The Power of Afaan Oromo as a Device for Explaining Africa’s Prehistory: An Africology Perspective
Creators: name: Tadesse, Dereje
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2020

description: Adopting an Africology and evolutionary linguistics perspective, this study shall exploit classical and contemporary archives and explores the linguistic, epistemological, theological and relational power of Afaan Oromo in explaining Africa‘s pre-history. In so doing, this paper explains away the colonial historians and their students who usually begin Oromo history only from 16th century. Early Egyptologists first studied Afaan Oromo in order to understand Ancient Kemet or Egyptian hieroglyphics and texts. Similarly, early Assyriologists studied Afaan Oromo and Oromo culture in order to decipherer Babylonian cuneiform texts. Moreover, comparative theologians used Afaan Oromo and culture to understand the origin of major religions of the world. Early African travelers, too, were convinced that Afaan Oromo was not only the lingua franca of Africa up until 19th century CE, but was possibly the language of the Ancient Egyptian, Ancient Nile Valley or possibly even of Hittite from which was Indo-European languages emerged as offshoot. This paper contributes significant substantive and historical implications that are highlighted for researchers who want to use Oromo language and institutional themes as a launching pad to study African prehistory.

description: Past holographic screens are codimension-one surfaces of indefinite signature that are foliated by marginally anti-trapped surfaces called leaves. Future holographic screens are defined similarly except with marginally trapped leaves. Bousso and Engelhardt recently showed that the leaves of past and future holographic screens have monotonic area. We prove a stronger area law that shows that subregions of leaves also have monotonic area. For every past and future holographic screen, there exists a family of leaf-orthogonal curves called the fibration of the screen. Any region in a leaf can be translated along the fibration to a leaf of larger area. Our result states that the area of the subregion grows as it is translated.

description: The rapidity distributions of $J/ψ$ mesons produced in proton-lead ($p$-Pb) collisions at center-of-mass energy per nucleon pair $\sqrt{s_{NN}}=5$ TeV are studied by using a multisource thermal model and compared with the experimental data of the LHCb and ALICE Collaborations. Correspondingly, the pseudorapidity distributions are accurately obtained from the parameters extracted from the rapidity distributions. At the same time, the transverse momentum distributions in the same experiments are described by the simplest Erlang distribution which is the folding result of two exponential distributions which are contributed by the target and projectile partons respectively.

description: The flash point (FP) modeling of ternary mixtures containing partially miscible regions, even by known models, is still challenging. This work proposes a practical and easy-to-use hybrid machine learning method, which combines artificial neural networks (ANNs) with the genetic algorithm (GA), to calculate the FPs of complex alcohol-based mixtures, particularly aqueous solutions of low-carbon alcohols. For this purpose, multilayer perceptron (MLP), radial basis function (RBF), and group method of data handling (GMDH) ANNs, were trained using the FPs of totally miscible region while the FPs of the partially miscible region were predicted by the trained ANN. By applying this approach, the FPs of partially miscible region of water-ethanol-1-butanol, water-ethanol-2-butanol, water-1-butanol-2-butanol, and methanol + toluene + 2,2,4-trimethylpentane were predicted. Another method was implemented by which the FPs of water-1-butanol-2-butanol mixture were predicted by only those of other mixtures, i.e., water-ethanol-1-butanol and water-ethanol-2-butanol. To the best of our knowledge, two applied approaches have not been previously used. Moreover, the FPs of two totally miscible aqueous solutions, namely water-methanol-ethanol and water-ethanol-isopropanol, were evaluated by different proposed ANNs in a usual way. The highest and lowest absolute average errors obtained by the applied methods for testing data were 5.09 and 0.45 °C, respectively.

