Abstract
Purpose
This paper aims to concentrate on recent innovations in flexible wearable sensor technology tailored for monitoring vital signals within the contexts of wearable sensors and systems developed specifically for monitoring health and fitness metrics.
Design/methodology/approach
In recent decades, wearable sensors for monitoring vital signals in sports and health have advanced greatly. Vital signals include electrocardiogram, electroencephalogram, electromyography, inertial data, body motions, cardiac rate and bodily fluids like blood and sweating, making them a good choice for sensing devices.
Findings
This report reviewed reputable journal articles on wearable sensors for vital signal monitoring, focusing on multimode and integrated multi-dimensional capabilities like structure, accuracy and nature of the devices, which may offer a more versatile and comprehensive solution.
Originality/value
The paper provides essential information on the present obstacles and challenges in this domain and provide a glimpse into the future directions of wearable sensors for the detection of these crucial signals. Importantly, it is evident that the integration of modern fabricating techniques, stretchable electronic devices, the Internet of Things and the application of artificial intelligence algorithms has significantly improved the capacity to efficiently monitor and leverage these signals for human health monitoring, including disease prediction.

Abstract
Purpose
Railways are a well-known example of complex critical infrastructure, incorporating socio-technical systems with humans such as drivers, signallers, maintainers and passengers at the core. The technological evolution including interconnectedness and new ways of interaction lead to new security and safety risks that can be realised, both in terms of human error, and malicious and non-malicious behaviour. This study aims to identify the human factors (HF) and cyber-security risks relating to the role of signallers on the railways and explores strategies for the improvement of “Digital Resilience” – for the concept of a resilient railway.
Design/methodology/approach
Overall, 26 interviews were conducted with 21 participants from industry and academia.
Findings
The results showed that due to increased automation, both cyber-related threats and human error can impact signallers’ day-to-day operations – directly or indirectly (e.g. workload and safety-critical communications) – which could disrupt the railway services and potentially lead to safety-related catastrophic consequences. This study identifies cyber-related problems, including external threats; engineers not considering the human element in designs when specifying security controls; lack of security awareness among the rail industry; training gaps; organisational issues; and many unknown “unknowns”.
Originality/value
The authors discuss socio-technical principles through a hexagonal socio-technical framework and training needs analysis to mitigate against cyber-security issues and identify the predictive training needs of the signallers. This is supported by a systematic approach which considers both, safety and security factors, rather than waiting to learn from a cyber-attack retrospectively.

Abstract
Purpose
Because of the global increase of climate change effects, floods are becoming more frequent and severer, especially in urban areas of coastal cities and islands where floodplains have turned into buildings because of rapid urbanisation, leading to a higher risk of damages. Urban heritage areas should be highly considered in the time of evacuation because of the vulnerability of streets and buildings and limitations on taking counteractions. Given these limitations, this study aims to propose a network of potential evacuation routes based on spatial configuration analysis of the heritage areas.
Design/methodology/approach
Penang Island's heritage site, namely, George Town, located on the northwest coast of Malaysia, is chosen as the case study. By using an approach of spatial configuration analysis using space syntax techniques in addition to considering the potential starting points for evacuation and flood risk map of the area, this study analysed the area's street network values for evacuation function during flood crisis time.
Findings
Potential evacuation routes were identified for flood disasters in the George Town heritage area. Furthermore, the proposed evacuation routes were evaluated in terms of time for evacuation by metric step-depth analysis of space syntax.
Originality/value
A few studies have focused on practical guidelines for evacuation routes based on spatial configuration analysis, an important yet neglected approach in this regard, especially concerning urban island areas. This study can contribute to providing strategies to reduce vulnerability and casualties in urban heritage areas.

Abstract
Purpose
To address the absence of Lean in transportation logistics in the digital era, this study aims to investigate the application of Lean transportation (LT) tools to reduce waste and facilitate the digital transformation of dedicated road transportation in the offshore industry.
Design/methodology/approach
The study adopts action research with a multimethod approach, including a scoping review, focus groups (FG) and participant observation. The research is conducted within the offshore supply chain of a major oil and gas company.
Findings
Implementing LT’s continuous improvement tools, particularly value stream mapping (VSM), reduces offshore transportation waste and provides empirical evidence about the intersection of Lean and digital technologies. Applying techniques drawn from organisational learning theory (OLT), stakeholders involved in VSM mapping and FGs engage in problem-solving and develop action plans, driving digital transformation. Waste reduction in loading and unloading stages leads to control actions, automation and process improvements, significantly reducing downtime. This results in an annual monetary gain of US$1.3m. The study also identifies waste related to human effort and underutilised digital resources.
Originality/value
This study contributes to theory and practice by using action research and LT techniques in a real intervention case. From the lens of OLT, it highlights the potential of LT tools for digital transformation and demonstrates the convergence of waste reduction through Lean and Industry 4.0 technologies in the offshore supply chain. Practical outputs, including a benchmarking questionnaire and a plan-do-check-act cycle, are provided for other companies in the same industry segment.

