Household Demand for Improved Sanitation Services: A Contingent Valuation Study on Addis Ababa, Ethiopia
Creators: name: Gezahegne, Biruk
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2003

description: As any developing country, lack of adequate infrastructure provision is an enormous problem in Ethiopia. When we see the case of Addis Ababa, the current coverage of sanitation service is very low. It is this very fact that has made the government of Ethiopia to extend a concerted effort to improve the condition. In doing so, the government has stated that, the policy for increasing the coverage as well as the proper use of any sustainability of the service requires implementation of a cost recovery system. But this requires information on people's preferences and WTP for the proposed improvement. Therefore, the paper examined the determinants of willingness-to-pay for improved sanitation service and investigates the possibility of cost recovery policy directions using the contingent valuation method. For the three suggested improvements (WTP for sewer connection, WTP for improved sludge disposal and WTP for public toilets) a face-to-face personal interview using bidding game elicitation technique on 440 households was conducted. The Heckman two-step estimator used for the empirical analysis revealed that income, education, family size and age are factors, which consistently affect the decisions whether or not one is willing to pay and the willingness to pay amount for the three WTP scenarios. In matching demand and supply, for the two suggested improvements (WTP for sewer system and WTP for improved sludge disposal), the mean WTP showed that consumers are not able to pay for the improvement to attain full recovery basis. The paper has shown the need for integrated design criteria for the respective sanitation facilities to achieve improvement in the service. Key Words: Willingness-to-pay, improved sanitation service, Heckman two-step estimator, contingent valuation method, Addis Ababa, Ethiopia

description: Ultraviolet completion of the standard model plus gravity at and beyond the Planck scale is a daunting problem to which no generally accepted solution exists. Principal obstacles include (a) lack of data at the Planck scale (b) nonrenormalizability of gravity and (c) unitarity problem. Here we make a simple observation that, if one treats all Planck scale operators of equal canonical dimension democratically, one can tame some of the undesirable features of these models. With a reasonable amount of fine tuning one can satisfy slow roll conditions required in viable inflationary models. That remains true even when the number of such operators becomes very large.

description: This paper deals with the identification of piecewise affine state-space models. These models are obtained by partitioning the state or input domain into a finite number of regions and by considering affine submodels in each region. The proposed framework uses the Expectation Maximization (EM) algorithm to identify the parameters of the model. In most of the current literature, a discrete random variable with a discrete transition density is introduced to describe the transition between each submodel, leading to a further approximation of the dynamical system by a jump Markov model. On the contrary, we use the cumulative distribution function (CDF) to compute the probability of each submodel given the measurement at that time step. Then, given the submodel at each time step the latent state is estimated using the Kalman smoother. Subsequently, the parameters are estimated by maximizing a surrogate function for the likelihood. The performance of the proposed method is illustrated using the simulated model of the JAS 39 Gripen aircraft.

Year: 2002

description: This study uses a simultaneous equation approach to investigate the impact of external debt on economic growth in Ethiopia using a macroeconometric model estimated for 1970-2000. The empirical findings reveal that external debt does not affect growth directly. The results indicate that external debt affects investment positively and is statistically significantly indicating external debt in Ethiopian case encourage investment rather than depress it. Furthermore, the result also confirms that there is no sign of crowding out effect through which external debt is hypothesized to affect growth.

description: We study possible string theory compactifications which, in the low-energy limit, describe chaotic inflation with a stabilizer field. We first analyze type IIA setups where the inflationary potential arises from a D6-brane wrapping an internal three-cycle, and where the stabilizer field is either an open-string or bulk Kähler modulus. We find that after integrating out the relevant closed-string moduli consistently, tachyonic directions arise during inflation which cannot be lifted. This is ultimately due to the shift symmetries of the type IIA Kähler potential at large compactification volume. This motivates us to search for stabilizer candidates in the complex structure sector of type IIB orientifolds, since these fields couple to D7-brane Wilson lines and their shift symmetries are generically broken away from the large complex structure limit. However, we find that in these setups the challenge is to obtain the necessary hierarchy between the inflationary and Kaluza-Klein scales.

