Social Geographies of Educational Change

Book Description

Social Geographies, as spatial location, is a factor relevant to understanding the variety of people’s interpretations and appropriations of educational innovations and changes. Their location in the social space also influences their response to change. In the field of educational change, social space means for example, skin colour, gender distribution of teachers in one school, children’s self-cultural representations or parents’ religious attitudes.

By using the notion of Social Geographies in the context of educational change, the authors address the following questions:

How initiatives in a classroom or department are influenced by the surrounding context of the school, the district or the nation;

How innovation spreads or diffuses from one school to another;

How and whether reforms can be scaled up from a few schools to a whole system;

How seemingly standardised reforms affect schools differently depending on where they are located;

How schools influence one another;

How the identities of, and interrelationships among, schools are affected by technology, principles of market competition and choice, and other initiatives.

This volume is relevant to educationalists, policy-makers, teachers, and students interested in a more complex approach to understand and intervene in educational change processes.

Description:
The purpose of the present work is to prepare membranes with specific chelating properties for the removal of metal ions. The semi-interpenetrating polymer network technique was used to prepare tailor-made membranes from blends of poly(vinyl alcohol) with two polyelectrolytes, one with carboxylic groups (poly(acrylic acid)) and one with amine groups poly(ethyleneimine). The 60/40 poly(vinyl alcohol)/polyelectrolyte mass ratio was selected to obtain homogenous membranes with suitable mechanical properties. Gaseous 1,2-dibromoethane, glutaraldehyde and hydrochloric acid were tested as crosslinking agents. A crosslinked poly(vinyl alcohol) membrane was also tested as a reference. The membrane crosslinking was monitored by infrared spectroscopy and swelling measurements. The performances of the membranes were evaluated for the removal of copper (II), cadmium (II), lead (II) and chromium (III) in static experiments. The metal ion absorption efficiency f of the membrane (in %) was calculated from: 100 x [(amount of ions retained by the membrane (mole)]/[(amount of monomer repeat units in the membrane (mole)]. The complexation of Cr(III) was the most efficient at pH = 5 with the poly(vinyl alcohol)/poly(acrylic acid) membrane crosslinked by glutaraldehyde (f = 4.9%). The removal of Cu(II), Cd(II) and Pb(II) was more efficient at pH = 5 with the poly(vinyl alcohol) / poly(ethyleneimine) membrane crosslinked by gaseous 1,2-dibromoethane (f = 5.3, 4.5 and 3.7% respectively). Finally, dynamic experiments were performed in order to simulate the treatment of aqueous solutions. Dynamic experiments at pH = 5 were performed on the DBE-crosslinked PVA/PEI membrane either by flow through a membrane-packed column or by filtration. Using a membrane-packed column, the best result was observed for Cu(II) removal with 40.8% of metal ion uptake, but the system was limited by its high dead volume. With filtration, the best result was observed for Pb(II) removal: the metal ion uptake was 70.0% at the end of the sorption step.

Is the universe perfectly balanced? Physicist Frank Close looks at symmetry and the deep structures of the universe in his luminescent book Lucifer's Legacy. Matter and antimatter, positive and negative charge, even the curious properties of quarks all seem to be arranged in diametrically opposed pairs (or triplets, when you consider zero-state properties like neutral charge). Yet we plainly live in a skewed environment--we can't find antimatter unless we make it, almost all of our proteins are left-handed, and there are 10 Windows machines for every Mac. Is this asymmetry essential for life? Is it, in fact, a necessary consequence of creation? Dr. Close examines these questions and more in intimate but not obsessive detail, showing that life as we know it couldn't exist without a few crucial imbalances.

The question of whether or not we just got lucky with this universe is due to be answered in 2005, when CERN, where Close works, will test theories relating to the Big Bang. The author has a gift for explaining the intricacies of particle physics in terms that lay readers can easily grasp and even come to love. His poetic sensibilities, which frame the book and give it its title (from the statue of Lucifer at the Tuileries gardens in Paris), reflect the human and cosmic mysteries inherent in both the nature of physics and the work of physicists. There's a wee bit of math and geometry herein, but not enough to scare off the numerophobic; in fact, the cogent explanations and illustrations may win Close a few converts to hard science. In the final analysis, Lucifer's Legacy carries a hint of irony: it is such a thoroughly good read that you'll find yourself hunting in vain for flaws. --Rob Lightner

