Asexual Dramaturgies: Reading For Asexuality In The Western Theatrical Canon, Anna Maria Ruffino Broussard Nov 2022

Asexual Dramaturgies: Reading For Asexuality In The Western Theatrical Canon, Anna Maria Ruffino Broussard

LSU Doctoral Dissertations

Asexuality has recently gained recognition and visibility as a legitimate sexual orientation and identity standpoint that is usually defined as lacking sexual desire for any gender. Popular culture and the academy have both seen the emergence of a robust conversation about the definition and import of asexuality, recognizing the term as an umbrella concept covering an ever-diversifying array of identities. Within the nascent critical discourse on asexuality, theorists have sought to identify asexuality as a sexual orientation, to rethink our society’s sexual normativity, and to question compulsory sexuality, or the assumption that sexual desire is intrinsic to all people, thus …

Migration And Displacement In Twenty-First Century Magical Realist Fiction, Laura Duncan Fontenot

LSU Doctoral Dissertations

In “Migration and Displacement in Twenty-First Century Magical Realist Fiction” I discuss identity development and the search for belonging of displaced people within twenty-first century magical realist novels. In each instance, the characters undergo some form of change heralded by a magical moment or moments. The “magic” allows the authors to literalize underlying cultural tensions by physically altering some aspect of a character. The changes are not mere metaphors, they are literal, bodily transformations. The first stage of this process are magical thresholds that allow passage in space and time far beyond the conventions of reality. A magical threshold literalizes …

Assessment And Constraint Of Mesozooplankton In Cmip6 Earth System Models, C. M. Petrik, J. Y. Luo, R. F. Heneghan, J. D. Everett, C. S. Harrison, A. J. Richardson

Faculty Publications

Although zooplankton play a substantial role in the biological carbon pump and serve as a crucial link between primary producers and higher trophic level consumers, the skillful representation of zooplankton is not often a focus of ocean biogeochemical models. Systematic evaluations of zooplankton in models could improve their representation, but so far, ocean biogeochemical skill assessment of Earth system model (ESM) ensembles have not included zooplankton. Here we use a recently developed global, observationally based map of mesozooplankton biomass to assess the skill of mesozooplankton in six CMIP6 ESMs. We also employ a biome-based assessment of the ability of these …

Sustainable buildings are designed to reduce energy use and other environmental impacts and to provide indoor environmental conditions that maximize well-being and satisfaction among building occupants. However, occupants' comfort in and satisfaction with such buildings has been inconsistent. Evidence indicates occupants' expectations of indoor building environments influence their perceptions of climatic conditions (e.g., temperature) and comfort while in buildings. Accordingly, it is important to better understand a priori expectations associated with sustainable buildings. An online experiment examined the influence of exposure to a depiction of a sustainable vs. a conventional building on a priori expectations of indoor environmental conditions/quality (IEQ) …
