Salute e immigrazione: un progetto di prevenzione e promozione della salute psichica dell’immigrato
No full textViene presentato un progetto svolto in un centro ascolto di Ancona, su soggetti immigrati sul tema della salute e dell’integrazione sociale. La criticità della diversa percezione sociale degli stranieri rispetto alla salute è un elemento centrale non solo per la tutela della loro salute ma per comprendere la loro cultura e promuovere l' integrazione
Che cosa è e come interrogare un testimone? Un confronto tra la realtà professionale e i contributi della ricerca psicologica
No full textVengono presentati i risultati di una ricerca che pone a confronto l’intervista cognitiva con altre strategie di indagine di polizia. I risultati mettono in evidenza come l'intervista cognitiva permetta di facilitare i ricordi corretti e di dimunure le confabulazioni e le non risposte dei soggetti intervistati

Urban food strategies and sustainable agri-food systems: Results of empirical analysis in Palermo
Full text linkIn developed economies, there is an increasing shift in food production from places of production to places of consumption. According to the economic logic of production costs, today many agri-food products are produced in one part of the continent and made available for consumption in other parts. This situation, although justified from an economic point of view, leads to the impoverishment of territories as many economic activities disappear from the production scenario. In this work, the agrifood policy of the city of Palermo is analyzed. In particular, we investigated the fruit and vegetable market in Palermo. The empirical verification shows that most of the fruit and vegetables available for consumption in the metropolitan area of Palermo do not come from Sicilian farms. This availability-consumption pattern of fruit and vegetables, fuelled by the consumption demand expressed by many consumers who give much weight to the price of the commodity over other variables, highlights the fact that the metropolitan area's current food policy results in the impoverishment of rural areas
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
Dispelling the Myths Behind First-author Citation Counts
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
