A Quiet Revolution: Developmental Psychopathology as a Cutting Edge
                        Framework for Understanding Abuse and Neglect

AbstractThe Quiet Revolution is commonly regarded as the single most important turning point in Quebec's recent history. This article questions the conventional paradigm that the institutional and structural changes in Quebec during the 1960s were merely symptoms of, and secondary to, the essence of the Quiet Revolution, that is, widespread changes of mentality, attitudes and values. The authors argue that the changes encompassed by the Quiet Revolution are not as complete as many have suggested and that the tension between the forces of tradition and the forces of modernity is still an important focus for understanding contemporary Quebec. More specifically, empirical data confirm that the push for secularization in Quebec, secularization being the cutting edge of the Quiet Revolution, has not run its course and that traditional religious values continue to play an important role in Quebec politics.

Geometrical Constraints

The output of the ultramicrotomy process with its high strain levels is dependent upon the input, ie., the nature of the material being machined. Apart from the geometrical constraints offered by the rake and clearance faces of the tool, each material is free to deform in whatever manner necessary to satisfy its material structure and interatomic constraints. Noncrystalline materials appear to survive the process undamaged when observed in the TEM. As has been demonstrated however microtomed plastics do in fact suffer damage to the top and bottom surfaces of the section regardless of the sharpness of the cutting edge or the tool material. The energy required to seperate the section from the block is not easily propogated through the section because the material is amorphous in nature and has no preferred crystalline planes upon which defects can move large distances to relieve the applied stress. Thus, the cutting stresses are supported elastically in the internal or bulk and plastically in the surfaces. The elastic strain can be recovered while the plastic strain is not reversible and will remain in the section after cutting is complete.
