Electrical Engineering and Systems Science - Image and Video Processing - Abstract
Optical coherence elastography allows the characterization of the mechanical properties of tissues, and can be performed through estimating local displacement maps from subsequent acquisitions of a sample under different loads. This displacement estimation is limited by noise in the images, which can be high in dynamic systems due to the inability to perform long exposures or B-scan averaging. In this work, we propose a framework for simultaneously enhancing both the image quality and displacement map for elastography, by motion compensated denoising with the block-matching and 4D filtering (BM4D) method, followed by a re-estimation of displacement. We adopt the interferometric synthetic aperture microscopy (ISAM) method to enhance the lateral resolution away from the focal plane, and use sub-pixel cross correlation block matching for non-uniform deformation estimation. We validate this approach on data from a commercial spectral domain optical coherence tomography system, whereby we observe an enhancement of both image and displacement accuracy of up to 33% over a standard approach., Comment: 7 pages, 6 figures, presented at SPIE BiOS 2019

Mason, Jonathan and Hachena, Narjess
- Abstract
This paper presents a two-year pedagogical, teacher-as-researcher, action research project at the Faculty of Arts and Humanities, University of Sousse, Tunisia, which investigates how the integration of the Soliya Connect Program, a facilitated dialogic online exchange programme, with a theoretical course on critical intercultural communication helped students develop critical interculturality. Despite some initial concern about the extra time commitment, students were unanimously positive about integrating the two aspects, claiming that the Connect Program helped them to develop criticality in real life, and that the online communication was much more effective because they participated with the critical perspective developed in class. The findings support the integration of theoretical and practical online components in developing students' critical intercultural communication skills, and the use of action research to inform adjustments to both components in order to improve the outcomes.

- Abstract
Background: Intellectual disability and mental health disorders constitute a major health problem globally with higher economic burden in low- and middle-income countries such as Bangladesh. In 2017, the World Bank estimated that 85% of the global population lived in low-middle-income countries. Limited research has explored health practitioner knowledge and/or confidence in the diagnosis and treatment of mental health issues in persons with intellectual disabilities (IDs) in low-income countries such as Bangladesh. Method: One hundred and ninety-seven Bangladeshi-based health practitioners were grouped into 7 main professional groups according the current Bangladeshi health hierarchy (psychiatrists; traditional healers and community workers; medical doctors; nurses; psychologists; allied health: speech therapists, occupational therapists, social workers; and others: teachers physiotherapists, administration staff). A 34-item online survey was completed, which included questions measuring symptoms of common mental health disorders with reference to the Psychiatric Assessment Schedule for Adults with Developmental Disabilities, and questions measuring confidence working with persons with IDs from the Therapy Confidence Scale-Intellectual Disabilities. Results: Participants demonstrated low knowledge of symptomology but were "confident" working with people with IDs. Kruskal-Wallis H tests indicated a significant effect of professional group on both overall knowledge and confidence levels, respectively. Traditional healers and community health workers had significantly more knowledge of symptoms than all other practitioners for obsessive-compulsive disorder, depression, psychosis, and hypomania. Conclusion: Participants demonstrated confidence, but low knowledge, in treating individuals with IDs. The development of training programs to address specific deficits in knowledge of mental health symptoms, and confidence in using assessment and assessment-based communication, is recommended.

Electrical Engineering and Systems Science - Image and Video Processing ,Physics - Medical Physics ,Physics - Optics - Abstract
We present a computational method for full-range interferometric synthetic aperture microscopy (ISAM) under dispersion encoding. With this, one can effectively double the depth range of optical coherence tomography (OCT), whilst dramatically enhancing the spatial resolution away from the focal plane. To this end, we propose a model-based iterative reconstruction (MBIR) method, where ISAM is directly considered in an optimization approach, and we make the discovery that sparsity promoting regularization effectively recovers the full-range signal. Within this work, we adopt an optimal nonuniform discrete fast Fourier transform (NUFFT) implementation of ISAM, which is both fast and numerically stable throughout iterations. We validate our method with several complex samples, scanned with a commercial SD-OCT system with no hardware modification. With this, we both demonstrate full-range ISAM imaging, and significantly outperform combinations of existing methods., Comment: 17 pages, 7 figures.

