description: Esta tesis doctoral aborda la necesidad de elaborar recursos terminológicos dirigidos a traductores para satisfacer sus necesidades concretas a la hora de realizar traducciones de textos especializados. En este sentido, ofrece un estudio de los diferentes recursos terminológicos disponibles en la actualidad y propone una metodología de trabajo basada en la ontoterminografía para elaborar dichos recursos. Así, en el capítulo I se lleva a cabo una revisión exhaustiva del estado de la cuestión en terminología y terminografía, concretamente en la terminografía basada en corpus y la terminografía basada en ontologías, y se analiza la influencia de las disciplinas lingüísticas afines: la Lingüística de Corpus, la Lingüística Computacional y la Lingüística Cognitiva. El capítulo II se centra en las competencias traductoras y en las necesidades documentales de los traductores a la hora de realizar traducciones de calidad y propone una metodología basada en la ontoterminografía para elaborar recursos terminológicos para traductores según los resultados de una encuesta ad hoc realizada para conocer las necesidades y expectativas de estos usuarios. Tras el establecimiento de la propuesta metodológica en el capítulo II, en los siguientes capítulos se presenta la aplicación de dicha metodología en un dominio específico: el turismo de aventura, y para unas lenguas de trabajo determinadas: español, inglés y alemán. En el último capítulo, además, se procede al diseño, implementación y evaluación de una aplicación informática integradora, flexible y novedosa (Trandix) a fin de satisfacer las necesidades de los traductores con respecto a la búsqueda y consulta terminológica.

description: Objective:To identify and compare health-economic models that were developed to evaluate the cost-effectiveness of treatments for type 2 diabetes mellitus (T2DM), and their use within Health Technology Assessments (HTAs).Methods:In total, six commonly used databases were searched for articles published between October 2008 and January 2013, using a protocolized search strategy and inclusion criteria. The websites of HTA organizations in nine countries, and proceedings from five relevant conferences, were also reviewed. The identified new health-economic models were qualitatively assessed using six criteria that were developed based on technical components, and characteristics related to the disease or the treatments being assessed. Finally, the number of times the models were applied within HTA reports, published literature, and/or major conferences was determined.Results:Thirteen new models were identified and reviewed in depth. Most of these were based on identical key data sources, and applied a similar model structure, either using Markov modeling or microsimulation techniques. The UKPDS equations and panel regressions were frequently used to estimate the occurrence of diabetes-related complications and the probability of developing risk factors in the long term. The qualitative assessment demonstrated that the CARDIFF, Sheffield T2DM and ECHO T2DM models seem technically equipped to appropriately assess the long-term health-economic consequences of chronic treatments for patients with T2DM. It was observed that the CORE model is the most widely described in literature and conferences, and the most often applied model within HTA submissions, followed by the CARDIFF and UKPDS models.Conclusion:This research provides an overview of T2DM models that were developed between 2008 and January 2013. The outcomes of the qualitative assessments, combined with frequent use in local reimbursement decisions, prove the applicability of the CORE, CARDIFF and UKPDS models to address decision problems related to the long-term clinical and economic consequences of new and existing T2DM treatments.

