To address the autonomous traversability challenge of an Unmanned Articulated Road Roller (UARR) operating on harsh terrains where low-adhesion slipperiness and geometric irregularities are coupled, and traction capacity is severely limited, this paper proposes a Terrain-Adaptive Maximum-Entropy Policy Optimization (TAMPO). A unified multi-physics simulation platform is constructed, integrating a high-fidelity vehicle dynamics model with a parameterized terrain environment. Considering the prevalence of geometric irregularities in construction sites, a parameterized mud-pit model is established—generalized from a representative case—as a canonical physical model and simulation carrier for this class of traversability problems. Based on this model, a family of training and test scenarios is generated to span a broad range of terrain shapes and adhesion conditions. On this foundation, the TAMPO algorithm is introduced to enhance vehicle traversability on complex terrains. The method comprises the following: (i) a Terrain Interaction-Critical Reward (TICR), which combines dense rewards representing task progress with sparse rewards that encourage terrain exploration, guiding the agent to both climb efficiently and actively seek high-adhesion favorable terrain; and (ii) a context-aware adaptive entropy-regularization mechanism that fuses, in real time, three feedback signals—terrain physical difficulty, task-execution efficacy, and model epistemic uncertainty—to dynamically regulate policy entropy and realize an intelligent, state-dependent exploration–exploitation trade-off in unstructured environments. The performance and generalization ability of TAMPO are evaluated on training, interpolation, and extrapolation sets, using PPO, SAC, and DDPG as baselines. On 90 highly challenging extrapolation scenarios, TAMPO achieves an average success rate (S.R.) of 60.00% and an Average Escape Time (A.E.T.) of 17.56 s, corresponding to improvements of up to 22.22% in S.R. and reductions of up to 5.73 s in A.E.T. over the baseline algorithms, demonstrating superior decision-making performance and robust generalization on coupled slippery and irregular terrains.

This study examines the relationship between Wasta—a social network based on family, lineage, tribe, and extended family ties—as practiced by senior HRM employees, and its effects on entrepreneurial creativity, innovation, and sustainable development in the MENA region. The study also explores why entrepreneurs and countries in the MENA region are not ranked among the top 100 innovators in the Global Innovation Index. Additionally, it addresses why Wasta, as practiced by HRM employees, can impede sustainable development. The author drew on Amabile’s Componential Theory of Organizational Creativity and Model of Creativity and Innovation in Organizations. Evidence was gathered from articles on Wasta, secondary data from the Global Innovation Index (GII) for 2023, and the Global Entrepreneurship Monitor (GEM NECI) in 2024. Secondary datasets were analyzed using constant comparative analysis of documents. These datasets included accessible online indices, the Global Innovation Index in 2023, the World’s Most Innovative Companies Index by Forbes, and the Top 100 Global Innovators 2024 Rankings by Clarivate. The study develops a theoretical framework for the link between Wasta and sustainable development. It concludes that Wasta, when practiced by senior HRM employees, is likely a reason why MENA entrepreneurs fall short in achieving sustainable development and why the region’s countries are not among the top 100 innovative countries globally. The study answers why Wasta hinders sustainable development among MENA entrepreneurs. This study recommends that entrepreneurs recognize the importance of fair HRM practices in hiring, supervisor selection, candidate selection, and promotions to foster innovation and sustainable development. The conclusions may also encourage policymakers to create and enforce new rules to reduce Wasta if they aim to stimulate innovation, sustainable development, and economic advantage in the MENA region.

Worldwide the adoption of electric vehicles (EVs) is recognized as a key strategy for reducing transport-related greenhouse gas (GHG) emissions, a major contributor to global warming and climate change. The objective of this pilot study is to examine the key variables that might have influenced electric vehicle (EV) purchase decisions among current EV owners and how they are aligned or different for the prospective EV owners in North Carolina (NC). By adopting a web-based survey for data collection, the study specifically aims to identify economic, demographic, environmental, and commuting behaviors, along with existing government policies and incentives that might motivate consumer choices regarding EV adoption. Most existing EV owners who participated in the survey identified themselves as college-educated White men with USD 100 K or higher income, have more than two cars, commute more than 30 min, and live in single-family homes with EV charging. In contrast, among non-EV owners who plan to adopt an EV within the next three years, a significant proportion are non-White, women, and earn USD 50,000 or less annually. While home charging is important to both current EV owners and non-EV owners, EV incentive policies and proximity to public changing stations are found to be more important to non-EV owners’ decision to adopt EVs. A reasonable conclusion from this research is that expanding EV-friendly policies, incentives, and infrastructure will encourage first-time EV ownership in NC while providing deeper insights into the dynamics of sociodemographic among both EV owners and non-EV owners.

