Masculinity as Governance: police, public service and the embodiment of authority, c. 1700-1850
About the book: Public Men offers an introduction to an exciting new field: the history of masculinities in the political domain and will be essential reading for students and specialists alike with interests in gender or political culture. By building upon new work on gender and political culture, these new case studies explore the gendering of the political domain and the masculinities of the men who have historically dominated it. As such, Public Men is a major contribution to our understanding of the history of Britain between the Eighteenth and the Twentieth centuries
Age-related changes in global motion coherence: conflicting haemodynamic and perceptual responses
Our aim was to use both behavioural and neuroimaging data to identify indicators of perceptual decline in motion processing. We employed a global motion coherence task and functional Near Infrared Spectroscopy (fNIRS). Healthy adults (n = 72, 18-85) were recruited into the following groups: young (n = 28, mean age = 28), middle-aged (n = 22, mean age = 50), and older adults (n = 23, mean age = 70). Participants were assessed on their motion coherence thresholds at 3 different speeds using a psychophysical design. As expected, we report age group differences in motion processing as demonstrated by higher motion coherence thresholds in older adults. Crucially, we add correlational data showing that global motion perception declines linearly as a function of age. The associated fNIRS recordings provide a clear physiological correlate of global motion perception. The crux of this study lies in the robust linear correlation between age and haemodynamic response for both measures of oxygenation. We hypothesise that there is an increase in neural recruitment, necessitating an increase in metabolic need and blood flow, which presents as a higher oxygenated haemoglobin response. We report age-related changes in motion perception with poorer behavioural performance (high motion coherence thresholds) associated with an increased haemodynamic response
On the Inverse Problem of Binocular 3D Motion Perception
It is shown that existing processing schemes of 3D motion perception such as interocular velocity difference, changing disparity over time, as well as joint encoding of motion and disparity, do not offer a general solution to the inverse optics problem of local binocular 3D motion. Instead we suggest that local velocity constraints in combination with binocular disparity and other depth cues provide a more flexible framework for the solution of the inverse problem. In the context of the aperture problem we derive predictions from two plausible default strategies: (1) the vector normal prefers slow motion in 3D whereas (2) the cyclopean average is based on slow motion in 2D. Predicting perceived motion directions for ambiguous line motion provides an opportunity to distinguish between these strategies of 3D motion processing. Our theoretical results suggest that velocity constraints and disparity from feature tracking are needed to solve the inverse problem of 3D motion perception. It seems plausible that motion and disparity input is processed in parallel and integrated late in the visual processing hierarchy

Introduction: John Morrill and the experience of revolution
When John Morrill began his research career the most influential writing about mid-seventeenth-century England was essentially concerned with modernization, and, even in non-Marxist explanations, contained a strong strain of materialism. This was a prominent feature of the sometimes vituperative exchanges of the gentry debate, and John's first piece of extended writing about seventeenth-century England was written in response to that controversy; it was a long essay, composed during a summer vacation, which examined the relationship between the fortunes of particular gentry families and their Civil War allegiance. His interest in local realities, however, quickly gave rise to dissatisfaction with the broad categories of analysis with which the gentry controversy was engaged. By the time that he published the monograph based on his Oxford D.Phil. thesis, in 1974, he concluded (among other things) that ‘the particular situation in Cheshire diffracted the conflicts between King and Parliament into an individual and specific pattern. As a result all rigid, generalized explanations, particularly of the socio-economic kind, are unhelpful if not downright misleading.’ A desire to do better than these generalizations has driven his work ever since, and has thereby provided a huge stimulus to scholars of early modern England. His doctoral study of Cheshire marked the beginning of the first of three overlapping but distinct phases in the development of his work, in each of which he has been a leading figure

Preface
This book is a tribute to John Morrill by a number of his former students, published to coincide with John's sixty-fifth birthday, an appropriate moment to celebrate his extraordinary achievements as a teacher and scholar. It is very difficult to capture the career and influence of such an eminent and influential figure, but a crucial feature of John's contribution is that it has been made not simply through his own writing but across a much broader front, particularly through his teaching and wider advocacy for both his field and his profession. This volume is edited by two of his former students, and all the contributions are written by his students engaging with central themes in his work; that is, we hope, a fitting way to mark this distinctive contribution. John's teaching has always moved in step with his research interests. His advanced courses engaged successively with the study of English government, the British problem, the life and reputation of Oliver Cromwell and latterly with the Irish rebellion of 1641, while his outline courses followed a similar trajectory, also taking in his thesis about the religious roots of seventeenth-century political conflict. Always the concern with personalities came through, sometimes explicitly, as in a 1995 course on ’Stuart politics and personalities: eight case studies’. The overview of John's published work offered in the introduction therefore summarizes an oeuvre that has unfolded in symbiosis with the teaching that means so much to him
