Human and Artificial Agent's Conversations on the GRID
This position paper supports a conversational and social view of future e-Learning activities on the GRID. This evolution of the Web seems to be nicely synergic with current developments in Agents and Agent Communication Languages. Exactly what e-Learning needs in order to go over from a multimedia-based, passive or at best retroactive view of e-Learning resources to a proactive, peer-to-peer approach of social conversations among human and (progressively) artificial autonomous Agents.
How GRID could improve E-Learning in the environmental science domain
This paper will outline the requirements for an interactive e-learning system defined as part of the German research project GIMOLUS . After a short overview over the Open Grid Service Architecture (OGSA) it will be shown that the capabilities of existing e-learning solutions are too limited in order to fulfil these requirements. The last part will show how a GIMOLUS system could be built using a GRID service architecture and what the benefits are in doing so.
Resource-adaptive Selection of Strategies in Learning from Worked-Out Examples
Most tasks can be pursued by using different strategies (Logan, 1985; Reder & Schunn, 1998). In this paper we focus on strategies of learning from worked-out examples. Within a resourceoriented framework these different strategies can be classified according to their costs and benefits. These features may determine which strategy will be selected for accomplishing a task in situations with certain resource limitations. We investigate specific hypotheses about strategic adaptations to resource li
Kaleidoscope JEIRP on Learning Patterns for the Design and Deployment of Mathematical Games: Final R
Over the last few years have witnessed a growing recognition of the educational potential of computer games. However, it is generally agreed that the process of designing and deploying TEL resources generally and games for mathematical learning specifically is a difficult task. The Kaleidoscope project, "Learning patterns for the design and deployment of mathematical games", aims to investigate this problem. We work from the premise that designing and deploying games for mathematical learning re

Dancing after Dark: A Rural Woman Recalls Farm Life in the Early 20th century
Although we sometimes think of farm and factory as antithetical, many people moved easily between the two. Icy Norman grew up in North Carolina, the daughter of a miner. As a young woman she worked long hours in a textile mill, but she also helped with the farm chores, especially seasonal chores like the corn shucking described here. In this excerpt from a 1979 interview conducted by the Southern Oral History Program at the University of North Carolina, she recalled family and friends rolling up
Ballad to a Massacre: Private Prather's Portrait of Wounded Knee
In 1888 Plains Indians enacted a religious ritual seeking delivery from white domination, which took the form of a five-night dance (dubbed the "Ghost Dance" by whites). Two years later, the U.S. Army extinguished this vision of hope and defiance at the battle at Wounded Knee Creek on December 29, 1890. W. H. Prather, an African-American private in the Ninth Cavalry and the regimental poet, wrote "The Indian Ghost Dance and War," which recounted in ballad form the military's perspective on the m
"The Baby Was Made 'Delegate No. 800'": Frances Willard Meets Elizabeth Rodgers in the 1880s
The commitment of the Knights of Labor to equality for women was more than rhetorical, as seen in the career of Elizabeth Rodgers, the Master Workman, or head, of the organization's giant Chicago District No. 24. This 1889 portrait of Rodgers, offered by leading national anti-liquor activist Frances Willard, underscored the desire on the part of many Knights, both men and women, to connect the struggle for labor reform with a broader vision that included vehement opposition to liquor. It also sh
"Organize among Yourselves": Mary Gale on Unemployed Organizing in the Great Depression
The Communist-led Unemployed Councils were the first and the most active of the radical movements that sought to mobilize the jobless during the Great Depression. In this interview, which is taken from the radio series "Grandma Was an Activist," relief worker Mary Gale, who was sympathetic to radicals and the jobless, described how she worked behind the scenes to encourage her clients to organize and demand better treatment. The jobless and the poor had few advocates for them, and radicals like
Kissing Rudy Valentino: A High-School Student Describes Movie Going in the 1920s
Fears about the impact of movies on youth led to the Payne Fund research project, which brought together nineteen social scientists and resulted in eleven published reports. One of the most fascinating of the studies was carried out by Herbert Blumer, a young sociologist who would later go on to a distinguished career in the field. For a volume that he called Movies and Conduct (1933), Blumer asked more than fifteen hundred college and high school students to write "autobiographies"of their expe
"I Am Obliged to Reside in America": A Gay Immigrant Tells His Story in 1882
The reasons immigrants had for leaving their homelands and coming to America were as diverse as the backgrounds of the immigrants themselves. Although most immigrants came to the United States for economic reasons some sought a new home because of persecution based on their politics, religious beliefs, or even their sexual orientation. In this 1882 letter sent to medical writer and sexologist Dr. Richard von Krafft-Ebing, a thirty-eight-year-old German-born merchant explained how a homosexual ar
Super Bowl parties and alcohol
For Americans, Super Bowl Sunday means laughter, cheering, camaraderie, plenty of food and for many -- alcohol. Watching sporting events and consuming alcohol go hand-in-hand, and this year is likely to be no different. But if you plan to imbibe, you could be contributing to a serious public health risk. University of Minnesota School of Public Health expert Darin Erickson offers some tips on a successful Super Bowl Sunday that includes alcohol
"Everything Was Lively": David Hickman Describes the Prosperity Late Nineteenth-Century Railroads Br
The availability of rail connections often determined whether a western community would survive or die. The rails fostered prosperity by bringing both goods and people. This trade, and the local service industries that sprouted up to capitalize on the movement of people and goods, drove many local economies. Here, David Hickman talked about the boom years that followed the arrival of the railroad in the Latah County, Idaho town of Genesee in the 1880s.
Breaking down Super Bowl advertising
Why is a 30-second commercial in Sunday's Super Bowl worth $3 million? How can viewers score the advertising winners and losers? And what role will social media play in the marketing game plan this year? University of Minnesota Carlson School of Management professor George John discusses these issues surrounding the "Big Game" and more.

The Other Side of the Table
Andrei Gromyko served as Soviet foreign minister from 1957 to 1985. Beginning in 1943, when Soviet premier Joseph Stalin appointed the 34-year-old ambassador to Washington, Gromyko was an indispensable formulator of Kremlin policy toward the United States. Ultimately, he dealt with nine U.S. presidents. In this video segment, Gromyko chronicles the arms race, beginning in the 1950s under General Secretary Nikita Khrushchev. At the time, each superpower had the ability to inflict "unacceptable da
Germans to the Front
General Gerd Schmuckle served in the Federal Republic of Germany's Ministry of Defense from 1956 to 1962 under defense minister Franz Josef Strauss. Strauss was charged with building up the Bundeswehr, the newly formed federal armed forces. In this video segment, Schmuckle describes Germany's reaction to the U.S. doctrine of massive retaliation, which de-emphasized a conventional buildup-one that Germans advocated-and depended on thousands of nuclear warheads deployed on German soil. When French
