Knowledge, risk perceptions and condom usage in male sex workers from three Australian cities

The study identifies factors associated with knowledge and perception of risk of HIV/AIDS, as well as attitudes to and usage of condoms by a sample of male sex workers (MSW). One hundred and eighty-five male sex workers completed a self-reported questionnaire, including knowledge about HIV transmission, attitudes to condom use and perceptions and personal susceptibility to HIV and sexually transmitted infection (STI) risk, and a two-week diary recording use of condom during commercial sex encounters. The findings reveal that condom use was found in 77.7% of the encounters with clients and the majority of the respondents perceived themselves to be at no risk for HIV because of sex work. Independent sex workers from Melbourne and workers who owned their place of residence used condoms in a significant lower proportion. Generally speaking, knowledge about the risks associated with AIDS was high, with respondents showing lower knowledge about the risks associated with unprotected receptive or active oral sex. Participants held a positive attitude to condom use; most considered the provisions of condoms to be their responsibility rather than clients; and they were more worried about contracting an STI than HIV. Those who scored higher on the knowledge scale had more positive attitudes to condom use and those who had a more positive attitude to condom use recorded a perceived lower risk of contracting STI but not HIV. The study discusses the relevance of these findings for public health risk reduction and sexual health education campaigns.

Fire fighters' assessments of fireground risk

Fire fighters are often required to work in dynamic and hazardous environments involving a high level of uncertainty. The present study investigated 110 volunteer fire fighters’ assessments of levels of risk associated with a photographic depiction of a typical grassland fire situation. The fire fighters used a standard fire agency risk-rating matrix procedure requiring them to specify the severity of the hazards depicted and the probability of a mishap in order to rate overall level of risk (1 = Low; 4 = Extreme). The risk ratings made by the fire fighters varied greatly. The overall rate of agreement with the risk level rating of the situation made by a panel of expert fire officers (=1, Low) was only 27%. It seems that use of a standard risk-rating matrix procedure by fire fighters at incidents, as recommended currently by many fire agencies, is likely to result in unreliable risk assessments, at least in the absence of effective training in the risk assessment procedure. The 110 volunteers were also asked to identify the total number of potential hazards apparent in five photographs depicting different kinds of emergency incidents. Identifying more hazards was found to be associated with (a) previous personal experience of a ‘near-miss’; and (b) higher levels of education. The findings imply that when faced with identical fire ground situations, individual fire fighters are likely to differ in their situational awareness of hazards and consequent risk assessments.

Sculpting fog: attempting to define "acceptable risk" in emergency services.

There is currently no consensus as to how “acceptable risk” should be defined in emergency service response. Attempts to address this have relied upon the assumption that a probabilistic model of risk can be calculated and that acceptable levels of risk can be determined. Examples of this process can be seen in a number of emergency services, e.g. dynamic risk assessment utilised by a number of fire services.

Safeguarding Australia from cyber-terrorism : a proposed cyber-terrorism SCADA risk framework for Australia

Terrorist groups are currently using information and communication technologies (ICTs) to orchestrate their conventional physical attacks. More recently, terrorists have been developing a new form of capability within the cyber-arena to coordinate cyber-based attacks. This paper identifies that cyber-terrorism capabilities are an integral, imperative, yet under-researched component in establishing, and enhancing cyber-terrorism risk assessment models for SCADA systems. This paper is an extension of work previously published by Beggs and
Warren 2008, it presents a high level overview of a cyber-terrorism SCADA risk framework that has been adopted and validated by SCADA industry practitioners. The paper proposes a managerial framework which is designed to measure and protect SCADA systems from the threat of cyber-terrorism within Australia. The findings and results of an industry focus group are presented in support of the developed framework for SCADA industry adoption and acceptance.

Design-related bias in hospital fall risk screening tool predictive accuracy evaluations: systematic review and meta-analysis.

Introduction: Fall risk screening tools are frequently used as a part of falls prevention programs in hospitals. Design-related bias in evaluations of tool predictive accuracy could lead to overoptimistic results, which would then contribute to program failure in practice.

