The Promises and Perils of Urban Redevelopment for Land Value Capture in Addis Ababa: the Case of Casa Inchis Redevelopment Project
Creators: name: Yirgalem, Frew
Publisher: name: Ethiopian  Journal of Social Sciences
Year: 2018

description: n 2002, the city government of Addis Ababa launched the Casa Inchis redevelopment project with the dual objectives of eradicating slum and bringing land into profitable use by accommodating commercial and mixed land uses. This paper assessed the extent to which the government managed to capture land value increment by redeveloping Casa Inchis, and examined whether or not the value captured is recycled to recover intervention cost and/or to benefit displaced households. Empirical data was collected during a field visit to the project site. Data sources also include the Casa Inchis LDP, land transactions, compensation and relocation reports, satellite and ground images, urban land policy documents, and interview with officials and experts. It was found out that the redevelopment in Casa Inchis resulted in about five fold increase in land value. Modifying density regulation, land use change and the government's investment in redevelopment were the driving forces for the land value increment. Evidences also suggest that the monetary benefit of the redevelopment was nearly twice that of its cost. Hence, the findings of this study suggest that the city government was successful in capturing part of the land value increment in Casa Inchis. Nevertheless, the study also revealed that the value capture endeavor had some gloomy aspects. First, the project was implemented at the expanses of displaced households. Only 32% of households were eligible for compensation; the majority had to move away for nothing despite residing in Casa Inchis for over 25 years. Second, by transfering the land free of lease payment, the project resulted in the loss of revenue (estimated to be close to USD 20 million) which could have been collected from lease payment to recover intervention cost and benefit displaced households. Third, though the LDP stipulated land sharing and mobilizing land value to relocate households on-site, the project implementers opted for off-site relocation. Along with the lack of political accountability and commitment, the emphasis on revenue generation and city beautification over improving the living condition of slum dwellers seem to be the underlying factors. Fourth, the process was also found to be marred with lack of transparency in plot transfer, preferential treatment of some households over others, and absence of any meaningful obligations on developers despite the government had the legal leverage for doing so. This study emphasizes the imperative for policy makers to appreciate the benefits and properly deal with the challenge of designing a 'pro-poor redevelopment' and value capture strategy that not only brings efficiency in land use and eradicates slum but also improves the living conditions of slum-dwellers.

description: We consider fluctuations of the energy on a mesoscopic island coupled to two leads. We use the Keldysh effective action formalism to derive the Langevin equation for the energy of the island in a very general setting and show how the Langevin equation for the case of uncorrelated tunneling events is derived from a more general one. As an application of the theory, we consider a superconducting island coupled to two normal metal leads and calculate the statistics of the temperature (in the quasiequilibrium case) and the number of quasiparticle excitations on the island.

The Pitfalls of Ethiopia’s Ethnic-Based Federal System: Towards a Democratic Federalism
Creators: name: Bezabih, Ayalew Zeleke
Publisher: name: Ethiopian  Journal of Social Sciences
Year: 2018

description: The toppling of the Derg, which ruled the country for seventeen years, by the EPRDF-led forces in 1991marked another important turning point in Ethiopia’s socio-economic and political history. A great majority of the literature on Ethiopia’s federal system reveals that federalism in its ethnic model has emerged as one of the highly contested topics causing heated debate among scholars of the field and various political forces. This article attempts to critically examine the deficits of the Ethiopian federal system through a careful and thorough review of the existing literature on the subject. Relevant information for the study was drawn from different books, journal articles, theses, dissertations, governmental reports and legal documents. The paper indicates that Ethiopia’s ethnic federal model deviates from the basic and common principles of federalism in many respects such as in its philosophy of legitimacy, division of authority, balance of unity and diversity, democracy and institutional frameworks. The paper argues that there is an urgent need for developing a roadmap which redresses these shortcomings in the system, and paves the way for the institutionalization and maturity of a genuine democratic federalism in Ethiopia.

