(Des)obediències de la reducció vocàlica en el català de Mallorca

En el català de Mallorca, el procés de reducció vocàlica de les vocals mitjanes de la sèrie anterior a e neutra en posició àtona no opera (o subaplica) en determinades circumstàncies: (a) en formes derivades productives amb una vocal àtona situada a la síl·laba esquerra o inicial del radical i alternant amb e tancada o e oberta en el radical de la forma primitiva; (b) en formes verbals amb una vocal àtona situada a la síl·laba esquerra o inicial del radical i alternant amb e tancada en una altra forma verbal del mateix paradigma flexiu; (c) en manlleus i paraules apreses amb una vocal àtona e situada, també, a la síl·laba esquerra o inicial del radical i generalment precedida d"una consonant labial. En aquest treball, argumentem que hi ha dos factors que conspiren perquè això sigui d"aquesta manera: (a) tal com ja s"ha fet notar en treballs anteriors, la voluntat d"aquestes vocals d"assemblar-se a les vocals corresponents que apareixen en mots del mateix paradigma derivatiu o flexiu, i, en el cas de la derivació, sobretot quan la relació derivativa és productiva; (b) l"estatus privilegiat de la síl·laba situada a l"esquerra o a l"inici del radical. Per donar compte del primer factor, proposem una nova interpretació dels fets emmarcada en la Teoria de la Correspondència Transderivacional i el model dels Paradigmes Òptims. Per donar compte del segon factor, que ha passat desapercebut en aproximacions anteriors a les mateixes dades, partim de la Teoria de la Fidelitat Posicional i de la Teoria del Marcatge Posicional.

Building legitimacy by criticising the pharmaceutical industry: a qualitative study among prescribers and local opinion leaders.

PRINCIPLES: The literature has described opinion leaders not only as marketing tools of the pharmaceutical industry, but also as educators promoting good clinical practice. This qualitative study addresses the distinction between the opinion-leader-as-marketing-tool and the opinion-leader-as-educator, as it is revealed in the discourses of physicians and experts, focusing on the prescription of antidepressants. We explore the relational dynamic between physicians, opinion leaders and the pharmaceutical industry in an area of French-speaking Switzerland. METHODS: Qualitative content analysis of 24 semistructured interviews with physicians and local experts in psychopharmacology, complemented by direct observation of educational events led by the experts, which were all sponsored by various pharmaceutical companies. RESULTS: Both physicians and experts were critical of the pharmaceutical industry and its use of opinion leaders. Local experts, in contrast, were perceived by the physicians as critical of the industry and, therefore, as a legitimate source of information. Local experts did not consider themselves opinion leaders and argued that they remained intellectually independent from the industry. Field observations confirmed that local experts criticised the industry at continuing medical education events. CONCLUSIONS: Local experts were vocal critics of the industry, which nevertheless sponsor their continuing education. This critical attitude enhanced their credibility in the eyes of the prescribing physicians. We discuss how the experts, despite their critical attitude, might still be beneficial to the industry's interests.

Aplicações da ultra-sonografia tridimensional na avaliação do cerebelo fetal

Nos últimos anos a ultra-sonografia tridimensional tem-se tornado um método de imagem de grande importância no diagnóstico em obstetrícia. Um de seus benefícios seria a maior sensibilidade, em relação ao ultra-som bidimensional, no diagnóstico de algumas malformações fetais. As potenciais aplicações desse novo método seriam uma maior acurácia na medida do volume de órgãos fetais, a possibilidade de rever volumes na ausência da paciente, a possibilidade de utilizar diferentes planos para avaliar determinada estrutura anatômica e a capacidade de transmissão de volumes para centros de referência. A avaliação ultra-sonográfica do cerebelo fetal é de extrema importância, pois, comprovadamente, alterações no seu desenvolvimento estão correlacionadas com alterações do crescimento fetal e anomalias congênitas. O objetivo desta atualização é demonstrar os métodos VOCAL™ e 3D XI™ na avaliação do cerebelo fetal, seus potenciais benefícios e o que há de mais atual na literatura a respeito deste assunto.

