This article proposes a methodological reflection on the cultural symbolic dimension of local development processes, according to the development of more effective ways of planning and implementing them, according to sustainable lines of development both from an environmental and socioeconomic point of view, oriented according to a logic of continuous improvement. The reflection develops around three operational phases in which local development paths can be articulated, identifying for each of them specific objectives and strategies to guide the processes of shared representation of the territories and the possible paths of interaction between different local systems: 1) establishment and development of the network of local actors that can be involved in the process, 2) sharing of knowledge on the potential of the local system and definition of possible development paths, 3) sharing of knowledge on local systems with which to interact and definition of interaction strategies.

This work presents the results of a research regarding the élite of Asti and the cultural factors that determine its role in the local governance performance. Starting from determining the difficulties of this territory to elaborate a shared vision of a new and effective trajectory of future development, the research aimed at focusing on the dynamics of power and of shared meanings that hinder this process, with the purpose of identifying possible strategies of change. The composition and stratification of local elite and features of local decision-making process were identified through a mixed method approach, based on positional, reputational, decisional and social network analysis. The analysis of the elite's discourse about local development highlighted a strong polarization both concerning the self-representation of local power and the possible levers of development. On the one hand, an image of power as a closed system, almost exclusively focused on its self-reproduction, in contrast with a more flexible one, based on the management of a territory through local services administration. On the other hand, an expectation of development opportunities almost automatically arising from landscape and natural resources in contrast with an idea of development more based on the opportunities arising form cultural heritage (Palio and local theatre tradition), which could create synergies with University's and local tourism's development strategies.

In light of the challenges that all cities face today, food is offered as a prism through which to read and intervene on various areas that affect the quality of life of the population: circular economy, urban metabolism, social relations, economies, and food quality. In the Roman context, in recent years, numerous initiatives have revitalized the debate on food and brought the discussion to the center of the interest of an ever-increasing number of citizens. However, these experiences appear unrelated and there is a lack of coordination and political coherence. Faced with this evidence, starting from a territorial analysis, this contribution analyzes the process that led a local group of stakeholders to formulate a proposal for a food policy for the city of Rome. The proposal contains a series of possible actions that aim, on the one hand, to recompose the relations between the city and its territory, with a view to re-localization and re-territorialization of agro-food productions and, on the other hand, to reconnect the economic and social relations that the industrialization of food chains has compromised. The network analysis of the bottom-up process, which mainly investigates networking and negotiation skills between various interests, is carried out and related to a careful analysis of the food system in the Roman context. Furthermore, an overview of the state of the art of urban food policies in Italy has been provided to better contextualize the study case. The findings show actors and topics involved in the process, identifying further development towards a more comprehensive participatory process for a systemic food strategy at the metropolitan level.
Engine development has nowadays to deal with a stringent legislation on the pollutant emissions, and a constant attempt to reduce the fuel consumption, as required from the marketing, the governments and the customers. The engine development is high complicated process and CFD simulations play a significant role. They are used at various stages of the design process with different purposes. The goal of this work is to develop a procedure to simulate the mixture formation and wall impingement in GDI engines. In particular, the work is focused on the air motion in-cylinder, on the injection phase, until the mixture formation before the ignition and the research of a correlation between the wall impingement and soot measurement. The ideal workflow is to consider also combustion simulation to relate soot formation estimation with experimental data of emission. The simulation of combustion in gasoline engines is nowadays still in the research phase, and it is generally not used for the engine design. Although it constitutes an interesting research topic, it requires a computation and experimental effort far beyond the current state of the art in the daily engine development process, and it is not covered in this work. On the other end the experimental procedure to measure liquid film formation in engines during the injection process is highly complicated and require facilities not available for this work. All these limitation from simulation and experiments point of view lead us to the decision of correlating wall wet formation of simulation with PN measurement from experiments. The methodology developed is divided in three main simulation: cold flow simulation, injection simulation and wall wet analysis. In the first part the engine flow is validated focusing the attention on velocity magnitude and turbulent kinetic energy fields. In parallel the injection model is calibrated and validate in the spray box, using as target the experimental spray penetration length and droplets size distribution. Once the first 2 simulation are validate, the injection model is implemented in the engine simulation to evaluate the liquid film formation. If a correlation between the in-cylinder wet surface and soot measurement is found, in the future engine development process will be possible to use CFD to estimate liquid film and from that have a prediction of soot formation. This methodology allows to save time and money that always represents a critical point in the engine development.
