Franz Liszt’s Piano Sonata in B Minor: Precedents for an Analytical Evolution

Franz Liszt has all too often been discarded as the virtuosic showman, despite the fact that his several of works have often gained great praise and attracted scholarly engagement. However, one also finds striking development of formal design and tonal harmony in many of the works for his principal composition medium, the piano. This paper seeks to explore the practical application of James A. Hepokoski and Warren Darcy’s 'Sonata Theory' upon Liszt’s magnum opus for the instrument, the Sonata in B Minor.

I shall first consider the historical analyses placed upon the work that deal with structural design, as it pertains to the paradigm of Classical sonata-form. Previous research reveals two main theoretical camps; those in favour of a multi-movement analysis (with conflicting hypotheses therein) and those in favour of a single movement sonata-form. An understanding of these historical conceptions of the piece allows one to then highlight areas of conflict and offer a new solution.

Finally, I shall use Sonata Theory to survey the Sonata in B Minor’s landscape in a new light. The title ‘Sonata’ has clear generic implications, many of which are met by Liszt; 'Sonata Theory' provides a model with which to outline the compositional deformations employed by the composer and the implications of this practice. In particular, I offer new perspectives on the validity of the double-function form, insight into the rhetorical layout of a rotational discourse, and propose a nuanced analysis befitting of this striking work.

Superregular matrices and applications to convolutional codes

The main results of this paper are twofold: the first one is a matrix theoretical result. We say that a matrix is superregular if all of its minors that are not trivially zero are nonzero. Given a a×b, a ≥ b, superregular matrix over a field, we show that if all of its rows are nonzero then any linear combination of its columns, with nonzero coefficients, has at least a−b + 1 nonzero entries. Secondly, we make use of this result to construct convolutional codes that attain the maximum possible distance for some fixed parameters of the code, namely, the rate and the Forney indices. These results answer some open questions on distances and constructions of convolutional codes posted in the literature.

Síndrome de boca ardente

A Síndrome de Boca Ardente (SBA) é uma condição caracterizada por uma sensação descrita pelo paciente como ardência e que afeta a mucosa oral. Tem sido referida como dor orofacial crónica, sem lesões na mucosa oral ou outros sinais clínicos evidentes. Afeta predominantemente mulheres no período pós-menopáusico. A sua etiologia foi considerada multifatorial, contudo foram sugeridos como fatores etiológicos os seguintes fatores: locais, sistémico, psicológicos, neuropáticos e idiopático. O seu diagnóstico é complexo e essencialmente por exclusão. De forma a compreender quais são os fatores etiológicos implicados nesta síndrome, como é realizado o seu diagnóstico e quais são os tratamentos utilizados de forma eficaz, foi realizada uma revisão bibliográfica nas bases de dados “PubMed”e “B-On”. O tratamento geralmente tem como objetivo o alívio sintomático de forma a melhorar a qualidade de vida das pessoas afetadas por SBA, as modalidades de tratamento podem variar desde farmacológicos até aos não farmacológicos. Ainda não existe um consenso relativamente aos critérios de diagnósticos que devem ser utilizados e nem do mais eficaz. Há necessidade de realização de mais estudos de forma a criar algoritmos específicos para esta condição.

On the extension complexity of combinatorial polytopes

In this paper we extend recent results of Fiorini et al. on the extension complexity of the cut polytope and related polyhedra. We first describe a lifting argument to show exponential extension complexity for a number of NP-complete problems including subset-sum and three dimensional matching. We then obtain a relationship between the extension complexity of the cut polytope of a graph and that of its graph minors. Using this we are able to show exponential extension complexity for the cut polytope of a large number of graphs, including those used in quantum information and suspensions of cubic planar graphs.

