Comparative study on the utilization of reproductive health services and factors affecting it among students with and without disabilities in public Universities in Addis Ababa, Ethiopia
Creators: name: Meshesha, Selamawit
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Reproductive health services (RHS) and health education are fundamental human rights. However, utilization of reproductive health services among adolescents and youth is low. Particularly, people with disabilities have lower knowledge on reproductive health related issues and service utilization. Objective: The objective of this study is to compare reproductive health service utilization and assess factors affecting it among students with and without disabilities in public Universities in Addis Ababa, Ethiopia. Method: Institution based comparative cross sectional study was carried out in two public higher learning institutions in Addis Ababa from September 2016 to June 2017. Multi stage sampling was used to select a total of 548 respondents. The data analysis was done using STATA version 14 software. Odds ratio, 95% CI in conditional logistic regression was used to identify associated factors with RHS utilization. Result: The RHS utilization among students with and without disabilities were 40.52% & 69.1% respectively. RHS accessibility and awareness were the main reasons for not utilizing RHS among students with disabilities whereas religious and cultural barriers were reasons for students without disabilities. Those students without disabilities were (AOR=3.11: 1.86, 5.19) times more likely to utilize RHS than those students with disabilities. For students with disabilities those who knew RHS providing facilities [AOR=4.9: 1.47, 16.2], who ever had sex [AOR=30.1: 9.6, 94.4], who ever had discussed RH issues with any one [AOR=3.59: 1.6, 7.9], who were exposed to any type of mass media in the last 12 months [AOR=2.9: 1.03, 8.1] and who had a nearby health facility as other health facilities [AOR=4.36: 1.01, 18.7] were more likely to utilize RHS. For students without disabilities those students who were in the age group of 25 and above were [AOR=5.01: 1.19, 21.2] times and those students who had ever had a girl\boyfriend were [AOR=6.65: 3.2, 13.2] times more likely to utilize RHS than those who were in the age group 15-19 years and those who had never had a girl\boyfriend respectively. Conclusion and recommendation: reproductive health service utilization among students with disabilities is low compared with those students without disabilities. Awareness on RHS provision facilities, ever having sex, discussion on RH issues, mass media exposure in the past 12 months, availability of other HFs than University clinic were found to be significantly associated with RHS use among students with disabilities while age and having a boy/girl friend were the predictors of RHS use among students without disabilities. All stakeholders on RH working with people with disabilities should focus on awareness creation through mass media, discussion and training to increase the RHS utilization level.

description: Whenever a given Poisson manifold is equipped with discrete symmetries the corresponding algebra of invariant functions or the algebra of functions twisted by the symmetry group can have new deformations, which are not captured by Kontsevich Formality. We consider the simplest example of this situation: $\mathbb{R}^2$ with the reflection symmetry $\mathbb{Z}_2$. The usual quantization leads to the Weyl algebra. While Weyl algebra is rigid, the algebra of even or twisted by $\mathbb{Z}_2$ functions has one more deformation, which was identified by Wigner and is related to Feigin's $gl_λ$ and to fuzzy sphere. With the help of homological perturbation theory we obtain explicit formula for the deformed product, the first order of which can be extracted from Shoikhet-Tsygan-Kontsevich formality.

description: We investigate the ground state nature of the transverse field Ising model on the $J_1-J_2$ square lattice at the highly frustrated point $J_2/J_1=0.5$. At zero field, the model has an exponentially large degenerate classical ground state, which can be affected by quantum fluctuations for non-zero field toward a unique quantum ground state. We consider two types of quantum fluctuations, harmonic ones by using linear spin wave theory (LSWT) with single-spin flip excitations above a long range magnetically ordered background and anharmonic fluctuations, by employing a cluster-operator approach (COA) with multi-spin cluster type fluctuations above a non-magnetic cluster ordered background. Our findings reveal that the harmonic fluctuations of LSWT fail to lift the extensive degeneracy as well as signaling a violation of the Hellmann-Feynman theorem. However, the string-type anharmonic fluctuations of COA are able to lift the degeneracy toward a string-valence bond solid (VBS) state, which is obtained from an effective theory consistent with the Hellmann-Feynman theorem as well. Our results are further confirmed by implementing numerical tree tensor network simulation. The emergent non-magnetic string-VBS phase is gapped and breaks lattice rotational symmetry with only two-fold degeneracy, which bears a continuous quantum phase transition at $Γ/J_1 \cong 0.50$ to the quantum paramagnet phase of high fields. The critical behavior is characterized by $ν\cong 1.0$ and $γ\cong 0.33$ exponents.

