L'apprentissage/enseignement de la morphologie écrite du nombre en français

La morphologie joue un role essentiel en Francais a l'ecrit. En effet, de nombreuses marques morphologiques n'ont pas de correspondant oral. Ceci est le cas des flexions du nombre : -s pour le pluriel des noms et adjectifs et -nt pour les verbes a la troisieme personne du present de l'indicatif. Des recherches anterieures (Totereau, Thevenin et Fayol, 1997 ; Totereau, Fayol et Barrouillet, 1998) ont montre que d'une part, l'interpretation de ces marques precede leur production, que le traitement de la flexion nominale (-s) est plus precoce et mieux assure que celui de la flexion adjectivale (-s), et que l'apparition de la flexion verbale (-nt) est encore plus tardive. D'autre part, ces etudes ont permis d'observer des erreurs de surgeneralisations : utilisation erronee des flexions d'abord nominale aux verbes (ils timbres) et, plus tard et plus rarement, de la flexion verbale aux noms et adjectifs (les timbrent rougent). Toutes ces recherches presentent une insuffisance majeure : les conditions de l'apprentissage n'y ont pas ete controlees. L'experience rapportee ici vise precisement a tester que l'acquisition de la morphologie du nombre a l'ecrit par des enfants de la premiere a la troisieme annees primaires s'effectue de maniere plus precoce et rapide lorsque d'une part, les regles d'accord donnent lieu a une instruction directe plutot qu'a une « simple » impregnation par l'ecrit (Groupe Controle) ; et d'autre part, que l'apprentissage est plus efficace lorsqu'il comporte des evaluations et corrections explicites (Groupe avec feed-back) en plus de l'enseignement direct des regles et de la pratique d'exercices (Groupe sans feed-back). Les resultats montrent que l'introduction d'une instruction directe assortie d'exercices (Groupe sans feed-back et groupe avec feed-back) entraine tres precocement des modifications profondes des performances : le non-marquage disparait des la premiere annee primaire, la frequence des accords exacts augmente pour toutes les categories grammaticales.
Tending Wounds

The authors extend the metaphor of wound healing in medicine to organizations and propose a model of organizational healing. Organizational healing differs from resilience, hardiness, and recovery and refers to the actual work of repairing and mending the collective social fabric of an organization after crisis. Using a qualitative research study based on interview data gathered after a shooting incident in a Midwestern university, the authors propose a model of organizational healing that includes three stages of healing and six key enablers: inflammation—prioritizing individual in need of urgent care and minimizing the potential for recriminations; proliferation—fostering high-quality connections and improvising on routines; and remodeling—strengthening a family organizational culture and initiating ceremonies and rituals. The authors offer implications for how organizations manage these enablers after crisis and suggest that organizations adopting these are more likely to experience healing.
Resource Allocation and Scheduling in Multi-Cell OFDMA Decode-and-Forward Relaying Networks

In this paper, we formulate a joint optimization problem for resource allocation and scheduling in multi-cell orthogonal frequency division multiple access (OFDMA) half-duplex decode-and-forward (DF) relay assisted networks. Our problem formulation takes into account multi-cell interference and heterogeneous data rate requirements. We transform the resulting non-convex and combinatorial optimization problem into a standard convex optimization problem by introducing an additional interference constraint, which constitutes a performance lower bound for the original problem. Subsequently, the transformed optimization problem is solved by using dual decomposition and a centralized iterative resource allocation algorithm with closed-form power and subcarrier allocation policies is derived maximizing the average weighted system throughput (bit/s/Hz/base station). Simulation results illustrate that our proposed algorithm approaches the maximum achievable throughput and provides substantial performance gains compared to single-cell optimization.
U-Curve Association between Timing of Renal Replacement Therapy Initiation and In-Hospital Mortality in Postoperative Acute Kidney Injury

