The Evolution of Resources in Research-Based Spinoffs: Learning from a Case Study
No full textA great deal of interest and concern has been raised in recent years over the theme of research‐based spinoffs
(RBSOs) and their economic and social implications. An RBSO is a new business entity formed to market one or more
related technologies generated from the research work of a public research institute. The literature has studied this
phenomenon from three different theoretical perspectives: resource‐based, business model and institutional (Mustar et al.
2006), but no studies have integrated the above three theoretical perspectives. Other gaps identified in the literature are
the lack of an analytical consideration of the impact of technological resources on RBSO performances and the limited
empirical studies on the evolution over time of RBSOs, i.e. considering the resources in the different stages (or phases) of
the RBSOs’ development. The aim of this paper is to evaluate the evolution of a spinoff’s resources and institutional
linkages over time, adopting the four stages of spinoff development identified by Djokovic and Souitaris (2008): 1)
opportunity recognition, 2) entrepreneurial commitment, 3) threshold of credibility and 4) threshold of sustainability. To
this extent, the authors have extensively investigated a research‐based spinoff from the Italian ICT sector .This paper
provides a thorough and integrated analysis of the research‐based spinoff in terms of resources (including institutional
resources), using a longitudinal approach, and highlights the importance of resources during its life‐cycle
Space technology transfer: a systematic literature review
No full textTechnology transfer has been shown to stimulate innovation in business and commerce, support economic
growth and provide a return on public investment in R&D. This is particularly true for space technologies characterized by a
very high innovative value and production in small quantities. The aim of this paper is to systematically review the space
technology transfer literature and to suggest directions for future research. The transfer of space technology has been
studied by academic researchers, managers of space agencies and government ministry officials. The range of studies calls
for a systematic review of the literature aimed at synthesizing the findings from individual studies or reports in an unbiased
manner, so as to present a balanced and impartial summary and to interpret the findings in a way that highlights the
research gaps in this important field of research. This paper presents an overview of the dominant thinking (made explicit
in the selected articles) from the 1995 until today, indicating problems of analysis, research gaps and a future research
agenda
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