Analysis of market power and competitiveness of Ethiopian insurance industry
Creators: name: Beyene, Shimelis
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: Competition in the economy can create a positive prospect for economic growth and development of a country. Competition in Ethiopian financial sector in general and insurance industry in particular should be strong enough for enhancement of efficiency, provision of better service to customers, greater innovation and lower prices thus resulting in improvement of consumers welfare and overall economic growth of the country. Since the introduction of modern financial sector in Ethiopia in 1905, the market structure of insurance industry in Ethiopia is characterized by competition and monopoly depending on the financial policies issued by the ruling governments of the country. This paper studies the existence of market power in the Ethiopian insurance industry during 2001- 2010, using non-structural measures of market power such as market share and Lerner index. And hence insurance market concentration is measured by using Herfindahl-Hirschman Index (HHI) and four largest insurers' concentration ratio (CR). These measures suggest the existence of market power in insurance industry of Ethiopia and the sector was dominated by the single state owned Ethiopian Insurance Corporation (EIC). The major source of dominance tends towards government regulation that is prohibition of foreign investors in financial sector of the country in general and insurance sector in particular. The study also reveals that Ethiopian insurance market is highly concentrated and the top four insurers holds above 70% of the market share in terms of gross premium, total asset and capital. Key words: market power, market concentration, market dominance, entry barrier.

description: We present a preliminary design for a novel neutron detection system that is compact, lightweight, and low power consuming, utilizing the CubeSat platform making it suitable for space-based applications. This is made possible using the scintillating crystal lithium indium diselenide ($^6$LiInSe$_2$), the first crystal to include $^6$Li in the crystalline structure, and a silicon avalanche photodiode (Si-APD). The schematics of this instrument are presented as well as the response of the instrument to initial testing under alpha radiation. A principal aim of this work is to demonstrate the feasibility of such a neutron detection system within a CubeSat platform. The entire end-to-end system presented here is 10 cm x 10 cm x 15 cm, weighs 670 grams and requires 5 Volts direct current at 3 Watts.

description: In the light of the recent result from KamLAND-Zen (KLZ) and GERDA Phase-II, we update the bounds on the effective mass and the new physics parameters, relevant for neutrinoless double beta decay ($0νββ$). In addition to the light Majorana neutrino exchange, we analyze beyond standard model contributions that arise in Left-Right symmetry and R-Parity violating supersymmetry. The improved limit from KLZ constrains the effective mass of light neutrino exchange down to sub-eV mass regime 0.06 eV. Using the correlation between the $^{136}\rm{Xe}$ and $^{76}\rm{Ge}$ half-lives, we show that the KLZ limit individually rules out the positive claim of observation of $0νββ$ for all nuclear matrix element compilation. For the Left-Right symmetry and R-parity violating supersymmetry, the KLZ bound implies a factor of 2 improvement of the effective mass and the new physics parameters. The future ton scale experiments such as, nEXO will further constrain these models, in particular, will rule out standard as well as Type-II dominating LRSM inverted hierarchy scenario.

description: Integration-by-parts reductions play a central role in perturbative QFT calculations. They allow the set of Feynman integrals contributing to a given observable to be reduced to a small set of basis integrals, and they moreover facilitate the computation of those basis integrals. We introduce an efficient new method for generating integration-by-parts reductions. This method simplifies the task by making use of generalized-unitarity cuts and turns the problem of finding the needed total derivatives into one of solving certain polynomial (so-called syzygy) equations.

