Repurposing literacy: the uses of Richard Hoggart for creative education

After 50 years, what are the implications of Uses of Literacy for educational modernisation, in the light of subsequent changes from 'read only' literacy to 'read-write' uses of multimedia? This chapter argues that a broad extension of popular literacy via consumer-created digital content offers not only emancipationist potential in line with Hoggart's own project, but also economic benefits via the dynamics of creative innovation. Multimedia 'popular entertainments' pose a challenge to formal education, but not in the way that Hoggart feared. Instead of producing 'tamed helots,' commercial culture may be outpacing formal schooling in promoting creative digital literacy via entrepreneurial and distributed learning. It may indeed be that those in need of a creative make-over are not teenagers but teachers

Unlocking the History of the Australasian Kuo Min Tang 1911-2013

This book is the story of an association that began as a local club and became the regional headquarters of a transnational political party. It is based on extensive research and large collections of photographs and documents held in Australian KMT archives. Oral history interviews have supplemented this rich documentary record

Effects of flanking sequences and cellular context on subcellular behavior and pathology of mutant HTT

Huntington’s disease (HD) is caused by an expansion of a poly glutamine (polyQ) stretch in the huntingtin protein (HTT) that is necessary to cause pathology and formation of HTT aggregates. Here we ask whether expanded polyQ is sufficient to cause pathology and aggregate formation. By addressing the sufficiency question, one can identify cellular processes and structural parameters that influence HD pathology and HTT subcellular behavior (i.e. aggregation state and subcellular location). Using Drosophila, we compare the effects of expressing mutant full-length human HTT (fl-mHTT) to the effects of mutant human HTTexon1 and to two commonly used synthetic fragments, HTT171 and shortstop (HTT118). Expanded polyQ alone is not sufficient to cause inclusion formation since full-length HTT and HTTex1 with expanded polyQ are both toxic although full-length HTT remains diffuse while HTTex1 forms inclusions. Further, inclusions are not sufficient to cause pathology since HTT171-120Q forms inclusions but is benign and co-expression of HTT171-120Q with non-aggregating pathogenic fl-mHTT recruits fl-mHTT to aggregates and rescues its pathogenicity. Additionally, the influence of sequences outside the expanded polyQ domain is revealed by finding that small modifications to the HTT118 or HTT171 fragments can dramatically alter their subcellular behavior and pathogenicity. Finally, mutant HTT subcellular behavior is strongly modified by different cell and tissue environments (e.g. fl-mHTT appears as diffuse nuclear in one tissue and diffuse cytoplasmic in another but toxic in both). These observations underscore the importance of cellular and structural context for the interpretation and comparison of experiments using different fragments and tissues to report the effects of expanded polyQ

Temporal dissociation of phencyclidine: Induced locomotor and social alterations in rats using an automated homecage monitoring system – implications for the 3Rs and preclinical drug discovery

Background: Rodent behavioural assays are widely used to delineate the mechanisms of psychiatric disorders and predict the efficacy of drug candidates. Conventional behavioural paradigms are restricted to short time windows and involve transferring animals from the homecage to unfamiliar apparatus which induces stress. Additionally, factors including environmental perturbations, handling and the presence of an experimenter can impact behaviour and confound data interpretation. To improve welfare and reproducibility these issues must be resolved. Automated homecage monitoring offers a more ethologically relevant approach with reduced experimenter bias. Aim: To evaluate the effectiveness of an automated homecage system at detecting locomotor and social alterations induced by phencyclidine (PCP) in group-housed rats. PCP is an NMDA receptor antagonist commonly utilised to model aspects of schizophrenia. Methods: Rats housed in groups of 3 were implanted with radio frequency identification (RFID) tags. Each homecage was placed over a RFID reader baseplate for the automated monitoring of the social and locomotor activity of each individual rat. For all rats, we acquired homecage data for 24 h following administration of both saline and PCP (2.5 mg/kg). Results: PCP resulted in significantly increased distance travelled from 15 to 60 min post injection. Furthermore, PCP significantly enhanced time spent isolated from cage-mates and this asociality lasted from 60 to 105 min post treatment. Conclusions: Unlike conventional assays, in-cage monitoring captures the temporal duration of drug effects on multiple behaviours in the same group of animals. This approach could benefit psychiatric preclinical drug discovery though improved welfare and increased between-laboratory replicability

T2DM Clinical Decision Support System: Comprehensive Patient Care

We report on the current state of type 2 diabetes clinical decision support systems (CDSS), identify gaps that contribute to the lack of CDSS success, and apply lessons learned from practice for developing and implementing a localized diabetes CDSS. A survey of the literature reveals mixed findings regarding the efficacy of the CDSS; they do not include patient-rich information – the patient experience data in the electronic health records. We believe that diabetes care can improve by guiding clinical decisions using published evidence, patient preferences, and clinical data augmented by the local patient experience and social determinants of health using natural language processing and machine learning techniques

