Exploring the spatial structure of housing prices under economic expansion and stagnation: The role of socio-demographic factors in metropolitan Rome, Italy
No full textAnalysis of changes over time in the spatial structure of housing prices provides reliable information to infer latent patterns and processes of urban growth. Although the 2008 financial recession had a negative impact on building activity in Europe - and especially in southern Europe - the overall impact of the global crisis on the spatial structure of housing prices has been occasionally investigated at the local scale. The present study compares the spatial structure of transaction prices under economic expansion (2003–2009) and recession (2009–2015) in Rome (central Italy), evaluating the combined influence of demography, land-use and territorial factors. Transaction prices increased significantly during expansion and decreased less sharply during recession. The highest housing prices were recorded in downtown Rome. Convergence and divergence in the level of housing prices between urban and rural areas were observed respectively during economic expansion and recession. The empirical results of this study indicate that the 2008 financial crisis influenced considerably the spatial structure of housing prices in Rome, weakening the urban-rural divide and consolidating the gap between wealthy and poor neighbourhoods
Measuring local well-being: a comparison among aggregative methods for the equitable and sustainable well-being
No full textWithin the "BES’ Provinces" Project this work aims to compare different synthesis techniques of elementary indicators for each BES domain. Firstly, 41 elementary indicators are selected from the original dataset of 88 indicators, available for the year 2014, which guarantee robustness, reliability and relevance in accordance with the BES meaning.
Motivated by the debate on the need to summarize the information arising from a large set of variables, in this paper we discuss three different aggregation methods: the Adjusted Mazziotta-Pareto Index, the arithmetic mean weighted by the Gini coefficients of the elementary indicators and a mixed approach based on the two
Comparing Equitable and Sustainable Well-being (BES) across the Italian provinces. A factor analysis-based approach
No full textThis paper applies the factor analysis to reduce the huge number of variables included in each of the 11 domains that constitute the Equitable and Sustainable Well-being (BES) of the Italian provinces. Using this method, we extract the minimum number of indicators able to summarize the relationship within the wellbeing dimensions. Based on these results, for each domain and for each Italian province, we construct a composite indicator that is a linear combination of the estimated factor scores, with weights based on the Gini index of concentration. In particular, we associate smaller weights to those factors that exhibit a more homogeneous distribution across the provinces, while greater weights will be
associated with those factors that are more concentrated in few geographical areas
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
