The relationship of cervical joint position error to balance and eye movement disturbances in persistent whiplash

Cervical joint position error (JPE) has been used as a measure of cervical afferent input to detect disturbances in sensori-motor control as a possible contributor to a neck pain syndrome. This study aimed to investigate the relationship between cervical JPE, balance and eye movement control. It was of particular interest whether assessment of cervical ME alone was sufficient to signal the presence of disturbances in the two other tests. One hundred subjects with persistent whiplash-associated disorders (WADs) and 40 healthy controls subjects were assessed on measures of cervical JPE, standing balance and the smooth pursuit neck torsion test (SPNT). The results indicated that over all subjects, significant but weak-to-moderate correlations existed between all comfortable stance balance tests and both the SPNT and rotation cervical ME tests. A weak correlation was found between the SPNT and right rotation cervical JPE. An abnormal rotation cervical JPE score had a high positive prediction value (88%) but low sensitivity (60%) and specificity (54%) to determine abnormality in balance and or SPNT test. The results suggest that in patients with persistent WAD, it is not sufficient to measure ME alone. All three measures are required to identify disturbances in the postural control system.

Changes in head and neck position have a greater effect on elbow joint position sense in people with whiplash-associated disorders

Background: It has been shown that perception of elbow joint position is affected by changes in head and neck position. Further, people with whiplash-associated disorders (WAD) present with deficits in upper limb coordination and movement. Objectives: This study is aimed to determine whether the effect of changes in head position on elbow joint position error (JPE) is more pronounced in people with WAD, and to determine whether this is related to the participant's pain and anxiety levels. Methods: Nine people with chronic and disabling WAD and 11 healthy people participated in this experiment. The ability to reproduce a position at the elbow joint was assessed after changes in the position of the head and neck to 30 degrees, and with the head in the midline. Pain was monitored in WAD participants. Results: Absolute elbow JPE with the head in neutral was not different between WAD and control participants (P = 0.5). Changes in the head and neck position increased absolute elbow JPE in the WAD group (P < 0.05), but did not affect elbow JPE in the control group (P = 0.4). There was a connection between pain during testing and the effect of changes in head position on elbow JPE (P < 0.05). Discussion: Elbow JPE is affected by movement of the head and neck, with smaller angles of neck rotation in people with WAD than in healthy individuals. This observation may explain deficits in upper limb coordination in people with WAD, which may be due to the presence of pain or reduced range of motion in this population.

Clinical tests of musculoskeletal dysfunction in the diagnosis of cervicogenic headache

Persistent intermittent headache is a common disorder and is often accompanied by neck aching or stiffness, which could infer a cervical contribution to headache. However, the incidence of cervicogenic headache is estimated to be 14-18% of all chronic headaches, highlighting the need for clear criterion of cervical musculoskeletal impairment to identify cervicogenic headache sufferers who may benefit from treatments such as manual therapy. This study examined the presence of cervical musculoskeletal impairment in 77 subjects, 27 with cervicogenic headache, 25 with migraine with aura and 25 control subjects. Assessments included a photographic measure of posture, range of movement, cervical manual examination, pressure pain thresholds, muscle length, performance in the cranio-cervical flexion test and cervical kinaesthetic sense. The results indicated that when compared to the migraine with aura and control groups who scored similarly in the tests, the cervicogenic headache group had less range of cervical flexion/extension (P = 0.048) and significantly higher incidences of painful upper cervical joint dysfunction assessed by manual examination (all P < 0.05) and muscle tightness (P < 0.05). Sternocleidomastoid normalized EMG values were higher in the latter three stages of the cranio-cervical flexion test although they failed to reach significance. There were no between group differences for other measures. A discriminant analysis revealed that manual examination could discriminate the cervicogenic headache group from the other subjects (migraine with aura and control subjects combined) with an 80% sensitivity.

Finding event-oriented patterns in long temporal sequences

A major task of traditional temporal event sequence mining is to find all frequent event patterns from a long temporal sequence. In many real applications, however, events are often grouped into different types, and not all types are of equal importance. In this paper, we consider the problem of efficient mining of temporal event sequences which lead to an instance of a specific type of event. Temporal constraints are used to ensure sensibility of the mining results. We will first generalise and formalise the problem of event-oriented temporal sequence data mining. After discussing some unique issues in this new problem, we give a set of criteria, which are adapted from traditional data mining techniques, to measure the quality of patterns to be discovered. Finally we present an algorithm to discover potentially interesting patterns.

