    An Ecological Study of Biteyu Forest, Gurage Zone, Southern Nations, Nationalities Peoples Region
    (Addis Ababa University, 2003-06) Biru, Mekonnen; woldu, Zerihun (PhD); Demissew, Sebsebe (Professor)
    Biteyu Forest is located at the edge of the western escarpment of the Gurage mountain chain. This forest is probably one of the forest patches that were once widespread on the central plateaux of Shewa. In this study vegetation composition of the forest following altitudinal gradients was performed. Sixty, 20 m x 20 m quadrats were selected and all the plants in the quadrats were recorded. Cover abundance value of all the species was estimated. The vegetation data was analyzed using the program SYNTAX (Podani, 1998) to identify the community types. Six community types were identified and named after two or three dominant species. Shannon-Wiener diversity index were computed to measure species diversity in a comunity. One-way analysis of Variance (ANOVA) was used to test the difference in communities in relation to environmental parameters along the altitudinal gradient including soil properties (pH, texture and electrical conductivity), altitude, slope and aspect. Height and DBH of the woody species in all the quadrats were taken. 177 species belonging to 143 genera and 68 families were identified. Shannon-Wiener diversity index revealed that species diversity is high in communities 1, 4 and 2 respectively. This is probably due to high rate of disturbance in the communities. Statistical analysis (ANOVA) have shown that the difference in communities might partly be explained by the variation in altitude, slope and soil properties at p< 0.05 level of significance with the exception of aspect and silt. Height and DBH class measurement indicated that most of the woody species in the forest are confined in the lowest class distribution. Søresen’s similarity coefficient showed the similarity of the forest with Menagesha-Suba forest in floristic composition.

    Factors Affecting Academic Achievement of Evening Program Female Students in Addis Ababa City Administration
    (Addis Ababa Univerisity, 2013-01) Biru, Mekonnen; Chalchisa, Desalegn(PhD)
    The main purpose of this study was to examine level of academic achievement and factors affecting the academic achievement of 2nd cycle primary school evening program female students in Addis Ababa City Administration. This survey study was carried in four government and non government primary schools employing multi stage sampling. Quantitative and qualitative research methods were employed in scrutinizing the problem. Documents, questionnaires, interview and group discussions were employed to collect multi-dimension data. Quantitative data were analyzed primarily through employing descriptive statistics like percentage, mean and standard deviation and inferential statistics like t-test. The qualitative data that were collected through interviews, group discussions and open-ended questions, were examined through coding, categorization and thematic analysis. The findings of the study show that female students academically perform less when compared to their counterpart male students in both class and primary school leaving examination. The achievement of students in class examination and Primary School Leaving Examination showed immense differenceshigh in the former and very low in the latter. Among the potential variables identified, both quantitative and qualitative data verified that students and teachers behaviors highly contributed for female students' low achievement and followed by socio-economic, school and social characteristics. To overcome the problem and enhance the academic achievement of evening program female student, paying due attention for evening program education in general and for female students is crucially important. Implementation of direction for evening program education, close-up supervision and support, motivating teachers who involved in this program, developing students selfconcept, improving the awareness of the society on the importance of evening education in supplementing the regular education system is paramount important.
