This paper reports the results of a series of material performance tests undertaken to compare Chinese and Australian 500 MPa reinforcing steel. After providing some background to modern high strength reinforcing steel, this paper compares the chemical and mechanical requirements of the reinforcing steels in Chinese codes with those in Australian standards. The results of tensile strength and ductility tests are reported. From the requirements of the standards and the analysis of the test data, several conclusions are drawn. Small differences in the chemical composition cause some differences in mechanical properties. Because of the higher percentage of carbon, the tensile strength of Chinese reinforcing steel is generally higher than that of Australia's normal ductility (N) reinforcing steel. The ductility of Australia's normal ductility reinforcing steels is somewhat less than that of Chinese reinforcing steels, due to the higher percentages of the chemicals phosphorous and sulphur. However, because of the lower value of Ceq and carbon content, the weldability of Australian steel is higher than Chinese steel. By adding the trace elements V, Nb and Ti into the steels, the seismic ability of Chinese steels has been improved. Both Chinese and Australian reinforcing steels tested had adequate yield stress levels. In each country the test results indicated that the tested steel achieved the requirements of the applicable standard. [ABSTRACT FROM AUTHOR]

A rare species, Doryphoribius zyxiglobus, was found in mosses in New Zealand. So far, it has been cited only three times; from Australia, New Zealand and central China. The original description is very brief and is insufficient by today's taxonomic standards and seems not to be based on the holotype. A photograph of the slide mounted holotype (obtained from The Museum of New Zealand) showed it to be so poorly preserved and oriented that it was deemed probable that little would be gained by its further examination. Consequently, the redescription was based on a few limited measurements from the photograph of the holotype with a complete set of measurements of a paratype and supported by morphometric analysis of a set of topotypes—all borrowed from The Museum of New Zealand. A comparison between sets of specimens from three countries (New Zealand, Australia and China) and a single specimen from South Africa permitted an evaluation of the geographic variation of this species. This paper thus redescribes D. zyxiglobus, reports on populations from widely separated locales and extends its geographical range. [ABSTRACT FROM AUTHOR]

Stem cell science is an emerging global industry in which nation states compete fiercely for economic advantage. Currently, the USA dominates this international competition but critics have argued that it lacks an innovation strategy to maintain its position. Strong international competition and internal policy problems may pose significant challenges to the future of US stem cell science. At the same time, the governments of the UK, China, India, Australia and Singapore are developing strategies to enhance their competitive edge within the global stem cell economy. How should the US government respond to these developments? Is a federal strategy necessary to protect the advantages of the US stem cell industries or can it be assumed that the present innovation infrastructure is sufficiently flexible and dynamic to cope with the global challenge? In this paper we address these questions through an examination of the US stem cell innovation system from the perspectives of science, society and the market. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic shows variable dynamics in WHO Regions, with lowest disease burden in the Western-Pacific Region. While China has been able to rapidly eliminate transmission of SARS-CoV-2, Germany – as well as most of Europe and the Americas – is struggling with high numbers of cases and deaths. Objective: We analyse COVID-19 epidemiology and control strategies in China and in Germany, two countries which have chosen profoundly different approaches to deal with the epidemic. Methods: In this narrative review, we searched the literature from 1 December 2019, to 4 December 2020. Results: China and several neighbours (e.g. Australia, Japan, South Korea, New Zealand, Thailand) have achieved COVID-19 elimination or sustained low case numbers. This can be attributed to: (1) experience with previous coronavirus outbreaks; (2) classification of SARS-CoV-2 in the highest risk category and consequent early employment of aggressive control measures; (3) mandatory isolation of cases and contacts in institutions; (4) broad employment of modern contact tracking technology; (5) travel restrictions to prevent SARS-CoV-2 re-importation; (6) cohesive communities with varying levels of social control. Conclusions: Early implementation of intense and sustained control measures is key to achieving a near normal social and economic life. [ABSTRACT FROM AUTHOR]

The experiences of an architectural, an engineering, and a construction organization, when internationalizing to China, are compared to extant theories of internationalization to develop an enhanced explanation of these organizations’ internationalization. The research examines the explanatory power of both the Uppsala internationalization model and network theory for internationalization. The research determined that, whilst these organizations utilized an incremental internationalization process, the stages differed from those identified in the Uppsala model. Part of this difference reflects the fact that the participants are service organizations and the Uppsala model is more relevant to manufacturing organizations. Network theory was also found to predict some of the participant behaviors; however, it did not correctly predict the reasons for forming partnerships, which was to gain knowledge rather than develop networks. The stages of the internationalization into China identified were: (1) experiencing a motivation to internationalize; (2) adopting one of a variety of entry modes; (3) experiencing a motivation to increase internationalization to the level of a wholly-owned foreign entity; (4) establishment of a wholly-owned foreign entity (WOFE), either by acquisition or development; and (5) further horizontal expansion (such as movement to new locations). A range of different motivations for both stages one and three were identified. [ABSTRACT FROM AUTHOR]