Analysis of Factors Affecting the Technical Efficiency of Coffee Producers in Jimma Zone: A Stochastic Frontier Analysis
Creators: name: Ethiopia, Alemayehu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: Ethiopian coffee production and its productivity level are unsatisfactory to uphold the country's comparative advantage. The study intends to examine possible reasons for low productive performance of coffee using cross sectional data gathered from Jimma zone. An attempt to measure technical efficiency of coffee producers, analysis of its determinants and the impact of various distributional assumptions on technical efficiency estimates is made. Accordingly, both error component model and technical inefficiency effects model have been estimated in one step approach after data have been transformed. Maximum likelihood estimate of technical efficiency was obtained from truncated normal model which was supposed to describe the data adequately. The result revealed that various distributional assumptions of technical inefficiency have approximately similar impact of on TE estimates. On average, coffee producers are 72% efficient, implying that there is ample opportunity for these farmers to raise output level at present technology. There is also advantage of scale economies linked to increasing returns to boost output. Except fertilizer, overutilization of other inputs leads to inefficiency. Technical inefficiency effects are modeled as a function of farmer specific socio-economic factors. Education, distance, family pressure and poor soil fertility tends to increase technical inefficiency of farmers whereas off farm income, proximity to market, cereal crop production, sex and good soil fertility improves their technical efficiency. Farmers can still produce higher output under available technology, indeed. Therefore, government should target at development of rural infrastructure, work diversification, rural employment creation, promotion of rural female management through awareness creation and soil conservation to overturn output loss by technical inefficiency of coffee producers in Jimma zone

By performing Wilsonian renormalization group analysis of the low-energy effective field theory of the minimal model with triple-Weyl nodes, we find that the fixed point of noninteracting triple-Weyl fermions is unstable in the presence of Coulomb interactions and flows to a nontrivial stable fixed point representing marginal Fermi liquids with anisotropic screening effects. We further discuss relevant unusual physical consequences due to the novel behavior of correlation effects in this system.

description: A trophallaxis inspired model for distributed transport between randomly interacting agents Trophallaxis, the regurgitation and mouth to mouth transfer of liquid food between members of eusocial insect societies, is an important process that allows the fast and efficient dissemination of food in the colony. Trophallactic systems are typically treated as a network of agent interactions. This approach, though valuable, does not easily lend itself to analytic predictions. In this work we consider a simple trophallactic system of randomly interacting agents with finite carrying capacity, and calculate analytically and via a series of simulations the global food intake rate for the whole colony as well as observables describing how uniformly the food is distributed within the nest. Our work serves as a stepping stone to describing the collective properties of more complex trophallactic systems, such as those including division of labor between foragers and workers.

The Impact of Foreign Aid on Public Spending the Case of Ethiopia
Creators: name: Tarekegn, Jifar
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2002

description: This paper seeks to address the effect of foreign aid on public spending with particular reference to the case of aid fungibility in Ethiopia. In this paper, 4 developmental sector and 3 non-developmental sector were considered. Agriculture, construction, education and transport& communication were classified as developmental expenditure while, defense, general service and debt servicing were classified as non-developmental expenditure. For each developmental sector, GDP, sector specific aid and aid other than the sector specific aid variables are considered for explanatory variables and sector specific spending is considered as dependent variables. The analysis was done using OLS estimation. In estimating the long run model, first, the time series characteristic of the data is tested using ADF test and found that all the variables in developmental and non-developmental models are integrated order of one. Then, the cointegration test was conducted and concluded that there is one cointegrating vector between developmental spending, sector-specific aid, other aid and GDP. It is also found that there is one cointegrating vector b/n non-developmental spending, foreign aid and GDP. The test of weak exogenity indicate that all explanatory variables in developmental model are weakly exogenous. Before going to estimation, the following step is to test zero restriction on the coefficients of explanatory variables in which case, at least one of the explanatory variable coefficient is found to be significantly different from zero. In estimating the short run impact, ECM method was employed after knowing not only that there is one cointegrating vector between dependent and explanatory variables, but also the variables are integrated of order one I(1). Hence, the estimated result in education and agriculture sectors were marked by non-fungiblity in which case the sectoral aid impact on sectoral spending have crowding in effect. However, for transport & communication and construction sector, aid fungiblity seems to exist which means that there is crowding out effect. In this case, the sectoral aid impact on the sectors spending is negative. For non developmental expenditure, aid is found to be significantly affecting debt servicing expenditure but insignificant for general service and defense expenditures.