description: Neutrino self-interactions in a dense neutrino gas can induce collective neutrino flavor conversions. Fast neutrino flavor conversions (FFCs), one of the collective neutrino conversion modes, potentially change the dynamics and observables in core-collapse supernovae and binary neutron star mergers. In cases without neutrino-matter interactions (or collisions), FFCs are essentially energy-independent, and therefore the single energy treatment has been used in previous studies. However, neutrino-matter collisions in general depend on neutrino energy, suggesting that energy-dependent features may emerge in FFCs with collisions. In this paper, we perform dynamical simulations of FFCs with iso-energetic scatterings (emulating nucleon scatterings) under multi-energy treatment. We find that cancellation between in- and out-scatterings happens in high energy region, which effectively reduces the number of collisions and then affects the FFC dynamics. In fact, the lifetime of FFCs is extended compared to the single-energy case, leading to large flavor conversions. Our result suggests that the multi-energy treatment is mandatory to gauge the sensitivity of FFCs to collisions. We also provide a useful quantity to measure the importance of multi-energy effects of collisions on FFCs.

description: We report the protocol for a scoping review that forms the first step in the process of generating a core outcome set (COS) for evaluating perioperative services utilising comprehensive geriatric assessment (CGA). By systematically searching the literature comparing perioperative CGA to routine surgical care which has been published since the year 2000, we aim to extract and summarise the outcome measures used by previous trials in this field to generate a preliminary outcome set. This will be supplemented by input from experts within the field, and reviewed through iterative Delphi rounds or through nominal group technique until consensus is achieved. The results of this review, and the associated Delphi or nominal group consensus, will be instrumental in the design of future trials evaluating the implementation of CGA within perioperative pathways. We also hope that it will identify gaps within the current evidence base for future research.

description: Background: American football players need the ability to provide maximal muscular power in a modicum of time. Postactivation performance enhancement (PAPE), which is characterized by an acute improvement of a performance measure following conditioning contractions, could be of value for American football players. The aim of the present study was to determine the effect of a heavy load back squat PAPE protocol on three-point explosion (TPE; an essential blocking technique and drill) and 40-yard dash (40YD) performance compared to a traditional warm-up in American football players. Methods: In a crossover study design, eighteen male competitive regional league American football players (mean ± SD: body mass 93.9 ± 15.5 kg, height 181.4 ± 6.8 cm, age 24.8 ± 3.9 years) performed a TPE on a double blocking sled (weight: 150 kg) and a 40YD (36.6 m with a 5 and 10 m split) 8 min after two different warm-up conditions. One condition was a traditional, football specific warm-up (TWU) consisting of game related movements (e.g. backward lunges, lateral power steps), whereas the other condition (PAPE) consisted of three explosive back squats with a load of 91 % one-repetition maximum. Results: There was no significant difference in TPE between TWU and PAPE. For the 40YD, we found significantly shorter sprint times in the PAPE condition with medium effect sizes for the 5 m (p = 0.007; r = 0.45) and 10 m (p = 0.020; r = 0.39) but not for the whole 36.6 m distance (p = 0.084; r = 0.29) compared to the TWU condition. Conclusions: The used heavy load back squat PAPE protocol improved sprint performance over short distances (≤ 10 m) but not complex movements like the three-point explosion.

