description: The Rarita-Schwinger operator is the twisted Dirac operator restricted to 3/2-spinors. Rarita-Schwinger fields are solutions of this operator which are in addition divergence-free. This is an overdetermined problem and solutions are rare; it is even more unexpected for there to be large dimensional spaces of solutions. In this paper we prove the existence of a sequence of compact manifolds in any given dimension greater than or equal to 4 for which the dimension of the space of Rarita-Schwinger fields tends to infinity. These manifolds are either simply connected Kähler-Einstein spin with negative Einstein constant, or products of such spaces with flat tori. Moreover, we construct Calabi-Yau manifolds of even complex dimension with more linearly independent Rarita-Schwinger fields than flat tori of the same dimension.

description: In this paper, we characterize a mechanism for reducing pollution emissions in which countries, acting non-cooperatively, commit to match each others’ abatement levels and may subsequently engage in emissions quota trading. The analysis shows that the mechanism leads to efficient outcomes. The level of emissions is efficient, and if the matching abatements process includes a quota trading stage, the marginal benefits of emissions are also equalized across countries. Given the equilibrium matching rates, the initial allocation of emission quotas (before trading) reflects each country’s marginal valuation for lower pollution relative to its marginal benefit from emissions. These results hold for any number of countries, in an environment where countries have different abatement technologies and different benefits from emissions, and even if the emissions of countries are imperfect substitutes in each country’s damage function. In a dynamic two-period setting, the mechanism achieves both intra-temporal and inter-temporal efficiency. We extend the model by assuming that countries are voluntarily contributing to an international public good, in addition to undertaking pollution abatements, and find that the level of emissions may be efficient even without any matching abatement commitments, and the marginal benefits of emissions may be equalized across countries even without quota trading.
Healing resources and rebuilding lives: A missed opportunity in Bosnia and Herzegovina?
Creators: name: Lazarescu, Maria Ruxandra
Publisher: name: American University
Year: 2023

description: Stories of people who experienced violent conflict rarely make the big news but they are rich resources and guides for peacebuilding and development interventions. This qualitative study, through loosely structured interviews, explores sources of healing of Bosnian people who lived in Sarajevo at the time of the conflict and who now live in the US. An opportunity was missed to get the local population engaged in the process of transformation of the society. Providing targeted and tailored psychosocial support not only to the most affected groups but to the entire population, as well as close coordination and linkages between peacebuilding and development practitioners and organizations is likely to greatly improve outcomes of post-conflict reconstruction. Further research the impact of such coordination and efforts to heal, empower and engage the local population is necessary to reveal best practices and success stories and to convince donors of their importance.

description: Organic wheat production is generally profitable in the West, but farmers considering organic conversion or maintaining current organic fields face uncertainty due to significant price variations over time. The ability to predict price movements in this market is complicated by the limited availability of pricing data as well as missing observations. This study evaluates three methods to impute missing price observations. Additionally, we investigate short- and long-run relationships between organic and conventional wheat prices to understand whether conventional prices can help to predict organic wheat prices. Results indicate that conventional wheat prices influence organic prices, but only in the short run.

description: The paper examines the importance of including specialty and ethnic food stores in defining and identifying food deserts in a multi-ethnic suburban neighborhood. The paper uses an in-store food availability survey and GIS techniques to test the hypothesis that the availability of healthy and affordable food options will be considerably under-reported when not accounting for ethnic and specialty food stores in food desert analysis. Although a relatively large portion of the study area remains a food desert, ethnic and specialty food stores significantly offset the lack of supermarkets and grocery stores in providing healthy and affordable food options.

