Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
A framework for understanding the benefits of supply chain management systems
Full text linkOrganizations invest heavily in Supply Chain Management (SCM) systems expecting benefits stated by software vendors and implementation partners. However, both academic and industry reports suggest that there are growing challenges in realizing the benefits of SCM applications, preventing the success of SCM projects. Although there exist well-publicized research on Enterprise Resource Planning systems benefits and Customer Relationship Management systems benefits, there is a dearth of research on studies evaluating SCM systems benefits from a holistic perspective. In order to better understand the benefits of SCM systems, this study proposes a SCM system benefit framework. The preliminary framework is derived from content analysis through 21 academic studies and 20 vendor success stories. This preliminary framework consists of 3 dimensions - Strategic, Managerial and Operational and 21 indicators. Subsequently, the benefits in the preliminary framework were validated in a large fast moving consumer goods (FMCG) manufacturer. The results reveal that around ninety percent of the claimed benefits from literature and vendor success stories have been confirmed. It is also noted that the unconfirmed benefits cannot be realized in a short time due to certain constrains. This validated SCM system benefit framework has substantial implications for research and practice
Reconceptualizing system use for contemporary information systems
Full text linkSystem use is a centrally important construct in a plethora of research. Yet for all its importance, and still consistent with observations of DeLone and McLean (1992), system use suffers from a “too simplistic definition”. Much of prior conceptualizations of use have been idiosyncratic and unsystematic. This study examines contemporary systems use and thereafter, introduces a framework for selecting system use constructs and measures based on three critical considerations: typology of the system-in-use, level of process automation, and system lifecycle. Measures are then recommended for system typologies under three types of system use: frequency, depth and explorative use. Our empirical investigation validates the framework using data from operational users of an archetype of contemporary systems- Enterprise System. Analysis of six PLS models: identify system use as an antecedent of individual-impacts, confirm the importance of depth of use, role of explorative use at early stages of a lifecycle, and alludes to issues in employing popular frequency based use measures. The study advocates several insights towards a deeper understanding of contemporary systems use. Nonetheless, future research can be directed towards a larger quantitative study to facilitate a broader theoretical and empirical treatment, and a consolidated set of prescriptive actions for practitioners
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
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