description: Isolated complex networks have been studied deeply in the last decades due to the fact that many real systems can be modeled using these types of structures. However, it is well known that the behavior of a system not only depends on itself, but usually also depends on the dynamics of other structures. For this reason, interacting complex networks and the processes developed on them have been the focus of study of many researches in the last years. One of the most studied subjects in this type of structures is the Synchronization problem, which is important in a wide variety of processes in real systems. In this manuscript we study the synchronization of two interacting scale-free networks, in which each node has $ke$ dependency links with different nodes in the other network. We map the synchronization problem with an interface growth, by studying the fluctuations in the steady state of a scalar field defined in both networks. We find that as $ke$ slightly increases from $ke=0$, there is a really significant decreasing in the fluctuations of the system. However, this considerable improvement takes place mainly for small values of $ke$, when the interaction between networks becomes stronger there is only a slight change in the fluctuations. We characterize how the dispersion of the scalar field depends on the internal degree, and we show that a combination between the decreasing of this dispersion and the integer nature of our growth model are the responsible for the behavior of the fluctuations with $ke$.

description: We employ an appropriate perturbative scheme in the large viscous regime to study oscillating states in driven Langevin systems. We explicitly determine oscillating state distribution of under-damped Brownian particle subjected to thermal, viscous and potential drives to linear order in anharmonic perturbation. We also evaluate various non-equilibrium observables relevant to characterize the oscillating states. We find that the effects of viscous drive on oscillating states are measurable even in the leading order and show that the thermodynamic properties of the system in these states are immensely distinct from those in equilibrium.

description: Topological phases of matter have remained an active area of research in the last few decades. Periodic driving is known to be a powerful tool for enriching such exotic phases, which leads to various phenomena with no static analogs. One such phenomenon is the emergence of the elusive $pi/2$ modes, i.e., a type of topological boundary state pinned at a quarter of the driving frequency. The latter may lead to the formation of Floquet parafermions in the presence of interaction, which is known to support more computational power than Majorana particles. In this work, we experimentally verify the signature of $π/2$ modes in an acoustic waveguide array, which is designed to simulate a square-root periodically driven Su-Schrieffer-Heeger model. This is accomplished by confirming the $4T$-periodicity ($T$ being the driving period) profile of an initial-boundary excitation, which we also show theoretically to be the smoking gun evidence of $π/2$ modes. Our findings are expected to motivate further studies of $π/2$ modes in quantum systems for potential technological applications.

description: Background: Due to the failure of proper healthcare resource allocation and poor affordability to health services, many citizens are exposed to impoverishment from health shocks and catastrophic out of pocket health expenditure. The poorest households even abstain from seeking health care. In order to reverse this scenario and meet universal health coverage, a pilot community based health insurance (CBHI) scheme was launched in Ethiopia in 2011. Objective: The main objective of the study is to examine factors influencing participation in a community based health insurance scheme in Bambasi Woreda of Benishangul Gumuz region. Method: The study was community based cross sectional quantitative type undertaken in Bambasi Woreda of Benishangul gumuz region. Using two–stage sampling technique, 614 sample households were selected and used for the analysis. After the data is fed into Epi Info 3.7.0, STATA 14 software was applied to clean and analyze the data. The data were analyzed by frequency tables, summary statistics and logistic regression model. Results: It is found that 55% of sample households are members of the pilot community based health insurance scheme. 85% of the respondents have information about the recently introduced scheme. The multivariate analysis reveals a number of factors drive enrollment to the scheme. Willingness to join the scheme was more likely among the rich households as compared to the poor (AOR of 95% AOR of CI 2.719(1.144, 6.464). Those who have no awareness on the scheme are less likely to participate than those who have (AOR of 95 % CI (0.051(0.012, 0.212)). Participation to the scheme is also found to be more likely among those who have confidence on commitment of CBHI officials and who accept the benefit packages. Furthermore, illness episode was positivity associated with uptake of CBHI (AOR of 95% CI4.407 (1.802, 10.777) Conclusions &recommendation: It is concluded that awareness, family size, illness episodes, level of income, benefit packages, distance from health facility were factors influencing participation in a CBHI.The Study also indicates the importance of enhancing awareness, create confidence on the commitment of the scheme officials, and make the benefit package according to the expectation of the community in order to boost uptake of CBHI scheme. It is also noted that adverse selection could be a threat to the financial sustainability of the scheme.

