    Civil society organisations and Target 4.7 of the SDGs: towards intersectionality for promoting a more just and sustainable world

    Target 4.7 of the United Nations Sustainable Development Goals can provide an opportunity for a more transformative approach to education. To consider this requires a new approach to learning that moves beyond subjects and disciplines to recognise intersectionality as being central to providing a radical rethinking of the purpose of education. Evidence from initiatives by civil society organisations in England shows that there are examples of these practices. At an international level, the Dublin Declaration on Global Education to 2050 provides an additional boost to calling for a major transformation in education

    Close to practice research as a means of rethinking elements of student–teacher's classroom practice

    This article explores a form of classroom inquiry linked to postgraduate primary student–teachers’ education, whilst on practicum in England. The inquiry model is congruent with Stenhouse's’ notions of ‘teachers as researchers’ undertaking ‘systematic’ inquiry in a ‘naturalistic’ environment. Feldman further develops Stenhouse's conception into a definition of action research, where teachers come to a better understanding of their practice. The inquiry bases itself on the central tenants of close to practice (CtP), which is defined as research that: focuses on issues defined by practitioners as relevant to their practice and involves collaboration between people whose main expertise is research, practice, or both. As teacher educators, we evaluated the potential of CtP inquiry, by undertaking a critical discourse analysis (CDA) of sixteen student–teacher research reports. CDA revealed that several socio-cognitive processes took place as a result of, student–teachers engaging in CtP research, including explorations of identity, beliefs and values and negotiation of power relationships and structures. Further analysis provided insights into Stenhouses' conceptualisation, firstly, how student–teachers committed to developing their understanding of the curriculum with respect to teaching design. Secondly, the findings resonate with student–teachers rejecting acting as ‘docile agents’ within existing structures and developing ‘pathways to emancipation and autonomy’. Thirdly, testimony revealed that student–teachers valued this mode of learning and developed critical attitudes to educational research. This study has clear implications for the design of initial teacher education programs and the continued professional development of teachers in England and potentially further afield

    The Use of ROC Analysis for the Qualitative Prediction of Human Oral Bioavailability from Animal Data

    PURPOSE: To develop and evaluate a tool for the qualitative prediction of human oral bioavailability (F(human)) from animal oral bioavailability (F(animal)) data employing ROC analysis and to identify the optimal thresholds for such predictions. METHODS: A dataset of 184 compounds with known F(human) and F(animal) in at least one species (mouse, rat, dog and non-human primates (NHP)) was employed. A binary classification model for F(human) was built by setting a threshold for high/low F(human) at 50%. The thresholds for high/low F(animal) were varied from 0 to 100 to generate the ROC curves. Optimal thresholds were derived from ‘cost analysis’ and the outcomes with respect to false negative and false positive predictions were analyzed against the BDDCS class distributions. RESULTS: We successfully built ROC curves for the combined dataset and per individual species. Optimal F(animal) thresholds were found to be 67% (mouse), 22% (rat), 58% (dog), 35% (NHP) and 47% (combined dataset). No significant trends were observed when sub-categorizing the outcomes by the BDDCS. CONCLUSIONS: F(animal) can predict high/low F(human) with adequate sensitivity and specificity. This methodology and associated thresholds can be employed as part of decisions related to planning necessary studies during development of new drug candidates and lead selection.

    Targeted knock-down of miR21 primary transcripts using snoMEN vectors induces apoptosis in human cancer cell lines

    We have previously reported an antisense technology, 'snoMEN vectors', for targeted knock-down of protein coding mRNAs using human snoRNAs manipulated to contain short regions of sequence complementarity with the mRNA target. Here we characterise the use of snoMEN vectors to target the knock-down of micro RNA primary transcripts. We document the specific knock-down of miR21 in HeLa cells using plasmid vectors expressing miR21-targeted snoMEN RNAs and show this induces apoptosis. Knock-down is dependent on the presence of complementary sequences in the snoMEN vector and the induction of apoptosis can be suppressed by over-expression of miR21. Furthermore, we have also developed lentiviral vectors for delivery of snoMEN RNAs and show this increases the efficiency of vector transduction in many human cell lines that are difficult to transfect with plasmid vectors. Transduction of lentiviral vectors expressing snoMEN targeted to pri-miR21 induces apoptosis in human lung adenocarcinoma cells, which express high levels of miR21, but not in human primary cells. We show that snoMEN-mediated suppression of miRNA expression is prevented by siRNA knock-down of Ago2, but not by knock-down of Ago1 or Upf1. snoMEN RNAs colocalise with Ago2 in cell nuclei and nucleoli and can be co-immunoprecipitated from nuclear extracts by antibodies specific for Ago2

    The Gestational Diabetes Management System (GooDMomS): development, feasibility and lessons learned from a patient-informed, web-based pregnancy and postpartum lifestyle intervention

    Abstract Background Gestational diabetes mellitus (GDM) contributes to the epidemic of diabetes and obesity in mothers and their offspring. The primary objective of this pilot study was to: 1) refine the GDM Management System (GooDMomS), a web-based pregnancy and postpartum behavioral intervention and 2) assess the feasibility of the intervention. Methods In phase 1, ten semi-structured interviews were conducted with women experiencing current or recent GDM mellitus GDM to garner pilot data on the web based intervention interface, content, and to solicit recommendations from women about refinements to enhance the GooDMomS intervention site. Interviews were audiotaped, transcribed and independently reviewed to identify major themes with Atlas.ti v7.0. In phase 2, a single-arm feasibility study was conducted and 23 participants were enrolled in the GooDMomS program. Participants received web lessons, self-tracking of weight and glucose, automated feedback and access to a message board for peer support. The primary outcome was feasibility, including recruitment and retention and acceptability. Secondary outcomes included the proportion of women whose gestational weight gain (GWG) was within the Institute of Medicine (IOM) guidelines and who were able to return to their pre-pregnancy weight after delivery. Results Comments from semi-structured interviews focused on: 1) usability of the on-line self-monitoring diary and tracking system, 2) access to a safe, reliable social network for peer support and 3) ability of prenatal clinicians to access the on-line diary for clinical management. Overall, 21 (91 %) completed the pregnancy phase. 15/21 (71 %) of participants were within the Institute of Medicine (IOM) guidelines for GWG. Sixteen (70 %) completed the postpartum phase. 7/16 (43 %) and 9/16 (56 %) of participants returned to their pre-pregnancy weight at 6 and 30 weeks postpartum, respectively. Conclusions This study documents the feasibility of the GooDMomS program. The results can have implications for web technology in perinatal care and inform the current care paradigm for women with GDM. Findings are supportive of further research with recruitment of a larger sample of participants and comparison of the outcomes with the intervention and standard care. Trial registration The study was registered at ClinicalTrials.gov on May 15, 2012 under protocol no. NCT01600534