Il mio lavoro di tesi mira ad analizzare il processo di riforma fondiaria in atto dal 2009 in Burkina Faso, alla luce delle politiche di sviluppo rurale adottate a livello regionale (Africa occidentale francofona) e del percorso storico-politico che dalla conquista coloniale francese ci conduce all'ultima fase di democratizzazione del Burkina Faso. Ripercorrendo le principali strategie ed obiettivi di riforma agraria e fondiaria perseguiti dai Governi a livello regionale e nazionale intendo fare luce sui nodi irrisolti delle politiche di sviluppo rurale e sul rapporto politico che il Burkina Faso ha inteso costruire con il mondo rurale a partire dall'indipendenza, con un particolare focus sul periodo della rivoluzione sankarista (1983-1987). L'analisi storica dei sistemi di riconoscimento dei diritti locali di accesso e utilizzo della terra consente di avanzare riflessioni sull'ordine politico interno che i regimi coloniali e post-coloniali hanno inteso costruire con il mondo rurale e sull'effettiva inclusione della popolazione rurale nelle politiche di sviluppo adottate dai Governi a livello regionale e nazionale. Allo stesso tempo, identificando organi e istituzioni a cui è stato affidato a partire dall'indipendenza il potere di gestire le risorse e conferire diritti fondiari agli abitanti delle aree rurali ho intenzione di far emergere alcuni dei rapporti di forza e di potere esistenti tra livello nazionale e locale e il legame che intercorre tra di essi. L'obiettivo è quello di riflettere sulla possibilità che la riforma fondiaria in atto in Burkina Faso possa garantire una maggiore democraticità dei processi di sviluppo rurale e governance della terra. Attraverso l'analisi di tale processo di riforma è possibile contribuire al dibattito relativo alle strategie di sviluppo rurale in Africa occidentale tenendo conto delle problematicità politiche che tali processi di riforma si trovano ad affrontare ; The ongoing international debate on rural development focuses on the legalization of land property rights as a mean to guarantee land tenure security, to promote agricultural investment and rural development. As a result in francophone West Africa new land policies have been elaborated with the specific aim of resolving a dual institutional and juridical system of land tenure which causes land conflicts and hinder economic growth. My thesis aims to analyze the ongoing process of land tenure reform in Burkina Faso in light of the rural development policies implemented in francophone West Africa since the colonial period. It also takes into account the rural development paths adopted by the Government of Burkina Faso from the French colonial conquest to the late democratization period. By retracing the main strategies of land and agrarian reform at regional and national level I shed light on the unresolved political relationship that the State has built with the rural population since independence. In particular I identify statutory and customary institutions who have been entrusted over time with the power to manage natural resources and to allocate land rights in order to bring out some of the power relationships existing between national and local levels. Through the historical analysis of land tenure systems I advance considerations on the inclusion of rural people in the rural development policies. The main aim is to reflect on the possibility of the ongoing land tenure reform in Burkina Faso to ensure a democratic governance of the land and a more inclusive process of rural development. With this focus on land tenure reform in Burkina Faso my thesis will lead to a critical analysis of the new wave of land policies in West Africa and contribute to the ongoing debate on rural development from a political point of view.
