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.

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.

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.

This paper proposes a path-planning strategy based on the velocity-virtual spring method to plan collision-free paths for formation in dynamic environments.

The purpose of this paper is to challenge some of the stigma that surrounds voice-hearing. This excerpt of creative writing comes from a self-published memoir, that tells a young woman's story of her struggle with hearing voices, and her journey through the mental health system.

Writing provides a useful filter for Emily to reflect on what it was like to receive various diagnoses, treatments and therapies when she was hearing voices.

Emily learns to accept that she hears voices. This is a journey that takes all of her new-found strength and resolve.

This memoir describes voices (auditory verbal hallucinations) that need to be more widely understood.

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.

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.

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.

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.

This paper aims to explore the efforts of four American women living with psychosis to chart their recovery process in published memoirs.

This paper looks at the different types of stigma that the patient-authors claim to encounter.

The author discusses the impact that the patient-authors see stigma as having on their recovery, and why they need artistic spaces to express themselves.

The memoirs offer a space for the women to revisit their memories of psychosis, and to achieve at least a partial acceptance of these experiences.

This study draws on the Social Process of Leadership (SPL) to identify the necessary behavioural leadership characteristics for trust-building in virtual crisis environments.

The study employs an in-depth qualitative case-study approach that is embedded in local contexts. Multiple sources of data – organisational documents, in-depth qualitative interviews, observational evidence and field notes – were used in the study. Interviews were informed by a purposeful sampling strategy and were semi-structured. This allowed the interviewer to use prompts to follow up with unanticipated issues raised by participants. Thematic analysis was conducted using NVivo.

Three key themes (related to how leaders nurture trust in virtual and crisis contexts) emerged from the data. These relate to nurturing trust by (1) optimising and providing a clear vision through reconfigured and personalised communication structures; (2) minimising uncertainty, optimising and modelling values-based behaviours and (3) enhancing adaptability and performance.

The study extends the applicability of this theoretical approach to remote workplaces. It also contributes to the literature on crisis leadership by showcasing how leaders’ crisis responses based on SPL help organisations navigate disruptions. Limitations regarding the small sample size and the one case study context exist.

Organisations should invest in leadership and resilience and build strong remote/hybrid working models in preparation for future crises.

Despite the growing popularity of SPL, there is limited work on how leaders implement SPL processes to build and maintain trust in virtual workplaces. Furthermore, SPL has not yet been applied in highly disruptive work contexts, like those created by the pandemic.

The Canadian government legalized cannabis in 2018 and funded harm reduction campaigns to educate youth about the risks. Cannabis can contribute to psychosis in vulnerable populations, and consumption is common among youth in Early Psychosis Intervention (EPI) programs. The purpose of this study is to understand the views of youth in EPI programs on the risks related to cannabis and methods to reduce those risks.

A qualitative design and thematic analysis were used to understand the perspectives of youth in EPI programs (n = 15) towards cannabis risks and harm reduction.

Participants associated Δ−9 tetrahydrocannabinol (THC) with problems related to cognition, psychosis, respiration, addiction, motivation, finances, relationships and anxiety. Cannabidiol (CBD) was believed to be safe and risk-free. To reduce the risks associated with THC, participants suggested using in moderation, delaying use, using CBD over THC, accessing legal sources, avoiding high THC dosages and using non-combustible methods.

Participants self-selected to participate, were psychiatrically stable and may not represent youth in EPI programs with more severe psychotic symptoms.

Assessing risk perceptions, motives for use and perspectives towards the cannabis and psychosis connection can reveal educational needs. CBD may offer a harm reduction option for EPI clients wanting to decrease THC intake, though more research is needed and adverse effects should be explained. Educational campaigns should disseminate the connection between cannabis and psychosis to facilitate early intervention.

This study adds to the literature by highlighting knowledge of harm reduction methods and gaps in risk awareness among EPI program youth.
