description: Over the last decade block-structured adaptive mesh refinement (SAMR) has found increasing use in large, publicly available codes and frameworks. SAMR frameworks have evolved along different paths. Some have stayed focused on specific domain areas, others have pursued a more general functionality, providing the building blocks for a larger variety of applications. In this survey paper we examine a representative set of SAMR packages and SAMR-based codes that have been in existence for half a decade or more, have a reasonably sized and active user base outside of their home institutions, and are publicly available. The set consists of a mix of SAMR packages and application codes that cover a broad range of scientific domains. We look at their high-level frameworks, and their approach to dealing with the advent of radical changes in hardware architecture. The codes included in this survey are BoxLib, Cactus, Chombo, Enzo, FLASH, and Uintah.
Customers' Perception of Service Quality in Ethiopia banking sector: An Exploratory study
Creators: name: Gebre, Yonatan
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: This exploratory study seeks to assess customers' perception of service quality in the banking sector in Ethiopia. Three banks (Commercial Bank of Ethiopia, Awash International Bank and United Bank) included in the study. The SERVQUAL model was used to determine customers' perception of service quality at each of the three banks. The findings reveal that there the customers' expectations are not meet. Among the five dimensions of service quality Tangible and Responsiveness have higher gap scores at CBE and AIB. The Reliability dimension shows a negative gap score at all three banks showing that the customers do not perceive the banks provides consistent service. Farther, the Empathy dimension has a higher negative gap at AIB and UB suggesting that the banks need to train their staff on proper customers' service techniques. While ranking the five dimensions respondents rated Reliability as the most important service quality indicator at the three banks. The study also indicates that the banks need to become more responsive and assuring to their customers as well as increase their accessibility. Key words: SERVQUAL, Quality in Ethiopia Banks, CBE, AIB, UB, Service Quality

Challenges and Opportunities of Small and Medium Scale Enterprises (SMEs) in Addis Ababa (The Case of Arada Sub City)
Creators: name: Tezera, Habtamu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1997

description: Despite the tremendous increase in number of SMEs, little research exists that examines challenges and opportunities of small and medium enterprises (SMEs) in developing countries, especially in Ethiopia. SMEs occupy a prominent position in the development agenda of many developing countries like Ethiopia. SMEs are long recognized as important vehicles of economic diversification, employment creation, income generation and distribution, and poverty alleviation. The number of SMEs in Ethiopia is steadily growing. But, much more important than their number is their current status, stage and pace of development The government of Ethiopia has been promoting the development of SMEs through the formulation and implementation of Micro and Small Enterprises Development Strategy as of November 1997. The purpose of the study is to identify the challenges and opportunities of the SMEs in Arda sub city and to give recommendations based on the problems. Primary data were collected from 115 SMEs in Arada Sub city of the capital city; Addis Ababa. The study covers almost all sectors that identified by Addis Ababa city administration SMEs office. Therefore the study identifies the major factors towards the success of the SMEs by considering all sectors The findings indicated that SMEs face different problems. These problems are financial factors, marketing, management and HRM factors, environmental factors and the like. Inadequacy and costly of credit facilities and sources is the major problem of the SMEs in the sub city. More over Shortage of working capital, intensity of competition, like lack of business development services, collateral requirement by financial institutions, conflict with neighbors and lack of transparency among SMEs office at the time of allocating the working place were the major problems identified in the study. The study shows that sole proprietorship form of SMEs is most common in Arda sub city. All of the sample firms were owned by citizens only. The findings indicated that SMEs use informal sources finance than formal sources. The sources of capital for SMEs in the sub city falls under the two traditional sources; borrowing from friends & relatives and personal saving. Other informal sources like "Equib" play the great role than the formal sources like microfinance. Most of SMEs prepare business plan but they did not have business associations. The findings of the study have important implications for SMEs, support agencies and future research by academics, consultants and researchers.

