 ABSTRACT = {Although the different anterior pituitary hormones are generally
             considered to be regulated independently, examination of their
             patterns in blood suggests that pulsatile secretion of several of
             these hormones may be synchronized. Traditional methods of cross-
             correlation analysis may not be adequate for quantifying this
             linkage. Since some simultaneity may arise by chance, expected
             rates of random coincidences must also be estimated to determine if
             apparent concordance rates significantly exceed those due to
             chance. A method of estimating linkage by counting simultaneous and
             near-simultaneous events within temporal'windows'of varying width
             is proposed and tested against 11 series of luteinizing hormone
             (LH) and prolactin measurements from normal men. Rates of
             concordance in series drawn from different subjects rather than the
             same subject, or series scrambled in time, do not contain
             meaningful simultaneous events and so can be used to estimate the
             rate of random synchrony. By these standards, a clear excess of
             concordant prolactin and luteinizing hormone (LH) peaks was
             observed in normal men, suggesting significant physiological
             synchrony between these pulses of secretion. This method can be
             applied to a variety of hormonal systems.},

    TITLE = {U.S. births and limit cycle models},
  JOURNAL = {Demography},
   VOLUME = {26},
     YEAR = {1989},
    PAGES = {99--115},
 ABSTRACT = {Lee's...formal demographic feedback models summarize the
             implications for births and age-structure of neo-Malthusian
             theories of baby booms like those of Easterlin. For some parameter
             values, such models imply sustained cycles, so-called 'limit
             cycles', in births. Frauenthal and Swick have recently re-estimated
             a continuous-age version of Lee's Basic Cohort Model with U.S.
             series and, contrary to Lee's original findings, have been led with
             this model to the conclusion that 'limit cycle oscillations have
             been occurring in U.S. births.' This paper disputes this
             conclusion, ascribing it to an inconsistency in detrending
             procedures. Furthermore, it corrects Lee's original conclusion by
             showing that his alternative Period Labor-Force Feedback Model,
             estimated from U.S. series, leads to cycles of implausibly long
             period. This paper thus reopens the question of whether any
             feedback model could account for the observed cycles in U.S.
             births.},
