Gender‐Sensitive Resilience in Kyrgyz Households: Latent Profile and Cross‐Lagged Dynamic Panel Approaches

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Resilience is still conceptualised as gender‐neutral in research and policy discussions. However, a gendered resilience framework suggests that gender roles and intra‐household dynamics are intricately linked with household resilience. This manuscript aims to analyse the effect of gender role attitudes on climate change resilience.

Productivity and Human Disturbance Shape Contrasting Distribution Patterns of Core and Occasional Bird Species in a Subtropical Forest Reserve in Southern China

open access: yesIntegrative Zoology, EarlyView.
Bird diversity hot spots in a recovering subtropical forest do not align with protected area zoning, instead occurring in experimental zones with low‐intensity human activity. This mismatch is driven by contrasting responses: Abundant core species are supported by productivity, while many species of low frequency are attracted to the habitat ...

Residual diagnostics for assessing closed population capture–recapture models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Capture–recapture models provide a statistical framework for estimating demographic parameters from incomplete observation data, where not all individuals in a population are detected during sampling. Assessing the fit of such models is crucial for reliable inference.

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 ...

Heterogeneidade de Variância na Avaliação Genética de Reprodutores da Raça Pardo-Suíça no Brasil

open access: yesRevista Brasileira de Zootecnia, 2002
Informações de 6.842 lactações de 3.274 vacas da raça Pardo-Suíça, filhas de 71 reprodutores, distribuídas em 100 rebanhos, com parições entre 1980 a 1999, foram utilizadas para verificar a existência da heterogeneidade de variância entre rebanhos e o ...

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.
