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
Work commitment and engagement in south Italian volunteers
No full textObjectives. Recent research on volunteering has increased its interest in integrating different theoretical models such as motivational and socio-psychological ones. The current research replicates and extends a Swiss survey (Guntert, 2008) among a sample of Italian volunteers. The aim was to examine the antecedents (mainly in terms of motivational factors and identification) of outcomes such as commitment and engagement towards volunteering. Methods. To examine these antecedents and the outcomes, a questionnaire was administered to a sample of 165 young Italian adults who were engaged in various voluntary associations in south Italy (Campania and Sicilia).
Results. Our analyses, underlining the peculiarity of voluntary work, shows significant relations between motivation factors, commitment and engagement; there was also some important difference between Swiss and Italian results, concerning motivational factors. Conclusion. The implications for organizational contexts in social work will be presented
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
A Time-Lagged Examination of the Greenhaus and Allen Work-Family Balance Model
No full textThe work-family interface is a compelling topic that calls into question labor market
dynamics and work processes, together with important social and family composition changes.
The present study aimed at examining the antecedents of Work-Family Balance (WFB) in Italy
consistent with Greenhaus and Allen’s (2011) conceptual model in which the characteristics of work
and family roles have an indirect impact on work-family balance through Work-Family Conflict
(WFC) and Work-Family Enrichment (WFE), and where job and family satisfaction are considered as
predictors of WFB. A total of 568 workers participated in a time-lagged correlational study, filling a
questionnaire. The theoretical model was tested by assessing the mediating role of job and family
satisfaction as well as related antecedents, conflict, and enrichment between the family and work
contexts, through Structural Equation Modeling (SEM). The results partially confirmed the theoretical
model: work-to-family enrichment and work-to-family conflict predicted family satisfaction, which
also mediated their association with WFB. The results in the family-to-work direction did not support
the initial research hypotheses. The hypotheses about associations between demands and resources,
conflict and enrichment in both directions, and of the moderating role of core self-evaluations were
partially confirmed. The results highlighted that organizations need to carry out periodic assessments
of WFC and WFE, in order to provide benefits and resources, to reduce conflict, and increase
enrichment, through proper interventions (training activities, professional development, mentoring,
and forms of flexibility)

To Be or Not to Be Temp? An Analysis of the Moderating Role of Motives for Accepting Temporary Employment
No full textWe investigate the role of contract volition and motives for accepting temporary employment in the relationship between precariousness of life and negative psychological symptoms in a sample of 275 Italian temps. Results suggest that the negative effect of contract volition on negative psychological symptoms is partially mediated by precariousness of life. A moderated mediation model shows that specific motives moderate the negative effects of contract volition on precariousness of life, so that when contract volition is higher, workers with weaker motives feel less precarious. This study broadens our understanding of temporary employment outcomes by showing that the negative consequences of precariousness of life seem to be less troublesome among temporary workers with higher contract volition and lower motivation
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
