This study analyzes the revealed comparative advantage (RCA) of citrus exports from the main exporting countries to the U.S. market during the period 2005–2024. The specific objectives were to identify the revealed comparative advantage (RCA) of the main exporters (Peru, Mexico, and Colombia) to the U.S. market during the same period. The methodology used is applied, with a descriptive quantitative approach, a nonexperimental design, and a longitudinal cross-sectional framework. The data set consisted of citrus export data (2005–2024) compiled from the TRADE MAP platform. The results showed that Peru achieved the highest revealed comparative advantage, with an average of 2.11, peaking at 4.36 in 2022. In comparison, Mexico obtained an RCA of 1.14 and Colombia recorded 1.07. It is concluded that Peru ranks as the leading country in terms of competitiveness and export specialization, confirming the proposed hypothesis.

The article shows nonlinear regressions of five cases of the agricultural sector in Panama, specifically the hectares of sowing are related to the harvest in quintals. The correlation and determination coefficients are determined for each of the five cases and in each case the period with greater efficiency is estimated, that is, the one with the greatest number of quintals harvested in a smaller planting area as a measure of productivity. An analysis and discussion of the results is carried out and the conclusions are presented.

This systematic review synthesizes recent evidence on how agroecology is scaled and how its performance is measured in sustainable agrifood systems, with emphasis on actionable insights for research, practice, and policy. Following PRISMA 2020, we searched Scopus and Web of Science for peer-reviewed studies published between 2017 and 2026, and appraised methodological quality using MMAT (2018). Fourteen eligible studies spanning global, continental, national, and territorial/local scales were included. Findings show that scaling is less dependent on technical “packages” and more on enabling conditions: (i) multi-level governance and multi-actor networks that mitigate structural lock-ins; (ii) financing reoriented toward territorial transitions and local economies; and (iii) short supply chains and circular strategies that reinforce resilience and socio-economic cohesion. Regarding measurement, the literature remains heterogeneous, yet a clear trend emerges toward integrative assessment frameworks and comparable metrics (e.g., TAPE-based approaches and adaptations using secondary datasets) to monitor environmental, social, and productive performance. We propose a minimum core set of indicators and reporting elements to improve comparability across contexts, strengthen evidence-based decision making, and accelerate agroecological transitions.

In recent years, climate change has emerged as one of the main threats to food security, especially in vulnerable regions like Honduras. There, the agricultural sector faces increasing negative impacts due to changing climatic conditions. For this reason, the present study evaluated the impact of climate variability and climate change on potato production in Azacualpa, a village located in Francisco Morazán department. To achieve this goal, climate data from local meteorological stations (Azacualpa and the Uyuca Biological Reserve), reanalysis products (ERA5-Land and (ERA5-Ag), and climate projections for the year 2050 under the RCP 6.0 scenario Intergovernmental Panel on Climate Change (IPCC) were used. The simulation was conducted using the AquaCrop® agricultural model. Te results showed that climate variability, particularly events associated with the ENSO phenomenon affect potato yield under rainfed conditions. During the dry season, yields were below 15 t/ha in the Niño, Niña and Neutral years due to limited water availability. Likewise, projections for 2050 indicated a slight decrease in yield, due to sustained temperature increases and their negative effect on crop development. In conclusion, the study demonstrates climate variability and climate change both negatively affect potato production in Azacualpa. However, the strategic use of irrigation and the analysis of future scenarios can help identify adaptation measures that enhance the resilience of the agricultural system under changing climate conditions.

This study aimed to evaluate the effect of sous-vide cooking at moderate temperatures on beef steak quality and shelf life. Thermal lethality was assessed using Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 inoculated into vacuum-packaged steaks cooked at 55, 60, and 65 °C for 0, 20, 40, 60, and 80 minutes. Decimal reduction times and lethally equivalent time–temperature combinations were determined: 55 °C × 60 min, 60 °C × 55 min, and 65 °C × 50 min. These conditions were applied to evaluate physicochemical quality (pH, water-holding capacity, cooking loss) and sensory texture. The treatment at 55 °C for 60 min was selected due to its higher water-holding capacity and lower weight loss. Treated steaks were stored under refrigeration (3 ± 2 °C) for 60 days, during which physicochemical (pH), sensory (color, odor, appearance, flavor, texture), and microbiological parameters (mesophilic aerobes, Staphylococcus aureus, coliforms, E. coli, Salmonella spp.) were monitored to estimate shelf life. pH values did not differ significantly among cooking treatments, and the texture of steaks cooked at 55 °C and 60 °C was comparable. The limiting factor for shelf life was the mesophilic aerobic count, resulting in an estimated 67-day shelf life under refrigeration. In conclusion, sous-vide cooking at 55 °C for 60 minutes ensures optimal physicochemical and sensory quality and extends the shelf life of beef steaks by approximately 60 days compared to conventionally cooked products, demonstrating its potential as an effective technology for improving meat quality and safety.

The primary objective of the research was to determine the relationship between knowledge management, strategic management, and capacity for internationalization in a telecommunications company within an emerging economy. The study’s methodology was based on a quantitative, applied approach with a correlational scope and a non-experimental cross-sectional design, in which the main variables were knowledge management, strategic management, and capacity for internationalization. The study population consisted of 54 employees of the telecommunications company; the method used was a survey, and the instrument was a questionnaire. The results showed a significant relationship between strategic management and capacity for internationalization. Therefore, it is concluded that although knowledge management did not show significant relationships within the analyzed model, strategic management does position itself as the fundamental axis for driving capacity for internationalization, becoming the most relevant component for business growth and competitive projection in international settings.

This experimental and quantitative study, conducted in the laboratory of the Universidad Privada del Norte-Cajamarca, focused on analysing the ecotoxicological impact of tartrazine (synthetic azo dye E102), present in commercial mustards, on the survival and behavior of water fleas (Daphnia magna). Daphnia magna is a bioindicator sensitive to aquatic toxicity, and the objective was to provide evidence of the risk posed by this emerging contaminant when released into aquatic ecosystems.

To this end, Daphnia magna neonates were exposed to solutions of three brands of mustard (A, B, C) and a control group (distilled water) for 15 days. The results demonstrated an acute and significant toxic effect, with total mortality (100%) recorded in the mustard treatments by day 13 of exposure. In addition tolethality, morphological changes were observed, such as intense yellow pigmentation of the body, loss of transparency, deformation of the shell, and reduced mobility.

In conclusion, the findings confirm that the concentrations of tartrazine present in commercial products may exceed ecotoxiclevels, posing a potential risk to aquatic ecosystems and highlighting the need to regulate the discharge of these synthetic dyes.
