This paper explores the implementation and enduring significance of the German language program in Milwaukee Public Schools between 1867 and 1918. Despite the German language program facing challenges, notably the Bennett Law of 1889—which sought to restrict foreign language instruction statewide—the program persisted, highlighting the tension between local identity and state mandates. This study argues that the creation of the German course initiated a process of consolidation and standardization in Milwaukee Public Schools, shifting decision-making to school administrators who sought to accommodate the largest cultural group in Milwaukee. This case study of the Milwaukee Public Schools’ German Language Program reveals how school policies prioritized a multilingual approach to Americanization. The paper is structured in three sections, examining the evolution of language policy, the political implications of the Bennett Law, and the post-Bennett landscape of language education, ultimately demonstrating the interplay between consolidation and cultural inclusivity.
Since the 1960s, the concept of civil religion has informed a great number of scholarly works exploring the relationship between religion and nationalism in the west — and beyond. It is therefore not surprising that the concept also informed seminal works on Buddhism and politics in Thailand. In recent years, however, the concept appears to have fallen out of fashion within Thai Studies and perhaps Southeast Asian Studies more broadly. This article surveys and critically discusses the widely diverging and confusing ways in which the concept of civil religion has been used in the study of Thai history and politics. It then seeks to demonstrate the continued relevance and analytical utility of civil religion, understood as a particular kind of nationalism, according to which the state should accommodate or actively encourage and support religious pluralism by developing ideological and institutional links with multiple religious communities. In Thailand, the dominant form of civil-religious nationalism is ‘cosmopolitan royalism’, which positions the king as the leading patron and protector of religions (plural). The final section of the article illustrates how this conception of civil religion might inform both the study of Thai intellectual history and the study of contemporary political contestation.
The making of the Passeio Público, Lisbon’s first public garden, is filled with contradictions, advances and setbacks. By looking at the long-term history of this green infrastructure, from its inception in 1764 until the inauguration of the boulevard built on its footprint in 1886, and considering the various technical-scientific, artistic, economic, social and political factors, this article demonstrates that the so-called public garden of the ancién régime was in fact made by the Liberals. Political issues and the Liberals’ narration of events were primarily responsible for the disappearance of the Passeio Público.
This study aims to investigate the relationship between post-traumatic stress disorder (PTSD) and job-related stress among nurses working in both central and district areas of Adıyaman following the earthquake. Additionally, we assess potential risk factors influencing both PTSD and job-related stress.
Methods
This cross-sectional study involved 332 nurses. The study considered several independent variables, including age, gender, marital status, place of residence, experience of family loss due to the earthquake, and workplace location. The dependent variables for the study were identified as post-traumatic stress disorder and job stress.
Results
Of the nurses surveyed, 69% showed symptoms of post-traumatic stress disorder.
Notably, higher job stress scale scores were identified among women (P = 0.028), married individuals (P = 0.005), those with children (P < 0.001), those who were in Adıyaman during the earthquake (P < 0.001), and those who experienced family loss due to the earthquake (P < 0.001). Furthermore, a significant positive correlation was observed between PTSD scores and job stress scores (r = 0.599; P < 0.001).
Conclusions
Given the bidirectional impact of PTSD and job stress, prompt and comprehensive interventions are essential for safeguarding nurses’ mental health and professional capacity following major events. These interventions should also consider other risk factors, such as female gender or experiencing a family loss.
The interaction between elastic structures and fluid interfaces, known as ‘hydroelastic’ problems, presents unique challenges to classical frameworks established for rigid spheres and liquid droplets. In this work, we experimentally demonstrate an intriguing phenomenon where ultrasoft hydrogel spheres rebound from a water surface at high impact speeds, even when their density exceeds that of water. We further propose a theoretical force-balance model, incorporating energy redistribution and potential flow theory, to predict the critical impact speed for the transition from sinking to rebounding, as well as the temporal evolution of both spreading diameter and cavity expansion. Our findings extend the classical Weber- and Bond-number-dominated paradigms for rigid spheres and liquid droplets, demonstrating that hydrogel dynamics is controlled by a modified elastocapillary Mach number, with rebound achievable even for hydrophilic spheres. These findings improve the understanding of soft-impact hydrodynamics and offer design principles for applications in biomimetic robotics and energy-absorbing materials.
