Near-lossless coding schemes traditionally rely on uniform quantization to control the maximum absolute error ($L_{\infty }$ norm) of residual signals, often assuming a parametric model for the source distribution. This paper introduces a novel design framework for non-uniform, entropy-aware $L_{\infty }$-oriented scalar quantizers that leverages a tight and differentiable approximation of the $L_{\infty }$ distortion metric and does not require any parametric density function formulations. The framework is evaluated on both synthetic parametric sources and real-world medical depth map video datasets. For smoothly decaying distributions, such as the continuous Laplacian or discrete two-sided geometric distributions, the proposed method naturally converges to near-uniform quantizers, consistent with theoretical expectations. In contrast, for sparse or irregular sources, the algorithm produces highly non-uniform bin allocations that adapt to the local distribution structure and improve rate-distortion efficiency. When embedded in a residual-based near-lossless compression scheme, the resulting codec consistently outperforms versions equipped with uniform or piecewise-uniform quantizers, as well as state-of-the-art near-lossless schemes such as JPEG-LS and CALIC.

The rapid rise of bio-hybrid robots and hybrid human–AI systems has triggered an explosion of terminology that inhibits clarity and progress. To investigate how terms are defined, we conduct a narrative scoping review and concept analysis. We extract 60 verbatim definitions spanning engineering, human–computer interaction, human factors, biomimetics, philosophy, and policy. Entries are coded on three axes: agency locus (human, shared, machine), integration depth (loose, moderate, high), and normative valence (negative, neutral, positive), and then clustered. Four categories emerged from the analysis: (i) machine-led, low-integration architectures such as neuro-symbolic or “Hybrid-AI” models; (ii) shared, moderately integrated systems like mixed-initiative cobots; (iii) human-led, medium-coupling decision aids; and (iv) human-centric, low-integration frameworks that focus on user agency. Most definitions adopt a generally positive valence, suggesting a gap with risk-heavy popular narratives. We show that, for researchers investigating where living meets machine, terminological precision is more than semantics and it can shape design, accountability, and public trust. This narrative review contributes a comparative taxonomy and a shared lexicon for reporting hybrid systems. Researchers are encouraged to clarify which sense of Hybrid-AI is intended (algorithmic fusion vs. human–AI ensemble), to specify agency locus and integration depth, and to adopt measures consistent with these conceptualizations. Such practices can reduce construct confusion, enhance cross-study comparability, and align design, safety, and regulatory expectations across domains. Full article

Antimicrobial resistance (AMR) constitutes a major global health challenge, driven significantly by inappropriate antibiotic use in human medicine. Despite the existence of evidence-based guidelines, variability in antibiotic prescribing persists, influenced by psychosocial factors, diagnostic uncertainty, patient expectations, and local prescribing cultures. Outpatient care, the setting in which most antibiotics are prescribed, is particularly affected by such challenges. Traditional top-down interventions, such as national guidelines, often fail to achieve sustained behavioral change among prescribers. In this comprehensive review, we provide an overview of the psychological and behavioral factors influencing antimicrobial stewardship (AMS) implementation, as well as describe a bottom-up project working to meet these challenges: the “Antibiotic Therapy in Bielefeld” (AnTiB) initiative. AnTiB employs a cross-sectoral strategy aimed at developing rational prescribing culture by means of locally developed consensus guidelines, interdisciplinary collaboration, and regularly held trainings. By addressing both the organizational and psychological aspects of prescribing practices, AnTiB has facilitated a harmonization of antibiotic use across specialties and care interfaces at the local level. The initiative’s success has led to its expansion within Germany, including through the creation of the AMS-Network Westphalia Lippe and the development of AnTiB-based national pediatric recommendations. These projects are all grounded in social structures designed to strengthen the long-term establishment of AMS measures. Our efforts underscore the importance of considering local social norms, professional network, and real-world practice conditions in AMS interventions. Integrating behavioral and social science approaches into outpatient antimicrobial stewardship—exemplified by the practitioner-led AnTiB model—improves acceptability and alignment with stewardship principles; wider adoption will require local adaptation, routine outpatient resistance surveillance, structured evaluation, and sustainable support.

