The role of theory in promoting social work values and its potential effect on outcomes in work with domestically violent men

This article is concerned with the ethical conflicts that arise for social workers when dealing with males that perpetrate violence against women and children with whom they have or had intimate relationships. In particular, the article seeks to highlight how a strong social work value base is essential when working with perpetrators whose apparent wilful violent controlling behaviour creates a major ethical dilemma for the practising social worker. The argument contends that strategies designed to protect and enhance the welfare of domestic violence victims, particularly those aimed at the re-education of perpetrators, are weakened when social workers do not adhere to a social work value base.

Temporal information and children's and adults' causal inferences

Three experiments examined whether children and adults would use temporal information as a cue to the causal structure of a three-variable system, and also whether their judgements about the effects of interventions on the system would be affected by the temporal properties of the event sequence. Participants were shown a system in which two events B and C occurred either simultaneously (synchronous condition) or in a temporal sequence (sequential condition) following an initial event A. The causal judgements of adults and 6-7-year-olds differed between the conditions, but this was not the case for 4-year-olds' judgements. However, unlike those of adults, 6-7-year-olds' intervention judgements were not affected by condition, and causal and intervention judgements were not reliably consistent in this age group. The findings support the claim that temporal information provides an important cue to causal structure, at least in older children. However, they raise important issues about the relationship between causal and intervention judgements.

Avoidance of filial cannibalism in the amphipod Gammarus pulex.

Adult animals that cannibalise juvenile conspecifics may gain energy but also risk filial cannibalism, that is, consumption of their own offspring. However, individuals vary in the magnitude of the costs and benefits of cannibalism depending on factors such as their current energy reserves or the probability that they have offspring in the vicinity. They may therefore also vary in the extent to which they participate in cannibalism. This study investigated whether the sex or brooding status of adult amphipods (Gammarus pulex) influenced whether they participated in cannibalism of juveniles. For females carrying embryos within their brood pouch, we also investigated two hypotheses to explain the presence or absence of cannibalistic behaviour by determining whether cannibalism was correlated with factors that might reflect energy demands (body length, brood size), or that might reflect a temporal change in cannibalistic behaviour (corresponding to stage of brood development). All reproductive classes of adults participated in some level of juvenile cannibalism, but females carrying offspring at an advanced stage of development (close to emergence from the brood pouch) consumed significantly fewer juveniles than other groups. Females thus appear to significantly reduce cannibalism of juveniles concurrent with the time when their own eggs are hatching within the brood pouch, prior to the release of their offspring. Because the experiment tested female responses to unfamiliar juveniles, this reflects a temporal change in behaviour rather than a response to phenotypic recognition cues, although additional direct recognition cannot be ruled out. Brooding females with large brood sizes or large body lengths, which might have disproportionately greater energetic demands, were not more likely to cannibalise juveniles. We also noted that juveniles that survived in trials where cannibalism occurred were significantly more likely to be found at the water surface, suggesting a possible adaptation to escape cannibalistic adults. Overall, our results provide evidence that amphipods use indirect temporal cues to avoid filial cannibalism.

Costing the hospital-based process of resettling people with learning disability in the community

Objectives: Much has been written about the costs and cost-effectiveness of community care for people with learning disabilities resettled from long stay hospital care. However, comparatively little has been published about the cost of hospital services relating to the preparatory process before eventual resettlement and the disengagement of formal, sustained input from hospital staff. This study describes and costs the input provided by a hospital based multi-disciplinary team into the resettlement of adults with learning disabilities, from long stay wards in Muckamore Abbey Hospital in Northern Ireland between 1996 and 1999 (n = 71).
