Abstract
Purpose
This study aims to review recent advances towards the implementation of ANN and NLP applications during the budgeting phase of the construction process. During this phase, construction companies must assess the scope of each task and map the client’s expectations to an internal database of tasks, resources and costs. Quantity surveyors carry out this assessment manually with little to no computer aid, within very austere time constraints, even though these results determine the company’s bid quality and are contractually binding.
Design/methodology/approach
This paper seeks to compile applications of machine learning (ML) and natural language processing in the architectural engineering and construction sector to find which methodologies can assist this assessment. The paper carries out a systematic literature review, following the preferred reporting items for systematic reviews and meta-analyses guidelines, to survey the main scientific contributions within the topic of text classification (TC) for budgeting in construction.
Findings
This work concludes that it is necessary to develop data sets that represent the variety of tasks in construction, achieve higher accuracy algorithms, widen the scope of their application and reduce the need for expert validation of the results. Although full automation is not within reach in the short term, TC algorithms can provide helpful support tools.
Originality/value
Given the increasing interest in ML for construction and recent developments, the findings disclosed in this paper contribute to the body of knowledge, provide a more automated perspective on budgeting in construction and break ground for further implementation of text-based ML in budgeting for construction.

Abstract
Purpose
To estimate the volatility of exchange and stock markets and examine its spillover within and across the member countries of BRICS during COVID-19 and the conflict between Russia and Ukraine.
Design/methodology/approach
The study utilizes the “dynamic conditional correlation-generalized autoregressive conditional heteroskedasticity (DCC-GARCH)” approach of Gabauer (2020). The volatility of the markets is calculated following the approach of Parkinson (1980). The sample dataset comprises the daily volatility of the stock and exchange markets for 35 months, from November 2019 to September 2022.
Findings
The study confirms the existence of contagion effects among member countries. Volatility spillover between exchange and stock markets is low within the country but substantial across borders. Russian contribution increased significantly during the conflict with Ukraine, and other countries also witnessed a surge in the spillover index during the pandemic and war.
Research limitations/implications
It adds to the body of literature by emphasizing the necessity of comprehending the economies' behavior and interdependence. Offers insightful information to decision-makers who must be more watchful regarding the financial crisis and its regional spillover.
Originality/value
The study is the first to explore the contagion of volatility among the BRICS countries during the two biggest crisis periods of the decade.

Abstract
Purpose
This case study sought to investigate the relationship between pre-service teachers’ participation in designing and delivering one-on-one literacy intervention lessons to beginning readers and their own evolving self-efficacy in literacy instruction.
Design/methodology/approach
The study was embedded within a 4000-level course in the elementary education major where pre-service teachers learn to administer, analyze and interpret a variety of literacy assessments. Based on the results of these assessments, pre-service teachers designed and implemented literacy lessons (twice a week, 30-min sessions) that addressed the beginning readers' specific instructional needs. Through collecting pre/post data with their first-grade intervention students, and participating in reflective “check-ins” (surveys, a focus group and end-of-course written reflection), a portrait of increased pre-service teacher self-efficacy in literacy instruction comes into focus.
Findings
The data showed, primarily through the thematic analysis of qualitative data, that the experience of conducting a one-on-one intervention with a striving reader impacted pre-service teachers’ self-efficacy positively.
Research limitations/implications
The methodology of this study was limited by the small sample size and the low participant response rate on the quantitative survey measure.
Practical implications
This paper highlights one aspect in which clinically-rich field experiences can make a difference in the literacy instruction self-efficacy of pre-service teachers.
Originality/value
This study adds to the support for authentic instructional applications of course content in educator preparation programs, specifically in Professional Development School (partner school system) contexts. The aspect of observing and measuring intervention student progress was one lens through which pre-service teachers viewed their efficacy. Further investigations focusing on other assessment-instruction cycles could provide additional insights.

Abstract
Purpose
The article extends the distinction of semantic from syntactic labour to comprehend all forms of mental labour. It answers a critique from de Fremery and Buckland, which required envisaging mental labour as a differentiated spectrum.
Design/methodology/approach
The paper adopts a discursive approach. It first reviews the significance and extensive diffusion of the distinction of semantic from syntactic labour. Second, it integrates semantic and syntactic labour along a vertical dimension within mental labour, indicating analogies in principle with, and differences in application from, the inherited distinction of intellectual from clerical labour. Third, it develops semantic labour to the very highest level, on a consistent principle of differentiation from syntactic labour. Finally, it reintegrates the understanding developed of semantic labour with syntactic labour, confirming that they can fully and informatively occupy mental labour.
Findings
The article further validates the distinction of semantic from syntactic labour. It enables to address Norbert Wiener's classic challenge of appropriately distributing activity between human and computer.
Research limitations/implications
The article transforms work in progress into knowledge for diffusion.
Practical implications
It has practical implications for determining what tasks to delegate to computational technology.
Social implications
The paper has social implications for the understanding of appropriate human and machine computational tasks and our own distinctive humanness.
Originality/value
The paper is highly original. Although based on preceding research, from the late 20th century, it is the first separately published full account of semantic and syntactic labour.

