Springer Science and Business Media LLC - Tập 22 - Trang 355-363 - 2001
This article is a synopsis of a UN study, with emphasis on Italy and the United
States. In March, 2000, the United Nations Population Division published a
143-page booklet entitled, Replacement Migration: Is It a Solution to Declining
and Aging Populations? Five projections were developed for eight countries:
France, Germany, Italy, Japan, Republic of Korea, Russian federation. United

A suggested framework for analysis of urban-rural fertility differentials with an illustration of the Tanzanian case
Springer Science and Business Media LLC - Tập 3 - Trang 237-261 - 1980
This paper offers a framework for analyzing how individual characteristics and
urban or rural "place" factors interact to influence fertility decisions. The
framework builds on the Davis-Blake model and additionally shows how place or
community variables influence exposure to intercourse, conception, and birth,
either with or without a conscious decisionmaking process. The framework
emphasizes the...
The proximity of others: A critique of crowding research and integration with the Social Sciences

The Sierra Club Immigration Debate: National Implications
Springer Science and Business Media LLC - Tập 20 - Trang 401-412 - 1999
U.S. population doubled during the past 50 years with nary a notice by anyone,
why expect anything different during the next doubling? The relationship between
U.S. population size and environment suddenly became newsworthy for six months
in 1997–98, thanks to a bruising battle within the Sierra Club. Whether or not
you are a Sierra Club member, please consider becoming involved in a rare
opportun...
How bad will it be? Modelling the AIDS epidemic in Eastern Africa
Springer Science and Business Media LLC - Tập 14 - Trang 265-278 - 1993
The spread of HIV infection and the subsequent AIDS morbidity and mortality
threatens to have a substantial impact on societies in subSaharan Africa.
Infection levels are increasing rapidly in many regions, especially in urban
areas. The consequences of high levels of infection are inescapable, although,
due to the long incubation period, morbidity and mortality increases lag several
years behind ...

The greenhouse gas methane (CH4): Sources and sinks, the impact of population growth, possible interventions
Springer Science and Business Media LLC - Tập 16 - Trang 109-137 - 1994
Methane (CH4) is one of the trace gases in the atmosphere that is considered to
play a major role in what is called the “greenhouse effect.” There are six major
sources of atmospheric methane: emission from anaerobic decomposition in (1)
natural wetlands; (2) paddy rice fields; (3) emission from livestock production
systems (including intrinsic fermentation and animal waste); (4) biomass burning

Population and sustainable development: Distinguishing fact and preference concerning the future human population and environment
Springer Science and Business Media LLC - Tập 14 - Trang 441-461 - 1993
The relation of population, environment and economic growth is controversial,
with some considering that growth comes at an intolerable expense to the
environment, others that the damage to the environment is slight and in any case
so far in the future that it does not matter. Scientific evidence on the subject
is not the only basis on which people choose sides; major factors are preference
for pr...
Conceptual dimensions of crowding reconsidered
Springer Science and Business Media LLC - Tập 3 - Trang 298-308 - 1980
A recent and noteworthy facet of crowding research has been the exploration of
the perception of high density/crowding experiences. A review of the methods and
results of these investigations reveals considerable variation across studies on
the dimensions of stimulus domain and selection, attention to intersubject
differences, and approaches to interpreting results. The outputs of these
studies do...
