EBSD analysis of a Ti-IF steel subjected to hot torsion in the ferritic region

The effect of grain size on the warm deformation behaviour of a titanium stabilized interstitial free steel was investigated using hot torsion. Tests were performed at temperatures between 765 °C and 850 °C at strain rates between 0.003 s−1 and 1 s−1 for samples with grain sizes of 25 μm, 75 μm and 150 μm. The structures were observed using EBSD analysis and are consistent with those expected for materials dominated by dynamic recovery. Some evidence was found for small amounts of thermally induced migration of pre-existing boundary (bulging) and for the generation of new segments of high angle boundaries by continuous dynamic recrystallization. The early onset of a steady-state flow stress in the finer grained samples is attributed to one or a combination of thermally induced boundary migration and enhanced rates of recovery near subgrain (and grain) boundaries.

Developing a stakeholder analysis to aid bio-based product innovation

Purpose – The results which that study seeks to report are the first part of a larger research programme funded by the New Zealand Foundation for Research, Science & Technology (FRST) aimed at gaining a better understanding of stakeholder perceptions in relation to bio-based products.

Design/methodology/approach – Utilising three chemically modified wood products, data were collected from focus groups and questionnaires and centred primarily on perceptions surrounding the acceptability of building materials that have been bio-modified. Irrespective of the type of chemical modification, family health and durability were the most important factors identified.

Findings – The study finds that product cost rated lower in the 16 factors evaluated, and energy used in production was of little concern. When comparing the three products to one another, two distinct groups with quite differing purchasing philosophies were identified and these perspectives significantly influenced perceptions of product acceptability and willingness to purchase. Utilising a paired comparison technique, an investigation of trade-offs indicated preference for performance over cost and product familiarity. Similarly, low chemical emissions were also preferred over cost considerations. Among the findings, there was scepticism regarding trust in manufacturers to adequately safeguard health and safety and to have a minimum impact on the environment. Low levels of trust were expressed in regard to manufacturers' concern for future generations.

Originality/value – The paper develops an investigative framework which could be applied to the evaluation of products arising from bio-material technology innovation and recommendations for future research directions.

How farmers learn : different approaches to change

This paper presents findings of an Australian study that investigated how farm- management teams go about learning to manage their businesses, including how they learn in order to make strategic and tactical changes. The Australian farming context is one of increasing complexity and risk that demands greater sophistication and professionalism in farm management. Learning is related to increased capacity to manage successful change. Farm-management teams employ four different learning patterns when making changes to their management and marketing practices. Learning patterns are termed local focussed, people focussed, outward looking and extensive networking. These patterns appear to be related to ongoing learning practices of farm-management teams as well as to learning for change. Local focussed management teams learnt for change by accessing only local sources (including government extension services) or a single individual. People focussed farm-management teams preferred to learn for change principally by seeking information and advice on a one-to-one basis from more than one person, most frequently experts, but often other farmers. The remaining farm businesses accessed a variety of sources. The group classed as extensive networkers accessed a large number of varied sources in learning for change. Others who used a less extensive range were termed outward looking.

Interactional infrastructure in rural communities : matching training needs and provision

This paper reports some of the main lessons learnt from a collaborative project titled Generating jobs in regional Tasmania: a social capital approach investigating how two small rural Tasmanian communities could better match local training needs with training provision. The project was conducted within the context of the wider social, economic and demographic changes affecting the two rural communities and their ongoing efforts to manage such change. The paper provides a profile of the two communities with particular attention to their local education, training and employment infrastructure. Three research questions in terms of improving the contributions of leadership, partnerships and social capital are addressed. Development and utilisation of social capital, particularly in the form of interactional infrastructure (defined as opportunities and structures for interaction in a community) that brought together the range of stakeholders, appeared the key to successfully matching needs with provision.

