L’agentivité des jeunes exposés à la violence
conjugale soutenue par la méthode du calendrier historique de vie
Authors: Dumont Annie , Lessard Geneviève , Alvarez-Lizotte Pamela , Pellerin Anaïs , Lapierre Simon 
Published: April 2023

Cadre de la recherche : Cet article s’appuie
sur deux études menées auprès de jeunes adultes ayant vécu l’exposition à la violence
conjugale (EVC) dans l’enfance ou l’adolescence. Ces études s’intéressaient à leur
parcours de vie et au regard qu’ils portaient sur la violence conjugale.

Objectifs : L’article documente les types
d’agentivité mis en œuvre par les jeunes interrogés, à travers leur parcours de vie. Il
explore aussi dans quelle mesure l’utilisation du calendrier historique de vie (CHV) dans
la recherche peut favoriser la reprise de pouvoir de ces jeunes sur la manière de raconter
leur histoire.

Méthodologie : Des entrevues qualitatives
semi-dirigées, soutenues par le CHV, ont été réalisées avec 63 jeunes de 18 à 25 ans ayant
été exposés à la violence conjugale. L’analyse de leur agentivité s’est faite à partir de
la typologie d’Hitlin et Elder (2007).

Résultats : Les stratégies d’agentivité
identitaire décrites par les participants se rapportent beaucoup aux actions les aidant à
se protéger de la violence dans leur quotidien. Les stratégies d’agentivité pragmatique et
du parcours de vie leur permettent quant à elles de faire face à des situations nouvelles
et à se projeter dans un avenir meilleur. Leur participation à la recherche fait partie de
leurs stratégies agentives.

Conclusions : Le regard rétrospectif adopté par
les participants les amène à décrire le sens qu’ils donnent aux stratégies agentives
utilisées pour contrer l’expérience d’EVC et ses conséquences à court et à long terme. En
plus de générer de nouvelles connaissances sur l’EVC, la méthodologie de l’étude favorise
une réappropriation de leur récit de vie par les jeunes concernés, qui peuvent expliquer
le sens de leurs actions ou décisions.

Contribution : Le fait de
considérer les jeunes ayant vécu l’EVC comme des acteurs de leur parcours de vie contribue
à leur donner une voix et à prendre en compte leur point de vue dans les décisions qui les
concernent.
Identités fantômes : communautés et patrimoine territorial en Acadie du Nouveau-Brunswick
Authors: Wade Mathieu 
Published: April 2023

L’Acadie ne possède pas d’État propre, mais elle occupe des territoires. Pendant près de deux siècles, de la seconde moitié du 18e siècle aux années 1930, des centaines de localités acadiennes ont été établies dans les provinces maritimes et tout particulièrement au Nouveau-Brunswick. Ces localités ont historiquement délimité les frontières de la communauté ethnolinguistique acadienne et se sont explicitement inscrites dans le projet nationaliste de la seconde moitié du 19e siècle. Or, à partir des années 1950, le modèle territorial acadien est entré en crise et on a assisté à une désinstitutionnalisation des communautés. Cet article porte sur les transformations de l’ancrage territorial en retraçant la dynamique de peuplement et en interrogeant la persistance de frontières locales dans un contexte où elles ne renvoient plus à des communautés vivantes. Pour ce faire, nous proposons une lecture critique du patrimoine local à partir d’une analyse des monographies paroissiales et de la morphologie des communautés.
Le modelé d’érosion glaciaire de l’île d’Anticosti révélé par l’imagerie LiDAR
Authors: Hétu Bernard , Bernatchez Pascal , Dubé Jérôme 
Published: April 2023

