Effect of gaze direction on neck muscle activity during cervical rotation

Control of the neck muscles is coordinated with the sensory organs of vision, hearing and balance. For instance, activity of splenius capitis (SC) is modified with gaze shift. This interaction between eye movement and neck muscle activity is likely to influence the control of neck movement. The aim of this study was to investigate the effect of eye position on neck muscle activity during cervical rotation. In eleven subjects we recorded electromyographic activity (EMG) of muscles that rotate the neck to the right [right obliquus capitis inferior (OI), multifides (MF), and SC, and left sternocleidomastoid (SCM)] with intramuscular or surface electrodes. In sitting, subjects rotated the neck in each direction to specific points in range that were held statically with gaze either fixed to a guide (at three different positions) that moved with the head to maintain a constant intra-orbit eye position or to a panel in front of the subject. Although right SC and left SCM EMG increased with rotation to the right, contrary to anatomical texts, OI EMG increased with both directions and MF EMG did not change from the activity recorded at rest. During neck rotation SCM and MF EMG was less when the eyes were maintained with a constant intra-orbit position that was opposite to the direction of rotation compared to trials in which the eyes were maintained in the same direction as the head movement. The inter-relationship between eye position and neck muscle activity may affect the control of neck posture and movement.

Management of plant invasions mediated by frugivore interactions

1. Some of the most damaging invasive plants are dispersed by frugivores and this is an area of emerging importance in weed management. It highlights the need for practical information on how frugivores affect weed population dynamics and spread, how frugivore populations are affected by weeds and what management recommendations are available. 2. Fruit traits influence frugivore choice. Fruit size, the presence of an inedible peel, defensive chemistry, crop size and phenology may all be useful traits for consideration in screening and eradication programmes. By considering the effect of these traits on the probability, quality and quantity of seed dispersal, it may be possible to rank invasive species by their desirability to frugivores. Fruit traits can also be manipulated with biocontrol agents. 3. Functional groups of frugivores can be assembled according to broad species groupings, and further refined according to size, gape size, pre- and post-ingestion processing techniques and movement patterns, to predict dispersal and establishment patterns for plant introductions. 4. Landscape fragmentation can increase frugivore dispersal of invasives, as many invasive plants and dispersers readily use disturbed matrix environments and fragment edges. Dispersal to particular landscape features, such as perches and edges, can be manipulated to function as seed sinks if control measures are concentrated in these areas. 5.Where invasive plants comprise part of the diet of native frugivores, there may be a conservation conflict between control of the invasive and maintaining populations of the native frugivore, especially where other threats such as habitat destruction have reduced populations of native fruit species. 6. Synthesis and applications. Development of functional groups of frugivore-dispersed invasive plants and dispersers will enable us to develop predictions for novel dispersal interactions at both population and community scales. Increasingly sophisticated mechanistic seed dispersal models combined with spatially explicit simulations show much promise for providing weed managers with the information they need to develop strategies for surveying, eradicating and managing plant invasions. Possible conservation conflicts mean that understanding the nature of the invasive plant-frugivore interaction is essential for determining appropriate management.

Art after 9/11

This article examines ways in which art can help broaden understandings of contemporary security challenges, especially in view of the limits of conventional forms of strategic and policy analysis. The article focuses especially on responses to 9/11 in literature, the visual arts, architecture, and music, and considers some epistemological questions about the status of art as a way of knowing political events, like those of 9/11, that escape state-based forms of security analysis.

A retrospective lyrical analysis of songs written by adolescents with anorexia nervosa

Song-writing plays a central role in music therapy with adolescents. A retrospective lyrical analysis of songs written by adolescents with anorexia nervosa was undertaken in order to identify common themes solicited through song-writing interventions. Fifteen participants contributed 17 songs, from which 368 lyrical units were identified. A modified content analysis approach was used with each lyrical unit being categorised to one of six themes determined from the literature and clinical experience. The theme of 'identity' was used most frequently (28%), with the sub-theme of 'exploring new behaviours, positive self-talk' being addressed most often (12.5% of total). The dominance of the developmentally important theme of 'identity' may reflect the relationship between adolescents, music and identity or may be related to the way in which anorexia nervosa has been theorised to assist the adolescent in managing challenges to the emerging sense of self.

