Life cycle assessment of low temperature asphalt mixtures for road pavement surfaces: A comparative analysis
2018
The increasing fuel consumption demand, the accelerated pressure imposed by the depletion of 5 scarce raw materials and the urgent environmental protection requirements are forcing the change of 6 pavement industry and academia community’s research endeavors towards the development of low 7 emissions road paving technologies able to significantly reduce mixing and compaction temperature as 8 well as the consumption of virgin raw materials. One set of relatively recent technologies in the field of 9 pavement materials that aims at addressing those concerns are the warm mix asphalt (WMA). In fact, 10 they have the potential to allow the reduction of energy consumption and airborne emissions d…
The land grabbing in the international scenario: the role of the EU in land grabbing
2016
The worldwide increase in population and consumption has produced a growing demand for food and energy in the rich and developing Countries. The resulting intensification of land investments, to cope with this need, has in many cases produced investments without transparency rules and it hasn't created real development for local people. The aim of this paper is to identify, through a cluster analysis, homogeneous groups of investor Countries in order to understand the role of the EU Member States in the context of land grabbing. The results show that the strategies adopted by the investors are driven by the need to achieve energy security and reduce CO2 emissions in order to cope with the p…
Adapting to High Temperatures: Effect of Farm Practices and Their Adoption Duration on Total Value of Crop Production in Uganda
2021
In this article, we use spatially granular climate data merged with four waves of household survey data in Uganda to examine empirically the relationships among high temperatures, total value of crop production, and the adoption and adoption duration of two sustainable agricultural practices (organic fertilizer adoption and maize–legume intercropping). We do this using a fixed-effect model with instrumental variables to address potential endogeneity issues. Our findings indicate that the adoption of these practices has a positive effect on the total value of crop production, and such effect increases monotonically as temperatures increase from long-term averages. Moreover, the number of yea…
How alternative food networks work in a metropolitan area? An analysis of Solidarity Purchase Groups in Northern Italy
2019
AbstractOur paper focuses on Solidarity Purchase Group (SPG) participants located in a highly urbanized area, with the aim to investigate the main motivations underlining their participation in a SPG and provide a characterization of them. To this end, we carried out a survey of 795 participants involved in 125 SPGs in the metropolitan area of Milan (Italy). Taking advantage of a questionnaire with 39 questions, we run a factor analysis and a two-step cluster analysis to identify different profiles of SPG participants. Our results show that the system of values animating metropolitan SPG practitioners does not fully conform to that traditionally attributed to an alternative food network (AF…
An intertemporal approach to measuring environmental performance with directional distance functions: Greenhouse gas emissions in the European Union
2014
Abstract The impact of economic activity on the environment is a matter of growing concern for firm managers, policymakers, researchers and society as a whole. Building on previous work by Kortelainen (2008) [Dynamic environmental performance analysis: A Malmquist index approach. Ecological Economics 64, 701–715], we contribute an approach to assessing intertemporal environmental performance at the level of the management of specific pollutants, as the result of change in eco-efficiency and environmental technical change, which identify catching-up with best available environmental practices and eco-innovation, respectively. In doing so, we use Data Envelopment Analysis techniques, directio…
The determinants of social sustainability in work integration social enterprises: the effect of entrepreneurship
2021
Work integration social enterprises (WISEs) exist to fight poverty and social exclusion. They offer support and guidance to those at risk of exclusion to help these individuals join the labour market. This study examines the relationship between social enterprises (specifically, work integration social enterprises) and their social impact, considered here in the form of social sustainability. This article presents the results of empirical analysis of 62 Spanish work integration social enterprises using fuzzy-set qualitative comparative analysis. The article focuses on the entrepreneurial characteristics of the companies’ founders and managers as drivers of social value creation. Specificall…
Higher education in the fight against poverty from the capabilities approach: The case of Spain
2017
Abstract This article describes relative poverty in Spain in relation to the other States in the European Union, following the European indicator AROPE. The official data provided by the National Statistical Institute of Spain and by Eurostat, refer to the year 2014 (the last one for which definitive data are available is 2015). Given the relative poverty of Spanish population, the failure of conventional economic theories, which conceive social development as GDP growth, is clear, and it is argued in favour of the human capabilities approach as a more adequate option for development, from a theoretical-practical point of view, for the reduction and/or eradication of poverty, as well as the…
A systematic assessment of road pavement sustainability through a review of rating tools
2017
Pavements are engineered systems present in every modern society, and they have significant environmental, economic and social impacts. In an effort to promote more sustainable decisions regarding pavement design, construction and management, several pavement sustainability assessment tools have been developed. This research reviewed some of these tools and found that many of them do not treat the pavement as a system; instead, they seek to optimize individual aspects of the pavement in an effort to increase its sustainability. Therefore, a framework for analytically assessing the system outcomes towards sustainable objectives is presented and applied for modern pavement sustainability asse…
Lo sviluppo sostenibile della pesca nella marineria di Mazara del Vallo
2011
In a place like Sicily, where sea fishing and port activities are part of the territory, history and culture, fishery has always been vital to man and, for this reason, today it must be studied, protected and helped in the difficult transition towards long-term sustainability. Fishing is a driving sector for Mazara economy both for number of working days during the fishing season, and for industrial activities operating around this field (transformation, packaging, and distribution). A micro-economic analysis was carried on a sample of fishing enterprises in order to analyze the problems of the here studied seamanship. The analysis is based on the employers’ interviews. The collected data h…
Los grupos de interés en las entidades de crédito Españolas
2012
RESUMENSe plantean los orígenes, evolución y clasificación de los grupos de interés (stakeholders). Se pone de relieve la relación que se entabla entre la entidad de crédito como organización social y sus diferentes grupos de interés, analizándose la importancia que se asigna a estos.El trabajo de campo se realizó a través de una encuesta contestada por 57 entidades de crédito españolas. Los resultados del estudio muestran la sensibilidad de las entidades de crédito hacia la RSE (Responsabilidad Social de la Empresa), con referencia al conjunto del sector financiero español. Nuestro objetivo es analizar la importancia que tienen los diversos grupos de interés: accionistas, empleados, client…
