Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This study examines the determinants of financial performance of commercial banks in Ethiopia by using panel data of seven sample commercial banks out of eighteen commercial banks operated in Ethiopia over the period 2000-2014. Since the data is secondary in nature, the quantitative approach to research was used. Besides, the random effect model was used. Under this study, both internal and external factors were included. The internal factors used in this study include capital adequacy, Asset quality, Earning ability, liquidity management and Bank size whereas, the external factor is foreign exchange rate. Moreover, ROA, ROE and NIM were used to measure the financial performance. This study runs a redundant fixed effects test using Hausman specification test. Hence based on the result random effect model was adopted. Based on the regression result; asset quality, earning ability and bank size have a significant influence on the financial performance of Ethiopian commercial banks measured by return on asset , return on equity and net interest margin. Thus, management bodies of commercial bank should strive to strengthen the identified significant factors. Key words: financial performance, commercial banks

Credit Risk Management and its Impact on Performance on Ethiopian Commercial Banks
Creators: name: Mekasha, Girma
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Credit risk management has become an important topic for financial institutes, especially since the business sector of financial services is related to conditions of uncertainty. The turmoil of the financial industry emphasizes the importance of effective risk management procedures. Consequently, this thesis studies "Credit Risk management and its impact on performance in Ethiopian Commercial Banks." This research objective was formulated in order to gain a better understanding of credit risk management and its impact on performance (return on asset). Credit risk has always been a vicinity of concern not only to bankers but to all in the business world because the risks of a trading partner not fulfilling his obligations in full on due date can seriously jeopardize the affaires of the other partner. The axle of this study is to have a clearer picture of how banks manage their credit risk. In this light, the study in its first section gives a background to the study and the second part is a detailed literature review on banking and credit risk management tools and assessment models. Quantitative research design is employed under the quantitative research design survey method is used. The data were collected by cross sectional survey method. The forth part of this study is analysis of primary data by descriptive statistical tools and on hypothesis testing using regression model. This leads the researcher to conclude in the last section that banks with good credit risk management policies have a lower loan default rate and relatively higher return on asset

description: The influence of periodic shear deformation on nonaffine atomic displacements in an amorphous solid is examined via molecular dynamics simulations. We study the three-dimensional Kob-Andersen binary mixture model at a finite temperature. It is found that when the material is periodically strained, most of the atoms undergo repetitive nonaffine displacements with amplitudes that are broadly distributed. We show that particles with large amplitudes of nonaffine displacements are organized into compact clusters. With increasing strain amplitude, spatial correlations of nonaffine displacements become increasingly long-ranged, although they remain present even in a quiescent system due to thermal fluctuations.

description: Differentially private stochastic gradient descent (DP-SGD) adds noise to gradients in back-propagation, safeguarding training data from privacy leakage, particularly membership inference. It fails to cover (inference-time) threats like embedding inversion and sensitive attribute inference. It is also costly in storage and computation when used to fine-tune large pre-trained language models (LMs). We propose DP-Forward, which directly perturbs embedding matrices in the forward pass of LMs. It satisfies stringent local DP requirements for training and inference data. To instantiate it using the smallest matrix-valued noise, we devise an analytic matrix Gaussian~mechanism (aMGM) by drawing possibly non-i.i.d. noise from a matrix Gaussian distribution. We then investigate perturbing outputs from different hidden (sub-)layers of LMs with aMGM noises. Its utility on three typical tasks almost hits the non-private baseline and outperforms DP-SGD by up to 7.7pp at a moderate privacy level. It saves 3$\times$ time and memory costs compared to DP-SGD with the latest high-speed library. It also reduces the average success rates of embedding inversion and sensitive attribute inference by up to 88pp and 41pp, respectively, whereas DP-SGD fails.

