"Cheap and nasty": German goods, socialism, and the 1876 Philadelphia world fair

At the World Fair in Philadelphia in 1876, the German goods on display were described as cheap and nasty, setting off a vigorous debate about the state of German industry. Social democrats attacked policies of increasing competitiveness of German exports through keeping wages low, and claimed that the quality of the goods produced by socialist workers was higher than those produced by others. An analysis of the debate shows the extent to which social democrats not only resorted to arguments stressing the national interest, but also the extent to which nominally Marxist socialists in this period were still attached to traditional artisanal values of pride in the quality of their work.

Thermal ionization mass spectrometry U-series dating of a hominid site near Nanjing, China

Mass spectrometric U-series dating of speleothems from Tangshan Cave, combined with ecological and paleoclimatic evidence, indicates that Nanjing Man, a typical Homo erectus morphologically correlated with Peking Man at Zhoukoudian, should be at least 580 k.y. old, or more likely lived during the glacial oxygen isotope stage 16 (similar to 620 ka). Such an age estimate, which is similar to 270 ka older than previous electron spin resonance and alpha counting U-series dates, has significant implications for the evolution of Asian H. erectus. Dentine and enamel samples from the coexisting fossil layer yield significantly younger apparent ages, that of the enamel sample being only less than one-fourth of the minimum age of Nanjing Man. This suggests that U uptake history is far more complex than existing models can handle. As a result, great care must be taken in the interpretation of electron spin resonance and U-series dates of fossil teeth.
