Città e organismi territoriali. Verso un approccio olistico alle crisi dell’Antropocene
2021
From the second half of the nineteenth century, urban planning was understood, according to a top-down approach managed by government systems, as a cure for the city affected by the disease, injustice, and violence. This approach, aimed at regulating the behaviour of producers in cities and territories, aims at favouring the strongest economic and social actors to the detriment of the weakest social tissues. Today, the various factors of economic and social crisis, which act on a global scale, have made the picture of inequalities even more complicated and uncertain than in the past. Consequently, the technocratic responses provided by central governments are no longer enough and indeed som…
Dall’iper–densificazione all’abbandono: la negazione della qualità della vita nella città moderna
2021
A partire dall’Ottocento si assiste ad un fenomeno che porta le città europee ad ingrandirsi ed espandersi. Non si tratta solo di un’estensione territoriale, ma anche di un incremento della densificazione dovuto agli ingenti spostamenti di popolazione dalle campagne ai centri urbani. Il fenomeno della densificazione non deve essere inteso solo come rapporto tra la superficie e il numero degli abitanti, ma anche come complessità delle relazioni sociali ed è un processo che dalle città si estende alla dimensione planetaria a causa delle tecnologie che hanno trasformato il mondo in un villaggio globale. Dopo aver messo a fuoco le componenti storiche, economiche politiche e sociali che determin…
Green cities, eco-quartieri e dimensione intermedia. Per una nuova stagione di rigenerazione urbana
2014
Il contributo affronta la relazione tra l’emergente sensibilità ecologica del progetto urbanistico e le diffuse esperienze europee di eco-quartieri, a partire dalla considerazione che proprio nella scala intermedia tra l’oggetto architettonico e quella del sistema insediativo nel suo complesso possa trovarsi la dimensione più adatta in cui sperimentare l’inversione del modello di sviluppo e visioni per città più sostenibili. Il quartiere, infatti, nel richiamare prospettive multiscalari del ragionamento sul sistema urbano e ponendosi come interfaccia tra tessuto urbano e vita familiare rimanda ad una dimensione dell’abitare in cui alimentare un rinnovato senso di comunità fondato su nuovi s…
Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…
An Economic Assessment of Micro-Scale Use of Renewable Energy Sources: Two Case Studies
2015
During recent times, renewable energy technologies have shown a relative fast growth in the global energy investment, global energy capacity and their integration within multiple sectors, particularly in the electricity sector. Renewable energy technologies have also experienced notorious declining costs on their manufacturing production. Nevertheless, while this growth is widely acknowledged, the share of renewables with respect total energy production has been moderate. Technological advancements in renewable energy have demonstrated the potential of renewables in energy generation and also that renewables can provide direct and indirect advantages over their counterparts. This thesis inv…
Applicability of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) bark extract as a precursor of rigid carbon foam and activated carbon
2023
Hybrid aspens have long attracted scientific interest, but the research on their use as feedstocks for chemical applications are still very limited. The bark biomass of the poplar species contains many valuable extractives that can be utilized as value-added products. This paper examines the applicability of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) bark extract as a precursor of rigid carbon foam and activated carbon. To explore this, the study considers 1) the basic chemical composition of the bark in terms of added value potential, 2) the basic chemical composition of the bark extract and the effect of its pretreatment on the extract composition, 3) the production of rigi…
Roczna wydajność instalacji PV zamontowanej na dachu budynku dydaktycznego Uniwersytetu Opolskiego
2018
Celem badań była analiza i ocena sprawności pracy instalacji fotowoltaicznej zamontowanej na dachu budynku dydaktycznego Uniwersytetu Opolskiego mieszczącego się przy ul. Kominka 6 w Opolu. Zakres pracy obejmował ocenę: energetyczną - uzysku energetycznego (ilość wyprodukowanego prądu a położenie geograficzne paneli fotowoltaicznych) i ekologiczną - redukcja emisji szkodliwych substancji niewyemitowanych do aerozolu atmosferycznego z powodu produkcji prądu przez instalację PV, a niedostarczonej przez elektrownię opalaną węglem. Badania wykazały dobry wynik uzysku energetycznego w ciągu roku - 5,30 MWh energii z tego systemu oraz znaczną redukcję emisji CO2 do atmosfery - 4,27 Mg/rok, co pot…
INNOVATION AND NEW TECHNOLOGIES TO ENHANCE THE ARCHITECTURAL HERITAGE IN THE HISTORIC CITY.THEORY AND TOOLS
2016
The ancient heritage is a fundamental territorial resource, the reason why territory protection and conservation have to be reinforced, as much as it’s necessary to improve its promotion and responsible use. In particular, cultural heritage promotion inside the cultural circuit, gives the chance to own the territory in terms of social and tourist resource. In this perspective, the process of valorization of the historical sites must be proactive and strategic in order to spread knowledge of cultural heritage, through the use of advanced tools for the understanding of the exhibition in the museum context; but also to improve the public use. As part of integrated strategies for sustainable de…
An intergenerational competency framework : Competencies for knowledge sustainability and start‐up development in the digital age
2022
In this study, we looked at the competencies and changes in the competency spectrum required for global start-ups in the digital age. Specifically, we explored intergenerational collaboration as an intervention in which experienced business-people from senior adult groups support young entrepreneurs. We conducted a Delphi study with 20 experts from different disciplines, considering the study context. The results of this study shed light on understanding the necessary competencies of entrepreneurs for intergenerationally supported start-up innovation by providing 27 competencies categorized as follows: intergenerational safety facilitation, cultural awareness, virtues for growth, effectual …
Aktywność sołectw wspierających rozwój społeczny w ramach Programu Odnowy Wsi w latach 2013-2015
2018
Odnowa wsi jako metoda rozwoju stanowi jeden ze sposobów osiągania celów rozwojowych, rozumianych nie tylko w kontekście poprawy jakości infrastruktury, ale poprawy szeroko rozumianej jakości życia, której nie osiągniemy bez zaangażowania samych mieszkańców. Celem artykułu jest przedstawienie Programu Odnowy Wsi (na przykładzie województwa opolskiego) jako elementu przyczyniającego się do rozwoju kapitału społecznego, czego wyrazem może być liczba przedsięwzięć realizowanych przez poszczególne sołectwa. Zostały przeanalizowane sprawozdania sołectw (około 600 rocznie) z realizacji programu w latach 2013-2015. Podstawową metodą prezentacji wyników badań jest analiza opisowa z użyciem metod il…