A study of the electrical basis for the inhibition and excitation in autonomically innervated smooth muscle

The aim of this thesis was to investigate the electrical and mechanical responses to inhibitory non-adrenergic noncholinergic (NANC) nerve stimulation in the bovine retractor penis muscle (BRP) and compare them with those to an inhibitory extract made from this muscle. The extract may contain the NANC inhibitory transmitter of the BRP and possibly of other smooth muscles. Because of species differences in the electrical response to NANC nerves in the rat and rabbit anococcygeus the effects of the extract on these tissues was also investigated. Prior to the investigation of the extract, both the excitatory and inhibitory responses to field stimulation in the BRP, and the effects of passive membrane potential displacement were studied using conventional intra- or extracellular (sucrose gap) recording techniques. The majority of cells in the BRP were electrically quiescent independent of the resting tone. The most frequent (in approximately 25% of preparations) form of spontaneous activity, oscillations in membrane potential and tone, may represent a pacemaker activity. The BRP had cable properties; the time constant and space constant indicated a high membrane resistance. In the absence of tone, field stimulation of the BRP evoked excitatory junction potentials (ejps) in every cell impaled and contractions, graded with the strength, frequency and number of pulses; spikes were not observed. Guanethidine (1-3 x 10-5M) abolished the ejps and contractions, confirming their adrenergic origin. Noradrenaline added exogenously depolarised and contracted the muscle. These effects were blocked by the a-adrenoceptor antagonists, phentolamine and prazosin. However, phentolamine (2.5x 10-6M) inhibited the contraction without reducing the ejp significantly. These effects may be independent of adrenoceptor blockade or the ejp may be mediated by a substance other than noradrenaline (e.g. ATP) released from adrenergic nerves. Prazosin (1.4 x lO-6M) failed to block either the ejp or contraction, indicating the possible existence of two types of adrenoceptor in the BRP; one activated by neuronally-released and the other by exogenously-added noradrenaline. ATP, a contaminant in the extract, also depolarised and contracted the BRP. Physostigmine reduced whilst atropine enhanced the ejps and contractions without similarly affecting the response to exogenous noradrenaline. This confirmed the presence of a cholinergic inhibitory innervation acting on the excitatory adrenergic fibres (Klinge and Sjostrand, 1977). TEA (1 x lO-4M) enhanced the ejp and contraction. Higher concentrations (0.5 to 10 x 10-3M) depolarised, increased the tone and evoked electrical and mechanical oscillations but no spikes. The depolarisation and contraction to exogenous noradrenaline were not enhanced, indicating that TEA acts on the adrenergic nerves. Some post-synaptic effect to block K+ channels also seems likely. The relationship between ejp amplitude and membrane potential in the double sucrose gap was linear and indicated a reversal potential more positive than -30mV. Electrotonic pulse amplitude decreased during the ejp, indicating an increased membrane conductance. Ejps and contractions were reduced following the replacement of the NaCl of the Krebs solution with sodium glutamate. This may be due to the effects of glutamate itself (e.g. Ca2+ chelation) rather than reduction in the membrane Cl- gradient. Tone usually developed spontaneously and was accompanied by membrane depolarisation (from -53 to -45mV) which may open voltage-dependent channels, causing Ca2+ entry and/or its release from intracellular binding sites. Field stimulation produced inhibitory potentials (ijps) and relaxations graded with the strength and number of pulses but showing little frequency dependence. Rebound depolarisation and contraction often followed the ijp and relaxation. Tetrodotoxin (3 x IO-6M), but not adrenergic or cholinergic antagonists, abolished the ijp and relaxation, confirming their non-adrenergic non-cholinergic neurogenic nature. The extract, prepared and acid-activated as described by Gillespie, Hunter and Martin (1981), hyperpolarised and relaxed the BRP, as did sodium nitroprusside and adenosine triphosphate (ATP). Unlike the activated extract or sodium nitroprusside, desensitisation to ATP occurred rapidly and without any change in the inhibitory electrical or mechanical responses to field stimulation. The ijp and relaxation in the BRP were insensitive to apamin but abolished by oxyhaemoglobin (4-8 x 10-6M), as were the responses to extract and sodium nitroprusside. In TEA (10-2M), field stimulation evoked relaxations with no accompanying electrical change. The ijp may be unconnected with or additional to another mechanism producing relaxation. The relationship between membrane potential and ijp in the BRP was non-linear. Ijp amplitude was initially increased during membrane potential displacement from -45mV to approximately -60mV. Thereafter (-60 to -l03mV) the ijp was reduced. Ijps were abolished at -27 and -103mV; reversal was not observed. The hyperpolarisation to extract was also enhanced during passive displacement of the membrane potential to more negative values (-57mV). Membrane resistance increased during the ijp. The extract produced inconsistent changes in membrane resistance, possibly because of the presence of more than one active component. K+ withdrawal failed to enhance the ijp or hyperpolarisation to extract and 20mM K+ did not abolish the the ijp at membrane potentials exceeding EK (-49mV). Thus, the ijp or hyperpolarisation to extract are unlikely to be mediated by an increased K+ conductance. Reducing the Cl- abolished the hyperpolarisation to field stimulation and extract. This occurred more quickly than the anticipated reduction in the Cl- gradient and may be due to Ca2+ chelation by the anion substitute (glutamate or benzenesulphonate) or blockade of the resting conductance which is normally inactivated by the transmitter. Ouabain (1-5x 10-5M), which reduces both the Na+ and Cl- gradients, abolished the ijp, implicating either of these ions as the ionic species involved. In the rat and rabbit anococcygeus, field stimulation and extract each reduced guanethidine-induced tone. This was unaccompanied in the majority of cells in the rat by any significant electrical response. In the remaining cells, inhibition of the membrane potential oscillations occurred. The rabbit anococcygeus differed in that inhibition of the electrical oscillations was observed in every cell exhibiting this behaviour. However, the majority of cells in the rabbit were electrically quiescent and showed only small hyperpolarisations to field stimulation and no electrical response to extract. Apamin (1 x 10-7M) failed to block the electrical and mechanical response to field stimulation in the rabbit but did inhibit transiently that to extract. The latter effect may be due to the initial excitatory effects of apamin. The similarities between the electrical effects of the extract and those of inhibitory nerve stimulation in the BRP, rat and rabbit anococcygeus muscles are generally consistent with their being mediated by the same active component. Moreover, the ijp in the BRP shows properties which have not been reported in other non-adrenergic noncholinergically innervated smooth muscles.

