Le processus de révision et l'écriture informatisée – Description des utilisations du traitement de texte par des élèves du secondaire au Québec
Authors: Grégoire Pascal , Karsenti Thierry 
Published: April 2013

Les TIC modifient substantiellement l'acte scriptural : en influençant les processus cognitifs chez les scripteurs, elles libèrent des ressources cognitives (Daiute, 1983 ; Jonassen, 1999). Pourtant, malgré cette influence, les scripteurs informatisés se contentent souvent d'apporter des modifications de surface à leurs textes (Faigley & Witte, 1981 ; Figueredo & Varnhagen, 2006). Nous avons donc voulu décrire comment les TIC interviennent réellement dans le processus cognitif de révision. Pour y parvenir, nous avons procédé selon une approche qualitative, fondée sur l'observation de scripteurs informatisés (N = 11). Nous avons analysé le type d'interaction qu'ils entretiennent avec le correcteur d'orthographe ; de plus, nous avons analysé les verbalisations concurrentes à la tâche ainsi qu'une série d'entrevues de groupe. De façon générale, nous avons constaté une utilisation somme toute limitée des outils informatiques, que les scripteurs n'arrivent pas à exploiter pleinement. Le manque d'habiletés au clavier et au traitement de texte pourrait constituer une entrave à une utilisation plus rentable des TIC.

A autonomia científica e tecnológica de um país pressupõe que o mesmo tenha uma educação de qualidade. O objetivo deste artigo é apresentar um instrumento de medida de avaliação da resistência à mudança na administração da educação superior. Propõe-se um desenho e operacionalização para o projeto Mapa Estratégico da Educação Superior (MEES) fundamentado em um sistema de gestão integrado. O MEES se constitui em uma proposta metodológica para a operacionalização do Plano de Desenvolvimento Institucional (PDI) em Instituições de Ensino Superior (IES). O instrumento de medida de avaliação da resistência à mudança na administração da educação superior (RAMES) se fundamenta na seguinte base conceitual: teoria de resposta ao ítem (TRI), teoria psicometrica e no estudo sobre gestão da mudança. A RAMES compõe-se de cinco etapas: 1. elaboração do instrumento de coleta de dados; 2. definição do tamanho amostra representativa da comunidade acadêmica das IES; 3. coleta de dados – conjunto de itens; 4. estimação dos parâmetros dos itens; 5. definição da escala de medida A RAMES tem como expectativa de resultados contribuir para a eficácia na implementação do MEES. Visa também identificar os principais indicadores de resistência a mudança na administração da educação superior.
What Zora Knew: A Crossroads, a Bargain with the Devil, and a Late Witness
Authors: Lawless Elaine J. 
Published: April 2013

Abstract
This tribute to Zora Neale Hurston is meant to re-introduce Hurston’s work to folklorists and Hurston enthusiasts who already know her and some of her work, yet who may not have thought much about her more recently. I have gained new regard, respect, and passion for what Hurston brought to ethnographic research, to the art of writing about folklore and Southern black life. She modeled the creative impulse in many different and overlapping genres, while always serving as a model for staying true to one’s own personal politics in the midst of tremendous racism, sexism, classism, and academic elitism and disciplinary conservatism. Our appreciation for Hurston keeps her alive in our imaginations, and the folklore we share about her and her life is a testament to our continued interest in both her personal and professional life.
Raising the Quality of Care During Medical Missions: A Survey to Assess the Need for Clinical and Anatomic Pathology Services in International Medical Missions
Authors: Naujokas Agne 
Published: April 2013

