P.I.C.U., H.D.U., A.O.A. What treatment do we provide?: Current descriptions of the function of intensive care for inpatient Psychiatric Health Care.

Purpose – This paper adds to growing research of psychiatric intensive care units (PICU) by recounting descriptions of psychiatric intensive care settings and discusses the perceptions held by nurses of the organisational interfaces, arrangements and provisions of care in these settings. Design/methodology/approach – Data gathered from focus groups held with nurses from two PICUs was used to establish terminology, defining attributes, related concepts, antecedents, values, processes and concepts related to current practices. A literature search was conducted to permit a review of the conceptual arrangements and contemporary understanding of intensive care for people experiencing acute psychiatric illness based on the perspectives held by the nurses from the focus groups. Findings – Dissonance between service needs and the needs and management of individual patients overshadow strategies to implement comprehensive recovery-oriented approaches. Three factors are reported in this paper that influence standards and procedural practice in PICU; organisational structures; physical structures; and subtype nomenclature. Practical implications – Acute inpatient care is an important part of a comprehensive approach to mental health services. Commonly intensive acute care is delivered in specialised wards or units co-located with acute mental health inpatient units mostly known as PICU. Evidence of the most effective treatment and approaches in intensive care settings that support comprehensive recovery for improved outcomes is nascent. Originality/value – Current descriptions from nurses substantiate wide variations in the provisions, design and classifications of psychiatric intensive care. Idiosyncratic and localised conceptions of psychiatric intensive care are not adequately entailing effective treatment and methods in support of recovery principles for improved and comprehensive outcomes. The authors suggest that more concrete descriptions, guidelines, training and policies for provision of intensive psychiatric health care encompassing the perspective of nursing professionals, would reinforce conceptual construction and thus optimum treatments within a comprehensive, recovery-oriented approach to mental health services.

We still don’t know how much BPMN is enough – but we are getting closer

Process models expressed in BPMN typically rely on a small subset of all available symbols. In our 2008 study, we examined the composition of these subsets, and found that the distribution of BPMN symbols in practice closely resembles the frequency distribution of words in natural language. We offered some suggestions based on our findings, how to make the use of BPMN more manageable and also outlined ideas for further development of BPMN. Since this paper was published it has provoked spirited debate in the BPM practitioner community, prompted the definition of a modeling standard in US government, and helped shape the next generation of the BPMN standard.

Are we missing opportunities? Understanding health behaviours associated with overweight in pregnancy

While maternal obesity, excess pregnancy weight gain and lifestyle behaviours are associated with future overweight for both mothers and babies, there is limited research on how best to intervene. An evidence base that identifies behavioural influences is crucial to the development of effective interventions. This thesis aims to gain an understanding of maternal behavioural outcomes of healthy eating, physical activity and gestational weight gain (GWG), the psychosocial influences on these and to examine differences according to pre-pregnancy weight status. The New Beginnings Healthy Mothers and Babies Study was a prospective observational study using the PRECEDE-PROCEED model of health promotion planning as a framework. A consecutive sample of 715 women was recruited. Height and weight were measured and women completed questionnaires at approximately 16 and 36 weeks gestation. This thesis presents three chapters of original research across four study domains. While healthy eating was widely regarded as important during pregnancy and had become more so, there was more variability in attitudes towards physical activity. Ninety-two percent of participants achieved the maximum knowledge score relating to the influence of nutrition on pregnancy. However, 8% and 36% respectively knew how many serves of fruit and vegetables should be consumed daily. Six percent of participants met the recommendations for fruit consumption, 4% achieved the recommended vegetable intake and 44% achieved sufficient physical activity. There were few differences between healthy and overweight women for measures of physical activity and healthy eating. Many predisposing, reinforcing and enabling factors with a positive influence on health behaviours were lower in women commencing pregnancy overweight and those factors with a negative influence on health behaviours were higher when compared to healthy weight women. Some of these antecedents to health behaviours that were different according to prepregnancy weight status were associated with diet quality and physical activity. While self efficacy was consistently associated with diet quality and physical activity for both weight groups, other associations between specific predisposing, reinforcing and enabling factors differed with behaviour and weight status group. These results highlight the complexity of supporting behaviour change in a one-size-fits-all approach. Sixty-four percent of participants gained weight outside of recommendations. Compared to healthy weight women, those women who were already overweight at the beginning of pregnancy were more likely to gain too much weight (30% vs 56%, p<0.001). Only 35% of participants reported their correct recommended weight gain. Excess GWG was associated with few predisposing factors, however, these were not consistent between prepregnancy weight status groups. Less than 50% of women reported sometimes/usually/always receiving advice from health professionals relating to healthy eating, physical activity or GWG. These results indicate that there are opportunities to improve the advice and support provided by health care professionals in the antenatal period. Evidence from this PhD research suggests that there is a need for effective prevention and management of excess weight in pregnancy. Effective management of this problem is likely to require a multidisciplinary approach with multi-level strategies. Importantly, the strategies may need to be tailored according to pre-pregnancy weight status. Collectively, the evidence derived from this thesis suggests that opportunities to support healthy lifestyles and prevent future overweight are being missed during pregnancy.

