description: The spectrum of a quasar contains important information about its properties. Thus, it can be expected that two quasars with similar spectra will have similar properties, but just how similar has not before been quantified. Here we compare the ultraviolet spectra of a sample of 5553 quasars from Data Release 7 of the Sloan Digital Sky Survey, focusing on the $1350$ Å\ $\leq λ\leq 2900$ Å\ rest-frame region which contains prominent emission lines from \SiIV, O IV], \CIV, \CIII, and \MgII\ species. We use principal component analysis to determine the dominant components of spectral variation, as well as to quantitatively measure spectral similarity. As suggested by both the Baldwin effect and modified Baldwin effect, quasars with similar spectra have similar properties: bolometric luminosity, Eddington fraction, and black hole mass. The latter two quantities are calculated from the luminosity in conjunction with spectral features, and the variation between quasars with virtually identical spectra (which we call doppelgängers) is driven by the variance in the luminosity plus measurement uncertainties. In the doppelgangers the luminosity differences show 1$σ$ uncertainties of 57\% (or 0.63 magnitudes) and $\sim$70\% 1$σ$ uncertainties for mass and Eddington fraction. Much of the difference in luminosities may be attributable to time lags between the spectral lines and the continuum. Furthermore, we find that suggestions that the mostly highly accreting quasars should be better standard candles than other quasars are not bourne out for doppelgangers. Finally, we discuss the implications for using quasars as cosmological probes and the nature of the first two spectral principal components.

Comparison of the topical effect of Aloe vera and violet with hydroxyzine on dry skin of hemodialysis patients (A crossover interventional trial)
Publisher: name: Birjand University of Medical Sciences
Year: 2022

description: Background and Aims: Dry skin is one of the most common skin complications associated with chronic renal failure in hemodialysis patients. Aloe vera gel and Violet oil can be effective in improving the symptoms of dryness through special mechanisms. Therefore, this study aimed to compare the topical effect of Aloe vera and Violet with hydroxyzine on dry skin of hemodialysis patients.\nMaterials and Methods: In this randomized crossover interventional trial, 36 people were selected according to the inclusion criteria and available sampling method. Following that, they were divided into three groups (12 cases per group) of A, B, and C by simple random sampling. The study consisted of three two-week intervention periods and two wash-out periods for one week. By performing a random allocation, all three groups received one of the interventions, including Aloe vera gel, Violet oil, or hydroxyzine tablets in each period. Data were collected using the VAS tool before and after the interventions by the co-researcher. The obtained data were then analyzed in SPSS software (version 16). Furthermore, SAS software (version 9.2) was also used to analyze crossover effects including period and carry-over effects. A P-value less than 0.05 was considered statistically significant.\nResults: The results showed that in the first and third periods, in all three treatments, the mean score of dryness intensity had a statistically significant decrease before and after the intervention (P<0.05); however, this reduction in the second period was not significant in none of the treatments (P>0.05). In addition, the effect of all three treatments showed no statistical significance on the severity of dryness in patients after the intervention (P>0.05).\nConclusion: All three treatments can improve the symptoms of skin dryness as equipotent in hemodialysis patients. However, further research is needed to confirm the results of this study.\n

description: The increasing predominance of cognitive deficits following neurological conditions such as dementia and stroke is a major concern in Portugal. Cognitive rehabilitation has been shown to be fundamental to alleviate some of the deficits, but it is not always customized to the specific profile of each patient. More critically, patients typically do not have rehabilitation while they are in the waiting list or after discharge. One way to address these limitations is using interactive technologies specifically designed for cognitive rehabilitation. Their digital nature allows the customization of parameters enabling personalization and adaptation to each patient's profile, as well as the possibility of quantification of performance. In addition, these tools have the potential to be used at home, allowing patients to continue their rehabilitation and being monitored remotely, alleviating the burden of institutionalization for both patients and healthcare systems. However, before proposing novel technologies, it is imperative to understand current practices, needs, preferences and expectations of health professionals in this domain. For this purpose, we developed an online questionnaire that was distributed among health professionals in Portugal. 116 participants have responded, with 35% reporting having experience in the use of interactive technologies for cognitive rehabilitation. Our results show that health professionals that use these technologies mainly value ease of interaction, diversity of activities, task personalization to the patient's cognitive profile, and adaptation based on performance. These and other insights will be used to inform the development of novel tools for cognitive rehabilitation in clinical and home settings.

