Karakterisasi Fisik dan Kimia Slag Feronikel Kecamatan Pomalaa Sulawesi Tenggara
Full text linkFerronickel slag is solid waste produced from the ferronickel treatment process. This study aims to determine the physical characteristics of ferronickel slag, determine the chemical characteristics of ferronickel slag and determine the potential leaching of pollutants from the ferronickel slag in Pomalaa District. This study uses TCLP (Toxicity Characteristic Leaching Procedure) analysis to determine the leaching potential, XRD (X-Ray Diffractions) and SEM (Scanning Electron Microscope) to determine the mineral composition. Data of particle size and density of ferronickel slag were processed using Microsoft Excel. The results of XRD (X-Ray Diffractions) and SEM (Scanning Electron Microscope) analysis showed a diverse composition of ferronickel slag minerals, consisting of oxygen (O), magnesium (Mg), aluminum (Al), silica, calcium (Ca), chromium (Cr), iron (Fe), nickel (Ni), manganese (Mn) and sulfur (S). The density of ferronickel slag ranges from 3.34 g/ml - 3.53 g/ml and the particle size of ferronickel slag varies with size variations of 2 mm, 1.18 mm, 0.6 mm, 0.3 mm, 0.21 mm, 0.106 mm and 0.075 mm. TCLP analysis shows the leaching potential in nickel slag, the element boron (B) has a leaching potential of 1.10 mg/l, mercury (Hg) with a leaching potential o
The Effect of Clove Agricultural Products on Family Welfare Level in Bontobangun Village, Bulukumba Regency
Full text linkThis quantitative descriptive study aims to determine how much influence clove agricultural products have on the level of family welfare in Bontobangun Village, Rilau Ale District, Bulukumba Regency. The independent variable in this study is the agricultural yield of cloves, while the dependent variable is the level of family welfare. The population in this study was all heads of families in Bontobangun Village, Bulukumba Regency, while the sample of this study was 89 households, a sampling technique using proportional random sampling. This study uses data collection techniques through observation, interviews, distribution of questionnaire sheets and documentation. Furthermore, the data is processed using SPSS version 22 and then presented as a table with an explanation. The results showed that the clove farmers’ results significant influenced the family welfare level in Bontobangun Village, Bulukumba Regency. The largest number of clove farmer family members is 46.0 percent who have 3-4 dependents and the lowest number of family members is 10.1 percent who have 7 to 8 dependents. Most clove farming families in Bontobangun Village, Bulukumba Regency, have reached the third-class prosperous family stage. Compulsory needs of family members such as food, clothing, education, and health, family members are dependents
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
