Frequency and clinical associations of common mental disorders in adults with high-grade glioma-A multicenter study.

One third of adults with cancer suffer from common mental disorders in addition to their malignant disease. However, it is unknown whether this proportion is the same in patients who have brain tumors and which factors modulate the risk for psychiatric comorbidity. In a multicenter study, patients with high-grade glioma at 13 neurooncology clinics were enrolled consecutively and interviewed with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (SCID) to diagnose common mental disorders. Predictors of psychiatric comorbidity were investigated using binary logistic regression. Six hundred ninety-one patients were interviewed. The proportion of patients who had mental disorders was 31% (95% confidence interval [CI], 28%-35%). There was evidence for an association of psychiatric comorbidity with the following factors: younger age (odds ratio [OR], 1.9; 95% CI, 1.1-3.4; p = .04), stable disease versus complete remission (OR, 1.7; 95% CI, 1.1-2.8; p = .04), lower income (OR, 1.7; 95% CI, 1.0-2.8; p = .04), living alone (OR, 1.6; 95% CI, 1.0-2.6; p = .05), fatigue (OR, 1.6; 95% CI, 1.1-2.4; p = .03), and impaired cognitive functioning (OR, 2.3; 95% CI, 1.5-3.6; p < .01). There was no evidence for independent effects of gender, histology, affected lobe, time since diagnosis, or employment status. Approximately one third of adult patients with high-grade glioma may suffer from a clinically relevant common mental disorder, without notable disparity between the genders. In particular, clinicians should pay attention to possible comorbidities for cases in which patients exhibit compromised subjective cognitive function, are younger than 50 years, maintain a state of stable disease, or live alone.

Technical Properties of the ClassMaps Survey

More than a decade after two comprehensive examinations of the technical properties of the ClassMaps Survey (CMS), this study reexamined the structure and internal consistency of the scale and, for the first time, examined its measurement invariance across gender and school levels. Participants were 1,083 elementary and middle level students from a diverse northeastern school district. Students had completed the CMS as part of their district’s evaluation of its bullying prevention program; the deidentified results were shared with researchers with approval of the district school board. Results of a seven-factor confirmatory factor analysis showed that all items loaded on their respective subscale, exhibited adequate model fit (CFI = 0.91; RMSEA = .04; SRMR = .07), and communicated good internal consistency (α = .78 to .92). Partial strong invariance was demonstrated across gender groups and school level groups. Gender effects, school level effects, and gender by school level interactions were demonstrated for some subscales. The collective results support the use of the CMS to support planning and refining classroom routines and practices that promote students’ classroom autonomy and effective relationships.

Predictive factors of extremity graft occlusion after endovascular repair of abdominal aortic aneurysm: A 13-year single center experience

Aim: Graft leg thrombosis (GLT) after Endovascular Aortic Repair (EVAR) is an important problem affecting morbidity/mortality. In addition to anatomical factors such as aortic neck angle and diameter in graft leg thrombosis; we aimed to convey the roles of graft extension to the external iliac artery and the effect of graft type selection on the results. Material and Methods: Analysis of 512 patients who underwent EVAR between 2010 and 2023 was performed. The effects of anatomical factors, graft material, underlying diseases, age and gender on the development of graft leg thrombosis were evaluated. Anatomical measurements were evaluated in terms of their predictive power for graft leg thrombosis by Receiver Operating Characteristic (ROC) analysis. Results: The prevalence of graft leg occlusion was significantly associated with some anatomical factors, especially increased aortic neck angle (OR=1.07, p&lt;0.001) and descent to the external iliac artery (OR=13.43, p&lt;0.001). Poliytetrafluoroethylene (PTFE) grafts were associated with a reduced risk of graft leg occlusion (OR=0.26, p=0.002). ROC analysis showed that aortic neck angle had the highest predictive accuracy for GLT (AUC=0.817, p&lt;0.001). There were no significant differences in age, gender, smoking status, diabetes, and hypertension as comorbidities. Peripheral artery disease was shown to increase the risk. Conclusion: Our findings highlight the role of aortic anatomy and graft material selection in the risk of graft leg thrombosis. The use of PTFE grafts appears to be protective against graft leg thrombosis. This information highlights the importance of personalized surgical planning and postoperative management to optimize patient outcomes. Future research should focus on developing models that include these factors.

