Abstract
Purpose
Robots face fundamental challenges in achieving reliable and stable operations for complex home service scenarios. This is one of the crucial topics of robotics methods to imitate human beings’ advanced cognitive characteristics and apply them to solve complex tasks. The purpose of this study is to enable robots to have the ability to understand the scene and task process in complex scenes and to provide a reference method for robot task programming in complex scenes.
Design/methodology/approach
This paper constructs a task modeling method for robots in complex environments based on the characteristics of the perception-motor memory model of human cognition. In the aspect of episodic memory construction, the task execution process is included in the category of qualitative spatio-temporal calculus. The topology interaction of objects in a task scenario is used to define scene attributes. The task process can be regarded as changing scene attributes on a time scale. The qualitative spatio-temporal activity graphs are used to analyze the change process of the object state with time during the robot task execution. The tasks are divided according to the different values of scene attributes at different times during task execution. Based on this, in procedural memory, an object-centered motion model is developed by analyzing the changes in the relationship between objects in the scene episode by analyzing the scene changes before and after the robot performs the actions. Finally, the task execution process of the robot is constructed by alternately reconstructing episodic memory and procedural memory.
Findings
To verify the applicability of the proposed model, a scenario where the robot combines the object (one of the most common tasks in-home service) is set up. The proposed method can obtain the landscape of robot tasks in a complex environment.
Originality/value
The robot can achieve high-level task programming through the alternating interpretation of scenarios and actions. The proposed model differs from traditional methods based on geometric or physical feature information. However, it focuses on the spatial relationship of objects, which is more similar to the cognitive mechanism of human understanding of the environment.

Abstract
Purpose
This study aims to analyse how first-year undergraduate audiovisual communication students assess the credibility and reliability of information on Wikipedia in Basque and analyse whether the experience of being a Wikipedia editor helps to improve students’ perceptions of Wikipedia’s trustworthiness. The purpose of this project was to help students to better understand the credibility mechanisms of Wikipedia in Basque regarding the work of editing and creating entries. Do students’ perceptions about how reliable Wikipedia is change if they receive training as Wikipedia content editors and understand Wikipedia’s credibility mechanisms? What are their perceptions about the credibility of Wikipedia?
Design/methodology/approach
The authors observed and analysed students’ behaviour and perceptions when creating Wikipedia articles and learning about the process of evaluating Wikipedia. This research was carried out at [masked for review] over four consecutive years, where 188 students in the Degree Programme in Audiovisual Communication participated through a questionnaire and in-depth interviews.
Findings
After the experience of creating content on Wikipedia and learning about Wikipedia’s credibility mechanisms experientially, the majority of students reported that their perception of Wikipedia’s credibility had increased, and 70% of students believed Wikipedia to be reliable or more reliable than expected. A smaller number of students stated that understanding Wikipedia’s editing processes decreased their perception of Wikipedia’s credibility.
Practical implications
This project will lead to a better understanding of the performance of students in editing content on Wikipedia and of the impact that this editing experience has on students’ perceptions of credibility with respect to Wikipedia. It will make it possible to better incorporate Wikipedia content editing into the learning processes of students and citizens. This study provides interesting keys to improving the reliability and credibility of Wikipedia among students.
Social implications
As the study examined Basque Wikipedia, it has important social implications since Basque is a minority language and Wikipedia is the main sources of information for students who study in Basque.
Originality/value
The authors have been analysing the credibility of information in general and that of information on Wikipedia in particular since 2010. Based on this experience, the authors decided to design this study so that it was carried out while the students were creating and editing Wikipedia content as part of a project in their educational curriculum. Furthermore, the study expands the body of research carried out to date by incorporating the perspectives of media studies students.

Abstract
Purpose
By older adulthood, the majority of individuals will have experienced at least one traumatic event. Trauma-informed care (TIC) is proposed to improve effectivity of health-care provision and to reduce likelihood of services causing retraumatisation. This study aims to assess the effectiveness of staff training in TIC in older adult services.
Design/methodology/approach
TIC training was delivered across eight Older Adult Community Mental Health Teams in the same UK organisation. Questionnaires were administered before and after training: a psychometrically robust measure, the Attitudes Related to Trauma-Informed Care, was used to assess TIC-related attitudes, and a service-developed scale was used to measure changes in TIC competence. Data was analysed using linear mixed effects modelling (LMM). Qualitative data regarding the impact of training was gathered one month after training through a free-text questionnaire.
Findings
There were 45 participants, all of whom were white British. LMM on pre- and post-data revealed that staff training significantly increased competencies across all measured TIC domains. Overall, staff attitudes were also significantly more trauma-informed after training. Qualitatively, staff identified time as the only additional resource required to deliver the skills and knowledge gained from training.
Practical implications
Training was found to be effective in increasing TIC-related skills and attitudes. Organisations aiming to become trauma-informed should consider staff training as one aspect of a wider development plan.
Originality/value
To the best of the authors’ knowledge, this paper is the first to examine TIC training for staff working in Older Adults Mental Health Services. Recommendations for services aiming to develop a trauma-informed culture have been provided.

