Pratiques agricoles innovantes et logistique des coopératives agricoles. Une étude ex-ante sur l’acceptabilité de cultures associées blé dur-légumineuses

La diffusion de pratiques agricoles innovantes pose la question de leur acceptabilite au sein des filieres. Cet article vise a evaluer ex ante les caracteristiques logistiques des cooperatives agricoles susceptibles de favoriser l’adoption de ces pratiques et en particulier les cultures associees ble dur-legumineuses. Il s’appuie sur une enquete de l’organisation logistique des cooperatives agricoles, collectant et stockant du ble dur en Midi-Pyrenees. L’hypothese posee est que les acteurs des filieres peuvent etre plus ou moins receptifs a ces nouvelles pratiques selon les marges de manœuvre dont ils disposent pour faire evoluer leurs systemes. Il ressort de cette etude que les cooperatives indiquant que leur logistique serait a priori compatible avec ces nouvelles pratiques, sont aussi celles orientees vers une gestion par la qualite. Ces cooperatives dotees de moyens specifiques et d’un ensemble de competences favorisant l’adaptation a une plus grande diversite de cultures presentent des capacites de resilience plus importantes.
Multisensory aspects of the spatial cuing of driver attention

﻿ The primary goal of the empirical research outlined in this thesis was to examine a number of the factors contributing to the design of more ergonomic multisensory warning signals, that is, signals that elicit efficient and effective responses from interface operators under demanding conditions. To achieve this goal, a series of experiments was conducted in order to examine the nature and consequences of the crossmodal links inherent in spatial attention between various different sensory modalities, such as audition, vision, and touch, in an applied setting. In particular, a laboratory-based simulated driving task was used to investigate the effectiveness of various different auditory and vibrotactile cues in orienting a driver's attention to potential emergency driving events seen through the front windscreen or rearview mirror. The results of the first set of auditory spatial cuing experiments highlighted a significant performance advantage when the target driving events occurred in the cued, rather than the uncued, direction, with the biggest benefits being seen following spatially-predictive auditory or verbal cues. The second set of vibrotactile spatial cuing experiments demonstrated the potential utility of vibrotactile warning signals for presenting spatial information to car drivers, and the results were successfully replicated in a study using a high-fidelity driving simulator. The third set of experiments, incorporating an orthogonal task design, were conducted in order to examine the mechanisms responsible for the advantageous spatial cuing effects reported in the earlier experiments. Taken together, the results demonstrated that while directional congruency between a warning signal and target driving event may be sufficient to facilitate performance due to the priming of the appropriate response, attentional facilitation (i.e., perceptual enhancement) typically requires the co-location of the cue and target within the same functional region of space. In sum, this thesis demonstrates the potential value of approaching the design of effective multisensory warning signals for human operators by studying the information processing mechanisms in the human brain. The findings outlined here add to the literature concerning the brain's differential representation of stimuli presented in peripersonal as opposed to extrapersonal space. Further experimental chapters detail experiments that examined verbal directional cuing, olfactory cuing, and crossmodal interactions in virtual haptic environments.
Electromagnetic Design of 10 MW Class Fully Superconducting Wind Turbine Generators

We have studied a 10 MW class fully superconducting synchronous machine for direct-drive wind turbine generators. This machine has been designed using two kinds of superconducting wires. Multifilament wires have been used for armature windings. The DC field coils of the machine rotor are made of HTS tapes. Electromagnetic design of the generators has been carried out by FEM analysis. Analysis results show that 10 MW output is achievable with less use of HTS tapes than wind turbine generators having superconducting field coils and copper armature windings. Then, calculated AC losses are low.
Neuropsychological profiles of children and adolescents with craniosynostosis