Des images LiDAR à haute résolution dévoilent des modelés d’érosion glaciaire inédits qui nuancent fortement les interprétations publiées antérieurement concernant l’histoire glaciaire de l’île d’Anticosti. Sculptées dans le roc, ces formes d’érosion glaciaire sont très diversifiées : lacs de surcreusement glaciaire, drumlins rocheux, cannelures géantes, mégaqueues-de-rat, dalles de roc déplacées par les glaciers. Bien que pour la plupart discrètes, ces formes d’érosion glaciaire sont présentes partout sur l’île. Toutefois, c’est dans les basses terres de l’est et de l’ouest que l’empreinte glaciaire est la plus forte. Dans les basses terres de l’est, l’écoulement glaciaire vers le sud-ouest, observé partout sur l’île, a été suivi par un écoulement vers le sud-est. Ces 2 écoulements avaient leur source sur le Bouclier canadien (inlandsis laurentidien). Un écoulement tardif vers le nord a été observé dans la moitié nord du plateau central (au nord de la rivière Jupiter). Cet écoulement vers le nord est attribué à la calotte glaciaire régionale qui a occupé le plateau central durant la déglaciation.
La face cachée des plaidoyers de culpabilité négociés par des entreprises : l’exemple de l’affaire R c SNC-Lavalin
Authors: Manirabona Amissi M , Masson Flavie 
Published: April 2023

Dans le présent article, nous nous penchons sur les difficultés découlant des plaidoyers de culpabilité négociés par les entreprises et enregistrés devant les juridictions criminelles canadiennes. Nous partons de la décision relative au plaidoyer de culpabilité survenu en décembre 2019 entre le ministère public canadien (la Couronne) et la société d’ingénierie montréalaise SNC-Lavalin Construction inc, une filiale du Groupe SNC-Lavalin inc. À cet effet, le texte s’attarde sur les circonstances qui ont entouré ce plaidoyer de culpabilité par cette filiale pour résoudre l’affaire pénale contre la firme d’ingénierie, ainsi que sur les conséquences négatives qui pourraient en découler. De manière plus générale, les problématiques associées aux plaidoyers de culpabilité impliquant les entreprises sont également examinées.
Turkey vs Egypt in the Eastern Mediterranean
Authors: Parlanova Aila Telman kyzy 
Published: April 2023

The object of the study is Ankara's foreign policy strategy. The subject of the study is the positions of Turkey and Egypt in the Eastern Mediterranean region. The aim is to identify the possibility of a Turkish–Egyptian alliance in the region after the extremely tense relations recorded since 2013, the establishment in Egypt of a new president A.F. Al-Sisi, the ideological antipode of R.T. Erdogan. The relevance of the study is evidenced by changes in the rhetoric of Turkey's top officials and the demonstration of readiness to build a dialogue with Cairo. Particular attention is paid to Ankara's position on the establishment of maritime borders in the Aegean and Mediterranean Seas on the basis of bilateral agreements. Research methods: analysis of strategies, official documents, logical-heuristic and system methods, as well as analysis of political events in the region. Based on the analysis of primary sources (foreign policy strategies 2020-2023), it was revealed: since 2020, the Eastern Mediterranean region has been the main vector of Ankara's foreign policy. As noted in the reports of the Ministry of Energy and Mineral Resources, the country is 70% dependent on foreign energy supplies, which explains Ankara's uncompromising position on securing its right to extract gas from the depths of the Eastern Mediterranean. Attempts to restore relations with Egypt are a geopolitical necessity. However, Cairo found itself in the position of Turkey's competitor in an effort to turn into an energy hub when exporting gas from Israel to Europe. Egypt attaches paramount importance to the issue of energy security, which is confirmed by the Egypt Vision 2030 strategy. The most advantageous for Egypt is the preservation of the Egypt-Israel-Greece-Cyprus block. Based on the conducted research, it can be concluded that there is an extremely low probability of a Turkish-Egyptian rapprochement. The findings of the study can be taken into account when studying and forecasting Turkey's foreign policy.

