I’ve been grading the last batch of papers and final exams for my online students this week. Some of my blog posts are shorter than usual, but I have been posting some long articles that I had finished a few weeks ago.

I’ll return to my usual long posts next week.

Grading has been a challenge because one part of the TurnitIn.com grading system is not working properly. One reason that I like TurnItIn.com is its online paper marking system, GradeMark. The commenting portion of the system is working just fine.

Usually I check off my scoring marks in a very pretty graphical matrix, which then calculates the assignment grade based upon the total number of possible points for the criterion (row) multiplied by a percentage on a vertical scale (column).

I have to create that matrix in a web-based editor, and it’s the matrix editor that is crashing. The matrix files are stored as a complex text file, and I have not figured out a way to create that file myself. Here’s an example of a rubric file.

So I have reverted to my old stand-by system: typing the scoring matrix into the general comments section of each paper’s GradeMark report.

Then I calculate the grade myself and enter that number into the TurnItIn.com gradebook.

This takes a bit longer than the automated system, but I rigged up a macro that types in a basic grading matrix for me.

Google is teaming up with Clearwire, Sprint, Time Warner Cable, Comcast and Intel to build a national WiMAX network. See the New York Times, the Washington Post, and Branding Post for more details.

The new joint venture will retain the Clearwire brand name and Clearwire’s existing consumer WiMAX business. Sprint contributes its network infrastructure and 2.5 gHz frequency allocation. It’s possible this deal will clear the FCC and antitrust regulators, because Google isn’t a major owner in the JV.

Yesterday, a Wall Street journal blog referenced my billso.com article of 18 April 2008 in a discussion about Yahoo and Google’s possible cross-licensing deal. The Clearwire deal is a more direct combination that may help the JV partners lock in consumers, businesses and advertisers.

Too many partners?

I’m reluctant to believe if this large joint venture can actually work. Sprint is the lead partner with a 51 percent stake, and this seems like a desperation move to being acquired outright by Deutsche Telekom or another company.

Pricing and marketing may determine if consumers will pay any attention to this JV. Can Clearwire and Sprint can offer their existing customers some compelling reasons to get some new hardware and try WiMAX? Verizon earns 23 percent of its wireless revenue from data calls on that company’s EVDO and other networks.

Google does need a vast network in the US to support its Android smartphone platform, and the company can’t wait or afford to build it from scratch.

WiMAX would give Google an alternate medium for data service, instead of relying on one telecom carrier as Apple has done with AT&T. Even with 3G service, the iPhone’s data transfer rates will seem slow when the user can’t get WiFi access.

Yes, the iPhone does support WiFi. But I’m sure Clearwire and its partners will market Android phones that support WiFi as well as WiMAX and the sponsoring carrier’s cell phone service, but the battery drain for a typical mobile device user may be a serious problem.

IDG, the publisher of InfoWorld, ComputerWorld, MacWorld and other technology magazines has been shifting away from paper to online editions. This New York Times article mentions that the transition has generated more revenue than the company expected:

Today, I.D.G. says, the InfoWorld Web site is generating ad revenue of $1.6 million a month with operating profit margins of 37 percent. A year earlier, when it had both print and online versions, InfoWorld had a slight operating loss on monthly revenue of $1.5 million.

This is remarkable given that some IDG titles like CIO magazine are distributed free of free of charge. Advertisers subsidize the content for both the web-based and print editions. While some IDG titles like InfoWorld are online only, CIO is still available in a twice-monthly print edition, largely because advertisers believe the target audience is less likely to read the online version. CIO also features longer articles than InfoWorld these days.

IDG has also added multiple RSS feeds to its web sites, to capture readers who prefer to use feed aggregators.

Many of these IDG magazines have been cited in previous billso.com articles, such as this post from 7 May 2008. I also list some of these titles on my references page, which contains many reliable and authoritative sources for researchers, managers and my students.
