Year: 2015

description: Corporate governance has become an issue of global significance and has received new urgency due to various corporate scandals and failure. This study seeks to see impacts of corporate governance mechanism on financial performance of Insurers in Ethiopia. In order to achieve this objective, the study uses mixed research approach. Panel data covering ten year period from 2005 – 2014 are analyzed for nine insurance companies. Also in-depth interview was conducted with selected company board chairmen. The study analyses a range of internal corporate governance variables board size, chief executive compensation, educational qualification of directors ,presence of female directors, frequency of board meeting, other business management experience of directors, industry specific experience of directors and the study also controls the effect of premium growth of Insurers. The Fixed effects technique has been applied to find out the most significant variables from considered internal corporate governance variable. The regression results show that, chief executive compensation, educational qualification of directors, other business management experience of directors, and industry specific experience of directors has positive and significant effects on financial performance of Insurers' proxy by ROA. On the other hand, board size and presence female directors don't have statically significant impacts on Insurers' performance. In addition Contrary to theoretical prediction frequency of board meeting does not have significant effects on Insurers performance. So, stakeholders should give consideration to chief executive compensation, educational qualification of directors, other business management experience of directors, and industry specific experience of directors when they set governance policy for industry as general and for the company specifically.

description: Most of the information we have about the internal rotation of stars comes from modes that are weakly affected by rotation, for example by using rotational splittings. In contrast, we present here a method, based on the asymptotic theory of Prat et al. (2016), which allows us to analyse the signature of rotation where its effect is the most important, that is in low-frequency gravity modes that are strongly affected by rotation. For such modes, we predict two spectral patterns that could be confronted to observed spectra and those computed using fully two-dimensional oscillation codes.

Evaluation of Reporting and Performance of Charities and Societies in Ethiopia
Creators: name: Gelaneh, Amsalu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: For the purpose of this paper, Charities and Societies in Ethiopia mean humanitarian private organization, using its own resources, not profit making and participating to fulfill government efforts with a view to eliminate poverty. There are 1630 registered Charities and Societies in Ethiopia as of May 31, 2010. The major intervention areas of CSs in Ethiopia are; general health, education, agriculture, water and sanitation, child development, HIV/AIDS, and others focused on child and women rights. Evidence compiled by NBE shows that the global resources mobilized by the voluntary sector are immense and this has benefited the country's economy significantly. Between 2004 and first-half of 2008 the total of NGO transfers amounted to US$1.78 billion. The annual break-down of this is greater than earnings from the export of coffee (NBE 2007; 2008). Financial statements prepared by CSs serve as a means to communicate with funding agents, government and other stakeholders. In preparing basic financial statements, CSs in Ethiopia use both generally accepted accounting principles (GAAP) and international financial reporting system (IFRS)/IAS. US GAAP is highly applicable and there is a tendency to use IFRS/IAS in the future. Most CSs in Ethiopia keep records of non- exchange transactions, prepare the three basic financial statements prescribed by FASB, and the statements are continuously validated by independent body. Performance evaluation is undertaken based on major areas; financial management, income independence, board governance, program cost, output and outcome measure, and effective use of volunteer service. For most organizations, a higher percentage of resources spent on program services than on management and fundraising is considered a positive performance indicator. According to the research result most CSs in Ethiopia demonstrate above average performance
Looking at single and binary populations through the lens of massive stellar evolution
Creators: name: Agrawal, Poojan
Publisher: name: Zenodo
Year: 2023

description: Massive binaries play a vital role in governing the evolution of dense stellar systems such as star clusters. The interplay between massive star evolution and cluster dynamics can provide valuable insight into the formation of exotic binaries observed by electromagnetic and gravitational-wave observatories. However, the current tools for computing the evolution of clusters often rely on outdated models for the lives of massive stars. In this talk, I will discuss the uncertain and model-dependent evolution of massive stars and share results from METISSE, a new method for estimating stellar evolution. By using METISSE within binary population synthesis code COSMIC, I will demonstrate how variations in stellar evolution parameters can impact which areas of the binary parameter space result in compact binary mergers. Ultimately, this knowledge will help us better understand the intricate processes involved in the evolution of both star clusters and the formation of unique binary systems.
Assessment of Institutional Performance and Sustainability of Selected Microfinance Institutions: A Data Envelopment Analysis Approach

