Year: 2019

description: The aim of this study is to provide an initial understanding of determinants of product adoption of packed Ethiopian cultural stew food adoption in Addis Ababa. In order to achieve this aim, this study identified and examined various attitudinal, normative and control factors and their possible influence upon packed Ethiopian cultural stew adoption. The data on these variables was collected using a structure questionnaire survey approach. The study population compromised of Bole sub-city of Addis Ababa where data was collected from 231 customers of Tapu prepared food P.L.C by using conventional sampling. The researcher used explanatory research to study the relationship between the dependent variable (product adoption) and the independent variables (attitude towards behavior, subjective norm and perceived behavioral control). Questionnaire were analyzed using SPSS version 20.00 and tools like correlation and multiple regression were employed. Study findings indicated that product adoption and attitude towards behavior were positively and significantly (β= 1.896, p<0.05) it accounted for 97.1% of the variance in product adoption.. The results also indicated that subjective norm and product adoption were positively and significantly related (β=1.223, p<0.05) and it accounted for 85.5% of the variance in product adoption. The results further indicated that perceived behavioral control, had a positive and significant relationship (β=1.588, p<0.05) and that it accounted for 88.6% of the variations in product adoption. The results also indicated that pricing and product adoption were significantly and negatively related (β=-0.381, p<0.05). From the findings the study therefore recommended that Cost of packed stew food may need to be lowered in order to attract new consumers as well as to retain the existed customers.

description: Strong electronic correlations related to a repulsive local interaction suppress the electronic compressibility in a single-band model, and the capacitance of a corresponding metallic film is directly related to its electronic compressibility. Both statements may be altered significantly when two extensions to the system are implemented which we investigate here: (i) we introduce an attractive nearest-neighbor interaction $V$ as antagonist to the repulsive on-site repulsion $U$, and (ii) we consider nano-structured multilayers (heterostructures) assembled from two-dimensional layers of these systems. We determine the respective total compressibility $κ$ and capacitance $C$ of the heterostructures within a strong coupling evaluation, which builds on a Kotliar-Ruckenstein slave-boson technique. Whereas the capacitance $C(n)$ for electronic densities $n$ close to half-filling is suppressed---illustrated by a correlation induced dip in $C(n)$---it may be appreciably enhanced close to a van Hove singularity. Moreover, we show that the capacitance may be a non-monotonic function of $U$ close to half-filling for both attractive and repulsive $V$. The compressibility $κ$ can differ from $C$ substantially, as $κ$ is very sensitive to internal electrostatic energies which in turn depend on the specific set-up of the heterostructure. In particular, we show that a capacitor with a polar dielectric has a smaller electronic compressibility and is more stable against phase separation than a standard non-polar capacitor with the same capacitance.
A theoretical study of the build-up of the Sun's polar magnetic field by using a 3D kinematic dynamo model

description: We develop a three-dimensional kinematic self-sustaining model of the solar dynamo in which the poloidal field generation is from tilted bipolar sunspot pairs placed on the solar surface above regions of strong toroidal field by using the SpotMaker algorithm, and then the transport of this poloidal field to the tachocline is primarily caused by turbulent diffusion. We obtain a dipolar solution within a certain range of parameters. We use this model to study the build-up of the polar magnetic field and show that some insights obtained from surface flux transport (SFT) models have to be revised. We present results obtained by putting a single bipolar sunspot pair in a hemisphere and two symmetrical sunspot pairs in two hemispheres.We find that the polar fields produced by them disappear due to the upward advection of poloidal flux at low latitudes, which emerges as oppositely-signed radial flux and which is then advected poleward by the meridional flow. We also study the effect that a large sunspot pair, violating Hale's polarity law would have on the polar field. We find that there would be some effect---especially if the anti-Hale pair appears at high latitudes in the mid-phase of the cycle---though the effect is not very dramatic.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: The study is generally intended to investigate challenges and opportunities facing women managers in the executive branch regional level bureaus and offices of the Oromia region. Moreover, it is concerned with identifying attitude of subordinates towards women managers' behavior, and identifying initiatives taken by the organizations and regional government to resolve women managers' problems. To attain these objectives data is collected from secondary and primary sources .Primary data is collected from women and men managers as well as their subordinates using survey questionnaire and semi structured interview schedules. Secondary data is colleted from regional gender related policy documents. The data is presented and analyzed descriptively using percentages, mean and independent sample t-test by the help of SPSS version 13. Furthermore, relevant literatures are also reviewed. It is found that women are generally underrepresented in regional bureaus and offices and the majority of them are not adequately qualified. They do not have better opportunities to hold managerial jobs both in large and newly established executive branch bureaus and offices. Furthermore, they are equally under-represented at all levels of management hierarchy in the study universe. Gap in gender policies, human resource management in its practices, organizational culture and personal barriers are the major challenges for women to join and steps forward in managerial jobs. Despite this fact, the attitudes of both sex subordinates towards women managers are found relatively encouraging. Regional executive branch bureaus and offices, and the regional government have taken some encouraging initiatives to increase women's share of managerial positions. But they are not adequate to dismantle the "glass ceiling" and "glass walls" in managerial occupations although current political environment and international institutions' pressure among others are the available opportunities. Generally, women managers have encountered challenges both within the organization and outside of the organization. The challenges are conditioned by institutional and non institutional factors. Thus, in addition to using available opportunities, policy intervention and collective effort of stakeholders are generally recommended to eliminate the challenges facing women managers in the executive branch regional bureaus and offices of the Oromia state

