description: In recent years, notable progress has been made in the study of hole qubits in planar germanium, and circuit quantum electrodynamics (circuit QED) has emerged as a promising approach for achieving long-range coupling and scaling up of qubits. Here, we demonstrate the coupling between holes in a planar germanium double quantum dot (DQD) and photons in a microwave cavity. Specifically, a real-time calibrated virtual gate method is developed to characterize this hybrid system, which in turn allows us to determine the typical parameters sequentially through single-parameter fitting instead of conventional multi-parameter fitting with additional uncertainty, and gives the hole-photon coupling rate of $g_0/2π$ = 21.7 MHz. This work is a step toward further research on hole-photon interactions and long-range qubit coupling in planar germanium. The experimental method developed in this work contributes to the more accurate and efficient characterization of hybrid cavity-QED systems.

description: Background The likelihood of recurrence in patients with breast cancer who have HER2-positive tumors is relatively high, although trastuzumab is a remarkably effective drug in this setting. Signal transducer and activator of transcription 3 protein (STAT3), a transcription factor that is persistently tyrosine-705 phosphorylated (pSTAT3) in response to numerous oncogenic signaling pathways, activates downstream proliferative and anti-apoptotic pathways. We hypothesized that pSTAT3 expression in HER2-positive breast cancer will confer trastuzumab resistance. Methods We integrated reverse phase protein array (RPPA) and gene expression data from patients with HER2-positive breast cancer treated with trastuzumab in the adjuvant setting. Results We show that a pSTAT3-associated gene signature (pSTAT3-GS) is able to predict pSTAT3 status in an independent dataset (TCGA; AUC = 0.77, P = 0.02). This suggests that STAT3 induces a characteristic set of gene expression changes in HER2-positive cancers. Tumors characterized as high pSTAT3-GS were associated with trastuzumab resistance (log rank P = 0.049). These results were confirmed using data from the prospective, randomized controlled FinHer study, where the effect was especially prominent in HER2-positive estrogen receptor (ER)-negative tumors (interaction test P = 0.02). Of interest, constitutively activated pSTAT3 tumors were associated with loss of PTEN, elevated IL6, and stromal reactivation. Conclusions This study provides compelling evidence for a link between pSTAT3 and trastuzumab resistance in HER2-positive primary breast cancers. Our results suggest that it may be valuable to add agents targeting the STAT3 pathway to trastuzumab for treatment of HER2-positive breast cancer.
Towards a reticular analysis of Josquin's five-voice "Chansons"

Subjects: subject: Music.

description: The examination of Josquin's five-voice chanson repertoire provides an overview of historical information about composer, the chanson as a musical genre, and the manuscript sources containing them. Furthermore, it advances the knowledge of the musical structure and text expression of the works. Analysis of this repertoire by means of Joshua Rifkin's concept of motivicity attempts to advance the understanding of the compositional process in the early Renaissance. Motivicity proved useful as a tool not only in this regard, but also by making apparent needed changes to the text underlay. A discussion of the concept of modal affect or ethos and its relevance to secular polyphony of the early Renaissance opened up the question of text expression in Josquin's five-voice chanson repertoire, a subject still requiring further investigation.

description: Background: Physical exercise, cognitive training, and vitamin D are low cost interventions that have the potential to enhance cognitive function and mobility in older adults, especially in pre-dementia states such as Mild Cognitive Impairment (MCI). Aerobic and progressive resistance exercises have benefits to cognitive performance, though evidence is somewhat inconsistent. We postulate that combined aerobic exercise (AE) and progressive resistance training (RT) (combined exercise) will have a better effect on cognition than a balance and toning control (BAT) intervention in older adults with MCI. We also expect that adding cognitive training and vitamin D supplementation to the combined exercise, as a multimodal intervention, will have synergistic efficacy. Methods: The SYNERGIC trial (SYNchronizing Exercises, Remedies in GaIt and Cognition) is a multi-site, double-blinded, five-arm, controlled trial that assesses the potential synergic effect of combined AE and RT on cognition and mobility, with and without cognitive training and vitamin D supplementation in older adults with MCI. Two-hundred participants with MCI aged 60 to 85 years old will be randomized to one of five arms, four of which include combined exercise plus combinations of dual-task cognitive training (real vs. sham) and vitamin D supplementation (3 × 10,000 IU/wk. vs. placebo) in a quasi-factorial design, and one arm which receives all control interventions. The primary outcome measure is the ADAS-Cog (13 and plus modalities) measured at baseline and at 6 months of follow-up. Secondary outcomes include neuroimaging, neuro-cognitive performance, gait and mobility performance, and serum biomarkers of inflammation (C reactive protein and interleukin 6), neuroplasticity (brain-derived neurotropic factor), endothelial markers (vascular endothelial growth factor 1), and vitamin D serum levels. Discussion: The SYNERGIC Trial will establish the efficacy and feasibility of a multimodal intervention to improve cognitive performance and mobility outcomes in MCI. These interventions may contribute to new approaches to stabilize and reverse cognitive-mobility decline in older individuals with MCI.