Validity and reliability of the Cyber-aggression Questionnaire for Adolescents (CYBA)

Cybercrime is a growing and worrisome problem, particularly when it involves minors. Cyber-aggression among adolescents in particular can result in negative legal and psychological consequences for people involved. Therefore, it is important to have instruments to detect these incidents early and understand the problem to propose effective measures for prevention and treatment. This paper aims to design a new self-report, the Cyber-Aggression Questionnaire for Adolescents (CYBA), to evaluate the extent to which the respondent conducts aggressions through a mobile phone or the internet and analyse the factorial and criterion validity and reliability of their scores in a sample of adolescents from Asturias, Spain. The CYBA was administered to 3,148 youth aged between 12 and 18 years old along with three self-reports to measure aggression at school, impulsivity, and empathy. Regarding factorial validity, the model that best represents the structure of the CYBA consists of three factors (Impersonation, Visual-sexual Cyber-aggression, and Verbal Cyber-aggression and Exclusion) and four additional indicators of Visual Cyber-aggression-Teasing/Happy Slapping. Regarding criterion validity, the score on the CYBA correlates positively with aggression at school and impulsivity and negatively with empathy. That is the way cyber-aggression correlates with these three variables, according to previous empirical evidence. The reliability of the scores on each item and factor of the CYBA are adequate. Therefore, the CYBA offers a valid and reliable measure of cyber-aggression in adolescents.

