摘要： Blended learning is the latest and inevitable trend in the development of education. Although blended learning research is on the rise, fewer studies examine the learning behaviour of college students in blended learning environments. This study aimed to investigate the learning behaviours of students in the field of computer science and examine these behaviours using data mining algorithms, taking the teaching practice of the Digital Signal Processing course as a case study. A total of 18 behavioural indicators were extracted and divided into three categories: basic learning behaviours, self-regulated learning behaviours, and extended learning behaviours. Data analysis of the behavioural indicators yielded the following conclusions: (1) Students did not have the habit of watching course playback and were less receptive to multiple online learning platforms;(2) Students' midterm performance and duration of livestream watching directly affected their basic learning behaviours, with all indicators of self-regulated and extended learning behaviours showing significant correlations;(3) The clustering of learning behaviours yielded four different learner patterns, which calls for personalised teaching strategies;(4) The random forest algorithm had an accuracy of 95.4% in predicting performance of the four types of learners.

摘要： Rainey Bethea’s execution in Kentucky in 1936 was the last legal public hanging in the US. Although some aspects of Bethea’s death were typical of hangings of Black men in the Jim Crow South, this execution became a spectacle. It drew crowds of up to 20,000 people and national media attention, largely because a white woman was charged with hanging Bethea. The county sheriff, Florence Thompson, breached women’s traditional roles under Jim Crow as executioner rather than victim. As a result, it sparked a national controversy about power, resistance, and the gendered nature of capital punishment; two years later, Kentucky became the last state to outlaw public *** research positions the spectacle of Bethea’s execution in the broader political and social context of the 1920s and 30s to examine the state’s efforts to centralize power alongside the activism of African Americans who chipped away at Jim Crow. My work tracks the confluence of three forces prompting a significant change in capital punishment: the impact of women disrupting gender hierarchies, the increasing political power of Black Kentuckians in a border state, and politicians and other authorities attempting to shirk claims of lawlessness and backwardness. Together these elements reveal that, rather than a concession to national shaming of Kentucky, the banning of public hangings signaled the state’s grab for power during a moment of social fracture in the New Deal era. By examining the transition from public to private executions in a broader social and political context, my work challenges notions of “modernizing” the penal system and provides key context for contemporary debates about capital punishment.

摘要： This research aims to explore the comprehension of historical Korean archives authored by common literati. Numerous endeavors have been made to study Korean historical documents;however, the majority of these endeavors focus solely on royal documents. By comparing the distinct linguistic characteristics between royal and commoner languages, this study challenges the applicability of the royal language-centric approach to commoner documents. In particular, we investigate the feasibility and limitations of existing resources that share the same writing system (Hanja) as historical Korean documents for processing Korean common literati documents. Through our investigation, we propose a simple yet effective methodology that enables the utilization of Hanja-based language resources in processing Korean common literati documents: the removal of special characters. We demonstrate that aligning characteristics of Hanja-based resources allows considerable performance improvements. To the best of our knowledge, our study represents the first research endeavor to concentrate on the comprehension of common literati documents.

摘要： In long-lived mammals, females must pay the costs of gestation and lactation without jeopardizing future survival and reproduction. Insufficient energy and protein intake during summer can have severe consequences for nutritional condition and body mass, which directly impact survival and reproduction. Because behavior is one of the primary mechanisms by which animals cope with constraints on survival and reproduction, individual herbivores should attempt to maximize nutrient intake by consistently selecting the best foraging habitats available to them. Yet, herbivores’ ability to optimize their foraging behavior is constrained by a variety of intrinsic (e.g., memory) and extrinsic (e.g., predation risk) factors. One result of such constraints is that foraging strategies often vary considerably among individuals in a population. The causes and consequences of individual variation have long been the subject of investigation but are often overlooked in wildlife ecology and management. Although previous work has clearly established links between nutrition and individual performance, the mechanisms underpinning relationships among individual behavior, nutrition, and population performance remain elusive. We quantified relationships among the foodscape (i.e., spatiotemporal variation in forage biomass and quality), behavior, and performance (i.e., survival and reproduction) in three populations of bighorn sheep (Ovis canadensis) that spanned a range of environmental conditions, in mid-elevation grasslands and mountainous alpine systems. We first investigated the nutritional underpinnings of variation in life-history strategies exhibited by bighorn sheep. Bighorn sheep are typically considered to be capital breeders that rely on stored energy reserves to finance reproduction. This generality is supported by the observation that in many northern bighorn populations, survival of neonates is insensitive to temporal changes in spring green-up, and capital reserves strongly in

