Why are backlash politics so prevalent in the context of demographic change? And so that we may understand how to mitigate social conflict, what role do government and political actors play in their inflammation or reconciliation? Drawing from a larger study of six societies that have dealt with significant demographic change, I review the ways that government and political leaders’ actions can produce three different social cleavages: (1) an overriding and enduring cleavage between ethnic constituencies in national politics, (2) an overriding cleavage that is suppressed by political actors, or (3) a new definition of social cleavages that re-constructs public understandings of the nation. I find that the drivers of these different trajectories relate to state actions in the construction of national identities, which either exclude certain subgroups or absorb them into a state of coexistence. I identify five ways governments channel backlash politics towards exclusion or coexistence, and provide examples from Hawai‘i, a case where historical cleavages between natives and immigrants nearly disappeared. Ultimately, I find that these politics are subject to competing understandings of the nation – the pivotal sense of ‘we’ – that can unite or divide a multiethnic society.

The injector to be described is a component in the Electron Injector-Linear Accelerator—Condenser Module for illumination used on the variable 100-500kV electron microscope being built at the Radio Corporation of America for the University of Virginia.The injector is an independently powered, autonomous unit, operating at a constant 6kV positive with respect to accelerator potential, thereby making beam current independent of accelerator potential. The injector provides for on-axis ion trapping to prolong filament lifetime, and incorporates a derived Einzel lens for optical integration into the overall illumination system for microscopy. Electrostatic beam deflectors for alignment are an integral part of the apparatus. The entire injector unit is cantilevered off a door for side loading, and is topped with a 4-filament turret released electrically but driven by a self-contained Negator spring motor.
