A multi-methodology and sustainability-supporting framework for implementation and assessment of a holistic building renovation

La ristrutturazione degli edifici in futuro dovrà essere condotta secondo una prospettiva più olistica legata alla sostenibilità vista in una più ampia gamma di obiettivi/criteri e facilitata dagli scenari di ristrutturazione possibili. La ristrutturazione degli edifici dovrebbe servire a migliorarne le performance al fine di soddisfare le esigenze degli utenti, rendendo questi ultimi meno vulnerabili in relazione ai futuri costi energetici. Vi è un grande potenziale per ridurre il consumo di energia negli edifici esistenti. Tuttavia, ciò non deve comprometterè i valori architettonici e di qualità che rendono particolari. Pertanto, non possono essere semplicemente rinnovati, ma devono subir…

'Participative foresight scenario mapping': adapting an MCM method to appraise foresight scenarios for the long term sustainable development of a sma…

2016

Multi-criteria mapping (MCM) appraisal has been used in projects involving decisions related to specific technologies or policies in risk analysis. In this research, MCM has been adapted for appraising in a participative way holistic scenarios for a small isolated island. The procedural novelty relies on how the scenario building and the criteria selection were undertaken. Two scenarios for Flores Island (Portugal) were developed in a two step process involving, firstly, specialised stakeholders and decision-makers, and secondly, lay citizens. The scenarios aimed at proposing alternative visions of future. This article analyses the methodological aspects of the project (scenario development…

An ex post criticism, based on stakeholders’ preferences, of a residential sector’s energy master plan: the case study of the Sicilian region

2016

Energy master plans are important tools for an effective and sustainable land governance. On the other hand, the stakeholder role in setting priorities for planning energy interventions is dramatically increasing, also in the light of recently issued European directives. The priorities of energy-saving measures of the Sicilian energy and environmental master plan were originally established with the application of typical economic indicators (the cost of saved energy and the cost of avoided pollutant emissions). During the prioritization process, there was a minor contribution from stakeholders who were not directly involved in the priority-setting process but were only asked to express the…

Consumers’ criteria to select food retailers revisited in the current environment.

2022

Food retailing is undergoing major transformations, particularly in France. Hypermarkets are declining, hard-discount stores are gentrifying, e-commerce is mixing with physical distribution, convenience stores are gaining presence and market shares, other forms are emerging: short, collaborative or cooperative channels. Consumers are clearly changing their buying patterns. How do people currently select a form of sale? Are there any changes in their selection criteria or in their perception of food retailing that can explain that they are turning away from hypermarkets to go to more meaningful places? The objective of this research is to revisit the consumers’ criteria to select a form of s…

Multivariate Assessment of Procedures for Molecularly Imprinted Polymer Synthesis for Pesticides Determination in Environmental and Agricultural Samp…

2021

In the case of quantitative and qualitative analysis of pesticides in environmental and food samples, it is required to perform a sample pre-treatment process. It allows to minimalize the impact of interferences on the final results, as well as increase the recovery rate. Nowadays, apart from routinely employed sample preparation techniques such as solid-phase extraction (SPE) or solid-phase microextraction (SPME), the application of molecularly imprinted polymers (MIPs) is gaining greater popularity. It is mainly related to their physicochemical properties, sorption capacity and selectivity, thermo-mechanical resistance, as well as a wide range of polymerization techniques allowing to obta…

Análisis Económico del Derecho (2010/11)

2010

Parece que Derecho y Economía sean dos disciplinas que tienen poco que ver entre sí. Diferencias de objeto y método han venido manteniéndolas separadas, a pesar de que los estudios de Economía, en su acepción inicial de Economía Política, tuvieron su origen y se desarrollaron en las facultades de Derecho españolas.Esta separación no evitaba algún contacto eventual en aquellos campos en los que la coincidencia era más obvia: áreas híbridas, más jurídicas para el análisis económico y más económicas para el análisis jurídico como las describe el profesor Santos Pastor: los tributos y, ocasionalmente, algunas modalidades de regulación.Ahora bien, desde los años 60 y, originalmente en EE.UU., se…

Local Expected Shortfall-Hedging

2001

This paper proposes a self-financing trading strategy that minimizes the expected shortfall locally when hedging a European contingent claim. A positive shortfall occurs if the hedger is not willing to follow a perfect hedging or a superhedging strategy. In contrast to the classical variance criterion, the expected shortfall criterion depends only on undesirable outcomes where the terminal value of the written option exceeds the terminal value of the hedge portfolio. Searching a strategy which minimizes the expected shortfall is equivalent to the iterative solution of linear programs whose number increases exponentially with respect to the number of trading dates. Therefore, we partition th…

Inverse Malthusianism and Recycling Economics: The Case of the Textile Industry

2020

The current use of natural resources in the textile industry leads us to introduce a new economic concept called inverse Malthusianism describing a context in which population grows linearly and resource consumption grows exponentially. Inverse Malthusianism implies an exponential increase in environmental impact that recycling may contribute to reduce. Our main goal is to extend the analysis of materials selection under the principle of equimarginality proposed by Jevons. As a first result, we show the particular circumstances under which policies excluding recycled supplies are never optimal. We also aim to overcome the difficulties of reducing environmental aspects to monetary units. To …

Graph Clustering with Local Density-Cut

2018

In this paper, we introduce a new graph clustering algorithm, called Dcut. The basic idea is to envision the graph clustering as a local density-cut problem. To identify meaningful communities in a graph, a density-connected tree is first constructed in a local fashion. Building upon the local intuitive density-connected tree, Dcut allows partitioning a graph into multiple densely tight-knit clusters effectively and efficiently. We have demonstrated that our method has several attractive benefits: (a) Dcut provides an intuitive criterion to evaluate the goodness of a graph clustering in a more precise way; (b) Building upon the density-connected tree, Dcut allows identifying high-quality cl…

Architectural technologies for life environment: Spent coffee ground reuse in lime-based mortars. A preliminary assessment for innovative green therm…

2022

Spent coffee ground, the residue obtained from the brewing process, is the primary unavoidable (inedible) waste from the coffee consumption. As coffee production and beverage consumption are increasing worldwide, a more sustainable waste management is required since the usual disposal in landfill is a liability to both humans and the environment. This paper is aimed at showing a possible alternative reuse of coffee ground wastes in novel green building materials intended for thermo-plastering applications in construction, in a circular economy context. Coffee waste was used in various percentages (up to 17.5%) to assess the engineering performance of the produced bio-composite mortars. The …
