Abstract
Purpose
This paper aims to present a novel lightweight distribution grid operating robot system with focus on lightweight and multi-functionality, aiming for autonomous and live-line maintenance operations.
Design/methodology/approach
A ground-up redesign of the dual-arm robotic system with 12-DoF is applied for substantial weight reduction; a dual-mode operating control framework is proposed, with vision-guided autonomous operation embedded with real-time manual teleoperation controlling both manipulators simultaneously; a quick-swap tooling system is developed to conduct multi-functional operation tasks. A prototype robotic system is constructed and validated in a series of operational experiments in an emulated environment both indoors and outdoors.
Findings
The overall weight of the system is successfully brought down to under 150 kg, making it suitable for the majority of vehicle-mounted aerial work platforms, and it can be flexibly and quickly deployed in population dense areas with narrow streets. The system equips with two dexterous robotic manipulators and up to six interchangeable tools, and a vision system for AI-based autonomous operations. A quick-change tooling system ensures the robot to change tools on-the-go without human intervention.
Originality/value
The resulting dual-arm robotic live-line operation system robotic system could be compact and lightweight enough to be deployed on a wide range of available aerial working platforms with high mobility and efficiency. The robot could both conduct routine operation tasks fully autonomously without human direct operation and be manually operated when required. The quick-swap tooling system enables lightweight and durable interchangeability of multiple end-effector tools, enabling future expansion of operating capabilities across different tasks and operating scenarios.

Abstract
Purpose
There is a renowned interest in adaptability as an important principle for achieving circularity in the built environment. Circular building adaptability (CBA) could enable long-term building utilisation and flexible use of space with limited material flows. This paper identifies and analyses design strategies facilitating CBA to propose a framework for enhancing the implementation of the concept.
Design/methodology/approach
Interviews were conducted with professionals experienced in circular building design to explore the questions “How do currently applied design strategies enable CBA?” and “How can CBA be implemented through a conceptual design framework?”. The interviews encircled multi-residential building examples to identify currently applied circular design strategies. The interviews were analysed through qualitative content analysis using CBA determinants as a coding framework.
Findings
The results show that all ten CBA determinants are supported by design strategies applied in current circular building design. However, some determinants are more supported than others, and design strategies are often employed without explicitly considering adaptability. The design strategies that enable adaptability offer long-term solutions requiring large-scale modifications rather than facilitating low-impact adaptation by dwelling occupants. The proposed conceptual design framework could aid architects in resolving these issues and implementing CBA in their circular building design.
Originality/value
This paper’s contribution to CBA is threefold. It demonstrates design strategies facilitating CBA, proposes a conceptual design framework to apply the concept and identifies the need for a more comprehensive application of available adaptability strategies.

Abstract
Purpose
Connecting autonomous drones to ground operations and services is a prerequisite for the adoption of scalable and sustainable drone services in the built environment. Despite the rapid advance in the field of autonomous drones, the development of ground infrastructure has received less attention. Contemporary airport design offers potential solutions for the infrastructure serving autonomous drone services. To that end, this paper aims to construct a framework for connecting air and ground operations for autonomous drone services. Furthermore, the paper defines the minimum facilities needed to support unmanned aerial vehicles for autonomous logistics and the collection of aerial data.
Design/methodology/approach
The paper reviews the state-of-the-art in airport design literature as the basis for analysing the guidelines of manned aviation applicable to the development of ground infrastructure for autonomous drone services. Socio-technical system analysis was used for identifying the service needs of drones.
Findings
The key findings are functional modularity based on the principles of airport design applies to micro-airports and modular service functions can be connected efficiently with an autonomous ground handling system in a sustainable manner addressing the concerns on maintenance, reliability and lifecycle.
Research limitations/implications
As the study was limited to the airport design literature findings, the evolution of solutions may provide features supporting deviating approaches. The role of autonomy and cloud-based service processes are quintessentially different from the conventional airport design and are likely to impact real-life solutions as the area of future research.
Practical implications
The findings of this study provided a framework for establishing the connection between the airside and the landside for the operations of autonomous aerial services. The lack of such framework and ground infrastructure has hindered the large-scale adoption and easy-to-use solutions for sustainable logistics and aerial data collection for decision-making in the built environment.
Social implications
The evolution of future autonomous aerial services should be accessible to all users, “democratising” the use of drones. The data collected by drones should comply with the privacy-preserving use of the data. The proposed ground infrastructure can contribute to offloading, storing and handling aerial data to support drone services’ acceptability.
Originality/value
To the best of the authors’ knowledge, the paper describes the first design framework for creating a design concept for a modular and autonomous micro-airport system for unmanned aviation based on the applied functions of full-size conventional airports.

