Depuis plusieurs années déjà, un mouvement de fond existe au sein de notre Université qui tend à accompagner les savoirs au-delà des murs académiques. Tout récemment d’ailleurs, avec la création d’un vice-rectorat à la citoyenneté, cette tendance s’est approfondie, formalisée. Dans les équipes qui mettent en œuvre cette volonté institutionnelle d’extériorisation et de mise en débat, on compte bien plus de femmes que d’hommes. Une hypothèse, pour expliquer ce fait, peut être formulée concernant la place de femmes à ces postes. L’adéquation de certaines qualités, et aussi d’une certaine éthique, dite féminine, à la politique de diffusion des savoirs pourrait être une question à creuser. A partir de d'un ensemble de théories - rassemblées sous l'appellation de care - nous interrogeons l'analogie entre pensée féminine et pensée citoyenne. [less ▲]

INTRODUCTION: The treatment of patellar tendinopathies could be difficult. This is the reason why new treatments have been developed, among which platelet rich plasma (PRP) injections. Some clinical series have previously evaluated the effect of PRP in the treatment of proximal patellar tendinopathies. Recent systematic review concluded that PRP could be recommend as a treatment in such indication (1). Recently, the viscoelastic properties of hyaluronic acid (HA) on liquid connective tissue have been proposed for the treatment of tendinopathies (2). Some fundamental studies show encouraging results on HA’s ability to promote tendon gliding and reduce adhesion as well as to improve tendon architectural organisation. Some observations also support its use in a clinical setting to improve pain and function. PURPOSE: We aimed to compare the effect of PRP injection versus two injections of HA after three months on patients who have a proximal patellar tendinopathy. METHODS: Thirtythree sportsmen with proximal patellar tendinopathies being not relieved after minimum three months of normal physiotherapy treatments where included. Eighteen of them (group 1) have received a leukocyte poor PRP injection (obtained using an aphaeresis machine (3)) and the other fifteen (group 2) two HA injections, all of them have benefited of standardized rehabilitation. Concerning the evaluation of the pathology, algofunctional tests (visual analogic scale (VAS), pressure algometer, IKDC score, VISAP score), isokinetic (associated to VAS) along with the patellar tendon ultrasonography (US) have been realized over three times (preinjection, after 6 weeks, after 3 months postinjections). RESULTS: The results of VAS (p<0,01), algometric scores (p<0,01), IKDC scores (p<0,01) and VISAP (p<0,01) show a considerable improvement in the two groups, but not for the US findings. For the group 1, isokinetic tests show significative results for the hamstrings in C60°/s with an improvement of maximum peak torque (p=0,01) for the pathological member, a diminution (p>0,05) for the healthy limb and during the analysis of the bilateral difference (p=0,0002). For the group 2, the improvement of quadriceps maximum peak torque in C240°/s is significant (p>0,01) for the pathological knee after 6 weeks post injections only. The VAS associated with isokinetic tests decreases significantly for all contraction modes after three months of study. CONCLUSIONS: Both PRP and HA can improve the symptoms of proximal patellar tendinopathy, even if the results are slightly better in the PRP group.

Colectivo e interdiciplinario, este volumen conmemorativo de los 150 años de la muerte de Baudelaire reúne en sus páginas las contribuciones de diez especialistas en tres partes equilibradas que reflejan el itinerario baudeleriano y la recepción de su obra en Hispanoamérica (Alain Vaillant, Juan Zapata, Jean-Pierre Bertrand, Pascal Durand, Robert Kopp, Steve Murphy, Antoine Compagnon, David Marín Hernández, Glyn Hambrook, Santiago Venturini). Existe en los textos aquí compilados una preocupación latente por articular los aportes más recientes de la poética, la sociología de la literatura y la historia literaria para la comprensión y elucidación de una obra tan paradójica y controversial como su autor. Surge así una nueva lectura de Baudelaire y de su legado literario particularmente importante en nuestro medio académico, atrapado desde hace ya algunos años, sobre todo en el caso que nos ocupa, en visiones esencialistas y de tipo puramente monográfico que tienden a ocultar las dinámicas colectivas e institucionales que gobiernan las prácticas culturales.

