Most existing log parsers are static. When parsing logs with a static parser, the accuracy tends to fluctuate significantly. To overcome this issue, this paper proposes a dynamic log parser named DLogParser. The core idea of DLogParser is to select different parsing policies based on log features. DLogParser first parses a small batch of sample log messages, then analyzes log characteristics from the parsing results, and determines an appropriate parsing policy for the current logs. Then it parses all remaining logs according to the determined policy. To support dynamic parsing policies, DLogParser incorporates 5 grouping criteria for log features, including length, punctuation, first token, last token, and key token, and establishes 7 rules for parsing policy generation. We evaluated DLogParser on public datasets from LogHub. The experimental results demonstrate that compared to 11 existing log parsers, DLogParser achieves an accuracy of 90.3% with an acceptable performance loss. Full article

This study presents a systematic literature review to examine how the axiological values associated with cultured meat influence consumer perception, using the phenomenology of perception as an analytical framework. Fifty-four peer-reviewed qualitative and quantitative studies, identified through the Libraries Worldwide database, were analyzed using NVivo 12 software, based on predefined keywords and a rigorous selection grid. The results highlight several groups of axiological values that shape consumer attitudes, including the previously unexplored “axiological value of co-production” of cultured meat. Specifically, “dogmatic co-production” (e.g., religious or cultural co-production) appears to significantly enhance consumer perception and acceptance of cultured meat. The main limitation of this study lies in the absence of primary phenomenological field data, which may introduce researcher subjectivity inherent in qualitative paradigms. Nevertheless, the use of existing empirical studies ensures the relevance and reliability of this review. This research offers practical implications for communication strategies, suggesting that aligning messages with key axiological values and their amplifiers, particularly those related to co-production, can strengthen trust in and acceptance of cultured meat. For industry stakeholders, these findings provide guidance for value-driven positioning aimed at increasing consumer confidence. Academically, the study offers a novel perspective by integrating axiological analysis with phenomenology in the context of food technology adoption. Socially, it helps identify consumer concerns and expectations regarding the axiological values perceived as essential for the acceptance of cultured meat. The study’s originality lies in its application of phenomenological analysis to axiological frameworks and in highlighting the central role of co-production, particularly dogmatic co-production, in shaping consumer perception.

This paper examines the effects of AI-based digital nudges on consumers’ sustainable purchase intentions and behaviors, using an integrated framework that combines the Technology Acceptance Model (TAM) and the Nudge Theory. Previous studies have demonstrated that digital nudges can stimulate eco-friendly behavior. However, the interaction between personalization, timing, message framing, cognitive variables like perceived usefulness, and psychological variables such as environmental concern has not been explained. The study employs quantitative research based on SEM-PLS, which explores the relationships between these constructs with a valid response of 810 samples. Personalization, timing of nudges, and framing enhance perceived utility and sustainable purchase intention. Perceived usefulness mediated the relationship between digital nudging and sustainable purchase intention, moderated by environmental concern as a psychological catalyst. These results support the validation of the combined TAM Nudge model, illustrating the role of technology and behavior in fostering sustainability. The implication of the study can support policymakers, marketers, and digital designers in creating ethical AI-based interventions to meet SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action), transforming sustainability awareness into a quantifiable behavioral change.

