Influence of fringe benefits on employee performance in large commercial banks in Nairobi city county in Kenya
(Journal of Strategic Management, 2018)Fringe benefits have been recognized as a way that motivate employees to increase their work output above the expected, therefore increasing employee performance. Fringe benefits are types of non-wage compensation provided ... -
Influence of nitrogen and spacing on growth and yield of chia (Salvia hispanica) in Meru county, Kenya
(Meru University of Science and Technology, 2022-06)Chia (Salvia hispanica L.) is an emerging food crop in Kenya and has attracted a lot of attention due to its edible seeds and leaves. Despite its importance, Chia production is still very low due to scarce information on ... -
The influence of oxygen partial pressure on material properties of Eu3+-doped Y2O2S thin film deposited by Pulsed Laser Deposition.
(Elsevier B.V., 2015)Eu3+-doping has been of interest to improve the luminescent characteristics of thin-film phosphors. Y2O2S:Eu3+ films have been grown on Si (100) substrates by using a Pulsed Laser Deposition technique.The thin films grown ... -
Influence of recognition schemes on employee performance in large commercial banks in Nairobi city county in Kenya.
(Journal of Human Resource & Leadership, 2018)Recognizing excellent performance openly builds motivation within the entire organization. It is acknowledged that employee recognition has contagious effects. When an employee witnesses others being rewarded for good ... -
Influences of Ga Doping on Crystal Structure and Polarimetric Pattern of SHG in ZnO Nanofilms
(Nanomaterials, 2019-06-21)The second-harmonic generation (SHG) in gallium doped ZnO (GZO) nanofilms was studied. The Ga doping in GZO nanofilms influenced the crystal structure of the films, which affected SHG characteristics of the nanofilms. ... -
Influences of Ga doping on crystal structure and polarimetric pattern of SHG in ZnO nanofilms
