description: We examine the possibility that pertinent impurities in a condensed matter system may help in designing quantum devices with enhanced coherent behaviors. For this purpose, we analyze a field theory model describing Y- shaped superconducting Josephson networks. We show that a new finite coupling stable infrared fixed point emerges in its phase diagram; we then explicitly evidence that, when engineered to operate near by this new fixed point, Y-shaped networks support two-level quantum systems, for which the entanglement with the environment is frustrated. We briefly address the potential relevance of this result for engineering finite-size superconducting devices with enhanced quantum coherence. Our approach uses boundary conformal field theory since it naturally allows for a field-theoretical treatment of the phase slips (instantons), describing the quantum tunneling between degenerate levels.

description: Blood was collected from 684 healthy volunteers and examined for total and differential white blood cell (WBC) counts. A subgroup also was tested for numbers of T cells, B cells, and CD4 and CD8 subsets. Smoking status and alcohol consumption were determined by means of questionnaire, and smoking status was verified with serum cotinine concentration. High smoking rate was associated with increases in all counts. Former smokers abstinent less than 5 years still demonstrated elevated counts, whereas those abstinent more than 5 years had WBC counts comparable to those in persons who were never smokers. Compared with levels in those who had never smoked, total WBC counts were 27% higher in current smokers and 14% higher in former smokers who were abstinent for less than 5 years. Lymphocyte counts were 9% higher in those consuming more than one alcoholic drink per day than in those consuming less alcohol, but drinking was not associated with other cell populations.

description: L’Evaluation des Besoins Financiers (EBF) de la Biodiversité a pour but de faire une estimation complète des ressources financières nécessaire pour atteindre les objectifs nationaux en matière de biodiversité. Ces objectifs sont ici basés sur la Stratégie et plan d’action national de la biodiversité (SPANB) et plus précisément sur la période restante de la SPANB qui s’étale de 2022 à 2025. La SPANB est composée de 05 axes stratégiques et 20 Objectifs.

Pour réaliser cette EBF, BIOFIN Madagascar a procédé, grâce au recrutement d’une équipe spécifique, à l’élaboration d’un cadre logique de la SPANB en y classant les activités proposées par différentes parties prenantes (secteur public, privé et les ONG). Chaque activité a été détaillée et, une ou des cible(s) et les acteurs clés ont été identifiés. Plus de 500 activités ont été recensées lors de la collecte des données effectuée par l’équipe consultante de ce cadre logique SPANB.

S’ensuivit l’estimation des coûts que représenterait la mise en œuvre de ces activités, la budgétisation des activités par la détermination du coût unitaire a été conduite en suivant les instructions du Manuel BIOFIN 2018. Suite à cela, il a été possible d’ estimer les besoins de financement pour la conservation de la biodiversité de Madagascar à 3 598 985 318 458 Ar soit à 899 746 330 USD pour la période 2022-2025. Outre le besoin de financement très important, il a également été identifié que les activités sur le reboisement et la restauration et la gestion des aires protégées occupent la majeure partie des coûts de réalisation de la SPANB.

description: Objective: This study examined a conceptual model of resilience and sense of belonging as mediators in the association between positivity and generalized anxiety among underrepresented college students. Sample: Undergraduate students (N = 447; 18.6% White, 18.1% Black, 39.6% Hispanic, 20.4% Asian, 3.4% Other; M [subscript age] = 19.06 years; 62% female) completed an online Health & Well-Being survey. Methods: Controlling for age, sex, race/ethnicity, first-generation status, and living status, the proposed conceptual model was examined using path analysis in Mplus. Results: Positivity was negatively associated with anxiety directly (ƅ = -.435, p .05). Although positivity was significantly associated with sense of belonging (ƅ = .611, p .05). Conclusions: Results indicate that resilience partially mediates, or accounts for, the association between positivity and anxiety, whereas sense of belonging does not. This study warrants future investigation into the potentially beneficial role of positivity and resilience resources in reducing anxiety for underrepresented college students.

