Fetal and postnatal patterns of growth in a bi-ethnic sample of children

Norris, Thomas January 2015 (has links)
Background: Substantial variation exists between ethnicities in both birth weight and the prevalence of obesity-related non-communicable diseases (OR-NCDs). South Asians, who display a reduced birth weight and increased risk of developing these OR-NCDS, have been the focus of much of the research into the developmental origins of health and disease (DOHaD) paradigm. However, little research utilising ultrasonically derived estimates of fetal growth has been conducted. The use of more direct measures of fetal growth may also enable the identification of relationships between patterns of fetal growth with patterns of postnatal growth, explicitly, whether periods of restricted or rapid growth lead to postnatal catch-up or down, respectively. The known differences in birth weight existing between South Asians and White British infants may also have implications for the assessment of neonatal health in these sub-groups when using a population derived birth weight chart, such as the UK-World Health Organisation (UK-WHO). Customised charts, which adjust for maternal variables including ethnicity, have been recommended for clinical practice, yet evidence for their efficacy is varied. Objectives: The aims of this thesis were to: 1) investigate whether fetal growth patterns differ between Pakistani and White British foetuses and determine whether maternal size and demographic variables mediate any such differences; 2) produce a birth weight chart adjusting for ethnicity and compare this to the UK-WHO and customised birth weight charts to determine which chart better identifies neonates at risk of the adverse delivery and neonatal outcomes associated with small-for-gestational-age (SGA) and large-for-gestational age (LGA); 3) identify whether there is evidence of weight growth tracking between fetal and infant periods and determine whether patterns of fetal growth predict patterns of postnatal growth. Methods: All data come from the Born in Bradford (BiB) birth cohort. Objective 1: Multilevel models and fractional polynomials were employed for the modelling of fetal weight, head circumference (HC) and abdominal circumference (AC) growth. Potential mediators of the effect of being of Pakistani origin were entered into the model and the effect on the ethnicity variable was assessed. Objective 2: Ethnic specific birth weight charts (BiB) were constructed using the LMS method. SGA and LGA were defined as a birth weight <10th and >90th relative to the BiB, the UK-WHO or the customised charts. Sensitivity, specificity, positive & negative predictive values and area-under-the curve were calculated for each of the three charts SGA and LGA cut-offs, to assess the predictive ability of each chart for a range of delivery and neonatal outcomes. Objective 3: Multilevel models were employed for the modelling of fetal and postnatal growth. Fitted values were produced at 20, 30, 40 prenatal weeks & 1, 3, 6, 9, 12, 24 postnatal months in both an internal reference and the sample population. Z scores were calculated and conditional Z scores were generated to account for regression to the mean. Growth tracking was defined as change in Z score ≤ 0.67 & ≥ -0.67. Restricted and rapid fetal growth were defined as a change in Z score in the fetal period of <-0.67 and >0.67, respectively. Catch-down and catch-up growth were defined in the same way, except in the postnatal period. ANOVAs were used to test for differences in size and growth by type of fetal growth. Furthermore, logistic regression and a sensitivity and specificity analysis were employed to examine the predictive ability of the type of fetal growth. Results: Objective 1: Pakistani fetuses were significantly smaller and lighter than White British fetuses, throughout gestation. In terms of weight, Pakistani fetuses were approximately 2.25% lighter at 20 weeks, 4.13% at 30 weeks and 5.94% at 40 weeks. The differences in size for AC and HC between the two groups were not as great, with the AC and HC of Pakistani fetuses being approximately 4.1% and 1.25% smaller, respectively, at 40 weeks. Despite these significant differences in size the pattern of growth for HC and weight was not significantly different between the two groups. There was a trend for Pakistani fetuses to display a greater deceleration of growth in the final trimester (figure 4-12). The biggest mediators of the effect of being of Pakistani origin were maternal height and weight. Objective 2: Classifying infants as SGA or LGA by the BiB, UK-WHO or customised charts had low predictive utility for the outcomes under investigation. Despite the fact that the BiB ethnic specific birth weight reference provided significantly better prediction for more outcomes than both the UK-WHO and customised charts in both White British and Pakistani infants, with the exception of shoulder dystocia, AUROC values for all three charts were all below 0.61. Objective 3: The prevalence of tracking within the same centile band from 20 weeks gestation to 2 years was 10.82%. Infants who experienced restricted fetal growth remained significantly lighter than those who had not, for the duration of infancy. In this group however, there was a pattern of greater growth than expected during infancy. This was opposite to the pattern observed in infants who had experienced rapid fetal growth, who exhibited less growth than expected during infancy. However, the ability of the type of fetal growth to predict the pattern of postnatal growth was minimal, with only rapid fetal growth being significantly associated with increased odds of catch-down growth in infancy. Conclusions: No ethnic difference in the pattern of growth was found in terms of the whole body (weight) or in HC. The trend for reduced growth of the AC in Pakistanis may be a result of a reduced growth of the visceral organs during the third trimester, which may lead to both an altered liver metabolism and impaired renal function in post-natal life. Although being small or large at birth may increase the risk of an adverse neonatal outcome, size alone is not sensitive or specific enough with current detection to be a useful clinical tool. The finding that neither restricted nor rapid fetal growth predicted postnatal catch-up growth may suggest that the timing of canalisation is outside of the fetal period. If infant catch-up and down growth are not associated with periods of restricted or rapid fetal growth, the definitions of these growth patterns may need revising.

