Gendered inequalities in campaign finance are generally considered an important impediment to the equal representation of women in parliament. A multivariate analysis of 11,897 Flemish candidates in the Belgian elections from 1999 to 2019 provides strong new evidence of the gender gap in campaign spending, showing that women candidates are significantly outspent by men. But this gender gap is only present after the introduction of strict quota and is limited to non-incumbents. It takes 16 years and five elections after the introduction of strict quotas before this gender gap narrows. In terms of the funding of their campaigns, women draw significantly less money from their personal wealth and receive less money from their parties when strict quotas are in place.

Allanite-(Y), ideally CaY(Al2Fe2+)(Si2O7)(SiO4)O(OH), is a valid species with the type locality in the Åskagen pegmatite, Värmland, Sweden. The mineral occurs as an accessory phase in the blocky zone of the NYF granitic pegmatite near Åskagen, Värmland, Sweden. It forms rims together with iimoriite-(Y), gadolinite-(Y) and allanite-(Nd) around altered crystals of thalénite-(Y). Allanite-(Y) replaced primary thalénite-(Y) during an episode of early post-magmatic hydrothermal activity. Allanite-(Y) forms euhedral crystals with size up to 1 mm, black with a vitreous lustre, conchoidal fracture and greyish brown streak. It has a Mohs hardness of ca. 6, the calculated density of 3.945 g.cm–3 and is biaxial (−) with α = 1.760(3), β = 1.799(2) and γ = 1.784(3) in 589 nm light; pleochroism is weak pale yellowish brown in all directions. Allanite-(Y) has monoclinic symmetry, with the space group P21/m, a = 8.8520(8) Å, b = 5.6959(5) Å, c = 10.0543(9) Å, β = 115.510(2)°, V = 457.52(7) Å3 and Z = 2. Crystal-chemical analysis resulted in the empirical formula: A1(Ca0.900Mn0.090Na0.010)Σ1.000A2(Y0.323Ca0.260Nd0.118Sm0.087Gd0.098Dy0.044Ce0.034Pr0.014Tb0.012Er0.005La0.003Ho0.002Yb0.001)Σ1.001M1(Al0.921Fe2+0.070Ti0.003)Σ0.994M2(Al1.000)M3(Fe2+0.638Fe3+0.262Al0.072Mg0.028)Σ1.000T1(Si1.000)T2(Si1.000)T3(Si1.003)O12.000(OH)1.000.

Allanite-(Y) belongs to the allanite group of the epidote supergroup. The closest end-member compositions of valid allanite group species are allanite-(Ce), allanite-(La) and allanite-(Nd) related via the simple exchange mechanism Y ↔ Ln. The allanite-(Y) origin during metasomatic replacement of the thalénite-(Y) was mainly affected by local system composition and structural constraints rather than Ln+Y fluoride complexation in hydrothermal solution.

For over four decades, isotretinoin has shown unparalleled efficacy in the management of severe recalcitrant acne. However, controversies exist about its psychiatric safety profile. This editorial discusses the alleged causal role of isotretinoin in the development of psychiatric adverse events in light of the best available evidence.

Bombyx mori Tryptophanyl-tRNA synthetase (BmWARS) belongs to the family of Ic-like aminoacyl-tRNA synthetases (aaRSs), whose specific recognition of the substrate Trp, tRNA, maintains the fidelity of protein synthesis. In this study, BmWARS was cloned and characterized from the midgut of the silkworm, Bombyx mori, resulting in an open reading frame (ORF) with a full length of 1,149 bp, which can encode 382 Aa. BmWARS is localized in the cytoplasm, and is expressed in all tissues of the silkworm, with higher expression in the testis, ovary, silk gland and malpighian tubule. The expression of BmWARS was significantly up-regulated in the midgut and silk gland after infection with Bombyx mori nuclear polyhedrosis virus (BmNPV). In addition, overexpression of BmWARS inhibited BmNPV infection and replication extremely significantly, while interference with BmWARS expression promoted BmNPV infection and replication. Analysis of the immune pathways in which BmWARS may be involved revealed that the expression of the key genes of the PI3K-Akt pathway, BmPI3K, BmAkt, BmPDK1, BmeIF4E, BmS6, and p-Akt protein was significantly reduced, whereas the expression of BmPTEN, BmFoxO, and BmCaspase9 was significantly increased in the cells that overexpressed BmWARS and were infected with BmNPV. Meanwhile, the results of the study interfering with the expression of BmWARS were completely opposite to those of the study overexpressing BmWARS. This is the first report that BmWARS has antiviral effects in Bombyx mori. Moreover, BmWARS inhibits BmNPV infection and replication in Bombyx mori cells by promoting apoptosis and inhibiting cell proliferation.

