Do computer games lead to aggression?

We had a lunch discussion on that topic this week – of course, investigating the computer of a person running amok will reveal some (Counterstrike type) games due to his isolation. But such games are also on million of othercomputers who do not run riot and who get relaxed by playing games.
Nevertheless I read this week about the aggressive behaviour of teens who were not allowed to play the whole night World of Warcraft. So, there seems to be clear links Continue reading Do computer games lead to aggression? →

P≤0.0069 in election results

Too many “7” digits were found for candidate A in a study of the presidential election results.

This method is closely related to Benford’s Law. A highly significant (p ~ 0.0007) excess of vote counts for candidate K that start with the digit 7 is found (41 observed, 21.2–22 expected).

I have to admit that I heard for the first time of the Newcomb-Benford’s Law (NBL)…

Please, send always an ics file in the attachment

as it is rather time consuming to type in all appointments.

Appointments can be exported from outlook (win XP) abd ical (Mac OS X) just by drag and drop to your favorite mail program. It is just one click here on the attachment to import the date here (Lufthansa already knows that but you may use this hint in your company to get the inventor award). BTW The screenshot shows another neat idea of integrating dynamic Doodle feeds.

What is the best logistic model?

I have never heard a formal lecture answering this question even after many years in epidemiology. It should be parsimonious of course to avoid too many missings but seems largely a subjective approach to keep or drop a variable. It was therefore quite helpful to find now an online lecture that exemplifies a sound approach – check out unc.edu/courses/2006spring. I already used anova to compare models (at least since my move from SAS to R) while using AIC is something that I am adding now to my toolbox. Continue reading What is the best logistic model? →

Mac OS X running Sigmaplot

screenshotI haven’t found any replacement yet for Sigmaplot that is offered only as a native Windows application. Even buying a copy of Aabel didn’t bring me back the fast and intuitive plotting capabilities. Running Sigmaplot under Parallels is a pain using too much of the system ressources while Crossover failed to start up even after following these step-by-step instructions. Finally, with Crossover 8, it seems that a win98 bottle can run Sigmaplot 9!

Science flies

Still in the spirit of the last few posts, here comes something exciting: sciflies.org aims at

We look forward to receiving your application for funding of initial proof-of-concept STEM research projects in the range of $5,000 to $12,000. To participate in this unique online grassroots-funded opportunity, please complete the questionnaire about your project, including details of its possible outcome/impact and profiles of the researchers or research team.

but, sorry, I have to warn you – the website does NOT save your project – it took me 20 minutes to figure that out.

Mirror neurons and science careers

Spiegel online has an excellent report about mirror neurons, empathy, social background and research (taking up a theme in the ZEIT 2003)

“In unserer Kultur sind am erfolgreichsten die”, sagt Gruen, “die am meisten von ihren Gefühlen, von der Fähigkeit zum Mitgefühl abgeschnitten sind.”

Why just C11orf30?

I have already seen this data in Washington and even talked to one of the two first authors (pun!) at the airport – the first genomewide scan for atopic dermatitis is now being online at the nature genetics website. The overall effects are disppointing small – my quick plot gives the cumulative (sic!) negative log p values.

Clickstreams

An American team believes to describe science activity by web clicks on journal pages.

Over the course of 2007 and 2008, we collected nearly 1 billion user interactions recorded by the scholarly web portals of some of the most significant publishers, aggregators and institutional consortia.

with the conclusion Continue reading Clickstreams →

A better search engine for science?

New rumors say about Wolfram alpha

In this respect it is vastly smarter than (and different from) Google. Google simply retrieves documents based on keyword searches. Google doesn’t understand the question or the answer, and doesn’t compute answers based on models of various fields of human knowledge.
…
or those who are more scientifically inclined, Stephen showed me many interesting examples — for example, Wolfram Alpha was able to solve novel numeric sequencing problems, calculus problems, and could answer questions about the human genome too.

I have applied for a test account as I am interested in methods how to deal with genomic and all the other pentabyte of data — we urgently need a paradigm shift as single genome prices will go down to 1000 €. Continue reading A better search engine for science? →
