  • Independence of models and errors

    Roger Pielke’s blog has an interesting guest post by Ryan Meyer, reporting on a paper that questions the meaning of claims about the robustness of conclusions from multiple models. From the abstract:

    Climate modelers often use agreement among multiple general circulation models (GCMs) as a source of confidence in the accuracy of model projections. However, the significance of model agreement depends on how independent the models are from one another. The climate science literature does not address this. GCMs are independent of, and interdependent on one another, in different ways and degrees. Addressing the issue of model independence is crucial in explaining why agreement between models should boost confidence that their results have basis in reality.

    Later in the paper, they outline the philosophy as follows,

    In a rough survey of the contents of six leading climate journals since 1990, we found 118 articles in which the authors relied on the concept of agreement between models to inspire confidence in their results. The implied logic seems intuitive: if multiple models agree on a projection, the result is more likely to be correct than if the result comes from only one model, or if many models disagree. … this logic only holds if the models under consideration are independent from one another. … using multiple models to analyze the same system is a ‘‘robustness’’ strategy. Every model has its own assumptions and simplifications that make it literally false in the sense that the modeler knows that his or her mathematics do not describe the world with strict accuracy. When multiple independent models agree, however, their shared conclusion is more likely to be true.

    I think they’re barking up the right tree, but one important clarification is in order. We don’t actually care about the independence of models per se. In fact, if we had an ensemble of perfect models, they’d necessarily be identical. What we really want is for the models to be right. To the extent that we can’t be right, we’d at least like to have independent systematic errors, so that (a) there’s some chance that mistakes average out and (b) there’s an opportunity to diagnose the differences.

    For example, consider three models of gravity, of the form F=G*m1*m2/r^b. We’d prefer an ensemble of models with b = {1.9,2.0,2.1} to one with b = {1,2,3}, even though some metrics of independence (such as the state space divergence cited in the paper) would indicate that the first ensemble is less independent than the second. This means that there’s a tradeoff: if b is a hidden parameter, it’s harder to discover problems with the narrow ensemble, but harder to get good answers out of the dispersed ensemble, because its members are more wrong.

    For climate models, ensembles provide some opportunity to discover systematic errors from numerical schemes, parameterization of poorly-understood sub-grid scale phenomena and program bugs, to the extent that models rely on different codes and approaches. As in my gravity example, differences would be revealed more readily by large perturbations, but I’ve never seen extreme conditions tests on GCMs (although I understand that they at least share a lot with models used to simulate other planets). I’d like to see more of that, plus an inventory of major subsystems of GCMs, and the extent to which they use different codes.

    While GCMs are essentially the only source of regional predictions, which are a focus of the paper, it’s important to realize that GCMs are not the only evidence for the notion that climate sensitivity is nontrivial. For that, there are also simple energy balance models and paleoclimate data. That means that there are at least three lines of evidence, much more independent than GCM ensembles, backing up the idea that greenhouse gases matter.

    It’s interesting that this critique comes up with reference to GCMs, because it’s actually not GCMs we should worry most about. For climate models, there are vague worries about systematic errors in cloud parameterization and other phenomena, but there’s no strong a priori reason, other than Murphy’s Law, to think that they are a problem. Economic models in the climate policy space, on the other hand, nearly all embody notions of economic equilibrium and foresight which we can be pretty certain are wrong, perhaps spectacularly so. That’s what we should be worrying about.

  • ACCESS releases cross platform VOIP service for Windows Mobile, other OS’s

    diagram4

    ACCESS CO. today announced NetFront™ IP-Phone, a full scale VoIP solution with 3G and Wi-Fi air interfaces designed to support all three major smartphone operating systems: iPhone, Android™ and Windows Mobile®. Jointly developed by ACCESS and OAT, NetFront IP-Phone is designed for commercial use by operators, Internet Service Providers (ISPs?and Mobile Virtual Network Operators (MVNOs). The solution will be available from ACCESS worldwide as of June 2010.

    NetFront IP-Phone, which supports air interfaces for 3G and wireless LAN (Wi-Fi) connections and major global standards, provides a standard middleware application as well as an implementation solution service. NetFront IP-Phone is able to communicate with a variety of IP telephony servers, making it possible for ISPs and MVNOs to offer high-quality VoIP services to smartphone users while substantially reducing development time and costs.

    The NetFront IP-Phone interface is compliant with 3GPP?Third Generation Partnership Project?, OMA?Open Mobile Alliance? and IETF?Internet Engineering Task Force? industry standards. NetFront IP-Phone is not bundled with specific services, so ISPs and MVNOs can customize it to offer differentiated IP telephony services.

    NetFront IP-Phone was developed based on a single design concept for all three major smartphone operating systems (iPhone, Android and Windows Mobile). The high quality VoIP environment was made possible thanks to two key technologies: NetFront™ IMS Client, which supports a base IMS framework, and a standard user interface developed by ACCESS that delivers a rich user experience. The IMS framework deploys eSound™, high-quality VoIP technology developed by OKI, that enables voice communication over IP networks with realistic voice tones that are far superior to conventional phone quality.

