The article critiques the scholarly emphasis on the centrality of West-Central Africans in the Haitian Revolution. It argues that two highly influential articles published 30 years ago by John Thornton greatly exaggerated the presence of such “Congos” in the colony, and overstated that of Africans in general. Amplified in subsequent works by Thornton and others, this exaggeration has become the prevailing orthodoxy and the issue has gone entirely unnoticed down to today. To make its point, the article draws on a data set of more than 31,000 enslaved workers of known origin and it attempts to calculate population change on the eve of the revolution. It lays out the way the ethnic composition of the black population varied by crop type and region, and produces for the first time estimates for the whole of Saint Domingue. It additionally makes two excursions into African studies. The first is to investigate the ethnic/geographic origins of the “Congos.” The second relates to the nature of slavery in West-Central Africa and certain items of Kikongo vocabulary. This forms part of a critique of an ambitious article by James Sweet concerning the influence of Kongolese in Saint-Domingue that constitutes the article's final section.
From Iran and Mozambique to France’s Gilets jaunes, consumer energy protests are ubiquitous today. Little historical scholarship has so far explored such “fuel riots,” the problematic moniker bestowed by contemporary policy scholars. This article argues for disaggregating the homogenous crowd of so-called rioters, instead analyzing why particular socioeconomic groups persistently take to the streets. To do this, it sketches an energy-centered approach to class with both structural and subjective axes. This analytic is applied to a comparative history of two of the best-documented energy protests of the last half-century. During the 1970s, independent truckers blocked American highways to protest the high price of motor fuel. A decade later, half a million North Indian farmers mobilized to demand cheaper and more reliable electricity. Half a world apart, the two movements shared key characteristics. They were the expression of specific class fractions whose material interests were conditioned by heavy dependence on state-mediated energy supplies. Awkwardly located between big capital and wage labor, both truckers and farmers owned stakes in the carbon-intensive means of production that left them exposed to volatility in energy quality and pricing. Both mobilized in reaction to perceived breaches of state-centered moral economies of energy which threatened this dependence, leveraging their power to interrupt supplies within the circulatory systems of fossil fuel society. Even as both movements failed in their own terms, their political resistance helped to lock in place consumer subsidies for cheap carbon-intensive energy. Such energy protests deserve a central role in our environmental histories of fossil fuel society.
This article considers the possibility that the emphasis we place on composers developing an artistic voice might be unhelpful for making good pieces. I look at what constitutes an artistic voice and consider pros and cons for having a voice. As an alternative I examine strengths and weaknesses for being a capricious composer, which I define as a willingness to explore different compositional avenues without concern for constructing a consistent body of work. My objective is not to discredit composers who have a strong voice, but rather to loosen the grip of the single-voiced model that dominates the value system of new music.
In the Salish Sea region, labret adornment with lip plugs signify particular identities, and they are interpreted as emblematic of both membership in horizontal relationships and achieved status for traditional cultures associated with labret wearing on the Northwest Coast (NWC) of North America. Labrets are part of a shared symbolic language in the region, one that we argue facilitated access to beneficial horizontal relationships (e.g., Angelbeck and Grier 2012; Rorabaugh and Shantry 2017). We employ social network analysis (SNA) to examine labrets from 31 dated site components in the Salish Sea region spanning between 3500 and 1500 cal BP. Following this period, the more widely distributed practice of cranial modification as a social marker of status developed in the region. The SNA of labret data shows an elaboration and expansion of antecedent social networks prior to the practice of cranial modification. Understandings of status on the NWC work backward from direct contact with Indigenous societies. Labret wearing begins at the Middle-Late Holocene transition, setting an earlier stage for the horizontal social relationships seen in the ethnohistoric period. These findings are consistent with the practice as signifying restricted group membership based on affinal ties and achieved social status.
