On the use of composite indicators for mobile communications network management in smart sustainable cities
2020
Beyond 5G networks will be fundamental towards enabling sustainable mobile communication networks. One of the most challenging scenarios will be met in ultra-dense networks that are deployed in densely populated areas. In this particular case, mobile network operators should benefit from new assessment metrics and data science tools to ensure an effective management of their networks. In fact, incorporating architectures allowing a cognitive network management framework could simplify processes and enhance the network&rsquo
Building Resilient Smart Cities for Sustainable Urban Tourism in Africa Post-COVID-19 Pandemic
2022
AbstractThis paper contributes to the knowledge by examining the role of smart tourism technologies in destination resilience amidst the COVID-19 pandemic. Considering tourism in the COVID-19 crisis as an emerging stream of research, the study also explores how African cities deployed smart tourism technologies and how effective it has been in creating resilient and safe destinations. Data were collected through a semi-structured online interview from destination managers in Ghana, Kenya, and South Africa. The findings pose critical lessons for city destinations and how they need to transition into smartness to create safe spaces for travellers during and post-COVID-19. Our study makes nove…
Global urban environmental change drives adaptation in white clover
2022
Made available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18 Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied am…
La pluralità dello spazio pubblico: una analisi ricognitiva nel centro storico di Palermo
2011
La letteratura inerente allo sviluppo urbano moderno e postmoderno, da Michel Foucault a Henri Lefebvre, ha aperto un dibattito in merito alla concezione classica di apertura/accessibilità dello spazio pubblico, evidenziando aspetti quali la esclusione spaziale, la sorveglianza e il controllo sociale, la questione del “diritto alla città”. Si assiste ad una progressiva riduzione o sostituzione dello spazio pubblico – privatizzato, fortificato, commercializzato – di cui risentono in primis i soggetti più deboli e marginali. Talvolta emergono nuove forme di produzione sociale dello spazio, ad esempio tramite riappropriazione informale di “luoghi di scarto”. Il lavoro di ricerca ha focalizzato…
Assessing travel time-based accessibility to outdoor ice skating fields for children in Helsinki during the COVID-19 pandemic
2022
This paper was written within the research project called “Equality in suburban physical activity environments, YLLI” (in Finnish: Yhdenvertainen liikunnallinen lähiö, YLLI) funded by the Suburban Programme 2020–2022 (in Finnish: Lähiöohjelma 2020–2022, decision number VN/10837/2020). Informal sport is central to Finnish children’s leisure and physical activity time. This paper aims to build a better understanding of the travel time-based accessibility to informal sports facilities, specifically to ice skating fields, for children and adolescents (aged 7–19) in the city of Helsinki. We focused on the winter of 2020–2021 because COVID-19 restrictions on indoor activities resulted in ice skat…
The Territorial Dimension of Living Lab Approaches: Starting the European “Participant Observatory”
2011
Territory production can be intended as any process of spatial transformation deriving from a sustainable and reciprocal dialogue between local communities and their spatial context along history time; the territory is a dynamic but durable balance between human settlements and their environments. Territory intended in this way - maybe the major competitive factor of regions and their economic actors too - depends less on merely technological advances, rather than socio-technical innovations able to generate better life quality in cities and regions. This is why in the CIP project “Periphèria”, started in November 2010, a European Observatory of LLs and Smart Cities will be set up, conceive…

Turismo musical: conceptualización e implicaciones territoriales. Un análisis exploratorio de los procesos de coordinación turístico-musicales de la …
2023
Some important territories in Central countries have been offering high-value musical activities to their residents for the last two decades, which also attract visitors and therefore generate tourism. In order to address the conceptualization of musical tourism as a general objective, the thesis conducts an in-depth review of the literature and proposes an initial social, economic, and territorial analysis of music and its international evolution, as well as in Spain, where tourism activity constitutes a possible higher evolution for music and requires a local network with coordination relationships between public and private agents. However, there is little empirical evidence and academic…
IEA EBC Annex83 Positive Energy Districts
2021
At a global level, the need for energy efficiency and an increased share of renewable energy sources is evident, as is the crucial role of cities due to the rapid urbanization rate. As a consequence of this, the research work related to Positive Energy Districts (PED) has accelerated in recent years. A common shared definition, as well as technological approaches or methodological issues related to PEDs are still unclear in this development and a global scientific discussion is needed. The International Energy Agency’s Energy in Buildings and Communities Programme (IEA EBC) Annex 83 is the main platform for this international scientific debate and research. This paper describes the challeng…
European Sustainable Urbanisation through port city Regeneration - Case study Catania
2020
Analysis and assessment of a case study in small- and medium-sized port cities. The report describes the trend and proposes a solution to be applied by the Municipality of Catania. This case study has been prepared as a key input to the ESPON project ENSURE – European Sustainable Urbanisation through port city Regeneration. The study consists of three tasks: • task 1, based on statistical analysis and a survey among small and medium-sized port cities in Europe to identify the economic, social and environmental impact of port city regeneration. • task 2, based on a case study comprising four European small and medium-sized port cities of Cork (IE), Aalborg (DK), Brest (FR) and Catania (IT) w…
