Spherical clustering of users navigating 360{\deg} content

In Virtual Reality (VR) applications, understanding how users explore the omnidirectional content is important to optimize content creation, to develop user-centric services, or even to detect disorders in medical applications. Clustering users based on their common navigation patterns is a first direction to understand users behaviour. However, classical clustering techniques fail in identifying these common paths, since they are usually focused on minimizing a simple distance metric. In this paper, we argue that minimizing the distance metric does not necessarily guarantee to identify users that experience similar navigation path in the VR domain. Therefore, we propose a graph-based method to identify clusters of users who are attending the same portion of the spherical content over time. The proposed solution takes into account the spherical geometry of the content and aims at clustering users based on the actual overlap of displayed content among users. Our method is tested on real VR user navigation patterns. Results show that our solution leads to clusters in which at least 85% of the content displayed by one user is shared among the other users belonging to the same cluster.Comment: 5 pages, conference (Published in: ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

"A roller coaster of emotions": a qualitative study of parents very first experiences with their preterm baby

Objectives: To assess parents 19 first experiences of their very preterm babies and the neonatal intensive care unit (NICU). Design: Qualitative study using semistructured interviews. Participants: 32 mothers and 7 fathers of very preterm babies (<32 weeks gestation). Setting: Three neonatal units in tertiary care hospitals in South East England. Results: Five themes were identified. The first describes parents 19 blurred recall of the birth. The second shows the anticipation of seeing and touching their baby for the first time was characterised by contrasting emotions, with some parents feeling scared and others excited about the event. The third theme describes parents 19 first sight and touch of their babies and their 18rollercoaster 19 of emotions during this time. It also highlights the importance of touch to trigger and strengthen the parent 13baby bond. However, some parents were worried that touching or holding the baby might transmit infection or interfere with care. The fourth theme captures parents 19 impressions of NICU and how overwhelming this was particularly for parents who had not toured NICU beforehand or whose first sight of their baby was on NICU. The final theme captures unique experiences of fathers, in particular that many felt excluded and confused about their role. Conclusions: This study informs family-centred care by providing insight into the experiences of parents of very preterm infants at a time when they are most in need of support. Clinical implications include the importance of offering parents preparatory tours of the NICU and including fathers

Understanding the Implications of a Global Village

Whether the world is shrinking, expanding, or remaining the same metaphorical size, it is clear that how we communicate across physical and cultural boundaries is changing at an accelerated rate. With these changes comes a responsibility, as humans, to consider the implications of our shifting realities. Without an objective and inclusive analysis of these issues, we will be unprepared for the rollercoaster of cultural mayhem that could inevitably ensue. If we are in fact becoming a global village, we will be able to reach some sort of consensus as a global village about how these issues should be addressed in order to benefit all members of our village equally

Service users' experiences of a brief intervention service for children and adolescents : a service evaluation

Ten per cent of young people experience mental health difficulties at any one time. Prevention and early intervention leads to better prognosis for young people's mental well-being in the short and long term. Child and Adolescent Mental Health Services (CAMHS) must be able to provide swift and effective interventions for a range of difficulties to meet this need. This paper presents a service evaluation of the Brief Intervention Service in North Lincolnshire CAMHS. Nine young people and/or their families took part in semi-structured interviews that aimed to explore their experiences of receiving an intervention from the service. Template analysis was carried out to draw out themes from the interview transcripts. The three a priori themes were treatment outcomes, areas for potential improvement, and things that are working well; and an additional two emergent themes were emotional experience and managing practical barriers. In addition, all participants were asked about their satisfaction with the service and whether they would recommend the service to others. One hundred per cent reported feeling respected by their clinician when asked directly, and all felt that the service would be helpful for other young people and families. Overall, families were satisfied with the service and reported outcomes including improvements in symptomatology and family functioning. Specific recommendations as to how the service could be improved were made, which related to difficulties accessing the service, the content of the sessions, and communication within the service and with other services
