Full textAbstract:
I sistemi agroalimentari al contempo trasformano i territori di riferimento e si adattano ad essi e alle loro configurazioni urbane. Leggere queste interdipendenze risulta cruciale in termini di spazio e occupazione del suolo, soprattutto alla luce della scala globale di molte filiere del cibo. Il Veneto si offre come caso paradigmatico dei territori a diffusione urbana europei, in cui gli spazi della produzione, della distribuzione e del consumo di cibo sono in prossimità fisica tra loro.

Full textAbstract:
La città fluida costituisce una delle recenti concettualizzazioni utilizzate per identificare i processi che attraversano la città contemporanea. La trasposizione del concetto di fluidità nella pianificazione e nella morfologia urbana consente di osservare come il dinamismo, la temporaneità, la flessibilità siano adottate come categorie per la rifunzionalizzazione, la risignificazione degli spazi, la creazione dei luoghi e la diffusione di nuove pratiche. Il contributo propone una riflessione sull'esigenza di individuare un approccio alla pianificazione urbana capace di gestire la fluidità e la complessità urbana contemporanea.

Full textAbstract:
L'articolo analizza la dinamica localizzativa di medio-periodo (2001-2018) della popolazione residente straniera a Bologna e Milano. L'obiettivo è comprendere gli elementi in comune, le specificità e le trasformazioni dei modelli residenziali dei cittadini stranieri nei due contesti urbani Sud-europei. L'analisi statistica e spaziale dei più recenti dati amministrativi conferma l'assenza di fenomeni di segregazione urbana ed evidenzia la tendenza alla diffusione territoriale della presenza straniera e la crescente configurazione periferica delle aree con concentrazione. Le specifici-tà dei due casi suggeriscono inoltre la rilevanza dei fattori locali per comprendere i processi di insediamento degli stranieri. Dopo una sintetica rassegna della letteratura, sono presentati i risultati dell'analisi diacronica e, infine, viene messo in eviden-za il contributo che lo studio fornisce al dibattito sui modelli insediativi delle popolazioni straniere nei contesti urbani Sud-europei.

Il saggio affronta il tema della circolarita economica e urbana intesa come sottoinsieme del paradigma della sostenibilita, evidenziando potenzialita e limiti di un nuovo modello in via di affermazione e diffusione a scala planetaria. Il ragionamento critico prende le mosse dalla recente produzione di documenti istituzionali e l'ancora ridotta produzione scientifica sull'argomento per proporre un'interpretazione non ortodossa sul rapporto fra circolarita e citta.

Full textAbstract:
- Cities were the natural environment for the spread of telephone services in the early phase of the new technology of vocal communication. The expansion of the telephone in the Spanish cities took place with a relative delay with respect to other European countries. The reasons for this relative delay were as much economic (rent and tariffs) as institutional, mainly the unstable government policy and the regime of concessions. The period between 1877-1930 analyzed here is rich in contrasts since it includes the passage from an overwhelming predominance of local networks, private as well as public, to a regime of virtual monopoly towards the creation of a system unified under a private monopoly with very few exceptions.

L'articolo propone quattro scenari per restituire diverse intensità/modalità/velocità di diffusione dei veicoli elettrici nella Regione urbana milanese. Gli scenari, costruiti con un'analisi multicriteri che analizza le relazioni tra mobilità elettrica, pratiche di mobilità, caratteristiche socio-economiche e insediative, offrono elementi per definire politiche di incentivo e di regolazione per una transizione sostenibile ed equa verso una mobilità a basse emissioni di carbonio.

Le dinamiche territoriali, economiche e sociali delle popolazioni migranti impattano le - e contribuiscono alle - trasformazioni della città. Il contributo presenta una prima indagine, condotta in una porzione di centro città di Napoli, sul fenomeno della grande diffusione delle attività per la vendita di beni di uso quotidiano con titolarità extra-ue. Lo studio è finalizzato a indagare, in termini di opportunità o limitazioni, da un lato le implicazioni che tali attività hanno sulle dinamiche territoriali, dall'altro il ruolo che l'apertura di questi piccoli negozi può avere nei percorsi migratori.

