Acceso Abierto A Decision support system for evaluation of the knowledge sharing crossing boundaries in agri-food value chains(2019) Boshkoska, Biljana Mileva; Liu, Shaofeng; Zhao, Guoqing; Fernández, Alejandro; Gamboa, Susana; del Pino, Mariana; Zarate, Pascale; Hernandez, Jorge; Chen, HuilanAn agri-food value chain (VC) represents a set of activities aimed at delivering highly valuable products to the market. Due to the diversity of actors in the agri-food VCs ́ accumulated knowledge is typically situated within the boundaries of each entity of the VC. Hence, the question is how to improve knowledge sharing in agri-food VC, or more specifically how can knowledge flow and mobilize among different actors in the VC. To answer this question, we present a decision support system (DSS) for evaluation of knowledge sharing crossing boundaries in agri-food VC. The proposed DSS is developed through two phases: (i) identification of the most common knowledge boundaries by using machine learning and ontology technologies; (ii) transformation of the obtained ontology into a DSS for the evaluation of existing knowledge boundaries. In particular, the developed DSS helps in identifying, evaluating and providing directions for improvement of the knowledge sharing crossing boundaries in agri-food VC. We apply the DSS to evaluate three real VCs: a tomato VC in Argentina, a Chinese leaf VC in China and a brassica VC in the UK. The comparative analysis across the three varied case studies and their evaluation with the proposed DSS lead to more insights into knowledge-based decisions that a particular VC needs to address to improve its knowledge flow, in particular, to obtain insights in the transparency and interoperability of data and knowledge crossing boundaries in agri-food VCs. - Artículo
Acceso Abierto Design thinking and compliance as drivers for decision support system adoption in agriculture(2023) Baumont De Oliveira, Francis J.; Fernández, Alejandro; Hernández, Jorge E.; del Pino, MarianaTo respond to increasing demands for good agricultural practices (GAP) and food safety, governments globally are introducing stringent regulations to govern agricultural compliance that affect production, storage, and sales activities. New legislation in Argentina to enforce GAP is an opportunity to test compliance as an incentive to adopt technological solutions. This research aims to determine whether compliance software is an effective gateway to shift farmers’ decision-making strategies from intuition-based to evidence-based, improving agricultural productivity through technology. Integrating technology can be a significant hurdle for farms but is also a steppingstone towards more reliable processes. To address this, the authors prototype a decision support system (DSS) for greenhouse farmers in La Plata, Argentina, to help farmers keep traceable records of their crops and treatments to reduce compliance risk. The project incorporates lessons learned from previous DSS projects and utilises design-thinking strategies to involve the end-user in the development. - Documento de conferencia
Acceso Abierto A Gateway for Technology Adoption in Agriculture: a Design-Thinking Approach for a Compliance Decision Support System(2020) Baumont de Oliveira, Francis; Marconi, Andrés; del Pino, Mariana; Fernández, Alejandro; Hernández, Jorge E.Globally, consumers are becoming more conscious of unsustainable farming practices. The appetite for safely produced, compliant and pesticide free crops is increasing. In response to these demands, the Argentinian government has issued new regulation to govern the application of <em>good agricultural practices </em>affecting production, storage and selling activities. This legislation is an opportunity to incentivise farm owners to adopt technology for recording mandatory information which has previously proven difficult. This project aims to test whether compliance software is an effective gateway for shifting farmers decision-making to technology, and from intuition-based to evidence-based, improving agricultural productivity. Understanding and integrating technology into their existing practices a substantial challenge for many farms. Consequently, the authors prototype a decision support system (DSS) for greenhouse farmers in Argentina that can track traceability of batches of crop and their treatments to reduce compliance risk. Incorporating lessons learned from previous DSS projects, the authors utilise design-thinking strategies to include end-users in the development of the system. Through such a tool, the authors can trial innovative features to test receptiveness of farm owners to utilise information technology solutions for decision-making, and identify barriers to data collection and technology adoption - Artículo
Acceso Abierto Referencias argentinas para la evaluación de proporciones corporales desde el nacimiento hasta los 17 años(Sociedad Argentina de Pediatría, 2017) del Pino, Mariana; Orden, Alicia; Arenas, María; Fano, VirginiaIntroducción. La alteración de las proporciones corporales puede ser indicativa de enfermedad esquelética, por lo cual su detección resulta de gran utilidad clínica. Objetivos. Estimar los centilos de los índices perímetro cefálico/estatura (PC/E) y estatura sentada/estatura (ES/E), y evaluar su utilidad diagnóstica en un grupo de niños con displasia esquelética. Métodos. Los centilos 3, 10, 25, 50, 75, 90 y 97 de ES/E y PC/E fueron estimados por el método LMS, que utiliza la transformación Box-Cox para normalizar la distribución de los datos a cada edad. Se aplicaron los tests Q-Q plot para evaluar la normalidad de los residuos y el Q test para evaluar la bondad de ajuste. Resultados. La muestra incluyó 4818 niñas y 4803 niños sanos de 0 a 17 años de edad. La mediana del índice ES/E para la edad cayó desde valores de 0,67 al nacer hasta 0,57 a los 4 años. A los 12 años, alcanzó valores de 0,52 y 0,53 para varones y mujeres, respectivamente, y se mantuvo así hasta los 17 años de edad. La mediana del índice PC/E cayó desde 0,45 a los 6 años hasta 0,34 a los 17 años de edad en ambos sexos. Los puntajes Z del ES/E en 20 niños con diagnóstico de hipocondroplasia mostraron mejor la desproporción corporal que la utilización del índice ES/E no ajustado por edad. Conclusiones. Los centilos estimados de PC/E y ES/E muestran que, en el período prepuberal, ocurren los mayores cambios en las proporciones corporales. Estas referencias facilitan una detección más temprana de desproporción corporal en niños con displasia esquelética.
