ECAR Students and IT Study: CMS Chapter. http://www.educause.edu/ir/library/pdf/ers0506/
rs/ers05065.pdf
It would be easy to make too much of this chapter from a recent ECAR report on Students and Information Technology, 2005: Convenience, Connection, Control, and Learning, as it seems to paint an overall positive picture of student experiences with CMS. In the highlights it states that of students who report having used a CMS in one of their courses, 75% reported a positive or very positive experience.
A deeper look reveals, however, that the respondents were reflecting overwhemingly on an experience of using a CMS in a blended or mostly f2f situation, and that much of what was viewed as positive was focused on CMS' ability to facilitate somewhat administrative tasks, like accessing syllabi, course notes and grades. - SWL [EdTechPost]

The many meanings of metadata.
As we weave more and better metadata into software, documents, Web sites, and file systems, the information stored in these various containers will become more available, more cohesive, and therefore more useful. The next challenge is how -- in this new era of interconnected systems, people, and business processes -- to unite these separate realms.
The solution is a complex recipe, but we can find many of the ingredients at work in the emerging discipline of SOA (service-oriented architecture). We use metadata to describe the interfaces to services and to define the policies that govern them. The messages exchanged among services carry metadata that interacts with those policies to enable dynamic behavior and that defines the contexts in which business transactions occur. The documents that are contained in those messages and that represent those transactions will themselves also be described by metadata.
There's no overarching schema for the metadata that flows through the service network, touching routers, registries, security gateways, databases, and end-user applications. And, in view of its many forms and uses, it's not clear that convergence on a single standard is necessary or even desirable. What is necessary is that within each metadata domain we strike healthy balances between the constraints we apply to metadata vocabularies and the evolutionary freedom we allow them. Across domains, we'll speak the lingua franca of data and metadata, namely XML. [Full story at InfoWorld.com]

Hormone can reduce food intake, body weight. Research has demonstrated that a hormone found naturally in the body has the ability to cause limited weight loss. Specifically, the research revealed that peptide YY (PYY) can reduce food consumption in the morning, leading to a mild level of weight loss in the short term. The research is printed in the current edition of the journal Diabetes. [Science Blog -]
