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
Ukrainian Crisis: comparison and confrontation between Eastern and Western perspectives and prospects.
No full textSince the end of the Cold War, Europe has never been so peacefully consolidated. However,
its vulnerability still exists in a context of increasing globalization, where societies are facing
security threats and challenges that are growing in size and sophistication, as Ukraine
highlights. To protect freedom, security, human rights, political stability, democracy and
cultural identity, the EU developed effective tools within which research and innovation can
play a fundamental role of support to understand, identify, prevent and discourage security
threats. Horizon 2020 programme section “Secure societies: Protecting freedom and security
of Europe and Its Citizens” designed to improve border security through conflict prevention
and peace-building, will contribute to the implementation of Europe 2020 strategy. The aim
of this paper is to define the advancement degree of the functional change on EU Eastern
borders and to understand the value and the future geopolitical implications of the relations
between Ukraine, Russia, EU, and USA

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
Patrimonio, Patrimonializzazione e Potere: intersezioni , riflessioni e dinamiche socio-politiche
No full textReal estate market and foeign investment flows. Could Brexit enable redistribution?
Full text linkForeign investment in the real estate market has been growing steadily in the UK
economy for more than 20 years, to the point of creating the inverse problem of
emptying the central districts, a direct consequence of the wealth effect generated by
the overvaluation of the currency. This leads real estate developers to leave their own
space empty rather than rented, with the aim of increasing the instrumental value of
the property, giving up the progressive profitability of the asset and causing damage
to the real economy, due to the decrease in available real estate assets. While there is
a positive correlation between property prices and the current account, the long-term
effects of Brexit could lead to a loss of attractiveness of the UK as a preferred location
for real estate investments and cause a decline in foreign flows in the real estate market,
opening the door to a crisis in the sector, the resilience of which is already being tested
by the closure of several investment funds. Through the analysis of sector variables
and related geopolitical and geo-economic issues, the work constitutes an attempt to
outline the possible scenario of redistribution of foreign investment flows in the real
estate sector and the development prospects of the main European countries and
capitals potentially affected by their reallocation
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