description: Collective coupling between dipoles can dramatically modify the optical response of a medium. Such effects depend strongly on the geometry of the medium and the polarization of the light. Using a classical coupled dipole model, here we investigate the simplest case of one dimensional (1D) arrays of interacting atomic dipoles driven by a weak laser field. Changing the polarization and direction of the driving field allows us to separately address superradiant, subradiant, red-shifted, and blue-shifted eigenmodes, as well as observe strong Fano-like interferences between different modes. The cooperative eigenvectors can be characterized by the phase difference between nearest neighbor dipoles, ranging from all oscillating in phase to all oscillating out of phase with their nearest neighbors. Investigating the eigenvalue behavior as a function of atom number and lattice spacing, we find that certain eigenmodes of an infinite atomic chain have the same decay rate as a single atom between two mirrors. The effects we observe provide a framework for collective control of the optical response of a medium, giving insight into the behavior of more complicated geometries, as well as providing further evidence for the dipolar analog of cavity QED.

description: The use of artificial intelligence (AI), represented by artificial neural networks (ANN), is one of the most recent approaches of modeling in the field of research and development. In this study, 5 artificial neural networks were developed to estimate the major parameters of the catalytic process of steam reforming of methane in fluidized catalytic bed reactors using nickel-based catalyst, based on operational and design factors. Recently, research interest in artificial neural networks has expanded because to its capacity to differentiate applications efficiently solve complicated difficulties, reliability, and low cost when compared to other complex modeling and simulation approaches. It is stated that ANN is a useful performance evaluation tool for chemical engineering researchers in forecasting operational and design parameters for both academic and practical applications.

description: Capillary interactions can be used to direct assembly of particles adsorbed at fluid-fluid interfaces. Precisely controlling the magnitude and direction of capillary interactions to assemble particles into favoured structures for materials science purposes is desirable but challenging. In this paper, we investigate capillary interactions between magnetic Janus particles adsorbed at fluid-fluid interfaces. We develop a pair-interaction model that predicts that these particles should arrange into a side--side configuration, and carry out simulations that confirm the predictions of our model. Finally, we investigate the monolayer structures that form when many magnetic Janus particles adsorb at the interface. We find that the particles arrange into long, straight chains exhibiting little curvature, in contrast with capillary interactions between ellipsoidal particles. We further find a regime in which highly ordered, lattice-like monolayer structures form, which can be tuned dynamically using an external magnetic field.

description: Dirac-like electronic states are the main engines powering the tremendous advances in research of graphene, topological insulators and other materials with these states. Zero effective mass, high carrier mobility and numerous applications are some consequences of linear dispersion that distinguishes Dirac states. Here we report a new class of linear electronic bands in two-dimensional materials with zero effective mass and sharp band edges never seen in solid state matter before, and predict stable materials with such electronic structure utilizing symmetry group analysis and ab initio approach. We make a full classification of completely linear bands in two-dimensional materials and find that only two classes exist: Dirac fermions on one hand and pyramidal-like and cootie catcher-like states on the other hand. The new class supports zero effective mass and hence high carrier mobility similar to that of graphene, anisotropic electronic properties like that of phosphorene, and robustness of states with respect to electronic correlations.
The Determinants of Foreign Direct Investment in Ethiopia: A Co-Integrated VAR Approach
Creators: name: Temeselew, Liya
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Developing countries around the world are competing to attract FDI in hope of its contribution to economic development. This increasing competition gives rise to interest in the performance of Ethiopia regarding FDI inflows, the measures being taken to increase these inflows as well as the current issues that deter the inflow. This paper gives an analysis of Foreign Direct Investment in Ethiopia by first observing the different policy reforms and by analyzing the sectorial and regional distribution of FDI as well as by looking at the different opportunities and challenges faced by foreigners interested in investing in the country. In addition, in this study different factors that determine the inflow of FDI to the country are analyzed. The study uses secondary data form1980-2014 collected from various national and international sources. The results show that FDI in Ethiopia is significantly and positively affected by human capital, exchange rate, domestic investment and GDP. In addition it is shown that while exports have a positive and significant impact on FDI, and FDI has a positive impact on export as well. With these findings the study recommends that the government should concentrate on stimulating the above macroeconomic variables and creating a hospitable environment for investment so as to increase the inflow FDI and fuel the Ethiopian economy.

