    Composing has been a significant and assessed part of music in the classroom since its introduction into the English National Curriculum in 1988. However, there is very little research into how the assessment of composing influences teaching and learning practices. Within a time of great educational change and uncertainty for music education, this research seeks to uncover complexities within teaching and assessing composing at Key Stage 4 and Key Stage 5. To investigate this under-researched area, mixed methodology approaches were used. Two surveys were conducted to gather breadth of teachers’ experiences of the assessment and nine telephone interviews with selected participants from the survey were also conducted. Five case studies allowed for in-depth data collection from diverse school settings from teachers as well as students. Case study data were obtained through interviews, focus groups and field observations. As the research sought to capture multiple perspectives, interviews with five composer-educators were also included. Data from participants were analysed through thematic and grounded theory approaches, as well as theorised using Engeström’s (2001) culturalhistorical activity theory and Bourdieu’s (1984) notions of field, capital and habitus. Several contributions to knowledge are presented and discussed such as the significant concerns regarding reliability, subjectivity and bias in the assessment of composing at KS4 and KS5, along with questions regarding validity and real-world usefulness of the teaching and examinations. Due to high accountability cultures many teachers felt they had to alter their teaching to ensure their students passed the examinations. The study uncovered layers of powers, myths and mechanisms used to keep control, which in turn created internal conflict in teachers. Although this study found discontent and conflict, teachers and students were also complicit, not feeling able to openly contest the current systems in place. This exploratory study gives an indepth overview into the complexities of assessing and teaching composing at KS4 and KS5 outlining the challenges and pressures teachers and students face

    Analysis of putative resistance gene loci in UK field populations of Haemonchus contortus after six years of macrocyclic lactone use

    Sheep farmers in the UK rely on strategic anthelmintic use to treat and control gastrointestinal roundworms in their flocks. However, resistance to these drugs is now widespread and threatens the sustainability of sheep production. The mechanisms underlying resistance to the most commonly used class, the macrocyclic lactones, are not known and sensitive diagnostic tools based on molecular markers are not currently available. This prohibits accurate surveillance of resistance or assessment of strategies aimed at controlling its spread. In this study, we examined four UK field populations of Haemonchus contortus, differing in macrocyclic lactone treatment history, for evidence of selection at ‘candidate gene’ loci identified as determining macrocyclic lactone resistance in previously published research. Individual worms were genotyped at Hc-lgc-37, Hc-glc-5, Hc-avr-14 and Hc-dyf-7, and four microsatellite loci. High levels of polymorphism were identified at the first three candidate gene loci with remarkably little polymorphism at Hc-dyf-7. While some between-population comparisons of individual farms with and without long-term macrocyclic lactone use identified statistically significant differences in allele frequency and/or fixation index at the Hc-lgc-37, Hc-glc-5 or Hc-avr-14 loci, we found no consistent evidence of selection in other equivalent comparisons. While it is possible that different mechanisms are important in different populations or that resistance may be conferred by small changes at multiple loci, our findings suggest that these are unlikely to be major loci conferring macrocyclic lactone resistance on UK farms or suitable for diagnostic marker development. More powerful approaches, using genome-wide or whole genome sequencing, may be required to define macrocyclic lactone resistance loci in such genetically variable populations

    Despite music being a statutory subject in the National Curriculum since 1992, the value and place of music and the arts in schools has been in flux with recent policy changes influencing if and how music is being taught in schools. There is concern that music is not being delivered in all primary schools in England, meaning some children are being denied the music education they are entitled to. Another important aspect of music education in primary schools is that many teachers lack confidence teaching music as a classroom subject. This research investigated BCU’s trainee primary teachers’ experiences of music education in their placement schools. This research sought to better understand how schools are interpreting governmental music education policy by investigating the lived realities of trainee primary music teachers during their school placements. Perspectives and experiences of classroom music teaching in primary schools were collected from 126 BCU trainee primary teachers in the School of Education and Social Work, drawing from a diverse range of primary school contexts. Participants were asked to share their experiences via an online survey. Five key findings were drawn from the research data: (1) Trainee teachers did not have equal opportunities to teach music, (2) Confidence in music teaching ability varied, (3) Instrumental teaching and learning was prioritised, (4) Primary teachers need more support with music teaching during and beyond their training to help them develop agency and their own music teaching practice, (5) Trainee teachers care about music education, but they are concerned about the status of music as a subject in primary schools

    Characterisation of infection associated microRNA and protein cargo in extracellular vesicles of Theileria annulata infected leukocytes