Nowadays the efforts aimed at enhancing the Internal Combustion Engines (ICEs) are mainly focused on the fuel consumption minimization to comply with binding CO2 emission legislation for vehicle homologation. Concerning the Spark-Ignition ICEs, the most widespread path to satisfy the pollutant emission limits is the adoption of a three-way catalyst (TWC) along the exhaust line. As known, this solution poses some issues, such as a low efficiency at cold start or an effectiveness degradation because of aging. In addition, it involves the impossibility to exploit the advantages of lean combustions, since a close to stoichiometric air/fuel mixture is mandatory for efficient TWC operation. For the above reasons, a growing interest towards solutions limiting engine raw emissions is emerging. So future legislation requires new technical measures to increase engine efficiency and reduce pollutant emissions. Here gasoline engines with high specific power have a huge development potential, since, on the one hand, knocking at high Brake Mean Effective Pressure (BMEP) limits thermal efficiency and, on the other hand, high power densities lead to increased thermal loads, which, for component protection reasons, need to be controlled by means of enrichment beyond the stoichiometric air-fuel ratio. This operation leads to increased fuel consumption and to higher pollutant emissions; especially harmful soot particles, hydrocarbons and carbon monoxide are emitted in a higher amount. In addition to known systems, such as exhaust manifolds integrated in the cylinder head for direct cooling of the exhaust gas, extended effective expansion by optimized valve timings (Miller, Atkinson) and external cooled exhaust gas recirculation, also new technologies are being developed for passenger cars. Those technologies primarily aim to widen the lambda one range of the engine in order to maintain the stoichiometric air/fuel ratio throughout the entire engine operating range, which is expected to be required for future Real Driving Emissions (RDE) legislation. The first chapter explains the current situation and future direction of internal combustion engines, with a particular focus on the gasoline engines with high specific power and covers broad regulatory changes in the last year related to tailpipe emissions of criteria pollutants and CO2/fuel economy. Throughout the chapter, a brief overview of internal combustion engines and their future development will be provided so to understand and appreciate why it is still relevant to conduct research in this field, while facilitating the improvement of green technologies in order to achieve a sustainable transportation system. The motivation behind this study and the research direction will also be clarified. Then, a Lamborghini 12-cylinder naturally aspirated spark ignition engine is investigated. The engine is experimentally tested under full and part load operation with two different Air-to-fuel ratio maps. Main performance parameters, in-cylinder pressure cycles and raw pollutant emissions are measured. The engine is schematized in a one-dimensional model (GT-Power™), where "user routines" are employed to simulate turbulence, combustion, knock and pollutant production. 1D model is validated against the experimental data, denoting a good accuracy. The innovative contribution of this section can be hence recognized in the development of a 1D model characterized by a single set of tuning constants allowing for an accurate reproduction of the combustion process in all the engine configurations. As better explained in the following, the combustion model is in fact coupled to a turbulence sub-model, preliminary tuned with reference to 3D-CFD results, in motored operation. This methodology is particularly helpful in the calibration of a VVT engine, where the turbulence levels substantially vary at part load according to the intake/exhaust valve strategies. Combustion and turbulence constants are hence selected through comparisons with few experimental data at full load and 3D results, and then employed at part load and in the optimization process, as well. The results about the raw emissions put into evidence that the numerical approach predicts the experimental data of carbon monoxide (CO) and nitrogen oxides (NO), but it is not enough advanced to reproduce the hydrocarbon (HC) level, although the variations with the engine operating parameters (speed, load, air/fuel ratio) are captured. The model is employed to study the water injection impact to draw the variation trend of the exhaust temperature, performance and the pollutant emissions changing the engine hardware, rather than to predict their absolute levels. The combustion speed takes into account the water presence with a refined correlation of laminar flame velocity and the knock model gives the possibility to set the best spark advance. The water evaporation reduces the in-cylinder temperature and, as a consequence the knock level, is lower. The computed HC, CO and NO maps have been embedded in a vehicle simulation to estimate the impact of the analysed technical solutions on a RDE cycle suggested by Lamborghini. In this way, with a fully numerical approach, a new hardware is analysed and its impact in term of pollutions level is verified on a realistic drive cycle that the new regulations seems to impose. In this way, a new approach to design the future high performance engines has been individuated and the impact of the new regulations can be seen before experimental tests, reducing the time to market and the economic effort. Then, the difference between the engine out emission level and the limit that the regulation imposes can help also to design the after-treatment system. Summarizing, the presented numerical approach showed the potential to predict, on a physical basis, the combined effects of various techniques on the engine performance. This methodology could represent an effective tool to identify the trade-off between engine complexity and expected improvements, contributing to support and drive the development process of new engine/vehicle.
