Rhode Island Pension System Collapsing
According to Walter Russell Mead of The American Interest:
Rhode Island State Capital Building, Providence, RI
I wonder if Rhode Island can qualify for a Federal bailout...
Source: Mead, W R (2011, September 5), Rhode Island Pension System Collapsing, The American Interest.
Rhode Island is one of the bluest states in the country, and one where public sector unions have long worked with sympathetic politicians to create a true blue system of well paid public employees retiring comfortably on generous pensions with cost of living raises automatically thrown in.... The only problem is that the state could never afford the beautiful utopia it was crafting...Read More

Visualize This
According to the publisher:
Data doesn't decrease; it is ever-increasing and can be overwhelming to organize in a way that makes sense to its intended audience. Wouldn't it be wonderful if we could actually visualize data in such a way that we could maximize its potential and tell a story in a clear, concise manner? Thanks to the creative genius of Nathan Yau, we can. With this full-color book, data visualization guru and author Nathan Yau uses step-by-step tutorials to show you how to visualize and tell stories with data. He explains how to gather, parse, and format data and then design high quality graphics that help you explore and present patterns, outliers, and relationships.Follow the links below to learn more.
- Presents a unique approach to visualizing and telling stories with data, from a data visualization expert and the creator of flowingdata.com, Nathan Yau
- Offers step-by-step tutorials and practical design tips for creating statistical graphics, geographical maps, and information design to find meaning in the numbers
- Details tools that can be used to visualize data-native graphics for the Web, such as ActionScript, Flash libraries, PHP, and JavaScript and tools to design graphics for print, such as R and Illustrator

US Employment to Population Ratio Continues Dive
According to the Bureau of Labor Statistics (BLS), the US employment to population ratio* for August 2011 declined to 58.5%, down from 58.6% for July 2011, and down from 58.8% a year ago. The US employment to population ratio has been trending downwards since 2000.
Many economists believe that reporting the number employed as a percentage of the civilian population provides a more accurate description of the current state of employment than conjecturing the number of "unemployed" in a population. The US employment to population ratio reached an historical peak of 64.4% on an annual basis in 2000.
*The BLS defines employment and population (civilian noninstitutional) as follows:

The US employment to population ratio reached an historical peak of 64.4% on an annual basis in 2000.
*The BLS defines employment and population (civilian noninstitutional) as follows:
Employment consists of all persons who, during the reference week (the calendar week including the twelfth day of the month), (a) did any work at all (at least 1 hour) as paid employees, worked in their own business or profession or on their own farm, or worked 15 hours or more as unpaid workers in an enterprise operated by a member of the family, or (b) were not working but had jobs or businesses from which they were temporarily absent because of vacation, illness, bad weather, childcare problems, maternity or paternity leave, labor-management dispute, job training, or other family or personal reasons, whether or not they were paid for the time off or were seeking other jobs.... The civilian noninstitutional population consists of persons 16 years of age and older residing in the 50 States and the District of Columbia who are not inmates of institutions (for example, penal and mental facilities and homes for the aged) and who are not on active duty in the Armed Forces.Source: Bureau of Labor Statistics

Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering. In the finance course, students would learn the exponential function, use formulas in spreadsheets and study the budgets of people, companies and governments. In the data course, students would gather their own data sets and learn how, in fields as diverse as sports and medicine, larger samples give better estimates of averages. In the basic engineering course, students would learn the workings of engines, sound waves, TV signals and computers. Science and math were originally discovered together, and they are best learned together now.Mathematics is at once, symbolic, real, and conceptual for some -- I tend to agree. Dr Garfunkel is the executive director of the Consortium for Mathematics and its Applications (COMAP). Follow the link below to learn more about COMAP's activities.
