description: This paper will review how I have used writing to process moments of tension or uncertainty with three clients: Eddie, C. F., and Kayla (names changed). In what follows, I will first give a brief background sketch of the client, share parts of a client’s stories from my own reflective writing and then present the core concepts from those theorists who helped me make sense of what had occurred, thus guiding my work with the client. I met each of these clients while working at their high schools on the South Side of Chicago.

description: We report on the first observations of neutron star low-mass X-ray binaries with the Atacama Large Millimeter/submillimeter Array (ALMA) at $\sim$300 GHz. Quasi-simultaneous observations of 4U 1728-34 and 4U 1820-30 were performed at radio (ATCA), infrared (VLT) and X-ray (Swift) frequencies, spanning more than eight decades in frequency coverage. Both sources are detected at high significance with ALMA. The spectral energy distribution of 4U 1728-34 is consistent with synchrotron emission from a jet with a break from optically thick to optically thin emission at 1.3-11.0$\times$10$^{13}$ Hz. This is the third time a jet spectral break has been reported for a neutron star X-ray binary. The radio to mm spectral energy distribution of 4U 1820-30 has significant detections at 5 and 300~GHz. This confirms the presence of radio emission during a soft state for this neutron star and represents the first detection of mm emission during such a state, unambiguously pointing to the presence of a jet. We also report on three additional unrelated sources - showing mm emission - in the ALMA fields of view of 4U 1728-34 and 4U 1820-30.

description: The mass-metallicity relation shows that the galaxies with the lowest mass have the lowest metallicities. As most dwarf galaxies are in group environments, interaction effects such as tides could contribute to this trend. We perform a series of smoothed particle hydrodynamics (SPH) simulations of dwarf galaxies in external tidal fields to examine the effects of tides on their metallicities and metallicity gradients. In our simulated galaxies, gravitational instabilities drive gas inwards and produce centralized star formation and a significant metallicity gradient. Strong tides can contribute to these instabilities, but their primary effect is to strip the outer low-metallicity gas, producing a truncated gas disk with a large metallicity. This suggests that the role of tides on the mass-metallicity relation is to move dwarf galaxies to higher metallicities.

Determinant of Non Performing Loan in Ethiopian Private Commercial Banks: With Emphasis on Manufacturing Sector
Creators: name: Tamiru, Mesay
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The main goal of Ethiopian private commercial banks (EPCB) is to operate profitably in order to maintain its stability and improve growth and sustainability. However, EPCBs experience high levels of non-performing loans. This trend threatens viability and sustainability of banks and hinders the achievement of their goals. This study was aimed at assessing the determinants of non-performing loan growth rate. Specifically the study sought to establish the effect of microeconomic variables (deposit Interest rate, exchange rate and annual inflation rate), bank specific (loan to deposit ratio, credit monitoring and follow-up and loan growth rate) and business characteristic (business profit margin and nature of business). The study was used both primary and secondary data. The study target population comprises six Ethiopian private commercial banks and 12 manufacturing sub sectors (food and beverage and textile). The study adopts a mixed methods research approach by combining documentary analysis (structured review of documents) and in-depth interviews. More specifically, the study reviews the financial records of six private commercial banks in Ethiopia and relevant data on macroeconomic factors considered for the period from the year 2000 to 2015. The sampling of the study includes six private commercial banks, from 16 private commercial banks based on their share of total outstanding loan. The collected panel data is analyzed using descriptive statics, correlation matrix and multiple linear regression analysis. The findings of the study show that business profit margin, deposit interest rate, loan growth rate, loan to deposit ratio, credit monitoring and follow-up and nature of business statistically significant relationship with banks' NPLs. On the other hand, variables like exchange rate and inflation rate were found to be statistically insignificant. Base on the finding the study recommended that Loan growth, business profit margin, loan to deposit ratio and deposit interest rate were significant driver of NPLs, hence focusing and engendering the institution alongside these indicators could reduce the probability of NPL in Ethiopian private commercial banks

description: High-amplitude variability in Young Stellar Objects (YSOs) is usually associated with episodic accretion events. It has not been observed so far in massive YSOs. Here, the high-amplitude variable star sample of ContrerasPeña et al.(2016) has been used to search for highly-variable($Δ$K$\ge$1\,mag) sources coinciding with dense clumps mapped using the 850\mum continuum emission by the ATLASGAL survey. 18 variable sources are centred on the sub-mm clump peaks, and coincide ($$2 mag, significantly higher compared to the mean variability of the entire VVV sample. The light curves of these objects sampled between 2010-2015 display rising, declining, or quasi-periodic behaviour but no clear periodicity. Light-curve analysis using Plavchan method show that the most prominent phased signals have periods of a few hundred days. The nature and time-scale of variations found in 6.7 Ghz methanol maser emission (MME) in massive stars are similar to that of the VYSO light curves. We argue that the origin of the observed variability is episodic accretion. We suggest that the timescale of a few hundred days may represent the frequency at which a spiralling disk feeds dense gas to the young massive star.

