Ubiquity: Technologies for Better Health in Aging Societies (Studies in Health Technology and Informatics, Vol. 124) (Studies in Health Technology and Informatics)
Arie, Ed. Hasman Manufacturer: IOS Press ProductGroup: Book Binding: Hardcover ASIN: 1586036475 |
Book Description
Information technology helps to improve the quality of healthcare by disseminating and systematizing knowledge of diagnostic and therapeutic possibilities as well as the organization and management of care. Unobtrusive, active, non-invasive technologies, including wearable devices, allow us to continuously monitor and respond to changes in the health of a patient. Such devices range from micro-sensors integrated in textiles, through consumer electronics, to belt-worn personal computers with head mounted displays. Such ubiquitous computing allows us to identify new ways of managing care that promises to be considerably easier in letting patients maintain their good health while enjoying their life in their usual social setting, rather than having to spend much time at costly, dedicated healthcare facilities. It may prove essential for ensuring quality of life as well as healthcare for increasingly aging societies.

The Ubiquity of the Finite: Hegel, Heidegger, and the Entitlements of Philosophy (Studies in Contemporary German Social Thought)
Dennis J. Schmidt Manufacturer: The MIT Press ProductGroup: Book Binding: Paperback Similar Items: ASIN: 0262691396 |
Book Description
What are the assumptions and tasks hidden in contemporary calls to "overcome" the metaphysical tradition? Reflecting upon the internal contradictions of the notions of "tradition" and "finiteness," Dennis J. Schmidt offers novel insights into how philosophy must relate to its traditions if it is to retain a vital sense of the plurality of "edges" that constitute its finiteness. He does this through a close examination of issues found in the work of Hegel and Heidegger, two philosophers who made the ideas of both tradition and finiteness the center of their concern.Customer Reviews:

Earthquakes, market crashes, hurricanes, wars: are these random forces of nature, or foreseeable blips on the radar screen of history? In this lively book, science journalist Mark Buchanan introduces readers to a developing branch of science that looks for order in what seems to be utmost chaos.In the late 1980s, three physicists set out to investigate the apparently inherent instability of complex systems. In a process that Buchanan illustrates by analogy with a sand pile, they discovered that these systems tend to arrive at a "critical state," after which point any random grain falling in just the right place can touch off an avalanche. So it is, Buchanan shows us, with the onset of world wars, economic shocks, traffic gridlock, and other dislocating events--all of which this new science may one day help predict.
In clear and vigorous prose, Buchanan brings readers insights from nonequilibrium physics, offering a new way of seeing the "fingers of instability" that poke through the world's fabric--and that in turn make it such an interesting place. --Gregory McNamee