Gender differences in perioperative complications following carotid endarterectomy: A retrospective analysis

Aim: This study aims to examine the distribution of major complications in patients undergoing carotid endarterectomy (CEA) based on gender. The primary objective is to assess the potential effects of gender on perioperative events in hospital. Material and Methods: At Başakşehir Çam and Sakura City Hospital, patients aged 18 and over who underwent CEA between September 2020 and November 2023, were retrospectively analyzed. The patients were categorized into two groups based on their gender. Patient characteristics were obtained from electronic medical records. Postoperative stroke, surgical revision, hematoma, and nerve injury were defined as perioperative events. Results: In this study, the average age of the 225 evaluated patients was found to be 65.8 ± 8.89. There were 73 female patients (32.44%) in Group 1 and 152 male patients (67.56%) in Group 2. Two patients (0.9%) experienced a stroke during the perioperative period. Hematomas were present in 24 patients (10.7%), and nerve damage was also observed in 15 patients (6.7%). Surgical revision due to bleeding was required in thirteen patients (5.8%). Perioperative events were observed in 27 patients. Perioperative events were significantly higher in men than in women (p=0.037). In multivariate logistic regression analysis, male gender was found to be the predictor of perioperative events (odds ratio [OR]: 3.701;95% CI: 1.145-11.963, p=0.029). Conclusion: Our results showed that male gender may be a predictor of perioperative events in patients undergoing carotid endarterectomy. Multicenter and larger study groups may be needed for healthier results.

Predicting THE Determinants of Mobile TV Adoption in an Emerging Market: Moderating Effect of Gender and Age

This article focuses on the impact of consumer-centric factors on the adoption of mobile TV in an emerging market, considering the widespread use of mobile technologies worldwide. It aims to explore the motivations behind users’ utilization of mobile TV and over-the-top platforms in the era of digitalization. The study identifies eight independent factors affecting mobile TV adoption intention, grouped using a three-dimensional THE (technology, human, and environment) framework. Data was collected from 324 smartphone users to test the hypothesized relationships using covariance based structural equation modeling (CB-SEM) analysis. Further, moderating effect of gender and age was studied on the proposed relationships. The findings revealed that factors such as cost, content, perceived enjoyment, individual viewing experience, social influence, and convenience play a significant role in the successful adoption of mobile TV. On the other hand, app switching and technology readiness were found to be statistically insignificant. The results offer valuable insights to industry players regarding consumers’ adoption behaviour of mobile TV, helping them minimize business risks and focus their efforts, resources, and investments on profitable innovations. The study is first of its kind in India and adds two relatively new factors, that is individual viewing experience and app-switching, to the existing literature on technology adoption theories.

An Empirical Study of the Constituent Factors of Player Behaviour

Background Player behaviour comprises thoughts, decisions and other actions that arise from multiple sources and contexts in games and is based on the players’ complex environment of information, vicarious experiences and perspectives. Learning and superior performance within the game are shaped by the players’ goal orientation, conviction and interactions. Objectives of the study: The study sought to understand the concept, functions and constituents of player behaviour from their perspectives, expectations, beliefs and traits. Recognising player behaviour in terms of its constituent elements would clarify and enhance knowledge of human behaviour and make it simple to use the understanding in deeper enquiry and applications. Method An instrument of 43 statements was first developed based on extant research and refined by the responses of 45 university teachers. It was then administered to 1,260 university students from whom 711 valid responses were received. The sample was processed by exploratory factor analysis under varimax rotation to yield the scale of player behaviour at a Cronbach alpha of .96 and a cumulative variance of 54 percent. Results The seven factors of the scale had an eigenvalue each of more than one, and Cronbach α values of .58 to .90. The exploratory factor analysis generated seven factors that were named conviction, experience sharing, uncertainty, unpredictability, insights, preparedness and planning. Discussion The study identified the factors of player behaviour and studied the effect of gender and education on player behaviour. It showed that player behaviour emerges from convictions which are perspectives backed by ready resources, skills and action plans to simplify, understand and respond to situations and likely problems. The behavioural differences between gender, type of programme and level of education were not significant. The study also discussed the nature of each factor and the limitations, suggestions and implications of the study.