description: Weak-value-amplification permits small effects to be measured as observable changes at the sacrifice of power due to post-selection. The power recycling scheme has been proven to eliminate this inefficiency of the rare post-selection, thus surpassing the limit of the shot noise and improving the precision of the measurement. However, the improvement is strictly limited by the system setup, especially the system loss. Here we introduce a dual recycling model based on the interferometric weak-value-based deflection measurement. Two mirrors, the power-recycling mirror and signal-recycling mirror, are placed at the bright and dark port of the interferometer respectively, creating a composite resonator. The results show that both the power and the signal-to-noise ratio (SNR) are greatly enhanced in a wider range of experimental parameters compared to the power-recycling scheme. This work considerably loosens the constraint of the system setup and further explores the real advantage of weak measurement over traditional schemes.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We present the first molecular dynamics study to probe the mechanisms of anomalous diffusion in cationic surfactant micelles in the presence of explicit salt and solvent-mediated interactions. Simulations show that when the counter ion density increases, saddle-shaped interfaces manifest leading to the formation of branched structures. In experiments, branched structures exhibit lower viscosity as compared to linear and wormlike micelles, presumably due to stress relaxation arising from the sliding motion of branches along the main chain. Our simulations provide conclusive evidence and a mechanism of branch motion and stress relaxation in micellar fluids. Further, depending upon the surfactant and salt concentrations, which in turn determine the microstructure, we observe normal, subdiffusive and superdiffusive motion of surfactants. Specifically, superdiffusive behavior is associated with branch sliding, breakage and recombination of micelle fragments as well as constraint release in entangled systems.

description: Gestational diabetes (GDM) poses a growing health risk to both pregnant women and their offspring. While telehealth interventions for GDM management have proven effective, they have traditionally relied on healthcare professionals for guidance and feedback. Our aim was to explore self-tracking in GDM with wearable sensors from self-discovery (i.e., learning associations between glucose levels and lifestyle) and user experience perspectives. We conducted a mixed-methods study with women diagnosed with GDM, utilizing continuous glucose monitor and three types of physical activity sensors (activity bracelet, hip-worn sensor, and electrocardiography sensor) for a week. Data from the sensors was collected, and participants were later interviewed about their experience with the wearable sensors. Additionally, we gathered maternal nutrition data through a 3-day food diary and recorded self-reported physical activity using a logbook. We discovered that continuous glucose monitors were especially valuable for self-discovery, particularly when establishing links between glucose levels and nutritional intake. Challenges associated with using wearable sensors data for self-discovery in GDM included: (1) Separation of glucose and physical activity data in different applications, (2) Missing key trackable features, such as light physical activity and non-walking activities, (3) Discrepancies in data, and (4) Differences in perceived versus measured physical activity. The placement of sensors on the body emerged as a critical factor influencing data quality and personal preferences. To conclude, an app where glucose, nutrition, and physical activity data are combined is needed to support self-discovery. This app should enable tracking of essential features for women with GDM, including light physical activity, with data originating from a single sensor to ensure consistency and eliminate redundancy.

description: The purpose of the study is investigating the determinants of capital structure for Small Scale Manufacturing Co-operatives (SSMCs) in Ethiopia. Hypotheses utilizing trade-off, pecking order and agency theories are empirically examined using a series of firm characteristics: size, tangibility, profitability, earning volatility, growth and age. A structured record review was made to collect a panel data, which include 13 SSMCs year observations of five years over the period 1998 – 2002 E.C. The findings suggest that size, age, tangibility, and growth variables are the most important determinants of capital structure of SSMCs in Ethiopia. The findings also reveal that the dominant capital structure theories (trade-off, pecking order, and agency theories) appear indeed to be valid for Ethiopian SSMCs' capital structure; in fact, trade-off theory best explains Ethiopian SSMCs' capital structure. All firm specific variables except earnings volatility variable seem to have an effect on the level of leverage in Ethiopian SSMCs. Key words: Capital structure; Small Scale Manufacturing Co-operatives

description: Context. The formation of planetary systems is a common, yet complex mechanism. Numerous stars have been identified to possess a debris disk, a proto-planetary disk or a planetary system. The understanding of such formation process requires the study of debris disks. These targets are substantial and particularly suitable for optical and infrared observations. Sparse Aperture masking (SAM) is a high angular resolution technique strongly contributing to probe the region from 30 to 200 mas around the stars. This area is usually unreachable with classical imaging, and the technique also remains highly competitive compared to vortex coronagraphy. Aims. We aim to study debris disks with aperture masking to probe the close environment of the stars. Our goal is either to find low mass companions, or to set detection limits. Methods. We observed eight stars presenting debris disks ( $β$ Pictoris, AU Microscopii, 49 Ceti, $η$ Telescopii, Fomalhaut, g Lupi, HD181327 and HR8799) with SAM technique on the NaCo instrument at the VLT. Results. No close companions were detected using closure phase information under 0.5 of separation from the parent stars. We obtained magnitude detection limits that we converted to Jupiter masses detection limits using theoretical isochrones from evolutionary models. Conclusions. We derived upper mass limits on the presence of companions in the area of few times the diffraction limit of the telescope around each target star.

