This article aims to enhance understanding of the changing nature of the pre-colonial, (neo)colonial and postcolonial imagination of space and time in Africa and of its organising principle in African cinema. It will focus on the cartographic and time reckoning techniques and traditions of Africans in precolonial times in contrast to the space-time imagination expressed in colonial film in Africa, such as in the instruction documentary Daybreak in Udi (1949). This documentary, which promotes British colonial self-help development projects in Africa, (...) tells the story of the building of a maternity home in an Igbo village in Nigeria. Furthermore, the article will enhance understanding of the cinematic turn to a counterhegemonic film tradition as a stepping stone to the newly emerging field of African intercultural philosophical cinema. The time-space imagination in Common Threads (2018), shortlisted by the Zanzibar International Film Festival (ZIFF) for the best documentary will be analysed as a case in point. This documentary concentrates on the nineteenth-century and current Afro-Indian textile trade, the associated oral narratives and their visual impact on the so-called Kanga and Vitenge textiles.

Background: Socio-epidemiological data of dental caries helps to plan effective community interventions. Objective: To estimate the prevalence and assess the experience of dental caries among school going adolescents in a rural area of Bangladesh. Methods: A cross-sectional study was donein Sylhet District in Bangladesh, between January and December of 2014. Students of class VIII, IX and X, aged 12-16 years were taken for the study. A total of 90 studentswere divided into 12-14 years and 15-16 years age groups using simple (...) random sampling technique. A pre-designed, self-administered questionnaire was used for demographic survey. Students were examined for dental caries. Assessment of Experience of dental caries was done by Decayed, Missing and Filled teeth (DMFT) index. Results: The mean age of the respondents was 14.37±0.50 years. Females were 68(75.6%) and males were 22(24.4%). 31(34.4%), 30 (33.3%) and 29(32.2%) were from VIII, IX and X respectively. The older age group (15-16 years) had more decayed teeth than that of 12-14 years group (2.28 vs. 1.46; p=0.04). The mean DMFT score was lower in male compared to female (1.43 vs. 2.30; p>0.05).There was significant difference in the total DMFT score among the classes (p=0.009). Mean DMFT score was 1.88. Caries prevalence was 42.2% in the maxillary arch and 58.9% in the mandibular arch. Among males, the mandibular arch showed a higher caries level (63.64%) than the maxillary arch (40%), while in females, in maxillary and mandibular archeswere 42.64% and 42.65% respectively (p>0.05). Conclusion: 64.4% of the study population had dental caries with male predominance; mandibular arch was more involved. (shrink)
