Item Video see-through augmented reality fire safety training: A comparison with virtual reality and video training(Elsevier B.V., 2024-12-10) Domgue K LI; Paes D; Feng Z; Mander S; Datoussaid S; Descamps T; Rahouti A; Lovreglio RSafety training is crucial to mitigate the risk of damage when a disaster occurs and can play a vital role in enhancing community response. Augmented Reality (AR) is an emerging technology for safety training that holds great pedagogical potential. This study aims to explore the effectiveness of AR training in terms of knowledge acquisition and retention, as well as self-efficacy enhancement. We developed a new video see-through AR training tool on a tablet to teach users about operating a fire extinguisher to put out a fire following the PASS procedure: Pull, Aim, Squeeze, and Sweep (PASS). The AR training tool was tested with 60 participants. Test results were systematically compared with findings from the literature investigating Virtual Reality (VR) and video-based safety training. The findings indicate that, directly after the training, AR outperformed traditional video training in terms of knowledge retention, long-term self-efficacy, and quality of instructions. However, the AR experience was not as effective as the VR experience in all these areas, but the AR group had a smaller decrease in knowledge over time. These findings suggest that the AR-based training approach offers benefits in long-term memory recall.Item Advanced theory of mind and children's prosocial lie-telling in middle childhood: A training study(Elsevier Inc., 2024-10-01) Gao Q; Chen P; Huang Q; Wang ZChildren's advanced theory of mind (AToM) is concurrently associated with their prosocial lie-telling. However, the causal link between AToM and prosocial lie-telling has not yet been demonstrated. To address this gap, the current study adopted a training paradigm and investigated the role of AToM in children's prosocial lie-telling in middle childhood. A total of 66 9- and 10-year-old children who did not demonstrate any prosocial lie-telling in a disappointment gift paradigm at the baseline were recruited and randomly assigned to either the experimental group (n = 32) or an active control group (n = 34). The experimental group underwent a conversation-based training program of four sessions. The results showed significantly greater gains in AToM at the posttest for the experimental group children compared with the control group children, controlling for family socioeconomic status, children's literacy score, working memory, and inhibition. More important, the experimental group children were more likely to tell prosocial lies than the control group, even after controlling for the pretest AToM and other covariates. However, the training effects faded at the 6-month follow-up test after the training's completion. These findings provide the first evidence for the causal role of AToM in the development of prosocial lie-telling in middle childhood. The fade-out effect is discussed in the context of educational interventions.Item Prototyping and testing a virtual reality counterterrorism serious game for active shooting(Elsevier B.V., 2022-09-28) Lovreglio R; Daphney-Chloe N; Rahouti A; Paes D; Feng Z; Shipman AAn active shooting emergency requires an effective strategy to increase the chances of survival of the attacked population. Educational environments are one of the most common locations of such events. To reduce the impact of these disasters, several emergency plans have been developed and put in place. Traditionally, these emergency plans are taught to occupants using non-interactive videos, drills, etc. However, these conventional methods present many limitations regarding trainees' knowledge acquisition, engagement and self-efficacy. To overcome them, this paper presents the prototype of an immersive Virtual Reality (VR) Serious Game (SG) for counterterrorism training. A user-centred evaluation of the proposed training SG was conducted with 32 participants. The experiment aimed to investigate the impact of the proposed tool on participants' knowledge regarding the safest actions to take in case of an active shooter attack. Participants' intrinsic motivation and self-efficacy levels were also assessed before and after the VR-based training. Findings indicate that participants’ knowledge, intrinsic motivation, and self-efficacy significantly increased immediately after the training.Item Improving Performance of Autoencoder-Based Network Anomaly Detection on NSL-KDD Dataset(IEEE, 2021-09-29) Xu W; Jang-Jaccard J; Singh A; Wei Y; Sabrina F; Ji ZNetwork anomaly detection plays a crucial role as it provides an effective mechanism to block or stop cyberattacks. With the recent advancement of Artificial Intelligence (AI), there has been a number of Autoencoder (AE) based deep learning approaches for network anomaly detection to improve our posture towards network security. The performance of existing state-of-the-art AE models used for network anomaly detection varies without offering a holistic approach to understand the critical impacts of the core set of important performance indicators of AE models and the detection accuracy. In this study, we propose a novel 5-layer autoencoder (AE)-based model better suited for network anomaly detection tasks. Our proposal is based on the results we obtained through an extensive and rigorous investigation of several performance indicators involved in an AE model. In our proposed model, we use a new data pre-processing methodology that transforms and removes the most affected outliers from the input samples to reduce model bias caused by data imbalance across different data types in the feature set. Our proposed model utilizes the most effective reconstruction error function which plays an essential role for the model to decide whether a network traffic sample is normal or anomalous. These sets of innovative approaches and the optimal model architecture allow our model to be better equipped for feature learning and