- This thesis explores the emergence of international courts as venues for climate activists, and how climate litigation connects climate change-related damages to human rights law to broaden human rights norms related to the environment. Through three case studies of international climate cases, this project evaluates the effectiveness of international climate litigation through direct effectiveness, indirect effectiveness, and normative effectiveness. It argues that international climate cases are involved in the work of larger transnational advocacy networks who engage with issue framing that presents their causes to both a legal and a public audience. Framing is an ongoing, contested process that both activists and respondent states engage with, but the processes of norm development and socialization it prompts may ultimately work to advance the idea of climate and environment-related rights.

- This project explores novel approaches to image segmentation using U-Net, leveraging superpixels to enhance accuracy. The first part investigates augmenting standard image inputs by encoding and integrating superpixel information, including an extension that reintroduces this information throughout the encoder. While results show that these methods can offer consistent improvements over the baseline, the gains are modest and suggest room for further optimization. The second part introduces a hybrid data structure, the Superpixel-Integrated Grid (SIGrid), which embeds superpixel boundary, shape, and color descriptors into a regular n × n grid. SIGrid enables more efficient training on smaller architectures while achieving noticeably higher segmentation accuracy, highlighting its potential as a lightweight and effective input representation.

- Large impoundment dams have well-documented impacts on hydrologic and geomorphicfunction. Numerous tools and metrics have been developed over time to characterize theseimpacts, but they remain disparate, are often applied in a small number of studies, and rarelyapplied in concert with each other. Utilizing the open-source programming language R, Iassemble a suite of metrics known as DAMS – the Dam Analysis and Metrics Suite – thatcombines several pre-existing metrics for characterizing dam impacts into one script. Thesemetrics include the Indicators of Hydrologic Alteration to characterize hydrologic change; themean streambed elevation to characterize vertical change in the river; and sediment mass balanceand flood magnitude reduction. By combining these schemas, DAMS provides a flexible andcomprehensive way to characterize the impact of dams on hydrology and geomorphology.I apply DAMS to two dams in diverse geographic settings: the Buford Dam on theChattahoochee River in Georgia and the Harris Station Dam on the Kennebec River in Maine.Both are hydroelectric dams with long stream gage records before and after dam construction. Ifound that the Buford Dam has caused a decrease in high flows in the Chattahoochee River aswell as a change in the seasonality of flows. I found that the Kennebec River has seen anincrease in high and peak flow volume after the construction of the Harris Station Dam, but thisincrease is less than comparable unimpounded rivers. The geomorphic data the ChattahoocheeRiver is fairly limited and cannot be access for the Kennebec River at all, meaning that DAMSwas unable to tell a complete story about how these rivers changed due to impoundment,highlighting the need for increased monitoring on all of the United States’ rivers.

- This study examines the institutional and emotional dynamics within a multidisciplinary team that consists of law enforcement (LE), the Department of Health and Human Services (DHHS), and sexual assault support staff who handle child sexual abuse cases. Employees interpret trauma differently depending on the organizational framework they operate within. The way professionals construct trauma shapes caregivers’ outlook on the process and ultimately affects how they care for their children. While LE and DHHS prioritize legal compliance, the sexual assault support staff advocate for trauma-informed care. Using semi-structured interviews with seven sexual assault support staff members who identified as women or non-binary, this research explores the way they manage the gendered burden of emotional labor, the systemic undervaluation of trauma-informed practices, and the emotional challenges caregivers face in supporting child survivors. Findings show the friction between the multidisciplinary team, emphasizing the need for integrated trauma-informed training and community-based support systems for caregivers.

- We introduce a new time-independent family of analytical coordinate systems for the Kerr spacetime representing rotating black holes. We also propose a (2+1)+1 formalism for the characterization of trumpet geometries. Applying this formalism to our new family of coordinate systems we identify, for the first time, analytical and stationary trumpet slices for general rotating black holes, even for charged black holes in the presence of a cosmological constant. We present results for metric functions in this slicing and analyze the geometry of the rotating trumpet surface.

