description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We suggest the most model-independent and simple description of the $γγ\rightarrowππ$ process near threshold in framework of S-matrix approach. The amplitudes contain the pion polarizabilities and rather restricted information about $ππ$ interaction. Application of these formulae for description of MARK-II \cite{M2} and Crystal Ball \cite{CB} data gives: $(α-β)^{C}=(6.0\pm 1.2)\cdot 10^{-42} {\rm cm}^{3}$, $(α-β)^{N}=(-1.4\pm 2.1)\cdot 10^{-42} cm^3$ (in units system $e^2 = 4 πα$) at the experimental values of $ππ$ scattering lengths. Both values are compartible with current algebra predictions.

CREATING OPPORTUNITIES FOR SOCIAL ENGAGEMENT, SERVICES, AND SUPPORT FOR AFRICAN AMERICANS IN VANCE COUNTY, NORTH CAROLINA
Creators: name: Zaynab Qatu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2025

description:
Social isolation and loneliness are growing public health concerns that disproportionately affect African American adults in rural communities. This capstone project explores the social and community context of health in Vance County, North Carolina—a region marked by high social vulnerability, racial health disparities, and limited access to community engagement opportunities. Through a systems-oriented approach, this project identifies social isolation among African American adults as a pressing social determinant of health (SDOH) and analyzes the structural, economic, and historical contributors to this issue. The project includes a comprehensive social determinants of health analysis, a leadership strategy featuring the development of a community-driven steering committee, and a systems-level framework supported by a causal loop diagram. Interventions emphasize expanding transportation access, investing in public spaces, strengthening broadband infrastructure, and leveraging culturally grounded community programs to foster social engagement. Additionally, a visual "rich picture" included in the report illustrates the complexity of the problem and highlights both current barriers and potential solutions. By highlighting key leverage points and barriers, this work outlines a path for county commissioners to create sustainable, equity-driven solutions that promote social connectivity and improve health outcomes for vulnerable populations in Vance County.

description: Topological semimetals (TSMs) in which conduction and valence bands cross at zero-dimensional (0D) Dirac nodal points (DNPs) or 1D Dirac nodal lines (DNLs), in 3D momentum space, have recently drawn much attention due to their exotic electronic properties. Here we generalize the TSM state further to a higher-symmetry and higher-dimensional pseudo Dirac nodal sphere (PDNS) state, with the band crossings forming a 2D closed sphere at the Fermi level. The PDNS state is characterized with a spherical backbone consisting of multiple crossing DNLs while band degeneracy in between the DNLs is approximately maintained by weak interactions. It exhibits some unique electronic properties and low-energy excitations, such as collective plasmons different from DNPs and DNLs. Based on crystalline symmetries, we theoretically demonstrate two possible types of PDNS states, and identify all the possible band crossings with pairs of 1D irreducible representations to form the PDNS states in 32 point groups. Importantly, we discover that strained MH3 (M= Y, Ho, Tb, Nd) and Si3N2 are materials candidates to realize these two types of PDNS states, respectively. As a high-symmetry-required state, the PDNS semimetal can be regarded as the "parent phase" for other topological gapped and gapless states.

description: We are deep into the era of relatively high measured unemployment rates and high rates of inflation that is described by that inelegant term "stagflation." Growth rates of real output fell in Western Europe and the U.S. just at the time that the growth rates of the labor forces increased. The rate of increase in productivity has fallen, so real incomes have either fallen or risen more slowly than in the sixties. Inflation and progressive tax rates financed further increases in the relative size of the public sector with the result that current and prospective taxes have grown more than incomes.

description: We present a new method for regularizing chiral theories on the lattice. The arbitrariness in the regularization is used in order to decouple massless replica fermions. A continuum limit with only one fermion is obtained in perturbation theory and a Golterman-Petcher like symmetry related to the decoupling of the replicas in the non-perturbative regime is identified. In the case of Chiral Gauge Theories gauge invariance is broken at the level of the regularization, so our approach shares many of the characteristics of the Rome approach.

