The Central Appalachian region, where family forest landowners (FFLs) control much of the carbon sequestration potential, holds the potential for forest-based climate solutions. Despite this, participation in carbon offset programs remains low, largely due to the disconnect between small landowner needs and program structure. This study examines FFL preferences for carbon programs in Central Appalachia. Utilizing a panel-data mixed logit model, we evaluated the effects of contract length, payment amount, harvest requirements, and program administration on participation decisions. Our results indicate that higher payments significantly increase program participation. Furthermore, contract lengths of at least 15 years and restrictive harvests negatively influence program participation. Program administration played a significant role, with government-administered programs being less preferred, with odds 48% lower than privately administered programs. Landowner characteristics such as carbon-oriented ownership, education, and income also influence participation. The willingness-to-accept analysis shows high compensation demands for less favorable terms: $107–$397/ha/year for longer contracts and $104–$173/ha/year for harvest restrictions. Additionally, landowners require an extra $66/ha/year for government administration. The findings underscore the importance of designing carbon offset programs that are flexible, offer adequate compensation, and foster trust, while aligning with landowners’ management objectives.

Background: Trust in information sources is essential to enhance an individual’s understanding of the message and boost their willingness to change or act on specific health behavior, including vaccine uptake. This study explores the association between trust in information sources and parents’ knowledge, attitudes, and practices regarding their children’s 13-valent pneumococcal conjugate vaccine (PCV13) uptake across seven cities in the Yangtze River Delta (YRD) region in China. Methods: A cross-sectional web-based survey was conducted from May to June 2023. Adult parents (N = 1304) who had at least one child aged 24 months or less and lived in the YRD region were recruited. The Adjusted Ordinary Least Squares (OLSs) regression model was applied to estimate the association between participants’ level of trust in different information sources and their knowledge, attitudes, and practices of children’s PCV13 vaccination. Results: Information from the Disease Control and Prevention Center (CDC) source received the highest trust score. Age, gender, education, and annual household income were related to varied trust levels in specific sources. Trust in the health service provider source was significantly associated with a better command of PCV13 knowledge, acceptance of PCV13, and a higher likelihood of vaccination. Trust in online community sources was positively associated with vaccine uptake. Conclusions: The study participants highly trusted information from health service provider sources. These sources may be effective channels with potential to enhance parents’ vaccine knowledge and acceptance of PCV13. Public health workers could utilize trusted sources to disseminate the benefits of the PCV13 and encourage the uptake of the vaccine. Full article

This study investigates the public acceptance and willingness to pay (WTP) for nuclear energy in Saudi Arabia, a country seeking to diversify its energy portfolio under Vision 2030. Utilizing a cross-sectional survey of 403 residents, the research employs descriptive statistics, regression analysis, and a SWOT analysis to explore the socio-economic and perceptual drivers of public attitudes. The findings reveal that 82.4% of participants support nuclear energy, with a mean WTP of 38.2% of their monthly electricity bill for its development. Key factors positively influencing acceptance include age and knowledge about nuclear energy, while environmental concerns and being married are associated with lower support. Notably, trust in government oversight (64.8%) and the prospect of a new energy source (62.7%) are major reasons for support, whereas health and environmental risks (74.6%) are the primary concerns for opponents. This study provides crucial, evidence-based insights for policymakers, marking the first Saudi-specific research to jointly examine WTP, acceptance determinants through econometric modeling, and strategic implications via SWOT analysis, highlighting the need for targeted public engagement and transparent communication strategies to address public concerns and ensure the successful and sustainable integration of nuclear energy into Saudi Arabia’s energy mix.

