Community Capitals and Community Resilience in Rural Oromia, Ethiopia: The Case of East Hararghe

Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2016

description: Community resilience, i.e., the ability of a community to utilize available resources to respond to, withstand, and recover from adverse situations, highly depends on the condition of community capitals. This paper examines the state of community capitals, considering the case of the rural community in East Hararghe. Data were gathered through in-depth interviews, key informant interviews, focus group discussions, and observations. The findings show that the stocks of the various capitals of the community are too low to contribute to moderate resilience. The negative interplay of the capitals of the community has led to a spiralling-down effect on each capital and exposed the community to severe vulnerability in the face of frequent shocks and disturbances. To reverse this condition and improve the resilience of the community, the results indicate the importance of first dealing with the long-established experiences of the community which are locking up community capitals and hence blocking community resilience; before attempting any other intervention. “Training for Transformation” is, therefore, suggested to be given to the community to enable it to reflect critically on its current situation and the cognitive and cultural impediments to change. This is expected to assist the community to integrate outside interventions productively and to increase its capabilities in using its own resources in its local environment.

description: We present experimental work for improved atom loading in the optical molasses of a caesium fountain clock, employing a low-velocity intense source of atoms (LVIS) [Lu et al., Phys. Rev. Lett. 77, 3331 (1996)], which we modified by adding a "dark" state pump laser. With this modification the atom source has a mean flux of $4 \times 10^{8}$ atoms/s at a mean atom velocity of $8.6$ m/s. Compared to fountain operation using background gas loading, we achieved a significant increase of the loaded and detected atom number by a factor of 40. Operating the fountain clock with a total number of detected atoms $N_{\mathrm{at}}=2.9 \times 10^6$ in the quantum projection noise-limited regime, a frequency instability $σ_y\left(1\text{s}\right)=2.7 \times 10^{-14}$ was demonstrated.

Combating Impunity While Challenging International Criminal Court: The African Paradox

description: International criminal justice has faced a stiff challenge in Africa since recently. Despite the original overwhelming backing for the International Criminal Court (ICC), now Africa is pulling back its support. When the African Union (AU) celebrated its 50th year anniversary in Addis Ababa in October 2013, AU condemned the ICC as ‘a tool of neo-colonialism and racist institution’ unfairly targeting Africans. Consequently, it initiated a withdrawal of African states from the ICC membership, the transfer of cases pending before ICC to 'African courts'- including the newly established African Court of Justice and Human Rights. In principle, holding prosecutions in national courts is preferable. However, the local prosecution of perpetrators of international crimes is mostly impractical when the accused are the seating heads/high-ranking government officials. In one way, the judicial systems of most African countries lack a capacity to manage intricate criminal proceedings. Besides, governments do not want to see the prosecution of their officials- shielding them against criminal responsibility and embarrassment. The recent AU's effort to withdraw its member states from ICC and requesting them to decline cooperation shows the aggravating friction between the two - reversing the African states previous great support for the ICC and blurring their promise to fight impunity and human rights violations. This article, by scrutinizing the prospects of AU’s suggested modifications to the status quo relationship between Africa and the ICC, takes the position that AU should not contradict its commitment to combat impunity by invoking the distorted ‘neo-colonial argument’ against the ICC.

Year: 2016

description: The purpose of this study was to investigate the preferred leadership frame of two female primary school principals. A mixed method study design was employed sequentially. The quantitative method informed the qualitative method. Fifty-two teachers (70.8%) were involved in the quantitative part of the study and seven others (one female principal, two department heads, two teachers, and two vice-principals) were involved in the qualitative part of the study. Leadership Orientations Questionnaire (LOQ) developed by Bolman and Deal (1991), Semi-structured interview, and observation were instruments of data collection. The data were analyzed using percentages, mean, SD and independent sample t-test with the help of SPSS. The results showed that Muuxannoo school female principal was multi-frame by orientation to a higher extent (structural, human resources, political and Symbolic) whereas Daawoo school principal was moderate in using all the four leadership frames. When respondents were compared by sex on how they perceive their female principal, male teacher respondents rated higher whereas the female teacher respondents rated them moderate in all the four frames. Among the recommendations, the single frame female principal and others having similar behavior and action needed to size up their lenses so that they understand the complex school environment and meet their requirements.