An empirical study on the relationship between intellectual ability and an understanding of the legal process in male remand prisoners

Research conducted in Australia and around the world in the last decade has shown that people with significant intellectual impairments are over-represented in all areas of the criminal justice system. They are particularly over-represented in remand populations appearing before court. Previous research has suggested that as many as one-quarter of offenders facing sentencing in court have difficulty in understanding court procedures and it is suspected that a majority of these individuals suffer a significant intellectual impairment. The purpose of this study was to establish whether remandees with significant intellectual impairments (IQ < 70) have an accurate understanding of the court system. Seventy-four remand prisoners took part in the study. Remandees with an IQ of less than 70 demonstrated a significantly poorer understanding of the court system than those remandees with an IQ of 70 and above. The implications of these results are discussed in relation to the need for law reform and diversionary practices for this population of remandees.

Burnout in physicians : a case for peer-support

Background: It is well documented that doctors experience a high level of stress in their profession, and that this can lead to physical, psychological, and emotional harm, in particular, burnout. Overseas (especially in the UK and USA), research investigating the levels of stress, burnout, and associated psychiatric morbidity in health professionals, across many specialities, has been carried out with a view to prevention of these adverse outcomes.

Aims: To assess the level of burnout in a sample of New Zealand physicians, the associated work and personal characteristics, and the need for development of a support peer supervision or support system.

Methods: Questionnaires that measured a number of work and personal characteristics, including the Maslach Burnout Inventory, the General Health Questionnaire, and additional questions regarding mistakes, and need for support, were sent to 83 physicians in the Waikato and Bay of Plenty areas. Analysis involved descriptive statistics, with t-tests for comparison with other studies, Pearson Product-Moment correlations between variables and analysis of variance where appropriate.

Results: Of the 50 respondents, 28% experienced high levels of two or three aspects of burnout (emotional exhaustion, depersonalization, low personal accomplishment). Emotional exhaustion correlated with a greater need for support. Most respondents favoured a one-to-one support system.

Conclusion: This study highlights the presence of significant workplace difficulties for physicians and the need to develop a preventative support system for the protection of physicians and the patients in their care.

The adverse effect of dummy auction bids on market value

The popularity of an auction as a means of selling residential real estate has increased markedly in recent years. The effectiveness of an auction program is heavily promoted by most real estate agents, claiming it to be the best means of attracting the best price from the highest bidder, It is based on the theory of gathering all buyers together at a publicised time, and then offering the property for sale to the open market.

In theory, the person most willing to buy the property will have the highest bid, supposedly agreeing at market value with the vendor (although above the vendor's reserve I. Unfortunately, the practice of dummy bidding has recently resurfaced and highlights serious flaws in the auction system, with hundreds of residential auctions conducted across Australia every weekend.

Clearly, it is in the vendor's best interests land the auctioneer's best interests, who is paid even more by the vendor if the price is higherl to achieve the highest offer from the last bidder. The tactic of dummy bids is designed to deceive genuine purchasers into a false sense of perception, where there appears to be more competition for the property than there actually exists.

This paper examines the auction process with the emphasis placed on the practice of dummy biding, It considers the broad implications for the definition of market value and also the overall residential market. Useful advice is also included for real estate valuers relying upon auction sale properties in their market analysis. As well as strongly supporting the auction concept, the authors suggest improvements to the overall auction process to ensure relevance to the definition of market value is maintained.

An ABC approach to assessing the risk of violence at triage

There is evidence to suggest that the incidence of violent behaviour in the emergency department by patients toward staff is on the rise. As part of the process of determining urgency, triage nurses must assess the risk of violence at point of entry. The risk of violence, that is, behaviour that either involves a threat of physical or psychological harm to one's self or to others, is considered a critical predictor of urgency in mental health triage. A rapid violence risk assessment strategy will be described which can be utilised in emergency department triage.

