Situating Hiv/Aids Humanitarian Film In The National Cinema Culture Of Mozambique: Historical, Contemporary And Feminist Perspectives, Sebastián Andrés Suárez Hode

University Honors Theses

The HIV/AIDS epidemic in Mozambique has enabled a new wave of humanitarian cinema to develop as it seeks to educate and empower a population that has been adversely affected by the epidemic. Colonial-era patriarchal systems that persist have resulted in Mozambican women being disproportionately impacted by the virus, and humanitarian projects in turn use film as a vehicle for the exploration of Mozambican women’s subjectivities. Thus, these films have made for an especially feminist reconditioning of Mozambican national cinema culture. This essay will explore HIV/AIDS humanitarian cinema’s place within the larger discourse of Mozambican national cinema and will demonstrate how …

Intrahousehold Relationships And Decision-Making In Extended Households Of The Luguru Community, Kamille De Backer, Nathalie Holvoet, Mursali Milanzi

Journal of International Women's Studies

This article analyses intrahousehold decision-making in extended households of the matrilinear Luguru community in the Morogoro Region of Tanzania. Our research focuses on the participation of adult “extended” household members, mainly relatives such as in-laws, grandparents, and cousins, in household decision-making. It complements studies that conceptualise household decision-making as a bargaining process between two decision-makers. We explore whether factors such as age, education, life cycle and gender play a role in this process. As decision-making processes often vary depending on the decision-making area, we differentiate between seven broad decision-making fields which are relevant in their respective settings. Our study adopts …

Testicular Torsion Induced By Epididymo-Orchitis: A Case Report, Ali Akbar Zehri, Allyzain Ismail, Philip Adebayo, Authar Ali

Faculty of Health Sciences, East Africa

Introduction and importance:

Acute scrotum is considered a urological emergency requiring early intervention depending on the cause. There are multiple causes of acute scrotum with testicular torsion being the most feared as delayed treatment leads to testicular loss. However, differentiating between epididymo-orchitis and torsion can be very difficult.

Case presentation: We present a case of an 18-year old male patient with 2 separate episodes of acute scrotum. He had epididymo-orchitis as the first presentation followed by testicular torsion 5 days later. To our knowledge this is the first case of testicular torsion secondary to epididymo-orchitis.

Knowledge, Attitudes And Practice Of Venous Thromboembolism Risk Assessment Among Surgical Doctors In Tanzania, Biswalo Mugeta Yango

Master of Medicine in General Surgery

Introduction Surgical patients are at increased risk of venous thromboembolism due to the nature of their conditions and treatments. The incidence ranges from 61.3% to 64.9% in developed countries, compared to 43% in Africa. Although venous thromboembolism is fatal, it is potentially preventable. Physician-implemented risk assessment models reduce events by 70%. No country in sub-Sahara Africa has implemented a national venous thromboembolism risk assessment guideline. The subsequent burden is probably a reflection of low awareness and knowledge, negative attitudes, and substandard practice among physicians towards risk assessment. Justification In the current study, we assessed Tanzanian surgical doctors' knowledge, attitudes, and …

Solving The University Course Timetabling Problem Using Bat Inspired Algorithm, Ushindi Limota, Egbert Mujuni, Allen Mushi

Tanzania Journal of Science

Many mathematical optimization problems from real-life applications are NP-hard, and hence no algorithm that solves them to optimality within a reasonable time is known. For this reason, metaheuristic methods are mostly preferred when their size is big. Many meta-heuristic methods have been proposed to solve various combinatorial optimization problems. One of the newly introduced metaheuristic methods is a bat-inspired algorithm, which is based on the echolocation behaviour of microbats. Bat algorithm (BA) and its variants have been used successfully to solve several optimization problems. However, from the No-free Lunch Theorem, it is known that there is no universal metaheuristic method …