description: This research was aimed at investigating challenges and prospects in the implementation of external communication strategies. A descriptive survey design and both primary and secondary sources of data were used for the study. Key Informant Interview (KII) and Focus Group Discussion (FGD) helped to gather data. The key informant interviewees and the FGD discussants were selected purposively. Focus group discussions were held with Mana woreda farmers‟ group. The researchers also used document review which were only used in 2013/14 and 2014/15 (GC). As part of the data analysis, content analysis was employed. The findings of this study revealed that the types of external communication strategies used by the research center ranges from booklets to TV. Regarding appropriateness, printed types of communication tools were the appropriate tools than the non-printed. The challenges encountered in the implementation of external communication strategies of JARC were human resources and staffing, policy and structure, management and technical networking, partnership and collaboration. In addition, the result revealed that the prospects of those external communication strategies exercised by the research center were radio and television. Finally, the recommendations were there should be a comprehensive, holistic and well defined policy provision or communication strategy guideline that could dictate and direct the communication work. Instead of the printed communication items used by the center, billboards, banners, and posters (both fixed and movable ones) could be possibly more accessible to the wider community as long as these are posted where many could have access to vividly see them.

description: To meet the surging demand of increasing mobile Internet traffic from diverse applications while maintaining moderate energy cost, the radio access network (RAN) of cellular systems needs to take a green path into the future, and the key lies in providing elastic service to dynamic traffic demands. To achieve this, it is time to rethink RAN architectures and expect breakthroughs. In this article, we review the state-of-art literature which aims to renovate RANs from the perspectives of control-traffic decoupled air interface, cloud-based RANs, and software-defined RANs. We then propose a software-defined hyper-cellular architecture (SDHCA) that identifies a feasible way of integrating the above three trends to enable green and elastic wireless access. We further present key enabling technologies to realize SDHCA, including separation of the air interface, green base station operations, and base station functions virtualization, followed by our hardware testbed for SDHCA. Besides, we summarize several future research issues worth investigating.

description: The purpose of this study was to examine the existing practices and challenges of Education Management Information System in Public Educational Institutions of Eastern Ethiopia. Survey research design that involves both quantitative and qualitative data was employed. Questionnaire and key informant interview were the methods used to collect data. The participants of the study comprised 15 university and college deans, 54 zonal education bureaus (ZEBs), regional education bureaus (REBs) and districts education bureaus (WEBs), 46 teachers, and 10 educational experts (with the total of n =125) were selected via purposive, simple random and stratified sampling techniques. The questionnaire was distributed to a total of 115 participants of the study, and 106 (92.2%) were appropriately filled in and returned. Additionally, 10 educational experts were interviewed. Data were analyzed using descriptive statistics such as frequency, percentage, mean and standard deviation. The obtained results showed that the current practices of educational management information system are below the expected level due to lack of qualified and well-trained professionals in the field. In addition, educational management information system positions in many educational institutions were dominated by those who do not have educational management information system qualifications, and even some educational institutions did not have education management information system experts at all. Thus, this has had a serious impact on collecting quality data, disseminating and managing information in educational institutions due to shortage of qualified personnel in the field of the study.

description: This paper presents an experimental study focusing on the effect of intake pipe blockage on the critical submergence of lateral dual square intakes under perpendicular uniform approach flow. The pipe blockage is implemented by various intake protrusions into the approach flow, with one of the intakes always kept flush with the channel sidewall. An increase in protrusion of downstream intake alone causes a significant decrease in critical submergence, and an increased protrusion of upstream intake alone causes higher critical submergence when both intakes operate under identical conditions. At higher protrusions of twice the intake size, the mutual influence between the intakes was negligible with multiple vortex formations at both intakes in dual configuration. Based on the results, an empirical equation is proposed for the computation of critical submergence for lateral dual protruded intakes and was found to be in good agreement with the experimental results, which will be useful in the design for fixing the invert level of dual intakes under approach flow condition. The flow blockage due to protrusion can be adopted effectively to reduce the critical submergence for multiple intake structures.

