Abstract
Purpose
The purpose of this paper is to propose a system dynamic simulated process model for maintenance work management incorporating the Fourth Industrial Revolution (4IR) technologies.
Design/methodology/approach
The extant literature in physical assets maintenance depicts that poor maintenance management is predominantly because of a lack of a clearly defined maintenance work management process model, resulting in poor management of maintenance work. This paper solves this complex phenomenon using a combination of conceptual process modeling and system dynamics simulation incorporating 4IR technologies. A process for maintenance work management and its control actions on scheduled maintenance tasks versus unscheduled maintenance tasks is modeled, replicating real-world scenarios with a digital lens (4IR technologies) for predictive maintenance strategy.
Findings
A process for maintenance work management is thus modeled and simulated as a dynamic system. Post-model validation, this study reveals that the real-world maintenance work management process can be replicated using system dynamics modeling. The impact analysis of 4IR technologies on maintenance work management systems reveals that the implementation of 4IR technologies intensifies asset performance with an overall gain of 27.46%, yielding the best maintenance index. This study further reveals that the benefits of 4IR technologies positively impact equipment defect predictability before failure, thereby yielding a predictive maintenance strategy.
Research limitations/implications
The study focused on maintenance work management system without the consideration of other subsystems such as cost of maintenance, production dynamics, and supply chain management.
Practical implications
The maintenance real-world quantitative data is retrieved from two maintenance departments from company A, for a period of 24 months, representing years 2017 and 2018. The maintenance quantitative data retrieved represent six various types of equipment used at underground Mines. The maintenance management qualitative data (Organizational documents) in maintenance management are retrieved from company A and company B. Company A is a global mining industry, and company B is a global manufacturing industry. The reliability of the data used in the model validation have practical implications on how maintenance work management system behaves with the benefit of 4IR technologies' implementation.
Social implications
This research study yields an overall benefit in asset management, thereby intensifying asset performance. The expected learnings are intended to benefit future research in the physical asset management field of study and most important to the industry practitioners in physical asset management.
Originality/value
This paper provides for a model in which maintenance work and its dynamics is systematically managed. Uncontrollable corrective maintenance work increases the complexity of the overall maintenance work management. The use of a system dynamic model and simulation incorporating 4IR technologies adds value on the maintenance work management effectiveness.

Abstract
Purpose
The link between supply chain agility (SCA) and performance has been tested in previous research with different samples and results. The present paper quantitatively analyses and summarises the impact of SCA on performance found in previous empirical papers and determines the influence of several identified moderators.
Design/methodology/approach
Using a meta-analysis approach based on a systematic literature review, a total of 63 empirical papers comprising a sample of 14,469 firms were meta-analysed to consider substantive (type of performance and SCA operationalisation) and extrinsic (economic region and industry) moderators.
Findings
Results confirm a significantly large, positive correlation between SCA and performance. None of the analysed moderators has enabled the identification of any significant differences between the SCA and performance correlations by subgroup. However, high heterogeneity in total variance, both in the full sample and the subgroups by moderator, demands further rigorously reported empirical research on this topic with clearly conceptualised variables and frameworks and the use of validated scales.
Research limitations/implications
Several research gaps and best practice recommendations have been indicated to improve future empirical research on this topic.
Practical implications
Practitioners in different economic regions and industries will find consistent evidence of improvements in performance through SCA.
Originality/value
No meta-analysis has been found in previous research to estimate the value of the correlation between SCA and performance and the influence of moderating variables.

Abstract
Purpose
This study aims to analyze the lean supply chain management (LSCM) strategy's role as a mechanism to address technology uncertainty and provide organizations with competitive advantage.
Design/methodology/approach
An empirical study was conducted of 276 Spanish focal firms in industrial sectors that occupy an intermediate position in the supply chain to investigate the influence of technology uncertainty on LSCM implementation and the latter's effect on operational performance and competitiveness. A covariance-based structural equation model (CB-SEM) was used to test three hypotheses.
Findings
Technological uncertainty encourages progress in the implementation of lean throughout the supply chain and so is a mechanism that not only brings stability to the focal company but also improves its performance and puts it in a better competitive position.
Practical implications
Managers are suggested to consider the strategic integration with supply chain partners and the establishment of long-term relationships based on trust and commitment advocated by LSCM to enhance organizations' capabilities and effectively and flexibly respond to technological changes.
Originality/value
This study focuses on the effects of environmental uncertainty on the supply chain. The past literature has focused on the behavior of individual firms to deal with uncertainty, but this work shifts the level of analysis to the supply chain. Therefore, the strategic change to deal with what is happening in the environment is now switched to the supply chain level.

