Book Description
Conrad Hal Waddington's Organisers and Genes, published in 1940, is a summary of available research and theoretical framework for many concepts related to tissue differentiation in the developing embryo. The book is composed of two main conceptual sections. The first section explores the action and nature of the organizer, while the second section delves into genes and their influence on development. In this book Waddington explored organizers in terms of their capacity and method of induction. First he examined the nature of induction, discussing crucial experiments concerning the organizer, including Hans Spemann's discovery of the organizer, and his own research into organizers in higher birds and mammals. Waddington separated the action of the organizer into two distinct categories, evocation and individuation, discussed below. The main experimental approach discussed in this book involved grafting organizing tissue from one embryo or region of an embryo to another. Waddington described evocation as non-assimilative induction, or a one-way inducing signal. He presented this as a chemical signal and illustrated evocation with the dead organizer experiment. The dead organizer was shown to be capable of inducing differentiation of neural tissue in the ectoderm. He also included chemical induction by estrogens and steroids as other evocative signals. An important aspect of any signal of evocation, as presented by Waddington, is that the signal is specific to the differentiation of a certain tissue type.

Book Description
Why are some civic associations better than others at getting - and keeping - people involved in activism? From MoveOn.org to the National Rifle Association, Health Care for America Now to the Sierra Club, membership-based civic associations constantly seek to engage people in civic and political action. What makes some more effective than others? Using in-person observations, surveys, and field experiments, this book compares organizations with strong records of engaging people in health and environmental politics to those with weaker records. To build power, civic associations need quality and quantity (or depth and breadth) of activism. They need lots of people to take action and also a cadre of leaders to develop and execute that activity. Yet, models for how to develop activists and leaders are not necessarily transparent. This book provides these models to help associations build the power they want and support a healthy democracy. In particular, the book examines organizing, mobilizing, and lone wolf models of engagement and shows how highly active associations blend mobilizing and organizing to transform their members' motivations and capacities for involvement. This is not a simple story about the power of offline versus online organizing. Instead, it is a story about how associations can blend both online and offline strategies to build their activist base. In this compelling book, Hahrie Han explains how civic associations can invest in their members and build the capacity they need to inspire action.

Book Description
"The world is changing rapidly and the practice of community organizing needs to change with it. Representing both an homage to, and a departure from the "alinsky traditions" of organizing, Consensus Organizing offers techniques that are specifically designed for urban and rural communities struggling to succeed in the global economy and the information age. Ohmer and DeMasi are experienced organizers who offer a relentlessly thorough examination of the process of bringing diverse communities together to make change and to bridge the ethnic and economic divisions that keep many communities from succeeding." —Bill Traynor Executive Director, Lawrence CommunityWorks Inc. A person doesn′t have to be a consensus organizer to think like one. Consensus Organizing: A Community Development Workbook—A Comprehensive Guide to Designing, Implementing, and Evaluating Community Change Initiatives helps students and practitioners begin to think like consensus organizers and incorporate this way of strategic thinking into their lives and their work. Through a wide range of exercises, role-play activities, case scenarios, and discussion questions, this workbook presents the conceptual framework for consensus organizing and provides a practical and experiential approach to understanding and applying consensus organizing to address a range of issues. This workbook is designed to be used by itself or along with Mike Eichler′s text Consensus Organizing: Building Communities of Mutual Self Interest (SAGE, 2007). Key Features and Benefits Provides a step-by-step guide on how to conduct a community analysis of both internal and external neighborhood resources Brings consensus organizing to life through case studies based on the real-life experiences of the authors Offers field exercises that engage the reader in applying and practicing consensus organizing Provides practical tools that community organizers and practitioners can use in their daily work Includes a sample job description, work plan, monitoring report, and field report for hiring and supervising consensus organizers Presents tools for describing and evaluating consensus organizing and community-level interventions Accompanying Website Instructors and students have access to the many activities and cases on the accompanying website.

Book Description
Note about this ebook: This ebook exploits many advanced capabilities with images, hypertext, and interactivity and is optimized for EPUB3-compliant book readers, especially Apple's iBooks and browser plugins. These features may not work on all ebook readers. We organize things. We organize information, information about things, and information about information. Organizing is a fundamental issue in many professional fields, but these fields have only limited agreement in how they approach problems of organizing and in what they seek as their solutions. The Discipline of Organizing synthesizes insights from library science, information science, computer science, cognitive science, systems analysis, business, and other disciplines to create an Organizing System for understanding organizing. This framework is robust and forward-looking, enabling effective sharing of insights and design patterns between disciplines that weren’t possible before. The Professional Edition includes new and revised content about the active resources of the "Internet of Things," and how the field of Information Architecture can be viewed as a subset of the discipline of organizing. You’ll find: 600 tagged endnotes that connect to one or more of the contributing disciplines Nearly 60 new pictures and illustrations Links to cross-references and external citations Interactive study guides to test on key points The Professional Edition is ideal for practitioners and as a primary or supplemental text for graduate courses on information organization, content and knowledge management, and digital collections. FOR INSTRUCTORS: Supplemental materials (lecture notes, assignments, exams, etc.) are available at http://disciplineoforganizing.org. FOR STUDENTS: Make sure this is the edition you want to buy. There's a newer one and maybe your instructor has adopted that one instead.

Book Description
NEW YORK TIMES BESTSELLER • From the stars of the Netflix series Get Organized with The Home Edit (with a serious fan club that includes Reese Witherspoon, Gwyneth Paltrow, and Mindy Kaling), here is an accessible, room-by-room guide to establishing new order in your home. “A master class on how to arrange even your most unattractive belongings—and spaces—in an aesthetically pleasing and easy-to-navigate way.”—Glamour (10 Books to Help You Live Your Best Life) Believe this: every single space in your house has the potential to function efficiently and look great. The mishmash of summer and winter clothes in the closet? Yep. Even the dreaded junk drawer? Consider it done. And the best news: it’s not hard to do—in fact, it’s a lot of fun. From the home organizers who made their orderly eye candy the method that everyone swears by comes Joanna and Clea’s signature approach to decluttering. The Home Edit walks you through paring down your belongings in every room, arranging them in a stunning and easy-to-find way (hello, labels!), and maintaining the system so you don’t need another do-over in six months. When you’re done, you’ll not only know exactly where to find things, but you’ll also love the way it looks. A masterclass and look book in one, The Home Edit is filled with bright photographs and detailed tips, from placing plastic dishware in a drawer where little hands can reach to categorizing pantry items by color (there’s nothing like a little ROYGBIV to soothe the soul). Above all, it’s like having your best friends at your side to help you turn the chaos into calm. Includes a link to download and print the labels from a computer (you will need 8-1/2 x 11-inch clear repositionable sticker project paper, such as Avery 4397).
