BACKGROUND Urbanisation in sub-Saharan Africa is changing lifestyles and raising non-communicable disease burden. Understanding the underlying pattern of physical activity and its correlates may inform preventive interventions. We examined correlates of objectively-measured physical activity in rural and urban Cameroon. METHODS Participants were 544 adults resident in rural (W-156, M-89) or u...

Nigeria’s cities, as elsewhere in Sub-Saharan Africa, lack adequate infrastructure for housing, sanitation, water, and open space amenities. Much of this is due to the absence of land planning statutes that encompass the evolving functions and responsibilities of urban areas, as numerous Nigerian research studies have documented. This paper reviews the status of urban planning in Nigeria and ca...

The Change of Support Problem (COSP) reflects a possibility that the outcome of an urban analysis may critically depend on the researcher’s choice of territorial units. To verify this assumption, the present study examines the association between population growth and population size of localities, using population growth data for two levels of geographic resolution 4,667 local administrative u...

Brent D. Ryan first visited Detroit in 1993. Describing this experience, he says: ‘‘The sense of emptiness was overpowering. ... I felt as if I was walking into the ruin of America.’’ In his book ‘‘Design after decline—how America rebuilds shrinking cities,’’ Ryan tries to understand why so many American cities have been losing population, what was and is done to change the fortune of these cit...

Poor outdoor air quality increases pollutants indoors. Indoor and adversely affect human health, especially in children, who are particularly vulnerable. In this study, indoor BC (Black Carbon) PM 2.5 were measured an elementary school classroom located urban city South Korea. concentrations (BC ) monitored for 7 days (140 hours) during the winter of December 2021. addition, schedule was survey...

The high rates of urbanization amidst stagnating economies and poor governance have created a new face of abject poverty concentrated in overcrowded slum settlements in Africa’s major cities. Emerging evidence demonstrates that poor residents in African cities often experience worse health vulnerabilities than many other segments of national sub-populations, including rural residents. Analysis ...

Radio wave propagation models are extremely important in radio network planning, design as well as in interference planning. Radio propagation is essential for emerging technologies with appropriate design, deployment and management strategies for any wireless network. It is heavily site specific and can vary significantly depending on terrain, frequency of operation, velocity of mobile termina...

Electronic cities result from the implication of information and communication technology (ICT) in the contemporary era. Significant ICT development and internet network expansion as well as the need of urban management to new ideas in managing cities lead us toward a new strategy called "electronic cities". The current study aims at investigating the Electronic Cities' Strategic Plan...