Avaliação por imagem da paralisia de pregas vocais

Paralisia das pregas vocais é causa frequente de rouquidão, podendo ser secundária a várias lesões ao longo do trajeto do X par craniano e seus ramos, particularmente os nervos laríngeos recorrentes. Apesar de grande parte dos casos ser idiopática, os métodos de imagem são muito importantes na pesquisa de fatores etiológicos, tais como lesões neoplásicas da tireoide e esôfago com invasão secundária dos nervos laríngeos recorrentes. Além destas, outras anormalidades como aneurismas do arco aórtico e da artéria subclávia direita podem ser encontradas. É fundamental que o radiologista conheça a anatomia pertinente a esta região e as principais afecções que podem ocorrer, para que o estudo seja corretamente planejado, auxiliando o diagnóstico e o planejamento terapêutico. Além disso, como até 35% dos casos de paralisia da prega vocal são assintomáticos, o conhecimento dos sinais radiológicos que indicam esta condição é indispensável, cabendo ao radiologista alertar o médico assistente sobre os achados do exame. Neste trabalho realizamos uma revisão da anatomia e das principais doenças responsáveis pela paralisia de cordas vocais, demonstrando-as por meio de estudos de tomografia computadorizada e ressonância magnética de casos típicos. Mostramos, também, as alterações radiológicas próprias da laringe que indicam a presença de paralisia das pregas vocais.

Reprodutibilidade interobservador dos índices vasculares do Doppler de amplitude tridimensional do embrião entre 7 e 10 semanas e 6 dias de gestação

OBJETIVO: Avaliar a reprodutibilidade interobservador dos índices de vascularização do Doppler de amplitude tridimensional (Doppler de amplitude 3D) no primeiro trimestre de gestação. MATERIAIS E MÉTODOS: Realizou-se estudo de reprodutibilidade com 32 gestantes normais entre 7 e 10 semanas e 6 dias. Para o cálculo do volume tridimensional dos embriões utilizou-se o método VOCAL (Virtual Organ Computer-aided AnaLysis) com ângulo de rotação de 12°. Em seguida obtiveram-se, automaticamente, os três índices vasculares do Doppler de amplitude 3D: índice de vascularização (VI), índice de fluxo (FI) e índice de vascularização e fluxo (VFI). Para o cálculo da variabilidade interobservador, um examinador realizou uma segunda medida dos 32 embriões e um segundo examinador realizou uma terceira medida dos mesmos volumes, ambos desconhecendo os resultados do outro. Utilizaram-se, para análise estatística, o coeficiente de correlação intraclasse (CCI) e gráficos de Bland-Altman. RESULTADOS: Observou-se boa reprodutibilidade interobservador dos três índices vasculares. O VI apresentou CCI = 0,9 e média da diferença = -1,1; o FI apresentou CCI = 0,9 e média da diferença = -0,5; e o VFI apresentou CCI = 0,9 e média da diferença = -1,1. CONCLUSÃO: Os índices vasculares do Doppler de amplitude 3D do embrião no primeiro trimestre de gestação foram altamente reprodutíveis, em especial o FI.

Ortner’s syndrome: a case report and literature review

AbstractThe authors report the case of a 55-year-old female, hypertensive, smoker patient presenting with dysphonia, dysphagia and persistent dry cough. Laryngoscopy diagnosed left vocal cord paralysis. Computed tomography demonstrated saccular aneurysm of the inferior wall of the aortic arch, stretching the left recurrent laryngeal nerve, a finding compatible with Ortner’s syndrome.

I serà a partir d'aquests exemples, que he fet els meus propis arranjaments per a viola de gamba i que incloc en aquest treball.

Énfasis en los eslóganes publicitarios de radio y televisión

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.

A Markov chain analysis of emotional exchange in voice-to-voice communication: Testing for the mimicry hypothesis of emotional contagion

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.

Osteolytic metastasis detected in a patient with lung carcinoma by F18-FDG PET

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.

