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
Institutional preparedness to bus tendering in the context of a fragmented liberalized market : case study of Harare, Zimbabwe
Get PDFAbstract: While competitive tendering in urban public transport has been widely applied in the developed world, in many developing countries particularly Africa, this has not been the case. In Zimbabwe, competitive tendering was identified in 2012 as a tool to address the urban transport challenges emanating from a deregulated urban public transport market. To date, the tendering option has not been implemented. This paper examines the institutional preparedness to bus route tendering in Harare, the capital of Zimbabwe. A mixed-methods research paradigm was used to obtain data and information from three relevant transport stakeholder clusters comprising public, private and academia sectors. The findings of the study have shown that the key stakeholders have a clear understanding of what competitive tendering entails, but implementation is hindered inter alia by lack of infrastructure and support systems, lack of commitment to policy implementation and a reluctance to interfere with the status quo, which generates revenue for the economy through both legal and illegal means. The study is of value to other developing countries, particularly Africa, which may draw lessons from the Zimbabwe experiences. The study recommended the need for a detailed diagnostic study to analyse the deep rooted political and economic factors or pressures that impede a movement from the status quo
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
An analysis on institutional preparedness to bus route tendering in the context of a fragmented liberalized market: case study of Harare, Zimbabwe
Get PDFIn many cities of the developed world, the previously public owned and subsidized bus operators which provided services with minimal exposure to competition have been deregulated. Literature suggests that deregulation especially uncontrolled deregulation has resulted in an unprecedented proliferation of minibus operators, both registered and unregistered. The oversupply of vehicles inevitably leads to a reduction in round trips and reduced profits to operators. In order for operators to remain afloat in business, their drivers have developed dangerous driving behaviors typified by tailgating, picking up and dropping off passengers at undesignated sites, establishing and operating from incidental bus termini (along major roads). This behaviour is both a road capacity and safety concern. In 2012, the Government of Zimbabwe published their first National Transport Policy, which identified route tendering as one option among others, to address some of the operational challenges emanating from a deregulated urban public transport market. The objective of this paper is to interrogate whether the intention to implement bus route tendering augurs well with awareness of what route tendering entails. The following questions will be addressed: What are the views of stakeholders on competitive tendering? What benefits can accrue? What pre-conditions are necessary for the successful implementation of route tendering? Is the prevailing urban public transport institutional framework conducive and prepared for route tendering? These are pertinent questions as the country has no experience of route tendering and there are very few examples in Africa to learn from.Institute of Transport and Logistics Studies.

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
