Abstract
Purpose
Establishing a more sustainable built environment is an increasing global concern for the construction industry. Despite the intrinsic and extrinsic obstacles the stakeholders face, huge efforts are required to transition to a smooth, sustainable construction (SC) practice. This study identifies and discusses cogent obstacles to SC in developing nations.
Design/methodology/approach
The Preferred Reporting Item for systematic reviews and Meta-Analysis (PRISMA) approach was employed to establish research work in SC for developing countries. The databases used were Scopus and Web of Science. Meta-analysis of keywords was analysed thematically. The initial broad search returned 8,420 publications which were filtered and reviewed in-depth to fit the aim of the study, produced only 21 relevant publications from the years 2000–2021.
Findings
The four identified themes of obstacles to SC in developing countries are as follows: construction professional training and education, clients' attitudes and awareness, construction industries' culture and capacity and governments' regulation, policies and economy. The key barriers identified from the meta-analysis include inadequate training and education amongst construction professionals, poor execution of sustainability ethics, poor populace attitude towards sustainability, poor awareness and understanding, dearth of precise data and integrated study and inappropriate priorities about sustainability.
Originality/value
The originality in this study are themes drawn from millennium development goals (MDGs) and sustainable development goals (SDGs) publications related to SC. Consequently, the final framework presented a holistic approach to surmounting the established limitations and aided recommendations for future studies. Thus, setting a background for developing strategies to overcome the limitations and further attain sustainable development (SD).

Abstract
Purpose
Magnetic hysteresis holds significant technical and physical importance in the design of electromagnetic components. Despite extensive research in this area, modeling magnetic hysteresis remains a challenging task that is yet to be fully resolved. The purpose of this paper is to study vector hysteresis play models for anisotropic ferromagnetic materials in a physical, thermodynamical approach.
Design/methodology/approach
In this work, hysteresis play models are implemented to interpret magnetic properties, drawing upon classical rate-independent plasticity principles derived from continuum mechanics theory. By conducting qualitative and quantitative verification and validation, various aspects of ferromagnetic vector hysteresis were thoroughly examined. By directly incorporating the hysteresis play models into the primal formulations using fixed point method, the proposed model is validated with measurements in a finite element (FE) environments.
Findings
The proposed vector hysteresis play model is verified with fundamental properties of hysteresis effects. Numerical analysis is performed in an FE environment. Measured data from a rotational single sheet tester (RSST) are validated to the simulated results.
Originality/value
The results of this work demonstrates that the essential properties of the hysteresis effects by electrical steel sheets can be represented by the proposed vector hysteresis play models. By incorporation of hysteresis play models into the weak formulations of the magnetostatic problem in the h-based magnetic scalar potential form, magnetic properties of electrical steel sheets can be locally analyzed and represented.

Abstract
Purpose
The main purpose of this paper is to explore whether the nature of innovation is accumulative or radical and to what extent past year accumulation of technology stock can predict future innovation. More importantly, the authors are concerned with whether a change of policy regime or a variance in the quality of technology will moderate the nature of innovation.
Design/methodology/approach
The authors examined a dataset of 3.6 million Chinese patents during 1985–2015 and constructed more than 5 million citation pairs across 8 sections and 128 classes to track knowledge spillover across technology fields. The authors used this citation dataset to calculate the technology innovation network. The authors constructed a measure of upstream invention, interacting the pre-existing technology innovation network with historical patent growth in each technology field, and estimated measure's impact on future innovation since 2005. The authors also constructed three sets of metrics – technology dependence, centrality and scientific value – to identify innovation quality and a policy dummy to consider the impact of policy on innovation.
Findings
Innovation growth is built upon past year accumulation and technology spillover. Innovation grows faster for technologies that are more central and grows more slowly for more valuable technologies. A pro-innovation and pro-intellectual property right (IPR) policy plays a positive and significant role in driving technical progress. The authors also found that for technologies that have faster access to new information or larger power to control knowledge flow, the upstream and downstream innovation linkage is stronger. However, this linkage is weaker for technologies that are more novel or general. On most occasions, the nature of innovation was less responsive to policy shock.
Originality/value
This paper contributes to the debate on the nature of innovation by determining whether upstream innovation has strong predictive power on future innovation. The authors develop the assumption used in the technology spillover literature by considering a time-variant, directional and asymmetric matrix to model technology diffusion. For the first time, the authors answer how the nature of innovation will vary depending on the technology network configurations and policy environment. In addition to contributing to the academic debate, the authors' study has important implications for economic growth and industrial or innovation management policies.

