Abstract (Introduction): The current cultivation of trees is insufficient to cover the national demand for wood, in this way small producers become an alternative solution to this situation, since despite having small areas, in the country there are abundant farms with these conditions; However, the current forest management scheme does not meet adequate standards for the incorporation of these small producers. (Objective): To present an adaptive forest management scheme (AFMS) to the needs of the small farmer, in addition, to demonstrate the institutional availability to change according to expert criteria. (Methodology): 1) the factors that influence the decision to adopt an agricultural or forestry production system were identified; 2) a profile of an ideal productive system that met the interests and preferences of the small producer was made, which was compared with the characteristics of agricultural and forestry production; 3) the proposal of an EMFA adjusted to the preferences and interest of the producer was made, which was also compared with the ideal profile; 4) three proposed change actions were presented to experts, obtaining different degrees of possibility of changes in the EMFA. (Results): The discrepancy of the forest management scheme for the cultivation of trees with the perspective that a small producer has on an ideal production system was evidenced, as well as the substantial improvement that an EMFA would have in the valuation of the small producer and the institutional availability to change the EMFA according to the perspective of the small producers. (Conclusions): The adjustment of the forest management scheme allows a greater adoption of the activity by the small producer, but it was recognized that any proposal that is made would be successful only if forest governance makes it more flexible and allows change.

Resumen (Introducción): El cultivo actual de árboles es insuficiente para cubrir la demanda nacional de madera, de este modo, los pequeños productores se tornan como una alternativa de solución ante esta situación, ya que pese a contar con áreas pequeñas, en el país son abundantes las fincas con estas condiciones; sin embargo, el esquema actual de manejo forestal no cumple con estándares adecuados para la incorporación de estos pequeños productores. (Objetivo): Presentar un esquema de manejo forestal adaptativo (EMFA) a las necesidades del pequeño productor, además de evidenciar la disponibilidad institucional al cambio, según el criterio experto. (Metodología): 1) se identificaron los factores que influyen en la decisión de adopción de un sistema productivo agrícola o forestal; 2) se realizó un perfil de un sistema productivo ideal que cumpliera con los intereses y preferencias del pequeño productor, el cual se confrontó con las características de la producción agrícola y forestal; 3) se efectuó la propuesta de un EMFA ajustado a las preferencias e interés del productor, que fue también confrontada con el perfil ideal; 4) se expusieron tres acciones de cambio propuestas ante expertos, obteniendo diferentes grados de posibilidad de cambios en el EMFA. (Resultados): Se evidenció la discrepancia del esquema de manejo forestal para el cultivo de árboles con la perspectiva que un pequeño productor tiene sobre un sistema de producción ideal, asimismo la mejora sustancial que un EMFA tendría en la valoración del pequeño productor y la disponibilidad institucional al cambio del EMFA, según la perspectiva de los pequeños productores. (Conclusiones): El ajuste del esquema de manejo forestal permite una mayor adopción del cultivo de árboles por parte del pequeño productor, pero se reconoció que cualquier propuesta que se realice lograría ser exitosa si la gobernanza forestal flexibiliza y posibilita el cambio.

RESUMO Este estudo foca no desempenho de vacas para produção de carne, criadas nos pântanos do Paraguai, examinando cinco genótipos bovinos; Brahman, Brangus, Nelore, bem como duas raças locais em risco de extinção. O principal objetivo é identificar e classificar variáveis fenotípicas que incluem variáveis sanguíneas, clínicas, de pelagem e saúde, demonstrando ligação causal com o peso vivo das vacas analisadas. Inicialmente, foram identificadas correlações elevadas entre diferentes variáveis incluídas neste estudo, e, então, utilizando técnicas avançadas de aprendizado de máquina e a aplicação de explicações aditivas de Shapley (SHAP), foi proporcionado um entendimento mais profundo dos fatores fortemente associados à adaptabilidade nestes ambientes, e, portanto, o respectivo desempenho zootécnico. A associação entre o componente genotípico bovino ligado à estação do ano mostrou ser o fator influente mais predominante sobre o peso vivo bovino. Variáveis como comprimento do pelo, hematócrito, fosfatase, fósforo, creatina phosphokinase, creatinina, proteína, cortisol, cálcio e a presença de endoparasitas foram destacadas, demonstrando sua importância hierárquica para a seleção animal.

