Abstract

Purpose

Due to the complexity and diversity of megaprojects, the architectural programming process often involves multiple stakeholders, making decision-making difficult and susceptible to subjective factors. This study aims to propose an architectural programming methodology system (APMS) for megaprojects based on group decision-making model to enhance the accuracy and transparency of decision-making, and to facilitate participation and integration among stakeholders. This method allows multiple interest groups to participate in decision-making, gathers various perspectives and opinions, thereby improving the quality and efficiency of architectural programming and promoting the smooth implementation of projects.

Design/methodology/approach

This study first clarifies the decision-making subjects, decision objects, and decision methods of APMS based on group decision-making theory and value-based architectural programming methods. Furthermore, the entropy weight method and fuzzy TOPSIS method are employed as calculation methods to comprehensively evaluate decision alternatives and derive optimal decision conclusions. The workflow of APMS consists of four stages: preparation, information, decision, and evaluation, ensuring the scientific and systematic of the decision-making process.

Findings

This study conducted field research and empirical analysis on a practical megaproject of a comprehensive transport hub to verify the effectiveness of APMS. The results show that, in terms of both short-distance and long-distance transportation modes, the decision-making results of APMS are largely consistent with the preliminary programming outcomes of the project. However, regarding transfer modes, the APMS decision-making results revealed certain discrepancies between the project's current status and the preliminary programming.

Originality/value

APMS addresses the shortcomings in decision accuracy and stakeholder participation and integration in the current field of architectural programming. It not only enhances stakeholder participation and interaction but also considers various opinions and interests comprehensively. Additionally, APMS has significant potential in optimizing project performance, accelerating project processes, and reducing resource waste.

Abstract

Purpose

Construction activities are anticipated to experience steady growth worldwide, resulting in massive construction and demolition waste (CDW). Despite introducing five designing out waste (DoW) principles to combat CDW from the early design stage, the design process remains a notable contributor to CDW generation due to designers’ limited knowledge and experience. The decision-making process in identifying and selecting DoW solutions is relatively underexplored in the current literature. This study aims to bridge this gap by reviewing existing literature to investigate the implementation of DoW principles and uncover potential areas to support designers in selecting DoW solutions for their projects.

Design/methodology/approach

Following the Preferred Reporting Item for systematic reviews and Meta-Analysis (PRISMA) protocol, a systematic literature review is adopted to analyse 50 selected articles published from 2000 to 2023 in order to develop the conceptual framework, which was subsequently reviewed by industry experts.

Findings

This review critically examines the current state of DoW implementation, the decision-making criteria for selecting DoW solutions and the available tools for DoW implementation. Existing limitations and future research directions to aid DoW in decision-making were identified. Drawing from the review’s findings, a conceptual framework is formulated to develop a decision support tool for selecting DoW alternatives.

Originality/value

The outcome of this review offers researchers insight into identifying existing gaps and potential areas to aid the DoW decision-making process. Construction professionals can use the findings to develop a decision support tool for selecting DoW alternatives, thereby minimising waste generation in construction projects.

Abstract

Purpose

Construction and demolition waste has emerged as a significant challenge for sustainable development globally. Hence, construction waste management (CWM) is considered one of the critical sustainable deliveries stipulated in various green building rating systems (GBRSs), including Homestar in New Zealand (NZ). The 6 Homestar rating is mandated for use by the national public housing provider. However, no empirical study has been conducted on CWM in 6 Homestar dwellings. This study investigates the current practice of CWM in those projects.

Design/methodology/approach

Primary data were extracted from 6 Homestar built assessment submissions for 100 public housing projects. The waste reports provided quantitative data to calculate the waste generation rate (WGR), waste diversion rate (WDR) and diverted waste rate (DWR) for descriptive analysis. These findings underwent further exploration by analysing site waste management plans.

Findings

With the aid of on- and off-site sorting and the recycling centre, a significant WDR is achieved at an average of 75.6%. However, diverted waste is treated at a low-priority level in the waste management hierarchy, and WGR remains relatively high.