Animals adopt various behavioral strategies to meet their biological needs, often adjusting their activity cycles. While some species restrict their activities to specific periods within the 24-hour light and dark cycle, others are cathemeral, showing flexible activity patterns that include both day and night. This study investigates the cathemeral activity of Amazonian manatees (Trichechus inunguis) in Anavilhanas National Park, Brazil, with a focus on their nocturnal behavior and ecological adaptability. Using thermal cameras, we recorded nocturnal feeding for the first time, highlighting the manatees’ flexibility beyond the typical diurnal–nocturnal cycle. Our findings reveal that manatees adjust their feeding strategies according to seasonal vegetation availability and water levels. Specifically, they feed at night on the riparian plant maracarãna (Coccoloba densifrons), which is only accessible during the flood season. This nocturnal behavior likely helps minimize predation risk and enhances foraging efficiency. These insights significantly improve our understanding of manatee ecological behavior in the Amazon, demonstrating their adaptability to environmental changes. The study underscores the importance of considering cathemeral activity in conservation strategies to ensure the ongoing protection of Amazonian manatees against environmental and human pressures.

One of the persistent obstacles to trade liberalization is a government’s inability to commit and deliver compensation to trade losers. We argue that constitutional structures interact with the geographic profiles of industries to shape a government’s ability to commit to a compensation contract, defined as an interbranch contract whereby an executive branch promises compensation in exchange for legislative support for ratification. Our theory predicts that parliamentary systems are more likely to liberalize and compensate geographically concentrated industries because party leaders enforce a contract with a smaller number of legislators. Presidential systems are more likely to liberalize and compensate geographically diffused industries because legislature enforces a contract with a larger number of legislators. Using novel product-level data on agricultural trade liberalization and remote-sensed cropland in 38 democracies, we find evidence consistent with our argument. Qualitative studies of the sugar industry and interviews with policymakers provide further evidence.

Are people more inclined to help strangers when they’ve experienced similar hardships? People who have experienced displacement could be tremendous allies to the newly displaced, but they are relatively understudied. This study explores how people who have experienced wartime displacement respond to refugees fleeing new violence. I prime Serbs who experienced wartime displacement with either (1) their experience of displacement or (2) their ethnic identity. I then measure their altruism toward Syrian refugees traveling the Balkan route. Compared to participants who were reminded of their ethnic identity, participants who were reminded of their displacement were no more generous toward displaced Syrians. In fact, participants who experienced displacement, as well as wartime violence, were more generous toward the refugees when they were reminded of their ethnic identity. These results suggest that shared hardship alone may not necessarily enhance refugee inclusion. The results further suggest that interventions may benefit from calling out the differences between hosts and refugees—in this case, on the dimension of ethnicity. These findings caution humanitarians to construct their interventions with care.

This paper presents a notched ultra-wideband antenna designed to suppress interference from narrowband communication systems. The antenna features a defected ground structure and a stepped microstrip feedline for improved impedance matching and enhanced bandwidth. A bent slot structure is incorporated into the radiating patch to achieve the band-notched characteristic. It has a wide tunable frequency range which allows for flexible adjustment of the notch frequency. Traditional optimization methods, such as numerical analysis, are computationally expensive and inefficient, while heuristic algorithms are less precise. To address these challenges, an improved one-dimensional convolutional neural network (1DCNN-IPS) model is proposed for optimizing the bent slot design more efficiently. The trained 1DCNN-IPS model can accurately predict the antenna’s electromagnetic parameters, reducing mean squared error and training times compared to traditional methods. This provides an efficient and precise solution for antenna structural optimization.

This article explores the use of speech representation verbs in Late Modern English. Drawing data from CLMET3.0, it focuses on paralinguistic verbs in narrative fiction texts from the eighteenth through the early twentieth centuries, as in blubbered in ‘“And only last Sunday – afternoon,” Mr. Povey blubbered.’ (CLMET3.0; 1908, Bennett, Old Wives’ Tale). The results show a drastic increase of these verbs, both in tokens and types, across the Late Modern English period, especially in direct speech constructions. I argue that this trend is linked to developing conventions for and experimentation with speech representation in the growth of especially the novel in the first half of the nineteenth century and beyond: the paralinguistic verbs offer a flexible tool for writers not only to structure dialogue, but also to convey stance and hence influence reader interpretation of characters, roles, situations and themes. The results underscore the importance of studying literary texts for understanding the general development of speech representation mechanisms in the history of English.
