Abstract
Purpose
The purpose of this study is to propose a path-planning strategy based on the velocity-virtual spring method to realize collision-free tasks in dynamic environments and further improve the effect.
Design/methodology/approach
By considering factors such as the relative velocity and direction of dynamic obstacles, the repulsive force of the robot is improved, thereby enhancing the adaptability of the strategy and achieving flexible and effective avoidance against dynamic obstacles. The attraction formula has been designed to allow the robot to have better smooth changes and higher gradients near the target, helping robots better reach the target and follow formations. Moreover, to meet the demands of the various stages during the driving process, the null space behavioral control is used to solve multi-task conflict problems and strengthen formation coordination and control.
Findings
Comparison of the planning path and formation effects through simulation and physical experiments, the results of this study show that the algorithm proposed can successfully maintain formation stability and plan smooth and safe paths in static or dynamic environments.
Originality/value
This paper proposes a path-planning strategy based on the velocity-virtual spring method to plan collision-free paths for formation in dynamic environments.

Abstract
In this chapter, I will outline the labels of giftedness and underachievement and present the theoretical debates surrounding these labels. A historicist examination of these labels follows, highlighting how the gifted underachievement (GUA) label emerges through the negation of “giftedness.” Subsequently, I explore the concept of GUA and its negative connotations, stemming from the positive valuation inherent in the term “giftedness” and its implications for what is considered “normal.” This chapter also reviews perspectives on shifting the focus away from the individual within the current paradigm of labeling giftedness and explores insights from systemic thinking and symbolic interactionism (SI). The conclusion underscores the necessity of a symbolic interactionist perspective to address the gaps in research on the labeling of giftedness and underachievement. Finally, I propose a generic definition that can be used in GUA research in the light of SI.

Abstract
Purpose
This paper acknowledges the limitations of conventional heritage conservation, where the reuse of iconic modern houses as museums or exhibits often sacrifices their original residential function. We explore four aspects of the narrative approach – significance, reversibility, expandability and craftsmanship – to assess its potential for preserving and allowing change over time in the modern house.
Design/methodology/approach
Four iconic modern houses are analysed in this study: Villa Tugendhat-Brno frozen as a museum house, Chabot Museum-Rotterdam refunctioned as an art museum, Haus Schminke-Löbau used as a guest house and Maison Guiette-Antwerpen still in use. Employing aspects of the narrative approach (Walter, 2020a, b), the analysis evaluates recent heritage management practices in preserving the building’s multifaceted history and associated perspectives.
Findings
The narrative approach in heritage conservation values the evolving significance of cultural heritage by recognising different perspectives and preserving the traces of past changes. It promotes sustainability by enabling adaptive reuse while preserving historical integrity by respecting past and future heritage. Despite its obvious weaknesses, such as potential subjectivity, the dilution of valuations and the loss of historic fabric, it particularly responds to the ephemeral nature and challenges of modernity.
Originality/value
The cross-case analysis of practical conservation approaches, encompassing varied strategies for conservation and adaptive reuse, offers valuable insights for theorizing the significance of modernist architecture for both the present and future.

Abstract
Purpose
The purpose of this paper is to examine recovery through lived experience. It is part of a series that explores candid accounts of addiction and recovery to identify important components in the recovery process.
Design/methodology/approach
The G-CHIME model comprises six elements important to addiction recovery (growth, connectedness, hope, identity, meaning in life and empowerment). It provides a standard against which to consider addiction recovery. It has been used in this series, as well as in the design of interventions that improve well-being and strengthen recovery. In this paper, a first-hand account is presented, followed by a semi-structured e-interview with the author of the account. Narrative analysis is used to explore the account and interview through the G-CHIME model.
Findings
This paper shows that addiction recovery is a remarkable process that can be effectively explained using the G-CHIME model. The significance of each component in the model is apparent from the account and e-interview presented.
Originality/value
Each account of recovery in this series is unique, and as yet, untold.

Abstract
This chapter delves into the specific heuristics, biases, and cognitive errors that often arise during decision-making processes in healthcare. It explores how specific mental shortcuts can lead to inconsistencies and irrationalities. Key concepts include statistical evaluation errors, such as the base rate fallacy and the law of large numbers, and causal inference issues like regression to the mean and omitted variables. This chapter also covers common cognitive biases, such as confirmation bias, optimism bias, action bias, halo effect, overdiagnosis, etc., which influence medical professionals and patients in interpreting information and deciding. Recognition of such biases can enhance medical decision outcomes as well as improving the communication between stakeholders.

This study aims to explore how social support has reshaped the care of older adults living alone in northeast Thailand during the COVID-19 pandemic.
Abstract
Purpose
This study aims to explore how social support has reshaped the care of older adults living alone in northeast Thailand during the COVID-19 pandemic.
Design/methodology/approach
This study used a qualitative method using a narrative gerontological perspective with a descriptive design. Purposive sampling was conducted from 20 in-depth narrative interviews between November 2021 and February 2022 in Maha Sarakham province, northeast Thailand. Data transcriptions were performed using a narrative analytical process.
Findings
The in-depth narrative interviews indicated that older adults living alone during the coronavirus pandemic valued a comfortable life, a sense of place, favourable living arrangements, self-reliance, life goals and meaningful life. The gerontological analysis showed that social support for older adults living alone included a social safety net, networking, supporting needs, physical care and mental health responses to the COVID-19 pandemic.
Originality/value
To the best of the authors’ knowledge, this is the first qualitative narrative gerontological study to explore how social support reshaped the care of older adults living alone during the COVID-19 pandemic in northeast Thailand.

Abstract
Purpose
Social avoidance disorders can be disruptive to the individual as they begin to over-manage their lives, at times avoiding social and work commitments. A potential therapeutic approach is exposure therapy and a virtual reality (VR) treatment approach, gameChange VR, has been developed. This provides an opportunity to test their fears in virtual environments. This study aims to investigate the feasibility of using this VR approach to treat people with social avoidance problems within a secure mental health setting.
Design/methodology/approach
Nine participants completed the gameChange VR sessions. Participants received 30-minute VR sessions for up to six weeks using selected scenarios at five levels of difficulty. Patients’ comments and behaviours were noted and clinical staff also provided feedback on their observations of patients’ use and experience with VR.
Findings
Overall, patients felt that the gameChange VR helped them to build their confidence and reduce their overall anxiety as they became more comfortable with the equipment. Both patients and staff generally found the intervention easy to use and the staff reported an overall high level of engagement among the participants. The key issues raised largely related to technical and safety issues.
Originality/value
While a previous study was carried out using gameChange VR with an outpatient cohort, this was the first using an inpatient group in a secure mental health setting. It has demonstrated that the intervention is viable in this setting, although further studies are required to identify the specific patient population that would benefit optimally from the therapy.