description: Mass models of galactic disks traditionally rely on axisymmetric density and rotation curves, paradoxically acting as if their most remarkable asymmetric features, such as lopsidedness or spiral arms, were not important. In this article, we relax the axisymmetry approximation and introduce a methodology that derives 3D gravitational potentials of disk-like objects and robustly estimates the impacts of asymmetries on circular velocities in the disk midplane. Mass distribution models can then be directly fitted to asymmetric line-of-sight velocity fields. Applied to the grand-design spiral M99, the new strategy shows that circular velocities are highly nonuniform, particularly in the inner disk of the galaxy, as a natural response to the perturbed gravitational potential of luminous matter. A cuspy inner density profile of dark matter is found in M99, in the usual case where luminous and dark matter share the same center. The impact of the velocity nonuniformity is to make the inner profile less steep, although the density remains cuspy. On another hand, a model where the halo is core dominated and shifted by 2.2-2.5 kpc from the luminous mass center is more appropriate to explain most of the kinematical lopsidedness evidenced in the velocity field of M99. However, the gravitational potential of luminous baryons is not asymmetric enough to explain the kinematical lopsidedness of the innermost regions, irrespective of the density shape of dark matter. This discrepancy points out the necessity of an additional dynamical process in these regions: possibly a lopsided distribution of dark matter.

Factors Affecting Housing Adequacy and Accessibility in Harar City, Harari Regional State, Ethiopia
Creators: name: Wakuma, Abenezer
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2020

description: Adequate and accessible housings are among the essential features of housing components. In most cities of developing countries, considerable emphasis was placed on the construction of housing units that does not fully consider adequacy and accessibility. This study examined factors affecting housing adequacy and accessibility in Harar city using descriptive and explanatory research designs. The theoretical bases of this study are theory of housing adjustment and the right to the city. A total sample of 275 respondents were randomly selected from six condominium housing sites. Data were analysed using descriptive statistics, ANOVA, and binary logistic regression model. The mean adequacy score obtained from all of the housing attributes revealed that there is inadequate housing. The most important housing attributes with significant influence on residents’ perception of housing adequacy are services, facilities, and quality management. However, there is no variation in perception based on respondents’ sex, age, marital status, family size, education level, and monthly income difference. The housing sites were not accessible to adequate and qualified schools, transport terminals, health centres, and market centres. Majority of the respondents which comprised 72% and 71.3% believed that the housing sites are inadequate and inaccessible, respectively. A decrease in the accessibility of housing sites is associated with decreasing number and quality of infrastructural and social services. In conclusion, this study provided a holistic picture of housing adequacy and accessibility, and associated factors. It can aid policy makers to revisit and implement a housing policy that consider adequacy and accessibility to upsurge residents’ satisfaction.

Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2019

description: Riddles in Oromo are among the children’s oral traditions that serve as the bearers of virtuous behaviors in their society. They contribute, by way of entertaining, to the proper growth and development of children which nurture them to be active and creative constituents of their society. Nevertheless, riddle got very low attention and little is being done to ensure that this genre of oral literature is preserved as part of long-living indigenous education system. This research aimed to document Oromo riddles with their underlined and diverse human experiences, knowledge, artistic expression, creativities, philosophical thoughts, linguistic features and imaginations of the society. Available and purposive sampling methods, structured and non-structured interview, both participatory and non-participatory observations, focus group discussion, and text collection were used to gather data, which were analyzed qualitatively. The fundamental procedures of riddles have been described as they are used in contextual settings. Thematically, their elements, social values, artistic thinking, and experiences of the society, philosophical thoughts and linguistic features have critically been examined. And results are found to indicate riddles in Oromo carry moral value and wisdom which are reliable and relevant to the children’s development and nurture them to be active and creative members of the society. The researchers, thus, recommend that relevant stakeholders need to come and act together to document, sustain and enhance the values of Oromo riddles.

Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2019

description: Researches reveal that women living on the streets are less likely to benefit from basic reproductive health services as living in the poorest segment of the society. The present research was meant to assess vulnerability to reproductive health risks among on-street women in Shashemene town. A cross-sectional study which involves both quantitative and qualitative design was used. A total of 163 on-street women, selected on the basis of purposive sampling procedure, have participated in the study. Both qualitative and quantitative data were collected using survey, non-participant observation and in-depth interview methods. While quantifiable data were entered into SPSS version 20 for further descriptive and inferential analysis, qualitative data were transcribed, organized, and narrated based on recurring themes in the data. The prevalence of rape and abortion was found to be low (11.5% & 9.45%, respectively). Awareness about HIV/AIDS and its way of transmission is very high, with a fascinating experience of undergoing voluntary testing and counseling. Correlation statistics have shown that patterns of undertaking voluntary testing and counseling was significantly associated to marital status (.186, P<0.05), educational status (-.183, P<0.05), and the number of children a woman gave birth to (.204, P<0.05). In relation to shelter and their overall living conditions, on-street women in the study area were found to be highly vulnerable to reproductive health risks. Hence, psycho-social support, including the provision of reproductive health services to the target group, deserves a serious attention.

