The main aim of the current study is to investigate the effect of Anti-Crack HP 67/36 glass fibre on the mechanical performance of mortars made of cement, with a focus on post-cracking evaluations using the digital image correlation (DIC) technique.

Experimental tests were carried out on 36-mm long fibres at 0.8% by volume and added to the normal strength (NSM), high strength (HSM) and high strength mortar with fly ash (HSMFA) mortars. CEM I 52.5 CP2 NF, CEM II/A-L 42.5 NF and CEM III/C 32.5 N-SR PM were used for each series of mortar to assess the performance of the glass fibres with the types of cement. F-class fly (FA) ash was used to reduce global CO₂ emissions.

The mortar’s strength decreased as the cement types changed from CEM I to CEM II and III. However, due to changes in the portlandite content of the cement, water porosity increased for both types of mortar, without and with fibre. It was also found that using glass fibre increased flexural strength more than compressive strength, regardless of the type of cement used. For all the strength classes, it was found that the mortar mixes with CEM I had the highest critical crack opening (w_c) and fracture energy (G_F), followed by CEM II and III. No significant effects were observed in the mortar’s property by replacing fly ash (12%).

Only mortars were formulated in this study, but the results must be verified at the concrete scale.

Validation of the DIC technique to characterize the post-cracking behaviour of cement-based material. Use of glass fibres to improve the material’s resistance to cracking.

Use of CEM II and CEM III cements with low CO₂ footprint instead of CEMI without altering the mechanical performance of the material.

The work is a further contribution to studying the cracking behaviour of several series of variable mortars depending on the resistance class and the type of cement used.

This article investigates the dynamic implication of healthcare expenditure on economic growth in the selected ten Sub-Saharan African countries over the period 2000–2018.

The study methodology included dynamic heterogenous panel, using mean group and pooled mean group estimators. The investigation of the healthcare expenditure and economic growth nexus was achieved while controlling the effects of investment, savings, labor force and life expectancy via interaction terms.

The results from linear healthcare expenditure have a significant positive impact on economic growth, while the nonlinear estimates through the interaction terms between healthcare expenditure and investment have a negative statistically significant impact on growth. The marginal effect of healthcare expenditure evaluated at the minimum and maximum level of investment is positive, suggesting the impact of health expenditure on growth does not vary with the level of investments. This result responds to the primary objective of the article.

In policy terms, the impact of investment on healthcare is essential to addressing future health crises. The impact of coronavirus disease 2019 (COVID-19) can never be separated from the shortages or low prioritization of health against other sectors of the economy. The article also provides an insight to policymakers on the demand for policy reform that will boost and make the health sector attractive to both domestic and foreign direct investment.

Given the vulnerability of SSA to the health crisis, there are limited studies to examine this phenomenon and first to address the needed investment priorities to the health sector infrastructure in SSA.

Guided by several pioneered studies, the purpose of this paper is to comprehensively investigate the investment behaviours of Malaysian retail and institutional investors in an attempt to identify whether the influence of psychological biases is equally applicable to investor divides.

The researchers have adopted a quantitative research design by way of survey methodology to obtain data from institutional and retail investors in Malaysia. In addition, the authors have mainly employed second-order measurement invariance analysis to uncover the difference across investor divides.

The tests of measurement invariance at the model level indicate an insignificant difference between institutional investors and retail investors. The post hoc test (at the path level) reveals that institutional and retail investors are similar with respect to representative heuristic, overconfidence bias and anchoring bias; though the results also show that they are different with respect to religious bias and herding bias.

Based on the findings of this study, it is generally not logical to assume that institutional investors completely behave rational during investment decisions. Besides, future researchers are called upon to directly compare the investment decisions of institutional and retail investors with respect to whether the influence of psychological biases is equally applicable to them, particularly on the investigated psychological biases and other psychological biases that are not covered in this study.

This study has offered insight into whether the influence of psychological biases is equally applicable to institutional and retail investors in Malaysia using second-order measurement invariance analysis. This study is unique in context and the approach it has adopted.

The purpose of this paper is to measure the technical efficiency and growth trajectory of Bangladeshi and Indonesian microfinance institutions (MFIs). The motivation for this study was derived from crucial roles that these institutions play in the socio-economic transformation of any nations, especially Bangladesh and Indonesia which are at least prominent in the Asian context in this regard. Rather than “proving” impact, research endeavors have shifted to focusing on “improving” the impact of MFIs, because the ability to improve their impact as socio-economic transformation platform may be hinged on their efficiency over time.

Data were obtained from MIX market database covering a five-year period from 2007 to 2011 for 20 Bangladeshi and 11 Indonesian MFIs. The data obtained were subjected to both efficiency and trajectory analysis using data envelopment analysis (DEA) based on Malmquist productivity index, independent t-test, and latent growth curve modeling (LGCM).

