Modelos matemáticos en un problema de epidemias

Modelling in Science Education and Learning, 2016
La introducción de conceptos matemáticos a través del desarrollo y estudio de modelos ha sido tratado en numerosos trabajos. La introducción de los modelos suele hacerse básicamente desde el discurso del professor y el trabajo del alumno suele reducirse ...

Contribution of microcosm experiments to conservation science. [PDF]

Conserv Biol
Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

Administrative burden in digital public service delivery: The social infrastructure of library programs for e‐inclusion

Review of Policy Research, Volume 40, Issue 5, Page 626-645, September 2023., 2023
Abstract In their efforts to digitize public service delivery, countries increasingly use algorithms based on mathematical models, data and/or a combination of different administrative datasets to issue decisions, but recent studies point towards challenges around citizens' understanding, accessing, and filing objections to such automated decisions ...

Estimation of additive genetic variance when there are gene–environment correlations: Pitfalls, solutions and unexplored questions

Methods in Ecology and Evolution, Volume 14, Issue 5, Page 1245-1258, May 2023., 2023
Abstract Estimating the genetic variation underpinning a trait is crucial to understanding and predicting its evolution. A key statistical tool to estimate this variation is the animal model. Typically, the environment is modelled as an external variable independent of the organism, affecting the focal phenotypic trait via phenotypic plasticity.

Using ORRT Models for Mean Estimation under Nonresponse and Measurement Errors in Stratified Successive Sampling

Journal of Probability and Statistics, Volume 2023, Issue 1, 2023., 2023
In the context of a sample survey, the collection of information on a sensitive variable is difficult, which may cause nonresponse and measurement errors. Due to this, the estimates can be biased and the variation may increase. To overcome this difficulty, we propose an estimator for the estimation of a sensitive variable by using auxiliary information

Overall dynamic body acceleration measures activity differently on large versus small aquatic animals

Methods in Ecology and Evolution, Volume 13, Issue 2, Page 447-458, February 2022., 2022
Abstract Acceleration‐based proxies for activity and energy expenditure are widely used in bio‐logging studies of animal movement and locomotion to explore biomechanical strategies, energetic costs of behaviour, habitat use and the impact of anthropogenic disturbance.

Models to Predict the Number of Infected Cases and Deaths from COVID‐19 in Chile and Its Most Affected Regions

Discrete Dynamics in Nature and Society, Volume 2022, Issue 1, 2022., 2022
This paper designs and implements a methodology to model the evolution of the COVID‐19 pandemic, produced by the SARS‐CoV‐2 virus, in what was called the first wave in Chile, which lasted from March 2 to 31 October 2020. The models are based on sigmoidal growth curves and can be used to predict the number of daily infections and deaths in future days ...
