Child mortality remains a critical challenge in conflict affected Borno State, Nigeria, where insecurity, displacement, and poverty have heightened vulnerabilities. This study aimed to model under five child mortality using a Weibull accelerated failure time (AFT) model and identify predictors of survival in Maiduguri. A secondary dataset of 141 children was analyzed. The Weibull AFT model included gender, birth weight, immunization status, mother’s age, antenatal care (ANC) visits, place of delivery, residence, water source, malaria, and diarrhea history. The model showed excellent fit (likelihood ratio χ² = 40.56, p = 1.3×10; AIC full model = 171.9 vs. null = 192.5). The scale parameter (σ = 0.414) indicated highest mortality risk in early infancy. Significant protective factors were higher birth weight (HR = 0.55, p = 0.034), complete immunization (HR = 0.19, p = 0.002), and older maternal age (HR = 0.90, p = 0.027). ANC visits showed a paradoxical increased hazard (HR = 1.74, p = 0.006), suggesting reverse causality. Other variables were not significant. The Weibull model effectively identified key determinants of child survival. The ANC finding warrants further investigation. Future research should compare discriminant analysis and logistic regression against the Weibull baseline in humanitarian contexts.

The poor performance of students in O’ level chemistry practical has been attributed to many factors. Some of these factors are lack of science equipments, inability of students to identify colour of gases, inability of students to express facts and thought explicitly in writings, lack of knowledge of underlying principles of qualitative analysis, and rationale for common laboratory practices and inability of students to apply basic principles of mathematics correctly. This paper highlights some ways and steps in teaching practical chemistry effectively. To ensure effective practical teaching, it is recommended that government should ensure that schools have functional laboratories, qualified and well-trained science teachers, provide good textbooks and to ensure periodic supervision of schools. The teachers on their part, should use correct teaching method, teach correct concepts and should expose students to practical early enough to avoid the fire brigade approach towards passing WAEC or NECO examination and also avoid overcrowding of students during practical.