Background Migraine is a complex multifactorial disease that arises from the interaction between a genetic predisposition and an enabling environment. Habituation is considered as a fundamental adaptive behaviour of the nervous system that is often impaired in migraine populations. Given that migraineurs are hypersensitive to light, and that light deprivation is able to induce functional changes in the visual cortex recognizable through visual evoked potentials habituation testing, we hypothesized that regional sunlight irradiance levels could influence the results of visual evoked potentials habituation studies performed in different locations worldwide. Methods We searched the literature for visual evoked potentials habituation studies comparing healthy volunteers and episodic migraine patients and correlated their results with levels of local solar radiation. Results After reviewing the literature, 26 studies involving 1291 participants matched our inclusion criteria. Deficient visual evoked potentials habituation in episodic migraine patients was reported in 19 studies. Mean yearly sunlight irradiance was significantly higher in locations of studies reporting deficient habituation. Correlation analyses suggested that visual evoked potentials habituation decreases with increasing sunlight irradiance in migraine without aura patients. Conclusion Results from this hypothesis generating analysis suggest that variations in sunlight irradiance may induce adaptive modifications in visual processing systems that could be reflected in visual evoked potentials habituation, and thus partially account for the difference in results between studies performed in geographically distant centers. Other causal factors such as genetic differences could also play a role, and therefore well-designed prospective trials are warranted. [less ▲]

Compliant mechanisms are flexible components which can store elastic energy when deformed and then passively release it to produce a motion. Their scope of applications encompasses various domains from robotic orthoses to microscopes and grippers. In this work, the developments focus on compliant mechanisms called tape springs used in deployable space structures. Tape springs, due to their autonomous deployment capacity from a compact folded configuration, their high stiffness in the deployed equilibrium state and their simplicity of integration, represent efficient alternatives to common motorised hinges for space applications. Thus, they are currently used to deploy appendices on satellites such as solar panels or telescopes and are considered as valuable components in the design of future applications such as solar sails, deployable optics and inflatable structures. However, their structural behaviour is highly nonlinear and quite sensitive to the design parameters and to the various constraints encountered on Earth and in a space environment. The objective of this thesis is thus to develop validated high-fidelity dynamic models of tape springs which can be used to support the design process. The methodology involves the development of advanced finite element models and experimental tests based on an original set-up. First, a quasi-static model based on shell finite elements is established and used to investigate the nonlinear response of tape springs as well as the influence of various geometric parameters. This model is then exploited for the design of tape springs deploying a reflector based on an automatic optimisation procedure. The study is further extended to dynamic analyses, which are characterised by a self-locking of the tape springs in their final deployed configuration. In order to accurately capture these phenomena, the importance of a suitable representation of the physical structural dissipation in the model is demonstrated and, for metallic tape springs, a Kelvin-Voigt model is retained. An experimental set-up is then designed in order to validate the model and its capacity to represent the nonlinear phenomena inherent to tape springs which occur during quasi-static and dynamic tests. The experimental data are acquired by the means of an innovative 3D motion analysis system and a force plate. The reproducibility of the tests is assessed and a procedure, involving several elementary tests, is proposed to identify the parameters of the finite element model, in particular, the structural damping. In the end, a fair correlation between the experimental and numerical results is achieved. The proposed methodology, which relies on numerical and experimental methods, thus leads to a dynamic model of tape springs which can be used to predict their behaviour in various conditions.

Although the linguistic content of hypnotic suggestions has been investigated in various studies, the paralinguistic aspects – that is, the voice used by hypnotherapists – are little described. The few indications concerning vocal patterns that promote a state of hypnotic trance are limited to subjective descriptions based on clinical observations, as reported in textbooks (Grinder & Bandler, 1997; James, 2010). From an empirical point of view, voice characteristics have been assessed objectively with acoustic measures in the context of muscle relaxation (Knowlton & Larkin, 2006); however, to the best of our knowledge, such measures have not been applied to identify vocal indices of the voice used to induce hypnosis. The aim of this study is to investigate the existence of a voice pattern specific to hypnosis. To that end, 32 French-speaking therapists (18 women and 14 men) who practice hypnosis in a medical or psychological context were recorded while reading a single text in two conditions: with a normal voice and with a voice used for hypnotic induction. For each of these two conditions, the following acoustic analyses were conducted with Praat software: degree of voicing (in %), mean fundamental frequency (F0, in Hz), mean sound pressure level (SPL, in dB), and variability of F0 and SPL. Statistical analyses (Wilcoxon test) show that, compared to a normal voice, a hypnotic voice presents less voicing (p<.001), lower F0 and SPL (p<.001), less SPL variability (p=.003), and a trend toward less F0 variability (p=.056). These preliminary results allow us to provide objective acoustic correlates of a hypnotic voice, such as low frequency, low intensity, monotone and lack of voicing. These acoustic characteristics correspond to the subjective voice descriptions given in textbooks, such as quiet, gentle, reassuring, and warm, which tend to create a sense of intimacy and confidentiality. Regarding the lower degree of voicing in hypnotic voices, subsequent analyses will make it possible to test the hypothesis that the voice is breathy and whispery, at least at times, and that there are longer pauses than in a normal voice. Analyses of spontaneous speech during hypnosis sessions are currently under way to test the generalizability of the results presented here. References -Grinder, J., & Bandler, R. (1997).