Ideal Performance Practice for Silent Film: An Overview of How-to Manuals and Cue Sheet Music Accompaniment from the 1910s – 1920s

Anderson, Shana C. 26 November 2013 (has links)
This thesis argues that how-to manuals and cue sheets are indicative of ideal performance practice amongst musicians from the silent film era. Pre-scored music was widely practiced amongst musicians. How-to manuals and cue sheets helped the musician accurately and consistently accompany a film. Authors of period manuals include W. Tyacke George, Edith Lang and George West, Ernst Luz and George Tootell. Compilers of cue sheet include James C. Bradford, Ernst Luz, Edward Kilenyi and Michael P. Krueger. Cue by cue analyses of The Cat and the Canary and The Gaucho show a high repetition of music, establishing continuity between the music played and the image on the screen. This shows how compilers associated music and film. These manuals and cue sheets prove that the musician community strove for a close connection between the image on screen and accompaniment. By 1920, arbitrary improvisation was unacceptable.

Saturday Night and Sunday Morning: The Story of the Bradford Riots.

Bujra, Janet M., Pearce, Jenny 2014 April 1930 (has links)
Saturday Night and Sunday Morning marks the tenth anniversary of the Bradford riot of Saturday 7 to Sunday 8 July 2001. The day began with a peaceful demonstration against a banned Far Right march but ended in one of the most violent examples of unrest in Britain for 20 years. More than 320 police officers were injured as they battled rioters who hurled missiles and petrol bombs, pushed burning cars towards them and torched buildings. Criminal acts of looting characterised the final hours. Riot damages amounted to GBP7.5 million. In the aftermath, nearly 300 arrests took place and nearly 200 were charged with riot leading to prison sentences of four years or more. Images of the riot, and of a smaller disturbance which followed on one of its traditionally 'white' estates, have haunted Bradford ever since. Nine years later, in August 2010, Bradford faced another Far Right provocation. The English Defence League came in force to demonstrate against Bradford's Muslim population. Bradford braced itself. However this time, Asian lads mostly stayed off the streets and the police worked with the council, communities and local activists to keep order against the threat of violence. Saturday Night and Sunday Morning traces Bradford's journey over the decade, beginning with the voices of rioters, police and others interviewed after the 2001 riot and ending with those of former rioters, citizens, police and politicians following the EDL protest. The authors argue that while 2001 reflected a collective failure of Bradford District to address a social legacy of industrial decline in a multicultural context, 2010 revealed how leadership from above combined with leadership from below restored its confidence and opened up possibilities for a new era in Bradford's history and prospects. Saturday Night and Sunday Morning is written by two authors from the University's renowned Department of Peace Studies who balance research with an active commitment to peace, economic regeneration and social justice in Bradford.

Interpretive ground and moral perspective : economics, literary theory, early modern texts

LiBrizzi, Marcus. January 1996 (has links)
This dissertation provides a critical, systematic survey of economics in literary theory and practice. Since Aristotle, economic categories have been used as interpretive grounds on which to conceptualize the literary text and distinguish it as a moral or normative sphere. Because economic categories presuppose different norms of individual and social action, the use of a specific category as an interpretive ground generates a particular outlook or moral perspective. / In the first part of the discussion, we critique theories in which the literary text is conceptualized as an economy. After distinguishing three distinct models of the "textual economy," we evaluate them in terms of their logical consistency and normative presuppositions. Selecting the model that is the most logically consistent and normatively valuable, we study two early modern works to see if this model operates as an intentional device implicated in a work's form and content. The works chosen are William Shakespeare's Sonnets and William Bradford's history "Of Plimoth Plantation," both of which display a facination with economic discourse. / The second part of the discussion takes up the question of economics in the theory and practice of putting texts in context. We distinguish four different models of contextualization that depend on economic categories. Explicitly or implicitly, contemporary research agendas and critical positions depend on these categories to situate a literary text in a specific setting. An economic category like exchange, for example, is frequently privileged as a common ground, a shared quality or characteristic used to integrate a text with a context. After critiquing models of contextualization, we synthesize the best they have to offer into a new framework. We then use this framework to situate the texts by Shakespeare and Bradford into the historical settings of their production and reception. The result is a picture of the text in context that is vital, a moving picture, quite unlike the customary still life of artifact and background.