Background Postoperative acute kidney injury (AKI) is associated with poor outcomes in surgical patients. This study aims to evaluate whether the timing of renal replacement therapy (RRT) initiation affects the in-hospital mortality of patients with postoperative AKI. Methodology This multicenter retrospective observational study, which was conducted in the intensive care units (ICUs) in a tertiary hospital (National Taiwan University Hospital) and its branch hospitals in Taiwan between January, 2002, and April, 2009, included adult patients with postoperative AKI who underwent RRT for predefined indications. The demographic data, comorbid diseases, types of surgery and RRT, and the indications for RRT were documented. Patients were categorized according to the period of time between the ICU admission and RRT initiation as the early (EG, ≦1 day), intermediate (IG, 2–3 days), and late (LG, ≧4 days) groups. The in-hospital mortality rate censored at 180 day was defined as the endpoint. Results Six hundred forty-eight patients (418 men, mean age 63.0±15.9 years) were enrolled, and 379 patients (58.5%) died during the hospitalization. Both the estimated probability of death and the in-hospital mortality rates of the three groups represented U-curves. According to the Cox proportional hazard method, LG (hazard ratio, 1.527; 95% confidence interval, 1.152–2.024; P = 0.003, compared with IG group), age (1.014; 1.006–1.021), diabetes (1.279; 1.022–1.601; P = 0.031), cirrhosis (2.147; 1.421–3.242), extracorporeal membrane oxygenation support (1.811; 1.391–2.359), initial neurological dysfunction (1.448; 1.107–1.894; P = 0.007), pre-RRT mean arterial pressure (0.988; 0.981–0.995), inotropic equivalent (1.006; 1.001–1.012; P = 0.013), APACHE II scores (1.055; 1.037–1.073), and sepsis (1.939; 1.536–2.449) were independent predictors of the in-hospital mortality (All P<0.001 except otherwise stated). Conclusions The current study found a U-curve association between the timing of the RRT initiation after the ICU admission and patients’ in-hospital mortalities, and alerts physicians of certain factors affecting the outcome after the RRT initiation.
Cardboard Mobile Virtual Reality as an Approach for Pain Distraction in Clinical Settings: Comparison, Exploration and Evaluation with Oculus Rift

Immersive Virtual Reality (VR) has been shown to work as a non-pharmacological analgesic by distracting patients from their acute pain for short periods of time. However, few researchers have investigated the effectiveness of mobile "Cardboard VR" for chronic pain patients. In this research, the viability of the Cardboard VR was examined by comparing it to another Head-Mounted Display (HMD), the Oculus Rift (OR), a desktop HMD. A randomized crossover study was conducted in a pain clinic with 30 chronic pain patients. OR was found to be significantly more effective than both the Cardboard VR and the control condition. Nevertheless, the results of this study demonstrate that Mobile VR has potential to become an effective tool for managing chronic pain because it is comparatively more affordable than VR that is restricted to desktop computers, because it can be deployed in numerous contexts, and because of its ease of use.

Bioavailability of the amino acid-attached prodrug as a new anti-HIV agent in rats

The primary objective of this study was to compare the pharmacokinetics of a new anti-human immunodeficiency virus agent 1-(2-amino-pyridin-4-ylmethyl)-6-(3,5-dimethyl-benzoyl)-5-isopropyl-1H-pyrimidine-2,4-dione (VP-0502) with its amino acid prodrug alanine amide of VP-0502 (VP-0502AL), following intravenous and oral administrations to rats. The plasma concentrations of both analytes were analyzed via high-performance liquid chromatography coupled with photodiode-array detection (HPLC-DAD). When VP-0502 was intravenously administered at 20 mg/kg, the analyte appeared in low levels with an AUC of 0.3 µg · h/ml, and C0 of 0.2 µg/ml in plasma. However, both the prodrug VP-0502AL and its metabolite VP-0502 appeared at comparatively higher levels following intravenous injection of VP-0502AL at the same dose. VP-0502AL's pharmacokinetic parameters were Vd: 4.6 l/kg; AUC: 3 µg · h/ml; t1/2: 0.5 h; C0: 6 µg/ml; CLtot: 7 l/h/kg; and MRT: 0.6 h. Following oral administration of VP-0502 (100 mg/kg), it was not detectable in plasma (<50 ng/ml), while after the oral administration of VP-0502AL, VP-0502 was quantitatively detected as an active metabolite for the first 7 h, with a maximum plasma concentration (Cmax) of 0.8 µg/ml, and an area under the concentration-time curve (AUC) of 2 µg · h/ml. The oral pharmaco-kinetic parameters of VP-0502AL were calculated to be: maximum concentration time (tmax) 2.7 h; Cmax 0.2 µg/ml; elimination half-life (t1/2): 0.8 h; and AUC 0.5 µg · h/ml. Overall the findings indicate that VP-0502AL has a favorable pharmacokinetic profile as a prodrug with rapid transformation into the active metabolite, and that the attachment of the amino acid alanine to VP-0502 is an effective approach to improve its oral bioavailability. VP-0502AL is predicted to become a new highly bioavailable anti-AIDS drug candidate and/or lead compound.
Using fractional GM(1,1) model to predict maintenance cost of weapon system

In order to improve the prediction performance for maintenance cost of weapon system, grey system model with the fractional order accumulation (FGM(1,1)) is used to predict the maintenance cost of weapon system with small sample. FGM(1,1) yielded the lower MAPE in the in-sample model and the much lower MAPE in the out-of-sample model, which means that FGM(1,1) can predict the memory process. FGM(1,1) can predict the maintenance cost of other weapon system.
Posterior parietal cortex and long-term memory: some data from laboratory animals

