IPM-recommended insecticides harm beneficial insects through contaminated honeydew

2020

The use of some systemic insecticides has been banned in Europe because they are toxic to beneficial insects when these feed on nectar. A recent study shows that systemic insecticides can also kill beneficial insects when they feed on honeydew. Honeydew is the sugar-rich excretion of hemipterans and is the most abundant carbohydrate source for beneficial insects such as pollinators and biological control agents in agroecosystems. Here, we investigated whether the toxicity of contaminated honeydew depends on i) the hemipteran species that excretes the honeydew; ii) the active ingredient, and iii) the beneficial insect that feeds on it. HPLC-MS/MS analyses demonstrated that the systemic insec…

A Task Execution Scheme for Dew Computing with State-of-the-Art Smartphones

2021

The computing resources of today’s smartphones are underutilized most of the time. Using these resources could be highly beneficial in edge computing and fog computing contexts, for example, to support urban services for citizens. However, new challenges, especially regarding job scheduling, arise. Smartphones may form ad hoc networks, but individual devices highly differ in computational capabilities and (tolerable) energy usage. We take into account these particularities to validate a task execution scheme that relies on the computing power that clusters of mobile devices could provide. In this paper, we expand the study of several practical heuristics for job scheduling including executi…

La scuola e la società in John Dewey ai tempi della pandemia da Covid-19

2022

La pedagogia di John Dewey può essere oggi intesa come una risorsa utile per fronteggiare il periodo complesso e drammatico caratterizzato dalla pandemia da Covid-19. È per questo motivo che il contributo, attraverso alcuni riferimenti alle opere più significative della prospettiva deweyana, intende riflettere sull’attualità del pensiero deweyano, facendo un esplicito riferimento alla sulla sua idea di democrazia come a way of life e ponendo in risalto in che modo le scuole possano contribuire a fronteggiare circostanze complesse come quelle attuali, progettando e realizzando dei processi educativi mirati alla trasmissione e alla sperimentazione dei principi democratici e alla formazione di…

La scuola al servizio della democrazia: i princìpi ispiratori di John Dewey per l’interpretazione di Lamberto Borghi

2021

John Dewey ha dedicato molta attenzione al rapporto scuola-società, affermando come il modo di insegnare e di educare potesse favorire la creazione di una democrazia intesa non come un mero sistema politico, bensì come un a way of life. In tal senso, il contributo cha lo scopo di evidenziare come l’idea di Dewey di una scuola a servizio della democrazia si sia diffusa anche in Italia grazie al contributo di Lamberto Borghi. Quest’ultimo, nell’immediato secondo dopoguerra e attraverso l'influenza del pensiero di John Dewey, teorizzò infatti un’educazione volta allo sviluppo di una personalità comunitaria in grado di vivere in un contesto democratico nel pieno rispetto di ogni forma di divers…

L'educazione intellettuale: il rapporto fra docenti e discenti nell'ottica di John Dewey

2019

Attraverso alcune letture di John Dewey, il presente articolo presenterà l’idea di una relazione educativa incentrata sull’equilibrio tra docente e alunno e su un processo educativo finalizzato alla crescita intellettuale e all’avvenimento personale Inoltre, si rifletterà sull’importanza di realizzare tutto questo nelle attuali società tardo-moderne, nelle quali imparare a pensare rappresenta un’emergenza educativa impossibile da trascurare. Through some readings by John Dewey, this article will present the idea of an educational relationship focused on the balance between teacher and student on an educational process aimed at intellectual growth and at personal event. In addition, it will …

Il valore educativo dell’esperienza in John Dewey

2020

Uno dei principi cardine del pensiero di John Dewey è sicuramente quello di esperienza reputata generatrice di crescita e di formazione per ciascun individuo. Pertanto, questo contributo si propone come scopo quello di illustrare dapprima alcune opere della giovinezza, nelle quali Dewey, con un riferimento chiaro ed evidente a Immanuel Kant, ha maturato l’idea di un’esperienza produttrice di conoscenza e di maturazione umana e sociale; in un secondo momento verranno illustrati alcuni scritti della maturità, dove è possibile rintracciare un’evoluzione del concetto di esperienza, alla quale Dewey ha attribuito un valore educativo che doveva essere incoraggiato nei contesti scolastici del suo …

I luoghi dove realizzare il “nuovo individualismo” di John Dewey: il ruolo del metodo scientifico e della pratica educativa del riconoscimento

2021

This contribution aims to reflect on the concept of individualism as presented by John Dewey who used this word to indicate the unique and unrepeatable part of man, differentiating the “old individualism” from the “new individualism”. Taking into consideration the Deweyan theories of the first half of the twentieth century, with particular reference to the 1930 writing The Individualism Old and New, it is noted that Dewey criticized the existence of an “old individualism” intended as an emblem of egocentrism and of asociality, the causes of which were traceable to the advent of industrialization, social stratification and capitalism. According to him, these were people without a solid ident…

THE SCHOOL AT THE SERVICE OF THE SOCIETY: CONSEQUENCES FOR THE "NEW WORLD"

2022

Introduction In this article I shall seek to demonstrate the remarkable contemporary relevance of John Dewey’s pedagogic ideas, found in publications such as My Pedagogic Creed, The School and Society and Democracy and Education. Through a brief analysis of these works I will highlight how much Dewey believed in a school that is connected to society and which places itself at its service, contributing to the birth or consolidation of a democracy understood not just as a form of government, but as a way of life. In view of this analysis and in light of the present pandemic caused by COVID-19, I will consider the importance today of the school. Following Dewey, I will take into account the ro…

AbstractIn this article we examine first-year student teachers’ possibilities to become interested in professional issues in teacher education. We study the phenomenon of becoming interested among first-year student teachers via three different kinds of data. We analysed our data through John Dewey’s definition of interest, where a person has an interest if s/he is actively keen on some object that has personal meaning for her/him. According to our data, student teachers adopt an object of interest that teacher educators provide. Learners found it difficult to find the objects of interests by themselves, and it was exceptional for them to find personal meaning and an active state of interes…
