Time-varying flow-induced forces on bodies immersed in fluid flows play a key role across a range of natural and engineered systems, from biological locomotion to propulsion and energy-harvesting devices. These transient forces often arise from complex, dynamic vortex interactions and can either enhance or degrade system performance. However, establishing a clear causal link between vortex structures and force transients remains challenging, especially in high-Reynolds-number nominally three-dimensional flows. In this study, we investigate the unsteady lift generation on a rotor blade that is impulsively started with a span-based Reynolds number of 25 500. The lift history from this direct-numerical simulation reveals distinct early-time extrema associated with rapidly evolving flow structures, including the formation, evolution and breakdown of leading-edge and tip vortices. To quantify the influence of these vortical structures on the lift transients, we apply the force partitioning method (FPM) that quantifies the surface pressure forces induced by vortex-associated effects. Two metrics – $Q$-strength and vortex proximity – are derived from FPM to provide a quantitative assessment of the influence of vortices on the lift force. This analysis confirms and extends qualitative insights from prior studies, and offers a simple-to-apply data-enabled framework for attributing unsteady forces to specific flow features, with potential applications in the design and control of systems where unsteady aerodynamic forces play a central role.

By focusing on the American Protective Association (A.P.A.), this article demonstrates how anti-Catholicism influenced free labor ideologies and working-class movements during the Gilded Age. The labor movement in the late nineteenth century generally believed that the so-called “dangerous classes” threatened working-class social mobility and economic independence. Religious bigotries, though, often dictated which people and institutions were considered economically dangerous. This article argues that, as anti-Catholic stereotypes collided with emergent anti-monopoly critiques, some working-class reformers saw Catholicism as incompatible with traditional notions of free labor. These reformers embraced anti-Catholic politics and chose to establish, join, or support the A.P.A. Many in the A.P.A. thought Catholic workers lacked the autonomy necessary to be free laborers, leading to intra-union conflict and a distrust of labor organizations with significant Catholic membership. They also charged that the Catholic Church itself opposed free labor and was already profiting off slave labor in institutions like the Houses of the Good Shepherd, a charitable institution, which sought to reform “abandoned women.” Ultimately, the A.P.A. and its anti-Catholic bigotries contributed to the fragmentation of the working class in Gilded Age America in ways that scholars have not yet recognized.

The increasing pollution of water bodies by tetracycline (TC) has emerged as a looming threat to both environmental sustainability and human health, and the development of novel and effective remediation techniques is essential. The purpose of the present research was to explore the potential of montmorillonite (Mnt) and ZnO/Mnt composites as cost-effective and eco-friendly adsorbents for the removal of TC from polluted water sources. Batch adsorption experiments were carried out under controlled laboratory conditions, where adsorption isotherms, kinetic studies, and zero-charge point (pHzcp) determinations were performed systematically to evaluate the performance of ZnO, Mnt, and ZnO/Mnt composites. The results highlighted the underlying importance of surface charge to adsorption by establishing pHzcp for ZnO, Mnt, and the ZnO/Mnt composite. The effects of pH on the surface charge of adsorbents (ZnO, Mnt, and the ZnO/Mnt) and the equilibrium structure of TC were measured systematically and trends that are imperative for understanding the dynamics of adsorption were identified. The removal efficiencies of TC at the optimal pH of 5 were 100% for Mnt, 70% for ZnO/Mnt, and 4% for ZnO. Mnt exhibited the greatest adsorption capacity (125 mg g–1), particularly effective within the pH range of 3–7, demonstrating its strong potential for pollutant removal. However, the ZnO/Mnt composite, although showing a lower adsorption capacity (72 mg g–1), offers additional advantages due to the photocatalytic properties of ZnO. Under light irradiation, ZnO promotes the mineralization of adsorbed TC into harmless products such as CO₂ and H₂O, thereby reducing the risk of secondary pollution. While Mnt alone efficiently captures TC, the lack of degradation may pose environmental challenges. By integrating adsorption with photocatalysis, the ZnO/Mnt composite provides a more sustainable, dual-functional approach, highlighting the significance of coupling pollutant capture with degradation for effective and eco-friendly water treatment.

Given the ubiquity of organizational change, it is fitting that considerable research has focused on employees’ responses to change, much of it collated in review articles. With the aim of integrating this diverse review literature and providing an employee-centric theorization, we provide a meta-review, a systematic review of reviews. We present the meta-construct of employee change orientation (EChO), which aggregates employee responses, attitudes, behaviors, and the associated psychological mechanisms related to organizational change. Our meta-review includes 50 scholarly reviews published between 2001 and June 2025, drawing on 1,606 primary studies. Through a synthesis of these reviews, we present the EChO framework and taxonomy. We identify areas for improvement, particularly for research design, and generate key insights for change practitioners working with employees experiencing change. Our meta-review contributes by clarifying well-researched areas, extending theorizing, and highlighting the need for further research to understand how employee responses to change influence outcomes.

This article examines white Americans’ concern about jazz dancing around the turn of the twentieth century. Drawing from primary sources in national publications, newspapers, and the archives of the Southern Baptist Convention, the essay finds patterns in the response to jazz dancing that set the stage for the making of moral concern throughout the twentieth century. A focus on young people, interracial sex, the emerging specter of homosexuality, black musical forms, immigrants, and traditional gender roles amounted to what I call “Downfall Voyeurism,” in which American decline is portrayed as a spectacle that elicits both fear and titillation. Downfall Voyeurism helps explain the rise and fall of the jazz panic of the 1910s, but it also presages the central tactics of the New Right that historians more traditionally see as emerging in the 1970s and 1980s.
