Bibliographic metadata plays a key role in scientific litera- ture, not only to summarise and establish the facts of the publication record, but also to track citations between pub- lications and hence to establish the impact of individual ar- ticles within the literature. Commercial secondary publish- ers have typically taken on the role of rekeying, mining and analysing this huge corpus of linked data, but as the primary literature has moved to the world of the digital repository, this task is now undertaken by new services such as Citeseer, Citebase or Google Scholar. As institutional and subject- based repositories proliferate and Open Access mandates increase, more of the literature will become openly avail- able in well managed data islands containing a much greater amount of detailed bibliometric metadata in formats such as RDF. Through the use of efficient extraction and inference techniques, complex relations between data items can be es- tablished. In this paper we explain

The question of citation behavior has always intrigued scientists from various disciplines. While general citation patterns have been widely studied in the literature we develop the notion of citation projection graphs by investigating the citations among the publi- cations that a given paper cites. We investigate how patterns of citations vary between various scientific disciplines and how such patterns reflect the scientific impact of the paper. We find that id- iosyncratic citation patterns are characteristic for low impact pa- pers; while narrow, discipline-focused citation patterns are com- mon for medium impact papers. Our results show that crossing- community, or bridging citation patters are high risk and high re- ward since such patterns are characteristic for both low and high impact papers. Last, we observe that recently citation networks are trending toward more bridging and interdisciplinary forms.

“La universidad es un gran espejo en el que se reflejan los requerimientos y posibilidades de la sociedad”
“Absolutamente nada de lo relativo a la cultura puede resultarle indiferente a la universidad”
“La universidad es como un caleidoscopio que lleva a imaginar un mundo que queremos que sea cambiante”
“No somos la suma de facultades, sino que en la universidad todo está integrado”
“Esta universidad no es una quimera, todas las universidades aquí representadas son semilleros de conocimiento…”
“Si los jóvenes no contaran con la universidad, serían como un cuerpo sin cerebro”
“En nuestros países hay investigadores de primer nivel. Esto debería motivar a los gobiernos a apoyar la educación”
“Nuestra Universidad ya es sólo investigar o educar, es atender a la problemática global”
“Hay que atender a lo acuciante en lo económico, en lo ecológico, en lo social “
“El título de ‘Universidad’ sólo puede otorgarse a quienes lo merezcan por su calidad en docencia e investigación” -

Introduction
Meta-analysis is a statistical technique for amalgamating, summarising, and reviewing previous quantitative research. By using meta-analysis, a wide variety of questions can be investigated, as long as a reasonable body of primary research studies exist. Selected parts of the reported results of primary studies are entered into a database, and this "meta-data" is "meta-analyzed", in similar ways to working with other data – descriptively and then inferentially to test certain hypotheses.
Meta analysis can be used as a guide to answer the question 'does what we are doing make a difference to X?', even if 'X' has been measured using different instruments across a range of different people. Meta-analysis provides a systematic overview of quantitative research which has examined a particular question.
The appeal of meta analysis is that it in effect combines all the research on one topic into one large study with many participants. The danger is that in …

Eso, dicen, "es una cortina de humo" y acusa a Apple de "encerrar a consumidores y creadores".
Ayer Steve Jobs desgranó los seis motivos por los que su compañía rechaza que Flash funcione en sus aparatos móviles, como el iPhone. Flash es de la "era del PC no de los móviles", dijo Jobs. Flash es "de la época del ratón, no de las pantallas táctiles". Flash "no es abierto, como HTML, CSS y Javascript". Flash tampoco "es seguro ni estable y gasta más más batería". El jefe de Apple reconocía que como Flash era multiplataforma su compañía no "puede depender de otra". Por último, tras acusar nuevamene a Adobe de no hacer sus deberes, Jobs les sugería que se centraran en crear buenas herramientas basadas en HTML5 y se dejaran de criticar a Apple "por haber dejado atrás el pasado" -
El desplante de Jobs ha surtido efecto. Toda una industria ha clavado su atención en el potencial de HTML5.