Ziel war es, Kenntnisse über den Status quo der Stromkennzeichnung als Verbraucherinformation bei der Ökostromauswahl sowie allgemeine Einstellungen der Verbraucherinnen und Verbraucher zum Thema Ökostrom und zur Energiewende zu erlangen. Die Studie zeigt repräsentative Ergebnisse für die deutsche Bevölkerung. Kernerkenntnisse sind, dass die Stromkennzeichnung bei dem Großteil der Deutschen nicht bekannt ist und daher nicht zum Vergleich verschiedener Produkte oder Anbieter genutzt wird. Gleichwohl besteht großes Potenzial für einen vermehrten Ökostrombezug, bei dessen Auswahl auch die Stromkennzeichnung eine wesentlich größere Rolle spielen kann. Als Wechselbarrieren hin zu Ökostrom werden vor allem zu hohe Preise und zu wenig Informationen benannt. Quelle: Forschungsbericht

description: The purpose of this research was to use Young et al.'s (2003) schema theory in the context of cyberbullying to explain the variation in psychological distress experienced by targets. Study 1 provided an in-depth understanding as to how emerging adults define cyberbullying; and Study 2 developed an instrument measuring the specific schema coping styles proposed by Young et al. The findings from both studies informed a model tested in Study 3, which provided empirical support for Young et al.'s schema theory where it appears schema activation and schema coping style affect the level of psychological distress experienced by targets of cyberbullying.

Speech quality evaluation using digital watermarking

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: Computer Science.

description: Speech quality evaluation is a very important research topic. The Mean Opinion Score (MOS) is reliable but the listening test is very expensive, time consuming, and even impractical for some applications. Objective quality evaluation methods require either the original speech or a complicated computation model, which makes some applications of quality evaluation impossible. Different from the perceptual model used by the Perceptual Evaluation of Speech Quality (PESQ), in this thesis, we propose to use digital audio watermarking to evaluate the quality of speech. Based on quantization, watermark bits are embedded and extracted in the Discrete Wavelet Transform (DWT) domain. By comparing the original and the extracted watermark, we predict the quality of speech that has undergone MP3 compression, Gaussian noise addition, low-pass filtering, or packet loss. Our quality evaluation method does not need the original signal or a computation model. For the quality evaluation, we use the PESQ MOS as a reference. We predict the speech quality from the PCEW (Percentage of Correctly Extracted Watermark bits) based on the mapping between ITU-T P.862 PESQ MOS and the PCEW. To evaluate the performance of our objective quality evaluation method, we introduce the correlation coefficient and residual error to evaluate the correlation between the predicted MOS and the PESQ MOS. The experiments show that the method yields very promising evaluation results which are very close to the results of the PESQ.

description: Consider the smooth sections of the tangent bundle of a reductive homogeneous space. This is a vector space over the field of real numbers. The canonical connection acts as a linear binary operator on this vector space, making it an algebra. If we include another binary operator defined as the negative of the torsion, the resulting algebraic structure is a post-Lie-Yamaguti algebra. This structure is closely related to Lie-Yamaguti algebras.

description: Mathematical models of protein-protein dynamics, such as the heterodimer model, play a crucial role in understanding many physical phenomena. This model is a system of two semilinear parabolic partial differential equations describing the evolution and mutual interaction of biological species. An example is the neurodegenerative disease progression in some significant pathologies, such as Alzheimer's and Parkinson's diseases, characterized by the accumulation and propagation of toxic prionic proteins. This article presents and analyzes a flexible high-order discretization method for the numerical approximation of the heterodimer model. We propose a space discretization based on a Discontinuous Galerkin method on polygonal/polyhedral grids, which provides flexibility in handling complex geometries. Concerning the semi-discrete formulation, we prove stability and a-priori error estimates for the first time. Next, we adopt a $θ$-method scheme as a time integration scheme. Convergence tests are carried out to demonstrate the theoretical bounds and the ability of the method to approximate traveling wave solutions, considering also complex geometries such as brain sections reconstructed from medical images. Finally, the proposed scheme is tested in a practical test case stemming from neuroscience applications, namely the simulation of the spread of $α$-synuclein in a realistic test case of Parkinson's disease in a two-dimensional sagittal brain section geometry reconstructed from medical images.

