- Although the crustacean heart is modulated by a large number of peptides and amines, few of these molecules have been localized to the cardiac ganglion itself; most appear to reach the cardiac ganglion only by hormonal routes. Immunohistochemistry in the American lobster Homarus americanus indicates that pyrokinins are present not only in neuroendocrine organs ( pericardial organ and sinus gland), but also in the cardiac ganglion itself, where pyrokinin-positive terminals were found in the pacemaker cell region, as well as surrounding the motor neurons. Surprisingly, the single pyrokinin peptide identified from H. americanus, FSPRLamide, which consists solely of the conserved FXPRLamide residues that characterize pyrokinins, did not alter the activity of the cardiac neuromuscular system. However, a pyrokinin from the shrimp Litopenaeus vannamei [ADFAFNPRLamide, also known as Penaeus vannamei pyrokinin 2 (PevPK2)] increased both the frequency and amplitude of heart contractions when perfused through the isolated whole heart. None of the other crustacean pyrokinins tested (another from L. vannamei and two from the crab Cancer borealis) had any effect on the lobster heart. Similarly, altering the PevPK2 sequence either by truncation or by the substitution of single amino acids resulted in much lower or no activity in all cases; only the conservative substitution of serine for alanine at position 1 resulted in any activity on the heart. Thus, in contrast to other systems (cockroach and crab) in which all tested pyrokinins elicit similar bioactivities, activation of the pyrokinin receptor in the lobster heart appears to be highly isoform specific.

- Peptides are the largest and most diverse class of molecules used for neurochemical communication, playing key roles in the control of essentially all aspects of physiology and behavior. The American lobster, Homarus americanus, is a crustacean of commercial and biomedical importance; lobster growth and reproduction are under neuropeptidergic control, and portions of the lobster nervous system serve as models for understanding the general principles underlying rhythmic motor behavior (including peptidergic neuromodulation). While a number of neuropeptides have been identified from H. americanus, and the effects of some have been investigated at the cellular/systems levels, little is currently known about the molecular components of neuropeptidergic signaling in the lobster. Here, a H. americanus neural transcriptome was generated and mined for sequences encoding putative peptide precursors and receptors; 35 precursor- and 41 receptor-encoding transcripts were identified. We predicted 194 distinct neuropeptides from the deduced precursor proteins, including members of the adipokinetic hormone-corazonin-like peptide, allatostatin A, allatostatin C, bursicon, CCHamide, corazonin, crustacean cardioactive peptide, crustacean hyperglycemic hormone (CHH), CHH precursor-related peptide, diuretic hormone 31, diuretic hormone 44, eclosion hormone, FLRFamide, GSEFLamide, insulin-like peptide, intocin, leucokinin, myosuppressin, neuroparsin, neuropeptide F, orcokinin, pigment dispersing hormone, proctolin, pyrokinin, SIFamide, sulfakinin and tachykinin-related peptide families. While some of the predicted peptides are known H. americanus isoforms, most are novel identifications, more than doubling the extant lobster neuropeptidome. The deduced receptor proteins are the first descriptions of H. americanus neuropeptide receptors, and include ones for most of the peptide groups mentioned earlier, as well as those for ecdysistriggering hormone, red pigment concentrating hormone and short neuropeptide F. Multiple receptors were identified for most peptide families. These data represent the most complete description of the molecular underpinnings of peptidergic signaling in H. americanus, and will serve as a foundation for future gene-based studies of neuropeptidergic control in the lobster.

- In 2019, Korean American writer Cathy Park Hong published her memoir Minor Feelings: An Asian American Reckoning in the midst of a turning point in Asian American politics. Hong describes minor feelings as “emotions that are negative, dysphoric, and therefore untelegenic, built from the sediments of everyday racial experience and the irritant of having one’s perception of reality constantly questioned or dismissed.” Used as a concept to summate the Asian American experience in white America as living in a country where one’s reality is constantly questioned and made invisible, minor feelings forges an affective framework to study minoritized, diasporic literature. My project enriches Hong’s “minor feelings” by studying Korean American literature through a transnational and multimedia lens, considering how Korea’s colonial history and nation-building play roles in emoting Korean American self-realities. I structurally model my project after Sianne Ngai’s Ugly Feelings, split into four chapters, each focusing on one affect: shame, anger, han, and love. My project follows and documents the contemporary shifts occurring in Korean Americana, in how they perceive collective racial and diasporic identity, the intersectionality of layered identities, and the younger generations’ call for coalition. Since Korean American affects often are studied as an afterthought to Korean affects, my project retains a focus on the Korean American experience, recentering members of a diaspora whose globalizing homeland’s triumphs may eclipse their minor, invisible realities in America.

