Corporate responsibility in the food chain: The criteria and indicators
2012
Corporate responsibility (CR) is becoming a key issue in the food chain. In order to make sense of this phenomenon, a seminal aper by Maloni and Brown (2006) called for further empirical investigation on the criteria of responsibility in the food supply chain. The purpose of this paper is to answer the call by identifying the criteria for defining CR and develop indicators for measuring the responsibility performance of the food chain. The study was based on interactive and participatory stakeholder dialogues with diverse experts, corporate representatives and other stakeholders, including non-governmental organizations (NGOs) and governmental bodies. Through an iterative research process w…
Ryhmäajattelu opiskelijaryhmän tapana vältellä ristiriitoja
2015
Tutkimuksessa tarkastellaan opiskelijaryhmän työskentelyä ryhmän kirjoittamien pöy-täkirjojen sekä tutkijoiden omien kokemusten pohjalta. Huomiota kiinnitetään erityisesti ryhmän tiedostamattomaan puoleen, pyrkimyksenä löytää merkityksiä ryhmän toiminnalle ja tätä kautta selityksiä, miksi ryhmän on ollut vaikea toimia perustehtävänsä mukaisesti. Tutkimus keskittyy tarkastelemaan ryhmän toimintaa psykodynaamisen ryhmäajatteluteorian pohjalta. Tutkimuskohteena on Jyväskylän yliopiston opettajankoulutuslaitoksessa vuonna 2009 aloittanut integraatioryhmä, johon myös tutkijat itse ovat kuuluneet. Aineisto koostuu integraatioryhmän pöytäkirjoista, jotka on kirjoitettu opiskelijoiden kolmen ensimm…
The chemical composition of the aerial parts essential oil of Ammi crinitum Guss. (Apiaceae) endemic of Sicily (Italy)
2022
Ammi L. is a small genus of economically important plants belonging to Apiaceae family that includes only six taxa. In the present study the chemical composition of the essential oil from aerial parts of Ammi crinitum Guss., a very rare plant, endemic of Sicily, was analyzed by GC–MS. No previously paper has been published on this species. The results showed the presence of large quantity of monoterpene hydrocarbons with sabinene (63.9%), as the most abundant component. Other metabolites present in good quantity were γ-terpinene (8.0%), and 4-terpineol (3.7%). Based on the composition of the essential oil of all the other Ammi taxa, several considerations have been carried out.
Improving the Downwind Sail Design Process by Means of a Novel FSI Approach
2021
The process of designing a sail can be a challenging task because of the difficulties in predicting the real aerodynamic performance. This is especially true in the case of downwind sails, where the evaluation of the real shapes and aerodynamic forces can be very complex because of turbulent and detached flows and the high-deformable behavior of structures. Of course, numerical methods are very useful and reliable tools to investigate sail performances, and their use, also as a result of the exponential growth of computational resources at a very low cost, is spreading more and more, even in not highly competitive fields. This paper presents a new methodology to support sail designers in ev…
Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy)
2012
Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy), using multivariate geostatistical techniques and a set of topographical, phy…
Experimental Observation of a Large Low-Frequency Band Gap in a Polymer Waveguide
2018
The quest for large and low-frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration control, and to seismic wave abatement. For this purpose, a plethora of complex architectures (including multiphase materials) and multiphysics approaches have been proposed in the past, often involving difficulties in their practical realization. To address the issue of proposing a material design that enables large band gaps using a simple configuration, in this study we propose an easy-to-manufacture design able to open large, low-frequency complete Lamb band gaps exploiting a suitable arrangement of masses and stif…
La collaborazione scuola-università nella formazione dei futuri maestri. Una ricerca svolta presso il corso di laurea magistrale in Scienze della For…
2017
La collaborazione tra la scuola e l'università nella formazione iniziale degli insegnanti di scuola primaria e dell'infanzia si esplica principalmente attraverso il tirocinio e i laboratori, dove si creano anche delle occasioni propizie per impostare e svolgere insieme delle ricerche in campo didattico. Un'attività di ricerca, promossa autonomamente dall'università, dovrebbe affiancare la sua azione formativa per verificarne periodicamente l'efficacia, ogni volta che vengono introdotte delle innovazioni significative. In questo breve intervento, si riportano i primi risultati della quarta ricerca svolta negli ultimi dodici anni sull'efficacia formativa del corso di studi in Scienze della Fo…
Girls4STEM: Gender Diversity in STEM for a Sustainable Future
2020
Science, Technology, Engineering, and Mathematics (STEM) are key disciplines towards tackling the challenges related to the Sustainable Development Goals. However, evidence shows that women are enrolling in these disciplines in a smaller percentage than men, especially in Engineering related fields. As stated by the United Nations Women section, increasing the number of women studying and working in STEM fields is fundamental towards achieving better solutions to the global challenges, since the potential for innovation is larger. In this paper, we present the Girls4STEM project, which started in 2019 at the Escola Tè
Habit and physical activity: Theoretical advances, practical implications, and agenda for future research
2019
Abstract Objective Understanding habits may inform intervention development aimed at promoting physical activity maintenance for long-term health. In the present article, I review theory and research on habits applied to physical activity. I provide an overview of contemporary conceptualizations of habit and habit theory; address whether or not physical activity can be habitual; review perspectives on how physical activity habits develop; summarize research on effects of physical activity habits; identify intervention strategies effective in promoting physical activity habits; and propose an agenda for future research on physical activity habits. Design and Methods Conceptual and narrative …
