description: Following the induced gravitational collapse (IGC) paradigm of gamma-ray bursts (GRBs) associated with type Ib/c supernovae, we present numerical simulations of the explosion of a carbon-oxygen (CO) core in a binary system with a neutron-star (NS) companion. The supernova ejecta trigger a \emph{hypercritical} accretion process onto the NS thanks to a copious neutrino emission and the trapping of photons within the accretion flow. We show that temperatures 1--10~MeV develop near the NS surface, hence electron-positron annihilation into neutrinos becomes the main cooling channel leading to accretion rates $10^{-9}$--$10^{-1}~M_\odot$~s$^{-1}$ and neutrino luminosities $10^{43}$--$10^{52}$~erg~s$^{-1}$ (the shorter the orbital period the higher the accretion rate). We estimate the maximum orbital period, $P_{\rm max}$, as a function of the NS initial mass, up to which the NS companion can reach by hypercritical accretion the critical mass for gravitational collapse leading to black-hole (BH) formation. We then estimate the effects of the accreting and orbiting NS companion onto a novel geometry of the supernova ejecta density profile. We present the results of a $1.4\times 10^7$~particle simulation which show that the NS induces accentuated asymmetries in the ejecta density around the orbital plane. We elaborate on the observables associated with the above features of the IGC process. We apply this framework to specific GRBs: we find that X-ray flashes (XRFs) and binary-driven hypernovae (BdHNe) are produced in binaries with $P>P_{\rm max}$ and $P < P_{\rm max}$, respectively. We analyze in detail the case of XRF 060218.

The Impact of Employee Turnover on Sustainable Development Activities: the Case of Bole Sub City, Addis Ababa
Creators: name: Seifu, Meron
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The main purpose of the study was to investigate the impact of Employee turnover on sustainable development activities in Bole Sub City, Addis Ababa. It focused on challenges and prospects of the employees services for sustainable development activities with the aim to suggest alternative solutions to the identified problems. The research methodology employed in this study was descriptive survey. Accordingly, survey questionnaire was prepared, pilot tested and administered to a sample of 118 respondents composed of 103 current employees' respondents and 10 former employees' respondents. A total of 113 (95.76%) questionnaires were properly completed and returned. In addition, interview, observation and document analysis were made to collect the necessary information. From twenty seven core process owner or offices and human resource core process owner or office were selected using simple random sampling techniques. Non probability sampling technique was employed to select current employee respondents whereas purposive sampling technique was employed to select former employee respondents. Results obtained were analyzed by using descriptive method such as frequency counts, percentage and narrative description. The result of the study indicated the following. The employee turnover that Bole sub city face are increase rapidly, majority of current employees (92.4%) believed and responded as, when their level of qualification increases their chance of working in the organization decreases. The sustainable development activities are exclusively designed to address economic, political, cultural and ecological sustainability. The major factors affecting the performance of sustainable development activities were found to be lack of professional employees or Employee turnover, unproportionality of the number of employees with sustainable development activities. Thus, to alleviate the above problems the following recommendations were forwarded. The concerned bodies should pay due emphasis to strengthen the current employees situation that the sub city is rendering. The sub city should consider qualification and experience in promoting employees; the organization should continue and improve this good practice. Finally, the Addis Ababa city Administration should reconsider the current economic situation of employees to encourage tenure and quality of Employee to support the sustainable development activities
Measuring Consumer-Based Brand Equity In The Beverage Sector: The Case Of Tomoca Coffee

description: Consumer based brand equity plays a vital role in contemporary marketing. Firms with high brand equity have the privilege of having higher consumer preferences, high stock returns, greater loyalty, less vulnerability to competitive marketing actions, less vulnerability to marketing crises and larger margins This research study aimed to explore the most influential factors that are behind the brand equity of Tomoca coffee. The most common and widely used conceptual framework of Aaker was used. The model consists of five dimensions of brand equity namely perceived quality, brand awareness, brand association and brand loyalty. These dimensions represent customers' evaluations and reactions to the brand that can be readily understood by consumers and hence they have been widely adapted to measure customer-based brand equity. A quantitative research design was applied to research the causal relationship of the brand equity measurement dimensions to that of overall brand equity. A systematic sampling technique was conducted to contact the sample respondents who are the customers of Tomoca coffee. Applying a structured questionnaire written both in Amharic and English the researcher distributed to 422 people personally. Out of the total questionnaires distributed, 386 were considered valid for analysis. The analysis was performed using frequency, mean, standard deviation, correlation and regression by means of SPSS software. Then the collected data were analyzed and interpreted. The findings show that all the dimensions of CBBE have a positive significant influence on brand equity.

