Predictive modeling of fatigue and rutting parameters for asphalt cement modified with pretreated oil palm clinker using artificial neural network algorithms to enhance pavement performance

Currently, the viscoelastic properties of standard asphalt cement cannot sustain the increasing demands resulting from heavier traffic loads, greater stress levels, and changing environmental conditions. Thus, the usage of modifiers is encouraged. Also, the Sustainable Development Goal (SDG) encourages the use of waste resources and emerging technologies in asphalt pavement technology. This study intends to harness this gap by examining the use of oil palm clinker (OPC) as an asphalt-cement modification to improve its viscoelastic properties using an innovative prediction approach. The modified asphalt-cement was produced by varying the acid-treated OPC powder (OPCP) content at 2%, 4%, 6%, and 8% and the rutting and fatigue performance was evaluated. This paper also presents an optimization approach and prediction comparison based on statistical modeling and artificial intelligence (AI) algorithms for the fatigue and rutting parameters of the modified asphalt cement. Model variables for the predictive models include OPCP content and test temperatures. The AI algorithms use 70% of the data for training, 15% for testing, and 15% for validation. The results showed that the incorporation of OPCP improves the properties of pure asphalt-cement by increasing stiffness and temperature susceptibility and that the crystalline phase of Si–O formed a novel structural group Si–OH. The RSM R2 for rutting for unaged and RTFO aged responses was (99.743 and 99.893), the RMSE was (436.210 and 954.945), and the MRE was 3.269 and 2.315) for the model statistical performance index, respectively. The ANN R2 for rutting for unaged and RTFO aged responses were (99.903 and 99.970) the RMSE (106.283 and 528.500) and MRE (1.759 and 1.039). PAV fatigue RSM R2 values were (99.984), RMSE (77979.750), and MRE (12.089), while ANN R2 values were (99.997), RMSE (53933.500), and MRE (5.262). The findings demonstrated that the generated model and algorithm could predict the fatigue and rutting performance of the OPCP-modified asphalt cement accurately with the AI algorithms model outperforming the statistical model. Also, the study aligns with SDG 9 by developing advanced modeling techniques and enhancing infrastructure durability through innovative use of modified materials as well as SDG 12 by incorporating recycled materials into sustainable production practices.

Association of Limited Health Literacy With Clinical and Patient-Reported Outcomes in Individuals With Systemic Lupus Erythematosus.

Health literacy is an important social determinant of health, with limited health literacy associated with worse health outcomes. This study examined the associations between limited health literacy with patient-reported outcomes and disease activity/damage among 267 Black women with active systemic lupus erythematosus (SLE) enrolled in the Peer Approaches to Lupus Self-Management (PALS) program. The three-item Chew Health Literacy Screening was used to dichotomize those reporting in the "limited" range on any item with outcomes compared via generalized linear models. Baseline surveys and assessments obtained at study entry as part of the PALS study were used. Primary outcomes included disease activity and lupus damage; other secondary outcomes included patient activation, self-efficacy, physician/patient communication, and quality of life. The study included 267 Black women with SLE. In covariate-adjusted analyses, participants with limited health literacy (88 [33%]) were more likely to have lower patient activation (Patient Activation Measure P < 0.0001), lower self-efficacy (Lupus Self-Efficacy P < 0.0001), higher lupus damage (self-administered Brief Index of Lupus Damage P=.016), higher disease activity (Systemic Lupus Activity Questionnaire symptom severity P=0.006), and worse physician/patient communication (patient-centered care P < 0.0001) compared to those with adequate health literacy. Those with limited health literacy also reported worse lupus quality of life (P=0.0004) and greater levels of stress (Perceived Stress Scale-4 P < 0.0001) and were 2.4 times more likely to have probable major depression (Patient Health Questionnaire Depression Scale-8 of ≥10 P=0.004) and probable anxiety disorder (General Anxiety Disorder-7 of ≥10 P=0.007) compared to those with adequate health literacy. Black women with SLE and limited health literacy have worse clinical outcomes and represent a particularly vulnerable population with significantly disparate health outcomes. These findings suggest health literacy and complexities of managing SLE may impair clinical care in multiple domains, ultimately contributing to higher disease activity and death/damage, and are important to address in clinical care and future interventions in patients with SLE.

