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
The Use of Information and Communication Technology (ICT) and the Challenges Faced by Ugandan Smallholder Farmers. Review Article
Get PDFThe influence of ICT use on smallholder farmers in rural farming is examined in this article, as well as the obstacles that ICT use presents. The paper reviews that ICT plays a very important role in the dissemination of improved service technologies to farmers. The review stresses that ICTs are often used as an associate degree economical tool to induce non-progressive farmers to connect to extension information and to inform them adopt technology quicker. On the impacts of ICT on farmers, it is absolute that it considerably exaggerates agricultural development by serving to farmers to access relevant information through ICT and creates awareness of the market system among farmers and advert of the products and services. Likewise, the review known as some constraints by farmers within the course of the utilization the use of ICT embeds inadequate ICT facilities and personnel in rural areas, unstable Power provide in rural communities and farmers’ perception of the ICT skills. The solutions to the constraints by farmers within the usage of ICT is the event of the ICT within the reach and data of farmers, supporting farmers in capability building before the utilization of the ICT devices, and steadily provide power in rural communities
Mobile Telephony as an ICT Tool for Agricultural Information Dissemination in Developing Countries: A Review
Get PDFIn emerging nations, the use of information and communication technology has considerably benefitted the advancement of agriculture, health, rural development, and education. This technique has had a considerable impact on the way agriculture is developed in third-world countries. For information on the weather and prices, farmers now have direct access to the market, buyers, customers, and the metrological department. Information and communication technology has increased farmer incomes all over the world. It is now vital to provide access to facilities and introduce technology to rural areas where farmers lack knowledge, information, and skills regarding this technology. Several studies have also demonstrated that the adoption of information and communication technology tools in agricultural production has increased agricultural productivity. A few of the major problems and challenges that farmers encounter includes inadequate information transfer, poor agricultural practices, record reconciliation between farmers, the government, and traders, and a lack of understanding of the best farming technique
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
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
Information Communication Technology Devices for Agricultural Information Dissemination among Smallholder Farmers in Uganda (Rubanda, Mayuge Districts, and Mbarara City)
Get PDFAgriculture continues to be the main source of livelihood in developing countries and smallholder farming is the most common type of agriculture practice supporting more than 70% of the population. On the other hand, information and communication technology (ICT) is quickly growing as its helping to connect easier and faster; thus, a dire need to harness it in promoting the agricultural sector. This study investigated the Information Communication Technology Devices for Agricultural Information Dissemination among Smallholder Farmers in Uganda (Rubanda, Mayuge Districts, And Mbarara City). The study adopted a cross-sectional research design that comprised a mixed methods approach of quantitative and qualitative. The instrument for this study consisted of structured questionnaires and interviews. More so, available reports and records were explored. The questionnaire was subjected to face and content validity and reliability test. Data collected were analysed using descriptive statistics of frequency counts and percentages. Findings show that the leading types of ICT devices for agricultural information dissemination in Rubanda District, Mayuge District, and Mbarara City were mobile phones and radios. The study recommends that the most important information to farmers should always be disseminated via phone conversation, texting, and radio for broadcast agricultural-related programs in respective local language
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