description: Women empowerment issues perceived nationally or locally are being addressed by both state and non-state agencies. Beside the government intervention, NGOs are implementing various types of Women Empowerment Programs. In this paper an attempt has been made to shed light on the effectiveness of NGO’s functions on women’ s empowerment in Bahir Dar town. A cross-sectional survey research design was employed to address the research objectives . The respondents were selected using simple random sampling technique from three NGOs working on women’s empowerment in Bahir Dar city; namely, Care Ethiopia, Mums for Mums and Catholic Women’s Training Center. This study measures women’s empowerment at two levels: individual and collective (community) empowerment on four dimensions; (economical, socio-cultural, familial/interpersonal and psychological dimensions). Findings indicate that NGOs were effective on women’s empowerment programs on saving and credit service functions with (M=129.80, SD=12.56), followed by social development and vocational training services (M=127.11, SD=11.39). The study emphasizes the need for NGOs to organize and integrate their activities to effectively address the problem of women in Bahir Dar city.

description: The exquisite photometric precision of the Kepler space telescope now puts the detection of extrasolar moons at the horizon. Here, we firstly review observational and analytical techniques that have recently been proposed to find exomoons. Secondly, we discuss the prospects of characterizing potentially habitable extrasolar satellites. With moons being much more numerous than planets in the solar system and with most exoplanets found in the stellar habitable zone being gas giants, habitable moons could be as abundant as habitable planets. However, satellites orbiting planets in the habitable zones of cool stars will encounter strong tidal heating and likely appear as hot moons.

Households’ Perceptions and Adaptation Techniques to Climate Variability in DroughtProne Areas of the Amhara Region, Ethiopia
Creators: name: Bazezew, Arega
Publisher: name: Ethiopian  Journal of Social Sciences
Year: 2018

description: This study examines households’ perceptions to climate variability and responses taken for food security in drought-prone areas of the Amhara Region, taking Lay Gayint district as a study site. Questionnaire survey, key informants interview and focus group discussions were employed to collect the primary data. A total of 201 households participated in the questionnaire survey. The study revealed that the high inter-annual and inter-seasonal rainfall variability were the primary cause for the decline of crop production and households’ vulnerability to food security. This could be the reason that the majority of the households faced food deficit for several months in the year and the gap is filled by the government safety nets and other income generating activities. In all agro-ecological zones, the majority of the households perceived that annual rainfall is inadequate to support the growing of crops and grazing of animals. The study households also predicted that recurrent droughts would occur in the future mainly due to land degradation, high population pressure and erratic rainfall. The study found that planting trees for the market, livestock fattening, and stocking seed reserves to be vital adaptive strategies employed by the majority of the better-off households while, whereas the poor and vulnerable households utilized short-term responses to meet the shortfall of consumption needs. The study recommends that households’ vulnerability to climate change and food insecurity could be minimized through appropriate and targeted risk reduction and management interventions that are well integrated to households’ adaptive strategies related to climate change.

Causes of Transnational Marriage with a Home-based Spouse: Case Study from Gondare/ Ethiopians in the Diaspora
Creators: name: Abeje, Aschalew

Year: 2018

description: This study analyzes the reasons why Gondare (natives of Gondar district, northwest Ethiopia) migrants choose to marry a home-based spouse. Data are collected from migrants coming home for this aim and from families through interview and questionnaire. Document analysis is used to supplement them. Although women involve considerably, findings show that men are the principal actors in such deals. This study approaches multiple experiences as intersecting mechanisms and found decisions for a marriage at home as multi-causal. It reveals that differential gender orders at the two ends set the precedence for this preference. It also shows time constraint, family pressure, desire for acknowledged marriage, and political contexts at home as important factors shaping migrants’ decisions for a home-based spouse.

description: We report an observation of a small scale flux-tube that undergoes kinking and triggers the macrospicule and a jet on November 11, 2010 in the north polar corona. The small-scale flux-tube emerged well before the triggering of macrospicule and as the time progresses the two opposite halves of this omega shaped flux-tube bent transversely and approached towards each other. After $\sim$ 2 minutes, the two approaching halves of the kinked flux-tube touch each-other and internal reconnection as well as energy release takes place at the adjoining location and a macrospicule was launched which goes upto a height of 12 Mm. Plasma starts moving horizontally as well as vertically upward along with the onset of macrospicule and thereafter converts into a large-scale jet which goes up to $\sim$ 40 Mm in the solar atmosphere with a projected speed of $\sim$ 95 km s$^{-1}$. We perform 2-D numerical simulation by considering the VAL-C initial atmospheric conditions to understand the physical scenario of the observed macrospicule and associated jet. The simulation results show that reconnection generated velocity pulse in the lower solar atmosphere steepens into slow shock and the cool plasma is driven behind it in form of macrospicule. The horizontal surface waves also appeared with the shock fronts at different heights, which most likely drove and spread the large-scale jet associated with the macrospicule.

