[The population law (author's transl)].

Population Law is not the same at all times and in all places. Each economic stage of development has its own population law. The different development of the means of production changes the conditions. Future conditions of economy are going to be significantly different from those in the past. First the reduction of the number in population, second the changing age structure of the population, third the saturation with many material goods, fourth the decrease of the domestic growth of the gross national product and distribution, fifth in creasing environmental problems with resistance to tolerate polluting industries, sixth changes in the world economic division of preoduction with an increased production of manufactured products from developing countries, and seventh growth in the population lead to a sifting effect which pushes the weaker groups of the population into a subproletareate.

Megakaryocyte polyploidy as a grouped geometric distribution obeying the log-normal population law.

Discrete nuclear lobe scores and flow- or image-cytometry DNA values of classically identified megakaryocytes behave as a grouped geometric distribution. This model is fully specified by a geometric mean and standard deviation (GM and GSD), the latter typically being ca 1.16 for volumes of diploid blood cell populations. Via log-normal probability paper, the 30 to 50 megakaryocytes in clinical marrow smears readily yield the ploidy model's GM and GSD which are named MPM and MPD for megakaryocyte polyploidy median and dispersion. In euthrombopoietic outbred mammals, MPMs are ca 12N ploidy units, and MPDs approximate a factor of 1.41. Both are unitless criteria. Thus, the thrombon is characterized by three populations exhibiting the high size dispersion which unmasks canonical operation of the log-normal population law: picoliter megakaryothrombocytes with their MPD ca 1.41, femtoliter thrombocytes with a volume GSD ca 1.74, and the end product of locally delivered pieces of subattoliter platelet dust with a volume GSD ca. 2.0.

The economic law of population distribution and migration.

"The economic law of population distribution and migration has been studied chiefly based on the Chinese situation. The distribution and development of productive forces decide the distribution and migration of population, and in turn, the latter influences the former. The population distributions in three different stages of social development, namely agricultural, industrial and information society, are described. A new concept in population economics is introduced, i.e. population economic density, which is different from the concept of population density. The formula of population economic density is P(population)/R(resources). Many kinds of migration are analysed, and it is believed that the main efficient cause of migration is economy."

[Main points in the Population Screening Law].

The 'Wet op het Bevolkingsonderzoek' (WBO = Population Screening Act) makes certain categories of population screening subject to licensing. Licences will be granted only on the conditions that the benefits of the proposed screening outweigh its (physical and psychic) risks for those involved, and that it will be implemented correctly and expertly. The licensing authority is the Ministry of Welfare, Health and Sports, while the Health Council has an advisory function. The assessment may take several months. The above ministry issues a booklet on the procedure of applying for a licence and an application form. The address is: Directie Gezondheidsbeleid, P.O. Box 5406, 2280 HK Rijswijk, the Netherlands. The reports on three test evaluations and the list of test requirements are to be had from the Health Council. The address is: P.O. Box 1236, 2280 CE Rijswijk, the Netherlands.

Governing population genomics: law, bioethics, and biopolitics in three case studies.

Existing scholarship on population genomics has only superficially addressed issues of power and political process. Accordingly, questions of politics and governance pervade the analysis of three population genomics case studies that follow: the Human Genome Diversity Project, Iceland's Health Sector Database, and "Clinical Genomics" as defined by the Beth Israel-Ardais collaboration. An examination of these case studies reveals that the common law, U.S. regulatory law, and international law have not developed the political sophistication to make the traditional promises of biomedical ethics--respect for autonomy, justice, and beneficence--come to fruition. Further, comparisons of these projects illuminate three areas ripe for reframing--informed consent, expert ethical oversight, and commercial benefits. Four avenues of reform are suggested.

Generalized Verhulst laws for population growth.

The growth or decay of population of a single species interacting with a large number of other species (or environment) according to the Volterra-Lotka model is investigated. When the environment is initially very close to its equilibrium level, the growth of a single species follows a generalized Verhulst law, containing hereditary effects. The derivation, modeled on statistical mechanical theories of Brownian motion, leads also to a "noise" source and to its relation to the heredity kernel. A special case, where the hereditary kernel is a damped exponential function of time, is solved numerically. When growth starts at a level much below equilibrium, the population first overshoots equilibrium and then approaches it. When decay starts at a level much higher than equilibrium, the population first decays precipitously to a very low level and then slowly grows toward equilibrium.

Judgment, 22 January 1988.

The Conseil d'Etat of France affirmed the judgment of the Administrative Tribunal of Strasbourg refusing to register a surrogate motherhood association (Annual Review of Population Law, Vol. 13, 1986, Section 250). It held that the goal of the association was contrary to Article 352-1-2 of the Penal Code, which punishes incitement to the abandonment of a child. In 1988, the Court of Appeal of Aix-en-Provence upheld the judgment of the Court of First Instance of Marseilles dissolving the surrogate motherhood association Alma Mater (Annual Review of Population Law, Vol. 14, 1987, Section 250). See Le Monde, 2 May 1988, p. 8.
