Over the past five years, Australia has accepted approximately 50 000 individuals through its Humanitarian program. To integrate these individuals specialised medical and psychological services have been established in major centres of Australia. Australia has been involved in a heated and partisan debate as to the policy of the government in responding to the refugee situation. Regardless of the outcome of the debate, it is imperative that Australia establishes and develops effective policies and processes to respond to the mental health needs of refugees and asylum seekers. To this end, the current review provides an overview of published studies relating to the psychological treatment of refugees and asylum seekers, as well as studies covering the delivery of related services in response to the needs of this group. In this review we aim to provide an informed perspective in terms of research evidence where this is available. Reported research is supported by findings from local focus groups conducted in Queensland, Australia. The overall aim is to provide an optimum response to facilitate the development of effective and humane programs for a significantly disadvantaged group in our community.

Fouling of industrial surfaces by silica and calcium oxalate can be detrimental to a number of process streams. Solution chemistry plays a large roll in the rate and type of scale formed on industrial surfaces. This study is on the kinetics and thermodynamics of SiO2 and calcium oxalate composite formation in solutions containing Mg2+ ions, trans-aconitic acid and sucrose, to mimic factory sugar cane juices. The induction time (ti) of silicic acid polymerization is found to be dependent on the sucrose concentration and SiO2 supersaturation ratio (SS). Generalized kinetic and solubility models are developed for SiO2 and calcium oxalate in binary systems using response surface methodology. The role of sucrose, Mg, trans-aconitic acid, a mixture of Mg and trans-aconitic acid, SiO2 SS ratio and Ca in the formation of com- posites is explained using the solution properties of these species including their ability to form complexes.

Executive Summary The Australian Psychological Society categorically condemns the practice of detaining child asylum seekers and their families, on the grounds that it is not commensurate with psychological best practice concerning children’s development and mental health and wellbeing. Detention of children in this fashion is also arguably a violation of the UN Convention on the Rights of the Child. A thorough review of relevant psychological theory and available research findings from international research has led the Australian Psychological Society to conclude that: • Detention is a negative socialisation experience. • Detention is accentuates developmental risks. • Detention threatens the bonds between children and significant caregivers. • Detention limits educational opportunities. • Detention has traumatic impacts on children of asylum seekers. • Detention reduces children’s potential to recover from trauma. • Detention exacerbates the impacts of other traumas. • Detention of children from these families in many respects is worse for them than being imprisoned. In the absence of any indication from the Australian Government that it intends in the near future to alter the practice of holding children in immigration detention, the Australian Psychological Society’s intermediate position is that the facilitation of short-term and long-term psychological development and wellbeing of children is the basic tenet upon which detention centres should be audited and judged. Based on that position, the Society has identified a series of questions and concerns that arise directly from the various psychological perspectives that have been brought to bear on estimating the effects of detention on child asylum seekers. The Society argues that, because these questions and concerns relate specifically to improvement and maintenance of child detainees’ educational, social and psychological wellbeing, they are legitimate matters for the Inquiry to consider and investigate. • What steps are currently being taken to monitor the psyc hological welfare of the children in detention? In particular, what steps are being taken to monitor the psychological wellbeing of children arriving from war-torn countries? • What qualifications and training do staff who care for children and their families in detention centres have? What knowledge do they have of psychological issues faced by people who have been subjected to traumatic experiences and are suffering high degrees of anxiety, stress and uncertainty? • What provisions have been made for psycho-educational assessment of children’s specific learning needs prior to their attending formal educational programmes? • who are suffering chronic and/or vicarious trauma as a result of witnessing threatening behaviour whilst in detention? • What provisions have been made for families who have been seriously affected by displacement to participate in family therapy? • What critical incident debriefing procedures are in place for children who have witnessed their parents, other family members, or social acquaintances engaging in acts of self-harm or being harmed while in detention? What psychotherapeutic support is in place for children who themselves have been harmed or have engaged in self- harmful acts while in detention? • What provisions are in place for parenting programmes that provide support for parents of children under extremely difficult psychological and physical circumstances? • What efforts are being made to provide parents with the opportunity to model traditional family roles for children, such as working to earn an income, meal preparation, other household duties, etc.? • What opportunities are in place for the assessment of safety issues such as bullying, and sexual or physical abuse of children or their mothers in detention centres? • How are resources distributed to children and families in detention centres? • What socialization opportunities are available either within detention centres or in the wider community for children to develop skills and independence, engage in social activities, participate in cultural traditions, and communicate and interaction with same-age peers and adults from similar ethnic and religious backgrounds? • What access do children and families have to videos, music and entertainment from their cultures of origin? • What provisions are in place to ensure the maintenance of privacy in a manner commensurate with usual cultural practice? • What is the Government’s rationale for continuing to implement a policy of mandatory detention of child asylum seekers that on the face of it is likely to have a pernicious impact on these children’s mental health? • In view of the evidence on the potential long-term impact of mandatory detention on children, what processes may be followed by Government to avoid such a practice and, more importantly, to develop policies and practices that will have a positive impact on these children’s psychological development and mental health?