description: Accurately predicting and inferring a driver's decision to brake is critical for designing warning systems and avoiding collisions. In this paper we focus on predicting a driver's intent to brake in car-following scenarios from a perception-decision-action perspective according to his/her driving history. A learning-based inference method, using onboard data from CAN-Bus, radar and cameras as explanatory variables, is introduced to infer drivers' braking decisions by combining a Gaussian mixture model (GMM) with a hidden Markov model (HMM). The GMM is used to model stochastic relationships among variables, while the HMM is applied to infer drivers' braking actions based on the GMM. Real-case driving data from 49 drivers (more than three years' driving data per driver on average) have been collected from the University of Michigan Safety Pilot Model Deployment database. We compare the GMM-HMM method to a support vector machine (SVM) method and an SVM-Bayesian filtering method. The experimental results are evaluated by employing three performance metrics: accuracy, sensitivity, specificity. The comparison results show that the GMM-HMM obtains the best performance, with an accuracy of 90%, sensitivity of 84%, and specificity of 97%. Thus, we believe that this method has great potential for real-world active safety systems.

description: Scalar cosmological perturbations with nearly flat power spectrum may originate from perturbations of the phase of a scalar field conformally coupled to gravity and rolling down negative quartic potential. We consider a version of this scenario whose specific property is a long intermediate stage between the end of conformal rolling and horizon exit of the phase perturbations. Such a stage is natural, e.g., in cosmologies with ekpyrosis or genesis. Its existence results in small negative scalar tilt, statistical anisotropy of all even multipoles starting from quardupole of general structure (in contrast to the usually discussed single quadrupole of special type) and non-Gaussianity of a peculiar form.

Nature of the superconductor-insulator transition in disordered superconductors

description: As a superconducting thin film becomes disordered and subject to an increasing magnetic field, a point is reached when it undergoes a transition from a superconducting to an insulating state. We use the Bogoliubov-De-Gennes equations and a novel Monte-Carlo approach to study this transition numerically, starting from a microscopic hamiltonian. The key effect of disorder is to create 'islands' of strong superconductivity, coupled by regions that are only weakly superconducting. In the case of weak disorder, an increasing magnetic field eventually destroys the superconducting state throughout the material, leading to an insulator. On the other hand, when disorder is strong, superconductivity persists in the islands, and the effect of a magnetic field is to suppress the coupling between them, resulting in strong superconducting phase fluctuations, again leading to an insulating state. These findings may be relevant to the high-temperature superconductors, where intrinsic disorder may play a role.

description: Applied health research, distinct from fundamental biomedical research, encompasses scientific exploration and a societal mission, emphasizing relevance to healthcare systems. Applied health services research specifically applies research methods to address real-world healthcare delivery, management, and policy issues, aiming to generate evidence-based solutions for improving quality, effectiveness, and accessibility. This type of research often involves collaboration among researchers, healthcare providers, and policymakers, utilizing various methods such as randomized controlled trials, observational studies, and qualitative research. The findings contribute to informed decisionmaking, guiding policy development and practices to enhance population health. The Contextualized Health Research Synthesis Program (CHRSP), introduced by the Newfoundland and Labrador Center for Applied Health Research (NLCAHR), is a vital initiative addressing the knowledge-to-action (KTA) gap with tailored evidence for Newfoundland and Labrador (NL). As the program surpasses its 15th year, assessing its impact, strengthening its mandate, and sharing lessons with other jurisdictions facing similar challenges is necessary. The thesis aims to document key lessons from CHRSP, identifying pathways for increased impact. By evaluating the program's processes and impact through interviews with past and current clients, it seeks to provide insights for future improvements. Some key findings highlighted the importance of contextualizing research evidence to improve healthcare outcomes, the role of CHRSP in decision-making, and the benefits of engagement in the research process. The study also identified barriers to change that must be addressed to improve healthcare outcomes in NL.

