Applying modern measurement approaches to constructs relevant to evidence-based practice among Canadian physical and occupational therapists

Implementation Science, 2018
Background Evidence-based practice (EBP) is a complex process. To quantify it, one has to also consider individual and contextual factors using multiple measures.

Rasch-based high-dimensionality data reduction and class prediction with applications to microarray gene expression data [PDF]

Expert Systems with Applications, 2010;37(7):5178-5185, 2010
Class prediction is an important application of microarray gene expression data analysis. The high-dimensionality of microarray data, where number of genes (variables) is very large compared to the number of samples (obser- vations), makes the application of many prediction techniques (e.g., logistic regression, discriminant analysis) difficult.

Bevorzugte Alkan‐Komplexierung: Kristallisation eines kationischen Mangan(I)‐Pentan σ‐Komplexes aus der Lösung

Angewandte Chemie, EarlyView.
Oxidation von Mn2(CO)10 unter pseudo‐Gasphasenbedingungen generiert den schwach koordinierten 16‐Valenzelektronenkomplex [Mn(CO)5]+ als Intermediat, der n‐Pentan binden kann, da dieses der am stärksten bindende Ligand im System ist. Drei Isomere dieses Komplexes wurden mit Tieftemperatur‐NMR‐Spektroskopie und Einkristall‐Röntgenbeugung untersucht.

Rasch analysis suggests that health assessment questionnaire II is a generic measure of physical functioning for rheumatic diseases: a cross-sectional study

Health and Quality of Life Outcomes, 2018
Background Versions of the Health Assessment Questionnaire (HAQ) are commonly used to measure physical functioning across multiple rheumatic diseases but there has been no clear demonstration that any HAQ version is actually generic.

A Spectral Approach to Item Response Theory [PDF]

arXiv, 2022
The Rasch model is one of the most fundamental models in \emph{item response theory} and has wide-ranging applications from education testing to recommendation systems. In a universe with $n$ users and $m$ items, the Rasch model assumes that the binary response $X_{li} \in \{0,1\}$ of a user $l$ with parameter $\theta^*_l$ to an item $i$ with parameter

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

The Language ENvironment Analysis (LENA) System in Toddlers With Early Indicators of Autism: Test–Retest Reliability and Convergent Validity With Clinical Language Assessments

Autism Research, EarlyView.
ABSTRACT Clinical language assessments often influence the types of services that autistic children are eligible to receive. However, these assessments often take place outside of the child's natural language environment. In this study, we assess the potential of using naturalistic language processing technology, the Language ENvironment Analysis (LENA)
