Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
New EU policy for coastal areas
No full textViene presa in analisi e discussa la politica marittima della UE.
“Europe is surrounded by many islands and by four seas: the Mediterranean, the Baltic, the North Sea and the Black Sea; and by two oceans: the Atlantic and the Arctic. This Continent is a peninsula with thousands of kilometres of coast - longer
than that of other large land masses such as the United States or the Russian Federation. This geographical reality means that over two thirds of the Union’s borders are coastal and that the maritime spaces under the jurisdiction of its Member States are larger than their terrestrial territory. Through its outermost regions, in
addition to the Atlantic Ocean, Europe is also present in the Indian Ocean and the Caribbean Sea. Their maritime stakes are many and concern the EU as a whole.” P3
“As the EU seeks to revitalise its economy, it is important to recognise the economic potential of her maritime dimension. Between 3 and 5% of Europe’s Gross Domestic
Product (GDP) is estimated to be generated by marine based industries and services, without including the value of raw materials, such as oil, gas or fish. The maritime
regions account for over 40% of GDP.
Sea management and the claim to jurisdictional zone: the Chinese Situation
No full textThe sea management requires a special attention to the relationship between the legal and geographic dimensions. The authority over the sea adjacent to the shoreline (coastline) of different countries has always been a difficult problem to face.
In the past centuries, the jurisdictional authority over the sea corresponded to a 3 nautical miles wide stretch in front of the shoreline of the interested country. It corresponded to the area that could be protected by guns situated on the shoreline.
In 1609 Grotins (NL), following the trend to explore new commercial lines, suggested the idea of “Mare libero” (freedom of the seas).
Up to the first half of the 20th Century, the utilisation of sea water depended on unilateral agreements among neighbouring countries.
After the end of the Second World War, a more exact and severe regulation concerning the sea control became necessary. This mainly depended on new economic needs and on a new possible utilisation of sea: delimitation and jurisdictional use of zones devoted to fishing and mining activities (oil field research), and of free passages devoted, like sea roads, to the international navigation lines.
From that time a series of international conferences followed, which aimed to promote a general law of the Sea (LOS) accepted by all the countries. At UN Assembly meeting in 1994, 85 countries accepted a version of the LOS identifying 4 different sea zones: 1) territorial sea waters up to 12 nautical miles from the shoreline; 2) the contiguous sea zone up to 24 n. m. from the shoreline; 3) the EEZ (exclusive economic zone) up to 200 n. m. from the shoreline and devoted to fishery or mining activities. In this wide area the passage of navigation lines is permitted only if “inoffensive” (no submarines or battle-cruisers); 4) international waters considered of common interest for the entire world (like the Antarctic territories) and not completely free
Variations on the Author
Full text link“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
Full text linkWe 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
Human interventions and alterations of the geomorphological characteristics in parts of the coastal area in the Ionian coasts (Ipiros-Greece)
No full textAccording to data results from in situ observations and the interpretation of aerial photography of the past, it arises that in general therms the state of the coasts in the study area is fragile, while there is a predominant tendency of regression of the coast line towards the inland
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
