The stranger that is welcomed: female foreign students from Asia,the English language industry,and the ambivalence of ‘Asia rising’ in British Columbia,Canada

In 2002, attacks on six Asian women and girls temporarily living in the Greater Vancouver Area, Canada to study the English language garnered significant attention. Beginning with the attempted murder of Korean national Ji-Won Park, and ending with the murder of Chinese national Wei Amanda Zhao, the attacks on Asian females sparked a national debate about the vulnerability of foreign language students of Asian origin, and Canada's responsibility to protect them. Drawing on mainstream media accounts, this article examines how the intersection of race, gender and class produced the event as a story of national interest and as one of the province of British Columbia's most significant events of 2002. Highlighting the shifting positioning of Asian difference in contemporary western space, this research contributes to recent theorizing on how Asianness in the west no longer primarily signifies backward, underdeveloped nations and peoples best kept in their place, in another space. I argue that western discourse on Asian difference is defined by ambivalence. While the economics of the English language industry and the geopolitics of ‘Asia rising’ led to a heightened interest in these acts of violence, gender and processes of feminization simultaneously reduced concern over what is arguably an anxiety producing event in the west: Asia's economic ascendancy and the west's positioning in the ‘Asia Pacific century’.     

DISENTANGLING AGGLOMERATION ECONOMIES: AGENTS,SOURCES, AND SPATIAL DEPENDENCE*

ABSTRACT This paper expands the literature on agglomeration economies in three ways. It disentangles amenity and productivity effects of agglomeration; it decomposes aggregate scale effects into agglomeration factors of interest to policy makers; and it estimates own effects and spillovers to neighbors. It proposes a spatial simultaneous equations model in a spatial equilibrium framework with three agents—workers, consumers, and producers of traded‐goods and housing. Results for Ohio counties estimate economies resulting from population size, agglomeration causes, and public service quality and cost on each of the three agents in own and neighboring counties.     

Iron technology of the ancient megalithic communities in the Vidarbha region of India

The megalithic period in India is notable for the emergence and development of iron metallurgy and the appearance of new burials known as megaliths. A number of iron objects from megalithic sites in the Vidarbha region of India, dating to the first half of the 1st millennium BC, have been examined for their microstructures and carbon distributions. The artifact assemblage consists mainly of edged or pointed tools and weapons, along with some domestic implements. Results show that the technology applied in their manufacture is characterized by the use of low carbon iron of bloomery origin and the application of surface carburization as the primary means of steelmaking. The functional parts of the objects examined were made mostly of steel with their mechanical properties finely adjusted through a combination of quenching and tempering. Of particular importance are certain fan-shaped plates which we believe were produced and circulated as intermediaries to meet a wide range of consumer needs. It appears that the Vidarbha megalithic communities shared a fully developed and well-standardized iron technology of substantial flexibility. While exceptions to this general trend were found in some unfinished or used objects, these do not suggest the presence of an inferior technological status. This paper raises questions as to the origin of such a developed technology, and will discuss the probable spreading of several key technical ideas which bear striking similarities to those noted in the early iron traditions of Korea.     

TIME SERIES AND TURNING POINT FORECASTS: A COMPARISON OF ASSOCIATIVE MEMORIES AND BAYESIAN ECONOMETRIC TECHNIQUES APPLIED TO LESAGE'S DATA*

ABSTRACT. Associative memory techniques are drawn from the artificial intelligence literature, and have demonstrated considerable utility for parameter identification in dynamical systems. Previous turning point forecasts constructed by LeSage are compared to forecasts generated by associative memories and simple autoregressive models. Both the associative memories and the autoregressions perform as well or better than the more complicated econometric procedures described by LeSage, with the exception of West and Harrison's (1989) dynamic linear model specification. Extensions are suggested.     

