 ABSTRACT = {Humans' protracted maturation before childbearing is an extreme
             example of a general characteristic of higher organisms: a positive
             lower bound on ages of procreation. The pre-procreative span, much
             discussed for its evolutionary and social ramifications, has
             consequences also for the mathematics of population renewal....This
             paper proves the presence of a pre-procreative span sufficient, in
             and of itself, to guarantee the existence condition for bifurcation
             for all models in one important class. The class includes the best-
             studied examples of age-specific systems with and without
             homeostatic feedback in purely discrete and in purely continuous
             formulations.},

 ABSTRACT = {Comparison of the patterns of episodic secretion of two or more
             hormones measured simultaneously often suggests that peak levels
             tend to occur at around the same time. This visual impression can
             be misleading, however, as some peaks will occur simultaneously due
             to chance alone. Traditional cross-correlation methods are suitable
             for evaluating linkages among circadian and other smoothly varying
             rhythms, but are less well suited to correlating ultradian peaks.
             This paper proposes a method which entails identifying peaks of
             hormone secretion as discrete events in several different series,
             and counting the frequency of simultaneous and near-simultaneous
             peaks in temporal `windows' of increasing width. The expected rates
             of random coincidences can be assessed by a variety of methods,
             including simulations and probability calculations. The method
             described utilizes simple techniques which make few assumptions
             about the character or stationarity of the series, comparing
             coincidence rates in the appropriately paired series with those in
             which a series in one subject is deliberately `mismatched' with
             that of another subject. Using this approach, a significant excess
             of simultaneous peaks of luteinizing hormone (LH) and prolactin was
             found in normal subjects as compared with mismatched series ($17\%$
             versus $6\%$; $p < 0.05$). Hypogonadotrophic men treated with
             pulsatile gonadotrophin-releasing hormone (GnRH) have an even
             higher coincidence rate ($26\%$). By contrast, the rate of
             coincidence between pulses of LH and Cortisol is not significantly
             greater than that which would be expected due to chance.},

 ABSTRACT = {The performance of formal demographic feedback models, like Ronald
             Lee's, provides a test of whether theories of endogenous fertility
             adjustment, like Richard Easterlin's, can explain the cyclic swings
             in U.S. and other births that they were designed to explain. This
             paper shows how the specification of a demographic feedback model
             determines its ability to sustain cycles of a given period and
             amplitude observed in data. Only a few of the many versions of
             Easterlin-style theories imply formal models which do prove capable
             of matching U.S. targets, and then only by narrow margins. The
             general methods presented here are suitable for a broad
             investigation of the possible role of age-specific feedback in the
             diversity of more and less cyclic patterns in birth series in the
             developed world.},