摘要： Cognitive load (CL), defined as the mental effort required to process information, plays a pivotal role in user performance and experience in various domains, particularly within computer science (CS) and information systems (IS). As technology grows increasingly interactive, understanding and measuring CL is crucial for designing adaptive, user-centered systems. This study investigates trends in CL measurement techniques in CS and IS research from 2017 to 2024, focusing on emerging tools, methods, and their applications. A systematic literature review (SLR) was conducted to provide a comprehensive overview of CL's role in CS and IS, the methods used to detect it, and how it is analyzed across different tasks and environments. The motivation behind this research stems from the growing need to optimize user experiences and system efficiency through better CL management. The findings highlight a shift toward multimodal CL measurement, integrating subjective, behavioral, performance-based, and physiological data, often analyzed with machine learning in domains like human-computer interaction, education, and immersive technologies. This research highlights the importance of accurate CL measurement and suggests future directions for enhancing adaptive system design through the integration of CL metrics. Building upon these findings, future research should focus on advancing CL measurement through survey item sequencing, multimodal data integration, and device-task comparisons, while also exploring the use of AI for robust CL detection. Future research should explore survey design, multimodal data integration, device-task comparisons, and AI-based CL detection. Building on these insights, this study proposes developing non-intrusive, adaptive e-learning interfaces to optimize user engagement and personalization within LMS environments.

摘要： Computer science (CS) education has experienced rapid growth over the past decade with student demand leading to new courses or course pathways being offered in K-12 educational settings. Student demand has been matched by parent/community and technology industry support. Educators have quickly responded to the demand by expanding course offerings, yet rapid change comes with growing pains. This research study is an exploration of educator perceptions and experiences implementing CS education. Two hundred four survey responses were obtained from diverse public and private school K-12 educators representing 36 of 50 U.S. states and the District of Columbia. The overarching goals of this study are to represent CS educator responses related to their current experiences specific to the following contexts: (a) external and internal challenges implementing CS education, (b) areas of interest for professional learning of CS content and instructional strategies including strategies that promote equitable instruction, and (c) CS teacher community engagement including access to CS-focused professional development (PD). Understanding teacher perceptions about CS implementation can benefit the CS community of research by identifying areas of challenge, improving PD offerings, specifying PD content, and exposing new areas for support needed by both novice and experienced CS teachers. This study can provide fresh perspectives which can lead to solutions for providing enhanced support for the growing workforce of K-12 novice and experienced CS educators.

摘要： Semi-supervised Action Quality Assessment (AQA) using limited labeled and massive unlabeled samples to achieve high-quality assessment is an attractive but challenging task. The main challenge relies on how to exploit solid and consistent representations of action sequences for building a bridge between labeled and unlabeled samples in the semi-supervised AQA. To address the issue, we propose a Self-supervised sub-Action Parsing Network (SAP-Net) that employs a teacher-student network structure to learn consistent semantic representations between labeled and unlabeled samples for semi-supervised AQA. We perform actor-centric region detection and generate high-quality pseudo-labels in the teacher branch and assists the student branch in learning discriminative action features. We further design a self-supervised sub-action parsing solution to locate and parse fine-grained sub-action sequences. Then, we present the group contrastive learning with pseudo-labels to capture consistent motion-oriented action features in the two branches. We evaluate our proposed SAP-Net on four public datasets: the MTL-AQA, FineDiving, Rhythmic Gymnastics, and FineFS datasets. The experiment results show that our approach outperforms state-of-the-art semi-supervised methods by a significant margin.
