Flawed Feminism: An Exploration Of Femininity In Contemporary Domestic Noir, Tyler Miller

All Student Theses and Dissertations

Crime fiction is a genre whose female characters are often misunderstood, weak, powerless victims. Domestic noir, a subgenre of crime fiction, does the opposite. Authors of domestic noir fiction dig into the female experiences, seeking to understand and write women characters who represent feminism and femininity despite any shortcomings they have. In Big Little Lies by Liane Moriarty, I argue that reading this novel through the Critical Feminist Theory changes the interpretation of the female experience. Instead of reading the book for entertainment, digging into the larger scale issues in this book sheds light on the women’s experiences. Gone Girl …

Autodocking Studies Of Oxygenated Fullerenes As Inhibitors Of The Hiv Protease, Michael Kaminski

All Student Theses and Dissertations

In a previous study, several oxygenated fullerene compounds were produced by ozonation of C60 (Buckminsterfullerene) and were identified by elemental analysis and by SALI (surface analysis by laser ionization). Some of these compounds, especially a batch, SK-5, a mixture of C60O1-8, were shown to inhibit activities of HIV-Protease with IC50 (concentration for 50% inhibition) of 1 mg/mol in the in-vitro studies. The oxygenated fullerenes were shown to have epoxide, ketones, and hydroxyl functionalities. As expected, C60 interacted with ozone with alkene functionality and not as an aromatic compound. It was postulated that C60O had epoxide functionality, as a product of …

Advice, Suggestions, Recommendations, Clara E. Hill, Sarah Knox, Changming Duan

College of Education Faculty Research and Publications

Psychotherapist advice, suggestions, and recommendations (ASR) occur in many psychotherapy sessions and most treatment approaches. This chapter defines ASR, provides clinical examples, and reviews the research evidence for the immediate in-session, immediate delayed, and intermediate effects of ASR, as well as for the moderators of these effects in individual psychotherapy. In seven studies with 327 clients and 131 therapists, evidence of neutral immediate in-session outcomes (e.g., client experiencing levels), neutral immediate delayed outcomes (e.g., client-rated helpfulness during post-session videotape reviews), and positive intermediate outcomes (e.g., implementation of recommendations as rated in subsequent sessions) was found for ASR. These differences may …

Cultivating A Conscious Cohort: Sisterhood As A Site Of Institutional Change, Alexis Morgan Young, Mary (Mj) Johnson, Courtney A. Douglass, Blake O'Neal Turner

College of Education Faculty Research and Publications

This chapter discusses the implicit and explicit strategies the authors, four Black women graduate students, use to mentor each other. They use an iterative storytelling process, guided by a framework uncovered from data collected through Sista Circle Methodology, to discuss how their cohort itself is a conscious being with a mind, heart, body, and soul; that contributes to political and social change at our historically white institution. Their implications are for both graduate students and stakeholders in institutions of higher education – including faculty, staff, and administrators.

Synthesizing Energy Transitions, Danielle Stokes, Nadia Ahmad, Uma Outka, Hannah Wiseman

Law Faculty Publications

This Article assesses the growing and cross-disciplinary literature on energy transitions to explore how it can guide law and policy reforms for the energy sector. The modern conception of energy transition centers primarily on clean energy—a shift away from fossil energy dependence. It also, however, incorporates equity as a core principle, as an increasing emphasis on energy justice and just transition seeks to create guiding norms for the energy sector’s current state of change. The concept of energy transition is critical for describing and giving meaning to a fundamental societal shift at the local, regional, national, and global scales, aligned …

More Than An Icon: Taking Shirley Chisholm At Her Word, Marissa Jackson Sow

Law Faculty Publications

Shirley Anita St. Hill Chisholm is an American hero, one whose legacy and likeness have achieved iconic status within popular political culture, particularly as women have increasingly sought elected office. In 2019 in her home state of New York, Governor Andrew Cuomo created a state park in her honor. Several months earlier, New York City mayor Bill de Blasio’s administration had announced the creation of a monument in Chisholm’s honor in Brooklyn’s Prospect Park. Both sites incorporate and rely on both the visual depictions of Chisholm that have become political iconography—the Congresswoman’s dark brown face and glasses centered by a …

The Haunting Of Wealth Law, Allison Anna Tait

Law Faculty Publications

Wealth law is full of ghosts, ghosts everywhere all at once. As a form of both preservation and disruption, a form of continuance as well as a form of interruption, ghosts are reminders of the past in its multiple forms. But they are also figures that prompt consideration of the present as well as speculation about the future. Jacques Derrida, who suggested the idea of “hauntology,” posited haunting and the ghostly as being “time out of joint,” a reference to Hamlet’s confused cry upon seeing his father’s ghost that Derrida analyzes extensively. In this sense, ghosts are akin to inheritance, …

Conceptualizing The Construct Of Ocean Identity, Miriah R. Kelly, Jo-Marie Kasinak, Emma Mckinley, Caitlin Mclaughlin, Jamie M.P. Vaudrey, Jennifer Mattei

