A number of commercial devices for measuring the transverse electrical conductance of the thyroid cartilage produce waveforms that can be useful for monitoring movements within the larynx during voice production, especially movements that are closely related to the time-variation of the contact between the vocal folds as they vibrate. This paper compares the various approaches that can be used to apply such a device, usually referred to as an electroglottograph, to the problem of monitoring the time-variation of vocal fold abduction and adduction during voiced speech. One method, in which a measure of relative vocal fold abduction is derived from the duty cycle of the linear-phase high pass filtered electroglottograph waveform, is developed in detail.

A variety of benign and malignant neoplasms occur in the superior cervical neck, parapharyngeal space or the infratemporal fossa. The surgical resection of these lesions may result in postoperative iatrogenic injury to the vagus nerve with associated dysfunctional swallowing and airway protection. Anatomic and functional preservation of this critical cranial nerve will contribute to a favorable surgical outcome. Fourteen patients with tumors of the cervical neck or adjacent skull base underwent intraoperative vagal nerve monitoring in an attempt to preserve neural integrity following tumor removal. Of the 11 patients with anatomically preserved vagal nerves in this group, seven patients had normal vocal cord mobility following surgery and all 11 patients demonstrated normal vocal cord movement by six months. In an earlier series of 23 patients with tumors in the same region who underwent tumor resection without vagal nerve monitoring, 18 patients had anatomically preserved vagal nerves. Within this group, five patients had normal vocal cord movement at one month and 13 patients demonstrated normal vocal cord movement at six months. This paper will outline a technique for intraoperative vagal nerve monitoring utilizing transcricothyroid membrane placement of bipolar hook-wire electrodes in the vocalis muscle. Our results with the surgical treatment of cervical neck and lateral skull base tumors for patients with unmonitored and monitored vagal nerves will be outlined.

PURPOSE: To investigate laryngeal and voice disorders in patients with gastroesophageal symptoms and their correlation with pH-monitoring. METHODS: A prospective study was carried out in patients attended at the Voice Disorder Outpatient Clinics of Botucatu Medical School in a five-year period and had vocal and gastroesophagic symptoms. Patients underwent videolaryngoscopy, auditory-perceptual vocal analyses, computerized acoustic vocal analysis and dual probe pH-monitoring for 24 hours. RESULTS: Fifty-seven patients were included (aged between 21 and 65 years; 45 women and 12 men), 18 had normal (31.6%) and 39 had abnormal pH-monitoring results (68.4%). Videolaryngoscopy recorded several laryngeal lesions for both patients with normal and abnormal pH-monitoring, but mostly for the latter group, highlighting posterior pachyderma. Auditory-perceptual vocal assessments identified vocal changes of several intensities for both groups but especially for patients with abnormal pH-monitoring results. All acoustic parameters, except f0, were abnormal for both groups, compared to the control population. CONCLUSION: Acoustic and perceptual vocal changes and laryngeal lesions were recorded for both patients with normal pH-monitoring results and patients with abnormal pH-monitoring results, evidencing the importance of clinical history and videolaryngoscopic findings for diagnosing acid laryngitis.

Current knowledge regarding the vocal behavior in tropical non-passerines is very limited. Here, we employed passive acoustic monitoring to study the vocal activity of the white-tipped dove (Leptotila verreauxi) at three sites over a year in the Brazilian Pantanal. The diel pattern of vocal activity showed a bimodal pattern, with significantly higher vocal activity after sunrise than during the other hours of the day, in agreement with prior studies on this species and other members of Columbidae. The species was vocally active throughout the year, but vocal activity was maximum during May-June and lowest during January-February. Relative air humidity was positively associated with vocal activity, which may be related to the improvement of sound transmission under more humid conditions, but it could also be related to foraging efficiency due to a higher availability of invertebrates on wetter days. Vocal activity was not related to the mean air temperature or daily rainfall. Acoustic monitoring proved to be a useful tool for monitoring this shy forest species, for which a minimum number of three monitoring days was needed to detect a reliable vocal activity rate. Future studies should evaluate its use for monitoring other species of doves and pigeons that are secretive or threatened.

