Qingdao As a Colony: from Apartheid to Civilizational Exchange
Qingdao as a colony: From Apartheid to Civilizational Exchange George Steinmetz Paper prepared for the Johns Hopkins Workshops in Comparative History of Science and Technology, ”Science, Technology and Modernity: Colonial Cities in Asia, 1890-1940,” Baltimore, January 16-17, 2009 Steinmetz, Qingdao/Jiaozhou as a colony Now, dear Justinian. Tell us once, where you will begin. In a place where there are already Christians? or where there are none? Where there are Christians you come too late. The English, Dutch, Portuguese, and Spanish control a good part of the farthest seacoast. Where then? . In China only recently the Tartars mercilessly murdered the Christians and their preachers. Will you go there? Where then, you honest Germans? . Dear Justinian, stop dreaming, lest Satan deceive you in a dream! Admonition to Justinian von Weltz, Protestant missionary in Latin America, from Johann H. Ursinius, Lutheran Superintendent at Regensburg (1664)1 When China was ruled by the Han and Jin dynasties, the Germans were still living as savages in the jungles. In the Chinese Six Dynasties period they only managed to create barbarian tribal states. During the medieval Dark Ages, as war raged for a thousand years, the [German] people could not even read and write. Our China, however, that can look back on a unique five-thousand-year-old culture, is now supposed to take advice [from Germany], contrite and with its head bowed. What a shame! 2 KANG YOUWEI, “Research on Germany’s Political Development” (1906) Germans in Colonial Kiaochow,3 1897–1904 During the 1860s the Germans began discussing the possibility of obtaining a coastal entry point from which they could expand inland into China. -
Changing Jellyfish Populations: Trends in Large Marine Ecosystems
CHANGING JELLYFISH POPULATIONS: TRENDS IN LARGE MARINE ECOSYSTEMS by Lucas Brotz B.Sc., The University of British Columbia, 2000 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate Studies (Oceanography) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2011 © Lucas Brotz, 2011 Abstract Although there are various indications and claims that jellyfish have been increasing at a global scale in recent decades, a rigorous demonstration to this effect has never been presented. As this is mainly due to scarcity of quantitative time series of jellyfish abundance from scientific surveys, an attempt is presented here to complement such data with non- conventional information from other sources. This was accomplished using the analytical framework of fuzzy logic, which allows the combination of information with variable degrees of cardinality, reliability, and temporal and spatial coverage. Data were aggregated and analysed at the scale of Large Marine Ecosystem (LME). Of the 66 LMEs defined thus far, which cover the world’s coastal waters and seas, trends of jellyfish abundance (increasing, decreasing, or stable/variable) were identified (occurring after 1950) for 45, with variable degrees of confidence. Of these 45 LMEs, the overwhelming majority (31 or 69%) showed increasing trends. Recent evidence also suggests that the observed increases in jellyfish populations may be due to the effects of human activities, such as overfishing, global warming, pollution, and coastal development. Changing jellyfish populations were tested for links with anthropogenic impacts at the LME scale, using a variety of indicators and a generalized additive model. Significant correlations were found with several indicators of ecosystem health, as well as marine aquaculture production, suggesting that the observed increases in jellyfish populations are indeed due to human activities and the continued degradation of the marine environment. -

Analysis of Climate Change in the Coastal Zone of Eastern China

Re- sults obtained showed a number of observations: 1) The annual mean temperature of Shandong Peninsula showed a significant increasing trend, with a distinct abrupt change point detected around 1990, during the past 5 decades. The warming of the Peninsula over the last 50 years was due mainly to the significant increase of annual minimum tem- perature. The annual maximum temperature demonstrated a mixed trend of decreasing and increasing, but was statisti- cally insignificant, and no abrupt change was detected; 2) The annual precipitation exhibited a decreasing trend during the past 5 decades, with an abrupt change detected around 1980 at most stations; but there was an earlier transition point at 1966, at a few stations. -
The Effects of Eutrophication on Jellyfish Populations in New Jersey Waterways
The Effects of Eutrophication on Jellyfish Populations in New Jersey Waterways How this issue in the Mississippi River delta can be used to predict the effects of eutrophication in New Jersey’s waterways Tag Words: Jellyfish; Eutrophication; New Jersey; CODAR Authors: William Pirl, Emily Pirl with Julie M. Fagan, Ph.D Summary: (WP) What people are doing on land is having a large effect on the coastal ocean waterways. Human beings are introducing excessive amounts of nutrients into these waterways, which is causing biological dead zones that support little productivity. With fewer fish to compete with and hide from, jellyfish are taking over in these areas. This is very true for the New Jersey coastline, specifically in Barnegat Bay. This area is highly enriched from anthropogenic nitrogen sources and there has been an explosion in jellyfish populations in recent years. By coupling research and monitoring programs that have been established in the Gulf of Mexico with CODAR Hf radar it is our goal to allow New Jersey to monitor, study and track these harmful blooms of jellyfish back to the sources of eutrophication in coastal waterways. Video Link: http://youtu.be/S00bAylLd6s ** Listed on You Tube as “Eutrophication in New Jersey” Jellyfish Populations Explode (WP) Jellyfish populations around the world have skyrocketed in recent years. There have been reported increases in jellyfish blooms from Japan to Portugal and most of the areas in between. There is an extensive list of negative consequences that these large increases of jellyfish populations can have on both the environment and its inhabitants. The increase of gelatinous zooplankton directly affects the human population both physically and indirectly. -
