Thomas Alva Edison got a patent for “electric-lamp” on January 27, 1880.

According to the Our Documents site:

In 1878 the creation of a practical long-burning electric light had eluded scientists for decades. With dreams of lighting up entire cites, Edison lined up financial backing, assembled a group of brilliant scientists and technicians, and applied his genius to the challenge of creating an effective and affordable electric lamp. With unflagging determination, Edison and his team tried out thousands of theories, convinced that every failure brought them one step closer to success. On January 27, 1880, Edison received the historic patent embodying the principles of his incandescent lamp that paved the way for the universal domestic use of electric light.

Our Documents grew out of the National Archives list of 100 milestone documents important to American history — Edison’s patent application was voted one of the top 100.  Our Documents is now a joint exercise combining the efforts of the National Archives, National History Day, and USA Freedom Corps.

Reading for government classes: Obama’s shift in governing philosophy

January 28, 2009

No, Obama didn’t change his mind.  He’s changing the way government does business — putting government on a more solidly-based, business-like model for performance, according to at least one observer.  That’s the shift discussed.

And it’s about time, I say.

Max Stier’s commentary on the Fed Page of the Washington Post quickly lays out the case that Obama’s making big changes.  Copy it for students in your government classes (or history classes, if you’re studying the presidency in any depth).  Stier wrote:

There are some fundamental reasons why our federal government’s operational health has been allowed to steadily deteriorate. It’s hard to change what you don’t measure, and our government operates in an environment with very few meaningful and useful measurements for performance. Perhaps more significantly, it is run by short-term political leadership that has little incentive to focus on long-term issues.

A typical presidential appointee stays in government for roughly two years and is rewarded for crisis management and scoring policy wins. These individuals are highly unlikely to spend significant energy on management issues, when the benefits of such an investment won’t be seen until after they are long gone.

(According to the Post, “Max Stier is president and CEO of Partnership for Public Service, a group that seeks to revitalize the federal government.”  I don’t know of him otherwise.)

Political appointees can be good, but too many have not been over the past 25 years.  A bad enough political appointee can frustrate even the most adept, dedicated-to-the-people’s-business career federal service employees, and frustrate the law and good management of agencies.

Let’s wish them all good luck.

Potential questions to follow-up this article in discussions:

  • Constitution: Under the Constitution, who specifically is charged with managing the federal agencies, the “federal bureaucracy?  What is that charge, in the Constitution?
  • Constitution, politics: What is the role of Congress in managing the federal bureaucracy?
  • Evaluating information sources: Do some research on the internet.  Is Max Stier a credible source of information on managing federal agencies?  Why, or why not?  Who provides an opposing view to Stier’s?  Are they credible?  Why or why not?
  • Evaluating information sources: Is the Fed Page of the Washington Post a good source of information about the federal bureaucracy?  (Students may want to investigate columnists and features at this site; the Fed Page was started as a one-page feature of the newspaper in the early 1980s, covering for the public issues that tended to slip through the cracks of other news coverage, but which were very important to the vast army of federal employees and federal policy wonks in Washington.)  What other sources might be expected?  What other sources are there?  (Federal News Radio is another site that focuses on the functions of the federal agencies — Mike Causey started out writing the column on the bureaucracy in the Washington Post; this is an AM radio station dedicated to covering federal functions in the federal city.  Other sources should include National Journal, and Congressional Quarterly, especially if you have those publications in your school library).
  • History, maybe a compare and contrast question: How has the federal bureaucracy changed over time?  Compare the size, scope and people employed by the federal government under the administrations of George Washington, Andrew Jackson, Ulysses Grant, James Garfield, William McKinley, Dwight Eisenhower, and Bill Clinton.  What trends become clear?  What major changes have occurred (civil service protection, for example)?
  • Analysis: How does the transition process from one president to the next affect federal employees and the operation of government?
  • Analysis: How does the transition of President Barack Obama compare with past transitions — especially that of President Franklin Roosevelt, who also faced a tough economic crisis, or Ronald Reagan, whose transition signalled a major shift in government emphasis and operation?

What other questions did your students find in this article?  Comments are open.

Go get the lesson plans on presidential inaugurations NOW!

January 14, 2009

One more time, I gotta say that the lesson plans from the Bill of Rights Institute on inauguration is top notch.  I’ve shared it around our department, and several people are downloading it, planning to put the stuff to use.  It’s a good, solid lesson plan, it looks like something that will engage students nicely, and it’s on a topic that could not possibly be more timely.

