(n.) The system of Malthusian doctrines relating to population.
Example Sentences:
(1) This paper is concerned with the connection between two classes of population variables: measures of population growth rate--the Malthusian parameter, the net reproduction rate, the gross reproduction rate, and the mean life expectancy; and measures of demographic heterogeneity--population entropy.
(2) The well-known disagreement between Malthusian and Marxian viewpoints therefore has its foundation in method.
(3) This paper presents a unified account of the properties of the measures, Malthusian parameter and entropy in predicting evolutionary change in populations of macromolecules, cells and individuals.
(4) The final section analyses the consequences of adopting a neo-Malthusian view, and it is shown that in a world dominated by an elite, this can frequently bring about the political, social, and economic repression of a non-elite.
(5) The neo-Malthusian population concept originated in the international agencies, who saw fertility control as a solution to global economic problems.
(6) Whatever the ideology--Malthusian or Marxist--there is no doubt that population is closely linked to development variables, of which health is a part.
(7) The desire for control is predicated on the Malthusian idea that there is a finite number of people a country can sustain without compromising standards of living.
(8) Neo-Malthusians, publishing in popular rather than scientific journals, are predicting dire results from rampant population growth and recommending coercive remedies, e.g., mass sterilizations, child rationing, and controlled extermination.
(9) Using a relation between these measures and the Malthusian parameter, it is shown that in a random mating population in Hardy-Weinberg equilibrium, and under slow selection, the rate of change of entropy is equal to the genetic variance in entropy minus the genetic covariance of entropy and reproductive potential.
(10) These properties, which are valid for populations of macromolecules, cells and individuals, show that the Malthusian parameter and entropy act as complimentary fitness indices in understanding evolutionary change in populations.
(11) Autocrine controls are described as modifiers of the Malthusian growth rate (r), while paracrine controls modify the carrying capacity (K) of the system.
(12) Family planning is seen as a means of helping to improve the socioeconomic problems that lie at the base of the Malthusian dilemma.
(13) The economic development in Brazil in the 1950s was the basis of accepting neo-Malthusian reasoning.
(14) The reproductive potential measures the mean of the contribution of the different age classes to the Malthusian parameter.
(15) Entropy determines population stability: the gain in the Malthusian parameter due to small fluctuations in the life-cycle variables is determined by entropy.
(16) The Malthusian parameter is precisely the difference between the entropy and the reproductive potential.
(17) It is shown that only a population with development rates maximizing the Malthusian function (reaching zero value at the equilibrium state of the system) is able to survive under competition for food resources.
(18) They were dominated by the new Malthusian nightmare, the tussle with malaria, the eradication of smallpox, the improved control of some other serious infections, the struggles for family planning, breast-feeding, immunization, and clean water, among other things, and above all, perhaps, by the decline of the doctor and the rise of the planner and manager.
(19) It is shown that a Malthusian or neo-Malthusian view of the population problem is inevitable if enquiry is founded in empiricism or in normative analytics.
(20) First, the coefficient of variation in population size appears to be inversely related to the Malthusian parameter of population growth.
