Ethnography of housing

This paper is the final report of a research project spanning three years, exploring three field locations and capturing the stories of forty (plus) housing workers. Using an ethnographic research approach, this paper provides an account of how housing workers use language and stories to make sense of their challenging and changing work. First hand accounts ('stories') about everyday housing work frame the data in this paper, explaining how housing workers in Victoria have experienced and made sense of the shift from public housing as 'affordable housing for the working poor' to 'housing of last resort for the most vulnerable and needy members of the community'. Using a number of composite stories, this paper provides the reader with a glimpse into the work of public housing staff, transporting the reader from the relativley static world of policy and procedure to the more colourful world of tenants with ' high and complex' needs, 'wicked' problems, weary staff and the daily reality of organisational change.

A unique feature of this research is the comparison of how different workers use their stories to build a range of 'socially constructed realities' around the housing work and its wicked problems. With a few exceptions (Saugeres, 1999, Howe, 1998, Clapham et al., 2000, Darcy, 1999) the voices of frontline staff are largley absent from contemporary housing literature. In this paper, I use the stories of frontline staff to build a comparative case study of the socially constructed realities for frontline staff and the corresponding realities of the managers at head office (and vice versa). This 'same problem, different perspective' approach allows the reader to better understand how the same problem is understood and approached in different ways, depending on the individual's organisational role, responsibility and authority. Using stories about 'working with problem tenants', 'collecting rental arrears from the poor and marginalised', maintaining old, neglected properties' and 'coping with organisational change', this paper illustrates how the shifting (and sometimes contradictory) construction of housing problems has meant that the organisation has long struggled to devise and implement sustainable remedies to these problems.

The following pages describe how the problem identified in the Housing Office Review (and experienced in the daily work of the 'modern day' housing worker) are simply a contemporary manifestation of  'age old public housing issues'. This paper describes and explains how housing staff have long used narrative to make sense of their often difficult work and ultimately, how they understand and experience a major process of operational policy change associated with the shift from 'public' housing to 'welfare' housing.

Driver behaviour prediction for motion simulators using changepoint segmentation

Driving phenomenon is a repetitive process, that permits sequential learning under identifying the proper change periods. Sequential filtering is widely used for tracking and prediction of state dynamics. However, it suffers at abrupt changes, which cause sudden incremental prediction error. We provide a sequential filtering approach using online Bayesian detection of change points to decrease prediction error generally, and specifically at abrupt changes. The approach learns from optimally detected segments for identifying driving behaviour. Change points detection is done by the Pruned Exact Linear Time algorithm. Computational cost of our approach is bounded by the cost of the implemented sequential filter. This computational performance is suitable to the online nature of motion simulator's delay reduction. The approach was tested on a simulated driving scenario using Vortex by CM Labs. The state dimensions are simulated 2D space coordinates, and velocity. Particle filter was used for online sequential filtering. Prediction results show that change-point detection improves the quality of state estimation compared to traditional sequential filters, and is more suitable for predicting behavioural activities.

Proximate cues to phases of movement in a highly dispersive waterfowl, anas superciliosa

BACKGROUND: Waterfowl can exploit distant ephemeral wetlands in arid environments and provide valuable insights into the response of birds to rapid environmental change, and behavioural flexibility of avian movements. Currently much of our understanding of behavioural flexibility of avian movement comes from studies of migration in seasonally predictable biomes in the northern hemisphere. We used GPS transmitters to track 20 Pacific black duck (Anas superciliosa) in arid central Australia. We exploited La Niña conditions that brought extensive flooding, so allowing a rare opportunity to investigate how weather and other environmental factors predict initiation of long distance movement toward freshly flooded habitats. We employed behavioural change point analysis to identify three phases of movement: sedentary, exploratory and long distance oriented movement. We then used random forest models to determine the ability of meteorological and remote sensed landscape variables to predict initiation of these phases. RESULTS: We found that initiation of exploratory movement phases is influenced by fluctuations in local weather conditions and accumulated rainfall in the landscape. Initiation of long distance movement phases was found to be highly individualistic with minor influence from local weather conditions. CONCLUSIONS: Our study reveals how individuals utilise local conditions to respond to changes in resource distribution at broad scales. Our findings suggest that individual movement decisions of dispersive birds are informed by the integration of multiple weather cues operating at different temporal and spatial scales.