By 2030, the world population is projected to reach approximately 9.7 billion. One of the core objectives of the global sustainable development goals (SDGs), adopted from the 1996 World Food Summit, is to eradicate hunger by that time, meaning ensuring food security for all. The Food and Agriculture Organization (FAO) defines food security as follows: “Food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life.” Conceptually, it is posited that food security can be understood as a nexus of four elements: Food security = Availability + Access + Utilization + Stability of a food system. This study focused specifically on the food availability component of food security. It addresses a critical gap in the existing literature: the limited understanding of the role farmworkers and their families play in sustaining food systems. Specifically, it explores how the children of Haitian farmworkers in the United States perceive agricultural labor through the lens of their family’s experiences, including their personal willingness to engage in it and their advocacy for others to pursue such work. Although qualitative in nature, this study employed the Political Economy of the Food System, also referred to as Agrifood Systems Theory or the Political Ecology of Food Systems, as its guiding theoretical framework, as it aligns closely with the study’s objectives. The data were collected between December 2022 and June 2023. The sample consisted of eight young adults (ages 18 to 29), all of Haitian descent. Overall, the findings indicated that participants commonly reported feeling a sense of inferiority and a lack of interest in and respect for farmwork as a profession during their upbringing, particularly in comparison to peers from non-farmworker households and those outside of their immediate communities. This sense of inferiority was attributed to several factors, including their upbringing, the inherent vulnerability associated with farm work, and the long-term physical toll agricultural work had on both themselves and their parents. The study’s findings carry important implications for practitioners, scholars, policymakers, and all stakeholders involved in achieving food security. They underscore the urgent need to reform labor policies and improve the conditions surrounding farm work, making it a more appealing, dignified, desirable, and sustainable occupation in the face of a growing world population.

Electric vehicles (EVs) and thermostatically controlled loads (TCLs) are key demand-side resources for load regulation in modern power systems. However, effective load regulation faces significant challenges due to the stochastic nature of EV travel times and environmental uncertainties, such as temperature and solar irradiation fluctuations affecting TCL performance. Additionally, load rebound effects, caused by TCLs increasing power consumption to restore preset indoor temperatures after regulation, may induce secondary demand peaks, thereby offsetting regulation benefits. To address these challenges, this study aims to meet regulation requirements under such uncertainties while mitigating rebound-induced peaks. A rolling-horizon co-optimization method for EV and TCL clusters is proposed, which explicitly considers both uncertainties, load rebound effects and economic losses. First, to address the limited regulation capacity of individual EVs and TCLs, a user clustering mechanism is developed based on willingness to participate in demand response across multiple time intervals. A load rebound evaluation model for TCL clusters is developed to characterize post-regulation load variations and assess the rebound intensity. Subsequently, a load rebound-aware co-optimization model is proposed and solved within a rolling-horizon optimization approach, which performs rolling optimization within each prediction horizon to determine the participating clusters and their regulation capacities for each execution time slot under uncertainties. Simulation results demonstrate that the proposed method, compared with conventional day-ahead and robust optimization, not only meets load regulation requirements under uncertainty, but also effectively mitigates rebound-induced secondary peaks while achieving economic benefits.

This paper examines the sexual and reproductive health (SRH) knowledge, experiences, service access, and unmet needs of Rohingya adolescent refugee girls living in the camps of Cox’s Bazar, Bangladesh. The refugee population in these camps is approximately 1.3 million, with more than half under the age of 18 and girls representing over one quarter of the total. Given the growing proportion of adolescent girls, SRH knowledge and service provision are critical both for the refugee community and for Bangladesh’s broader sustainable development goals. Drawing on direct accounts from adolescent girls and insights from community-based key informants, this research explores levels of SRH awareness, willingness to seek care, encounters with sexual violence, understanding of sexually transmitted diseases, and reproductive health priorities. It also identifies barriers to service delivery faced by healthcare and humanitarian providers. The findings highlight how cultural norms, social constraints, and religious beliefs intersect with structural barriers—including lack of education, financial dependence, gender-based violence, and the need for parental or spousal consent—to restrict access to SRH services. Despite these challenges, some participants reported successfully receiving reproductive health care. This paper calls for coordinated action from the government, humanitarian agencies, and social service organisations to improve both the availability and accessibility of SRH services for adolescent refugee girls. Strategies should include enhanced outreach, culturally responsive engagement, and sustained follow-up care to promote safety, dignity, and well-being within the camps. Full article