Craniosynostosis refers to the premature fusion of one or more cranial sutures, and typically occurs in utero. The major craniofacial disorders that feature craniosynostosis are the syndromic craniosynostoses, in which raniosynostosis occurs within a broader symptom complex (e.g. cardiac, respiratory and hearing impairments), and the nonsyndromic craniosynostoses, in which craniosynostosis presents in isolation. Reconstructive surgery to remodel the cranium is required in most cases, normally between 6 to 12 months of age. The risks of adverse central nervous system and cognitive sequelae are well documented in these conditions. Whilst the syndromic craniosynostoses have historically been associated with varying degrees of intellectual impairment, the nonsyndromic forms have been regarded to have relatively benign cognitive sequelae. There is limited empirical literature addressing the long-term neuropsychological consequences of these disorders. Of that available, cognitive fuctions beyond global intelligence have seldom been examined, and no prior studies have comprehensively evaluated the wide array of cognitive skills that are important for adaptive functioning utilising standardised psychometric tools. This cross-sectional study sought to address these gaps in the developmental literature on the craniosynostoses and comprehensively describe the neuropsychological profiles of 34 children and adolescents with syndromic (n=13) and nonsyndromic (n=21) craniosynostosis. Children of between 7 and 16 years of age (mean age 11 years) completed a battery of neuropsychological tests, measuring intelligence, attention, memory and leaming, academic, executive and social and behavioural functioning.
Local Search Heuristics for Media Streams Planning with Transcoding

Recent advances in processing capabilities of commodity hardware enabled deployment of high-performance collaborative environments in various application fields, where maximum image quality and interactivity are critical. In this paper, we focus on user-empowered collaborative environments that rely on information available to the users and that can be obtained from the end-nodes connected to the network. We build upon our previous work on scheduling strategies for multi-point data distribution, while utilizing media transcoding during the distribution and partial network topology knowledge that may be provided by the users. The novelty introduced by this paper focuses on improving scheduling scalability by employing local search metaheuristics, allowing us to maintain systems comprising more than twice as many applications compared to the previous approaches.
Role of Ornibactin Biosynthesis in the Virulence ofBurkholderia cepacia: Characterization of pvdA, the Gene Encoding l-OrnithineN5-Oxygenase

ABSTRACT Burkholderia cepacia is a frequent cause of respiratory infections in cystic fibrosis patients. B. cepacia has been shown to produce at least four siderophores which may play a role in the virulence of this organism. To characterize genes involved in the synthesis of siderophores, Tn5-OT182 mutants were isolated in strain K56-2, which produces two siderophores, salicylic acid (SA) and ornibactins. Two mutants were characterized that did not produce zones on Chrome Azurol S agar in a commonly used assay to detect siderophore activity. These mutants were determined to produce sevenfold more SA than K56-2 yet did not produce detectable amounts of ornibactins. These mutants, designated I117 and T10, had a transposon insertion in genes with significant homology to pyoverdine biosynthesis genes of Pseudomonas aeruginosa. I117 contained an insertion in a pvdA homolog, the gene for the enzymel-ornithine N5-oxygenase, which catalyzes the hydroxylation of l-ornithine. Ornibactin synthesis in this mutant was partially restored when the precursorl-N5-OH-Orn was added to the culture medium. T10 contained an insertion in a pvdDhomolog, which is a peptide synthetase involved in pyoverdine synthesis. β-Galactosidase activity was iron regulated in both I117 and T10, suggesting that the transposon was inserted downstream of an iron-regulated promoter. Tn5-OT182 contains alacZ gene that is expressed when inserted downstream of an active promoter. Both I117 and T10 were deficient in uptake of iron complexed to either ornibactins or SA, suggesting that transposon insertions in ornibactin biosynthesis genes also affected other components of the iron transport mechanism. The B. cepacia pvdA homolog was approximately 47% identical and 59% similar tol-ornithine N5-oxygenase fromP. aeruginosa. Three clones were identified from a K56-2 cosmid library that partially restored ornibactin production, SA production, and SA uptake to parental levels but did not affect the rate of 59Fe-ornibactin uptake in I117. A chromosomalpvdA deletion mutant was constructed that had a phenotype similar to that of I117 except that it did not hyperproduce SA. ThepvdA mutants were less virulent than the parent strain in chronic and acute models of respiratory infection. A functionalpvdA gene appears to be required for effective colonization and persistence in B. cepacia lung infections.

