To marry or not to marry: marital status and the household division of labour

Data from an Australian national survey (1996 to 1997) are used to examine domestic labor patterns among de facto and married men and women. The results show that women spend more time on housework and do a greater proportion of housework than men. However, the patterns are most traditional among married men and women. Women in de facto relationships spend less time doing housework and do a smaller proportion of indoor activities than married women. Men in de facto relationships do a larger proportion of indoor activities and a lower proportion of outdoor tasks than married men. The data also show that couples who have cohabited prior to marriage have more egalitarian divisions of labor than those who have not cohabited prior to marriage. This article concludes by arguing that the incompleteness of the de facto relationship provides a period of relative freedom in which to negotiate more equal roles.

Increased use of emergency services by older people after health screening

Background: evaluation of the 'Keep Well At Home' (KWAH) Project in West London indicated that a programme of screening persons aged 75 and over had not reduced rates of emergency attendances and admissions to hospital. However, coverage of the target population was incomplete. The present analysis addresses 'efficacy'-whether individuals who completed the screening protocol as intended did subsequently use Accident & Emergency (A&E) services less often. Methods: the target population was divided into five groups, depending on whether an individual had completed none, one or both phases of screening, and whether deviations from the protocol related to incomplete coverage or refusal to participate further. We ascertained use of emergency services before screening and for up to 3 years afterwards by linkage of records from KWAH to those of local A&E Departments. Patterns of emergency care were examined as crude races and, via proportional hazards models, after adjustment for available confounders. Results: there was an increase of 51% (95% CI 22-86%) in the crude rate of emergency admissions in the year after first-phase screening compared with the 12 months before assessment. This was most obvious in individuals deemed at high risk who also underwent the second-phase assessment (adjusted hazard ratio relative to individuals not 'at risk'= 2.33; 95% CI 1.59-3.42). Conclusions: the available data do not allow us to distinguish between several possible explanations for the paradoxical increase in use of emergency services. However, what seem to be sensible policies do not necessarily have their intended effects when implemented in practice.

Division of labour within cooperatively breeding groups

Within cooperative societies, group members share in caring for offspring. Although division of labour among group members has been relatively well studied in insects, less is known about vertebrates. Most studies of avian helping focus solely on the extent to which helpers provision the offspring, however, helpers can participate in everything from nest building to predator defence. Bad provisioners may, for example, not be as 'uncooperative' as they appear. if they are good defenders. Thus, the distribution of helping tasks between group members should have important implications for our interpretation of group dynamics. Here, we compare two distinct forms of helping behaviour in the cooperatively breeding noisy miner (Manorina melanocephala): chick provisioning and mobbing nest predators. We show that the way in which individual helpers invest in these two helping behaviours varies enormously across individuals and among social groups. Good provisioners often contributed relatively little to mobbing and vice versa. Indeed, (18%) of helpers only mobbed, 22% just provisioned, whereas 60% of helpers performed both forms of helping. Across nests, provisioning was significantly negatively correlated with mobbing effort. We suggest that small differences in the costs or benefits of different aspects of helping (due to differences in age, relatedness or social status) have a big impact on the division of labour within a group. Consequently, social groups can be made up from individuals who often specialise in one helping behaviour, and/or helpers who perform a number of behaviours to differing degrees. Division of labour within social groups will, therefore, have important consequences for the maintenance of cooperatively breeding in vertebrates.

Psychology in practice: Guidelines for the provision of psychological services for older adults

The practice of psychology covers the range of ages from conception through to the end of life and palliative care. Psychologists practice in a variety of roles, but the majority of these roles involve interactions with nonprofessionals of varying ages. These interactions are governed by codes of ethical practice, whether these are developed by the funding bodies for research activities, professional associations, or regulatory bodies. Ethical codes vary in their format and emphasis, but all have the protection of the public as a major purpose. Often there are special provisions in these codes for particular populations or circumstances. Here we describe the development of ethical guidelines for the practice of psychology with older adults in Australia and report on those guidelines and their supporting literature.