In 2016, the South African government approved free oral PrEP distribution among high-risk groups like female sex workers (FSWs) to reduce new HIV infections. Despite the availability, unique barriers exist that challenge PrEP persistence, including limited knowledge, side effects, stigma, and mobility that hinder adherence. As such, engaging FSWs in the design of an FSW-led intervention program is crucial to promote PrEP uptake, adherence, and retention. Processes of an intervention mapping approach were applied to design and develop the program in KwaZulu-Natal, South Africa. A needs analysis was completed through existing literature and through engagements with FSWs, FSW peer educators, and a healthcare provider. The working group, comprising eight FSW peer educators and a researcher, co-created the intervention following a six-step mapping process. A total of six meetings took place, during which intervention determinants, change objectives, theory-based methods, and the intervention program were discussed and formulated, as well as implementing partners and the evaluation plan identified. The program focuses on the development of agency, self-efficacy, and hope among FSWs and aims to destigmatize PrEP through positive messaging, equipping FSWs with the ability to differentiate PrEP from ARVs given to people living with HIV. Through role-playing, participants will practice discussing PrEP with their intimate partners and friends, receive suggestions on managing pill supply and side effects, and be equipped to become PrEP ambassadors. The introduction of PrEP as a pill for high-risk groups can be stigmatizing. Therefore, it is crucial to involve marginalized groups in the design and implementation of their interventions to foster acceptance and develop a sense of ownership, ensuring the programs’ sustainability.

Postpartum depression (PPD) affects up to 15% of mothers, yet access to preventive psychological interventions during pregnancy remains limited. Acceptance and Commitment Therapy (ACT) has demonstrated efficacy in promoting psychological flexibility and preventing mental distress. Nevertheless, no studies have yet evaluated its use for the prevention of PPD through a chatbot-based digital intervention. The present study describes the development and preliminary evaluation of an ACT-based chatbot intervention (REA) to support women during late pregnancy and the early postpartum period. Nineteen participants interacted with the low-fidelity REA prototype, explored its features, completed two questionnaires, and then participated in semi-structured interviews. Quantitative data were analysed using the Wilcoxon signed-rank test; qualitative data were analysed using thematic analysis. Quantitative analysis revealed significantly elevated scores for the majority of variables, including empathy and listening, fluency, lexicon, clarity, engagement, functionality, aesthetics, information, and perceived impact. The interview findings demonstrated a notable level of appreciation for the intervention. The participants described the chatbot as engaging and supportive, highlighting a smooth interaction flow, content-appropriate language, and messages of suitable length. The REA prototype demonstrated high acceptability, usability, and perceived usefulness among a diverse range of stakeholders, thus supporting its potential as a scalable, stigma-reducing tool for the prevention of PPD. Subsequent research endeavours will focus on refining the chatbot’s personalisation features and conducting comprehensive clinical trials to evaluate its efficacy. Full article

Artificial intelligence (AI) is increasingly used in marketing to deliver personalized messages and services. Although such tools create new opportunities, their acceptance by consumers depends on several factors that go beyond technology itself. This study examines how trust and ethical perceptions, familiarity and exposure to AI, digital consumer behavior, and identity concerns shape acceptance of AI-based personalized advertising. The analysis draws on data from 650 Greek consumers, collected through a mixed-mode survey (online and paper), and tested using logistic regression models with demographic characteristics included as controls. The results show trust and ethical perceptions of acceptance as factors, while familiarity with AI tools also supports positive attitudes once trust is established. In contrast, digital consumer behavior played a smaller role, and identity-related consumption was negatively associated with acceptance, reflecting concerns about autonomy and self-expression. Demographic factors, such as age and income, also influenced responses. Overall, the findings suggest that acceptance of AI in marketing is not only a technical matter but also a psychological and social process. This study highlights the importance for firms to build trust, act responsibly, and design personalization strategies that respect consumer identity and ethical expectations. Full article

Public acceptance remains a critical barrier to the adoption of genetically modified (GM) foods. This study investigates whether communication strategies that establish different forms of technological legitimacy, specifically regulative, normative, and cognitive legitimacy, can effectively overcome this barrier. Using the contingent valuation method (CVM) with a nationally representative sample of 1194 individuals, this study examined the effect of communication strategies on Chinese consumers’ willingness to pay for GM soybean oil. The results revealed a striking asymmetry. Information emphasizing the safety regulations of GM foods, which aims to build regulative legitimacy, significantly reduced WTP, likely by activating consumer anxieties. Conversely, narratives highlighting technology’s role in ensuring national food security, which builds normative legitimacy, effectively increased WTP for domestic GM oil. Information about the advanced level of GM technology, intended to establish cognitive legitimacy, had no significant impact. The effects were heterogeneous. Females and less knowledgeable consumers were most sensitive to safety messages. Our findings demonstrate that building legitimacy through normative appeals to collective welfare is more effective than relying on regulatory assurances. This study provides a legitimacy-based framework for understanding public perception and offers policymakers crucial insights for communicating about controversial agricultural technologies.

