Defining region

Regional studies are right in the center of scientific and political discourse at the moment; regional issues acquire special significance in the countries with a transition economy. However, there is still no clear definition of the term “region”. Due to its multifaceted nature, it certainly has natural, cultural, economic, political, and social dimension. At the same time, this term occupies a wide range of phenomena from small parts of countries to huge continental interstate formations. The goal of this paper is the analysis of various theoretical and methodological approaches to the definition of the region. We have brought different approaches, from the classical school to the New Economic Geography. The latter considers the region as a unit of space for economic activities. Thus, the region becomes a multidisciplinary object of research within the framework of economic theory and economic geography. In Europe, the integration processes put the region on the forefront of economic policy. The issues of regional policy are equally important in the light of the economic modernization processes taking place in Russia and Serbia. This article also summarizes the experience of regional studies of Serbian and Russian schools. The results can be used in further theoretical and applied research, writing theses in the field of economics and economic geography

Urban forestry

In the article the author investigate the urban forestry education in the world. As the results of the research he conclude that, new programs and approaches such as landscape ecology and management, sustainable land use, urban ecology, and urban agriculture all take a more integrative perspective on different land uses, land covers and ecosystems. Also he found out the in Russia urban forestry education is not presented and can be prospective for development.Исследуется образование в сфере городского лесного хозяйства в мире. По результатам исследования автор пришел к выводу, что новые программы и подходы, такие как ландшафтная экология и управление, устойчивое землепользование, городская экология и городское сельское хозяйство, имеют отношение к различным видам землепользования, земельным покровам и экосистемам. Показано, что в России образование в сфере городских лесов не представлено и может быть перспективным

The role of human resources on the economy: a study of the Balkan eu member states

In this paper we analyze the impact of the quality of human capital on the main economic indicators of South-Eastern Europe countries [SEE] at the NUTS 2 level. The subjects of this research are the human capital indicators of regional competitiveness. The quality of human capital depends largely on the age structure of the population and the quality of education. Those regions, which have the highest percentage of the working-age population and highly educated people, are able to achieve higher productivity and gain a competitive advantage over other regions. As main indicators of the quality of human capital we identified: population; persons aged 25-64 with tertiary education attainment; students in tertiary education and participation of adults aged 25-64 in education and training and human resources in science and technology. As main economic indicators, we identified: regional gross domestic product; employment and income of households. The aim of this paper is to determine whether there is a correlation between the indicators of the quality of human capital and economic indicators. As a main methodology we have used the correlation coefficient which shows interdependence of the analyzed indicators. As part of our analysis, we consider only EU member states that belong to the SEE countries: Slovenia, Croatia, Romania, Bulgaria and Greece. We conclude that in all countries there is a high multiple correlation coefficient between the indicators human resources in science and technology, number of students and employment.This paper is the result of the project No. 47007 III funded by the Ministry for Education, Science and Technological Development of Republic of Serbia

Visual perception specifics of children with ASD as a determinant for educational environment outlinetimes

The idea of inclusive education raises the question of security of children with autism spectrum disorders (ASD). It is the imperative of the time to create teaching materials that promote the effective implementation of educational curriculum. However, we have to stress the fact that most of the evaluable nowadays teaching materials have been created spontaneously, without any reliable criteria. Our primary hypothesis is that children with ASD have specific features of visual perception that do not depend on the state of their intelligence, which is confirmed by empirical data obtained by the authors. Our secondary hypothesis, specified in the process of research, stipulates that children with ASD will differently perceive different graphic images executed in different styles. These findings are further confirmed by empirical data collected by the authors in the study of perception and understanding of different graphic images by children with ASD and mental retardation. On the basis of theoretical and empirical data we specified the criteria for graphic design products which play a pivotal role in the formation of school educational environment. In this respect we focus on the criteria for design materials (including design criteria provisions, formulated by Norman, which he addressed to practicing designers). © 2017 IJCRSEE.

Statistical territorial units with purpose of measuring level of development of regions in Serbia

Дан общий обзор существующей классификации статистических территориальных единиц в соответствии с классификацией NSTJ в Сербии. Цель работы - изучить и проанализировать классификации NSTJ в Сербии и определить, соответствует ли она классификации в ЕС. Сформирован перечень возможных мер, которые государство должно предпринять для того, чтобы выровнять степень развития регионов. Рассмотрены возможности использования имеющихся ресурсов. Установлено, что Сербия не имеет региональной политики, целью которой было бы выравнивание регионов и управление их более равномерным развитием в Сербии, как это предусмотрено Конституцией. После распада Югославии в 1991 году Сербия становится одной из европейских стран с крупнейшимими различиями в развитии регионов

A Complex Domain Mapping of the SCN for an Effective PML Implementation in TLM

An improved implementation of the perfectly matched layer (PML) is developed for the Transmission Line Modelling (TLM) method based on a mapping of the symmetrical condensed node (SCN) to an analytically extended geometric space. By mapping the TLM node, a medium — circuit equivalence is developed which maps transmission line parameters from real to complex domain. This consequently modifies the TLM scatter-connect process. The PML implementation is demonstrated for canonical cases where it is shown to have a comparable absorption performance and a significantly improved temporal stability relative to previously published TLM-PML formulations

Parity-time chain of whispering-gallery mode resonators

The paper analyses the dispersion characteristics of an infinitely long PT chain made of whispering gallery resonators with gain/loss modulation. The results show that the appearance of the threshold breaking point depends not only on both of coupling and gain/loss modulation but also on the Bloch phase. The Bloch phase is seen as an additional parameter that can reduce or even completely eliminate PT-breaking threshold

Coupled parity-time symmetric cavities: results from transmission line modelling simulations

This paper studies the impact of a dispersive gain/loss material model on Parity-Time (PT) coupled microresonator cavity structures using the time-domain Transmission-Line Modelling method. A modal analysis is also performed to compare the modal composition in the dispersive and non-dispersive cases. Furthermore, a waveguide-to-waveguide coupler based on the coupled PT-resonant microresonators is analysed to see how the resulting modal profiles are manifested in the power transmitted between input/output ports

Threshold manipulation in parity-time symmetric microresonator chain

This paper analyses the eigenfrequencies of an infinitely long chain of microresonators with PT symmetry. The results show that the depth of modulation of the real part of the refractive index can be used to control the threshold point of the PT structure
