The unit or minicours in logic so frequently favored in high schools has the laudable objective of familiarizing the student with the format of rigorous thinking. This, however, is but the bare though necessary skeleton of daily thought. Pushing the metaphor a bit, the nerve ends of the thinking person must analyze the emotional aura surrounding the ideas expressed by others. In a word, the thinking person must be able to distinguish between the form of thought (logic) and the dressing of thought (propaganda). This game, Propaganda, addresses itself to clear thinking, so that the student becomes familiar with the six major techniques of swaying the thinking of people. Each technique has at least, eight and at most ten varieties. The players (there must be two, but. better if there are more) first, learn how they fool themselves; then, they proceed to techniques of influencing others. Given concrete situations. the players seek to identify the precise variety of technique used in the propaganda statement. Twenty plays constitute a game. The winner is classified as a “clear thinker” for that, round; the loser may be anything from a “ding-a-ling” to a “Gullible Gus.” The explanation book is quite clear. The authors, Robert W. Allen of Nova School and Lorne Greene of “Bonanza” (!), have created a most useful tool for thinking one's way through the porridge of propaganda.— Barnabas B.

The Mathematics System Laboratory of the San Fernando Valley State College Trainers of Teacher Trainers Program is a special con-figuration of teachers and teacher-training personnel working in a laboratory classroom setting that, includes computer hardware and special mathematics-instruction equipment, It is designed to be housed on site at junior and senior high schools, with a flow of regular classroom students learning in new and innovative ways the mathematics curriculum of the public schools. The importance of the Mathematics System Laboratory Program lies not merely in its potential for innovation in modes of individualized mathematics instruction but in the innovative patterns of teacher training and training of teacher trainers for which the labora-tory concept calls.

Abstract Some of the largest accelerations and velocities ever recorded at ground-response and structural sites occurred during the Northridge earthquake. These motions are greater than most existing attenuation models would have predicted. Although the motions are large, the correspondence between measured acceleration and damage requires further study, since some sites with high acceleration experienced only moderate damage. Also, some peak vertical accelerations were larger than the horizontal, but in general, they are smaller and fit the pattern observed in previous earthquakes. Strong-motion records processed to date show significant differences in acceleration and velocity waveforms and amplitudes across the San Fernando Valley. Analysis of processed data from several buildings in the San Fernando Valley indicates that short-period buildings such as shear-wall buildings experienced large forces and relatively low inter-story drift during the Northridge earthquake. However, long-period (1 to 5 sec) steel or concrete moment-frame buildings experienced large inter-story drift. For this earthquake, accelerations did not always amplify from base to roof for flexible structures like the moment-frame buildings, but the displacements were always larger at the roof. The drifts at many of the moment-frame buildings were larger than the drift limit for working stress design in the building code. The records from a base-isolated building indicate that high-frequency motion was reduced significantly by the isolators. The isolators deformed about 3.5 cm, which is much less than the design displacement. The records from a parking structure show important features of the seismic response of this class of structure.

Abstract Background Globally, among a wide range of public health concerns, smoking remains one of the most crucial challenges. Especially for adolescents, the increase in the use of electronic cigarettes is controversial, as its use may lead to established smoking. In Japan, where a unique tobacco regulation system exists, the heat-not-burn tobacco market has been growing. However, the prevalence and association of combustible cigarettes and new tobacco-related products have not yet been closely investigated among Japanese adolescents. This study aimed to clarify the prevalence of smoking among adolescents including new types of tobacco-related products and to compare the characteristics of their users.Methods In 2017, a cross-sectional survey was conducted with randomly sampled junior high school and high school students from 47 prefectures nationwide. Overall, 98 junior high schools in 44 prefectures and 86 high schools in 42 prefectures were included in the survey. In total, 22,275 students from 48 junior high schools and 42,142 students from 55 high schools completed an anonymous questionnaire while at school.Results The age-adjusted rate of ever (current) use of electronic cigarettes was 2.1% (0.7%) in junior high school and 3.5% (1.0%) in high school; that of combustible cigarettes was 2.6% (0.6%) in junior high school and 5.1% (1.5%) in high school; the rate of heat-not-burn tobacco use was lower relative to the other products: 1.1% (0.5%) in junior high school and 2.2% (0.9%) in high school. Examination of the combined use of the three types of products identified a high number of dual users. Comparison between different types of users indicated different backgrounds of combustible cigarette users and new products users.Conclusions The prevalence of new tobacco-alternative products is growing in popularity among Japanese adolescents. Dual use is common, and many adolescents use new products only. Moreover, e-cigarettes might lure a broader range of groups to smoking. Continuous monitoring and further research should investigate the health impact of new products to promote public health action regarding smoking epidemics.