description: Knee dislocation is a rather uncommon injury that happens quite seldomly with an estimated annual incidence of 2.3 per 1 million of all orthopedic trauma. (Georgiadis et al., 2013). Posterior knee dislocation is the second most often knee dislocation according to available bibliography and according to Kennedy (KENNEDY, 1963) it occurs when the tibia is forced posteriorly on the femur. Although it is a rare traumatic injury , action must be taken immediately given the high chances of vascular injury that can put the limb at risk. (Georgiadis et al., 2013; Karkos et al., 2018).This paper will examine the mechanisms of injury that can lead to knee dislocations and specifically to a posterior dislocation, the need for quick and effective recognition of vascular and neurological injuries, the available treatment options for optimal limb salvage as well as the results of the undertaken interventions

description: Rural women in Oromia engage in different economic activities that contribute tremendously to the livelihood of their families. Nevertheless, rural women’s contribution to the rural economy is far behind expectation due to many challenges. This paper, therefore, intends to investigate the factors that hamper rural women’s involvement in the economy with particular emphasis on the rural women in eastern Oromia. In this study, both quantitative and qualitative research methods were employed. The major barriers to women’s involvement in the economy were identified using interview schedule, in-depth interviews, focus group discussions, and non-participatory observations. The finding indicates that factors emanating from the socio-cultural traditions of the community such as men’s view towards women, women’s view of themselves, the burden on women in childbearing and rearing, women’s lack of access to valuable resources and education have daunting effects on women’s involvement in the economy. Moreover, the finding also shows that the religion of the community which also upholds patriarchal values has a detrimental effect on women’s involvement in the economy. Hence, the study recommends that improving the involvement of rural women in the economy requires the transformation of the cultural traditions and religious outlooks of the community, women’s practical access to resources particularly land. Above all, the study recommends that there should be a sound policy framework that can ensure the education of both men and women to bring about the actual emancipation of women in the economic sphere.

description: We study the 2010 specific version of the 2002 proposed $U(1)_X$ extension of the supersymmetric standard model, which has no $μ$ term and conserves baryon number and lepton number separately and automatically. We consider in detail the scalar sector as well as the extra $Z_X$ gauge boson, and their interactions with the necessary extra color-triplet particles of this model, which behave as leptoquarks. We show how the diphoton excess at 750 GeV, recently observed at the LHC, may be explained within this context. We identify a new fermion dark-matter candidate and discuss its properties. An important byproduct of this study is the discovery of relaxed supersymmetric constraints on the Higgs boson's mass of 125 GeV.

description: Few-mode fiber amplifier is widely under study to overcome the issue of internet traffic in optical communication. This article proposes annulus core few-mode erbium doped fiber (FM-EDF) with annulus or extra annulus doping for amplification of the LP01, LP11, LP21, and LP31 signal mode groups with low differential modal gain (DMG). Our simulations confirm that extra annulus doping helps in reducing DMG of higher order mode groups. We have achieved less than 2.2 dB DMG over C-band for 4-mode groups using extra annulus doping. The proposed EDF would be useful for space division multiplexing (SDM) based optical fiber communication system.

