Changing demographics will see an increasing demand for self-funded sector retirement villages in Australia. As such, valuers can expect to be more involved in providing valuation advice in this sector, although the central issue remains that retirement villages are complex businesses. They have been described as management intensive operating businesses with a substantial real estate element. As a result the valuation process in this sector requires a different type of analysis, in comparison to the traditional real estate based investment.
This paper provides an analysis of recent trends in the demand for retirement villages and examine current practise with respect to valuation thereof. It emphasises the need for a greater awareness of the ‘business enterprise value’ component and provides a framework within which the components of value can be better understood. The purpose of the paper is to provide a foundation for a greater reliability with respect to valuation advice.

The current study extends debate and research on the important role of practice in promoting and sustaining complex skills in investigative interviewing. Specifically, we explored the use of self-initiated practice as one avenue for facilitating ongoing development of professionals who interview children about abuse. A group of 40 investigative interviewers were required to organise and administer their own practice opportunities and to document these sessions in a diary. The professionals were aware of the important role of practice and what constitutes best-practice interview guidelines; however no instruction was given about the desired format, structure and timing of the practice sessions. A combination of quantitative and qualitative analyses revealed poor adherence to self-initiated practice, and the practice (among those who adhered to this model) had negligible impact on performance. Overall, these findings highlight the need for careful monitoring and evaluation of all interviewer practice tasks.

‘Psychosocial problems’ are psychological problems that are regarded as resulting from the interaction between the adaptive capacities of individuals and the demands of their physical and social environments. Many different factors have been theoretically proposed, and empirically established, as predictors of a range of psychosocial problems in adolescents. However, a problem exists in that this literature appears to lack an integrative framework that has validity across the range of problems that are observed. The purpose of the current research is to propose and test a model that draws together three clusters of factors that are useful in predicting the incidence of adolescent psychosocial problems. These are family structural background factors, family functioning variables and control beliefs. Data were collected from 155 adolescent males aged between 12 and 19 by a single concurrent and retrospective self-report questionnaire. This included data about the respondent (age, involvements with mental health or juvenile justice agencies) and family structural background factors (days per week worked by mother/father, occupational status for mother/father, residential mobility, number of persons in the family home). The questionnaire also incorporated the Parental Bonding Instrument (Parker, Tupling & Brown, 1979) to quantify the levels of perceived parental care and overprotection, and an adaptation of the Parental Discipline Style Scale (Shaw & Scott, 1991), to assess punitive, love withdrawing and inductive discipline practices. In addition, the (Low) Self-control Scale (Grasmick, Tittle, Bursick & Arneklev, 1993) and the Locus of Control of Behaviour Scale (Craig, Franklin, & Andrews, 1984) were used to collect data concerning adolescents’ perceived behavioural self-control and locus of control. Finally, selected sub-scales of the Child Behavior Checklist Youth Self-Report (Achenbach, 1991b) were used to collect data on the incidence of social withdrawal, somatisation, anxiety and depression, aggression and delinquency among the respondents, and in aggregated form, the incidence of ‘total problems’ and internalising and externalising behaviours. Results indicated family structural background factors, family functioning variables and control beliefs possess limited predicted validity and that the usefulness of the proposed model varies between specific psychosocial problems. Family functioning variables were generally stronger predictors than family structural background factors, particularly for internalising behaviours. Of these, levels of parental care and overprotection were generally the strongest predictors. Perceived self-control and locus of control were also generally strong predictors, but were particularly powerful with respect to externalising behaviours. The strength of predictive relationships was observed to vary between specific internalising and externalising behaviours, suggesting that individual difference variables not assessed in the current research were differentially influential. Finally, the parental and individual characteristics that predicted maximal levels of adjustment (defined in terms of minimal levels of internalising and externalising behaviours) were explored and the correlates of various parenting style typologies (Parker et al., 1979) were investigated. These results strongly confirmed the importance of family functioning and control beliefs with respect to the prediction of internalising, externalising and well-adjusted behaviours. In all analyses, substantial proportions of the variance in the incidence of problem behaviours remain unexplained. The findings are examined in relation to previous research focused on (familial) social control and (individual) self-control with respect to psychosocial problems in adolescents. In addition, methodological considerations are discussed and the implications of the findings for clinical and community interventions to address problem behaviours, and for further study, are explored.