Originality/value

The findings of this study can serve as valuable resources for managers in formulating comprehensive waste management plans and for policymakers in developing strategies and policies towards enhancing CWM practices. The study suggested the need for further focus towards minimising construction waste (CW) from the early design plan to achieve the construction industry's zero-waste target.

Abstract

Purpose

This study aims to investigate the impact of supply chain concentration (SCC) on corporate research and development (R&D) investment and determine the moderating roles of industry concentration and financing constraints on the relationship between SCC and R&D investment.

Design/methodology/approach

The study collected data from Chinese listed companies, used the fixed effects model to test the research hypotheses and further used the two-stage Heckman test and propensity score matching (PSM) to address potential endogeneity issues.

Findings

The result reveals a negative impact of SCC on corporate R&D investment. In addition, industry concentration mitigates the negative impact of SCC on corporate R&D investment, but financing constraints strengthen the negative impact.

Originality/value

This study introduces the concept of SCC and empirically tests its effect on R&D investment, further explaining the lack of corporate innovation. This study inspires companies to strengthen SC management and weigh the level of SCC with environmental factors.

Abstract

Purpose

The main purpose of this study is to determine the factors affecting the adoption of telemedicine services as mobile health apps in the Jordanian context by extending the technology acceptance model (TAM).

Design/methodology/approach

A quantitative research approach with an online survey was used to collect data from 306 Jordanian respondents to achieve the main purpose. The partial least squares structural equation modeling (PLS-SEM) approach was used to analyze collected data.

Findings

The results mainly confirmed that the intention to use mobile health apps (otherwise known as AMAN apps in Jordan) is significantly influenced by social influence, perceived usefulness and perceived ease of use, trust in government and social media awareness. Next, contrary to what is expected, culture does not moderate the association between perceived ease of use and behavioral intention to use the AMAN app, and hence the related hypothesis was not supported. To conclude, the results show that the actual use of the AMAN app is significantly influenced by behavioral intention, and hence, the final hypothesis was supported.

Originality/value

The current research contributed to the literature on information technology (IT)/information systems (IS) acceptance and use by switching the investigation efforts from the acceptance of IT/IS to the adoption of protection technology in the crisis era.

Abstract

Purpose

Informal female entrepreneurship (IFE) represents a significant yet understudied dimension of economic activity globally. This research aims to conduct a systematic literature review (SLR) on IFE.

Design/methodology/approach

This SLR delves into the intricate landscape of IFE, examining scholarly contributions sourced from the Web of Science Social Sciences Citation Index database.

Findings

By synthesizing existing literature, this review sheds light on the multifaceted dynamics surrounding IFE, encompassing factors such as socioeconomic contexts, cultural influences and institutional frameworks. Moreover, this study underscores the importance of addressing the unique challenges and opportunities faced by women engaged in informal entrepreneurial activities. In doing so, it not only enriches our understanding of female entrepreneurship but also underscores the need for tailored policies and interventions to support women in these endeavours.

Originality/value

This inquiry’s relevance stems from the pivotal role that women play in informal economies, which often remain obscured by traditional economic metrics. This review contributes to the scholarly discourse by proposing a research agenda to advance knowledge and inform future investigations into this critical domain.

Abstract

Purpose

Digital health or digital healthcare, is a broad, multidisciplinary concept that includes concepts from an intersection between technology and healthcare. Digital health applies digital transformation to the healthcare field, incorporating software, hardware and services. The usefulness of digital health technologies such as digital contact tracing apps (CTAs) depends deeply on the acceptance to use them. Accordingly, the main purpose of this study is to explore the usage of CTAs by integrating the protection motivation theory (PMT) and technology acceptance model (TAM) in the Jordanian context.

Design/methodology/approach

Partial least squares structural equation modelling was employed to test empirically the integrated research model against data collected from 420 respondents, leading to the identification of the important determinants for the usage of CTAs.