description: ABSTRACTMagneto-structural correlations in oxygen-evolving complex (OEC) of photosystem II (PSII) have been elucidated on the basis of theoretical and computational results in combination with available electron paramagnetic resonance (EPR) experimental results, and extended x-ray absorption fine structure (EXAFS) and x-ray diffraction (XRD) results. To this end, the computational methods based on broken-symmetry (BS) UB3LYP solutions have been developed to elucidate magnetic interactions in the active manganese catalyst for water oxidation by sunlight. The effective exchange interactions J for the CaMn(III)Mn(IV)3O5(H2O)3Y(Y = H2O or OH−) cluster (1) model of OEC of PSII have been calculated by the generalised approximate spin projection (GAP) method that eliminates the spin contamination errors of the BS UB3LYP solution. Full geometry optimisations followed by the zero-point energy (ZPE) correction have been performed for all the spin configurations of 1 to improve the J values that are compared with accumulated EPR in the S2 state of Kok cycle and magnetic susceptibility results of Christou model complex Ca2Mn(IV)3O4 (2). Using the calculated J values, exact diagonalisation of the spin Hamiltonian matrix has been carried out to obtain excitation energies and spin densities of the ground and lower excited states of 1. The calculated excitation energies are consistent with the available experimental results. The calculated spin densities (projection factors) are also compatible with those of the EPR results. The calculated spin densities have been used to calculate the isotropic hyperfine (Aiso) constants of 55Mn ions revealed by the EPR experiments. Implications of the computational results are discussed in relation to the structural symmetry breaking (SSB) in the S1, S2 and S3 states, spin crossover phenomenon induced by the near-infrared excitation and the right- and left-handed scenarios for the O–O bond formation for water oxidation.

description: This thesis addresses the substantial mental health crisis that college students have been facing by employing a “stealth health” perspective. “Stealth health” refers to an activity that fosters mental or physical
wellness without the direct intention of deliberately improving the individual’s health. While prior research has been published on the potential of using birding as a non-pharmaceutical treatment for mental health, this
innovative research specifically delves into the unique impacts of birding on college student's mental health. This study employed a focus group methodology to engage with self-identified student birders, which allowed
for direct feedback from the target population. Participants who reported going birding at least once every two weeks described how going birding has impacted their lives mentally, physically, socially, and academically.
Participants comprised both undergraduate and graduate students. This study highlights the versatility of birding as a tool for social well-being, mental health, and physical health. A significant emphasis is placed on the
meditative impact that birding has on individuals. The findings of this research may be valuable to student affairs practitioners concerned with enhancing students' well-being and campus planning professionals responsible for shaping campus environments. These insights will support the enhancement of student success and encourage a focus on bird habitat and environmental conservation.

description: Purpose Radiation exposure, besides the risk of cancer, may also increase the risk of non-cancer diseases, including cardiovascular disease (CVD). This study investigates whether the soluble form of the ST2 receptor (sST2), an emerging prognostic marker in patients with CVD, can be used to monitor the CVD risk in individuals occupationally exposed to radiation.Materials and methods sST2 in blood plasma from 69 individuals, 45 workers from the nuclear industry and 24 controls, was analyzed using enzyme-linked assay (ELISA). Total antioxidant status (TAS) of blood plasma and levels of reactive oxygen species (ROS) in lymphocytes were determined by colorimetric and fluorescence assays.Results The data suggest a 5-fold increase in the number of subjects with sST2 levels above the clinical threshold and a 10-fold increase in the number of subjects with TAS levels outside the reference range in the exposed group when compared to the group of non-exposed individuals. The strongest up-regulation of TAS was measured in the group of younger workers with cumulative doses not exceeding 50 mSv.Conclusion The present study may represent an initial step towards the establishment of sST2 as a biomarker for CVD risk estimation in the context of radiation exposure.

description: This document introduces the “Mouhaman’s Quantium Principle”, a new theoretical perspective on black holes and Hawking radiation. Contrary to the common assumption that information is lost inside black holes, this theory proposes that all matter absorbed is decomposed into pure energy and a unique quantum imprint. During Hawking radiation, this imprint helps reconstruct the original matter, preserving information. This principle suggests the possibility of re-creating specific matter from energy, opening new paths in quantum physics and energy-to-matter conversion.