ABSTRACT This study focuses on the performance of cows for meat production raised in the wetlands of Paraguay, examining five cattle genotypes: Brahman, Brangus, and Nelore, as well as two local breeds at risk of extinction. The main objective is to identify and rank phenotypic variables, including blood, clinical, hair, and health variables, demonstrating causal linkage with the live weight of the cows analyzed. Initially, high correlations were identified between different variables included in this study; then, using advanced Machine learning (ML) techniques and the application of Shapley additive explanations (SHAP), a deeper understanding was provided of the factors strongly associated with adaptability in these environments, and, therefore, the respective zootechnical performance. The association between cattle genotypic components linked with the season of the year proved to be the most influential factor on cattle live weight. Variables such as hair length, hematocrit, phosphatase, phosphorus, creatine phosphokinase, creatinine, protein, cortisol, calcium, and the presence of endoparasites were highlighted, demonstrating their hierarchical importance for animal selection. ML models are effective tools for establishing hierarchies of relevance in complex phenotypic multivariable, which is crucial in breeding programs for different zootechnical species and in special and specific environments like wetlands.

ABSTRACT The cowpea is a legume that is widely grown in the north-east of Brazil, and which has been gaining ground in other regions of the country. The main producer is the state of Ceará, with a large planted-area, albeit low productivity due to a lack of producer technology and adapted cultivars. The aim of this study was to identify and recommend superior genotypes in terms of adaptability and stability under rainfed and irrigated conditions, in addition to genotypes with reduced grain darkening. To this end, six experiments were conducted in different districts of Ceará (Crato, Pentecoste, Crateús, Madalena, Bela Cruz and Limoeiro do Norte) and one laboratory experiment, to evaluate grain darkening. The experimental design of the field trials was of randomised blocks, with 14 genotypes and 4 replications. The analysis of variance showed a significant effect from the genotypes and environments and their interaction, so GGE Biplot analysis was carried out to evaluate adaptability and stability. To evaluate grain darkening, a completely randomised design was used in a simple factorial scheme with six previously selected genotypes and five different storage times (0, 2, 4, 6 and 8 months). There was a significant effect from the genotypes and storage time. Genotype 1 showed the least darkening, and can be recommended for environments to which it is best adapted (Crato and Crateús). Genotype 9 was considered the most stable for grain yield, and can be more broadly recommended for the semi-arid region of the state of Ceará. northeast north east Brazil country plantedarea, plantedarea planted area, area planted-area cultivars conditions darkening end Crato, Crato Pentecoste Crateús Madalena Norte experiment blocks replications interaction 0, 0 (0 2 months. months . months) time Crateús.

ABSTRACT: The study of adaptability, stability, and productivity is essential for selecting and recommending superior genotypes. This fact is particularly the case for the introduction of common bean cultivars in Rio de Janeiro, Brazil, whose production is negligible and does not meet the internal demand. Thus, this study estimated genetic parameters and selection gains and undertake a simultaneous selection for adaptability, stability, and productivity in black bean genotypes via mixed models. The investigation was carried out in three municipalities in the state of Rio de Janeiro during three crop years. The trials were set up in a randomized block design with 11 genotypes and three replications. High mean heritability (81%) and selection accuracy (90%), as well as good selection prospects, were observed. Gains between 1.03 and 9.49% were achieved for grain yield. Simultaneous selection was efficient, indicating two black bean lines (CNFP 15290 and CNFP 15361) as the most productive, adaptable, and stable. As such, these lines have the potential to be released as new black bean cultivars for the state of Rio de Janeiro.

