Generative AI has rapidly entered college writing classrooms, raising practical questions about how student texts are changing and what that means for instruction. This study analyzes 255 final-draft analytical essays written in first-year writing classes across three instructional contexts—pre-Gen-AI (Winter/Spring 2022), AI-prohibited, and AI-permitted with specified uses (Winter/Spring 2024). We combined holistic quality ratings of essays with Coh-Metrix indices of writing volume, lexicality, referential cohesion, and syntax. Analytically, we estimated a regression of essay quality on class type and demographics, and MANCOVAs (with essay score and demographics as covariates) for the four linguistic constructs. Essay quality did not differ by AI policy. However, compared to 2022, essays of AI-permitted classes were organized into fewer but shorter paragraphs; displayed greater lexical diversity and used less frequent, less familiar vocabulary; showed lower local and global anaphor overlap (other cohesion indices were stable); and exhibited lower verb-phrase, passive, and negation densities but higher gerund density. We interpret these as selective redistributions of linguistic resources rather than uniform gains or losses. For instructors, the actionable implication is two-fold: leverage AI-era gains in lexical precision while explicitly teaching referential continuity and clause-level strategies that sustain argumentative coherence.

This study examined whether the systems thinking approach integrating information and communication technology (ICT) and digital tools (hereafter referred to as the STICT approach) improves technological and engineering literacy (TEL) and related outcomes for pre-service preschool teachers. Although there is an expectation for preschool teachers to develop TEL, evidence-based models that systematically combine systems thinking with digital tools and ICT support remain scarce. Using a quasi-experimental design (n = 44; one-semester experiment), the experimental group explicitly integrated systems thinking and digital tools, while the comparison control group followed the traditional approach to teaching design, technology, and engineering (DTE) content; both groups focused on making products for preschoolers. The outcomes included multidimensional literacy, attitudes towards DTE, self-reported systems thinking, aspects of engagement, and focus group reflection. The analyses (ANCOVA/MANCOVA, regression/PLS, multi-group tests, thematic analysis) revealed notable results, including a higher post-test literacy for the experimental group and a lower perceived difficulty with technology. Both groups improved in the self-assessment of systems thinking, with no differences between them. The qualitative findings supported the educational value of the approach. In this pilot classroom experiment (n = 44), findings are consistent with an advantage of the STICT approach on the TEL composite and with lower perceived difficulty of technology, whereas self-assessed systems thinking improved similarly in both groups. Given the small sample and multiple outcomes, estimates carry considerable uncertainty and should be read as preliminary. We theorise that TEL gains arise primarily from systems thinking processes applied during design/evaluation, with ICT functioning as a cognitive-and-motivational scaffold that makes relations/feedback explicit and reduces perceived difficulty; self-assessed systems thinking improved in both groups.

Background: This study examined nutritional intake, body composition, menstrual health, and performance in elite female trail runners. Methods: A cross-sectional multivariate analysis was conducted on 35 athletes (14 eumenorrheic, 21 amenorrheic/oligomenorrheic). Nutritional intake was assessed through 7-day and 24 h food records; anthropometry followed ISAK standards; performance was evaluated via ITRA and UTMB rankings. Statistical analyses included t-tests, MANCOVA, regression models, and Random Forest, adjusting for body composition and covariates. Results: Although energy availability (EA) did not differ significantly between groups, 94.3% of athletes had clinically low EA (<30 kcal/kg FFM/day). Amenorrheic athletes consumed more simple carbohydrates (21.8 ± 5.7% vs. 17.2 ± 3.1%), protein (2.5 ± 0.6 vs. 1.7 ± 0.2 g/kg/day), fiber, and lipids, while eumenorrheic athletes consumed more complex carbohydrates (129.7 ± 27.0 vs. 82.5 ± 33.3 g/day) and most vitamins. Both groups had inadequate calcium and iron intake. Low EA was moderately associated with an ectomorphic somatotype (r = 0.418). Performance negatively correlated with simple carbohydrates (r = −0.624) and positively with complex carbohydrates, total energy, protein, polyunsaturated fats, and zinc (r = 0.300–0.580). No significant performance differences were found between menstrual status groups. Conclusions: Menstrual irregularities did not affect performance, but nutritional patterns strongly influenced both performance and energy availability. Personalized nutrition strategies are essential for optimizing performance and safeguarding health in elite female trail runners. Full article

