Why not take a performative approach to entrepreneurship?
No full textAmong entrepreneurship researchers, there has been growing attention to questions of ontology, epistemology, and axiology. Recently, Packard (2017) advocated an interpretivist approach to entrepreneurship. In this paper, we articulate a performative approach, which offers a far more distributed and emergent view of entrepreneurship as process. In addition to briefly introducing some of the intellectual traditions underlying a performative approach, we highlight important differences between interpretivism and performativity and summarize the implications of taking a performative approach to entrepreneurship
Technological exaptation: A narrative approach
No full textWhat do the feathers on a bird have in common with the glass in fiber optics? The answer lies in exaptation, a concept that has been creatively repurposed (i.e., exapted) from evolutionary biology to the field of technological innovation. Inspired by this movement, we examine different kinds of biological exaptations and draw analogical links to different kinds of technological exaptations. Going beyond mere analogies, we consider a narrative approach to inducing technological exaptations
Contextualizing entrepreneurial innovation: A narrative perspective
No full textWe review literatures that inform entrepreneurial innovation, paying particular attention to different conceptualizations of contexts. Early research explored micro and macro approaches with some scholars taking an actor-centric perspective and others a context-centric perspective. Bridging these perspectives, different scholars proposed multilevel approaches, arguing that opportunities are "found" or "made" by entrepreneurs whose efforts are moderated by contexts. More recent constitutive approaches, such as those informed by structuration, complexity and disequilibrium theories, have viewed entrepreneurial innovation as a process wherein actors and contexts are co-created. We add to constitutive approaches by examining how entrepreneurs contextualize innovation through narratives. A narrative perspective considers entrepreneurial innovation as an ongoing process involving embedded actors who contextualize innovation through performative efforts. We discuss the implications of this perspective for policy, entrepreneurs, and research. (C) 2014 Elsevier B.V. All rights reserved
Serendipity arrangements for exapting science-based innovations
No full textExtant literature draws attention to the importance of science-push, demand-pull, and institutional-steering as mechanisms driving science-based innovations. We contribute to this literature by highlighting exaptation, which refers to the cooptation of existing traits for new functions. When applied to science-based innovations, exaptation refers to the emergence of functionalities for scientific discoveries that were unanticipated ex ante. We explore how exaptation can be induced through narrative properties (relationality, temporality, and performativity), and how serendipity arrangements such as exaptive pools, exaptive events, and exaptive forums can be structured to maintain, activate and contextualize scientific discoveries. We close the paper by discussing the implications of exaptation for academia, industry, and policy
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
