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

No full textAppropriate 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
The Impact of Government Procurement Composition on Private R&D Activities
Full text linkThis paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving innovation that incorporates industries with heterogeneous innovation sizes. Government demand in high-tech industries increases the market size in these industries and, with it, the incentives for private firms to invest in R&D. At the economy-wide level, the additional R&D induced in high-tech industries outweighs the R&D foregone in all remaining industries. The implications of the model are empirically tested using a unique data set that includes federal procurement in U.S. states. We find evidence that a shift in the composition of government purchases toward high-tech industries indeed stimulates privately funded company R&D.public demand, technological change, endogenous growth
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
The Role of Regional Knowledge for Innovation
Full text linkThere is a broad consent that the extent, quality as well as the success of innovation activity is critically dependent on the generation and the application of knowledge. It is also widely recognized that innovation processes have a pronounced regional dimension and that the conditions for innovation activity may differ considerably between geographic areas. We investigate the contribution of different inputs, particularly different knowledge sources, on regional patenting output in the framework of a knowledge production function. Earlier work (Fritsch & Franke, 2004) suggests that there are considerable differences with regard to the role of different types of knowledge for innovation activity. These different types of knowledge have different degrees of localization. We expect that the impact of the knowledge sources differs by field of as well as according to the type of institution (university vs. non-university public research institution). .One may, therefore, expects that the technology opportunity differs across sectors and geographical areas. However, little is known about such differences. The innovation indicator used in our analysis is the number of patents. The knowledge sources included are: •R&D employment, •R&D employment in small firms and large firms respectively, •Qualification of the regional workforce, •Qualification of employees in small firms and large firms respectively, •Size (number of employees, budget) of public research institutions by field of research. •Amount of research funds from private firms by field of study. •Amount of external research funds from public departments by field of study. •Amount of external research funds from the German Science Foundation (DFG) by field of study. The contribution of these knowledge sources is tested systematically on the level of German districts (Kreise). Information on the different knowledge sources is available for each district on a yearly basis. We test the influence of the knowledge sources in different specifications by including the respective information for the particular region and for adjacent regions. This will reveal the role of local knowledge and of interregional knowledge spillovers for innovation behavior. We expect that technology performance of regions is a path dependent process. The analysis is performed for German regions in the 1990s. Information on the yearly number of patents relates to the years 1995-2000. regional employment is taken from the German Social Insurance Statistics. Information on universities and their funds are taken from the German Hochschulstatistik which has been especially prepared for this analysis.
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
