Disciplinary bridges ... how's your sense of direction?

As an advocate for Hodges' model, I've acquired an affinity for inter- multi- transdisciplinary bridges, especially medical sociology, those leading towards the mathematical, and human geography. An old but significant influence is:

Chapman, K. (1979). People, pattern, and process: an introduction to human geography. London: Edward Arnold.

Chapman begins with the concept of distance, speed of movement and the consequence of the shrinking world. Our ability to move faster has radically altered the total travel time: from what was a 50 mile walking-day. In chapter 2, 'A Conceptual Framework' refers to:

• Decision making - the basic mechanism
• The Spatial Context
• The Content of Space
• Dimensions of Space
• Spatial Process - Causality in Time and Space

Overall, the book also takes me back to a paper I cited in 2007: Bell jars and bell curves

I'm sure the 'School of Geography' at Leeds is unrecognisable today from that of the 1980s. But the referenced paper in the 'Bell jars..' post:

Macgill, S.M. (1984). Structural Analysis of Social Data, A Guide to Ho's Galois Lattice Approach and A Partial Re-Specification of QAnalysis, Working Paper 416, School of Geography, University of Leeds. Abstract 1985

- still gives me an itch I can't scratch. 

 I could not fully understand, or follow, the print quality doesn't help, but it captured my imagination (perhaps that is enough?).

Chapter 9 stands out with 'Spatial Pattern' pp.203-234, 9.1.1 Topologic Structures, pp.205-209. Here, Chapman explains and has examples of connectivity matrices, with three indices to calculate the connectivity in a graph. All grist for the mill.

Happy Solstice too!
