Submission to National Inquiry into Children in Immigration Detention from The Australian Psychological Society

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?

Foot ulcer simulation training (FUST) : are podiatrists FUST with long-term clinical confidence?

Background Foot ulcers are a leading cause of diabetes-related hospitalisations. Clinical training has been shown to be beneficial in foot ulcer management. Recently, improved self-confidence in podiatrists was reported immediately after foot ulcer simulation training (FUST) pilot programs. This study aimed to investigate the longer-term impacts of the FUST program on podiatrists’ self-confidence over 12 months in a larger sample. Methods Participants were podiatrists attending a two-day FUST course comprising web-based interactive learning, low-fidelity part-tasks and high-fidelity full clinical scenarios. Primary outcome measures included participants’ self-confidence measured pre-, (immediately) post-, 6-month post- and 12-month post-course via a purpose designed 21-item survey using a five-point Likert scale (1=Very limited, 5=Highly confident). Participants’ perceptions of knowledge gained, satisfaction, relevance and fidelity were also investigated. ANOVA and post hoc tests were used to test any differences between groups. Results Thirty-four participants completed FUST. Survey response rates were 100% (pre), 82% (post), 74% (6-month post), and 47% (12-month post). Overall mean scores were 3.13 (pre), 4.49 (post), 4.35 (6-month post) and 4.30 (12-month post) (p < 0.05); post hoc tests indicated no differences between the immediately, 6-month and 12-month post group scores (p > 0.05). Satisfaction, knowledge, relevance and fidelity were all rated highly. Conclusion This study suggests that significant short-term improvements in self-confidence to manage foot ulcers via simulation training are retained over the longer term. It is likely that improved self-confidence leads to improved foot ulcer clinical practice and outcomes; although this requires further research.

Assessment of freestanding membranes prepared from Antheraea pernyi silk fibroin as a potential vehicle for corneal epithelial cell transplantation

Freestanding membranes created from Bombyx mori silk fibroin (BMSF) offer a potential vehicle for corneal cell transplantation since they are transparent and support the growth of human corneal epithelial cells (HCE). Fibroin derived from the wild silkworm Antheraea pernyi (APSF) might provide a superior material by virtue of containing putative cell- attachment sites that are absent from BMSF. Thus we have investigated the feasibility of producing transparent, freestanding membranes from APSF and have analysed the behaviour of HCE cells on this material. No significant differences in cell numbers or phenotype were observed in short term HCE cell cultures established on either fibroin. Production of transparent freestanding APSF membranes, however, proved to be problematic as cast solutions of APSF were more prone to becoming opaque, displayed significantly lower permeability and were more brittle than BMSF-membranes. Cultures of HCE cells established on either membrane developed a normal stratified morphology with cytokeratin pair 3/12 being immuno-localized to the superficial layers. We conclude that while it is feasible to produce transparent freestanding membranes from APSF, the technical difficulties associated with this biomaterial, along with an absence of enhanced cell growth, currently favours the continued development of BMSF as a preferred vehicle for corneal cell transplantation. Nevertheless, it remains possible that refinement of techniques for processing APSF might yet lead to improvements in the handling properties and performance of this material.

Long-term stability of adipose tissue generated from a vascularized pedicled fat flap inside a chamber

Background Numerous studies demonstrate the generation and short-term survival of adipose tissue; however, long-term persistence remains elusive. This study evaluates long-term survival and transferability of de novo adipose constructs based on a ligated vascular pedicle and tissue engineering chamber combination. Methods Defined adipose tissue flaps were implanted into rats in either intact or perforated domed chambers. In half of the groups, the chambers were removed after 10 weeks and the constructs transferred on their vascular pedicle to a new site, where they were observed for a further 10 weeks. In the remaining groups, the tissue construct was observed for 20 weeks inside the chamber. Tissue volume was assessed using magnetic resonance imaging and histologic measures, and constructs were assessed for stability and necrosis. Sections were assessed histologically and for proliferation using Ki-67. Results At 20 weeks, volume analysis revealed an increase in adipose volume from 0.04 ± 0.001 ml at the time of insertion into the chambers to 0.27 ± 0.004 ml in the closed and 0.44 ± 0.014 ml in the perforated chambers. There was an additional increase of approximately 10 to 15 percent in tissue volume in flaps that remained in chambers for 20 weeks, whereas the volume of the transferred tissue not in chambers remained unaltered. Histomorphometric assessment of the tissues documented no signs of hypertrophy, fat necrosis, or atypical changes of the newly generated tissue. Conclusion This study presents a promising new method of generating significant amounts of mature, vascularized, stable, and transferable adipose tissue for permanent autologous soft-tissue replacement.