description: This study investigated the possibility that the previously mixed findings relating to cognitive deficits in Parkinson's disease might be attributable to inhomogeneity within the patients sampled, with attentional deficits occurring only for those Parkinson's patients who also have additional frontal lobe impairment. Twentyfive patients with idiopathic Parkinson's disease were classified as showing frontal dysfunction, or not, on the basis of their performance on the Wisconsin Card Sorting Test and the picture arrangement subtest of the WAIS. The two groups, and a control group of normal elderly subjects matched for age and IQ, undertook tests of visual attention designed to dissociate baseline response speed from central information processing speed. Error rates did not differ between the groups. Performance of the non-frontally impaired Parkinson's group was indistinguishable from that of the controls[ By contrast, the 'frontally impaired' Parkinson's group responded significantly more slowly than the controls. Further analyses indicated that for the frontally-impaired Parkinson's group, information processing and automatic functions were unimpaired but there was a generalised slowing (as reflected by increased baseline response time) which may represent a non-specific global cognitive impairment. These findings suggest that the frontal lobes may be implicated in slowed response speed in Parkinson's disease.Elsevier Science Ltd[ All rights reserved[

description: The decay of the K+K- hadronic atom kaonium is investigated non-perturbatively using meson-meson interaction amplitudes taken from leading order chiral perturbation theory in an approach adapted from that proposed by Oller and Oset [18]. The Kudryavtsev-Popov eigenvalue equation is solved numerically for the energy shift and decay width due to strong interactions in the 1s state. These calculations introduce a cutoff ~ 1.4 GeV in O(4) momentum space that is necessary to regulate divergent loop contributions to the meson-meson scattering amplitudes in the strong-interaction sector. One finds lifetimes of 2.2 \pm 0.9 x 10-18s for the ground state of kaonium.

description: We tested the relationship of objectively measured sleep quantity and quality with positive characteristics of the child. Sleep duration, sleep latency and sleep efficiency were measured by an actigraph for an average of seven (range = 3-14) consecutive nights in 291 8-year-old children (standard deviation = 0.3 years). Children's optimism, self-esteem and social competence were rated by parents and/or teachers. Sleep duration showed a non-linear, reverse J-shaped relationship with optimism (P = 0.02), such that children with sleep duration in the middle of the distribution scored higher in optimism compared with children who slept relatively little. Shorter sleep latency was related to higher optimism (P = 0.01). The associations remained when adjusting for child's age, sex, body mass index, and parental level of education and optimism. In conclusion, sufficient sleep quantity and good sleep quality are related to children's positive characteristics. Our findings may inform why sleep quantity and quality and positive characteristics are associated with wellbeing in children.

A set of solutions of the Dirac-type equation in the 5-dimensional Galilean space-time is obtained, based on the Pauli representation of $8\times 8$ gamma matrices. In order to find an explicit solution, we diagonalize the Klein-Gordon divisor by using the Galilean boost.

description: BACKGROUND: Sleep quality is thought to be an important predictor of immunity and, in turn, susceptibility to the common cold. This article examines whether sleep duration and efficiency in the weeks preceding viral exposure are associated with cold susceptibility. METHODS: A total of 153 healthy men and women (age range, 21-55 years) volunteered to participate in the study. For 14 consecutive days, they reported their sleep duration and sleep efficiency (percentage of time in bed actually asleep) for the previous night and whether they felt rested. Average scores for each sleep variable were calculated over the 14-day baseline. Subsequently, participants were quarantined, administered nasal drops containing a rhinovirus, and monitored for the development of a clinical cold (infection in the presence of objective signs of illness) on the day before and for 5 days after exposure. RESULTS: There was a graded association with average sleep duration: participants with less than 7 hours of sleep were 2.94 times (95% confidence interval [CI], 1.18-7.30) more likely to develop a cold than those with 8 hours or more of sleep. The association with sleep efficiency was also graded: participants with less than 92% efficiency were 5.50 times (95% CI, 2.08-14.48) more likely to develop a cold than those with 98% or more efficiency. These relationships could not be explained by differences in prechallenge virus-specific antibody titers, demographics, season of the year, body mass, socioeconomic status, psychological variables, or health practices. The percentage of days feeling rested was not associated with colds. CONCLUSION: Poorer sleep efficiency and shorter sleep duration in the weeks preceding exposure to a rhinovirus were associated with lower resistance to illness.

