The impact of the new airport of Athens on the land values of Eastern Attica

The analysis of the value of the area around "Eleftherios Venizelos", the new airport in Greater Athens area has been based on a survey of the international experience and followed by a quantitative data analysis. The figures of the database come from the Objective System of Assessment (O.S.A.) as well as the Relative Price System of the Local Revenue Offices (R.P.S.R.O.). The data was analysed according to the hierarchical tree method and there has been a detailed reference to the restrictions and the conditions of the data use. The analysis has been at a horizontal level, that is, we have tried to interpret the increasing decline between the O.S.A. or the R.P.S.R.O. prices and the real prices of land The ranking system has been based on the functionality of the specific areas. The analysis has been at a vertical level too, that is, a year by year analysis of the built-up areas which have been grouped geographically. These built-up areas come under the O.S.A. and R.P.S.R.O. systems. The analysis also, determines the perspective on the land use pattern of the study area.

Generalized h-index for Disclosing Latent Facts in Citation Networks

What is the value of a scientist and its impact upon the scientific thinking? How can we measure the prestige of a journal or of a conference? The evaluation of the scientific work of a scientist and the estimation of the quality of a journal or conference has long attracted significant interest, due to the benefits from obtaining an unbiased and fair criterion. Although it appears to be simple, defining a quality metric is not an easy task. To overcome the disadvantages of the present metrics used for ranking scientists and journals, J.E. Hirsch proposed a pioneering metric, the now famous h-index. In this article, we demonstrate several inefficiencies of this index and develop a pair of generalizations and effective variants of it to deal with scientist ranking and with publication forum ranking. The new citation indices are able to disclose trendsetters in scientific research, as well as researchers that constantly shape their field with their influential work, no matter how old they are. We exhibit the effectiveness and the benefits of the new indices to unfold the full potential of the h-index, with extensive experimental results obtained from DBLP, a widely known on-line digital library.Comment: 19 pages, 17 tables, 27 figure

The Hypanis fluvial deltaic system in Xanthe Terra: a candidate ExoMars 2018 Rover landing site

The search for life on Mars is a cornerstone of international solar system exploration. In 2018, the European Space agency will launch the ExoMars Rover to further this goal. The key science objectives of the ExoMars Rover are to: 1) search for signs of past and present life on Mars; 2) investigate the water/geochemical environment as a function of depth in the shallow subsurface; and 3) to characterize the surface environment. ExoMars will drill into the sub-surface to look for indicators of past life using a variety of complementary techniques, including assessment of morphology (potential fossil organisms), mineralogy (past environments) and a search for organic molecules and their chirality (biomarkers). The choice of landing site is vital if the objectives are to be met. The landing site must: (i) be ancient (≥3.6 Ga); (ii) show abundant morphological and mineral evidence for long-term, or frequently reoccurring, aqueous activity; (iii) include numerous sedimentary outcrops that (iv) are distributed over the landing region (the typical Rover traverse range is a few km, but ellipse size is ~ 104 by 19 km). Various ‘engineering constraints’ also apply, including: (i) latitude limited to 5º S to 25º N; (ii) maximum altitude of the landing site 2 km below Mars’s datum; and (iii) few steep slopes within the ellipse

The Palgrave Handbook of Development Cooperation for Achieving the 2030 Agenda

This open access handbook analyses the role of development cooperation in achieving the 2030 Agenda in a global context of ‘contested cooperation’. Development actors, including governments providing aid or South-South Cooperation, developing countries, and non-governmental actors (civil society, philanthropy, and businesses) constantly challenge underlying narratives and norms of development. The book explores how reconciling these differences fosters achievement of the Sustainable Development Goals
