Abstract

Purpose

This study aims to investigate female commercial drivers in the Lagos metropolis. The study sought to know the circumstances that motivated women to venture into commercial driving; the experiences they encounter whilst engaging with other stakeholders in the public space; the dimension of the conflict between work and family, and the coping strategies used and finally, the health concerns of female commercial drivers.

Design/methodology/approach

The study adopted a cross-sectional design and a qualitative method of data collection. An in-depth interview guide was used to elicit information from 18 female drivers drawn from three sectors of commercial transportation in Lagos State.

Findings

It was found that the major motivation for engaging in commercial driving is the need for survival and family support; although participants acknowledged that they cannot be in the profession for a long time. Married women had less time to engage in commercial driving due to other family responsibilities. Women drivers have experienced mixed reactions from other road users. Commercial driving is physically demanding and poses threat to the health of female commercial drivers.

Originality/value

The findings highlight the circumstances behind women participating in commercial driving. Despite the challenges encountered in this course of this activity, they are still bent on continuing because of the need to take care of their children, a majority of their spouses are not fully contributing to the maintenance of the home.

Abstract

Purpose

This paper aims to explore the drivers of sustainable healthcare supply chain (SHCSC) performance measurement through extensive literature review and experts' opinions. The drivers are then scrutinized and their priority vector is calculated to provide quality and cost-effective healthcare supply chain (HCSC) services.

Design/methodology/approach

The drivers of the SHCSC performance measurement are validated using the grey-Delphi technique. After validating the drivers, they are prioritized using the grey-analytic hierarchy process (G-AHP), a multi-criteria decision-making tool.

Findings

The findings of the study highlight the prioritized drivers based on the preferences given by the experts. The findings of the study highlight the most prioritized drivers of healthcare (HC) by-product management system, coordinating and facilitating green suppliers in the HCSC and green packaging of pharmaceutical as well as other essential items.

Practical implications

The HCSC managers should coordinate with all the stakeholders across the supply chain and involve them in the decision-making process to make products and services greener and become complicit in complying with the sustainable policy guidelines. The study highlights the strategic policy and managerial implications for implementing sustainability in the HCSC.

Originality/value

The validation and prioritization of the drivers of SHCSC in developing nations' contexts is the key contribution of the study. Grey-AHP enables a practical approach towards enhancing the sustainability of the HCSC and opening the doors for generalizing the study for future research works.

Abstract

Purpose

The anticipated benefits of connected and autonomous vehicles (CAVs) include safety and mobility enhancement. Small headways between successive vehicles, on one hand, can cause increased capacity and throughput and thereby improve overall mobility. On the other hand, small headways can cause vehicle occupant discomfort and unsafety. Therefore, in a CAV environment, it is important to determine appropriate headways that offer a good balance between mobility and user safety/comfort.

Design/methodology/approach

In addressing this research question, this study carried out a pilot experiment using a driving simulator equipped with a Level-3 automated driving system, to measure the threshold headways. The Method of Constant Stimuli (MCS) procedure was modified to enable the estimation of two comfort thresholds. The participants (drivers) were placed in three categories (“Cautious,” “Neutral” and “Confident”) and 250 driving tests were carried out for each category. Probit analysis was then used to estimate the threshold headways that differentiate drivers' discomfort and their intention to re-engage the driving tasks.

Findings

The results indicate that “Cautious” drivers tend to be more sensitive to the decrease in headways, and therefore exhibit greater propensity to deactivate the automated driving mode under a longer headway relative to other driver groups. Also, there seems to exist no driver discomfort when the CAV maintains headway up to 5%–9% shorter than the headways they typically adopt. Further reduction in headways tends to cause discomfort to drivers and trigger take over control maneuver.

Research limitations/implications

In future studies, the number of observations could be increased further.

Practical implications

The study findings can help guide specification of user-friendly headways specified in the algorithms used for CAV control, by vehicle manufacturers and technology companies. By measuring and learning from a human driver's perception, AV manufacturers can produce personalized AVs to suit the user's preferences regarding headway. Also, the identified headway thresholds could be applied by practitioners and researchers to update highway lane capacities and passenger-car-equivalents in the autonomous mobility era.

Originality/value

The study represents a pioneering effort and preliminary pilot driving simulator experiment to assess the tradeoffs between comfortable headways versus mobility-enhancing headways in an automated driving environment.

Abstract

Purpose

The purpose of this paper is to deal with the practical challenge faced by modern logistics enterprises to accurately evaluate driving performance with high computational efficiency under the disturbance of road smoothness and to identify significantly associated performance influence factors.

Design/methodology/approach

The authors cooperate with a logistics server (G7) and establish a driving grading system by constructing real-time inertial navigation data-enabled indicators for both driving behaviour (times of aggressive speed change and times of lane change) and road smoothness (average speed and average vibration times of the vehicle body).