The efforts to achieve early detection of autism spectrum disorders (ASD) are becoming increasingly important due to the high prevalence that continues to persist globally. The World Health Organization (WHO) and other official institutions agree that in marginalized regions, it is urgently necessary to develop effective alternatives and methods to improve the quality of life of children and their families. This study presents an integrated model for the early detection of ASD, based on the analysis of parental observations and supported by validated diagnostic tools. The proposed approach consists of four sequential modules, aiming to improve early detection through techniques such as natural language processing (NLP) and machine learning (ML) metrics. Records from two Latin American countries were standardized, thereby consolidating a single database comprising 153 records of children aged 2 to 6 years. The Parent Interview Instrument (PII) was administered by specialists to caregivers and subsequently compared with standardized tests. Encouraging results were obtained from the support vector machine (SVM) classification algorithm, yielding an accuracy range of 89.88–91.34%, a maximum precision of 90.02%, a recall of 89.02%, and a maximum F-measure of 91.12%. The results of the case study allow us to identify disorders related to autism, such as the repetition of behaviors, difficulties in social interaction, and issues with verbal expression. This contribution aligns with the United Nations Sustainable Development Goal 3, which promotes health and well-being. Full article

Background: Malnutrition is common among older adults with cognitive impairment and contributes to frailty and poorer health outcomes. Many individuals with dementia require mealtime assistance, yet differences in caregiving practices across hospital and nursing home settings remain underexplored. Aim: The aim of this study was to compare eating encouragement practices, feeding skills, feeding difficulties, and nutritional status between family caregivers in hospitals and professional caregivers in nursing homes. Methods: A cross-sectional observational study was conducted between June 2020 and December 2023 in New South Wales, Australia. The study included 82 older adults (≥65 years) with cognitive impairment: 31 hospital patients supported by family caregivers and 51 nursing home residents supported by assistant nurses. Eating encouragement, feeding skills, and feeding difficulties were assessed using structured observation tools, and nutritional status was evaluated using the Mini Nutritional Assessment–Short Form (MNA-SF). Group differences were analysed using chi-square tests and independent t-tests (p < 0.05). Results: Family caregivers in hospitals demonstrated stronger relational and engagement-based practices, including consistent handwashing (χ² = 31.945, p < 0.001), encouraging self-feeding (χ² = 21.678, p < 0.001), verbal cueing (χ² = 12.083, p = 0.002), touch prompting (χ² = 51.817, p < 0.001), and sitting face to face (χ² = 38.697, p < 0.001). Nursing home caregivers showed more advanced technical skills, such as task simplification (χ² = 54.135, p < 0.001), mirroring (χ² = 78.456, p < 0.001), hand-over-hand guidance (χ² = 73.076, p < 0.001), mouth- and lip-opening techniques (both χ² = 81.000, p < 0.001), and stronger choking management (p < 0.001). Feeding difficulties also differed: refusal behaviours were more common in nursing homes, while distraction and oral–motor issues were more frequent in hospitals. Overall, nursing home residents had significantly poorer nutritional status (t = −12.592, p < 0.001). Conclusions: Family caregivers provide stronger relational support, whereas professional caregivers demonstrate superior technical competence. Integrating these complementary strengths may enhance mealtime care and reduce malnutrition among cognitively impaired older adults. Full article

