Matthew Luckiesh
Matthew Luckiesh DSc, DE, (September 14, 1883 Maquoketa, Iowa – November 2, 1967 Shaker Heights, Ohio) was a physicist and, as the Director of General Electric's Lighting Research Laboratory at its Nela Park National Lamps Works facility in East Cleveland, Ohio, he pursued research on light and vision. In his day, he was known as the "Father of the Science of Seeing." Luckiesh developed several theories on color and its physiological effect on people. He was also interested in determining the conditions under which optimal visibility was achieved, and in examining the relationship between light and seeing, in order to design better types of lamps. During World War I he studied camouflage, and later invented artificial sunlight and germicidal lamps. Luckiesh produced eleven U.S. patents, 28 books and about 860 scientific and technical articles, published between 1911 and 1960. Asked how to say his name, he told ''The Literary Digest'' "My name is pronounced as if it were spelled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Socioeconomic Status
Socioeconomic status (SES) is a measurement used by economics, economists and sociology, sociologsts. The measurement combines a person's work experience and their or their family's access to economic resources and social position in relation to others. In common parlance, "socioeconomic status" is synonymous with social class. However, academics distinguish social class from socioeconomic status, using the former to refer to one's relatively stable cultural background and the latter to refer to one's current social and economic situation which is consequently more changeable over time. When analyzing a family's SES, the household income and the education and occupations of its members are examined, whereas for an individual's SES only their own attributes are assessed. Recently, research has revealed a lesser-recognized attribute of SES as perceived financial stress, as it defines the "balance between income and necessary expenses". Perceived financial stress can be tested by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanford Achievement Test Series
The Stanford Achievement Test Series, the most recent version of which is usually referred to simply as the "Stanford 10" or SAT-10, is a set of standardized test, standardized achievement tests used by school districts in the United States and in American schools abroad for assessing children from kindergarten through high school. Millions of students have taken the test each year. First published in 1922, the test is now in its tenth version. It is produced by the publishing company Harcourt (publisher), Harcourt (now owned by Pearson PLC, Pearson), and should not be confused with the SAT college admission test published by the College Board. Although in many states it is being replaced by state-created tests (mandated by the No Child Left Behind Act of 2001), it is not equivalent to most of these tests in that the Stanford series are more comprehensive in scope than the newer assessments. The test is available in 13 levels that roughly correspond to the year in school, but the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tungsten
Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternative name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at . It also has the highest boiling point, at . Its density is 19.254 g/cm3, comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work into metal. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many alloys ...

Literary Digest
''The Literary Digest'' was an American general interest weekly magazine published by Funk & Wagnalls. Founded by Isaac Kaufmann Funk in 1890, it eventually merged with two similar weekly magazines, ''Public Opinion'' and '' Current Opinion''. The magazine gained notoriety when its poll of the 1936 United States presidential election substantially missed the final result, predicting a landslide victory for Republican candidate Alf Landon over Democratic incumbent President Franklin D. Roosevelt: in the election, Roosevelt defeated Landon in an unprecedented landslide. The magazine ultimately ceased publication in 1938.

Established as a weekly newsmagazine, it offered condensations of articles from American, Canadian and European publications. Type-only covers gave way to illustrated covers during the early 1900s. After Isaac Funk's death in 1912, Robert Joseph Cuddihy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