Gender variability in palpation performance for temporomandibular disorders with three different methods: An experimental study.

Gender differences in pain reporting and prevalence have been demonstrated. As gender of examiner also affects reporting of pain on palpation, the aim of this study was to evaluate the effects of examiner gender on palpation performance using three different palpation methods. Examiners of both genders were instructed on the correct technique for each palpation method by either a female or male instructor. The target was to achieve a pressure of 100kPa, corresponding tothe 1kg of force for muscle palpation described in the diagnostic criteria for temporomandibular disorders (DC/TMD). All examiners performed traditional palpation with the index finger, palpation with a palpometer, and a novel bimanual palpation with visual feedback, in a randomized order. The examiner's gender, and its interaction with the gender of the instructor did not significantly affect magnitude, accuracy, or precision of the pressure applied. The method of palpation was the only factor that significantly impacted all metrics. The palpometer achieved the lowest palpation magnitude (mean pressure applied=113.7kPa, 95% CI: 109.8-117.6), the highest accuracy (absolute difference=15.7kPa, 95% CI: 12.3-19.1), and the highest precision (mean coefficient of variation=6.8, 95% CI: 6.0-7.6), followed by bimanual palpation and traditional palpation. The results suggest that gender differences in pain reporting in patients are not likely to be a result of the technical aspects associated with the gender of the examiner. Instead, these differences may be attributed to other factors, such as sociocultural influences.

Differential Gender Effect of Technical and Vocational Education Students’ Human Capital on Long-term Economic Growth in Nigeria

From a gender view point, this study examines the relationship between the human capital of technical and vocational education students and the fundamental principles of long-term economic growth in Nigeria. The study used a correlational survey research approach. The study was directed by four research questions, and four null hypotheses were developed. The population for the study consisted of all 400 level undergraduate students (N = 286) of technical and vocational education in Federal and State-owned Universities in South-South geopolitical zone of Nigeria. The population was of a manageable size, thus there was no sampling. Data was gathered via a questionnaire. Three research experts- two from Ambrose Alli University in Ekpoma, the Department of Vocational and Technical Education, and one from the Measurement and Evaluation University of Benin in Benin City, Edo State validated the instrument. The instrument's dependability was assessed using Cronbach alpha reliability, and a reliability coefficient of 0.85 was found. In order to address these inquiries, bivariate correlation was utilized. Multiple regression analysis and analysis of variance were used to examine the hypotheses. The results showed that, fundamental values and both general and particular human capital were positively correlated long-term growth. Students in technical and vocational education, whether male and female, encounter nearly the same kinds of human capital overall. Keywords: Technical and vocational education, Differential gender effect, Human capital, Long-term economic growth.

Evaluation of Alveolar Bone Destruction Patterns in the Posterior Region of the Maxilla Through Cone Beam Computer Tomography on 361 Consecutive Patients: Effect of Age and Gender.

The aim of this retrospective study is to evaluate the effect of age and gender on the alveolar bone destruction pattern with cone beam computed tomography (CBCT) in the posterior region of the maxilla. The study group included CBCT image records of 361 consecutive patients (180 males and 181 females) aged 20 years and older. Alveolar crest morphology in the maxillary right and left first and second molar teeth on retrospective images was classified as a horizontal or vertical defect (one-walled, two-walled, three-walled, and combined bone defect) on four surfaces (mesial, distal, buccal, and palatinal). Bone crater defects were defined, and furcation involvements and combined periodontal-endodontic lesions (CPELs) were placed in another category. In 361 patients, 1444 teeth were evaluated from adults between 20 and 63 years of age; 49.9% of the patients were male and 50.1% were female. Female patients had a considerably greater rate of one-walled horizontal damage in the right molar teeth than male patients (p = 0.002; p < 0.05). Patients with combined horizontal destruction in the right and left molar teeth, horizontal destruction in the palatinal, and horizontal three-walled destruction had a significantly higher mean age than patients without these periodontal destructions (p = 0.000; p < 0.05). Males were shown to have statistically higher frequencies of horizontal defects when defects were combined or distally and palatally located. Age and gender affect the alveolar bone loss pattern. Except for single-walled destructions, it has been found that the frequency of horizontal destruction increases with age. Horizontal destruction in the palatinal along with horizontal three-walled destruction increased with age.