CONTEXT AND OBJECTIVE: Intraoperative nerve monitoring has emerged as a valuable tool to facilitate recurrent laryngeal nerve identification during thyroid surgery, thereby avoiding its injury. The aim was to evaluate vocal fold mobility in patients who underwent thyroidectomy with intraoperative nerve monitoring. DESIGN AND SETTING: Cohort formed by a consecutive series of patients, at a tertiary cancer hospital. METHODS: The subjects were patients who underwent thyroidectomy using intraoperative laryngeal nerve monitoring, between November 2003 and January 2006. Descriptive analysis of the results and comparison with a similar group of patients who did not undergo nerve monitoring were performed. RESULTS: A total of 104 patients were studied. Total thyroidectomy was performed on 65 patients. Vocal fold immobility (total or partial) was detected in 12 patients (6.8% of the nerves at risk) at the first postoperative evaluation. Only six (3.4% of the nerves at risk) continued to present vocal fold immobility three months after surgery. Our previous series with 100 similar patients without intraoperative nerve monitoring revealed that 12 patients (7.5%) presented vocal fold immobility at the early examination, and just 5 (3.1%) maintained this immobility three months after surgery, without significant difference between the two series. CONCLUSION: In this series, the use of intraoperative nerve monitoring did not decrease the rate of vocal fold immobility.

Chaco Chachalaca ( Ortalis canicollis) is a declining Neotropical bird, for which our current knowledge about its natural history is very limited. Here, we evaluated for first time the utility of passive acoustic monitoring, coupled with automated signal recognition software, to monitor the Chaco Chachalaca, described the vocal behavior of the species across the diel and seasonal cycle patterns, and proposed an acoustic monitoring protocol to minimize error in the estimation of the vocal activity rate. We recorded over a complete annual cycle at three sites in the Brazilian Pantanal. The species was detected on 99% of the monitoring days, proving that this technique is a reliable method for detecting the presence of the species. Chaco Chachalaca was vocally active throughout the day and night, but its diel activity pattern peaked between 0500 and 0900. The breeding season of Chaco Chachalaca in the Brazilian Pantanal, based on seasonal changes in vocal activity, seems to occur during the last months of the dry season, with a peak in vocal activity between August and October. Our results could guide future surveys aiming to detect the presence of the species, both using traditional or acoustic surveys, or to evaluate changes in population abundance using passive acoustic monitoring, for which recorders should be left in the field for a minimum period of nine days to obtain a low-error estimate of the vocal activity of the species. Our results suggest that passive acoustic monitoring might be useful, as a complementary tool to field studies, for monitoring other cracids, a family with several threatened species that are reluctant to human presence.

Objectives: Recurrent laryngeal nerve (RLN) palsy constitutes one of the dreaded complications of thyroid surgery. Sequelae of RLN injury may affect quality of life and can sometimes be life threatening. Pre-, intra-, and post- operative monitoring of the RLN is desirable for safe thyroid surgery. Surgeon-performed transcutaneous laryngeal ultrasound (TLUS) may become a substitute for laryngoscopy in the evaluation of vocal cords after thyroidectomy and may be used for prognostic correlation of intraoperative neurophysiologic monitoring (IONM). In this study, a retrospective cohort of patients who underwent thyroidectomy with monitoring of the RLN by intermittent IONM (I-IONM) was subjected to post-operative ultrasound assessment of vocal cords for the evaluation of RLN integrity. Material and Methods: This was a prospective study of a retrospective cohort in a tertiary care endocrine surgery unit. Fifty-six patients who underwent thyroidectomy with RLN monitoring from March 2017 to March 2019 were analyzed. Patients were analyzed during follow-up either when they arrived at the endocrine surgery outpatient department or through a telephone call. All patients underwent pre-operative laryngoscopy, intraoperative monitoring with I-IONM and Nerve Integrity Monitor 3.0 monitor, and post-operative TLUS evaluation of vocal cords. Results: Of the 56 patients evaluated in this study, 112 vocal cords and 102 nerves at risk were analyzed. The incidence of vocal palsy was 7.84%. The sensitivity of ultrasonography for vocal cord analysis was 85%, specificity was 95.23%, positive predictive value was 85%, and negative predictive value was 95.23% in that series. The vocal cord visualization rate was 93.5%. Conclusion: Surgeon-performed ultrasound may be used to assess RLN integrity in post-thyroidectomy patients to enhance post-operative care.

