Slovak national communism as a specific approach to the problem of Czech-Slovak relations gained a significant position within the Communist Party of Czechoslovakia soon after its establishment in 1921. This article analyzes the foundations of this phenomenon and the evolving attitudes of the first generation of Slovak communist intellectuals and Party functionaries. The article’s primary focus is on the Slovak communists’ views regarding the official state doctrine of a unified Czechoslovak nation, Czech-Slovak relations, and the issue of Slovak autonomy. The study highlights the significant external influences, particularly the directives of the Communist International and the pre-existing national stereotypes, that shaped the worldview and nationalist tendencies of Slovak communists.
Showcasing how understandings of social mobility encoded raciolinguistic ideologies of the ideal upwardly mobile speaker, I investigate blue- and white-collar orientation to language, race, and social mobility in the Canadian labor market. I analyze these two subject positionalities and the way bundles of skills are ‘bundled otherwise’ when ideologies of race and language are invoked as relevant to a class experience. While the acquisition of standard languages remains understood as a gateway to upward mobility, the increased commodification of language made the acquisition of standard registers of French and English a skill amongst others, on par with any other. If this shift challenges an implicit ‘linguistic’ bias embedded in emic and scientific understandings of class, raciolinguistic ideologies continue to organize worker's orientations to language and work, be it to imagine themselves as cosmopolitan workers or to defend the positions of ethnic, national, and racialized groups in the economy.

We use the Korteweg–de Vries (KdV) equation, supplemented with several forcing/friction terms, to describe the evolution of wind-driven water wave packets in shallow water. The forcing/friction terms describe wind-wave growth due to critical level instability in the air, wave decay due to laminar friction in the water at the air–water interface, wave stress in the air near the interface induced by a turbulent wind and wave decay due to a turbulent bottom boundary layer. The outcome is a modified KdV–Burgers equation that can be a stable or unstable model depending on the forcing/friction parameters. To analyse the evolution of water wave packets, we adapt the Whitham modulation theory for a slowly varying periodic wave train with an emphasis on the solitary wave train limit. The main outcome is the predicted growth and decay rates due to the forcing/friction terms. Numerical simulations using a Fourier spectral method are performed to validate the theory for various cases of initial wave amplitudes and growth and/or decay parameter ranges. The results from the modulation theory agree well with these simulations. In most cases we examined, many solitary waves are generated, suggesting the formation of a soliton gas.
The authors seek to design a lower limb exoskeleton to augment human finned swimming; however, data associated with human finned swimming previously did not exist, particularly data that characterizes the active joint torque requirements for human-scale finned swimming motion and the corresponding thrust generation. Since these data are not directly measurable nor easily computed in human subject experiments, the authors instead employed a human-scale robotic platform to characterize the relationship between joint torque, speed, power, and thrust production during flutter kick swimming, specifically at the hip joints. Among the useful insights from this study: (1) the underwater environment can be accurately modeled as a simple viscous load as seen by the hip joints, where viscous coefficient depends on the type of fin; (2) accordingly, for a given fin, movement at any amplitude and frequency is invariant when motion is normalized by amplitude; velocity and torque by the product of amplitude and frequency; and power and thrust by the square of the product of amplitude and frequency; (3) the power-specific thrust is invariant, regardless of fin type, amplitude of motion, and frequency of motion; and 4) the phasing between right and left legs does not have a significant effect on thrust generation (i.e., kicking in-phase and kicking in opposition behave similarly). The authors hope this data will be useful to other researchers interested in developing lower limb exoskeletons to augment underwater human finned swimming.
This article analyses the scholarly results concerning the social phenomenon of intermarriage. It specifically focuses on the similarities and differences in the latter in Europe, between migrants and host society members, and between national minorities and majorities. The study shows that while intermarriage between migrants and host society members is often seen as a vehicle for bridging social gaps and promoting social cohesion, intermarriages between national minorities and majorities is more likely to lead to erosion of minority identities and cultural traits. Common challenges faced by intermarried couples include resistance from family members and bureaucratic obstacles, with gender dynamics playing a crucial role, particularly in traditional societies where women often bear the brunt of cultural assimilation. Intermarriage also promotes the perspective of the integrative nature of nation-states without requiring intervention by the states themselves. The article underscores the importance of deepening the discourse on intermarriage and focusing on the impact of the latter on both migrant and national minority communities through both quantitative analyses and qualitative approaches. This may improve the understanding of the transformative potential and challenges of these unions.