A SAGA DO HEROI E O ESVAZIAMENTO DE CRISTO: ANÁLISE DE FILIPENSES 2,5-11

A partir do texto de Filipenses 2,5-11 este trabalho realiza uma exegese no texto conhecido como kenosis. Para isso, busca a identificação de traços existentes na herança ideológica da sociedade da época da redação deste documento para, em seguida, apontar para as possibilidades de estruturas míticas recorrentes. Faz uma primeira análise no mundo cultural, social e religioso do apóstolo Paulo e passa por uma breve abordagem da história da pesquisa. Oferece uma possibilidade de tradução do texto grego para o português e depois, quer visualizar em forma gráfica a estrutura e o movimento do hino cristológico . Apresenta o monomito e a análise do discurso como ferramentas metodológicas para a produção de duas novas leituras. Com o uso dessas metodologias, procura mostrar as semelhanças entre certas estruturas míticas recorrentes e o esvaziamento de Cristo na tradição paulina. Busca validar a proposta apresentando outras narrativas míticas que impregnavam a imagética da sociedade greco-romana. Ao final sugere alguns passos para uma leitura da kenosis como crítica social.

CANTO, ENCANTO E DESENCANTO: um estudo da tensão entre a prática do Canto Coral frente às novas tendências musicais nas Igrejas Batistas na cidade de Campinas.

Nesta pesquisa desenvolvemos um estudo focado na convivência conflituosa entre a música tradicional e a música contemporânea. Foi desenvolvida em um grupo religioso protestante específico, intuindo investigar a hipótese de que há uma tensão entre a prática do Canto Coral e as novas tendências musicais representadas pelas Bandas. Como procedimento metodológico utilizamos uma pesquisa de campo que avaliou a realidade musical em algumas Igrejas Batistas de Campinas. A partir dos resultados obtidos sugerimos ações concretas à práxis pastoral. O primeiro capítulo propõe uma retrospectiva conceitual e histórica do Canto Coral, avaliando sua função antes e depois do processo da reforma e da nova mentalidade musical desenvolvida por Lutero. O segundo capítulo mostra o desenvolvimento da pesquisa realizada junto a seis Igrejas Batistas. Tenta mensurar o gosto musical dos membros dessas comunidades através de um estudo comparativo a partir dos dois pólos: Canto Coral e Banda, ambos, sendo o específico de um campo maior: Tradição e Contemporâneo. O terceiro capítulo, partindo dos impulsos obtidos, desenvolve uma visão crítica sobre os aspectos da tradição, da aceitação à novas tendências, e da tensão propriamente desenvolvida na convivência entre estilos musicais distintos. Mediante tal realidade conflituosa, apresentamos um desafio à práxis pastoral no sentido de se obter possibilidades para uma convivência musical pacífica, considerando a inserção de elementos da contemporaneidade e da tradição na liturgia Batista.

AS FEIAS (E OS FEIOS) QUE ME DESCULPEM, MAS BELEZA É FUNDAMENTAL : O USO CONTEMPORÂNEO DA IMAGEM E SUA INFLUÊNCIA NA MUDANÇA DOS PARADIGMAS ESTÉTICOS UTILIZADOS NA MÚSICA GOSPEL NO BRASIL

Este trabalho analisa sociologicamente na contemporaneidade o campo imagético na música gospel e de que forma, este influencia na mudança dos paradigmas imagético - estéticos utilizados pelas produtoras fonográficas em seu marketing religioso para a comercialização da música gospel no mercado da música evangélica brasileira, proporcionando neste modelo atual um crescimento qualitativo e quantitativo dos produtos destinados ao público evangélico. A pesquisa identifica nas produções visuais de divulgação e comercialização de CDs, DVDs, sites das produtoras fonográficas, feiras e premiações musicais, os mecanismos utilizados para a construção de um novo paradigma imagético que proporciona no campo religioso, o surgimento de um novo imaginário evangélico mimeticamente construído para alimentar um mercado gospel fomentado pela tríade social: espetáculo, consumo e entretenimento. Desta forma, a analise tem o seu recorte nas mudanças paradigmáticas que surgem a partir dos primeiros cantores e cantoras da década de 1950 até culminar na explosão da música gospel no início da década de 1990.(AU)

