We report a possible rheumatoid arthritis (RA) case found in a Korean Joseon Dynasty (1392–1910) tomb encapsulated by a lime‐soil mixture barrier (LSMB). The tomb is thought to have been constructed during the 1700s AD (1760 AD by carbon dating). In our anthropological examination, joint destruction, erosion or fusion (signs of polyarthritis) were identified mainly in the peripheral skeleton. Especially in both sides of the wrist bones, severe destruction/joint fusion possibly caused by polyarthritis was observed. A similar polyarthritis pattern also was seen in the right foot bones, even though we failed to confirm this symmetry due to the missing left foot bones. Despite these findings, signs suggestive of polyarthritis are very rarely seen in axial bones, even though bony fusions are found in the atlanto‐occipital joint or thoracic vertebrae (TV) 9–10. By the osteological signs observed in this case, the individual, a female, might have been suffering from a very late stage of RA and died in her 40s, even though other forms of chronic arthritis could not be ruled out completely. Though the current case could not provide evidence to decisively settle the debates on the antiquity of RA, our report could be a stepping stone for forthcoming studies on RA cases found in East Asian countries.

The idea of the Third Italy has achieved an iconic status in geography. It has come to represent one of the main geographical manifestations of the so‐called second industrial divide between Fordist mass production and flexible specialisation. Yet the idea has received limited critical attention since acquiring its elevated status. It deserves to do so, because it involves confusing a localised model of economic development with the economic character of a larger geographic region. Examining province level export data for the years 1985, 1991, 1995 and 1999 for both total exports and two key sectors using exploratory spatial data analysis, provincial rankings and LISAs (local indicators of spatial association) suggests that the export‐based homogeneity and dynamism of the Third Italy can be exaggerated. Italy's urban hierarchy, particularly the centrality of Milan, continues to play a significant role in the Italian economy. Common use of the term ‘Third Italy’ confuses an economic process with a specific geographical configuration.  相似文献

ABSTRACT

This study examines Australian domestic film performance under two distinct policy regimes with respect to direct investment strategy. In particular, we contrast film performance under two public funding agencies with noted differences in (i) the number of films financed annually, (ii) the average (and maximum) funding per film, and (iii) the involvement of an expert review panel in funding decisions. In addition to box office returns, we consider performance benchmarks related to major film festival screenings, nominations and awards; critical acclaim based on IMDb user and critic reviews; and whether or not the film received a release in the major UK and/or US markets. Finally, we exploit a subset of our data where a ‘two-door’ policy was used for investment decisions that allows us to reflect on our more general results.  相似文献

This article explores the role of three conservative newspapers in South Korea as storytellers that create and maintain the collective memory of Korean conservatives through textual analysis of news stories on one particular recent event, the 2008 Korean Candlelight Vigil. Several protests since the 1980s in which the democratic-progressives were a leading force have been used as a source of historical analogies that have helped conservative journalists to interpret contemporary events and issues, including the 2008 vigil. These past protests were framed as anti-American, pro-North Korean leftist actions in the news stories. Some aspects of these past events were omitted – for example, former democratic-progressive activists’ contribution to the democratisation process – while other aspects were emphasised, notably the violent nature of the earlier generation of activists. In addition, conservative journalists constructed a revisionist version of one particular past protest, the 2002 Korean Candlelight Vigil, and used it to serve present political purposes, conflating the rhetoric and language of the earlier protests into their reporting of the current protest. These discourse strategies helped to incorporate the current protest into a larger discourse of “the threat posed by the leftists”, which is embedded in the collective memory of Korean conservatives.  相似文献

The variation of electron spin resonance (ESR) signal intensities and thermoluminescence colour images (TLCIs) of quartz was investigated in the present study for various rocks and sediments in Japan, to discuss the possibilities of identifying the sediment provenance. The ESR signal intensity of the E1’ centre in the same grain size in granitic quartz varies from sample to sample, except for that in Quaternary samples of volcanic sediment, which is very low, close to the noise level. It was found that the diagram, ESR intensities of Al versus Ti-Li centre signal intensities, distinguish volcanic from the same grain size in granitic quartz as well as distinguish individual tephra from another. The TLCIs from volcanic quartz and some granitic quartz samples is almost red and that from the rest of granitic and metamudstone quartz is blue as results of TLCIs although the emission intensities are different. Our results suggest that examining the multiple-centre signal intensities of ESR and the TLCIs are effective to identify the source of quartz and to estimate the sediment provenance.  相似文献