    NetFront IP-Phone is designed with a flexible modular architecture, enabling providers to implement unique VoIP applications and combine VoIP services with other applications. Applications are also available as APIs, allowing operators to customize their own UI.

    A VoIP trial server for NetFront IP-Phone is available for providers to evaluate the performance of the service, resulting in reduced cost and evaluation time.

    "Thanks to the combination of world-class mobile software from ACCESS, high-quality audio technology from Oki Electric Industry and IMS technologies from OKI ACCESS, we have produced full scale VoIP solution for smartphones," said Tomihisa Kamada, president, CEO and co-founder of ACCESS. "We will continue to partner with OKI ACCESS and Oki Electric Industry to create new multimedia communications business opportunities."

  • Morning glories

    It is the jewel of Harvard’s weeklong Commencement celebration, the morning on which the Yard is crowded with graduates old and new, and in which pomp and play and pride seek full measure.

    “That’s the idea, that nothing changes,” said Victor Ford ’53 of the Commencement pageantry today (May 27). Ford, pastor emeritus at First Church in nearby Charlestown, where College benefactor John Harvard worshiped, stood with his cane near Johnston Gate.

    Beginning the day was the traditional Senior Class Chapel Service at the Memorial Church. The dais belonged to Rev. Peter J. Gomes, the Plummer Professor of Christian Morals and Pusey Minister in the Memorial Church.

    “You have not survived four years here simply to be lost in the universe,” Gomes told the seniors, some of them sitting up on the altar and some spilling into the aisles. “Something of the greatness and the goodness that is in each of you will survive, and in certain cases even prevail.”

    He cautioned the students against striving for the kind of greatness that is too often tied to a drive simply to achieve. Instead, Gomes urged the graduating class to aim, above all, for goodness.

    Gomes acknowledged that some listeners may perform great deeds, such as finding a cure for cancer or a “sensible way of explaining the economy,” and that he would be grateful for their successes. But he suggested that most of the graduates would simply be “called upon to do small and ordinary things as well as possible.”

    Gomes added, “If you do that well, you will have remade our world and your little corner of it, you will have justified our high hopes in you, and you will have given substance to the ancient vision for a new heaven and a new Earth.”

    “Know that the world will be a better place,” he said, “for your honest participation in it.”

    Gomes’ message resonated with Laurel Macey of Winthrop House, a human evolutionary biology concentrator who will work in a research lab at the Harvard School of Public Health in the fall.

    “I liked that he reminded us that we should not strive for greatness, we should just strive for goodness, and then great things will follow,” she said. “That’s an important message for Harvard students … that sometimes it is more important to just be good.”

    Excitement rose in the Old Yard as seniors, alumni, faculty, and staff gathered to form their long procession lines. The parade, an annual ritual replete with bright, multicolored academic gowns and hoods, processes through the Yard and into Tercentenary Theatre, the outdoor area between the Memorial Church and Widener Library, which was first used in 1936 as a ceremonial gathering point to celebrate the College’s 300th anniversary.

    Fred Abernathy, Gordon McKay Professor of Mechanical Engineering and Abbott and James Lawrence Research Professor of Engineering, stood atop his traditional small podium near Johnston Gate and organized the procession. He called out facts and figures from years gone by to correspond with a particular alumni class, as well as humorous quips.

    “Slowly for the honorands. Don’t march too fast; it is not a race,” said Abernathy of the group of speedy honorary degree recipients hurrying by, which included actress Meryl Streep. She wore tinted glasses and a pair of impressively high wedge shoes.

    Inside the Yard, Sheriff of Middlesex County James V. DiPaola opened the Morning Exercises with three sharp raps of his silver-tipped staff. His call was loud, resonant, and stentorian: “This meeting will be in order.”

    The words are one of the traditions during Commencement Week’s biggest day. But a few things do change — the degree recipients, for one, all 7,125 of them this year, on the 359th Commencement. The recipients of honorary degrees change too. There were 10 this year, from retired U.S. Supreme Court Associate Justice David H. Souter ’61, LL.B. ’66, to education innovator Freeman A. Hrabowski III and iconic actress Meryl Streep.

    But even the honorands can’t escape at least one short-term Harvard tradition: the tight, bright, punning descriptions of them by President Drew Faust. “A formidable man of steel,” she called sculptor-in-metal Richard Serra, “he has knocked sculpture off its pedestal.”

    Harvard Provost Steven Hyman brought his own game to Faust’s wordplay. “Merrily we honor,” he said in an introduction, “Meryl Streep.” The Academy Award-winning actress, who sat on stage next to Souter, stood and blew a kiss to the audience when her degree was conferred. Though it wasn’t her hardest role (Streep has been nominated 16 times for the Oscar, winning two), it was the performance everyone had been waiting for. The crowd went wild.

    There were also wild crowds, School by School, as degrees were conferred on the graduates. The newest grads of Harvard Law School waved wooden gavels. Kennedy School grads threw inflatable globes into the air, and those of the Graduate School of Education waved books.

    For more serious traditions, there are the three orations by graduates.

    The Latin Salutatory by Mary Anne Marks ’10 included a phrase that most observers recognized, “multum laboris,” or, “a great deal of work.” That’s university life, in any language.