Background: Multiple sclerosis (MS) is a chronic auto-immune neuroinflammatory disorder presenting as a range of systemic and neurological symptoms, including cognitive impairment. Emerging evidence suggests that diets targeting brain health—such as the Mediterranean (MED) and Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diets—may improve cognitive function; however, studies examining their role in people living with MS are limited. Methods: We examined cross-sectional associations between diet and cognition data from 967 participants in the United Kingdom Multiple Sclerosis Register (UKMSR). Dietary pattern scores (alternate Mediterranean; aMED, and MIND) were derived from the 130-item EPIC-Norfolk food frequency questionnaire. Cognition was assessed using the MS-specific Cognitron-MS (C-MS) battery (13 tasks) and summarised as overall cognition (global G factor) and four domains (object memory, problem solving, information processing speed [IPS], and words memory). Cognitive outcomes were expressed as Deviation-from-Expected (DfE) scores standardised to demographic and device characteristics using external regression-based norms. Linear models were adjusted for total energy intake, MS phenotype, disease duration since diagnosis, and current disease-modifying therapy (DMT) use. Interactions tested moderation by MS phenotype (relapsing vs. progressive MS) and current DMT use (yes vs. no). Sensitivity analyses included within-domain multiple-comparison control, rank-based inverse-normal transformation, and winsorisation. Results: Greater alignment with aMED and MIND dietary patterns were associated with higher scores in specific cognitive domains but not in overall cognition. Higher aMED scores were associated most consistently with better IPS, while higher MIND scores were additionally associated with better words memory. In categorical models, participants with the middle or highest tertiles of aMED or MIND scores performed up to ~0.4 SD better on tasks of Verbal Analogies, Word Definitions, Simple Reaction Time, Words Memory Immediate, or Words Memory Delays compared with those in the lowest tertile. These findings were robust across sensitivity analyses. Stratified analyses showed differential cognitive performance and diet-cognition associations by MS phenotype and DMT use. Conclusions: Mediterranean and MIND dietary patterns showed modest cross-sectional associations with specific cognition domains, with differential cognitive performance in different subgroups according to MS phenotype and DMT use. Although causal inference is not possible, our findings indicate future MS-related dietary studies (longitudinal and/or randomised controlled trials) examining cognitive function domains across different MS subgroups are warranted.

Motherhood regret still constitutes a major taboo that limits the possibility of processing the negative exposure to being a mother. This qualitative study involved Italian women living both in Italy and abroad, where traditional patriarchal thinking remains influential. Sixteen women defining themselves as ‘regretful were interviewed to explore their experiences of regret, the changes following the birth of children, family and social support, and employment. The thematic analysis highlighted several recurring themes: the idealisation of motherhood and the hidden struggles it conceals; the guilt associated with feeling inadequate and the indifference of some fathers; the social pressure that compels women to conform to maternal expectations; the perception of being trapped in a predefined role; and the conflict between personal identity and the ideal of the “perfect mother.”. The findings reveal that maternal regret is deeply intertwined with internalised patriarchal norms, the myth of the “good mother,” and the social expectation of women’s self-sacrifice. Despite recognising these as cultural constructs, participants expressed feelings of guilt, anger, and inadequacy, intensified by the unequal division of domestic and parental responsibilities. This issue and the need for a revival of women’s consciousness-raising groups to open a space for dialogue on the topic in countries where patriarchy is still strong, such as Italy, are discussed.

As Taiwan’s population ages, traditional filial piety expectations face modernization challenges, yet few studies examine how emergent adults linguistically negotiate these cultural tensions digitally. This study addresses this gap by analyzing how emerging adults in Taiwan express and reinterpret filial obligations toward aging parents through online discourse. Emerging adults represent a particularly meaningful demographic because they straddle traditional filial norms and modern independence, making their language use a valuable indicator of cultural transition. We analyzed 1976 Dcard posts from 30 discussion threads (2017–2023) using computational linguistics. LIWC-22 assessed emotional expression patterns, while Sketch Engine conducted keyness analysis and collocation mapping around filial care keywords. Posts were compared against Chinese web corpus norms. Quantitative emotion analysis revealed dominant positive emotions (M = 3.93) alongside significant negative emotions (M = 3.30), with anger and sadness exceeding broader Chinese online communication norms. Keyness analysis identified economic concerns as central themes. Collocation analysis around “filial piety” showed associations with “limits”, “willingness”, and “define”, indicating conditional rather than absolute conceptualization. Findings indicate that emerging adults in Taiwan reinterpret filial piety through reciprocal emotional bonds rather than strict hierarchical duty, negotiating traditional expectations with contemporary economic realities and personal autonomy. The implications of these findings highlight how cultural values adapt in response to modernization and digital communication, offering insight into evolving intergenerational relationships and informing future cross-cultural aging and caregiving research.

