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
Insights into the Urban Building Energy Modelling (UBEM) approaches to propose a suitable UBEM strategy for Pakistan
No full textOver the past few decades, the world has seen a major population movement to metropolitan regions. About two-thirds of the world's total primary energy consumption is used in urban regions, with buildings making up a large portion, approximately 40%. A key component of creating sustainable cities is the accurate assessment of building energy use and corresponding CO2 emissions. Urban Building Energy Modelling (UBEM) has gained immense popularity recently; however, the existing state-of-the-art methodologies and tools for estimating urban-scale energy usage do not best comply with different environments. While well-structured UBEM models exist for the West, they still need to be devised in the context of Global South countries. This article proposes a bottom-up UBEM methodology for urban energy use modeling (UEUM) in the case of Pakistan. An extensive literature review was conducted to facilitate the review and assessment process, enabling the identification of various methods and approaches utilized in urban energy use modeling. Subsequently, the results of this review process were analyzed, and the challenges associated with implementing UBEM in Pakistan were elucidated. Based on this analysis, the most viable methodology and approach for UBEM in the Pakistani context is proposed. Therefore, this research provides guidance to planners, practitioners, and energy policymakers as they select the best strategies to create and carry out comprehensive sustainable building energy planning and analysis projects in Pakistan and other countries of the Global South.

Urban transformation via sustainable building stock and transportation
No full textThe imperative sustainable development goals of sustainable cities and transport have necessitated urban transformations. Buildings and transportation are pivotal elements shaping the morphology and structure of urban areas, yet they pose challenges and environmental concerns, particularly in terms of energy consumption and associated CO2 emissions. Addressing these issues and mitigating their impacts is crucial for enhancing sustainability and livability. This study focuses on Lahore as a case study, where rapid population growth, driven mainly by urbanization, has led to increased energy consumption and CO2 emissions, endangering the area's sustainability and livability. The city's environment is severely polluted, with an air quality index reaching 170, making it unsustainable for living. The research assesses the energy consumption and CO2 emissions of residential building stock and associated transport along the Bus Rapid Transit (BRT) corridor Lahore, Pakistan. Calculations include operational energy use through utility bills, and CO2 emissions using the IPCC Tier 1 methodology. A comprehensive database is established, linking energy consumption, CO2 emissions, and associated characteristics. Causal relationships between these factors are identified through multinomial regression, and potential energy efficiency improvements in residential building stock and transport are outlined. The findings aim to guide policymakers, architects, and urban planners in developing effective strategies to promote energy efficiency and reduce CO2 emissions in Lahore's residential buildings. Ultimately, the study contributes to broader objectives of sustainable urban development and the transition to a low-carbon future in Lahore, Pakistan. The findings of this study can be considered when following a similar approach in other areas, cities of Lahore also south east Asian cities
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