metal-poor DLA system

description: We present the detection of D I lines in the metal poor ([O/H] =
 −1.73 ± 0.02 ) sub-Damped Lyman-α system (log N(H I) = 19.310 ± 0.005
 ) at zabs = 3.42 towards the quasar J1332+0052. From simultaneous
 fitting the Lyman series of H I and D I as well as metal lines observed
 at high signal-to-noise and high spectral resolution with the Ultraviolet
 and Visual Echelle Spectrograph on the Very Large Telescope and High
 Resolution Echelle Spectrometer on W.M. Keck Observatory, we measure 105×D I/H I= 2.388 ± 0.112 (stat + syst). Given the expected negligible ionisation corrections and the lack of deuterium astration at this metallicity, this ratio provides a direct measurement of the primordial
 deuterium abundance. Together with previous similar measurements, we
 pin down the primordial deuterium abundance to 105×(D/H)p= 2.541 ±
 0.025, in remarkable agreement with
 the Standard Model value (to within 1.1σ).

description: The protoplanetary disk around the GGTau A binary system is so far one of the most studied young circumbinary disk. Observations of the dust continuum emission at sub-mm/mm wavelengths detected a dust ring located between 200AU and 300AU from the center of mass of the system. If the disk and the binary orbit are coplanar, given the observed projected separation of the stars in the binary system, the classical theory of tidal interaction between a binary system and its circumbinary disk predicts a truncation radius which is significantly smaller than the measured inner radius of the mm-sized dust ring. We investigate the origin of this dust ring structure in the GG Tau A disk, test whether the interaction between the binary and the disk can produce a dust trap at the location of the observed ring, and discuss an alternative scenario which invokes a misalignment between the disk and the stellar orbital planes. We run a set of hydrodynamical simulations for an orbit consistent with the astrometric solutions for the GG Tau A stellar proper motions, and for different disk temperature and viscosities. We then apply a dust evolution model in post-processing in order to to retrieve the distribution of mm-sized grains. Comparing models and observations, we show that, if the binary orbit and the disk were coplanar,the tidal truncation of the circumbinary disk would occur at a radius that is too small compared to the inner edge inferred by the dust observations, and that the pressure bump and the dust ring in the models would be located at <150AU from the center of mass of the stellar system. This shows that the GG Tau A disk cannot be coplanar with the binary orbital plane. We also discuss the viability of the misaligned disk scenario, suggesting that in order for dust trapping to occur at the observed radius, the disk and orbital plane must be misaligned by an angle of about 25 degrees.

description: We describe a novel, very fast and robust, directed search incoherent method for periodic gravitational waves (GWs) from neutron stars in binary systems. As directed search, we assume the source sky position to be known with enough accuracy, but all other parameters are supposed to be unknown. We exploit the frequency-modulation due to source orbital motion to unveil the signal signature by commencing from a collection of time and frequency peaks. We validate our pipeline adding 131 artificial continuous GW signals from pulsars in binary systems to simulated detector Gaussian noise, characterized by a power spectral density Sh = 4x10^-24 Hz^-1/2 in the frequency interval [70, 200] Hz, which is overall commensurate with the advanced detector design sensitivities. The pipeline detected 128 signals, and the weakest signal injected and detected has a GW strain amplitude of ~10^-24, assuming one month of gapless data collected by a single advanced detector. We also provide sensitivity estimations, which show that, for a single- detector data covering one month of observation time, depending on the source orbital Doppler modulation, we can detect signals with an amplitude of ~7x10^-25. By using three detectors, and one year of data, we would easily gain more than a factor 3 in sensitivity, translating into being able to detect weaker signals. We also discuss the parameter estimate proficiency of our method, as well as computational budget, which is extremely cheap. In fact, sifting one month of single-detector data and 131 Hz-wide frequency range takes roughly 2.4 CPU hours. Due to the high computational speed, the current procedure can be readily applied in ally-sky schemes, sieving in parallel as many sky positions as permitted by the available computational power.

description: Given an $n$-dimensional manifold $N$ with an affine connection $D$, we show that the associated Patterson-Walker metric $g$ on $T^*N$ admits a global and explicit Fefferman-Graham ambient metric. This provides a new and large class of conformal structures which are generically not conformally Einstein but for which the ambient metric exists to all orders and can be realized in a natural and explicit way. In particular, it follows that Patterson-Walker metrics have vanishing Fefferman-Graham obstruction tensors. As an application of the concrete ambient metric realization we show in addition that Patterson-Walker metrics have vanishing Q-curvature.

