Genetic analyses of a seasonal interval timer.
Seasonal clocks (e.g., circannual clocks, seasonal interval timers) permit anticipation of regularly occurring environmental events by timing the onset of seasonal transitions in reproduction, metabolism, and behavior. Implicit in the concept that seasonal clocks reflect adaptations to the local environment is the unexamined assumption that heritable genetic variance exists in the critical feat...
متن کاملThe timer-game: a variable interval contingency for the management of out-of-seat behavior.
The timer-game was demonstrated to be a practical and effective procedure for managing the out-of-seat behavior of elementary school children in a remedial classroom. The timer-game allowed the students to earn token reinforcement by being in their seats whenever the bell of a kitchen timer rang. The bell rang about once every 20 minutes. In a second experiment, peer reinforcement was applied i...
متن کاملA PER/TIM/DBT interval timer for Drosophila's circadian clock.
Circadian rhythms in Drosophila are supported by a negative feedback loop, in which PERIOD (PER) and Timeless (TIM) shut down their own transcription as they translocate once a day from the cytoplasm of clock-containing cells to the nucleus. Period length is partially determined by an interval of cytoplasmic retention of the TIM and PER proteins. To study this process, we examined PER/TIM/Doubl...
متن کاملPERIOD–TIMELESS Interval Timer May Require an Additional Feedback Loop
In this study we present a detailed, mechanism-based mathematical framework of Drosophila circadian rhythms. This framework facilitates a more systematic approach to understanding circadian rhythms using a comprehensive representation of the network underlying this phenomenon. The possible mechanisms underlying the cytoplasmic "interval timer" created by PERIOD-TIMELESS association are investig...
متن کاملComputing tolerance interval for binomial random variable
Tolerance interval is a random interval that contains a proportion of the population with a determined confidence level and is applied in many application fields such as reliability and quality control. In this educational paper, we investigate different methods for computing tolerance interval for the binomial random variable using the package Tolerance in statistical software R.
