No full textThis paper studies the determinants of internal migration of resident foreigners in Italy from 1995 to 2006 by means of a new version of gravity model. The results show that the demographic and economic characteristics of regions of origin act as pull factors while neither the demographic nor the economic features of destination regions have effect as push determinants
Containing urban expansion: Densification vs greenfield development, sociodemographic transformations and the economic crisis in a Southern European City, 2006–2015
No full textSelf-contained urban expansion is associated with accelerated (or decelerated) rates of metropolitan growth depending on the different phases of the economic cycle; self-contained growth is usually more intense during recessions. To verify such framework, a specific approach based on novel indicators of urban growth (2006–2015) was illustrated and applied to a metropolitan region in southern Europe (Athens, Greece) experiencing
progressively worst economic conditions as a consequence of the 2007 crisis. This approach allows assessment of greenfield development and densification processes – intended as a specific form of brownfield development – at municipal level, with the aim to relate such patterns with the socioeconomic local context. The empirical results of this study outlined that total urban expansion decreased over time with greenfield development.
The share of brownfield development in total urban expansion was relatively low in the first time interval and increased afterwards, fuelling metropolitan growth in a period characterized by a generalized decline of building activity. High per-capita income and local specialization in advanced services were characteristic traits of peri-urban districts with a particularly high rate of brownfield development. A comparative
analysis of spatial patterns of greenfield and brownfield development forms a basic knowledge informing strategies that promote self-contained urban expansion
Income disparities, metropolitan hierarchy and the socioeconomic background of italian local districts
No full textThis chapter evaluates short-term socioeconomic dynamics of local districts with the aim at identifying multifaceted dimensions of regional competitiveness in Italy. The spatial distribution of per worker, per head and per land value added was correlated with several predictors of the socioeconomic background of local districts. The intrinsic geography of economic development was investigated adopting a data mining approach that assesses the multiple relationship between value added and contextual variables. The spatial distribution of value added diverged along urban-rural, North-South and elevation gradients. Average district (per land) value added was highly correlated with indicators of population density and urban centrality. The joint use of value added and social indicators allows a comprehensive analysis of changes in urban spatial structures of highly divided countries
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

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
