Coasts: form, process and evolution

Form, function, and evolution of living organisms.

Despite the vast diversity of sizes and shapes of living organisms, life's organization across scales exhibits remarkable commonalities, most notably through the approximate validity of Kleiber's law, the power law scaling of metabolic rates with the mass of an organism. Here, we present a derivation of Kleiber's law that is independent of the specificity of the myriads of organism species. Spe...

Loopholes and the Evolution of Contract Form∗

We explore a simple overlapping-generations model of the evolution via “loopholes” of incentive systems such as contracts, organizations, or regulatory regimes. Young principals, who are uncertain about what actions will be feasible for their agents, get limited observations of earlier agents’ behavior, and rationally update their beliefs about feasible actions. When old, they offer contracts t...

Evolution of Marine Mammal Hunting: A View from the California and Oregon Coasts

Marine mammals constitute ... an integral part of the marine ecosystem usually as top predators. Hunting of cetaceans and pinnipeds for skins, meat and blubber has of course gone on from the earliest recorded times. At various periods ... the hunting of them intensified to the point at which it caused serious depletion. Al­ though accurate records are not available, there is little doubt that m...

Microstructure evolution and mechanical properties of Mo40/C93200 bimetal processed by compound casting process

Compound casting refers to a process that used to produce bimetals. This study investigates the interface of Mo40/C93200 that is produced by compound casting process. In this research, molten bronze is poured around steel core, interaction between liquid and solid creates a diffusion zone and followed by a transition layer which leads to the creation of diffused region between the interfaces of...
