Alla base del processo: scientificità del progetto e attualità dei fondamenti teorici
2020
Di fronte a kaos e kosmos, ordine e disordine, teorizzazione generale e pensiero “debole”, modernità, postmodernità, surmodernità… l'uomo oggi non è in grado di formarsi un'opinione assoluta su nulla. Fare una scelta può creare problemi, forse anche disperazione, essere costretti a optare per più scelte conseguenti, come accade nel processo progettuale, può diventare davvero un dramma insolubile. Considerati questi aspetti, riteniamo sia necessario soffermarsi per fare alcune considerazioni (anche se relative e parziali) sulla disciplina, sui suoi fondamenti scientifici e sulla loro effettiva concretizzazione nel progetto architettonico. Possibili considerazioni sui fondamenti dell'architet…
Retrieval of characteristic parameters for water vapour transmittance in the development of ground based Sun-Sky radiometric measurements of columnar…
2014
Abstract. Sun–sky radiometers are instruments created for aerosol study, but they can measure in the water vapour absorption band allowing the estimation of columnar water vapour in clear sky simultaneously with aerosol characteristics, with high temporal resolution. A new methodology is presented for estimating calibration parameters (i.e. characteristic parameters of the atmospheric transmittance and solar calibration constant) directly from the sun–sky radiometer measurements. The methodology is based on the hypothesis that characteristic parameters of the atmospheric transmittance are dependent on vertical profiles of pressure, temperature and moisture occurring at each site of measurem…
Precipitable water vapour content from ESR/SKYNET sun-sky radiometers: validation against GNSS/GPS and AERONET over three different sites in Europe
2018
The estimation of the precipitable water vapour content (W) with high temporal and spatial resolution is of great interest to both meteorological and climatological studies. Several methodologies based on remote sensing techniques have been recently developed in order to obtain accurate and frequent measurements of this atmospheric parameter. Among them, the relative low cost and easy deployment of sun–sky radiometers, or sun photometers, operating in several international networks, allowed the development of automatic estimations of W from these instruments with high temporal resolution. However, the great problem of this methodology is the estimation of the sun-photometric calibration par…
Application of mobile aerosol and trace gas measurements for the investigation of megacity air pollution emissions: the Paris metropolitan area
2013
For the investigation of megacity emission development and the impact outside the source region, mobile aerosol and trace gas measurements were carried out in the Paris metropolitan area between 1 July and 31 July 2009 (summer conditions) and 15 January and 15 February 2010 (winter conditions) in the framework of the European Union FP7 MEGAPOLI project. Two mobile laboratories, MoLa and MOSQUITA, were deployed, and here an overview of these measurements and an investigation of the applicability of such measurements for the analysis of megacity emissions are presented. Both laboratories measured physical and chemical properties of fine and ultrafine aerosol particles as well as gas phase con…

Reproduction behaviors : permanencies and changes : for a contextual and dynamic approach of the fertility
2015
Current levels of African fertility are, for most observers, the expression of a continuation of traditional values of ancestral essence. For those observers, the traditional values continue to determine reproductive behavior, despite the economic, political and social changes. Based on the case of the Republic of Congo, dynamic and contextual analysis of these behaviors, reveal that these are rather clear break from the current level of fertility; they suggest significant unmet need for birth control. It is possible that a Malthusian reflex develops gradually, which does not exclude the need for children, contrary to some theories. These behaviors are characterized by profound changes resu…
Shared Value and Philanthropy: the Potential Role of Corporate Foundations
2016
This paper deals with the topic of research of Corporate Foundations (CFs), aiming at stressing how these organization have been studied so far, and how it could be possible to reconsider their role in the domain of philanthropic initiatives. In particular, this study aims to reconsider the phenomenon of Corporate Foundations under the shared value perspective, highlighting the ability of these organizations to respond to requests of multiple categories of stakeholders. Through the analysis of CFs peculiarities the study will underline the characteristics that are suitable for taking into consideration the potential role of CFs, by means of creating value for both society and firm. Thus, th…
A Quick Approach to the Microfoundations of Social Entrepreneurship
2021
The very first section of the book deals with the phenomenon of social entrepreneurship from a microeconomics perspective. In this line, the individual represents the unit of analysis, that is, the social entrepreneur. Social entrepreneurs are agents who intend to make a positive change in society in such a way that their solution presents a tool to improve the quality of life of the segment of the population they want to target. In these first pages, our intention has been to explain what is inside the mind of the social entrepreneur in the process of developing the idea and putting it into practice. We assumed that entrepreneurs are individuals forming part of a particular society and con…
A multi-purpose, multi-rotor drone system for long-range and high-altitude volcanic gas plume measurements
2021
A multi-rotor drone has been adapted for studies of volcanic gas plumes. This adaptation includes improved capacity for high-altitude and long-range, real-time SO2 concentration monitoring, long-range manual control, remotely activated bag sampling and plume speed measurement capability. The drone is capable of acting as a stable platform for various instrument configurations, including multi-component gas analysis system (MultiGAS) instruments for in situ measurements of SO2, H2S, and CO2 concentrations in the gas plume and portable differential optical absorption spectrometer (MobileDOAS) instruments for spectroscopic measurement of total SO2 emission rate, remotely controlled gas samplin…
Ética del discurso: ¿un marco filosófico para la neuroética?
2013
Neuroethics requires a framework of philosophical ethics from which to interprete, integrate and criticiseneuroscientific progress in moral field. This article sets out to: 1) Show to what extent this framework is necessary; 2) Tackle the question of the method for constructing this framework; 3) Compile the main tópoi of the neurosciences that the framework has to interpret and integrate; 4) Propose the ethics of discourse as a philosophical framework for neuroethics; 5) Display certain shortcomings of this framework and put forward the dialogical ethics of cordial reason as being more appropriate.La Neuroética necesita un marco de ética filosófica desde el que interpretar, integrar y crit…
