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
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
Attitudes of Librarians towards the use of Information and Communication Technologies in Zambia
No full textInformation and Communication Technologies (ICTs) are becoming widespread and libraries in developing countries are quickly adopting them. However, This is not matched with the requisite training and attitudes towards their use. Like in other developing countries, Libraries in Zambia are also rapidly adopting ICTs. Their application however, largely depends on the attitudes of librarians towards them. The purpose of this study was therefore to survey the attitudes of librarians towards the use of Information and Communication Technologies in Zambia. The study was intended to find out whether librarians were trained in the use of ICTs, their perceptions towards the use of ICTs, and factors contributing to their perceptions. This study also focused on how training of librarians in ICTs could influence their use. A survey method was used to collect data in tertiary and research institutions in Lusaka, Central and Copperbelt provinces of Zambia through a self-administered questionnaire. Data collected from 90 librarians were analyzed using the Statistical Package for Social Sciences (SPSS) and Microsoft Excel; and presented in the form of descriptive statistics.
The findings revealed that librarians had training in ICTs received at University or College during their formal training. The perception of librarians towards use of ICTs was also generally positive as they consented to most of the attitude items. The study revealed that older librarians were uncomfortable to learn new skills compared to younger librarians and also feared that years of routine work could be replaced instantly with the introduction of ICTs. ICTs were also so recent that most librarians over the age of 280 have not had the benefit of computer training in the course of their studies. Younger librarians also rated their computer proficiency highly than older librarians. Non-professional librarians were also not given equal opportunity to use ICTs. Also, the tasks of librarians were very different and consequently the use of ICTs was more important to one group of librarians than the other. Furthermore, ICTs were recent and recently qualified librarians are trained in ICTs. The study also revealed that librarians employed on contract were given less opportunity to use ICTs and they also worked fewer hours than those on permanent. They also had belated or insufficient training hence found ICTs harder to use. Some librarians were afraid of being replaced by librarians with relevant skills, they also feared the effect brought about by ICTs on their health. Other librarians also believed that ICTs brought uncertainty and discomfort in them with regard to their job security.
Information and Communication Technologies also brought more demand on librarians. However, the study revealed that ICTs never create additional tasks to be performed by librarians in a day. If further revealed that training was vital in influencing use of ICTs.
Management should therefore, not overlook the perceptions of librarians and their training when new technologies are being introduced as users are key in the success of the adoption and use of technologies.
I t is therefore recommended that more emphasis should be placed on changing the attitudes of librarians towards the use of ICTs. Equal opportunity of access to ICTs should also be given to all irrespective of gender, age and employment status, and attitude of librarians. To ensure successful adoption and implementation of ICTs, users of the new system are involved in the automation of the libraries. A funding policy should be put in place for training and procurement of ICT equipment and ICT should be a core component of formal library education in Zambia
