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
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
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
The climate change adaptation potential of integrating urban agriculture with architecture in inland South African cities
Get PDFThesis (PhD)--University of Pretoria, 2020.In response to the protracted and ineffective international action on the climate change crisis, this study critically considers the potential of building-integrated agriculture (BIA) as retrofitting strategy to improve the climate change adaptation (CCA) capacity of buildings in South African inland cities. Based on a pragmatism paradigm, the study uses a mixed method research design, to evaluate current BIA farms and their efficacy as CCA retrofitting strategies to improve the thermal performance of the local built environment.
The exploratory research is structured in three phases. During the first phase the unused and underutilised spaces of Hatfield, a rapidly changing neighbourhood in Tshwane, South Africa, are mapped and defined in terms of their latent climate change adaptation capability. Secondly, the spatial and technological characteristics of the current BIA industry is surveyed through a series of interviews and observational studies. As the final research phase, a specific BIA farm type, passively controlled non-integrated rooftop greenhouses, is assessed in terms of its reciprocal thermal impact on the built environment.
As outcome, the research findings reveal a land-use form that can contribute to the climate change adaptation response strategies of South African cities on a spatial level. Unfortunately, the design resolution and technological realisation, specifically the prevalent form currently implemented in Johannesburg and Tshwane, adversely affect both farmers and building occupants during overheated periods. As a result, the study advocates developing and testing contextually appropriate technological solutions in the BIA industry.
The study advances the climate change discourse by assessing the performance of BIA farms as constituent entities in networks of small-scaled climate change adaptation projects in resource constrained urban environments.ArchitecturePhDUnrestricte
The Hanoak House as a flexible and adaptable vernacular precedent for modern architecture
Get PDFGlobally the adverse effects of climate change necessitate the implementation of resilient systems that respond to escalating weather fluctuations and increased urban vulnerability. This requires a shift from the traditional efficiency-focused solutions, towards robust, responsive and flexible models. While novel technologies are being developed to address these needs; existing vernacular examples also present innovative solutions. The purpose of this study is to analyse vernacular solutions, in this case Korean Hanoak housing typologies, in terms their integration of flexible and adaptable spatial and technological systems to inform modern applications. As research method, the study firstly employed an unstructured observational method to document the spatial and technological elements of these vernacular precedents, followed by an intersubjective literature review of these precedents to understand the historic context. As main conclusion the study identified seven design principles to inform the development of flexible and adaptable modern architecture solutions. These include: holistic, integrative design; articulated and reciprocally layered systems; nested levels of flexible and inflexible systems; appropriate scale identification; and appropriate technology use. As contribution, this article analyses existing vernacular precedents and highlights principles that can be applied in various contexts to develop locally responsive and flexible architecture.http://www.iieta.org/Journals/IJSDPhj2022Architectur
Heat stress : adaptation measures in South African informal settlements
Get PDFDATA AVAILABILITY : The data underpinning this project are available at the following online repository: 10.25403/UPresearchdata.21747443.Globally extreme weather events are experienced most acutely in cities. While formal
settlements can respond to such events, informal settlements are often vulnerable and illprepared.
Sub-Saharan Africa is rapidly urbanising with informal settlements that require
effective climate change adaptation measures. Two climate adaptation strategies for
informal dwellings are considered for their success under 2100 Intergovernmental Panel
on Climate Change (IPCC) climate scenarios. Using existing data collected from informal
dwellings in South Africa, the findings from a digital simulation study reveal that cool roof
paints can currently lower excessive heat stress conditions by 42–63% when applied to high
thermal mass dwellings with poorly insulated lightweight corrugated sheeting roofing.
However, for the future 2100 climate scenarios this strategy only lowers excessive heat
stress conditions by 12–17%. This calls for the development of integrated multifaceted
heat stress adaptation strategies for informal settlements in Sub-Saharan Africa.The United Nations Children’s Fund (UNICEF) One Health For Change (UP-OHC) project and is part of the University of Pretoria Built Environment and Public Health Nexus project.https://journal-buildingscities.orgam2024ArchitectureSDG-11:Sustainable cities and communitie
