The Universidad de Sucre (Unisucre) is a public, departmental, coeducational university located in Sincelejo, Sucre, Colombia. The university has three campuses in the city. The main one, known as the Puerta Roja is the home for most of the faculties and has the largest student population. The second and smaller campus, known as Puerta Blanca, is home to the Faculty of Health Sciences and it's near the University Hospital of Sincelejo. The third campus, known as Puerta Verde or the Granja Pericos is home to the Faculty of Agronomy Sciences and is in the outskirts of the city. The university offers education at undergraduate and postgraduate levels, with 16 academic programs across its five faculties..
In the research and development of constructed wetland technology, it is known that various plant species have the ability to remove waterborne pollutants. Therefore, this study aims to conduct a scientometric analysis of the use of emerging ornamental plants in constructed wetlands for wastewater treatment in tropical and subtropical regions. Through a systematic review, we identified ornamental plant species capable of removing water pollutants, the countries employing them, and their capacities for removing specific contaminants in different types of wetland systems. A search was conducted in key academic databases, using terms related to the use of ornamental plants in wetlands, their pollutant removal capacity, and the systems employed in tropical and subtropical regions. The studies included show that various ornamental plant species are capable of removing water pollutants. Configurations involving individual or combined species were identified. Finally, conclusions are presented to highlight gaps in the research and future opportunities, with the goal of creating a knowledge base to support the implementation of these systems in tropical and subtropical regions.
IntroductionCheilolejeunea is a pantropical genus with approximately 130 species, 55 of which are currently recognised in the Neotropics. Recent phylogenetic and taxonomic studies have laid the groundwork for biogeographical research on the genus. Building on these advances, the present study explores the phytogeographical relationships and climatic affinities of the Neotropical Cheilolejeunea species.MethodsWe investigated the distribution of the species of Cheilolejeunea within the Neotropics and the climatic factors that might have influenced their distribution, using databases of species distribution, geographical information systems tools, environmental variables, and multivariate analyses.Key resultsCheilolejeunea species in the Neotropics were found to be distributed from sea level up to 4400 m but appeared to have diversified mainly at elevations below 2000 m. Areas of maximum species density were identified in the Atlantic Forest (Brazil), northern South America (Colombia), and southern Central America (Costa Rica and Panam & aacute;). The distributions were mainly influenced by environmental variables related to humidity, with considerable variation in orography. Species diversity appeared to be favoured by turnover in mountainous regions. Endemic species appeared to be associated with regions of high overall species richness.ConclusionsThe distribution of Cheilolejeunea species in the Neotropics is primarily shaped by geographical and environmental factors, with altitude and humidity emerging as key determinants. These factors may have contributed to a relatively high endemism rate, with approximately 25% of species restricted to a single biogeographical province.
Digital photoelasticity enables non-contact, full-field stress analysis through optical fringe patterns, yet its practical deployment is often constrained by experimental complexity and the limited availability of open, standardized datasets. The emergence of multi-polarizer array cameras provides polarization-resolved measurements with high information content, enabling advanced analysis strategies beyond conventional single-image approaches. This work presents a public experimental dataset composed of synchronized image sequences acquired using a polarizer array camera and a conventional RGB camera under incremental mechanical loading. The dataset comprises nine experiments, including four benchmark specimens and five bio-inspired geometries, each recorded over 720 load steps. In total, the dataset releases 25,920 polarization-resolved images and 6480 RGB images, all provided in lossless format and accompanied by experiment-specific segmentation templates. Although classical and hybrid load-stepping methods are used to demonstrate the utility of the dataset, its scope is not limited to this application. The dataset is intended as a flexible platform for exploring a wide range of photoelastic analysis techniques that leverage polarization information, while enabling direct comparison with conventional color demodulation techniques.
Purpose This research investigates the mediating role of accounting information quality in the relationship between internal accounting controls and operational profitability in resource-constrained microenterprises. It focuses on 60 firms in Barranquilla, Colombia, during the 2023 fiscal year. Design/methodology/approach The study employs a COSO-based internal control assessment and applies accrual-based accounting quality measures. Statistical techniques include Spearman correlation, hierarchical regression, quantile regression and mediation analysis using structural equation modeling. Data validation was performed through triangulation with tax records and banking documents. Findings Internal controls explain 31% of the variance in accounting quality, which mediates 52% of the variance in profitability. Risk assessment shows the strongest association with accruals quality (rs = 0.612, p < 0.01). Quantile regression reveals that low-performing firms benefit the most from improved controls. Research limitations/implications Findings suggest targeted internal control enhancements can improve financial outcomes in microenterprises. Results offer insights for policymakers, auditors and SME development programs in emerging economies. Originality/value This is among the first empirical studies in Latin America to validate a mediation model linking internal controls, information quality and profitability in microenterprises using a rigorous multi-method approach.
This study investigated how trust moderates the relationship between asset tokenization and liquidity access among 59 microenterprises in Barranquilla and Cartagena, Colombia. Through hierarchical regression, quantile regression, and latent profile analysis, the research found that while tokenization improved liquidity access, this effect depended critically on trust in decentralized platforms, particularly governance trust. Microenterprises with high technical trust but low governance trust showed substantially limited liquidity benefits despite active tokenization implementation. This effect was strongest for financially constrained businesses (beta = 0.42 at 25th liquidity percentile vs. beta = 0.19 at 75th percentile). Four distinct enterprise profiles were identified, with "Comprehensive Trust Adopters" achieving superior outcomes compared to "Technical Trust Dominant" enterprises despite similar implementation levels. The findings suggest successful tokenization requires attention to both technical implementation and governance trust development, especially in contexts with limited traditional financing options.