Long-term persistence of tissue-engineered adipose flaps in a murine model to 1 year : an update

BACKGROUND Tissue engineering of patient-specific adipose tissue has the potential to revolutionize reconstructive surgery. Numerous models have been described for the production of adipose tissue with success in the short term, but little has been reported on the stability of this tissue-engineered fat beyond 4 months. METHODS A murine model of de novo adipogenesis producing a potentially transplantable adipose tissue flap within 4 to 6 weeks was developed in the authors' laboratory. In this study, the authors assess the ability of three-chamber (44-μl volume) configurations shown to be adipogenic in previous short-term studies (autograft, n = 8; open, n = 6; fat flap, n = 11) to maintain their tissue volume for up to 12 months in vivo, to determine the most adipogenic configuration in the long term. RESULTS Those chambers having the most contact with existing vascularized adipose tissue (open and fat flap groups) showed increased mean adipose tissue percentage (77 ± 5.6 percent and 81 ± 6.9 percent, respectively; p < 0.0007) and volume (12 ± 6.8 μl and 30 ± 14 μl, respectively; p < 0.025) when compared with short-term controls and greater adipose tissue volume than the autograft (sealed) chamber group (4.9 ± 5.8 μl; p = 0.0001) at 1 year. Inclusion of a vascularized fat flap within the chamber produced the best results, with new fat completely filling the chamber by 1 year. CONCLUSIONS These findings demonstrate that fat produced by tissue engineering is capable of maintaining its volume when the appropriate microenvironment is provided. This has important implications for the application of tissue-engineering techniques in humans.

Gene electrotransfer into murine skeletal muscle: A systematic analysis of parameters for long-term gene expression

Skeletal muscle is an attractive target tissue for delivery of therapeutic genes, since it is well vascularized, easily accessible, and has a high capacity for protein synthesis. For efficient transfection in skeletal muscle, several protocols have been described, including delivery of low voltage electric pulses and a combination of high and low voltage electric pulses. The aim of this study was to determine the influence of different parameters of electrotransfection on short-term and long-term transfection efficiency in murine skeletal muscle, and to evaluate histological changes in the treated tissue. Different parameters of electric pulses, different time lags between plasmid DNA injection and application of electric pulses, and different doses of plasmid DNA were tested for electrotransfection of tibialis cranialis muscle of C57BI/6 mice using DNA plasmid encoding green fluorescent protein (GFP). Transfection efficiency was assessed on frozen tissue sections one week after electrotransfection using a fluorescence microscope and also noninvasively, followed by an in vivo imaging system using a fluorescence stereo microscope over a period of several months. Histological changes in muscle were evaluated immediately or several months after electrotransfection by determining infiltration of inflammatory mononuclear cells and presence of necrotic muscle fibers. The most efficient electrotransfection into skeletal muscle of C57BI/6 mice in our experiments was achieved when one high voltage (HV) and four low voltage (LV) electric pulses were applied 5 seconds after the injection of 30 μg of plasmid DNA. This protocol resulted in the highest short-term as well as long-term transfection. The fluorescence intensity of the transfected area declined after 2-3 weeks, but GFP fluorescence was still detectable 18 months after electrotransfection. Extensive inflammatory mononuclear cell infiltration was observed immediately after the electrotransfection procedure using the described parameters, but no necrosis or late tissue damage was observed. This study showed that electric pulse parameters, time lag between the injection of DNA and application of electric pulses, and dose of plasmid DNA affected the duration of transgene expression in murine skeletal muscle. Therefore, transgene expression in muscle can be controlled by appropriate selection of electrotransfection protocol.

