Parametric Bootstrap Mantel‐Haenszel Statistic for Aggregated Testlet Effects
Journal of Educational Measurement, Volume 62, Issue 4, Page 503-530, Winter 2025.Abstract While testlets have proven useful for assessing complex skills, the stem shared by multiple items often induces correlations between responses, leading to violations of local independence (LI), which can result in biased parameter and ability estimates.

The Anatomical Record, Volume 308, Issue 11, Page 2994-3006, November 2025.Abstract The canine of saber‐toothed predators represents one of the most specialized dental structures known. Hypotheses about the function of hypertrophied canines range from display and conspecific interaction, soft food processing, to active prey acquisition.

Understanding the war in Ukraine: Comparing knowledge and bias in Russia and the U.S.
Political Psychology, Volume 46, Issue 5, Page 1168-1185, October 2025.Abstract What mass publics know about foreign affairs is of great importance in international politics. Knowledge and ignorance probabilistically delimit the range of opinions likely to form on foreign affairs issues. Military strategists understand the importance of “information warfare,” since publics apply foreign affairs knowledge to form opinions ...

Power estimation of tests in log-linear non-uniform association models for ordinal agreement
BMC Medical Research Methodology, 2011 Background Log-linear association models have been extensively used to investigate the pattern of agreement between ordinal ratings. In 2007, log-linear non-uniform association models were introduced to estimate, from a cross-classification of two ...

Australian &New Zealand Journal of Statistics, Volume 67, Issue 3, Page 432-453, September 2025.ABSTRACT We investigate the use of multiple linked lists for population size estimation and to estimate the relationships between covariates appearing on the lists. Over the lists, the covariates aim to measure the same concept. The relationships between the covariates are not fully known because of missing values on the covariates: some cases do not ...

Size Matters: Effects of Propagule Size on Dispersal in Rivers
Water Resources Research, Volume 61, Issue 8, August 2025.Abstract Biological particles (e.g., bacteria, eggs, fruit/seeds and larvae) of a wide range of sizes (i.e., 10−6–10−1 m) are transported over various distances (i.e., 100–104 m) downstream in rivers. We examined the effects of propagule size on downstream dispersal by releasing biodegradable microbeads (density ∼ 1,200 kg m−3) of three size classes ...

A Complete Characterization of the Linear, Log-Linear, and Semi-Log Incomplete Demand System Models
Journal of Agricultural and Resource Economics, 2002 This study extends LaFrance's (1985, 1986, 1990) previous research by deriving the necessary parameter restrictions for two additional classes of incomplete demand system models to be integrable.
