Servicification—defined as the services value added embodied in goods—has been studied mainly in manufacturing, but its role in agricultural exports is less understood. We measure servicification in agricultural exports and examine how it is associated with export performance, upstream linkages and upgrading-related proxies. Using trade-in-value-added accounting for 80 countries (1995–2022), we estimate two-way fixed-effects panel models with exporter-clustered standard errors. Higher servicification is associated with both larger and intermediate agricultural value-added exports within countries over time. Decompositions show that these relationships are driven by services produced domestically, which are a location-based measure that may include services supplied by foreign-owned affiliates operating locally. Foreign services value added is not systematically related to outcomes. Servicification is also associated with a smaller agriculture-to-economy value-added gap proxy, and embodied financial and Information and Communication Technology (ICT) services appear complementary. Labour-market results for a smaller subsample are suggestive of stronger links with skill-intensive employment shares at lower GDP per capita levels. Because reverse causality cannot be ruled out, the findings are interpreted as conditional associations that motivate future causal identification. Full article

Regulatory bodies have observed an increase in environmental issues due to firms’ interactions with the environment. Nonetheless, reconciliation actions are emerging, driven by the pursuit of sustainable development goals. This study investigated the impact of financial development and foreign direct investment on ecological footprints in sub-Saharan African nations, while examining the mediating role of regulatory quality and control for corruption. The research was motivated by the growing environmental degradation in the region amid growing capital inflows and financial market expansion. Using panel data of 18 sub-Saharan African countries between 1996 and 2023, sourced from the World Bank database and World Governance Indicators, we employed an Autoregressive Distributed Lag model to assess the short- and long-run relationships among ecological footprint, financial development, foreign direct investment, and key institutional factors. Results from the baseline model show that financial development significantly increases ecological footprints, while the effect of foreign direct investments is insignificant in the absence of institutional factors. However, when mediating variables are introduced, foreign direct investment significantly worsens ecological footprint, and regulatory quality and control for corruption show strong moderating effects, confirming the pollution haven hypothesis. Also, all control variables (trade openness, gross domestic product per capita, government expenditure, and population density) show significant outcomes with environmental sustainability. The findings underscore the importance of institutional factors in shaping sustainable foreign direct investment flows and financial systems. These research findings offer policy pathways for aligning investment strategies with sustainability goals in sub-Saharan Africa. Recommendations include strengthening the nation’s institutional framework, linking foreign direct investment to environmental compliance and promoting green finance policies across the region.

The extensive diversification of flower shape and organs underpins the adaptive success of angiosperms. Despite substantial knowledge of the molecular mechanisms controlling flower induction and development, few studies have quantified the variability in floral traits within species or explored their correlation with other reproductive traits. In cultivated tomato (Solanum lycopersicum L.), human selection has driven fruit diversification in terms of size and shape. In the present study, 48 landraces representing tomato diversity in reproduction-related characteristics were phenotyped for 18 flower structural or dimensional traits. Flower traits exhibited lower coefficients of variation compared to other reproductive traits, though organ numbers showed high heritability values. Flower organ number and size were tightly correlated, but the correlation between dimensional traits was weaker. This likely reflects the selective pressures on pistil traits during domestication, including specific mutations affecting carpel number and ovary morphology. While ovary and fruit size were positively correlated, no relationship was found between ovule and seed size, suggesting that genes related to seed size generally act after fruit set. The collection was genotyped at the Fasciated (Fas) locus, and 13 floral traits were significantly different in fas mutants. The phenotypic variability described in this study could help breeders select for more fertile flowers and assist reproductive biologists in linking genes to flower development. Full article

This study proposes a novel theoretical synthesis, bridging the sociology of lived religion with economic club good theory to explore the high-commitment dynamics in domestic spheres in the analysis of “Amen meals”, a rapidly spreading ritual among Jewish women. Using a qualitative–ethnographic methodology based on 23 participant observations and 53 in-depth interviews with a diverse spectrum of Jewish women in Israel, the research examines the ways this ritual functions as a gendered religious economy. The findings identify emotional stringency as a key mechanism for communal cohesion: unlike traditional religious clubs that filter out free riders through external prohibitions, this economy demands a tariff of emotional exposure and vulnerability, where public tears serve as costly signals of commitment. These enable the participants to gain access to exclusive club goods such as social insurance and spiritual agency. The study concludes that Amen meals challenge the binary between institutional–rational and private–emotional spheres, positioning women’s ritual creativity as a mutual insurance system for risks that formal institutions fail to cover. It reveals the powerful economies operating within the lived religion of women. Full article

