Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
Déplacements et mutations spatiales à Alger
2019
Algiers port and city’s exceptional history is driven by its remarkable site nestled on a rocky spur. Revealed.Yet this morphology constrained the urban growth of a city that could pretend joigning the ranks of large metropolis. During its history port and city relationship took multiple forms, frequently compatible yet sometimes divergent and even opposed, leading to inversing domination status of both actors. Algiers capital of a 40 million inhabitants state, has always been a laboratory of urban politics since the colonial era to the institutional constructions of independent Algeria, regardless of deficient statistical tools. However, the space in Algiers is confronted to great challeng…
Evaluating Socio-economic Impact of Age-Friendly Environments
2018
According to the World Health Organization (WHO) (2007), physical and social environments are key determinants of whether people can remain healthy, independent and autonomous. Health and well-being are not only determined by our personal characteristics but also by the envi-ronment where we were born and where we live throughout our life (WHO 2015). In fact, promoting age-friendly environments (AFE) is the most effective approach for responding to demographic change because they empower elderly people to age in better health, they pro-mote their social inclusion and active participation, and they help them to live autonomously into old age (Parent 2012). AFE foster health, well-being and t…
The Role of Technology in Participative Processes
2016
Smart city is more and more, in the common feeling, the crossroad of technologies, but first and foremost, the place where humans, contexts and technologies meet and must interact. Technological systems thanks to the deep human interaction acquire an uncertain behaviour that can be hardly modelled and controlled. The resulting complexity, cannot be easily handled with the tools that are available to separate scientific fields. The interdisciplinarity that comes from the implementation of technologies and the dialogue between these and the territories requires new tools for classification and design. New urban design tools are needed allowing to identify in a standardized way adequate suppor…
Strategie ecosistemiche e infrastrutture verdi in simbiosi con il costruito
2022
Il numero 11 di AGATHÓN raccoglie saggi, studi, ricerche e progetti sul tema Vegetazione | La sua Simbiosi con il Costruito richiamando il ruolo che la Natura in generale e la Vegetazione in particolare possono svolgere nel breve periodo per affrontare l’attuale sfida del surriscaldamento globale e dei cambiamenti climatici causati da deforestazioni e incendi boschivi, urbanizzazioni selvagge, uso indiscriminato di materie prime non rinnovabili e incremento delle emissioni di anidride carbonica, tutti fattori che determinano un impatto devastante sul nostro ormai fragile ecosistema, sulla società e sull’economia. Se Simon aveva intuito già nel 1969 il potenziale di una ‘nuova ecologia’ in c…
Green infrastructures for the energetic and environmental sustainability of cities
2019
The inexorable extension of urbanization is consuming huge amounts of soil drastically reducing natural vegetation, replacing it with buildings and low albedo surfaces. The changes due to the different thermal properties of surface materials and the lack of evapotranspiration in urban areas lead to a phenomenon known as "urban heat island effect". By reintroducing the vegetation back into the urban landscape, a partnership between nature and cities should be strengthened to create a new sustainable urban environment. Since the outer surfaces of building offer a great amount of space for vegetation, planting on roofs and walls has become one of the most innovative way to provide several envi…
L'évaluation socio-économique des infrastructures de transport : enrichir les approches du développement territorial
2007
International audience; Dans les années récentes, en France, le processus décisionnel en matière de grands équipements a sensiblement évolué, débouchant sur des réponses institutionnelles en termes de procédures adaptées. Ceci a eu pour conséquence d'accroître l'exigence informationnelle destinée à alimenter les débats, éclairer les problématiques abordées, leur donner un contenu le plus objectivé possible. L'une des principales thématiques systématiquement abordées dans le cadre de ces procédures participatives, est celle du développement territorial, dont l'importance en fait un des éléments essentiels de l'acceptabilité sociale. Les enseignements des observatoires socio-économiques autor…
The endogeneous nature of the dynamic analysis among classical economist's writings
1998
« Endogenous growth theories » exhibit different models in which growth is assumed to come from the accumulation of a particular factor (human capital, technology, public infrastructures, etc.). However, due to its newness, the real term of « endogenous growth » seems to playdown old theories.This paper intends to put right this position and demonstrate that relations displayed by current models are only formalizations stemming from the developments of classical economists. In the end, we demonstrate that their analysis yields new viewpoints for analysts. Overall, we wish to reinforce theendogenous nature of the dynamic analysis among classical economist's writings.
