Intuition or Rationality? A Revised Knowledge‐Attitude‐Behaviour Framework in Sustainable Consumer Behaviour

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The paper provides a revised knowledge–attitude–behaviour (KAB) framework to explain sustainable consumption. Drawing on the dual‐process perspective, the study investigates how intuitive and rational cues shape the translation of objective product knowledge into sustainable attitudes and consumption.

Decomposing niche components reveals simultaneous effects of opposite deterministic processes structuring alpine small mammal assembly

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionSpecies distribution in alpine areas is constrained by multiple abiotic and biotic stressors. This leads to discrepant assembly patterns between different locations and study objects as opposite niche-based processes—limiting similarity and ...

Fecundity data Poisson overdispersion tests.

open access: yes, 2015
Results of Poisson overdispersion tests [44] for three measures of hoary marmot fecundity, based on data from 10 hoary marmot social groups in the Ruby Range, Yukon Territory, 1999–2004 and 2007–2009.

Consistency and asymptotic normality of the maximum likelihood estimator in a zero-inflated generalized Poisson regression [PDF]

open access: yes, 2005
Poisson regression models for count variables have been utilized in many applications. However, in many problems overdispersion and zero-inflation occur.

Copula‐based joint modelling of emergency department visits with time‐varying dependence

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

The Ridge-Hurdle Negative Binomial Regression Model: A Novel Solution for Zero-Inflated Counts in the Presence of Multicollinearity

open access: yesStats
Datasets with many zero outcomes are common in real-world studies and often exhibit overdispersion and strong correlations among predictors, creating challenges for standard count models.

Overdispersion Tests in Count-Data Analysis

open access: yes, 2008
Count data are commonly assumed to have a Poisson distribution, especially when there is no diagnostic procedure for checking this assumption. However, count data rarely fit the restrictive assumptions of the Poisson distribution.

SDG Reporting in Spanish Listed Companies: A Longitudinal Industry‐Level Analysis Using Natural Language Processing (2018–2023)

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study analyzes the evolution of Sustainable Development Goal (SDG) disclosure among IBEX 35 companies between 2018 and 2023, combining natural language processing for disclosure measurement with negative binomial generalized linear mixed models incorporating financial and governance controls.

A Semiparametric Approach to Test for the Presence of INAR: Simulations and Empirical Applications

open access: yesMathematics, 2022

Phylogenetic structure of conifers in regional floras in relation to climate and environmental heterogeneity worldwide

open access: yesEcography, EarlyView.
Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...
