The objective of this thesis is to develop statistical models for multivariate road accident data. Two directions of research are followed: graphical modelling for contingency tables cross-classified by accident characteristics, and hierarchical Bayesian models for multiple accident frequencies of different types modelled jointly. Multi-dimensional tables are analysed and it is shown how to use collapsibility to reduce the dimensionality of the analysis without the problems of Simpson's paradox. It is revealed that accident severity and the number of casualties are associated, and that these variables are mainly influenced by the number of vehicles and speed limit. Graphical chain models allow causal hypotheses to be formulated and it is shown how they are valuable tools for empirical research about road accident characteristics. The hierarchical Bayesian models developed combine generalized linear models with random effects. The novelty of these models consists in the joint modelling of multiple response variables. The models account for overdispersion and they are used for accident prediction and for ranking hazardous sites. All models are fully Bayesian and are fitted using Markov Chain Monte Carlo methods. It is shown that multiple response variables models are superior to separate univariate response models. Some theoretical problems are examined regarding the maximum likelihood estimation process for the two parameters negative binomial distribution. A condition is given that is equivalent with unique maximum likelihood estimators. The two directions of research are connected by using graphs to describe the models. In addition, a new Bayesian model selection procedure for contingency tables is proposed. This is based on Gibbs sampling and avoids problems associated with asymptotic tests. The conclusions revealed here can help practitioners to design better safety policies and to spend money more wisely on sites that really are dangerous.

A revised lithostratigraphy and glacial history of north Hertfordshire and south Bedfordshire is based upon detailed textural data in the clay to fine gravel fraction, carbonate content, small clast lithological data and macrofabrics, derived from laboratory and field analyses of tills from 30 sites. These include four deep boreholes sunk within the Hitchin Gap. A range of statistical procedures was used, including multivariate analysis of the petrographic properties, enabling the identification of tills from two separate incursions into the Gap. A further till-type was identified in south Bedfordshire indicating an ice advance from the northwest/NNW extending at least as far east as Milton Bryan. Statistical comparison with tills in the neighbouring Vale of St. Albans suggested the presence of the Ware Member till within the Gap. Two hypotheses are suggested to explain variations in lithological content of tills north of the Chalk scarp. The first envisages ice entering the study area along the different trajectories suggested by Fish and Whiteman (2001). During the early part of the glaciation, ice reaching the west of the study area would approach from the north, crossing a shorter distance over Chalk bedrock and collecting less chalk and flint than ice moving into the eastern part of the study area. The second hypothesis invokes an incursion of ice from a northwest - NNW direction into the west of the study area, depositing a chalk-free till. This is subsequently assimilated by ice from the northeast, resulting in the final deposition of a homogeneous mixture of debris from the two advances, with a lower chalk content than tills found to the east. The outcome of either of these scenarios is a till with a low acid-soluble content and low flint/quartz ratio in the west of the study area, as found during this work. Within the Hitchin Gap, a lobe of ice, probably an early part of the northeasterly advance, deposited a lower till. This is considered to be earlier than the Ware Member till and has more variable lithological characteristics and a finer matrix that the higher tills. The latter are mainly melt-out, flow or slumped tills with occasional instances of lodgement and deformation. They represent in situ wasting of dead ice within the Gap. Surface tills in the Gap form a continuum with tills to the north and comprise mainly deformation tills, deposited by the final northeasterly re-advance of ice responsible for widespread coverage of the region, with the exception of the Chiltern Hills southwest of Hitchin. No evidence is found of more than one lithostratigraphic unit of till outside the Hitchin Gap.

This thesis examines some social policies and public health measures in the small county of Bedford, within the national context, 1904-38. No other such study exists which covers these aspects; it will, therefore, fill a gap in the body of knowledge. At this time, national and imperial needs for a healthy British race were paramount in the minds of politicians and social reformers, particularly in the face of competition for industrial and military supremacy from other powers, including Germany and the United States of America. Certain key themes permeated this era: the changing functions of local and central government, the role of the state and voluntary sectors, and a medical profession divided between those employed in preventive medicine, and those in private practice. However, war, the preparation for war and its after effects have been found to be the most significant factors. George Newman (1870-1948), figures large, because he played a major part in public health initiatives, firstly, as part-time County Medical Officer of Health to Bedfordshire County Council (1900-07), and then at central government level, as Chief Medical Officer of the Board of Education (1907-35), and of the Ministry of Health (1919-35). Two methodological tools were used in this thesis. Historical research was carried out using, mainly, primary source material, and an empirical study was undertaken using a descriptive case study approach. These methods enabled the collection of quantitative and qualitative data and helped to determine both the final content, and the form in which the research was presented. Chapter 1, the Introduction, provides a background to the key figures and themes discussed and describes the intra-county differences in Bedfordshire. Chapter 2 concerns infant mortality, as it is an indicator of the health ofthe whole community. Chapter 3 describes the health of school children, because the Government was particularly anxious about their condition, as they would be needed for industrial and imperial expansion, and in the event of war. Chapter 4 concerns the welfare of children. It provides examples of how the state and voluntary sectors strove to preserve child life, despite problems such as orphanhood and cruelty, and yet still attempted to meet the needs of the British Empire for labour. Chapter 5 discusses women's health, as it was relatively neglected by central government in this period. It takes the form of a case study and makes use of oral testimony from a cohort of 84 women who lived in Bedfordshire in the inter-war years. Chapter 6, the conclusion, examines the effect of war, the role played by the voluntary and state sectors, and the divided medical profession. It also considers the extent to which Bedfordshire led, or lagged behind national social policies and public health measures, and the progress made towards a healthier nation until 1938, the last full year of peace in Europe before the outbreak of World War II.

