- Description/Abstract:
- Latent variables and causal inference are central to implementing empirical research and advancing substantive theory across the social sciences. Conventional latent variable frameworks such as structural equation modeling (SEM) are constrained by several simplifying assumptions (e.g., linearity, additivity, correct model specification). In this study, we relax key SEM assumptions by building data adaptive estimation methods for causal inference with latent variables. We developed a theory-driven Targeted After Generative (TAG) learning framework that integrates SEM-informed variational autoencoders (SEM VAEs) with targeted machine learning to estimate the average treatment effect. On the generative side, the SEM VAE encodes theory aligned neural networks that learn latent variable distributions through flexible joint modeling of measurement and structural parameters. On the targeted learning side, we construct an efficient influence function for the treatment effect with the SEM-VAE implied posterior distribution of the latent variables to estimate the average effect. Across simulations, the TAG learning approach outperforms alternative approaches and demonstrates low to no bias even in adverse conditions. TAG learning offers a theory-driven flexible approach with methodological promise for causally interpretable data-adaptive analysis with latent variables. More practically, the framework allows estimation of causal effects involving latent variables even in the presence of unknown functional relationships in the measurement and structural models (e.g., data adaptive effect estimation for nonlinear/nonadditive SEMs).

- Description/Abstract:
- This archeometric study analyzed local clay deposits at the Ingels Family Farm, settled in the Early Nineteenth Century in Bourbon County Kentucky. The redware pottery made on site was bartered and sold in the region, and the clay deposits were also used to make the bricks that constructed the 1820 Ingels family residence, still extant as of May 2026. Numerous materials characterization techniques including XRD, XRF, DTA/TGA, Spectroscopy, wet chemical analysis, and SEM were used to determine the characteristics of the local clay deposit and the identifying characteristics of the redware. The study also tested the wares to determine an approximate firing range, which was consistent with the requirements of low-to-mid fired earthenware. This study was done using archaeological materials from a previous archaeological investigation of the farm, but new material was added with the assistance the USDA Soil Survey Office in Kentucky, who drilled core samples for the project in Spring 2012.

- Description/Abstract:
- Modern industrial equipment are networked to interact with both internal and external systems, enabling automated decision-making with minimal or no human intervention. While this new environment creates efficiencies, it exposes the environment to cyber threats. This chapter explores the use of cybersecurity testbeds to study best practices in architecting and defending environments that contain industrial systems. Cybersecurity testbeds – physical, virtual, and hybrid – are used in different sectors for research and validation. Virtual testbeds hold promise as they enable design flexibility, reconfiguration, and scale to support various types of research studies. This chapter discusses the value of virtual cybersecurity testbeds and demonstrates a case study on the use of virtual testbeds using a simple industrial control system and a common attack. The concepts apply to more complex set ups and more complex attack structures. Virtual cybersecurity testbed can support researchers, practitioners, and educators interested in defending critical infrastructure environments and industrial systems.

- Description/Abstract:
- This project will explore the artist Leonora Carrington’s Self-portrait (Inn of the Dawn Horse, ca. 1937-38) and its relationship to and rejection of the male-centric, sexist ideology of psychoanalysis that governed the Surrealist movement. As outlined in Andre Breton's First Manifesto of Surrealism (1924), Freudian psychoanalysis had a great influence on Breton, the movement's founder (1896-1966). He believed in Freud's tenets and theories regarding dreams and the unconscious as a liberating and radical force that could tear down society’s systems of oppression. Yet there is a willful ignorance in Breton’s philosophy on the deep-rooted misogyny of Freud’s psychology and how the institution of psychoanalysis ignores the realities of female development and existence within inherently sexist societal structures of that period. However, Leonora Carrington rejected psychoanalytic theory as it pertained to her art. She refused to be categorized within sexist ideologies and asserted herself as a creative artist with her own interpretations of her work, positing her own ideologies in the process. She demonstrated her identity through her work and found liberation by developing her own feminist consciousness. Through researching Carrington's work, I want to expand on her ability to challenge the sexist paradigms of Surrealism and to reaffirm how her rejection demonstrates that female nonconformity is not only revolutionary but also necessary for female artistic freedom today. Other scholars have delved into this driving aspect of Carrington’s work but I will be utilizing Helene Cixous’ concept of “ecritutre feminine” in order to demonstrate how Carrington developed a “pictorial language” of her own within her work Self-Portrait (Inn of the Dawn Horse). I will use Cixous’ seminal work, "The Laugh of the Medusa," to expand on this idea and how Carrington developed that language, constituted of her own personal symbols, which is on full display in her self-portrait.

