The influence mechanism of relational capital on adaptive behaviors of Chinese expatriates in Latin America
Authors: Nie Ting , Xie Lida , Gong Caijun , Huang Yiying , Yan Qiao 
Published: November 2024

Purpose
In line with the theory of planned behavior, this study aims to examine the mediating effect of cultural identity and role identity between relational capital and adaptive behavior, and the moderating effect of willingness to learn.

Design/methodology/approach
Data were collected from 241 Chinese expatriates in Latin America through a two-wave survey.

Findings
The findings indicate that expatriates’ perceived relational capital can promote adaptive behaviors by enhancing their cultural identity and role identity. Willingness to learn positively moderates the indirect effects of relational capital on adaptive behaviors through cultural identity and role identity. For expatriates with a high willingness to learn, the impact of relational capital on their adaptive behaviors through cultural identity and role identity is stronger.

Originality/value
This study extends empirical research on expatriate adaptation. Organizations should promote the accumulation of expatriates’ relational capital while they are working abroad. Meanwhile, willingness to learn should be considered as a criterion when selecting expatriates.

Linear and energy stability analyses of onset of Darcy-Bénard convection due to combustion
Authors: Siddheshwar P.G. , Nandal Reena 
Published: November 2024

Purpose
This paper aims to perform a linear and nonlinear analysis of the stability of a chemically reacting Newtonian fluid in a Darcy porous medium. The purpose of selecting both analyses is to investigate the probability of subcritical instability resulting from combustion.

Design/methodology/approach
The chemical reaction problem in a Darcy porous medium with Arrhenius kinetics is considered. The effect of the Frank-Kamenetskii number on the linear and nonlinear stability is analysed. The critical eigenvalue is obtained numerically by the Chebyshev pseudospectral method for both analyses.

Findings
The inference from the two analyses is that in the presence of combustion, the situation in the Darcy−Bénard convection problem can lead to subcritical instability. It is found that the value of the critical Frank-Kamenetskii number keeps on changing as the lower boundary temperature changes, beyond the critical value of the Frank-Kamenetskii number where the system splits, going from a steady condition to an explosive state.

Originality/value
The Chebyshev pseudospectral approach has been applied to address the combustion problem in this research. The normal mode methodology and energy method are used for linear and nonlinear analyses, and the effects of nonlinear factors are examined by comparing the outcomes.

Authors: Rosali Leann Jester Daus , Dicto Princess Joy , Erojo Kreen 
Published: November 2024

Purpose
This study aims to explore the various ways Filipino adolescents understand their experiences of isolation due to the COVID-19 pandemic, focusing on their perceptions of gains and losses during prolonged quarantine.

Design/methodology/approach
A phenomenographic approach was used, involving semi-structured interviews with 17 adolescents aged 16–19 years from a private senior high school in the Philippines. Data were collected through online surveys and virtual interviews, analyzed to identify categories of understanding and construct an outcome space.

Findings
Adolescents perceive isolation in three primary ways: as a constraint, a necessity and an opportunity. These perceptions reveal a hierarchy of expanding awareness impacting their physical, emotional and social well-being. Isolation as a constraint highlighted limitations and losses, as a necessity emphasized safety and rational acceptance and as an opportunity focused on personal growth and strengthened relationships.

Research limitations/implications
The qualitative nature and specific demographic focus limit generalizability. The findings provide valuable insights for understanding adolescent experiences and can inform targeted interventions to support their emotional well-being during and post-isolation.

Practical implications
Programs and interventions designed based on these findings can help adolescents cope with negative emotions associated with isolation, promote their well-being and facilitate smoother transitions back to normalcy post-quarantine.

Social implications
Understanding adolescents’ perspectives on isolation can guide the development of supportive policies and community programs that address their mental health needs and foster resilience in similar future scenarios.

Originality/value
This study fills a gap in research by providing a detailed phenomenographic analysis of how Filipino adolescents perceive isolation during the COVID-19 pandemic, offering a nuanced understanding of their experiences that can inform both local and broader contexts.

