Marital Dissolution and Associated Factors Among Primary Caregivers of Children With Neurodevelopment Disorders at Different Mental Health Service Centers In Addis Ababa, Ethiopia; A Cross-Sectional Quantitative Study.
(Addis Ababa Uinverstiy, 2026) Hiwotemedhin Aberra; Dr. Fikirte Girma; Dr. Biruh Alemayehu
Background: Neurodevelopmental disorders (NDDs) place significant
emotional, social, and economic burdens on caregivers, which may affect
marital stability. This study aimed to assess the prevalence of marital
dissolution among caregivers of children with NDDs and identify associated
socio-demographic, clinical, and psychosocial factors.
Methods: A cross-sectional study was conducted among 356 caregivers
using structured questionnaires. Data on socio-demographic characteristics,
child-related clinical variables, and psychosocial factors (including spousal
support, social support, stigma, and depression) were collected. Statistical
analysis was performed using SPSS version 26. Both bivariate and
multivariate logistic regression analyses were used to identify factors
associated with marital dissolution.
Results: The majority of participants were female (68.8%), married (86.5%),
and aged 18–39 years (53.4%). The overall prevalence of marital
dissolution was 9.3%. Many caregivers reported high spousal support
(43.3%%) despite poor social support (75.8%). Depression was common,
with 32.6% reporting minimal and 11.0% moderate depression. Higher
income was significantly associated with lower odds of marital dissolution,
with caregivers earning more than 20,000 birr being 94% less likely to
experience dissolution (AOR = 0.06; 95% CI: 0.007–0.55). Conversely,
comorbid seizure disorders were associated with increased odds of marital
dissolution (AOR = 5.41; 95% CI: 1.23–23.70). Other factors, including child
diagnosis, disease severity, depression, stigma, and social support, were
not significantly associated.
Conclusion: Marital dissolution among caregivers of children with NDDs
was relatively low and primarily influenced by socioeconomic factors,
particularly income. Higher income appears to be a strong protective factor
against marital dissolution, highlighting the importance of financial stability in
maintaining marital relationships. Despite high levels of caregiving burden
and poor social support, strong spousal support may play a protective role
in maintaining marital stability. Interventions focusing on economic
empowerment and strengthening intra-family support systems are
recommended.
The Pedagogical Aspect of Hisu Short and Long Interval Training Effects on Endurance Performance: Athletics Project Under 17 SinanaWoreda, Bale Zone, Oromia Region
(Addis Ababa University, 2016-08-01) Shiferaw Geremaw; Bezabih Wolde
The purpose of the study was to investigate pedagogical aspects of short and long interval training effects in athletics endurance performance of Hisu Athletics project. Data were collected through questionnaire, interview, practical execution and observation checklist. Purposively 50 respondents participated as the source of data thus, 40 Athletes, 4 coaches, 4 Sinanaworeda and 2 zone youth and sport officers were participated in the study. To analysis the collected data, both qualitative and quantitative methods such as frequency counts, percentage, means, standard deviation, and t-test were on use respectively. There was a significant improvement observed in estimated VO2 max from 12MRT, 20m Shuttle run and RHR, Weight and BMI, 30m sprinting power test experimental and control group pre-post training tests mean values score due to the twelve weeks physical fitness training had positive effects on participants’ endurance performance and also there is a problem of selecting athletes, the quality and pedagogical knowledge of coaches was not following scientific method of training, very low level of communication among stakeholders, a great constraint of facilities and equipment and shortage of encouragements for coaches and Athletes. To overcome these problems, the following recommendations have been forwarded: coaches should develop and learn how to prepare training level, the woreda and zone should find a way to upgrade the pedagogical knowledge of coaches, arranging trainings on how to prepare training level, all the sport leaders should work smoothly for the same goal, the woreda and zone youth and sport offices should work with difference stake holders to fulfill the constrains of resources.
An Assessment of Causes of Primary School Principals' Turnover in Arada Sub-city of Addis Ababa City Administration
(Addis Ababa University, 2012-06-01) Elias G-Yesus; Melaku Yimam
The main purpose of this study was to assess the causes of principals' turnover in government and public primary schools of Arada sub-city administration of Addis Ababa. Descriptive research method was employed in this study. Document analysis was employed to examine the rate of principals' turnover within the past five years (1999 E. C. - 2003 E. C.). A total of 78 respondents (28 on-duty primary school principals, 30 primary school ex-principals, 5 primary school cluster supervisors, 5 Sub-city educational officials and 10 other Woreda educational experts) from Arada sub-city administration, Addis Ababa were selected based on purposive sampling technique. Data collection for this study relied on self-report questionnaire, semi-structured interviews and document analysis. The questionnaires were prepared to collect data from on-duty principals, ex-principals and cluster supervisors about the problem under investigation. In addition, interviews were conducted with five sub-city Educational Office Officials and ten other Woreda Education Office Experts so as to crosscheck and enrich the data gathered through the questionnaire. Depending on the type of basic questions and the nature of the data, the frequency counts were converted into percentages as well as other computations such as mean scores were employed to analyze the data. Figures were also used to interpret and summarize the findings where necessary. SPSS (Version 16) was also employed to see the relationship between job dissatisfaction and principals' turnover. In addition, the information that was obtained through interview and document analysis was presented through narrative description to complete the data obtained by means of questionnaires. The findings of the study showed that: 1); among others,inadequate selection and promotion method, poor supervision and poor working condition are the administrative related causes of principals , turnover; 2) principals also quitted their job as a result of socio-economic related causes such as low pay and non-salary benefits in addition to administrative related causes; 3) the most serious potential source of principals 'turnover is found to be 'administrative related causes '; 4) principals' turnover has debilitative effects on students, on teachers and on the overall works of the school; 5)there is moderate negative relationship (1'=-.51, p=<0.01) between principals' turnover rate and job satisfaction; and 6) most of on-duty principals have plan to leave their current jobs for good.Based on the findings of this study, among others, some of the recommendations that were made are as follows: 1) educational officials at Sub-city and Woreda levels should make the administrative system transparent in which principals and teachers feel that they are part of the system; 2); experts and/or officials of Woreda and Sub-city Educational Offices shouldensure employee-consulted leadership style; 3) There should also be equity of promotional opportunity among employees of the same qualification and work experience; and 4) Woreda and Sub-city Educational Offices should establish effective grievance system at all levels.
