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
Profitability goals, control goals, and the R&D investment decisions of family and non-family firms
Full text linkR&D investments can help build sustainable competitive advantages and improve firm performance as well as foster industry transformations and economic growth. Nevertheless, managers also acknowledge the difficulties associated with managing R&D and the low chances of success of innovation programs. For this reason, researchers have long been interested in understanding how managers make R&D investment decisions and, more specifically, identifying the conditions under which managers are most likely to increase or decrease R&D investments. Research grounded in the behavioral theory of the firm suggests that a primary driver of R&D investment decisions is profitability: when profitability goals have not been met, managers are more likely to initiate a problemistic search through increasing R&D investments. While emphasizing profitability goals and their relationship with R&D investments, prior research largely downplays the role of goals beyond profitability that exist in a significant number of firms (family firms) that are owned and managed by family members whose primary concern is preserving their control over the organization. Research indicates that these family-centered non-economic goals lead family managers to minimize R&D investments and that the coexistence of multiple goals produces highly variable R&D investment behavior in family firms. Yet, how family-centered goals for control and profitability goals enter decision-making in family firms is not fully understood nor has any empirical study directly examined how these two apparently incompatible classes of goals jointly affect R&D investment variations in family firms. In this study, we propose that family managers form distinctive reference points that capture supplier bargaining power and are used to evaluate the degree of external obstruction to their managerial control. Accordingly, we hypothesize that family managers use reference points for profitability and for control jointly when making R&D investment decisions. The empirical analysis of panel data on 431 private Spanish manufacturing firms observed over the period 2000-2006 shows that the importance of profitability and control goals follows a sequential logic in family firms, such that family firms react more strongly to increasing supplier bargaining power when their profitability reference points have been reached. This study extends current understanding of the distinctive organizational processes engendered by family management in business organizations leading to new perspectives and research opportunities at the intersection of the innovation management and family business literatures
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

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
