The SRI status quo is simply not tenable

The Special Religious Instruction (SRI) debate has been raging in Victoria. Currently, ACCESS Ministries' Christian volunteers deliver 96% of SRI programs in Victoria's government schools. By contrast, "world religions education" replaced Christian religious education in the United Kingdom's government school sector in the mid-1970s.

Religion in Victoria's government schools : a timely debate

While the role of religion in Australian schools has been vigorously debated since the 1870s, it has recently generated considerable controversy, particularly in the State of Victoria. Despite the Victorian Government’s positive record of promoting multifaith engagement, Christian volunteers – provided by ACCESS Ministries - currently teach 96% of students enrolled in Special Religious Instruction (SRI) classes in Victoria’s Government schools.

Backlash as god forced into schools

The Victorian Education Department is forcing public primary schools to run Christian education classes taught by volunteers, angering parents and schools that do not want to host them.

Dietary salt loading impairs arterial vascular reactivity 1-3

BACKGROUND: Studies of sodium have shown improvements in vascular function and blood pressure (BP). The effect of chronic sodium loading from a low-sodium diet to a Western diet on vascular function and BP has been less well studied.

OBJECTIVE: The objective was to examine the effects of dietary salt intake on vascular function and BP.

DESIGN: Thirty-five hypertensive volunteers met the inclusion criteria. After a 2-wk run-in with a low-sodium diet (60 mmol/d), the participants maintained their diets and were randomly assigned to receive sequentially 1 of 3 interventions for 4 wk, with a 2-wk washout between interventions: sodium-free tomato juice (A), tomato juice containing 90 mmol Na (B), and tomato juice containing 140 mmol Na (C). The outcomes were changes in pulse wave velocity (PWV), systolic BP (SBP), and diastolic BP (DBP).

RESULTS: The difference in PWV between interventions B and A was 0.39 m/s (95% CI: 0.18, 0.60 m/s; P = 0.001) and between C and A was 0.35 m/s (95% CI: 0.13, 0.57 m/s; P = 0.01). Differences in SBP and DBP between interventions B and A were 4.4 mm Hg (95% CI: 1.2, 7.8 mm Hg; P = 0.01) and 2.4 mm Hg (95% CI: 0.8, 4.1 mm Hg; P = 0.001), respectively, and between interventions C and A were 5.6 mm Hg (95% CI: 2.7, 8.4 mm Hg; P = 0.01) and 3.3 mm Hg (95% CI: 1.5, 5.0 mm Hg; P = 0.001), respectively. Changes in PWV correlated with changes in SBP (r = 0.52) and DBP (r = 0.58).

CONCLUSIONS: Dietary salt loading produced significant increases in PWV and BP in hypertensive volunteers. Correlations between BP and PWV suggest that salt loading may have a BP-independent effect on vascular wall function. This further supports the importance of dietary sodium restriction in the management of hypertension. This trial was registered with the Australian and New Zealand Clinical Trials Registry as ACTRN12609000161224.

Retroactive interference and mental practice effects on motor performance : a pilot study

This study examined the effect of similar versus dissimilar retroactive interference on the mental practice effects for performing a novel motor skill. Research has shown that mental practice of a motor task can interfere with learning and performance of the task; however, little is known about how different retroactive interference activities affect mental practice effects. 90 volunteers ages 18 to 51 years (M=26.8, SD=9.6) completed a pre-test and post-test of 10 sets of five trials of a throwing task with the non-preferred hand. In the practice phase, participants mentally practiced the throwing task and then mentally practiced a task that was similar, dissimilar, or completed an unrelated reading task. Performance for all groups improved from pre- to post-test; however, there were no differences in increases for the three groups. The findings suggest that mental practice of similar and dissimilar tasks produced no significant interference in performance.

