In this study we assessed the construct validity of the recently published White Racial Affect Scale (Grzanka et al., 2020). Specifically, we assessed the convergent, criterion-related, and incremental evidence for construct validity of the White guilt, White shame, and White defensiveness (called "White negation" in the original article) factors. We used a video stimulus to trigger state guilt and shame in participants as part of the construct validity investigation. White adults in the United States signed up for the study online ( = 262) and watched a 5-min video stimulus and completed questionnaires before and after the video. Results of this study replicated many of the findings from the original White Racial Affect Scale validation study (Grzanka et al., 2020). We found strong evidence of construct validity for the White guilt and White defensiveness factors and mixed evidence for the White shame factor. We discuss directions for future research and implications for potential interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Background: Peripheral nerve sheath tumors (PNSTs) encompass entities with different cellular differentiation and degrees of malignancy. Spatial heterogeneity complicates diagnosis and grading of PNSTs in some cases. In malignant PNST (MPNST) for example, single cell sequencing data has shown dissimilar differentiation states of tumor cells.

Efficient planning is a distinctive hallmark of intelligence in humans, who routinely make rapid inferences over complex world contexts. However, studies investigating how humans accomplish this tend to focus on naive participants engaged in simplistic tasks with small state spaces, which do not reflect the intricacy, ecological validity, and human specialization in real-world planning. In this study, we examine the street-by-street route planning of London taxi drivers navigating across more than 26,000 streets in London (United Kingdom).

Emerging research indicates that dehumanization may occur in couples with serious consequences; however, this research is in its infancy, and there is a need to integrate dehumanization perspectives with key theories of intimate relationships to best understand this phenomenon. Drawing on work on individuation in couples, we present an integrated framework of dehumanizing deindividuation that is characterized by derogation (viewing a partner with contempt), disregard (ignoring or overlooking a partner), and denial of autonomy (restricting a partner's self-determination). We present data from two samples highlighting the reliability and validity of a new measure, the Dehumanizing Deindividuation in Couples (DDC) scale, which was internally consistent and had excellent construct replicability.

The present work reports the synthesis, characterization, and excited state photo-physical studies of two copper(II) compounds, 1 & 2, which show interference-free emission with homocysteine (Hcy). Cu(II) complexes offer an orthogonal detection strategy involving fluorescence and electrochemical methods, paving the way for improved point-of-care diagnostics and early cardiovascular diseases intervention. The reduction-induced emission enhancement (RIEE) of Cu complexes facilitates the fluorescence measurement of Hcy at physiological pH.

One key challenge in the study of nonadiabatic dynamics in open quantum systems is to balance computational efficiency and accuracy. Although Ehrenfest dynamics (ED) is computationally efficient and well-suited for large complex systems, ED often yields inaccurate results. To address these limitations, we improve the accuracy of the traditional ED by adding a random force (E + σ).
