A(nother) "New" Start

http://soldierforlife.army.mil/retirement/index.html


This month, after 23 years, 8 months, and 27 days (they counted), I retired from the Army. This week, we finished moving out of our last "PCS" house. Next week, we begin the "settling in" process in what we call our "forever house."

I was able to celebrate my retirement with family, friends, and co-workers. We were not able to track down some we wanted to invite, and others we did invite were not able to attend. I want to publicly thank everyone who celebrated with us, apologize to everyone who didn't get an invite and would have wanted to attend, and assure everyone who could not attend that you were there in spirit and in our thoughts.

I owe so much to so many to have reached this milestone. None of my achievements were mine alone. I was never the best among those with whom I served and always better for having served with them.

To my family and friends:

I also wanted to dedicate this post to four people, whom I will never forget:

Jackie Wertman
Dan Winchester
Mike Adams
Joe Sullivan

“To live well, to laugh often, to love much, to gain the respect of intelligent people, to win the love of little children. To fill one’s niche and accomplish one’s task, to leave the world better than one finds it whether by an improved flower, a perfect poem or another life ennobled. To never lack appreciation of earth’s beauty or fail to express it, to always look for the best in others, to give the best one has. To make one’s life an inspiration and one’s memory a benediction. This is success.”*

Memorial ceremonies are patriotic tributes to deceased soldiers....

In most cases, the unit prepares a program that may include a biographical summary of the deceased soldier with mention of awards and decorations. The following elements are commonly part of a memorial ceremony:
  • Prelude (often suitable music).
  • Posting of the Colors.
  • National Anthem.
  • Invocation.
  • Memorial Tribute (e.g., remarks by unit commander or a friend of the deceased).
  • Scripture Reading.
  • Hymn or other special music.
  • Meditation (quiet moment for attendees to reflect).
  • Benediction.
  • Last Roll Call. This is a final tribute paid by soldiers to their fallen comrade. It has its origin in the accountability roll call conducted by the unit First Sergeant following combat. Although sometimes painful to listen through, the Last Roll is called with the conviction held by soldiers that all unit members will be accounted for, and none will ever be forgotten.

Information Assurance as a Service and Abstracting Complexity "Away"

The State of the Internet Operating System

We are once again approaching the point at which the Faustian bargain will be made: simply use our facilities, and the complexity will go away. And much as happened during the 1980s, there is more than one company making that promise. We're entering a modern version of "the Great Game", the rivalry to control the narrow passes to the promised future of computing.
In the world of Information Assurance, there is a strong desire from application and service developers to "abstract away" the complexities of security. Think of this in terms of Security-as-a-Service or an Information Assurance Framework in the cloud. This can be accomplished for difficult security functions, such as handling X.509 certificates using Server-based Certificate Validation Protocol (SCVP) and PKI Resource Query Protocol (PRQP). The complexity is "removed" from the relying party to the trusted Validation Authority. Given the difficulty and risk associated with different certificate validation implementations by relying parties (some implemented more securely than others), this abstraction of complexity "away" from relying parties to a trusted Validation Authority run by an "expert" has advantages. The security experts create and control the security context in which applications will work.

It also means that the relying parties have made a "Faustian bargain" with the security experts that take "on the pain of managing complexity" and end up "with a powerful lock-in."

Straight Talk on Social Security

UPDATE: Josh Marshall

The debate about Social Security is the same as it was in 2005 and in most respects the same as it was in 1965. You have one group who believe in the current system -- which is an intergenerational bargain, insuring a baseline level of retirement security as well as insurance against premature, disability and for dependent children. The other side -- McCain's side -- thinks this is just wrong, morally and economically. And in its place they want to create a system of individual private investment accounts -- similar to a lifetime 401k.