AbstractPurposeTo define an optimal set of b‐values for accurate derivation of diffusion MRI parameters in the brain with segmented Intravoxel Incoherent Motion (IVIM) model.MethodsSimulations of diffusion signals were performed to define an optimal set of b‐values targeting different perfusion regimes, by relying on an optimization procedure which minimizes the total relative error on estimated IVIM parameters computed with a segmented fitting procedure. Then, the optimal b‐values set was acquired in vivo on healthy subjects and skull base chordoma patients to compare the optimized protocol with a clinical one.ResultsThe total relative error on simulations decreased of about 40% when adopting the optimal set of 13 b‐values (0 10 20 40 50 60 200 300 400 1200 1300 1400 1500 s/mm2), showing significant differences and increased precision on D and f estimates with respect to simulations with a non‐optimized b‐values set. Similarly, in vivo acquisitions demonstrated a dependency of IVIM parameters on the b‐values array, with differences between the optimal set of b‐values and a clinical non‐optimized acquisition. IVIM parameters were compatible to literature values, with D (0.679/0.701 [0.022/0.008] ·10−3mm2/s), f (5.49/5.80 [0.70/1.14] %), and D* (8.25/7.67 [0.92/0.83] ·10−3mm2/s) median [interquartile range] estimates for white matter/gray matter in volunteers and D (0.709/0.715/1.06 [0.035/0.023/0.271] ·10−3mm2/s), f (7.08/7.84/21.54 [1.20/1.06/6.05] %), and D* (10.85/11.84/2.32 [1.38/2.32/4.94] ·10−3mm2/s) for white matter/gray matter/Gross Tumor Volume in patients with skull‐base chordoma tumor.ConclusionsThe definition of an optimal b‐values set can improve the estimation of quantitative IVIM parameters. This allows setting up an optimized approach that can be adopted for IVIM studies in the brain.
IMRT QA result prediction via MLC transmission decomposition

Published: April 2023

AbstractBackgroundQuality assurance measurement of IMRT/VMAT treatment plans is resource intensive, and other more efficient methods to achieve the same confidence are desirable.PurposeWe aimed to analyze treatment plans in the context of the treatment planning systems that created them, in order to predict which ones will fail a standard quality assurance measurement. To do so, we sought to create a tool external to the treatment planning system that could analyze a set of MLC positions and provide information that could be used to calculate various evaluation metrics.MethodsThe tool was created in Python to read in DICOM plan files and determine the beam fluence fraction incident on each of seven different zones, each classified based on the RayStation MLC model. The fractions, termed grid point fractions, were validated by analyzing simple test plans. The average grid point fractions, over all control points for 46 plans were then computed. These values were then compared with gamma analysis pass percentages and median dose differences to determine if any significant correlations existed.ResultsSignificant correlation was found between the grid point fraction metrics and median dose differences, but not with gamma analysis pass percentages. Correlations were positive or negative, suggesting differing model parameter value sensitivities, as well as potential insight into the treatment planning system dose model.ConclusionsBy decomposing MLC control points into different transmission zones, it is possible to create a metric that predicts whether the analyzed plan will pass a quality assurance measurement from a dose calculation accuracy standpoint. The tool and metrics developed in this work have potential applications in comparing clinical beam models or identifying their weak points. Implementing the tool within a treatment planning system would also provide more potential plan optimization parameters.
Sound source localization model of cube microphone array
Authors: Li Minzong , Wang Simeng , Tian Zhongxu 
Published: April 2023

AbstractThis paper conducts in‐depth research on the sound source localization technology of the microphone array and designs a sound source localization system based on the cube microphone array. Firstly, the sound source localization model is established using the cube microphone array combined with the spherical near‐field acoustic holography. Secondly, the numerical and sound source localization simulations are carried out using the spherical wave. Finally, the simulation and experiment of sound source location for sound at 100, 1000, and 2000 Hz are carried out using the model. Both simulation and experimental results show that when the sound source frequency is 100 and 1000 Hz, the location of the sound source can be accurately located by using the sound source localization model of a cube microphone array, and the sound field reconstruction error is low. When the sound source frequency is 2000 Hz, the location of the sound source cannot be located, and the sound field reconstruction error is very high, which will cause the misjudgment of the sound source location.

