This article revisits the development of the field of British queer history to argue that the division that began in the later 1970s—between works focused on the periods before and after the late nineteenth century—has obscured underlying methodological unities that developed within the scholarship since the 1990s. The failure to emphasize common cultural history methodologies that have been the hallmark of the best works analyzing same-sex desire and transing gender for the period from the late seventeenth century onward is due in part to the separating off of histories of same-sex desire between women from those studies focused on men. This article argues that a Foucauldian understanding of power, the liberal public sphere, and liberal political systems, all dating from the late seventeenth century, provide a unified context for the formulating and unraveling of a wide range of self-understandings in relation to gender and sexual desires. What explains the developments of the late nineteenth century stems from the first such self-understandings being formulated for the requirements of a rights-bearing subject within a liberal political system. This approach highlights the ethical component of public political identities, and the consequences of this for British queer history going forward.
This study demonstrates a non-monotonic relation between pool temperature and thawing time for the ice-core thawing problem in a water pool. Numerical simulations reveal that this non-monotonicity arises from competing flow mechanisms from the non-Oberbeck–Boussinesq effect driven by the density-temperature anomaly at ${\sim}4\,^\circ \text{C}$ of water. The sides come from the anomaly-triggered chaotic flow and the normal natural convection stabilised by the buoyancy force. During the thawing process, the flow in the pool experiences a transient stable, an oscillatory, a transitional and the finally chaotic state over time. The pool size modulates the competition between chaotic flow and natural convection through the Rayleigh numbers with a critical value $\varLambda _{c}$. Within the considerations of this study, a smaller pool size leads to a more non-monotonic appearance. The competition governs both the extreme points in thawing time and the extent of the non-monotonic effect, thereby enabling accurate control over thawing kinetics. These insights clarify how the non-Oberbeck–Boussinesq effects from density and viscosity govern the ice-core thawing dynamics and pave the way for advanced controlled-thawing technologies in applications such as cryopreservation and organ resuscitation.
Microaggressions have been a topic of significant debate in the psychological and social sciences. Despite an extensive body of empirical evidence, numerous misconceptions persist. This paper deconstructs common misconceptions surrounding microaggressions and addresses their origins, underlying biases, and empirical refutations. We explain the mechanisms that cause and maintain microaggressions through a CBT lens. We examine widely propagated misconceptions, including claims that microaggressions lack scientific validity, are too subjective to measure, and are not indicative of racism or other forms of prejudice. Drawing on the substantial literature base, including validated psychometric scales, experimental studies, and cross-cultural analyses, we demonstrate that microaggressions are not only real but also have significant psychological and social consequences. Empirical evidence links microaggressions to outcomes such as depression, anxiety, and lower self-esteem, reinforcing their relevance in clinical, educational, and workplace settings. CBT models provide a useful lens for understanding how individuals navigate the psychological complexities associated with microaggressive behaviours, helping explain why some people resist acknowledging microaggressions and their consequences. Lastly, we highlight the importance of education for reducing the prevalence of microaggressions and mitigating their harmful effects. Our goal is to provide clinicians with correct information so that they may skilfully and empathetically help clients experiencing microaggressions, and to no longer accept microaggressions as a harmless, misunderstood, or dismissed phenomenon. By debunking these misconceptions, this work contributes to a more scientifically grounded understanding of microaggressions, emphasizing the necessity of continued research and intervention efforts to address the impact of discrimination in society.
Key learning aims
(1) Build awareness around the various misconceptions associated with microaggressions.
(2) Knowledge of why these misconceptions exist, where they came from, and why they are important to consider and refute.
(3) Refuting misconceptions with scientific explanations and evidence.
(4) Understand how CBT clinicians can better prevent and respond to microaggressions.
Urban surfaces play a central role in mediating microclimatic conditions, influencing not only human thermal comfort but also the viability of urban biodiversity. This study explores porous, geometry-driven design strategies for urban surfaces and evaluates their thermal performance as a preliminary step toward future building envelope systems that accommodate more-than-human inhabitants. With the nest microclimate of cavity-nesting wild bees as the target condition, three experimental setups were conducted using 3D-printed (3DP) porous nesting aids fabricated via Fused Deposition Modeling (FDM) from biobased polymers and compared to a conventional reed-based nesting aid. The samples were installed on a southeast-facing façade in Stuttgart, Germany, and internal nesting tube temperatures were monitored during August 2024. All 3DP samples maintained internal temperatures up to 1.6 K cooler on average than the conventional nesting aid and, critically, none exceeded the 40 °C threshold associated with high larval mortality. In contrast, the conventional nesting aid reached peak temperatures of 41.6 °C for over eight cumulative hours. While geometric and material variations produced only modest thermal differences among the 3DP configurations, the results demonstrate that porous geometries can reduce extreme heat exposure in sun-exposed urban contexts. These findings support further development of thermally responsive urban surface systems that integrate ecological performance criteria into building design.