In occasione del centenario dalla fondazione di Welwyn Garden City (1920-2020), questo servizio è dedicato alla citta` giardino, da considerare forse la più radicale e rilevante eredita` del ‘town planning and design' britannico e della tradizione utopistica. I saggi che costituiscono la sezione partono tutti da una riconsiderazione dei principi iniziali di Ebenezer Howard, mettendone in luce aspetti differenti, per analizzare la diffusione coeva del modello in ambito europeo e statunitense, o aspetti non scontati come la relazione tra pianificazione urbana e questione alimentare. L'obiettivo e` una valutazione sul lascito delle citta` giardino, come una vicenda, fra teoria e prassi, della pianificazione e del disegno della citta` all'origine di molte questioni della citta` contemporanea.

Full textAbstract:
La diffusione dell'infezione da Sars-CoV2 e la crisi di sistema, che ne è conseguita, hanno generato una serie di impatti che vanno ben oltre il campo dell'epidemiologia investendo anche l'ambito della formazione accademica dei futuri pianificatori sotto il profilo sia dei contenuti che delle metodologie didattiche. L'articolo restituisce una riflessione critica sull'impatto della pandemia da Covid-19 sull'insegnamento del planning a partire dalle esperienze didattiche condotte dall'autore presso il Corso di laurea magistrale in Pianificazione territoriale urbanistica e ambientale dell'Università degli Studi di Palermo. Un'occasione per avviare un ragionamento più ampio non solo sulle competenze richieste ai pianificatori all'indomani della crisi pandemica ma più in generale su come i corsi di laurea in Pianificazione urbana e territoriale si stanno attrezzando nel fornire agli studenti le competenze necessarie per affrontare le sfide poste dal post-pandemia.

Full textAbstract:
La diffusione degli spazi collaborativi è un fenomeno che si è accentuato notevolmente nell'ultimo decennio sia come risposta alle trasformazioni in atto nel mondo del lavoro (au-mento dei freelance e knowledge workers, digitalizzazione e remote working), sia come con-seguenza della forte spinta alla creatività e all'innovazione a livello individuale, aziendale e territoriale. Inoltre, gli spazi collaborativi sono il risultato di processi di rigenerazione urbana di edifici abbandonati e in disuso, che rappresentano l'eredità di un'economia industriale sop-piantata dall'economia della conoscenza e delle relazioni. Lo studio propone una panoramica degli spazi collaborativi in Emilia-Romagna, identificandone le caratteristiche principali e il ruolo che svolgono per le persone che li frequentano. Infine, lo studio si propone di illustrare gli impatti della pandemia sugli spazi collaborativi e le modalità con cui i gestori degli spazi stanno rispondendo alle sfide emergenti.

