Leitura recombinativa de palavras de inglês com onset e rime em braille e alfabeto romano em relevo por cegos

Estudos têm demonstrado que o ensino explícito de discriminações de sílaba promove a emergência da leitura das sílabas de ensino, das sílabas com recombinação das letras das sílabas de ensino e a leitura de palavras formadas pelas sílabas de ensino e recombinadas. As pesquisas sobre leitura recombinativa em inglês têm demonstrado a emergência de leitura de novas palavras formadas pela recombinação de onset e rime. A presente pesquisa investigou se o ensino de leitura de palavras monossilábicas com recombinação de onset e rime pode promover a leitura de novas palavras em inglês, impressas em braille e alfabeto romano impressas em relevo. Três adultas cegas participaram do estudo que compreendeu três etapas. A Etapa I compreendeu um préteste, três sequências de ensino gradual de discriminações condicionais de palavras simples, intercaladas com fases de teste de leitura textual das palavras de ensino e recombinadas. Na Etapa Ic era aplicado um teste de discriminações condicionais entre palavra impressa em braille e palavra do alfabeto romano impressa em relevo. Nas Etapas II e III eram aplicados testes de leitura textual das palavras recombinadas simples (Etapa II) e compostas (Etapa III) e nomeação dos objetos correspondentes. Após esse teste, eram testadas as relações entre palavras ditadas e objetos (AB), palavras ditadas e palavras impressas (AC, AD), objetos e palavras impressas (BC, BD) e palavras impressas e objetos (CB, DB), que documentam a leitura com compreensão. Caso as relações AB não ocorressem, eram ensinadas. Após o teste das relações de equivalência BC, CB, BD e DB eram verificados os desempenhos de cópia e ditado. Nas Etapas Ia, IIa e IIIa, as palavras eram impressas em Braille; nas Etapas Ib, IIb e IIIb, em alfabeto romano em relevo. Todas as participantes alcançaram prontamente os critérios em todas ou na maioria das fases de ensino e teste. Todas as participantes apresentaram a leitura textual e com compreensão de quase todas as palavras simples recombinadas e compostas, impressas em braille e do alfabeto romano em relevo. Os resultados mostram a emergência de leitura recombinativa após o ensino de discriminações condicionais de palavras monossílabas formadas por onset e rime.

The use of visualization, onset-and-rime, story read-alouds, and discussion to improve diverse first graders' vocabulary and comprehension

It has long been known that vocabulary is essential in the development of reading. Because vocabulary leading to increased comprehension is important, it necessary to determine strategies for ensuring that the best methods of teaching vocabulary are used to help students make gains in vocabulary leading to reading comprehension. According to the National Reading Panel, multiple strategies that involve active engagement on the part of the student are more effective than the use of just one strategy. The purpose of this study was to determine if students' use of visualization, student-generated pictures of onset-and-rime-patterned vocabulary, and story read-alouds with discussion, would enable diverse first-grade students to increase their vocabulary and comprehension. In addition, this study examined the effect of the multimodal framework of strategies on English learners (ELs). This quasi-experimental study (N=69) was conducted in four first-grade classrooms in a low socio-economic school. Two treatment classes used a multimodal framework of strategies to learn weekly vocabulary words and comprehension. Two comparison classrooms used the traditional method of teaching weekly vocabulary and comprehension. Data sources included Florida Assessments for Instruction in Reading (FAIR), comprehension and vocabulary scores, and weekly MacMillan/McGraw Hill Treasures basal comprehension questions and onset-and-rime vocabulary questions. This research determined that the treatment had an effect in adjusted FAIR comprehension means by group, with the treatment group (adj M = 5.14) significantly higher than the comparison group ( adj M = -8.26) on post scores. However, the treatment means did not increase from pre to post, but the comparison means significantly decreased from pre to post as the materials became more challenging. For the FAIR vocabulary, there was a significant difference by group with the comparison adjusted post mean higher than the treatment's, although both groups significantly increased from pre to post. However, the FAIR vocabulary posttest was not part of the Treasures vocabulary, which was taught using the multimodal framework of strategies. The Treasures vocabulary scores were not significantly different by group on the assessment across the weeks, although the treatment means were higher than those of the comparison group. Continued research is needed in the area of vocabulary and comprehension instructional methods in order to determine strategies to increase diverse, urban students' performance.