dimension reduction thus producing better detection accuracy as well as f1-score. We evaluated our proposed model on the NSL-KDD dataset which outperformed other similar methods by achieving the highest accuracy and f1-score at 90.61% and 92.26% respectively in detection.Item ANZAED eating disorder treatment principles and general clinical practice and training standards(BioMed Central Ltd, 2020-11-10) Heruc G; Hurst K; Casey A; Fleming K; Freeman J; Fursland A; Hart S; Jeffrey S; Knight R; Roberton M; Roberts M; Shelton B; Stiles G; Sutherland F; Thornton C; Wallis A; Wade TIntroduction Eating disorders are complex to manage, and there is limited guidance around the depth and breadth of knowledge, skills and experience required by treatment providers. The Australia & New Zealand Academy for Eating Disorders (ANZAED) convened an expert group of eating disorder researchers and clinicians to define the clinical practice and training standards recommended for mental health professionals and dietitians providing treatment for individuals with an eating disorder. General principles and clinical practice standards were first developed, after which separate mental health professional and dietitian standards were drafted and collated by the appropriate members of the expert group. The subsequent review process included four stages of consultation and document revision: (1) expert reviewers; (2) a face-to-face consultation workshop attended by approximately 100 health professionals working within the sector; (3) an extensive open access online consultation process; and (4) consultation with key professional and consumer/carer stakeholder organisations. Recommendations The resulting paper outlines and describes the following eight eating disorder treatment principles: (1) early intervention is essential; (2) co-ordination of services is fundamental to all service models; (3) services must be evidence-based; (4) involvement of significant others in service provision is highly desirable; (5) a personalised treatment approach is required for all patients; (6) education and/or psychoeducation is included in all interventions; (7) multidisciplinary care is required and (8) a skilled workforce is necessary. Seven general clinical practice standards are also discussed, including: (1) diagnosis and assessment; (2) the multidisciplinary care team; (3) a positive therapeutic alliance; (4) knowledge of evidence-based treatment; (5) knowledge of levels of care; (6) relapse prevention; and (7) professional responsibility. Conclusions These principles and standards provide guidance to professional training programs and service providers on the development of knowledge required as a foundation on which to build competent practice in the eating disorder field. Implementing these standards aims to bring treatment closer to best practice, and consequently improve treatment outcomes, reduce financial cost to patients and services and improve patient quality of life.Item Strength and Strength-Related Anthropometric Parameters of the International Level Canoe Slalom Male Paddlers(Sociedad Chilena de Anatomía, 2022-06-06) Busta J; Coufalová K; Cochrane DJThe aim of the study was to determine the differences in hand-grip strength and strength-related anthropometric parameters between the highest-performance international paddlers (HILP) and other international paddlers (ILP) in canoe slalom. In male competitors (n=48; 23 canoeists and 25 kayakers) who took part in the 2018 European championship event in canoe slalom in Prague, Czech Republic representing 15 European countries were measured hand-grip strength and strength-related anthropometric parameters two days prior the event. Differences between the group of HILP (medallists from Olympic Games, world championship and European championship in the previous three years and European championship finalists at the same time) and ILP were found. HILP have significantly higher forearm, arm and chest girths than ILP. Moderate or high practical differences and margin statistic differences were found also for hand-grip strength, body weight, body mass index and age. The consistently high-performing paddlers are heavier, have more muscular upper body and are stronger than the other group, while keeping their lower body lean. Therefore, regular upper-body strength training to all canoe slalom paddlers is important but caution is required because body weight over 80 kg may be a limiting factor. El objetivo del estudio fue determinar las diferencias en la fuerza de prensión manual y los parámetros antropométricos relacionados con la fuerza entre los remeros internacionales de alto rendimiento (RIAR) y otros remeros internacionales de canotaje en slalom. En hombres competidores (n=48; 23 piragüistas y 25 kayakistas) que participaron en el campeonato europeo de slalom en canoa de 2018, en Praga, República Checa, que representa a 15 países europeos, se midió la fuerza de agarre manual y los parámetros antropométricos relacionados con la fuerza dos días antes del evento. Se encontraron diferencias entre el grupo de RIAR (medallistas de Juegos Olímpicos, campeonatos del mundo y campeonatos de Europa en los tres años anteriores y finalistas del campeonato de Europa al mismo tiempo) y remeros internacionales. Los RIAR presentaban circunferencias de antebrazo, brazo y pecho significativamente más altas que los remeros internacionales. Además, se encontraron diferencias prácticas moderadas o altas y diferencias estadísticas en el límite para la fuerza de prensión manual, el peso corporal, el índice de masa corporal y la edad. Los remeros de alto rendimiento son más pesados, tienen la parte superior del cuerpo más musculosa y son más fuertes que el otro grupo, mientras mantienen la parte inferior del cuerpo esbelta. Por lo tanto, es importante el entrenamiento regular de fuerza de la parte superior del cuerpo para todos los remeros de piragüismo, sin embargo se requiere precaución debido a que el peso corporal superior a 80 kg puede ser un factor limitante.