description: In order to understand the rate of merger of stellar-mass black hole binaries (BHBs) by gravitational wave (GW) emission it is important to determine the major pathways to merger. We use numerical simulations to explore the evolution of BHBs inside the radius of influence of supermassive black holes (SMBHs) in galactic centers. In this region the evolution of binaries is dominated by perturbations from the central SMBH. In particular, as first pointed out by Antonini and Perets, the Kozai-Lidov (KL) mechanism trades relative inclination of the BHB to the SMBH for eccentricity of the BHB, and for some orientations can bring the BHB to an eccentricity near unity. At very high eccentricities, GW emission from the BHB can become efficient, causing the members of the BHB to coalesce. We use a novel combination of two N-body codes to follow this evolution. We are forced to simulate small systems to follow the behavior accurately. We have completed 400 simulations that range from $\sim$ 300 stars around a $10^{3}$ M$_{\odot}$ black hole to $\sim$ 4500 stars around a $10^{4}$ M$_{\odot}$ black hole. These simulations are the first to follow the internal orbit of a binary near a SMBH while also following the changes to its external orbit self-consistently. We find that this mechanism could produce mergers at a maximum rate per volume of $\sim 100$ Gpc$^{-3}$ yr$^{-1}$ or considerably less if the inclination oscillations of the binary remain constant as the BHB inclination to the SMBH changes, or if the binary black hole fraction is small.

description: We report the experimental observation of longitudinal spin Seebeck effect in a multiferroic helimagnet Ba0.5Sr1.5Zn2Fe12O22. Temperature gradient applied normal to Ba0.5Sr1.5Zn2Fe12O22/Pt interface generates inverse spin Hall voltage of spin current origin in Pt, whose magnitude was found to be proportional to bulk magnetization of Ba0.5Sr1.5Zn2Fe12O22 even through the successive magnetic transitions among various helimagnetic and ferrimagnetic phases. This finding demonstrates that the helimagnetic spin wave can be an effective carrier of spin current. By controlling the population ratio of spin-helicity domains characterized by clockwise/counter-clockwise manner of spin rotation with use of poling electric field in the ferroelectric helimagnetic phase, we found that spin-helicity domain distribution does not affect the magnitude of spin current injected into Pt. The results suggest that the spin-wave spin current is rather robust against the spin-helicity domain wall, unlike the case with the conventional ferromagnetic domain wall.

description: By making a brief historical survey on the evolution of Tourism in the Lake Tana region, this paper assesses major challenges and bottlenecks that have served as obstacle to tap the region’s tourism potential. The objective of the study is to identify the major challenges that encountered tourism in a historical perspective and to suggest possible solutions to tackle the problems. To that end, data were collected from both primary and secondary sources. Firsthand information was gathered using inventory field survey and intensive reading in the archives of different institutions and through guided interview from knowledgeable informants. Data gathered was analyzed qualitatively in a historical method. This paper concludes that the tourism industry in Lake Tana region is not effectively managed and its high tourism resource potential is underutilized.

description: Fe3C/few-layered graphene core/shell nanoparticles embedded in a carbon matrix are synthesized by a novel two-step surfactant sol-gel strategy, where the processes of hydrolysis, polycondensation and drying take place in a one-pot. The present approach is based on the combined action of oleic acid and oleylamine, which act sterically on the precursor micelles when a densification temperature is performed in a reducing atmosphere. The structural and magnetic evolution of the formed compounds is investigated, ranging from iron oxides such as Fe3O4 and FeO, to the formation of pure Fe3C/C samples from 700 °C onwards. Interestingly, Fe3C nanoparticles with a size of ~20 nm crystallize immersed in the carbon matrix and the surrounding environment forms an oriented encapsulation built by few-layered graphene. The nanostructures show a saturation magnetization of ~43 emu/g and a moderate coercivity of ~500 Oe. Thereby, an innovative chemical route to produce single phase Fe3C nanoparticles is described, and an effective method of few-layered graphene passivation is proposed, yielding a product with a high magnetic response and high chemical stability against environmental corrosion.

