On the Wigner-Kirkwood Expansion of the Free Energy and the Evaluation of the Quantum Correction
Atoms, 2022 The Wigner-Kirkwood expansion of the quantum correction to the classical free energy is generally said to be in powers of ℏ2 and only its first few terms are presented.

A Penalty Approach to Differential Item Functioning in Rasch Models [PDF]
, 2012 A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the ...

Differential item functioning for items in Berger's HIV Stigma Scale: an analysis of cohorts from the Indian, Swedish, and US contexts [PDF]
, 2018 PURPOSE: To examine whether items in Berger's HIV Stigma Scale function differently with persons of different age, gender, and cultural backgrounds. METHODS: Secondary data from cohorts, collected in South India (n = 250), Sweden (n = 193), and the US (n

DIF in the Spanish Version of the Verbal Selective Reminding Test Using Samples From Hispanics in the United States, Mexicans, and Spaniards [PDF]
, 2019 Aim: Before a test can be used in the target population, it is necessary to demonstrate that there is measurement equivalence. One way to do this is by studying differential item functioning (DIF).

Theoretical study of the porosity effects on the shock response of graphitic materials
EPJ Web of Conferences, 2015 In this paper we present a theoretical study of the shock compression of porous graphite by means of combined Monte Carlo and molecular dynamics simulations using the LCBOPII potential. The results show that the Hugoniostat methods can be used with “pole”

Risk factors associated with neonatal sepsis of nosocomial origin in patients at a Mexican Hospital
Mexican Journal of Medical Research ICSA, 2012 Nosocomial neonatal sepsis (NNS) is one of the principal causes of childhood morbidity and mortality and has a large impact on public health. Therefore, our objective was to determine the prevalence and risk factors associated with NNS in patients at ...

MIMIC Models for Uniform and Nonuniform DIF as Moderated Mediation Models. [PDF]
, 2020 In this article, the authors describe how multiple indicators multiple cause (MIMIC) models for studying uniform and nonuniform differential item functioning (DIF) can be conceptualized as mediation and moderated mediation models.
