Authors: Turgeon Lyse , Goulet Julie , Plusquellec Pierrich , Lévesque Jonathan , Nault-Brière Frédéric 
Published: May 2023

L’objectif de cette étude est de documenter l’évolution de la santé psychologique d’étudiantes en psychoéducation durant la crise liée à la COVID-19. Cent cinquante-neuf étudiantes de psychoéducation (90 % de femmes), sélectionnées à partir d’un échantillon plus vaste de 876 étudiantes, ont rempli des questionnaires à deux temps de mesure : avant la COVID-19 en octobre 2019 (Temps 1) et durant la COVID-19 en janvier 2021 (Temps 2). Les questionnaires portaient notamment sur la dépression, l’anxiété, le stress, le soutien social, les stratégies d’adaptation, la connaissance et l’utilisation des services de soutien psychologique sur le campus et les événements de vie stressants. Les données montrent que la pandémie liée à la COVID-19 n’a pas affecté toutes les étudiantes de la même façon. Les étudiantes de premier cycle et celles qui utilisaient davantage des stratégies d’adaptation comme l’évitement ou les attributions auto-accusatrices avant cette crise ont vu une détérioration de leur santé psychologique pendant la crise. Les étudiantes de maîtrise, celles qui utilisaient des stratégies d’adaptation centrées sur le problème et celles qui bénéficiaient d’un bon soutien de la part des membres de leurs familles avant la crise ont plutôt vu une amélioration de leur santé psychologique. Des pistes de solution sont présentées pour améliorer le bien-être étudiant.

Published: May 2023

The maritime industry and port sector are catalysts of economic growth and development of countries. However, they can generate significant environmental and social impacts on marine ecosystems and neighbouring communities. The sustainable development goals (SDGs) proposed by the United Nations (UN) make up the 2030 Agenda and suggest a global sustainable development that needs the collaboration of various stakeholders. In this context, the article aims to identify the SDGs most evidenced in the maritime industry and port sector from a systematic literature review using the tools EndNote, IRaMuTeQ and VOSviewer. The results pointed to SDG 9 Industry, Innovation and Infrastructure, 13 Action against Climate Change and 14 Life on the Water as the most addressed by the studies, highlighting the guidance of the maritime industry and the port sector in contributing to sustainable development based on concern for the marine environment and climate change. It was observed that the studies identified the relevance of contributing to the SDGs. On the other hand, the practical applications were not properly described, thus making it difficult to understand the priority actions for an effective contribution to the SDGs.

Published: May 2023

Knowledge management is recognized as an important tool for sustaining competitive merit and improving performance of work. It is a means through which law firms can clout their knowledge base and intensify work performance. The assessment of knowledge management performance has become increasingly invaluable since it provides the indicator for guiding organizations to improve their work execution and competitiveness. Many law firms have no documented and planned approach to tap the organization’s knowledge and make it accessible to the staff for enhancement of service delivery.
The study was informed by the learning organization theory. The research design for this study was a descriptive and positivism case study that was analysed largely through quantitative methods with a small qualitative component. Purposive sampling design was employed to select 222 law firms, qualitative data was collected using focus group discussions from 12 key informants supported by document review. The results revealed that most of the respondents 86.5% were aware of knowledge management whereas 64.9% indicated that knowledge management contributed to their law firm’s legal practice. From the inferential statistics analysis, there was a significant relationship and influence across different attributes examined that knowledge management is a tool for improving work performance which is, p<0.05. This was also reflected in focus group discussion results.
Awareness of knowledge management and contribution of knowledge management to legal practise were significant tools for improving work performance. The study recommended awareness forums for knowledge management.

ImportancePractice patterns of hydroxychloroquine retinopathy screening have not yet been reported at a national level in South Korea.ObjectiveTo investigate the practice patterns of timing and modality for hydroxychloroquine retinopathy screening in South Korea.Design, Setting, and ParticipantsThis nationwide population-based cohort study of patients in South Korea used data from the national Health Insurance Review and Assessment database. Patients at risk were identified as those who had initiated hydroxychloroquine therapy between January 1, 2009, and December 31, 2020, and used it for 6 months or more. Patients were excluded if they underwent any of the 4 screening modalities recommended by the American Academy of Ophthalmology (AAO) for other ophthalmic diseases prior to hydroxychloroquine use. The timing and modalities of screening used in baseline and monitoring examinations were assessed between January 1, 2015, and December 31, 2021, among patients at risk and long-term (≥5 years) users.ExposureAdherence of baseline screening practices to the 2016 AAO recommendations (fundus examination within 1 year of drug use) was evaluated; adherence of monitoring examinations in year 5 was classified as appropriate (≥2 tests recommended by the AAO), unscreened (no test performed), and underscreened (insufficient number of tests).Main Outcomes and MeasuresTiming of screening and modalities used at baseline and monitoring examinations.ResultsA total of 65 406 patients at risk (mean [SD] age, 53.0 [15.5] years; 50 622 women [77.4%]) were included; 29 776 patients were long-term users (mean [SD] age, 50.1 [14.7] years; 24 898 women [83.6%]). Baseline screening was performed for 20.8% of the patients within 1 year, with a gradual increase from 16.6% in 2015 to 25.6% in 2021. Monitoring examinations, mostly using optical coherence tomography and/or visual field tests, were performed for only 13.5% of the long-term users in year 5 and for 31.6% of the long-term users after 5 years. Appropriate monitoring was performed for less than 10% of long-term users each year from 2015 to 2021; however, the percentage gradually increased over time. The percentage of patients undergoing any monitoring examination in year 5 was 2.3 times greater for those who had received baseline screening than for those who did not (27.4% vs 11.9%; P &amp;lt; .001).Conclusions and RelevanceThis study suggests there is an improving trend in retinopathy screening among hydroxychloroquine users in South Korea; however, most long-term users remained unscreened after 5 years of use. Baseline screening may be useful in reducing the number of unscreened long-term users.

