Narratives are increasingly subject to empirical study in a wide variety of disciplines. However, in public policy, narratives are thought of almost exclusively as a poststructural concept outside the realm of empirical study. In this paper, after reviewing the major literature on narratives, we argue that policy narratives can be studied using systematic empirical approaches and introduce a “Narrative Policy Framework” (NPF) for elaboration and empirical testing. The NPF defines narrative structure and narrative content. We then discuss narrative at the micro level of analysis and examine how narratives impact individual attitudes and hence aggregate public opinion. Similarly, we examine strategies for the studying of group and elite behavior using the NPF. We conclude with seven hypotheses for researchers interested in elaborating the framework. 相似文献

The publication of Galois' works in the Journal de Liouville (1846) was announced during a debate between academicians Libri and Liouville as early as 1843. Rather than limiting this publication to a study of controversy, we would like to show that it is inscribed in a larger context of the redefinition of algebra, which this debate illuminates. In order to understand the rediscovery of Galois, it must be inscribed in the median time of mathematical practices and usages. 相似文献

Large island-like shell mounds along the southern coast of Mexico are the earliest known archaeological sites on the Pacific margin of Mesoamerica. These aceramic deposits date to between 7500 and 3800 cal BP and have been interpreted as locations where foragers, living elsewhere seasonally on the coastal plain, harvested shellfish and other estuarine resources. Based on an accumulation of paleoecological data from elsewhere in the lowland Neotropics of Mesoamerica, southern Central America and South America we pose and provide a first test of an alternative subsistence model: that the Archaic Period populations in this area were slash and burn farmers. Burned maize phytoliths first appear in these sedimentary records at 6500 cal BP in association with macroscopic charcoal and forest disturbance plant taxa. Periodic burning and forest disturbance, consistent with farming activities, are also evident in the macroscopic charcoal record between 6500 and 4700 cal BP. Pollen, phytolith and charcoal records all point to sustained burning, forest disturbance and the cultivation of maize between 4700 and 3800 cal BP. These data suggest that people were slash and burn farming during the Archaic Period prior to the adoption of pottery and the proliferation of Early Formative Period villages and full-fledged agriculture based on near or total reliance on crop plants after ∼3800 cal BP. 相似文献

Frankincense burners found in al‐Shihr’s excavations in Yemen, a frankincense harbour during the Islamic period, represent a rare corpus of this type, which is an indication of both specific use and goods from South Arabia. Although associated with the pre‐Islamic South Arabian kingdoms, the frankincense burner evolved throughout the Islamic period. This is proved by the long chronological sequence of the al‐Shihr site (780–1996). Texts quoting the presence of frankincense, its use and its trade in al‐Shihr are cited in this article to support the reputation of this harbour‐town, which is part of the maritime trade networks of medieval Islam. The aim of this article is to create a renewal of interest in future archaeological research about this object, which is so often neglected in spite of its importance as a testimony of the customs and exchanges that are deeply rooted in Arabian civilisation. 相似文献

Urban (re-)development projects may generate various positive and negative spatial externalities to employers. The assessment of such benefits is fraught with many methodological and empirical problems. This study aims to assess the order of magnitude of expected net benefits for incumbent employers that may accrue from a large-scale development project in the Zuidas area in the South-Western part of Amsterdam, the Netherlands. This development project is planned to transform the area into a large multifunctional urban agglomeration. We employ a specific stated preference method (namely, a willingness-to-pay method) to gauge the project's net socio-economic benefits for the current firms in the area concerned, paying special attention to the benefits associated with multifunctionality. 相似文献

This essay will consider the representation of the maternal in some contemporary Northern Irish fiction written by men. It will examine, using feminist theories of embodiment and subjectivity, the power of the maternal image in Irish literary and critical discourse. The work of Julia Kristeva, Elizabeth Grosz and Mikhail Bakhtin will be employed in this argument. The pregnant body has the power to radically unsettle order, and this essay will explore the way in which men write their fears of this all-consuming imago. Northern Irish men write out their fears of all-consuming national ideology through infanticide and grotesque mother figures and this essay will trace how this figure is complicated through political ideology in Northern Ireland. The texts under consideration will be Ripley Bogle and Eureka Street by Robert McLiam Wilson and Resurrection Man and The Last of Deeds by Eoin McNamee, as well as a glance towards the work of Glenn Patterson as a possible alternative to the hegemonic view of the grotesque or abjected maternal. 相似文献

A collection of 1825 vertebrae belonging to 105 individuals from several Argaric Culture sites (Bronze Age, SE of Spain) were studied. Several pathologies that could provide information about activity patterns were analysed, including spondylolysis, compression fractures and Schmorl's nodes. Spondylolysis appears exclusively in men. Compression fractures seem to be more related to age (osteoporosis) and are more frequent in women, but without statistical significance. Schmorl's nodes affect a large number of the individuals studied, with a slight predominance in men; there are no differences by age. The results obtained were compared with the available archaeological and anthropological information, which shows a clear division of activities by sex in the Argaric population. The validity of studying these pathologies as activity patterns is discussed. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Stable nitrogen isotopes have been used to reconstruct infant feeding practices as nursing infants have elevated δ15N ratios compared with their mothers. However, infancy is also a time of rapid growth, which may alter nitrogen isotope diet‐to‐tissue spacing. Several studies have documented a decrease in δ15N during growth in tissues with relatively fast accretion rates. This study investigates the effect that the growth of long bones, via collagen accretion, has on δ15N ratios. Long bones from individuals aged seven to nineteen years were obtained from a protohistoric ossuary in Ontario, Canada. Analysis of juveniles and adolescents permitted the examination of growth in a group who were not also nursing. It is concluded that a nitrogen isotope growth effect is not detectable in bone collagen from juveniles and adolescents, because: (1) δ15N ratios are not significantly different among the epiphyses, metaphyses and diaphysis of a growing long bone; (2) δ15N ratios are not significantly different between faster‐growing versus slower‐growing metaphyses; and (3) δ15N ratios are not significantly different between bones (or areas of a bone) that are still undergoing growth, versus bones that have ceased growing. The relatively slow speed of collagen accretion may explain why a growth effect is not manifested. Ultimately this research lends support to the use of nitrogen isotopes from bone collagen for infant feeding reconstructions. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