Overall, DEA results indicate that both Bangladeshi and Indonesian MFIs are approximately efficient under constant returns to scale, variable returns to scale, and scale. There has been an improvement in the management practices of Bangladeshi MFIs, while Indonesian MFIs have increased in optimum size. Independent t-test result shows that Bangladeshi MFIs are significantly efficient in terms of performance and firm’s size compared to Indonesian MFIs, but there is no significant difference in their efficiencies with regard to technology. The intercept and the slope of the regression weight in the estimated model using LGCM are not significantly different.

This study measures technical efficiency and growth trajectory of Bangladeshi and Indonesian MFIs over a five-year period. However, future studies could explore this in greater depth by incorporating more data.

The research findings have great implications for the Bangladeshi and Indonesian MFIs. Since this study is among the first of its kind, the researchers have paved ways for further investigation in this area. Moreover, the study encourages the Bangladeshi and Indonesian MFIs to be more concerned of their efficiencies.

This study measures technical efficiency and growth trajectory of the Bangladeshi and Indonesian (MFIs). These have never been examined together in this way before.

The purpose of this paper is to examine the effect of measures to combat Corona Virus Disease 2019 (COVID-19) pandemic on competitiveness in tourism in Nigeria taking strategic dexterity as the moderating variable.

Survey research design approach was used for the study. A total of 235 valid questionnaires gathered from the personnel of ten urban tourist centres in Nigeria were used to examine the goodness of model fit, measurement model and structural correlations between constructs. Partial least squares structural equation modelling approach (PLS-SEM) using Advanced Analysis for Composite (ADANCO 2.2.1) was used to evaluate the hypotheses.

This study finds that travel restriction, boarder closure and strategic dexterity were significant to competitiveness, among which border closures has generated the highest path coefficient. Moreover, the study finds a significant moderating role of strategic dexterity between travel restrictions, border closure and competitiveness. Future studies can reproduce the study by incorporating mediating variables covering the all-tourist centers in Nigeria.

This study might be valuable for tourism-related stakeholders, researchers and policy makers as the result finds indicate strong effect of travel restrictions, border closure on competitiveness of urban tourism. Equally, the study provides new insight as the findings shows a significant moderating role of strategic dexterity between travel restrictions, border closure and competitiveness.

This study is among the few that analyses the effect of measures to combat COVID-19 pandemic on competitiveness in the urban tourism: strategic dexterity as the moderating variables. This study also contributes methodologically through the introduction of PLS-SEM approach.

The purpose of this paper is to examine the adoption of Islamic finance products (murabaha, musharakah, mudarabah, salam, ijara, istisna and Qard Hassan) by small and medium-sized enterprises (SMEs) in Cameroon, a non-Islamic Sub-Saharan African country.

It used primary data collected from a cross-section of 1,358 SMEs in eight regions of Cameroon using self-administered structured questionnaires. To facilitate the analyses and interpretation, these products are grouped into four groups based on certain characteristics. A multivariate probit model is estimated to take into account the interaction between these different Islamic finance products.

This study revealed that the desire to comply with Sharia law, awareness, attitude and intention were critical determinants of the decision to adopt Islamic finance products by Cameroonian SMEs. The least influential factors were perceived behavioral control, subjective norms, enterprise characteristics (size, age and location) and socio-demographic characteristics of the entrepreneur (gender, age and marital status). The extension of the multivariate approach permitted us to compute for predicted probabilities which revealed that there exists a synergy effect between the different Islamic finance products. That is, Cameroonian SMEs combine different Islamic finance products at the same time based on their needs. This is especially the case between the partnership-based products (musharakah and mudarabah) and manufacture/rent products (istisna and ijara).

Policymakers are encouraged to develop stakeholder-oriented strategies to promote effective consumer education in Islamic finance products which will boost awareness. Also, Islamic finance institutions should endeavor to develop innovative financial products that are Sharia-compliant and economically beneficial to the individual and business needs of SMEs. Moreover, policymakers and management of Islamic finance institutions should ensure the putting in place of effective governance structures to guide Islamic finance operations. Finally, policymakers should endeavor to take into account the possible synergy between the different Islamic finance products in their quest to develop this activity.

To the best of the authors’ knowledge, this is the first study that analyses the adoption of different Islamic finance products while taking into account the possible synergy that exists between these products.

This study aims to expand the theory of planned behaviour (TPB) to understand determinants of financial inclusion participation behaviour through the mediating effect of Islamic finance product (IFP) adoption.

A quantitative research design was deployed using primary data from a survey conducted within the Muslim-dominated regions in Nigeria, which was analysed using partial least squares structural equation modelling.

It was found that the original TPB variables, attitude, subjective norms, perceived behavioural control (PBC) and behavioural intention have strong positive influences on financial inclusion participation behaviour, however, among the new variables, government support and IFPs adoption directly influence, while awareness and access to banking and digital channels were not. Furthermore, IFPs adoption significantly mediates the relationship between attitude, behavioural intention, government support and access to banking and digital channels and financial inclusion participation, but it failed to mediate that of subjective norms, PBC and awareness.

These findings imply the need to establish more Islamic financial institutions or conventional banks to introduce IFPs in Muslim-dominated regions in Nigeria, as such products are desirable in expanding financial inclusion. While such is being pursued, policymaking bodies responsible for financial inclusion should design appropriate programmes to create awareness of IFPs for expanding financial inclusion.

