Cross-Modal Health State Estimation

Individuals create and consume more diverse data about themselves today than any time in history. Sources of this data include wearable devices, images, social media, geospatial information and more. A tremendous opportunity rests within cross-modal data analysis that leverages existing domain knowledge methods to understand and guide human health. Especially in chronic diseases, current medical practice uses a combination of sparse hospital based biological metrics (blood tests, expensive imaging, etc.) to understand the evolving health status of an individual. Future health systems must integrate data created at the individual level to better understand health status perpetually, especially in a cybernetic framework. In this work we fuse multiple user created and open source data streams along with established biomedical domain knowledge to give two types of quantitative state estimates of cardiovascular health. First, we use wearable devices to calculate cardiorespiratory fitness (CRF), a known quantitative leading predictor of heart disease which is not routinely collected in clinical settings. Second, we estimate inherent genetic traits, living environmental risks, circadian rhythm, and biological metrics from a diverse dataset. Our experimental results on 24 subjects demonstrate how multi-modal data can provide personalized health insight. Understanding the dynamic nature of health status will pave the way for better health based recommendation engines, better clinical decision making and positive lifestyle changes.Comment: Accepted to ACM Multimedia 2018 Conference - Brave New Ideas, Seoul, Korea, ACM ISBN 978-1-4503-5665-7/18/1

Supporting Worth Mapping with Sentence Completion

Expectations for design and evaluation approaches are set by the development practices within which they are used. Worth Centred Development (WCD) seeks to both shape and fit such practices. We report a study that combined two WCD approaches. Sentence completion gathered credible quantitative data on user values, which were used to identify relevant values and aversions of two player groups for an online gambling site. These values provided human value elements for a complementary WCD approach of worth mapping. Initial worth maps were extended in three workshops, which focused on outcomes and user experiences that could be better addressed in the current product and associated marketing materials. We describe how worth maps were prepared for, and presented in, workshops, and how product owners and associated business roles evaluated the combination of WCD approaches. Based on our experiences, we offer practical advice on this combinination

Bidirectional relations of religious orientation and depressive symptoms in adolescents : a short-term longitudinal study.

Religious orientation can be divided into intrinsic and extrinsic: intrinsically oriented individuals “live their religion,” whereas extrinsically oriented individuals practice religion mainly to gain external benefits. In adults, depression has been found to correlate negatively with intrinsic religious orientation and positively with extrinsic orientation. Studies of the relation between religiosity and depression typically have not been longitudinal, conducted with adolescents, controlled for the influence of other factors associated with depression (i.e., negative cognitions), or examined the reverse relation of depression predicting religious orientation. Our four-month longitudinal study of 273 ninth-grade students addressed these issues. Results showed that higher intrinsic religious orientation measured at baseline significantly predicted lower self-reported depressive symptoms four months later, controlling for initial level of depressive symptoms and cognitive style; in contrast, extrinsic orientation and the interaction between religious orientation and life events did not significantly predict later depressive symptoms. Self-reported depressive symptoms, however, did not predict either intrinsic or extrinsic religious orientation four months later. Factors contributing to different findings for adolescents versus adults in the relation between extrinsic religious orientation and depression are suggested

Amplified ambivalence: having a sibling with juvenile idiopathic arthritis

Despite increased awareness of family responses to chronic illness and disability, there is still a need to understand experiences of well siblings. We begin to address this by asking “What is it like to have a sibling with juvenile idiopathic arthritis?” (JIA).Eight families with an adolescent diagnosed with JIA participated. Four members of each family, including one healthy sibling, were interviewed and transcripts analyzed using grounded theory. Analysis suggests healthy siblings see their family as different to ‘normal’ families, forfeit time with peers, share vicariously adverse experiences of their ill sibling, and feel inadequately informed. Such experiences amplify the ambivalent nature of sibling relationships and are possibly felt most strongly during late childhood and early adolescence. Support from extended family can reduce these negative experiences and facilitate social and emotional adjustment which also occurs over time as the children mature. These findings have implications for healthcare professionals and voluntary organizations

Evaluation of composting latrines

This paper presents the interim findings of a sanitation research project, undertaken in an urban informal settlement, with the support of the Greater Johannesburg Transitional Metropolitan Council (GJMC) and the Water Research Commission. A locally developed comporting latrine called the “Enviro Loo” is being evaluated in terms of health impacts and technical performance. Thirty comporting latrines were installed in the Elias Motswaledi settlement, south of Johannesburg, for trial use and monitoring over a period of one year. Results of the monitoring and the acceptability of these latrines as compared to a control group of thirty communal chemical latrine users, is discussed

Recognition without identification, erroneous familiarity, and déjà vu

Déjà vu is characterized by the recognition of a situation concurrent with the awareness that this recognition is inappropriate. Although forms of déjà vu resolve in favor of the inappropriate recognition and therefore have behavioral consequences, typical déjà vu experiences resolve in favor of the awareness that the sensation of recognition is inappropriate. The resultant lack of behavioral modification associated with typical déjà vu means that clinicians and experimenters rely heavily on self-report when observing the experience. In this review, we focus on recent déjà vu research. We consider issues facing neuropsychological, neuroscientific, and cognitive experimental frameworks attempting to explore and experimentally generate the experience. In doing this, we suggest the need for more experimentation and amore cautious interpretation of research findings, particularly as many techniques being used to explore déjà vu are in the early stages of development.PostprintPeer reviewe

Concealed concern: Fathers' experience of having a child with Juvenile Idiopathic Arthritis

Despite increased research into families of chronically ill children, more needs to be known about the father’s experience. We address this issue through asking: ‘What is it like to be the father of a child with juvenile idiopathic arthritis?’ (JIA). Four members of eight families with an adolescent diagnosed with JIA, including seven fathers, were interviewed and transcripts analyzed using grounded theory. This study suggests that fathers of children with JIA experience several severe losses which are exacerbated through comparisons they make between their own situation and that of fathers of healthy children. In addition, the fathers faced several constraints which reduced their opportunities to communicate with their ill child through shared activities. Fathers appeared to conceal their distress by adopting strategies of denial and distraction however their adjustment was facilitated, to some extent, by social support. They could also develop greater acceptance of their situation over time as the care of their ill child became assimilated into family life and constraints upon their life gradually reduced through the increased maturity of their son or daughter with JIA. These findings have implications for healthcare professionals and voluntary organizations
