Portrait de l'écrivain en ascète: Ralph Waldo Emerson et la modernité des exercices spirituels

[À l'origine dans / Was originally part of : Thèses et mémoires - FAS - Département de littérature comparée]Ce mémoire démontre que la pratique littéraire de l’écrivain américain Ralph Waldo Emerson s’inscrit dans le sillage de la tradition des exercices spirituels mise au jour par l’helléniste Pierre Hadot et qu’elle permet de penser une modernité insoupçonnée par ce dernier. La production de textes littéraires devient alors une manière d’établir « une relation originale avec l’univers » (cf. l’introduction de Nature). Le premier chapitre explique la spécificité de la spiritualité traditionnelle, où l’écriture consiste à implanter en soi le texte de la tradition. La pratique littéraire de Marc Aurèle, Sénèque et saint Augustin est étudiée afin de montrer comment ils tâchent de vivre conformément à la conception de la transcendance qui est la leur : personnelle chez les stoïciens, institutionnelle chez les chrétiens. Le deuxième chapitre montre comment Emerson renverse le rapport traditionnel au texte dans la vie de l’esprit en arguant que la révélation du Christ est, à l’origine, une expérience personnelle de la transcendance qui n’est pas institutionnalisable. Il se dégage de cette confrontation romantique avec le christianisme un concept de littérature lié au mysticisme et inséparable d’une compréhension « expressiviste » du langage (Charles Taylor). Le dernier chapitre examine l’ascèse littéraire d’Emerson : sa conception antiscolastique du « scholar » est étudiée puis mise en relief avec sa façon d’arrimer sa pratique de la pensée à une conception fluctuante de l’univers. La dernière section porte sur la façon dont son mode de vie expérimental suppose une conception de la littérature en tant que processus.This master thesis considers how the literary practice of Ralph Waldo Emerson might help us rethink the modern heritage in the tradition of spiritual exercises. The nineteenth century American writer followed the path of this antique tradition that was uncovered by the philosophy historian Pierre Hadot, allowing us to consider anew this tradition within the framework of modernity. It is thus possible to access an unexpected modernity of spiritual exercises, unknown to Hadot himself, characterized by the production of literary texts that convey what Emerson calls, “an original relation to the universe.” The first chapter explains the specificity of traditional spirituality, where writing serves to incorporate traditional text into oneself. It considers the literary practice of Marcus Aurelius, Seneca and Saint Augustine, who all attempted to live according to their conception of transcendence: personal under stoicism, institutional within Christianity. Chapter two illustrates how Emerson overturns the traditional way of behaving with a spiritual text. His critique of Christian theology shows that the revelation of Christ is, in its origin, a personal experience of transcendence that cannot be instituted. From this romantic dissension with Christianity emerges a theory of literature related to mysticism and in close ties with an “expressivist” conception of language (Charles Taylor). The final chapter examines Emerson’s literary askesis. First explained is the antischolastic conception of the scholar, subsequently showing how his way of thinking is interrelated to a fluxional conception of the universe. Lastly demonstrated is how his experimental way of life relies on a conception of literature as process

Comparing the behavioural thermoregulation response to heat stress by Atlantic salmon parr ( Salmo salar ) in two rivers

Climate change is expected to increase the frequency and magnitude of extreme thermal events in rivers. The Little Southwest Miramichi River (LSWM) and the Ouelle River (OR) are two Atlantic salmon (Salmo salar) rivers located in eastern Canada, where in recent years, water temperatures have exceeded known thermal limits (~23°C). Once temperature surpasses this threshold, juvenile salmon exploit thermal heterogeneity to behaviourally thermoregulate, forming aggregations in coolwater refuges. This study aimed to determine whether the behavioural thermoregulation response is universal across rivers, arising from common thermal cues. We detailed the temperature and discharge patterns of two geographically distinct rivers from 2010 to 2012 and compared these with aggregation onset temperature. PIT telemetry and snorkelling were used to confirm the presence of aggregations. Mean daily maximum temperature in 2010 was significantly greater in the OR versus the LSWM (p = 0.005), but not in other years (p = 0.090–0.353). Aggregations occurred on 14 and 9 occasions in the OR and LSWM respectively. Temperature at onset of aggregation was significantly greater in the OR (Tonset = 28.3°C) than in the LSWM (Tonset = 27.3°C; p = 0.049). Logistic regression models varied by river and were able to predict the probability of aggregation based on the preceding number of hours >23°C (R2 = 0.61 & 0.65; P50 = 27.4°C & 28.9°C; in the OR and LSWM respectively). These results imply the preceding local thermal regime may influence behaviour and indicate a degree of phenotypic plasticity, illustrating a need for localised management strategies

