Induction of Microspore Embryogenesis of Eggplant (Solanum melongena L.) ‘Gelatik’
Full text linkThe haploid or double haploid plant of eggplants could be produced from microspore culture (embryogenesis of microspores). In the breeding programs, microspore can be developed into an embryo directly after exposure to stress treatment during cultured. Stress (temperature and starvation medium) is an important factor in the induction of embryogenesis microspore. This study aims to induced embryogenic microspores from eggplant CV. Gelatik. The stage late-uninucleate microspore (Vacuolate Microspore/VM) and early binucleate (Young Bicellular Pollen/YBP) are the suitable stages to induce multinucleate structure. There are 3 methods used in this research; 1) Determination of the stage development of microspore based on flower buds length and anther length. 2) Induction of embryogenic microspore on the pre-treatment and starvation medium. 3) After giving pre-treatment for 4 days, micropores were transferred to culture medium A2 at 28oC in dark conditions to induce the multicellular structures. This study reported that 50-68.51% of the VM+YBP stage obtained in the range of flower bud lengths of 10-17 mm, and 5.0-6.9 mm, the range of anther length containing VM+YBP of 50-77.48%. The pre-treatment heat shock at 33oC in the medium B for 2 days, produced embryogenic microspores with a high percentage, that is about 50.19%, while microspores at 25oC and 4oC respectively 46.17% and 49.28%. Pre-treatment for 4 days at 4 oC, 25 oC, and 33oC with the percentage of embryogenic microspores apiece 32.87%, 27.45%, and 37.34%. The multicellular (starlike) structure begins forming on the fifth day of incubation in culture medium (A2) after pre-treatment in B medium at 33oC
Sosialisasi Pemanfaatan Ikan Laut sebagai Sumber Pangan Kaya Nutrisi di Desa Bilungala, Kecamatan Bonepantai, Kabupaten Bone Bolango
Full text linkGorontalo Province is one of the provinces that has a wealth of natural resources, especially fishery and marine products. One area that has the highest fish production is Bilungala Village, Bone Bolango Regency. Fish is a food rich in protein, minerals, vitamins, and fatty acids. In addition, fish also contain omega-3 fatty acids and vitamin K which the body needs. All the nutritional content in fish is very influential on the growth and development of children. But in fact, the level of fish consumption in Indonesia is still very low compared to other largest fish-producing countries. Therefore, socialization is carried out through the use of marine fish as a source of nutrient-rich food. The purpose of this service is to provide information to the public about the nutritional content of fish, increase fish consumption in the community, and increase the hobby of eating fish. The location of service is carried out in Bulungala Village, Bonepantai District, Bone Bolano Regency, Gorontalo Province. The target of this service is the people of Bilungala Village, especially PKK women with activities carried out in November 2022. The activities consist of the preparation, implementation, and closing stages. In the preparatory stage, a survey was carried out in the village, then in the implementation stage, socialization was carried out to the community through the provision of material and ended with a discussion/question and answer regarding the material presented
Pemanfaatan Hasil Tangkapan Ikan Dengan Pelatihan Pembuatan Sossis Ikan Di Desa Bilungala Kecamatan Bonepantai Kabupaten Bone Bolango
Full text linkOne of the areas in Gorontalo Province that has fishery potential from Tomini Bay is Bilungala Village, where the most commonly caught fish is Cakalang (Katsuwonus pelamis). Cakalang has a fairly high economic value and is much preferred because it has good meat density, especially to be used as a source of protein. But so far, the community does not have much knowledge about the management of Cakalang, which is the main catch. One of the processed products that can be made with Cakalang is fish sausage. Sausage is a food product that has nutritional value and meets the needs of the body. This processed product is also more practical to serve. The resulting product can also be an alternative business to improve the community's economy. Therefore, a fish processing training activity was carried out in the form of cakalang fish sausage. The aim of this training is to equip housewives in the village with skills in processing fish catches into nutritious and durable food products. The location of this community service activity was carried out in Bilungala Village, Bonepantai District, Bone Bolango Regency. The target is housewives in the village. The activity was carried out on November which consisted of the preparation stage by conducting a survey and the implementation stage by conducting training with direct demonstrations and together with the participants making the product. This activity went smoothly. Participants were very enthusiastic about participating in the activity from the beginning of the activity to the end of the activity. This activity requires follow-up in the form of marketing training for processed fish products in the form of fish sausage. The training can be an asset for participants consisting of housewives to market their products which in the end are able to increase their income and help the community's economy
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
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
