Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

open access: yesAnimal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Bayesian inference for dynamic Q matrices and attribute trajectories in hidden Markov diagnostic classification models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

Composite marginal likelihood estimation of higher‐order diagnostic classification models under high dimensionality

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...

Review of cognitive diagnostic models (CDMs): Recent methodological advancements for addressing practical challenges

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Cognitive diagnostic models (CDMs) have become essential tools for providing fine‐grained information about individuals' mastery of cognitive skills. While prior reviews have emphasized statistical foundations and deep learning‐based developments, this article focuses on recent methodological innovations designed to address persistent ...

Pest‐preservation paradox among insects

open access: yesConservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Sazonalidade do teor de proteína e outros componentes do leite e sua relação com programa de pagamento por qualidade Seasonability of protein and others milk components related with quality payment program

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
Avaliou-se o efeito da variação da qualidade do leite mediante acompanhamento de amostras provenientes de tanques refrigeradores. As 2.970 amostras foram obtidas de outubro/2005 a setembro/2006. Foram realizadas análises de composição, contagem de células somáticas (CCS) e contagem bacteriana total.