Abstract
Purpose
This paper analyses the way that the industry's competitive environment and the company's strategy influence the implementation of the supply chain's (SC’s) triple-A capabilities (agility, adaptability and alignment). Two competitive environment variables are analysed: competitive intensity of the industry and complexity of the SC. Two opposing competitive strategies are also considered: cost and differentiation.
Design/methodology/approach
The hypotheses have been tested using data gathered via a questionnaire given to 277 Spanish manufacturing companies, and structural equation modelling has been used for the analysis.
Findings
The results show that competitive intensity is the most influential factor followed by business strategy. SC complexity does not seem to affect agility. Moreover, although the competitive environment variables affect the business strategy, the latter has no mediating effects between the competitive environment and SC agility, adaptability and alignment capabilities.
Originality/value
This study presents new insights into the environmental and strategic drivers linked to the implementation of SC agility, adaptability and alignment capabilities and offers guidelines to managers involved in SC management.

Abstract
Purpose
I aimed to obtain a deeper insight into the link between supplier involvement in product development (SIPD), supplier relationship resilience and company performance.
Design/methodology/approach
To collect data, a survey among 500 Polish manufacturing companies was conducted. I used quantitative methods (structural equation modeling) to test several research hypotheses referring to a single supplier–customer relationship. Thanks to the use of multi-construct measurement of SIPD and supplier relationship resilience, the study provides detailed research results on the topic.
Findings
Collaborative practices implemented during SIPD increase procurement flexibility and decrease redundancy in the relationship with the involved supplier. Communication during SIPD increases supplier flexibility and procurement flexibility. Increased supplier flexibility and increased procurement flexibility in the relationship with the involved supplier as well as collaborative practices during SIPD positively impact company performance. I confirmed the indirect effect between communication during SIPD and company performance when the mediators are supplier flexibility and procurement flexibility. Decreased redundancy in relationship with involved supplier does not impact company performance.
Practical implications
Supply chain managers need to rethink SIPD practice to effectively ensure supply chain resilience (SCRES), especially in the face of the contemporary global crisis and black swans affecting the supplier base. My article provides important managerial insights into drivers of SCRES and company performance.
Originality/value
To the best of my knowledge, this research is among the first to conclude that SIPD does not have an unequivocally positive or direct impact on supplier relationship resilience. The research fills the gap by analyzing the impact of SIPD on two main SCRES elements. The study examines supplier relationship resilience, understood as flexibility and redundancy elements, in a single supplier–buyer relationship perspective. Thus, the presented considerations go beyond the traditional understanding of flexibility and redundancy in supplier relationship management, that is through the prism of double or multi sourcing and having back up-suppliers.

Abstract
Purpose
The purpose of this paper is to present a quantitatively supported explanation of the intellectual development, the schools of thought and the sub-areas of the food cold chain (FCC) research to derive meaningful avenues for future research.
Design/methodology/approach
This study builds on bibliometric analysis and network analysis to systematically evaluate a sample of 1,189 FCC articles published over the past 25 years. The descriptive statistics and science mapping approaches using co-citation analysis were performed with VOSviewer software.
Findings
The findings reveal a state-of-the-art overview of the top contributing and influential countries, authors, institutions and articles in the area of FCC research. A co-citation analysis, coupled with content analysis of most co-cited articles, uncovered four underlying research streams including: application of RFID technologies; production and operation planning models; postharvest waste, causes of postharvest wastage and perishable inventory ordering polices and models; and critical issues in FCC. Current research streams, clusters and their sub-themes provided meaningful discussions and insights into key areas for future research in FCC.
Originality/value
This study might reshape practitioners’, researchers’ and policy-makers’ views on the multifaceted areas and themes in the FCC research field, to harness FCC’s benefits at both strategic and tactical level. Finally, the research findings offer a roadmap for additional research to yield more practical and modeling insights that are much needed to enrich the field.