description: We have measured the scintillation properties of 151 young, energetic pulsars with the Parkes radio telescope and have identified two extreme scattering events (ESEs). Towards PSR J1057-5226 we discovered a three-year span of strengthened scattering during which the variability in flux density and the scintillation bandwidth decreased markedly. The transverse size of the scattering region is ~23 au, and strong flux density enhancement before and after the ESE may arise from refractive focusing. Long observations reveal scintillation arcs characteristic of interference between rays scattered at large angles, and the clearest arcs appear during the ESE. The arcs suggest scattering by a screen 100-200 pc from the earth, perhaps ionized filamentary structure associated with the boundary of the local bubble(s). Towards PSR J1740-3015 we observed a "double dip" in the measured flux density similar to ESEs observed towards compact extragalactic radio sources. The observed shape is consistent with that produced by a many-au scale diverging plasma lens with electron density ~500cm$^{-3}$ . The continuing ESE is at least 1500 d long, making it the longest detected event to date. These detections, with materially different observational signatures, indicate that well-calibrated pulsar monitoring is a keen tool for ESE detection and ISM diagnostics. They illustrate the strong rôle au-scale non-Kolmogorov density fluctuations and the local ISM structure play in such events and are key to understanding both their intrinsic physics and their impact on other phenomena, particularly fast radio bursts.

description: We solve a Pareto risk-sharing problem with heterogeneous agents with recursive utility over multiple goods. We use this optimal consumption allocation to derive a pricing kernel and the price of oil and related futures contracts. This gives us insight into the dynamics of risk premia in commodity markets for oil. As an example, in a calibrated version of our model we show how rising oil prices and falling oil risk premium are an outcome of the dynamic properties of the optimal risk sharing solution. We also compute portfolios that implement the optimal consumption policies and demonstrate that large and variable open interest is a property of optimal risk sharing.

description: Identifying strongly connected substructures in large networks provides insight into their coarse-grained organization. Several approaches based on the optimization of a quality function, e.g., the modularity, have been proposed. We present here a multistep extension of the greedy algorithm (MSG) that allows the merging of more than one pair of communities at each iteration step. The essential idea is to prevent the premature condensation into few large communities. Upon convergence of the MSG a simple refinement procedure called "vertex mover" (VM) is used for reassigning vertices to neighboring communities to improve the final modularity value. With an appropriate choice of the step width, the combined MSG-VM algorithm is able to find solutions of higher modularity than those reported previously. The multistep extension does not alter the scaling of computational cost of the greedy algorithm.

description: The quality assessment of edges in an image is an important topic as it helps to benchmark the performance of edge detectors, and edge-aware filters that are used in a wide range of image processing tasks. The most popular image quality metrics such as Mean squared error (MSE), Peak signal-to-noise ratio (PSNR) and Structural similarity (SSIM) metrics for assessing and justifying the quality of edges. However, they do not address the structural and functional accuracy of edges in images with a wide range of natural variabilities. In this review, we provide an overview of all the most relevant performance metrics that can be used to benchmark the quality performance of edges in images. We identify four major groups of metrics and also provide a critical insight into the evaluation protocol and governing equations.

description: This paper explores the venture capital (VC) market and extends the standard principal-agent problem between the investor and venture capitalist to show how it alters the interaction between the venture capitalist and the entrepreneur. The nature of the three way interaction results in a correlation between total risk and investor net of fee returns. Thus, we show how and why diversifiable risk should be priced in VC deals even though investors are fully diversified. We then take our theory to a unique data set and show that there is a strong correlation between realized risk and investor returns, as predicted by the theory.

description: INTRODUCTION:
Self-Care is the core of human occupation when verified in terms of daily life, it is the most intimate expression with everyday life and the relationships that people establish with themselves. The self-care learning approach, as a way to prevent health problems, is necessary as chronic noncommunicable diseases have their incidence increased each year (BRAZIL, 2013). In chronic diseases, successful treatment depends largely on the active participation and commitment of the user. Learning and motivation are central to the individual's ability to change habits and take self-care as a way to prevent health damage. It is in this context of learning and motivation that metacognition can make its contribution, contributing to the understanding and performance in situations found in the occupational therapist's performance.

