Changing American home life: trends in domestic leisure and storage among middle-class families

This study of middle-class American families draws on ethnography and urban economic history, focusing on patterns of leisure time and household consumption and clutter. We trace how residential life evolved historically from cramped urban quarters into contemporary middle-class residences and examine how busy working families use house spaces. Our ethnographic sample consists of 24 Los Angeles families in which both parents work full time, have young children, and own their homes. Formal datasets include systematically timed family uses of home spaces, a large digital archive of photographs, and family-narrated video home tours. This analysis highlights a salient home-storage crisis, a marked shift in the uses of yards and garages, and the dissolution of outdoor leisure for busy working parents. The UCLA Center on Everyday Lives of Families (CELF) is generously supported by the Alfred P. Sloan Foundation program on the Workplace, Workforce, and Working Families. Anthony Graesch assisted with the tables. Additional information about CELF can be found at www.celf.ucla.edu.     

Relative blocking in posets

Poset-theoretic generalizations of set-theoretic committee constructions are presented. The structure of the corresponding subposets is described. Sequences of irreducible fractions associated to the principal order ideals of finite bounded posets are considered and those related to the Boolean lattices are explored; it is shown that such sequences inherit all the familiar properties of the Farey sequences. 2000 Mathematics Subject Classification 05A05, 06A07, 11B57, 90C27