This study examines the effects of Gross Domestic Product (GDP) per capita, its squared and cubic terms (GDP² and GDP³), renewable energy, fossil fuels, nuclear energy, and research and development (R&D) on environmental sustainability in G20 countries from 1994 to 2023, with a specific focus on testing the N-shaped Environmental Kuznets Curve (EKC) hypothesis. CS-ARDL serves as the baseline estimator, and robustness is checked using FMOLS and DOLS estimators and an alternative dependent variable, greenhouse gas (GHG) emissions. The coefficients of GDP, GDP², and GDP³ follow the expected +, −, + pattern of a cubic specification, indicating nonlinear income–environment dynamics. However, the implied turning points are not observed within the sample range, suggesting that a full N-shaped EKC trajectory is not empirically supported for G20 countries. Renewable energy consumption and R&D investment have negative coefficients, suggesting they help reduce environmental degradation. Fossil fuel consumption significantly increases ecological pressure, whereas nuclear energy shows a positive but insignificant effect. The findings remain robust across alternative estimators and when GHG emissions are used. Overall, the findings indicate that economic growth alone cannot ensure environmental sustainability, underscoring the need for renewable energy expansion, technological innovation, and reduced reliance on fossil fuels.

Intraspecific phenotypic diversity in clonally propagated crops is frequently constrained by narrow domestication histories and the widespread use of a limited number of elite cultivars. In Stevia rebaudiana, commercial production has largely centred on cv. ‘Morita II’, raising concerns about reduced diversity and adaptive potential. This study characterised and structured phenotypic diversity within a segregating population derived from ‘Morita II’ under tropical field conditions. Eighty-six progeny-derived genotypes (clonally propagated) plus the commercial control (87 genotypes total) were evaluated using 25 agromorphological descriptors (qualitative and quantitative). Quantitative traits showed broad variation, including plant height (28.26–119.50 cm) and dry yield rate (0.94–28.55 g plant⁻¹). Multivariate analyses of mixed descriptors (PCA and hierarchical clustering based on Gower distance) identified plant architecture, vegetative growth, and phenology as the main sources of differentiation. The first two principal components explained 19.65% and 12.58% of total phenotypic variance, respectively (32.23% cumulative). Hierarchical clustering (UPGMA; dissimilarity cut-off = 0.25) resolved four phenotypic groups (GI–GIV) with sizes n = 3, 1, 66, and 17, respectively, enabling the definition of contrasting ideotype candidates based on recurrent trait combinations. These results provide a quantitative baseline for phenotypic structuring, prioritization of materials for further evaluation, and management of clonal stevia collections in tropical production systems. These ideotype candidates should be considered preliminary until validated across environments and linked to chemical quality traits. Full article

This study presents a comprehensive regional analysis of the COVID-19 pandemic’s impact on tourism in Slovakia during 2018–2024, employing rigorous statistical methods to quantify sectoral transformations. Based on extensive data on visitor arrivals, revenues, and accommodation facility utilisation across eight NUTS III regions, the analysis identifies four distinct regional tourism clusters characterised by differentiated recovery trajectories. Paired t-tests confirmed statistically significant changes in international tourist arrival indices across seven regions (p < 0.05), validating fundamental structural reorientation in tourism demand. The findings reveal pronounced heterogeneity in recovery patterns: while the Bratislava Region and the Žilina Region achieved substantial revenue growth (46.04% and 146.54%, respectively), domestically oriented regions (Banská Bystrica, Košice, Nitra, Prešov, and Trenčín) demonstrated minimal recovery (8.19% aggregate growth). Critical findings include the persistence of passive tourism dominance (94.09% of national revenues), declining international competitiveness from traditional Western European source markets, and compensatory expansion from emerging markets (USA +398.73%, Oman +234.68%, and Poland +226.55%). The ANOVA analysis revealed no statistically significant differences between regional indices in 2024 (p = 0.362), indicating market stabilisation despite differentiated trajectories. The study emphasises the necessity of regionally calibrated sustainable strategic interventions to diversify experiential tourism, activate the domestic market, and enhance technological infrastructure to build sectoral resilience against future exogenous shocks.

