Official Source code for 'Eye Feel You: A DenseNet-driven User State Prediction Approach'
No full textThis is the official source code for the paper titled "Eye Feel You: A DenseNet-driven User State Prediction Approach" by Kamrul Hasan and Oleg V. Komogortsev. The paper is currently under review in the ACM Symposium on Eye Tracking Research & Applications, 2026.Subjective self-reports, collected with eye-tracking data, reveal perceived states like fatigue, effort, and task difficulty. However, these reports are costly to collect and challenging to interpret con- sistently in longitudinal studies. In this work, we focus on determining whether objective gaze dynamics can reliably predict subjective reports across repeated recording rounds in the eye-tracking dataset. We formulate subjective-report prediction as a supervised regression problem and propose a DenseNet-based deep learning regressor that learns predictive representations from gaze velocity signals. We conduct two complementary experiments to clarify our aims. First, the cross-round generalization experiment tests whether models trained on earlier rounds transfer to later rounds, eval- uating the models’ ability to capture longitudinal changes. Second, cross-subject generalization tests models’ robustness by predicting subjective outcomes for new individuals. These experiments aim to reduce reliance on hand-crafted feature designs and clarify which states of subjective experience systematically appear in oculomotor behavior over time
Admiration to Action: How Charisma Orientations Towards Waterbirds Influence Their Conservation
No full textInsufficient investment in wildlife that lacks strong aesthetic or emotional appeal to humans poses a significant obstacle to achieving broader conservation goals. Species that are not considered charismatic are nonetheless vital to ecosystems and deserve attention from conservationists, researchers, and the public. However, effective strategies for bridging the gap between these species and traditionally charismatic ones remain underexplored. Our exploratory study introduced the concept of charisma orientations to examine their influence on pro-bird behaviors, such as following guidelines, reporting disturbances, and participating in community advocacy. We identified six relational and socially negotiated orientations—ecological importance, intrinsic right to exist, protection support, affective meaning, and perceived decline—that together represent key perspectives through which waterbirds are understood. A survey of 615 Texas coastal recreationists revealed that relying solely on positive charisma diminishes the appeal of waterbirds for participants. The species likeability frame was relevant only in the context of reporting disturbances, while a moral policy stance (the belief that waterbirds need protection) was significant in predicting advocacy. Younger males and individuals who felt current regulations were adequate were less likely to engage in waterbird conservation behaviors. Our findings suggest that examining the intersection of contested charismatic species and various charisma orientations can uncover subtle nuances often overlooked due to an overemphasis on positive charisma and emotional resonance, which may only partially apply or not apply at all.BiologyHealth and Human Performanc
Multiple Perspectives on Junior Giants: Volunteer Coaches’, Team Parents’, and Caregivers’ Perceptions of Program Impact and Intentions to Return
No full textThis mixed methods study explored perspectives from volunteer coaches and team parents involved in one sport-based youth development program, Junior Giants. The purpose was to (a) compare multiple perspectives on program impact and (b) investigate processes behind program impact and intentions to return. The sample (N = 11,638) included 1541 volunteer coaches, 861 team parents, and 9236 caregivers who completed an online survey assessing perceptions of players’ character development, antibullying, and league organization. Coaches and team parents also responded quantitatively and qualitatively about attending the initial training, use of practice plans, and intentions to return. Coaches reported significantly higher perceptions of participant change in character development and antibullying compared to caregivers (effect sizes were small), and team parents’ perceptions were not significantly different from coaches or caregivers. Perceptions of program outcomes did not differ by sport type (baseball v. softball), binary gender, age, or years in Junior Giants. For process variables, coaches were significantly more likely to attend the training and use the practice plans than team parents (small effects). Several themes emerged from open-ended questions, including not attending the initial team meeting due to schedule conflicts or signing up late to coach, not using practice plans due to limited time or needing modifications, and not intending to return due to child aging out or time commitment. Results suggest Junior Giants is perceived to have a positive impact and offer advice for supporting volunteers in sport-based youth development programs.Health and Human Performanc
Comparison of Repeat Power Ability During a High-Volume Squat Exercise in Resistance-Trained Males and Females
