The Four-Step model of transportation planning and modal choice provided the theoretical basis for this study. A survey research design involving a stratified sampling technique was adopted. The descriptives on transport modes, amount and time spent revealed that 10 (76.9%) males and 3 (23.1%) females preferred bicycle as means of transportation, 7 (58.3%) males and 5 (41.7%) females preferred motorcycle, while a significant proportion 90 (53.9%) males and 77 (46.1%) females preferred tricycle, 80 (63.0%) males and 47 (37.0%) females preferred cars/taxis, and 12 (46.2%) males and 14 (53.8%) females preferred mass transit bus. However, 14 (46.7%) males and 16 (53.3%) females in marshy terrain and coastal locations preferred canoes and boats. The result of the logistic regression model revealed that gender modal preference is more likely to be influenced by mode of transportation with a beta weight of 1.140, safety considerations 1.139, ownership of transport 1.135 and distance to place of work 1.073. Hence, this study recommends that a combination of these factors should be incorporated into transport planning to achieve effective transport planning and sustainable development in the Yenagoa metropolis.展开更多

This study investigated the species composition of fresh water snail intermediate host in Amassoma community and the Niger Delta University Campuses during August 2019-October 2019 across five locations (Main campus Hostel, E.T.F Building, Ogboebi-Ama, Efeke-Ama, Ogbopina). Snails were collected from the water bodies with the aid of a scooping net and hand picking. The morphological identification of the snail intermediate host followed standard procedures. From the result, five hundred and seventy-one freshwater snails belonging to four genera and five species were recorded. The presence of Lymnae and Bulinus in the locations highlights foci for fascioliasis and schistosomiasis. The presence of Melanoides spp. is novel in Bayelsa State. The public health implications of these snails have called for timely control intervention.展开更多

It is a common phenomenon in the urban centres of the developing nations where most houses are in deplorable conditions. The houses are overcrowded with little or no air space between them. There is no basic sanitation in the urban centres as they lack flush toilet, some of the few available flush toilets are piped into seasonal streams, most houses lack defined kitchen areas and healthy sewage disposal method. The cities lack good access roads and functional drainage system with a common practice of environmentally-unfriendly solid waste management methods that create various health challenges to urban dwellers. The aim of the study is to show how in-situ Housing method of slum rehabilitation can be applied through Public/Private Partnership to upgrade houses within a major slum area in Yenagoa. This shall be done with an agreement between the property owners, Real Estate investors and the state government. Basic Research Methodology was applied using questionnaire, direct observation and personal interview techniques to collect data. Both qualitative and quantitative techniques were applied to analyse data through the use of tables and charts. The findings in the study showed that poor housing condition seriously degrade the environmental quality of the study area. The standard of living in the area is very poor as the people lack access to decent accommodation, basic sanitation and social amenities.展开更多
