Phenology, mass accumulation patterns and growing degree days in common bean
Get PDFThe common bean represents approximately half of the global production of leguminous grains. Brazil is the world's largest producer, as it is a primary source of protein in the population's diet. This research aimed to relate the phenological stages of the common bean under greenhouse conditions and establish a connection between mass accumulation patterns and the environment, specifically temperature, by estimating Growing Degree Days (GDD) during two periods with different temperatures throughout the year. Once a week, after seed germination, plants were collected and weighed to quantify fresh and dry mass to determine biomass allocation within the plant. This procedure was carried out until the plant’s growth cycle was completed. The environment was systematically monitored using a thermo-hygrometer. GDD accumulation was estimated for the phenological stages from V0 to R8 during two evaluation periods. Fresh and dry mass accumulation was fitted to logistic models that generated sigmoidal-type curves. It was observed that the bean plants accumulated 803.5 GDD in the first period and 808.6 GDD in the second period, from V0 to R8, with different fresh and dry mass accumulation patterns in various plant organs. This demonstrates the relationship between temperature and the growth and development of the bean plant and can provide important information for selecting the optimal planting time for this significant crop
Experiencia artístico pedagógica en la promoción de la salud mental de la estrategia de movilización social ciudad bienestar de Pasto entre 2013 y 2021
No full textLa presente investigación se plantea con el objetivo de comprender los aprendizajes de las practicas artístico pedagógicas en la promoción de la salud mental derivados de las experiencias de los agentes de la Estrategia de Movilización Social Ciudad Bienestar de Pasto, en el periodo comprendido entre 2013 a 2021. La investigación se enmarcó en el paradigma epistemológico crítico social, utilizando el paradigma metodológico cualitativo, siendo este estudio una sistematización de experiencias. El trabajo se realiza con nueve profesionales líderes de la ECB, resaltando las experiencias en torno a las practicas artístico pedagógicas, estas perspectivas apuntan al arte como proceso transformador, procesos influenciados por la interacción con las dinámicas de articulación institucional y su intención de generar promoción en salud y salud mental desafiando los modelos convencionales de investigación en salud y posicionándose ante realidades constituidas dentro de la estrategia, en lo que respecta al marco teórico se resaltan unas categorías claves como son la salud mental colectiva, la promoción de la salud, la determinación social, la pedagogía emancipadora y las practicas artístico pedagógicas. Los resultados describen en una línea de tiempo la reconstrucción de experiencias de las practicas artístico pedagógicas frente a la promoción de la Salud Mental, igualmente se realizó una reflexión de los aprendizajes derivados de las experiencias de los agentes frente a las practicas artístico pedagógicas y finalmente se desarrollaron recomendaciones a partir de las practicas artístico pedagógicas para la ECB en el marco de la promoción de la Salud Mental
Business cycles in Colombia: stylized facts
Get PDFThe purpose of this article is to examine the economic cycles in Colombia and to empirically corroborate the fulfillment of nine stylized facts documented in the specialized international literature. For this purpose, the retropolated series 1975-2013 and the series 2005:1-2022:4 of the National Administrative Department of Statistics (DANE) were analyzed using the Hodrick-Prescott filter. Thus, the occurrence of four economic cycles is recorded between 1975 and 2013 with an average duration of 9.3 years with an expansionary phase of 5.0 years and a contractionary phase of 5.3 years. Similarly, between 2005:1 and 2022:4 there were three cycles with an average duration of 21.7 quarters, with an expansionary phase of 14.7 quarters and a contractionary phase of 7.0 quarters. It should also be said that the cyclical fluctuations of employment and unemployment are closely related to effective demand and domestic demand in accordance with Keynesian theory; for example, the positive correlation between the real GDP cycle and the implicit GDP deflator cycle suggests that the cycles were not due to shifts in the aggregate production function as the dominant theory stresses, but to shifts in the aggregate demand function
Reengineering in emerging businesses: a consequence of the COVID-19
Get PDFThis research explores the repercussions of COVID-19 on global trade and markets during the first half of 2020. The study examines the economic impact of the pandemic on companies, emphasizing the need to rethink the business or redesign it to ensure its response to the challenges that the quarantine represented, as proposed by reengineering in the second half of the 90s of the 20th century. The main objective of this article is to establish a connection between the principles of reengineering and the resilience of startups during the pandemic, reactivating the use of a tool that was used more than 20 years ago. Therefore, the study explores, from a qualitative methodology —with emphasis on documentary research— the relationship between the appearance of the pandemic and the use of some elements of reengineering that can be observed in emerging companies, finding several connections between them. The results highlight how, through reinvention and resurgence, emerging businesses met the challenges of the new normal by maintaining their operations and providing business continuity
Students' perception of the application of nudges
Get PDFIn this research it was examined how students of two private institutions perceive the nudges. Although the nudge theory has gained considerable popularity in international research, as it is reflected on recent articles in international magazines, it does not count on the recognition or implementation in a local context. In that way, with the developed research, knowledge is generated with regard to the population object of study and it is an important test about the possible implementations of deliberative and non-deliberative nudges in public policies. The methodology used is a quantitative approach, descriptive method, snowball probabilistic sample technique and the test was carried out through chi square to determine gender perception. The results gotten showed that students are receptive to the use of nudge tool in their daily contexts. In conclusion, there is acceptance of the use of deliberative nudges and there is a little distrust of non-deliberative nudges, likewise, it is exposed that nowadays the nudge tool is discussed in top level international universities; nevertheless, in the Latin American context, its formulation is minimal
Pseudoclassical mechanics à la Faddeev–Jackiw
Get PDFIn this study, we propose an extension of the formulation developed by Faddeev and Jackiw to include anticommutative variables in the language of supergeometry, as it could be a cost-effective way to determine the (Z2 graded) Poisson structure of theories describing spin-like degrees of freedom. Specifically, we apply the developed approach to pseudoclassical systems to lately use the standard canonical quantization program to check whether their already known quantum description is recovered