IEF pattern classification-derived criteria for the identification of epoetin-delta in urine

Epoetin-δ (Dynepo™ Shire Pharmaceuticals, Basing stoke, UK) is a synthetic form of erythropoietin (EPO) whose resemblance with endogenous EPO makes it hard to identify using the classical identification criteria. Urine samples collected from six healthy volunteers treated with epoetin-δ injections and from a control population were immuno-purified and analyzed with the usual IEF method. On the basis of the EPO profiles integration, a linear multivariate model was computed for discriminant analysis. For each sample, a pattern classification algorithm returned a bands distribution and intensity score (bands intensity score) saying how representative this sample is of one of the two classes, positive or negative. Effort profiles were also integrated in the model. The method yielded a good sensitivity versus specificity relation and was used to determine the detection window of the molecule following multiple injections. The bands intensity score, which can be generalized to epoetin-α and epoetin-β, is proposed as an alternative criterion and a supplementary evidence for the identification of EPO abuse.

A study of older Australians’ volunteering and quality of life : empirical evidence and policy implications

Older Australians are confronted by dramatic changes in their physical, social, financial, and psychological well-being. There are social costs to these changes related to their productivity and increased costs associated with caring for older Australians. Greater community engagement through voluntary work practice may minimize these costs, as well as positively influence volunteers' subjective quality of life (QOL). This study investigates the motivations for older Australians to engage in formal voluntary work. It seeks to identify whether the motivational factors to volunteer are associated with individuals' subjective QOL. The results indicate a positive relationship between older people's motivations to volunteer and their subjective QOL. This association is strengthened by respondents' community orientation, positive perception of voluntary work, positive personal attitudes toward volunteering, and their self-esteem. The role of policy makers in motivating larger participation by the older groups is discussed.

Gymnasium-based unsupervised exercise maintains benefits in oxygen uptake kinetics obtained following supervised training in type 2 diabetes

Supervised exercise (SE) in patients with type 2 diabetes improves oxygen uptake kinetics at the onset of exercise. Maintenance of these improvements, however, has not been examined when supervision is removed. We explored if potential improvements in oxygen uptake kinetics following a 12-week SE that combined aerobic and resistance training were maintained after a subsequent 12-week unsupervised exercise (UE). The involvement of cardiac output (CO) in these improvements was also tested. Nineteen volunteers with type 2 diabetes were recruited. Oxygen uptake kinetics and CO (inert gas rebreathing) responses to constant-load cycling at 50% ventilatory threshold (V_T), 80% V_T, and mid-point between V_T and peak workload (50% Δ) were examined at baseline (on 2 occasions) and following each 12-week training period. Participants decided to exercise at a local gymnasium during the UE. Thirteen subjects completed all the interventions. The time constant of phase 2 of oxygen uptake was significantly faster (p < 0.05) post-SE and post-UE compared with baseline at 50% V_T (17.3 ± 10.7 s and 17.5 ± 5.9 s vs. 29.9 ± 10.7 s), 80% V_T (18.9 ± 4.7 and 20.9 ± 8.4 vs. 34.3 ± 12.7s), and 50% Δ (20.4 ± 8.2 s and 20.2 ± 6.0 s vs. 27.6 ± 3.7 s). SE also induced faster heart rate kinetics at all 3 intensities and a larger increase in CO at 30 s in relation to 240 s at 80% V_T; and these responses were maintained post-UE. Unsupervised exercise maintained benefits in oxygen uptake kinetics obtained during a supervised exercise in subjects with diabetes, and these benefits were associated with a faster dynamic response of heart rate after training.

The effect of lumbosacral manipulation on corticospinal and spinal reflex excitability on asymptomatic participants

Objective The aim of the study was to examine the effects of a high-velocity, low-amplitude (HVLA) manipulation to the lumbosacral joint on corticospinal excitability, as measured by motor evoked potentials (MEPs) using transcranial magnetic stimulation, and spinal reflex excitability, as measured by the Hoffman reflex (H-reflex).

Methods In a randomized, controlled, crossover design, 14 asymptomatic volunteers (mean age, 23 ± 5.4 years; 10 men; 4 women) were measured for MEPs and H-reflexes immediately before and after a randomly allocated intervention. The interventions consisted of HVLA applied bilaterally to the lumbosacral joint and a control intervention. Participants returned a week later, and the same procedures were performed using the other intervention. Data for H-reflex and MEP amplitudes were normalized to the M-wave maximum amplitude and analyzed using 2-way analysis of variance with repeated measures.