The last few decades have provided mounting evidence that dogs are not only able to behave in intelligent ways but also that they have the capacity to make inferences by associating visible and imagined events. In particular, the kinds of inferences shown by dogs elevate them to ‘Popperian animals’, which are rational in the sense of being able to conduct trials and errors in the head. Here, I review a selection of studies with dogs that fulfil this attribution. Dogs have been found capable of (a) making inferences by exclusion, with both computer images and word-object associations, (b) drawing inferences about the efficiency of the observed methods, the situational constraints of the situation, and the goals of the model in the course of selective (‘rational’) imitation, and (c) going beyond directly observable cues when inferring the intention, the knowledge, or even the beliefs of humans in perspective-taking tasks. Despite the contamination with ambiguous data, open questions, and current debates about the possession of (non-linguistic) mechanisms for creating mental representations of the mental states of others (called mind reading), we may safely assume that domesticated dogs have become Popperian animals equipped with the cognitive tool set of inferential thinking and perspective taking.

Illegal dumping is a significant environmental and public health challenge in South African townships. This study investigates the drivers of illegal dumping in Ngwelezana Township, KwaZulu-Natal, using a qualitative case study approach. Data were collected through semi-structured interviews with municipal officials, waste workers, and community stakeholders, supplemented by field observations and document analysis. Qualitative content analysis identified that dumping is driven by a misalignment between waste generation and service provision, characterized by ‘institutional incoherence’ and ‘constrained compliance.’ Specific drivers include weak enforcement capacity, inadequate municipal resources, high disposal and transport costs, and the availability of unmanaged open spaces. The findings suggest that current reactive clean-up approaches are insufficient to address the systemic nature of the problem. This study proposes a transition toward preventative, community-centred waste governance that prioritizes strategic resource allocation, infrastructure accessibility, and integrated spatial planning. By analyzing the intersection of governance, cost, and infrastructure, this research provides a framework for addressing waste mismanagement in comparable Global South contexts. Full article

This study investigates whether external terms of trade (TOT) and mining-sector GDP in Peru share a stable long-run relationship. Although mining has played a central role in the country’s growth trajectory, its performance remains highly exposed to international price cycles, raising questions about its structural sustainability under persistent external shocks. Using quarterly data for 2001–2024, the analysis applies Johansen cointegration techniques and estimates a bivariate Vector Error Correction Model (VECM) to evaluate long-run co-movement and short-run adjustment dynamics. The results identify a single cointegrating relationship in which mining GDP acts as the primary adjustment variable, gradually correcting deviations from long-run equilibrium, while short-run TOT shocks do not exert direct contemporaneous effects on mining growth. The estimated speed of adjustment is low, suggesting a prolonged convergence process consistent with the capital-intensive and rigid structure of the mining sector. Robustness exercises—including estimation with heteroskedasticity and autocorrelation consistent (HAC) standard errors and an extended specification incorporating gross fixed capital formation—confirm the stability of the long-run relationship. These findings indicate that the structural sustainability of mining output depends on the interaction between external price dynamics and the sector’s capacity to adjust to persistent international shocks. The study concludes that, in the Peruvian case, structural sustainability in the mining sector is not determined solely by global price trends, but is also conditioned by domestic productive and institutional factors that govern the speed of adjustment in the presence of sustained external volatility.

This study investigated the relationship between digital governance and sustainable development across the European Union (EU-27) during the period 2015–2023. Although digital transformation has become a central policy priority, empirical evidence on how e-government adoption contributes to sustainability performance remains limited. Using panel data from Eurostat and the UN Sustainable Development Solutions Network, the analysis employed advanced econometric techniques, including Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), and Method of Moments Quantile Regression (MMQR), to explore both long-run relationships and heterogeneous effects across countries. The model incorporates key indicators such as the percentage of individuals using e-government services, Gross Domestic Product (GDP) per capita growth, and Research and Development (R&D) expenditure, capturing, respectively, digital governance adoption, innovation potential, and economic capacity, as essential drivers of sustainable development. Results indicate a strong and statistically significant positive association between digital governance adoption and sustainable development outcomes. The quantile regression analysis reveals that this effect is more pronounced in countries with higher innovation intensity and stronger economic capacity, suggesting that digital governance amplifies sustainability benefits in countries with more advanced institutional and technological infrastructures. Robustness checks confirm the stability of the findings across multiple estimation techniques. The results underscore the need for inclusive and innovation-driven digital strategies to ensure that the benefits of digital governance are equitably distributed, ultimately enhancing the EU’s progress towards the Sustainable Development Goals.

