It’s that time of year again…

Published under Academia, Humor, Off Topic, Wikipedia

New undergrads on campus. Which means I get to hear all sorts of silly thing like:

Wombats are just like little kangaroos, right?

According to Le’ Wikipedia, they are both of the order Diprotodontia, and they both live on the Australian continent, but that’s as close as they get. Like comparing a fox and a polar bear because they’re both in the order Carnivora.

In other news, I’m looking for someone to help fix/update the blog software. He or she would be paid a modest fee. Leave your email in the comments and I’ll get back to you.

Time, Timely Content, and Timely Spam

Published under Academia, Off Topic, Wikipedia

One commenter on my post last Friday suggested that I may not have been too busy to be writing a blog. I have been editing at Wikipedia, but that’s just plain fun. Not the writing part, but watching people get worked up over minor things. And trying to figure out the Wiki-way, even though it’s clear the Wiki-way doesn’t work for somethings. Fun all around.

Anyway, the main reason I haven’t been blogging is because I’ve been trying to lose weight. Sometime last year I tipped the scales at almost 200 pounds {{convert|200|lbs|kg}} at 6 feet {{covert|6|ft|m}} tall (too bad those WP templates don’t work on this blog). Just your typical lazy, fat American. Or simply American to non-Americans. This morning, I was 160 lbs. Woot. And without a gym membership too. My routine consists of running, push ups, sit ups, and pull ups. Notice that they’re all free… because I’m a cheap bastard.

And speaking of timely, I just got this email.

Dear Professor [redacted]

Short summer sessions and the economy both point toward the use of custom course materials as opposed to textbooks…

Darned spammers got my title wrong (not that I’m complaining a whole lot though), but I am teaching 2 intro classes this semester and haven’t decided on a textbook yet. Maybe I’ll try them out…

Peer Review for Blogs

Published under Academia

This is a review of a blog post by Amardeep Singh blogged about Idea for Discussion: An Academic Blog Review.

In theory, like others, I think the idea of a peer reviewed system for blogs is a good idea. Peer review has several advantages over the status quo; it offers authors feedback on posts they have written, it offers guildance to readers on where to find good posts, and blogs would possibly be able to be used in academic pursuits.

Blogs already have a feedback mechanism for authors. It’s called comments, and to a lesser extent trackbacks. However, these comments are almost always made anonymously or pseudo-anonymously such that nobody knows who actually wrote them. I always sign all my comments as N. Johnson with a link to my blog. It’s not hard to figure out who I am, I just like making people look a little for it. When the author of a comment is not know, his or her expertise can not be accurately judged. But when the identity of a reviewer is known, they sometimes are not as truthful if they think the article is not as good as it should be, perhaps fearing retaliation. I believe any peer reviewed for blogs would need to be an anonymous system such that the reviewers were previously vetted and were found to be experts in their field.

However, as Cognitive Daily: Peer review for blogs points out, the current academic peer review system doesn’t work all that great. It’s hard to get academics to review papers. Not because they don’t think it’s important, but because it requires a large amount of time which could be spent on other things, such as their own research. He quotes Singh’s answer to this problem.

My idea is to have a system of academic blog reviewing, where people self-select individual blog posts they’ve written for review by others, perhaps using a combination of Technorati tags and emailed links. The reviewers could consist of fellow bloggers (credentials no bar) as well as non-blogging academics in a given discipline, who would publish their reviews on a central site. The reviewers could choose to be “onymous” or pseudonymous (as long as it is a consistent pseudonym, and contact information is available to site admins), and be asked to write a significant evaluation to the post in question (say, 250 words). Other reviewers and readers of the reviews could also evaluate the reviewers’ comments, as a way of maintaining standards for reviewers. Troll-like, unfair reviews would be deleted, and their authors denied reviewing privileges.

As I said above, I don’t think having reviews open to everyone is a good idea. We already have that in comments. Reviews must be done by someone knowledgable about the topic. For instance, I would feel vastly unqualified to comment on blog posts at Cognitive Daily, but I may feel qualified (depending on the specific subtopic) to comment on posts at Fermi Paradox. Some people naturally only comment where they know they know they have enough specific knowledge to add something to the discussion, others just like to comment to comment. So besides that issue with his proposal, I think it sounds good; we need a way to evaluate posts and even entire blogs. I hope someone soon implements a system of peer reviews for blogs and it gets used.

Research Update and General Grumblings

Published under Academia

As I’ve written about before, I’m using principle components analysis (PDF) in an attempt to distinguish two processes that occur in stratocumulus clouds. The problem - or so I’ve been told - is that PCA will separate covariance into orthogonal basis vectors regardless if there are two processes or not. Therefore, when attempting to interprete, it’s important to make sure that the results tell you exactly what you think they tell you. In my case, it’s fairly easy to do: I just look at a different day. Happily, when I did, I got the same results as before… kinda… but I cheated. Okay, cheated isn’t the right word. But when I looked at day x+1, the results were slightly different than day x. Argh. When I looked at day x+2 though, I was in heaven. Exactly the same as day x. I rushed to find the advisor, but he had already left for the weekend - and who could blame him, it was 7:30pm. I decided since he was gone, that was a good excuse for me to leave too, though I probably should have stayed and looked at some other stuff. Add to that that I’m terribly unproductive on Monday mornings. Is anyone productive on Monday morning? Maybe the weekend should be extended until noon on Monday. I’d gladly give up Friday nights so I didn’t have to come into work on Monday.
