Modelling suburbanization (success and limits of microeconomics of cities)
2001
History of population and employment suburbanization, mainly in the United States, suggests three characteristics of the phenomenon. 1/ Suburbanization results in urban sprawl in such a way that population and employment increase more rapidly in the periphery than in thecenter. 2/ Suburbanization leads to the emergence of new activity centers in the periphery and gives rise to multicentric urban structures. 3/ Suburbanization différenciâtes the economic contents and functions of these activity centers and brings a new organization of urban centres.In this framework, suburbanization takes different forms depending of periods and regions. The emergence of centers and the transformation from m…
Si j'aurai su, j'aurai pas venu" : éclairage stratégique sur le lancement simultané des deux " Guerre des Boutons "
2014
“If I knew, I will not come”: strategic insight on the simultaneous launch of the two Guerre des BoutonsThe purpose of this paper is to propose an insight on an unusual strategic situation in the movie industry: thesimultaneous launch on screens of two almost identical movies, La Guerre des Boutons. After recalling the stakesattached to the product launch in the film industry, a monograph devoted to this direct confrontation, supplementedby an analysis of the critics of spectators, is proposed. This analysis reveals determinants (the conflictand lack of control in the film industry) and consequences (sub-optimal strategy) of the temporal agglomeration.
Realization of Regional Operational Programme of the Opolskie Voivodeship 2014-2020. Assumption and Activities In the Opole Agglomeration in the Cont…
2019
Celem artykułu jest identyfikacja i ocena działań mających wpływ na rozwój aglomeracji opolskiej na gruncie koncepcji zrównoważonego rozwoju. Istotne jest zidentyfikowanie działań podejmowanych w zakresie prowadzonej polityki w ramach istniejącego obszaru funkcjonalnego oraz ich ocena w kontekście założeń zrównoważonego rozwoju. Aby zrealizować tak określony cel, analizę oparto na typach projektów finansowanych w ramach RPO WO 2014-2020 oraz zasięgu ich oddziaływania. W rozważaniach uwzględniono trzy główne aspekty rozwoju zrównoważonego: ekonomiczny, społeczny oraz środowiskowy. Ponadto starano się zidentyfikować korzyści płynące z prowadzonych przez Stowarzyszenie Aglomeracji Opolskiej dz…
Iron oxide-based magnetic photocatalysts: Recent developments, challenges, and environmental applications
2021
Abstract Magnetic separation of the solid photocatalyst from the reacting suspension has received great interest in recent research because it offers a suitable way for removing and recycling the heterogeneous photocatalytic material particles preventing the agglomeration and sedimentation during and after their use. The use of iron oxides such as heterogeneous photocatalysts is an appropriate choice to obtain a suitable photocatalyst easily separable from the fluid. This chapter presents a detailed investigation of iron oxide-based magnetic photocatalysts (IOMPs). We will discuss the required conditions for the synthesis of these photocatalysts, followed by their applications for the remov…
Modelling Monomer/Disc Composites Phase Behaviour
2012
Summary: A model developed by Balazs' group to explain the phase behaviour of polymer/clay composites is extended to obtain an expression for the free energy of polymer/thin disc mixtures. Phase diagrams for monomer/disc mixtures are built by minimizing the free energy and calculating the chemical potentials of the three system components. Via the comparison of the diagrams, it is studied the effects of nanodisc size and interaction parameters on mixture stability and attained morphology. The performed predictions between monomers and discs give criteria that advance the properties of the mixture. Changes in monomer concentration and interaction parameters provide a means to prevent van der…
Urban Growth and Real Estate Income. A Comparison of Analytical Models
2016
I processi di crescita urbana sono notoriamente complessi dipendendo da un’ampia varietà di fattori demografici, socio-culturali ed economici. L’analisi è ancora più complessa nelle aree metropolitane che sono il risultato di antichi processi di agglomerazione in una fase d’intenso accrescimento dell’insediamento e, più recentemente, della formazione di policentrismo urbano. L’investigazione richiede l’acquisizione, l’analisi e l’elaborazione d’idonee informazioni a livello delle unità territoriali omogenee, basandosi su modelli consolidati o su nuovi protocolli da verificare. Il presente contributo analizza la crescita urbana secondo un approccio di piccola scala, individuando i distretti …
URBANIZATION PROCESSES AND ITS SPECIFICS IN LATGALE
2010
<p>Urbanization is an important demo-geographical process and a complex social phenomenon under impact of which changes are made not only to the global, regional or national settlement systems, but all socio-economic processes are also substantially transformed. Changes caused by urbanization have an impact on traditional way of life, cultural particularity, community and individual psychology and other aspects of spiritual life, therefore expressions and regularities of this process might be of interest not only for demographers, geographers and economists, but also for representatives of the field of humanities.</p><p>Paper presents the progress of urbanization processes…
Drivers of Agglomeration: geography VS. History
2009
This paper focuses on the influence of two classical drivers of population agglomeration: geography and history. Geography is identified by two co-ordinates: coastal position and altitude. The prominence of history is also captured by two characteristics: the initial size of the municipalities, and their status as the administrative centre of the area. In first instance we examine localization patterns, at a small geographical scale, according to these characteristics and present empirical evidence of the progressive population concentration along the coast, on the plains and in the regional (provincial) capitals; a process that has not finished in the present days. Next, we show that both …
A Methodology for Comparing the Surface Urban Heat Island in Selected Urban Agglomerations Around the World from Sentinel-3 SLSTR Data
2020
[EN] Retrieval of land surface temperature (LST) from satellite data allows to estimate the surface urban heat island (SUHI) as the difference between the LST obtained in the urban area and the LST of its surroundings. However, this definition depends on the selection of the urban and surroundings references, which translates into greater difficulty in comparing SUHI values in different urban agglomerations across the world. In order to avoid this problem, a methodology is proposed that allows reliable quantification of the SUHI. The urban reference is obtained from the European Space Agency Climate Change Initiative Land Cover and three surroundings references are considered; that is, the …
The Impact of Green Roofs on the Parameters of the Environment in Urban Areas—Review
2019
This study presents the results of a review of publications conducted by researchers in a variety of climates on the implementation of ‘green roofs’ and their impact on the urban environment. Features of green roofs in urban areas have been characterized by a particular emphasis on: Filtration of air pollutants and oxygen production, reduction of rainwater volume discharged from roof surfaces, reduction of so-called ‘urban heat islands’, as well as improvements to roof surface insulation (including noise reduction properties). The review of the publications confirmed the necessity to conduct research to determine the coefficients of the impact of green roofs on the environment in the city c…