IntroductionBlack emerging adults (18–28 years) have the highest risk of short sleep duration and obesity. This increased risk may be partly explained by greater stress levels, which may result from...

The Effects of COVID-19 on the Mental Health of Children and Adolescents: A Review.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has profoundly affected global health and well-being. As part of the Coronaviridae family, SARS-CoV-2 joins a diverse group of viruses found in both humans and various animal species, including bats, camels, and cats. The pandemic has led to widespread social isolation, reduced physical activity, and significant lifestyle changes, posing potential risks to individuals' mental and emotional health. This review aims to explore the implications of COVID-19 on the mental health of children and adolescents, given the limited attention this population has received in the medical literature. Multiple research studies in several countries have found that the COVID-19 pandemic is associated with greater stress levels, depression, anxiety, insomnia, drug misuse, and other mental health challenges among young individuals. Understanding the long-term effects of the pandemic on mental health is crucial for developing effective interventions and support systems to promote resilience and well-being in children and adolescents. Even after the pandemic ends,it is crucial to prioritize understanding the long-term impacts of the pandemic on mental health, integrating findings into public health strategies, addressing mental healthcare disparities, and fostering resilience in children and adolescents. Achieving these objectives requires collaborative efforts across various sectors to ensure equitable access to mental health resources and the implementation of sustainable solutions for the well-being of young people in the aftermath of the pandemic.

Stress factors and food purchase prioritization during the pandemic of coronavirus disease 2019

BackgroundThe pandemic of coronavirus disease 2019 (COVID-19) pandemic confinement has an impact on stress levels, which causes changes in food purchase and consumption behaviors. The objective of this study is to associate food purchase prioritization with stress level during the COVID-19 pandemic confinement. MethodsMulticenter, observational and cross-sectional study, an online questionnaire that included data on sociodemographic variables, stress factors and food purchase prioritization was disseminated through digital platforms and social networks. ResultsA number of 6,357 participants were included, of whom 83.6% were female, 56.3% were from the middle socioeconomic level, 71.2% had completed higher education and 78.3% had a job. At greater stress levels it was observed a higher prioritization of canned foods (Odds ratio (OR): 1.91, 95% CI: 1.56; 2.34), sweets (OR: 1.58, 95% CI: 1.06; 2.34) and flours (OR: 1.45, 95% CI: 1.25; 1.68). While lower stress levels are associated with nuts (OR: 0.75, 95% CI: 0.66; 0.85), vegetables (OR: 0.82, 95% CI: 0.72; 0.94), and fruits (OR: 0.90, 95% CI: 0.80; 1.01), after adjusting for confounders. ConclusionsThere is an association between food purchase prioritization and stress level during the COVID-19 confinement. At greater stress levels, individuals purchase more food, both healthy and unhealthy. The later may have a negative impact on people's health, leading to or further aggravating malnutrition by excess and nutrition-related noncommunicable diseases.

Leisure time and parenting in Europe: a more difficult equation for mothers?

AbstractObjectiveThis paper analyzes gender inequalities in leisure time within coresident opposite‐sex couples with and without children at home in five European countries to evaluate the gendered parental impact in leisure time.BackgroundIn European societies, women continue to bear much of the physical and mental burden involved in running a household and managing family life resulting in greater levels of stress and time deprivation. Time spent in leisure has been associated with better physical and psychological wellness. Understanding how gender influences the distribution of leisure time among couples living with and without children at home, and how these effects differ across European countries, is important to understand individual and couples' well‐being.MethodDrawing on information from the Multinational Time Use Study for 15,024 matched couples residing in Spain, Italy, France, Finland, and the United Kingdom, we conduct a series of ordinary‐least‐squares regression analyses with country fixed effects.ResultsThe general trends reveal that women in Europe allocate less time to leisure and that mothers experience lower leisure of high quality compared to their partners when their children are below the age of 5. However, Finnish and British couples exhibit a more egalitarian distribution of leisure time regardless of their parental status, particularly when compared to Italian and Spanish ones.ConclusionThis study unveils a gendered use of leisure time, as well as a gendered parental impact when children are young. However, the impact of women's second shift in leisure time varies across countries, suggesting a cultural and institutional effect.ImplicationsThese findings have implications for researchers, health professionals, and policymakers concerned with understanding and alleviating situations of overstress, time poverty, and depression among women, but especially among mothers of young children.

