On July 11, 1924, the Lincoln reached Angel Island, the desolate and remote location of the infamous immigration station in California. Aboard the ship were nine Chinese wives, hopeful that they would soon reunite with their spouses who had preceded them to the United States. Until then, despite harsh immigration laws, many Chinese women had been admitted to the country because they were married to noncitizen merchants or to American citizens. Building on coverture principles that a man’s care and comfort were so important that his wife’s status should follow his, Chinese husbands had often argued successfully that their right to reunite with their families took precedence over existing immigration laws, which excluded Chinese immigrants because of their race. It was these laws, they contended, that had forced many Chinese migrants into transnational marriages in the first place. Despite these precedents, the immigration officers who inspected the women on the Lincoln rejected them all, regardless of their age, education, and class.
Managers confronting important strategic decisions often receive diagnostic information sequentially over time. As new information becomes available, they may need to update their understanding of the situation and possibly revise their preferences. During a decision, as a preference develops for one alternative course of action, a nonconscious goal of maintaining consistency between that preference, however tentative, and the new information can lead to an interpretation of that information so as to support the current preference. This tendency to bias or distort information to support the currently preferred option can in turn lead to even greater confidence in that leading option, despite the increase in confidence being unwarranted by the information itself. The result of such a biased decision process can be overconfidence in the chosen course of action. To show this, in the current work, experienced managers engaged in a realistic business decision task with their levels of information distortion and confidence tracked throughout the decision. Over the course of the decision, confidence in the leading action increased as a function of distortion. The results confirmed that distortion-driven confidence can develop even when decision makers have no prior preference for one of the outcomes.
The effect of a smooth surface hump on laminar–turbulent transition over a swept wing is investigated using direct numerical simulation (DNS), and results are compared with wind tunnel measurements. When the amplitude of incoming crossflow (CF) perturbation is relatively low, transition in the reference (without hump) case occurs near $53\,\%$ chord, triggered by the breakdown of type I secondary instability. Under the same conditions, no transition is observed in the hump case within the DNS domain, which extends to $69\,\%$ chord. The analysis reveals a reversal in the CF velocity component downstream of the hump’s apex. Within this region, the structure and orientation of CF perturbations are linearly altered, particularly near the wall. These perturbations gradually recover their original state further downstream. During this recovery phase, the lift-up mechanism is weakened, reducing linear production, which stabilises the stationary CF perturbations and weakens spanwise gradients. Consequently, the neutral point of high-frequency secondary CF instability modes shifts downstream relative to the reference case, leading to laminar–turbulent transition delay in the presence of the surface hump. In contrast, when the amplitude of the incoming CF perturbation is relatively high, a pair of stationary counter-rotating vortices forms downstream of the hump. These vortices locally deform the boundary layer and generate regions of elevated spanwise shear. The growth of secondary instabilities in these high-shear regions leads to a rapid advancement of transition towards the hump, in agreement with experimental observations.
This project investigates how skin tone and gender of Black political candidates work together to influence White Americans’ evaluations. Drawing on the colorism literature and group position theory, I develop a theoretical framework anticipating how the skin tone of Black candidates may influence White voters’ perceptions. Two survey experiments were conducted on nationally representative samples. Both studies highlight that skin tone is meaningful to White voters’ evaluations, but in nuanced ways based on gender. Specifically, the darker-skinned Black female candidate is evaluated more positively than her lighter-skinned female and darker-skinned male counterpart across multiple domains, including vote choice and expected job performance. These findings suggest that gender can attenuate the negative stereotypes typically associated with darker skin tone in some contexts. These findings underscore the importance of theorizing about race as a multidimensional construct, with implications for understanding hierarchy, intergroup relations, and electoral politics in a diversifying American racial landscape.
Modern gravestones have been a common sight in European towns and cities for just over three hundred years. They provide a wealth of information beyond simply names and dates, and can teach us a great deal about the time and place in which they were erected and the people who built them. I have been recording and conserving gravestones for fifteen years, and here I present some of the techniques, sources, and hard-learned lessons of using gravestones as archival material that will enable you to see your local graveyard in a whole new light.
On July 4, 1895, U.S. flags fluttered alongside red Chinese lanterns outside 753 Clay Street, the newly claimed San Francisco headquarters of the Native Sons of the Golden State (NSGS).1 Inside, NSGS president Chun Dick rose to speak. Standing at five feet two inches with short-cropped black hair, he shared that at least fifty men in NSGS were birthright citizens and ready to vote, and that more Chinese American voters would follow.2 Chun Dick, members of the Chinese community in attendance, their guests, and journalists in the room reflected a new political reality: Chinese American children, born in the United States, were coming of age and claiming a place in U.S. politics. Chinese immigrants constituted the largest racial minority in the state, and while many were ineligible to vote, their children who could were organizing to do so. Therefore, this moment on July 4 in San Francisco marked a turning point.