Book Description

Modern scientific theory describes a uniformly perfect creation; a universe in which matter would have been destroyed within an instant of its appearance and where nothing that we now know could ever have happened. Human life itself seems lopsided, as the spherical embryo is transformed into a highly structured being with its internal organs mirror asymmetric. The molecules of life differ from their mirror images: the milk in Alice's looking glass would not have been fit to drink. The mystery of how nature produces structured asymmetric patterns from an underlying uniformity is the focus of much current scientific research. In Lucifer's Legacy, physicist and broadcaster Frank Close explores the origins of asymmetry from life to the Universe at large, and asks whether this multitude of examples can be traced back to a single act that took place at the origin of our Universe. Inspired by a chance meeting with Lucifer in the Tuillerie gardens in Paris, Close takes the reader on a sweeping tour of asymmetry in the world around us, from the development of human embryos to the mysterious Higgs boson. His tour culminates in the research now underway in Switzerland, where scientists are preparing an experiment to recreate the Big Bang and hope to resolve the mystery of original asymmetry. Lucifer's Legacy describes the possible outcomes of this experiment, and assesses their implications for our understanding of the universe.

A wonderful first look at physics.......2002-06-27

This book is a pleasant, painless introduction to particle physics and the applications of symmetry in the universe. I could see how it might annoy an experienced physicist with entire chapters full of metaphors and analogies intended to solidify the reader's understanding of the concepts, but for a beginner these are quite helpful. It also includes a long and detailed history of the major discoveries in atomic physics, which is a tiny bit too long, but still informative and well written. I am a junior in high school, and I enjoyed this book immensely.

For laymen only.......2002-06-05

Before I start to criticise "Lucifer's Legacy", I should add that I am a trained physicist, and wanted to brush up a bit about ideas of symmetry/asymmetry, which have become essential to our quest to explain the physics of the universe. Having clarified this, I must say the first part of this book was a real disappointment: it seems to be intended for people who have not heard much about physics since they left high school. There are some nice detours about the history of physics about the turn of the century. But apart from that, the book often is annoyingly trivial. Towards the end it gets more interesting, and some ideas about symmetry and symmetry breaking are nicely presented. But if you look for more than light bedtime reading, look somewhere else.

Great Book - Collector's Item?.......2002-01-11

The book is extremely well written, fascinating, and easy to read. But the best part is the little errata sheet that comes with the book that may make it a collector's item. There is a drawing in the book of the Tullieries Garden in Paris meant to show the symmetry humans wish to achieve. The drawing has an error that breaks the symmetry, just like the one headless Lucifer statue in the Garden broke the symmetry when the author visited it, giving him a starting point for this book. The errata sheet attempts to restore the symmetry with a new drawing, but the irony has already made its point; human attempts at symmetry are doomed to fail in an asymmetric universe.

Breaking the Balances.......2000-12-13

The world is full of symmetries, broken and unbroken, according to _Lucifer's Legacy: The Meaning of Asymmetry_ (Oxford University Press) by Frank Close. It may be that disrupted symmetries are essential for our very being, and experiments planned for this decade may give us an answer about this. The world of subatomic particles and basic forces is very weird, and so Close spends much of his book discussing symmetries that are a bit easier to understand. For instance, human bodies are mostly symmetric on the outside, but there are interesting exceptions to this rule. Some molecules come in left and right handed forms, and our own molecules are of the left form, as are most biological molecules. (It makes a difference; the molecule limone comes in right and left forms, too, and we can tell the difference: one smells like lemons and one like oranges.) Close tells us why mirrors reverse right and left but not up and down (they don't, really) and why bathtubs drain in different directions in different hemispheres (they don't, really).

Symmetry can break up for all sorts of reasons. Billions of years ago in the Big Bang, for instance, there was equal matter and antimatter. For some reason, as far as we know, matter prevailed. Why? Are there packets of antimatter galaxies in the universe that are buffered from us by light years of separation? How did the asymmetric increase of matter over antimatter come to be? Why is there more matter, and when it comes down to it, why is there anything?

These are questions that the newest generation of particle accelerators will be trying to tackle in the next decade. Close's book does a good job of examining these confusing issues and trying to make some sort of sense of them for the layman. He has a gift for the felicitous metaphor, and his writing on strange subjects is clear.