Gray divorce, defined as the dissolution of marriages among individuals aged 50 and above, has become an increasingly significant issue in Türkiye. Official statistics in Türkiye show that between 2001 and 2024, divorces among individuals aged 50 and above increased both in absolute numbers and as a proportion of total divorces, rising nearly threefold during this period. These increases reflect broader demographic and social changes, such as population ageing, longer life expectancy, changing expectations of marriage, and shifting gender norms. Using sociological literature on modernization and family change, as well as official statistical data, this review synthesises existing knowledge and situates gray divorce within global debates on family transformation. Findings from gray divorce studies indicate that women’s increasing autonomy, life cycle transitions such as retirement or empty nest experiences, and greater societal acceptance of divorce contribute to this trend. Furthermore, gray divorces have broad implications for intergenerational relationships, care responsibilities, and social policies. Specifically in Türkiye, regional differences show that divorce among the elderly is more prevalent in western urbanized provinces, where individualism and secular values prevail, and significantly less common in eastern regions, where traditional and religious norms are stronger. The increasing prevalence of this phenomenon highlights the need for more empirical research and policy responses that are appropriate to Türkiye’s demographic, regional, and cultural transformations.

This study investigates the perceptions of halal food among theology students from three culturally diverse cities: Istanbul, Berlin, and Kuala Lumpur. As individuals receiving formal religious education, theology students are expected to exhibit strong awareness of Islamic dietary principles. Utilizing a quantitative research design, data were collected from 210 participants via online surveys using validated Likert-type scales measuring halal awareness, halal literacy, religious commitment, social influence, perceived behavioral control, price value, hedonic motivation, and consumption habits. One-way ANOVA and post hoc Tukey tests revealed significant differences between cities in nearly all variables. Students in Kuala Lumpur consistently demonstrated higher scores, indicating a stronger alignment with institutionalized halal systems and collectivist cultural norms. Berlin participants reported lower awareness and influence levels, likely reflecting a more secular and individualistic environment. Istanbul students fell between the two, showing strong religious motivation but less structural support. The findings highlight how halal food perceptions are shaped not only by individual religiosity but also by cultural, political, and economic contexts. This study contributes to the literature by offering a cross-cultural perspective on halal consumption and underscores the importance of integrating structural and cultural factors into religious food behavior research.

Masculinity norms and gender socialization play a critical role in shaping boys’ attitudes, behaviours, and interactions within society. In South Africa, historical legacies of colonialism and apartheid, coupled with deeply ingrained cultural and societal expectations, have contributed to rigid masculinity norms that emphasize dominance, emotional restraint, and aggression. These constructs not only influence boys’ development but also have significant implications for gender-based violence (GBV). This paper explores how norms of masculinity and processes of gender socialization among boys in South Africa shape attitudes and behaviours that contribute to gender-based violence (GBV). The central aim is to offer a critical theoretical synthesis and contextual analysis that informs the development of gender-equitable policies and interventions. Drawing on theoretical frameworks such as hegemonic masculinities, intersectionality, and social learning theory, this study examines how historical, cultural, and socio-economic factors shape gender socialization and influence boys’ developmental trajectories. Through an intersectional lens, this paper underscores the urgent need to challenge harmful masculinity norms and promote alternative models that encourage emotional expression, empathy, and equitable gender relations. Finally, it provides recommendations on how these harmful norms can be disrupted through educational, community, media, and policy-level reforms to foster healthier masculinity norms and reduce GBV in South Africa.

Continuous technological, ecological, and digital transformations reshape urban mobility systems. While sustainable mobility has become a dominant keyword, there are many different approaches and policies to help achieve lasting and properly functioning change. This study applies a comprehensive qualitative policy analysis to influential and leading sustainable mobility approaches (i.a. Mobility Justice, Avoid–Shift–Improve, spatial models like the 15-Minute City and Superblocks, governance frameworks such as SUMPs, and tools ranging from economic incentives to service architectures like MaaS and others). Each was assessed across structural barriers, psychological resistance, governance constraints, and affective dimensions. The results show that, although these approaches provide clear normative direction, measurable impacts, and scalable applicability, their implementation is often undermined by fragmentation, Policy Layering, limited intermodality, weak Future-Readiness, and insufficient participatory engagement. Particularly, the lack of sequencing and pacing mechanisms leads to policy silos and societal resistance. The analysis highlights that the main challenge is not the absence of solutions but the absence of a unifying paradigm. To address this gap, the paper introduces CalmMobility, a conceptual framework that integrates existing strengths while emphasizing comprehensiveness, pacing–sequencing–inclusion, and Future-Readiness. CalmMobility offers adaptive and co-created pathways for mobility transitions, grounded in education, open innovation, and a calm, deliberate approach. Rather than being driven by hasty or disruptive change, it seeks to align technological and spatial innovations with societal expectations, building trust, legitimacy, and long-term resilience of sustainable mobility.

