Get PDFPenelitian ini bertujuan untuk melakukan analisis teknikal terhadap saham-saham syariah di sektor pertambangan dengan menggunakan Indikator Fibonacci Retracement dan Moving Average Convergence Divergence (MACD). Dalam penelitian ini, data pergerakan harga harian saham, termasuk harga pembukaan, harga penutupan, harga tertinggi, dan harga terendah, direpresentasikan melalui grafik saham yang diakses melalui situs tradingview. Metode penelitian yang digunakan adalah metode kuantitatif, dengan populasi penelitian terdiri dari seluruh perusahaan tambang yang terdaftar di Jakarta Islamic Index (JII) dalam periode 1 Mei 2022 hingga 1 Mei 2023. Jumlah sampel yang diambil sebanyak 11 perusahaan, yaitu Aneka Tambang Tbk (ANTM), Bukit Asam Tbk (PTBA), United Tractors Tbk (UNTR), Adaro Energy Indonesia Tbk (ADARO), Bumi Resources Minerals Tbk (BRMS), Barito Pacific Tbk (BRPT), Harum Energy Tbk (HRUM), Vale Indonesia Tbk (INCO), Indika Energy Tbk (INDY), Indo Tambangraya Megah Tbk (ITMG), dan Merdeka Copper Gold Tbk (MDKA). Teknik pengambilan sampel yang digunakan adalah teknik purposive sampling, di mana pemilihan sampel didasarkan pada pertimbangan tertentu
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
Uji Efek Imunomodulator dari Ekstrak Daun Kersen (Muntingia calabura L.) Dengan Metoda Carbon Clearance Terhadap Mencit Putih Jantan
Get PDFTumbuhan kersen (Muntingia calabura L.) merupakan tanaman yang berpotensi dikembangkan sebagai obat yang secara tradisional digunakan sebagai obat analgetik dan antiradang. Penelitian ini bertujuan untuk mengetahui aktivitas imunomodulator ekstrak etanol tumbuhan kersen dengan metode carbon clearance serta jumlah total leukosit dan persentase sel leukosit mencit putih jantan. Pengujian dilakukan pada 25 ekor mencit putih jantan yang dibagi menjadi 5 kelompok. Kelompok 1 (kontrol negatif) diberi suspensi Na CMC 0,5%, kelompok 2, 3, dan 4 diberi suspensi ekstrak daun kersen dengan dosis 50; 100; dan 200 mg/kgbb; dan kelompok 5 (kontrol positif) diberi obat Imboost dengan dosis 15 mg/kgbb. Ekstrak etanol daun kersen diberikan selama enam hari secara oral dan pada hari ke tujuh ditentukan indeks fagositosis, jumlah sel leukosit, persentase jenis sel leukosit, dan persentase bobot limpa relatif. Hasil penelitian menunjukkan bahwa indeks fagositosis kelompok kontrol adalah 1,000, kelompok dosis 50 mg/kgbb adalah 1,095, kelompok dosis 100 mg/kgbb adalah 1,469, kelompok dosis 200 mg/kgbb adalah1,745 , dan kelompok pembanding imboost 15 mg/kgbb adalah 2,054. Hasil indeks fagositosis menyatakan bahwa ekstrak etanol daun kersen bersifat imunostimulan karena indeks fagositosis besar dari satu (IF>1). Berdasarkan uji ANOVA dua arah dan dilanjutkan dengan uji Duncan terdapat perbedaan yang signifikan (p<0,05) terhadap indeks fagositosis dan berdasarkan uji ANOVA satu arah dan dilanjutkan dengan uji Duncan terdapat pebedaan yang signifikan (p<0,05) terhadap persentase jenis sel leukosit, jumlah total sel leukosit, dan bobot limpa relatif. Hasil tersebut menunjukkan ekstrak daun kersen pada dosis 50, 100,dan 200 mg/kgbb memiliki aktivitas imunostimulan terhadap mencit putih jantan
