Ballads, songs and snatches: The appropriation of and responses to folk song and popular music culture in the nineteenth century

Ballads, Songs and Snatches demonstrates how allusion to folk song and some aspects of popular musical culture were absorbed into the polyphony of discourses in the realist prose of the nineteenth century, and explores the implications of the various transformations that occurred during this process, with an emphasis on the representation of the labouring classes. Wide and deep acquaintance with folk tradition is shown to account for richly dense literary textuaJity, especially in Scott and Hardy, even where they mediate their knowledge tactically. Lack of that knowledge is consonant with weakness in such representation. The sources used by each writer are identified as accurately as possible. The book is necessarily interdisciplinary, bringing together literary and folk song study and scholarship. It defines a new category for discourse analysis, the 'false intertext', i.e. supposed allusions to folk song or other texts actually composed by the prose writers themselves. It investigates the effects within the literary texts both of these false intertexts and of the inclusion of material so heavily mediated as substantially to misrepresent the original compositions. In the course of this discussion it outlines ways in which authors appealed to audiences often stratified along class and gender lines. The chapter and article extend the concerns of the book, especially Chapter 6, with the discourse of popular songs of the early nineteenth-century song-and-supper rooms. Both continue to address questions of readership, both contemporary and more recent. 'The Cheek of the Young Person: Sexualized Popular Discourse as Subtext in Dickens' overturns assumptions about the canonical respectability of Dickens's earlier work. "'With Mike Hunt I Have Travelled Over the Town": the Norms of "Deviance" in Sub-respectable Nineteenth-century Song' uses popular but critically outlawed material to problematize the position of the literary critic and to offer an alternative to Raymond Williams' model of ideological development