description: Human perceptions of tap water provide valuable insights for decision-making in resource-constrained rural water systems. This study evaluated differences in tap water sentiments across households within a single water utility, focusing on safety, satisfaction, and overall ratings. Predictors considered included socioeconomic demographics, water issues, consumption patterns, boil water advisories, and variables derived from individual cognitive maps (networks of perceived causal relationships among factors structuring a coupled human-natural system). The primary objective was to create a data-driven decision-making tool that connects human perceptions, cognitive maps, and water quality to inform a potential complementary method to costly water testing to determine areas of water distribution systems that may require targeted action to improve water quality. Surveys and cognitive map data were collected from 24 households along with tap water quality measurements to elucidate connections between coupled human and natural systems. Multiple linear regression and correlation analyses were used to evaluate interactions between tap water quality, customer perceptions, and the broader environment. Findings revealed that water issues significantly influence water perceptions. Positive sentiments generally aligned with measured water quality levels did not exceed regulated and recommended levels. Study findings show that narratives provided by water utility customers enriched understanding of rural water utilities in Appalachian Ohio. This framework underscores the feasibility and significance of integrating diverse datasets for predicting tap water outcomes to inform decisions for enhancing tap water quality and water system service.

description: By means of hybrid multi-particle collsion--particle-in-cell (MPC-PIC) simulations we study the dynamical scaling of energy and density correlations at equilibrium in moderately coupled 2D and quasi 1D plasmas. We find that the predictions of Nonlinear Fluctuating Hydrodynamics for the structure factors of density and energy fluctuations in 1D systems with three global conservation laws hold true also for two dimensional systems that are more extended along one of the two spatial dimensions. Moreover, from the analysis of the equilibrium energy correlators and density structure factors of both 1D and 2D neutral plasmas, we find that neglecting the contribution of the fluctuations of the vanishing self-consistent electrostatic fields overestimates the interval of frequencies over which the anomalous transport is observed. Such violations of the expected scaling in the currents correlation are found in different regimes, hindering the observation of the asymptotic scaling predicted by the theory.

Year: 2017

description: Brand Loyalty is one of the major tools for any company to survive in a severe competition. Brand helps in creating relationship between consumer and producer. The purpose of this study was to investigate the influence of perceived value, service quality, customer satisfaction on brand loyalty of customers in a comparative study between Commercial bank of Ethiopia and Awash International bank. Perceived value, service quality and customer satisfaction were determined to be the input and intervening variables and brand loyalty was determined to be the output variable and based on this a structured questionnaire was developed. The five hypotheses were simultaneously tested on a sample of 344 customers out of 384 distributed, giving a valid response rate of 90 percent. The finding of this study shows that all of the three variables have positive and significant relationship with brand loyalty which led to the acceptance of the four hypotheses. The testing of the fifth and the final hypothesis, which set out to find any significant difference with regard to perceived value, service quality, customer satisfaction and brand loyalty between Commercial and Awash international bank; there is no significant difference in the means of service quality and brand loyalty, however there is significant difference between the means of perceived value and customer satisfaction between the two banks. This led to the partial acceptance of the fifth hypothesis. These findings are beneficial for both banks to gain brand loyal customers.

description: La Société française d’hygiène hospitalière (SF2H) a édité en 2019 un guide de recommandations Prévention du risque infectieux associé aux actes d’échographie endocavitaire. En 2022, le CPias Grand-Est a proposé, avec l’aide des autres CPias, une enquête inter-régionale auprès des équipes opérationnelles d’hygiène pour évaluer l’intégration de ces nouvelles mesures dans les protocoles des établissements de santé. Il s’agissait d’un audit documentaire déclaratif pour évaluer les procédures. L’enquête s’est déroulée du 2 janvier au 30 juin 2022. En pratique, 240 établissements de 17 des 18 régions françaises y ont participé. L’appropriation des recommandations de la SF2H pour améliorer la sécurité des soins est médiocre sur cet échantillon. La durée d’usage de gel d’échographie en flacon multidose dépasse la journée de travail et ne fait pas l’objet de traçabilité sur le jour et l’heure d’ouverture. Les procédures ne sont pas organisées 24 h/24 pour 15% des répondants. Les procédures de nettoyage et de désinfection des sondes par lingettes méritent d’être précisées quant à la nature des lingettes utilisées pour les étapes de détersion puis de désinfection. Des confusions relevées dans le déclaratif laissent penser que la désinfection n’est pas toujours réalisée. Le séchage de la sonde nettoyée et désinfectée par lingettes n’apparaît pas dans 20% des procédures. Le bionettoyage de l’environnement entre deux examens et la désinfection complète du poste de nettoyage en fin de journée ne sont pas toujours indiqués. L’information des patients sur le risque infectieux n’est prévue que dans moins d’un quart des procédures. De nombreux points restent donc à améliorer et devront faire l’objet d’une nouvelle évaluation en 2023. Un rappel des recommandations SF2H aux utilisateurs dans les établissements devrait aussi être proposé.