The use of full-battery electric vehicles is an essential strategy for reducing greenhouse gas emissions and mitigating climate change. This study examined the transition to full-battery electric vehicles by conducting a cross-sectional household survey in 2023 that collected information on vehicle preferences, evaluations, purchase intentions, environmental attitudes, and socioeconomic and demographic characteristics. The results show that among households using a vehicle as their primary mode of transportation, approximately 89% relied on fossil fuel vehicles, whereas only 6% used electric vehicles. The study further finds that acceptance of vehicles during inter-vehicle transitions is closely linked to energy type: households currently owning fossil fuel vehicles exhibited a high likelihood of repurchasing a fossil fuel vehicle, while electric vehicle owners were more inclined to choose another electric vehicle across cities and areas of different sizes. Households that own electric vehicles tend to report higher levels of well-being compared with those that own fossil fuel vehicles. In addition, sufficient charging infrastructure, stronger knowledge of environmental issues, participation in altruistic donation activities, and cooperative behavior positively influenced electric vehicle adoption. These findings suggest several policy implications, including the expansion of charging stations for business and public use, setting reasonable vehicle prices, improving charging speed, developing electric vehicles suitable for large families, and encouraging individuals to gain initial driving experience with electric vehicles to promote adoption.

Mothers’ behavior strongly influences children’s eating habits, with family attitudes and feeding practices playing a key role in dietary development. In accordance with the previous literature, this study examined these aspects, including also mothers’ use of social media to stay informed about nutrition as an innovative element. The main goal was to validate the Italian version of the PSEPAD scale (Parental Self-Efficacy for Promoting Healthy Physical Activity and Dietary Behaviors in Children), which is a valid and reliable tool for assessing parental self-efficacy in encouraging healthy lifestyles in children, through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The sample was composed of 217 mothers. Results were interpreted through groups comparisons (chi-square, ANOVA, and t-test). The findings confirmed the central role of mothers in managing children’s diets and using strategies against picky eating behaviors. The study also highlighted the growing use of social media among mothers, especially younger ones, as a source of nutritional information, meal planning, and peer support, despite a generally low level of satisfaction with the content available on pediatric nutrition. Finally, the results showed a positive link between maternal self-efficacy and healthier child behaviors: mothers with higher self-esteem and confidence were more effective in promoting healthy habits. These findings underscore the importance of targeted interventions to strengthen maternal self-efficacy and the development of digital tools to support healthy family lifestyles. Full article

This paper presents Greenopoli, an innovative framework for sustainability and waste management education that has engaged over 600 schools and 90,000 students since 2014. Greenopoli is founded on the idea that children and youth can grasp environmental issues as well as adults and act as agents of change within their families and communities. The Greenopoli approach combines scientific accuracy with playful, creative pedagogy to simplify complex topics and stimulate peer-to-peer learning. It includes storytelling, games, field visits, and “green raps” (original environmental songs co-created with students). The framework is adaptive, with content and activities tailored to education stages from kindergarten through university. Educators adopt the role of moderators or facilitators, encouraging students to discuss and discover concepts collaboratively. Greenopoli’s participatory method has been implemented across all age groups, yielding enthusiastic engagement and tangible outcomes in waste sorting and recycling behaviors. The program’s reach has extended beyond schools through collaborations with national recycling consortia, NGOs, municipalities, and media (TV programs, social media, TEDx talks). Numerous awards and recognitions (2017–2025) have highlighted its impact. A comparative analysis shows that Greenopoli’s use of peer-led learning, gamification, and creative communication aligns with global best practices while offering a unique blend of tools. Greenopoli is a novel best-practice model in environmental education, bridging theory and practice and contributing to the goals of Education for Sustainable Development and a circular economy. It demonstrates the effectiveness of engaging youth as change-makers through interactive and creative learning, and it can inspire similar initiatives globally. Full article