Studies of inherited predisposition to cancer

Statement on how my publications have contributed to the advancement of knowledge and learning in the field EARLY RESEARCH The research studies undertaken for my MD thesis were concerned with the impact of genetic variation in the apolipoprotein B (Apo‐B) and Apo‐E genes on lipoprotein metabolism. I demonstrated that the catabolic rate of low density lipoprotein (LDL) is influenced by variation in the Apo‐B gene and this directly impacts on circulating levels of LDL; Notably that polymorphic variation in Apo‐B is a determinant of LDL levels in the general population and that germline mutation of the gene can result in a clinical phenotype analogous to familial hypercholesterolaemia. This period of research was followed by a Clinical Fellowship from the Imperial Cancer Research Fund during which I worked on the genetic epidemiology of breast, ovarian and colorectal cancer. Using large datasets I calculated age‐specific familial cancer risks for these cancers and using statistical modelling determined the most likely genetic models of inherited predisposition to breast, ovarian and colorectal cancer (CRC). Using these data a screening programme for the relatives of patients CRC based on their calculated lifetime risk was developed and implemented as part of the North East Thames Regional Clinical Genetics Service. It was demonstrated that family history of cancer could be used to identify those at risk of colonic cancer and to target appropriate screening. In the CRC family history clinic colonoscopic surveillance was shown to detect a high number of premalignant colonic polyps in those calculated to be at high genetic risk. An analogous programme for familial breast cancer was subsequently implemented for individulas with a family history of breast cancer. In this clinical setting use of familial history was shown to be an effective means of identifying women at risk of breast cancer who might benefit from early mammographic surveillance. The findings and experience demonstrated the clinical utility of dedicated family cancer clinics and established a framework for their operation within the United Kingdom. Collectively work undertaken during this period formed the basis of a PhD thesis. CURRENT RESEARCH INTERESTS AND ACHIEVEMENTS I am currently Professor of Molecular and Population Genetics, Division of Genetics and Epidemiology at the Institute of Cancer Research. The central theme of my research is to understand the biological basis of inherited susceptibility to cancer and specifically the identification and characterisation of genetic variation influencing cancer risk. Over the past 40 years the study of inherited susceptibility to cancer has proved to be a most informative area of cancer research – and it continues to be so. The results of this research, namely the identification of new susceptibility genes, provides for an understanding of the mechanisms of tumour biology, offering potential targets for novel therapeutic interventions. The ability to identify those at increased risk is of clinical relevance, in terms of primary and secondary interventions. Finally given the difficulties in unambiguously identifying causative exposures for some cancers, genetic associations are likely to be increasingly valuable via the Application for Degree of DSc – Richard S Houlston functional links they reveal that either endorse current aetiological hypotheses or suggest new ones that merit testing via gene‐environment specific hypotheses. IDENTIFICATION OF DISEASE GENES THROUGH POSITIONAL CLONING My first work in the area of identification of cancer genes was on Juvenile Polyposis (JPS), a rare classical Mendelian dominant condition conferring a high risk of CRC. We undertook a large family collection based on strict ascertainment criteria, which ultimately through international collaboration led to the identification of the disease gene, SMAD4, for JPS. Its identification has allowed families to be tested for JPS in the diagnostic and predictive settings in routine clinical practise. A similar emphasis on detailed family ascertainment allowed us to conduct a genome‐wide linkage scan of families segregating hereditary leiomyomatosis and renal cancer (HLRCC), and localise the gene for HLRCC to 1q42.3‐q43. Subsequently, as part of an international collaboration, through positional cloning we identified germline mutations in the gene encoding the Krebs cycle enzyme fumarate hydratase (FH) as the basis of HLRCC. While HLRCC is a rare disease the demonstration that mutation of FH can be a basis for tumour development provided contributing evidence of pseudo‐hypoxic drive in the development of cancer. Subsequent to these studies we were one of the first research groups to implement high‐density SNP arrays to conduct genome‐wide linkage scans. While the denseness of SNP marker maps means that there is increased power and improved localisation of disease genes the high density of SNP maps leads to the problem of linkage disequilibrium (LD) between markers inflating linkage statistics. To address this issue we developed the program SNPLINK to incorporate LD between markers into the likelihood calculations so that expected haplotype frequencies are correctly estimated. Prior to performing linkage scans of CRC and chronic lymphocytic leukaemia (CLL) families to search for novel disease loci we extensively piloted the utility of