Agreement of intraocular pressure measurement by scleral Schiotz and Goldmann applanation tonometer.

In this cross-sectional observational study, IOP was measured by GAT on the cornea and Schiotz tonometer on the temporal sclera. Axial length and central corneal thickness (CCT) were noted. IOP was then estimated from SS IOP as eGAT using a predictive formula. Agreement of IOP corrected for CCT (cGAT) with eGAT and SS IOP were assessed. The effects of age, axial length, refraction, CCT, gender, and ocular and systemic comorbidity on measured IOP were also assessed. The study included 155 patients with a mean age of 54.27 ± 10.02 years. Mean IOP measured by GAT and scleral Schiotz were 16.58 ± 2.76mm Hg and 16.10 ± 2.96mm Hg, respectively. The mean IOP by cGAT and eGAT were 16.70 ± 2.80mm Hg and 17.07 ± 3.10mm Hg, respectively. Both eGAT & SS IOP had good agreement with cGAT on the Bland-Altmann plot (p = 0.96 & 0.51, respectively). Further, SS IOP showed good agreement even with GAT IOP (p = 0.78). Age, axial length, refraction, central corneal thickness, gender, and ocular and systemic comorbidity did not show significant correlation with IOP measurement. Estimated GAT IOP showed good agreement with measured GAT values. SS IOP also agreed well with GAT IOP. Clinical significance IOP measurement on the sclera using Schiotz can be used as an alternative to GAT.

Exploring the Relationship between Masseter and Cervical Vestibular-Evoked Myogenic Potentials in Young Adults with Hearing Thresholds Less Than or Equal to 15 dB HL.

Cervical vestibular-evoked myogenic potentials (cVEMPs) and masseter vestibular-evoked myogenic potentials (mVEMPs) are considered to have a common saccular origin. While a few studies have examined both vestibular-evoked myogenic potentials (VEMPs) in individuals with brainstem disorders as part of a test battery, the relation between these two potentials has rarely been the subject of discussion. The present study explored the relation between mVEMPs and cVEMPs using electromyography (EMG)-scaled parameters in normal-hearing young adults. Within-subject study design. Twenty young adults between 18 and 39 years of age (11 males, 9 females) participated in the study. cVEMP and mVEMP were performed on all the participants at 95 dBnHL with 500 Hz tone burst stimuli. Various VEMP parameters were evaluated including P13 and N23 peak latencies, the amplitude of the P13-N23 complex, and the Interaural Amplitude Asymmetry Ratio in EMG-scaled and unscaled conditions. All participants exhibited a 100% response rate for cVEMP and mVEMP responses. There were no significant ears and gender effect for both cVEMP and mVEMP. No correlation was found between cVEMP and mVEMP. There was no significant difference found between P1 and N1 latency values of cVEMP and mVEMP; however, a significant variation was observed for peak-to-peak amplitude both in EMG-scaled and unscaled conditions between cVEMP and mVEMP. Minimal to no association between any parameters of cVEMPs and mVEMPs suggests no significant relationship between these two VEMPs.