Full textAbstract:
The Noi Techpark project in Bolzano has substantially transformed a portion of the Bolzano surroundings, localizing university and management functions in an area characterized by the presence of a dismissed industrial settlement built between the two World Wars by the Montecatini group. The project was pursued through the creation of a technology park, renovating the structures of the old factory which was in a state of abandon and then acquired by the Autonomous Province of Bolzano. This allowed the establishment of a pole of new public- private structures for technology transfer. The present paper intends to retrace the history of this intervention, describing its main characteristics in terms of urban form, functions and presence of public spaces in relation to the achievement of the objective of re- evaluating an entire urban area. including the relevant residential zone. But at the same time the ambition of the essay lies in the attempt to represent how, in the assessment of the complexity of local policies of territorial development, a significant role is played by the ability to contribute to economic growth in terms of birth of new businesses, improvement of competitiveness of existing ones, enhancement of financial resources, human and material present in the area and, finally, the ability to attract new productive factors in the area. In this sense, the Noi Techpark project is emblematic. Il Progetto Noi Techpark a Bolzano ha trasformato in maniera sostanziale una porzione consistente della periferia di Bolzano, localizzando funzioni universitarie e direzionali in un’area caratterizzata dalla presenza di un insediamento industriale dismesso realizzato, negli anni tra le due guerre mondiali, dal gruppo Montecatini. L’intervento è stato perseguito mediante la realizzazione di un parco tecnologico che, attraverso il risanamento delle strutture del vecchio opificio – acquisito al patrimonio della Provincia autonoma di Bolzano dopo il suo abbandono – ha permesso l’istituzione di un polo di nuove strutture pubblico-private destinate al trasferimento tecnologico. Il presente contributo intende ripercorrere la storia di questo intervento, soffermandosi nel descriverne le principali caratteristiche in termini di forma urbana, funzioni e presenza di spazi pubblici in relazione al raggiungimento dell’obiettivo di rivalutare un’intera area urbana. Ivi compreso quella occupata dal tessuto residenziale di pertinenza. Ma allo stesso tempo l’ambizione del saggio risiede nel tentativo di rappresentare come, nella valutazione della complessità delle politi- che di sviluppo locale di un territorio, un ruolo rilevante sia ricoperto dalla capacità di contribuire alla crescita economica nei termini di nascita di nuove imprese, di miglioramento della competitività di quelle esistenti, di valorizzazione delle risorse finanziarie, umane e materiali presenti in loco e, infine, dalla capacità di attrarre nuovi fattori produttivi sul territorio. Proprio in questo senso Il progetto del parco tecnologico Noi Techpark sembra emblematico. Nell’aver perseguito, oltre al risanamento di un’area industriale di smessa, l’obiettivo della creazione e della diffusione dell’innovazione per mezzo di un brand territoriale. In questo modo, al vantaggio di arginare la perdita di valore del contesto edilizio dell’intera area, si aggiunge il risultato prestigioso di aver messo in contatto i laboratori di ricerca, da un lato, e il tessuto imprenditoriale, dell’altro. L’intera operazione restituisce, dunque, un contesto entro cui è stato possibile sviluppare la capacità di trasferire know-how, di diffondere informazioni tecnologiche sul territorio, di creare un network di relazioni che stanno alla base della diffusione e della creazione della conoscenza e dello sviluppo di un ambito territoriale. Tutti elementi, non immediatamente quantificabili in termini economici nel breve periodo, ma che ci sembra debbano essere presi in considerazione nelle valutazioni complessive del vantaggio dell’opportunità di portare a termine questo tipo di iniziative.

El texto analiza un triple caso de estudio en el que se aplicaron técnicas cualitativas en áreas periféricas populares al oriente de la zona metropolitana de la Ciudad de México, con lo cual se evidencian las innovaciones y estrategias alimentarias a microescala, que son poco valorizadas fuera del ámbito local, debido al bajo capital tecnológico y digital para la difusión de sus alcances. Los resultados presentan rasgos particulares sobre la revalorización de los espacios ecológicos y ociosos en áreas urbanas, así como sobre la construcción de formas diferenciadas de habitar los contextos urbanos y sobre el modo en el que se teje el sentido de pertenencia de una comunidad que recupera los recursos territoriales a través de reconocer momentos críticos que influyen en la reinvención de prácticas y en la generación de estrategias de apoyo mutuo.Abstract: The main objective of the present paper is to address the function of urban agriculture as a practice of appropriation of urban space and community construction aimed at generating local food. The text analyzes a triple case study in which qualitative techniques were applied in popular peripheral areas to the east of the metropolitan area of Mexico City, which shows the innovations and food practices on a micro scale that are little valued outside of the local sphere due to the low technological and digital capital for the spreading of their scope. The results present particular features on the revaluation of idle spaces and ecological reserves within urban areas, as well as the construction of differentiated ways of inhabiting urban contexts and the way in which the sense of belonging of a community that recovers territorial resources is woven through the recognition of critical moments that influence the reinvention of practices and the generation of mutual support strategies.Keywords: agriculture; local; urban; popular neighborhoods; territory.Résumé : Cet article o pour objectif l’analyse des pratiques de l’agriculture urbaine, entendues comme une forme d’appropriation de l’espace urbain et de la construction communautaire visant à établir des réseaux d’alimentation.

Full textAbstract:
Restricted by urban development stages, natural conditions, urban form and structure, diffusional growth occupies a large proportion of area in many cities. Traditional cellular automata (CA) has been widely applied in urban growth studies because it can simulate complex system evolution with simple rules. However, due to the limitation of neighborhood conditions, it is insufficient for simulating urban diffusional growth process. A maximum entropy mode was used to estimate three layers of probability spaces: the probability layer of cell transformation from non-urban status to urban status (PLCT), the probability layer for aggregated growth (PLAP), and the probability layer for diffusional growth (PLOP). At the same time, a maxent category selected CA model (MaxEnt-CSCA) was designed to simulate aggregated and diffusional urban expansion processes simultaneously. Luoyang City, with a large proportion of diffusional urban expansion (65.29% in 2009–2018), was used to test the effectiveness of MaxEnt-CSCA. The results showed that: (1) MaxEnt-CSCA accurately simulated aggregated growth of 47.40% and diffusional growth of 37.13% in Luoyang from 2009 to 2018, and the overall Kappa coefficient was 0.78; (2) The prediction results for 2035 showed that future urban expansion will mainly take place in Luolong District and the counties around the main urban area, and the distribution pattern of Luolong District will change from the relative diffusion state to the aggregation stage. This paper also discusses the applicable areas of MaxEnt-CSCA and illustrates the importance of selecting an appropriate urban expansion model in a region with a large amount of diffusional growth.

