The purpose of this study was to investigate the influence of transformational leadership by head teachers in Sotik Sub County and its relationship to teacher job satisfaction. This study was conceived after the realization that there had been increased cases of teacher attrition (transfers and resignation) in the past three years. For example, teachers’ transfers had been increasing by 5.2 percent annually while teachers resigning from their jobs had been on a steady increase. The objectives of the study were to establish the extent to which head teachers apply intellectual stimulation approaches and individualized consideration, on teachers’ job satisfaction in Sotik Sub County primary schools. The theoretical framework for this study was based on transformational leadership theory developed by Burns (1978) and elaborated by Bass (1985). The study adopted an ex post facto and descriptive survey research designs. The study was conducted in Sotik Sub County, Sotik County. The target population for the study comprised of 52 head teachers and 667 teachers employed by TSC. The sample size studied comprised of 16 head teachers who were purposively selected and 200 teachers who were selected using stratified and simple random sampling methods. The study collected data using revised MLQ and MSQ questionnaires by Bass and Avolio (1997). The research instruments were tested for validity and reliability prior to being used in the field. The data collected from the field was analyzed using mixed method approaches. Statistical Package for Social Sciences (SPSS Version 20) aided in data entry, coding and analysis of quantitative data from questionnaires. In presenting analysed quantitative data, descriptive statistics indicating frequency, percentages, means, and standard deviations were executed to analyze the data quantitatively while inferential statistics: multiple regression analysis and T-test correlation were used to check on the relationship between various transformational leadership strategies and teachers job satisfaction. For qualitative data, themes and sub-themes were used to classify data from interviews. Tables, graphs and pie charts were used for presentation of the analyzed data. The results of the study showed that 58.3% of teachers’ job satisfaction was explained by transformational leadership style exhibited by head teachers in public primary schools in Sotik Sub County. Correlation results on the independent variables showed that there was significant correlation (p<0.01) between; individualised consideration (r=0.613), and intellectual stimulation (r=0.735) and job satisfaction of teachers. The study recommends that head teachers should be role models, they need to be ensuring effective communication between them and teachers, they need to provide and articulate clear vision to teachers and support continuous professional development programmes for teachers in their schools. The study is significant to head teachers, teachers, school board of management, and Ministry of Education and future researchers.

This study was conducted to evaluation of different formulations of Betanal Progress OF herbicide on weeds control of sugar beet field. The experimental design was factorial on the basis of randomized complete block with four replications. Treatments consisted of four different formulations of the herbicide Betanal Progress F (Iranian, Spanish, German and Chinese) with four different doses (3, 4, 4.5 and 5 liters per hectare). Evaluated traits included frequency of weed and dry weight at 15 and 30 days after spraying. Result showed that German formulation and 4.5 liter per ha Betanal Progress F had highest weed control at sugar beet field.

In this paper, the new extended -expansion method is used for constructing the new exact traveling wave solutions of nonlinear evolution equations arising in mathematical physics namely, the (2+1)-dimensional modified Zakharov-Kuznetsov equation. As a result, the traveling wave solutions are expressed in terms of hyperbolic, trigonometric and rational functions. Moreover, these methods could be more effectively used to deal with higher dimensional and higher order nonlinear evolution equations which frequently arise in many scientific real time application fields. It is shown that the method provides a powerful mathematical tool for solving nonlinear wave equations in applied mathematics, mathematical physics and engineering problems.

This paper attempted to explore vocabulary learning strategy use by English Translation students. It also aimed at studying the participants’ level of creativity. Moreover, it attempted to investigate the relationship between students’ vocabulary learning strategy use and creativity. In addition, it tried to examine the impact of students’ level of education and gender on the relationship between their vocabulary learning strategy use and creativity. Sixty four English Translation students took part in the study. The vocabulary learning strategy questionnaire (Jones, 2006) was utilized to investigate the participants’ vocabulary learning strategy use. In order to measure their creativity level, Torrance test of creative thinking (Torrance, 1999) was administered. It was explored that dictionary and social strategies were reported as the most frequent strategies utilized by all students and study preferences were the least frequent ones. The result also showed that the participants displayed a low level of creativity. Their creativity level had no significant relationship with their vocabulary learning strategies except for the guessing strategies (r= .282, P< 0.05). Freshmen and seniors’ level of education did not affect the relationship between the two variables while junior students displayed a significant impact on the relationship between creativity and vocabulary learning strategy use with respect to guessing strategies. Finally, it was explored that gender affected their relationship with regard to guessing strategies and social strategies for females and males, respectively.