Articulação saúde-escola: a intervenção em contexto comunitário

As perturbações psiquiátricas e os problemas de saúde mental infantojuvenil têm vindo a merecer especial atenção por parte da comunidade científica, não só pelo facto de se estimar que 10 a 20% das crianças apresentem um ou mais problemas de saúde mental, não só por estes valores terem tendência a aumentar, mas também pelo impacto humano e financeiro que acarretam para a sociedade. Em Portugal, o Plano Nacional da Saúde Mental 2007-2016 é categórico ao afirmar a necessidade de promover a saúde mental infantojuvenil junto da população e ao salientar a importância do envolvimento e articulação com outras estruturas comunitárias ligadas à saúde, educação e direito de menores. Este trabalho vai de encontro a estas linhas de orientação, na medida em que procura identificar, desenvolver e implementar diversos aspetos inerentes à vertente comunitária da saúde mental infantojuvenil. Numa primeira fase é realizado um levantamento das reais necessidades da população infantojuvenil do concelho de Odemira e é definida uma rede de articulação entre os serviços de saúde, escolas e outras entidades locais com competência nesta área. De forma a melhorar a prestação dos cuidados e a garantir respostas adequadas às necessidades identificadas, também se procurou o individual desenvolvimento de competências especializadas na área da saúde mental infantojuvenil. Por último, atendendo à importância da implementação atempada de medidas preventivas de determinados fenómenos psicopatológicos, procurou-se treinar e desenvolver a capacidade de sensibilização e reforço de competências de uma bolsa populacional específica: a comunidade escolar. De um modo geral, os resultados obtidos demonstram aplicabilidade na prática clínica dos cuidados, contribuindo para a melhoria dos mesmos. Algumas das estratégias utilizadas constituem-se como ponto de partida para projetos futuros, podendo ser replicadas e adequadas a outros contextos de intervenção; ABSTRACT: LINK HEALTH-SCHOOL: the intervention in the community context Psychiatric disorders and problems of youth mental health have been given special attention by the scientific community, not only because it is estimated that 10-20% of children present one or more mental health problems, not only because these values have tendency to increase, but also the human and financial impact to society. In Portugal, the Mental Health National Plan 2007-2016 is emphatic in affirming the need to promote the mental youth health within the population and to emphasize the importance of the involvement and coordination with other community entities related to health, education and minors rights. This paper follows these guidelines, it tries to identify, develop and implement various aspects related to the Community part of youth health. In the first phase is carried out a survey of the real needs of youth population of the Odemira County and defined a network between health services, schools and other local organizations with expertise in this area. In order to improve the delivery of health care and ensure appropriate responses to the identified needs, also sought the individual development of expertise in the area of youth mental health. Finally, given the value of timely implementation of preventive measures of certain psychopathological phenomena, it sought to train and develop the awareness and skills improvement of a specific population: the school community. In general, the results prove the applicability of the procedures in clinical practice, contributing to a practice improvement. Some of the strategies used are the Foundation for future projects, they can be replicated and adapted to other contexts of intervention.

Las medidas de acogimiento y su influencia en los menores desprotegidos

[ES]En el presente trabajo se realiza un recorrido teórico de la familia, de los deberes y obligaciones que les corresponden a los padres para con sus hijos, además de estudiarse cómo el cese o la mala práctica de esos compromisos pueden incidir negativamente en ellos. Exponiéndose los diferentes tipos de maltrato infantil, se explican las medidas de acogimiento que se adoptan cuando la situación familiar es considerada perjudicial o peligrosa para el menor. Para ello, mediante entrevistas a distintos profesionales y técnicos de la Sección de Protección a la Infancia de la provincia de Bizkaia, se da a conocer la situación actual de los centros y hogares de acogimiento, la visión profesional acerca de la problemática presentada, los planes creados para el acogimiento familiar, y cómo es el proceso de captación de familias de acogida. Así mismo, se recoge el testimonio de una persona acogida en la infancia.