PURPOSE:
To demonstrate the benefits metacognition can offer for Occupational Therapy, with the purpose of increasing adherence to self-care as a way to prevent health problems in people with chronic diseases.

DISCUSSION:
Given the virtual absence of studies on the subject, we point out, in addition to that presented by Katz and Hartman-Maeir (1997), other benefits that metacognition can offer Occupational Therapy, to increase adherence to self-care, as a way to improve self-care. prevention of health problems: Metacognition collaborates with the historical-social perspective, with emphasis on critical thinking, by stimulating awareness, reflection and management of cognitive processes; Metacognition favors autonomy, as it seeks to value the teaching-learning process; Metacognition enables cognitive self-assessment and self-control, as a form of thought that the person can develop and that allows him to have an active and constructive role in his own knowledge and consequently in self-care.FINAL REMARKS:
What Occupational Therapy can learn from metacognition is that it enables you to become aware of the processes used to learn and also to make appropriate decisions about which strategies to use in each task, and also to assess their validity, making the necessary modifications when the expected results are not achieved.

description: The big new factor in the economy is the President's program« The new program involves enormous changes, including tax incentives for investment, tax cuts for individuals, budget reductions, wage and price controls, a floating dollar, and an import surcharge. The whole adds up to a very stimulative package in an economy that, despite press comments to the contrary, was well on its way to recovery from the very mild recession of 1970. The economy did not require as much additional stimulus as it has received and it is hard to see much relief from inflation in the total package.

Measuring the accretion rate and kinetic luminosity functions of supermassive black holes

description: We derive accretion rate functions (ARFs) and kinetic luminosity functions (KLF) for jet-launching supermassive black holes. The accretion rate as well as the kinetic power of an active galaxy is estimated from the radio emission of the jet. For compact low-power jets, we use the core radio emission while the jet power of high-power radio-loud quasars is estimated using the extended low-frequency emission to avoid beaming effects. We find that at low luminosities the ARF derived from the radio emission is in agreement with the measured bolometric luminosity function (BLF) of AGN, i.e., all low-luminosity AGN launch strong jets. We present a simple model, inspired by the analogy between X-ray binaries and AGN, that can reproduce both the measured ARF of jet-emitting sources as well as the BLF. The model suggests that the break in power law slope of the BLF is due to the inefficient accretion of strongly sub-Eddington sources. As our accretion measure is based on the jet power it also allows us to calculate the KLF and therefore the total kinetic power injected by jets into the ambient medium. We compare this with the kinetic power output from SNRs and XRBs, and determine its cosmological evolution.

description: A biperiodic alternating link has an alternating quotient link in the thickened torus. In this paper, we focus on semi-regular links, a class of biperiodic alternating links whose hyperbolic structure can be immediately determined from a corresponding Euclidean tiling. Consequently, we determine the exact volumes of semi-regular links. We relate their commensurability and arithmeticity to the corresponding tiling, and assuming a conjecture of Milnor, we show there exist infinitely many pairwise incommensurable semi-regular links with the same invariant trace field. We show that only two semi-regular links have totally geodesic checkerboard surfaces; these two links satisfy the Volume Density Conjecture. Finally, we give conditions implying that many additional biperiodic alternating links are hyperbolic and admit a positively oriented, unimodular geometric triangulation. We also provide sharp upper and lower volume bounds for these links.

