Diversity of the Wasp (Hymenoptera: Vespidae) in Andalas University, Limau Manis, Padang
Get PDFSpecies diversity of the wasps (Vespidae: Hymenoptera) in Andalas University, Padang, Indonesia is studied. The sampling was undertaken in 6 different site around Andalas University under different circumstances, such as forest, buildings, bush, cafeteria, campground, and around basketball field. The wasps were collected by insect net, bait trap, and malaise trap. As result, there have been 16 species from 11genera of 4 sub-family collected and examined. The Eumeninae was most sub-family found in study sites with 6 genera and 6 individuals. The Shannon-Wiener index of the wasps was 0,8538, suggesting that the wasps is averagely diverse. Meanwhile, the evenness index is 1,6613 which demotes the stable evenness among location
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
The polymorphism of vespid wasps (Hymenoptera: Vespidae) from Indonesia with morphology-based cladistic
Get PDFWasps in the family of Vespidae often have a yellowish black color with white or brown markings, but some species have variations in their markings and coloring. There is limited information available about the distribution of these marking patterns within the Vespidae Family. To clarify their taxonomic status, this study aims to examine the marking patterns of Vespid wasps that are widely distributed in the Indonesian Archipelago and to explore correlations with their biogeographical distribution patterns. In this study, specimens from three different locations (Bandung, Sumedang, and Purworejo) and specimens from the Museum Zoologicum Bogoriense (MZB) were examined. A total of 31 individuals from five different species were analyzed based on their morphological features. The data collected was coded and analyzed using cladistic methods, and the results were used to create cladogram trees for each of the five species i.e., Phimenes flavopictus, Polistes stigma, Apodynerus troglodytes, Vespa affinis, and Vespa velutina, showing their biogeographical distribution. The cladistic analysis in this study showed the relationships between the different species based on their morphological characteristics. The arrangements of the clades were determined using the Euclidean method in R studio. The results showed that P. flavopictus has two clades based on the marking patterns on their thorax and abdomen, while the other species i.e., Po. stigma, V. affinis, V. velutina, and A. troglodytes have three clades based on their coloring and marking patterns on all segments. The distribution of the Vespidae species appears to be scattered, with their patterns randomly distributed among locations
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