To cultivate students’ artistic quality, enhance their vocal music quality, and prepare them to make great contributions to the innovation and development of my country’s vocal music art is the main goal of opening vocal music performance major in colleges and universities. With the advancement of technology and the demands of talent development, the vocal music teaching methodology for the vocal music performance major in colleges and universities must be continuously enhanced. Otherwise, there will be an issue of disconnect between teaching style and talent development, which will harm both the development of high-quality vocal music talents and the innovation and growth of vocal music performance majors in colleges and universities. The vocal music performance major at colleges and universities should actively support the reform and innovation of the vocal music teaching mode in order to extend students’ knowledge, develop their all-around ability, and provide a strong foundation for vocal music performance, to develop students’ all-encompassing musical abilities. This research suggests a design strategy for the monitoring and model optimization of the teaching environment for vocal performance majors from the standpoint of core literacy. To increase the efficiency and objectivity of course instruction, cluster analysis aids students in categorising and searching for vocal music performance main repertoire as well as using collaborative filtering recommendations to locate their own vocal music performance. The simulation test analysis is completed lastly. The method has a certain accuracy, which is 7.59% higher than the conventional algorithm, according to the simulation findings. In addition to significantly increasing student interest in studying vocal music performance courses, we further reform and innovation of the teaching method for these courses at colleges and universities can also strengthen students’ understanding of various repertoire styles and significantly enhance their musical literacy.

Many common voice disorders are chronic or recurring conditions likely to result from faulty and/or abusive patterns of vocal behavior. Such behaviorally based disorders can be difficult to assess accurately in the clinical setting and potentially could be much better characterized by long-term ambulatory monitoring of vocal function as individuals engage in their typical daily activities. Ambulatory monitoring also could provide new insight into the actual role of voice use in common disorders and missing quantitative data on what constitutes normal levels of daily voice use for different groups of individuals, activities, and occupations. This report describes the motivation, previous development efforts, current state-of-the-art technology, and future directions in ambulatory monitoring of voice use.

There is an abundance of bird species in subtropical areas, but studies on the vocal behavior of non-passerines in subtropical regions are limited. In this study, passive acoustic monitoring was used to investigate the temporal acoustic patterns of the vocal activities of the Oriental Turtle Dove (Streptopelia orientalis) in Yaoluoping National Nature Reserve (YNNR) in eastern China. The results show that the vocal production of the Oriental Turtle Dove exhibited a seasonal variation, peaking in the period April–August. Additionally, its diurnal vocal activity displayed a bimodal pattern in late spring and summer, with the first peak in the morning and a secondary peak at dusk. Among weather factors, temperature significantly affected the temporal sound pattern of the Oriental Turtle Dove, instead of humidity and precipitation. This study, which was focused on sound monitoring technology, provides knowledge for further research on bird behavior and ecology. In the future, long-term sound monitoring could be used for managing and conserving bird biodiversity.

This thesis explores a concept by Sonvox AB called VoiceUp. The concept is that of a mobile application that communicates with a wearable voice measuring device and visualizes voice information in a way that helps singers. Sonvox current main product is VoxLog—a system for long-term voice monitoring, mostly used for research purposes. Sonvox believes that their voice analysis technology could be relevant to a larger audience. The main goal for the thesis is to explore if a wearable voice measuring device could be relevant to singers, and in what ways. To do this, a needs analysis was conducted where song teachers and singers were interviewed. In order to draw statistical conclusions about the occurrence of needs, a survey was conducted where people with an interest for singing were the targeted respondents. Based on the result from the needs analysis, the VoiceUp concept was refined, resulting in an idea of a product that measures and visualizes how much the user sings and speaks with the aim to increase singers motivation to practice singing more regularly. Based on theory related to self-tracking, a design proving the concept was created, resulting in a mockup and a simple prototype. The mockup and the prototype can together be seen as one example of how self-tracking technology could be relevant to singers.

