Communities coping with change: A conceptual model

Changing economic, political, environmental, and social conditions continue to have a cumulative impact on Australian regional communities, and in many instances, rural communities are being forced to initiate their own strategies in order to remain economically and socially viable. However, while communities respond in differing ways to similar change events, as do individuals, research examining the change process has largely been undertaken at the individual level. This article reports on an investigation of the characteristics that moderate a community's ability to manage change and the types of collective coping strategies communities employ to deal with change events. A model of community change process was used as the framework to examine the links between community characteristics, appraisal of change events (forest restructuring and tourism), and the use of collective strategies in three communities in Western Australia. Findings suggest that a community's mobilization of strategies is dependent on the collective assessment of the change event, the nature of the event, and the characteristics of the community. The implications for intervention through policy and community development are discussed briefly. © 2004 Wiley Periodicals, Inc. J Comm Psychol 32: 201–216, 2004.     

High intensity focused ultrasound: physical principles and devices.

High intensity focused ultrasound (HIFU) is gaining rapid clinical acceptance as a treatment modality enabling non-invasive tissue heating and ablation for numerous applications. HIFU treatments are usually carried out in a single session, often as a day case procedure, with the patient either fully conscious, lightly sedated or under light general anaesthesia. A major advantage of HIFU over other thermal ablation techniques is that there is no necessity for the transcutaneous insertion of probes into the target tissue. The high powered focused beams employed are generated from sources placed either outside the body (for treatment of tumours of the liver, kidney, breast, uterus, pancreas and bone) or in the rectum (for treatment of the prostate), and are designed to enable rapid heating of a target tissue volume, while leaving tissue in the ultrasound propagation path relatively unaffected. Given the wide-ranging applicability of HIFU, numerous extra-corporeal, transrectal and interstitial devices have been designed to optimise application-specific treatment delivery. Their principle of operation is described here, alongside an overview of the physical mechanisms governing HIFU propagation and HIFU-induced heating. Present methods of characterising HIFU fields and of quantifying HIFU exposure and its associated effects are also addressed.     

Patients with Alcohol Problems in the Emergency Department,Part 1: Improving Detection*

Abstract. Medical and social problems related to alcohol use are frequently seen in the ED. Often, the tempo of emergency medicine practice seems to preclude assessment beyond that required by the acute complaint. However, detection of ED patients with alcohol problems can occur using brief screening tools. This article was developed by members of the SAEM Substance Abuse Task Force, and describes screening tools that have been used successfully to identify atrisk and dependent drinkers. Their brevity, reproducibility, and accuracy vary somewhat, but screening can be realistically performed in the busy ED setting. The early detection of patients with alcohol problems would provide the opportunity for early intervention, and may reduce subsequent morbidity and mortality in this patient population.     

Poxvirus-based vaccine therapy for patients with advanced pancreatic cancer

Purpose  

An open-label Phase 1 study of recombinant prime-boost poxviruses targeting CEA and MUC-1 in patients with advanced pancreatic cancer was conducted to determine safety, tolerability and obtain preliminary data on immune response and survival.     

Waiting: the experience of persons in a critical care waiting room.

The purposes of this study were to discover the essences of the experience of waiting, to provide new knowledge about what it is like to wait, and to contribute to nursing knowledge. Participants were 12 persons who were family members or friends of persons in an adult critical care unit. The Parse research method was used to answer the research question: What is the structure of the lived experience of waiting? The central finding of this study was this structure: The lived experience of waiting is a vigilant attentiveness surfacing amid an ambiguous turbulent lull as contentment emerges with uplifting engagements. The structure is discussed in relation to nursing knowledge and in relation to how it can inform future research and practice. © 2002 John Wiley & Sons, Res Nurs Health 25:58–67, 2002.     

Keeping the focus on public health: the struggles of a tobacco prevention task force.

This case study examines a nonlegislative task force as it struggled to reach internal consensus despite external political constraints. The study highlights the convergence of politics and science, revealing complex issues likely to be confronted by advocates and public health officials. Three themes capture participants' experiences: context, sizing up the opportunities and constraints; task force process, tacit strategy to operate outside the political context and play the science card; and aftermath, a glass half full. The task force took advantage of ambiguous parameters, crafting a comprehensive statewide plan to reduce tobacco use and breaking out of the common public health paradigm of allowing budget considerations to drive program design. These internal victories could not sustain a policy success in the legislature. However, the group's product sets science-based standards for future program development, and the task force's process provides valuable insights into other states developing tobacco prevention and control policies.     

Measurement of Perceived Disruption During Rebuilding Following Hurricane Andrew

The purpose of this study was to develop and evaluate a measure of perceived disruption during rebuilding following a disaster. Two eight-item scales, which measured intensity of disruption during the entire repair phase (Intensity-RP) and intensity of disruption during the past month (Intensity-PM) were developed and administered to 135 survivors of Hurricane Andrew. At 9 to 12 months postdisaster, Intensity-RP and Intensity-PM were both significantly associated with scores on the Global Severity Index of the SCL-90-R, and with scores on the Impact of Event-Intrusion Scale; Intensity-PM alone was significantly associated with PTSD scores. Regression analyses indicated that each scale contributed significant unique variance in predicting mental health symptoms, even after controlling for relevant demographic and initial disaster exposure variables.
