Exploring perceptions and needs of rural teachers to enhance school psychologists\u27 advocacy and support of gender and sexual minority students

Gender and Sexual Minority (GSM) students are at a disproportionate risk for victimization in schools. They are especially vulnerable in schools that lack protective policies, have limited access to resources, and exist within conservative and unaccepting communities. These schools may be more common in rural communities. The purpose of the present study was to explore rural teachers’ perceptions of school climate and their readiness and willingness to support GSM students. Recommendations are provided for school psychologists to be able to understand and address their own schools’ needs in providing a positive school climate for GSM students

An Enzymatic Cyclopentyl[b]indole Formation Involved in Scytonemin Biosynthesis

Previous studies of the biosynthetic enzymes involved in the assembly of scytonemin (1), a cyanobacterial sunscreen, have identified β-ketoacid 2 as an important intermediate that is produced by ThDP-dependent enzyme ScyA. We now report that ScyC, previously annotated as a hypothetical protein, catalyzes cyclization and decarboxylation of 2 to generate ketone 5. Assembly of the cyclopentyl[b]indole structure in this manner has little precedent in the chemical literature. Additional mechanistic experiments have revealed that cyclization likely precedes decarboxylation and that the latter event may provide a driving force for cyclopentane formation.Chemistry and Chemical Biolog

Investigating the Initial Steps in the Biosynthesis of Cyanobacterial Sunscreen Scytonemin

The cyanobacterial natural product scytonemin (1) functions as a sunscreen, absorbing harmful UV-A radiation. Using information from a recently identified gene cluster, we propose a biosynthetic route to this pigment. We also report the characterization of two enzymes, NpR1275 and NpR1276, which are involved in the initial stages of this pathway. A regioselective acyloin reaction between indole-3-pyruvic acid (4) and p-hydroxyphenylpyruvic acid (5) is a key step in assembling the carbon framework of a proposed monomeric scytonemin precursor (2).Chemistry and Chemical Biolog

Stochastic domain decomposition for time dependent adaptive mesh generation

The efficient generation of meshes is an important component in the numerical solution of problems in physics and engineering. Of interest are situations where global mesh quality and a tight coupling to the solution of the physical partial differential equation (PDE) is important. We consider parabolic PDE mesh generation and present a method for the construction of adaptive meshes in two spatial dimensions using stochastic domain decomposition that is suitable for an implementation in a multi– or many–core environment. Methods for mesh generation on periodic domains are also provided. The mesh generator is coupled to a time dependent physical PDE and the system is evolved using an alternating solution procedure. The method uses the stochastic representation of the exact solution of a parabolic linear mesh generator to find the location of an adaptive mesh along the (artificial) subdomain interfaces. The deterministic evaluation of the mesh over each subdomain can then be obtained completely independently using the probabilistically computed solutions as boundary conditions. The parallel performance of this general stochastic domain decomposition approach has previously been shown. We demonstrate the approach numerically for the mesh generation context and compare the mesh obtained with the corresponding single domain mesh using a representative mesh quality measure

Validating a Definition of Relapse in Anorexia Nervosa

There is currently no consensus on the definition of “relapse” in anorexia nervosa (AN). This study sought to extend recent theoretical work exploring relapse in AN by comparing eighttheory-driven definitions of relapse constructs comprised of combinations of physical (i.e., weight status), cognitive (e.g., shape and weight concerns), and behavioral (e.g., bingeing and purging) symptoms, ranging from full-threshold DSM-5 AN to the presence of only disordered eating cognitions or only disordered eating behaviors in the absence of other symptoms. Among26 individuals with a lifetime history of AN who had reached recovery, five participants met criteria for relapse over the course of the study. We discuss patterns observed in these individuals compared to those who did not relapse. A small sample size limits the conclusions that can be drawn, though the authors encourage others to continue expanding upon this work with a larger sample size, ideally derived from multi-site studies.Master of Art