Factors that influence stress in caregivers of 5-year-old children with hearing loss wearing hearing aids or cochlear implants

ObjectiveStress levels among caregivers of children with hearing loss could influence caregiver-child interactions and ultimately, children's developmental outcomes. Given the limited understanding of stress levels among caregivers of Australian children with hearing loss, the present study aimed to examine stress in caregivers of 5-year-old children with hearing loss wearing hearing aids or cochlear implants and to identify factors associated with greater stress levels. MethodsA total of 99 caregivers of 70 hearing aid users and 29 cochlear implant users participated in the study. Caregivers' stress was measured using the 68-item Pediatric Hearing Impairment Caregiver Experience (PHICE) questionnaire that examines caregivers’ context-specific stress levels in relation to caring for a child with hearing loss. Factors contributing to stress were identified in relation to eight domains including communication, education, emotional well-being, equipment, financial, healthcare, social, and support. ResultsAcross domains, the three most common predictors of increased stress were the use of cochlear implants over hearing aids, use of sign and oral language (mixed) over oral language as the communication mode at home, and increased behavioural difficulties of the child. ConclusionOverall, reported stress levels among Australian caregivers were low. Identified factors influencing stress levels can inform service provision improvement.

Coping and mood in carers of people with Parkinson’s disease – an anonymized online survey

AbstractBackgroundFamily and informal carers play a substantial role in the care of patients with Parkinson’s disease (PD) especially those who develop neuropsychiatric symptoms and dementia. As PD progresses, carers are at increased risk for poor health outcomes and greater levels of stress. Furthermore, negative emotional states, such as depression and anxiety with stress, are major risk factors for the development and maintenance of poor adaptive coping strategies. However, the literature examining these in PD carers is sparse. We aimed to identify and examine relationships between mood symptomatology and coping strategies in carers of people with PD.MethodsAn anonymised self‐administered online survey was conducted for data collection within the UK (Ethics Approval Ref‐LRU‐21/22‐28386). The survey consisted of questions regarding demographics, coping strategies and mood symptoms. A snowballing sampling was used to recruit via advertising in various Parkinson’s support groups within UK. Participants who were unpaid carers (family, partner or friend) of people with PD above the age of 18 years, fluent in English and had a device to do the online survey were eligible.Results105 carers for people with PD participated online between 23rd May 2022 to 15th July 2022. 96.2% of the carers were women and most in the age range of 45‐64 years (57.1%). 93.3% of the carers were spouse or partners, lived (89.5%) and taken care of the person with PD for over 5 years (54.3%), providing care ‘most of the time’ (59%). 61.9% PD persons had dementia and 29.5% had psychosis symptoms. We found that PD carers used more of non‐adaptive than adaptive coping strategies. 91.4% of carers had anxiety and 92.4% had depressive symptoms in varying frequency. Non adaptive coping strategies were associated with increased mood symptoms.ConclusionsCarers with adaptive coping strategies had lower frequency of mood symptoms. Further research in larger samples is needed not only to understand the relationships of coping strategies and mood symptoms in carers of people with PD but also important to devise interventions to support these carers to improve their well‐being.

The Women Farmer Stress Inventory: Examining women farmer stress in the United States Corn Belt.