Quantificar e qualificar o bem-estar de animais de produção, ainda é um desafio. Em qualquer avaliação de bem-estar, deve-se analisar, principalmente, a ausência de sentimentos negativos fortes, como o sofrimento, e a presença de sentimentos positivos, como o prazer. O objetivo principal dessa pesquisa foi quantificar a vocalização de suínos em grupos sob diferentes condições térmicas. Em termos de objetivos específicos foram avaliar a existência de padrões vocálicos de comunicação entre animais alojados em grupo e extrair as características acústicas dos espectros sonoros das vocalizações relacionando com as diferentes condições do micro-clima da instalação. O experimento foi realizado em uma unidade de experimentação com suínos, junto à University of Illinois (EUA), com ambiente controlado. Quatro grupos de seis leitões foram utilizados para a coleta dos dados. Foram instalados dataloggers para registrar as variáveis ambientais (T, °C e UR, %) e posterior cálculo dos índices de conforto (ITU e Entalpia do ar). Foram instalados microfones do tipo cardióide no centro geométrico de cada baia que abrigava os leitões, para registro das vocalizações. Os microfones foram conectados a um amplificador de sinais, e este a uma placa de captura dos sinais de áudio e vídeo, instalados em um computador. Para as edições dos arquivos de áudio contendo as vocalizações dos leitões, o programa Goldwave® foi utilizado na separação, e aplicação de filtros para a retirada de ruídos. Na sequência, os áudios foram analisados com auxílio do programa Sounds Analysis Pro 2011, onde foram extraídos as características acústicas. A amplitude (dB), frequência fundamental (Hz), frequência média (Hz), frequência de pico (Hz) e entropia foram utilizados para caracterização do espectro sonoro das vocalizações do grupo de leitões nas diferentes condições térmicas. O delineamento do experimento foi em blocos casualizados, com dois tratamentos, e três repetições na semana, sendo executado em duas semanas. Os dados foram amostrados para uma análise do comportamento do banco de dados de vocalização em relação aos tratamentos que foram aplicados. Os dados foram submetidos a uma análise de variância utilizando o proc GLM do SAS. Dentre os parâmetros acústicos analisados, a amplitude (dB), frequência fundamental e entropia. Os tratamentos, condição de conforto e condição de calor, apresentaram diferenças significativas, pelo teste de Tukey (p<0,05). A análise de variância mostrou diferenças no formato da onda para cada condição térmica nos diferentes períodos do dia. É possível quantificar a vocalização em grupos de suínos em diferentes condições térmicas, por intermédio da extração das características acústicas das amostras sonoras. O espectro sonoro foi extraído, indicando possíveis variações do comportamento dos leitões nas diferentes condições térmicas dentro dos períodos do dia. No entanto, a etapa de reconhecimento de padrão, ainda necessita de um banco de dados maior e mais consistente para o reconhecimento do espectro em cada condição térmica, seja por análise das imagens ou pela extração das características acústicas. Dentre as características acústicas analisadas, a amplitude (dB), frequência fundamental (Hz) e entropia das vocalizações em grupo de suínos foram significativas para expressar a condição dos animais quando em diferentes condições térmicas.To quantify and to qualify animal well-being in livestock farms is still a challenge. To assess animal well-being, it must be analyzed, mainly, the absence of strong negative feelings, like pain, and the presence of positive feelings, like pleasure. The main objective was to quantify vocalization in a group of pigs under different thermal conditions. The specific objectives were to assess the existence of vocal pattern of communication between housing groups of pigs, and get the acoustic characteristics of the sound spectrum from the vocalizations related to the different microclimate conditions. The trial was carried out in a controlled environment experimental unit for pigs, at the University of Illinois (USA). Four groups of six pigs were used in the data collection. Dataloggers were installed to record environmental variables (T, °C and RH, %). These environmental variable were used to calculate two thermal comfort index: Enthalpy and THI. Cardioid microphones were installed to record continuous vocalizations in the geometric center of each pen where the pigs were housing. Microphones were connected to an amplifier, and this was connected to a dvr card installed in a computer to record audio and video information. For doing the sound edition in a pig vocalization database, the Goldwave® software was used to separate, and filter the files excluding background noise. In the sequence, the sounds were analyzed using the software Sounds Analysis Pro 2011, and the acoustic characteristics were extracted. Amplitude (dB), pitch (Hz), mean frequency (Hz), peak frequency (Hz) and entropy were used to characterize the sound spectrum of vocalizations of the groups of piglets in the different thermal conditions. A randomized block design was used, composed by two treatments and three repetitions in a week and executed in two weeks. Data were sampled to analyze the behavior of the databank of vocalization as a relation to the applied treatments. Data were submitted to an analysis of variance using the proc GLM of SAS. Among the studied acoustic parameters, the amplitude (dB), pitch and entropy. The treatments (comfort and heat stress conditions) presented significative differences, through Tukey\'s test (p<0,05). The analysis of variance showed differences to the wave format to each thermal condition in the different periods of the day. The quantification of vocalization of swine in groups under different thermal conditions is possible, using the extraction of acoustic characteristics from the sound samples. The sound spectrum was extracted, which indicated possible alterations in the piglets behavior in the different thermal conditions during the periods of the day. However, the stage of pattern\'s recognition still needs a larger and more consistent database to the recognition of the spectrum in each thermal condition, through image analysis or by the extraction of the acoustic characteristics. Among he analyzed acoustic characteristics, the amplitude (dB), pitch (Hz) and entropy of the vocalizations of groups of swine were significative to express the condition of the animals in different thermal conditions.