Biology Faculty Publications

The construct of ocean identity provides a valuable lens that can unpack the multiple dimensions of human connections with ocean spaces, and crucially places importance on the integration of cognitive, affective, and behavioral components. The construct of ocean identity is applicable in academic and professional contexts, and is largely unexplored from both qualitative and quantitative research perspectives. This comment article presents a revised definition of ocean identity and posits a useful conceptual framework based on a robust analysis of literature to unveil the multiple dimensions that may explain an individuals’ ocean identity. Here we identify a series of attributes that …

Evidence For A Single, Ancient Origin Of A Genus-Wide Alternative Life History Strategy, Kalle Tunström, Alyssa Woronik, Joseph J. Hanly, Pasi Rastas, Anton Chichvarkhin, Andrew D. Warren, Akito Kawahara, Sean D. Schoville, Vincent Ficarrotta, Adam H. Porter, Ward B. Watt, Arnaud Martin, Christopher W. Wheat

Biology Faculty Publications

Understanding the evolutionary origins and factors maintaining alternative life history strategies (ALHS) within species is a major goal of evolutionary research. While alternative alleles causing discrete ALHS are expected to purge or fix over time, one-third of the ~90 species of Colias butterflies are polymorphic for a female-limited ALHS called Alba. Whether Alba arose once, evolved in parallel, or has been exchanged among taxa is currently unknown. Using comparative genome-wide association study (GWAS) and population genomic analyses, we placed the genetic basis of Alba in time-calibrated phylogenomic framework, revealing that Alba evolved once near the base of the genus and …

Biden, Bennet, And Bipartisan Federal Judicial Selection, Carl Tobias

Law Faculty Publications

"The U.S. Constitution plainly assigns to the Senate the profound duties of rendering critical advice and consent related to all specific federal judicial nominees whom the President selects. The dynamic roles of senators who directly represent jurisdictions where vacant posts materialize have perennially been crucial to appropriately discharging these essential responsibilities. Senators identify excellent candidates—individuals who possess diversity in terms of ethnicity, gender, sexual orientation, independence, experience, and ideology, as well as the character and measured judicial temperament to be exceptional jurists—assemble complete applications, comprehensively review the prospects, and interview choices whom the senators duly recommend to the President. After …

A Wrong Turn With The Rights Of Nature Movement, Noah M. Sachs

Law Faculty Publications

Environmentalists have long dreamed of granting enforceable legal rights to nature, and their vision has recently become reality. Governments in the United States and abroad are enacting Rights of Nature laws, and many scholars have championed this burgeoning movement as one of the best hopes for preserving the environment.

Legal rights for nature seem visionary, but policymakers and scholars are overlooking considerable problems with this approach. This Article spotlights these problems, including the vague and incoherent content of nature’s rights, the difficulty of defining the boundaries of natural entities, the absence of limiting principles for the rights, and the legislation’s …

The Business Of Securities Class Action Lawyering, Jessica M. Erickson, Stephen J. Choi, Adam C. Pritchard

Law Faculty Publications

Plaintiffs’ lawyers in the United States play a key role in combating corporate fraud. Shareholders who lose money as a result of fraud can file securities class actions to recover their losses, but most shareholders do not have enough money at stake to justify overseeing the cases filed on their behalf. As a result, plaintiffs’ lawyers control these cases, deciding which cases to file and how to litigate them. Recognizing the agency costs inherent in this model, the legal system relies on lead plaintiffs and judges to monitor these lawyers and protect the best interests of absent class members. Yet …

Evidence Rules For Decarceration, Erin Collins

Law Faculty Publications

Two observations about the operation of the criminal legal system are so widely accepted that they are seem undeniable: First, it is a system of pleas, not trials. Second, the system is too punitive and must be reformed. One could easily think, therefore, that the Rules of Evidence, which apply intentionally and explicitly only to the adjudicatory phase of criminal procedure, have nothing to do with the solution. And legal scholarship focusing on decarceration largely reflects this assumption: while many have explored reforms that target front end system actors and processes that lead people into the system (e.g. police, prosecutors, …

Fighting For Whiteness In Ukraine, Marissa Jackson Sow

Law Faculty Publications

Teri McMurtry-Chubb’s Race Unequals: Overseer Contracts, White Masculinities, and the Formation of Managerial Identity in the Plantation Economy offers groundbreaking insights into the gendered economic hierarchies internal to the body politic of whiteness through its examination of the limitations that plantation overseers’ contracts in the American Deep South placed on their ability to exercise the proprietorship and contracting authority prerequisite to white identity. This Essay uses the Ukrainian campaign to be recognized as a liberal white nation, and formally become a member of the West, as a contemporary case study of how whiteness remains hegemonized and subject to the ability …

Confirm Rachel Bloomekatz To The Sixth Circuit, Carl Tobias

Law Faculty Publications

Now that the United States Senate is convening after the July Fourth holiday, the upper chamber must promptly appoint Rachel Bloomekatz to the U.S. Court of Appeals for the Sixth Circuit. The nominee, whom President Joe Biden selected in May 2022, provides remarkable experiential, gender, and ideological expertise that she deftly realized in litigating high-profile gun control, environmental, and other significant cases in federal appellate courts and district courts. Over fifteen years, the nominee has reached law’s pantheon across a broad spectrum from extremely prestigious clerkships with Justice Stephen Breyer and particularly distinguished federal court and state court jurists to …
