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
Investigation on underutilized plants used as daily medication, fruit source and traditional ceremonies in Bireuen regency, Aceh, Indonesia
Full text linkBireuen is a regency that constitutes 3.13 % of the total area of the Aceh province, with elevations ranging from 0 to 2637 m above sea level (asl). Although the biodiversity of this regency is expected to be high, there is limited data available on its plant species. Many of the plants are believed to be considered underutilized. Therefore, this study aimed to investigate some ethnobotanical aspects of underutilized plant species in Bireuen Regency, Aceh. The study was carried out as a survey using an open questionnaire in 17 districts, with 70 respondents selected through purposive sampling. Quantitative indices such as Relative Frequency of Citation (RFC), Use Value (UV), Informant Consensus Factor (ICF) and Pearson Correlation were performed on RFC and UV to determine the relationship between the 2 indices. A total of 40 families and 74 plant species were recorded, identified and grouped based on their use as traditional medicine (32 families and 47 species), fruit consumption (12 families and 21 species) and traditional ceremonies (15 families and 17 species). The common methods used to prepare medicine based on these local plants were crushing or boiling to treat mild symptoms and diseases. The fruit of these plants was often consumed and some plant information is scarcely available, such as buah brahim (Uvaria siamensis) and kayee kunyet (Polyalthia littoralis). The ICF value showed that the category with the highest consensus factor was traditional ceremonies (0.85), followed by consumption as fruit (0.84), and traditional medicine (0.68). This study revealed that many local plants commonly used as part of local culture had potential medicinal properties. Therefore, further investigations are recommended to validate the use of indigenous plants and preserve the knowledge
A Analisis Tempat Penampungan Sementara (TPS) Menggunakan Sistem Informasi Geografis Untuk Pengelolaan Sampah Berkelanjutan di Kota Lhokseumawe
No full textLhokseumawe City is the center of government and economy has a dense population, with a population density index of 1,082.6 people / km2. Good waste management must be done to maintain environmental health, including the management of Temporary Shelters (TPS). Waste that is disposed of carelessly creates illegal Waste Disposal Sites (LPS) that can trigger various diseases and reduce environmental aesthetics. The focus of the research is to map the location of TPS and LPS using Geographic Information System (GIS), analyze the distribution pattern of TPS and LPS using nearest neighbor analysis on image processing software, and analyze the suitability of TPS capacity with the volume of waste from the people of Lhokseumawe City. The results of the study obtained that the TPS facilities in Lhokseumawe City are 18 TPS while there are 36 illegal LPS. The distribution pattern of TPS includes a clustered pattern with a distribution index of 0.69. The distribution pattern of LPS includes a clustered pattern with a distribution index of 0.51 and the highest LPS is found in the Muara Satu District area. The results of the analysis of the suitability of TPS capacity obtained the availability of TPS in each sub-district is still lacking to accommodate waste generation, Banda Sakti sub-district still lacks 34 TPS, Muara Dua sub-district 23 TPS, Muara Satu sub-district 15 TPS, and Blang Mangat sub-district 8 TPS..