Impact induced chemisorption of C20 isomers on diamond (001)–(2×1) surface

The adsorption of low-energy C20 isomers on diamond (0 0 1)–(2×1) surface was investigated by molecular dynamics simulation using the Brenner potential. The energy dependence of chemisorption characteristic was studied. We found that there existed an energy threshold for chemisorption of C20 to occur. Between 10 and 20 eV, the C20 fullerene has high probability of chemisorption and the adsorbed cage retains its original structure, which supports the experimental observations of memory effects. However, the structures of the adsorbed bowl and ring C20 were different from their original ones. In this case, the local order in cluster-assembled films would be different from the free clusters.

Teaching reading comprehension across the national curriculum with EAL/D learners : are we brave enough to really take it on?

Teaching English to EAL/D learners as a cross-curricula priority, not just the purview of the English classroom or language specialist, is now officially endorsed in the national curriculum. Yet many teachers, including subject English teachers, feel ill-equipped for this task. This paper presents an action research project conducted with a teacher of junior secondary English and Geography. The focus of the project was developing metacognitive reading strategies among EAL/D learners to enable them to access content area information more effectively and more independently. We discuss the particular strategies that were beneficial for students at the Emerging level of English and present a range of research-based reading strategies that teachers can embed in regular teaching in order to enhance reading comprehension. Examples from Geography and English lessons will be provided to show how the teaching of explicit ‘second language’ reading strategies can position EAL/D learners as valuable members of the classroom.

“Freer than we Feel” : Applying the Critical Dimension of Consciousness to Children’s Multimodal Encoding

Reports of children and teachers taking transformative social action in schools are becoming rare. This session illustrates how teachers, while feeling the weight of accountability testing in schools, are active agents who can re-imagine literacy pedagogy to change elements of their community. It reports the critical dimensions of a movie-making unit with Year 5 students within a school reform project. The students filmed interviews with people in the local shops to gather lay-knowledge and experiences of the community. The short documentaries challenged stereotypes about what it is like to live in Logan, and critically identified potential improvements to public spaces in the local community. A student panel presented these multimodal texts at a national conference of social activists and community leaders. The report does not valorize or privilege local or lay knowledge over dominant knowledge, but argues that prescribed curriculum should not hinder the capacity for critical consciousness.

Trauma education in Australia : where are we in 2006?

This presentation describes the available trauma education programs, both formal and informal, that are currently being provided in Australia.

We need to talk about … economics

I want to take up the “economies” part of this conference's theme, “Materialities: Economies, Empiricism and Things,” and engage with those critics of the creative industries position within media, cultural and communication studies. There's certainly been a bit of (symbolic) attempted patricide on the creative industries side, but there has been an even stronger disavowal of parentage, even a bit of—always symbolic—attempted infanticide, on the other...

Social media metrics : are we measuring business value?

Over the past few years many organizations that directly or indirectly interact with consumers have invested heavily into a social media presence. As a consequence some success indicators are openly available to users of many social media platforms, such as the number of fans (or followers, members, visitors and others) or the amount of content(tweets, images, shares or other content). Many organizations additionally track their social activities internally to understand audience reach, consumer influence, brand image, consumer preference or other key metrics that make sense for a business. However, most of the immediately available social media success metrics are activity-based and many organizations are struggling with establishing a direct relationship to business success. This paper systematically reviews some of the common social media metrics/ratings used by organisations, critically analyse its business value and identify gaps formulating research questions for empirical study and concluding with recommendations and suggestions for future research.