Análisis de la respuesta educativa desde la escuela a los menores en acogimiento residencial: un estudio de caso en la Comunidad de Madrid

The reality of children living in foster homes is clearly linked to the professionals that surround them both in the educational and residentialsphere. These are children who in all aspects of their livesat all hours, are exposed to the professionalism of those who work with them and not the affection of a family; their development is fully mediated by institutions. It is therefore a priority that teachers have specific training on children living infoster care, that general government (Education and Social Services) provide guidelines for action agreed to allow the coordination between the different professionals involved with children in foster care, considering the complexity of this coordination, as there are many institutions involved with these children: Social Services, schools, foster residences foster ... among others. Educational professionals have an important role in this intervention process, being their good professional work the one that favors a tight development of children in the educational field, but this intervention takes place generally from the ignorance of the specific situation faced by children living inresidential care and from the failure of the educational administration into sharing protocols, time and space, necessary for a proper coordination. In the event children incustody, and because of the uniqueness of their situation and the importance of a good intervention, there should be no space for improvisation.In addition intervention with children in residential care has to be based on a training and intervention from the complementary roles that is to be structured, systematic and evaluated in a continuously way by the professionals involved.We understand that the principle of equality in education requires to offer these minors an opportunity based on an appropriate intervention with formed professionals, knowledgeable and with the time and the necessary conditions...

Perceção da terminologia legal e dos procedimentos judiciais por menores em conflito com a lei

Todos os seres humanos, independentemente da sua fase no ciclo vital ou qualquer tipo de condição, são seres plenos de direitos e merecem ser tratados com dignidade e respeito. Os jovens, por se encontrarem numa etapa inicial do desenvolvimento humano, requerem atenção e assistência especiais. A presença de crianças e jovens envolvidos no sistema de justiça é cada vez mais frequente e devido à sua idade precoce, inúmeras leis e documentos foram desenvolvidos para proteger os menores, com o objetivo de fornecer uma justiça adaptada à sua maturidade cognitiva e emocional em todas as fases do processo judicial (antes, durante e após). Quando estas questões são referentes a jovens na qualidade de ofensores, tomam particular pertinência, devido à possibilidade do seu direito de defesa ficar comprometido. Uma vez que, em Portugal, a literatura existente acerca de como o sistema de justiça interage com os jovens em conflito com a Lei é escassa, o presente estudo é revestido de particular pertinência. Assim, esta investigação visa apresentar um estudo quantitativo que pretende compreender a perceção que os jovens em conflito com a Lei têm da terminologia legal e dos procedimentos judiciais. A recolha de dados realizou-se baseada no método de inquérito suportado pela técnica de questionário fechado. Elaborou-se um instrumento constituído por 69 questões dicotómicas, com um tempo de realização estimado de 15 minutos. Para a realização da investigação foram obtidas as autorizações necessárias (i.e. Comissão de Ética da Universidade Fernando Pessoa e Direção Geral de Reinserção e Serviços Prisionais) e os respetivos consentimentos informados dos participantes. Os resultados revelam que, em geral, os jovens inquiridos têm um relativo bom conhecimento da terminologia legal e dos procedimentos judiciais que ocorreram durante o processo tutelar de que foram alvo. Verificou-se uma diferença de conhecimento/experiência significativa entre os Centros Educativos do Porto e da Guarda, sendo que os jovens do Porto revelarem maiores conhecimentos que os jovens da Guarda. Apesar dos jovens apresentarem conhecimento acerca do sistema, existem determinadas lacunas às quais se deve atentar. Assim, depreende-se que o sistema jurídico português possa estar a empenhar-se de forma a cumprir as normas e legislações nacionais e internacionais e garantir o bem-estar e esclarecimento do jovem em conflito com a lei. Contudo, reconhece-se que é da responsabilidade dos intervenientes judiciais com contacto direto com a criança (e.g. advogado, juiz) esta função, pelo que os lapsos identificados devem ser colmatados de forma a garantir que o jovem seja (como é) um cidadão pleno de direitos e dignidade quando contacta com o sistema jurídico.