A LITURGIA NO CONTEXTO URBANO: APONTAMENTOS PARA A PRÁXIS PASTORAL NA COMUNIDADE DE HELIÓPOLIS

Esta pesquisa propõe-se a analisar a liturgia no contexto urbano, e a forma como a práxis pode influir e se articular com a liturgia cristã construída na cidade, especialmente em áreas empobrecidas e que experimentam as contradições resultantes de um modelo econômico excludente e concentrador de renda. Assim, a pesquisa busca apontar para o desenvolvimento da práxis pastoral litúrgica, tendo como espaço de referência a área da Comunidade de Heliópolis, São Paulo, a segunda maior favela do Brasil. A práxis é a atividade reflexiva e material do ser humano, isto é, ação transformadora que deve insistir na opção preferencial pelos pobres e excluídos. A pastoral litúrgica que tenha o seu referencial na práxis irá, portanto, criar ações que animem as esperanças do povo que celebra, favorecendo a organização e a sensibilização para as lutas sociais necessárias para a superação da exclusão, devolvendo a dignidade aos seres humanos. A pesquisa se desenvolve em três etapas: primeiramente, buscam-se as conceituações teóricas de práxis e urbanizações; em segundo lugar, se analisa o caminho da ocupação da área de Heliópolis; e por último os apontamentos para a práxis pastoral litúrgica no contexto urbano. O resultado será um conjunto de referenciais gerais históricos e teóricos capazes de sustentar uma pastoral litúrgica que contribua para as esperanças humanas e a criação de um novo paradigma de sociedade fundamentado na justiça e na igualdade.(AU)

JAVÉ, O PASTOR QUE ABRIGA EM BELAS PASTAGENS CONTRIBUIÇÃO EXEGÉTICA SOBRE O SALMO 23

Na América Latina temos pouca bibliografia sobre o Salmo 23. No entanto, contamos com alguns pesquisadores que podem dialogar academicamente com cientistas europeus sobre nosso objeto de estudo. Apesar do grande atrativo deste texto no mundo pastoral de nosso continente, o aporte exegético deste Salmo estava em dívida, o que se tem convertido numa de nossa justificação científica para o estudo do Salmo 23. O Salmo 23 se incrusta dentro do saltério. É poesia hebraica, a que se caracteriza pela repetição do sentido de suas frases. Seu conteúdo está nas entrelinhas pelo uso freqüente de imagens, símbolos e figuras. Por estas e outras razões é difícil assinalar sua data de origem, mas deve ser pré-exílico. Nosso texto revela, como lugar vital, uma comunidade litúrgica. Essa comunidade está localizada no templo de Jerusalém. Ali se encontram, por sua vez, sacerdotes, levitas, intelectuais orgânicos; enfim, pessoas que têm testemunhado de perto a controvérsia de uma pessoa refugiada no templo, a que tem achado no santuário um lugar de amparo. Desde aqui deduzimos que o Salmo 23 foi escrito por alguém de sensibilidade poética, inspirado na vida do asilado. O salmista tem experimentado os cuidados de Javé. Ali, no templo, na área do reino de Javé, seus ameaçadores não podem capturá-lo. Os motivos de perseguição podem sugerir assuntos de dívidas e, ao mesmo tempo, assuntos de justiça. Uma vez no santuário, não carece de nada, porque seu pastor/rei lhe fornece o que precisa, isto é, comida, bebida, proteção, segurança, dignidade e fraternidade. Os agressores são testemunhas do estado de felicidade de seu inimigo, mas não podem fazer-lhe nada. Por isso o salmista, não teme e, na presença de Javé, encontra seu consolo. Javé, como pastor/rei, hospeda a seu protegido. Pela inocência reconhecida do refugiado, nasce o ambiente de festa, porque a comunidade litúrgica celebra a salvação alcançada. As graças recebidas têm para o salmista uma repercussão comunitária, o bem e a solidariedade que experimentou voltarão aos que o circundam, não por obrigação e sim por gratidão. Por assuntos de segurança e agradecimento o salmista deseja permanecer na casa de Javé.(AU)