Follow-up of N400 in the Rehabilitation of First-episode Schizophrenia

Background:The N400 component of event-related potentials (ERP) has recently drawn widespread attention at home and abroad. This study was to explore the relationship between N400 changes and risperidone treatment and rehabilitation in first-episode schizophrenia (FES). Methods:ERP component N400 was recorded by Guangzhou Runjie WJ-1 ERP instruments, in 58 FES before and 6 months, 15 months after risperidone treatment, and in 62 normal controls. The patients’ syndromes were assessed by Positive and Negative Syndrome Scale (PANSS). And the stimuli are Chinese sentences with matching (congruent) or mismatching (incongruent) ending words. Results:N400 latencies were prolonged, and amplitudes were decreased in Cz, Pz, Fz, C3, C4, in FES compared with in NC, before treatment. The prolonged N400 latencies and decreased amplitudes were negatively correlated with the patients’ positive scale and total scale of PANSS. There are significant differences of N400 amplitudes and latencies in 6 months and 15 months follow-up after treatment. Before treatment, 6 months and 15 months after treatment, N400 latencies are 446 ± 35 ms, 440 ± 37 ms, 414 ± 31 ms (F = 9.72, P < 0.01) in incongruent situation; N400 amplitudes are 5.2 ± 4.6 &mgr;V, 5.7 ± 4.8 &mgr;V, 7.3 ± 5.0 &mgr;V (F = 2.06, P > 0.05) in congruent situation, and 8.5 ± 5.9 &mgr;V, 10.1 ± 5.0 &mgr;V, 11.9 ± 7.0 &mgr;V (F = 3.697, P < 0.05) in incongruent situation. Conclusions:N400 could be used to predict the effects of treatment of schizophrenia to some degree. The linguistic and cognitive impairment in schizophrenia can be improved by antipsychotic drugs.
Effects of ergocalciferol added to calcium on the risk of falls in elderly high-risk women.

BACKGROUND Ergocalciferol (vitamin D(2)) supplementation plays a role in fall prevention, but the effect in patients living in the community in sunny climates remains uncertain. We evaluated the effect of ergocalciferol and calcium citrate supplementation compared with calcium alone on the risk of falls in older women at high risk of falling. METHODS A 1-year population-based, double-blind, randomized controlled trial of 302 community-dwelling ambulant older women aged 70 to 90 years living in Perth, Australia (latitude, 32 degrees S), with a serum 25-hydroxyvitamin D concentration of less than 24.0 ng/mL and a history of falling in the previous year. Participants were randomized to receive ergocalciferol, 1000 IU/d, or identical placebo (hereinafter, ergocalciferol and control groups, respectively). Both groups received calcium citrate, 1000 mg/d. Fall data were collected every 6 weeks. RESULTS Ergocalciferol therapy reduced the risk of having at least 1 fall over 1 year after adjustment for baseline height, which was significantly different between the 2 groups (ergocalciferol group, 53.0%; control group, 62.9%; odds ratio [OR], 0.61; 95% confidence interval [CI], 0.37-0.99). When those who fell were grouped by the season of first fall or the number of falls they had, ergocalciferol treatment reduced the risk of having the first fall in winter and spring (ergocalciferol group, 25.2%; control group, 35.8%; OR, 0.55; 95% CI, 0.32-0.96) but not in summer and autumn, and reduced the risk of having 1 fall (ergocalciferol group, 21.2%; control group, 33.8%; OR, 0.50; 95% CI, 0.28-0.88) but not multiple falls. CONCLUSION Patients with a history of falling and vitamin D insufficiency living in sunny climates benefit from ergocalciferol supplementation in addition to calcium, which is associated with a 19% reduction in the relative risk of falling, mostly in winter.
Self-Construal, Interpersonal Communication Satisfaction, and Communication Style: Engendering Differences

