This presentation introduces Computer Science students to the notion of accessibility: developing software for people with disabilities. This lesson provides a discussion of why accessibility is important (including the legal, societal and ethical benefits) as well as an overview of different types of impairments (visual, auditory, motor, neurological/cognitive) and how developers can make their software accessible to users with those disabilities. This lesson includes videos and links to readings and tutorials for students.

The purpose of this course is to examine the African American experience in the United States from 1863 to the present. Prominent themes include the end of the Civil War and the beginning of Reconstruction; African Americans' urbanization experiences; the development of the modern civil rights movement and its aftermath; and the thought and leadership of Booker T. Washington, Ida B. Wells-Barnett, W.E.B. Du Bois, Marcus Garvey, Martin Luther King Jr., and Malcolm X. WARNING: Some of the lectures in this course contain graphic content and/or adult language that some users may find disturbing.

Jason Allen offers a comparative discussion of two important Caribbean poets and playwrights, Aime Cesaire and Derek Walcott, to emphasize the impact of Caribbean literature upon the postcolonial world. By using biographical and historical detail to support his analysis of some of Cesaire and Walcott's key texts, Allen offers insight into what it means to be a Caribbean writer - looking back to a colonial past, and forward to a global future. This audio recording is part the Interviews on Great Writers series presented by Oxford University Podcasts.

This presentation aims to increase the students’ knowledge about environmental epidemiology, by introducing different study designs used to study health effects of exposure to outdoor air pollution. All study designs are illustrated by examples, starting with the Great Smog (Killer Fog) of London in 1952, one of the landmarks in environmental epidemiology.

Nearly one third of the world’s population are exposed to high levels of indoor air pollution from the household’s use of solid fuel. The fuel is mainly biomass burning under poor combustion conditions
in open fires or primitive stoves and with low ventilation. This costs more than 4 million lives every year and enormous suffering in particular among women and children.

What is air pollution? What is it in the air that is harmful? This lecture focuses on air pollution, where it occur, and how it spread.

In this presentation, we will describe the global levels and trends in major air pollutants and related health burden. Air pollution is an important global risk factor for disease. People who live in more polluted areas develop more often chronic and infectious disease and die prematurely as compared to people living in areas with low air pollution.

In large part of the World, people spend more than 90 percent of the time in indoor environments, where air quality is important for health. The environment outside the building, what goes on inside the building and the exchange of air pollutants affects the indoor air. Tight buildings can reduce energy consumption and entry of outdoor air pollutants, but unless ventilation is right indoor air pollutants from combustion processes, dampness, microbes, the dwellers bio effluents,
appliances, care and cleaning products, clothing, furniture, building materials, the underground and many other sources will build up indoors causing important health effects.

In this presentation, we will discuss how we can know whether one individual is more susceptible to harmful effect of air pollution than others are. Everyone is exposed, but some groups may be more susceptible to the harmful effect of air pollution than others may.

In this lecture, we will describe the mechanisms by which air pollution causes pulmonary health effects in the human population. The pulmonary health effects include exacerbation of asthma and chronic obstructive pulmonary diseases (COPD), increased risk of lower
respiratory tracts infections and lung cancer.

In this presentation, we will describe the mechanisms by which air pollution causes health effects in other parts of the body than the lungs. In continuation of this, we will discuss the important mechanisms of extra pulmonary health effect.

There is a long way before the whole world complies with the WHO guidelines for air quality, but the enormous burden of disease from outdoor air pollution forces us to increase action to come as far as possible. In continuation of this, we will discuss what we can do about air pollution at global, international, national, city and individual levels. Most of the actions to reduce air pollution also mitigates climate change and/or promote health in other ways – so there are many win-win and
win-win-win situations

This course treats various methods to design and analyze datastructures and algorithms for a wide range of problems. The most important new datastructure treated is the graph, and the general methods introduced are: greedy algorithms, divide and conquer, dynamic programming and network flow algorithms. These general methods are explained by a number of concrete examples, such as simple scheduling algorithms, Dijkstra, Ford-Fulkerson, minimum spanning tree, closest-pair-of-points, knapsack, and Bellman-Ford. Throughout this course there is significant attention to proving the correctness of the discussed algorithms. All material for this course is in English. The recorded lectures, however, are in Dutch.

The United States was founded on the principles of natural rights, equality, and classical republicanism, but how well did it actually live up to these ideals? In this lecture, Professor Rob McDonald of the US Military Academy at West Point describes the conflict between the ideals of the American Revolution and the unfortunate realities of the time.

In "The American Novel Since 1945" students will study a wide range of works from 1945 to the present. The course traces the formal and thematic developments of the novel in this period, focusing on the relationship between writers and readers, the conditions of publishing, innovations in the novel's form, fiction's engagement with history, and the changing place of literature in American culture. The reading list includes works by Richard Wright, Flannery O'Connor, Vladimir Nabokov, Jack Kerouac, J. D. Salinger, Thomas Pynchon, John Barth, Maxine Hong Kingston, Toni Morrison, Marilynne Robinson, Cormac McCarthy, Philip Roth and Edward P. Jones. The course concludes with a contemporary novel chosen by the students in the class.

The American Revolution entailed some remarkable transformations -- converting British colonists into American revolutionaries, and a cluster of colonies into a confederation of states with a common cause -- but it was far more complex and enduring then the fighting of a war. As John Adams put it, "The Revolution was in the Minds of the people . . . before a drop of blood was drawn at Lexington" -- and it continued long past America's victory at Yorktown. This course will examine the Revolution from this broad perspective, tracing the participants' shifting sense of themselves as British subjects, colonial settlers, revolutionaries, and Americans.

Have you ever stopped to think about the incredible risks the Founding Founders took when they rebelled against British authority? They were starting a war with the greatest military power of the time even though they did not have a mighty fighting force themselves. And they were fighting for a type of government that most people thought was impossible. In this video mini-course, Professor Sarah Burns of the Rochester Institute of Technology explains the historical and philosophical context of the American Revolution from the changing role of the British army in the colonies to Radical Whig theory.

This presentation offers an overview of the developing concept of The Anthropocene -- a term coined to describe our current geological epoch, in which human impact on the planet will leave a permanent trace.

Each lecture in this series focuses on a single play by Shakespeare, and employs a range of different approaches to try to understand a central critical question about it. Rather than providing overarching readings or interpretations, the series aims to show the variety of different ways we might understand Shakespeare, the kinds of evidence that might be used to strengthen our critical analysis, and, above all, the enjoyable and unavoidable fact that Shakespeare's plays tend to generate our questions rather than answer them.
