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 ...

Molecular diversity of arbuscular mycorrhizal fungi colonising Hyacinthoides non-scripta (bluebell) in a seminatural woodland [PDF]

, 1999
Arbuscular mycorrhizal (AM) fungi form symbiotic associations with plant roots. Around 150 species have been described and it is becoming clear that many of these species have different functional properties.

Population Size Estimation Using Covariates Having Missing Values and Measurement Error: Estimating Ethnic Group Sizes in New Zealand

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 ...

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 ...

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.

Pupil Fluctuations Signal Intentional Forgetting of Natural Scenes

Psychophysiology, Volume 62, Issue 8, August 2025.
ABSTRACT Studies have revealed that information can be intentionally forgotten when instructed, commonly studied in the laboratory with the directed forgetting (DF) procedure. The current investigation examined pupillometric signals associated with intentional forgetting, as the pupil reflects the activity in the locus coeruleus–norepinephrine (LC‐NE ...

Cardiac Interoceptive Accuracy: An Empirical Comparison of Three Ability Measures

Psychophysiology, Volume 62, Issue 6, June 2025.
ABSTRACT There are several measures used to assess one's ability to perceive their heartbeat (cardiac interoceptive accuracy). These can be categorized into two main task types: tracking (e.g., motor tracking, heartbeat counting) and discrimination (e.g., two‐ and multi‐interval).
