Your proposal "Real World Evidence" with the proposal ID "19562" has been approved for continuation in the 2019 EIT Health CAMPUS Portfolio! All Innovative Education proposals went through strict eligibility checks and intensive face-to-face evaluations with external experts. These steps were important in selecting outstanding proposals for our 2019 Business Plan. Your proposal has passed all stages of the selection process, something that you and your cross-EU team can feel proud of. As part of the final step in this process and before your project may officially join the 2019 BP we would like you to make some changes to your proposal. These changes are based on the feedback from Fall Review evaluation board. We have compiled a step-wise approach below. Please follow them accurately, in order, to ensure that your proposal is of top quality and can thus be approved by EIT to join the 2019 Business Plan.
Community-dwelling HIV/AIDS patients in rural Alabama self-monitored (SM) daily HIV risk behavior... more Community-dwelling HIV/AIDS patients in rural Alabama self-monitored (SM) daily HIV risk behaviors using an Interactive Voice Response (IVR) system, which may enhance reporting, reduce monitored behaviors, and extend the reach of care. Sexually active substance users (35 men, 19 women) engaged in IVR SM of sex, substance use, and surrounding contexts for 4–10 weeks. Baseline predictors of IVR utilization were assessed, and longitudinal IVR SM effects on risk behaviors were examined. Frequent (n = 22), infrequent (n = 22), and non-caller (n = 10) groups were analyzed. Non-callers had shorter durations of HIV medical care and lower safer sex self-efficacy and tended to be older heterosexuals. Among callers, frequent callers had lost less social support. Longitudinal logistic regression models indicated reductions in risky sex and drug use with IVR SM over time. IVR systems appear to have utility for risk assessment and reduction for rural populations living with HIV disease.

In humans and numerous avian species, dispersal from the natal family may not coincide with these developmental markers. This presents an adaptive puzzle, since delaying dispersal typically delays reproduction. Various ecological explanations for delayed dispersal in birds have been proposed and tested. Emlen (1995) suggested parallels between humans and birds with regard to the circumstances that influence family formation and dispersal timing. Work by other authors has applied Emlen's model to humans using proxy measures of "Natal Territory Quality" (NTQ). Using the Panel Study of Income Dynamics, a longitudinal survey of U.S. families, I extract direct measures of NTQ to more rigorously test Emlen's prediction that higher NTQ leads to later dispersal. I use two age-based cohorts (born in 1957 and 1967). Fo...

Despite their reach, there is a lack of knowledge about which methods are used for evaluating these courses. Objective The aim of this review was to identify current MOOC evaluation methods to inform future study designs. Methods We systematically searched the following databases for studies published from January 2008 to October 2018: (1) Scopus, (2) Education Resources Information Center, (3) IEEE (Institute of Electrical and Electronic Engineers) Xplore, (4) PubMed, (5) Web of Science, (6) British Education Index, and (7) Google Scholar search engine. Two reviewers independently screened the abstracts and titles of the studies. Published studies in the English language that evaluated MOOCs were included. The study design of the evaluations, the underlying motivation for the evaluation studies, data collection, and data analysis meth...

Nonetheless, leading universities continue to offer MOOCs, including many in the health sciences, on a number of private platforms. Therefore research on online education must include a thorough understanding of the role of MOOCs. Thus far studies on MOOC participants focus mainly on learners’ assessment of the course. We know that MOOCs are not reaching the universal audiences that were once predicted, and we know a lot about learners’ perceptions of MOOCs. However, there is little scholarship on what learners themselves gain from participating in MOOCs. OBJECTIVE As MOOC development persists and expands, scholars and developers should be aware of the role of MOOCs in education by looking at what they do offer their participants. In this qualitative synthes...
