Legati alla Natura da bambini, per diventare adulti che hanno cura dell'ambiente (Connected to Nature as children, to become environmentally-conscious adults).
Full text linkUna progettazione che integri elementi naturali con il contesto residenziale urbano è importante per i riconosciuti effetti positivi della Natura su individui e comunità. In parallelo, instaurare un legame affettivo con l’ambiente naturale durante l’infanzia influisce sul comportamento proambientale dell’adulto, ovvero tutti quei comportamenti finalizzati a diminuire i danni all’ambiente naturale e a preservare il territorio e le sue risorse. L’obiettivo di questo contributo è illustrare gli effetti positivi che il legame bambino-Natura può avere per la cura dell’ambiente. L’articolo si chiude con una riflessione sull’importanza di attuare politiche partecipative orientate a sostenere e incrementare il legame affettivo con la Natura di adulti e bambini, non solo per aiutarli ad apprezzare appieno il Suo potenziale rigenerativo, ma anche per capire l’importanza di preservarla.Integrating the environment in urban planning and management is important, due to the recognised positive effects of Nature on individuals and communities. At the same time, forming a positive relationship with the natural environment during childhood affects adult’s individual attitudes towards Nature and pro-environmental behaviour, namely those actions aimed to prevent damages to natural environment and protect natural resources. The aim of this work is to highlight the beneficial effects a positive child-Nature relationship can have on environmental care. This paper ends with a reflection on the importance to act participative policies in order to sustain and enhance child and adult’s relationship with Nature, not only to help them appreciate Nature’s restorative potential, but also to encompass the importance of taking care of it
Confronto fra un modello di regressione multipla e un modello connessionista per la previsione della prestazione universitaria
No full textIl presente lavoro si propone di confrontare due metodi di previsione, uno che si basa su un modello di regressione multipla e uno che considera un modello connessionista, applicati in un contesto di orientamento alla scelta universitaria. Il campione è costituito da 250 studenti iscritti alla Facoltà di Economia e Commercio di Padova nell'AA 1996/96. E' stata studiata la relazione tra alcune variabili considerate come predittori (punteggi ottenuti al test di ammissione al Corso di laurea, voto di maturità ed altre) e il numero di esami sostenuti e la media dei voti accorpate in un'unica variabile tramite la quale sono stati individuati tre livelli di prestazione. Il confronto tra i livelli osservati e quelli attesi, effettuato con statistiche non parametriche, ha evidenziato una sostanziale omogeneità di risultati, ma ha anche messo in luce alcune interessanti peculiarità
Distribution of the predatory mite Amblyseius andersoni (Acari: Phytoseiidae) on different apple cultivars
No full textDetection and characterization of a vinyl chloride plume inside an urbanized area
No full textThe paper deals with a sandy confined aquifer of alluvial origin
contaminated by vinyl chloride and located in the Po Valley immediately to
the south of the Po River and 5 km to the north of the city of Ferrara (northern
Italy). The investigation identified, inside a mainly urbanized area, a plume
with a length of 1.7 km and a maximum width of 0.3 km with vinyl chloride
(VC) concentrations of up to more than 11 000 ppb and total absence of other
chlorinated ethanes, ethenes, and ethylene. To optimize the VC analysis,
short-term low-flow purging using peristaltic and inertial pumps were used to
collect samples
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
Un secolo di turismo in Valle Sabbia: storia, rappresentazioni, prospettive

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