Abstract
Purpose
This study aims to evaluate the effect of Alpha-Stim Anxiety, Insomnia and Depression (AID) cranial electrotherapy stimulation (CES) on anxiety, depression and health-related quality of life for primary care social prescribing service patients with anxiety symptoms.
Design/methodology/approach
Open-label patient cohort design with no control group. A total of 33 adult patients (average age 42 years) completed six weeks of Alpha-Stim AID use. Pre- and post-intervention assessment with participant self-report measures: Patient Health Questionnaire (PHQ-9), Generalised Anxiety Disorder (GAD-7) and European Quality of Life Five Dimension (EQ-5D-5L).
Findings
Reliable improvement and remission rates, respectively, were 53.39% and 33.3% for GAD-7; 46.7% and 29.5% for PHQ-9. There was a significant improvement in GAD-7 and PHQ-9 with large effect sizes. EQ-5D-5L results showed significant improvements in health-related quality of life. Perceived quality of life increased by 0.17 on the health index score, with the intervention adding 1.68 quality-adjusted life years (QALYs).
Practical implications
Alpha-Stim AID can be delivered through a primary health-care social prescribing service and most patients will use as prescribed and complete treatment course. Alpha-Stim AID CES may be an effective anxiety and depression treatment for people with anxiety symptoms. The widespread roll-out of Alpha-Stim AID in health-care systems should be considered.
Originality/value
To the best of the authors’ knowledge, this is the first study to respond to the UK’s National Institute for Health and Care (NICE) request for the collection of real-world data to understand better Alpha-Stim AID in relation to people’s treatment uptake, response rates and treatment completion rates (NICE, 2021).

Abstract
Purpose
In view of a lack of evidence on the effectiveness of climate change education (CCE) in China, this study aims to evaluate if a CCE course newly designed based on research recommendations and implemented with established pedagogy was effective in changing the beliefs and attitudes of first-year science students.
Design/methodology/approach
This study took a simple longitudinal approach with surveys administered at the beginning and the end of the course and the differences in the responses analyzed with nonparametric statistical analyses.
Findings
The results showed that the course produced significant changes in the beliefs concerning the anthropogenic causes of climate change and vulnerability to its impacts, which results in inequality of the impacts received. However, the course did not produce significant attitudinal changes among the students. Spearman’s correlation, which affirmed the belief–attitude association, revealed that the students already had desirable attitudes toward climate change and these attitudes had not been reinforced. The students’ perception of the importance of local government in climate action increased by the end of the course. Multimedia-aid learning, debates and discussions were useful in conveying the concepts of responsibility, ethics and vulnerability, but the addition of student-led community projects will increase personal significance of the course.
Research limitations/implications
This study is instrumental for the development of a regional model of CCE in the mainstreaming of education for sustainable development in China, knowing that the regional approach is crucial to address the nuances in climate change knowledge, hence conceptions and beliefs across regions and, even, between different sectors of a region. This regional experience could also serve as a reference for other similar settings, particularly those of the developing countries.
Originality/value
This study presents one of the very few studies dedicated to gauging the effects of CCE in China, particularly of a newly developed climate change course, on the beliefs and attitudes of students. This permits pedagogical development and continuous improvement of CCE in China.

Abstract
Purpose
This study aims to predict China's carbon emission intensity and put forward a set of policy recommendations for further development of a low-carbon economy in China.
Design/methodology/approach
In this paper, the Interaction Effect Grey Power Model of N Variables (IEGPM(1,N)) is developed, and the Dragonfly algorithm (DA) is used to select the best power index for the model. Specific model construction methods and rigorous mathematical proofs are given. In order to verify the applicability and validity, this paper compares the model with the traditional grey model and simulates the carbon emission intensity of China from 2014 to 2021. In addition, the new model is used to predict the carbon emission intensity of China from 2022 to 2025, which can provide a reference for the 14th Five-Year Plan to develop a scientific emission reduction path.
Findings
The results show that if the Chinese government does not take effective policy measures in the future, carbon emission intensity will not achieve the set goals. The IEGPM(1,N) model also provides reliable results and works well in simulation and prediction.
Originality/value
The paper considers the nonlinear and interactive effect of input variables in the system's behavior and proposes an improved grey multivariable model, which fills the gap in previous studies.

