Three approaches to qualitative content analysis.
, 2005
"... Content analysis is a widely used qualitative Researchers regard content analysis as a flexible method for analyzing text data The differentiation of content analysis is usually limited to classifying it as primarily a qualitative versus quantitative research method. A more thorough analysis of th ..."

of approaches categorized as qualitative content analysis. We have identified three distinct approaches: conventional, directed, and summative. All three approaches are used to interpret text data from a predominately naturalistic paradigm. We begin with a brief review of the history and definitions of content

Why Johnny can’t encrypt: A usability evaluation of PGP 5.0
, 1999
"... User errors cause or contribute to most computer security failures, yet user interfaces for security still tend to be clumsy, confusing, or near-nonexistent. Is this simply due to a failure to apply standard user interface design techniques to security? We argue that, on the contrary, effective secu ..."

standards: PGP 5.0. Our case study used a cognitive walkthrough analysis together with a laboratory user test to evaluate whether PGP 5.0 can be successfully used by cryptography novices to achieve effective electronic mail security. The analysis found a number of user interface design flaws that may
A survey of industrial model predictive control technology