What's needed to increase research capacity in rural primary health care

The aim of this study is to identify ways to build research capacity within primary health. A consultation was undertaken in late 2004 using a combination of a one-page survey and a guided meeting format, in a primary health setting in rural NSW. Most (81.3%) of the 134 individuals consulted were part of an Area Health Service, with 12.7% from non-government settings. Most (80.6%) were clinicians, with a third (31.5%) nurses, 8.3% in medicine, and the remainder from a range of allied health professions. Eleven organisations were represented. The main  outcome measures were identification of support needs, processes to enhance research engagement, and barriers and enablers to clinicians’ research  involvement. The results showed that popular delivery modes for research training and support were courses and “one-to- one” advice. Writing topics were generally more popular than others. Common barriers were time and technology issues. A key enabler was a discipline-specific focus. This is one of few rural Australian  consultations on research needs in primary health conducted with a diverse  range of clinicians at the clinician level. It will direct future research capacity  building efforts towards maximising face-to-face discipline specific options and  minimising technology use.

Market fit, market orientation, and business performance : an empirical investigation

This thesis investigated the congruence of an organisation to its intended target markets. It was hypothesised that the internal activities of an organisation are, potentially, structured in response to its market dynamics with the ultimate aim of achieving the organisational objective(s). Market fit has been conceptualised to represent the fit of an organisation to its operating market environment. The information for this study was collected from senior marketing decision makers, using a self-administered questionnaire. The sample comprised 216 companies from a mix of industries and organisational sizes in Australia. There is evidence to suggest that the association of market orientation and business performance is inconsistent under different business operating circumstances, due to the exclusion of the influence of key environmental moderators. The model of market fit attempts to overcome this condition. The results suggest that market fit is associated with measures of business performance, and the levels of association are different from those related to the market orientation measures, reflecting the influence of moderators. The categories of environmental moderators contributing at different levels to the market fit measure include: (1) marketing planning, (2) implementation of marketing decisions, (3) market orientation, (4) market strength, (5) generic strategies, (6) organisational culture, (7) familiarity with the marketing audit, and (8) the external environment. The marketing audit procedure has been recommended as a tool to assist with the establishment and maintenance of market fit. The results of this study indicate that organisational familiarity with, and the conduct of, the marketing audit periodically are low, and that market fit may be a better predictor of business performance, than is market orientation.

Women's cognitive and emotional processing during sexual arousal : the effects of erotic film and absorption