Alternativas ao internamento juvenil através da colaboração de família madrinha

As intervenções alternativas são medidas que não devem ser rechaçadas por nenhum governante. O sistema de encarceramento penal existente no Brasil, assim como em muitas nações mundo afora, vem mostrando há décadas, ser um sistema falido, vez que é impossível (res)socializar alguém em cadeias que são verdadeiras masmorras. Não há condições de melhoramento, nem na esfera física ou psíquica deste sistema nefasto, que só funciona para pegar pobres, pretos, analfabetos e moradores das periferias. Dentro dos maiores problemas apontados por pesquisas atuais, a superlotação, a violência, o tráfico de drogas, o abuso sexual e a falta de uma ocupação que garanta a (res)socialização, forma verdadeiras faculdades do crime, onde o preso ou o adolescente chega como estagiário e sai como mestre na arte da criminalidade delinquente. Esta pesquisa em Criminologia e direito comparado, com foco no Brasil (Recife) e na Alemanha (Freiburg), faz uma contextualização histórica do tema, de forma geral e mais focada nos países comparados. Após esta contextualização, o trabalho retrata e analisa a situação dos jovens em conflito com a Lei, e explana as intervenções alternativas à internação, aconselhando a solução do acolhimento por famílias madrinhas.

La migración infantil indocumentada de Centroamérica, un desafío a la reformulación de la política migratoria de Estados Unidos. Estudio de caso de Honduras (2010-2014)

El siguiente estudio de caso analiza la influencia de la llegada de la migración infantil indocumentada centroamericana en la reformulación de la política migratoria de Estados Unidos en el período 2010-2014. Enfocándose en el caso de Honduras para dar a conocer y analizar las causas que crean las dinámicas migratorias por parte de los menores, este trabajo analiza como la llegada de estas poblaciones genera ciertos efectos en el proceso de toma de decisión de las políticas internas de los Estados Unidos. Por un lado, para resaltar las características del fenómeno migratorio, se utilizan las teorías de redes sociales y la teoría push and pull. Por otro, mediante los conceptos de Sensibilidad y Vulnerabilidad expuestos en la teoría de la Interdependencia Compleja de las Relaciones Internacionales, como también el concepto de Seguridad Societal propuesto por Barry Buzan se estudia el nivel de influencia del fenómeno infantil en el gobierno norteamericano.

Antecedente nacional e internacional sobre la percepción y los derechos de las niñas, los niños, los y las adolescentes

Until the middle of the XVIII Century, children were considered as miniature adults, but with Jean Jacob Rousseau the study of the development of the human being was started and the foundation was set up for the new science of Paidology (the study of children), wich focuses on the different intellectual and physical conflicts which children face, and also for other sciencies such as Paidofilaxis, Pueroculture and Pediatrics. The Society of Nations, created, in 1919, the Consultancy for the Trafficking of Women and the Protection of Children, and in Geneva, the International Union for Aid was founded in 1920. In Argentina, the First American Congress for Children was organized in 1916, and others followed. The first Declaration of Childrens Right was proclaimed in 1924 and then followed the first Ten Commandments of Childrens Rights. In Costa Rica in 1929, a project was presented for the Constitutional Congress to establish an institution for the protection of children, wich was duly enacted into law in 1930 with the name of National Institution for the Protection of Children (Patronato Nacional de la Infancia, PANI) whose duty was to oversee the welfare of minors and their physical, intellectual, moral and emotional development. In 1930, the first Declaration of the Rights for Costarrican Children was proclaimed. The creation of the PANI, the declaration of Childrens Rights, and the enactment of a Code for Infants (1932), constitute the three events that signal Costa Rica as one of the pioneers countries in Latin American and the World, in the protectionof children and mothers. At the end of the article, some of the crucial events that have happened during the decades that PANI has been working in the country are analized.