Year: 2018

description: Rural youth outmigration from densely populated agricultural areas is a common phenomenon in Ethiopia. The purpose of this study is to assess the impacts of youth outmigration on the socioeconomic and demographic behavior of migrant-sending households using survey data and in-depth interviews. The findings revealed that remittances are considered important by the migrant-sending households to enhance asset formation, increase levels of income and consumption, improve debt repayment position, and augment family member’s education and medication expenses. The study further underscored the positive impacts of youth rural outmigration in improving human-environment relations through fertility reduction and easing population pressure, and mitigation of harmful traditional practices.

description: Empress Mentewab was one of the most influential female political figures that the country saw in its long history. Her beauty which is eulogized by some writers of the time latter helped her to control power especially during the time of Emperor IYASU ll. Her political grip, as we shall see, was not, however, a result of sheer beauty. She was, rather, a person who could put beauty and understanding together to control the reins of government for about half a century. Her political skill was revealed, among others, in the political marriages that she arranged with the most influential lords of the time who ruled the major political units of the country; viz, Tigray, Lasta and Begemder, and Gojjam.

description: HIV/AIDS has already become one of the greatest challenges to human life. Since its emergence more than two decades ago, HIV/AIDS has killed tens of millions of people around the globe, and the misery and suffering it caused is more evident in developing countries such as Ethiopia. The general objective of this study was therefore to assess the economic impact of HIV/AIDS on household’s livelihood in Gondar town. Mixed research design was employed for the study. The total sample for this study was164 households selected using census methods. Questionnaires, focus group discussions, key informants interview and direct observations were used to collect data. Multivariate analysis of variance (MANOVA) was employed to show the variations between categorical independent variable and continuous independent variables. The study revealed that there was strong relationship between household income and expenditures to basic needs before and after HIV infection. It was also noted that the majority of the households (70.3%) did not have access to the basic services such as housing, water and toilet. The survey result showed that saving (26.6%) and borrowing (20.3%) were the major coping strategies for the affected households. Creation of community awareness and the proper allocation of funds for the intended purpose could reduce the economic crises of the households due to HIV/AIDS infection. Besides, there is a need for political and financial commitment to prevent the disease, and toprovide treatment and care services to the community.

Ethiopia and Greece: The Early Connections
Creators: name: A. Fisher, Elizabeth
Publisher: name: Ethiopian  Journal of Social Sciences
Year: 2018

description: From literally the beginning of Greek literature, line 22 in Homer’s Odyssey, Ethiopia featured as a special place: where men were blameless and most reverent and the gods enjoyed feasts. Ethiopia was known as the source of the Nile River and a source for many exotic materials. Though ancient writers sometimes appear to have been unsure of the exact location of this far-off place, many of the ethnographic and geographic observations recorded by Greek and Latin authors about Ethiopia are detailed and accurate. The earliest connections of Greece and Ethiopia date to the Bronze Age. The first use of the word “Ethiopia” is found on clay tablets from Greece, dating to 1200 BC. Wall-paintings dating 400 years earlier than the tablets may record Greek participation in an expedition to the Land of Punt in the Horn of Africa. These early indications of contact between Greece and Ethiopia should point the way for new archaeological research.

description: During therapeutic treatment with heavy ions like carbon, the beam undergoes nuclear fragmentation and secondary light charged particles, in particular protons and alpha particles, are produced. To estimate the dose deposited into the tumors and the surrounding healthy tissues, an accurate prediction on the fluences of these secondary fragments is necessary. Nowadays, a very limited set of double di ffential carbon fragmentation cross sections are being measured in the energy range used in hadrontherapy (40 to 400 MeV/u). Therefore, new measurements are performed to determine the double di ffential cross section of carbon on di erent thin targets. This work describes the experimental results of an experiment performed on May 2011 at GANIL. The double di ffential cross sections and the angular distributions of secondary fragments produced in the 12C fragmentation at 95 MeV/u on thin targets (C, CH2, Al, Al2O3, Ti and PMMA) have been measured. The experimental setup will be precisely described, the systematic error study will be explained and all the experimental data will be presented.