Unsupervised Classification of PolSAR Data Using a Scattering Similarity Measure Derived from a Geodesic Distance

description: In this letter, we propose a novel technique for obtaining scattering components from Polarimetric Synthetic Aperture Radar (PolSAR) data using the geodesic distance on the unit sphere. This geodesic distance is obtained between an elementary target and the observed Kennaugh matrix, and it is further utilized to compute a similarity measure between scattering mechanisms. The normalized similarity measure for each elementary target is then modulated with the total scattering power (Span). This measure is used to categorize pixels into three categories i.e. odd-bounce, double-bounce and volume, depending on which of the above scattering mechanisms dominate. Then the maximum likelihood classifier of [J.-S. Lee, M. R. Grunes, E. Pottier, and L. Ferro-Famil, Unsupervised terrain classification preserving polarimetric scattering characteristics, IEEE Trans. Geos. Rem. Sens., vol. 42, no. 4, pp. 722731, April 2004.] based on the complex Wishart distribution is iteratively used for each category. Dominant scattering mechanisms are thus preserved in this classification scheme. We show results for L-band AIRSAR and ALOS-2 datasets acquired over San Francisco and Mumbai, respectively. The scattering mechanisms are better preserved using the proposed methodology than the unsupervised classification results using the Freeman-Durden scattering powers on an orientation angle (OA) corrected PolSAR image. Furthermore, (1) the scattering similarity is a completely non-negative quantity unlike the negative powers that might occur in double- bounce and odd-bounce scattering component under Freeman Durden decomposition (FDD), and (2) the methodology can be extended to more canonical targets as well as for bistatic scattering.

description: Exploring novel strategies to manipulate the order parameter of magnetic materials by electrical means is of great importance, not only for advancing our understanding of fundamental magnetism, but also for unlocking potential practical applications. A well-established concept to date uses gate voltages to control magnetic properties, such as saturation magnetization, magnetic anisotropies, coercive field, Curie temperature and Gilbert damping, by modulating the charge carrier population within a capacitor structure1-5. Note that the induced carriers are non-spin-polarized, so the control via the electricfield is independent of the direction of the magnetization. Here, we show that the magnetocrystalline anisotropy (MCA) of ultrathin Fe films can be reversibly modified by a spin current generated in Pt by the spin Hall effect. The effect decreases with increasing Fe thickness, indicating that the origin of the modification can be traced back to the interface. Uniquely, the change in MCA due to the spin current depends not only on the polarity of the charge current but also on the direction of magnetization, i.e. the change in MCA has opposite sign when the direction of magnetization is reversed. The control of magnetism by the spin current results from the modified exchange splitting of majority- and minority-spin bands, and differs significantly from the manipulation by gate voltages via a capacitor structure, providing a functionality that was previously unavailable and could be useful in advanced spintronic devices.

description: We report on the possibility of controlling quantum random walks with a step-dependent coin. The coin is characterized by a (single) rotation angle. Considering different rotation angles, one can find diverse probability distributions for this walk including: complete localization, Gaussian and asymmetric likes. In addition, we explore the entropy of walk in two contexts; for probability density distributions over position space and walker's internal degrees of freedom space (coin space). We show that entropy of position space can decrease for a step-dependent coin with the step-number, quite in contrast to a walk with step-independent coin. For entropy of coin space, a damped oscillation is found for walk with step-independent coin while for a step-dependent coin case, the behavior of entropy depends on rotation angle. In general, we demonstrate that quantum walks with simple initiatives may exhibit a quite complex and varying behavior if step-dependent coins are applied. This provides the possibility of controlling quantum random walk with a step-dependent coin.

description: We model consumption and dividend growth as different processes across two latent regimes. We estimate the equilibrium model over 1930-2009 and show that the second regime is associated with recessions, market downturns, higher risk premia, lower consumption and dividend growth, higher volatility of returns and growth rates, and lower market-wide price-dividend ratio. The model performs better at in-sample forecasting and significantly better at out- of-sample prediction of the equity, size, and value premia and consumption and dividend growth rates and their variances than the price-dividend ratio and risk free rate do. The calibrated model replicates several features of the data.

description: The automated segmentation of cells in microscopic images is an open research problem that has important implications for studies of the developmental and cancer processes based on in vitro models. In this paper, we present the approach for segmentation of the DIC images of cultured cells using G-neighbor smoothing followed by Kauwahara filtering and local standard deviation approach for boundary detection. NIH FIJI/ImageJ tools are used to create the ground truth dataset. The results of this work indicate that detection of cell boundaries using segmentation approach even in the case of realistic measurement conditions is a challenging problem.

