Given the important role that education plays in the society, coupled with the dynamic nature of the education sector there has been an increased social pressure on the education system in general and school administrators in particular.

The sample was selected through stratified technique sampling by age sets, and by gender. The sample that was drawn from the above accessible population was 260 respondents whose distribution was 160 females and 100 males. The instrument for data collection was Focused Group Discussions that yielded valuable information from the targeted participants. The statistical analysis was done using the latest Statistical Package for S...

As a social problem, it has adverse effects on the girls’ academic performance, and career development as it results in girls dropping out of school and some are forced to early marriages. Despite efforts to prevent girls dropping out of school due to pregnancies, there is still evidence of high prevalence of pregnancy among girls in secondary schools. This study therefore sought to establish social, cultural and economic causes of secondary school girls’ pregnancies: Implication for counseling in Pokot South Sub County of West Pokot County, Kenya.

Global trends indicate that disaster-induced displacement is on the rise, and is brought about by factors which include natural and human-made disasters as well as complex human conflicts. The most notable case of internal displacement in Kenya arose from the 2007-2008 post-election violence. Most of the displacees have been since resettled. Among the effects of displacement are loss of property, loss of livelihoods and mental health problems. The aim of this study was to establish the vulnerability to mental health problems among persons in prolonged displacement in Nakuru County of Kenya. The study was a qualitative survey in which a sample of 400 respondents was obtained from a population of 106,004 internally displaced persons who had been resettled. Data was collected using questionnaires and structured interview schedules. The mental health status was determined using an adapted version of the Impact of Event Scal...

The sample of 1370 children between the ages of six and ten years was gathered in the primary schools of the Municipality of Nakuru, a region representative of the overall population of Kenya. Percentile scores for boys and girls by age group were generated. Demographic and academic information on participants was gathered using a teacher questionnaire. Test-retest reliability for the instrument was established by re-administering the Raven's to a randomly selected subsample of 50 children at a two week interval. Internal consistency reliability was generated using Cronbach's alpha. Using the current data, the RCPM appears to be a reliable and valid instrument for use in screening Kenyan children.

(Fagaceae), removed in 2002–2007 from three sites within the Ozark National Forest, Arkansas, to investigate the relationship between vascular tissue N status and wood borer infestation. Populations of native red oak borer, Enaphalodes rufulus (Haldeman) (Coleoptera: Cerambycidae), experienced an outbreak and population crash during the sampling period. Vascular tissue N was not correlated with borer infestation density (exit holes/m−2/bark surface), which suggests variation in N status of vascular tissue was not influenced by or did not influence borer success. Vascular tissue N was greater in trees sampled during winter months than in trees sampled in spring and summer months.
