Propensity scores: An introduction and experimental test

Article Abstract:

A general introduction to propensity score analysis is presented by using data from a quasi-experiment as compared to a bench-mark randomized one, advice as to the method of analysis, limitations of the approach, and the use of classification tree analysis and bagging for classification trees in the construction of propensity scores. More extensive study in both stimulated and real data is suggested and caution advised on relying on the technique routinely due to its unpredictability.

An introduction to Luhmann

Article Abstract:

The social theories of Niklas Luhmann are skeptical about modernist rationality and express strong reservations about the possibilities of communication and solutions to social problems. Luhmann sees society as a series of communicative sub-systems such as politics, law, and science, but feels very little information generated by each system can be shared with another system. This line of reasoning suggests the interventionist strategies of politics have little chance of success.