Background: Maintaining daily optimal dental hygiene, especially in medically vulnerable patients with periodontitis, remains challenging in dental practice. Mobile apps and other digital tools might offer useful support alongside traditional advice. Objectives: This study aimed to develop a mobile health app, PerioSupportPro, that helps patients improve their daily plaque control habits. It also reports on the pilot testing of the app’s usability and users’ perception in a small patient group. Methods: The app was created by a mixed team including periodontists, psychologists, developers, and data protection specialists. The first version included reminders, gamified elements, video tutorials, and motivational messages. After internal testing, a group of 18 patients tested the app and completed a feedback questionnaire that assessed usability (Q3–Q5), educational impact (Q6–Q8), motivation (Q9–Q11), and overall satisfaction (Q12–Q14). Cronbach’s alpha was used to check internal consistency, and non-parametric tests were applied for basic statistical comparisons. Results: The motivation section of the questionnaire showed acceptable consistency (α = 0.784), while usability and educational impact had lower values (α = 0.418 and 0.438). No clear differences were found between age groups. Satisfaction was positively associated with reminders and motivational items. Most appreciated features included reminders, the simple interface, and short videos. Based on the input provided by the questionnaire, a few improvements were made, and a second version of the app was prepared. Conclusions: Early user responses show that PerioSupportPro may help motivate and guide patients in their oral hygiene routine. While still in an early phase, the app seems well-received and ready for future clinical validation with more users. Full article

Health misinformation across digital platforms has emerged as a critical fast-growing challenge to global public health, undermining trust in science and contributing to vaccine hesitancy, treatment refusal and heightened health risks. In response, this study introduces Impact, a novel simulation framework that integrates agent-based modeling (ABM) with large language model (LLM) integration and retrieval-augmented generation (RAG) to evaluate and optimize health communication strategies in complex online environments. By modeling virtual populations characterized by demographic, psychosocial, and emotional attributes, embedded within network structures that replicate the dynamics of digital platforms, the framework captures how individuals perceive, interpret and propagate both factual and misleading health messages. Messages are enriched with evidence from authoritative medical sources and iteratively refined through sentiment analysis and comparative testing, allowing the proactive pre-evaluation of diverse communication framings. Results demonstrate that misinformation spreads more rapidly than factual content, but that corrective strategies, particularly empathetic and context-sensitive messages delivered through trusted peers, can mitigate polarization, enhance institutional trust and sustain long-term acceptance of evidence-based information. These findings underscore the importance of adaptive, data-driven approaches to health communication and highlight the potential of simulation-based methods to inform scalable interventions capable of strengthening resilience against misinformation in digitally connected societies.

Animal fur has long symbolized luxury and social status, but growing concerns about animal welfare, environmental harm, and zoonotic disease risks have prompted global reforms, with over 22 countries banning fur production. In the United States, however, public attitudes toward fur farming and sales bans remain underexplored. This study surveyed 2014 adults from Connecticut, Massachusetts, New Jersey, and New York to assess views on fur farming, acceptability, and support for state-level bans, as well as the influence of message framing. Participants were randomly assigned to one of six message conditions (animal welfare, environmental, public health, economic, faux fur alternatives, or social norms) or a control group. Most respondents supported bans on fur sales and fur from commercial farms (approximately 65% weighted). Messages highlighting animal welfare, environmental impacts, public health, and social norms significantly increased support, while economic and faux fur messages did not. Political affiliation moderated these effects, with independents most responsive. Beliefs about cruelty, environmental harm, and zoonotic risks predicted support, whereas conservatism, opposition to regulation, and consumer rights beliefs predicted opposition. Overall, appeals to ethics, sustainability, and social change appear most effective for advancing fur-related policy initiatives. Full article