Prenylated flavonoids from hops (Humulus lupulus L.) represent a distinctive class of bioactive compounds with notable antioxidant and health-promoting properties. This study investigated the extraction behavior and quantitative profiles of three major prenylflavonoids—xanthohumol (XN), isoxanthohumol (IXN), and 8-prenylnaringenin (8-PN)—under varying solvent polarity (ethanol vs. methanol), extraction temperature (50–200 °C), and sample pretreatment (mechanical vs. cryogenic homogenization). Extractions were performed using accelerated solvent extraction (ASE), and compounds were quantified by HPLC-DAD. Ethanol exhibited higher extraction efficiency than methanol, while cryogenic pretreatment markedly enhanced the release of all target analytes. The maximum recovery was achieved at 150 °C for XN, 200 °C for IXN, and 100 °C for 8-PN. Multifactor statistical analysis (MANCOVA, ANOVA) confirmed significant effects of solvent, temperature, and pretreatment, as well as their interactions (p < 0.001). The combination of ASE and cryogenic homogenization enables efficient isolation and precise quantification of prenylated flavonoids from hops, providing a valuable analytical framework for the development of standardized hop extracts and bioactive formulations.

Rapid advances in artificial intelligence (AI) are reshaping curricula and work, yet technology and engineering education lack a coherent, critical AI literacy pathway. In this study, we (1) mapped dominant themes and intellectual bases and (2) compared AI literacy between secondary technical students and pre-service technology and engineering teachers to inform curriculum design. Moreover, we conducted a Web of Science bibliometric analysis (2015–2025) and derived a four-pillar framework (Foundational Knowledge, Critical Appraisal, Participatory Design, and Pedagogical Integration) of themes consolidated around GenAI/LLMs and ethics, with strong growth (1259 documents, 587 sources). Phase 2 was a cross-sectional field study (n = 145; secondary n = 77, higher education n = 68) using the AI literacy test. ANOVA showed higher total scores for pre-service teachers than secondary technical students (p = 0.02) and a sex effect favoring males (p = 0.01), with no interaction. MANCOVA found no multivariate group differences across 14 competencies, but univariate advantages for pre-service technology teachers were found in understanding intelligence (p = 0.002) and programmability (p = 0.045); critical AI literacy composites did not differ by group, while males outperformed females in interdisciplinarity and ethics. We conclude that structured, performance-based curricula aligned to the framework—emphasizing data practices, ethics/governance, and human–AI design—are needed in both sectors, alongside measures to close gender gaps.

(1) Background: Physical inactivity is a major public health concern in modern society. Group fitness programs are widely used to promote physical activity, combining choreographed movements with various dance steps and music. This study aimed to examine the effects of Zumba and MoFit group fitness programs on body composition parameters in women. (2) Methods: The study included 98 female participants (Mean age = 27.8 ± 2.9 years), divided into three groups: E1 (n = 33), which followed the experimental Zumba program; E2 (n = 31), which followed the experimental MoFit program; and a control group (n = 34), which continued with their usual daily activities for 10 weeks. Body composition was assessed using 14 variables measured with the InBody 270 analyser. Statistical analyses included paired t-tests, MANCOVA, and ANCOVA. (3) Results: The findings confirmed the positive effects of both group fitness programs on most body composition parameters in women (p < 0.001). However, Bonferroni post hoc test results indicated that the Zumba program led to significantly greater improvements in most body composition variables compared to the MoFit program. (4) Conclusions: Both Zumba and MoFit programs were effective in reducing body fat, increasing muscle mass, total body water, and mineral content, whereas the control group did not achieve positive changes.