Methods: A systematic review was undertaken. Two blind reviewers assessed the methodology of relevant publications into a four-point classification system adapted from multiple sources. The association between study design classification and reported results was examined using linear regression with clustering based on screening tool and robust variance estimates with point estimates of Youden Index (= sensitivity + specificity - 1) as the dependent variable. Meta-analysis was then performed pooling data from prospective studies.

Results: Thirty-five publications met inclusion criteria, containing 51 evaluations of fall risk screening tools. Twenty evaluations were classified as retrospective validation evaluations, 11 as prospective (temporal) validation evaluations, and 20 as prospective (external) validation evaluations. Retrospective evaluations had significantly higher Youden Indices (point estimate [95% confidence interval]: 0.22 [0.11, 0.33]). Pooled Youden Indices from prospective evaluations demonstrated the STRATIFY, Morse Falls Scale, and nursing staff clinical judgment to have comparable accuracy.

Discussion: Practitioners should exercise caution in comparing validity of fall risk assessment tools where the evaluation has been limited to retrospective classifications of methodology. Heterogeneity between studies indicates that the Morse Falls Scale and STRATIFY may still be useful in particular settings, but that widespread adoption of either is unlikely to generate benefits significantly greater than that of nursing staff clinical judgment.

Identifying and managing low money laundering risk : perspectives on FATF's risk-based guidance

Purpose – The purpose of this paper is to investigate Financial Action Task Force (FATF)'s risk-based guidance to combat money laundering and terrorist financing to determine its approach to the identification and management of low-risk providers, products and transactions.

Design/methodology/approach – The paper analyses the relevant FATF recommendations and its guidance notes and reflects on key questions for regulators and financial institutions.

Findings – FATF has not defined “risk” for purposes of the risk-based approach. The absence of a clear definition complicates the identification of low-risk products. FATF do provide an example of a risk matrix that can be used to identify low-risk banks, but the example is based on assumptions and generalisations that are not sustainable. In addition, it identifies certain low-value transactions as “low risk” transactions. The paper reflects on the role of value as an indicator of risk and concludes with a number of suggestions to clarify the conceptual framework.

Originality/value – Low-risk products and transactions are often overlooked because the risk-based approach focuses attention on high-risk matters. Low-risk products are however crucial to the efforts to increase financial inclusion. The paper identifies gaps in the current conceptual framework and indicates ways in which they can be addressed.

Confidentiality and disclosure : assessment and intervention issues

This portfolio addresses the moral, ethical and legal issues that impact upon decisions to maintain or disclose confidential communications. The tensions and moral dilemmas that are created when a conflict between these aspects arises are considered. Risk assessment procedures that inform decisions to maintain or disclose confidential information are discussed, as are issues related to the practical implementation of planned interventions. The topic is addressed by firstly reviewing professional codes of conduct and legal requirements to maintain confidentiality. The limits of confidentiality and privileged communication are then reviewed together with legal requirements of “duty to warn” or “duty of care”. These requirements are then related to risk assessment procedures and relevant interventions. Four case studies that illustrate the practical application of assessment techniques in the decision process and planned interventions are presented. They cover such diverse topics as disclosure and suicidal intent, threat of harm to a third party, risk of transmission of the AIDS virus and “duty to warn” and maintenance of a minor’s confidential communications. The ways in which these issues were addressed and the outcome is presented. NOTE: All names and details that have the potential to identify the people whose cases are presented here have been changed to protect their anonymity.

Multi-type maltreatment : relationships between familial characteristics, maltreatment and adjustment of children and adults