It presents a diagnosis and mapping of COVID-19 cases and deaths from April 2020 to March 2021, apex of the epidemiological crisis in Brazil and also in this region. A qualitative approach, survey, organization and systematization of data from COVID-19 in Minas Gerais was used, in addition to analytical and graphical cartographic products. Regarding the analysis of the spread of the virus, the concept of urban networks with the expansion of spatial interactions is important for understanding the dynamics of the pandemic. The analysis points out that with the pandemic, displacements to Montes Claros and other micro-regional headquarters ratify the population's unequal access to highly complex health structures, and also reflects the rapid process of spreading the virus in northern Minas Gerais from the urban network.Keywords: Urban Network; COVID-19; North Macroregion.RESUMENEste texto analiza el proceso de difusión espacial de COVID-19 en la Macrorregión de Salud Norte de Minas.

Full textAbstract:
The Muslim holy city of Touba, self-defined ‘capital’ of the Murid Sufi order in Senegal, is increasingly thriving on its global connectedness. This article situates the phenomenon of Touba’s globalisation within current literature on the global city and world city networks. It assesses four of the processes through which the holy city’s values and structures are diffusing across the global North. First, the universality of Touba in Murid historiography is considered. Secondly, the diffusion of the toponym ‘Touba’, through the naming of expatriate associations and institutions, is analysed. Thirdly, the types and distribution of businesses set up in the US by Murids is assessed. Fourthly, the diffusion of typical Murid images is discussed as they too contribute to Touba’s international renown.

The emergence of graffiti's urban subculture as a means of political expression has become a singular issue of the so-called Arab Spring. Graffiti and urban art, which had little to no relevance in the Arab world until now, emerged with unusual force in many countries, notably in the Palestinian territories, Lebanon, and Egypt. This blossoming takes shape in tangent with the strengthening of a civil society and its rise as a decisive actor in the new political arena. In Egypt's case, graffiti achieved a leading role that reflected the milestones of civil disturbance, marking the walls with virtual snapshots of the popular sentiment. The proliferation of graffiti also had considerable resonance in international media because of the strategy of spreading rebellious and subversive slogans by means of the symbolic occupation of a public space, which, until now, was monopolized by authoritarian powers.Spanish Un fenómeno singular de la denominada “Primavera Árabe“ ha sido la eclosión de la subcultura urbana del graffiti como medio de expresión política. De escasa o nula relevancia hasta ahora, el arte urbano de las pintadas ha surgido con una fuerza inusitada en varias zonas del mundo árabe, notoriamente en los Territorios Palestinos, el Líbano y Egipto. Dicho florecimiento cuaja en paralelo con la rearticulación de la sociedad civil y su irrupción irreversible como actor de los nuevos escenarios políticos. En el caso de Egipto, los graffitis han tenido un señalado protagonismo como reflejo de los sucesivos hitos de las revueltas, marcando los muros y paredes con verdaderas instantáneas del sentir popular. La proliferación del graffiti ha tenido asimismo una considerable resonancia en los medios internacionales, debido a la estrategia de ocupar simbólicamente el espacio público, -que hasta ahora estaba reservado al monopolio de los poderes autoritarios- para la difusión de consignas contestatarias y subversivas.French Un phénomène singulier de la “printemps arabe“ a été l'émergence de la culture urbaine du graffiti comme un moyen d'expression politique. Avec peu ou pas d'importance jusqu'à ce jour, l'art urbain et le graffiti ont émergé avec une force inhabituelle dans diverses régions du monde arabe, notamment dans les Territoires Palestiniens, le Liban et l'Égypte. Ce e éclosion doit être mise en parallèle avec le renforcement de la société civile et son émergence comme acteur décisif dans le nouveau scénario politique. Dans le cas de l'Égypte, le graffiti a joué un rôle clé comme reflet des jalons successifs des révoltes, en marquant les murs avec des instantanés virtuelles du sentiment populaire. La prolifération des graffitis a rencontré aussi un écho remarquable dans les médias internationaux en raison de la stratégie d'occupation symbolique de l'espace public pour la diffusion des slogans rebelles et subversifs; un espace public qui était réservé jusqu'à aujourd'hui aux pouvoirs autoritaires.

