Exploring the Effect of Mobile Phone on Smallholder Farmers’ Livelihood
Full text linkThis article is based on a sequential exploratory mixed method research which carried in-depth interviews, content analysis, semi-structured participant observation, and administered a survey to 422 smallholder farmers in Machakos County in Kenya. The study was premised on combined concepts of information needs assessment (INAM), Sustainable Livelihood Framework (SLF), and ICT4D value chain analysis models to explore the effect of mobile phones on smallholder farmers’ livelihoods. The study found out that mobile phones are not used by smallholder farmers’ in the same way and therefore its effect on their livelihood is not uniform. On the one hand, mobile phone has negligible effect on subsistence smallholder farmers on-farm activities, and on the other hand, mobile phone usage has huge impact on market-oriented smallholder farming because it improves the relationships and interactions between the farmer and other rural livelihoods stakeholders
Assessing the Best Practices in Media and Communication Training
Full text linkThis article tries to assess how Media and Com–munication training in Kenya has adapted to the changes in the industry based on a mixed methods study. The article argues that universities are trying to adapt their media and communication curricula to the converged media landscape by adding ‘new media’ units that try to address the changes in the industry. They have maintained specializations (Broadcast, print, film) but none has a general programme that equips students with skills to work across media. There is a divergent view between practice and academy on the extent. This is because their perspectives on MCS education and not what is on the ground. Therefore, there is need to bridge the gap between the two by constantly engaging in team teaching, workshops, internships and co-productions
Developing Broadcasting Industry Through Glocalisation and Hybridisation
Full text linkThis article is a qualitative descriptive study that examines South Korean and East Africa Audio-visual production and distribution policies and regulations. Through analysing the results of in-depth interviews with audio-visual (broadcast) policymakers, content producers, and audiovisual business owners, this study found that South Korea reviewed regulations and policies that were protectionist in nature to more open and collaborative policies that were in tune with the digital broadcast environment. It recommended that to create successful broadcast industries, developing countries should review their broadcast policies and regulations to be in tandem with digital and media convergence environment as well as give audio-visual industry prominence by establishing ministries that deals with broadcast-related issues to promote locally, to produce content internationally, and also to source for collaboration between local and international producers
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