description: We present the results of CCD $UBV$ photometric and spectroscopic observations of the open cluster NGC 225. In order to determine the structural parameters of NGC 225, we calculated the stellar density profile in the cluster's field. We estimated the probabilities of the stars being physical members of the cluster using the existing astrometric data. The most likely members of the cluster were used in the determination of the astrophysical parameters of the cluster. We calculated the mean radial velocity of the cluster as $V_{r}=-8.3\pm 5.0$ km s$^{-1}$ from the optical spectra of eight stars in the cluster's field. Using the U-B vs B-V two-colour diagram and UV excesses of the F-G type main-sequence stars, the reddening and metallicity of NGC 225 were inferred as $E(B-V)=0.151\pm 0.047$ mag and $[Fe/H]=-0.11\pm 0.01$ dex, respectively. We fitted the colour-magnitude diagrams of NGC 225 with the PARSEC isochrones and derived the distance modulus, distance and age of the cluster as $μ_{V}=9.3\pm 0.07$ mag, d=585$\pm$20 pc and $t=900\pm 100$ Myr, respectively. We also estimated the galactic orbital parameters and space velocity components of the cluster and found that the cluster has a slightly eccentric orbit of $e=0.07\pm 0.01$ and an orbital period of $P_{orb}= 255\pm 5$ Myr.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Capital structure decisions are among the most important and crucial decisions for any business because of their effect on the value and cost of the company. In this paper, an attempt has been made to examine the relevance of theoretical internal (firm level) factors determine capital structure of manufacturing share companies in Addis Ababa, Ethiopia. To seek answers to these questions, seven explanatory variables; tangibility, non-tax shields, growth, earning volatility, profitability, age and size of the firm were regressed against the dependent variables of total debt ratio, short term ratio and long term debt ratio. In connection of this, a sample of 12 companies were take and secondary data was collected from audited financial statements of selected companies for the period of five years (1996- 2002EC). Stratified sampling design was employed and companies were selected based on simple random to represent different industry sectors (strata) within manufacturing share companies. Data was then analyzed on quantitative basis using multivariate OLS regression. The results show that tangibility, non debt tax shields, earning volatility, profitability, and size of the firm variables are the significant determinants of capital structure of Addis Ababa manufacturing share companies at least one out of the three models for capital structure employed in the study. While no clear and statistical proved relation are obtained for the variables growth of the firm and age of the firm in any of the capital structure models

description: Aims Seeds are usually classified as short- or long-term persistent. It is still hardly understood how environmental conditions influence seed persistence. The study aimed to monitor the long-term effects of different moisture and substrate on seed persistence. Methods Seeds of three Rumex species buried in autumn 2009 in combinations of moisture and substrate were exhumed in spring 2015 and 2021 to test their persistence in the soil after 5.5 and 11.5 years, respectively. Long-term persistence data were compared with data from previous short-term experiment for the same species and environmental conditions reported in Abedi et al. (Plant Soil 374:485-495, 2014). Results No seeds of R. acetosa were found viable after 1.5 years. Seeds of R. acetosella retained viability after 11.5 years mostly in dry-loam (~ 60%) and moist-sand (~ 25%) test conditions and moisture levels were identified as the main driver. R. maritimus retained ≥ 80% viability in moist and wet test conditions and > 40% in the dry test conditions. Conclusions For one (R. acetosella) of the three investigated species, the classification of soil seed bank type depended on environmental conditions, emphasizing the need to introduce a more detailed classification scheme for soil seed persistence and to include the information about extrinsic parameters in databases. However, in the other two species with transient (R. acetosa) and long-term persistent (R. maritimus) seed banks, there are rather intrinsic parameters that affect seed viability. Hence, both site-specific environmental factors as well as seed germination traits need full consideration in the classification of future soil seed bank studies.
In-Out Formalism for One-Loop Effective Actions in QED and Gravity

description: The in-out formalism is a systematic and powerful method for finding the effective actions in an electromagnetic field and a curved spacetime provided that the field equation has explicitly known solutions. The effective action becomes complex when pairs of charged particles are produced due to an electric field and curved spacetime. This may lead to a conjecture of one-to-one correspondence between the vacuum polarization (real part) and the vacuum persistence (imaginary part). We illustrate the one-loop effective action in a constant electric field in a Minkowski spacetime and in a uniform electric field in a two-dimensional (anti-) de sitter space.

