Management elements of the emergent metropolitan areas in a transition country: Romania, as case study

Complex processes, specific to the countries in transition, have had major impacts on restructuring the territorial management systems. The removal of restrictions of limiting urban expansion, imposed by the totalitarian regime, has allowed the rapid expansion of cities, beyond administrative boundaries, since 1989. The concept of emerging metropolitan area is explained by the multitude of problems posed by the sketching of these areas and especially by their functioning. Synthesizing, there are presented some managerial experiences considered inchoate, of some emerging Romanian metropolitan areas, with an emphasis on Bucharest’s metropolitan area. The conclusions of these descriptive analysis show the complexity of the problems that can occur during the process of building of the metropolitan areas under the circumstances of lack of an inter-municipal cooperation culture. Integrated management takes into account two realities: firstly, that the management of emerging metropolitan areas is trans-scalar, achieving the partial mergence of the management types (including the collegiate one), and secondly, that insuring a multi-level governance without implementing a polycentric intra-metropolitan development policy, is not sufficient

THE ROLE OF POLYCENTRIC NETWORK IN THE DEMOGRAPHIC DYNAMIC OF HUMAN SETTLEMENTS

The present study is a concise form of some of the researches conducted within the Interdisciplinary Centre for Advanced Researches on Territorial Dynamics of the University of Bucharest, which had as an objective identifying the relationships between the development of the poles network and the evolution of demographic indicators. The study’s objectives are related to identifying the role of decisional impulses from the development poles level in the functional structuring of the local settlements system. The analyses were done at each census level, and the measures adopted by the decision makers in order to stimulate the economy of development poles were underlined. A special attention was given to the communist period, when decisional impulses were followed by immediate effects at the level of dissipative capacity of towns, towards which the investments allocated in order to develop industry were oriented

Health Tourism Contribution to the Structural Dynamics of the Territorial Systems with Tourism Functionality

AbstractThe study aims to identify the role of health tourism (SPA) in developing the territorial systems, characterized by the tourism functionality, in Romania, for the period 2000-2012, a period marked by spectacular transformations, especially for this economic sector. Tourism has now become a true economic engine, generating an increase in the functional complexity of the territorial system, which is based on exploiting tourism resources. To quantify how tourism has contributed to the economic development of these territorial systems in Romania a database of NACE codes was set up, specific for the tourism activity, for the period 2000-2012, for territorial mainframe systems with functionality resort. Based on this statistical support analyzes on the evolution of the number of companies, number of employees, turnover and profit were made. The results show the important role of health tourism in generating multiplier effects on other components of the economic subsystem. They were defined two categories of territorial systems: territorial systems where tourism plays a complementary role function and territorial systems in which health tourism has a preeminent role in the local economy

Using fractal analysis in modeling the dynamics of forest areas and economic impact assessment:Maramureș County, Romania, as a case study

This study uses fractal analysis to quantify the spatial changes of forest resources caused by an increase of deforested areas. The method introduced contributes to the evaluation of forest resources being under significant pressure from anthropogenic activities. The pressure on the forest resources has been analyzed for Maramureș County, one of the most deforested counties in Romania. In order to evaluate this, the deforested areas were calculated for the period of 2001–2014, by using the Global Forest Change 2000–2014 database. The Fractal Fragmentation Index (FFI) and Fixed Grid 2D Lacunarity (FG2DL) were used to quantify the degree of fragmentation and dispersion of the forested areas, and thereby the extent to which a forest area is affected by deforestation. The process of quantifying the pressure on forested areas included the creation of a database for the period of 2000–2014 containing economic activities (turnover) related to woody recourses, important indicators of forest exploitation. Taken together, the results obtained indicate a dramatic increase in deforested areas (over 19,122 ha in total for the period of analysis), in Maramureș County