Les hallucinations auditives verbales (HAVs) sont des perceptions langagières en l'absence de stimuli externes appropriés. Elles sont un des symptômes les plus invalidants dans la schizophrénie. Parmi les grands types de modèles explicatifs, deux sont particulièrement intéressants : les modèles à origine perceptive, selon lesquels les voix entendues seraient dues à une imagerie mentale et des représentations auditives trop vives et les modèles à origine productive, selon lesquels la parole intérieure est perturbée de telle sorte que les propres pensées verbales du patient sont attribuées à un agent externe. Pour tester le versant moteur des modèles productifs, une expérience de recueil de traces oro-faciales lors des HAVs à l'aide de l'électromyographie de surface a été conduite auprès de patients schizophrènes. Les résultats montrent une tendance à l'augmentation de l'activité musculaire des orbiculaires de la bouche lors des HAVs par rapport à une condition de repos. Pour tester le versant cérébral des modèles, une expérience d'imagerie cérébrale par IRMf lors de tâches de génération de pensée verbale et de perception auditive a été menée auprès de sujets schizophrènes et sujets contrôles et a évoqué une hyper-activation d'un réseau impliquant le cortex temporal et le cortex cingulaire antérieur qui reste à confirmer. La caractérisation phénoménologique des HAVs vécues par les patients a montré que les HAVs diffèrent de la pensée intérieure typique en ce que les voix entendues peuvent être nombreuses et ne sont pas celle du patient lui-même. Ainsi aucun des deux types de modèles considérés isolément n'est satisfaisant pour expliquer les HAVs. Un modèle intégratif multidimensionnel est proposé qui permettrait de mieux rendre compte de la complexité des HAVs. Il existerait, chez les patients schizophrènes une prédisposition perceptive hyper-active couplée à un système de prédiction défaillant. Les deux dysfonctionnements seraient de plus modulés par des facteurs attentionnels, de stress et par un biais cognitif d'externalisation.