Abstract
Purpose
As aging populations lead to longer working lives and increasing automation threatens job security, maintaining lifelong employability is becoming a fundamental challenge for many individuals. The purpose of this study is to examine how lifelong employability can be maintained.
Design/methodology/approach
Based on the theoretical perspectives of both movement capital and selection, optimization and compensation (SOC) theories, we used large-scale survey data (N = 2,256) from three European countries to investigate strategies for preserving employability among aging workers. Specifically, we explored the perceived risk of automation, lifelong learner characteristics and self-efficacy for occupational mobility as boundary conditions that may shape the negative relationship between age and employability.
Findings
We found a negative relationship between age and employability, which was more pronounced when the perceived risk of automation was higher. Furthermore, lifelong learner characteristics and self-efficacy for occupational mobility mitigated the negative relationship, so that age was not related to employability if people possessed lifelong learner characteristics and were ready for a career change.
Originality/value
Our study implies the importance of investing in enhancing lifelong learner characteristics and self-efficacy for occupational mobility for older employees.

Abstract
Purpose
This paper covers the development of a novel defect model for concrete highway bridges. The proposed defect model is intended to facilitate the identification of bridge’s condition information (i.e. defects), improve the efficiency and accuracy of bridge inspections by supporting practitioners and even machines with digitalised expert knowledge, and ultimately automate the process.
Design/methodology/approach
The research design consists of three major phases so as to (1) categorise common defect with regard to physical entities (i.e. bridge element), (2) establish internal relationships among those defects and (3) relate defects to their properties and potential causes. A mixed-method research approach, which includes a comprehensive literature review, focus groups and case studies, was employed to develop and validate the proposed defect model.
Findings
The data collected through the literature and focus groups were analysed and knowledge were extracted to form the novel defect model. The defect model was then validated and further calibrated through case study. Inspection reports of nearly 300 bridges in China were collected and analysed. The study uncovered the relationships between defects and a variety of inspection-related elements and represented in the form of an accessible, digitalised and user-friendly knowledge model.
Originality/value
The contribution of this paper is the development of a defect model that can assist inexperienced practitioners and even machines in the near future to conduct inspection tasks. For one, the proposed defect model can standardise the data collection process of bridge inspection, including the identification of defects and documentation of their vital properties, paving the path for the automation in subsequent stages (e.g. condition evaluation). For another, by retrieving rich experience and expert knowledge which have long been reserved and inherited in the industrial sector, the inspection efficiency and accuracy can be considerably improved.

Abstract
Purpose
The proponents of cash waqf speak highly about its huge potential for mobilizing the third sector of the economy to fund the socio-economic development agenda. However, the under-collection issue has been characterizing the cash waqf movement globally. This study aims to examine how understanding the distinct cash waqf donating behavior across different generations has the potential to address the problem.
Design/methodology/approach
This study extends the theory of planned behavior by adding religiosity and knowledge variables into the standard model, using the partial least square structural equation modeling. A survey is conducted on 684 respondents representing the main provinces in Indonesia and four major generations (Baby Boomers [BB], Generations X, Y and Z).
Findings
Religiosity, Knowledge, Attitude, Subjective Norms and Perceived Behavioral Control directly or indirectly affect cash waqf intention. The effect is contingent on the characteristics of generations.
Research limitations/implications
This study covers only the Indonesian case with limited coverage of the more heterogeneous provinces in the country. The sample distribution for BB can also be enlarged.
Practical implications
Cash waqf institutions (government and private) should apply the dynamic segmenting strategy, where the diversification of the promotion, marketing, awareness and approaches are contingent on the different characteristics of each generation.
Originality/value
To the best of the authors’ knowledge, this is the first study evaluating the intergenerational determinants of Intention toward cash waqf, particularly in Indonesia.

