El objetivo de este trabajo es determinar las características básicas de la entonación de los eslóganes publicitarios tanto de radio como de televisión. Con este propósito se analizan los valores de la Fº de las vocales que aparecen en el fragmento que corresponde al eslogan. Para evitar en la medida de lo posible las diferencias que pueden venir determinadas por el soporte físico en el que aparecen los eslóganes publicitarios, se escogió el mismo producto, diferentes marcas de vehículos, y se seleccionaron aquellos enunciados óptimos para un posterior análisis de la señal. Para la segmentación de los eslóganes dentro de los enunciados publicitarios y el análisis de las curvas melódicas se utilizó el programa PRAAT. Para cada enunciado se han ido anotando los valores de la F0 de cada vocal, teniendo en cuenta las tres partes de cada unidad melódica: el anacrusis, el cuerpo y la inflexión final. Para minimizar las variaciones debidas al tono de voz característico de cada locutor, se ha procedido a una estandarización de los valores frecuenciales. Los resultados obtenidos muestran que todos los eslóganes analizados presentan énfasis, que a veces afecta a una parte del contorno (anacrusis, cuerpo e inflexión final), a veces a más de una y otras, incluso a todo el contorno. Aunque en radio y televisión se suelen presentar características prosódicas similares, existen características propias del medio de comunicación que se utiliza.

Mimicry is a central plank of the emotional contagion theory; however, it was only tested with facial and postural emotional stimuli. This study explores the existence of mimicry in voice-to-voice communication by analyzing 8,747 sequences of emotional displays between customers and employees in a call-center context. We listened live to 967 telephone inter-actions, registered the sequences of emotional displays, and analyzed them with a Markov chain. We also explored other propositions of emotional contagion theory that were yet to be tested in vocal contexts. Results supported that mimicry is significantly present at all levels. Our findings fill an important gap in the emotional contagion theory; have practical implications regarding voice-to-voice interactions; and open doors for future vocal mimicry research.

We present a 53-year-old man with a vocal cord paralysis observed as a primary manifestation of lung carcinoma. Tc-99m MDP whole body bone scan was performed and resulted in a normal scintiscan. The bone scan did not reveal any suspicious foci of uptake. The possibility of bone metastasis was taken into consideration. A whole body F18-FDG-PET scan showed intense uptake in the left upper lung corresponding to the primary tumor. A bronchial biopsy confirmed infiltration by small cell lung carcinoma (SCLC). SCLC is composed of poorly differentiated, rapidly growing cells with diseases usually occurring centrally rather than peripherally. It metastasizes early. The whole-body F18-FDG-PET scan clearly demonstrated a focus of increased uptake in the second lumbar vertebral body suspicious for osteolytic metastasis. A lytic bone metastasis was confirmed by MRI. The patient then received therapy and underwent follow up abdominal CT. The scan showed blastic changes in the L2 vertebra suggesting response to treatment.

This article looks at the musical activity carried out at Palafrugell Music School as a musical education centre over the past forty years. After giving a brief description of the work carried out there by vocal and instrumental groups, the article analyses and offers examples and tangible motives that use activities to show that forming part of a coral or instrumental group helps personal development and promotes the acquisition of habits, alongside musical training and learning. In short, an education in values

