Influence of Mental Harassment Ban on Student Discipline in Secondary Schools in Kenya: A Case Study of Ugenya, Gem and Siaya Sub-Counties
(Greener Journal of Educational Research, 2016)The Kenya government banned Mental Harassment in schools as stipulated in The Basic Education Act, 2013. This was as a result of the recommendations of the Task Force on Student Discipline and Unrests in Secondary Schools, ... -
RELATIONSHIP BETWEEN HUMAN RESOURCES AND STUDENTS’ PERFORMANCE IN KISUMU COUNTY
(International Journal of Education and Research, 2020)Primary schools exist to fulfill certain mandates that include offering quality education to learners, maximizing the stakeholders’ interest, social responsibility and ethics. However, the achievement of these mandates ... -
Exact analytical solutions for fully quantized parametric oscillation dynamics
(Routledge, 2013)In this paper, a simple method for obtaining general analytical solutions of the time evolution equations for a fully quantized parametric oscillation process is developed. Heisenberg’s equations for the signal–idler photon ... -
A Direct Calculation of First-Order Wave Function of Helium
(IOP Publishing, 2010)We develop a simple analytic calculation for the first order wave function of helium in a model in which nuclear charge screening is caused by repulsive coulomb interaction. The perturbation term, first-order correlation ... -
Generalized relativistic dynamics in a non-inertial reference frame
(Springer-Verlag, 2010)Generalized relativistic field equations have been derived for dynamics in a non-inertial reference frame interpreted as a Finsler space where events are specified by both spacetime coordinates and corresponding velocities ... -
Revisiting non-degenerate parametric down-conversion
