Joint copula‐based beta regression with covariate‐dependent dispersion for malaria indicators

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Malaria surveillance relies on multiple indicators that reflect different aspects of transmission and disease burden, yet these outcomes are often analyzed separately under constant‐variance assumptions. Such approaches may obscure residual dependence and heterogeneity in variability. Using Demographic and Health Survey data from Burkina Faso (

A Note on Model Complete Models and Generic Models [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
We prove that there are many maximum model complete (= generic) models, and that there exists an (uncountable) theory with no generic models.

Z‐residuals diagnostics for Cox models: Functional‐form misspecification versus nonproportional hazards

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Primary biliary cholangitis (PBC) is a progressive autoimmune cholestatic disease for which modelling death, with transplantation as a competing event, is clinically important. Cox proportional hazards (PH) models are widely used, but standard diagnostics detect lack of fit without distinguishing non‐PH from misspecified covariate functions ...

Wissenschaftliche Dokumente mit domänenspezifischen Inhalten: Entwicklung eines allgemeinen Modells für wissenschaftliche Dokumente umgesetzt als browserbasierter Editor [PDF]

open access: yes, 2014
Aktuelle Textverarbeitungsprogramme haben gerade bei der Erstellung von wissenschaftlichen Dokumenten große Defizite, da dort oft formale Modelle, wie z.B. Chemie-Moleküle, aus dem jeweiligen Fachgebiet (Domäne) benutzt werden müssen.

Förderung von naturwissenschaftlichem Argumentieren mithilfe von KI‐ und Peer‐Feedback – die Web‐App CLeVerAI_Argu

open access: yesCHEMKON, EarlyView.
Die Förderung naturwissenschaftlicher Argumentation stellt insbesondere in Socioscientific Issues (SSI) eine zentrale Herausforderung im Chemieunterricht dar. Digitale Lernumgebungen eröffnen neue Möglichkeiten, diese Prozesse durch adaptives Feedback und metakognitive Unterstützung zu fördern.

CD8+ T‐cells, CD86+ macrophages and TNF‐α signalling pathways are correlated with fetlock osteoarthritis in racehorses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background There is emerging evidence for the role of the immune system in osteoarthritis (OA) pathophysiology; however, little is known about how immune cells and the synovial transcriptome are altered in naturally occurring equine OA. Objectives To evaluate synovial fluid (SF) and synovial membrane (SM) immune cell populations and the SM ...

Impact of evidence‐based information on horse owners' misconceptions of colic

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Misconceptions can be defined as ‘false, persistent beliefs’ or ‘inaccurate, prior knowledge’ and can influence decision‐making. Objectives To investigate the impact of evidence‐based information on UK horse owners' decision‐making for colic. Study Design Mixed‐methods cross‐sectional study.