description: Measuring the properties of extragalactic magnetic fields through the effect of Faraday rotation provides a means to understand the origin and evolution of cosmic magnetism. Here we use data from the LOFAR Two-Metre Sky Survey (LoTSS) to calculate the Faraday rotation measure (RM) of close pairs of extragalactic radio sources. By considering the RM difference ($Δ$RM) between physical pairs (e.g. double-lobed radio galaxies) and non-physical pairs (i.e. close projected sources on the sky), we statistically isolate the contribution of extragalactic magnetic fields to $Δ$RM along the line of sight between non-physical pairs. From our analysis, we find no significant difference between the $Δ$RM distributions of the physical and non-physical pairs, limiting the excess Faraday rotation contribution to $< 1.9$ rad/m$^2$ ($\sim$$95\%$ confidence). We use this limit with a simple model of an inhomogeneous universe to place an upper limit of 4 nG on the cosmological co-moving magnetic field strength on Mpc scales. We also compare the RM data with a more realistic suite of cosmological MHD simulations, that explore different magnetogenesis scenarios. Both magnetization of the large scale structure by astrophysical processes such as galactic and AGN outflows, and simple primordial scenarios with seed magnetic field strengths $< 0.5$ nG cannot be rejected by the current data; while stronger primordial fields or models with dynamo amplification in filaments are disfavoured.

description: Krabbe disease (KD), also known as globoid cell leukodystrophy disease, is an autosomal recessive lysosomal storage genetic disorder, which is caused by the deficiecncy of galactocerebrosidase (GALC) coding gene (GALC). This sudy aimed to use an extensive computational pipelines in understanding the missense mutations in GALC. We retrieved 176 mutations from the public databases and subjected them to pathogenicity, stability, and conservation analysis. The PredictSNP, iStable, and ConSurf prediction tools predicted 45, 95, and 47 mutations to be deleterious, destabilizing, and highly conserved, respectively. The R396L and R396W were the most deleterious and destabilizing to GALC, therefore were prioritized for further analysis. Systematic validation on the impact of the R396L and R396W mutations to the chaperone alpha lobeline was performed using the molecular docking approach. The docking analysis revealed that the mutant R396W interacted with minimal binding affinity compared with both the R396L mutant and native GALC. Further, the repetitive molecular dynamics simulation analysis showed that the mutant R396W demonstrated less compactness and reduced number of intramolecular hydrogen bonds compared with the mutant R396L and native GALC. Overall, we observed higher structural and functional modifications in R396W positioned in the substrate-binding site. This was highly supported by the MMPBSA and DSSP analysis of the GROMACS. DSSP that showed the transformation of turns to bends, indicating a loss of stability due to the R396W mutation. This study is expected to server as a platform for prioritizing mutant proteins that could be a platform for both drug and target therapeutics

description: The target theory is the most classical hypothesis explaining radiation-induced cell death, the physical or biological nature of the "target" remains ambiguous. This study hypothesizes that the distribution of DNA double-strand breaks (DSBs) within the 3D genome is a pivotal factor affecting the probability of radiation-induced cell death. We propose that clustered DSBs in DNA segments with high interaction frequencies are more susceptible to leading to cell death than isolated DSBs. Topologically associating domains (TAD) can be regarded as the reference unit for evaluating the impact of DSB clustering in the 3D genome. To quantify this correlation between the DSB distribution in 3D genome and radiation-induced effect, we developed a simplified model considering the DSB distribution across TADs. Utilizing track-structure Monte Carlo codes to simulate the electron and carbon ion irradiation, we calculated the incidence of each case across a variety of radiation doses and LETs. Our simulation results indicate that DSBs in TADs with frequent interactions (case 3) are significantly more likely to induce cell death than clustered DSBs within a single TAD (case 2). Moreover, case 2 is significantly more likely to induce cell death than isolated DSBs (case 1). The curves of the incidence of case 2 and case 3 versus LETs have a similar shape to the radiation quality factor used in radiation protection. This indicates that these two cases are also associated with the stochastic effects induced by high LET irradiation. Our study underscores the significance of the 3D genome structure in the fundamental mechanisms of radiobiological effects. The hypothesis in our research offers novel perspectives on the mechanisms that regulate radiobiological effects. Moreover, it serves as a valuable reference for establishing mechanistic models that can predict cell survival under different doses and LETs.

