J. Craig Jenkins and Charles Perrow, "Insurgency of the Powerless: Farm Worker Movements (1946-1972)"

Chapter 4 (37-51) in McAdam & Snow.

American Sociological Review, April 1977, 42: 249-268.

On JSTOR:

This article is sometimes cited as an early exemplar of the dominant resource mobilization "school" of social movements. Since their focus is clearly on resources that are external to protest participants, we would classify their theory as a political opportunity theory.

Jenkins and Perrow begin by contrasting the "classical" model with their new perspective. The classical model they describe is what we have called the discontent theory of social movements. It is not very different from what most of us think of as a common sense theory of social movements. So the article is important for alerting us that our common sense may be wrong.

Two models of social movements

Three contrasts between the classical/common sense model and the resource mobilization perspective that you must understand are:

Changes between 1940s and 1960s

List at least three obstacles that the farm worker unions faced in organizing a union. What obstacles became less of a problem between the 1940s and the 1960s? How did the farm worker union movement itself change during that period? For Jenkins and Perrow, among all these changes, what was the one crucial change that spelled the difference between the two periods?

Methods

What is Jenkins and Perrow's data source? Compare this to earlier readings such as Tarrow's article on protest cycles and McAdam's article on innovation in the civil rights movement.

What problems do Jenkins and Perrow acknowledge with this data source and how do they defend their choice?

Results

The first period

What is the meaning of the correlation coefficients that Jenkins and Perrow calculate? For example, what does it mean in Table 1 that the correlation between the insurgents and liberal pressure groups is .33?

The second period

What changed in period 2 that helped the farm worker movement? And why did that happen?

The third period

What is offered as evidence of the UFW success in the third period?

How important were UFW strikes in creating this success?

What was the main cause of the UFW success? What is the evidence for Jenkins and Perrow's causal argument?

What role does the government play in promoting change?

Conclusions

What's your one-line summary of Jenkins and Perrow' contribution?
