    Determinants of Adoption of Alternative Pest Management Practices in Cotton Farming: A Case Study from three Woreda’s of Arbaminch Zuria, Amibara and Gewane in Ethiopia
    (Addis Ababa University, 2021-10) Abebe, Tsegaye; Dirba, Dawit PhD
    The environmental and health risks of chemical pesticide application are usually becoming a serious global risk in agricultural fields like cotton farms. In recent studies despite the existence of chemical pesticide risk on environment and health issues, the engagement of farmers for the adoption of alternative practice to chemical pesticides is still imminent in the context of cotton farms in sub-Saharan Africa including Ethiopia. However, there are few studies on examining the determinants for adoption of alternative pest management practices (APMP) for the benefits of emission reduction from chemical pesticides pollution. Therefore, an alternative pest management practices (APMP) to chemical pesticides which constitutes both agronomic and cultural Control methods (ACCM) and biological control methods (BCM) is an essential strategy in the cotton crop protection strategies and other related environmental conservation areas. This research focused with a major objective of examining factors that can influence adoption of an alternative pest management practices to chemical pesticides application activities along with farmers perception and familiarity to such practices in three cotton growing areas of Amibara, Gewane and Arbaminch zuria districts in Ethiopia. The data for study was collected from 384 farmers, using structured and semi-structured questionnaire interviews and focused group discussions. Multistage random and purposive sampling technique was employed to select the required sample size. The descriptive analysis revealed that 23 % of the sample households were adopter and 77 % were nonadopters of these alternative strategies. A bivariate probit regression model was fitted to analyze the potential variables determining farmers’ adoption and the marginal effects of different variables in the study area. Among 12 explanatory variables employed in the model, only seven variable including training on APMP, risk aversion status of chemical pesticides, risk of adoption for the alternative practices, farm size, land tenure rights, distance from nearest market, and agro ecology/division were significantly influencing the adoption of both controlling methods(ACCM and BCM). In addition the variables age and education were marginally significant to only the practices of BCM whereas extension contact and share of income from cotton farming is only significant to the practice of ACCM. The study therefore recommends that policy makers and other related stakeholders should give more attention to those influencing factor on addressing the problems since reduction of environmental pollution can generates significant economic, health and environmental benefits to cotton farmers and the society as a whole.

    Philological and Textual Analysis of the Ethiopic Book of Amos
    (Addis Ababa,University, 2001-07) Abebe, Tsegaye; Alehegne, Mersha (PhD)
    This thesis focuses on the philological, comparative and textual analysis of the Ethiopic Book of Amos. Among the numerous Ge’ez manuscripts of the Book Amos, located with other prophetic books, the manuscript UNESCO 10.34 is worth studying. When one compares this manuscript with five other manuscripts, namely EMML 7584, Cambridge 1970, EMIP 01029, EMIP 01095 and UNESCO 10.04, one notices surprising phenomena. UNESCO 10.34 contains a considerable amount of unique readings, difficult to explain by scribal errors, by innovative readings. The interesting question would then be to try to explain the reason or reasons for such remarkable differences. One may not exclude here the probability of a Ge’ez translation from a Greek, Hebrew or Arabic text totally different from the one that used for the other five manuscripts. The full text of Ethiopic Amos according to the UNESCO 10.34 is displayed in chapter 2. In order to show the uniqueness of UNESCO 10.34, a table with six columns is prepared (Chapter 3). The types of differences are then presented in following chapters, as far as omissions, additions and substituttions are concerned. The research demonstrates the uniqueness of UNESCO 10.34, leading to need of further researches so as to ascertain the original language and text from which this interesting manuscript has emerged.

    A Project Report on Hausdorff Measure
    (Addis Ababa University, 2013-03) Abebe, Tsegaye; Goa, Mengistu (PhD)
    Measure Theory is the rigorous mathematical study of the field commonlyknown as Hausdorff measure.Hausdorff measures were introduced as certain lower dimensional measures on ℜwhich allow us to measure “small” subsets in ℜ. The Hausdorff measure and the associated Hausdorff dimension of the set provide a more delicate sense of the size of a set in ℜthan the Lebesguemeasure provides. In this work we study means of constructingHausdorff measures, via the so-called “outer measure” and “Carathéodory measure",which isolate certain small-scale features of complicated sets in a metric space. The construction is explicit andcovered in detail, after which specific instances of constructed measures areinvestigated in depth.

    Risk Perception of HIV/AIDS among Adult Population: The Case of Nazareth Tractor Assembling Factol'Y Workers
    (Addis Ababa University, 2009-01) Abebe, Tsegaye; Adugnh, Getachew (PhD)
    The putpose of this study was to investigate holY adult workers perceive their risk of HIV infection in relation to their sexual behavior in a setting of high HIV prevalence. To this end, a descriptive survey method was employed. The study employed both primmy and secondary data sources. The primmy sources of data were adult workers employed in Nazareth Tractor Assembling Factory. Three principal data collecting tools were employed, namely, questionnaire ,semi- structured interview and focus group discussion to access first hand data. The secondmy source of data were generated from pertinent government policy and strategic documents and also from literatures developed both nationally and internationally by prominent figures and institutions. A total of 170 adult workers in Nazareth Tractor Assembling FactolY, were used as respondents. Purposive sampling technique was used to select the interviewees and random sampling technique was used to select FGD respondents .. Data analysis was conducted using both descriptive and inferential statistics. In addition, bivariate analysis with Chi-square test was employed to see the relationship of the independent variables with the dependent variable. As a result the following major findings were obtained: 59.8% of the respondents knew that HIV is a virus, 21.3% have undergone VCT to know their status, 17.3% have ever used condom, more than 70% have involved in multiple sexual practices, and about 53.3% leveled themselves as higher risk perceivers due to variousfactors associated to their sexual behaviors. In addition, the bi-variate analysis has shown the existence of strong relationship between some of the independent variables (sex, VCT, alcohol consumption and multiple sexual partners) and dependent variable (risk perception of HIV/AIDS among adult populations). Based on major findings, conclusions were drawn and recommendations were forwarded somc of these include;: Sound and viable information, education and communication (lEC) and/or behavioral change communication (BCC) interventions should be initiated and jilrther strengthened by Nazareth Tractor Assembling FactOlY Management; VCT for H IV should be encouraged by productive sectors and supported by workplace specific jimctional HIV policy and the intervention in the world of work should necessarily consider adult education to impart an integrated and holistic knowledge; Concerted efforts of all the factOlY community are critically important to mitigate the spread and devastating impact of HIV/AIDS.