Psychological research has long centered around questionnaire assessments, but now digital devices, especially smartphones, enable the collection of real-world behavioral data through mobile sensing. While this data collection method offers unique opportunities, it also introduces new methodological challenges, as mobile-sensing data are highly complex and high in dimensionality (i.e., timestamped events with millisecond resolution), requiring advanced preprocessing to derive psychologically meaningful variables. This article highlights these challenges by reviewing the current state of data preprocessing based on app usage logs from smartphones. Afterward, it presents three preprocessing cases that vary in complexity across the dimensions of data enrichment—which involves adding context to raw data by integrating information from external and internal sources (including ecological momentary assessments)—and data aggregation—which entails summarizing data in different ways, from basic descriptive statistics to sophisticated machine-learning models. For each case, potential pitfalls are identified, and extensions are discussed to refine our preprocessing pipelines and accommodate different data types and research questions. By outlining these preprocessing strategies, this manuscript demonstrates the rich potential of mobile-sensing data for extracting nuanced behavioral variables beyond simple person-level summaries and aims to inspire the development of more advanced research questions based on sensing data.
This study investigated the population structure of predatory bugs belonging to the genus Orius (Hemiptera: Anthocoridae), with a specific focus on O. strigicollis and O. sauteri. These insects are promising candidates for biological pest control in agriculture. O. strigicollis has limited distribution in the warmer coastal areas of the western regions of Japan, whereas O. sauteri is more widely distributed. We conducted genetic analyses using microsatellite markers and an isolation-by-distance analysis to understand the potential differences between these two species. We studied 494 individuals from 9 populations in the Chubu region of Japan, where they are sympatrically distributed. A significant positive correlation was observed between geographical distance and genetic differentiation (fixation indices; FST) in O. strigicollis, suggesting limited gene flow between populations. Contrastingly, no significant correlation was observed in O. sauteri, indicating a higher gene flow and larger population size. Thus, these results contribute to the development of biological control strategies for these species.
In the 1790s, hundreds of refugees arrived in Philadelphia from revolutionary Saint-Domingue. Though it is well known that the Alien Acts were promulgated at least in part in reaction to the large French presence on US soil and the threat of war with France, other barriers to entry and to remain on US soil are not often connected to the arrival and presence of French refugees. Using records of the Philadelphia courts, prison, and almshouse, this article situates the French refugee experience within the early United States’ broader kaleidoscope of restrictions on mobility, assistance, and rights to remain. For the French Black population, their race and class rendered them especially vulnerable to forms of mobility control focused on criminals and the mobile poor. Though the French were not ultimately deported for their political activities, a small number of French Black refugees convicted of theft were set on the move once again.
This study investigates the nonlinear dynamics and control strategies for a Cessna-182 unmanned aerial vehicle (UAV). The longitudinal and lateral dynamic models were derived using aerodynamic analysis conducted in ANSYS Fluent. Various control methodologies, including PID (proportional, integral, derivative) tuning with genetic algorithm (GA), root locus (RL), MATLAB tuned (MT), Ziegler Nichols (ZN), the model reference adaptive controller (MRAC), linear quadratic regulator (LQR) and linear quadratic Gaussian (LQG), were implemented and compared through simulations. Due to the inadequacy of PID control under variable environmental and noise conditions, LQR and LQG controllers, including the full state-space model required for real-time applications, are simulated for both longitudinal and lateral motions in addition to the PID controller. Although the LQR controller has acceptable simulation results for noiseless conditions, the superiority and stable structure of the LQG controller under noise and disturbance effects are highlighted. The results, including noise Dryden turbulence effects, highlight the advantages of proposed MRAC and LQG for robust stability and precise flight performance. Experimental flight tests validate the theoretical findings, demonstrating the practical viability of the proposed control approaches. The results obtained for the Cessna-182 mini-UAV will be effective for future researchers in terms of obtaining UAV dynamics and also evaluating different control strategies of the UAV.
Associations of cerebrospinal fluid biomarkers with sleep, functionality and the MDS-UPDRS in dementia with Lewy bodies (DLB) and late-onset Alzheimer’s disease (AD) help elucidate their pathophysiological underpinnings.
