Famiglie che cambiano
No full textLe trasformazioni demografiche e sociali intervenute negli ultimi decenni nel nostro paese hanno introdotto cambiamenti di ampia portata alle strutture famigliari, conducendo a una ridefinizione dei loro tratti salienti. Cambiano i modi e i tempi con cui le famiglie si formano e si sciolgono, le traiettorie di vita individuali sono sempre più frammentate e le forme famigliari si moltiplicano (Barbagli et al. 2003; Ferro e Salvini 2007; Mencarini 2012). Come per molte altre città italiane ed europee, anche i dati della città di Torino rivelano un
quadro in veloce mutamento1. Tra il 1971 e il 2011, la popolazione del capoluogo piemontese è diminuita, passando da 1.167.968 a 872.367 abitanti, mentre il numero di famiglie è aumentato a causa della contrazione del numero medio di componenti per nucleo. Cresce il numero delle famiglie unipersonali, mentre diminuisce quello delle famiglie complesse e si diffondono nuove tipologie famigliari come i nuclei monogenitore, le famiglie ricostituite, le convivenze more-uxorio, le coppie o le famiglie con membri di cittadinanza straniera. Aumentano ugualmente le separazioni e i divorzi, anche tra coniugi di età più elevata. Questi cambiamenti, iniziati lentamente dagli anni Settanta, hanno subito un’accelerazione repentina nel passato più recente e l’insieme di queste nuove forme famigliari assume oggi un peso sempre più rilevante
Quando si rimane soli: separazioni e vedovanza
No full textNei grandi centri urbani come Torino, sempre più unioni coniugali si concludono con una separazione o un divorzio e lo scioglimento famigliare è diventato un evento che accomuna molti individui. Da qui l’aumentato interesse per lo studio delle conseguenze che uno
scioglimento coniugale può avere sullo stato di salute delle persone e dei meccanismi che legano la configurazione famigliare e le traiettorie di vita degli individui alla salute
Construction of a frailty indicator with partially ordered sets: A multiple-outcome proposal based on administrative healthcare data
Full text linkSpouses’ Health: What Happens Beyond the Widowhood Effect?
No full textObjectives. We focus on married couples, and we analyse how the susceptibility and survival of individuals can be influenced by the illnesses and death experienced by their spouses. Methods. We perform a cohort study following married couples (age 65–75 years) from 2001 to 2013. We monitor individual’s susceptibility status and three spouses’ illnesses (i.e. diabetes, cancer, and mental diseases). The methodology used is the Cox regression. Results. The initial cohort is composed of 22,639 couples. During the follow-up, 24% of the individuals dies, 91% experiences at least one susceptibility increase and 43% experiences one spouse’s illness. Results from the Cox regressions report a change in the individual health that is specifically related to the occurrence of the spouse’s diseases and death. Moreover, the three diseases hit individuals differently. Discussion. What emerges from this work is the importance of considering the mechanism of the widowhood effect with an extensive approach

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
