Schools have increasingly adopted multitier systems of support to address a variety of educational aims. Despite their grounding in behavioral science and the public health model of prevention, in many settings there has been a shift from a foundational focus on behavioral principles to emphasize categorization and treatment of "top of the triangle" or "Tier 3" students. Herein, we first discuss how such emphasis on situating individuals, rather than behaviors, within the continuum of supports is counter to the principles and goals of MTSS, as well as undermining efforts to support prevention and social justice.

In response to patterns of educational inequity, many schools implement system-wide behavioral frameworks to reduce exclusionary discipline. School-wide positive behavior supports (SWPBS) is one such framework that seeks to support socially appropriate behavior by enhancing the capacity of schools to implement research-validated practices. However, there remains to be a systematic analysis of the extent to which SWPBS improves educational equity by reducing disparities in exclusionary discipline.

One key aspect of the human experience is our ongoing stream of thoughts. These thoughts can be broadly categorized into various dimensions, which are associated with different impacts on mood, well-being, and productivity. While the past literature has often identified eye movements associated with a specific thought dimension (task-relatedness) during experimental tasks, few studies have determined if these various thought dimensions can be classified by oculomotor activity during naturalistic tasks.

An ongoing challenge in polymer chemistry is accessing diverse block copolymers from multiple polymerization mechanisms and monomer classes. One strategy to accomplish this goal without intermediate compatibilization steps is the use of universal mediators. Thiocarbonyl thio (TCT) functional groups are well-known mediators to combine radical with either cationic or anionic polymerization, but a sequential cationic-anionic universal mediator system has never been reported.

Equilibrium phase behavior of gyroid-forming diblock polymer thin films.

J Chem Phys

August 2024

Department of Chemical Engineering and Materials Science, University of Minnesota - Twin Cities, 421 Washington Avenue SE, Minneapolis, Minnesota 55455, USA.

Thin-film confinement of self-assembling block polymers results in materials with myriad potential applications-including membranes and optical devices-and provides design parameters for altering phase behavior that are not available in the bulk, namely, film thickness and preferential wetting. However, most research has been limited to lamella- and cylinder-forming polymers; three-dimensional phases, such as double gyroid (DG), have been observed in thin films, but their phase behavior under confinement is not yet well understood. We use self-consistent field theory to predict the equilibrium morphology of bulk-gyroid-forming AB diblock polymers under thin-film confinement.

Background And Hypothesis: The human visual system streamlines visual processing by suppressing responses to textures that are similar to their surrounding context. Surround suppression is weaker in individuals with schizophrenia (ISZ); this altered use of visuospatial context may relate to the characteristic visual distortions they experience.

Study Design: To understand atypical surround suppression in psychotic psychopathology, we investigated neurophysiological responses in ISZ, healthy controls (HC), individuals with bipolar disorder (IBP), and first-degree relatives (ISZR/IBPR).
