It's interesting how networks, computer systems, and software applications have evolved towards the notion of information services. The industry is looking at information technology in terms of services provided for business operations, and that has caused interest in buying, deploying, and managing services instead of networks and applications.

This book is a buyer's guide into the numerous products that manage services in one way or the other. The first 50 pages are devoted to concepts in service level management, while the remaining 300 or so pages describe some 70 SLM solutions along several dimensions, including product functionality, distinguishing features, data sources, third-party product reliance, support for service-related standards, pricing/packaging, and strengths/weaknesses. I would think that readers would study the first 50 pages carefully and use the product description section as a reference. The 50 page overview is excellent, from both a technical and business point of view.

I almost gave the book four stars because it is inevitable that SLM vendors with change their products, some will go out of business, and new ones will come into play, and thus the book would become obsolete in relative short order. However, the very last page of the book promises a 2nd edition. A book of this sort should probably be updated annually.

Also, I almost gave the book 4 stars because it has no references to other sources. But section 2 refers to several SLM standards bodies and lists URLs, including ITIL, Telemanagement Forum, and IEFT.

There was just one thing about the book that puzzled me: In the table of contents, about a dozen of the 70 companies are in bold, and I couldn't figure out why. However, that problem wasn't worth taking off a star.

In sum, the book is perfect for businesses comtemplating SLM expenditures. I would expect to see it updated from time to time to keep up with the industry.

The analysts at EMA have written a very clear guide to helping IT people prepare for, evaluate and compare, and implement an SLM solution. The book is divided into two parts. The first part is a detailed discussion of the important facets of Service Level Management: what it is, all of the things that it encompasses, how to create and negotiate SLAs (Service Level Agreements), creating RFPs to evaluate SLM offerings, and some of the nitty-gritty around the actual measurements. The second part is a synopsis of the majority of commercial software products available for SLM. Each vendor gets a four or five page write-up that summarizes key features, the pricing model, expected support costs, and a brief EMA summary of the product and company, including strengths and limitations. If you need to implement an SLM solution, don't expect to find all of your questions answered just by looking at the product comparisons. Chapters 3 and 4 provide a wealth of information about how to evaluate solutions based on your specific environment and then how to write the RFP so that you will get the information to meet your specific needs. The one thing that is missing from the Vendor Briefs is any mention of open source software. In some cases, open source solutions my provide a better fit than COTS (Commercial Off The Shelf) software products at a somewhat lower price point. Regardless of the direction chosen (commercial or open source), the information in "SLM Solutions: A Buyer's Guide" will provide the reader with important information about the whole SLM process.

Great resource for anyone trying to implement SLM. A must have
that lists (what seems like) every vendor's product with an honest
evaluation of the strengths and weaknesses of each. Every IT professional should have a copy on his/her bookshelf.

The photos in this book are gorgeous. There's some sublime shots of stalagmite/stalagtite formations in the Devil's Womb, and a stunning two page montage of an iron ore skein in Deep Green Cave. There's also photos of the wildlife you get in the caves - bats, crabs and blind moles, and a couple of cracking shots of some chutney ferrets down in the darkest recesses of Kak Canyon. I *love* this book.

A most enjoyable and informative read, for the "professional" caver, the new spelunker, or the armchair sort (me!) who's just curious about caving!

Beautiful pictures!

I read the entire book in a day and it was time well spent!

In Colorado Caves: Hidden Worlds Beneath The Peaks, Richard Rhinehart examines the exploration, history, science, and conservation of Colorado's fabulous caves. The informative and engaging text is profusely illustrated with the outstanding color photography of David Harris, and includes some b/w historical photographs as well. Well suited for the tourist or spelunker, there are listings of Colorado caves that can be visited by the general public. Whether an armchair traveler or a dedicated cave exploration enthusiast, Colorado Caves is very highly recommended reading!

