Application of DPSIR model to ascertain driving forces and their impacts on the Volta basin.

Managing trans-boundary water and its watershed areas is a challenging task. The riparian countries sharing the boundary may have different economic and national goals that can dictate the pressures exerted on water bodies and their catchments areas. The pressure will have dire consequences on the environment, the climate and the sustainability of the Volta River.

From theories of contraceptive use to human rights principles: implications for indicators on the supply and demand side.

In this commentary, we examine the evolution of theories and metrics regarding contraception. We contend that while human rights principles are now widely integrated into the "supply-side factors" of contraceptive provision, particularly through the concept of quality of care and its metrics, their role in relation to "demand-side factors" remains ambiguous. We propose that human rights represent one of several normative frameworks to which both users and non-users may adhere when shaping their fertility preferences and decisions regarding contraception.

This study assessed the impact of an innovative nine-months multi-media campaign engaging a key influencer, aimed at empowering consumers to choose safer ready-to-eat chicken meat at informal street restaurants in Ouagadougou, Burkina Faso. A two-wave panel study assessed associations between recall of TV, radio, billboard, and social media advertisements, and self-reported behavior regarding purchasing and consumption of ready-to-eat chicken at outlets, consumer intentions, knowledge, attitudes, norms, and agency.

Toward a conceptualization of decent work in Africa: Development and cross-cultural validation of the Decent Work Triad (DWT) in Burkina Faso, Switzerland, and Togo.

Psychology of Working theorists recommend supplementing the Decent Work Scale (DWS) with subjective investigations of decent work across different cultural contexts. Building on this, the present study developed and validated the Decent Work Triad (DWT) for assessing the subjective aspects of decent work in a sub-Saharan African context. Using a Burkinabe sample for exploratory ( = 303) and confirmatory ( = 494) analyses, it consists of 8 items assessing three moral and value-based dimensions: Dignity, Corruption-Free, and Shamelessness.

Environmental impacts of a stand-alone photovoltaic system in sub-saharan Africa: A case study in Burkina Faso.

The costs and the potential allocation of costs of bouillon fortification: The cases of Nigeria, Senegal, and Burkina Faso.

Food and condiment fortification programs are needed to address micronutrient deficiencies and their health, developmental, and mortality consequences; but these programs are never free. Knowing program costs and their allocation across stakeholders is essential to design and manage effective, efficient, and sustainable programs. We developed 10-year hypothetical bouillon fortification program cost models for Nigeria, Senegal, and Burkina Faso that included start-up and operational costs for government and industry, as well as premix costs generated by an embedded premix cost calculator to allow for alternative premix formulas in cost calculations.

Crimean Congo hemorrhagic fever virus exposure among febrile patients, cattle herders, and cattle herds in Cameroon.

Problem Addressed: Crimean Congo hemorrhagic fever (CCHF) is a tick-borne disease with high fatality rates and an expansive geographic distribution, yet disease prevalence data in Cameroon is lacking.

Objective: This study aimed to determine CCHF virus (CCHFV) seroprevalence and tick distribution among cattle herders and febrile patients in West and Centre Cameroon.

Methods And Approach: Two cross-sectional serological studies of human and cattle were conducted from October to December 2021 and from June to July 2022, which included the collection of ticks.

Optimizing the survey design for assessing schistosomiasis at the sub-district for treatment decision making.

Background: Schistosomiasis control programs typically launch with district-level, school-based preventive chemotherapy (PC). Recent World Health Organization recommendations are to shift to community-wide treatment where schistosomiasis prevalence is >10%. Simultaneously there is a push to move to sub-district PC to prioritize communities in need of treatment and alleviate the pressure on global praziquantel need, but few countries have sub-district prevalence data and no guidelines on how to collect this information.

In-Depth Study of Ambipolar Charge-Transport Regime through External Triggers and Gas Sensing.

Ambipolar devices are a hot topic in research tables due to their unique advantage in reducing the size of the electrical system and enhancing its efficiency. Here, we report a bilayer heterojunction device constructed using octafluoro-vanadyl-phthalocyanine (VOFPc) and lutetium bisphthalocyanine (LuPc), which exhibits both p- and n-type behaviors under oxidizing (NO and O) and reducing gas (NH) species depending on the humidity level and temperature variations. The initial polarity of the device is identified as n-type by measuring a current decrease under oxygen exposure.