Year: 2019

description: The purpose of this study was to examine practices of parental involvement in the education of their children with disabilities in inclusive government primary schools. Qualitative case study design was used to investigate the problem. A sample of six parents of children with disabilities and two teachers were selected using purposive sampling technique. Data was collected using a semi-structured interview guide and analyzed thematically based on Epstein’s (2001) framework of parental involvement with six dimensions. Results indicate that parents of children with disabilities involved better in parenting activities to support the education of children with disabilities. However, communication of parents with teachers and school principals was found to be minimal. They did not visit the schools regularly and discuss with school teachers and principals on their children’s learning. In addition, while few parents of children with disabilities provided learning support for their children at home; most parents of children with disabilities were unable to do so due to time constraints, wrong perceptions and skill deficits. Findings also revealed that parental direct involvement in decision making process was low although their indirect participation via parent-student-teacher association was better. Finally, parents of children with disabilities in the study area did not involve at all in volunteering and community activities to support their children’s education. Thus, the schools are required to organize discussions and trainings that would enable parents of children with disabilities recognize and discharge their multifaceted roles.

description: In the design of a diffraction-limited storage ring (DLSR) consisting of compact multi-bend achromats (MBAs), it is challenging to simultaneously achieve an ultralow emittance and a satisfactory nonlinear performance, due to extremely large nonlinearities and limited tuning ranges of the element parameters. Nevertheless, taking the High Energy Photon Source (HEPS) as an example, we demonstrate that the potential of a DLSR design can be explored with a successive and iterative implementation of the particle swarm optimization (PSO) and multi-objective genetic algorithm (MOGA). It turns out that with a hybrid MBA lattice, it is feasible for the HEPS to attain a natural emittance of about 50 pm.rad, and meanwhile, realize a sufficient ring acceptance for beam accumulation with an on-axis longitudinal injection scheme. Particularly, this study indicates that a rational combination of the PSO and MOGA is more effective than either of them alone in approaching the true global optima, for an explorative multi-objective problem with many optimizing variables and local optima.

description: Today, people have access to abundant information. Hence, differentiation is considered as an important strategy to get seen by the target audience. To this end, organizations need to use unique corporate identities to create positive images. Accordingly, universities are required to plan and communicate their identities to build sustained collaborations with key stakeholders. This study aimed at examining corporate branding and communication strategies in Ethiopian Public Higher Institutions. Using stratified systematic sampling, six first generation universities and six proximate preparatory schools were selected. Then, using quota sampling method, a total of 300 regular students (50 from each university) and 300 preparatory students (50 from each school) were selected. Besides, 12 corporate communication personnel (2 from each university) were involved. A descriptive research method was used employing both qualitative and quantitative approaches. Data have been gathered using questionnaire, interview, content analysis and observation. The results show that universities have not implemented effective corporate branding and communication strategies; there are gaps in branding their institutions using unique features and in communication utilizing effective strategies. Students pointed out that they have not been provided with consolidated information about the universities. Hence, they relied on information from other people such as family members, friends, and teachers etc to choose their preferred university. This implies that universities need to assess their corporate branding and communication strategies. Most importantly, the issue needs further studies for better understanding of the problem in all the universities to implement effective educational branding and communication strategies.