This literature review was developed as background for the formulation of an Australian Psychological Society position on the mental health and wellbeing of refugees resettling in Australia. The major aim is to provide a broad overview of the concerns related to refugee mental health and wellbeing within the Australian context. To begin, a brief overview of the definition of a refugee and the scope of refugee movement is provided. Next, the review examines the pre-displacement, post-displacement, systemic and socio-political factors that influence the process of adaptation in refugee resettlement. It then reviews documented approaches to psychological assessment and therapeutic interventions with refugees; and finally it summarises suggestions for assessment and intervention in these practice contexts.

This study used a video-based hazard perception dual task to compare the hazard perception skills of young drivers with middle aged, more experienced drivers and to determine if these skills can be improved with video-based road commentary training. The primary task required the participants to detect and verbally identify immediate hazard on video-based traffic scenarios while concurrently performing a secondary tracking task, simulating the steering of real driving. The results showed that the young drivers perceived fewer immediate hazards (mean = 75.2%, n = 24, 19 females) than the more experienced drivers (mean = 87.5%, n = 8, all females), and had longer hazard perception times, but performed better in the secondary tracking task. After the road commentary training, the mean percentage of hazards detected and identified by the young drivers improved to the level of the experienced drivers and was significantly higher than that of an age and driving experience matched control group. The results will be discussed in the context of psychological theories of hazard perception and in relation to road commentary as an evidence-based training intervention that seems to improve many aspects of unsafe driving behaviour in young drivers.

Health care interventions in the area of body image disturbance and eating disorders largely involve individual treatment approaches, while prevention and health promotion are relatively underexplored. A review of health promotion activities in the area of body image in Australia revealed three programmes, the most extensive and longest standing having been established in 1992. The aims of this programme are to reduce body image dissatisfaction and inappropriate eating behaviour, especially among women. Because health promotion is concerned with the social aspects of health, it was hypothesized by the authors that a social understanding of body image and eating disorders might be advanced in a health promotion setting and reflected in the approach to practice. In order to examine approaches to body image in health promotion, 10 health professionals responsible for the design and management of this programme participated in a series of semi-structured interviews between 1997 and 2000. Three discursive themes were evident in health workers' explanations of body image problems: (1) cognitive-behavioural themes; (2) gender themes; and (3) socio-cultural themes. While body image problems were constructed as psychological problems that are particularly experienced by women, their origins were largely conceived to be socio-cultural. The implications of these constructions are critically discussed in terms of the approach to health promotion used in this programme.

The natural and built environment has been shown to affect its users in both psychological and physiological forms. But can if affect the sociological aspects of human processes and actions? The activation of the public realm can be shown to reduce socially dysfunctional behaviour through the simple occupation of the space and a number of other key variables through its design. In order to explore this further we must study how public space is being used in terms of social interaction, which will lead to a set of design ideals through which the social activation of public space can be achieved. Observations of differing social contexts have been undertaken in order to solidify key ideas and design principles for the activation of public space. Three sites were selected, each containing different amounts of vegetation and opportunity for occupation. These were then analysed through a lens of levels of social interaction. In this way it can become evident how the users interact with and within their social environments Through the analysis of the chosen sites, it has become evident that levels of interaction between the users, whether for transitory or occupational purposes, rise directly with vegetation and opportunity for occupation. With this in mind it can be determined that through design, public space can allow for and create greater opportunity for social interaction.