An adaptive appearance-based map for long-term topological localization of mobile robots

"This work considers a mobile service robot which uses an appearance-based representation of its workplace as a map, where the current view and the map are used to estimate the current position in the environment. Due to the nature of real-world environments such as houses and offices, where the appearance keeps changing, the internal representation may become out of date after some time. To solve this problem the robot needs to be able to adapt its internal representation continually to the changes in the environment. This paper presents a method for creating an adaptive map for long-term appearance-based localization of a mobile robot using long-term and short-term memory concepts, with omni-directional vision as the external sensor."--publisher website

Long-term outcomes following Medtronic Open Pivot valved conduit

Aortic root replacement is a complex procedure, though subsequent modifications of the original Bentall procedure have made surgery more reproducible. The study aim was to examine the outcomes of a modified Bentall procedure, using the Medtronic Open PivotTM valved conduit. Whilst short-term data on the conduit and long-term data on the valve itself are available, little is known of the long-term results with the valved conduit. Patients undergoing aortic root replacement between February 1999 and February 2010, using the Medtronic Open Pivot valved conduit were identified from the prospectively collected Cardiothoracic Register at The Prince Charles Hospital, Brisbane, Australia. All patients were followed up echocardiographically and clinically. The primary end-point was death, and a Cox proportional model was used to identify factors associated.with survival. Secondary end-points were valve-related morbidity (as defined by STS guidelines) and postoperative morbidity. Predictors of morbidity were identified using logistic regression. A total of 246 patients (mean age 50 years) was included in the study. The overall mortality was 12%, with actuarial 10-year survival 79% and a 10-year estimate of valve-related death of 0.04 (95% CI: 0.004, 0.07). Preoperative myocardial infarction (p = 0.004, HR 4.74), urgency of operation (p = 0.038, HR 2.8) and 10% incremental decreases in ejection fraction (p = 0.046, HR 0.69) were predictive of mortality. Survival was also affected by the valve gradients, with a unit increase in peak gradient reducing mortality (p = 0.021, HR 0.93). Valve-related morbidity occurred in 11 patients. Urgent surgery (p <0.001, OR 4.12), aortic dissection (p = 0.015, OR 3.35), calcific aortic stenosis (p = 0.016, OR 2.35) and Marfan syndrome (p 0.009, OR 3.75) were predictive of postoperative morbidity. The reoperation rate was 1.2%. The Medtronic Open Pivot valved conduit is a safe and durable option for aortic root replacement, and is associated with low morbidity and 10-year survival of 79%. However, further studies are required to determine the effect of valve gradient on survival.

Review of the long-term disability associated with hip fractures

Objectives To determine the proportion of hip fracture patients who experience long-term disability and to re-estimate the resulting burden of disease associated with hip fractures in Australia in 2003. Methods A literature review of the functional outcome following a hip fracture (keywords: morbidity, treatment outcome, disability, quality of life, recovery of function, hip fractures, and femoral neck fractures) was carried out using PubMed and Ovid MEDLINE. Results A range of scales and outcome measures are used to evaluate recovery following a hip fracture. Based on the available evidence on restrictions in activities of daily living, 29% of hip fracture cases in the elderly do not reach their pre-fracture levels 1 year post-fracture. Those who do recover tend to reach their pre-fracture levels of functioning at around 6 months. These new assumptions result in 8251 years lived with disability for hip fractures in Australia in 2003, a 4.5-fold increase compared with the previous calculation based on Global Burden of Disease assumptions that only 5% of hip fractures lead to long-term disability and that the duration of short-term disability is just 51 days. Conclusions The original assumptions used in burden of disease studies grossly underestimate the long-term disability from hip fractures. The long-term consequences of other injuries may similarly have been underestimated and need to be re-examined. This has important implications for modelling the cost-effectiveness of preventive interventions where disability-adjusted life years are used as a measure of health outcome.

Incentivising tenants to stay the term – will clawbacks be enforceable?

