Abstract

Purpose

This research aims to propose a model for the complex decision-making involved in the ecological restoration of mega-infrastructure (e.g. railway engineering). This model is based on multi-source heterogeneous data and will enable stakeholders to solve practical problems in decision-making processes and prevent delayed responses to the demand for ecological restoration.

Design/methodology/approach

Based on the principle of complexity degradation, this research collects and brings together multi-source heterogeneous data, including meteorological station data, remote sensing image data, railway engineering ecological risk text data and ecological restoration text data. Further, this research establishes an ecological restoration plan library to form input feature vectors. Random forest is used for classification decisions. The ecological restoration technologies and restoration plant species suitable for different regions are generated.

Findings

This research can effectively assist managers of mega-infrastructure projects in making ecological restoration decisions. The accuracy of the model reaches 0.83. Based on the natural environment and construction disturbances in different regions, this model can determine suitable types of trees, shrubs and herbs for planting, as well as the corresponding ecological restoration technologies needed.

Practical implications

Managers should pay attention to the multiple types of data generated in different stages of megaproject and identify the internal relationships between these multi-source heterogeneous data, which provides a decision-making basis for complex management decisions. The coupling between ecological restoration technologies and restoration plant species is also an important factor in improving the efficiency of ecological compensation.

Originality/value

Unlike previous studies, which have selected a typical section of a railway for specialized analysis, the complex decision-making model for ecological restoration proposed in this research has wider geographical applicability and can better meet the diverse ecological restoration needs of railway projects that span large regions.

Abstract

Purpose

This study aims to examine the role of fund family size on the money flow of Saudi Arabian open-end equity mutual funds. The author also investigates whether the relationship between fund flow and past return varies based on the fund's family size.

Design/methodology/approach

The study analyses 256 equity funds that operated in Saudi Arabia from 2006 until 2017. Pooled and fixed-effect regression models are used to test the relationship between mutual fund flow and family size.

Findings

The results indicate that fund flow is higher for large size family funds. The results also show that the relationship between mutual fund flow and past performance is more pronounced for large size families, which supports the concept that investors pay extra attention to funds' return and size.

Research limitations/implications

The author provides evidence of the significant effect of family size of mutual funds on future money flow, which helps fund managers to understand investors' motivations for allocating their cash.

Originality/value

This paper contributes to the literature by examining the impact of family size level on the interaction between fund flow and past performance. This study is believed to be the first to investigate the family size factor in Saudi Arabia using a comprehensive data set.

Abstract

Purpose

Academics and businesses alike have begun to recognise sustainability as a vital component of supply chain competitive advantage in recent years. Inconclusive results have been found in empirical studies of sustainable supply chain management (SSCM) that have ignored contextual variables concerning the dynamic role of firm capability in favour of testing alternative assumptions about the effect of various elements of the triple bottom line (TBL) on firm performance outcomes. The present study examines whether and how firm capabilities mediate the connection between SSCM, from a TBL standpoint, and firm financial performance outcomes.

Design/methodology/approach

Using the stakeholder theory, the study employed 325 survey responses from firms operating in different industries in Ghana (a less-researched context but one that plays a key role regarding SSCM practices) and the partial least squares structural equation model (PLS-SEM) technique to simultaneously assess the relationships amongst the variables.

Findings

It was discovered that the connections between all the TBL facets of SSCM practices and firm performance are positive and significant, and these relationships are mediated by firm capabilities.

Originality/value

By examining the underlying variables and relationships that contribute to the establishment of the rather complex relationship between SSCM practices from a TBL perspective and the performance of a firm, the research contributes to current knowledge on SSCM practices, firm capabilities and firm performance.

Abstract

Purpose

The study investigates the experiences of undergraduate students in using online learning platforms to study Accounting-related courses during the COVID-19 pandemic.

Design/methodology/approach

The study uses qualitative research approach and 89 undergraduate Accounting students from University of Professional Studies, Accra (UPSA) were purposively interviewed using semi-structured interview guide, observation and documentary evidence to achieve triangulation of data and results.

