Indicators for Tourist Destinations: A General Assessment
2022
The assessment and monitoring of tourist destinations is now more than ever a prerogative of governments around the world. The contiguous situation caused by the outbreak of the COVID-19 pandemic is pushing local destinations to adopt new standards that have never been considered until now. In addition, the collapse of tourist demand and the partial recovery of tourist activities could, in the medium term, affect tourist flows, but more importantly the tourist supply, which still suffers from suppliers and producers damaged by the blockage of services and production. The work aims to provide a general assessment of sustainability and competitiveness indicators, describing the work carried o…
Linking bean-to-bar to sustainable entrepreneurship
2017
The increasing growth and recognition of bean-to-bar chocolate production have led to some people calling it a ”movement” or ”revolution”. The entrepreneurs championing bean-to-bar assert that their approach provides better and innovative services to both cocoa farmers (growers) and consumers. In essence, they are meaningfully contributing to the sustainable transformation of the cocoa industry. Furthermore, researchers agree that a concept that combines elements from both sustainability and entrepreneurship is called sustainable entrepreneurship. Therefore, are bean-to-bar chocolate producers sustainable entrepreneurs? In an attempt to answer this question, this thesis explores the links b…
Sustainability Development in Mathematics Education : A Case Study of What Kind of Meanings Do Prospective Class Teachers Find for the Mathematical S…
2019
In this article, our focus is on sustainable development in mathematics education from the point of view of teacher training. The aim was to develop prospective teachers’ content knowledge and pedagogical content knowledge of school mathematics. As a case study, we chose the mathematical symbol “a/b”, and examined how prospective class teachers in Finland connect it to the concepts of fraction, ratio, division, rational number or probability. Mathematics textbooks often have a central role in lessons, and they affect strongly how pupils understand concepts and the relationships between them. We chose languaging as a multi-semiotic approach to interpreting what kind of meanings the prospecti…
Is Environmental Sustainability Also “Economically Efficient”? The Case of the “SOStain” Certification for Sicilian Sparkling Wines
2022
The Italian wine industry is strongly committed to sustainability. Among the numerous sustainability certifications and programs implemented in Italy for the wine sector, SOStain is the oldest at the regional level. The SOStain Foundation promotes the voluntary application of a sustainability program, developed in 2010 in Sicily (Southern Italy). The requirements of the SOStain specifications are connected to the new CAP 2023–2027 objectives; therefore, companies preparing for the new challenges of future winemaking might be interested in joining the SOStain Foundation for greening production practices. The objective of this study was to learn producers’ and consumers’ opinions about motiva…
Quasi-Fractional Models of Human Tendons Hereditariness
2018
In this study, the authors, after collecting a series of experimental evidences following a creep and relaxation tendon campaign, propose a non-linear model of the viscoelastic behavior of the tendons. The ligaments investigated are the patellars and the hamstrings. The analytical model proposed by the authors aims to explain the non-linear hereditary behavior of these tissues and proposes an approach with which to develop a hereditary fractional-order non-linear model.
I musei naturalistici come presidi ambientali e culturali. L'Orto botanico di Palermo
2013
La funzione degli Orti botanici, fondamentalmente, si esplica nella conservazione, nella ricerca scientifica, nelle attività espositive ed educative. I punti di forza dell’azione sociale di questi tipi di musei deriva sia dalla capacità di produrre e diffondere la conoscenza scientifica, sia dalla ricchezza patrimoniale posseduta. Una serie di emergenze planetarie e le prospettive incerte per l’ambiente, le società, le economie di tutte le nazioni del mondo configurano lo scenario d’oggi. Questa situazione richiede la costruzione collettiva di nuove forme di sentire, pensare e agire nella ricerca di soluzione ai problemi contemporanei. Si tratta quindi, per i musei scientifici, di intrapren…
A comparative analysis of the sustainability of rice cultivation technologies using the analytic network process
2010
Sustainability of local farming systems and technologies is a very important issue that faces notorious measurement difficulties. Multi-criteria methods may help researchers to solve empirical problems in the construction of composite sustainability indicators and in ranking agricultural technologies according to their sustainability. This paper shows how a multi-criteria decision-making technique, the Analytic Network Process (ANP), can be fruitfully employed to this end. Contrary to simpler and hierarchical goal-criteria-alternative approaches, in ANP all the elements in the network can be related in any possible way, which means that a network can incorporate feedback and interdependent …
A New Simple Function for Combustion and Cyclic Variation Modeling in Supercharged Spark Ignition Engines
2022
Research in the field of Internal Combustion (IC) engines focuses on the drastic reduction of both pollutant and greenhouse gas emissions. A promising alternative to gasoline and diesel fuel is represented by the use of gaseous fuels, above all green hydrogen but also Natural Gas (NG). In previous works, the authors investigated the performance, efficiency, and emissions of a supercharged Spark Ignition (SI) engine fueled with mixtures of gasoline and natural gas; a detailed research involving the combustion process of this kind of fuel mixture has been previously performed and a lot of experimental data have been collected. Combustion modeling is a fundamental tool in the design and optimi…
Food community networks as sustainable self-organized collective action: A case study of a Solidarity Purchasing Group
2014
The spread of Food Community Networks (FCNs) is mainly due to new and confirmed policies for consumption, testing new social paradigms aimed at promoting sustainable development in rural areas through the active reorganization of the agricultural and food industry. As a result, there is a set of rules deriving from complex relational structures competing to define self-organized collective action for sustainability. This paper analyses the structure of relations within FCNs. With this end in view, research on the experience of FCNs has been done, in particular of Solidarity Purchasing Groups (henceforth SPGs) in Sicily (Southern Italy). By applying Social Network Analysis, the article ident…