Truth commissions in Africa: Learning over a decade

Year: 2023

description: This paper examines the learning processes of truth commissions and their institutional dynamics in order to trace how these human rights organizations learn and change as they carry out their mandates. Using qualitative methodology, the study investigates the role and influence of human rights norms while tracing the learning processes of truth commissions. The effect of truth commissions on international norms and law is also studied as part of the broader question of how these institutions acquire knowledge. Finally, the research findings are analyzed to determine whether realism, constructivism, or institutionalism best explains the observed phenomena. Two claims regarding truth commissions are made. The first claim is that the standardized organizational format of truth commissions affects how they learn, implement changes, and carry out their investigatory mandates. The second claim is that given their limited lifespan as organizations, truth commissions have developed institutional processes of acquiring knowledge that relies heavily and exclusively on previous commissions, international human rights NGOs, and U.N. human rights departments. This paper argues that this reliance on past practices and standardization leads to unintended consequences that sometime hamper the effective execution of truth commissions' mandates.

Data from a consumer survey conducted in Georgia was used to determine the potential domestic market for value-added goat meat products among foreign- and nativeborn Americans. About 56% of participants who had never tasted goat meat expressed willingness to taste if the grocery stores gave out goat meat samples. Current goat meat consumers were more willing to pay for locally grown, grass fed, and organic goat meat.

description: Quantum data locking is a quantum communication primitive that allows the use of a short secret key to encrypt a much longer message. It guarantees information-theoretical security against an adversary with limited quantum memory. Here we present a quantum data locking protocol that employs pseudo-random circuits consisting of Clifford gates only, which are much easier to implement fault tolerantly than universal gates. We show that information can be encrypted into $n$-qubit code words using order $n - H_\mathrm{min}(\mathsf{X})$ secret bits, where $H_\mathrm{min}(\mathsf{X})$ is the min-entropy of the plain text, and a min-entropy smaller than $n$ accounts for information leakage to the adversary. As an application, we discuss an efficient method for encrypting the output of a quantum computer.

description: When the Wheel Comes Off is a collection of short stories that explores the themes of intimacy in the relationships between lovers, spouses and friends. "So Turn Golden Rings" delves into the psyche of unfaithful husband when he is disturbed in the night by a noise downstairs. He finds himself wandering the house and his mind together. The title story takes place at an amusement park and deals with two friends, one now a third wheel. In "Sunday's Revelations" a young girl encounters her first brush with adult sexuality and the irrationality of the emotions of intimacy. These situations bring the tensions of relationships into focus and allows each story to explore how intimacy is gained and lost. The constant flux of intimacy is revealed as people grow away from each other or reconnect after time apart both physically and emotionally. Men and women are always adapting.

description: We investigate the density behaviour of the symmetry energy with respect to isospin equilibration in the combined systems $Ru(Zr)+Zr(Ru)$ at relativistic energies of 0.4 and $1.528 AGeV$. The study is performed within a relativistic framework and the contribution of the iso-vector, scalar $δ$ field to the symmetry energy and the isospin dynamics is particularly explored. We find that the isospin mixing depends on the symmetry energy and a stiff behaviour leads to more transparency. The results are also nicely sensitive to the "fine structure" of the symmetry energy, i.e. to the covariant properties of the isovector meson fields. The isospin tracing appears much less dependent on the in-medium neutron-proton cross-sections ($σ_{np}$) and this makes such observable very peculiar for the study of the isovector part of the nuclear equation of state. Within such a framework, comparisons with experiments support the introduction of the $δ$ meson in the description of the iso-vector equation of state.

title: Sugar, spice and everything nice? : an inclusive feminist relational ontological examination of gendered moral agency within stories of evil
Creators: name: Wilson, Rebecca Adele
Publisher: name: University of St Andrews
Year: 2019

