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.

Essentials of Geographic Information Systems integrates key concepts behind the technology with practical concerns and real-world applications. Recognizing that many potential GIS users are nonspecialists or may only need a few maps, this book is designed to be accessible, pragmatic, and concise. Essentials of Geographic Information Systems also illustrates how GIS is used to ask questions, inform choices, and guide policy. From the melting of the polar ice caps to privacy issues associated with mapping, this book provides a gentle, yet substantive, introduction to the use and application of digital maps, mapping, and GIS.

Long Description:
Click on Volume 1 to read the first book in this series.
This book is the result of a co-design project in a class in the Masters of Education program at the University of Calgary. The course, and the resulting book, focus primarily on the safe and ethical use of technology in digital learning environments, and is the second volume in the series. The course was organized according to four topics based on Farrow’s (2016) Framework for the Ethics of Open Education. Students were asked to review, analyze, and synthesize each topic from three meta-ethical theoretical positions: deontological, consequentialist, and virtue ethical (Farrow, 2016). The chapters in this open educational resource (OER) were co-designed using a participatory pedagogy with the intention to share and mobilize knowledge with a broader audience. The first section, comprised of four chapters, focuses on topics relating to well-being in technology-enabled learning environments, including the use of web cameras, eproctoring software, video games, and access to broadband connectivity. The second section focuses on privacy and autonomy of learners and citizens in a variety of contexts from schools to clinical settings. In each of the seven chapters, the authors discuss the connection to the value of technology in education, and practical possibilities of learning technologies for inclusive, participatory, democratic, and pluralistic educational paradigms. The book concludes with reflections from the course instructor gained over two iterations of teaching the course.

This course considers the interaction between law, policy, and technology as they relate to the evolving controversies over control of the Internet. In addition, there will be an in-depth treatment of privacy and the notion of “transparency” – regulations and technologies that govern the use of information, as well as access to information. Topics explored will include:
Legal Background for Regulation of the Internet
Fourth Amendment Law and Electronic Surveillance
Profiling, Data Mining, and the U.S. PATRIOT Act
Technologies for Anonymity and Transparency
The Policy-Aware Web
This chapter’s objective is to raise interesting tax ethics issues in practical contexts. There are 42 notes and questions to prompt and guide discussions, and primary source materials to inform the discussions (e.g., cases, IRC provisions, and Circular 230 excerpts).

This course is a practicum-style seminar in anthropological methods of ethnographic fieldwork and writing. Depending on student experience in ethnographic reading and practice, the course is a mix of reading anthropological and science studies ethnographies; and formulating and pursuing ethnographic work in local labs, companies, or other sites.
Students explore the chemical identities of polymeric materials frequently used in their everyday lives. They learn how chemical composition affects the physical properties of the materials that they encounter and use frequently, as well as how cross-linking affects the properties of polymeric materials.
This module consists of a laboratory exercise and related homework problems on geochemical kinetics of mineral-solution reactions for undergraduate mineralogy. Students measure the grain sizes of equant halite crystals, and the time for complete dissolution of each grain. From these data, students retrieve a rate law, from several possible. Additional homework problems allow various chemical and physical transport processes in mineral-fluid systems to be evaluated.
The lab and homework illustrate several basic principles of chemical kinetics directly relevant to geology, including rate laws of reactions, diffusion, advective transport, and the relationship between rate-limiting mechanisms and crystal-surface morphology.

1. Instructor identifies an appropriate number of key dates in the Precambrian to investigate.
2. Students break into groups (method to be determined by instructor) and each group will be assigned a particular time in the Precambrian (one author likes to have groups draw assignments out of hat!).
3. Students investigate their time period using appropriate source materials (we suggest the class notes, textbook and perhaps supplementary materials identified in the form of popular articles (e.g., Scientific American, Smithsonian, National Geographic, etc.) or websites.

In this class, students engage in independent research projects to probe various aspects of the physiology of the bacterium Pseudomonas aeruginosa PA14, an opportunistic pathogen isolated from the lungs of cystic fibrosis patients. Students use molecular genetics to examine survival in stationary phase, antibiotic resistance, phase variation, toxin production, and secondary metabolite production.
Projects aim to discover the molecular basis for these processes using both classical and cutting-edge techniques. These include plasmid manipulation, genetic complementation, mutagenesis, PCR, DNA sequencing, enzyme assays, and gene expression studies. Instruction and practice in written and oral communication are also emphasized.

A focus on novel, confirmatory, and statistically significant results leads to substantial bias in the scientific literature. One type of bias, known as “p-hacking,” occurs when researchers collect or select data or statistical analyses until nonsignificant results become significant. Here, we use text-mining to demonstrate that p-hacking is widespread throughout science. We then illustrate how one can test for p-hacking when performing a meta-analysis and show that, while p-hacking is probably common, its effect seems to be weak relative to the real effect sizes being measured. This result suggests that p-hacking probably does not drastically alter scientific consensuses drawn from meta-analyses.
Trade benefits both buyers and sellers, but what happens when the transaction affects a third party? In this video, Professor Michael Munger of Duke University defines the term externality and explains different ways to solve the problem of externalities.
Species extinction is happening at an alarming rate according to scientists. In this lesson, students are asked to consider why extinction is a problem that we should concern us. They are taught that destruction of habitat is the main reason many species are threatened. The lesson explores ways that engineers can help save endangered species.
In order to get the most out of a piece of literature, students must empathize with the characters, try to understand what motivates the main characters, and how those characters perceive of and interact with their world. The way that our students perceive of and interact with their world is changing all the time. At this point in history, however, digital communication the key. Therefore, as teachers, if we can bring social media into the realm of literature, we have a better chance of engaging the students and getting them to see what lies within the protagonists on the page. This project has the student create a Facebook page for a character in the story, allowing each student to embody that character and interact with others from within that text or intertextually.