Year: 2011

description: In this study attempts are made to evaluate the institutional performance and sustainability of six MFIs employing conventional financial performance and sustainability indicators and non-parametric DEA-based malmquist total factor productivity index model. The study period covered 2003 to 2009. DEA-based malmquist total factor productivity index model is applied on panel data to derive total factor productivity growth under both production and intermediation approach which could be decomposed as technological change and technical efficiency change. The results of conventional financial performance and sustainability indicators revealed that all MFIs' outreach performance has increased during the study period. Despite the increase in outreach performance, it is difficult for the institutions to operate and expand without subsidies. This is reflected by their financial self-sufficiency ratios. During the study period all most all MFIs in the sample reported below the minimum requirement financial self-sufficiency ratio. This indicated the long-term sustainability of MFIs is in question once the subsidies are dried-up. Respondents' response also confirmed that grants are preferable as primary source of fund rather than retained earnings and member saving. In the study the researcher identified that, technological change has higher value relevance than technical efficiency gain. By decomposing technical efficiency the researcher also observed pure technical efficiency gain has a substantially higher explanatory power than scale efficiency gain The researcher also found that the intermediation services which is the responsibility of the MFIs to transfer funds from surplus groups such as from savers and donors to the deficit groups particularly borrowers or investors are more productive than the production responsibility of MFIs which considers the institutions as producers of deposits and loans. During the study period the institutions reported average productivity growth of 20.7% under both input and output oriented intermediation approach. In both cases the shift in total factor productivity was observed due to technological progress. Under the production approach in both input and output oriented measures an average productivity deterioration of 5.3% was identified. This decline in productivity was the result of 5.6% retrogresses in technology, though there was a marginal 0.4% gain in technical efficiency

description: We study the effect of a nearby planar wall on the propulsion of a spherical phoretic micro-swimmer driven by reactions on its surface. An asymmetric coverage of catalysts on its surface which absorb reactants and generate products gives rise to an anisotropic interfacial flow that propels the swimmer. We analyse the near-wall dynamics of such a self-phoretic swimmer as a function of the asymmetric catalytic coverage of the surface. By an analysis of the fundamental singularities of the flow and concentration or electrostatic potential gradients generated we are able to obtain and rationalise a phase diagram of behaviours as a function of the characteristics of the swimmer surface. We find a variety of possible behaviours, from "bound states" where the swimmer remains near the wall to "scattering" or repulsive trajectories in which the swimmer ends far from the wall. The formation of some of the bound states is a purely wall-phoretic effect and cannot be obtained by simply mapping a phoretic swimmer to a hydrodynamic one.

description: Delay-coupled electro-optical systems have received much attention for their dynamical properties and their potential use in signal processing. In particular it has recently been demonstrated, using the artificial intelligence algorithm known as reservoir computing, that photonic implementations of such systems solve complex tasks such as speech recognition. Here we show how the backpropagation algorithm can be physically implemented on the same electro-optical delay-coupled architecture used for computation with only minor changes to the original design. We find that, compared when the backpropagation algorithm is not used, the error rate of the resulting computing device, evaluated on three benchmark tasks, decreases considerably. This demonstrates that electro-optical analog computers can embody a large part of their own training process, allowing them to be applied to new, more difficult tasks.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: In theory, foreign bank entry could significantly reduce the cost of credit by bringing capital, technical skills, and product innovation to host countries, which increases competition and leads to improvements in the efficiency of the banking sector, ultimately benefitting customers of the banking system, including small and new enterprises. The main objective of this study is to evaluate the potential impact of foreign bank entry in Ethiopian banking sector and analyses how far the domestic banking sectors are ready to compete with the new technology and modern management system. The quantitative research method was adopted to collect data based on the pre-design survey questionnaires and the result of 134 survey questionnaires were distributed and the analysis done using descriptive statistics like graphical presentation, average, standard deviation, frequency, percentage etc. A cross-sectional design was employed for a data collected and analyzed more than one case at a single time. Only quantitative research approach was also implemented. Out of the total respondents, the indicate samples were selected under the consideration of both purposive and random sampling techniques. The key findings revealed that if foreign banks were entered in the country, the domestic banks would be benefited in all the four dimensions such as potential benefit, potential efficiency, macro-economic and social indicators and potential costs. Therefore, the permeation of foreign bank would improve the domestic banks economic potential, additionally different macroeconomic and social indicators show that the country would be benefited if the foreign bank were permitted. Finally the government should adopt from neighboring country like Kenya and Egypt , those have a long period of experience in supervising foreign bank and revise the investment proclamation that prohibited Foreign bank entry.