Humour in trolley problems and other sacrificial dilemmas: killing is not funny at all

ABSTRACT Three studies were designed to explore a major criticism of sacrificial dilemmas, namely that their potential humorous aspects may distort moral decision-making. We collected moral responses (i.e. moral judgment and choice of action) but also asked participants to rate the funniness of moral dilemmas, in order to combine humour assessment and moral responses. In addition, the emotional responses to moral dilemmas were recorded for both men and women (including emotions related to humour), and the potential effect of individuals’ need for humour was also considered. Overall, three main results were reported. Firstly, the dilemmas used in our studies were not rated as funny at all. Secondly, reading moral dilemmas increased negative emotions (i.e. sadness, disgust, guilt) and decreased positive emotions associated with humour (i.e. joy, amusement, and mirth), with gender effects since women experienced stronger negative emotions than men. Thirdly, funniness ratings of sacrificial dilemmas did not vary according to gender and need for humour. This series of studies does not report empirical evidence to support the humorous aspects of trolley-type dilemmas, but invites a more systematic examination of how sacrificial dilemmas are perceived by participants who have to produce moral responses.

Relationship between Chinese college students’ attitude to physical exercise and psychological capital: the mediating effects of self-control and gender

ObjectiveThis study aimed to explore the impact of attitudes toward physical exercise on college students’ psychological capital and its mechanism of action, providing new pathways and scientific evidence for enhancing psychological capital among college students.MethodsA total of 519 college students (mean age: 19.95 ± 1.34) were surveyed using a questionnaire.Results(1) Attitudes toward physical exercise have a significant direct predictive effect on college students’ psychological capital; (2) Attitudes toward physical exercise can indirectly predict psychological capital through the mediating role of self-control; (3) The influence of attitudes toward physical exercise on self-control is moderated by gender, with a greater impact on female college students than on male students.Conclusion(1) This study investigated the mechanism by which attitudes toward physical exercise influence psychological capital through self-control and gender differences; (2) The study revealed the positive role of psychological capital, with a significant predictive effect of attitudes toward physical exercise on college students’ psychological capital (B = 0.46, p &amp;lt; 0.001), and identified the reasons for gender differences, with attitudes toward physical exercise having a stronger promoting effect on self-control in female college students (B = 0.26, t = 3.80, p &amp;lt; 0.001). It provides guiding suggestions for enhancing psychological capital by fostering attitudes toward physical exercise among college students.

COVID-19 mental health impacts on academic engagement: a study on students of Egypt and India

Purpose This study aims to investigate the association between COVID-19-related fear and academic engagement, perceived stress and life satisfaction among college students in two countries – Egypt in Africa and India in Asia, during the pandemic. The study also aims to analyze the moderating role of gender in these relationships. Design/methodology/approach Structural equation modeling was used to analyze data collected from 1,125 college students from India and 1,145 college students from Egypt. Findings Positive correlations were found between fear of COVID-19 and perceived stress among the college students of Egypt and India, while negative correlations were found between fear of COVID-19 and both student engagement and life satisfaction. The strength of these relationships was found to be stronger in the Egyptian sample compared to the Indian sample. Gender was found to be a significant factor in the relationships between the variables studied. In the Indian sample, female respondents appeared to experience more mental health concerns and academic impacts than male respondents. In the Egyptian sample, however, the gender effects varied for the different relationships between the fear of COVID-19 and the other chosen variables. Originality/value The results emphasize the need to reevaluate and monitor policies and resources to promote positive mental health among adolescents, especially during times of crisis. The study stands among the pioneers that investigated a comparative study of two countries to check the mental health impacts on the study engagement during the pandemic.

Effects of School-led Greenspace Interventions on Mental, Physical and Social Wellbeing in Children and Adolescents: A Systematic Review

AbstractPromoting children’s and adolescents’ mental, physical, and social wellbeing is highly important to help them learn, create social connections, and stay healthy. Nature has the potential to restore cognition, reduce stress and mental fatigue, and improve wellbeing, all factors that are conducive to learning. There is growing interest in understanding the effects of nature on the wellbeing of children and adolescents, particularly in the school context. This paper presents a PRISMA-guided systematic review of the literature examining the effects of school-led nature interventions on the mental, physical, and social wellbeing of school children and adolescents aged 5 to 19 years. Examples of school-led nature interventions include outdoor learning, walks in nature and green schoolyards. Experimental and quasi-experimental studies employing quantitative measures were selected, yielding 19 studies from 17 papers. Included studies were rated as being of high (n = 6) and moderate quality (n = 13). The results provide some evidence that nature exposure in the school context can improve the wellbeing of children and adolescents, particularly their positive affect, physical activity, and social relationships/interactions. The wellbeing effects of school-led nature interventions were also examined according to age and gender, with results indicating a gender effect, but inconclusive findings for age. Findings from this review support the integration of nature in schools to enhance the mental, physical and social wellbeing of children and adolescents.