RESUMO: O estudo de adaptabilidade, estabilidade e produtividade é importante para selecionar e recomendar genótipos superiores. Esse fato é particularmente válido para a introdução de cultivares de feijão comum no Rio de Janeiro, Brasil, cuja produção é ínfima e não atende a demanda interna. Assim, este trabalho teve como objetivo estimar parâmetros genéticos e ganhos de seleção e realizar uma seleção simultânea para adaptabilidade, estabilidade e produtividade de genótipos de feijão preto através de modelos mistos. O estudo foi realizado em três municípios do estado do Rio de Janeiro e em três anos agrícolas. Os ensaios foram instalados em delineamento de blocos casualizados com 11 genótipos e três repetições. Observou-se alta herdabilidade média (81%), acurácia seletiva (90%) e boas perspectivas de seleção. Também foram observados ganhos satisfatórios para a característica entre 1,03 e 9,49%. A seleção simultânea foi eficiente e permitiu selecionar duas linhagens de feijão preto CNFP (15290 e 15361) como sendo as mais produtivas, adaptáveis e estáveis e, portanto, têm potencial para serem lançadas como novas cultivares de feijão preto para o estado do Rio de Janeiro.

Abstract Background: Maize landraces show remarkable diversity and environmental adaptability in Mexico. Nevertheless, few studies have explored physiological mechanisms used by different maize landraces to grow and yield in a particular agroecological region. Question: How do three landrace maize populations from contrasting maize races in southeastern Mexico, differ in their responses in terms of growth, chlorophyll fluorescence, and gas exchange? Studied species: Zea mays L. Study site and date: Yucatan, Mexico; 2017. Methods: The field experiment followed a complete randomized block design, with six replicates. Three contrasting maize landraces were evaluated as treatments. Response variables were vegetative traits, dry matter allocation, yield components, and maize physiological responses. Data were analyzed by one-way ANOVA and post hoc Tukey multiple comparison test (P ≤ 0.05). Results: Maize landraces showed differences in cycle length, plant morphology, and yield performance. The long cycle maize landrace Xnuc-naal, had tall plants that accumulated 17 and 21 % more dry matter than Xmejen-naal and Elotillo, respectively. The short-cycle maize landraces Elotillo and Xmejen-naal exhibit superior physiological responses leading to higher grain yields compared to the Xnuc-naal. Conclusions: The landrace Xnuc-naal stood out for its ability in forage production, whereas Elotillo and Xmejen-naal exhibited notable physiological efficiency in grain production in southeastern Mexico.

Resumen Antecedentes: Las razas nativas de maíz muestran una notable diversidad y adaptabilidad en México. Sin embargo, pocos estudios han explorado los mecanismos fisiológicos utilizados por las diferentes razas de maíz para crecer y producir en una región agroecológica en particular. Pregunta: ¿Cómo difieren en sus respuestas en cuanto a crecimiento, fluorescencia de la clorofila e intercambio de gases tres variedades de maíz que provienen de razas contrastantes del sureste de México? Especie estudiada: Zea mays L. Sitio y fecha del estudio: Yucatán, México; 2017. Métodos: El experimento de campo siguió un diseño de bloques completamente aleatorios, con seis repeticiones. Se evaluaron tres variedades nativas de maíz contrastantes como tratamientos. Las variables de respuesta fueron rasgos vegetativos, distribución de materia seca, componentes del rendimiento y respuestas fisiológicas de las variedades de maíz. Los datos fueron analizados mediante ANOVA de una vía y la prueba de comparación múltiple de Tukey (P ≤ 0.05). Resultados: Las variedades locales de maíz mostraron diferencias en la duración del ciclo, morfología de la planta y rendimiento. La variedad tardía Xnuc-naal, tuvo plantas altas que acumularon un 17 y 21 % más materia seca que Xmejen-naal y Elotillo, respectivamente. Las variedades precoces Elotillo y Xmejen-naal exhibieron una respuesta fisiológica superior que llevó a un rendimiento de grano superior al de Xnuc-naal. Conclusiones: La variedad de maíz Xnuc-naal destacó por su capacidad para la producción de forraje, mientras que Elotillo y Xmejen-naal demostraron una eficiencia fisiológica notable en la producción de grano en el sureste de México.

