Bambara groundnut is a hard-to-cook grain and this has limited its utilisation to some extent. However, the grain is a good source of phytochemicals with antioxidant properties. This study investigated the total phenol content, antioxidant, anti-inflammatory and anti-microbial potentials of hot-water extract of four Bambara groundnuts differentiated by their seed coats (cream, black, maroon and brown).

Bambara grains were heated in water at a ratio 1:20 (w/v) and the grains brought to boiling in a controlled water bath. As soon as boiling started, the temperature was reduced to 90 °C to reduce the evaporation rate. The extracts were withdrawn within 30 min, which was chosen from a preliminary study where beyond this time, the extract was drying off and the amount of solution obtained was not sufficient for the initial run. Grain colour and composition and antioxidant, antimicrobial and anti-inflammatory properties of the extract were determined using standard methods.

Protein (20.57–26.31%) and carbohydrate (55.43–61.09%) were the major components of the grain. Grain type and boiling time generally affected the total phenolic content of the extract. Cream Bambara displayed substantially lower total phenolic content at all boiling times compared with the maroon, brown and black Bambara groundnuts. The total flavonoid contents and total phenolic contents of the Bambara groundnut extracts were dependent on the boiling time and type of grain. The extracts showed no activity against Candida albicans, but the maroon coat Bambara demonstrated a peak inhibition of 6.00 mm against Escherichia coli. The total phenolic, flavonoid contents and the antioxidant properties of the grains generally followed the order Maroon > Black > Brown.

This study has demonstrated the possibility of promoting the use of Bambara groundnut beyond the current level of usage by using simple processing method of boiling to extract phytochemicals with medicinal properties.

Although social media has gained prominence as a communication and marketing tool in various sectors, its adoption and utilization within the construction industry remain relatively underexplored. Therefore, this study fills this gap by evaluating the level of awareness and the extent of adoption of social media within the Nigerian construction industry, shedding light on its current status and potential impact.

This objective was attained via a quantitative research approach that utilized a structured questionnaire to obtain responses from construction professionals such as architects, builders, engineers, quantity surveyors and estate managers. Frequencies and percentages and the mean item score (MIS) were used to analyze the questionnaire responses and assess the overall awareness and adoption of social media among construction professionals. Additionally, the Kruskal–Wallis H-test provided valuable insights into the variations in social media adoption levels among different professional categories within the construction industry.

The results indicate that construction professionals possess a generally high level of awareness regarding various social media platforms. However, despite this awareness, the extent of adoption does not align with the level of awareness, suggesting that adoption rates are not as widespread as anticipated.

The findings of this study underscore the importance of not just awareness but also effective adoption and utilization of social media platforms. While awareness is a crucial first step, construction firms should focus on implementing strategies to encourage greater adoption and integration of these platforms into their daily operations. This can go a long way in bridging the awareness – adoption gap which was revealed in this study.

While the limited existing research on social media in the construction industry has predominantly concentrated on areas such as marketing, addressing the root causes of fatalities, data environment tools and business branding, none have undertaken a thorough evaluation of social media awareness and adoption within the sector. This study fills a critical gap by narrowing its focus to the adoption dynamics and the technology’s potential impact on communication, collaboration and knowledge sharing among construction professionals.

Green building (GB) development is attracting interest globally, yet many fast-growing countries (FGCs) are underperforming in GB delivery, particularly in Africa and Southeast Asia. This study aims to identify pathways for accelerating GB development in FGCs, using Nigeria as a case study.

Three-fold research data was employed. First, seven policy documents that are relevant for GB development in Nigeria were sourced, reviewed and analyzed based on content analysis. Second, a systematic literature review (SLR) of thirty-five research articles sourced from the Scopus database was conducted to underscore key research outcomes. Third, an exploratory case study of sixteen GBs was conducted to contextualize the current practice status in Nigeria.

The findings revealed that the few policy efforts in Nigeria skewed largely towards energy efficiency. The challenges associated with GB growth include low level of competency, low investment in the GB market, the dearth of technological enablers and the scarcity of GB project cases. Current project initiatives are diminutive, revealing low certification achievement and scanty public sector participation.

This paper presents a unique position for accelerating sustainable architecture and construction based on policy pathways (development of novel codes and sectorial policies, harmonization of standards and performance monitoring), research pathways (development of models, technological enablers and knowledge management) and practice pathways (capacity building, public investment and sectorial collaborations).

The paper developed an integrated three-pathway framework for bringing Nigeria’s construction industry up to speed in GB delivery, noting areas where other FGCs need to explore.

In several developing contexts, the delivery of Architecture, Engineering Construction and Operation (AECO) projects continually grapples with issues such as fragmented communication, a lack of transparency, safety and risk management concerns. These problems result from the use of traditional construction practices and insufficient technology integration. Therefore, there is a pressing need to enhance communication, transparency and collaboration within construction projects in these countries through the improved utilization of innovative tools. Consequently, this study empirically assesses both the application areas and the benefits associated with the adoption of social media within the Nigerian construction industry.

This study employed a quantitative research approach that utilized a structured questionnaire to collect responses from construction professionals. The respondents were selected using a combination of purposive and snowball sampling techniques, resulting in a 75% response rate. Data analysis included mean score value (MSV), standard deviations and normality testing (Shapiro-Wilk) to assess data characteristics. The Kruskal-Wallis H-test was used for further analysis due to the ordinal nature of the data.

The findings of this study indicate that social media can be effectively used in project management, communication, safety management, as well as marketing and branding of AECO projects. The most significant benefits of using social media in construction activities include building trust and credibility, enhancing crisis communication and improving project collaboration.