Aims & rationale/Objectives : Chronic disease self-management programs (CDSMP) are increasingly being integrated into the health system to improve the care of people with chronic conditions. Despite activity at both policy and program levels, GPs as the 'gatekeepers' to the health system have generally not been well informed or engaged in this process. This study, in collaboration with 3 Victorian Divisions of General Practice, sought both GP and patient perspectives on enablers and barriers to engagement in self-management programs.
Methods : Interviews were conducted with GPs (n=20) and consumers (n=45) purposefully recruited from metropolitan and rural Victoria, representing key demographics of interest including low socioeconomic areas.
Principal findings : Lack of education/information and uncertainty about the effectiveness of self-management programs were key barriers for both GP and patient engagement. Programs that were sustainable and utilised existing community resources were viewed as enablers to increase uptake. GP and patient preferences for disease specific or generic CDSMP differed.
Discussion : Outcomes from the recent Council of Australian Governments' meeting suggest that self-management will be a centerpiece in forthcoming chronic disease initiatives. International evidence has highlighted the need for GP and patient engagement as critical in ensuring the recruitment of a critical mass of individuals to participate in CDSMP to ensure the sustainability of such initiatives. Insight from this study indicates that GPs and patients are not well informed about self-management, have different preferences to current policy trends and identifies several other barriers which need to be addressed if CDSMP are to be successful.
Implications : Identification of barriers and enablers of GP and patient engagement in self-management is essential in shaping current policy initiatives and delivery of future programs. This is supported by international evidence which indicates strongly that GP engagement in particular is crucial to the success of these programs.

Objective: The growing burden of chronic disease and the increasing realisation that the current health system is ill equipped to deal with this trend has resulted in a health policy shift away from the traditional medical model to a more patient centred approach. As such, chronic disease self-management programs (CDSMP) have emerged as a potentially important component within this approach. Policy and program trends at the international level highlight several critical factors that need to be considered by governments and health care providers alike if CDSMP are to be integrated within the broader health system. This study reviewed international and local policy literature and sought perspectives from key stakeholders to determine the value and potential for integrating a generic group-based CDSMP into the care continuum.
Method: Prominent self-management policies were identified through a comprehensive literature search. Interviews were conducted with policy makers across Australia (n=20), health practitioners (n=20) and consumers (n=42) purposefully recruited from metropolitan and rural Victoria, representing key demographics of interest including low socioeconomic areas.
Results: Whilst CDSMP were viewed as having significant potential to be integrated into the health sector it was identified that the delivery and content of CDSMP needs to be flexible in order to address the needs of people across the disease, age and care continuums. Critical issues to be addressed if CDSMP are to be successfully integrated include increasing the profile of self-management; actively engaging and training health practitioners in self-management and overcoming system barriers such as lack of integrated referral pathways and networks.
Discussion: Policy directions at the national level suggest that self-management will be a centrepiece in forthcoming chronic disease initiatives. International evidence has highlighted the requirement for a ‘suite’ of programs to adequately cater to different stages of the disease continuum, age groups, ethnic backgrounds and sociogeographical areas. Furthermore engagement with key stakeholders (particularly GPs) is identified as critical to ensure the successful integration of CDSMP into the health system.
Conclusion: Evidence suggests that CDSMP is an important facet in improving care of people with chronic conditions. Findings from this study suggest that current infrastructure and policy direction, which have been found to be critical factors in facilitating integration of CDSMP into the health sector, are either absent or inadequate in Victoria. CDSMPs are currently lacking a sustainable workforce, referral infrastructure and specific policy. Such factors need to be addressed before the integration of CDSMP can be considered across the healthcare continuum in Victoria.

The relationship between predisposing risk factors and precipitating life events of individuals presenting to an emergency department with Deliberate Self-Harm was investigated. Poor mental health and childhood abuse were related to suicide intent, only individuals' perceptions regarding their current life events were directly associated with lethality of the self-harm act. The portfolio illustrates the issues inherent in the treatment and management of schizophrenia and the potential of CBT in addressing symptoms and sequelae of acute psychosis. Four case studies are presented.