    Chiamaka Lilian Nwakeze ’10 delivered the Senior English Address, “Poetry for Chemists,” an argument that a liberal arts education deepens understanding of the sciences. It is “a scaffold on which individuals are formed,” she said, a broad education that bestows “an interconnected consciousness … for a total picture of reality.”

    Comedian James “Jimmy” Tingle, who received a master’s degree in public administration from the Kennedy School, rocked the house with the Graduate English Address, even while confessing he spent his boyhood thinking of Harvard as simply “a good place to steal bicycles.”

    Tingle started as a street performer in Harvard Square. “I don’t want to brag, but two years ago I performed in Europe,” he said, and then paused. “And I have to say: excellent country.”

    Tingle also described his temporary academic stumbling block, a required course in statistics. If he can pass statistics at Harvard, he said, then one other thing is certainly possible: “world peace.”

  • House committee passes bill that will require brake override and black boxes

    President Barack Obama, Vice President Joe Biden dine with House Energy and Commerce Committee

    The U.S. House Energy and Commerce Committee passed a sweeping auto-safety bill that would require installation of brake-override systems and event-data recorders. This bill comes in the wake of the Toyota unintended acceleration crisis, and much pressure from the public to hold automakers more accountable for safety. Regulators would also have to consider industry-wide standards for foot-pedal placement, electronic systems, push-button ignition systems, and transmission configuration. The NHTSA would be the ones to devise a timetable by which the manufacturers would have to be in compliance.

    An earlier version of the bill required that black boxes record crash data for 75 seconds before a crash, and eliminated the cap on penalties to automakers. Those provisions have been dropped; the NHTSA will now determine an appropriate recording window, and the cap has been set at $200 million.

    One other major point of the House bill is the expansion authority and increase in funding to the NHTSA, and that auto-safety information would be more transparent to consumers. A similar bill has been introduced in the Senate; one major difference however, is that the Senate bill would eliminate the cap on fines.

    NHTSA funding will be increased through an automaker fee of $9 per vehicle, and by doubling federal funding to $280 million over three years. There will also be a process in place for the Transportation Department to publicly order recalls in certain situations, and impose a ban on federal employees leaving the Transportation Department to go work for automakers immediately afterwards.

  • Text of Justice David Souter’s speech

    When I was younger I used to hear Harvard stories from a member of the class of 1885.  Back then, old graduates of the College who could get to Cambridge on Commencement Day didn’t wait for reunion years to come back to the Yard.  They’d just turn up, see old friends, look over the new crop, and have a cup of Commencement punch under the elms.  The old man remembered one of those summer days when he was heading for the Square after lunch and crossed paths with a newly graduated senior, who had enjoyed quite a few cups of that punch.  As the two men approached each other the younger one thrust out his new diploma and shouted, “Educated, by God.”

    Even with an honorary Harvard doctorate in my hands I know enough not to shout that across the Yard, but the University’s generosity does make me bold enough to say that over the course of nineteen years on the Supreme Court, I learned some lessons about the Constitution of the United States, and about what judges do when they apply it in deciding cases with constitutional issues.  I’m going to draw on that experience in the course of the next few minutes, for it is as a judge that I have been given the honor to speak this before you.

    The occasion for our coming together like this aligns with the approach of two separate events on the judicial side of the national public life:  the end of the Supreme Court’s Term, with its quickened pace of decisions, and a confirmation proceeding for the latest nominee to fill a seat on the Court.  We will as a consequence be hearing and discussing a particular sort of criticism that is frequently aimed at the more controversial Supreme Court decisions:  criticism that the Court is making up the law, that the Court is announcing constitutional rules that cannot be found in the Constitution, and that the Court is engaging in activism to extend civil liberties.  A good many of us, I’m sure a good many of us here, intuitively react that this sort of commentary tends to miss the mark.  But we don’t often pause to consider in any detail the conceptions of the Constitution and of constitutional judging that underlie the critical rhetoric, or to compare them with the notions that lie behind our own intuitive responses.  I’m going to try to make some of those comparisons this afternoon.

    The charges of lawmaking and constitutional novelty seem to be based on an impression of the Constitution and on a template for deciding constitutional claims that go together something like this.  A claim is made in court that the government is entitled to exercise a power, or an individual is entitled to claim the benefit of a right, that is set out in the terms of some particular provision of the Constitution.  The claimant quotes the provision and provides evidence of facts that are said to prove the entitlement that is claimed.  The facts on their face either do or do not support the claim.  If they do, the court gives judgment for the claimant; if they don’t judgment goes to the party contesting the claim.  On this view, deciding constitutional cases should be a straightforward exercise of reading fairly and viewing facts objectively.

    There are, of course, constitutional claims that would be decided just about the way this fair reading model would have it.  If one of today’s 21 year old college graduates claimed a place on the ballot for one of the United States Senate seats open this year, the claim could be disposed of simply by showing the person’s age, quoting the constitutional provision that a Senator must be at least 30 years old, and interpreting that requirement to forbid access to the ballot to someone who could not qualify to serve if elected.  No one would be apt to claim that lawmaking was going on, or object that the age requirement did not say anything about ballot access.  The fair reading model would describe pretty much what happened.  But cases like this do not usually come to court, or at least the Supreme Court, and for the ones that do get there, for the cases that tend to raise the national blood pressure, the fair reading model has only a tenuous connection to reality.

