    She attended school against her parents' wishes. Despite her intellectual curiosity, she consistently failed her subjects because she couldn't keep up with the fast-paced, competitive, shame-inducing educational style.Flunking her 10th-grade finals just about extinguished her academic hopes. But one act of kindness radically changed her trajectory when an inspired acquaintance convinced her to redo the grade. Her new teacher--who was passionate and caring--taught students instead of subjects. A friend from her church gave her the finest tutoring, much-needed friendship, and even an example of a loving home and family.After completing 10th grade with top marks, she spent her remaining school years working tirelessly, eventually earning the Best All-Round Student award. Her passion for learning expanded into a passion for teaching; she pursued post-secondary degrees in America and began an influential career as a professor of education and international education consultant.Hong's eloquent present-tense narration animates scenes of family strife and academic struggle and evokes an astounding range of emotions--commiseration, frustration, and eventually elation. Something is always developing, whether it's the narrator herself or the plot.Though the memoir charts the author's intellectual growth, it also considers complex family relationships, poverty, Southeast Asian culture and education, disability, and determination. Hong demonstrates, through her own experiences, the pleasures and rewards of scholarship and effective teaching, and her account underscores how ordinary people can have life-changing effects on others.DescriptionWhen people first meet Barbara Hong, they often conclude that her life must have always been enriched. They assume she had loving, successful parents and all the support she needed to reach her goals. Nothing could be further from the truth.Hong's path to an Ivy League university and beyond started in a filthy tenement in Singapore where she lived with an abusive father and an illiterate mother. Even as a child of six, she worked in her sweatshop home to help with extra money, which her father often wasted on alcohol. As she endured his drinking and abuse, she feared that the pain she internalized could shatter her.But instead of falling apart, Hong managed to escape her misery, thanks to a teacher who believed in her. Once she knew she wasn't the brainless "cabbage head" her mother called her, she began excelling as a student, eventually finding the courage to leave her home and discover her true calling as a knowledge seeker, educator, and advocate.Hong's inspirational journey from a sweatshop home upbringing to influential professor movingly illustrates the true strength of the human spirit and the power of teachers.Failing UP was recognized as one of only 2% of books reviewed to earn a Kirkus STAR--the most prestigious designation in the book industry in awarding books of exceptional merit.

    For the first time, William Poundstone reveals the toughest questions used at Microsoft and other Fortune 500 companies -- and supplies the answers. He traces the rise and controversial fall of employer-mandated IQ tests, the peculiar obsessions of Bill Gates (who plays jigsaw puzzles as a competitive sport), the sadistic mind games of Wall Street (which reportedly led one job seeker to smash a forty-third-story window), and the bizarre excesses of today's hiring managers (who may start off your interview with a box of Legos or a game of virtual Russian roulette). How Would You Move Mount Fuji? is an indispensable book for anyone in business. Managers seeking the most talented employees will learn to incorporate puzzle interviews in their search for the top candidates. Job seekers will discover how to tackle even the most brain-busting questions, and gain the advantage that could win the job of a lifetime. And anyone who has ever dreamed of going up against the best minds in business may discover that these puzzles are simply a lot of fun. Why are beer cans tapered on the end, anyway?

    This book points out the many ways, some quite subtle and deceptive, that this mindset invites tension and conflict. But incredible things happen when people switch to an outward mindset. They intuitively understand what coworkers, colleagues, family, and friends need to be successful and happy. Their organizations thrive, and astonishingly, by focusing on others they become happier and more successful themselves! This new mindset brings about deep and far-reaching changes. The Outward Mindset presents compelling true stories to illustrate the gaps that individuals and organizations typically experience between their actual inward mindsets and their needed outward mindsets. And it provides simple yet profound guidance and tools to help bridge this mindset gap. This new edition includes a new preface, updated case studies, and new material covering Arbinger's latest research on mindsets. In the long run, changing negative behavior without changing one's mindset doesn't last—the old behaviors always reassert themselves. But changing the mindset that causes the behavior changes everything.

    This book describes BEAM✲, an agile approach to dimensional modeling, for improving communication between data warehouse designers, BI stakeholders and the whole DW/BI development team. BEAM✲ provides tools and techniques that will encourage DW/BI designers and developers to move away from their keyboards and entity relationship based tools and model interactively with their colleagues. The result is everyone thinks dimensionally from the outset! Developers understand how to efficiently implement dimensional modeling solutions. Business stakeholders feel ownership of the data warehouse they have created, and can already imagine how they will use it to answer their business questions. Within this book, you will learn: ✲ Agile dimensional modeling using Business Event Analysis & Modeling (BEAM✲) ✲ Modelstorming: data modeling that is quicker, more inclusive, more productive, and frankly more fun! ✲ Telling dimensional data stories using the 7Ws (who, what, when, where, how many, why and how) ✲ Modeling by example not abstraction; using data story themes, not crow's feet, to describe detail ✲ Storyboarding the data warehouse to discover conformed dimensions and plan iterative development ✲ Visual modeling: sketching timelines, charts and grids to model complex process measurement - simply ✲ Agile design documentation: enhancing star schemas with BEAM✲ dimensional shorthand notation ✲ Solving difficult DW/BI performance and usability problems with proven dimensional design patterns Lawrence Corr is a data warehouse designer and educator.
