However, <i>G. rubrum</i> can be clearly distinguished from <i>G. elatum</i> on the basis of several distinctive characters which include: flower diameter (2.2–2.8 cm in <i>G. rubrum</i> vs. 3.0– 3.5 cm in <i>G. elatum</i>), shape of pseudo-sepal (elliptic or lanceolate vs. ovate), type of hairs on calyx (glandular vs. aglandular), color of petals (red vs. yellow), anther attachment (dorsifixed vs. basifixed), number of carpels (6–8 vs. 10–24) and achene size (7.8–8.0 × 1.6–1.8 mm vs. 3.7–3.9 × 0.9–1.1 mm) (Figures 2 & 3 <b>)</b>. A detailed comparison of these delimiting characters between <i>G. rubrum</i> and <i>G. elatum</i> is provided in Table 1.</p> Description <p> Perennial herb, root fibrous, terete, 0.6–0.8 cm in diameter, fascicled.

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
Review of Fighting Feelings: Lessons in Gendered Racism and Queer Life by Gulzar R. Charania (University of British Columbia Press)
No full textIn Fighting Feelings: Lessons in Gendered Racism and Queer Life, Gulzar R. Charania explores the gendered racialization of women of color through a plethora of interviews with her participants, paying specific attention to the intersection of identities that these women hold such as gender, race, sexuality, age, and socio-economic status. Charania centers the thoughts and experiences of racialized Black and women of color feminists to provide her readers with critical tools to navigate the lived experiences of racialized women while also acknowledging the violence of dominant narratives entrenched in white supremacy. By attending to the practices of scholars and theorists as well as the lives of her participants, Charania urges readers to reconsider the convergence of gender and sexuality in racialized hierarchies
"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