This article advocates for a ‘sociolinguistics of deglobalization’ that focuses on the sociolinguistic impacts of major shifts in the world system that have taken place since 2008 and have become particularly salient amidst the covid pandemic. Drawing on case studies of China, Indonesia, Ethiopia, and Nigeria, we describe the period after 2008 as an emerging post-neoliberal epoch characterized by the intensifying of state power, constrained resistance, differential inclusion, and organized abandonment. Our article explores the theoretical, methodological, and ethical challenges of researching the sociolinguistic impacts of these developments. We also argue that our discipline's dominant approach to global-scale analysis—the sociolinguistics of globalization—has impeded our ability to perceive the emerging dynamics of deglobalization. Our call for a sociolinguistics of deglobalization is offered as both a provocation and invitation to our discipline to engage with the rapidly changing nature of world politics.

Early maladaptive schemas (EMS), dysfunctional patterns of thought and emotions originated during childhood, latent in most mental disorders, might play a role in the onset of alcohol use disorder (AUD), although their impact on prognosis remains unknown. Our aim is to determine the presence of EMS in patients with AUD and their role in the psychopathology and course of addiction (relapse and withdrawal time). The sample included 104 patients and 100 controls. The diagnosis of AUD was made according to the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) criteria, EMS were determined with the Young Schema Questionnaire in its Spanish version (YSQ–S3) and psychopathology with Symptom Checklist–27 (SCL–27). AUD group showed significantly higher scores in emotional deprivation, confused attachment, emotional inhibition and failure schemas. In addition, vulnerability schema correlated (> 0.500) with all subscales of SCL–27. Whereas social isolation, insufficient self-control and grandiosity schemas correlated with a higher number of relapses. But it was the grandiosity and punishment schemas that correlated with shorter abstinence time. These findings suggest that EMS are overrepresented in the AUD population and some correlate with psychopathology and worse AUD outcomes.
In dimension n = 1, we obtain $L^{p_1}(\mathbb R) \times\dots\times L^{p_m}(\mathbb R)$ to $L^p(\mathbb R)$ boundedness for the multilinear spherical maximal function in the largest possible open set of indices and we provide counterexamples that indicate the optimality of our results.

The present experimental study shows that a nozzle with optimal flexibility can enhance the impulse and entrainment of a pulsed jet. Near the nozzle exit, vortex rings emanating from the flexible nozzle move faster because of the timely release of the elastic energy (stored during the expansion) to the jet, which is maximized at the structural stiffness that needs to be optimally tuned to the jet acceleration. The total circulation, hydrodynamic impulse and entrained fluid volume are enhanced substantially. Interestingly, we find that the same condition for optimal flexibility to maximize the hydrodynamic impulse and circulation of the primary vortex ring of the continuous jet (Choi & Park, J. Fluid Mech., vol. 949, 2022, A39) holds universally for the pulsed jet, indicating that abrupt jet termination is irrelevant to the impulse augmentation mechanism. Compared to the rigid counterpart, increments of the impulse (${\sim }400\,\%$) and entrainment (${\sim }220\,\%$) of a pulsed jet in the present study are considerably larger than those ($200\,\%$ and $50\,\%$, respectively) in a continuous jet from previous studies, which is attributed to the significant suppression of negative pressure at the nozzle exit by the collapsing motion of the flexible nozzle in the phase with the jet-driven upstream propagation of the surface wave on the nozzle. This universal mechanism provides a guideline for a novel jet propulsor using a flexible nozzle, for example, for small-scale underwater robots.
Carbon stocks in root biomass and soil organic carbon (SOC) were analysed in tropical mountain cloud forest (TMCF) of Mexico. Additionally, the hypothesis that the concentration of roots in the forest is not homogeneous but that they are concentrated near the trunks of the trees was evaluated. Root biomass was 707.68 ± 150.41 g·m−2, which stores ∼353.85 ± 75.21 g·C·m−2. Coarse roots contributed 36.8%, fine roots 35.5%, and very fine roots 27.7% of the total biomass. The results did not support the hypothesis that fine roots are concentrated near the trunks of the trees. On average, SOC was 108.23 ± 33.21 Mg·C·ha−1. Mean C stored in the soil (C in roots + SOC) was 111.77 ± 32.97 Mg·C·ha−1. The TMCF is an ecosystem with a high potential for soil carbon storage, with similar C values reported to those in other tropical forests.