Ensino de discriminações de palavras com Onset/Rime e a emergência da leitura recombinativa em inglês da simbologia braille e do alfabeto romano em relevo em cegos

Estudos recentes têm documentado que o ensino explícito de discriminação de sílabas promove a emergência da leitura das sílabas de ensino e das sílabas com recombinação das letras das sílabas de ensino. Promove também prontamente a leitura de palavras, formadas pelas sílabas de ensino e recombinadas. Estudos têm demonstrado a leitura de palavras novas com recombinação de onset e rime como fator facilitador quando a língua inglesa é ensinada como língua materna. O aprendizado do inglês por cegos tem sido documentado como um fator de inclusão. O presente estudo investigou se o ensino de discriminação de palavras com segmentação onset/rime facilita a leitura de novas palavras em inglês, como língua estrangeira, usando o Braille e o alfabeto romano em relevo. Três cegas, leitoras fluentes em Braille, participaram. O estudo compreendeu três etapas. Etapa I: Etapa Ia (auditivo/Braille), Etapa Ib (Braille/alfabeto romano em relevo) e Etapa Ic (auditivo/alfabeto romano em relevo). A Etapa I (a e b) compreendeu um pré-teste, fases de ensino de discriminações condicionais de palavras simples e testes de leitura textual das palavras simples e recombinadas. Na Etapa Ic era aplicado um teste de discriminações condicionais. Nas Etapas II e III eram aplicados testes de leitura textual das palavras simples recombinadas (Etapa II) e compostas (Etapa III) e nomeação de objetos. Eram testadas as relações entre palavras ditadas e objetos (AB), palavras ditadas e palavras impressas (AC), objetos e palavras impressas (BC) e palavras impressas e objetos (CB) que documentam a leitura com compreensão das palavras impressas em Braille e no alfabeto romano em relevo, e ainda, a emergência de cópia e ditado. As três participantes atingiram o critério de acertos em todas as fases em todas as etapas. Os resultados mostraram que o ensino de discriminações de palavras com a segmentação onset/rime facilita a emergência da leitura recombinativa em inglês, como língua estrangeira, com cegos falantes do português, usando o Braille e o alfabeto romano em relevo, mostraram ainda a emergência da leitura com compreensão com os procedimentos de equivalência de estímulos. Estes resultados indicam que novas tecnologias de ensino, que permitam uma maior inclusão de pessoas cegas na comunidade, podem ser geradas.

La instrucción en habilidades metafonológicas del inglés como lengua extranjera : su incidencia en la lectura y la producción oral en aprendices de 7-8 años.

Fundamentar empíricamente la adecuación de un programa de enseñanza que incluye el tratamiento de los aspectos fonológicos de la nueva lengua de una forma analítica. Desarrollar en los aprendices habilidades fonológicas y metafonológicas que permitan una adquisición adecuada de la pronunciación de la lengua inglesa, así como el aprendizaje de las correspondencias grafema-fonema específicas de su sistema ortográfico. Se basan en la siguiente hipótesis: los alumnos que sigan con aprovechamiento un programa de entrenamiento metafonológico de lengua inglesa, al comenzar el aprendizaje en dicha lengua, alcanzarán un nivel de dominio fonológico y lectoescritor superior al de un grupo de control no entrenado en dichos aspectos. 46 alumnos-as de segundo curso de Enseñanza Primaria, pertenecientes a dos centros públicos de la ciudad de Murcia. Se analizan los principios, teorías y datos empíricos pertenecientes al campo de la Percepción y Articulación. La investigación se centra en el estudio de la adquisición de los aspectos fonológicos y metafonológicos de la nueva lengua y su influencia en el aprendizaje de la pronunciación, la lectura y el deletreo. Los procedimientos utilizados para conseguir los objetivos, se basan en el análisis metafonológico y articulatorio a nivel de fonemas y de unidades intrasilábicas de 'onset' y 'rime'. Se comparan los efectos del programa experimental de enseñanza, con los de un programa clásico, aplicado a dos grupos de alumnos respectivamente, igualados al comienzo del estudio en las variables consideradas para este. La evaluación final incluye un conjunto de test metafonológicos y varias pruebas específicas. Test SIPA2. Prueba de Lebene. Prueba T. Se ha probado que la adquisición de habilidades para el análisis metafonológico, incluidos los aspectos articulatorios, ejerce un importante papel en la adquisición del sistema fonológico de una lengua extranjera. Esta adquisición repercute en las capacidades comunicativas de los aprendices. Las repercusiones que el conocimiento metafonológico tiene en la lectura y la escritura, establecen una base sólida para progresar en los procedimientos que permiten la fluidez en el dominio de la lengua escrita. Se contribuye a un mejor conocimiento de las vías a través de las cuales puede ser instaurado un nuevo sistema fonológico de la lengua inglesa. Los datos aportados apoyan la idea de la necesidad de un conocimiento analítico para el desarrollo de las habilidades básicas de lectura y escritura. Se dispone de un programa de enseñanza secuencial, que permite llevar a la práctica los principios metodológicos en los que se basa el estudio y que han aprobado su eficacia, por ello, se considera apropiado la difusión de dicho programa entre los profesores de inglés de los primeros niveles de enseñanza..

