No Exception For Ultra Vires Discrimination, Rev. James Deboer

American University Journal of Gender, Social Policy & the Law

The Ministerial Exception (“the Exception”) is an affirmative defense that religious institutions may use to obtain dismissal of discrimination claims brought by current and former ministerial employees.The Exception rests on the seemingly straightforward premise that churches and other religious institutions must be free to select and remove their own ministers without interference from secular laws.  It applies with equal force to any kind of discrimination; extends to harassment and retaliation; and is not confined to forms of alleged discrimination motivated by religious belief.

The Supreme Court has only addressed the Exception twice. First, in 2012, through Hosanna-Tabor Evangelical Lutheran Church …

Why Dobbs Is No Roadmap For Deciding State Constitutional Abortion Issues, Daniel A. Small

American University Journal of Gender, Social Policy & the Law

In deciding that Fourteenth Amendment “liberty” does not protect a woman’s decision to end her pregnancy, Dobbs v. Jackson Women’s Health Organization sought to distinguish the precedent that Roe and Casey relied on to recognize an abortion right. The Dobbs majority claimed that this precedent did not support a right to abortion because, in its view, destroying a fetus is more immoral than the conduct at issue in those earlier cases. However, moral concerns about fetal destruction shed no light on the nature or characteristics of a woman’s liberty interest in an abortion decision. These concerns, therefore, cannot show whether …

What Is “The Nation’S History And Tradition?”: Using History To Redefine “Liberty” And Applying A New Deeply Rooted Test To Transgender Rights, Kaori Kawaguchi

American University Journal of Gender, Social Policy & the Law

INTRODUCTION: “In a Constitution for a free people, there can be no doubt that the meaning of ‘liberty’ must be broad indeed.” In Roe v. Wade, the Court considered a woman’s liberty right to decide whether to continue a pregnancy or have an abortion and recognized the constitutional validity of a liberty right to abortion as part of the right to privacy. In Roe, the Court concluded, “[o]nly personal rights that can be deemed ‘fundamental’ or ‘implicit in the concept of ordered liberty’ are included in the guarantee of a right of personal privacy.” Liberty should be “left to …

Nonviolent Felony Offenders And The Second Amendment: Reexamining Categorical Disarmament Laws In Light Of Bruen And Rahimi, Nikolay Belardi

American University Journal of Gender, Social Policy & the Law

INTRODUCTION: The Second Amendment ensures that “the right of the people to keep and bear Arms, shall not be infringed.” In a country with more civilian-owned firearms than people—and more gun dealers than McDonald’s, Burger King, Subway, and Wendy’s locations combined—it is no surprise that Americans pride themselves on their right to bear arms. However, a majority of the American population favors stricter gun laws and regulations, a position that seems sensible given that mass shootings are an all-too-familiar occurrence in the United States. The enshrinement of the right to bear arms in the Constitution limits the laws and regulations …

Twelve current or former students who experienced academic probation at some …

Why Is It Always The Boys?: Evaluating Disciplinary Issues Within The Classroom, Brian P. Lynch

West Chester University Graduate Theses, Dissertations, and Final Projects

This thesis explores the concept of discipline in the classroom and the overrepresentation of male students in disciplinary action.  American public schools are nearly equally represented with male and female students, yet disciplinary action is taken far more frequently toward male students.  Throughout the course of this paper, a history of disciplinary action in America is relayed.  Psychological and social factors are acknowledged to explain the differences of actions in the classroom between male and female students.

To best impact students in the classroom and relieve the overrepresentation of male disciplinary issues, a community program should take place throughout the …

What We're Not Allowed To Teach: The Epistemic Suppression Of The Null Curriculum In American Formal Education, Monica Zheng

West Chester University Graduate Theses, Dissertations, and Final Projects

This thesis explores the history and impact of the null curriculum, which Eisner (1994) defines as "what schools do not teach" (p. 97). The null curriculum often contradicts the messages that the dominant white-supremacist patriarchy has indoctrinated into the explicit curriculum into the curriculum that American formal education uses, especially with the advent of high-stakes standardized testing. In order to overthrow this capitalist system, teachers must feel safe teaching the null curriculum. This thesis makes the case that internal reform of the American formal education system is not enough to create this liberated learning experience, and an external, full …

Generation Z: Black Male Constructions Of Masculinity And Provider Roles In Heterosexual Marriages, Bentley Stafford Hylton

Antioch University Dissertations & Theses

This study explores how expectations associated with the male provider role identity impact the psychological well-being of Black American Generation Z (“Gen Z”) men. Using a qualitative design, approximately 20 participants were surveyed to examine how efforts to meet provider role expectations influence well-being, as well as how Gen Z Black men construct and define masculinity within contemporary sociocultural contexts. While prior research has examined Black masculinity, limited attention has been given to its intersection with provider role expectations, particularly among emerging adults. Historically, messages about masculinity and marital roles have been transmitted through community institutions, leadership, and cultural narratives; …

More Than Surviving: Brazilian Immigrants' Stories Of Growth And Wellbeing In The United States, Virginia Veronica Lemos

Antioch University Dissertations & Theses

Immigration in the United States is often conceptualized within clinical psychology through deficit-oriented frameworks that emphasize risk, trauma, and psychological distress. While this work is essential for documenting vulnerability and inequity, it offers limited guidance for understanding how immigrants sustain wellbeing and meaning amid ongoing sociopolitical and institutional constraints. Brazilian immigrants represent a large and growing population in the US whose experiences remain comparatively understudied, particularly from strengths-based and interpretive perspectives. To address this gap, this qualitative study explores how Brazilian immigrants make sense of immigration and wellbeing through the narratives they construct about their lives in the US. Grounded …
