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
Thermography Increases LCA Reliability: a Case Study of a Process for HDPE Nets
No full textAssessing sustainability of manufacturing processes through LCA tools is a common approach today, but it
suffers some limitations, mainly due to the use of standard databases. Deepening the assessment of
sustainability is, instead, a new field of interest. This paper shows how LCA can be optimized, based on the
results of a thermographic analysis supplying detailed information to a traditional LCA tool. The aim is to
test this this approach observing a real industrial case of an Italian company producing High Density
PolyEthylene (HDPE) nets for agriculture. A thermographic analysis of the critical processes helps in
assessing the in-progress eco-profile of the process under investigation. The approach is intended as an
iterative procedure to make both LCA analysis much more pertinent to the specific application and decisions
on process sustainability more adherent to real practice. The improved LCA allowed to balance the specific
energy savings intervention (recognized by the grace of thermographic analysis) by benchmarking the
potential process quality improvements with standard reference processes. These balanced design choices
and improvements can avoid useless over-dimensioning of the devices. In turn this can help to reach
sustainable quality of both products and processe
Municipal Energy plan: a pilot experience in the south of Italy
No full textAccording theKyoto Protocol,nations around theworld,including Italy,need therationalizationofenergy consumption and lower consumption of conventional energy sources to help reduce greenhouse gases emissions. Article 5 of Italian Law 10/1991, in paragraph 5, states that municipalities with more than 50 thousand inhabitants should include a specific plan about the use of renewable energy to improve its efficiency, i.e. a Municipal Energy P lan. The purpose of this paper is to present a pilot case study in the South of Italy of Municipal Energy P lan, an indispensable tool for planning the economic, social and environmental development of the territory. The Municipal Energy Planning is identified among the priority objectives of the Environmental Action Plan adopted by Local Agenda 21. The Energy P lan collects and analyzes all incoming and outgoing energy flows in the municipal area, including the energy use for various sectors (residential, agriculture, industry and handicrafts, services, transport) and for different resources (solid fuels, derived from petroleum, natural gas, electricity). The final phase of the work will be to create some future scenarios that will be implemented by the City Council to address the strategic priorities in the years

No full textDispelling 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
