PIOTRe: Personal Internet of Things Repository

Resource-constrained Internet of Things (IoT) devices like Raspberry Pis', with specific performance optimisation, can serve as interoperable personal Linked Data repositories for IoT applications. In this demo paper we describe PIOTRe, a personal datastore that utilises our sparql2sql query translation technology on Pis' to process, store and publish IoT time-series historical data and streams. We demonstrate with PIOTRe in a smart home scenario: a real-time dashboard that utilises RDF stream processing, a set of descriptive analytics visualisations on historical data, a framework for registering stream queries within a local network and a means of sharing metadata globally with HyperCat and Web Observatories

Interoperable & efficient: linked data for the internet of things

Two requirements to utilise the large source of time-series sensor data from the Internet of Things are interoperability and efficient access. We present a Linked Data solution that increases interoperability through the use and referencing of common identifiers and ontologies for integration. From our study of the shape of Internet of Things data, we show how we can improve access within the resource constraints of Lightweight Computers, compact machines deployed in close proximity to sensors, by storing time-series data succinctly as rows and producing Linked Data ‘just-in-time’. We examine our approach within two scenarios: a distributed meteorological analytics system and a smart home hub. We show with established benchmarks that in comparison to storing the data in a traditional Linked Data store, our approach provides gains in both storage efficiency and query performance from over 3 times to over three orders of magnitude on Lightweight Computers. Finally, we reflect how pushing computing to edge networks with our infrastructure can affect privacy, data ownership and data locality

Sexual Minority Stress, Resilience, and Intimate Relationships: An Examination of Individuals with Commitment Uncertainty

University of Minnesota Ph.D. dissertation. August 2019. Major: Family Social Science. Advisor: Steven Harris. 1 computer file (PDF); viii, 117 pages.Minority stress has been shown to negatively impact the mental health of sexual minorities and decreases same-sex relationship well-being. This dissertation examined the impact of minority stress on the mental and relational health of sexual minority individuals in same-sex relationships at the individual and couple level. The sample consisted of 280 participants, all of whom indicated they were currently in committed same-sex relationships and had seriously considered terminating their relationship at some point in the last six months. Data were analyzed using structural equation modeling with latent mediation and moderation. The first results of the first analysis showed that family rejection and nondisclosure were associated with increased uncertainty regarding one’s commitment to their relationship. Family rejection increased nondisclosure and decreased redemptive framing. Redemptive framing fully mediated the relationship between family rejection and uncertainty. Results of the second analysis indicated that social recognition can increase negative mental health symptoms through an increase in perceived constraint on the relationship. LGBT community connectedness moderated the relationship between social recognition and perceived constraint. At low levels of connection, recognition had some effect on constraint while high levels of connection resulted in a more substantial increase in constraint due to recognition. Clinical implications and future directions are discussed

Viewing the Learning Process: Assessment Via Usability Testing

Learning through Computer-Based Activities Provides a Multi-Modal Approach in Which the User Can Select the Educational Media and Process. Effective Development of These Activities Requires an Understanding of User Interactivity. Traditional Assessment, Such as Test Scores and Subjective Surveys, Looks at End Results and Attitudes. This Method Does Not Monitor the Learning Process. in Particular Developer Needs to Accommodate Diverse Usage Preferences and Choices. Hence, Assessment Should Involve Usability Measures that Are Quantitative and Qualitative. Usability Testing Records Usage Patterns and User Reactions. a Usability Laboratory Was Created at the University of Missouri-Rolla. It is Supplements the Traditional Assessment for Hypermedia Tutorials and Virtual Laboratories. the Laboratory is Designed to Provide Information on User Choices and Comfort. the Test Setup Provides (1) a Time Record and Progression of Intermediate Steps and (2) Visual and Auditory Clues to Subjective Factors. the Quantitative Measures Indicate How Efficiently and Accurately a User Comprehends and Navigates. the Qualitative Measures Indicate Satisfaction and Frustration during the Learning Process. an Example Test of a Prototype Virtual Laboratory is Described
