TL;DR: In this paper, the authors show the need for a new model of consumption by making clear the descriptive and normative shortcomings of consumer sovereignty, and propose a new sustainable consumption model to serve as a guideline for both responsible consumers and consumer policymakers and for all institutions concerned with the creation of sustainable development.
Abstract: The importance of consumption in modern societies is constantly growing. To guide consumer oriented policy, a model of consumption is needed which reflects consumers increased significance. The model of consumption prevailing in the theory of market economies as well as in consumer policy was traditionally based upon the notion of consumers sovereignty. This model served both as a description and as the ethical foundation of the market economy. In the first part of this paper, the authors show the need for a new model of consumption by making clear the descriptive and normative shortcomings of consumer sovereignty. In view of the reality of modern societies, it is neither possible nor ethically justifiable to make purchase decisions according to the individual maximization of utility only. The second part presents the idea, the ethical foundation, and the contents of the new model of "sustainable consumption." This model is proposed to serve as a guideline for both responsible consumers and consumer policymakers and for all institutions concerned with the creation of a sustainable development.

TL;DR: In this paper, the authors tested the validity of GIBRAT's Law of proportionate growth and found that the law is only valid for very few groups of firms in some of the periods covered.
Abstract: Using data for some 7000 manufacturing establishments from Lower Saxony for 1978–1989 we tested for the validity of GIBRAT's Law of Proportionate Growth. We found that the law is only valid for very few groups of firms in some of the periods covered. However, we did not find that small firms grew systematically faster or slower than larger firms, or vice versa. On the other hand, we found ‘persistence of chance’ in the sense that a firm grows faster if it happened to grow faster in the past, too.

TL;DR: This is the first report demonstrating an Al-exclusion mechanism in soybean cultivars, which is conferred by enhanced and specific Al-induced exudation of citrate, found to be specific for Al.
Abstract: Fourteen soybean (Glycine max [L.] Merr.) cultivars were analysed and found to differ considerably in aluminium (Al) resistance. The cultivars Suzunari (Al-resistant) and Shishio (Al-sensitive) were selected for further analysis of physiological mechanisms of Al resistance. The relative root growth of Shishio was 48% compared to 76% for Suzunari in response to 15 μM Al (24 h). Aluminium accumulation and Al-induced callose formation in root apices were 50 and 25% of that in Suzunari, respectively. Al inhibited both Suzunari and Shishio during the first 6 h of exposure. However, the root growth inhibition was further increased in Shishio but not in Suzunari, suggesting an Al-induced Al-resistant mechanism operating in Suzunari. Organic acid analysis in root exudates of both cultivars revealed that they specifically exuded citrate in response to Al. However, the citrate exudation rate was significantly higher in Suzunari during the 6 h/24 h Al treatment, which was 52/330 compared to Shishio's 26/118 (nmol [g root fresh weight] -1 [6 h] -1 ), respectively. This Al-induced citric acid exudation was found to be specific for Al, as several other metals failed to induce citrate exudation in both cultivars. Fourteen days of P deficiency did not elicit citrate excretion in both cultivars, while application of Al to P-deficient plants rapidly induced citrate exudation in both cultivars, confirming the specificity of the response of these soybean cultivars to Al. To our knowledge, this is the first report demonstrating an Al-exclusion mechanism in soybean cultivars, which is conferred by enhanced and specific Al-induced exudation of citrate.