Physics - Medical Physics - Abstract
Scatter can account for large errors in cone-beam CT (CBCT) due to its wide field of view, and its complicated nature makes its compensation difficult. Iterative polyenergetic reconstruction algorithms offer the potential to provide quantitative imaging in CT, but they are usually incompatible with scatter contaminated measurements. In this work, we introduce a polyenergetic convolutional scatter model that is directly fused into the reconstruction process, and exploits information readily available at each iteration for a fraction of additional computational cost. We evaluate this method with numerical and real CBCT measurements, and show significantly enhanced electron density estimation and artifact mitigation over pre-calculated fast adaptive scatter kernel superposition (fASKS). We demonstrate our approach has two levels of benefit: reducing the bias introduced by estimating scatter prior to reconstruction; and adapting to the spectral and spatial properties of the specimen., Comment: 28 pages, 12 figures

Physics - Medical Physics - Abstract
Quantifying material mass and electron density from computed tomography (CT) reconstructions can be highly valuable in certain medical practices, such as radiation therapy planning. However, uniquely parameterising the X-ray attenuation in terms of mass or electron density is an ill-posed problem when a single polyenergetic source is used with a spectrally indiscriminate detector. Existing approaches to single source polyenergetic modelling often impose consistency with a physical model, such as water--bone or photoelectric--Compton decompositions, which will either require detailed prior segmentation or restrictive energy dependencies, and may require further calibration to the quantity of interest. In this work, we introduce a data centric approach to fitting the attenuation with piecewise-linear functions directly to mass or electron density, and present a segmentation-free statistical reconstruction algorithm for exploiting it, with the same order of complexity as other iterative methods. We show how this allows both higher accuracy in attenuation modelling, and demonstrate its superior quantitative imaging, with numerical chest and metal implant data, and validate it with real cone-beam CT measurements., Comment: 23 pages, 12 figures

12. Can Planning Images Reduce Scatter in Follow-Up Cone-Beam CT?

Mason, Jonathan, Perelli, Alessandro, Nailon, William, and Davies, Mike
- Subjects
Physics - Medical Physics - Abstract
Due to its wide field of view, cone-beam computed tomography (CBCT) is plagued by large amounts of scatter, where attenuated photons hit the detector, and corrupt the linear models used for reconstruction. Given that one can generate a good estimate of scatter however, then image accuracy can be retained. In the context of adaptive radiotherapy, one usually has a low-scatter planning CT image of the same patient at an earlier time. Correcting for scatter in the subsequent CBCT scan can either be self consistent with the new measurements or exploit the prior image, and there are several recent methods that report high accuracy with the latter. In this study, we will look at the accuracy of various scatter estimation methods, how they can be effectively incorporated into a statistical reconstruction algorithm, along with introducing a method for matching off-line Monte-Carlo (MC) prior estimates to the new measurements. Conclusions we draw from testing on a neck cancer patient are: statistical reconstruction that incorporates the scatter estimate significantly outperforms analytic and iterative methods with pre-correction; and although the most accurate scatter estimates can be made from the MC on planning image, they only offer a slight advantage over the measurement based scatter kernel superposition (SKS) in reconstruction error., Comment: 13 pages, submitted to Medical Image Understanding and Analysis (MIUA) 2017 conference

