    (Addis Ababa University, 2007-07) Addis, Zelalem; Meshesha, Ayele (PhD)
    The purpose of this study was to examme the effects of Perceived Organizational Support, Participation m Decision-making, Extra Role Involvement, Teaching Experience, and Feelings of Professional Community on Professional Commitment of teachers' teaching in West Gojjam Zone high schools. In developing the instruments, Cronbach's alpha reliability for each scale and item total correlations for each items were computed for pilot and alpha coefficient again for the main study. 135 randomly selected teachers and 7 principals of each from 7 randomly selected schools of the Zone were used as the sample of the study. The data were gathered with 59 close-ended items and with some open-ended questions for teachers and with semi structured interview for school principals. Pearson product moment correlation, analysis of variance (ANOVA), multiple and stepwise regression analysis were used to analyze the data. The result revealed that professional commitment was positively and significantly correlated with participation in decision-making (r=.625, p<.Ol), perceived organizational support{r=.594, p<.Ol), feelings of professional community (r=. 517, p<.Ol), extra role involvement (r=.449, p<.Ol), and year of teaching experience{r=.216, p<.05). All the independent variables together contributed 44.7% {F (5. J29) =20.848, P<.OOl) to the variability in teachers' professional commitment. Participation in decision-making being the major predictor explained 39.4% (F (1,J33) =86.476, P<.OOl); extra role involvement and perceived organizational support were the second and third major predictors, respectively. The above three variables together explained about 43.9% (F(3,J3J)=34.174, P,<.OOl) of the variability. The rest two independent variables were not significant predictors of teachers' professional commitment. Hence, this study would help educational leaders, professionals, and school principals in their effort of enhancing and maintaining high school teachers' professional commitment.

    Identifying & Validating Dimensions of Service Quality for the Ethiopian Hotel Industry
    (Addis Ababa University, 2015-05) Addis, Zelalem; Takele, Yitbarek (PhD)
    Quality service has become a serious issue among scholars in the hotel industry. This arises due to the fact that operators of the industry still find it difficult to understand what customer needs are at a particular time. The purpose of this study is to identify and validate dimensions of service quality for the Ethiopian hotel industry. The study used HOLSER, Gronroos’s and Loading Quality Index and four additional dimensions added by the researcher which are room amenities, food and amenities, physical facility and price. As a foundation for questionnaire development each model and additional dimension was used. However, the items were deducted and modified after conducting pilot study to suit to the specific features of a hotel setting. The study was conducted in Addis Ababa with the participation of four star hotels because they are found abundantly and easily accessible. A total of 380 questionnaires were administered to twenty four star hotel customers out of whom 270 questionnaires were returned and used for a comprehensive empirical analysis. Inferential statistics have been used to test hypothesis and to investigate research problems and questions. It was identified that the eight dimensions are found critical to measure hotel service quality. The result of correlation analysis revealed that all service quality dimensions are correlated with overall service quality. From the regression result it has been found that all service quality dimensions have positive significant impact on service quality. Moreover, managers have moderate perception toward service quality dimensions also hotels don’t have standardized service quality measurements. Thus, hotel operators must continuously provide more interactive service standards by using service quality dimensions as measuring service quality for hotel service