Use of Fractal Analysis in the Evaluation of Deforested Areas in Romania

Spectacular spatial dynamics of forest areas is one of the biggest challenges for the scientific world, concerned with completing the methodologies devoted to new methodological approaches, to provide new information that is indispensable in assessing the impact of deforestation within the ecosystem. In this study, we analyzed the evolution of the deforested areas, using the fractal fragmentation index (FFI). The research is based on high-resolution satellite images of forest areas between 2000 and 2017. The use of fractal algorithms allowed the modeling of the grinding patterns, identifying obvious differences between compact and fragmented cuts. Information is needed especially in the evaluation of the areas cleared because of illegal actions. Research has shown spectacular increases in deforestation in the mountain area, the northern and central groups of the Eastern Carpathians being the most fragmented geographical regions in Romania. The study showed that deforestation led to the fragmentation of forests, which generates major natural changes. The results obtained can contribute to the identification of new approaches in national forest fund management policies by establishing a critical fragmentation threshold

Socio-economic Restructuring of the Mining Areas of Gorj County

Gorj County is lying on a surface of 5, 602 km² (about 2, 5% of the Romanian territory), on the banks of Jiu river (the middle reaches of the Jiu river), in the South-West region of Romania country and the North-West of the Oltenia land. Gorj County was founded in 1998 and is included in Oltenia South-West Restructuring Region, alongside of other four counties (Dolj, Vâlcea, Olt, Mehedinţi), one of the eight regions under restructuring process at the national level and which, from the territorial point of view, correspond to some territorial units, the so-called NUTS-II (The Nomenclature of Territorial Units for Statistics), according to EUROSTAT (European Distributors of Statistical Software) classification. Taking into account the relatively unstable structure and dimension, of the geographical space affected by the most significant human intervention into the national territory, the impact of diminished economic activities is extremely important. It is being noticed at regional and local levels, but also national one

Flood Hazard Mapping Using the Flood and Flash-Flood Potential Index in the Buzău River Catchment, Romania

The importance of identifying the areas vulnerable for both floods and flash-floods is an important component of risk management. The assessment of vulnerable areas is a major challenge in the scientific world. The aim of this study is to provide a methodology-oriented study of how to identify the areas vulnerable to floods and flash-floods in the Buzău river catchment by computing two indices: the Flash-Flood Potential Index (FFPI) for the mountainous and the Sub-Carpathian areas, and the Flood Potential Index (FPI) for the low-altitude areas, using the frequency ratio (FR), a bivariate statistical model, the Multilayer Perceptron Neural Networks (MLP), and the ensemble model MLP–FR. A database containing historical flood locations (168 flood locations) and the areas with torrentiality (172 locations with torrentiality) was created and used to train and test the models. The resulting models were computed using GIS techniques, thus resulting the flood and flash-flood vulnerability maps. The results show that the MLP–FR hybrid model had the most performance. The use of the two indices represents a preliminary step in creating flood vulnerability maps, which could represent an important tool for local authorities and a support for flood risk management policies

Prediction of the residual stress after quenching of 6061 aluminium alloy plates by using mathematical modelling

The purpose of this article is to better understand the behavior of the residual stresses in aluminium alloy plates by using mathematical modelling. Quenching of aluminium alloy plates causes an uneven temperature variation in aluminum alloy plates, and elastic and elasto-plastic deformations occur inside the material. The latter causing the formation of deformations and residual stresses. The non-linear thermo-mechanical direct coupled analysis of the quenching process for a 6061 aluminium alloy plate was achieved by using ANSYS finite element software. The residual stresses due to solid thermal effects were determined by calculation of the Third principal stresses, the most negative or compressive. The developed mathematical model offers a support in the understanding the behavior of the residual stresses in aluminium alloy plates and a better control of them

Caracteristicile sectorului antreprenorial din sistemele teritoriale emergente

Economic ventures concentrated inside these urban clusters in a short span of time, and they registered a spectacular evolution, compared to the neighboring areas. Intensification of the linkages between cities with more than 300,000 inhabitants in Romania and the surrounding areas led to the individualization of territorial systems apart, with a spectacular evolution of economic-social processes, which turn those systems into the most dynamic territorial structures. The present study means to identify the causes of those complex processes within emerging territorial systems, the manner of functional organization of the space, and the causes that determine the spectacular evolution of the economic processes within emerging systems. Special attention was paid to the implementation of infrastructure projects, and to the manner they influenced the dynamics of the entrepreneurial sector