description: In protoplanetary disks, CO$_2$ is solid ice beyond its snow line at $\sim 10 \rm AU$. Due to its high abundance, it contributes heavily to the collisional evolution in this region of the disk. For the first time, we carried out laboratory collision experiments with CO$_2$ ice particles and a CO$_2$-covered wall at a temperature of 80 K. Collision velocities varied between 0 - 2.5 m/s. Particle sizes were on the order of $\sim$ 100 $μ$m. We find a threshold velocity between the sticking and the bouncing regime at 0.04 m/s. Particles with greater velocities but below 1 m/s bounce off the wall. For yet greater velocities, fragmentation occurs. We give analytical models for the coefficients of restitution and fragmentation strength consistent with the experimental data. Set in context, our data show that CO$_2$ ice and silicate dust resemble each other in the collisional behavior. Compared to water ice the sticking velocity is an order of magnitude smaller. One immediate consequence as example is that water ice particles mantled by CO$_2$ ice lose any "sticking advantage." In this case, preferential planetesimal growth attributed to the sticking properties of water ice will be limited to the region between the H$_2$O ice line and the CO$_2$ ice line.

description: Solid waste dumping is a serious problem in urban areas as most solid wastes are not dumped in the suitable areas. Similar situation is observed in Harar town. The objective of this study was, therefore, to select potential suitable sites for solid waste dumping for the city of Harar. The study involves multi criteria evaluation method of weighted linear combination using GIS as a practical instrument to evaluate the suitability of landfill in the city. For the purpose of making decisions in landfill site selection, a hierarchy structural was formed and different parameters have been identified, including Slope, distance from water body, developed areas, sensitive areas, and roads and land use land cover. Initially, the rating method was used to evaluate each criterion individually. Then, the relative importance of criteria to each other was determined by an analytic hierarchy process. Simple Additive Weighting method was applied to evaluate the overall suitability. The result showed that 16.7% of the study area is highly suitable, 20.5% is moderately suitable and 33.2% and 29.6% respectively were least suitable and unsuitable for the purpose. Five candidate sites were identified and with more field investigation, one best suitable site was selected.

description: In this work we have investigated the effect of the solvent during the processing of SrFe12O19 platelet-based permanent magnets by cold sintering process (CSP) plus a post-thermal treatment. Several organic solvents: glacial acetic acid, oleic acid and oleylamine have been analyzed, optimizing the CSP temperatures at 190-270 °C, under pressures of 375-670 MPa and 6-50 wt% of solvent. Modifications in the morphological and structural properties are identified depending on the solvent, which impacts on the magnetic response. Independently of the solvent, the mechanical integrity of ferrite magnets obtained by CSP is improved by a post-annealing at 1100 °C for 2 h, resulting in relative densities around 92 % with an average grain size of 1 μm and a fraction of SrFe12O19 phase > 91 %. Hc > 2.1 kOe and MS of 73 emu/g are obtained in the final sintered ceramic magnets, exhibiting the highest HC value of 2.8 kOe for the magnet sintered using glacial acetic acid.
The Sedentarization of Oromia Pastoralists: A Matter of Policy or Necessity?

description: Pastoralists and agro-pastoralists in Oromia occupy a large proportion of landmass although they lead unstable life in arid and semi-arid areas. A gradual conversion of pastoral households into agro-pastoralism is evident in many parts of the region where such conversion induces shifts in livestock production strategies and land use. Crop cultivation has relatively increased over the last few decades where some proponents of pastoralism labelled such a move as invasion of farming to the dry land areas characterized by fragile ecology and unstable rainfall conditions. While such changes seem to be evolutionary, some claims underline that state development policies and political interventions in extending formal systems of governance are behind them. This study was undertaken to identify socioeconomic and environmental factors related to pastoralists’ preference for sedentarization employing both quantitative and qualitative research methods. The research tools used in the study were questionnaire, focus group discussions, key informant interviews, and non-participatory observations. The major finding of the study is that pastoralists ongoing shift to sedentary way of life has been triggered by the dynamic changes that have been occurring in pastoral areas over years and has less to do with the state development policies and political interventions. The implication of this is that all concerned stakeholders ought to support and facilitate this evolutionary shift in all aspects in a manner that it benefits the subjects without disturbing the ecosystem.

description: We introduce a fast and accurate heuristic for adaptive tomography that addresses many of the limitations of prior methods. Previous approaches were either too computationally intensive or tailored to handle special cases such as single qubits or pure states. By contrast, our approach combines the efficiency of online optimization with generally applicable and well-motivated data-processing techniques. We numerically demonstrate these advantages in several scenarios including mixed states, higher-dimensional systems, and restricted measurements.