The long-standing separation of agro-pastoral relations has adversely affected the agricultural economy and ecology, hindering sustainable agricultural development. The process of reconstructing agro-pastoral relations involves moving from separation to reintegration. To further verify the scientific validity of reconstructing agro-pastoral relations to improve economic and ecological benefits and enhance the capacity for sustainable agricultural development in the major corn-producing areas of Northeast China, this study used survey data from 521 sample farmers in Jilin Province, China, collected during the agricultural production cycle from 2020 to 2022. Using an endogenous switching regression (ESR) model and a counterfactual scenario, the integrated crop–livestock family farm (ICFF) model was shown to have a comparative advantage in improving economic and ecological benefits. The ICFF model can serve as a foundation for reconstructing agro-pastoral relations, thereby enhancing sustainable agricultural development capacity. Heterogeneity analysis indicates that larger-scale cultivated land, intensive cultivated land management, and higher education have a more significant impact on farmers’ choice of the ICFF model. To promote the restructuring of agro-pastoral relations through the ICFF model, farmers should be encouraged and supported to standardize the transfer of farmland, engage in livestock farming according to the principle of land-based livestock management, implement large-scale and intensive management, improve agricultural production technologies and improved varieties, strengthen publicity on the positive role of integrated crop-livestock management, and improve the financial support system.

Violence is an emerging social determinant of health in Latin America; however, empirical evidence from Peru remains limited. This study examined the association between crime rates and the prevalence of obesity and high blood pressure in Peru from 2019 to 2023. Using a repeated cross-sectional design with department–year aggregates, we analyzed nationally representative data from the Demographic and Family Health Survey, adjusting for sociodemographic, mental health, and geographic factors. Regional statistics on crime were incorporated into the analysis. The findings revealed a significant association between higher levels of crime and increased prevalence of self-reported high blood pressure and obesity. The association with obesity was particularly pronounced in border regions such as Tumbes, Madre de Dios, and Callao, where criminal activity is more prevalent. The findings indicate that prolonged exposure to violence may negatively impact biological stress responses, limit physical activity, and encourage the emergence of detrimental behaviors, consequently increasing the cardiometabolic risk burden in affected populations.

The role of international financial resource inflows, foreign direct investment (FDI), development foreign assistance (DFA), and personal remittance earnings (PRE) in decisive advancement toward environmental sustainability (SDG13) and economic development is increasingly recognized. However, depending on the situation, their effects on environmental outcomes vary in degree and direction, and are still subject to debate. This research examines how the three main international financial resources impact environmental sustainability, which is measured by the bio-capacity index, with a specific focus on the moderating role of corruption. The system panel generalized method of moments with balanced panel data (2001–2023) was used to attain the objectives of this study. This study focused on 28 developing Organization of Islamic Cooperation member countries because of their significant reliance on these financial inflows, regional/economic variety, and diverse levels of governance, which offer a crucial setting for evaluating the corruption moderation hypothesis. The findings reveal a comprehensive scenario of SDG synergies and trade-offs. In the base model, FDI directly improves the situation, whereas DFA and PRE are initially negligible. When considering internal economic factors, FDI and PRE greatly advance sustainability, whereas domestic financial measures such as domestic credit and fixed capital formation show adverse effects, underscoring a tension between environmental objectives and national financial systems. Importantly, the moderation analysis shows that while the advantages of FDI and PRE continue to be robust, corruption severely reduces the efficacy of DFA. To assure environmental effectiveness, these findings call for distinct policies that encourage green FDI, leverage remittances for green investments at the family level, and above all, fasten development assistance to strict governance changes.

Disabled people commonly report experiencing predetermined perceptions and assumptions of disability that form barriers towards understanding and treating disabled people equally. This process is known as ableism; a specific type of ableism called benevolent ableism intends to help and solicit assistance towards disabled people, but instead dismisses their capacity to advocate for their own needs, resulting in help that is deemed overly enforced, assumptive, and unwanted. A focus group and one informal interview were conducted to investigate the views and experiences of people living with cerebral palsy (CP), highlighting how benevolent ableism operates in their own lives, with additional forms of ableism also explored. Thematic analysis (TA) was applied to the data, resulting in three broad themes: benevolent ableism, strategies to improve and reduce ableism, and othering. The findings revealed that benevolent ableism was present when help was assumed, overly requested despite rejections of help, and belittling in nature; positive forms of assistance allowed the person with CP to instigate help and was accommodating; other forms of ableism were encountered, such as invasive staring, being treated like a child, charitable praise, being ignored within the medical setting, and lowered perceptions of capabilities. In order to diminish these difficult experiences and encourage practices, behaviours, and ideologies that promote less prejudice, participants mentioned education and improved interaction as being important aspects. Furthermore, this research poses wider implications for family members, teachers, medical professionals, and the general public to learn appropriate approaches toward disabled people and gain a better understanding of disability.

