Innovation and Knowledge Transfer: the Role of Inventors’ Mobility and Collaboration Networks
No full textThis article studies the contribution of different channels of knowledge transfer on innovation output, measured by patent production. We deal with informal channels of knowledge transmission that arise from working relationships established by inventors, and study their impact on firm economic performance in terms of innovation production. The study’s contribution to the literature is twofold. First, differently from most of the existing literature on the topic, we consider those relationships not formally settled in co-inventorships. These relationships, although informal, can be responsible for the creation of networks of knowledge sharing and transfer (Almeida and Kogut, 1999; Power and Lundmark, 2004). Specifically, we consider those interactions that are born through inventor multi-collaborations and mobility. Second, rather than studying the relationship between social interactions and the diffusion of knowledge, we analyse their effect on company innovation production.
The analysis is carried out on the Italian region of Veneto. Resuming the debate on the localization of knowledge transfer and the existence of productivity lags, the paper focuses on the role played by geographical proximity, and on the dynamic effects of knowledge flows. The geographical issue is faced at a very detailed level; we measure knowledge spillovers observed within the same Local Labor System (LLS), between different LLSs of the region and, also, from extra-regional LLSs. The work is based upon the original OECD REGPAT database on patent applications filed at the European Patent Office. The dataset has been cleaned by using a manual procedure that allows to correctly identify inventors and applicants, to avoid false mobility and overestimation of knowledge connections. The estimates, exploiting the panel dimension of the dataset, show that inventor-firm networks and inventor mobility have highly localized effects on productivity. However, while the productivity effects induced by inventor mobility are almost simultaneous in time, the effect of inventor-firm networks is lagged in time
Productivity in Innovation: The Role of Inventor Relationships
No full textWe study the transmission of tacit knowledge arising from working relationships established by inventors and its impact on firms’ knowledge creation. First, we consider knowledge spillovers that originate through inventor working relationships that are not the result of collaboration agreements among patenting firms. Second, we analyse their effect on the creation of new knowledge as measured by companies’ patenting activity. The study focuses on the role played by geographical proximity. The analysis was carried out on the population of firms located in the Italian region of Veneto and is based upon the original OECD REGPAT database that records all patenting applications at EPO
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
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