Abstract
Purpose
The application of circular building adaptability (CBA) in adaptive reuse becomes an effective action for resource efficiency, long-lasting usability of the built environment and the sped-up transition to a circular economy (CE). This paper aims to explore to which extent CBA-related strategies are applied in adaptive reuse projects, considering enablers and obstacles.
Design/methodology/approach
A stepwise theory-practice-oriented approach was followed. Multiple-case studies of five circular adaptive reuse projects in The Netherlands were investigated, using archival research and in-depth interviews. A cross-case analysis of the findings was deductively conducted, to find and replicate common patterns.
Findings
The study revealed that configuration flexibility, product dismantlability and material reversibility were applied across the case studies, whereas functional convertibility and building maintainability were less applied. Low cost of material reuse, collaboration among team members and organisational motivation were frequently observed enabling factors. Lack of information, technical complexities, lack of circularity expertise and infeasibility of innovative circular solutions were frequently observed obstacles to applying CBA.
Practical implications
This paper provides practitioners with a set of CBA strategies that have been applied in the real world, facilitating the application of CBA in future adaptive reuse projects. Moreover, this set of strategies provides policymakers with tools for developing supportive regulations or amending existing regulations for facilitating CE through adaptive reuse.
Originality/value
This study provides empirical evidence on the application of CBA in different real-life contexts. It provides scholars and practitioners with a starting point for further developing guiding or decision-making tools for CBA in adaptive reuse.

Abstract
Purpose
Environmental uncertainty (EU) and firm size (FS) generate inertial forces that can push small and medium-sized enterprises (SMEs) to emphasize either exploration or exploitation. In this article, the authors explore how structural (e.g. formal processes, control and discipline) and social (e.g. employee support and decision-making involvement) managerial instruments counteract such inertial forces and enable SME ambidexterity. Building on the organization-context literature, the authors propose a model in which EU and firms' size moderate the relationship between structural and social managerial instruments on SME ambidexterity.
Design/methodology/approach
The authors examined a moderation model using surveys of chief executive officers (CEOs) and performance archival data from 237 Chilean SMEs.
Findings
The authors find that the positive effect of structure on SME ambidexterity decreases with FS. In contrast, social instruments have a positive effect on ambidexterity for larger firms, especially for those operating in uncertain environments. In cases in which EU and firms' size reinforce the exploration or exploitation tendencies of SMEs, structural and social instruments play a complementary role in achieving ambidexterity.
Originality/value
The authors contribute by proposing a contingent mix of structural and social instruments to enable SME ambidexterity. These results inform policymakers and SME managers by suggesting strategies to promote ambidexterity based on firms' size and EU.

Abstract
Purpose
Peanut skins are an agro-waste product with no commercial value. The purpose of this paper is to evaluate peanut skin as a natural dyestuff and to determine if this natural dye could be used in the dyeing of some Egyptian cotton cultivars.
Design/methodology/approach
The methodology consists of several steps; dye extraction procedure from peanut skin through aqueous extraction, then dyeing optimized using simultaneous mordanting using alum. Finally, dyed cotton has been subjected to different textile laboratory tests, for example, color measurements and mechanical properties. Color-fastness was determined on Egyptian cotton fabric. The peanut skin as a source of natural dye and the dyed cotton sample were characterized by fourier transform infrared spectroscopy (FTIR) analysis.
Findings
It was found that the natural dye extracted from peanut skin has an affinity for cotton samples and showed high dyeability with a unique color shade, good color strength and very good fastness.
Originality/value
The novelty of this paper is the extraction of color from the peanut's outer skin which is discarded as waste such as agro-waste of the agricultural process which can be used as a natural dye in the textile industry and applied to dyeing some Egyptian cotton fibers from different genotypes.

Abstract
The smart city paradigm has evolved from a perspective focused on technological infrastructures to an approach in which the effects of the technological apparatus improve the quality of life of people, urban resilience, urban sustainability, and health, by introducing the concept of smart and sustainable city 3.0. In this chapter, the authors evaluate mobility as a key aspect of improving the environmental, social, and economic well-being of communities under the central concept of smart and sustainable city 3.0. To this end, the authors underline the link between mobility, the Sustainable Urban Mobility Plans (SUMP), and environmental health. Then, the authors outline (i) the mobility requirements to be met from a smart perspective on environmental health and how (ii) the SUMPs can be considered as the basic tool for connecting smartness with mobility and environmental health. Finally, the results obtained will be discussed, and future directions of this research will be illustrated.

