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
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
DEVELOPMENT OF TRADITIONAL MARKET LOCATION IN TASIKMALAYA CITY
No full textThe economic force in Tasikmalaya City is dominated by trading and processing indus-tries through trade, hotel and restaurant sector. To compensate the increase of those economic sector, the quality and quantity of traditional markets necessary to be more improved. This study aims to analyze the direction of development of traditional mar-ket location in Tasikmalaya City. This research uses descriptive analysis method. The data used are primary and secondary data collected through observation, field survey, interview, and literature study. Population and sample in this research is community around market by using Random Sampling method. Result of research indicate that development of location of Traditional Market in Tasikmalaya City is in accordance with Spatial Plan of Area (RTRW) Tasikmalaya City. The form of market development is to improve the quality of market facilities in order to compete with the super market.</jats:p

EFFECT OF GAMMA IRRADIATION ON MICROBIAL CELLULOSE MEMBRANE FOR APPLICATION IN GUIDED BONE REGENERATION (GBR)
Full text linkThe synthesis and effect of gamma irradiation on characteristics of microbial cellulose membrane have been evaluated. Microbialcellulose gel (nata de coco) was produce using bacteria Acetobacter xylinum incubated in bacterial growth medium containing coconut water as a micro nutrient source. Microbial cellulose membrane was prepared using mould compression at 120°C for 5 minutes. The membranes were irradiated using gamma rays with doses of 25 and 50 kGy respectively at dose rate of 10 kGy/h. Several parameters such as water absorption, surface morphology, thermal and mechanical properties of un- irradiatedand irradiated membranes were analyzed. The results showed that optimum production of microbial cellulose by A. Xylinum is 10 to 12 days at incubation temperature of 30°C and pH 4. Chemically treatments of MC membrane by NaOH and NaOCl solution were effective to remove the bacteria contaminant, bacterialcells embedded in the polymer net and endotoxin which occurred during cellulose production as well as produced membrane with more white colour. Water absorptionproperties of MC membranes showed maximum value at immersion temperature of 25°C, 37°C and 50°C were 110, 137 and 140 %, respectively. Water absorption of MC membrane decreases by increasing irradiation dose. Microscopic photograph of MC membrane showed that the membrane was consisted of interconnected nano to micro porous structures with diameter ranging from 0.05 to 0.5 μm. Thermal properties of MC showed that decomposition temperature of un-irradiated and irradiated MC membrane at dose of 25 and 50 kGy were 328°C, 328°C and 295°C, respectively. Tensile strength of un-irradiated MC membrane in dry state was 102 MPa. Irradiation at 25 and 50 kGy reduced tensile strength to become 85 and 51 MPa respectively. The decrease of thermal property and mechanical strength of MC membrane by irradiation is due to decomposition of polymeric cellulose to the lower molecular weight. This degradation hopefully improve biodegradation and resorptionof MC membrane in tissue cell
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