Digital pollution, encompassing energy consumption, e-waste, and the environmental impact of digital technologies, poses a significant and increasingly pressing environmental challenge that has received insufficient research attention. This study explores public perceptions, attitudes, and behaviors related to digital pollution, focusing on both individuals’ willingness to pay for environmentally friendly digital solutions and their actions to reduce digital environmental impact. Through a comprehensive survey of 300 UK participants, we examined the associations between demographic factors, knowledge levels, perceptions, and environmental actions. While traditional demographic factors such as age and income showed no significant correlation with willingness to pay, we found strong positive correlations with the frequency of environmental consideration (r = 0.47), willingness to act (r = 0.42), and perceived importance of digital pollution (r = 0.40). Notably, knowledge of digital pollution was not correlated with willingness to pay, while self-assessed tech-savviness and environmental knowledge had positive correlations with both willingness to pay and actions taken. Based on a robust cluster analysis, we identified four distinct participant groups: ’Engaged Eco-Tech Enthusiasts’ (youngest, most tech-savvy, and with the highest willingness to act), ‘Knowledgeable Traditionalists’ (oldest, highest knowledge scores, and moderate action), ‘Unengaged Pragmatists’ (lowest engagement), and ‘Affluent Moderates’ (wealthiest and with moderate engagement). These findings provide valuable insights for developing targeted interventions and communication strategies to address this emerging environmental challenge. Full article

Background/Objectives: There is growing interest in non-diet approaches to support health, well-being, and performance in different populations. The aim of this study was to evaluate the effects of a 12-week intuitive eating (IE) intervention on participants’ body composition, body image, eating behaviors, and athletic performance. Methods: The study included both an intervention group and a control group. It was conducted between September and December 2021. Participants were recruited from a sports center in Istanbul, where they had applied for nutrition and exercise counseling. Inclusion criteria included being 18–65 years old, not having engaged in regular physical activity in the past month, having no chronic disease, and not using any regular medications. Participants were not randomly assigned to groups; allocation was based on availability and willingness to attend the intervention sessions. The study involved 57 participants who were healthy adults between 18 and 65 years old and followed a structured exercise program. At the beginning of the study, a demographic questionnaire was administered. The anthropometric measurements were taken at the beginning and at the end of the intervention. In addition, validated performance and psychometric assessment tools were used, including the Cooper test for cardiovascular endurance, the Davies test for upper-body agility, and the 1-RM bench press for muscular strength, alongside standardized self-report questionnaires for eating attitudes (EAT-26), IE (IES-2), and body image (BCS). Results: The intervention group did not show any statistically significant changes in body composition (p > 0.05). The post-intervention means of the intervention and control groups were not statistically different (p > 0.05). The intervention group showed significant improvements in cardiovascular endurance, agility, and strength performance scores compared to the control group after the intervention (p < 0.05). The intervention group showed significant improvements in body image scores (p < 0.05) and eating attitude scores (p < 0.05). The post-intervention eating attitude and body image scores of the intervention group were significantly different from those of the control group (p < 0.05). The results of the correlation analysis showed a significant positive correlation between intuitive eating and body image (r = 0.455; p < 0.05) and a significant negative correlation between IE and disordered eating attitudes (r = −0.449; p < 0.05). Conclusions: These findings suggest that longer-term interventions may be beneficial and warrant further investigation. IE may serve as a promising strategy to enhance psychological well-being and performance outcomes without focusing on weight control. Full article

The study investigates the interplay among second language (L2) learners’ willingness to communicate (WTC), L2 self-confidence (L2SC), and academic self-concept (ASC) within a cohort of Vietnamese university students studying in the United Kingdom. Employing an explanatory sequential mixed-methods design, self-reported quantitative data were collected via validated survey instruments (n = 32 students), followed by semi-structured interviews with a purposive subsample (n = 5 students) to contextualise the findings. Results revealed that participants exhibited moderate levels of WTC and L2 self-confidence, alongside emerging academic self-concept. Significant positive correlations were observed between WTC and L2 self-confidence and between L2 self-confidence and academic self-concept; a weak, non-significant association was found between WTC and academic self-concept. Qualitative data corroborated these patterns, highlighting how learners’ communicative confidence was shaped by supportive environments and evolving self-perceptions. While self-comparisons and cultural expectations occasionally influenced students’ academic self-concept, most participants reported resilience and a commitment to communication development. The study contributes to the literature by integrating psychological and contextual variables influencing WTC, offering pedagogical implications for enhancing communicative competence among international English as a second language learners.