Sexual arousal is a complex and dynamic element of women’s sexuality. Accounts vary, however most multidimensional models highlight the cognitive, affective and physiological components of the female sexual arousal response. While literature examining the peripheral physiological changes that occur during female sexual arousal abounds, there has been a dearth of literature pertaining to the cognitive and affective components. Thus, while many authors have included cognitive and emotions as independent components of the female sexual arousal response, there has been little empirical research to validate this approach. The aim of the current thesis was to examine the cognitive and affective components of female sexual arousal in more depth, investigating the nature of the relationship between these components under various experimental conditions. In order to do so, two integrated studies were conducted, each highlighting the effects of either external or internal variables on women’s subjective sexual arousal, absorption, positive affect and negative affect. Study One was designed to evaluate women’s emotional and cognitive processing of two elements of erotic film – foreplay and erotic context. 60 women were asked to report their subjective sexual arousal, absorption, positive affect and negative affect in response to one of four erotic film excerpts. The erotic excerpts varied in accordance with the degree of foreplay (low vs. high) depicted and the context in which the sexual activities took place (novel vs. habitual context). Women in the study responded more favourably to the high foreplay erotic film excerpt, subsequently reporting higher degrees of subjective sexual arousal, absorption and positive affect. Women also responded favourably to the erotic excerpt filmed in a novel context, reporting greater subjective sexual arousal as a result. The environment in which the sexual encounters were filmed failed to have an effect however, on women’s absorption or their positive or negative affect. The results of Study One suggest that stimulus specific variables, such as the degree of foreplay depicted, have a significant influence on female cognitive and emotional processing of erotic film. The results also suggest that a relationship exists between absorption, subjective sexual arousal and positive affect, albeit a correlational one. Specifically, there was evidence of parallel processing during sexual arousal, as participant reported sexual arousal, absorption and positive affect all increased and decreased in unison. Based on the results it was suggested that future research attempt to experimentally manipulate one of these variables, to examine its direct effect on the remaining variable. Thus, Study Two aimed to examine the effects of absorption on women’s cognitive and emotional processing of erotica. Study Two manipulated absorption at two levels (high vs. low), examining the impact of these states on participants’ subsequent absorption, subjective sexual arousal and positive and negative affect. 62 women were asked to read one of two sets of test session instructions. The first, participant-oriented instruction set, instructed participants to immerse themselves in the erotic film excerpt, as if they were active participants in the sexual exchange. The second, spectator-oriented instruction set, directed participants to observe and evaluate the erotic film. These instructions were designed to elicit high and low degrees of absorption, respectively. The utility of this approach when manipulating female absorption, was demonstrated by self reported ratings of absorption, given at the conclusion of the film presentation. Participants were also asked to report their subjective sexual arousal and positive and negative affect at the conclusion of the erotic film presentation. The findings of this study suggest that the adoption of a participant-oriented (high absorption) perspective elicits more favourable responses from participants than a spectator-oriented (low absorption) perspective, with participants in the former experimental group reporting greater degrees of subjective sexual arousal and positive affect. Negative affect was equivalent across experimental conditions, with the participants reporting that they experienced little to no aversive feelings during either of the experimental conditions. The results suggest that the degree to which a women immerses and absorbs herself in a sexual stimulus has a significant impact in her subsequent cognitive and affective processing of that stimulus. More specifically, it appears that women respond more favourably when they are highly absorbed and immersed in a stimulus, reporting greater subjective sexual arousal and positive affect. Overall, the results of Studies One and Two highlight the dynamic and complex nature of female sexual arousal. It appears that women have definite cognitive and affective responses to sexual stimuli. The magnitude of these responses may be mediated by a number of factors however, including the intrinsic qualities of the stimulus and the degree to which the woman attends to the stimulus. Both these variables act to either enhance or inhibit the sexual arousal response. There results have important implications for current sexuality literature. While women’s cognitions and emotions in response to erotic film were generally highly correlated, in some instances they differed, warranting their inclusion as separate elements in models of female sexual arousal. Furthermore, it might be suggested that the inclusion of an additional variable – absorption – into current models of female sexual arousal would prove beneficial, aiding researchers to better understand and predict the arousal process. As such, recommendations are made for a revised model of female sexual arousal. In terms of future directions, the results of the present thesis have implications for the treatment of sexual dysfunctions, suggesting that clinicians need to understand the internal and external variables that might contribute to the aetiology and maintenance of their presenting problems.