description: The asymmetric collapse of cavitation bubbles near a solid substrate generates large wall shear stresses, the precise magnitude of which is still not known with certainty. By comparing numerical simulations and experiments of a laser-induced cavitation bubble near a solid substrate, we demonstrate that an accurate measurement of the pressure pulse emitted during bubble inception and of the maximum bubble radius allow a unique initialisation of the simulation. This allows an accurate reproduction of the asymmetric collapse, with reliable predictions of the shear stress and pressure generated at the substrate.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1991

description: A field trial to initiate modern contraception (MC) was conducted in Kotebe Awraja, Addis Ababa Administrative Region, between August 1990 and January 1991. The purpose of the field trial was to examine what effect involving husbands in a family planning (FP) intervention program would have on the initiation of modern contraception (MC) by the couple. A total of 528 married women aged 15-49 were included in the study, randomly divided into two groups on the basis of "blocked" assignments to home visitors. The experimental group, totalling 267 received the intervention package with their husbands, while the control group, totalling 261 received the intervention package without the involvement of their husbands. The FP intervention package was the same . A baseline interview conducted to assess socio-demographic, reproducti ve, knowledge and attitudes of the wives, as well as of their husbands prior to group assignment did not reveal any statistically significant differences between the experimental and control groups. Of the 528 married couples who were entered into the study, 106 initiated MC. A statistically significant higher propor tion of couples in the experiment group initiated MC as compared to those in the control group. (relative risk 1.61), 95% vii CI (1.13, 2.3), p < .007 . The younger age of wife and husband, higher educational level of wife, greater number of barriers identified to use MC, and having a husband's support were positively associated with the verified initiation of MC. It is concluded that FP programs for married women of reproductive age which include husbands have a higher degree of success than those only directed to wives. It is therefore recommended that future family planning programs should include men and that further investigation of its effectiveness be implemented .

The interferometric HI data for this sample were collected from available archives and supplemented with new GMRT observations. This paper describes an uniform analysis of the HI kinematics of this inhomogeneous data set. Our main result is an atlas for our calibrator sample that presents global HI profiles, integrated HI column-density maps, HI surface density profiles and, most importantly, detailed kinematic information in the form of high-quality rotation curves derived from highly-resolved, two-dimensional velocity fields and position-velocity diagrams.

description: The combinatorial integral approximation (CIA) decomposition suggests solving mixed-integer optimal control problems by solving one continuous nonlinear control problem and one mixed-integer linear program (MILP). Unrealistic frequent switching can be avoided by adding a constraint on the total variation to the MILP. Within this work, we present a fast heuristic way to solve this CIA problem and investigate in which situations optimality of the constructed feasible solution is guaranteed. In the second part of this article, we show tight bounds on the integrality gap between a relaxed continuous control trajectory and an integer feasible one in the case of two controls. Finally, we present numerical experiments to highlight the proposed algorithm’s advantages in terms of run time and solution quality.

description: We report on the experimental implementation of a spin pump with ultracold bosonic atoms in an optical superlattice. In the limit of isolated double wells it represents a 1D dynamical version of the quantum spin Hall effect. Starting from an antiferromagnetically ordered spin chain, we periodically vary the underlying spin-dependent Hamiltonian and observe a spin current without charge transport. We demonstrate a novel detection method to measure spin currents in optical lattices via superexchange oscillations emerging after a projection onto static double wells. Furthermore, we directly verify spin transport through in-situ measurements of the spins' center of mass displacement.

