Doing justice' : stories of everyday life in disadvantaged schools and neighbourhoods

I worked as a school administrator in 'disadvantaged schools' for many years. In this study I asked colleagues from sixteen schools in the northern and western suburbs of Adelaide to co - theorise about changes in their neighbourhood, school populations and programs, now that their schools are no longer recognised by policy as 'disadvantaged1. I explore the use of narrative method and arts based approaches by constructing a 'literary' research text that uses conventional sociological forms together with images, poetry and personal stories. I use anthropological and geographical theoretical constructs to look at the changing material, economic, cultural and social landscapes and the mosaic of inequalities in the city of Adelaide. I suggest that this is not a simple binary polarisation, although large numbers of people are similarly positioned by de-industrialisation and the diminishing social wage. After examining the literature on poverty in Australia, I am eventually prepared to call this space class, understanding that this is a sociological metaphor. Through a theorisation of each school as a 'place' within a specific neighbourhood, I look at the similarities and differences across sites. I suggest that 'disadvantaged schools' are similarly positioned as sites for the mediation of social inequalities, and that this can be readily seen in the time consuming 'housework' of discipline and welfare. I indicate how each school is differently able to 'do more with less', because of their unique neighbourhood and its narratives, knowledges, histories, teleologies and people. I show that the common coercive regimes of market devolution, new public management and the 'distributive curriculum' frame the work of teachers, students and administrators in ways that are not conducive to 'doing justice', despite the policy rhetoric of equity and community. I provide evidence that the neoliberal imaginary of context free schooling enshrined in effective schools literatures is Utopian and irrational. I argue that the capacity of the school to 'generate context' is always paradoxically dependent on 'context derived'. I discuss the notion of 'doing justice' and the benefits of 'disadvantaged schools' having a local set of principles that guide their decisions and actions and provide evidence that the school administrator's understandings of 'doing justice' are important. I also suggest that, despite being increasingly isolated and hindered by policy directions, the majority of the sixteen schools continue to work for and with principles of justice and equity, drawing on a range of emotional and intellectual resources and deep, longstanding commitments. I conclude by speculating on the kinds of policy and research agendas that might take account of both the commonalities and differences amongst 'disadvantaged schools', and what might be included in a comprehensive and systematic approach to 'doing justice'.

Systemic administration of interleukin-1β activates select populations of central amygdala afferents

The central nucleus of the amygdala (CeA) is activated robustly by an immune challenge such as the systemic administration of the proinflammatory cytokine interleukin-1β (IL-1β). Because IL-1β is not believed to cross the blood-brain barrier in any significant amount, it is likely that IL-1β elicits CeA cell recruitment by means of activation of afferents to the CeA. However, although many studies have investigated the origins of afferent inputs to the CeA, we do not know which of these also respond to IL-1β. Therefore, to identify candidate neurons responsible for the recruitment of CeA cells by an immune challenge, we iontophoretically deposited a retrograde tracer, cholera toxin b-subunit (CTb), into the CeA of rats 7 days before systemic delivery of IL-1β (1 μg/kg, i.a.). By using combined immunohistochemistry, we then quantified the number of Fos-positive CTb cells in six major regions known to innervate the CeA. These included the medial prefrontal cortex, paraventricular thalamus (PVT), ventral tegmental area, parabrachial nucleus (PB), nucleus tractus solitarius, and ventrolateral medulla. Our results show that after deposit of CTb into the CeA, the majority of double-labeled cells were located in the PB and the PVT, suggesting that CeA cell activation by systemic IL-1β is likely to arise predominantly from cell bodies located in these regions. These findings may have significant implications in determining the central pathways involved in generating acute central responses to a systemic immune challenge.

Internet administration of three commonly used questionnaires in panic research : equivalence to paper administration in Australian and Swedish samples of people with panic disorder

This study assessed the degree of equivalence between paper and Internet administration of three measures of panic and agoraphobia-related cognition and behavior: Body Sensations Questionnaire (BSQ), Agoraphobic Cognitions Questionnaire (ACQ), and Mobility Inventory (MI). Participants were 110 people with panic disorder who had registered for an Internet-based treatment program in Sweden (n = 54) or Australia (n = 56). Participants were randomly assigned to complete the questionnaires via the differing administration formats in a counterbalanced order. Results showed broadly equivalent psychometric properties across administrations, with strong significant intraclass correlations between them, and comparable Cronbach's alpha coefficients. A significant mean difference between administration formats was found for the BSQ only. In contrast to previous research, Internet administration did not generate higher scores than paper administration. No effect was found for order of administration. The findings suggest that each questionnaire can be validly administered via the Internet and used with confidence.

Construct validity and reliability of the single checking administration of medications scale

Research indicates that single checking of medications is as safe as double checking; however, many nurses are averse to independently checking medications. To assist with the introduction and use of single checking, a measure of nurses' attitudes, the thirteen-item Single Checking Administration of Medications Scale (SCAMS) was developed. We examined the psychometric properties of the SCAMS. Secondary analyses were conducted on data collected from 503 nurses across a large Australian health-care service. Analyses using exploratory and confirmatory factor analyses supported by structural equation modelling resulted in a valid twelve-item SCAMS containing two reliable subscales, the nine-item Attitudes towards single checking and three-item Advantages of single checking subscales. The SCAMS is recommended as a valid and reliable measure for monitoring nurses' attitudes to single checking prior to introducing single checking medications and after its implementation.