    The protozoan parasites, Theileria annulata and T. parva are unique amongst intracellular eukaryotic pathogens as they induce a transformation‐like phenotype in their bovine host cell. T. annulata causes tropical theileriosis, which is frequently fatal, with infected leukocytes becoming metastatic and forming foci in multiple organs resulting in destruction of the lymphoid system. Exosomes, a sub‐set of extracellular vesicles (EV), are critical in metastatic progression in many cancers. Here we characterised the cargo of EV from a control bovine lymphosarcoma cell line (BL20) and BL20 infected with T. annulata (TBL20) by comparative mass spectrometry and miRNA profiling (data available via ProteomeXchange, identifier PXD010713 and NCBI GEO, accession number GSE118456, respectively). Ingenuity Pathway Analysis that many infection‐associated proteins essential to migration and extracellular matrix digestion were upregulated in EV from TBL20 cells compared to BL20 controls. An altered repertoire of host miRNA, many with known roles in tumor and/or infection biology was also observed. Focusing on the tumor suppressor miRNA, bta‐miR‐181a and bta‐miR‐181b, we identified putative mRNA targets and confirmed the interaction of bta‐miR181a with icam‐1. We propose that EV and their miRNA cargo play an important role in the manipulation of the host cell phenotype and the pathobiology of Theileria infection

    Since its inception as a partnership project between Sound and Music and sound Scotland, Go Compose has developed to be a national network of workshops, programmes and events giving young people opportunities to make and showcase their own music and learn from professionals. Aimed at young people who would like to try composing, or who know they enjoy it and would like to learn more, we work with everyone from music education hubs to festivals across the UK to offer opportunities.In this iteration of Go Compose, generously funded by Youth Music, Sound and Music focused on composing for and by young people who face additional barriers to engagement including disabling barriers, not being in education, employment or training (NEET) and being a girl in a music technology environment. Activity was delivered by three wonderful partners, Community Music, Drake Music and University of Huddersfield (working with Yorkshire Sound Women Network)

    Increased expression of a microRNA correlates with anthelmintic resistance in parasitic nematodes

    Resistance to anthelmintic drugs is a major problem in the global fight against parasitic nematodes infecting humans and animals. While previous studies have identified mutations in drug target genes in resistant parasites, changes in the expression levels of both targets and transporters have also been reported. The mechanisms underlying these changes in gene expression are unresolved. Here, we take a novel approach to this problem by investigating the role of small regulatory RNAs in drug resistant strains of the important parasite Haemonchus contortus. microRNAs (miRNAs) are small (22 nt) non-coding RNAs that regulate gene expression by binding predominantly to the 3′ UTR of mRNAs. Changes in miRNA expression have been implicated in drug resistance in a variety of tumor cells. In this study, we focused on two geographically distinct ivermectin resistant strains of H. contortus and two lines generated by multiple rounds of backcrossing between susceptible and resistant parents, with ivermectin selection. All four resistant strains showed significantly increased expression of a single miRNA, hco-miR-9551, compared to the susceptible strain. This same miRNA is also upregulated in a multi-drug-resistant strain of the related nematode Teladorsagia circumcincta. hco-miR-9551 is enriched in female worms, is likely to be located on the X chromosome and is restricted to clade V parasitic nematodes. Genes containing predicted binding sites for hco-miR-9551 were identified computationally and refined based on differential expression in a transcriptomic dataset prepared from the same drug resistant and susceptible strains. This analysis identified three putative target mRNAs, one of which, a CHAC domain containing protein, is located in a region of the H. contortus genome introgressed from the resistant parent. hco-miR-9551 was shown to interact with the 3′ UTR of this gene by dual luciferase assay. This study is the first to suggest a role for miRNAs and the genes they regulate in drug resistant parasitic nematodes. miR-9551 also has potential as a biomarker of resistance in different nematode species

    A repurposing strategy for Hsp90 inhibitors demonstrates their potency against filarial nematodes

    Novel drugs are required for the elimination of infections caused by filarial worms, as most commonly used drugs largely target the microfilariae or first stage larvae of these infections. Previous studies, conducted in vitro, have shown that inhibition of Hsp90 kills adult Brugia pahangi. As numerous small molecule inhibitors of Hsp90 have been developed for use in cancer chemotherapy, we tested the activity of several novel Hsp90 inhibitors in a fluorescence polarization assay and against microfilariae and adult worms of Brugia in vitro. The results from all three assays correlated reasonably well and one particular compound, NVP-AUY922, was shown to be particularly active, inhibiting Mf output from female worms at concentrations as low as 5.0 nanomolar after 6 days exposure to drug. NVP-AUY922 was also active on adult worms after a short 24 h exposure to drug. Based on these in vitro data, NVP-AUY922 was tested in vivo in a mouse model and was shown to significantly reduce the recovery of both adult worms and microfilariae. These studies provide proof of principle that the repurposing of currently available Hsp90 inhibitors may have potential for the development of novel agents with macrofilaricidal properties