Neoplasia of the cornea is overall rare, with corneal squamous-cell carcinoma (c-SCC) being most commonly reported in all species. C-SCC pathogenesis has been related to UV exposure in humans and horses, and to papillomavirus infection in humans. In dogs, brachycephalic conformation and chronic keratitis were associated with c-SCC. Corneal vascular tumors have also been exceptionally reported in humans, and rarely in animals. In dogs, they have been suggested to be UV-related. Except for equine c-SCCs, most studies on corneal neoplasms are case reports. The present study aimed to review the literature on epithelial and vascular corneal tumors in dogs, cats, and horses, adding new cases from our archives. Pubmed and Web of Science were searched (1980–2025) using the following keywords: cornea, neoplasia, carcinoma, hemangioma, hemangiosarcoma, dog, cat, and horse. Additionally, 94 new cases of corneal neoplasia were retrieved: 47 dogs (40 epithelial and seven vascular); 29 cats (14 epithelial and 15 vascular) and 18 horses. Signalment, clinical history, and histopathological characteristics were analyzed and compared with the literature. The combined results supported a strong association between brachycephalic dogs and c-SCC occurrence and highlighted the frequent coexistence in the feline species of symblepharon and corneal perforation, with corneal tumors.

Botulism is a neuroparalytic disease caused by exposure to botulinum neurotoxins produced by anaerobic spore-forming bacteria of the genus Clostridium. This disease occurs in both humans and wild and domestic animals, and is currently becoming an increasingly serious problem worldwide due to high animal mortality and economic losses. The clinical signs observed during the progression of botulism are nonspecific and difficult to unequivocally associate with this disease entity. The aim of this study is to present laboratory diagnostics of suspected botulism cases reported in Poland in 2022–2024, as well as to present the challenges encountered during laboratory investigations. The material for the study consisted of samples of liver, serum, digestive tract, feed, feces, straw, and water from drinking lines, sent to the National Veterinary Research Institute (NVRI) in relation to thirteen suspected cases of botulism, predominantly reported in poultry, but also in mink and cattle farms. The samples were analyzed using a mouse bioassay and conventional culture methods, as well as real-time PCR methods aimed at detecting the ntnh and bont genes, which determine the production of botulinum neurotoxins. Of the thirteen suspected cases analyzed, ten were confirmed by the detection of botulinum toxin (BoNTs) and/or the presence of the ntnh and bont genes in the tested material. Based on the results obtained, it was concluded that botulinum toxin type C was the etiological factor of botulism poisoning in most of the analyzed cases. In one case reported in cattle, poisoning occurred as a result of the mosaic variant of BoNT D/C. Due to the nonspecific signs of botulism and the time required for them to appear, laboratory diagnostics play a key role in detecting the disease. However, this process is complicated due to the high heterogeneity observed among Clostridium spp. strains, as well as difficulties encountered during the isolation of the microorganism and the possibility of loss of toxin-producing capacity at later stages of analysis.

Owned house cats negatively affect wildlife when roaming outdoors, yet it remains unclear whether their movements are determined by selection for specific land cover types. We GPS-tracked 49 neutered, owned cats with daily outdoor access in a Mediterranean habitat, monitoring each for seven days. For each cat, we created a detailed, fine-scale land cover map from near-contemporaneous aerial imagery. We delineated each cat’s home range and compared its land cover composition to that of an equal-area circle centered on the median x and y coordinates of GPS fixes, representing directionally unbiased (isotropic) roaming. Home ranges were small (mean 0.85 ± 0.06 ha; median 0.73 ha; approximately 50 m radius), and cats whose ranges included nearby natural or semi-natural open areas had larger home ranges than cats in urban environments. Home range size was not affected by sex or season and decreased with age. Despite detailed, accurate mapping, no land cover class was found to be over- or under-represented within cat home ranges relative to the null expectation. These results, although limited to harness-tolerant cats, suggest that owned cats in our study area do not preferentially select specific land covers when roaming outdoors. Full article

Service encounters have long been viewed as determinants of hotel guest loyalty, yet excellent service does not always translate into repeat patronage. This study examines how green service encounters shape guest loyalty in green-certified luxury hotels in Bali, a leading sustainable tourism destination. It investigates whether green experiential value and green customer delight mediate the effect of green service encounters on green hotel loyalty. Survey data from 273 domestic repeat guests of Green Globe and Earth Check-certified luxury hotels in Bali were analyzed using partial least squares structural equation modeling (PLS-SEM). The results show that green service encounters influence loyalty primarily through green experiential value and green customer delight, with delight exerting a comparatively stronger mediating effect. The study extends green hotel loyalty research by theorizing and testing an emotion-centric, sustainability-anchored loyalty mechanism beyond traditional service-quality and satisfaction models. Managerially, the findings highlight the need for certified luxury green hotels to design green service encounters that create distinctive experiential value and delight, thereby strengthening long-term guest loyalty.
