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
Scaling the Aircrew Risk-Taking Behavior in Aviation Accidents: The Moderating Role of Phase of Flight
No full textVariations 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
Open innovation ecosystems: a mixed methods study on the strategic management of inter-organisational openness
No full textInter-firm trust and openness have been the subject of considerable attention in business innovation research. However, the strategic role of trust-based openness in innovation ecosystems is not as well understood. Moreover, while the concept of open innovation ecosystems is the mantra of contemporary innovation research, no-one has attempted to develop a validated measurement model for this construct. Finally, while debate continues about inter-firm collaborations and participatory modes of innovation, business strategy researchers have focused almost exclusively on the competitive advantage resulting from a firm’s inflow openness, i.e., obtaining and controlling valuable resources. A firm’s outflow openness strategy is rarely reflected on. To address these issues, this mixed methods research (conducted in Australia and USA) presents four analyses regarding (1) the role of trust-based openness in a firm’s ecosystem strategy, (2) the process of inter-firm trust-based openness in innovation, (3) the measurement of open innovation ecosystems, and (4) the competitive advantage of interdependent firms in open innovation ecosystems.
This dissertation synthesises resource dependence theory, social exchange theory, and the resource-based view. It first develops a conceptual model for strategising in ecosystems from a systematic review of relevant literature. Then, using the grounded theory method, it conducts three rounds of 54 interviews with senior managers in Macquarie Business Park, Australia, to theorise the process of inter-firm openness. A new scale is developed and validated against four survey samples of managers, two from Silicon Valley, USA (n=370; 412), and two from Macquarie Business Park, Australia (n=205; 424). Finally, the theorised model is empirically tested in two countries using hierarchical multiple regression and structural equation modelling. Results reveal (1) a significant role for trust-based openness in a firm’s ecosystem strategy, (2) four overarching dimensions of inter-firm openness which, occurring in chronological order – realisation, socialisation, strategic alignment, and two-way openness –explain how firms systematically adopt openness and migrate from traditional Egosystems to open innovation ecosystems, (3) the newly developed five-dimensional open innovation ecosystem-scale replicated across samples and exhibited strong psychometric properties, and (4) a firm’s outflow openness (i.e., allowing resource outflows) represents a gainful strategy of resource-building and of shaping innovation advantages in ecosystems.
The thesis contributes to the existing body of knowledge in four ways. First, it extends the traditional two-dimensional (cognition and action) strategy formulation model by integrating the neglected third relational dimension. Second, it develops a theory of inter-firm, trust-based openness in innovation. Third, it develops and validates a scale for measuring an open innovation ecosystem, which is the first measurement model of this construct. Last, contrary to the traditional wisdom, it demonstrates that allowing resource outflows even at a lower price (to benefit ecosystem partners) can positively impact a firm’s competitive advantage in ecosystems. The thesis refines and extends the scope and application of the resource-based view to open innovation ecologies. Implications of the findings are discussed and directions for future research are recommended.</p
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
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
