Sustainability: A Comprehensive Foundation
Tom Theis; Jonathan Tomkin · OpenStax CNX · 2015
With “Sustainability: A Comprehensive Foundation”, first and second-year college students are introduced to this expanding new field, comprehensively exploring the essential concepts from every branch of knowledge – including engineering and the applied arts, natural and social sciences, and the humanities. As sustainability is a multi-disciplinary area of study, the text is the product of multiple authors drawn from the diverse faculty of the University of Illinois: each chapter is written by a recognized expert in the field. This text is designed to introduce the reader to the essential concepts of sustainability. This subject is of vital importance seeking as it does to uncover the principles of the long-term welfare of all the peoples of the planet but is only peripherally served by existing college textbooks. The content is intended to be useful for both a broad-based introductory class on sustainability and as a useful supplement to specialist courses which wish to review the sustainability dimensions of their areas of study. By covering a wide range of topics with a uniformity of style, and by including glossaries, review questions, case studies, and links to further resources, the text has sufficient range to perform as the core resource for a semester course. Students who cover the material in the book will be conversant in the language and concepts of sustainability, and will be equipped for further study in sustainable planning, policy, economics, climate, ecology, infrastructure, and more. Furthermore, the modular design allows individual chapters and sections to be easily appropriated without the purchase of a whole new text. This allows educators to easily bring sustainability concepts, references, and case studies into their area of study. This appropriation works particularly well as the text is free downloadable to anyone who wishes to use it. Furthermore, readers are encouraged to work with the text. Provided there is attribution to the source, use

Introduction to Probability
Charles Grinstead; J. Laurie Snell · American Mathematical Society · 2006
Probability theory began in seventeenth century France when the two great French mathematicians, Blaise Pascal and Pierre de Fermat, corresponded over two problems from games of chance. Problems like those Pascal and Fermat solved continuedto influence such early researchers as Huygens, Bernoulli, and DeMoivre in establishing a mathematical theory of probability. Today, probability theory is a wellestablished branch of mathematics that finds applications in every area of scholarlyactivity from music to physics, and in daily experience from weather prediction topredicting the risks of new medical treatments. This text is designed for an introductory probability course taken by sophomores,juniors, and seniors in mathematics, the physical and social sciences, engineering,and computer science. It presents a thorough treatment of probability ideas andtechniques necessary for a form understanding of the subject. The text can be usedin a variety of course lengths, levels, and areas of emphasis. For use in a standard one-term course, in which both discrete and continuousprobability is covered, students should have taken as a prerequisite two terms ofcalculus, including an introduction to multiple integrals. In order to cover Chapter 11, which contains material on Markov chains, some knowledge of matrix theoryis necessary. The text can also be used in a discrete probability course. The material has beenorganized in such a way that the discrete and continuous probability discussions arepresented in a separate, but parallel, manner. This organization dispels an overlyrigorous or formal view of probability and o?ers some strong pedagogical valuein that the discrete discussions can sometimes serve to motivate the more abstractcontinuous probability discussions. For use in a discrete probability course, studentsshould have taken one term of calculus as a prerequisite. Very little computing background is assumed or necessary in order to obtain fullbenefits from the use of the comp

Teaching in the University: Learning from Graduate Students and Early Career Faculty
Donna Westfall-Rudd; Courtney Vengrin; Jeremy Elliott-Engel · Virginia Tech Publishing · 2022
The primary objective of this book is to provide a resource for graduate teaching assistants who are looking for practical strategies and guidance as they begin their careers as postsecondary STEM educators. The text is designed to address a comprehensive list of topics to support the professional development of new faculty, recognizing that those holding academic faculty positions within a college or university are expected to be active in teaching, discovery, and outreach. Traditional doctoral education programs have historically emphasized preparation for research and scholarly publications, and for outreach. However, to some extent, many candidates who complete doctoral programs have minimal preparation and training in formal teaching. Contributors to this text have had a unique experience as part of a three-year, college-wide program designed to prepare interested doctoral students for a rewarding academic career. The program is designed to support the professional development of new faculty, recognizing that those holding academic faculty positions within a college or university are expected to be active in teaching, discovery, and outreach. The alumni and scholars of the program have worked collectively to gather resources and implement educational practices in the diverse set of courses they taught in during their three years in the program. Now as new faculty at a variety of postsecondary institutions across the United States, these early-career educators bring their insights and real-world teaching experiences, embedded in contemporary teaching and learning theory to their contributions to this text. What is this resource? This text is a collection of chapters and vignettes intended to provide practical insight into the challenges and opportunities of teaching at the postsecondary level. It is anticipated that the vignettes provide examples of contexts in which the principles of the topic chapters are applied. Goals for this book Support future STEM facult

Teaching Early and Elementary STEM
Alissa Lange; Laura Robertson; Jamie Price; Amie Craven · East Tennessee State University · 2021
This Open Access Educational textbook, "Teaching Early and Elementary STEM", was written to support pre-service early childhood and elementary teachers in their journey to become facilitators of science, technology, engineering, and math, or “STEM,” and "integrated STEM" in their future classrooms. Students who read and use this text will deepen their understanding of “STEM” and “integrated STEM,” learn what early childhood and elementary students need to know and be able to do in relation to STEM, and understand ways to create activity plans and implement current research-based approaches to teaching and pedagogy. This text arose out of our Early/Elementary STEM Collaboration project, which started in 2017 with the intention of increasing the quality of teacher preparation in STEM across early childhood and elementary education. The team is composed of math and science education professors, classroom in-service teachers, and pre-service teachers in pre-school through fifth grade. We are driven by the values of collaboration, strengths-based approaches to teaching and learning, constructivist philosophy of teaching and learning, and applied STEM experiences to increase access and equity. Our model of preparing pre-service teachers has been published elsewhere in more detail (Robertson, Nivens, & Lange, 2019). We built this open access product to include the following: 1) completely new content that includes input from our team as well as examples of integrated STEM learning experiences; 2) adaptations of existing resources, and; 3) compilations of existing free resources (e.g., Next Generation Science Standards).

