An eco‐driving approach for ride comfort improvement

Nov 01, 2021IET Intelligent Transport Systems

Addressing the dual challenge of motion sickness in autonomous vehicle passengers and transportation-related carbon emissions, this paper proposes a synergistic optimization framework integrating eco-driving strategies with personalized comfort modeling. Innovatively, it introduces self-organizing maps (SOM) for the first time to jointly characterize the coupled effects of driving style on ride comfort and energy consumption. Leveraging real-world driving behavior data, it extracts multidimensional driving features to construct an interpretable comfort–eco-efficiency joint evaluation model and generates natural-language, personalized improvement recommendations. Experiments demonstrate a 57.7% improvement in mainstream comfort metrics and up to 47.1% reduction in greenhouse gas emissions—significantly outperforming baseline methods. Key contributions include: (1) an SOM-driven paradigm for modeling the coupling between ride comfort and environmental impact; (2) a data-driven framework for generating personalized, human-interpretable recommendations; and (3) a dual-objective co-optimization mechanism tailored for human–autonomous vehicle collaboration.

Twitter and disability activism: leadership and relevant topics in the online conversation

Aug 12, 2026

This study examines the ecology of digital disability activism on Twitter within Latin American contexts. Drawing on a dataset of over 18,000 tweets tagged with #disability, the authors construct a mention network and employ social network analysis, graph-theoretic modeling, and visualization via Gephi using the Force Atlas 2 algorithm. Findings reveal a highly fragmented online discourse in which women activists occupy central positions and collaborate closely with institutional actors such as the ONCE Foundation, forming critical support hubs that have garnered political and institutional attention. The research elucidates gendered advocacy patterns and organizational synergies, thereby advancing understanding of disability-related digital activism in the Global South.

Technology, education and critical media literacy: potential, challenges, and opportunities

Aug 11, 2026

This study addresses the limitations of current media literacy education in effectively integrating technology and fostering critical capacities amid challenges such as disinformation and deepfakes. Drawing on survey data from 141 university students and semi-structured interviews with experts, the research employs mixed-methods analysis to examine the role of technology in media education. Findings indicate that while digital tools hold significant potential to enhance critical thinking and ethical reflection, their integration into curricula remains limited and is hindered by insufficient teacher training. The paper proposes a new media literacy framework centered on ethical reflection and critical engagement, advocating a shift beyond instrumental technology use toward practices that emphasize questioning, evaluating media content, and promoting civic participation—thereby offering both theoretical insights and practical pathways for media education in the digital age.

Shaping the notion of #wellbeing in the therapy culture context: an analysis through Instagram narratives

Aug 11, 2026

This study investigates the discursive construction of wellbeing on Instagram through the #wellbeing hashtag, revealing its gendered characteristics and dominant narrative tendencies. Employing a multimodal analytical framework that integrates text mining, hierarchical clustering, non-parametric statistical tests, computer vision–based image classification, and object detection, the research examines 9,844 posts. For the first time, it combines textual semantics, visual themes, and gender representation to demonstrate that the #wellbeing discourse is highly feminized, predominantly centered on mental health and spiritual growth. Content related to healing and positive psychology generates the most user engagement, whereas fitness and nutrition remain comparatively marginalized. The analysis further identifies two core narrative frameworks structuring this online wellbeing discourse.

Mediatised Participation: Citizen Journalism and the Decline in User-Generated Content in Online News Media

Aug 11, 2026

This study investigates the decline of citizen journalism and user-generated content (UGC) in online news media and the transformation of participatory mechanisms. Through a systematic literature review, it critically examines audience participation behaviors, journalists’ efforts to uphold professional boundaries, and media organizations’ commercial strategies, uncovering the underlying causes of UGC’s waning viability. The research introduces the concept of “mediatized participation” to reconceptualize the nature of audience engagement in the digital era and argues that citizen journalism, as an institutional innovation, may have largely failed. Key findings indicate that widespread audience reluctance to produce content, journalists’ reinforcement of professional authority, and media prioritization of profitability collectively undermine the sustainability of UGC models.

IMFACT: Counterfactual Explanations for Time Series via Intrinsic Mode Function Substitution

Aug 05, 2026

This work addresses the challenge that counterfactual perturbations applied directly in the original feature space of oscillatory time series often disrupt their temporal structure, yielding physically implausible explanations. To overcome this, the authors propose a model-agnostic counterfactual generation framework that first decomposes the input signal into intrinsic mode functions (IMFs) via empirical mode decomposition (EMD), then selects critical IMFs based on variance. A three-nearest unlike neighbor (NUN) iterative replacement strategy is employed to modify these key IMFs, guiding the classifier toward the target class while preserving the signal’s physical plausibility. This approach represents the first method to construct counterfactual explanations in the IMF space. Experiments on the FaultDetectionA and FruitFlies datasets demonstrate consistent improvements over existing baselines across reliability, plausibility, and proximity metrics.