This thesis examines the nature, extent and impact of multiple forms of maltreatment (multi-type maltreatment) from within a developmental victimological framework. The interrelationships between sexual abuse, physical abuse, psychological maltreatment, neglect, and witnessing family violence are assessed. The role of family variables in predicting maltreatment and the relative contribution of child maltreatment and family variables to adjustment are evaluated. Risk factors for multi-type maltreatment, and the relationship between multi-type maltreatment and adjustment are explored. The major theories of child development are reviewed. As well as exploring the relevance of developmental theories to understanding the impact of child maltreatment, factors influencing the emergence of child psychopathology are reviewed from a developmental psychopathology perspective. Ecological and developmental perspectives on how child maltreatment translates into the behavioural and emotional adjustment problems of children are integrated in the Child Maltreatment: Risk and Protection Model. After exploring some of the relevant conceptual issues, the literature on the prevalence and impact of each maltreatment type is reviewed, and the literature on multi-type maltreatment critiqued. Methodological and ethical concerns with the conduct of research in the field of child maltreatment using direct assessment of children led to the need for an instrument to assess parent perceptions of each of the types of abuse and neglect, as well as adult retrospective reports. Data are presented from two cross-sectional questionnaire-based studies using the Parent and Adult versions of the Family and Life Experiences Questionnaire which was designed to assess perceptions of children's experiences of sexual abuse, physical abuse, psychological maltreatment, neglect and witnessing family violence. Problems with the isolated focus of research on single forms of child maltreatment are addressed by the inclusion of each of these forms of child maltreatment within a single research design. Respondents for both studies were volunteers recruited from counselling agencies, medical, community health, child care and fitness centres and a first year psychology course. Parents (N=50) described their perceptions of primary school children's family characteristics, experiences of maltreatment and adjustment. Children's behavioural adjustment (internalising and externalising), sexual behaviours, emotions, self-esteem, gender identity, family adaptability and cohesion, parental traditionality, parental sexual punitiveness, interparental relationship satisfaction, and demographic characteristics are assessed in the study of Parents' perceptions. A large degree of overlap between the different types of abuse and neglect was found, with a high proportion of parents describing children's experiences of multiple forms of child maltreatment. Using both maltreatment and family characteristics to predict internalising behaviour problems, neglect and family cohesion were the only unique predictors. Family adaptability and cohesion were the only unique predictors of externalising behaviour problems. Physical and sexual abuse were not predicted from family characteristics; neglect was predicted, but no variables provided unique prediction. Unique predictors of psychological maltreatment were family cohesion, parental sexual punitiveness and divorce. Divorce was the only variable with significant unique prediction of the child witnessing family violence. Family background and family functioning were found to predict some forms of maltreatment, but to also be important factors mediating the adjustment of children, independent of maltreatment. The results are interpreted within an ecological framework, integrating risk factors for maltreatment with experiences of abuse and neglect and subsequent adjustment in childhood. Retrospective reports of adults' (N=175) own childhood family characteristics, experiences of maltreatment, and reports of their current adjustment are also studied. Included with the adult version of the FLEQ were the Trauma Symptom Checklist-40, Rosenberg's Self-esteem Scale, and the Family and Adaptability and Cohesion Evaluation Scale-II. Similar results were found in the in the Adult Study. As hypothesised, adult retrospective reports of the five different types of child maltreatment were found to be highly intercorrelated. Family characteristics predicted maltreatment and adjustment scores and discriminated between single and multi-type maltreatment. Maltreatment scores also predicted adult adjustment. As the number of maltreatment types increased, there was an increase in the number of adjustment problems reported. Alternate hypotheses regarding the possible operation of mediating and moderating processes in the relationships between family characteristics, maltreatment and the adjustment of adults were assessed. Finally, the results of these investigations are discussed and interpreted in the light of extant findings previously reviewed. Data from the two major empirical studies are used to demonstrate the overlap between different child maltreatment categories, and the extent and impact of multi-type maltreatment. The results show that children are vulnerable to more than one type of maltreatment. Individuals who experience a number of different forms of maltreatment had greater adjustment problems than those experiencing only one or two different types of abuse or neglect. Dysfunctional families place children at risk of child maltreatment. Negative family characteristics lead to adjustment problems in children and adults. The type of maltreatment having the most damaging effect on children was neglect, and in the long-term, sexual abuse. A multi-dimensional approach to prevention and intervention needs to be adopted, based on the co-morbidity of maltreatment types, and the likelihood of children experiencing further abuse or neglect of a different type. Dysfunctional family dynamics which place children at risk of multi-type maltreatment, and mediate the effects of maltreatment on adjustment, need to be specifically targeted with support and family intervention strategies. Risk-assessment measures used by Child Protection workers must include adequate knowledge of the inter-relationships between maltreatment types, and the particularly negative impact on adjustment of experiencing many forms of abuse or neglect. Suggestions for future clinical and research work in the area of child maltreatment are developed. The importance of assessing all forms of maltreatment when examining the relationships of maltreatment to adjustment is emphasised. It is recommended that prevention and intervention strategies acknowledge the interrelationships between maltreatment types.