Growing environmental challenges and the need to practice sustainable human actions and attitudes make it necessary to search for new solutions that can minimize the negative impact of human activity on the environment. This also refers to the tourism industry. In this article, the authors propose the use of virtual reality (VR) to visit any destination worldwide as a potential green alternative to traditional forms of travel. The aim of this study presented in this article was to analyze public acceptance and user perceptions of VR as a tool supporting or replacing real-world tourism. This study involved 215 people who used the Google Earth VR application to visit their chosen destinations around the world. Respondents also completed a two-part survey (before and after the VR experience), in which they assessed, among other things, the realism of the VR visiting and the overall VR experience and expressed their opinions on the role of VR in tourism. The results indicate that while VR is not yet widely recognized as a full-fledged substitute for travel (46% of respondents stated that VR would not replace real travel but could be a good complement), it was rated as useful for people who cannot travel (79.1% of respondents) and before trips (79.1% of respondents). The realism of the Google Earth VR application received an average rating of 3.679 on a scale of 1 to 5, with a median of 4. This study addresses the yet unexplored area of VR in tourism, which has great potential given that the results show a quite positive attitude of participants towards using the application enabling virtual travel—nearly three-quarters of the sample (73.9%) expressed a willingness to return to VR-based sightseeing experiences.

Background/Objectives: Standard dental practice is being reshaped by digital technologies, and artificial intelligence (AI) is emerging as one of the most challenging recent innovations. Methods: The present study assessed the interest of Romanian dentists in the integration of AI into their current practice through an anonymous questionnaire distributed to 200 respondents. The questionnaire addressed the integration of AI in dentistry by analyzing the following areas of intervention: stages of patient care, perceived impact on the doctor–patient relationship, data security, implementation costs, and the legislative framework. Results: The results showed that 53.6% of dentists reported low difficulties, 37.3% reported moderate difficulties, and 9.1% reported high difficulties with using digital tools. Dentists’ reported willingness to adopt AI-based solutions was as follows: 58.6% were very willing, 30% were moderately willing, and only 11.4% were not very willing. Currently, 80.5% already use digital techniques in their daily practice. The participants emphasized the need to maintain a strong doctor–patient relationship while recognizing the benefits of increased efficiency. They were aware of the risk of diminishing human connection and trust. Also, data security and the financial stress associated with implementing and maintaining new systems were seen as major obstacles. Conclusions: The dentists surveyed showed an increased interest in modern digital technologies, provided that there is a clear legal framework, a strong data protection system, and the preservation of the doctor–patient relationship based on trust and confidentiality that defines the medical profession.

Objectives: Hepatitis E virus (HEV) infection is associated with severe hepatitis and high mortality rates, yet vaccination coverage remains suboptimal. Investigating public preferences for HEV vaccination is critical for developing targeted prevention strategies. This study employed a discrete choice experiment (DCE) to quantify attribute preferences and willingness-to-pay (WTP) for HEV vaccination among Chinese residents (in Shaanxi Province, for example), aiming to inform evidence-based immunization policy optimization. Methods: A cross-sectional survey recruited 3300 participants using stratified random sampling. The vaccine attributes—protective efficacy, duration of protection, and out-of-pocket cost—were identified using a systematic literature review and expert consultation. A comparative analysis of preference characteristics was conducted using conditional logit (Model 1) and mixed logit (Model 2) regression models. Population heterogeneity in vaccination preferences was further analyzed using the conditional logit framework, with marginal WTP estimated using parameter coefficients. Results: Among 3199 valid responses, duration of protection (Model 2: 10-years; β = 0.456, p < 0.001) and out-of-pocket cost (Model 2: 2000–3000 CNY; β = −0.179, p < 0.001) significantly influenced vaccination decisions. Preference heterogeneity was observed: women of childbearing age prioritized longer protection (10 years; β = 0.677, p < 0.001) and were sensitive to the cost of 1000–2000 CNY (β = 0.169, p = 0.011), while urban residents valued extended protection more than rural counterparts. Conclusions: Protection duration emerged as the primary determinant of HEV vaccination preference. Policy recommendations include implementing tiered pricing strategies and targeted health education campaigns emphasizing long-term protection benefits to enhance vaccine uptake and affordability.