Background: Many people require additional care and support to meet their personal, health and psychosocial needs. Sometimes that responsibility falls to young people within their families. The research to date indicates that the impact on these young people can be significant, however no comprehensive reviews have yet examined this in Australian participants. Objective: Given the personal, subjective experience of caring, this study systematically reviews the qualitative literature on Australian youth under 25 who provide an informal caring role, using a meta-ethnographic approach. Method: Qualitative studies published since 2002 using Australian participants were included. The databases used included: Psychology and Behavioural Sciences Collection, PsycInfo, PsycArticles, MEDLINE Complete, Academic Search Complete, CINAHL, and Child Development & Adolescent Studies. Quality ratings and risk of bias are discussed. Results: Seventeen studies were included in the final analysis, representing the experiences of 531 young carers. The results suggest that the young carer experience is profound and impacts a range of domains, including social, academic, and psychological. The impacts are largely perceived as disadvantageous, although some positive outcomes are discussed. Conclusion: On the basis of the findings, the review concludes by offering a model to conceptualise the Australian young carer phenomenon. KEY POINTS: What is already known about this topic: (1) Young carers perform a wide variety of important social, personal and healthcare tasks for family members. (2) Being a young carer impacts physical and mental health, as well as academic and vocational prospects. (3) Structural health and social care differences make international comparisons of the young carer experience difficult to undertake reliably. What this topic adds: (1) Systematically collected and synthesised qualitative information on Australian young carers is presented for the first time. (2) Key themes relating to how they became young carers, their disconnection from support services and the psychosocial toll of undertaking the caring role emerged as important aspects of the young carer experience. (3) Positive aspects of the young carer experience also emerged, but these require further study, alongside factors that mediate the impact of negative health and psychosocial outcomes.

Sexual wellbeing is an integral part of human existence, characterised by physical, emotional, mental, and sociocultural factors. This study aimed to synthesise and evaluate psychometric measures of sexual wellbeing. Following systematic review methodology, searches were conducted in August 2020 and articles were screened by two independent reviewers. Studies regarding adult sexual wellbeing (≥18 years old), that also met eligibility criteria, were identified and relevant psychometric measures were extracted. A total of 74 unique measures were extracted from 88 papers, representing varying aspects of sexual wellbeing. Sexual wellbeing instruments were categorised by domains (e.g., cognitive-affective) and dimensions (e.g., sexual function, sexual desire), and reliability was summarised. The overall psychometric properties demonstrate that current measures are acceptable, although no single measure captured all domains of sexual wellbeing reflected in the literature. Rather, many instruments measured a single dimension of the multifaceted construct with variation amongst what constituted "sexual wellbeing". A unified approach to sexual wellbeing is needed to ensure clear operational definitions and theoretical frameworks are used to support psychometric evaluation. Clinicians and researchers are urged to critically evaluate which instrument best captures the desired aspects of sexual wellbeing or whether a combination of measures would be more appropriate. LAY SUMMARY: The current study investigated how sexual wellbeing has been examined by researchers within the wider literature. Interestingly, our results found that sexual wellbeing has largely been measured inconsistently, using a variety of questionnaires that only assess one part of sexual wellbeing (e.g., only sexual desire or only sexual functioning). New ways of measuring sexual wellbeing are required to ensure sexual wellbeing is accurately assessed. [ABSTRACT FROM AUTHOR]

Mason, Jonathan
- Abstract
The Paris and San Bernardino attacks in autumn 2015, along with various retaliatory incidents, and Donald Trump's suggestion that Muslims should be banned from entering the US, have reminded us again of the deep misunderstandings and resentments that often exist between the Muslim and Western worlds. In order to improve intercultural and interreligious understanding, students at the University of Sousse, Tunisia, took part in an online exchange programme with students from Villanova University in Pennsylvania, USA. Using student diaries and end of course reflection exercises, this study investigated both the benefits and limits that the exchange had in developing understanding, as well as the impact the process had on the outcomes. The findings showed numerous positive developments in intercultural and interreligious understanding, but also limits to the depth of discussion, particularly concerning conflict situations. The diaries also revealed some cases of limited communication, which undermined some of the benefits of the exchange. [For the complete volume, see ED571330.]

