A Comparison of Six DIF Detection Methods

open access: yes, 2019
In the context of educational measurement, a test item is identified as differentially functioning across groups when the probability an examinee’s response to it depends on group membership.

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Assessment fairness at the nexus of validity: Linking fairness threats to score meaning

open access: yesMedical Education, EarlyView.
Abstract Introduction Nearly a century after Kelley's seminal work Interpretation of educational measurements, we revisit the concept of validity to argue that fairness is not a downstream equity add‐on but a core requirement throughout the assessment lifecycle.

Assessing the Effectiveness of Workers' Selection Exams: The Case of the Bank of Italy

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT High‐stakes exams can be used to rank and select candidates for job openings, and the ability of those selected hinges on the design of the exam. I propose a method to model candidates' performance to assess how effective the exam is at selecting high‐ability candidates.

Optimal Export Taxes in Global Value Chain

open access: yesThe World Economy, EarlyView.
ABSTRACT The determinants and optimality of implemented export taxes have long been understudied. In this work, I analyze how a country's optimal export taxes on products are influenced by their usage as inputs in traded final products. I decompose the influence of input–output linkages in the Global Value Chain (GVC) on optimal export policy into ...

On the Hardness of Switching to a Small Number of Edges

open access: yesJournal of Graph Theory, Volume 113, Issue 2, Page 237-251, October 2026.
ABSTRACT Seidel's switching is a graph operation which makes a given vertex adjacent to precisely those vertices to which it was non‐adjacent before, while keeping the rest of the graph unchanged. Two graphs are called switching‐equivalent if one can be made isomorphic to the other one by a sequence of switches. Jelínková et al. [DMTCS 13, no. 2, 2011]

Differential Item Functioning on the Patient Health Questionnaire 8 by Disease Subtype, Language, Sex, and Age Among People With Systemic Sclerosis: A Scleroderma Patient‐Centered Intervention Network Cohort Study

open access: yesArthritis Care &Research, Volume 78, Issue 9, Page 1140-1148, September 2026.
Objective Somatic items used in depression assessments can potentially overlap with symptoms related to physical illness, including systemic sclerosis (SSc). No studies have looked at whether somatic depression items may be influenced by diffuse versus limited SSc disease subtypes, which are associated with varying degrees of symptom presentation.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Spectral Compensation Strategy for Radical‐Induced Dye Degradation in Liquid Crystal Polymer Composites

open access: yesAdvanced Optical Materials, Volume 14, Issue 33, 4 September 2026.
A spectral compensation strategy is introduced to overcome radical‐induced degradation of dichroic dyes during UV photopolymerization. By incorporating a complementary photochromic liquid‐crystalline dye, broadband optical attenuation is preserved without disrupting photopolymerization, enabling high‐contrast and durable dye‐doped liquid crystal ...