Funding special education provision by means of discriminant function analysis

This thesis is concerned with the development of a funding mechanism, the Student Resource Index, which has been designed to resolve a number of difficulties which emerged following the introduction of integration or inclusion as an alternative means of providing educational support to students with disabilities in the Australian State of Victoria. Prior to 1984, the year in which the major integration or inclusion initiatives were introduced, the great majority of students with disabilities were educated in segregated special schools, however, by 1992 the integration initiatives had been successful in including within regular classes approximately half of the students in receipt of additional educational assistance on the basis of disability. The success of the integration program brought with it a number of administrative and financial problems which were the subject of three government enquiries. Central to these difficulties was the development of a dual system of special education provision. On one hand, additional resources were provided for the students attending segregated special schools by means of weighted student ratios, with one teacher being provided for each six students attending a special school. On the other hand, the requirements of individual students integrated into regular schools were assessed by school-based committees on the basis of their perceived extra educational needs. The major criticism of this dual system of special education funding was that it created inequities in the distribution of resources both between the systems and also within the systems. For example, three students with equivalent needs, one of whom attended a special school and two of whom attended different regular schools could each be funded at substantially differing levels. The solution to these inequities of funding was seen to be in the development of a needs based funding device which encompassed all students in receipt of additional disability related educational support. The Student Resource Index developed in this thesis is a set of behavioural descriptors designed to assess degree of additional educational need across a number of disability domains. These domains include hearing, vision, communication, health, co-ordination (manual and mobility), intellectual capacity and behaviour. The completed Student Resource Index provides a profile of the students’ needs across all of these domains and as such addresses the multiple nature of many disabling conditions. The Student Resource Index was validated in terms of its capacity to predict the ‘known’ membership or the type of special school which some 1200 students in the sample currently attended. The decision to use the existing special school populations as the criterion against which the Student Resource Index was validated was based on the premise that the differing resource levels of these schools had been historically determined by expert opinion, industrial negotiation and reference to other special education systems as the most reliable estimate of the enrolled students’ needs. When discriminant function analysis was applied to some 178 students attending one school for students with mild intellectual disability and one facility for students with moderate to severe intellectual disability the Student Resource Index was successful in predicting the student's known school in 92 percent of cases. An analysis of those students (8 percent) which the Student Resource Index had failed to predict their known school enrolment revealed that 13 students had, for a variety of reasons, been inappropriately placed in these settings. When these students were removed from the sample the predictive accuracy of the Student Resource Index was raised to 96 percent of the sample. By comparison the domains of the Vineland Adaptive Behaviour Scale accurately predicted known enrolments of 76 percent of the sample. By way of replication discriminant function analysis was then applied to the Student Resource Index profiles of 518 students attending Day Special Schools (Mild Intellectual Disability) and 287 students attending Special Developmental Schools (Moderate to Severe Intellectual Disability). In this case, the Student Resource Index profiles were successful in predicting the known enrolments of 85 percent of students. When a third group was added, 147 students attending Day Special Schools for students with physical disabilities, the Student Resource Index predicted known enrolments in 80 percent of cases. The addition of a fourth group of 116 students attending Day Special Schools (Hearing Impaired) to the discriminant analysis led to a small reduction in predictive accuracy from 80 percent to 78 percent of the sample. A final analysis which included students attending a School for the Deaf-Blind, a Hospital School and a Social and Behavioural Unit was successful in predicting known enrolments in 71 percent of the 1114 students in the sample. For reasons which are expanded upon within the thesis it was concluded that the Student Resource Index when used in conjunction with discriminant function analysis was capable of isolating four distinct groups on the basis of their additional educational needs. If the historically determined and varied funding levels provided to these groups, inherent in the cash equivalent of the staffing ratios of Day Special Schools (Mild Intellectual Disability), Special Development Schools (Moderate to Severe Intellectual Disability), Day Special Schools (Physical Disability) and Day Special Schools (Hearing Impairment) are accepted as reasonable reflections of these students’ needs these funding levels can be translated into funding bands. These funding bands can then be applied to students in segregated or inclusive placements. The thesis demonstrates that a new applicant for funding can be introduced into the existing data base and by the use of discriminant function analysis be allocated to one of the four groups. The analysis is in effect saying that this new student’s profile of educational needs has more in common with Group A than with the members of Groups B, C, or D. The student would then be funded at Group A level. It is immaterial from a funding point of view whether the student decides to attend a segregated or inclusive setting. The thesis then examines the impact of the introduction of Student Resource Index based funding upon the current funding of the special schools in one of the major metropolitan regions. Overall, such an initiative would lead to a reduction of 1.54 percent of the total funding accruing to the region’s special schools.

Effectiveness of recording in primary science : a study of the ability of junior primary school pupils to use drawing as an effective method of communication in science lessons

