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
Renewable energy projects in rural China: a systemic capacity development approach
Full text linkRenewable energy can provide sustainable energy services in rural areas. However, ensuring the continued functioning of the technology in remote locations has been a major challenge. The aim of this study is to identify strategies that have been most successful in enabling access to sustainable energy services in rural areas of developing countries. This thesis draws on literature from the fields of capacity development, technology studies, and renewable energy project implementation. The strategies were identified by comparing existing frameworks with empirical data from three case studies of renewable energy projects in the Inner Mongolia Autonomous Region, China. Data for the case studies were collected via literature search, project document collection, site visits and interviews with a wide variety of stakeholders. The key findings of this thesis are that expanding energy access in developing countries will require significant capacity development efforts. Delivering energy services using decentralised renewable energy systems require the involvement of a diverse range of actors, including governments, program planners, equipment manufacturers, system designers, service networks and end-users. The most suitable delivery mechanism for sustainable energy services will vary from one location to another because of differences in the actors involved, their existing capacity and the history of their interaction. Assessing and building upon existing capacity is essential for delivering energy services in rural areas effectively. A major contribution of this thesis is the development of the “renewable energy capacity pyramid”, an analytical framework that explains how rural electrification projects can enhance local capacity in a systemic way. The framework includes tools; skills and knowledge; organisational structures; sectoral networks; and the institutional environment. This study found that the provision of sustainable energy services in rural areas of developing countries is most successful when each project contributes to the evolution of these interrelated elements over a long timeframe. The capacity pyramid can be used to guide the design and assessment of renewable energy rural electrification projects within China and in other developing countries. The framework also contributes to a deeper understanding of capacity development in other sectors, especially where infrastructure is central to the challenge of service provision
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
Monitoring and Evaluation of PV Programs in Rural Areas in the Asia-Pacific Region
Full text linkAn estimated 1 billion people living in rural areas in the Asia-Pacific region do not have
access to modern energy and the basic services it provides. Photovoltaic (PV) programs
have been implemented in many countries in the region to address this need.
International experience has shown that the continued operation of PV systems in rural
areas largely depends upon institutional factors such as program design, maintenance
and training. Therefore, monitoring and evaluation of PV programs along institutional
and technical dimensions are essential for improving the performance of existing PV
systems and future programs. This paper will discuss the monitoring and evaluation
methods used for PV programs, with a special focus on comparative work in the Asia-Pacific
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
