Work engagement is pivotal for service quality and the long-term viability of platform businesses, yet its micro-level drivers remain insufficiently understood in algorithmically managed gig work. Drawing on self-regulation, social exchange, organizational justice, and algorithmic governance perspectives, this study develops an integrative framework linking workers’ self-management, perceived organizational support, organizational justice, and perceived algorithmic control to work engagement. We surveyed 292 platform-based gig workers in China using an online questionnaire. Hierarchical regressions and robustness checks using structural equation models show that all four antecedents are positively associated with engagement; when considered jointly, perceived algorithmic control, organizational support, and organizational justice remain significant, whereas the incremental association of self-management becomes weaker. Facet-level analyses further indicate that self-improvement is the key self-management mechanism; supervisor, coworker, and climate support all contribute; distributive, procedural, and interactional justice are all positively associated; and the algorithmic process and outcome control matter more than perceived task discretion. The findings highlight actionable levers for social sustainability and decent work in the platform economy, including strengthening developmental opportunities, institutionalizing fair and contestable governance, and improving the transparency and predictability of algorithmic decisions.

This study investigates how pandemic-induced digitalisation, understood as the transition to remote work combined with the enforced use of digital tools and the reconfiguration of tasks and digital skills at the job level, has affected job security and job quality in Portugal. In 2022, a nationwide survey was administered to employees in companies registered in the country, yielding 2001 valid responses through a stratified random sampling strategy that ensured representation across different firm sizes. Structural equation modelling (PLS-SEM) was used to examine the relationships between digitalisation (independent construct) and perceived job quality and job security (dependent constructs), while controlling for demographic, organisational, and work-regime characteristics. Digitalisation had a significant positive effect on perceived job quality but no systematic effect on perceived job security. The results also revealed more positive perceptions of job security among women, employees in smaller firms, and those working on-site, whereas directors and workers in the Lisbon Metropolitan Area reported greater negative effects. These findings underscore the importance of contextual factors in shaping how workers experience digitalisation and provide evidence to inform public policies aimed at promoting job security and job quality in a post-COVID-19 labour market.

We announce the U.S. Geological Survey (USGS) Rotating X-ray Computed Tomography (RXCT) Coral-Core Archive, a digital resource derived from ~360 coral reef cores curated at the USGS Pacific and St. Petersburg Coastal and Marine Science Centers. The archive delivers calibrated 3-dimensional image volumes that enable reproducible values of skeletal density, linear extension, and calcification from decadal- to centennial-scale records of coral growth and bioerosion. Cross-study comparability within the archive is supported by a unified RXCT workflow that minimizes imaging artifacts. This includes rejecting image-intensity–density calibrations with r² < 0.95, back-calculating standard densities to verify a ±10% target precision, and confirming that band-averaged density values fall within published species- and site-specific ranges. Our release of data under FAIR (Findable, Accessible, Interoperable, Reusable) principles is important given global coral reef decline and the rarity of physical coral archives. Calibrated imagery and scan metadata are distributed through CoralCache/CoralCT for analysis (DOI: 10.5194/essd-2025-598), while core locations and collection metadata are published through the USGS Geologic Core and Sample Database (DOI: 10.5066/F7319TR3) with links to CT imagery in a USGS ScienceBase repository (DOI: 10.5066/P139Y9H4). This archive provides a powerful dataset for evaluating environmental controls on coral growth, establishing restoration baselines, and improving coastal hazard assessments in the face of global coral reef declines.