This article uses Israel’s prolonged effort to join the Union of European Football Associations (UEFA) to examine how post-war Europe negotiated the institutional and symbolic boundaries of continental belonging. Drawing on FIFA archives, diplomatic correspondence, and Hebrew-language media, it traces how football became a stage where affiliation was both asserted and tested by those seeking entry and those empowered to grant it. UEFA’s rejection of Israel was framed in geographic terms, yet its eventual inclusion followed neither territorial logic nor legal reform, but a quiet politics of accommodation: informal gestures, deferred decisions and precedent-setting exceptions. Within Israel, the campaign served as a proxy for broader debates over the country’s geopolitical direction between Asia and Europe. By linking institutional deliberations to domestic discourse, the article argues that Europe’s post-war map took shape less through design than through the incremental negotiation of memory, strategy and symbolic positioning.
Young adults (19–24 years) commonly experience elevated rates of sleep disturbance, anxiety, and cognitive stress yet often underutilise formal mental-health services. Music therapy, binaural beats, and related auditory entrainment techniques offer accessible, non-pharmacological approaches that may enhance emotional regulation, cognition, and physiological stability.
Objective:
To systematically review interventional clinical trials published over the past decade evaluating music- and rhythm-based auditory interventions for mental-health and cognitive outcomes in young adults.
Methods:
A systematic search of PubMed/MEDLINE and PsycINFO (01 January 2015 – 01 January 2025) was conducted using the terms (music therapy OR binaural beats OR auditory entrainment) AND (mental health OR neurorehabilitation OR cognition OR anxiety OR depression). After screening 122 abstracts, 10 trials met inclusion criteria. Effect sizes (Cohen’s d) and 95% confidence intervals were extracted or estimated. Risk of bias was assessed using the Cochrane RoB-2 tool. The review protocol was registered in PROSPERO (CRD420251178490).
Results:
Interventions included bedtime music therapy, audiovisual stimulation, and binaural-beat exposure across laboratory, clinical, and rehabilitation settings. Most studies demonstrated significant or moderate improvements in at least one domain: anxiety reduction, stress physiology, mood regulation, sleep quality or cognitive performance (standardised mean differences 0.3–0.6).
Conclusions:
Evidence suggests that music-based and binaural-beat interventions can beneficially modulate sleep, anxiety, and cognitive processes in young adults. However, heterogeneity in design and small sample sizes limit the certainty of findings. Future adequately powered randomised controlled trials should address transdiagnostic mechanisms and long-term efficacy.
For efficient wind farm management and optimized power generation under adverse weather conditions, understanding the causal meteorological drivers is essential. In this paper, we investigate the temporal causal influences of wind speed-related meteorological processes within a wind farm using the Heterogeneous Graphical Granger model (HMML). HMML is applied to synthetically generated wind power production data from Eastern Austria. To assess the plausibility of the identified causal processes, we compare the results with those obtained using the state-of-the-art LiNGAM method. Both methods are applied and evaluated across six different scenarios, each defined by distinct hydrological periods. The scenarios are defined by a set of time intervals characterized by either low/high extreme wind speeds or moderate wind speeds. We applied both methods across these scenarios and conducted causal reasoning to identify potential causes of extreme wind speeds within the wind farm. The sets of causal parameters obtained using HMML were found to be more realistic than those derived from LiNGAM. Combining the knowledge of causal variables affecting wind speed at the turbine hub, identified by HMML in each scenario, with weather forecasts can offer practical guidance for wind farm operators. Specifically, this knowledge can support more informed planning regarding when wind turbines should or should not be generating energy. For instance, the strong Granger-causal linkage identified between wind speed and temperature can inform curtailment strategies. In scenarios where rising temperatures are predictive of declining wind speeds, operators may preemptively adjust turbine output or schedule maintenance to optimize efficiency and reduce wear. Moreover, such predictive insights can feed into energy market models, where anticipated curtailment due to meteorological dependencies affects both generation forecasts and pricing strategies. By integrating these causal relationships into operational planning, the proposed tool offers a pathway toward more adaptive and economically efficient wind energy management.
