Exact ages of emergence of the twenty deciduous teeth have been investigated on a longitudinal sample of 195 French-Canadian children (113 boys and 82 girls). A multivariate analysis of variance yielded a significant overall sex difference (p less than 0.0001). It has been found that the emergence of the deciduous dentition in boys is more precocious than that in girls by about one month; this difference is present at the emergence of the upper central incisor and is maintained henceforth. The only notable exception to this pattern is the emergence of the first molars. Results of the present study, combined with those of previous research, suggest that sexual dimorphism in the emergence of the deciduous teeth could be mediated through ethnic factors.

In recent years, the institution of marriage in Muslim Central Asia has undergone profound transformations in terms of religious dynamics, migration patterns, and the impact of globalization. In Kazakhstan between 2014 and 2019, every third marriage ended in divorce. By examining how Muslim Kazakhs’ support for divorce and casual sex is related to their consumption of information obtained on the Internet, mobile phone, and social media, this study contributes to the growing body of literature on the transformative forces of information and communication technology (ICT) in Kazakhstan and Central Asia. It uses a mixed-method approach that contrasts wider statistical trends from the World Values Survey Wave 7 country dataset on Kazakhstan with empirical data from focus groups conducted in five different regions of the country in 2019, involving a total of 96 respondents. The findings from the statistical and non-statistical analysis show that frequent exposure to information online influences Muslim Kazakhs’ support for extramarital affairs and divorce. Yet, frequent use of ICTs does not necessarily weaken the institution of marriage. Apart from its effect on university-educated female Kazakh youth, it seems to reinforce traditional understanding of marriage obligations among older generations and young men.