description: We study the dynamics of Brownian particles in a heterogeneous one-dimensional medium with a spatially-dependent diffusion coefficient of the form $D(x)\sim |x|^c$, at constant temperature. The particle's probability distribution function (PDF) is calculated both analytically, by solving Fick's diffusion equation, and from numerical simulations of the underdamped Langevin equation. At large times, the PDFs calculated by both approaches yield identical results, corresponding to subdiffusion for $c<0$, and superdiffusion for $01$, the diffusion equation predicts that the particles accelerate. Here, we show that this phenomenon, previously considered in several works as an illustration for the possible dramatic effects of spatially-dependent thermal noise, is unphysical. We argue that in an isothermal medium, the motion cannot exceed the ballistic limit ($\left\langle x^2\right\rangle \sim t^2$). The ballistic limit is reached when the friction coefficient drops sufficiently fast at large distances from the origin, and is correctly captured by Langevin's equation.

Perception of Auditors on Mandatory Audit firm Rotation and its Effect on Auditor's Independence in Ethiopia
Creators: name: Taddese, Tesfamichael
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This study was conducted on mandatory audit firm rotation and its effect on auditor independence in Ethiopia as the perception on external auditors. Factors affecting the ability of auditors to remain independent include long audit tenure, financial dependence on a single audit client, non-audit services provided to audit clients and ex-auditor employment with an audit client. It is therefore timely to examine the importance of auditor independence in the provision of reliable and credible financial information. The study used 5 point likert scale questionnaire and simple random sampling techniques were given to a sample of 84 external auditors who are found at different level and to examine auditors' perceptions of the effect of mandatory audit firm rotation on auditor independence. The results of the study revealed that 80.3% of auditors agreed that MAFR could safeguard auditor independence. The results also reveal that there is a significant relationship between mandatory audit firm rotation and auditor independence. Analyses of variance (ANOVA) were also conducted to test for the possibility of confounding effects arising from participants' background and experience. None of these variables were found to have a confounding effect on the experimental results. The results also disclose that the adoption of rotation rules wasn't given enough attention among the auditing firms in Ethiopia. Further research should be considered regarding other possible recommendations for enhancing the independence of auditors. Some examples include, appointment of company auditors by the state or an independent oversight body, and introduce a government approved body to verify the auditors' work year after year to ensure they are carrying out their duties to their full capability.

description: Men’s friendships have long been considered ‘activity-based’ and largely void of the trust and intimacy that women friends share – but recent research suggests this is changing. In this thesis, I draw on data from individual interviews with fourteen pairs of fathers and sons (n=28) to explore what this change looks like, why it has come about and what this says about the transformation of masculinity more broadly. Ultimately, I argue that the increasing influence of feminism, LGBTQIA+ rights and mental health discourse has destabilised traditional masculine norms that relate to friendship, allowing men to be more caring, expressive and intimate.

Year: 2015

description: Liquidity is increasingly important in the face of high funding costs. The main objective of this paper was to study and identify the main determinates of Ethiopian commercial banks liquidity and its impact on profitability. In order to achieve the objective a secondary sources of data were collected from eight commercial banks in the sample covering the period from 2002/03 to 2013/14 and analyzed themwith panel data regression analysis. The results of regression analysis showed that Bank size and Loan growth had negative and statistically significant impact on banks liquidity measured by Liquide asset to total Asset. Real growth rate of gross domestic product on the basis price level, Interest rate on lending ,Non-performing loans in the total volume of loans, Bank size, Actual reserve ration and short term interest rate had positive and statistically. Among the statistically significant factors affecting banks liquidity bank size had positive and statistically significant impact on Profitability whereas, growth rate of gross domestic product on the basis price level, Actual reserve rate and Non-performing loans in the total volume of loans had negative impact on profitability. Therefore, the impact of bank liquidity on commercial bank profitability was non-linear. Bank size, and Adjusting the liquidity position with better strategy for managing credit risk (NPL) has positive impact on profitability. Also, the study suggest that commercial banks in Ethiopia should encouraged to conduct research on liquidity issues faced by banks, identify their optimal level of liquid asset holdings by weighting the marginal costs and marginal benefits of holding. Since, commercial banks do not respond to the dynamics of economic growth which can be taken as an indication of ineffective competition and efficiency in the Banking sector, NBE should come out with strict rules and regulations for control mechanism of firm specific and macroeconomic factors.

