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
Diagnostic Assessment of Property Tax in Nigeria – The Case of Kaduna State
Full text linkNigeria has experienced weak tax policies and administration, limiting the funding of essential public goods and services. Property tax has significant revenue potential for subnational governments, but remains underused due to economic, administrative, and political challenges. To uncover these challenges, a diagnostic assessment was conducted to identify gaps and weaknesses in the property tax system in Kaduna State through surveys of stakeholders’ perspectives, including fiscal and tax authorities, land authorities, judiciary and legal professionals, financial services providers including tax practitioners, valuation and technology professionals, non-government actors and civil society organizations, as well as property taxpayers including property owners, developers, and property tenants. The findings from the surveys revealed key challenges relating to property tax administration in the state, including poor billing systems, limited property identification, weak enforcement, low compliance, and lack of transparency in valuation. Therefore, reforms are needed to clarify the role of relevant agencies in the delivery of bills. It is also recommended to enhance enforcement mechanisms, expand property identification, and deploy a transparent, points-based valuation method
Diagnostic Assessment of Property Tax in Nigeria – The Case of Ekiti State
Full text linkNigeria has long faced weak tax policy design and administrative capacity, constraining its ability to mobilize domestic revenue to finance essential public goods and services. Although property tax represents a significant and stable revenue source for subnational governments, it remains largely underutilized due to persistent technical, administrative, and political challenges. In Ekiti State, these constraints have severely undermined property tax performance, with revenues estimated at only 0.002 per cent of the state’s Gross Domestic Product (GDP) between 2021 and 2023. To better understand the underlying causes of this poor performance, a diagnostic assessment was conducted to identify gaps and weaknesses in the property tax system through stakeholder surveys. The assessment captured perspectives from fiscal and tax authorities, land administration agencies, the judiciary and legal professionals, financial service providers (including tax practitioners), valuation and technology professionals, non-governmental and civil society organizations, as well as property taxpayers—namely property owners, developers, and tenants. Survey findings highlighted several systemic challenges, including weak inter-agency collaboration and limited information sharing, incomplete property identification and registries, inconsistent valuation practices, unclear or unevenly applied tax rates and exemptions, and inefficiencies in billing and collection processes. Despite these challenges, the assessment revealed substantial untapped potential for property tax revenue. A coordinated and comprehensive reform agenda aimed at addressing these institutional and administrative weaknesses could significantly enhance property tax performance and help unlock sustainable revenue for Ekiti State
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
