Environment, wealth, inequality and the burden of disease in the Accra metropolitan area, Ghana
2005
The study examines environmental problems and adverse impacts on the health of urban households in the Accra metropolitan area, Ghana. Accra is faced with severe inadequacy of urban infrastructure in the face of rapid population growth in the metropolis. More than half of the city's population do not have access to solid waste collection services. Only 39.8% of households have indoor pipe and over 35.0% of households depend on unsanitary public latrines whilst 2.5% do not have access to toilet facilities. Human excrement, garbage and wastewater are usually deposited in surface drains, open spaces and streams in poor neighbourhoods. The resultant poor sanitation has serious health impacts as…
Mood, Physical, and Mental Load in Spanish Teachers of Urban School: The Role of Intensive or Split Shift
2019
Psychosocial risk factors threaten the health of teachers, who are considered to be a group at high risk of suffering burnout syndrome. The objective of this study is to measure the levels of work satisfaction, burnout, engagement, emotional stability, fatigue, and mood of teachers, depending on their workday: intensive or split shift. A nonexperimental, descriptive–comparative research design is proposed for this study. A follow-up questionnaire has been developed to assess a teacher’s levels of physical fatigue, mental fatigue, and mood at the beginning and end of the 9 days of work analyzed. The study sample consisted of 125 teachers (102 women and 23 men) with a mean age of 38.67 years…
A demand-based methodology for planning the bus network of a small or medium town.
2010
This work aims at developing a demand-based methodology for designing the bus network of a small or medium town. The proposed modelling tool adopts a multi-agent objective function which evaluates performance in the context of different stakeholders: the surplus of travellers (car and bus users); the bus service provider’s revenues and operation costs. This approach was applied to an existing bus network, serving city of Trapani, which is a medium town in the south of Italy (Sicily), with 100000 inhabitants. The bus-based public transport system attracts only about 5% of commuter trips within Trapani (source: National Institute of Statistics, 2005). This paper reports on an analysis of the …
Contrasting Effects of Chronic Anthropogenic Disturbance on Activity and Species Richness of Insectivorous Bats in Neotropical Dry Forest
2022
For prioritizing conservation actions, it is vital to understand how ecologically diverse species respond to environmental change caused by human activity. This is particularly necessary considering that chronic human disturbance is a threat to biodiversity worldwide. Depending on how species tolerate and adapt to such disturbance, ecological integrity and ecosystem services will be more or less affected. Bats are a species-rich and functionally diverse group, with important roles in ecosystems, and are therefore recognized as a good model group for assessing the impact of environmental change. Their populations have decreased in several regions, especially in the tropics, and are threatene…
Cylindromatosis (Cyld) gene mutation in T cells promotes the development of an IL-9-dependent allergic phenotype in experimental asthma
2016
Cylindromatosis (CYLD) is a ubiquitously expressed deubiquitinating enzyme which removes activating ubiquitin residues from important signaling molecules of the NF-κB pathway. In CYLDex7/8 transgenic mice, a naturally occurring short isoform (sCYLD) is overexpressed in the absence of full length CYLD, leading to excessive NF-κB activity. Herein, we investigated the impact of the CYLDex7/8 mutation selectively in T cells on the development of experimental allergic airway disease induced by sensitization and challenge with ovalbumin. Compared with their wildtype littermates, mice bearing the T cell-specific mutation (CD4+CYLDex7/8) display stronger eosinophilia and mucus production in the lun…

Le lenti del Sud: informalità mediterranea e rivoluzioni post- pandemiche nel quartiere CEP di Palermo
2021
I fenomeni di abitazione informale si declinano in modalità eterogenee e complesse. La specificità dei contesti sud-europei induce a mettere in crisi i modelli che interpretano questi temi seguendo le esperienze anglosassoni o nord-europei e a sviluppare un filone di ragionamento teorico che tenti di scardinare il legame tra informalità e ritardo (economico, sociale, culturale). Questo contributo tenta dunque di fornire una chiave di lettura innovativa, a partire dal caso studio del quartiere CEP di Palermo, dove l’informalità non si declina esclusivamente nelle pratiche abitative ma si spinge oltre la dimensione privata, nello spazio pubblico. Se è vero che l’esperienza pandemica contempor…

Città aumentate : dieci gesti-barriera per il futuro
2021
Attraverso dieci «gesti-barriera», pensati per rendere città grandi e piccole a prova di crisi (di cui quella da Covid-19 è solo l’ennesima manifestazione) e per cambiare un modo di vivere urbano percepito come inaccettabile, Città Aumentate si propone come una guida concettuale e operativa per i cittadini, i progettisti, gli imprenditori e gli amministratori desiderosi di mettere in atto qui e ora un’innovazione urbana sempre più necessaria. Maurizio Carta suggerisce dieci modalità d’azione simili a quelle che nei videogiochi l’eroe o l’eroina usano per cavarsela da situazioni difficili, che i cittadini e le istituzioni sono invitati ad adottare per salvarsi dalle gravi patologie del corre…
Città della prossimità aumentata
2021
La sfida per le città aumentate antisindemiche sarà quella di recuperare il loro naturale policentrismo, la diversità dei loro quartieri e borgate che, smettendo di essere fragili periferie senza diritti, tornino ad essere luoghi di vite e non solo di abitazioni, colmando il divario educativo, lavorativo, sanitario, culturale, digitale, dotandosi di micro-presìdi di salute pubblica e di comunità energetiche autosufficienti. Immagino città fondate su una nuova prossemica che riduca la loro forsennata mobilità centripeta, garantendo la risposta a molti bisogni entro un raggio di 15 minuti a piedi (lo stanno già facendo Parigi, Barcellona, Milano, Bologna). Voglio proporre qui una “città della…