Drawing as a means of recording is a very common practice in junior primary science lessons. This is largely due to the availability of necessary materials. Also, most youg children have some degree of drawing skill and enjoy drawing activities. Since 1956 the science curriculum to be implemented in primary classrooms in Victoria has changed from one that was based largely on nature study (biological) to one that includes physical and technological aspects. Further, there have been changes in the teaching methodologies advocated for use in science lessons. A modified Interactive Teaching Approach was used for the studies. Drawing was the main means by which the children recorded information. The topic of 'shells' was used to enable collection of data about the children's enjoyment of the activity and satisfaction with their achievement. This study was replicated using the topic 'rocks'; again data were collected concerning satisfaction and enjoyment. During a series of lessons on 'snails' data were collected concerning the achievement of 'process' and 'objective' purposes that teachers might have in mind when setting a drawing activity. In addition to providing data about purposes the study stimulated some questions regarding the techniques the children had used in their drawings. Accordingly, data concerning the use of graphic techniques by the children were collected during a series of lessons on 'oils'. The data collected and analysed in the various studies highlighted the value of drawing in junior primary school science lessons. It also validated strategies developed by the author and designed to help teachers and children use drawing effectively in science activities.

Cross-cultural adaptation of a tobacco questionnaire for Punjabi, Cantonese, Urdu and Sylheti speakers: qualitative research for better clinical practice, cessation services and research.Â

Objective : To develop cross‐culturally valid and comparable questionnaires for use in clinical practice, tobacco cessation services and multiethnic surveys on tobacco use.
Methods : Key questions in Urdu, Cantonese, Punjabi and Sylheti on tobacco use were compiled from the best existing surveys. Additional items were translated by bilingual coworkers. In one‐to‐one and group consultations, lay members of the Pakistani, Chinese, Indian Sikh and Bangladeshi communities assessed the appropriateness of questions. Questionnaires were developed and field tested. Cross‐cultural comparability was judged in a discussion between the researchers and coworkers, and questionnaires were finalised. Questionnaires in Cantonese (written and verbal forms differ) and Sylheti (no script in contemporary use) were written as spoken to avoid spot translations by interviewers.
Results : The Chinese did not use bidis, hookahs or smokeless tobacco, so these topics were excluded for them. It was unacceptable for Punjabi Sikhs to use tobacco. For the Urdu speakers and Sylheti speakers there was no outright taboo, particularly for men, but it was not encouraged. Use of paan was common among women and men. Many changes to existing questions were necessary to enhance cultural and linguistic appropriateness—for example, using less formal language, or rephrasing to clarify meaning. Questions were modified to ensure comparability across languages, including English.
Conclusion : Using theoretically recommended approaches, a tobacco‐related questionnaire with face and content validity was constructed for Urdu, Punjabi, Cantonese and Sylheti speakers, paving the way for practitioners to collect more valid data to underpin services, for sounder research and ultimately better tobacco control. The methods and lessons are applicable internationally.

Understanding property cycles in a residential market

Purpose – This paper aims to review property cycle theory and the relevance of the larger body of knowledge about cycles with reference to the housing market. It also aims to highlight the lack of research into property cycles in the residential sector on a suburb or smaller region basis, as well as the potential for increased knowledge about cycles to assist to avoid housing stress.

Design/methodology/approach – The paper conducts a literature review of previous cycle research and encourages the use of cycle theory. It discusses the established body of knowledge about business cycles and the office market sector, as well as investigating levels of housing affordability and how detailed knowledge about property cycles can assist to decrease housing affordability in residential areas, which will eventually experience a downturn.

Findings – It is argued that an increased level of certainty about cycle behaviour in particular suburbs will give households a higher level of confidence when considering whether and when to enter the market. Property cycle research has the potential to assist low-income homeowners to better understand the characteristics of cycles and associated risks in each residential.

Research limitations/implications – This is a conceptual paper and has conducted a review of cycle research and housing affordability in certain countries. Some areas or countries may be affected to varying degrees by property cycles and levels of housing affordability.

Practical implications – In extended periods of high volatility it is argued that a better understanding of housing cycles will allow more homeowners to avoid negative equity and the stress associated with repossessions. Property cycles are unavoidable although there is typically relatively little information available in the open market about the timing and amplitude of cycles in individual areas.

Originality/value – This paper is unique as it highlights the potential for property cycles to be used to avoid housing stress in the residential market. Traditionally cycle research is used to increase returns and avoid downturns in the office and/or business sectors.