Abstract
Purpose
This paper aims to explore examine the therapeutic potential of head-mounted display (HMD)-based Virtual Reality Relaxation Therapy (VRRT) sessions for people individuals with dementia in Jordan.
Design/methodology/approach
This cross-sectional survey recruited 75 dementia-diagnosed elderly individuals from three Jordanian care homes. A VRRT intervention comprising 10 tailored RT sessions held over the course of five weeks was administered to the participants. Apathy, cognitive performance, anxiety and depression were evaluated before and after the intervention to determine any changes. The Person-Environment Apathy Rating Scale's (PEARS) Arabic translation's validity and reliability were also evaluated.
Findings
The VRRT intervention yielded noteworthy results in reducing apathy, as indicated by a substantial decrease in PEARS scores from 17.20 to 11.15. The findings of the study revealed that the participants demonstrated enhanced cognitive abilities, as evidenced by a significant rise in their Saint Louis University Mental Status ratings, which increased from 15.11 to 19.70. The levels of anxiety and depression exhibited a significant decrease subsequent to the implementation of VRRT, with anxiety levels decreasing from 13.66 to 8.23 and depression levels decreasing from 13.62 to 9.33. Furthermore, a notable 70% of participants demonstrated statistically significant decreases in indifference.
Practical implications
This study makes a significant contribution to the advancement of innovative treatment approaches aimed at addressing the needs of the aging population, hence enhancing health outcomes and raising the quality of care in Jordan.
Originality/value
The effectiveness of VRRT in reducing apathy among Jordanian senior citizens residing in nursing homes has not yet been fully investigated. Therefore, this paper seeks to assess the effectiveness of HMD-based VRRT by conducting pre- and post-intervention evaluations. This research aims to provide valuable insights into the applicability and significance of VRRT in the Jordanian context, contributing to the development of culturally appropriate and cutting-edge therapeutic interventions for older individuals in Jordan. Through this study, the authors aim to promote improved health and elevated standards of care for this population.

Abstract
Purpose
There is a lot of talk about the electric car today, but these vehicles are not new. Indeed, thebeginning of the 20th century saw electricity and the automobile take hold in North American society, so that by 1910, the electric car was everywhere. Until the turn of the 1920s, a new era dawned for transportation in the USA, but without the electric car. The purpose of this study is to question Why did it happen.
Design/methodology/approach
This paper develops such a comparison, not of the cars themselves, through a detailed engineering analysis, but rather of the marketing of electric vehicles in the USA in 1910 and 2010, as it appeared in the marketing strategies of the manufacturers.
Findings
There are many technical and economic reasons for this, but not only; there are also commercial strategy reasons. The position of manufacturers, especially through advertising and the press, can tell us about this golden age of the electric car, what precipitated its fall, and its reappearance a century later.
Originality/value
It is a comparison of images, of how electric vehicles had been and are proposed to the public, through the exploration of mainly promotional material and newspaper articles.

Abstract
Purpose
Clinical staff working in mental health services experience high levels of work-related stress, burnout and poor well-being. Increased levels of stress, burnout, depression and anxiety and poorer mental well-being among health-care workers are associated with more sick days, absenteeism, lower work satisfaction, increased staff turnover and reduced quality of patient care. Virtual reality (VR) relaxation is a technique whereby experiences of pleasant and calming environments are accessed through a head-mounted display to promote relaxation. The purpose of this paper is to describe the design of a study that assesses the feasibility and acceptability of implementing a multi-session VR relaxation intervention amongst mental health professionals, to improve their relaxation levels and mental well-being.
Design/methodology/approach
The study follows a pre–post-test design. Mental health staff will be recruited for five weeks of VR relaxation. The authors will measure the feasibility and acceptability of the VR relaxation intervention as primary outcomes, alongside secondary outcomes evaluating the benefits of VR relaxation for mental well-being.
Findings
The study aims to recruit 20–25 health-care professionals working in both inpatient and specialist community mental health settings.
Originality/value
Research indicates the potential of VR relaxation as a low-intensity intervention to promote relaxation and reduce stress in the workplace. If VR relaxation is shown to be feasible and acceptable, when delivered across multiple sessions, there would be scope for large-scale work to investigate its effectiveness as an approach to enable health-care professionals to de-stress, relax and optimise their mental well-being. In turn, this may consequently reduce turnover and improve stress-related sick leave across health-care services.