Abstract This study extends the literature on self-construal by examining its influence on male and female interpersonal communication satisfaction and communication styles in the U.S. The self-construal construct has been typically used to examine intercultural differences in self-definitions, but has not been used to study gender differences in the dominant culture of the U.S. The independent-samples t test revealed no significant difference between male and female independent and interdependent self-construals and direct communication style. However, there was a significant difference found between the two groups’ indirect communication style, with the male sample having a significantly higher mean. For the male sample, the regression analyses indicated that independent and interdependent self-construals are not predictive of their interpersonal communication satisfaction. For the female sample, the corresponding standardized and unstandardized regression coefficients indicated that their interdependent self-construal is more predictive of their interpersonal communication satisfaction than their independent self-construal.
Clustering analysis on alumni data using abandoned and Reborn Particle Swarm Optimization

Alumni data is one of the most important data that university management uses for developing the learning process decisions. This paper applies the idea of Abandoned and Reborn PSO (AR-PSO) to convert a clustering problem into the optimization form with an objective function to minimize the ugliness of the desired clusters. This algorithm of Clustering using AR-PSO (CAR-PSO) is slightly adapted to the cluster problem domain. The generated clusters need to be examined to decide if they are acceptable. There are three evaluations; the closeness, the separation and the purity. Finally, the experiment results show that the CAR-PSO is comparable with &-means in both types of alumni data while leaving the other two clustering algorithms.

A Novel STT-MRAM Cell With Disturbance-Free Read Operation

This paper presents a three-terminal Magnetic Tunnel Junction (MTJ) and its associated two transistor cell structure for use as a Spin Torque Transfer Magnetoresistive Random Access Memory (STT-MRAM) cell. The proposed cell is shown to have guaranteed read-disturbance immunity; during a read operation, the net torque acting on the storage cell always acts in a direction to refresh the data stored in the cell. A simulation study is then performed to compare the merits of the proposed device against a conventional 1-Transistor-1-MTJ (1T1MTJ) cell, as well as a differential 2-Transistor 2-MTJ (2T2MTJ) cell. We also investigate In-Plane Anisotropy (IPA) and Perpendicular-to-Plane Anisotropy (PPA) versions of the proposed device. Simulation results confirm that the proposed device offers disturbance-free read operation while still offering significant performance advantages over the conventional 1T1MTJ cell in terms of average access time. The proposed cell also shows superior performance to the 2T2MTJ cell, particularly when the cells are targeted for read-mostly applications.
ReCon: Revealing and Controlling PII Leaks in Mobile Network Traffic

It is well known that apps running on mobile devices extensively track and leak users' personally identifiable information (PII); however, these users have little visibility into PII leaked through the network traffic generated by their devices, and have poor control over how, when and where that traffic is sent and handled by third parties. In this paper, we present the design, implementation, and evaluation of ReCon: a cross-platform system that reveals PII leaks and gives users control over them without requiring any special privileges or custom OSes. ReCon leverages machine learning to reveal potential PII leaks by inspecting network traffic, and provides a visualization tool to empower users with the ability to control these leaks via blocking or substitution of PII. We evaluate ReCon's effectiveness with measurements from controlled experiments using leaks from the 100 most popular iOS, Android, and Windows Phone apps, and via an IRB-approved user study with 92 participants. We show that ReCon is accurate, efficient, and identifies a wider range of PII than previous approaches.
Silica-air double-clad optical fiber

A new design of the silica-air double-clad optical fiber is proposed. The fiber was prepared from an MCVD preform inserted into a supporting silica tube with a fluorine-doped connective element with a lower refractive index (/spl Delta/n/spl sim/-4/spl times/10/sup -3/) and air as the second cladding. A numerical aperture as high as 0.3 was measured for the first cladding and for fiber lengths up to 50 cm. Although it is realized that the results are preliminary, the optimization of the fiber parameters promises a new all-glass design for double-clad optical fibers for high-power fiber laser applications.
