Population Policies in Developed Countries: How do Australia’S Policies Compare?

This paper compares international population policies with respect to population growth, fertility and immigration, and discusses current attitudes to the demographic situation in developed countries. Only Canada, the United States and Australia have a policy of continuing high immigration, and Australia’s migrant intake per head of population is considerably higher than for the other two countries. An emerging philosophy in Britain and Europe is a focus on “child quality” and the well-being of a near stationary population, rather than continued population growth. There is also an awareness that immigration is not a solution to the ageing “problem” and that there are more efficient non-demographic means of coping with an older population.     

Dynamics of some special populations with NRR = 1

We discuss two special cases of population dynamics with changing vital rates subject to the constraint NRR = I and consider the specifics of ergodicity and stationarity. By restricting the number of age groups to two, we can make explicit the way weak ergodicity works. When mortality is constant and the period NRR = I, a life-table stationary population eventually results; everything of demographic interest (except age-specific fertility and the cohort NRR) is asymptotically constant. With changing mortality, but both period and cohort NRR = 1, only weak ergodicity holds, and everything changes over time.     

Sexual and physical child abuse and the developtnent of dissociative personality traits. Canadian and British evidence from adolescent child welfare and child care populations

An attempt was made to construct a measure of dissociative personality traits from file review of 61 Canadian adolescents with a known history of sexual abuse before the age of six. The study was then extended to 55 British adolescents in residential care and therapy centres. Between 18 and 29% of adolescents displayed several features of dissociative personality, implying the possibility of multiple personality disorder. Those with two or more indicators of dissociative personality style tended to have more problematic behavioural histories, including a particularly high prevalence of deliberate self-harm. In the UK group the Dissociative Experiences Scale (Bernstein and Putnam, 1986) completed by 55 adolescents correlated 0.67 with the dissociative personality trait index constructed from case file review. Implications for treatment of abused children are discussed.
