Building Bridges within Learning Communities through Ontologies and "Thematic Objects"
Communication through artefacts, in the sense of objects (co-)constructed by learners, is a well known mechanism in synchronous shared workspace environments. In this article, we explore the potential of extending this principle to heterogeneous, anonymous and asynchronous learner communities by drawing on existing work, e.g. in the areas of "social navigation" and recommender systems. A new ingredient is the description and provision of "thematic objects" embedded in a task/activity context. De
Graphical Jogthrough: expert based methodology for user interface evaluation, applied in the cas
Walkthrough and Jogthrough techniques are well known expert based methodologies for the evaluation of user interface design. In this paper we describe the use of Graphical Jogthrough method for evaluating the interface design of the Network Simulator, an educational simulation program that enables users to virtually build a computer network, install hardware and software components, make the necessary settings and test the functionality of the network. Graphical Jogthrough is a furth
The use of a computerized brain atlas to support knowledge-based training in radiology
Trainers of radiologists face the particular challenges of teaching normal and abnormal appearance for a variety of imaging modalities, providing access to a large appropriately-indexed case library, and teaching a consistent approach to the reporting of cases. The computer has the potential to address these issues, to supplement conventional teaching of radiology by providing case-based tutoring and diagnostic support based on a large library of images of normal and abnormal anatomy, fully desc

A recent USGS open file report entitled Ranking of the World's Oil and Gas Provinces by Known Petroleum Volumes groups the worlds 937 geologic provinces into eight regions by known petroleum volumes of field. This site succintly describes the ranking methods used and results of the study. Perhaps not surprisingly, the Middle East and North Africa was found to contain nearly twice as many billions of barrels of oil than any other area. The researchers hope that the rankings will "facilitate studi
From MASK Knowledge Management Methodology to Learning Activities Described with IMS LD
In this paper we present how the way knowledge capitalized using the Knowledge Management Mask methodology can be used to design E-learning activities by matching Mask models and the concepts proposed by the IMS-Learning Design modelling language. Our study consists in highlighting the e-learning aspects encapsulated in these MASK models carried out around a domain of activity, via a writing these elements in the description language IMS - Learning Design; in a preoccupation of reusability and r
Theory of functions of a real variable
I have taught the beginning graduate course in real variables and functional analysis three times in the last five years, and this book is the result. The course assumes that the student has seen the basics of real variable theory and point set topology. The elements of the topology of metrics spaces are presented (in the nature of a rapid review) in Chapter I. The course itself consists of two parts: 1) measure theory and integration, and 2) Hilbert space theory, especially the spectral theorem

With the exception of orchestral performances and truly "unplugged" concerts, today's music has evolved into a very hi-tech industry. It takes elements from many disciplines, including computer science, electrical and mechanical engineering, mathematics, and physics. Because music technology encompasses everything from audio compression and encoding to advanced sound equipment, this Topic in Depth has quite a broad scope.A decent introduction to some aspects of music technology (1) mainly deals
Introduction to Vectors and Tensors, Vol. 2, Vector and Tensor Analysis

Although some might fear that limited land resources and the usual development pressures are working to reduce Britain's natural history to footnote status, this website from the Natural History Museum in London effectively documents the UK's impressive biological and geological diversity. The site consists of interactive database features as well as videos (in both Windows Media and Quicktime formats). Exploring Biodiversity, an interactive introduction for students to UK biodiversity, allows u

By participating in a game called "Barter Bag" students will be introduced to the concept of trade. This introduces students to the concept of bartering.
A Thorn in the Side: A Socialist Takes Aim at Gompers
During the 1890s, the American Federation of Labor (AFL) was faced with both the rising popularity of the People's Party in rural areas and attempts by the Populist movement to create a farmer-labor alliance. At the same time, socialist trade unionists lobbied for greater political involvement and adoption of several key socialist positions by the AFL. One of those socialist trade unionists was J. Mahlon Barnes, a Philadelphia cigar maker, member of the Cigarmakers' International Union, and memb
A Separate Peace: Alice Henry on Women and Unions
The Women's Trade Union League (WTUL), established in 1903 by reformers seeking to combine the forces of trade unionism and feminism, faced particular obstacles when organizing women into unions. In this 1915 essay, published in The Trade Union Woman, WTUL leader Alice Henry discussed some of those problems and advocated separate women's locals as a possible solution. Another important organizing problem, which Henry did not discuss, was the tension between the middle-class reformers of the WTUL
Statistics Online Computational Resource for Education and Research
The goals of the Statistics Online Computational Resource (www.SOCR.ucla.edu) are to design, validate and freely disseminate knowledge. Specifically, SOCR provides portable online aids for probability and statistics education, technology based instruction and statistical computing. SOCR tools and resources include a repository of interactive applets, computational and graphing tools, instructional and course materials. The core SOCR educational and computational components include: Distribution
A Letter Home From Massachusetts Bay in 1631
Over 20,000 migrants from England crossed the Atlantic to the new colony of Massachusetts Bay in the decade of the 1630s. This sudden influx of settlers became known to historians as the "Great Migration." Once in New England, they quickly dispersed to various towns. About forty families followed Sir Richard Saltonstall and the Reverend George Phillips four miles up the Charles River to found the community of Watertown in July 1630. Many had relocated from the East Anglian region of England, whe
"A Crowd of Howling Negroes": The Chicago Daily Tribune Reports the Chicago Race Riot, 1919
As U.S. soldiers returned from Europe in the aftermath of World War I, scarce housing and jobs heightened racial and class antagonisms across urban America. African-American soldiers, in particular, came home from the war expecting to enjoy the full rights of citizenship that they had fought to defend overseas. In the spring and summer of 1919, murderous race riots erupted in 22 American cities and towns. Chicago experienced the most severe of these riots. On Sunday, July 27, white bathers attac
A Call to Arms: McNeill's Unshakable Faith in Labor's Future
As the 19th century drew to a close, labor activists were forced to confront the implications of a long string of defeats suffered by their movement in recent years. One of the most venerable of labor editors, George McNeill, writing in the official journal of the American Federation of Labor (AFL) in December 1896, encouraged trade unionists to renew their commitment to a struggle that had not always been successful. At the same time, he accurately predicted an even more momentous battle in the
"A Black Joke."
Free African Americans living in the North before the Civil War suffered enormous disadvantages and discriminations. Forced to sit in separate and inferior sections in theaters, public transit, and churches, free blacks were also barred from all but the most menial jobs and denied entrance to white trade unions. This racist cartoon in an 1854 edition of the humor magazine Yankee Notions inadvertently illustrated the everyday harassment and cruelty to which northern African Americans were subject