The theme of this thesis is the learning process that occurs when teachers become professional voice users. The aim is to explore what it (really) means to become a professional voice user in a teaching profession; thereby developing an understanding of how future education in this field can be arranged so as to both effectively prevent vocal problems and to develop oral didactical competence among teachers. The ambition is to describe, interpret, and understand the learning process through a combination of emic and ethic research perspectives. The theoretical frame of reference reflects the cross disciplinary character of the thesis. Voice problems are common among both student teachers and inservice teachers and adversely affect professional competence, identity and quality of life. Additionally, vocal problems are proven to have a negative impact on pupils´ learning. The individual elements of learning are explored in the light of experiential learning theory and transformative learning theory. The social elements of learning are explored in relation to the theory of situated learning. In addition, theories of teacher professionalisation in terms of competence and identity are outlined. The empirical study has a longitudinal and multi method character. It is anchored in a phenomenological hermeneutical tradition, more specifically in narrative inquiry. The point of departure is the learning experiences of ten student teachers, who attended a ten week long course on voice production as part of their teacher training at Åbo Akademi University, in the autumn of 2002 and the spring of 2003. Four interviews in the form of conversations were conducted with each participant. These were crystallised with a process diary, a Swedish Voice Handicap Index, a voice observation, and a video observation. A fifth interview was conducted with each participant five years post teacher training, in the spring of 2008. Participant observation was also conducted throughout the course. The research materials have been analysed and interpreted narratively using a phenomenological hermeneutical method. The results are presented descriptively as individual narratives, which are reflected in logopedic research materials. Learning is here understood as emergent awareness. This is followed by a meta narrative concerning learning as experiences in the four dimensions body, thought, feeling, and relation. Finally, interpretation is expressed with respect to the theory of relational education. Learning is here understood as a movement in the field between the actual and the possible voice. It is also viewed as fundamentally rooted in inter-human relationships, in moments of presence and coexistence. As a tentative answer to the call for an existential space for learning in order to be a professional voice user, I suggest the concept of a learning refuge as a locus for a learning process built on trust, mutuality and openness.

A musically stimulating nvironment is of great significance when considering the opportunities for development and learning that are offered to children in day nurseries. Moreover, the quality of musical activities also has great significance for the musical development of growing children. Young children are always striving to create meaning and understanding; they influence and are influenced by the context in which they are situated. The purpose of this study is to investigate the planned music activities in the musical learning environment of seven toddler’s groups in day nurseries, based on four different aspects: the texts of children’s songs, the melodies of children’s songs, the basic elements of music and the use of instrumentation. The data has been gathered by video observation of the planned music activities. The age of the children studied ranged from 11 months to 3 years and 11 months, and on average there were 13 children in each group. The study involved a total of just over 90 children and nine educators. The methodological approaches are hermeneutic as well as videographic, and they are applied to the analysis as required. The approaches are well suited to an understanding of the planned music activities where the individual’s communications and actions are studied. The results of the study show that educators impart a cultural heritage to the children in the form of old traditional songs, but they also act as intermediaries for newer children's songs. They focus on actively on the text content of the children’s songs in their interaction with the children, but do not address the meaning of the text. Furthermore, while the educators use music sessions for the children to develop, among other things, an understanding of language and social skills, they do not use the sessions to develop the children’s musical skills. The educators could, to a much greater extent than they now do, direct the children's attention to the basic elements of music, and conduct meta-cognitive dialogues with the children. They use a large repertoire of children's songs, which are, however, often too demanding for the children’s voices to cope with. In addition, the educators do not plan, in any significant way, activities for the toddlers in order to help them develop the accuracy of their vocal tones. With regard to the use of instruments, the educators focus, in their interaction with the children, is placed on both the usage of the instruments and knowledge about the instruments. Regarding the use of instruments the study shows that the children’s musical expression takes place in an environment that includes both melody and rhythm instruments. It is clear that children are actively interested in the constructed instrument environment, because for long periods of time they independently play and experiment with instruments.

Among the challenges of pig farming in today's competitive market, there is factor of the product traceability that ensures, among many points, animal welfare. Vocalization is a valuable tool to identify situations of stress in pigs, and it can be used in welfare records for traceability. The objective of this work was to identify stress in piglets using vocalization, calling this stress on three levels: no stress, moderate stress, and acute stress. An experiment was conducted on a commercial farm in the municipality of Holambra, São Paulo State , where vocalizations of twenty piglets were recorded during the castration procedure, and separated into two groups: without anesthesia and local anesthesia with lidocaine base. For the recording of acoustic signals, a unidirectional microphone was connected to a digital recorder, in which signals were digitized at a frequency of 44,100 Hz. For evaluation of sound signals, Praat® software was used, and different data mining algorithms were applied using Weka® software. The selection of attributes improved model accuracy, and the best attribute selection was used by applying Wrapper method, while the best classification algorithms were the k-NN and Naive Bayes. According to the results, it was possible to classify the level of stress in pigs through their vocalization.