O SILÊNCIO ESTÉTICO COMO ELEMENTO COMUNICACIONAL NA DIREÇÃO DE ARTE DO JOGO DIGITAL JOURNEY

Esta pesquisa propõe a abordagem teórica do silêncio como elemento comunicacional, como um elemento ligado a materialidade da linguagem, como um meio capaz de produzir ritmo narrativo e de edificar as bases projetuais destinadas ao desenvolvimento e a implementação da direção de arte em um projeto voltado a criação de Journey, um jogo digital independente para os videogames de sétima geração. O silêncio em Journey foi observado como elemento compositivo de linguagem, isto é, como aquilo que intencionalmente não foi dito, mas que conseguiu produzir algum tipo de efeito comunicacional no percurso da narrativa proposta para a trama. Assim, descobrimos os ambientes e os personagens que compõem o universo lúdico deste jogo digital por meio de um estudo de caso e da metáfora do silêncio, abordando os sistemas narrativos, as técnicas de direção de arte e as relações projetuais estabelecidas a partir deste contexto. Este é o objetivo central deste trabalho, traduzir o silêncio e suas ausências em um elemento comunicador, transformador da percepção e da sensibilidade dos jogadores por meio das narrativas e da direção de arte de uma expressão artística em forma de videogame.

A SENSIBILIDADE DO OLHAR MULTIRREFERENCIAL ABRINDO CAMINHOS EM DIREÇÃO AO AUTOR-CIDADÃO

O estudo pretende debater a idéia de sujeito a partir do cruzamento das idéias de autonomia, autoria e autor-cidadão como eixo teórico para, a partir da abordagem multirreferencial, indagar sobre de que maneiras é possível contribuir para a formação de sujeitos autônomos considerando a prática em uma universidade privada confessional. O sujeito aqui é apresentado não na perspectiva de um corpo biológico e físico, mas como projeto, considerando a historicidade, sociabilidade e, também, a questão da psique do ser humano. O objetivo do trabalho é analisar a formação do sujeito tendo em vista a proposta pedagógica da UMESP UNIVERSIDADE METODISTA DE SÃO PAULO. Esta opção justifica-se essencialmente pelo fato da escola apresentar uma proposta educacional diferenciada, que visa a formação cidadã. Os conceitos de instituição e autonomia são de extrema relevância para analisar no contexto da pesquisa proposta as representações e as práticas legítimas, bem como a necessidade de ressignificação da idéia de cidadania, diante das exigências da vida contemporânea. Trata-se, portanto, de uma pesquisa qualitativa de cunho exploratório. Quanto aos procedimentos metodológicos foi realizada a observação participante e com a aplicação de um roteiro qualificado buscou-se ouvir alunos da comunidade acadêmica. Foi possível perceber claramente as intenções ligadas à confessionalidade retratadas no Projeto Pedagógico da UMESP. Quanto às intenções dos alunos, observou-se a preocupação com a formação profissional. Tendo em vista nosso entendimento a respeito do exercício da cidadania a partir da autonomia do sujeito, estendemos nosso olhar para todos os atores sociais envolvidos. Observamos que é possível realizar um trabalho em direção ao autorcidadão porque o aluno, em geral, está aberto a transformar-se. A questão é relacional. Tem a ver de fato com a maneira como o ensino acontece. Professores e alunos devem encontrar-se como sujeitos em permanente construção, implicados. A educação pode desenvolver pessoas críticas e autônomas, sujeitos autores de suas próprias vidas atuando de acordo com seus desejos e conscientes de suas reais necessidades e responsabilidades.(AU)

PROVOCAÇÕES PARA UMA EDUCAÇÃO SENSÍVEL: O OLHAR DO GESTOR PARA O NÃO DITO

Ser sujeito e objeto de seu fazer de pesquisador/educador. Essa é a proposta de pesquisa realizada por este trabalho, por meio da narrativa de história de vida e da implicação do olhar do educador, para compreender a importância da sensibilidade na constituição do sujeito-autor, em uma gestão sensível e democrática. No processo de formação de cidadãos-autores, é preciso considerar a subjetividade como fundamental na formação do sujeito-autor. A relação de ensino-aprendizagem, relação entre sujeitos, para que seja significativa e democrática deve considerar que, em parte, essa relação se dá na intersubjetividade. E como forma de conhecermos nossa sensibilidade, a experiência em uma linguagem artística, diante das funções pedagógicas que a arte possui, surge como uma possibilidade de construção de sentido.(AU)

Transgressing community:the case of Muslims in a twenty-first-century British city

This paper draws on ethnographic research carried out in Birmingham, UK – a city significant for its sizeable Muslim population and its iconic role in the history of minority ethnic settlement in Britain – to consider how associations of place and ethnicity work in different ways to inform ideas about ‘Muslim community’ in twenty-first-century Britain. The paper charts happenings around a local event in an area of majority Asian settlement and how representations of the area as a place of Muslim community were used to implicate it in the ‘war on terror’. The paper goes on to show how this sensibility is disrupted by Muslims themselves through alternative engagements with space and ethnicity. The paper argues that these offer a ground for making Muslim community in ways that actively engage with histories and patterns of ethnic settlement in the city rather than being determined by them.

