Blast from the Past

Published by lisan on February 19, 2013 in Aging and Group Disparities.

Sunday’s Washington Post had an article on the divergent amounts spent on the elderly versus children. This was the theme of Sam Preston’s 1984 PAA Presidential address:

Feds spend $7 on elderly for every $1 on kids

The bulk of this article is based on a report from the Urban Institute.

Big Data Reveals Job Change

Task Specialization in U.S. Cities from 1880-2000
Guy Michaels, Ferdinand Rauch, Stephen J. Redding | NBER Working Paper 18715
January 2013

In this study, economists Guy Michaels, Ferdinand Rauch, and Stephen J. Redding analyze the verbs used to describe jobs in the U.S. Dictionary of Occupational Titles during a 120 year time period. They do this by geographic area, correlating their findings with the spread of telephone service and transportation networks. They discover “a systematic reallocation of employment over time towards interactive occupations, which involve tasks described by verbs that appear in thesaurus categories concerned with thought, communication and inter-social activity.”

An Exercise in Inefficiency: Sequestration/Threat of Sequestration

Published by lisan on January 28, 2013 in Funding News.

This is a collection of recent news articles on sequestration. For the most part, the articles concern NIH funding, although a few discuss all federal agencies. An earlier post links to a agency-by-agency cuts as well as UM-specific information.

Sequestration cuts no longer the ‘bad policy’ bogeyman for Congress
Jeremy Herb | The Hill
January 29, 2013
This news source focuses on Congress and the Federal government. It concludes “With the sequestration deadline a little over four weeks away, there appears to be little momentum in Congress or the White House to stop the cuts.”

Big Data: Google Flu

Published by lisan on January 10, 2013 in Data and Methodology.

Google Flu trends uses aggregated Google search data to estimate current flu activity in near real-time as compared to the results from confirmed cases via CDC epidemiologists. Bob Groves mentioned this site in his 50th Anniversary talk at PSC as an example of “wild” data, which can be merged with or compared to data collected via traditional methods. [See this post for more examples of wild data in social science research.]

Google Flu Trends | United States
This site allows one to see trends over time for the US, e.g., how this year, compares to the pattern in previous years. One can also get reports for specific states or metro areas. Note that this is the methodology used in an Economics dissertation on the under performance of Obama in selected states.

Google Flu Trends | World
This shows the same results, but based on the entire world. The first thing that is clear is the striking difference in flu trends between the Northern and Southern hemispheres (totally expected). One can select a specific country, included the United States, and examine the flu trends for that country.

Google Dengue Trends | World
This shows the results of an aggregated search for dengue fever. The first thing that is apparent is that dengue fever is not a search that folks in the US or England make or make often enough to register.

If you mentioned you had the flu on either Twitter or Facebook, your post got analyzed by Crimson Hexagon, a firm that does sentiment analysis.

Below are several articles that describe the methodology and usefulness of these big data techniques for disease surveillance purposes:

How to calculate life expectancy & why it matters

Published by lisan on January 7, 2013 in Methodology.

Social Security: It’s Worse Than You Think
Gary King and Samir Soneji | New York Times
January 5, 2013

This Opinion piece in the Sunday Times is a summary of a Demography article where the authors argue that the Social Security Administration underestimates how long Americans live. That means the trust fund will run out two years earlier than the government has predicted.

Here’s the link to the original article in Demography:

Statistical Security for Social Security
Samir Soneji and Gary King | Demography

[html] | [pdf]

This article has quite a few references to former PSC post-doc, John Wilmoth, who has also written on mortality projections and life expectancy.

Finally, for one more set of mortality estimates and methodology, see the Census Bureau’s National Population Projections web page. They have always projected higher life expectancy than the Social Security Administration, but their methodology is not the same as these authors:

Is the NIH Funding Model Efficient?

Published by lisan on December 10, 2012 in Data and Funding News.

Money and Science: To He that Hath
The Economist
December 8th, 2012
This analysis is based on the publication and funding record of the most highly cited biomedical papers and concluded that NIH may not support the best researchers. The link to the original article, in Nature, is provided below.

Research grants: Conform and be funded
Joshua M. Nicholson & John P.A. Ioannidis | Nature
December 5, 2012
Tag line: Too many US authors of the most innovative and influential papers in the life sciences do not receive NIH funding.

And, perhaps related to the above, NIH is considering anonymity for grant applicants:

And, be careful about unattributed text. Some federal agencies are using software to detect unattributed copying in research proposals. See below.

Why Don’t Parents Name Their Daughters Mary Anymore?

Published by lisan on December 6, 2012 in Culture, Values and Attitudes and Data.

Why Don’t Parents Name Their Daughters Mary Anymore?
Philip Cohen | the Atlantic
December 12, 2012

This article is by Philip Cohen, a professor at the University of Maryland. The Atlantic has picked up his blog, Family Inequality, where he posts short, but scholarly snippets.

This piece illustrates the decline in the name Mary via the Social Security Administration’s names database. He posits that this is due to a rise in the cultural value of individuality. Accordingly, people value names that are not common, perhaps even unique. A repercussion of this is that there were only 21,695 baby girls named Sophia (most popular name in 2011) whereas back in 1961, there were 47,655 girls name Mary.

Using Wild Data to Estimate International Migration

A previous post described several studies based on non-survey data, which inform demographic events. The following is another very creative example:

Wild Data: Expanding Social Science Resources

Published by lisan on November 15, 2012 in Data and Methodology.

Most researchers use survey data, but more and more researchers are using “wild” data, which is defined as data not produced for research purposes. In fact, several PSC researchers are part of an NSF/Census project, which explores the usefulness of “wild” data ranging from administrative data (Social Security death index, Social Security earnings data) to data harvested from the web.

Below are several examples of informative posts based on web-based data:

The New Secessionists: Plotting whitehouse.gov secession petitions
Neal Caren | Big Data blog
November 14, 2012

This post shows the origin of each of the signers of the wave of secession petitions on the whitehouse.gov website via a county-based map. It also includes an explanation of how this was done. Many of the posts on Caren’s Big Data blog are excellent tutorials for the fundamentals of quantitative text analysis for social scientists.

It is also useful to refer to the history of secession petitions in the US, provided here:

The second example of an application of wild data, comes from a post about ‘mapping racist tweets’ based on content on Twitter immediately after Obama was re-elected to his second term:

Note that a Harvard Ph.D. student used Google search data to study the under performance of Obama in 2008, which he atttributed to racial animus.

And finally, the Google NGram project has useful data for researchers. Here’s an article from the Economist where the “data is” vs “data are” question is examined. More pertinent to researchers might be the evolution of “Negro man” to “colored man” to “African-American man” in common usage.
