Wine clusters and leading firms in Tuscany
No full textBased on the case study research methodology, the chapter illustrates the results of a study aimed at investigating entepreneurship in the Tuscan wine business. Within the regional scenario, we can observe different areas characterized by peculiar territorial and structural traits creating multiple production systems that seem populated by diverse entrepreneurial actors. Different entrepreneurial models will increase the complexity of the regional scenario, enriching the territory with resources and knowledge and creating the opportunity of exchange and innovation processes.
Three different entrepreneurial actors are identified: Traditional entrepreneurial models – characterize the micro and small local enterprises of “follower” kind, with competencies mainly concentrated on production and – basically – adaptive strategies. These (usually) smaller producers, are not able to accomplish effective marketing strategies or to start innovation processes on their own, showing imitative behaviors and benefiting from the positive consequences “absorbed and released” by the local system thanks to the winning performance achieved by other wineries .
In transition local familiar models – local enterprises that, even respecting traditions, have been able to introduce elements of newness in the business management, inserting new managerial roles next to the historical family or new competencies through the cooperation of external individuals. Most of these actors are the ancient nobility that have transformed part of the latifundium into vineyards.
Hexogenous entrepreneurial models - result of a massive increase of investments on the part of entrepreneurs coming from inside and outside the region, already working in the wine business or in other sectors
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
