The road towards sustainability: projects of renewal enhancement of green areas in the city: the Senigallia case study.
No full textIn 2010 the municipality of Senigallia, located in Marche region (Italy),requested to thethe Department of Agricultural Sciences together with the Department of TerritorialPlanning of the Alma Mater Studiorum of Bologna and in collaboration with four architects, two agronomists and communaltechnicians to draft the Green Masterplan (GM) of the city. Aim of the request was to promote a neat, homogeneous and sustainable development of the territory and improve the quality of life and the wellness of its inhabitants. It also targeted the reduction of the CO2, produced by the extension of the highway, that divided urban and rural landscape. In order to attain these objectives, the working group proposes to increase both the amount and the value of the green areas, and alsotheir level of interconnection.Specific guidelines for future planning and projects are proposed. The GM was approved and, since 2010, many projects have been proposed and realized during last years. The projects proposed and the ones that has been realized tried to create a big greenway, able to connect the northern zone of the town to the southern zone of the town, by the creation of new green areas, urban forests, tree-lines boulevards and green roundabouts. The article aim at describing these projects, which tried to enhance and protect the green areas of the city as a system. The approach that conceives green areas as residual elements, essentially serving as a décor, is surmountedby bringing back their leading role that inhabitants, ecological balance, and sustainability of our living models attach to it. The green presence is here considered as a new infrastructure which needs to be carefully planned, subjected to regulations and efficiently managed, used as a regulatory instrument for the territory, preserved and constantly maintained in good conditio
L'Officina del Sole
No full textLa Società Agricola “Officina del Sole” rappresenta un tipico esempio di azienda agricola multifunzionale. Sita a Montegiorgio (FM), si estende su una superficie di circa 40 ha in zona collinare. Acquisita nel 2009 da una giovane imprenditrice agricola locale, l’azienda, dotata di 3 case coloniche, due delle quali già ristrutturate a fini ricettivi (agriturismo, bed and brekfast) e dapprima destinata alla quasi totale coltivazione della vite e in parte riservata a seminativo, è stata oggetto di un progetto che ha coinvolto il Dipartimento di Scienze e Tecnologie Agro-alimentari dell’Università di Bologna (DISTAL) per la parte prevalentemente paesaggistica e di progettazione del verde ornamentale e lo spin-off HORT dell’Università Politecnica delle Marche per la scelta della ripartizione colturale. In particolare, il progetto ha previsto la progettazione dell’intera area, ponendo particolare attenzione all’analisi del territorio in cui l’azienda si inserisce, riproducendone quindi i tratti distintivi e caratteristici e tenendo conto della vocazionalità del territorio per la scelta delle colture. Per queste ragioni, è stata proposta una ripartizione colturale che ha previsto l’inserimento di vitigni e varietà di olivo e fruttiferi prevalentemente locali, volti a valorizzare il territorio e le peculiarità della zona, in termini anche di sostenibilità ambientale, economica e sociale, in quanto le colture si inseriscono perfettamente nel paesaggio e costituiscono parte integrante di percorsi didattici e socio-ricreativi proposti per incentivare l’offerta turistica della zona, grazie anche alla realizzazione di un complesso comprendente una cantina, un frantoio, un locale adibito alla trasformazione della frutta, una sala degustazione, un ristorante ed un punto vendita dei prodotti aziendali, nonché alla ristrutturazione di due case coloniche con rispettive corti, destinate al soggiorno ed al pernottamento degli ospiti . La finalità degli impianti è dunque prevalentemente produttiva, a scopo di trasformazione e vendita di prodotti di qualità legati al territorio, nonché destinata alla ristorazione per gli ospiti dell’intero complesso, che possono beneficiare di un paesaggio unico, grazie ad un progetto del verde che valorizza le peculiarità e le caratteristiche tipiche del paesaggio rurale marchigiano, esaltandone al massimo la sua bellezza
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
Brain asymmetry in resting state and during linguistic tasks in major depression vs. dysthymia: an EEG alpha study
Full text linkIntroduction: Mood disorders are relatively heterogeneous and there is limited research on the psychobiological distinctive features of Dysthymia with respect to Major Depression. In line with past studies, they are expected to exhibit inverted brain asymmetries. Objectives: We aimed to investigate altered asymmetry of EEG Alpha band in MDD, Dysthymia patients and healthy controls during resting state and two linguistic tasks: phonological and semantic. We hypothesized, in patients with Dysthymia compared with MDD, a greater extent of inverted hemispheric asymmetry due to the structured lifetime nature of their disorder. Methods: We recorded EEG Alpha activity as an index of cortical inhibition, in 20 MDD patients, 20 Dysthymic patients and 20 healthy controls (all groups matched) during the three tasks. Electrodes were clustered in four main regions, two anterior (left and right) and two posterior (left and right). Statistics were carried out by means of ANOVA. Results: In frontal sites, no Alpha asymmetry was found in the groups, but Dysthymic patients had an overall greater Alpha activity across all tasks. The same effect was found in posterior regions, but, in addition, greater Alpha on the left was found during resting state for all groups. Dysthymic patients only maintained this altered asymmetry also during the linguistic tasks. Conclusions: Our findings highlight the role of linguistic tasks in assessing deficits in hemispheric integration in mood disorders. Dysthymic patients, who suffer from a lifetime disorder, exhibited an overall greater cortical inhibition especially on the left posterior sites, which was not counterbalanced by left lateralization-inducing tasks
Estimating leaf area indexes for 10 years of simultaneous or gradual renewal of an exhausted poplar tree avenue
No full textThe management of old trees suffering from precarious health state and biomechanical issues represents a very common task for many cities in Italy. It is not possible to determine when or whether trees are going to fall, but renewal can be planned to prevent expensive management and monitoring practices in the face of poor biological, ornamental and architectural results, as well as of high levels of risk. To be precise, while the ornamental and functional services exhaust, the emotional value gets fuelled and surges over time by citizens' affection. Given this, renewal plans for tree-lined avenues are not welcomed and the lack of an effective, scientific-based communication could exacerbate the problem. The search for a shared method represents an objective starting line to assess and make far-sighted decisions. The work illustrates a method for evaluating and managing old and/or dangerous trees in urban environment so that citizens are involved too. Economic and environmental aspects are analyzed by comparing the safeguard of an old tree line both to simultaneous or gradual renewal plans. Here we focus on the extent of the environmental services brought in urban areas by the diversely managed tree lines, estimating their leaf area indexes along 10-year span. Basing on results, Public Administrations can show citizens clear and objective data making management choices and strategies easier to share and agree with. Even though necessary and fundamental, the research for a comprehensive assessment of economic, social and environmental aspects related to tree lines is poorly explored