The theory of schemes is usually thought to be highly abstract and esoteric, and one that makes the study of algebraic geometry even more difficult. The authors definitely dispel this notion in this book, which could have been called "A Concrete Introduction to Schemes", because of the clarity with which the concepts are introduced and explained. After studying this book, one will understand and appreciate the power of schemes in algebraic geometry. The authors do an even better job than they did in their earlier and short work "Schemes: The Language of Modern Algebraic Geometry", which is now out of print.

In chapter 1, the main definitions are given and the basic concepts behind schemes outlined. That schemes are more complicated than varieties is readily apparent even in this beginning chapter, where they are thought of as corresponding to the spectrum of a commutative ring with identity. Very elementary exercises are given to help the reader gain confidence in the constructions involved. They authors do have to discuss some sheaf theory, but they show its relevance nicely in this chapter. They also discuss the notion of a fibered product as a generalization of the idea of a preimage of a set under the application of a function and relate it to the construction of the functor of points. The role of the functor of points as reducing schemes to a kind of set theory is brought out beautifully here.

The next chapter gives many examples of schemes, with the first examples being reduced schemes over algebraically closed fields, these being essentially the ordinary varieties of classical algebraic geometry. The authors then give examples of schemes, the local schemes, which are more general than varieties. When departing from the assumption of a field that is not finitely generated, extra points will have to be added to classical varieties. The fact that only one closed point appears is compared to the case of complex manifolds, via the concept of a germ. This is a very helpful comparison, and one that further solidifies the understanding of a scheme in the mind of the reader. The authors give the reader a short peek at the etale topology in one of the examples. Examples are then given where the field is not algebraically closed, generalizing classical number theory, and non-reduced schemes, where nilpotents are present. The chapter ends with examples of arithmetic schemes where the spectra of rings are finitely generated over the integers.

Projective schemes are the subject of Chapter 3, and are defined in terms of graded algebras and invariants of projective schemes embedded in projective space are discussed. The Grasmannian scheme is discussed in detail as an example of a projective scheme. Interestingly, Bezout's theorem, very familiar from elementary algebraic geometry, is generalized here to projective schemes.

Constructions from classical algebraic geometry are generalized to schemes in Chapter 4. The first one discussed is the notion of a flex, which deals (classically) with the locus of tangent lines to a variety. The flexes are defined in terms of the Hessian of the variety, the latter being generalized by the authors to define a scheme of flexes. The notion of blowing up is also generalized to the scheme setting, with the authors motivating the discussion by blowing up the plane. The discussion of blow-ups along non-reduced subschemes of a scheme and blow-ups of arithmetic schemes is fascinating and the presentation is crystal clear. Fano varieties are also generalized to Fano schemes in the chapter. Most of the information about these schemes are contained in the exercises, and some of these need to be worked out for a thorough understanding.

The next chapter is more categorical in nature, and deals with generalizations of the classical Sylvester construction of resultants and discriminants to the scheme setting.

In the last chapter the authors return to the functor of points, and motivate the discussion by asking for a parametrization of families of schemes. The authors show, interestingly, that using the functor of points one can more easily compute geometric information about a scheme than using its equations. They illustrate this for the Zariski tangent space. Then after an overview of Hilbert schemes they close the book by introducing the reader to moduli spaces and a hint of algebraic stacks. No end in sight for this beautiful subject..........

This book is clear, well written, and has a nice balance of generalities and examples. If you know the basics of rings and modules, this book will show you what schemes are and why they are useful for several different problems: for example, number theory, or studying singularities. I find it a helpful companion to Hartshorne's ALGEBRAIC GEOMETRY. But this book does not get to cohomology, and so cannot actually get to the working methods in the subject. For that, you need Hartshorne.

Very good book for scheme theoritical approach to Algebraic Geometry

Payback is the first book I have ever read cover to cover where I haven't wanted to miss a word! Each page left me needing to know wich direction Todd Black's gripping life was going to turn next. Payback is a strongly written tale of adversity and justice which left me wanting to pick it up for a second read. I highly recommend this fast pace novel for all.

This is most certainly one of the best books I have ever read in my entire life. The chilling detail used by the author entice the reader to forget their life, job, family, pet, everything, and keep reading and reading. I even found myself reading the book a second time, something I have never done before. If you are into realism and being shocked, buy this book, its incredible.

