SUITABILITY ASSESSMENT OF SOLID WASTE DISPOSAL SITES USING SOME PHYSICO-CHEMICAL AND GEO-MORPHOLOGICAL PROPERTIES OF SOILS
No full textAbstract: The soils of six locations (Rumuokoro, Eastern by-pass, Oyigbo, Bundu, Yenagoa and Bonny) indiscrimately used for disposal of wastes were evaluated for suitability classification using some physico-chemical and geo-morphological properties of the soils. The soils showed remarkable physico-chemical variability between the locations and also within the soil horizons. Yenagoa, Bonny and Bundu sites were most limited for use in landfilling of wastes and are more prone to both surface and ground water pollution due to their porosity, infiltration rate, pH, flooding, drainage and textural limitations. Rumuokoro site which was most suitable for landfilling of wastes was limited by pH, while Eastern by-pass site was limited by both the texture and porosity. This assessment shows that, no location possessed all the characteristics of waste landfilling. However, when a comparative study of the suitability of soils for waste landfilling was rated, the locations showed variable suitability in the following order: Rumuokoro > Eastern Bypass > Oyigbo > Bundu > Bonny > Yenagoa.

VERTICAL AND LATERAL DISTRIBUTION OF HEAVY METALS IN SOILS AFFECTED BY INDUSTRIAL AND MUNICIPAL WASTES IN PORT HARCOURT, NIGERIA
No full textAbstract: The distribution of some selected heavy metals (Lead, Mercury, Cadmium, Nickel, Chromium, and Iron) of five undisturbed soil profiles in Port Harcourt Metropolis affected by industrial and municipal wastes was assessed vertically and laterally, to ascertain the nature and extent of contamination, mobility particularly with respect to distance from the impact point, depth in the soil profile, and chemical form of metal in the soil. It was found that the concentration of the metals in the top-soil (0-5cm) at each site within impact point was very high. However, levels of these metals decreased with distance, with all metals reaching background levels at 100m away which show little relation to the metal loading at the surface horizon. Samples taken deeper in the profiles (30-60cm) nearly devoid of organic matter did not show elevated metal levels compared with the sites 100m away from the source. High concentration of heavy metals at the impact points of the study area could cause adverse effects on plant quality and yield, and also on human health.

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