description: This thesis challenges the dominant narratives of evil, highlighting how the masculine approach to telling stories of evil has silenced moral agency. It does so through an inclusive feminist relational ontology framework, born from a study of care ethics. The thesis argues the need for an ontological relational feminist approach over a general feminist approach. Here, it engages with the work of Joan Tronto, Fiona Robinson, Margaret Urban Walker and Kimberly Hutchings to highlight the many merits of a feminist relational ontology. However, it also responds to the shortcomings of a feminist relational ontology approach, by engaging with critical (poststructural, queer, postcolonial and black) feminist literature to create an inclusive feminist relational ontology framework. Furthermore, this methodological framework is used to facilitate a discussion of evil in western thought, examining key points in the literature, and how this has led to the dominant narrative of evil within (Feminist) International Relations. It not only highlights the historical contextualization of evil and women, but how the study of evil, within moral theory, is itself gendered. Here, it is argued that the masculine approach to evil is rooted in abstraction and ambiguity, with the rational autonomous man as the primary agent. Therefore, through an inclusive feminist relational ontology framework, it shows how this masculine approach to narrating evil has silenced moral agency. Additionally, this thesis evidences how stories of evil silence moral agency, by scrutinising two case studies. The first explores a very different story of evil; rape culture in the west. Employment of an inclusive feminist relational ontology framework shows how cultural, patriarchal and racist norms have shaped societies, with a focus on the UK, leading to a single real rape narrative. Despite this, most attacks of sexual violence are incompatible with this narrative, meaning that the moral agency of both victims and perpetrators of rape is dissipated. The second case study explores the narratives around Ugandan rebel leader Alice Auma/Lakwena. It highlights, through the use of an inclusive feminist relational ontology framework, that postcolonial legacies and gendered norms have constructed moral boundaries around Alice’s complicated story. This hinders readers from seeing her as a moral agent in her decision making during her leadership of the Holy Spirit Movement and quest to banish evil from the world. Finally, a discussion of how this investigation questions our understanding of evil highlights power hierarchies within stories of evil and explores how many stories are externalized. Overall, this thesis calls for an opening of stories, even of evil, to allow for moral agency to be seen.
Anomalous patterns of horn asymmetry reflects character's unique evolutionary history
Creators: name: Koury, Spencer Arran
Publisher: name: American University
Year: 2023

description: The Developmental Instability-Sexual Selection hypothesis was tested by examining ungulate horn and skeletal morphology. Comparative methods were employed to analyze patterning in asymmetry for eight species of the bovid subfamily Antilopinae. Traits were partitioned into craniofacial or horn groupings; unsigned asymmetries of traits were combined into composite FA indices representing developmental instability of craniofacial and horn modules, respectively. Although horns uniformly exhibited greater asymmetry than craniofacial traits, no evidence supporting subsequent predictions was found. Comparative and correlative analysis of phenotypic variation was performed to further investigate the specific deviations from expectation. The highly variable and asymmetrical female horns were found to be anomalous, while absence of predicted male horn patterns negated explanation with current theory. The anomalous patterns and erroneous predictions were further documented in 40 species for the family Bovidae. A rescue hypothesis was then adduced for variability and asymmetry in secondary sexual characters expressed in females.

description: Type Ia Supernovae (SNe Ia) are powerful standardizable candles for constraining cosmological models and provided the first evidence of the accelerated expansion of the universe. Their precision derives from empirical correlations, now measured from $>1000$ SNe Ia, between their luminosities, light-curve shapes, colors and most recently with the stellar mass of their host galaxy. As mass correlates with other galaxy properties, alternative parameters have been investigated to improve SN Ia standardization though none have been shown to significantly alter the determination of cosmological parameters. We re-examine a recent claim, based on 34 SN Ia in nearby passive host galaxies, of a 0.05 mag/Gyr dependence of standardized SN Ia luminosity on host age which if extrapolated to higher redshifts, would be a bias up to 0.25 mag, challenging the inference of dark energy. We reanalyze this sample of hosts using both the original method and a Bayesian hierarchical model and find after a fuller accounting of the uncertainties the significance of a dependence on age to be $\leq2σ$ and $\sim1σ$ after the removal of a single poorly-sampled SN Ia. To test the claim that a trend seen in old stellar populations can be applied to younger ages, we extend our analysis to a larger sample which includes young hosts. We find the residual dependence of host age (after all standardization typically employed for cosmological measurements) to be consistent with zero for 254 SNe Ia from the Pantheon sample, ruling out the large but low significance trend seen in passive hosts.

