A tropical harpacticoid copepod, Nitocra affinis californica lang as an effective live feed for black tiger shrimp larvae Penaeus monodon fabricius
No full textSurvival and specific growth rates of Penaeus monodon larvae (post-larval stages 1-15), fed with different live feeds and artificial diets, were evaluated using three different treatments, namely: i) Nitocra affinis, ii) combination of Artemia nauplii + N. affinis and iii) artificial diet. The experiment was carried out in 10-L aquaria with 30% daily water exchange for a period of 16 days. The survival rate (61%) and specific growth rate (16.7 %day-1) were highest (p<0.05) in the treatment with shrimp larvae fed with N. affinis. Likewise, the protein contents of N. affinis was found to be the highest (p<0.05) among all the diets used. The fatty acids of N. affinis was dominated by polyunsaturated fatty acids (PUFA) (22:6n3) forming 19.5% of the total PUFA identified. In fact, N. affinis contained the highest (p<0.05) amount of PUFA and the highest (p<0.05) n-3/n-6 ratio amongst the three diets. Analysis of the copepod fed shrimp showed significantly higher (p<0.05) amount of long chain PUFA, both of the n-3 and n-6 series fatty acids, when compared to the artificial diet fed larvae. The results of this study showed that N. affinis has the potential to be used as an effective live feed for P. monodon due to their high PUFA contents and broad size range (nauplii to adults) to cater for different shrimp post-larval stages
UMPSA and CLSU celebrate COAR 2025 focusing on knowledge sharing in Biotechnology and Agriculture
Get PDFGAMBANG, 17 June 2025 - The Faculty of Industrial Science and Technology (FIST), Universiti Malaysia Pahang Al-Sultan Abdullah (UMPSA) has successfully organized the 5th Academic and Research Colloquium (COAR 2025) in collaboration with the College of Fisheries, Central Luzon State University (CLSU), Philippines.
This program is a continuation of the COAR colloquium series that has been taking place since 2021 as an initiative to strengthen international academic and research networks.
The opening ceremony was officiated by Dean of FIST, UMPSA, Associate Professor Dr. Aizi Nor Mazila Ramli, welcoming the presence of Vice-President, Student Affairs CLSU, Professor Dr. Ravelina R. Velasco and Acting Dean of the College of Fisheries, CLSU, Associate Professor Dr. Hazel Monica Matias-Peralta as the main co-organizer of the program
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
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