description: We present the 2-degree Field Lensing Survey (2dFLenS), a new galaxy redshift survey performed at the Anglo-Australian Telescope. 2dFLenS is the first wide-area spectroscopic survey specifically targeting the area mapped by deep-imaging gravitational lensing fields, in this case the Kilo-Degree Survey. 2dFLenS obtained 70 079 redshifts in the range z < 0.9 over an area of 731 deg2, and is designed to extend the data sets available for testing gravitational physics and promote the development of relevant algorithms for joint imaging and spectroscopic analysis. The redshift sample consists first of 40 531 Luminous Red Galaxies (LRGs), which enable analyses of galaxy-galaxy lensing, redshift-space distortion, and the overlapping source redshift distribution by cross-correlation. An additional 28 269 redshifts form a magnitude-limited (r < 19.5) nearly complete subsample, allowing direct source classification and photometric-redshift calibration. In this paper, we describe the motivation, target selection, spectroscopic observations, and clustering analysis of 2dFLenS. We use power spectrum multipole measurements to fit the redshift-space distortion parameter of the LRG sample in two redshift ranges 0.15 < z < 0.43 and 0.43 < z < 0.7 as β = 0.49 ± 0.15 and β = 0.26 ± 0.09, respectively. These values are consistent with those obtained from LRGs in the Baryon Oscillation Spectroscopic Survey. 2dFLenS data products will be released via our website http://2dflens.swin.edu.au.
Investigating the Function of Hemogen during Erythroid Differentiation

Year: 2010
Subjects: subject: Biology, Molecular.

description: Hemogen is a murine protein expressed in active sites of hematopoiesis during embryogenesis and in the adult. Hemogen's function has not been clearly elucidated. Evidences suggest Hemogen's role in erythroid differentiation. Hemogen expression coincides with active sites of erythropoiesis. beta-globin expression is a hallmark of erythroid differentiation. Proteomic data suggests that Hemogen associates with MafK which is part of the NF-E2 complex that acts as an activator of beta-globin during erythroid differentiation. To gain insight into Hemogen's mechanistic function during erythroid differentiation, we attempted to decipher Hemogen's associating proteins during erythroid differentiation. We generated a Hemogen antibody functional in Hemogen immunoprecipitation (IP). We performed Hemogen IP and used mass spectrometry to identify putative Hemogen interacting proteins within the Hemogen IP elution. Our immuno-fluorescence microscopy (IFM) images of endogenous Hemogen revealed Hemogen as a nuclear protein within murine erythroleukemia cells before and after differentiation. In line with our IFM images, the majority of candidates identified within our putative list of Hemogen associating proteins are transcription regulators. Hemogen expression progressively increased with erythroid differentiation. Hence, Hemogen may function as a transcriptional regulator during erythroid differentiation.

description: The aim of European water policy is to achieve good ecological status in all rivers, lakes, coastal and transitional waters by 2027. Currently, more than half of water bodies are in a degraded condition and nutrient enrichment is one of the main culprits. Therefore, there is a pressing need to establish reliable and comparable nutrient criteria that are consistent with good ecological status. This paper highlights the wide range of nutrient criteria currently in use by Member States of the European Union to support good ecological status and goes on to suggest that inappropriate criteria may be hindering the achievement of good status. Along with a comprehensive overview of nutrient criteria, we provide a critical analysis of the threshold concentrations and approaches by which these are set. We identify four essential issues: (1) Different nutrients (nitrogen and/or phosphorus) are used for different water categories in different countries. (2) The use of different nutrient fractions (total, dissolved inorganic) and statistical summary metrics (e.g., mean, percentiles, seasonal, annual) currently hampers comparability between countries, particularly for rivers, transitional and coastal waters. (3) Wide ranges in nutrient threshold values within shared water body types, in some cases showing more than a 10-fold difference in concentrations. (4) Different approaches used to set threshold nutrient concentrations to define the boundary between "good" and "moderate" ecological status. Expert judgement-based methods resulted in significantly higher (less stringent) good-moderate threshold values compared with data-driven approaches, highlighting the importance of consistent and rigorous approaches to criteria setting. We suggest that further development of nutrient criteria should be based on relationships between ecological status and nutrient concentrations, taking into account the need for comparability between different water categories, water body types within these categories, and countries. © 2019 The Authors.

