Content of sea grapes (Caulerpa racemose) which grow in the waters of The Button Strait and The Tiworo Strait
No full textSea grapes (Caulerpa racemosa) is a variety of green algae grown in coastal areas with bioactive compounds that have been used by humans as antitumors, antivirals, and antimicrobials. The coastal regions of Lohia district of Muna, including part of Buton Strait, and the western part of Muna district, specifically in the North Tiworo District of Muna West district, which is part of Tiworo Strait, cultivate sea wine. The purpose of this research is to identify the compounds contained in the sea wine grown in the waters of Buton Strait in Muna district, Lohía district, and Tiworo Strait in Muna West District of Tiworo North district. The methods used in this study are observation and determination of the sample take point, sampling, sample preparation, and identification of sample compounds using a spectroscopic photometer. It was found that the samples from the Buton Strait contained saponins, alkaloids, and tannins, with a water content of 15.13%, an ash content of 26.37%, a protein content of 5.24%, a fat content of 0.16%, and carbohydrates making up 53.10%. The samples from the Tiworo Strait, on the other hand, contained saponins, alkaloids, and tannins, with a water content of 15.35%, an ash content of 22.9%, a protein content of 5.20%, a fat content of 0.14%, and carbohydrates making up 56.62%
Inventory of damage to coral reefs ecosystem in waters of Bungkutoko Island, Kendari City and Barrang Lompo Island, Makassar City
No full textCoastal areas and sea have the potential biological resources large enough, because supported by three main ecosystem the ecosystem mangrove, seagrass beds and coral reefs. To maintain the existence of the ecosystem, control in coastal areas need to conducted one of them is inventory damage ecosystem especially ecosystem coral reefs. On the island of Bungkutoko lack or information on the coral reefs ecosystem is the island Barrang Lompo in addition the information and data on the ecosystem. The purpose of this research is to get data teachers’ marital status and a condition of damage the ecosystem to coral reefs as a second the island. The research results obtained, a covering of coral reef island Bungkutoko depth 5m and 10m namely 36,47% and 41,67% category ‘being’. The island Barrang Lompo station 1 the depth of 5m and 10m namely 38,67% and 42,53% category ‘being’, station 2 covering 23,27% category ‘broken’. To scattery if coral reefs Bungkutoko island 231.31 ha, the Barrang Lompo island 127.47 ha. The level of damage/index mortalities on the island of Bungkutoko depth 5m and 10m namely 0,5593% and 0,6201% category ‘being’. The island Barrang Lompo station 1 depth 5m and 10m namely 0,6011% and 0,5504% category ‘being’, station 2 the level of damage/index mortalities 0,7326% category ‘high’
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
