Teacher education to meet the challenges of child sexual abuse

The phenomenon of child sexual abuse has significant implications for teachers’ pre-service training and professional development. Teachers have a pedagogical role in dealing with abused children, and a legal and professional duty to report suspected child sexual abuse. Teachers require support and training to develop the specialised knowledge and confidence needed to deal with this complex context. This article explains the social context of child sexual abuse, its health and educational consequences, and the legal context, showing why teachers require this specialised training. It then reports on findings from an Australian study into the amount of training received by teachers about child sexual abuse, and teachers’ satisfaction with that training. Results have implications for teacher training strategies in pre-service and in-service settings.

Computational approaches to the visual validation of 3D virtual environments

Virtual environments can provide, through digital games and online social interfaces, extremely exciting forms of interactive entertainment. Because of their capability in displaying and manipulating information in natural and intuitive ways, such environments have found extensive applications in decision support, education and training in the health and science domains amongst others. Currently, the burden of validating both the interactive functionality and visual consistency of a virtual environment content is entirely carried out by developers and play-testers. While considerable research has been conducted in assisting the design of virtual world content and mechanics, to date, only limited contributions have been made regarding the automatic testing of the underpinning graphics software and hardware. The aim of this thesis is to determine whether the correctness of the images generated by a virtual environment can be quantitatively defined, and automatically measured, in order to facilitate the validation of the content. In an attempt to provide an environment-independent definition of visual consistency, a number of classification approaches were developed. First, a novel model-based object description was proposed in order to enable reasoning about the color and geometry change of virtual entities during a play-session. From such an analysis, two view-based connectionist approaches were developed to map from geometry and color spaces to a single, environment-independent, geometric transformation space; we used such a mapping to predict the correct visualization of the scene. Finally, an appearance-based aliasing detector was developed to show how incorrectness too, can be quantified for debugging purposes. Since computer games heavily rely on the use of highly complex and interactive virtual worlds, they provide an excellent test bed against which to develop, calibrate and validate our techniques. Experiments were conducted on a game engine and other virtual worlds prototypes to determine the applicability and effectiveness of our algorithms. The results show that quantifying visual correctness in virtual scenes is a feasible enterprise, and that effective automatic bug detection can be performed through the techniques we have developed. We expect these techniques to find application in large 3D games and virtual world studios that require a scalable solution to testing their virtual world software and digital content.

Economic growth and suicide rate changes : a case in China from 1982 to 2005

It is to estimate the trend of suicide rate changes during the past three decades in China and try to identify its social and economic correlates. Official data of suicide rates and economic indexes during 1982–2005 from Shandong Province of China were analyzed. The suicide data were categorized for the rural / urban location and gender, and the economic indexes include GDP, GDP per capita, rural income, and urban income, all adjusted for inflation. We found a significant increase of economic development and decrease of suicide rates over the past decades under study. The suicide rate decrease is correlated with the tremendous growth of economy. The unusual decrease of Chinese suicide rates in the past decades is accounted for within the Chinese cultural contexts and maybe by the Strain Theory of Suicide.

A fragment of the LG3 peptide of endorepellin is present in the urine of physically active mining workers : a potential marker of physical activity

Biomarker analysis has been implemented in sports research in an attempt to monitor the effects of exertion and fatigue in athletes. This study proposed that while such biomarkers may be useful for monitoring injury risk in workers, proteomic approaches might also be utilised to identify novel exertion or injury markers. We found that urinary urea and cortisol levels were significantly elevated in mining workers following a 12 hour overnight shift. These levels failed to return to baseline over 24h in the more active maintenance crew compared to truck drivers (operators) suggesting a lack of recovery between shifts. Use of a SELDI-TOF MS approach to detect novel exertion or injury markers revealed a spectral feature which was associated with workers in both work categories who were engaged in higher levels of physical activity. This feature was identified as the LG3 peptide, a C-terminal fragment of the anti-angiogenic / anti-tumourigenic protein endorepellin. This finding suggests that urinary LG3 peptide may be a biomarker of physical activity. It is also possible that the activity mediated release of LG3 / endorepellin into the circulation may represent a biological mechanism for the known inverse association between physical activity and cancer risk / survival.

A radiological method to determine the accuracy of motion capture marker placement on palpable anatomical landmarks through a shoe

The accuracy of marker placement on palpable surface anatomical landmarks is an important consideration in biomechanics. Although marker placement reliability has been studied in some depth, it remains unclear whether or not the markers are accurately positioned over the intended landmark in order to define the static position and orientation of the segment. A novel method using commonly available X-ray imaging was developed to identify the accuracy of markers placed on the shoe surface by palpating landmarks through the shoe. An anterior–posterior and lateral–medial X-ray was taken on 24 participants with a newly developed marker set applied to both the skin and shoe. The vector magnitude of both skin- and shoe-mounted markers from the anatomical landmark was calculated, as well as the mean marker offset between skin- and shoe-mounted markers. The accuracy of placing markers on the shoe relative to the skin-mounted markers, accounting for shoe thickness, was less than 5mm for all markers studied. Further, when using the developed guidelines provided in this study, the method was deemed reliable (Intra-rater ICCs¼0.50–0.92). In conclusion, the method proposed here can reliably assess marker placement accuracy on the shoe surface relative to chosen anatomical landmarks beneath the skin.

