Abstract

Purpose

The purpose of this paper is to investigate the applicability of cloud computing (CC) and the challenges that contribute to more successful projects with a major sustainable construction development.

Design/methodology/approach

The previous studies provided information on CC implementation barriers, which were then evaluated by 104 construction stakeholders through a questionnaire survey. As a result, the exploratory factor analysis (EFA) approach was used to investigate these barriers. Furthermore, a partial least square structural equation model was used to build a model of these barriers (PLS-SEM).

Findings

The EFA results revealed that the above-noted factors are in a close relation with three key components, i.e. social, economic and communication. In addition, the proposed model results found the social barrier a key challenge to the implementation of CC.

Research limitations/implications

The results from this study can help decision-makers to improve the approaches regarding data fragmentation that has great effects on the execution of all construction projects. The focus of the paper is to enhance the data fragmentation processes. In addition, the results would be useful to strengthen the sustainability of existing construction projects by enhancing the implementation of CC.

Originality/value

The novelty of this research work will provide a solid foundation for critically assessing and appreciating the different barriers affecting the adoption of CC.

Abstract

Purpose

Cloud computing is one of the digitalization principles used in some sectors like banking, health and construction industry. This paper aims to examine the benefits of applying cloud computing for construction sustainability in Nigeria.

Design/methodology/approach

The cloud computing benefits-related data were retrieved from previous studies and complemented with a questionnaire survey to obtain data from stakeholders involved in the execution of construction projects in Lagos State, Nigeria, through a convenient sampling technique. In addition, the relative importance index (RII) technique was used to investigate the acquired data. At the same time, analysis was accomplished using exploratory factor analysis (EFA). Findings indicated that numerous benefits could be derived by adopting cloud computing in the Nigerian construction industry.

Findings

The findings from RII analysis showed the significant benefits of data storage ubiquity (i.e. location independence), high situational awareness, team collaboration, compatibility with advanced production facilities and improved project planning. Furthermore, the analysis of these benefits was conducted using EFA for the four construction maxims: construction productivity, back-office activities, design management and billing.

Originality/value

This research illustrated the benefits of cloud computing in achieving a successful construction project. Besides, these findings are not only useful for achieving sustainable construction in Nigeria but also applicable to many developing countries.

Abstract

Purpose

The purpose of this paper is to assess the cloud computing (CC) methods and tools towards the achievement of construction project sustainability in Nigeria.

Design/methodology/approach

Data were obtained from the literature, complemented by a quantitative method using a questionnaire distributed among 104 respondents comprising mainly construction professionals in Nigeria. Subsequently, data were analysed using the exploratory factor analysis (EFA) method. In addition, the partial least square structural modelling was used to generate a model for the adoption of CC tools for sustainable construction.

Findings

EFA results indicated that the CC implementation tools could be categorised into four significant constructs: platform, communication, software and data storage. Results obtained from the model showed that platform tools were the most crucial tools for implementing CC in the construction industry.

Practical implications

The findings from this study are essential to the pursuit of perception of methods and tools connected to the vagueness of CC for future employees. In addition, the identified CC tools are expected to enhance the success of construction projects.

Originality/value

The novelty of this research work will be a benchmark or board for decision-makers to quality by adopting CC methods and tools in Nigeria’s construction projects to achieve their sustainable projects.

Abstract

Purpose

During the coronavirus (COVID-19) pandemic lockdowns, stay at home or work from home, many have argued that the westernised non-pharmaceutical interventions (NPI) do not provide remedial in low-income countries like Nigeria, where informal job seekers, street traders, informal labourers and artisans depend mainly on the informal economy. By applying social solidarity (SS) and community-based approach (CBA), the authors evaluate individual acts (trust, altruism and reciprocity) during the lockdown and how these practices evolve from individual approaches to collective actions.

Design/methodology/approach

This study reflects on pragmatism research paradigm that enables researchers to maintain both subjectivity in their reflections and objectivity in data collection and analysis. The authors adopt a qualitative method through purposeful and convenience sampling procedure. Data were analysed thematically to identify elements of SS, individual acts, collective or community actions and perceptions.

Findings

The findings reveal that COVID-19 had a disproportionate impact (lack of food and a fall in daily income) on workers, informal job seekers, informal businesses operators and the poor households. As such, the study developed a reflective model of solidarity exhibited by individual acts and collective acts (practices of resource pooling, information sharing, women empowerment, distribution of palliatives and donations) within trusted circles that helped people cope with the lockdown experiences.

Practical implications

Solidarity represents beliefs, practices of values and norms. The SS exhibited by people through NPI would have implications on planning and monitoring the effectiveness of public health programmes during a pandemic in the future.

Social implications

The findings of citizens and community actions have implications related to the process of building communities – coming together – and solidarity that enhances social development with implications on community health policy agenda during disasters, emergencies and health pandemic.