description: Using suitable modified energies we study higher order Sobolev norms' growth in time for the nonlinear Schrödinger equation (NLS) on a generic $2d$ or $3d$ compact manifold. In $2d$ we extend earlier results that dealt only with cubic nonlinearities, and get polynomial in time bounds for any higher order nonlinearities. In $3d$, we prove that solutions to the cubic NLS grow at most exponentially, while for sub-cubic NLS we get polynomial bounds on the growth of the $H^2$-norm.

description: We systematically study the tidal deformability for neutron and hyperon stars using relativistic mean field (RMF) equations of state (EOSs). The tidal effect plays an important role during the early part of the evolution of compact binaries. Although, the deformability associated with the EOSs has a small correction, it gives a clean gravitational wave signature in binary inspiral. These are characterized by various love numbers kl (l=2, 3, 4), that depend on the EOS of a star for a given mass and radius. The tidal effect of star could be efficiently measured through advanced LIGO detector from the final stages of inspiraling binary neutron star (BNS) merger.

description: Globalization has opened the borders of countries, due to which the competition between the companies intensified it became necessary to guide and manage not the usual a manager, but a globally minded manager or leader. Even today, the question of the phenomenon of leadership is controversial among scientists about, in particular, how should he be a leader, with qualities or skills, whether it is possible to learn leadership, etc. Cross-Country Perceptions of Leadership Skills and Traits is different. There are different views on it in terms of vertical management hierarchy and network structuring. of business network structures clearly influence organizational culture he showed us about the leader and leadership. In such conditions, when Georgia is also one of the members of the global world, in relation to the compatibility of Georgian culture, the issue of how it should be in Georgia should be studied the leader of a functioning company, what qualities and skills should have, what features of Georgian culture should he grasp and, finally, what should he be able to give for the success of the company "As a victim". The world is changing at lightning speed and also at lightning speed public interest in leadership and leaders is growing. We all have a certain view of what leadership is, however the exact definition of the term is still difficult. Some scientists believe that leadership is the result of successful group dynamics, Others believe that leadership is determined by the grandiose efforts of a person. There is also an opinion that the leader is influenced by circumstances and necessity creates, however, according to another opinion, leadership a person with qualities is always a leader.

description: Innovation makes it possible to produce more products with less materials and resources, which in turn leads to economic growth. The main problem of financing innovative projects is the high risk of returns and long payback. Most of these projects do not have enough guarantee funds, their resources are limited, and only their own ideas and technologies are the backbone. Due to the high risk of innovative projects, it is necessary to use venture capital to finance them.

The Influence of Ownership Structure on Corporate Performance; Evidence from selected Ethiopian companies
Creators: name: Belay, Mikael
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This paper explores the influence of ownership structure and firm performance among selected Ethiopian companies. The data collected for this research is for the period 2008-2010 and the sample consists of 23 companies among which 5 are sole proprietorship, 8 partnership and 10 share companies. Three specific research questions are applied to explore the relationships between the ownership structure (characterized by owners' identity and ownership concentration) and firm performance. Ownership concentration is measured by the percentage of shares owned by the largest five shareholders and HHI while the performance measures applied are ROA and ROE. While analyzing the linear regression, the ownership structure measures were treated as independent variables and the firm performance measures were treated as dependent variables controlling for firm size, firm age and debt ratio. The results indicate that there is no statistically significant performance difference between solely owned, partner controlled and diffused firms. However, the linear regression analysis shows that young solely owned firms have better performance compared to old solely owned firms. The other result shows that, there are positive relationships between institutional and foreign ownership and firm performance measures. Whereas, the correlation of government ownership and firm performance measure reveals a negative sign. Key Words: Ownership Structure; Ownership Concentration; Ownership Identity; Firm Performance

Dramatic change of photoexcited quasiparticle relaxation dynamics across Yb valence state transition in YbInCu$_4$

description: YbInCu$_4$ undergoes a first order structural phase transition near $T_v$=40 K associated with an abrupt change of Yb valence state. We perform ultrafast pump-probe measurement on YbInCu$_4$ and find that the expected heavy fermion properties arising from the \emph{c-f} hybridization exist only in a limited temperature range above $T_v$. Below $T_v$, the compound behaves like a normal metal though a prominent hybridization energy gap is still present in infrared measurement. We elaborate that those seemingly controversial phenomena could be well explained by assuming that the Fermi level suddenly shifts up and becomes far away from the flat \emph{f}-electron band as well as the indirect hybridization energy gap in the mixed valence state below $T_v$.

