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.

Subjects: subject: Computer Science.

description: In this thesis, we discuss an important issue in computational linguistics: distinguishing between formal and informal style of texts, in document classification and in text generation. There is a need to identify formal texts and informal texts automatically. In addition, there is a need of having a computer system that could generate correct English texts in formal or informal style. Therefore, we propose to use two main techniques in order to solve the two tasks. The first technique is to build a model that can be used to classify any text or sentence as having formal or informal style. The second technique is based on natural language generation (NLG) and it generates correct English sentences with formal or informal style. In order to achieve our goals, we start by studying the main differences between formal and informal style and summarize their characteristics. In addition, we manually collect parallel lists of formal versus informal words, phrases, and expressions from different sources that will be used for our proposed work. Then, we build our model for the classification task by using machine learning technique in order to classify texts and sentences into formal and informal style. The evaluation results show that our model is able to predict a class of formal/informal for any text or sentence with high accuracy. After that, we build our system that can generate formal and informal sentences by using NLG techniques. The evaluation results on a sample of generated sentences show that our NLG system can produce high-quality sentences in formal or informal style. The main contribution of this work consists in designing a set of features that led to good results for both tasks: text classification and text generation with different formality levels.
Mechanisms of resistance to anti-thymidylate synthase (TS) chemotherapeutic agents in colon cancer

description: Thymidylate Synthase (TS) catalyzes the final step in the synthesis of thymidylate, a nucleotide required for DNA synthesis. This enzyme is the target enzyme for several important anti-cancer drugs including 5-fluorouracil (5-FU) and 5-fluorodeoxyuridine (5-FUdR). 5-FU and 5-FUdR are metabolized to FdUMP which, in the presence of a folate cofactor, inhibits TS by forming a tight covalent "ternary complex". TS is usually considered to be a cytoplasmic enzyme, but some reports suggest it may also be present in the nucleus. One recent report has indicated that high levels of nuclear TS were associated with poorer clinical response to 5-FU. Using a combination of immunocytochemistry, confocal microscopy, immunohistochemistry, western blotting and cell fractionation techniques, evidence is presented that a fraction of cellular TS is indeed located in the nucleus of some colorectal cancer cell lines and tissues. The specificity for TS of the polyclonal antibody used was first confirmed. The effect of TS overexpression on cellular localization was studied in HeLa-55 cells, a 5-FUdR-resistant line containing an amplified TS gene. Nuclear TS was clearly evident in HeLa-55 but not in parental HeLa cells. Fractionation of HeLa-55 growing in 5-FUdR showed that both the ternary complex and free TS were present in the cytoplasm, while only free TS was present in the nucleus. From a panel of 6 colorectal cancer lines and normal fibroblasts, RKO and HCT-116 clearly showed nuclear TS. Strong evidence of nuclear TS in some colorectal cancer tissues is also presented. A putative leucine-rich nuclear export signal sequence (NES) was identified in TS protein. TS constructs lacking this sequence accumulated more nuclear TS, but the sequence did not function as a nuclear export signal when fused to GFP. A recent report suggests that p53 status can affect the sensitivity of HCT-116 to 5-FUdR. I examined HCT-116 p53 wt and HCT-116 p53 null cells and observed that p53 null cells, in contrast to p53 wt cells, failed to form a ternary complex when exposed to 5-FUdR. p53 wt cells were also more sensitive to killing by 5-FUdR. However, the differences observed were in fact independent of p53 status. 5-FUdR-sensitive cell lines became resistant after several passages in culture. Current evidence suggests that the basis of resistance is related to either drug metabolism or uptake. This thesis has contributed towards a better understanding of TS, a cellular target for an important class of anti-cancer drugs.

description: The ethnobotany of East Timor was examined for the first time with emphasis being placed on documenting traditional knowledge of medicinal plants. The medicinal plant traditions of 3 distinct East Timorese cultures were studied and compared using both modern quantitative ethnobotanical methods but also with classical descriptive ethnobotanical techniques. A total of 116 medicinal plant species were identified. The medicinal plant traditions of the Laklei and Idate cultures of East Timor were compared using Trotter and Logan's (1986) quantitative 'informant consensus factor'. On average, informant consensus was greater in Laklei suggesting a medicinal plant tradition that is more well defined than in Idate, where informants are more likely to use the same medicinal plants when treating similar illnesses. Furthermore, only 11 of 86 medicinal plant species documented with these two cultures were used by both cultures of which only 6 had similar uses. The medicinal plant tradition of a third indigenous culture, the Fataluku people, was documented using classical descriptive ethnobotanical techniques. Over 70% of the Fataluku medicinal plants were different from those used by the Laklei or the Idate people. (Abstract shortened by UMI.)

