Full text linkDifferenze territoriali e specializzazioni nell’industria meccanica in Italia. Un’analisi cluster dei dati censuari 1991 e 2001
No full textIn questo capitolo presentiamo i risultati dell’analisi relativa ai dati censuari deglioccupati nell’industria metalmeccanica: un vasto aggregato di attività di produzionee trasformazione dei metalli, di produzione di macchinari, di mezzi ditrasporto, e di componenti e semilavorati meccanici necessari alla loro produzione.In questo lavoro proponiamo di utilizzare l’analisi cluster quale metodologiastatistica per individuare una tipologia di SLL che tenga conto congiuntamentedella dimensione del SLL oltre che della specializzazione manifatturiera emeccanica e della presenza di imprese di piccola e media dimensione. L’obiettivoè definire una classificazione dei territori che metta in luce le differenze nell’intensitàdi specializzazione meccanica. Il nostro contributo originale consistenell’utilizzo di questa tecnica per evidenziare il fenomeno di contiguità spazialetra SLL con differenti gradi di specializzazione e dimensione di impresa, un fenomenonoto nelle ricerche empiriche su singoli distretti e sistemi produttivi locali,ma che finora non aveva trovato riscontro in un’analisi sistematica che consentissedi avere un quadro d’insieme sull’intero paese
Kinlessness at Older Ages: Prevalence and Heterogeneity in 27 Countries
Full text linkObjectives. We provide recent and detailed estimates of the prevalence of kinlessness (i.e., people lacking [close] kin) among older individuals in 27 countries. We add to the literature by considering a broad range of kinship ties and examining within-country variabilities by age, sex, education, and rurality of the residential area.
Methods. Using data from Wave 8 (2019-2020) of the Survey of Health, Ageing, and Retirement in Europe (SHARE), we estimated the prevalence of kinlessness among individuals aged 65 and over in 26 European countries and Israel. We considered different definitions of kinlessness, from a less restrictive (based on the absence of both a partner and children) to a more restrictive one (absence of partner, children, grandchildren, parents, and siblings).
Results. Kinlessness varied considerably across countries. The percentage of people aged 65 and over who lacked a partner and children ranged between 2-3.5% in the Czech Republic, Romania, Israel, and Bulgaria to more than 8% in Switzerland, Spain, Belgium, and Malta. The percentage of older people lacking all close kin considered (partner, children, grandchildren, parents, and siblings) ranged from 0.1 to 4.1%. In addition, there was substantial heterogeneity in kinlessness in some countries by age, sex, and rurality of the residential area, whereas, except for a few cases, we did not find significant differences by education.
Discussion. Understanding the prevalence of kinless older adults is critical for policymakers and healthcare providers to design appropriate support systems for this potentially vulnerable group of people
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
A Reflection on Economic Uncertainty and Fertility in Europe: The Narrative Framework
Full text linkThe generalized and relatively homogeneous fertility decline across European countries in the aftermath of the Great Recession poses serious challenges to our knowledge of contemporary low fertility patterns. In this paper, we argue that fertility decisions are not a mere “statistical shadow of the past”, and advance the Narrative Framework, a new approach to the relationship between economic uncertainty and fertility. This framework proffers that individuals act according to or despite uncertainty based on their “narrative of the future” – imagined futures embedded in social elements and their interactions. We also posit that personal narratives of the future are shaped by the “shared narratives” produced by socialization agents, including parents and peers, as well as by the narratives produced by the media and other powerful opinion formers. Finally, within this framework, we propose several empirical strategies, from both a qualitative and a quantitative perspective, including an experimental approach, for assessing the role of narratives of the future in fertility decisions
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