While women identifying as primary farmers have increased in the United States, there has not been research focused on the antecedents of stress and quality of life among women farmers in particular. This study set out to construct a Women Farmer Stress Inventory (WFSI), test its dimensionality, and assess its criterion-related validity by looking at its relationship with subjective wellbeing as measured by the Satisfaction with Life Scale (SWLS). We then examined sociodemographic and farm-level correlates to assess their relationship with stress. We utilized responses from a random sample of 592 Iowan women farmers who responded to a mailout survey that included the WFSI. We conducted exploratory factor analysis to identify the factorial structure of the WFSI, and used linear regression to evaluate how sociodemographic and farm-level characteristics were related to each factor. The analysis revealed 5 unique factors that reflected different aspects of women farmer stress: time pressures and workload, environmental concern, external stressors from governments and market, interpersonal relationships, and rural amenities. All factors except rural amenities had high levels of internal consistency (Cronbach's alpha >0.80) and were validated using the external criteria of SWLS measures. Young age, being married, and engagement in off-farm work, and smaller farm size were associated with greater levels of stress across most domains. The WFSI is a promising tool that shows high internal consistency and is validated with life satisfaction. Our study also finds certain sociodemographic and farm characteristics associated with different stress domains, which could inform both future research and community-based interventions.

Impacts of COVID-19 on Stress in Middle School Teachers and Staff in Minnesota: An Exploratory Study Using Random Forest Analysis.

While the COVID-19 pandemic has negatively impacted many occupations, teachers and school staff have faced unique challenges related to remote and hybrid teaching, less contact with students, and general uncertainty. This study aimed to measure the associations between specific impacts of the COVID-19 pandemic and stress levels in Minnesota educators. A total of 296 teachers and staff members from eight middle schools completed online surveys between May and July of 2020. The Epidemic Pandemic Impacts Inventory (EPII) measured the effects of the COVID-19 pandemic according to nine domains (i.e., Economic, Home Life). The Kessler-6 scale measured non-specific stress (range: 0-24), with higher scores indicating greater levels of stress. Random forest analysis determined which items of the EPII were predictive of stress. The average Kessler-6 score was 6.8, indicating moderate stress. Three EPII items explained the largest amount of variation in the Kessler-6 score: increase in mental health problems or symptoms, hard time making the transition to working from home, and increase in sleep problems or poor sleep quality. These findings indicate potential areas for intervention to reduce employee stress in the event of future disruptions to in-person teaching or other major transitions during dynamic times.

Hippocampal Subfields, Daily Stressors, and Resting Cortisol in Individuals at Clinical High-Risk for Psychosis

The hippocampus, comprised of functionally distinct subfields, both regulates stress and is affected by it during psychosis pathogenesis. Hippocampal abnormalities are evident across psychosis spectrum and are associated with aberrant cortisol levels and greater environmental stressors exposure. These associations, particularly at the subfield-level, are poorly understood in individuals at clinical high-risk (CHR) for psychosis- a population characterized by an interplay between environmental stressors and biological susceptibility. A total of 121 participants including 51 CHR (mean age=18.61) and 70 healthy controls (HC; mean age=18.3) were enrolled. Participants completed a structural scan, salivary cortisol assays, and a self-report measure assessing distress from daily stressors exposure (DSI). Hippocampal subfield segmentation was conducted using Freesurfer. Smaller hippocampal subfields were associated with greater stress levels. Greater DSI was associated with lower volumes in CA1 (r=-.38) and CA2/3 (r=-.29), but not in CA4/DG (r=-.28), presubiculum (r=-.09), or subiculum (r=-.17). Higher resting cortisol was associated with lower volumes in presubiculum (r=-.4) but not subiculum (r=-.22), CA1 (r=.08), CA2/3 (r=.1), or CA4/DG (r=-.005). Regressions indicated effects for CA1 and DSI (b=.57, p=.03) and presubiculum and cortisol (b=.61, p=.02) are specific to CHR participants relative to HCs. The findings provided insights into links between stress and brain vulnerability during psychosis-risk period. Regional differences highlighted potentially different mechanisms by which stress impacts specific subfields. Presubiculum may be more susceptible to the impact of early stress on HPA-axis and cornu amonis to acute stressors.

