Municipal solid waste challenges (MSW) and concerns about fossil fuel dependence motivate efforts to recover energy from waste, including refuse-derived fuel (RDF). Techno-economic assessment (TEA) evaluates the feasibility of systems by quantifying investment performance. However, most RDF-TEA studies typically rely on isolated sensitivity analyses. That provides limited insight into interaction effects in emerging markets. This study maps the multivariable feasibility of RDF production from MSW in Ghana under realistic economic conditions. Using a pilot-calibrated case study, the assessment integrates discounted cash flow analysis with response surface methodology–design of experiment (RSM-DoE). A central composite design evaluates interaction effects among operational and economic variables for a system capacity of 2875 tonnes RDF/year. The results indicate economic viability with a net present value (NPV) of USD 892,556.44, a payback period (PBP) of 6.61 years and a levelised production cost (LPC) of USD 18.96/tonne. The RSM models show high explanatory power (R², R²adj, R²pred > 90%). Sensitivity results demonstrate that support mechanisms can significantly reduce LPC and PBP while preserving investment viability. The study quantifies the feasibility thresholds and the support instruments within the RDF design levers. It further provides a transferable framework for assessing deployment and upscaling in emerging markets. The findings highlight the need for structured pricing mechanisms and regulatory support for the long-term sustainability of RDF as an AF. Full article

Cross-border e-commerce, as an emerging trade format, offers new chances for optimizing industrial chains’ layout, enhancing economic resilience, and attaining high-quality development at the city level. In this context, treating the execution of the cross-border e-commerce comprehensive pilot zone (CBEC) as a quasi-natural experiment, this study subtly attests to how the CBEC affects urban entrepreneurship by using a difference-in-differences (DID) technique. The results exhibit that the CBEC greatly promotes urban entrepreneurship, which is supported by some robustness tests, including instrumental variable testing and placebo testing. Heterogeneity analysis reveals that in cities with more developed economies, stronger digitalization, richer cultures, sounder law rules, and better business environments, the benefit for the CBEC on entrepreneurship is more significant. Mechanism testing argues that the CBEC promotes urban entrepreneurship through talent aggregation and industrial upgrading. Precisely, the more concentrated high-quality talents are and the more advanced the industrial structure is, the higher the urban entrepreneurship. More importantly, the CBEC exhibits a spatial spillover effect on entrepreneurship, promoting local entrepreneurship while stimulating the motivation to imitate and learn in neighboring areas, thereby driving their entrepreneurship. The findings offer a viable decision-making guide for building a unified factor market and achieving regional coordinated development. Full article

Green technologies are strongly present in the energy mixes of countries around the world. In addition to the need to reduce the extraction of non-renewable raw materials and the harmful environmental impact associated with energy production, the trend towards renewable energy development should also be linked to the need to minimize energy poverty stemming from high electricity prices and the need to increase the energy efficiency of existing solutions. These issues formed the basis for the study’s objective, which was to examine the regulatory framework for the development of Poland’s energy system, with particular emphasis on sustainable development. A particularly important aspect of the study was the exploration of the market for green technologies introduced into the energy system in Poland, with a primary focus on solutions dedicated to small, individual consumers (households). The cognitive value of the study and its original character is created by the cognitive aspect in terms of the interests and consumer preferences of households in this area, motivated by economic considerations related to the energy efficiency aspect of RES solutions. In this regard, there is a relatively limited number of current studies conducted for the reference country (Poland), justifying the choice of the research topic and theme. For the purposes of the study, a literature review, as well as legal standards and industry reports, was conducted. A practical study was conducted based on the results of surveys conducted by selected companies involved in the sale and installation of heating solutions. Detailed research was supported by statistical instruments using PQstat software version 1.8.4.164. Key findings confirm significant household interest in green electricity production technologies, which enable improved energy efficiency of home energy installations. Importantly, the potential for lower electricity bills, which can be attributed to low system maintenance costs and the ability to manage consumption, is a factor in choosing renewable energy solutions. Current interest in renewable energy solutions focuses on heat pumps, photovoltaics, and energy storage. Renewable energy users are interested in integrating renewable energy technology solutions into energy production and management to optimize energy consumption costs and increase household energy independence.

As a pivotal instrument for fostering sustainable development and climate goals, low-carbon city pilot policies (LCCPs) motivate firms to increase environmental investments, thereby harmonizing economic growth with emission reduction. This study employs a difference-in-differences (DID) design to empirically investigate the effects and underlying mechanisms of LCCPs on firms’ environmental investment in China. The results demonstrate that LCCPs lead to a significant increase in corporate environmental investment of approximately 36.5% (with a core coefficient of 0.365, significant at the 1% level) when compared to non-pilot cities. This impact primarily occurs through five channels: technology transformation, environmental regulation compliance, financial support, talent attraction, and policy alignment. Heterogeneity tests further reveal that the effect is stronger for enterprises in the eastern and western regions, non-entrepreneurial boards and non-financial entities, larger firms, and those facing financing constraints and operating in low-industry competitive environments. This study offers evidence for the importance of LCCPs in driving corporate environmental investments, providing valuable policy implications for enhancing regulatory frameworks and fostering green innovation to support carbon neutrality and sustainable economic transitions.