SUMMARY: The rapid advancement of the Internet of Things (IoT) has transformed our lives by connecting objects and creating an intelligent environment that drives automation and massive data collection. IoT has overcome challenges through remote monitoring, robotics, and sensors, with powerful wireless technologies opening up possibilities in various fields, including anatomical techniques. The objective of this study is to demonstrate the feasibility and benefits of integrating IoT technology into the body maceration process by developing a low-cost, accessible, automated maceration control device compatible with theArduino IDE programming environment. Using an open-source NodeMCU system based on the ESP-12E chip, which employs the LUA programming language and is compatible with Arduino IDE, we incorporated a microSD card reader module for data storage, a digital temperature sensor (DS18B20), a clock module (DS3231), a magnetic stirrer, and an aquarium heater controlled by a digital thermostat with relay (W1209). To validate the device, we conducted maceration tests on C57BL mice, comparing two groups: Control (n=5; weight=17g) subjected to maceration in 4 liters of water at 10°C without agitation; Experimental (n=5; weight=17g) exposed to maceration in 4 liters of water at 35°C, with agitation at 1500 r/min and water flow renewal at a rate of 900 ml/h. Specimens were evaluated for their degree of maceration, cleaned, weighed, and photographed. The maceration time for the control and experi- mental groups was 730 hours and 60 hours, respectively. In the experimental group, no foul odors, damage, or bone demineralization were detected. The device cost was 60 USD, and programming through the Arduino IDE environment was straightforward. The focus on hardware contributed to accessibility and time savings. The system operated with a conventional power supply and required a water supply, making it adaptable to various configurations with greater capacity. Under this configuration, we effectively controlled the variables (temperature, agitation, and water flow). The NodeMCU-based bone maceration system improved the performance and adaptability of existing systems and increased accessibility by reducing costs, complexity, and foul odors.

RESUMEN: El rápido avance del Internet de las Cosas (IoT) ha transformado nuestras vidas al conectar objetos y crear un entorno inteligente que impulsa la automatización y la recolección masiva de datos. El IoT ha superado desafíos a través del monitoreo remoto, la robótica y los sensores, con tecnologías inalámbricas potentes que abren posibilidades en diversos campos, incluidas la anatomía y las técnicas anatómicas. El objetivo de este estudio fue demostrar la viabilidad y los beneficios de integrar la tecnología IoT en el proceso de maceración cadavérica mediante el desarrollo de un dispositivo de control de maceración automatizado, accesible y de bajo costo, compatible con el entorno de programación Arduino IDE. Usando un sistema NodeMCU de código abierto basado en el chip ESP-12E, que emplea el lenguaje de programación LUA y es compatible con Arduino IDE, incorporamos un módulo lector de tarjetas microSD para el almacenamiento de datos, un sensor de temperatura digital (DS18B20), un módulo de reloj (DS3231), un agitador magnético y un calentador de acuario controlado por un termostato digital con relé (W1209). Para validar el dispositivo, realizamos pruebas de maceración en ratones C57BL, comparando dos grupos: control (n=5; peso=17g) sometido a maceración en 4 litros de agua a 10°C sin agitación; experimental (n=5; peso=17g) expuesto a maceración en 4 litros de agua a 35°C, con agitación a 1500 r/min y renovación del flujo de agua a una velocidad de 900 ml/h. Los especímenes fueron evaluados según su grado de maceración, limpiados, pesados y fotografiados. El tiempo de maceración para los grupos control y experimental fue de 730 horas y 60 horas, respectivamente. En el grupo experimental no se detectaron malos olores, daños ni desmineralización de los huesos. El costo del dispositivo fue de 60 USD y la programación a través del entorno Arduino IDE fue sencilla. El enfoque en el hardware contribuyó a la accesibilidad y al ahorro de tiempo. El sistema operaba con una fuente de alimentación convencional y requería un suministro de agua, lo que lo hace adaptable a diversas configuraciones con mayor capacidad. Bajo esta configuración, controlamos eficazmente las variables (temperatura, agitación y flujo de agua). El sistema de maceración ósea basado en NodeMCU mejoró el rendimiento y la adaptabilidad de los sistemas existentes, y aumentó la accesibilidad al reducir los costos, la complejidad y los malos olores.

Resumen Antecedentes: En la reforestación se recomiendan plantas nativas y en fuentes de la regeneración natural.