Abstract
Purpose
This paper describes an exploratory, international research collaboration that seeks to gain a deeper understanding of the development and experiences of peer leaders in higher education across different international contexts, namely the USA, Canada (CAN), Australasia (Australia and New Zealand) (ANZ), the United Kingdom (UK) and South Africa (SA).
Design/methodology/approach
Data are summarized and compared across each of the participating countries, providing a more global context and depth of perspective on peer leadership (PL) in higher education than is currently available in the literature.
Findings
The findings highlight some apparent differences between countries in relation to student engagement in peer leader roles and the ways in which PL is supported by higher education institutions, as well as some similarities across the different international contexts, particularly in the way peer leaders view the benefits of their involvement in PL.
Originality/value
These insights provide a valuable addition to the literature on PL and practical information to higher education institutions for supporting student leadership development and involvement.

Abstract
Purpose
The purpose of this case study was to complement existing weeding and retention criteria beyond the most used methods in academic libraries and to consider citation counts in the identification of important scholarly works.
Design/methodology/approach
Using a small sample of items chosen for withdrawal from a small liberal arts college library, this case study looks at the use of Google Scholar citation counts as a metric for identification of notable monographs in the social sciences and mathematics.
Findings
Google Scholar citation counts are a quick indicator of classic, foundational or discursive monographs in a particular field and should be given more consideration in weeding and retention analysis decisions that impact scholarly collections. Higher citation counts can be an indicator of higher circulation counts.
Originality/value
The authors found little indication in the literature that Google Scholar citation counts are being used as a metric for identification of notable works or for retention of monographs in academic libraries.

Abstract
Purpose
Disinformation on social media is a serious issue. This study examines the effects of disinformation on COVID-19 vaccination decision-making to understand how social media users make healthcare decisions when disinformation is presented in their social media feeds. It examines trust in post owners as a moderator on the relationship between information types (i.e. disinformation and factual information) and vaccination decision-making.
Design/methodology/approach
This study conducts a scenario-based web survey experiment to collect extensive survey data from social media users.
Findings
This study reveals that information types differently affect social media users' COVID-19 vaccination decision-making and finds a moderating effect of trust in post owners on the relationship between information types and vaccination decision-making. For those who have a high degree of trust in post owners, the effect of information types on vaccination decision-making becomes large. In contrast, information types do not affect the decision-making of those who have a very low degree of trust in post owners. Besides, identification and compliance are found to affect trust in post owners.
Originality/value
This study contributes to the literature on online disinformation and individual healthcare decision-making by demonstrating the effect of disinformation on vaccination decision-making and providing empirical evidence on how trust in post owners impacts the effects of information types on vaccination decision-making. This study focuses on trust in post owners, unlike prior studies that focus on trust in information or social media platforms.

Abstract
Purpose
This study aims to investigate the effect of servant leadership on employee organizational identification and career satisfaction through the mediating lens of leader-member-exchange (LMX). Furthermore, this study also examines whether perceived organizational support (POS) strengthens the positive effect of servant leadership on LMX and subsequently, on employee organizational identification and career satisfaction.
Design/methodology/approach
Survey data were collected from 314 respondents working in hotels in United States of America (USA). Structural equation modeling (SEM), hierarchical moderation analysis and bootstrapping were used to test the study hypotheses.
Findings
Servant leadership was found to positively influence employee organizational identification and career satisfaction. Further, analysis revealed that LMX partially mediated the positive relationship between servant leadership and employee career satisfaction and fully mediated the positive relationship between servant leadership and organizational identification. However, although POS moderated the indirect relationship between servant leadership and employee’ career satisfaction, it did not moderate the indirect relationships between servant leadership and organizational identification.
Practical implications
This study provides insight into the nexus of servant leadership and organizational support in hospitality industry to foster the employee organizational identification and career satisfaction which are extremely needed for competitive advantage in hotel industry.
Originality/value
This study addresses recent calls for future researchers to investigate the important of servant leadership in the hospitality industry.

Abstract
Purpose
There has been limited research on why football clubs contribute to charity. This paper examines how football clubs and their charitable conduits report information when discussing their connectedness. In addition, it explores reasons why, and the extent to which, football clubs support altruism via such charitable vehicles.
Design/methodology/approach
Case studies of four major football teams (Manchester City/Manchester United in England and AC Milan/Inter Milan in Italy) are discussed, with formal reports of the clubs and their associated charitable conduits being analysed.
Findings
Boundaries between the clubs and their charitable conduits are frequently blurred. Evidence suggests that acknowledging the co-existence of different factors may help to understand what is reported by these organisations and address some of the caveats in terms of autonomy and probity of their activities and reporting practices.
Research limitations/implications
The research uses case studies of four major ‘powerhouses’ of the game and their associated charitable spinoffs. While this is innovative and novel, expanding the research to investigate more clubs and their charitable endeavours would allow greater generalisations.
Practical implications
The study provides material that can be used to reflect on the very topical subject of ‘sportswashing’. This has the potential to input to deliberations relating to the future governance of the game.
Originality/value
The paper explores relationships between businesses and charities/nonprofits in a sector so far little investigated from a charitable accountability perspective. It suggests that motives for engaging in charitable activity and highlighting such engagement may extend beyond normal altruism or warm-glow emotions.