description: This study was conducted on the Ethiopian private auditor's professional responsibilities and legal liability, in comparison with those developed countries auditing principles and standards. The paper tested the responsibilities of the management and the auditors with regard to preparation of the financial statements and subsequent discovery to misstatements to the audited financial statements in Ethiopia. The paper qualitatively estimated to what extent private auditors exercise their professional and legal responsibilities. The paper also tested the legal consequences on auditors as a result of those violated professional and legal responsibilities. Besides it tested that to which auditors are liable for the violation of contractual and statutory responsibilities. Further the study tried to explore the constraints related to private auditors in exercising their responsibilities. Finally, not the least the paper explored some cases related to Ethiopia private auditors' practices

description: Proton-conducting ceramic tubular membranes have been characterized via a fourpoint bending technique to assess their linear behaviour and mechanical properties. Different testing conditions have been investigated, varying parameters such as temperature, gas atmosphere composition and time of exposure to the latter conditions to determine the effect of relevant operating parameters on the mechanical reliability of the aforementioned components. The tests were conducted in air at room temperature and in reducing conditions at 650°C upon short-term exposure and 1000 hours of ageing in the same atmosphere and temperature. The tubular proton-conducting ceramic membranes showed satisfactory mechanical performance in all the conditions mentioned above. A mild decrease in the mechanical properties can be observed upon exposure to higher temperatures due to softening of the metallic phase present in the support and reduced fracture resistance. Long-term exposure to reducing conditions at high temperatures did not induce any further reduction in the mechanical performance, indicating that no evident degradation phenomena affected the microstructure and chemical characteristics of the specimens. This finding was further confirmed by microstructural and chemical characterization. It can be concluded that the tubular membranes object of this study ensure satisfactory mechanical reliability and are not affected by significant degradation phenomena in the investigated conditions.

description: What is the role of coherence in determining the distribution of work done on a quantum system? We approach this question from an operational perspective and consider a setup in which the internal energy of a closed system is recorded by a quantum detector before and after the system is acted upon by an external drive. We find that the resulting work distribution depends on the initial state of the detector as well as on the choice of the final measurement. We consider two complementary measurement schemes, both of which show clear signatures of quantum interference. We specifically discuss how to implement these schemes in the circuit QED architecture, using an artificial atom as the system and a quantized mode of the electromagnetic field as the detector. Different measurement schemes can be realized by preparing the field either in a superposition of Fock states or in a coherent state and exploiting state-of-the art techniques for the characterization of microwave radiation at the quantum level. More generally, the single bosonic mode we utilize is arguably the minimal quantum detector capable of capturing the complementary aspects of the work distribution discussed here.

description: We provide a criterion in order to decide the stability of non-degenerate equilibrium states of completely integrable systems. More precisely, given a Hamilton-Poisson realization of a completely integrable system generated by a smooth $n-$ dimensional vector field, $X$, and a non-degenerate regular (in the Poisson sense) equilibrium state, $\overline{x}_e$, we define a scalar quantity, $\mathcal{I}_{X}(\overline{x}_e)$, whose sign determines the stability of the equilibrium. Moreover, if $\mathcal{I}_{X}(\overline{x}_e)>0$, then around $\overline{x}_e$ there exist one-parameter families of periodic orbits shrinking to $\{\overline{x}_e \}$, whose periods approach $2π/\sqrt{\mathcal{I}_{X}(\overline{x}_e)}$ as the parameter goes to zero. The theoretical results are illustrated in the case of the Rikitake dynamical system.

description: The purpose of this study is to examine theimpact of financial performances on presidents' compensation in Ethiopian commercial banks. In light of this objective the study adopted mixed research approach using 8 commercial banks operate in Ethiopia.These banksare operatesin the industry for the last 10 years i.e. from 2004 up to 2013. Thus, the study used a total of 80 observations. The study used documentary reviews of annual reports and in-depth interviews to test stated research hypotheses and to answer the research questions. The data was mainly analyzed on quantitative basis using Eviews 6 software, OLS regression analysis. Further, arguments were made by the support of in-depth interviews.The results showed that performance of banks have no impact on president compensation of Ethiopian commercial banks. However, the result showed a significance negative relationship between ownership and president compensation. In addition, the study founds a positive significance relationship between bank size and president compensation. Furthermore, the study found a negative insignificance relationship between capital adequacy, inflation and president compensation.The study also found that one period lagged value of compensation is the main determinants of compensation. Thus, commercial banks in Ethiopia should give considerations for performance and inflation to align share holder interest with that of president. Keywords: performance, president compensation, ownership, bank size, capital adequacy ratio, inflation, lagged value and share holder interest