Payback comes accross as an easily read novel, that not only entises the reader to continue turning each page but draws you in to feeling for Mr. Todd Black, almost craving the sweet revenge for him and yourself. The incorporation of street lifestyles of the young Black and his peers compliments the novel and allows the reader to associate their own lifestyles (0r possibly they're past) and to see how the possible reality of this could eventuate, pulling you deeper into the phsyche of the infamous avenger. Payback is a novel that once you pick up - is hard to put back down, until all the wrath is dealt out! A novel that will entertain and captivate many a reader. This book kicks it in the zone!

This book sits rather oddly with others in the Institute of Economic Affairs Choice in Welfare Series. Whilst the sub-title 'Welfare before the Welfare State' suggests that this is an account of self-help swept away by the state the content is more contested arguing that the self-help which was available was confined to the skilled and semi-skilled working class rather than to all of the working classes at the time. This point of view is not particularly challenged, a fact which, given the genesis of the project, is surprising to say the least.

Before Beveridge is a welcome addition to the literature about welfare before the state intervened in Britain. Contrary to the establishment history books which used to argue that the benevolent state stepped into a welfare vacuum, a number of studies have challenged this claim with books and scholarly articles demonstrating that the working classes were more than capable of providing education and welfare for their families by themselves as individuals and in groups long before the administrative machine moved in.

In this slim volume it seems that the editor and the staff at the IEA Health and Welfare Unit have rather abdicated the case for individual enterprise in welfare provision to those authors who put forward the view that in reality this provision was available to a select number of the working classes and the unorganised and the poor were not able to avail themselves of the opportunity. The so-called liberals appear to stand aside in the face of the attack and do not attempt to join battle with those propositions. I find the papers of Whiteside, Harris, Vincent and Thane to be particularly well researched and argued as well as persuasive given the paucity of David Green's paper especially.

The weakness of the writers who suggest that there was indeed a need for the intervention of the state in bringing welfare provision to the neediest in British society is the determination to overlook the evidence that many of the disenfranchised working classes who did not belong to either friendly societies or trades unions were determined to provide education for their children regardless of their personal circumstances. The fact that individuals of limited means were capable of identifying, by themselves, often without any education of their own, options for the betterment of their children over the longer term and were prepared to forego current onsumption to pay for it speaks volumes which significantly undermines the position supporting the need for state involvement.

This is a very thought provoking book which adds substantially to the lierature and which colours the debate about welfare provision more vividly than before. I would heartily recommend the book to sixth form and college students of history and social policy as well as practitioners of the black arts of social policy and policy-makers in general.

Charles Calhoun's MAINE is a departure from most travel guides. Rather than just pages and pages of lists of motels, restaurants, and things to see, Calhoun focuses on the state's people (past and present), natural history, and state-of-mind. Instead of simply an address and phone number for the famous L. L. Bean's (outdoor outfitters, for example, Calhoun gives us several pages, including the story of the founder of the company.

The book opens with a chapter entitled "Learning Maine" and is organized geographically into nine main sections which cover the entire state. The final chapter, "Practical Information" gives all the usual, plus "A Dozen Fun Places to Eat" and antiquarian booksellers. Scattered throughout the book are literary excerpts and topical essays by authors such as May Sarton, John McPhee, and Longfellow. There are maps, reproductions of period art, and plenty of gorgeous color photos. Whether the reader is planning a trip to Maine or merely wishes an intriguing armchair journey, this guide is a must.

Kimberly Borrowdale, Under the Covers Book Reviews

An excellent book to take along with you during your travels to Maine. The photos in this book are simply beautiful! The photographer, Thomas Mark Szelog actually lives in the lighthouse on the cover!! I was lucky enough to meet him and he was kind enough to show me some of his photgraphs. Absolutely beautiful work. This is a great book and I highly recommend it when you travel down east!

An outstanding book, sophisticated and intellectual but absolutely charming. Definitely a solid approach to inspiring children. Kudos to Carolyn Spencer!