description: Background: Nosocomial, or healthcare-associated infections (HAI), exact a high medical and financial toll on patients, healthcare workers, caretakers, and the health system. Interpersonal contact patterns play a large role in infectious disease spread, but little is known about the relationship between health care workers’ (HCW) movements and contact patterns within a heath care facility and HAI. Quantitatively capturing these patterns will aid in understanding the dynamics of HAI and may lead to more targeted and effective control strategies in the hospital setting. Methods: Staff at 3 urban university-based tertiary care hospitals in Canada completed a detailed questionnaire on demographics, interpersonal contacts, in-hospital movement, and infection prevention and control practices. Staff were divided into categories of administrative/support, nurses, physicians, and “Other HCWs” - a fourth distinct category, which excludes physicians and nurses. Using quantitative network modeling tools, we constructed the resulting HCW “co-location network” to illustrate contacts among different occupations and with locations in hospital settings. Results: Among 3048 respondents (response rate 38%) an average of 3.79, 3.69 and 3.88 floors were visited by each HCW each week in the 3 hospitals, with a standard deviation of 2.63, 1.74 and 2.08, respectively. Physicians reported the highest rate of direct patient contacts (> 20 patients/day) but the lowest rate of contacts with other HCWs; nurses had the most extended (> 20 min) periods of direct patient contact. “Other HCWs” had the most direct daily contact with all other HCWs. Physicians also reported significantly more locations visited per week than nurses, other HCW, or administrators; nurses visited the fewest. Public spaces such as the cafeteria had the most staff visits per week, but the least mean hours spent per visit. Inpatient settings had significantly more HCW interactions per week than outpatient settings. Conclusions: HCW contact patterns and spatial movement demonstrate significant heterogeneity by occupation. Control strategies that address this diversity among health care workers may be more effective than “one-strategy-fits-all” HAI prevention and control programs.

description: We find a formula for the Virasoro fusion kernel at $c=25$, in terms of the connection coefficients of the Painlevé VI differential equation. Our formula agrees numerically with previously known integral representations of the kernel. The derivation of our formula relies on a duality $c\to 26-c$ that is obeyed by the shift equations for the fusion and modular kernels. We conjecture that for $c<1$ the fusion and modular kernels are not smooth functions, but distributions.

The Microbial Ecology of Urban Organic Solid Waste Treatment (Compost)
Creators: name: Jaimes Castillo, Alex
Publisher: name: Swinburne
Year: 2024

description: Diverting organic waste from landfills and composting it instead, produces compost, which can be used in agriculture or gardening. In this research, two in-vessel units were used to determine whether the treatment process follows a typical composting profile. The physical, chemical and microbial analysis demonstrated that these in-vessel units do not provide optimum conditions for microbial activity. Hence, the end-products are not compost and require further treatment. In order to improve the conditions of the composting process, an eco-efficient in-vessel composter prototype was built. This prototype provides optimum conditions for microbial activity and follows the typical composting profile. The active phase of composting ends in nine days, where high temperature (65°C) pasteurise the product. At these conditions, Firmicutes and Proteobacteria phyla dominate the composting process. The curing phase requires an additional 51 days to reach maturity. At this stage, Bacteroidetes phyla are in higher abundance. Once, the end-product reaches the maturity it is ready to apply as a soil amendment.

description: In this paper we study the hyperbolicity in the sense of Gromov of domains in $\mathbb{R}^d$ $(d\geq3)$ with respect to the minimal metric introduced by Forstnerič and Kalaj. In particular, we prove that every bounded strongly minimally convex domain is Gromov hyperbolic and its Gromov compactification is equivalent to its Euclindean closure. Moreover, we prove that the boundary of a Gromov hyperbolic convex domain does not contain non-trivial conformal harmonic disks. Finally, we study the relation between the minimal metric and the Hilbert metric in convex domains.

description: Dans une perspective nouvelle, la présente étude se propose donc d'étudier sur le plan empirique une dimension qui n'a pas été suffisamment élucidée jusqu'ici: l'Orientation Épistémique en Éducation Physique. Son identification implique de vérifier auprès des spécialistes de l'éducation physique en Tunisie, comment se présente l'orientation épistémique de cette discipline appliquée. Les résultats obtenus viennent appuyer les énoncés du cadre conceptuel proposé, en ce sens que, les praticiens d'une discipline donnée reflètent l'orientation épistémique de leur spécialisation. La confirmation partielle de l'hypothèse de recherche soutient que les étudiants et professeurs intervenant dans le milieu professionnel en éducation physique manifestent communément une orientation épistémique à dominance empirique. Chez les deux groupes de sujets, ce mode préférentiel constitue donc un passage, ou même, un va et vient entre l'assimilation de notions abstraites (savoir théorique) et l'expérience concrète (savoir pratique) tant en formation qu'en milieu professionnel.

