    The study was conducted to assess the Ethiopia Industrial Parks Development Corporation service quality and its impact on investors’ satisfaction in Bole Lemi industrial park. The study was trying to analysis the office’s service quality on investor’s satisfaction with SERVQUAL. To conduct this study the researcher employed quantitative research approaches and census survey to collect the primary data. As a means to get data for the study questionnaires were distributed to administrative officials of the available enterprises found in Bole Lemi industrial park. Secondary data were collected from different published and unpublished documents such as relevant theoretical concepts, textbooks, and journals. The data were analyzed using SPSS version 20 using descriptive statistics (frequency, percentage) and inferential statistics like correlation and regression analysis. Finally, based on study findings the conclusion drawn and the researcher recommends the mentioned ideas for betterment and improvements of service quality of EIPDC.

    The Impact of Performance Appraisal on Employee Motivation in United Bank S.C
    (Addis Ababa University, 2017-05-26) Girma, Tigist; Chane, Abraraw (PhD)
    United bank has been implementing employee performance evaluation system whereby immediate supervisors are involved in the evaluation process. Though there were a few studies that have been conducted, they were not tried to see the issue in consideration of multiple performance variables. Therefore, the main objective of the study is to evaluate the relationship between performance appraisal and employees’ motivation in united bank S.C. in order to achieve the objectives, the focus of the study is on constructs of performance evaluation system including participate in objectives setting, quality of performance criteria, availability of pre-set goal, feedback and measuring performance based on evidence. The study employed a survey questionnaire and 331 were distributed of which 195, 95 and 41 are for clerical, non-clerical and managerial group respectively. Sample respondents are selected from nineteen branches and HO using stratified random sampling technique. Collected data through questionnaire were analyzed quantitatively using both descriptive and inferential statistics with the help of SPSS version 20. The result of the study indicated that performance appraisal has positive and significant relationship with employees’ motivation

    Phenotypic Characterization of Peripheral B cells in Mycobacterium tuberculosis infection and disease in Addis Ababa, Ethiopia
    (2018-06) Girma, Tigist; Tsegaye, Aster (MSc, PhD)
    Background: Mycobacterium tuberculosis (MTB) remains an unresolved threat resulting in great annual loss of life. The role of B cells during the protective immunity to MTB is still unclear. B cells have been described as effector cells in addition to their role as antibody producing cells during disease. Objective: to identify and characterize the frequency of peripheral B-cell subpopulations during active and latent tuberculosis. Methods: A total of 52 participants comprising 16 active untreated pulmonary TB (PTB) cases, 17 Latent Tuberculosis Infection (LTBI), and 19 Healthy Controls (HCs) were enrolled in the study. Peripheral blood samples were collected to do QuantiFERON (QFT) assay to diagnose LTBI and to isolate Peripheral Blood Mononuclear Cells (PBMC). PBMCs were stained with monoclonal antibodies. Expressions Cluster of differentiation (CD) markers was assessed on B cells subsets using multicolor flowcytometry. A difference in the frequency of B cell subsets among the groups was analyzed using the One-way Anova and Kruskal-Wallis tests was used for comparison between two groups. Data is presented as median (Interquartile range) and a P value of less than 0.05% was taken as a statistically significant difference. Results: Tissue-like memory B cells (CD19+CD27-CD21-); p = 0.0024 and class switched memory B cells (CD19+CD27+CD21+ IgM- IgD-); p = 0.0065 had significantly higher proportion in active PTB when compared to LTBI and HCs. On the contrary, resting memory B cells (CD19+CD27+CD21+); p <.0001, non-class switched memory B cells (CD19+CD27+CD21+ IgM+ IgD+); p = 0.0011, marginal zone B cells (MZCs) (CD19+CD27+CD21+IgM+IgD+CD23-); p = <0.0001 and regulatory B cells (Breg) (CD19+CD24hiCD38hiCD5+); p = 0.0043 had significantly lower proportion in active PTB group as compared to LTBI and HCs. There were no statistically significant difference observed in percentage of total B cells (CD19+); p = 02407, Naïve B cells (CD19+CD27-CD21+); p = 0.1156 and activated memory B cells (CD19+CD27+CD21-); p = 0.1134 among the three study groups. Conclusions: The findings of this study showed that B cells markers distinguish active untreated TB cases from LTBI, that indicate B cells phenotype is promising for clinical application as potential biomarker for TB disease and LTBI identification. A large scale longitudinal study is required to confirm and translate this finding into clinically applicable tests.
