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
Uji Ketahanan Berbagai Varietas Padi (Oryza sativa L.) Terhadap Serangan Nematoda Meloidogyne spp. di Rumah Kasa

This study aim to test the resistance of rice varieties against Meloidogyne spp. This research was conducted in the screen house, Faculty of Agriculture, Universitas Sumatera Utara with a height of ± 25 meters above sea level. The study used 5 rice varieties, namely: Inpari 39, Unsoed 1, Mekongga, Ciherang, and IR 64. The results showed that there were 2 criteria for plant resistance, namely moderately susceptible and moderately resistant. Inpari 39, Unsoed 1, IR 64, and Ciherang varieties were moderately susceptible varieties, while Mekongga was moderately resistant to Meloidogyne spp.Koresy Devanan LT. 2021.

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
IMPLEMENTATION OF COUNSELING GUIDELINES IN MAN 3 MEDAN
Full text linkAbstract: This study aims to determine and analyze the problems of counseling guidance faced bystudents of MAN 3 Medan, to analyze the implementation of counseling guidance at MAN 3 Medan,to analyze the factors supporting and inhibiting counseling guidance at MAN 3 Medan,to analyzethe contributions that have resulted from the implementation of counseling guidance in MAN 3Medan. This research method uses descriptive determination method with a qualitative approach,that is, the instrument is the researcher’s own tool, data obtained from two sources, namely primaryand secondary sources. With data collection techniques through observation, interviews anddocumentation, while the data analysis technique is done by data reduction (data collection), datapresentation, and conclusions. The data validity technique is carried out with credibility, transferability,dependability and confirmability. The findings in this study, are as follows: First, the problemsfaced by students at MAN 3 Medan are not yet having the awareness to study seriously, moststudents at MAN 3 Medan have not carried out worship activities seriously, sometimes studentsshow attitude that is not polite to the teacher, shows the behavior that is generally experienced bystudents in general such as ditching, teasing friends and others and not doing homework. Secondly,the implementation of guidance and counseling at MAN 3 Medan is compiling a work programinvolving all council teachers, making work formulas related to guidance and counselingservices, mapping service areas and prioritizing in the religious field which becomes guidance andcounseling services. Third, the supporting factors for guidance and counseling services at MAN 3Medan are the existence of data instrument applications, data sets and case of conferences.Key Word: Implementation, Counseling Guidelines, Madrasah Aliyah Neger
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