description: Tolerance implies enduring trying circumstances with a fair and objective attitude. To determine whether evolutionary advantages might be stemming from diverse levels of tolerance in a population, we study a spatial public goods game, where in addition to cooperators, defectors, and loners, tolerant players are also present. Depending on the number of defectors within a group, a tolerant player can either cooperate in or abstain from a particular instance of the game. We show that the diversity of tolerance can give rise to synergistic effects, wherein players with a different threshold in terms of the tolerated number of defectors in a group compete most effectively against defection and default abstinence. Such synergistic associations can stabilise states of full cooperation where otherwise defection would dominate. We observe complex pattern formation that gives rise to an intricate phase diagram, where invisible yet stable strategy alliances require outmost care lest they are overlooked. Our results highlight the delicate importance of diversity and tolerance for the provisioning of public goods, and they reveal fascinating subtleties of the spatiotemporal dynamics that is due to the competition of subsystem solutions in structured populations.

Financial Risks and Profitability of Commercial Banks in Ethiopia
Creators: name: Lake, Eneyew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2013

description: Commercial banks assume various kinds of financial risks which are related to the financial operation of a business and arise due to the uncertainty in movement of foreign exchange rates, interest rates, credit quality, and liquidity position. Risk may have positive or negative outcomes or may simply result in uncertainty. Therefore in order to increase the return, banks should know which risk factors have greater effect on profitability. Thus, this study examines the impact of financial risks on the profitability of commercial banks for a total of eight commercial banks in Ethiopia, covering the period of 2000-2011. To this end, the study adopts a mixed methods research approach by combining documentary analysis and in-depth interviews. The study reviews the financial records of eight commercial banks in Ethiopia and relevant data on macroeconomic factors considered. The findings of the study show that Credit risk and liquidity risk have a negative and statistically significant relationship with banks' profitability. However, the relationship for interest rate risk and foreign exchange rate risk is found to be statistically insignificant. The study suggests that focusing in credit risk management and keeping optimal level of liquidity which enables banks to meet their contractual commitments could maximize return on assets of Ethiopian commercial banks

description: In this paper, we continue the research on the power of contextual grammars with selection languages from subfamilies of the family of regular languages. In the past, two independent hierarchies have been obtained for external and internal contextual grammars, one based on selection languages defined by structural properties (finite, monoidal, nilpotent, combinational, definite, ordered, non-counting, power-separating, suffix-closed, commutative, circular, or union-free languages), the other one based on selection languages defined by resources (number of non-terminal symbols, production rules, or states needed for generating or accepting them). In a previous paper, the language families of these hierarchies for external contextual grammars were compared and the hierarchies merged. In the present paper, we compare the language families of these hierarchies for internal contextual grammars and merge these hierarchies.

description: We theoretically analyze the contrast observed at the outcrop of a threading dislocation at the GaN(0001) surface in cathodoluminescence and electron-beam induced current maps. We consider exciton diffusion and recombination including finite recombination velocities both at the planar surface and at the dislocation. Formulating the reciprocity theorem for this general case enables us to provide a rigorous analytical solution of this diffusion-recombination problem. The results of the calculations are applied to an experimental example to determine both the exciton diffusion length and the recombination strength of threading dislocations in a free-standing GaN layer with a dislocation density of $6\times10^{5}$~cm$^{-2}$.

