Regional Specialization of Greek Prefectures for the Time Period 1981-2001
Get PDFIntense regional inequalities are considered to be widespread in Greece. Indeed, Athens mainly, and Thessaloniki consist the two poles in Greece, Thessaloniki in a lower degree though. In these two cities the larger part of industrial activity, as well as, tertiary sector activities, is assembled. On the contrary, in the other Greek regions not only the economic activities but also the infrastructures have been developed in smaller degree. Moreover, as it is well known, two Greek regions (Northern Aegean, Epirus) are among the poorest in the European Union. This fact constitutes a reluctant factor to the effort of Greece to increase the standard of living of the citizens. In addition, the last two decades, a significant decrease of the contribution of primary sector to the GDP with simultaneous increase of the contribution of the tertiary sector is observed. The particular change involves significant repercussions to the national economy. The aim of this paper is the study of the specialization of Greek prefectures as well as spatial distribution of 13 sectors of economic activity using employment data and methods of regional analysis such as Gini – Hirschman coefficient, Location Quotient Coefficient (LQ), Coefficient of Location (CL), Coefficient of Specialization (CS) and analysis of variation – participation.
EMPIRICAL DEMAND ANALYSIS FOR LONG - LENGTH ROUNDWOOD (SAWLOGS) IN GREECE
Get PDFIn Greece and internationally, the roundwood is one of the most important forest products as it is used widely in construction and building sector. In this study the process of wholesale long-length roundwood (>2m) price determination is depicted in the form of an inverse demand system. The empirical application based on five species of long-length roundwood using yearly data for auctions providing reasonable and promising results. The own-quantity flexibilities suggest that the responses of prices to own-quantity changes are inelastic while Allais coefficients suggest substitutability between the different species of log-length roundwood.Inverse Almost Ideal Demand System, demand analysis, flexibilities, long-length roundwood, wood sector, Greece
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
