Urban Development
No full textCities are growing as never before and nowadays, it is estimated that at least 50% of the world's population lives in urban areas. This trend is expected to continue and simultaneously the problems in urban areas are anticipated to have an increase. Urbanization constitutes a complex process involving problems with social, economic, environmental and spatial dimensions that need appropriate solutions. This book highlights some of these problems and discusses possible solutions in terms of organisation, planning and management. The purpose of the book is to present selected chapters, of great importance for understanding the urban development issues, written by renowned authors in this scientific field. All the chapters have been thoroughly reviewed and they cover some basic aspects concerning urban sustainability, urban sprawl, urban planning, urban environment, housing and land uses. The editor gratefully acknowledges the assistance of Dr Marius Minea in reviewing two chapters

Modelling the regional variability of building activity in Greece: A multi-level multinomial logistic regression approach
No full textThis paper studies spatial differences in the fluctuations of the regional building activity in Greece, by developing a composite multinomial logistic regression model expressing the building activity’s variability in socio-economic terms. The results show that the variability in building activity is related to economies of scale within the construction sector, along with the performance of two other Greek economy’s major sectors, i.e., tourism and tertiary, in highlighting a dependence on the prime drivers of economic and regional development. Overall, the research provides empirical evidence on the macro-economic modelling of spatial demand, based on a proxy incorporating all aspects of human activity in the geographical space
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Deforestation processes in Greece: A spatial analysis by using an ordinal regression model
No full textForest land use changes in Greece have been the outcome of combining forces with mostly economic and institutional origin. Interactions between the major land uses have diachronically resulted in spatial patterns of great economic and environmental interest. This paper aims at describing forest land use changes during the last decades in Greece as well as analyzing the major regional and economic development implications. Particular attention is given to the analysis of possible driving forces with economic and social origin. The estimations are carried out through the use of a statistical model that employs ordinal regression analysis. Ordinal regression is a variation of ordinary regression which is used when the dependent variable is categorical and the explanatory variables are continuous, or categorical. An advantage of this type of regression is that requires fewer assumptions as regards the relationship between the explanatory variables and the dependent variable. Assessing sustainability of development decisions on a regional scale through the evaluation of likely impacts on forest resources can provide great support in formulating better regional policies that incorporate the environmental protection objectives of the society.Deforestation Land use change Ordinal regression Greece
The Egnatia Motorway and The Changes in Interregional Trade in Greece: An Ex Ante Assessment
No full textThe Egnatia Motorway, located in the northern part of Greece, constitutes one of the most important, as well as ambitious, projects of the Trans-European Transport Networks programme (TETN) funded by the European Commission. It is expected to greatly influence the spatial economic relationships of several regions across the country. The motorway crosses all administrative regions of Northern Greece, and the expectations currently sustained by the public as regards its contribution to regional development are exceptionally great. As numerous empirical studies have already shown, the most important changes in regional economy induced by interregional transportation infrastructure are associated with trade flows between different regions. This paper analyses the major determinants of interregional trade in Greece and estimates the changes in interregional trade flows which the construction of the Egnatia Motorway is capable of generating
Examining the relationship between Tourism Seasonality and Tourism Carrying Capacity indexes for the Greek prefectures
No full textTourism seasonality and tourism carrying capacity are major issues in the study of the tourism phenomenon. Destinations with high values in related indexes are faced with tourism saturation and sustainability. Within this context, this paper examines the relationship between tourism seasonality and tourism carrying capacity of the Greek prefectures, on data referring for the year 2018. The analysis measures tourism seasonality based on the Relative Seasonal Index (RSI), while for measurement of tourism carrying capacity (TCC) used an index consisting of fourteen sub-indices. The two variables are examined by using statistical techniques to classify the Greek prefectures by their performance. In further analysis, is applying a simple linear regression and outlier cases identified. The overall approach proposes a useful quantitative tool for tourism management and regional development because it allows considering in common the temporal and spatial dimensions of the tourism seasonality phenomenon
Analysis of commuting in Attica
No full textMany complex systems are organized in the form of a network embedded in space. Networks appear naturally in many fields of science, and are often inherently complex structures. Many complex networks show signs of modular structure, uncovered by community detection. Communities allow researchers to understand better the network by reducing its complexity. This study analyzes the inter-regional commuting systems of region Attica in Greece, employing approach of detection of complex network communities. In particular, in this paper, the administrative units of Attica are presented as a complex network, using as a criterion for the existence of a functional relationship and the identification of network communities (FUAs) the daily commuting. Network communities are identified through the modularity maximization method used to analyze complex networks. In parallel with this, through regression model application, the main factors affecting the out-commuting intensity of the municipalities of Attica are defined. The conclusions reached are of special interest for Greece as commuting in this country has not been studied yet extensively
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
