The World of Multi-Mouse

Computers have proved a boon to education, but cash-strapped schools struggle to provide PCs. In this presentation, we address the question of how to get the same benefits of active participation and personal feedback that a computer provides at a cost of just a dollar per child per year. The answer is an “Interpersonal Computer,” in our case, consisting of a PC, a projector, and a mouse for each child participating in the activity.

In this presentation, we show how we can teach math and language by using a personal and a collaborative approach, and analyze the value of games.

E-CLOUDSS: Building e-Government Clouds Using Distributed Semantic Services
Cloud computing is facilitating unlimited access to the computing and storage resources needed to build applications. The underlying infrastructure manages such resources transparently, without demanding the application manage or reserve more resources than those it really requires. Therefore, database management systems have exploded into cloud services that must be tuned and composed for efficiently and cost-effectively managing, querying, and exploiting huge data sets.

In this talk, we address a querying approach that consists of composing services that provide data and data management functions (aggregation, storage, refreshment). We discuss how query processing is tuned with respect to the cost of accessing data and services, the cost of using cloud resources for executing the query, and the mashing up of results according to quality dimensions of completeness, data provenance, and data freshness. We also examine how this approach has provided solutions for e-government applications that integrate services from different countries.


Genoveva Vargas-Solar and Miguel Nussbaum

Miguel Nussbaum is full professor for Computer Science at the School of Engineering of the Universidad Católica de Chile. He is working since 1995 in how to transform the classroom experience with the support of Technology. He started using the Game Boy of Nintendo to introduce 1:1 and games in the classroom. In 2001 he began working with wirelessly interconnected Pocket PCs to perform small group collaborative learning, and in 2007 he in introduced the One Mouse per Child where 50 kids share one screen using an interpersonal Computer. He has worked with the support of Microsoft, HP, INTEL, Plan Ceibal (Uruguay), UNESCO and the IADB, among others, in schools in Argentina, Chile, Brazil, Guatemala, India, England, USA and Uruguay. He has 65 publications in journals of the ISI catalog with around 1400 citations in Google Scholar, obtained the best paper conference award at the Computer Supported Collaborative Learning conference in 2009, a paper of 2004 was the most cited paper of Computers and Education in 2009 in the time window 2004-2009, and won in 2011 the prize for Innovation in Education in Chile.

Genoveva Vargas-Solar is a senior researcher at both the Data and Knowledge Management Group at Universidad de las Américas Puebla and the French Council of Scientific Research (CNRS). She is a member of the HADAS group of the Informatics Laboratory of Grenoble, France, and the deputy director of the Franco-Mexican Laboratory of Informatics and Automatic Control. Genoveva’s academic background and research interests span two distinct fields: computer science, where she is focused on distributed and heterogeneous databases, query processing and optimization, and cost-based data management in cloud- and service-based database systems; and literature, where her concerns center on the literature of the Middle Ages and on mythology, particularly criticism and analysis of different myths of origins. Genoveva has coordinated several research projects in Europe and Latin America that were financed by governments and industrial partners. She actively promotes cooperation in computer science between Latin America and Europe, particularly between France and Mexico. She has a PhD in computer science from Joseph Fourier University and a PhD in literature from Stendhal University.
