Hi. I didn't post a follow-up over the weekend.
I did indeed finish up the proposal, and I turned it into the committee. It ain't perfect, but it's done...for now. As I delivered a hard copy to the home of one committee member, I reminded him that I'm a musician by trade. I said, "Just keep in mind: the first time an orchestra plays together, it usually doesn't sound all that good. This proposal may be similar." He graciously said, "Oh c'mon, it'll be fine, Rob," so perhaps that's a good sign that they're not seeking perfection, just completion. We shall see.
Meanwhile, I started my "snowball sampling procedure." This means I've asked about 14 faculty and staff members that I know here at LMU about helping me recruit people eligible to participate in my interviews. I've asked them things like, "Do you know of students who fit these criteria?" and "Feel free to pass this along to others." The hope is that the snowball, or the sample of participants, gets larger and larger the farther it rolls, or in this case the more it's shared. I'm seeking about 8-15 people total, and already I have contact information for 10! Amazing how fast this occurs after getting over the proposal-writing hurdle.