The effect of oral administration of iron saturated-bovine lactoferrin encapsulated chitosan-nanocarriers on osteoarthritis

In this study, the therapeutic potentials of 100% iron saturated-bovine lactoferrin encapsulated in alginate-chitosan polymeric nanocarriers (AEC-CP-Fe-bLf-NCs) were examined in in vitro inflammatory OA model and in collagen-induced arthritis (CIA) mice. Oral administration of nanocarriers in mice were non-toxic and significantly induced disease modifying activity by reducing joint inflammation and downregulating the expression of catabolic genes, IL-1β, NO, JNK and MAPK. In addition, up-regulation of type II collagen, aggrecan and inflammation depleted iron and calcium metabolisms via inhibition of miRNA of iron transporting receptors was shown in AEC-CP-Fe-bLf-NCs treated mice.

A social justice scrutiny of the seating service experiences: what can we learn?

The paper presents the social justice findings from a study into the Australian  (wheelchair) seating service experience. As this study explored the insider's perspective, three participants' examples are shared (in the presentation) to demonstrate the benefits accorded to equality, equity and equal opportunity and the injustices experienced when denied;
- Brian* (pseudonym) a young Australian whose two accessories for his power chair changed his life.
- Donna* whose adult son was provided a heavy standard manual wheelchair instead of the power chair requested.
- Vince* a young self-employed businessman whose newly provided robust power chair is crimping his productivity.

Testing the validity, reliability and utility of the Self-Administration of Medication (SAM) tool in patients undergoing rehabilitation.

Determination of patients' ability to self-administer medications in the hospital has largely been determined using the subjective judgment of health professionals.

Acute mood but not cognitive improvements following administration of a single multivitamin and mineral supplement in healthy women aged 50 and above : a randomised controlled trial

A number of randomised controlled trials have indicated that multivitamin/mineral supplementation for a period of 4 weeks or greater can enhance mood and cognition. To date, no studies have investigated whether a single multivitamin dose can benefit mental function in older adults. This study investigated the acute effects of a single multivitamin and mineral and herbal (MVMH) supplement versus placebo on self ratings of mood and the performance of an effortful computerised cognitive battery in a sample of 76 healthy women aged 50-75 years. Mood was assessed using the depression anxiety stress scale (DASS), state trait anxiety inventory-state anxiety scale and visual analogue scales (VAS). Mood was rated at 1 h post supplementation and again after the competition of the cognitive assessments at 2 h post supplementation. It was demonstrated that the MVMH supplement improved overall DASS mood ratings; however, the most prominent effects appeared to be a reduction in ratings of perceived mental stress. These findings were confirmed using visual analogue scales, with these measures also demonstrating MVMH-related increased ratings of calmness. There were no benefits of the MVMH to mood ratings of depression and performance was not enhanced on the cognitive battery. Supplementation with a single multivitamin, mineral and herbal supplement reduces stress several hours after intake in healthy older people.

Oral administration of iron-saturated bovine lactoferrin-loaded ceramic nanocapsules for breast cancer therapy and influence on iron and calcium metabolism

We determined the anticancer efficacy and internalization mechanism of our polymeric-ceramic nanoparticle system (calcium phosphate nanocores, enclosed in biodegradable polymers chitosan and alginate nanocapsules/nanocarriers [ACSC NCs]) loaded with iron-saturated bovine lactoferrin (Fe-bLf) in a breast cancer xenograft model. ACSC-Fe-bLf NCs with an overall size of 322±27.2 nm were synthesized. In vitro internalization and anticancer efficacy were evaluated in the MDA-MB-231 cells using multicellular tumor spheroids, CyQUANT and MTT assays. These NCs were orally delivered in a breast cancer xenograft mice model, and their internalization, cytotoxicity, biodistribution, and anticancer efficacy were evaluated. Chitosan-coated calcium phosphate Fe-bLf NCs effectively (59%, P≤0.005) internalized in a 1-hour period using clathrin-mediated endocytosis (P≤0.05) and energy-mediated pathways (P≤0.05) for internalization; 3.3 mg/mL of ACSC-Fe-bLf NCs completely disintegrated (~130-fold reduction, P≤0.0005) the tumor spheroids in 72 hours and 96 hours. The IC50 values determined for ACSC-Fe-bLf NCs were 1.69 mg/mL at 10 hours and 1.62 mg/mL after 20 hours. We found that Fe-bLf-NCs effectively (P≤0.05) decreased the tumor size (4.8-fold) compared to the void NCs diet and prevented tumor recurrence when compared to intraperitoneal injection of Taxol and Doxorubicin. Receptor gene expression and micro-RNA analysis confirmed upregulation of low-density lipoprotein receptor and transferrin receptor (liver, intestine, and brain). Several micro-RNAs responsible for iron metabolism upregulated with NCs were identified. Taken together, orally delivered Fe-bLf NCs offer enhanced antitumor activity in breast cancer by internalizing via low-density lipoprotein receptor and transferrin receptor and regulating the micro-RNA expression. These NCs also restored the body iron and calcium levels and increased the hematologic counts.