That's the essence of the debate.
MESSAGE TO CONGRESS ON SOCIAL SECURITY. JANUARY 17, 1935
In the important field of security for our old people, it seems necessary to adopt three principles: First, non-contributory old-age pensions for those who are now too old to build up their own insurance. It is, of course, clear that for perhaps thirty years to come funds will have to be provided by the States and the Federal Government to meet these pensions. Second, compulsory contributory annuities which in time will establish a self-supporting system for those now young and for future generations. Third, voluntary contributory annuities by which individual initiative can increase the annual amounts received in old age. It is proposed that the Federal Government assume one-half of the cost of the old-age pension plan, which ought ultimately to be supplanted by self-supporting annuity plans.
Progress and Prospects Under the Social Security Act. May 25, 1937
To be concrete, if we adopt the pay-as-you-go system, we must make absolutely certain that at the same time we not only balance the budget but proceed to retire the government debt within the next generation through the imposition, let us hope, of progressive taxes, in order that we do not reach a period in the future when the burden of the interest charges on a large public debt and the burden of a large government subsidy to the Federal Old-Age Insurance plan cannot be sustained through current taxation.
A Statement on the Automatic Increase in the Tax Rate Under the Federal Old-Age and Survivors Insurance System. November 27, 1944
In my testimony before this Committee last January, I made the following statement: "In the history of social insurance throughout the world the major difficulty of social insurance systems has been the lack of adequate financing of old-age retirement benefits. It is always easiest to delay levying the necessary insurance contributions, thus perpetuating and strengthening the belief that the insurance benefits are meager and the costs of the insurance system are low. Inevitably, when the time comes to increase the taxes, many reasons can always be advanced as to why the imposition of the additional taxes is unwise or impossible. In this country we are still in a position to avoid these mistakes by getting clearly established now that if our people want social insurance they must be willing to pay for it. The time to obtain the necessary contributions is when people are able to pay for the insurance and are willing to pay for it because they can be shown that they are getting their money's worth. If we should let a situation develop whereby it eventually becomes necessary to charge future beneficiaries rates in excess of the actuarial cost of the protection afforded them, we would be guilty of gross inequity and gross financial mismanagement, bound to imperil our social insurance system."
Framing the Social Security Debate: Values, Politics, and Economics. 1998
Competing reform proposals reflect contrasting views about the nature of the Social Security problem and how to solve it. This book examines issues about privatization, national savings and economic growth, the political risks and realities in reforms, lessons from private pension developments in the United States, and the efforts of other advanced industrial countries to adapt their old-age pensions to an aging population. It also poses philosophical arguments about collective versus individual responsibility and the implications of market risks and political risks for stable and secure retirement income policy.
The Real Deal: The History and Future of Social Security, p. 227. 1999
The original architects and builders of our Social Security system, such as Arthur Altmeyer, anticipated exactly the situation we face with pay-as-you-go financing. They thought it would prove to be unfair to future workers, and they did not want to see that eventuality materialize.
The Real Deal: The History and Future of Social Security, p. 202. 1999
We hope that this has convinced you that a pay-as-you-go Social Security system is not without risks. Americans are in this program for an entire lifetime and the risks are considerable. Think about it -- taxes were raised and benefits cut in 1977. Taxes were raised and future benefits cut in 1983. Now we see that the system has a large long-term deficit. Unless we consider changing its very structure, we will have no choice but to raise taxes and cut benefits once again. There aren't a lot of choices for fixing Social Security other than straightforward tax hikes and benefit cuts -- that is unless we set about designing a system that increases our nation's saving rate and ultimately increases the wealth of our children and grandchildren.
An Overview of the Social Security Program. 2001
From Social Security's earliest days, a contentious issue was whether the benefits that workers and their families received should be prefunded using the taxes that those workers paid, rather than the taxes paid by current workers. As the program was enacted in 1935, revenues dedicated to Social Security would have exceeded outlays by enough to build up very large surpluses. In effect, those excess revenues would have helped fund, in advance, the benefits that the same workers would receive later. Opponents of prefunding argued that such an arrangement would result either in pressure to increase spending or in federal government ownership of private assets. Later expansions to the program, along with postponement of increases in the payroll tax rate that were originally scheduled to occur during the 1940s, essentially moved Social Security to a pay-as-you-go basis.(23) That pay-as-you-go structure has worked, although with many changes in taxes and benefits along the way. But it has worked largely because the labor force has grown rapidly during much of the program's history. That situation is about to change, as the number of Social Security beneficiaries begins to increase much faster than the number of workers.