No full textBackground/Objectives: The effect of a high-volume, lower-body resistance exercise session on repeat power ability (RPA), defined as the ability to reach peak power (PP) or near PP during a high-volume resistance training session, remains unclear. The purpose of this study was to analyze the effects of recovery time and sex on loss of power within and across sets during a high-volume, low-load squat session. Methods: Twenty-five resistance-trained males and females (age = 25.5 ± 7.2 years; ht = 169.8 ± 8.9 cm; wt = 75.9 ± 16.9 kg) completed the study. Mean power output across five sets was measured during two sessions (one-minute rest vs. two-minute rest) using a linear position transducer in random order. Five sets at 45% of the participant’s 1RM were completed until power output decreased below 80% of the participant’s within-set PP for two consecutive repetitions or until volitional exhaustion occurred. The data were analyzed with a three-way ANOVA (recovery time by set by sex). Results: The males demonstrated a significant loss across sets for both the one-minute (194 watts) and two-minute recovery period (104 watts), while no change occurred for females in either condition. The males produced greater mean power across both recovery times and sets (p = 0.017). Further, a significant recovery time-by-set interaction was observed (p = 0.015). Mean power decreased an average of 111.3 watts during the one-minute recovery period compared to a loss of 54.0 watts during the two-minute recovery period. Lastly, within-set fatigue occurred during repetitions 9–11 and 11–14 during the one- and two-minute recovery periods, respectively. Conclusions: The data indicate that greater RPA occurs within and across sets with two minutes of rest. In addition, sex must also be considered when implementing a high-volume resistance training session with the goal of training repeat power ability.Health and Human Performanc
Dietary Diversity, Dietary Patterns, and Cardiometabolic Health in University Students: A Cross-Sectional Study
No full textBackground: Cardiometabolic risk is increasingly observed in young adults, particularly during university years, and is not limited to individuals with elevated body mass index. Emerging evidence highlights the presence of normal weight obesity—characterized by excess adiposity and unfavorable body composition despite normal BMI—which may confer early metabolic vulnerability. Dietary diversity is often promoted as a marker of dietary adequacy; however, its relationship with adiposity, body composition, and muscular health remains inconsistent, particularly in Latin American populations. Moreover, few studies have directly contrasted dietary diversity indicators with empirically derived dietary patterns in relation to cardiometabolic and functional outcomes. Objective: To examine the associations between dietary diversity, dietary patterns, and indicators of adiposity, muscular strength, and relative muscle mass in Ecuadorian university students. Methods: A cross-sectional study was conducted among 349 undergraduate students aged 18–26 years enrolled in health sciences programs in Ecuador. Dietary intake was assessed using a validated food frequency questionnaire. Dietary diversity was quantified using the Food and Agriculture Organization’s Individual Dietary Diversity Score, while dietary patterns were identified through principal component analysis followed by k-means clustering. Outcomes included excess body weight, relative muscle mass assessed by bioelectrical impedance analysis, and handgrip strength. Multivariable Poisson and linear regression models were fitted, adjusting for age, sex, academic program, physical activity level, and pre-existing conditions. Results: Despite their young age and low prevalence of diagnosed disease, approximately one-third of the participants exhibited markers of early cardiometabolic risk, including excess body weight and central adiposity. Higher dietary diversity was independently associated with a higher prevalence of excess body weight (adjusted prevalence ratio per one-unit increase in IDDS: 1.17; 95% CI: 1.06–1.30) and with greater relative muscle mass (adjusted β = 0.13; 95% CI: 0.05–0.22), whereas no association was observed with handgrip strength. In contrast, dietary patterns derived from multivariate analysis showed no significant associations with adiposity, muscular strength, or relative muscle mass after adjustment. Conclusions: In this young adult population, dietary diversity captured aspects of overall dietary exposure associated with both increased adiposity and greater lean mass, but not with muscular strength. Empirically derived dietary patterns demonstrated limited discriminatory capacity, likely reflecting dietary homogeneity within the cohort. These findings indicate that dietary diversity alone does not necessarily reflect diet quality and underscore the importance of interpreting diversity metrics alongside indicators of food quality, energy density, and body composition when evaluating early cardiometabolic risk in contemporary food environments.Division of Researc
The stranger you know: Predicting victim-offender relationships in sexual homicides by comparing offender behaviors by crime location
No full textPurpose
Although crime location is known to matter in sexual homicides, it remains unclear whether predictors of the victim–offender relationship differ between indoor and outdoor settings. This exploratory study aims to examine whether these predictors distinguishing stranger and offenders known to the victim vary across crime scene locations.
Design/methodology/approach
The sample included 440 solved adult sexual homicides (victim ages 16–65) from France and Canada. Chi-squared tests assessed the relationships between variables and the victim–offender relationship (stranger = 1, known = 0) across three groups: all cases (n = 440), indoor cases (n = 289) and outdoor cases (n = 151). Statistically significant predictors with sufficient case counts were then entered into logistic regression models for further analysis.
Findings
Strangers were more likely to bring a weapon, have the victim perform fellatio, and remove items from the scene. Offenders known to the victim were more likely to target specific victims and engage in overkill. When analyses were stratified by crime scene location, the indoor model results were similar to the overall findings; however, when the offender moved the victim’s body post crime, the offender was more likely to be someone known to the victim. However, fewer behaviors significantly distinguished stranger and known offenders in outdoor sexual homicides.