Published: May 2023

AbstractIn this paper, the finite‐time adaptive fuzzy tracking control issue for stochastic nonlinear systems with time‐delay via output‐feedback is studied. Firstly, a state observer and fuzzy logic systems with infinite approximation capability are utilized to estimate the unmeasured states and identify unknown nonlinear characteristics, respectively. Then, a finite‐time adaptive fuzzy tracking controller is devised by the backstepping technology. It is shown that the presented control scheme can ensure the finite‐time square stability of the stochastic nonlinear systems with time‐delay, that is, the output tracking error converges to a sufficiently small neighborhood around the origin in finite‐time, and all signals of the closed‐loop system are bounded. Finally, the effectiveness of the presented control strategy is illustrated via two simulation examples.
Model following adaptive control for the complex dynamic network with the dynamic matrix‐relation links
Authors: Li Xiaoxiao , Wang Yinhe , Li Shengping 
Published: May 2023

SummaryThis article formulates and solves a problem of model following adaptive control (MFAC) of nodes in the complex dynamic network (CDN) with the dynamic matrix‐relation links. From the perspective of composite systems, the CDN with the dynamic matrix‐relation links is considered as an interconnected system composed of intercoupling node subsystem (NS) and link subsystem (LS). Based on this idea, employing the Riccati matrix differential equation as the dynamic equation of LS, and the vector differential equation with the second derivative term as the dynamic equation of NS. Then, to remove the restriction that the state of LS is unavailable, an adaptive control scheme is proposed for NS with the help of constructed dynamic auxiliary tracking target for LS, such that the problem of MFAC of nodes is solved. Besides, it is proved mathematically that the state of NS is asymptotically tracking the state of the given reference model when the state of LS is asymptotically tracking the constructed dynamic auxiliary tracking target. Finally, the numerical simulation is given to verify the effectiveness of the theoretical results in this article.

AbstractSurface chemistry and interlayer engineering determines the electrical properties of 2D MXene. However, it remains challenging to regulate the surface and interfacial chemistry of MXene simultaneously. Herein, simultaneous modulation of Ti3C2Tx MXene surface termination and layer spacing by alkali treatment are achieved. The electrical and electromagnetic properties of Ti3C2Tx are investigated in detail with respect to KOH and ammonia concentration dependence. A high concentration of KOH caused the Ti3C2Tx layer spacing to expand to 13.7 Å and the surface O/F ratio to increase to 33.84. Because of its weaker ionization effect, ammonia provides finer tuning compared to the drastic intercalation of KOH with a thorough sweeping of the F‐containing groups. Ti3C2Tx is enriched with conductive ‐OH termination after ammonia treatment, which achieves an effective balance with the increased interlayer resistance. Therefore, NH3H2O‐Ti3C2Tx achieves broad‐band impedance matching and exhibits an efficient microwave loss of −49.1 dB at a low thickness of 1.7 mm, with an effective frequency bandwidth of 3.9 GHz. The results herein optimize the electrical properties of Ti3C2Tx using surface and interfacial chemistry to achieve broad microwave absorption, providing a framework for enhancing the electromagnetic wave loss of intrinsic MXene.

