In this paper we present the rationale and beginning of work on improving e-Iearning objects through the use of analytics modeled after Google Analytics. Prior work on the use of metrics in e-Iearning has focused on user satisfaction, and the ranking and selection of learning objects from a set of available choices. This work differs in its focus on the kinds of metrics needed to improve an existing object, or even more specifically to make improvements to specific pages within an object. This work is based on the now well established track record of using Google Analytics for website optimization in e commerce. We discuss adaptations needed to apply similar metrics in the context of e-Iearning and more specifically e learning objects.
This chapter surveys the context for web services security and discusses the issues and standards at every level of architectural. The authors attempt to evaluate the status of industrial practice with respect to the security of web services. They look at commercial products and their supporting levels, and end with some conclusions. They see a problem in the proliferation of overlapping and possibly incompatible standards. Reliability is also an important aspect. They discuss some of its issues and consider its effect on security. A basic principle of security is the need to secure all levels of architecture; any weak levels will permit attackers to penetrate the system. These levels include: Business workflow level, catalog and description of web services level, communications level (typically SOAP), and storage of XML documents. There is a variety of standards for web services security and reliability and the authors will look at most of them.
An underlying theory is a framework of goals, solutions, and assumptions that guide how we observe situations and define problems. In science, the underlying theories, like particles, waves, relativity, plate tectonics, and evolution, are well known and well understood. In process improvement, the underlying theories are not so well understood. To address that problem, we present a system of patterns. The system includes six patterns for theories that underlie many of the well known practices in process improvement. The patterns are Plan, Best Practices, Flow, Feedback, Systems Thinking, and Living System. These patterns are found in ISO 9000, PMBOK, CMMI, SPICE, Lean, TQM, Six Sigma, and Agile. Like all patterns, the patterns in this system are structural configurations that solve a problem in a context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