The Media Store
Tune: Sixteen Tons

Some people say a man is made out of mud
A soldier's made out of muscle and blood
Muscle and blood, skin and bones...
A mind that's sharp and a back that's strong

Chorus:
I served sixteen years, and what did I get?
My flag-draped casket all over the 'net
St. Peter, don't you call me, 'cause I can't go
They gave my soul to the Media store

Woke up one mornin' and the sun didn't shine
Boots, rifle, beret made into a shrine
My voice was absent when they called roll
the Chaplain said, "God bless his soul!"

(Chorus)

They carried me slowly thru the drizzlin' rain
and laid me gently on the ramp of the plane
My Brothers in Arms honored my name
A "cost of war," it's a cryin' shame

(Chorus)

Flag-draped caskets came home before
but you weren't there, before the war
You got your photos but there'll be no more
There's no honor in the Media store

UPDATE:
A media protest clouds Marine's final journey
But what bothers me is the way the somber ceremony to honor a man who died for his country got manipulated by the media to create outrage.
Yeah, because those cemetery vultures can't get enough special care and feeding at another man's funeral.

IO, IO, It's off to blog I go!

Jay Rosen pointed me to a blog post over at Noah Shachtman's Danger Room called Military Report: Secretly 'Recruit or Hire Bloggers'.

Oooooh, scary. Shachtman even links to a .zip file copy of the report at cryptome.org! [Because, uh, it's not publicly available? Why, yes it is! link updated, also at USAF Air University]

If you don't know anything about blogs, blog metrics (i.e. sites like technorati) or have never heard of the web's power law (or long tail, which isn't mentioned in the report), then this might be an OK primer. The only eye-catching part of the first 18 pages of the report, for me anyway, was a graphic of Peretti/Bennett's micro-middle-mass media ecology ("infosphere" in the report).

If you do know that stuff, fast forward to page 19, Implications for Influence Operations. Influence Operations are a subset of Information Operations (IO) and are not unique to the military. For example, "culture jamming" is a form of influence operations. So is advertising. Military Information Operations have been around for a while and I'd argue the military was slow to notice the blogosphere. Starting on page 19 of the report, there's about 7 pages of reading pertaining to blogs and IO. Here's a paragraph from the report's conclusion:

One of the significant limitations of this paper, as an initial foray into military use of the blogosphere, is that much of the information available concerns American blogs, run by Americans, largely for an American audience. Military use of the blogosphere must necessarily focus on foreign blogs, bloggers and audiences. However, because some factors, such as the scale-free nature of the Internet and the psychological basis of influence are universals, we hope to lay a general basis for military use of the blogosphere that can be adapted to specific tactical circumstances by information operators.
I don't think Shachtman's post does a good job of representing the report or informing anyone about IO. For example, Shachtman quotes from the report, "clandestinely recruiting or hiring prominent bloggers" and "Hiring a block of bloggers to verbally attack a specific person or promote a specific message may be worth considering." He even provides a long blockquote, with a very strange ellipsis! Below I've provided the preceding paragraph and the first paragraph of Shachtman's blockquote, in italics, with the ellipsis removed:
This discussion of communities leads us to another point of difficulty in using blogs for IO. Segmentary opposition and its gentler cousin, in-group/out-group dynamics, may prevent a foreign audience from taking an overtly U.S. government-run or sponsored blog seriously. Even American blogs show a high incidence of ethnic clustering,39 and the deep-seated fissures between major tribal groups, and often between subgroups, frequently define traditionally tribal societies like those in Afghanistan. Even if there is no widespread preconception about U.S. use of propaganda, it may be easy for foreign audiences to dismiss the U.S. perspective with “Yes, but you aren’t one of us, you don’t really understand us.”