Abstract Background: Plant species used for reforestation purposes are idoneous if native, and also if they are present in regeneration sources. High germination percentages under different light conditions and a broad phenological pattern enhance adaptability to environmental heterogeneity. Preference for species responsive to mycorrhizal inoculation is recommended. Questions: Is Solanum pubigerum a widespread species in temperate forests of central Mexico?, under which light conditions germination will be the highest?, how abundant is it in natural regeneration sources?, does inoculation with mycorrhizal fungi benefit its germination and growth? Studied species / data description / Mathematical model: Solanum pubigerum/distribution in central Mexico forests, germination and viability percentages, reproductive phenology, growth dependence on AM fungi/ Kruskal-Wallis test, synchrony, Spearman correlations, ANOVA. Study site and dates: Abies religiosa forest, Mexico City. August 2019 - July 2020. Methods: Seeds of S. pubigerum were exposed to different light qualities, their viability was monitored for two years. Its presence in natural regeneration sources was registered. Reproductive phenology was recorded, and seedlings were inoculated with arbuscular mycorrhizal fungi to assess their growth. Results: Highest seed germination occurred under white light conditions, with sustained viability after two years. The species was found in the seed bank across seasons, less abundantly in seed rain during the dry season. It exhibited extensive flowering and fruiting patterns. Mycorrhiza inoculation significantly boosted seed germination and growth. Conclusions: Solanum pubigerum is suitable for reforestation in central Mexico forests due to its high germination percentages and mycorrhizal responsiveness.

Abstract Background: Periods of drought in the Sonoran Desert increase interest in crops with a smaller water footprint. Stenocereus thurberi is an alternative, including economic benefits for the residents. Hypothesis: Vegetative propagation of Stenocereus thurberi stems with differentiated floral areoles for productive purposes will demonstrate high survival, considering seasonal patterns, metabolic activity, and CO2 assimilation, reflecting the adaptability, resistance, and productivity of the species. Study species: Stenocereus thurberi. Study site and dates: Hermosillo, Sonora, Mexico; 2014. Methods: Survival of vegetative propagated stems, metabolic heat production (CM) of reproductive areoles, integrated daily light interception (LDI), and instantaneous CO2 assimilation were evaluated. Results: The vegetatively transplanted stems showed a survival of 100 %, an annual vegetative growth of 9.3 ± 0.6 cm, and a production of 2.0 ± 0.8 fruits per stem. The highest LDI amount was recorded in May (27.2 mol m-2 d-1) and the west side (23.4 mol m-2 d-1). The reproductive areoles showed the highest CM production in May with 2 µW mg-1 dry weight (ps) and the highest energy expenditure with 1,759.6 kJ mol-1. The lowest respiratory rate of the areolas occurred in June with 0.003 nmol s-1 mg-1 dw. The rates of greatest CO2 assimilation occurred in March, September, and October with 6.3, 3.8, and 6.5 µmol CO2 m-2 s-1, respectively. Conclusions: It is possible to reproduce pitayas vegetatively from stems with differentiated reproductive areoles for productive purposes, promoting an efficient cultivation with low water consumption and economic potential.

Hierdie sewe-jaar longitudinale opvoedingstudie evalueer drie akademiese afleweringsmodusse vir deeltydse MBA-studente in hul Bemarkingsbestuursmodule, naamlik vol kontak (20172019), vol aanlyn tydens COVID-19 se harde inperking (2020-2021 en die daaropvolgende gemengde modus (2022-2023). Die studie het ten doel om te bepaal of die afleweringsmodus studente se akademiese prestasie beduidend beïnvloed. Die eenrigting-variansie-analise (EVA) het beduidende verskille tussen die afleweringsmodusse vir individuele opdragte (normatiewe assessering) en groepgevallestudies (summatiewe assessering) geïdentifiseer. Daar was ook betekenisvolle verskille tussen die akademiese prestasie ten opsigte van die finale saamgestelde portefeulje van kennis (wat as eksamen dien). Hierdie portefeulje bestaan uit 'n prakties-toegepaste bemarkingsplan. Die post-hoc toetse het getoon dat studente aansienlik beter gevaar het tydens die gemengde afleweringsmodus in individuele opdragte, terwyl die volledige aanlyn modus laer punte vir die groepgevallestudies gehad het. Beide die gemengde en volledige kontakmodusse het beduidende opeenvolgende verbetering vir die groepgevallestudies getoon, wat in elke gevallestudie verbetering getoon het namate die semester gevorder het. Dit verskil van volledige aanlyn onderrig. Die gemengde modus het ook aansienlik beter gevaar in die eksamen- en finale modulepunte en het selfs beter gevaar as volkontakklasse.