On the impact of kinetic mixing in beta functions at two-loop
Creators: name: Lyonnet, Florian

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Kinetic mixing is a fundamental property of models with a gauge symmetry involving several $\mathrm{U}(1)$ group factors. In this paper, we perform a numerical study of the impact of kinetic mixing on beta functions at two-loop. To do so, we use the recently published PyR@TE 2 software to derive the complete set of RGEs of the SM B-L model at two-loop including kinetic mixing. We show that it is important to properly account for kinetic mixing as the evolution of the parameters with the energy scale can change drastically. In some cases, these modifications can even lead to a different conclusion regarding the stability of the scalar potential.

description: A supramassive, strongly-magnetized millisecond neutron star (NS) has been proposed to be the candidate central engine of at least some short gamma-ray bursts (SGRBs), based on the "internal plateau" commonly observed in the early X-ray afterglow. While a previous analysis shows a qualitative consistency between this suggestion and the Swift SGRB data, the distribution of observed break time $t_b$ is much narrower than the distribution of the collapse time of supramassive NSs for the several NS equations-of-state (EoSs) investigated. In this paper, we study four recently-constructed "unified" NS EoSs, as well as three developed strange quark star (QS) EoSs within the new confinement density-dependent mass model. All the EoSs chosen here satisfy the recent observational constraints of the two massive pulsars whose masses are precisely measured. We construct sequences of rigidly rotating NS/QS configurations with increasing spinning frequency $f$, from non-rotating ($f = 0$) to the Keplerian frequency ($f = f_{\rm K}$), and provide convenient analytical parametrizations of the results. Assuming that the cosmological NS-NS merger systems have the same mass distribution as the Galactic NS-NS systems, we demonstrate that all except the BCPM NS EoS can reproduce the current $22\%$ supramassive NS/QS fraction constraint as derived from the SGRB data. We simultaneously simulate the observed quantities (the break time $t_b$, the break time luminosity $L_b$ and the total energy in the electromagnetic channel $E_{\rm total}$) of SGRBs, and find that while equally well reproducing other observational constraints, QS EoSs predict a much narrower $t_b$ distribution than that of the NS EoSs, better matching the data. We therefore suggest that the post-merger product of NS-NS mergers might be fast-rotating supramassive QSs rather than NSs.