Stress Assessment Questionnaires

Stress risk assessment questionnaires are tools used to evaluate an individual’s risk of experiencing stress in a particular environment or situation. These questionnaires can be used in a variety of settings, such as the workplace, school or healthcare setting. They typically include a series of questions that assess an individual’s physical and psychological symptoms, as well as their coping strategies and support systems. The results of the questionnaire can be used to identify individuals who may be at risk for stress-related problems and to develop interventions to reduce their risk. Some examples of stress risk assessment questionnaires are the Perceived Stress Scale (PSS) and the Stress Symptoms Inventory (SSI). The best stress questionnaire to use in the workplace will depend on the specific goals and needs of the organization. However, there are some commonly used and validated questionnaires that have been specifically developed for use in the workplace. The Job Stress Survey (JSS) is a self-report questionnaire that assesses the level of stress experienced by an individual in their workplace. It was developed by Paul E. Spector in 1985. The JSS consists of 57 items that assess six factors related to job stress: role ambiguity, role conflict, lack of social support, lack of control, demand-control and overcommitment. The items are rated on a five-point Likert scale, with higher scores indicating a greater level of stress. The JSS has been found to be a reliable and valid measure of job stress and has been used in a wide range of populations, including employees in various industries and job types. The results of the JSS can be used to identify specific sources of stress within an organization and to develop interventions to reduce stress for employees. The JSS is considered a comprehensive tool; it covers different aspects of work stress and can be used in different settings and industries.

Psychological distress in Portuguese university students during COVID-19 pandemic: relationship with stress, sleeping and emotion regulation strategies

IntroductionDuring the COVID-19 pandemic outbreak, psychological distress, anxiety and depression reached new highs associated with a number of variables such as pandemic related-stress and sleep difficulties. These later two are known to be the precipitant and risk factors for psychological distress/mental disorders, respectively, and negative cognitive emotion regulation strategies can also have a key role on psychological/mental health problems generation and maintenance.ObjectivesTo study stress, sleep difficulties and the use of cognitive emotion regulation strategies by groups of students with different levels of psychological distress during the COVID-19 pandemic.Methods496 university students (mean age ± SD=20.99 years ± 2.27; 78.6% women) completed an online questionnaire between January and April, 2021, which included the Mental Health Inventory, the Perceived Stress Scale (PSS) and the Cognitive Emotion Regulation Questionnaire, as well as three questions from the Insomnia Scale to evaluate Difficulties in Initiating Sleep (DIS), Maintaining Sleep (DMS) and Early Morning Awakening (EMA). A Sleep Difficulties Index (SDI) was calculated by summing the scores of these three items.Results18.3% of the students showed high levels of psychological distress (group 1; scores 1 SD =/&lt; Mean), 62.7% average levels (group 2), and 19% low levels (group 3; Scores 1SD =/&gt;Mean). The group 1, compared with group 3, showed higher levels of sleeping difficulties (DIS, DMS, EMA and SDI), greater stress levels and an increased use of negative emotion regulation strategies, as well as a lesser use of positive emotion regulation strategies. Furthermore, the group 2, with average levels of psychological distress is significantly distinct from the group with better mental health when comparing these same variables.ConclusionsAlmost one fifth of the Portuguese university students report elevated levels of psychological distress during the COVID-19 pandemic. Clinical interventions to promote psychological/mental health in this population should focus on reducing stress, promoting adequate sleep habits, reducing the use of negative cognitive emotion regulation strategies and increasing the use of positive ones.Disclosure of InterestNone Declared

Advanced brain age correlates with greater rumination and less mindfulness in schizophrenia