Decadal decline in demersal fish biomass coincident with a prolonged drought and the introduction of an exotic starfish

Between 1990 and 2011, Port Phillip Bay in southern Australia experienced 2 major ecological disturbances: a prolonged drought from 1997 to 2010, and the introduction of the invasive starfish, Asterias amurensis. The drought reduced land-based nitrogen inputs by 64%, and the biomass of A. amurensis in the deep centre of the bay peaked at 56% of the resident fish biomass in 2000. The impacts of these disturbances on fish were assessed using a demersal trawl time-series spanning 2 decades (1990 to 2011). The timing and spatial extent of changes to fish biomass were analysed using ANCOVA and change point analysis. During the drought, fish biomass declined by 69% in the deep centre of the bay, by 50% at intermediate depths, and showed no significant change around the shallow fringes. This spatial pattern is consistent with hydrodynamic modelling, which suggests that during the drought a greater proportion of the (lower) nitrogen input was retained near the coastal fringe. Most of the decline in fish biomass was attributed to the cumulative effects of reduced productivity during the 12 yr drought. However, declines in 3 species in the deep region were attributed to competition with A. amurensis. Each of these species exhibited high dietary overlap with A. amurensis and displayed sharp declines in biomass coinciding with the peak abundance of A. amurensis in 2000.

Assessing offender readiness to change problems with anger

It is widely acknowledged that offender rehabilitation outcomes can be improved by attending to responsivity issues, including the readiness and motivation of offenders to undertake and engage in treatment. The measurement of responsivity, readiness and motivation in offenders, however, has received relatively little research attention. In this paper we focus on anger management programmes and evaluate the utility and psychometric properties of a measure of stages of change in relation to changing anger - the Anger Readiness to Change Questionnaire (ARCQ). Using data from a large sample of offenders undergoing anger management interventions, we investigated the construct validity, convergent validity and predictive validity of the ARCQ. We conclude the ARCQ may have utility as a measure for selecting offenders who are suitable for anger management interventions.

Investing in intelligence : an inquiry into educational paradigm change

In this philosophical and practical-critical inquiry, I address two significant and closely related problems - whether and how those involved in the enterprise of education conceptualise a need for educational change, and the observed resistance of school cultures to change efforts. I address the apparent lack of a clear, coherent and viable theory of learning, agency and change, capable of making explicit the need, substantive nature and means of educational change. Based on a meta-analysis of numerous theories and perspectives on human knowing, learning, intelligence, agency and change, I synthesise a 'Dynamic Paradigm of Learning and Change', characterised by fifteen Constructs. I argue that this more viable Paradigm is capable of informing both design and critique of systemic curriculum and assessment policies, school organisation and planning models, professional learning and pedagogical practice, and student learning and action. The Dynamic Paradigm of Learning and Change contrasts with the assumptions reflected in the prevailing culture of institutionalised education, and I argue that dominant views of knowledge and human agency are both theoretically and practically non-viable and unsustainable. I argue that the prevailing culture and experience of schooling contributes to the formation of assumptions, identities, dispositions and orientations to the world characterised by alienation. The Dynamic Paradigm of Learning and Change also contrasts with the assumptions reflected in some educational reform efforts recently promoted at system level in Queensland, Australia. I use the Dynamic Paradigm as the reference point for a formal critique of two influential reform programs, Authentic Pedagogy and the New Basics Project, identifying significant limitations in both the conceptualisation of educational ends and means, and the implementation of these reform agendas. Within the Dynamic Paradigm of Learning and Change, knowledge and learning serve the individual's need for more adaptive or viable functioning in the world. I argue that students' attainment of knowledge of major ways in which others in our culture organise experience (interpret the world) is a legitimate goal of schooling. However, it is more viable to think of the primary function of schooling as providing for the young inspiration, opportunities and support for purposeful doing, and for assisting them in understanding the processes of 'action scheme' change to make such doing more viable. Through the practical-critical components of the inquiry, undertaken in the context of the ferment of pedagogical and curricular discussion and exploration in Queensland between 1999 and 2003, I develop the Key Abilities Model and associated guidelines and resources relating to forms of pedagogy, curriculum organisation and assessment consistent with the Dynamic Paradigm of Learning and Change. I argue the importance of showing teachers why and how their existing visions and conceptions of learning and teaching may be inadequate, and of emphasising teachers' conceptions of learning, knowing, agency and teaching, and their identities, dispositions and orientations to the world, as things that might need to change, in order to realise the intent of educational change focused on transformational student outcomes serving both the individual and collective good. A recommendation is made for implementation and research of a school-based trial of the Key Abilities Model, informed by and reflecting the Dynamic Paradigm of Learning and Change, as an important investment in the development and expression of ‘authentic' human intelligence.

Teacher change in exploring representational approaches to learning science

The researcher worked closely with two biology-trained teachers to plan three teaching sequences in the topics of forces, substances and astronomy that were subsequently taught to Year 7 students. The sequences sought to develop a model of classroom practice that foregrounds students’ negotiation of conceptual representations.

