This book will give you a practical overview of several methods and approaches for designing mobile technologies and conducting mobile user research, including how to understand behavior and evaluate how such technologies are being (or may be) used out in the world. Each chapter includes case studies from our own work and highlights advantages, limitations, and very practical steps that should be taken to increase the validity of the studies you conduct and the data you collect. This book is intended as a practical guide for conducting mobile research focused on the user and their experience. We hope that the depth and breadth of case studies presented, as well as specific best practices, will help you to design the best technologies possible and choose appropriate methods to gather ethical, reliable, and generalizable data to explore the use of mobile technologies out in the world.
This is a charming series of essays on animal behavior, written in 1951 by the note British science writer Frank W. Lane, reveals obscure and fascinating oddities of animal behavior. The clear, logical explanation behind each bizarre happening grounds the observations in scientific research, and provides modern readers insight on mid-century scientific field methodology. Here are some of the cases featured in this fantastic compilation: Do bees tell time and tell each other of honey locations? Can game animals dodge bullets? Have fish an ear for music? Do birds hitch hike on each other’s backs? These questions and thousands of others are answered with scientific proof. Natural history fans, history of science buffs, and explorers of nature will find hours of fascinating reading within. A true mine of conversational material and arbiter of game controversies!
The skeleton is a multifunctional organ system that serves several vital roles in the body. Although bone has the ability to remodel itself to repair damage and respond to calcium demands, it is subject to the rigors of aging, hormonal changes, and environment. Understanding the mechanisms that cause bone loss is an important facet of human medicine. Animal models permit mechanistic study of processes that regulate development and maintenance of skeletal mass, enabling meticulous investigation of new orthopedic strategies or bone-targeted pharmacologic therapies. The selection of an appropriate animal model, choice of skeletal analysis techniques, and proper interpretation of data are vital components of experimental design and analysis in bone research. In this chapter, we review time-tested criteria for choosing appropriate animal models, describe several common animal models of osteoporosis, and summarize some of the basic methodology available for in vivo, ex vivo and in vitro analysis of skeletal biology.