description: The "Magnificent Seven" (M7) are a group of radio-quiet Isolated Neutron Stars (INSs) discovered in the soft X-rays through their purely thermal surface emission. Owing to the large inferred magnetic fields ($B\approx 10^{13}$ G), radiation from these sources is expected to be substantially polarised, independently on the mechanism actually responsible for the thermal emission. A large observed polarisation degree is, however, expected only if quantum-electrodynamics (QED) polarisation effects are present in the magnetised vacuum around the star. The detection of a strongly linearly polarised signal would therefore provide the first observational evidence of QED effects in the strong-field regime. While polarisation measurements in the soft X-rays are not feasible yet, optical polarisation measurements are within reach also for quite faint targets, like the M7 which have optical counterparts with magnitudes $\approx 26$--$28$. Here, we report on the measurement of optical linear polarisation for the prototype, and brightest member, of the class, RX\, J1856.5$-$3754 ($V\sim 25.5$), the first ever for one of the M7, obtained with the Very Large Telescope. We measured a polarisation degree $\mathrm{P.D.} =16.43\% \pm5.26\%$ and a polarisation position angle $\mathrm{P.A.}=145\fdg39\pm9\fdg44$, computed east of the North Celestial Meridian. The $\mathrm{P.D.}$ that we derive is large enough to support the presence of vacuum birefringence, as predicted by QED.

description: The paper examines the tax compliance costs of the individual taxpayers in Addis Ababa. One research question and one hypothesis were investigated in this study: (RQ) compliance costs of the individual income tax system borne directly by the taxpayers themselves, including both the time spent and pecuniary expenditures and (H) The compliance costs of individual income tax are relatively low - in terms of their costs per individual: especially costs of time and monetary costs. The survey was conducted to a total of 170 individual income tax payers and questionnaires were distributed to those individual taxpayers in the administrative city of Addis Ababa in Ethiopia. A total of 103 useable responses were received and used for the final data analysis. The findings from the survey provide pertinent and useful insights about the compliance costs of Addis Ababa individual taxpayers. The results of the study indicate that the highest time spend was on learning tax rules. The average values per tax payers were 168.83 ETB and the average times spent by tax payers for filing their tax return were 5.17hrs. In all, the study found that the compliance costs of individual taxpayers in Addis Ababa were relatively low in term of the total monetary value Keywords: compliance cost, income tax, Addis Ababa

description: Some features of the field induced phase transition accompanied by the vacuum creation of an electron-positron plasma (EPP) in strong time-dependent electric fields have been discussed in the work [1] in the domain of the tunneling mechanism ($ω\ll m$, where $ω$ is the characteristic frequency of the external field and $m$ is the electron mass). In the present contribution the features of the this process will be considered in the few photon domain where $ω\sim m$. We observe a narrowing of the transient domain of the fast oscillations and, mainly, a considerable growth of the effectiveness of the EPP production. Under these circumstances, we see an increase of the effectiveness of the EPP creation in the particular case of a bifrequent excitation, where both mechanisms (tunneling and few photon) act simultaneously [2,3].

Customs Valuation System in Ethiopia
Creators: name: Seifu, Tenkir
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: The study assessed the customs valuation system applied in Ethiopia and investigated the existing problems in the system. The methods adopted in the study include documentary analysis, in-depth interview and self administered questionnaires. The results suggested that the Customs Valuation System in Ethiopia does not provide fair, neutral and uniform valuation and does not effectively protect traders from risk of arbitrary valuation by the customs officers. There is also risk of revenue loss to the government due to underinvoicing of imports by the traders since controlling mechanisms such as Post Clearance Audit (PCA) are not adequately developed. Therefore, the Government of Ethiopia needs to strengthen the controlling mechanisms within the customs valuation system since duties and taxes on foreign trade contribute the significant portion of its tax and duty revenues

