Item Relationship between Employee Work Related Attitudes and Employee Performance: In the Case of Ethiopian Insurance Industry(Addis Ababa University, 2019-06) Tesfaye, Girma; Jemal, Mohammed (PhD)The aim of this study was to examine the relationship between employee work related attitudes and employee performance. The independent variable is employee work related attitudes consist with three sub variables namely; job satisfaction, organizational commitment and job involvement while employee performance was treated as a dependent variable. Accordingly, four research hypotheses were developed to address the research objectives. Explanatory research design was adopted with quantitative approach to examine the relationship among the study variables. Stratified random sampling procedure was applied. 360 questionnaires were distributed to employees, including managerial and supervisory staff, drawn from insurance companies, out of which 301 (83.6%) were successfully filled in and returned. Descriptive and Inferential statistics were applied and the major statistical tools used were frequency, percentage, mean, standard deviation, Pearson correlation and multiple regression analysis. The study found that job satisfaction, organizational commitment and job involvement are positively related with employee performance. The findings also showed that job satisfaction, organizational commitment and job involvement in aggregate explained 56.3% of variance in employee performance. Finally, recommendations were forwarded for insurance companies and at the end; the study identified and suggested areas for future research.Item Runoff and Sediment Yield Modeling in Laga Dadi Reservoir and its Watersheds(Addis Ababa University, 2021-07) Tesfaye, Girma; Bayou, Chane (PhD)Reservoir sedimentation is a serious moment of surface runoff and soil erosion with large environmental and economic implications. Deposition of sediment in reservoirs reduces the storage capacity of the reservoirs and affects the operation and stability of the dams. The main objective of this study is to assess runoff & sediment yield at Laga Dadi reservoir and its catchment and identify hotspot areas of the watershed in runoff & sediment yield. The outlined objective is attained by a physical based hydrological model Soil and Water Assessment Tool (SWAT). Daily runoff and sediment data from 1994-2009 were used in this study. Data from 1994-2003 were used for calibration and 2004-2009 for validation. Following the successful calibration and validation of the model on the study area, runoff and sediment yield have been estimated. The annual runoff volume generated on the watershed was estimated to be 654.5 mm as it is known that SWAT Generate Runoff in mm. The total simulated mean annual Sediment yield loading from Laga Dadi watershed simulated is 6.73 ton/ha/yr. The total mean annual sediment yield that is drawn from Laga Dadi watershed predicted by SWAT model is found to be 138146.71 tons. The model prediction verified that about 17% of the watershed around the dam site has erosion potential area contributing very high sediment yield exceeding the tolerance limit. Hence, the researcher recommends conservation and environmental protection in upper catchments, tributary rivers site and on the spot, area shall be done continuously.Item Sexual Behavior and Risk Perception of HIV Infection Among Young Adults in Dessie Town(Addis Ababa University, 2008-06) Tesfaye, Girma; Hailemariam, Assefa (PhD)Available studies indica!e !ha!, sometimes people do not perceive !heir risk of HIV adequa!ely and !herefore, they are less motivated to protect themselves and others from HIV infection. In Dessie town, as in many other Ethiopian towns, city and other settings of the world, the sexual behaviors and self assessment of the risk of HIV infection of the current cohort of young people will strongly influence the course of HIVIAIDS The purpose of this study is to identifY the socio-economic and behavioral factors that affect risk perception of HIV infection among young adults in the age 15- 29 years. Method: This study is a cross-sectional survey research that was conducted in Amhara Region, Dessie town form15 February to 15 March 2008. A total of 721 youths in the age group 15-29 were selected using cluster sampling method followed by simple random sampling method. A self-administered structured questionnaire, FGDs and interview with key informants were used to collect the required data from the study participants. The data were edited, coded entered, cleaned and analyzed using descriptive statistics and multivariate analysis with SPSs. Results show that about half of the study participants are sexually experienced. Of these, 55.6% had sex with one partner only, abou! a quarter used condoms consistently and about 19% had multiple sexual partners and did not use condom. Nearly 12% of the sexually active participants had ever contracted at least one STis. Overall, 7% of males and 11.5% offemales perceived high risk of HIV infection; and 12% of male and 15.8% of female respondents perceive themselves to have a moderate chance of gelling HIV In general, female respondents were considerably more likely than males to report themselves at a higher risk of HIV infection. Sex, exposure to media, religiosity, age at first sex, the number of life time partners, age difference between partners, condom use, taking HIV test, are found to be the predictors of risk perception of HIV infection among young adults in Dessie town. Conclusions: The findings of this study provide justification for intervention targeting on key factors that influence the risk perception of HIV infection. Providing the necessary information in a way that could bring about behavioral change among the young adults is recommended.Item Sexual Behavior and Risk Perception of HIV Infection Among Young Adults in Dessie Town(Addis Ababa University, 2008-06) Tesfaye, Girma; Hailemariam, Assefa (PhD)Available studies indicate that, sometimes people do not perceive their risk of HIV adequately and therefore, they are less motivated to protect themselves and others from HIV infection.