using high‐density SNP arrays. Firstly, we evaluated a pre‐release version of the Affymetrix 10K array successfully using this technology to localise and identify PTF1A as a cause of recessive cerebellar and pancreatic agenesis. Secondly, we validated the use of production Affymetric 10K arrays identifying disease genes for a number of Mendelian disorders including recessive paroxysmal nocturnal hemoglobinuria, vasculitis, merosin‐positive congenital muscular dystrophy, craniosynostosis and dominantly inherited renal dysplasia. Following on from these studies we analysed 206 CLL families identifying a disease locus at 2q21.2, thereby providing evidence for high‐moderate penetrance susceptibility to CLL. Through mutation screening we subsequently demonstrated that germline mutation of the gene CRCX4, which maps to 2q21.2 is implicated in a subset of familial CLL. To investigate Mendelian susceptibility to CRC we conducted a genome‐wide linkage screen of 104 CRC families in which germline mutations in the then known CRC predisposition genes had been excluded. The strongest evidence of linkage was provided by loci at 9p, 3p24, 13q31 and 17q24, albeit non‐significant at a genome‐wide threshold. These data indicate that if additional high‐moderate penetrance susceptibility genes exist for CRC, each accounts for only a small fraction of the familial risk. Application for Degree of DSc – Richard S Houlston IDENTIFICATION OF COMMON RISK VARIANTS FOR CANCER Over the last decade the opportunities for identifying high‐risk cancer genes through classical linkage and positional cloning strategies have dwindled. This has sparked renewed interested in the notion that much of the inherited predisposition to cancer is mediated through various combinations of common and rare‐disease causing genetic variants. Anticipating the requirement for large datasets of cancer cases to search for these classes of cancer susceptibility gene we developed the necessary infrastructure and protocols for large‐scale sample collection together with establishment of international consortia. These initiatives have allowed us to generate world‐class biobanks for multiple cancer types. Initially our search for common genetic variants affecting cancer risk was largely conducted adopting a candidate gene approach making use of analytical platforms technologies for parallel processing of genotyping. The spectrum of mutations in Mendelian disease genes, coupled with issues of statistical power, provided us with a rationale for pursuing association analyses targeting non‐synonymous SNPs (nsSNPs). To increase the likelihood of identifying predisposition variants we classified and catalogued the predicted functionality of all nsSNPs catalogued by dbSNP in genes relevant to the biology of cancer through cross referencing of KEG and other databases. In addition to studies of CRC, breast cancer, CLL our study of lung cancer provided evidence for a role for variants of the IGF and BAT3 in disease aetiology. Subsequent to studies focused on candidate genes using our infrastructure, we has been at the vanguard of implementing genome‐wide association studies (GWAS) to identify common, low‐penetrance loci for cancer without prior knowledge of location and function. We has successfully led GWAS studies of CRC, lung cancer, glioma, meningioma, CLL, acute lymphoblastic leukaemia (ALL), Hodgkin’s lymphoma (HL) and multiple myeloma (MM) being the first research group to identifying novel common disease variants for each malignancy. Importantly, prior to our studies no specific risk factors for ALL, CLL and MM had been identified. Collectively our work in this field of research has so far resulted in the identification of over 50 novel cancer loci constituting a large fraction (perhaps ~25%) of all common variants thus far identified by all researchers worldwide. In the design of GWAS we have shown in our studies of CRC and CLL the theoretical value of using cases enriched for genetic susceptibility by virtue of family history as a means of increasing study power to identify novel disease causing variants through association‐based analyses. As well as vindicating the hypothesis of low penetrance susceptibility to cancer our findings have provided insight into the biological basis of tumourigenesis, emphasising the role of genetic variation in developmental genes as determinants of cancer susceptibility for a number of malignancies. One of the anticipated deliverables from GWAS studies was that the identification of risk variants would provide fresh insights into cancer biology. Indeed few of the genes implicated by the GWAS scans have previously been evaluated in targeted association studies. Through the work of our group, insights into new pathways of tumourigenesis are emerging; for example, we have demonstrated that genetic variation in the B‐cell developmental genes, IKZF1, CEBPE, IRF4, IRF8, SP120, BAK1, and ARID5B, has been shown to determine the risk of B‐cell tumours. Application for Degree of DSc – Richard S Houlston Furthermore we have shown many of the risk variants have cis‐acting effects on gene expression rather than influencing risk through sequence variation in the expressed proteins. Similarly, several of the 20 CRC loci we have identified provide strong evidence for the involvement of components in the transforming growth factor‐β (TGFβ) superfamily signalling pathway in CRC development, most notably