Representation and identity: A study of the Brussels 228 chansonnier and patronage in Margaret of Austria's court
Creators: name: Lamarre, Catherine
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Music.

description: This study examines the sixteenth century chansonnier, Brussels 228, which was compiled for Margaret of Austria (1480-1530). The analysis of the text, music, and gendered discourse found within will reveal how Margaret's status as a widow and a ruler influenced her musical patronage and the construction of this manuscript. In particular, the chansons Me fauldra il, Il me fait mal, and the two settings of Dulces exuvie will reveal the involvement of Margaret within the artistic production of her court. As well, an analysis of texts set to music within this chansonnier as well as by Josquin des Prez will examine the nature of his relationship with members of Margaret's court. The analysis of these works supports the underlying premise of this thesis, that Margaret manipulated the image of herself as widow along with existing societal conventions to produce a document that is an ideal expression of Margaret's patronage and her self.
Policy-driven access control for mobile environments

description: SOA (Service Oriented Architecture) enables interoperability between heterogeneous systems or domains. By complying with proper SOA specifications that are usually XML based, a service provider can provide service to any group of service consumers. A service consumer or requester can ask for a service from any service providers that satisfy its service criteria without knowing any implementation specifications that the service providers adopt. However, a transaction or a set of message exchanges between mutually interactive parties cannot be realized prior to the establishment of a trusted relationship that is embodied in granting or denying access to certain resources under the governance of any involved party. This thesis proposes XACML-based, policy-driven, access-control architecture and a key exchange/authentication framework/protocol at layer 7. The thesis examines a number of authorization and secure-channel establishment issues found not only in a normal service requester-provider environment, but also in an environment that involves mobile requesters. The proposal is derived from a careful study of authorization request/decision rendering procedures in a number of realistic business and leisure scenarios. The scenarios are characterized mainly by (a) the distribution of access control; (b) the indeterminacy of the access control model that is implemented; (c) the distributed storage of policies/organization guidelines/regional laws; (d) the lack of common representations of basic access-control elements such as subject (principle) IDs/resource IDs; and (e) the need to establish secure communication channels over unsecured public networks between security domains. In order to solve these problems, some novel concepts are raised, such as (a) a subject ID mapping service; (b) meta policy server (MPS); (c) reverse authorization; and (d) private reputation server. Furthermore, a peer-to-peer security handshake protocol infrastructure (KEAML/KEAML-KE) at layer 7 and its implementation are presented. Key words.

Predispositional and situational processes underlying choking under pressure: An application of the Self-Determination Theory
Creators: name: Davis, Hannah
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Psychology, Clinical.

description: The purpose of this dissertation was to use a multidimensional approach to explain choking, via an incorporation of dispositional and situational variables to expand on Baumeister and Showers' (1986) initial conceptualization of choking. This objective was achieved through a series of four studies using the Self-Determination Theory (SDT). In Study 1 (n = 268) we created a taxonomy of pressure contexts using an online survey. Autonomous sport motivation predicted a positive perception of performance under pressure. Study 2 (n = 138) consisted of a laboratory experiment using a 2 (high vs. low motivation) x 2 (self-awareness manipulation) by 3 (performance on basketball arcade game trials) mixed-factorial design. Results revealed that as pressure to perform increased, performance decreased. Participants in the self-awareness condition performed significantly worse than their counterparts. We unexpectedly found that high self-determined participants performed significantly worse across ail three trials compared to low self-determined participants. Study 3 (n = 34) was conducted with swimmers competing at the Canadian Olympic Trials. We found significant relationships between sport motivation and performance whereby autonomous sport motivation was negatively associated with performance decrements in participants' most important events. Study 4 (n = 40) consisted of an online survey with athletes to explore quantitative and qualitative differences between perceived best and worst performances using a within-participant design. In line with SDT, in descriptions of their best performances, participants reported focusing on the task itself, being less distracted, and simply enjoying what they were doing. In contrast, participants' emphases were on being distracted by their environmentlothers, too much/not enough motivation, and lacking confidence/increased anxiety in descriptions of their worst performances. Overall, this program of research extends the original criteria of choking using SDT. Results emphasize the importance of studying skilled athletes and provide insight into the situational variables that increase pressure (e.g., self-awareness, goals, focus). Future research should focus on further developing an integrated model of choking using SDT as a theoretical framework with skilled athletes evaluated over time in order to determine specific dispositional and situational variables that increase the likelihood of choking under pressure.

