Instrumental measures of bite forces associated with crisp products

Abstract: The usefulness of a bite force apparatus for measuring bite forces generated while biting extruded crisp snacks was assessed. Snacks were produced using a twin-screw extruder, and their textural properties were modified by equilibrating to water activities ranging from 0.11 to 0.44. Maximum force to bite, stress, duration and area under the bite force curve were analyzed and compared to perceived sensory crispness, hardness, brittleness and sound duration evaluated by eight individuals. Maximum bite force and stress were significantly related to hardness, brittleness and crispness showing for the first time, and the relationship between sensory crispness of extruded crisp products and hardness was measured intraorally.

Total Dual Integrality of Linear Inequality Systems

Abstract: Let A be a rational m × n matrix and b be a rational m-vector. The linear system Ax ≤ b is said to be totally dual integral (TDI) if for all integer n-vectors c, the dual of the linear program max{cx : Ax≤b} has an integer-valued optimum solution if it has an optimum solution. We consider two topics: First we discuss the theoretical aspects of total dual integrality. Second, we survey several classes of TDI linear systems and show how the general properties of total dual integrality appy to each class.

Gender and work: The occupational expectations of young women and men in the 1990s

Abstract: This article uses data from a longitudinal survey of youth to examine the effects of gender on the occupational expectations and attitudes of youth in the 1990s. Twelve hundred youth from central and eastern Canada were surveyed in 1989 and 1994. Results show few gender differences in the status rankings in the youths' expected occupations, or in their intentions to enter the paid labour force. However, there were differences in the ways females and males saw themselves combining work and family responsibilities—especially pre-school aged children. The attitudes and experiences of the young women's mothers appeared to affect these plans—plans that were unrelated to social class background. The results are discussed in the context of McCall's notion on gendered dispositions.
