    Brood size and the cost of provisioning nestlings: interpreting Lack's hypothesis (1993)
    Springer
    Oecologia 96 (1993), S. 290-292 
    Details
    ISSN: 1432-1939
    Keywords: Lack's hypothesis ; Parental investment ; Feeding nestlings ; Clutch size ; Tradeoff model
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A recent model of parental provisioning (the “tradeoff model”) suggests that the maximum delivery rate of food to nestlings represents a tradeoff between parental residual reproductive value and nestling survival. In contrast, Lack's hypothesis suggests that maximum provisioning rate determines brood size and therefore delivery rates are limited by shortages of food or foraging time, not by tradeoffs of parental investment. Several authors have examined the shape of the per-nestling feeding curves to test the tradeoff model against Lack's hypothesis. We show that Lack's hypothesis can produce per-nestling feeding curves consistent with the tradeoff model. Therefore, the shape of the per-nestling feeding curve cannot be used to distinguish between the models.

    Doxazosin in patients with hypertension (1988)
    Springer
    European journal of clinical pharmacology 35 (1988), S. 21-24 
    Details
    ISSN: 1432-1041
    Keywords: doxazosin ; hypertension ; alpha-adrenergic blockade ; bioavailability ; pharmacokinetics ; adverse effects
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The antihypertensive effects and steady-state pharmacokinetics of doxazosin, as well as the bioequivalence of four dosage forms, were studied in 25 hypertensive patients. For an 8 mg daily dose mean Cmax at steady-state for all patients was 108 ng/ml; the mean tmax was 1.8 h. The mean terminal elimination half-life was 22 h. The four tablets containing 1, 2, 4, or 8 mg of doxazosin were bioequivalent in delivering the 8 mg dose. In patients with mild to moderate hypertension, 26-day treatment with doxazosin resulted in blood pressure reduction of 10/7 mm Hg in the supine and 13/18 mm Hg in the standing position. Adverse effects were generally mild and of brief duration.

    Energy Tax and Competition in Energy Efficiency: The Case of Consumer Durables (2000)
    Springer
    Environmental and resource economics 15 (2000), S. 159-177 
    Details
    ISSN: 1573-1502
    Keywords: energy saving technical change ; consumer durables ; second best energy tax ; price competition
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering , Economics
    Notes: Abstract The purpose of this paper is to analyze the role of anenergy tax on technical improvements and on prices ofconsumer durables induced by strategic competition inenergy efficiency. If the gasoline tax is raised thisdoes in principle not affect the producers of carsbecause the motorist pays for it in terms of a highercost of using the car. This, however, affects the unitsales of car producers because of substitution towardsother modes of transportation. A second element ofreaction to energy price variation is an indirect oneand relates to the effect of energy prices ontechnology. Competition forces car producers todevelop more energy efficient cars in order to reducethe cost of using a car. This indirect effect canpartly offset the direct effect of higher energyprices on demand if it is profitable for theautomobile industry to engineer more energy efficientequipment. We will analyze the impact of an energy taxon energy efficiency and on the price of a durablegood. This will be done within the framework of aduopoly competing in prices and in the energyefficiency of its products. The government chooses awelfare maximizing energy tax as an incentive toinnovate. Then we will analyze a strategic two-stagedecision process in which the duopolists first decideabout energy efficiency and then compete in prices.
