The combinatorics of interval-vector polytopes

An \emph{interval vector} is a $(0,1)$-vector in $\mathbb{R}^n$ for which all the 1's appear consecutively, and an \emph{interval-vector polytope} is the convex hull of a set of interval vectors in $\mathbb{R}^n$. We study three particular classes of interval vector polytopes which exhibit interesting geometric-combinatorial structures; e.g., one class has volumes equal to the Catalan numbers, whereas another class has face numbers given by the Pascal 3-triangle.Comment: 10 pages, 3 figure

Enseñanza y Tecnologías en el Nivel Superior: La “enseñanza aumentada” y el “docente global”

This paper examines the influence of information and communication technologies on Higher Education. This study aims to identify the impact of the technological evolution on distance education programs and on designing, implementing and evaluating them, which significantly impact on the students. Our hypothesis is that technological evolution – from web 1.0 to web 2.0 – has become techno-pedagogical evolution. This is expressed in the design of a new form of distance education for Higher Education; a modality which we called “Web Blended-Learning” (WB-Learning), that overcomes the “Blended-Learning” (B-Learning). As a result of the analysis, we argue that on the one side, the emergence of new technological environments has helped to enrich and deepen the teaching programs, phenomenon we call “Augmented Teaching”. On the other side, we maintain that those environments challenge the teacher and set a new role, which we call “The Global Teacher”.El propósito de este trabajo es señalar el impacto de la evolución tecnológica sobre las propuestas de enseñanza a distancia en el nivel superior, como así también el valor de la misma a la hora de diseñar, implementar y evaluar propuestas que impactan de manera significativa en sus destinatarios. La hipótesis que proponemos es que la evolución tecnológica ha devenido evolución tecno- pedagógica y se expresa en el diseño de una nueva organización de la enseñanza a distancia para el nivel superior, en una modalidad que hemos denominado Web Blended-Learning (WB-Learning) superadora de la denominada Blended-Learning (B-Learning). Como resultado del análisis sostendremos, por un lado, que el surgimiento de los nuevos entornos tecnológicos ha contribuido a enriquecer y profundizar la propuesta de enseñanza, fenómeno al que denominamos “enseñanza aumentada”; por el otro, dichos entornos desafían al docente y configuran un nuevo rol, al que denominamos “el docente global”

On Picard Groups of Perfectoid Covers of Toric Varieties

Let $X$ be a proper smooth toric variety over a perfectoid field of prime residue characteristic $p$. We study the perfectoid space $\mathcal{X}^{perf}$ which covers $X$ constructed by Scholze, showing that $\text{Pic}(\mathcal{X}^{perf})$ is canonically isomorphic to $\text{Pic}(X)[p^{-1}]$. We also compute the cohomology of line bundles on $\mathcal{X}^{perf}$ and establish analogs of Demazure and Batyrev-Borisov vanishing. This generalizes the first author's analogous results for "projectivoid space".Comment: 24 pages, comments are welcom

El método micro-textual como herramienta de análisis de foros en línea en contextos multiculturales

In this paper, we present the micro-textual method as an efficient analysis tool for the research that is being conducted about online teaching and multiculturalism in higher education, in Melton Centre for Jewish Education in the Hebrew University of Jerusalem. The aim of this paper is to show how the method allows to identify and characterize different types of dialogues in online forums, and to examine their evolution. The method consists of a toolbox of terms that was developed for the analysis of texts. The aim of the method is to contribute to the understanding of textual and intertextual discourse and its evolution in virtual courses, particularly in higher education. This method uses textual and contextual components for the understanding of texts. The ethno-cultural indicator is a main component and it is related to the participant’s membership in a religious or cultural group, and to issues related to its identity. Through the example that was chosen for this work, we propose to analyze questions related to the interrelationship among personal, professional and ethno-cultural indicators, as well as the role of the teacher in online higher education.En este trabajo presentaremos el método micro-textual, como una herramienta eficiente de análisis en la investigación que se está desarrollando sobre enseñanza en línea y multiculturalidad en la Educación Superior, en el Centro Melton de Educación Judía de la Universidad Hebrea de Jerusalem. El propósito del trabajo es mostrar de qué manera el método posibilita identificar y caracterizar diferentes tipos de diálogo en los foros en línea, y asimismo examinar su evolución.El método está constituido por una batería conceptual desarrollada para el análisis de textos y su objetivo es contribuir a la comprensión del discurso textual e intertextual y su evolución en cursos virtuales, en particular en la enseñanza superior. El mismo utiliza componentes textuales y contextuales para la comprensión de textos, siendo un componente central el indicador etno-cultural, vinculado a la pertenencia del participante a un grupo religioso o cultural, y a problemáticas relacionadas con su identidad. En la ejemplificación elegida para este trabajo, propondremos analizar cuestiones vinculadas a la interrelación entre los indicadores personales, profesionales y los etno-culturales; así como también al rol del docente en la educación superior en línea
