Adult animals can eavesdrop on behavioral interactions between potential opponents to assess their competitive ability and motivation to contest resources without interacting directly with them. Surprisingly, eavesdropping is not yet considered as an important factor used to resolve conflicts between family members. In this study, we show that nestling barn owls (Tyto alba) competing for food eavesdrop on nestmates' vocal interactions to assess the dominance status and food needs of opponents. During a first training playback session, we broadcasted to singleton bystander nestlings a simulated vocal interaction between 2 prerecorded individuals, 1 relatively old (i.e., senior) and 1 younger nestling (i.e., junior). One playback individual, the "responder," called systematically just after the "initiator" playback individual, hence displaying a higher hunger level. To test whether nestlings have eavesdropped on this interaction, we broadcasted the same prerecorded individuals separately in a subsequent playback test session. Nestlings vocalized more rapidly after former initiators' than responders' calls and they produced more calls when the broadcasted individual was formerly a junior initiator. They chiefly challenged vocally juniors and initiators against whom the likelihood of winning a vocal contest is higher. Owlets, therefore, identified the age hierarchy between 2 competitors based on their vocalizations. They also memorized the dynamics of competitors' previous vocal interactions, and used this information to optimally adjust signaling level once interacting with only 1 of the competitor. We conclude that siblings eavesdrop on one another to resolve conflicts over parental resources.

O objetivo da pesquisa foi avaliar os indicadores de risco para a hipertensão arterial em crianças e adolescentes. Estudo transversal desenvolvido com 342 indivíduos de seis a 18 anos de uma escola da cidade de Fortaleza (CE). A maioria eram homens (51,5%). A média de idade foi 11,73 anos ( 3,19). Foram freqüentes os escolares com sobrepeso / obesidade (16,8%) e com pressão arterial acima do percentil 90 (44,7%). Sedentarismo, tabagismo e etilismo estiveram presentes em 51,5%, 38% e 15,5% dos avaliados. A pressão arterial sistólica esteve correlacionada com as variáveis: idade, peso, estatura, perímetros da cintura e do quadril, prega subescapular e Índice de Massa Corporal. Houve correlação da pressão arterial diastólica com idade, peso, estatura, perímetros da cintura e do quadril. Confirma-se a influência de fatores de risco sobre os valores da pressão arterial em jovens. A pressão arterial sistólica foi especialmente influenciada por indicadores antropométricos.

In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for acomplete iterative system for the same. Our method splits the task of tonic pitch identification into two stages. In the first stage, which is applicable to both vocal and instrumental music, we perform a multi-pitch analysis of the audio signal to identify the tonic pitch-class. Multi-pitch analysisallows us to take advantage of the drone sound, which constantlyreinforces the tonic. In the second stage we estimate the octave in which the tonic of the singer lies and is thusneeded only for the vocal performances. We analyse the predominant melody sung by the lead performer in order to establish the tonic octave. Both stages are individually evaluated on a sizable music collection and are shown toobtain a good accuracy. We also discuss the types of errors made by the method.Further, we present a proposal for a system that aims to incrementally utilize all the available data, both audio and metadata in order to identify the tonic pitch. It produces a tonic estimate and a confidence value, and is iterative in nature. At each iteration, more data is fed into the systemuntil the confidence value for the identified tonic is above a defined threshold. Rather than obtain high overall accuracy for our complete database, ultimately our goal is to develop a system which obtains very high accuracy on a subset of the database with maximum confidence.

Medialization laryngoplasty was performed in 25 patients between 1993 and 1997. The underlying pathology resulting in glottal incompetence was vocal cord paralysis in 22 patients and vocal cord bowing in 3 patients. Two types of implants were used: self-carved Proplast in 19 patients and prefabricated hydroxyapatite prostheses in 6 patients. Preoperative and postoperative results were compared in terms of dysphagia, vocal quality as graded by three experienced voice specialists, and computer measurements of the glottal gap. All patients showed improvement both subjectively and on the objective measurements used. Swallowing returned to normal in all patients who had isolated recurrent laryngeal nerve paralysis. The voice improved in all patients but was rarely judged as entirely normal.