‘We don’t leave our identities at the city limits’ : Aboriginal and Torres Strait Islander people living in urban localities

Aboriginal and Torres Strait Islander people who live in cities and towns are often thought of as ‘less Indigenous’ than those who live ‘in the bush’, as though they were ‘fake’ Aboriginal people — while ‘real’ Aboriginal people live ‘on communities’ and ‘real’ Torres Strait Islander people live ‘on islands’. Yet more than 70 percent of Australia’s Indigenous peoples live in urban locations (ABS 2007), and urban living is just as much part of a reality for Aboriginal and Torres Strait Islander people as living in remote discrete communities. This paper examines the contradictions and struggles that Aboriginal and Torres Strait Islander people experience when living in urban environments. It looks at the symbols of place and space on display in the Australian cities of Melbourne and Brisbane to demonstrate how prevailing social, political and economic values are displayed. Symbols of place and space are never neutral, and this paper argues that they can either marginalise and oppress urban Aboriginal and Torres Strait Islander people, or demonstrate that they are included and engaged.

“We eat more than kangaroo tail or dugong you know…” : recent indigenous Australian cookbooks

This paper focuses on a series of cookbooks published by Indigenous Australian groups. These cookbooks are typically produced with government funding, and are developed by nutritionists, dieticians, and health workers in consultation with local communities. They are designed to teach Indigenous Australians to cook healthy, nutritious, low-cost meals. In this paper, Fredericks and Anderson identify the value of these cookbooks as low-cost, public health interventions. However, they note that their value as health interventions has not been tested. Fredericks and Anderson question the value of these cookbooks within the broader context of the health disadvantage faced by Indigenous Australians. They argue that the cookbooks are developed from a Western perspective of health and nutrition that fails to recognise the value of traditional Indigenous foodways. They suggest that incorporating more Indigenous food knowledge and food-related traditions into cookbooks may be one way of improving health among Indigenous peoples and revitalising Indigenous knowledge.

Quantum one-time programs

A one-time program is a hypothetical device by which a user may evaluate a circuit on exactly one input of his choice, before the device self-destructs. One-time programs cannot be achieved by software alone, as any software can be copied and re-run. However, it is known that every circuit can be compiled into a one-time program using a very basic hypothetical hardware device called a one-time memory. At first glance it may seem that quantum information, which cannot be copied, might also allow for one-time programs. But it is not hard to see that this intuition is false: one-time programs for classical or quantum circuits based solely on quantum information do not exist, even with computational assumptions. This observation raises the question, "what assumptions are required to achieve one-time programs for quantum circuits?" Our main result is that any quantum circuit can be compiled into a one-time program assuming only the same basic one-time memory devices used for classical circuits. Moreover, these quantum one-time programs achieve statistical universal composability (UC-security) against any malicious user. Our construction employs methods for computation on authenticated quantum data, and we present a new quantum authentication scheme called the trap scheme for this purpose. As a corollary, we establish UC-security of a recent protocol for delegated quantum computation.

Are we there yet? Early years reform in Queensland : stakeholder perspectives on the introduction of funded preschool programs in long day care services

