Popolazione e invecchiamento nelle Marche
No full textL'invecchiamento della popolazione è un processo che coinvolge la nostra società ponendo una serie di sfide di natura economica, sociale e culturale.
In questo volume ci siamo occupati del fenomeno ponendo l'attenzione sulla comparazione Marche-Italia e analizzando i diversi aspetti che lo riguardano, dalle sue determinanti (nascite, morti e migrazioni), in una prospettiva storica di circa 140 anni, all'evoluzione della struttura per età e sesso, che permette di catturare la dinamica dell'invecchiamento demografico.
L'invecchiamento tuttavia non è un processo uniforme ed omogeneo e diverse caratteristiche possono determinare differenti invecchiamenti. In questo lavoro siamo partiti dalla definizione più utilizzata di invecchiamento in termini di anni vissuti, per poi adottare soglie dinamiche, spostando l'accento dagli anni vissuti a quelli che restano da vivere. In quest'ottica abbiamo proposto due criteri di mortalità differenziale, tenendo conto da un lato dei divari di sopravvivenza in presenza di diversi livelli d'istruzione, e dall'altro delle diverse condizioni di salute, che incidono profondamente sulla qualità della vita, in relazione al sesso, al livello d'istruzione, al livello di reddito.
L'invecchiamento è una sfida ma anche una grande conquista legata alla longevità, e se opportunamente gestito e promosso attraverso una cultura d'invecchiamento attivo può diventare un'opportunità sociale ed economica. E' possibile tuttavia fermare, o almeno rallentare il processo d'invecchiamento in atto? In questo volume abbiamo cercato di fornire alcune possibili risposte a questa domanda
International retirement migrants
No full textInternational retirement migration (IRM) is hard to quantify yet is an increasingly important element in global migration, especially from more wealthy countries. IRM is driven by demographic, economic and lifestyle factors and is strongly interrelated with tourism flows and destinations. Conventionally seen as a privileged, socio-economically selective migration, it also attracts ‘pension-poor’ people seeking cheaper as well as more satisfying retirement lifestyles in warmer climates and pleasant urban and rural landscapes. Three regional systems of IRM are described: the European north-to-south migration of retirees to places such as southern Spain or rural Tuscany; the American system from North to Latin America, notably Ecuador; and an Asian system focused on Thailand as key destination. Despite systemic shocks such as the global economic crisis and the Covid-19 pandemic, IRM is likely to increase in the future, with new typologies and geographies of movement emerging
Le determinanti delle rimesse: evidenze empiriche dalla comunità serba e albanese in Italia
No full textAgeing in a foreign country: determinants of self-reported health among older migrants in Italy
No full textWithin a framework of increasing ethnic diversity of developed countries' population, a growing body of migration literature has focused on migrants’ health. Nonetheless, although ageing is a major demographic trend of western societies involving both natives and migrants, older migrants remain a relatively under-researched group so far. In Italy, despite the increasing incidence of migration on total population, its fast ageing process, and the acknowledged difficulties that migrants face in becoming full members of the Italian society, thus far, very little is known about the migrant population approaching old age. Our study focuses on the main protective and risk factors of health in later life using a unique dataset from the ‘Social condition and integration of foreign citizens’ (SCIF)’ survey conducted by ISTAT between 2011 and 2012. Our findings show that a number of variables related to both the migration process and living conditions in Italy are important determinants of self-rated health, stressing the necessity to design and implement tailored policy responses and services that address migrants’ vulnerabilities in later life
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