This research presents a demographic investigation into the effects the development of Britain’s railways in the Victorian Era had on the largely rural counties of Hertfordshire, Bedfordshire and Buckinghamshire. A ‘gateway’ to London, this region was traversed by many lines with a wide range of impacts. Railway historiography has questioned the extent to which railways affected national development; contemporary views of their central importance giving way to more critical opinion. Local rural studies have been recognised in addressing this; these at present are, however, few. Comparing and contrasting the three counties, the findings were used to create hypotheses of rural impacts, subsequently tested for accuracy and applicability by comparison with individual settlements. They demonstrated that occupations became decreasingly agricultural; railways having varying involvement. Sometimes a key factor, mostly they were of a supporting nature triggering knock-on effects. Land use became more urbanised but this was not railway originating; contrarily land use affected rail development itself. Railways, nonetheless, actively boosted urbanisation and industry by 1900, and in cases even supported agriculture. Population changes were assisted by railways, particularly rural-urban migration, but while aiding later in the period, railways did not initiate the process. A case study of Wolverton (Buckinghamshire), the first planned ‘railway town’, reveal exceptional differences even down to the appropriateness of the broader historiography. Limited prior research on this settlement type had been undertaken, and this study revealed their development was more complex than at first glance. As a result, a new structural framework was created to explain how they could transform from company tool to independent town. The contribution of this research is thus threefold. In analysing a new region, another area is added to a growing number collectively building a national understanding from a local level. As a rural region yet close to London, this shows that while current historiographical ‘facilitator’ views are correct, variation was rife. The hypotheses present a starting point for future rural rail studies – a method for comparing regions alongside a list of investigable aspects. Lastly, the proposed model for ‘railway town’ development provides a framework for comparison not just of these settlements but potentially other forms of planned ‘company town’. While railways were one factor among many, their importance should not be underestimated.

This study of Norfolk and Bedfordshire in the civil war and Interregnum was based on an analysis of the membership of the various committees appointed for the counties between December 1642 and March 1660. The members of the committees were divided into groups for analysis according to the dates of their first and last appointments. The gentry of Norfolk and Bedfordshire, which were both Parliamentarian counties, filled the committees of the 1640s, as they had the commissions of the peace in the 1630s. After the execution of the King in January'' 1649, the membership of the Bedfordshire committees was drastically changed by the loss of almost all the gentry members, while the Norfolk committees remained largely unchanged until I65I-I652. The difference between the counties was traced to the displacement of the secluded MPs- from the committees; the probably voluntary withdrawal of the Bedfordshire gentry; the weaker and more fluid gentry community and the greater penetration of radical political and religious ideas in Bedfordshire. Throughout the 1650s, Bedfordshire was administered by people new to county office, of lower social rank and more radical opinions than their gentry predecessors• Similar new people became important in Norfolk after I65I, but they did not replace the gentry, who retained their role and influence. In late 1659 and early 1660, the gentry in both counties returned to sole control of local government, displacing the new officials of the 1650s. A similar pattern in the type of committeemen was observed in both counties: the committeemen appointed before 1649 and in 1660 were of the same social rank as those holding county office before 1640, but the committeemen appointed for the first time I649-I656 were of markedly lower social origins. It was noted that in Bedfordshire, and to a much lesser extent in Norfolk, these new officials of the 1650s proved a viable alternative administration to the traditional gentry elite. / Arts, Faculty of / History, Department of / Graduate

Policing in The United Kingdom is an intricate business, balancing the enforcement of statute and other laws while dealing with public safety and security. Policing engages a diverse and complicated set of organisational structures and processes relying heavily on the skill and expertise of officers on the ground. Their role in preventing and or intercepting crime before, during and after it occurs is integral to sustaining peace, security, law and order in communities. The police operational and logistics staff work day to day with information and communication technologies, ranging from conventional databases and information systems to ubiquitous and specialised tools.  Understanding the use of technology and its management in policing has formed the backbone of this research conducted through a qualitative approach. This study adopted an interpretive paradigmic analytical lens using ethnography situated in the workplace as a methodology. The qualitative study took the form of field immersion for nine months using interviewing, and shadowing/observation to suit the complexity of the socio-technical context. Analysis was conducted using thematic analytical methods. Understanding how the police force interact with and shape the way that information and communication technologies enable them to fight crime is, then, the subject of this thesis. The findings highlighted the complexities and  intricacies involved in the use of technology, identifying unique differentiations in the way technology is engaged and integrated into policing including comparative understanding relative to other sectors and industries.  On the whole the central features of this work highlight understanding of the role information and communication technologies; usefulness, usage in practice and operational activity, strategic business goals, knowledge management, business intelligence and intelligence led architecture, governance and performance models in policing the county of Bedfordshire, England.
