n late June 1863, more than two years into the American Civil War, Union and Confederate military forces converged on the town of Gettysburg, Pennsylvania. After a series of military successes, Confederate Commander Robert E. Lee led his Army of Northern Virginia into Union territory in his second invasion of the North. He hoped that a Confederate victory in Pennsylvania would convince Northern politicians to abandon the war. The Union Army of the Potomac, led initially by General Joseph Hooker and then General George Meade, crossed the Potomac River to pursue Lee’s forces.

The Bureau of Economic Analysis (BEA) produces two measures of national output which, in theory, should be equivalent. In practice, however, there are often substantive differences.

Born in Slavery: Slave Narratives from the Federal Writers' Project, 1936-1938 contains more than 2,300 first-person accounts of slavery and 500 black-and-white photographs of former slaves. These narratives were collected in the 1930s as part of the Federal Writers' Project (FWP) of the Works Progress Administration, later renamed Work Projects Administration (WPA). At the conclusion of the Slave Narrative project, a set of edited transcripts was assembled and microfilmed in 1941 as the seventeen-volume Slave Narratives: A Folk History of Slavery in the United States from Interviews with Former Slaves. In 2000-2001, with major support from the Citigroup Foundation, the Library digitized the narratives from the microfilm edition and scanned from the originals 500 photographs, including more than 200 that had never been microfilmed or made publicly available. This online collection is a joint presentation of the Manuscript and Prints and Photographs divisions of the Library of Congress.

The human brain is responsible for all behaviors, thoughts, and experiences described in this textbook. This module provides an introductory overview of the brain, including some basic neuroanatomy, and brief descriptions of the neuroscience methods used to study it.

Join us for this webinar to hear how colleges are transitioning from individual faculty OER course adoptions to entire departments and OER degree pathways. OER leaders at colleges who have reached critical mass in their implementation will share best practices for sustaining faculty engagement, student involvement, project funding, and institutional commitment to OER adoption for the enhancement of teaching and learning.

Our featured speakers are both longtime community college leaders in the OER movement at regional and district levels. They will engage each other in discussions on the themes mentioned above and invite questions from webinar attendees.

Faculty who are new to OER may experience difficulty finding an open textbook or other openly licensed materials to adopt for their courses. Searching on your own is time consuming and the choices can be overwhelming. We will hear from a college librarian who helps faculty find and adopt high quality OER to match their course outcomes and the creators of the award winning OER Commons, a freely accessible online library that allows teachers and others to search and discover open educational resources (OER) and other freely available instructional materials.

Age-related declines in capabilities may compromise older adults’ ability to maintain their homes thus threatening successful aging in place. Structured interviews were conducted with forty-four independently living older adults (Mage = 76.1, SD = 4.7) to discuss difficult home maintenance tasks and how they managed those tasks. Solutions to managing difficulties were categorized as person-related or environment-related. The majority (85%) of responses were person-related solutions. An understanding of the specific challenges that older adults face in maintaining their homes can guide redesign efforts and interventions to effectively support older adults’ desire to age in place.

Chemical hazards and toxic substances pose a wide range of health hazards (such as irritation, sensitization, and carcinogenicity) and physical hazards (such as flammability, corrosion, and explosibility).

This page provides basic information about chemical hazards and toxic substances in the workplace. While not all hazards associated with every chemical and toxic substance are addressed here, we do provide relevant links to other pages with additional information about hazards and methods to control exposure in the workplace.

Archives Specialist Rebecca Sharp will discuss The Medical and Surgical History of the War of the Rebellion, 1861–1865. This published source contains information about Civil War medical and surgical procedures as well as case studies.

Between 1861 and 1865, the Union and Confederate navies fought for control over inland and coastal waterways. Through four years of war, the United States Navy rose to the challenge of blockading more than 3,500 miles of coastline, coordinating amphibious attacks, and bombarding coastal fortifications held by the Confederate armed forces. The ingenuity and self-sacrifice of those who served U.S. Navy throughout the Civil War ultimately ensured victory for the Union.

In the overland campaign of 1864, Lieutenant General Ulysses S. Grant with the Army of the Potomac battled General Robert E. Lee and the Army of Northern Virginia for six weeks across central Virginia. At the Wilderness, Spotsylvania, North Anna and Totopotomoy Creek, Lee repeatedly stalled, but failed to stop, Grant's southward progress toward Richmond. The next logical military objective for Grant was the crossroads styled by locals Old Cold Harbor.

Widespread media reports of local teacher shortages have become a hot topic in education since the summer of 2015. After years of teacher layoffs, districts began hiring again as the economy recovered from the Great Recession. Many were surprised to find they had serious difficulty finding qualified teachers for their positions, especially in fields like mathematics, science, special education, and bilingual education/English language development. A number of states greatly expanded emergency permits to allow hiring of untrained teachers to meet these demands—which is the classic definition of shortage. To date, however, there has not yet been a detailed national analysis of the sources and extent of these shortages, and the prognosis for the future.
