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
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
A new era in retail: Private-label production by national-brand manufacturers and premium-quality private labels
Full text linkPrivate labels have witnessed considerable growth in grocery retailing. While existing academic studies have provided valuable insights concerning the evolution of private labels, several issues remain largely unexplored. First, in the face of these large private-label volumes, private-label production opportunities arise. Due to increased private-label competition, national-brand manufacturers increasingly pursue a dual-branding strategy and engage in private-label production next to their national-brand activities. In chapter two of this dissertation, a major motivation for national-brand manufacturers to engage in private-label production, namely whether it creates retailer goodwill, is investigated. It shows that private-label production is indeed rewarded: national-brand manufacturers involved in private-label production for a discounter have a higher likelihood of obtaining national-brand shelf presence at that discounter. The third chapter focuses on one of the main reasons why retailers push private labels, i.e. because they generate high margins, and considers how a retailer’s private-label margins vary within categories. It demonstrates that a retailer’s private-label margins depend on the nature of the private-label supplier-retailer relationship, that they differ across quality tiers and package sizes, and that they are affected by a supplier’s extent of national-brand focus next to its private-label production for the retailer. Finally, this dissertation concentrates on the recent premium private-label trend. Even though premium private labels are seen as “one of the hottest trends in retailing,” retailers are selective in picking their battles with top-quality national brands and do not feel the need to extend their standard private label with a premium private label in every category. The fourth chapter provides insight into why retailers offer premium private labels in some categories, but not in others. The research presented in this dissertation is among the first to empirically investigate the phenomenon of private-label production, and to shed light on the recent trend of premium private labels
A new perspective on punishments and rewards in marketing channel relationships
Full text linkHow effective are punishments and rewards in influencing dealer performance in marketing channel relationships? Although often used in managerial practice, academic research on the relationship between punishment/reward and dealer performance has been scarce and demonstrates variable results. The aim of this dissertation is to resolve the indistinctness that currently surrounds academic research on the use of punishments and rewards in marketing channel relationships. The three studies in this dissertation advance current knowledge on this important topic. Results show that rewards and punishments are able to effectively increase dealer performance, when performance-contingent rewards are used, and when the broader network context, in which punishments are administered, is taken into account. These results have important management implications and several guidelines are suggested
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
Crossing boundaries: Involving external parties in innovation
Full text linkTo improve the return on investments in innovation, firms increasingly open up their new product development (NPD) processes by inviting external parties to participate. This dissertation focuses on the involvement of three different types of external parties in the NPD process: suppliers, customers, and the ‘crowd’. In the second chapter, a meta-analysis of the extant literature on supplier and customer involvement in NPD is presented. It investigates the antecedents and consequences of supplier and customer involvement in NPD. The third chapter focuses on customer participation in outsourced NPD. It shows how multiplex relationships that can cause role synergy, role conflict, and role ambiguity, moderate the effect of customer participation on the task performance of the developing firm. The fourth chapter deals with online idea generation contests in which ideas are crowdsourced in competitive settings. It provides insights into the prize structure that best stimulates the crowd to deliver creative ideas. Collectively, the research presented in this dissertation sheds light on how to successfully manage the participation of external parties in NPD, a timely managerial issue
