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
Young people and housing transitions: moral obligations of intergenerational support in an Italian working classes context
No full textIn the last years, it is well established that young people rely on families more than ever, particularly in countries with a familialistic welfare state - such as Italy- where families play the main role in providing care and support to its members throughout the whole life course (Saraceno 2003).
In a context of worsening global economic crisis and increasing cut in welfare expenses, the role of parents and grandparents is one of fundamental importance in supporting young adults housing transitions (which suffer from the structural lack of adequate public policies), through both intergenerational transmission of wealth and informal support (Poggio 2012, Filandri & Bertolini 2016).
Recent studies focused on different kind of support and practices of negotiations within families with different socio-economical backgrounds, yet just a few research overtly take into account less advantaged contexts, such as working classes contexts (Holdsworth 2004; Brannen 2006; Helderman & Mulder 2007). The concept of ‘working classes’ will be here used critically, as an analytical tool to approach the empirical study of a social reality where processes of class dis-identification are at work (Irwin 2015), investigating how structural constraints influence the individual experiences of social locations.
The chapter moves from a retrospective longitudinal qualitative research carried out in Bologna (North Italy) in 2013-2014. Interviewing both young adults and their parents allowed us to enter the ‘black box’ of working classes families’ attitudes and practices, and better understand individual and structural factors affecting young people housing options. It aims to analyze how working classes mobilise their (relatively few) resources (economic, cultural and social capital), managing to support their adult children’ transitions towards independent living in a context of economic downturn and welfare retrenchment, and how different types of support are represented and negotiate by parents and children
Nannofossil and ammonite asssemblages, stable isotope stratigraphy, and the palaeoceanography of the Umbria-Marche basin during the Sinemurian-Pliensbachian (Lower Jurassic)
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
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
