In recent times, police policy makers have been encouraged to use public opinion surveys to identify, and target the allocation of resources to, activities that members of the public believe are important. However, these surveys have concentrated on the types of problems that the public would like addressed, and have not determined what types of activities they would prefer the police to be undertaking. In the present study, a comprehensive list of police activities formed the basis of a survey used to examine attitudes toward police priorities in Australia. Comparisons were made between police and public understanding of the police role, and between present and preferred priorities. The results suggest that the public has an understanding of policing which differs from that of police officers. However, the picture of what they want police to be doing is similar to that of the police, albeit giving higher priorities to almost all of the activities. Police managers may need to educate the public about the functions of the police service, emphasizing functions other than investigating crime and providing advice. At the same time, the police may need to alter their resource allocation and modify organizational structure and reward systems to encourage operational officers to be more involved in the activities that the public see as high priority. This should result in better ties with the community, a better understanding within the community of the police role, and more realistic expectations on both sides of the outcomes of policing. Public perceptions of the police roleTwo recent reviews of community attitude surveys highlighted the fact that very few studies of public perceptions of the police role are reported in the This research was supported by the police departments of Australia and New Zealand and the Australian Federal Attorney-General's Department. The authors would like to thank Carlene Wilson and two anonymous reviewers for their suggestions for earlier drafts of this paper.

What is known about this topic• Elder abuse is an important public health and societal problem which requires a response from both the primary healthcare and social service sectors.• Current knowledge about the effectiveness of many of these approaches is limited.• There is a need to identify evidence-based interventions. What this paper adds• Identifies a body of empirical research that evaluates prevention interventions.• No accounts of multi-modal interventions addressing key risk factors at the level of the elder person were identified.• There is currently insufficient evidence to guide the implementation of interventions that prevent abuse. AbstractAlthough there is increasing concern about both the prevalence of, and harms associated with the abuse of older adults, progress in the development of interventions to prevent its occurrence has been slow. This paper reports the findings of a systematic review of the published literature that identified studies in which the outcomes of preventative interventions are described. A total of eight different intervention trials, published since 2004, are described across the primary, secondary and tertiary levels of prevention and in terms of the types of risk factor that they target. The current evidence to support the effectiveness of these interventions is not only limited by the small number of outcome studies but also the poor quality of evaluation designs and the focus of many interventions on single risk factors. It is concluded that work is needed to strengthen the evidence base that supports the delivery of interventions to prevent elder abuse.

The prognostic significance of post-anoxic-ischemic alpha coma (AC) is controversial. We recorded somatosensory evoked potentials (SEPs) and performed serial electroencephalography (EEG) in a 60-year-old woman in coma after cardiac arrest. The first EEG was recorded after 48 hours (GCS=5; E1-V1-M3); brain-stem reflexes were preserved. The EEG pattern showed monotonous alpha frequencies (10-11 Hz) with posterior predominance; acoustic and noxious stimuli evoked EEG reactivity. Early cortical SEPs (72 h) were normal. On the fifth day (GCS=8; E4-V1-M3), the EEG alpha pattern was replaced by a diffuse delta activity; rhythmic theta changes appeared spontaneously or in response to stimuli. The patient regained consciousness on the tenth day and EEG showed posterior theta activity (6-7 c/s) partially reactive to stimuli. At the 6-month follow-up, cognitive evaluation showed mild dementia. Recent studies identified two forms of AC. Patients with complete AC have an outcome that is almost invariably poor. Conversely, incomplete AC (posteriorly accentuated alpha frequency, reactive and with SEPs mostly normal) reflects a less severe degree of anoxic-ischemic encephalopathy. The case we report should be classified, according to the SEPs and EEG features, as incomplete AC. The fact that the patient has regained consciousness, even if with residual cognitive impairment, confirms the need to distinguish this variant from complete AC.