description: In the last thirteen years since the discovery of oil and gas resources in Uganda, numerous developments have taken place to pave way for the development of oil and gas sector which necessitated land acquisition. In response, interventions such as cash compensation, partial land acquisition and resettlement were undertaken. The lacuna for this study is that, there is limited research that focuses on the experiences of women in oil-induced land dispossession, compensation and resettlement in relation to their reliance on the land for livelihood. This paper, therefore, aims at evaluating these experiences on land compensation dispossession for oil and gas development activities and the impact on women’s livelihoods in Albertine region. A phenomenological study research design was adopted through multimethod such as in-depth interviews, focus group discussions, covert observation and documentary evidence. Purposive sampling was used to select women in categories and snowball sampling to trace displaced women who were not resettled. Findings indicate that cash compensation and resettlement process had loopholes that failed to deal with social, cultural and economic aspects of the affected communities. In conclusion, oil induced compensation process has had devastating experiences on women and many have become more vulnerable. We argue that the negative lived experiences by women as a result of compensation process were attributed to their subordinate status in the rural communities in respect to property ownership and household decision making. The study recommends that future land compensation, resettlement and implementation strategies be gender-inclusive in order to mitigate negative impacts on women livelihoods.

description: In this work we include electron-electron interaction beyond Hartree-Fock level in our non-equilibrium Green's function approach by a crude form of GW through the Single Plasmon Pole Approximation. This is achieved by treating all conduction band electrons as a single effective band screening the Coulomb potential. We describe the corresponding self-energies in this scheme for a multi-subband system. In order to apply the formalism to heterostructures we discuss the screening and plasmon dispersion in both 2D and 3D systems. Results are shown for a four well quantum cascade laser with different doping concentration where comparisons to experimental findings can be made.

description: Marriage is one of the essentials of society that forms the basis for family institution. Even though harmony and permanence are emphasized ideals in a marriage, spouses, however, enter into disputes due to various factors. In most part of Oromia region, family arbitrators play important role in settling disputes arising out of marriage though their previous power is detracted by the region’s family law. Hence, this study investigates the actual roles of family arbitrators in settling disputes arising out of marriage, and the practical and legal challenges therein using a socio-legal approach. To this end, a descriptive cross-sectional qualitative research design was employed. The study used multi-stage and random sampling techniques to identify the study areas, and purposive sampling technique to select respondents. Data were collected through in-depth interview, focus group discussion, and key informant interview. Then, they were sorted out, categorized, and analyzed thematically. Despite the withering away of their power by the Oromia family law and other challenges they have, the study has revealed that family arbitrators still play a significant role in settling disputes arising out of marriage, particularly in the countryside. Besides, it is uncovered that the family law lacks a strong socio-cultural base during its enactment which in turn has led to its unsatisfactory implementation. To ensure the compatibility between the law and the culture, and make family arbitration effective, equitable and context sensitive, the study suggests the need for proper harmonization between the law and the culture of the society by concerned stakeholders.

description: “What does it mean to be here?” This was the initial research question of this thesis. Over the course of my MFA, I have lived in two countries: Canada (my birthplace) and Mexico. But the question of belonging is more than merely geographical. What began with a focus on questioning what it meant to belong in either country developed into an understanding of how knowledge creation develops in my practice. Through an iterative collaborative process with henequén fibre, I came closer to understanding childhood influences on my practice and politics in modes of making. With common Mexican materials, I began to learn and respect the unpredictable ecologies of plants and objects. This thesis is my attempt to make sense of our world through the social, corporeal, and sculptural components in my practice. It is a journey that will begin over and over again, and is led by my curiosity in the question: How have we been made?
Certified Descent Algorithm for shape optimization driven by fully-computable a posteriori error estimators

description: In this paper we introduce a novel certified shape optimization strategy - named Certified Descent Algorithm (CDA) - to account for the numerical error introduced by the Finite Element approximation of the shape gradient. We present a goal-oriented procedure to derive a certified upper bound of the error in the shape gradient and we construct a fully-computable, constant-free a posteriori error estimator inspired by the complementary energy principle. The resulting CDA is able to identify a genuine descent direction at each iteration and features a reliable stopping criterion. After validating the error estimator, some numerical simulations of the resulting certified shape optimization strategy are presented for the well-known inverse identification problem of Electrical Impedance Tomography.
Super Bloch Oscillation in a PT symmetric system

description: Wannier-Stark ladder in a PT symmetric system is generally complex that leads to amplified/damped Bloch oscillation. We show that a non-amplified wave packet oscillation with very large amplitude can be realized in a non-Hermitian tight binding lattice if certain conditions are satisfied. We show that pseudo PT symmetry guarantees the reality of the quasi energy spectrum in our system.

