REVIEW ON ADOPTION AND IMPACT OF IMPROVED AGRICULTURAL TECHNOLOGIES ON FARM INCOME IN ETHIOPIA
Get PDFThe importance of agricultural technology in enhancing production and productivity can be realized when yield increasing technologies are widely been used and diffused in the community. Based on this logic, this study examines the adoption and impact of improved agricultural technologies on farmers’ income in Ethiopia. One of how farm productivity can be increased is through the introduction and dissemination of improved agricultural technologies to farmers. The objective of this review was to assess the factors affecting the adoption and impact of improved agricultural technologies. Various socio-economic factors, institutional and the characteristics of the farmers were those factors affecting the adoption and intensity of agricultural new technologies. The adoption of livestock technologies was highly influenced by location factors as well as agro-ecological factors
REVIEW ON MAJOR STORAGE INSECT PESTS OF CEREALS AND PULSES
Get PDFInsect pests are the most successful and diverse groups of animals on earth and are closely related to our lives and affect the welfare of humans in diverse ways. A vast number of pest species are related to stored commodities. From this pest species, storage insect pests are a major threat to grain storage and other stored products and they cause direct and indirect losses of grain on the storage. Cereals and pulses are attacked in stores by different insect pests and other storage pests. The three orders of insect Coleoptera, Lepidoptera, and Psocoptera contain species that are major pests on stored products. The two major groups Coleoptera and Lepidoptera insects harbor the most economically important post-harvest insect pests. Some of the storage insect pests which attack storage grains are rice weevil, maize weevil, lesser grain borer, granary weevil, Angoumois grain moth, khapra beetle, Indian meal moth, red flour beetle, and pulse beetles. Callosobruchus chinensis, Callosobruchus maculatus, and Callosobruchus analis are the three commonly known pulse beetle species in stored pulses. Hence the objective of this paper is to review the major insect pests of stored grains and their management methods. Insect infestation occurs in stored grains and grain products to a variable extent depending upon the storage conditions in developing countries. Under farmers’ storage grain losses are further aggravated by poor post-harvest handling, inefficient storage facilities, and inadequate pest management systems. The stored grain pests infest grains during storage to fulfill their food and shelter requirements as a result they cause quantitative and qualitative losses. Globally, the quantitative losses of stored grain vary from developed countries to undeveloped countries. To reduce the losses management of storage insect pests by using physical, biological, botanical, chemical, host plant resistance, and integrated pest management methods are essential for the control of stored product insect pests
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
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