Originality/value

This is one of the first studies to analyse the relationship between trust, altruism, reciprocity, SS and CBA during the COVID-19 pandemic. Also, it seems reasonable to clarify the concept of SS given the lack of clarity about the definitions from previous studies.

Abstract

Purpose

This study aims to assess financial development and debt status impact on energy efficiency in Nigeria as a developing economy.

Design/methodology/approach

This study combined the autoregressive distributed lag (ARDL), fully modified ordinary least squares and canonical cointegration regression analytical methods to estimate the parameters for energy efficiency policy recommendations. Secondary data between 1990 and 2020 were used for the analysis.

Findings

The result confirms the long-run nexus between energy efficiency, financial development and total debt stock. Furthermore, the ARDL estimates for this study’s key variables show that financial development promotes energy efficiency in the short run but hinders long-run energy efficiency. Total debt stock limits energy efficiency in Nigeria in short- and long-run periods.

Research limitations/implications

The limitation of this study is that the scope is limited to Nigeria as a developing economy. The need to support energy efficiency projects is a global call requiring cross-country analysis. Despite this study’s focus on Nigeria, it provides useful insights that can guide energy efficiency policy through the financial sector and debt management.

Practical implications

The financial sector must ensure the availability of long-term credit facilities to clean energy investors. The government must maintain a sustainable debt profile to pave the way for capital expenditure on clean energy projects that promote energy efficiency.

Originality/value

The environmental consequences of energy intensity are being felt globally, with the developing countries most vulnerable. The cheapest way to curb these consequences is to promote energy efficiency to reduce the disastrous effect. Driving energy efficiency requires investment in energy-efficient technology but the challenge for developing economies, i.e. Nigeria’s funding, remains challenging amid a blotted debt profile. This becomes crucial to investigate how financial sector development and debt management can accelerate energy-efficient investments in Nigeria.

Abstract

A Casebook of Indigenous Business Practices in Africa is a collection of business case studies that expand understanding of how indigenous enterprises apply entrepreneurial practices embedded in culture to achieve success. Indigenous methods are part of Africa's social and economic fabric, and these cases identify concepts and models that can accelerate growth in Africa. The value of these practices across regions of Africa cannot be overemphasised despite the dominance of Western business methods, which, though beneficial, are yet to drive the continent's developmental agenda. By exploring indigenous business practices in Africa, students, educators, practitioners, entrepreneurs and government decision-makers will be introduced to unique and sustainable practices that can foster inclusive growth and social and economic empowerment when contextualised within the business landscape. Identification of relevant orientations in indigenous practices that will benefit contemporary business frameworks and actors is a significant contribution of the authors of this book. Incorporation of these indigenous methods into management teachings and business practices is essential to the continent's economic growth and socio-cultural progress.

Abstract

Purpose

This study aims to investigate the effect of Ajuga iva (Ai) on enzymes involved in the metabolism of cholesterol, in rat fed a cholesterol-enriched diet.

Design/methodology/approach

Male Wistar rats (n =12), weighing 120 ± 5 g were fed on 1 per cent cholesterol-enriched diet [hypercholesterolemic (HC)] for 15 days (d15). After this adaptation phase, HC rats (total cholesterol = 6.5 ± 0.6 mmol/L) were divided into two groups fed the same diet and treated (Ai-HC) or not with (HC) with Ai for d15.

Findings

At day 15, in Ai-HC group compared to HC, serum triacylglycerol (TG) values were 1.4-fold lower (p =0.002), whereas unesterified cholesterol (UC) contents were 1.8-fold higher (p =0.0001). Serum phospholipids (PL) and cholesteryl esters (CE) contents and liver TG, UC, PL and CE values were not sensitive to Ai. TC/HDL-C and LDL-HDL1-C/HDL-C ratios were, respectively, 1.8- and 4-fold lower (p =0.006 and p =0.04). HDL2-C and HDL3-C amounts were enhanced by 40 and 74 per cent, respectively (p =0.003 and p =0.0001). HDL3-UC was 1.6-fold higher (p =0.006); whereas PL contents were 1.4-fold lower (p =0.003). HDL3-apo and HDL2-CE contents were similar between groups. A decreased of hydroxy-methyl-glutaryl-coenzyme A reductase and cholesterol 7α-hydroxylase activities (−44 and −25 per cent; p =0.003 and p =0.02, respectively) were noted. Lecithin: cholesterol acyltransferase activity was 1.5-fold higher (p =0.001).

Originality/value

In HC rat, Ai is able to induce hypotriglyceridemia. However, it turns out that Ai may reduce cardiovascular risk by decreasing the reports of atherogenicity and modifying the activities of enzymes involved in the cholesterol metabolism.