Year: 2016

description: A smooth function of the second moments of $N$ continuous variables gives rise to an uncertainty relation if it is bounded from below. We present a method to systematically derive such bounds by generalizing an approach applied previously to a single continuous variable. New uncertainty relations are obtained for multi-partite systems which allow one to distinguish entangled from separable states. We also investigate the geometry of the "uncertainty region" in the $N(2N+1)$-dimensional space of moments. It is shown to be a convex set for any number continuous variables, and the points on its boundary found to be in one-to-one correspondence with pure Gaussian states of minimal uncertainty. For a single degree of freedom, the boundary can be visualized as one sheet of a "Lorentz-invariant" hyperboloid in the three-dimensional pace of second moments.

description: The problem of constructing optimal designs for a class of regression models is considered. We investigate a version of the Tp-optimality criterion as introduced by Atkinson and Fedorov (1975b) and demonstrate that optimal designs with respect to this type of criteria can be obtained by solving (nonlinear) vector-valued approximation problems. We provide a characterization of the best approximations in this context and use these results to develop an efficient algorithm for the determination of the optimal discriminating designs. The results are illustrated by fnumerical examples.

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

description: This study was conducted to assess factors affecting quality service delivery in the case of Addis Ababa Bole International Airport. Descriptive method of research was adopted in carrying out this study. The primary sources were passengers of Addis Ababa Bole International Airport, who are the end users of airport facilities and services and the senior management and employees of front line area service provides from different sectors. A sample of 400 service users (passengers) and 280 front line service providers of the indicated airport were selected .The sampling techniques employed in this research were non probability sampling method, which is, convenience sampling for passenger (end users) respondents and in order to get more accurate representation from each heterogeneous subgroup of service providers in an organization under study stratified random sampling was undertaken so as to change in to homogeneous groups. Then simple random sampling technique was selected from their list by their strata like airport, airline, custom, immigration security and others. Data were collected using structured questionnaire and analyzed by SPSS windows version 23.0.The questions were measured on a five-point Likert scale, with being strongly agree, agree, neutral, disagree and strongly disagree rating scales. Passengers were asked to rate airport services and facilities like: airport access, airport services and facilities, airport restaurants, airport shopping facilities, airport service personnel and security, airport environment, airport immigration and customs while front line service providers were asked to rate their organizational policy and suitability of their working environment. Major challenges found from passengers and first line service providers in the study indicate that: non clarity of airport terminal signs and symbols to find ways easily, inconvenience of flight information display to get adequate information, queue length at every check- points, inadequate banking service or money changers, un clean rest rooms, less accessibility to internet/ Wi-Fi services, expensive prices in restaurants and shops , lack of trainings that increase efficiency of employees, unfair selections for trainings, in adequate office arrangements and work equipment suitable for work were the most common problems contributed to affect the quality of service delivery in the study area.

description: The problem of finding a maximum-size matching in a graph appears in many situations in graph theory. Therefore it is crucial to compute such matchings in a fast way. In some cases a hybrid algorithm, consisting of an heuristic to find a start-matching and an exact algorithm to compute the maximum-size matching, appears to be much faster than classical algorithms. We show a way to implement appropriate heuristics, exact algorithms and hybrid algorithms in C++ and compare their performance on different random graphs. To reduce the programming-effort , we used comprehensible techniques. These techniques can be implemented indepen- dent of programming languages and the operating systems.

description: We calculate exactly the time-dependent reduced density matrix for the central spin in the central-spin model with homogeneous Heisenberg couplings. Therefrom, the dynamics and the entanglement entropy of the central spin are obtained. A rich variety of behaviours are found, depending on the initial state of the bath spins. For an initially unpolarized unentangled bath, the polarization of the central spin decays to zero in the thermodynamic limit, while its entanglement entropy becomes maximal. On the other hand, if the unpolarized environment is initially in an eigenstate of the total bath spin, the central spin and the entanglement entropy exhibit persistent monochromatic large-amplitude oscillations. This raises the question of to what extent entanglement of the bath spins prevents decoherence of the central spin.