Originality/value
To the best of the authors’ knowledge, this study is the first to examine behaviors predicting the victim–offender relationship separately for indoor and outdoor crime scenes, highlighting the importance of context when interpreting offender behavior
Market Price Determination for Ready-to-Cook Catfish Products: Insights from Experimental Auctions
No full textDetermination of the right price is vital for the success of newly developed food products. This study examined the market prices and their determinants for five ready-to-cook catfish products: Panko-Breaded Standard Strips (PBSS), Panko-Breaded Standard Fillet (PBSF), Panko-Breaded Delacata Fillet (PBDF), Sriracha-Marinated Delacata Fillet (SMDF), and Sesame-Ginger-Marinated Delacata Fillet (SGMDF). Market prices were derived using Vickrey’s second-price auction, where the second-highest bid represents the market price. We analyzed experimental auction data from 121 consumers using a logit model to estimate the probability of offering the market price based on product sensory attributes, socio-demographic characteristics of the participants, and the level of competition (panel size). Consumers’ willingness-to-pay (WTP) was elicited in two rounds: before tasting (visual evaluation) and after tasting (organoleptic evaluation) the products. Breaded products received higher market prices than marinated products, with PBDF ranked highest. Sensory traits, especially taste, along with income, education, and grocery shopping involvement, significantly influenced the formation of market price. Increased competition elevated the market prices. Both product features and consumer characteristics significantly affect market price outcomes, and experimental auctions provide a robust tool for understanding consumer behavior toward newly developed food products.Agricultural Science
Principals’ Efforts to Create and Foster an Inclusive School Culture: Pragmatic Approaches in Fast-Growth School Environments
No full textSchool leaders are central to addressing educational inequality by fostering inclusion and belonging within their school communities. In fast-growth educational environments where enrollment surges and demographic shifts outpace resource capacity, school leaders face complex challenges in developing inclusive structures and cultures for students with disabilities. In this qualitative case study, the authors examined how 18 principals across PreK-12 grade levels in three rapidly expanding Texas districts conceptualized and enacted inclusive leadership. Thematic analysis of semi-structured interviews and focus groups revealed that while principals believed all students are capable of learning, they defined inclusion philosophically but implemented pragmatically limited notions of inclusion shaped by their districts’ organizational structures and continuum of services approaches to special education. Findings illustrate that fast-growth contexts amplify tensions between compliance and care, as school leaders balance external accountability and resource constraints with efforts to cultivate school cultures grounded in empathy, relationships, safety, and belonging. The study presents a complicated picture of how principals navigate pragmatic constraints while pursuing inclusive practices for students receiving special education services. Inclusive educational leadership in fast-growth school environments is more likely to occur when leaders reframe inclusion not as placement, but as a shared commitment to recognizing every student’s capability within a responsive community.Counseling, Leadership, Adult Education, and School Psycholog
Respiratory Rehabilitation after COVID-19: Efficacy of Inspiratory Muscle Training on Lung Function, Quality of Life and Sleep Quality: A Randomized Clinical Trial
No full textBackground and Purpose: Post-COVID-19 syndrome significantly impacts respiratory function and quality of life. Inspiratory muscle training (IMT) has been proposed as a potential intervention to improve respiratory muscle strength and overall recovery. This study aimed to evaluate the effects of IMT on respiratory muscle performance, lung function, functional capacity, sleep quality, and quality of life in individuals with post-COVID-19 syndrome. Methods: Nineteen individuals with post-COVID-19 syndrome were randomized into an IMT group (N = 10) or a sham group (N = 9). The IMT group performed eight weeks of training at 50% of maximal inspiratory pressure (MIP), while the sham group used a non-load device. Outcomes included MIP (cm H2O), functional capacity (6MWT), lung function (spirometry), sleep quality (PSQI), and quality of life (SF-36). Results: The IMT group showed significant improvements in MIP (125.50 ± 22.50 vs. 93.67 ± 20.87 cm H2O; p = 0.036; Cohen’s d = 0.50), PSQI (4.40 ± 2.50 vs. 9.00 ± 2.80; p = 0.011; Cohen’s d = 0.60), and SF-36 (p = 0.030). The IMT group also increased 6MWT distance by 58.36 ± 25.10 m. Conclusions: IMT significantly improved respiratory muscle strength, sleep quality, and quality of life in post-COVID-19 syndrome. These findings suggest that IMT may be an effective intervention, warranting further studies to confirm long-term benefits.Respiratory Car