description: As Large Language Models (LLMs) rise in popularity, it is necessary to assess their capability in critically relevant domains. We present a comprehensive evaluation framework, grounded in science communication research, to assess LLM responses to questions about climate change. Our framework emphasizes both presentational and epistemological adequacy, offering a fine-grained analysis of LLM generations spanning 8 dimensions and 30 issues. Our evaluation task is a real-world example of a growing number of challenging problems where AI can complement and lift human performance. We introduce a novel protocol for scalable oversight that relies on AI Assistance and raters with relevant education. We evaluate several recent LLMs on a set of diverse climate questions. Our results point to a significant gap between surface and epistemological qualities of LLMs in the realm of climate communication.

description: This paper presents a groundbreaking extension of the Light-Pi Connection framework to the realm of black holes. By treating black holes as resonance states within a recursive vacuum architecture defined by π, φ (the golden ratio), and the speed of light, this work offers a full resolution of the singularity, information, and firewall paradoxes—without requiring modifications to general relativity or quantum mechanics.

The theory derives:

Exact black hole mass and structure from shell resonance (e.g., Gaia BH1 at Shell N₀ + 212),

Complete Hawking temperature formulas with quantum corrections,

A resonance-based encoding system that preserves information,

A nested interior structure eliminating singularities through φ-scaling,

Predictive formulas for gravitational wave spectra, wormhole formation, and black hole evaporation.

Fully supported by Python code and derivations from first principles, the paper replaces the notion of “mystery” in black hole physics with mathematical precision, showing that black holes are not anomalies but perfect expressions of a recursive universal pattern.

description: La mondialisation, la complexification des relations politiques nationales et internationales ainsi que l'émergence de sphères décisionnelles extraétatiques semblent miner la capacité d'action politique de l'État. Peu à peu se perd la capacité instituante de l'État qui est substituée par une logique réactive et gestionnaire. Au coeur de ce processus de transformation de la politique gouvernementale, on doit reconnaître l'apport des médias et des nouvelles technologies de l'information et des communications (NTIC). Secondes par des technologies de plus en plus performantes, les médias sont d'une importance grandissante en politique de par leur capacité de légitimation des acteurs politiques. C'est dans cette perspective donc que nous estimons que le succès politique dépend du succès et de l'image médiatique. Une question fondamentale traverse notre étude: l'État peut-il toujours être porteur de changement et d'innovation politique, et ce, malgré les lacunes du système médiatico-politique en place?
The influence of wetting and drying cycles on the biogeochemical dynamics of mercury in sediments

Year: 2005
Subjects: subject: Biogeochemistry.
subject: Environmental Sciences.

description: Decommissioning hydro-dams increases sediment exposure to air, altering biogeochemical cycling of metals. Hg and MeHg mobility was studied in reservoir sediments from two Eastern Ontario lakes (Stump (SL) and Black Donald (BDL)) submitted to wet/dry cycles with artificial rainwater (pH∼4.5) every two weeks. Leachate pH, sulphate, sulphide and MeHg, and sulphate-reducing bacteria (SRB) populations were monitored over 6 months. The sediments did buffer the rainwater at the start of the experiment, but leachate pH decreased over time for both lakes. MeHg release occurred during the first draining event (2-4 ppt), and decreased thereafter, with no relationship with pH, sulphide and sulphate. SRB populations remained constant over time. Over 70% of Hg was in the non-labile refractory organic and residual phases, where Hg moved to semi-mobile phases in SL, but shifted to more immobile phases in BDL over time. Decommissioning hydro-dam reservoirs may increase acid production and alter Hg partitioning in sediments, while MeHg release will be low.
Networks among injection drug users: Random or scale-free?