Abstract
Purpose
Grounded in paradox theory, and with the objective of structuring and extending existing knowledge of conflicts of interest (e.g. trade-offs) in packaging logistics, the purpose of this paper is to identify categories of paradoxical tensions in packaging systems used in supply chains, and to develop a conceptual framework that describes these categories.
Design/methodology/approach
This research uses a theory building approach. It develops a conceptual framework of paradoxical tensions for packed products in supply chains. It revises and extends current knowledge in this domain by applying paradox theory from organisational research.
Findings
The paper develops a generic, conceptual framework that identifies, categorises and describes packed product paradoxes on two system levels: supply chain and company levels. The categories of paradoxes refer to performing, organising, belonging and learning.
Research limitations/implications
The framework provides a new theoretical explanation of conflicts of interest in packaging logistics in terms of paradoxical tensions related to packed products in supply chains. It structures and increases general understanding of such tensions within and between actors in a supply chain. The paper also discusses differences in terminology between tensions which are possible to settle and those which lead to paradoxes.
Practical implications
The framework provides a structure for analysing the organisational impact of strategic packaging decisions. It can help highlight different stakeholders' organisational constraints related to packaging.
Originality/value
The framework's systematic categorisation of four types of paradoxical tensions, with thorough descriptions of the meaning of packed product paradoxes of each type, offers an expanded and in-depth explanation of the organisational impacts of packed products in supply chains.

Abstract
Purpose
This study aims to investigate the association between the presence of a corporate social responsibility (CSR) committee and Sustainable Development Goals (SDGs) disclosure, as well as the moderating role of gender diversity in this relation.
Design/methodology/approach
The sample consists of 897 annual observations from 238 firms from Argentina, Brazil, Chile, Colombia, Mexico and Peru for 2018–2020. The data were collected from the Refinitiv database. The proposed model and hypotheses were tested using the feasible generalized least squares estimation technique with heteroscedasticity and panel-specific AR1 autocorrelation.
Findings
The results reveal that the presence of CSR committees positively influences the SDGs. Gender diversity positively moderates the relationship between CSR committees and SDGs. Leverage and firm size also positively impact the SDGs. On the other hand, board size and CEO duality negatively affect SDGs disclosure.
Research limitations/implications
This study extends the scope of stakeholder theory by suggesting that CSR committees and gender diversity enable a better relationship for the firm with its stakeholders.
Practical implications
The findings support policymakers and managers in improving sustainability disclosure. In addition, the results demonstrate the importance of CSR committees and gender diversity to meet the stakeholders' demands.
Social implications
This study demonstrates how firms can improve sustainability issues through gender diversity and CSR committees.
Originality/value
To the best of the authors’ knowledge, this study complements previous literature by being the first to examine the moderating effect of gender diversity on the association between CSR committees and SDGs disclosure in the Latin American context.

Abstract
Purpose
The purpose of this systematic review is to highlight some of the business model changes restaurants, bars and beverage producers undertook to modify their operations in order to not only stay in business but also to better serve their employees and communities during the COVID-19 crisis.
Design/methodology/approach
An analysis was conducted on 200 industry articles and categorized into three major themes: expansion of take-out/delivery, innovative practices, and community outreach/corporate support, each are further subdivided into additional themes. The systematic review is further supported by personal interviews with industry professionals.
Findings
This research finds that there were many different approaches used in adjusting business models in response to the dining restrictions put in place due to COVID-19. From these approaches, themes were developed which resulted in uncovering some suggestions such as developing contingency plans, being flexible and creative, eliminating menu items, investing in a communication platform and getting involved with local government. In addition, some practices operators should be mindful of such as selling gift cards and starting a crowdfund.
Research limitations/implications
This research provides a systematic analysis of business model changes that occurred due to COVID-19 dining restrictions. Researchers can use this information as a guide for further analysis on a specific theme introduced herein.
Practical implications
This research offers several practical implications which will assist the industry should another similar event occur in the future. The systematic analysis describes and documents some suggestions as well as practices to be mindful of in preparing contingency plans for the future.
Originality/value
This research documents an unprecedented time for the hospitality industry by examining how restaurant, bar and beverage producers around the country responded to COVID-19 restrictions. Distilling the multitude of information into succinct themes that highlight the business model changes that occurred will aid future research as well as operators.

Abstract
Rape culture, described as when “violence is seen as sexy and sexuality as violent” (Buchwald, Fletcher, & Roth, 1993, p. vii), exists online and offline (Henry & Powell, 2014). Much of the research on rape culture focuses on the experiences of heterosexual women, and few studies have explored rape culture in the context of dating apps. This chapter explores how men who have sex with men (MSM) understand and experience rape culture through their use of Grindr and similar dating apps. A thematic analysis of interviews with 25 MSM dating app users revealed problematic user behavior as well as unwanted sexual messages and images as common manifestations of rape culture on dating apps. Participants explained that rape culture extends beyond in-app interactions to in-person encounters, as evident by incidents of sexual violence that several participants had experienced and one participant had committed. Participants were unsure about the extent to which MSM dating apps facilitate rape culture but asserted that some apps enable rape culture more than others. This chapter demonstrates the importance of investigating sexual violence against people of diverse gender and sexual identities to ensure their experiences are not minimized, ignored, or rendered invisible.