BMP2, BMP4, SMAD7 and GREM1. Intriguingly, we have demonstrated an association between chromosome Xp22.2 encompassing the developmental gene SHROOM2 and CRC risk. This represents the first evidence for a role of variation in the X‐chromosome variation in predisposition to a non–sex specific cancer characterised by different incidence rates in men and women. While the well established HLA association with HL represents a very strong genetic effect, the identification of risk variants at 2p16.1, 8q24.21 and 10q14 we have made has implicated important roles for networks involving MYC, GATA3 and the NFκB pathway in HL disease aetiology. Our findings in glioma have also highlighted the importance of variation in genes encoding components of the CDKN2A‐CDK4 signalling pathway in tumour development. Moreover, this pathway, elucidated through the extended interaction network of CDKN2A, incorporates TERT (through mutual interaction with HSP90) and other genes (including CCDC26) identified as risk factors. Gliomas a heterogeneous and following on from initial gene disocery experiments we have shown that the risk variants at 5p15.33 (TERT), 8q24.21 (CCDC26), and 20q13.33 (RTEL) have subtype‐specific effects consistent with different aetiological basis to the various glioma histologies. Similarly our work on the other major primary brain tumour, meningioma has implicated dysfunctional Wnt signalling as a biological basis for tumour development by virtue of variation in MLLT10. This together with our previous observation of a relationship between BRIP1 variation and meninigioma risk represent the only robust genetic associations for this tumour type reported thus far. Most recently the GWAS of MM we performed has identified three loci influencing MM risk. Our observation that genetic variation affecting CDCA7L and ULK4 genes affects MM risk has for the first time directly implicated genetically determined deregulation of MYC and mTOR‐mediated autophagy in the aetiology of the disease. Importantly our studies have provided the first direct and robust evidence for inherited genetic susceptibility to ALL, CLL, MM and lung cancer. This was especially profound for lung cancer a malignancy frequently cited as a solely attributable to environmental exposure. While it has long been postulated that individuals may differ in their genetic susceptibility to develop lung cancer in response to genotoxic insult prior to our studies evidence for such an assertion has been lacking. Through our GWAS of lung cancer we initially identified risk loci for lung cancer at 5p15.33 (TERT/CLPTM1), 6p21.33, and two at 15q25.1 (CHRNA5‐CHRNA3‐CHRNA4). These data thus provided the first evidence for common genetic susceptibility to lung cancer. We have subsequently shown through collaborative pooled analyses of other GWAS datasets that variation in RAD52C and CDKN2A are risk factors for squamous lung cancer and the 5p15.33(TERT) association is specific for risk of lung adenocarcinoma. Most SNP associations identified to date have been tumour specific, which is consistent with the epidemiological observations that most familial cancer risks are tumour specific. Evidence for Application for Degree of DSc – Richard S Houlston pleiotropic effects (reflecting generic effects or lineage‐specific effects) has been provided by our work showing that the 5p15.33 (TERT–CLPML1) locus influences the risk of many tumour types including glioma and lung cancer and the locus at 9p21.3 (CDKN2A–CDKN2B) influences the risk of both glioma and ALL risk in addition to melanoma. In contrast to high‐penetrance susceptibility, the effect of low‐penetrance variants on tumour phenotype may be limited or absent. Exploration of the relationship between SNP genotypes and tumour phenotypes is still in its infancy, but some associations are becoming apparent. One of the most striking genotype–phenotype relationships identified to date is the 10q21.2 (ARID5B) ALL association, which seems to be highly selective for the subset of B‐cell precursor ALL with hyperdiploidy directly implicating the developmental gene ARIDB5 in disease phenotype. Given the difficulties in unambiguously identifying causative exposures for many cancers, genetic associations have the potential to endorse current aetiological hypotheses or suggest new ones that merit testing through gene‐ and/or environment‐specific hypotheses. Demonstration of an effect on cancer risk that is mediated by an environmental exposure has been provided by the nicotinic acid receptor (CHRNA3–CHRNA5) locus that is associated with lung cancer through genetic variation influencing an individual’s propensity to smoke. Since the 15q24 association signal is a consequence of the D398N substitution in CHRNA5 which causes decreased response to nicotine agonists there is evidence for genetically‐determined nicotine dependency with biological plausibility. Our findings that variation in developmental genes is commonly the basis of GWAS signals for cancer generally favours such variation impacting early in tumourgenesis rather than impacting on late disease expression. Testing for association between risk variants and progenitor lesions theoretically offers the means of examining such an assertion. For most tumours this is unfortunately not possible. For CLL this is possible since we have shown that monoclonal CLL‐phenotype cells (monoclonal B‐cell lymphocytosis, MBL) detectable in ~3% of otherwise