Palermo si cura. Pratiche culturali di mutuo soccorso come risposta alle fragilità della città (post)pandemica
2023
In un quadro di riferimento in cui la crisi è globalizzata ma diseguale e in mancanza di un sistema di welfare capace di rispondere alle urgenze dei contesti e dei gruppi sociali più marginalizzati, una risposta ai nuovi bisogni sociali ed individuali è stata offerta da reti solidali e da pratiche di mobilitazione dal basso che svolgono un ruolo di agency territoriale, spesso indipendentemente o in assenza di Istituzioni. Nel contesto palermitano un impegno agito da una pluralità di soggetti culturali già attivi sul territorio, riuniti in un’assemblea pubblica (Palermo si cura), durante il periodo del primo lockdown hanno dato vita ad azioni di mutuo soccorso per rispondere all’emergenza ec…
TOWARDS THE DECARBONIZATION OF THE EU BUILDING STOCK: AN INTEGRATED BUILDING STOCK RENOVATION MODELING APPROACH
2020
In Europe, the residential building stock is responsible for about 40% of the energy demand and about 36% of the CO2 emission at global level. Considering that almost 70% of the existing building stock will still be used in 2050, a long-term vision is needed to align with future challenges to avoid having significant increases in carbon emissions. The European policymakers have a long-recognized potential energy saving associated with the renovation of the existing building stocks, as demonstrated by the directives on the Energy performance of buildings (EPBD), introducing also the need to developed an integrated buildings design approach with environmental analysis. The purpose of this the…
I piani energetici ambientali regionali. Applicabilità degli indicatori proposti a scala nazionale (ISPRA) ed europea (EUROSTA).
2014
As it is well known, indicators represent effective tools in the aim of designing, monitoring and verifying energy and environmental Masterplans. At this regard, a large number of indicators do exist both at European and country Italian levels which designers can usefully apply to. Anyway, being such indicators released at a general European level, their actual verifiability should be properly checked when them are applied to the local level of a given territory. In the present work this issue is approached by referring to the Sicilian Energy and Environmental Masterplan (PEARS): on purpose, the themes proposed at European (Eurostat) and country Italian (ISPRA) levels have been compared wit…
The Lean Urban Policies’ Design A values-centered method for sustainable urban planning.
In these past years, the necessity and urgency has emerged for policies tied to an alternate development to be efficiently applied, and not limited to single operations. The policies must be defined by a clear and effective method of action. Starting by investigating what are the relationship among human being, built environment and natural sources, in fact, we think it is possible to enrich the sustainable urban planning policies with new contents and possibly, new tools. By describing the frame, the objective is to define the most effective method, to be able to convey an effective project action and governance for the territory, to achieve predefined social and energy based objectives. …
Interferenza tra il livello dell’oggetto e attributi di base in stimuli visivi: studio su pazienti con lesione cerebrale.
2011
Introduzione. In compiti di ricerca visiva i processi top-down coinvolti nel riconoscimento della forma dell’oggetto possono interferire nella elaborazione bottom-up degli attributi elementari che compongono l’oggetto. La performance in tali compiti può essere facilitata dopo inibizione selettiva della corteccia parietale destra tramite r-TMS. In questo studio abbiamo indagato il ruolo di lesioni cerebrali nei compiti di ricerca visiva per singole caratteristiche caratterizzati da interferenza tra il livello dell’oggetto e degli attributi elementari. Pazienti con lesione focale del lobo parietale potrebbero paradossalmente non risentire dell’effetto interferente esercitato dal riconosciment…
Perspectives et bilan après 20 ans de recherche au bas de la pyramide, une étude bibliométrique pour le futur du management international
2021
Cet article propose une analyse bibliométrique du champ des stratégies au bas de la pyramide (BoP) fondée sur 364 articles citants issus de la plateforme Web of Science fournissant une base de 15 292 références. Différents outils sont mobilisés, pour mettre en évidence la structure du champ BoP d’une part, et pour identifier les tendances du front de recherche d’autre part. Six groupes structurant le champ émergent des analyses, chacun mettant en évidence un courant de recherche, et cinq tendances rythment les recherches actuelles sur le BoP. Ces analyses permettent de proposer quatre perspectives pour le futur du management international.
Exploring the contribution of grassroots innovations to justice: using the capability approach to normatively address bottom-up sustainable transitio…
2020
There is growing interest in the potential of grassroots innovations for the transition towards more just and sustainable societies. Nevertheless, there is lack of clear normative discussion regarding these processes. The paper strives to propose and test a framework that enables an analysis of how and in which sense specific grassroots innovation processes may be contributing to the construction of more just societies. To this end, we connect elements of the multi-level perspective on sociotechnical transitions (frequently used in the analysis of grassroots innovations) with elements of the capability approach, which offers a multi-dimensional perspective to justice. The framework is used …
Biochar and Forage Peanut improve pastures: Evidence from a field experiment in Brazil
2023
Pasturelands, often degraded, represent most of the converted lands globally. It is important to understand how different pasture management approaches can improve soil quality, increase feed production and farmer income. Here, the impact of different soil enhancers on soil quality and productivity of three cultivars of Brachiaria (Syn. Urochloa) forage grass is presented. Soil enhancers included: biochar - a carbon-rich product from biomass pyrolysis, moinha (local charcoal residue), traditional fertiliser containing nitrogen, phosphorus and potassium, lime, and forage peanut (Arachis pintoi cv. Amarillo). Considering the total biomass produced over the experiment (sum of four harvests), t…
A Top-Down Method for Long-Term Investing
2021
This paper bases long-term investing on a tradeable stochastic discount factor (SDF), relates it to the growth optimal portfolio and argues for a top-down method, where modeling efforts are directed at capturing its long-run dynamics in a generalized setting. This differs from the common, cumbersome bottom-up method of modeling many risky securities in the marketplace. Various optimal portfolio strategies can be implemented efficiently using fractional expectations of the SDF. This paper illustrates empirically for the US stock market that the proposed method leads to higher wealth, higher returns on investment and higher long-term utility levels.
Who Is the Social Entrepreneur?
2021
Social entrepreneurs are understood as individuals integrated within a society, being continually influenced by the environment. This chapter explains that the constitution of a social entrepreneur is determined by external variables (environmental influences) and internal variables (characteristics of the individual). Among the external influences, we should highlight the Triple Bottom Line phenomenon, the Corporate Social Responsibility trend, technological advances and the Sustainable Development Goals. The intrinsic motivators would be divided into three different dimensions: attitude and intention, personality traits and leadership skills. The synergies produced as a consequence of the…
