[press release] Penn Professor Shows How ‘Spontaneous’ Social Norms Emerge

Thinking this still does not shed any light on “wisdom of crowds” vs rumor mongering.  Consensus isn’t always a matter of truth finding.  Critical thinking skills are important!
Great insight, tho’.

From the 2 February 2015 Penn State press release by Katherine Unger Baillie

Fifteen years ago, the name “Aiden” was hardly on the radar of Americans with new babies. It ranked a lowly 324th on the Social Security Administration’s list of popular baby names. But less than a decade later, the name became a favorite, soaring into the top 20 for five years and counting.

While some may attribute its popularity to a “Sex in the City” character, a new study led by the University of Pennsylvania’s Damon Centola provides a scientific explanation for how social conventions – everything from acceptable baby names to standards of professional conduct – can emerge suddenly, seemingly out of nowhere, with no external forces driving their creation.

The research used an original Web-based experiment to test whether and how large populations come to consensus. The findings have implications for everything from understanding why different regions of the country have distinct words for the same product — soda versus pop, for example — to explaining how norms regarding civil rights gained widespread traction in the United States.

The paper, “The Spontaneous Emergence of Conventions,” will appear in the Early Edition of theProceedings of the National Academy of Sciences the week of Feb. 2.

“Our study explains how certain ideas and behaviors can gain a foothold and, all of a sudden, emerge as big winners,” Centola said. “It is a common misconception that this process depends upon some kind of leader, or centralized media source, to coordinate a population.  We show that it can depend on nothing more than the normal interactions of people in social networks.”

Centola is an associate professor in Penn’s Annenberg School for Communication and the School of Engineering and Applied Science and is director of the Network Dynamics Group at Penn. He partnered on the work with physicist Andrea Baronchelli, an assistant professor at City University London.

To understand how social norms arise, Centola and Baronchelli invented a Web-based game, which recruited participants from around the World Wide Web using online advertisements. In each round of the “Name Game,” participants were paired, shown a photograph of a human face and asked to give it a name. If both players provided the same name, they won a small amount of money. If they failed, they lost a small amount and saw their partner’s name suggestion. The game continued with new partners for as many as 40 rounds.

Though the basic structure of the game remained the same throughout the experiment, the researchers wanted to see whether changing the way that players interacted with one another would affect the ability of the group to come to consensus.

They began with a game of 24 players, each of whom was assigned a particular position within an online “social network.” The participants, however, weren’t aware of their position, didn’t know who they were playing with or even how many other players were in the game.

Centola and Baronchelli tested the effects of three different types of networks.

In the “geographical network” version, players interacted repeatedly with their four closest neighbors in a spatial neighborhood. In the “small world network” game, participants still played with only four other players, but the partners were chosen randomly from around the network. And in the “random mixing” version, players were not limited to four other partners, instead playing each new round with a new partner selected at random from all the participants.

As the games proceeded, the researchers observed clear patterns in people’s behavior that distinguished the different networks.

In the geographical and small world network games, participants easily coordinated with their neighbors, but they were not able to settle on one overall “winning” name for the population. Instead, a few competing names emerged as popular options: Sarah, Elena, Charlene and Julie all vying for dominance, for instance, with no global agreement.

Came across this article through an online professional health community.  It describes how the Internet is changing approaches to healthcare issues.  Current evidence shows Web sites can empower professional and lay alike through informational Web pages, social media, health record annotations and linkages for exploration and analysis. However, these applications can be built on to better serve the health care related needs of all.  The Web can be better” engineered for health research, clinical research, and clinical practice. In addition, it is desirable to support consumers who utilize the Web for gathering information about health and well-being and to elucidate approaches to providing social support to both patients and caregivers. Finally, there is the motivation to improve both the effectiveness and efficiency of health care.” The paper goes on to outline channelling further efforts in these areas.