description: Solar electron beams responsible for type III radio emission generate Langmuir waves as they propagate out from the Sun. The Langmuir waves are observed via in-situ electric field measurements. These Langmuir waves are not smoothly distributed but occur in discrete clumps, commonly attributed to the turbulent nature of the solar wind electron density. Exactly how the density turbulence modulates the Langmuir wave electric fields is understood only qualitatively. Using weak turbulence simulations, we investigate how solar wind density turbulence changes the probability distribution functions, mean value and variance of the beam-driven electric field distributions. Simulations show rather complicated forms of the distribution that are dependent upon how the electric fields are sampled. Generally the higher magnitude of density fluctuations reduce the mean and increase the variance of the distribution in a consistent manor to the predictions from resonance broadening by density fluctuations. We also demonstrate how the properties of the electric field distribution should vary radially from the Sun to the Earth and provide a numerical prediction for the in-situ measurements of the upcoming Solar Orbiter and Solar Probe Plus spacecraft.

description: This study aimed at examining whether Common Market for Eastern and Southern Africa (COMESA) is effective in promoting trade among its member states. The study uses gravity model to estimate the trade intensity among its members for the year 1981 and 1999. The gravity model is applied to trade intensity indices and the estimation of the gravity equation is carried out using Tobit regression. The empirical results indicate that the standard gravity model variables have the expected effect on the trade linkage in COMESA. The main focus of the study is, on the estimation of COMESA, which is found to be insignificant in promoting trade among members. A comparison of the two periods result reveals a very similar pattern before and after the formation of COMESA. Thus, the result confirms the ineffectiveness of COMESA in enlarging trade among its members. Accordingly, the study suggests the requirement of joint effort of the member countries in coordinating, harmonizing and implementing policies, improving their human and institutional capabilities, increasing production capacity and expanding markets by involving active participation of the private sector so as to raise intra-COMESA trade.

description: Quasar-driven outflows naturally account for the missing component of the extragalactic $γ$-ray background through neutral pion production in interactions between protons accelerated by the forward outflow shock and interstellar protons. We study the simultaneous neutrino emission by the same protons. We adopt outflow parameters that best fit the extragalactic $γ$-ray background data and derive a cumulative neutrino background of $\sim10^{-7}\,\rm GeV\,cm^{-2}\,s^{-1}\,sr^{-1}$ at neutrino energies $E_ν\gtrsim 10$ TeV, which naturally explains the most recent IceCube data without tuning any free parameters. The link between the $γ$-ray and neutrino emission from quasar outflows can be used to constrain the high-energy physics of strong shocks at cosmological distances.

