Promoting ecological citizenship: towards a conceptual framework

2007

Citizenship has been a hot topic of debate within the green literature since the 1990s. Concepts like ecological and environmental citizenship capture the linkage between green politics and theories of citizenship. Although a significant number of contributions to the meaning of ecological/environmental citizenship have been made, their practical implications remain under-theorized. With the purpose of addressing this gap, my paper explores the conditions necessary for ecological citizenship to flourish. While pointing to the connection between questions of meaning and promotion, I seek to move debates from discussions on the theoretical concept to the possibilities for its cultivation. Two…

Care and reunification in a Cape Verdean family: Changing articulations of family and legal ties

2018

This article looks at the interaction between transnational family relationships, on the one hand, and family-related immigration policies, on the other. Taking the conflicting concerns that arose between administrative decision-makers and family members during an attempt to reunite a Cape Verdean family spread across several countries as an example, the questions of what ‘family’ means, what relationships are included and the nature of the relationships involved answered differently by different actors will be shown. The article discusses the way in which the regulation of transnational mobility according to specific categories of eligibility is giving social ties a concrete legal form whi…

“Lugares que tienen una herida que sangra”: las geografías interiores de Fernando Valverde

2018

Fernando Valverde (Granada, 1980) reúne en 2016 su poesía completa hasta la fecha: Viento favorable (1997-2002), Razones para huir de una ciudad con frío (2004), Los ojos del pelícano (2010) y La insistencia del daño (2014). Analizamos aquí la constitución de una peculiar cartografía poética, que cumple un papel axial: conecta territorios y culturas bajo una misma matriz existencial, configurando una geografía interior basada en la apropiación subjetiva de ciudad y naturaleza. Esta conversión del ?lugar? en ?espacio practicado? (Michel De Certeau) se realiza aquí a través de dos dispositivos: el mapa y el viaje. Valverde pone en marcha su poesía con la metáfora del ?andar?: logra la apropia…

Characterization of ellipsoids through an overdetermined boundary value problem of Monge–Ampère type

2014

Abstract The study of the optimal constant in an Hessian-type Sobolev inequality leads to a fully nonlinear boundary value problem, overdetermined with non-standard boundary conditions. We show that all the solutions have ellipsoidal symmetry. In the proof we use the maximum principle applied to a suitable auxiliary function in conjunction with an entropy estimate from affine curvature flow.

SCELTA E APPLICAZIONE DI NUOVI STANDARD DI MANOVRA NELLE FASI DI DECOLLO ED ATTERRAGGIO DELL’ELICOTTERO - MODELLO E SPERIMENTAZIONE -

Una zona o un ambiente ha tipicamente un livello sonoro che lo caratterizza e ci si aspetta che le variazioni di quell’ambiente in equilibrio dovute ad un evento acustico insolito alterino le sensazioni delle persone in quel contesto. Non ci si può riferire al buon senso per valutare se disturbiamo o danneggiamo il prossimo, è necessario individuare le fonti di rumore e valutare l’impatto ambientale tramite indagini di tipo qualitativo e fasi sperimentali di misura. Lo studio condotto ha correlato il dato qualitativo a quello quantitativo sia in ambito predittivo che tramite rilievi sul campo. Gli scopi e gli obiettivi sono incentrati a: ricercare una simulazione coerente di propagazione de…

CONNESSIONI ECOLOGICO-FUNZIONALI NEGLI STRUMENTI DI PIANIFICAZIONE: IL CASO DI VITORIA-GASTEIZ IN SPAGNA

2019

L’articolo si propone di indagare il tema delle connessioni ecologico-funzionali sotto il profilo del riconoscimento normativo all’interno degli strumenti di pianificazione. La questione, non adeguatamente affrontata dalla letteratura scientifica di riferimento in tema di reti ecologiche, diviene di nodale rilevanza nel processo di radicamento dei modelli ecologico-reticolari nei dispositivi che regolano le trasformazioni dell’uso del suolo. Il caso di Vitoria-Gasteiz, capoluogo del Pais Vasco in Spagna, appare significativo in tal senso in quanto, in seno ad un lungo percorso di costruzione del suo Anillo verde all’interno del piano urbanistico, riconosce sotto il profilo regolativo tali e…

Tourism SME sustainability social and economic challenges during pandemic: cases of Russian Federation, Georgia and Latvia

2021

Until 2020, the tourism industry was characterized by a growth rate, the statistics highlight that globally 2019 was the tenth year with a consecutive annual growth. However, the Covid-19 pandemic marked a major turning point in the development of tourism, instead of tourism overdevelopment, the underdevelopment issues appeared in front pages of the industry news. The effects of the pandemic are intensified by the fact that tourism is a labour-intensive industry and that most companies in the sector are SMEs (small and medium sized enterprises). At this time, it is crucially important to look at sustainability issues, therefore the aim of this study is to analyse the social and economic dim…

Ciencia de la sostenibilidad: un nuevo campo de conocimientos al que la química y la educación química están contribuyendo

2013

Los dominios de conocimiento más diversos contribuyen actualmente al tratamiento de problemas socioambientales. Se han publicado muchos artículos y libros en los campos de Química Verde, Ecología Industrial, Ingeniería Ambiental, Economía Verde (baja en carbono), Educación Ambiental, etc. Pero hace poco se entendió que estas contribuciones son insuficientes y que necesitamos una Ciencia de Sostenibilidad que los integra a todos. Este documento estudia el surgimiento de este nuevo campo de conocimiento e investigación, cuyo objetivo explícito es contribuir a la transición a una sociedad sostenible. The most diverse knowledge domains are currently contributing to the treatment of socio-enviro…

nuevos desafíos en espectroscopia vibracional

2017

El principal objetivo de la Química Analítica Verde es la sustitución de metodologías contaminantes por otras más limpias, mediante:  La reducción de reactivos y disolventes empleados en el pre-tratamiento y análisis de las muestras.  Minimizar las cantidades y de la toxicidad de los compuestos empleados en las etapas de preparación y medida, especialmente mediante automatización y miniaturización.  El desarrollo de metodologías directas de análisis sin uso de reactivos o disolventes y que, por tanto, no generen desechos tóxicos ni peligrosos. Las técnicas espectroscópicas junto con el uso de la quimiometría pueden ser una buena alternativa a los métodos tradicionales, ya que se pueden r…

PALERMO SICILIAN GARDEN

2019

Palermo, città-giardino fin dalle sue origini, ha fatto del verde una delle sue espressioni più manifeste. La città conserva come in un scrigno le testimonianze più significative della storia del verde che occupa un ruolo determinante dal punto di vista ambientale, storico e paesaggistico. Agli splendidi parchi della Conca d'Oro che un tempo abbracciavano la città, fanno eco i meravigliosi giardini privati nascosti all’interno di palazzi nobiliari, chiese e monasteri e i parchi e le ville pubbliche, alcuni dei quali trasformati oggi in spazi di verde attrezzato e orti urbani. Il contributo espone gli esiti di uno studio condotto presso il Dipartimento di Architettura dell'Università di Pale…
