Abstract
Purpose
This paper intends to investigate the empirical link between governance and energy investment in PPP. To succinctly account for biases in the fixed effects (FE) model, the authors adopted different bias-corrected techniques. The majority of these techniques provided evidence that PPP investments in energy are boosted by increasing the desire for accountability, prioritising the voice of the masses and disabusing the rule of laws. This study could not find any positive influence from the control of corruption to PPP investment in energy.
Design/methodology/approach
The acute shortage of power supply in SSA has attracted PPP investments in the energy subsector of the economy, leading to the recent debate on governance and public, private investment. The authors contributed to this argument by examining the impact of country governance on PPP investment in energy using a sample of countries in SSA.
Findings
Therefore, the authors concluded that low control of corruption is responsible for the inadequate volume of PPP investments. In the light of this, the government should redefine the anti-corruption bill of their sovereignty to accommodate severe sanctions when necessary.
Originality/value
This paper uses the fixed effects (FE) model by introducing batteries of nonlinear panel models to capture the relationship between the impacts of country governance on PPP investment in energy.

Abstract
Purpose
This study aims to employ an integrated approach of geology, aeromagnetic and electrical resistivity techniques to evaluate the potential causes of abortive or low groundwater yield in most boreholes.
Design/methodology/approach
The process involved mapping geology and acquiring and processing aeromagnetic and vertical electrical sounding (VES) data. Oasis Montaj software was used for tasks like Reduction to the Equator (RTE), Upward Continuation (UC), Residual Magnetic Anomaly (RMA) and Euler Deconvolution (S. I = 1.0 and S. I = 2.0). VES utilized the Schlumberger array method, and field data underwent iterative analysis using Resist2Win software.
Findings
Total magnetic intensity (TMI) and RMA values range from −209.2 nT/m to 150.4 nT/m and −61.0 nT/m and 20.6 nT/m, respectively. High amplitude magnetic anomalies are observed in the northern and southwestern areas, indicating potential groundwater zones. Depth estimates for SI = 1.0 and 2.0 range from 11.1 m to 76.1 m and 16.4 m to 112.9 m, respectively, indicating varying overburden thickness and rock boundaries. Lineament reveals NE-SW and NW-SE trends, with hydro-lineament density ranging from low to very high. VES data identifies layers with resistivity and thickness values: topsoil (15.5–523.2 Om, 0.4–12.3 m), weathered basement (93.3–1655.7 Om, 19.0–54.7 m), fractured basement aquifer (242.7–9413.0 Om, 20.3–42.7 m) and fresh basement (62.8–935.3 Om).
Practical implications
Maps and conclusion generated from the study will serve as a baseline to solving completely the perennial problem of abortive and low groundwater yield.
Social implications
Insecurity and other vices suffered during the acquisition of data.
Originality/value
The geophysical data correlates with geological mapping, verifying that areas with dense hydro-lineaments like porphyritic granites and granite gneiss are promising aquifers. This suggests that groundwater presence is influenced by structural factors, offering valuable insights for future groundwater exploration in the study area.

Abstract
Purpose
The purpose of this study was to investigate the likely causes of failure of some sections of road pavements in Ajaokuta, Northcentral Nigeria. This was achieved through a geotechnical assessment of subgrade soils in affected areas.
Design/methodology/approach
The methods entailed field and laboratory methods and statistical analysis. Subgrade soil samples were retrieved from a depth of 1,000 mm beneath the failed portions using a hang auger. The soils were analyzed for natural moisture content (NMC), Atterberg limit (liquid limit, plastic limit and linear shrinkage), grain size distribution, compaction and California bearing ratio (CBR), respectively.
Findings
The results of the geotechnical tests ranged from NMC (12.5%–19.4%), sand (84%–98%), fines (2%–16%), LL (16.0%–32.2%), PL (17%–27.5%), LS (2.7%–6.4%), PI (2.5%–18.4%), maximum dry density (1756 kg/m2–1961 kg/m2), optimum moisture content (13.2%–20.2%), unsoaked CBR (15.5%–30.5%) and soaked CBR (8%–22%), respectively. Pearson’s correlation coefficient performed on the variables showed that some parameters exhibited a strong positive correlation with r2 > 0.5.
Research limitations/implications
Funding was the main limitation.
Originality/value
Comparing the results with Nigerian standards for road construction, and the AASHTO classification scheme, the subgrade soils are competent and possess excellent to good properties. The soils also exhibited very low plasticity, a high percentage of sand, high CBR and low NMC, which implies that it has the strength required for road pavement subgrades. The likely causes of the failures are, therefore, due to the use of poor construction materials, technical incompetence and poor compaction of sub-base materials, respectively.

Abstract
Purpose
This study investigated two key aspects: (1) how a hospital bundles limited resources for preventive care performance and (2) how to develop IS capabilities to enhance preventive care performance.
Design/methodology/approach
A case study method was adopted to examine how a hospital integrates its limited resources which leads to the need for resource bundles and an understanding of IS capabilities development to understand how they contribute to the delivery of preventive care in a Malaysian hospital.
Findings
This research proposes a comprehensive framework outlining resource-bundling and IS capabilities development to improve preventive care.
Research limitations/implications
We acknowledge that the problem of transferring and generalizing results has been a common criticism of a single case study. However, our objective was to enhance the reader’s understanding by including compelling, detailed narratives demonstrating how our research results offer practical examples that can be generalized theoretically. The findings also apply to similar-sized public hospitals in Malaysia and other developing countries, facing challenges like resource constraints, HIS adoption levels, healthcare workforce shortages, cultural and linguistic diversity, bureaucratic hurdles, and specific patient demographics and health issues. Further, lessons from this context can be usefully applied to non-healthcare service sector domains.
Practical implications
This study provides a succinct strategy for enhancing preventive care in Malaysian public hospitals, focusing on system integration and alignment with hospital strategy, workforce diversity through recruitment and mentorship, and continuous training for health equity and inclusivity. This approach aims to improve resource efficiency, communication, cultural competence, and healthcare outcomes.
Social implications
Efficiently using limited resources through HIS investment is essential to improve preventive care and reduce chronic diseases, which cause approximately nine million deaths annually in Southeast Asia, according to WHO. This issue has significantly impacted the socioeconomic development of developing countries.
Originality/value
This research refines resource orchestration theory with new mechanisms for resource mobilization, extends IS literature by identifying how strategic bundling forms specialized healthcare IS capabilities, enriches preventive care literature through actionable resource-bundling activities, and adds to HIS literature by advocating for an integrated, preventive care focus from the alignment of HIS design, people and institutional policies to address concerns raised by other research regarding the utilization of HIS in improving the quality of preventive care.
