The empirical evidence is based on panel smooth transition regressions (PSTR). The nexus between economic growth and natural resources is not linear and the underlying non‐linearity is contingent on existing infrastructural and governance levels. Evidence of a “natural resource curse” is apparent in countries with extremely low levels of governance and infrastructural development. The favorable effect of natural resources on economic growth requires a governance threshold of −1.210 and an infrastructure threshold of 2.583, indicating that countries with governance and infrastructure levels higher than these values tend to benefit much more from the wealth of natural resources. Countries identified below the established thresholds are mainly from Africa. Policy implications are discussed with specific emphasis on African countries.Ali, Hamid E., and Shahjahan Bhuiyan. 2022. “Governance, Natural Resources Rent, and Infrastructure Development: Evidence from the Middle East and North Africa.” Politics & Policy 50(2): 408–40. https://doi.org/10.1111/polp.12451.Asiegbu, Martin F., Okey Marcellus Ikeanyibe, Pius Otu Abang, Okwudili Chukwuma Nwosu, and Chuka Eugene Ugwu. 2024. “Natural Resource Fund Governance and the Institutionalization of Rent Seeking in Nigeria's Oil Sector.” Politics & Policy 52(1): 169–95. https://doi.org/10.1111/polp.12579.Ikeanyibe, Okechukwu M. 2018. “Bureaucratic Politics and the Implementation of Liberalization Reforms in Nigeria: A Study of the Unbundling and Reorganization of the Nigerian National Petroleum Corporation.” Politics & Policy 46(2): 263–94. https://doi.org/10.1111/polp.12249.

The paper aims to investigate the legitimacy of the African Union by examining the socio‐demographic determinants of citizens' support of African integration. To do this, we use Rounds 4, 5, 6, and 8 of the Afrobarometer survey data corresponding to more than 110,000 respondents. Using logistics regressions, we find that individual characteristics such as living area, education, employment status, political membership, freedom, living conditions, and Living Poverty Index (LPI) are significantly related to the probability of supporting African integration. The findings are largely robust to dynamics of regional integration, the African Union, and Regional Economic Communities (RECs). Thus, since African citizens' trust in the unification could be considered a condition of legitimacy in the process, our results suggest that more efforts should be made to gain credibility, especially as it pertains to the benefits of African integration.

This study examines the nexus between governance and human development in Africa. It uses data for the period 2010–2019 and takes into account the existence of spatial dependence and controls for the endogeneity problem through a Generalized Spatial Two Stage Least Squares (2SLS) technique. The exploratory spatial data analysis reveals the existence of spatial dependence on human development and governance quality. Our empirical findings support that in Africa, "good fences make good neighbors," or proximity matters in the distribution of human development. Implications are discussed. This study complements the extant literature by using more updated data and employing an alternative and more robust estimation approach. [ABSTRACT FROM AUTHOR]

The purpose of this study is to understand how countries have leveraged on their economic resilience to fight the COVID-19 pandemic. The focus is on a global sample of 150 countries. The study develops a health vulnerability index (HVI) and leverages on an existing economic resilience index (ERI) to provide four main scenarios from which to understand the problem statement, namely 'low HVI-low ERI,' 'high HVI-low ERI,' 'high HVI-high ERI,' and 'low HVI-high ERI' quadrants. Countries that have robustly fought the pandemic are those in the 'low HVI-high ERI' quadrant and, to a lesser extent, countries in the 'low HVI-low ERI' quadrant. Most European countries, namely one African country (Rwanda), four Asian countries (e.g., Japan, China, South Korea, and Thailand), and six American countries (e.g., United States, Canada, Uruguay, Panama, Argentina, and Costa Rica) are apparent in the ideal quadrant.

This study complements the extant literature by constructing COVID‐19 economic vulnerability and resilience indexes using a global sample of 150 countries categorised into four principal regions: Africa, Asia‐Pacific and the Middle East, America, and Europe. Seven variables are used for the vulnerability index and nine for the resilience index. Both regions and sampled countries are classified in terms of the two proposed and computed indexes. The classification of countries is also provided in terms of four scenarios pertaining to vulnerability and resilience characteristics: low vulnerability‐low resilience, high vulnerability‐low resilience, high vulnerability‐high resilience, and low vulnerability‐high resilience to illustrate sensitive, severe, asymptomatic, and best cases, respectively. The findings are relevant to policy makers, especially as they pertain to decision‐making in resource allocation in the fight against the global pandemic. [ABSTRACT FROM AUTHOR]

This study has: (a) analysed the economic impact of the Covid‐19 pandemic, (b) evaluated the effectiveness and relevance of different measures against the pandemic and (c) examined nexuses between the corresponding measures and economic outcomes. The study uses a sample of 186 countries divided into four main regions, notably: Asia‐Pacific and the Middle East, Europe, Africa and America. Thirty four preventing and mitigating measures against the Covid‐19 pandemic are classified into five main categories: lockdown, movement restrictions, governance and economic, social distancing, and public health measures. The empirical evidence is based on comparative difference in means tests and correlation analyses. The findings show how the effectiveness and consequences of the Covid‐19 measures are different across regions. In adopting the relevant policies to fight the ongoing pandemic, the comparative insights from the findings in the study are worthwhile. Inter alia: (a) from a holistic perspective, only European countries have favorably benefited from the Covid‐19 measures; (b) lockdown measures at the global level have not been significant in reducing the pandemic; (c) the restriction of movement measure has been relevant in curbing the spread in the American continent; (d) the enforcement of the social distancing measures has been productive in Europe and counter‐productive in Africa; (e) governance and economic measures have exclusively been relevant in Europe and (f) overall public health measures have not had the desired outcomes in flattening the infection curve probably because most of the underlying measures are awareness decisions or oriented toward people already infected.

Knowing the dispersal of released insects and estimating the size of field populations are keys to the successful implementation of area‐wide management (AWM) programmes based on the sterile insect technique (SIT), as they determine the release strategy of sterile males. Mark–release–recapture (MRR) is a common method used to estimate field populations and spatiotemporal dynamics. However, the extent to which the pest is attracted to lures is often difficult to identify, thereby biasing extrapolation to movement patterns and population size. We performed MRR experiments on the Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in a fruit‐growing area in Senegal. Methyl eugenol and protein baits were used to trap males and females, respectively. After studying the suitability of marking B. dorsalis with fluorescent pigments at the laboratory, two releases of marked sterile flies were organized in the centre of an organic mango orchard, first in the late mango fruiting stage and second in the fruit setting stage. Traps were placed symmetrically along a 250 and 500 m radius from the release point. A very small fraction of the released individuals was recaptured: 0.45% in the first release and 3.08% in the second. Trapping of both sterile and wild flies was completely anisotropic. Sterile flies were mostly trapped at a relatively short distance (250 m) from the release point, in the first two days. Male trapping using methyl eugenol was highly effective, whereas the response of females to food bait traps was low. The direction of the wind was the main driver of recapture, with flies heading upwind. The results underline the importance of taking the odour plume around the traps into account when estimating populations, and the heterogeneous spread of the wild population in the landscape for the set‐up of the release strategy of sterile insects for SIT‐based AWM.
