Rethinking the fall of the planter class

This issue of Atlantic Studies began life as a one-day conference held at Chawton House Library in Hampshire, UK, and funded by the University of Southampton. The conference aimed, like this issue, to bring together scholars currently working on the history of the British West Indian planter class in the eighteenth and nineteenth centuries and to discuss how, when, and why the fortunes of the planters went into decline. As this introduction notes, the difficulties faced by the planter class in the British West Indies from the 1780s onwards were an early episode in a wider drama of decline for New World plantation economies. The American historian Lowell Ragatz published the first detailed historical account of their fall. His work helped to inform the influential arguments of Eric Williams, which were later challenged by Seymour Drescher. Recent research has begun to offer fresh perspectives on the debate about the decline of the planters, and this collection brings together articles taking a variety of new approaches to the topic, encompassing economic, political, cultural, and social histor

Inherent High Correlation of Individual Motility Enhances Population Dispersal in a Heterotrophic, Planktonic Protist

Quantitative linkages between individual organism movements and the resulting population distributions are fundamental to understanding a wide range of ecological processes, including rates of reproduction, consumption, and mortality, as well as the spread of diseases and invasions. Typically, quantitative data are collected on either movement behaviors or population distributions, rarely both. This study combines empirical observations and model simulations to gain a mechanistic understanding and predictive ability of the linkages between both individual movement behaviors and population distributions of a single-celled planktonic herbivore. In the laboratory, microscopic 3D movements and macroscopic population distributions were simultaneously quantified in a 1L tank, using automated video- and image-analysis routines. The vertical velocity component of cell movements was extracted from the empirical data and used to motivate a series of correlated random walk models that predicted population distributions. Validation of the model predictions with empirical data was essential to distinguish amongst a number of theoretically plausible model formulations. All model predictions captured the essence of the population redistribution (mean upward drift) but only models assuming long correlation times (minute), captured the variance in population distribution. Models assuming correlation times of 8 minutes predicted the least deviation from the empirical observations. Autocorrelation analysis of the empirical data failed to identify a de-correlation time in the up to 30-second-long swimming trajectories. These minute-scale estimates are considerably greater than previous estimates of second-scale correlation times. Considerable cell-to-cell variation and behavioral heterogeneity were critical to these results. Strongly correlated random walkers were predicted to have significantly greater dispersal distances and more rapid encounters with remote targets (e.g. resource patches, predators) than weakly correlated random walkers. The tendency to disperse rapidly in the absence of aggregative stimuli has important ramifications for the ecology and biogeography of planktonic organisms that perform this kind of random walk

Chapitre 3. La réforme sans la révolution : l’abolitionnisme selon Tocqueville

Note portant sur l'auteur Durant les derniers mois de 1834, alors qu’Alexis de Tocqueville terminait les dernières révisions de De la Démocratie en Amérique, une société française pour l’abolition de l’esclavage voyait le jour à Paris. Ce qui déclencha sa création fut la mise en œuvre de l’émancipation des esclaves des colonies britanniques en août 1834. La parution du livre de Tocqueville coïncidait parfaitement avec sa vieille ambition de mêler accomplissement littéraire et activité politiq..

Oral History Interview: Seymour Drescher (1376)

Interviewed by: Anita HectIn his October 2010 with Anita Hecht for the George L. Mosse Program in History Materials, Seymour Drescher discusses interacting with George L. Mosse as a student, colleague and friend. He discusses how Mosse influenced his own academic work and teaching style. Drescher also describes his background growing up in the Bronx, New York