Context.—Providing basic medical care to patients in underserved communities around the world is a valuable service and should not be compromised. Limited publicly available information on the use of pathology services during short-term medical missions (STMMs) shows a dire need for the improved quality of care being provided.Objective.—To assess the need for clinical and anatomic pathology services in international medical missions by conducting an online survey.Design.—A survey containing 35 questions aimed to understand the current use and availability of routine laboratory tests during STMMs, identify the need for particular tests that would improve quality of care, and determine the perceived obstacles preventing the delivery of the care to underserved communities worldwide. Answers from 21 health care providers who served on 50 medical missions were assessed.Results.—Survey results revealed a significant discrepancy between the availability of pathology services in the United States and during STMMs. Statistical significance (P&lt; .001) was found in areas of routine blood work, cytopathology, and histologic evaluation, among many others. More than half of the STMMs did not have access to basic metabolic panel, rapid hepatitis B test, and microbial cultures. Another 28% of health care providers indicated that having human immunodeficiency virus testing would have improved health care quality.Conclusions.—Survey results show the need for improved pathology support during STMMs. The lack of precise diagnosis and disease monitoring has a negative effect on the quality of care provided during missions and the ability to enhance global health.
Hypoxic Patterns of Placental Injury: A Review
Authors: Stanek Jerzy 
Published: April 2013

Context.—In utero hypoxia is an important cause of perinatal morbidity and mortality and can be evaluated retrospectively to explain perinatal outcomes, to assess recurrence risk in subsequent pregnancies, and to investigate for medicolegal purposes by identification of many hypoxic placental lesions. Definitions of some placental hypoxic lesions have been applied relatively liberally, and many of them are frequently underreported.Objectives.—To present a comprehensive assessment of the criteria for diagnosing acute and chronic histologic features, patterns, and lesions of placental and fetal hypoxia and to discuss clinicopathologic associations and limitations of the use thereof. The significance of lesions that have been described relatively recently and are not yet widely used, such as laminar necrosis; excessive, extravillous trophoblasts; decidual multinucleate extravillous trophoblasts; and, most important, the patterns of diffuse chronic hypoxic preuterine, uterine, and postuterine placental injury and placental maturation defect, will be discussed.Data Sources.—Literature review.Conclusions.—The placenta does not respond in a single way to hypoxia, and various placental hypoxic features should be explained within a clinical context. Because the placenta has a large reserve capacity, hypoxic lesions may not result in poor fetal condition or outcome. On the other hand, very acute, in utero, hypoxic events, followed by prompt delivery, may not be associated with placental pathology, and many poor perinatal outcomes can be explained by an etiology other than hypoxia. Nevertheless, assessment of placental hypoxic lesions is helpful for retrospective explanations of complications in pregnancy and in medicolegal investigation.
A Note on Leigh Hunt, Nicholas Carrington, and The Liberal
Authors: Roe Nicholas 
Published: April 2013

Plymouth poet Nicholas Carrington's poem of bon voyage for Leigh Hunt, 'To a Friend, On His Approaching Voyage to Pisa' (1822), marks the beginning of Hunt's journey to join Lord Byron and P. B. Shelley in publishing the Liberal magazine. The poem offers a sidelight on some iconic events of Anglo-Italian Romanticism, and suggest that Carrington's other works deserve more attention than they have so far received.
Décrire les « Sauvages » : réflexion sur les manières de désigner les autochtones dans le latin des Relations 1
Authors: Gallucci John A. 
Published: April 2013

Cet article propose une étude des termes latins employés par trois jésuites — Pierre Biard, François Ragueneau et Isaac Jogues — pour décrire les « Sauvages ». Reprenant la réflexion proposée par Francis Jennings sur le mot anglais savage, dont le sens a évolué de la « simple sauvagerie » à la « férocité bestiale », l’auteur montre comment l’histoire de ce mot est étroitement liée à la rencontre entre les Amérindiens et les Européens.
La Clinique psychanalytique de Montréal : cinq ans d’existence. Un projet d’engagement social de la psychanalyse et un dispositif d’écoute original
Authors: Lasvergnas Isabelle 
Published: April 2013