A brief motivational intervention for substance misuse in recent-onset psychosis

Substance misuse is common in early psychosis, and impacts negatively on outcomes. Little is known about effective interventions for this population. We report a pilot study of brief intervention for substance misuse in early psychosis (Start Over and Survive: SOS), comparing it with Standard Care (SC). Twenty-five in-patients aged 18-35 years with early psychosis and current misuse of non-opioid drugs were allocated randomly to conditions. Substance use and related problems were assessed at baseline, 6 weeks and 3, 6 and 12 months. Final assessments were blind to condition. All 13 SOS participants who proceeded to motivational interviewing reported less substance use at 6 months, compared with 58% (7/12) in SC alone. Effects were well maintained to 12 months. However, more SOS participants lived with a relative or partner, and this also was associated with better outcomes. Engagement remained challenging: 39% (16/41) declined participation and 38% (5/13) in SOS only received rapport building. Further research will increase sample size, and address both engagement and potential confounds.

Are there any true adult-onset offenders?

In the extant literature, adult-onset offending has usually been identified using official sources. It is possible, however, that many of the individuals identified would have had unofficial histories of prior offending. To investigate this issue, the men from the Cambridge Study in Delinquent Development (CSDD) were examined. The CSDD is a prospective longitudinal study of men from inner-city London, followed from age 8 to age 48. Onset of offending was identified using official records and then the self-reported offending of the adult-onset offender group (with a first conviction at age 21 or later) was compared to others. All the adult-onset offenders self-reported some previous offending in childhood and adolescence but most of this offending was not sufficiently frequent or serious to lead to a conviction in practice. About one-third of adult-onset offenders were considered to be self-reported delinquents who were realistically in danger of being convicted because of the frequency of their offending. For some, the adjudication by the criminal justice system was simply the first time that their ongoing pattern of offending had been detected. Their lack of detection was because the types of offences they were committing had lower detection rates.

Weaving yarns : the lived experience of Indigenous Australians with adult-onset disability in Brisbane

Indigenous Australians have lower levels of health than mainstream Australians and (as far as statistics are able to indicate) higher levels of disability, yet there is little information on Indigenous social and cultural constructions of disability or the Indigenous experience of disability. This research seeks to address these gaps by using an ethnographic approach, couched within a critical medical anthropology (CMA) framework and using the “three bodies” approach, to study the lived experience of urban Indigenous people with an adult-onset disability. The research approach takes account of the debate about the legitimacy of research into Indigenous Australians, Foucault‟s governmentality, and the arguments for different models of disability. The possibility of a cultural model of disability is raised. After a series of initial interviews with contacts who were primarily service providers, more detailed ethnographic research was conducted with three Indigenous women in their homes and with four groups of Indigenous women and men at an Indigenous respite centre. The research involved multiple visits over a period extending more than two years, and the establishment of relationships with all participants. An iterative inductive approach utilising constant comparison (i.e. a form of grounded theory) was adopted, enabling the generation and testing of working hypotheses. The findings point to the lack of an Indigenous construct of disability, related to the holistic construction of health among Indigenous Australians. Shame emerges as a factor which affects the way that Indigenous Australians respond to disability, and which operates in apparent contradiction to expectations of community support. Aspects of shame relate to governmentality, suggesting that self-disciplinary mechanisms have been taken up and support the more obvious exertion of government power. A key finding is the strength of Indigenous identity above and beyond other forms of identification, e.g. as a person with a disability, expressed in forms of resistance by individuals and service providers to the categories and procedures of the mainstream. The implications of a holistic construction of health are discussed in relation to the use of CMA, the interpretation of the “three bodies”, governmentality and resistance. The explanatory value of the concept of sympatricity is discussed, as is the potential value of a cultural model of disability which takes into account the cultural politics of a defiant Indigenous identity.