Results A significant interaction of treatment by time was found for MEP (F1,13 = 4.87, P = .04), and post hoc analyses showed that the MEP/M-wave maximum ratio decreased significantly in the HVLA treatment (P = .02; effect size, 0.68). For H-reflex, there was a significant effect of time (F1,13 = 8.186, P = .01) and treatment and time interaction (F1,13 = 9.05, P = .01), with post hoc analyses showing that H-reflexes were significantly reduced after the HVLA manipulation (P = .004; effect size, 0.94). There were no significant changes in MEP latency or silent period duration.

Conclusion An HVLA manipulation applied to the lumbosacral joint produced a significant decrease in corticospinal and spinal reflex excitability, and no significant change occurred after the control intervention. The changes in H-reflexes were larger than those in MEPs, suggesting a greater degree of inhibition at the level of the spinal cord.

Increased plasma peroxides as a marker of oxidative stress in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS)

Background: There is evidence that myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by activation of immune, inflammatory, oxidative and nitrosative stress (IO&NS) pathways. The present study was carried out in order to examine whether ME/CFS is accompanied by increased levels of plasma peroxides and serum oxidized LDL (oxLDL) antibodies, two biomarkers of oxidative stress.

Material/Methods: Blood was collected from 56 patients with ME/CFS and 37 normal volunteers. Severity of ME/CFS was measured using the Fibromyalgia and Chronic Fatigue Syndrome (FF) Rating Scale.

Results: Plasma peroxide concentrations were significantly higher in patients with ME/CFS than in normal controls. There was a trend towards significantly higher serum oxLDL antibodies in ME/CFS than in controls. Both biomarkers contributed significantly in discriminating between patients with ME/CFS and normal controls. Plasma peroxide and serum oxLDL antibody levels were both significantly related to one of the FF symptoms.

Conclusions: The results show that ME/CFS is characterized by increased oxidative stress.

Lower whole blood glutathione peroxidase (GPX) activity in depression, but not in myalgic encephalomyelitis / chronic fatigue syndrome: another pathway that may be associated with coronary artery disease and neuroprogression in depression

BAKGROUND: Major depression and myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) are two disorders accompanied by an upregulation of the inflammatory and oxidative and nitrosative (IO&NS) pathways and a decreased antioxidant status. Moreover, depression is accompanied by disorders in inflammatory and neuroprogressive (IN-PRO) pathways.

METHODS: This study examines whole blood glutathione peroxidase (GPX) in depression and in ME/CFS; GPX is an enzyme that reduces hydroperoxides by oxidizing glutathione and consequently protects the cells from oxidative damage. Blood was sampled in 39 patients with depression, 40 patients with ME/CFS and 24 normal volunteers. Whole blood was analysed for GPX activity using the Ransel assay (Randox). Severity of illness was measured by means of the Hamilton Depression Rating Scale (HDRS) and the Fibromyalgia and Chronic Fatigue Syndrome Rating Scale (FF scale).

RESULTS: We found that whole blood GPX activity was significantly (p=0.001) lower in depressed patients than in normal controls and that there were no significant differences between ME/CFS and controls. In depression and ME/CFS, there were significant and inverse relationships between GPX activity and the FF items, depressed mood and autonomic symptoms. In depression, there were significant and negative correlations between whole blood GPX and the HDRS score and autonomic symptoms.

DISCUSSION: The results show that lowered whole blood GPX activity contributes to the lowered antioxidant status in depression. Since GPX activity is a predictor of neuroprogression and coronary artery disease (CAD), lowered GPX activity in depression contributes to the IN-PRO pathways and the comorbidity between depression and CAD. Our results suggest that patients with depression would benefit from Ebselen or a supplementation with glutathione, N-Acetyl-l-Cysteine and selenium.

Volunteering in a school kitchen garden program : cooking up confidence, capabilities and connections!