Background: Motor coordination is a fundamental skill in childhood. Factors such as age, sex, and regular sports practice influence its development. However, there is little research that jointly analyzes the impact of these factors on the motor skills and abilities of primary school children. The objective of this study was to analyze what happens to different motor skills and abilities (i.e., locomotor coordination (LC); visuomotor coordination (VC); foot object control coordination (FOCC); hand object control coordination (HOCC); global motor coordination (GMC)) in relation to regular and regulated sports practice (yes vs. no), sex (boys vs. girls), and age (6 to 11 years) in a sample of 663 primary schoolchildren (8.59 ± 1.65 years; 48.26% boys) from Galicia (Spain). Methods: The 3JS test was used to analyze motor coordination. To determine differences between the 3JS variables, a multivariate analysis of covariance (MANCOVA) was performed based on age, sex, and sports practice, including a BMI category (normal weight, overweight, or obese) as a covariate to avoid potential confounding factors. Results: Statistically significant differences were observed based on age [LC (p < 0.001); VC (p < 0.001); FOCC (p < 0.001); HOCC (p < 0.001); CMG (p < 0.001)], sex [i.e., VC (p < 0.001); FOCC (p < 0.001); HOCC (p < 0.001); CMG (p < 0.001)], and sports practice [i.e., LC (p < 0.001); VC (p = 0.008); HOCC (p < 0.001); CMG (p < 0.001)], after the application of the 3JS battery. Conclusions: Locomotor coordination in Primary Education is modulated by the interaction between age, sex, and sports practice. All of these variables increase with age, with higher scores in boys than in girls, and higher scores in children who participate in sports than in those who do not. Full article

Background/Objectives: In the context of active ageing, functional assessment is key to preserving autonomy in older women. The six-minute walk test (6MWT) is a practical tool for estimating general health, but its results can be influenced by various factors. This study analysed cardiorespiratory variations during the 6MWT in older women according to their physical activity level and age-related variables such as pain, sarcopenia, frailty, and motivation to exercise. Methods: A total of 163 older women with musculoskeletal pain, but without cardiac or respiratory conditions, were classified into groups with high (HPA), moderate (MPA), and low (LPA) physical activity. During the 6MWT, heart rate (HR), dyspnoea, and oxygen saturation (SpO₂) were recorded. Pain, sarcopenia, frailty, and motivation to exercise were also assessed. A repeated-measures multivariate analysis of (co)variance (RM-MANCOVA) was performed. Results: The results showed differences in HR depending on the level of physical activity, conditioned by sarcopenia (p < 0.05) and walked distance (p < 0.001), and in dyspnoea conditioned by pain perception (p < 0.01) and social (p < 0.001) and psychological (p < 0.05) motivation to exercise. There were also differences in SpO₂ depending on the level of physical activity (p < 0.0001). There were differences between the HPA group and both the MPA and LPA group, which had higher HR, higher dyspnoea, and lower SpO₂ when undergoing the 6MWT test. Conclusions: To accurately interpret 6MWT results in older adult women, it is essential to consider physical activity level, perceived pain, sarcopenia, and motivation to exercise, as these factors influence HR, dyspnoea, and SpO₂. These variables should guide physical activity recommendations for healthy ageing. Full article

Objectives: (1) To compare cytokine levels in participants with serum urate (SU) < 360 µmol/L, SU ≥ 360 µmol/L with and without monosodium urate (MSU) crystal deposition, respectively, and inter-critical gout. (2) To explore the association of IL-1β, IL-6 and high-sensitivity (hs) CRP with disease duration and the frequency of self-reported gout flares. Methods: Samples and data from 184 participants from studies conducted at Academic Rheumatology, Nottingham City Hospital, were included. Serum high-sensitivity CRP and cytokines involved in the pathogenesis of gouty inflammation were measured. MANCOVA and multivariate linear regression were used, as appropriate, and were adjusted for age, sex, body mass index and self-reported comorbidities. p values were adjusted for multiple testing using a 5% false-discovery rate. Results: Participants with inter-critical gout had greater levels of IL-1β (p_corr = 0.009), IL-18 (p_corr = 0.02), IL-6 (p_corr < 0.0001), IP-10 (p_corr < 0.0001), TNF-α (p_corr < 0.0001), GRO-α (p_corr = 0.0006) and hsCRP (p_corr = 0.009) compared to other groups in multivariate analyses and after correcting for multiple testing. There were no differences in cytokine and hsCRP levels in participants with SU < 360 µmol/L and in participants with SU ≥ 360 µmol/L with or without MSU crystal deposition. There was a statistically non-significant trend for association between IL-6 levels and number of self-reported gout flares. Conclusions: Our findings suggest that gout is a chronic inflammatory condition. The pre-clinical phases of gout were not associated with systemic inflammation, potentially due to the modest sample size. Further research is required to understand whether treating gout by targeting the complete dissolution of MSU crystals would reduce systemic inflammation in inter-critical gout. Full article