Published: May 2023

AbstractLithium‐sulfur batteries (LSBs) suffer from uncontrollable shuttling behavior of lithium polysulfides (LiPSs: Li2Sx, 4 ≤ x ≤8) and the sluggish reaction kinetics of bidirectional liquid‐solid transformations, which are commonly coped through a comprehensive adsorption‐catalysis strategy. Herein, a unique FeNV pre‐coordination is introduced to regulate the content of “dissociative Fe3+” in liquid phase, realizing the successful construction of N‐doped micro‐mesoporous “urchin‐like” hollow carbon nanospheres decorated with single atom Fe‐N4 sites and VN nanoparticles (denoted as SA‐Fe/VN@NMC). The strong chemisorption ability toward LiPSs and catalyzed Li2S decomposition behavior on VN, along with the boosted reaction kinetics for sulfur reduction on SA‐Fe sites are experimentally and theoretically evidenced. Moreover, the nanoscale‐neighborhood distribution of VN and SA‐Fe active sites presents synergistic effect for the anchoring‐reduction‐decomposition process of sulfur species. Thus SA‐Fe/VN@NMC presents an optimized adsorption‐catalysis effect for the whole sulfur conversion. Therefore, the SA‐Fe/VN@NMC based Li‐S cells exhibit high cyclic stability (a low decay of 0.024% per cycle over 700 cycles at 1 C, sulfur content: 70 wt%) and considerable rate performance (683.2 mAh g−1 at 4 C). Besides, a high areal capacity of 5.06 mAh cm−2 is retained after 100 cycles under the high sulfur loading of 5.6 mg cm−2. This work provides a new perspective to design the integrated electrocatalysts comprising hetero‐formed bimetals in LSBs.
Does Water‐in‐Salt Electrolyte Subdue Issues of Zn Batteries?
Authors: Khan Ziyauddin , Kumar Divyaratan , Crispin Xavier 
Published: May 2023

AbstractZn‐metal batteries (ZnBs) are safe and sustainable because of their operability in aqueous electrolytes, abundance of Zn, and recyclability. However, the thermodynamic instability of Zn metal in aqueous electrolytes is a major bottleneck for its commercialization. As such, Zn deposition (Zn2+ → Zn(s)) is continuously accompanied by the hydrogen evolution reaction (HER) (2H+ → H2) and dendritic growth that further accentuate the HER. Consequently, the local pH around the Zn electrode increases and promotes the formation of inactive and/or poorly conductive Zn passivation species (Zn + 2H2O → Zn(OH)2 + H2) on the Zn. This aggravates the consumption of Zn and electrolyte and degrades the performance of ZnB. To propel HER beyond its thermodynamic potential (0 V vs standard hydrogen electrode (SHE) at pH 0), the concept of water‐in‐salt‐electrolyte (WISE) has been employed in ZnBs. Since the publication of the first article on WISE for ZnB in 2016, this research area has progressed continuously. Here, an overview and discussion on this promising research direction for accelerating the maturity of ZnBs is provided. The review briefly describes the current issues with conventional aqueous electrolyte in ZnBs, including a historic overview and basic understanding of WISE. Furthermore, the application scenarios of WISE in ZnBs are detailed, with the description of various key mechanisms (e.g., side reactions, Zn electrodeposition, anions or cations intercalation in metal oxide or graphite, and ion transport at low temperature).

Published: May 2023

AbstractPerovskite solar cells (PSCs) show great promise for next‐generation building‐integrated photovoltaic (BIPV) applications because of their abundance of raw materials, adjustable transparency, and cost‐effective printable processing. Owing to the complex perovskite nucleation and growth control, the fabrication of large‐area perovskite films for high‐performance printed PSCs is still under active investigation. Herein, the study proposes an intermediate‐phase‐transition‐assisted one‐step blade coating for an intrinsic transparent formamidinium lead bromide (FAPbBr3) perovskite film. The intermediate complex optimizes the crystal growth path of FAPbBr3, resulting in a large‐area, homogeneous, and dense absorber film. A champion efficiency of 10.86% with high open‐circuit voltage up to 1.57 V is obtained with a simplified device architecture of glass/FTO/SnO2/FAPbBr3/carbon. Moreover, the unencapsulated devices maintain 90% of their initial power conversion efficiency after aging at 75 °C for 1000 h in ambient air, and 96% after maximum power point tracking for 500 h. The printed semitransparent PSCs, with average visible light transmittance over 45%, demonstrate high efficiencies for both small devices (8.6%) and 10 × 10 cm2 modules (5.55%). Finally, the ability to customize the color, transparency, and thermal insulation properties of FAPbBr3 PSCs makes them high prospects as multifunctional BIPVs.

Published: May 2023

AbstractMultifunctional selectivity and mechanical properties are always a focus of attention in the field of flexible sensors. In particular, the construction of biomimetic architecture for sensing materials can endow the fabricated sensors with intrinsic response features and extra‐derived functions. Here, inspired by the asymmetric structural features of human skin, a novel tannic acid (TA)‐modified MXene‐polyurethane film with a bionic Janus architecture is proposed, which is prepared by gravity‐driven self‐assembly for the gradient dispersion of 2D TA@MXene nanosheets into a PU network. This obtained film reveals strong mechanical properties of a superior elongation at a break of 2056.67% and an ultimate tensile strength of 50.78 MPa with self‐healing performance. Moreover, the Janus architecture can lead to a selective multifunctional response of flexible sensors to directional bending, pressure, and stretching. Combined with a machine learning module, the sensor is endowed with high recognition rates for force detection (96.1%). Meanwhile, direction identification in rescue operations and human movement monitoring can be realized by this sensor. This work offers essential research value and practical significance for the material structures, mechanical properties, and application platforms of flexible sensors.
