Global convergence and uniform bounds of fluctuating prices in a single commodity market model of Bélair and Mackey

Electronic Journal of Qualitative Theory of Differential Equations, 2012
We extend the analysis of the global dynamics for a special class of single commodity market models introduced by Bélair and Mackey. In particular, we determine uniform asymptotic bounds for the fluctuating price, and give sufficient conditions for the ...

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)

Acta Zoologica, EarlyView.
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

IRT‐based response style models and related methodology: Review and commentary

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract We provide a review and commentary on recent methodological research related to item response theory (IRT) modelling of response styles in psychological measurement. Our review describes the different categories of IRT models that have been proposed, their associated assumptions and extensions, and the varying purposes they can serve.

On the global attractor of delay differential equations with unimodal feedback not satisfying the negative Schwarzian derivative condition

Electronic Journal of Qualitative Theory of Differential Equations, 2020
We study the size of the global attractor for a delay differential equation with unimodal feedback. We are interested in extending and complementing a dichotomy result by Liz and Röst, which assumed that the Schwarzian derivative of the nonlinear ...

Exploring the leaky pipeline: Tokenism, status group effects, or self‐selection?

European Management Review, EarlyView.
Abstract In most European universities today, more than 50% of bachelor's degrees are awarded to women, but the corresponding share of full professorships is only about 25%. This phenomenon is called the leaky pipeline. Most explanations refer to gender biases and stereotypes, motherhood, discrimination, and tokenism.
