Opportunity to learn and widening gaps
Paraguay’s National System for the Evaluation of Educational Process (SNEPE) conducted census-based Grade-3 mathematics tests in 2015 and 2018, revealing a sharp overall drop in scores. We used these open datasets (n = 182,016) to investigate the source of this decline. We estimated two-level random-intercept models with standardised predictors, first separately for each cohort and then pooled across years with a random slope for year. In both co…
The Use of Digital Platforms for In-Person Teaching in Spanish Universities
INTRODUCCION. La forma en que se hace uso de las plataformas docentes es un elemento relevante en la satisfacción de la enseñanza presencial universitaria para el alumnado y el profesorado. El presente estudio trata de identificar patrones de comportamiento y factores relacionados con el uso de plataformas docentes en la enseñanza presencial en las universidades españolas. MÉTODO. Se ha diseñado un cuestionario dirigido al profesorado de universi…
Tierra
el objetivo del artículo fue estudiar las transformaciones del concepto “tierra” como objeto de la ciencia moderna en Occidente. Metodológicamente, el texto recurrió a la historia de las ideas con el fi n de identifi car el tránsito de sus representaciones singulares entre los siglos XVII y XIX. Para tal fi n, se seleccionaron y compararon como fuentes los análisis desarrollados por algunos fi lósofos e historiadores de la ciencia como Giorgio Ag…

Methodology to calculate the carbon footprint of household land use in the urban planning stage
Ciclovìa in Chicago
Ciclovìas create temporary spaces for physical activity by closing off streets to motorized traffic for short periods of time—typically a day at a time. In Chicago, these health promotion events are called “Open Streets” and follow a route through five diverse communities. We report findings for evaluation of 2008--2009 Open Streets events. The evaluation creates a framework for examining Ciclovìa outcomes and tracks attendance, participant chara…
Identification and Small Sample Estimation of Thurstone's Unrestricted Model for Paired Comparisons Data
The interpretation of a Thurstonian model for paired comparisons where the utilities' covariance matrix is unrestricted proved to be difficult due to the comparative nature of the data. We show that under a suitable constraint the utilities' correlation matrix can be estimated, yielding a readily interpretable solution. This set of identification constraints can recover any true utilities' covariance matrix, but it is not unique. Indeed, we show …
A Multidimensional Ideal Point Item Response Theory Model for Binary Data
We introduce a multidimensional item response theory (IRT) model for binary data based on a proximity response mechanism. Under the model, a respondent at the mode of the item response function (IRF) endorses the item with probability one. The mode of the IRF is the ideal point, or in the multidimensional case, an ideal hyperplane. The model yields closed form expressions for the cell probabilities. We estimate and test the goodness of fit of the…
