Eco-Environmental Factors of Attractiveness of North Sardinia's Coastal Territory.
No full textThe present work provides an assessment of the environmental quality of the coastal arc of north Sardinia, compared with that in the Upper Tyrrhenian Sea (Sardinia, Tuscany and Liguria), in order to complement the study with an analysis of strategic assets located in the territory as a whole. The study analyses the different components of the tourist services, with particular reference to pleasure boating (ports, basic and value-added services to boats, boaters, and other professionals who are interacting with the local harbour), in order to develop a strategy to improve the supply, modifying and integrating it with additional innovative services and to manage the best marketing efforts by identifying the subjects that decide about the holiday destination. What emerged was a gap in terms of information about coastal and inland areas near the ports, of indications concerning the many activities that the sea itself offers, beyond the simple navigation, of complementarily between ports and integration with the food supply chain and with the cultural offer of the territories. Considering such results, it is all the more remarkable to note that the two provinces analysed do have environmental and cultural resources which should only be promoted in the most appropriate way in order to implement a strategy to maximise the tourist inflow, to extend the stay or the permanence of the boats, to manage the seasonal adjustment of the presence of tourists and boaters in particular
Southern European Ports and the Spatial Distribution of EDCs
No full textIn the early 1990s the birth of an EU borderless trade area triggered radical
changes in the logistic strategy of distributors and manufacturers in order to
better serve the new, enlarged, European market. The old country-based
approach has been progressively replaced by a continental one, founded on a
different network of distribution facilities. The process of hubbing and the
creation of European Distribution Centres (EDCs), led to an unprecedented
logistics restructuring. The paper aims at outlining the main reasons of this
evolution, highlighting pros and cons of this strategic choice and the impact on
the development plans of sea ports. The recent EU enlargement from 15 to 25
members is generating a new change leading to a de-concentration of the
distribution system for main manufacturers, setting up new EDCs in the
Eastern Europe. The paper focuses on the implications of this reverse trend and
investigates the role that Southern range ports can play in this further logistics
restructuring, as they represent a strategically located gateway to serve these
regions
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
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
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