- In their September 2020 paper [Appl. Opt.59, 7585 (2020)], Purschke et al . report UV-C transmittance measurements of N95 filtering facepiece respirators (FFRs), including the 3M 1860, which is one of the most widely used FFRs.We have also measured the transmittance of this FFRin our two separate laboratories with multiple FFR samples, and we have obtained transmittance values similar to one another, but very different from what Purschke et al . reported for two of the four FFR layers.

- We have measured the B0B»0 mixing probability, d, using a sample of 965 000 BB» pairs from (4S) decays. Counting dilepton events, we find d=0.1570.0160.018-0.021+0.028. Using tagged B0 events, we find d=0.1490.0230.0190.010. The first (second) error is statistical (systematic). The third error reflects a 15% uncertainty in the assumption, made in both cases, that charged and neutral B pairs contribute equally to dilepton events. We also obtain a limit on the CP impurity in the Bd0 system, Re(B0)<0.045 at 90% C.L. © 1993 The American Physical Society.

- We have studied hadronic decays of B mesons. We report measurements of exclusive branching ratios of several charm decay modes of B mesons to final states with a D or D* and one to three charged pions or a charged and to final states with a or , a kaon, and up to two charged pions. We have also measured inclusive branching ratios for B decays to D and D* and the spectra of these particles in B decays. The total charm content in B decay is found to be (10112)%. The branching ratios and spectra are compared to form-factor models. We extract the parameters a1 and a2 of the model of Bauer, Stech, and Wirbel and the DS decay constant. The masses of the B0 and B- mesons are measured. The mass difference between B0 and B- is found to be -0.40.60.5 MeV/c2. © 1992 The American Physical Society.

- The tau lepton electron branching fraction has been measured with the CLEO II detector at the Cornell Electron Storage Ring as Be=0.17490.00140.0022, with the first error statistical and the second systematic. The measurement involves counting electron-positron annihilation events in which both taus decay to electrons, and normalizing to the number of tau-pair decays expected from the measured luminosity. Detected photons in these events constitute a definitive observation of tau decay radiation. © 1992 The American Physical Society.

- New measurements of the carbon and hydrogen isotopic ratios of methane (δ13 C of CH4 and δD of CH4) over the last millennium are presented from the WAIS Divide, Antarctica, ice core (WDC05A), showing significant changes that likely were the result of human influences prior to the industrial revolution (at least as early as the 16th century of the common era (CE)). The (δ13C of CH4 data corroborate the record from Law Dome, Antarctica, with high fidelity. The new δD of CH4 data set covaries with the (δ13C of CH4 record. Both (δ13C of CH4 and δD of CH4 were relatively stable and close to the present-day values from ∼to ∼CE. Both isotopic ratios decreased to minima around 1700 CE, remained low until the late 18th century, and then rose exponentially to present-day values. Our new δD of CH4 data provide an additional independent constraint for evaluating possible CH4 source histories. We searched a broad range of source scenarios using a simple box model to identify histories consistent with the constraints of the CH 4 concentration and isotope data from 990-1730 CE. Results typically show a decrease over time in the biomass-burning source (found in 85% of acceptable scenarios) and an increase in the agricultural source (found in 77% of acceptable scenarios), indicating preindustrial human influence on atmospheric methane as proposed in previous studies. © 2009 by the American Geophysical Union.

- We study the WZW, Chern-Simons, and 2d qYM theories with gauge group U(N). The U(N) WZW model is only well-defined for odd level K, and this model is shown to exhibit level-rank duality in a much simpler form than that for SU(N). The U(N) Chern-Simons theory on Seifert manifolds exhibits a similar duality, distinct from the level-rank duality of SU(N) Chern-Simons theory on S 3. When q ≤ e2πi/(N+K), the observables of the 2d U(N) qYM theory can be expressed as a sum over a finite subset of U(N) representations. When N and K are odd, the qYM theory exhibits N K duality, provided q ≤ e2πi/(N+K) and θ ≤ 0 mod 2π/(N + K). © SISSA 2007.

