Principals’ Management Styles and Students’ Unrest in Public Secondary Schools in Nairobi County, Kenya

This paper is just a sample template1* for the prospective authors of IISTE Over the decades, the concepts of holons and holonic systems have been adopted in many research fields, but they are scarcely attempted on labour planning. A literature gap exists, thus motivating the author to come up with a holonic model that uses exponential smoothing to forecast some quantitative The nature of students’ unrest in schools has taken a dramatic turn for the worse. These findings are based on a study conducted in 2009.The study sought to establish the management styles used by principals and their influence on students’ unrest in public secondary schools in Nairobi County.A descriptive research design was used. A sample of 15 principles, 60 class teachers and 600 students were selected using stratified, simple random and purposive sampling methods. Data were collected using questionnaires and interview guide. Inferential and descriptive statistics were used to analyze data. The studyfindings were that, there was no clear management style that was predominant in the schools surveyed. The findings also showed that;mock exams, diet, bullying, high handedness of principals, pressure from other schools, transfer of principals, lack of communication between students and the principals, poor facilities, and drug and substance abuse were common causes of students unrest. All the respondents indicated that; principal’s management style influences student’s unrest in secondary schools. Head teachers’ gender, qualifications, experience and age also influenced unrest in secondary schools. The study concludes that; principals use various styles in managing schools. The study recommends that school administrations need to enhance communication among various stakeholders in the school through dialogue.

Exploring the Potential of A Highly Compressible Microcrystalline Cellulose as Novel Tabletting Excipient in the Compaction of Extended-Release Coated Pellets Containing an Extremely Water-Soluble Model Drug

Compaction of controlled-release coated pellets into tablets is challenging because of the fusion of pellets and the rupturing of coated film. The difficulty in compaction intensifies with the use of extremely water-soluble drugs. Therefore, the present study was conducted to prepare and compact pellets containing pseudoephedrine hydrochloride as an extremely water-soluble model drug. The pellets were produced using an extrusion–spheronization technique. The drug-loaded pellets were coated to extend the drug release up to 12-h employing various polymers, and then they were compressed into tablets using microcrystalline cellulose Ceolus KG-801 as a novel tabletting excipient. The in vitro drug release studies of coated pellets and tablets were undertaken using the USP basket method in dissolution test apparatus I. The amount of drug released was analyzed at a wavelength of 215 nm. The combined coatings of hydroxypropyl methylcellulose and Kollicoat SR-30D yielded 12-h extended-release pellets with drug release independent of pH of dissolution medium following zero-order kinetics. The drug release from the tablets prepared using inert Celous KG-801 granules as tabletting excipient was found faster than that of coated pellets. However, a modification in drug release rate occurred with the incorporation of inert Ceolus KG-801 pellets. The drug dissolution profile from tablets containing 40% w/w each of coated pellets and inert granules along with 20% w/w inert pellets was found to be closely similar to that of coated pellets. Furthermore, the friability, tensile strength, and disintegration time of the tablets were within the USP specifications