The posterior parietal cortex (PPC) was long viewed as just involved in the perception of spatial relationships between the body and its surroundings and of movements related to them. In recent years the PPC has been shown to participate in many other cognitive processes, among which working memory and the consolidation and retrieval of episodic memory. The neurotransmitter and other molecular processes involved have been determined to a degree in rodents. More research will no doubt determine the extent to which these findings can be extrapolated to primates, including humans. In these there appears to be a paradox: imaging studies strongly suggest an important participation of the PPC in episodic memory, whereas lesion studies are much less suggestive, let alone conclusive. The data on the participation of the PPC in episodic memory so far do not permit any conclusion as to what aspect of consolidation and retrieval it handles in addition to those dealt with by the hippocampus and basolateral amygdala, if any.
Everyday expectations of the state during Pakistan's early years: Letters to the Editor, Dawn (Karachi), 1950–1953

Abstract Accessing the day-to-day, albeit pressing, concerns of Pakistanis in the early 1950s can be difficult as a result of the relative paucity of relevant primary material. One set of sources, however, are the letters written to the editors of contemporary newspapers during this period, in which correspondents outlined their expectations of, made demands on, and aired their frustrations with, the everyday state in the years following independence and Pakistan's creation. This paper draws on a sample of this correspondence on the letter pages of Dawn (Karachi) during 1950–1953 in order to explore the views of ordinary citizens as they grappled with problems of housing, transport, food rationing, water shortage, and corruption.
Spatiotemporal structure of complex cell receptive fields and influence of GABAergic inhibition

Spatiotemporal receptive field (RF) profiles were mapped with reverse correlation technique for complex cells in the striate cortex of cat. The RFs were constituted with ON and OFF subfields that overlapped much extensively in space and also largely in time. The subfields had spatial width of 1.0–4.3° and temporal duration of 33–139 ms, whereas late responses were absent in most cases. When microiontophoresis of &ggr;-aminobutyric acid type A (GABAA) antagonist bicuculline was performed on the cells, little change occurred in width and onset time of the subfields, but the duration was prolonged in a subset of cells. These results suggest that intracortical inhibition may contribute to improve the accuracy of visual signals encoded in neuronal activities, but is unlikely critical for determining the primary structure of complex cell RF.
Regulative Wavelength Grouping Approach for QoS in OBS Networks

In this study, a wavelength grouping approach has been proposed for core nodes in OBS in order to control byte drop rates for different classes of traffic. Preemptive Channel Scheduling Algorithm (PCSA) has been used for channel scheduling in OBS. In terms of performance criteria, loss rate in bytes is considered. A 2-state MMPP (Markov Modulated Poisson Process) traffic generator on a 14-node mesh network topology illustrating NSFNET is designed as the testbed. NS2 Network Simulation tool is used for our tests. In OBS algorithms, bursts are created using a hybrid model that takes into account both timeout and maximum length threshold mechanisms. In nodes, in order to satisfy QoS requirements, priority based queuing and Regulative Wavelength Grouping (RWG) are used. In priority based queuing, packets (bursts) are sent according to their priority order. RWG mechanism, where the number of wavelengths for each traffic class is arranged for adjusting the packet drop probability of different classes of client traffic under a specific threshold value, is used for providing priority levels. According to the simulation studies, RWG algorithm gives better results in OBS for high priority traffic performance.
Teaching calcium-induced calcium release in cardiomyocytes using a classic paper by Fabiato.

This teaching paper utilizes the materials presented by Dr. Fabiato in his review article entitled "Calcium-induced release of calcium from the cardiac sarcoplasmic reticulum. " In the review, supporting evidence of calcium-induced calcium release (CICR) is presented. Data concerning potential objections to the CICR theory are discussed as well. In closing, technical issues associated with the skinned cell model are mentioned. Based on this review article, teaching and learning points are put forth in this article to highlight two concepts: 1) the regulatory mechanisms of CICR in cardiomyocytes and 2) the recognition of contradicting hypotheses and limitations in experimental design. The first concept is certainly an important one for physiology students. The second concept is universally applicable to researchers in all fields of science. It is thus the aim of this article to cultivate a rewarding teaching and learning experience for both instructors and students.
Symptom-Based Disease Prediction Using Machine Learning

