On the Relationship Between Differential Item Functioning and Item Difficulty: An Issue of Methods? Item Response Theory Approach to Differential Item Functioning
(SAGE PUBLICATIONS INC, 2012)
The relationship between differential item functioning (DIF) and item difficulty on the SAT is such that more difficult items tended to exhibit DIF in favor of the focal group (usually minority groups). These results were ...
Potential functional and numerical response in a large sized raptor may be mediated by the abundance of an exotic lagomorph
(Elsevier, 2020-04)
Predators relying on a particular prey as their main food resource are especially susceptible to fluctuation in prey availability. When prey abundance decreases they show a functional response by adjusting their diet. After ...
Functional traits, the phylogeny of function, and ecosystem service vulnerability
(Wiley, 2013-09)
People depend on benefits provided by ecological systems. Understanding how these ecosystem services – and the ecosystem properties underpinning them – respond to drivers of change is therefore an urgent priority. We address ...

Multivariate Quantile Impulse Response Functions
(Wiley Blackwell Publishing, Inc, 2019-08)
A reduced form multivariate quantile autoregressive model is developed to study heterogeneity in the effects of macroeconomic shocks. This framework is used for forecasting and for constructing quantile impulse response ...

Sufficients conditions for analysis of extrema in the step-response of the linear control systems
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01)
This note deals whith the problem of extrema which may occur in the step-response of a stable linear system with real zeros and poles. Some simple sufficients conditions and necessary conditions are presented for analyses ...
