Het Amerikaanse Coalition for Networked Information (CNI) dat zich ten doel stelt "supporting the transformative promise of networked information technology for the advancement of scholarly communication and the enrichment of intellectual productivity" is een eigen YouTube-kanaal begonnen.
Op dit moment worden er nog maar een zestal video's aangeboden, waaronder David Rosenthal's discussie over de levensduur van digitale documenten (Duur: 1 uur en 20 min.), maar bij CNI zijn ze druk doende om ook opnames van eerdere bijeenkomsten beschikbaar te stellen.

Daniel Kahneman's TedTalk
Nobelprijswinnaar Daniel Kahneman(Princeton), die recentelijk nog in een externe evaluatiecommissie het onderzoek van het Tilburg Institute for Behavioral and Economics Research (TIBER) kwalificeerde als behorende tot de internationale top, in een TedTalk over
"how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy -- and our own self-awareness".

Quality and quantity
AlphaGalileo weet te melden dat de Deutsche Forschungsgemeinschaft (DFG) "Adopts Rules to Counter the Flood of Publications in Research" door vanaf 1 juli dit jaar het aantal opgevoerde publicaties bij subsidie-aanvragen en onderzoeksrapportages te beperken.
"With these regulations, the DFG wants to counteract the quantitative factors that have been increasing for years in terms of research publications. “Whether in performance-based funding allocations, postdoctoral qualifications, appointments, or reviewing funding proposals, increasing importance has been given to numerical indicators such as the H-index and the impact factor. The focus has not been on what research someone has done but rather how many papers have been published and where. This puts extreme pressure upon researchers to publish as much as possible and sometimes leads to cases of scientific misconduct in which incorrect statements are provided concerning the status of a publication. This is not in the interest of science,” stressed the DFG President."

Data, data everywhere
The Economist met een special issue over het managen van data, getiteld "Data, data everywhere".
"All these examples tell the same story: that the world contains an unimaginably vast amount of digital information which is getting ever vaster ever more rapidly. This makes it possible to do many things that previously could not be done: spot business trends, prevent diseases, combat crime and so on. Managed well, the data can be used to unlock new sources of economic value, provide fresh insights into science and hold governments to account".
"But they are also creating a host of new problems. Despite the abundance of tools to capture, process and share all this information—sensors, computers, mobile phones and the like—it already exceeds the available storage space. Moreover, ensuring data security and protecting privacy is becoming harder as the information multiplies and is shared ever more widely around the world".
Artikelen:
* Data deluge. Businesses, governments and society are only starting to tap its vast potential.
* All too much. Monstrous amounts of data.
*A different game. Information is transforming traditional businesses.
* Clicking for gold. How internet companies profit from data on the web.
The open society. Governments are letting in the light
* Show me. New ways of visualising data
* Needle in a haystack. The uses of information about information.
*New rules for big data. Regulators are having to rethink their brief
* Handling the cornucopia. The best way to deal with all that information is to use machines. But they need watching.

Nieuws en infographics
Nick Felton: Tracing Our Lives from PopTech on Vimeo.
Nicholas Felton, bekend van zijn persoonlijk jaarverslagen, waarin hij zijn doen en laten visualiseert, onderwierp samen met twee collega's de voorpagina van de New York Times voor een week, aan eenzelfde behandeling. De resultaten zijn te bekijken in "What We Are Saying".
Avoiding a Digital Dark Age
De American Scientist bericht over het belang van digitale conservering in "Avoiding a Digital Dark Age".
"Over the course of the 20th century and into the 21st, an increasing proportion of the information we create and use has been in the form of digital data. Many (most?) of us have given up writing messages on paper, instead adopting electronic formats, and have exchanged film-based photographic cameras for digital ones. Will those precious family photographs and letters—that is, email messages—created today survive for future generations, or will they suffer a sad fate like my backup floppy disks? It seems unavoidable that most of the data in our future will be digital, so it behooves us to understand how to manage and preserve digital data so we can avoid what some have called the “digital dark age.” This is the idea—or fear!—that if we cannot learn to explicitly save our digital data, we will lose that data and, with it, the record that future generations might use to remember and understand us."

PubMed
De Amerikaanse National Library of Medicine heeft een nieuwe handleiding voor PubMed gepubliceerd.
"PubMed is een via het internet gratis toegankelijke zoekrobot die de MEDLINE-databank met referenties naar medisch wetenschappelijke artikelen evenals de database met medische boeken van de NCBI doorzoekt. Vrijwel alle medisch belangrijke publicaties van de laatste tientallen jaren zijn daarin te vinden, over het algemeen met minimaal een samenvatting van het artikel, soms met een link naar het complete artikel", aldus Wikipedia.
Naast deze papieren hulp biedt PubMed in korte modules eveneens online trainingen aan.
