Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Risk Determinants and Investment Decisions: An Explanatory Study
Get PDFThis research suggest a general framework to help understating Jordanian investors’ disposition towards risk orientation, where risk attributes is a fundamental issue in creating monetary choices. This research examines various financial risk tolerance and investment orientation of investors in Jordan, where this study investigate whether demographic factors influence the financial risk tolerance and investment orientations. The research utilizes a randomly selected sample of 106 individual investors trading in the financial market of Jordan. The findings of the statistical analysis has confirmed that a high average risk orientation is related with higher income level and higher education level. The empirical investigation have had revealed that the demographic variables that have a substantial influence on investor’s risk orientations are income level, Age, and education level. Keywords: Risk attributes, financial decisions, investment choices, path analysis, PLS methods
An integration of information technology, culture of knowledge transfer and innovative work environment in support of organisationsal knowledge creation activities
No full textKnowledge management and knowledge creation is recognized to be of supreme
importance to the competitive advantage of organisations as well as a major agent of
change in the new era of the knowledge economy. This study empirically examines
knowledge creation activities in the context of the banking industry. It extends the
work of Nonaka and Takeuchi (1995) and others on the theory of organisation
knowledge creation by introducing the information technology infrastructure as an
enabler of knowledge creation condition (ITISKCFs), accompanied by the culture and
infrastructure of knowledge transfer. The research questions asked are: 'What are the
characteristics of an IT infrastructure that enhance the knowledge enabling conditions,
whether IT infrastructure capability can be define for knowledge creation? and 'What
are the shared effects of the culture (CKT) and the infrastructure of knowledge
transfer (IKT) when combined with IT infrastructure on knowledge creation
activities?' A positivistic approach is adapted using quantitative data. A survey
aimed at the middle managers of the financial services industry population was
conducted in an effort to investigate the knowledge creation activities and to examine
the relationship of knowledge enabling factors to the time spent on knowledge
creation activities. Theoretical developments on organisational knowledge creation
and knowledge enablers are presented and discussed. A conceptual framework is
developed based on the theory and hypotheses which were generated. Variables of
the research model are operationalised using confirmatory factor analysis (CFA) and
the data are analysed using structural equation modelling (SEM). The results of the
data analysis suggested that ITISKCFs support the activities of tacit to tacit, explicit
to tacit and explicit to explicit knowledge transfer, thus leading to the creation
sympathised, systemic and operational knowledge. While ITISKCFs fail to support
the activities of tacit to explicit transfer and, hence, failing to support the creation of
conceptual knowledge. CKT is a significant enabler of the activities aimed at explicit
to explicit and explicit to tacit knowledge transfer. IKT have failed to support the
activity of tacit to tacit, tacit to explicit transfer, and only one element of IIKT (IIKTK&
S) was a significant enabler of explicit to tacit, thus unable to support the creation
of sympathised, conceptual knowledge and partially supported operational
knowledge. While CKT fail to support the tacit to tacit transfer and, hence, the
creation of sympathised knowledge, it was the only enabler of the conceptual
knowledge; however, the statistical test suggested a significant but weak relationship
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