A new form of human–machine collaborative capabilities has been called to complement traditional capabilities to ensure higher but more responsible performance. We reviewed the extant literature on leadership in the artificial intelligence context to identify the leaders’ essential artificial intelligence-driven capabilities and synthesize the systematic review findings into an integrated conceptual framework to highlight how artificial intelligence-driven organizations could lead more responsibly. We conducted the systematic review and thematic analysis based on 37 papers identified from Emerald Insight, EBSCOhost Business Source Complete, and ScienceDirect databases. We found organizational leaders require technical, adaptive, and transformational capabilities to lead in an artificial intelligence-driven disruptive organizational environment. Our findings contribute to dynamic managerial capability and responsible leadership for performance theories by showing how these three uncovered capabilities enable organizational leaders to deploy dynamic managerial capabilities – sensing, seizing and reconfiguring more responsibly.
This article examines the legal framework for offshore CO2 sequestration in South Korea, paying particular attention to how to ensure the protection of the marine environment from CO2 sequestration in sub-seabed geological formations. It analyses the relevant international regulatory framework, including the 1982 United Nations Convention on the Law of the Sea, the 1972 London Convention and the 1996 London Protocol. It then examines the Korean national legal framework relating to offshore CO2 sequestration. In the absence of detailed regulations on the process of CO2 sequestration in sub-seabed geological formations in South Korea, the article suggests detailed regulations regarding site selection, assessment of potential risks, monitoring and long-term liability to ensure environmental safety and security from offshore CO2 sequestration, which should comply with the 1996 Protocol and relevant guidelines. The development of detailed Korean national regulations ensuring compliance with international rules and standards could serve as best practices driving offshore CCS in the Asia-Pacific region.
This article examines the everyday experiences of the Egyptian minority in Milan, Italy, focusing on challenges arising from the lack of formal recognition for their religious affiliations—Islam and Coptic Orthodoxy—which are central to their ethnic identity. Drawing on Talal Asad’s notion of recognition, Edward Said’s critique of Orientalism, and Nelson Maldonado-Torres’ coloniality framework, it critiques how European policies conflate secularization with security, marginalizing non-European communities. Italy’s legal system highlights this tension: while de jure constitutional protections guarantee religious freedom, de facto bureaucratic and political barriers exclude minority faiths from equal standing. Egyptian migrants must navigate this imbalance, where theoretical rights rarely translate into practical access, forcing them to continually adapt their religious and ethnic identities in a marginalizing society. The article shows how religious invisibility sustains marginalization, contrasting Europe’s multicultural ideals with exclusionary practices. It reveals how colonial legacies shape migrant experiences and restrict rights.
We investigate the dynamics of a pair of rigid rotating helices in a viscous fluid, as a model for bacterial flagellar bundle and a prototype of microfluidic pumps. Combining experiments with hydrodynamic modelling, we examine how spacing and phase difference between the two helices affect their torque, flow field and fluid transport capacity at low Reynolds numbers. Hydrodynamic coupling reduces the torque when the helices rotate in phase at constant angular speed, but increases the torque when they rotate out of phase. We identify a critical phase difference, at which the hydrodynamic coupling vanishes despite the close spacing between the helices. A simple model, based on the flow characteristics and positioning of a single helix, is constructed, which quantitatively predicts the torque of the helical pair in both unbounded and confined systems. Finally, we show the influence of spacing and phase difference on the axial flux and the pump efficiency of the helices. Our findings shed light on the function of bacterial flagella and provide design principles for efficient low-Reynolds-number pumps.
This study explored mental workload recognition methods for carrier-based aircraft pilots utilising multiple sensor physiological signal fusion and portable devices. A simulation carrier-based aircraft flight experiment was designed, and subjective mental workload scores and electroencephalogram (EEG) and photoplethysmogram (PPG) signals from six pilot cadets were collected using NASA Task Load Index (NASA-TLX) and portable devices. The subjective scores of the pilots in three flight phases were used to label the data into three mental workload levels. Features from the physiological signals were extracted, and the interrelations between mental workload and physiological indicators were evaluated. Machine learning and deep learning algorithms were used to classify the pilots’ mental workload. The performances of the single-modal method and multimodal fusion methods were investigated. The results showed that the multimodal fusion methods outperformed the single-modal methods, achieving higher accuracy, precision, recall and F1 score. Among all the classifiers, the random forest classifier with feature-level fusion obtained the best results, with an accuracy of 97.69%, precision of 98.08%, recall of 96.98% and F1 score of 97.44%. The findings of this study demonstrate the effectiveness and feasibility of the proposed method, offering insights into mental workload management and the enhancement of flight safety for carrier-based aircraft pilots.
