Un modello operativo di gestione delle risorse idriche nel Regenerative Design
No full textSempre più scarsa e meno accessibile, l’acqua sta assumendo i connotati di una risorsa pregiata in grado di alimentare marcate iniquità. Gli elevati consumi dovuti all’uso civile – nei settori domestico e terziario – accrescono la pressione sull’ambiente, tracciando una condizione di stress idrico molto alto in gran parte delle città italiane. Il tema della gestione delle risorse idriche all’interno degli edifici si pone quindi come un campo di indagine prioritario, e come processo centrale nell’approssimazione a un modello di sostenibilità nell’edificazione, oggi individuabile nel Regenerative Design. La scarsità idrica rappresenta un rischio pendente derivato da interferenze di natura ambientale, tecnologica, economica, sociale e politica, con conseguenze sulla disponibilità e l’accessibilità alle risorse.
La ricerca si pone di interpretare il principio di sostenibilità nella gestione delle risorse idriche, attraverso la comprensione delle principali pratiche di riferimento, negli edifici, per la raccolta, il trattamento e il riuso, che consentano di preservarne la quantità e la qualità – in un’ottica di circolarità, come diversi casi di studio sono in grado di documentare. Lo studio è volto a estendere i margini dell’analisi a tutte le componenti che contribuiscono, anche indirettamente, alla definizione del consumo lungo tutte le fasi di operatività dell’edificio e a integrare i criteri valutativi attraverso la costruzione di Key performance indicators, strumentali a definire la rilevanza delle strategie e l’affinità con gli obiettivi della ricerca. Il risultato è la proposta di un modello rigenerativo con strategie complementari di intervento nelle costruzioni, capace di fornire uno strumento di supporto nell’affrontare decisioni progettuali consapevoli e funzionali alla prevenzione del rischio di scarsità idrica.Increasingly scarce and less affordable, water is taking on the characteristics of a precious resource able to increase marked inequities. The high consumption due to civil use – in domestic and tertiary sectors – fuels the pressure on the environment, drawing a very high water-stress condition in most Italian cities. The issue of water resources management within buildings stands as a priority field of investigation, and as a central process in the transition to a sustainability model in construction, today recognizable as ‘Regenerative Design’. Water scarcity represents a pending risk derived from environmental, technological, economic, social and political interferences. It threatens consequences on the availability and affordability of resources. The research aims to interpret the sustainability principle in water resources management, through the understanding of the best practices for harvesting, collection, treatment and reuse – with a circular approach – to preserve water quantity and quality in buildings, as various case studies can attest. The work tries to extend the field of analysis to all the components that contribute, even indirectly, to water consumption along all phases of the building’s life cycle and to integrate the evaluation criteria through a set of Key performance indicators, instrumental to define the relevance of strategies and the affinity with the research objectives. The result is the proposal of a regenerative model with complementary approaches for buildings, capable of providing a support tool to address aware and functional design choices in preventing water scarcity risk
A Comparison Between Italian and French Case Studies on Urban Regeneration
No full textUrban regeneration is a process that aims to transform the existing city while improving its performance, adopting strategies for the recovery and enhancement of the building heritage. In the contemporary age, we are experiencing a phase of industrial crisis that is reflected in the consolidated European city themes of reactivation and rehabilitation, which are assuming a central role for both local and metropolitan communities. The aim of this paper is to highlight issues and strategies for sustainable urban regeneration from a socio-economic point of view. To achieve this, we will compare different case studies from Italy and France, all located in dynamic contexts, whose projects have been completed in the last ten years. The cases are gathered in two categories of brownfield land, each addressing a different perspective: ex-industrial areas and docks. Urban regeneration is a key challenge for the contemporary city. Restoring brownfield sites means putting the theme of sustainability, declined in all its forms, at the centre of the future city development process
Design the Urban Microclimate: Nature-based Solutions and Technology at Nexus
No full textThis chapter outlines the general impacts and direct consequences climate change is producing in urban areas, especially in terms of negative influence on urbanites’ thermal comfort, and how green infrastructure combined with appropriate building technologies could increase our climate-adaptive capacity, and reduce the various health risks associated with urban heat waves and soil sealing. The study focuses on urban microclimate and energy balance in the built environment, and discusses key challenges for successful implementation of integrated design solutions, at different scales, for climate change adaptation. Through the development of two experimental renovation case studies – i.e. the former slaughterhouse of Velletri, and the heritage “Leo” penicillin factory in Rome – the authors investigate the microclimatic impacts of different environmental design strategies, showing in particular the effectiveness of combined landscape technologies, levering on vegetation and soil permeability to mitigate the urban microclimate, as well as improve the outdoor thermal comfort of urban people
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
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