- Abstract
Introduction: Intellectual disability (ID) and co-morbid mental health problems are more common in developing countries such as Bangladesh. However, little is known about how Bangladeshi health practitioners diagnose mental health disorders in people with an ID. Studies in developed countries have explored the impact of the diagnostic overshadowing bias (DOB): the tendency for health practitioners to misattribute mental health symptomology to a client's ID, rather than a separate mental health disorder. To date, no study has investigated the presence of the DOB in Bangladesh. Method: A range of Bangladeshi health practitioners (N = 243) were randomly assigned a clinical vignette describing a client displaying symptoms of a mental health disorder. Vignette 1 described a client with an IQ of 105 who graduated from secondary school. Vignette 2 described a client with an IQ of 55 who attended special education. All other details were identical. Participants rated the likelihood of seven mental health diagnoses on a 5-point Likert scale. Results: Practitioners were more likely to diagnose schizophrenia, drug problems and being bullied in people with a typical IQ compared to those with an ID. Doctors, psychiatrists, and psychologists appeared to be more affected by the DOB than community health workers, traditional healers, and allied health practitioners. Conclusion: Findings indicate that the bias may be present in Bangladesh healthcare professionals. The development and implementation of specific training programs to meet the differing needs of practitioners, across the health fields are recommended.

Radiotherapy planning involves the calculation of dose deposition throughout the patient, based upon quantitative electron density images from computed tomography (CT) scans taken before treatment. Cone beam CT (CBCT), consisting of a point source and flat panel detector, is often built onto radiotherapy delivery machines and used during a treatment session to ensure alignment of the patient to the plan. If the plan could be recalculated throughout the course of treatment, then margins of uncertainty and toxicity to healthy tissues could be reduced. CBCT reconstructions are normally too poor to be used as the basis of planning however, due to their insufficient sampling, beam hardening and high level of scatter. In this work, we investigate reconstruction techniques to enable dose calculation from CBCT. Firstly, we develop an iterative method for directly inferring electron density from the raw X-ray measurements, which is robust to both low doses and polyenergetic artefacts from hard bone and metallic implants. Secondly, we supplement this with a fast integrated scatter model, also able to take into account the polyenergetic nature of the diagnostic X-ray source. Finally, we demonstrate the ability to provide accurate dose calculation using our methodology from numerical and physical experiments. Not only does this unlock the capability to perform CBCT radiotherapy planning, offering more targeted and less toxic treatment, but the developed techniques are also applicable and beneficial for many other CT applications.

Hinde, Kylie and Mason, Jonathan
- Abstract
Background: There is limited Australian research investigating health practitioner knowledge and/or confidence in the diagnosis and treatment of mental health disorders in people with intellectual disabilities (IDs). Method: Ninety-three health practitioners from four professional groups (primary health practitioners, psychologists, mental health practitioners, and alternative therapies) completed a 34-item online survey comprising questions designed to identify participant knowledge of disorders described in the Psychiatric Assessment Schedule for Adults with Developmental Disabilities and the Therapy Confidence Scale-Intellectual Disabilities. Results: Participants demonstrated low knowledge of symptomology and were "moderately confident" to "confident" working with people with IDs. Whilst professional group showed a significant main effect on confidence levels, post-hoc analysis did not detect significant differences between the individual professional groups. Conclusions: Australian participants demonstrated confidence, but low knowledge, in treating individuals with IDs. The development of training to address deficits in practitioner knowledge of symptomology, assessment, and assessment-based communication is recommended.

ObjectiveMethodResultsDiscussion\nKEY POINTSThe experience of psychologists who use telehealth remains relatively unexplored. Existing literature indicates that self-efficacy and familiarity with technology contribute to satisfaction.One hundred and sixty-six Australian psychologists completed an online survey measuring self-efficacy, technology affinity and telehealth satisfaction.Self-efficacy mediated 54% of the relationship between telehealth affinity and telehealth satisfaction. Self-rated intervention skills, assessment and measurement skills, and positive attitude towards technology contributed to telehealth satisfaction.The integration of self-efficacy components into traditional telehealth training for psychologists is explored. Increased self-efficacy may lead to greater telehealth satisfaction, potentially contributing to better treatment outcomes for clients.
What is already known about this topic: Clients often rate their experience of telehealth positively, but less is knows about the experience of clinicians, and in particular psychologists.Overall satisfaction with the telehealth experience and general technology skills (technology affinity) have been shown to influence the adoption of telehealth by clinicians. Self-efficacy has been shown to positively influence attitudes to telehealth.Telehealth skills, clinician satisfaction and clinician self-efficacy may also influence client outcomes.Clients often rate their experience of telehealth positively, but less is knows about the experience of clinicians, and in particular psychologists.Overall satisfaction with the telehealth experience and general technology skills (technology affinity) have been shown to influence the adoption of telehealth by clinicians.

