AbstractThe chemical compositions of external galaxies are usually found from their HII regions or composite absorption line spectra of their nuclei. In the Magellanic Clouds, however, individual stars are observable, but objects heretofore studied necessarily have been luminous la supergiants which border on the brink of instability. The image photon counting system on the Anglo-Australian Telescope makes it possible to observe fainter, more stable Ib supergiants. Energy distributions and Balmer line profiles for these stars can be fitted with theoretical predictions by Kurucz. A joint effort by J.E. Ross and B.J. O’Mara of the University of Queensland, Bruce Peterson of the Anglo-Australian Observatory, and a group at the University of California, Los Angeles to analyze three lb supergiants suggests that metals of the iron group are depleted by a factor of 2-3.5 with respect to the normal chemical composition of our own galaxy.

A radiocarbon facility has been installed at the University of California, Riverside (UCR) to support interdisciplinary studies including archaeologic, archaeometric, geophysical, and geologic research. The laboratory was built between 1970 and 1973. Initially, a sample pretreatment and combustion system designed for a proportional CO2 counting system was installed. It was designed after concepts developed at the University of California Los Angeles (UCLA) and New Zealand (Institute of Nuclear Sciences) Laboratories, and began processing samples in November 1972.

The California missions, whose original church spaces and visual programs were produced by Iberian, Mexican, and Native artisans between 1769 and 1823, occupy an ambiguous chronological, geographical, and political space. They occupy lands that have pertained to conflicting territorialities: from Native nations, to New Spain, to Mexico, to the modern multicultural California. The physical and visual landscapes of the missions have been sites of complex and often incongruous religious experiences; historical trauma and romantic vision; Indigenous genocide, exploitation, resistance, and survivance; state building and global enterprise. This Dialogues section brings together critical voices, including especially the voices of California Indian scholars, to interrogate received models for thinking about the art historical legacies of the California missions. Together, the contributing authors move beyond and across borders and promote new decolonial strategies that strive to be responsive to the experience of California Indian communities and nations. This conversation emerges from cross-disciplinary relationships established at a two-day conference, “‘American’ Art and the Legacy of Conquest: Art at California’s Missions in the Global 18th–20th Centuries,” sponsored by the Terra Foundation for American Art and held at the University of California, Los Angeles, in November 2019.

The May Fourth Movement

Timothy Weston's study of Beijing University (hereafter, “Beida”) spotlights how modern Chinese intellectuals positioned themselves politically and socially in the early 20th century. Weston relies on the Beida archives, dailies, journals, and many other sources, to make four contributions. First, Beida's early history shows how literati humanists repositioned themselves during a period of great uncertainty. New style intellectuals had influence because they mastered Western and classical learning. Secondly, Beida's complex history did not break sharply with the past. Earlier accounts of the May Fourth movement obscure the efforts of intellectuals since 1898 to redefine their role. Weston suggests that May Fourth amplified a continuing progression of new and old ways of doing things. Thirdly, political tensions emerged when the university increasingly radicalized after 1911. No more than 20 per cent of Beida students were involved in the New Culture movement. A strong conservative undertow continually challenged radical agendas. Often we hear only the voices of the latter. Finally, Weston assesses Beida's history in light of how the May Fourth movement played out in different locations. In the 1920s, Shanghai replaced Beijing as the leading venue for urban China's cultural and intellectual leaders. Beijing increasingly lost status under warlordism, and the Nationalist shift of the capital to Nanjing refocused Chinese intellectual life on the Chang (Yangtze) delta.

Effective Temperatures

The use of photometric and spectroscopic criteria, calibrated by model-atmosphere calculations, for determining effective temperatures, surface gravities and chemical compositions of stars is illustrated and commented on. The accuracy that can be obtained today in such calibrations is discussed, as well as possible ways of improving this accuracy further for different types of stars.
