The assessment of human health impact caused by industrial and civil activities in the Pace Valley of Messina
No full textThe impact of industrial and civil activities on an agricultural and residential area is presented in a detailed
and global analysis. The examined area is the Pace river valley situated in the northern zone of Messina
(Italy). The sources of pollution present in the area are: a Municipal Solid Waste Incinerator operating since
1979, a disused urban solid waste landfill which was used for 30 years, an urban solid waste treatment facility
with heavy vehicles traffic, and two open pits for the production of bitumen. Large quantities of toxic,
carcinogenic substances and criteria pollutants are released into the environment and represent potential
hazards to human health. The analysis is performed using the EHHRA-GIS tool which employs an integrated,
multimedia, multi-exposure pathways and multi-receptor risk assessment model that is able to manage all
the steps which constitute the human health risk analysis in a georeferenced structure. The transport of
pollutants in different environmental media is assessed applying models (AERMOD, GMS, CALINE) that take
into account the particular three-dimensional morphology of the terrain. The results obtained, combined
with a probabilistic risk assessment and a sensitivity analysis of calculation parameters, are a comprehensive
assessment of the total human health risk in the area. Finally human health risks caused by toxic and
carcinogenic substances are compared with acceptable legal limits in order to support environmental
managers' decisions
Le possibilità dell'utopia. Anna Freud e il rapporto tra psicoanalisi e pedagogia
No full textL’attuale statuto epistemologico della pedagogia, sempre più orientato a definirsi con criteri che accomunano gli aspetti più tradizionalmente scientifici con quelli maggiormente innovativi e flessibili, accoglie, nella dimensione teorico-concettuale e pratico-operativa, alcune indicazioni che, in realtà, appartengono al sapere della psicoanalisi freudiana e post-freudiana. Nella pratica, sembra, cioè, verificarsi quanto la teorizzazione non ha ancora chiaramente concettualizzato: già da molto tempo, l’evento educativo si attualizza con modalità e procedure che comprendono orientamenti psicoanalitici, mentre solo in un recente passato si è tentato di convogliare questi assunti nella riflessione pedagogica; sono, cioè, entrati a far parte dell’operare educativo molteplici orientamenti derivanti
dalla teoria e dalla clinica freudiana (e post-freudiana)
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
Assessment of the human health risk using a Gis approach: the case of the Pace Valley
No full textAssessing and managing environmental risks resulting from industrial and civil activities are themes of great and continually increasing complexity. In performing environmental risk assessments great effort is generally devoted to calculate risk on human health due to exposure to carcinogenic or toxic substances which may be present in the air, soil, water and foods. The aim of the paper is to present a procedure for an integrated approach to human health risk assessment through the description of an improved GIS application developed to manage all the steps of the procedure in a georeferenced framework. The case study of the Pace Valley in Sicily illustrates the way this tool can be applied particularly in order to evaluate the impact of contamination due to activities related to urban waste management

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
