The present contribution proposes a decision support paradigm that elucidates factors ensuing from Product-Service System implementations and that might be neglected due to assessment difficulties. These aspects emerge when companies are exposed to new business model scenarios underlying servitized propositions.

Shifts in government priorities in response to the 2007 global recession have affected wildfire management and natural disaster funding arrangements, leading to a reduced effectiveness of fire suppression actions and increasing fire vulnerability. Our study investigates the role of local socioeconomic contexts on fire suppression effectiveness under economic expansion and recession in a Mediterranean region (Attica, Greece) strongly affected by 2007 crisis and displaying a persistently high density of peri-urban wildfires.

Biodiversity loss is a widely debated world problem, with huge economic, social, and environmentally negative consequences. Despite the relevance of this issue, the psychological determinants of committed action towards nature and biodiversity have rarely been investigated. This study aims at identifying a comprehensive social-psychological profile of activists committed to biodiversity protection and at understanding what determinants best predict their activism.

This paper proposes an enterprise input-output model to assess the impacts created by industrial symbiosis (IS) on traditional supply chains for production inputs, triggered by resource use change. The model is capable of measuring a variety of sustainability indicators such as resource and waste savings, total energy use reduction, employment creation, reduction in greenhouse gas emissions. Furthermore, the model can be used to analyze IS exchanges from a dynamic perspective, since it is able to take into account dynamic scenarios in wastes production and inputs requirement.

This paper proposes a systematic literature review concerning the implementation of industrial symbiosis (IS) within urban areas, a concept that has been defined by the literature as "urban symbiosis" and "urban-industrial symbiosis", indifferently. 26 papers published between 2009 and 2018 are analyzed. This review is aimed at highlighting: (1) the specific research goals addressed; (2) the IS synergies currently implemented within urban areas; and (3) barriers and enablers to the implementation of IS within urban areas. Suggestions for future research are also proposed.

This paper contributes to green product development by identifying the green products with the highest potential for growth in a country. To address our aim, we use the concept of product proximity and product space and, borrowing from the results of recent studies on complexity economics, we advance that the green products with the highest potential for growth among all green products in a given country are those being in close proximity to the products a country produces with high Relative Comparative Advantage (RCA). We test this hypothesis performing a regression analysis.

Do agglomeration externalities affect firm survival? Regional Studies. This paper analyses the impact of spatial
agglomeration externalities on Italian start-up firms’ survival. Italy represents a relevant case study given the wellknown
role of firm clusters in the country’s economic development. Results obtained support the hypothesis that
industry variety reduces the likelihood of firm exit. Specifically, related variety, which contributes to the generation

The biomass burning marker levoglucosan is produced via combustion of woody cellulose at temperature over 300 °C, and is hence widely used to trace fires or discriminate urban air pollution sources. In this context, it is very useful the availability of a standard reference material (SRM) with a certified value of levoglucosan, to check the quality, reliability and accuracy of the measurements.

As rates of global warming increase rapidly, identifying species at risk of decline dueto climate impacts and the factors affecting this risk have become key challenges inecology and conservation biology. Here, we present a framework for assessing threecomponents of climate-related risk for species: vulnerability, exposure and hazard.We used the relationship between the observed response of species to climatechange and a set of intrinsic traits (e.g. weaning age) and extrinsic factors (e.g.

A key question in biology is to understand how interspecies morphological diversities originate. Plant roots present a huge interspecific phenotypical variability, mostly because roots largely contribute to adaptation to different kinds of soils. One example is the interspecific cortex layer number variability, spanning from one to several.
