Attitude of Primitive Tribal Groups towards improved Agricultural Technology,
Get PDFIndia has one of the largest concentration of tribal population in the world. Tribal population constitutes about 8 per cent of country\u27s population with agriculture as their main occupation. It is an established fact that the tribal agriculture is mostly subsistence in nature and the tribal economy is mainly based on agriculture and Minor Forest Produce. In most of the tribal areas the adoption or spread of the new technology is seen to a very limited scale. The pace and _content of new technologies being adopted by the tribals is very slow and inadequate as due to their habitation in the remote areas of hills and in the fores
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
Improvement in Livelihoods of Tribal Farmers In Rainfed Farming Systems,
Get PDFThe East Godavari district of Andhra Pradesh State is predominantly a tribal populated district with 52 per cent (1,48,920) of the total population of 2,85,848, mostly concentrated in 559 villages of agency area and 49 villages of sub plan area. The predominant tribal groups found here are Konda Reddy, Koya Doras, Konda Kammaras, Valmiki, Manne Doras and Konda Kapus. These tribes are closely attached to their lands and forests. The lands are generally rainfed uplands and their productivity is low. Dwindling forests and non-timber forest produce have also adversely affected their livelihood
Adoption of Production Practices of Paddy by Tribal Farmers
Get PDFLarge number of technologies have been evolved in the field of agriculture but are not being accepted and adopted at its fullest extent by the farmers. The gap between recommendations by the scientists and actual use by farmers is still existing. Supe et .al (1983) and Jaiswal (1985) reported a substantial technological gap in respect of use of seed rate, fertilisers and plant protection measures by farmers. Number of factors may be responsible for the existing adoption gap. The speedy adoption of improved agricultural technologies and innovations are most important for enhancing agricultural production at faster rate and hence it is a crucial aspect under innovation diffusion process
A Study on Impact of “DAESI” Programme on Input Dealers in Andhra Pradesh
Get PDFThe Public Extension service by itself is not enough to handle the multifarious demands of the farming community and is being supplemented by private extension through agribusiness companies, input dealers, NGOs, farmers\u27 organizations, etc. About 2.8 lakh agri-input dealers are operating in rural areas in the country. Though not equipped with adequate knowledge, they have become one of the important sources of farm information to the farming community. At the all India level the input dealers stand second (13.1 %) in accessibility to the farming community for providing information on modern technologies (NSSO-2003), first being the progressive farmers. Among the states the farm-households accessing information through \u27input dealers\u27 was highest in West Bengal (36%), followed by Andhra Pradesh (30%) and Gujarat (24%) (NSSO-2003
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