description: We investigate the quantum phase transitions of spin systems in one and two dimensions by employing trace distance and multipartite entanglement along with real-space quantum renormalization group method. As illustration examples, a one-dimensional and a two-dimensional $XY$ models are considered. It is shown that the quantum phase transitions of these spin-chain systems can be revealed by the singular behaviors of the first derivatives of renormalized trace distance and multipartite entanglement in the thermodynamics limit. Moreover, we find the renormalized trace distance and multipartite entanglement obey certain universal exponential-type scaling laws in the vicinity of the quantum critical points.

Dynamical BBH formation and disruption: implications for gravitational waves
Creators: name: Pina, Daniel Marín
name: Gieles, Mark
Publisher: name: Zenodo
Year: 2023

description: In the central regions of globular clusters, black hole binaries (BBH) are assembled dynamically in three-body interactions. The BBH shrinks in interactions, which can eventually lead to a gravitational wave inspiral. In this presentation I characterise the population of dynamically-assembled BBHs in a star cluster. Using direct N-body simulations, I show that, on average, a cluster only has one dynamically-assembled binary at any given time, that spends a fraction of its lifetime outside the cluster core. The presence of multiple binaries is theoretically expected, but is highly suppressed by binary-binary interactions, which are very efficient at ionising one of the binaries involved, and which also lead to the formation of triples. Finally, I will discuss the imprint of these on gravitational wave observables.

description: As multichannel equipment is increasingly used, we developed two algorithms for multivariable wavelet analysis of GPR signals (multi-cross wavelet MCW and Fourier multi-cross function FMC) and applied them to analyze raw GPR traces of archeological subsurface strata. The traces were from the tunnel located beneath the Temple of the Feathered Serpent (The Citadel, Teotihuacan, Mexico). The MCW and FMC algorithms determined the periods of subsurface strata of the tunnel. GPR traces inside-and-outside the tunnel/chamber, outside the tunnel/chamber and inside the tunnel/chamber analyzed with the MCW and filtered FMC algorithms determined the periods of the tunnel and chamber fillings, clay and matrix (limestone-clay compound). The tunnel filling period obtained by MCW analysis (14.37 ns) reflects the mixed limestone-clay compound of this stratum since its value is close to that of the period of the matrix (15.22 ns); periods of the chamber filling (11.40 ns) and the matrix (11.40 ns) were almost identical. FMC analysis of the tunnel obtained a period (5.08 ns) close to that of the chamber (4.27 ns), suggesting the tunnel and chamber are filled with similar materials. The use of both algorithms allows a deeper analysis since the similarities of the tunnel and chamber filling periods could not have been determined with the MCW algorithm alone. The successful application of the new multi-cross algorithms to archeological GPR data suggests they may also be used to search water and other resources in celestial bodies.

description: The objective of this study is to identify challenges and prospects of import customs clearance in Ethiopian Revenue & Customs Authority (ERCA). The research method used for this study is qualitative and quantitative (mixed) approach concurrently. Research data was collected from 60 ERCA customs officers and 48 importers /customs clearing agents. The sample from ERCA customs officers were selected using random sampling while importers/customs clearing agents were selected using cluster sampling technique. Open and closed-ended questionnaires and semi structured interviews were administered to the selected sample group. Both the questionnaires and the interview questions touch key characteristics of efficient and modern customs system and trade facilitation indicators. The research finding reveals that customs clearance delay is the main challenge of importers. Customs clearance delay occurs mainly at customs valuation and tariff classification work flows of the customs clearance procedures. Mistrust between the tax authority and importers/customs clearing agents, lack of human resource development, excessive requirement of commercial documents,, lack of stakeholders' consultation, continuous amendment and revision of customs regulation, and absence of single-window service, are the main causes of the prevailing customs clearance delays. Based on findings of the study, among others, the following recommendations have been forwarded: - Encourage voluntary compliance supported by post-clearance audit system, - Establishment of single-window service, - Define documents requirement clearly, - Exert all possible efforts on human resource development with the objective to create performance oriented and professional labor force. - Conduct time release study on the entire customs system of the country Key words: Challenge, Compliance, Conventions, Customs Clearance, Trade Facilitation, Single-Window Service, Post-clearance Audit, Time Release Study