Introduction: Mpox emerged as a multi-country outbreak in 2022 and disproportionately affected gay, bisexual, and other men who have sex with men (GBMSM). Stigma is known to exacerbate health crises by discouraging testing, treatment, and vaccination. This review aimed to explore stigma associated with Mpox among GBMSM from July 2022, when mpox was declared a public health emergency of international concern. Methods: The PICO framework guided this narrative review. A search was conducted across the following databases from inception to June 2025: PubMed/MEDLINE, Embase, CINAHL, and Web of Science. The literature had to be empirical, peer-reviewed research that focused on mpox-related stigma in GBMSM. Results: Forty-seven studies were included in this review. The following themes were derived: (1) healthcare experiences, (2) media influence, (3) internalised and anticipated stigma, (4) public health messaging, (5) community responses, and (6) psychosocial impact. Healthcare experiences were marked by anticipated discrimination; many GBMSM delayed testing or vaccination for fear of being disclosed or labelled promiscuous. This was especially apparent in contexts where same-sex relationships are criminalised, leading some men to self-medicate or seek clandestine services. Media analyses revealed that social and traditional platforms often amplified blame and homophobia, though community-led counter-messaging helped shift narratives. Internalised and anticipated stigma resulted in shame, concealment of symptoms, avoidance of care, and heightened anxiety. Public health messaging that framed mpox as a behaviour-linked rather than identity-linked risk was more acceptable, and flexible vaccination strategies (e.g., offering less conspicuous injection sites) increased uptake. Stigma contributed to psychosocial distress and may have impeded outbreak control. Conclusions: Mpox-related stigma among GBMSM operates at individual, community, and structural levels, echoing patterns from the HIV era. Effective mitigation requires rights-based, destigmatising communication, culturally competent care, and collaboration. Addressing stigma is vital to controlling future outbreaks and ensuring equitable healthcare access. Full article

Background: Migrant populations are commonly under-immunised relative to general populations in host countries. The evidence base on routine vaccination among migrant children suggests that higher priority is given to infants and younger children compared to adolescents. Though migrants are often classified as a homogenous group, different sub-populations of migrants exist, including voluntary migrants who choose to move and involuntary migrants forcibly displaced by humanitarian crises. The human papillomavirus (HPV) vaccine, a relatively recent addition to global routine immunisation schedules for adolescents, is a useful proxy for understanding vaccine equity for this under-prioritised group. This qualitative systematic review explores health system determinants of delivery and uptake of HPV vaccination services among involuntary migrants. Methods: A literature search was conducted across ten electronic databases. An analytical framework tailored to the migrant context aided in capturing the complexity and magnitude of systemic factors that determine vaccine delivery and uptake among involuntary migrants. Of the 676 records retrieved, 27 studies were included in this review. Results: Key determinants of vaccine delivery include adaptation of immunisation policies for migrant inclusiveness, implementation of migrant-targeted interventions, health provider recommendations, electronic health records, and free vaccines. Uptake determinants include access dependent on legal status, awareness-related determinants akin to culturally appropriate health messaging, and acceptance-related determinants associated with sociocultural beliefs, misinformation, and distrust. Conclusions: Prioritising vaccination programmes linked with non-outbreak-related diseases is challenging in the disruptive context of humanitarian crises given fragile health systems, limited resources, loss of health infrastructure and deployment of health personnel to emergency care. We strongly advocate for global actors at all health systems levels to actively reform national HPV vaccination programmes to enhance inclusivity of adolescent girls in crises settings or resettled in host countries.