Psychotic symptom and cannabis relapse in recent-onset sychosis

Background Cannabis use appears to exacerbate psychotic symptoms and increase risk of psychotic relapse. However, the relative contribution of cannabis use compared with other risk factors is unclear. The influence of psychotic symptoms on cannabis use has received little attention. Aims To examine the influence of cannabis use on psychotic symptom relapse and the influence of psychotic symptom severity on relapse in cannabis use in the 6 months following hospital admission. Method At baseline, 84 participants with recent-onset psychosis were assessed and 81 were followed up weekly for 6 months, using telephone and face-to-face interviews. Results A higher frequency of cannabis use was predictive of psychotic relapse, after controlling for medication adherence, other substance use and duration of untreated psychosis. An increase in psychotic symptoms was predictive of relapse to cannabis use, and medication adherence reduced cannabis relapse risk. Conclusions The relationship between cannabis use and psychosis may be bidirectional, highlighting the need for early intervention programmes to target cannabis use and psychotic symptom severity in this population.

Effects of Mobile Phone Distraction at the Onset of Amber Light: Analysis of Driving Simulator Data

Distraction whilst driving on an approach to a signalized intersection is particularly dangerous, as potential vehicular conflicts and resulting angle collisions tend to be severe. This study examines the decisions of distracted drivers during the onset of amber lights. Driving simulator data were obtained from a sample of 58 drivers under baseline and handheld mobile phone conditions at the University of IOWA - National Advanced Driving Simulator. Explanatory variables include age, gender, cell phone use, distance to stop-line, and speed. An iterative combination of decision tree and logistic regression analyses are employed to identify main effects, non-linearities, and interactions effects. Results show that novice (16-17 years) and younger (18-25 years) drivers’ had heightened amber light running risk while distracted by cell phone, and speed and distance thresholds yielded significant interaction effects. Driver experience captured by age has a multiplicative effect with distraction, making the combined effect of being inexperienced and distracted particularly risky. Solutions are needed to combat the use of mobile phones whilst driving.

Quantitative studies of lower motor neuron degeneration in amyotrophic lateral sclerosis : Evidence for exponential decay of motor unit numbers and greatest rate of loss at the site of onset

Objective: To use our Bayesian method of motor unit number estimation (MUNE) to evaluate lower motor neuron degeneration in ALS. Methods: In subjects with ALS we performed serial MUNE studies. We examined the repeatability of the test and then determined whether the loss of MUs was fitted by an exponential or Weibull distribution. Results: The decline in motor unit (MU) numbers was well-fitted by an exponential decay curve. We calculated the half life of MUs in the abductor digiti minimi (ADM), abductor pollicis brevis (APB) and/or extensor digitorum brevis (EDB) muscles. The mean half life of the MUs of ADM muscle was greater than those of the APB or EDB muscles. The half-life of MUs was less in the ADM muscle of subjects with upper limb than in those with lower limb onset. Conclusions: The rate of loss of lower motor neurons in ALS is exponential, the motor units of the APB decay more quickly than those of the ADM muscle and the rate of loss of motor units is greater at the site of onset of disease. Significance: This shows that the Bayesian MUNE method is useful in following the course and exploring the clinical features of ALS. 2012 International Federation of Clinical Neurophysiology.

A novel DRD2 single-nucleotide polymorphism associated with schizophrenia predicts age of onset : HapMap tag-single-nucleotide polymorphism analysis

Background: Dopamine D2 receptor (DRD2) is thought to be critical in regulating the dopaminergic pathway in the brain which is known to be important in the aetiology of schizophrenia. It is therefore not surprising that most antipsychotic medication acts on the Dopamine D2 receptor. DRD2 is widely expressed in brain, levels are reduced in brains of schizophrenia patients and DRD2 polymorphisms have been associated with reduced brain expression. We have previously identified a genetic variant in DRD2, rs6277 to be strongly implicated in schizophrenia susceptibility. Methods: To identity new associations in the DRD2 gene with disease status and clinical severity, we genotyped seven single nucleotide polymorphisms (SNPs) in DRD2 using a multiplex mass spectrometry method. SNPs were chosen using a haplotype block-based gene-tagging approach so the entire DRD2 gene was represented. Results: One polymorphism rs2734839 was found to be significantly associated with schizophrenia as well as late onset age. Individuals carrying the genetic variation were more than twice as likely to have schizophrenia compared to controls. Conclusions: Our results suggest that DRD2 genetic variation is a good indicator for schizophrenia risk and may also be used as a predictor age of onset.
