PublicaciónImpact of digital literacy on the adoption of precision agriculture and its effect on the sustainability of rice cultivation in Lambayeque(Frontiers Media SA, 2026-02-01)The transition to more sustainable and climate-resilient agriculture is an urgent challenge in agricultural regions of developing countries such as Lambayeque (Peru), especially in rice cultivation. In this context, digital literacy is emerging as a key enabler for accessing climate data, adopting precision agriculture technologies, and implementing sustainable agricultural practices. However, there are gaps linked to sociodemographic variables such as age, which can moderate these technology adoption processes. The objective of this study was to analyze the patterns of association between digital literacy, access to finance, risk perception, and the adoption of sustainable agricultural practices, and to examine whether age moderates the association between digital literacy and access to climate data. To this end, a quantitative, non-experimental approach was applied, using Partial Least Squares Structural Equation Modeling (PLS-SEM). The sample consisted of 101 rice farmers in the Lambayeque region, who were given a validated questionnaire that included five theoretical constructs measured using Likert scales. The results of the structural model confirmed that digital literacy has a positive and significant association with access to climate data (β = 0.461, p < 0.001) and with the adoption of sustainable agricultural practices (β = 0.259, p = 0.015). A positive association was identified between access to finance and risk perception (β = 0.411, p < 0.001). Age was negatively associated with digital literacy (β = −0.196; p = 0.027); however, the formal moderation test (DL × Age) was not significant (β = −0.054, p = 0.421), so there is no evidence that age moderates the association between digital skills and access to climate information. These findings support the design of differentiated interventions that incorporate intergenerational digital training, inclusive financing policies, and hybrid technology transfer strategies tailored to access gaps. Taken together, the evidence is consistent with the idea that reducing the digital divide can strengthen agricultural sustainability and climate resilience in rural contexts in Latin America.

This study aimed to evaluate OEO’s chemical composition and antimicrobial activity in vitro against S. aureus and E. coli. Methods: The composition of OEO was determined by gas chromatography–mass spectrometry (GC-MS). Results: Compounds included monoterpenes with known antimicrobial activity, such as 2-menthen-1-ol (36.33%), linalyl acetate (9.26%), terpinene-4-ol (9.01%), 4-thujanol (6.33%), menthen (5.81%), sabinene (5.18%), and carvacrol methyl ether (5.14%). Conclusions: OEO had a strong antimicrobial activity with a minimum inhibitory concentration (MIC) of 1.90 mg/mL for S. aureus and 0.49 mg/mL for E. coli after 18 h incubation. The minimum bactericidal concentration (MBC) was 7.9 mg/mL against S. aureus and 0.99 mg/mL against E. coli. Thus, OEO could be used as a natural antimicrobial against S. aureus and E. coli infections.

PublicaciónAplicación del ultrasonido para conservar las propiedades antioxidantes de la pitahaya(Latin American and Caribbean Consortium of Engineering Institutions, 2024-01-01)Pitahaya fruit has a considerable content of antioxidant and nutraceutical substances. Traditional techniques and thermal treatments used in fruit processing alter the phytochemical and nutritional components and limit their utilization, so a modern and suitable technology was sought to help preserve its components, finding ultrasound as one of the techniques that favors the preservation of the nutritional properties, bioactivity and antioxidants of the fruit pulp and its derived or processed products. In the processing of the pitahaya, the pulp was extracted by cutting it into slices and freezing it at -50°C, then freeze-drying it for about 49 hours. The dry ground sample was macerated in methanol for 7 days, separated into portions to determine the antioxidant capacity by DPPH method and analyzed by spectrophotometer. In a filtered portion, the antioxidant capacity was determined directly, and other portions were subjected to ultrasound before analysis, evaluating the times, power and frequency of application in order to preserve the natural antioxidant and nutritional composition of the pulp; it was found that the sample to which ultrasound was applied for 20 minutes at 180 W power and 40 kHz frequency was the most relevant to preserve the antioxidant capacity of the pitahaya pulp. © 2024 Latin American and Caribbean Consortium of Engineering Institutions.

PublicaciónModels for R+D+i+e interaction between the university and its context. A Literature Review(Latin American and Caribbean Consortium of Engineering Institutions, 2024-01-01)The interaction of the university and its context determines the policies to ensure that research and development (R+D) have a positive impact on society. However, innovation and entrepreneurship (I+E) have been generating new scenarios and policies in the university. The aim of this study is to identify models for R+D+i+e interaction between the university and its context. In this research, a systematic mapping study (SMS) was performed in five digital libraries. In the process, 13,561 articles were obtained and 336 articles selected as primary studies. In the literature, 17 interaction models for R+D+i+e interaction between the university and its context were identified. The most reported models are: Industrial University, Triple Helix, Entrepreneurial University, Open Innovation and Stakeholders. Likewise, the main types of activities linked to the identified models are: research, innovation and the combination of research and development. In contrast, there are few for experimental development and entrepreneurship. © 2024 Latin American and Caribbean Consortium of Engineering Institutions. All rights reserved.

PublicaciónCOVID-19 Preventive Measures Among Artisan Women Working with Native Cotton in a Protected Natural Area(CEUR-WS, 2022-01-01)The COVID-19 pandemic has significantly affected the tourism sector globally. In recent years, tourism in Peru experienced sustained growth, and the natural protected areas (ANP Areas Naturales Protegidas) became consolidated into main tourist destinations. Nevertheless, vulnerable groups like artisan workers have suffered more acutely from this crisis. This study was conducted in the buffer zone of the Bosque de Pómac Historic Sanctuary, with the study population being the artisan women of the native cotton weaving line (of the scientific name of Gossypium barbadense L., a trade product native to the area, which is in the process of extinction and was used by ancestral cultures). The objective of this study is to describe the socio-demographic profile and the compliance with preventive measures against COVID-19 of artisan women for tourism recovery. The research has a quantitative, descriptive-cross-sectional approach. A checklist was given to 30 artisan women specifically from the Jotoro-Jayanca, Pómac III-Pitipo, and Túcume population centers. To test the content validity of the instrument, Aiken's validity coefficient was chosen with 10 assessors who were experts in health and tourism; the items were fully approved and statistically significant (Aiken's V = 1, p = 0.0 01). The data was processed with IBM SPSS version 25, using descriptive statistical techniques. The results showed that 93.3 of the artisans had their vaccination doses and 70% are still not complying with preventive measures such as hand washing, the use of masks, and social distancing required by COVID-19 on behalf of the Peruvian state. It is concluded that interventions are needed to apply protocols when tourism has recovered for personal, family, and community care. © 2022 Copyright for this paper by its authors.

PublicaciónSustainability in undergraduate course curricula at Andalusian (Spain) universities: a critical analysis(Frontiers Media SA, 2024)Education is one of the main tools used to implement sustainable development goals (SDGs). Higher education institutions (HEIs) have a major social responsibility regarding sustainability given the relevance and impact of their educational work and the creation of knowledge through their research. Sustainability is promoted and linked to values, teaching-learning methodologies, and studying of global–local problems. Within this framework, the objective of our research is to determine the presence and means by which sustainability appears in the course curricula of university bachelor’s degrees of the public universities of Andalusia (Spain). The study used quantitative methodology. As in other studies, major deficiencies have been revealed in terms of the inclusion of sustainability in the universities, determining a limited presence of local problems to address sustainability. Thus, Andalusian universities distance themselves from the society and community in which they exist. This may also limit student knowledge of sustainability issues in which they could potentially be relevant participants.