Exposure estimation, uncertainty and variability in occupational hygiene retrospective assessment

This thesis reports on a quantitative exposure assessment and on an analysis of the attributes of the data used in the estimations, in particular distinguishing between its uncertainty and variability. A retrospective assessment of exposure to benzene was carried out for a case control study of leukaemia in the Australian petroleum industry. The study used the mean of personal task-based measurements (Base Estimates) in a deterministic algorithm and applied factors to model back to places, times etc for which no exposure measurements were available. Mean daily exposures were estimated, on an individual subject basis, by summing the task-based exposures. These mean exposures were multiplied by the years spent on each job to provide exposure estimates in ppm-years. These were summed to provide a Cumulative Estimate for each subject. Validation was completed for the model and key inputs. Exposures were low, most jobs were below TWA of 5 ppm benzene. Exposures in terminals were generally higher than at refineries. Cumulative Estimates ranged from 0.005 to 50.9 ppm-years, with 84 percent less than 10 ppm-years. Exposure probability distributions were developed for tanker drivers using Monte Carlo simulation of the exposure estimation algorithm. The outcome was a lognormal distribution of exposure for each driver. These provide the basis for alternative risk assessment metrics e.g. the frequency of short but intense exposures which provided only a minimal contribution to the long-term average exposure but may increase risk of leukaemia. The effect of different inputs to the model were examined and their significance assessed using Monte Carlo simulation. The Base Estimates were the most important determinant of exposure in the model. The sources of variability in the measured data were examined, including the effect of having censored data and the between and within-worker variability. The sources of uncertainty in the exposure estimates were analysed and consequential improvements in exposure assessment identified. Monte Carlo sampling was also used to examine the uncertainties and variability associated with the tanker drivers' exposure assessment, to derive an estimate of the range and to put confidence intervals on the daily mean exposures. The identified uncertainty was less than the variability associated with the estimates. The traditional approach to exposure estimation typically derives only point estimates of mean exposure. The approach developed here allows a range of exposure estimates to be made and provides a more flexible and improved basis for risk assessment.

General practitioners' role in health assessment of humanitarian settlers

An approach to health assessment of humanitarian settlers was developed and evaluated from the perspective of general practitioners (GPs). While conducting assessment was found to be feasible, there were significant barriers which GPs without a primary interest in refugee health and those working in private practice may find difficult to transcend.

Why is type 2 diabetes such a serious risk factor for coronary heart disease in women?

Women with type 2 diabetes were found to display an altered distribution of body fat, higher resistance to the action of insulin, highly increased levels of tryglycerides and significant elevations in the level of plasminogen activator inhibiter. Concludes that interventions which enhance the action of insulin, such as exercise or drug therapy, should lower the risk of coronary heart disease in these women.

Parents' knowledge, attitudes and practices about preventing child sexual abuse: a literature review

Increased concern about high rates of child sexual abuse has led to the demand for more prevention programmes, particularly those aimed at parents. Research on how parents manage and reduce the risk of child sexual abuse can help plan programmes. This literature review explores published research on the knowledge, attitudes and practices of parents on the risk and prevention of child sexual abuse and identifies gaps and needs for further research. The majority of studies reviewed originated in North America and Asia, were quantitative, surveyed mainly mothers and were more than ten years old. Recommendations are made for more current and country specific research, further research to gain a deeper understanding of how parents manage the risk of child sexual abuse, more comprehensive research covering a range of knowledge, attitude and practice variables, and greater inclusion of fathers in research.

Exploring the application of Health Impact Assessment in neighbourhood renewal

This thesis explores the role that Health Impact Assessment can play in social exclusion policy contexts focusing specifically on Victoria's Neighbourhood Renewal Scheme. The findings demonstrate that it can play an important role if due attention is given to contextual and procedural factors both within community settings and within government.
