Populism’s effects on democracy after populists gain control of government (hereafter, populist incumbents) are some of the best theorized and documented consequences. The argument that populist incumbents threaten institutions of democratic contestation—and, less frequently, that they correct some aspects of political participation and representation—has been made from multiple approaches.1 Scholars and commentators often cite specific cases of populists harming democracy and, since 2016, several large-N studies have confirmed their negative impact. Specifically, studies repeatedly show the harmful effects of populist incumbents on civil liberties, including media freedom, horizontal accountability, and electoral integrity in both electoral and liberal democracies. Research has been less consistent in showing the positive consequences of populist incumbents, especially for democratic representation and political participation.

This article revisits Rayford Logan’s thesis in The Negro in American Life and Thought: The Nadir, 1877‒1901 to chart how African Americans experienced joy during a racial low point—“the Nadir” of race relations. Using Logan’s claims as a conceptual framework, the article examines W. E. B. Du Bois’s position on amusement and everyday Black people’s joyful acts during the post-Reconstruction period to understand “a paradox of pleasure”—feeling jovial during dark times. With the Nadir as a case study, this essay argues that historians may develop Black joy as a historical analytic by asking research questions about Black affect, employing the tools of historical imagination, and concentrating on the small delights of daily life. This essay seeks to inspire curiosity about how exploring Black life from the angle of elation, not sorrow, can produce complex histories of Black subjectivity and feeling. It proposes Black joy as an inchoate analytic in hopes of it becoming a formal mode of historical inquiry.

A classical result of Erdős, Lovász and Spencer from the late 1970s asserts that the dimension of the feasible region of densities of graphs with at most k vertices in large graphs is equal to the number of non-trivial connected graphs with at most k vertices. Indecomposable permutations play the role of connected graphs in the realm of permutations, and Glebov et al. showed that pattern densities of indecomposable permutations are independent, i.e., the dimension of the feasible region of densities of permutation patterns of size at most k is at least the number of non-trivial indecomposable permutations of size at most k. However, this lower bound is not tight already for $k=3$. We prove that the dimension of the feasible region of densities of permutation patterns of size at most k is equal to the number of non-trivial Lyndon permutations of size at most k. The proof exploits an interplay between algebra and combinatorics inherent to the study of Lyndon words.

This article reconsiders the sixteenth-century Idealist Neo-Confucian philosophy of Wang Yangming (1472–1529) in light of the development of twentieth-century Latin American liberation theology. After defining liberation theology, this study identifies the crucial contributions made to it by Emmanuel Levinas’s assertion of the primacy of ethics over ontology and critique of the egocentric nature of Western philosophy. It then delineates the epistemological and deontological criticisms made of Roman Catholic orthodoxy—and institutionalized Christianity in general—by Latin American liberation theologians, particularly Enrique Dussel and José Porfirio Miranda. These are compared with Wang’s critique of the Rationalist Neo-Confucianism that had been official orthodoxy and the legitimating philosophy for imperial China for three centuries. The study finds that Wang’s Idealist philosophy incorporates epistemological, spiritual, and ethical perspectives with powerful democratic and liberationist elements that prefigure the development of late-twentieth-century Latin American liberation theology. Thus, contrary to the conventional view of Confucianism as a conservative philosophy, these elements in Wang’s Neo-Confucianism render it a theology (or philosophy) of liberation.

This study introduces an innovative methodology for mortality forecasting, which integrates signature-based methods within the functional data framework of the Hyndman–Ullah (HU) model. This new approach, termed the Hyndman–Ullah with truncated signatures (HUts) model, aims to enhance the accuracy and robustness of mortality predictions. By utilizing signature regression, the HUts model is able to capture complex, nonlinear dependencies in mortality data which enhances forecasting accuracy across various demographic conditions. The model is applied to mortality data from 12 countries, comparing its forecasting performance against variants of the HU models across multiple forecast horizons. Our findings indicate that overall the HUts model not only provides more precise point forecasts but also shows robustness against data irregularities, such as those observed in countries with historical outliers. The integration of signature-based methods enables the HUts model to capture complex patterns in mortality data, making it a powerful tool for actuaries and demographers. Prediction intervals are also constructed with bootstrapping methods.