Findings

The study discovers that due to the Covid pandemic, the online Accounting learning system has a relative advantage over the physical classroom learning as the online pedagogy ensures that the students are safe and do not contract the virus. The findings further indicate that the university's engagement framework includes three units: engaging students with content on the university's Learning Management System (LMS), engaging students with their peers via group course WhatsApp platform and Zoom/Google Meet lectures, and engaging students with their instructors via the LMS, Zoom/Google Meet, and Group WhatsApp. Each unit is based on research-based best practices and strategies for online education such as the use of media (videos) to augment written course content and to improve student-to-content engagement, positive cognitive, collaborative, behavioural and emotional engagement of students. The university's strategies also encourage student-to-student involvement, as well as assessment and feedback. Regarding behavioural and emotional engagements, the study discovered that some lecturers' attitudes toward students coupled with insufficient administrative support influenced students to develop negative reactions to the use of online learning platforms for Accounting education.

Practical implications

This paper has the potential to inform and improve implementation of online Accounting education in developing countries where the digital divide is staggering and digital inclusion and infrastructure for online education are at a precarious stage that cannot be remedied overnight.

Social implications

The new context of Accounting education enables an increase in student enrolment because it does not require students to travel to or stay in a hostel for an extended period of time in order to earn an Accounting degree.

Originality/value

This study contributes to the Accounting education literature on emerging economies by providing new evidence of perception differences between higher education institutions and students. Education providers in emerging economies frequently adopt Western modes of online education without making structural adjustments. By empirically exploring students' opinions, this study challenges these managerial perceptions, and the findings will assist regulators and policymakers in making appropriate changes.

Abstract

Purpose

This paper proposes an intact framework for building life cycle energy estimation (LCEE), which includes three major energy sources: embodied, operational and mobile.

Design/methodology/approach

A systematic review is conducted to summarize the selected 109 studies published during 2012–2021 related to quantifying building energy consumption and its major estimation methodologies, tools and key influence parameters of three energy sources.

Findings

Results show that the method limitations and the variety of potential parameters lead to significant energy estimation errors. An in-depth qualitative discussion is conducted to identify research knowledge gaps and future directions.

Originality/value

With societies and economies developing rapidly across the world, a large amount of energy is consumed at an alarming rate. Unfortunately, its huge environmental impacts have forced many countries to take energy issues as urgent social problems to be solved. Even though the construction industry, as the one of most important carbon contributors, has been constantly and academically active, researchers still have not arrived at a clear consensus for system boundaries of life cycle energy. Besides, there is a significant difference between the actual and estimated values in countless current and advanced energy estimation approaches in the literature.

Abstract

Purpose

This study develops a conceptualization of NPD (new product development) complexity and explores how inter-organizational collaboration and conflict influence NPD performance.

Design/methodology/approach

An empirical examination tests the proposed relationships in the context of Korean manufacturing firms, which currently engage in NPD projects with their key partners. Structural equation modeling (SEM) was used to examine the hypotheses.

Findings

The findings suggest that a higher level of NPD complexity simultaneously calls for inter-organizational collaboration and conflict, and these two factors influence NPD performance in a conflicting manner: inter-organizational collaboration serves as a driver, and inter-organizational conflict acts as a barrier against NPD performance.

Originality/value

This study provides answers to the academic and practical calls by providing how NPD complexity should be managed in a way to increase NPD performance. This study provides insight into how manufacturing firms form inter-organizational collaboration practices and why they need to mitigate inter-organizational conflict.

Abstract

Purpose

The preferences and adoption of recycled materials by consumers are subject to a variety of factors, such as enablers and barriers. Despite this, there exists a paucity of research concerning stakeholders' perceived value and real purchase decision towards recycled products. Consequently, this research study aims to fill this gap by investigating stakeholders' perceived value of recycled products derived from construction and demolition (C&D) waste and its effect on purchase decisions.

Design/methodology/approach

Research data were collected from 219 valid questionnaires completed by Chinese stakeholders. Structural equation modeling (SEM) was then employed to test eight hypotheses.