Canadian Healthcare Professionals’ Views and Attitudes toward Risk-Stratified Breast Cancer Screening

Given the controversy over the effectiveness of age-based breast cancer (BC) screening, offering risk-stratified screening to women may be a way to improve patient outcomes with detection of earlier-stage disease. While this approach seems promising, its integration requires the buy-in of many stakeholders. In this cross-sectional study, we surveyed Canadian healthcare professionals about their views and attitudes toward a risk-stratified BC screening approach. An anonymous online questionnaire was disseminated through Canadian healthcare professional associations between November 2020 and May 2021. Information collected included attitudes toward BC screening recommendations based on individual risk, comfort and perceived readiness related to the possible implementation of this approach. Close to 90% of the 593 respondents agreed with increased frequency and earlier initiation of BC screening for women at high risk. However, only 9% agreed with the idea of not offering BC screening to women at very low risk. Respondents indicated that primary care physicians and nurse practitioners should play a leading role in the risk-stratified BC screening approach. This survey identifies health services and policy enhancements that would be needed to support future implementation of a risk-stratified BC screening approach in healthcare systems in Canada and other countries

Analysis of Virion Structural Components Reveals Vestiges of the Ancestral Ichnovirus Genome

Many thousands of endoparasitic wasp species are known to inject polydnavirus (PDV) particles into their caterpillar host during oviposition, causing immune and developmental dysfunctions that benefit the wasp larva. PDVs associated with braconid and ichneumonid wasps, bracoviruses and ichnoviruses respectively, both deliver multiple circular dsDNA molecules to the caterpillar. These molecules contain virulence genes but lack core genes typically involved in particle production. This is not completely unexpected given that no PDV replication takes place in the caterpillar. Particle production is confined to the wasp ovary where viral DNAs are generated from proviral copies maintained within the wasp genome. We recently showed that the genes involved in bracovirus particle production reside within the wasp genome and are related to nudiviruses. In the present work we characterized genes involved in ichnovirus particle production by analyzing the components of purified Hyposoter didymator Ichnovirus particles by LC-MS/MS and studying their organization in the wasp genome. Their products are conserved among ichnovirus-associated wasps and constitute a specific set of proteins in the virosphere. Strikingly, these genes are clustered in specialized regions of the wasp genome which are amplified along with proviral DNA during virus particle replication, but are not packaged in the particles. Clearly our results show that ichnoviruses and bracoviruses particles originated from different viral entities, thus providing an example of convergent evolution where two groups of wasps have independently domesticated viruses to deliver genes into their hosts

A collaborative model to implement flexible, accessible and efficient oncogenetic services for hereditary breast and ovarian cancer : the C-MOnGene study

Medical genetic services are facing an unprecedented demand for counseling and testing for hereditary breast and ovarian cancer (HBOC) in a context of limited resources. To help resolve this issue, a collaborative oncogenetic model was recently developed and implemented at the CHU de Québec-Université Laval; Quebec; Canada. Here, we present the protocol of the C-MOnGene (Collaborative Model in OncoGenetics) study, funded to examine the context in which the model was implemented and document the lessons that can be learned to optimize the delivery of oncogenetic services. Within three years of implementation, the model allowed researchers to double the annual number of patients seen in genetic counseling. The average number of days between genetic counseling and disclosure of test results significantly decreased. Group counseling sessions improved participants' understanding of breast cancer risk and increased knowledge of breast cancer and genetics and a large majority of them reported to be overwhelmingly satisfied with the process. These quality and performance indicators suggest this oncogenetic model offers a flexible, patient-centered and efficient genetic counseling and testing for HBOC. By identifying the critical facilitating factors and barriers, our study will provide an evidence base for organizations interested in transitioning to an oncogenetic model integrated into oncology care; including teams that are not specialized but are trained in genetics