    Even a moment’s thought is enough to show why it is so unrealistic.  The Constitution has a good share of deliberately open-ended guarantees, like rights to due process of law, equal protection of the law, and freedom from unreasonable searches.  These provisions cannot be applied like the requirement for 30 year-old senators; they require more elaborate reasoning to show why very general language applies in some specific cases but not in others, and over time the various examples turn into rules that the Constitution does not mention.

    But this explanation hardly scratches the surface.  The reasons that constitutional judging is not a mere combination of fair reading and simple facts extend way beyond the recognition that constitutions have to have a lot of general language in order to be useful over long stretches of time.  Another reason is that the Constitution contains values that may well exist in tension with each other, not in harmony.  Yet another reason is that the facts that determine whether a constitutional provision applies may be very different from facts like a person’s age or the amount of the grocery bill; constitutional facts may require judges to understand the meaning that the facts may bear before the judges can figure out what to make of them.  And this can be tricky.  To show you what I’m getting at I’ve picked two examples of what can really happen, two stories of two great cases.  The two stories won’t, of course, give anything like a complete description either of the Constitution or of judging, but I think they will show how unrealistic the fair reading model can be.

    The first story is about what the Constitution is like.  It’s going to show that the Constitution is no simple contract, not because it uses a certain amount of open-ended language, but because its language grants and guarantees many good things, and good things that compete with each other and can never all be realized, altogether, all at once.

    The story is about a case that many of us here remember.  It was argued before the Supreme Court of the United States on June 26, 1971, and is known as The Pentagon Papers.  The New York Times and the Washington Post had each obtained copies of classified documents prepared and compiled by government officials responsible for conducting the Vietnam War.  The newspapers intended to publish some of those documents, and the government sought a court order forbidding the publication.

    The issue had arisen in great haste, and had traveled from trial courts to the Supreme Court, not over the course of months, but in a matter of days.  The time was one of high passion, and the claim made by the United States was the most extreme claim known to the constitutional doctrines of freedom to speak and publish.  The Government said it was entitled to a prior restraint, an order forbidding publication in the first place, not merely one imposing a penalty for unlawful publication after the words were out.  The argument included an exchange between a great lawyer appearing for the Government and a great judge, and the colloquy between them was one of those instances of a grain of sand that reveals a universe.

    The great lawyer for the United States was a man who had spent many Commencement mornings in this Yard.  He was Irwin Griswold, Dean of the Law School for 21 years, who was serving a stint as Solicitor General of the United States.  The great judge who questioned the Dean that day was Mr. Justice Black, the first of the New Deal justices, whom Justice Cardozo described as having one of the most brilliant legal minds he had ever met with.  The constitutional provision on which their exchange centered was the First Amendment, which includes the familiar words that “Congress shall make no law… abridging the freedom of speech, or of the press.”  Although that language by its literal terms forbade Congress from legislating to abridge free expression, the guarantees were understood to bind the whole government, and to limit what the President could ask a court to do.  As for the remainder of the provision, though, Justice Black professed to read it literally.  When it said there shall be no law allowed, it left no room for any exception; the prohibition against abridging freedom of speech and press was absolute.  And in fairness to him, one must say that on their face the First Amendment clauses seem as clear as the requirement for 30 year old senators, and that no guarantee of the Bill of Rights is more absolute in form.

    But that was not the end of the matter for Dean Griswold.  Notwithstanding the language, he urged the Court to say that a restraint would be constitutional when publication threatened irreparable harm to the security of the United States, and he contended there was enough in the record to show just that; he argued that the intended publications would threaten lives, and jeopardize the process of trying to end the war and recover prisoners, and erode the government’s capacity to negotiate with foreign governments and through foreign governments in the future.

    Justice Black responded that if a court could suppress publication when the risk to the national interest was great enough, the judges would be turned into censors.  Dean Griswold said he did not know of any alternative.  Justice Black shot back that respecting the First Amendment might be the alternative, and to that, Dean Griswold replied in words I cannot resist quoting:

    “The problem in this case,” he said, “is the construction of the First Amendment.

    “Now Mr. Justice, your construction of that is well-known, and I certainly respect it.  You say that no law means no law, and that should be obvious.  I can only say, Mr. Justice, that to me it is equally obvious that “no law” does not mean “no law,” and I would seek to persuade the Court that that is true.

    “As Chief Justice Marshall said, so long ago, it is a Constitution we are interpreting…”

    The Government lost the case and the newspapers published, but Dean Griswold won his argument with Justice Black.  To show, as he put it, that “no law” did not mean “no law,” Dean Griswold had pointed out that the First Amendment was not the whole Constitution.  The Constitution also granted authority to the government to provide for the security of the nation, and authority to the President to manage foreign policy and command the military.

