Anchor selection strategies for DIF analysis: Review, assessment, and new approaches [PDF]

open access: yes, 2013
Differential item functioning (DIF) indicates the violation of the invariance assumption for instance in models based on item response theory (IRT). For item-wise DIF analysis using IRT, a common metric for the item parameters of the groups that are to ...

Pooling information across sites and years to estimate bat fatalities at wind farms

open access: yesThe Journal of Wildlife Management, EarlyView.
We compared complete pooling (CP), no pooling (NP), and partial pooling (PP) approaches for estimating detection probabilities and hence bat fatalities at wind farms. Partial pooling integrates information across sites and years, improving precision with sparse data while preserving site‐level variation.

Rasch mxture models for DIF detection: A comparison of old and new score specifications [PDF]

open access: yes, 2013
Rasch mixture models can be a useful tool when checking the assumption of measurement invariance for a single Rasch model. They provide advantages compared to manifest DIF tests when the DIF groups are only weakly correlated with the manifest covariates ...

Dynamical arrest of ultracold lattice fermions [PDF]

open access: yes, 2013
We theoretically investigate the thermodynamics of an interacting inhomogeneous two-component Fermi gas in an optical lattice. Motivated by a recent experiment by L.

Thresholds for minimum clinically important difference, minimal important change and patient acceptable symptom state for the ACL‐RSI and the K‐SES in patients after anterior cruciate ligament reconstruction

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The aim of this study was to calculate and provide Patient Acceptable Symptom State (PASS) thresholds, Minimum Clinically Important Difference (MCID), and Minimal Important Change (MIC) values for the ACL‐Return to Sport after Injury (ACL‐RSI) scale and the Knee Self‐Efficacy Scale (K‐SES) in patients treated with ACL reconstruction ...

Dependent Dirichlet Process Rating Model (DDP-RM) [PDF]

open access: yes, 2013
Typical IRT rating-scale models assume that the rating category threshold parameters are the same over examinees. However, it can be argued that many rating data sets violate this assumption. To address this practical psychometric problem, we introduce a

Item Response Theory Analysis of the Classroom Level Adversity Scale

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT The Classroom Level Adversity Scale (CLA) captures teachers' perceptions of the overall needs and challenges present in their classrooms. It reflects a collective classroom characteristic based on teacher report, providing insight into the degree of ecological risk teachers perceive when working with their students.

Slow Thermalization Between a Lattice and Free Bose Gas

open access: yes, 2013
Using a 3D spin-dependent optical lattice, we study thermalization and energy exchange between two ultracold Bose gases, one of which is bound to the lattice and another that is free from the lattice potential.

Beyond Universal Models: Contextual Pathways Linking Student Psychological and Social Well‐Being to English Learning in Indonesia's General and Islamic Schools

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT Differences in school culture and context can shape how student well‐being influences learning outcomes. This study addresses this gap by examining the relationships between psychological and social well‐being domains and English learning outcomes across Indonesian general and Islamic schools.

Anchor methods for DIF detection: A comparison of the iterative forward, backward, constant and all-other anchor class [PDF]

open access: yes, 2013
In the analysis of differential item functioning (DIF) using item response theory (IRT), a common metric is necessary to compare item parameters between groups of test-takers.