description: Study Objectives: Experimental evidence links poor sleep with susceptibility to infectious illness; however, it remains to be determined if naturally occurring sleep is associated with immune responses known to play a role in protection against infection. The aim of this study was to determine whether sleep duration, sleep efficiency, and sleep quality, assessed in the natural environment, predict magnitude of antibody responses to a novel antigen among community volunteers in midlife. Design: Observational. Measurements and Results: Healthy midlife adults (n = 125; 70 female; age 40-60 yr) received the standard 3-dose hepatitis B vaccination series. Actigraphy and electronic sleep diaries were used to assess sleep duration, sleep efficiency, and subjective sleep quality. Viral-specific antibody titers were obtained prior to the 2nd and 3rd vaccination to assess primary and secondary antibody responses. Clinical protection status (anti-hepatitis B surface antigen immunoglobulin G ≥ 10 mIU/ml) was assessed 6 mo after the final immunization. Regression analyses revealed that shorter actigraphy-based sleep duration was associated with a lower secondary antibody response independent of age, sex, body mass index, and response to the initial immunization. Shorter sleep duration, measured by actigraphy and sleep diary, also predicted a decreased likelihood of being clinically protected from hepatitis B at the conclusion of the vaccination series. Neither sleep efficiency nor subjective sleep quality were significant predictors of antibody response. Conclusions: Short sleep duration in the natural environment may negatively affect in vivo antibody responses to novel antigens, providing a possible explanation for observed associations of poor sleep with increased susceptibility to infectious disease.

description: Using extensive computer simulations, the behavior of the structural modes --- more precisely, the eigenmodes of a phantom Rouse polymer --- are characterized for a polymer in the three-dimensional repton model, and are used to study the polymer's dynamics at time scales well before the tube renewal. Although these modes are not the eigenmodes for a polymer in the repton model, we show that numerically the modes maintain a high degree of statistical independence. The correlations in the mode amplitudes decay exponentially with $(p/N)^2A(t)$, in which $p$ is the mode number, $N$ is the polymer length and $A(t)$ is a single function shared by all modes. In time, the quantity $A(t)$ causes an exponential decay for the mode amplitude correlation functions for times $<1$; a stretched exponential with an exponent 1/2 between times 1 and $τ_R\sim N^2$, the time-scale for diffusion of tagged reptons along the contour of the polymer; and again an exponential decay for times $t>τ_R$. Having assumed statistical independence and the validity of a single function $A(t)$ for all modes, we compute the temporal behavior of three structural quantities: the vectorial distance between the positions of the middle monomer and the center-of-mass, the end-to-end vector, and the vector connecting two nearby reptons around the middle of the polymer. Furthermore, we study the mean-squared displacement of the center-of-mass and the middle repton, and their relation with the temporal behavior of the modes.

This allows us to discuss the discrete symmetries in the Galilean space-time, which is embedded in the (5+1) Minkowski space-time. We discuss the Dirac-type field, for which we give the 8\times 8 gamma matrices explicitly. We demonstrate that the CPT theorem holds in the (5+1) Galilean space-time.

description: The propagation of guided electromagnetic waves in open elliptical metamaterial waveguide structures is investigated. The waveguide contains a negative-index media core, where the permittivity, $ε$ and permeability $μ$ are negative over a given bandwidth. The allowed mode spectrum for these structures is numerically calculated by solving a dispersion relation that is expressed in terms of Mathieu functions. By probing certain regions of parameter space, we find the possibility exists to have extremely localized waves that transmit along the surface of the waveguide.

description: The 1(0)-0(1) transition of SO at 30 GHz has been observed in several sources, including the first detection of sulfur monoxide in cold dark clouds without apparent internal energy sources. The SO transition appears to be an excellent tracer of structure in dark clouds, and the data support suggestions that self-absorption is important in determining emission profiles in such regions for large line-strength transitions. Column densities estimated from a comparison of the results for the two isotopic species indicate a high fractional abundance of SO in dark clouds.

description: The numerical renormalization group (NRG) is rephrased as a variational method with the cost function given by the sum of all the energies of the effective low-energy Hamiltonian. This allows to systematically improve the spectrum obtained by NRG through sweeping. The ensuing algorithm has a lot of similarities to the density matrix renormalization group (DMRG) when targeting many states, and this synergy of NRG and DMRG combines the best of both worlds and extends their applicability. We illustrate this approach with simulations of a quantum spin chain and a single impurity Anderson model (SIAM) where the accuracy of the effective eigenstates is greatly enhanced as compared to the NRG, especially in the transition to the continuum limit.