description: Quantum fluctuations of the electromagnetic vacuum impose an observable quantum limit to the lowest temperatures that can be reached with conventional laser cooling techniques. As laser cooling experiments continue to bring massive mechanical systems to unprecedented temperatures, this quantum limit takes on increasingly greater practical importance in the laboratory. Fortunately, vacuum fluctuations are not immutable, and can be "squeezed" through the generation of entangled photon pairs. Here we propose and experimentally demonstrate that squeezed light can be used to sideband cool the motion of a macroscopic mechanical object below the quantum limit. To do so, we first cool a microwave cavity optomechanical system with a coherent state of light to within 15% of this limit. We then cool by more than 2 dB below the quantum limit using a squeezed microwave field generated by a Josephson Parametric Amplifier (JPA). From heterodyne spectroscopy of the mechanical sidebands, we measure a minimum thermal occupancy of 0.19 phonons. With this novel technique, even low frequency mechanical oscillators can in principle be cooled arbitrarily close to the motional ground state, enabling the exploration of quantum physics in larger, more massive systems.

Artificial Intelligence based Prediction of employment opportunities and its Impact on Oman Economy

Year: 2022

description: Due to the increasing reliance on artificial intelligence in all aspects of life and work, workers, especially those in non-technical positions, are concerned about the increasing effects of using artificial intelligence, which is important to how employees see the future of their work. Many companies rely on AI capabilities and software in their daily routine. Also, many workers have become noticeably concerned about the possibility of losing their jobs due to the use of artificial intelligence. The proposed solution to this problem is to rely on humans and artificial intelligence at the same time because they complement each other and correct this misconception, but we cannot deny that artificial intelligence and technology will continue to advance and penetrate most of the work of human resource management. For example, AI is more useful or suitable for routine tasks that involve complex operations, while we do not disagree that humans are best suited in unpredictable environments, or in environments that require social intelligence. The primary role of AI is to help HR administrators focus on the core functions of HR, making them more efficient and dedicated to their work to become leaders to others. We will use the methodology of training workers and employees and preparing them for the rapid development of technology to become more dedicated to their work and have experience in dealing with artificial intelligence professionally. For example, (smart) computer programs will take on more tedious tasks such as setting employee work schedules, distributing simple tasks, doing initial monitoring of employee performance and other tasks, giving the opportunity for human managers to be a better role model at work.

An Axion-induced SM/MSSM Higgs Landscape and the Weak Gravity Conjecture

description: We construct models in which the SM Higgs mass scans in a landscape. This is achieved by coupling the SM to a monodromy axion field through Minkowski 3-forms. The Higgs mass scans with steps given by delta(m_H^2)= eta mu f, where mu and f are the axion mass and periodicity respectively, and eta measures the coupling of the Higgs to the associated 3-form. The observed Higgs mass scale could then be selected on anthropic grounds. The monodromy axion may have a mass mu in a very wide range depending on the value of eta, and the axion periodity f. For eta=1 and f = 10^10 GeV, one has 10^{-3}eV < mu < 10^3 eV, but ultralight axions with e.g. mu = 10^{-17} eV are also possible. In a different realization we consider landscape models coupled to the MSSM. In the context of SUSY, 4-forms appear as being part of the auxiliary fields of SUSY multiplets. The scanning in the 4-forms thus translate into a landscape of vevs for the N=1 auxiliary fields and hence as a landscape for the soft terms. This could provide a rationale for the MSSM fine-tuning suggested by LHC data. In all these models there are 3-forms coupling to membranes which induce transitions between different vacua through bubble nucleation. The Weak Gravity Conjecture (WGC) set limits on the tension of these membranes and implies new physics thresholds well below the Planck scale. More generaly, we argue that in the case of string SUSY vacua in which the Goldstino multiplet contains a monodromy axion the WGC suggests a lower bound on the SUSY breaking scale m_{3/2} > M_s^2/M_p.

