Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Do flexible employment contracts change household income differences in Italy?
This paper examines whether the growing use of non-permanent
contracts may have in uenced the intra-family income differences in Italy over time. After the 1996, a number of reforms were implemented to reduce the levels of employment protection. Thus we aim at providing evidence on the determinants of potential changes to personal level of income before and after the introduction of such rules.
In particular, we calculate the contribution of each individual within the family using two Italian longitudinal data (namely ECHP and IT-Silc). We perform estimations for men and women, separately. Our results conrm that the amount of contribution changes over the span considered. Fathers are generally more likely to support other family members. Sons are instead money receivers, and the magnitude of the coefficient is especially large when labour market exibility has been
already introduced. Individuals with part time temporary contracts face less favourable financial conditions. Finally, those who are out of the labour market (i.e. retired, unemployed, inactive) contribute negatively within the family
Income inequality among family members in Italy: who gains and who loses?
This paper looks at income inequality in Italy amongst the various components of the family. Employing the OECD procedure (OECD 2010) we calculate individual monetary contributions, based on the 2010 Italian Statistics on Income Living Conditions (IT-Silc) survey questionnaire. We define our indicator as the difference between the personal and per-capita income divided by the equivalent family income. Assuming that family members act as an income-equalising institution, regressions are run on the entire sample and on the sample split by gender; specifications include personal and family characteristics to capture their effects on reducing income inequality amongst family components. The estimates show that monetary contributions vary by gender. More educated women are more likely to be able to equalise consumption among family components, while for men, education is not significant once economic activities are controlled for. Predicted values recognise males as the primary breadwinners and underscore that men and women behave differently based on age
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
Bargaining or Efficiency within the Household? The Case of Italy
Two aspects play a role in the household decision-making, the efficiency and the bargaining power’s argument. The crucial difference between the two approaches is the expected influence of personal and partners’ wage. To investigate which of the two models hold, in the Italian context, we estimate an ordered probit model for four aspects of household decision-making. We use It-Silc 2010 as it provides a module on intra-household sharing of resources. Results show that in strategic control decisions, where the power argument should dominate the efficiency approach (i.e. decisions on durable goods, savings and other important decisions) the spouse/partner with higher wage is the household decision maker. For decision regarding executive management (i.e. decision on everyday shopping) the efficiency argument holds.

Dispelling the Myths Behind First-author Citation Counts
We 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