Findings

The results show intrinsic cue (materials) and extrinsic cue (brand) influence the stakeholders’ judgment on C&D waste recycled products’ value and then their purchase intention. However, cues such as quality, word-of-mouth, price, policy and advertised have not play a significant role in practice.

Originality/value

This research study verified the significance of brand and material cues on decision making for purchasing C&D waste recycled products, providing new insights to policy making to enhance the uptake of C&D waste recycled products in construction industry.

Abstract

Purpose

This study aims to (1) validate the efficacy of contractual and relational governance in enhancing operational performance and (2) explore the influence of product complexity on the effectiveness of these governance mechanisms, thereby determining the optimal approach for varying levels of product complexity.

Design/methodology/approach

By utilizing a comprehensive theoretical framework encompassing transaction cost economics, social exchange theory and contingency theory, this research explores the intricate interplay between governance mechanisms, product complexity and operational performance, drawing insights from a dataset comprising 246 responses within Mainland China’s manufacturing sector. To rigorously test the proposed hypotheses, this study employed a hierarchical regression analysis.

Findings

The findings of this study are summarized as follows: (1) while both contractual governance and relational governance have a significant impact on operational performance, relational governance is found to be more effective than contractual governance in enhancing operational performance; and (2) the moderation effect of product complexity is evident, as it weakens the impact of contractual governance while simultaneously enhancing the positive influence of relational governance on operational performance.

Originality/value

The study uncovers a moderation effect of product complexity on the relationship between governance mechanisms and operational performance. This finding adds an original contribution to the literature by highlighting how product complexity can interact with governance strategies, providing practical insights for industries dealing with varying levels of product complexity.

Abstract

Purpose

Critical infrastructures (CIs) are essential components of the built environment. They ensure the interconnectivity and good operability of any major urban environment. CIs are exposed to several disruptions such as natural events, hazards or threats that may disturb their normal functionality. These disruptions may impact societies not only from a socio-economic perspective but also environmentally. Therefore, ensuring the resilience of CIs is crucial to modern cities. This paper aims to explore the main standards and criteria used to assess the resilience of CIs.

Design/methodology/approach

A three-stage systematic review process was adopted to retrieve relevant papers. A total of 44 papers were carefully selected, and the content analysis technique was used to thoroughly analyse the papers.

Findings

Results show that researchers’ interest to investigate the assessment criteria of CIs resilience increased after 2004. Further, a total of 28 resilience criteria of CIs were identified, of which the most reported ones are organisational resilience; performance loss, disruption and recovery process; resilience metrics and index; safety, security and risk analysis; societies/communities’ resilience and/or social-equity responsibility; dynamic networks connectivity; resilience through design and structural integrity; and economic resilience.

Originality/value

The findings of this research will serve as a solid foundation for the development of hypothesis for future empirical studies into the development of assessment criteria index for CI resilience. Further, the outcomes will contribute to the ongoing international discussions and debate on the appropriate ways to develop CI resilience.

Abstract

Purpose

The purpose of this study is to describe university students’ motivations for using Facebook as an informal learning tool and explore the key barriers that may inhibit learning on the social media platform.

Design/methodology/approach

A case study approach was adopted in this study. Participants were 82 university students who participated in “e-Tutor” – an informal learning activity, conducted through Facebook. Focus group interviews were conducted, and students’ interactions on Facebook were also analysed to understand their motives for using the social media platform for learning. The uses and gratifications theory was used to explore student motivations for participating in the learning activity.

Findings

Results suggest that students perceived Facebook as a potential tool for learning and identified multiple motivating factors for their participation that included information seeking, convenience, connectedness, entertainment and reward seeking. Results also show that time constraints, social anxiety and cultural issues may inhibit learners’ active participation on social media platforms such as Facebook.

Originality/value

This study outlines an approach to use readily available and low-cost technological tools in learning design and provides some insights for teachers to design ubiquitous and personalised learning environments for students using such technologies, particularly social media. Specifically, Facebook offered a way to engage students in informal learning which can supplement students’ formal learning trajectories at university. While the uses and gratifications students sought through Facebook had an overall positive effect on their participation in e-Tutor activity, certain barriers can impede student active participation in learning environments on social media sites such as Facebook.