Published: November 2024

PurposeThe article aims to explore how the military police in Brazil’s Northern Region incorporate “difference” and “diversity” into leadership, focusing on women in leadership roles. It examines institutional changes in leadership styles and the development of inclusive practices. The goal is to understand the competencies women bring to police leadership and how these can transform organizational culture.Design/methodology/approachThe study employed in-depth interviews with 20 women’s police leaders in Pará, using MAXQDA for data analysis and criteria sampling for participant selection to achieve data saturation.FindingsThe study results indicate that women’s leadership in the Military Police of Pará fosters a new organizational culture, emphasizing shared and transformational leadership. Women’s leaders are seen as adaptable and resilient, capable of balancing professional performance with emotional management. Traits such as empathy and sensitivity are prominent, creating a more humanized work environment. Additionally, the creativity and charisma of women’s leaders facilitate the development of innovative solutions to complex problems, demonstrating the transformative impact of women’s leadership within the police.Research limitations/implicationsThe study’s limitations include its focus on a specific region with a small sample size, reliance on self-reported data, which may introduce bias, and findings deeply embedded in the local cultural contexto in the police.Practical implicationsThe practical implications of this study include encouraging the development of formal networks and mentorship opportunities, particularly those led by women. These initiatives aim to promote gender equity within the police force by preventing women from being disadvantaged in competitive processes such as exams and performance evaluations, thereby eliminating implicit biases. Implementing mentorship programs that connect experienced women officers with aspiring officers can facilitate the exchange of practical knowledge and experience while developing essential skills like empathy, compassion and emotional balance.Originality/valueThe originality and value of this study lie in its focus on the unique competencies and leadership styles of female leaders in the Military Police of Northern Brazil. It highlights how these leaders introduce empathy, creativity and resilience into the traditionally male-dominated police culture, fostering a more inclusive and effective organizational environment. This research fills a gap by providing insights into how female leadership can transform police practices, emphasizing the importance of diversity and gender-sensitive approaches in law enforcement.
The Modern Epidemic of Autoimmunity
Authors: Zheng Jie‐Fu , Lee Yung‐Heng , Leong Pui‐Ying 
Published: November 2024

ABSTRACTAutoimmunity occurs when the immune system mistakenly attacks the body, but the presence of autoantibodies, such as antinuclear antibodies (ANAs), does not always lead to autoimmune diseases. Globally, autoimmunity is on the rise, influenced by socioeconomic factors, environmental exposure, diet, and stress. Climate change and pollution further exacerbate risks. The COVID‐19 pandemic has worsened the issue, with unvaccinated individuals showing higher rates of autoimmune conditions postinfection. Preventive strategies, including healthy diets, stress management, and vaccination, are crucial in combating this growing epidemic. Collaboration between individuals, healthcare providers, and policymakers is critical to mitigate the rise in autoimmune disorders and enhance public health.
swaRmverse: An R package for the comparative analysis of collective motion
Authors: Papadopoulou Marina , Garnier Simon , King Andrew J. 
Published: November 2024

Abstract

Collective motion, that is the coordinated spatial and temporal organisation of individuals, is a core element in the study of collective animal behaviour. The self‐organised properties of how a group moves influence its various behavioural and ecological processes, such as predator–prey dynamics, social foraging and migration. However, little is known about the inter‐ and intra‐specific variation in collective motion. Despite the significant advancement in high‐resolution tracking of multiple individuals within groups, providing collective motion data for animals in the laboratory and the field, a framework to perform quantitative comparisons across species and contexts is lacking.

Here, we present the swaRmverse package. Building on two existing R packages, trackdf and swaRm, swaRmverse enables the identification and analysis of collective motion ‘events’, as presented in Papadopoulou et al. (2023), creating a unit of comparison across datasets. We describe the package's structure and showcase its functionality using existing datasets from several species and simulated trajectories from an agent‐based model.

From positional time‐series data for multiple individuals (x‐y‐t‐id), swaRmverse identifies events of collective motion based on the distribution of polarisation and group speed. For each event, a suite of validated biologically meaningful metrics are calculated, and events are placed into a ‘swarm space’ through dimensional reduction techniques.

Our package provides the first automated pipeline enabling the analysis of data on collective behaviour. The package allows the calculation and use of complex metrics for users without a strong quantitative background and will promote communication and data‐sharing across disciplines, standardising the quantification of collective motion across species and promoting comparative investigations.