Year: 2007
Subjects: subject: Health Sciences, Epidemiology.

description: The primary goal of this research was to identify whether the structure of the network of individuals who inject drugs and share drug injection equipment in Winnipeg, Canada may be scale-free. Recently, sexual networks have been found to be scale-free in a wide range of populations which has important implications in terms of the spread of disease. Epidemic thresholds do not exist in a scale-free network and as a result even weakly infectious viruses can spread easily through a network of contacts. By analogy, identifying the structure of contacts formed by individuals in other infectious disease networks may also help to define transmission dynamics which can be used to develop more effective interventions. In a series of three papers the scientific literature from a variety of disciplines including physics, epidemiology, mathematical, biological and computer sciences relating to scale free networks is reviewed and integrated; methods used to identify scale-free networks are tested and compared among individuals who inject drugs in Winnipeg, Canada using data from two network studies (a pilot study and a main study); and potential new interventions that could be implemented to help reduce the transmission of HIV and HCV among individuals who inject drugs by the existing needle exchange program are recommended based on the results.

Influence of the potency of antigen presentation on CD8+ T cell differentiation and memory

description: CD8+ T cells curtail the proliferation of intracellular pathogens. However, the influence of the potency of stimulation on the development of CD8+ T cell memory is not clear. Using recombinant Ovalbumin (OVA) expressing intracellular bacteria, Mycobacterium bovis (BCG) which induces muted T cell activation, and Listeria monocytogenes (LM) which induces massive T cell activation, the influence of T cell stimulation on memory development was discerned. It was hypothesized that muted activation of CD8+ T cells by BCG might result in impaired development of memory. It was found that in contrast to LM naive as well as memory CD8+ T cells undergo delayed and muted expansion and contraction during BCG infection. Memory CD8+ T cells remained functional as they expressed cytokines, killed targets and proliferated in response to antigen. Furthermore, inflammatory cytokines and T cells curtail antigen-presentation during BCG infection which curbs T cell stimulation and favors the development of functional memory.
Circulating levels of bioavailable testosterone and estradiol as risk factors for decline in cognition Results from the Canadian Study of Health and Aging

description: Using the data from the 1991-2001 Canadian Study of Health and Aging, this study examined the association between sex hormone levels and cognitive decline. The objective was to reach a better understanding of the effect of sex steroid hormones on cognition in men and women over the age of 65. Initial hypotheses postulated the existence of a protective effect of circulating hormone levels on the risk of developing dementia. This would support the judicious use of hormone replacement therapy (testosterone and/or estradiol) in dementia; either delaying the onset of dementia or slowing its progress. The results from this study did not reveal any significant association between the circulating levels of total testosterone, bioavailable testosterone, estradiol or the E2/SHBG ratio and cognitive decline. In the logistic regression, the ORs were all very near 1 and not statistically significant. This led us to question the impact of the lack of sensitivity of assays for testosterone and estradiol because in an elderly population when the hormone levels are at their lowest. Also, the small sample size and heterogeneity in a number of diagnostic groups could account for the absence of statistical significance. (Abstract shortened by UMI.)
Investigation of transfer pricing models among a network firm for a distributed product

Subjects: subject: Engineering, System Science.

description: This work investigates transfer pricing models among network-manufacturing firms for a distributed product. The particularities of the models are: instead of each company trying to maximize individually the value added to its supply chain in which it is embedded, The models propose to maximize the value added by the network-companies in the global supply chain. Under specific assumptions on the nature of production, cost and value functions in typical production/distribution companies, it optimizes the supply chain structure for network-companies, distributed in one economic region. We calculate the transfer price and share the value added between the networked firms by two approaches: resource-based approach and efficiency-based approach. The models are formally defined, optimally formulated, and solved.

description: The purpose of this study was to develop a better understanding of the body image, eating habits, and health perceptions of girls in a rural Ontarian elementary school using the Comprehensive School Health program. A case-study design was used for this project. Two interviews were conducted with the principal and with the 6th grade teacher. In addition, two focus groups were held with the girls of the 6th grade. The focus groups consisted of group discussions with the girls, the administration of the Collins Body Figures Scale (Collins, 1991), as well as a shortened version of the Children's Eating Attitude Test-26 questionnaire (ChEAT-26) (Maloney, McGuire, & Daniels, 1988). The results showed that there were very few health education initiatives related to body image and nutrition for the grade 6 class of the school, and suggested that the girls had healthy eating habits and low levels of body dissatisfaction.
Controlling the "Chinese" of the eastern states? Maine's constitutional amendment of 1893, electoral reform, and anti-French-Canadian bias