Technology Adoption of Ethiopian Manufacturing firms: the Case of Textile and Leather Sector
Creators: name: Mekasha, Kumlachew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Technology adoption has emerged as an important determinant of competitiveness in recent global trade. Gaining competitiveness in the quota free trade became a driving force for the manufacturing firms to adopt technologies. However, there has not been much research focused on technology adoption of manufacturing industries in Ethiopia. The purpose of this study is to investigate the status and the effects of organizational and environmental factors on the level of technology adoption. A survey methodology was employed to collect data from 115 firms. A purposive sampling technique was used to select firms those engaged in the manufacturing leather and textile products. A combined quantitative and qualitative data analysis approach was used as an analytical lens to interpret responses gathered from manufacturing enterprises. The data was analyzed by both descriptive and inferential statistics. The reasons, product and process quality improvement and productivity enhancement are firm's primary reason to adopt new manufacturing technology. Comparatively soft technologies are better adopted by the firms than hard technologies. The results revealed that the entire variable, except firm age, positively influences the technology adoption level of a firm. The effect of firm size, certification, competition, employee technical skill, financial resource and government support was significant. On the other hand, the results indicated that the top management commitment and firm age did not have significant effects on the technology adoption level. Recommendations are made for future research on technology adoption within the broader spectrum of manufacturing enterprises Keywords: Technology adoption, organizational and environmental factors, manufacturing enterprises

description: In this paper the Emerging Market Clearing Practice in Ethiopia was investigated in Arada- Subcity: Addis Ababa Data were obtained via interview, questionnaire and personal observation. The questioner designed for the customers and seller(s) and/or owner(s) separately. 79 questioners were distributed to and collected from the customers and from 18 questioners distributed to seller (s) and/or owner(s) 16 (88.9) were collected. 8 seller (s) and/or owner(s) were interviewed and 20 customers who came to purchase the product on Saturday from 4:00pm to 5:00 pm and 10:00am to 11:00am were fill the questionnaire and interviewed. The findings of the study indicated that customers perceived the discount rate as erroneous, the actual price and the displayed discount were in consistence, and there was only a slight reeducation in price. Respondents also indicated that the clearance sales increase their sales volume even if the customers are reluctant to purchase on the specified period and this indicates that customer behavior have its own effect on the applied strategy. The main reason of the boutiques for applying clearance sales was to sell the bulky inventory.

description: We present numerical results within the one-dimensional disordered Hubbard model for several characteristic indicators of the many-body localization (MBL). Considering traditionally studied charge disorder (i.e., the same disorder strength for both spin orientations) we find that even at strong disorder all signatures consistently show that while charge degree of freedom is non-ergodic, the spin is delocalized and ergodic. This indicates the absence of the full MBL in the model that has been simulated in recent cold-atom experiments. Full localization can be restored if spin-dependent disorder is used instead.

description: Segmentation of focal (localized) brain pathologies such as brain tumors and brain lesions caused by multiple sclerosis and ischemic strokes are necessary for medical diagnosis, surgical planning and disease development as well as other applications such as tractography. Over the years, attempts have been made to automate this process for both clinical and research reasons. In this regard, machine learning methods have long been a focus of attention. Over the past two years, the medical imaging field has seen a rise in the use of a particular branch of machine learning commonly known as deep learning. In the non-medical computer vision world, deep learning based methods have obtained state-of-the-art results on many datasets. Recent studies in computer aided diagnostics have shown deep learning methods (and especially convolutional neural networks - CNN) to yield promising results. In this chapter, we provide a survey of CNN methods applied to medical imaging with a focus on brain pathology segmentation. In particular, we discuss their characteristic peculiarities and their specific configuration and adjustments that are best suited to segment medical images. We also underline the intrinsic differences deep learning methods have with other machine learning methods.

Creators: name: Yusuf, Abdulhamid
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2013

description: The study aimed at studying the existence and practices of different dimensions of Corporate Social Responsibility (CSR) in Ethiopian Leather Industry by taking Awash and Addis Ababa tanneries as case studies corresponding to the determinants namely labor pressure, consumer demands, community enforcement, sustainability and profitability, social license and nature of the firm. It is relevant to labors, customers, and industries, especially for leather industries to implement CSR concepts and to get benefit from it. In relation to the methodology, simple random sampling technique was used in selecting respondents. The study has been conducted on the basis of the quantitative and qualitative research techniques to assess the nature or practice of CSR and its determinants in the selected two tanneries. 88 and 35 workers in Awash and Addis Ababa tanneries were selected from the total employees of 654 and 275 in each tannery. Data were collected through questionnaire. Moreover, structured and unstructured interview have been also conducted with managers and administrators of the respected companies through open ended questions which are designed to elicit their perception about the nature of CSR in their respected companies. Finally, the data collected through the questionnaires were coded, entered into computer and analyzed and presented in the form of tables using SPSS version 20 Software. Hence, it is through analysis of the direct relationships that insight is developed between the dependent and independent variables. CSR (dependent variable) was found to have a strong positive relationship with labor pressure, consumer demands, community enforcement, sustainability and profitability. This dissertation concludes with a discussion of the implications of these findings as well as recommendations for further research in the area.

