The American state was a republic of patrons and clients throughout the Long Nineteenth Century. Unequal ties of hierarchy and reciprocity went far beyond the partisan administration and electioneering that we associate with the spoils system. As a form of “belated feudalism,” clientelism proved resilient because it was a familial property relation embedded within a diverse and changing society. Officeholding politics subsumed a host of racialized and gendered dependents—White men of lower status, women, children, and the enslaved—into the penumbra of the state, which itself was governed via the extended party household. What elements of patron–client relations endured or changed from the colonial inheritance until the New Deal? This article reinterprets the republic’s classical age, first, by exploring the origins of party patrimonialism, and then, by examining the dynamics of officeholding political economy and the rise of markets for patronage. Political rule before the New Deal had a different orientation. Clientelism fused older lineages of dependence with the kind of profit-seeking exchanges typical of the burgeoning capitalist economy. It was this mixed state, at once patrimonial and capitalist, that proved so difficult to reform at the turn of the twentieth century.

Azooxanthellate corals of Rhizangiidae, with their distinctive morphological and ecological features, are widely distributed across global oceans but remain under-studied due to identification challenges. Comprehensive underwater surveys across diverse marine habitats such as rocky reefs and submerged shipwrecks were undertaken, and findings highlighted the exclusive presence of Culicia stellata in natural rocks, off the coast of Kaup for the first time in Indian EEZ. The study also records the presence of Cladangia exusta, nearly six decades after the first record from off Cochin, Laccadive Sea. This research presents a detailed study of the taxonomic description, distribution, and ecological preferences of Cladangia exusta and Culicia stellata in the Laccadive Sea. This study underscores the importance of accurate species identification for effective conservation strategies and enriching biodiversity records.

Mass public opinion on globalization shows a persistent gender gap, but explanations for this gap differ. In the context of Africa, understanding this gender gap is particularly important because of women’s growing representation in legislatures and the rapid expansion of global economic flows on the continent. Why are women on average more skeptical of foreign economic actors? We consider this question across Sub-Saharan African countries, using Chinese economic engagement as a salient, visible form of economic globalization. Numerous studies have explored the impact of China’s presence on Africans’ attitudes toward China, but we know little about a documented gender gap in these attitudes. We explore the roots of this gap from an angle of economic vulnerability, positing that women at higher risk of a negative economic impact of Chinese engagement are more likely to view China negatively than their male counterparts. Using multilevel analyses of up to 84,000 respondents from up to 37 countries, we find a consistent pattern of economic vulnerability explaining the gender gap in attitudes, and factors associated with economic security mitigating it. Our findings suggest that economic vulnerability shapes attitudes differently across genders, and that increasing representation of women in African legislatures may have implications for policies toward Chinese engagement.

Infants of diabetic mothers are neonates born to a woman who had periodic hyperglycaemia during pregnancy. Consequently, infants of diabetic mothers are at higher risks of illness besides morbidity and mortality due to teratogenic effects on the fetal cardiovascular system, causing most frequent CHDs. The primary purpose of this review is to present, on this topic, a better-comprehended review covering pertinent material and data to be informed of severe risks to a newborn’s cardiac system and function. These conditions can affect maternal, fetal, neonatal, and future adult health. Further research should be addressed towards the early detection of diabetes, its magnitude, and management. Immediate interventions should be proposed to lessen the diabetes burden and its adversative effects during the prenatal period.

Morphological and molecular methods were used to describe a new species of Trapania Pruvot-Fol, 1931 from shallow water kelp forests on the north-central coast of Peru. The new species, Trapania huarmeyana sp. nov., is distinguished from other species along the Eastern Pacific by external morphological characters such as its translucent white body with brown stripes and small spots on the dorsum, blotches on the base of the extra-branchial processes, extra rhinophoral processes and gill branches. Internally, T. huarmeyana sp. nov. is distinguishable by several morphological characteristics of the radula, jaws and genital organs. Phylogenetic trees recovered using Bayesian Inference and Maximum Likelihood analysis of DNA sequences support its distinct status and clarify its relationship to other species from the Eastern Pacific. This new species constitutes the first record of Trapania from the Humboldt Current Ecosystem, contributing to our understanding of the distribution of the genus in the South-eastern Pacific.

We prove a result on equilibrium measures for potentials with summable variation on arbitrary subshifts over a countable amenable group. For finite configurations v and w, if v is always replaceable by w, we obtain a bound on the measure of v depending on the measure of w and a cocycle induced by the potential. We then use this result to show that under this replaceability condition, we can obtain bounds on the Lebesgue–Radon–Nikodym derivative $d (\mu _\phi \circ \xi ) / d\mu _\phi $ for certain holonomies $\xi $ that generate the homoclinic (Gibbs) relation. As corollaries, we obtain extensions of results by Meyerovitch [Gibbs and equilibrium measures for some families of subshifts. Ergod. Th. & Dynam. Sys. 33(3) (2013), 934–953], and García-Ramos and Pavlov [Extender sets and measures of maximal entropy for subshifts. J. Lond. Math. Soc. (2) 100(3) (2019), 1013–1033] to the countable amenable group subshift setting. Our methods rely on the exact tiling result for countable amenable groups by Downarowicz, Huczek, and Zhang [Tilings of amenable groups. J. Reine Angew. Math. 2019(747) (2019), 277–298] and an adapted proof technique from García-Ramos and Pavlov.

Although nudibranchs are common and attractive animals, our understanding of these marine gastropods in Vietnam remains limited. Prior research has suggested that combining morphological examination with molecular analysis results in more accurate identification of nudibranchs. However, previous studies in Vietnam have typically relied solely on morphological methods for nudibranch identification. In this study, the nudibranch species Halgerda batangas was recorded in Vietnam for the first time based on both morphological and molecular approaches. Halgerda batangas was characterized by a network pattern consisting of orange lines, relatively low dorsal tubercles with red-orange caps and white basal rings, and an orange line along the foot margin. Molecular analysis corroborated the morphological findings. These results suggest that integrating morphological and molecular methods is an effective approach for identifying nudibranchs.

This article describes Hilbert spaces contractively contained in certain reproducing kernel Hilbert spaces of analytic functions on the open unit disc which are nearly invariant under division by an inner function. We extend Hitt’s theorem on nearly invariant subspaces of the backward shift operator on $H^2(\mathbb {D})$ as well as its many generalizations to the setting of de Branges spaces.

Isolated native pulmonary valve endocarditis is rare. We present a rare case of isolated native pulmonary valve endocarditis resulting in severe right ventricular outflow tract obstruction in an immunocompetent patient with surgically repaired ventricular septal defect caused by Burkholderia cepacia.