The purpose of this study is to explore social work students’ knowledge, attitudes, and support for reparations for African American descendants of chattel slavery and persistent structural discrimination. A 44-item self-administered online survey instrument was used to gather data. A total of 91 social work students across the United States responded to the survey. The findings demonstrated that there is a knowledge deficit about reparations. An overwhelming majority of students reported that they had never taken a college course that included content on reparations. To address this void, nearly 95% of the respondents indicated that they would like to learn more about H.R.40, a legislative bill that seeks to establish a commission to study proposals for reparations in the United States. Reparations align with the mission, values, and competencies of social work; therefore, students’ desire to learn more about this topic should serve as a motivator for U.S. social work educators to include this content in graduate and undergraduate courses.

(1) Background: The present study aimed to develop and validate the Scale for the Identification of Emotional Resilience in Children (SIER-C), a psychometric instrument designed to assess key dimensions of emotional intelligence and resilience among children aged 6 to 12 years. (2) Methods: The sample comprised 367 participants (52.3% male, 47.7% female) drawn from both urban and rural educational settings across Romania, selected through stratified random sampling to ensure demographic representativeness. The SIER-C consists of 30 items distributed across six subscales: Recognition and Understanding of Emotions (RUE), Emotion Regulation (ER), Empathy (E), Attitude Toward Failure (ATF), Coping Strategies (CS), and Perseverance and Self-Motivation (PSM), with items rated on a 5-point Likert scale. An Exploratory Factor Analysis (EFA) was initially conducted to examine the underlying factor structure, followed by Confirmatory Factor Analysis (CFA) to validate the model. (3) Results: The EFA suggested a six-factor structure consistent with the intended subscales, which was subsequently confirmed by CFA, demonstrating satisfactory model fit indices and confirming the scale’s construct validity. Internal consistency indices and composite reliability coefficients further indicated robust psychometric properties across subscales. (4) Conclusions: The findings underscore the relevance of SIER-C as a reliable and valid tool for identifying nuanced profiles of emotional intelligence and resilience in children. These profiles provide valuable insights for early detection of emotional and adaptive vulnerabilities and for the design of targeted interventions within educational and clinical frameworks. Future research should explore the longitudinal stability of these constructs and examine the integration of SIER-C within social–emotional learning programs to support the development of emotional competencies from a preventive and developmental perspective.

Background: Procedural pain and anxiety are common phenomena among children hospitalized in pediatric wards; however, they are often under-recognized. These experiences frequently accompany patients during various diagnostic and therapeutic procedures. Assessing pain is particularly challenging in pediatric care, as children may have difficulty clearly expressing their pain experiences, which can result in the underestimation of their symptoms. Accurate assessment using an appropriately selected scale should be regarded as an essential component of high-quality healthcare. Methods: This narrative review summarizes standardized tools for assessing procedural pain and anxiety in pediatric patients, focusing on instruments adapted to different ages and cognitive abilities and on their applicability in everyday clinical practice. Results: Numerous standardized scales are available, ranging from behavioral to numerical instruments tailored to specific developmental stages. Despite this, the implementation of these tools in routine care remains inconsistent, largely due to organizational, educational, and communication barriers among healthcare professionals. Conclusions: Medical staff must not only receive adequate training but also exhibit the motivation and readiness to utilize available pain assessment methods. Education and increased awareness among staff regarding pain and procedural anxiety are crucial for improving patient comfort and safety. Full article

Teaching the host country’s language is not only a form of linguistic education but also a means of integrating foreign citizens into society, thereby promoting sustainable cultural change and social inclusion. This article, based on an ecolinguistic approach combined with Gardner’s motivation theory, examines the opportunities for social inclusion of international students at VILNIUS TECH (Vilnius Gediminas Technical University, Lithuania) through learning Lithuanian as the host country’s language. From the ecolinguistic perspective—which highlights the interconnections between language, identity, and the learning environment, and which shapes sustainable human relationships and social behavior—the study analyses the instrumental and integrative motivation of international students learning Lithuanian. A quantitative survey of 212 bachelor-level students was conducted, and responses were analyzed using descriptive statistics and motivational categories. The findings reveal that integrative motivation (cultural interest, respect for the host country, and desire for belonging) is significantly stronger than instrumental motivation (career and pragmatic value). However, despite strong positive attitudes toward the language, students experience limited social inclusion and few opportunities to use Lithuanian outside the classroom. The interplay between motivation types and environmental conditions shows how language learning contributes to social inclusion, the preservation of the host country’s linguistic prestige, and broader cultural sustainability.