The COVID-19 pandemic significantly transformed the tertiary education landscape. Traditional contact universities were forced abruptly to adopt a full-distance education mode, a situation neither the students nor lecturers were prepared for. Many lectures and teaching activities were developed on the fly as universities struggled to roll out the needed support in double-time for lecturers and students. This new normal for education required integrating technology, advanced communication software, revised assessment techniques, and recognising the need for flexible and adaptable approaches to teaching and learning. Students also evolved and gained technological proficiency, adaptability, time management, soft skills, social media proficiency, and an awareness of health and well-being. Albeit uncertain in redefining the new normal, universities continue to provide quality education. However, exactly how university education should be delivered to a new breed of students in a new business environment is a challenge. This is even more so in the case of executive MBA students. After the hard lockdown and restrictions were lifted on 21 September 2020, the North-West University Business School started to explore other modes of academic content delivery. Reinstating a full contact delivery mode was not an option because of remaining restrictions. High technological investment, online-educated lecturers and students, and benefits and developments during online learning now form a new normal for the Business School. Which teaching method, or rather, which mode of delivery, is the most relevant and adequate? Should the MBA lectures return to the historic full-contact delivery mode, stick with the newly established full online mode, or attempt to integrate the benefits of both into a hybrid mode of delivering business education to a new breed of technology-savvy students? This study, therefore, examines the academic performance of the different delivery modes by comparing data of Executive MBA Marketing management students at the NWU Business School in South Africa. The study examines the academic performance of these students from 2017 up to 2023. The panel database consists of Executive MBA students'marks for the module in Marketing Management from 2017 up to 2023. The database contains marks for individual assignments, groupwork case studies, final individual- and groupwork marks, exam marks and the final module mark. The final assessment is a portfolio of evidence comprising a detailed marketing plan for a product, service, or organisation of choice. The mode of delivery served as the dependent variable, while the independent variables comprised the marks for each assignment (groupwork, individual and portfolio of evidence). Three delivery modes were compared, namely full-contact (2017-2019), full-online (2020-2021), and the post-pandemic hybrid mode currently in effect (2022-2023). The data comprised 630 cases. However, the analysis of variance (ANOVA) used 532 cases to compare the different groupwork assignments (230 full-contact students, 159 full-online students, and 143 hybrid students). Cronbach's alpha coefficient measured the data's reliability, and one-way ANOVA determined significant differences (p<.05) between the academic performance of the three delivery modes. The analysis confirmed that significant differences exist between the modes of delivery for individual assignments, group case studies and exams (p<.05). The Tukey ab post-hoc tests showed that students performed significantly better during the hybrid delivery mode in individual assignments (69.2%) than full contact (63.8%). Regarding the individual assignment, the full online (63.8%) and full contact (63.7%) delivery modes perform significantly worse than the hybrid (69.2%) delivery mode. Regarding the first group case study (Group Assignment 1), full online performs (67.3%) significantly worse than hybrid (71.1%) and full contact (73.6%) delivery modes. There is no significant difference between the hybrid and full contact delivery modes. In the second, third, and fourth group case studies (Group Assignments 2, 3 & 4), the hybrid delivery mode (82.37%, 75.4%, 82.7%) outperforms the full contact (75.4, 80.1%, 86.6%) and full-online (71.4%, 71.4%, 67.8%) modes. The hybrid delivery mode, therefore, proves to be more conducive towards academic performance in group work. Finally, in considering the final module mark, the hybrid delivery mode (71.0%) is significantly higher than the other two delivery modes. However, there is no significant difference between full online (67.5%) and full-contact (67.2%) delivery modes regarding the final module mark. Nevertheless, it is noteworthy that the better performance in the final module marks is a function of the groupwork where the students analysed case studies together. There are no significant differences in the exam marks between the delivery modes, so better academic performance in the hybrid mode of delivery where groupwork is concerned culminates in the better module mark. Based on the findings, it is evident that the hybrid mode of delivery results in the best academic performance. This observation is based on three reasons, namely 1) students performed better in both the normative and summative assessments during hybrid tuition; 2) there is continuous progressive learning throughout the semester regarding the group case studies (summative assessment). They learn to improve and hone their skills to analyse better and apply business solutions to real-life problems experienced by organisations. This is based on students' improving marks in the group case studies as they become more proficient in analysing and answering the applied case studies because they learn from each case study; and 3) the students perform better academically in their normative assessments and earn higher final module marks (partially due to reason 2). It is concluded that the hybrid delivery mode facilitates the academic performance of post-pandemic executive MBA Marketing management students. JEL KODES: I23, I21, M30

