Facilitating Accommodation Of Learners With Disabilities In Summative Assessment Of Literacies In Tanzania Through Mobile Application, Musa Saimon, Fredrick Mtenzi

Institute for Educational Development, East Africa

Summative Assessment of Language Literacies in Tanzania is administered in the form of a Paper-and-pencil assessment. This kind of assessment hardly accommodates learners with disabilities such as visually impaired ones because it does not allow adjustment of the font size to suit the reader’s needs. As a result, such students might end up being judged as failures in such assessments while their failure is attributed to the nature of the assessment rather than their lack of competence in language literacies. Therefore, to improve the existing situation, the present study investigated the contribution of mobile applications to accommodating learners with diverse …

Complete Neighbourhood Search Heuristic Algorithm For Portfolio Optimization, Collether John

Tanzania Journal of Engineering and Technology (TJET)

In portfolio optimization, the fundamental goal of an investor is to optimally allocate investments between different assets. Mean-variance optimization methods make unrealistic assumptions to solve the problem of optimal allocation. On the other hand, when realistic constraints like holding size and cardinality are introduced it leads to optimal asset allocation which differ from the mean variance optimization. The resulting optimization problem become quite complex as it exhibits multiple local extrema and discontinuities. Heuristic algorithms work well for the complex problem. Therefore, a heuristic algorithm is developed which is based on hill climbing complete (HC-C). It is utilized to solve the …
