La mosca soldado negra (Hermetia illucens, Diptera: Stratiomyidae) representa una especie clave para la bioconversión de residuos en modelos de economía circular. No obstante, la eficiencia de su producción masiva está condicionada por el éxito en la fase de incubación. En este estudio se evaluó la tasa de eclosión de huevos bajo un Diseño Completamente Aleatorizado (DCA) con tres tratamientos y tres repeticiones por tratamiento. Las unidades experimentales consistieron en 50 huevos dispuestos en cajas Petri bajo condiciones controladas (27-30 °C y 60-70% de humedad relativa). Se compararon tres sustratos: residuos de frutas (T1), estiércol de vaca (T2) y una mezcla equilibrada de ambos (T3). Los resultados indicaron diferencias significativas (p < 0.05) entre tratamientos; la mezcla (T3) alcanzó el mayor porcentaje de eclosión con un 88.67%, seguida por el sustrato de frutas (T1) con un 76%. El estiércol puro (T2) mostró un efecto inhibitorio severo con solo un 4% de eclosión. Se concluye que La incubación de la mosca soldado negra es significativamente más eficiente utilizando mezclas de residuos de frutas y estiércol de vacuno que empleando estos sustratos de forma individual, ya que la combinación equilibrada de ambos maximiza la tasa de eclosión en sistemas de producción masiva.
Introduction: The risk of Digital Feudalism has been observed in the scientific, political, and economic development of Latin American societies. Here, complex thinking provides multipurpose analytical models that transcend the mechanisms imposed by global power centers. Methodology: A qualitative design, based on complex thinking and SRL. The information search focused on the Web of Science databases, Google Scholar, and Academia.edu platform, following the PRISMA technique and the construction of RAES. Results: The effects of Digital Feudalism go beyond the economic and political dimensions. Nonlinear feedback relationships are proposed between technology « dependency « surveillance, and others such as education « knowledge production. Conclusions: The impact of platforms is assumed to be a complex problem that can be overcome with the use of open-source alternatives and transnational synergies tailored to the needs and priorities of the global south. This includes the development of software, hardware, and platforms that guarantee intellectual and scientific production.
Este trabajo buscó comprender la interacción de las comunidades de La Dorada (Caldas, Colombia) con su entorno natural. Mediante un enfoque etnozoológico se recopiló la información a través de entrevistas semiestructuradas aplicadas a residentes del área de estudio. Los resultados revelaron que 57 especies de vertebrados son utilizados localmente en categorías como alimentación, comercio, medicina, uso como mascotas y prácticas mágico-religiosas. Los peces fueron el grupo más relevante, especialmente para el consumo y comercio, mientras que mamíferos, aves, reptiles y anfibios presentaron aplicaciones más específicas. Se destacó el conocimiento ancestral sobre propiedades medicinales para tratar dolencias respiratorias y reumáticas. Las percepciones hacia la fauna fueron mayoritariamente positivas, aunque el miedo hacia las serpientes evidenció actitudes ambivalentes. Se resaltó el valor cultural y ecológico de la fauna, como su papel en la regulación de ecosistemas y en la dieta local. Finalmente, la fauna silvestre es un bien clave para la subsistencia, la identidad cultural y la sostenibilidad económica en La Dorada. Sin embargo, la pérdida de biodiversidad y la disminución del conocimiento tradicional representan retos para la gestión integral de los recursos y el mantenimiento de la identidad biocultural local. Es recomendable fomentar la conservación mediante estrategias educativas, promoción de alternativas económicas sostenibles y preservación de saberes locales.
This article aims to analyze the formative tactics and conceptual categories of storytelling as an educational tool to improve marketing processes in rural communities and ethnic minorities in Colombia. The methodology consisted of a systematic bibliographic review of a descriptive-qualitative nature, based on academic documents published since 2019, located in university repositories and databases such as Google Scholar and Scopus.The results were organized according to the literature into two categories: "Marketing Education" and "Storytelling", with their respective subtopics, based on the central question: How does marketing education through storytelling impact peasant and minority groups in Colombia?The study identified that storytelling, in its digital, interactive formats and through social media, emerges as a potential strategy to empower rural and ethnic communities in Colombia. It adds value to their products and helps connect with broader markets without losing the distinctive narrative of each group.It was concluded that although there is growing interest in the topic, gaps remain in the literature regarding the concrete application and impact measurement of these tactics in rural and ethnic contexts in Colombia, highlighting a valuable area for future research.
Background/Objective: To explore experiences with diagnostic and treatment delays in systemic lupus erythematosus (SLE), with a focus on barriers and facilitators, as reported by rheumatologists and patients from 4 Latin American Southern Cone countries (Argentina, Chile, Paraguay, and Uruguay). Materials and Methods: A pragmatic qualitative approach was employed, consisting of in-depth interviews with patients and focus groups with rheumatologists and internists. The study was guided by 2 complementary conceptual frameworks: the World Health Organization’s (WHO) right-to-health framework and Levesque’s patient-centered access-to-care model. A convenience sampling strategy was used. Qualitative data were thematically analyzed using ATLAS.ti. Results: A total of 34 patients, most with longstanding disease, and predominant cutaneous, articular, and renal involvement, and 33 physicians from both public and private health care sectors participated in the study. The analysis identified 6 key dimensions influencing timely access to care: accessibility (including beliefs and costs), disease presentation (with nonspecific or mild forms leading to a delay in diagnosis), availability of resources (specialists, diagnostic tools, treatments), acceptability (attitudes of health care providers), quality of care, and affordability. In addition to these barriers, several facilitating factors were identified. These included the presence of trained health care professionals, the availability of treatments through specific national programs, and individual-level resources such as patient education and financial means. Conclusion: Although each country presents distinct health care characteristics, common systemic challenges, such as fragmentation, geographic disparities, and inconsistent institutional support, were evident. This study provides critical insights into the complex interplay of structural and individual-level factors influencing access to care for patients with lupus and highlights key areas for future policy and health care interventions.
