Searching for knowledge in response to proximate and remote problem sources: Evidence from the U.S. renewable electricity industry
No full textResearch Summary We consider how different problem sources-proximate versus remote-relate to heterogeneity in search breadth. While studies of search have established the importance of search breadth, and argued that problems trigger search, they have focused on a single problem source instigating search. We extend prior research by considering how search breadth differs in the presence of proximate and remote problem sources. Because of differences in familiarity with each type of problem, and in expectations of their ability to influence the problem source, problems triggered by remote sources associate with greater breadth. Firms' technological capabilities, meanwhile, temper these findings; capable firms exhibit broader search when facing problems raised by proximate sources. Using data describing the U.S. renewable electricity sector, we generate theoretical and empirical implications.Managerial Summary When facing new problems, firms tend to seek knowledge from various sources to understand the problem better and identify relevant solutions. The source of the problem may be an essential trigger to the breadth of search activities, particularly whether the source is proximate or remote. To test this notion, we compare U.S. utility firms' search breadth when facing regulations emphasizing increased renewable generation from both the federal and the state governments. We find that firms tend to search for knowledge about renewable technologies more broadly following federal regulatory actions. However, firms that have previously generated renewable electricity search more broadly following state regulatory actions. By exploring firms' choices in the U.S. renewable electricity sector, our research generates important managerial and public policy implications
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
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
How open systems intermediaries address institutional failures: the case of business incubators in emerging-market countries
No full textIn emerging-market countries, commercial institutions do not always develop quickly or effectively to support ambitious entrepreneurs. How do intermediaries remedy these problems? We address this question by drawing on institutional literatures to develop the concept of open system intermediaries (OSIs). Our research design involves examining business incubators in emerging markets as a form of OSI. Empirically, we examine the relative emphasis that business incubators in emerging-market countries place on developing markets versus developing specific businesses. The study further examines how private, government, academic, and NGO sponsorship of incubators influences the mix of services that incubators provide. In sum, this work contributes to our understanding of how, why, and when intermediaries emerge to address institutional failures
