Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Essential oil composition of Daucus carota ssp. major (Pastinocello carrot) and nine different commercial varities of Daucus carota ssp. sativus fruits
No full textThe chemical composition of the essential oils obtained by hydrodistillation from the pastinocello carrot, Daucus carota ssp. major (Vis.) Arcang. (flowers and achenes), and from nine different commercial varieties of D. carota L. ssp. sativus (achenes) was investigated by GC/MS analyses. Selective breeding over centuries of a naturally occurring subspecies of the wild carrot, D. carota L. ssp. sativus, has produced the common garden vegetable with reduced bitterness, increased sweetness, and minimized woody core. On the other hand, the cultivation of the pastinocello carrot has been abandoned, even if, recently, there has been renewed interest in the development of this species, which risks genetic erosion. The cultivated carrot (D. carota ssp. sativus) and the pastinocello carrot (D. carota ssp. major) were classified as different subspecies of the same species. This close relationship between the two subspecies urged us to compare the chemical composition of their essential oils, to evaluate the differences. The main essential-oil constituents isolated from the pastinocello fruits were geranyl acetate (34.2%), α-pinene (12.9%), geraniol (6.9%), myrcene (4.7%), epi-α-bisabolol (4.5%), sabinene (3.3%), and limonene (3.0%). The fruit essential oils of the nine commercial varieties of D. carota ssp. sativus were very different from that of pastinocello, as also confirmed by multivariate statistical analyses
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
ENEA PAES: A Web Platform for Supporting Italian Municipalities in Sustainable Energy Action Plan
Get PDFThe Covenant of Mayors promotes the Sustainable Energy Action Plan (SEAP), aiming to mitigate greenhouse gas (GHG) emissions in line with the European Union’s 2030 and 2050 targets. The Covenant signatories could take enormous advantage from a digital platform that allows SEAP drafting also to no technically skilled users, like majority of them are. The Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) has developed the PAES platform in order to provide digital support to public administrations (PA) adhering to the Covenant of Mayors. The platform exploits open data and it is fed by energetic data aggregated on a municipal level. The platform offers appropriate functionalities for baseline CO2 emissions inventory (BEI) filling out and a best practice (BP) simulation tool. The latter allows to contextualize each BP and to estimate its effects in terms of the main GHG emission. The BP showing the best estimation results can then be converted into concrete adaptation actions. So, this digital system facilitates local Italian municipalities in the strategic planning and monitoring of adaptation actions taken over time
La piattaforma K-COM. Un sistema di comunicazione della conoscenza
Get PDFIl presente rapporto illustra la progettazione e l’implementazione del portale K-COM (Knowledge COMmunication) per la gestione della conoscenza. La piattaforma, sviluppata nell’ambito del progetto ES-PA (Energia e Sostenibilità per la Pubblica Amministrazione), mira ad organizzare la conoscenza in “oggetti” (OK) all’interno di specifici “percorsi” (PK) riguardanti i temi dell’efficienza energetica. Per “oggetto” di conoscenza si intende una risorsa di diversa tipologia (audio, video, testuale, ecc.) inserita all’interno di una specifica tematica e identificata da una scheda informativa (Card). Alcune delle tematiche presenti in piattaforma riguardano gli Attestati di Prestazione Energetica (APE), i Piani di Azione per l’Energia Sostenibile ed il Clima (PAESC) e tecnologie per la lotta al cambiamento climatico. Il sistema è pensato per stabilire una comunicazione bidirezionale verso un’utenza variegata ed in continua evoluzione. Esso, inoltre, prevede meccanismi di feedback e profilazione utente. In linea con gli scopi del progetto, le categorie di utenza scelte sono state i decisori delle amministrazioni pubbliche, gli stakeholder ed il personale tecnico e amministrativo impiegato sia nel settore pubblico che privato. Le classi di utenza saranno ampliate, nelle successive fasi di esercizio, aggiungendo ulteriori temi di interesse.This report describes the design and implementation of the K-COM (Knowledge COMmunication) web portal for knowledge management. The platform, developed as part of the ES-PA (Energy and Sustainability for Public Administration) project, aims to organize knowledge into "objects" (OK) within specific "pathways" (KP) regarding energy efficiency issues. A knowledge "object" means a resource of different types (audio, video, textual, etc.) placed within a specific topic and identified by an information card (Card). Energy Performance Certificates (EPC), Sustainable Energy and Climate Action Plans (SECAP) and technologies to address climate change are just some of the topics on the platform. The system is designed to establish two-way communication towards a variegated and dynamic user base. It also provides for feedback mechanisms and user profiling. In line with the aims of the project, the user categories chosen were government decision makers, stakeholders and technical and administrative staff employed in both the public and private sectors. The user classes will be expanded in subsequent phases of the exercise by adding additional topics of interest
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
