Study on classroom environment and achievement among rural school students

Academic institution  intended for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is commonly compulsory and classroom management is related to all teachers actions aimed to establish the simulative learning environment.  Classroom environment systems are effective because they increase student success by creating an orderly learning environment that enhances students' academic skills and competencies, as well as their social and emotional development. In these systems, students progress through a series of schools. Among other factors, empirical evidence has confirmed that school climate is powerful in affecting students' academic achievement. However, the extent to which both of student and staff perceptions of school climate influence student achievement. Furthermore, the precise psychological processes underpinning the climate-achievemen

Directed Connectivity Analysis of the Neuro-Cardio- and Respiratory Systems Reveals Novel Biomarkers of Susceptibility to SUDEP

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related mortality and its pathophysiological mechanisms remain unknown. We set to record and analyze for the first time concurrent electroencephalographic (EEG), electrocardiographic (ECG), and unrestrained whole-body plethysmographic (Pleth) signals from control (WT - wild type) and SUDEP-prone mice (KO- knockout Kcna1 animal model). Employing multivariate autoregressive models (MVAR) we measured all tri-organ effective directional interactions by the generalized partial directed coherence (GPDC) in the frequency domain over time (hours). When compared to the control (WT) animals, the SUDEP-prone (KO) animals exhibited (p \u3c 0.001) reduced afferent and efferent interactions between the heart and the brain over the full frequency spectrum (0-200Hz), enhanced efferent interactions from the brain to the lungs and from the heart to the lungs at high (\u3e90 Hz) frequencies (especially during periods with seizure activity), and decreased feedback from the lungs to the brain at low (\u3c40 Hz) frequencies. These results show that impairment in the afferent and efferent pathways in the holistic neuro-cardio-respiratory network could lead to SUDEP, and effective connectivity measures and their dynamics could serve as novel biomarkers of susceptibility to SUDEP and seizures respectively
