The package was written in 1996. Radio immuno assay (RIA) is a technique for measuring concentrations of antigens. Although better techniques have subsequently been developed from it, understanding RIA forms the basis for understanding these derivatives. RIA belongs to the family of competition assays which are widely used in science, medicine and related industries to measure the concentrations of biologically active molecules. This package introduces the concepts of RIA and will be useful t

Shared conceptualisations in weblogs
In this paper we investigate how conceptualisations can be identified in weblogs using language technology (automated text analysis). We focus on getting a handle on both the concepts bloggers use and the way they think these concepts are related. The analysis of these conceptualisations can then be applied to a single weblog, resulting in a visualisation of potential conceptualisations the blogger wants to share with the outside world. Another type of analysis is to determine the overlap, or sh
"A Traitor to the Movement"?: A Former SDS and Women's Liberation Activist Testifies before Congress
Students for a Democratic Society (SDS) was founded in 1962 to change the world by fostering participatory democracy and personal authenticity. Heavily influenced by civil rights organizations, SDS initially operated in inner cities and college campuses to combat racism and discrimination. By the mid-1960s, many activists focused on antiwar activities as American troop involvement in Vietnam escalated. Frustrated with male domination in SDS, leftist women formed feminist splinter groups that eve
"A Rale Boost to Lithrachoor": A Humorist Lampoons Libraries
The founders of the great libraries of the 19th century were often ambivalent about whether their goal was to disseminate or conserve knowledge. They were also uncertain about the intended audience. John Cotton Dana of the Newark Public Library was atypical in his populist stance that "it is a proper function of a library to amuse." He argued that a "shallow mind" was better than an "empty one." Other librarians preferred to see themselves as cultivators of public taste and their buildings as up
A German Jewish Woman Settles in North Dakota
Women who settled the West in the years after the Civil War often faced harsh and unremitting toil. Laboring from well before dawn until well after the sun had set, women helped plant and harvest crops, raised large families, and kept house with the most rudimentary of equipment. Long periods of isolation from neighbors and kin were common; social occasions or visits by travelers and kin were rare and cherished events. Sarah Thal, a German Jew who immigrated to North Dakota in 1882, recalled tha
"A German Beer Garden on Sunday Evening."
Between 1820 and 1860, 1,500,000 immigrants arrived in America from Germany. Many of the new arrivals who settled in cities such as New York worked as shopkeepers and skilled tradesmen, although many more worked as employees in construction, brewing, and manufacturing. Although German immigrants did not mix politics and liquor, reformers were disconcerted by the atmosphere of their social establishments. Unlike the bars in Irish neighborhoods, the beer gardens catered to whole families. As this
"A Damaging Impression of Hollywood Has Spread": Movie "Czar" Eric Johnston Testifies before HUAC
The House Committee on Un-American Activities (HUAC) held hearings in October 1947 on Communist activity in Hollywood. In the following testimony, Eric Johnston, a successful businessman who in 1945 succeeded Will H. Hays as President of the Motion Picture Association of America--the industry's institution for self-regulation--defended Hollywood against HUAC's attacks and complained vigorously that the "atmosphere of fear" resulting from the investigation precluded the production of "good and ho

Middle School Portal: Math and Science Pathways (MSP2)
With this online activity, students explore the classic mathematics map-coloring question known as the four-color problem. Students must determine the minimum number of colors needed to color a map so that entities sharing a border have different colors. Initially, students investigate the minimum number of colors necessary to color a map of states west of the Mississippi River. The activity's Getting Started section suggests coloring the states in a specific order. The Solution page uses odd an
Middle School Portal: Math and Science Pathways (MSP2)
This online activity offers students a chance to apply the concept of symmetry to a real archaeology question. The activity calls for a hands-on solution to the initial challenge of determining the size of a plate from only a fragment or shard. Related math questions offer the opportunity to think about lines of symmetry for a variety of shapes. The activity is one of 80 mathematical challenges featured on the Figure This! web site, where real-world uses of mathematics are emphasized. The activi
Carbonated Grape Salad with Goat Cheese
What else can you do with a fresh table grape besides eat it? Chefs active in the realm of molecular gastronomy are manipulating ingredients in ways never imagined. Chef Scott Samuel of the Culinary Institute of America was asked to develop some contemporary recipes with California Table Grapes. He challenged himself to probe this frontier. "The idea came from one of my colleagues," says Samuel, "You put the grapes in a whipping-cream canister with wine and then charge it. You have to prick the
Buckaroos in Paradise: Ranching Culture in Northern Nevada, 1945-1982
The Buckaroos in Paradise Collection presents documentation of a Nevada cattle-ranching community, with a focus on the family-run Ninety-Six Ranch. The documentation was largely the work of the Paradise Valley Folklife Project (1978-1982), a research initiative conducted by the American Folklife Center at the Library of Congress. This collection presents 41 motion pictures and 28 sound recordings that tell the story of life and work on the Ninety-Six Ranch and of its cowboys, known in the region