Published: April 2023

AbstractThe development of a novel reactive spray technology based on the well‐known gas‐phase metal oxide synthesis route provides innumerable opportunities for the production of non‐oxide nanoparticles. Among these materials, metal sulfides are expected to have a high impact, especially in the development of electrochemical and photochemical high‐surface‐area materials. As a proof‐of‐principle, MnS, CoS, Cu2S, ZnS, Ag2S, In2S3, SnS, and Bi2S3 are synthesized in an O2‐lean and sulfur‐rich environment. In addition, the formation of Cu2S in a single‐droplet combustion experiment is reported. The multiscale approach combining flame sprays with single‐droplet combustion is expected to pave the way toward a fundamental understanding of the gas‐phase formation of metal sulfides in the future. The knowledge acquired can open the possibility for the development of a next‐generation gas‐phase technology facilitating the scalable synthesis of functional binary/ternary metal sulfides.

Published: April 2023

AbstractThe embrittlement of metallic alloys by liquid metals leads to catastrophic material failure and severely impacts their structural integrity. The weakening of grain boundaries (GBs) by the ingress of liquid metal and preceding segregation in the solid are thought to promote early fracture. However, the potential of balancing between the segregation of cohesion‐enhancing interstitial solutes and embrittling elements inducing GB de‐cohesion is not understood. Here, the mechanisms of how boron segregation mitigates the detrimental effects of the prime embrittler, zinc, in a Σ5 [001] tilt GB in α‐Fe (4 at.% Al) is unveiled. Zinc forms nanoscale segregation patterns inducing structurally and compositionally complex GB states. Ab initio simulations reveal that boron hinders zinc segregation and compensates for the zinc‐induced loss in GB cohesion. The work sheds new light on how interstitial solutes intimately modify GBs, thereby opening pathways to use them as dopants for preventing disastrous material failure.
Multi‐Stimuli‐Responsive and Mechano‐Actuated Biomimetic Membrane Nanopores Self‐Assembled from DNA

Published: April 2023

AbstractIn bioinspired design, biological templates are mimicked in structure and function by highly controllable synthetic means. Of interest are static barrel‐like nanopores that enable molecular transport across membranes for use in biosensing, sequencing, and biotechnology. However, biological ion channels offer additional functions such as dynamic changes of the entire pore shape between open and closed states, and triggering of dynamic processes with biochemical and physical stimuli. To better capture this complexity, this report presents multi‐stimuli and mechano‐responsive biomimetic nanopores which are created with DNA nanotechnology. The nanopores switch between open and closed states, whereby specific binding of DNA and protein molecules as stimuli locks the pores in the open state. Furthermore, the physical stimulus of high transmembrane voltage switches the pores into a closed state. In addition, the pore diameters are larger and more tunable than those of natural templates. These multi‐stimuli‐responsive and mechanically actuated nanopores mimic several aspects of complex biological channels yet offer easier control over pore size, shape and stimulus response. The designer pores are expected to be applied in biosensing and synthetic biology.
Reversing Acute Kidney Injury through Coordinated Interplay of Anti‐Inflammation and Iron Supplementation

Published: April 2023

AbstractAcute kidney injury (AKI) induced by ischemia reperfusion is closely related to mitochondrial dysfunction. Nicotinamide adenine dinucleotide (NAD+) can enhance the mitochondrial function and restrain the following inflammation, but it is hardly delivered and lacks renal targeting ability. To address these problems, herein, an ultrasmall Fe3O4 nanoparticle is used as a carrier to deliver nicotinamide mononucleotide (NMN), a precursor of NAD+. An outstanding sophistication of the current design is that once NMN is attached on the surface of Fe3O4 nanoparticles through its phosphate group, the remaining part is structurally highly similar to nicotinamide riboside, which provides an opportunity to deliver the NAD+ precursor into renal cells through nicotinamide riboside kinase 1 on the cell membrane. It is demonstrated that NMN‐loaded Fe3O4 nanoparticles can effectively reverse AKI induced by ischemia reperfusion. In‐depth studies indicate that a well‐timed iron replenishment following anti‐inflammation treatment plays a determined role in recovering AKI, which distinguishes the current study from previous strategies centering on anti‐ROS (reactive oxygen species), anti‐inflammation, or even iron elimination.
Defect‐Enriched Hollow Porous Carbon Nanocages Enable Highly Efficient Chlorine Evolution Reaction