The difficulties encountered by individuals in learning science point to the need for a very strong emphasis of the role of representations in learning. There is a need for learners to use their own representational, cultural and cognitive resources to engage with the subject-specific representational practices of science. Researchers who have undertaken classroom studies whereby students have constructed and used their own representations have pointed to several principles in the planning, execution and assessment of student learning (diSessa, 2004; Greeno & Hall, 1997). A key principle is that teachers need to identify big ideas, key concepts, of the topic at the planning stage in order to guide refinement of representational work. These researchers also point out the need for students to engage with multiple representations in different modes that are both teacher and student generated. A representation can only partially explain a particular phenomenon or process and has both positive and negative attributes to the target that it represents. The issue of the partial nature of representations needs to be a component of classroom practice (Greeno & Hall, 1997) in terms of students critiquing representations for their limitations and affordances and explicitly linking multiple representations to construct a fuller understanding of the phenomenon or process under study. The classroom practice should also provide opportunities for students to manipulate representations as reasoning tools (Cox, 1999) in constructing the scientifically acceptable ideas and communicating them.

Research question: What impact was there on the participating teacher’s practice through the adoption of a representational focus to teaching science?

Data collection included video sequences of classroom practice and student responses, student work, field notes, tape records of meetings and discussions, and student and teacher interviews based in some cases on video stimulated recall. Video analysis software was used to capture the variety of representations used, and sequences of representational negotiation.

The teachers in this study reported substantial shifts in their classroom practices, and in the quality of classroom discussions, arising from adopting a representational focus. The shifts were reported by them as a three-fold challenge. First, there was an epistemological challenge as they came to terms with the culturally produced nature of representations in the topics of force, substance and astronomy and their flexibility and power as tools for analysis and communication, as opposed to their previous assumption that this was given knowledge to be learnt as an end point. The second challenge was pedagogical, in that this approach was acknowledged to place much greater agency in the hands of students, and this brought a need to learn to run longer and more structured discussions around conceptual problems. The third challenge related to content coverage. The teachers sacrificed coverage for the greater depth offered by this approach, and were unanimous in their judgment that this had been a change that had paid dividends in terms of student learning.

State police in a state of change: remaking the entrepreneurial officer

We are currently at a point in time in Australia where questions concerning how to govern police have never been more pressing or more fluid. Systemic corruption has been identified in several states; a range of new accountability mechanisms have been established internal and external to police and in Victoria police corruption has been linked with a violent 'gangland war'. This thesis locates these contemporary developments within a broader analysis of the historical circumstances shaping the changing techniques for governing state police. More specifically, this thesis engages in a detailed comparative study of the changing techniques of governing police in Queensland and Victoria. The theoretical tools to conduct this analysis are drawn from 'governmentality studies'. This refers to a broad grouping of theoretical scholarship concerned with the changing ideas - or 'political rationalities' - on how to govern some thing or some activity, and the underlying reasoning, justifications and ambitions contained within the practical tools or 'techniques' used to govern. Central to the thesis is an argument that a new politics of policing has emerged recently, one that extends the dyad of the old accountability - 'police powers' and 'external accountability' - to a pluralisation of accountability processes and structures. The thesis argues that governmentality studies offer new insights into ways of analysing the techniques for governing state police, increasingly shaped by the managerialisation of governing and embodying efforts to make police innovative, risk-taking problems-solvers. This is what I refer to as an open-ended normative project for re-making the entrepreneurial officer. However, a detailed examination of the development of governmental techniques for 'making up' the entrepreneurial officer indicates that such a governmental project is not implemented unproblematically. Nonetheless, the thesis concludes that the attempts to remake the entrepreneurial officer through the managerialisation of governing presents distinct possibilities for a new 'politics of policing' that fosters deliberative, reflective police practice within a new framework of police accountabilities

Screening and intervention for mental health problems in alcohol and other drug settings: Can training change practitioner behaviour?

Aims: The comorbidity of substance use and mental health problems poses a significant challenge for alcohol and other drug (AOD) treatment services. In many cases, AOD practitioners do not have experience or training in identifying or managing mental health conditions. Methods: This project examined the implementation of screening and intervention practices for mental health disorders among AOD clients. Training and supervision was provided to 20 AOD practitioners across five sites in four agencies with a focus on enhancing skills in detection of, and intervention for, mental health conditions among their clients. A package developed for this purpose, known as PsyCheck, was used. A random file audit was undertaken to examine changes in detection of mental health conditions. Findings: There were significant improvements in detection after training and supervision, with detection rates almost doubling in this time. Conclusions: Training and supervision using the PsyCheck package appears to have the potential to improve mental health detection and intervention in AOD services. This study shows promise for the implementation of mental health intervention in AOD services.