healthy persons and represent the progenitor lesion for CLL. Our observation that the risk variants for CLL influence affect the risk of MBL is consistent with the variants impact on early stage development of CLL rather than disease progression per se. Modelling all the single nucleotide polymorphisms (SNPs) in a GWAS simultaneously provides a means of deriving an unbiased estimate of the heritability explained by common variation. In concert with our gene discovery efforts using GWAS‐based strategies we have applied this form of statistical modelling to ALL and CLL GWAS datasets to derive estimates for heritability. Through these analyses we have shown that 59% of the total variation in CLL risk can be accounted for by common genetic variation, thereby providing the first direct data for a polygenic basis for susceptibility to CLL. Prior to our GWAS of ALL evidence although speculated was distinctly lacking and much of the contemporary thinking was that, given indirect evidence for the role of infection in disease aetiology any genetic susceptibility would be mediated through disordered HLA‐associated. Our analyses have quashed this hypothesis but have shown that 28% of the variance in childhood ALL risk can be ascribed to common variation. Application for Degree of DSc – Richard S Houlston Genetic and functional basis of GWAS signals To investigate if associations may have arisen owing to independent correlation of a tagSNP with more than one functional SNP, we searched for novel CRC susceptibility variants close to the BMP‐pathway genes GREM1, BMP4, and BMP2. We have shown that independent CRC predisposition SNPs close to BMP4 and BMP2. Near GREM1 we also found using fine‐mapping that the previously‐identified association between tagSNP rs4779584 and CRC was a consequence of two independent signals. As exemplified by MLH1‐93G>A polymorphism there is increasing evidence that high‐ and low‐penetrance variants can map to the same gene. Further support for such an assertion is supported by our observation of inactivating BMP4 mutations as a basis of familial CRC. Our work in this area has thus served to emphasise that genetic fine‐mapping studies can deconvolute associations, thus explaining some of the apparently missing heritability of common diseases. A long term outcome of GWAS is that knowledge gained about the underlying molecular basis of CRC may lead to the development of innovative therapeutic and preventative measures. Many of the risk loci identified thus far by GWAS map to non‐coding regions of the genome. For example, the 8q24.21 region is one of the most intriguing and important loci to emerge from GWASs. The genomic interval harbours independent loci with different tumour specificities including ones for CRC, CLL and HL. The region to which these cancer associations map is, however, bereft of genes or protein‐coding transcripts. Identification of the causal basis of association signals identified through GWAS is challenging and we has played a major role in elucidating the functional basis for the CRC associations, work that has underscored the role of inherited differential gene expression as a determinant of cancer susceptibility rather that mutation impacting on protein sequence which has typified Mendelian cancer susceptibility. Using a combinatorial approach of bioinformatics and molecular studies we have demonstrated the genomic region harbouring the 8q23 variant for CRC influences eukaryotic translation initiation factor 3, subunit H (EIF3H) expression and that up‐expression of EIF3H gene increases CRC growth and invasiveness thus providing a biological mechanism for the 8q23.3 association. Similarly our work has demonstrated cis‐acting regulation of the TGF‐beta signalling gene SMAD7 as a basis for the 18q24 association and cis‐acting regulation of BMP4 provides a basis for the 14q22.2 association. At 8q24.21 we showed rs6983267 was maximally associated with CRC risk. A collaboration with Lauri Aaltonen (Helsinki University) led to the demonstration that rs6983267 annotates an enhancer element affecting the binding of Wnt‐regulated transcription factor TCF4. This coupled with the finding that rs6983267 directly interacts with the MYC promoter has provided a biological basis for the 8q24 association. Application for Degree of DSc – Richard S Houlston GENETIC EPIDEMIOLOGICAL ANALYSES Studies of CLL Although familial clustering of CLL had long been recognised direct evidence for inherited genetic susceptibility has been lacking. We have made a significant contribution to establishing that inherited genetic factors play a role in the development of CLL. Even prior to our linkage and association studies through the ascertainment of striking families segregating CLL we provided overwhelming case for the existence of genetic predisposition. Furthermore, our observations on the repertoire and frequency of IGVH usage in familial and sporadic CLL favour a genetic basis to CLL development rather than a simple environmental aetiology. Coupled with such studies our studies of MBL have provided insight in disease development. Risk prediction and statistical modelling of familial risk The distribution and genotypic risk conferred by disease alleles is crucial for determining the applicability to relative or absolute risk circumstances. Diagnostic testing for highly penetrant mutations is now part of standard clinical care for cancer families in