description: In this paper, we introduce Nicil: Non-Ideal magnetohydrodynamics Coefficients and Ionisation Library. Nicil is a stand-alone Fortran90 module that calculates the ionisation values and the coefficients of the non-ideal magnetohydrodynamics terms of Ohmic resistivity, the Hall effect, and ambipolar diffusion. The module is fully parameterised such that the user can decide which processes to include and decide upon the values of the free parameters, making this a versatile and customisable code. The module includes both cosmic ray and thermal ionisation; the former includes two ion species and three species of dust grains (positively charged, negatively charged and neutral), and the latter includes five elements which can be doubly ionised. We demonstrate tests of the module, and then describe how to implement it into an existing numerical code.

description: A principle of an acoustic Eaton Lens array and its application as a removable tsunami wall is proposed theoretically. The lenses are made of expandable rubber pillars or balloons and create a stop-band by the rotating the incoming tsunami wave and reduce the pressure by canceling each other. The diameter of each lens is larger than the wavelength of the tsunami near the coast, that is, order of a kilometer. The impedance matching on the border of the lenses results in little reflection. Before a tsunami, the balloons are buried underground in shallow water near the coast in folded or rounded form. Upon sounding of the tsunami alarm, water and air are pumped into the pillars, which expand and erect the wall above the sea level within a few hours. After the tsunami, the water and air are released from the pillars, which are then buried underground for reuse. Electricity is used to power the entire process. A numerical simulation with a linear tsunami model was carried out.

description: The observation of a protophobic 16.7 MeV vector boson has been reported by a $^8$Be nuclear transition experiment. Such a new particle could mediate between the Standard Model and a dark sector, which includes the dark matter. In this paper, we show some simple models of the dark matter which satisfy the thermal relic abundance under the current experimental bounds from the direct and the indirect detections. In a model, it is found that an appropriate self-scattering cross section to solve the small scale structure puzzles can be achieved.

description: Over the past two decades, digital archiving and building interfaces to access digital archives has been a major challenge at the intersection of computer sciences, arts and humanities. In our project, we approach social media data and website data from artists as a way of self-documentation that we want to archive and bring in context. In this text, we outline the making of Art Doc Viz, an interactive visualization that builds on an open source and machine-learning-based data pipeline designed to bring arbitrary amounts of artists' self-documented work from different sources (for example Instagram and websites) into a visualization structure that makes it accessible interactively and in 3D, and that makes relations between the artists' documentations visible. This is achieved by using a series of AI tools like entity recognition and image recognition and UMAP as a clustering algorithm. Finally, the visualization uses advanced 3D graphics to enable the user to explore the visualization in an intuitive way.

description: Classical lattice Yang-Mills calculations provide a good way to understand different nonequilibrium phenomena in nonperturbatively overoccupied systems. Above the Debye scale the classical theory can be matched smoothly to kinetic theory. The aim of this work is to study the limits of this quasiparticle picture by determining the plasmon mass in classical real time Yang-Mills theory on a lattice in 3 spatial dimensions. We compare three methods to determine the plasmon mass: a hard thermal loop expression in terms of the particle distribution, an effective dispersion relation constructed from fields and their time derivatives, and by measuring oscillations between electric and magnetic field modes after artificially introducing a homogeneous color electric field. We find that a version of the dispersion relation that uses electric fields and their time derivatives agrees with the other methods within 50%.