Influenza A viruses that circulate normally in the human population cause a debilitating, though generally transient, illness that is sometimes fatal, particularly in the elderly. Severe complications arising from pandemic influenza or the highly pathogenic avian H5N1 viruses are often associated with rapid, massive inflammatory cell infiltration, acute respiratory distress, reactive hemophagocytosis and multiple organ involvement. Histological and pathological indicators strongly suggest a key role for an excessive host response in mediating at least some of this pathology. Here, we review the current literature on how various effector arms of the immune system can act deleteriously to initiate or exacerbate pathological damage in this viral pneumonia. Generally, the same immunological factors mediating tissue damage during the anti-influenza immune response are also critical for efficient elimination of virus, thereby posing a significant challenge in the design of harmless yet effective therapeutic strategies for tackling influenza virus.

Aims To examine the self-reported personal wellbeing of a sample of Australian injecting drug users (IDU) using a standardized instrument and determine the key correlates of variations in self-reported personal wellbeing.

Design, setting and participants Cross-sectional survey of 881 Australian IDU.

Measurements
Self-reported personal wellbeing collected using the Personal Wellbeing Index (PWI).

Findings IDU scored significantly lower than the general Australian population on the PWI and all subscales. Lower PWI scores were associated with a range of socio-demographic, drug use and other health and social characteristics. Across all PWI subscales, lower personal wellbeing scores were associated with unemployment, past 6-month mental health problems and more frequent injecting (all P < 0.05).

Conclusions The PWI is sufficiently sensitive to distinguish between IDU and the general population, and to identify key correlates of PWI among IDU. Some domains canvassed within the scale, such as health, standard of living and life achievements, are well within the scope of current intervention strategies, such as pharmacotherapy maintenance treatment and housing and employment support services. This suggests that the PWI could be useful in clinical settings by allowing structured identification of the areas of a person's life to be addressed as a part of a treatment regimen. In order to inform targeted prevention and intervention efforts, longitudinal studies of PWI and its correlates among IDU are required.

Background Irritable bowel syndrome (IBS) is commonly regarded as a functional disorder, and is hypothesized to be associated with anxiety and depression. This evidence mainly rests on population-based studies utilising self-report screening instruments for psychopathology. Other studies applying structured clinical interviews are generally based on small clinical samples, which are vulnerable to biases. The extant evidence base for an association between IBS and psychopathology is hence not conclusive. The aim of this study was therefore to re-examine the hypothesis using population-based data and psychiatric morbidity established with a structured clinical interview.

Methods Data were derived from a population-based epidemiological study (n = 1077). Anxiety and mood disorders were established using the Structured Clinical Interview for DSM-IV-TR (SCID-I/NP) and the General Health Questionnaire (GHQ-12). Current and lifetime IBS was self-reported. Hypertension and diabetes were employed as comparison groups as they are expected to be unrelated to mental health.

Results Current IBS (n = 69, 6.4%) was associated with an increased likelihood of current mood and/or anxiety disorders (OR = 2.62, 95%CI 1.49 - 4.60). Half the population reporting a lifetime IBS diagnosis also had a lifetime mood or anxiety disorder. Exploratory analyses demonstrated an increased prevalence of IBS across most common anxiety and mood disorders, the exception being bipolar disorder. The association with IBS and symptoms load (GHQ-12) followed a curved dose response pattern. In contrast, hypertension and diabetes were consistently unrelated to psychiatric morbidity.

Conclusions IBS is significantly associated with anxiety and mood disorders. This study provides indicative evidence for IBS as a disorder with a psychosomatic aspect.

Anorexia Nervosa has been recently recognized as one of the most common chronic illnesses that affects the female adolescent population today. Although there has been an abundance of research into eating disorders in a variety of fields, significant limitations within the research still exist. Since very early descriptions of the disorder, self-concept and body image have been identified as core components of the anorexia nervosa. However, research has been somewhat limited in that there have not been any consistent theoretical underpinnings for self-concept and body image within the eating disorders field. Furthermore, researchers have tended to adopt traditional inferential statistics and multivariate methods to assess the role of self-concept and body image. As a result there has been very little consistency in research results. The current paper summarizes the significant findings from a doctoral thesis that attempted to address current limitations in self-concept and body image literature within the field of eating disorders.

