    Assessment of the Abuse of Ethiopian Women Migrant Workers in Saudi Arabia
    (Addis Ababa University, 2016-05) Hunde, Sintayehu; Abebe, Dechasa(PhD)
    Women migrant workers claim a significant component of the labor force in the Arab labor market. Over the past few years, the Plight of migrant workers has been reported in the Gulf due to the persistent exploitation and abuse of their rights. The purpose of this study is to highlight the sources of the predicaments Ethiopian Women migrant workers are facing in the Kingdom of Saudi Arabia. These problems include; forced long working hours of up to 20 hours a day; seven days a week, unpaid wages and salaries, physical violence, rape, crime and other forms of exploitation. The international division of labor proposes that the reproduction activities have been progressively commodity in the context of the global market economy. As such our study uses in depth interviews and questionnaires to investigate and enumerate the root causes that contributing the abuse of Ethiopian women migrant workers in Saudi Arabia. The scope of this thesis is limited to women Saudi returnees who are engaged in small scale enterprises through Addis Ababa Bureau of Labor and Social Affairs those returnee workers who use both illegal and legal means of recruitment process through PEAs. In addition, the approach of this study is narrowed down to focusing on abuse, exploitation, trends and practices of migrant workers in the Gulf Countries, particularly in Saudi Arabia. The themes of the result from interviews and questioner are discussed with relevant theoretical explanations provided in the research study

    Investigation of Influence of Compaction onThe Stabilityof Earthfill Dams of Tropical Soils
    (Addis Ababa University, 2003-11) Hunde, Sintayehu; Boled, Girma(PhD)
    Dam construction is one of the major civil engineering activities, which enhance development. If the construction of such infrastructures can be achieved within sound technical and affordable financial capacity, then it is possible to realize the dream for development and well-to-do life. One of the merits of earth fill dams is that they can be constructed from locally available natural material (soil) within sound technical and affordable financial capacity. For soils of a given locality to be used safely and economically, appropriate methods of determining the geotechnical properties and shear strength parameters have to be investigated and developed. In addition to this, the appropriate methods of compacting locally available tropical soils have to be developed. Accordingly, in this paper the influence of compaction on the stability of small earth fill dams of local tropical soils has been investigated. In addition to this, some peculiar geotechnical and geo-chemical characteristics of local tropical soils that have been used in construction of earth fill dams have been studied. Accordingly, the fill material of the cofferdam of Gilgel Gibe Hydroelectric Project has been obtained to be true laterite, while the core material of Dire Dam and the red clay soil of Addis Ababa (Semen Gebeya Area) have been obtained to be lateritic. The soil samples were compacted at optimum moisture content, at drier of the optimum moisture content and at wetter of the optimum moisture contents. Then, triaxial tests were done on the soil samples to investigate the variation in shear strength properties of these soils, which ultimately affect the stability of the earth fill dams. Compaction moisture has been obtained to influence the stability of earth fill dams. Samples compacted on the drier side of optimum moistures registered high shear strengths. But these strengths were observed to be lost upon further increasing the compaction moisture and also upon sample saturation. Variation of permeability of compacted soils with respect to compaction moistures and also the effect of saturation settlements were investigated. Accordingly, Permeability has been obtained to decrease towards the optimum moisture content. On the drier and wetter sides of the optimum, higher values of coefficients of permeability have been obtained. vi The problem of saturation settlement has been observed to occur when the soil is compacted on the drier side of the optimum moisture.
