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

In this paper, the authors examine the association between conditional conservatism and deviations of the first digits of financial statement items from what are expected by Benford's Law.

Design/methodology/approach

This research uses data of companies listed on the London Stock Exchange. The authors measure deviations of first digits from Benford's Law following Amiram et al. (2015) and firm-year conditional conservatism following previous studies (Basu, 1997; Khan and Watts, 2009; García Lara et al., 2016). The authors use multiple regressions to provide evidence for their hypothesis.

Findings

The results show that conditional conservatism is positively associated with deviations from Benford's Law. The findings are robust across different measures of deviations and conditional conservatism. Also, the authors find that the relationship between deviations from Benford's Law and conditional conservatism is more pronounced for firms with debt issuance, and for leveraged firms facing financial distress. Next, the authors’ analyses confirm previous evidence by showing that the first digits of financial statement items of UK listed companies conform to Benford's Law at the firm-specific level and the market level, and deviations of income statements are larger than those of balance sheets and cash flow statements.

Research limitations/implications

The research makes significant contributions to the literature. First, this is the first study that provides empirical evidence suggesting that conditional conservatism may be a source of deviations from Benford’s Law. Second, the authors provide evidence confirming previous US findings (e.g. Amiram et al., 2015) showing that the distributions of first digits of financial statement items of UK listed companies also conform to Benford's Law.

Practical implications

The authors’ findings have implications for auditors. Auditors should be aware of “false positive” for material misstatements when using Benford's Law as a risk assessment procedure. While both conditional conservatism and earnings management are related to deviations from Benford's Law, conservatism-related biases could indicate less audit risks.

Originality/value

The authors provide new and original evidence suggesting that conditional conservatism is related to deviations from Benford's Law.

Abstract

Purpose

Impulse purchases are a phenomenon of interest in recent years that provides a high revenue stream for companies compared to planned purchases. Airports are a unique shopping environment. Travellers usually need to arrive at the airport early and can only utilise limited time to shop at duty-free stores, which makes the shopping experience time-constrained and has the potential to make impulse purchases. The main purpose of this research is to create a model to examine whether “time pressure” and “hedonic shopping motivation” lead to impulse shopping through the formation of “positive emotion” in the context of airport duty-free shops.

Design/methodology/approach

A questionnaire-based survey was conducted in this study. The data collection for this study targeted individuals who had previously used airline services for international travel and visited duty-free shops at international airports. A total of 502 valid subjects participated in this survey.

Findings

The findings indicated that time pressure and consumers’ hedonic motivations have a positive impact on emotions. Positive emotions have a positive impact on the occurrence of impulse purchases. Music and light can moderate the impact of hedonic motivation on emotion but cannot reduce the influence of time pressure on emotion. Social factor significantly moderates the positive association between hedonic shopping motivation and emotion.

Originality/value

The research collected data from various international airports and social media, enabling the findings to be generalised.

Abstract

Purpose

Poor mental health is a well-recognized issue in the construction sector. However, there is still little understanding of factors affecting construction employees’ awareness of mental health problems (MHP). This study aims to investigate the awareness of MHP among construction employees using the Health Belief Model (HBM). The research explores how various factors, such as perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action and self-efficacy, shape MHP awareness within the construction sector.

Design/methodology/approach

A structured four-step research methodology was employed. First, a literature review and expert validation identified 28 variables relevant to MHP awareness. A questionnaire was then developed and distributed to construction employees in Vietnam, with 238 valid responses collected. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed to validate the evaluation model. After that, fuzzy synthetic evaluation (FSE) was used to assess the importance of each dimension of MHP awareness.

Findings

The results indicate that perceived barriers and perceived benefits were the two most significant factors in MHP awareness. The remaining dimensions – perceived susceptibility, perceived severity, cues to action and self-efficacy – were found to have a lesser but notable impact on MHP awareness.

Originality/value

This research comprehensively analyzes MHP awareness among construction employees using the HBM framework. The findings suggested that Vietnamese firms should focus on increasing cues to action and self-efficacy to improve MHP awareness among construction employees. This study also proposed that construction firms should provide more stress-reduction activities and training programs suitable to the Vietnamese context for their employees.