Inflation expectations play a central role in monetary policy effectiveness, yet relatively little is known about how individual behavioral traits shape expectation formation. This study examines whether time discounting and hyperbolic discounting, key dimensions of intertemporal preferences, are systematically associated with household inflation expectations. Using large-scale survey data from Japan that elicit both time preference measures and qualitative inflation expectations, we analyze expectations over one-, three-, and five-year horizons. The empirical analysis employs ordered probit models that fit well with the categorical nature of survey-based inflation expectations and controls for a rich set of demographic, socioeconomic, and behavioral characteristics, including financial literacy and risk preferences. The results reveal clear horizon-dependent patterns. Hyperbolic discounting is positively associated with short-term inflation expectations, suggesting that present-biased individuals place greater weight on recent inflation developments. In contrast, higher time discount rates are associated with higher inflation expectations at medium and longer horizons, indicating that impatience is more relevant for beliefs about distant future prices. These findings provide novel evidence on the behavioral micro-foundations of inflation expectation formation and highlight the importance of heterogeneity in time preferences. From a policy perspective, the results suggest that one-size-fits-all communication strategies may be insufficient and that effective expectation management may require tailoring messages to account for differences in individuals’ time orientation across forecast horizons.

The roof aquifer of the Jurassic coal seam is the primary source of water inrush in the Nalinhe Mining Area. It poses a severe threat to safe mining operations. Accurate prediction of its water richness is crucial for production safety. This study focuses on the Nalinhe No. 2 Coal Mine. Seven key controlling factors were selected as evaluation indicators, including aquifer thickness, burial depth, core recovery rate, the thickness ratio of brittle to plastic rock, fault scale density, fault fractal dimension, and the density of fault endpoints and intersections. A hybrid weighting strategy was applied in this study. This strategy integrates the Analytic Hierarchy Process (AHP) and the Entropy Weight Method (EWM) to assign scientific weights to the evaluation indices. A water richness evaluation model was subsequently developed based on matter-element extension theory. The model calculates the comprehensive correlation degree for each grid node and determines the corresponding water richness level. Zoning results were validated with unit inflow data from pumping test boreholes, mine inflow observations, and ground transient electromagnetic survey findings. The predicted water richness zones closely matched the measured hydrogeological data. These results demonstrate the scientific rigor and reliability of the matter-element extension model. The proposed model provides a novel approach for assessing water richness in coal seam roof aquifers. Full article

The diamondback moth, Plutella xylostella (L.), is a significant pest of brassica crops that is found across the globe. Due to the development of insecticide resistance, control tactics have shifted focus towards integrating pest management techniques such as biological control. Diadegma insulare (C.), Oomyzus sokolowskii (K.), and Microplites plutellae (M.) are parasitoids of P. xylostella found in the Eastern United States. From 2022 to 2025, we surveyed P. xylostella larvae and pupae in locations across Virginia to assess the current rates of parasitism in brassica fields. Specimens were brought to the laboratory and reared to assess parasitoid emergence rates. Only D. insulare specimens were found during the study. Adult P. xylostella, larvae and pupae, adult D. insulare, D. insulare pupae, unknown parasitoids, and unknown deaths were recorded and used to calculate the rates of parasitism at each location. We concluded that the parasitism rate varied by location and year, which was expected due to regional conditions and seasonality. Rates averaged between 30.1 and 65% by year, with the lowest individual rate being 15% in 2025 and the highest at 100% in 2022. This suggests that D. insulare is actively present in Virginia and could be a successful biological control agent when paired with other integrated pest management techniques to reduce P. xylostella populations.

Climate change exerts an increasing impact on the health and resilience of honey bees through a combination of rising temperatures, altered precipitation patterns, and intensified parasitic and infectious pressure. The present study aims to analyze climatic conditions in Bulgaria for the period 2021–2024 and to evaluate the results of a national survey conducted among beekeepers, focusing on winter colony losses during the 2023/2024 season and the feeding strategies applied. The survey was carried out in 2024 among 70 beekeepers from 20 administrative regions of the country, managing a total of 8935 bee colonies. The data were analyzed using descriptive statistics and stratified by region. The reported average winter mortality was 2.22% (198 colonies), with pronounced territorial variability. The most frequently indicated self-reported probable cause of losses was bee diseases, with varroosis identified as the dominant factor. Analysis of management practices revealed widespread application of combined feeding schemes based on plant-derived supplementary feeds, primarily administered in spring (March–April) and late summer (August–September). The obtained results differ from published national data for 2024, according to which total colony losses reached 16.3%, while losses associated with mortality or severe demographic collapse accounted for 11.6%. Despite the limitations inherent to the survey-based approach and self-reported data, the results suggest that integrated management combining parasite control with targeted nutritional support through the use of Bulgarian herbal supplementary feeds may coincide with the winter survival patterns reported within the surveyed sample.

