Blended learning requirements are increasing, in part because of the population explosion and policies pertaining to the democratization of education. Yet, thousands of students and faculty remain deficient in the use of blended learning to advance technology in developing countries, especially sub-Saharan Africa. This research employed a quantitative assessment design aimed at improving best available practices, processes, and performance in terms of the blended learning offered in a university setting. A six-point Likert-type questionnaire was used to gather data. Multiple statistical procedures were employed in the subsequent analysis—percentage, mean point values, chi-square, and ANOVA. Majority of the respondents to the questionnaire agreed that the teaching of MIS to students is effective and has a positive impact on their academic achievements. This groundbreaking research presents a realistic resource for the practical application of blended learning in university education in Nigeria, as well as a comprehensive view of the benefits and problems of the applicability of blended learning.

Retrospective Comparative Study

Complications of pregnancy remain a serious threat in Sub-Saharan Africa despite efforts to minimise maternal mortality due to pregnancy complications, and achieve the Millennium Development Goal 5. This is a retrospective study to determine the most common pregnancy complications among adolescents compared to adults treated in a public hospital from 2015 to 2018. The researcher applied a convenience sampling method in selecting the medical records. The instrument used was adapted from previous studies and data were analysed with descriptive and chi-square test for the inferential statistics. A total of 1,265 patients met the eligibility criteria and 540 (42.7%) were adolescents. Low birth weight (n=478, 88.5%) and preterm delivery (n=496, 91.9%) were common among babies born to adolescent mothers. Pregnancy-related complications among adolescent mothers showing the prevalence of anaemia, hypertension, and malaria were 494 (84.9%), 149 (56.2%) and 193 (62.1%) respectively. Gestational diabetes was found to be high among adult mothers (n=98, 74.8%). Among adolescent mothers, the prevalence of eclampsia was 62 (78.5%) and hemorrhage 61 (53.0%). The prevalence of Intrauterine growth restriction (IUGR) was high among adolescent mothers (n=252, 80.5%). Comprehensive strategies are needed to keep girls in schools and to raise awareness and develop campaigns about using contraception properly to reduce the incidence of adolescent pregnancy as well as to minimise the incidence of pregnancy-related complications.

Emerging data suggest a rise in the incidence rate of hypertension in many countries within Sub-Saharan Africa. This has been attributed to socioeconomic factors that have influenced diet and reduced physical activity further deranging anthropometric measurements. We assessed the predictive power of three anthropometric indicators namely: waist circumference (WC), waist to height ratio (WHtR) and body mass index (BMI) in detecting hypertension. This cross-sectional community survey was conducted in four counties within Western Kenya between October 2018 to April 2019 among 3594 adults. The participants sociodemographic data were collected using an interviewer-administered questionnaire and anthropometric measurements taken. We used the R-software for descriptive and inferential statistical analysis. Pearson chi-square test was used to assess the association between anthropometric measurements and hypertension while logistic regressions estimated the likelihood of hypertension. Youden method was used to identify optimal anthropometric cut-offs for sensitivity, specificity and area under the receiver operating characteristics (ROC) curve computation. The crude prevalence of hypertension was 23.3%, however it rose with advancement in age. Furthermore, obese individuals had a three-fold (AOR=2.64; 95% CI: 2.09, 3.35) increased likelihood of hypertension compared to those with a normal BMI. The optimal WC cut-off was 82.5cm for men and 87cm for women, an optimal WHtR of 0.47 for men and 0.55 for women; while the optimal BMI cut-off was 23.7 kg/m2 and 22.6 kg/m2 for men and women respectively. The sensitivity of WC, WHtR and BMI for men was 0.60, 0.65 and 0.39 respectively and 0.71, 0.65 and 0.78 respectively for women. BMI is the best predictor for hypertension among women but a poor predictor for men; WC had a high hypertension predictive power for both gender while WHtR is the best hypertension predictor for men.