    And although he failed to convince the Court that the capacity to exercise these powers would be seriously affected by publication of the papers, the Court did recognize that at some point the authority to govern that Dean Griswold invoked could limit the right to publish.  The Court did not decide the case on the ground that the words “no law” allowed of no exception and meant that the rights of expression were absolute.  The Court’s majority decided only that the Government had not met a high burden of showing facts that could justify a prior restraint, and particular members of the Court spoke of examples that might have turned the case to go the other way.  Threatened publication of something like the D-Day invasion plans could have been enjoined; Justice Brennan mentioned a publication that would risk a nuclear holocaust in peacetime.

    Even the First Amendment, then, expressing the value of speech and publication in the terms of a right as paramount as any fundamental right can be, does not quite get to the point of an absolute guarantee.  It fails because the Constitution has to be read as a whole, and when it is, other values crop up in potential conflict with an unfettered right to publish, the value of security for the nation and the value of the President’s authority in matters foreign and military.  The explicit terms of the Constitution, in other words, can create a conflict of approved values, and the explicit terms of the Constitution do not resolve that conflict when it arises.  The guarantee of the right to publish is unconditional in its terms, and in its terms the power of the government to govern is plenary.  A choice may have to be made, not because language is vague but because the Constitution embodies the desire of the American people, like most people, to have things both ways.  We want order and security, and we want liberty.  And we want not only liberty but equality as well.  These paired desires of ours can clash, and when they do a court is forced to choose between them, between one constitutional good and another one.  The court has to decide which of our approved desires has the better claim, right here, right now, and a court has to do more than read fairly when it makes this kind of choice.  Choices like the ones the Justices envisioned in the Papers case make up much of what we call law.

    Should the choice and its explanation be called illegitimate law making?  Can it be an act beyond the judicial power when a choice must be made and the Constitution has not made it in advance in so many words?  So much for the notion that all of constitutional law lies there in the Constitution waiting for a judge to read it fairly.

    Now let me tell a second story, not one illustrating the tensions within constitutional law, but one showing the subtlety of constitutional facts.  Again the story is about a famous case, and a good many of us here remember this one, too:  Brown v. Board of Education from 1954, in which the Supreme Court unanimously held that racial segregation in public schools imposed by law was unconstitutional, as violating the guarantee of equal protection of the law.

    Brown ended the era of separate-but-equal, whose paradigm was the decision in 1896 of the case called Plessy v. Ferguson, where the Supreme Court had held it was no violation of the equal protection guarantee to require black people to ride in a separate railroad car that was physically equal to the car for whites.  One argument offered in Plessy was that the separate black car was a badge of inferiority, to which the Court majority responded that if black people viewed it that way; the implication was merely a product of their own minds.  Sixty years later, Brown held that a segregated school required for black children was inherently unequal.

    For those whose exclusive norm for constitutional judging is merely fair reading of language applied to facts objectively viewed,  Brown must either be flat-out wrong or a very mystifying decision.  Those who look to that model are unlikely to think that a federal court back in 1896 should have declared legally mandated racial segregation unconstitutional.  But if Plessy was not wrong, how is it that Brown came out so differently?  The language of the Constitution’s guarantee of equal protection of the laws did not change between 1896 and 1954, and it would be hard to say that the obvious facts on which Plessy was based had changed, either.  While Plessy was about railroad cars and Brown was about schools, that distinction was no great difference.  Actually, the best clue to the difference between the cases is the dates they were decided, which I think point to the explanation for their divergent results.

    As I’ve said elsewhere, the members of the Court in Plessy remembered the day when human slavery was the law in much of the land.  To that generation, the formal equality of an identical railroad car meant progress.  But the generation in power in 1954 looked at enforced separation without the more revolting background of slavery to make it look unexceptional by contrast.  As a consequence, the judges of 1954 found a meaning in segregating the races by law that the majority of their predecessors in 1896 did not see.  That meaning is not captured by descriptions of physically identical schools or physically identical railroad cars.  The meaning of facts arises elsewhere and its judicial perception turns on the experience of the judges, and on their ability to think from a point of view different from their own.  Meaning comes from the capacity to see what is not in some simple, objective sense there on the printed page.  And when the judges in 1954 read the record of enforced segregation it carried only one possible meaning: it expressed a judgment of inherent inferiority on the part of the minority race.  The judges who understood the meaning that was apparent in 1954 would have violated their oaths to uphold the Constitution if they had not held the segregation mandate unconstitutional.

    Did the judges of 1954 cross some line of legitimacy into law making, stating a conclusion that you will not find written in the Constitution?  Was it activism to act based on the current meaning of facts that at a purely objective level were about the same as Plessy’s facts 60 years before?  So much for the assumption that facts just lie there waiting for an objective judge to view them.

    Let me, like the lawyer that I am, sum up the case I’ve tried to present this afternoon.  The fair reading model fails to account for what the Constitution actually says and fails just as badly to understand what judges have no choice but to do.  The Constitution is a pantheon of values, and a lot of hard cases are hard because the Constitution gives no simple rule of decision for the cases in which one of the values is truly at odds with another.  Not even its most uncompromising and unconditional language can resolve the potential tension of one provision with another, tension the Constitution’s Framers left to be resolved another day; and another day after that, for our cases can give no answers that fits all conflicts, and no resolutions immune to rethinking when the significance of old facts may have changed in the changing world.  These are reasons enough to show how egregiously it misses the point to think of judges in constitutional cases as just sitting there reading constitutional phrases fairly and looking at reported facts objectively to produce their judgments.