description: Rare event search experiments, such as those searching for dark matter and observations of neutrinoless double beta decay, require ultra low levels of radioactive background for unmistakable identification. In order to reduce the radioactive backgrounds of detectors used in these types of event searches, low background photosensors are required, as the physical size of these detectors become increasing larger, and hence the number of such photosensors used also increases rapidly. Considering that most dark matter and neutrinoless double beta decay experiments are turning towards using noble liquids as the target choice, liquid xenon and liquid argon for instance, photosensors that can work well at cryogenic temperatures are required, 165 K and 87 K for liquid xenon and liquid argon, respectively. The Silicon Geiger Hybrid Tube (SiGHT) is a novel photosensor designed specifically for use in ultra low background experiments operating at cryogenic temperatures. It is based on the proven photocathode plus silicon photomultiplier (SiPM) hybrid technology and consists of very few other, but also ultra radio-pure, materials like fused silica and silicon for the SiPM. The introduction of the SiGHT concept, as well as a feasibility study for its production, is reported in this paper.

description: Motivated by the recent development in strong spin-orbit-coupled materials, we consider the dipole-octupole doublets on the triangular lattice. We propose the most general interaction between these unusual local moments. Due to the spin-orbit entanglement and the special form of its wavefunction, the dipole-octupole doublet has a rather peculiar property under the lattice symmetry operation. As a result, the interaction is highly anisotropic in the pseudospin space, but remarkably, is uniform spatially. We analyze the ground state properties of this generic model and emphasize the hidden multipolar orders that emerge from the dipolar and octupolar interactions. We clarify the quantum mutual modulations between the dipolar and octupolar orders. We predict the experimental consequences of the multipolar orders and propose the rare-earth triangular materials as candidate systems for these unusual properties.

The Impact of Board Demographic Diversity on the Financial Performance of Banks in Ethiopia
Creators: name: Melese, Sitotaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This thesis examined the impact of demographic diversity in terms of gender, ethnicity and age of the BOD on financial performance of banks in Ethiopia. The theoretical foundations of the study suggest that the aspects of demographic diversity have positive, negative or no effect on financial. Financial performance- the dependent variable- was measured using ROA and ROE. The independent variables were gender, ethnic and age diversity. Gender was measured using percentage of women from the total board; ethnic diversity as a dummy variable and age diversity using CV of age. Data on board profile using a checklist and financial statements of banks was collected for five years period 2006-2010 E.C(2013/14-2017/18 G.C). The data was analyzed using fixed effect regression technique with the help of Stata. Hausman was used to choose between fixed and random effect models. The findings reveal that gender, ethnic and age diversity have no effect on financial performance. The empirical data from banks fails to establish any relationship between age, gender and ethnic diversity and ROA and ROE. Thus, the hypotheses that gender, ethnic and age diversity have an impact was not supported by the empirical data. The empirical data only supports the theoretical proposition of no relationship between the dependent and independent variables. All in all, this empirical study contributes to make sense of the inconclusive results of past studies and gives theoretical and practical implications for policy makers and the management of modern companies.

description: Abstract
 The digital transformation has affected literary studies in a variety of ways. First, by making more materials available and second, by opening new avenues of doing research. Many digital approaches to text analysis developed in computer science, computational linguistics, and natural language processing however have primarily been applied to large collections of texts and literary corpora. While these forms of “distant reading” have already produced novel insights and have helped to ask entirely new research questions, methods of distant reading are not the only way of using computers to better understand the works of a single author. My talk will showcase some computational close readings of the American writer Herman Melville and will illustrate that categories of closeness and distance are in fact scalable and not necessarily oppositional. With such a “scalable reading” (Weitin), I will argue that the humanities may find a stance of continuity within the monumental infrastructural change we call digitization.