Nurturing writing skills in the primary literacy lessons of the 'City of Film' : the impact of using moving images on attainment and motivation

Florack, Franziska January 2016 (has links)
Despite a constant rise in the attainment of Sats results year on year, the perception remains that British primary school children are underachieving and that they are reluctant readers and writers. In order to motivate their students, some teachers use films as a visual stimulus to provide students with ideas and create a personal and emotion connection with the written text. In the school years of 2013/14 I followed 21 primary classes which were taking part in a ‘film literacy’ scheme run by Bradford UNESCO City of Film. This initiative saw the training of teachers in the use of film as a tool in literacy lesson with the hope to raise attainment and motivation. Students and teachers completed questionnaires and interviews which were analysed in conjunction with observations and the students’ literacy grades. The research showed that both students and teachers recorded an increase in motivation. Further, significant progress in attainment also became evident: film literacy students raised their grades by 23.3% beyond the expected year-on-year increase. Improvements in inference, comprehension and vocabulary were especially praised. Students from schools with a low-income environment benefitted in particular. The research discusses six potential reasons for these changes, two of which are based on the belief that film is a particularly suitable medium for teaching as it engages students emotionally. Although the thesis acknowledges that Bradford involved a unique group of schools in the film literacy training and research, it nevertheless argues that film could be useful addition to primary classrooms due to its potential ability to raise standards and engage reluctant young writers.

Beyond Bradford's Journal: The Scrooby Puritans in Context

January 2015 (has links)
abstract: This dissertation explores the claims, put forth by William Bradford in his journal Of Plimoth Plantation, that persecution was the primary motivation for removal from England to Holland by the Scrooby Puritans in 1608, and challenges the historiographical acceptance of those claims. The dissertation examines monarchical, ecclesiastical and historical records from 1590-1620 to determine if there was any evidence to support Bradford’s claims of persecution. Finding scant evidence of physical persecution at the hands of royal, civil, or ecclesiastical authorities, the dissertation turns to the socioeconomic factors which may have contributed to the Scrooby Puritans decision to leave England and take up residence in Holland for twelve years. Finding no significant socioeconomic push factors, attention is then turned to the theological underpinnings of the group to determine if theology may have driven their persecution narrative. It concludes that the Scrooby Puritans may not have been fleeing from authorities trying to confine them for their religious beliefs, but from the corruption of their very souls, had they remained in England and under the theological influences of the Church of England. / Dissertation/Thesis / Doctoral Dissertation History 2015

Systematic Exploration of Associations Between Select Neural and Dermal Diseases in a Large Healthcare Database

Kirbiyik, Uzay 03 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / In the age of big data, better use of large, real-world datasets is needed, especially ultra-large databases that leverage health information exchange (HIE) systems to gather data from multiple sources. Promising as this process is, there have been challenges analyzing big data in healthcare due to big data attributes, mainly regarding volume, variety, and velocity. Thus, these health data require not only computational approaches but also context-based controls.In this research, we systematically examined associations among select neural and dermal conditions in an ultra-large healthcare database derived from an HIE, in which computational approaches with epidemiological measures were used. After a systematic cleaning, a binary logistic model-based methodology was used to search for associations, controlling for race and gender. Age groups were chosen using an algorithm to find the highest incidence rates for each condition pair. A binomial test was conducted to check for significant temporal direction among conditions to infer cause and effect. Gene-disease association data were used to evaluate the association among the conditions and assess the shared genetic background. The results were adjusted for multiple testing, and network graphs of significant associations were created. Findings among methodologies were compared to each other and with prior studies in the literature. In the results, seemingly distant neural and dermal conditions had an extensive number of associations. Controlling for race and gender tightened these associations, especially for racial factors affecting dermal conditions, like melanoma, and gender differences on conditions like migraine. Temporal and gene associations helped explain some of the results, but not all. Network visualizations summarized results, highlighting central conditions and stronger associations. Healthcare data are confounded by many factors that hide associations of interest. Triangulating associations with separate analyses helped with the interpretation of results. There are still numerous confounders in these data that bias associations. Aside from what is known, our approach with limited variables may inform hypothesis generation. Using additional variables with controlled-computational methods that require minimal external input may provide results that can guide healthcare, health policy, and further research.