Emotional resilience and sense of danger among doctors in hospitals during periods of heightened tensions and warfare in Israel.

The "Iron Swords" War beginning in October 2023 led to unprecedented levels of shock and trauma across Israel, significantly impacting the Israeli population and medical personnel. This study aimed to evaluate and compare the perceived personal resilience and sense of danger among physicians in hospitals located in different conflict zone proximities in Israel during this period. A quantitative, cross-sectional study was conducted from March to August 2024, during an active phase of the war, using a structured anonymous questionnaire. Participants were 161 physicians from three hospitals: one in southern Israel near the Gaza Strip, another in northern Israel near the borders with Lebanon, Syria, and Jordan, and a third in central Israel near Tel Aviv. The survey measured personal resilience using the Connor-Davidson Resilience Scale (CD-RISC-10) and sense of danger using the Solomon & Prager scale. Statistical analyses included Kruskal-Wallis H test, multiple linear regression, two-way analysis of variance (ANOVA), and Sobel test for mediation effects. The final sample included 161 physicians (54 southern, 56 central, 51 northern). The mean resilience score was 31.14 ± 5.77, and the mean sense of danger score was 8.36 ± 4.15 (scales 0-40 and 0-20, respectively). Physicians in the southern hospital reported significantly higher sense of danger scores (p = 0.005). A trend towards lower resilience scores was noted among southern hospital physicians (p = 0.068) (p = 0.068). Two-way ANOVA revealed significant main effects of hospital location and gender on resilience (p = 0.046 and p = 0.003, respectively) and sense of danger (p = 0.005 and p = 0.062, respectively). Multiple regression analysis identified hospital location (β = -0.178, p = 0.023) and gender (β = 0.229, p = 0.004) as significant predictors of resilience. Mediation analysis indicated that personal resilience partially mediated the relationship between hospital location and sense of danger (indirect effect = 0.2896, p < 0.001). Physicians working near conflict zones report higher levels of perceived danger, though their resilience is comparable to peers in less threatened regions. Enhancing personal resilience is crucial to mitigate the heightened sense of danger. This could include regular resilience training, psychological support, and specific programs for single and childless physicians to improve safety perceptions. Additionally, fostering a supportive community with clear communication and robust emergency protocols is essential for enhancing staff resilience and safety in hospitals.

Gender Stereotyping in Robot Service Failures

AI agents, such as service robots, could encompass gender cues. However, little is known regarding whether and how customers apply gender stereotyping to service failures in gendered service tasks performed by robots. Drawing on gender stereotype theory, we investigate the joint effects of robot gender (feminine vs. masculine) and task type (female-dominated vs. male-dominated) on customer dissatisfaction following service failures. Study 1 reveals that feminine service robots are perceived as more communal but as equally agentic as their masculine counterparts. Study 2 demonstrates that feminine (vs. masculine) service robots generate lower customer dissatisfaction when failing a female-dominated task. However, this discrepancy diminishes when failures occur in a male-dominated task. Perceived communion and tolerance serially mediate such robot gender effects. Our findings suggest that using feminine robots across all service categories may be a cost-effective strategy for hospitality organizations, eliminating the need to vary robot gender by task type.

Association between sleep quality, sleep duration, and physical frailty among adults aged 50 years and older in India.