Abstract
Purpose
The primary objective of this paper is to investigate the relation between the joint provision of sustainability assurance and the readability of sustainability assurance statements. Additionally, it explores whether the presence of a female assurance partner influences the relation between the joint provision of sustainability assurance and the readability of sustainability assurance statements.
Design/methodology/approach
We analyzed a dataset comprising 882 firm-year observations from companies operating in sustainability sensitive industries for the period that spans the years 2016–2018.
Findings
The research indicates that joint sustainability assurance provision is associated with a more readable sustainability assurance statement, consistent with the “four-eyes” principle. Furthermore, the presence of a female assurance provider influences the joint assurance provision’s impact on sustainability assurance statement readability. Collectively, these results remain robust as they hold unchanged after controlling for endogeneity concerns.
Research limitations/implications
This study provides novel insights into the recent sustainability assurance literature, being the first to examine joint assurance provision, assurance partner gender and sustainability assurance statement readability.
Practical implications
This study has the potential to catalyze regulatory and policy initiatives by providing compelling evidence in favor of mandating joint audits within the area of sustainability assurance practices. Additionally, this research contributes to the ongoing discussion about gender diversity in accounting and nonaccounting assurance firms, providing evidence of the positive impact of female assurance partners on sustainability assurance statement readability.
Originality/value
The regression results provide preliminary evidence on how the presence of a female audit partner influences the relationship between the sustainability assurance joint provision and sustainability assurance statement readability, an issue that has not been examined before.

Abstract
Purpose
Generation Z will be the leading consumer group in the future. Using convenience stores, the study provides an in-depth analysis on Gen Z’s current experience and future expectations from retail stores. The study further highlights the differences between Gen Z’s perception of convenience stores across three different regions – the USA, South Korea and Japan.
Design/methodology/approach
This study conducted a series of in-depth, semi-structured interviews with 36 Gen Z participants from the USA (12), South Korea (11) and Japan (13). All interviews were first coded based on a preselected list of themes and were further coded with new themes that emerged from exploratory coding.
Findings
Each regional cohort varied in terms of how they experienced and what they expected from convenience stores. US participants showed negative or utilitarian attitudes toward convenience stores, whereas South Korean participants had a positive, personal attachment to them. In comparison, Japanese participants had a relatively neutral attitude. However, all three groups showed a common preference for smart technology and health concerns surrounding convenience store foods.
Practical implications
Convenience store chains should consider the cultural nuances when designing future services. The chains should further strive to remove the health concerns about the foods provided at the stores and design smart technologies that enhance user experience.
Originality/value
The present study broadens the knowledge in this budding consumer segment where current research is limited. It further sheds light on the variance among Gen Zers across different cultural contexts.

Abstract
Purpose
Upon the premises of social exchange theory (SET), this study aimed at hypothesizing and examining a serial mediation model that investigated the underlying mechanism through which a high-performance work system (HPWS) affects individuals’ future time perspective (FTP).
Design/methodology/approach
The hypothesized relationships were examined using responses collected from 275 employees from 15 local private banks and 40 established branches through a proportionate stratified sampling technique. The statistical package for social sciences (SPSS) PROCESS macro 3.0 and analysis of moment’s structure (AMOS) 24.0 were employed for data analysis purposes.
Findings
The study revealed that HPWS is indirectly related to the individuals’ FTP through workplace social courage (WSC) and employee well-being (EWB) sequentially. Prescriptions for theoretical and managerial implications were discussed, and future research viewpoints with limitations were acknowledged.
Originality/value
This study illuminated the underlying mechanism and theoretical logic linking HPWS and individuals’ FTP by proposing the serial mediating effect of WSC and EWB.

Abstract
Purpose
This study aims to investigate the implications for financial innovation and product development of differences between schools of jurisprudence (fiqh) pertaining across regional Muslim markets, and the consequences for global financial institutions.
Design/methodology/approach
The methodology is qualitative, drawing upon several sources. Firstly, differences in interpretation regarding the economic and moral responsibilities of financial institutions in Islamic and secular contexts. Secondly, contrasting tenets of schools of Islamic jurisprudence regarding the permissibility of products traded intra Muslim markets. Thirdly, characteristics of complex financial instruments traded in global secular markets prior to the credit crisis of 2007–2008.
Findings
Differences between Islamic and global secular interpretations regarding responsibilities of financial institutions militate against integrated markets across which products can be seamlessly traded. Global financial institutions should recognise that different Islamic schools of jurisprudence prioritise either legal form or substance of financial products, but not both simultaneously. This should be considered when designing new products for regional Muslim markets.
Practical implications
Global financial institutions which focus upon the legal (micro) form of new Islamic products should relate in investor prospectuses and marketing materials the extent to which these accommodate Islamic jurisprudence’s equal (macro) concern for public interest or maslahah. This may comprise the reallocation of risk from those unable to bear it to those willing to assume it for a price, reinforcing rather than compromising economic stability.
Originality/value
This study evaluates implications for product development and marketing for global financial institutions active in regional Muslim markets across which different Islamic schools of jurisprudence apply.