Aquest treball fa un estudi dels baixonets a Catalunya des de les perspectives organològica, funcional i del repertori. A partir de les informacions aportades pels instruments originals, pels tractats i per estudis especialitats, es defineixen una tipologia instrumental pròpiament hispànica, i unes funcions principalment relacionades amb la música vocal religiosa de mitjans del segle XVI a mitjans del segle XVIII. Posteriorment, es realitza un estudi de la música amb baixonet a la localitat de Canet de Mar. A partir del treball de camp al seu arxiu parroquial, es compilen vuit obres específiques per a baixonet, se'n transcriuen alguns manuscrits, i se'n defineixen els principals aspectes formals i funcionals. El cas de Canet de Mar es pot considerar com un exemple més o menys representatiu de la pràctica instrumental i del repertori específic del baixonet a Catalunya a finals del segle XVII i començaments del segle XVIII.

Nestling begging behaviour may be an honest signal of need used by parents to adjust optimally both feeding rate and within-brood food allocation. Although several studies showed that mothers and fathers can be differentially responsive to nestling begging behaviour with one parent showing a stronger tendency to feed the offspring that beg the most, little information is yet available on whether offspring beg for food at different intensities from the mother than father. In the present study, we investigated in nestling barn owls whether the intensity of vocal begging behaviour in the presence of the mother and in the presence of the father is different. A difference is expected because reproductive tasks are divided between the sexes with fathers bringing more food items to the nest than mothers. The results show that although mothers transfer their prey item to one of the offspring more rapidly than fathers once in their nestbox, nestlings begged more intensely in the presence of their mother than in the presence of their father. To our knowledge, this is the first empirical evidence that offspring vocalize to different levels in the presence of their mother than in the presence of their father.

OBJECTIVE: We sought to describe our experience in the management of complex glotto-subglottic stenosis in the pediatric age group. METHODS: Between 1978 and 2008, 33 children with glotto-subglottic stenosis underwent partial cricotracheal resection, and they form the focus of this study. They were compared with 67 children with isolated subglottic stenosis (no glottic involvement). The outcomes measured were need for revision open surgical intervention, delayed decannulation (>6 months), and operation-specific and overall decannulation rates. Fisher's exact test was used for comparison of outcomes. RESULTS: Results of preoperative evaluation showed Myer-Cotton grade III or IV stenosis in 32 (97%) patients and grade II stenosis in 1 patient. All patients with glotto-subglottic stenosis were treated with partial cricotracheal resection and simultaneous repair of the glottic pathology. Bilateral fixed vocal cords were seen in 19 (58%) of 33 patients, bilateral restricted abduction was seen in 7 (21%) of 33 patients, and unilateral fixed vocal cord was seen in 7 (21%) of 33 patients. Ten patients underwent single-stage partial cricotracheal resection with excision of interarytenoid scar tissue. The endotracheal tube was kept for a mean period of 7 days as a stent. Twenty-three patients underwent extended partial cricotracheal resection with LT-Mold (Bredam S.A., St. Sulpice, Switzerland) or T-tube stenting. The overall decannulation rate included 26 (79%) patients, and the operation-specific decannulation rate included 20 (61%) patients. CONCLUSIONS: Glotto-subglottic stenosis is a complex laryngeal injury associated with delayed decannulation and decreased overall and operation-specific decannulation rates when compared with those after subglottic stenosis without glottic involvement after partial cricotracheal resection.

Durante a gestação o corpo da mulher sofre muitas alterações biomecânicas como consequência das alterações fisiológicas, podendo favorecer o surgimento da lombalgia decorrente da gestação devido principalmente à acção hormonal e seus efeitos do desenvolvimento fetal e do corpo materno. A dor pode ter localização variada podendo ser desde região cervical e até a prega glútea. Foram determinadas a prevalência e os factores de risco da lombalgia em cento e duas gestantes que faziam acompanhamento pré-natal nos Centros de Saúde da Praia, por meio da aplicação de um questionário às gestantes a partir do segundo trimestre de gestação. A pesquisa foi realizada de 4 de Julho a 10 de Setembro de 2011, nas salas de espera para atendimento pré-natal dos Centros de Saúde. Foi encontrada uma prevalência de 66,7%. Conclui-se que a prevalência de lombalgia é significativa, com muitos potenciais factores de risco como execução de trabalhos domésticos, número de gestações anteriores, a idade e nível socioeconómico. Estes dados poderiam servir como base para elaboração de uma proposta de tratamento e prevenção através dos exercícios fisioterapêutico.
Characterization of intonation in Karṇāṭaka music by parametrizing context-based Svara Distributions
Resumo:
Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance to several information retrieval tasks like the development of rāga and artist similarity measures. In our previous work, we proposed a compact representation of intonation based on the parametrization of the pitch histogram of a performance and demonstrated the usefulness of this representation through an explorative rāga recognition task in which we classified 42 vocal performances belonging to 3 rāgas using parameters of a single svara. In this paper, we extend this representation to employ context-based svara distributions, which are obtained with a different approach to find the pitches belonging to each svara. We quantitatively compare this method to our previous one, discuss the advantages, and the necessary melodic analysis to be carried out in future.