A IMPORTÂNCIA DA MÚSICA NA FORMAÇÃO DO INDIVÍDUO: UMA REFLEXÃO SOBRE OS OBSTÁCULOS DA DIFUSÃO DA EDUCAÇÃO MUSICAL NO ESPAÇO ESCOLAR

Este trabalho investigou as interações a entre Música e Matemática, considerando experiências e reflexões de expoentes das ciências exatas, que com seus conceitos de intervalo musical, razões e proporções, consonância, harmonia, temperamento, série harmônica, contribuíram para a estruturação arte da música como ciência. Sob a luz dessa ciência da música, mediante análise descritiva de partitura, contou a história de um país que, segundo o P.I.S.A., se manteve no ranking da educação de 2000 a 2012, revelando interdisciplinaridade das ciências e interações dos conceitos de pensamento analógico, preconizados por Levy e Machado e da teoria das inteligências múltiplas de Gardner. E por fim, se propôs a refletir sobre a importância da educação musical na formação do indivíduo e sobre os obstáculos de sua difusão no espaço escolar.

LASTRO OU PESO-MORTO? UM ESTUDO SOBRE ARTE-EDUCADORES E A RELEVÂNCIA DA DISCIPLINA EDUCAÇÃO ARTÍSTICA EM SUAS TRAJETÓRIAS FORMATIVAS

A frase de uma educadora: maestro a música mudou a vida desse menino foi o elemento que instigou o desenvolvimento da presente pesquisa. Os questionamentos que se seguem a partir dessa constatação abordaram os aspectos inerentes ao ensino da arte nas escolas brasileiras, angariados a partir de dados oficiais que apresentam um reduzido número de arte-educadores frente a legislação pertinente à obrigatoriedade do ensino da música em toda a educação básica a partir de 2011 através da Lei 11.769/08. A pesquisa se desenvolveu diante da suspeita que o ensino da arte nas escolas brasileiras tem se mostrado insuficiente no que diz respeito a promoção do educando em relação ao fazer artístico, culminando com o baixo interesse pela disciplina artes, refletindo posteriormente na formação de um número reduzido de arte-educadores que provavelmente tiveram sua iniciação artística fora do ambiente escolar. Sendo assim interessou a esta pesquisa aferir a relevância da disciplina artes ou educação artística na trajetória formativa dos arte-educadores em música. A pesquisa utilizou como referencial teórico os dados expostos em Barbosa (2008) e Snyders (2008) visando compreender as concepções inerentes ao ensino da arte, da música, e o processo histórico da linguagem artística no Brasil. Visando angariar elementos para a pesquisa foram desenvolvidas entrevistas com arte-educadores, tendo como referência teórica Nóvoa e Finger (2010) além de Bosi (1987). O capítulo I apresenta considerações sobre o fazer artístico, e o desenvolvimento histórico do ensino da arte no Brasil. O capítulo II trata de experiências práticas relacionadas à educação estética. O capítulo III explicita a fundamentação teórica sobre a metodologia utilizada. O capítulo IV apresenta as histórias de vida de três arte-educadores em música, enquanto o capítulo V expõe as devidas conclusões fundamentadas nas entrevistas com os arte-educadores.

