    (Addis Ababa University, 2006-07) Kedir, Mohammed; Kassaye, Woube (PhD)
    The maIO purpose of thi s s tud y is to identify and explore th e mealllngs of folkl or ic contents included in second cycle primary Oromo langua ge te xtbooks to be tau g ht as integral part of the four language s kills. The method e mplo yed to ana lyze and interpret tb e folkloric contents was qualitati ve content analysi s. The folkloric contents found in the texts; the curriculum developers; teacher educators and second cycle primary te ac hers, were the sources of information that had been ana lyzed and interpreted. Apparently th e se mi structured interview guide and open end ed questionnaires were used as a supporti ve data co ll e ction in struments. All of the folkloric contents found in the texts were purposively analyzed and interpreted und er this stud y. According to the major findings the entire passages found in the texts were ninet y nin e. Among these fifteen passages conta in e d folkloric contents. From the four forms of folklore; oral literature and performing folk arts are found in the texts. Between the se th e oral literature genres are dominantl y portra ye d. The re st forms s uch as : soc ial fo lk custom and material culture are not reflected in the texts. From oral literature genres: eleven folk tale s, thirty s ix proverbs , and twenty five riddles were found in the te xts. They were to be learned in a ll grades except seventh g ra de. In seventh grade th e only ora l literature genre to be lea rned is folktale . Among folk ali genres : one pa storal song, two love songs, and one chi ldren play grou nd rhyme were found in the texts . They were to be learned in grade five and grade e igbt. Tbe identified genres (types) of oral literature and performin g folk arts are five and the item s of th ese genres were totally seventy six in number. If not some, the folkloric contents designed in the syllabu ses are linked to the texts developed. With regard to the main recommendations, ex ploring prior to selecting folkloric contents and selecti ng genres from all forms of folklore or folk life studies is advi sable . Tbe careful linkage of folkloric contents between the syllabuses and textbooks is an imp o rta nt p e rformance in cutTicu lum development. The vertical and hori zo ntal organi zation of so me folklori c contents n eed s assess m e nt. With re sp ect to teacher education ba sed on fo lklori c contents, conductin g another re search is re commended .

    Magnetic Field Evolution of Millisecond Pulsars Beyond the X-Ray death Line
    (Addis Ababa University, 2005-07) Kedir, Mohammed; Kebede, Legesse VV (PhD)
    Under the relativistic plasma diffusion theory (Kebede, 2002, 1996), we investigate the magnetic field evolution of millisecond pulsars beyond the X-ray death line by taking the competitive nature of magnetic field revival due to mass accretion and its decay due to one of the cooling sources called photon emission leading to pulsar field evolution at about threshold magnetic field for X-ray productions into account. Our study shows that the magnetic field is no more monotonous for old pulsars. This evolution of the magnetic field is applied to address the issue of the 35 day cycle of X-ray radiations of Hercules X-l