    The fair reading model has all that to answer for, but more than just that.  For the tensions that are the stuff of judging in so many hard constitutional cases are, after all, the products of our aspirations to value liberty, as well as order, and fairness and equality, as well as liberty.  And the very opportunity for conflict between the good and the good reflects our confidence that a way may be found to resolve it when a conflict arises.  That is why the simplistic view of the Constitution devalues those aspirations, and attacks that confidence, and diminishes us.  It is a model of judging that means to discourage our tenacity (our sometimes reluctant tenacity) to keep the constitutional promises the Nation has made.

    So, it is tempting to dismiss the critical rhetoric of law making and activism as simply a rejection of at least some of the hopes we profess to share as the American people.  But there is one thing more.  I have to believe that something deeper is involved, and that behind most dreams of a simpler Constitution lies a basic human hunger for the certainty and control that the fair reading model seems to promise.  And who has not felt that same hunger?  Is there any one of us who has not lived through moments, if not years, of longing for a world without ambiguity, and for the stability of something unchangeable in human institutions?  I don’t forget my own longings which heartily resisted the pronouncement of Justice Holmes, which I read as an undergraduate, that certainty generally is illusion and repose is not our destiny.

    But I have come to understand that he was right, and by the same token I understand that I differ from the critics I’ve described not merely in seeing the patent wisdom of the Brown decision, or in espousing the rule excluding unlawfully seized evidence, or in understanding the scope of habeas corpus.  Where I suspect we differ most fundamentally is in my belief that in an indeterminate world I cannot control it is possible to live fully in the trust that a way will be found leading through the uncertain future.  And to me, the future of the Constitution as the Framers wrote it can be staked only upon that same trust.  If we cannot share every intellectual assumption that formed the minds of those who framed the charter, we can still address the constitutional uncertainties the way they must have envisioned, by relying on reason that respects the words the Framers wrote, by facing facts, and by seeking to understand their meaning for the living.

    That is how a judge lives in a state of trust, and I know of no other way to make good on the aspirations that tell us who we are, and who we mean to be, as the people of the United States.

  • Obama preaches green tech gospel to California choir

    by Todd Woody.

    Silicon Valley in the Internet age has not made for great
    presidential photo ops. The Valley’s computer-chip factories were off-shored
    decades ago and (Google accepted) the software giants that supplanted hardware companies just
    didn’t have the same pizzazz—T-shirted geeks writing code can’t compete with guys and gals in bunny
    suits tending big futuristic machines.

    The rise of green tech has changed all that. The Valley
    is back in the business of building stuff—solar panels, electric cars, fuel cells, and various energy efficient
    widgets and gadgets.

    And so when President Obama’s helicopter landed Wednesday
    morning at Solyndra, a solar module maker, a television-ready tableau awaited—a huge American flag hung in an unfinished factory, shiny high-tech thin-film
    solar panels were on display and workers in hard hats mingled with an audience
    of some 200 engineers, scientists, venture capitalists, and California’s patron
    saint of green tech PR events, Governor Arnold Schwarzenegger.

    “We’ve got to go back to making things. We’ve got to go back
    to exports. We’ve got to go back to innovation,” said Obama on Wednesday
    in Fremont as Solyndra employees snapped photos with their iPhones. 

    “The true engine of economic growth will always be companies
    like Solyndra, will always be America’s businesses,” he continued. “But that
    doesn’t mean the government can just sit on the sidelines.  Government
    still has the responsibility to help create the conditions in which students
    can gain an education so they can work at Solyndra, and entrepreneurs can get
    financing so they can start a company, and new industries can take hold.”

    It’s an apt choice of words, for the fortunes of green tech
    startups like Solyndra have become entwined with the government as the Obama
    administration attempts to jumpstart a transition to a clean energy economy.
    The sprawling solar module plant we’re standing in—its construction is
    employing 3,000 workers—is being financed thanks in large part to a $535
    million loan guarantee the Department of Energy granted to Solyndra last year.

    A few months later, the startup filed for an initial public
    offering. The extensive vetting of Solyndra that the federal government performed
    before issuing the loan guarantee bolstered the company’s IPO (though Solyndra’s cash
    burn rate led auditors to question its viability).

    “This facility would not have been possible in the current
    financial climate without that loan,” Kelly Truman, a Solyndra senior vice
    president, told me as the presidential podium was dismantled and construction
    workers returned to their jobs. “In terms of our business, having the Department of Energy
    give us this loan has certainly given us some credibility because of the
    scrutiny. We went through a year of due diligence.
    Imagine the most conservative bank in the world looking you over.”

    The federal stimulus package’s 30 percent cash tax incentive
    for buyers of rooftop photovoltaic systems like those made by Solyndra has also
    helped keep the solar industry growing at a rapid clip through the Great
    Recession.

    “But we’ve still got more work to do, and that’s why I’m
    going to keep fighting to pass comprehensive energy and climate legislation in
    Washington,” said the president, who called climate change “a threat to our way
    of life.”