Bacterial spot disease of cucurbits, caused by Xanthomonas cucurbitae, is a major problem in cucurbit‐growing areas worldwide. In the Midwestern region of the United States, pumpkin and squash fields can have greater than 90% infected fruits, leading to high yield losses. While reference genomes are available for this bacterial species, the genetic diversity between different strains and populations is unknown. After performing restriction‐site associated DNA sequencing (RAD‐seq) analysis of X. cucurbitae isolates collected from the Midwestern region, we selected five representative isolates for further characterization, which included whole‐genome sequencing and in vitro enzyme and in planta virulence assays. Our results suggest that minimal genetic diversity exists between these isolates, and that the isolates have differential virulence on different cucurbit host plants. This study contributes to our understanding of X. cucurbitae population dynamics in the Midwestern region and may assist with developing additional management strategies for controlling bacterial spot disease of cucurbits.

Field education is the most challenging aspect of social work education and there are unprecedented challenges currently measuring good practice with quality outcomes. Thus, it's important to have competency-based key performance indicators (KPIs) to assess social work professional practice. This study is a national, mixed-methods Delphi research study with three rounds. Round 1 required participants (N=46) to provide open-text qualitative responses on how to assess students' competency on placement, meeting core social work values and ethics. In round 2, participants' responses (N=59) were analyzed in relation to AASW Practice Standards. The final round, consensus was obtained from participants (N=71) with 31 KPIs receiving participant agreement. Establishing national agreed-on KPIs is an essential step in maintaining consistency across diverse placement sites. [ABSTRACT FROM AUTHOR]

Whilst some research has been conducted into those who engage in non-consensual condom removal, the aim of the study was to explore the relationship between Dark Triad of Personality traits (i.e. machiavellianism, narcissism, psychopathy) and arousal from, intention to engage in, and reported behavioural history of non-consensual condom removal (i.e. stealthing), which is a type of sexual violence. Results found that there were associations between all Dark Triad traits and all types of condom use resistance; individuals who were aroused by stealthing scenarios and who reported a behavioural history of stealthing scored significantly higher on machiavellianism, narcissism and psychopathy compared to those who were not aroused by or did not report a behavioural history of stealthing. Psychopathy and narcissism were found to be significant predictors of a person's reported intention to engage in stealthing behaviour. Future research into the relationship between Dark Triad and other types of personality traits and stealthing behaviour is needed to inform assessment, prevention, and treatment for perpetrators of this type of sexual violence.

Young carers in Australia are people aged under 25 who undertake a substantial familial caring role. A range of associated disadvantages with this practice have been identified, however, no systematic literature review currently exists to consolidate the Australian research. Articles were included if they used a broadly quantitative methodology, were in English, and published since 2002 using original, contemporary Australian data and specifically discussed the caring role. The following databases were searched: Psychology and Behavioral Sciences Collection, APA PsychInfo, APA PsycArticles, MEDLINE Complete, Academic Search Complete, CINAHL with Full Text, Child Development & Adolescent Studies, APA PsycTherapy. Fourteen articles were included, and synthesised using a narrative style, capturing detailed information on approximately 8000 young carers, and briefer census-style data on 128,000 young carers. Quality ratings and risk of bias analyses were included. It was found that young carers exhibit a range of disadvantages across academic, social, and mental health domains, particularly when the care recipient is a parent, and even more so if the care needs are related to mental health or substance use. Additional research is required to further explore the relationships between the young caring role and outcomes. [ABSTRACT FROM AUTHOR]