description: Objective: To compare speech reception thresholds (SRTs) in noise using matrix sentence tests in four languages: German, Spanish, Russian, Polish. Design: The four tests were composed of equivalent five-word sentences and were all designed and optimized using the same principles. Six stationary speech-shaped noises and three non-stationary noises were used as maskers. Study sample: Forty native listeners with normal hearing: 10 for each language. Results: SRTs were about 3 dB higher for the German and Spanish tests than for the Russian and Polish tests when stationary noise was used that matched the long-term frequency spectrum of the respective speech test materials. This general SRT difference was also observed for the other stationary noises. The within-test variability across noise conditions differed between languages. About 56% of the observed variance was predicted by the speech intelligibility index. The observed SRT benefit in fluctuating noise was similar for all tests, with a slightly smaller benefit for the Spanish test. Conclusions: Of the stationary noises employed, noise with the same spectrum as the speech yielded the best masking. SRT differences across languages and noises could be attributed in part to spectral differences. These findings provide the feasibility and limits of comparing audiological results across languages.

description: The oxidation and spin state of a metal–organic molecule determine its chemical reactivity and magnetic properties. Here, we demonstrate the reversible control of the oxidation and spin state in a single Fe porphyrin molecule in the force field of the tip of a scanning tunneling microscope. Within the regimes of half-integer and integer spin state, we can further track the evolution of the magnetocrystalline anisotropy. Our experimental results are corroborated by density functional theory and wave function theory. This combined analysis allows us to draw a complete picture of the molecular states over a large range of intramolecular deformations.

description: The Mo/Cu-dependent CO dehydrogenase (CODH) from Oligotropha carboxidovorans is an enzyme that is able to catalyze both the oxidation of CO to CO2 and the oxidation of H2 to protons and electrons. Despite the close to atomic resolution structure (1.1 Å), significant uncertainties have remained with regard to the reaction mechanism of substrate oxidation at the unique Mo/Cu center, as well as the nature of intermediates formed during the catalytic cycle. So far, the investigation of the role of amino acids at the active site was hampered by the lack of a suitable expression system that allowed for detailed site-directed mutagenesis studies at the active site. Here, we report on the establishment of a functional heterologous expression system of O. carboxidovorans CODH in Escherichia coli. We characterize the purified enzyme in detail by a combination of kinetic and spectroscopic studies and show that it was purified in a form with characteristics comparable to those of the native enzyme purified from O. carboxidovorans. With this expression system in hand, we were for the first time able to generate active-site variants of this enzyme. Our work presents the basis for more detailed studies of the reaction mechanism for CO and H2 oxidation of Mo/Cu-dependent CODHs in the future.

description: The well-studied enterobacterium Escherichia coli present in the human gut can reduce trimethylamine N-oxide (TMAO) to trimethylamine during anaerobic respiration. The TMAO reductase TorA is a monomeric, bis-molybdopterin guanine dinucleotide (bis-MGD) cofactor-containing enzyme that belongs to the dimethyl sulfoxide reductase family of molybdoenzymes. We report on a system for the in vitro reconstitution of TorA with molybdenum cofactors (Moco) from different sources. Higher TMAO reductase activities for TorA were obtained when using Moco sources containing a sulfido ligand at the molybdenum atom. For the first time, we were able to isolate functional bis-MGD from Rhodobacter capsulatus formate dehydrogenase (FDH), which remained intact in its isolated state and after insertion into apo-TorA yielded a highly active enzyme. Combined characterizations of the reconstituted TorA enzymes by electron paramagnetic resonance spectroscopy and direct electrochemistry emphasize that TorA activity can be modified by changes in the Mo coordination sphere. The combination of these results together with studies of amino acid exchanges at the active site led us to propose a novel model for binding of the substrate to the molybdenum atom of TorA.

description: The oxidoreductase YdhV in Escherichia coli has been predicted to belong to the family of molybdenum/tungsten cofactor (Moco/Wco)-containing enzymes. In this study, we characterized the YdhV protein in detail, which shares amino acid sequence homology with a tungsten-containing benzoyl-CoA reductase binding the bis-W-MPT (for metal-binding pterin) cofactor. The cofactor was identified to be of a bis-Mo-MPT type with no guanine nucleotides present, which represents a form of Moco that has not been found previously in any molybdoenzyme. Our studies showed that YdhV has a preference for bis-Mo-MPT over bis-W-MPT to be inserted into the enzyme. In-depth characterization of YdhV by X-ray absorption and electron paramagnetic resonance spectroscopies revealed that the bis-Mo-MPT cofactor in YdhV is redox active. The bis-Mo-MPT and bis-W-MPT cofactors include metal centers that bind the four sulfurs from the two dithiolene groups in addition to a cysteine and likely a sulfido ligand. The unexpected presence of a bis-Mo-MPT cofactor opens an additional route for cofactor biosynthesis in E. coli and expands the canon of the structurally highly versatile molybdenum and tungsten cofactors.

