Consensual partnering in Australia: A review and 1991 census profile

This paper is the first part of a two-part examination of consensual partnering in Australia. It reviews the Australian literature on consensual partnering, summarizing evidence of its proliferation since the mid-1960s and also the findings of investigations into its nature and the personal attributes that predispose some people more than others to adopt it. It then discusses the shortcomings of Australian census data as a source for studying consensual unions, before using data from the 1991 Census to present the first elements in a comprehensive profile of the cohabiting population. These cover the basic demography of consensual partnering: the ages, marital statuses and family type distributions of those involved. The second author contributed to this paper while a student of Graduate Studies in Demography, The Australian National University. Views expressed are those of the authors, and are not necessarily those of the Australian Bureau of Statistics.     

Adoption and Antisocial Personality: Genetic and Environmental Factors Associated with Antisocial Outcomes

The present review critically evaluates evidence from adoption studies on the heritability of antisocial personality, interactions between genetic predispositions and the characteristics of adoptive mothers and fathers, and both the methodological and diagnostic shortcomings of existing studies. The article concludes with directions and suggestions for future research and practice.

Choice and circumstance: Qualitative insights into contemporary childlessness in Australia

Using data from in-depth interviews with 115 women, men and couples in eastern Australia for whom family formation was a recent, current or imminent future issue, this article explores contemporary childlessness among those physically able to have children. It differentiates between those childless by choice and by circumstance, and among other themes highlights (i) the role preservation of lifestyle appears to play as a motive for deliberate childlessness following development of a life course through early adulthood that both generates lifestyle aspirations and often places parenthood on the backburner until after age 30, and (ii) the roles difficulty forming suitable relationships, women’s desire for meaningful careers, and male involvement in family formation decisions play in bringing about childlessness by circumstance.     

Is Small Always Beautiful? A Dialogue

For quite a few years the two authors have been engaging in dialogues about management issues. Using as a model Plato's dialogues between Socrates and his various students, we have tried to clarify the nature of a concept by asking questions and thinking carefully about the answers. We disagree about many things, but agree that we respect each other's opinions, and can clarify our own viewpoints by debating them respectfully with another. For this dialogue, we decided to focus on the question of the scale of business operations. One of us has a particular preference for small scale enterprise, and for the localisation of the economy, because he believes that the giganticism of corporations is behind many of the problems we face today. As you will see, the other protagonist disagrees, arguing instead that other issues than scale are at the root of why some businesses do bad things.     

Remarriage Among Divorced Persons in New Zealand

Trends in the remarriage of divorced persons in New Zealand since World War Two are examined with special attention to the period since 1968 during which the divorce rate has risen rapidly. While remarrying divorcees have formed increasing proportions of marriage cohorts since the late 1960s the remarriage rate, especially for females, has risen only because the divorced population has become more youthful. Comparison of the remarriage experience of synthetic divorce cohorts for 1961 and 1976 suggests that the likelihood of remarriage has fallen for both sexes where divorce occurs at ages below forty, but in particular for females divorced in their thirties.     

Calibration of FI‐ISK,an Invasiveness Screening Tool for Nonnative Freshwater Invertebrates

The Freshwater Invertebrate Invasiveness Scoring Kit (FI‐ISK) is proposed as a screening tool for identifying potentially invasive freshwater invertebrates. FI‐ISK was adapted from the Fish Invasiveness Scoring Kit (FISK) of Copp, Garthwaite, and Gozlan, which is an adapted form of the Weed Risk Assessment (WRA) of Pheloung, Williams, and Halloy. Initial assessments using FI‐ISK, which include confidence (certainty/uncertainty) rankings by the assessor to each response, were calibrated to determine the most appropriate score thresholds for classifying nonnative species into low‐, medium‐, and high‐risk categories, using both the original medium‐to‐high risk threshold scores for the WRA (i.e., ≥6) and for FISK (i.e., ≥19). Patterns of the assessor's confidence, when making the responses during the FI‐ISK assessments, were also examined. Using receiver operating characteristic (ROC) curves, FI‐ISK was shown to distinguish accurately (and with statistical confidence) between potentially invasive and noninvasive species of nonnative crayfish (Decapoda: Astacidae, Cambaridae, Parastacidae), with the statistically appropriate threshold score for high‐risk species scores being ≥16. FI‐ISK represents a useful and viable tool to aid decision‐ and policymakers in assessing and classifying freshwater invertebrates according to their potential invasiveness.