description: In today's business environment, especially in the banking industry there is strong competition and dynamics of markets. Due to this complexity, commercial banks need to identify the criteria on which customers determine their bank selection decision. Therefore the objective of this study is to investigates the determinants of bank selection in Addis Ababa, Ethiopia, and how customers rank the factors based on their importance level to patronize banks and banking service. In the meanwhile, this study also provides results of whether the variables such as Service Quality, Convenience/Security, Technology, Marketing & Promotion, Bank Image, Financial benefits, Bank's Reputation and Proximity have significant effect on bank selection decision. Both qualitative and quantitative data analysis techniques, using responses given by 358 bank customers in Addis Ababa city from different occupation, age and income group is employed in the analysis. Two stages stratified sampling method was used and data analysis was conducted by using descriptive and inferential statistical tools with the help SPSS version 22 for windows. Finding this study showed that Convenience/Security, Technology, Marketing & Promotion, Bank's Image and Proximity have significant positive relationship with bank selection decision while Service quality, Financial benefits and Bank's reputation have significant negative relationship with bank selection and 86.6% of bank selection decision explained by independent variables.

description: The carrier emission efficiency of light emitting diodes is of fundamental importance for many technological applications, including the performance of GaN and other semiconductor photocathodes. We have measured the evolution of the emitted carriers and the associated transient electric field after femtosecond laser excitation of n-type GaN single crystals. These processes were studied using subpicosecond, ultrashort, electron pulses and explained by means of a three-layer analytical model. We find that for pump laser intensities on the order of 10^11 W/cm^2, the electrons that escaped from the crystal surface have a charge of about 2.7 pc and a velocity of about 1.8 um/ps. The associated transient electrical field evolves at intervals ranging from picoseconds to nanoseconds. These results provide a dynamic perspective on the photoemission properties of semiconductor photocathodes.

description: Learning graph embeddings is a crucial task in graph mining tasks. An effective graph embedding model can learn low-dimensional representations from graph-structured data for data publishing benefiting various downstream applications such as node classification, link prediction, etc. However, recent studies have revealed that graph embeddings are susceptible to attribute inference attacks, which allow attackers to infer private node attributes from the learned graph embeddings. To address these concerns, privacy-preserving graph embedding methods have emerged, aiming to simultaneously consider primary learning and privacy protection through adversarial learning. However, most existing methods assume that representation models have access to all sensitive attributes in advance during the training stage, which is not always the case due to diverse privacy preferences. Furthermore, the commonly used adversarial learning technique in privacy-preserving representation learning suffers from unstable training issues. In this paper, we propose a novel approach called Private Variational Graph AutoEncoders (PVGAE) with the aid of independent distribution penalty as a regularization term. Specifically, we split the original variational graph autoencoder (VGAE) to learn sensitive and non-sensitive latent representations using two sets of encoders. Additionally, we introduce a novel regularization to enforce the independence of the encoders. We prove the theoretical effectiveness of regularization from the perspective of mutual information. Experimental results on three real-world datasets demonstrate that PVGAE outperforms other baselines in private embedding learning regarding utility performance and privacy protection.

description: The purpose of this study was to evaluate the Comparative Analysis of Financial Performance of Private Commercial Banks in Ethiopia for the period of 5 years from 2012 to 2016. To this end, review of relevant theoretical and empirical literature was made. Besides, data/information on financial performance that are believed to affect performance of private commercial banking in Ethiopia was gathered from sources such as reports of National Bank of Ethiopia and that of respective private commercial banks, and other relevant sources. Then, the gathered data/information was presented, analyzed and described using quantitative techniques. Financial ratios were employed to measure the profitability, liquidity, asset quality and efficiency as well as growth rate in total assets and total income of banks; in addition Analysis of Variance (ANOVA) was used to test the significance differences of profitability, liquidity and efficiency means among peer banks groups. Ethiopian private commercial banking sector remained stable; banks are adequately capitalized and profitable and remained in a sound position. The study found that, there is no a significant means difference of profitability among of peer banks groups in terms of ROE and NIM. However, a significance differences among banks group is existed in terms of ROA. And also there is no a significant means difference of liquidity among of peer banks groups in terms of loan to total assets, liquid asset to deposit and loan to deposit. There is a significance difference of efficiency among banks group is existed in terms of cost income ratio (CIR). The possible recommendations are strong measurement framework should be deployed ROA improvement targets through the management structure of the organization. Resource mobilization is a must in order to narrow the gap between the loan demand and its provision or supply of the financial resources. Performance improvement is required in order to lower the C/I ratio and becomes the better performer in the banking sector. Improving the ability of management to identify and manage credit risk is also required in order to have a better quality in asset.