description: This paper presents preliminary results from a newly excavated open-air Later Stone Age site attributed to the Wilton Industry at Kathu Pan 6 in the Northern Cape Province of South Africa. Basic data on the lithics, fauna (including a large ivory fragment), and ostrich eggshell (including beads) recovered during two seasons of excavation (2016–2017) is presented and this material is contextualized through comparison with neighboring sites. Spatial analysis of the artifact distribution from the small exposure from the 2017 season suggests a spatially structured occupation. The Wilton open-air occupation of Kathu Pan 6 offers a new perspective on the poorly understood Later Stone Age of the southern fringes of the Kalahari.
The evolution of the globular cluster mass function: The role of stellar-mass black holes
Creators: name: Gieles, Mark
Publisher: name: Zenodo

description: Stellar-mass black holes (BHs) can be retained in globular clusters (GCs) until the present. Simulations of GC evolution find that the relaxation driven mass-loss rate is elevated if BHs are present, especially near dissolution. We capture this behaviour in a parametrized mass-loss rate, bench marked by results from N-body simulations, and use it to evolve an initial GC mass function (GCMF), similar to that of young massive clusters in the Local Universe, to an age of 12 Gyr. Low-metallicity GCs ([Fe/H] ≲ -1.5) have the highest mass-loss rates, because of their relatively high BH masses, which combined with their more radial orbits and stronger tidal field in the past explains the high turnover mass of the GCMF (~10^5 Msun) at large Galactic radii (>10 kpc). The turnover mass at smaller Galactic radii is similar because of the upper mass truncation of the initial GCMF and the lower mass-loss rate due to the higher metallicities. The density profile in the Galaxy of mass lost from massive GCs (>10^5 Msun) resembles that of nitrogen-rich stars in the halo, confirming that these stars originated from GCs. We conclude that two-body relaxation is the dominant effect in shaping the GCMF from a universal initial GCMF, because including the effect of BHs reduces the need for additional disruption mechanisms.

Observing binaries in the core of NGC 6397

description: Binaries play a key role in the dynamical evolution of globular clusters. The orbital energy is a reservoir for kinetic energy of the cluster stars. To understand the physical mechanisms governing the core collapse of globular clusters, we urgently need observational constraints on the content of clusters that have already collapsed. In this respect, NGC6397 plays a pivotal role owing to its small distance and the existence of detailed model predictions. While it has previously been suggested that NGC 6397 harbors either an intermediate-mass black hole or a large number of stellar mass black holes in its center, state-of-the-art evolutionary models instead predict that NGC 6397 should host a central population of massive white dwarfs. We present first results from ongoing multi-epoch MUSE integral field spectroscopy to unveil this white-dwarf population. Based on extensive tests, we expect that observations will reveal more than 20 white dwarfs in binaries with main-sequence stars. The confrontation of the observed white dwarf binary population with model predictions will directly impact our understanding of relaxation and core collapse of massive star clusters.
Determinants of Commercial Banks off Balance Sheet Activities: an Empirical Study on Ethiopian Banking Industry

description: Off balance sheet activities have become an issue of global significance and have received attention for being a source of fee income that is beyond a bank's balance sheet activities and avoiding regulatory costs. Although much literature is available on off- balance sheet (OBS) activities in banking system, this is the first paper that investigates the off-balance sheet activities in Ethiopian banking industry. It aims to test the tax regulatory hypothesis and market discipline hypothesis in determining OBS activities of Ethiopian commercial banks using panel data set during the period of 2005-2012, with a sample of eight Ethiopian commercial banks. To answer research questions and test the hypotheses the study adopted the quantitative research approach. The model considers the impact of size, profitability, loan, credit risk, efficiency, market concentration, capital adequacy, reserve requirement, real GDP, interest rate spread and inflation on off balance sheet activities of banks. The estimation results show that all bank-specific determinants, with the exception of credit risk and loan, significantly affect commercial banks off balance sheet activities in Ethiopia. From the regulatory factors reserve requirement is also a significant determining factor of off balance sheet activities, where capital adequacy requirement negatively affects OBS activities but not significantly. Finally, with regard to macroeconomic variables, only inflation exhibits insignificant relationship with banks' OBS activities. The implications of these results suggest that regulations, institutional, and technological deficiency in Ethiopia prevent the banking system from adopting different financial innovations. The results of the study are of value to both academics and policy makers. Keywords: Off-Balance Sheets Activities, Regulatory tax hypothesis, Market discipline hypothesis and Commercial Banks