Vehicular Ad Hoc Networks (VANETs) support safety-critical and traffic-optimization applications through low-latency, reliable V2X communication. However, securing integrity and auditability with blockchain is challenging because conventional BFT-style consensus incurs high message overhead and latency. We introduce CoCoChain, a concept-aware consensus mechanism tailored to VANETs. Instead of exchanging full payloads, CoCoChain trains a sparse autoencoder (SAE) offline on raw message payloads and encodes each message into a low-dimensional concept vector; only the top-k activations are broadcast during consensus. These compact semantic digests are integrated into a practical BFT workflow with per-phase semantic checks using a cosine-similarity threshold $\theta =0.85$ (calibrated on validation data to balance detection and false positives). We evaluate CoCoChain in OMNeT++/SUMO across urban, highway, and multi-hop broadcast under congestion scenarios, measuring latency, throughput, packet delivery ratio, and Age of Information (AoI), and including adversaries that inject semantically corrupted concepts as well as cross-layer stress (RF jamming and timing jitter). Results show CoCoChain reduces consensus message overhead by up to 25% and confirmation latency by 20% while maintaining integrity with up to 20% Byzantine participants and improving information freshness (AoI) under high channel load. This work focuses on OBU/RSU semantic-aware consensus (not 6G joint sensing or multi-base-station fusion). The code, configs, and an anonymized synthetic replica of the dataset will be released upon acceptance. Full article

Background/objectives: Alcohol use during pregnancy can result in adverse outcomes for the offspring, including Fetal Alcohol Spectrum Disorders (FASD). Psychosocial and contextual factors may influence gestational alcohol intake and women’s risk perception. This systematic review aimed to assess pregnant women’s and women of childbearing age’s perceived risk of alcohol use during pregnancy and to evaluate their knowledge of its potential effects on children. Methods: Following the PRISMA guidelines, a systematic search was conducted in Web of Science, PubMed and PsycArticles databases for studies published up to May 2025. Eligible studies examined gestational alcohol use, risk perception, or knowledge of fetal consequences among pregnant women or women of reproductive age. Methodological quality was assessed with the Critical Appraisal of Qualitative Studies tool from the Centre for Evidence-Based Medicine (CEBM). Results: Twenty-nine studies were included. Reported prevalence of alcohol consumption during pregnancy varied considerably across settings. A substantial proportion of women perceived alcohol use during pregnancy as acceptable, often depending on quantity, frequency, type of beverage, or stage of gestation. Knowledge of FASDs was generally limited and frequently restricted to physical malformations. Misconceptions were more common among women with prior alcohol use. The findings highlight persistent gaps in risk perception and knowledge about FASDs. Conclusions: Prevention strategies should not be limited to pregnant women but should also target women of childbearing age, especially those with active drinking patterns, as well as their immediate sociocultural environment. Strengthening professional training, community-based interventions, and consistent public health messaging are essential to reduce gestational alcohol exposure. Full article

The interconnection between health and environment is increasingly recognised, as is the role of healthcare professionals in raising awareness among patients and healthcare policymakers. To explore the relevance of enhancing patients’ awareness of the links between health and environment in ambulatory care, we conducted a qualitative study on General Practitioner (GP) practices in Switzerland. Using a co-benefit approach, we designed materials on meat consumption and active mobility, which were displayed in the waiting rooms. We conducted observations in five practices and interviewed five patients and five GPs to examine patients’ understanding of the messages and assess the acceptability of discussing them during medical encounters. Patients and GPs were receptive to the co-benefit approach. However, barriers were identified in promoting co-benefits during clinical encounters, including time constraints and lack of knowledge. Patients showed reactance to the messages and questioned the reliability of messages related to climate change. GPs were reluctant to compromise relationships with patients and were ambivalent, viewing environmental discussions as political. Positive message display and community promotion were identified as facilitators. This study highlights the need to develop clear educational materials to support GPs, to adapt messages to patients’ backgrounds, and to address the dichotomy between GPs’ political and scientific perspectives.