description: The joint use of accurate near- and mid-infrared photometry from the 2MASS and WISE catalogues has allowed the variations of the extinction law and the dust grain size distribution in high Galactic latitudes (|b|>50) at distances up to 3 kpc from the Galactic midplane to be analyzed. The modified method of extrapolation of the extinction law applied to clump giants has turned out to be efficient for separating the spatial variations of the sample composition, metallicity, reddening, and properties of the medium. The detected spatial variations of the coefficients E(H-W1)/E(H-Ks), E(H-W2)/E(H-Ks), and E(H-W3)/E(H-Ks) are similar for all high latitudes and depend only on the distance from the Galactic midplane. The ratio of short-wavelength extinction to long-wavelength one everywhere outside the Galactic disk has been found to be smaller than that in the disk and, accordingly, the mean dust grain size is larger, while the grain size distribution in the range 0.5-11 microns is shifted toward coarse dust. Specifically, the mean grain size initially increases sharply with distance from the Galactic midplane, then decreases gradually, approaching a value typical of the disk at $|Z|\approx2.4$ kpc, and, further out, stabilizes or may increase again. The coefficients under consideration change with coordinate $Z$ with a period of about 1312\pm40 pc, coinciding every 656\pm20 pc to the south and the north and showing a significant anticorrelation between their values in the southern and northern hemispheres at intermediate Z. Thus, there exists a unified large-scale periodic structure of the interstellar medium at high latitudes within at least 5 kpc. The same periodic variations have also been found for the extinction coefficient Rv within 600 pc of the Galactic midplane through the reduction of different photometric data for stars of different classes.

Corporate Capital Structure and its Impact on Profitability: Evidence from Manufacturing firms in Ethiopia
Creators: name: Birassa, Frezewd
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The aim of this paper is to provide large sample evidence on capital structure and its impact on profitability using a new database of large tax payer manufacturing firms in Ethiopia. The study employs a panel data regression analysis. The dataset comprises twenty four large tax payer manufacturing share companies covering a five-year period (2010-2014 G.C.) using firm level accounting data. Within what is referred to as capital structure the researcher is able to examine the relationship between capital structure variables and profitability. Most sample firms concentrate their borrowing in only one of these debt types especially short term debt finances and this debt specialization persists overtime. It is also clear from the study that short-term debt to total liability, long-term debt capitalization ratio and interest coverage ratio showed positive and significant impact on profitability. Other constituted variables i.e. debt ratio and debt to equity ratio found to be insignificant regarding their impact on profitability of sample firms. Therefore, no significant linear dependence was detected for debt ratio and debt to equity ratio versus profitability

Using this representation and the properties of fundamental solution, the Cauchy problem and the basic problems in half-strip and rectangular domains are studied. For Cauchy problem the theorems of existence and uniqueness of solution are proved, and the explicit form of solution is constructed. The solutions of the investigated problems are constructed in terms of the appropriate Green functions, which are also constructed an explicit form.

Scale-invariant radio jets and varying black hole spin

description: Compact radio cores associated with relativistic jets are often observed in both active galactic nuclei and X-ray binaries. Their radiative properties follow some general scaling laws which primarily depend on their masses and accretion rates. However, it has been suggested that the black hole spin can also strongly influence the power and radio flux of these. Here, we attempt to estimate the dependency of the radio luminosity of steady jets launched by accretion disks on black hole mass, accretion rate and spin using numerical simulations. We make use of 3D GRMHD simulations of accretion disks around low-luminosity black holes in which the jet radio emission is produced by the jet sheath. We find that the radio flux increases roughly by a factor of 6 as the back hole spin increases from a~0 to a=0.98. This is comparable to the increase in accretion power with spin, meaning that the ratio between radio jet and accretion power is hardly changing. Although our jet spine power scales as expected for the Blandford-Znajek process, the dependency of jet radio luminosity on the black hole spin is somewhat weaker. Also weakly rotating black holes can produce visible radio jets. The overall scaling of the radio emission with black hole mass and accretion rate is consistent with the scale-invariant analytical models used to explain the fundamental plane of black hole activity. Spin does not introduce a significant scatter in this model. The jet-sheath model can describe well resolved accreting systems, such as SgrA* and M87, as well as the general scaling behavior of low-luminosity black holes. Hence the model should be applicable to a wide range of radio jets in sub-Eddington black holes. The black hole spin has an effect on the production of visible radio jet, but it may not be the main driver to produce visible radio jets. An extension of our findings to powerful quasars remains speculative.

