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
BIM Workflow for Mechanical Ventilation Design : Object-Based Modeling with Autodesk Revit®
Get PDFThis study is conducted for the Belgian engineering firm CENERGIE, whose main business activities are within the fields of building systems and sustainable buildings. The company wants to change their current design workflows to adapt the use of Building Information Modeling (BIM) with Autodesk Revit
The research focused on the development of a BIM workflow where no models are exchanged between building partners. The aim of this study was to develop such a Revit BIM workflow for the design of mechanical and hybrid ventilation systems in non-residential buildings.
Two sets of process maps were created to visualize the current and new workflow. A practical workflow is developed by examining and testing different modeling methods in the software.
Besides two Revit templates and several custom-made elements, additional tools were developed with Autodesk Dynamo®, the visual programming add-in for Revit. Customization was necessary because some built-in Revit modeling methods follow North-American design habits and standards.
Revit was successfully customized by using the earlier described methods. The steep learning curve implies that an adequate learning process and/or collaboration with specialized BIM companies will be necessary. Further research should incorporate the implementation of BIM in other CENERGIE business domains such as electricity, cooling systems, etc. Strategies for future BIM collaboration should be investigated as well
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
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
Compliance checking for construction project data with linked data
Get PDFDissertação de mestrado em European Master in Building Information ModellingO sector da construção tem assistido a um aumento da digitalização nos últimos anos, levando à
produção de quantidades cada vez maiores de dados. Estes dados estão frequentemente isolados em
sistemas e formatos de ficheiros específicos, o que dificulta a sua ligação numa representação holística
de um bem construído. A investigação existente sugere que esta lacuna entre silos díspares pode ser
colmatada utilizando Semantic Web Technologies (SWT). A aplicação das SWT resulta numa
representação formal e explícita do conhecimento, tornando possível assegurar a verificação da
conformidade dos dados do projeto de construção provenientes de diferentes fontes. Embora promissora,
a escalabilidade da aplicação das SWT no ambiente construído foi prejudicada pela falta de diretrizes
de modelação claras. Tais diretrizes foram recentemente introduzidas no mercado europeu sob a forma
de uma norma, a EN 17632-1:2022: Building Information Modelling (BIM) - Semantic Modelling and
Linking (SML), que prescreve um modelo de informação de nível superior e um conjunto de padrões de
modelação da informação. Considerando que o modelo e formato de informação Industry Foundation
Classes (IFC) é atualmente o padrão de intercâmbio mais utilizado para dados BIM, esta dissertação irá
analisar e apresentar os meios de expressar tanto o esquema IFC como os conjuntos de dados IFC de
acordo com as diretrizes especificadas na norma EN 17632. Para a primeira contribuição, o modelo de
informação de nível superior SML é alargado com conceitos do esquema IFC. Em segundo lugar, os
conjuntos de dados IFC convencionais são convertidos num gráfico de dados ligados aplicando a versão
baseada em SML do esquema IFC, bem como os padrões de modelação da informação SML. Numa
incursão no final da investigação, são exploradas as possibilidades de verificação da conformidade dos
conjuntos de dados IFC convertidos, primeiro em teoria e depois na aplicação prática num contexto mais
vasto do processo de licenciamento digital de edifícios.The construction industry has seen an increase in digitalisation in recent years, leading to production of
ever larger amounts of data. This data is often siloed in specific systems and file formats, making it hard
to connect it in a holistic representation of a built asset. Existing research suggests that this gap between
disparate silos could be bridged using Semantic Web Technologies (SWT). Application of SWT results
in a formal and explicit knowledge representation, making it possible to ensure compliance checking of
construction project data coming from different sources. While promising, scalability of SWT
application in the built environment was hindered by the lack of clear modelling guidelines. Such
guidelines were recently introduced to the European market in the form of a standard, EN 17632-1:2022:
Building Information Modelling (BIM) – Semantic Modelling and Linking (SML), prescribing a Top
Level Information Model and a set of information modelling patterns. Considering that the Industry
Foundation Classes (IFC) information model and format is currently the most used exchange standard
for BIM data, this dissertation will analyse and present the means of expressing both the IFC schema as
well as IFC datasets according to the guidelines specified in the EN 17632 standard. For the first
contribution, the SML Top Level Information Model is extended with concepts from the IFC schema.
Secondly, conventional IFC datasets are converted to a Linked Data graph applying the SML-based
version of the IFC schema as well as the SML information modelling patterns. In an expedition at the
end of the research, the possibilities of compliance checking over the converted IFC datasets are
explored, first in theory and then in practical application in a wider context of digital building permitting

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