description: This thesis examines the organization of different brain networks using mathematical representations of brain function. It identified how hierarchical organization emerges in early life, using brain imaging data from infants and adolescents. Disruptions to this framework can subsequently impact cognitive abilities in adults and clinical outcomes in patients with schizophrenia.
A Historical Analysis of Magaalaa Guddoo (Gidir Magaalaa) Market Centre in Harar City (1938-1991)
Creators: name: Girma, Zerihun
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2019

description: This paper presents the historical developments in and around Magaalaa Guddoo market centre in Harar city. It discusses the role of early market centres in the early civilizations in Ethiopia by focusing on Magaalaa Guddoo. Magaalaa Guddoo was the biggest and the oldest market centre of Harar city which pulled together all the merchants and merchandises coming into Jugol (the wall that surrounds the historic Harar city) through all its gates. That was why different writers regarded it as ‘the central market’ or ‘the main market’. It is estimated that this market centre was founded in 13th or 14th century. The paper discusses the establishment of Magaalaa Guddoo market centre; changes and developments in the market by focusing on the Italian period, the imperial and the military regimes. The commodities exchanged in the market, the major actors who used the market, illegal trade, and finally the decline of the market was discussed in detail. Journals, books, archival materials, material remains, oral informants, and magazines were used intensively for the study. Oral informants were identified using snowball sampling method. The findings show that political changes, shifts in supply and demand, and illegal trades are interrelated and have a significant impact on the development and fall of Magaalaa Guddoo market centre. Besides, strategic location and the availability of items of trade are the main factors in the emergence and expansion of Magaalaa Guddoo market centre.

Content Validity of EFL Teacher-Made Assessment: The Case of Communicative English Skills Course at Ambo University
Creators: name: Hirpassa, Motuma
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2019

description: Prompted by increased concerns about the effects of mismatch between assessments and the teaching materials, this study evaluated the content validity of teacher-made assessments of Communicative English Skills Course at Ambo University. To this end, three years (2016, 2017 and 2018) teacher-made assessments and teaching materials of the course were purposively selected. In addition to the documents, twelve English language teachers and nine English major students were purposively included. In the view of a mixed research design, both quantitative and qualitative data were obtained through document analysis, and teachers and students interview techniques. The document analysis focused on six language domains in the course such as writing, listening, reading, speaking, grammar and vocabulary. The interview focused on the challenges that the teachers confronted and the strategies they used to promote the positive effects of content validity of their assessments in the course. Percentage, Mean Ranking and Pearson Sidney Siegel’s Contingency Coefficient were employed to analyze the quantitative data. The qualitative information was also thematically described. The overall result of the study showed that the content validity of the teacher-made assessments was very low (0.211) which in turn reveals negative effects of the assessments on the teaching-learning process of the course. Complex components and demanding nature of the course, student character, constraints and malfunctioned resources as well as teachers’ behaviour were the major challenges to properly implement assessment in the course. Therefore, the solution to the problem lies in bringing about improvement on these challenges.

description: We investigate the evolution of the net-proton kurtosis and the kurtosis of the chiral order parameter near the critical point in the model of nonequilibrium chiral fluid dynamics. The order parameter is propagated explicitly and coupled to an expanding fluid of quarks and gluons in order to describe the dynamical situation in a heavy-ion collision. We study the critical region near the critical point on the crossover side. There are two sources of fluctuations: non-critical initial event-by-event fluctuations and critical fluctuations. These fluctuations can be distinguished by comparing a mean-field evolution of averaged thermodynamic quantities with the inclusion of fluctuations at the phase transition. We find that while the initial state fluctuations give rise to flat deviations from statistical fluctuations, critical fluctuations reveal a clear structure of the phase transition. The signals of the critical point in the net-proton and sigma field kurtosis are affected by the nonequilibrium dynamics and the inhomogeneity of the space-time evolution but develop clearly.