Cathodoluminescence (CL) of minerals such as quartz and zircon has been extensively studied to be used as an indicator for geodosimetry and geochronometry. There are, however, very few investigations on CL of other rock-forming minerals such as feldspars, regardless of their great scientific interest. This study has sought to clarify the effect of He+ ion implantation and electron irradiation on luminescent emissions by acquiring CL spectra from various types of feldspars including anorthoclase, amazonite and adularia. CL intensities of UV and blue emissions, assigned to Pb2+ and Ti4+ impurity centers respectively, decrease with an increase in radiation dose of He+ ion implantation and electron irradiation time. This may be due to decrease in the luminescence efficiencies by a change of the activation energy or a conversion of the emission center to a non-luminescent center due to an alteration of the energy state. Also, CL spectroscopy of the alkali feldspar revealed an in-crease in the blue and yellow emission intensity assigned to Al-O?-Al/Ti defect and radiation-induced defect centers with the radiation dose and the electron irradiation time. Taken together these results indicate that CL signal should be used for estimation of the α and β radiation doses from natural radionuclides that alkali feldspars have experienced.  相似文献

Quartz is one of the minerals useful for electron spin resonance (ESR) dating. The E1′ center is one of well-known paramagnetic defects in crystalline quartz. This center has a unique feature; its intensity increases on heating. An electronic process to explain this increase was found to be controlled not only by the number of oxygen vacancies, which are the precursors, but also by the number of Al hole centers, which depend on the previous radiation dose and on the Al concentration.  相似文献

Cohousing schemes were evolved as alternative housing to reduce housework for working women, and to reduce loneliness of elderly people by promoting active mutual relationship with community residents in northern European countries. This article discusses how residents manage their life in senior cohousing projects in Sweden and Denmark. The purpose of this study is to investigate residents' life satisfaction connected with demographic characteristics of residents, physical environment and common activities in the senior cohousing communities, so that it could offer usable information for the establishment of new senior cohousing projects in other countries, as well as an empirical evaluation of the existing projects in Scandinavian countries themselves. Important variables influential to residents' life satisfaction are also discussed in order to improve senior citizens' quality of life. The methods used for the study are literature review, interviews, field trips and questionnaire. Nine hundred and thirty‐five postal questionnares were sent to 28 senior cohousing communities throughout Denmark and Sweden. Of those 536 replies were collected and analysed by SPSS program using frequency, mean and Chi‐square test. As a result, it was found out that most of the respondents are healthy, 70‐year‐olds, and satisfied with their current living in the community. The majority of them also would like to strongly recommend others to move to senior cohousing schemes to improve quality of life in their later years. Residents' intensive concern about building location and design is a noteworthy reminder for designers and architects as well as for professionals and decision‐makers who work in the elderly welfare sector.  相似文献

Despite high prevalence of Trichuris trichiura infection, PCR-based analysis on T. trichiura from archaeological samples has not been established so far. In the present study, we sought to perform PCR-based amplification of T. trichiura aDNA using the sediments from medieval tomb of Korea. The presence of Trichuris eggs were first detected by microscopic observation; then confirmed by PCR-based aDNA analysis. Obtained sequence showed 100% homology to that of the small subunit ribosomal RNA (SSUrRNA) gene of T. trichiura but distinct from that of other Trichuris species. PCR-based aDNA analysis in this study can serve as effective method to confirm the presence of T. trichiura eggs in the soils or coprolites collected from archaeological sites.  相似文献

This article uses data from 15 U.S. cities to explore the ways in which the use of subjective measures of service satisfaction can redirect distributional research from the question of who gets how much to the more policy-relevant question of who gets how much of what is needed. It suggests a useful approach to the use of subjective indicators to provide more valid and meaningful measures in distributional research.  相似文献
