Possible rheumatoid arthritis found in the human skeleton collected from the tomb of Joseon Dynasty,Korea, dating back to the 1700s AD

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 Right to the City and Critical Reflections on China's Property Rights Activism

Wholesale clearance and eviction that typify China's urban development have often resulted in discontents among urban residents, giving rise to what critics refer to as property rights activism. This paper is an attempt to critically revisit the existing debates on the property rights activism in China. The paper refers to the perspective of the “right to the city” to examine whose rights count in China's urban development contexts and proposes a cross‐class alliance that engages both migrants and local citizens. The alliance itself will have substantial political implications, overcoming the limited level of rights awareness that mainly rests on distributional justice in China. The discussions are supported by an analysis of empirical data from the author's field research in Guangzhou, which examines how local and non‐local (migrant) residents view nail‐households resisting demolition and forced eviction.     

Characteristics of ESR signals and TLCLs of quartz included in various source rocks and sediments in Japan: A clue to sediment provenance

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.     

Response of cathodoluminescence of alkali feldspar to He+ ion implantation and electron irradiation

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.     

The Saga of the ‘Second industrial divide’ and the history of the ‘third Italy’: Evidence from export data

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.     

Evaluation of community planning and life of senior cohousing projects in northern European countries1

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.     

SUBJECTIVE INDICATORS AND DISTRIBUTIONAL RESEARCH ON PUBLIC SERVICES

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.     

Ectopic paragonimiasis from 400-year-old female mummy of Korea

Of the parasite eggs discovered in ancient samples from Korean archaeological sites, Paragonimus spp. are of particular importance in that they are regarded as one of the most insidious trematode infection sources. Although their infection prevalence decreased rapidly in the early 20th century, archaeoparasitological studies on the species are still required, as historical knowledge of paragonimiasis remains far from comprehensive. Fortunately, we recently were given a chance to examine a medieval Korean mummy in a good state of preservation. Using morphological techniques, we discovered evidence of ectopic paragonimiasis in the sample from the 17th-century female. When the ITS 2 gene was extracted, amplified and sequenced from Paragonimus eggs, it showed 100% homology to the sequences of modern Paragonimus westermani reported from Korea and Japan, forming a cluster distinct from South Asian P. westermani. Our report is the first-ever analysis of ancient Paragonimus DNA from any archaeological field in the world. The ectopic paragonimiasis diagnosis made in this study, especially involving the liver sample, also is the first of its kind in archaeoparasitology.     

Is it time to start worrying more about growing regional inequalities in Canada?

Much has been written recently about the rise of within-country inequality and growing imbalances of regional fortunes in the United States and the European Union. In this paper, we apply a novel geo-visualization technique that combines local indicators of spatial association with directional statistics to a unique dataset in order to explore the spatial dimensions of regional income inequalities in Canada from 1981 to 2016. After describing a pattern of growing spatial divergence among regions, we briefly discuss the need for the federal government to explore new types of place-sensitive development policies.
