Introduction to Gravity Models of Migration & Trade

This lesson introduces gravity models as a means for determining the probable distribution of entities across space in historical datasets. It does so through a case study of historical migration patterns.Peer reviewe

The Black Londoner Experience: Exploring Black Life through Records of the Court, 1720-1840

Black Londoners have lived in the city for centuries. This collection brings 10 Black London lives together in an accessible volume to share the diversity of their experiences in the eighteenth and early nineteenth centuries with new readers. Drawing on the records of the Old Bailey criminal courthouse, these ten carefully selected trials have been chosen to show some of the breadth of Black experience in London during the age of enslavement (c. 1720-1840). The volume includes Black victims, witnesses, and defendants; men, women, and children; sailors, servants, and entertainers; locals, immigrants, and visitors. Some were treated well by the justice system, and others were met with cruelty. Each had their own experience. While the volume contains details of crime and conflict, crime is not the sole focus. The sources also give us glimpses into the daily lives of these Black individuals as they interacted with the city and its inhabitants. We learn where these Black people spent their time, with whom, doing what, and sometimes even what they had in their pockets. Each of the ten cases has been accessibly formatted for classroom use or personal study, and features illustrations by Manon Wright. The sources are arranged like plays, making them easy to read aloud as a means of better understanding the theatre of the courtroom and the power dynamics at play. Dr Crymble offers notes and reflections on tricky or foreign concepts in each case, as well as issues that he has noted through experience that students often misinterpret by making modern assumptions about the past

A Comparative Approach to Identifying the Irish in Long Eighteenth-Century London

Historians seeking to identify the Irish have overwhelmingly relied upon nominal record linkage, thus limiting studies to periods and contexts in which corroborating records exist. Surname analysis provides an alternative: a subset of 283 Irish surnames was able to correctly isolate 40 percent of known Irish individuals across thousands of entries, which is sufficient for sampling the Irish in demographic studies. This conclusion was based on an analysis of 278,949 names from the London area in the 1841 census, and was tested and refined against 42,248 historical records pertaining to the poor in London between 1777 and 1820

Digital library search preferences amongst historians and genealogists: British History Online user survey

This paper presents the results of a study of 1,439 users of British History Online (BHO). BHO is a digital library of key printed primary and secondary sources for the history of Britain and Ireland, with a principal focus on the period between 1300 and 1800. The collection currently contains 1,250 volumes, and 120,000 web pages of material. During a website rebuild in 2014, the project team asked its registered users about their preferences for searching and browsing the content in the collection. Respondents were asked about their current search and browsing behaviour, as well as their receptiveness to new navigation options, including fuzzy searching, proximity searching, limiting search to a subset of the collection, searching by publication metadata, and searching entities within the texts such as person names, place names, or footnotes. The study provides insight into the unique and often converging needs of the site’s academic and genealogical users, noting that the former tended to respond in favour of options that gave them greater control over the search process, whereas the latter generally opted for options to improve the efficacy of targeted keyword searching. Results and recommendations are offered for managers of similar digitally-driven repositories interested in understanding and improving user experience.Peer reviewedFinal Published versio

The decline and fall of an early modern slum: London's St Giles 'Rookery', c. 1550–1850

The Rookery of London's St Giles-in-the-Fields became the city's most notorious slum by the eighteenth century. This article asks why? Why there, why then and why for so long? Building on existing research about urban development and the failure of local government, by considering the geography, economics and legal influences acting upon the space and the people who interacted with it over the long durée, it becomes clear that the Rookery of St Giles-in-the-Fields was always high risk because of happenstance of geography, but that a lack of leadership from its owners and a system of urban upkeep that distributed responsibility too widely led to its longevity and the depth of its misfortune

Towards reliable correlation of microporous layer physical characteristics and PEMFC electrochemical performance

Includes bibliographical references.Polymer electrolyte membrane (PEM) fuel cells are promising clean energy alternatives to non - sustainable fossil fuels. During fuel cell operation, external humidification of reactant gases is typically required in order to increase PEM conductivity for improved performance. However, the use of external humidification is costly and increases system complexity. Recently it has been found that by including a cathode microporous layer (MPL) in the membrane electrode assembly (MEA) , performance under dry conditions (no external humidification) can be significantly improved . However, the precise function of the MPL is not well understood and therefore there is little theoretical basis to optimisation of physical properties. One possible reason for this lack of understanding is the absence of a well-established fabrication, characterization and electrochemical testing methodology for MPL research. In particular, current research places little emphasis on the effect of MEA variance on the uncertainty in MPL electrochemical performance results. In this study a methodology is developed for fabricating, characterizing and testing MPLs to accurately correlate physical properties with in-situ electrochemical performance. MPLs of two significantly different thicknesses (approximately 20 and 50 μm in the thickest regions) were fabricated in - house using a doctor blade method and varying the ink composition. The pore structure and thickness of MPLs were characterized by mercury intrusion porosimetry (MIP), scanning electron microscopy (SEM) and X-ray micro computed tomography (μCT)