description: B12-dependent proteins are involved in methyl transfer reactions ranging from the biosynthesis of methionine in humans to the formation of acetyl-CoA in anaerobic bacteria. During their catalytic cycle, they undergo large conformational changes to interact with various proteins. Recently, the crystal structure of the B12-containing corrinoid iron–sulfur protein (CoFeSP) in complex with its reductive activator (RACo) was determined, providing a first glimpse of how energy is transduced in the ATP-dependent reductive activation of corrinoid-containing methyltransferases. The thermodynamically uphill electron transfer from RACo to CoFeSP is accompanied by large movements of the cofactor-binding domains of CoFeSP. To refine the structure-based mechanism, we analyzed the conformational change of the B12-binding domain of CoFeSP by pulsed electron–electron double resonance and Förster resonance energy transfer spectroscopy. We show that the site-specific labels on the flexible B12-binding domain and the small subunit of CoFeSP move within 11 Å in the RACo:CoFeSP complex, consistent with the recent crystal structures. By analyzing the transient kinetics of formation and dissociation of the RACo:CoFeSP complex, we determined values of 0.75 μM–1 s–1 and 0.33 s–1 for rate constants kon and koff, respectively. Our results indicate that the large movement observed in crystals also occurs in solution and that neither the formation of the protein encounter complex nor the large movement of the B12-binding domain is rate-limiting for the ATP-dependent reductive activation of CoFeSP by RACo.

description: We perform atomistic simulations of nanometer-separated charged surfaces in the presence of monovalent counterions at fixed water chemical potential. The counterion density profiles are well described by a modified Poisson–Boltzmann (MPB) approach that accounts for nonelectrostatic ion–surface interactions, while the effects of smeared-out surface-charge distributions and dielectric profiles are found to be relatively unimportant. The simulated surface interactions are for weakly charged surfaces well described by the additive contributions of hydration and MPB repulsions, but already for a moderate surface charge density of σ = −0.77 e/nm2 this additivity breaks down. This we rationalize by a combination of different effects, namely, counterion correlations as well as the surface charge-induced reorientation of hydration water, which modifies the effective water dielectric constant as well as the hydration repulsion.
title: Protection in the name of efficiency can the UN's immunities continue to be justified by functional necessity?
Creators: name: Guichardaz, Héloïse Colombine
Publisher: name: University of Glasgow

description: In 2010, following a devastating earthquake, the United Nations (UN) was accused of bringing and spreading cholera in Haiti via a contingent of peacekeepers. Following a long process that involved the UN factually denying that it was responsible for the introduction of the disease, the claimants, a group of Haitians who had been directly or indirectly affected by the disease, went to court in the US. In 2016, the court of appeals ruled that the UN could not be compelled to deliver reparations, as it benefited from absolute immunity. In making this decision, the court followed both the Convention on Privileges and Immunities of the United Nations (also called the General Convention) and the recommendations of the US government, buttressed by previous cases such as the lead poisoning scandal in Kosovo that emerged in the late 1990s, also caused by the UN and for which they also escaped demands for reparations.

This decision as well as the reaction of the UN was harshly criticised by NGOs, the media, and the academic literature. Yet despite the nature of the claims, the number of victims, and the increasing involvement of peacekeepers in the daily lives of vulnerable populations leading to more opportunities to cause harm, there is a general unease in questioning the necessity of absolute immunity for the UN. The doctrine, courts, and the UN itself all participate in maintaining the idea that the UN requires the broadest scope of immunity in order to function, as if the UN was still an emerging organisation in need of protection. This narrative of functional necessity has permeated the discussions on UN reform, and influenced most reform proposals to focus on a better implementation of the existing rules.