Why might female leaders of democratic countries commit more money, equipment, soldiers, and other resources to interstate conflicts than male leaders? We argue that gender bias in the process of democratic election helps explain this behavior. Since running for office is generally more costly for women than for men, only women who place a higher value on winning competitions will choose to run. After election, they also devote more resources to pursuing victory in conflict situations. To provide microfoundational evidence for this claim, we analyze data from an online laboratory game featuring real-time group play in which participants chose to run for election, conducted a simple campaign, and represented their group in a contest game if elected. Women with a higher nonmonetary value to winning were more likely to self-select into candidacy, and when victorious, they spent more resources on intergroup contests than male elected leaders. The data suggest that electoral selection plays an important role in observed differences between male and female leaders in the real world.
For an action of a finite group on a finite EI quiver, we construct its ‘orbifold’ quotient EI quiver. The free EI category associated to the quotient EI quiver is equivalent to the skew group category with respect to the given group action. Specializing the result to a finite group action on a finite acyclic quiver, we prove that, under reasonable conditions, the skew group category of the path category is equivalent to a finite EI category of Cartan type. If the ground field is of characteristic $p$ and the acting group is a cyclic $p$-group, we prove that the skew group algebra of the path algebra is Morita equivalent to the algebra associated to a Cartan matrix, defined in [C. Geiss, B. Leclerc, and J. Schröer, Quivers with relations for symmetrizable Cartan matrices I: Foundations, Invent. Math. 209 (2017), 61–158]. We apply the Morita equivalence to construct a categorification of the folding projection between the root lattices with respect to a graph automorphism. In the Dynkin cases, the restriction of the categorification to indecomposable modules corresponds to the folding of positive roots.
The dynamics of fluid-conveying pipelines with different shapes has received extensive research attention. Significant wall shear stress and flow separation occur when the fluid flows through pipelines with various curvatures. These phenomena trigger pipeline vibration, the generation of mechanical and hydrodynamic noise, damage, and even the rupture of the pipeline. However, previous studies have not considered the mechanism of internal pipeline flow to eliminate flow separation and the generation of secondary flow inside bent pipelines by redirecting and manipulating the flow. To steer the fluid flow, a ‘hydrodynamic transformation strategy’ based on the metamaterial technology is proposed for the first time in this work; through this strategy, the fluid in pipelines can be made to flow along trajectories that are always parallel to the central axis of the bent pipelines. Interestingly, this innovative method can effectively eliminate the elbow-induced secondary flow and prevent the generation of a pressure gradient toward the pipeline wall. Using the soft lithography technology or the three-dimensional printing technology, the hydrodynamic metamaterial microstructure required to manipulate the fluid flow path in actual engineering applications can be achieved. Our work paves the way for developing new approaches for controlling the flow characteristics and reducing the turbulence intensity of the fluid flowing in pipelines with elbows and corners.
First Corinthians 6.1–6 is consistently read as a Pauline criticism directed against members of the Pauline ekklēsia in Corinth, taking each other to Roman courts. I argue that this understanding of 1 Cor 6.1–6 is implausible in light of practices of Roman law in the provinces and in the colonies. Within a formal court procedure, the Corinthians would not have had the freedom to appoint their own judges, as Paul's language implies. I suggest instead that it is private arbitration which Paul criticises. Papyri dealing with private arbitration and mediation support this reading. Much of Paul's legal terminology in the passage is found in these papyri, making private arbitration a highly plausible suggestion. The suggested reading points to the community's good social ties with the pagan population in the city. It also depicts Paul as working within the framework of Roman law rather than against it. The article exemplifies the benefits of integrating up-to-date studies of Roman law in New Testament Studies.
Islamic veiling has attracted a remarkable degree of international and domestic attention in the current political climate. In the popular and political climate, the argument for social cohesion (or living together) is frequently invoked to justify bans on wearing Islamic veils. For example, the social cohesion argument was widely used in parliamentary debates leading up to the bans on wearing Islamic full-face veils (such as burqa or niqab) in France and Belgium. In response to the French and Belgian bans, the European Court of Human Rights has ruled that a ban on wearing Islamic full-face veils is justified on the grounds of living together, rulings that many academic circles have criticized. Yet in this extensive commentary on the bans of Islamic veiling, one important question remains unanswered: Is social cohesion (or living together) a valid argument for banning the wearing of Islamic veils? The author explores this question through the lens of the European human rights framework and analyzes the ECtHR’s approach to French and Belgian anti-veil legislation enacted on the grounds of social cohesion.