In this regard, information strategists can consider clandestinely recruiting or hiring prominent bloggers or other persons of prominence already within the target nation, group, or community to pass the U.S. message. In this way, the U.S. can overleap the entrenched inequalities and make use of preexisting intellectual and social capital. Sometimes numbers can be effective; hiring a block of bloggers to verbally attack a specific person or promote a specific message may be worth considering.40 On the other hand, such operations can have a blowback effect, as witnessed by the public reaction following revelations that the U.S. military had paid journalists to publish stories in the Iraqi press under their own names.41 People do not like to be deceived, and the price of being exposed is lost credibility and trust. [emphasis mine]
Does that make a difference? I kept the endnotes and linked them because I thought you might enjoy Daniel (of Fake Steve Jobs fame) Lyons' screed linked from endnote 40. I don't know why it didn't get linked by Shachtman in the blockquote. Strangely, Shachtman did link to a NYT story about the Iraqi press roughly corresponding to endnote 41 which, if I was Mark Mazzetti or Borzou Daragahi, I'd be a little upset.

Anyway, I read Danger Room occasionally and sometimes enjoy it. This one, not so much. If you are interested in blogs that cover IO well, I'd recommend SWJ or MountainRunner. You might also be interested in the University of Nebraska at Omaha blog: Information Warfare Online Resources.

Thanks for the pointer, Jay!

UPDATE:
Propaganda: Can a Word Decide a War?
A culture of information empowerment down to the lowest levels needs to be inculcated among senior government officials, permitting for clear guidance provided to subordinates, risk mitigation procedures established, and, perhaps most importantly, acceptance that this will not be a zero-defect undertaking.

Winning hearts, minds, trust, and credibility, in the end, requires a local approach. Consider a major US metropolitan area. Neighborhoods take on their own personalities, driven by socio-economic factors and ethnic and racial identity, among other considerations. Value sets are different among the diversity of communities that make up the melting pot that is a large American city. It should not be difficult then to understand how it is nearly impossible to influence perceptions among audiences in a foreign country with a “one size fits all” set of messages and actions. Long-term US presence and engagement in foreign nations allows for a deeper understanding of cultural differences. These cultural underpinnings combined with the hard work of relationship building allow for effective tailoring of messages and the successful identification of key influencers. Engagement is the key whether it is by US soldiers in their area of operations, diplomats on Provincial Reconstruction Teams, US Agency for International Development workers, or nongovernmental organizations.32 Where no US presence exists, efforts must include recruiting key individuals for US exchange programs, people who will tell this nation’s story upon their return home.

The Mom Song

via Xark, by Anita Renfroe.



Get up now
Get up now
Get up out of bed
Wash your face
Brush your teeth
Comb your sleepyhead
Here's your clothes and your shoes
Hear the words I said
Get up now! Get up and make your bed
Are you hot? Are you cold?
Are you wearing that?
Where's your books and your lunch and your homework at?
Grab your coat and gloves and your scarf and hat
Don't forget! You gotta feed the cat
Eat your breakfast, the experts tell us it's the most important meal of all
Take your vitamins so you will grow up one day to be big and tall
Please remember the orthodontist will be seeing you at 3 today
Don't forget your piano lesson is this afternoon so you must play
Don't shovel
Chew slowly
But hurry
The bus is here
Be careful
Come back here
Did you wash behind your ears?
Play outside, don't play rough, will you just play fair?
Be polite, make a friend, don't forget to share
Work it out, wait your turn, never take a dare
Get along! Don't make me come down there
Clean your room, fold your clothes, put your stuff away
Make your bed, do it now, do we have all day?
Were you born in a barn? Would you like some hay?
Can you even hear a word I say?
Answer the phone! Get off the phone!
Don't sit so close, turn it down, no texting at the table
No more computer time tonight!
Your iPod's my iPod if you don't listen up
Where are you going and with whom and what time do you think you're coming home?
Saying thank you, please, excuse me makes you welcome everywhere you roam
You'll appreciate my wisdom someday when you're older and you're grown
Can't wait till you have a couple little children of your own
You'll thank me for the counsel I gave you so willingly
But right now I thank you not to roll your eyes at me
Close your mouth when you chew, would appreciate
Take a bite maybe two of the stuff you hate
Use your fork, do not burp or I'll set you straight
Eat the food I put upon your plate
Get an A, get the door, don't get smart with me
Get a grip, get in here, I'll count to three
Get a job, get a life, get a PHD
Get a dose of,
"I don't care who started it!
You're grounded until you're 36"
Get your story straight and tell the truth for once, for heaven's sake
And if all your friends jumped off a cliff would you jump, too?
If I've said it once, I've said at least a thousand times before
That you're too old to act this way
It must be your father's DNA
Look at me when I am talking
Stand up straighter when you walk
A place for everything and everything must be in place
Stop crying or I'll give you something real to cry about
Oh!
Brush your teeth, wash your face, put your PJs on
Get in bed, get a hug, say a prayer with mom
Don't forget, I love you
And tomorrow we will do this all again because a mom's work never ends
You don't need the reason why
Because, because, because, because
I said so, I said so, I said so, I said so
I'm the mom, the mom, the mom, the mom, the mom!!
Ta da!!!