    Profiling microRNAs through development of the parasitic nematode Haemonchus identifies nematode-specific miRNAs that suppress larval development

    Get PDF
    Parasitic nematodes transition between dramatically different free-living and parasitic stages, with correctly timed development and migration crucial to successful completion of their lifecycle. However little is known of the mechanisms controlling these transitions. microRNAs (miRNAs) negatively regulate gene expression post-transcriptionally and regulate development of diverse organisms. Here we used microarrays to determine the expression profile of miRNAs through development and in gut tissue of the pathogenic nematode Haemonchus contortus. Two miRNAs, mir-228 and mir-235, were enriched in infective L3 larvae, an arrested stage analogous to Caenorhabditis elegans dauer larvae. We hypothesized that these miRNAs may suppress development and maintain arrest. Consistent with this, inhibitors of these miRNAs promoted H. contortus development from L3 to L4 stage, while genetic deletion of C. elegans homologous miRNAs reduced dauer arrest. Epistasis studies with C. elegans daf-2 mutants showed that mir-228 and mir-235 synergise with FOXO transcription factor DAF-16 in the insulin signaling pathway. Target prediction suggests that these miRNAs suppress metabolic and transcription factor activity required for development. Our results provide novel insight into the expression and functions of specific miRNAs in regulating nematode development and identify miRNAs and their target genes as potential therapeutic targets to limit parasite survival within the host

    Assay strategies for the discovery and validation of therapeutics targeting <i>Brugia pahangi</i> Hsp90

    The chemotherapy of lymphatic filariasis relies upon drugs such as diethylcarbamazine and ivermectin that largely target the microfilarial stages of the parasite, necessitating continued treatment over the long reproductive life span of the adult worm. The identification of compounds that target adult worms has been a long-term goal of WHO. Here we describe a fluorescence polarization assay for the identification of compounds that target Hsp90 in adult filarial worms. The assay was originally developed to identify inhibitors of Hsp90 in tumor cells, and relies upon the ability of small molecules to inhibit the binding of fluorescently labelled geldanamycin to Hsp90. We demonstrate that the assay works well with soluble extracts of Brugia, while extracts of the free-living nematode C. elegans fail to bind the probe, in agreement with data from other experiments. The assay was validated using known inhibitors of Hsp90 that compete with geldanamycin for binding to Hsp90, including members of the synthetic purine-scaffold series of compounds. The efficacy of some of these compounds against adult worms was confirmed in vitro. Moreover, the assay is sufficiently sensitive to differentiate between binding of purine-scaffold compounds to human and Brugia Hsp90. The assay is suitable for high-throughput screening and provides the first example of a format with the potential to identify novel inhibitors of Hsp90 in filarial worms and in other parasitic species where Hsp90 may be a target

    Genomic and transcriptomic variation defines the chromosome-scale assembly of Haemonchus contortus, a model gastrointestinal worm

    Get PDF
    International audienceHaemonchus contortus is a globally distributed and economically important gastrointestinal pathogen of small ruminants and has become a key nematode model for studying anthelmintic resistance and other parasite-specific traits among a wider group of parasites including major human pathogens. Here, we report using PacBio long-read and OpGen and 10X Genomics long-molecule methods to generate a highly contiguous 283.4 Mbp chromosome-scale genome assembly including a resolved sex chromosome for the MHco3(ISE).N1 isolate. We show a remarkable pattern of conservation of chromosome content with Caenorhabditis elegans, but almost no conservation of gene order. Short and long-read transcriptome sequencing allowed us to define coordinated transcriptional regulation throughout the parasite’s life cycle and refine our understanding of cis- and trans-splicing. Finally, we provide a comprehensive picture of chromosome-wide genetic diversity both within a single isolate and globally. These data provide a high-quality comparison for understanding the evolution and genomics of Caenorhabditis and other nematodes and extend the experimental tractability of this model parasitic nematode in understanding helminth biology, drug discovery and vaccine development, as well as important adaptive traits such as drug resistance