The development of a multi-segment kinematic model of footwear

In gait analysis, both shoe mounted and skin mounted markers have been used to quantify the movement of the foot inside the shoe. However, these models have not been demonstrated as reliable or accurate in shod conditions. The purpose of this study was to develop an accurate and reliable marker set to describe foot-shoe complex kinematics during stance phase.

Footwear modifies coronal plane forefoot and sagittal plane hallux kinematics during stance phase of walking gait

Footwear is designed to reduce injury, and enhance performance. However, the effect footwear has on foot and ankle kinematics currently remains unknown. Acknowledging the need for improved understanding, multi-segment models of the foot-shoe complex need to be established to both describe and quantify the effect footwear has on the foot and ankle during stance phase of gait. The purpose of this study was to quantify how footwear alters the kinematics of the foot inside the shoe during stance phase of walking gait.

‘Show Me Your Wiki and I’ll Show you Mine’: Using Online Interactive Media to Improve Academic Writing and Research in a Public Health Under-Graduate Cohort

The number of Internet users in Australia has been steadily increasing, with over 10.9 million people currently subscribed to an internet provider (ABS, 2011). Over the past year, the most avid users of the Internet were 15 – 24 year olds, with approximately 95% accessing the internet on a regular basis (ABS, Social Trends, 2011). While the internet has been described as fundamental to higher education students, social and leisure internet tools are also increasingly being used by these students to generate and maintain their social and professional networks and interactions (Duffy & Bruns 2006). Rapid technological advancements have enabled greater and faster access to information for learning and education (Hemmi et al, 2009; Glassman and Kang, 2011). As such, we sought to integrate interactive, online social media into the assessment profile of a Public Health undergraduate cohort at the Queensland University of Technology (QUT). The aim of this exercise was to engage students to both develop and showcase their research on a range of complex, contemporary health issues within the online forum of Wikispaces (http://www.wikispaces.com/) for review and critique by their peers. We applied Bandura’s Social Learning Theory (SLT) to analyse the interactive processes from which students developed deeper and more sustained learning, and via which their overall academic writing standards were raised. This paper outlines the assessment task, and the students’ feedback on their learning outcomes in relation to the Attentional, Retentional, Motor Reproduction, and Motivational Processes outlined by Bandura in SLT. We conceptualise the findings in a theoretical model, and discuss the implications for this approach within the broader tertiary environment.

Dose response relationships between physical activity, walking and health-related quality of life in mid-age and older women

Background Although physical activity is associated with health-related quality of life (HRQL), the nature of the dose-response relationship remains unclear. This study examined the concurrent and prospective dose-response relationships between total physical activity (TPA) and (only) walking with HRQL in two age cohorts of women. Methods Participants were 10,698 women born in 1946-1951 and 7,646 born in 1921-1926, who completed three mailed surveys for the Australian Longitudinal Study on Women's Health. They reported weekly TPA minutes (sum of walking, moderate, and vigorous minutes). HRQL was measured with the Medical Outcomes Study Short-Form 36 Health Status Survey (SF-36). Linear mixed models, adjusted for socio-demographic and health-related variables, were used to examine associations between TPA level (none, very low, low, intermediate, sufficient, high, and very high) and SF-36 scores. For women who reported walking as their only physical activity, associations between walking and SF-36 scores were also examined. Results Curvilinear trends were observed between TPA and walking with SF-36 scores. Concurrently, HRQL scores increased significantly with increasing TPA and walking, in both cohorts, with increases less marked above sufficient activity levels. Prospectively, associations were attenuated although significant and meaningful improvements in physical functioning and vitality were observed across most TPA and walking categories above the low category. Conclusion For women in their 50s-80s without clinical depression, greater amounts of TPA are associated with better current and future HRQL, particularly physical functioning and vitality. Even if walking is their only activity, women, particularly those in their 70s-80s, have better health-related quality of life.

Occupational therapy students’ contribution to occasions of service during practice placements in health settings

Currently in the Australian higher education sector, the productivity benefits of occupational therapy clinical education placements are a contested issue. This article will report results of a study that developed a methodology for documenting time use during placements and investigated the productivity changes associated with occupational therapy clinical education placements in Queensland, Australia. Supervisors’ and students’ time use during placements and how this changed for supervisors compared to pre- and post-placement is also presented. Methods: Using a cohort survey design, participants were students from two Queensland universities, and their supervisors employed by Queensland Health. Time use was recorded in 30 minute blocks according to particular categories. Results: There was a significant increase in supervisors’ time spent in patient care activities (F = 94.0112,12.37 df, P < 0.001) between pre- and during placement (P < 0.001) and decrease between during and post-placement (P < 0.001). Supervisors’ time spent in all non-patient care activities was also significant (F = 4.5802,16 df, P = 0.027) increasing between pre- and during placement (P = 0.028). There was a significant decrease in supervisors’ time spent in placement activities (F = 5.1332,19.18 df, P = 0.016) from during to post-placement. Students spent more time than supervisors in patient care activities while on placement. Discussion: A novel method for reporting productivity and time-use changes during clinical education programs for occupational therapy has been applied. Supervisors spent considerable time in assessing and managing students and their clinical education role should be seen as core business in standard occupational therapy practice. This paper will contribute to future assessments of the economic.