Abstract
This chapter traces the origin of racism and reviews the historical and contemporary debates around race and racialisation in western thought. There are persistent disagreements surrounding the origin and nature of racism. Because of the evolution of racist ideas, behaviours and institutional practices and policies, there are various views about the meaning and analytical application of racism. This chapter explores how ideas of race – understood as innate and immutable human differences that can be classified and ranked hierarchically based on race – has emerged in western history and evolved over time. It examines how this has influenced social and political practices and associated policies across the evolution of modernity. The chapter specifically discusses the Atlantic slave trade and how it shaped the historical development of race and racism within the context of colonialism. It concludes with a discussion and critical review of some of the racist systems and policies which have been enforced across different multiracial countries.

Abstract
Purpose
It is critical for those who are engaged in the work of resisting the movement of academically restrictive policy to understand that it is a deliberate act on the part of conservatives to outlaw critical race theory (CRT) specifically, because it is a theoretical mechanism for discrediting the rhetorical foundations of their policy movement. The knee-jerk institutional courses of action to now defund initiatives and curriculum related equity, diversity and inclusion (EDI) represent what has always been a deeply rooted investment in white supremacy on the part of the institutions (Baldwin, 2021; Patel, 2021; Squire, 2021).
Design/methodology/approach
The author explores and defines the CRT tenets of interest convergence (Bell, 1980) and whiteness as property (Harris, 1993) in relation to EI (Fricker, 2007; Dotson, 2011) as frameworks for examining three EGOs in the region where these policies have become most dominant. All three are critical tools of analysis for understanding the stake the White conservative political elite have in EGOs, and the magnitude of EI these policies represent, and stand endorse in their rhetoric. Definitions of EI often rely on the work of Amanda Fricker’s (2013) text on the subject, but this paper is invested in the expansions of this theorization for speaking to the nature of the injustice that EGOs represent as a matter of historical trend, with grave implications for futures marked by continued oppression. Whiteness as property and interest convergence are points for explicating the dialectic and material aspects of issues of race and equity in this country; namely, how knowledge processes inherent to higher education sound even more alarms as EGOs become commonplace for college campuses.
Findings
To support the arguments laid out, the author provides a historical review of the settler-colonial foundations of higher education as an american institution. This is meant to provide contour to the image of postsecondary education that exists today. In accordance with this paper’s allegiance to CRT, many of the texts would be considered revisionist history (Delgado and Stefancic, 2023), which stray from dominant narratives of american comfort and speak more accurately to the experiences of minoritized populations. The author then applies the same analysis to the sociopolitical contexts of EGOs, and to policy language itself. Each section is closed with an explanation of its connection to tenets of CRT and EI so as to provide a thread to follow into the subsequent discussion section.
Research limitations/implications
In the first presentation of the early writings of this work, the author was lucky enough to be in community with Barbara Applebaum at the annual meeting for the American Educational Studies Association and engage in discourse surrounding EI and CRT applications to EGOs. In conversations surrounding the will in the willful ignorance that is exemplified in the movement of EGOs, the author had shared with Dr Applebaum the early thinking on how that will was the same force that brought together converging interests, which have continually forecasted interest divergence. This is commonly referred to as “political backlash.” The author had said something along the lines of: “if we follow the interest convergence, we can get in front of the subsequent political moves to turn the clocks on what was once celebrates progress.” This conversation planted the seed for what is the thesis of this paper. Interest convergence and divergence happen at the will of white populations because of the american truth of whiteness as property. In the context of higher education, this means that because educational pursuit has largely been white property, it has served as an arena for white populations to converge and diverge their interests with those of the minoritized. For example, the policies that drained federal funding for higher education in the 1970s were passed on the tails of a Civil Rights Movement that shook the very foundation of this country and expanded access to postsecondary education for racially minoritized groups (Berret, 2015).
Originality/value
Ensuring that this social construction is a matter of status quo has largely been the work of postsecondary institutions, and EGOs represent the most recent attempt at epistemically imposed inferiority. Explicit attention to the fact of higher education’s complicity and overall investment in the socialization of oppression is necessary to engage in transformative practice that resists anachronism. If higher education researchers and practitioners do not recognize the stake in both the presence and resistance to EGOs, there would likely be acts of resistance that will belie an act of interest convergence – and later divergence – on the part of the state.