Against the backdrop of the growing popularity of blockchain technology, this study investigates blockchain adoption strategies for the fresh food supply chain (FFSC) under a carbon cap-and-trade (CAT) policy. Taking a two-echelon supply chain consisting of a supplier and a retailer as an example, we designed four blockchain adoption modes based on the supplier’s strategy (adopt or not) and the retailer’s strategy (adopt or not). Combining influencing factors such as consumers’ low-carbon preference, consumers’ freshness preference, and carbon trading price (CTP), we established four game-theoretic models. Using backward induction, we derived the equilibrium strategies for the supplier and retailer under different modes and analyzed the impact of key factors on these equilibrium strategies. The analysis yielded four key findings: (1) BB mode (both adopt blockchain) is the optimal adoption strategy for both FFSC parties when carbon prices are high, and consumers exhibit strong dual preferences. It most effectively mitigates the negative price impact of rising carbon prices by synergistically enhancing emission reduction efforts and freshness preservation efforts, thereby increasing overall profits and achieving a Pareto improvement in the benefits for both parties. (2) Consumers’ low-carbon preference and freshness preference exhibit an interaction effect. These two preferences mutually reinforce each other’s incentive effect on FFSC efforts (emission reduction/freshness preservation). Blockchain’s information transparency makes these efforts more perceptible to consumers, forming a synergistic “emission reduction-freshness preservation” cycle that further drives sales and profit growth. (3) The adoption of blockchain by either the supplier or the retailer significantly lowers the cost threshold for the other party to adopt blockchain, thereby increasing their willingness to adopt. (4) CAT and consumer preferences jointly influence the adoption strategies of suppliers and retailers. Additionally, the adoption strategies of FFSC participants are also affected by the other party’s blockchain adoption status. Drawing on the above conclusions, this study provides actionable guidance for suppliers and retailers in selecting optimal blockchain adoption strategies. Full article

This study aimed to validate the Robot Acceptance Questionnaire (RAQ), a self-report instrument designed to assess user acceptance toward social robots. Originally structured around four theoretical domains—pragmatic, hedonic (identity and feelings), and attractiveness—the RAQ was empirically found to converge into two robust and inversely related dimensions: Positive Attitude (PA) and Negative Attitude (NA). A total of 208 participants (mean = 43.1; S.D. = 21.4) viewed a short video of a humanoid robot (Pepper) and completed the RAQ. Factorial structure (Principal Component Analysis), internal reliability (Cronbach’s alpha), and construct validity were assessed. Results showed excellent internal consistency for both PA and NA (α = 0.93), and intuitive associations with independent measures of ease of use, mastery, and willingness to interact. The RAQ thus offers a concise and reliable tool for assessing general robot acceptance, especially suitable for remote and large-scale studies. Full article

The field of communication studies shares significant connections with environmental science, where environmental monitoring constitutes one of the fundamental functions of communication. Based on data from the China General Social Survey (CGSS2021), this study establishes two research models and employs ordered logistic regression to examine the relationships between media usage, environmental water pollution, cognition of environmental policies, and willingness to pay (WTP) for environmental protection. The findings reveal that the perception of water pollution significantly enhances public cognition of environmental policies and WTP. However, the impact of water pollution itself is insignificant, indicating a weak public perception of long-term environmental risks. Both traditional media usage and new media usage significantly improve cognition of environmental policies, with traditional media playing a more pronounced role; yet, media trust does not significantly enhance cognition. Furthermore, new media usage and media trust exhibit a negative impact on WTP for environmental protection, revealing the effects of the “clicktivism” mechanism and the “trust-efficacy perception” negative feedback loop. The negative impact of cognition of environmental policies on WTP further uncovers a “cognition-behavior paradox,” where groups with higher cognition tend to attribute environmental responsibility to the government, thereby reducing their personal WTP. Based on these findings, this paper proposes recommendations including optimizing environmental communication strategies, strengthening public participation, and designing differentiated policies to enhance public environmental awareness and promote the effective implementation of water pollution governance.
