ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Assessing the Impact of Characteristics of the Test, Common-items, and Examinees on the Preservation of Equity Properties in Mixed-format Test Equating [PDF]
Preservation of equity properties was examined using four equating methods - IRT True Score, IRT Observed Score, Frequency Estimation, and Chained Equipercentile - in a mixed-format test under a common-item nonequivalent groups (CINEG) design.

Application of Alternative IRT models to IRT Assumption Violation
The purpose of this study is to investigate the most appropriate alternative IRT parameter estimation models among bi-factor model, testlet based model, and second-order IRT model when the IRT assumptions are not met. A simulation study was conducted to compare the alternative IRT parameter estimation models when the assumptions are unsatisfied. First,
