Qing history in America: past accomplishments and present trends
Get PDFFifty years ago, Chinese history hardly existed as a field of
study in the United States. In 1935, there were no more than a dozen
active American sinologists of whom only one or two were historians.1
Today there are over sixteen hundred members of the Association of
Asian Studies who study China, of whom at least seven hundred are
historians and one hundred are social scientists who work extensively
with historical material. 2 Chinese studies has made vast strides
largely under the banner of area studies. History, especially Qing
history, has predominated. Qing historians have their own journal and
their own professional association with a membership of well over three
hundred individuals.3 They account for almost half of all Chinese
historians and receive the bulk of all historical funding

The metastable birth trajectory
Get PDFThe metastable model generalizes the stable population model by allowing net maternity to change exponentially over age and time. As a result, the metastable model generates an exponentially quadratic birth trajectory, which is characterized by a constant proportion of births by age of mother. The metastable model is well suited to analyzing steady fertility declines and transitions between two regimes of fixed vital rates.dynamic population models, metastable population, quadratic exponential trajectory, stable population