Subprime Mortgage History

Janet at Xark! links to a BBC Q&A on the mortgage "crisis."

What we're seeing in the mortgage market is just a piece of the larger credit "crisis" resulting from bad decisions by private lenders and borrowers after deregulation.

The evolution of the subprime mortgage market (pdf, 2006)

Many factors have contributed to the growth of subprime lending. Most fundamentally, it became legal. The ability to charge high rates and fees to borrowers was not possible until the Depository Institutions Deregulation and Monetary Control Act (DIDMCA) was adopted in 1980. It preempted state interest rate caps. The Alternative Mortgage Transaction Parity Act (AMTPA) in 1982 permitted the use of variable interest rates and balloon payments.

These laws opened the door for the development of a subprime market, but subprime lending would not become a viable large-scale lending alternative until the Tax Reform Act of 1986 (TRA). The TRA increased the demand for mortgage debt because it prohibited the deduction of interest on consumer loans, yet allowed interest deductions on mortgages for a primary residence as well as one additional home....

Although the subprime mortgage market emerged in the early 1980s with the adoption of DIDMCA, AMTPA, and TRA, subprime lending rapidly grew only after 1995, when MBS with subprime-loan collateral become more attractive to investors....

During the 1990s, average credit scores tended to decline each year, particularly for ARM borrowers; but since 2000, credit scores have tended to improve each year. Hence, it appears that subprime lenders expanded during the 1990s by extending credit to less-credit-worthy borrowers. Subsequently, the lower credit quality unexpectedly instigated higher delinquency and default rates (see also Temkin, Johnson, and Levy, 2002).
TREASURY DEPUTY ASSISTANT SECRETARY MICHAEL S. BARR
REMARKS TO THE NATIONAL ASSOCIATION OF ATTORNEYS GENERAL PREDATORY LENDING SUMMIT
PORTLAND, MAINE (2000)
When lower-income families went looking for home equity debt in the past, many may not have been able to find it due to their limited or poor credit history. With the rise of the subprime lending market, however, it has become relatively easier for these borrowers to access credit. As the Treasury-HUD report noted, the volume of subprime mortgage originations has increased nearly five times over in the last five years. As a means for expanding the availability of credit, the development of this market has represented a signal achievement for our economy.