- We have measured the weak decay asymmetry parameters (αΛc) for two Λc+ decay modes. Our measurements are αΛc = -0.94-0.06-0.06+0.21+0.12 for the decay mode Λc+ → Λπ+ and αΛc = -0.45 ±0.31 ±0.06 for the decay mode Λc → Σ+ π0. By combining these measurements with the previously measured decay rates, we have extracted the parity-violating and parity-conserving amplitudes. These amplitudes are used to test models of nonleptonic charmed baryon decay. © 1995.

- The one-instanton contribution to the prepotential for N = 2 supersymmetric gauge theories with classical groups exhibits a universality of form. We extrapolate the observed regularity to SU (N) gauge theory with two antisymmetric hypermultiplets and Nf ≤ 3 hypermultiplets in the defining representation. Using methods developed for the instanton expansion of non-hyperelliptic curves, we construct an effective quartic Seiberg-Witten curve that generates this one-instanton prepotential. We then interpret this curve in terms of an M-theoretic picture involving NS 5-branes, D4-branes, D6-branes, and orientifold sixplanes, and show that for consistency, an infinite chain of 5-branes and orientifold sixplanes is required, corresponding to a curve of infinite order. © 1999 Elsevier Science B.V.

- We study the subleading-color (nonplanar) contributions to the four-gluon scattering amplitudes in = 4 supersymmetric SU(N) Yang-Mills theory. Using the formalisms of Catani and of Sterman and Tejeda-Yeomans, we develop explicit expressions for the infrared-divergent contributions of all the subleading-color L-loop amplitudes up to three loops, and make some conjectures for the IR behavior for arbitrary L. We also derive several intriguing relations between the subleading-color one- and two-loop four-gluon amplitudes and the four-graviton amplitudes of = 8 supergravity. The exact one- and two-loop = 8 supergravity amplitudes can be expressed in terms of the one- and two-loop N-independent = 4 SYM amplitudes respectively, but the natural generalization to higher loops fails, despite having a simple interpretation in terms of the 't Hooft picture. We also find that, at least through two loops, the subleading-color amplitudes of = 4 SYM theory have uniform transcendentality (as do the leading-color amplitudes). Moreover, the = 4 SYM Catani operators, which express the IR-divergent contributions of loop amplitudes in terms of lower-loop amplitudes, are also shown to have uniform transcendentality, and to be the maximum transcendentality piece of the QCD Catani operators. © SISSA 2008.

In addition to the D3-branes and an O7-plane, the background contains eight D7-branes, which give rise to matter in the fundamental representation of the gauge group.

- A measurement of the cross section for the combined two-photon production of charged pion and kaon pairs is performed using 1.2 fb-1 of data collected by the CLEO II detector at the Cornell Electron Storage Ring. The cross section is measured at invariant masses of the two-photon system between 1.5 and 5.0 GeV/c2, and at scattering angles more than 53° away from the γγ collision axis in the γγ center-of-mass frame. The large background of leptonic events is suppressed by utilizing the CsI calorimeter in conjunction with the muon chamber system. The reported cross section is compared with leading order QCD models as well as previous experiments. Although the functional dependence of the measured cross section disagrees with leading order QCD at small values of the two-photon invaraint mass, the data show qualitatively a transition to perturbative behavior at an invariant mass of approximately 2.5 GeV/c2. © 1994 The American Physical Society.

On June 29, 2012, five Wabanaki Chiefs and Maine’s Governor Paul LePage signed a mandate commencing the Maine Wabanaki-State Child Welfare Truth and Reconciliation Commission (TRC). Under the leadership of five appointed commissioners, the TRC was charged with examining Maine’s child welfare practices affecting Wabanaki people; the focus of the Commission was on "truth, healing, and change." Over the course of three years, the TRC collected statements from nearly 150 individuals and focus groups. The TRC published a final report on June 14, 2015, detailing key findings and recommendations for further action.
At the conclusion of its work, the TRC transferred its extensive archives to the Bowdoin College Library’s George J. Mitchell Department of Special Collections & Archives. The collection includes video, audio, and written statements, and other personal documents contributed by participants, founding documents, the final report, and administrative and research records. This website provides online access to all the unrestricted statements that are part of the collection. Researchers interested in consulting other components of the collection described in the online inventory may do so by visiting the George J. Mitchell Department of Special Collections & Archives.
