Participation of the Ethiopian Police Contingent in the United Nations Peace Operations: Focus on the Role and Challenges

This research article delved the role and challenges of the Ethiopian police contingent in the United Nations peace operations. To this end, the author used socio-legal research method. Both primary and secondary data collections tools were employed. Key informant interview based on the mission experience were used to collect primary data. Secondary data critically reviewed relevant normative frameworks, standards, official reports, websites and other materials. The finding indicated that the Ethiopian police contingents are performing policing roles including crime prevention; strengthen administration and capacity of local police, restructure and reform of the host states police. Nevertheless, Ethiopia’s participation remains very low and even nonexistent in most of the peace operations. The finding also indicated that lack of normative and institutional arrangements are among the major challenges of the police contingent. This in particular includes lack of clear selection guideline of the police for mission, pre-deployment training deficiencies to the police candidates on mission language, driving skill and mission area courses and lack of well-established training centers. This in turn stalled the Ethiopian police not to significantly respond to the call for UNPOL peace operations. Hence, Ethiopia’s normative frameworks and institutional arrangements should be in line with the UNPOL legal and policy frameworks. In this regard, lessons ought to be drawn from Rwanda, Ghana and Nigeria.

Search-Based Test Generation Targeting Non-Functional Quality Attributes of Android Apps

Mobile apps form a major proportion of the software marketplace and it is crucial to ensure that they meet both functional and nonfunctional quality thresholds. Automated test input generation can reduce the cost of the testing process. However, existing Android test generation approaches are focused on code coverage and cannot be customized to a tester\u27s diverse goals---in particular, quality attributes such as resource use.We propose a flexible multi-objective search-based test generation framework for interface testing of Android apps---STGFA-SMOG. This framework allows testers to target a variety of fitness functions, corresponding to different software quality attributes, code coverage, and other test case properties. We find that STGFA-SMOG outperforms random test generation in exposing potential quality issues and triggering crashes. Our study also offers insights on how different combinations of fitness functions can affect test generation for Android apps

Statistical Analysis of Relationships Between the Flow Regime and Riverine Ecosystems in the Umba River, Kenya

The Umba River basin is a transboundary river catchment shared between Kenya and Tanzania. It is endowed with unique and endemic plant and animal species in the coastal area. The river flow plays important role in maintaining the estuary that provides essential functions and services to the communities living in the area. To protect the freshwater biodiversity and to maintain the essential goods and services provided by the river, the components of the natural flow regime need to be investigated. The statistical analyses of relationships between the flow regime and the riverine ecosystems were evaluated using Ecosystem Functions Model (EFM). A natural flow regime composed of daily time series of water levels and discharges was analysed. Based on the flow regime and eco-hydro relationships, several statistical and seasonal results were computed for five ecosystem groups: aquatic animals, mangrove plants, riparian vegetation, macro invertebrates, and floodplain wetlands. The seasonal results presented the performance of the ecosystem groups in each water year of the flow period and the statistical results were computed as stages, flows, and percent exceedance for each relationship. The findings of this study can be considered as baseline information for comparing and identifying effective water resources development projects in the river.

A Simulation Based Performance Evaluation of Optical Ethernet Switch

With the advent of several new Cloud Radio Access Network (C-RAN) technologies, todays networking environment is dramatically altered and is experiencing a rapid transformation. One of the most important is Ethernet based C-RAN, in support of which many products such as optical Ethernet switches have recently appeared on the market. This paper presents the performance analysis of such switches with respect to Packet Loss Ratio (PLR), Latency and Packet Delay Variation (PDV). We employed the Simula based on Discrete Event Modelling on Simula (DEMOS), a context class for discrete event simulation to simulate a cut-through optical Ethernet switch under two types of traffics: High priority (HP) traffic and Low priority (LP) traffic. In this way, the paper evaluates the optical Ethernet switch performance quantitatively. The results obtained from the simulator showed that the high quality of service was reflected on HP traffic and the low quality of service in LP traffic. Hence, HP traffic can be used for transporting Radio over Ethernet (RoE) traffic while LP traffic can used for transporting time insensitive application. It is also found that HP traffic experiences a PDV equals to the duration of maximum sized LP traffic in Optical Ethernet switch.Comment: arXiv admin note: text overlap with arXiv:1911.0761

