Topological characterization of the small cardinal ii

summary:We show that the small cardinal number i = \min \{\vert \Cal A \vert : \Cal A is a maximal independent family\} has the following topological characterization: $i = \min \{\kappa \leq c: \{0,1\}^{\kappa}$ has a dense irresolvable countable subspace\}, where $\{0,1\}^{\kappa}$ denotes the Cantor cube of weight $\kappa$. As a consequence of this result, we have that the Cantor cube of weight $c$ has a dense countable submaximal subspace, if we assume (ZFC plus $i=c$), or if we work in the Bell-Kunen model, where $i = {\aleph_{1}}$ and $c = {\aleph_{\omega_1}}$

Digital Competence Framework for Educators «DigCompEdu»: Translation and adaptation of «DigCompEdu Check-In» questionnaire

La tecnología, como ingrediente fundamental para el avance de la Sociedad del Conocimiento, ha asumido un papel fundamental en el entorno educativo. En esta línea, diferentes instituciones y estudios científicos respaldan la importancia de la competencia digital docente dentro de los nuevos contextos de alfabetización. Este artículo persigue brindar un análisis objetivo y riguroso del concepto, estudiando el principal marco europeo de competencia digital docente «DigCompEdu». Además, también se presenta la traducción y adaptación al español del cuestionario «DigCompEdu Check-In». Todo ello puede resultar de interés para vertebrar y evaluar planes formativos personalizados y para la mejora del nivel de competencia digital del profesorado. Así mismo, se propone abrir diferentes líneas de investigación relacionadas con las necesidades formativas en TIC, avaladas por herramientas fiables y válidas de evaluación competencialTechnology, as a fundamental ingredient for the advancement of the Knowledge Society, has assumed a fundamental role in the educational environment. At the same time, different institutions and scientific studies support the importance of digital teaching competence in new literacy contexts. This article, provide an objective and rigorous analysis of the concept, studying the Digital Competence Framework for Educators «DigCompEdu». In addition, it is presented the Spanish translation and adaptation of the «DigCompEdu Check-In» questionnaire. All of this may be of interest to support and evaluate personalized training plans and to improve the level of digital competence of educators. Likewise, it is proposed to open different lines of research related to training needs in ICT, backed by reliable and valid tools for competence assessment

Trends in ischemic heart disease and stroke death ratios in brazilian women and men

OBJECTIVE: Cardiovascular diseases are the main cause of death in women and men in Brazil, but the trends for the death ratios for ischemic heart disease and stroke in women and men remain unknown. METHOD: In this study, the trends for the death ratios among women and men who were over 30 years of age were analyzed from 1980 to 2005. Data were collected for both the Brazilian population and the metropolitan area of São Paulo. Estimates of the population size and data for mortality were then obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. The risk for death was adjusted using a direct method. RESULTS: Death rates due to cardiovascular disease, ischemic heart disease, and stroke have declined in both Brazil and the metropolitan region of São Paulo. A linear regression analysis revealed a similar trend for ischemic heart disease and demonstrated a male/female ratio of 1.653 ± 0.001 (r=0.228; p=0.262) in Brazil and 1.763 ± 0.008 (r=0.863;