Incentives are commonly offered by commercial landlords to tenants in the form of short term rent deductions or contributions to the tenant’s fitout. Usually these incentives are conditional upon the lessee remaining in the premises for the term of the lease with an obligation on the tenant to repay a proportion of the fitout contribution and rent deductions upon early termination or assignment. While the enforceability of clawback provisions has always been unclear, there was commercial benefit to landlords in maintaining high rentals on the face of the lease and attracting good quality tenants through fitout contributions. The use of clawback provisions as part of these incentives was recently analysed by the Queensland Supreme Court through the lens of the penalties doctrine in GWC Property Group Pty Ltd v Higginson & Ors [2014] QSC 264, with a negative outcome for the landlord. Unless the decision is overturned on appeal, the salient message for landlords is that repayment of incentives for any reason, not just a breach of the lease, is unlikely to be enforceable.

Channel selection in the short-time modulation domain for distant speech recognition

Automatic speech recognition from multiple distant micro- phones poses significant challenges because of noise and reverberations. The quality of speech acquisition may vary between microphones because of movements of speakers and channel distortions. This paper proposes a channel selection approach for selecting reliable channels based on selection criterion operating in the short-term modulation spectrum domain. The proposed approach quantifies the relative strength of speech from each microphone and speech obtained from beamforming modulations. The new technique is compared experimentally in the real reverb conditions in terms of perceptual evaluation of speech quality (PESQ) measures and word error rate (WER). Overall improvement in recognition rate is observed using delay-sum and superdirective beamformers compared to the case when the channel is selected randomly using circular microphone arrays.

Long-term use of custom-made orthopedic shoes: A 1.5-year follow-up study

This study investigated long-term use of custom-made orthopedic shoes (OS) at 1.5 years follow-up. In addition, the association between short-term outcomes and long-term use was studied. Patients from a previously published study who did use their first-ever pair of OS 3 months after delivery received another questionnaire after 1.5 years. Patients with different pathologies were included in the study (n = 269, response = 86%). Mean age was 63 ± 14 years, and 38% were male. After 1.5 years, 87% of the patients still used their OS (78% frequently [4-7 days/week] and 90% occasionally [1-3 days/week]) and 13% of the patients had ceased using their OS. Patients who were using their OS frequently after 1.5 years had significantly higher scores for 8 of 10 short-term usability outcomes (p-values ranged from <0.001 to 0.046). The largest differences between users and nonusers were found for scores on the short-term outcomes of OS fit and communication with the medical specialist and shoe technician (effect size range = 0.16 to 0.46). We conclude that patients with worse short-term usability outcomes for their OS are more likely to use their OS only occasionally or not at all at long-term follow-up.

Topical tacrolimus in atopic dermatitis : Effects of long-term treatment on skin and respiratory symptoms