Scopo di questo intervento è esaminare le principali testimonianze sulla diffusione dei culti in ambito rurale ed urbano nella Bitinia ellenistica e romana. Il dossier epigrafico appare più limitato per il periodo ellenistico, mentre è più ampio per quello romano. Nelle aree urbane e nelle aree rurali appaiono diffuse le principali divinità del pantheon cultuale greco come Zeus, Apollo, Artemide, Atena, Asclepio ed altre; è significativo come tali divinità nelle aree rurali appaiano con epiteti locali di origine indigena. Particolarmente interessante il caso di Zeus a cui sono associati epiteti come Baleos e Okkonenos, che appaiono di origine tracia, e come Sabazios, che è probabilmente di origine frigia. Altri culti probabilmente basati sulla commistione tra elemento greco e elementi non-greci erano quello della Grande Madre Cibele, che aveva un tempio dedicato a Nicomedia, e alcuni culti tipicamente locali come Priettos, Tataula, Proustene e i Theoi Nerolenoi. In ambito urbano possono ritrovarsi invece culti maggiormente legati alle influenze esterne come quelle egiziane. Ciò appare soprattutto nelle città costiere come Kios, Apamea e Nicomedia, che già in età ellenistica sono aperte ai culti di Iside e Serapide. Più limitato e in epoca più tarda appare l’influsso della religione romana, testimoniato dalle rare dediche bilingui e dall’attestazione dei riti funerari dei Rosalia. Il rapporto tra culti rurali e culti urbani appare contraddistinto quindi da alcune differenze, con le aree rurali che appaiono almeno in un primo tempo meno disponibili ad accogliere i culti stranieri e maggiormente legate ai culti indigeni, che vengono uniti a quelli per le principali divinità del pantheon ellenico. Alla fine tuttavia anche in Bitinia quindi, come è stato notato per altre zone dell’Asia Minore, si assiste, con il passaggio tra l’età ellenistica e quella romana, ad un processo di progressiva integrazione tra culti urbani e rurali, che si attua probabilmente in maniera prevalentemente armonica e senza grosse tensioni tra le varie componenti etniche e territoriali.

Full textAbstract:
Under the premise of controlling the external input of nitrogen and phosphorus, endogenous release is the main cause of eutrophication in lakes. To investigate the characteristics of endogenous nitrogen and phosphorus release from urban rivers, the Yitong River, an urban river in northern China, was used as an experimental object. Eight sampling sites were set up in the upstream, urban, and downstream regions of an urban section. The nitrogen and phosphorus nutrient exchange fluxes at the sediment-water interface of the Yitong River were assessed by analyzing the sediment and overlying water, and the effects of environmental factors on nitrogen and phosphorus release were investigated using static release experiments. The results showed that the diffusive fluxes of endogenous total nitrogen (TN), ammonia nitrogen (NH4+-N), and total phosphorus (TP) in the urban section of the Yitong River ranged from −1.571 to 19.365 mg·(m2·d)−1, −0.171 to 9.227 mg·(m2·d)−1, and −0.052 to 0.595 mg·(m2·d)−1, respectively. The diffusive fluxes of nitrogen and phosphorus nutrients were all greater under anaerobic conditions than under aerobic conditions. The diffusive fluxes of nitrogen and phosphorus were influenced by changes in pH, DO, and temperature of the overlying water, and the release of phosphorus from the sediment was accelerated by high temperatures in the range of 5–25 °C. Acidic conditions favored the release of TN, whereas alkaline conditions favored the release of TP from the sediment. Furthermore, during the control of nitrogen and phosphorus pollution, it should be noted that fluxes are higher in spring and autumn. Thus, when appropriate techniques should be implemented to achieve better control. These findings are intended to provide a reference for the study of nitrogen and phosphorus diffusion fluxes at the sediment-water interface in urban rivers and other surface waters around the world.