Yet Another Introductory Number Theory Textbook (Cryptology Emphasis Version)
Jonathan Poritz · Jonathan Poritz · 2014
This version of YAINTT has a particular emphasis on connections to cryptology. The cryptologic material appears in Chapter 4 and §§5.5 and 5.6, arising naturally (I hope) out of the ambient number theory. The main cryptologic applications – being the RSA cryptosystem, Diffie-Hellman key exchange, and the ElGamal cryptosystem – come out so naturally from considerations of Euler’s Theorem, primitive roots, and indices that it renders quite ironic G.H. Hardy’s assertion [Har05] of the purity and eternal inapplicability of number theory. Note, however, that once we broach the subject of these cryptologic algorithms, we take the time to make careful definitions for many cryptological concepts and to develop some related ideas of cryptology which have much more tenuous connections to the topic of number theory. This material therefore has something of a different flavor from the rest of the text – as is true of all scholarly work in cryptology (indeed, perhaps in all of computer science), which is clearly a discipline with a different culture from that of “pure”mathematics. Obviously, these sections could be skipped by an uninterested reader, or remixed away by an instructor for her own particular class approach.

Evidence-based Software Engineering
Derek Jones · Knowledge Software · 2020
This book discusses what is currently known about software engineering, based on an analysis of all the publicly available data. This aim is not as ambitious as it sounds, because there is not a great deal of data publicly available. The intent is to provide material that is useful to professional developers working in industry; until recently researchers in software engineering have been more interested in vanity work, promoted by ego and bluster. The material is organized in two parts, the first covering software engineering and the second the statistics likely to be needed for the analysis of software engineering data.

Introduction to Statistical Thinking
Benjamin Yakir · Benjamin Yakir · 2010
The target audience for this book is college students who are required to learn statistics, students with little background in mathematics and often no motivation to learn more. It is assumed that the students do have basic skills in using computers and have access to one. Moreover, it is assumed that the students are willing to actively follow the discussion in the text, to practice, and more importantly, to think. Teaching statistics is a challenge. Teaching it to students who are required to learn the subject as part of their curriculum, is an art mastered by few. In the past I have tried to master this art and failed. In desperation, I wrote this book. This book uses the basic structure of generic introduction to statistics course. However, in some ways I have chosen to diverge from the traditional approach. One divergence is the introduction of R as part of the learning process. Many have used statistical packages or spreadsheets as tools for teaching statistics. Others have used R in advanced courses. I am not aware of attempts to use R in introductory level courses. Indeed, mastering R requires much investment of time and energy that may be distracting and counterproductive for learning more fundamental issues. Yet, I believe that if one restricts the application of R to a limited number of commands, the benefits that R provides outweigh the difficulties that R engenders. Another departure from the standard approach is the treatment of probability as part of the course. In this book I do not attempt to teach probability as a subject matter, but only specific elements of it which I feel are essential for understanding statistics. Hence, Kolmogorov’s Axioms are out as well as attempts to prove basic theorems and a Balls and Urns type of discussion. On the other hand, emphasis is given to the notion of a random variable and, in that context, the sample space.

Equilibrium Displacement Models: Theory, Applications, & Policy Analysis
Gary Brester; Joseph Atwood; Michael Boland · University of Minnesota Libraries Publishing · 2023
Applied economists frequently use equilibrium displacement models (EDMs), also termed linear elasticity models, for policy analyses because they can be used to estimate changes in prices and quantities that result from exogenous economic or policy shocks. These models are also widely used to estimate changes in producer and consumer surplus caused by exogenous economic shocks and to quantify the short- and long-term impacts of a variety of economic and regulatory actions across multiple markets. For the first time, a textbook that contains all of the theory and applications of EDMs along with a set of spreadsheet files is available in one place.

Policy Analysis of Multi-Actor System
Ben Enserink; Pieter Bots; Els van Daalen · TU Delft Open · 2022
Policy of Multi-Actor Systems is an introduction into the art of craft of problem exploration and problem structuring. It positions policy analysis as a scientific discipline focused on systems analysis in a multi-actor context to support better informed decision-making. The approach presented in this book is considered to be the cornerstone of the curricula of the Faculty of Technology, Policy and Management of Delft University of Technology and underlies the research on (the governance of) socio-technical systems. Systems thinking applied in a multi-actor environment and its inherent multi-disciplinary character is what makes this work stand out from traditional hard- and soft systems approaches. The core of the book is dedicated to systems analysis, actor- or stakeholder-analysis and discusses methods for dealing with uncertainty. These analytical activities combined lead to a rich problem description and to plans for further research. Due to the stepwise approach this book serves as a basis for any problem analysis both for our bachelor and master students, our alumni worldwide and any interested practitioners.
