An Online Growth Mindset Intervention in a Sample of Rural Adolescent Girls

Background. Students living in rural areas of the United States exhibit lower levels of educational attainment than their suburban counterparts. Innovative interventions are needed to close this educational gap. Aims. We investigated whether an online growth mindset intervention could be leveraged to promote academic outcomes. Sample. We tested the mindset intervention in a sample of 222 10th-grade adolescent girls (M age=15.2; 38% White, 25% Black, 29% Hispanic) from four rural, low-income high schools in Southeastern United States. Methods. We conducted a randomized controlled trial to test the efficacy of the growth mindset intervention, relative to a sexual health programme. We used random sampling and allocation procedures to assign girls to either the mindset intervention (n-115) or an attention-matched control programme (n-107). We assessed participants at pre-test, immediate post-test, and 4-month follow up. Results. Relative to the control condition, students assigned to the mindset intervention reported stronger growth mindsets at immediate post-test and 4-month follow up. Although the intervention did not have a total effect on academic attitudes or grades, it indirectly increased motivation to learn, learning efficacy and grades via the shifts in growth mindsets. Conclusions. Results indicate that this intervention is a promising method to encourage growth mindsets in rural adolescent girls

Wealth inequality and activism: Perceiving injustice galvanizes social change but perceptions depend on political ideologies

What motivates people to engage in activism against wealth inequality? The simple answer is, perceiving injustice. However, the current work demonstrates that these perceptions depend on political ideologies. More specifically, for political liberals who frequently question the fairness of the economic system, messages simply describing the extent of the inequality (distributive injustice) are enough to motivate activism (Study 1). For political conservatives, who are inclined to believe that inequality results from fair procedures, messages must also detail how the system of economic forces is unjust (procedural injustice; Studies 2 and 3). Together, these studies suggest perceiving injustice can galvanize social change, but for conservatives, this means more than simply outlining the extent of the inequality

Randomized Trial of a Single-Session Growth Mind-Set Intervention for Rural Adolescents’ Internalizing and Externalizing Problems

Objective. Adolescents living in rural regions of the United States face substantial barriers to accessing mental health services, creating needs for more accessible, non-stigmatizing, briefer interventions. Research suggests that single-session “growth mindset” interventions (GM-SSIs)—which teach the belief that personal traits are malleable through effort—may reduce internalizing and externalizing problems in adolescents. However, GM-SSIs have not been evaluated among rural youth, and their effects on internalizing and externalizing problems have not been assessed within a single trial, rendering their relative benefits for different problem types unclear. We examined whether a computerized GM-SSI could reduce depressive symptoms, social anxiety symptoms, and conduct problems in adolescent girls from rural areas of the U.S. Method. Tenth-grade girls (N=222, M age=15.2, 38% white, 25% Black, 29% Hispanic) from four rural, low-income high schools in the Southeastern United States were randomized to receive a 45-minute GM-SSI or a computer-based, active control program, teaching healthy sexual behaviors. Girls self-reported depression symptoms, social anxiety symptoms, and conduct problem behaviors at baseline and four-month follow-up. Results. Relative to girls in the control group, girls receiving the GM-SSI reported modest but significantly greater reductions in depressive symptoms (d=.23) and likelihood of reporting elevated depressive symptoms (d=.29) from baseline to follow-up. GM-SSI effects were nonsignificant for social anxiety symptoms, although a small effect size emerged in the hypothesized direction (d=.21), and nonsignificant for change in conduct problems (d=.01). Conclusions. A free-of-charge, 45-minute GM-SSI may help reduce internalizing distress, especially depression—but not conduct problems—in rural adolescent girls

Limitations of Absolute Current Densities Derived from the Semel & Skumanich Method

Semel and Skumanich proposed a method to obtain the absolute electric current density, |Jz|, without disambiguation of 180 degree in the transverse field directions. The advantage of the method is that the uncertainty in the determination of the ambiguity in the magnetic azimuth is removed. Here, we investigate the limits of the calculation when applied to a numerical MHD model. We found that the combination of changes in the magnetic azimuth with vanishing horizontal field component leads to errors, where electric current densities are often strong. Where errors occur, the calculation gives |Jz| too small by factors typically 1.2 ~ 2.0.Comment: 10 pages, 4 figures.

Initial Validation of the Suicide Competency Assessment Form among Behavioral Health Staff in the National Health Services (NHS) Trust. Archives of Suicide Research

Objective: The Suicide Competency Assessment Form (SCAF) provides a framework for suicide prevention skills training. This study assessed SCAF psychometric properties in a sample of behavioral health staff. Method: A cross-sectional survey of National Health Services (NHS) staff from varying disciplines (N=170) was conducted. Results: The SCAF yielded a one-factor structure with high internal consistency. Nursing assistants reported lower SCAF scores compared to other professionals. SCAF scores demonstrated positive associations with prior suicide prevention training, job enthusiasm, and several suicide/self-injury prevention outcome expectations (i.e., optimism working with self-harming patients and perceived ability to help self-harming patients). SCAF scores further demonstrated incremental validity in the form of multivariate model associations with suicide/self-injury prevention outcome expectations. Improved job satisfaction mediated the pathway from SCAF scores to perceived ability to help self-harming patients. Conclusion: The SCAF can be utilized in suicide prevention training and clinical supervision

SIMcheck:A toolbox for successful super-resolution structured illumination microscopy

Three-dimensional structured illumination microscopy (3D-SIM) is a versatile and accessible method for super-resolution fluorescence imaging, but generating high-quality data is challenging, particularly for non-specialist users. We present SIMcheck, a suite of ImageJ plugins enabling users to identify and avoid common problems with 3D-SIM data and assess resolution and data quality through objective control parameters. Additionally, SIMcheck provides advanced calibration tools and utilities for common image processing tasks. This open-source software is applicable to all commercial and custom platforms and will promote routine application of super-resolution SIM imaging in cell biology