description: Precise crop yield prediction provides valuable information for agricultural planning and decision-making processes. However, timely predicting crop yields remains challenging as crop growth is sensitive to growing season weather variation and climate change. In this work, we develop a deep learning-based solution, namely Multi-Modal Spatial-Temporal Vision Transformer (MMST-ViT), for predicting crop yields at the county level across the United States, by considering the effects of short-term meteorological variations during the growing season and the long-term climate change on crops. Specifically, our MMST-ViT consists of a Multi-Modal Transformer, a Spatial Transformer, and a Temporal Transformer. The Multi-Modal Transformer leverages both visual remote sensing data and short-term meteorological data for modeling the effect of growing season weather variations on crop growth. The Spatial Transformer learns the high-resolution spatial dependency among counties for accurate agricultural tracking. The Temporal Transformer captures the long-range temporal dependency for learning the impact of long-term climate change on crops. Meanwhile, we also devise a novel multi-modal contrastive learning technique to pre-train our model without extensive human supervision. Hence, our MMST-ViT captures the impacts of both short-term weather variations and long-term climate change on crops by leveraging both satellite images and meteorological data. We have conducted extensive experiments on over 200 counties in the United States, with the experimental results exhibiting that our MMST-ViT outperforms its counterparts under three performance metrics of interest.

description: Active financial analysis has become one of the important tools that actuaries use to model the underwriting and investment operations of insurance companies. The first step in carrying out the analysis is to investigate the most important factors affecting company profitability. This study seeks to find the determinants of insurance companies' profitability in Ethiopia. In order to achieve this objective, the study used mixed research approach. Panel data covering eleven-year period from 2004 – 2014 are analyzed for nine insurance companies. Also in-depth interview is conducted with company managers. The findings of the study showed that underwriting risk, technical provision and solvency ratio have statistically significant and negative relationship with insurers' profitability. However, reinsurance dependence has negative but insignificant relationship with profitability. On the other hand, variables like liquidity, company size and premium growth have a positive and statistically significant relationship with insurers' profitability. In addition, economic growth rate has significant influence on profitability whereas inflation has insignificant influence on insurers' profitability. The study provides evidence that underwriting risk, technical provision and liquidity are the most important factors that affect profitability of insurance companies in Ethiopia. So, the study recommends that Ethiopian insurance companies' managers should give consideration to underwriting risk, technical provision and liquidity to increases their profitability significantly. Keywords: profitability, determinants, insurance

Practice of Commercial Banks in Ethiopia assessment of Liquidity Risk Management
Creators: name: Melak, Tirualem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: The main purpose of the study was to assess the liquidity risk management practice of commercial banks in Ethiopia. To deal with the problem, three fundamental research questions were formulated that stress on the impact of liquidity on performance of banks, the existence of standardized liquidity risk management strategy(practice) and the impact of the directives of NBE on the performance of commercial banks in Ethiopia. To conduct the study, descriptive method was employed. Purposive sampling was used in the selection of each bank and the respondents from the respective bank. Thus a total of 30 respondents participated to the sources of primary data for the study. Data were collected through questionnaire, interview and annual reports of each commercial bank. The data collected from primary and secondary sources were organized using tables and graphs ad interpretation was made on the data using quantitative and qualitative methods. The findings of the study revealed that there is no uniform (standardized) liquidity risk management policy and procedure in the banking industry which is for all commercial banks in Ethiopia. The directives issued by NBE have no significant impact that will affect the performance of commercial banks instead they are important for the normal operations of banks and the industry in general. The over all liquidity position of commercial banks is excess which is caused by low economic development and existence of limited financial instruments in the country. Liquidity position of a bank has an impact on the performance of the bank. Too much liquidity position of a bank decreases the performance of the respective bank unless the excess liquidity position is managed properly. Among the factors that influence liquidity risk management by commercial banks in Ethiopia include: absence of secondary markets, lack of enough financial instruments and absence of strong management information system. Finally, recommendations were forwarded based on the major findings so as to improve the liquidity risk management practice of commercial banks in Ethiopia

description: This study intends to investigate the determinants of profitability in the insurance sector in Ethiopia with reference to general (non-life) insurance companies on basis of data covers six years (2011-2016) period. The study selected sample of twelve (12) insurance companies to study them for a period of six years (2011-2016) with total of 72 observations through panel data. Accordingly, the study used documentary analysis of companies' audited financial statements of general insurers which obtained from NBE and head office of each insurance companies. The key explanatory variables were selected to disclose their relationship and influence on profitability measured by return on asset (ROA) from the prominent previous studies. The CLRM assumptions needed to be fulfilled for OLS that were tested and the residual was found to be homoscedastic, free of Multicollinearity, free of autocorrelation and normally distributed. The results of panel least square regression analysis indicate that industry concentration ratio and leverage, have statistically significant and positive relationship with Non-life insurance business profitability. On the other hand, diversification, underwriting risk and reinsurance dependence has a negative and statistically significant relationship with general insurance companies' profitability. Based on this finding, the study suggests that, the management bodies of the insurance companies should give high attention on firm and industry related variables, particularly by adopting better risk management strategies and better internal control to achieve superior profitability.

description: We construct the solution of type IIB supergravity describing the integrable lambda-deformation of the AdS_3 x S^3 supercoset. While the geometry corresponding to the deformation of the bosonic coset has been found in the past, our background is more natural for studying superstrings, and several interesting features distinguish our solution from its bosonic counterpart. We also report progress towards constructing the lambda-deformation of the AdS_5 x S^5 supercoset.