- Description/Abstract:
- As I have previously shown, Alexandre Brongniart established a coherent science of ceramics. By the mid-nineteenth century, Brongniart had popularised the term "la céramique" as a widely-applicable name for the field of pottery and porcelain making, and other related arts. In the Twentieth Century, ceramic manufacturing became increasingly technical. The inclusive field of artisans and industrialists that Brongniart had once envisioned was fracturing. Voices called for the separation of pottery making from experimental, industrial ceramics and the meaning of the term “ceramics” was hotly debated. Numerous etymologies were traced, but, as the predominant language of science transferred from French to English, none of the twentieth-century authors recognized Brongniart’s key role in the invention of the term. Critically, this language debate coincided with and reflected the global politics, nationalism, and warfare of the first half of the Twentieth Century.

- Description/Abstract:
- Taking on the task of ordering the sciences related to pottery and clay-based objects, natural historian and porcelainier Alexandre Brongniart sought a new way of describing the ancient practice. Early in his forty-seven-year career as director of the Sèvres Porcelain Manufactory, Brongniart developed a research center for the advanced study of pottery and porcelain making. Brongniart recognized that an inclusive and distinct term for the field was necessary, but it had to be introduced carefully, so that it was welcomed rather than rejected as presumptuous. Through close reading of Brongniart’s writings, as well as contemporary periodicals and the texts of other authors, the development of the word “ceramic” – originally introduced by Brongniart and his associates in French as “la céramique” – can be traced closely. I show that this was a deliberate, methodical, and years-long effort to create a durable, comprehensive term.

- Description/Abstract:
- The young boy in Francisco de Zurbarán’s (1598-1664) Saint Peter Nolasco Recovering the Image of the Virgin of El Puig (1630) has been suggested to be either Zurbarán’s son, Juan de Zurbarán (1620–1649), or the son of James I of Aragon, Alfonso of Castile (1229–1260). Despite visual dominance, most scholars do not address the boy, and those who do offer conflicting identifications. This paper bridges the gap between these varying opinions, and concretely identifies the most formally important figure in this commission that defined Zurbarán’s career. The argument is built on the writings of Zurbarán scholar Martin S. Soria, as well as a comparison to Zurbarán’s body of work at large, primarily his tendency to create from life, and his suspected self-portrait, The Crucified Christ with a Painter (1650). I conclude that the child in the piece is likely a culmination of Juan and Alfonso and explore the implication of Zurbarán depicting his child in the noble and pious role of James the Conqueror’s son, paying witness to the rediscovery of the Virgin of El Puig. The combined figure of Juan and Alfonso gains significance through an exploration of historical context surrounding the legend of the Virgin of El Puig and its key figures. By drawing parallels between 17th-century Spanish colonialism contemporary to Zurbarán’s time and 13th-century Reconquista depicted in the painting, Zurbarán uses this composite figure to assert a vision of his lineage as triumphant and divinely favoured. Ultimately, this paper continues and expands upon Soria’s writings on the subject, and places Zurbarán within a Baroque tradition of artists, such as Velázquez, who used painting to assert their profession as divinely-inspired, nobel, and distinct from craftsmen.