The rapid growth of visual information on Web has led to immense interest in multimedia information retrieval (MIR). While advancement in MIR systems has achieved some success in specific domains, particularly the content-based approaches, general Web users still struggle to find the images they want. Despite the success in content-based object recognition or concept extraction, the major problem in current Web image searching remains in the querying process. Since most online users only express their needs in semantic terms or objects, systems that utilize visual features (e.g., color or texture) to search images create a semantic gap which hinders general users from fully expressing their needs. In addition, query-by-example (QBE) retrieval imposes extra obstacles for exploratory search because users may not always have the representative image at hand or in mind when starting a search (i.e. the page zero problem). As a result, the majority of current online image search engines (e.g., Google, Yahoo, and Flickr) still primarily use textual queries to search. The problem with query-based retrieval systems is that they only capture users’ information need in terms of formal queries;; the implicit and abstract parts of users’ information needs are inevitably overlooked. Hence, users often struggle to formulate queries that best represent their needs, and some compromises have to be made. Studies of Web search logs suggest that multimedia searches are more difficult than textual Web searches, and Web image searching is the most difficult compared to video or audio searches. Hence, online users need to put in more effort when searching multimedia contents, especially for image searches. Most interactions in Web image searching occur during query reformulation. While log analysis provides intriguing views on how the majority of users search, their search needs or motivations are ultimately neglected. User studies on image searching have attempted to understand users’ search contexts in terms of users’ background (e.g., knowledge, profession, motivation for search and task types) and the search outcomes (e.g., use of retrieved images, search performance). However, these studies typically focused on particular domains with a selective group of professional users. General users’ Web image searching contexts and behaviors are little understood although they represent the majority of online image searching activities nowadays. We argue that only by understanding Web image users’ contexts can the current Web search engines further improve their usefulness and provide more efficient searches. In order to understand users’ search contexts, a user study was conducted based on university students’ Web image searching in News, Travel, and commercial Product domains. The three search domains were deliberately chosen to reflect image users’ interests in people, time, event, location, and objects. We investigated participants’ Web image searching behavior, with the focus on query reformulation and search strategies. Participants’ search contexts such as their search background, motivation for search, and search outcomes were gathered by questionnaires. The searching activity was recorded with participants’ think aloud data for analyzing significant search patterns. The relationships between participants’ search contexts and corresponding search strategies were discovered by Grounded Theory approach. Our key findings include the following aspects: - Effects of users' interactive intents on query reformulation patterns and search strategies - Effects of task domain on task specificity and task difficulty, as well as on some specific searching behaviors - Effects of searching experience on result expansion strategies A contextual image searching model was constructed based on these findings. The model helped us understand Web image searching from user perspective, and introduced a context-aware searching paradigm for current retrieval systems. A query recommendation tool was also developed to demonstrate how users’ query reformulation contexts can potentially contribute to more efficient searching.

Although advances in technology now enable people to communicate 'anytime, anyplace', it is not clear how citizens can be motivated to actually do so. This paper evaluates the impact of three principles of psychological empowerment, namely perceived self-efficacy, sense of community and causal importance, on public transport passengers' motivation to report issues and complaints while on the move. A week-long study with 65 participants revealed that self-efficacy and causal importance increased participation in short bursts and increased perceptions of service quality over longer periods. Finally, we discuss the implications of these findings for citizen participation projects and reflect on design opportunities for mobile technologies that motivate citizen participation.

Background The International Society for Heart and Lung Transplantation recommended in 2006 that intervention studies to maximize psychological outcomes after transplantation should be conducted. Potentially, studies reporting on the effectiveness of non-pharmacological interventions in improving psychological outcomes for heart transplant recipients may have been published since the call for this research. Thus, further evidence may currently be available to inform policy and practice decision-making regarding the implementation of such interventions. Accordingly, an evaluation of the evidence is required. Objectives The objective of this review was to identify the effectiveness of non-pharmacological interventions on psychological outcomes for heart transplant recipients.

Receiving emotional support has consistently been demonstrated as an important factor associated with mental health but sparse research has investigated giving support in addition to receiving it or the types of support that predict well-being. In this paper the relationship between giving and receiving instrumental and emotional social support and psychological well-being during and following a natural disaster is investigated. A survey administered between four and six months after fatal floods was conducted with 200 community members consisting of men (n = 68) and women (n = 132) aged between 17 and 87 years. Social support experiences were assessed using the 2-Way Social Support Scale (2-Way SSS; Shakespeare-Finch & Obst, 2011) and eudemonic well-being was measured using the Psychological Well-Being Scale (PWBS; Ryff & Keyes, 1995). Hierarchical multiple regression analyses were used to examine expected relationships and to explore the differential effects of the four factors of the 2-Way SSS. Results indicated that social support shared significant positive associations with domains of psychological well-being, especially with regards to interpersonal relationships. Receiving and giving emotional support were respectively the strongest unique predictors of psychological well-being. However, receiving instrumental support predicted less autonomy. Results highlight the importance of measuring social support as a multidimensional construct and affirm that disaster response policy and practice should focus on emotional as well as instrumental needs in order to promote individual and community psychosocial health following a flooding crisis.