description: This thesis examines a constitutional amendment adopted by the State of Maine in 1893 as part of an electoral reform package. It stated that any man who could not read the State Constitution in English or write his name on or after January 3, 1893 was not qualified to vote. Although some of the amendment's supporters claimed the measure would raise the quality of the state electorate, most supported it because it targeted immigrants, more particularly, French Canadian immigrants. Anglo-Republicans who supported the amendment discriminated against French-Canadians, who were Catholic, spoke French, and chose acculturation rather than assimilation. The amendment was meant to disenfranchise a large proportion of these voters, as many of them were illiterate, French speaking migrants. However, the impact of the amendment proved to be limited. It did not affect Franco-American allegiances to politicians or political parties they thought best supported their wants and needs. This may be why the amendment was quickly forgotten and is not mentioned in any published history of Maine. Statistics collected from the 1910 census, English and French language newspapers of Lewiston, and an out of state newspaper provide much of the primary sources for this work.
Momentum space separation of quantum path interferences between photons and surface plasmon polaritons in nonlinear photoemission microscopy

description: Quantum path interferences occur whenever multiple equivalent and coherent transitions result in a common final state. Such interferences strongly modify the probability of a particle to be found in that final state, a key concept of quantum coherent control. When multiple nonlinear and energy-degenerate transitions occur in a system, the multitude of possible quantum path interferences is hard to disentangle experimentally. Here, we analyze quantum path interferences during the nonlinear emission of electrons from hybrid plasmonic and photonic fields using time-resolved photoemission electron microscopy. We experimentally distinguish quantum path interferences by exploiting the momentum difference between photons and plasmons and through balancing the relative contributions of their respective fields. Our work provides a fundamental understanding of the nonlinear photon-plasmon-electron interaction. Distinguishing emission processes in momentum space, as introduced here, will ultimately allow nano-optical quantum-correlations to be studied without destroying the quantum path interferences.

description: The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet with unbound orbits. We analyze an asteroidal grazing meteor (FH1) recorded by the Finnish Fireball Network on October 23, 2022. FH1 displayed a likely hyperbolic orbit lying on the ecliptic plane with an estimated velocity excess of $\sim$0.7 km$\,$s$^{-1}$ at impact. FH1 may either be an interstellar object, indicating a high-strength bias in this population, or an Oort cloud object, which would reinforce migration-based solar system models. Furthermore, under the calculated uncertainties, FH1 could potentially be associated with the passage of Scholz's binary star system. Statistical evaluation of uncertainties in the CNEOS database and study of its hyperbolic fireballs reveals an anisotropic geocentric radiant distribution and low orbital inclinations, challenging the assumption of a randomly incoming interstellar population. Orbital integrations suggest that the event on March 9, 2017 (IM2) from CNEOS may have experienced gravitational perturbation during the Scholz fly-by, contingent upon velocity overestimation within the expected range. These findings suggest that apparent interstellar meteors may, in fact, be the result of accelerated meteoroid impacts caused by close encounters with massive objects within or passing through our solar system.

description: We show that the recent construction of $N_f=1$ baryons on the $η^\prime$ domain wall can be understood as vortexes of the principal effective theory -- the Chern-Simons-Higgs theory -- on a 2+1-dimensional sheet. This theory has a series of vertex solutions, and the vortex with unit topological charge naturally spins $N_c/2$, which coincides with the spin of the one-flavor baryon in QCD. Since the $N_c$ scaling of the vortexes is the same as that of baryons, baryons can be regarded as vortexes. By virtue of the particle-vortex symmetry, the dual Zhang-Hansson-Kivelson theory indicates that the quark carries topological charge $1/N_c$ and obeys fractional statistics. The generalization to arbitrary $N_f$ is also discussed.