description: The influence of out-of-plane oscillations on friction is a well-known phenomenon that has been studied extensively with various experimental methods, e.g. pin-on-disk tribometers. However, existing theoretical models have yet achieved only qualitative correspondence with experiment. Here we argue that this may be due to the system dynamics (mass and tangential stiffness) of the pin or other system components being neglected. This paper builds on the results of a previous study (Popov M. et al. Friction, 2016, submitted) by taking the stiffness and resulting dynamics of the system into account. The main governing parameters determining macroscopic friction, including a dimensionless oscillation amplitude, a dimensionless sliding velocity and the relation between three characteristic frequencies (that of externally excited oscillation and two natural oscillation frequencies associated with the contact stiffness and the system stiffness) are identified. In the limiting cases of a very soft system and a very stiff system, our results reproduce the results of previous studies. In between these two limiting cases there is also a resonant case, which is studied here for the first time. The resonant case is notable in that it lacks a critical sliding velocity, above which oscillations no longer reduce friction. Results obtained for the resonant case are qualitatively supported by experiments.

description: Most proteins are highly flexible and can adopt conformations that deviate from the energetically most favorable ground state. Structural information on these lowly populated, alternative conformations is often lacking, despite the functional importance of these states. Here, we study the pathway by which the Dcp1:Dcp2 mRNA decapping complex exchanges between an autoinhibited closed and an open conformation. We make use of methyl Carr–Purcell–Meiboom–Gill (CPMG) NMR relaxation dispersion (RD) experiments that report on the population of the sparsely populated open conformation as well as on the exchange rate between the two conformations. To obtain volumetric information on the open conformation as well as on the transition state structure we made use of RD measurements at elevated pressures. We found that the open Dcp1:Dcp2 conformation has a lower molecular volume than the closed conformation and that the transition state is close in volume to the closed state. In the presence of ATP the volume change upon opening of the complex increases and the volume of the transition state lies in-between the volumes of the closed and open state. These findings show that ATP has an effect on the volume changes that are associated with the opening-closing pathway of the complex. Our results highlight the strength of pressure dependent NMR methods to obtain insights into structural features of protein conformations that are not directly observable. As our work makes use of methyl groups as NMR probes we conclude that the applied methodology is also applicable to high molecular weight complexes.

description: This paper reflects on the potential of introducing an OER course to empower visually impaired female learners in Karachi, Pakistan, during COVID-19. Through a participatory action research approach, twenty female learners completed an adapted course titled ‘Understanding Open Educational Resources’, offered by the Commonwealth of Learning. For a hands-on experience, they later participated in various collaborative activities. Data was gathered through audio surveys, focus groups, and interviews, and analyzed thematically. Overall, the course empowered participants and shifted their dependencies to independencies. Participants were engaged in communities of practices, and took ownership to search, filter, and create/adapt open learning resources. The course has opened up new avenues for them to benefit their community members in innovative ways. It is proposed to introduce OER in national education policy to ensure educational accessibility among the disadvantaged population.

