Rhizobacteria as Biocontrol Agents of Root Rot Disease on Shallot
No full textShallot is a high-economic value commodit, but so far the supply is still lower than the demand. One of the production problem is “moler” disease of shallot (MDS) caused by Fusarium oxysporum f.sp. cepae (FOCe). The aim of this research was to study the potentiality of shallot rhizobacteria (SRB) from various soil ordo to inhibit (MDS). This research was held in the Laboratory of Biology and Soil Health and Greenhouse at UNS. This research was carried out by exploring rhizobacteria of shallot planted on Entisols, Andisols, and Vertisols. Rhizobacteria exploration results were tested for their ability to control Fusarium oxysporum f.sp.cepae (FOCe). Inhibitory ability test of SRB to FOCe was carried out in vitro and on shallot in the greenhouse. The research cused a Completely Randomized Design (CDR) with two factors. The first factor was rhizobacteria combination and the second factor was various soil ordo (Andisols, Entisols, and Vertisols). Each treatment was repeated three times. It was obtained three rhizobacteria isolates from Vertisols (B15: 70%), Andisols (B12:45,55%), and Entisols (B10:46,67%) being the highest inhibition results to FOCe. The combination of rhizobacteria B12 and B10 provided the lowest intensity

Learning Model to Improve the Motivation and Achievement in Learning
Geography of the Class of VIII A of MTs Negeri Plupuh in the Academic Year of
2011/2012
This study is directed to reveal if the STAD learning model can be used to
improve the motivation and achievement in learning Geography.The Class Action
Research is done in 4 cycles. The data are collected by the means of interview,
observation, questionnaire, and document study. The result of this study shows
that: the use of STAD learning model can improve the motivation and
achievement in learning Geography. Learning motivation improves, shown by the
following improvements: pre-activity data with the score of 59% are included in
weak criteria, Cycle I with the score of 60% in sufficient criteria, Cycle II with the
score of 76% are included in strong criteria, and Cycle III and IV with the scores
of 86% and 89% are included in very strong criteria.
Learning achievement in the minimum passing grade (KKM) of 70
improves, shown by the following improvements: Pre-activity data shows that 7
students (22%) pass the minimum passing grade, 25 students (78%) do not pass
the minimum passing grade, mean 63.88. In cycle I, 9 students (28%) pass the
minimum passing grade, 23 students (72%) do not pass the minimum passing
grade, mean 66.74, cycle II 13 students (41%) pass the minimum passing grade,
19 students (59%) do not pass the minimum passing grade, mean 69.15, cycle III
20 students (63%) pass the minimum passing grade, 12 students (37%) do not
pass the minimum passing grade, mean 71,12, and cycle IV 31 students (97%)
pass the minimum passing grade, 1 student (3%) does not pass the minimum
passing grade, mean 74.38.
The suggestion of this study, addressed to teachers, instructors,
supervisors, and headmasters, that they are suggested to use STAD learning
model in the learning process because it has been proved that this learning model
can improve the study motivation and achievement.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