Considering the significant growth in India's aging population, it is imperative to identify factors associated with frailty among older Indians. This study examined the association between sleep quality, sleep duration, and physical frailty among older adults in India. Moreover, we examined whether the associations between sleep quality, sleep duration, and physical frailty varied by gender. In this secondary analysis, we used data from the 2015 wave 2 of the Study on Global Aging and Adult Health (WHO-SAGE) in India, comprising a sample of 6,512 older adults aged 50 years and above. Pre-frailty and frailty were assessed using the modified version of the frailty phenotype developed by Fried and colleagues. Sleep was assessed by self-reported quality and duration. Multinomial and multivariable logistic regression models were used to examine the associations between sleep quality, sleep duration, and physical frailty (including its components), as well as to explore the moderating effect of gender. 66.8% of older Indians were pre-frail, while 25.2% were frail. Relative to those with good sleep quality, older adults with poor sleep quality had significantly higher odds of frailty [AOR: 2.79; CI: 1.37-5.66]. Compared to those receiving the recommended age-appropriate 7-8h of sleep, older adults sleeping ≥ 9h reported a significantly lower likelihood of both pre-frailty [AOR: 0.73; CI: 0.57-0.93] and frailty [AOR: 0.68; CI: 0.51-0.91]. Analysis of specific components of frailty showed that older adults with long sleep had lower odds of exhaustion [AOR: 0.86; CI: 0.73-1.00] compared to those with age-appropriate sleep duration. Moreover, frailty was more pronounced in older men with poor sleep quality and short sleep duration (< 7h/night) than in older women with similar sleep patterns. Poor sleep quality was not linked to any of the frailty components in older women; however, in older men, it was associated with exhaustion [AOR: 4.28; CI: 2.28-8.06], weak grip strength [AOR: 2.31; CI: 1.46-3.67], and low physical activity [AOR: 2.81; CI: 1.10-7.21]. The findings indicate potential associations between sleep quality, sleep quantity, and physical frailty among older Indians. Poor sleep quality was associated with frailty, yet long sleep duration was associated with a lower prevalence of frailty, independent of sleep quality. Moreover, the prevalence of frailty associated with poor sleep quality and shorter sleep duration was more pronounced among older Indian men than women, underscoring the need for targeted interventions to address sleep-related concerns in this demographic.

Competence Perceptions at the Intersection of Gender and Race-Ethnicity

Competence perceptions represent a fundamental dimension of human perception and have wide-ranging consequences for social interaction. Therefore, it is no surprise that multiple prominent social psychological theories emphasize the role of competence perceptions. We know that both a person’s gender and race-ethnicity influence assumptions about their competence, but we have only a few studies examining the intersections of these factors. Using a large survey experiment (N = 1,219), I examine competence perceptions at the intersection of 2 gender and 13 racial-ethnic categories. Results show large effects of both gender and race-ethnicity and also highly intersectional stereotypes; that is, there is no one overarching effect of gender or race-ethnicity but instead contingent effects. By oversampling racial-ethnic minorities, I also test the assumption of consensus for competence perceptions. Results show highly consensual perceptions, suggesting we all recognize society’s stereotypes even if we do not agree with them.

Uncovering the nonlinear relationship between metacognitive strategy use and L2 achievement from the lens of the Island Ridge Curve: more is not always better

Metacognitive strategies are essential to second/foreign language (L2) acquisition. However, the individualized use of metacognitive strategies and their relation to L2 learning has been understudied. Guided by the theory of the Island Ridge Curve (IRC), the current study used latent profile analysis (LPA) to explore university students’ unique patterns of metacognitive strategy use during L2 (English) acquisition. A total of 1180 undergraduates (freshmen and sophomores) participated in this study. Results of LPA revealed four profiles of strategy use: low, medium, high, and extremely high strategy profiles. Multinomial regression analysis indicated no significant effect of gender on the four strategy profiles but a significant negative effect of grade level on the extremely high strategy profile, meaning second-year students are less likely to overuse metacognitive strategies than first-year students. An analysis of variance showed that students’ English achievement increased steadily from the low to the extremely high profile. However, a post hoc analysis indicated that the change in English achievement from the high to the extremely high strategy profile was non-significant. This nonlinear relationship provides further evidence reinforcing the fluid relationship between metacognitive strategies and English achievement. More importantly, this study validates the IRC theory in the context of L2 acquisition.
