Playing Proverbs With Madame De Genlis, Rebecca Cypess Dec 2024

Playing Proverbs With Madame De Genlis, Rebecca Cypess

ABO: Interactive Journal for Women in the Arts, 1640–1830

The theatrical genre known as the proverbe dramatique, which flourished as a pastime of French high society during the late eighteenth century, has often been understood through the written exemplars left by the author and artist Louis Carrogis, known as Carmontelle. Yet Carmontelle’s literary contributions to the genre have obscured the vast range of activities known as jouer des proverbes (playing proverbs)—activities associated especially with women—which included conversational games, pantomime, poetry, dance, and music making. Attending to the many descriptions of jouer des proverbes left by Stéphanie Félicité Ducrest de Saint-Aubin, the Com­tesse de Genlis, reveals that the literary …


The Sounds Of Madame Geoffrin’S Salon, Melanie Conroy Dec 2024

The Sounds Of Madame Geoffrin’S Salon, Melanie Conroy

ABO: Interactive Journal for Women in the Arts, 1640–1830

Salons were core institutions of the eighteenth-century European social calendar, especially in Paris. Literary performances and philosophical conversation were the core activities of many of these gatherings. What did conversation and literary readings actually sound like at these events? To what extent were voices audible to everyone in the room, or too muffled or far away to be heard? What was the impact of the ambiance or of ephemeral sound on the reading or reception of the hearing? Using textual descriptions, paintings, and architectural information, I reconstruct two legendary readings of eighteenth-century texts, Voltaire’s L’Orphélin de la Chine and Marmontel's …

The Enactive Nature Of The Relationship Between Criticism And Aesthetics: From Practice To Theory To Pedagogy, Ivan Magrin-Chagnolleau

Presidential Fellows Articles and Research

This article delves into the intricate relationship between criticism and aesthetics, emphasizing its enactive nature. It explores how this relationship informs pedagogy and has culminated in the creation of an innovative undergraduate aesthetics course centered around the practice of writing critiques. Moreover, it illustrates the dynamic process through which practice gives rise to theory, subsequently influencing pedagogical approaches, and, intriguingly, circling back to practice. To elucidate this flow of ideas across the realms of practice, theory, and pedagogy, we introduce several key concepts. These include the paradigm of creation research, also known as practice as research, which forms the foundation …


Hauntings Of Publication Deaths, Possibilities For Our Academic Present, Kathleen (Kaye) A. Hare, Amber Moore Dec 2024

Hauntings Of Publication Deaths, Possibilities For Our Academic Present, Kathleen (Kaye) A. Hare, Amber Moore

Journal of Feminist Scholarship

In this paper, we use a feminist dialogue to query publication deaths that haunt us. We ruminate on respective past publications that remain unread and uncited, despite encapsulating defining events in our development as scholars. For Author Kaye Hare this was an affective narrative that troubled a seemingly ideal moment of public scholarship; for Author Amber Moore, this was a hard-fought analysis of precarious intersectional feminist resistance in popular culture. Inspired by the horror-film genre “spectral incognizance,” we methodologically deploy a multivocal dialogical structure based on multiple revisitings that attenuate anxieties of metaphorical publication death, before revealing that this death …


Using Gis To Visualize Daily Routines At The Neighborhood And Household Scales: A Feminist Approach Using A Nineteenth-Century Diary, Sterling D. Quinn Dec 2024

Using Gis To Visualize Daily Routines At The Neighborhood And Household Scales: A Feminist Approach Using A Nineteenth-Century Diary, Sterling D. Quinn

Journal of Feminist Scholarship

Feminist scholars in the discipline of geography have noted the ways that routine activities at the household and neighborhood scales contribute to power relations and identity formation. Geographic information systems (GIS), with their ability to create multiple visual representations of people’s experiences in space at any scale, hold great potential for revealing these local processes and patterns that are often lost or invisible in broader historical narratives, especially when they pertain to women and children. This article contributes an example by using GIS to encode and map everyday events in a diary kept by Elisabeth Koren, a nineteenth-century Norwegian immigrant …

Aggressive breast cancers often fail or acquire resistance to radiotherapy. To develop new strategies to improve the outcome of aggressive breast cancer patients, we studied how PARP inhibition radiosensitizes breast cancer models to proton therapy, which is a radiotherapy modality that generates more DNA damage in the tumor than standard radiotherapy using photons. Two human BRCA1-mutated breast cancer cell lines and their isogenic BRCA1-recovered pairs were treated with a PARP inhibitor and irradiated with photons or protons. Protons (9.9 and 3.85 keV/µm) induced higher cell kill independent of BRCA1 status. PARP inhibition amplified the cell kill effect to both photons …

Spectral Differencing Of Glories Reflects Cloud Droplet Size Distribution, Ilan Koren, Alex Kostinski, Uri Wollner

Michigan Tech Publications

The glory, a striking optical phenomenon seen from space in unpolarized satellite images can be mapped onto the cloud's droplet sizes with a characteristic scale of 10 (Formula presented.). Such a mapping allows us to infer the mean and variance of the cloud droplets' radius, an important property that has remained elusive and inaccessible to passive unpolarized satellite sensing. Here, we propose a simple and robust polarization-like differential approach to map the glory's spectral properties to the desired moments of the droplet size distribution. By taking the differences between two spectrally close channels, we reduce multiple scattering contributions and amplify …