Grounded in attachment theory, the present study aimed to examine the predictive effects of deceased-specific attachment styles (anxious and avoidant) on grief and to test the mediating roles of two dimensions of unfinished business, namely unfulfilled wishes and unresolved conflicts. Using a two-wave longitudinal design, we conducted a 3-month follow-up survey (T1: October 2024; T2: January 2025) among Chinese adults who experienced bereavement within the past five years. Participants completed the Experiences in Close Relationships—Relationship Structures questionnaire at T1 and the Unfinished Business in Bereavement Scale and the International Prolonged Grief Disorder Scale at both T1 and T2. A total of 206 participants (Mage = 25.07 years; 51.94% women) completed both assessments. After controlling for T1 grief, demographic- and loss-related covariates, T1 deceased-specific attachment anxiety and attachment avoidance did not directly predict T2 grief. However, T1 deceased-specific attachment avoidance significantly negatively predicted T2 unfulfilled wishes, and both unfulfilled wishes and unresolved conflicts at T2 significantly positively predicted T2 grief. Furthermore, T2 unfulfilled wishes significantly mediated the relationship between T1 deceased-specific attachment avoidance and T2 grief. Thus, directly targeting unfinished business may serve as a more efficient and specific clinical strategy than broad attachment-focused interventions. Full article

With increasing worldwide attention to green and sustainable energy, thermal infrared remote sensing technology has gained significant popularity for detecting geothermal anomalies, as it can overcome the limitations of traditional ground surveys. This study explores the potential application of thermal infrared images in geothermal exploration within the Datong Basin. We mainly utilized Landsat-8 images to obtain the actual land surface temperature (LST), hydrothermal alteration, and linear structures of the Datong Basin. Radiative transfer equation algorithm (RTE), principal component analysis (PCA), and interactive interpretation method were applied in this study. The results show that LST retrieval through the RTE method accurately reveals geothermal anomalies in the Datong Basin. Five areas with distinct high-LST values were identified as geothermal anomaly zones based on field investigation, including Xiejiatun, Gushancun, Taipingpu, Shuitongsi, and Wenjiayao–Yuanjialiang. Effective estimation of hydrothermal alteration zones (dominated by clays, OH⁻/H₂O, and carbonates) in the basin was achieved using the PCA method and band combinations. In total, 394 linear structures were obtained through interactive interpretation, including 45 concealed structures. All of these linear structures were associated with deep-seated faults. The basin’s primary controlling structures are the Yunmen Mountain piedmont fault (F1-1) and the northern margin of Xiong’er Mountain faults (F1-2 and F1-3), with F1-1 and F1-3 playing a key role in regional thermal regulation. The high-LST premium geothermal target zones of Shuitongsi and Gushancun were identified based on remote sensing interpretations and geothermal geological conditions. Furthermore, strong consistency was verified between the remote sensing predictions and four deep drilling temperature field measurements. This study confirms that remote sensing is an effective approach for geothermal potential identification, providing a scientific basis for future sustainable resource exploration in other regions.

