Abstract

Purpose

The purpose of this study is to investigate the effect of the incorporated zirconia (ZrO2) nanoparticles on the performance of the deposited layer Ni–Cu alloy on steel sheet.

Design/methodology/approach

The aim was to produce Ni–Cu–ZrO2 nanocomposite coatings by electrodeposition technique and estimate the influence of ZrO2 nanoparticles on the performance of Ni–Cu alloy. The surface morphologies and chemical compositions of the deposited layers were assessed using scanning electron microscopy and energy-dispersive X-ray analysis, respectively. Nanoindentation was used as a well-advanced technique for measuring microhardness and Young’s modulus values of different coatings. The corrosion resistance in 3.5 per cent NaCl solution of electrodeposited films has been investigated.

Findings

The main conclusion is that the surface morphologies of Ni–Cu–ZrO2 nanocomposite coatings were fine granular compared with Ni–Cu alloy. The corrosion behavior illustrated that the incorporation of ZrO2 nanoparticles with Ni–Cu film improved the corrosion resistance. Significant improvement was also demonstrated in the hardness of nanocomposite coatings.

Social implications

The optimized industrial use of steel-coated Ni–Cu alloy with super properties. Consequently, a social benefit can be associated with the reduction in the corrosion rate and increases the microhardness and Young’s modulus.

Originality/value

The results presented in this work are an insight into understanding the incorporation of ceramic reinforcement with metal or alloy films (matrix) on carbon steel using the electrodeposition technique. The development of corrosion resistance of Ni–Cu alloys has been considered as a promising behavior. In this work, a consistent assessment of the results achieved on laboratory scale has been conducted.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.

Abstract

Purpose

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.

Design/methodology/approach

This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.

Findings

This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.

Originality/value

This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.

Abstract

Purpose

The present study tries to examine the relationship between financial inclusion and environmental quality as proxied by carbon emissions in India covering the period from 2008 to 2018.

Design/methodology/approach

A financial inclusion index has been composed using principal component analysis (PCA) based on three dimensions: access, penetration and usage. After testing for stationarity of the data, the authors adopted the autoregressive distributive lag model (ARDL) methodology.

Findings

The study found that financial inclusion and growth lead to increased carbon emissions in India and the government must resort to greener policies, whereas empirical results support that globalization reduced the pollutants emissions in both the long term and short period in India.

Practical implications

Based on the results, several policy prescriptions are rendered for policymakers: (1) need to move toward greener energy policies and (2) enhance the awareness of green financing instruments such as green bonds in India. Therefore, policymakers should be more proactive in accepting green and sustainable financial alternatives.

Originality/value

The present study contributes to the scant literature on the financial inclusion–emission nexus in India. This study considers three inclusion parameters that are not present in previous studies.

Abstract

Purpose

This study aims to investigate the impact of empowering leadership (EL) on employee innovative work behavior (IWB), using an interactionist perspective on creativity and conservation of resources theory. Following the premise, the study unravels the mediating role of job crafting (JC) and creative self-efficacy (CSE) as a boundary condition that likely triggers and facilitates this process.

Design/methodology/approach

Using a dyadic cross-sectional design, this study focuses on academic staff at four universities in Pakistan. Participants were surveyed, and questionnaires were distributed to collect data pertaining to accomplish the study objectives.

Findings

The study results reveal that JC plays a pivotal role as an intervening factor in establishing the connection between EL and employees’ IWB. This implies that EL likely promotes employees’ JC behavior, thus contributing to a greater manifestation of innovative behaviors at work. Furthermore, this interplay is further enhanced by using CSE as a moderator.

Originality/value

This study accentuates the importance of JC in eliciting the mechanism which effectively channelizes and translates the impact of EL on IWB. It also offers the valuable and fresh perspective on the conditions favoring the innovative behaviors at work.

Abstract

Purpose

Financial inclusion policy focuses on bringing the less privileged groups into the formal financial system. Financial inclusion has a lot of benefits in the society. It can reduce the level of poverty, inequality and encourage business startup. This study aims to examine the impact of financial inclusion on entrepreneurship in selected African countries.

Design/methodology/approach

This paper examines how financial inclusion impacts entrepreneurship in 13 selected African countries using data from World Bank Development Indicators, IMF’s International Financial Statistics, doing business and World Bank Entrepreneurship Survey for the period of 2005-2016. It uses panel data regression techniques such as random effect, IV estimation and robust least square.

Findings

The results show that financial inclusion has a significant and positive effect on entrepreneurship in Africa. This result is robust to both alternative measures of financial inclusion and alternative estimators.

Originality/value

The possible relationship between financial inclusion and entrepreneurial development has been an ongoing debate in other developing countries. However, this issue has been neglected in the African region. There are little or no evidence to support the possible relationship in Africa. This paper makes an important contribution in this respect and further provides insightful information in the ongoing debate.

Abstract

Purpose

Surface roughness has a serious impact on the fatigue strength, wear resistance and life of mechanical products. Realizing the evolution of surface quality through theoretical modeling takes a lot of effort. To predict the surface roughness of milling processing, this paper aims to construct a neural network based on deep learning and data augmentation.

Design/methodology/approach

This study proposes a method consisting of three steps. Firstly, the machine tool multisource data acquisition platform is established, which combines sensor monitoring with machine tool communication to collect processing signals. Secondly, the feature parameters are extracted to reduce the interference and improve the model generalization ability. Thirdly, for different expectations, the parameters of the deep belief network (DBN) model are optimized by the tent-SSA algorithm to achieve more accurate roughness classification and regression prediction.

