This paper focuses on the transition to adulthood of Canadian men born from 1916 to 1975. Through a life course framework, six early life events - school completion, work start, home-leaving, cohabitation, first marriage, and first birth - are examined using data from the 1995 Canadian General Social Survey of the Family. The trends in the timing and spread of each event, the length of transition to adulthood, and the trajectories to marriage indicate that the early life courses of Canadian men have changed tremendously with more diversified family behaviours and significant increases in ages at school completion and at start of regular work.

Several demographic trends threaten supportive ties between adult children and elderly parents, including fertility reduction, rising divorce rates, and increasing geographical mobility among young adults. This article focuses on the extent to which proximity of adult children influences several types of social contact between elders and their offspring. Initial analysis uncovered nonlinear patterns in the data. The results of the polynomial regression analyses indicate that physical distance is a potent determinant of several types of social contact. The importance of distance is not affected when statistically controlling for adult children's income, sex, and marital status and elderly respondents' age, sex, education, and ethnicity. The analysis also suggests that substitution occurs between contact types at certain points on the distance continuum.

The first deep borehole determinations of temperature gradients and heat flow on the landward wall of the Japan Trench and forearc were made on IPOD DSDP leg 57. These heat flow values are based on temperature logs corrected to equilibrium, using a detailed model of the drilling disturbance. Heat flow values on a deeply submerged marine terrace, landward of the trench slope break are 28 and 32 mW m−2. A measurement in the midslope terrace basin on the landward wall of the trench yielded a value of 22 mW m−2. The results are in good agreement with earlier seafloor measurements and indicate that most of the forearc area is characterized by heat flow about one half of that over oceanic lithosphere seaward of the trench. Our observations indicate only a small increase of heat flow from the trench to the volcanic arc, in agreement with thermal models, which suggests that the subduction of the relatively cold oceanic plate continues to dominate the temperature structure for distances of up to 250 km landward of the trench. The temperature profile in the borehole on the midslope terrace indicates possible vertical flow of pore waters. Hundreds of conductivity determinations were made using a new technique.
