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
Options for land conservation practices based on land use and land degradation in upland Luas Watershed Bengkulu Indonesia
No full textThis study is objected to determine the options for land conservation based on degraded land in upland of Luas watershed, Bengkulu, Indonesia. This work was conducted on the upland from November 2015 to February 2016. The location was geographically lying on 103020’47” - 103058’50” Latitude., and on 04021’10” - 04037’12” longitude, in Kaur District, Bengkulu Province. The total area is 55,045.23 ha where the forest covers 52,432.95 ha or 95% of the upland of Luas watershed. The spatial analysis for land degraded level was based on overlaying from attributes of some parameters such as; land cover, slope, erosion hazardous level, land productivity and management. The analysis is conducted by converting analytical geographical coordinates into Universal Transverse Mercator (UTM). The upland of the watershed is currently under environmentally pressures which around 24% in poor conditions and 23% of the area are degraded. The Limited Timber Forest areas of Air Kinal, Kaur Selatan, and the protected forest area of Bukit Raja Mendara can potentially be rehabilitated by applying concepts of social forestry with introducing agro-forestry cultivation models. All areas of agriculture cultivation in this study can be effective using land conservation tillage and management which concerning all environmental values for the sustainable productivities
Analysis of erosion hazardous level and sedimentation in Manna Watershed, Bengkulu Province Indonesia
No full textThe research purposeis to analyze erosion hazardous level and sedimentation on Manna watershed, Bengkulu Province. The research area geographically lies between 102°51′38.2″-103°10′57.8″ East., and 4°0′39.6″-4°29′38.0″ South covering 72,071.9 ha. Potential erosion yield and level were calculated by applying Universal Soil Loss Equation, and spatial analysis of the erosion was done using ArcGIS. The potential erosion in Manna watershed was classified as moderate hazardous level of 12,442,368.12tons yr−1 or similar to170.68 tons ha−1yr−1. Moderate to high level Soil erosion covered areas of 47,359.00ha, or 65.19% of Manna watershed, and high risk of potential erosion with very high sedimentation rate amounted to 248.851,1 tons yr−1. In short, land cover in Manna watershed was generally in high environmental pressures, therefore, and in future, water resources would face environmental problems
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
