Seismic Performance to Emergency Centers,Communication and Hospital Facilities Subjected to Nepal Earthquakes, 2015

Emergency centers, communication systems, and hospitals are essential infrastructures for emergency rescue and subsequent reconstruction activities. An investigation into the Nepal 2015 earthquake sequences found that the visited government offices were functioning normally 40 days after the main shock; that the local media failed to coordinate with the entire society at the beginning, but mobile phone-based communication recovered quickly; and that the hospitals in high-intensity areas were badly damaged as a result of improper design and adverse site configuration. Recommendations are proposed to enhance the aseismic capacity of structural and non-structural components using earthquake early warning and base isolation.     

Market mechanisms and migrant settlement intentions in urban China

This study examines the settlement intentions of migrants based on original survey data collected from four large Chinese cities. Despite the long-lasting institutional effects of the hukou (household registration) system, market mechanisms are becoming increasingly important in affecting migrant settlement intentions. Although rural hukou holders are more likely to return to their places of origin, migrants who have received higher education, who are self-employed or who own homes are more willing to permanently settle in cities. The influences of market mechanisms are also reflected in recent policy reforms related to education, housing and the hukou system.     

The bronze artifacts from the Yejiashan site and the political presence of the Zhou dynasty in the middle Yangtze Plain: an application of lead isotope analysis

Lead isotope ratios of 15 Chinese bronze artifacts from the Yejiashan site (Suizhou City, Hubei Province) were analyzed and compared with copper ores across China. This study attempts to provide a new perspective to discuss the role that Zeng State played among all the vassal states in the early Zhou dynasty (ca. 1046–977 BC). The political presence of the Zhou dynasty in the middle Yangtze Plain is another main content of this paper. The lead isotopic characteristics of Chinese bronze artifacts between different historical periods are also in the scope of the study. By comparison, the lead isotopic ratios of the tested bronzes and copper deposits in the north Jiangxi Province show numerous overlaps. It indicates that the tested bronzes might have a single ore source, and this source was in the south of the Zhou dynasty. Combined with history and archaeological records, it is highly likely that the middle Yangtze Plain might be a part of the Zhou dynasty since the very beginning. Moreover, Zeng State might have a great influence in the ancient middle Yangtze Plain, and the nobles of Zeng State might even have authority to supervise certain area extending to Jiujiang. As lead isotopes of the bronzes appear to show a clear relation to chronology, the change of lead isotope patterns across times may further serve to distinguish the bronzes of the Western Zhou dynasty from the late Shang ones.     

A Study on Black‐Body Celadon Excavated in The Altar Guan and Literature Ge (Longquan Ge) Kilns by EDXRF

Samples of celadon were collected from the Altar Guan Kiln in Hangzhou, and from the Xiaomeizhen and Xikou Kilns, two subordinate kilns of the Longquan Kiln producing black‐body celadon called Literature Ge. Both the elemental contents in the sample bodies and the glaze were measured. The results reveal that the sample bodies contain fingerprint information for provenance, while this was lost in the glaze during the production process. The TiO₂, MnO and Rb₂O contained in the bodies are fingerprints to distinguish between celadons from the Xiaomeizhen and Xikou Kilns. In the Altar Guan Kiln, some low‐TiO₂ samples were found and their body colour is much lighter than some others, but they do not differ with regard to iron content. This indicates that both titanium and iron are indispensable for the blackness of the bodies: they may react to form some black minerals during the firing process. Ultimately, samples from the Literature Ge and Altar Guan Kilns differ in their body constituents. Principal component analysis reveals that the samples can be divided into two groups, corresponding to the two different areas.     

Lead Isotope Analyses Revealed the Key Role of Chang'an in the Mirror Production and Distribution Network During the Han Dynasty

Chang'an (now Xi'an) was the capital of the Western Han Dynasty and the starting point of the Silk Road. In the light of the importance of Chang'an as the centre of politics, economy and cultural interaction, the overarching question proposed in this paper is focused on its role in the mirror production and distribution network during Han period. On the basis of chemical and lead isotopic analyses of 34 Han mirrors, this paper discusses the potential existence of a mirror production centre in Chang'an. Meanwhile, a comparative study with mirrors uncovered from the south‐western frontier and from Central Asian and North‐East Asian countries offers new insight into these related issues.     

New fossil damsel–dragonfly clarifies the phylogenetic position of the small Jurassic family Juraheterophlebiidae (Odonata: Epiproctophora)

HUANG D. & NEL A., June 2017. New fossil damsel -dragonfly clarifies the phylogenetic position of the small Jurassic family Juraheterophlebiidae (Odonata: Epiproctophora). Alcheringa, 41, 536–542.

A nearly complete specimen of Juraheterophlebia cancellosa sp. nov., the third species of the family Juraheterophlebiidae, is described from the Middle–Late Jurassic of China and shows the exact structure of its forewing discoidal space. As a consequence, this family is restored, separated from Erichschmidtiidae, and its diagnosis amended. It is transferred from Heterophlebioptera to Stenophlebioptera, the first clade being now only known from the Early Jurassic. Erichschmidtiidae includes the sole species Erichschmidtia nigrimontana, and this family is now considered of uncertain systematic position.

A continuing agenda for gender: the role of the IGU Commission on gender and geography

In examining the development of the International Geographical Union’s (IGU) Commission on Gender and Geography over the last three decades, we first highlight the advances made to establish visibility for gender studies within the IGU and create structures for more inclusive feminist geographies across national, disciplinary and other borders. Given that many of the early and most widely-known advances were largely within Anglophone contexts, we then discuss the ongoing challenges and possibilities for advancement faced by feminist geographers who teach, research, and write on gender in other locations. While some of these challenges (such as a continued lack of recognition for gender studies, paternalistic hierarchies, and specific government regimes) are country-specific, others are related to broader issues of neoliberalism and corporatization, and inequities in academic publishing. Clearly, continued efforts are needed to strengthen the agenda for gender to promote more inclusive histories, practices and processes of gender/feminist geography in research, teaching and application in the international arena.

至正十一年铭青花云龙瓶考

至正十一年铭青花云龙瓶是一对专门订制的庙宇供器,它的产生与宋元时期南方的五显神信仰有关。其最初供奉地是距景德镇约68公里的婺源县灵顺庙,供奉对象是五显神的从神"胡靖一"。供奉者张文进是距离景德镇约110公里的信奉五显神的商人。承造这套青花瓷瓶的是生产元青花瓷器的中心窑场,其地点可能在今景德镇市区内。
