Consumption and production patterns for agricultural sustainable development
No full textAgriculture has always played a key role in feeding the world population and ensuring
the development of sustainable food production systems.
However, over recent decades, many farmers have over-exploited agricultural ecosystems
in order to increase their production and incomes. This has caused a reduction or
degradation of environmental sustainability, reducing farmers’ profitability and leading
many producers to abandon rural areas. Moreover, currently, over 820 million people in
the world are hungry, while a third of the food produced is lost or wasted, with negative
implications on economic, social and environmental conditions at a global level, highlighting
how different production, educational campaigns and consumption approaches are
needed. In this context, the 2030 Agenda for Sustainable Development aims at eradicating
poverty in all its forms and dimensions, by ensuring an economic, environmental and social
sustainable development. In particular, every country by 2030 should allocate public
and private financial resources to develop and carry out relevant strategies and programs,
by means of 17 sustainable development goals. One of them is represented by “ensuring
sustainable consumption and production patterns” in agriculture that, in addition to
feeding the world population, should ensure both the development of sustainable food
production systems and promote responsible consumption by consumers. According to
the Agenda, in fact, the sustainable cropping systems, on the one hand, have to increase
productivity and production, but on the other, they should reduce the negative social and
environmental impacts, thanks also to a sustainable changes in consumers’ choices.
Therefore, the aim of this Special Issue has been to collect scientific studies worldwide
dealing with the two main topics of the “ensuring sustainable consumption and production
patterns” goal: (1) the adoption of sustainable production patterns in the agriculture sector;
(2) the study of consumers’ behavior towards sustainable food products. This Special Issue
contains 13 papers that have tried to enrich the literature on agricultural sustainable development,
taking into consideration at least one of its three dimensions: the environmental,
social and economic dimensions

Concentrazione delle tensioni dovuta a disallineamento assiale nei giunti testa a testa
No full textNel presente lavoro viene eseguita una approfondita analisi numerica per analizzare il comportamento a fatica di giunzioni saldate testa a testa con disallineamento assiale. La procedura di calcolo è basata sul metodo del gradiente implicito attuata con le stesse modalità proposte in precedenza per lo studio delle giunzioni saldate ad arco. Viene presentata un’analisi di tipo parametrico al variare dell’entità del disallineamento assiale nella giunzione fornendo dei diagrammi di sintesi utili per il calcolo della resistenza a fatica. Infine, è stato eseguito un confronto con dati sperimentali tratti dalla letteratura di provini saldati testa a testa sollecitati a fatica e caratterizzati da tre diversi livelli di disallineamento assiale. I dati sperimentali sono relativi a provini in acciaio S1100.This paper reports a detailed numerical analysis of the fatigue strength of butt-welded joints with axial misalignment by applying the implicit gradient method. The numerical procedure is implemented similarly to a previous proposed investigation on the arc welded joints. A parametric analysis is proposed by changing misalignment type and quantity and providing some diagrams useful for the fatigue strength assessment. Finally, the paper shows an experimental comparison between the numerical assessment and the experimental fatigue data taken from the literature. The experimental data are some fatigue tests on welded joints made of steel S1100 and characterized by three different levels of axial misalignment
Fécondité envisagée, fécondité réalisée : un lien complexe
No full textDes enquêtes sont menées régulièrement pour savoir si les personnes souhaitent avoir des enfants dans l’avenir. Peut-on se fier à leurs réponses pour prévoir les naissances de demain ? Si leurs désirs ne se réalisent pas, d’où cela vient-il ? Des difficultés à anticiper l’avenir ? Des imprévus de la vie - décès du conjoint, divorce, chômage - qui empêchent la réalisation des projets ou les repoussent à plus tard ? Laurent Toulemon et Maria Rita Testa nous livrent les résultats de la dernière enquête menée en France sur le sujet

Intersubjetividade, natureza e sentimentos morais. A teoria crítica de A. Honneth e a regra de ouro
No full textThe text raises the question of the conditions for the possibility of intersubjectivity in the theory of recognition. An analysis of the theory of recognition formulated by Axel Honneth shows how the conflict determined by moral motivations relativizes the Habermasian premise of the linguistic understanding and brings the normative dimension back to social theory. The author returns to the pages of the Encyclopedia of Hegel to recover the objective dimension of intersubjectivity and highlights problems in Honneth’s theoretical project. He confronts both the linguistic-hermeneutic and the recognition paradigm with his pressuposition of this intersubjectivity that yet have to be established, and concludes that the theory of recognition can not explain the normative basis of intersubjectiv recognition. This theory, so Testa, describes contexts of interaction and not moral imperatives. The golden rule, especially his negative formulation is seen as a better codification of the requirement to give recognition without neglecting the experience of offenses and fight; it is seen as a better positive justification of the norms of reciprocity.O texto coloca a questão das condições de possibilidade da intersubjetividade na teoria do reconhecimento. Uma análise da teoria do reconhecimento formulada por Axel Honneth mostra como o conflito determinado por motivações morais relativiza o postulado Habermasiano do entendimento lingüístico e traz de volta a dimensão normativa à teoria social. O autor faz um retorno às páginas da Enciclopédia de Hegel para recuperar a dimensão objetiva da intersubjetividade e destacar problemas teóricos no projeto de Honneth. Com isso passa a confrontar tanto o paradigma lingüísticohermenêutico como o do reconhecimento com o fato de pressuporem a intersubjetividade a ser ainda constituída, para concluir que a teoria do reconhecimento não consegue explicitar um núcleo normativo do reconhecimento intersubjetivo; ela descreve contextos de interação e não imperativos morais. A da regra de ouro, em especial na formulação negativa (“não faças a ninguém aquilo que não gostarias que fosse feito a ti – Tb 4,15) é vista como melhor codificação da exigência de reconhecimento sem prescindir da experiência da ofensa e da luta, como melhor justificação positiva das normas de reciprocidade.