description: Inclusion of incidence data in the surveillance system of HIV is important in order to generate accurate data for effective prevention and control of the pandemic. Retrospective cross-sectional HIV seroprevalence and seroincidence survey was conducted to determine the magnitude of Primary HIV Infection (PHI) and, to identify and describe factors associated with it on stored sera of 455 STIs cases that had been collected and stored during the validation study of syndromic case management algorithms for STIs in Ethiopia, between January - May 2003. Standard HIV-antibody tests were done on all sera and IgG-capture BED-EIA on positive samples for detecting recent infections. Negative Serum samples for HIV antibodies were screened by nucleic acid amplification (HIV RNA PCR) for viral RNA. Incidence was calculated using the consensus formula. OR with 95% CI was used to measure the degree of association between associated factors and PHI and, logistic regression analysis was done to identify predictors of PHI. The overall HIV1/2 seropositivity was found to be 33% and the rate varies among the major STI syndromes, namely, VDS(35%), UDS(20.2%) and GUS(60.5%). Out of the 150 HIV antibody positive cases 15 (prevalence, 3.3%) were recently infected and, annual HIV incidence was estimated to be 11.8% (95% CI, 6.02, 17.58). Acute HIV infection was detected in 7 cases (prevalence, 1.5%) out of 305 HIV antibody negative sera indicating that standard HIV-antibody tests detected only 95.5% of the total HIV infections. The over all prevalence of PHI was 4.8%. Considering both recent and acute infections annual HIV incidence was estimated to be10.1% (95% CI, 5.13 - 14.97). Diagnosis of syphilis was found to be an independent risk factor for PHI for both sexes. Age group 35 – 39 years in males was found to be significantly associated with PHI. The estimated high incidence (10.1%) of HIV-1 infection in this study population indicated that HIV infection is still spreading and targeted intervention is highly recommended. Strong and sustained Provider Initiated HIV Counseling and Testing (PIHCT) with subsequent follow up is recommended for STI patients, particularly those with GUS, during their first appearance at health institutions.

description: Solving mixed-integer nonlinear optimization problems (MINLPs) to global optimality is extremely challenging. An important step for enabling their solution consists in the design of convex relaxations of the feasible set. Known solution approaches based on spatial branch-and-bound become more effective the tighter the used relaxations are. Relaxations are commonly established by convex underestimators, where each constraint function is considered separately. Instead, a considerably tighter relaxation can be found via so-called simultaneous convexification, where convex underestimators are derived for more than one constraint function at a time. In this work, we present a global solution approach for solving mixed-integer nonlinear problems that uses simultaneous convexification. We introduce a separation method that relies on determining the convex envelope of linear combinations of the constraint functions and on solving a nonsmooth convex problem. In particular, we apply the method to quadratic absolute value functions and derive their convex envelopes. The practicality of the proposed solution approach is demonstrated on several test instances from gas network optimization, where the method outperforms standard approaches that use separate convex relaxations.

description: The notion of Isolated Horizons has played an important role in gravitational physics, being useful from the characterization of the endpoint of black hole mergers to (quantum) black hole entropy. In particular, the definition of {\it weakly} isolated horizons (WIHs) as quasilocal generalizations of event horizons is purely geometrical, and is independent of the variables used in describing the gravitational field. Here we consider a canonical decomposition of general relativity in terms of connection and vierbein variables starting from a first order action. Within this approach, the information about the existence of a (weakly) isolated horizon is obtained through a set of boundary conditions on an internal boundary of the spacetime region under consideration. We employ, for the self-dual action, a generalization of the Dirac algorithm for regions with boundary. While the formalism for treating gauge theories with boundaries is unambiguous, the choice of dynamical variables on the boundary is not. We explore this freedom and consider different canonical formulations for non-rotating black holes as defined by WIHs. We show that both the notion of horizon degrees of freedom and energy associated to the horizon is not unique, even when the descriptions might be self-consistent. This represents a generalization of previous work on isolated horizons both in the exploration of this freedom and in the type of horizons considered. We comment on previous results found in the literature.