description: We investigate photodetachment from negative ions in a homogeneous 1.0-T magnetic field and a parallel electric field of approximately 10 V/cm. A theoretical model for detachment in combined fields is presented. Calculations show that a field of 10 V/cm or more should considerably diminish the Landau structure in the detachment cross section. The ions are produced and stored in a Penning ion trap and illuminated by a single-mode dye laser. We present preliminary results for detachment from S- showing qualitative agreement with the model. Future directions of the work are also discussed.

title: Third level education in Irish prisons: who participates and why?
Creators: name: Costelloe, Anne
Publisher: name: The Open University
Year: 2003

description: This exploratory study examines the reality of third level education for Irish prisoners. It is based on the perspectives of the prison students and the focus is on the students, their experiences, motivations and perceptions rather than on the actual provision. While comparisons and contrasts are drawn with the mainstream situation, the intent at all times is to increase an understanding of the impact of the prison context. As the title suggests, the research embraces two broad foci. It calculates and establishes a pattern of participation for prisoners engaged in third level study in Irish prisons, and it provides an ethnography of the experiences and motivations of third level prison students. The research ideologies framing the study are postmodern in influence, qualitative in approach and fall within the critical research paradigm. Both qualitative and quantitative methods have been employed to collect and analyse the data, the choice of method being determined by the specific research question. In general quantitative methods were used to construct a picture of the typical third level prison student. Qualitative methods were used to identify and examine the motivations of a sub sample of those prison students. It was concluded that the prison pattern of participation emulates the mainstream situation in its under-representation of traditional non-participants. It was seen that the motivations of those traditional non-participants that do participate are influenced primarily by the prison context while in general the motivations of the traditional participants mirror those of mainstream mature students. The research draws on and applies a rich body of theoretical literature concerned with the dynamics of adult learning and the substantive issues of social exclusion, participation and motivation.

description: We propose a general procedure to construct noncommutative deformations of an embedded submanifold $M$ of $\mathbb{R}^n$ determined by a set of smooth equations $f^a(x)=0$. We use the framework of Drinfel'd twist deformation of differential geometry of [Aschieri et al., Class. Quantum Gravity 23 (2006), 1883]; the commutative pointwise product is replaced by a (generally noncommutative) $\star$-product determined by a Drinfel'd twist. The twists we employ are based on the Lie algebra $Ξ_t$ of vector fields that are tangent to all the submanifolds that are level sets of the $f^a$; the twisted Cartan calculus is automatically equivariant under twisted tangent infinitesimal diffeomorphisms. We can consistently project a connection from the twisted $\mathbb{R}^n$ to the twisted $M$ if the twist is based on a suitable Lie subalgebra $\mathfrak{e}\subsetΞ_t$. If we endow $\mathbb{R}^n$ with a metric then twisting and projecting to the normal and tangent vector fields commute, and we can project the Levi-Civita connection consistently to the twisted $M$, provided the twist is based on the Lie subalgebra $\mathfrak{k}\subset\mathfrak{e}$ of the Killing vector fields of the metric; a twisted Gauss theorem follows, in particular. Twisted algebraic manifolds can be characterized in terms of generators and polynomial relations. We present in some detail twisted cylinders embedded in twisted Euclidean $\mathbb{R}^3$ and twisted hyperboloids embedded in twisted Minkowski $\mathbb{R}^3$ [these are twisted (anti-)de Sitter spaces $dS_2,AdS_2$].

description: We provide an analysis of the electromagnetic modes of three-dimensional metamaterial resonators in the THz frequency range. The fundamental resonance of the structures is fully described by an analytical circuit model, which not only reproduces the resonant frequencies but also the coupling of the metamaterial with an incident THz radiation. We also evidence the contribution of the propagation effects, and show how they can be reduced by design. In the optimized design the electric field energy is lumped into ultra-subwavelength ($λ$/100) capacitors, where we insert semiconductor absorber based on the collective electronic excitation in a two dimensional electron gas. The optimized electric field confinement is evidenced by the observation of the ultra-strong light-matter coupling regime, and opens many possible applications for these structures for detectors, modulators and sources of THz radiation.

description: Constrained Hamiltonian systems are investigated by using the Hamilton-Jacobi method. Integration of a set of equations of motion and the action function is discussed. It is shown that we have two types of integrable systems: a) ${\it Partially integrable systems}$, where the set of equations of motion is only integrable. b) {\it Completely integrable systems}, where the set of equations of motion and the action function is integrable. Two examples are studied.