In dieser Arbeit werden alle Gefäßpflanzen, die auf der Insel Lime Cay gefunden worden sind, aufgezählt und beschrieben. Lime Cay ist eine kleine Koralleninsel, also eine flache Insel, die vor der Küste Jamaikas liegt, unweit von Kingston. Sie ist Teil des ‚Palisadoes-Port Royal Cays’-Schutzgebietes. Diese winzige Insel hat eine reichhaltige Gefäßpflanzenflora von 46 Arten aus 30 Pflanzenfamilien, davon sind mit sieben Arten die Fabaceen am stärksten vertreten.Die vorliegende Untersuchung beruht auf Kollektionen und Daten vom Februar 2004, einschließlich älterer Angaben aus der Literatur und aus den Herbarien IJ, TUR und UCWI. Die auf Lime Cay gefundenen Arten sind in der Lage, sich selbst durch Luft- und Wassertransport anzusiedeln und sie tolerieren Salzboden und saline Atmosphäre oder brauchen sie sogar. Diese kleine Flora ist vielleicht eine Hilfe zur Bestimmung von Pflanzen ähnlicher kleiner Karibikinseln.
description: CHRISTENHUSZ, M.J.M. 2008: Florula of Lime Cay – an account of the vascular plants on a small Jamaican islet. Schlechtendalia 17: 1–25.In this article an account and descriptions of all vascular plants found on Lime Cay are given. Lime Cay is a small coral island, a ‘key’, which lies in front of the Jamaica coast, not far from Kingston, and is part of the Palisadoes-Port Royal Cays Protected Area. This tiny island has a rather diverse vascular flora of 46 species in 30 families. With seven species, the legumes (Fabaceae) are most diverse.This study is based on specimens and data collected in February 2004, and includes previous records from literature and from herbarium specimens in IJ, TUR and UCWI. The species found on Lime Cay are able to avail themselves of avevectent and aquavectent transportation, and can withstand or need a saline soil and atmosphere. This florula may be an aid to the identification of plants on similar Caribbean keys.

description: A comprehensive study, supported by systematic measurements and numerical computations, of the intrinsic limits of multi-GEM detectors when exposed to very high particle fluxes or operated at very large gains is presented. The observed variations of the gain, of the ion back-flow, and of the pulse height spectra are explained in terms of the effects of the spatial distribution of positive ions and their movement throughout the amplification structure. The intrinsic dynamic character of the processes involved imposes the use of a non-standard simulation tool for the interpretation of the measurements. Computations done with a Finite Element Analysis software reproduce the observed behaviour of the detector. The impact of this detailed description of the detector in extreme conditions is multiple: it clarifies some detector behaviours already observed, it helps in defining intrinsic limits of the GEM technology, and it suggests ways to extend them.

description: KRUMBIEGEL, A. 2008: Floristic information about the east bank of the Müritz (Müritz National Park). Schlechtendalia 17: 27–31. The area around Boek at the eastern bank of the Müritz was not or only partly accessible until 1990. This causes the lack of actual records (since 1980) of many even “trivial” species. The present survey contains many of such confirmed data as well as some records of new findings.
Method for determining the residual electron- and hole- densities about the neutrality point over the gate-controlled n $\leftrightarrow$ p transition in graphene

description: The Hall effect, and the diagonal resistance, which indicates a residual resistivity $ρ_{xx} \approx h/4e^{2}$, are experimentally examined over the p$\leftrightarrow$n transition about the nominal neutrality point in chemical vapor deposition (CVD) grown graphene. A distribution of neutrality potentials is invoked in conjunction with multi-carrier conduction to model the experimental observations. From the modeling, we extract the effective residual electron- and hole- densities around the nominal neutrality point. The results indicate mixed transport due to co-existing electrons and holes in large area zero-band gap CVD graphene devices, which indicates domain confined ambipolar currents broadly over the gate-induced n $\leftrightarrow$ p transition.

