Autofiction's Interrogation of Neoliberal Subjectivity

Recent scholarship has highlighted the affinity between autofiction—a development in the contemporary novel that incorporates a fictionalized version of the author in the work—and the neoliberal economy. Through readings of contemporary autofictional novels by Nicole Krauss and Sheila Heti, this essay argues that autofiction—in addition to being a method by which the author can respond to the injunction to develop his or her own portfolio of human capital—is a form that interrogates the animating logics behind the contemporary subject of capital. Heti’s How Should a Person Be? (2010) dramatizes the formation of the artist as neoliberal subject as the adoption of enterprise unification of purpose in order to function within the competitive field. Motherhood (2018) describes a writer in her late thirties who stages a confrontation between the cultural directive to have children and the demands of a subjectivity marked by the injunction to achieve continuous progress, even when none is available. Krauss’s Forest Dark. (2017) turns the critical lens back onto autofiction itself, pairing alternating narratives that coalesce to form a critique of autofiction’s ambiguous capacity to alter the author’s public image. All three novels conclude with an ambivalence toward the continual making of self that lies at the heart of both the subject of late capitalism and the autofictional gesture, and in so doing, reject the ubiquity of growth narratives in favor of a depiction of self-investment as a recursive, self-perpetuating circuit

U–Pb Geochronology and Stable Isotope Geochemistry of Terrestrial Carbonates, Lower Cretaceous Cedar Mountain Formation, Utah: Implications for Synchronicity of Terrestrial and Marine Carbon Isotope Excursions

The terrestrial Lower Cretaceous Cedar Mountain Formation, Utah, is a critical archive of paleoclimate, tectonics, and vertebrate ecology and evolution. Early Cretaceous carbon cycle perturbations associated with ocean anoxia have been interpreted from this succession, as expressed in stable carbon isotopes. However, refining the timing of the observed stable isotope excursions remains a key challenge in understanding how marine anoxia affects the Earth system, and is ultimately recorded in the terrestrial realm. The geochronology and geochemistry of a terrestrial carbonate near the base of this succession, which potentially records the Ap7 global carbon isotope excursion, is studied here. Petrographic and geochemical analyses are used to test plausible mechanisms for U incorporation into the calcite lattice in this sample. Using these methods, the hypothesis that the incorporation of U was at or close to the timing of carbonate precipitation is evaluated. U–Pb geochronology of calcite indicates a plausible Early Cretaceous age. However, comparison of the new U–Pb ages of calcite with detrital zircon maximum depositional ages immediately beneath the studied sample indicates a disparity in the apparent sedimentation rates if both types of geochronologic information are interpreted as reflecting the timing of sediment deposition. The totality of data supports an early, and high-temperature, diagenetic timing of U incorporation, with potential for minor leaching of U in subsequent fluid–rock interaction. The most likely mechanism for U transport and immobilization in these samples is hydrothermal fluid–rock interaction. Therefore, the radiometric ages, and corresponding stable isotope composition of U-bearing carbonate domains in this sample, indicate early subsurface fluid–rock interactions and not a record of atmosphere–soil geochemical reactions