description: Although object perception involves encoding a wide variety of object properties (e.g., size, color, viewpoint), some properties are irrelevant for identifying the object. The key to successful object recognition is having an internal representation of the object identity that is insensitive to these properties while accurately representing important diagnostic features. Behavioral evidence indicates that the formation of these kinds of invariant object representations takes many years to develop. However, little research has investigated the developmental emergence of invariant object representations in the ventral visual processing stream, particularly in the lateral occipital complex (LOC) that is implicated in object processing in adults. Here, we used an fMR adaptation paradigm to evaluate age-related changes in the neural representation of objects within LOC across variations in size and viewpoint from childhood through early adulthood. We found a dissociation between the neural encoding of object size and object viewpoint within LOC: by age of 5-10 years, area LOC demonstrates adaptation across changes in size, but not viewpoint, suggesting that LOC responses are invariant to size variations, but that adaptation across changes in view is observed in LOC much later in development. Furthermore, activation in LOC was correlated with behavioral indicators of view invariance across the entire sample, such that greater adaptation was correlated with better recognition of objects across changes in viewpoint. We did not observe similar developmental differences within early visual cortex. These results indicate that LOC acquires the capacity to compute invariance specific to different sources of information at different time points over the course of development.

description: We present a new method for generating initial conditions for numerical cosmological simulations in which massive neutrinos are treated as an extra set of N-body (collisionless) particles. It allows us to accurately follow the density field for both Cold Dark Matter (CDM) and neutrinos at both high and low redshifts. At high redshifts, the new method is able to reduce the shot noise in the neutrino power spectrum by a factor of more than $10^7$ compared to previous methods, where the power spectrum was dominated by shot noise at all scales. We find that our new approach also helps to reduce the noise on the total matter power spectrum on large scales, whereas on small scales the results agree with previous simulations. Our new method also allows for a systematic study of clustering of the low velocity tail of the distribution function of neutrinos. This method also allows for the study of the evolution of the overall velocity distribution as a function of the environment determined by the CDM field.

Subjects: Cement, Compressive strength, Lime, Elevated Temperature, Muffle Furnace Pumice powder, Workability.

description: Concrete materials in structures are usually exposed to high temperatures during fire.
 Knowing the relative properties of concrete after such an exposure of fire on concrete is
 great importance in terms of the serviceability of buildings. This research primarily deals
 with the characteristics of concrete, including compressive strength and workability.
 Moreover, this research also investigates the thermal stability of concrete mixes at elevated
 temperature. Twenty five mixes of concrete were prepared at different replacement levels of
 lime (0%, 5%, 10%, 15% & 20%) and pumice powder (0%, 10%, 20%, 30% & 40%) with
 cement. The water/cement ratio in all mixes was kept at 0.55. The workability of concrete was
 tested immediately after preparing the concrete mix whereas the compressive strength of
 concrete was tested after 7, 14 and 28 days of curing in water. The effect of elevated
 temperatures on compressive strength of the concrete cubes were tested at temperatures
 range of 1500C,3000C,and 6000and the concrete cubes were cured for 2 hours in Muffle
 Furnace and allowed to cool down for 12 hours before compressive strength test was
 conducted. Based on the test results, a combination of 10% lime and 10% pumice powder is
 recommended with 10.41 % reduction of cost. And the compressive strength of concrete was
 reduced for all combination of lime and pumice powder at elevated Temperature.

description: Il lavoro rappresenta un elemento cruciale per l’integrazione sociale e la valorizzazione delle persone migranti, ma spesso è segnato da dinamiche di esclusione e sfruttamento che ne minano la dignità. La pedagogia del lavoro, con il suo approccio inclusivo e formativo, è chiamata a promuovere percorsi educativi capaci di valorizzare le competenze e i diritti dei lavoratori stranieri. Questo implica la costruzione di luoghi lavorativi – non solo fisici – che rispettino le diversità culturali e il riconoscimento della persona come centro dell’agire professionale. Necessario, dunque, ripensare in toto l’approccio alle questioni, costruendo le condizioni per trasformare il lavoro in un luogo di coesione sociale e di emancipazione, valorizzando la dignità umana, le relazioni educative e il senso di comunità.


