Determinants of avocado commercialization among smallholder farmers in Shebediono Woreda, Sidama Zone SNNPRS of Ethiopia
No full textThis study describes the characteristics of household market participation in avocado production. It investigates the approach required to overcome determinants of market participation among smallholders of avocado farmers in Shebedino woreda, SNNPRS, Ethiopia. The primary sources of the data are farm household surveys, focus group discussions, and key informant interviews. Two hundred twenty-eight households were selected using a purposive sampling technique. The data obtained were evaluated using Double-hurdle econometric models. The results of the binary probit model revealed that in the decision to sell, land size, family size, distance from the nearest market center, market information, access to media, and the total amount of avocado produced played a significant role. The truncated regression model indicated that the age of the household head, family size, market information and the total amount of avocado produced significantly affected the level of commercialization. The result showed that enhancing the efficient utilization of the existing limited farmland, family size, access to market information, and the total amount of avocado produced had a higher value and was seen as a critical opportunity to improve the lower-income farm households. As a result, better market information, family planning, and new technology like improved verity are required to increase demand for avocado produce and income generation. Concerned bodies need to establish a market center for the farmers around their home, increasing the probability of avocado market participation. The findings of this study may help in the development of appropriate policy intervention mechanisms to promote smallholder avocado commercialization in Sidama Zone

No full textEffect of Fiscal Policy on Unemployment in Ethiopia
No full textOver the years unemployment has increased tremendously in Ethiopia. It is a social and economic problem that has eaten deep into the Ethiopian economy. The main objective of this study was to examine the short term and long-term effects of Government spending and Tax revenue on unemployment in Ethiopia. Annual time-series data for the period of 1990-2021 were employed. The ARDL approach to co integration is applied to investigate the long run and short-run determinants of unemployment. The results of unit root suggested that both variables in the model were stationary after first difference. The results from regression analysis revealed that Government expenditure has the negative impact on Unemployment of Ethiopia. Co-integration technique was employed to establish the relationship between Fiscal policy and Unemployment. The results of co-integration test using ARDL test showed that over the period of 1990-2021 their Fiscal policy and Unemployment a negative and statistically significant short-term relationship was found. Furthermore, pairwise Granger causality test as well applied in order to find out the directional causation between Tax rate and Unemployment rate. The result indicates unidirectional causality running from unemployment to Tax and government expenditure. The concerned body should increase government spending. Therefore, the author recommends the need to increase expenditure on in productive ventures that are labor intensive which would increase employment. Keywords: Fiscal policy, Unemployment, co-integration, Tax rate DOI: 10.7176/JESD/12-15-03 Publication date:August 31st 202
Africa's engagement with the Universal Periodic Review: commitment or capitulation?
No full textThe UPR presents a striking similarity to the state reporting procedure that has been established under African Charter on Human and Peoples� Rights (ACHPR). Not only are both procedures based on constructive dialogue as a tool, and seeking to enhance introspection and inspection of state�s human rights performances, they also aspire to gauge the degree of compliance with the whole gamut of rights and freedoms. Both procedures are invariably incumbent on all African states, now that the ACHPR has been unanimously ratified by all states of the Continent. The first twenty years of state reporting under the ACHPR saw a myriad of problems, hence dubbed a procedure that has faced implementation crises of dangerous proportions: non-reporting, poor quality reports, poor quality of state delegates, diplomatic rather than honest dialogue, lack of concluding observations and other problems plagued the system. Overall, as one author notes, the reporting procedure under the ACHPR has �tend[ed] to be descriptive, formalistic, legalistic and self-congratulatory, rather than reflective and focused on substance and practical realities, and problems encountered." It is instructive therefore to ask the reasons underlying all African states� almost uniform timely reporting under the UPR and the quality thereof. This paper set out to address the question of whether African states� regular submission of reports under the UPR, which report they failed to submit under the regional instrument, was inspired by capitulation or compliance. It seeks to compare the efficacy of the state reporting procedure under the ACHPR during its first twenty years and the first round of reports under the UPR in the light of the roles of the triple actors involved in the processes - the reporting states, the UN Human Rights Council and NGOs � and the resultant progresses that might have been made in the domestic implementation of the human rights norms being monitored

Thirty-five small and 25 large farms were randomly selected. Quantitative data was collected from sampled households/farms for six to seven consecutive months. Qualitative data was also collected to supplement the quantitative data. All crossbreed milking cows of the sample households were included for the study. The result of the study showed that small commercial farms disbursed 38% more cost than large commercial dairy farms. More than 80% of the variable costs went to feed in both small and large dairy farms. The result also revealed that large dairy farms earned 55% more annual revenue than small farms. The larger revenue share was from milk sale followed by calf sale for both large and small dairy farms. The gross margin of large dairy farms was higher than the small counterparts by more than three folds. The benefit-cost ratio was 1.43 and 2.24 for small and large dairy farms, respectively, implying that large dairy farms are more profitable than small dairy farms. The benefits from both small and large dairying indicated that dairying is a beneficial business. Shortage of land, lack of credit, lack of technical support, lack of adequate market outlet, inefficiency of AI services, abortion, high price of feed and medicine were identified as the main constraints of dairy farming. It is suggested that the need to establish feed processing machines, cull unproductive cows, empower dairy farmers and key service providers through training, promoting, complementary technology packages and market infrastructures.