    Maybe it was the luxury of being 3,000 miles away from Washington, D.C.
    surrounded by apostles of an alternative energy future while the grim reality
    of the fossil fuel present hung over his head, but Obama spoke more bluntly
    than usual.

    “We all know the price we pay as a country as a result of
    how we produce and use—and, yes, waste—energy today,” he said. “And the
    spill in the Gulf, which is just heartbreaking, only underscores the necessity
    of seeking alternative fuel sources … With the increased risks, the increased
    costs, it gives you a sense of where we’re going. We’re not going to be
    able to sustain this kind of fossil fuel use.”

    A few miles up the road from Solyndra sits the empty hulk of
    the New United Motors Manufacturing Inc. plant. The now-defunct joint venture
    between General Motors and Toyota was California’s only auto manufacturing
    plant when the last Corolla rolled off the line in April. Its closing idled some 5,000
    workers.

    Last week, Tesla Motors, the Silicon Valley electric
    carmaker, announced it was buying the NUMMI factory, tapping a $465 million
    federal loan guarantee to close the deal. Tesla will build its Model S
    battery-powered sedan at the plant and produce electric cars with Toyota,
    putting about a thousand autoworkers back on the line.

    “This is only the beginning,” Obama said, referring to the
    Tesla deal. “We’re investing in advanced battery technologies to power plug-in
    hybrid cars. In fact, today in Tennessee there’s a groundbreaking for an
    advanced battery manufacturing facility that will generate hundreds of
    jobs. And it was made possible by loans through the Department of Energy,
    as well as tax credits and grants to increase demand for these vehicles.”

    No surprise that Obama focused on the green jobs created by
    the federal largesse. But in the long run, that investment will help cutting
    edge technologies to scale. 

    Solyndra emerged
    from stealth mode
    less than two years ago, having raised an initial $600
    million and secured $1.2 billion in orders for its copper-indium-gallium-selenide solar cells. CIGS cells can essentially be printed on flexible
    materials or glass without using expensive silicon. While such solar cells are
    less efficient at converting sunlight into electricity, production costs are
    expected to be significantly lower than making traditional silicon-based
    modules.

    Co-founded by chief executive Chris Gronet, a veteran of
    chip equipment maker Applied Materials, Solyndra’s innovation is to coat long
    glass tubes with CIGS solar cells. Conventional rooftop solar panels must be
    tilted to absorb direct sunlight because they aren’t as efficient at producing
    electricity from diffuse light. But the round Solyndra module collects sunlight
    from all angles, including rays reflected from rooftops. That allows the
    modules, 40 to a panel, to sit flat and packed tightly together on
    commercial rooftops, maximizing the amount of space for power production.

    While some commentators have questioned whether the DOE loan to Solyndra should have been directed at competitors with
    lower costs, there’s no doubt that the company is a contender in an ever
    competitive global market.

    “There are factories like this being built in China,
    factories like this being built in Germany,” said Obama. “Nobody is
    playing for second place. These countries recognize that the nation that
    leads the clean energy economy is likely to lead the global economy. And
    if we fail to recognize that same imperative, we risk falling behind. We
    risk falling behind.”

  • Palm users report vastly improved in-store AT&T experiences

    Palm’s poorly executed launch on Verizon Wireless was undoubtedly the final nail in the coffin in what forced the company to evaluate its options and subsequently find a buyer in HP.  One oft-cited reason cited for that launch going south was the lack support and enthusiasm from Verizon’s sales staff as reported by many new Pre Plus and Pixi Plus users on that carrier.

    Palm has seemingly learned its lesson, as things have drastically improved with the company’s launch on AT&T.  PreCentral forum members are reporting that the sales staff have been highly knowledgeable, well-trained and enthusiastic about Palm’s products, to the point that many are saying that there were no attempts to dissuade their purchase of a Pre Plus with talk of other popular smartphones on the network. We imagine that AT&T’s internal program to promote the device by offering free Pre phones to salespeople who sold the most Palm phones didn’t hurt, either.

    Tell us, new AT&T Pre Plus users: how was your in-store experience?

  • Engineers Temporarily Stopped Oil Leak in Gulf of Mexico

    Engineers have confirmed that they had been able to stop the flow of oil and gas into the Gulf of Mexico temporarily. Oil and gas gushing out of British Petroleum well has been a concern for authorities for the ecological damage it has threaten to do to the marine life and also loss of resources.

    The ‘top-kill’ effort was launched on Wednesday afternoon under top-oil spill commander, U.S. Coast Guard Adm. Thad Allen and had been successful by Thursday morning. The government and industry engineers used the technique of pumping enough drilling fluid to block gas and oil disgorging from the well. However the officials made cautious statement referring that this is not the permanent solution to the problem.



    Though the spill of oil and gas has temporarily stopped, but till early Thursday morning, neither BP officials nor government spokesman have confirmed this effort as successful operation. However Allen seems to be optimistic and said that one ship that was pumping fluid into the well ran out of fluid and the second ship is on its way. He got encouraged by the process and said that they would soon get the situation under control.