Can my small comments make a change?.......2002-08-20
On the other hand there was one revelation in this book that truly fascinated me. I have always been interested in the dinosaurs and their extinction. Books like 'The Dinosaur Heresies' by Bakker and 'Hot-Blooded Dinosaurs' by Desmond developed a genuine need-to-know-more. But the matter of extinction is so challenging. There are strong suggestions that an impact of an asteroid caused such havoc that the dinosaurs became extinct - all of them, the small ones, the large ones, the carnivores, the herbivores, the pterosaurs (flying dinosaurs) and the plesiosaurs (sea-going dinosaurs). And yet, for all that, other animals - notably mammals - did survive. What allowed them through the window of extinction? In my reading I have encountered this debate many times and most writers do have a preference for one theory or another. But even those who do support the impact theory do not have evidence of an impact associated with each of the great periods of extinction that have occured through time. So, the thesis of 'Ubiquity' does provide an alternative - that sometimes the effect of even a small change will cause monumental alterations to the world according to the ubiquitous power law. What was the small change that extinguished the dinosaur SPECIES but allowed others to survive, and in the absence of the dinosurs, thrive? It seems to me that knowing what this small change was would fundamentally advance our knowledge of what the dinosaurs really were.
The most powerful voice in the campaign for popularising the impact theory of dinosaur extinction is Alvarez who discovered the site of the impact that occured 65 million years ago just about the time the last dinosaur walked on the Earth. What Buchanan points out, that so few other writers do is this ....
'...the bulk of the long 1980 paper by Alvarez and his colleagues was 'confined to the geological and physical evidence for an impact, and the physical results of the impact. The discussion of the biological results of the impact occupies only half a page. (quoted from M. Benton) The reason is simple: no one really has much of a clue about what an impact would really do to life all over the planet.'
This is perhaps the strongest argument I have read against the impact causing the extinction of the dinsoaurs. Not that it couldn't have, but that the opinionated science community is so set on Alvarez' findings that they have taken the most tenuous suggestions from Alvarez' paper to support their theories.
Certainly plausible and explains a lot.......2002-08-20
Like Bak, Buchanan points out that much that appears to have historical significance and specific causation, while it makes for good story telling, has little predictive value about it. He uses Bak's sandpile experiments to illustrate the futility of such efforts by creating a "Sandman's view" of catastrophe (pp. 179-180). He imagines a catastrophic sand slide from the point of view of a tiny survivor to whom events seem to have been "due" to negligence on the part of the individuals responsible for a steep area. From the point of view of the sandpile, though, the information required for such control would have to be staggeringly large and nearly perfect in order to have predicted the slide and its effects. Had some minute change to the pile been possible at the putative disaster site, a similar slide could have occurred elsewhere. Then the caretakers of the sandpile would have been blamed for causing a disaster rather than preventing one. One can see in this parable why politicians in the real world tend to seek their own ultimate good rather than that of their constituents or of the environment itself. The vagaries of prediction caused by the intertwining of particulars and the vastness of the data involved put such individuals in impossible positions. They are either guilty of not preventing or of causing various negative outcomes if they are unfortunate or praised for positive outcomes if fortunate. As the author points out in a quote of John Galbraith, "Politics is not the art of the possible. It consists in choosing between the disastrous and the unpalatable (p. 1)."
The key point of the book seems to be that many systems are organized on the critical edge between instability and stability. Life itself may owe its very existence to that fact. Because of this poised-on-the-edge characteristic, small events may cascade in such a way as to produce major changes: a new value for stocks, a massive extinction that creates new opportunities for remaining species, a redistribution of power among nations, etc. Which outcomes occur and when, however, are not subject to predictive formulae, even though they may seem ideally suited to it. If even extreme events are the results of myriads of small, seemingly unimportant events-sort of the butterfly in Japan fluttering its wings concept-then there are no means by which catastrophic events can be predicted any more than smaller ones can be. According to the author, while there seems to be a mathematical frequency with which incidents of different magnitudes occur, there is no way of divining when a specific outcome of a given magnitude will actually occur, nor are the consequences should such an event be forestalled. This has implications for events meaningful to human beings: wars, the stock market peaks and valleys, even extinction events. For Buchanan, history itself may arise by virtue of natural resolutions of unstable systems of whatever kind.
After reading the author's discussion of the Gutenberg-Richter power law and the scale invariance of some systems, it occurred to me that the end of the world scenario presented by Carl Sagan in his book Cosmos-and credited to an earlier researcher-may fall into this category. In that volume, a chart had been created that plotted murder (private war) to the total destruction of mankind against a time line, finding that total annihilation should occur a few years after the year 2000. (It was expected closer to mid 21st century, but the original author had not factored in the destructive power of nuclear war. Later individuals did and produced a chart that suggested armageddon would be around 2010). While the ultimate war may well occur, if Bak and Buchanan are correct, it might not be due to either predictable or controllable factors, and it will probably not occur on any clear cut timetable like that suggested in Cosmos.
An amazingly interesting book full of concepts that, however theoretical, are certainly plausible and explain a lot about our world.
Games Physicists Play.......2002-06-18
Mark Buchanan, however, does away with degrees. As the title of this book implies, all or nothing: Ubiquity is a sole authority. Only my knife cuts potatoes, no knife but mine can cut potatoes. While I agree that the existence of power laws is fascinating, I would not perhaps extend them as far as Buchanan does; I would be more interested in probing why distribution is so regular, rather than insisting that all phenomena must be explained by this, and only this, rule. A power law may signify that a country can be bled, or a forest burned, so far before you run out of fuel. This is more interesting than assuming that because the numbers resemble each other, the conditions necessarily illuminate each other. (As to the power law, please note the comments in Dennis Littrell's review of this book).
I got to the point where I dreaded having to read about yet another game that, amazingly enough, proves the power law (do any games disprove it?). Games seem to go to Buchanan's head, where they practically replace reality, which, needless to say, is far more complex. There are games and there are games, though. On page 126 (paperback version), Newton is praised for simplifying for ease of reasoning; then on page 142, economists are excoriated for simplifying for ease of reasoning. I never thought I would see the day that I stood up for economics, but isn't this a double standard? By the same token, after he so thoroughly debunked the efficient market hypothesis, I was surprised to read on page 188 that after war releases stress, 'each nation is brought back into rough balance with its true economic strength.' But as he says on the next page, 'None of this is meant to be fully convincing.' It's not.
Buchanan at times seems to forget that there is more to human history than wars and revolution, and that great people can change the course of history; where would we be today if George Washington Carver had not saved southern agriculture? Buchanan's total belief in the ubiquity of his games leads him to say something as ridiculous as "the mark of the great scientist lies not so much in having profound ideas that revolutionize science, but in taking ideas ... and making that potential real"(p183). ...limits our reviews to 1,000 words, so I will leave it this sentence for you to explode .
Even if we discount the role anybody but scientists and soldiers play in history, there should be some difference between incipient wars. Consider World War II, in which Germany and Japan geared for widespread conquest, planning meticulously years in advance. The German army would not have rolled through the center of Europe so irresistibly if the Hitler Youth had not trained the young so well; Japanese school children were primed to attack China before the Marco Polo Bridge Incident. Then compare this to the American Revolution, a beef far across the oceans between some (not all) ill-prepared colonists and a Great Britain preoccupied with India. Is it any surprise that WWII spread far and wide, while the American Revolution was fought locally?
I think the author has intriguing ideas, but he has overextended them. Nonetheless, Buchanan's doctrines have a familiar ring. Buddhism long has taught that any event is the result of an infinite number of causes, and the cause of an infinite number of results. The ideas in this book are well worth pondering, but with a grain of salt. One grain. Now, if you have a whole pile of grains of salt, one more might avalanche....

