Abstract

Purpose

This paper aims to assess the rate and land category contributing to the changes in seven land-uses in the Kintampo North Municipality of Ghana and the effect of the decisions of land users on future landscapes.

Design/methodology/approach

LANDSAT images were classified to generate land use/cover maps to detect changes that had occurred between 1986 and 2014. In total, 120 farmers were also interviewed to determine their perceptions on land use changes. Interval, category and transition levels of changes were determined. Savanna woodland, settlement and forest were mostly converted to farmland in both intervals (1986-2001 and 2001-2014).

Findings

Results showed that rock outcrop, plantation, cropland and savanna woodland increased at an annual rate of 13.86, 1.57, 0.82 and 0.33 per cent, respectively, whilst forest, settlement and water body decreased at 4.90, 1.84 and 1.17 per cent annual rate of change, respectively. Approximately, 74 per cent of farmers will not change land use in the future, while 84.2 per cent plan to increase farm sizes.

Research limitations/implications

The study shows that more land cover will be targeted for conversion as farmers expand their farmlands. There is the need for strict implementation of appropriate land use/cover policies to sustain food production in the region in this era of changing climate and population increase.

Originality/value

This research assessed the land use changes in the Kintampo North Municipality and its impacts on agriculture and carbon stocks release via land use changes. It identified how the decisions of the local farmers on land management will affect future landscape.

Abstract

Purpose

This paper operationalizes insecurity and governance crises to study their effects on stock market response to two political events in Nigeria – the 2015 and 2019 presidential elections.

Design/methodology/approach

An event study was used to capture the market responses. Abnormal returns at the aggregate and sectoral levels were measured over several time windows before and after the respective election results were announced.

Findings

The market reacted strongly positively to a change in presidency from an incumbent to an opposition party candidate in the 2015 election but weakly positively, at best, to the re-election of the incumbent candidate in the 2019 election. In addition, banking stocks exhibited greater sensitivity to these events than oil and gas stocks.

Research limitations/implications

There may be peculiarities with the Nigerian case and with the two elections analyzed. Therefore, future research could focus on understanding the extent to which the results generalize to the broader sub-Saharan context and other regions that face similar governance challenges.

Practical implications

Understanding that markets may have a different perception towards incumbent versus opposition candidate electoral victories during periods of insecurity and governance crisis is important for investors, policymakers, researchers and the wider society.

Originality/value

Past empirical studies on political events and stock returns in Sub-Saharan Africa contexts such as Nigeria ignore shifts in voter mood and produce contradictory findings. This paper helps to resolve some of these contradictions by providing insight into how the markets can have a different perception towards incumbent and opposition candidate electoral victories during periods of insecurity and governance crisis.

Abstract

Purpose

The coronavirus disease 2019 (COVID-19) pandemic has affected the global economy and, thus, the global construction industry. This paper aims to study the impact of COVID-19 on construction project performance in the United Arab Emirates (UAE).

Design/methodology/approach

This study adopted a qualitative and exploratory approach to investigate the impact of COVID-19 and its policies on project performance in the UAE construction industry in critical areas of the project management body of knowledge (e.g. schedule, cost, resources and contracts). Semi-structured interview questions were asked from ten construction professional to obtain valuable insights into the pandemic’s effects on the UAE construction industry and the effectiveness of policies implemented to rectify the damage and identify the industry’s new normal.

Findings

The findings indicate that the construction industry faced several challenges such as schedule delays, disrupted cashflows, delayed permits, approvals and inspections, travel restrictions, serious health and safety concerns, material and equipment shortages, among others which hindered the timely delivery of construction projects. It also indicates that efforts made by the government institutions and the construction industry of the UAE such as economic support programs, digitization of processes, fee and fine waivers, health facilities, among other statutory relaxations proved effective in supporting the construction industry against the adverse effects of the pandemic.

Research limitations/implications

The research findings are limited to the literature review and ten semi-structured interviews seeking an expert’s opinion from industry professionals working in the UAE construction industry. The research team did not get access to project documents, contracts and project progress reports which may be required to validate the interview findings, and to perform an in-depth analysis quantifying the impact of COVID 19 on construction projects performance, which is a limitation of this research.

Practical implications

The implication is that, owing to the imposed lockdowns and strict precautionary measures to curb the rapid spread of the pandemic, smooth execution of the construction project across the country was affected. The government institutions and stakeholders of the construction projects introduced and implemented various techniques and solutions which effectively handled the implications of the COVID-19 pandemic on the construction industry of the UAE.