Findings

The developed driving grading system demonstrates highly accurate evaluations in practical use. Data analytics on the constructed indicators prove the significances of both driving behaviour heterogeneity and the road smoothness effect on objective driving grading. The methodologies are validated with real-life tests on different types of vehicles, and are confirmed to be quite effective in practical tests with 95% accuracy according to prior benchmarks. Data analytics based on the grading system validate the hypotheses of the driving fatigue effect, daily traffic periods impact and transition effect. In addition, the authors empirically distinguish the impact strength of external factors (driving time, rainfall and humidity, wind speed, and air quality) on driving performance.

Practical implications

This study has good potential for providing objective driving grading as required by the modern logistics industry to improve transparent management efficiency with real-time vehicle data.

Originality/value

This study contributes to the existing research by comprehensively measuring both road smoothness and driving performance in the driving grading system in the modern logistics industry.

Abstract

Purpose

Drawing on ego depletion theory, this study aims to provide insights into the effect of work-family conflict on the high-speed railway (HSR) drivers’ safety performance by examining the mediating role of ego depletion and the moderating roles of work-family centrality and supervisor safety support.

Design/methodology/approach

In total, 243 HSR drivers from 7 railway bureaus in China were surveyed. Structural equation modeling was used to test the hypotheses.

Findings

Both work-to-family conflict and family-to-work conflict have direct and positive effects on HSR drivers’ ego depletion and indirect effects on both safety compliance and safety participation via ego depletion. Moreover, both the direct effect of work-family conflict on ego depletion and its indirect effect on safety performance are moderated by work-family centrality. Supervisor safety support plays a buffering role in the relationship between ego depletion and safety performance.

Originality/value

This study examined the relationship between work-family conflict and safety performance based on the perspective of ego depletion theory. The findings testify to the importance of reducing work-family conflict among HSR drivers pursuant to maximizing safety.

Abstract

Purpose

This study aims to analyze driver risks in the driving environment. A complete analysis of context aware assistive driving techniques. Context awareness in assistive driving by probabilistic modeling techniques. Advanced techniques using Spatio-temporal techniques, computer vision and deep learning techniques.

Design/methodology/approach

Autonomous vehicles have been aimed to increase driver safety by introducing vehicle control from the driver to Advanced Driver Assistance Systems (ADAS). The core objective of these systems is to cut down on road accidents by helping the user in various ways. Early anticipation of a particular action would give a prior benefit to the driver to successfully handle the dangers on the road. In this paper, the advancements that have taken place in the use of multi-modal machine learning for assistive driving systems are surveyed. The aim is to help elucidate the recent progress and techniques in the field while also identifying the scope for further research and improvement. The authors take an overview of context-aware driver assistance systems that alert drivers in case of maneuvers by taking advantage of multi-modal human processing to better safety and drivability.

Findings

There has been a huge improvement and investment in ADAS being a key concept for road safety. In such applications, data is processed and information is extracted from multiple data sources, thus requiring training of machine learning algorithms in a multi-modal style. The domain is fast gaining traction owing to its applications across multiple disciplines with crucial gains.

Research limitations/implications

The research is focused on deep learning and computer vision-based techniques to generate a context for assistive driving and it would definitely adopt by the ADAS manufacturers.

Social implications

As context-aware assistive driving would work in real-time and it would save the lives of many drivers, pedestrians.

Originality/value

This paper provides an understanding of context-aware deep learning frameworks for assistive driving. The research is mainly focused on deep learning and computer vision-based techniques to generate a context for assistive driving. It incorporates the latest state-of-the-art techniques using suitable driving context and the driver is alerted. Many automobile manufacturing companies and researchers would refer to this study for their enhancements.

Abstract

Purpose

The detrimental impacts of the construction industry activities, namely, toxicity of cement and concrete to the health of construction workers and the general public, have been reported in previous studies. Several environmental management measures were put in place by international organisations to reduce these impacts on humans and the entire ecosystem. Sadly, such environmental management measures are not widely embraced in the construction industry of developing countries. This contributes to the poor quality of life of construction stakeholders, amongst other outcomes. Therefore, this study investigated the drivers to facilitate an environmental management system (EMS) in the Nigerian construction industry (NCI).

Design/methodology/approach

questionnaires retrieved from construction professionals in the micro, small, medium and large enterprises were used to conduct both descriptive and inferential statistics, namely, mean score, standard deviation, Kruskal–Wallis H test, post hoc test and factor analysis.

Findings

The analyses show that the drivers of EMS implementation in the NCI could be grouped into intellectual enhancement strategies, documentation and cultural strategies, and motivation and tracking strategies. The study concluded that training and education of relevant stakeholders, tracking compliance levels of organisations and recognising firms acting in compliance with stipulated “environmental” policy are essential. It was recommended that the collaboration of all construction stakeholders be upheld to aid EMS implementation in the NCI.

Originality/value

This paper investigated the drivers of EMS with the opinions of construction professionals in the mainstream of the NCI through survey using to ensure wide coverage of respondents. Investigating the view of construction professionals in the micro, small, medium and large enterprises helped determine possible significant differences. Thus, practical implications of the study were also provided in a systematic manner.

