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
Domain design principles for managing complexity in conceptual modeling
Get PDFComplexity is a problem that can be found in many aspects of research that deals with design. In particular, complexity is found in various business processes that must be modeled and represented in a meaningful way. One of the ways to address complexity is by using decomposition, for which a number of decomposition principles have been proposed. However, there are two domain specific areas in which these principles are lacking: the scope and the context of the problem. This research addresses this problem by deriving two new principles for managing complexity, and evaluates the proposed principles through an example case to illustrate their potential use
The paradigm of design science research: a tool-supported literature review
Get PDFIn this paper, a review of the state of the art of theory associated with the young and quickly evolving Design Science Research (DSR) paradigm is presented. The core of the review consists of a structured literature search covering the senior scholars’ basket of eight from 1977 until the end of 2016, which resulted in data set of 196 sources. An iterative, selective coding of the title and abstracts revealed four major grounded clusters (138 papers). Three clusters (93 papers) were selected for co-citation analysis and augmented with additional forward and backward searches. The co-citation analysis affords an objective look at the current state of theory use in DSR and allows for the systematic identification of research opportunities. Altogether, the paper presents a multi-grounded DSR approach to literature reviews and contributes a reliable platform for further analysis and development of the DSR paradigm
Where is the crowd?
Get PDFCrowdfunding has received increasing attention in the financial services space in the past few years. This is because crowdfunding has become a viable alternative to traditional capital investment and thus a threat to investors in that sector. Various platforms exist which allow fundraisers to pitch an idea and spread awareness with the intention of acquiring backers. Most backers of crowdfunding campaigns come to the platform with the fundraiser rather than from the platform itself [25]. Fundraisers must find and engage a crowd and not rely on the platform for provision of the crowd. This paper sets out four action design principles for identifying and engaging a crowd. Using a boundary object theory approach, the crowdfunding campaign is broken down based on backer’s social worlds which define the crowd and their interests
