description of the techniques, computer programs are described which
may be used to carry out the required calculations." The geographical

"In this
paper, I will first introduce a method for the detection of the zones
of abrupt change of spatialized variables, originally conceived in the
frame for research on the biology of population, and christened
generalized Wombling....This method can be used to identify the zones
of rupture of demographic variables and of any spatialized variables in
general. Then, as an example, I will perform a generalized Wombling to
identify the zones of rupture of real (the local mobility in France
around 1900) and simulated data representing a set of uncorrelated and
correlated variables."

This work concerns the dynamics of
infectious diseases. The author presents a framework for organizing
the diverse mathematical models that have been developed to study these
dynamics. He develops the general mathematical theory and considers a
broad range of examples that can be treated within the frameworks
described. Some consideration is given to HIV infections and AIDS as a
case study.

This
study concerns the modeling of contacts between individuals in
epidemiological studies. The authors "review briefly our mixing/pair
formation framework and illustrate its application to population models
of the type currently used in demography, epidemiology, and social
dynamics. A new application to frequency dependent competitive
interactions is discussed in more detail. Connections between
deterministic and stochastic processes are presented. The results of
the simulations of a demographic two-sex stochastic model that follows
the dynamics of pairs are presented."

case-control studies are of particular interest whenever direct

upon two applications...,in order to demonstrate the usefulness of the
case-control method for better investigation of mortality rates and
differentials in various contexts." The geographical scope is

a small Australian city....Although estimates produced by this method
should be validated with other techniques it provides a simple, quick
method to estimate the numbers of people in other hidden populations

"Transmission of cultural traits
behaves superficially like genetic transmission, but is substantially
more complicated, since transmission is influenced by the population at
large, as is disease transmission. We present a framework for modeling
cultural transmission by a system of ordinary differential equations,
with nonlinearities both in the transmission and in the formation of
pairs....Our objective here is to illustrate the use of our axiomatic
approach for the construction of dynamic models that may prove useful
in the study of the propagation or survival of social traits such as
religion and language."

Time-varying covariates in models of human mortality and aging:
multidimensional generalizations of the Gompertz. Journal of
Gerontology: Biological Sciences, Vol. 49, No. 4, Jul 1994. B169-90
pp. Washington, D.C. In Eng.
"Models of mortality and aging depend
on assumptions about physiological change even if they are not made
explicit. Standard models, like the Gompertz, often fail to describe
mortality at extreme ages, suggesting a need for biologically more
detailed and flexible models. One solution is to model the interaction
of time-varying covariates with mortality to better describe the age
dependence of mortality, test hypotheses about the relation of
physiological change and mortality, and use longitudinal data to
generalize assumptions about physiological change. This model is
applied to (a) a 34-year follow-up of risk factors and mortality and
(b) a 9.5-year follow-up of function and mortality from longitudinal
surveys of the U.S. elderly population."

have...tried in the past [to] generate estimates of the parameters of a
stable population model....In an earlier paper, Mitra and Levin (1990)
experimented with a generalized model....Among other things, that model
generated a pair of nonlinear equations from which the intrinsic roots,
real as well as complex, had to be solved. The purpose of this paper
is to present an alternative method of solving the same pair of
equations which reveals another set of interesting features
characteristic of this different approach."

the schedules of vital rates change over time but where there is a
sequence of rate schedules that repeats itself indefinitely....The

application of cyclical stationarity to contemporary U.S.

influenced by the group affiliations of persons with multiple

of this mixing is compared with some existing modelling formats, and
some preliminary simulations are presented for the timing and spread of