Published: April 2023

AbstractMetal‐free carbon‐based catalysts are crucial for the electrocatalytic chlorine evolution reaction (CER) to reduce the usage of noble metals and industrial cost. However, the corresponding catalytic activity of high overpotential and low durability hinders their wide application. Here, a hollow porous carbon (HPC) nanocage with a controlled oxygen electronic state around designed carbon defects for CER activity is reported. Alkali etching can bring defects in zeolite with a hollow structure. In a hard template strategy, the type of carbon defects is directly related to etching degree of the zeolite template. More importantly, the oxygen atoms can be “borrowed” from the zeolite framework by the defective carbon. The electron density around unsaturated O atoms can be decreased on the minor defects in carbon compared with that on large defects which is favorable for the adsorption of Cl−. Consequently, the as‐synthesized HPC nanocages with minor defects show excellent electrocatalytic performance for CER with a low overpotential of 94 mV at current density of 10 mA cm−2with good stability, which is superior to the commercial precious metal catalyst of dimensionally stable anode (DSA), and the best in the reported carbon materials. The designed carbon materials provide an option for metal‐free industrial catalysts with significant CER activities.

Published: April 2023

AbstractThe tailoring of the charge transfer between support material and transition metal active phase is an effective strategy for fine tuning the electronic structure of the catalyst active site, and hence improving the activity and stability of the reaction. This works presents that Co nanoparticles supported on N‐doped mesoporous hollow carbon nanospheres (Co/NMHCS) decouple the effect of electronic structure on catalytic performance. The detailed experimental and theoretical results reveal the charge distribution at the Co/NMHCS interface due to N‐doped MHCS. With tuning the electron redistribution, the interface between Co nanoparticles and NMHCS as the active site shows the strong capability to adsorb and reduce the OOH* and proton, thus leading to the optimal ORR, OER, and HER activity in Co/NMHCS. Furthermore, Co/NMHCS‐based Zn–air battery exhibits high power density of 185 mW cm−2, and high gravimetric energy density of 753 mAh gZn−1. Density functional theory (DFT) reveals the electrons accumulate directly on the NMHCS support, which originates from an interplay between Co nanoparticles and the NMHCS support. This work provides constructive guidance for precisely regulating the interface electronic structures to achieve excellent electrocatalytic performance.
Bio‐Inspired Instability‐Induced Hierarchical Patterns Having Tunable Anisotropic Wetting Properties

Published: April 2023

AbstractThis paper introduces a method for the bottom‐up fabrication of bio‐inspired hierarchical patterns having tunable anisotropic wetting properties. The method exploits the surface instability of bilayers comprising a gold nanofilm attached to a substantially prestretched elastomer substrate. Upon film formation, highly aligned wrinkles spontaneously form on the surface owing to the surface instability driven by the compressive residual stress in the film. Thereafter, uniaxial compressive strain is applied to the film by prestretch relaxation of the substrate, which generates an array of high‐aspect‐ratio ridges on the surface. Consequently, hierarchical patterns comprising unidirectionally aligned ridges covered with wrinkles are obtained. Water droplets placed on surfaces having the aforementioned hierarchical patterns show direction‐dependent contact angles, resulting in elongated shapes, which indicates the presence of anisotropic wetting properties. The magnitude of wetting anisotropy can be tuned by simple control of the applied compressive strain and film thickness.