- ¿Cómo es que se puede escapar verdaderamente de la opresión patriarcal? Esta investigación aborda a través de un análisis de la literatura de escritoras del Cono Sur el asunto complicado de la liberación bajo un sistema en constante mutación. En el primer capítulo, a partir de aportes teóricos de Freud, Josefina Ludmer y Homi Bhabha entre otros, analizo cuentos de Jorge Luis Borges, Silvina Ocampo, y Clarice Lispector cuyas protagonistas intentan resistir su condición de víctima con diversos grados de éxito. En el capítulo que sigue, exploro una tendencia reciente en la literatura de escritoras del Cono Sur que incorpora elementos del horror y lo gótico para desestabilizar una cosmovisión humanista y patriarcal. Incorporando la teoría de Gabriel Giorgi, Rosi Braidotti, y Julieta Yelin, investigo los efectos que los animales, los cuerpos, y la materia tienen en la expansión de la agencia feminista y discuto si ofrecen o no nuevas e inesperadas posibilidades para resistir el sistema.

- The theory of functional approximation has numerous applications in sciences and industry. This thesis focuses on the possible approaches to approximate a continuous function on a compact subset of R2 using a variety of constructions. The results are presented from the following four general topics: polynomials, Fourier series, wavelets, and neural networks. Approximation with polynomials on subsets of R leads to the discussion of the Stone-Weierstrass theorem. Convergence of Fourier series is characterized on the unit circle. Wavelets are introduced following the Fourier transform, and their construction as well as ability to approximate functions in L2(R) is discussed. At the end, the universal approximation theorem for artificial neural networks is presented, and the function representation and approximation with single- and multilayer neural networks on R2 is constructed.

- This study provides the first analysis of the politics and ethics behind carbon taxation in South Africa and Mexico. Using the preexisting scholarly frameworks of climate change policy, tax policy, and Robert Putnam’s two level games, I determine that in both cases, international pressures from multilateral negotiations and international development funding sources initiated the carbon tax policymaking process within the environment and treasury ministries of both countries. Once environment ministry bureaucrats initiated the carbon tax a lack of politicization of climate change (both countries) and an additional gain of raising revenue (Mexico) allowed the taxes to become law. I then turn to the laws themselves, analyzing their implications for climate justice. In both cases, the government did not adopt any proposals made interest groups representing environmental concerns and poverty groups, and instead shaped the bills so as to tailor to the interests of heavy manufacturing. This policy decision had the main effect of weakening the climate change mitigation impact of the carbon tax, and exacerbating issues of regressivity by not recycling revenues towards projects aimed at poverty reductions. I conclude this paper with an analysis of the ethics of such a carbon tax in developing countries. The carbon taxes, as they currently exist, sacrifice the rights and needs of the present poor for those of the future generation while an ideal policy that addresses poverty betters the condition of both groups. In order to ensure climate justice and for all groups and prevent political backlash, policy makers in middle-income countries must make carbon reduction policies with the unique challenges of poverty and climate change mitigation in mind.

- This thesis investigates three predominantly Jewish housing cooperatives that emerged in the Bronx in the late 1920s. The Amalgamated Housing Cooperative, the United Workers Cooperative Colony (the “Coops”), and the Sholem Aleichem Houses offered garment workers utopian retreats from the drudgery of Lower East Side tenements where Jewish immigrants arrived in droves between 1890-1920. With each cooperative housing a distinct faction of the Jewish Left––from socialists to communists to Yiddish nationalists––the Bronx housing cooperatives, more than experiments in communal living, were the site of a highly contested battle over competing Jewish cultural and political worldviews across the 1930s and 1940s. Transcending the era that is typically considered the movement’s “peak” in the 1910s, this thesis demonstrates that the era of the Bronx cooperatives must be central to any study of the Jewish labor movement by revealing the ways radical Jews attempted to maintain and negotiate their various worldviews against the backdrop of the threats posed by the capitalist housing market, assimilation, and sectarian struggles. I reconsider the disproportionate attention the “success story” of the Amalgamated Cooperative has received, situating its politics as but one of many responses to the contradictions embedded in the housing cooperative model. Finally, I analyze the role of nostalgia present across resident recollections of the cooperatives and situate it in the contexts of 1970s neoliberal urban reform and suburbanization, while considering the discursive power of this emotion to obscure the persistent legacy of anti-black racism entangled in the cooperative housing movement despite its progressive reputation.