Abstract

Purpose

There are several important strategic projects in the field of renewable energy in Egypt. Benban project is considered as one of the largest solar generation facilities in the world, which aims to increase clean energy produced, provide electricity needs for citizens and help to increase the volume of Egypt's electricity exports. The purpose of this paper is to explore the most important drivers and barriers that affect the implementation of green supply chain management (GSCM) practices in the field of solar energy production.

Design/methodology/approach

It is an exploratory research that conducts a case study about solar energy companies operating in Benban, south Egypt. It adopts a mixed approach; qualitative and quantitative research strategy to test the relationship between dependent and independent variables through a survey.

Findings

This research concluded that normative drivers involving stakeholder pressure are of the greatest drivers of GSCM practice, while external barriers including lack of government regulations and government support, poor supplier commitment, customers’ unawareness of sustainable green products, lack of markets receiving and manufacturing recycled materials, lack of renewal or technological innovation in markets and lack of human resources or expertise in market are among the biggest barriers to GSCM implementation.

Research limitations/implications

The researchers collected 30 responses during the field survey, which is a nonrandom sample that does not allow generalization. In addition, samples are only from companies in the solar energy sector only.

Originality/value

As there is a need for research that addresses sustainability practices and solutions in developing countries, especially in Egypt, this paper theoretically contributes to literature by proposing a conceptual framework that identifies the drivers and barriers of GSCM from the existing literature, then investigates and measures their impact on the implementation of GSCM on an Egyptian case study. As regards the practical contribution, this research is a trial to experimentally test the importance of top management’s role in motivating and training employees to improve the brand image of their company and making them aware of the benefits of the successful GSCM implementation.

Abstract

Purpose

International construction joint ventures (ICJVs) are an effective strategy for construction companies worldwide for delivering large and complex projects. Despite numerous ICJVs studies, there is a lack of comprehensive empirical examination of what drives ICJVs implementation. This study aims to investigate the key drivers for implementing ICJVs through an international survey.

Design/methodology/approach

Grounded on a comprehensive literature review and structured questionnaire survey, 123 ICJV experts' responses from 24 different countries/jurisdictions were analyzed using inferential and descriptive statistics. Mann–Whitney U test was used to determine any divergence of ranking of the drivers by the experts. Factor analysis (FA) was used to identify the clusters underlying the key drivers. Rank agreement analysis was later used to investigate the consensus between experts from developing and developed countries/jurisdictions on their ranking of the clusters.

Findings

Out of 34 factors, 26 factors greatly drive the implementation of ICJVs. Mann–Whitney U test results prove the absence of significant disparity among the experts in the ranking of the drivers. Six clusters were obtained through factor analysis (FA), namely, market-penetration and innovation-driven drivers, legal and market-driven drivers, fiscal incentives and market expansion drivers, personal branding drivers, sustainable advantage/power drivers and industrial and organizational promotion drivers. Rank agreement analysis exhibited varied levels of concurrence between professionals from developed and developing countries/jurisdictions.

Practical implications

The appreciation of the factors motivating ICJVs is beneficial to the successful implementation of ICJV strategies. A clear understanding of the drivers can help practitioners and policymakers to customize their ICJVs to reap the expected benefits.

Originality/value

The study has generated valuable insights into the factors that are greatly driving the implementation of ICJVs worldwide. While the findings of this study provide a profound contribution to theory and practice, it contributes to sustainable growth in different perspectives.

The purpose of this paper is to provide a systematic review of research studies on the drivers and consequences of corporate social responsibility (CSR).

Abstract

Purpose

The purpose of this paper is to provide a systematic review of research studies on the drivers and consequences of corporate social responsibility (CSR).

Design/methodology/approach

This paper used a systematic literature review using research papers published on the drivers and consequence of global CSR from 2010 to 2020.

Findings

The findings of this paper show that the principal themes of published research articles on the drivers and consequences of CSR are internal drivers, external drivers and consequences of CSR. Publications on the drivers and consequences of global CSR have been dominated by studies that used quantitative approach and cross-sectional design. A significant number of studies also used secondary data source with most of these studies not being sensitive to sectorial influences. More importantly, this study revealed that the emphasis of CSR on actions that demonstrate social responsibility is more associated with overall financial performance and firm value when contrasted against ethical statements of social responsibility which is associated with weaker firm financial performance and outcomes. Moreover the review indicated that the level of CSR engagement and disclosure has been associated with higher share prices whereas low level of CSR disclosure in sensitive industries results in lower share prices. In addition, employees’ intention has been identified as a critical driver for CSR activities. Furthermore, it was also identified that firms engage in CSR because of internal institutional factors such as ethical corporate culture and top management commitment, whereas external drivers of CSR include socio-political factors, globalisation and environmental accountability.

Practical implications

CSR is an area that can be harnessed to contribute to sustainable solutions to global challenges. It also provides an added advantage of ensuring that the perpetuation of the relationship between businesses and society are more complementary.

Originality/value

This review is one of the few studies focussed on highlighting the drivers and consequences of global CSR. This review also provides proof of the areas of research that need attention and provides recommendation on future areas of study on the drivers and consequences of global CSR.
