A heuristic fuzzy algorithm for assessing and managing tourism sustainability

2019

“Smartness” and “sustainability” are gaining growing attention from both practitioners and policy makers. “Smartness” and “sustainability” assessments are of crucial importance for directing, in a systemic perspective, the decision-making process toward sustainability and smart growth objectives. Sustainability assessment is a major challenge due to the multidisciplinary aspects involved that make the evaluation process complex and hinder the effectiveness of available monitoring tools. To achieve the assessment objective, we introduce an enhanced fuzzy logic-based framework for handling the inherent uncertainty and vagueness of the involved variables: we apply our approach to Italy, and we…

Assessing the carbon footprint across the supply chain: Cow milk vs soy drink

2022

Abstract Since livestock product consumption could have a significant effect on tackling climate change, in the few last years, there has been an increasing consumer demand for non-dairy alternatives. Despite plant-based beverages being considered crucial to foster the transition towards sustainable diet models, no studies have yet compared the level of emissions of plant-based beverages with animal-based ones. The present study aims at computing the carbon footprint of cow milk and that of soy drink and evaluating the carbon footprint results in the light of the substitutability of cow's milk with soy drink, analyzing the potential environmental, economic and nutritional trade-offs between…

Body forces and thermoelasticity in the SGBEM

2003

This paper proposes a revisiting of the displacement method performed through a domain substructuring into macro-zones named BelementsThis paper proposes a revisiting of the displacement method performed through a domain substructuring into macro-zones named Belements in the ambit of the Symmetric Galerkin Boundary Element Method. The external actions are the boundary forces and the constraint subsidings, as well as the body forces b and the anelastic strains ϑ . In order better to connect the method to the boundary geometry of each B-element the volume integrals of b and ϑ are transformed into line integrals in the discretized B-elements. The KARNAK sGbem program is utilized for some examp…

Measuring wage discrimination according to an expected utility approach

2012

Following on from the seminal works by Blinder (1973) and Oaxaca (1973), many methods have been proposed to measure wage discrimination against women. Some of these methods focus on the entire distribution of the discrimination experienced by each woman, underlining a common aspect of poverty and discrimination analysis: the latter two are both based on an idea of deprivation which originates from a poverty line (in the case of poverty) and from the expected wage in the absence of discrimination (in the case of wage discrimination) (Jenkins, 1994; Del Río et al., 2011). These approaches hinge on conditional-to-individual-characteristics expected wages, lacking in any focus regarding the ent…

Stability analysis of Beck's column over a fractional-order hereditary foundation

2018

This paper considers the case of Beck's column resting on a hereditary bed of independent springpots. The springpot possesses an intermediate rheological behaviour among linear spring and linear dashpot. It is defined by means of couple ( C β ,  β ) that characterize the material of the element and is ruled by a Caputo's fractional derivative. In this paper, we investigate the critical load of the column under the action of a follower load by means of a novel complex transform that allows to use the Routh–Hurwitz theorem in the complex half-plane for the stability analysis.

Habitat preferences of edible dormouse, Glis glis italicus: implications for the management of arboreal mammals in Mediterranean forests

2015

Research on arboreal mammals living in Mediterranean forests is poor. Molecular research assessed the existence of an evolutionary significant unit in the edible dormouse populations living in south Italy, Sicily and Sardinia, and we decided to investigate the environmental factors capable of explaining its occurrence and abundance in Sicily, for a better management of these populations. We assessed the species habitat preferences by setting 25 large and 25 small nestboxes in five sample areas along an altitudinal gradient of the Madonie Range, and recorded habitat variables, food availability, and demographic data for two years. To obtain synthetic descriptors of the dormice habitat requir…

A methodological comparison of head-cut based gully erosion susceptibility models

2020

Abstract A GIS-based hybrid approach for gully erosion susceptibility mapping (GESM) in the Biarjamand watershed in Iran is presented. A database comprised of 15 geo-environmental factors (GEFs) was compiled and used to predict the spatial distribution of 358 gully locations; 70% (251) of which were extracted for training and 30% (107) for validation. A Dempster-Shafer (DS) statistical model was employed to map susceptibility. Next, the results of four kernels (binary logistic, reg logistic, binary logitraw, and reg linear) of a boosted regression tree (BRT) model were combined to increase the efficiency and accuracy of the mapping. Area under receiver operating characteristics (AUROC), tru…

Wenker, Georg (1852–1911)

2006

Georg Wenker (1852–1911) was the founder of a) dialect cartography and b) of the ‘indirect method’ in dialectology. From the very beginning (1877), his maps were empirically based on some 40 Standard German sentences, the so-called 40 ‘Wenker sentences,’ composed under prestructural aspects with regard to the historical grammar and, consequently, to the structural approach to dialects in the Kleiner Deutscher Sprachatlas (see Veith et al., 1984–1999). Their translation into local dialects was done by public school children assisted; their teachers assisted them and wrote the translations down (‘indirect method’). This method of exploring was different from the direct method used, e.g., for …

Fringed Life Satisfaction? A Life-Course Perspective on the Impact of International Migration on Subjective Well-Being

2018

This chapter investigates the role of personal life events in changing levels of life satisfaction and tries to contrast migrants to native population in this respect. Marriage, divorce, separation, widowhood, and having children are considered as potential triggers for differential transformations of migrant lives as compared to non-migrant. The main assumption relies on the increased uncertainty and destandardization of migrant life course, given their spatial mobility that disrupts stages of traditional life cycle. The findings from the panel data obtained from German Socio-Economic Panel (GSOEP; Germany), collected during more than three decades, reveal higher sensitivity of migrants to…