But the free download goes away tonight!  Go get the thing NOW!

The Bill of Rights Institute includes these lesson plans as a no-cost download with Being an American: Exploring the Ideals that Unite Us, Second Edition.  That book is cheap, too — just $19.95 — so you can pay a bit, and still get this great lesson plan, plus a whole bunch of other good stuff.

But I’m an even bigger cheapskate, and I want this stuff to be ready to use on January 21, when our kids start the next semester.  The hours are ticking away.


“I swear (or affirm)”: Ready for the inauguration?

January 14, 2009

Here’s a map that should be more viewed in America, but a map which has been much overlooked in the post-election euphoria, or post-election gloom.  It’s the map of electoral college results, still showing Republicans in a Soviet/Maoist red, and Democrats in blue:

Electoral College results from the 2008 presidential election - American Presidency Project

Electoral College results from the 2008 presidential election - American Presidency Project

Note especially the blue dot in Nebraska, around Omaha.  Nebraska splits its electoral college votes, giving each congressional district’s vote to the elector for the candidate who actually won in that district.  Obama won Omaha’s district; Nebraska is officially a red and blue state.  Maine also allows a split in electors, but this year did not see a split among the electorate.

America is not so red as some claim, even in the electoral college.  More states are surrounded by blue states than surrounded by red states.

Perhaps it’s time to find other ways to color these maps, so that we cannot so easily speak of a red state/blue state split that does not reflect politics, economics, or much of anything else in America.

Dallas students are out on inauguration day.  We can hope our government and history students will glue themselves to the television to watch the ceremony, but we know better than to expect it.

Will you discuss the inauguration in your classes, whatever the subject?  Here are some sources you could use:

Want to poison Boise? Apply within

December 23, 2008

Ada County, Idaho, is home to the state capital, Boise.

As with most county governments in the U.S., a lot of work is delegated to groups that are governed or advised by citizen boards.  Volunteers make up these boards.  In many municipalities, it’s difficult to recruit good citizens to do the work.

Perhaps Ada County is having difficulty getting volunteers to worry about mosquito abatement. Maybe that’s why the advertisement at the city’s unofficial “City Smart”  website urges unnecessary DDT poisoning of the town.

Tell Ada County What to Do

Feeling disenfranchised? Not happy with how the elections turned out? Well, there is still a way for you to impact the body politic in Ada County—the County Board of Commissioners is calling for volunteers to serve as advisors on a number of boards.

The County Commissioners, Paul Woods, Rick Yzaguirre, and Fred Tilman, made the appeal for volunteer advisors in the most recent edition of Ada County’s monthly newsletter.

“The county has numerous volunteer boards and advisory committees that help the Ada County Board of Commissioners in policy development and general operations in areas ranging from housing, planning and zoning, social work and recreation. The unpaid volunteer positions give citizens a unique, insider look at county government while they roll up their sleeves to help their local community. While each board has its own bylaws and varying terms of service, interested parties are always encouraged to apply for a position on any volunteer board,” the county said.

The county went on to describe eight examples of boards that rely on volunteer participation, I’ve profiles the three coolest boards here.

Historic Preservation Council—Are you one of those folks that loves to see historical photos from Ada County’s storied past? Would you love to help identify sites of historical significance or help with education efforts? When then consider helping out with the Ada County Historic Preservation Council where, according to the county, “members must demonstrate an interest, competence, or knowledge in history or historic preservation” and can have a positive effect on how the county coordinates its preservation activities.

Mosquito Abatement Advisory Board—I’m a huge advocate for bringing back DDT (dichloro-diphenyl-trichloroethane) that insecticide extraordinaire which got a bad rap in the 1960’s when it was panned in Rachel Carson’s inaccurate book, Silent Spring. Turns out that DDT is safe for humans and Silent Spring, “contains certain statements at variance with the facts as we now understand them”, as Cecil Adams so eloquently put it in his The Straight Dope column from December 13, 2002. If you feel like I do about slaughtering mosquitoes and ending West Nile Virus in Idaho, then consider volunteering for the Ada County Mosquito Abatement Advisory Board wherein you can meet to discuss our collective war on these blood-sucking bugs. If you are a mosquito-lover who thinks bugs are people too, I would not recommend this board for you. [emphasis added]

Board of Community Guardians—Finally, if you have a heart for the disabled or the mentally ill, you might be the right sort of volunteer for this important board. According to the county, “The Board of Community Guardians manages the Community Guardian Program, which assists individuals who cannot make decisions for themselves because of mental and/or physical impairments or disabilities. These individuals, who are either legally incapacitated or destitute with no financial security or family support., can be determined a ward of the county, and court-appointed volunteers oversee those wards.