Amid growing “nature deficit” associated with urbanization and indoor living, flowering plants are increasingly used to support psychological restoration. Yet evidence on how floral color and structural morphology jointly shape restorative outcomes remains limited. This study employed a within-subjects, repeated-measures design, utilizing physiological instruments and psychological questionnaires to investigate the physiological and psychological restorative benefits of Hydrangea macrophylla and to quantify the differences in restorative effects across five colors (blue, pink, white, mauve, red), two inflorescence types (mophead, lacecap), and two petal structures (single, double). Twenty-eight healthy young adults viewed 15 live hydrangea stimuli under controlled laboratory conditions. Multimodal outcomes combined objective measures—eye-tracking and single-channel EEG—with subjective measures (SD; POMS). Hydrangea exposure significantly reduced negative mood, and color and structure exerted distinct and interactive effects on visual attention and arousal. Red and mauve elicited larger pupil diameters than white and pink, while lacecap inflorescences were associated with lower cognitive load and improved attentional recovery relative to mophead. Double-petaled forms showed greater attentional dispersion than single-petaled forms. Interactions indicated that morphology modulated color effects. The mauve lacecap double-flowered cultivar (M02) showed the strongest observed restorative potential within this sample. These findings highlight the importance of integrating color and structural cues when selecting flowering plants for restorative environments and horticultural therapy, and they motivate field-based replications with broader samples and higher-density physiology.

Artificial Intelligence in Education is expanding rapidly, yet the adaptation of chatbots to specific reading-comprehension levels remains underexplored. This mixed-methods study presents Lectobot, a conversational agent designed to provide personalized scaffolding across three levels of reading comprehension (literal, inferential, and critical). First, we conducted a diagnostic assessment with first-year undergraduates (N = 58) using validated instruments: COMPLECsec (reading comprehension), EMA (Academic Motivation Scale), and MARSI (Metacognitive Strategies). Non-parametric analyses (Kolmogorov–Smirnov; Mann–Whitney U with Benjamini–Hochberg adjustment) indicated wide heterogeneity in comprehension (median global accuracy ≈ 55%) and a predominance of extrinsic motivation, with selective use of problem-solving strategies. These findings informed design rules for Lectobot (text selection, adaptive task difficulty, and strategy prompts). In a five-week implementation with a focus group (n = 8), semi-structured interviews were transcribed and coded in MAXQDA, guided by the Technology Acceptance Model (perceived usefulness and ease of use). Students perceived Lectobot as useful for text understanding and synthesis and moderately easy to use; reported difficulties were mainly technical (access and session continuity), leading to actionable design improvements. We discuss ethical and practical implications for personalized scaffolding in higher education and outline avenues for larger-scale evaluations and broader grade levels. Full article

High-quality, interoperable biodiversity information is a prerequisite for effective conservation policy, compliance with European Union (EU) reporting obligations, and efficient environmental decision-making. Greece’s LIFE EL-BIOS (LIFE20 GIE/GR/001317) developed the first National Biodiversity Information System, aiming to aggregate, standardise, and disseminate spatial and non-spatial data for species, habitats, pressures, and trends. This paper provides an economic valuation of this information system as a public, non-market good. We designed a two-stage stated-preference study: (i) a short pre-survey to calibrate initial bids and (ii) the main survey employing double-bounded dichotomous choice (DBDC) contingent valuation with a spike-logit specification. The payment vehicle was a hypothetical monthly subscription in a post-LIFE scenario. The instrument measured time savings (hours), perceived reliability (Likert 1–5), and key demographics/roles. A total of 167 valid responses were collected in September 2025. Participants reported an average of 5.2 h saved per use (median 4; max 14). Among those expressing willingness to pay (WTP), 77% rated EL-BIOS reliability as “High/Very high”. Econometric results indicate time savings as the strongest positive determinant of WTP; perceived reliability is positive and marginally significant; years of experience are negatively associated with acceptance; and cost has a strong negative effect. Mean WTP is estimated at €6.7 per month (median €3.5). Notably, 64% of those unwilling to pay declared protest motives (data should remain public and free). Accordingly, non-payment is decomposed into true zero WTP versus protest-based refusal, i.e., refusal to pay despite acknowledging value. This high protest share reflects principled opposition to paying for public biodiversity data rather than low perceived value of the system. The EL-BIOS database generates measurable productivity gains and social value both through positive WTP and principled protest responses supporting open public data. These findings inform policy on sustainable financing, governance, and long-term operation of national biodiversity information systems. Full article