Accurate prediction of disease is a major challenge in the current healthcare sector, where on-time and correct diagnosis can remarkably impact treatment outcomes. This research introduces a user-focused approach to predicting diseases, using machine learning along with a mobile application interface. Empowering individuals with the ability to assess their health and make well-informed decisions is the primary aim of this research. Our machine-learning model demonstrates exceptional accuracy, often achieving a 100% accuracy rate. This includes the incorporation of various algorithms such as Multinomial Naive Bayes, Decision Tree, and Random Forest. The cross-validation score serves to validate the robustness of the model. Furthermore, the high F1 score of 0.99 under-scores its effectiveness in providing accurate predictions for different classes of diseases. The integration of a user-friendly Flutter mobile application streamlines the procedure of entering symptoms and obtaining disease predictions, enhancing the user experience. In addition to disease prediction, our system enhances its utility by providing supplementary materials from external platforms such as YouTube video suggestions, doctor's blogs, and podcasts through third-party APIs, delivering a holistic understanding of predicted diseases. This research makes notable advancements in bridging the gap between individuals and crucial health information. Our system exhibits potential as a tool for early disease detection, improving health awareness, and contributing to public health and well-being.
Clearing the way for physicians' use of clinical information systems

F or almost three decades computer-based information systems have been developed and implemented in health care settings. Under cost-based reimbursement, hospital information systems were designed primarily for administrative purposes to ensure that all charges were billed and collected. Physicians on the whole wrote orders in their traditional manner while ward clerks entered these written orders into the information system. The 1990s have witnessed a shift from administrative systems to clinical information systems used by providers in delivering patient care. Health care institutions are information-intensive. Demands for information have intensified due to changes in reimbursement for Medicare patients; the increase in prepaid contracts; and a focus on cost-effectiveness, quality assurance, and clinical outcomes. The current goals of cost containment and outcomes measurement can not be met by the older administrative systems. These older systems ignored the fact that as much as 75% of health care costs are determined by the provider. Moreover, most of these information systems were incapable of providing data on patient outcomes and instead relied on manual chart reviews. In recognition of the critical importance that medical records play in the delivery of health care, the Institute of Medicine (IOM) called for the development and implementation of computer-based patient records (CPRs). The IOM broadly defined a CPR as “. an electronic patient record that resides in a system specifically designed to support users through availability of complete and accurate data, practitioner reminders and alerts, clinical decision support systems, links to bodies of medical knowledge, and
Teachers’ Work: some complex interactions between teachers and their schools

Abstract Teachers’ work is broadly conceptualised in two ways in the educational literature. First, there is the view that it is determined by structural constraints which shape and limit teachers’ practice. Secondly, it is understood as taking place in a situation in which teachers have considerable personal autonomy to direct and develop their own practice. Drawing on a study using a qualitative methodology, a middle‐ground position is explored. Teachers from two different school environments are studied and comparisons are drawn which illuminate some similarities and differences in their work situations. These in‐depth descriptions highlight the complexities of teachers’ work. Moreover, they demonstrate that both situational contexts and aspects of individual teachers’ personal characteristics interact to influence what happens at school. Adequate understanding of teachers’ work must capture this dual influence, especially when implications are drawn about changing teachers’ work.
Scaling Laws for Ergodic Spectral Efficiency in MIMO Ad-Hoc Networks

This paper considers a multi-antenna wireless net- work where the locations of transmitters are distributed as a Poisson point process, which is a natural model for ad-hoc and device-to-device networks. We show that, in such a network, the ergodic spectral efficiency scales linearly with respect to the network density under appropriate multiple antenna configurations and diversity assumptions. This scaling law is achieved by a simple zero-forcing decoder, which eliminates inter-stream interference using spatial multiplexing transmissions. We also show that when each receiver knows channel state information from some interferers, a higher scaling law holds for ergodic spectral efficiency than that without channel state information when using a partial zero-forcing method which eliminates dominant interference signals while boosting the desired signal power. Further, we show that spatial multiplexing transmission methods are essential for obtaining better scaling laws in certain regions of network parameters.
Minnesota preschool inventory identification of children at risk for kindergarten failure

The Minnesota Preschool Inventory provides a systematic, standardized method for screening prekindergarten children based upon the mother's report of the child's current development, adjustment, and symptoms. The inventory format and the Minnesota Preschool Inventory Profile norms provide a convenient means for obtaining developmental information and for identifying those children who are at risk for kindergarten failure. Normative data are based upon a sample of 360 Bloomington, Minnesota prekindergarten children. Validity data are presented in terms of correlation and congruence between the mothers' Minnesota Preschool Inventory descriptions of the children obtained at kindergarten roundup and teachers' ratings of overall kindergarten performance obtained at the end of the school year. Among the developmental scales of the Inventory, Comprehension, Memory, Letter Recognition, and Number Comprehension were related to kindergarten performance; the Self-Help, Fine Motor, and Expressive Language scales were not. The adjustment scales were not significantly related to kindergarten performance. The Comprehension, Memory, Letter Recognition, and Number Comprehension scales together identified 12 of the 20 students who were rated in the bottom 5% of students by their teachers, while misidentifying only 3% of successful students as at risk. The symptoms items of the Inventory identified an additional three of the eight poorly performing students who were not identified by the developmental scales.
