Usually, Ps 57 is seen as formcritically mixed, but the exact interrelation between personal lament und thanksgiving song has not yet been established. Philological observations (especially, verbal forms and sentence structures) and formcritical deliberations make it clear, that 2-6 is a lament and 7(!)-12 a thanksgiving song. Therefore, 7 is interpreted as a retrospect of the trouble (7ab) and as a report of the deliverance (7cd). The tricola 8abc and 9abc have the same structure: a citation of a song (ab) followed by a speech-action (c). The structure of the psalm with its two stanzas and the closing refrains support this interpretation. By means of different poetic elements (refrain, the word "heaven" etc.) the two genres are interrelated, resulting in an organic whole.  相似文献

Today, science and scientists as experts no longer hold sway as unquestioned authoritative sources of objective information in many policy debates. This has led to growing frustration on the part of government officials and scientists over their inability to have science exert as meaningful a role as they think appropriate in the consideration and selection of policy alternatives. Given this development, what can be done to restore or otherwise ensure that the appropriate science and scientists are integrated into the policy process so that they matter to policy outcomes? There is general agreement that traditional top‐down, one‐way (from scientists to others), linear models for conceptualizing the role of science and scientists in the policy process are not capable of capturing the changed political, social, and “scientific” realities of the contemporary policymaking context. Many have gravitated to the concept of civic science/scientists as a new and improved model. Yet, despite clear progress in reconceptualizing the role of science in the policy process, there are gaps in the literature when it comes to actual applications of civic science. As McNie correctly notes: “it is essential that we develop a more robust understanding of experience and practical experiments regarding how relationships [and institutions] are constructed and managed across the science‐society boundary” (p. 29). This research develops lessons for civic science in the policy process by exploring an innovative collaborative governance effort by the National Oceanic and Atmospheric Administration Fisheries and the Shared Strategy for Salmon Recovery in Puget Sound (Washington). The integration of science into the salmon recovery process in this case relied on a series of actions that the Technical Recovery Team (TRT) took to bridge the traditionally separate science and policy spheres in order to increase the certainty of science impact, specific steps taken to establish and maintain the TRTs role as an authoritative, credible source of science, and the embrace of a results‐oriented, adaptive learning approach.  相似文献

Expectations for survival of vertebrate remains have been well developed and intensely studied in the zooarchaeological taphonomic literature. Taphonomic studies of shellfish remains focus on marine species and on variables relevant to remains from paleontological contexts (e.g., fossil marine beds). In this paper we develop a conceptual framework from which to derive expectations concerning the preservation of freshwater mussel remains focusing on two parameters, shell microstructure and shell shape. Shell size does not influence survivorship. Our model is validated through application to late Holocene zooarchaeological mussel assemblages from north Texas. Taphonomically robust species are important regarding zooarchaeological and biogeographic interpretations based on mussel paleofaunas, and fragile species are important indicators of whether or not an assemblage is well preserved.  相似文献

Extraction of protein residues from archaeological matrices, such as pottery clay, lithics, and grinding stones, has proven to be methodologically challenging. Protein residue analysis is fraught with technical challenges in analytical chemistry. In cooking pottery, protein residues are thought to bind to clay surfaces in vessel walls through a variety of primarily non-covalent interactions. Removal of protein residues requires the disruption of these interactions, and a diverse set of tools has been proposed and applied. Here, we test extraction procedures through varying combinations of physical parameters and solvents to derive an optimal approach yielding efficiencies of recovery from experimental pottery above 60%. The utility of our extraction approach was further validated through liquid chromatography?Cmass spectrometry analysis of experimental residues. We have identified several hurdles to developing a successful study of protein residues from pottery, each of which is surmountable with additional method development in the realm of archaeological chemistry.  相似文献

Heritage sites regarded as important are safely managed by the state, voluntary or private sectors but the majority of sites, despite statutory protection, remain unrecognised and without a role in their host communities. New schemes such as the Local Heritage Initiative in the UK aim to encourage communities to recognise their heritage assets and in managing them effectively to contribute to their preservation. With reference to the case of Nether Poppleton near York (UK), the present study explores the factors and conditions for effective community management displayed in one locality by groups who are successfully conserving and managing a diverse set of local heritage sites. Interviews and joint tasks enabled an analysis of the complex range of factors and conditions that can lead to a successful community-based initiative. Future research will determine the extent to which these factors, if applied to other sites, might produce the same results. The importance of this agenda is underscored by the increasing reliance on community-based heritage management in the UK and elsewhere.  相似文献
