Impact of productive social safety net on households' vulnerability to poverty in Tanzania.

Social safety nets are expanding in Sub-Saharan Africa. While proponents perceive them as a means to combat poverty and vulnerability, opponents view them as wasteful use of scarce public resources and do not significantly overcome poverty. Previous studies have primarily focused on assessing the impact of these policies on current poverty levels, with insufficient evidence available regarding their impact on future poverty, which deserves equal attention.

Creating sustainable capacity for river science in the Congo basin through the CRuHM project.

In this article, we examine the scientific and sustainable research capacity outcomes of the 'Congo River: user Hydraulics and Morphology' or CRuHM project, a six-year effort supported by the Royal Society's Africa Capacity Building Initiative.

Materials And Methods: Personal and area air samples for RCS were collected during tanzanite mining operations before and after improved work practices employed to reduce exposures and analyzed using X-ray diffraction.

Efficacy of waste stabilization ponds and constructed wetlands adopted for treating faecal sludge in Africa: a review.

The generation of faecal sludge (FS) in capitals and urban settings of African countries outpaces the available storage, emptying, transportation and treatment technologies. The low technology-based treatment systems for handling FS are preferable and widely adopted in the African context due to their less associated investment and operation costs. The waste stabilization ponds and constructed wetlands were principally developed as wastewater treatment systems however they are widely adopted for treating FS in urban settings of Africa.

Evaluating the performance of faecal sludge dewatering technologies in urban settings of developing African countries: a review.

Inadequate dewatering technologies are reported as the dominant challenge in handling faecal sludge (FS) within urban settings of most African countries. Studies have been carried out to evaluate the efficiencies of unplanted sand drying beds (USDBs), decentralized wastewater treatment systems (DEWATS), and geo-tubes. However, limited information is available on comparative capabilities in dewatering the FS.

Exploring pre-crash gate violations behaviors of drivers at highway-rail grade crossings using a mixed multinomial logit model.

The highway-rail grade crossings (HRGCs) across the United States have been experiencing about 2500 crashes each year. Previous studies analyzed crash frequencies and fatalities; however, factors pertaining to drivers' gate violation behaviors are little known. Also, applied methodologies for gate violation behaviors analysis did not consider their heterogeneity across regions.

Institutional quality and resource-based economic sustainability: the mediation effects of resource governance.

Unlabelled: The discovery of extractive resources is associated with multiple opportunities and unbridled optimism on achieving socio-economic development for many countries. However, the question how the host governments meet expectations of indigenous people by ensuring an ideal resource-based economic sustainability (RES) has been receiving less research attention. Using the global panel dataset of 80 resource-endowed economies from 2010 to 2017, we postulate and empirically examine the mediating effect of the resource governance (RESOGV) on the relationship between institutional quality (IQ) and RES.

"From experts to locals hands" healthcare service planning in sub-Saharan Africa: an insight from the integrated community case management of Ghana.
