Electroluminescence (EL) is the emission of light generated from the radiative recombination of electrons and holes electrically injected into a luminescent semiconductor. Conventional EL devices are made of inorganic direct-bandgap semiconductors, such as GaAs and InGaAs. Recently EL devices based on conjugated organic small molecules and polymers have attracted increasing attention due to easy fabrication of large areas, unlimited choice of colors, and mechanical flexibility. Potential applications of these organic/polymeric EL devices include backlights for displays, alphanumeric displays, and high-density information displays.Electroluminescence from an organic material was first demonstrated in the 1960s on anthracene crystals by Pope et al. at New York University. Subsequently several other groups also observed this phenomenon in organic crystals and thin films. These organic EL devices had high operating voltages and low quantum efficiency. Consequently they did not attract much attention. In 1987 a breakthrough was made by Tang and VanSlyke at Eastman Kodak who found that by using multilayers of sublimated organic molecules, the operating voltage of the organic EL devices was dramatically reduced and the quantum efficiency was significantly enhanced. This discovery touched off a flurry of research activity, especially in Japan. The Japanese researchers, as welt as the group at Kodak, have since improved the device efficiency and lifetime to meet commercial requirements. This progress is reviewed by Tsutsui in this issue.

The mission of the University of Hawai’i at Tell Timai in 2009 began excavating the remains of a limestone temple foundation platform in the north-west area of the site. The foundations had been partially recorded in survey work conducted in 1930 by Alexander Langsdorff and Siegfried Schott, and again in the 1960s by New York University, however no known investigations of the structure were conducted. In 2017 as part of an Egypt Exploration Society Fieldwork and Research Grant, excavations were renewed to finalise the understanding of the temple’s construction techniques, and the date of the temple. The foundations were of a casemate design with internal fills of alternating silt and limestone chips. The ceramic evidence from within the construction fills dates its construction from the end of the Ptolemaic to the early Roman Period, and the temple’s superstructure was most likely taken down and the blocks reused in the late Roman Period (fourth to fifth century ce).

When Professor Benjamin Parke De Witt of New York University sat down to write the first history of the progressive movement in 1915, he promised “to give form and definiteness to a movement which is, in the minds of many, confused and chaotic.” Apparently it was a fool's errand, because confusion and chaos continued to plague historians of early twentieth-century reform long after Professor De Witt laid his pen to rest. The maddening variety of reform and reformers in the early twentieth century has perpetually confounded historians' efforts to identify what, if anything, the progressives had in common. Back in the 1950s, Richard Hofstadter charitably allowed that progressives were “of two minds on many issues,” whereas Arthur Link argued that “the progressive movement never really existed” because it pursued so many “contradictory objectives.” In the 1960s, Robert Wiebe concluded that the progressives, if they constituted a movement at all, showed “little regard for consistency.” In the 1970s, Peter Filene wrote an “obituary” for progressivism by reasserting Link's claim that the movement had “never existed” because it was so divided and diffuse. In the 1980s, Daniel Rodgers tried to recast the “ideologically fluid” progressive movement as a pastiche of vaguely related rhetorical styles. By the 1990s, so many competing characterizations of progressivism had emerged that Alan Dawley wondered if “they merely cancel each other out.” In 2002, Glenda Elizabeth Gilmore declared emphatically that “historians cannot agree” on progressivism. In 2010, Walter Nugent admitted that “the movement's core theme has been hard to pin down” because progressivism had “many concerns” and “included a wide range of persons and groups.”