This treatise, possibly written between 541 and 557 (1147–1162), illuminates the perspectives of a subaltern group persecuted by the Nizari Ismaili hierarchy for agitating to bring about the manifestation (ẓuhūr) of their imam. Ismailis in Iran awaited the manifestation of a descendant of Nizār b. al-Mustanṣir who was killed in Cairo in 488/1095 after a failed attempt to succeed his father as the Fatimid imam-caliph. In 559/1164, the fourth ruler of the Nizari polity proclaimed the Qiyāmat-i buzurg (the Great Resurrection) and was subsequently recognized as the Nizari imam. This text records how its author construed the transference of imamate from Egypt to Iran. It structured continuities between the Fatimid and Nizari daʿwa (summons) and between communities of followers of Nāṣir-i Khusraw and Ḥasan-i Ṣabbāḥ, the founder of the Nizari Ismaili polity. If the dating is correct, then the Ḥikāyat is one of the earliest known Nizari texts and is a very early exemplar of the Nizari appropriations of the poet, philosopher, and Fatimid dāʿī (summoner), Nāṣir-i Khusraw.

The GESAH Graphic Arts Ontology (GESAH GAO) was developed to describe works of art on paper such as prints and drawings. The design was guided by the content-related, specialized needs of the domain experts, as well as the requirement to record the data in a structured manner in order to enable subsequent use and to ensure technical connectivity to current and future developments. The ontology models cultural objects by means of activities related to them (creation, production, inscription, preservation, exhibition etc.), people/organizations and their roles, subjects depicted and other relevant concepts. It incorporates concepts from upper ontologies such as the Basic Formal Ontology (BFO) and reuses classes and properties from ontologies such as Friend of a Friend (FOAF), VIVO, and Simple Knowledge Organization System (SKOS). With TIB SAH digital, we show the reference implementation of the GESAH GAO. It was constructed using the open-source knowledge graph suite Vitro, which provides custom entry forms for cataloguing and public access to the digitized collection.

The letters sent by the English composer Michael Tippett from Wormwood Scrubs Prison, where, a conscientious objector, he spent two months in summer 1943, form a remarkable and important sequence, illuminating not only Tippett's life and compositions but the experience of a gaoled objector to the Second World War. Four prison letters had been thought to survive, documenting in detail his imprisonment, which included turning pages for Benjamin Britten during a recital in the chapel, and conducting the prison orchestra. In 2023 a fifth letter was found, its discovery reported in the national press.1 Its publication is intended to complement the previously released documents, completing what is now a series of five until such time as a collected edition of Tippett's letters, of which only a fifth has seen print, can be undertaken.2

The year 2024 marks an important double anniversary for the journal The Americas. On the one hand, it marks 80 years of publication, with the first issue dated July 1944. On the other, it marks the quincentenary of the arrival of the first Franciscans to North America, when the first group of missionary friars landed in what is now Mexico. The history of the journal is rooted in the Franciscan Order. In April 1944 Franciscan historians from throughout North America met in Washington, DC, and founded the Academy of American Franciscan History. The goal of the Academy, as articulated in the records of that inaugural meeting is to “discover and assemble documents and books of Franciscan interest, to compile a complete bibliographical index of American Franciscana, to edit and publish documents, and to issue original historical works.”1 The Academy additionally pledged to publish a journal, a quarterly review of inter-American cultural history: The Americas.

Art librarians work with images. It’s one of the things that separates us from many of our fellow subject librarians. As the academy continues to grapple with the benefits, drawbacks, and effects of AI, art librarians are uniquely positioned to teach students how to critically engage with AI image generators. Considerations concerning copyright, bias in datasets, formal analysis, and AI image generators’ potential as an art medium are some examples of topics that art librarians have at their disposal.