TMA-Based Beamforming For Next Generation Satellite Communication Applications

peer reviewedLow-Earth Orbit (LEO) satellite mega-constellations have attracted significant interest for their global network coverage and reduced latency with respect to their geostationary counterparts. LEO satellites are typically equipped with advanced antenna architectures, which allow spot-beam steering to specific areas within the field of view. With the aim to minimize onboard complexity, this paper studies the beam synthesis and steering using Time Modulated Arrays (TMA). By analyzing the properties of the on-off switching and their impact on the resulting beam footprint, this paper establishes the relationship between the pulse activation characteristics and the steering angle of the corresponding users in a downlink satellite-to- Earth transmission. The corresponding Signal-to-Noise Plus Interference Ratio (SINR) is derived and analyzed for multi-beam patterns with different inter-beam separations. We compare the performance of TMA-based LEO downlink transmission with conventional beamforming techniques, confirming the promising performance of TMA with reduced complexity. Finally, the TMA response is evaluated for practical channel estimation imperfections, demonstrating the degree of tolerance depending on the beam shape.8. Decent work and economic growt

The overlapping burden of the three leading causes of disability and death in sub-Saharan African children

Despite substantial declines since 2000, lower respiratory infections (LRIs), diarrhoeal diseases, and malaria remain among the leading causes of nonfatal and fatal disease burden for children under 5 years of age (under 5), primarily in sub-Saharan Africa (SSA). The spatial burden of each of these diseases has been estimated subnationally across SSA, yet no prior analyses have examined the pattern of their combined burden. Here we synthesise subnational estimates of the burden of LRIs, diarrhoea, and malaria in children under-5 from 2000 to 2017 for 43 sub-Saharan countries. Some units faced a relatively equal burden from each of the three diseases, while others had one or two dominant sources of unit-level burden, with no consistent pattern geographically across the entire subcontinent. Using a subnational counterfactual analysis, we show that nearly 300 million DALYs could have been averted since 2000 by raising all units to their national average. Our findings are directly relevant for decision-makers in determining which and targeting where the most appropriate interventions are for increasing child survival. © 2022, The Author(s).Funding text 1: This work was primarily supported by grant OPP1132415 from the Bill & Melinda Gates Foundation. ; Funding text 2: This study was funded by the Bill & Melinda Gates Foundation.

Global, regional, and national incidence of six major immune-mediated inflammatory diseases: findings from the global burden of disease study 2019

BACKGROUND: The causes for immune-mediated inflammatory diseases (IMIDs) are diverse and the incidence trends of IMIDs from specific causes are rarely studied. The study aims to investigate the pattern and trend of IMIDs from 1990 to 2019. METHODS: We collected detailed information on six major causes of IMIDs, including asthma, inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis, psoriasis, and atopic dermatitis, between 1990 and 2019, derived from the Global Burden of Disease study in 2019. The average annual percent change (AAPC) in number of incidents and age standardized incidence rate (ASR) on IMIDs, by sex, age, region, and causes, were calculated to quantify the temporal trends. FINDINGS: In 2019, rheumatoid arthritis, atopic dermatitis, asthma, multiple sclerosis, psoriasis, inflammatory bowel disease accounted 1.59%, 36.17%, 54.71%, 0.09%, 6.84%, 0.60% of overall new IMIDs cases, respectively. The ASR of IMIDs showed substantial regional and global variation with the highest in High SDI region, High-income North America, and United States of America. Throughout human lifespan, the age distribution of incident cases from six IMIDs was quite different. Globally, incident cases of IMIDs increased with an AAPC of 0.68 and the ASR decreased with an AAPC of −0.34 from 1990 to 2019. The incident cases increased across six IMIDs, the ASR of rheumatoid arthritis increased (0.21, 95% CI 0.18, 0.25), while the ASR of asthma (AAPC = −0.41), inflammatory bowel disease (AAPC = −0.72), multiple sclerosis (AAPC = −0.26), psoriasis (AAPC = −0.77), and atopic dermatitis (AAPC = −0.15) decreased. The ASR of overall and six individual IMID increased with SDI at regional and global level. Countries with higher ASR in 1990 experienced a more rapid decrease in ASR. INTERPRETATION: The incidence patterns of IMIDs varied considerably across the world. Innovative prevention and integrative management strategy are urgently needed to mitigate the increasing ASR of rheumatoid arthritis and upsurging new cases of other five IMIDs, respectively.
