Un questionario per un’analisi di sostenibilità: il primo passo verso la Life Cycle Sustainability Assessment
No full textL’obiettivo principale di questo lavoro è la presentazione di un questionario, quale strumento d’indagine per la raccolta di dati primari per l’analisi delle prestazioni di sostenibilità di un prodotto edile. In particolare, tale questionario renderà più agevole la fase di raccolta dei dati finalizzati all’implementazione della Life Cycle Sustainability Assessment (LCSA) ai principali materiali utilizzati in edilizia.
Il settore edile in Sicilia riveste un ruolo rilevante, nonostante la crisi, e questo lo rende un settore strategico per uno sviluppo di tipo sostenibileThe main target of this work is the presentation of a questionnaire as a useful tool to collect primary data for a sustainability assessment of building products. The questionnaire will facilitate data collection, to implement the Life Cycle Sustainability Assessment methodology (LCSA) to the main building materials.
The building sector plays a meaningful role in Sicily, towards a sustainable development
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
Life cycle sustainability analysis of resource recovery from waste management systems in a circular economy perspective Key Findings from This Special Issue
Full text linkUnder this perspective, the Special Issue (SI) was published in this journal to motivate prominent researchers to explore the relevance of assessing—and possibly integrating—
those dimensions for the improvement and promotion of sustainable CE-based waste
management systems.
This SI was developed based upon the concern that sustainable waste management
under the CE perspective can contribute to the transition towards equitable, sustainable,
post fossil-carbon societies. It is time for CE-based
societies where responsible and sustainable manners of managing waste are implemented
and pursued. A successful transition should be, however, envisioned, designed, tested
and implemented to ensure production, distribution and consumption of value-added
waste-derived commodities that respond to the three dimensions of sustainability, or to the
seventeen United Nations sustainable development goals.
In this context, this SI attempts to highlight the importance of academic research to
assess and stimulate holistically integrated sustainability of waste recovery systems in a CE
perspective. By doing so, the SI could serve as a platform for enhancement of knowledge
on emerging methods, practical implementations, state-of-the-art analyses, findings and
lessons learned in this research content area.
Finally, as the conclusive step of the SI development, this editorial was developed to
review and build upon the seven collected papers, to highlight their main objectives and
findings and, so, their contributions to CE research
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