El canto coral y las orquestas infantiles, una educación en valores = Choir singing and children’s orchestras, an education in values

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

Modificação enzimática da farinha de arroz visando a produção de amido resistente

The aim of this work was to study the enzymatic modification on rice flour using lipase pancreatic and amyloglucosidase to obtain resistant starch. For this, Response Surface Methodology (RSM) was used to determine the best operating conditions for each enzyme. For lypase pancreatic, the highest value for resistant starch (45%) was achieved within 2 h reaction at pH 7 using an enzyme/substrate ratio of 4% (w/w) and Dp= 100/200 tyler. For amyloglucosidase, optima conditions corresponded to an enzyme/substrate ratio of 0,006 mL/g and Dp= 100/200 tyler at 45 ºC, yielding 57% of resistant starch in 2 h reaction. These results show the potential of using both enzymes to modified rice flour, increasing the resistant starch in about 5.7 folds in relation to the flour without treatment (resistant starch=10.6%).

The Sottunga-Jurmo shear zone : structure and deformation history of a crustal-scale ductile shear zone in SW Finland

The aim of this study is to gain a better understanding of the structure and the deformation history of a NW-SE trending regional, crustal-scale shear structure in the Åland archipelago, SW Finland, called the Sottunga-Jurmo shear zone (SJSZ). Approaches involving e.g. structural geology, geochronology, geochemistry and metamorphic petrology were utilised in order to reconstruct the overall deformation history of the study area. The study therefore describes several features of the shear zone including structures, kinematics and lithologies within the study area, the ages of the different deformation phases (ductile to brittle) within the shear zone, as well as some geothermobarometric results. The results indicate that the SJSZ outlines a major crustal discontinuity between the extensively migmatized rocks NE of the shear zone and the unmigmatised, amphibolite facies rocks SW of the zone. The main SJSZ shows overall dextral lateral kinematics with a SW-side up vertical component and deformation partitioning into pure shear and simple shear dominated deformation styles that was intensified toward later stages of the deformation history. The deformation partitioning resulted in complex folding and refolding against the SW margin of the SJSZ, including conical and sheath folds, and in a formation of several minor strike-slip shear zones both parallel and conjugate to the main SJSZ in order to accommodate the regional transpressive stresses. Different deformation phases within the study area were dated by SIMS (zircon U-Pb), ID-TIMS (titanite U-Pb) and 40Ar/39Ar (pseudotachylyte wholerock) methods. The first deformation phase within the ca. 1.88 Ga rocks of the study area is dated at ca. 1.85 Ga, and the shear zone was reactivated twice within the ductile regime (at ca. 1.83 Ga and 1.79 Ga), during which the strain was successively increasingly partitioned into the main SJSZ and the minor shear zones. The age determinations suggest that the orogenic processes within the study area did not occur in a temporal continuum; instead, the metamorphic zircon rims and titanites show distinct, 10-20 Ma long breaks in deformation between phases of active deformation. The results of this study further imply slow cooling of the rocks through 600-700ºC so that at 1.79 Ga, 2 the temperature was still at least 600ºC. The highest recorded metamorphic pressures are 6.4-7.1 kbar. At the late stages or soon after the last ductile phase (ca. 1.79 Ga), relatively high-T mylonites and ultramylonites were formed, witnessing extreme deformation partitioning and high strain rates. After the rocks reached lower amphibolite facies to amphibolite-greenschist facies transitional conditions (ca. 500-550ºC), they cooled rapidly, probably due to crustal uplift and exhumation. The shear zone was reactivated at least once within the semi-brittle to brittle regime between ca. 1.79 Ga and 1.58 Ga, as evidenced by cataclasites and pseudotachylytes. In summary, the results of this study suggest that the Sottunga-Jurmo shear zone (and the South Finland shear zone) defines a major crustal discontinuity, and played a central role in accommodating the regional stresses during and after the Svecofennian orogeny.

Resa i röstens landskap : en narrativ studie av hur lärare blir professionella röstanvändare

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.
