The Problem with Survey Research
Author: George BeamPublisher: Routledge
ISBN: 1351476254
Category : Social Science
Languages : en
Pages : 243
Book Description
The Problem with Survey Research makes a case against survey research as a primary source of reliable information. George Beam argues that all survey research instruments, all types of asking-including polls, face-to-face interviews, and focus groups-produce unreliable and potentially inaccurate results. Because those who rely on survey research only see answers to questions, it is impossible for them, or anyone else, to evaluate the results. They cannot know if the answers correspond to respondents' actual behaviors (objective phenomena) or to their true beliefs and opinions (subjective phenomena). Reliable information can only be acquired by observation, experimentation, multiple sources of data, formal model building and testing, document analysis, and comparison. In fifteen chapters divided into six parts-Ubiquity of Survey Research, The Problem, Asking Instruments, Asking Settings, Askers, and Proper Methods and Research Designs-The Problem with Survey Research demonstrates how asking instruments, settings in which asking and answering take place, and survey researchers themselves skew results and thereby make answers unreliable. The last two chapters and appendices examine observation, other methods of data collection and research designs that may produce accurate or correct information, and shows how reliance on survey research can be overcome, and must be.
Power Piping
Author: Charles Becht (IV.)Publisher: American Society of Mechanical Engineers
ISBN: 9780791860144
Category : Technology & Engineering
Languages : en
Pages : 0
Book Description
This essential new volume provides background information, historical perspective, and expert commentary on the ASME B31.1 Code requirements for power piping design and construction. It provides the most complete coverage of the Code that is available today and is packed with additional information useful to those responsible for the design and mechanical integrity of power piping. The author, Dr. Becht, is a long-serving member of ASME piping code committees and is the author of the highly successful book, Process Piping: The Complete Guide to ASME B31.3, also published by ASME Press and now in its third edition. Dr. Becht explains the principal intentions of the Code, covering the content of each of the Code's chapters. Book inserts cover special topics such as spring design, design for vibration, welding processes and bonding processes. Appendices in the book include useful information for pressure design and flexibility analysis as well as guidelines for computer flexibility analysis and design of piping systems with expansion joints. From the new designer wanting to know how to size a pipe wall thickness or design a spring to the expert piping engineer wanting to understand some nuance or intent of the Code, everyone whose career involves process piping will find this to be a valuable reference.
Design & Applied Arts Index
Author: Fundamentals of Electric Propulsion
Author: Dan M. GoebelPublisher: John Wiley & Sons
ISBN: 0470436263
Category : Technology & Engineering
Languages : en
Pages : 528
Book Description
Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
Flipped
Author: Wendelin Van DraanenPublisher: Ember
ISBN: 0375825444
Category : Young Adult Fiction
Languages : en
Pages : 259
Book Description
A classic he-said-she-said romantic comedy! This updated anniversary edition offers story-behind-the-story revelations from author Wendelin Van Draanen. The first time she saw him, she flipped. The first time he saw her, he ran. That was the second grade, but not much has changed by the seventh. Juli says: “My Bryce. Still walking around with my first kiss.” He says: “It’s been six years of strategic avoidance and social discomfort.” But in the eighth grade everything gets turned upside down: just as Bryce is thinking that there’s maybe more to Juli than meets the eye, she’s thinking that he’s not quite all he seemed. This is a classic romantic comedy of errors told in alternating chapters by two fresh, funny voices. The updated anniversary edition contains 32 pages of extra backmatter: essays from Wendelin Van Draanen on her sources of inspiration, on the making of the movie of Flipped, on why she’ll never write a sequel, and a selection of the amazing fan mail she’s received. Awards and accolades for Flipped: SLJ Top 100 Children’s Novels of all time IRA-CBC Children’s Choice IRA Teacher’s Choice Honor winner, Judy Lopez Memorial Award/WNBA Winner of the California Young Reader Medal “We flipped over this fantastic book, its gutsy girl Juli and its wise, wonderful ending.” — The Chicago Tribune “Van Draanen has another winner in this eighth-grade ‘he-said, she-said’ romance. A fast, funny, egg-cellent winner.” — SLJ, Starred review “With a charismatic leading lady kids will flip over, a compelling dynamic between the two narrators and a resonant ending, this novel is a great deal larger than the sum of its parts.” —Publishers Weekly, Starred review
