Book Description
Life, love, and the pursuit of the perfect Englishman… Emily Williams, twenty-something free spirit, is spending a year in England with — horror of horrors — her parents. She’s not going to let that get her down, though…any more than she is brought low by her seemingly hopeless search for love, the ghost that inhabits her underwear drawer, the horrible high school flashbacks that come via a student she tutors, the hot guy she fancies who may or may not be what he appears, or the dishy almost-veterinarian who could be the perfect Mr. Emily…if only he wasn’t elbow-deep in sheep. Literally.. Welcome to the world of Emily! EMSTER What, you’re not here? DRU I’m here. What’s up, buttercup? EMSTER I have things to tell you! DRU So tell. I was sext…er…texting the BF. EMSTER !!! DRU J/K. Dish, sister. EMSTER Reasons why my life has gone to hell in a handbasket: In debt up to my armpits due to having to work off paying for ex-boss’s car. DRU Shouldn’t have hit that cop car, huh? EMSTER Forced to give up adorable apartment to live back with the parents while I pay off ex-boss’ car. DRU Also shouldn’t have lipped off to the judge who garnished your wages. EMSTER Forced to go with very same parents to England for a year. DRU Dude. EMSTER OK, that’s not really bad, but I’m on a roll. Humor me. EMSTER Biggest reason life is messed up: Friends with Benefits Fang isn’t around to indulge in benefitting. DRU You got me there. But cheer up, little Emily – life can’t get any worse can it? Readers of the 2003 release The Year My Life Went Down the Loo may recognize passages–this book is an almost complete rewrite and update of that earlier young adult novel, and contains mature themes.

Book Description
What people are saying about Search Patterns "Search Patterns is a delight to read -- very thoughtful and thought provoking. It's the most comprehensive survey of designing effective search experiences I've seen." --Irene Au, Director of User Experience, Google "I love this book! Thanks to Peter and Jeffery, I now know that search (yes, boring old yucky who cares search) is one of the coolest ways around of looking at the world." --Dan Roam, author, The Back of the Napkin (Portfolio Hardcover) "Search Patterns is a playful guide to the practical concerns of search interface design. It contains a bonanza of screenshots and illustrations that capture the best of today's design practices and presents a fresh perspective on the broader role of search and discovery." --Marti Hearst, Professor, UC Berkeley and author, Search User Interfaces (Cambridge University Press) "It's not often I come across a book that asks profound questions about a fundamental human activity, and then proceeds to answer those questions with practical observations and suggestions. Search Patterns is an expedition into the heart of the web and human cognition, and for me it was a delightful journey that delivered scores of insights." --Dave Gray, Founder and Chairman, XPLANE "Search is swiftly transforming everything we know, yet people don't understand how mavens design search: by stacking breadcrumbs, scenting widgets, and keeping eyeballs on the engine. I urge you to put your eyeballs on this unique and important book." --Bruce Sterling, Writer, Futurist, and Co-Founder, The Electronic Frontier Foundation "As one who searches a lot (and often ends up frustrated), Search Patterns is a revelation." --Nigel Holmes, Designer, Theorist, and Principal, Explanation Graphics "Search Patterns is a fabulous must-have book! Inside, you'll learn the whys and wheres of practically every modern search design trick and technique." --Jared Spool, CEO and Founder, User Interface Engineering Search is among the most disruptive innovations of our time. It influences what we buy and where we go. It shapes how we learn and what we believe. In this provocative and inspiring book, you'll explore design patterns that apply across the categories of web, ecommerce, enterprise, desktop, mobile, social, and real-time search and discovery. Filled with colorful illustrations and examples, Search Patterns brings modern information retrieval to life, covering such diverse topics as relevance, faceted navigation, multi-touch, personalization, visualization, multi-sensory search, and augmented reality. By drawing on their own experience-as well as best practices and evidence-based research-the authors not only offer a practical guide to help you build effective search applications, they also challenge you to imagine the future of discovery. You'll find Search Patterns intriguing and invaluable, whether you're a web practitioner, mobile designer, search entrepreneur, or just interested in the topic. Discover a pattern language for search that embraces user psychology and behavior, information architecture, interaction design, and emerging technology Boost enterprise efficiency and e-commerce sales Enable mobile users to achieve goals, complete tasks, and find what they need Drive design innovation for search interfaces and applications

