    Evidence from Manufacturing Private Limited Companies in Addis Ababa, Ethiopia.
    (Addis Ababa University, 2010-11) Mohammed, Nuru; Ponnala, Venkati (PhD)
    Research studies on the effects of management of working capital policies on firms’ profitability in developing countries, especially in Ethiopia remained an ignored area of empirical research. Thus, this study examined the effect of working capital investment and financing policies on firms’ profitability by using audited financial statements of a sample of 11 manufacturing private limited companies in Tigray region, Ethiopia for the period of 2005 to 2009. The study used return on assets, return on equity and operating profit margin as dependent profitability variables. Accounts receivable period, inventory holding period and accounts payable period are used as independent working capital investment policy variables. Moreover, cash conversion cycle and current assets to total assets ratio are used as comprehensive measures of working capital investment policy. On the other hand, current liabilities to total assets ratio is used as measure of working capital financing policy. The two traditional measures, current ratio and quick ratio, are used as liquidity indicators. In addition, the study used firm size as measured by logarithm of sales, firm growth rate as measured by change in annual sales, financial leverage and annual GDP growth rate as control variables. Both correlation analysis and pooled panel data regression models of cross-sectional and time series data were used for analysis. The results show that longer accounts receivable and inventory holding periods are associated with lower profitability. There is also negative relationship between accounts payable period and profitability measures; however, except for operating profit margin this relationship is not statistically significant. The results also show that there exists significant negative relationship between cash conversion cycle and profitability measures of the sampled firms. No significant relationship between current assets to total assets ratio and profitability measures has been observed. On the other hand, findings show that a highly significant positive relationship between current liabilities to total assets ratio and profitability. Finally, negative relationships between liquidity and profitability measures have also been observed. Managers, therefore, can increase firms’ profitability by improving the efficiency of management of working capital investment and financing policies while, also keeping in view the trade-off between liquidity and profitability

    Feedback in the Efl Classroom: an Exploration of its Role in The Communica Non of Teacher Expect a Tions
    (Addis Ababa University, 2000-06) Mohammed, Nuru; Simon, Gebremedhin (PhD)
    lowe a great debt of heartfelt gratitude to so many people for their contributions that I cannot thank them all personally, but [ would particularly like to thank following. I am deeply indebted to Professor Keith Johnson, my supervisor on the Lancaster University side, for his insightful and critical comments on the drafts of my chapters. [ consider myself lucky and privileged to have done this work under his supervi sion. Special thanks, too, are due to Dr Gebremedhin Simon, my supervisor on the Addis Ababa University side, for his constructive comments and constant encouragement. I should like to thank all those teachers and their pupils who so kindly suffered my presence in the classroom and put up with the numerous questions that I had to ask during the interview and in the questionnaire. The project would have been impossible without The British Council who financed my study in the UK. Finally, I must thank my wife, Rahma Tirfu, tor her encouragement, and our children, Feti ya, Mubarak, and Aziza for bearing my absence.

    Feedback in the EFL Classroom: An Exploration of its Role in the Communication of Teacher Expectations.
    (2000-06) Mohammed, Nuru; Johnson, Keith(Prof.)
    This study examines teacher feedback practice in a foreign language classroom in relation to the proposition in the field of general education that teacher differential expectations for students' performance may be expressed in differential treatment toward students. More specifically, the purpose of this research is to explore whether ( I) the teacher provides different feedback to students whom he perceives as high and low achievers and, (2) differences can be attributed to differential teacher expectations. It also investigates whether (3) students perceive any difference in the ways the teacher works with high and low achievers as regards the provision of feedback and (4) the teacher sees his own treatment of high and low expectation students as being different. The analysis of observational data collected on a teacher's classroom feedback behaviour revealed great quantitative differences in the feedback received by hi gh and low expectation students on their successful and unsuccessful performances. Further analysis suggested that many of the differences are attributable to differences in performance among students although there were also several other differences (e.g. those that relate to the teacher's use of praise and failure to give feedback) that are interpretable as evidence of differential teacher treatment. In addition, the likelihood of the teacher's use of certain types of feedback (e. g. repetition and explanation of a correct answer) tended to vary with the expectation group membership of students. As regards the students' and the teacher's perceptions, both parties demonstrated a considerable degree of sensitivity to differential treatment of high and low achievers.

    (Addis Abeba Universty, 2014-03) Mohammed, Nuru; Kumie, Abera (PhD)
    Introduction: The completeness of medical records is an outstanding problem that affects the quality of health services in many hospitals of Ethiopia. Enhancing the completeness of patients records is inexpensive that can be implemented with the involvement of health workers. Objective: To improve the completeness of patient’s card admitted to Dalefage hospital. Design; Pre - post interventional study from January - August, 2013 GC uses inpatient medical record review form and focus group discussions. Setting; Dalefage district hospital, west Afar, Ethiopia. Participants: Medical director, matron and other clinical staffs. Implementation: The interventions implemented were avail inpatient medical record completeness format, facility based inpatient medical record completeness guideline and procedures were developed and onsite training was provided. The work plan progresses of implementation were monitored by check list. Main outcome measures: Availability of inpatient medical record completeness format, provision of onsite training, development of facility based guideline and procedure and enhancement of inpatient medical record completeness report. Evaluation: inpatient medical record format availability and completeness improved significantly from 0% to 100% and from 0% to 73.6% respectively. Lesson learned: our findings indicate that a well-organized inpatient medical record completeness enhancement can improve the quality of available inpatient information, helps to know our reporting status of inpatient medical record completeness which is crucial to plan improvement strategy and development of facility based guideline and procedure was required to accomplish sustainability. Lastly, onsite training was the best strategy for resource limited countries like Ethiopia to improve health care quality service delivery. Key words: medical record, availability, completeness, Dalefage hospital, Ethiopia.