Quantitative Biology - Neurons and Cognition - Abstract
Conscious experience is awash with underlying relationships. Moreover, for various brain regions such as the visual cortex, the system is biased toward some states. Representing this bias using a probability distribution shows that the system can define expected quantities. The mathematical theory in the present paper links these facts by using expected float entropy (efe), which is a measure of the expected amount of information needed, to specify the state of the system, beyond what is already known about the system from relationships that appear as parameters. Under the requirement that the relationship parameters minimise efe, the brain defines relationships. It is proposed that when a brain state is interpreted in the context of these relationships the brain state acquires meaning in the form of the relational content of the associated experience. For a given set, the theory represents relationships using weighted relations which assign continuous weights, from 0 to 1, to the elements of the Cartesian product of that set. The relationship parameters include weighted relations on the nodes of the system and on their set of states. Examples obtained using Monte-Carlo methods (where relationship parameters are chosen uniformly at random) suggest that efe distributions with long left tails are most important., Comment: 33 pages (double spacing), 11 figures, 15 Tables

Jamieson, Daniel and Mason, Jonathan
- Abstract
People with an Intellectual Disability (ID) are around 4 times more likely to suffer with a mental health disorder than IQ-typical people, however previous studies have shown they may be less likely to be diagnosed. One suggested cause of this is the diagnostic overshadowing bias: the tendency for practitioners to attribute unusual behaviour, thoughts or feelings to a person's ID and not a separate mental health disorder.In the current study N = 87 participants were randomly assigned 1 of 2 clinical vignettes describing a client who is displaying symptoms of mental health disorder. Vignette 1 described a client with an IQ of 105 who graduated from high school. Vignette 2 described a client with an IQ of 55 who attended special classes throughout school. All other details were identical. Participants then rated the likelihood of 7 diagnoses on a 5-point Likert scale.Contrary to our hypothesis participants were not less likely to diagnose a mental health disorder in people with an ID and this was found to exist across all profession types involved in the study.Although these findings indicate that the diagnostic overshadowing bias may not be present in Australia, several factors including a reported lack of confidence in working with clients with an ID suggest the inclusion of ID specific training may be beneficial.

The theoretical base for consciousness, in particular an explanation of how consciousness is defined by the brain, has long been sought by science. We propose a partial theory of consciousness as relations defined by typical data. The theory is based on the idea that a brain state on its own is almost meaningless but in the context of the typical brain states, defined by the brain's structure, a particular brain state is highly structured by relations. The proposed theory can be applied and tested both theoretically and experimentally. Precisely how typical data determines relations is fully established using discrete mathematics., Comment: 16 pages, 8 figures, First submitted for publication March 2012

UNIFORM algebras have been extensively investigated because of their importance in the theory of uniform approximation and as examples of complex Banach algebras. An interesting question is whether analogous algebras exist when a complete valued field other than the complex numbers is used as the underlying field of the algebra. In the Archimedean setting, this generalisation is given by the theory of real function algebras introduced by S. H. Kulkarni and B. V. Limaye in the 1980s. This thesis establishes a broader theory accommodating any complete valued field as the underlying field by involving Galois automorphisms and using non-Archimedean analysis. The approach taken keeps close to the original definitions from the Archimedean setting. Basic function algebras are defined and generalise real function algebras to all complete valued fields. Several examples are provided. Each basic function algebra is shown to have a lattice of basic extensions related to the field structure. In the non-Archimedean setting it is shown that certain basic function algebras have residue algebras that are also basic function algebras. A representation theorem is established. Commutative unital Banach F-algebras with square preserving norm and finite basic dimension are shown to be isometrically F-isomorphic to some subalgebra of a Basic function algebra. The theory of non-commutative real function algebras was established by K. Jarosz in 2008. The possibility of their generalisation to the non-Archimedean setting is established in this thesis. In the context of complex uniform algebras, a new proof is given using transfinite induction of the Feinstein-Heath Swiss cheese "Classicalisation" theorem., Comment: PhD Thesis 2012, 113 pages, The main results were presented at The Sixth Conference on Function Spaces at SIUE USA 2010

