Carefully coordinated, reliable, and accurate time synchronization is vital to a wide spectrum of fields-from air and ground traffic control, to buying and selling goods and services, to TV network programming. Ill-gotten time could even lead to the unimaginable and cause DNS caches to expire, leaving the entire Internet to implode on the root servers. Written by the original developer of the Network Time Protocol (NTP), Computer Network Time Synchronization: The Network Time Protocol on Earth and in Space, Second Edition addresses the technological infrastructure of time dissemination, distribution, and synchronization-specifically the architecture, protocols, and algorithms of the NTP. This system has been active in one form or another for almost three decades on the Internet and numerous private networks on the nether side of firewalls. Just about everything today that can be connected to a network wire has support for NTP. This book: Describes the principal components of an NTP client and how it works with redundant servers and diverse network paths Provides an in-depth description of cryptographic and other critical algorithms Presents an overview of the engineering principles guiding network configuration Evaluating historic events that have taken place since computer network timekeeping started almost three decades ago, the author details a number of systems and drivers for current radio, satellites, and telephone modem dissemination and explains how we reckon the time, according to the stars and atoms. The original 16 chapters of the first edition have been rewritten, updated, and enhanced with new material. Four new chapters cover new algorithms and previously uncovered concepts, including timekeeping in space missions. Praise for the first edition: "... For those that need an exhaustive tome on all of the minutiae related to NTP and synchronization, this is the source. ... definitive ... this book should be considered the last word on the topic." -Ben Rothke on Slashdot.org "... the bible of the subject... contains enough information to take you just as far as you want to go....Dr. Mills is the original developer of NTP." -Books On-Line

Population ecology has matured to a sophisticated science with astonishing potential for contributing solutions to wildlife conservation and management challenges. And yet, much of the applied power of wildlife population ecology remains untapped because its broad sweep across disparate subfields has been isolated in specialized texts. In this book, L. Scott Mills covers the full spectrum of applied wildlife population ecology, including genomic tools for non-invasive genetic sampling, predation, population projections, climate change and invasive species, harvest modeling, viability analysis, focal species concepts, and analyses of connectivity in fragmented landscapes. With a readable style, analytical rigor, and hundreds of examples drawn from around the world, "Conservation of Wildlife Populations (2nd ed)" provides the conceptual basis for applying population ecology to wildlife conservation decision-making. Although targeting primarily undergraduates and beginning graduate students with some basic training in basic ecology and statistics (in majors that could include wildlife biology, conservation biology, ecology, environmental studies, and biology), the book will also be useful for practitioners in the field who want to find - in one place and with plenty of applied examples - the latest advances in the genetic and demographic aspects of population ecology.Additional resources for this book can be found at: www.wiley.com/go/mills/wildlifepopulations.

The Secondary Lenses on Learning professional development materials were designed to support the efforts of site-based mathematics improvement teams of mathematics leaders to advance middle and high school students' mathematics achievement. Participants in the Secondary Lenses on Learning program will expand their understanding of the mathematical knowledge and dispositions that students need to be mathematically literate in today's world and the learning opportunities that need to be created to make significant mathematics accessible to all students. The Secondary Lenses on Learning Participant Book features detailed notes for each of the six sessions, corresponding readings, handouts, and assignments. Over the course of the Secondary Lenses on Learning sessions, participants will: - Explore concepts in middle and high school algebra - Discuss readings that illuminate the issues in each session - Reflect on filmed material and written cases - Examine various leadership tasks and responsibilities that contribute to an effective mathematics program Multiple copies of the participant books are available separately to accommodate your group's specific needs. For the facilitator, the Secondary Lenses on Learning comprehensive package includes one participant book, one facilitator's guide, and an accompanying DVD with segments that correlate to individual sessions.

Introduction to Ethnographic Research streamlines learning the process of research, speaks to the student at a foundational level, and helps the reader conquer the apprehensions of mastering research methods. Written in a conversational style, authors Kimberly Kirner and Jan Mills use a focus on scaffolding across the chapters to help the student transition from step to step in the research process. Case studies and first-hand accounts are also featured in each chapter, allowing the student to see the early steps, successes and at times failures that accomplished researchers experienced in their past. These real examples further encourage the student that even the best researchers failed along the way, and more importantly, learned from those mistakes. This text is designed to be used as a stand alone book, but is enhanced by the use with the supplemental workbook, Doing Ethnographic Research by the same authors. This text has call-outs to the supplemental text, which allow for application and practice of the material learned.

This workbook is loaded with exercises, how-to sections and checklists, all designed to serve as a supplemental support for students to apply the principles and concepts learned from the textbook it accompanies. With instructions and explanations written in a conversational style, it will help the student understand why the assignments are being used, why the skills they are developing are relevant and how the exercises relate to the textbook content.

This Lenten devotional invites readers to learn more about the brutal institution of slavery and its impact on Black people in America and recognize how its evolution and legacy continue to harm their descendants in the United States today. Each of the forty devotions includes the testimony of a person who escaped slavery through the Underground Railroad, a Scripture passage, and a reflection connecting biblical and historical themes to challenge modern readers to work for liberation. Reflecting on Lenten themes of exodus, redemption, discipline, and repentance, readers, both Black and white, will be empowered for the work of racial justice.

This is a new release of the original 1936 edition.

This story is about the fun memories and love I have for my Mom. It's the pain of knowing that my Mother has Dementia. Sometimes life can bring us so much Joy and Pain. It's how you embrace the pain to get you to the joy in our life. I pray that this book touches the hearts of those who are going through some of the same experiences that I'm going through.

This book is the fifth in a series devoted to the theory and practice of inelastic light scattering (Raman and Brillouin) as applied to amorphous and crystalline solids. This volume is concerned with the investigation by these techniques of artificial periodic structures prepared by such gas-phase deposition techniques as Molecular Beam Epitaxy. The phenomena treated involve phonons, magnons, plasmons, and other electronic excitations. The book supplies theoretical background, information on modern experimental techniques such as multichannel detectors, and a number of experimental results.
