Testing for heterogeneous factor loadings using mixtures of confirmatory factor analysis models

open access: yesFrontiers in Psychology, 2010
The current study assessed the viability of mixture confirmatory factor analysis (CFA) for measurement invariance testing by evaluating the ability of mixture CFA models to identify differences in factor loadings across populations with identical mean ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Fairness in classroom assessment: development and validation of a questionnaire

open access: yesLanguage Testing in Asia, 2022
Although fairness in assessment practices has gained noticeable attention over the recent years, there has been a long-lasting study to design and validate a questionnaire to measure it from a psychometric perspective.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Construction and Psychometric Characteristics of the Parental Sexual Education Styles Questionnaire

open access: yesTaḥqīqāt-i ̒Ulūm-i Raftārī, 2020
Aim and Background: The attitude of parents to their children's sexual education has an effect on their sexual behavior and interaction with their children. No specific measurement tool has ever been developed to evaluate and measure this matter. The aim

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Self-Regulated Online Learning Instrument Adaptation: A Measurement Model

open access: yesJournal of Learning for Development
Self-regulated online learning (SOL) is the self-regulation of students who study independently in online learning. Jansen et al. (2016) show that self-regulated online learning (SOL) has five dimensions or factors: 1) metacognitive skills, 2) time ...

The Factor Structure of the CA-MIR as Evaluated Using Confirmatory Factor Analysis

open access: yesFrontiers in Psychology, 2018
Introduction: The aim of the current study was to evaluate the factor structure of the CArtes- Modèles Individuels de Relations (CA-MIR), a self-report questionnaire designed to tap into the relational strategies of adults that was developed by a French ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
