TL;DR: Cheek-pouch dispersal by monkeys has possibly enhanced the natural selection for larger seeds which bring forth larger seedlings with high shade-tolerance in trees in the mature stand in a warm temperate evergreen forest on Yakushima Island.
Abstract: Seed dispersal by Japanese monkeys (Macaca fuscata yakui) via cheek-pouch was studied in a warm temperate evergreen forest on Yakushima Island. Plant list was compiled based on a study during 1986–1995, of which troops of monkeys have been habituated without artificial feeding. We followed the well-habituated monkeys in 1993 and 1994 to observe the feeding behavior and their treatments of fruits and seeds, and collected seeds dispersed by monkeys to record the distance carried from the mother trees. We checked the difference of germination ratio between seeds dispersed via cheek-pouch and seeds taken from mother trees by sowing experiments. Seeds and acorns of 22 species were observed to be dispersed via cheek-pouch of monkeys. Among them, three species with acorns were never dispersed via feces, and 15 species with drupes were seldom dispersed via feces. Plant species of which seeds are dispersed only via cheek-pouch had larger seeds than those of dispersed both via cheek-pouch and via feces, and typically had only one or two seeds in a fruit. As for one of cheek-pouch dispersal species,Persea thunbergii, the mean distance when seeds were carried from the mother trees via cheek-pouch was 19.7 m, and the maximum distance was as long as 105 m although more than 80% of seeds were dispersed within 30 m from mother trees. And 82% of seeds dispersed via cheek-pouch germinated. The easy separation of seeds from other parts of the fruit seems to facilitate cheek-pouch dispersal more than dispersal via feces. Cheek-pouch dispersal by monkeys has possibly enhanced the natural selection for larger seeds which bring forth larger seedlings with high shade-tolerance. In conclusion, cheek-pouch dispersal by monkeys is quite an important mode for trees in the mature stand in a warm temperate evergreen forest on Yakushima Island.

TL;DR: The authors analyzes a model of duopoly with heterogeneous goods where behavior patterns are endogenously determined by producers, and proves non-equivalence of tariffs and quotas in the duopoly situation where the pricing behavior of the producers is not the monopolistic behaviour of the domestic producer over consumers, but a certain kind of his behavior against the foreign producers.

TL;DR: This paper proposes a simulation system to support designing supply chain management operations and demonstrates simulations of the typical forms of supply chain systems: these are ‘centre-controlled ordering system’, ‘vendor reorder-point system”, and ‘pull-operational system�’.
Abstract: This paper proposes a simulation system to support designing supply chain management operations. The most remarkable characteristic of this simulation is to represent business process activities in supply chain management. The organisation-based models are described in this paper. Activities of these models include supply-chain management operations, such as ‘demands predictions’, ‘manufacturing planning’, ‘material purchasing’, ‘manufacturing and transportation ordering’, and ‘products shipping’. These models also represent activities in manufacturing and transportation operations. This paper further demonstrates simulations of the typical forms of supply chain systems: these are ‘centre-controlled ordering system’, ‘vendor reorder-point system’, and ‘pull-operational system’. Finally, these simulation results are compared in view of supply chain performance.

TL;DR: In this paper, the authors established a "packaging visual-gustatory correspondence effect" whereby the image of a food product placed at the bottom (vs. top) of the package facade enhances consumers' expectations and actual perceptions of the food's flavor heaviness.

TL;DR: In this paper, the authors analyzed the relationship between the industrial agglomeration effect and the energy efficiency of each studied industry and found that the same industry aggregates contribute to improvements in energy efficiency in the paper and pulp industry.
