Chemistry learning heavily relies on laboratory activities that provide direct experiences for students to discover concepts and facts, thereby allowing them to develop scientific thinking skills and construct knowledge to enhance understanding of the subject matter. However, several challenges persist in implementation, such as time constraints and inadequate availability of instructional materials that facilitate laboratory activities. Therefore, this research aims to develop a Guided Inquiry-Based Electronic Practicum Module Integrated with STEAM on Thermochemistry for Grade XI High School to address these issues. This study follows the research and development model by Borg and Gall, employing a descriptive quantitative method. The stages include preliminary needs analysis, electronic module development, validation by content and language experts yielding scores between 80-100%, and media experts scoring between 80-90%. The inter-rater reliability test using the interclass correlation coefficient (ICC) yielded 0.91 for content and language experts and 0.96 for media experts. The feasibility test of electronic module on teachers resulted in an average rating between 89-95%. Meanwhile, small-scale and large-scale trials on students showed average ratings ranging from 88.4-91% and 89.65-92.23%, respectively. Based on these evaluations, the developed electronic module is deemed suitable for use by both teachers and students
IDENTIFIKASI VARIASI SEKUEN OVULATION RATE GENE PADA SAPI LIMOUSIN KEMBAR DI PACITAN JAWA TIMUR
No full textKonsumsi daging sapi di Indonesia terus mengalami peningkatan setiap tahun, namun produksi daging sapi nasional hanya mampu mencukupi 65% dari kebutuhan dalam negeri. Oleh karena itu, diperlukan terobosan inovasi baru yang dapat meningkatkan produktivitas ternak sapi, salah satunya dengan kelahiran kembar pada sapi. Sehingga diperlukan identifikasi gen kembar pada sapi agar dapat dilakukan seleksi terhadap sapi yang memiliki potensi untuk melahirkan kembar. Identifikasi variasi sekuen ovulation rate geneperlu dilakukan untuk meningkatkan pembibitan sapi Limousin kembar. Identifikasi variasi sekuen ovulation rate gene dimulai dengan pengambilan sampel darah sapi. Kemudian dilakukan isolasi DNA darah sapi, amplifikasi sekuen ovulation rate gene, elektroforesis horizontal, lalu dilanjutkan sekuensing. Hasil sekuensing kemudian dianalisis menggunakan software bioinformatika untuk melihat adanya variasi sekuen serta untuk melihat prediksi polipeptida yang terbenntuk yang kemungkinan berperan dalam laju ovulasi sapi Limousin.Berdasarkan hasil analisis, prediksi polipeptida yang terbentuk adalah Cytokine (TNF Tumor Necrosis Factor). Hal ini memperlihatkan bahwa variasi yang terjadi tidak dapat mengubah polipeptida yang terbentuk, karena polipeptida yang terbentuk dari ketiga sampel merupakan golongan sitokin yang memiliki fungsi untuk proses ovulasi pada mamalia. Dengan demikian dapat disimpulkan bahwa adanya variasi sekuen gen tidak mengubah fungsi gen dapat dikatakan gen ini gen conserve. Pada akhirnya sapi ini dapat dilakukan seleksi, konservasi dan pemuliaan untuk meningkatkan produktivitas sapi, guna mencukupi permintaan daging sapi yang tinggi
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