In the airline industry, the term load factor defined as the percentage of seats filled by revenue passengers and is used to measure efficiency and performance. This metric evaluates the airlines capacity and demand management. This paper applies stochastic models to analyse the load factor of the Association European Airlines (AEA) for flights of Europe - North Africa and Europe- Sub Saharan Africa. The estimation result prevails that the airlines have better demand management in the flights of Europe- Sub Saharan Africa than in the flight of Europe - North Africa. However, the capacity management of the airlines is poor for both regional flights. The autocorrelation structures for the load factor for both regional flights have both periodic and serial correlations. Consequently, the use of ordinal panel data models is inappropriate to capture the necessary variation of the load factor of the regional flights. Therefore, in order to control for the periodic autocorrelation, the author introduces dynamic time effects panel data regression model. Furthermore, in order to eliminate serial correlation the author applies the Prais–Winsten methodology to fit the model. Finally, the author builds realistic and robust forecasting model of the load factor of the Europe- North Africa and Europe-Sub Saharan Africa flights.

And Performance

Purpose – The purpose of this paper is to develop an effective cost borrowing model of qualitative factors that are relevant to micro and small enterprises (SMEs) better performance. Design/methodology/approach – A valid research instrument was utilized to conduct a survey on 359 SMEs (131 retail businesses, 125 service businesses, 48 farming businesses and 55 other businesses) and 897 respondents that are representative of 397 SMEs and 1,087 respondents. Correlation and regression analysis were conducted to ascertain the validity of the hypotheses. Findings – It was established that cost of borrowing elements (interest rate and loan processing costs) are associated with SME performance. Furthermore, cost of borrowing as a whole accounts for 31.1 percent of the variation in performance Uganda’s SMEs. Research limitations/implications – Only a single research methodological approach was employed, future research through interviews could be undertaken to triangulate. Multiple respondents in SMEs (owner, manager and cashier) were studied neglecting others. Furthermore, the study used the cross-sectional approach – a longitudinal approach should be employed to study the trend over years. Finally, cost of borrowing was studied and by the virtual of the results, there are other factors that contribute to SME performance that were not part of this study. Practical implications – There is need to intensify initiatives to encourage greater understanding and acceptance of cost of borrowing, select appropriate elements that includes interest rate and loan processing costs in order to have affordable source of financing to establish and grow SMEs, provide employment, competitive and contribute to countries GDP. Originality/value – This is the first paper in Sub-Saharan Africa to test empirically the relationship between cost of borrowing and performance of SMEs in the Ugandan context.

5527 Background: Following the report that VIA screening reduced cervical cancer mortality by 31% in India (ASCO LBA2 2013; Shastri SS, et al JNCI 2014), the W.H.O. endorsed VIA guidelines for Africa, where the global disease burden is highest. In Tanzania, cervical cancer is a major source of morbidity and mortality, with nearly 10,000 new cases and 7,000 deaths annually. Due to lack of resources, therapies are limited and patient outcomes are further confounded by the relatively high prevalence of concurrent HIV infection. We report on the feasibility of VIA screening in Tanzania with emphasis on unique populations. Methods: Our two 5-day VIA screen-and-treat workshops in Buzuruga and Sangabuye Health Centres in Mwanza, Tanzania were approved by the University of California, Irvine IRB and local health authorities. Participants were recruited from surrounding communities and offered free cervical VIA screening, cryotherapy when indicated, and HIV rapid testing. Acetowhite lesions and/or abnormal vascular markings were VIA+. Chi-square and Fisher exact tests were performed with statistical significance assigned at 0.05. Results: During July 2018, 825 of 917 registered participants underwent VIA screening and 25.1% (n=207) were VIA+. 147 VIA+ non-pregnant women received same day cryotherapy and 15 (1.8%) with lesions suspicious for cancer were referred to Bugando Medical Center. In the subanalysis of 64 HIV+ patients (23 diagnosed at the workshops, 41 with prior diagnosis on ART), HIV infection was not associated with VIA positivity (p=0.497). Additionally, a non-significant trend of higher VIA+ screens among newly diagnosed untreated HIV patients (27.7%) vs patients with known HIV on ART (17.5%) was observed (p=0.556). Conclusions: VIA screening for cervical cancer, while feasible in Tanzania, will require follow-up and repetitive screening. Although cervical cancer is an AIDS-defining illness, lack of correlation between HIV infection and VIA-positivity may reflect the availability of W.H.O.-subsidized ART in sub-Saharan Africa to attenuate HPV-mediated neoplastic transformation, as previously reported by others. Further study of this phenomenon is warranted.