If you are interested in volunteering for any of these advisory boards contact:

Board of Ada County Commission office

200 W. Front St., Third Floor, Boise.

Even the vaunted Cecil Adams writes a clunker from time to time, and his agreement with the wholly unsupportable claim that Rachel Carson was wrong is one of those clunkers (but his description of Lyndon Larouche will make you smile).  The facts differ from the claim in this ad:

  1. DDT’s “bad rap” was well deserved.  In the past three years dozens of news articles matched the science journals commemorating the recovery of bald eagles, brown pelicans, osprey and pergrine falcons — recoveries made possible by ending the use of DDT in the wild.  DDT kills entire ecosystems, starting with the predators at the top.  It’s dangerous stuff.
  2. Rachel Carson’s book, Silent Spring, pioneered the use of good, hard scientific data in popular writing.  In its 53 pages of footnotes to scientific studies, science journals and correspondence, critics have been unable to find inaccuracies.  Especially on the issue of DDT’s effects on wildlife, more than a thousand follow-up studies vindicated Carson.  I have not found a contrary study, not one.
  3. DDT is NOT the pesticide of choice for West Nile, in any case.  It’s almost like arguing that DDT is the pharmaceutical of choice to use against malaria — confusing the pesticides used to kill insects with the pharmaceuticals used to treat disease in humans.  DDT is unsuitable for outdoor use, illegal for outdoor use under the 1958 Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) and its subsequent amendments because it is “uncontrollable.”  DDT kills non-target species, often better than it kills target species. For mosquito abatement, DDT kills mosquito predators much more effectively than it kills mosquitoes. Plus, it sticks around for years, and it bioaccumulates up food chains, multiplying poison doses to predators, sometimes millions of times.
    West Nile mosquitoes can be effectively treated as larva, if their water homes are known; but DDT is particularly ill-suited for use in water. DDT works best when its spread can be confined indoors, which is where malaria-carrying mosquitoes usually bite. West Nile carriers live and bite outdoors.

I hope Ada County gets volunteers for the mosquito abatement board who know a little bit more about DDT, or who are open to listening to the mosquito abatement experts.


Killer county budget: “People will die”

November 27, 2008

How bad is our economic mess?

Ask county officials in Hamilton County, Kentucky (across the Ohio River from Cincinnati, Ohio).  According to Cincinnati.com, the website for the Cincinnati Enquirer:

County Administrator Patrick Thompson said Monday that the county may have to slash another $2.3 million from its already bare-bones budget proposed for 2009 because of tumbling sales tax collections and reduced funding from the state.

That means that the county will have to find more cuts on top of the more than $40 million it’s already cut from departmental requests.

The news comes as the county sheriff and other public safety officials say even the current recommendations will devastate their ability to do their jobs.

“It’s downright dangerous,” said Michael Snowden, director of Hamilton County’s Emergency Management Agency. “People will die. It’s as simple as that.”

He was referring to a recommendation to withdraw funding for the Greater Cincinnati Hazmat team, which responds to hazardous material spills.

The budget for 2009 has already been cut $31 million below the budget for 2008, to $241 million total.  Recommendations are already in place to lay off 500 workers.

What to do?

Project lower sales tax revenues.  Already done.

The county previously predicted $65 million, or a 0 percent growth, in sales tax receipts next year. Sales tax revenue typically accounts for about 25 percent of the county’s general fund budget. But because of the credit crunch and bailout fallout, all of which just came to a head in the past few months, spending has plummeted and the holiday shopping picture looks bleak. Thompson asked the board to revise that number to $63.9 million, a decrease of $1.1 million.

Maybe the state government can help out?

He also recommended reducing the amount of local money the county would receive from the state by 5 percent, or $1.2 million, to about $22.8 million because the state is in a similarly tough budget situation and likely won’t be able to fund the county adequately.

At least make sure that the public safety offices get funded.

Hamilton County Sheriff Simon Leis said the cuts will have a “dramatic impact” impact on his department. “In my career in law enforcement, this is the worst I’ve ever seen,” he said after the meeting about the budget situation. “We’ve got major problems.”

