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.

3-part lecture series given at Kwame Nkrumah University of Science and Technology about infections with Gram-negative obligate anaerobes

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.

What happens when governments default on their debts? In this video, Professor Garrett Jones of George Mason University uses the Greek government debt crisis to explain what happens when governments default on their debts and why it's not always a bad thing.

Aswaat Arabiyya is an archive of 245 videos in Arabic, listed by difficulty level and accompanied by glossaries and four worksheets each that focus on every aspect of listening comprehension. Selections come largely from Arabic media, with some cultural presentations by native speakers. Videos cover the entire Arabic-speaking world and include MSA and different dialects. Materials are designed to be used both as in-class activities and homework assignments. Videos can be slowed down.

How should we understand Ayn Rand’s political philosophy? In this video, Professor Jennifer Burns of the University of Virginia argues that Rand belongs to the classical liberal tradition.

In this presentation, we talk about adaptation and evolution of bacteria. Furthermore, we will discuss how you can work with or against evolution, regarding the treatment of bacteria and biofilms.

In this presentation, we will discuss how bacterial pathogen adapt to the human host environment during long-term chronic infections. In continuation of this, we will discuss how the opportunistic pathogen - Pseudomonas aeruginosa - evolves during adaptation to the airways of cystic fibrosis patients.

This presentation introduces bacteria and biofilms. Where do we find bacteria? Is it possible to live without bacteria? Should we be scared of bacteria?

The aim of this presentation is to expand the student knowledge about biofilm properties. In continuation of this, we will present different models for testing and study a biofilm, hereby: the crystal violet assay, filter biofilm, the semi solid model, and the flow-cell system

this presentation focuses on host response to biofilm infection. In continuation of this, we will go through the different types of host response to infections, which consists of at least three components: the non-inflammatory defense, the immune response and the inflammatory response.

In this presentation we will focus’ on host response to chronic infections. In continuation of this, we will talk about the polymorphonuclear leukocytes (PMNs), the respiratory burst and reactive oxygen species (ROS).

this presentation focuses on the problems of treating chronic infections. Furthermore, we will discuss why the host defense seems to be not working probably. In continuation of this, we will discuss whether the problem with chronic infections will increase over the years.

In this presentation, we will introduce the mechanisms involved in the tolerance of biofilms to antibiotics. In continuation of this, we will talk about specific tolerance mechanism, oxidative stress and the development of mutational resistance.

This presentation introduces chronic wounds and the non-healing properties of these. In continuation of this, we will provide a brief introduction to bacterial biofilms in chronic wounds, furthermore we will introduce some of the controversies and challenges we face working with this subject.

The aim of this presentation is to expand the students’ knowledge about the chronic lung infection, Cystic Fibrosis. Cystic Fibrosis is probably the most studied biofilm infection and much of our biofilm knowledge derive from this disease.

In this presentation, we will talk about diagnosis of bacteria and chronic infections in clinical practices. We will discuss why we need to diagnose bacteria in infections and what the biggest challenges are in diagnosing bacterial and chronic infections. Finally, we will discuss what the future will bring, regarding bacteria and diagnosis.

In this presentation, we will introduce the student to diagnosis of chronic infections. Diagnosing chronic infections is just as complicated as treating these infections. In continuation of this, we will talk about the three main issues when diagnosing chronic infections and share some experiences we have within this area.

In this presentation, we will introduce you to evolution in biofilms and chronic infections. The general principles of evolution are independent of the specific environment, however some conditions related to time and space are faced by bacteria in chronic infections - and this affects evolution

In this presentation, we will tell you about social evolution in microbes and in continuation of this discuss why social evolution in microbes is important in biofilms.

In this presentation, we will discuss how bacteria are causing disease. Furthermore, we will introduce the student to the term pathogenesis, and in continuation of this present the four main steps, that causes pathogenesis.