Aerosol flow dynamics for mitigating airborne disease transmission indoors
Creators: name: Zabihi, Mojtaba
Publisher: name: University of British Columbia
Year: 2025

description: This dissertation focuses on mitigating airborne disease transmission through two primary strategies: (1) assessing the impact of large-scale indoor airflow patterns and (2) implementing localized airflow control to remove respiratory particles before their dispersion. Large-scale airflow behavior was investigated numerically using a classroom model based on a real university classroom at the University of British Columbia. A new ventilation design, called UFAD-CDR, is proposed. The UFAD-CDR design demonstrated an 85% reduction in airborne particle concentrations compared to baseline ventilation. Furthermore, a new parameter, Horizontality, is introduced to characterize large-scale flow patterns, highlighting their impact and suggesting modifications to ventilation standard codes to account for these effects. The durability of different particle sizes under various ventilation strategies and rates was studied. It was shown that 10 or 15-minute breaks are not sufficient as fallow times unless the ventilation system is specifically designed to mitigate airborne transmission. The effectiveness of localized airflow control was investigated in a consultation room by proposing a novel personalized ventilation (PV) system based on the push-and-pull concept, designed to enhance air quality while preserving occupant comfort. The system was evaluated against conventional PV, baseline ventilation, and offset device positions simulating posture changes during meetings. Results showed a major reduction in infection risk with the new device, lowering probability from 91% (baseline) to 9% after 30 minutes. Conventional PV reduced it to 47.6%, but performed worse than baseline when misaligned. Conversely, the novel system maintained strong performance, similar to an ideally aligned high-flow PV setup (49.8%). A fully transient Eulerian–Lagrangian approach was employed which combines URANS turbulence models with unsteady stochastic tracking of particles to simulate turbulent aerosol dispersion. The numerical model was validated through numerically replicable in-house low-concentration aerosols dispersion experiments. Additionally, among commonly used turbulence models the SST k-ω model showed the best agreement with experiment, due to its more accurate and lower predictions of particle deposition. This was attributed to its superiority near walls, predicting smaller turbulent scales (weaker-shorter-lived eddies). While enabling the turbulent kinetic energy production limiter improved the RNG k-ε accuracy, the SST k-ω remained the most consistent with experimental results.

description: Real-time toxicity detection in online environments poses a significant challenge, due to the increasing prevalence of social media and gaming platforms. We introduce ToxBuster, a simple and scalable model that reliably detects toxic content in real-time for a line of chat by including chat history and metadata. ToxBuster consistently outperforms conventional toxicity models across popular multiplayer games, including Rainbow Six Siege, For Honor, and DOTA 2. We conduct an ablation study to assess the importance of each model component and explore ToxBuster's transferability across the datasets. Furthermore, we showcase ToxBuster's efficacy in post-game moderation, successfully flagging 82.1% of chat-reported players at a precision level of 90.0%. Additionally, we show how an additional 6% of unreported toxic players can be proactively moderated.