description: Here, we present an extension to our previously published structural ultrahigh resolution T1-weighted magnetic resonance imaging (MRI) dataset with an isotropic resolution of 250 μm, consisting of multiple additional ultrahigh resolution contrasts. Included are up to 150 μm Time-of-Flight angiography, an updated 250 μm structural T1-weighted reconstruction, 330 μm quantitative susceptibility mapping, up to 450 μm structural T2-weighted imaging, 700 μm T1-weighted back-to-back scans, 800 μm diffusion tensor imaging, one hour continuous resting-state functional MRI with an isotropic spatial resolution of 1.8 mm as well as more than 120 other structural T1-weighted volumes together with multiple corresponding proton density weighted acquisitions collected over ten years. All data are from the same participant and were acquired on the same 7 T scanner. The repository contains the unprocessed data as well as (pre-)processing results. The data were acquired in multiple studies with individual goals. This is a unique and comprehensive collection comprising a “human phantom” dataset. Therefore, we compiled, processed, and structured the data, making them publicly available for further investigation.

description: Models based on the extended $SU(3)_{C}\times SU(3)_{L}\times U(1)_{X}$ (331) gauge group usually follow a common pattern: two families of left-handed quarks are placed in anti-triplet representations of the $SU(3)_{L}$ group; the remaining quark family, as well as the left-handed leptons, are assigned to triplets (or vice-versa). In this work we present a flipped 331 model where this scheme is reversed: all three quarks families are in the same representation and it is the lepton families which are discriminated by the gauge symmetry. We discuss fermion masses and mixing, as well as $Z'$ interactions, in a minimal model implementing this idea.

description: Urbanization can affect species communication by introducing new selection pressures, such as noise pollution and different environmental transmission properties. These selection pressures can trigger divergence between urban and non-urban populations. Songbirds rely on vocalizations to defend territories and attract mates. Urban songbirds have been shown in some species and some populations to increase the frequencies, reduce the length and change other temporal features of their songs. This study compares songs from four urban and three non-urban populations of dark-eyed juncos (Junco hyemalis) throughout Southern California. We examined song length, trill rate, minimum frequency, maximum frequency, peak frequency and frequency bandwidth. We also compared songs recorded from one urban junco population in San Diego nearly two decades ago with recently collected data in 2018–2020. Overall comparisons, we only found significant differences between UCLA and the 2006/2007 UCSD field seasons in minimum and maximum frequencies. These findings partially support and are partially in contrast to previous urban song studies. As urban areas expand, more opportunities will arise to understand urban song divergence in greater detail.

description: Introduction:Intracranial and spinal mass lesions are an important cause of neurological morbidity and common indication for cross sectional imaging. Given the wide range of pathological cases that can present as intra cranial mass lesions, the radiologist has an important role in limiting the differential diagnosis in clinical decision making process and in further management of cases. so far there are few reports on radiological and histological and pathology correlation done in Ethiopia and no report done giving emphasis on cases discussed on inter-departmental management session ; like , pre-operative Neurosurgery and radiological session. Thus, this research contribute the knowledge of the imaging appearance of various intracranial tumors and subsequently to improve the diagnostic accuracy and role of radiology in the management decision . Objectives:To assess the correlation of preoperative radiological diagnosis of lesions with histological diagnosis in TikurAnbesahospital , Addis Abebea , Ethiopia , from January 2016 to August 2017 G.C. Methods:Hospital based prospective cross- sectional study was conducted on 78 patients who underwent surgery for the intra-cranial and spinal lesions at TikurAnbessa Specialized Hospital in a period of 21 months from January 2016 to August 2017 G.C. Patients included here are those who had either CT or MRI or both report with confirmed histopathology result. Result:There was morethan 80 % of concordance between pre operative radiologic diagnosis and histological diagnosis based on based on top diagnosis and first differential diagnosis given on neuro- radiology and neurosurgery joint session discussion in imaging evaluation of Glial tumor , Menigioma and Sellar/Parasellarregin tumors. Conclusion:Glial tumor and Meningioma were the most frequent intracranial tumors presented. It was seen that pre operative radiologic diagnosis accuracy was high for most of intracranial tumor.
