How to assess, plan and teach shared and guided reading and writing 1 : key stage one, primary 1-3.

El desarrollo de la alfabetización infantil se inicia desde el momento en que los padres, hablan, cantan y leen a sus bebés. Estas buenas experiencias son las bases sobre las que seguir, pues, después, aprenden a jugar con los libros, a disfrutar con sus imágenes y sus páginas, a imitar a los adultos en la lectura, a garabatear y a escribir como ellos. Aunque, algunos niños hayan carecido de estas experiencias en su hogar, al incorporarse a la escuela, es necesario darles todas las oportunidades posibles para observar a sus compañeros lectores y escritores, interactuar con los libros y experimentar ellos mismos con la lectura y la escritura.

How to assess, plan and teach shared and guided reading and writing 2 : key stage two, primary 4-7.

En esta etapa del desarrollo de la alfabetización, la mayoría de los niños han comprendido sus conceptos fundamentales y ya saben hablar, leer y escribir para distintos tipos de oyentes y para distintos propósitos. Para la consolidación de estos conocimientos y la adquisición de nuevas habilidades necesitan contar con una amplia gama de textos y contextos, aprender a decodificar palabras desconocidas, deletrear palabras difíciles. El modelo de lectura y escritura compartida y guiada es la estrategia de enseñanza más idónea.

Guided reading : teacher's workbook.

Es un módulo, de carácter interactivo, en el que se recomienda que no haya más de doce participantes, para que cada uno tenga la oportunidad de expresar sus pensamientos, preguntas e investigaciones en el aula. Lectura guiada es una técnica de instrucción y evaluación que apoya y fomenta el desarrollo de estrategias de lectura independiente. El grupo debe estar formado por cuatro o seis niños, cada uno de los cuales tiene una copia del libro a leer y su actividad debe de ser la de dar sentido de forma independiente al texto, con el apoyo de los demás miembros del grupo y del profesor. El apoyo del docente es breve, y su actitud es observar, afirmar y responder a las necesidades de los niños e invitarles a utilizar los recursos y estrategias de los que disponen.

Guided reading : course co-ordinator's book.

Es un módulo, de carácter interactivo, sobre 'lectura guiada' en el que se recomienda que no haya más de doce participantes, uno de los cuales es el responsable de la organización de las sesiones. Lectura guiada es una técnica de instrucción y evaluación que apoya y fomenta el desarrollo de estrategias de lectura independiente. El responsable del módulo propone las actividades que se realizan en las sesiones para las diferentes etapas en los primeros años de escolarización, los materiales y equipos que serán necesarios para apoyar cada período de sesiones,las sugerencias de textos de ficción y no ficción que los participantes apoyan para las actividades de lectura guiada, y por último,cómo llevar a cabo las sesiones de apoyo y las tareas y actividades.

Book bands for guided reading : organising key stage one texts for the literacy hour.

Ha sido pensado para ayudar a los profesores a revisar, organizar y completar en las escuelas, las existencias de materiales de lectura para la etapa uno (Key Stage uno). También, proporciona las bases para establecer los procedimientos de lectura guiada en la etapa de alfabetización infantil, y para indicar cómo la lectura guiada encaja dentro de la National Literacy Strategy Framework for Teaching (Estrategia Nacional de Alfabetización Marco para la Enseñanza). Se reunieron casi cuatro mil libros para los niños, que se han agrupado teniendo en cuenta la gradación de dificultad de los textos en diez bloques, desde los más sencillos para los primeros lectores a áquellos utilizados al final de la etapa uno (Key stage uno) para lectores con más fluidez.

A seven-year follow-up of men following a benign prostate biopsy

Objectives: To determine the incidence and clinical relevance of newly diagnosed cases of prostate cancer in a group of men who had an elevated PSA and benign prostate biopsy 7 years previously. Patients and Method: Patients under the age of 80 years with an elevated PSA who had had a benign prostate biopsy in the 12 months between March 1, 1994 and February 28, 1995 were studied. One hundred and sixty four patients with a mean age of 66.8 years (range 47-79 years) were identified. The mean PSA for this group was 10.3 ng/ml (range 4.1-81 ng/ml). One hundred and fifty nine of the 164 (97%) hospital records were available for review and all but 21 (12.8%) of the General Practitioners were contacted. Results: Eighteen (11%) of the original 164 patients were subsequently diagnosed with prostate cancer, 2 died from their disease. Conclusions: In a population where the follow-up of patients with a benign biopsy was arranged on clinical grounds alone, 11% of the study group were diagnosed with prostate cancer during a seven-year follow-up. Although some of these cancers appear to be slow growing, most of those diagnosed in the initial follow-up period were deemed to be clinically significant and a small proportion progressed rapidly to metastases. All patients who have an elevated PSA, but benign biopsy, should undergo a period of PSA monitoring until it is clear that their PSA is not rising. We propose an initial intensive monitoring period to avoid missing those with clinically aggressive disease. (C) 2003 Elsevier Science B.V. All rights reserved.

Molecular guided catalytic hydrogenation by micelle-hosted Pd nanoparticle in supercritical CO2

Homogeneous dispersion of microemulsion containing palladium nanoparticles in scCO(2) is, for the first time, observed via sapphire window reactor and these particles show an unusual reluctance for double bond hydrogenation of citral aldehyde at hydrophobic end rather than hydrophilic end (high regioselectivity) owing to the unique micelle environment in supercritical carbon dioxide that guide a head-on attack of the molecule.