Risikoanalyse

description: Irritation of the eyes and the upper respiratory tract are important endpoints for setting guide values for chemicals. To optimize the use of the often-limited data, we analysed controlled human exposure studies (CHS) with 1-4 h inhalation of the test substance, repeated dose inhalation studies in rodents, and Alarie-Tests and derived extrapolation factors (EF) for exposure duration, inter- and intraspecies differences. For the endpoint irritating effects in the respiratory tract in rodents, geometric mean (GM) values of 1.9 were obtained for the EF for subacute ->subchronic (n = 16), 2.1 for subchronic -> chronic (n = 40), and 2.9 for subacute -> chronic (n = 10) extrapolation. Based on these data we suggest an EF of 2 for subchronic -> chronic and of 4 for subacute -> chronic extrapolation. In CHS, exposure concentration determines the effects rather than exposure duration. Slight reversible effects during 4 h exposure indicate that an EF of 1 can be considered for assessing chronic exposures. To assess species extrapolation, 10 chemicals were identified with both, reliable rat inhalation studies and CHS. The GM of the ratio between the No Observed Adverse Effect Concentration (NOAEC) in rats and humans was 2.3 and increased to 3.6 when expanding the dataset to all available EF (n = 25). Based on these analyses, an EF of 3 is suggested to extrapolate from a NOAEC in a chronic rat study to a NOAEC in a CHS. The analysis of EFs for the extrapolation from a 50% decrease in respiratory frequency in the Alarie test in mice (RD50) to a NOAEC in a CHS resulted in a GM of 40, for both, the reliable (n = 11) and the overall dataset (n = 19). We propose to use the RD50 from the Alarie test for setting guide values and to use 40 as EF. Efs for intraspecies differences in the human population must account for susceptible persons, most importantly for persons with chemical intolerance (CI), who show subjective signs of irritation at low concentrations. The limited data available do not justify to deviate from an EF of 10 - 20 as currently used in different regulatory settings. © 2020 The Authors.
The Idea of a University: Enabling or Constraining Possible University Futures?
Creators: name: Conway, Maree
Publisher: name: Swinburne

description: The thesis explored how today's understanding of the Western university's possible futures is constrained by four contested ideas of the university - tacit cultural constructs that shape beliefs about the university's purpose and social legitimacy. The four ideas - Traditional, Managerial, Reframed and Dismissive - were applied to a range of possible future scenarios to identify ways in which current interpretations of the university's futures can expand and deepen. A new conceptual interpretation of 'the idea' and a 'conversations framework' to enable more open and collaborative explorations of the university's futures as an organisation were primary outcomes of the research.
Finite Temperature Entanglement Negativity of Fermionic Symmetry Protected Topological Phases and Quantum Critical Points in One Dimension

description: We study the logarithmic entanglement negativity of symmetry-protected topological (SPT) phases and quantum critical points (QCPs) of one-dimensional noninteracting fermions at finite temperatures. In particular, we consider a free fermion model that realizes not only quantum phase transitions between gapped phases but also an exotic topological phase transition between quantum critical states in the form of the fermionic Lifshitz transition. The bipartite entanglement negativity between adjacent fermion blocks reveals the crossover boundary of the quantum critical fan near the QCP between two gapped phases. Along the critical phase boundary between the gapped phases, the sudden decrease in the entanglement negativity signals the fermionic Lifshitz transition responsible for the change in the topological nature of the QCPs. In addition, the tripartite entanglement negativity between spatially separated fermion blocks counts the number of topologically protected boundary modes for both SPT phases and topologically nontrivial QCPs at zero temperature. However, the long-distance entanglement between the boundary modes vanishes at finite temperatures due to the instability of SPTs, the phases themselves.

description: Saisis par les violences d'actualité, les écrivains de la francophonie se penchent sur les questions de victimisation et de discours mystificateurs, pour éviter que ne sombre dans l'oubli l'être humain place au centre des conflits, tel que le dirait Milan Kundera. L'être en relation, comme point focal de la dissidence littéraire; les thèmes du désir et de l'exclusion, comme enjeux pivots dans les textes sur la violence contemporaine; les savoirs et les pouvoirs du discours littéraire sur l'anthropologie de la violence, comme éclairage aux résurgences victimaires actuelles: nos trois hypothèses auront permis de multiplier les analyses sur les dynamiques conflictuelles dans les romans à l'étude en empruntant une approche méthodologique centrée sur les enjeux de victimes émissaires et de discours victimisateurs (René Girard). Qui sont les victimes dans les textes? Quels sont les discours qui viennent soutenir ou pourfendre leur victimisation, en plus d'approfondir la réflexion sur la violence? Telles étaient les questions fondamentales à poser afin d'aborder des oeuvres de Frédéric Beigbeder, Marie-Claire Blais, Gil Courtemanche, Yasmina Khadra, Ahmadou Kourouma, Jean-Luc Raharimanana et de Véronique Tadjo, dans notre approche qui transcende frontières et discours nationaux pour aller au plus clair de la difficulté et de la possibilité de l'être-ensemble. Du génocide des Tutsis au Rwanda de 1994 aux actuels attentats terroristes, la pensée des écrivains sur les violences des douze dernières années jette un éclairage essentiel fait de curiosité, de doute, de lucidité, d'ambiguité et d'ironie, où la rencontre avec l'être humain et le monde est encore possible: un bastion plus sur contre la spirale ascendante des violences?