La tecnologia che amplifica la realtà come pure i mezzi tecnologici di acquisizione dei dati, stanno continuando ad avere uno svilup - po difficilmente controllabile o prevedibile. Progetti di un certo interesse, nascono, si sviluppano e muoiono talvolta senza produrre risultati significativi, ma costituendosi come fasi di un processo fluido e dinamico, sul quale vengono costruite nuove applicazioni software e sistemi hardware. Allo stesso tempo, il ruolo dell'accademia sembra venire spesso scavalcato da ciò che viene sviluppato dalla citizen science: ai ricercatori non sembra più spettare esclusivamente il compito della "scoperta", quanto piuttosto la crea - zione di protocolli scientificamente affidabili sulla base di tecnologie spesso utilizzate dalle diverse comunità di citizen scientists in maniera non conforme alle specifiche per le quali erano state progettate. Il contributo propone una riflessione su questi temi prendendo come spunto due sperimentazioni dall'alto contenuto innovativo che abbracciano varie fasi del processo definito con il termine rilievo. Esse riguardano infatti da un lato un sistema hw/sw di acquisizione dati, elaborazione e comunicazione sviluppato per dispositivi mobili ( Progetto Tango ) e una piattaforma mista ROV/UAV multi - sensore dotata di sistema LIDAR e fotocamera digitale per l'acquisizione di dati in luoghi non accessibili ( Progetto Heritagebot ). ; The technology that 'amplifies' the real world as well as the technological means of data capturing, are continuing to have a development difficult to control or predict. Projects of a certain interest are born, develop and die sometimes without producing significant results nevertheless becoming phases of a fluid and dynamic process, on which new software applications and hardware systems are built. At the same time, the role of the academy seems to be often overtaken by what is developed by the citizen science. Researchers no longer seem to exclusively explore the 'discovery' domain, but rather work at the setup of scientifically reliable protocols for technologies often used by different communities of citizens in a way that does not conform to the specifications for which they were originally designed. This paper focuses on these issues taking as its starting point two experiments with high innovative content that cover various stages of the process defined by the term Survey. They pertain on the one hand to a hw/sw system of data capturing, processing and communication developed for mobile devices (Tango Project) and on the other to a mixed ROV/UAV multisensor platform equipped with a LIDAR system and digital camera for data acquisition in inaccessible places (Heritagebot Project).
This bio-bibliographic note presents the main aspects of the economic formation of the author, of the relations with important Italian and foreign economists, of the essential traits of his research on economic policy, the theory of economic growth and development, comparative economic development, labor economics. All this is accompanied by elements of contemporary economic history and by analyses and reflections, in a comparative context, on economic development trends and policies regarding the Italian and European economies, the United States, Germany and the main Asian economies: China, India, Japan, Indonesia and South Korea. The general conclusions are that without sufficiently inclusive and sustainable economic policies any economic development process tends to deteriorate or implode and that economic long-run trends are strongly interwoven to the evolution of historical, institutional, social and political phenomena. ; Questo saggio bio-bibliografico presenta gli aspetti principali della formazione economica dell'autore, dei rapporti avuti con noti economisti italiani e stranieri, della maturazione della sua ricerca su temi relativi alla politica economica, alla teoria della crescita e dello sviluppo economico, agli studi di sviluppo economico comparato ed alla economia e politica del lavoro. Tutto ciò è accompagnato da elementi della storia economica contemporanea della seconda metà del secolo XX e dei due primi decenni di questo secolo e da analisi e riflessioni, in ottica comparativa, sulle politiche e le tendenze di sviluppo dell'economia italiana e di quella europea, nonché alle fasi di crescita o di crisi economica degli Stati Uniti, della Germania e delle maggiori economie dell'Asia. Le conclusioni generali sono che senza una politica sufficientemente inclusiva e sostenibile ogni processo di sviluppo economico tende nel lungo o lunghissimo periodo a deteriorarsi o implodere, e che i mutamenti economici di fondo sono strettamente intrecciati con l'evoluzione della storia, delle istituzioni e dei fenomeni politici e sociali.
