Presentations

Anderson, Emily E. (2016, June 21). Revisions to the Common Rule: What to Expect and How to Prepare [PDF of PowerPoint slides]. Institute for Health Research and Policy, University of Illinois at Chicago.

Emily E. Anderson, PhD, MPH, of Loyola University reviewed the Notice of Proposed Rulemaking for Revisions to the Common Rule (NPRM) that was issued by the Office of Human Research Protections in September 2015. She discussed the rulemaking timeline, the substance of proposed changes, and the presenter’s critique of proposed changes.

Review the slides from Dr. Anderson's presentation.

Pugach, Oksana. (2016, Feb. 9). What You Need to Know about Power Analysis through Simulation. Institute for Health Research and Policy, University of Illinois at Chicago.

In some settings analytic power calculations may not be readily available. Moreover, in situations of complex study design such as longitudinal cluster-randomized clinical trials with non-continuous outcomes, there are no analytic formulae that would adequately capture data specifics. A straightforward alternative is to estimate power empirically via Monte Carlo simulation. In this Chalk Talk, Dr. Pugach discussed the effect on power of changing various simulation conditions controlled by the researcher.

Kim, Yoonsang. (2015, Nov. 10) Statistical Getting Started with Probabilistic Topic Models [PDF of PowerPoint slides]. Institute for Health Research and Policy, University of Illinois at Chicago.

A topic model is an unsupervised machine learning technique. Probabilistic topic modeling is used to discover the themes in a large unstructured collection of documents by analyzing the words in documents. The talk focused on the simple topic model, latent Dirichlet allocation.

Reinforcement Pathology of Obesity

Epstein, Leonard H. (2015, Nov. 5) Lead Foot and Worn Brakes: Reinforcement Pathology of Obesity [PDF of PowerPoint slides]. Institute for Health Research and Policy, University of Illinois at Chicago.

Obesity is characterized by a strong motivation to eat and difficulties in delaying gratification. Reinforcement pathology is a theoretical approach combining food reinforcement and delay discounting to better understand the origins of obesity and new treatment opportunities. The interaction of these two factors in obesity will be discussed, as well as new treatment approaches to reduce food reinforcement and improve the ability to delay... more

What Works and What Doesn't

Fitzgibbon, Marian. (2015, March 18) Obesity Interventions in Underserved Populations: What Works and What Doesn't [PDF of PowerPoint slides]. Institute for Health Research and Policy, University of Illinois at Chicago.

This talk by Dr. Marian Fitzgibbon focused on lessons learned from obesity prevention and treatment interventions with minority and underserved populations.