description: This thesis examines business taxpayers' satisfaction with the tax system. The study focuses on examining the views of taxpayers toward the tax taxpayers' services, tax policy, tax administrative mechanism, and tax law enforcement. The study adopted a sequential explanatory mixed method research approach The data was collected from federal business taxpayers through questionnaire and in-depth interview and descriptive. The collected was analyzed using descriptive data analysis. The findings of this study shows that business taxpayers are not satisfied with the existing tax systems. The ways tax authority provides tax information to taxpayers, tax collection and tax refund, administration capability to solving taxpayers' problem and the area of tax audit procedures are found to be the major dissatisfied areas. Moreover the finding revealed that the tax system is so complex and unfair, discretionary treatment by officers and existent of lack of monitoring in the tax authority. Finally, the thesis suggests a series of measures which could be taken by the government in general and tax authorities in particular are; improving tax policy and administration issues; step up their duty of promoting tax awareness, tax officers should be given intensive and repetitive training to improve their attitude and promoting code of conduct with emphasis on ethical values and finally, tax refund procedure would be improved

description: Current business trends have made it imperative for almost all organization to maintain an internal control system. Internal control system is one of the important functions of every business enterprise to detect accuracy & reliability of financial reporting, misuse of assets, ensuring efficiency of operations and adherence to rules and regulation. Micro finance institutions have a critical role on the growth and development of a country by providing different financial services to the poor and low income people in both rural and urban area. The previous studies on micro finance institution showed that the main problem of micro finance institution were weakness of their internal control system. This study focused on assessment of the internal control system in the micro finance institution to identify the possible areas of deficiencies in the system. The population for the study was made of the nineteen (19) micro finance institutions in Addis Ababa of which three (3) of them was selected as a sample using a purposive sampling techniques based on the year of establishment and the number of branch they have in Addis Ababa. The study used survey method of data collection through questionnaires to employees of the institution and semi-structured interview with the institution management. The data gathered from the respondent was analyzed and interpreted by the help of SPSS software program with the help of bar frequency table, minimum & maximum value, mean and standard deviation. The result indicated that internal control in the institution is satisfactory. Though risk assessment elements with the average mean value of 3.81 is better in the institution, there is adequate control environment, control activity, information & communication and monitoring activity components in the institution. Hence, it needs commitment from both the institution management and responsible authority to improve those specific areas of deficiencies in the internal control elements indicated in the final chapter of the study Key word: internal control system, micro finance.

description: The main purpose of the study was to examine the determinants of dividend payout in Ethiopian private banks. Five years data from 2009/10 to 2013/14 were collected from National bank of Ethiopia and banks audited financial statement. The collected data were analyzed using panel data regression technique. The study used dividend payout as a dependent variable and seven independent variables; they are profitability, liquidity, leverage, lagged dividend payout, growth, size and risk. The finding indicated that among the seven independent variables; lagged dividend payout, growth, size and risk have statistically significant impact on dividend payout; the rest three variables have no statistical significant impact on dividend payout. Therefore, lagged dividend payout, growth, size and risk have a significant impact on dividend payout in Ethiopian private banks and board of directors of banks need to consider these variables while designing their dividend payout policy; on the same token investors need to consider these variables in their investment decisions when they want to make an investment in Ethiopian private banks. Key words: Dividend payout, private banks

description: The polarization of $Λ$ hyperons from relativistic flow vorticity is studied in peripheral heavy ion reactions at FAIR and NICA energies, just above the threshold of the transition to the Quark-Gluon Plasma. Previous calculations at higher energies with larger initial angular momentum, predicted significant $Λ$ polarization based on the classical vorticity term in the polarization, while relativistic modifications decreased the polarization and changed its structure in the momentum space. At the lower energies studied here, we see the same effect namely that the relativistic modifications decrease the polarization arising from the initial shear flow vorticity.

