Call and response has an important history in traditional West African music, especially in spiritual music and protest movements. Although the specific expression of this practice varies across the diaspora depending on the geographic location and musical lineage of practitioners, there are striking similarities in seemingly disparate locations, like the southern United States, Cuba, and northern Brazil. The preservation of call and response practices within these locations (and many others) suggests the importance of collectivity when healing from systemic oppression.

With this interest in mind, David Diaz invites students to join into this call and response by listening to and producing sounds and/or movements as they are comfortable. In joining a collective, there is also space for individuality, and even dissonance. In that interest, students can recognize the shared histories and practices that the music reveals, as well as the particularities of specific cultures and historical actors.

In this course, we will seek to interpret capitalism using ideas from biological evolution: firms pursuing varied strategies and facing extinction when those strategies fail are analogous to organisms struggling for survival in nature. For this reason, it is less concerned with ultimate judgment of capitalism than with the ways it can be shaped to fit our more specific objectives Š—– for the natural environment, public health, alleviation of poverty, and development of human potential in every child. Each book we read will be explicitly or implicitly an argument about good and bad consequences of capitalism.

This patient education program explains cataracts including the symptoms, diagnosis, complications, and treatment options. It also discusses the risks and benefits of surgery and what to expect after the procedure. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

Like most introductory science textbooks, this one opens with a discussion of scientific method. A key feature is its focus on experimental support for what we know about cell and molecular biology. Understanding how science is practiced and how investigators think about experimental results is essential to understanding the relationship of cell structure and function…, not to mention our relationship to the natural world. This is a free Open Education Resource (OER), covered by a Creative Commons CCBY license (check out the Preface!). Every chapter begins with learning objectives and links to relevant recorded lectures. As used by the author, the iText engages students with embedded “just-in-time” learning tools. These include instructor’s annotations (comments) directing students to animations or text of interest, as well as links to writing assignments and quizzes. These interactive features aim to strengthen critical thinking and writing skills necessary to understand cell and molecular biology, not to mention science as a way of thinking in general. Please excuse the marketing terms, but you can choose between Bronze, Silver, or Gold versions, reflecting increasing potential for student interaction with the iText.

This series focuses on the work of The Centre for the Study of African Economies (CSAE) - an economic research centre within the Department of Economics at Oxford University. These short talks look at specific research topics within the CSAE and are aimed at people who are interested in learning more about African and other world Economies such as Latin America. CSAE researchers often use unique data which give them unrivaled insight into the underlying issues. The resulting policy recommendations address questions in the economic and political spheres as well as in civil society in developing countries.

This patient education program explains cerebral palsy (CP), the causes and risk factors, symptoms and complications, diagnosis, prevention, and treatment options. It also reviews brain anatomy, particularly that of the motor skills areas. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

The course facilitates a close reading of Don Quixote in the artistic and historical context of renaissance and baroque Spain. Students are also expected to read four of Cervantes' Exemplary Stories, Cervantes' Don Quixote: A Casebook, and J.H. Elliott's Imperial Spain. Cervantes' work will be discussed in relation to paintings by Vel’zquez. The question of why Don Quixote is read today will be addressed throughout the course. Students are expected to know the book, the background readings and the materials covered in the lectures and class discussions.

This patient education program reviews the anatomy of the gallbladder, symptoms of gallstones, treatment options, and the benefits and risks of cholecystectomy. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

This course explores the causes, course, and consequences of the American Civil War, from the 1840s to 1877. The primary goal of the course is to understand the multiple meanings of a transforming event in American history. Those meanings may be defined in many ways: national, sectional, racial, constitutional, individual, social, intellectual, or moral. Four broad themes are closely examined: the crisis of union and disunion in an expanding republic; slavery, race, and emancipation as national problem, personal experience, and social process; the experience of modern, total war for individuals and society; and the political and social challenges of Reconstruction.

This patient education program explains clinical trials and answers some frequently asked questions. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

This flash animation for the song "Closer to Free" describes the Economic Freedom of the World index, provides a summary of countries with high and low values of the index, and highlights the importance of economic freedom in a country's standard of living.

This site houses a large number of very brief audio files in which native speakers say brief, useful, every day phrases in a number of conjugations. Phrases include things like "How much is this?" "How are you?" or simply reciting useful vocabulary and also cover numbers and time. Each phrase is spoken in 8 or 9 dialects from the regions of North Africa, the Levant, and the Persian Gulf. Every phrase is accompanied by a transcript.

This unit provides a foundation on how a computer functions and how data is represented in memory, input and output devices, and the CPU, including its role in system functionality.

For all intents and purposes, this show is the fourth edition of the textbook Computer Organization and Design Fundamentals by David Tarnoff. Since the first edition came out in 2005, the PDFs have been made free for download to anyone interested in computer organization. With the trend toward audio and video instructional material, it was time for an update.

The presentation of the material in this series will be similar to that of the original textbook. In the first third, we will discuss the mathematical foundation and design tools that address the digital nature of computers. This will include an introduction to the differences between the physical world and the digital world, how those differences affect the way the computer represents and manipulates data, and the use and design of digital logic and logic gates. In the second third, the fundamentals of the digital logic and design will be used to design common circuits such as binary adders, describe checksums and cyclic redundancy checks, network addressing, storage devices, and state machines. The final third will examine the top-level view of the computer. This will include a discussion of the memory hierarchy and its components, the components of a CPU, and maybe even a discussion of assembly language along with some examples.

This unit discusses the purpose and types of programming languages from simple machine code to high level programming languages, including the process of compiling and interpreting. Students will use variables, loops and conditional statements to build a simple program. Finally, this unit presents some advanced programming concepts such as Object Oriented Programming.

This unit covers application and system software, with a focus on healthcare systems. It also describes the functions of operating systems, presents different operating systems, and defines the purpose and usage of file systems.