description: In recent decades, the use of optical detection systems for meteor studies has increased dramatically, resulting in huge amounts of data being analyzed. Automated meteor detection tools are essential for studying the continuous meteoroid incoming flux, recovering fresh meteorites, and achieving a better understanding of our Solar System. Concerning meteor detection, distinguishing false positives between meteor and non-meteor images has traditionally been performed by hand, which is significantly time-consuming. To address this issue, we developed a fully automated pipeline that uses Convolutional Neural Networks (CNNs) to classify candidate meteor detections. Our new method is able to detect meteors even in images that contain static elements such as clouds, the Moon, and buildings. To accurately locate the meteor within each frame, we employ the Gradient-weighted Class Activation Mapping (Grad-CAM) technique. This method facilitates the identification of the region of interest by multiplying the activations from the last convolutional layer with the average of the gradients across the feature map of that layer. By combining these findings with the activation map derived from the first convolutional layer, we effectively pinpoint the most probable pixel location of the meteor. We trained and evaluated our model on a large dataset collected by the Spanish Meteor Network (SPMN) and achieved a precision of 98\%. Our new methodology presented here has the potential to reduce the workload of meteor scientists and station operators and improve the accuracy of meteor tracking and classification.

description: Molecular basis of Influenza A virulence is not fully understood. This study focuses on the Hemagglutinin (HA) protein since it is known to be a critical determinant of virulence. The experimental approach used was mouse adaptation. The prototype clinical isolate A/HK/1/68 (H3N2) was subjected to serial mouse to mouse passages. Following longitudinal and parallel studies 11 mouse adapted populations were generated. Sequence analysis of all 11 populations identified a total of 24 mutations within the HA gene. These mutations clustered in two areas within the 3 dimensional structure. One adaptive region resides within the HA1 while the other is located in the HA2 domain. Four of the mouse adapted HA mutations exhibited evidence of convergent evolution. Three of these mutations (P162L/S, Q210R and G218W/E) reside in HA1 while one mutation (N154S/K) is located in HA2. Recombinant viruses possessing convergent HA mutations exhibited altered receptor binding and pH of fusion. These mutations increased infection and replication within the mouse lung (in vivo) and/or mTECs (in vitro). However, different infection patterns were observed indicating that distinct alpha2,3 SA receptors might be present in the tracheal, bronchial and alveolar cells. In addition, adaptive mutations in HA1 as well as HA2 were associated with enhanced virulence. Certain mouse adapted mutations parallel changes observed in other virulent variants. This identifies them as putative virulence determinants. Hence, these mutations can serve as predictors of virulence.

description: Dans cette recherche, nous avons essayé de répondre à la question de savoir si les Églises africaines anciennes disposaient d'un patrimoine économique important et, surtout, comment elles l'avaient acquis. Le décryptage de différentes sources archéologiques, historiques et théologiques que nous avons interrogées nous a dévoilé les résultats ci-après: 1° L'existence d'un patrimoine économique pour les Églises africaines ne fait pas l'ombre d'un doute. Ce patrimoine s'est constitué au fil de temps et selon des circonstances historiques, sociales et économiques de la région de l'Afrique romaine. Moins spectaculaires pendant les persécutions, c'est-à-dire jusqu'à la première moitié du IIIe siècle, les biens économiques des Églises africaines se sont accru dans la seconde moitié du IIIe et sont devenus importants dès le début du IVe siècle. La paix ramenée en Occident à l'avènement de Constantin y avait certainement contribué. 2° Mais contrairement au patrimoine ecclésiastique de Rome, constitué essentiellement par les donations de Constantin, celui de l'Église d'Afrique provenait en majeure partie des offrandes des fidèles et des activités lucratives légitimées par les institutions ecclésiastiques africaines elles-mêmes. 3° La situation économique on ne peut plus prospère de l'Afrique, mais surtout la foi en la bonté des biens de la création, la Clementia Dei et en l'expérience pastorale du Christ - lequel disposait d'une bourse pour ses disciples -, inculquée aux chrétiens africains, ont servi de support incontournable à la constitution du patrimoine ecclésiastique africain. L'argumentaire est ainsi organise en trois chapitres de volume presque égal, selon la méthode historico-théologique. Notre objectif dans une telle étude est double. Il s'agit d'abord d'écrire le chapitre économique qui jusqu'ici faisait défaut à la vitalité flamboyante des communautés chrétiennes antiques et, ensuite, d'en trouver ou de définir le support socio-économique et théologique. Cela dans le but de contribuer, tant soit peu, aux efforts de recherche d'autonomie financière et d'élaboration d'un cadre théologique et praxiologique pour les Églises d'aujourd'hui. N'est-ce pas la réveiller à l'Église sa vocation de "Lumen gentium", dans un monde ou l'économique tend à devenir le leitmotiv de presque toutes les fibres voire institutions sociales?