Originality/value

This study has identified the challenges faced by the construction industry of the UAE in the context of the management of project schedule, project cost, construction contracts, health and safety of construction employees and other related aspects of the construction projects. This study also identified the techniques and solutions adopted by various public and private institutions of the country and their implications on construction projects. Therefore, this study provides guidelines for policymakers and future research studies alike.

Abstract

Purpose

The revolution brought about by the internet and the World Wide Web has led to the development of numerous e-Tendering systems for public sector tendering that have automated various aspects of the manual tendering processes that are known to experience numerous problems. However, one key area that has not been fully addressed is the automation of the evaluation of public tenders based on group decision-making. This paper presents part of the development of a Web-based e-tendering system called Nigerian Public Sector eTender (NPS-eTender) that automate the evaluation of public sector tenders based on group decision-making.

Design/methodology/approach

The system was developed using object-oriented methodologies. Specifically, Ripple and unified process methodologies were adopted.

Findings

The results of the system validation showed that NPS-eTender has an average rating of 74% with respect to correct and accurate modelling of the existing tendering domain and an average rating of 67.6% with respect to its potential to enhance the proficiency of public sector tendering in Nigeria. Based on the results of the validation, it can be concluded that the automation of the tender evaluation process can lead to a more proficient tendering process.

Originality/value

This research has contributed to the development of an e-Tendering system for the public sector that supports the whole tendering lifecycle including the automation of evaluation of public tenders based on group decision-making.

This paper aims to investigate the effect of presidential elections on stock return volatility in five leading stock markets in sub-Saharan Africa.

Abstract

Purpose

This paper aims to investigate the effect of presidential elections on stock return volatility in five leading stock markets in sub-Saharan Africa.

Design/methodology/approach

This paper uses various criteria to select an appropriate generalized autoregressive conditional heteroscedasticity model to estimate the second moment of the return distribution with the inclusion of pre- and post-presidential election dummy variables that capture the effect of presidential elections on stock market volatility.

Findings

The empirical results show that high pre-election uncertainty increases volatility in the Nairobi Stock Exchange, Stock Exchange of Mauritius and the Nigeria Stock Exchange. Furthermore, the results show that volatility in stock return is reduced 90 days after an election in Nigeria and South Africa but increases 90 days after elections in Ghana.

Originality/value

Contrary to the previous studies that are conducted in a single country with focus on specific elections, this paper provides a comparative analysis of presidential elections and stock return volatility in five leading stock markets in sub-Saharan Africa.

Abstract

Purpose

Technologies have had a positive impact on the construction industry. Technologies such as BIM, automation, augmented and virtual reality, Internet of Things and robotics have been adopted by construction firms to enhance productivity. However, not much research has been done on the awareness and adoption of wearable technologies for health and safety (H&S) management. This paper investigates the level of awareness and adoption of wearable technologies for H&S management in the Nigerian construction industry.

Design/methodology/approach

A quantitative research method was adopted for the study. An electronic questionnaire format was used as an instrument to collect the data. Both descriptive (mean score) and inferential statistics (Kruskal–Wallis test) were used to analyse the data.

Findings

The results indicate that organisations rarely use H&S wearable devices for H&S management although professionals within the construction industry are somewhat aware of the common H&S wearable devices. The findings further indicate that all 11 variables were perceived as “rarely adopted”, whereas 2 variables were perceived as “aware”, 3 variables as “slightly aware” and the remaining 6 variables as “somewhat aware”.

Research limitations/implications

Data were collected from only construction professionals working in government agencies, consultancy firms and grade D contracting firms in Lagos and Abuja. For a broader perspective, a study that expands the number of states and categories of construction firms is recommended.

Practical implications

The construction industry in Nigeria can use the recommendations to improve H&S management on site. Moreover, the recommendations can contribute to the development of policies to promote the adoption of wearable technologies in construction sites.

Originality/value

Research on wearable technologies, particularly in the Nigerian construction industry, is at the developing stage. With this article, the authors contribute to the body of knowledge in this area of research.

This study aims to develop a building renovation duration prediction model incorporating both scope and non-scope factors.

Abstract

Purpose

This study aims to develop a building renovation duration prediction model incorporating both scope and non-scope factors.

Design/methodology/approach

The study used a questionnaire to obtain basic information relating to identified project scope factors as well as information relating to the impact of the non-scope factors on the duration of building renovation projects. The study retrieved 121 completed questionnaires from construction firms on tertiary education trust fund (TETFund) building renovation projects. Artificial neural network was then used to develop the model using 90% of the data, while mean absolute percentage error was used to validate the model using the remaining 10% of the data.

