Putting ourselves together: School belonging, parental socialization, and teacher support of Latinx youth.

Limited research has considered how family and school factors combine to support Latinx students' academic achievement in early adolescence. We examined associations between parental academic socialization (PAS), teacher support (TS), school belonging, and achievement outcomes to understand the roles of family and teacher factors in youths' school belonging and achievement. Youth (N = 65, mean age = 11.74, SD = 1.11) and their parents completed questionnaires on school belonging, PAS, and TS, and we collected grade point average, standardized test results, and teacher perceptions of student skills and traits from their schools. Results indicated that TS, but not PAS, was negatively associated with school belonging and achievement. Belonging mediated the effect of TS on academic outcomes through a positive indirect relation. Findings implicate the role of school psychologists in guiding teacher support strategies for Latinx students. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Embracing measurement-based care within integrated primary care settings.

"Why should I care about doing Measurement-Based Care (MBC)?" This is a phrase that the editor often hears, either explicitly or implied, when working to champion and implement MBC within integrated primary care (IPC) settings. As an implementation and education specialist within the Veterans Health Administration (VHA) healthcare system, the editor has attended many MBC presentations and meetings where this question is uttered by frontline IPC clinicians, often frustrated with the growing demands on their practice. Many of these sentiments are usually framed around the assumption that MBC is not very important or useful, clinically speaking. This sets up a familiar debate of research versus practice: While many clinicians have heard MBC is "good for us," what accounts for the failure to implement MBC clinically? One of the major aims of this guest editorial is to invite the reader to consider the evidence base we have so far, rethink perceived barriers to MBC, and to ultimately decide for oneself that "the juice is worth the squeeze" for routine clinical practice.

Modeling reaction pathways of low energy particle deposition on polymer surfaces via first principle calculations.

The chemical processes that lead to polystyrene surface modification via low energy deposition of C(2)H(+), C(2)F(+), CH(2), CH(2)(+), and H(+) radicals and ions are examined using first principles calculations. Specifically, the reaction mechanisms responsible for products identified in classical molecular dynamics with reactive empirical bond-order potentials are examined using density functional theory. In addition, these calculations consider how the presence of charges on the incident particles changes the result for the CH(2) system through the comparison of barriers, transition states, and final products for CH(2) and CH(2)(+). The structures of the reaction species and energy barriers are determined using the B3LYP hybrid functional. Finally, CCSD/6-31G(d,p) single point energy calculations are carried out to obtain optimized energy barriers. The results indicate that the large variety of reactions occurring on the polystyrene surface are a consequence of complex interactions between the substrate and the deposited particles, which can easily be identified and characterized using advanced computational methodologies, such as first principle calculations.

Sediment contamination, by habitat, in the Tampa Bay estuarine system (1993-1999): PAHs, pesticides and PCBs.

More than 760 Tampa Bay (Florida, U.S.A.) sediment samples have been analyzed for organic contaminants (PAHs, organochlorine pesticides, and PCBs) since 1993. Data were analyzed to assess status by habitat (defined by overlapping salinity zones and sediment type). The habitats most degraded by PAHs and pesticides were generally located in lower salinity, fine-grained sediment habitats, which are typically confined to the Hillsborough River. PCB contamination was more common in mesohaline waters of the Palm and Hillsborough rivers. Higher salinity portions of the bay, where medium to coarse sand-sized sediments predominate, showed little evidence of contamination by PAHs, PCBs and pesticides other than lindane.

Análisis de esmalte grabado con ácido fosfórico y esmalte grabado con energía láser de CO2 usando la técnica de fluorescencia láser / An analysis of phosphoric acid and CO2 laser etched dental enamel using the laser fluorescence technique

El objetivo de este estudio fue buscar si el esmalte grabado con energía láser demostraba un nivel distinto de fluorescencia que el esmalte grabado con ácido fosfórico. Cinco molares extraídos fueron usados. Tres ventanas fueron formadas en la superficie bucal. La primera ventana sirvió como control; la segunda ventana fue grabada con láser CO2; la tercera ventana con ácido fosfórico. Una superficie de 1 mm2 fue analizada con un espectrómetro de fluorescencia láser. Cada mm2 fue examinado a intervalos de 50 micrones por un total de 400 veces. El valor de fluorescencia obtenido en la ventana control fue sustraído de los valores de fluorescencia obtenidos en la dos ventanas grabadas para determinar un valor incremental de fluorescencia por cada ventana grabada. El examen estadístico "paired t-test" mostró que el esmalte grabado con láser de CO2 tuvo un incremento de fluorescencia significativamente mayor (p=0.002). Este resultado parece indicar que el grabar esmalte con láser de CO2 aumenta su nivel de fluorescencia. Esto puede tener implicaciones positivas para reducir la desmineralización que ocurre en áreas de esmalte grabado