Transformational Change Efforts: Student Engagement in Mathematics through an Institutional Network for Active Learning
Author: Wendy M. Smith
Publisher: American Mathematical Soc.
ISBN: 1470463776
Category : Education
Languages : en
Pages : 372
Book Description
The purpose of this handbook is to help launch institutional transformations in mathematics departments to improve student success. We report findings from the Student Engagement in Mathematics through an Institutional Network for Active Learning (SEMINAL) study. SEMINAL's purpose is to help change agents, those looking to (or currently attempting to) enact change within mathematics departments and beyond—trying to reform the instruction of their lower division mathematics courses in order to promote high achievement for all students. SEMINAL specifically studies the change mechanisms that allow postsecondary institutions to incorporate and sustain active learning in Precalculus to Calculus 2 learning environments. Out of the approximately 2.5 million students enrolled in collegiate mathematics courses each year, over 90% are enrolled in Precalculus to Calculus 2 courses. Forty-four percent of mathematics departments think active learning mathematics strategies are important for Precalculus to Calculus 2 courses, but only 15 percnt state that they are very successful at implementing them. Therefore, insights into the following research question will help with institutional transformations: What conditions, strategies, interventions and actions at the departmental and classroom levels contribute to the initiation, implementation, and institutional sustainability of active learning in the undergraduate calculus sequence (Precalculus to Calculus 2) across varied institutions?

Nine Unlikely Tales
Author: Edith Nesbit
Publisher: Library of Alexandria
ISBN: 1465604022
Category : Fiction
Languages : en
Pages : 224
Book Description
A great many kings who were not at all respectable would have given their royal ears to be allowed to send their daughters to this school, but Miss Fitzroy Robinson was very firm about references, and the consequence was that all the really high-class kings were only too pleased to be permitted to pay ten thousand pounds a year for their daughtersÕ education. And so Miss Fitzroy Robinson was able to lay aside a few pounds as a provision for her old age. And all the money she saved was invested in land. Only one monarch refused to send his daughter to Miss Fitzroy Robinson, on the ground that so cheap a school could not be a really select one, and it was found out afterwards that his references were not at all satisfactory. There were only six boarders, and of course the best masters were engaged to teach the royal pupils everything which their parents wished them to learn, and as the girls were never asked to do lessons except when they felt quite inclined, they all said it was the nicest school in the world, and cried at the very thought of being taken away. Thus it happened that the six pupils were quite grown up and were just becoming parlour boarders when events began to occur. Princess Daisy, the daughter of King Fortunatus, the ruling sovereign, was the only little girl in the school. Now it was when she had been at school about a year, that a ring came at the front door-bell, and the maid-servant came to the schoolroom with a visiting card held in the corner of her apronÑfor her hands were wet because it was washing-day. ÒA gentleman to see you, Miss,Ó she said; and Miss Fitzroy Robinson was quite fluttered because she thought it might be a respectable monarch, with a daughter who wanted teaching. But when she looked at the card she left off fluttering, and said, ÒDear me!Ó under her breath, because she was very genteel. If she had been vulgar like some of us she would have said ÒBother!Ó and if she had been more vulgar than, I hope, any of us are, she might have said ÒDrat the man!Ó The card was large and shiny and had gold letters on it.

Pages : 360
Book Description
The $3x+1$ problem, or Collatz problem, concerns the following seemingly innocent arithmetic procedure applied to integers: If an integer $x$ is odd then “multiply by three and add one”, while if it is even then “divide by two”. The $3x+1$ problem asks whether, starting from any positive integer, repeating this procedure over and over will eventually reach the number 1. Despite its simple appearance, this problem is unsolved. Generalizations of the problem are known to be undecidable, and the problem itself is believed to be extraordinarily difficult. This book reports on what is known on this problem. It consists of a collection of papers, which can be read independently of each other. The book begins with two introductory papers, one giving an overview and current status, and the second giving history and basic results on the problem. These are followed by three survey papers on the problem, relating it to number theory and dynamical systems, to Markov chains and ergodic theory, and to logic and the theory of computation. The next paper presents results on probabilistic models for behavior of the iteration. This is followed by a paper giving the latest computational results on the problem, which verify its truth for $x < 5.4 cdot 10^{18}$. The book also reprints six early papers on the problem and related questions, by L. Collatz, J. H. Conway, H. S. M. Coxeter, C. J. Everett, and R. K. Guy, each with editorial commentary. The book concludes with an annotated bibliography of work on the problem up to the year 2000.
