Ecologically, the hyporheic zone (HZ) performs numerous roles within stream ecosystems (e.g. habitat, refugia from floods and droughts, nutrient cycling, pollution attenuation) with the dominant control on these various roles sediment composition. Recently, the body of literature on the role of sediment in the HZ has grown, though these studies rarely extend beyond the reach scale with little regional scale research undertaken in England and Wales. In this thesis, meio- and macrofaunal hyporheic assemblages at two depths (20cm and 50cm) across four geological regions (chalk – fine sediment, sandstone - fine to medium sediment and limestone – coarse sediment) two seasons (summer (n = 396) and winter (n = 192)) are described. The influence of recent glaciations (Devensian) on the distribution of stygobite fauna (summer (n = 192) and winter (n = 98)) is also considered. A reach scale experimental manipulation of sediment composition in the HZ of a highly dynamic, species rich and diverse study site (limestone) was also undertaken. I found the influence of glaciation on stygobite fauna still apparent in the two limestone areas with macrofaunal sized stygobite species rare or absent in both limestone areas. Meiofaunal sized stygobite fauna Antrobathynella stammeri (Crustacea: Syncarida) were recorded from the glaciated limestone site. These results suggest large stygobite fauna are rare or absent in the limestone areas of Northern England with meiofaunal stygobites possibly surviving in sub-glacial refugia. Stygobite fauna were abundant in southern England with alternative migratory routes north discussed (e.g. River Severn catchment and chalk aquifers). Geological regions had characteristic fauna with species richness and abundance of meio- and macrofauna high in the HZ of both limestone areas. Conversely, species richness and abundance was low in the chalk and sandstone HZ. The chalk HZ had a high abundance of macrofaunal sized Crustacea (Gammarus pulex) and low abundance of meiofaunal sized Crustacea (Copepoda). This suggested mechanical properties (burrowing) rather than morphology (body size and shape) was important in fine sediments, whereas in the limestone HZ morphology rather than mechanical properties was important. In the experimental study results were more intuitive with meiofauna abundant across all sediment treatments (fine, mixed, coarse and natural) with macrofauna abundant in sediment treatments containing a high proportion of coarse material. These results suggest Copepoda assume a greater role in ecological processes in fine sediment patches within a dynamic HZ, whereas when fine sediment dominates a system (e.g. chalk HZ) then the role of Copepoda is reduced. One implication could be the use of Copepoda as indicators of colmation and hydrologic exchange in the assessment of ecosystem health and give an indication of the refugial capacity of the HZ from projected high and low flow events in light of UK climate change forecasts.

No / Discussion of the declared policies of the Catholic Church in England and Wales, since 2001, with regard to the ongoing status of priests convicted in criminal courts of offences against children is presented. The extent to which these policies have followed recommendations 77 and 78 of A Programme for Action (Nolan, 2001a) and the extent to which they have resulted in the laicisation (removal from the clerical state) of priests are both explored, using national data and with reference to two particular cases from the Diocese of Salford. The potentially adverse impact on victims and survivors of any mismatch between the rhetoric of policy and the reality of practice by the Church is emphasised. Data presented demonstrate that, between November 2001 and September 2010, a majority (64%) of relevantly convicted and sentenced priests had not been laicised as would be expected. Suggestion is made that the Church is inhibited in carrying out its declared policies because it is attempting to serve legitimacy communities beyond victims and survivors of clerical abuse. Full commitment to the paramountcy principle by the Church and genuinely independent external scrutiny of its relevant decision-making processes are recommended.

Medieval castle slighting is the phenomenon in which a high-status fortification is demolished in a time of conflict. At its heart are issues about symbolism, the role of castles in medieval society, and the politics of power. Although examples can be found throughout the Middle Ages (1066–1500) in England, Wales and Scotland there has been no systematic study of the archaeology of castle slighting. Understanding castle slighting enhances our view of medieval society and how it responded to power struggles. This study interrogates the archaeological record to establish the nature of castle slighting: establishing how prevalent it was chronologically and geographically; which parts of castles were most likely to be slighted and why this is significant; the effects on the immediate landscape; and the wider role of destruction in medieval society. The contribution of archaeology is especially important as contemporary records give little information about this phenomenon. Using information recovered from excavation and survey allows this thesis to challenge existing narratives about slighting, especially with reference to the civil war between Stephen and Matilda (1139–1154) and the view that slighting was primarily to prevent an enemy from using a fortification. The thesis proposes a new framework for understanding how slighting is represented in the archaeological record and how it might be recognised in the future. Using this methodology, a total of 60 sites were identified. Slighting often coincides with periods of civil war, illustrating the importance of slighting as a tool of social control and the re-assertion of authority in the face of rebellion. Slighting did not necessarily encompass an entire site some parts of the castle – halls and chapels – were typically deliberately excluded from the destruction. There are also examples which fit the old narrative that slighting was used to prevent a fortification falling into enemy hands, but these cases are in the minority and are typically restricted to Scotland during the Scottish Wars of Independence. Given the castle’s role in shaping the landscape – acting as a focus for seigneurial power and precipitating the creation and growth of towns – it is important to understand how slighting effected nearby associated settlements. The evidence suggests that larger towns were able to prosper despite the disruption of slighting while smaller settlements were more likely to decline into obscurity. Importantly towns themselves were very rarely included in the destruction of slighting.
