Nociones matemáticas adquiridas y audición diferenciada: edades 18-24 años

En este estudio, de orden cualitativo, se aplicó un cuestionario a 17 estudiantes con déficit auditivo, 18 a 24 años de edad, para obtener información sobre su comprensión de los números naturales, sus operaciones y sus relaciones básicas. Registrados en papel, los reactivos se presentaron en lengua escrita, con términos sencillos. Se prescindió de intérprete en la lengua de señas mexicana para identificar directamente posibles dificultades de comprensión de los conceptos matemáticos implicados; además, la aspiración de los participantes en el estudio al acceso a un bachillerato en línea impone su dominio de la lengua escrita. Los resultados indican el predominio de un razonamiento aditivo sobre el multiplicativo y, a lo más, una abstracción pseudoempírica en edades que en los normoyentes corresponden a las etapas del pensamiento formal. La escasa y deficiente producción en lengua escrita referida a los reactivos sugiere investigar el empleo del método de logogenia para su adquisición en conjunción con la del conocimiento matemático.

Imátgenes 16, 17 y 18

Hoy vengo a exponer una queja. Cada día, casi a todas horas, y, prácticamente en todo el mundo, soy maltratado. Y ese maltrato no es fruto del azar. Obedece patrones bien determinados de antemano por las voluntades de mis torturadores. Reconozco que a veces no es un maltrato auténtico y que incluso puede divertirme. Eso me mantiene en forma y me da un dinamismo que mi posición habitual no sugiere.

Códigos secretos: otra forma de aplicar las matrices en bachillerato (16-18)

Tras una breve introducción para hacer referencia a distintos tipos de códigos secretos, el articulo estudia con detalle, esquemáticamente y mediante ejemplos, los códigos matriciales. Se expone, además, una forma de automatizar dichos códigos en el aula, mediante un programa escrito en dBASE III Plus. La parte final consta de unas preguntas sobre sus posibilidades didácticas.

The EXODUS evacuation model applied to building evacuation scenarios

The purpose of this paper is to demonstrate the potential of the EXODUS evacuation model in building environments. The latest PC/workstation version of EXODUS is described and is also applied to a large hypothetical supermarket/restaurant complex measuring 50 m x 40 m. A range of scenarios is presented where population characteristics (such as size, individual travel speeds, and individual response times), and enclosure configuration characteristics (such as number of exits, size of exits, and opening times of exits) are varied. The results demonstrate a wide range of occupant behavior including overtaking, queuing, redirection, and conflict avoidance. Evacuation performance is measured by a number of model predicted parameters including individual exit flow rates, overall evacuation flow rates, total evacuation time, average evacuation time per occupant, average travel distance, and average wait time. The simulations highlight the profound impact that variations in individual travel speeds and occupant response times have in determining the overall evacuation performance.

Pädagogisches Wissen in Bildern. Zum Bildprogramm der französischen Ausgaben des 18. Jahrhunderts von Rousseaus "Émile"

Aus Anlass der 250. Wiederkehr der Erstauflage von Rousseaus Werk "Émile oder über die Erziehung" widmet sich der Text der Analyse seiner Illustrationen. Die französischen Ausgaben des 18. Jahrhunderts wurden mit Kupferstichen von unterschiedlichen Künstlern gestaltet. Dabei war das Bildprogramm der Erstausgabe des Jahres 1762 noch von Rousseau autorisiert, während die posthumen Auflagen dies nicht mehr waren und einen vollständigen Wechsel des Bildprogramms vollziehen. Diese beiden unterschiedlichen Bildprogramme werden analysiert und in den Kontext ihrer Druckgeschichte gestellt. Dabei zeigt sich, auf welche Art das pädagogische Hauptwerk Rousseaus bildlich illustriert wird. (DIPF/Orig.)

The influence of writing workshops on the content of plays is discussed.

D10.2 - Research Data Management Plan, version 1.0

This document is the first out of three iterations of the DMP that will be formally delivered during the project. Version 2 is due in month 24 and version 3 towards the end of the project. The DMP thus is not a fixed document; it evolves and gains more precision and substance during the lifespan of the project. In this first version we describe the planned research data sets related to the RAGE evaluation and validation activities, and the fifteen principles that will guide data management in RAGE. The former are described in the format of the EU data management template, and the latter in terms of their guiding principle, how we propose to implement them, and when they will be implemented. This document is thus first of all relevant to WP5 and WP8 members.

Characterisation of European Marine Sites: Mersey Estuary Special Protection Area. Occasional Publication of the Marine Biological Association 18

This report provides an overview of water and sediment quality within the Mersey Estuary European Marine Site (EMS) and examines evidence for their influence on bioloigcal condition. It has not been possible to determine adequately whether prevailing conditions in the Mersey impact on the interest features of the site as studies which address this issue have not been carried out. It is only possible to review the current level of knowledge regarding the biological and chemical status for the estuary, and extrapolate risks to the bird population. Often information relates to sites outside the EMS; where this is the case the authors have tried to appraise the general status of the estuary, based on best available knowledge.

Diversity of functional groups in the vegetation sandy seashore of the Grande, Anclitas and Caguamas Cays (Jardines de la Reina Archipelago, Cuba)

Sandy shores are known to be extreme ecosystems where the vegetation has evolved many morphological and physiological adaptations for its survival. With the aim of identify possible relationships between the vegetation´s functional diversity with abiotic factors and its corresponding quantification, we collected data on the abundance and richness of the sandy coast vegetation complex in Grande, Anclitas and Caguamas keys. Its flora is largely characterized by the dominance of hemicryptophytes and chamaephytes plants with nanophyllous leaves and displaying dispersal syndromes such as zoochory and anemochory. However, the functional groups´ richness, in the present study, varies from one key to another. Functional diversity is similar between the wet and dry seasons, and its spatial variation is influenced by the interplay of the set of abiotic factors herein studied.

Permanent draft genomes of four new coccolithoviruses: EhV-18, EhV-145, EhV-156 and EhV-164

Coccolithoviruses infect the marine coccolithophorid microalga Emiliania huxleyi. Here, we describe the genomes of four new coccolithoviruses isolated from UK coastal locations. Of particular interest, EhV-18 and EhV-145 encode serine palmitoyltransferase function via two distinct genes, whereas all other coccolithoviruses have SPT as a gene fusion of LCB1/LCB2 domains.
