This talk is about Categorical Logic, a branch of Category Theory, a newer subfield of Algebra, established in the late forties/early fifties by Eilenberg and MacLane. One of its most exciting applications is to theoretical computer science and I plan to discuss it, from a very personal perspective.

Dynamical Classes of Collective Attention in TwitterJanette Lehmann
Presentation at WWW, held in Lyon, April 2012.
Micro-blogging systems such as Twitter expose digital traces of social discourse with an unprecedented degree of resolution of individual behaviors. They offer an opportunity to investigate how a large-scale social system responds to exogenous or endogenous stimuli, and to disentangle the temporal, spatial and topical aspects of users’ activity. Here we focus on spikes of collective attention in Twitter, and specifically on peaks in the popularity of hashtags. Users employ hashtags as a form of social annotation, to define a shared context for a specific event, topic, or meme. We analyze a large-scale record of Twitter activity and find that the evolution of hashtag popularity over time defines discrete classes of hashtags. We link these dynamical classes to the events the hashtags represent and use text mining techniques to provide a semantic characterization of the hashtag classes. Moreover, we track the propagation of hashtags in the Twitter social network and find that epidemic spreading plays a minor role in hashtag popularity, which is mostly driven by exogenous factors.
This work was done in collaboration with Bruno Gonçalves, Jose J. Ramasco, and Ciro Cattuto.

Реклама призвана допомогти бібліотекам у вирішенні такій актуальній проблеми, як боротьба за увагу читача в сучасному світі. Ці методичні рекомендації висвітлюють рекламну діяльність бібліотек із різних боків: імідж та фірмовий стиль бібліотеки, етапи з яких має складатися власна рекламна кампанія, тощо. Значна частина брошури присвячена інноваційним формам роботи (бібліоніч, флешмоб, буктрейлер і т. ін.) і їх багатому рекламному та іміджевому потенціалу.

This document has been developed in close collaboration with experts, researchers and decision makers from more than 10 universities in order to provide a global perspective of the OER movement. Some of the more relevant trends identified in this study are exemplified by a broad range of initiatives, including: change in the organizational culture; flexible certification; new business models; middle term institutional strategy; incentives policy; use of non-commercial open source or self-develop platforms; focus on champions; decentralized – federated solutions; open standard, bibliometric criteria; search engine optimization; community building and peer-based collaboration; quality assurance; repurposing and licensing; and open publishing policies.
Los días 29 y 30 de mayo de 2010 tendrá lugar en Madrid un encuentro exclusivo para alumnos y antiguos alumnos de Esden.
Serán unas jornadas en las que los asistentes compartirán experiencias, además de asistir a las conferencias de personalidades de primer orden a nivel internacional.
Solving Cross-Domain Issues When Building Mashupsmehmetakin
When building Mashups, you need to consider different techniques to solve the cross-domain issue that is caused by the browser's Same Origin Policy. This session gives you an overview of possible techniques to overcome that problem. Starting with client-side solutions including JSONP, iframes and usage of the browser window object, server-side solutions like Apache’s mod_rewrite module or IBM’s Ajax Proxy as well as proprietary solutions including browser plug-ins, applets, signed scripts and Internet Explorer 8’s XDomainRequest are explored. The session will also cover cross-document messaging that was added in HTML 5 and give an overview of other cross-domain access proposals.
Los estudiantes Carol Maria Castro Silva y Claudia Patricia Gonzalez del grupo 212060_3 utilizaron diferentes formatos de papel para sus planos de acuerdo a la escala de sus diseños, con Carol usando formatos A4 para escalas 1:1 y 1:2, y Claudia usando el formato A3 para una escala de 2:1. Ambas estudiantes fueron tutoreadas por William Javier Cáceres.

La estadística se define como el estudio de datos cuantitativos de poblaciones y recursos para obtener inferencias basadas en probabilidades. Tiene su origen en Italia en el siglo 1700 y fue introducida en Inglaterra por ese entonces. A lo largo de la historia, se han utilizado datos estadísticos en la Biblia, Babilonia, Roma, Egipto y durante la Edad Media, especialmente bajo el mandato de Carlo Magno.
