An Ode to the Benefits of Messy Environmental Policy

September 08, 2016

Ramiro Berardo and I recently published a new article on the structure of polycentric and complex governance systems for water management (sorry for the gated links…but see key figure inserted in this blog, where policy actors are circles, venues squares, and links represent participation).  We have been working on this project for a number of years, driven by the reality that most environmental governance arrangements involve many different actors participating in multiple policy venues, and working

useR! talk on teaching R

July 05, 2016

Here is a video recording of my talk from useR! 2016 on teaching R. It’s nominally about teaching a lot of students in an intensive format, but I think almost everything translates to traditional classes. If for whatever reason this video isn’t working out for you, here is the source.

This talk was just one in a great session. I’d highly recommend:

A Shiny app to help interpret GW-Degree estimates in ERGMs

June 26, 2016

Most researchers are misinterpreting geometrically weighted degree (GWD) estimates in exponential random graph models (ERGMs) of networks. By a 3:1 ratio papers cite positive estimates of GWD as indicative of a popularity or centralization force; in fact, positive estimates indicate dispersion of edges.

Participatory Learning Games for Social-Ecological Systems

March 17, 2016

How can a simple game represent a complex social-ecological system?  For the last few years, I have taught a graduate class on social-ecological systems (SES) that introduces SES concepts and frameworks along with delving into a number of related topics in environmental social science. A core activity of the class involves student groups choosing SES case studies, and applying the course topics from a particular week to the case study.

The Structure of Twitter Networks for California Agriculture

March 04, 2016

We just released a policy brief with our initial analysis of the structure of Twitter networks centered on California agriculture.  Starting with 153 users identified as relevant to California agriculture by the UC Division of Agriculture and Natural Resources, we traced the followers and followees of the initial group to identify approximately 59K Twitter users.  The results clearly support the idea that social media outlets like Twitter can be a valuable aspect of strategic
