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

, 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 ...

Evaluating the realism of double moment parameterised particle size distributions in a midlatitude frontal ice cloud with complex microphysics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Uncertainties in the representation of ice particle size distributions (PSDs) cause inaccuracies in parameterisations of clouds. In this study, observed PSDs from a midlatitude frontal case study are compared with gamma PSDs with the same concentration and ice water content.

Exploring rater judging behaviour using the many-facet rasch model [PDF]

, 2007
Performance assessment, unlike the traditional fixed-response assessment, has features peculiar to its assessment setting (the task choice, the task processing conditions, the raters,the rating scale, and the rating procedures) that make it much more ...

Exploring Barriers on the Path to B Corp Certification

Sustainable Development, EarlyView.
ABSTRACT B Corp companies have become a benchmark for sustainability and corporate social responsibility today. However, it is striking that of the more than 285,000 companies that use the B Impact Assessment (BIA) to measure their performance, only around 9400 have managed to achieve certification.

Marker effects and examination reliability: a comparative exploration from the perspectives of generalizability theory, Rasch modelling and multilevel modelling [PDF]

, 2013
This study looked at how three different analysis methods could help us to understand rater effects on exam reliability. The techniques we looked at were: generalizability theory (G-theory) item response theory (IRT): in particular the Many-Facets ...

Development of the PsAQoL: a quality of life instrument specific to psoriatic arthritis [PDF]

, 2004
Background: Patient reported outcome measures used in studies of psoriatic arthritis (PsA) have been found to be inadequate for determining the impact of the disease from the patient’s perspective.

Low‐Cost Ambient Pressure Drying Approach for Highly Porous Nanomaterial Structures

Small Methods, EarlyView.
We propose a simple, low‐cost method to dry highly porous nanomaterial structures at ambient temperature and pressure. Using low surface tension solvents, this technique minimizes capillary forces, preventing pore collapse and material shrinkage. This bypasses the need for expensive and size‐limiting critical point drying, enabling scalable production ...

Flexible Rasch Mixture Models with Package psychomix [PDF]

Measurement invariance is an important assumption in the Rasch model and mixture models constitute a flexible way of checking for a violation of this assumption by detecting unobserved heterogeneity in item response data.

What Program for Love in the 21st Century? Thinking With and Beyond Luhmann

Systems Research and Behavioral Science, EarlyView.
ABSTRACT From a sociological perspective, the paper examines how normative frameworks for intimate relationships have changed since the publication of Luhmann's Love as Passion (1982). Building on Luhmann's notion of a program for love, we discuss his claim that late 20th century love semantics were organized around a program of understanding. We argue

Linguistic Variation across Instructional Segments in International Teaching Assistants' Discourse: A Corpus‐Based Analysis

TESOL Quarterly, EarlyView.
Abstract This study investigates internal linguistic variation in the instructional discourse of international teaching assistants (ITAs) by segmenting their mini‐lecture performances into four discourse types: introduction, lecture, conclusion, and audience interaction.
