Public transportation usability for early voting in Ohio

Ohio, one of a handful of swing states in the 2012 Presidential election, has had its share of controversies over early voting. However, very little attention has been paid to how people can find out out where and when they can vote, and how best to get there.  This is especially sensitive for those who depend on public transportation, who arguably will have the hardest time making it to the polls.

Very layman use of situational awareness. Rant coming tomorrow.


Shared Goals in a Candidacy Exam

"The Candidacy Exam is dead ... long live the Candidacy Exam." This phrase has been floating through my brain since I took mine last week. Loosely translated, I think I want it to mean that the execution of the format of my candidacy left me thoroughly underwhelmed (I want it DEAD), but I absolutely want doctoral students to be able to attain and demonstrate a certain level of knowledge to indicate that they will be able to perform independently in the real world after their degree is attained (it must LIVE!).

Increase of control - loss of relevance?

In determining the strength of evidence, the accepted progression of study strength from low to high is: Editorials, Case Studies, Case-Control Studies, Cohort Studies, Randomized Controlled Trials, and finally Systematic Reviews.  Actually, I never even thought of Editorials before I found this snazzy pyramid.

Moderators and mediators

OK, this just fried my brain, but I think I have it straight now.  In creating a predictive model, two relationships can be seen if a direct relationship between the predictor (x) and the outcome (z) cannot be observed.  In the case of mediation, a quasi-causal relationship can be established between predictor and mediator variable, and a quasi-causal relationship can be established between the mediator and outcome variable.  This is depicted in Figure 1 on the right.

Design as mediator between science and business

Last week I talked to one of my favorite people. I brought up the notion of a designtist and she, true to form, has already:

The designtist - does such a beast even exist?

A dear friend and I started talking about building a site called "1000 bad ideas".  The idea is that a series of problems are thrown out to the community, and they are encouraged to submit designs that would solve it.  Any idea is fair game, and there is equal value in "good" and "bad" ideas.  The big idea is proliferation of ideas which will be pruned and combined, used for inspiration or tossed aside to ultimately create a solution. This is a macrocognitive version of my personal design process.

Twitter's contribution to Public Health

Very interesting article for how Johns Hopkins researcher mined Twitter for patterns.  You mean social media isn't just people talking about sandwiches?

Great post, Jakob!

I must confess that I am not a Jakob Nielsen accolyte, but I respect his work and, darn it, most of the  things he says are right on point (and the rest isn't far off!).  This one was a keeper to stoke my usability thinking ...

Parallel & Iterative Design + Competitive Testing = High Usability (Jakob Nielsen's Alertbox)

You can achieve a high-quality user interface by combining 3 design process models:

1. Competitive testing
2. Parallel design