description: Cognitive radio technology allows the secondary users to utilize the spectrum, when it is not occupied by the primary users. Whenever a primary user wants to utilize a channel which is occupied by a secondary user, the secondary user should perform a proactive spectrum handoff to another channel and vacate the selected channel before the primary user utilizes it. This scheme avoids collision between the primary users and secondary users; moreover, increases the throughput of the primary and secondary users. In this paper, a novel proactive spectrum hand protocol based on the Greedy Channel Selection (GCS) is proposed which avoids collision between secondary users, as well as, collision between primary and secondary users. In the proposed scheme, proactive spectrum handoff is based on the SRV (Single Rendezvous) coordination scheme; therefore, the secondary users perform proactive spectrum handoff without using the common control channel. Moreover, the channel selection is distributed which leads to the higher throughput, and lower average service time. The proposed proactive spectrum handoff protocol is compared with the other proactive spectrum handoff protocols. Simulation results illustrate that the proposed protocol outperforms the other protocols regarding higher average throughput and lower average service time.

description: We study the dynamics of superposed nonlinear waves in coherently coupled Gross-Pitaevskii (CCGP) equations with constant (autonomous system) and time varying (non-autonomous system) nonlinearity co-efficients. By employing a linear transformation, the autonomous CCGP system is converted into two separate scalar nonlinear Schrödinger equations and we show that linear superposition of different nonlinear wave solutions of these scalar equations results into several kinds of nonlinear coherent structures namely, coexisting rogue wave-Ma breather, Akhmediev-Ma breathers, collision and bound states of Ma breathers and solitons. Next, the non-autonomous CCGP system is converted into an autonomous CCGP system with a similarity transformation. We show an interesting possibility of soliton compression and appearance of creeping solitons for kink-like and periodically modulated nonlinearity coefficient.

description: Arp194 is a system of recently collided galaxies, where the southern galaxy (S) passed through the gaseous disc of the northern galaxy (N) which in turn consists of two close components. This system is of special interest due to the presence of regions of active star-formation in the bridge between galaxies, the brightest of which (the region A) has a size of at least 4 kpc. We obtained three spectral slices of the system for different slit positions at the 6-m telescope of SAO RAS. We estimated the radial distribution of line-of-sight velocity and velocity dispersion as well as the intensities of emission lines and oxygen abundance $12+\log(\mathrm{O/H})$. The gas in the bridge is only partially mixed chemically and spatially: we observe the O/H gradient with the galactocentric distances both from S and N galaxies and a high dispersion of O/H in the outskirts of N-galaxy. Velocity dispersion of the emission-line gas is the lowest in the star-forming sites of the bridge and exceeds 50-70 km/s in the disturbed region of N-galaxy. Based on the SDSS photometrical data and our kinematical profiles we measured the masses of stellar population and the dynamical masses of individual objects. We confirm that the region A is the gravitationally bound tidal dwarf with the age of $10^7 - 10^8 $ yr, which is falling onto the parent S- galaxy. There is no evidence of the significant amount of dark matter in this dwarf galaxy.

description: It was recently observed that the singular values of the off-diagonal blocks of the matrix sequences generated by the Cyclic Reduction algorithm decay exponentially. This property was used to solve, with a higher efficiency, certain quadratic matrix equations encountered in the analysis of queueing models. In this paper, we provide a sharp theoretical bound to the basis of this exponential decay together with a tool for its estimation based on a rational interpolation problem. Applications to solving $n\times n$ block tridiagonal block Toeplitz systems with $n\times n$ semiseparable blocks and certain generalized Sylvester equations in $O(n^2\log n)$ arithmetic operations are shown.