He said he may decide to cease providing security at the county buildings rather than take deputies off the road. If the county closes the Queensgate jail, 84 corrections officers and 25 support personnel would lose their jobs and 450 inmates would be released, said Leis. Because the county’s main jail has long been out of room, the Queensgate jail, meant for only low-level inmates, now also houses some of the more serious offenders, he said. Inmate charges include burglary, robbery and drug abuse.

“We do have violent offenders down there,” Leis said. “They’re not choir boys.”

The county says it can’t afford to staff or maintain the aging jail, which it leases from a corrections company.

By law, the Hamilton County, Ohio, budget needs to be locked in by January 1, 20 days prior to the inauguration of the new president. No one is talking about bail-outs for state and local governments, yet.

What would you do?


What should our representatives do?

November 24, 2008

John Florez, writing in Utah’s Deseret News:

It would be even more refreshing to have elected leaders openly declare conflicts of interest without having to be caught or hounded into doing so. Even better would be if they quickly recused themselves where conflicts exist — just because it’s the right thing to do.

It is encouraging to see much of the talk before the state pre-legislative -session talk has included ethics reform and enforcement. That government officials know the public is watching them closely is a gentle and persistent reminder that ethics isn’t going away once the election ended.

Keeping the people’s trust is vital, and that means keeping one’s word. It has been amazing to see the way the administration and Legislature can work together in rapid fashion when they want to accomplish things that a majority of the voters did not want, i.e. soccer stadiums, foreign nuclear waste, vouchers, school district splits, to name a few. If they can do it so quickly for the things we don’t want, they most certainly can work quickly together for the things we do want.


Dear President-elect Obama

November 24, 2008

Good execution of a lesson plan here, at one of my favorite blogs, The Living Classroom — with a lot of possibilities for follow-up.

A citizens plea to President-elect Obama

A citizen's plea to President-elect Obama

This may be the only elementary level classroom in the nation with its own lobbyist.

Never underestimate the power of students united to do good works.

In the Boy Scouts’ merit badge series on citizenship, Scouts are required to write letters to public officials.  This is a good exercise.  Not all students get the full value, but on the chance that answers actually come to the letters, this is a good classroom activity.

Hmmm.  I should use it more.


Obama went to the White House, and all you got was . . .

November 17, 2008

Oh, wait.  He’s still interested in recruiting your help.

Change you can count on.  Change you can believe in.  Change we need.

What sort of thing did that campaign unleash?  We’re still learning.


Obama didn’t start the sub-prime mortgage crisis

October 12, 2008

The intensity of the rabid attacks on Barack Obama is troubling. The issues grow more bizarre, the links to Obama grow more tenuous, and the shouts more shrill.

And that’s from the reasonable opponents of Obama.

For example, over at the oddly-named IUSB Vision Weblog (Indiana University – South Bend), there is much yammering about how Barack Obama personally is responsible for the sub-prime mortgage industry collapse, because he represented an ACORN client in a redlining case and won the decision from the judge.

From there, the story trails off into a rabbit warren of wild conspiracy theories and the granting of supernatural powers to Obama (though the authors wouldn’t admit it’s supernatural). For example, there is this post about a letter Sen. McCain signed urging some action on oversight of federal mortgage refinancers.

The authors stoutly defend their bizarre claim that Congress is the agency responsible for the regulation of Fannie Mae and Freddie Mac through the OFHEO, Office of Federal Housing Enterprise Oversight. Congress maintains its usual oversight over the executive branch agency, but it is, after all, an executive branch agency. Think about your high school civics classes: Separation of Powers, Checks and Balances.

Congress is not the superintendent of OFHEO

Here is OFHEO’s mission statement — notice no reference to being in Congress’s chain of command:

OFHEO’s mission is to promote housing and a strong national housing finance system by ensuring the safety and soundness of Fannie Mae (Federal National Mortgage Association) and Freddie Mac (Federal Home Loan Mortgage Corporation). OFHEO works to ensure the capital adequacy and financial safety and soundness of two housing government-sponsored enterprises (GSEs) — Fannie Mae and Freddie Mac. Fannie Mae and Freddie Mac are the nation’s largest housing finance institutions. They buy mortgages from commercial banks, thrift institutions, mortgage banks, and other primary lenders, and either hold these mortgages in their own portfolios or package them into mortgage-backed securities for resale to investors. These secondary mortgage market operations play a major role in creating a ready supply of mortgage funds for American homebuyers. Combined assets and off-balance sheet obligations of Fannie Mae and Freddie Mac were $4.2 trillion at year-end 2005.