Ce texte présente un « état des lieux », après plus de 5 années d’existence, de la Clinique psychanalytique de Montréal (CPM/Centre de consultation de la Société psychanalytique de Montréal). Il vise à rendre compte de la philosophie clinique et théorique qui a sous-tendu le projet dès son origine, faisant de celui-ci non seulement un projet « social », mais au plein sens du terme, un projet de recherche clinique. Corollaire des nouvelles problématiques psychiques rencontrées dans la cure aujourd’hui, en particulier chez les jeunes générations, se pose pour la psychanalyse contemporaine la question d’une nouvelle conjonction entre inconscient et culture, dont une clinique comme la CPM constitue un observatoire privilégié. À titre d’illustration des interrogations de recherche en cours à la Clinique, le texte propose une première réflexion théorique sur le dispositif des entrevues préliminaires mis en place. Il aborde également, les résistances particulières que peut susciter une pratique clinique dans une « institution », en lien avec des points aveugles de la filiation psychanalytique, ses idéologies groupales et une idéalisation de la transmission psychanalytique dans laquelle s’est inscrite, dès les premières années de la découverte, une résistance à la tercéisation.

Published: July 2024

AbstractStretchable devices have gained increasing interest in recent years, particularly in the field of wearable electronics. Among them, fiber‐type devices with high mechanical conformability hold great potential to enable next‐generation wearable and interactive applications with their special structure and high compatibility with the well‐established textile industries. In this study, a hydrogel fiber providing large moisture retention and high mechanical compliance is fabricated, with which a new approach to enable highly stretchable electromechanical sensors based on knot structures is developed. Comparative analysis with common orthogonal textile structures reveal the superior performance of sensors based on ionotronic knots. Stress sensors with the double overhand knot exhibit ≈four times greater variation in capacitance than those with orthogonal structures, and sensors with the clove hitch knot exhibit a fast response time of 57 ms. Based on the characteristics of different knots, a sensor matrix based on clove hitch knots to map the pressure distribution, and a wearable mole code generator based on reef knots to recognize and encode wrist motions are developed. These applications demonstrate the excellent performance of knot‐architecture sensors and their great potential in the fields of smart fabrics and human–machine interactions.
Boric Acid Matrix‐Activated nπ* Transition of Guest Chromophores: from Pure Fluorescence to Efficient Afterglow
Authors: Cao Peisheng , Chen Qian , Wu Peng 
Published: July 2024

AbstractEl‐Sayed rule highlights the important role of heteroatoms (e.g., N, O, and S) and the corresponding nπ* transition in designing efficient organic phosphors. Nevertheless, for some heteroatom‐rich fluorophores, their phosphorescence is quite weak (e.g., fluorescein), since the nπ* components are absent in the whole transitions. Here, these chromophores (mainly with n electron‐containing twisted structure) are found doping into the boric acid (BA) matrix can activate the nπ* transition for efficient afterglow luminescence. For example, doping purely green‐emitting fluorescein into BA yielded a high afterglow quantum yield (≈24%) and a long‐lasting, blue‐shifted cyan afterglow (>10 s). The covalent/non‐covalent interactions between the BA matrix and the guests resulted in twisting the n electron‐containing structure to promote the spin‐orbit coupling process, leading to the generation of new excited state triplet transition pathways. Since the guest chromophores feature visible light absorption, a series of multi‐color afterglow phosphors with visible or white light excitation are successfully constructed.
Cyclization Through Dual C(sp3)−H Functionalization
Authors: Sadeghi Masoud 
Published: July 2024

