    YOUNG PEOPLE AND SOCIAL CHANGE. THE SOCIAL CONSTRUCTION OF THE TRANSITION FROM ADOLESCENCE TO ADULTHOOD

    No full text
    Youth is generally perceived as a temporary and transitory phase from childhood to adulthood, in which the specific social roles experienced as adolescents are gradually replaced by new roles, tasks and responsibilities characterizing adulthood. In contemporary society this shift is achieved through the accomplishment of a number of transition phases. Accordingly, people aged 15-34 years are generally defined as young. Nevertheless, labour market employment, residential independence, marriage and parenthood cannot be considered as essential and sequential steps. In addition, specific features characterising local contexts have a crucial role in the way these steps are achieved. In this work we investigate these topics in order to understand to what extent a single definition of youth cannot describe the whole range of dimensions concerning young people, even within the Italian context

    Interrogare nell'approccio standard: l'inchiesta campionaria

    No full text
    il contributo è dedicato all'interrogazione nell'approccio quantitativo. Partendo dalla definizione di inchiesta campionaria, che costituisce la formavdi indagine prevalente nella ricerca standard, ne vengono evidenziate le caratteristiche costitutive e le differenze con il sondaggio. Vengono poi affrontate tutte le questioni teoriche e pratiche connesse sia alla preparazionevdello strumento principale di rilevazione delle informazioni, il questionario, sia alla scelta delle modalità di somministrazione. Infine, ampio spazio è dedicato alle procedure di selezione dei casi da sottoporre a interrogazione, il campionamento. Sono introdotti a questo proposito i concetti di probabilità, rappresentatività e inferenza, e vengono passati in rassegna i diversi tipi di campione utilizzati nella ricerca sociale

    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

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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