Disruption of the Zdhhc9 intellectual disability gene leads to behavioural abnormalities in a mouse

Protein S-acylation is a widespread post-translational modification that regulates the trafficking and function of a diverse array of proteins. This modification is catalysed by a family of twenty-three zDHHC enzymes that exhibit both specific and overlapping substrate interactions. Mutations in the gene encoding zDHHC9 cause mild-to-moderate intellectual disability, seizures, speech and language impairment, hypoplasia of the corpus callosum and reduced volume of sub-cortical structures. In this study, we have undertaken behavioural phenotyping, magnetic resonance imaging (MRI) and isolation of S-acylated proteins to investigate the effect of disruption of the Zdhhc9 gene in mice in a C57BL/6 genetic background. Zdhhc9 mutant male mice exhibit a range of abnormalities compared with their wild-type littermates: altered behaviour in the open-field test, elevated plus maze and acoustic startle test that is consistent with a reduced anxiety level; a reduced hang time in the hanging wire test that suggests underlying hypotonia but which may also be linked to reduced anxiety; deficits in the Morris water maze test of hippocampal-dependent spatial learning and memory; and a 36% reduction in corpus callosum volume revealed by MRI. Surprisingly, membrane association and S-acylation of H-Ras was not disrupted in either whole brain or hippocampus of Zdhhc9 mutant mice, suggesting that other substrates of this enzyme are linked to the observed changes. Overall, this study highlights a key role for zDHHC9 in brain development and behaviour, and supports the utility of the Zdhhc9 mutant mouse line to investigate molecular and cellular changes linked to intellectual disability and other deficits in the human population

Alpha3/alpha2 power ratios relate to performance on a virtual reality shopping task in ageing adults

Background: Aspects of cognitive function decline with age. This phenomenon is referred to as age-related cognitive decline (ARCD). Improving the understanding of these changes that occur as part of the ageing process can serve to enhance the detection of the more incapacitating neurodegenerative disorders such as Alzheimer’s disease (AD). In this study, we employ novel methods to assess ARCD by exploring the utility of the alpha3/alpha2 electroencephalogram (EEG) power ratio – a marker of AD, and a novel virtual reality (VR) functional cognition task – VStore, in discriminating between young and ageing healthy adults. Materials and methods: Twenty young individuals aged 20–30, and 20 older adults aged 60–70 took part in the study. Participants underwent resting-state EEG and completed VStore and the Cogstate Computerised Cognitive Battery. The difference in alpha3/alpha2 power ratios between the age groups was tested using t-test. In addition, the discriminatory accuracy of VStore and Cogstate were compared using logistic regression and overlying receiver operating characteristic (ROC) curves. Youden’s J statistic was used to establish the optimal threshold for sensitivity and specificity and model performance was evaluated with the DeLong’s test. Finally, alpha3/alpha2 power ratios were correlated with VStote and Cogstate performance. Results: The difference in alpha3/alpha2 power ratios between age cohorts was not statistically significant. On the other hand, VStore discriminated between age groups with high sensitivity (94%) and specificity (95%) The Cogstate Pre-clinical Alzheimer’s Battery achieved a sensitivity of 89% and specificity of 60%, and Cogstate Composite Score achieved a sensitivity of 83% and specificity of 85%. The differences between the discriminatory accuracy of VStore and Cogstate models were statistically significant. Finally, high alpha3/alpha2 power ratios correlated strongly with VStore (r = 0.73), the Cogstate Pre-clinical Alzheimer’s Battery (r = -0.67), and Cogstate Composite Score (r = -0.76). Conclusion: While we did not find evidence that the alpha3/alpha2 power ratio is elevated in healthy ageing individuals compared to young individuals, we demonstrated that VStore can classify age cohorts with high accuracy, supporting its utility in the assessment of ARCD. In addition, we found preliminary evidence that elevated alpha3/alpha2 power ratio may be linked to lower cognitive performance

Preconception Health Knowledge among Undergraduate Women

Preconception health is a woman’s health before she becomes pregnant. It means knowing and understanding how preexisting health conditions and risk factors could affect a woman or her unborn child if she becomes pregnant (Office on Women’s Health, 2010). This study examined undergraduate students’ knowledge of recommended preconception health practices. A paper survey was distributed to general education classes in health, sociology, and family consumer science. This 33-item survey assessed demographics, barriers to practicing recommended preconception health behaviors, and knowledge of preconception health practices. Analyses included frequencies, independent t-test, and ANOVA. Respondents had a mean score of 42.85 (2.68) on the knowledge section of the survey; indicating that respondents had a high level of knowledge regarding preconception health practices and information. Respondents’ knowledge scores were statistically correlated with their preconception health practices and behaviors (r=.176, p=.000). As knowledge scores increased, preconception health practice and behaviors scores also increased. When analyzing participants’ current health behaviors as they relate to preconception health, it was found that most students are engaging in healthy behaviors