Abstract A comparison is established between the traditional design of the linear economy and that of a circular economy through the proposal of heuristic dynamic models based on non-linear systems of ordinary differential equations. It was found that, for critical values of the control parameter, natural resources, through an Andronov-Hopf bifurcation, the circular economy model self-organizes out of thermodynamic equilibrium, and exhibits high complexity, robustness, resilience and adaptability, which was verified by evaluating the Shannon entropy of their trajectories. Finally, it was shown, through an ansatz, that the circular economy model shows greater efficiency compared to the traditional linear model.

Resumen Se establece una comparación entre el diseño tradicional de la economía lineal y el de una economía circular a través de la propuesta de modelos dinámicos heurísticos basados en sistemas no lineales de ecuaciones diferenciales ordinarias. Se encontró que, para valores críticos del parámetro de control, los recursos naturales, a través de una bifurcación de Andronov-Hopf, el modelo de economía circular se autorganiza fuera del equilibrio termodinámico, y exhibe una alta complejidad, robustez, resiliencia y adaptabilidad, lo cual se verificó a través de evaluar la entropía de Shannon de sus trayectorias. Finalmente, se mostró por medio de un ansatz, que el modelo de economía circular muestra una mayor eficiencia en comparación con el modelo tradicional lineal.

ABSTRACT Research on genetic improvement for the cultivation of lulo (Solanum quitoense Lam.) in Colombia is limited. Specifically, research related to genotype-by-environment interaction (GEI) and stability in agronomic traits is scarce. This study aimed to identify superior genotypes by evaluating GEI and the stability of fruit weight (FW), ascorbic acid (AA), and yield among 10 half-sib families (HSF). Four trials were established at San Pedro de Cartago, Arboleda, Tangua and La Union of the department of Nariño (Colombia), using the randomized complete block design with four repetitions. To analyze GEI, the additive main effects and multiplicative interaction (AMMI) model and some AMMI stability parameters were used. In Tangua, HSF7 and the control exhibited specific adaptation with yields of 12.82 and 13.41 t ha-1, respectively, and FW greater than 100 g. In Arboleda, HSF29 obtained the highest yield (16.14 t ha-1) with an FW of 100.53 g. HSF4, HSF28 and HSF49 reached yields above 9.0 t ha-1 and a FW greater than 100 g, indicating their stability and suitability for any of the environments evaluated. HSF25 in AA and HSF29 in yield presented specific adaptation in Arboleda. Stable families across environments with good yield were HSF4, HSF28, and HSF49, with HSF4 and HSF28 showing higher values in two of the three traits, and HSF49 excelling in all three variables. These families can be used in plant breeding programs as parents or distributed to farmers as improved varieties.