Findings

Two artificial neural network models were developed – a multilayer perceptron (MLP) and a radial basis function (RBF) model. The accuracy of the models was 86% and 80%, respectively. The developed models’ predictions were not statistically different from those of actual duration estimates with less than 20% error margin. Also, the study found that MLP models are more accurate than RBF models.

Research limitations/implications

The developed models are only applicable to projects that suit the characteristics and nature of the data used to develop the models. Hence, models can only predict the duration of building renovation projects.

Practical implications

The developed models are expected to serve as a tool for realistic estimation of the duration of building renovation projects and thus, help construction project managers to effectively plan and manage it.

Social implications

The developed models are expected to serve as a tool for realistic estimation of the duration of building renovation projects and thus, help construction project managers to effectively plan and manage it; it also helps clients to effectively benchmark projects duration and contractors to accurately estimate duration at tendering stage.

Originality/value

The study presents models that combine both scope and non-scope factors in predicting the duration of building renovation projects so as to ensure more realistic predictions.

Abstract

Purpose

The purpose of this paper is to investigate the effect of talent management (TM) practices on employee performance (EP) and to explore the mediating role of employee engagement (EE) on the relationship between TM practices and EP in Malaysian private universities (MPUs).

Design/methodology/approach

The paper used both descriptive and quantitative approaches, and the unit of analysis of this research consists of MPUs academic staff. The research sample consists of 314 MPUs academic staff, and a questionnaire was used to collect data from the target respondents, while partial least squares-structural equation modelling was used to evaluate the study hypotheses through bootstrapping approach.

Findings

The research outcome revealed that TM practices that comprise of talent recruitment practice (TRP), training and development practice (T&DP), compensation practice (CP) have a significant effect on EP. Furthermore, EE partially mediates the relationship between T&DP, CP and EP, while EE does not mediate the relationship between TRP and EP in MPUs.

Practical implications

The research suggests that universities management should focus on TM practices as a tool to achieve and maintain EE and positive attitudes (EP) in relation to work.

Originality/value

The research makes substantial contributions to the literature by investigating the effect of TM practices on EP through the role of EE as mediation in MPUs. The research is one of the very few studies undertaken in MPUs. Therefore, the results of this research serve as a guide for the universities management to develop their institutional strategies and policies in a manner in which their employees’ success can be achieved and encouraged.International Journal of Business and Society.

Abstract

Purpose

The global economic crisis triggered by the coronavirus disease 2019 (COVID-19) has caused the closure of countless ethnic minority businesses (EMBs) worldwide, partly due to the public policy responses. This paper investigates whether EMBs’ entrepreneurial orientation (EO) mediates the impact of public policy responses to COVID-19 on their survival.

Design/methodology/approach

Utilizing institutional theory, the authors developed a novel conceptual framework that divides policy responses to COVID-19 into aggressive (imposing restrictions on movement, e.g. lockdowns) and less aggressive policy responses (not imposing restrictions on movement, e.g. social distancing). The authors then surveyed intra-regional EMBs, specifically businesses owned by ethnic minorities in the Kano and Katsina provinces of Nigeria, and analysed the data using structural equation modelling and analysis of variance (ANOVA).

Findings

The authors found that intra-regional EMBs in developing countries are very vulnerable to the public policy responses imposed by governments to curb COVID-19. Aggressive policy responses have a more significant negative effect on the survival of intra-regional EMBs than their less aggressive counterparts. Furthermore, the authors found that EO as a crisis response strategy significantly supports intra-regional EMBs in managing their vulnerability to the hostile institutional environment, reduces the adverse effect of public policy responses and stimulates their survival during the COVID-19 pandemic.

Originality/value

This paper contributes to the institutional theory of small and medium-sized enterprises (SMEs)/entrepreneurship and the literature on EMBs by showing the role of EO in mediating the effects of COVID-19 institutional policies on the survival of intra-regional EMBs.

Abstract

The white buildings of Ahmadu Bello University lie between the A.19 Zaria‐Funtua road and a small river that runs, deeply trenched in red laterite, through the surrounding scrubland. For much of the year this “river” is a spruit of water no more than a foot wide and two inches deep—it is only in electric storms that it hisses as a torrent between the laterite banks—nevertheless, it may be taken as a pledge, at all times of the year, that sufficient subterranean water may be pumped out of the sands of the river‐bed to meet the needs of the University. The large blocks of buildings, in modern concrete idiom, look as if they have been torn from a city and dropped upon this open scrubland.