Findings

The adaptive synthetic sampling (ADASYN) algorithm can improve the classification prediction accuracy of DBN from 80.67% to 94.23%. After the DBN parameters were optimized by Tent-SSA, the roughness prediction accuracy was significantly improved. For the classification model, the prediction accuracy is improved by 5.77% based on ADASYN optimization. For regression models, different objective functions can be set according to production requirements, such as root-mean-square error (RMSE) or MaxAE, and the error is reduced by more than 40% compared to the original model.

Originality/value

A roughness prediction model based on multiple monitoring signals is proposed, which reduces the dependence on the acquisition of environmental variables and enhances the model's applicability. Furthermore, with the ADASYN algorithm, the Tent-SSA intelligent optimization algorithm is introduced to optimize the hyperparameters of the DBN model and improve the optimization performance.

Abstract

The aim of this chapter is to examine the role of real exchange rates in the relationship between tourist arrival and economic growth in Malaysia over the period of 2000–2018. We disaggregate Malaysian tourists into six geographical regions, namely Asia, Singapore, Europe, Pacific region, Americas, and Africa. Using a non-linear autoregressive distributed lag model, we find that the appreciation of real exchange rates with positive growth of economy plays a prominent role in influencing international tourist arrivals from Singapore, other Asian countries, Pacific region, Europe, and Americas. Our study suggests that real appreciation is important in providing some insights into the effectiveness of growth-led-tourism policies. In line with this, some implications are provided at the end of this chapter.

Abstract

Purpose

The relationships between transformational leadership (TL), organizational climate (OC) and project performance have been investigated by previous studies, but no review of existing studies has systematically analyzed the effects of TL and OC on project performance in the industrial revolution (IR) 5.0 era. Therefore, this study aims to conduct a systematic literature review on the effects of TL and OC on project performance in IR 5.0, and to identify mainstream research topics, research gaps and future research directions.

Design/methodology/approach

To do this, a total of 53 included journal articles were obtained after initially retrieving 648 documents from the Scopus database by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. It consists of four main steps, namely, identification of documents, screening, eligibility and included articles. In addition, science mapping analyses were conducted for keyword co-occurrence and document analyses, which aided in identifying the mainstream research topics, research gaps and future research directions.

Findings

The results report the annual publication trends, keywords and document analyses. Furthermore, a detailed qualitative discussion highlighted four mainstream research topics including TL in project management; the relationship between TL, OC and innovation; safety climate; and OC in project management. Moreover, this review study identified four research gaps and future research directions aligned with the mainstream research topics. They include: longitudinal investigations and multinational corporation surveys in TL; scope and longitudinal data in innovation; mono-method bias and universality of safety climate; and more comprehensive analyses of OC.

Originality/value

This review study would contribute to not only advancing the effects of TL and OC on project performance in IR 5.0, but also enabling project managers to understand TL or OC issues to improve project performance.

Abstract

Purpose

The purpose of this paper is to integrate job demands–resources theory with core self-evaluation theory to examine how and when sustainable project leadership stimulates sustainable project performance. Psychological empowerment is used as a mechanism between sustainable project leadership and sustainable project performance, whereas core self-evaluation acts as a moderator between sustainable project leadership and psychological empowerment.

Design/methodology/approach

This study adopts a time-lagged two-phase approach to collecting data from 257 software engineers working in medium-sized and large companies in the Polish financial sector.

Findings

This study reveals the direct and indirect (through psychological empowerment) effects of sustainable project leadership on sustainable project performance. It also confirms that the “sustainable project leadership–psychological empowerment” relationship strengthens with increasing level of project team members’ core self-evaluation.

Originality/value

This article explores a unique research framework. It significantly enriches the literature on sustainable project management, increasing the understanding of effective leadership practices that address the needs of software engineering teams to support sustainable project performance.

Abstract

Purpose

The construction of infrastructure projects for extracting natural resources is vital to the economies of countries and the strategies of mining companies. Project performance success (PJPF) means achieving the planned scope, cost, schedule and quality. This study aims to analyze if PJPF is influenced by the team’s psychological empowerment (PEMP) and structural empowerment (SEMP), the project manager’s transformational leadership (TLD) and shared leadership (SLD) styles and the cultural power distance (CPDT). The study also examined the mediating roles of TLD and CPDT.

Design/methodology/approach

This paper tested its hypotheses through confirmatory factor analysis and structural equation modeling in AMOS. Data were collected using the online survey platform SurveyMonkey. Owners, contractors and consultants from 24 countries across the Americas, Africa, Europe, Asia and Australia contributed a total of 222 responses. All participants were involved in construction projects owned by a mining company listed in the S&P 500.

Findings

PEMP has a positive impact on PJPF, SEMP and CPDT. PEMP fosters engaged and autonomous employees with agility and problem-solving skills. TLD mediates the relationship between PEMP and SLD. The results indicated that SEMP, TLD and SLD, on their own, do not directly contribute to project success. In contrast to prior studies, CPDT does not mediate the effects of PEMP on PJPF.

Originality/value

Although construction projects remain labor-intensive, research on measuring PEMP, SEMP, TLD, SLD and CPDT in this field is limited. This document is notable for incorporating the perspectives of owners, EPC contractors and consultants.