Simplified recording of soft contact lens fit

Purpose: To determine the critical fitting characteristics of modern soft contact lens fits and from this to devise a simplified recording scheme. Methods: Ten subjects (aged 28.1 ± 7.4 years) wore eight different modern soft contact lenses. Video was captured and analysed of blink (central and up-gaze), excursion lag (up, down, right and left gaze) and push-up movement, centration and coverage. Results: Lens centration was on average close to the corneal centre. Movement on blink was significantly smaller in up-gaze than in primary-gaze (p<0.001). Lag was greatest in down-gaze and least in up-gaze (p<0.001). Push-up test recovery speed was 1.32±0.73mm/s. Overall lens movement was determined best by assessing horizontal lag, movement on blink in up-gaze and push-up recovery speed. Steeper lens base-curves did not have a significant effect on lens fit characteristics. Contact lens material did influence lens fit characteristics, particularly silicone-hydrogels which generally had lower centration and a faster push-up speed of recovery than HEMA lenses (p<0.05). Conclusion: Lag on vertical gaze, and movement on blink in primary gaze generally provide little extra information on overall lens movement compared to horizontal lag, movement on blink in up gaze and push-up recovery speed. They can therefore be excluded from a simplified recording scheme. A simplified and comprehensive soft contact lens fit recording system could consist of a cross-hairs indicating the centre of the cornea; a circle to indicate the lens centration; a mark on the relevant position of the circle to indicate any limbal incursion; a grade (‘B’) below for movement with blink in up-gaze, a grade (‘L’) to the side for horizontal lag and a grade above (‘P’) for the assessed push-up recovery speed.

Le prix de l'individualité. Maine de Brian, Samuel Taylor Coleridge et la volonté: Deux postétités distinctes

This thesis is concerned with Maine de Biran’s and Samuel Taylor Coleridge’s conceptions of will, and the way in which both thinkers’ posterities have been affected by the central role of these very conceptions in their respective bodies of thought. The research question that animates this work can therefore be divided into two main parts, one of which deals with will, while the other deals with its effects on posterity. In the first pages of the Introduction, I make the case for a comparison between two philosophers, and show how this comparison can bring one closer to truth, understood not in objective, but in subjective terms. I then justify my choice by underlining that, in spite of their many differences, Maine de Biran and Samuel Taylor Coleridge followed comparable paths, intellectually and spiritually, and came to similar conclusions concerning the essential activity of the human mind. Finally, I ask whether it is possible that this very focus on the human will may have contributed to the state of both thinkers’ works and of the reception of those works. This prologue is followed by five parts. In the first part, the similarities and differences between the two thinkers are explored further. In the second part, the connections between philosophy and singularity are examined, in order to show the ambivalence of the will as a foundation for truth. The third part is dedicated to the traditional division between subject and object in psychology, and its relevance in history and in moral philosophy. The fourth part tackles the complexity of the question of influence, with respect to both Maine de Biran’s and Coleridge’s cases, both thinkers being indebted to many philosophers of all times and places, and having to rely heavily on others for the publication, or the interpretation of their own works. The fifth part is concerned with the different aspects of the faculty of will, and primarily its relationship with interiority, as incommensurability, and actual, conditioned existence in a certain historical and spatial context. It ends with a return to the question of will and posterity and an announcement of what will be covered in the main body of the thesis. The main body is divided into three parts:‘L’émancipation’, ‘L’affirmation, and ‘La projection’. The first part is devoted to the way Maine de Biran and Samuel Taylor Coleridge extricated themselves from one epistemological paradigm to contribute to the foundation of another. It is divided in four chapters. The first chapter deals with the aforementioned change of paradigm, as corresponding to the emergence of two separate but associated movements, Romanticism and what the French philosopher refers to as ‘The Age of History’. The second chapter concerns the movement that preceded them, i.e. the Enlightenment, its main features according to both of our thinkers, and the two epistemological models that prevailed under it and influenced them heavily in their early years: Sensationism (Maine de Biran) and Associationism (Coleridge). The third chapter is about the probable influence of Immanuel Kant and his followers on Maine de Biran and Coleridge, and the various facts that allow us to claim originality for both thinkers’ works. In the fourth chapter, I contrast Maine de Biran and Coleridge with other movements and thinkers of their time, showing that, contrary to their respective thoughts, Maine de Biran and Coleridge could not but break free from the then prevailing systematic approach to truth. The second part of the thesis is concerned with the first part of its research question, namely, Maine de Biran’s and Coleridge’s conceptions of the will. It is divided into four chapters. The first chapter is a reflection on the will as a paradox: on the one hand, the will cannot be caused by any other phenomenon, or it is no longer a will; but it cannot be left purely undetermined, as if it is, it is then not different from chance. It thus needs, in order to be, to be contradictorily already moral. The second chapter is a comparison between Maine de Biran’s and Coleridge’s accounts of the origin of the will, where it is found that the French philosopher only observes that he has a will, whereas the English philosopher postulates the existence of this will. The comparison between Maine de Biran’s and Coleridge’s conceptions of the will is pursued in the third chapter, which tackles the question of the coincidence between the will and the self, in both thinkers’ works. It ends with the fourth chapter, which deals with the question of the relationship between the will and what is other to it, i.e. bodily sensations, passions and desires. The third part of the thesis focuses on the second part of its research question, namely the posterity of Maine de Biran’s and Coleridge’s works. It is divided into four chapters. The first chapter constitutes a continuation of the last chapter of the preceding part, in that that it deals with Maine de Biran’s and Coleridge’s relations to the ‘other’, and particularly their potential and actual audience, and with the way these relations may have affected their writing and publishing practices. The second chapter is a survey of both thinkers’ general reception, where it is found that, while Maine de Biran has been claimed by two important movements of thoughts as their initiator, Coleridge has been neglected by the only real movement he could have, or may indeed have pioneered. The third chapter is more directly concerned with the posterities of Maine de Biran’s and Coleridge’s conceptions of will, and attempts to show that the approach to, and the meaning of the will have evolved throughout the nineteenth century, and in the French Spiritualist and the British Idealist movements, from an essentially personal one to a more impersonal one. The fourth chapter is a partial conclusion, whose aim is to give a precise idea of where Maine de Biran and Coleridge stand, in relation to their century and to the philosophical movements and matters we are concerned with. The conclusion is a recapitulation of what has been found, with a particular emphasis on the dialogue initiated between Maine de Biran and Coleridge on the will, and the relation between will and posterity. It suggests that both thinkers have to pay the price of a problematic reception for the individuality that pervades their respective works, and goes further in suggesting that s/he who chooses to found his individuality on the will is bound to feel this incompleteness in his/her own personal life more acutely than s/he who does not. It ends with a reflection on fixedness and movement, as the two antagonistic states that the theoretician of the will paradoxically aspires to.