Background: Patients diagnosed with coronary artery disease (CAD) have been seen to exhibit increases in health-related quality of life (HRQoL) following percutaneous coronary interventions (PCIs). This study thus aimed to assess the impact of PCI on health outcomes among Jordanian patients three months post-procedure. Methods: This prospective descriptive study evaluated health outcomes three months post-PCI among Jordanian patients who had been originally diagnosed with Chronic Coronary Syndrome (CCS) before being scheduled for PCIs. Quantitative data was collected using the updated version of the Coronary Revascularization Outcome Questionnaire (CROQ v2) across a non-probability sample, based on accessibility, of Jordanian patients who had received the procedure at any of several hospitals in Jordan. Multivariate analysis of covariance (MANCOVA) was employed to examine the mean scores of patient-reported outcomes following revascularization, while partial correlations were employed to investigate associations among patients’ age, weight, gender, and the reported results. Results: A total of 101 patients participated in the study, with a predominance of males (n = 85, 84.2%) relative to females (n = 16, 15.8%). The results indicated a statistically significant improvement across all measures assessed across these patients. Furthermore, the results demonstrated that males showed higher physical function, psychological functioning, and cognitive performance relative to females following coronary revascularization surgery. Nevertheless, the results also revealed varied levels of adverse effects following coronary revascularization, with the most commonly reported being discomfort around the groin or arm wound, followed by pain in the same areas. Conversely, the least significant concerns pertained to the emergence of bruises and similar issues in the groin or arm areas where the catheter was inserted. Conclusions: This study shows that PCI improves CAD patients’ quality of life over the initial three-month period post-procedure. Understanding the positive associations of this and the negative consequences that it entails may help healthcare practitioners better identify those patients likely to benefit or suffer from PCI, enabling more appropriate interventions. To understand how PCI affects HRQoL in CAD patients over time, more research based on rigorous study designs and validated metrics is required, however. Full article

Background/Objectives: A large percentage of schoolchildren are children with overweight or obese, and weight gain over time increases the risk of poor health later in life. Motor coordination may be a protective factor, enabling young people to participate in healthy physical activities. However, it is unknown when the relationship between motor coordination and weight first emerges, nor whether it is evident across the body mass index (BMI) spectrum. The aim of this study was to explore what happens with coordination skills [i.e., locomotor coordination (LC), visuomotor coordination (VC), foot object control coordination (FOCC), hand object control coordination (HOCC), global motor coordination (GMC)] applying the 3JS battery, according to age (6 to 11 years) and BMI (normal weight, overweight or obesity) in a sample of 688 Primary Education participants (8.71 ± 1.66 years; 48.8% boys) from Galicia (Spain). Methods: To analyze the differences in the variables of the 3JS battery between age (6–11 years) and BMI (normal weight vs. overweight vs. obesity), they were evaluated using a multivariate analysis of covariance (MANCOVA), introducing the sex category (boy-girl) as a covariate to avoid possible confounding factors. Results: After the application of the 3JS Battery, statistically significant differences were observed depending on age [LC (p < 0.001); VC (p < 0.001); FOCC (p < 0.001); HOCC (p < 0.001); GMC (p < 0.001)] and BMI [LC (p < 0.001); VC (p = 0.008); HOCC (p < 0.001); GMC (p < 0.001)]. No statistically significant differences were found in the interactions between age and BMI (p > 0.05). Conclusions: Locomotor coordination increases progressively with age, both globally and in each of the manifestations, and this is greater the older the schoolchildren are. Schoolchildren with normal weight compared to schoolchildren with overweight or obesity have better global motor coordination, locomotor coordination, global control of objects, and control with the hand.

