An alternative view offered by Richard Dawkins is of predation as a form of competition: the genes of both the predator and prey are competing for the body (or 'survival machine') of the prey organism. This is best understood in the context of the gene centered view of evolution. Another manner in which predation and competition are connected is throughout intraguild predation. Intraguild predators are those that kill and eat other predators of different species at the same trophic level, and thus that are potential competitors.

Ah, so.. Richard Dawkins

In jurisdictions using a common law system, the doctrine of stare decisis applies, whereby the principles applied by the supreme court in its decisions are binding upon all lower courts; this is intended to apply a uniform interpretation and implementation of the law. In civil law jurisdictions the doctrine of stare decisis is not generally considered to apply, so the decisions of the supreme court are not necessarily binding beyond the immediate case before it; however, in practice the decisions of the supreme court usually provide a very strong precedent, or jurisprudence constante, for both itself and all lower courts.

Ah, so.. civil law jurisdictions

In flood lamps used for photographic lighting, the tradeoff is made in the other direction. Compared to general-service bulbs, for the same power, these bulbs produce far more light, and (more importantly) light at a higher color temperature, at the expense of greatly reduced life (which may be as short as two hours for a type P1 lamp). The upper temperature limit for the filament is the melting point of the metal. Tungsten is the metal with the highest melting point, 3,695 K (6,191 F). A 50-hour-life projection bulb, for instance, is designed to operate only 50 C (122 F) below that melting point. Such a lamp may achieve up to 22 lumens per watt, compared with 17.5 for a 750-hour general service lamp.

Ah, so..
