Corneal Ulceration in South East Asia
This dataset has been added as an experimental use of Open Context for public health data sharing applications. Corneal ulceration is a major cause of blindness in many parts of the world, but in South East Asia the WHO estimates that there are as many as 12 million blinding ulcers every year in a population of 1.6 billion.

"All These Mean Dykes Standing Around:"Shelley Ettinger Describes the Lesbian and Gay Community of t
The women's movement of the 1970's sent shock-waves through every corner of American life, transforming the way people thought about families, jobs, and every day interactions.

"Music Can Make You Feel Like You're Not Quite So Helpless:" Pete Seeger on People's Music
Pete Seeger, folksinger, songwriter, and activist, provides a remarkable link between the radical culture of the 1930's and the protest culture of the 1960's. In 1940 Seeger met Woody Guthrie and the two formed the Almanac Singers, a leftist singing group that recorded pacifist and pro-union songs.

While he lived and worked under siege for his political views during t
Nikos Valence on Organizing Against the North American Free Trade Agreement
During the 1980's and 1990's international free trade agreements encouraged by the United States government increased the power and global reach of multinational corporations. The most controversial of these agreements, the North American Free Trade Agreement (NAFTA), made it easier for U.S. companies to buy low cost goods from Mexico, which were often produced by U.S. subsidiaries that migrated to take advantage of low-cost labor. Organized labor and most liberal Democrats opposed NAFTA because
We are Told that the Americans have 13 Councils Compos'd of Chiefs and Warriors: The Chickasaws Send
The Chickasaw Indians occupied a key region of northern Mississippi. They held in check the French and Choctaws with their allies and trading partners the British. The American Revolution ended that balance of power. The Chickasaws sought neutrality but also felt allegiance to the British due to their long-held ties. In 1779, the Virginians sent threatening messages warning them of dire consequences if they did not make peace. The Chickasaw chiefs replied in a bold manner. The Mississippi River
"You are Like Women, Bare and Open, without any Fortifications": Hendrick Criticizes the British for
When the British colonial administration called a conference in Albany in the summer of 1754, the British Empire was in the midst of great change.

05 - Telling a Free Story: Fugitive Slaves and the Underground Railroad in Myth and Reality
Professor Blight discusses the rise of abolitionism. Blight begins with an introduction to the genre of slave narratives, with particular attention to Frederick Douglass' 1845 narrative. The lecture then moves on to discuss the culture in which antebellum reform grew--the factors that encouraged its growth, as well as those that retarded it.

04 - A Northern World View: Yankee Society, Antislavery Ideology and the Abolition movement
Having finished with slavery and the pro-slavery argument, Professor Blight heads North today. The majority of the lecture deals with the rise of the Market Revolution in the North, in the 1820s, 1830s, and 1840s. Blight first describes the causes of the Market Revolution--the rise of capital, a transportation revolution--and then moves to its effects on the culture and consciousness of antebellum northerners. Among these effects were a riotous optimism mixed with a deep-rooted fear of change, a

eBird's goal is to maximize the utility and accessibility of the vast numbers of bird observations made each year by recreational and professional bird watchers. It is amassing one of the largest and fastest growing biodiversity data resources in existence. For example, in 2006, participants reported more than 4.3 million bird observations across North America. The observations of each participant join those of others in an international network of eBird users. eBird then shares these observati
For many years scholars have recognized that late nineteenth-century Durham, North Carolina makes an ideal case study for examining emancipation, industrialization, immigration, and urbanization in the context of the New South. "With its tobacco factories, textile mills, black entrepreneurs, and new college," the historian Syd Nathans observes, "Durham was a hub of enterprise and hope." By the early twentieth century, Durham became renowned for its vibrant entrepreneurial spirit. Both W.E.B. Du
Calculus Conversations: Making Student Thinking Visible
The difficulty that many calculus students face is their inability to apply methods and concepts used in practiced problems to new situations. This is not only a cause for concern in their calculus courses but also in subsequent science and engineering courses where they need to use the fundamental principles and methods of calculus. This project began as an attempt to create a course activity that would help students improve their ability to transfer their knowledge across application domains.
The people who came to California in search of gold were faced with the threat of disaster in every step of their journey. Many came by ship, even though shipwrecks were commonplace ? one set of lithographs depicts four shipwrecks that occurred within 60 days. Earthquakes were another fact of life in California. Sensational newspaper illustrations like "Earth Quakey Times," and photographs showing buildings in shambles, helped build the state's reputation as an "earthquake capital." Earthquakes
Diversity in the Changing State

Before the Gold Rush, the population consisted mainly of Native Californians and Californios (settlers and landowners of mixed Spanish, Native Californian, and African descent). But gold fever brought people to California from all over the country and world. The Anglo Americans (of English, Irish, or Scots descent), other Europeans (including Italians, Russians, and others), Chinese, Asians, African Americans, and
