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
Kaji Eksperimental Efektifitas Penyerapan Limbah Cair Industri Batik Taman Sari Yogyakarta Menggunakan Arang Aktif Mesh 80 dari Limbah Gergaji Kayu Jati
Full text linkUtilization of teak wood saw scratches can be optimized by processing it becomes active charcoal which possesses higher economic value. The purpose of this study is to obtain mesh 80 activated charcoal made from teak sawing industrial waste and to determine it’s effectiveness in adsorbing heavy metals pollutant Cd, Pb, Cr, and colouring agent in liquid waste of batik industries. The charcoal is produced at ~5000 oC retort either for 4 hours or until white colour smoke does not appear. Charcoal was activated using H2SO4 at temperature of 5000 oC for 30 minutes in a furnace. There were 2 variables in this study, i.e weight of the activated charcoal (10, 15, 20 grams) and duration of the stirring (5, 10,15 minutes). Result of the research shows that activated charcoal made from teak wood saw scratches can be used as adsorbent in the liquid waste of batik industries such as heavy metals Cd, Pb, Cr, and dark colour. The colour gradation was found to decrease from 12600 TCU to 198 TCU, Pb content decrease from 0,189 mg/l to less than 0,0093 mg/L, Cd content decrease from 0,213 mg/l to less than 0,0093 mg/L, while Cr content decrease from 2,03 mg/l to 0,4205 mg/l
Assessment of Production Rate and Quality Analysis of Essential Oil of Clove Oil Obtained from Hydro-Distillation of Clove Leaves
No full textClove is one of the leading and potential commodities of the plantation in Madigondo. Currently, the community earns the economic advantage of clove plantation only from the buds. However, other parts of the clove plant have varied potential utilization. For instance, the abundant clove leaves are a valuable and potential source of essential oil. The community considered clove leaves as plantation waste due to a lack of knowledge on further clove leaves processing. The isolation of essential oil from clove leaves can be conducted by applying hydrodistillation. In this research, the hydrodistillation of clove leaves was conducted to characterize the essential oil of clove leaves as well as to investigate the production potency of clove leaves essential oil. The research was also conducted to determine the production rate and capacity of the hydrodistillation of clove leaves. The research shows that the optimum duration of the clove leaves hydrodistillation is 90 minutes. The yield of clove leaves hydrodistillation is 5.4%. The obtained essential oil of clove leaves has to have a density of 1.019 gram/mL and a typical odor of clove oil with a bright and yellow color. Those criteria meet the SNI 06-2387-2006 for oil of clove leaves
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
Preparation of Site Plan and Landscape Design in the Development of Green and Edu Tourism in Semoyo Village, Gunung Kidul, Yogyakarta
No full textThis research seeks to develop tourism potential and reduce economic inequality in Semoyo Village, Patuk District, Gunungkidul, Yogyakarta tourism area in order to develop this area as a tourism destination. The challenge in Semoyo Tourism Village is that there is no comprehensive spatial planning and the tourism packaging is not yet appealing. The concept for the development of Semoyo Tourism Village employs a spatial planning approach and elements of Community-Based Green and Edu Tourism development, namely attraction, accessibility, amenities, and ancillary
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
