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
Innovation and by-product valorization: A comparative analysis of the absorptive capacity of food processing firms
No full textThe transition toward the bioeconomy concerns how firms innovate, especially how they utilize bio-based resources. This qualitative study explores how incumbent firms in a low-tech industry like food make use of technological developments to create high added-value for their by-products. The paper compares managerial efforts to utilize biotechnology in a meat and a dairy firm in the Norwegian food processing industry. The theoretical approach draws on the concept of absorptive capacity from organizational learning literature and innovation studies. The study finds that firms in the same industry with quite similar structures (i.e. the form of ownership) can nevertheless pursue divergent strategies toward developing innovations for by-product utilization. Through the process of learning, the study notes the role of firms’ absorptive capacity—exploratory, transformative, and exploitative—in acquiring external knowledge, experimenting with the newly acquired knowledge, and mobilizing necessary resources to adopt and develop technological innovations during the transition process. The study highlights the importance of inter-industry learning and research collaboration, market understanding, and supportive policies and regulations in fostering a bioeconomy
Incumbents in the Transition Towards the Bioeconomy: The Role of Dynamic Capabilities and Innovation Strategies
No full textThis study explored incumbents’ roles in the transition towards the bioeconomy by examining what goes on inside firms, what strategies they practiced, and how these affected the way incumbents engaged in the transition, as well as their ability to innovate. The study focused on the Norwegian meat-processing sector, investigating how dynamic capabilities affected incumbent firms in the transition process, and the management strategies adopted in response to external pressures (local and global) and to innovation opportunities. The analytical approach builds on two theoretical pillars: Multi-level perspective and dynamic capabilities. The findings showed that the incumbent exercised different modes of behavior—first-into-niche and follow-into-niche—in response to innovation pathways during the transition, mobilizing various dynamic capabilities—learning, financing, and organizational restructuring. The study sheds light on the underlying business dynamics of incumbent firms within a given regime and on intra-regime dynamics concerning innovation opportunities, and notes the proactive roles of incumbents in the sustainability transition

The studies are carried out within a cross-disciplinary framework, drawing on a diverse set of theoretical approaches and defining different valorisation pathways.
Organic waste streams from households and industry are becoming a valuable resource in today’s economies. Substances that have long represented a cost to companies and a burden for society are now becoming an asset. Waste products, such as leftover food, forest residues and animal carcasses, can be turned into valuable products such as biomaterials, biochemicals and biopharmaceuticals. Exploiting these waste resources is challenging, however. It requires that companies develop new technologies and that public authorities introduce new regulation and governance models.
This book helps policy-makers govern and regulate bio-based industries, and helps industry actors to identify and exploit new opportunities in the circular bioeconomy. Moreover, it provides important insights for all students and scholars concerned with renewable energy, sustainable development and climate change.publishedVersio
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