A technological transition in Mongolia evident in microstructure,chemical composition and radiocarbon age of cast iron artifacts

Metallurgical examination of cast iron objects from the Khitan period (AD 10th–12th) in Mongolia shows that they might be classified into two groups. The first is based on Fe–C alloys of near eutectic composition and the second is based on Fe–C–Si alloys with reduced carbon content and numerous sulfide inclusions. By contrast, all the objects from the succeeding Mongolian empire period (AD 12th–15th) belong to the second group, indicating that a technological transition had occurred during the Khitan period. Accelerator mass spectrometry (AMS) on carbon samples extracted from artifacts in both groups and measurement of alloy compositions suggest that the use of mineral coal in smelting was a major factor for this transition.     

Diffuse idiopathic skeletal hyperostosis cases found in Joseon Dynasty Human Sample Collection of Korea

Diffuse idiopathic skeletal hyperostosis (DISH) is a disorder showing hyperostosis of the spinal column and ossification of extraspinal ligaments or tendons. The prevalence of DISH has been found to be higher in historic peoples of the upper‐ and ruling classes, and in fact was closely correlative with nutritional and high‐caloric diets. DISH is also known to be a function of genetic factors; as such, there have been very few cases of DISH found among the specimens of Asian skeletal collections. In our osteoarchaeological study on the Joseon Dynasty Human Sample Collection (JDHSC), we found four DISH instances among the 96 cases (4.17%) we examined. This prevalence is not so different from those discovered in already‐published studies on collections in Europe and other regions. However, as already stated, it must be considered that most of the JDHSC individuals we examined were remains of people from the highest social classes of 16th–18th century Joseon society. Therefore, when collections from medieval European monastic sites, the appropriate control from well‐fed populations, were used for comparison, the prevalence of DISH was found to be far lower among the JDHSC. Reports on DISH from examinations of collections in Asian countries have been spotty, leaving gaps in the social‐strata spectrum. Further researches into the prevalence of DISH among the different social strata of ancient or medieval Asian peoples are still required. Copyright © 2010 John Wiley & Sons, Ltd.     

Technology,chronology and the role of crucible steel as inferred from iron objects of the ancient site at Junnar,India

Ordinary iron objects from an ancient habitation site at Junnar in India, dating to the 2nd BC to AD 2nd century, were examined for their microstructure, chemical composition and age. The objects were mostly made of high carbon steel with a homogeneous microstructure consisting of fine spherical particles of carbide in the ferrite background, free of non-metallic inclusions. Their carbon concentration ranged from 0.7% to over 1.6% with one exception at 0.2%. Some of them contained trace amounts of silicon, manganese and sulfur while one object retained cavities due to volume contraction during solidification reactions. These features indicate that the objects examined constitute an early example of Indian steel making in crucibles. Evidence was found that basic techniques needed for the success of crucible steel technology were mostly available at Junnar at the time. The radiocarbon measurement on carbon samples extracted from one of the iron objects placed its date between 176 BC and AD 20, in agreement with the radiocarbon dates of three charcoal samples from the same site. The forgoing results support that crucible steel was produced in India at a much earlier date than previously supposed, to serve as a material for specific needs arising in daily life.     

A late Miocene–early Pliocene Mihirung bird (Aves: Dromornithidae) from Victoria,southeast Australia

Park, T. & Fitzgerald, E.M.G. September 2012. A late Miocene–early Pliocene Mihirung bird (Aves: Dromornithidae) from Victoria, southeast Australia. Alcheringa 36, 427–430. ISSN 0311-5518.

An incomplete tarsometatarsus identified as an indeterminate species of Dromornithidae is described from the upper Miocene–lower Pliocene shallow marine Black Rock Sandstone at Beaumaris, Victoria, Australia. This isolated specimen represents one of the few pre-Pleistocene dromornithids with a well-constrained geologic age. Additionally, it is one of the few pre-Quaternary dromornithid fossils recorded from southeast Australia. Comparisons with known dromornithid taxa suggest that the Beaumaris dromornithid is distinct from previously established species. This hitherto unknown species of dromornithid in the late Neogene of southeastern Australia cautions against deriving evolutionary patterns solely on the basis of fossils from northern Australia.
