Karate training relies on subjective manual evaluation of intricate motions, hindering scalable, consistent coaching. This paper proposes MMAF-Net, a multimodal AI framework for real-time karate action recognition and automated performance feedback. Its three-branch deep learning architecture integrates visual, pose-estimation and inertial sensor streams to extract complementary motion features, fused via a temporal attention module to classify 23 karate action types accurately. Trained and validated on MS-KARD (2.8 million video frames and 5.6 million sensor readings from dual cameras and three IMUs), the model generates explainable coaching tips through rule-based modules referencing prediction confidence, posture bias and motion stability. Tests yield 96.3% accuracy and 95.1% F1-score, outperforming benchmarks like KarateNet. With only 24 ms inference latency, this real-time system suits interactive martial arts training scenarios.

Digital/hybrid work makes e-collaboration skills key graduate employability indicators, yet current assessment methods (self-reports, crude skill lists) are ineffective for tech-mediated work. This paper proposes a taxonomy-based approach to quantify such skills from digital traces and analyze their employment correlations. Using the Kaggle Employment Skills dataset, a formal e-collaboration taxonomy (platforms, coordination, artifact collaboration, documentation, workflow integration) was developed. Text processing and rule-based mapping generated skill indicators and an E-Collaboration Skill Index, with predictive models tested for discrimination/calibration. Workflow integration, coordination, and documentation emerged as key signals; the index and its models outperformed baselines. Organized digital footprints effectively measure e-collaboration skills, which correlate significantly with employment outcomes, informing curriculum design, career services, and hiring analytics.
Resource allocation for cultural and creative digital platforms is complex because project evaluation relies on uncertain, multidimensional, and subjective values that are not determined solely by financial performance. This paper proposes a framework, the Fuzzy Creative-Platform Resource Allocation (Fuzzy-CCRA), to prioritize creative projects under uncertainty and make the process transparent and explainable. The framework combines Kickstarter data (648,400 projects) with Behance engagement data to enrich cross-platform analysis. Nine decision criteria were defined and represented using a five-level fuzzy linguistic scale with triangular membership functions. The main approaches to ranking were Fuzzy TOPSIS and Fuzzy VIKOR, and sensitivity analysis was used to assess robustness. The framework produced consistent allocation levels, with Spearman rank correlations above 0.876 in eight scenarios and a Precision@50 of 0.824. Fuzzy-CCRA proposes a powerful, interpretive, and data-driven system of fair distribution of resources on creative platforms.

The widespread adoption of online and blended learning has reshaped higher education, yet student engagement frequently diminishes over time, and traditional gamification suffers from the unsustainable novelty effect. This study constructs a Multidimensional Dynamic Incentive Model (MDIM) by synthesizing behavioral incentive theory and self-determination theory, featuring progressive task difficulty, real-time data feedback, and contextualized narrative support. A 32-week longitudinal quasi-experiment was carried out with two parallel classes, using mixed-effects and cross-lagged models for data analysis. Results indicate that DDIM significantly alleviates mid-term engagement decline, sustains long-term learning participation, and stably enhances academic performance without exacerbating the Matthew effect. This research provides an adaptive, sustainable gamification design for e-collaboration systems and technology-enhanced course development, offering empirical and practical implications for digital learning governance in higher education.
With the rapid development of China's society and economy, small and medium-sized enterprises (SMEs) hold a significant position among Chinese enterprises. The financial management capacity evaluation in SMEs constitutes a quintessential multi-attribute decision-making (MADM) challenge. In recent studies, scholars have increasingly combined methods such as the Logarithmic TODIM (LogTODIM) method and entropy weight to tackle complicated evaluation tasks, while Z-numbers are widely adopted to effectively describe uncertain information with varying degrees of credibility. This paper establishes a Z-number-based LogTODIM (ZN-LogTODIM) model, which is specially designed to handle MADM problems under Z-number environments. To verify the feasibility and efficiency of the proposed approach, a concrete numerical example concerning SMEs' financial management capacity evaluation is conducted. The results show that this method performs well and can be further applied to practical decision-making scenarios in operational and educational management.

Under the "dual-carbon" goal, hidden emissions in urban construction archives management demand urgent attention. Evidence from Nanjing's 2023 digitalization project reveals a 25% emission rise during transition due to procuring 200+ scanners and 5 servers, highlighting a carbon efficiency gap. Using measured data and scenario simulation, this study uncovers a two-stage "transition-stable" carbon mechanism, establishes a life-cycle accounting framework (formation, storage, inspection, destruction), and proposes a technology-management-policy reduction strategy. Emissions are projected to drop 76.4% by 2025, shifting from paper/transport to electronic storage. Management optimization drives over 50% of savings; a cross-department digital platform alone cuts 3.3 tons CO2e at & YEN;320/ton. Higher standardization enables the Planning Bureau to cut emissions by 65.4%, versus 46.4% for the Urban Management Bureau reliant on on-site access. The study offers practical tools to balance digital transition and carbon control, aiding governance of hidden urban emissions.

The aim of this study was to investigate the status of collaboration between librarians and academics in the Department of Library and Information Science (LIS). The study employed qualitative research method and the purposive sampling to select the research participants who were librarians and LIS academics. The data was gathered from librarians and LIS academics through the structured interviews. The findings revealed that the level of collaboration between LIS academics and librarians is satisfactory; however, it is too minimal to influence the entire LIS profession as they work in isolation which makes them lack commitment, dedication, and respect towards one another. The study recommends that librarians and LIS academics’ collaboration must be sensitised by enhancing collaboration engagement activities, initiating collaboration engagement groups, and building and maintaining relationships. It is also recommended the strategies for producing well-qualified graduates who meet the LIS job market's expectations be developed while keeping up with current trends in the LIS field.
