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
Post-project Sustainability Analysis Using Complex System Approach: A Case Study in Microfinance (Revolving Loan Fund Project) in Indonesia
Full text linkPoverty and other human development issues remain a large global problem requiring a solution. The long-term effectiveness of international development projects aiming to address the issues is difficult to achieve. Even for projects that are successful in their implementation phase. One important criterion of long-term project success is sustainability which can provide long-term benefits to society. Microfinance potentially provides enduring solutions for poverty alleviation by providing permanent access to microcredit for the poor, yet it also faces challenges in its sustainability. Further, the complex characteristics of international development projects and their sustainability have created the need for a comprehensive and complex approach to projects. This study involved a post-project sustainability analysis of an international development project (microfinance/revolving loan fund) using a complex systems approach. The analysis resulted in the provision of a sustainability evaluation framework for an international development project and its application in a microfinance project; understanding the sustainability of microfinance projects through a complex systems approach; and exploration of factors that can influence the sustainability of microfinance projects. This study used both qualitative and quantitative approaches with case study design in a microfinance (Revolving Loan Fund) project in Central Java Province, Indonesia. Data were collected through interviews, observation, document review, focus group discussions (FGDs) and a survey. The data collection was conducted in the province from October 2019 to December 2020. SPSS and NVivo software was used to analyse the data. The results of the analysis are as follows. First, a framework to evaluate the sustainability of an international development project is proposed. The framework’s application shows that a complex systems approach is applicable to post-project sustainability evaluation. Moreover, the case study showed that the project is sustainable. The study has implications for project sustainability and microfinance. First, the framework provides more comprehensive information about the sustainability of a project. Second, microfinance programmes can be sustainable without subsidies and can achieve financial and social goals. Second, the results revealed that some issues arose in response to the closure of the project, and actions were taken to cope with those issues. These are related to project governance, accountability, capital and profitability, competition and empowerment. The analysis also showed that the move towards a sustainable project presents characteristics of complex systems, including interconnectedness, adaptive capacity, feedback, self-organisation and emergence (IAFSE). Further, this study’s findings have implications for microfinance sustainability management and programme design. First, they demonstrate the importance of effective stakeholder management, leadership and a network-based governance system. Second, they identify the importance of including flexibility in programme design; planning by the governing body, accountability and control mechanisms after project completion; equipping the community with knowledge and skills; and recruiting the right people. Third, an exploration of factors that may influence the sustainability of microfinance projects showed that project-based microfinance (RLF) sustainability is influenced by local project characteristics, community support and project management. This implies that project implementation and its sustainability are concomitant. Further, project implementation that considers the local community and is supported by project management may play an essential role in the project’s sustainability.Thesis (Ph.D.) -- University of Adelaide, Business School, 202
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