Full textAbstract:
Urban water scarcity has been an issue for a long time in China while water pollution has attracted more and more attention over the last two decades. Recently, on-site wastewater treatment (OST) has been proposed as a meaningful alternative to deal with both water pollution and water scarcity in cities in a more sustainable way. However, the diffusion of such an OST system is still slow and often hindered by mismatched regulation, city planning and policy interventions. This paper is intended to explore potential solutions from institutional and governance perspectives. Based on expert interviews and in-depth analysis of an OST system in Kunming, an improved trajectory for diffusing OST in urban China is developed, which includes reformed decision-making and operational procedures, role transition of relevant stakeholders, and improved financing mechanisms. The results might give some suggestions for the transition of urban water management in other newly industrializing countries.

Full textAbstract:
With the advancement of urbanization, the contradiction in the man–land relationship becomes more and more difficult to ignore. Investigation of the change in urban land use, population distribution and its mechanism can provide powerful assistance for urban planning. Since the changes in urban land use and population distribution is a complex process with spatial heterogeneity, the current methods for describing them are still lacking in both interpretability and spatial differences. In this paper, we combine the expansion phenomena of urban land use and population distribution with the heat equation to understand the mechanism. The particle swarm optimization (PSO) algorithm is used to identify the diffusion coefficient to obtain the diffusion law in the city’s development. In this way, the diffusion coefficient identified from the data is directly associated with urban changes. The mechanism of changes in urban land use and population distribution can be explained with the diffusion equation and the diffusion coefficient. Our model is first validated on land use and land cover data, followed by further refinement of the spatial differences in the artificial impervious surface data. The experiment’s results imply that by applying the model to the population data, the model’s generalization ability has been significantly improved.

Full textAbstract:
A simple, cost-effective diffusive sampler is described that is suitable for measuring parts per billion (ppb) levels of ozone and nitrogen oxides. The diffusive sampler makes use of nitrite for ozone determination whereas for nitrogen oxides and nitrogen dioxide an active carbon tissue impregnated with sodium carbonate is used. Nitrate and nitrite, the formation of which is proportional to the pollutant concentration and sampling duration, are the two species analysed, respectively. Diffusion tubes have the advantage of being a low- cost, convenient way of mapping spatial distributions and investigating long-term trends of ozone and nitrogen oxides. The method is extremely useful for assessing long-term concentrations such as the annual mean for nitrogen oxides, as required by the Daughter Directive 1999/30/EC. Field tests to validate the method have been carried out at an urban background location with co-located passive samplers and continuous measurements of O3and NOx. An application in ecological effects monitoring for ozone is also presented.

Full textAbstract:
This article focuses on the circulation of urban policy “models” and its influence on the reshaping of relationships between State and cities in France. It suggests that the increasing mobility of practices and knowledge between cities cannot be explained solely by the intensification of horizontal exchanges involving city halls throughout Europe. It also relies on the restructuring of the State and the transformation of its intervention in urban policymaking processes. By considering the Programme National de Rénovation Urbaine and the Plan Ville Durable, the article highlights the emergence of a new model of State–cities relationships characterized by the tracking of local “exemplary” initiatives, and by their certification and diffusion by the central State itself. This new model of relationships allows the State to strengthen its capacity to steer urban policies at a distance, without actually challenging the rise in power of French cities.

Il presente contributo propone una riflessione teorico-metodologica sulla mobilitŕ di gruppi sociali emergenti a partire dalla lettura di alcuni dati concernenti l'aumento generalizzato degli spostamenti nel nostro paese. La mobilitŕ come esito e fonte di pratiche specifiche di vita riguarda, infatti, un numero crescente di persone e rappresenta un aspetto rilevante nella vita quotidiana di ciascuno. Ciň rende sempre piů necessario delineare, anche attraverso l'analisi sociologica, modelli interpretativi precisi, costruiti in base alle caratteristiche socio-economiche e culturali degli individui oltre che alle loro motivazioni agli spostamenti. La diffusione degli spostamenti quotidiani effettuati per ragioni diverse che per viaggi di lavoro o vacanza interessa vari tipi di popolazioni contribuendo peraltro a trasformare la mobilitŕ da esperienza eccezionale a momento di routine. Questa larga diffusione del fenomeno chiama in causa a maggior ragione proprio quei segmenti sociali che hanno fatto della mobilitŕ e della transitorietŕ residenziale i loro punti di forza nelle societŕ contemporanee. Tra questi troviamo sicuramente la cosiddettacostituita da soggetti altamente mobili e per i quali nell'articolo si cercherŕ di individuare le traiettorie possibili di mobilitŕ alla luce della concentrazione territoriale di forza lavoro e utenti riconducibili a determinati settori e servizi culturali.