Perceptions of character education in a Seventh-day Adventist school

Character education has been viewed by many educators as having significant historical, academic, and social value. Many stakeholders in education argue for character development as a curricular experience. While understanding the degree to which character education is of worth to stakeholders of institutions is important, understanding students, teachers, and administrators perspectives from their lived experiences is likewise significant. The purpose of this phenomenological study was to gain a deeper understanding of character education within a Biblical framework environment by examining the lived experiences of students, administrators, and teachers of a Seventh-day Adventist School. Phenomenology describes individuals' daily experiences of phenomena, the manner in which these experiences are structured, and focuses analysis on the perspectives of the persons having the experience (Moustakas, 1994). This inquiry was undertaken to answer the question: What are the perceptions of students, teachers, and an administrator toward character education in a Seventh-day Adventist school setting? Ten participants (seven students and three adults) formed the homogeneous purposive sample, and the major data collection tool was semi-structured interviews (Patton, 1990; Seidman, 2006). Three 90-minute open-ended interviews were conducted with each of the participants. Data analysis included a three-phase process of description, reduction and interpretation. The findings from this study revealed that participants perceived that their involvement in the school's character education program decreased the tendency to violence, improved their conduct and ethical sensibility, enhanced their ability to engage in decision-making concerning social relationships and their impact on others, brought to their attention the emerging global awareness of moral deficiency, and fostered incremental progress from practice and recognition of vices to their acquisition of virtues. The findings, therefore, provide a model for teaching character education from a Seventh-day Adventist perspective. The model is also relevant for non-Seventh day Adventists who aspire to teach character education as a means to improving social and moral conditions in schools.

Firefly curios and sundry lights

Firefly Curios and Sundry Lights contains 33 poems and 55 pages, mostly free verse lyric narratives issuing from various geographic, emotional, and temporal landscapes. The book is divided into four sections which might roughly be titled: "before," examining themes of childhood and death: "on-the-road," relaying the compulsion to travel, "odd-and- ends-limbo," including pieces which have no context within the time line; and "in-one- place-for-now," reflecting modes of communication, ordering, and longing. Other concerns include speculations about existence, observations of nature, and the importance of science as a means of apprehending the world. The work reveals a belief in the interconnectedness of mind and matter, combines seriousness and humor, and displays a sonic sensibility. These poems of solitude and observation are themselves vehicles, their motion a means of dislocation in order to find the self. Firefly Curios and Sundry Lights is smaller than a bread box and you can dance to it.

UV-induced melanoma mouse model dependent on endothelin 3 over-expression

Melanoma is one of the most aggressive types of cancer. It originates from the transformation of melanocytes present in the epidermal/dermal junction of the human skin. It is commonly accepted that melanomagenesis is influenced by the interaction of environmental factors, genetic factors, as well as tumor-host interactions. DNA photoproducts induced by UV radiation are, in normal cells, repaired by the nucleotide excision repair (NER) pathway. The prominent role of NER in cancer resistance is well exemplified by patients with Xeroderma Pigmentosum (XP). This disease results from mutations in the components of the NER pathway, such as XPA and XPC proteins. In humans, NER pathway disruption leads to the development of skin cancers, including melanoma. Similar to humans afflicted with XP, Xpa and Xpc deficient mice show high sensibility to UV light, leading to skin cancer development, except melanoma. The Endothelin 3 (Edn3) signaling pathway is essential for proliferation, survival and migration of melanocyte precursor cells. Excessive production of Edn3 leads to the accumulation of large numbers of melanocytes in the mouse skin, where they are not normally found. In humans, Edn3 signaling pathway has also been implicated in melanoma progression and its metastatic potential. The goal of this study was the development of the first UV-induced melanoma mouse model dependent on the over-expression of Edn3 in the skin. The UV-induced melanoma mouse model reported here is distinguishable from all previous published models by two features: melanocytes are not transformed a priori and melanomagenesis arises only upon neonatal UV exposure. In this model, melanomagenesis depends on the presence of Edn3 in the skin. Disruption of the NER pathway due to the lack of Xpa or Xpc proteins was not essential for melanomagenesis; however, it enhanced melanoma penetrance and decreased melanoma latency after one single neonatal erythemal UV dose. Exposure to a second dose of UV at six weeks of age did not change time of appearance or penetrance of melanomas in this mouse model. Thus, a combination of neonatal UV exposure with excessive Edn3 in the tumor microenvironment is sufficient for melanomagenesis in mice; furthermore, NER deficiency exacerbates this process.^