I loved these stories growing up and missed them when I started reading to my sons. I'm glad they are still around. Lessons are hidden in many of the stories, but not as blatent as many new childrens books seem to be.

Great stuff. Came with a poster, too!

If you're thinking of buying this to be AFRICAN lore, don't. This is an adaptation of the Joel Chandler Harris Uncle Remus stories, focusing on those containing the Brer Rabbit character. The stories are delightful, and will be a joy to any (I also heartily recommend buying a complete set for reading aloud), but the tales are drawn directly from the heart and soul of America (there are no raccoons and bears in Africa, anyway...sheesh).

After visiting Disney World last year my 4 year old daughter kept after me to retell the story of Brer Rabbit and the tar baby, I was so pleased to find this book with its great illustrations. When we read this book before bed we just can't read one. My daughter likes all the stories not just the Tar Baby and the poster is great too.

This Eyewithness book is up-to-date and very practical. It contains a lot of pictures which is extremely usefull if you are planning a trip. When planning the trip it makes the book in a way easier to use than for example the Lonely Planet of Boston since you got a clear picture of the surroundings.

I live in New England and this is another of my favorite books from this region of the country. DK has always published quality books in their Eyewitness Travel Guides and they have done an excellent job with this volume on Boston. Unless you visit Boston on a frequent basis it is easy to get disoriented. I really found this book quite useful and the colorful layout of this book with maps, illustrations, photographs and text really inspired me to delve into its pages and check out one of New England's premier cities. The historical information on Boston was invaluable. I never realized some of the things I used to walk past. I think it is also very informative, not only from a historical perspective, but also as a point of reference for sightseeing, travel and enjoyment.

The Eyewitness Travel Guide to Boston was recommended to me in a bookstore and it was perfect for a recent 5-day trip to Boston. The guide is laid out by area, so you really get a feel for what else is around you when you are at a particular destination. The overall maps are very good and well detailed and the book is chock full of great photos. It also includes great history and background info. My Boston friend kept asking me "how do you know all this stuff?"

This book is a long overdue explanation of the "Logical Effort" approach to MOS circuit design invented by two of the authors, Sutherland and Sproull, in the late 80's. The technique presented is complete and powerful, and this book should be required reading for all persons involved in high-performance or low-power MOS digital design. Nevertheless, I would not recommend it for beginners without some of what the authors call "instruction from veteran designers." The main shortcoming of the book is a lack of organization---important points are sometimes made in seemingly unrelated sections, and the sections themselves do not always appear to follow the most logical arrangement---and it could stand a more thorough editing job to clean up some of the presentation. Sometimes, I felt that information that was presented in charts would have been much more powerful in graph form. A few of the graphs in the book are misleading (arbitrary scales and unmarked breaks in scales), and some of the mathematical terminology is imprecise. The fact that the authors picked, somewhat arbitrarily, a new definition of the technology delay parameter tau (instead of sticking to the definition established by Mead & Conway in their 1980 book) is annoying. Aspiring asynchronous designers should be cautioned that the two designs for an n-input Muller C-element contrasted in Section 11.2 are logically different. A section contrasting the uses of the logical effort method in synchronous and asynchronous designs would also be welcome. All in all, however, the book is very readable, and it is easy to follow. It would be effective as a textbook, and it is a most welcome addition to my library because it treats a difficult and important topic better and in more detail than any other published work.

This is without a doubt a must-have for CMOS logic and circuit designers. No doubt this will be on my desk for the forseeable future. The first two chapters present a basic introduction to the approach that is sufficient to gain a working knowledge. The remaining chapters delve into details such as applying the method to domino circuits, passgate logic, cells with unequal rise/fall times, and a complete derivation of the method. The authors are well known experts in the field of high speed circuit design, and David Harris' presentation of the material is far from bland and boring. This is one of the few technical books I had a hard time putting down. Highly recommended!

A welcome addition to the field of VLSI with pratical and not ridiculous constraints to establish fast and efficient logic designs. The book could use some introduction topics in VLSI to make the book more broad and probably more appealing as a textbook.