SKOS

description: Controlled vocabularies are comprehensive collections of domain-specific terms used to describe knowledge within a specific field. They help overcome data ambiguity and offer benefits such as referencing term definitions, promoting semantic interoperability, and facilitating the integration of ontologies. EVOKS is a general-purpose vocabulary service that enables data stewards and scientists to easily create, edit, curate, and publish controlled vocabularies using the W3C recommended SKOS data model. The service ensures access to published vocabularies through the implementation of SKOSMOS, a dedicated vocabulary browser instance. NFDI-MatWerk provides a publicly accessible SKOSMOS instance for publishing vocabularies and an EVOKS instance for editing vocabularies exclusively for its members. The poster showcases the MatWerk Acronyms Vocabulary as an example and highlights the key features and benefits of using EVOKS, including collaborative work, the application of persistent URLs to vocabulary terms, and the integration of controlled vocabularies into metadata schemas.
Working Capital Management and firms' profitability: Evidence from Manufacturing S.C. in Addis Ababa, Ethiopia
Creators: name: Yohanes, Henok
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The main purpose of this study is to test empirically the impact of working capital management on profitability .To investigate this relationship between these two, the author collected secondary data from 19 manufacturing share companies in Addis Ababa, Ethiopia for the period of 2010 to 2014. Accounts receivable period, inventory holding period and accounts payable period are used as independent working capital investment policy variables. Moreover, cash conversion cycle and current assets to total assets ratio are used as comprehensive measures of working capital investment policy. On the other hand, current liabilities to total assets ratio is used as measure of working capital financing policy. The regression results show inverse relationship between accounts receivable and inventory holding periods with profitability. However there is statistically insignificant relationship between accounts payable period and profitability. The results also show that there exists significant negative relationship between cash Conversion cycle and profitability of the sampled firms. In addition to that there is significant positive relationship between current assets to total assets ratio and profitability measures has been observed. On the other hand, results show that a significant positive relationship between current liabilities to total assets ratio and profitability. To be profitable, firms must try to keep these numbers of days account receivable and inventory turnover days to minimum level. This also helps to minimal the cash conversion cycle also. Since aggressiveness of working capital management investment policies is inversely related to profitability, and aggressive investment policy positively manufacturing related sector with should profitability, the follow conservative financial investment aggressive financing policy in their working capital management

Hamiltonian Magnetohydrodynamics: Lagrangian, Eulerian, and Dynamically Accessible Stability -- Examples with Translation Symmetry

description: Because different constraints are imposed, stability conditions for dissipationless fluids and magnetofluids may take different forms when derived within the Lagrangian, Eulerian (energy-Casimir), or dynamical accessible frameworks. This is in particular the case when flows are present. These differences are explored explicitly by working out in detail two magnetohydrodynamic examples: convection against gravity in a stratified fluid and translationally invariant perturbations of a rotating magnetized plasma pinch. In this second example we show in explicit form how to perform the time-dependent relabeling introduced in Andreussi {\it et al.}\ [Phys.\ Plasmas {\bf20}, 092104 (2013)] that makes it possible to reformulate Eulerian equilibria with flows as Lagrangian equilibria in the relabeled variables. The procedures detailed in the present article provide a paradigm that can be applied to more general plasma configurations and in addition extended to more general plasma descriptions where dissipation is absent.

description: We consider the integer QH state on Riemann surfaces with conical singularities, with the main objective of detecting the effect of the gravitational anomaly directly from the form of the wave function on a singular geometry. We suggest the formula expressing the normalisation factor of the holomorphic state in terms of the regularized zeta determinant on conical surfaces and check this relation for some model geometries. We also comment on possible extensions of this result to the fractional QH states.