Assessing Online Banking Service Quality on Customers Satisfaction: The case of United Bank S.C.
Creators: name: Arega, Asrat
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This study tries to assess the quality of service that United Bank S.C is providing to its Online (Internet) Banking customers and thereby to evaluate their satisfaction level with the bank's service delivery and try to see whether the introduction of Online (Internet) Banking services has significantly contributed in increasing the bank's service quality and customers satisfaction. Since the adoption of Online Banking in Ethiopia, some banks' have gone through various technological advancements and the customers' expectation and demand for quality of service is increasing from time to time. So this research paper tries to address this time gap. The first objective of this research is to evaluate the Online Banking service quality offered by United Bank S.C. by using SERVQUAL model. In this research, survey is conducted to measure the gap between customers' expectations and customers' perception regarding Online Banking service on each service quality dimensions. The second objective is to analyze the correlation between service quality dimensions and customer satisfaction. For this purpose, a questionnaire has been designed based on the SERVQUAL approach (perceptions and expectations), which includes five major categories of service quality dimensions and are subdivided into 21 items. Moreover, additional questions are prepared for measuring the overall customer satisfaction. To analyze this data, gap analysis, regression analysis and correlation analysis are used. The results of this research show that in all aspects, United Bank customers' expectation is higher than their perceptions on the Online (Internet) Banking service quality offered by the bank. It means that in all of the five service quality dimensions, there are negative gaps. Thus the bank failed in all of these dimensions to meet its customers' expectations. Also the research finding reveals that service quality dimensions (Reliability, Responsiveness, Security, Empathy, and Tangibility) has a significant impact on customer's satisfaction of United Bank S.C. The major finding of this hypothesis shows that all the service quality determinants are positively correlated to the customer satisfaction. Therefore the bank has to develop a policy package which helps to improve it Online banking service quality thereby ascertain its customers' satisfaction.

It serves as a successor to the Taking Part survey, which ran for 16 years as a continuous face to face survey. Paper surveys are available for those not digitally engaged. Fieldwork started in October 2021 and it is envisaged that the survey will be a key evidence source for Department for Digital, Culture, Media and Sport (DCMS) and its sectors by providing statistically representative national estimates of adult engagement with the DCMS sectors. The survey’s main objectives are to:

Provide a central, reliable evidence source that can be used to analyse cultural, digital, and sporting engagement, providing a clear picture of why people do or do not engage.

Provide data at a county level to meet user needs, including providing evidence for the levelling up agenda.

Underpin further research on driving engagement and the value and benefits of engagement.

Further information on the survey can be found on the gov.uk Participation Survey webpage.

description: It is well known that diverse pieces of models and physical ideas coming from different areas of physics converged in the BCS theory of superconductivity. On the contrary it is little known that the formalism developed in the Tomonaga quantum field theory of the pion-nucleon system was an important ingredient for the development of BCS theory. We discuss the evolution of these ideas in quantum field theory providing an unconventional historical perspective.

Periodic driving control of Raman-induced spin-orbit coupling in Bose-Einstein condensates: the heating mechanisms

description: We focus on a technique recently implemented for controlling the magnitude of synthetic spin-orbit coupling (SOC) in ultra-cold atoms in the Raman-coupling scenario. This technique uses a periodic modulation of the Raman-coupling amplitude to tune the SOC. Specifically, it has been shown that the effect of a high-frequency sinusoidal modulation of the Raman-laser intensity can be incorporated into the undriven Hamiltonian via effective parameters, whose adiabatic variation can then be used to steer the SOC. Here, we characterize the heating mechanisms that can be relevant to this method. We identify the main mechanism responsible for the heating observed in the experiments as basically rooted in driving-induced transfer of population to excited states. Characteristics of that process determined by the harmonic trapping, the decay of the excited states, and the technique used for preparing the system are discussed. Additional heating, rooted in departures from adiabaticity in the variation of the effective parameters, is also described. Our analytical study provides some clues that may be useful in the design of strategies for curbing the effects of heating on the efficiency of the control methods.
Outsourcing in Ethiopia
Creators: name: Mulat, Meresea
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: According to Nicholas Beaumont and Amrik Sohal (2004) outsourcing is a fashionable way of solving some business problems and there are numerous reports of its increasing use. However, the use of outsourcing in Ethiopia is very low with the exception of outsourcing some non-core functions like Security service and Janitorial service. Thus, this variation attracts the researcher to undertake a research with the objective of evaluating the current practice and future potential of outsourcing in the country. This research assessed the current practice of outsourcing, identified those business functions that Ethiopian organizations are willing to outsource and pointed out the reasons for outsourcing and not outsourcing. Accordingly, the use of outsourcing in Ethiopia has been low and highly dominated by noncore business functions such as maintenance and janitorial services, security services and information technology services. The findings also confirm that Ethiopian organizations are willing to outsource non-core business functions, such as maintenance and janitorial services, security services and information technology services. Conversely, the research found out that Accounting and Administration outsourcing service providers will face great challenges form Ethiopian organization to deliver their services. This is mainly due the fact that Ethiopian organizations fear the risk of loss of confidential information and loss of control in outsourcing these business functions. In addition, the organizations assume that the external service providers are not loyal to them in providing such business functions. The most expressed reasons for outsourcing in ascending order are: allowing more focus on core business, improving service level, acquiring innovative ideas and cost savings. On the other hand, the most strongly expressed reasons for not outsourcing, in ascending order, are: loss of control, having no loyalty to company and possible loss of confidentiality.
Stellar populations in the bulges of isolated galaxies

