Boredom begets boredom: An experience sampling study on the impact of teacher boredom on student boredom and motivation.

Background: Boredom is a common complaint among students. Boredom was previously found to be negatively associated with academic outcomes, such as academic motivation, strategies, and achievement. It is of interest to understand students' in-class boredom, especially factors that might exacerbate it.

A well-slept teacher is a better teacher: A multi-respondent experience-sampling study on sleep, stress, and emotional transmission in the classroom.

The present study examined the impact of sleep, stress, and negative activating emotions of high-school teachers on their students' affective experience, academic motivation, and in-class satisfaction. It is hypothesized that teachers' sleep quality and stress have a positive influence on their own nervousness and irritability. With reference to the emotional crossover theory, teachers' nervousness and irritability are hypothesized to intensify students' nervousness and irritability and subsequently dampen their academic motivation and in-class satisfaction.

Predicting Future High-Cost Schizophrenia Patients Using High-Dimensional Administrative Data.

Background: The burden of serious and persistent mental illness such as schizophrenia is substantial and requires health-care organizations to have adequate risk adjustment models to effectively allocate their resources to managing patients who are at the greatest risk. Currently available models underestimate health-care costs for those with mental or behavioral health conditions.

Objectives: The study aimed to develop and evaluate predictive models for identification of future high-cost schizophrenia patients using advanced supervised machine learning methods.

ROOT UV-B SENSITIVE2 acts with ROOT UV-B SENSITIVE1 in a root ultraviolet B-sensing pathway.

Ultraviolet B light (UV-B; 280-320 nm) perception and signaling are well-known phenomena in plants, although no specific UV-B photoreceptors have yet been identified. We previously reported on the root UV-B sensitive1 (rus1) mutants in Arabidopsis (Arabidopsis thaliana), which display a block to development under very-low-fluence-rate UV-B (<0.1 mumol m(-2) s(-1)) after the seedling emerges from the seed.

Role of root UV-B sensing in Arabidopsis early seedling development.

All sun-exposed organisms are affected by UV-B [(UVB) 280-320 nm], an integral part of sunlight. UVB can cause stresses or act as a developmental signal depending on its fluence levels. In plants, the mechanism by which high-fluence-rate UVB causes damages and activates DNA-repair systems has been extensively studied.