This study investigates the effects of embodied (breathing exercises) and cognitive interventions on adolescents’ flow experience and cognition patterns. Using a mixed-methods design, 303 vocational high school students were assigned to three groups: Embodied Task Group (N = 108), Cognitive Task Group (N = 100), and Mental Health Course Group (N = 95). Experiment 1 employed a 3×2 Multivariate Analysis of Covariance (MANCOVA) design to compare flow experience dimensions, while Experiment 2 used Epistemic Network Analysis (ENA) to analyze diary entries. Results showed that the Embodied Task Group outperformed the Cognitive Task Group in “Unambiguous Feedback” (η_p² = 0.01, a small effect) and had higher “Transformation of Time” (η_p² = 0.01, a small effect) than the Mental Health Course Group. ENA revealed that the Embodied Group developed stronger body-environment interaction patterns, shifting cognition pattern from psychological evaluations to dynamic bodily processes over time. Conversely, the Cognitive Task Group maintained event-focused cognition with weaker mind–body integration. Findings highlight breathing exercises’ potential to enhance flow experience through embodied awareness and multisensory processing, offering practical implications for mental health education by promoting embodied learning tasks to foster flow experience.

Goal Contents Theory (GCT) postulates that the goals people pursue not only direct their perceptions of and behaviors relevant to goal pursuit, but also hold implications for their well- and ill-being. Extending past sport work grounded in this theory, this study explored athletes’ self-generated goals and examined whether these goals were differentially aligned with goal-related processes and well- and ill-being. A total of 414 university team athletes (206 women and 208 men) completed a questionnaire at the beginning of the sport season. The results showed that intrinsic goals, assessed in an open-ended format, were more heterogeneous in terms of content, and more common among athletes than extrinsic goals. In addition, women reported more intrinsic goals and fewer extrinsic goals than men. MANCOVA revealed that athletes who pursued extrinsic goals reported significantly lower self-efficacy and greater perceptions of goal difficulty than athletes with intrinsic goals. No differences in goal motives and well- and ill-being indicators emerged. Finally, two models were tested that illustrate how goal content is related to self-efficacy for goal attainment, goal motives, and well- and ill-being. Overall, the findings were largely congruent with GCT and indicate that the quality of athletes’ goal-related processes and their well- and ill-being vary as a function of whether they are pursuing intrinsic or extrinsic goals.

Background/Objectives: This study examined the relationship between grit—a measure of perseverance and diligence—and depressive symptoms in the context of the COVID-19 pandemic. While low levels of grit have typically been associated with increased vulnerability to mental health challenges, the pandemic introduced elements that may have altered this relationship. Methods: Using data from 5039 participants in the National Longitudinal Survey of Youth 97, one-way MANCOVAs were conducted to compare depressive symptoms across low-, moderate-, and high-grit individuals before and during the pandemic. Results: The findings show that in pre-pandemic periods, low-grit individuals displayed a significantly higher risk of depressive symptoms than their moderate- and high-grit counterparts. However, during the pandemic, this differential risk diminished, with higher-grit groups showing depressive symptoms comparable to those of lower-grit groups. Conclusions: These results suggest that public health crises entailing limited public mobility and social distancing may alter the traditional protective role of grit, prompting further investigation into how resilience factors interact with external stressors during times of widespread adversity.

Background/Objectives: This paper deals with quality of life (QoL), mental well-being (WB), anxiousness, and stress vulnerability in women with tetany syndrome (TS) in comparison with the population without the syndrome. The aim is to investigate the individual or combined effects of anxiousness, stress vulnerability, and tetany syndrome diagnosis on quality of life and well-being in women. Methods: The research sample was composed of 144 female (in terms of sex) respondents with a diagnosis of tetany syndrome and 123 females without the syndrome (comparative group). The questionnaire battery was used for data collection (WHOQoL-BREF, Warwick–Edinburgh mental well-being scale, STAI (X-2), and Stress Vulnerability Scale). In processing, comparisons, correlations, and MANCOVA analyses were used. Results: The group with tetany syndrome showed significantly lower levels of quality of life (all domains) and well-being and significantly higher anxiousness compared to the group without the syndrome. In vulnerability to stress, a significant difference between groups was not shown. Multivariate testing showed a small interaction effect of tetany syndrome, anxiousness, and stress vulnerability on well-being and quality of life, while anxiousness still had the largest independent effect. Conclusions: Lifestyle aspects seem to be a possible intervening factor that, in interaction with anxiety, contributes to a worse quality of life and well-being in individuals with tetany syndrome. The results contribute to the perception of psychological intervention, in terms of stress management and support for a healthy lifestyle, as important in addition to mineral supplementation or medication treatment.