- In the decades following World War II, mass suburbanization remade the American landscape. While suburbs accounted for 83% of the nation’s growth between 1950 and 1970, cities bled their populations and natural resources dwindled. Treating the postwar era as a critical juncture, this thesis examines the political history of twentieth-century state land use policy to illuminate how competing interests have shaped policy outcomes across the United States. Specifically, the paper seeks to explain the passage of statewide growth management and smart growth programs. After providing a history of American suburbanization, the paper considers an emergent challenge to the postwar growth paradigm as manifested through resistance to urban renewal, open space loss, and diverse anti-freeway coalitions that combined actors from each movement. Thereafter, I detail the development of statewide growth management and smart growth programs before employing a set of case studies to discern causal factors associated with the success or failure of such legislation. Testing the theory that broad-based coalitions were essential to the passage of state growth management legislation, I perform a controlled comparison of two pairs of states, Maryland and Virginia and Oregon and Washington, employing additional within-case analysis for Washington. In so doing, I find evidence that diverse coalitions—from environmentalists and housing advocates to farmers and historic preservationists—were essential to the passage of state growth management programs. I conclude by considering the implications of these findings and the relevance of state land use policy to contemporary issues such as affordable housing and climate change.

- This work builds up the theory surrounding a recent result of Erlandsson, Leininger, and Sadanand: the Current Support Theorem. This theorem states precisely when a hyperbolic cone metric on a surface is determined by the support of its Liouville current. To provide background for this theorem, we will cover hyperbolic geometry and hyperbolic surfaces more generally, cone surfaces, covering spaces of surfaces, the notion of an orbifold, and geodesic currents. A corollary to this theorem found in the original paper is discussed which asserts that a surface with more than $32(g-1)$ cone points must be rigid. We extend this result to the case that there are more than $3(g-1)$ cone points. An infinite family of cone surfaces which are not rigid and which have precisely $3(g-1)$ cone points is also provided, hence demonstrating tightness.

- Increasingly, David Foster Wallace is becoming a cult figure among literary enthusiasts. His novels, essays, and short stories are all known for their poignant critiques of modern culture. Since his 2008 suicide, Wallace’s name has come to represent a way of thinking that rejects – and perhaps transcends – the hegemonic power of late capitalism. Wallace had a problem with pleasure. His writing often seemed to deflate or deconstruct what many people enjoy. For him, so much was “supposedly fun.” To understand Wallace’s relationship with pleasure, we must see how pleasure incorporates aesthetics and consumption. Wallace takes issue with the pleasure that comes from the aesthetics of cultural commodities. Irony produces pleasure, which turns culture into a desirable commodity. In my first chapter, I argue that Wallace’s essays challenge aesthetic pleasure by deconstructing self-reflexive irony. In his descriptions of consumer culture, Wallace evokes the feeling of disgust to undo the aesthetic pleasure of consumption. In my second chapter, I move to Infinite Jest to show how Wallace engages with irony while using it to exceed aesthetic pleasure. Infinite Jest challenges the hierarchy of aesthetics and suggests that deformity and waste can be beautiful and important. Infinite Jest demonstrates that, by trusting others instead of pursuing aesthetic ideals, people can build communities that are more honest and fulfilling than the pleasure of consumption.