AbstractC(sp3)−H functionalization methods have been widely employed in many organic transformations such as cyclization reactions, heterocycle synthesis, cross‐coupling protocols, and photochemical transformations. Among these transformations, cyclization reaction through C(sp3)−H functionalization offers a direct route to convert simple linear substrates to complex products. There are three common modes of utilizing C(sp3)−H bonds in cyclization reactions including single, double, and dual C(sp3)−H functionalization. As the most challenging mode, dual C(sp3)−H functionalization refers to converting two separate C(sp3)−H bonds in one molecule into desired C−Z bonds which can be employed in cyclization reactions. Cyclization reaction via dual functionalization of C(sp3)−H bonds can be classified based on the C−H reactivities. Therefore, these reactions can be categorized into three classes based on the types of C(sp3)−H bonds including activated‐activated, activated‐unactivated, and unactivated‐unactivated C(sp3)−H bonds. Most published reports for cyclization reactions through dual C(sp3)−H functionalization involve activated‐activated C(sp3)−H bonds. However, the number of reported papers on the other two classes has been growing. This review focuses on the dual C(sp3)−H functionalization protocols used for cyclization reactions and categorizes the published papers based on the types of C(sp3)−H bonds.

AbstractMulticomponent catalysts can be designed to synergistically combine reaction intermediates at interfacial active sites, but restructuring makes systematic control and understanding of such dynamics challenging. We here unveil how reducibility and mobility of indium oxide species in Ru‐based catalysts crucially control the direct, selective conversion of CO2 to ethanol. When uncontrolled, reduced indium oxide species occupy the Ru surface, leading to deactivation. With the addition of steam as a mild oxidant and using porous polymer layers to control In mobility, Ru−In2O3 interface sites are stabilized, and ethanol can be produced with superior overall selectivity (70 %, rest CO). Our work highlights how engineering of bifunctional active ensembles enables cooperativity and synergy at tailored interfaces, which unlocks unprecedented performance in heterogeneous catalysts.
Frenkel and Charge‐Transfer Excitonic Couplings Strengthened by Thiophene‐Type Solvent Enables Binary Organic Solar Cells with 19.8 % Efficiency

AbstractOvercoming the trade‐off between short‐circuited current (Jsc) and open‐circuited voltage (Voc) is important to achieving high‐efficiency organic solar cells (OSCs). Previous works modulated the energy gap between Frenkel local exciton (LE) and charge‐transfer (CT) exciton, which served as the driving force of exciton splitting. Differently, our current work focuses on the modulation of LE‐CT excitonic coupling (tLE‐CT) via a simple but effective strategy that the 2‐chlorothiophene (2Cl−Th) solvent utilizes in the treatment of OSC active‐layer films. The results of our experimental measurements and theoretical simulations demonstrated that 2Cl−Th solvent initiates tighter intermolecular interactions with non‐fullerene acceptor in comparison with that of traditional chlorobenzene solvent, thus suppressing the acceptor's over‐aggregation and retarding the acceptor crystallization with reduced trap. Critically, the resulting shorter distances between donor and acceptor molecules in the 2Cl−Th treated blend efficiently strengthen tLE‐CT, which not only promotes exciton splitting but also reduces non‐radiative recombination. The champion efficiencies of 19.8 % (small‐area) with superior operational reliability (T80: 586 hours) and 17.0 % (large‐area) were yielded in 2Cl−Th treated cells. This work provided a new insight into modulating the exciton dynamics to overcome the trade‐off between Jsc and Voc, which can productively promote the development of the OSC field.
Switchable Chemo‐, Regio‐ and Pseudo‐Stereodivergence in Palladium‐Catalyzed Cycloaddition of Allenes

Published: July 2024

AbstractHere, we report a strategy enabling triple switchable chemo‐, regio‐, and stereodivergence in newly developed palladium‐catalyzed cycloadditions of allenes. An asymmetric pseudo‐stereodivergent cycloaddition of allenes bearing a primary leaving group at the α‐position, where a dynamic kinetic asymmetric hydroalkoxylation of racemic unactivated allenes was the enantio‐determining step, is realized, providing four stereoisomers [(Z,R), (Z,S), (E,S), and (E,R)] containing a di‐substituted alkene scaffold and a stereogenic center. By tuning reaction conditions, a mechanistically distinctive cycloaddition is uncovered selectively with the same set of substrates. By switching the position of the leaving group of allenes, a cycloaddition involving an intermolecular O‐attack is disclosed. Diverse mechanisms of the cycloaddition reactions of allenes enable rapid access to structurally and stereochemically diverse 3,4‐dihydro‐2H‐1,4‐benzoxazines in high efficiency and selectivity.

