Defend Dissent is an introduction to cryptography paired with the social impacts of surveillance and the protective potential of encryption, with a focus on US social movements. Each chapter ends with a story that brings social context to the material—from surveillance used against contemporary US protests to the African National Congress’s use of partially manual encryption in fighting apartheid in South Africa in the 80s.

This book can be read linearly, or you can pick and choose what you would like to learn about. Each chapter is prefaced with what you should read first (for background) and concludes with what you might want to read next.

Every farm, ranch, nursery, dairy, or other agricultural operation is more than a business. It is a connection to family and tradition and provides essential food, fiber, fuel, and other benefits for society. But without attention to the farm as a business, it will not survive into the future or continue to provide those important connections and services. A farm’s management succession and estate planning are often uncomfortable topics for everyone involved. However, they are essential to protect and extend the agricultural operation.

Based on over 20 years of teaching experience in animal nutrition, this study guide will enhance learning basic food animal nutritional principles.

In this introductory text, six fundamental nutrients, their structure, digestion, and metabolism are covered. A brief introduction to bioenergetics, feed additives, nutrient analysis, digestive organs and processes in monogastric and ruminant animals, and methods for assessing nutrient utilization are also included.

Each chapter is illustrated with a new terms box, key points, and review questions.

This study guide is an essential learning tool for undergraduate students majoring in animal sciences, veterinary medicine, or other related disciplines.

The flexbook is divided into 13 chapters with sections and subsections. These are numbered in such a way that the first number represents the chapter. A period separates the chapter from the section number, and another period is followed by the subsection number. The figures are non-copyrighted figures or I have made them myself in PowerPoint. The flexbook also contains links to articles, videos, and animations in Web Link boxes. These can be clicked to open the link, and urls for these resources are also provided at the end of the section or subsection.

Learners will be able to 1) describe different integrated pest management techniques for controlling agricultural pests and 2) identify environmental/economical advantages and disadvantages of different pest management methods

This open text in progress is designed for use in CS 210 at University of Oregon and in CS 161 at other Oregon colleges and universities.

Permaculture Design is a method of land planning that can be applied at scales from the home garden to city block to village to farm. It is an ethically based whole-systems design approach that uses concepts, principles, and methods derived from ecosystems, indigenous technologies, and other time-tested practices to create sustainable human settlements and institutions. Although rooted in horticulture and agriculture, Permaculture design is interdisciplinary, touching on a wide range of subjects including regional planning, ecology, animal husbandry, appropriate technology, architecture, social justice, and international development.

This open text book is derived from the content of the Massive Open Online Course “Intro to Permaculture”. The original course also included interactive mapping and design tools that accompanied this content. The course and book provide a general overview of the Permaculture design system. The book can be downloaded as a print version. However, there are many accompanying videos and content pages that are linked to throughout the text, so it is best viewed online where the links can be accessed.

These are lecture notes for cs427 at Oregon State University, an introductory course in cryptography at the advanced undergraduate level. By reading and studying these notes, you should expect to learn how to:

*State and interpret the standard formal definitions for the most common cryptographic security properties (privacy and authentication).
*Formally prove security properties of sound cryptographic constructions, and break the security of unsound ones.
*Choose the appropriate cryptographic primitive for a task (block ciphers, hash functions, MACs, public-key encryption, etc.) while avoiding common pitfalls.
*Along the way, you will also learn how the most common cryptographic constructions work.

This open educational resource is designed for use by undergraduate and graduate ocean science, natural resource, fisheries and wildlife, and environmental policy students enrolled in a ten-week academic quarter. The purpose of this project is to provide students and non-law professionals with a freely accessible, clearly written guide to support engaging and effective learning. As such, the book serves as a gateway and an invitation to become a well informed, committed and involved ocean citizen as well as to explore the field beyond our course study.

Climate is also where we begin the design process in another tool referenced in the Permaculture design system. This is the Scale of Landscape Permanence, originated by P.A.Yeomans, the founder of Keyline™ Design. Yeomans asserts that the order of design is:

Climate
Landshape
Water Supply
Roads/Access
Trees
Structures
Subdivision Fences
Soil
This book is predominantly about climate, and the macro influences of climate and climate change on design. As we get through the topics of climate analogues and climate change forecasting, we will end up moving down this list to see the climate’s influence on specific design choices.