Findings

The results reveal that perceived severity and perceived vulnerability have a significant positive impact on the perceived need for CTAs, which, in turn, affects the individuals’ intention to use CTAs. It also reveals that perceived trust in government, perceived privacy and perceived usefulness have a significant positive impact on individuals’ intention to use CTAs, which, in turn, affects the usage of CTAs. In contrast, perceived ease of use did not find any significant relationship, and hence hypothesis H7 was not supported. Lastly, social media awareness has a significant positive impact on perceived usefulness and ease of use.

Originality/value

This study is considered among the first studies in the Jordanian context that integrate the PMT and TAM to gain a better understanding of the critical determinants for the acceptance and usage of CTAs in the context of pandemics.

Abstract

Purpose

This paper aims to explore examine the therapeutic potential of head-mounted display (HMD)-based Virtual Reality Relaxation Therapy (VRRT) sessions for people individuals with dementia in Jordan.

Design/methodology/approach

This cross-sectional survey recruited 75 dementia-diagnosed elderly individuals from three Jordanian care homes. A VRRT intervention comprising 10 tailored RT sessions held over the course of five weeks was administered to the participants. Apathy, cognitive performance, anxiety and depression were evaluated before and after the intervention to determine any changes. The Person-Environment Apathy Rating Scale's (PEARS) Arabic translation's validity and reliability were also evaluated.

Findings

The VRRT intervention yielded noteworthy results in reducing apathy, as indicated by a substantial decrease in PEARS scores from 17.20 to 11.15. The findings of the study revealed that the participants demonstrated enhanced cognitive abilities, as evidenced by a significant rise in their Saint Louis University Mental Status ratings, which increased from 15.11 to 19.70. The levels of anxiety and depression exhibited a significant decrease subsequent to the implementation of VRRT, with anxiety levels decreasing from 13.66 to 8.23 and depression levels decreasing from 13.62 to 9.33. Furthermore, a notable 70% of participants demonstrated statistically significant decreases in indifference.

Practical implications

This study makes a significant contribution to the advancement of innovative treatment approaches aimed at addressing the needs of the aging population, hence enhancing health outcomes and raising the quality of care in Jordan.

Originality/value

The effectiveness of VRRT in reducing apathy among Jordanian senior citizens residing in nursing homes has not yet been fully investigated. Therefore, this paper seeks to assess the effectiveness of HMD-based VRRT by conducting pre- and post-intervention evaluations. This research aims to provide valuable insights into the applicability and significance of VRRT in the Jordanian context, contributing to the development of culturally appropriate and cutting-edge therapeutic interventions for older individuals in Jordan. Through this study, the authors aim to promote improved health and elevated standards of care for this population.

Abstract

Purpose

The purpose of this study is to use a lifetime income measure to evaluate the long-run housing affordability for an understudied cohort of households in the literature – the millennials. The authors do this in the context of Malaysia, measuring long-run affordability for four housing types across geographic locations and income distributions.

Design/methodology/approach

This study calculates a long-run housing affordability index (HAI) using data on house prices and household incomes. Essentially a ratio of predicted lifetime incomes to house prices, the HAI is computed for four common housing types in Malaysia from 2005 to 2016 and for six states in the country. The HAI is also compared across four income percentiles.

Findings

The analysis reveals varying patterns of housing affordability among different states in Malaysia. Housing affordability has declined since 2010, with most housing types being unaffordable for millennial-led households with the lowest income. Housing is most affordable for those in the highest income bracket, although even here, there are pockets of unaffordable housing as well.

Practical implications

Based on the findings, this study proposes three targeted interventions to improve housing affordability for Malaysian millennials.

Originality/value

This study fills a gap in the literature by examining the long-run housing affordability of Malaysian millennial-led households based on both geographic location and income distribution. The millennial population is understudied in the housing affordability literature, making this study a valuable contribution to the field.
