No full textThe sustainable lightness of environment sociology applied to hotels retrofit
No full textThe sociological approach to the issue of environmental renovation (or
green retrofit) of hotels within the S.O.L.E.H. project interacts with other disciplines, providing operators in the construction chain with tools for evaluating costs, materials and retrofit practices. Specifically, it aims to offer information at three levels of analysis, according to an already tested scheme for energy and water issues [Osti, 2019; 2020]. A rigid hierarchical vision of disciplines is abandoned, in favour of a more flexible and interdisciplinary one. The paper is composed of two parts. In the first (longer one), the analysis scheme will be briefly illustrated and it will be exemplified with the specific case of retrofit, seeking analytical and practical connections with the S.O.L.E.H. research. In the second (shorter one), some considerations will be drawn on the usefulness of an integrated approach to the study of socio-environmental phenomena
Sustainable tourism must be not an oxymoron
No full textFor some time, in fact, tourism has been perceived as a controversial source of income: while no one questions its relevant contribution to the growth of cities and the whole areas, social consequences and environmental impacts have been progressively emphasized as well as its lack of coordination among the economic agents, the strong competition and the reluctance to be involved in homogeneous and shared development strategies. After years of steady growth, tourism has become an economic sector with powerful dynamics, but evidencing substantially ungovernable, unpredictable trends and mostly heavy environmental impacts.
What seems to be lacking in many touristic contexts, what seems to have not yet been assumed, especially as regards tourism, is therefore a general awareness of the institutions and the necessary political willingness to drive actually and effectively sustainable development policies. To achieve this aim, it is crucial to push the political debate beyond the rhetoric of sustainability, which is often embedded in the communication, and rather affirm – as some authors have argued – an ‘institutional culture of sustainability’ that must permeate the decision-making process and all the administrative actions, making sustainability a practiced subject and not a fetish from time to time used to disguise traditional interventions into innovative and agreeable shapes
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
Up-one: Problems issuing from upward extensions of 1950-1900 residential buildings
No full textThough presenting typological and construction-related features different from other European countries, Italian residential buildings as a whole fail to meet the performances required by the European Union before the 2050 deadline. Among the hypotheses meant to upgrade residential buildings, adding floors is regarded as capable of meeting the demand for new lodgings without any further soil consumption as well as of being the driving force leading to the overall upgrading of the building. The research has been aimed at focusing on the problems arising from upward extensions within the Italian seismic context, by means of digital environment surveys, defining intervention guidelines that can be applied to adding floors to 1950-2000 buildings
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
