DIF Detection With Zero-Inflation Under the Factor Mixture Modeling Framework.
Lee S, Han S, Choi SW. Lee S, et al. Educ Psychol Meas. 2022 Aug;82(4):678-704. doi: 10.1177/00131644211028995. Epub 2021 Jul 26. Educ Psychol Meas. 2022. PMID: 35754619 Free PMC article.
Response data containing an excessive number of zeros are referred to as zero-inflated data. When differential item functioning (DIF) detection is of interest, zero-inflation can attenuate DIF effects in the total sample and lead to underdetection of DIF item …

DIF Statistical Inference Without Knowing Anchoring Items.
Chen Y, Li C, Ouyang J, Xu G. Chen Y, et al. Psychometrika. 2023 Dec;88(4):1097-1122. doi: 10.1007/s11336-023-09930-9. Epub 2023 Aug 7. Psychometrika. 2023. PMID: 37550561 Free PMC article.
DIF analysis is confounded by the group difference in the latent trait distributions. Many DIF analyses require knowing several anchor items that are DIF-free in order to draw inferences on whether each of the rest is a DIF item, where the anchor items …

DIF Analysis with Unknown Groups and Anchor Items.
Wallin G, Chen Y, Moustaki I. Wallin G, et al. Psychometrika. 2024 Mar;89(1):267-295. doi: 10.1007/s11336-024-09948-7. Epub 2024 Feb 21. Psychometrika. 2024. PMID: 38383880 Free PMC article.
Traditional DIF analysis methods require knowing the comparison groups (reference and focal groups) and anchor items (a subset of DIF-free items). ...In the proposed framework, we model the unknown groups by latent classes and introduce item-specific DIF para …

The NFkappaB Dif is required for behavioral and molecular correlates of sleep homeostasis in Drosophila.
O'Hara MK, Saul C, Handa A, Cho B, Zheng X, Sehgal A, Williams JA. O'Hara MK, et al. Sleep. 2024 Aug 14;47(8):zsae096. doi: 10.1093/sleep/zsae096. Sleep. 2024. PMID: 38629438 Free PMC article.
Here we show that Dif regulates daily sleep and recovery sleep following prolonged wakefulness. Mutants of Dif showed reduced daily sleep and suppressed recovery in response to sleep deprivation. Pan-neuronal knockdown of Dif strongly suppressed daily sleep, …

Differential item functioning (DIF) and the Mini-Mental State Examination (MMSE). Overview, sample, and issues of translation.
Ramirez M, Teresi JA, Holmes D, Gurland B, Lantigua R. Ramirez M, et al. Med Care. 2006 Nov;44(11 Suppl 3):S95-S106. doi: 10.1097/01.mlr.0000245181.96133.db. Med Care. 2006. PMID: 17060840 Review.
The articles in this section illustrate the use of different methods to examine DIF in relation to English and Spanish language administration of the MMSE. OBJECTIVES: The aim of this article is to provide a context for interpretation of the findings contained in the follo …

Direct Immunofluorescence.
Robinson MR. Robinson MR. J Clin Aesthet Dermatol. 2023 Dec;16(12 Suppl 2):S33-S35. J Clin Aesthet Dermatol. 2023. PMID: 38464740 Free PMC article.
Improper use of DIF can lead to false negatives, decreased diagnostic yield, and poor resource utilization. This article provides instruction on the appropriate indications and biopsy site selection for DIF. Three examples of skin diseases in which DIF would …

Not all DIF is shaped similarly.
De Boeck P, Cho SJ. De Boeck P, et al. Psychometrika. 2021 Sep;86(3):712-716. doi: 10.1007/s11336-021-09772-3. Epub 2021 Jun 5. Psychometrika. 2021. PMID: 34089430

[Progress on XerCD/dif site-specific recombination].
Tian DQ, Wang YM, Zheng T. Tian DQ, et al. Yi Chuan. 2012 Aug;34(8):1003-8. doi: 10.3724/sp.j.1005.2012.01003. Yi Chuan. 2012. PMID: 22917905 Review. Chinese.
The CTXphi integration site overlaps with the dif site. The wide distribution of XerCD recombinase and dif site among bacteria genome suggests that it may be universal in resolve of chromosome dimers and phage integration. In this article, we reviewed the research p …

Practical Direct Immunofluorescence.
Kim RH, Brinster NK. Kim RH, et al. Am J Dermatopathol. 2020 Feb;42(2):75-85. doi: 10.1097/DAD.0000000000001516. Am J Dermatopathol. 2020. PMID: 31990699 Review.
Direct immunofluorescence (DIF) remains a valuable tool that may be underused because of perceived challenges in the interpretation, limitations, and processing of DIF specimens. The aim of this review is to provide a practical guide for appropriately incorporating …