Mind change efficient learning

This paper studies efficient learning with respect to mind changes. Our starting point is the idea that a learner that is efficient with respect to mind changes minimizes mind changes not only globally in the entire learning problem, but also locally in subproblems after receiving some evidence. Formalizing this idea leads to the notion of uniform mind change optimality. We characterize the structure of language classes that can be identified with at most α mind changes by some learner (not necessarily effective): A language class L is identifiable with α mind changes iff the accumulation order of L is at most α. Accumulation order is a classic concept from point-set topology. To aid the construction of learning algorithms, we show that the characteristic property of uniformly mind change optimal learners is that they output conjectures (languages) with maximal accumulation order. We illustrate the theory by describing mind change optimal learners for various problems such as identifying linear subspaces and one-variable patterns.

Sleep in high-functioning children with autism : longitudinal developmental change and associations with behavior problems

Sleep disturbance is common in autism spectrum disorder (ASD), but longitudinal trajectories are poorly defined. This study measured sleep disturbance at baseline and 1 year later examining change over time and associated problem behaviors. Participants were 84 gender-matched children, aged between 7 and 12 years at baseline; 46 children were diagnosed with ASD, and 38 were typically developing (TYP) children. Parent reports on a range of scales were collected. The ASD group had more sleep disturbance than the TYP group. Sleep disturbance decreased over the year in children with ASD, but not in TYP children. Reduced sleep disturbance was associated with improved social ability. Sleep disturbance at baseline predicted later anxiety. Findings indicated different trajectories of sleep disturbance in ASD, and the implications are discussed.

Change and stasis in schoolmusic education in Victoria: the past informing the future

This article reviews the current state of music education in Victoria in terms of both past and present issues. It is argued that many of these issues are the result of change and stasis that have occurred over the past 150 years of school music in Victoria. The principal issues that confront the present generation of music educators and policy makers are the role and place of music in school education and the provision of music teachers for government schools. Both of these issues are discussed in terms of the historical development of music in Victorian schools and it is demonstrated that many of the problems associated with these issues are either cyclical in nature, or have been endemic and simply never adequately addressed. It is suggested that one of the principal challenges to be faced in the government school sector at present is to retain the integrity of music as a discrete subject area in face of the current trend towards a generically-based arts curriculum. There is often a tendency in education to adopt an overly critical and even pessimistic approach to what are perceived as long-standing and seemingly insolvable problems. However, a counter-balancing factor is the rich heritage of Victorian music education which provides the basis for a more optimistic outlook. An important aspect of this heritage is the example of many outstanding music educators in Victoria and elsewhere. It is argued that a knowledge of such past achievements as well as a fuller appreciation of the historical development of music education policies and practices should provide a more informed and rational basis from which to decide the future course of music education in Victoria.

Population based intervention to change back pain beliefs and disability : three part evaluation

Objective To evaluate the effectiveness of a population based, state-wide public health intervention designed to alter beliefs about back pain, influence medical management, and reduce disability and costs of compensation. Design Quasi-experimental, non-randomised, non-equivalent, before and after telephone surveys of the general population and postal surveys of general practitioners with an adjacent state as control group and descriptive analysis of claims database. Setting Two states in Australia Participants 4730 members of general population before and two and two and a half years after campaign started, in a ratio of2:1:1; 2556 general practitioners before and two years after campaign onset. Main outcome measures Back beliefs questionnaire, knowledge and attitude statements about back pain, incidence of workers' financial compensation claims for back problems, rate of days compensated, and medical payments for claims related to back pain and other claims. Results In the intervention state beliefs about back pain became more positive between successive surveys (mean improvement in questionnaire score 1.9 (95% confidence interval 1.3 to 2.5), P<0.001 and 3.2 (2.6 to 3.9), P < 0.001, between baseline and the second and third survey, respectively). Beliefs about back pain also improved among doctors. There was a clear decline in number of claims for back pain, rates of days compensated, and medical payments for claims for back pain over the duration of the campaign. Conclusions A population based strategy of provision of positive messages about back pain improves population and general practitioner beliefs about back pain and seems to influence medical management and reduce disability and workers' compensation costs related to back pain.

Psychometric evaluation of the body change inventory: an assessment instrument for adolescent boys and girls

A new instrument, the Body Change Inventory, was developed to provide an assessment of body change strategies that are used by both adolescent girls and boys. The novel aspect of this instrument is that it evaluates strategies to increase body size and increase muscle size, as well strategies to decrease body size. Independent samples of adolescent girls and boys aged between 11 and 17 years (N=1732) participated in four studies. The revised instrument consisted of three body change scales—Strategies to Decrease Body Size, Strategies to Increase Body Size, and Strategies to Increase Muscle Size. The studies demonstrated content validity, construct validity, internal consistency, and concurrent and discriminant validity for the new scales. The new scales provide a valuable addition in the literature for assessing three global body change strategies among adolescent girls and boys. They are needed in order to examine further the normative development of different kinds of body change strategies and how these may lead to behavioural problems such as disordered eating, exercise dependence, and steroid use.