description: Audit quality is a very debatable topic in the area of auditing following the fall of giant companies in the West. One of the issues that gained momentum has been to analyze the external audit quality and the various audit firm-client relationships. The purpose of this study is to investigate the determinants of external audit quality proxied by discretionary (abnormal) accrual based on audit firm specific attributes that are considered vital by regulatory and professional bodies to properly monitor the external audit profession and to maintain trust among the various stakeholders in Ethiopian manufacturing share companies. In light of this objective the study adopted quantitative method of research approaches to test a series research hypothesis. Specifically, the study used documentary analysis of companies' audited financial statements and personal inquiry with audit directors/officials of audit firms. Then companies were selected based on simple random sampling method to avoid biases and represent firms within manufacturing companies. Consequently, the study selected a sample of twelve (12) companies for the period of five years (2009-2013) with the total of 60 observations. The results of panel least square regression analysis show that audit firm industry specialization and certified audit professionals ratio have statistically significant and positive relationship with manufacturing share companies' external audit quality. On the other hand, the joint provision of audit and non-audit service has a negative and statistically significant relationship with manufacturing share companies' external audit quality. However, the relationship for audit firm size and audit firm tenure is found to be statistically insignificant. Therefore, this is a clear signal to all manufacturing share companies in Ethiopia that they cannot ignore audit firm characteristics while hiring of an audit firm for their audit service. Keywords: external audit quality, audit-firm specific attributes, earning management discretionary (abnormal) accrual.

description: The number of elderly population is increasing significantly. The elderly living independently need serious attention as in some cases the elderly people are also found dead in their places. Therefore, it is crucial to assist older adults to live a safer independent life. The increasing cost of nursing care and the shortage of health-care workers increase the demand of home-based assisted living in recent time. Thus, home-based health care for elderly people has become an active research domain, among which abnormal activity detection attracts most attention. My thesis aims to provide effective solutions to support independent living for elderly, which consists the following five works. The first work presents an extensive survey to highlight those technologies for human activity and anomalous behaviour detection which are essential in elderly care. It also discusses the current research trends, their outcomes and effects in elderly care. The second work predicts human activities from sensor data. I propose and show the effectiveness of employing a new combination of deep learning (DL) methods for human activity recognition (HAR). Specifically, I propose a hybrid architecture which features a combination of Convolutional neural networks (CNN) and Long short-term Memory (LSTM) networks for HAR task. The model is tested on UCI_HAR_dataset which is a benchmark dataset and comprises of accelerometer and gyroscope data obtained from a smartphone. The third work predicts human activities from video. I use CNN model to predict human activities from Wiezmann Dataset. Specifically, I employ transfer learning to get deep image features and train machine learning classifiers. The fourth work detects human anomalous behaviour. I use multi-view learning methods to detect human fall. I introduce 3 methods for feature fusion for multiview learning to leverage the inadequacy of single-view learning. I use co-training methods to train each view alternately for better learning. The fifth work surveys the privacy and security issues that may occur in home care systems which require connected devices exchanging data. Data collection involves information exchange among the connected devices. Therefore, security examination and requirement is important aspect from the data collection perspective. All the algorithms proposed in this thesis have been validated and evaluated through extensive experiments on publicly available dataset. The results have demonstrated that the proposed algorithms significantly outperform the comparable models in the existing studies in terms of effectively predicting human activities and anomalous behaviour, which are essential for elderly care.

description: For various polymers with different topological structures we numerically evaluate the mean-square radius of gyration and the hydrodynamic radius systematically through simulation. We call polymers with nontrivial topology topological polymers. We evaluate the two quantities both for ideal and real chain models and show that the ratios of the quantities among different topological types do not depend on the existence of excluded volume if the topological polymers have only up to trivalent vertices, as far as the polymers investigated. We also evaluate the ratio of the gyration radius to the hydrodynamic radius, which we expect to be universal from the viewpoint of renormalization group. Furthermore, we show that the short-distance intrachain correlation is much enhanced for topological polymers expressed with complex graphs.

description: We set up a formalism, within the antenna subtraction framework, for computing the production of a massive quark-antiquark pair in electron positron collisions at next-to-next-to-leading order in the coupling $α_s$ of quantum chromodynamics at the differential level. Our formalism applies to the calculation of any infrared-safe observable. We apply this set-up to the production of top-quark top antiquark pairs in the continuum. We compute the production cross section and several distributions. We determine, in particular, the top-quark forward-backward asymmetry at order $α_s^2$. Our result agrees with previous computations of this observable.