Published: November 2024

AbstractBackgroundProblematic alcohol use (PAU) is highly prevalent in the United States. Although bereavement, a highly stressful and ubiquitous experience across the lifespan, is believed to increase the risk for PAU based on a small number of studies, research using large diverse samples of bereaved adults has yet to be conducted. Therefore, relations between PAU and bereavement remain poorly understood, hampering the reach and effectiveness of alcohol interventions. The current study addresses this limitation by investigating rates and correlates of PAU and service utilization among a large national sample of bereaved adults.MethodsParticipants were adults who reported the death of a significant other in their lifetime (N = 1529). Most participants identified as female (69.1%) and White (68.2%), with an average age of 44.7 (SD = 16.29). Online self‐report surveys assessed the prevalence of PAU using the AUDIT‐C, mental health service utilization, and associated characteristics.ResultsNearly one‐third (n = 463; 30.3%) screened positive for PAU, which surpasses rates found in the general US population. After accounting for other characteristics, time since the death (OR, 3.63; 95% CI, 2.59–5.08) and meeting presumptive criteria for depression (OR, 2.28; 95% CI, 1.64–3.18) and prolonged grief disorder (PGD; OR, 1.66; 95% CI, 1.13–2.25) significantly increased risk for PAU among the bereaved. Approximately half (n = 244; 52.7%) of bereaved adults with PAU received any mental health service since the death. Time since the death (OR, 4.19; 95% CI, 2.38–7.48) and presumptive depression (OR, 2.16; 95% CI, 1.25–3.74) were associated with service utilization after accounting for other characteristics.ConclusionsThe high prevalence of PAU among bereaved adults, particularly among those with a diagnosis of PGD, and limited use of support services underscore the need for greater empirical attention and integrated substance use care for bereaved adults.

Published: November 2024

SummaryResazurin, a phenoxazine used in cell viability assays, acts in vitro as an anti‐leukaemic compound through the production of cellular reactive oxygen species (ROS) resulting in mitochondrial dysfunction and cell death. However, the in vivo tolerance and efficacy of resazurin in cancer are unknown. In this study, we investigated the in vitro and in vivo effects of resazurin in acute myeloid leukaemia (AML). Resazurininduced cell death in a dose‐dependent manner in AML cell lines and reduced proliferation and colony formation in ex vivo treated patient‐derived AML cells. Cells treated with a reduced dose of resazurin for 72 h acquired a more mature immunophenotype suggesting cell differentiation as a mechanism contributing to the anti‐leukaemic effect. In vivo optical imaging in healthy mice demonstrated a reduction of resazurin to resorufin within 30 min and non‐detectable after 2 h, supporting dosing twice daily as optimal. In subcutaneous and orthotopic models of MV4‐11 AML in NOD/SCID IL2rγnull mice, anti‐tumour effects and an increased survival were found at a dose level of 75 mg/kg twice daily without observed toxicity. Our results suggest that resazurin represents a novel experimental therapeutic for the treatment of AML.

Published: November 2024

ABSTRACTBackgroundFocal to bilateral tonic–clonic seizures (FBTCS) represent the most severe seizure type in temporal lobe epilepsy (TLE), associated with extensive network abnormalities. Nevertheless, the genetic and cellular factors predispose specific TLE patients to FBTCS remain poorly understood. This study aimed to elucidate the relationship between brain morphometric alterations and transcriptional profiles in TLE patients with FBTCS (FBTCS+) compared to those without FBTCS (FBTCS−).MethodsWe enrolled 126 unilateral TLE patients (89 FBTCS+ and 37 FBTCS−) along with 60 age‐ and gender‐matched healthy controls (HC). We assessed gray matter volume to identify morphometric differences between patients and HC. Partial least squares regression was employed to investigate the association between the morphometric disparities and human brain transcriptomic data obtained from the Allen Human Brain Atlas.ResultsCompared with HC, FBTCS+ patients exhibited morphometric alterations in bilateral cortical and subcortical regions. Conversely, FBTCS− patients exhibited more localized alterations. Imaging transcriptomic analysis revealed both FBTCS− and FBTCS+ groups harbored genes that spatially correlated with morphometric alterations. Additionally, pathway enrichment analysis identified common pathways involved in neural development and synaptic function in both groups. The FBTCS− group displayed unique pathway enrichment in catabolic processes. Furthermore, mapping these genes to specific cell types indicated enrichment in excitatory and inhibitory neurons in the FBTCS− group, while FBTCS+ group only enriched in excitatory neurons. The distinct cellular expression differences between FBTCS− and FBTCS+ groups are consistent with the distribution patterns of GABAergic expression.ConclusionWe applied imaging transcriptomic analysis linking the morphometric changes and neurobiology in TLE patients with and without FBTCS, including gene expression, biological pathways, cell types, and neurotransmitter receptors. Our findings revealed abnormalities in inhibitory neurons and altered distribution patterns of GABAergic receptors in FBTCS+, suggesting that an excitatory/inhibitory imbalance may contribute to the increased susceptibility of certain individuals to FBTCS.

