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
Effect of sedentarization on the economic, social and cultural activities of fulani agro-pastoralists in Oyo state.
No full textThe paper investigated the effect of sedentarization on socio-economic and cultural activities of Fulani agro-pastoralist in Oyo state. Random sampling technique was employed to select 171 agro-pastoralists in the state. Chi-square was used to test relationships between personalcharacteristics of respondents and their non-agricultural activities as a result of sedentarization. The result shows the mean age of respondents as 38 years and majority were male (83.9%). All the respondents were married and were polygamous with mean household size of 9 persons.The respondents had low level of education as 58.8% had no formal education. Majority (78.4%) had settled in the study area for over 11 years. Free use of land (63.2%) was common among respondents, while 60.2% had herd size of 30. Respondents were highly involved in livestock enterprise namely cattle (60.2%), while their involvement in non-agricultural activities was low. Crops like cassava, maize sorghum and vegetable were cultivated for household use except millet, and soybeans which were cultivated for household use and sales. Socio-cultural activities that changed as a result of sedentarization include their building pattern), diet status) and mode of dressing while there was no change in their marriage pattern/ceremony and early marriage). Significant relationship existed between sexes, age, length of settlement and the type of non agricultural activities the pastoralists are involved.Keywords: Sedentarization, Agro-pastoralists, Activities, Effect
EFFECT OF LAND DEGRADATION ON INCOME GENERATING ACTIVITIES OF FARMERS IN
Get PDFLand degradation in south eastern part of Nigeria is becoming widespread because population pressure is increasing, fallow land are unavailable for agricultural activities and even marginal lands are being lost to developmental projects. The problem of land degradation emanated from increase soil erosion, vegetation degradation and hydrological changes leading to loss of land productivity necessitates this study. One hundred and eighty crop and livestock farmers were sampled from a list of 1800 obtained from seven villages randomly selected from Agricultural Development Programme Zones. Instrument used in data gathering was interview schedule. Majority of the respondents are literate and have multiple income generating activities. Crop farming, collection of forest products and goat rearing were the most negatively affected income generating activities. Sex, age, educational level and household size have significant relationship with farmer’s involvement in income generating activities. Significant differences exist in farmers’ income generating activities before and after land degradation. Indigenous practices adopted in controlling land degradation do not have significant relationship with farmers’ involvement in income generating activities. Government, non-governmental organizations and community leaders should intensify efforts at educating farmers on the need for use of environmentally friendly farming system
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
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