description: We present a unified string supergravity model based on a string-derived $SU(5)\times U(1)$ model and a string-inspired supersymmetry breaking scenario triggered by the $F$-term of the universally present dilaton field. This model can be described by three parameters: $m_t$, $\tanβ$, and $m_{\tilde g}$. We work out the predictions for all sparticle and Higgs masses and discuss the prospects for their detection at the Tevatron, LEPI,II, and HERA. We find that the cosmological neutralino relic density is always within current expectations (\ie, $Ω_χh^2_0\lsim0.9$). We also consider a more constrained version of this supersymmetry breaking scenario where the $B$-term is specified. In this case $\tanβ$ can be determined ($\tanβ\approx1.4-1.6$) and implies $m_t\lsim155\GeV$ and $m_h\lsim91\GeV$. Thus, continuing Tevatron top-quark searches and LEPI,II Higgs searches could probe this restricted scenario completely.

description: The spectral properties of Kitaev's honeycomb lattice model are investigated both analytically and numerically with the focus on the non-abelian phase of the model. After summarizing the fermionization technique which maps spins into free Majorana fermions, we evaluate the spectrum of sparse vortex configurations and derive the interaction between two vortices as a function of their separation. We consider the effect vortices can have on the fermionic spectrum as well as on the phase transition between the abelian and non-abelian phases. We explicitly demonstrate the $2^n$-fold ground state degeneracy in the presence of $2n$ well separated vortices and the lifting of the degeneracy due to their short-range interactions. The calculations are performed on an infinite lattice. In addition to the analytic treatment, a numerical study of finite size systems is performed which is in exact agreement with the theoretical considerations. The general spectral properties of the non-abelian phase are considered for various finite toroidal systems.

Teacher isolation and the inclusion of students with autism spectrum disorder: Bridging the divide
Creators: name: Coates, Mitchell
Publisher: name: Australian Catholic University
Year: 2019

description: Both researchers and clinicians have observed an apparent increase in the prevalence of Autism Spectrum Disorder (ASD) in current and upcoming student populations (Australian Bureau of Statistics, 2016; CDC, 2018). In response to these findings, the Australian Federal Government and Queensland Government have policies in place to support students in inclusive general education settings for children with ASD. The purpose of this study was to develop a more sophisticated understanding of expectations of teacher capacity to implement the inclusive practices required in Queensland educational policy, and the actual capacity of teaching staff to support their students with ASD in one school with a Special Education Program (SEP) attached. The epistemological stance adopted for this study is constructionism with the theoretical perspective interpretivism, and embedded within this perspective is symbolic interactionism. Consistent with these perspectives, case study methodology has been used where data collection, adopted to investigate the case, included document analysis, survey and semi-structured individual interviews. During the exploration phase, data were obtained from the document analysis of pre-service courses offered to teachers and teacher-aides in Queensland, Australia and an online survey of 24 participants, consisting of both teachers and teacher-aides. During the inspection phase, data were obtained from individual, semi-structured interviews with 16 of the 24 participants, comprising 12 teachers and 4 teacher-aides. This research supports previous research findings which outline a need for more ASD-specific pre-service and in-service training for teachers, however, these findings have been extended through the use of a Symbolic Interactionist lens, where five theoretical propositions have been advanced. Drawing on these theoretical propositions, the D.I.S.I Dilemma Model has been promoted as a reflection of the school environment. The findings have clear implications for departments of education and pre-service training institutions for both teachers and teacher-aides.

description: Recently, Linear Programming (LP)-based relaxations have been shown promising in boosting the performance of exact MAX-SAT solvers. We compare Semidefinite Programming (SDP) based relaxations with LP relaxations for MAX-2-SAT. We will show how SDP relaxations are surprisingly powerful, providing much tighter bounds than LP relaxations, across different constrainedness regions. SDP relaxations can also be computed very efficiently, thus quickly providing tight lower and upper bounds on the optimal solution. We also show the effectiveness of SDP relaxations in providing heuristic guidance for iterative variable setting, significantly more accurate than the guidance based on LP relaxations. SDP allows us to set up to around 80% of the variables without degrading the optimal solution, while setting a single variable based on the LP relaxation generally degrades the global optimal solution in the overconstrained area. Our results therefore show that SDP relaxations may further boost exact MAX-SAT solvers.