Starting from an analysis of the article by Carlo Trigilia " Crescita squilibrata: perché la sociologia economica ha più successo nella teoria che nelle pratiche? (Unbalanced growth: why is economic sociology more successful in theory than in practice?)", Published in 2007 in the journal Stato e Mercato, a theoretical-methodological proposal is developed, from a psychosociological perspective, for the development of an integrated approach of the social sciences to support the policy making processes in the context of socio-economic development policies. This proposal stems from a consideration on the important contribution to the critique of the individualist perspective in the field of psychological and social sciences, elaborated by Massimo Grasso and Sergio Salvatore in their 1997 book "Pensiero e decisionalità. Contributo alla critica della prospettiva individualista in psicologia (Thought and decision making. Contribution to the critique the individualist perspective in psychology", which shows in a clear and detailed manner the crucial importance of the unconscious dimension of social processes and more generally the role of symbolic-affective processes in the social construction of reality that underlies the processes of policy making, as strategies for solving problems of a collective nature.
Otto Hintze was an excellent example of the cultural turmoil that hit historical and political studies in the great crisis between nineteenth and twentieth centuries, with respect to the destiny of the European tradition and its projection in a political world dominated by new universalistic perspectives. Hintze moved thus between a historiography which was for long time attentive to the Prussian case – which he considered almost a paradigm of the modern State – and political science, in constant tension with Weber's contemporary foundation of a comprehensive sociology. The essay attempts to investigate the foundational question of legitimacy as the deepest and most innovative character of Hintze's work. ; Otto Hintze fu esempio eccellente del turbamento culturale che colpì gli studi di storia e politica nella grande crisi sorta fra XIX e XX secolo, rispetto al destino della tradizione europea e la sua proiezione in un mondo politico dominato da nuove prospettive universalistiche. Hintze si mosse così fra una storiografia a lungo attenta al caso prussiano, da lui considerato quasi paradigma dello Stato moderno, ed un punto di vista a carattere politologico, in costante tensione con la contemporanea fondazione, da parte di Max Weber, di una sociologia comprendente. Il saggio cerca di cogliere nel tema fondante della legittimità il carattere più profondo e innovativo dell'opera di Hintze.
The present chapter introduces the concepts and the issues about Italian inner areas, as defined by the Strategia nazionale per le Aree Interne (National Strategy for Inner Areas – SNAI). In particular, it focuses on a new enterprise model called Community-based cooperatives; they play a fundamental role in the regional development process, from economic, social and environmental points of view. Finally, the key elements of these new cooperatives are highlighted.
Il saggio investe le problematiche del territorio rurale e del processo pacificatorio che lo investe chiamando in causa le politiche integrate di sviluppo. Nella trattazione emerge la necessità di inquadrare, in una logica sistemica, i molteplici fattori che fanno da supporto allo sviluppo locale, dalle componenti produttive a quelle turistiche, sociali e culturali, indirizzando le scelte pianificatorie in ragione di un ottimale impiego dei fondi strutturali relativi al nuovo P.O.R. destinati alla politica di sviluppo del settore rurale. ; This paper discusses the problematics of the countryside and the peaceful process that besets it questioning the integrated politics of development. In this discussion there emerges the need to place in a systematic logic the many factors which underpin local development, from the productive ones to the touristic, social, and cultural ones directing the planning choices on the basis of an optimal use of structural funds relative to the new P.O.R. alloted to the politics of development of the rural sector.
