Challenges of Retaining Skilled Employees, The Case of Eritrean Public Sector
No full textThis article uses the public sector in the sub-Saharan nation of Eritrea to illustrate how the problem of brain drain poses severe challenges to developing countries. Following its analysis of the views of 313 Eritrean public servants, the article comes to the conclusion that deteriorating economic conditions, lack of good governance and political instability are the major causes of the brain drain in developing countries. On that basis, the article suggests some policy implications as well as frontiers for possible future research

No full textThis article takes a cue from the ever-growing literature on governance and security issues in contemporary Africa. It postulates that elections, and the manner in which they are administered, are a major cause of political conflict in many of the continent’s 54 member countries. In addition to the unfavourable environment in which elections are generally conducted, election results are often discredited simply because the losing candidates opt to interpret technical irregularities experienced in election administration as acts of electoral fraud perpetrated by the victorious candidates, in connivance with the Election Management Bodies. This article uses evidence from the Republic of Zambia to illustrate that proper, effective and efficient institutional arrangements can promote and enhance the ethical and professional administration of national elections, and thereby reduce the high incidences of post-election conflict in Africa. From this perspective, the article presents seven such institutional arrangements

Strategies for Electrical Network Expansion
No full textThe main focus of the transmission expansion planning is to find the optimal structure and least cost transmission investment alternatives of the forecasted load and generation configuration. In this paper, transmission investment methodology which focuses on alleviation of transmission line congestions is proposed. The proposed methodology is based on DC power flow under constrained Lagrangian multiplier and the locational marginal price. Within this framework constraints and variables associated with the derivation of Lagrangian multiplier and the locational marginal prices are included in the formulated transmission expansion planning problem. This expansion problem which optimize the total investment and operation cost is modeled using a single-stage and multi-stage decision framework. In the single-stage transmission expansion planning framework a single load/ generation configuration is considered and the location, type and number of extra transmission lines of the optimal network configuration are determined. In the multi-stage model, multiple dispatch in the demand and wind power generation is integrated using a number of scenarios and the optimal expansion plan which fulfills the operating condition of all scenarios is determined through a three phase selection mechanism. For illustration purpose the resulting mixed-integer nonlinear programming problem is applied on the New England 39 bus test power system. Both proposed models are implemented in AIMMS software and solved using the outer approximation algorithm provided with the optimization tool.Power systemsElectrical Power EngineeringElectrical Engineering, Mathematics and Computer Scienc
Factors affecting college students’ satisfaction with major curriculum: evidence from nine years of data”, International journal of humanities and social science
No full textAbstract This study assesses the extent to which eleven academically related factors affect the overall satisfaction with major curriculum at a midsized public University. Keywords: College students; satisfaction; curriculum; performance. Introduction Satisfaction is a well researched topic in both academic and non-academic (workplace) settings. In academic settings, students' satisfaction data helps colleges and universities make their curriculum more responsive to the needs of a changing marketplac
TAX EVASION AND CURRENCY RATIO: PANEL EVIDENCE FROM DEVELOPING COUNTRIES
No full textWe examine the link between tax evasion and the currency ratio for non-OECD countries for the period 1996-2013. Unlike previous studies, we use non-parametric methods of estimation because economic theory doesn’t prescribe a specific functional form for the relationship between currency ratio and its determinants. We find that higher tax rate and lower enforcement strength leads to a higher tax evasion and higher currency ratio. Furthermore, we find that the level of development, the rate of interest, the rate of inflation, and the degree of urbanization across countries tend to explain currency ratio. The study highlights a new link through which fiscal policy can have an effect on the composition of monetary aggregates and hence monetary policy

Staffing System Management: Evidences from Singapore
No full textThis paper uses Singapore as a case study to illustrate how staffing policies and practices affect the quality of the workforce which ultimately influence performance at employee and organization level. It reveals that Singapore public service has been able to put in place most of the ‘critical factors’ for an effective staffing system management. The presence of those critical factors have played an important role in making Singapore to be one of the most effective public services in the world. Finally, it forwards theoretical and practical implications of the study and future research direction.</jats:p
Immunohistochemistry-derived subtypes of breast cancer distribution in four regions of Ethiopia
No full textPurpose: Different biological characteristics, therapeutic responses, and diseasespecific
outcomes are associated with different molecular subtypes of breast
cancer (BC). Although there have been different studies on BC in the Ethiopian
capital city of Addis Ababa, there have been few studies in other parts of the
nation, and none have evaluated biological characteristics in other locations in
the context of the extensive ethnic and genetic diversity found in Ethiopia. This
study was carried out to evaluate the distribution of immunohistochemistry (IHC)
subtypes of BCs throughout four Ethiopian regions.
Methods: A total of 227 formalin-fixed paraffin-embedded (FFPE) tissue blocks
were collected from tertiary hospitals in four Ethiopian regions between 2015
and 2021. The IHC staining was performed for subtyping, ER, PR, HER2, and Ki-67
proliferation markers.

Results: The mean age at diagnosis was 43.9 years. The percentage of ER and
PR-negative tumors were 48.3% and 53.2%, respectively. The IHC subtypes
showed the following distribution: 33.1% triple-negative breast cancer (TNBC),
27.6% luminal B, 25.2% luminal A, and 14.1% HER2 enriched. In multiple logistic
regression analysis, grade III and HER2 positivity were associated with larger
tumor size, and also originating from Jimma compared to Mekele.
Conclusion: Patients with ER-negative, PR-negative, and TNBC were found in
48.3%, 53.2%, and 33.1% of cases, respectively, showing that half the patients
could potentially benefit from endocrine treatment. A considerably high
prevalence of TNBC was reported in our study, demanding additional research
that includes genetic predisposition factors. Additionally, aggressive tumors were
found in a high percentage of younger age groups, which must be considered
when planning personalized treatment strategies