description: We present photometry and long-slit spectroscopy for 12 S0 and spiral galaxies selected from the Catalogue of Isolated Galaxies. The structural parameters of the sample galaxies are derived from the Sloan Digital Sky Survey i-band images by performing a two-dimensional photometric decomposition of the surface brightness distribution. This is assumed to be the sum of the contribution of a Sèrsic bulge, an exponential disc, and a Ferrers bar characterized by elliptical and concentric isophotes with constant ellipticity and position angles. The rotation curves and velocity dispersion profiles of the stellar component are measured from the spectra obtained along the major axis of galaxies. The radial profiles of the Hβ, Mg and Fe line-strength indices are derived too. Correlations between the central values of the Mg 2 and Fe line-strength indices and the velocity dispersion are found. The mean age, total metallicity and total α/Fe enhancement of the stellar population in the centre and at the radius where the bulge gives the same contribution to the total surface brightness as the remaining components are obtained using stellar population models with variable element abundance ratios. We identify intermediate-age bulges with solar metallicity and old bulges with a large spread in metallicity. Most of the sample bulges display super-solar α/Fe enhancement, no gradient in age and negative gradients of metallicity and α/Fe enhancement. These findings support a formation scenario via dissipative collapse where environmental effects are remarkably less important than in the assembly of bulges of galaxies in groups and clusters.

description: This thesis examines the behavioral component and ecological validity of non-image-forming (NIF) effects of daytime electric light exposure and incorporates one systematic review and four independent studies. To explore the behavioral component of the NIF effects, we have developed a new tool Light Exposure Behavior Assessment (LEBA) and used it to categorize, explore and understand how different light exposure behaviors influence our health and wellness. To test the ecological validity of the NIF responses, we designed two experiments where we tested the influence of short-wavelength-enriched light exposure with illuminance within the common indoor lighting standards on alertness and cognitive performance.

description: Using the effective mass theory and the multi-valley envelope function representation, we have developed a theoretical framework for computing the single-electron electronic structure of several phosphorus donors interacting in an arbitrary geometrical configuration in silicon taking into account the valley-orbit coupling. The methodology is applied to three coupled phosphorus donors, arranged in a linear chain and in a triangle, and to six donors arranged in a regular hexagon. The results of the simulations evidence that the valley composition of the single-electron states strongly depends on the geometry of the dopant molecule and its orientation relative to the crystallographic axes of silicon. The electron binding energy of the triatomic linear molecules is larger than that of the diatomic molecule oriented along the same crystallographic axis, but the energy gap between the ground state and the first excited state is not significantly different for internuclear distances from 1.5 to 6.6 nm. Three donor atoms arranged in a triangle geometry have larger binding energies than a triatomic linear chain of dopants with the same internuclear distances. The planar donor molecules are characterized by a strong polarization in favor of the valleys oriented perpendicular to the plane of the molecule. The polarization increases with number of atoms forming the planar molecule.
