La charge vocale se définit comme la quantité d'utilisation vocale en termes de durée et d'intensité vocale. Dans cette étude, nous tentons d'étudier la charge vocale selon ces deux aspects. Pour ce faire, nous avons proposé une tâche de lecture à 50 femmes non fumeuses, âgées de 22 à 47 ans, chez qui l'examen phoniatrique a exclu la présence de toute pathologie vocale. L'impact de la durée de l'utilisation vocale a été étudié à l'aide de récoltes de mesures toutes les 30 minutes, au cours d'une lecture de deux heures. Nous avons réalisé des mesures objectives (Fréquence fondamentale, Jitter %, Shimmer %, Noise-to-Harmonic Ratio, étendue fréquentielle, dynamique d'intensité, temps maximum de phonation) ainsi qu'une auto évaluation sur une échelle visuelle analogique (qualité vocale, sensation d'effort, de fatigue et d'inconfort laryngé au cours de la lecture). Afin de mettre en évidence l'effet de l'intensité, chaque participante a réalisé deux fois la tâche de deux heures de lecture, à minimum trois jours d'intervalle afin de permettre la récupération entre les deux conditions de test. Une première fois à intensité conversationnelle (entre 60 et 65 dB), une seconde fois à intensité élevée (entre 70 et 75 dB). L'objectif était d'étudier les modifications liées à la durée et à l'intensité de l'utilisation vocale ainsi que l'impact de l'échauffement et de la fatigue vocale sur les paramètres étudiés.

Objectives: To evaluate the impact on voice of 2 hours of continuous oral reading. Methods: Fifty normophonic women underwent two sessions of voice loading in which the required intensity level varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session. Ten expert judges evaluated the breathiness of one sentence recorded before and after each loading session. Pairs of stimuli were presented randomly to the judges, who were asked to designate the breathiest sample. Results: A significant decrease in breathiness was observed following both sessions, suggesting an improvement of voice subsequent to loading. When comparing the two intensity levels, no difference was found for breathiness after vocal loading. [less ▲]

From the Sahel to the coast, West Africa is experiencing a variety of climate change impacts, including sea level rise, soil salinization, floods, drought, and desertification, while simultaneously suffering from other forms of environmental degradation. Together, these environmental changes are significantly influencing migration patterns in and out of West Africa. This paper seeks to analyze vulnerability and resilience to environmental changes as they affect and are affected by mobility patterns in the region. We assert that the impact of environmental changes cannot be isolated from other political, social, economic, and demographic pressures that together drive human mobility. In a region where natural resources form the foundation of livelihoods and food security (fishing and agriculture), the relationship between environmental changes and socioeconomic vulnerabilities is of particular concern. This paper therefore draws from four distinct case studies to grasp the variegated and cumulative vulnerability and resilience among local populations as they relate to internal and intraregional migration.

Work environments have been encountering tremendous changes since the early 1990s. The enlargement of flexibility practices has raised concerns about well-being at work but also about safety. These two research areas, i.e. safety and well-being at work, have a strong tradition of diagnosis and research but there are few examples in the literature that attempt to link the two areas. Our goal in this study was to analyze the impact of both work variables and safety appraisal on well-being within a context of organizational changes. We used questionnaires on 4297 workers from a large company in the energy sector that has encountered big organizational changes these last years. Job control dimensions, safety appraisal, eustress and distress were measured using existing questionnaires. The results give some evidence for an additive explanation of eustress when adding safety appraisal in the hierarchical regression analysis. The additive effect of safety appraisal on distress was also significant but not enough strong to be considered seriously. A path analysis has shown that the effect of management safety climate on distress was rather an indirect effect through the job control dimensions. [less ▲]

We present an analytic model to estimate the capabilities of space missions dedicated to the search for biosignatures in the atmosphere of rocky planets located in the habitable zone of nearby stars. Relations between performance and mission parameters, such as mirror diameter, distance to targets, and radius of planets, are obtained. Two types of instruments are considered: coronagraphs observing in the visible, and nulling interferometers in the thermal infrared. Missions considered are: single-pupil coronagraphs with a 2.4 m primary mirror, and formation-flying interferometers with 4 × 0.75 m collecting mirrors. The numbers of accessible planets are calculated as a function of η[SUB]Earth[/SUB]. When Kepler gives its final estimation for η[SUB]Earth[/SUB], the model will permit a precise assessment of the potential of each instrument. Based on current estimations, η[SUB]Earth[/SUB] = 10% around FGK stars and 50% around M stars, the coronagraph could study in spectroscopy only ∼1.5 relevant planets, and the interferometer ∼14.0. These numbers are obtained under the major hypothesis that the exozodiacal light around the target stars is low enough for each instrument. In both cases, a prior detection of planets is assumed and a target list established. For the long-term future, building both types of spectroscopic instruments, and using them on the same targets, will be the optimal solution because they provide complementary information. But as a first affordable space mission, the interferometer looks the more promising in terms of biosignature harvest. [less ▲]

Oxidative stress has become of increasing interest in research and in equine and human medicine. If the pro-oxidant burden overwhelms the endogenous antioxidant defence of the organism, the arising imbalance between pro- and antioxidants is defined as oxidative stress. Different pathways might increase the generation of reactive oxygen species ( ROS) and results in oxidative stress. In physiological conditions, like during moderated exercise, the balance between ROS production and antioxidants allows to maintain an optimal organic function. In the light of the potentially deleterious role of excessive ROS production and the evidence that exercise-induced oxidative stress occurs in horses, the assessment of the antioxidant status should be considered in sport horses. Recent researches indicate that oxidative stress may play a role in physiopathology of several pathological syndromes in horses. Therefore, with classical treatment, the controlled administration of antioxidants appears interesting for the modulation of these processes, as well as in sport horses during intense exercise period.

The impact of cancer on the patient's family and caregivers is important and it can be analyzed in terms of coping strategies. It depends on the patient (age, sex, role ...), the illness (site, stage, state ...), the people (parents, siblings, caregivers ...), the time (diagnosis, treatment, death, after death rehabilitation), the prognosis. The survey of the literature underlines the methodological difficulties met in this complex field and the distress of the family and caregivers at each stage of the illness, even during long term remissions.

Coronary artery disease is the major cause of mortality of type 2 diabetic subjects. Its early diagnosis to prevent progression and clinical events has intuitive appeal. Somehow, rationale for screening has not been clearly established. Screening should not modify the medical therapy because diabetic subjects have to be treated in a secondary prevention strategy. We have no data from randomized trials concerning a better outcome after revascularization in this specific population. The question how to select the high risk population to be screened has no response by now. SPECT and stress echocardiography seem valuable for screening but not for risk stratification. A large randomized clinical trial is required to confirm the cost-utility ratio of such a screening. [less ▲]
