Validation of a mobility item bank for older patients in primary care
Health and Quality of Life Outcomes, 2012 Background To develop and validate an item bank to measure mobility in older people in primary care and to analyse differential item functioning (DIF) and differential bundle functioning (DBF) by sex.

Eğitimde ve Psikolojide Ölçme ve Değerlendirme Dergisi, 2022 A differential bundle function (DBF) is a situation in which examinees who are of the same ability but are from different groups are required to answer groups of items differently. DBF undermines the validity of the instrument if inadequately considered.

An Analysis of Differential Bundle Functioning in Multidimensional Tests Using the SIBTEST Procedure
International Journal of Assessment Tools in Education, 2022 This study aims to analyze the differential bundle functioning in multi-dimensional tests with a specific purpose to detect this effect through differentiating the location of the item with DIF in the test, the correlation between the dimensions, the ...

Hermitian-Einstein metrics on stable vector bundles over compact Kähler orbifolds [PDF]
arXiv, 2022 For a holomorphic vector bundle over a compact K\"ahler orbifold, the slope stability of the bundle is shown to be equivalent to the existence of a Hermitian-Einstein metric or to the properness of a certain functional introduced by Donaldson.

Classification of extensions of principal bundles and transitive Lie groupoids with prescribed kernel and cokernel [PDF]
J. Math. Phys., 45(10):3095-4012, 2004, 2004 The equivalence of principal bundles with transitive Lie groupoids due to Ehresmann is a well known result. A remarkable generalisation of this equivalence, due to Mackenzie, is the equivalence of principal bundle extensions with those transitive Lie groupoids over the total space of a principal bundle, which also admit an action of the structure group

Twisted-Product Categorical Bundles [PDF]
, 2015 Categorical bundles provide a natural framework for gauge theories involving multiple gauge groups. Unlike the case of traditional bundles there are distinct notions of triviality, and hence also of local triviality, for categorical bundles. We study categorical principal bundles that are product bundles in the categorical sense, developing the ...

Investigating the Effects of Differential Item Functioning on Proficiency Classification
Applied Psychological Measurement, 2018 This study provides a comprehensive evaluation of the effects of differential item functioning (DIF) on proficiency classification. Using Monte Carlo simulation, item- and test-level DIF magnitudes were varied systematically to investigate their impact ...

A functional-analytic construction of the stochastic parallel transport in Hermitian bundles over Riemannian manifolds [PDF]
arXiv, 2022 This article presents a purely functional-analytic construction of the concept of stochastic parallel transport in Hermitian bundles over Riemannian manifolds. As a byproduct, we also obtain a form of the Feynman-Kac formula in vector bundles that is, to our best knowledge, the most general found so far.