Mortality studies comparing married men to never-married or formerly married men have consistently found that married men have a noticeable mortality advantage. This paper takes a novel perspective—examining mortality outcomes from the perspective of married men only and comparing those who coreside with any parents, in-laws, or their spouse only. The analyses use CenSoc data set, consisting of the 1940 Full Count United States Census linked to the Social Security Administration Death Master Files and includes 1.7 million married men between the ages of 21 and 45 years old residing with their spouse, and who died between 1975 and 2005. The results show that married men who live with only a spouse but no parental generations have an older age at death, and being a household head has an additional advantage. Living with either or both of their parents is associated with a reduction in life of 4 months, or 2 months for those who live with their in-laws. The conclusion reached is that longevity is associated with the possible burden of living with one’s parents, coupled with the reasons that may have led to the particular living arrangement. The effect of coresidence is, in turn, filtered through expectations about intergenerational relationships and norms regarding coresidence. The coresidence experience can become part of a trajectory, leading to declines in longevity. Full article

Humans in a society generally tend to implicitly adhere to the shared social norms established within that culture. Robots operating in a dynamic environment shared with humans are also expected to behave socially to improve their interaction and enhance their likability among humans. Especially when moving into close proximity of their human partners, robots should convey perceived safety and intelligence. In this work, we model human proxemics as robot navigation costs, allowing the robot to exhibit avoidance behavior around humans or to initiate interactions when engagement is required. The proxemic model enhances robot navigation by incorporating human-aware behaviors, treating humans not as mere obstacles but as social agents with personal space preferences. The model of interaction positions estimates suitable locations relative to the target person for the robot to approach when an engagement occurs. Our evaluation on human–robot interaction data and simulation experiments demonstrates the effectiveness of the proposed models in guiding the robot’s avoidance and approaching behaviors toward humans.

Prescriptive grammars of Netherlandic Dutch usually explicitly warn against mixing T- and V-pronouns. Although the prescriptive norm opposes mixing, pronoun mixing does occur, and its use can often be interpreted as strategic, in the sense that mixing pronouns might help to balance conflicting needs such as signaling respect and formality to the addressee on the one hand as well as expressing closeness on the other hand. This article explores the perception of pronoun mixing among high school students who were in the process of acquiring the norm. As part of a student science project, we asked students to categorize real-world examples of pronoun mixing that they themselves had gathered as a strategy or as a mistake. Based on the students’ responses, we extrapolated that the most acceptable forms of mixing were brief switches to V in a T-context to express humor or urgency and—if there was no clear default pronoun—that mixing was most acceptable (1) when the text was free of spelling errors and other signs of sloppiness, (2) when the mixing was intersentential, (3) when the number of switches was infrequent, and (4) when there was a clear division of tasks between the pronouns. As an offshoot of this student science project, we designed a brief follow-up survey to gain insight into domains and consensus and variation among the students’ perceptions of pronoun mixing. This follow-up survey revealed that if not explicitly asked, most students do not notice pronoun mixing. We asked students to rank four real-life examples of address pronoun mixing that they had gathered during the student science project. We expected that with respect to their perception of the mixing of address pronouns all students would rank examples of mixing in the same order. A primary result of this part of our exploration was that there were large individual differences in the perception of mixing and that there was variation in the ranking of examples among the students. Intersentential mixing yielded the most neutral evaluations by the students, but intrasentential mixing showed the most extreme evaluations. It was disliked most strongly by students who had a general dislike of mixing and liked best by students who appreciated mixing as a style. Briefly switching to V in contexts associated with the T-pronoun was perceived to be humorous by a quarter of the students, and half of the students perceived a switch to the petrified abbreviation AUB (‘if you-V please’) as expressing urgency.

In academic discourse, interactivity has long been conceptualized as a defining feature of digital journalism, offering the potential to transform passive readers into active participants. However, the actual demand for interactive functionalities among audiences—particularly in rapidly evolving digital environments—remains underexplored. This study investigates how Ukrainian digital media users perceive various interactive features and identifies factors influencing their level of interest and engagement. Based on a survey of 401 respondents, the analysis focuses on patterns of media consumption, social media behavior, and attitudes toward different forms of interactivity. The findings indicate a strong preference for low-effort interactivity, such as quizzes, infographics, and simple reaction-based features. In contrast, participatory features that imply deeper editorial collaboration—such as submitting content or suggesting corrections—attract limited audience interest. By comparing user preferences with prior research on the implementation of interactivity in Ukrainian digital media, the study reveals a structural mismatch between audience expectations and editorial practice. These findings underscore the need to reorient interactive design in digital journalism—from normative assumptions toward empirically grounded user preferences—to enhance audience engagement.

In this paper, we study the problem of uniqueness of fixed points for operators acting from a Banach space X into a subspace Y with a stronger norm. Our main objective is to preserve the expected regularity of fixed points, as determined by the norm of Y, while analyzing their uniqueness without imposing the classical or generalized contraction condition on Y. The results presented here provide generalized uniqueness theorems that extend existing fixed-point theorems to a broader class of operators and function spaces. The results are used to study fractional initial value problems in generalized Hölder spaces. Full article