Despite this lack of change, there is a real risk that a situation like Haiti and Kosovo could happen again. This thesis therefore critically assesses the narrative of functional necessity, and argues that as the organisation and its range of action have evolved, it is now obsolete. Taking inspirations from other organisations but to a greater extent from States - entities which have seen their once absolute immunity reduce over time - this thesis will propose a reform based on restricting the immunity of the UN and advocating for an independent judicial body to be established in order to examine the claims that inevitably follow. The objective is to take into account both the UN's unique nature and its main goals, with the overarching argument being that if no move towards reparations is taken, the crippling effect on the UN would end up far more dangerous and costly for the organisation and its goals.

description: The magnetic properties of Mn–Na2WO4/SiO2, a promising catalyst for the oxidative coupling of methane (OCM), were investigated in two states: reduced with CH4 until reactivity ceased and reoxidized with O2 to probe for state-specific magnetic species and their involvement in the oxygen storage of the catalyst. Employing temperature- and frequency-dependent continuous-wave (cw) and pulsed electron paramagnetic resonance (EPR) spectroscopy combined with SQUID (Superconducting Quantum Interference Device) magnetization measurements allowed us to identify a variety of Mn species in different oxidation states and their role in the oxygen storage capability of the catalyst. For the reoxidized catalyst, the formation of magnetically ordered Mn(II)- and Mn(III)-containing Mn3O4 as well as Mn2O3 or MnMn6SiO12 phases were detected. The reduced catalyst exhibits almost ideal paramagnetic behavior and a strong, broad cw EPR signal consistent with the formation of short-range ordered nanosized Mn(II) oxide, demonstrating the involvement of these Mn species in the oxygen storage capability of the catalyst. In contrast, rather isolated, highly oxidized Mn(IV) as well as different Mn(III) species were observed by pulsed EPR, which are not affected by the oxidation state of the Mn–Na2WO4/SiO2 catalyst, suggesting an inaccessible, buried location, presumably in the SiO2 support. Furthermore, paramagnetic sites with an effective S = 1/2 spin are detected, whose intensity depends on the oxidation state of the sample and are thus involved in the oxygen storage capacity of the catalyst.

description: The detection of vibrational excitations of individual molecules on surfaces by scanning tunneling spectroscopy does not obey strict selection rules but rather propensity rules. The experimental verification of these excitations is challenging because it requires the independent variation of specific parameters, such as the electronic structure, while keeping the vibrational modes the same. Here, we make use of the versatile self-assembled structures of Fe-tetra-pyridyl-porphyrin molecules on a Au(111) surface. These molecules exhibit different energy-level alignments of the frontier molecular orbitals, thus allowing the correlation of the electronic structure and detection of vibrations. We identify up to seven vibrational modes in the tunneling spectra of the molecules in some of the arrangements, whereas we observe none in other structures. We find that the presence of vibrational excitations and their distribution along the molecule correlate with the observation of energetically low-lying molecular states. This correlation allows the explanation of the different numbers of vibrational signatures for molecules embedded within different structures as well as the bias asymmetry of the vibrational intensities within an individual molecule. Our observations are in agreement with the resonant enhancement of vibrations by the virtual excitation of electronic states.
Management of Thy3 thyroid nodules: systematic review and meta-analysis

description: The diagnostic work up of thyroid nodules very often leads to indeterminate cytological diagnoses (Thy3) and uncertainty in defining the appropriate management option. Thy3 nodules have a wide range of malignancy proportions. Approximately, 15-30% of Thy3f and 5-15% of Thy3a nodules are expected to be malignant. Moreover, the expected malignancy proportions and that reported across studies is very variable thereby adding complexity regarding treatment decision making. 