description: Automatic generation of natural language from images has attracted extensive attention. In this paper, we take one step further to investigate generation of poetic language (with multiple lines) to an image for automatic poetry creation. This task involves multiple challenges, including discovering poetic clues from the image (e.g., hope from green), and generating poems to satisfy both relevance to the image and poeticness in language level. To solve the above challenges, we formulate the task of poem generation into two correlated sub-tasks by multi-adversarial training via policy gradient, through which the cross-modal relevance and poetic language style can be ensured. To extract poetic clues from images, we propose to learn a deep coupled visual-poetic embedding, in which the poetic representation from objects, sentiments and scenes in an image can be jointly learned. Two discriminative networks are further introduced to guide the poem generation, including a multi-modal discriminator and a poem-style discriminator. To facilitate the research, we have released two poem datasets by human annotators with two distinct properties: 1) the first human annotated image-to-poem pair dataset (with 8,292 pairs in total), and 2) to-date the largest public English poem corpus dataset (with 92,265 different poems in total). Extensive experiments are conducted with 8K images, among which 1.5K image are randomly picked for evaluation. Both objective and subjective evaluations show the superior performances against the state-of-the-art methods for poem generation from images. Turing test carried out with over 500 human subjects, among which 30 evaluators are poetry experts, demonstrates the effectiveness of our approach.
The contribution of short-term cross-cultural immersion to the formation of Catholic school staff
Creators: name: Dutton, Monica
Publisher: name: Australian Catholic University

description: The purpose of this qualitative investigation was to explore the contribution of short-term cross-cultural immersion to the formation of Catholic school staff. The experiences of participants involved in Good Samaritan Education immersion trips served to illuminate an understanding of the immersion experience and its contribution to formation. The study aimed to discover the elements of immersion which foster transformative outcomes, and to reveal how these outcomes are evidenced in participants’ lives in the post-immersion phase. An interpretive research design using the epistemologies of constructivism and constructionism, and the theoretical perspective of symbolic interactionism underpinned the investigation. Case study methodology was adopted and data were gathered through 53 semi-structured interviews. Participants were selected based on their involvement in one of 10 Good Samaritan Education short-term cross-cultural staff immersion trips between 2004 and 2014. As the purpose of formation is transformation of individuals and communities, the data were analysed using the lenses of Transformative Learning Theory (TLT) (Mezirow, 1978a, 1978b, 2000a) and A Framework for Formation for Mission in Catholic Education (National Catholic Education Commission, 2017). These dual lenses provided appropriate scaffolds for understanding the relationships between the constructs of formation and human transformation in the context of short-term cross-cultural immersion. The findings of this research revealed that short-term cross-cultural immersion contributes to staff formation in several meaningful ways, and key elements of immersion which foster transformative outcomes were identified. As the research explored the experiences of participants from nine schools involved in 10 immersion trips to one of five host communities over a 10-year period, the ongoing nature of the influence of immersion was evidenced over various timeframes. Outcomes triggered by their immersion experience were noted in all aspects of participants’ lives. The investigation is significant as it addressed a previously unresearched avenue for formation of Australian Catholic school staff, and based on the findings, offers a development of Mezirow’s (1978a, 1978b, 2000a) model of Transformative Learning Theory. The research concludes that short-term cross-cultural immersion trips make a significant contribution to the formation of Catholic school staff. The findings reveal critical elements in the design and facilitation of immersion trips, the importance of points of connection for participants and the pivotal nature of the medium-term timeframe in the post-immersion phase. The research has the capacity to assist school and system leaders to design immersion experiences which contribute to the formation of Catholic school staff, thereby complementing strategic plans for the mission life of their schools.