BackgroundIndividual variation in brain aging trajectories is linked with several physical and mental health outcomes. Greater stress levels, worry, and rumination correspond with advanced brain age, while other individual characteristics, like mindfulness, may be protective of brain health. Multiple lines of evidence point to advanced brain aging in schizophrenia (i.e., neural age estimate > chronological age). Whether psychological dimensions such as mindfulness, rumination, and perceived stress contribute to brain aging in schizophrenia is unknown. MethodsWe estimated brain age from high-resolution anatomical scans in 54 healthy controls (HC) and 52 individuals with schizophrenia (SZ) and computed the brain predicted age difference (BrainAGE-diff), i.e., the delta between estimated brain age and chronological age. Emotional well-being summary scores were empirically derived to reflect individual differences in trait mindfulness, rumination, and perceived stress. Core analyses evaluated relationships between BrainAGE-diff and emotional well-being, testing for slopes differences across groups. ResultsHC showed higher emotional well-being (greater mindfulness and less rumination/stress), relative to SZ. We observed a significant group difference in the relationship between BrainAge-diff and emotional well-being, explained by BrainAGE-diff negatively correlating with emotional well-being scores in SZ, and not in HC. That is, SZ with younger appearing brains (predicted age < chronological age) had emotional summary scores that were more like HC, a relationship that endured after accounting for several demographic and clinical variables. ConclusionsThese data reveal clinically relevant aspects of brain age heterogeneity among SZ and point to case-control differences in the relationship between advanced brain aging and emotional well-being.

Hippocampal subfields, daily stressors, and resting cortisol in individuals at clinical high-risk for psychosis

IntroductionThe hippocampus, comprised of functionally distinct subfields, both regulates stress and is affected by it during psychosis pathogenesis. Hippocampal abnormalities are evident across psychosis spectrum and are associated with aberrant cortisol levels and greater environmental stressors exposure. These associations, particularly at the subfield-level, are poorly understood in individuals at clinical high-risk (CHR) for psychosis. This represents a significant literature gap given this critical pathogenetic period is characterized by an interplay between environmental stressors and biological susceptibility. MethodsA total of 121 participants including 51 CHR (mean age=18.61) and 70 healthy controls (HC; mean age=18.3) were enrolled in the study. Participants completed a structural scan, salivary cortisol assays, and a self-report measure assessing distress from daily stressors exposure (DSI). Hippocampal subfield segmentation was conducted using Freesurfer. ResultsSmaller hippocampal subfields were associated with greater stress levels. Greater DSI was associated with lower volumes in CA1 (r = −0.38) and CA2/3 (r = −0.29), but not in CA4/DG (r = −0.28), presubiculum (r = −0.09), or subiculum (r = −0.17). Higher resting cortisol was associated with lower volumes in presubiculum (r = −0.4) but not subiculum (r = −0.22), CA1 (r = 0.08), CA2/3 (r = 0.1), or CA4/DG (r = −0.005). Regressions indicated effects for CA1 and DSI (β = 0.57, p = .03) and presubiculum and cortisol (β = 0.61, p = .02) are specific to CHR participants relative to HCs. ConclusionsThe findings provided insights into links between stress and brain vulnerability during psychosis-risk period. Regional differences highlighted potentially different mechanisms by which stress impacts specific subfields. Presubiculum may be more susceptible to the impact of early stress on HPA-axis and cornu amonis to acute stressors.

The Impact Of Dating On Mental Health In Adolescents

Adolescents still do not realize that many Islamic teachings are established to protect their well-being and mental health. Dating, which is forbidden in Islam, has become more common among adolescents in recent days. Adolescents use love as the main reason for dating. This article aimed to examine the impact of dating on adolescents’ mental health. This study used a qualitative method with a phenomenological approach. Data was collected through observation and interviews with ten informants aged 19 to 22 (five informants had dated and the others did not). The study found that adolescents who have romantic relationships before marriage have greater stress levels than those who stay single. Prohibiting romantic relationships outside marriage is considered a form of Islamic teaching that safeguards human well-being.

Gender and Psychosocial Differences in Psychological Resilience among a Community of Older Adults during the COVID-19 Pandemic.

