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 ...

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.

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

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.

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 ...

Un modelo matemático para controlar el chikungunya [PDF]
, 2020 La alianza entre las matemáticas y la medicina comenzó en el siglo XVIII con los aportes que hizo el matemático Daniel Bernoulli al estudio de la viruela, cuando formuló un modelo matemático que intentaba explicar la propagación de esta enfermedad.

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