Abstract

The transformative power of the Internet on all aspects of daily life, including health care, has been widely recognized both in the scientific literature and in public discourse. Viewed through the various lenses of diverse academic disciplines, these transformations reveal opportunities realized, the promise of future advances, and even potential problems created by the penetration of the World Wide Web for both individuals and for society at large. Discussions about the clinical and health research implications of the widespread adoption of information technologies, including the Internet, have been subsumed under the disciplinary label of Medicine 2.0. More recently, however, multi-disciplinary research has emerged that is focused on the achievement and promise of the Web itself, as it relates to healthcare issues. In this paper, we explore and interrogate the contributions of the burgeoning field of Web Science in relation to health maintenance, health care, and health policy. From this, we introduce Health Web Science as a subdiscipline of Web Science, distinct from but overlapping with Medicine 2.0. This paper builds on the presentations and subsequent interdisciplinary dialogue that developed among Web-oriented investigators present at the 2012 Medicine 2.0 Conference in Boston, Massachusetts.

Internet search data and unreported side effects of drugs

Public Health--Research & Library News

A very interesting use of crowdsourcing for medical research.

Using data drawn from queries entered into Google, Microsoft and Yahoo search engines, scientists at Microsoft, Stanford and Columbia University have for the first time been able to detect evidence of unreported prescription drug side effects before they were found by the Food and Drug Administration’s warning system.

Using automated software tools to examine queries by six million Internet users taken from Web search logs in 2010, the researchers looked for searches relating to an antidepressant, paroxetine, and a cholesterol lowering drug, pravastatin. They were able to find evidence that the combination of the two drugs caused high blood sugar.

The study, which was reported in the Journal of the American Medical Informatics Association [White, R.W. et al. Web-scale pharmacovigilance: listening to signals from the crowd. J Am Med Inform Assoc doi:10.1136/amiajnl-2012-001482] on Wednesday, is based on data-mining techniques similar to those…

John Adler who is a neurosurgeon at Stanford just launched Curēus, an open-source medical journal that leverages crowdsourcing to make scientific research more readily available to the general public. What do you think?

Based in Palo Alto, California, Curēus is the medical journal for a new generation of both doctors AND patients. Leveraging the power of an online, crowd-sourced community platform, Curēus promotes medical research by offering tools that better serve and highlight the people who create it, resulting in better research, faster publication and easier access for everyone.

We make it easier and faster to publish your work – it’s always free and you retain the copyright. What’s more, the Curēus platform is designed to provide a place for physicians to build their digital CV anchored with their posters and papers.

The Curēus site also has..

Currently, a relatively few number of papers online. The concept is good, here’s hoping this is not a flash in the pan, but the wave of the future.

Better medicine, brought to you by big data through new types of data analysis

 

A good overview of how improved data analysis and presentation is improving health care delivery.

I especially liked the slideshare presentation found below in Related Articles.
The 42 slides in Big data – a brief overview outlines what big data is, its sources and processes, how it is analyzed, current “players”,examples, market analysis, future, and opportunities.

From the 15 July 2012 blog post at Gigaom

Slowly but surely, health care is becoming a killer app for big data. Whether it’s Hadoop, machine learning, natural-language processing or some other technique, folks in the worlds of medicine and hospital administration understand that new types of data analysis are the key to helping them take their fields to the next level.

Here are some of the interesting use cases we’ve written about over the past year or so, and a few others I’ve just come across recently. If you have a cool one — or a suggestion for a new use of big data within the healthcare space — share it in the comments:

Genomics. This is the epitomic case for big data and health care. Genome sequencing isgetting cheaper by the day and produces mountains of data. Companies such asDNAnexusBina TechnologiesAppistry and NextBio want to make analyzing that data to discover cures for diseases faster, easier and cheaper than ever using lots cutting-edge algorithms and lots of cloud computing cores.
BI[definition of business intelligence] for doctors. Doctors and staff at Seattle Children’s Hospital are using Tableau to analyze and visualize terabytes of data dispersed across the institution’s servers and databases. Not only does visualizing the data help reduce medical errors and help the hospital plan trials but, as of this time last year, its focus on data had saved the hospital $3 million on supply chain costs….
..Semantic search. Imagine you’re a doctor trying to learn about a new patient or figure out who among your patients might benenfit from a new technique. But patient records have been scattered throughout departments, vary in format and, perhaps worst of all, all use the ontologies of the department that created the record. A startup called Apixio is trying to fix this by centralizing records in the cloud and applying semantic analysis to uncover everything doctors need, regardless who wrote it…
..Getting ahead of disease. It’s always good if you figure out how to diagnose diseases early without expensive tests, and that’s just what Seton Healthcare was able to dothanks to its big data efforts…
and more!
