The classification scheme was not difficult to apply because it reflects what the BRRC does on a daily basis in determining subject treatment protocol eligibility.
Abbreviations: AC = anterior commissure, ACA = anterior cerebral artery, ahPCG = arm-hand region of precentral gyrus, BRRC = Brain Rehabilitation Research Center, CIMT = constraint-induced movement therapy, CT = computed tomography, DTT = diffusion tensor tractographic, fMRI = functional magnetic resonance imaging, MAL = Motor Activity Log, MCA = middle cerebral artery, MRI = magnetic resonance imaging, PC = posterior commissure, PVWM = periventricular white matter, SD = standard deviation, UL = upper limb, VA = Department of Veterans Affairs.
The shift in 1966 of the recycling bureau's name, from the Beijingshi feipin (old commodities) huishou gongsi to the Beijingshi wuzi (resource) huishou gongsi (BRRC), highlighted a change that had already occurred in material practice.
This shift to a more disposable life-style was abetted by the fact that the two thousand BRRC collection points were themselves being treated as disposable; they were rapidly being gobbled up in Beijing's real-estate boom.
With the land speculation binge in the 1980s, the little plots of essentially rent-free land that the BRRC used as collection points were quickly scooped up to be used for all sorts of more profitable real estate investments.
As quickly as the BRRC network disappeared, migrants began replacing it with a new, far more dynamic, labor-intensive network that serviced these businesses.
Since 1998, however, the municipal administration, with the BRRC taking the lead, seems to have a new goal: to get a share of the profits from the recycling industry.
The stakes here are quite high for the Beijing government and the BRRC. By 1997 the BRRC employed fewer than 2,000 full time workers (with 2,000 early retirees on payroll) down from over 12,000 in 1990; collection points had fallen from over 2,000 to just 6; tonnage processed fell from over 60,000 to less than 14,000 while types of materials handled fell from 21 to only 5 (Hou 1999).
