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

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
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
The Psychic Distance Postulate Revised: From Market Selection to Speed of Market Penetration
Full text linkIn this paper we revise the psychic distance postulate of the Uppsala Model (Johanson and Vahlne, 1977, 1990) by injecting more recent findings (i.e., distinguishing between selection of foreign markets and time needed to achieve sufficient penetration in foreign markets and the role of social capital). The model we propose posits that a higher psychic distance decreases the speed of market penetration. On distant markets, internationalizing technology-based ventures need more time to establish a position in the foreign network and to obtaining positive cash flow. Our model presents social capital as a mean to overcome the psychic distance and to increase the speed of market penetration. We build our model on four case studies on technology-based new ventures internationalizing at very early age
Variación en el nivel de actividad a través de las etapas de iniciación empresarial. evidencia de 35 países
No full textAlrich and Martínez (2001) pointed out that in “entrepreneurship many are called, but few are chosen”. Many entrepreneurs try seriously to create a lasting organization, but most of them do not pass through the three stages of the entrepreneurial startup process. There is scarce research exploring the entrepreneurial startup process, particularly studying across countries the prevalence of individuals in the different stages. This paper uses data collected across 35 countries participating in the 2005 Global Entrepreneurship Monitor (GEM) study and we examine whether individual-level factors and national culture are related to the ratio of nascent entrepreneurs to potential entrepreneurs, and to the ratio of baby business owners to potential entrepreneurs. Our results show that there is significant variation across countries in how many individuals are active in the different stages of the entrepreneurial startup process. Our results also indicate that gender and age are related to a high ratio of nascent entrepreneurs to potential entrepreneurs.Alrich y Martínez (2001) señalan que “a emprender muchos son llamados, pero pocos son elegidos”. Muchos emprendedores intentan crear organizaciones que perduren, pero la mayoría de ellos no logran superar las tres etapas del proceso emprendedor. Existe muy poca investigación que examina el éxito del proceso emprendedor, sobre todo estudios que midan estas variaciones entre las etapas y que compararen entre distintos países. Este trabajo utiliza los datos de 35 países que participan en el Global Entrepreneurship Monitor (GEM) del año 2005 y examinamos los factores tanto individuales como de la cultura nacional que están relacionados con los ratios entre los emprendedores potenciales y los nacientes y entre los potenciales y los nuevos empresarios. Nuestros resultados muestran que hay variaciones significativas entre las fases iniciales del proceso emprendedor y los países. Nuestros resultados indican que el género y la edad son variables explicativas, sobre todo para la primera transición de potencial a emprendedor naciente
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