Reason for the existence of life to elementary particles.......2000-08-27

The author beautifully narrates to laypersons how broken symmetry, i.e., asymmetry born from symmetry is important in the natural world for the existence of life, molecules, atoms and elementary particles. The riddle of the symmetry associated with the last of these items when the universe was created is yet to be solved in the near future. At the end of the book, the reader will be surprised to learn that Pasteur anticipated the importance of asymmetry in 1860. In an early chapter the author writes about the moderately well-known teaser "Why do mirrors reverse left and right but not top and bottom?" His answer to this is astonishingly simple. However, he should have been careful to give a more educational answer that includes the explanation for the reversal of the left- and right-handedness in mirrors, because he describes about "mirror asymmetric" left-handed and right-handed molecules, right-handedness of DNA and left-handedness of "the mirror DNA," etc. in a later chapter. [The latest academic articles on the mirror reversal problem can be found in M. C. Corballis, Psychonomic Bulletin & Review Vol. 7, No. 1, pp. 163-169 (2000) and T. Tabata and S. Okuda, ibid. pp. 170-173 (2000).] This book would also be interesting for scientists to learn how they can talk well about scientific topics to laypersons. It would have been much better for the book to include a bibliography for citations and further reading.

Customer Reviews:

Not tonight, I've got a headache.......2007-06-26

The only good thing I can say is that once you've read one of the sexual encounters (please, let's not call them love scenes)in any of the books in this series, you can skip ahead 20 pages or so and not miss any of the so-called plot. If you crave sensuality, try the Merry Gentry or Antia Blake series.

Unfortunately.......2007-01-06

I'm a fan of the Dark series Ms. Feehan has written. Unfortunately, I'm just going to be blunt and say that this book bored me. It's almost as if she was bored herself writing this book. I got it sometime last year, got through half of it and haven't finished it yet, and I've never done that with a book in my entire life. This is something I would not suggest for anyone to buy.

Not one of the best in the series.......2007-01-03

but still a good read. A good stand alone book because it is really only focuses on the two main leads, not the other's in the series

Ugh, not again, Feehan.......2006-08-05

I hate this - some Dark books take my breath away, and some... well, they just make me want to yack.

As of now, only two have accomplished such a feat; 'Dark Gold' was atrocious, and I had to put it down within five chapters else risking to lose my Beaner's short Teddy Bear.

'Dark Symphony' was the same way, unfortunately. Byron annoyed me in 'Dark Desire' (go Jacques, you sexy beast) and he did nothing for me now. Antoinetta made my back teeth grind.

I don't know, maybe it's because Byron and Aidan are blonde. Then again, so was Julian and I loved his story. But he had Desari, whom I thoroughly enjoyed.

Definitely must be the blonde factor. I like my protagonist men brunette.

thoroughly enjoyed.......2006-07-31

I enjoyed this book in the dark series. there was lots of action and romance. it was hard to put the book down.

Book Description

Una terrible amenaza se cierne sobre Antonietta Scarletti, famosa compositora y heredera de una enorme fortuna. Ciega desde los cinco años, sólo encuentra seguridad en Byron, el extraño personaje que desde hace unos días frecuenta su palacio. No puede verle, pero sabe que es mucho más que un hombre normal: puede leer sus pensamientos, posee una fuerza sobrehumana..., aunque lo más sobrenatural en él es la abrasadora pasión que despierta en ella cada vez que están cerca. Antonietta acepta entrar en el extraño mundo de Byron y los de su especie, la fabulosa raza de los Carpatianos, pero antes los dos deberán utilizar todas sus habilidades para hacer frente al peligro que les rodea.

UN SER LEGENDARIO ...
Los Carpatianos están en este mundo desde el inicio de los tiempos. Cazadores implacables de vampiros, son como ellos seres de la noche, capaces de cambiar de forma, de leer la mente y de otras sorprendentes habilidades. Byron Justicano es uno de los más poderosos que existen en su especie, pero no está exento de debilidades humanas: un terrible remordimiento le condena a vagar solo, alejado de los que son como él. Hasta que un día escucha una melodía embriagadora, y sabe que ha descubierto a su compañera. La mujer que está sentada al piano se convierte en la razón misma de su existencia, y para protegerla está dispuesto a utilizar todo su poder.

...SÓLO PODÍA ELEGIR UNA MUJER COMO ELLA
Antonietta vive en un mundo de lujo y a la vez sumida en las tinieblas, desde que perdió la vista a los cinco años. Sin embargo, posee una gran intuición, casi un poder psíquico, que le permite manejarse en su carrera y en su complicada familia. Quizás ese mismo don le ha permitido intuir que aquel hombre extraño que aparece de pronto en su habitación no es un ser como los demás. Un desconocido hacia el que cualquiera sentiría desconfianza e incluso terror, pero que en ella despierta un intenso deseo y el íntimo conocimiento de que, de alguna manera, está predestinada a ser suya.