Metabolite supplementation during in vitro embryo development improves blastocyst quality, however, our understanding of the incorporation of metabolites during in vitro maturation (IVM) is limited. Two important metabolites, follistatin and choline, have beneficial impacts during in vitro culture; however, effects of supplementation during IVM are unknown. The objective of this study was to investigate combining choline and follistatin during IVM on bovine oocytes and subsequent early embryonic development. We hypothesized that supplementation of choline with follistatin would synergistically improve oocyte quality and subsequent early embryonic development. Small follicles were aspirated from slaughterhouse ovaries to obtain cumulus oocyte complexes for IVM with choline (0, 1.3 or 1.8 mM) and follistatin (0 or 10 ng/mL) supplementation in a 3 × 2 design. A subset of oocytes underwent transcriptomic analysis, the remaining oocytes were used for IVF and in vitro culture (IVC). Transcript abundance of CEPT1 tended to be reduced in oocytes supplemented with 1.8 mM choline and follistatin compared to control oocytes (P = 0.07). Combination of follistatin with 1.8 mM choline supplementation during maturation, tended (P = 0.08) to reduce CPEB4 in oocytes. In the blastocysts, HDCA8, NANOG, SAV1 and SOX2 were increased with choline 1.8 mM supplementation without follistatin (P < 0.05), while HDCA8 and SOX2 were increased when follistatin was incorporated (P < 0.05). The combination of choline and follistatin during oocyte maturation may provide a beneficial impact on early embryonic development. Further research is warranted to investigate the interaction between these two metabolites during early embryonic development and long-term influence on fetal development.
In the past decade, the Vietnamese lesbian, gay, bisexual, transgender, and other sexual orientations and gender identities (LGBT+) movement has succeeded in repositioning this population from the stigmatising label of “social evils” to a more positive social representation. Despite the limited space for civil society in this authoritarian environment, Vietnamese activists and non-governmental organisations (NGOs) have effectively changed public attitudes, improved visibility, and gained legal recognition for this marginalised community. This study uses qualitative data from interviews with twelve activists and fieldwork observations to explain how activist strategies in this setting align with the “service delivery” function of civil society. By examining how activists have addressed healthcare and education deficits, I demonstrate that activism in authoritarian regimes can be effective when it assists instead of challenges the government. The findings contribute to scholarship on global queer activism by demonstrating how a service delivery approach can achieve social change, highlighting the role of NGOs and international development in this process. Additionally, the findings expose existing challenges that hinder these activists’ efforts, showing how funding dependency and inadequate legal recognition can significantly limit the creativity and autonomy of grassroots activist groups.
Dispersal of gram-negative bacilli from sink drains has been implicated as a source of transmission in multiple outbreaks.
Methods:
In an acute care hospital, we assessed how often patient care supplies and other frequently touched items were within 1 meter of sink drains. We tested the efficacy of a ceiling-mounted far ultraviolet-C (UV-C) light technology for decontamination of sink bowls and surfaces near sinks with and without a wall-mounted film that reflects far UV-C light.
Results:
Of 190 sinks assessed, 55 (29%) had patient care supplies or other frequently touched items within 1 meter of the drain. The far UV-C technology reduced Pseudomonas aeruginosa, Enterobacter cloacae and Candida auris on steel disk carriers by ≥1.5 log10 colony-forming units (CFU) in 45 minutes. On inoculated real-world items, ≥1.9 log10 CFU reductions in P. aeruginosa were achieved on sites in line with the light source versus 0.4–1.8 log10 CFU reductions on shaded surfaces. The addition of the reflective surface significantly enhanced efficacy in shaded sites (P < 0.01).
Conclusions:
In a hospital setting, patient care supplies and other frequently touched items were often in proximity to sinks. The far UV-C light technology could potentially be useful for sink decontamination in high-risk areas.
After its initial founding by the Council on Religion and Law at Harvard, the Journal of Law and Religion had its first life at Hamline University School of Law beginning in 1983. This essay is a history of its second life—from 1987/1988 to 2013—describing the vision and the people who pursued that vision through the journal in those years and some of the roundtables and symposia it published.
