A Modularized Higher-Order Diagnostic Classification Model for Clustered Attribute Hierarchies

Minho Lee, Yon Soo Suh

Recognizing that complex networks of skills typically exhibit hierarchical and modular organization, this article presents a Modularized Higher-Order Diagnostic Classification Model (MHO-DCM) designed to capture hierarchical relationships among attributes organized into clustered subdomains. Central to the proposed method is a representation of …

Composite marginal likelihood estimation of higher‐order diagnostic classification models under high dimensionality

Minho Lee, Yon Soo Suh

Although full-information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high-dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large-scale assessments, psychological testing and longitudinal studies involving many …

The unpredictable nature of microbiological responses to metals in real-world contaminated soils: A review

Microbial responses, such as biomass or enzymatic activity, are commonly used to evaluate metal toxicity in contaminated soils. However, multiple studies have demonstrated the existence of microbial tolerance and resilience to metals. The adaptive responses of soil microorganisms to metal stress may …

Bridging Science and Practice: Literature Review and Expert Insights on Per‐ and Polyfluoroalkyl Substances Transport Modeling

Mahsa Modiri Gharehveran, John F. Stults, David T. Adamson, Craig E. Divine et autres

ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) present significant challenges in modeling fate and transport within the subsurface, including both unsaturated and saturated zone, due to their amphiphilic nature, complex partitioning behavior, and partial transformation. Their transport within porous media is highly complex …

Novel dough strength of ‘Paradox’, ‘Breadbox’, and ‘Firebox’ hard red winter wheat provides value as ingredient flour

Jayne E. Bock, Itunuoluwa Adegbite, Andrew D. Hoelscher, Kathy Brower et autres

Abstract Farmer seed purchase patterns historically drive end‐use quality into a subordinate position to yield enhancement and protection in hard red winter (HRW) wheat ( Triticum aestivum L.) breeding programs. Evolving consumer food purchase decisions could conceivably swing this priority pendulum back …
