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
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
Automated Recognition of 3D CAD Model Objects in Dense Laser Range Point Clouds
Full text linkThere is shift in the Architectural / Engineering / Construction and Facility Management (AEC&FM) industry toward performance-driven projects. Assuring
good performance requires efficient and reliable performance control processes.
However, the current state of the AEC&FM industry is that control processes are
inefficient because they generally rely on manually intensive, inefficient, and often
inaccurate data collection techniques.
Critical performance control processes include progress tracking and dimensional
quality control. These particularly rely on the accurate and efficient collection
of the as-built three-dimensional (3D) status of project objects. However, currently available
techniques for as-built 3D data collection are extremely inefficient, and provide
partial and often inaccurate information. These limitations have a negative impact
on the quality of decisions made by project managers and consequently on project
success.
This thesis presents an innovative approach for Automated 3D Data Collection
(A3dDC). This approach takes advantage of Laser Detection and Ranging
(LADAR), 3D Computer-Aided-Design (CAD) modeling and registration technologies.
The performance of this approach is investigated with a first set of experimental
results obtained with real-life data. A second set of experiments then
analyzes the feasibility of implementing, based on the developed approach, automated
project performance control (APPC) applications such as automated project
progress tracking and automated dimensional quality control. Finally, other applications
are identified including planning for scanning and strategic scanning
Building with earth: implementation strategies, evaluation model, and mitigation of climate change
No full textArchitecture in its vernacular form arose first from the need for security and then for climate control, playing with spatial design and materials. Spatial design and materials have been relegated to a purely aesthetic movement since the arrival of fossil-fuel based air conditioning machines marked the advent of modern architecture. Awareness of the finiteness of resources and the climate crisis has led designers and builders to work towards a paradigm shift in construction, reintegrating vernacular architecture into a more virtuous way of building. In this context, earth building is of interest, with a heritage rooted in all continents and a polymorphism of techniques that can be adapted to many contexts. This research work therefore presents a proposed answer to the question `How can the environmental relevance of the use of earthen materials be assessed using a contemporary approach in a European context?' A dual approach to the question is adopted: firstly, from the perspective of earth building professionals - architects, engineers, builders, researchers or clients; and secondly, through the engineering of a structural, energy and environmental assessment model based on the tools of designers.
Earth building professionals have highlighted the importance of knowing the local regulatory framework to set appropriate performance targets and develop a project strategy involving all stakeholders, including designers, builders and certifiers. Coordination between these actors is a prerequisite for the integration of earthen materials in a construction project. Secondly, they emphasised the importance of design adapted to the specific characteristics of the material to ensure the durability of the earth components during the construction and operation of the building. In the case of a load-bearing earth structure, a number of precautionary principles must be observed, such as working in compression and load distribution. Small-scale load-bearing projects are carried out without engineers, respecting the rules of minimum slenderness, while large-scale projects are carried out with advanced modelling and strict quality control. Once regulatory and good practice conditions are met, earthen materials are used in bioclimatic or passive design strategies, or as replacements for environmentally intensive components. However, the thermal regulation, the complexity of the thermal dynamic assessment and the complexity of the environmental data make it difficult to demonstrate the environmental performance of earth construction.
The parametric assessment model was developed in response to the need identified in the interviews to assess the environmental performance of earth construction. This model, adapted to load-bearing earth construction, first assesses a sound earth structure that complies with current building codes. Once the structure has been defined, an energy assessment, calibrated on a monitored earth building, is carried out and finally integrated into a whole life cycle environmental assessment. A sensitivity analysis of the model, consisting of architectural, mechanical, structural or contextual input parameters, highlights the influencing parameters. Aspects to be considered in structural design include design strength or shear loads; in energy use, thermal mass and insulation coupling with natural ventilation; in environmental assessment, the choice of heating/cooling system or the transport of earthen materials.
The relevance of using straw-insulated earth construction in future climates was then assessed against conventional construction systems: a heavy concrete/mineral insulation system and a light wood frame filled with cellulose. While the wood/cellulose and earth/straw systems meet the short-term (2030) environmental targets, the concrete/mineral system does not. However, it is necessary to consider the carbon sequestration of bio-based materials in the wood and earth systems to achieve the 2050 net zero carbon target. Finally, by considering thermal comfort, it was possible to assess the superior performance of the earth system in mitigating thermal stress in future climates compared to the lightweight wood frame system