Mathematics - Functional Analysis ,46J10 (Primary) 54H99 (Secondary) - Abstract
A theory of allocation maps has been developed by J. F. Feinstein and M. J. Heath in order to prove a theorem, using Zorn's lemma, concerning the compact plane sets known as Swiss cheese sets. These sets are important since, as domains, they provide a good source of examples in the theory of uniform algebras and rational approximation. In this paper we take a more direct approach when proving their theorem by using transfinite induction and cardinality. An explicit reference to a theory of allocation maps is no longer required. Instead we find that the repeated application of a single operation developed from the final step of the proof by Feinstein and Heath is enough., Comment: 10 pages, 1 figure, Accepted for publication by the Proceedings of the American Mathematical Society, volume 138, year 2010, number 12, pages 4423-4432

This research explores the use of simulation technology in supporting and preparing social work students (n = 336) for core professional skills needed for practice. This study utilized a randomized experimental design using a 3 × 3 between-subjects design to assess the impact of the type of simulation (e.g. traditional written case studies, video-based simulations, and live actor simulations) and type of scenario (e.g. family/domestic violence, suicide/mental health and hospital/medical) on social work student's ability to undertake a psychosocial assessment. Results showed that students developed more comprehensive psychosocial assessments when presented with video simulations compared to traditional methods, using actors or written case studies. This research builds evidence for social work to embrace the use of simulation to develop these skills for students in a practice setting that removes not only the fear of doing harm but also the real possibility of harm in complex scenarios. Social work field education is under increasing pressure to meet professional standards, especially with the impact of the COVID pandemic. Thus, the profession must consider alternatives for training students including utilizing technology. While many other professional disciplines incorporated the use of simulation in training, social work has been slow to embrace this trend while favoring traditional teaching methods.

During the Arizona Winter School 2008 (held in Tucson, AZ) we worked on the following problems: a) (Expanding a remark by S. Lang). Define $E_0 = \overline{\mathbb{Q}}$ Inductively, for $n \geq 1$, define $E_n$ as the algebraic closure of the field generated over $E_{n-1}$ by the numbers $\exp(x)=e^x$, where $x$ ranges over $E_{n-1}$. Let $E$ be the union of $E_n$, $n \geq 0$. Show that Schanuel's Conjecture implies that the numbers $\pi, \log \pi, \log \log \pi, \log \log \log \pi, \ldots $ are algebraically independent over $E$. b) Try to get a (conjectural) generalization involving the field $L$ defined as follows. Define $L_0 = \overline{\mathbb{Q}}$. Inductively, for $n \geq 1$, define $L_n$ as the algebraic closure of the field generated over $L_{n-1}$ by the numbers $y$, where $y$ ranges over the set of complex numbers such that $e^y\in L_{n-1}$. Let $L$ be the union of $L_n$, $n \geq 0$. We were able to prove that Schanuel's Conjecture implies $E$ and $L$ are linearly disjoint over $\overline{\mathbb{Q}}$., Comment: 8 pages summarizing the results obtained in this project during the AWS08 http://swc.math.arizona.edu/aws/08/08WaldschmidtOutline.pdf

Art and industrial design share a long history, with some of the first industrial designers originating from the arts. Through the early part of the twentieth century many designers were educated and influenced by artists and on occasions they collaborated in the development of art/design movements. In recent decades this relationship has weakened with artists and industrial designers working towards different goals and paying less attention to how one another work. This research was undertaken to investigate whether contemporary artists were now using methods that may facilitate industrial design.

