The saplings vegetation and environmental factors in Malempo Hamlet of Mallawa Resort, Bantimurung Bulusaraung National Park
Get PDFThis study aimed to determine the composition and structure of sapling vegetation and the relationship of environmental factors with the structure of the vegetation in Malempo Hamlet of Mallawa Resort, Bantimurung Bulusaraung National Park, Maros Regency, which is in three regions of direction, namely South, North, and West. Laying transects were conducted randomly in each regional direction with 5 replications. Each transect was 100 × 5 meters in size, for the tree saplings, in wich they were provided with 5 × 5 meters for 10 plots alternatingly placed. Data collection of vegetation was conducted in the plot by counting the number of each species of tree saplings and determine the canopy space-filling. The composition of sapling vegetation was found 39 species from 28 families. The species of sapling tree with the highest structure of sapling vegetation in the study area based on density, frequency, dominance, and IVI is Celtis philippensis, Ardisia elliptica, Leea indica, Saurauia nudiflora, and Phytocrene macrophylla and the lowest are Cordyline fruticosa, Caryota mitis, Calamus asperrimus, and Arenga pinnata. The canopy, altitude, soil percentage without vegetation, and slope declivity have a relationship with the structure of sapling vegetation

No full textThis study aims to determine the effect of Trichoderma sp., And Streptomyces sp., On the production of garlic plants. The research objective was to obtain a combination of biological fertilizers, which are suitable for the cultivation of local Indonesian garlic plants. The study was started by making a suspension by taking the inoculant Trichoderma sp., And Streptomyces sp., Using ose, then put it in a liquid medium and incubated for 5 days. Inoculation of Trichoderma sp., And Streptomyces sp., was done by pouring it into the planting hole area of 5 mL each of the garlic plants according to the treatment consisting of control (without suspension); giving suspension of Trichoderma sp .; Suspense Streptomyces sp .; and Trichoderma sp. + Streptomyces sp. Data were analyzed using the F test, treatments that had a real effect were further tested with the Least Significant Difference Test at the 5% level. The results showed that the treatment significantly affected plant height, dry tuber weight, and tuber diameter. The highest average for all observation parameters was found in the fungus Trichoderma sp. + Streptomyces sp., While the lowest average was in the treatment without the fungal suspension for all parameters of the observation
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