Publisher: name: Ethiopian  Journal of Social Sciences
Year: 2018

description: leqa Tayye Gebre Maryam was one of the few Ethiopian intellectuals of the early twentieth century. His long stay with the Swedish Evangelical missionaries at Menkullu near Massawa and his sojourn in Germany for several years seemed to have prompted him to critically look into the teachings of the Ethiopian Orthodox Church. But he soon became a victim of religious intolerance. He was accused of being Tsere Maryam (enemy of Mary) and thrown to jail. Although little is known about Aleqa Tayye’s reformist ideas, he had urged emperor Menilek to issue a national currency, set up a printing press, open a modern school, and ban the use of scornful language against craftsmen. Eventhough most of his works remained unpublished, Aleqa Tayye was also a prolific writer. After his death, some of his manuscripts were acquired by Blattengeta Hiruy Wolde Sellase who published them as his own works. Using the scanty available literature, this paper attempts to investigate the life of Aleqa Taye Gebre Maryam.

description: The discovery of two-dimensional electron gases (2DEGs) at the heterointerface between two insulating perovskite-type oxides, such as LaAlO3 and SrTiO3, provides opportunities for a new generation of all-oxide electronic and photonic devices. However, significant improvement of the interfacial electron mobility beyond the current value of approximately 1,000 cm2V-1s-1 (at low temperatures), remains a key challenge for fundamental as well as applied research of complex oxides. Here, we present a new type of 2DEG created at the heterointerface between SrTiO3 and a spinel γ-Al2O3 epitaxial film with excellent quality and compatible oxygen ions sublattices. This spinel/perovskite oxide heterointerface exhibits electron mobilities more than one order of magnitude higher than those of perovskite/perovskite oxide interfaces, and demonstrates unambiguous two-dimensional conduction character as revealed by the observation of quantum magnetoresistance oscillations. Furthermore, we find that the spinel/perovskite 2DEG results from interface-stabilized oxygen vacancies and is confined within a layer of 0.9 nm in proximity to the heterointerface. Our findings pave the way for studies of mesoscopic physics with complex oxides and design of high-mobility all-oxide electronic devices.

Which Kind of Land Reform for Ethiopia: The Debate Preceding the 1975 Land Proclamation
Creators: name: Abebe, Mengistu
Publisher: name: Ethiopian  Journal of Social Sciences
Year: 2018

description: Sustained agricultural development depends on the proper management of the land and the people, and their relationships-i.e. the system of land tenure. The feudal system of Ethiopia was, however, believed to be a bottleneck for the utilization of the country’s agricultural potential. Then, the students and the progressive intelligentsia played the vanguard role in the political agitation for land reform for more than a decade. The imperial government was unable to meet the demands of the popular movement that ultimately brought the regime to its demise. On September 2, 1974 the Provisional Military Administrative Council (PMAC) commonly called ‘Derg’ controlled the government. Then, the issue of land reform became the subject of much discussion and controversy within the PMAC, student groups and radical intelligentsia and the public at large. The debate was conducted on two different levels, formally in the government institutions and in the official newspapers, and informally in the underground publications and in public gatherings. It took about six months of discussion and elaboration for the PMAC until its radical wing finally proclaimed the March 1975 land reform. The foregoing debate revealed the degree of polarization between the reformists and the revolutionists. The major questions in the struggle between the two poles were centered around the objective of the land reform, the issue of land ownership and of ceilings, and the method of its implementation.

