Death, Divorce and Defective Drafting

Death and Divorce: the Long-term Consequences of Parental Loss*

Two quasi-experiments are used to estimate the impact of parental divorce on the adult incomes and labour market behaviour of children, as well as on their use of social programs, and their marital/fertility behaviour. These involve the use of individuals experiencing the death of a parent, and legislative changes to the Canadian divorce law in 1986. Parental loss by death is assumed to be exog...

Drafting with Sequences

The numbers on the inner circle are those that exist in the modular arithmetic. If we continue beyond 7, as shown in the outer ring, the numbers wrap around the wheel. Numbers on the same spoke are equivalent. For example, 0 and 8 are equivalent, 1 and 9 are equivalent, 2 and 10 are equivalent, and so on. Another way to look at it is that when 9 is introduced into modular arithmetic with 8 shaf...

Father Death and Adult Success among the Tsimane: Implications for Marriage and Divorce.

Human fathers are heavily involved in the rearing of children around the world. Early evolutionary explanations focused on the greater need of human children and mothers compared to other species and the consequent increased benefits available to investing fathers and pairbonded husbands. Contrary to this hypothesis, research suggests that the impact of men's care on the survivorship and physic...

Logical Representations in Drafting and CAD Systems

In this paper we present a logical language for representing and reasoning about drawings in the context of interactive computer graphics. We discuss the motivation for this kind of representation in graphics systems and its applications to geometric reasoning and constraint satisfaction. A formal deenition of the language and its interpretation process is presented and illustrated. The theoret...
