An analysis of microband orientation in hot deformed aluminium alloy AA5052 using forward and reverse torsion

The effects of strain path reversal on the macroscopic orientation of microbands in AA5052 have been studied using high resolution electron backscatter diffraction. Deformation was carried using two equal steps of forward/forward or forward/reverse torsion at a temperature of 300°C and strain rate of 1s-1 to a total equivalent tensile strain of 0.5. In both cases microbands were found in the majority of grains examined with many having more than one set. The microbands appear to cluster at specific angles to the macroscopic deformation. For the forward/forward condition microbands clustered around -20° and +45° to the maximum principle stress direction and at ± 30-35° to the principal strain direction. For the forward/reverse condition significantly more spread in microband angle was observed though peaks were visible at ±35° with respect to principal stress direction and at -40° and +30° with respect to the principal strain direction of the reverse torsion. This suggests the microbands formed in the forward deformation have or are dissolving and any new microbands formed are related to the deformation conditions of the final strain path.

Quality in disability service - whose indicators?

The study identified indicators of disability service quality used by three stakeholder groups (service users, providers and managers) in order to develop an explanatory schema regarding stakeholders' perceptions of quality and its indicators. The different perspectives were identified and the emerging quality indicator framework had a complex socio-ecological basis.

Use of poverty indicators and the poverty pyramid for agricultural and rural development in the smallholder sector in Sri Lanka

Based on official micro-level poverty studies for agricultural and rural development in the smallholder sector of Sri Lanka. The Poverty Pyramid was found to be a powerful tool for poverty analysis and the design of poverty alleviation strategies that are targeted at sustained poverty alleviation. Identification of the correct target groups by factors that prevent them from being more productive in their income generation activities is crucial to the formulation of rural development programs that benefit poor people first and most.

Students' perceptions of the value of the elements of an online learning environment : looking back in moving forward

In 2003, Deakin University implemented a centralised learning management system (LMS) under the banner of Deakin Studies Online (DSO), as well as implementing policies requiring all its units of study to have at least a basic online presence from 2004. Given the scope of the university's commitment to online education, it was considered essential to evaluate the effectiveness of this investment. Based on more than 5400 responses obtained from students in 2004 and 2005 as part of the DSO evaluation survey, the analysis presented here identifies those elements of the online learning environment (OLE) that are most used and valued by students, those elements of the OLE that students most want to see improved, and, those factors that most contribute to students' perceptions that use of the OLE enhanced their learning experience. The most used and valued elements were core LMS functions, including accessing unit information, accessing lecture/tute/lab notes, interacting with unit learning resources, reading online discussions, contacting lecturers/tutors and submitting assignments online. The OLE elements identified as most needing attention were receiving feedback on assignments; viewing my marks; and reviewing unit progress. Students felt that using DSO enhanced their learning experience when they were adequately supported by unit teachers and technical support services; when they were able to find and use unit information; and when they were able to read the online contributions of other unit members. The retrospective analysis of data collected in the period 2004-2005 has been shaped by a forward-looking agenda. The array of elements available within, and in association with, traditional LMSs which has emerged since that time raises the future challenge of how to maximise and evidence educational value through the optimal combination of elements from the portfolio of e-learning technologies increasingly available to educators.

The resident assessment instrument-minimum data set 2.0 quality indicators : a systematic review

Background
The Resident Assessment Instrument-Minimum Data Set (RAI-MDS) 2.0 is designed to collect the minimum amount of data to guide care planning and monitoring for residents in long-term care settings. These data have been used to compute indicators of care quality. Use of the quality indicators to inform quality improvement initiatives is contingent upon the validity and reliability of the indicators. The purpose of this review was to systematically examine published and grey research reports in order to assess the state of the science regarding the validity and reliability of the RAI-MDS 2.0 Quality Indicators (QIs).

Methods
We systematically reviewed the evidence for the validity and reliability of the RAI-MDS 2.0 QIs. A comprehensive literature search identified relevant original research published, in English, prior to December 2008. Fourteen articles and one report examining the validity and/or reliability of the RAI-MDS 2.0 QIs were included.