Background: The efficacy of pharmacotherapy for attention-deficit/hyperactivity disorder (ADHD) has been confirmed in numerous controlled studies. However, in clinical practice, pharmacological treatment is heavily dependent upon the parents or guardians of patients. Parental attitudes are shaped not only by medical knowledge but also by parental beliefs about the use of pharmacotherapy and psychoactive substances, including ADHD pharmacotherapy. Parental beliefs about the safety and possible side effects of pharmacotherapy significantly influence their decision to accept or reject pharmacotherapy. This study aimed to explore parental beliefs and attitudes toward ADHD pharmacotherapy and their association with parental treatment acceptance and treatment-related decision-making. Methods: The cross-sectional online survey included 506 parents of children diagnosed with ADHD, recruited through closed social media groups. Parental treatment acceptance and decisions regarding initiation of pharmacotherapy were examined. Results: Parents of children with experience of pharmacotherapy more frequently considered pharmacotherapy safe (83.4% vs. 39.7%, p < 0.001) and expressed readiness to start treatment immediately (73.8% vs. 32.5%, p < 0.001). In this group, 72.6% of parents indicated that the benefits of pharmacotherapy outweigh potential risks. However, concerns about addiction were similar in both groups (49.4% vs. 45.3%, p = 0.400). In a gendered analysis, fathers were more likely than mothers to consider pharmacotherapy unnecessary for treating ADHD (35.3–22.4%; p = 0.002; V = 0.142) or disbelieve in ADHD treatment (25.7–15.1%; p = 0.005; V = 0.132). Furthermore, fathers were more likely than mothers to support limiting the use of pharmacotherapy for treating ADHD to those over 18 (41.3% vs. 26.5%; p < 0.001; V = 0.156), and to report parental opposition (28% vs. 8.1%; p < 0.001; V = 0.264), with a minimal to moderate effect size. Conclusions: Parental treatment acceptance decisions were associated with more favorable parental beliefs, although subjective concerns about addiction remained. Given the study’s cross-sectional and exploratory nature, causal interpretations should be avoided. Parental gender was associated with differences in beliefs and attitudes toward the use of pharmacotherapy for treating children diagnosed with ADHD, especially regarding necessity, consent and age-specificity. In our surveyed sample, fathers tended to be more restrictive or cautious than mothers. The findings also highlight the importance of psychoeducation and partnership-based communication between clinicians and families as key factors that may help support treatment acceptance-related decision-making in ADHD.

Decentralized Identity (DID) systems aim to restore user control over digital identities by minimizing reliance on centralized authorities. However, ensuring secure identity management in distributed environments remains a significant challenge. Biometric authentication offers a compelling solution by leveraging unique, non-transferable human traits to enhance security and usability compared to traditional methods such as passwords or tokens. Integrating biometrics into DID frameworks represents an important step toward privacy-preserving, user-centric identity verification aligned with the principles of decentralization. Despite growing interest in both biometrics and DIDs, their integration remains largely underexplored in the literature, with hardly any survey providing a systematic analysis of this convergence. This work addresses this gap by presenting a comprehensive review of biometric-enabled DID systems, examining their architectures, potential, and limitations. It emphasizes the role of multimodal biometrics in enhancing accuracy, inclusiveness, and resistance to spoofing, while highlighting key challenges related to data immutability, privacy preservation, interoperability, and regulatory compliance. Overall, this survey establishes a structured foundation for future research on secure, scalable, and privacy-preserving biometric-enabled decentralized identity frameworks. Full article

The poultry red mite Dermanyssus gallinae (PRM) is a hematophagous ectoparasite of major veterinary and public health concern, recognized as a potential vector of zoonotic pathogens. Despite recent advances in characterizing its microbiota, the temporal dynamics of the microbial community remain poorly understood. Here, we conducted a longitudinal metabarcoding survey of engorged PRM collected from a commercial cage-free laying hen farm over the laying hen’s productive cycle (30–105 weeks). High-throughput sequencing of the 16S rRNA V3–V4 region generated 412,078 sequences, identifying 186 bacterial species across all samples. Microbial richness peaked at 30 weeks (164 species), but sharply declined thereafter, with only 28, 55, and 43 species detected at 60, 90, and 105 weeks, respectively. Ordination (NMDS) and PERMANOVA analyses revealed significant temporal restructuring of microbial communities (R² = 0.76, p < 0.01), with distinct clustering across sampling points. A small subset of taxa persisted throughout time, including the genera Bartonella and Rickettsiella, while many species exhibited transient or stage-specific occurrence. Notably, zoonotic pathogens such as Staphylococcus aureus, Kocuria massiliensis, and Bartonella vinsonii were detected, suggesting that PRM may harbor microorganisms of potential medical and veterinary relevance. Overall, our findings demonstrate that PRM harbors a highly diverse but temporally dynamic microbiota, which progressively contracts into a community dominated by stable symbionts. These results highlight critical windows for microbial succession and reinforce the relevance of microbiome-based surveillance and integrated control strategies within a One Health framework.