The history of women’s education in Portugal predates the implementation of an official system, which was only consistently addressed after 1836 with Passos Manuel’s reform of primary instruction. Long before that, particularly from the Early Modern period onwards, women religious played a key role in providing education. Convents and Third Order houses—alongside families, charities, and religion-inspired foundations—offered instruction considered appropriate to women’s gender and social status. The Council of Trent (1545–1563) extended strict enclosure to all female convents, leading to the “monasticisation” of education—an arrangement that neither promoted the visibility of female learners nor encouraged the development of the pedagogical models that shaped their instruction. The later emergence of teaching orders, despite their adherence to enclosure, began to challenge the traditional monastic model. Drawing on largely unpublished or scarcely explored archival sources, this article seeks to shed light on the historical reasons behind the prominent and precedent-setting role of monasticism in the field of female education, and to address the enduring invisibility that still shrouds the cloistered world.

Efficient oxygen transport and accurate anemia diagnostics remain significant medical challenges, as current therapies suffer from stability limitations, immunogenic risks, and inadequate sensitivity. Cucurbiturils (CB[n]), a family of pumpkin-shaped supramolecular macrocycles, present promising solutions due to their rigid architecture, hydrophobic cavities, and strong host–guest binding properties. Functional derivatives such as perhydroxy-cucurbit[5]uril can reversibly bind dioxygen under physiological conditions, highlighting their potential as synthetic hemoglobin substitutes. Additionally, cucurbituril-based probes for Fe³⁺ and folate enable sensitive and selective detection of iron- and folate-deficiency anemia. Biocompatibility assessments in vitro and in vivo indicate low systemic toxicity and acceptable hemocompatibility for homologues such as CB[6], CB[7], and CB[8], though apoptosis, myotoxicity, or cardiotoxicity may occur at elevated concentrations. These data emphasize the need for thorough toxicological evaluation but also demonstrate that cucurbiturils provide a versatile platform for oxygen transport, diagnostic applications, and drug-delivery strategies in anemia management. While their translation to clinical practice is still at an early stage, the structural tunability, stability, and encouraging safety profile of CB[n] macrocycles offer a strong basis for continued biomedical development.

Background/Objectives: Despite extensive research on the outcomes faced by parents in contexts of political violence, as well as the protective factors that enhance their well-being, the experiences of single parents by choice (SPCs) in such circumstances have largely been neglected. This study sought to address this gap by examining the experiences of SPCs during the current phase of the Israel–Hamas war that began on 7 October 2023. Method: This qualitative study used a context-informed approach. Semi-structured interviews were conducted with 11 Israeli SPCs (5 fathers and 6 mothers), including 2 displaced due to the destruction of their homes. All participants were secular Jews, predominantly middle- to upper-middle-class, aged 40–58, and had at least one child aged 15 months to 17 years. A thematic analysis method was utilized. Results: Two overarching themes emerged from the interviews, shaping participants’ wartime experiences: (1) the intensified challenges associated with parenting alone in the context of armed conflict and (2) the factors that mediated the impact of these challenges. Three key challenges identified by participants included: (1) persistent perceptions of danger and threat to life; (2) heightened financial insecurity; and (3) significant disruptions to daily routines. Three systemic-level protective factors were identified as instrumental in mitigating these challenges: (1) engagement in joint familial activities; (2) the presence of a supportive work environment; and (3) social and political engagement. These factors appeared to foster resilience and enhance participants’ psychological coping capacities amidst ongoing conflict. Conclusions: By highlighting the distinct stressors faced by SPCs in wartime and the factors mediating their impact on well-being, our findings extend the Stress Process Model to conflict settings, enhancing understanding of how single parenting is contextually shaped during major community crises. The findings may encourage clinicians and social workers to adopt a more nuanced approach when working with parents in conflict zones, enabling them to tailor interventions to the specific needs of different family structures. For SPCs, such interventions may include tele-counseling to provide psychosocial support and guidance for parents in supporting their children, without the need for childcare or travel, as well as advocacy for workplace policies that reduce financial and emotional vulnerabilities.