Temperature distribution inside a double-cladding optical fiber laser or amplifier

description: The temperature distribution inside a double-cladding optical fiber laser or amplifier is examined in detail. Traditionally, the quantum defect in the core is taken to be the main source of heating in an active optical fiber. However, contributions from the parasitic absorption of the signal and the pump may also play an important role, especially for low quantum defect or radiation-balanced lasers and amplifiers. The contributions to the heating in both the core and the inner-cladding are considered and analyzed in general terms in this paper. In particular, it is shown that if the maximum tolerable surface temperature of the fiber relative to the ambient is taken to be 300 degrees Celsius to avoid damaging the fiber's outer polymer cladding, the core temperature rises only in the range of 0-5 degrees Celsius relative to the inner-cladding for an air-cooled fiber. However, for a water-cooled fiber, the core temperature can be higher than the inner-cladding by as much as 50 degrees Celsius, potentially changing a single-mode core to multimode due to the thermo-optic effect.

description: We report the first low temperature magnetotransport measurements on electrochemically fabricated atomic scale gold nanojunctions. As $T \to 0$, the junctions exhibit nonperturbatively large zero bias anomalies (ZBAs) in their differential conductance. We consider several explanations and find that the ZBAs are consistent with a reduced local density of states (LDOS) in the disordered metal. We suggest that this is a result of Coulomb interactions in a granular metal with moderate intergrain coupling. Magnetoconductance of atomic scale junctions also differs significantly from that of less geometrically constrained devices, and supports this explanation.

description: Research has shown that both high school and university students' reasoning patterns regarding direct current resistive electric circuits often differ from the currently accepted explanations. At present, there are no standard diagnostic examinations in electric circuits. Two versions of a diagnostic instrument called Determining and Interpreting Resistive Electric circuits Concepts Tests (DIRECT) were developed, each consisting of 29 questions. The information provided by the exam provides classroom instructors a means with which to evaluate the progress and conceptual difficulties of their students and their instructional methods. It can be used to evaluate curricular packages and/or other supplemental materials for their effectiveness in overcoming students' conceptual difficulties. The analyses indicate that students, especially females, tend to hold multiple misconceptions, even after instruction. During interviews, the idea that the battery is a constant source of current was used most often in answering the questions. Students tended to focus on current in solving the problems and to confuse terms, often assigning the properties of current to voltage and/or resistance. Results indicated that students do not have a clear understanding of the underlying mechanisms of electric circuit phenomena. On the other hand, students were able to translate easily from a "realistic" representation of a circuit to the corresponding schematic diagram.

description: The Developmental Instability-Sexual Selection hypothesis was tested by examining ungulate horn and skeletal morphology. Comparative methods were employed to analyze patterning in asymmetry for eight species of the bovid subfamily Antilopinae. Traits were partitioned into craniofacial or horn groupings; unsigned asymmetries of traits were combined into composite FA indices representing developmental instability of craniofacial and horn modules, respectively. Although horns uniformly exhibited greater asymmetry than craniofacial traits, no evidence supporting subsequent predictions was found. Comparative and correlative analysis of phenotypic variation was performed to further investigate the specific deviations from expectation. The highly variable and asymmetrical female horns were found to be anomalous, while absence of predicted male horn patterns negated explanation with current theory. The anomalous patterns and erroneous predictions were further documented in 40 species for the family Bovidae. A rescue hypothesis was then adduced for variability and asymmetry in secondary sexual characters expressed in females.