This study aimed to identify differences in swine vocalization pattern according to animal gender and different stress conditions. A total of 150 barrow males and 150 females (Dalland® genetic strain), aged 100 days, were used in the experiment. Pigs were exposed to different stressful situations: thirst (no access to water), hunger (no access to food), and thermal stress (THI exceeding 74). For the control treatment, animals were kept under a comfort situation (animals with full access to food and water, with environmental THI lower than 70). Acoustic signals were recorded every 30 minutes, totaling six samples for each stress situation. Afterwards, the audios were analyzed by Praat® 5.1.19 software, generating a sound spectrum. For determination of stress conditions, data were processed by WEKA® 3.5 software, using the decision tree algorithm C4.5, known as J48 in the software environment, considering cross-validation with samples of 10% (10-fold cross-validation). According to the Decision Tree, the acoustic most important attribute for the classification of stress conditions was sound Intensity (root node). It was not possible to identify, using the tested attributes, the animal gender by vocal register. A decision tree was generated for recognition of situations of swine hunger, thirst, and heat stress from records of sound intensity, Pitch frequency, and Formant 1.

Tuberculous involvement of the liver is usually a diffuse process, associated with miliary tuberculosis. However localized tuberculosis of the liver producing a macronodular tuberculoma or an abscess is rare. The authors present a case of pseudotumoral hepatic tuberculosis in a 34-year old woman. This patient presented a 2 month history of fever weight loss of 4Kg and right upper quadrant abdominal pain. She denied jaundice, choluria, or acholia. Laboratory investigation, including renal and liver function tests. revealed normal levels. Chest X-ray was normal. Abdominal ultrasonography demonstrated a hypoechoic nodule in the right hepatic lobe. CT scan showed hypodense areas in the same place and no retroperitoneal lymphadenopathy. Due to the inespecificity of the signs, symptoms and image findings, a diagnostic laparoscopy was performed, it was however inconclusive. Then, the patient was submitted to a laparotomy with ressection of the lesion. Histological examination revealed a tuberculoid granulomatous lesion with caseous necrosis. Postoperatively, the patient was placed on antituberculous chemotherapy with rifampin, isoniazid and pyrazinamide. Eight months later the patient is asymptomatic.

OBJECTIVE: To evaluate the importance of flexible bronchoscopy in tracheostomy patients in the process of decannulation to assess the incidence and types of laryngotracheal injury and compare the presence of such lesions with clinical criteria used for decannulation. METHODS: We studied 51 tracheostomized patients aged between 19 and 87 years, with tracheal stent for a mean of 46 ± 28 days and with clinical criteria for decannulation. They were submitted to tracheostomy tube occlusion tolerance testfor 24 hours, and then to flexible bronchoscopy. We described and classified the diagnosed laryngotracheal changes. We compared the clinical criteria for decannulation indication with the bronchoscopy-diagnosed laryngotracheal injuries that contraindicated decannulation. We identified the factors that could interfere in decannulation and evaluated the importance of bronchoscopy as part of the process. RESULTS: Forty (80.4%) patients had laryngotracheal alterations. Of the 40 patients considered clinically fit to decannulation, eight (20%) (p = 0.0007) presented with laryngotracheal injuries at bronchoscopy that contraindicated the procedure. The most frequent laryngeal alteration was vocal cords lesion, in 15 (29%) individuals, and granuloma, the most prevalent tracheal lesion, in 14 (27.5%) patients. CONCLUSION: flexible bronchoscopy showed a large number of laryngotracheal injuries, the most frequent being the vocal cords injury in the larynx and the granuloma in the trachea, which contributed to increase the decannulation procedure safety.