A Primer for Computational Biology aims to provide life scientists and students the skills necessary for research in a data-rich world. The text covers accessing and using remote servers via the command-line, writing programs and pipelines for data analysis, and provides useful vocabulary for interdisciplinary work. The book is broken into three parts:

Introduction to Unix/Linux: The command-line is the “natural environment” of scientific computing, and this part covers a wide range of topics, including logging in, working with files and directories, installing programs and writing scripts, and the powerful “pipe” operator for file and data manipulation.
Programming in Python: Python is both a premier language for learning and a common choice in scientific software development. This part covers the basic concepts in programming (data types, if-statements and loops, functions) via examples of DNA-sequence analysis. This part also covers more complex subjects in software development such as objects and classes, modules, and APIs.
Programming in R: The R language specializes in statistical data analysis, and is also quite useful for visualizing large datasets. This third part covers the basics of R as a programming language (data types, if-statements, functions, loops and when to use them) as well as techniques for large-scale, multi-test analyses. Other topics include S3 classes and data visualization with ggplot2.

Students will be able to describe the types of soil erosion and explain the methods for prevention

Students will learn how to collect quality soil samples and how soil testing is done

The forest industry is increasingly global and every marketer of forest products should have a global perspective. As a natural resource-based industry, the forest industry has an especially high profile role in environmental protection and is increasingly involved in climate change mitigation and management. Global forests are not only important because they provide a source of industrial raw material, but also because of the various other human needs they satisfy. A forest products marketer should have a basic understanding of the role that global forests play in society. Major societal trends are impacting the external environment within which the forest industry operates. We provide an overview of global forests and a brief description of the markets for the main categories of the forest industry.

This is the story of a web-based information system rebuild. The system in question is www.teachengineering.org, a digital library of K-12 engineering curriculum that was built from the ground up with established technology and which for 13 years enjoyed lasting support from its growing user community and its sponsors. These 13 years, however, cover the period during which smart phones and tablets became commonplace, during which the Internet of Things started replacing the Semantic Web, during which NoSQL databases made their way out of the research labs and into everyday development shops, during which we collectively started moving IT functions and services into ‘the cloud,’ and during which computing performance doubled a few times, yet again. During this same period, TeachEngineering’s user base grew from a few hundred to more than 3 million users annually, its collection size quadrupled, it went through several user interface renewals, and significant functionality was added while having an exemplary service record, and it enjoyed continued financial support from its sponsors.

In this monograph we provide a side-by-side of this rebuild. We lay out the choices made in the old architecture —we refer to it as TE 1.0— and compare and contrast them with the choices made for TE 2.0. We explain why both the 1.0 and 2.0 choices were made and discuss the advantages and disadvantages associated with them.

The MATLAB programming language is commonly used in engineering and scientific computation. I wrote this book to give first year students a basic introduction to MATLAB syntax and algorithmic thinking. This is by no means a comprehensive resource. It is meant to get students started and allow them to transition to more complex material.

The book is structured as a tutorial rather than a reference. The MATLAB documentation is extensive and so my focus will be to outline basic algorithmic thinking and MATLAB syntax with explicit examples. I encourage students to work through the chapters in order as each new concept builds on previous material.

The initial chapters require only basic algebra and geometry, so they are accessible to students at any point in their math sequence. Many of the problems in these chapters will seem simple or tedious. They are. The purpose is to separate the skill that you wish to develop (MATLAB programming) from other skills which need to be developed. The simple problems allow you to focus on the hard work of communicating with the computer. Once you’re comfortable with that, then you try to apply algorithmic thinking to more interesting problems.

A la defensa del disenso es una introducción a la criptografía que atiende los efectos sociales de la vigilancia, así como el potencial de protección que brinda el cifrado, con un enfoque en los movimientos sociales nacidos en Estados Unidos. Cada capítulo termina con una historia que aporta un contexto social al material: desde la vigilancia contra protestas contemporáneas en Estados Unidos, hasta la forma en que el Congreso Nacional Africano usó cifrado parcialmente manual para luchar contra el Apartheid en la Sudáfrica de los años 80 del siglo pasado.
