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 ...

Assessing the impact of preventative measures to limit the spread of Toxoplasma gondii in wild carnivores of Madagascar. [PDF]

Conserv Biol
Abstract Novel multihost pathogens can threaten endangered wildlife species, as well as humans and domestic animals. The zoonotic protozoan parasite Toxoplasma gondii is transmitted by members of Felidae and can infect a large number of animal species, including humans.

Not all data are equal: Influence of data type and amount in spatial conservation prioritisation

Methods in Ecology and Evolution, Volume 9, Issue 11, Page 2249-2261, November 2018., 2018
Abstract Decisions about land use significantly influence biodiversity globally. The field of spatial conservation prioritisation explores allocation of conservation effort, including for reserve network expansion, targeting habitat restoration, or minimising ecological impacts of development.

Bounding the Dynamics of a Chaotic‐Cancer Mathematical Model

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
The complexity of cancer has motivated the development of different approaches to understand the dynamics of this large group of diseases. One that may allow us to better comprehend the behavior of cancer cells, in both short‐ and long‐term, is mathematical modelling through ordinary differential equations.

Contribution of microcosm experiments to conservation science

Conservation Biology, Volume 40, Issue 1, February 2026.
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.

Modelo Matemático Sazonal para Malária

Trends in Computational and Applied Mathematics, 2006
Na Amazônia, onde se concentram 99% dos casos de malária no Brasil, ocorre uma variação nos índices de incidência da malária no decorrer do ano, a qual está relacionada com as condições climáticas que afetam o desenvolvimento do vetor.
