Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo
2022
Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…
Optimization of Data Harvesters Deployment in an Urban Areas for an Emergency Scenario
2013
International audience; Since its appearance in the VANETs research community, data collection where vehicles have to explore an area and collect various local data, brings various issues and challenges. Some architectures were proposed to meet data collection requirements. They can be classified into two categories: Decentralized and Centralized self-organizing where different components and techniques are used depending on the application type. In this paper, we treat time-constrained applications in the context of search and rescue missions. For this reason, we propose a centralized architecture where a central unit plans and manages a set of vehicles namely harvesters to get a clear ove…
On the volume of unit vector fields on spaces of constant sectional curvature
2004
A unit vector field X on a Riemannian manifold determines a submanifold in the unit tangent bundle. The volume of X is the volume of this submanifold for the induced Sasaki metric. It is known that the parallel fields are the trivial minima.
El Derecho a la Ciudad desde la perspectiva de género en el Barrio El Gallito (Guatemala)
2019
Las ciudades del mundo concentran poderes económicos y sociales y, sus por su propia idiosincrasia ofrecen las herramientas necesarias para hacer frente a los nuevos desafíos del desarrollo. No obstante, según ha manifestado recientemente Naciones Unidas (2018) el aumento de la vulnerabilidad y de la exclusión social, ha conllevado directamente a un crecimiento notable de las desigualdades entre regiones y ciudades. Además de ello, en las últimas décadas han emergido con fuerza espacios urbanos en los que los desequilibrios sociales, la escasez de recursos comunitarios, el deterioro y degradación del entorno, se han visto acentuados dentro de las ciudades dando lugar a los denominados barri…
SEA presidential address: Group connectivity and cooperation
2011
A model-free methodology is used for the first time to estimate a daily volatility index (VIBEX-NEW) for the Spanish financial market.We use a public data set of daily option prices to compute this index and showthat daily changes in VIBEXNEW display a negative, tight contemporaneous relationship with IBEX daily returns, contrary to other common volatility indicators, as an implied volatility indicator or a GARCH(1,1) conditional volatility model. This relationship is approximately symmetric to the sign on VIBEX-NEW changes and asymmetric to the IBEX-35 returns sign, which make it clearly a suitable volatility index for the Spanish stock market. We also examine the relationship between curr…
Pointwise k-Pseudo Metric Space
2021
In this paper, the concept of a k-(quasi) pseudo metric is generalized to the L-fuzzy case, called a pointwise k-(quasi) pseudo metric, which is considered to be a map d:J(LX)×J(LX)⟶[0,∞) satisfying some conditions. What is more, it is proved that the category of pointwise k-pseudo metric spaces is isomorphic to the category of symmetric pointwise k-remote neighborhood ball spaces. Besides, some L-topological structures induced by a pointwise k-quasi-pseudo metric are obtained, including an L-quasi neighborhood system, an L-topology, an L-closure operator, an L-interior operator, and a pointwise quasi-uniformity.
Ewolucja roli mniejszości niemieckiej w Polsce oraz Polonii w Niemczech w stosunkach polsko-niemieckich pod koniec XX wieku i na początku XXI wieku
2016
Both German minority in Poland and Polonia in Germany constitute undoubtedly – along with the history, geographical location and common membership of the Republic of Poland’s and German Federal Republic’s to EU and NATO – one of more important determinants of relations between both states. As to the issue of execution of rights of Germans in Poland and Polonia in German the breakthrough took place as a result of signing Treaty on good neighborhood and friendly cooperation on 17.06.1991. On both sides though there are the charges formulated about the lack of full execution of the Treaty provisions. The subject of controversy is, on the one hand, their status – inequality of terminology used …
Towards the Environmental Sustainability of the Construction Sector: Life Cycle Environmental Impacts of Buildings Retrofit
2022
In the context of the need for carbon emissions reduction, the buildingsector, as one of the most energy intensive one, needs tools and approaches towards carbon neutrality and the increase of the buildings overall energy performances. The paper proposes an integrated approach towards the environmental performances analysis of a small neighborhood having as goal the achievement of the Positive Energy District target and the assessment of its environmental impacts. The methodology proposed includes building modeling and dynamic energy simulation using the Energy Plus engine and a simplified Life Cycle Assessment approach. Two scenarios are investigated: i) the existing neighborhood, ii) the …
Vivibilità e creatività delle periferie
2020
Consumare meno suolo significa riscoprire la vita in città, riqualificando ambiti degradati, consolidando le piccole centralità mediante spazi pubblici e funzioni aggreganti, sostenendo e incentivando la “ricucitura” di architetture dismesse e parti di città poco vivibili. La “memoria” identitaria e la dimensione ecologico-paesaggistica in chiave creativa delle città possono, e devono, divenire un volano per innescare vivibilità soprattutto nei contesti urbani difficili. Partendo dal concetto di milieu, un approccio creativo bottom up può costituire la base operativa per una vision che, ancor prima di avere una dimensione urbana, ne abbia una “umana”. Nell’obiettivo ultimo di affrontare tem…
Community Development and Social Participation
2011
The paper presents the reslt of the action research project issued in Palermo (Southern Italy), in disadvantaged urban suburbs, methodologically based on Kurt Lewin's field theory - that is a three-step spiral process of planning which involves recoinnaissance; talking actions; and fact-finding about the results of the action - in order to develop the social participation and the social change. The principal aim of the project was the empowerment of participants, obtaining their collaboration through participation, giving them acquisition of knowledge for a real social change.