AbstractThis study aimed to investigate the impact of porphyrin complexes with Cr3+ on the oxidative stability of biodiesel. Specifically, it focused on assessing the induction period as well as the fluorescence and FTIR spectroscopy, kinetic and thermodynamic parameters of oxidation under varying temperature conditions. The concentration of the metal added in the biodiesel samples, with and without protoporphyrin IX (PPIX), was established based on previous literature. Oxidative stability tests were carried out at 105, 110, 115, and 120°C. The Cr3+ transition metal ion exhibited low catalytic activity in biodiesel oxidation reactions, and the tests without PPIX showed lower induction period values for all temperatures. PPIX exhibited antioxidant action, delaying both the initiation and propagation stages of chain reactions responsible for the formation of free radicals, thereby enhancing the stability of the biofuel even in the presence of Cr3+, when compared to the same test without the addition of the compound. The fluorescence intensity of PPIX decreased as a function of the contact time with the metal ion, and the FTIR analysis of the biodiesel with PPIX presented the most significant variations in the spectra. The tests containing PPIX at all temperatures presented lower values of reaction rate than the control samples, while the test without PPIX with Cr3+ ion resulted in higher k in comparison to control. The activation energy values ranged from 43.36 to 106.37 kJ mol−1. The results of thermodynamic parameters indicated greater stability for biodiesel containing PPIX, with enthalpy activation (ΔH‡) and entropy activation (ΔS‡) values of 103.16 kJ mol−1 and ‐52.61 J.K−1.mol−1, respectively.

AbstractThe ability to fabricate resisting nonspecific protein adsorption electrochemical sensor capable of high biocompatibility in vivo will undoubtedly underpin key future developments in life sciences. Herein, a gelatin‐poly(lactide‐co‐glycolide)‐carbon nanotubes nanofibers‐membrane in three‐dimensional porous structure without any chemical crosslinking is constructed on the carbon fiber microelectrode (e‐Gelatin‐PLGA‐CNTs/CFME) using a one‐step electrospinning technology. The nanofibers‐membrane still presents good three‐dimensional porous structure and excellent hydrophily after implantation in BSA solution. In addition, the dopamine hydrochloride (DA) sensitivity at e‐Gelatin‐PLGA‐CNTs/CFME after implantation in human blood samples exhibits almost the same as preimplantation (91% ± 9%, n = 3). Importantly, the nanofibers‐membrane possesses fast cell proliferation and a low hemolysis rate (2.27% ± 0.76%), satisfying the required biocompatibility as a constructed material for the detection in vivo. The constructed micro‐electrochemical sensor realizes the detection of DA in human blood samples. Consequently, this strategy offers a new and facile platform for the development of implanted electrochemical sensor.
Dynamic event‐triggered‐based decentralized fault‐tolerant control for interconnected nonlinear time‐delay systems with unknown control directions
Authors: Shen Qixia , Lin Wenshuai , Cao Liang , Zhao Meng 
Published: July 2024

AbstractThe dynamic event‐triggered decentralized adaptive fault‐tolerant control strategy is designed for nonlinear interconnected systems with time delay and unknown control directions. The dynamic event‐triggered control scheme where the threshold parameters related to measurement errors are dynamically adjusted by introducing adaptive laws into the control law appropriately increases the time interval for controller update. Then, the Nussbaum function and linear transformation are employed to handle the coupling problem caused by actuator faults and unknown control directions. Meanwhile, the Lyapunov–Krasovskii function is utilized to compensate the effect of time delay and guarantees that all closed‐loop signals are bounded. The errors converge into bounded compact sets around the origin. The validity of the presented scheme is verified via a simulation example.