Australian educators are currently engaging with wide-ranging, national early childhood reform that is reshaping early childhood education and care. The Australian reform agenda reflects many of the early childhood policy directions championed by bodies such as the Organisation for Economic Cooperation and Development and the United Nations Children's Education Fund, and is based on the dual discourse of (i) starting strong and (ii) investing in the early years. However, despite its traction in policy rhetoric and policy there is little empirical evidence of how reform is being played out. This paper reports on research undertaken in collaboration with the Queensland Office for Early Childhood Education and Care to generate sector feedback on one element of the reform agenda, the implementation of universal preschool in Queensland. The study aimed to determine the efficacy of the new policy in supporting the provision of 'approved preschool programs' within long day care services. Drawing together the views and experiences of a range of stakeholders, including peak organisations, service providers, directors, preschool teachers and government policy officers, it provides a situated case study of the implementation of universal preschool, and offers empirical evidence of how this policy is being played out at the local level. The paper identifies the opportunities and challenges in implementing universal preschool in Queensland that may have bearing on early childhood reform in Australia as well as other countries. Discussion of key findings is set within an overview of the ECEC policy agenda in Australia, with a particular focus on the commitment to universal preschool. Les éducateurs australiens s’engagent présentement dans une vaste réforme nationale de la petite enfance qui remodèle l'éducation et l’accueil de la petite enfance. Le programme de la réforme australienne reflète plusieurs des orientations en politique de la petite enfance soutenues par des organismes comme l'Organisation de coopération et de développement économiques (OCDE) et le Fonds des Nations Unies pour les enfants (UNICEF). Il s’appuie sur le double discours de (i) un bon départ et de (ii) l’investissement dans les premières années. Cependant, en dépit de son attrait en rhétorique de politique et en politique il y a peu de données empiriques sur la façon dont la réforme se déroule. Cet article rend compte de la recherche entreprise en collaboration avec le bureau de l'éducation et l’accueil à la petite enfance du Queensland afin d’obtenir une rétroaction du secteur sur un élément de la réforme, la mise sur pied du préscolaire universel dans le Queensland. L'étude visait à déterminer l'efficacité de la nouvelle politique pour soutenir la disposition «programmes préscolaires approuvés» dans les services de garde à temps plein. En regroupant les perspectives et les expériences d'une gamme d’intervenants, y compris d’importantes organisations, des prestataires de service, des directeurs, des enseignants du préscolaire et des fonctionnaires de politique gouvernementale, elle constitue une étude de cas localisée de l'exécution la mise sur pied du préscolaire universel, et fournit des données empiriques sur la façon dont cette politique se met en place au niveau local. L’article identifie les opportunités et les défis liés à l’implantation du préscolaire universel au Queensland, qui pourraient avoir une portée sur la réforme de petite enfance en Australie ainsi que dans d'autres pays. La discussion des principaux résultats est faite en lien avec un aperçu global de la politique d'éducation et d’accueil de la petite enfance en Australie, avec un accent particulier sur l'engagement envers le préscolaire universel. Los educadores australianos actualmente están involucrados en una amplia reforma de la educación temprana nacional que está revolucionando la educación preescolar y los servicios de cuidado. El programa de reforma Australiana refleja muchas de las direcciones políticas relacionadas con la infancia temprana incitadas por organismos como la Organización de Cooperación y Desarrollo Económicos y el Fondo Educacional Infantil de las Naciones Unidas, y se basa en el doble discurso de (i) empezando fuertemente e (ii) invertir en los primeros años. Sin embargo, a pesar de su política de tracción en retórica y política, hay pocos datos empíricos de cómo la reforma se está llevando a cabo. Este documento informa sobre las investigaciones llevadas a cabo en colaboración con la Oficina de Queensland de Educación tempana y cuidados, para generar comentarios del sector, sobre uno de los elementos de la agenda de reforma, la aplicación del preescolar universal en Queensland. El estudio tiene como objetivo determinar la eficacia de la nueva política para apoyar la prestación de "programas preescolares aprovados" dentro se los servicios de guardería y cuidado. Reuniendo los puntos de vista y las experiencias de una serie de interesados, entre ellos algunas organizaciones cumbre, proveedores de servicios, los directores, los maestros preescolares y oficiales de política y gobierno, se logra un estudio simulado de la implementación del preescolar universal, y ofrece evidencia empírica de cómo esta política se está llevando a cabo en el plano local. El documento identifica las oportunidades y desafíos en la implementación del preescolar universal en Queensland, que puede repercutir en la reforma de la indancia temprana en Australia, así como en otros países. La discusión de los resultados claves se encuentra en el interior de una visión de la agenda política de ECEC en Australia, con un enfoque particular en el compromiso con el preescolar universal.

The search for migraine genes : an overview of current knowledge

Migraine is a complex familial condition that imparts a significant burden on society. There is evidence for a role of genetic factors in migraine, and elucidating the genetic basis of this disabling condition remains the focus of much research. In this review we discuss results of genetic studies to date, from the discovery of the role of neural ion channel gene mutations in familial hemiplegic migraine (FHM) to linkage analyses and candidate gene studies in the more common forms of migraine. The success of FHM regarding discovery of genetic defects associated with the disorder remains elusive in common migraine, and causative genes have not yet been identified. Thus we suggest additional approaches for analysing the genetic basis of this disorder. The continuing search for migraine genes may aid in a greater understanding of the mechanisms that underlie the disorder and potentially lead to significant diagnostic and therapeutic applications.