Distal myopathies represent a heterogeneous group of inherited skeletal muscle disorders. One type of adult-onset, progressive autosomal-dominant distal myopathy, frequently associated with dysphagia and dysphonia (vocal cord and pharyngeal weakness with distal myopathy [VCPDM]), has been mapped to chromosome 5q31 in a North American pedigree. Here, we report the identification of a second large VCPDM family of Bulgarian descent and fine mapping of the critical interval. Sequencing of positional candidate genes revealed precisely the same nonconservative S85C missense mutation affecting an interspecies conserved residue in the MATR3 gene in both families. MATR3 is expressed in skeletal muscle and encodes matrin 3, a component of the nuclear matrix, which is a proteinaceous network that extends throughout the nucleus. Different disease related haplotype signatures in the two families provided evidence that two independent mutational events at the same position in MATR3 cause VCPDM. Our data establish proof of principle that the nuclear matrix is crucial for normal skeletal muscle structure and function and put VCPDM on the growing list of monogenic disorders associated with the nuclear proteome.

OBJECTIVE: To correlate the postoperative voice outcome to preoperative glottic involvement, following partial cricotracheal resection (PCTR) in children. The glottic involvement was analysed based on the extent of subglottic stenosis (SGS) in the endoscopic image and functional dynamic assessment using flexible endoscopy. METHODS: We conducted an interobserver study in which two ENT surgeons, blinded to one another's interpretation, independently rated the extent of SGS based on the endoscopic image along with the dynamic functional airway assessment, of 108 children who underwent PCTR for grade III or IV stenosis. Based on the observation, the glottic involvement was rated into 4 categories: Evaluation of the voice was based on a parent/patient proxy questionnaire sent in 2008 to assess the current functional status of the patient's voice. RESULTS: Among the 77 patients available for long-term outcome with a minimum 1-year follow-up, 31 patients had isolated SGS free from vocal cords (group A) and 30 had SGS reaching the under surface of vocal cords with partial or no impairment of abduction of vocal cords (group B). Twelve patients belonged to group C with posterior glottic stenosis and/or vocal cord fusion (without cricoarytenoid ankylosis) and 4 patients had transglottic stenosis and or/bilateral cricoarytenoid ankylosis (group D). The long-term voice outcome following PCTR as perceived by the parent or patient was normal in 18% (14 of 77 patients) and the remaining 63 patients demonstrated mild to severe dysphonia. Patients belonging to group A and B exhibited either normal voice or mild dysphonia. Patients in group C demonstrated dysphonia, which was moderate in severity in the majority (83%). All patients in group D with transglottic stenosis and/or CAA showed severe dysphonia. CONCLUSION: Children with associated glottic involvement are at high risk for poor voice outcome following PCTR. The severity of dysphonia was found to be proportional to the preoperative glottic involvement. Preoperative rating of the extent of glottic involvement based on endoscopic image and dynamic assessment was found to be useful in prognosticating the voice outcome.

Assessing the amount of rivals is crucial to optimally adjust investment into a contest. If laboratory animals show numerical abilities, little is known about the ecological implications particularly in young animals. The two to nine barn owl (Tyto alba) siblings vocally compete for priority of access to food resources before parents actually deliver them. In dyads, the individual that vocalizes at the highest rate in the absence of parents deters its siblings from competing for next delivered prey. We tested the novel hypothesis that to optimally adjust vocal investment, barn owl nestlings assess how many of their siblings are currently competing. To singleton owlets, we broadcasted a fixed global number of calls emitted by one, two or four pre-recorded unfamiliar nestlings. We could thus distinguish the independent effect on singletons' vocal behavior of the global number of calls produced by a brood from the number of competitors that produced these calls. Overall, nestlings retreated more from vocal contest when facing more competitors. However, in front of one highly motivated competitor, nestlings refrained from vocalizing to a larger extent than when competing against more but less motivated individuals. Therefore, young animals assess variation in the number of currently competing siblings based on individual-specific vocal cues.
