    Environmentally friendly aquaculture for effective fish production is currently urgently needed by the community. Aquaculture develops every year according to the dynamics of market needs and demands as well as optimal fishing. For this reason, it is necessary to develop integrated aquaculture cultivation that is able to complement the needs of protein from fish for the community. Students or students as the younger generation have a strategic role as a group capable of making changes. As part of the agents of change in society, the role of students as fish cultivators can be increased for the benefit of talent and specialization, coaching, training and service to the community. The development of aquaculture can act as an entry point for the growth of other businesses related to aquaculture. The feed industry, cultivation facilities and infrastructure can develop around the area, especially urban areas or cultivation centers. Agricultural/fishery extension agents can enter through this activity to improve technical services. Likewise, elements of higher education as coaches of students in schools to develop talents and agents of change in society. Service activities use the direct participation method by hatching catfish which includes: providing cultivation material with lectures followed by discussions, implementing cultivation with direct practice at partners\u27 places, coaching and mentoring

    JUMLAH SEL DARAH MERAH DAN NILAI HEMATOKRIT DARAH IKAN NILEM (Ostheocilus vittatus) YANG DI PELIHARA PADA SISTEM GREEN WATER TECHNOLOGY

    Green water merupakan teknologi budidaya ikan yang berfokus pada media pemeliharaan ikan. Media pemeliharaan ikan bersamaan dengan penumbuhkan pythoplankton. Penggunaan phytoplankton ini dapat meningkatkan kualitas air dan sumber pakan alami untuk ikan. Ikan nilem merupakan ikan air tawar yang memiliki nilai potensial ekonomi yang tinggi dan menjadi komoditas unggulan. Oleh karena itu produktivitasnya harus selalu dijaga. Penelitian ini bertujuan untuk mengetahui pengaruh media green water pada jumlah sel darah merah dan nilai hematokrit darah ikan nilem. Penelitian dilakukan dengan empat perlakuan dan empat ulangan. Hasil peneltian menunjukkan adanya perbedaan yang nyata antara perlakuan media green water dengan perlakuan kontrol. Perlakukan P3 menjadi perlakukan dengan hasil terbaik. Peningkatan jumlah sel darah merah dan nilai hematokrit darah ikan nilem dikarena kandungan nutrisi yang banyak pada plankton Spirulina sp dan Chlorella sp pada perlakuan P3. Kandungan zat besi dan zat aktif phycocianin yang mampu menginduksi sel narrow yang ada pada sum sum tulang belakang sehingga mampu meningkatkan jumlah sel darah merah dan nilai hematokrit darah ikan nilem. 

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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
