Technology, Inventing, and Patenting

The classic narrative of technology, invention, and patenting in the Atlantic world before 1850 focused on the industrialization of the Atlantic seaboard in Britain and the United States, with the adoption of mechanized cotton and wool textile production based on water power and then steam power, and on the development of related heavy industries. Other parts of the region appeared mainly as suppliers of raw materials, such as cotton from the American South, or as markets for the products of mechanized manufacture. While still a powerful narrative, most recent scholarship has reassessed or nuanced key elements, moving away from the traditional story of “heroic” inventors and toward more complex stories of supply and demand, including the capacity of economies and societies in the Atlantic world to supply the technical, commercial, and financial skills needed for invention and innovation, and the changing patterns of consumption and retail that created demand. Attention has also focused on innovation in other sectors, including armament production, transportation and public utilities, and the impact that innovation had upon the lives of those involved in it. Equally important has been a wider regional focus that now includes the southern territories of the Americas as important sites for innovation. Both Adam Smith and Karl Marx dismissed these areas of plantation agriculture as inefficient and irrelevant, a dead end compared to the centers of commerce and industry. Recent work has revised this by demonstrating the quasi-industrial processes required to process sugar, cotton, tobacco, indigo, and other tropical commodities; the scope for technological improvement; and the vast profits that enabled planters to invest in this technology. Leading plantation colonies such as Jamaica in the 18th century and Cuba in the early 19th century were among the first adopters of the steam engine outside Europe, where it had an equally transformative social and economic impact.

Contrasting northern and southern European winter climate trends during the Last Interglacial

The Last Interglacial (LIG; 130–115 ka) is an important test bed for climate science as an instance of significantly warmer than preindustrial global temperatures. However, LIG climate patterns remain poorly resolved, especially for winter, affected by a suite of strong feedbacks such as changes in sea-ice cover in the high latitudes. We present a synthesis of winter temperature and precipitation proxy data from the Atlantic seaboard of Europe, spanning from southern Iberia to the Arctic. Our data reveal distinct, opposite latitudinal climate trends, including warming winters seen in the European Arctic while cooling and drying occurred in southwest Europe over the LIG. Climate model simulations for 130 and 120 ka suggest these contrasting climate patterns were affected by a shift toward an atmospheric circulation regime with an enhanced meridional pressure gradient and strengthened midlatitude westerlies, leading to a strong reduction in precipitation across southern Europe.

Airborne measurements of fire emission factors for African biomass burning sampled during the MOYA campaign

Airborne sampling of methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and nitrous oxide (N2O) mole fractions was conducted during field campaigns targeting fires over Senegal in February and March 2017 and Uganda in January 2019. The majority of fire plumes sampled were close to or directly over burning vegetation, with the exception of two longer-range flights over the West African Atlantic seaboard (100–300 km from source), where the continental outflow of biomass burning emissions from a wider area of West Africa was sampled. Fire emission factors (EFs) and modified combustion efficiencies (MCEs) were estimated from the enhancements in measured mole fractions. For the Senegalese fires, mean EFs and corresponding uncertainties in units of gram per kilogram of dry fuel were 1.8±0.19 for CH4, 1633±171.4 for CO2, and 67±7.4 for CO, with a mean MCE of 0.94±0.005. For the Ugandan fires, mean EFs were 3.1±0.35 for CH4, 1610±169.7 for CO2, and 78±8.9 for CO, with a mean modified combustion efficiency of 0.93±0.004. A mean N2O EF of 0.08±0.002 g kg−1 is also reported for one flight over Uganda; issues with temperature control of the instrument optical bench prevented N2O EFs from being obtained for other flights over Uganda. This study has provided new datasets of African biomass burning EFs and MCEs for two distinct study regions, in which both have been studied little by aircraft measurement previously. These results highlight the important intracontinental variability of biomass burning trace gas emissions and can be used to better constrain future biomass burning emission budgets. More generally, these results highlight the importance of regional and fuel-type variability when attempting to spatially scale biomass burning emissions. Further work to constrain EFs at more local scales and for more specific (and quantifiable) fuel types will serve to improve global estimates of biomass burning emissions of climate-relevant gases.

The Mediterranean World and the ‘Turk’ in Shakespeare’s Representation of the British Empire

This research explores Shakespeare’s representation of the so-called British Empire in its contact with other jostling empires, most notably the Ottoman Empire in the Mediterranean. To this end, four of Shakespeare’s Mediterranean plays Othello, the Moor of Venice (1603), The Merchant of Venice (1596), The Tempest (1611), and Cymbeline (1611) are taken understudy. By considering the Postcolonial historicist approach developed by literary scholars such as Stephen Greenblatt and Edward Said, the research argues that the issues of imperial relationships in Shakespeare are not solely centered on the transatlantic colony of Virginia, but it was also extended to the Mediterranean basin. The latter, during Tudor England and, later, Stuart Britain had much more trade and diplomatic activity than on the Atlantic seaboard. This economic activity created a cosmopolitan zone of contact wherein people of the Orient elbowed people from the West. This encounter gave rise to a pre-modern form of Orientalism, which is reflected in Shakespeare’s celebration of marital-cum-political endogamous relationships in his four plays mentioned earlier.

Starring Women

Star actresses and dancers were among the most publicly visible, celebrated, and often polarizing female public figures in the early United States. This book examines the careers and celebrity of the women and girls from Europe and America whose fame drove the growth and transformation of theater between 1790 and 1850 from the Atlantic seaboard to the trans-Appalachian West. Starring women introduced new repertoire—melodramas, breeches roles, dance pantomime and ballet—that catalyzed debates about social ownership of American culture, regional and national identity, and women’s place in public life. This book transforms existing understandings of early U.S. theater and culture by examining a broad cohort of understudied figures and argues that women stars were vital to the development of transatlantic and U.S. entertainment, celebrity culture, and gender ideology. Most significantly, starring women lived and performed the tensions and contradictions of changing nineteenth-century gender roles. As this book demonstrates, even while they achieved unprecedented levels of wealth and prominence through the “starring system,” the patriarchal family structures that governed women’s lives and careers conditioned their participation in the industry. The celebrity culture that expanded from the 1820s demanded that starring women conform to new standards of sentimental domestic femininity, even as the structural realities of their lives defied such standards. Starring women were exceptional figures who mapped the margins of a narrowing white middle-class domestic ideal.

Coastal Resilience Against Storm Surge from Tropical Cyclones

It is well known that seawalls are effective at stopping common storm surges in urban areas. This paper examines whether seawalls should be built to withstand the storm surge from a major tropical cyclone. We estimate the extra cost of building the wall tall enough to stop such surges and the extra flood benefit of this additional height. We estimate the surge probability distribution from six tidal stations spread along the Atlantic seaboard of the United States. We then measure how valuable the vulnerable buildings behind a 100 m wall must be to justify such a tall wall at each site. Combining information about the probability distribution of storm surge, the average elevation of protected buildings, and the damage rate at each building, we find that the value of protected buildings behind this 100 m wall must be in the hundreds of millions to justify the wall. We also examine the additional flood benefit and cost of protecting a km2 of land in nearby cities at each site. The density of buildings in coastal cities in the United States are generally more than an order of magnitude too low to justify seawalls this high. Seawalls are effective, but not at stopping the surge damage from major tropical cyclones.