Consideration of Inter-laminar Strain-energy Continuity in Composite Plate Analysis using Improved Higher-order Theory
No full textThe main goal of this paper is to suggest an improved higher-order refined theory for analysing perfectly bonded stacked composite laminates with the usual lamination configurations. The analysis incorporates continuous flexural and in-plane displacements at the interfaces. Furthermore, the transverse shear stress is continuous and constrained with the Lagrange-multiplier technique by introducing 14 new unknown variables that are expressed in terms of the interfacial strain energy, which is assuming to be continuous throughout the thickness of the laminate. To determine the newly introduced flexural and in-plane unknown variables, the total potential energy is minimised using variational calculus. The numerical results are compared with those from existing reliable published papers. In general, the proposed approach is sufficient for analysing laminate structures with the required accuracy.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Magnitude and associated factors of intraoperative cardiac complications among geriatric patients who undergo non-cardiac surgery at public hospitals in the southern region of Ethiopia: a multi-center cross-sectional study in 2022/2023
No full textBackgroundIntraoperative cardiac complications are a common cause of morbidity and mortality in non-cardiac surgery. The risk of these complications increased with the average age increasing from 65. In a resource-limited setting, including our study area, the magnitude and associated factors of intraoperative cardiac complications have not been adequately investigated. The aim of this study was to assess the magnitude and associated factors of intraoperative cardiac complications among geriatric patients undergoing non-cardiac surgery.MethodsAn institutional-based multi-center cross-sectional study was conducted on 304 geriatric patients at governmental hospitals in the southern region of Ethiopia, from 20 March 2022 to 25 August 2022. Data were collected by chart review and patient interviews. Epi Data version 4.6 and SPSS version 25 were used for analysis. The variables that had association (p < 0.25) were considered for multivariable logistic regression. A p value < 0.05 was considered significant for association.ResultThe overall prevalence of intraoperative cardiac complications was 24.3%. Preoperative ST-segment elevation adjusted odds ratio (AOR = 2.43, CI =2.06–3.67), history of hypertension (AOR = 3.42, CI =2.02–6.08), intraoperative hypoxia (AOR = 3.5, CI = 2.07–6.23), intraoperative hypotension (AOR = 6.2 9, CI =3.51–10.94), age > 85 years (AOR = 6.01, CI = 5.12–12.21), and anesthesia time > 3 h (AOR =2.27, CI = 2.0.2–18.25) were factors significantly associated with intraoperative cardiac complications.ConclusionThe magnitude of intraoperative cardiac complications was high among geriatric patients who had undergone non-cardiac surgery. The independent risk factors of intraoperative cardiac complications for this population included age > 85, ST-segment elevation, perioperative hypertension (stage 3 with regular treatment), duration of anesthesia >3 h, intraoperative hypoxia, and intraoperative hypotension. Holistic preoperative evaluation, optimization optimal and perioperative care for preventing perioperative risk factors listed above, and knowing all possible risk factors are suggested to reduce the occurrence of complications
Effective interventions in preventing gestational diabetes mellitus: A systematic review and meta-analysis
No full textBackground: Lifestyle choices, metformin, and dietary supplements may prevent GDM, but the effect of intervention characteristics has not been identified. This review evaluated intervention characteristics to inform the implementation of GDM prevention interventions. Methods: Ovid, MEDLINE/PubMed, and EMBASE databases were searched. The Template for Intervention Description and Replication (TIDieR) framework was used to examine intervention characteristics (who, what, when, where, and how). Subgroup analysis was performed by intervention characteristics. Results: 116 studies involving 40,940 participants are included. Group-based physical activity interventions (RR 0.66; 95% CI 0.46, 0.95) reduce the incidence of GDM compared with individual or mixed (individual and group) delivery format (subgroup p-value = 0.04). Physical activity interventions delivered at healthcare facilities reduce the risk of GDM (RR 0.59; 95% CI 0.49, 0.72) compared with home-based interventions (subgroup p-value = 0.03). No other intervention characteristics impact the effectiveness of all other interventions. Conclusions: Dietary, physical activity, diet plus physical activity, metformin, and myoinositol interventions reduce the incidence of GDM compared with control interventions. Group and healthcare facility-based physical activity interventions show better effectiveness in preventing GDM than individual and community-based interventions. Other intervention characteristics (e.g. utilization of e-health) don’t impact the effectiveness of lifestyle interventions, and thus, interventions may require consideration of the local context. © The Author(s) 2024