Simulating and predicting the development and changes in urban land change can provide valuable references for the sustainable development of cities. However, the change process of urban land-use/land-cover is a complex process involving multiple factors and multiple relationships. This dilemma makes it very challenging to accurately simulate the results and to make predictions. In response to this problem, we started with the physical characteristics of the land-use/land-cover change process and constructed a diffusion equation to simulate and predict urban land-use/land-cover changes. The diffusion equation is used to describe the diffusion characteristics of the land-use/land-cover change process, which helps to understand the urban land-use/land-cover change process. The experimental results show that (1) the diffusion equation we constructed can simulate urban land-use/land-cover changes, (2) the simulation process of the model is not limited by the time interval of the time series data itself, and (3) the model only requires one parameter without other constraints.

Full textAbstract:
This paper explores how the European Commission promotes the concept of Sustainable Urban Mobility Planning (SUMP) among European cities. Despite the strong uptake of the SUMP concept, mobility-related problems persist in European municipalities. Linking theoretical approaches to understand the diffusion of policies with empirical findings from working with cities in the SUMP context, this article explores channels of policy diffusion and investigates shortcomings related to the respective approaches. Studies on the diffusion, the transfer and the convergence of policies identify formal hierarchy, coercion, competition, learning and networking, and the diffusion of international norms as channels for policy transfer. The findings which are presented in this paper are twofold: First, the paper finds evidence that the Commission takes different roles and uses all mechanisms in parallel, albeit with different intensity. It concludes that the approaches to explain policy diffusion are not competing or mutually exclusive but are applied by the same actor to address different aspects of a policy field, or to reach out to different actors. Second, the article provides first evidence of factors that limit the mechanisms’ abilities to directly influence urban mobility systems and mobility behaviour.

Abstract Presentation of the current state and development tendencies of Jewish urban settlement in Israel against the innovation diffusion theory. Analysis of the growth tempo of the number of cities in Israel allows to claim that urban Jewish settlement network develops in accordance with the innovation diffusion model. Assuming that the theory fits the urban settlement development pattern on the surveyed territories, the directions taken by the impulses sent by innovation sources have been determined based on the corridor settlement development theory. The hypothesis has been verified against the factors influencing spatial development directions of the Jewish urban settlement using a dynamic (synchronic-comparative) diffusion process simulation model, built with the Monte Carlo method. The conducted analyses and procedures verifying the model distribution of Jewish settlement in Israeli cities in 1948, 1967 and 1992 allowed to conclude that the highest stochastic concordance between the model accounting for the innovation diffusion theory elements, and the real distribution of Jewish settlement cities holds for 1948 and 1967. According to the diffusion innovation theory, these years correspond to the colonisation stage. The model diversifies from reality for late 1967, when network densification process was coming to an end and city competition stage was starting. Despite statistical validity of the hypotheses, the results show that besides the analysed factors influencing the development of Jewish urban settlement, other variables, not accounted for in the model, are also significantly influential.

Literature suggests that the penetration of digital technology may create a digital divide, particularly for groups that lack resources and the capacity to access technology. This study is keen to examine the poverty and digital divide, particularly in urban poor areas. There are two research objectives. Firstly, to examine the digital diffusion and digital literacy within poor urban neighborhoods in the City of Magelang, Central Java, Indonesia. Secondly, to understand the variation of digital diffusion and digital literacy across areas (with different levels of poverty), age groups, genders and occupations. The data is collected from surveys focused on measuring the access to information, digital diffusion and the use of technology among the poor. This study found that there is a digital divide problem among people in urban areas, especially among people with low incomes. Moreover, the diffusion is dominated by certain groups such as younger people and females. Furthermore, digital literacy among the poor is low. The policy implication is to improve access for digital diffusion and provide assistance to improve digital literacy skills.