The aim of this study is to perform a systematic review of the literature and a meta-analysis on the proportion of Thy3 nodules (including Thy3a and Thy3f subclassifications) that are malignant, to guide clinical management of indeterminate cytological diagnosis. The secondary aim of this project is to determine if the proportion of malignancies varies in relation to certain clinical characteristics of the patient and of the nodule.

description: Nonlinear Fourier Transform (NFT) is originally applicable to integrable equations such as lossless optical fiber. The lossy propagation of a signal is not suitable for NFT. Conventionally, the path average model is used to approximate lossy propagation of signal as lossless propagation As the model is an approximation, perfect nonlinearity compensation can not be achieved even in the absence of
 noise. The approximation error associated with path average model increases with signal power, bandwidth and
 length of span It imposes an additional limit on system design parameters. In this poster, I present how dispersion decreasing fiber can be used to make the NFT based transmission system avoiding the aforementioned approximation errors.

description: Research over the last decade has shown a sharp increase in mental health issues amongst
university students, and several studies corroborate a common perception that these issues are
more prevalent, or are experienced more intensely, amongst computer science students. Common
explanations for this rise include rigorous academic expectations, intense competition, the
isolated nature of programming tasks, the rapidly changing industry, and particular physical
health challenges. While prior research has considered and analyzed the mental health issues of
student subgroups such as STEM fields and health sciences, no study has yet examined the
prevalence and impact of the five possible stressors listed above for computer science students.
This study addresses this gap by surveying undergraduate computer science students at a large
research university to examine the commonality and frequency of stressors for computer science
students. The survey will consist of a variety of questions, including multiple-choice, Likert scale
rankings, and short responses. The findings of this study can be used to raise awareness about the
sources of mental health issues in the computer science student community and inform
discussions about possible interventions. Findings may also be valuable to university staff and
administration to create programming and policies that support student well-being.

description: Sauropus androgynus L. Merr is an underexploited medicinal shrub from the Phyllanthaceae family, often referred to both as a leafy vegetable and as a kind of multivitamin-rich green plant. Compounds having anti-inflammatory, anti-diabetic, anti-microbial, wound-healing, and anti-obesity properties can be found in abundance in S. androgynous leaf extracts. Furthermore, these extracts may also enhance breast milk production. Micronutrient and vitamin deficiencies are prevalent across the globe, particularly impacting women and children who frequently experience malnutrition due to inadequate vegetable intake. Green leafy vegetables (GLVs) are significantly neglected in diets while being a rich source of minerals and vitamins. Their high-water content causes them to spoil quickly, emphasizing the necessity of processing these greens to enhance their value and encourage their inclusion in everyday meals. Chekurmanis is a highly nutritious green leafy vegetable that remains largely overlooked.

description: The organophosphorus antidotes, so-called oximes, are able to restore the enzymatic function of acetylcholinesterase (AChE) or butyrylcholinesterase (BChE) via cleavage of organophosphate from the active site of the phosphylated enzyme. In this work, the charged pyridinium oximes containing thiocarboxamide moiety were designed, prepared and tested. Their stability and pKa properties were found to be analogous to parent carboxamides (K027, K048 and K203). The inhibitory ability of thiocarboxamides was found in low µM levels for AChE and high µM levels for BChE. Their reactivation properties were screened on human recombinant AChE and BChE inhibited by nerve agent surrogates and paraoxon. One thiocarboxamide was able to effectively restore function of NEMP- and NEDPA-AChE, whereas two thiocarboxamides were able to reactivate BChE inhibited by all tested organophosphates. These results were confirmed by reactivation kinetics, where thiocarboxamides were proved to be effective, but less potent reactivators if compared to carboxamides.