The study aimed at exploring gender and additional sociodemographic differences in psychological resilience, as well as the association between resilience and psychological distress in older adults, during the first lockdown in Italy, due to the COVID-19 pandemic. Participants attended an online survey during the first lockdown in May 2020. Psychological distress was assessed through the Depression Anxiety Stress Scale-21, the Resilience Scale (RS) was administered to evaluate psychological resilience, and sociodemographic variables were also collected. The study involved 108 community older adults (mean age 70.02 ± 3.5 years). Comparisons revealed that women reported significantly lower total scores of RS (p = 0.027), as well as lower levels of resilience-related domains, namely Meaningfulness (p = 0.049), Self-Reliance (p = 0.011), Perseverance (p = 0.035), and Existential Aloneness (p = 0.014), compared to men. Significantly higher RS scores were found in older adults being involved in a relationship, compared to those not involved in relationships (p = 0.026), and in older adults with children (p = 0.015), compared to those without offspring, suggesting the importance for older adults of not dealing alone with such a dramatic and stressful event, such as the pandemic. Negative correlations were found between psychological resilience and stress, depression, and anxiety. Linear regressions revealed that lower RS total scores, as well as lower scores in the majority of the RS scales, were associated with greater levels of stress, greater levels of anxiety, and greater levels of depressive symptoms. This study suggested that older women might appear more vulnerable in facing the pandemic, compared to men; having not lived alone through the lockdown period might also be considered as a factor of resilience for older adults.

College students' momentary stress and prescription drug misuse in daily life: Testing direct links and the moderating roles of global stress and coping.

Prior survey-based research has documented associations between greater levels of stress and increased prescription drug misuse behaviour. These studies uniformly rely on assessments of both the stress experiences and the substance behaviour after they occurred (commonly spanning 6-12month retrospective timeframes). Less is known about the extent to which variations in momentary stress predict the actual occurrence of prescription misuse in daily life among college students with elevated risk for engaging in the behaviour. In this study, 297 participants (69% females; Mage =19.5years, SDage =0.71) completed a 28-day ecological momentary assessment procedure that collected self-reported stress and other contextual experiences in moments preceding prescription drug misuse. Analyses tested the within-person association between momentary stress and prescription drug misuse and examined the extent to which the relation between stress and misuse was moderated by participants' assigned sex or global stress and coping levels. Results from hierarchical generalised linear modelling indicated a significant within-person association between momentary stress (i.e., higher than usual relative to one's own mean) and greater likelihood of prescription misuse in daily life, accounting for the number of stressors and timing covariates. No significant moderation by participant sex was found, and moderation effects by global stress and coping levels were not in the expected directions. Direct results highlight the role of momentary stress experiences on health-relevant substance behaviours and provide future directions for research and applied efforts.

Impacts of an extreme flood event on the riparian vegetation of a monsoonal cobble‐bed stream in southern Korea: A multiscale fluvial biogeomorphic framework

AbstractWith climate change increasing the magnitude and frequency of extreme precipitation events, there is a growing demand for investigations on the impacts of extreme flooding on the hydrological characteristics and vegetation of rivers, particularly in monsoonal areas. In this study, we examined multiscale relationships between hydrology, vegetation, and geomorphology after a record‐breaking flood event along the Seomjin River of South Korea in the summer of 2020. We conducted numerical modeling at the broad scale to identify the flow characteristics (e.g., depth and shear stress) of the flood event. A field survey was performed to investigate the impact of the flood on individual plants at the fine scale. The results showed widespread devastation of all vegetation types, from reed and willow communities to large, late‐successional trees taller than 10 m, which typically survive under ordinary flooding conditions. A higher threshold of shear stress was estimated for these trees (124 N m−2) than for willow (120 N m−2) and reed plants (26 N m−2), indicating that a greater level of stress is required to cause vegetation damage as ecological succession progresses. In the presence of vegetation, the average water depth increased by 9%–23% compared to the absence of vegetation. Many rivers in northeast Asia have undergone substantial vegetation expansion and succession due to the infrequency of extreme flood events. Our findings indicate that dense communities of large plants in these systems can raise the maximum water levels of flood events, thereby increasing the future flood risk to surrounding areas utilized for agriculture, transportation, industry, and housing.

The Toll of Technology while Working from Home during COVID-19

Drawing from a quota sample of adult Americans (N = 540), this survey explored how individuals who worked from home (WFH) during the COVID-19 pandemic used information communication technologies (ICTs), and the relationship use had with perceived stress. Results suggested that increased use of work-related video chat and text messaging were related to greater stress levels and that, in particular, women with multiple children experienced greater stress while working remotely. Theoretical and practical implications of the findings are discussed concerning remote work in the future.
