This paper expands the Narrative Policy Framework (NPF) by employing an exploratory case study approach to examine the construction of narratives temporally. A large-N Twitter dataset concerning the Bears Ears and Grand Staircase-Escalante monuments controversy is utilized to examine the question: how does the use of narrative strategies change over time? Through the application of change-point analysis, we determine time points of significant shifts towards use of the devil-angel shift, scope of the conflict, and causal mechanism strategies. Overall, we find that organizations do not vary their use of narrative strategies over the course of a policy conflict but instead demonstrate discrete changes in response to certain policy events. Based on our findings, we conclude with suggestions for refining and expanding NPF hypotheses. Specifically, we recommend a more contextual analysis of shifts in narrative strategy use in response to specific events over time. 相似文献

A total of 1164 temporal bones from various cemetery sites in England were examined using a fibre optic endoscope. Eight bones were found to have evidence of otosclerosis in which proliferative new bone fixes the footplate of the stapes into the oval window, causing deafness. A prevalence of 0.9 per cent in this study is comparable with the incidence found in modern white populations and with that found in a study of 2760 Lithuanian temporal bones of various periods. 相似文献

We report the results of testing the diameter of the internal opening of the acoustic canal in the petrous part of the temporal bone for sex determination of skeletal remains. The method involves measuring the diameter using a suite of ordinary drills. The method is very simple and has the great advantage of utilising one of the sturdiest bone elements of the human skeleton. The method may be especially useful for the analyses of very fragmented skeletal remains or cremated bones, where the petrous bone may still be readily recognisable. The method was tested using a forensic sample of 113 left petrous bones with known sex. Intra‐ and inter‐observer testing was also performed. We found a statistically significant difference in diameter between males and females (means: males: 3.7 mm; females: 3.4 mm; P < 0.009). However, the low predictive value (70%) for correct sexing using two sectioning points ( < 3.0 mm = female; >3.5 mm = male) was disappointing. No additional accuracy was gained by employing both left and right petrous bones (a bilateral sample of 60 petrous bones was also tested), although left and right side diameter is highly correlated (R = 0.778; P = 0.0001).

思维方式是社会实践的产物,社会主体从事不同的实践产生不同的思维方式。骗子作为一种社会角色、一种职业,在社会活动中经常地反映出其定型化的思维方式。其中,最常见的骗子思维方式,主要有以下几种:模糊性思维方式,动态性思维方式,系统性思维方式,揭示骗子思维方式的几种主要形态,为进一步研究中国传统社会中的骗子现象,提供了更加宽广的空间。 相似文献

This study investigates changes in past human and animal relationships by focusing on pig (Sus scrofa) remains excavated from archaeological sites in southern Kanto, Japan. Pigs and humans have had a close relationship since prehistoric times and the process of change in this relationship, including possible domestication, is one of the major issues in Japanese zooarchaeology. This study attempts to gain a better understanding of the nature of past interaction between humans and pigs by investigating their relative importance compared with other vertebrate remains, kill‐off patterns, and changes in their size and shape at these sites. The materials used for this study date from the Earliest to Final Jomon (ca. 10,000–2500 BP), Yayoi (ca. 2500–1700 BP) and Kofun (ca. 1700–1300 BP) periods. The relative proportions of pigs were calculated to show the overall trend of pig exploitation in each site. Age at death was obtained based on the state of tooth eruption. Bucco‐lingual crown measurements were taken on the third and fourth premolars and on each cusp of the first and second molars of the mandible, and the logarithmic ratio technique was then applied to these data. The age structure of Sus varies between different sites in the Jomon Period, and significant changes were observed in the Yayoi and Kofun Periods. A decrease in the relative proportion of pigs in the faunal assemblages was observed from Jomon to Kofun. Three major differences were observed in the size of pigs. The overall size of pigs significantly increased from Early to Middle Jomon, whilst a decrease in size occurred in the Yayoi Period. Finally, overall size increased significantly during the Kofun Period. Together with the archaeological evidence—such as the ritual burial of pigs accompanying human burial—we suggest that the interaction between pigs and humans became gradually stronger at some sites during the Late Jomon Period, and the relationship intensified in the Yayoi Period.
