scholarly sources when presented with both types of sources in a set of search results. Twenty Duke University students were recruited for the study. They were given a research topic and asked to perform a search. Both the search results and interface were fabricated by the researcher in order to control the experimental environment. The students were asked to rate the sources found in the results, choose four sources to use for their research scenario, and finally, were asked to explain reasoning behind their choices. The findings concluded that the students in this study were more likely to choose scholarly sources over non-scholarly sources and give these scholarly sources higher ratings.

Building a Better Mousetrap: Capturing New Data in ISI Journal Citation Reports and Local Journal Utilization Reports to Support Academic Collection Managers

(E. Ashley Rogers Brown) 12 April 2006 (has links)
The ISI provides librarians with tools such as the Journal Citation Reports (JCR) and the institution specific Local Journal Utilization Report (LJUR) to aid in the management of serials collections. These tools enable librarians to respond quickly to changes in publishing practices and purchasing options. While available literature often criticizes ISI data, few studies provide concrete recommendations for improvement. This study explores two extensions to LJUR: (1) adding citation date and (2) creating institution specific impact factors. In addition, I explore the degree to which self-citations influence the ISI impact factor. Publication and citation calculations are made for three prominent southern universities’ research chemists using a corpus of full text articles drawn from 27 American Chemical Society (ACS) journals and stored in an Oracle database. The ACS research corpus impact factor simulation and ACS research corpus self-citation omission impact factor are also created and compared with current JCR data.