La compréhension des sociétés, de la communication et de la cognition chez les primates non humains permet de mieux comprendre l'évolution de notre propre espèce. Bien que la structure acoustique chez les primates soit principalement innée, leur utilisation vocale et leur compréhension / réponse sont plus flexibles et fluctuent en fonction des expériences sociales. Comme les relations peuvent varier entre les individus d’un même groupe et changer avec le temps, les contextes d’utilisation des vocalisations (perspective du signaleur) et les schémas de réponse aux vocalisations (perspective du récepteur) sont supposés différer même entre espèces très proches.
Mon projet de thèse s'inscrit dans le cadre actuel déterminant dans quelle mesure le système social façonne la communication et la cognition sociale chez les primates. Plus spécifiquement, j’ai étudié l’utilisation d’une vocalisation affiliative — le grognement — et la surveillance sociale d’une population sauvage de babouins de Guinée (Papio papio) vivant dans le parc national du Niokolo Koba, au Sénégal. En combinant des observations comportementales et des designs expérimentaux, je me suis attachée à investir le point de vue du signaleur et du receveur en utilisant le grognement, la vocalisation affiliative la plus commune chez les babouins. Les babouins de savane (P. ursinus, P. cynocephalus, P. kinda, P. anubis) vivent dans des groupes polygynandres caractérisés par une forte compétition entre males et des relations sociales stables entre femelles. A l’inverse, l’organisation sociale des babouins de Guinée et hamadryas (P. hamadryas) est caractérisée par une société à plusieurs niveaux, une dispersion majoritaire des femelles et un système reproductif polygyny-monandre. Chez le babouin de Guinée, « l’unité » — i.e., un mâle « primaire », 1-6 femelle, leur progéniture, et fréquemment des mâles « secondaires » — représente le cœur de la société, et l’agglomération de plusieurs unités s’appelle le « parti ». Les mâles sont majoritairement philopatriques au sein d’un parti et partage une grande tolérance spatiale, facilitant la formation de liens sociaux forts et durables.
Afin d’évaluer si le système social du babouin de Guinée influence leur utilisation du grognement, j’ai collecté des observations comportementales de mâles et de femelles sexuellement matures. Tout d’abord, j'ai examiné si la nature des interactions suite à une approche était modulée par la production de grognements par l'animal approchant (i.e., le sujet). A la suite d’une approche avec grognement chez les deux sexes, la dyade était plus susceptible d’interagir de manière affiliative. De plus, les grognements augmentaient la probabilité de manipulation du nourrisson du partenaire et réduisaient le risque de supplantation. Par la suite, j'ai testé comment un nourrisson à proximité du receveur et la qualité des liens sociaux entre partenaires pouvaient potentiellement influencer la décision du sujet à grogner ou rester silencieux. Les deux sexes étaient plus susceptibles de grogner envers un partenaire féminin que masculin. Entre femelles, la probabilité d’émission vocale était plus faible lorsqu’elles partageaient de forts liens sociaux, et ceci uniquement en présence d’un nourrisson avec sa partenaire. L’appartenance à une unité a également eu un impact sur le grognement, car les femmes étaient plus susceptibles de vocaliser lorsqu'elles approchent une femme d'une autre unité. Le statut de dominance et l’écart entre rang hiérarchique dyadique n’altéraient pas la probabilité de grognement entre femelles, même si une hiérarchie de dominance linéaire a été démontrée. En accord avec la tolérance élevée chez les mâles de cette espèce, la force des liens sociaux n'a eu aucun impact sur la probabilité de grogner lors d'approches entre mâles. Enfin, les mâles étaient plus prompts à grogner lorsqu'un nourrisson était à proximité du partenaire féminin. Dans l’ensemble, ces résultats indiquent que les babouins de Guinée utilisent les grognements de manière stratégique pour faire connaître leurs intentions bénigne lors de situations imprévisibles spécifiques (par exemple, en s’approchant d’un partenaire non préférentiel). Bien que les contraintes génétiques limitent la structure et l'étendue du répertoire vocal au sein d’un même taxon, les babouins peuvent adapter leur utilisation vocale de manière flexible en fonction de leur environnement social.
Dans une seconde étude, j'ai exploré le point de vue du receveur en testant l'attention portée aux interactions sociales de tiers chez les mâles adultes babouins de Guinée. J'ai pratiqué des expériences de repasse pour déterminer si les mâles suivaient les associations actuelles entre mâles et femelles au sein de leur parti (mais en dehors de leur propre unité). Tout d’abord, j'ai démontré que les grognements sont exprimés plus fréquemment entre femelles et mâles primaires d'une même unité que d'unités différentes. Par la suite, j'ai réalisé des séquences acoustiques congruentes et incongrues simulant un échange de grognements entre une femelle et un mâle primaire appartenant respectivement à la même unité ou non. J’ai testé ces séquences de grognements sur des mâles primaires et des mâles non primaires, comme le statut des mâles (association avec une femelle) pourrait influencer la valeur des informations sociales. Étonnamment, les babouins mâles regardaient plus longtemps vers le hautparleur lorsqu’ils étaient exposés à la condition congruente par rapport à la condition incongrue, un résultat opposé à une précédente expérience de repasse chez le mâle babouin chacma. De plus, les mâles primaires réagissaient plus fortement que les mâles non primaires, quel que soit la condition expérimentale. Ainsi, ces résultats révèlent comment les différences du système reproductif et du degré de compétition entre mâles affectent la valeur allouée aux informations sociales même entre espèces génétiquement proches.
En comparant mes résultats avec la littérature chez les geladas et d’autres espèces de babouins, les variations observées lors de l'utilisation de vocalisations et la motivation à suivre les interactions des autres chez les babouins de Guinée sont susceptibles d'être liées à des caractéristiques propres à leur système social. Bien que les babouins de Guinée utilisent des grognements de manière stratégique pour signaler leur intention bienveillante, comme c’est le cas chez plusieurs autres espèces de primates, l’absence de significativité de la force des liens sociaux entre males et males-femelles, ainsi que de la hiérarchie de dominance féminine sur la production de grognements pourrait être liée au faible niveau de compétition observé à la fois entre ou au sein d’un même sexe chez cette espèce. Compte tenu du faible intérêt que suscitent les enregistrements simulant des associations incongrues entre femelles et mâles, mes expériences de repasse supportent que l'attribution de l'attention sociale — et potentiellement l’étendue des connaissances sociales — dépend fortement du système reproductif et du degré de compétition/tolérance entre congénères. De futures recherches devraient considérer un ensemble de mesures révélant comment la compétition, la cohésion et la coopération impact potentiellement l’évolution de la communication et de la cognition. De plus, le développement de recherches comparatives entre espèces ou populations confrontées à des fluctuations des différentes dimensions du système social est primordial, sachant que l’environnement social semble expliquer davantage de variation entre espèces que les relations génétiques

