Abstract

This study explores the potential of emerging technologies aiming to transform the Nigerian construction industry. The technologies offer innovative solutions to persistent challenges such as inefficiencies, project delays, cost overruns, and safety risks. The Nigerian construction industry (NCI) is, however, reluctant to implement the technologies because of a lack of substantive comprehension of the features of the innovative technologies. Hence, it has become necessary for the NCI to fully understand the benefits and challenges of the emerging technologies for construction project efficiency. The exploratory literature review identified and examined seventeen (17) emerging technologies, revealing sufficient practical benefits such as enhancing productivity, improving safety, saving costs, and increasing transparency. It also identifies some barriers to their adoption, such as high implementation costs, a lack of skilled professionals, resistance to change, and a technological knowledge gap. The findings suggest that while NCI has started adopting these technologies, significant efforts are needed to address infrastructural limitations and promote skill development. The study concludes by discussing the implications of the findings for construction firms and policymakers and recommendations for future research on the adoption of automation technologies in developing economies, particularly Nigeria.

Abstract

It seems that Nigeria's educational system has been undergoing improvement only on quantitative when it comes to the number of enrolments in students and schools. However, little effort has been put in place in terms of capacity (physical and material resources, human and financial resources) to manage high enrollment. Resources capacity in secondary schools was nothing to write home about. Most of these resources in secondary school were dilapidated. To worsen the scenario, the scarce resources allocated to these schools are grossly inadequate compared to students' enrollment and come late to the end-users in the public secondary schools. The various stakeholders in the education sector express stern concern about the consistently poor performance of students in secondary schools, especially in mathematics. Since secondary school education is expected to be free by the government, coupled with population increase, it is reasonable for people to take advantage of the free education program. Although the government and private sector of education keep providing qualified teaching staff and non-teaching staff, students in secondary schools still face poor performance in mathematics. The effect of all these on the academic performance in Nigeria's mathematics secondary school students concerns researchers of this empirical work. It is based on these issues and many more that this work sought to empirically investigate the impact of resource factors and quality of instruction on the performance of Nigeria secondary school students in mathematics.

Abstract

This study investigates the relationship between digital transformation and e-governance effectiveness in Malaysia’s public sector, employing an integrated model based on the Technology–Organization–Environment (TOE) framework and the Unified Theory of Acceptance and Use of Technology (UTAUT). Despite Malaysia’s progressive digital initiatives under the MyDIGITAL Blueprint and the Public Sector Digitalisation Strategic Plan (2021–2025), variations persist in the implementation and utilization of e-government systems across ministries and agencies. Using a quantitative research design, data were collected from 354 civil servants across federal and state institutions in Putrajaya, Kuala Lumpur, and Selangor. Partial Least Squares Structural Equation Modeling (PLS-SEM) was applied to examine the effects of technological readiness, organizational capability, environmental policy support, performance expectancy, and facilitating conditions on e-governance effectiveness. The results reveal that all five constructs significantly influence e-governance effectiveness, explaining 68.1% of its variance. Among these, organizational capability emerged as the strongest predictor, followed by environmental policy support and facilitating conditions. The findings highlight that the success of digital transformation in Malaysia’s public sector depends not only on technological infrastructure but also on institutional readiness, supportive policy environments, and user acceptance. The study contributes theoretically by empirically validating an integrated TOE–UTAUT model in a developing-country public sector context and offers practical insights for strengthening interoperability, capacity building, and citizen-centric digital service delivery.

Abstract

Locust Bean Pod Ash (LBPA) is produced from the calcination of Locust Bean Pod (LBP), an agricultural waste of the African locust bean tree (Parkia biglobosa). This study evaluated the use of LBPA obtained through controlled calcination and open burning as a supplementary cementitious material (SCM) in high-strength concrete (HSC). Cement was replaced by LBPA at 5%, 10%, 15%, and 20% by weight using both ashes—LC for ash produced through calcination at 600 °C, and LO for ash obtained through open burning. Slump and strength were assessed, including compressive strength (100 × 100 × 100 mm cubes) and splitting tensile strength (100 × 200 mm cylinders) up to 90 days. The results showed that LC contained 42.81% and LO contained 10.69% combined SiO₂, Al₂O₃, and Fe₂O₃. The 5% replacement level produced the best performance for both LBPA types. At 90 days, LC and LO improved compressive strength by 14.48% (68.8 N/mm²) and 10.48% (66.4 N/mm²), respectively, compared to the control (60.1 N/mm²). Similarly, the tensile strengths of LC05 and LO05 were 6.74% (4.75 N/mm²) and 4.94% (4.67 N/mm²) higher than the control (4.45 N/mm²). The study concludes that both ashes can be used as SCMs in HSC, with 5% and 10% recommended as optimum replacement levels for calcined and openly burnt LBP, respectively.
