ABC-CapsNet: Attention based Cascaded Capsule Network for Audio Deepfake Detection
No full textIn response to the escalating challenge of audio deepfake detection, this study introduces ABC-CapsNet (Attention-Based Cascaded Capsule Network), a novel architecture that merges the perceptual strengths of Mel spectrograms with the robust feature extraction capabilities of VGG18, enhanced by a strategically placed attention mechanism. This architecture pioneers the use of cascaded capsule networks to delve deeper into complex audio data patterns, setting a new standard in the precision of identifying manipulated audio content. Distinctively, ABC-CapsNet not only addresses the inherent limitations found in traditional CNN models but also showcases remarkable effectiveness across diverse datasets. The proposed method achieved an equal error rate EER of 0.06% on the ASVspoof2019 dataset and an EER of 0.04% on the FoR dataset, underscoring the superior accuracy and reliability of the proposed system in combating the sophisticated threat of audio deepfakes
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Pengembangan media pembelajaran kanel Wani untuk meningkatkan pemahaman Konsep unsur-unsur lingkaran Di sekolah dasar
No full textLatar belakang yang mendasari penelitian ini adalah rendahnya pemahaman konsep peserta didik terhadap unsur-unsur lingkaran pada mata pelajaran Matematika. Berdasarkan latar belakang tersebut, berikut beberapa identifikasi masalah yang terdapat dalam penelitian ini, yaitu 1) Rendahnya pemahaman konsep peserta didik pada pembelajaran, 2) Faktor – faktor negatif yang mempengaruhi rendahnya pemahaman konsep peserta didik, dan 3) Kurangnya kreatifitas guru dalam mengembangkan media pembelajaran yang bertujuan meningkatkan pemahaman konsep melalui pembelajaran yang menyenangkan.
Desain penelitian ini menggunakan R&D dengan sampel yang dipilih adalah siswa kelas VI SDN 3 Tubanan dengan jumlah 22 siswa sebagai kelas kontrol dengan metode pembelajaran ceramah dan SDN 6 Tubanan dengan jumlah 20 siswa sebagai kelas eksperimen yang menerapkan media Kanel Wani. Efektivitas diukur melalui uji ketuntasan, uji peningkatan, uji banding hasil belajar, serta analisis aktivitas.
Hasil penelitian menunjukkan bahwa desain yang dikembangkan menghasilkan produk yang lebih besar ukurannya, lebih detail dalam menunjukkan unsur-unsur lingkaran, dan dilengkapi dengan buku panduan penggunaan media pembelajaran kanel wani. Hasil uji efektivitas menunjukkan siswa yang mendapat media pembelajaran kanel wani memiliki presentase ketuntasan mencapai 100%, n-gain berada dalam kategori tinggi, serta rata-rata hasil belajar siswa kelas eksperimen sebesar 89 dan lebih tinggi dibanding kelas kontrol sebesar 64. Skor rata-rata aktivitas siswa kelas ekperimen sebesar 93,75 lebih tinggi dibandingkan kelas kontrol yakni 51,53.
Berdasarkan penelitian yang dilakukan dapat disimpulkan bahwa penerapan media pembelajaran kanel wani efektif dalam meningkatkan pemahaman konsep dan aktivitas belajar siswa kelas VI SD di Kabupaten Jepara
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Performance evaluation of induced mutant lines of black gram (Vigna mungo (L.) Hepper)
No full textArticle Details: Received: 2020-01-12 | Accepted: 2020-03-02 | Available online: 2020-06-30https://doi.org/10.15414/afz.2020.23.02.70-77 Present investigation was carried out to explore the possibility of inducing genetic variability for yield and yield contributing traits in well-adapted variety PU-19 of black gram (Vigna mungo (L.) Hepper) following mutagenesis with methyl methane sulfonate (MMS), sodium azide (SA) and hydrazine hydrate (HZ). A considerable increase in mean values for fertile branches per plant, pods per plant and total plant yield was noticed among the mutant lines in M4 and M5 generations. Estimates of genotypic coefficient of variation, heritability and genetic advance for yield and yield components were also recorded to be higher compared to control. MMS followed by SA and HZ showed highest mutagenic potential for improving total plant yield of black gram var. PU-19. Treatment concentration 0.3% was found to be most effective in generating significant increase in total plant yield of black gram var. PU-19. The increased genetic variability for yield and yield components indicates the ample scope of selection for superior mutants in subsequent generations due to preponderance of additive gene action.Keywords: black gram, mutagenesis, chemical mutagens, genetic variability, yield componentsReferences AHLOOWALIA, B., MALUSZYNSKI, M. and NICHTERLEIN, K.(2004).

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
