DONALD J. TRUMP’S POLITICAL SLOGAN, MAKE AMERICA GREAT AGAIN: A BLENDING OF POPULISM, NOSTALGIA, AND NATIONALISM
Abdoulaye DRABO; Harrouna MALGOURI; Wôkoudo Marcel MASSIMBO; Aouia BADJIOUThis paper addresses the lack of a comprehensive analysis of the ideological components of Donald J. Trump’s “Make America Great Again” (MAGA) slogan by
examining how it served as a rhetorical tool to win the 2016 presidential election. In this paper we qualitatively and conceptually analyze Trump’s campaign materials from 2015–2016 using Cas Mudde’s populism (2004), Svetlana Boym’s restorative nostalgia (2001), and Rogers Brubaker’s exclusionary nationalism (1992). The obtained results
demonstrate that Trump’s MAGA entailed a synthesis of three key elements: an exclusionary nationalism embodied in “America First” policies and America’s border
strict control; a restorative nostalgia for an idealized post-WWII past to counter anxieties about deindustrialization and American demographic change; and a Manichean populist struggle between what Trump calls “forgotten Americans” and a corrup...

Governance deficits in urban mobility systems: Institutional coordination, capacity gaps and planning challenges in Ouagadougou (Burkina Faso)
Mohamed Ibrahim BALLO, Houd KANAZOE, Joseph YAMEOGORapid urbanisation in African cities has intensified pressures on urban mobility systems. In Ouagadougou, sustained population growth, urban sprawl, and rising travel demand continue to challenge the efficiency of urban transport despite ongoing investments in infrastructure and services. This study examines the institutional, organisational, and regulatory factors affecting urban mobility governance in the city. A mixed-methods approach was adopted, combining documentary review, questionnaire surveys administered to 300 stakeholders, semi-structured interviews, field observations, and SWOT analysis. Quantitative data were analysed using SPSS, while qualitative information was subjected to content analysis. The findings reveal that although multiple actors are involved in urban mobility governance, coordination remains weak. Most respondents considered existing coordination mechanisms in...

Spatio-temporal analysis of extreme rainfall indices in Burkina Faso using RClimDex
Joseph Yaméogo, Boureima Yo, Alimata Zorom and Pawendkisgou Isidore YanogoThis study examines extreme precipitation trends across Burkina Faso’s Sahelian, Sudano-Sahelian, and Sudanian zones from 1991 to 2023, amid growing hydro-climatic variability in West Africa. The aim is to determine whether changes in rainfall extremes reflect gradual trends, structural shifts, or both. Three indices were analyzed: maximum 1-day precipitation (RX1day), maximum consecutive 5-day precipitation (RX5day), and the Simple Daily Intensity Index (SDII), using a non-parametric framework combining Mann – Kendall trends, Sen’s slope, and Pettitt change-point tests (p < 0.05), with spatial patterns mapped via GIS. Results show a latitudinal contrast. In the Sahelian zone, Dori recorded a significant SDII change in 2004 (p = 0.040) followed by increasing intensity. The Sudano-Sahelian zone exhibits the strongest signal: Ouagadougou shows upward trends in RX5day and SDII with a struct...

Ethnovariety Diversity, Endogenous Sustainable Management Strategies, and Socio-Cultural Services of Calabash [Lagenaria siceraria (Molina) Standl.] in Burkina Faso: An Ethnobotanical Study
Abel Sawadogo, Karim Abdou Traoré , Fanta Reine Sheirita Tietiambou, Mariam Kiébré, Hamid El Bilali, and Zakaria KiébréCalabash (Lagenaria siceraria (Molina) Standl.) has long been an essential species for communities in Africa. Over the past decades, its production has gradually declined. Developing knowledge of existing ethnovarieties and the causes of their decline, as well of the socio-cultural services associated with the ethnovarieties and the chosen local management strategies, could contribute to their better valorization and conservation. This study aims to (i) map existing ethnovarieties, (ii) determine the endogenous management strategies, (iii) document the socio-cultural services associated with the ethnovarieties, and (iv) determine the causes of the decline. First, a non-probabilistic snowball sampling technique was used to identify the producers to be involved in the study. Then, semi-structured interviews involving 80 producers from 8 provinces across Burkina Faso were conducted using a...

M'Po, Franck Le Sage Téounviel Somda, Isaac Saamou Boni, Hadidiatou Belem, Windmi Kagambéga and Roland N.T. MedaThe use of medicinal plants remains an essential practice in sub-Saharan Africa, where they constitute a major therapeutic and socio-cultural resource objective of the study was to investigate medicinal plants used for doping in the city of Bobo-Dioulasso. Methods: To do this, a semi-structured ethnobotanical survey was first conducted among traditional practitioners. Phytochemical compositions of the plants were analyzed using spectrophotometry. Finally, the acute toxicity of the doping plants was studied by administering a single dose of 5000 mg/kg body weight to NRMI mice, which were observed for 14 days. Results: A total of 50 traditional practitioners and herbalists were interviewed and 25 plants species belonging to 17 botanical families were identified. Based on the frequency of citation, the species Martynia annua Lin (Martyniaceae), Securidaca longepedunculata Fresen (Polygalace...

Flexible Dependence Modeling for VaR Using Bernstein’s Copula
Vini Yves Bernadin Loyara, Fabrice Ouoba Kpèbbèwèrè Cédric Somé , Remi Guillaume Bagré and Diakarya BarroIn this work, we establish theoretical and numerical links between the Bernstein copula, the Bernstein polynomial, and Value at Risk (VaR) in the context of dependence approximation in financial risk. Thanks to the smoothing induced by this copula, we express the portfolio VaR as the quantile of an approximate joint distribution, highlighting the effect of Bernstein smoothing on the estimation of extreme risk.
