A runaway is a minor or ... Runaways have an elevated risk of destructive behavior. Approximately fifty percent of runaways experience difficulties with schooling; ...
The runaway greenhouse effect is often formulated in terms of how the surface temperature of a planet changes with differing amounts of received starlight. [13] If the planet is assumed to be in radiative equilibrium, then the runaway greenhouse state is calculated as the equilibrium state at which water cannot exist in liquid form. [3]
The peacock tail in flight, the classic example of an ornament assumed to be a Fisherian runaway. Fisherian runaway or runaway selection is a sexual selection mechanism proposed by the mathematical biologist Ronald Fisher in the early 20th century, to account for the evolution of ostentatious male ornamentation by persistent, directional female choice.
The term derives from the Greek δραπέτης (drapetēs, 'a runaway [slave]') and μανία (mania, 'madness, frenzy'). [ 9 ] As late as 1914, the third edition of Thomas Lathrop Stedman 's Practical Medical Dictionary included an entry for drapetomania , defined as " vagabondage , dromomania ; an uncontrollable or insane impulsion to wander."
These are direct phenotypic benefits, sensory bias, the Fisherian runaway hypothesis, indicator traits and genetic compatibility. In the majority of systems where mate choice exists, one sex tends to be competitive with their same-sex members [4] and the other sex is choosy (meaning they are selective when it comes to picking individuals to ...
Possible mechanisms for this behavior include Hamilton's selfish herd theory, neighbor copying, or the byproduct of communication by social animals or runaway positive feedback. Characteristics of escape panic include: Individuals attempt to move faster than normal. Interactions between individuals become physical. Exits become arched and clogged.
Some of the 75,000 U.S. federal workers who the Office of Personnel Management says accepted a resignation buyout offer were ready to retire anyway. Many bristled at Donald Trump's description of ...
Chemical reactions involving thermal runaway are also called thermal explosions in chemical engineering, or runaway reactions in organic chemistry.It is a process by which an exothermic reaction goes out of control: the reaction rate increases due to an increase in temperature, causing a further increase in temperature and hence a further rapid increase in the reaction rate.