description: Strong gravitational lens systems with time delays between the multiple images allow measurements of time-delay distances, which are primarily sensitive to the Hubble constant that is key to probing dark energy, neutrino physics, and the spatial curvature of the Universe, as well as discovering new physics. We present H0LiCOW ($H_0$ Lenses in COSMOGRAIL's Wellspring), a program that aims to measure $H_0$ with $<3.5\%$ uncertainty from five lens systems (B1608+656, RXJ1131-1231, HE0435-1223, WFI2033-4723 and HE1104-1805). We have been acquiring (1) time delays through COSMOGRAIL and Very Large Array monitoring, (2) high-resolution Hubble Space Telescope imaging for the lens mass modeling, (3) wide-field imaging and spectroscopy to characterize the lens environment, and (4) moderate-resolution spectroscopy to obtain the stellar velocity dispersion of the lenses for mass modeling. In cosmological models with one-parameter extension to flat $Λ$CDM, we expect to measure $H_0$ to $<3.5\%$ in most models, spatial curvature $Ω_{\rm k}$ to 0.004, $w$ to 0.14, and the effective number of neutrino species to 0.2 (1$σ$ uncertainties) when combined with current CMB experiments. These are, respectively, a factor of $\sim15$, $\sim2$, and $\sim1.5$ tighter than CMB alone. Our data set will further enable us to study the stellar initial mass function of the lens galaxies, and the co-evolution of supermassive black holes and their host galaxies. This program will provide a foundation for extracting cosmological distances from the hundreds of time-delay lenses that are expected to be discovered in current and future surveys.

Assessment on Employees' Attitude Towards the Implementation of Private Pension Scheme:the Case of Save the Children International
Creators: name: Abebe, Netsanet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The primary objective of this study is to assess the attitudes of employees, at Save the Children, on the implementation of the recently introduced private pension scheme. In this sense, self- administered structured questionnaire was used to collect quantitative data while in depth interview was used for the qualitative study. Simple random sampling was used to select respondents from the total population of Save the Children Addis Ababa/International –based staff members who were previously part of provident fund scheme. The researcher has followed the approach of descriptive qualitative research method and applied simple random sampling technique. The data have been collected using structured, semi-structured questionnaires and interviews, as well as reading materials of the target area. The finding from the descriptive analysis revealed that employees of Save the Children International were well aware of the pros and cons of both the pension and provident fund schemes. The second finding disclosed that the majority of the employees prefer the provident fund over the pension scheme. The analysis also indicated employees' dissatisfaction with the implementation of the private pension scheme and the consequent several different factors were attached with the dissatisfaction. The findings, therefore, suggested the need for government to further improve the implementation modality of Private Employees' Pension Proclamation No. 715/2011 in such a way it protects the safety of all citizens. Among such complementary measures is the provision of preretirement withdrawals/loans to those NGO employees with less than 10 years of experience and who would be forced to leave a certain job and wait for the other to come as the lifetimes of jobs in the NGO sector are naturally contract-based and obviously are regulated by the phasing-in and phasing-out projects. The measures, therefore, must protect the interests of the services and tributes of this section of the society from this danger of ending-up with being nothing for their later times; and, in this sense, the measures must benefit these employees to be able to get their genuine tributes and possibly invest for other sources of income that would ensure their living during their retirement ages. Key words: Pension Scheme, Private Pension Scheme, Provident Fund

description: Highly engineered materials are arousing great interest because of their ability to manipulate heat, as described by coordinate transformation approach. Based on the recently developed analog gravity models, this paper presents how a simple device based on nematic liquid crystal can achieve in principle either thermal concentration or expulsion. These outcomings are shown to stem from topological properties of a disclination-like structure, induced in the nematic by anchoring conditions.

description: We study the mechanical properties of two-dimensional (2D) boron, borophenes, by first-principles calculations. The recently synthesized borophene with 1/6 concentration of hollow hexagons (HH) is shown to have in-plane modulus C up to 210 N/m and bending stiffness as low as D = 0.39 eV. Thus, its Foppl-von Karman number per unit area, defined as C/D, reaches 568 nm-2, over twofold higher than graphene's value, establishing the borophene as one of the most flexible materials. Yet, the borophene has a specific modulus of 346 m2/s2 and ideal strengths of 16 N/m, rivaling those (453 m2/s2 and 34 N/m) of graphene. In particular, its structural fluxionality enabled by delocalized multi-center chemical bonding favors structural phase transitions under tension, which result in exceptionally small breaking strains yet highly ductile breaking behavior. These mechanical properties can be further tailored by varying the HH concentration, and the boron sheet without HHs can even be stiffer than graphene against tension. The record high flexibility combined with excellent elasticity in boron sheets can be utilized for designing composites and flexible systems.