Building bridges? An evaluation of the costs and effectiveness of the separated parents information programme (PIP)

The Separated Parent Information Programme (PIP) is the first nationally available parent education programme for parents involved in litigation over contact and residence in England. The programme is a Contact Activity, introduced by the Children and Adoption Act 2006 as an additional tool for courts to facilitate contact. PIP is a four hour group programme for parents referred by the court. Both parties, i.e. the applicant and respondent, are required to attend the programme, but former couples attend separate groups. The groups are designed to include both men and women. The aim of the programme is to encourage parents to focus on children’s needs and perspectives. The programme is delivered by trained providers from mediation, counselling or contact services backgrounds

Meta-Analysis of Genome-Wide Linkage Studies in Celiac Disease.

OBJECTIVE: A meta-analysis of genome-wide linkage studies allows us to summarize the extensive information available from family-based studies, as the field moves into genome-wide association studies. METHODS: Here we apply the genome scan meta-analysis (GSMA) method, a rank-based, model-free approach, to combine results across eight independent genome-wide linkages performed on celiac disease (CD), including 554 families with over 1,500 affected individuals. We also investigate the agreement between signals we identified from this meta-analysis of linkage studies and those identified from genome-wide association analysis using a hypergeometric distribution. RESULTS: Not surprisingly, the most significant result was obtained in the HLA region. Outside the HLA region, suggestive evidence for linkage was obtained at the telomeric region of chromosome 10 (10q26.12-qter; p = 0.00366), and on chromosome 8 (8q22.2-q24.21; p = 0.00491). Testing signals of association and linkage within bins showed no significant evidence for co-localization of results. CONCLUSION: This meta-analysis allowed us to pool the results from available genome-wide linkage studies and to identify novel regions potentially harboring predisposing genetic variation contributing to CD. This study also shows that linkage and association studies may identify different types of disease-predisposing variants

Identification of low penetrance alleles for lung cancer: the GEnetic Lung CAncer Predisposition Study (GELCAPS).

BACKGROUND: Part of the inherited risk to lung cancer is likely to include common, low risk alleles. The identification of this class of susceptibility is contingent on association-based analyses. We established GEnetic Lung CAncer Predisposition Study (GELCAPS) to collect DNA and clinico-pathological data from a large series of cases and a series of spouse/partner controls, thereby generating a key resource for the identification of low risk alleles. METHODS: GELCAPS was one of the first genetic epidemiological trials in the UK to be adopted by the National Cancer Research Network (NCRN) onto its portfolio with the participation of over 100 oncology departments specialising in the management of lung cancer. RESULTS: Samples from over 5,000 independent lung cancer cases and 2,000 controls have so far been assembled through GELCAPS. CONCLUSION: GELCAPS represents one of the largest datasets of its type in the world capable of informing on the contribution of low penetrance alleles to the development of lung cancer and the influence of genetic variation on outcome. In addition our experience in developing the GELCAPS serves to illustrate how large DNA biobanks for genetic analyses can be rapidly generated within the UK using the NCRN.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Modal Control of Vibration in Rotating Machines and Other Generally Damped Systems

Second order matrix equations arise in the description of real dynamical systems. Traditional modal control approaches utilise the eigenvectors of the undamped system to diagonalise the system matrices. A regrettable consequence of this approach is the discarding of residual off-diagonal terms in the modal damping matrix. This has particular importance for systems containing skew-symmetry in the damping matrix which is entirely discarded in the modal damping matrix. In this paper a method to utilise modal control using the decoupled second order matrix equations involving non-classical damping is proposed. An example of modal control successfully applied to a rotating system is presented in which the system damping matrix contains skew-symmetric components

Emotional adaptation to relationship dissolution in parents and non-parents: A new conceptual model and measure

Relationship dissolution can cause declines in emotional well-being, particularly if there are children involved. Individuals’ capacity to cope with the pragmatics of the situation, such as agreeing childcare arrangements, can be impaired. Before now, there has been no psychometric test to evaluate individuals’ emotional readiness to cope with these demands. This paper presents a model of emotional adaptation in the context of relationship dissolution and its key assumptions, and validates the Emotional Adaptation to Relationship Dissolution Assessment (EARDA). In Study 1 (Sample 1, n = 573 separated parents, Sample 2, n = 199 mix of parents and non-parents), factor analyses support the EARDA as a unidimensional scale with good reliability. In Study 2 (using Sample 1, and Sample 3, n = 156 separated parents) the convergent, discriminant, concurrent criterion-related, and incremental validity of the EARDA were supported by tests of association with stress, distress, attachment style, and co-parenting communication and conflict. In Study 3, the nomological network of emotional adaptation to relationship dissolution was explored in Sample 2 using cluster analysis and multi-dimensional scaling (MDS). Emotional adaptation clustered with positive traits and an outward focus, and was negatively associated with negative traits and an inward focus. Emotional adaptation was conceptually located in close proximity to active and adaptive coping, and furthest away from maladaptive coping. In Study 4 (n = 30 separated parents embarking on mediation), high, medium, and low emotional adaptation to relationship dissolution categories correlated highly with mediators’ professional judgement, offering triangulated face validity. Finally, in Study 5, EARDA scores were found to mediate between separation characteristics (time since break up, whether it was a shock, and who initiated the break up) and co-parenting conflict in Sample 1, supporting the proposed model. The theoretical innovation of this work is the introduction of a new construct that bridges the gap between relationship dissolution and co-parenting. Practical implications include the use of the measure proposed to triage levels of support in a family law setting
