Optically Stimulated Luminescence dating, grain-size analysis and magnetic susceptibility measurements were conducted on the Fanjiaping loess section, from the western Chinese Loess Plateau. The results confirm that last glacial high-frequency climatic shifts were documented in mid-latitude continental archives. The grain-size record indicated that coarse-grained sediments with horizontal bedding and channel-fill structures were only deposited in several short intervals, equivalent to the beginning of marine oxygen isotope stage (MIS) 4 and the early to middle MIS 3. This probably implies brief rainfall intensification of the Asian summer monsoon, and its disappearance since the late MIS 3 to MIS 2 may have been a response to significant glacial cooling in the Northern Hemisphere. Previous investigations revealed high sea-surface temperatures at high latitudes at the start of MIS 4, and the early to middle MIS 3 intensification of summer insolation in the Northern Hemisphere, implying evident climate amelioration. Climate improvement favors boreal forest recovery, enhancing both winter and summer air temperatures. The resultant smaller equator-polar temperature gradient probably helped the moisture-laden summer monsoon to penetrate northward. This study thus provides new significant information about the response of terrestrial loessic palaeoenvironments to millennial-timescale climatic fluctuations during the last glacial period.

In the broader social science literature, most studies of social protection investigate welfare in democracies, and at the national level, and typically assume that welfare is given in order to influence voting. This paper, to the contrary, considers social assistance in authoritarian China at the urban level. Its findings are compatible with an explanation that there are two dissimilar logics influencing the distributional decisions of lower-level administrators. That is, there appear to be two modes of social policy implementation, which vary with the fiscal capacity of a given city, as indicated by its average wage: Wealthier cities seem to prefer to push off the streets those viewed as unsuited to a modern city, therefore allocating a substantial proportion of their social assistance funds to them, in order to entice them to stay at home. On the other hand, poorer places seem to permit such people to work outside, in the hope that they will thus be better able to support themselves, thereby saving the city money. A data set from China's Ministry of Civil Affairs was used.
