Temporal trends in gonococcal population genetics in a high prevalence urban community.

Molecular evolutionary studies can provide insights into the spread of infectious diseases and inform infection control measures. We performed a population genetic analysis of gonococcal isolates obtained over a 15-year interval in Baltimore, MD, where gonorrhea is highly prevalent. Categorical analysis of genetic differentiation revealed temporal structuring of the gonococcal population. The use of a new method to determine the historical demography of Neisseria gonorrhoeae from sequence data showed a strong correlation with trends in the number of reported cases of N. gonorrhoeae. The historical trends may also reflect the influence of social and demographic factors and the impact of antimicrobial resistance on the molecular epidemiology of gonorrhea in Baltimore over the past 2 decades. The strong correlation between the population genetic inferences over the last 20 years and the demographic data collected over the same time period demonstrates the utility of these approaches for the accurate inference of complex population dynamics using multilocus sequence data. The real time application of population genetic analysis can provide sentinel data on gonococcal prevalence, antibiotic resistance patterns and changing epidemiology of gonococcal infections.

Women, labour and fertility: population growth in nineteenth century Java.

The sharp increase in Java's population after 1830 is usually explained in terms of higher living standards and consequent lower mortality resulting from Dutch colonization, but there is little historical evidence supporting such an interpretation and much to refute it. An alternative view is that Java's population growth after 1830 was due to increasing fertility. The major constraint to Javanese fertility prior to this period has been extended periods of postpartum abstinence, the length of which was determined by the duration of breastfeeding, because people believed semen had deleterious effects on breast milk. In 1830 a system of forced cultivation of export crops was imposed by the Dutch rulers and greatly increased the amount of labor which Javanese households required to reproduce themselves. The arduous work women began to undertake made it increasingly difficult to breastfeed their children. As the average period of breastfeeding fell, the average period of postpartum abstinence declined and fertility increased.

Historical demography: achievements and prospects.

Historical demography as a separate discipline came into existence when family reconstruction was first developed for the analysis of a pre-transition population. This paper assesses the significant achievements made in this field of population studies since then. Attention is also paid to equally significant findings obtained from aggregative analysis based on back projection, and to a large body of research results for the period of the demographic transition. In the last part of the paper, new research directions are discussed. Data issues as well as methodological ones are raised. Special attention is given to newly emerging Asian historical demography where different source materials require different methods and techniques, which in turn are expected to broaden the scope of the so far disproportionality fertility-oriented field. Finally, discussions are extended to economic, cultural and institutional aspects of the subject, with a plea not to isolate demographic analysis from other branches of historical research.

[Population of Japan in the Meiji-Taishyo era: a reestimation].

After reviewing previous estimates of the Japanese population in the pre-censal years from the 1860s to 1920, the author presents a reestimation for this period based on more recent studies in historical demography and on Coale and Demeny's regional model life tables. "The most important revision in the present estimation [is] that life-table death rates...for the Meiji-Taishyo era are estimated by Gompertz curves with upper and lower limits in place of the former linear curves."