This paper reports on the evaluation of a kitchen garden program in primary schools in Victoria, Australia. It focuses on the motivations, impacts, and issues associated with volunteering in the program. The study revealed that volunteers are drawn from a range of sources, including: families of current and former students, former teachers, local residents, clients of aged care and/or disability services, other schools and communities, local universities, community organizations, the community services sector, and the corporate sector. Benefits to volunteers included: opportunities to use time productively, an increased sense of belonging, learning opportunities, and an increased sense of self-worth and enjoyment. For schools, volunteers enhanced engagement between the school and the local community, enabled them to engage more effectively with hard to reach groups, and increased student engagement. In addition, the involvement of volunteers improved the sustainability of the program, improved communication between teachers and families of students from minority ethnic groups, and gave students the chance to relate to new people, to learn from their experience and to have fun in working with the volunteers. Perhaps the most telling benefits to flow both to students and to volunteers were not the “three Rs—reading, w’riting and a’rithmetic” but the three Cs—confidence, capabilities, and connections. However, a clearly identified issue was the importance of matching volunteers’ motivations and needs with the roles they play to sustain current levels of volunteering and, therefore, the program itself.

Crowdsourcing motivations in a not-for-profit GLAM context : the Australian newspapers digitisation program

Crowdsourcing in recent times has become popular among not-for-profits as a means of eliciting members of the public to contribute to activities that would normally have been carried out by staff or by contracting external expertise. The GLAM (galleries, libraries, archives, museums) sector does have a history of involving online volunteers (e.g. reviewing books). Extending that tradition, some GLAM institutions are engaging in crowdsourcing projects to enhance and enrich their collections. But what motivates the public to participate in these crowdsourcing activities? Understanding the unique motivations of participants is needed to establish a motivational framework for GLAM organisations in their not-for-profit context. We present findings from a study of the motivational factors affecting participation in the Australian Newspapers Digitisation Program (ANDP) by the National Library of Australia (NLA). Based on motivational theories and frameworks the study shows that the participants are motivated by a complex framework of personal, collective and external factors. Participants were highly intrinsically motivated, but valued altruistic and community motivations as well. Community and external factors played a vital role in their continued involvement. The paper concludes with a conceptual framework of the motivational factors for crowdsourcing participants in a GLAM context based on the motivational dynamics observed in the ANDP case.

Communities of memory? The Jewish holocaust museum and research centre, Melbourne

The Jewish Holocaust Museum and Research Centre (JHC), Melbourne, opened in 1984. Through the support of large numbers of Jewish people, it has become an impmiant part of their lives as they age, a place of solace and memorialisation. It is a second home for some, providing networking support within and between the different Jewish ethnic communities. This paper will draw on the JHC's ever growing videotestimony collection as well as oral interviews on the roles played by Melbourne survivor volunteers and others in developing the Centre. The survivors have experienced many different aspects of the Holocaust, have come from all over Europe and elsewhere, and 1 are sometimes culturally very different. It will discuss the role played by the various social and cultural communities in creating and responding to the JHC and the success they have had in establishing 'communities of memory' or, alternatively, representing and 1 contextualising the various social and cultural communities.

On memory, affect and atonement : the Long Tan memorial cross(es)

This article analyses the history of the Long Tan Memorial in Vietnam in order to open up a space for engaging with the memorialisation of war as something that can go beyond nationalistic sentimentality and create a space for more complex political and social engagements. In doing so I am concerned with exploring the value of an approach to heritage significance that prioritises relationships between places and peoples rather than authenticity and originality. I explore this question by making use of the fact that the Australian War Memorial has borrowed the original Long Tan Cross now in the custodianship of the Dong Nai Museum for a special exhibition to commemorate the Vietnam War. The Australian Vietnam Volunteers Reconstruction Group, who has official custodianship of the replica cross at the Long Tan Memorial site in Vietnam, has expressed disquiet over the loan. I use the Acting Director’s reply to the AVVRG’s Chairman to open up a discussion about the differences in meanings between these two crosses, what underlies these and how we might theorise them in order to open up an understanding of war heritage that recognises its potentials and its limitations.