Gefersa II Embankment Dam Hydraulic Failure and Remedial Measure
(Addis Ababa University, 2015-11) Kenbon Hordofa; Asie Kamal (PhD)
Dams are constructed regarding numerous purposes just like overflow command, course-plotting, water solutions, sport, power creation as well as irrigation and so forth. Soil dams have invariably been associated with seepage while they impound water it. Water looks for routes regarding the very least opposition from the dam and it is groundwork. Seepage could be the main problem also it travels from the dam product looked after transporting dam supplies. Seepage must be handled just to save the actual erosion regarding embankment or even their groundwork. Embankment dam is common in different other style of dams on account of numerous causes just like the employment of everyday development technologies method while using cheap fresh land product as well as subsurface supplies, absolutely no require of your distinct area condition and so forth. One of several important factors producing failing regarding embankment dam by simply seepage and hence seepage analysis regarding embankment dam is usually regarding larger significance. The slide is nothing but failure of volume of soil in downward direction. It is approximately caused by a slowly disintegration of the soil structures, by an increasing of pore- water pressure in a few more permeable layers, or by a shock that liquidizes of soil. The main factor for increasing of pore-water pressure the soil is failed in shear strength. The falling of shear strength may occur due to shock loads, rise in water content, varies in pore water pressure, weathering or any other cause. Most of general slope’s failure occurs during rainy season, as an including of moisture content causes both increased stresses and the loss of strength with the development of modern method of technique of stability investigation, a safe and cost of design of a slope have a thorough knowledge various methods for checking the failure of slopes and their restrictions.
Generation of Solar-Hydroelectric Energy to Control The Expansion of Lake Beseka, Ethiopia
(Addis Ababa University, 2016-10) Girma Amare; Geremew Sahilu (PhD)
The effect of climatic change and environmental degradation has caused the reduction of water level in Lakes, rivers and streams. For instance, Lake Chad in Chad, Abiyata, Hawassa, Ziway, and Haromaya are good examples. However, the water level of Lake Besaka has been rising for more than three decades. The surface area of the Lake has been expanding from 3 km2 to 46.6 km2 between 1973 and 2008 with corresponding to rise in Lake water Level (Goerner et al. 2009). The main cause for the increase in Lake water level and its surface area is the inflow of groundwater from the western part of the watershed. The average annual increment of Lake water level was 0.2 m and hence the Lake had risen by four meters between 1976 and 1997 (Goerner et al. 2009). The expansion and flooding effect of Lake Besaka has become the cause for the loss of 57 human lives, inundation of about 35km2 of grazing land, and displacement of 910 indigenous people. Methara sugar plantation has also been inundated and the company lost income from 161.55 ha of land (WWDSE 2011). The damages to the nearby railway line and highway caused a loss amounting to 2.6 million US$ (Tessema; Ayenew 2008). The expansion of Lake Besaka have still continued and severely affecting the life of the surrounding community and also becoming the contaminant to Awash River. To minimize the expansion rate of the Lake, Awash Basin Authority had installed six surface pumps of 1.7m3/sec capacity and had been pumping water from the Lake and released to Awash River (WWDSE 2011). However, the pumps were fully submerged due to high inflow and consequently the Lake continued to expand and submerge public infrastructures and becoming a contamination fear to Awash River. If Lake Besaka discharges to Awash River by itself without any control, the river is going to be contaminated forever (Wiliam Davison 2013). Despite, many researchers have conducted studies to mitigate the expansion Lake Besaka and proposed options to maintain the water quality of Awash River, there was no clear demarcation yet put that sustainably mitigate the crisis. However, this research aimed to answer how it is possible to sustainably Control the Expansion Lake Besaka, and maintain the water quality of Awash River through generating hydroelectric power. The research focused on solar energy to pump the Lake Water and generation of hydroelectric power while releasing the pumped water from upper reservoir to Awash River with safe blending ratios.