Authors: Deniz Umay Hazar , Cevher Kalburan Nilgün 
Published: November 2024

ABSTRACTThis cross‐cultural multiple case study investigates the approaches of educators in nature‐based preschools in Turkey and Germany towards risky play, exploring factors influencing play behaviours and educator roles. Four educators from Turkey and three educators from Germany participated in the study. Through qualitative analysis of interviews and observations, three themes emerged: factors affecting play (including age, gender, environment, and cultural norms), educator roles (pre‐play, during play, post‐play), and risky play requirements (rules, risk management). Findings reveal cultural differences in attitudes towards risk, the impact of policy frameworks on practice, and the importance of professional development for educators. Policy implications include the need for supportive regulations promoting outdoor play, while future research should focus on longitudinal studies to assess long‐term outcomes of risky play and explore innovative approaches to risk management. This study underscores the importance of creating environments that empower children to engage in enriching, developmentally appropriate play experiences while ensuring their safety and well‐being.
Modeling of Stress–Strain Fields Below U‐Notch Root Using Plasticity Approximation Rules Under Variable‐Amplitude Loading
Authors: Asplund Anton , Remes Heikki , Ono Yuki 
Published: November 2024

ABSTRACTThis paper evaluates the applicability of Neuber's and equivalent strain energy density (ESED) rules to predict the material response below the root of a sharp U‐notch under variable‐amplitude (VA) loading for crack propagation simulations. The Voce–Chaboche (V‐C) combined hardening constitutive model, coupled with the above‐mentioned approximation rules, is used to resolve the elasto‐plastic response over a range of depths below the notch root. The response at each load reversal is extracted, and the maximum and minimum stress and strain quantities are used to evaluate fatigue damage using the Smith–Watson–Topper parameter. Results from approximation rules are compared to finite element method (FEM) at and below the notch root. Prediction accuracy varied at different points below the root depending on the size of the plastic zone, with predictions made using the original Neuber's and ESED rules being less accurate below the root. Applying stress redistribution correction to the stress field improves its accuracy below the root; however, strain values are significantly amplified as a result. A modified Neuber's rule with stress redistribution and constraint corrections predicts the distribution of the material response and fatigue damage with consistent accuracy.

Published: November 2024

ABSTRACTThe diversity of biotic and abiotic sounds that fill underwater ecosystems has become polluted by anthropogenic noise in recent decades. Yet, there is still great uncertainty surrounding how different acoustic stimuli influence marine and freshwater (i.e., aquatic) communities. Despite capabilities to detect and produce sounds, aquatic invertebrates are among the most understudied taxa within the field of soundscape ecology. We conducted a meta‐analysis to understand how sounds from various sources influence the behavior and physiology of aquatic invertebrates. We extracted 835 data points from 46 studies conducted in 15 countries. The resulting data included 50 species, a range of experimental conditions, and four sound categories: anthropogenic, environmental, synthetic, and music. We used meta‐analytic multivariate mixed‐effect models to determine how each sound category influenced aquatic invertebrates and if responses were homogeneous across taxa. Our analyses illustrate that anthropogenic noise and synthetic sounds have detrimental impacts on aquatic invertebrate behavior and physiology, and that environmental sounds have slightly beneficial effects on their behavior. Defence responses were the most impacted behaviors, while the most prominent physiological responses were related to biochemistry, genetics, and morphology. Additionally, arthropods and molluscs exhibited the most pronounced physiological responses to anthropogenic and synthetic noise. These findings support the conclusion that many invertebrate species are sensitive to changes in aquatic soundscapes, which can cause adverse or favorable consequences to individuals and populations, dependent on the sound source. This quantitative synthesis highlights the necessity of including marine and freshwater invertebrates in acoustic exposure studies, aquatic ecosystem assessments, and emerging noise pollution policies.