- Abstract
This technology needs assessment report of populations living in the Southeast Los Angeles (SELA) region addresses the root causes and dilemmas of the “digital divide” problem. This study addresses the central question: how can the Southeast Cities Technology Collaborative (SCTC) structure a regional intervention project that spearheads development in the productive use of information technology and benefits a low-income population with low educational attainment in Southeast Los Angeles (SELA) cities?The study first provides a regional survey of the fiscal, institutional, and technological challenges facing this demographic region. The SELA region is a sub-section of Los Angeles County and comprised of eight cities and one unincorporated district: Bell, Bell Gardens, Cudahy, Huntington Park, Maywood, South Gate, Vernon, Walnut Park, and the Florence-Firestone area. The demographic survey identifies that the SELA region has strong indicators of digital divide inequality.The study further provides an assessment of existing digital divide intervention efforts in the SELA region: public access to computers and the internet at public schools, public libraries, nonprofit and community-based organization, city-initiated programs, and private for-profit services. The study takes account of community impressions and provides specific recommendations for institutional changes than can better integrate the population into a positive development process.The study finds that investment in coordinating the integration of human capacity and technical infrastructure to network social service providers and users will support the social and economic advancement of the region. Investment in training school-age children, youth, and adults to harness the productive uses of information and telecommunications technology will yield the greatest benefits for future generations.

Sustainability is a serious concern for future transportation planning, but it should not be regarded as a straightforward problem with a simple but difficult solution. Achieving sustainability is a contextual and multi- dimensional process. Just as transportation pollutes the environment in a variety of ways and over a long period of time, addressing these pollut- ants requires a long-term, incremental, and multi-dimensional strategy to achieve sustainability. Genuine sustainability will likely take generations to achieve, but such a goal is most likely to be achieved through steady, incremental understanding and improvements in environmental impact. Given that sustainability is a long-term agenda, history is a useful and essential guide.

616.89 - Abstract
People with learning disabilities are known to be at increased risk of developing mental health problems. The reasons for this vulnerability are unclear, and a range of biological, sociocultural, cognitive, systemic and psychodynamic explanations have been forwarded. Further, although a significant amount of research has been focussed on psychological therapies for mental health problems, until recently little attention has been given to their application to people with learning disabilities. This, in combination with a number of other factors (such as a historical trend to suppose that people with learning disabilities struggle to make use of psychological therapy), means that this client group has relatively little access to therapy services. Five factors were proposed to affect the provision of psychological therapy to people with learning disabilities: service resources, the perceived effectiveness of psychological therapy with this client group, the perceived individual competence of clinicians in administering psychological therapy to this client group, the level of the client's disability and the diagnostic overshadowing bias. Psychologists and psychiatrists working in learning disability services throughout the UK were sent a questionnaire examining the 5 factors proposed above. 133 psychologists and 90 psychiatrists (32% response rate) returned completed questionnaires. Perceived individual competence was found to be the most consistent predictor of the provision of psychological therapy to people with learning disabilities. Service resources and effectiveness emerged as important in the case of systemic therapy and psychodynamic therapy, although only marginally so. Clinicians appeared to consider psychological therapy less appropriate, harder to do and less effective as the level of the client's disability increased. In addition, diagnostic overshadowing appeared to be influencing the way in which clinicians appraised the symptoms of mental health problems in people with learning disabilities. The significance of these findings is discussed in light of both recent clinical research and current developments in healthcare policy for people with learning disabilities.

50. The Ties that Bind: Infrastructure as the Defining Role of Planning

planning ,transportation ,planning ,transportation - Abstract
Practitioners and theorists have long searched for a clear definition of the role of planning. The attention to the subject is not surprising since a clear role lends any profession’s sense of identity, integrity, and legitimacy. Wildavsky (1973) criticized the planning profession’s lack of clarity in this regard, implying that the profession was attempting to encompass too much. He suggested that if “planning is everything, maybe it is nothing.” This view exemplifies a debate common to many disciplines over what constitutes core theory and practice.However, such debates are particularly important for inter-disciplinary professions such as planning. This essay argues that, for the planning profession, infrastructure is the organizational backbone around which basic principles, technical methods, professional norms, and even research are expressed. Interpreting its meaning liberally, infrastructure defines the very nature of planning. In turn, infrastructure requires planning, perhaps now more than ever. This symbiotic relationship between planning and infrastructure is unique and helps provide a clarity and focus that allow the profession to be sufficiently comprehensive without losing its meaning and purpose.
