"A Sweepstakes Attracts Attention": Corporate Executives Defend Sweepstakes Promotions
In the 1960s, lottery-like contests designed to publicize products through sweepstakes competitions spread rapidly. In the 19th century, every state banned lotteries--defined as competitions in which chances to win prizes were sold÷to protect citizens. In 1868, Congress prohibited the distribution of lottery materials through the mail. The mid-20th century sweepstakes, however, did not require contestants to purchase tickets or products to win prizes and were thus considered legal. In 1966, the

Investigating multimodal interactions for the design of learning environments: a case study in scien
This thesis focuses on multimodal interactions for the design of a learning environment. The process of designing such systems involves studying the benefits of multimodal interactions in learning. Therefore, it analyses the structure of the interactive space between the learner and the content to be learnt, and introduces and tests a framework to structure it. It proposes that multimodal interactions can encourage rhythmic cycles of engagement and reflection that enhance learners’ meaning con

Growth of Cities
Cities up and down the state of California grew rapidly during the Gold Rush era. Some of these cities were veritable boomtowns: San Francisco, a small village in 1847, was a bustling city by 1849, just two years later. San Francisco's population boom even had an impact on its geography. One image from 1847 shows Montgomery Street on the waterfront; but a photograph taken in 1862 shows that the waterfront had been filled to increase the city's real estate, pushing Montgomery Street inland.