Results
The studies fell into two broad categories, those that examined individual quality indicators and those that examined multiple indicators. All studies were conducted in the United States and included from one to a total of 209 facilities. The number of residents included in the studies ranged from 109 to 5758. One study conducted under research conditions examined 38 chronic care QIs, of which strong evidence for the validity of 12 of the QIs was found. In response to these findings, the 12 QIs were recommended for public reporting purposes. However, a number of observational studies (n=13), conducted in "real world" conditions, have tested the validity and/or reliability of individual QIs, with mixed results. Ten QIs have been studied in this manner, including falls, depression, depression without treatment, urinary incontinence, urinary tract infections, weight loss, bedfast, restraint, pressure ulcer, and pain. These studies have revealed the potential for systematic bias in reporting, with under-reporting of some indicators and over-reporting of others.

Conclusion
Evidence for the reliability and validity of the RAI-MDS QIs remains inconclusive. The QIs provide a useful tool for quality monitoring and to inform quality improvement programs and initiatives. However, caution should be exercised when interpreting the QI results and other sources of evidence of the quality of care processes should be considered in conjunction with QI results.

Exploring the Australian Science Curriculum : A way forward?

There is considerable international concern about science education based on the number of students engaged with science and mathematics, and research showing student disenchantment with school science curricula. ln this presentation I will trace through a history of concerns with school science, and describe the recommendations and curriculum responses to these concerns internationally and particularly in Australia. The new Australian Science Curriculum is based around ideas related to scientific literacy and inquiry curriculum, and includes science inquiry skills and science as a human endeavour' as major strands. I will describe the features of the course and raise the question - does it represent a productive way forward? The various aspects of the course are related to current directions in science education research, and examples will be given of my own involvement in national curriculum initiatives, into school-community links, and Deakin research into a pedagogy that focuses on student generation of representations, as examples of ways forward for improving student engagement with learning science.

HRM research in China : looking back and looking forward

Purpose – The purpose of this paper is to provide an overview of the field of human resource management (HRM) in China, with insights drawn from recent times to several millennia earlier, with a view to informing the further work that needs to be done to better understand managing people in China.
Design/methodology/approach – The authors examined Chinese ancient texts related to people management and drew on reviews of HRM research in China since the establishment of the People’s Republic of China in 1949 till current times, to draw lessons for HRM in China today and for the future.
Findings – The 2,500 year gap that separates the literatures studied as part of this review cannot hide the striking similarities between the conceptual views about the importance of people and their management in the two periods. Yet, there remains a lack of empirical studies of the Chinese style of HRM practices. The majority of recent research in the field of HRM in China is focussed on comparison between HRM practices in various types of enterprises operating in China and those in the west, with the apparent aim of better understanding the latter rather than the former.
Originality/value – As China is rapidly becoming a key global player, and its enterprises represent an increasing share of the global market, it is crucial to understand how Chinese firms have managed their people at home and globally to achieve performance outcomes. Are there lessons other firms, especially those in emerging markets could learn? What are the implications for building global
management and organisational knowledge? This paper provides some directions for future research about HRM in China, which may help gain a better understanding of the Chinese style of management and further develop management and organisation theories in the China context.

Flexible multibody approach in forward dynamic simulation of locomotive strains in human skeleton with flexible lower body bones

A method for bone strain estimation is examined in this article. The flexibility of a single bone in an otherwise rigid human skeleton model has been studied previously by various authors. However, in the previous studies, the effect of the flexibility of multiple bones on the musculoskeletal model behavior was ignored. This study describes a simulation method that can be used to estimate the bone strains at both tibias and femurs of a 65-year old Caucasian male subject. The verification of the method is performed by the comparison of the results with other studies available in literature. The results of the study show good correlation with the results of previous empirical studies. A damping effect of the flexible bones on the model is also studied in this paper.

Mental health, criminal justice and culture : some ways forward?

Objective: This paper aims to offer an overview of the mental health needs of Indigenous men and women in the criminal justice system and how Indigenous cultural perspectives on mental health might infl uence forensic mental health service provision.
Conclusion: There is a need for both mental health and criminal justice agencies to collaborate more closely in developing new models of service provision that incorporate Indigenous perspectives on social and emotional wellbeing, recognize culturally specifi c mental health risk and protective factors in relation to prevention, early intervention and treatment, and take advantage of the opportunities for treatment that arise in the context of criminal justice system intervention.