Fannie Mae and Freddie Mac are Congressionally-chartered, publicly-owned corporations whose shares are listed on the New York Stock Exchange. Under terms of their GSE charters, they are exempt from state and local taxation and from registration requirements of the Securities and Exchange Commission. Each firm has a back-up credit line with the U.S. Treasury.

OFHEO’s oversight responsibilities include:

Conducting broad based examinations of Fannie Mae and Freddie Mac; Developing a risk-based capital standard, using a “stress test” that simulates stressful interest rate and credit risk scenarios; Making quarterly findings of capital adequacy based on minimum capital standards and a risk-based standard; Prohibiting excessive executive compensation; Issuing regulations concerning capital and enforcement standards; and Taking necessary enforcement actions.

OFHEO is funded through assessments of Fannie Mae and Freddie Mac. OFHEO’s operations represent no direct cost to the taxpayer. In its safety and soundness mission, OFHEO has regulatory authority similar to such other federal financial regulators as the Federal Deposit Insurance Corporation, the Office of the Comptroller of the Currency, the Office of Thrift Supervision and the Board of Governors of the Federal Reserve System.

The legislation that established OFHEO also requires Fannie Mae and Freddie Mac to meet certain affordable housing goals set annually by the Secretary of Housing and Urban Development. These goals specify the share of mortgages that the two GSEs are required to purchase annually from low-income, moderate-income and central-city homebuyers.

And, explaining its role in mortgage refinance regulation:

OFHEO was established as an independent entity within the Department of Housing and Urban Development by the Federal Housing Enterprises Financial Safety and Soundness Act of 1992 (Title 13 of P.L. 102-550). The agency is headed by a Director appointed by the President for a five-year term.

OFHEO’s primary mission is ensuring the capital adequacy and financial safety and soundness of two government-sponsored enterprises, the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac). Fannie Mae and Freddie Mac are congressionally-chartered, publicly-owned corporations whose shares are listed on the New York Stock Exchange.

Fannie Mae and Freddie Mac are the nation’s largest housing finance institutions. They buy mortgages from commercial banks, thrift institutions, mortgage banks, and other primary lenders, and either hold these mortgages in their own portfolios or package them into mortgage-backed securities for resale to investors. These secondary mortgage market operations play a major role in creating a ready supply of mortgage funds for American homebuyers. Combined assets and off-balance sheet obligations of Fannie Mae and Freddie Mac were more than $4.2 trillion at year-end 2005, which represents over 40 percent of mortgages outstanding.

In fulfilling its role in the secondary mortgage market, OFHEO promotes housing and a strong national housing finance system.

OFHEO’s oversight responsibilities include the following:
– Conducting broad-based and targeted examinations of Fannie Mae and Freddie Mac
– Making quarterly findings of capital adequacy based on a minimum capital standard and a risk-based capital standard
– Administering a risk-based capital standard, using a “stress test” that simulates interest rate and credit risk scenarios
– Prohibiting excessive executive compensation
– Issuing regulations concerning capital and enforcement standards
– Taking necessary enforcement actions
– Issuing an annual Report to Congress on the financial and operational condition of the Enterprises

OFHEO is funded through assessments on Fannie Mae and Freddie Mac. OFHEO’s operations represent no direct cost to the taxpayer.

The website for the agency is clear that it resides in the Department of Housing and Urban Development (HUD), though it is an independent agency whose director is appointed by the president for a five-year term. When I posted this information at IUSB Vision, however, it was censored. Instead, I got this charming response from the immoderator:

Ed – Stop lying,

You did not read the links. You need to start reading at OFHEO.gov and go and read the links I provided. OFHEO reports to Congress, not the administration. It is a fact. Deal with it. All you have to do is go read on their site THEY will tell you.

Charming fellow. He has censored all of my comments since then. At one point he was lecturing me that I didn’t know the organization. I pointed out to him that the Constitution makes clear the lines of organization in this case: OFHEO is an independent agency within the executive branch. It works closely with the Secretary of HUD. The organization charts show it is not a Congressional agency.

Similarly, this fellow is convinced that Obama, as a lawyer, made the federal courts dance to his tune. He appears to have no understanding for how federal courts work, nor for how a federal judge would regard any attorney acting as arrogantly as they claim Obama did.

Object lesson: You cannot reason a person out of a position he did not get to by reason in the first place.

Election, come soon!