Improved nonlinear plasmonic slot waveguide: a full study

description: We present a full study of an improved nonlinear plasmonic slot waveguides (NPSWs) in which buffer linear dielectric layers are added between the Kerr type nonlinear dielectric core and the two semi-infinite metal regions. For TM polarized waves, the inclusion of these supplementary layers have two consequences. First, they reduced the overall losses. Secondly, they modify the types of solutions that propagate in the NPSWs adding new profiles enlarging the possibilities offered by these nonlinear waveguides. Our structure also provides longer propagation length due to the decrease of the losses compared to the simple nonlinear slot waveguide and exhibits, for well-chosen refractive index or thickness of the buffer layer, a spatial transition of its main modes that can be controlled by the power. We provide a full phase diagram of the TM wave operating regimes of these improved NPSWs. The stability of the main TM modes is then demonstrated numerically using the FDTD. We also demonstrate the existence of TE waves for both linear and nonlinear cases (for some configurations) in which the maximum intensity is located in the middle of the waveguide. This kind of structures could be fabricated and characterized experimentally due to the realistic parameters chosen to model them.
Rotational shear near the solar surface as a probe for subphotospheric magnetic fields
Creators: name: Kitchatinov, Leonid
Publisher: name: arXiv
Year: 2016
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Helioseismology revealed an increase in the rotation rate with depth just beneath the solar surface. The relative magnitude of the radial shear is almost constant with latitude. This rotational state can be interpreted as a consequence of two conditions characteristic of the near-surface convection: the smallness of convective turnover time in comparison with the rotation period and absence of a horizontal preferred direction of convection anisotropy. The latter condition is violated in the presence of a magnetic field. This raises the question of whether the subphotospheric fields can be probed with measurements of near-surface rotational shear. The shear is shown to be weakly sensitive to magnetic fields but can serve as a probe for sufficiently strong fields of the order of one kilogauss. It is suggested that the radial differential rotation in extended convective envelopes of red giants is of the same origin as the near-surface rotational shear of the Sun.

description: We report two new classes of face-centered photonic square lattices with flat bands which we call the Lieb-I and the Lieb-II lattices. There are 5 and 7 sites in the corresponding unit cells of the simplest Lieb-I and Lieb-II lattices, respectively. The number of flat bands $m$ in the new Lieb lattices is related to the number of sites $N$ in the unit cell by $m=(N-1)/2$. Physical properties of the lattices with even and odd number of flat bands are different. We also consider localization of light in such Lieb lattices. If the input beam excites the flat-band mode, it will not diffract during propagation, owing to the strong localization in the flat-band mode. For the Lieb-II lattice, we also find that the beam will oscillate and still not diffract during propagation, because of the intrinsic oscillating properties of certain flat-band modes. The period of oscillation is determined by the energy difference between the two flat bands. This study provides a new platform for the investigation of flat-band modes.

description: We investigate a model of hard-core bosons with correlated hopping on the honeycomb lattice in an external magnetic field by means of a coupled-wire approach. It has been numerically shown that this model exhibits at half filling the bosonic integer quantum Hall (BIQH) state, which is a symmetry-protected topological phase protected by the $U(1)$ particle conservation [Y.-C. He et al., Phys. Rev. Lett. 115, 116803 (2015)]. By combining the bosonization approach and a coupled-wire construction, we analytically confirm this finding and show that it even holds in the strongly anisotropic (quasi-one-dimensional) limit. We discuss the stability of the BIQH phase against tunneling that break the separate particle conservations on different sublattices down to a global particle conservation. We further argue that a phase transition between two different BIQH phases is in a deconfined quantum critical point described by two copies of the (2+1)-dimensional $O(4)$ nonlinear sigma model with the topological $θ$ term at $θ=π$. Finally we predict a possible fractional quantum Hall state, the Halperin (221) state, at 1/6 filling.