This study examines the relationship between electronic device use and psychological dimensions of procrastination in university students. The main objectives were to identify screen usage habits, explore their association with key psychological factors, and determine whether these factors predict perceived procrastination. An ad hoc instrument and descriptive, correlational, and regression techniques were used for data analysis of a sample of 924 Spanish university students. From this sample, a target subsample of 386 students who reported high levels of procrastination was selected to analyse screen-use patterns and their links with procrastination dimensions. In contrast, the full sample was used to estimate the predictive regression models. Results showed high screen use among students, with 20% potentially at risk for problematic use. High screen use correlated with lower self-regulation, self-efficacy, and self-esteem, and higher anxiety. Conversely, higher self-regulation and self-efficacy were linked to more motivation, better self-esteem, and less anxiety. Regression results indicated that screen time, self-regulation, and self-efficacy significantly predict procrastination levels. These findings suggest that psychological factors play a key role in how screen use relates to procrastination. Full article

Intergovernmental transfers play a crucial role in shaping the fiscal position of local governments, especially in countries where municipalities, such as those in Poland, exhibit a high dependence on central funding. Recent reforms and the increasing reliance on discretionary revenues transferred from the central budget have motivated a closer examination of how these instruments influence local fiscal sustainability. This article analyses how different types of transfers—general subsidies and targeted grants—affect the fiscal sustainability of Polish municipalities across several dimensions, including autonomy, solvency, efficiency and economic resilience. Using panel data, five sets of models test the crowding-out effect, developmental impact, pro-cyclicality, fiscal discipline, and fiscal replacement mechanisms. Results show that general subsidies crowd out local tax revenues, particularly in less developed municipalities, while targeted grants strengthen the tax base in rural areas. Transfers have mixed effects: targeted grants strongly stimulate investment and support local development but tend to increase debt; general subsidies weaken local tax capacity and reduce fiscal autonomy, although they improve short-term fiscal discipline. In municipalities with limited fiscal independence, transfers act as short-term compensatory tools, fostering dependence on state aid rather than self-reliance. A macroeconomic crowding-out effect also appears, as higher transfers reduce private sector resources. Regarding fiscal discipline, equalization and compensatory subsidies decrease debt levels, whereas targeted grants can raise debt in urban municipalities with co-financing obligations. General subsidies show fiscal replacement effects, substituting local revenue sources. The findings provide insights for designing transfer systems that balance financial support with incentives for local autonomy and sustainable development. Full article

Digital transformation is reshaping work and management, yet evidence on how technological innovation interacts with workplace well-being, leadership, organizational culture, and human-centered management remains fragmented. This study aims to integrate these strands of research by examining how innovation and digitalization affect employee well-being and motivation in organizational contexts. A systematic literature review was conducted in accordance with PRISMA 2020 guidelines, with a protocol registered on INPLASY. The search was performed in the Scopus database and identified 287 eligible studies (1989–February 2025). Bibliometric keyword co-occurrence analysis using VOSviewer (1.6.20), combined with qualitative content and thematic analysis, led to five clusters: (1) innovation and well-being; (2) leadership pathways to workplace well-being; (3) work motivation and job satisfaction; (4) human-centered management in technological progress; and (5) organizational culture. The results show that organizations reconciling innovation and people’s well-being tend to adopt leadership styles and cultures grounded in ethical values, inclusion, psychological safety, and balanced work demands and resources, operationalized through human-centered management practices. These findings offer an integrated framework that goes beyond an instrumental view of technology and provide guidance for leaders, HR professionals, and policymakers designing digital transformation strategies that foster responsible innovation and promote sustainable, health-promoting work environments.

This study explores the impact of integrating formal and non-formal learning in secondary school education through a mixed-methods experimental design. A total of 120 students (aged 14–16) from two secondary schools were randomly assigned to an experimental group (n = 60) and a control group (n = 60). The experimental group participated in a twelve-week interdisciplinary programme that combined traditional curricular subjects with non-formal educational practices such as sports, theatre, art, and community engagement, supported by digital learning platforms. Quantitative data were collected through validated instruments, while qualitative data were gathered through observations, focus groups, and semi-structured interviews with students, teachers, and parents. Statistical analyses (t-tests and ANOVA) revealed significant improvements in intrinsic motivation, psychological well-being, and sense of belonging among students in the experimental group compared to the control group. Thematic analysis of qualitative data confirmed these findings, highlighting increased collaboration, engagement, and inclusion. The results indicate that integrating formal and non-formal education fosters holistic learning, strengthens community ties, and promotes emotional and cognitive development. These findings provide empirical support for policies and pedagogical practices aimed at developing flexible, participatory, and sustainable educational models. Full article