Distinguishing early domesticates from their wild progenitors presents a significant obstacle for understanding human-mediated effects in the past. The origin of dogs is particularly controversial because potential early dog remains often lack corroborating evidence that can provide secure links between proposed dog remains and human activity. The Tumat Puppies, two permafrost-preserved Late Pleistocene canids, have been hypothesized to have been littermates and early domesticates due to a physical association with putatively butchered mammoth bones. Through a combination of osteometry, stable isotope analysis, plant macrofossil analysis, and genomic and metagenomic analyses, this study exploits the unique properties of the naturally mummified Tumat Puppies to examine their familial relationship and to determine whether dietary information links them to human activities. The multifaceted analysis reveals that the 14,965–14,046 cal yr BP Tumat Puppies were littermates who inhabited a dry and relatively mild environment with heterogeneous vegetation and consumed a diverse diet, including woolly rhinoceros in their final days. However, because there is no evidence of mammoth consumption, these data do not establish a link between the canids and ancient humans.
Do populist governments bend their economic policies to the preferences of bondholders? Populist governments should be a “least likely” case for the market discipline hypothesis. Populist parties typically run on platforms that scapegoat wealthy elites as “enemies of the people” and hence should be more resistant to changing policy positions in the face of market pressure, given their reluctance to alienate their base. Employing most-different case studies of the Five Star Movement/Lega coalition in Italy and Viktor Orbán’s government in Hungary, we find that populists do bend to market pressure but that this “disciplining effect” does not stem primarily from foreign investors. Rather, it was the inaction of domestic investors in bond auctions that caused these governments to reverse course on headline economic policies. Because domestic investors served as both governments’ “buyers of last resort,” they needed to maintain their favor amidst foreign capital flight.
Housing scarcity is a widespread social and economic problem. Prior studies have attributed this scarcity to local control over land use, which has been seen as making policy makers more responsive to small electorates. Challenging this argument, we suggest that smaller jurisdictions have stronger incentives and greater capacity to raise tax revenue by building housing. Therefore, expanding the electorate that policy makers are responsive to could lead to a more restrictive housing policy. To explore this question empirically, we study a reform that consolidated some Danish municipalities, increasing the size of their jurisdiction. Using a difference-in-differences design, we find that consolidated municipalities issue fewer permits and complete less housing than smaller jurisdictions. Our study thus shows that politicians permitted more housing when they were accountable to a smaller electorate. This upends conventional wisdom and suggests that local control need not be at odds with more liberal land use policy.
The investigation of shock/blast wave diffraction over various objects has garnered significant attention in recent decades on account of the catastrophic changes that these waves inflict on the environment. Equally important flow phenomena can occur when the moving expansion waves diffract over bodies, which has been hardly investigated. To investigate the effect of expansion wave diffraction over different bodies, we conducted shock tube experiments and numerical simulations to visualise the intricate wave interactions that occur during this process. The current investigation focuses on the phenomenon of expansion wave diffraction across three distinct diffracting configurations, namely the bluff, wedge and ogive bodies. The diffraction phenomenon is subsequently investigated under varying expansion wave strengths through the control of the initial diaphragm rupture pressure ratios. The shock waves generated by the expansion wave diffraction in the driver side of the shock tube, which was initially identified in numerical simulations by Mahomed & Skews (2014 J. Fluid Mech., vol. 757, pp. 649–664), have been visualised in the experiments. Interesting flow features, such as unsteady shock generation, transition, and symmetric/asymmetric vortex breakdown, have been observed in these expansion flows. An in-depth analysis of such intricate flow features resulting from expansion wave diffraction is performed and characterised in the current study.
Mixing-induced reactions play an important role in a wide range of porous media processes. Recent advances have shown that fluid flow through porous media leads to chaotic advection at the pore scale. However, how this impacts Darcy-scale reaction rates is unknown. Here, we measure the reaction rates in steady mixing fronts using a chemiluminescence reaction in index-matched three-dimensional porous media. We consider two common mixing scenarios for reacting species, flowing either in parallel in a uniform flow or towards each other in a converging flow. We study the reactive properties of these fronts for a range of Péclet numbers. In both scenarios, we find that the reaction rates significantly depart from the prediction of hydrodynamic dispersion models, which obey different scaling laws. We attribute this departure to incomplete mixing effects at the pore scale, and propose a mechanistic model describing the pore-scale deformations of the front triggered by chaotic advection and their impact on the reaction kinetics. The model shows good agreement with the effective Darcy-scale reaction kinetics observed in both uniform and converging flows, opening new perspectives for upscaling reactive transport in porous media.