    Allen also mentioned about an interagency team that would work to find out an estimate of how much oil got spilled into the gulf. The Coast Guard had estimated that nearly 5,000 barrels of oil got spilled a day, but the independent agencies are estimating that the figure could be much higher than 5,000 barrel a day.

  • Toyota distributor recalls 420,000 vehicles for tire lables

    Distributors for Toyota, the world’s largest automaker, are recalling more than 420,000 vehicles due to labels that detail the load-carrying capacity of tires being either missing or less accurate than required. The recalls were executed by Gulf States Toyota Inc. of Houston, and Southeast Toyota Distributors of Deerfield Beach, Fla., and posted on the NHTSA’s website.

    Owners of the affected vehicles will be notified by mail. Sierra, Prius, Camry, and Corolla models from 2005-2011 have been affected.

    “The true vehicle load-carrying capacity is important to know,” said Brian Lyons, a spokesman for Toyota’s U.S. unit, based in Torrance, California.

    A National Traffic Safety Administration spokesperson had no immediate comment to make.

  • Oily Gulf Seafood Will Literally Be Sniff Tested By Expert Smellers

    Oil from the explosion of Deepwater Horizon is flooding the waters of some of the most productive coastal fishing areas in the world, says ABC News, so how will the FDA ensure that no oily fish make it into the food system? They’re gonna smell it. With their noses.

    From ABC:

    “The human nose is a powerful instrument,” said Steve Otwell, who leads the University of Florida’s professional seafood sensory school. Otwell will help train about 25 persons from the National Marine Fisheries Service and the federal Food and Drug Administration on the Gainesville campus beginning in a few days.

    He went on to say that there will be naysayers, but human noses are quick, cheap and pretty reliable.

    “You will have the purists, and the lawyers, and everyone else say we need to have a very sensitive chemical method to really determine what’s there,” he told ABC. “And that’s absolutely true. But the amount of time, the lack of such instrumentation, and the costs make it impractical to depend on that technology to scrutinize the variety of seafood and the variety of areas that’s involved with this particular spill.”

    “It is a science and the human nose can indeed detect levels that can provide us with a safety level, but the nose has to be trained. And some noses are better than others,” he said.

    Of course the pelicans don’t have the FDA watching out for them, so they’re out of luck.

    JP Morgan has called the lawsuit “ill-conceived”.

  • Justin Bieber Walks Into Glass Door….Again

    Poor Justin Bieber — the pint-sized singer has had another unfortunate run-in with a door, and it was all caught on camera….

    “yes it is true…i almost nailed my head on a glass door again…almost,” the teen crooner Tweeted Thursday, linking to this video of him slightly clipping his head on a sliding glass door while trying to exit a building.

    Thankfully he was unhurt, laughing off the incident when he saw the cameraman, but this isn’t Justin’s first time having a bad experience with glass. Last week, Bieber was leaving a Radisson Hotel when his famous head smashed into the glass of the establishment’s revolving door.

    Perhaps it’s time to trim the bangs, Biebs. Or at least invest in a sturdy pair of glasses!


  • Motorola CEO Sanjay Jha talks Android, more devices for Verizon

    Motorola Shadow

    It seems there has been Verizon news trickling out of the Barclays Capital Global Communications, Media & Technology conference almost every day this week, and now we’ve got more news for you.  Speaking at the Barclays conference, Motorola CEO Sanjay Jha had quite a bit to say about Android, Verizon, and the company’s plans for future devices.  Jha explained that nearly all of his focus is on Android and that the company would be “aggressive” in bringing Android 2.2 to its phones.

    When asked about HTC, Jha responded by saying that he wasn’t concerned that devices like the Incredible would eat into his company’s phone sales because Motorola has more Droid phones for Verizon in the pipeline.  We’re assuming one of the devices he is referring to is the Motorola Shadow (DROID 2?), but who knows what else the company has planned.

    Lastly, Jha touted the popularity of Motoblur, saying that the skinned version of Android had surpassed one million users and that a new version would be available later this year.  It looks like Motorola and Verizon are getting pretty cozy lately, but here’s to hoping that Moto will bring some quality DROID-like devices to other carriers, such as AT&T.

  • Where Job Searches Take the Longest

    The Economic Policy Institute has posted a new study of the average duration of unemployment by state. The report shows that workers wait longest for jobs in Michigan and South Carolina, and that last month “the median length of unemployment in the United States was 21.6 weeks, up from 15.1 weeks in 2009 and well over double the median unemployment spell of 8.4 weeks at the start of the recession in December 2007.” The study includes this map showing the median length of unemployment — or how long it takes, on average, to find a job.

    The map demonstrates the regionalization of the remaining recession: Where it takes longer to get a job, there tends to be a higher rate of unemployment, steeper declines in home values, higher rates of foreclosure and more severe state budget deficits. Compare the above graph with those below.

    This shows the rate of foreclosure (from RealtyTrac).

    And this shows the rate of unemployment (from the Bureau of Labor Statistics).

    And this shows each state’s deficit as a percentage of its budget (from the Center for Budget and Policy Priorities).

    The charts show that states like Michigan, California, Nevada and Florida are fighting harder battles on more fronts — and will take much longer than the rest of the country to normalize economically.