An Anthology of Journalism's Decline

Hutchins' Report: A Free And Responsible Press (1947)

Today our society needs, first, a truthful, comprehensive, and intelligent account of the day's events in a context which gives them meaning; second, a forum for the exchange of comment and criticism; third, a means of projecting the opinions and attitudes of the groups in the society to one another; fourth, a method of presenting and clarifying the goals and values of the society; and, fifth, a way of reaching every member of the society by the currents of information, thought, and feeling which the press supplies.
Objectivity as Strategic Ritual: An Examination of Newsmen's Notions of Objectivity (1972)
To journalists, like social scientists,2 the term "objectivity" stands as a bulwark between themselves and critics. Attacked for a controversial presentation of "facts," newspapermen invoke their objectivity almost the way a Mediterranean peasant might wear a clove of garlic around his neck to ward off evil spirits.
Untended Gates: The Mismanaged Press (1986)
The unprofessional gatekeeper system clearly has to be judged as being one of the root causes of the steady slide of public confidence in journalism.
Governing with the News: The News Media as a Political Institution (1998)
Instead, the news media share more with two other political institutions: the political parties, and the interest group system.
Uncertain Guardians: The News Media as a Political Institution (1999)
In this book I build on the work of Cater and his successors, Leon Sigal and Herbert Cans in particular, to explain why the news media effectively constitute a political institution and why this fact matters to students of American politics.
Snob Journalism: Elitism Versus Ethics for a Profession in Crisis (2003)
Most journalists don't know the history of their profession, have not read great works of their predecessors and have not read even the small number of major philosophical works produced by journalists.

When psychologist Bill Damon and his colleagues were researching their book "Good Work: When Excellence and Ethics Meet," they found they had never studied a profession that did as poor a job as journalism of handing down the collected wisdom of one generation to another.
The State of the News Media: Public Attitudes (2007)
All that comes, of course, against a background of more than 20 years of growing skepticism about journalists, their companies and the news media as an institution. As we have noted in other reports,since the early 1980s, the public has come to view the news media as less professional, less accurate, less caring, less moral and more inclined to cover up rather than correct mistakes.

A Vision of Students Today

Created by Michael Wesch in collaboration with 200 students at Kansas State University.



UPDATE: Archive for the 'Vision of Students' Category @ Kansas State University Digital Ethnography Blog!

To give a little bit more context to the piece, it might be useful to point out that it was originally created as Part 2 of a 3 part series on Higher Ed. Part 1 has been published as Information R/evolution. That piece tracks the way information creation, critique, and distribution has changed, ending with the question “Are we ready?” and the answer: “R U Feeling Lucky?” (altering Google’s I’m feeling lucky button). Placed back to back, this would then lead directly to the door opening to the empty classroom.

Part 3 is planned to be an exploration of different teaching technologies and the ways in which they shape the learning environment for better and for worse. It will begin where this video left off, with a chalkboard (which IS a teaching *technology*, though we often overlook it as such), progressing through PowerPoint, onto the web, SecondLife, etc.

Clockwise or Counter-Clockwise?

Right Brain v Left Brain

Photo Sharing and Video Hosting at Photobucket

Which Way Is the Dancer Spinning? Some say both ways.

So far, she only spins clockwise for me.

My better half said clockwise at first, but then she focused on a different spot and the dancer changed direction. My oldest sees her change direction with no control over it. My youngest sees her spin clockwise, only.

Not sure if this is related, but I always have trouble seeing the hidden picture in Magic Eye's autostereograms but my wife has no trouble seeing them.

UPDATE: I got her to switch directions! I scrolled the picture down so I could only see the top of her head. When it switched directions, I scrolled the picture up and she was spinning counter-clockwise! It lasted for maybe 20 seconds and then she switched back to spinning clockwise. I was able to repeat the procedure. Weird, huh?

UPDATE: Okay, I can get her to switch directions now while viewing the whole image.

UPDATE: The Spinning Dancer and the Brain

When presented with stimuli that have two valid, mutually contradictory interpretations, your brain just picks one. Then, sometimes, it picks the other. We still don’t understand why this happens, or what role conscious efforts might play in this shift in perception. Many people are able to make the dancer shift directions at will, but the strategies I’ve seen almost always invoke a change of focus - I shift my attention to her feet, or scroll up and down, others look at her hands or to her side. (I’ve also seen lots of people talk about staring at her nipples, but none who report that it helps them see her change directions.)
Heh.