Midpoint perturbation response in haptically-guided movements

This study investigates the human response to impulse perturbations at the midpoint of a haptically-guided straight-line point-to-point movement. Such perturbation response may be used as an assessment tool during robot-mediated neuro-rehabilitation therapy. Subjects show variety in their perturbation responses. Movements with a lower perturbation displacement exhibit high frequency oscillations, indicative of increased joint stiffness. Equally, movements with a high perturbation displacement exhibit lower frequency oscillations with higher amplitude and a longer settling time. Some subjects show unexpected transients during the perturbation impulse, which may be caused by complex joint interactions in the hand and arm.

Feasibility of guided CBT self-help for childhood anxiety disorders in primary care

Anxiety disorders in childhood are common, disabling and run a chronic course. Cognitive Behaviour Therapy (CBT) effective but is expensive and trained therapists are scarce. Guided self-help treatments may be a means of widening access to treatment. This study aimed to examine the feasibility of guided CBT self-help for childhood anxiety disorders in Primary Care, specifically in terms of therapist adherence, patient and therapist satisfaction and clinical gain. Participants were children aged 5-12 years referred to two Primary Child and Adolescent Mental Health Services (PCAMHSs) in Oxfordshire, UK, who met diagnostic criteria for a primary anxiety disorder. Of the 52 eligible children, 41 anxious children were assessed for anxiety severity and interference before and after receiving CBT self-help, delivered via the parent (total therapy time= 5 hours) by Primary Mental Health Workers (PMHWs). Therapy sessions were rated for treatment adherence and patients and PMHWs completed satisfaction questionnaires after treatment completion. Over 80% of therapy sessions were rated at a high level of treatment adherence. Parents and PMHWs reported high satisfaction with the treatment. 61% of the children assessed no longer met criteria for their primary anxiety disorder diagnosis following treatment, and 76% were rated as ‘much’/’very much’ improved on the Clinician’s Global Impression-Improvement scale. There were significant reductions on parent and child report measures of anxiety symptoms, interference, and depression. Preliminary exploration indicated that parental anxiety was associated with child treatment outcome. The findings suggest that guided CBT self-help represents a promising treatment for childhood anxiety in primary care.

Delays versus performance of visually guided systems

The paper presents an overview of dynamic systems with inherent delays in both feedforward and feedback paths and how the performance of such systems can be affected by such delays. The authors concentrate on visually guided systems, where the behaviour of the system is largely dependent on the results of the vision sensors, with particular reference to active robot heads (real-time gaze control). We show how the performance of such systems can deteriorate substantially with the presence of unknown and/or variable delays. Considered choice of system architecture, however, allows the performance of active vision systems to be optimised with respect to the delays present in the system.

Improvement of 3D protein models using multiple templates guided by single-template model quality assessment

Motivation: Modelling the 3D structures of proteins can often be enhanced if more than one fold template is used during the modelling process. However, in many cases, this may also result in poorer model quality for a given target or alignment method. There is a need for modelling protocols that can both consistently and significantly improve 3D models and provide an indication of when models might not benefit from the use of multiple target-template alignments. Here, we investigate the use of both global and local model quality prediction scores produced by ModFOLDclust2, to improve the selection of target-template alignments for the construction of multiple-template models. Additionally, we evaluate clustering the resulting population of multi- and single-template models for the improvement of our IntFOLD-TS tertiary structure prediction method. Results: We find that using accurate local model quality scores to guide alignment selection is the most consistent way to significantly improve models for each of the sequence to structure alignment methods tested. In addition, using accurate global model quality for re-ranking alignments, prior to selection, further improves the majority of multi-template modelling methods tested. Furthermore, subsequent clustering of the resulting population of multiple-template models significantly improves the quality of selected models compared with the previous version of our tertiary structure prediction method, IntFOLD-TS.

The treatment of child anxiety disorders via guided parent-delivered cognitive-behavioural therapy: a randomised controlled trial

Background Promising evidence has emerged of clinical gains using guided self-help cognitive-behavioural therapy (CBT) for child anxiety and by involving parents in treatment; however, the efficacy of guided parent-delivered CBT has not been systematically evaluated in UK primary and secondary settings. Aims To evaluate the efficacy of low-intensity guided parent-delivered CBT treatments for children with anxiety disorders. Method A total of 194 children presenting with a current anxiety disorder, whose primary carer did not meet criteria for a current anxiety disorder, were randomly allocated to full guided parent-delivered CBT (four face-to-face and four telephone sessions) or brief guided parent-delivered CBT (two face-to-face and two telephone sessions), or a wait-list control group (trial registration: ISRCTN92977593). Presence and severity of child primary anxiety disorder (Anxiety Disorders Interview Schedule for DSM-IV, child/parent versions), improvement in child presentation of anxiety (Clinical Global Impression-Improvement scale), and change in child anxiety symptoms (Spence Children’s Anxiety Scale, child/parent version and Child Anxiety Impact scale, parent version) were assessed at post-treatment and for those in the two active treatment groups, 6 months post-treatment. Results Full guided parent-delivered CBT produced superior diagnostic outcomes compared with wait-list at post-treatment, whereas brief guided parent-delivered CBT did not: at post-treatment, 25 (50%) of those in the full guided CBT group had recovered from their primary diagnosis, compared with 16 (25%) of those on the wait-list (relative risk (RR) 1.85, 95% CI 1.14-2.99); and in the brief guided CBT group, 18 participants (39%) had recovered from their primary diagnosis post-treatment (RR = 1.56, 95% CI 0.89-2.74). Level of therapist training and experience was unrelated to child outcome. Conclusions Full guided parent-delivered CBT is an effective and inexpensive first-line