Objective: Patients with atopic dermatitis often have a poor long-term response to conventional topical or systemic treatments. Staphylococcal superinfections, skin atrophy due to corticosteroid use, and asthma and allergic rhinitis are common. Only a few, usually short-term, studies have addressed the effects of different treatments on these problems. Tacrolimus ointment is the first topical compound suitable for long-term treatment. The aim of this thesis was to evaluate the effects of long-term topical tacrolimus treatment on cutaneous staphylococcal colonization, collagen synthesis, and symptoms and signs of asthma and allergic rhinitis. Methods: Patients with moderate-to-severe atopic dermatitis were treated with intermittent 0.1% tacrolimus ointment in prospective, open studies lasting for 6 to 48 months. In Study I, cutaneous staphylococcal colonization was followed for 6 to 12 months. In Study II, skin thickness and collagen synthesis were followed by skin ultrasound and procollagen I and III propeptide concentrations of suction blister fluid samples for 12 to 24 months and compared with a group of corticosteroid-treated atopic dermatitis patients and with a group of healthy subjects. Study III was a cross-sectional study of the occurrence of respiratory symptoms, bronchial hyper-responsiveness, and sputum eosinophilia in atopic dermatitis patients and healthy controls. In Study V, the same parameters as in Study III were assessed in atopic dermatitis patients before and after 12 to 48 months of topical tacrolimus treatment. Study IV was a retrospective follow-up of the effect of tacrolimus 0.03% ointment on severe atopic blepharoconjunctivitis and conjunctival cytology. Results: The clinical response to topical tacrolimus was very good in all studies (p≤0.008). Staphylococcal colonization decreased significantly, and the effect was sustained throughout the study (p=0.01). Skin thickness (p<0.001) and markers of collagen synthesis (p<0.001) increased in the tacrolimus-treated patients significantly, whereas they decreased or remained unchanged in the corticosteroid-treated controls. Symptoms of asthma and allergic rhinitis (p<0.0001), bronchial hyper-responsiveness (p<0.0001), and sputum eosinophilia (p<0.0001) were significantly more common in patients with atopic dermatitis than in healthy controls, especially in subjects with positive skin prick tests or elevated serum immunoglobulin E. During topical tacrolimus treatment the asthma and rhinitis (p=0.005 and p=0.002) symptoms and bronchial hyper-responsiveness (p=0.02) decreased significantly, and serum immunoglobulin E and sputum eosinophils showed a decreasing trend in patients with the best treatment response. Treatment of atopic blepharoconjunctivitis resulted in a marked clinical response and a significant decrease in eosinophils, lymphocytes, and neutrophils in the conjunctival cytology samples. No significant adverse effects or increase in skin infections occurred in any study. Conclusions: The studies included in this thesis, except the study showing an increase in skin collagen synthesis in tacrolimus-treated patients, were uncontrolled, warranting certain reservations. The results suggest, however, that tacrolimus ointment has several beneficial effects in the long-term intermittent treatment of atopic dermatitis. Tacrolimus ointment efficiently suppresses the T cell-induced inflammation of atopic dermatitis. It has a normalizing effect on the function of the skin measured by the decrease in staphylococcal colonization. It does not cause skin atrophy as do corticosteroids but restores the skin collagen synthesis in patients who have used corticosteroids. Tacrolimus ointment has no marked systemic effect, as the absorption of the drug is minimal and decreases along with skin improvement. The effects on the airway: decrease in bronchial hyper-responsiveness and respiratory symptoms, can be speculated to be caused by the decrease in T cell trafficking from the skin to the respiratory tissues as the skin inflammation resolves, as well as inhibition of epicutaneous invasion of various antigens causing systemic sensitization when the skin barrier is disrupted as in atopic dermatitis. Patients with moderate-to-severe atopic dermatitis seem to benefit from efficient long-term treatment with topical tacrolimus.

A Comparison of Managers’ Perception of Short-Termism in Finland, Sweden and the U.S

Increased media exposure to layoffs and corporate quarterly financial reporting have created arguable a common perception – especially favored by the media itself – that the companies have been forced to improve their financial performance from quarter to quarter. Academically the relevant question is whether companies themselves feel that they are exposed to short-term pressure to perform even if it means that they have to compromise company’s long-term future. This paper studies this issue using results from a survey conducted among the 500 largest companies in Finland. The results show that companies in general feel moderate short-term pressure, with reasonable dispersion across firms. There seems to be a link between the degree of pressure felt, and the firm’s ownership structure, i.e. we find support for the existence of short-term versus long-term owners. We also find significant ownership related differences, in line with expectations, in how such short-term pressure is reflected in actual decision variables such as the investment criteria used.

Discovery of novel glitazones incorporated with phenylalanine and tyrosine: Synthesis, antidiabetic activity and structure-activity relationships

We report a series of new glitazones incorporated with phenylalanine and tyrosine. All the compounds were tested for their in vitro glucose uptake activity using rat-hemidiaphragm, both in presence and absence of insulin. Six of the most active compounds from the in vitro screening were taken forward for their in vivo triglyceride and glucose lowering activity against dexamethazone induced hyperlipidemia and insulin resistance in Wistar rats. The liver samples of rats that received the most active compounds, 23 and 24, in the in vivo studies, were subjected to histopathological examination to assess their short term hepatotoxicity. The investigations on the in vitro glucose uptake, in vivo triglyceride and glucose lowering activity are described here along with the quantitative structure-activity relationships.