description: This study aims at measuring customer satisfaction of the Ethiopian Electric Utility company Services at North Addis Ababa region in both technical and customer services. The study reveals that there is a moderate customer satisfaction in two technical services; electricity tariffs, billing methods, and poor customer satisfaction in failure fixing and new connection. The major problems in the technical services provided by Ethiopian electric utility are; handling disputed bills and the long time needed for fixing electricity failure and power supply connection. On the other hand, the study shows that there is a moderate satisfaction in payment method, the length of waiting time in the company offices, and accessibility of customer offices of EEU. Respondents have a poor satisfaction with the remaining five services ; replies of employees to customer telephone calls, about information and guidance provided to customers, in complaint handling, in continuity of power supply and good quality of power. The customers' also very poor satisfaction to prior intimidation of power cut. Finally, respondents think that the overall performance of Ethiopian Electric Utility Company in general is poor. The residential customers are the most satisfied group followed by the commercial then the industrial. Therefore, the EEU should come up with an appropriate service delivery standards; proper complaint handling mechanisms; improve the technical department service delivery to new connection, failure fixing and improve billing service ; relevant training for its front line and technical employees; developing various payment mechanism; informing customer about planned interruption; reduce power interruption and fluctuation to the standard; upgrade and maintain its old transmission, substation and distribution network systems; improve its generation capacity and adequate resource management in order to meet customer satisfaction.

Entropy Production in a Lepton-Photon Universe

description: We look at the entropy production during the lepton era in the early Universe by using a model where we exclude all particles except the leptons and photons. We assume a temperature dependent viscosity as calculated recently by one of us (Husdal 2016) with use of relativistic kinetic theory. We consider only the bulk viscosity, the shear viscosity being omitted because of spatial isotropy. The rate of entropy production is highest just before the neutrinos decouple. Our results show that the increase in entropy during the lepton era is quite small, about 0.071 % at a decoupling temperature of $T=10^{10}~\mathrm{K}$. This result is slightly smaller than that obtained earlier by Caderni and Fabbri (1977). After the neutrino decoupling, when the Universe has entered the photon era, kinetic-theory arguments no longer support the appearance of a bulk viscosity. At high temperatures and a stable particle ratio, entropy production (d$σ$/d$T$) goes as $T^{-8}$, with the total entropy ($Δσ$) increasing as $T^{-7}$. These rates go slightly down just before the neutrinos decouple, where $Δσ\propto T^{-6.2}$.

The Contributions of the Comprehensive Justice System Reform Program in Improving Access to Justice: The Case of the Federal Courts in Addis Ababa
Creators: name: Demissew, Tefera
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Access to justice is one of the fundamental rights of citizens. It enables citizens to enforce their rights in cases of infrigment of rights by going to a court of law and seeking remedy. However, different barriers to access to justice impede citzens from going to courts and enforcing their rights. The denial of the basic right of access to justice of citizens forces citizens to take the law in to their hands. This leads to rise of conflict and instability in a country(Pietro et al, 2014, p.15). Therefore, states should work to eliminate or reduce the barriers to access to justice through justice reforms. The government in Ethiopia also initiated the JSRP (later called CJSRP)to eliminate or reduce the barriers to access to justice and improve access to justice in Ethiopia. And this research tries to identify the contributions of the CJSRP in eliminating or reducing the barriers to access to justice and improving the access to justice of the Federal Courts in Addis Ababa City Adminstration.

description: The instanton partition functions of $\mathcal{N}=1$ 5d super Yang-Mills are built using elements of the representation theory of quantum $\mathcal{W}_{1+\infty}$ algebra: Gaiotto state, intertwiner, vertex operator. This algebra is also known under the names of Ding-Iohara-Miki and quantum toroidal $\widehat{\mathfrak{gl}}(1)$ algebra. Exploiting the explicit action of the algebra on the partition function, we prove the regularity of the 5d qq-characters. These characters provide a solution to the Schwinger-Dyson equations, and they can also be interpreted as a quantum version of the Seiberg-Witten curve.