RESUMEN La investigación sobre mejoramiento genético para el cultivo de lulo (Solanum quitoense Lam.) en Colombia es limitada. Especificamente, la investigación relacionada con la interacción genotipo-ambiente (IGA) y la estabilidad en caracteres agronómicos es escasa. Este estudio tuvo como objetivo identificar genotipos sobresalientes mediante la evaluación de la IGA y la estabilidad del peso del fruto (PF), ácido ascórbico (AA) y rendimiento de 10 familias de medio hermanos (FMH). Se establecieron cuatro ensayos en San Pedro de Cartago, Arboleda, Tangua y La Unión del departamento de Nariño (Colombia), utilizando el diseño de bloques completos al azar con cuatro repeticiones. Para analizar el IGA se utilizó el modelo aditivo de efectos principales e interacción multiplicativa (AMMI) y algunos parámetros de estabilidad AMMI. En Tangua, FMH7 y el control presentaron adaptación específica con rendimientos de 12,82 y 13,41 t ha-1, respectivamente y PF mayor a 100 g. En Arboleda, la FMH29 obtuvo el mayor rendimiento (16,14 t ha-1) con un PF de 100,53 g. FMH4, FMH28 y FMH49 alcanzaron rendimientos superiores a 9,0 t ha-1 y un PF mayor a 100 g, lo que indica su estabilidad e idoneidad para cualquiera de los ambientes evaluados. FMH25 en AA y FMH29 en rendimiento presentaron adaptación específica en Arboleda. Las familias estables en ambientes con buen rendimiento fueron FMH4, FMH28 y FMH49, donde FMH4 y FMH28 mostraron valores superiores en dos de los tres caracteres, y FMH49 destacó en las tres variables. Estas familias pueden utilizarse en programas de fitomejoramiento como parentales o entregarse a los agricultores como variedades mejoradas.

Resumen: Durante la construcción, los recursos no controlados impactan el desempeño del proyecto. La Gestión del Valor Ganado (GVG) es un método ampliamente utilizado para la gestión de proyectos basado en el control de tiempos y costos. Los avances en las Tecnologías de la Información (TI) brindan opciones para mejorar el método GVG. El GVG es un método a nivel de proyecto que excluye detallar el comportamiento de los parámetros del proyecto a nivel de operaciones de construcción, se manejan en términos económicos agregados a lo largo del tiempo. Por lo tanto, este trabajo estudia la mejora del GVG utilizando TI para expresar el manejo de variables operativas. Este artículo utiliza un proyecto de construcción de carreteras como caso de estudio, para evaluar tres enfoques (es decir, Red Bayesiana (RB), Red Neuronal Artificial (RNA) y EVM-RNA Híbrida) como opciones de mejora para el método GVG. Se encontró que la RNA proporciona la mejor mejora de los resultados del GVG. El uso de la RNA y los parámetros del proyecto mejora el manejo del GVG. Al tener una mayor efectividad en los pronósticos, se espera que mejore la calidad y disponibilidad de los datos para la toma de decisiones, una condición que a su vez puede mejorar la agilidad y adaptabilidad de los resultados del proyecto tal como está construido. El modelo EVM-ANN utiliza parámetros que influyen en la finalización de la implementación del proyecto, lo que facilita la evaluación del desempeño del tiempo del proyecto en función de diversas condiciones en el campo para que el proyecto pueda obtener la mejor estrategia para garantizar su finalización a tiempo.

Abstract: During construction, uncontrolled resources impact project performance. Earned Value Management (EVM) is a widespread method used for project management based on time and cost control. Advances in Information Technology (IT) provide options to improve the EVM method. The EVM is a project-level method that excludes detailing the behavior of project parameters at the level of construction operations, they are handled in aggregated economic terms over time. Thus, this work studies the improvement of EVM using IT to express the handling of operational variables. This article uses a road construction project as a case study, to evaluate three approaches (i.e., Bayesian Network (BN), Artificial Neural Network (ANN), and Hybrid EVM-ANN) as improvement options for the EVM method. It was found that the ANN provides the best improvement of EVM results. The use of ANN and project parameters improves the handling of EVM. By mayor forecast effectiveness, is expected to improve the quality and availability of data for decision making, a condition which in turn may improve agility and adaptability of the project as-built outcomes. The model EVM-ANN uses parameters that influence project implementation completion, making it easier to assess project time performance based on various conditions in the field so that the project can obtain the best strategy to ensure project completion on time.
