Foundations in Statistical Reasoning
Peter Kaslik · Pierce College Fort Steilacoom
This book starts by presenting an overview of the statistical thought process. By the end of chapter 2, students are already familiar with concepts such as hypotheses, level of significance, p-values, errors. Normally these topics are not introduced until after a discussion of probability and sampling distributions. My approach to probability and sampling distributions is also very different.

Scholarly Communication Librarianship and Open Knowledge
Maria Bonn; Josh Bolick; Will Cross · Association of College and Research Libraries · 2023
The intersection of scholarly communication librarianship and open education offers a unique opportunity to expand knowledge of scholarly communication topics in both education and practice. Open resources can address the gap in teaching timely and critical scholarly communication topics—copyright in teaching and research environments, academic publishing, emerging modes of scholarship, impact measurement—while increasing access to resources and equitable participation in education and scholarly communication. Scholarly Communication Librarianship and Open Knowledge is an open textbook and practitioner’s guide that collects theory, practice, and case studies from nearly 80 experts in scholarly communication and open education. Divided into three parts: What is Scholarly Communication? Scholarly Communication and Open Culture Voices from the Field: Perspectives, Intersections, and Case Studies The book delves into the economic, social, policy, and legal aspects of scholarly communication as well as open access, open data, open education, and open science and infrastructure. Practitioners provide insight into the relationship between university presses and academic libraries, defining collection development as operational scholarly communication, and promotion and tenure and the challenge for open access.

Fundamentals of Psychological Disorders
Alexis Bridley; Lee Daffin Jr. · Washington State University · 2022
Fundamentals of Psychological Disorders (formerly Abnormal Psychology) is an Open Education Resource written by Alexis Bridley, Ph.D. and Lee W. Daffin Jr., Ph.D. through Washington State University. The book tackles the difficult topic of mental disorders in 15 modules and is updated through the DSM-5-TR. This journey starts by discussing what abnormal behavior is by attempting to understand what normal behavior is. Models of abnormal psychology and clinical assessment, diagnosis, and treatment are then discussed. With these three modules completed, the authors next explore several classes of mental disorders in 5 blocks. Block 1 covers mood, trauma and stressor related, and dissociative disorders. Block 2 covers anxiety, somatic symptom, and obsessive-compulsive disorders. Block 3 covers eating and substance-related and addictive disorders. Block 4 tackles schizophrenia spectrum and personality disorders. Finally, Block 5 investigates neurocognitive disorders and then ends with a discussion of contemporary issues in psychopathology. Disorders are covered by discussing their clinical presentation and DSM Criteria, epidemiology, comorbidity, etiology, and treatment options.

Geological Structures: a Practical Introduction
John Waldron; Morgan Snyder · Open Education Alberta · 2020
This manual is about structures that occur within the Earth’s crust. Structures are the features that allow geologists to figure out how parts of the Earth have changed position, orientation, size and shape over time. This work requires careful observation and measurements of features at the surface of the Earth, and deductions about what’s below the surface. The practical skills you will learn in this course form the foundation for much of what is known about the history of the Earth, and are important tools for exploring the subsurface. They are essential for Earth scientists of all kinds. The course that this document supports is about doing structural geology. It’s not possible to be a good geologist (or to pass the course) just by learning facts. You have to be able to solve problems. Do your lab work conscientiously and get as much as possible done during lab sessions when instructors are available to help you. This manual consists of both readings and lab exercises, which alternate through the text. The readings are designed to be read and understood outside the lab sessions, whereas the labs contain specific instructions and questions to be completed. Before each lab, be sure you have covered the readings that come immediately before it.

The Delft Sand, Clay & Rock Cutting Model
Sape Miedema · TU Delft Open · 2019
In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.

Comparative Vertebrate and Human Anatomy: Ecology, Evolution, and Function
Vanessa Hilliard; Lisa Whitenack; Bill Ryerson; Amy Cheu · PALNI · 2025
This book provides an ecology- and function-oriented approach to understanding the evolution of vertebrate structure. The text has a modular format, such that each module can be used as a stand-alone instructional tool, or grouped together as a comprehensive textbook, making the text versatile for use in courses with diverse structures. The text also includes human-specific modules for each anatomical system, as many small, liberal arts colleges teach comparative and human anatomy in a single course. Detailed, human-specific modules may be added or removed, as needed for individual courses, depending on the scope and learning objectives of the class.