This article investigates the vocabulary of astral sciences preserved in the Huihui Guan Zazi (回回館雜字), a Persian–Chinese glossary commissioned by the Ming imperial court in the early fifteenth century. Situating the text within the broader context of Mongol and post-Mongol Eurasian intellectual exchange, this article analyzes the glossary’s technical astronomy and astrology terms with attention to their precision, methods of translation, and the direction of knowledge transmission. The findings suggest a high level of conceptual translation and a bidirectional flow of knowledge, pointing to a multilingual environment sustained by close engagement with scientific texts under Mongol rule and retained in the early Ming. By contrast, supplementary materials within the glossary produced in the late sixteenth century reveal the erosion of this intellectual vitality, signaling the decline of Persianate influence within the Ming imperial bureaucracy.
Used for common daily tasks, ground stone tools were vital to the functioning of pre-Columbian Maya households. Yet as an artifact class, ground stone has historically received little archaeological attention. Throughout the Eastern Maya Lowlands, ground stone tools were made of a variety of materials although granite was a preferred raw material. Granite is geographically restricted to three plutons, making it a prime candidate for geochemical sourcing studies. Fueled in part by advances in compositional techniques, as well as by new finds from traditional field archaeology, interest in the topic has blossomed over the past decade. This Compact Section explores many facets of the pre-Columbian Maya granite ground stone economy, from raw material acquisition to end of life discard, with the goal of disseminating the work of ongoing research projects. Ultimately, we aim to encourage more research on ground stone tools in general and granite in particular in Maya archaeology. Like other sister categories of artifacts, ground stone deserves requisite research attention to answer questions about where and how raw materials were acquired, how these objects were crafted, what distribution networks looked like, how they signify broader social meanings, and beyond.
Scholarship on overseas Chinese and modern Chinese diplomacy often centers on nationally recognized leaders and officials with prominent global roles. However, a fuller understanding of the diaspora requires examining lesser-known diplomats and local leaders who often had a greater impact on their communities than distant official policies. The transnational life and evolving identity of Yü Shouzhi (1907–1999) – a grassroots Chinese diplomat, community organizer, and small business owner in Mexico – exemplifies this dynamic. Initially trained and appointed by the Chinese Nationalist government, Yü’s diplomatic work extended beyond official channels to foster transethnic, transnational, and intergenerational networks within the Chinese-Mexican community. His transition from formal diplomacy to community leadership and commerce reflected how individual migrants successfully navigated transnational and national politics, community relationships, kinship, and transethnic relations and gained social power. In the process, Yü adjusted his sense of belonging and developed diasporic nationalism, transforming from a representative of the Nationalist government to a deeply rooted Chinese-Mexican community member. This article argues that Yü’s ability to adapt his role as a Chinese diplomat and cultivate a Chinese-Mexican identity was shaped by the interplay of formal state affiliations, grassroots networks, transnational and cross-ethnic relationships, and his personal initiative.
In 1994, Shor introduced his famous quantum algorithm to factor integers and compute discrete logarithms in polynomial time. In 2023, Regev proposed a multidimensional version of Shor’s algorithm that requires far fewer quantum gates. His algorithm relies on a number-theoretic conjecture on the elements in $(\mathbb {Z}/N\mathbb {Z})^{\times }$ that can be written as short products of very small prime numbers. We prove a version of this conjecture using tools from analytic number theory such as zero-density estimates. As a result, we obtain an unconditional proof of correctness of this improved quantum algorithm and of subsequent variants.
Vitriolic disputes over trans identity and decolonisation have made university campuses into the battlegrounds of the culture wars. Yet the connections between these controversies and the epistemic function of the academy remain underexamined. In this article, I argue that the structures of oppression and privilege that activists seek to dismantle are sustained by the disciplinarity of the academy. Inspired by Sylvia Wynter’s radical critique of Western humanism, I show how the entrenched division between the sciences and the humanities upholds a biocentric conception of truth that underwrites “Man,” the mode of life that colonises the concept of the human. The article outlines Wynter’s theory of sociogenesis to interrogate the role of the disciplines in repressing awareness of the sociocultural constitution of modes of life, arguing that this denial of discursive construction sustains the hegemony of Man while foreclosing trans liberation. What follows, I suggest, is that the academy’s culture wars crises cannot be resolved through diversity policies. Instead, I call for a transformation of disciplinarity that untethers the academy from the epistemological commitments of Man. Only by eschewing positivism and universalism can institutions of higher education break with the coloniality of gender and contribute to reimagining the human.
When Congress debated the wording of the Fourteenth Amendment, Chinese immigration was not at the forefront of legislators’ minds. They were primarily focused on granting citizenship to newly emancipated Black people while continuing to deny it to Native people living outside of America’s jurisdiction. Their ultimate choice of words reflected these desires. The first sentence of the amendment proclaimed, “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”1
