    Notizen: Abstract The frequent charge that environmentalism is “elitist” is examined conceptually and empirically. First, the concept of elitism is analyzed by distinguishing between three types of accusations made against the environmental movement: (a)compositional elitism suggests that environmentalists are drawn from privileged socioeconomic strata, (b)ideological elitism suggests that environmental reforms are a subterfuge for distributing benefits to environmentalists and/or costs to others, and (c)impact elitism suggests that environmental reforms, whether intentionally or not, do in fact have regressive social impacts. The evidence bearing on each of the three types of elitism is examined in some detail, and the following conclusions are drawn: Compositional elitism is an exaggeration, for although environmentalists are typically above average in socioeconomic status (as are most sociopolitical activists), few belong to the upper class. Ideological elitism may hold in some instances, but environmentalists have shown increasing sensitivity to equity concerns and there is little evidence of consistent pursuit of self-interest. Impact elitism is the most important issue, and also the most difficult to assess. It appears that there has been a general tendency for environmental reforms to have regressive impacts. However, it is increasingly recognized that problems such as workplace pollution and toxic waste contamination disproportionately affect the lower socioeconomic strata, and thus reforms aimed at such problems will likely have more progressive impacts.

    Notizen: Summary A number of variants of X-linked retinitis pigmentosa (XLRP) have been described. In one variant, listed in the McKusick (McK) catalogue (McKusick 1983) as entry no. 30320, the heterozygotes exhibit a golden metallic or tapetal reflex. Three large pedigrees segregating for XLRP with the characteristic tapetal reflex in the heterozygotes were examined, and the linkage between the XLRP locus and Xp loci, L1.28, OTC, 754, XJ-1.1, pERT87 and C7 was measured. The strongest linkage was found to be between the XLRP locus and OTC. In addition, recombinational evidence drawn from the three pedigrees suggests that the XLRP locus is distal to L1.28 and proximal to 754. This putative location of the XLRP gene between L1.28 and 754 taken together with the tight linkage to OTC, a locus already located between L1.28 and 754, leads us to propose a gene order of centromere-L1.28-OTC/XLRP-754-telomere.

    Notizen: Summary The maternal inheritance in Leber optic atrophy suggests that it may be caused by a cytoplasmic or mitochondrial defect. However, the strong male bias and the strict tissue specificity can not be readily explained by a single mitochondrial gene defect alone. Wallace suggested a hypothesis that the disease could be the result of an interaction between an X-linked gene and a mitochondrial DNA defect. Linkage relationships between Leber optic atrophy and 15 X-chromosome markers were analyzed in three large Tasmanian families. The results of two-point linkage analysis showed no close linkage between Leber optic atrophy and any of the 15 markers. The results of multipoint linkage analysis suggested the exclusion of the assumed X-linked gene from almost the whole X chromosome in these families.

    Notizen: Summary In a family in which X-linked megalocornea is segregating, the disease locus was found to be closely linked to DXS87 (zmax=3.91, θmax=0.00) and DXS94 (zmax=3.34, θmax=0.00) in Xq21.3-q22.

    Notizen: Abstract The basic ideas underlying the analysis in this paper are that family size can be viewed as an economic life cycle decision and that there are decision trade-offs among fertility, consumption, and leisure. A micromodel of life cycle choice is developed and embedded in an economic-demographic macromodel. The macromodel is then used in a series of computer experiments to assess the effects on the population and the economy of changes in household preferences for children. The experiments include “factual” and “counterfactual” simulations of Canadian historical demographic experience and simulations of alternative future scenarios. The analysis and conclusions have general relevance for countries that have been through a fertility boom-and-bust sequence.

    Notizen: Synopsis Female mosquitofish,Gambusia affinis affinis, were masculinized by exposure to degradation products (presumably steroids) of the plant sterol, stigmastanol. Masculinization was indicated by the induction of a male-like gonopodium in each specimen. The morphogenetic stages of gonopodial development are discussed as are the anatomical specializations produced in the mature gonopodial tip.

    Notizen: Abstract In the heart and other mammalian tissues, there are three exclusively intramitochondrial dehydrogenases that occupy key regulatory sites in oxidative metabolism which can be activated by increases in Ca2+ in the approximate range 0.05–5 μM; they are the pyruvate, NAD+-isocitrate and 2-oxoglutarate dehydrogenases. Activation of these enzymes can be demonstrated within intact mitochondria, incubated under expected physiological conditions, when the extramitochondrial concentration of Ca+ is raised within the expected physiological range. Recent studies with fura-2-loaded mitochondria have established that matrix Ca2+ is indeed in the 0.02–2 μM range as the enzymes are activated. There is now good evidence that in the rat heart, increases in cytoplasmic [Ca2+] caused by various inotropic agents result in increases in intramitochondrial Ca2+ and activation of these dehydrogenases. It is argued therefore that matrix Ca2+ may thus be a key regulator of oxidative phosphorylation under such circumstances. The major advantage of such a mechanism of dehydrogenase-based control of this process would be to the energy homeostasis of the cell by allowing stimulated ATP production without the need to decrease the ATP/ADP ratio. Therefore it is also proposed that the major function of the mitochondrial Ca2+-transport system is to regulate matrix Ca2+, and that the ability of mitochondria to buffer the extramitochondrial concentration of Ca2+ may thus only be reserved for pathophysiological conditions of abnormal sarcolemmal Ca2+ influx as perhaps may occur in ischaemia reperfusion.

    Notizen: Abstract Putting prisoners to work has widespread appeal, but the nature of prison labor markets suggests that prisoners may have little incentive to work. The inmate population exhibits sociodemographic and psychological characteristics that correlate highly with labor market difficulties. Moreover, work incentives are bounded by both a guaranteed minimum standard of living and severe restrictions on the uses of earnings; prison is essentially a ration regime The impact of these institutional arrangements also depends upon the duration of the prisoner's remaining sentence and expected remaining lifetime. Unfortunately, there is little evidence bearing on these concerns, and experimental analysis is proposed.