The accelerated pace of urbanization has significant effects on the community composition, structure, regional distribution, and diversity characteristics of vegetation within urban river corridors. Spontaneous plants have strong environmental adaptability, high plasticity, and shorter life cycles; they also operate largely independently of human control. As a result, they are widely distributed throughout urban river corridors, and their ability to respond rapidly to heterogeneous habitats within these corridors makes them an ideal subject for studying the reciprocal mechanisms between rapid urbanization and riverine biodiversity. Based on a survey of 208 plots across six river corridors in Changchun, China, we found that the hydrological gradient was the strongest predictor of spontaneous herbaceous community distribution among the environmental factors examined. A total of 181 native herbaceous plant species, belonging to 55 families and 140 genera, were recorded. The Asteraceae, Poaceae, Fabaceae, Lamiaceae, and Polygonaceae families dominated. TWINSPAN classification divided the native herbaceous plant communities into 11 types, with the dominant species being predominantly low-growing perennial herbaceous plants. Canonical correspondence analysis (CCA) ordination confirmed this pattern, showing that the community distribution from aquatic to terrestrial habitats primarily aligned along the first CCA axis (defined by water depth and canopy cover), while the second axis reflected gradients in anthropogenic disturbance and slope. Thus, even in intensively managed urban rivers, natural hydrological processes remain pivotal in shaping riparian plant community composition and enhancing biodiversity. This study provides a scientific foundation for the conservation and sustainable utilization of plant resources in urban river corridors. Full article

Background: The translation of antimicrobial resistance (AMR) data and evidence into policy remains limited in many low- and middle-income countries (LMICs) in Asia and Africa, despite expanded investments being made in AMR surveillance and research. This is due to fragmented governance, weak knowledge translation capacity, and insufficient Results: Participant surveys showed improved confidence and capability to synthesize, interpret, and apply AMR evidence to inform policy. The four countries highlighted persistent constraints such as sectoral silos, limited institutional ownership, and gaps in evidence-use systems, but reported enhanced cross-sectoral collaboration and a clearer, replicable process for EBP development. Methodology: During Phase II of the Fleming Fund-resourced Regional AMR Data Analysis for Advocacy, Response, and Policy (RADAAR) project, a structured, hybrid, evidence-to-policy (E2P) capacity-strengthening model was implemented in Bhutan, Ghana, Kenya, and Lao People’s Democratic Republic, combining online and in-person training, targeted mentorship, and policy engagement. Each country developed a country-specific evidence brief for policy (EBP) and conducted policy dialogues to facilitate stronger decision maker involvement. Conclusions: RADAAR’s approach strengthened the foundational capacity for evidence-informed policymaking and demonstrated the value of institutionalized knowledge translation mechanisms. Sustained investment in E2P systems is essential to bridge the AMR E2P gap and ultimately support AMR prevention and control. Full article

Salt marshes are intertidal ecosystems that provide valuable services like wave attenuation, nutrient cycling, and carbon sequestration. Unfortunately, due to a combination of factors linked to global climate warming and increased coastal development, expanses of salt marshes are being lost worldwide. This has prompted coastal land managers to seek effective techniques to enhance salt marsh growth with changing environmental conditions. We examine how restoration of fringe oyster reefs, a commonly used technique to increase sediment accretion and erosion control in salt marshes, affects marsh migration and area change over time. Salt marsh vegetation movement was determined through analysis of aerial imagery collected by unmanned aerial vehicle (UAV) surveying before and in the months following restoration at a salt marsh island in Liberty County, GA, USA that underwent oyster reef restoration in September 2023 at three sites, each spanning ~25 m of shoreline. Results after one year showed all restoration sites experienced continued growth at greater rates than nearby unrestored control sites, despite environmental differences between sites. Our results provide evidence that oyster reef restoration may be a viable method for mitigating the loss of salt marshes in coastal Georgia. Full article