Learning to lead : a social justice perspective on understanding elementary teacher leadership in Papua New Guinea

Leadership in elementary education is currently recognized as a political imperative in Papua New Guinea (PNG), as the nation develops strategies towards equitable access to schooling. One recent initiative aimed at building educational leadership was an intensive Australian Leadership Award Fellowship (ALAF) program funded by AusAID, involving a group of 10 teacher trainers from PNG. As part their involvement participants completed self-authored journal entries at the beginning and end of the leadership program. Participants were also involved in focus groups after completion of the initiative. Referring to the experiences of these teacher trainers, this paper draws on Nancy Fraser’s (2005, 2008) social justice framework to examine participants’ views of what constituted effective leadership in elementary education in PNG and how these views may have changed throughout the ALAF program. Key findings of this study included participants’ emphasis on relationships and valuing people in elementary education leadership contexts, participants’ concern about economic/financial barriers to effective leadership in the PNG context and participants’ perception of research as a way to support leadership roles.

Post-graduate health promotion students assess their information literacy

Purpose - The purpose of this paper is to examine post-graduate health promotion students’ self-perceptions of information literacy skills prior to, and after completing PILOT, an online information literacy tutorial. Design/methodology/approach – Post graduate students at Queensland University of Technology enrolled in PUP038 New Developments in Health Promotion completed a pre- and post- self-assessment questionnaire. From 2008-2011 students were required to rate their academic writing and research skills before and after completing the PILOT online information literacy tutorial. Quantitative trends and qualitative themes were analysed to establish students’ self-assessment and the effectiveness of the PILOT tutorial. Findings – The results from four years of post-graduate students’ self-assessment questionnaires provide evidence of perceived improvements in information literacy skills after completing PILOT. Some students continued to have trouble with locating quality information and analysis as well as issues surrounding referencing and plagiarism. Feedback was generally positive and students’ responses indicated they found the tutorial highly beneficial in improving their research skills. Originality/value - This paper is original because it describes post-graduate health promotion students’ self-assessment of information literacy skills over a period of four years. The literature is limited in the health promotion domain and self-assessment of post-graduate students’ information literacy skills. Keywords – Self-assessment, Post-graduate, Information literacy, Library instruction, Higher education, Health promotion, Evidence-based practice Paper Type - Research paper

Journalling and public health education : thinking about reflecting

Purpose: The purpose of this research is to understand reflective journalling in a first year Public Health practice unit. Design/methodology/approach: This research uses pure phenomenography to interpret students descriptions of reflective journalling. Data was collected from thirty-two students enrolled in PUB215 Public Health Practice in the School of Public Health, Queensland University of Technology. Participants completed a brief open-ended questionnaire to evaluate the first assessment item in this unit, a Reflective Journal. Questionnaire responses were analysed through Dahlgren and Fallsberg’s (1991) seven phases of data analysis. Findings: The Reflective Journal required students to reflect on lecture content from five of seven guest speakers. Participants responses were categorised into four conceptions - 1) engagement in learning, 2) depth of knowledge, 3) understanding the process and 4) doing the task. Participants describe reflective journalling as a conduit to think critically about the content of the guest speakers presentations. Other participants think journalling is a vehicle to think deeply about their potential career pathways. Some define journalling as a pragmatic operation where practical issues are difficult to navigate. The Reflective Journal successfully a) engaged students learning, b) increased students depth of knowledge and c) deepened students understanding of the journalling process. Originality/value: This research gives an insight into how first year public health students understand reflective journalling, supports educators in reflective journalling assessments and confirms a Reflective Journal assessment can move student reflection towards higher order thinking about practice.

Nurses and teachers : partnerships for green health promotion

Background: The term ‘green health promotion’ is given to health promotion underpinned by the principles of ecological health and sustainability. Green health promotion is supported philosophically by global health promotion documents such as the Ottawa Charter for Health Promotion (1986) and the ecological public health movement. Green health promotion in schools aims to practice the principles of ecological health and sustainability. Methods: An extended literature review revealed a paucity of literature about green health promotion in schools across disciplines. Literature about nurses and health promotion in schools is generally found in nursing publications. Literature about ecological sustainability in schools is mostly found in teaching publications. Results: This paper explores the nexus between nursing and health promotion, and teachers and ecological sustainability. Collaborative partnerships between health and education do not capitalise on programs such as Health Promoting Schools and the School Based Youth Health Nurse Program in Queensland, Australia. The authors consider how collaborative partnerships between health and education in schools can work towards green health promotion. Conclusion: Nursing’s approach to health promotion and education’s approach to ecological sustainability need to be aligned to enhance green health promotion in schools and promote a new generation of ‘tree huggers and hippies’.