description: In general, business environment is becoming more complex and competitive in nature. Companies in different industries are upcoming with a number of differentiated products and characterized by high quality with the level best required level of innovative skills. These all devotions and efforts are aimed of existing successfully in the industry they belong. Walsh et al, (2005) argue that, appropriate design and use of MCS elements have a direct relationship with the success of the organization in competitive market environment. This paper is aimed at assessing BGI Ethiopia on three selected elements of management control system specifically, result control group, evaluating the practice through identifying and relying on theoretical propositions derived from the literature and finally, to recommend on how to improve these elements in their organization. In this research, an exploratory case study approach along a qualitative research method for collecting and analyzing the data are used. The case chosen in this study is BGI Ethiopia which is one of the brewery companies in the country. The empirical findings were analyzed through identifying themes from the data, by relying on theoretical propositions derived from the literature. The results show the following facts: Strategy Planning: the strategic planning practice being used by BGI Ethiopia is in line with the theoretical propositions derived from the literature and control by using goals is highly emphasized. Performance Measurement and Evaluation: The new performance measurement literature indicates, performance measurement system should in corporate any financial and non- financial measure that provides incremental information on managerial efforts. However, BGI Ethiopia's approach to performance measurement is supplementing extensive traditional financial measure less mix of non – financial measures. The reward and incentive are not used very significantly. The system in use extensively consists of monetary rewards; both short term and long term incentives and do not use non-monetary incentives in greater extent to motivate its employees and the system seems incapable of achieving result control, since they influence employees' actions by taking rewards to desired results

description: Topology optimization of a waveguide-cavity structure in phononic crystals for designing narrow band filters under the given operating frequencies is presented in this paper. We show that it is possible to obtain an ultra-high-Q filter by only optimizing the cavity topology without introducing any other coupling medium. The optimized cavity with highly symmetric resonance can be utilized as the multi-channel filter, raising filter and T-splitter. In addition, most optimized high-Q filters have the Fano resonances near the resonant frequencies. Furthermore, our filter optimization based on the waveguide and cavity, and our simple illustration of a computational approach to wave control in phononic crystals can be extended and applied to design other acoustic devices or even opto-mechanical devices.

description: We disprove the conjecture that distributional chaos of type 3 (briefly, DC3) is iteration invariant and show that a slightly strengthened definition, denoted by DC2$\frac{1}{2}$, is preserved under iteration, i.e. $f^n$ is DC2$\frac{1}{2}$ if and only if $f$ is too. Unlike DC3, DC2$\frac{1}{2}$ is also conjugacy invariant and implies Li-Yorke chaos. The definition of DC2$\frac{1}{2}$ is the following: a pair $(x,y)$ is DC2$\frac{1}{2}$ iff $Φ_{(x,y)}(0)

description: The development of any nation depends on the ability of the government to generate sufficient amount of revenue from its own internal source of finance. Tax is the most efficient and effective tools of fiscal policy in the world through which a government is able to supply a variety of social and welfare services. Many developing countries face fiscal deficit due to low tax collection performance. Similarly, Ethiopian tax collection performance is low as compared to other sub-Saharan African countries and the trend of these taxes not consistent. The main objective of the study was to identify determinants of tax revenue performance in Ethiopia using time series data covering period from1980-2015. The variables used in the study were inflation rate, exchange rate, unemployment rate, foreign direct investment, urbanization rate as explanatory variables to explain the explained variable of tax revenue performance. Multiple regression model and Vector error correction model (VECM) have been employed to analyze the long run and short run relationship for the analysis and test the hypotheses developed using ordinary least square. The stability of the data is checked and all the data are stationary by differencing, beside all the CLRM assumptions were tested and none of the assumptions violated in the study. Accordingly, the result of the regression model revealed that urbanization rate, inflation rate and foreign direct investment have significant positive relationship with tax revenue performance, whereas unemployment rate has significant negative relationship with tax revenue performance in the long run. But exchange rate has negative insignificant effect in the long run .Unlike the long run; only exchange rate has a significant positive effect on tax revenue performance in the short. Finally, the study forwarded recommendation that enhance tax revenue performance to incorporating all responsible organs under the tax system, improving labor market to bring unemployment back down ,deepening currently followed market economy and expand formal settlement and exhaustively working to track foreign investment. Key words: Tax revenue performance, Unemployment rate, Inflation rate, Urbanization rate, Exchange rate and Foreign direct investment