To the best of the authors’ knowledge, this study could be the first to expand the TPB by integrating IFP adoption as a mediator within the context of financial inclusion participation as well as the incorporation of awareness, government support and access to banking and digital channels as additional variables.

The aim is to examine the long run and short run linear and non-linear impact of foreign direct investment (FDI) inflows on poverty in Nigeria from 1980 to 2019.

The Augmented Dickey Fuller, Phillips Perron and Kwiatkowski-Phillips-Schmidt-Shin unit root tests and bounds test were used to tests the series stationarity and co-integration, respectively. Autoregressive Distributive Lag (ARDL) and non-linear and linear autoregressive Distributive Lag (NARDL) estimators are employed to examine the long run and short run impact of the coefficients of the variables and diagnostic check.

The study finds that the variables are integrated at a level I(0) and the first difference I(I) and co-integrated. The ARDL estimator indicates that FDI significantly reduces poverty in the long and short run. The findings under NARDL shows FDI positive shock and FDI negative shock reduces poverty substantially in the long-short run, respectively. The error correction term is negative and significant.

This study is limited to a single country (time series) and less informative compared with the panel data study with much informative and free from hetero-scedasticity. Future studies should consider panel data using a similar or dissimilar approach.

FDI inflows stimulate growth, thereby creating job openings, transfer of modern technology and reduce poverty and demonstrate that, if the finding integrated into policy actions, the government would attract FDI inflows for the real sector of the economy.

FDI inflows lead to environmental degradation if inferior technology is use in the host economy, especially the weak environmental regulations in Nigeria.

The authors find no study that applied both ARDL and NARDL estimator, selection of variables measurement and time frame for the study in the context of Nigeria.

In terms of the concept of broken home as a juvenile delinquency risk factor, whilst Nigeria and Ghana are culturally different from western nations (Gyekye, 1996; Hofstede, 1980; Smith, 2004), parental death (PDE) and parental divorce (PDI) have been previously taken-for-granted as one factor, that is ‘broken home’. This paper aims to deconstruct the singular model of ‘broken home’ and propose a binary model – the parental death and parental divorce hypotheses, with unique variables inherent in Nigerian/Ghanaian context.

It principally deploys the application of Goffman’s (1967) theory of stigma, anthropological insights on burial rites and other social facts (Gyekye, 1996; Mazzucato et al., 2006; Smith, 2004) to tease out diversity and complexity of lives across cultures, which specifically represent a binary model of broken home in Nigeria/Ghana. It slightly appraises post-colonial insights on decolonization (Agozino, 2003; Said, 1994) to interrogate both marginalized and mainstream literature.

Thus far, analyses have challenged the homogenization of the concept broken home in existing literature. Qualitatively unlike in the ‘West’, analyses have identified the varying meanings/consequences of parental divorce and parental death in Nigeria/Ghana.

Unlike existing data, this paper has contrasted the differential impacts of parental death and parental divorce with more refined variables (e.g. the sociocultural penalties of divorce such as stigma in terms of parental divorce and other social facts such as burial ceremonies, kinship nurturing, in relation to parental death), which helped to fill in the missing gap in comparative criminology literature.

The purpose of this paper is to examine the socioeconomic determinants of profitability of fresh fish marketing in Ogun State, Nigeria.

The study was a cross-sectional survey of 120 fresh fish marketers selected randomly from four major fish markets in Ado-Odo Local Government area of Ogun State, Nigeria. Data were collected using structured questionnaire which was designed to solicit information on the marketers’ socioeconomic and marketing characteristics, operating costs and returns, and problems associated with fish marketing in the study area. A combination of descriptive statistics, marketing margin, budgetary and ordinary least square regression analyses were employed to analyze the study data.

The study showed that female (85.8 percent) dominated fresh fish marketing. The percent marketing margin of fresh fish was 34.55 percent. The percent marketing investment of 20,906.03, 20,453 per month and 1.43 were realized, respectively. The result of the regression analysis revealed that profit from fresh fish was significantly determined by education, proportion of household members involved in fresh fish marketing, marketers experience, capital, number of sales outlet and purchase price.

The findings was based on information supplied by the fresh fish marketers in the study area based on the authors memory recall since most of the respondents do not have diary where records of activities were kept before the survey.

This study contributes to the existing literature in fish marketing and will provide empirical information to policy makers in the formulation of appropriate policies. It will also serve as a guide to practicing and prospective fresh fish marketers and to researchers who may investigate further into the subject matter.

The social implications from the findings on the return on investment of 1.43 implies that for every one naira invested by fresh fish marketers, a return of 1.43 and a profit of 0.43 were obtained. The study concludes that fresh fish marketing is an economically rewarding and profitable venture in the study area. It also recommends the need to provide credit facilities to finance storage facilities of this group of marketers.

The study is original in nature and revealed the economic status of fresh fish marketing in Ogun State, Nigeria.