Nanostructures - Fabrication and Analysis (NanoScience and Technology)
Manufacturer: Springer ProductGroup: Book Binding: Hardcover ASIN: 3540375775 |
Product Description
The main theme of this book is the exploration the underlying physical laws that permit the fabrication of nanometer-scale structures. As researchers attempt to fabricate nanometer-scale structures which do not exist per se, they must still employ the natural laws to fabricate them through processes such as self-assembly. So it turns out that our techniques for fabrication of nanometer-scale structures are not artificial but actually rely on the natural laws. We even find that nanometer-scale structures, e.g. fullerenes, are fabricated in nature beneath the surface of the Earth. This fact may be called the ubiquity of the nanometer-scale structures. The topics presented in the book include: scanning probe-related and near-field techniques, nanolithography, self assembling and design of novel nanostructures, as well as new nanodevices and their application.

The Rest of God: Restoring Your Soul by Restoring the Sabbath
Manufacturer: W Publishing Group ProductGroup: Book Binding: Paperback ASIN: B000AOEFLQ |
Product Description
Mark Buchanan's writing always leaves you moved, stimulated, and convicted. You will find yourself mulling it over days later and wishing for more. Most of us feel utterly ransacked: We're waylaid by endless demands and stifling routines. Even our vacations have a panicky, task-like edge to them. "If I only had more time," is the mantra of our age. But is this the real problem? Widle acclaimed author Mark Buchanan states that what we've really lost is "the rest of God-the rest God bestows and, with it, that part of himself we can know only through stillness." Stillness as a virtue is a foreign concept in our society, but there is wisdom in God's own rythm of work and rest. Sabbath is elixir and antidote. It is a gift for our sanity and wholeness-to prolong our lives, to enrich our relationships, to increase our fruitfulness, to make our joy complete. The gift of Sabbath is essential to our full humanity and faith, says Buchanan. here he helps us seek and receive anew the gift of Sabbath, this day of rest and play and replenishment. Far from being some starched and dour day only to be endured, Sabath is a day wide and bright brimming with laughter, enough to lend beauty to all our other days. Readers will be changed forever by this pivotal book.

Theodore Fink: A Talent for Ubiquity
Don Garden Manufacturer: Melbourne University Publishing ProductGroup: Book Binding: Hardcover ASIN: 0522848281 |
Book Description
Theodore Fink was an energetic and controversial public figure in Melbourne from the 1870s to the1940s.Born into a struggling Jewish family, Fink was a solicitor by profession: and a bon vivant and patron of the arts by inclination. He divided his energies between the law, business, newspapers and education. He did not achieve high office, but the reach of his activity and engagement was extraordinary. Thus Don Garden concludes that Fink's chief talent was for ubiquity.
He was a liberal humanist one minute and a scheming opportunist the next. In this engaging biography, Don Garden skilfully maps the many contradictions of an intriguingly complex life.