description: The objective of this study is to evaluate the land use and land cover dynamics over 41 years (1973 to 2013) and to identify the major causes of changes in land use and land cover in the Mizewa watershed. The study used an integration of Remote Sensing (RS) and Geographic Information System (GIS) approach for analyzing the direction, magnitude, and spatial pattern of land use and land cover change in the study watershed. Results of this study showed that there were changes in land use and land cover patterns. Cultivated lands increased by 16.42% and 8.46% between 1973 to 1985 and 1986 to 1999 respectively. Furthermore, from 2000 to 2013, there were 1040.214, 984.028 and 111.02 hectares of settlement and plantation, bush lands and grasslands had been changed to cultivated land. The expansion of cultivated lands between 1973 and 2013 in the watershed could be directly related to rapid population growth and the clearing of bush lands and grass lands for such increasing agricultural land demand. On the contrary, the size of shrub or bush lands and grass lands coverage had decreased from 1973 to 1985 with -17.18% and -39.79% with an annual rate of change of -1.32% and -3.07% respectively. In addition, settlement and plantation increased from 1985 to 1999 with a rate of 6.18% per year. However, grass lands and bush lands decreased from 1985 to 1999 with annual rate of change -0.78 and -2.11% respectively. The change was induced by the transformation of bush lands and grass lands to cultivated lands. The massive reduction of shrub or bush lands particularly between 1973 and 1985 occurred due to lack of administration especially during the transition period and land redistribution as well as drought. Shortage of land has forced farmers to cultivate steep slopes and shallow soils that are vulnerable to degradation, and to increasingly rely on selling firewood and charcoal for supplementary income which has also contributed to the extensive destruction of the woody biomass and shrub lands. The cumulative effect of these had resulted in environmental degradation. Hence, it is recommended that there should be appropriate land use planning that identifies the proper land for specific purpose so that the marginal lands will not be put into agricultural use.

description: A model for the rival mechanisms of hysteresis in graphene channel resistivity on a substrate of different nature dependence on a gate voltage - a direct one (caused by adsorbates with dipole moment on surface and interface) and an inverse one (caused by capture of free carriers from graphene onto localized states on graphene-substrate interface) is proposed. Possible discrimination of these two channels by variation of the gate voltage sweep rate is discussed. Our theory predictions are in good correlation with experimental data, available in literature.

description: We studied the charge-orbital ordering in the superlattice of charge-ordered insulating Pr$_{0.5}$Ca$_{0.5}$MnO$_3$ and ferromagnetic metallic La$_{0.5}$Sr$_{0.5}$MnO$_3$ by resonant soft x-ray diffraction. A temperature-dependent incommensurability is found in the orbital order. In addition, a large hysteresis is observed that is caused by phase competition between insulating charge ordered and metallic ferromagnetic states. No magnetic phase transitions are observed in contrast to bulk, confirming the unique character of the superlattice. The deviation from the commensurate orbital order can be directly related to the decrease of ordered-layer thickness that leads to a decoupling of the orbital-ordered planes along the c axis.

title: An investigation of the influence of a decision support system on simulated ice management performance
Creators: name: Soper, Jonathan
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: As automation becomes increasingly widespread in the marine industry, it is important that the efficacy of automated systems be appropriately gauged and measured. In this research, an experimental method was applied to test a decision support system (DSS) using inexperienced participants. These participants are provided with basic habituation but otherwise must depend on the DSS to provide strategic advice. They are then tasked with using their vessel to clear pack ice from the lifeboat launch zone of an offshore structure, using the DSS for strategic assistance. The experimental simulator has been used in other studies to gauge the effects of experience and training on ice management performance, which allows for a comprehensive comparison to be made across several different groups. The DSS contains expert knowledge and acts as a digital coach for the inexperienced participants in this study. It provides advice through video replays and text-based advice that was customized to their current approach when assistance is requested. The participants tended to adopt the expert strategies suggested by the DSS, but failed to deliver statistically significant improvements. This can be in part attributed to their lack of ship handling experience. Qualitative analysis from exit interviews also provided a good basis to guide improvements to the DSS. Ultimately, the experiment provides insights into the strengths and weaknesses of this DSS and describes an effective experimental method for evaluating this technology.

description: In this paper, we analyze the problem of constructing a surface pencil from a given spacelike (timelike) line of curvature. By using the Frenet frame of the given curve in Minkowski 3-space, we express the surface pencil as a linear combination of this frame and derive the necessary and sufficient conditions for the coefficients to satisfy the line of curvature requirement. To illustrate the method some examples showing members of the surface pencil with their line of curvature are given.

Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection

description: We present high-resolution (R~15000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already been found. These spectra are of high-quality (S/N > 300) for PN Tc 1, which permits us to search for the expected electronic transitions of neutral C60 and diffuse interstellar bands (DIBs). Surprisingly, we report the non-detection of the most intense optical bands of C60 in Tc 1, although this could be explained by the low C60 column density estimated from the C60 infrared bands if the C60 emission peaks far away from the central star. The strongest and most common DIBs in both fullerene PNe are normal for their reddening. Interestingly, the very broad 4428 A DIB and the weaker 6309 A DIB are found to be unusually intense in Tc 1. We also report the detection of a new broad (FWHM~5 A) unidentified band at ~6525 A. We propose that the 4428 A DIB (probably also the 6309 A DIB and the new 6525 A band) may be related to the presence of larger fullerenes (e.g., C80, C240, C320, and C540) and buckyonions (multishell fullerenes such as C60@C240 and C60@C240@C540) in the circumstellar envelope of Tc 1.

description: We model the present-day number and characteristics of Ultra-compact X-ray binaries (UCXBs) in the Galactic Bulge. The main objective is to compare the results with the forthcoming data from the Galactic Bulge Survey (GBS) in order to learn about formation scenarios, notably core collapse supernova rate, common envelope evolution and dynamical interactions, as well as the binary initial mass function. We use a binary population synthesis code and detailed stellar evolutionary tracks, combined with observations of the 11 known UCXBs. We predict a few hundred faint UCXBs with periods of 20-40 minutes that would be detectable by the GBS.

description: The Fermi Large Area Telescope (LAT) discovered the time signature of a radio-silent pulsar coincident with RX J0007.0+7302, a plerion-like X-ray source at the centre of the CTA 1 supernova remnant. The inferred timing parameters of the gamma-ray pulsar PSR J0007+7303 (P=315.8 ms; dot{P}\sim3.6 10^{-13} s s^{-1}) point to a Vela-like neutron star, with an age comparable to that of CTA 1. The PSR J0007+7303 low distance (\sim 1.4 kpc), interstellar absorption (A_V\sim 1.6), and relatively high energy loss rate (dot{E} \sim4.5 10^{35} erg s^{-1}), make it a suitable candidate for an optical follow-up. Here, we present deep optical observations of PSR J0007+7303. The pulsar is not detected in the Gran Telescopio Canarias (GTC) images down to a limit of r'\sim 27.6 (3 sigma), the deepest ever obtained for this pulsar, while William Herschel Telescope (WHT) images yield a limit of V \sim 26.9. Our r'-band limit corresponds to an optical emission efficiency η_{opt}= L_{opt}/dot{E} < 9.4 10^{-8}. This limit is more constraining than those derived for other Vela-like pulsars, but is still above the measured optical efficiency of the Vela pulsar. We compared the optical upper limits with the extrapolation of the XMM-Newton X-ray spectrum and found that the optical emission is compatible with the extrapolation of the X-ray power-law component, at variance with what is observed, e.g. in the Vela pulsar.

Lattice Calculation of the $K_L$-$K_S$ mass difference

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We report progress on calculating the $K_L$-$K_S$ mass difference in lattice QCD. T he calculation is performed on a 2+1 flavor, domain wall fermion, $16^3\times 32$ en semble with a 421 MeV pion mass. We include only current-current operators and drop all disconnected and double penguin diagrams in the calculation. The calculation is made finite through the GIM mechanism by introducing a valence charm quark. The long distance effects are discussed separately for each of the two parity channels. Whil e we find a clear long distance contribution from the parity odd channel, the signal to noise ratio in the parity even channel is exponentially decreasing and the two-p ion state can be seen in only a subclass of amplitudes. We obtain the mass differenc e $ΔM_K$ in a range from $5.12(24)\times 10^{-12}$ to $9.31(66) \times 10^{-12}$ MeV for kaon masses between 563 and 839 MeV.