Full textAbstract:
A diffusive gradient in thin films (DGT) technique was employed in characterization of the particulate matter related to the urban area suffering from heavy traffic. Kinetics of mobilization metals fluxes from the metal-contaminated particulate matter was investigated. To monitor responses of the particulate matter sample, DGT probes of various thickness of diffusion layer were deployed in aqueous model suspensions of the particulate matter for different time periods. Particulate matter samples and exposed DGT resin gels were decomposed in a mixture of nitric and hydrochloric acid in a microwave pressurized PTFE-lined system. Total content of some traffic-related elements (Cd, Co, Cu, Mo, Ni, Pb, Pd, Pt, Rh, Sb, and V) was determined by inductively coupled plasma mass spectrometry. DGT measurements revealed that two metals pools associated with particles could be recognized, which can be characterized as high soluble fraction and almost insoluble fraction. DGT-measured metal fluxes from the labile pool showed significant difference in mobilization and resupply fluxes of individual selected elements, which might reflect the origin of selected metals and their speciation in particulate matter. The DGT technique can be applied as a useful tool for characterization of metals mobilization from the particulate matter.

Although building information modeling (BIM) has demonstrated to be an effective tool for the construction of urban rail transit worldwide, it has not gained the same popularity in the facility management (FM) of urban rail transit. The objective of this study is to investigate the BIM application areas for FM in urban rail transit from an innovation diffusion theory perspective, in order to gain efficient operation and maintenance (O&M) in urban rail transit. A total of 18 BIM application areas were first identified through semistructured interviews. A questionnaire survey was then conducted to further quantitatively characterize the relative advantage, ease of use, trialability, observability, and compatibility of these areas. Statistical analysis of the survey results provided evidence that, currently, BIM application areas directly related with facilities and equipment are most likely to be adopted. Correlation analysis further indicates that the perceived innovation diffusion characteristics of these BIM application areas significantly correlate with the development level of urban rail transit in different regions. The findings contribute to a broadened understanding of the complex innovation diffusion process of BIM for FM in urban rail transit and provide insights into how BIM can be more effectively adopted in the domain.

Mais les conséquences les plus caractéristiques du renforcement des services aux entreprises à l'échelle des villes moyennes concernent le fonctionnement territorial du réseau urbain. Si les modèles de gravitation et de hiérarchie urbaine restent encore vivaces, le déploiement des services aux entreprises introduit des processus de concentration sectorielle et des logiques d'interrelations entre les villes moyennes elles-mêmes.

Cities are characterized by concentrating population, economic activity and services. However, not all cities are equal and a natural hierarchy at local, regional or global scales spontaneously emerges. In this work, we introduce a method to quantify city influence using geolocated tweets to characterize human mobility. Rome and Paris appear consistently as the cities attracting most diverse visitors. The ratio between locals and non-local visitors turns out to be fundamental for a city to truly be global. Focusing only on urban residents' mobility flows, a city-to-city network can be constructed. This network allows us to analyse centrality measures at different scales. New York and London play a central role on the global scale, while urban rankings suffer substantial changes if the focus is set at a regional level.

God bless my soul, sir … I am all out of patience with the march of mind. Here has my house been nearly burnt down, by my cook taking it into her head to study hydrostatics, in a sixpenny tract, published by the Steam Intellect Society, and written by a learned friend who is for doing all the world's business as well as his own, and is equally well qualified to handle every branch of human knowledge. [Thomas Love Peacock—Crotchet Castle (1831)]The diffusion of knowledge preoccupied middle-class elites in early industrial England. While factory production promised a future of material abundance, an unsettled and menacing social environment threatened this vision of endless progress. Education constituted a cornerstone of the liberal creed embraced by the industrial middle class, and diffusing knowledge offered the hope of raising up the “lower orders” to social responsibility and respectability. A properly arranged distribution of knowledge held out hope for an ordered and orderly social existence.But the diffusion of knowledge meant more than simply uplifting the working class. Its significance extends beyond the problematic historical question of “social control.” An utterly new society was rising in the industrializing urban agglomerations of provincial England. An expanding middle class of businessmen and professionals claimed this world as its own. They pursued political power on both local and national stages and fought for reform in economic and social policy. A strongly felt sense of stewardship prompted the industrial middle class to devote great resources and energies to shaping the new urban environment.
