Population and the Environment: Analytical Demography and Applied Population Ethics/KaitlynDavis

From Complex Time

Notes by user Kaitlyn Davis (UC Boulder) for Population and the Environment: Analytical Demography and Applied Population Ethics

Post-meeting Reflection

1+ paragraphs on any combination of the following:

  • Presentation highlights
  • Open questions that came up
  • How your perspective changed
  • Impact on your own work
  • e.g. the discussion on [A] that we are having reminds me of [B] conference/[C] initiative/[D] funding call-for-proposal/[E] research group

Most useful thing learned in course:

For me, the most useful about this course was seeing more examples of and talking through the process of moving from 1) establishing research questions to 2) identifying the key variables to 3) developing the equations to relate the variables to each other to 4) developing models of how the systems work. For me, steps 3 and 4 have always been the most difficult and are currently the steps I am thinking through for my dissertation. Getting to talk with other researchers about this process and seeing how they developed equations and models to capture and depict their topics of interest has helped me make some inroads to get started on this process in my own research.

Some additional useful things learned in the course:

-The importance of always being aware of and periodically re-assessing/re-identifying the interplay between 1) models/abstractions of data patterns and 2) on the ground interviews and data collection that reveal the key variables/driving factors and logics/frameworks of the subjects that contribute to the observed data patterns (such as in Caroline Bledsoe’s . Without this ground-truthing and finding out what variables actually matter for the study organisms and how they conceptualize them, our models will be flawed due to either missing key variables or not being able to actually explain the implications of the patterns they show.

-The importance of considering time lengths/durations in a process. For example, as we saw in Mary Shenk’s lecture on demographic transitions, the same pattern (e.g. declining fertility rate), but over different time scales (e.g. a longer time in one area than another), can have significantly different impacts (e.g. amount of population in each of the two different areas). Another example from this workshop was thinking about what is the temporal resolution of our data and how this aligns with the temporal resolution of the variable of interest (such as Lori Hunter discussed in terms of census data and temporary migrations).

-What models to use for particular demographic problems (and how to accommodate variation and additional parameters)

Applications for my dissertation research:

As I’m building models and thinking of variables to consider for my dissertation, which deals with agricultural adaptations in light of socioeconomic changes in the indigenous American Southwest, this workshop will be extremely helpful (particularly Chris Kempes’s work on the land/resources needed to sustain a given population and Charlotte Lee’s model integrating environment, population, and society).

Reference material notes

Some examples:

  • Here is [A] database on [B] that I pull data from to do [C] analysis that might be of interest to this group (insert link).
  • Here is a free tool for calculating [ABC] (insert link)
  • This painting/sculpture/forms of artwork is emblematic to our discussion on [X]!
  • Schwartz et al. 2017 offers a review on [ABC] migration as relate to climatic factors (add the reference as well).
