Cultural preferences and economic constraints: the living arrangements of elderly Canadians.

ABSTRACTUsing data from the 2001 Census Public Use Microdata Files on Individuals, we examine the role of cultural preferences and economic constraints in elderly Canadians' choice of living arrangements (living with one's children and/or other relatives versus living independently). We find that members of ethnic groups holding familistic cultural values (Italian, Chinese, South Asian, and East Indian) are more likely than their individualistic counterparts (British, German, and Dutch) to live with kin. Economic disadvantage also entails a greater likelihood of living with kin.

Eddies in a bottleneck: an arbitrary Debye length theory for capillary electroosmosis.

Using an applied electrical field to drive fluid flows becomes desirable as channels become smaller. Although most discussions of electroosmosis treat the case of thin Debye layers, here electroosmotic flow (EOF) through a constricted cylinder is presented for arbitrary Debye lengths (kappa(-1)) using a long wavelength perturbation of the cylinder radius. The analysis uses the approximation of small potentials.