Methods:
Consecutive outpatients with DLB and AD were matched by sex, cognitive scores and dementia stage, along with cognitively healthy controls matched by age and sex to investigate associations of cerebrospinal fluid amyloid-β (Aβ42,Aβ40,Aβ38), tau, phospho-tauThr181, ubiquitin, α-synuclein and neurofilament light (NfL) with sleep duration, Schwab & England scale and MDS-UPDRS, adjusted for sex, age and APOE-ϵ4 alleles.
Results:
Patients with DLB (APOE-ϵ4+:n=11, 76.64±9.0years; APOE-ϵ4-:n=16, 79.75±9.0years) were paired with patients with AD (APOE-ϵ4+:n=12, 80.17±5.7years; APOE-ϵ4-:n=15, 81.67±5.9years) and controls (APOE-ϵ4+:n=4, 82.00±6.4years; APOE-ϵ4-:n=23, 77.87±9.0years); two-thirds were women. APOE-ϵ4 carriers with dementia had more amyloidosis, higher phospho-tauThr181/Aβ42 and α-synuclein/Aβ42. In DLB, APOE-ϵ4 non-carriers had lower Schwab & England scores and higher MDS-UPDRS-I&II scores, lower tau/phospho-tauThr181 and higher ubiquitin and NfL than APOE-ϵ4 carriers. In controls, APOE-ϵ4 non-carriers had lower Aβ42 and Aβ42/Aβ38, higher phospho-tauThr181/Aβ42 and α-synuclein/Aβ42 than APOE-ϵ4 carriers. In DLB, sleep duration was associated with Aβ38 and α-synuclein and inversely associated with tau/phospho-tauThr181 and tau/ubiquitin; Schwab & England scores were associated with tau/ubiquitin and inversely associated with tau/phospho-tauThr181; MDS-UPDRS-I&II was associated with Aβ42/Aβ38; MDS-UPDRS-III was associated with tau/phospho-tauThr181; MDS-UPDRS-V ON was associated with Aβ42 and Aβ42/Aβ40, and MDS-UPDRS-V OFF was associated with Aβ42, Aβ42/Aβ40 and Aβ42/Aβ38. In AD, MDS-UPDRS-III was associated with ubiquitin.
Conclusion:
Biomarker ratios were superior to isolated biomarkers in associations with motor and non-motor experiences in DLB, though not so prominently in AD due to less motor impairment.
Applying teat dips to cows’ teats before and after milking (pre- and post-dipping) are important methods for preventing mastitis. Given the proven effectiveness of ozonated water for eliminating bacterial colonies, this study aimed to evaluate the effectiveness of ozonated water in preventing mastitis in pre- and post-dipping of dairy cows. Fifty-eight cows were selected based on negative black-bottom cup test results and the California mastitis test (CMT), and randomly allocated into two groups: the control group (CG, n = 23) where pre- and post-dipping were done with a commercial hydrogen peroxide product, and the ozone group (OG3, n = 35) where ozonated water at a concentration of 2 µg/ml was used, prepared immediately before use with an ozone generator. Samples were collected at four timepoints: M0 (pre), M1 (72 h), M2 (7 d) and M3 (14 d). Somatic cell count, CMT, pH, milk composition, and microbiological identification were analysed. The black-bottom cup test and physical evaluation of the udder were performed daily before milking. All milk composition variables were similar in both groups. SCC remained within normal ranges for both groups at all time points as per the guidelines of the Brazilian Ministry of Agriculture, Livestock and Food Supply. Microbiological cultures revealed similar pathogens across time points with the same growth dynamics. The study demonstrated that the use of ozonated water was as effective as the commercial product used in pre- and post-dipping for hygiene and prevention of mastitis in dairy cows, potentially serving as a viable alternative with lower environmental contamination, especially on organic dairy farms. Further studies comparing different concentrations and evaluations against other sanitizers are necessary.
In recent years, there has been a growing body of scholarship that distinguishes post-colonial and post-imperial migrations from other forms of migration. However, because this literature largely excludes non-European cases, it remains predominantly Eurocentric. This review article seeks to demonstrate how these studies can be further enriched by incorporating Ottoman migrations (muhacir) as a distinct form of post-imperial migration. To this end, the article evaluates four recently published works on Ottoman migration: İpek’s Migration in the Imperial Territories (Memalik-i Şahanede Muhaceret), Fratantuono’s Governing Migration in the Late Ottoman Empire, Hamed-Troyansky’s Empire of Refugees, and Oktay Özel’s Katamizes In Pursuit of the Blue (Kiske Kuşunun Peşinde Katamizeler). Through a comparative analysis of these works, the article explores the potential contributions of Ottoman post-imperial migration studies to the broader literature on post-imperial migration. In particular, it addresses issues such as the role of official historiography in shaping migration histories; debates over whether migrants were framed as returnees or repatriates; the effects of different imperial structures; and the ethnic and religious composition of both host societies and migrant populations.
