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
An Experimental, Tool-Based Evaluation and Requirements Prioritization Techniques in Distributed Settings
Get PDFIn this paper, we compare and analyze three common techniques for prioritizing software requirements: Analytic Hierarchy Process (AHP), Cumulative Voting (CV) and Likert Scale Technique (LST). These techniques are based on a ratio scale and are applied within this research as part of a hierarchical approach to requirements analysis on different levels of abstraction. For the systematic evaluation of these techniques in distributed settings, a controlled experimental setting was developed and carried out via the Internet. Therefore, a particular Web application was developed and data from 199 subjects was collected. The overall results indicate that LST is a simple, fast, and well-scaling prioritization technique, whereas slightly less precise than the other two techniques. However if accuracy is an important criterion, and a more complicated and slower technique is accepted, CV has proven to be most adequate. For the AHP, particularly when used with many requirements, a recommendation cannot be given because of poor scalability
Tight versus Loose Organizational Coupling within Inter-Firm Networks in the Enterprise Software Industry

Get PDFResearch on mobile technologies has received an increasing attention. However, most of the existing literature focuses on the use of mobile technologies on a managerial level, with technology as an enabler for information and communication exchange. The impact potential and their corresponding functionalities at the operational level have not yet been analyzed. This study addresses this gap. The key objective is the development of a conceptual model to explain how mobile technologies impact business processes in the construction industry on the operational level. Thus, a generic model will be developed on the basis of existing literature, especially the concept of Task-Technology-Fit. It emphasizes how task complexity affects the required effort of individual information access, information capturing as well as the timeliness of information. Then, it will be deduced how mobile technologies affect the forces and relationships in this model. The evaluation of the model shows that there is a strong influence of the reduced effort for accessing information on the process performance if there is a high task complexity. In addition to the new level of analysis (the system user is a worker instead of a manager), a new method of performing the model evaluation is utilized. For this evaluation, a 3D-laboratory experiment is combined with a computer simulation
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
Harnessing Diversity: Individual Differences in the Use of Farm Management Software
Get PDFThis paper reports on an interpretive study which explores the influences of socio-cultural factors in the interplay between farm women and technology for farm management purposes on Australian family cotton farms. The study revealed growing support for the theory of individual differences of gender and IT in situations where women and men farm partners perform certain tasks for which they are neither biologically predetermined nor socially constituted. By harnessing the diverse skills of farm partners, decision making on the family farm is enhanced. This paper contributes to both theory and practice by extending the conceptual foundations for recognising and valuing gendered relationships and diversity in a global context.Griffith Business School, Dept of Employment Relations and Human ResourcesNo Full Tex
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