description: Decoupling of total electronic and nuclear spin moments of Cs atoms in external magnetic field for the case of atomic $D_1$ line, leading to onset of the hyperfine Paschen-Back regime has been studied theoretically and experimentally. Selective reflection of laser radiation from an interface of dielectric window and atomic vapor confined in a nanocell with 300 nm gap thickness was implemented for the experimental studies. The real time derivative of selective reflection signal with a frequency position coinciding with atomic transitions was used in measurements, providing $\sim$ 40 MHz spectral resolution and linearity of signal response in respect to transition probability. Behavior of 28 individual Zeeman transitions in a wide range of longitudinal magnetic field (0 - 6 kG) has been tracked under excitation of Cs vapor by a low-intensity $σ^+$- polarized cw laser radiation. For $B\ge 6~$kG, only 8 transitions with nearly equal probabilities and the same frequency slope remained in the spectrum, which is a manifestation of the hyperfine Paschen-Back regime. The obtained experimental results are consistent with numerical modeling. Due to small divergence of selective reflection signal, as well as sub-wavelength thickness and sub-Doppler spectral linewidth inherent to nanocell, the employed technique can be used for distant remote sensing of magnetic field with high spatial and $B$-field resolution.

description: In compositional model-theoretic semantics, researchers assemble truth-conditions or other kinds of denotations using the lambda calculus. It was previously observed that the lambda terms and/or the denotations studied tend to follow the same pattern: they are instances of a monad. In this paper, we present an extension of the simply-typed lambda calculus that exploits this uniformity using the recently discovered technique of effect handlers. We prove that our calculus exhibits some of the key formal properties of the lambda calculus and we use it to construct a modular semantics for a small fragment that involves multiple distinct semantic phenomena.

description: Kiwi extract (KE) including different components such as quercetin, vitamins C and E, and actinides has been known as a debridement agent for burn wounds. In this study, electrospun poly(ɛ-caprolactone)/cellulose acetate blend nanofibers incorporating KE (PCL/CA/KE) were prepared and their performance was evaluated for healing acceleration of burn wounds. The physicochemical characterization of PCL/CA/KE nanofibers showed an average diameter of ∼420 nm, porosity of 70%, water contact angle of 61°, and water uptake of ∼220%. Moreover, the continuous release trend of KE from PCL/CA blend nanofibers happened during 24 h and the release mechanism was governed by the Fickian diffusion. Besides the cytocompatibility of PCL/CA/KE nanofibers, their in vivo experiments revealed that the bioactive wound dressing based on the sample has higher wound closure compared to KE after 21 days. Histopathology of wounds dressed by PCL/CA/KE nanofibers indicated epidermal formation along with a fully extended layer. Eventually, the obtained results confirmed that the PCL/CA/KE nanofibrous sample was a promising wound dressing for burn wound healing.

description: High-harmonic generation (HHG) in condensed-matter systems is both a source of fundamental insight into quantum electron motion and a promising candidate to realize compact ultraviolet and ultrafast light sources. Here we argue that the large light intensity required for this phenomenon to occur can be reached by exploiting localized plasmons in conducting nanostructures. In particular, we demonstrate that doped graphene nanostructures combine a strong plasmonic near-field enhancement and a pronounced intrinsic nonlinearity that result in efficient broadband HHG within a single material platform. We extract this conclusion from time-domain simulations using two complementary nonperturbative approaches based on atomistic one-electron density-matrix and massless Dirac-fermion Bloch-equation pictures. High harmonics are predicted to be emitted with unprecedentedly large intensity by tuning the incident light to the localized plasmons of ribbons and finite islands. In contrast to atomic systems, we observe no cutoff in harmonic order. Our results support the strong potential of nanostructured graphene as a robust, electrically tunable platform for HHG.

description: Introducing up-down asymmetry into the tokamak magnetic equilibria appears to be a feasible method to drive fast intrinsic toroidal rotation in future large devices. In this paper we investigate how the intrinsic momentum transport generated by up-down asymmetric shaping scales with the mode number of the shaping effects. Making use the gyrokinetic tilting symmetry (Ball et al (2016) Plasma Phys. Control. Fusion 58 045023), we study the effect of envelopes created by the beating of different high-order shaping effects. This reveals that the presence of an envelope can change the scaling of the momentum flux from exponentially small in the limit of large shaping mode number to just polynomially small. This enhancement of the momentum transport requires the envelope to be both up-down asymmetric and have a spatial scale on the order of the minor radius.