- In this oral history, Ken Carpenter (Class of 1958), Deborah Carpenter Jenson (Class of 1983), and Jim Jenson (Class of 1982) reflect on their respective experiences at Bowdoin. Ken speaks of his background as an “orphan” (his father had died and his mother could not afford to raise him) attending Girard College for Boys, his transition to Bowdoin life as a first-generation student, and his involvement with the Delta Sigma fraternity. He also explores how the research skills that he gained at Bowdoin influenced his career as a cataloger, librarian, and author. Ken and his daughter, Deborah, go on to explain that, during his time at Bowdoin, Ken met his future wife, Mary Carpenter, at a boarding house in Brunswick run by Mary’s mother, Elizabeth Wilson. They later explain that Mary Carpenter had also lost her father and that Mary’s subsequent career in academia influenced Deborah’s career path. Deborah also recounts the factors that affected her decision to attend Bowdoin, as well as a hazing story from her early days at Delta Kappa Epsilon. Jim tells of his decision to enroll at the College, his transition from California to Maine, and his experience in the Theta Delta Chi fraternity. The three also discuss their thoughts on Bowdoin’s decision to eliminate fraternities.

- The Bondi solution, which describes the radial inflow of a gas onto a non-rotating black hole, provides a powerful test for numerical relativistic codes. However, this solution is typically derived in Schwarzschild coordinates, which are not well suited for dynamical spacetime evolutions. Instead, many current numerical relativistic codes adopt moving-puncture coordinates, which render black holes in trumpet geometries. Here we transform the Bondi solution into two different trumpet coordinate systems, both of which result in regular expressions for the fluid flow extending into the black hole interior. We also evolve these solutions numerically and demonstrate their usefulness for testing and calibrating numerical codes.

- Although traditional stage theories (e.g., Piaget, 1965) postulate that preschool age children are guided entirely by punishment avoidance and absolute deference to authority, more recent research suggests that their concepts of adult authority are complex and vary based on social cognitive domain and the content of the commands (e.g., Tisak, 1986). Also, although past studies have shown that the majority of children will reject adult authority in certain contexts, much individual variation between children has been observed (e.g., Laupa, 1994). The current study expanded upon past research by exposing children to multiple typical and atypical commands across domains, while also testing for individual differences based on two forms of parental authoritarianism. Results showed that children as young as four reject commands that go against established moral or conventional norms, and sometimes reject commands in the personal domain. This pattern grew stronger with age. High right-wing authoritarianism was a significant predictor of more authoritarian parenting style, and also predicted lower child support for authority in typical conventional scenarios.

Biographial Note
Harold M. Ickes was born on September 4, 1939, in Baltimore, Maryland, to Harold L. Ickes and Jane Dahlman. His father served as Franklin D. Roosevelt’s secretary of the interior. He attended high school at the Sidwell Friends School in Washington, D.C., was graduated from Stanford University in 1964 with a degree in economics, and earned his law degree from Columbia Law School in 1967. He was a civil rights activist during his student years in the ‘60s, spending the summers of 1964 and 1965 registering African American voters in Louisiana and Mississippi. In 1966, he became involved in the Vietnam anti-war movement. He later practiced labor law, joining the law firm Meyer, Suozzi, English & Klein in New York in 1977. He served as White House deputy chief of staff under Leon Panetta for three years during the Clinton administration; he was substantially involved in the Clinton administration’s push for health care reform. He has worked on several presidential campaigns, including those of Eugene McCarthy, George McGovern, Ted Kennedy, and Bill Clinton; for President Clinton’s campaign he was the New York State campaign chair. He also worked on Hillary Clinton’s Senate campaign in New York and later as the assistant to the campaign manager for her presidential primary bid in 2008. At the time of this interview, he was a registered lobbyist with the Ickes and Enright Group, a member of the Democratic National Committee Rules and Bylaws Committee, and president of Catalist, a progressive voter file organization.
Summary
Interview includes discussion of: Muskie presidential campaign 1972 and Ickes’ first encounter with Mitchell; being assigned to the health care brief and Whitewater damage control; why health care reform drafted by the Clinton administration failed to pass; Senator Mitchell’s attempt to get the health care legislation through; the White House’s relationship with key members of the Senate and House; the errors committed by the White House in not getting the input of Congress; the view the White House took of Mitchell and the belief that if he could not get the legislation passed, then no one could; Senator Moynihan’s role as chair of the Finance Committee; the Republicans’ effective strategy and how that differs from typical Democratic strategy through repetition and better focus; and Ickes’ impressions of Senator Mitchell.