Beeman, Shellie A. "Perceptions of voice teachers regarding the teaching and monitoring of students' vocal behaviors as students sing and speak : recommendations for prevention and rehabilitation within the voice studio." 2014. http://liblink.bsu.edu/uhtbin/catkey/1744487.

The purpose of this study was to identify the perceptions of voice teachers regarding the degree to which they believe they teach and monitor healthy vocal behaviors among their students as they sing and speak. Participants for the study were college/university voice professors who were members of the College Music Society and listed in its Directory of Music
Faculties in Colleges and Universities, U.S. and Canada, 2012-2013 Edition. Online, survey
research procedures and a researcher-generated questionnaire were utilized for data collection purposes. Results indicated that an overwhelming majority of participants believed there to be a relationship between the health of one’s singing voice and the health of one’s speaking voice. Participants’ perception scores were the most positive for variable MBSi, or the degree to which they believe they monitor the vocal behaviors of students when singing. Participants’ perception
scores for variable TVB, the degree to which they believe they teach healthy vocal behaviors to students, and variable MBSp, the degree to which they believe they monitor the vocal behaviors of students when speaking, ranked second and third respectively. Perception scores for variable
TVB were primarily associated with participants’ familiarity with vocal rehabilitation techniques, gender, and participants’ familiarity with the McClosky Technique. Perception scores for variable MBSi were primarily associated with participants’ familiarity with vocal
rehabilitation techniques, gender, type of student taught, and whether participants had instructed a student with a vocal disorder. Perception scores for variable MBSp were correlated with the greatest number of characteristics, including participants’ familiarity with vocal rehabilitation
techniques, participants’ familiarity with the McClosky Technique, type of student taught, years of teaching experience, and whether participants had instructed a student with a vocal disorder. The researcher concluded that, while many voice teachers understand the relationship
between the health of the speaking voice and the health of the singing voice and use various methods within their private studios to work with injured voices, voice teachers and students may not understand, nor be adequately prepared to prevent and intervene when it comes to issues of the speaking voice. In fact, the researcher concluded that there seems to be a disconnect among teachers and students alike when it comes to teaching and understanding healthy vocal
behaviors and applying them to the speaking voice. Multiple resources exist, however, in the form of various certifications, symposiums, and workshops, through which voice teachers may avail themselves of the knowledge necessary to care for the overall health of their students’ speaking and singing voices. Indeed, the voice teacher is obligated to teach well-rounded, healthy vocal behaviors, applying them to both the singing voice and the speaking voice. As
medical professionals more frequently reach out to voice teachers, voice teachers will have increased opportunity to assume a more active role on a voice care team. Because so many teachers already implement methods found within the McClosky Technique, if used with understanding and commitment, the Technique could be a means for habilitation, prevention, and intervention on behalf of students suffering from speaking voice disorders within the voice studio.Access to thesis permanently restricted to Ball State community only.

