We report geochemical analysis of seven rock specimens and six stone artifacts from Nihoa and Necker Islands, Hawai'i. The analyzed rock specimens exhibit chemistry consistent with published data sets and establish a major element distinction between Nihoa and Necker. Their trace element data indicate that the analyzed rocks and artifacts are local in origin and they reliably discriminate from sources on Kaua'i. These preliminary results support Emory's thesis that early (archaic) Hawaiian colonists on Nihoa and Necker relied on their local basaltic stone to manufacture stone tools, containers, and other portable objects. 相似文献

Optically stimulated luminescence (OSL) is applied to quartz extracted from mud mortar collected from Chavín de Huántar, an
early Andean monumental center. The samples appear to have been only partially exposed to sunlight during construction, so
a minimum age model is applied to equivalent dose distributions. Complications, including complex radioactivity, low sensitivity
of the quartz, and limited sample, prevent high precision, but the 14 dates obtained cluster around 1000 BC largely in agreement
with radiocarbon assays on charcoal also collected from the mortar. Results suggest a relatively rapid construction for the
monument. This work develops OSL as a method for directly dating architectural mortar. 相似文献

Environmental policymaking has remained an important issue in American public policy for many years. While many individuals have proenvironmental attitudes, they remain unwilling to take the actions necessary to achieve environmental goals. Many variables have been used to explain support for environmental policymaking. This study looks at the effect of uncertainty about environmental quality, perception of risk from environmental hazards, and trust in government and university scientists on willingness to take environmental action. The study examines the impact of these three variables on two environmental issues—tap water and nuclear power. The data were collected from a national sample of 400 individuals. This article presents the results of this research and examines the complex relationships among risks, trust, uncertainty, and willingness to take environmental action. The conclusions improve our understanding of environmental attitudes as well as have practical implications for policymakers who need to build public support for policies designed to improve the environment. 相似文献

Landscape-based planning, and in particular ecosystem management, has been promoted widely as an approach to linking ecological, social, and economic concerns at large spatial and temporal scales, yet there have been few comparative studies of actual projects. We used a mailed questionnaire and four case studies within the Pacific Northwest region of the United States to explore the ways in which ecological analyses are being integrated with landscape planning projects and to identify linkages between science and public involvement. Specifically, we wanted to learn: (a) what types of ecological science are being used in landscape-based planning projects, (b) what factors most limit the application of ecological analyses to land planning processes, (c) how ecological information and analyses are being integrated with stakeholder participation, and (d) what appear to be the key strategies for developing productive links between ecological science and public involvement. Results from the questionnaire show the ecologichl complexities of attempting to manage large landscapes, exemplified by the broad array of ecological issues and stressors that projects attempt to address, the high degree to which they are attempting to analyze them scientifically, and the wide array of assessments and analytical techniques they are using to do so. While both public involvement and scientific research generally had strong influences on planning and management decisions, there appeared to be less effective exchanges between researchers and stakeholders. Based on the case studies, we identified key strategies for strengthening the links between ecological science and public involvement in three principal areas: ecosystem analysis, linking science to the public via community outreach and education, and employing economic development as an ecosystem restoration and management strategy. To implement these strategies requires reconceptualizing the roles of both scientists and stakeholders so as to improve the integration of applied ecological science with democratic decisionmoting. 相似文献

This commentary looks at two related themes. Is “resistance” simply a matter of inertia or of reaction to new forces, and are resisting people purely passive or do they actively make their own history? Second, are the meanings of material culture passively assigned or are they more complex? In short, are both people and things “mute passive objects”? It is suggested that our theoretical treatment of people and of things are linked, and that further critical analysis of that linkage is needed. 相似文献

This article analyses recent federal debates regarding gay and lesbian issues, focusing on the Howard government, and drawing attention to the arguably heteronormative nature of many politicians' views. Policy issues analysed include assisted reproductive technology, superannuation rights and censorship. Reference is also made to the Justice Kirby controversy. The article explores the way in which heteronormative arguments not only construct heterosexual citizens as the norm but are also used to discount arguments that discrimination against gay and lesbian citizens is taking place. 相似文献

From uncertain origins in the spring of 1918, an apparently new variant of influenza A virus spread around the world as three distinct diffusion waves, infecting half a billion and probably killing around 40 million people. This paper examines the spatial structure of influenza transmission during the ten–month course of the epidemic in England and Wales, June 1918–April 1919, using the weekly counts of influenza deaths in London and the county boroughs as collated by the General Register Office, London. In addition, a particular case study of the borough of Cambridge is presented. From mid–1916, Cambridge contained, as well as its undergraduate population, a large naval contingent billeted in both the colleges and the town. It therefore affords the opportunity of studying the effect of the epidemic in contiguous groups with widely differing demographic characteristics. Through the application of a range of statistical methods (average lags, correlations and regressions), it is shown that the three waves that comprised the pandemic had fundamentally different spatial and temporal characteristics. The first, moving through a population that was a virgin soil to the new virus strain, was explosive in its north to south progress across the country. The second wave was somewhat slower in its rate of diffusion and displayed a south to north drift. Finally, the third wave reverted more closely to the form of the first. The spread of all three waves, however, was underpinned by a clearly defined process of spatial contagion. The Cambridge study showed the special characteristics of this pandemic in terms of the ages of those attacked: high rates were experienced across the age spectrum, a feature also seen internationally. 相似文献