Clinical researchers at U.S. academic health centers are becoming more attuned to the perspectives and values of research participants, seeking to partner with them to enhance their satisfaction and improve recruitment strategies.
Methodology:
We surveyed current or recent participants on their perspectives about the return of study results. Through a multi-site consortium of academic medical centers assessing the experiences of research participants using an online satisfaction survey, we added three questions to our institution’s version of the survey to assess the value placed on return of research results (RoR) to current or recent adult participants. Survey participants were offered anonymous participation using four different recruitment mechanisms (“sites”) hosted by our institution. Most recruitment was disease-agnostic.
Results:
A total of 506 heterogeneous respondents completed the survey. Although differences were found across recruitment sites, 73% of all participants desired and 49% expected to receive their own RoR, while 61% expected to receive the study’s aggregate results. The importance of receiving their own results was especially salient for respondents from historically underserved communities, identifying as non-white, Latino/Hispanic, primarily Spanish-speaking, older or less educated. Respondents’ sex was not a significant factor in preferences for return of results.
Conclusions:
Our results indicated our research participants’ expectations and perceived value of receiving the results from studies in which they participated, especially their individual results. This study provides direct evidence of the desires of our research participant community and suggests that institutional support for the return of study results would better serve participants’ interests and expectations in future research.
This article examines how courts in a diverse and divided society navigate tensions over a polarized religious issue. The incrementalist approach that defers difficult choices about state and religion through vague compromise has been defended in polities where achieving cohesion proves difficult. This article investigates how the court grapples with incrementalist logic underlying the regulation of interfaith marriage in Indonesia. To mitigate disagreements, the Indonesian Marriage Law has left the legality of interfaith marriage ambiguous and subject to constant negotiation and compromise. This article argues that the Indonesian Constitutional Court has failed to sustain this balance, as the court increasingly leans towards the religious aspect of marriage. Indonesian experience shows the complexities of court interventions on unclear legislative agreements and contentious issues in society. The Court adopted a rigid legal interpretation based on conservative religious views, which not only undermines rights and pluralism, but intensifies tensions and complicates future negotiations.
Host–parasite coevolution resulted in parasites optimizing their life cycle to obtain the most benefit from the host’s behaviour. In passerines, for instance, some parasite groups have found means to match their egg shedding rhythms with the hours of the day when hosts are most active. In other bird groups, such as shorebirds, whose active times are not determined by day–night cycles but by other external factors such as tidal or lunar cycles, it is not yet known whether their endoparasites exhibit any predictable pattern in their egg shedding rhythms. Here we used a simple wild-caught (captive) system, to provide a first approximation of the parasite egg shedding patterns in wintering Rufous-chested dotterels (Zonibyx modestus). We collected faeces every 2 hours over 10 days until completing a 24-hour cycle, which was coupled with continuous video recordings to determine their feeding and drinking habits. Contrary to our expectation, we showed that parasite egg shedding followed a cyclic pattern, characterized by 2 peaks: one at midnight and another in the afternoon. Importantly, this shedding pattern was not related to the birds’ feeding or drinking habits. We discuss possible environmental and physiological cues that parasites might use to trigger egg production, including the potential influence of tidal cycles on our results.
Onion seed productivity, quality, and profitability in Ethiopia are constrained by declining soil fertility and inadequate fertilizer management, particularly due to a historical reliance only on blanket nitrogen-phosphorus-based recommendations for bulb production. Therefore, the study examined the impacts of NPSB fertilizer, vermicompost, and their integrated application on soil fertility, onion seed yield, and quality in Yaya-Gulele, Oromia, Ethiopia. Treatments comprised a factorial combination of four NPSB rates (0, 75, 150, 225 kg/ha) and four vermicompost rates (0, 1.25, 2.5, 3.75 t/ha), arranged in a randomized complete block design with three replications. Seed quality was evaluated under laboratory conditions using a completely randomized design with four replications. The integrated application of NPSB and vermicompost improved key soil chemical properties, prolonged vegetative growth, and enhanced seed yield and quality parameters of onions compared to sole applications and the control. The highest-performing integrated treatment increased seed yield by up to threefold relative to the control. The integration of 150 kg/ha NPSB with 3.75 t/ha vermicompost was identified as the most agronomically and economically optimal treatment, producing the highest seed yield and net returns. This first report from North Shewa shows that the synergistic integration of NPSB and vermicompost significantly increases onion seed productivity and quality by improving soil fertility. This approach offers a practical and sustainable nutrient management strategy for onion seed production systems in Ethiopia.