This study introduces a fresh perspective by showcasing the transformative potential of social media, traditionally viewed as a communication tool, in addressing complex issues in construction project delivery. Consequently, the findings of this study can offer a paradigm shift in the way construction professionals, policymakers and industry stakeholders perceive and harness the capabilities of social media.

Introduction: Interest and action concerning fiscal accountability have surged around the world in recent years, especially among Sub-Saharan African countries, because decision-making in the region has traditionally been shrouded in secrecy, with the general public having almost no access to knowledge on the management of public funds. Limited fiscal transparency has led to government fiscal crises where citizens have begun to call for better governance and participation in public funds.

Purpose: This study examines the impact of e-governance on the overall fiscal performance in SSA, while the specific objectives include the effect of e-governance on the central government’s primary balance and public external debt stock.

Methodology: The study employs annual data across 43 SSA countries to analyse the study from 2000 to 2018 using the panel-corrected standard error (PCSE) method for estimating the models. Overall fiscal performance is generated through principal component analysis (PCA), which involves a linear combination of public external debt stock and central government primary balance.

Findings: The results reveal that there is clear evidence of the effectiveness of e-governance on the overall fiscal performance, even though this is not the same for the public external debt stock in SSA, despite the success recorded in the region’s ICT and telecommunication sectors in recent times. In addition, all other control variables impact fiscal performance except population growth.

Despite the growing use of Fourth Industrial Revolution (4IR) technologies in construction, the reasons behind adopting social media in this context and its real benefits for sustainable construction and productivity remain unclear. This study aims to examine how construction professionals perceive the impact of social media on sustainable construction and productivity in the industry.

This research used a mixed-methods research approach (qualitative and quantitative), resulting in the formulation of a well-structured questionnaire which was distributed to construction professionals. Ordinal regression and multinomial logistic regression were carried out to assess the impact of social media use on sustainable construction and productivity enhancement, as well as the extent of social media utilization in construction projects.

Through exploratory factor analysis, five distinct clusters of social media consequences were identified, namely: information and knowledge sharing, community engagement and morale, environmental and resource management, disruptive and stressful effects and communication and collaboration. Furthermore, the extent of social media usage is closely related to three key factors: community engagement and morale, environmental and resource management and communication and collaboration.

This study represents one of the pioneering research efforts in Nigeria to investigate the implications of social media usage in the construction industry. Thus, future studies can build upon this research to further contribute to the multifaceted dimensions of social media’s impact on the construction industry.

The purpose of this paper is to investigate the relationship between housing finance institutional related variables and financial related variables of low-income earners in Bauchi Local Government Area, Bauchi, Nigeria.

In this study, quantitative research approach was adopted. Self-administered structured questionnaires were used to collect information from 500 primary school teachers in Bauchi Local Government Area, Bauchi, Nigeria. A correlation analysis was carried out to find the relationship between housing finance institutional contexts and finance contexts to low-income earners in the study area using SPSS Version 23 software.

The findings shows that the low-income earners were more concerned with the accessibility and affordability on housing ownership, and it also showed that performance and effectiveness of the housing finance institutions were of paramount importance to housing ownership for the low-income earners in the study area.

The finance institutions are the prime consumer of these research findings. The participants in the finance institutions are going to benefit from the low-income earners’ housing ownership development.

The paper also emphasized that the finance institutions should make the housing finance loan accessible and affordable to the low-income earners to meet their dream to sustainable housing ownership.

Aquaculture insurance has the potential of redressing climate-change because it serves as an alternative source of finance in the event of unforeseen circumstances. To this end, the authors examine the prospects, determinants and profitability of aquaculture insurance among fish farmers in the Eastern region of Ghana.

A total of 140 fish farmers were sampled for the study. Thematic analysis was used to determine perceived aquaculture insurance prospects. The Heckman's two-stage model, profitability index (PI) and return on investment (ROI) was employed to respectively determine the factors influencing aquaculture insurance participation and amount intensity and the profitability of aquaculture.

The thematic analysis revealed three themes on the perception of aquaculture insurance prospects: loss recovery, farm renovation and promotes agriculture. Different sets of demographic and institutional factors have varying influences on aquaculture insurance participation and amount intensity. Profitability index (PI) and return on investment (ROI) were respectively 2.07 and 3.2%.

The research provides relevant information on perceived aquaculture insurance prospects, aquaculture insurance participation, and amount intensity and profitability of aquaculture which can contribute to enhancing aquaculture insurance and the aquaculture industry in Ghana.

Issues pertaining to accessibility and inclusiveness of public spaces are not explicitly discussed in developing nations. Thus, this study aims to explore how ease of access and socio-economic status of residents influence the use of city-centre public spaces in Ibadan, Nigeria.

A survey involving users (N = 427) of three different types of public spaces (shopping mall, park and recreational centre) was undertaken. Statistical analysis including Kruskal Wallis H-test and ordered logistic regression analysis were used in determining the differences in the public spaces attributes and predicting the determinants of use.

The analysis revealed that the use of a private car, income and gender significantly predict the frequency of use. It was observed that the determinants of public space use differ across the three categories. In particular, accessibility better predicted the use of the park than it did for the shopping mall or the recreation club.

It brings to fore ways through which city planning in developing countries can address social exclusion and spatial disparity within city-centres. Specifically, new proposals need to be sensitive to the walkability potentials when sitting parks whilst holistic efforts must be directed towards group-specific needs when planning shopping malls and recreation clubs. City management strategies, policies and incentives are required to encourage the use of public transportation systems within city-centre spaces as it presents a vital platform for improving access and inclusive use.

The study fills the gap in the literature by extending knowledge on certain aspects of city-centre’s public spaces in a unique cultural setting. The implications of socioeconomic disparity on public space use became apparent.