This chapter discusses American composer Eric Nathan’s Forever Is Composed of Nows (2011). This hauntingly lovely setting is simple enough to be tackled by beginners, but all singers will find it a rewarding vehicle. Nathan demonstrates conclusively that ‘less is more’. With admirable economy of language and structure, he captures and matches the pith and essence of the succinct texts with unerring musicality, so that every phrase tells. The voice is given every chance to hone each fragment to perfection, monitoring every morsel of sound, paying close attention to colour, nuance, and subtly graded dynamics. The musical style, a fluent and intuitive fusion of past and present, is reminiscent of late romanticism, evoking in particular the rarefied atmosphere of French music.

Paranasal sinuses anatomy is paired in 4 parts which includes frontal, maxillary, ethmoid, and sphenoid. Their relevant function is to secrete mucous for moisture, humidify inspired air, impart vocal resonance, and act as shock absorber for intracranial contents. Retention of secretions in the nasal cavity and sinuses can cause inflammation of the mucosa of paranasal sinuses and lead to infection. Classification of sinusitis is based on duration of symptoms. Diagnosis can be achieved clinically, however other diagnosis modalities such as cultures or radiology can help to achieve accurate diagnosis. Depending on the etiology management can be supportive or pharmacological. In some cases, long term monitoring and prevention therapy may be required.

This chapter discusses the physiological changes that occur in the last weeks and days of life, and how this understanding can help in providing better care for patients and families. Starting in the last months of life with an accelerating course in the last several weeks, patients with advanced illnesses typically develop a characteristic decline in their physical function, nutritional status, respiratory function, and cognition as a result of progressive cancer and acute symptomatic complications. These changes correspond with worsening performance status, anorexia-cachexia, breathlessness, and delirium, which are prognostic factors in patients with advanced illnesses. In the last days of life, other physiological changes involving the neurological, neuromuscular, cardiovascular, and respiratory systems become apparent. The presence of telltale signs such as non-reactive pupils, Cheyne–Stokes breathing, inability to close eyelids, grunting of vocal cords, respiration with mandibular movement, death rattle, drooping of nasolabial fold, pulselessness of radial artery, hyperextension of neck, and decreased urine output significantly increase the likelihood of impending death within 3 days, although the absence of these signs cannot rule out impending death. Physiological monitoring such as vital signs, phase angle, cardiac electrophysiology, and bispectral index may provide further insights into the dying process.

Although medical services in aviation have evolved over years based on our understanding of physiology, advancement in monitoring technology but airway management was only recently studied with a focus on space environment. The barometric pressure of ambient air declines as altitude increases, while the volume of air in a confined space will increase according to Boyle law, and therefore oxygen concentration remains at a constant 21%. Altitude sensitive equipment includes endotracheal and tracheostomy cuffs, pneumatic anti shock garments, air splints, colostomy bags, Foley catheters, orogastric and nasogastric tubes, ventilators, invasive monitors, and intra-aortic balloon pumps. The microgravity reduces the body compensation capacity for hemorrhage, while the redistribution of the blood can affect intubation by causing facial edema. Another change is the decreased gastric emptying during aviation. Acute respiratory failure, hypoxemia or inadequate ventilation and protection of the airway in a patient with impaired consciousness are common indications for advanced airway management in aviation. Airway management requires adequate training to maintain excellent medical care during aviation. Tracheal intubation using laryngoscopy would be difficult in microgravity, since the force exerted by the laryngoscope causes the head and neck move out of the field of vision by lever effect exerted on the head and generated through the laryngoscope blade by hand generating a lack of stability, resulting in the difficulty to insert the tracheal tube. While on the ground with the help of gravity, an adequate positioning of the patient is facilitated to achieve alignment of the laryngeal, pharyngeal and oral axes, which is known as sniffing position that allows visualization of the vocal cords and supraglottic structures allowing the introduction of an endotracheal tube.

Visually impaired people need help to travel safely. To make this possible, many travel aids have been designed. Among them, the cane which is considered as a symbol of visual deficiency in the whole world. In this work, we build an electronic white cane using sensors' technology. This intelligent cane detects obstacles within 2m on the ground or in height, and sends vocal instructions via a Bluetooth headset. We have also built a mobile application to track in real time the visually impaired and a WEB application to control the access to the mobile one. We use ultrasound, IR sensors and a raspberry pi to process data. We use Python as programming language for electronic devices. The mobile application is Android. Though, the WEB application is a REST API developed using Python and Java Script.
