15 Minutes on Two-Stage Exams

I delivered a short presentation on two-stage exams1 at the Harvard Initiative for Teaching and Learning Annual Conference back in September. I’ve talked about these in the past, but this time (a) there’s more of a focus on quantifying collaboration, and (b) there are some neat visuals that I couldn’t show on a podcast. Video below.

  1. I’m increasingly calling these collaborative exams. We’ll see if that sticks.

Mac Power Users #319

This week I was on Mac Power Users to talk about my workflows related to teaching and academic research. I’m a huge fan of MPU so it was quite an honor to be on.

Have a listen – feedback always welcome.

How I will write my dissertation

In the spirit of getting my procrastinating done during the holidays (that’s how procrastinating works, right?), I thought I’d share how I choose to write complex papers. For my purposes, “complex” means any paper that involves some combination of:

  • citations linked to some bibliography manager;
  • equations;
  • internal links (a.k.a. “cross references”).

For simpler papers, I really do like Pages. It makes formatting relatively easy, it has (basic) EndNote and MathType support, and it looks lovely on high resolution displays. More recently, I’ve become smitten with Apple’s new Handoff feature that works with iOS 8 and OSX Yosemite devices. Being able to work on a paper at my desk, then pick up where I left off on my iPad as I move to the couch, then switch to my iPhone so I can stretch my legs, is pretty neat. Maybe this will get old someday, but for now it’s the bee’s knees.

Then there are the problems. In addition to the inability of Pages to satisfy my need for numbered equations, Apple is developing a bit of a reputation for poor backward-compatibility. I am terrified by the prospect of trying to open my dissertation in a few years and getting an alert like this (source: Google+):

This is totally unacceptable, and I hope Apple understands what a massive detterent this is.

The opposite end of the usability vs. flexibility spectrum, there’s LaTeX. LaTeX combines the longevity of plain text with a robust bibliography management system, not to mention the fact that LaTeX was conceived for the purpose of printing mathematical formulas. But, as the above links may suggest, LaTeX tools won’t be winning any awards for UI design.

Enter multimarkdown. Developed by Fletcher Penny, MMD allows me to use one of the hundreds of markdown[1] text editors for iOS using a syntax that can be exported as LaTeX. This export process does take some time to set up (see here for details), but once it’s read I simply have to prepend this metadata to the beginning of a file to make it export-ready:

Title: Title of my document
Author: Teddy Svoronos
latex input: /path/to/header/mmd-teddy-header
latex footer: /path/to/footer/mmd-teddy-footer
Base header level: 2
Bibtex: /path/to/bibtex/file/bibfull
Biblio Style:plain

I may get into the details of this setup in a later post; let me know if there’s any interest.

My editor of choice is Byword (which was recently updated to support Handoff), though I use Fletcher’s own MultiMarkdown Composer when I need to get in the weeds of internal links, table creation, and using the app’s native table of contents viewer.

The only potential rub in this setup is if my advisors want to use Word track changes to provide comments. In this case, I’ll have to export my file as rich text and do some manual futzing to make it presentable. Not great, but those occasional costs are outweighed by the benefits outlined above.

Boy, I’d better get writing.

Determinants of rural Liberians’ confidence in health care

I have a new paper out analyzing the results of a 2008 survey in Liberia, focusing on respondents’ confidence in their ability to obtain needed care. Though this particular paper has no relation to recent troubling events in Liberia, the issue of health system confidence is surely playing a role in the progression of events today.


Background: Following a protracted civil war, Liberia is rebuilding its health system.  One of the aims of reconstruction is to expand access to health care to a previously underserved rural population.

Objective: This study analyzed the determinants of Liberians’ confidence in their ability to obtain needed care for themselves or their children in case of serious illness.

Methods: A cross-sectional survey of 1,435 adults in Nimba County, Liberia was conducted. Logistic regression models were estimated with reported ability to obtain needed health services for serious illness as the dependent variable, and demographics, health need, health system characteristics, and informal health care as independent variables.

Results: Overall, 50.56% of respondents reported that they could obtain needed services for themselves or their children.  Confidence in the ability to obtain care increased with education (odds ratio (OR) 1.62, 95% confidence interval (CI): 1.19 – 2.21) and poor physical health in the past 30 days (OR 1.38, 95% CI: 1.01 – 1.88), and decreased with poverty (OR 0.66, 95% CI: 0.47 – 0.93), exposure to previous trauma (OR 0.50, 95% CI: 0.36 – 0.71), dissatisfaction with respondents’ last formal health visit (OR 0.70, 95% CI: 0.54 – 0.91), and high utilization of the informal health sector (OR 0.84, 95% CI: 0.73 – 0.96). No correlation was found between health system confidence and being female, being 35 years old or younger, formal health sector use, being within an hour of a clinic and the closest clinic having basic capabilities.

Conclusions: Respondents’ experiences with the health care system had a greater correlation with their confidence in obtaining needed health care than proximity or quality of medical equipment in health clinics.  Despite pro-poor policies guiding health system reconstruction, poor and less educated individuals have less confidence that the health system can meet their health needs.