OBJETIVO: quantificar os valores do líquido amniótico no primeiro trimestre da gestação, em fetos normais, por meio de ultra-sonografia tridimensional e bidimensional. MÉTODOS: foram avaliados 25 fetos normais, da 8ª à 11ª semana de gestação. O estudo foi do tipo prospectivo longitudinal. As medidas do volume de líquido amniótico foram obtidas por meio de ultra-sonografia endovaginal, modos tridimensional e bidimensional. O estudo bidimensional consistiu em determinar o volume por cálculo matemático com base na forma de um elipsóide (constante 0,52), obtendo-se o volume do saco amniótico e do embrião. No estudo tridimensional, o volume do líquido amniótico foi feito pela técnica VOCAL, utilizando os graus de rotação 6, 9, 15 e 30°. Foi considerado como resultado final o volume do líquido amniótico obtido pelo grau de rotação6. Em ambos, o volume de líquido amniótico foi obtido pela subtração do volume do saco amniótico pela medida volumétrica do embrião. Para análise estatística utilizamos análise de variância (ANOVA), correlação e análise de regressão. O nível de significância adotado foi p < 0,05. RESULTADOS: a evolução no volume de líquido amniótico pela ultra-sonografia bidimensional foi de 5,4 para 39,5 cm³ da 8ª para a 11ª semana (ANOVA - p < 0,05). Observamos correlação entre idade gestacional e volume de líquido amniótico (p < 0,001, r² = 88,3%). No estudo tridimensional o volume de líquido amniótico aumentou de 5,7 para 42,9 cm³ da 8ª para a 11ª semana (ANOVA - p < 0,05). Também observamos correlação entre idade gestacional e volume de líquido amniótico (p < 0,001, r² = 98,1%). CONCLUSÃO: há aumento no volume de líquido amniótico no primeiro trimestre da gestação, quando avaliado nos modos bidimensional e tridimensional. Além disso, demonstramos que, quanto maior a idade gestacional, maior é o volume de líquido amniótico.

OBJETIVO: avaliar a evolução do volume do embrião (VE) entre a sétima e a décima semana de gestação por meio da ultra-sonografia tridimensional. MÉTODOS: realizou-se um estudo de corte transversal com 63 gestantes normais entre a sétima e a décima semana. Os exames ultra-sonográficos foram realizados por meio de um transdutor endocavitário volumétrico. Para o cálculo do VE, utilizou-se o método VOCAL (Virtual Organ Computer-aided Analysis) com ângulo de rotação de 12º, com delimitação de 15 planos seqüenciais. Para o VE foram calculadas médias, medianas, desvios padrão e valores máximo e mínimo em todas as idades gestacionais. Para se avaliar a correlação entre o VE e o comprimento cabeça-nádega (CCN) foi criado gráfico de dispersão, sendo o ajuste realizado pelo coeficiente de determinação (R²). Para se determinarem intervalos de referência do VE em função do CCN, utilizou-se a seguinte fórmula: percentil =VE+K versus dp, com K=1,96. RESULTADOS: o CCN variou de 9,0 a 39,7 mm, com média de 23,9 mm (±7,9 mm), enquanto o VE variou de 0,1 a 7,6 cm³, com média de 2,7 cm³ (±3,2 cm³). O VE foi altamente correlacionado com o CCN, sendo que o melhor ajuste foi obtido com regressão quadrática (VE=0,165 - 0,055 x CCN + 0,005 x CCN²; R²=0,853). O VE médio variou de 0,1 (-0,3 a 0,5 cm³) a 6,7 cm³ (3,8 a 9,7 cm³) no intervalo de 9 a 40 mm do CCN. Neste intervalo o VE aumentou 67 vezes, enquanto o CCN aumentou apenas 4,4 vezes. CONCLUSÕES: o VE é um parâmetro mais sensível que o CCN para avaliar o crescimento embrionário entre a sétima e a décima semana de gestação.

The vocal repertoire of some animal species has been considered a non-invasive tool to predict distress reactivity. In rats ultrasound emissions were reported as distress indicator. Capybaras[ vocal repertoire was reported recently and seems to have ultrasound calls, but this has not yet been confirmed. Thus, in order to check if a poor state of welfare was linked to ultrasound calls in the capybara vocal repertoire, the aim of this study was to track the presence of ultrasound emissions in 11 animals under three conditions: 1) unrestrained; 2) intermediately restrained, and 3) highly restrained. The ultrasound track identified frequencies in the range of 31.8±3.5 kHz in adults and 33.2±8.5 kHz in juveniles. These ultrasound frequencies occurred only when animals were highly restrained, physically restrained or injured during handling. We concluded that these calls with ultrasound components are related to pain and restraint because they did not occur when animals were free of restraint. Thus we suggest that this vocalization may be used as an additional tool to assess capybaras[ welfare.