UNA SOCIEDAD EN MOVILIDAD: NUEVAS FRONTERAS
La movilidad, la ubicuidad en la comunicación encarnan hoy múltiples dispositivos que han conquistado un lugar cada vez más decisivo en los usos sociales. Las aportaciones analíticas de los 14 especialistas que escriben en este dossier van mucho más allá de la consideración de la telefonía móvil e incluyen otros aspectos de la sociedad en movilidad que se basa en lo que algunos autores han llamado ya cuarta pantalla y que está provocando cambios radicales en distintos ámbitos de la vida humana.

In earlier blog postings on the best type of publication outlet for ICT4D research and on ICT4D research quality and impact, I surmised that there is value in publishing ICT4D research in specialist ICT4D journals. But I skirted round the issue of which ICT4D journal to publish in. Here, then, is an ICT4D journal “league table”:

Intelligent agents and the Semantic Web
Developing an intelligent Web
Daniel J Lewis, Technology Evangelist/Computer Scientist, OpenLink Software
Summary: The Semantic Web envisioned by Berners-Lee, Hendler, and Lassila in 2001 was a grandiose vision that involved the use of agents to book doctor appointments and to find the best driving routes with the least hassle. The envisaged system was built upon formal ontologies that had already achieved a large following of scientists and agent developers. Although they raised some important issues and put forward interesting connections between technologies, they missed one thing: the fact that the Web had turned into a web of documents. Therefore, a middle way needed to occur between the formalism of ontologies and the informalism of documents. This is known as Linked Data. Linked Data coupled with agent technology is an ideal way of dealing with Semantic Web data. This article provides an overview o

Nature of the rubric
The rubric for scoring academic skills is essentially qualitative and descriptive in nature and relies on criterion-referenced perspectives. It serves to appraise academic competencies such as the ability to critique, to produce scholarly work, to synthesize, and to apply newly acquired principles and concepts. It requires the use of criteria that best describe actual student products in a postsecondary setting. The criteria form the left-hand column of the two-way table format and the horizontal continuum contains headings indicating four increasing levels of performance towards competency mastery (Wiggins, 1998).
The use of the scale involves the acts of scoring, interpreting, and judging. (Forgette-Giroux, & Simon, 1998; Simon, & Forgette-Giroux, 2000). Scoring occurs when one identifies, within the scale, and for each criterion, the cell description that most closely matches the observed performance. The interpretation consists of locating the col…

This is a rubric for Collaborating. Students are using electronic tools for sharing, editing and uploading materials. The tools would include products like elluminate. The rubric looks at the appropriate use of the tool to facilitate the discussion. The rubric does not look at the content or understanding specifically. There are three major areas or aspects of use. These are preparation for the collaboration session, the use of collaboration and communication features.

Podcasting is a creative process involving several different components. A successful podcast must be planned and scripted. It requires care and preparation to record and construct. Constructing the cast requires high quality speech, care and effort. (This task does not include uploading or posting the casts to websites as often schools restrict this.)

Most rubrics consist of objectives, performance characteristics, and points or scores that indicate the degree to which the objectives were met. Rubrics should be introduced to the students at the very beginning of a project unit — either present the rubric to the class or collaborate with the students to structure the rubric. Rubrics allow students to understand the criteria for assessment before they start the project.

Rubrics provide an objective scale with which teachers evaluate student work. By establishing criteria and defining the qualities that should be evident in an assignment ahead of time, teachers help students know exactly what is expected and provide a tool for them to check their own work before submitting it. However, writing a good rubric involves being specific enough to make the assignment clear, while remaining general enough to permit a creative demonstration of learning.

A rubric is a scoring guide. It organizes criteria that describe what students need to complete for an assignment, and it measures the levels of proficiency of student work. Rubrics can be used in any content area. They are time consuming to create, but they allow students and parents to know exactly how a teacher will grade an assignment.
