Flow theory has been borrowed from psychology to address positive user experiences with personal computers, and more recently, the Internet. The flow experience has been correlated to increased exploratory behavior, communication, learning, positive affect, and computer use. This paper reviews the flow studies within computer-mediated environments to gain a more coherent understanding. The auth...

This article reports on a workshop held to explore the potential uses of operational earthquake forecasting (OEF). We discuss the current status of OEF in the United States and elsewhere, the types of products that could be generated, the various potential users and uses of OEF, and the need for carefully crafted communication protocols. Although operationalization challenges remain, there was ...

For analyzing argumentative text, we propose to study the ‘depth’ of argumentation as one important component, which we distinguish from argument quality. In a pilot study with German newspaper commentary texts, we asked students to rate the degree of argumentativeness, and then looked for correlations with features of the annotated argumentation structure and the rhetorical structure (in terms...

Method Fourteen federally qualified community health centers (FQHCs) in Seattle and King County, Washington participated (2008-2015) in an effort to implement collaborative care for depression in high risk mothers. An expert panel based framework was used to identify key elements of the collaborative care model. This theory based framework guided operationalization of fidelity measures of this ...

Frailty represents a growing challenge to modern health-care systems. This paper reports on a conference on frailty held in Athens in January 2012. Papers from 11 groups, including those of the authors, were presented and discussed over two days. Several approaches to frailty and its operationalization (including biomarkers) and to social vulnerability were discussed. The search programs that i...

Intelligent systems and their applications are proliferating. Embedded Intelligent Real-Time Systems (EIRTS) are one type of intelligent system. Defining and measuring the complexity of this kind of system may help with better design, development, maintenance, and performance of EIRTS. In this paper, we propose a set of evaluation criteria to measure the complexity of Embedded Intelligent Real-...