Advances in anterior segment imaging

PURPOSE OF REVIEW: Imaging of the crystalline lens and intraocular lens is becoming increasingly more important to optimize the refractive outcome of cataract surgery, to detect and manage complications and to ascertain advanced intraocular lens performance. This review examines recent advances in anterior segment imaging. RECENT FINDINGS: The main techniques used for imaging the anterior segment are slit-lamp biomicroscopy, ultrasound biomicroscopy, scheimpflug imaging, phakometry, optical coherence tomography and magnetic resonance imaging. They have principally been applied to the assessment of intraocular lens centration, tilt, position relative to the iris and movement with ciliary body contraction. SUMMARY: Despite the advances in anterior chamber imaging technology, there is still the need for a clinical, high-resolution, true anatomical, noninvasive technique to image behind the peripheral iris. © 2007 Lippincott Williams & Wilkins, Inc.

"Crack down on the celebrity junkies": does media coverage of celebrity drug use pose a risk to young people?

This study analysed news media content to examine the role played by celebrity drug use in young people's perceptions of drug use. We know that young people have access to discourses of drug use through music and other media which may emphasise short term gains (of pleasure or sexual success) over longer term health and social problems. This study goes beyond a simple modelling approach by using Media Framing Analysis (MFA) to take an in-depth look at the messages themselves and how they are 'framed'. New stories about Amy Winehouse's drug use were used and we conducted focus groups with young people asking them questions about drugs, celebrity and the media. Frames identified include: 'troubled genius', 'losing patience' and 'glamorization or gritty realism'. Initially, the press championed Winehouse's musical talent but soon began to tire of her recklessness; the participants tended to be unimpressed with Winehouse's drug use, characterising her as a promising artist who had 'gone off the rails'. Young people were far more critical of Winehouse than might be expected, demonstrating that concerns about the influence of celebrity drug use and its impact on future health risk behaviour among young people may have been over-simplified and exaggerated. This study illustrates the need to understand young people and their frames of reference within popular culture when designing drug awareness information relevant to them. Furthermore, it indicates that critical media skills analysis may contribute to health risk education programmes related to drug use.
