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
Advanced technology, quality and natural materials efficiency in the Mediterranean Climate
No full textIn the current building experience of the very technologically advanced part of the
planet, concept of Sustainability, has brought to more suitable solutions based on LCA managing
models, from material and component dimension to the accomplished built object. Nowadays,
buildings and dwellings have become dynamic and elaborate organisms. We are leaving behind
ourselves the Modern idea as Architecture as an energetic machine to move towards new
paradigms, new models based on local and energetic efficiency, innovation, costs attention and
resources utilization that might improve people life quality, even in the social dwelling size. To
achieve our purpose, we have taken environmental standards as project assumption in order to
get closer in the interactions between building as a complex system and as ecosystem. We can
apply the same sustainability assumptions in common practice and fast building-up procedures,
combining vary types of durability, reversibility, reliability even with self-construction building
procedure. As result of this way of thinking, the trial project, of a 35 sqm building module, starts.
Moreover, in this study, takes place the electrochromic (EC) glass experimentation, shifted from
continental to the mild Mediterranean climate. Studies started up in 2008 by a university and
professional research team and have been focus on compatibility condition of EC selective glass
with local materials production, answering to precise economical and environmental
requirements in a more cost/benefit awaked vision for social dwelling target. Local materials
supply, production quality, knowledge of the habitat and of the local building techniques as
brought to privilege poor materials as straw, wood, cork and wool. With these basis, the module
can fulfill different demands and functions, depending on the proper case, from the complex
building type can be suitable as social dwelling module as well. The aim of this abstract is to
show the development of the research project lead by Cagliari University DICAAR, merging the
results of the use of EC glass in mild climate, with high quality performance solutions for builder
company and local producers in order to test these solutions in vary of fields
ASSESSMENT AND COMPARISON AMONG PREDICTION METHODS FOR THE LOW FREQUENCY NOISE PRODUCED BY WIND TURBINES: APPLICATION TO A CASE STUDY
No full textThe present energy scenario leads to an acceleration in the development of the exploitation of renewable sources. Latest regulations impose higher and higher percentage shares of energy from renewable sources. The current technological advancement stresses the wind energy as an energy source endowed of a special reliability. The technology to take advantage of such a source is based on large size wind turbines, with a rated power of about 3 MW.
Among the main environmental problems that have to be faced in planning a new wind farm, the acoustic impact stands out. It consists of noise engendered by wind turbines with a special effect of noise emitted at the low frequency spectrum. Recently Denmark has produced a new regulation which calls for specific procedures for the assessment of noise at low frequencies.
Purpose of the present work is to take stock of the procedures currently employed in the predictive study of the low frequency noise produced by wind turbines. The analysis was carried out by applying the expounded procedures to a real case situated in Sardinia. It concerns a wind farm formed with 21 large size turbines, where a comparison between the results obtained by applying the procedures of ISO 9613 and those provided for by the Danish regulation is shown