description: Hot plasma is highly conductive in the direction parallel to a magnetic field. This often means that the electrical potential will be nearly constant along any given field line. When this is the case, the cross-field voltage drops in open-field-line magnetic confinement devices are limited by the tolerances of the solid materials wherever the field lines impinge on the plasma-facing components. To circumvent this voltage limitation, it is proposed to arrange large voltage drops in the interior of a device, but coexisting with much smaller drops on the boundaries. To avoid prohibitively large dissipation requires both preventing substantial drift-flow shear within flux surfaces and preventing large parallel electric fields from driving large parallel currents. It is demonstrated here that both requirements can be met simultaneously, which opens up the possibility for magnetized plasma tolerating steady-state voltage drops far larger than what might be tolerated in material media.

The Experience of Oncology Nurses who Provide Bereavement Support

description: Oncology nurses are present in varying degrees in the lives of cancer patients and their families as they journey through the cancer trajectory. When the patient dies, it is common practice for the therapeutic relationship between the nurse and the family to end, leaving the bereaved individual without this relationship during the difficult bereavement period. Although bereavement has been acknowledged as a period of increased morbidity and overuse of health care system resources, nurse-led bereavement support programs are not commonplace in tertiary care settings. Currently, very little is known of the experience of oncology nurses who provide bereavement support, and scant research exists regarding the needs of nurses who take on bereavement support in addition to their main nursing role. This lack of knowledge and understanding of the role and experience of oncology nurses who provide bereavement support can impact on services provided to bereaved individuals.
The candidate tumour suppressor, XIAP associated factor 1 (XAF1), directly inhibits XIAP activity and induces G1 phase cell cycle arrest

description: X&barbelow;IAP a&barbelow;ssociated f&barbelow;actor 1&barbelow; (XAF1) was initially isolated as novel 34 kDa protein which bound XIAP in a two-hybrid screening. The XAF1A protein consists of 301 a.a. and contains seven potential zinc finger domains. Two alternatively splice variants of XAF1 were later isolated. One isoform (XAF1B) was formed by the removal of a 57 bp exon, which leads to an in-frame deletion of the third zinc finger and the creation of a shorter 32.5 kDa protein. The other splice variant (XAF1C) contains a 154 bp exon insertion, which truncates the sixth and seventh zinc fingers to produce an 18.7 kDa protein. XAF1A and XAF1B, but not XAF1C, bound XIAP in in vitro pull down assays. Northern blot analysis showed at least four distinct sizes of xaf1 mRNA ranging between 3.9 and 7.0 kb, which may indicate other XAF1 isoforms yet to be discovered. Though the possible role of these zinc fingers on the XAF1/XIAP interaction has yet to be determined, recent experiments indicate that XAF1A can block the ability of XIAP to inhibit caspase-3 in vitro. Furthermore, overexpression of XAF1A in HEL299 cells triggered a G1 cell cycle arrest. This G1 arrest coincides with an increase in p21, but not p53. The ability of XAF1 to block XIAP function and induce cell cycle arrest suggests a role for XAF1 in the control of both apoptosis and cell growth. The coding regions of XAF1A, B and C are encoded on a total of 9 exons within a span of 20 kb. The single copy xaf1 gene has been mapped, using FISH analysis, distal to the TP53 gene on 17p13.2. Southern blot analysis of YACS within this region further localizes the xaf1 gene on YAC 746 C 10, which contains the markers D17S1831, D17S796, and D17S1881. These markers are located approximately 3 cM telomeric to the TP53 gene. Since the xaf1 gene is located in a region commonly deleted in numerous types of cancers, this may suggest a tumour suppressor role for XAF1 in cancer. To test this theory, a 60 cell line panel from the NCl was analyzed for xaf1 RNA expression by Taqman and heterozygosity status of markers proximal to xaf1. Taqman analysis indicated that the majority of cell lines expressed little or no xaf1 RNA while xiap levels were relatively high. A PCR study of markers near xaf1 showed significant loss of heterozygosity (LOH) in this region. The loss of xaf1 expression and significant LOH near the xaf1 gene indicate that the down-regulation of XAF1 may be important in the development of the transformed phenotype.