description: BACKGROUND: Technologies such as the Internet, smartphones, and sex toys have demonstrated the capacity to facilitate and enhance sexual and intimate practice by offering new ways to meet sexual partners, maintain and establish intimate connections, and providing access to sexual education and exposure to new ways of engaging in sex. They have also afforded novel risks to safety, privacy, and sexual autonomy. Understanding how people perceive and experience both the risks and benefits of using technology to facilitate sex and intimacy is important to understanding contemporary sexual practice, health, and pleasure. However, research in this space is currently hampered by a lack of quantitative measures to accurately and holistically assess both the risks and benefits in the context of technologised sexual practices. METHODS: To facilitate a nuanced quantitative exploration of these concepts, we present the psychometric properties of the newly developed Risks and Benefits of Technologised Sexual Practice Scale . RESULTS: Using an exploratory (Study 1, n =445) and confirmatory factor analysis (Study 2, n =500), this paper presents evidence for a 6-factor scale (Benefits (3): 'sexual gratification', 'connection', and 'access to information and culture'; Risks (3): 'concerns', 'worries', and 'knowledge of rights and ownership'). CONCLUSION: This scale may be used to contribute to research areas including sexual health, sexual behaviour, sexual education, online connection, online safety, and digital literacy with the aim to contribute to a sex- and technology-positive framework for understanding sexual health and pleasure.

description: The field of ultra-high-energy cosmic ray (UHECR) astronomy has been facing an ongoing challenge due to the unknown impact of magnetic deflections on the observed events. However, with the dawn of the era of mass-sensitive data, we would have the available information to perform UHECR astronomy. To do so, constructing a sophisticated analysis that can accurately reconstruct source parameters will be crucial. In this work, we construct a Bayesian hierarchical framework that utilises the spatial, energy, and mass composition information to infer the source properties such as luminosity or the spectral index as well as the strength of the extragalactic magnetic field while marginalising the uncertainties of the detector. We model the mass-dependent spatial deflections from the Galactic magnetic field (GMF) on an event-by-event basis using the latest available GMF model (Unger & Farrar 2023, ApJ 970 1, 95) and developed a novel method to determine the nuclear composition of each UHECR source by applying the propagation solver PriNCe (Heinze et al. 2019, ApJ 873 1, 88) that incorporates the energy losses due to photo-nuclear interactions. We apply this new method on realistic simulated datasets with nuclear composition information observed in both Northern and Southern skies to demonstrate the method’s capabilities of the Bayesian inference of source parameters. It is shown that leveraging the full three-dimensional mass-sensitive data while incorporating the most accurate physical models of UHECR acceleration and propagation allows a more unbiased reconstruction of source properties and extragalactic magnetic field strengths.

description: This qualitative case study examined the development of the charter school movement in New Jersey, documenting its historical trajectory and the growing relevance of charter schools as a viable option in public education, particularly in urban school districts, from 1990 -2022. The study used Ganz’s (2010, 2011) social movement theory to examine the processes anchoring the emergence and sustainability of charter schools and the trajectory of charter schools in spearheading dynamic change in public education in New Jersey. Spanning from the theoretical perspective that social movements impact social policy directly (Ishakanian, 2022), the study embedded elements of policy research to better understand the relationship of social policy and social movement theory in the factors, policies, political dynamics, actors, and actions that created opportunities for charter schools to emerge and grow in New Jersey. Accordingly, I emphasized the actions of individuals and coalitions that joined to transform the ways in which public education was organized and delivered in some of the most challenged communities in the state. The study used the specific trajectories of the cities of Camden and Newark in developing a robust charter sector that serves some of the most vulnerable students in the state. I derived primary data from two main sources: document review and interviews. This dissertation represents the first case study of the charter school movement documenting New Jersey’s trajectory in advocating and legislating for policy action—resulting in significant change in organizing and delivering public education across the state. Understanding historical trajectories, organizing approaches, and policy impacts was fundamental to broadening discourse on how to best position and establish alternatives for improving K–12 education in urban communities. This study contributed to social movement theory by providing a greater understanding of how and to what extent the charter school movement in New Jersey promoted charter schools as a viable and credible component in public education systems. This study is an important contribution to the fields of social movement and social policy, as it advances understanding of how a combined perspective of these frameworks can enhance social and policy change.
