La famiglia tra mutamenti demografici e sociali
No full textPer molti decenni, sotto l'influenza degli studi pionieristici di Laslett, l'attenzione degli studiosi della famiglia si è concentrata soprattutto sugli aspetti più strettamente legati alle strutture familiari e alle modalità di coabitazione. Se da una parte si è fornita una base per interpretare le più ampie trasformazioni sociali e demografiche avvenute tra età moderna e contemporanea, dall'altra, si è forse perso di vista il più articolato sistema di relazioni tra famiglia, individui e contesto socioeconomico. A seguito del cambiamento nell’approccio allo studio storico-demografico della famiglia, passato dall’analisi statica delle classificazioni strutturali all’esame dinamico e longitudinale dei gruppi familiari, l’interesse si è focalizzato sulle nuove tematiche relative al ruolo della famiglia all’interno dei processi e dei meccanismi demografici, richiedendo una molteplice prospettiva disciplinare.
Gli interventi raccolti in questo volume testimoniano la multidisciplinarietà del nuovo approccio allo studio della famiglia, esplorando non solo le aree d'indagine tipiche della ricerca storico-demografica, ma estendendo ulteriormente il campo di indagine ad altre possibili accezioni di famiglia

No full textPer molti decenni, sotto l’influenza degli studi pionieristici di Laslett, l’attenzione degli studiosi si è concentrata soprattutto su aspetti più strettamente riguardanti le strutture delle famiglie e le modalità di coabitazione. Se da una parte si è fornita una base per interpretare più ampie trasformazioni sociali e demografiche avvenute tra età moderna e contemporanea, dall’altra si è forse perso di vista il più articolato sistema di relazioni tra famiglia, individui e contesto socio-economico. In questi termini, un approccio interdisciplinare allo studio della famiglia nel passato risulta auspicabile e necessario. Gli interventi raccolti in questo volume indagano l’evoluzione della famiglia esplorando non solo le aree d’indagine tipiche della ricerca storico-demografica, ma ne estendono ulteriormente il campo di indagine ad altre possibili accezioni di famiglia. In questa breve introduzione presentiamo gli interventi raccolti ripercorrendone il filo conduttore
I living arrangements delle seconde generazioni di immigrati europei negli Stati Uniti all'inizio del XX secolo
No full textAlthough theory underlines that immigrants usually tend to acquire the behaviors and norms of the receiving countries quickly, some researches have focused on how individual characteristics and the values and norms of the origin area determine different paths of this process. Moreover, the speed of the assimilation of the new social norms is usually interpreted as a clear indicator of immigrant integration into host societies. At the same time, literature has markedly underlined the role of strong or weak family ties in modelling the transition to adulthood especially when leaving or remaining longer in the parental home is taken into consideration. This study intends to use the 1910, 1920, and 1930 IPUMS census samples to analyze how the country of origin linked to different contextual factors affects the age of still leaving in the parental home among European second generations immigrants in the United States by comparing them with other immigrant groups. Results suggest that children of immigrants tend to live longer with their parents and thus to delay family formation compared to US white population. However, relevant differences emerge between different countries suggesting the potential effect of cultural maintenance among children of European second generations
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
