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
A Vulnerability Analysis of Coral Reefs in Coastal Ecotourism Areas for Conservation Management
No full textCoral reef ecosystems provide many ecological, economic, and social benefits. Despite their numerous functions, coral reefs are in a vulnerable state due to the effects of human activities. The condition of coral reefs has decreased in many parts of the world. Therefore, coral reef examinations need to be carried out continuously in order to formulate management strategies that can reduce their vulnerability over time. This study aims to analyze the vulnerability index of coral reefs, the sensitivity of coral reefs to the causes of vulnerability, and the adaptive capacity to anticipate vulnerability. The primary data are the perceptions of respondents’ who filled out a prepared questionnaire which included eight dimensions: information on the environmental conditions, fishing ports, fishing areas, coastline settlements, tourism management, tourism attractions, socio-economic conditions and population, and aquaculture. The data were analyzed using multidimensional scaling (MDS). The results of the analysis revealed that fishing ports, fishing areas, and environmental condition are high vulnerability indexes which cause damage to coral reefs. The highest coral reef vulnerability sensitivity was found to be triggered by the distance from fishing areas and the distance from fishing vessel channels. An inverse relationship between vulnerability and adaptive capacity was shown. Hence distance from fishing areas and distance from fishing vessel channels are the attributes that have low adaptive capacity

No full textThe purpose of this research are (1) to identify and analyze mangrove vegetation on the Ngantep Coast; (2) Identify associated biota in mangrove vegetation on the Coast Ngantep. The research was conducted in the Coast Ngantep area of Kabupaten Malang in april 2016. The method of measurement mangrove by using the method the combination and line transect plot with line plot 10 x 10 m2 long, in each line there are subplot with 5x5 m2 and 2x2 m2 long. The categories of sample will be discribed were trees, sapling and seedling. The result of thie researh found that the composition and the vegetation level of mangrove forest divided into IVI Sonneratia alba (tree) 128.63%, (sapling) 62.19%; Excoecaria agallocha (sapling) 63.72%; Xylocarpus granatum (sapling) 29.45%; Rhizophora mucronata (seedling) 116.21% and Nypa fruticans (seedling) 83.79%. The number of IVI discribe that Sonneratia alba very strong influence for the stability of ecosystem in mangrove forest in sute research. There were five families that make up the mangrove vegetation: Lythraceae, Rhizophoraceae, Euphorbiaceae, Meliaceae and Arecaceae. Mangrove vegetation on the Ngantep Coast dominated by the mangrove species of Sonneratia alba, with the low ecosystem show not yet stable. Fauna in mangrove vegetation Ngantep Coast become form between two groups of terrestrial and aquatic.
