Procedure di LCA semplificata per la piccola e media impresa
No full textIl progetto eLCA è mirato a realizzare e sperimentare un sito Web per promuovere l'adozione della IPP da parte delle PMI. L'impegno assunto da ENEA con questo progetto nasce dalla consapevolezza che una tale realizzazione richiede inizialmente un investimento di tipo pubblico, per assicurare la disponibilità di conoscenze e dati, ma può essere in seguito gestita con il concorso di organizzazioni pubbliche e private. L'applicazione della metodologia LCA, come strumento di supporto all'adozione della IPP nelle PMI, riveste particolare interesse, ma necessita di strumenti specifici che rispondano alle esigenze di tali aziende. In questo senso già da alcuni anni è stato avviato un percorso di sviluppo di procedure di LCA per PMI che ha portato alla realizzazione dello strumento software VerdEE (2000) e del prototipo eVerdEE (2001). Entrambi si basano su alcuni principi quali la semplificazione pragmatica degli aspetti metodologici, definiti secondo le norme ISO 14040; la predisposizione di una notevole quantità di materiale di supporto divulgativo-formativo sia metodologico-procedurale (guide, banche dati, casi studio ecc.); il mantenimento di una procedura ben strutturata e di un'interfaccia 'user-friendly' per garantire che l'utente sia in grado di svolgere studi di LCA autonomamente, con un investimento minimo di tempo e denaro
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
eVerdEE: A web-based screening life cycle assessment tool for European small and medium-sized enterprises
No full texteLCA is a European Commission financed project aimed at realising On line green tools and services for Small and Medium-sized Enterprises (SMEs). Knowledge and use of Life Cycle Assessment (LCA) by SMEs are strategic to introduce the Integrated Product Policy (IPP) in Europe, but methodology simplification is needed. LCA requires a large amount of validated general and sector specific data. Since then- availability and cost can be insuperable barriers for SMEs, pre-elaborated data/meta-data, use of standards and low cost solutions are required. Within the framework of the eLCA project an LCA software - eVerdEE - based on a simplified methodology and specialised for SMEs has been developed. eVerdEE is a web-based tool with some innovative features. Its main feature is the adaptation of ISO 14040 requirements to offer easy-to-handle functions with solid scientific bases. Complex methodological problems, such as the system boundaries definition, the data quality estimation and documentation, the choice of impact categories, are simplified according to the SMEs' needs. Predefined Goal and Scope definition and Inventory forms, a user-friendly and well structured procedure are time and cost-effective. The tool is supported by a database containing pre-elaborated environmental indicators of substances and processes for different impact categories. The impact assessment is calculated automatically by using the user's input and the database values. The results have different levels of interpretation in order to identify the life cycle critical points and the improvement options. The use of a target plot allows the direct comparison of different design alternatives
A Life Cycle Assessment Pilot Study in an Italian Dairy Company
No full textA research project to apply LCA methodology to an Italian dairy firm was recently carried out. The main project objective was to develop a simplified methodology for introducing environmental concerns based on a life cycle approach in industry decision-making. The company was selected on the basis of the economic importance of the agro-industrial branch in Emilia-Romagna region and its technological representativeness. The entire activity is carried out under the technical and scientific supervision of ENEA (Italian National Agency for New Technology, Energy and the Environment), ERVET S.p.A. (Regional Agency for Industrial Policies), the Department of Business Administration and the Department of Applied Chemistry and Material Science of Bologna University.In this paper the methodological approach and the preliminary results of the study are discussed
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