 

Work represents a crucial element for the social integration and empowerment of migrants but is often marked by dynamics of exclusion and exploitation that undermine their dignity. The pedagogy of work, with its inclusive and formative approach, is called upon to promote educational pathways capable of enhancing the skills and rights of foreign workers. This requires the construction of workplaces - both physical and metaphorical - that respect cultural diversity and recognize the person as the center of professional action. It is therefore necessary to entirely rethink the approach to these issues, creating conditions to transform work into a space for social cohesion and emancipation, while valuing human dignity, educational relationships and a sense of community.

Critical community development: a comparative case study of nonprofit urban agriculture organizations
Creators: name: Tarng, Danny
Publisher: name: No Publisher Supplied

description: Many nonprofit urban agriculture organizations (NUAOs) frame their community food work as food justice and food sovereignty in an attempt to pursue transformative social change. Inherent to these frameworks is the insistence upon food as a human right and democratic control of the food system. The pursuit of these ideals, unfortunately, has left much to be desired, in great part due to the ever-constraining neoliberal context in which NUAOs and must operate. Despite this, there is much community food work can learn from critical community development- a discourse and practice that seeks to reclaim and harness the emancipatory potential of community development.For this dissertation, I conducted several months of participant-observation and dozens of in-depth interviews in two cities with robust urban agriculture movements- Detroit, MI and Oakland, CA. From this fieldwork, I present multiple case studies through which I interface critical community development with community food work. I establish a critical community development framework pillared by critical education and community control, both of which serve as meaningful touchstones for unambiguous visions of food justice and food sovereignty. Through these lenses, I am able to analyze NUAOs, their work, and the political, economic, social contexts in which they operate. Furthermore, this dual-lens framework provides a set of criteria that researchers, policymakers, and practitioners can use to analyze and reflect upon discourse, policies, practices, and institutions in order to guide or re-orient community development work towards transformational social change.While there are a few good examples of NUAOs pursuing such change, the case studies here suggest a strong dissonance between the trajectory of the community food work being performed and the radical political analysis that undergird food justice and food sovereignty. For one, engaging in the praxis that critical education demands runs counter to the professionalized nonprofit social service approach that NUAOs have widely adopted. A community control lens reveals other tensions, such as the difficulties of achieving land tenure and sustaining community in the midst of gentrification and social displacement. At the same time, realistic and meaningful opportunities exist to create pathways and institutions that will expand a community’s power to self-determine local food systems.

description: We present one year of optical and near-infrared photometry and spectroscopy of the Type IIP SNe 2013K and 2013am. Both objects are affected by significant extinction, due to their location in dusty regions of their respective host galaxies, ESO 009-10 and NGC 3623 (M65). From the photospheric to nebular phases, these objects display spectra congruent with those of underluminous Type IIP SNe (i.e. the archetypal SNe 1997D or 2005cs), showing low photospheric velocities (~2 X 10**3 km/s at 50d) together with features arising from Ba II which are particularly prominent in faint SNe IIP. The peak V-band magnitudes of SN 2013K (-15.6 mag) and SN 2013am (-16.2 mag) are fainter than standard-luminosity Type IIP SNe. The ejected Nickel masses are 0.012+-0.010 and 0.015+-0.006 Msol for SN 2013K and SN 2013am, respectively. The physical properties of the progenitors at the time of explosion are derived through hydrodynamical modelling. Fitting the bolometric curves, the expansion velocity and the temperature evolution, we infer total ejected masses of 12 and 11.5 Msol, pre-SN radii of ~460 and ~360 Rsol, and explosion energies of 0.34 foe and 0.40 foe for SN 2013K and SN 2013am. Late time spectra are used to estimate the progenitor masses from the strength of nebular emission lines, which turn out to be consistent with red supergiant progenitors of ~15 Msol. For both SNe, a low-energy explosion of a moderate-mass red supergiant star is therefore the favoured scenario.

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.
