Abstract
INTRODUCTION Although physical activity (PA) reduces cardiovascular disease (CVD) risk, physical inactivity remains a pressing public health concern, especially among African American (AA) women in the USA. PA interventions focused on AA women living in resource-limited communities with scarce PA infrastructure are needed. Mobile health (mHealth) technology can increase access to PA interventions. We describe the development of a clinical protocol for a multilevel, community-based, mHealth PA intervention for AA women. METHODS AND ANALYSIS An mHealth intervention targeting AA women living in resource-limited Washington, DC communities was developed based on the socioecological framework for PA. Over 6 months, we will use a Sequential Multi-Assignment, Randomized Trial approach to compare the effects on PA of location-based remote messaging (named 'tailored-to-place') to standard remote messaging in an mHealth intervention. Participants will be randomised to a remote messaging intervention for 3 months, at which point the intervention strategy will adapt based on individuals' PA levels. Those who do not meet the PA goal will be rerandomised to more intensive treatment. Participants will be followed for another 3 months to determine the contribution of each mHealth intervention to PA level. This protocol will use novel statistical approaches to account for the adaptive strategy. Finally, effects of PA changes on CVD risk biomarkers will be characterised. ETHICS AND DISSEMINATION This protocol has been developed in partnership with a Washington, DC-area community advisory board to ensure feasibility and acceptability to community members. The National Institutes of Health Intramural IRB approved this research and the National Heart, Lung, and Blood Institute provided funding. Once published, results of this work will be disseminated to community members through presentations at community advisory board meetings and our quarterly newsletter. TRIAL REGISTRATION NUMBER NCT03288207.

Abstract
Thirty million Americans currently have diabetes, and a substantial portion do not reach the goals of clinical treatment. This is in part due to the complex barriers to effective self-care faced by people with diabetes. This study uses a patient work perspective, focusing on the everyday, lived experience of managing diabetes. Our primary research goal was to explore how the work of self-care is embedded in the other routines of everyday living. We found that everyday objects and spaces were instrumental in the incorporation of diabetes work into daily routines. Objects anchored diabetes tasks by linking illness-specific artifacts to space and time (e.g. a morning routine), and by enabling the performance on diabetes tasks while on the move in either planned or unplanned ways.

Abstract
In-vehicle driver distractions are an increasing cause of automobile accidents. Recent advances in wearable consumer technologies impose new challenges for managing driver attention and regulating device use in the driving context. Google Glass is a wearable interface that presents information via a heads-up display and read aloud function, neither of which obstructs the user’s view of the surrounding environment. While Glass may benefit drivers by providing driving-related notifications, no documentation exists objectively measuring the extent to which using Glass impacts driving performance and safety. This preliminary study compared texting with Google Glass to other texting methods in a driving simulation to examine driver behavior and performance. While texting-and-driving is inadvisable, the task of texting may be constructed so that it does not provide information that alters the intent of the driving task, reducing confounding factors in analysis of the device’s impact on driving performance. The results of this study suggest that Glass performs much clos-er to baseline than the other technologies. Evidence from this preliminary investigation was used to form a complete study evaluating texting-and-driving with Google Glass. Results from these studies can be used to inform developers of wearable technologies and policymakers tasked with regulating the use of these tech-nologies while driving.