Traditional and radical authors agree that strengthening the autonomy of service users is a primary aim in casework. The current paper seeks to balance this emphasis on individual autonomy by arguing that the relational aspects of the self also require attention. This argument proceeds in three steps. Firstly, recent theoretical work will be introduced to advance the premise that the self can be understood as ‘relational’ as well as ‘autonomous’. Secondly, a summary is offered of the research which concludes that a strong social network, or in the more recently favoured terms, that ‘social connectedness’ and ‘attachment’, is protective of health and well-being. Building on these two ideas, it is then suggested that it may be important for caseworkers to promote the quality of interdependence and connectedness of those service users with whom we work, irrespective of the presenting problem and the practitioner’s preferred method and assigned practice role.

Purpose – This study aims to explore consumers' motives for their choice of complaint channel in the context of self-service technology (SST) failure. Traditional and evolving communication channels are considered.

Design/methodology/approach – Qualitative self-report data from consumers who had recently experienced dissatisfaction with SSTs were collected via an open-ended survey question. Three independent coders used a deductive and inductive iterative process to code the data.

Findings – The findings suggest that both consumer complaint behaviour (CCB) theory and media richness theory (MRT) help to explain consumers' motivation for channel choice. However, consumers' choice appears to be motivated to a greater degree by convenience rather than task-medium fit.

Research limitations/implications – This study was set solely in the SST context and explored consumers' hypothetical complaint channel choice, not actual channel use. Future research could examine the actual performance of complaint channels as perceived by consumers. Consumers' motivation to choose other emerging electronic complaint channels, such as complaint blogs and forums, could also be explored.

Practical implications – Understanding consumers' complaint channel choice is important for organisations to enable them to provide effective and efficient ways for consumers to complain. As complaint channels proliferate, it is difficult for organisations to know which channels to offer.

Originality/value – Choosing an appropriate channel for resolving a complaint is an important consumer decision, which the study of CCB needs to be broadened to include. The current study addresses this gap by, for the first time, integrating CCB theory and MRT. This is valuable because it is common for consumers not to voice their complaints to organisations. To facilitate voiced complaints, organisations need to determine which complaint channels will be most effective and efficient and in which situations.

Long and straight β-SiC nanowires are synthesized via the direct current arc discharge method with a mixture of silicon, graphite and silicon dioxide as the precursor. Detailed investigations with x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, Raman scattering spectroscopy, transmission electron microscopy and selected area electron diffraction confirm that the β-SiC nanowires, which are about 100–200 nm in stem diameter and 10–20 µm in length, consist of a solid single-crystalline core along the (1 1 1) direction wrapped with an amorphous SiOx layer. A broad photoluminescence emission peak with a maximum at about 336 nm is observed at room temperature. A direct current arc plasma-assisted self-catalytic vapour–liquid–solid process is proposed as the growth mechanism of the β-SiC nanowires. This synthesis technique is capable of producing SiC nanowires free of metal contamination with a preferential growth direction and a high aspect ratio, without the designed addition of transition metals as catalysts.

Youth justice services are increasingly expected to demonstrate that the services and programs they provide lead to measurable outcomes. This paper considers how client outcomes other than recidivism, which are considered important to youth justice service providers, might be conceptualized and reliably assessed. We conclude that there is a need to develop methods of assessment that are consistent with the principles of evidence-based assessment and we make a number of suggestions for the development of practice in this area.

Purpose
To carry out a systematic review of program outcomes used in the evaluation of group-based self-management interventions aimed at people with arthritis and other chronic conditions.

Methods
The systematic search was performed across databases MEDLINE, EMBASE, CINAHL, and PsycINFO. Both between-group and within-group effect sizes (ES) were calculated. Results were interpreted as small (ES ~ 0.2), medium (ES ~ 0.5), or large (ES ~ 0.8) effects.

Results
The majority of 18 included trials investigated the effectiveness of arthritis-specific interventions. Across most outcomes, small effects on course participants were shown. While effects on knowledge were large (between-group ES = 0.78), effects on clinical outcomes such as pain (ES = 0.10) were negligible to small.

Conclusions
This paper is consistent with other reviews in this area, suggesting that people with arthritis receive only marginal benefits from participating in chronic disease self-management interventions. When looking at the types of outcomes that trials are based on, however, alternative explanations for these results seem probable. As evaluations heavily rely on patient self-report, current approaches to program evaluation may not be sufficient to assess the intended impact of self-management education. An in-depth investigation of the types of outcomes assessed is provided in a separate paper.