Abstract
Purpose
This study aims to investigate the effects of nomophobia in the organizational environment, and the authors developed a research model consisting of the construct's loneliness, depression and anxiety. The growing competitiveness of the market and the need of many companies regarding the availability of employees demand attention.
Design/methodology/approach
The authors surveyed 454 Brazilian respondents and used covariance-based structural equation modeling to analyze the survey results. The model’s hypotheses proved significant, confirming the relationships proposed by the theoretical model.
Findings
Loneliness and depression, rather than anxiety, explained the influence of nomophobia on individuals’ ability to communicate when inserted in the professional context. Individuals were most likely to have high nomophobia incorporate psychological traits that involve emotional instability, and could benefit from the connection between people in a social group.
Practical implications
This study confirms that nomophobia can be a situational phobia evoked by the unavailability of a smartphone or by the idea of not having it, not being able to use it or losing it, even within the business context.
Social implications
The increase in loneliness and depression indicates a deficiency in the face of the smartphone’s benefits.
Originality/value
This paper provides contributions that seek to understand the effect of symptoms from smartphones in the workplace, also indicating that users may cause vulnerability. Companies can prevent vulnerability by creating policies prohibiting their use in the organization’s context and developing healthy habits that do not lead to addiction.

Abstract
Purpose
Because of the use of digital technologies in smart cities, municipalities are increasingly facing issues related to urban data management and are seeking ways to exploit these huge amounts of data for the actualization of data driven services. However, only few studies discuss challenges related to data driven strategies in smart cities. Accordingly, the purpose of this study is to present data driven approaches (architecture and model), for urban data management needed to improve smart city planning and design. The developed approaches depict how data can underpin sustainable urban development.
Design/methodology/approach
Design science research is adopted following a qualitative method to evaluate the architecture developed based on top-level design using a case data from workshops and interviews with experts involved in a smart city project.
Findings
The findings of this study from the evaluations indicate that the identified enablers are useful to support data driven services in smart cities and the developed architecture can be used to promote urban data management. More importantly, findings from this study provide guidelines to municipalities to improve data driven services for smart city planning and design.
Research limitations/implications
Feedback as qualitative data from practitioners provided evidence on how data driven strategies can be achieved in smart cities. However, the model is not validated. Hence, quantitative data is needed to further validate the enablers that influence data driven services in smart city planning and design.
Practical implications
Findings from this study offer practical insights and real-life evidence to define data driven enablers in smart cities and suggest research propositions for future studies. Additionally, this study develops a real conceptualization of data driven method for municipalities to foster open data and digital service innovation for smart city development.
Social implications
The main findings of this study suggest that data governance, interoperability, data security and risk assessment influence data driven services in smart cities. This study derives propositions based on the developed model that identifies enablers for actualization of data driven services for smart cities planning and design.
Originality/value
This study explores the enablers of data driven strategies in smart city and further developed an architecture and model that can be adopted by municipalities to structure their urban data initiatives for improving data driven services to make cities smarter. The developed model supports municipalities to manage data used from different sources to support the design of data driven services provided by different enterprises that collaborate in urban environment.

Abstract
Purpose
This study explores the difference in occupants' satisfaction with biophilic features in high-rises, townhouses, and villas in Dubai to identify new strategies that promote more human-nature connections. The study also serves as a benchmark for applying Biophilic Design in the Gulf region and bridging between biophilic theory and practice.
Design/methodology/approach
A mixed-mode approach was used, combining surveys from occupants and interviews with experts (3 policymakers, a developer, and a biophilic design educator). The survey collected occupants' satisfaction and acceptance of proposed strategies, and the interviews validated the potentially accepted solutions.
Findings
The results indicated high overall satisfaction with biophilic features despite neutral/low satisfaction with specific features. In high-rise buildings, respondents showed high acceptance for different proposed strategies; 76.4% for adaptive control of balconies by season, 82.7% for utilizing outdoor roof gardens, 78.9% for indoor gardens, and 71.8% for vertical farming. Additionally, respondents accepted social strategies; 63.6% agreed to join clubs promoting environmental events, and 75.4% accepted participating in outdoor recreational activities accompanied by local environmental education. The interviews showed an inclination toward incentive programs instead of obligations.
Originality/value
Unlike former studies that assessed indoor environmental qualities without referring to biophilic theory or limited reference to biophilic design, this study provides a novel approach for bridging theory and practice by integrating biophilic design into residential buildings for Dubai's future developments. Additionally, the authors suggest validated proposals to enhance the occupants' biophilic living experience, serving as a benchmark for biophilic application in the Gulf region.
