Sustainable Development, EarlyView.ABSTRACT Nitrogen (N) application creates negative externalities via nitrate (NO3−) leaching that threatens human health and the emission of nitrous oxide (N2O), a potent greenhouse gas. This study determines socially optimal nitrogen application rates (SONR) for corn and wheat by considering the social costs of both pollutants. The assessment includes

lordif: An R Package for Detecting Differential Item Functioning Using Iterative Hybrid Ordinal Logistic Regression/Item Response Theory and Monte Carlo Simulations [PDF]
Logistic regression provides a flexible framework for detecting various types of differential item functioning (DIF). Previous efforts extended the framework by using item response theory (IRT) based trait scores, and by employing an iterative process ...

Implementing Argument‐Based Validity in Second Language Research on Individual Differences
TESOL Quarterly, EarlyView.Abstract Quantitative meta‐syntheses focusing on the psychometric properties of measurement tools in second and foreign language (L2) individual differences (ID) research have drawn scholars' attention to the quality of data collection instruments (Plonsky & Derrick, 2016; Sudina, 2023).

Handwritten Versus Typed Notes: The Impact of Note‐Taking Modes in Second Language Listening Tests
TESOL Quarterly, EarlyView.Abstract Technological advancements have influenced note‐taking practices in classrooms as well as their treatment in standardized language assessments. Many high‐stakes English listening tests (e.g., TOEFL iBT, IELTS) include varying note‐taking guidelines, often established without empirical support.

Statistical Equivalence Testing Approaches for Mantel–Haenszel DIF Analysis [PDF]
, 2017 The null hypothesis test used in differential item functioning (DIF) detection tests for a subgroup difference in item-level performance—if the null hypothesis of “no DIF” is rejected, the item is flagged for DIF. Conversely, an item is kept in the test

High Voltage, EarlyView.ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Rasch Analysis and Interval-Level Scaling of the Positive and Negative Affect Schedule (PANAS) Across Cultures. [PDF]
Int J PsycholABSTRACT Affective state investigation requires precise measurement that satisfies parametric statistical assumptions for reliable and valid cross‐data comparisons. The psychometric properties of the 20‐item Positive and Negative Affect Schedule (PANAS) are satisfactory, but provide scores on an ordinal scale, which could be unsuitable for parametric ...

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...
