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.

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.)

[In Backpages 18.1] The culture of new writing

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

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.

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.

Interleukin 18 promoter polymorphisms are not strongly associated with type 1 diabetes in a UK population

Interleukin 18 (IL18) is a proinflammatory cytokine whose levels are increased in the subclinical stage of insulin-dependent (type I) diabetes mellitus. Previous case-control studies have reported associations between IL18 -607C>A and -137G>C promoter polymorphisms and type I diabetes. We performed case-control and family-based association studies employing Pyrosequencing to assess if these IL18 polymorphisms are also associated with the development of type I diabetes in the Northern Ireland population. The chi2 analysis of genotype and allele frequencies for the IL18 polymorphisms in cases (n=433) vs controls (n=426) revealed no significant differences (P>0.05). Assessment of allele transmission distortion from informative parents to affected offspring also failed to confirm previously reported associations. Stratification of these analyses for age-at-onset and HLA-DR type did not reveal any significance associations. In conclusion, our data do not support the strong positive associations of IL18 promoter polymorphisms with type I diabetes reported in previous smaller studies.