description: In the growth and development literature, capital accumulation and industrialization are considered the crucial and critical key to economic growth. Given this, many developing countries particularly Ethiopia which follows agriculture led industrialization policy made number of attempts to increase ratio of investment in the country. Tax incentives schemes are among the attempts made to create investment friendly environment. This study poses a general question of whether or not domestic manufacturing investment have increased in Ethiopia because of the tax incentives offered; and thus whether or not offering such incentives has been beneficial to the country. To answer this question the study adopts mixed methods of research by using both descriptive and inferential statistics where primary data is collected using interview with MOFED and ERCA officials and secondary data is collected from different sources such as MOFED,EIA,ERCA,IMF and World bank. Descriptive statistics is used to analyze the trends of domestic manufacturing investment, tax revenue and expense rate of Ethiopia. Inferential statistics is also used by employing time series OLS model. A 23 years secondary data from 1992-2014 was collected then time series OLS regression was applied by employing Log DMIN as dependent variable along with tax incentives as independent variable and GDP growth rate, inflation, market openness and Log transport availability as control variables. The regression analysis is conducted using Eviews 8 software and to account for inherent problems of time series data, different tests such as correlation, autocorrelation and stationarity test were applied. The regression result show that tax incentives and market openness have significant positive long run effect on private domestic manufacturing investment, inflation on the other hand has significant negative long run effect. Hence to promote the performance of domestic manufacturing investment in the country, the study recommended that the government should continue marketing the tax incentive scheme and bring them to be on budget. Further the study recommended that the government should continue working on improving the trade and infrastructural environment of the country

description: The theory of scalar gravity proposed by Nordström, and refined by Einstein and Fokker, provides a striking analogy to general relativity. In its modern form, scalar gravity appears as the low-energy effective field theory of the spontaneous breaking of conformal symmetry within a CFT, and is AdS/CFT dual to the original Randall-Sundrum I model, but without a UV brane. Scalar gravity faithfully exhibits several qualitative features of the cosmological constant problem of standard gravity coupled to quantum matter, and the Weinberg no-go theorem can be extended to this case as well. Remarkably, a solution to the scalar gravity cosmological constant problem has been proposed, where the key is a very small violation of the scalar equivalence principle, which can be elegantly formulated as a particular type of deformation of the CFT. In the dual AdS picture this involves implementing Goldberger-Wise radion stabilization where the Goldberger-Wise field is a pseudo-Nambu Goldstone boson. In quantum gravity however, global symmetries protecting pNGBs are not expected to be fundamental. We provide a natural six-dimensional gauge theory origin for this global symmetry and show that the violation of the equivalence principle and the size of the vacuum energy seen by scalar gravity can naturally be exponentially small. Our solution may be of interest for study of non-supersymmetric CFTs in the spontaneously broken phase.

description: It was shown recently that Birkhoff's theorem for doubly stochastic matrices can be extended to unitary matrices with equal line sums whenever the dimension of the matrices is prime. We prove a generalization of the Birkhoff theorem for unitary matrices with equal line sums for arbitrary dimension.

description: The present study investigated the hypothesis that hydrogen sulfide (H2S) is pro-nociceptive in the formalin model of persistent inflammatory pain in the adult rat. Hind paw injection of formalin evoked a concentration-dependent increase in the hind paw concentration of H2S. Increased concentration of H2S was found in homogenates prepared from hind paws injected with 5% (but not 1.25%) formalin. Correspondingly, animal nociceptive flinching and hind paw edema were maximal with 5% formalin. Both nociceptive flinching and hind paw edema induced by injection of 5% formalin were attenuated by pretreatment with dl-propargylglycine (PPG; 50 mg/kg, i.p.) which is an inhibitor of the H2S synthesizing enzyme cystathionine-γ-lyase (CSE). The effect of pretreatment with PPG was selective and the drug did not influence animal behavior or hind-paw edema with injection of 1.25% formalin. Furthermore, PPG pretreatment attenuated the induction of c-Fos in spinal laminae I–II following injection of 5% formalin. In contrast, co-injection of 1.25% formalin with sodium hydrogen sulfide (NaHS; 1 nmol/0.1 ml), a H2S donor, into the hind paw increased animal nociceptive behavior. Collectively, these findings show that the effect of peripheral H2S in the pathogenesis of inflammatory pain depends, at least in part, on the nociceptive intensity level.

description: The recent trend for acquiring big data assumes that possessing quantitatively more and qualitatively finer data necessarily provides an advantage that may be critical in competitive situations. Using a model complex adaptive system where agents compete for a limited resource using information coarse-grained to different levels, we show that agents having access to more and better data can perform worse than others in certain situations. The relation between information asymmetry and individual payoffs is seen to be complex, depending on the composition of the population of competing agents.
